PRINTED CIRCUITS COMPONENTS FOR A JIT FACTORY Mr. Carl Burger, supply manager at Acacia Company, is faced with a problem of
researching several electronic components for a new graphic plotter, manufactured in a just–in–time environment. Acacia Company is a major producer
of graphic plotters, renowned for top–quality and innovative products. The newest unit in the product line is the 440A, a relatively inexpensive
eight–pen, A–size (8ВЅ" x 11") plotter, designed for use with personal computers. Thoughtful design of the component parts, along with a dedicated
value engineering effort, resulted in substantially fewer component parts required for assembly. Extensive market research indicated that the plotter
was priced lower than most ... Show more content on Helpwriting.net ...
The PC cell contains state–of–the–art robotics equipment requiring little human intervention. The equipment is designed to select the component parts
while still packaged, load its feeder bins, and automatically insert the components into PC boards based on a computerized XY insertion program.
There is also a JIT stockroom facility near the production areas, and a separate MRP system. Parts purchased for the 440A must meet special JIT
requirements. Suppliers are requested to use bar–coded labels to identify their shipments for optical wanding into inventory, and the automatic
equipment requires specially designed packaging tubes and parts for taping for autoinsertion of PC components. Furthermore, the delivery of most JIT
parts must be weekly (instead of usual monthly delivery), in order to maintain a minimum of inventory in the stockroom. Deliveries must be highly
reliable to prevent stockouts and line shutdowns. The parts that Carl is considering resourcing are four integrated circuits (ICs), seven diodes, and three
transistors. These parts are all low–cost, industry–standard parts, with the exception of five of the diodes, which are manufactured by only one
company, Monitor Inc. Monitor is the industry leader in diodes and transistors and supplies Acacia with quality parts at competitive prices for other
plotters. While the 440A was still in the design phase, Carl and the electrical engineers began preliminary

Ecology: Water and Aquatic Habitats
ECOLOGY
Ecology is concerned with the study of organisms and their habitats. This includes the interdependence of various populations, their impact on each
other and their surroundings, the effect of the surroundings on their behaviour, as well as the ways in which the organisms and the environment change
in response to each other. A pond and its inhabitants provide a good example of these interrelationships. A pond contains:
a.soil consisting of rock, minerals and dead remains of organisms
b.water with minerals
c.aquatic plants including algae
d.aquatic animals like snails and tadpoles
e.bacteria and other microorganisms such as protozoans
All these components interact to produce a system called an ecosystem which is constantly ... Show more content on Helpwriting.net ...
Aquatic animals prefer darker waters during the day and ascend to the surface when light intensity is reduced. Flowering of plants also depends on
light. pH This determines the acidity or alkalinity of the water in aquatic habitats or the soil in terrestrial habitats. The pH tends to be neutral at a
value of 7 and increases if alkaline contents are abundant. Organisms are affected by the pH of their environment. Fresh water mollusks tend to be
deficient on waters with a pH less than 6.
Wind
Winds carry water currents and waves and also rain–bearing clouds. Wind also helps in the dispersal of fruits and seeds and causes pollination in some
plants. The drying effect of strong air currents can cause a high rate of transpiration. The fauna and flora of mountains differ due to winds. The
windward side of mountains has luscious vegetation while the leeward side is sparsely vegetated.
Pressure
Pressure varies from the depths of the ocean to the higher altitudes of atmosphere. Atmospheric pressure reduces when one ascends from sea level.
Mountainous areas have lower atmospheric pressure than lowlands.
AQUATIC ECOLOGICAL FACTORS
Salinity is the concentration of dissolved salts in the surrounding environment. Aquatic organisms have to maintain osmotic balance between their body
fluids and their aquatic habitats. The concentration of salts in the body of marine animals is close to that in surrounding water. They are therefore able to

Spanish Moss
Spanish moss is a vascular epiphyte that belongs to the genus known as Tillandsia. Epiphytes do not typically harm the tree species that it resides on.
Epiphytes such as Spanish moss(TillansiaUaneoides) is not dependent on the tree for nutrients; however, it uses the tree for mechanical support. It
produces seeds that are transported by the wind which causes it to be found in various locations; however, spanish moss may not survive living on
some tree hosts and be found more frequently on certain tree species than others. This is largely due to the fact that biotic factors and abiotic factors
contribute to the distribution of Spanish moss found in certain environments. Biotic and abiotic factors determine both where an organism can live...

This could be due to the increased amount of foliar minerals on the dying tree, so "it is possible that differences in availability of minerals in
various tree canopies could determine the local distribution of Spanish moss"(Marks and Schlesinger 1977). The availability of minerals also plays
a crucial role with the amount of spanish moss found on cypress and hardwoods versus pine trees. Pine trees do not generally leach nearly as much
minerals as cypress and hardwood trees do. Mark and Schlesinger inferred that cypress and hardwood trees possess a higher percentage of Calcium,
Magnesium, and Potassium than pine trees(1977). The differences in minerals, host preferences and other abiotic and biotic factors of Spanish moss
could possibly contribute to the lack of Spanish moss found in pine trees versus the amount found in hardwood trees at Lake

Biotic Factors In Hawaii
Plants are found everywhere on earth, up high on the ridge and down low in caves and caverns. The types of plants that live in these places depends on
many factors. These factors are separated into two different categories, the biotic factors and the abiotic factors. Some of the biotic factors include,
predation, competition, and habitat destruction. Plants with limited competition and large amounts of resources will be in a higher abundance than
plants with limited resources and higher competition rates will be confined to areas and either out competed or will be the dominant species. Certain
plants adapt to these factors and thrive and others don't do as well. Some of the abiotic factors include, sunlight, water, temperature, and wind. These ...
The ridge is known as an endangered dry ridge hike, for its endemic species and dry climate (Nelson 2003). The ridge trail starts on dole street near
the university of Hawaii at Manoa. From the campus, the ridge seems dry and grassy and it is expected as a dry leeward side ridge. This ridge is
also known for its brush fires during the hot seasons, the most recent being the fire in 2007. The fire left 50 acre of the ridge scorched and burned
to the ground (Siopack 2007). But, now in 2016 there has been an increasing amount of rain and the ridge has since begun to heal since the fire.
The beginning of the trail starts off dry with rocky soil and the dominant vegetation being the M. maximus that has a yellow brownish color. The
vegetation isn't completely covering the soil; it is mostly clumped together. As you continue to move up the trail the vegetation starts to get a little
greener and thicker. The M. maximus gets thicker, greener, and more dominant. The soil is still rocky and dry, but there are a few different
species such as the air plants and small shrubs. More of a change is seen further up the ridge once you are out of the tall grasses. The land is moister
and has a wide range of tree species and woody area. There was an abundance of Haole Koa trees, thorny bastards, all spice, and strawberry guava. It
was a large change from an open canopy of large

Earth, Our Earth : Steps To Save The Environment
Earth is our home. Our home needs to be protected and loved for it to survive for decades to come and for our future children. Taking the time to
learn and educate yourself about the environment and the home we live in is crucial not only for its survival but our own too. it is not only important
to realize how our daily lifes harms the environment but also that there are many steps we can take to save the environment as well. First step in doing
so, is learning what the environment is, what makes up the environment, what are we doing wrong and what can we do that is right to save our home.
The environment is made up by everything surrounding and affecting us daily. It is the air we breathe, the water that covers the earth's surface, the
plants and animals arounds, and much more. In the environment there biotic and abiotic factors that sometimes interact with one another. a biotic
component is any living thing in an ecosystem, such as animals, plants and microorganisms. Abiotic components are the non–living parts of an
ecosystem, such as temperature, sunlight, clouds, and the chemicals in the soil. Both biotic and abiotic factors interact in the ecosystem and if one
factor is chaged or removed, it can affect the entire ecosystem. Abiotic are specially important because they directly affect how organism such as
ourselfs survive. One example of the interaction between biotic and abiotic factors is with plants. The plant is a biotic factor and uses abiotic factors
such as sunlight and water to make food and survive.
Society has been affected by the environment and affected the environment we live in. while many things have been changing due to human ativity,
much as been preserved and protected by human activity.the interactions between humans and the environment are constantly changing. The way we
treat the earth and the earth treats us has changed over the years. These effects include decrease water quality, increased pollution and greenhouse
emissions, depletion of natural reousrces and contribution to climate change. Some of these effects can be easily linked to human activities whereas
others remain unclear. Water pollution is primarily the fault of humans and the excess input of nutrients into the

Caribbean Sea Abiotic Factors
The Caribbean Sea in located off the coast of North, Central, and South Americas. This sea spans about two million, seven hundred and fifty–three
thousand square kilometers. There are also many islands found in the midst of the Caribbean Sea. While these islands are a great place for a vacation,
the populations of people on the islands can affect life. Many different factors influence life in the Caribbean Sea. These factors are divided into two
categories; abiotic factors and biotic factors. These types of factors can influence biodiversity in a certain area. A change in a single population results
in a huge change in an ecosystem that was previously well–balanced and diverse. Populations change in size all as a result of these factors.
Abiotic factors, such as rainfall and temperature, are different from place to place. In the Caribbean, the abiotic factors vary from water current to water
depth, from the amount of sunlight to the oxygen levels. The Caribbean Sea is large and there are many measuring points throughout the sea, this
results in different conclusions for the same question. Now, that being said, the results recorded in this paper are strictly and average. The average
amount of precipitation in the Caribbean per year is as low as twenty–five centimeters in some parts to as high as nine hundred centimeters in other
parts, that just goes to show how big the Caribbean really is. That being said, the deepest measured part of the Caribbean sea can be found between

The Role Of Critical Thickness Subordinate Impacts Acting...
What is intriguing is the nearness of critical thickness subordinate impacts acting in a deferred way on the diverse conceptive parameters broke down.
The part of conceptive females, the proliferation file, and the regenerative rate were to a great extent dictated by the populace thickness the prior year.
The generation record and the regenerative rates were not affected by the precipitation design. The multiplication list speaks to the extent of
regenerative females and adolescents in the populace. Therefore, one conceivable reason for the non–huge relationship amongst precipitation and
multiplication record might be the expansion of grown–up movement after stormy winters (Lima and Jaksic unpublished work). Then again, the
regenerative rate is a gauge of the quantity of adolescents delivered by a female amid the reproducing season, and includes the litter size, litter number
and the survival rates of the posterity. Consequently, our outcomes propose that precipitation does not impact these parameters. This is a fascinating
result, in light of the fact that an expansion in the quantity of litters created by females after abnormally stormy winters has been hypothesized as one
of the instruments activating populace episodes of this species. A few studies have discovered abundant proof of social cooperation's in microtine
rodents, including spatial conduct, territoriality and forceful experiences. In general, these components appear to create quick thickness subordinate

Chapter 1 Introduction
1.1Component Based Software Engineering
Introduction
Component–Based Software Engineering (CBSE) means the development of software by using pre–developed software components. It may contain
external as well as in–house built components. Component–based development approach develops the software systems by choosing appropriate
components and then integrating them by using a well–defined architecture. Component based software engineering (CBSE) has become a modern
approach of software development that provides an optimal, efficient, economic and quick software development as per user requirements.
The Need of Component Based Software Engineering
Modern software systems have become more and more large scale and complex which results in higher cost of building the systems, low productivity,
and degraded system–quality. Thus need of developing a good, economical software development strategy arose.CBSE helps to deal with complexity by
following a divide and conquer approach, modularising large softwares systems into smaller, reusable units called components. CBSE helps in
decreasing the development cost of the systems, the time it takes to deliver to the customer, enhance the maintenance of the software and dependability
on the system.
Component–Based Software Engineering Process
The Component–Based Software Engineering Process involves
a)Recognition of candidate components
b)Qualification of the interface of each component

Four Characteristics Essay Comparison Of Four Ecosystems
Comparison of Four Ecosystem Essay Assignment An ecosystem is the "relationship between the biotic and abiotic components. Biotic components are
composed of all living things in contrast, abiotic components are composed of the non–living parts of an environment." (Ms. Blackshaw) This essay is
focused on the abiotic factors that influence an ecosystem. They are many abiotic factors affecting an ecosystem such as temperature, water, wind,
sunlight, rocks, soil, and oxygen. However, the three abiotic factors that affect a parking lot, field, meadow, and forest the greatest are wind, rock and
water. Wind is defined as the movement of the air. Even though, Wind is an abiotic factor it is still vital for various ecosystems. In parking lots, wind
is non–prominent due to the lack of trees compared to the forest, where it is chilly and windy. Some biotic factors that were recorded in the parking
lot were, grass, tress, and dandelions. Dandelions are important for bees and other organisms that consume nectar. Without wind, the dandelion
blossoms would not be able to blow away creating more dandelions for bees and other insects to consume. This gives the organisms less nectar and
it may cause death because the lack of resources for them to consume in that area. Fields produce more wind currents compared to parking lots
because its an open space, with more trees. Since there are not a lot of interferences with the fields, wind picks up grass pollens and spreads it
throughout the fields making the fields richer and healthier. This allows the primary consumers to eat the grass and be healthy. Causing the entire
food chain to be healthy. Meadows compared to fields, have a bit more wind due to the trees and bushes that compose the ecosystem. The winds help
for cooling birds and insects. Wind also affects plants throughout their growth. Slight winds help the plants grow sturdier, so other consumers can
benefit from it. Winds in forests are very high due to the number of trees. Due to more wind, it helps animals such as birds to fly without much effort
and the same with butterfly's. Without wind in forests animals that fly tend to struggle a lot because it does not have wind support. Rock or stone is a
natural substance.

Advantages Of Principle Component Analysis
3.4. Principle Component Analysis (PCA)
Principle component analysis, also referred to as eigenvector transformation, Hotelling transformation and Karhunen Loeve transformation in remote
sensing, is a multivariate technique [66] that is used to decrease dataset dimensionality. In this technique, the original remote sensing dataset, which is a
correlated variable, is distorted into a simpler dataset for analysis. This permits the dataset to be uncorrelated variables representing the most significant
information from the novel [21]. The computation of the variance covariance matrix (C) of multiband images is expressed as: Where M and X are the
multiband image mean and individual pixel value vectors respectively, and n is the number of pixels.
In change detection, there are two ways to relate PCA. The first method is counting two image dates to a single file, and the second methods is
subtracting the second image date from the corresponding image of the first date after performing PCA individually. The disadvantages of PCA can...
For example, Baronti, Carla [39] concerned PCA to examine the changes occurring in multi–temporal polarimetric synthetic aperture radar (SAR)
images. They used association instead of a covariance matrix in the transformation to condense gain variations that are introduced by the imaging
system and that provide weight to each polarization. In another example, Liu, Nishiyama [49] evaluated four techniques, including image differencing,
image ratioing, image regression and PCA, from a mathematical perspective. They distinguished that standardized PCA achieved the greatest
performance for change detection. Standardized PCA is better than unstandardized PCA for change detection because, if the images subjected to PCA
are not calculated in the same scale, the correlation matrix normalizes the data onto the same scale

Principle Component Analysis ( Pca )
PCA model Principle component analysis (PCA) is often used to reduce the dimensionality of a data set, and the reduced data can then explain most
of the variance within the original data (Guo, Wang & Louie, 2004). The main function of the PCA is to convert a number of interrelated variables
into a smaller set of independent variables. The new independent variables which are called principal components (PCs). They are the linear
combinations of the original variables (Jackson & J.E., 2005). The PCA model can be expressed as (Miller et al., 2002): Z_ik=в€‘_(j=1)^pв
–’гЂ–G_ij
H_jk гЂ— i=1,2,...,m;k=1,2,...,n (1) Where: G_ij= the correlation of compound i with factor j H_jk= the relative impact of jth factor for the total
contaminant of the kth... Show more content on Helpwriting.net ...
Standardization of the original data before the PCA can help us better understand how the variables influence the analysis (Thurston & Spengler,
1985). Before applying the standardized data to the PCA, the outliers should be excluded. A sensitivity analysis should be done to determine the
outliers which should be removed. The suspected outliers should be removed from the data set one at a time until the PCA reaches a stable result
and the further exclusion of the samples has very little effect on the PCA results (Swietlicki et al., 1996). Outputs The output of the PCA based on
Matlab includes the following: "coeff" file, "score" file, "latent" file, "tsquared" file, and the "explained" file. The "coeff" file is a matrix of the
principal component coefficients, or we can call them loadings. If the input matrix is n–by–p, then the coefficient matrix should be p–by–p. The
columns of the coefficient matrix represent the principal components, and the columns are placed in descending order according to the component
variance. The "score" file gives us a matrix of the principal component score which represents the input matrix in the new principal component space.
The score file represents the projection of the

A Brief Note On The Temperate Deciduous Forest Biome
Alexis Apicella
Chapter 5.
1) I live in the Temperate Deciduous Forest Biome and within this biome the temperature and precipitation are the most important determinants. There
are distinct seasons where the summers are warmer than in the winters. Also in the fall the leaves will fall off of the trees and in the following spring
they will appear again. These factors have changed over the past 100 years due to global warming. The weather within seasons have changed resulting
in more frequent hot days and fewer cool days.
2) We cannot protect people from a natural disturbance such as a fire, because it is a natural part of an ecosystem and are bound to happen. We cannot
control flooding, windstorms, or earthquakes, which are also natural disturbances, therefore we prevent fires where houses were built in the path.
Chapter 6.
3) There are more disadvantages of living longer or reproducing more quickly then there are advantages. In order for a species to survive they must
have access to food and water. As apopulation is growing at a fast rate they are using up their environment much quicker then before. The
environment has no time to replenish itself since every moment animals are looking to feed. Each environment has a limited capacity of they are able
to offer a species and once that capacity is met, shortages of food and resources eventually lead to a population crash.
4) Abiotic factors are caused by nonliving components of the environment and are density independent

Gun, Hunting, And Personal Defense
Putting rounds down range every time you pull the trigger on your firearm is very important, whether for target shooting, hunting, or personal defense.
Equally important to putting rounds down range is the proper maintenance of your firearm. There are many types of firearms in today's world with
some that are more complicated than others in their operation and maintenance. One of the easier firearms to maintain is the Armalite Rifle, Model 15,
otherwise known as the AR–15. The basic disassembly, or field striping, of the AR–15, is universal regardless of who the manufacture is or how the gas
system is set up. You will only need a clear work surface, a beach towel or similar item, and a number 2 punch to complete the disassembly process....
Place your towel flat on your work surface before proceeding (this is to help prevent oil, grease, powder residue, and your firearm from damaging
the work surface). The first step in disassembly after making the weapon clear and safe is to separate the upper receiver group from the lower
receiver group. Locate the takedown pin, which is located just above the safety, and the pivot pin, which is located at the front of the lower
receiver. With your number 2 punch depress the takedown pin from the left side. You should feel a noticeable click when the takedown pin
overcomes the force of the takedown pin detent. Repeat for the pivot pin, being careful not to push the pin all the way through the receiver. The
takedown pin and pivot pins should now be partially extended on the right side of the lower receiver. Lay the firearm on its left side so it lies flat
on your work surface. Grasp the takedown pin from the right side and pull till it fully extends out the right side of the receiver. Again, you should
feel a noticeable click when the detent pin engages the takedown pin at the fully extended position. Now repeat by grasping and pulling the pivot
pin till it fully extends out the right side of the receiver. Next, while holding the lower receiver group, grasp the upper receiver group and slide it
clear of the lower receiver group. At this point the lower receiver group disassembly is complete, so sit it to one side

Human Distribution Patterns Of Acacia Saligna
Abstract
Distribution patterns of Acacia saligna are quite diverse in South Africa especially taking under consideration that they do not have immediate threats
that inhibit their spread. However, this species occurs in very different environmental gradients, as it can occur from a wet habitat/area to a bare rock
surface that is a very dry habitat. Due to such observations for the distribution of this species a question is imposed in this paper as to how do traits
vary along environmental gradients? Two phenotypic traits/characteristics are investigated, Specific Leaf Area (SLA) and wood–density. SLA was
calculated by adding the total sum of all the leaf area per individual and dividing that with the total sum of all the leaf dry mass per individual. SLA =
Total leaf area/ Dry leaf mass, SLA unit g/cmВІ. The highest value for SLA is at the dry site, intermediate in wet site and lowest in the ultra–dry site.
The wood–density for branch and stem samples was calculated using the latest dry mass value/ volume. Wood–density unit measure is g/cmВі. The
stem wood–density was highest at the ultra–dry site, followed by wet site and then the dry site. Branch wood–density was highest at the dry site,
intermediate at ultra–dry site and lowest at the wet site.
Introduction
Acacia saligna is a small tree endemic to the Swan Coastal plain in the Mediterranean climate region of south–west Australia and is widely naturalized

Rocky Shore Ecosystems– Point Cartwright

Due Date: 03/09/2010
Introduction:
On the 23rd of August, the three biology classes or grade 11 at Redlands College visited the rocky shore ecosystems at Point Cartwright in Queensland.
Two different types of rocky shoreecosystem were examined, the rock pool area, and the boulder area. We first examined areas within the rock pool
area. The rock pool area has several specific features which set it apart from other rocky shore ecosystems, including its geological makeup and
position. It is made up of a flat platform of rock pockmarked with numerous rock pools; indents in the rocks which are filled with water and contain ...
Sea anemones feed from the surrounding water by catching small micro–organisms in their tentacles. For this reason, anemones need constant water to
survive which is why none were observed in the boulder area as an area with constant water cannot be guaranteed. Sand is another factor which is
present in the boulder area, but not in the rock pools. Sea cucumbers were thriving closer to the low tide mark in the boulder area, yet none were
observed in the rock pool area. Sea cucumbers are almost always found laying spread out across the sand, with their feeding tubes out, browsing
along the sand bed. This is the feeding habit of the sea cucumber and it would not be able to carry out this habit without the presence of sand. It is
shown time and time again by the presence and habits of specific organisms in each area that the abiotic factors of each area affect the ability for an
organism to survive in that system.

Executive Summary
Recent quality related issues have put Samsung Electronics, one of the world's largest technology companies at risk. These quality concerns, spiked
through recent recalls and external complaints, have generated a flow of bad news coming to the desk of quality director Kevin Sarni. The issues most
commonly found within the complaints related to display issues, customer service support, faulty electric components, audio, and safety. Of the main
issues, display and customer service support appeared to be the most detrimental. Once the patterns and themes became visible, Samsung and its quality
director Kevin Sarni were challenged with immediately identifying root causes. This was ... Show more content on Helpwriting.net ...
Assuming that many of the display issues are caused by faulty components, such as the main board, it is important to identify where in the process
these faulty components are coming from whether it be internal manufacturing processes or suppliers. Since suppliers happen to be at the beginning of
the supply chain it would be necessary to begin there. Sarni, along with cross–functional teams from Samsung must immediately schedule a visit to
their main suppliers of components such as the main board. Once the visits are scheduled, Sarni and the cross–functional teams will conduct extensive
audits of the supplier's processes and systems. The audits will consist of detailed examinations of the supplier's equipment, process capability, facilities,
and personnel. Each supplier they visit, Sarni along with another manager, will be responsible for grading each supplier. The grading metrics should
consist of defects per day, damage, flexibility, responsiveness, and communication. Grades will be recorded on a supplier scorecard and then
electronically documented upon return to Samsung's office. Dependent on the findings, Sarni may be faced with choosing another supplier, that is, one
who is consistently able to meet design specifications. Eventually, once a quality supplier is developed within Samsung's network of partners, Sarni
must direct significant effort in monitoring their performance. To monitor the supplier's performance overtime, Sarni

Hypotheses
Water quality parameters such as pH, dissolved oxygen, seston, water temperature etc. are important variables in the abundance and diversity of benthic
macroinvertebrates of the Old Chelsea stream. Therefore, it can be hypothesized that pH and dissolved oxygen have a direct correlation on biotic factors
within the stream. Furthermore, due to the surface water velocity variations of the stream, it is hypothesized that water pH and dissolved oxygen
interreach variability is statistically significant.
Results
Note that for figures 1 and 2, the ... Show more content on Helpwriting.net ...
In figure 2, we observe that dissolved oxygen levels are higher in site 2 compared to site 1 and that variations within the same site are rather small.
Lastly, both figure 1 and figure 2 show slightly higher elevations of both pH and dissolved oxygen at the 3rd location of sampling. In figure 3, we
observe a significant correlation between pH and Simpson's Diversity Index where it can be noted that the higher the level of pH, the higher the
diversity index. In figure 4, we observe an unsupported correlation between pH and total taxa. Henceforth, total taxa does not depend on pH levels.
In figure 5, an unsupported correlation between is observed between dissolved oxygen and Simpson's Diversity Index. In figure 6, an unsupported
correlation is observed between dissolved oxygen and total taxa. As in figure 4, it can be concluded from these observations that total taxa does not
depend on dissolved oxygen levels in the water. In figure 7, it is observed that the percent relative abundance of taxa at site 1 does not share a
particular link with the percent relative abundance of taxa at site 2. Furthermore, different taxa are shown to be dominant for both sites. Ephemeroptera
and Odonata are the only taxa shared by both sites according to this figure. In table 1, the most prominent statistical conclusion was failure to reject the
null hypothesis, that the variability of abiotic factors (pH and dissolved oxygen)

Environment And Human Environment
Ecosystems is the dynamic complex of plant, animal and micro–organism communities and their non–living environment that work together to form a
functional unit and they are constantly changing due to the fluctuating equilibrium from natural stress and human action which has had adversarial
impacts on ecosystems. This is evident in Minnamurra rainforest as human induced modifications and environmental stresses had resulted in a
vulnerable ecosystem. Furthermore, the removal of factors that contribute to the vulnerability of an ecosystem is important as it affect the functioning
of the ecosystem as processes are accelerated, biodiversity is decreased which greatly affects humans. Despite the negative effects caused by humans,
they have discovered that ecosystems are susceptible from harm caused by natural environmental factors or human impacts and realised the importance
of protecting and managing ecosystems therefore have implemented management strategies that are supposed to prevent further detriment and as a
consequence may induce resiliency.
Within Minnamurra rainforest all biophysical components rely on each other, for example changes to the lithosphere (gaseous elements surrounding
the earth), can cause stress to the flora and fauna within the ecosystem and impact other abiotic factors. Human interaction has also caused many
detrimental impacts on the ecosystem through changes in lithospheric processes. For instance littering can bring unwanted diseases that can affect

Principal Components Analysis ( Pca ) Versus Principal...
Principal Components Analysis (PCA) versus Principal Axes Factors (PAF) and Other Extraction Methods
Broadly, conducting factor analysis (FA) allows a researcher to analyze or interpret his or her data (e.g., measured variables) by reducing those
variables into factors or components that underlie the structure or explain the greatest amount of variance in the data (Thompson, 2004). Thompson
(2004) also tells us that FA may be used for many purposes, the most common of which is to uncover a relationship between variables, to develop
"theory regarding the nature of constructs" (p. 5), or to evaluate the validity of observed scores. To accomplish this analysis, the researcher uses
statistical software, such as the Statistical Package for ... Show more content on Helpwriting.net ...
The present paper describes the most common factor extraction methodologies and highlights differences, similarities, and important considerations
when conducting a factor analysis.
Terminology of Consequence
Before continuing, some basic terminology used in discussion of factor analysis and factor analytic methods should be clarified. Communality
coefficients (h2), according to Thompson (2004), reveal "...how much of the variance of a given measured variable was useful in delineating the factors
as a set" (p. 20). Alternately, communality coefficients represent the proportion of that variable's variance that is explained by the underlying factor.
Additionally, the communality coefficient can be thought of as a lower–bound estimate of a score's reliability (Thompson, 2004).
Sources of error and their effects must be understood as well. Sampling error is error unique to each sample drawn or selected; so, the sampling error
in two different samples are each different

The story Green Blazer brings order with representation of the foundation with build up the presentation and top of the story. The story has woven plot,
the author has woven together every components and character to build up a story. In the story there is just a single peak zone, which demonstrates the
falling and ascending of the activities. We can see that the story starts with the outline of the foundation, which incorporates the foundation of Raju, the
place they are situated at, his family, his general public and not to overlook the foundation of the green overcoat. In story the author demonstrates the
way of life of towns, and the city circumstance. At the point when the story builds up the stories turn out to be more confounded and the argument
emerges gradually. The author gradually shows the circumstance of the Raju, the motivation behind why Raju pick the calling, it is providing in the

Components Of Most Influential Components
We identified the affected components of most influential components in both type of perturbations. We combined all the four environmental
conditions to construct the network of the most influential components with downstream targets. On these networks we mapped druggable proteins
and cancer associated genes. Under inactivating perturbations, we obtained the network of PI3K, EGFR, PP2A, GRK and CaM (Figure 7A). Under
activating perturbations, we obtained the network of influential components i.e. EGFR, IL1_TNFR, ERK, SHP2, RKIP, Ras, Gbg_i, Fak, Integrins, and
PP2A (Figure 7B).
The ranking of these components based on number of affected components is shown in Table 4. We observed that the EGFR is affecting most number
of components under activating as well as inactivating perturbations. Interestingly, EGFR is a validated drug target for cancer [34].
The other influential components such as PI3K, ERK, and Ras have been previously explored in multiple cancer types. However, the influential
components consist of the most important drug candidates that block cell proliferation in cancer cells. Some of these components have been associated
with the drug resistance. For example, in non–small cell lung cancer, EGFR showed mutation in its kinase domain, Epithelial–mesenchymal transition,
and mechanisms to develop resistance to gefitinib [35]. In colorectal, and head and neck cancers KRAS mutation, EGFR–S492R mutation, and
increased ErBb signaling are responsible for resistance

The Development of an Artificial Life based Software...
The behavior of a solution or a service can be analyzed by taking into account the interaction between the components of the software. These
interactions can be analyzed by developing a framework based on Artificial Life. This calls for the development of an Artificial Life based Software
Ecosystem model. This paper proposes a framework using Artificial Life in the Software Ecosystem. In order to find the gaps in the existing
methodologies, extensive literature review has been carried out. It was found that the interest in the topic has been on the increase and the advent of
professional Ecosystems has helped popularizing the phenomenon. However, the present framework do not use the data related to evolution of the
Software for later stages. The proposed methodology would pave way of Artificial Life in Software Ecosystem.

components. A SE considers the concept of evolution of the software in the same way as the evolution of a natural ecosystem. It has been pointed out
by many researchers that considering the system's evolution would lead to a better and comprehensive analysis of the software which would ultimately
help in management and development of new versions. The point can be understood by the following analogy. If we consider that evolution of a human
being, then what humans have done in order to achieve, what they have been able to

A tidal salt marsh is a community of plants and animals that thrive in wet saline conditions (ADBC, 2010), which rely on the tides to bring
nutrients, such as oxygen, nitrogen, and phosphorous. As the tide leaves the wetlands, pools are exposed which shorebirds can feed on larvae
without competition from fish that was impossible during the time period of water diversion and dam construction. The land became baron; an area
of waste land, until 1967, when the water originally diverted for irrigation of fields, was redirected to the lowland area. In 2006, a tidal inlet was
successfully opened after 107 years, allowing the tide to flow to various parts of the wetlands which had previously been closed off (ADBC, 2010).
During the process of Bolsa Chica environmental change, much has been learned about ecosystem destruction and restoration. Wetland areas are as
Wright states "among the most productive ecosystems on earth, rich in breeding grounds for many species of fish, shellfish, and waterfowl" (2008).

Abstract Duckweed is a small aquatic plant that is able to grow rapidly, making it the ideal specimen for our experiment. It is hypothesized that
altering the amount of light received by duckweed will alter its photosynthetic rate. It is predicted that a lower light intensity will lower the rate of
growth in duckweed. Two treatment groups were covered with a screen in order to reduce light intensity. Both groups were kept under a controlled
light source for fourteen days and plant counts were taken at regular intervals. The ravg for the experimental group was 0.1613 and the ravg for the
control group was 0.2047. The results indicated that our predictions were correct; duckweed that received less light exhibited a lower rate of... Show

The average population on day 13 for the treatment group was 172.5 individuals and 307 individuals for the control group. Our results show that
the group which received less light had a lower population count and exhibited a lower overall per capita growth rate. The average population
count for duckweed in the treatment groups was lower than that in the control groups for each day data was recorded (Table 1). By day fourteen,
the average population size of the control group reached 307 individuals, nearly twice that of the treatment group (Table 1). Table I: Population

Cepaea Nemoralistic Lab Report
In this study, we designed and examined the effects of different degrees of soil moisture levels on the distance travelled of Cepaea nemoralis. Our
experiment showed that the average distance travelled of Cepaea nemoralis was higher in moister levels of soil. This was the case in both Trials 1
and 2 and statistical analysis showed that both Trials were statistically significant (See Figures 1 and 2). Through various research and previous
observations, our prediction was that the Cepaea nemoralis would move a longer distance in moister levels of soil. Higher levels of soil moisture were
expected to cause more movement because the mucus produced by the glands helps them move more efficiently, without hurting themselves (Why Do

One of these snails was Cepaea vindobonenis, which is very similar to Cepaea nemoralis. They measured the occurrence of snails in transects in 9
different locations. The soil moisture varied from 24% to 42% and results were similar to ours as more snails were found in moister areas
(HettenbergerovГЎ et al. 31–42). Our results were similar to the articles, as in both cases, activity increased in moister soil. However, there could be a
discrepancy because the soil moisture levels used were much higher in this study than ours (13% and 27%). However, even in this case, there were
more snails in the moister areas, similar to our experiment. The consistency of our results with this study strengthens our findings as the results are

Efficient and Sustainable Ecosystems
Ecosystem Report:
Introduction:
Ecosystems are everywhere. Any place that contains living and non–living organisms (biotic and abiotic), that share the same space are a community,
this is called an ecosystem. An ecosystem can occupy a large space in the environment, or a very small space. To make up anecosystem, there must be
an interrelationship between the abiotic and biotic components in the ecosystem; for example, there must be a series of food–chains in order for the
different species to survive in that particular ecosystem. Another definition of an ecosystem is:
'They consist of all the organisms in a community, their biotic and abiotic environments, and exchanges within and between each of these' (Knox et al.
2010, p. 128).
The purpose of this investigation is to thoroughly study an ecosystem, to expand the knowledge of many who wish to further understand the
environment and its components. By completing this investigation it allows for people to understand the importance and needs for having and
maintaining healthy ecosystems. For example, 'Ecosystems provide food both in their natural state...in the form of managed landscapes' (International
Water Management Institute 2011, p. 11). The investigations of ecosystems are vital in today's society because people can learn how to better treat and
take care of them so they are more efficient and sustainable.

ABSTRACT
Abiotic and biotic factors are extremely important factors for our environment. The presence of these factors could provide for a peaceful and healthy
environment and the disappearance of these factors could wreak havoc on an environment. Abiotic factors focus more on the physical aspects of an
environment and biotic focuses more on biological.
MAIN BODY
What are important abiotic and biotic factors affecting organisms that are considered in Natural Resources Production decisions?
Abiotic refers to something physical rather than biological. Abiotic factors can determine which species of organisms will survive in any given
environment. This factor is important because they affect how organisms survive. The abiotic factor can be placed into categories of meteorology, soil,
air pollution, micro–topographic features, water availability, and water quality. Chemical and geological factors, such as rocks and minerals, and
physical factors, such as temperature, weather, and lay of the land, are also referred to as abiotic components.
Biotic factors are the living parts of an ecosystem, such as the animals, plants, and microorganisms. A factor created by a living thing or any living

Investigating The Charging And Discharging Abilities Of A...
The objective of the experiment was to measure the charging and discharging abilities of a resistor capacitor circuit. In a RC circuit the voltage is an
asymptomatic function of the charging time. If a battery were connected in series in a circuit with a resistor, there would be a constant current. In
contrast, if the battery were connected with a capacitor in series, the current would be time–varying, decaying to zero as the capacitor charges up. The
results of the experiments verified the properties of the RC Circuits, confirming that voltage is a function of the product of resistance and capacitance.
The experiment produced results that agreed with expectations confirming the electrical theory of RC circuits.
Sources of error ... Show more content on Helpwriting.net ...
Capacitors are considered nonlinear devices because their charging and discharging rate depends on the charge already there on the capacitor. The
higher the charge on the plates of the capacitor, the slower its charging rate. This is because the slow buildup of electric charge poses resistance to the
addition of extra charge as voltage starts to build across the plates. As a result, the flow of current gets smaller. In contrast, while discharging, the higher
the charge on the plates, the faster it discharges. On the application of a voltage source to a circuit, the capacitor attempts to reach the full voltage
asymptotically, even though it never reaches the full voltage. The mathematical formula that represents the voltage across the capacitor is:
V(t) = V0(1–et/RC)
For a charged capacitor, the mathematical formula that represents the voltage across the capacitor as it is discharging:
V(t) = V0(et/RC)
Where:
RC is the time constant Ж¬ of the circuit;
V0 is the potential difference in volts (V) of the voltage source;
R is the resistance in ohms (О©);
C is the capacitance in the circuit in farads (F); and
T is the time measured in seconds (s).
After one time constant, the voltage is (e–1) x (V). It takes almost 3 times RC for a capacitor to get charged to 95% of the voltage. Ж¬ (seconds) = R
(ohms) x C (farads)
From Ohm's Law:
R = V/I;

Capacitance = Q/V (charge stored per voltage applied); and
I = Q/t (amount of charge flowing per time).
As such:
RC = R x
