5 Sex Advice for Women tips
1. We Respond to Praise
It's believed that men are so consumed by our libido that we have no self-consciousness surrounding sex. But men are no different from women when it comes to compliments as catalysts for sexual confidence. This praise can be delivered before reaching the bedroom (give us the once-over and tell us how buff we look), and after (give us the once-over and tell us how buff we look naked). Along those lines, men worry about the size of their guts (and other measurable organs), their hair (or lack thereof) and other attributes. Try to be extra affirming about those sensitivities.
2. We Fear Intimacy…
…but not for the reason you think! Studies have shown that boys are more affectionate, even more expressive, than girls until they reach school age. At that time, social repression begins—of words, thoughts, feelings—and our desire for human connection goes underground. So taboo is this desire for intimacy that its possibility can terrify men—not because it's smothering, but because we realize how desperate we are for it. What's a woman to do? First, understand that your guy's hasty retreat post-sex may be about his own shock at how much he craves a connection with you (and how much he's denied it in life). Then, retreat a little yourself. This gives him time to see that his boyhood habits are, in fact, perfectly manly.
3. We Appreciate Sex for Sex's Sake
Having said that about intimacy, sometimes a little "throw-me-down sex" is the right medicine. According to Joe Kort, PhD, a psychotherapist and sexologist, "Men want their wives to enjoy raw sex, not just endure it or take it personally. For men, it's not about dominating a woman, but ravishing her." On occasion, try letting him ravish you.
4. We Are Not Just Our…
The penis gets all the press, but men have "many erogenous zones," says psychologist Melodie Schaefer, PsyD. "Men tend not to correct women because they're afraid women will shut down and not touch them at all. But there are many places a woman should touch." Like the chest, the inner thighs and face. Two other key areas: Gently gripping a man's testicles can be a real turn-on, as it blends control with release. Also, stimulating the perineum, the area between the scrotum and anus, will heighten pleasure during oral sex.
5. We Like It When You Talk
Talking during sex stimulates more than our ears. What kind of talk? Dirty, praising and instructive are great starts. As amusing as it may sound, a woman's words can make a guy feel as potent and virile as a Roman gladiator, even if he's a suburban banker.

GENERATIONS OF COMPUTED TOMOGRAPHY
There are 7 generations of CT scanners that have advanced over time to provide faster acquisition times, better spatial resolution, and shorter reconstruction times. The document describes each generation's key features and advantages/disadvantages. First generation used a pencil beam and translate-rotate motion. Later generations introduced fan beams, complete rotation, ring detectors, and dual x-ray sources to improve imaging capabilities while reducing motion artifacts and scan times. The latest generations aim to differentiate tissue composition using dual-energy techniques.
Basics of CT
Computed tomography (CT) uses X-rays to produce cross-sectional images of the body. A CT scan involves the patient lying on a table that slides into a circular opening containing an X-ray tube that rotates around the patient, emitting an X-ray beam. Detectors on the opposite side of the circle detect the beam after it passes through the body and is absorbed to varying degrees by different tissues. A computer analyzes the data from multiple angles to construct a three-dimensional image of the scanned area. Modern CT scanners can obtain multiple slices simultaneously using multiple detector rows for faster, more detailed imaging.
Determination of Cholesterol Level in Human Serum
Clinical chemistry uses chemical processes to measure levels of chemical components in the blood. It is very useful for the early diagnostic of disease and for monitoring organ function. The most common specimens used in clinical chemistry are blood and urine. Table 1 shows the common blood tests and measurable items using UV/Vis spectrophotometers.In this application note, the cholesterol level in human serum was determined by the enzymatic method using the LAMBDA™ 465 UV/Vis Spectrophotometer and UV Lab™ software.

Interaction of xrays and gamma rays with matter ii
The document discusses four main mechanisms by which photons interact with matter: coherent scattering, photoelectric effect, Compton scattering, and pair production. It provides details on each mechanism, noting that the photoelectric effect dominates at low energies, pair production at very high energies above 1 MeV, and Compton scattering is predominant at medium energies. It also discusses absorption and transmission of photons in materials, how attenuation coefficients vary with photon energy and material properties like atomic number, and the spatial distribution of secondary radiation produced.
Radioactive application in medical
Radioactivity occurs when an element has an unstable nucleus that decays by emitting radiation such as alpha, beta, or gamma rays. Radioactive isotopes are used widely in medicine for diagnosis and treatment through applications like medical imaging and radiation therapy. Some common medical isotopes used are iodine-131 for thyroid imaging and treatment, and cobalt-60 and iridium-192 which are supplied in wire form for internal radiotherapy of cancers. Radioactivity was discovered accidentally by Henri Becquerel and further research was conducted by scientists like Marie and Pierre Curie to isolate other radioactive elements.
Dexa and its aplication
A DEXA scan uses dual energy x-ray absorption to measure bone mineral density and assess osteoporosis risk. It involves passing two low-dose x-ray beams through the body to create a 2D image and calculate the density in specific areas like the spine or hip. DEXA is the most effective technique for measuring bone mineral density and uses T-scores and Z-scores to evaluate results against young adults and age-matched peers respectively.
Liver, biliary system, pancreas and spleen
This document discusses the anatomy of the liver, pancreas, and portal system. It begins with the embryological development of these organs, then describes the anatomy and blood supply of the liver in detail. It also discusses the gallbladder, biliary tree, pancreas, and their related structures and variations. Key functions of the liver are outlined. The document provides a thorough overview of the anatomy relevant to upper gastrointestinal and hepatobiliary surgery.
Interaction of radiation with matter
The document discusses various types of interactions that occur when radiation interacts with matter, focusing on electromagnetic radiation and particulate radiation. It describes the photoelectric effect, Compton scattering, and pair production in detail. The key points are:
1) The photoelectric effect occurs when a photon transfers all of its energy to an electron, ejecting it from an atom. The probability of the photoelectric effect increases with lower photon energy and higher atomic number.
2) Compton scattering occurs when a photon collides with and scatters off an electron. It dominates between 50keV and 24MeV.
3) Pair production occurs when a photon converts into an electron-positron pair, and dominates above 24MeV.
Calcium biochemical role, rda and deficiency
Mineral introduction, General functions, Classification, Macroelement of calcium , Ca- introduction, Biochemical role of calcium, recommended dietary allowance of calcium, dietary sources of calcium, Deficiency disease of calcium.
X ray production & emission
The document discusses x-ray production in an x-ray tube. Electrons are emitted from a cathode and accelerated towards an anode. When electrons interact with the anode target, most of their energy is released as heat but 1% is released as two types of x-rays: characteristic x-rays of specific energies that are dependent on the target material, and bremsstrahlung x-rays that form a continuous spectrum. The x-ray emission spectrum contains peaks from characteristic x-rays and a curve from bremsstrahlung x-rays, and factors like voltage, current, filtration affect the spectrum's intensity and average energy.
Bone marrow density (BMD)
Bone densitometry, also called a DEXA scan, uses low-dose X-rays to measure bone mineral density and assess osteoporosis risk. It is most often performed on the lower spine and hips. A DEXA scan provides a T-score comparing the patient's bone density to that of a young adult, and a Z-score comparing it to others of the same age, gender, and body size. Osteopenia and osteoporosis are diagnosed based on negative T-scores below -1 and -2.5, respectively. DEXA scanning is a quick, low-radiation procedure used to diagnose bone density issues and monitor treatment effectiveness.
10 Best Sex Tips for Men
1. It’s safer at the shallow end. What I mean by this is that, evidence suggests, the outer third of the vagina is the most sensitive, so deep thrusting isn’t essential - at least not for her! Instead, try ‘dipping’ the tip of your member in and out of her vagina.
2. There are more than two erogenous zones. Yes the breasts and pubic area are obvious hot-spots but they get a lot hotter when stimulated in conjunction with other areas. Try kissing and gently stroking her neck, back, stomach and inner thighs.
3. Women are slow burners. For women, good sex takes time. Women are also more emotional lovers. So dedicating 10-15 minutes prior to sex, cuddling, kissing and holding your partner will be infinitely more successful at getting her aroused than spending a frustrating 5 minutes rubbing an unresponsive clitoris.
4. Tell her how great she looks. And mean it. On the whole, women don’t love to be naked. The second her clothes come off she feels vulnerable and sensitive. When she undresses, tell her what you love about her body. And if she tries to turn the lights off, turn them back on to show her she has nothing to be embarrassed about.
Urinarytractlecture2 120223144704-phpapp01
This document discusses radiology of the urinary tract system and disorders. It describes how different imaging modalities like CT, ultrasound, and IVU can be used to identify urinary tract calculi, nephrocalcinosis, and obstruction at different levels of the urinary tract. Causes of obstruction include calculi, tumors, strictures, congenital issues, and extrinsic compression that are best evaluated using CT, ultrasound, or IVU depending on the level and nature of obstruction.
Interaction of radiation with matter
1) The document discusses the interaction of radiation with matter, including the different types of radiation and their properties. It describes electromagnetic radiation and the electromagnetic spectrum.
2) The main interactions that occur between radiation and matter are photoelectric effect, Compton scattering, and pair production. The photoelectric effect involves the ejection of an electron from an atom when a photon transfers all its energy. Compton scattering is the scattering of photons by loosely bound electrons, resulting in energy transfer. Pair production occurs when a photon converts into an electron-positron pair in the vicinity of a nucleus.
3) The dominant interaction depends on the photon energy - photoelectric effect dominates at low energies, Compton scattering in the soft

Renal Anatomy - applied aspects
The kidneys are paired organs located retroperitoneally on either side of the vertebral column. Each kidney is bean-shaped and surrounded by three layers - a fibrous capsule, perirenal fat, and renal fascia. The kidneys receive their blood supply from the renal arteries and drain into the renal veins. They have an extensive arterial supply that branches into segments and interlobar arteries within renal columns. The kidneys also have a complex calyceal system that drains urine into the renal pelvis and ureters. Percutaneous access for procedures must consider the location of calyces and vascular anatomy to avoid complications.

CT urography
CT urography provides a comprehensive non-invasive evaluation of the urinary tract. It is performed as a multiphase exam, including an unenhanced phase followed by corticomedullary, nephrographic and excretory phases after intravenous contrast administration. The nephrographic phase provides the highest sensitivity for detecting renal masses and abnormalities. Various dose reduction techniques can be used, including lower dose protocols, split-bolus contrast injection, dual-energy CT, and iterative reconstruction. These allow radiation doses to be reduced by up to 80% compared to traditional triple-phase CT urography exams.
Spectral matchin
This document discusses spectral matching in x-ray films. It explains that the phosphor in radiographic screens must emit light within the sensitivity range of the film emulsion used. Calcium tungstate screens are used with blue-sensitive films, while rare earth screens require green-sensitive films. Crossover is reduced by using screens that emit short wavelength light and by including a dye layer in the film base to absorb crossover light.
