Pendrin is a Cl-/HCO3- exchanger expressed in the apical regions of renal intercalated cells. Following pendrin gene ablation, blood pressure falls, in part, from reduced renal NaCl absorption. We asked if pendrin is expressed in vascular tissue and if the lower blood pressure observed in pendrin null mice is accompanied by reduced vascular reactivity. Thus, the contractile responses to KCl and phenylephrine (PE) were examined in isometrically mounted thoracic aortas from wild-type and pendrin null mice. Although pendrin expression was not detected in the aorta, pendrin gene ablation changed contractile protein abundance and increased the maximal contractile response to PE when normalized to cross sectional area (CSA). However, the contractile sensitivity to this agent was unchanged. The increase in contractile force/cross sectional area observed in pendrin null mice was due to reduced cross sectional area of the aorta and not from increased contractile force per vessel. The pendrin-dependent ...
Objective: To establish a bedside test with ultrasonography for evaluation of foot muscle atrophy in diabetic patients.. Research Design and Methods: Thickness and cross sectional area of the extensor digitorum brevis muscle (EDB) and of the muscles of the first interstitium (MIL) were determined in 26 diabetic patients and in 26 matched control subjects using ultrasonography. To estimate the validity findings were related to the total volume of all foot muscles determined at magnetic resonance imaging (MRI-FMvol). Furthermore, the relations of ultrasonographic estimates to nerve conduction, sensory perception tresholds and clinical condition were established.. Results: In diabetic patients the ultrasonographic thickness of EDB (U-EDBt) was 6.4 ± 2.1 mm (mean ± SD) vs. 9.0 ± 1.0 mm in controls (p,0.001), thickness of MIL (U-MILt) was 29.6 ± 8.3 mm vs. 40.2 ± 3.6 mm in controls (p,0.001) and the cross sectional area of EDB (U-EDBCSA) was 116 ± 65 mm2 vs. 214 ± 38 mm2 in controls (p,0.001). ...
The extent of luminal narrowing varies with underlying plaque morphology. TCFAs and fibroatheromas have the least luminal narrowing while lesions with acute plaque rupture, haemorrhage, or healed repair sites show the most stenosis. Over 74% of TCFAs have , 75% cross sectional area luminal narrowing (equivalent to , 50% diameter stenosis). Healed and acute plaque ruptures show the greatest luminal narrowing with 46% and 43%, respectively, containing , 75% cross sectional area narrowing. In contrast, only 26% of TCFAs show severe luminal narrowing (fig 3B). In a population where sudden cardiac death is the first manifestation of coronary disease, these morphologic findings strongly suggest that TCFAs are precursors to acute ruptures and healed plaque ruptures are often clinically silent.. TCFAs with ⩽ 50% diameter stenosis may be the ideal candidate lesions one should first attempt to identify and treat as a measure to reduce the incidence of myocardial infarction in high risk patients. If a ...
The present invention relates to a system of modeling a three dimensional target object which is represented by a plurality of cross-sectional images in order to provide a representative corresponding three dimensional model. The invention selects an initial model from a plurality of available initial models. This selection involves identifying an initial model based on physical similarity to the target object and then superimposing an initial model upon the target object, for each of the plurality of cross-sectional images. A determination is then made of an intersection contour of the initial model and a cross-sectional image of the target object and the determined intersection contour is refined in order to more closely delineate the target object. By sub-sampling points which represent the refined determined intersection contour, the invention obtains a sub-sampled contour dataset. The initial model is then adjusted towards the sub-samples contour to obtain a representative three dimensional

A dilator retractor and the dilators that are used for minimally invasive spinal surgery or other surgery are configured to accommodate the anatomical structure of the patient as by configuring the cross sectional area in an elliptical shape, or by forming a funnel configuration with the wider end at the proximate end. In some embodiments the distal end is contoured to also accommodate the anatomical structure of the patient so that a cylindrically shaped, funnel shaped, ovoid shaped dilator retractor can be sloped or tunneled to accommodate the bone structure of the patient or provide access for implants. The dilator retractor is made with different lengths to accommodate the depth of the cavity formed by the dilators.

10 Pro Tips to Increased Gains. Increase your workout productivity. 1. Get stronger on basics. If your goal is to build muscle in record time, then you need to get stronger. Physiologically speaking, as a muscle gets stronger (produces more force), the cross sectional area grows larger (i.e., it hypertrophies). Your wo
During a CT scan, a thin x-ray beam rotates around the patient. Detectors measure the x-rays and a computer creates a cross-sectional image or "slice" of that part of the body. A three-dimensional image can be created by combining the slices. The images interpreted by a radiologist (a doctor specialized in the reading of x-rays), who will report the results to your doctor. Your doctor will then provide you with this information ...
Individual projections create a cross-sectional image of the object as if it had been perfectly cut in half. The process, which functions much like when a doctor takes a CAT scan of a patients brain to look for abnormalities, renders a highly-detailed perspective that allows for unparalleled diagnostic analysis of the object. Even the most minor of structural flaws can be measured for repair or rendered large for study. Multiple X-ray images can be arrayed to create a single, three-dimensional model for a more in-depth consideration.. This technology allows for new possibilities in non-destructive testing:. ...

N2 - Although arginine vasopressin (AVP) has been shown to be a promising drug during cardiopulmonary resuscitation (CPR), concern has been raised about the potential for AVP-mediated vasoconstriction of the coronary arteries. In a prospective, randomized laboratory investigation employing an established porcine model, the effects of AVP on haemodynamic variables, left anterior descending (LAD) coronary artery cross sectional area employing intravascular ultrasound (IVUS), and return of spontaneous circulation were studied. During sinus rhythm, the LAD coronary artery cross sectional area was measured by IVUS at baseline, and 90 s and 5 min after AVP ...
A graphical regression between Bankfull cross sectional area and drainage area is typically performed on a log-log plot. Cross-sectional area is measured using techniques discussed earlier, typically at a representative riffle or some average riffle area where Bankfull is readily determined. As would be expected, Bankfull cross-sectional area typically increases with drainage area, but again, deviations exist within and between regions. ...
0059] The unit weight of a wireline cable, for example lbs/ft, may be reduced at lower portions by reducing the unit weight of the strength members at the lower portions of the cable. One skilled in the art will appreciate that the unit weight of the strength members is directly proportional to the density of the strength member material and the cross sectional area of the strength members at a location along the cable. By reducing the total cross sectional area of the strength members at a lower location with respect to an upper location, and assuming a substantially constant material density, the unit weight of the cable will be proportionately lighter at the lower location. The technique of tapering the strength members, described above, is one way to accomplish this reduction. FIG. 13A-C show other embodiments wherein the total cross sectional area of the strength members of the cable may be reduced at lower locations. FIG. 13A shows an upper end of cable 1300 having an inner layer 1302 and ...
During Rutherford cable production the wires are plastically deformed and their initially round shape is distorted. Using X-ray absorption tomography we have determined the 3D shape of an unreacted Nb3Sn 11 T dipole Rutherford cable, and of a reacted and impregnated Nb3Sn cable double stack. State-of-theart image processing was applied to correct for tomographic artefacts caused by the large cable aspect ratio, for the segmentation of the individual wires and subelement bundles inside the wires, and for the calculation of the wire cross sectional area and shape variations. The 11 T dipole cable cross section oscillates by 2% with a frequency of 1.24 mm (1/80 of the transposition pitch length of the 40 wire cable). A comparatively stronger cross sectional area variation is observed in the individual wires at the thin edge of the keystoned cable where the wire aspect ratio is largest ...
Blood flow in series increases the resistance; blood flow in parallel decreases the resistance (TPR).. By blocking the umbilical veins you have in respect limited the excess flood flow to the placenta.. This reduces the flow in parallel circulation; thus increases the TPR. (MAP = cardiac out put times TPR). This is because the total cross sectional area is reduced. From this, there is an increased pressure in the fetal circulation.. The baroreceptors located immediately distal to the bifurcation of the common carotid artery would sense a high pressure and increase their afferent signal via CN9.. This Reduces the sympathetics and increases the parasympathetics via CN10 (vagus).. Thus, reducing the heart rate!. ...
Suppose we have a PFR with the reaction B + 3C --, 2D, where B, C, and D are gaseous species. We are going to assume that the shear stress at the wall is very small so that the pressure gradient along the tube is very low, in which case the total pressure P is constant at the inlet pressure throughout the reactor. We are also going to assume that the heat of reaction is zero, so that the temperature throughout the reactor is constant at the inlet temperature T. We are going to assume ideal gas behavior, and that B, C, and D comprise the entire flow stream. Let x be the axial position along the reactor, and let v(x) represent the axial velocity a position x. Let A be the cross sectional area of the tube. Let yB(x), yc(x), and yd(x) represent the mole fractions of the three species, and let Mb, Mc, and Md represent the molecular weights of the three species ...
This paper presents the evaluation of a miniature liquid microflow sensor, directly integrated on a PCB. The sensor operation is based on the convective heat transfer principle. The heating and sensing elements are thin Pt resistors which are in direct electrical contact with the external copper tracks of the printed circuit board. Due to the low thermal conductivity of the substrate material, a high degree of thermal isolation is obtained which improves the operating characteristics of the device. The sensor is able to operate under both the hot-wire and the calorimetric principle. In order to fully exploit the temperature distribution in the flowing liquid, multiple sensing elements are positioned in various distances from the heater. A special housing was developed which allowed implementation of the sensor into tubes of various cross sectional areas. The sensor sensitivity and measurement range as a function of the sensing element distance were quantified. A minimum resolution of 3 μL/min and a
I would do a quick and dirty look at it by taking the load point as the fixed end of a cantilever beam and the force applied at the free end. That will give you the max bending moment and the resultant max bending stress. With only 72 N as your force, you will have plenty of saftey factor if you go with aluminum or steel with a decent cross sectional area. It shouldnt have to be very big. I would assume that dynamic forces will not be an issue here, i.e the speeds are low and the impact forces are negligible ...
A thermal treating apparatus and process providing convection thermal transfer for elevated processing temperatures and chemical treatment. A recirculation plenum for passage of spent treatment fluid from and fresh treatment fluid to a treatment chamber may contain a thermal control source, a chemical control source, and a blower to provide predetermined programmable temperatures and chemical environments to articles in the treatment chamber. Decreasing cross sectional areas along the length of the treatment chamber cause introduction of fresh treatment fluid at different locations along the length of the treatment chamber to achieve desired uniform thermal and chemical treatment of articles along the length of the treatment chamber.

Background Content: This case study examined the effects of a single Prolotherapy injection series on the left iliolumbar ligament. The ligament measurements were split between medial and lateral portions of the iliolumbar ligament and we hypothesized that growth would occur increasing the cross sectional area and thus provided added stability to the pelvis and lumbar spine.. Purpose: The purpose of our study was to answer two questions: 1) how do you know that the Prolotherapy injectant actually reaches the ligamentous structure you are attempting to heal; and 2) how long does it take for the ligament to recover?. Study Design: Single case study.. Methods: One subject, 32 year-old female with no history of lower back pain (LBP) participated in our study. Her job tasks as a physical therapist required her to twist turn and bend; putting pressure on her pelvis and ligamentous system. The primary author (A.A.) assessed her pelvic ligaments which lead to using a specified Prolotherapy solution for ...

DDD typically begins with small tears in the annulus of the disc (elastic outer ring of collagen fibers) and can lead to a decrease in the water content of the nucleus of the disc (soft gel center). The degenerative cascade of DDD can lead to disc bulging, development of bone spurs (called osteophytes), and loss of disc space height and/or alignment, which can cause nerve impingement. DDD can also lead to degenerative instability, the loss of the ability of the spine under physiologic loads to maintain its pattern of normal movement due to disc degeneration.. ...
The invention provides encircling devices by which anatomical structures, such as blood vessels, fallopian tubes, ureters, vas deferens and outer nerve sheaths are anastomosed. Such an encircling device provides an opening that receives an end of a tubular anatomical structure having a prepared opening, and the tubular structure is anastomosed to a second anatomical structure having a prepared opening by tethering the two structures to the encircling device holding the structures under radial stress in apposition to each other to form a fluid-tight peripheral seal around their openings. Encircling devices are also used to join a tubular anatomical structure to a second anatomical structure having a cavity, e.g., a fallopian tube to a uterus or a uterer to the bladder. The tubular structure is received in the opening of the encircling device and tethered thereto to hold its end open, and then the encircling device is extended through a passageway in the second anatomical structure by means of a trocar,

Computed tomography (CT or CAT scan) is a noninvasive diagnostic imaging procedure that uses a combination of x-rays and computer technology to produce cross-sectional images (often called slices), both horizontally and vertically, of the body. A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, and organs. CT scans are more detailed than standard x-rays.. In standard x-rays, a beam of energy is aimed at the body part being studied. A plate behind the body part captures the variations of the energy beam after it passes through skin, bone, muscle, and other tissue. While much information can be obtained from a standard x-ray, a lot of detail about internal organs and other structures is not available.. In computed tomography, the x-ray beam moves in a circle around the body. This allows many different views of the same organ or structure. The x-ray information is sent to a computer that interprets the x-ray data and displays it in a two-dimensional (2D) ...
The CT (Computed Tomography) scan or the CAT (Computer-Aided Tomography) scan is a diagnostic procedure that takes a detailed cross-sectional x-ray picture of a "slice" of the body.. To get a CT scan, the patient lies very still on a table, which is slowly moved horizontally while the x-ray machine rotates around the patient and takes pictures from many angles. A computer then combines the pictures into a very detailed cross-sectional image. The length of the procedure depends on the areas to be x-rayed. For the chest area, the procedure takes about 20 seconds.. CT scans can show the shape, size and the exact location of organs and tissues in any "slice" of the body more clearly than other diagnostic tools. This technique can help find enlarged lymph nodes, which might contain cancer that has spread from the lung. CT scans are more sensitive than routine chest x-rays in finding early lung cancers. CT scans are also used in detecting masses in the liver, adrenal glands, brain and other internal ...
Computerized Tomography (CT Scan or CT) combines a series of x-ray views taken from many different angles and computer processing to create cross-sectional images of the bones and soft tissues inside your body. A CT scanner is a tube (shaped like a donut) surrounded by a giant magnet. The patient is placed on a moveable bed that is inserted into the magnet. Occasionally, patients require injections of liquid intravenously to enhance the images of the study. CT Scanning time depends on the exact area of the body being studied, but ranges from 5 to 30 minutes.. ...

We found that in healthy elderly men, preservation of whole brain volume was associated with larger total neck muscle cross-sectional area. Therefore in an elderly cohort, those that have a smaller muscle bulk have undergone more brain atrophy. This finding supports the common cause hypothesis, by demonstrating that the rate of sarcopenia and ARCD may occur in parallel within individuals, driven by core underlying biological processes. However, we found no significant association between total neck muscle CSA and ventricular volume (a different measure of brain atrophy), or hippocampal or cerebellar volumes.. We unexpectedly found that total neck muscle CSA was significantly negatively associated with estimated prior cognitive ability (NART) after adjustment for ICA and age, but we found no significant association between total neck muscle CSA and current cognitive abilities. This suggests that those with lower prior cognitive ability may have larger muscles in old age. Muscle mass in old age is ...
Background. Do pressure dependent tracheal obstructions (PDTO) often seen during bronchoscopy in COPD patients affect pulmonary function tests and breathing symptoms? Method. Model study. A garden hose was compressed from one side to simulate the posterior wall of the trachea bulging into the lumen. For two obstruction lengths - 3 cm and 12 cm, the hose was increasingly compressed in eight steps. Resistance was measured at each step for airflows 1 l/s through 9 l/s, and digital photos of the luminal area were taken which were used by a computer to estimate the cross sectional area reduction and the corresponding distance between the bulging (posterior)and the opposite (anterior) wall (AP-distance).. Patient study. 104 stable COPD patients studied by pulmonary function tests and bronchoscopy. The tracheal obstruction was observed during forced expiration and cough, and the cross sectional area reduction was estimated using the results from the model study. ...

Results Thirty stents were deployed. Before stenting, the mean vessel diameter was 3.4±0.21 mm at point A, 3.06±0.18 mm at B, 3.16 ± 0.21 mm at C, 2.67 ± 0.27 mm at D, and 2.56 ± 0.23 mm at E. The deployment of two stents resulted in statistically significant increases in both the average vascular diameter and cross sectional area (CSA) at points C (3.51±0.22 mm and 9.76±1.17 mm2, P= 0.0006 for diameter and 0.001 for CSA, respectively) and E (2.88±0.32 mm and 7.28±1.46 mm2, P= 0.01 for diameter and 0.02 for CSA, respectively) compared with pre-stenting. At angiographic follow-ups compared with before stenting, significant increases were documented at point C (3.42±0.22 mm and 9.42±1.37 mm2, respectively) at first angiographic follow-up but at points A (3.62±0.45 mm and 10.51±2.37 mm2) and B (3.26±0.24 mm and 8.47±1.26 mm2) at second angiographic follow-up. No significant vascular stenosis was demonstrated at double stent segment compared with single stent or native artery segments. ...
A Matlab Simulink model was developed reproducing each vessel section by a distensible compartment. Therefore the cerebral vascular tree was divided into 13 sections from carotid artery to venous sinuses and the pulsatile carotid artery and sinus pressure were inputted as Fourier series. The cross sectional area was varied according to literature data and flow resistance was implemented taking into account the rheological characteristics of blood. The Windkessel function and relaxation properties of vascular walls were integrated by a Voigt model, enabling the variation of wall properties for each section individually. Due to the distensible vessel walls each section interacts with the CSF compartment and autoregulation was implemented by a simple proportional controller. After parameterisation mean pressure and pressure amplitude in the vessel sections showed good accordance with literature values [4]. ...
Introduction: Severe pulmonary hypertension (PH) is an unusual complication in COPD, and a distinct phenotype has been evoked.. Objectives: We evaluated whether computed tomography (CT) can support this hypothesis, by identifying airways and/or small vessels.. Material and Methods: Between 2009 and 2013, 116 COPD patients underwent during a period of disease stability pulmonary function tests (PFT), CT of the chest and right heart catheterization. Among them, 55 subjects had no other condition to explain PH. 20 had severe PH (mean arterial pressure [mPAP]≥40 mmHg) and 35 patients with mild-to-moderate (mPAP≥25; n=20) and without PH (mPAP,25 mmHg; n=15) were chosen as controls. The percentage of total cross sectional area of vessels less than 5 mm2 for the lung area (%CSA,5) and 5 to 10 mm2 (%CSA5-10) were measured on CT examinations (ImageJ) and compared between groups. Correlations were searched between %CSA and PFT values, emphysema (Low Attenuation Area%) and mPAP.. Results: Severe PH ...
Both are twisted multi-conductor products that find use in RF applications but otherwise the two are substantially different. While litz wire may be produced with 15 or fewer individual strands, for high frequency applications the constructions often consist of many bundles with up to 2000 individual strands of ultrafine wire. Litz wire is constructed with a loose lay (,0.25 to 2 twists per inch) to minimize the lineal increase in resistance produced by twisting and individual wires are insulated with single build insulation to maximize the cross sectional area of copper conductor. Polyurethane base insulation is used almost exclusively for the individual wires due to its low RF loss characteristic, wide availability and moderate cost. The constructions of fine and ultrafine strands may be helically wrapped with nylon or other textile yarn to bind and maintain the litz wire in a circular configuration and to protect the thin film insulation coatings from abrasion. In recent years extruded ...

Long intervals take two minutes or more and are very tiring. In interval training, a runner may run a quarter mile 12 times, averaging 1 minute, with a 110-yard slow jog between each. A weightlifter may lift a heavy weight ten times in a row and then repeat another set of ten. Runners run intervals as fast as they can and recover enough to run the same fast pace several times. Runners need very short recoveries between intervals, usually only about 30 seconds; but weight lifters need much longer recoveries, at least two and a half minutes. Runners become short of breath and feel a burning in their muscles when lactic acid starts to accumulate in muscles, but it takes only a few seconds for a trained athlete to recover between each hard run. On the other hand, weight lifters feel burning caused by tearing of the muscle fibers and it takes a much longer time for the pain to disappear so they can lift very heavy weights again ...
My most immediate reaction to the article was to find out what she looks like. I make no apologies. Im a compassionate progressive, but Im not a politically correct compassionate progressive.. As I suspected, she looks extremely physically fit, but also attractive and traditionally "feminine". I suspected that for a variety of reasons. First of all, the whole situation of being hassled by intimidated sexists for being "masculine" suggests that the woman in question is likely to be attractive. If a less attractive woman succeeded in the same sport, sexists would merely sneer at her appearance rather than getting worked up. Second of all womens weight lifting is pretty heavily drug tested, and although there probably are athletes who test the limits of that testing (as in any relatively major sport), quite bluntly, it would mainly be contenders for the gold from countries with major weight-lifting programs, a group which does not include the UK, who would be most likely to do that. Obviously, ...

Intravascular ultrasound (IVUS) is the most favorable imaging modality that often used in coronary artery catheterization procedures and provides cross-sectional images of arterial wall structures and extend of atherosclerosis disease. Although several techniques have been developed to classify atherosclerotic tissues, deploying IVUS radiofrequency (RF) backscattered signals and/or grayscale images their clinical applications have seen limited success. In this paper, we propose a unified methodological framework from data collection, histology preparation, registration, feature extraction, and classification to achieve a reliable in vitro trained tissue characterization classifier for in vivo applications. Finally, the results from proposed algorithm is compared with state of the art virtual histology (VH) technique ...
Thank you very much Forrest for your answer. I dont think I have memory problems (my computer has a 32 GB memory). Here is my code to draw the 100-m buffers with the function buffer (package raster): r1 ,- r ## r is the original raster and has a resolution of 10m r1[(r1[]!=2 & r1[]!=5)]=NA plot(r1) r2 ,- buffer(r1, 10) I also tested the function distance (package raster): r1 ,- r ## r is the original raster and has a resolution of 10m r1[(r1[]!=2 & r1[]!=5)]=NA plot(r1) r3 ,- distance(r1) In the two cases, I stopped the functions afer 5 hours as this was too long ! For the moment, I havent find solutions. Thanks a lot for your time. Have a nice day.

Computed Tomography (CT or CAT) Scan of the Brain (Head CT Scan, Intracranial CT Scan) Procedure Overview What is a CT or CAT scan of the brain? Computed tomography (CT or CAT scan) is a noninvasive diagnostic imaging procedure that uses a combination of x-rays and computer technology to produce cross-sectional images (often called slices), both horizontally and vertically, of the body. A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, and organs. CT scans are m ...
Cardiac-computed tomography is an X-ray imaging technique that uses a computer to produce cross-sectional images. Also referred to as computerized axial tomography, or CT, CAT scan, multidetector CT or MDCT, it can be used to examine the heart and blood vessels for problems. It is also used to identify the blood vessels in the brain affected by stroke.. ...

Trials were conducted over two periods of 27 days on men and women who were about 11.4 kg overweight. The trial periods were separated by washout intervals of four weeks. Participants ate a typical northern diet during the trials, meaning breakfasts could include everything from French toast with maple syrup to yoghurt, while dinners might consist of spaghetti with meat sauce, raw celery with carrots and a date square. On the first and last day of each trial period, the participants were subjected to magnetic resonance imaging (MRI) to obtain 40 cross-sectional images of their bodies to see where the fat was located. It was observed that on a functional oil diet, participants had decreased their total body volume and upper body fat. Prof. Jones explained that the functional oil is not stored in the body as fat. It is directed towards the liver for combustion and burned as energy. By combusting, rather than absorbing the functional oil, male participants lost an average of 2.2 kg/month, while the ...
Spatial data comes in many forms. Although much of the GIS research and teaching at CSDE revolves around data describing contiguous polygons (such as census tracts and counties), there are other ways of representing spatial information that are equally important to demographers. This course introduces point and raster data types and some of the tools for analyzing them. We begin with raster data and the basic mathematical transformations where this data type excels. Next, we introduce two types of point data: events and samples, and work through techniques for measuring clustering using data on crime in Seattle. The class culminates with the development of two types of raster surfaces: density and interpolation, which both transform point data to raster form.. ...
A pilot study was conducted to assess the suitability of transcribing the Concawe CSAs into Chesar version 2.2. The aim was to identify areas that could affect the effective use of the Chesar tool as a vehicle for developing CSAs for PS with respect to human exposure and, where required, to describe possible methods for handling limitations resulting from the use of the Chesar tool.. ...
Post-meeting note: A revised version of the CSAs was circulated vide LegCo Paper No. CB(1) 1177/96-97 dated 2 April 1997.) PAS/EM elaborated on the Administration s response to the outstanding issues arising from the discussion on 25 February 1997, as contained in its letter dated 12 March 1997. The Administration accepted that workers working in vehicles in a public place, who were not the drivers nor the passengers, should be protected under the Bill. The CSAs tabled had proposed amendments to this effect. PAS/EM also reported that the Labour Advisory Board (LAB) had met to consider the Bills Committee s suggestion to amend clauses 6, 7 and 8 of the Bill and agreed that general duties provisions similar to those in the Factories and Industrial Undertakings Ordinance (FIUO) should be included in the Bill. Furthermore, they considered a one-year grace period necessary for the introduction of the penalty clause for breach of the general duties provision by an employer, occupier of premises, and ...

Contrary to popular belief, your muscles dont turn to mush as soon as you stop lifting. In fact, a recent study of recreational weight lifters found that 6 weeks of inactivity resulted in only a slight decrease in power (10 percent after 2 weeks) and virtually no drop-off in size or strength. You could go the whole summer without pumping iron--as long as youre keeping fit with activities such as swimming or tennis. These sports help retain muscle mass and offer the perfect physical and mental break from the tedium of the gym. Come fall, you can return to the gym refreshed and ready to take your workouts to the next level. ...
I agree though we shouldnt let the topic wonder. Although, a big part of getting bigger is getting stronger, too. As a light weight lifter I find it very difficult to get strong and keep my weight roughly the same. Infact as time goes on im starting to think its impossible. But, strength training in a nutshell can be broken down to the following - lift heavy things, whilst in a caloric surplus.... Sounds familiar.... You could argue that you wont get big as quickly, but that depends on the person. If youve stopped making gains on your hypertrophy routine, chances are the best thing you can do is drop the volume, increase the intensity (lift heavier) for a while. Get stronger, basically. Then that would pave the way for size gains when you increase the volume again ...
Benching, bench pressing, powerlifting, what ever you want to call it is a sport that many have taken up. It is the type of sport that gives the performer killer abs, biceps and strength; It is the kind of sport that takes a man from being ordinary to being the bedroom wall paper of some girl in a another continent from the one the man is. it is the dream of many to have the type of strength and abs found especially in people like the rock and Ryan Kennelly. However, the sports takes resilience, courage, knowing that you might get hurt and not caring much about that and a great diet to support the massive work out. The result? A gigantic muscle man whose name everyone will know because of the internet.. After Justin Forsett (The Raven) posted that video of himself lifting 115 lb this year, it got most people wondering, who are the best weight lifters in the world? How much weight have they lifted and what do they look like?. Ryan Kennelly. This is a name you should already be familiar with if ...

If youre looking for the ultimate lifter to withstand even the most demanding racing conditions, look no further. The COMP Cams Elite Race Lifters feature a host of advantages over competing race lifter designs, including an SAE 8620 stainless steel alloy body that is CNC-machined and REM-finished, SAE 9310 steel alloy wheels that are micro-polished and micro-sized and needles that are made from 52100 bearing steel and micro-sorted with a controlled contour profile.. These lifters feature an exclusive body design that does not include an oil band, maximizing rigidity and reducing lifter bushing wear. While the construction and body design make them incredibly strong, the Elite Race Lifters are also lightweight, with each lifter weighing less than 100 grams individually. All lifter bodies are "tall" and will clear both stock and aftermarket .300" tall lifter bores and will properly fit either 5/16" or 3/8" ball pushrods.. One of the most critical elements of this lifter design is the fact that ...
The CT images used in the app come from nonpathological CT scans. At first we thought of using images from the [U.S. National Library of Medicine] Visible Human Project, and we acquired the relevant permission to do so. However, we soon realized that the Visible Human Project did not contain all parts of the human anatomy, and we wanted our images to have a consistency and continuity. So we decided to go with the option of using real patient scans. Obviously, we were very careful in obtaining copyright and ethical clearance from the patients and the hospital we worked with. Who is the target audience for CT Anatomy, and how do you envision it will be used?. Our primary target, of course, is medical professionals -- especially radiologists and radiologic technologists -- but anyone with an interest in cross-sectional anatomy can use and benefit from the CT Anatomy app. The volume of information in regards to the anatomical structures described and the ease of use in the app goes beyond the strict ...
We examined the effect of growth hormone (GH) on connective tissue of tendon and skeletal muscle during immobilisation and re-training in humans. Young men (20-30 years; n=20) were randomly assigned to daily recombinant GH (rhGH)(33-50μg/kg/d) or placebo (Plc), and had one leg immobilised for two weeks followed by six weeks of strength training. Cross sectional area (CSA), maximal muscle strength (MVC) and biomechanical properties of m.quadriceps and patellar tendon were determined. Muscle and tendon biopsies were analysed for mRNA of collagen (COL-1A1/3A1), insulin-like growth factors (IGF-1Ea/Ec), lysyloxidase (LOX), matrix metalloproteases (MMP-2 and -9), decorin and tenascin-C. Fibril morphology was analysed by transmission electron microscope (TEM) to detect changes in fibril diameter distribution. In muscle the CSA and MVC declined with immobilisation, and recovered with rehabilitation similar in both groups. Likewise, both groups increased in IGF-1Ea/Ec and COL-1A1/3A1 expression in ...
Cribb et al (2007) [29] observed greater improvements on 1RM, lean body mass, fiber cross sectional area and contractile protein in trained young males when resistance training was combined with a multi-nutrient supplement containing 0.1 g/kg/d of creatine, 1.5 g/kg/d of protein and carbohydrate compared with protein alone or a protein carbohydrate supplement without the creatine. These findings were novel because at the time no other research had noted such improvements in body composition at the cellular and sub cellular level in resistance trained participants supplementing with creatine. The amount of creatine consumed in the study by Cribb et al was greater than the amount typically reported in previous studies (a loading dose of around 20 g/d followed by a maintenance dose of 3-5 g/d is generally equivalent to approximately 0.3 g/kg/d and 0.03 g/kg/d respectively) and the length of the supplementation period or absence of resistance exercise may explain the observed transcriptional level ...
Background: Abnormal Tissue Doppler imaging (TDI) velocities are detectable even in the pre-hypertrophic phase of Fabry disease (FD) cardiomyopathy.. Hypothesis: Impairment of cardiomyocyte relaxation and contractility is a main determinant of cardiac dysfunction in FD.. Methods: Active and passive tension before and after protein kinase A (PKA) and myofilament protein composition were determined in isolated cardiomyocytes from ventricular biopsies of 8 males (41±11 yrs) with untreated FD. Myofilament structure was analysed by electron microscopy. Cardiomyocyte cross sectional area, percent area occupied by glycosphyngolipids vacuoles and extent of fibrosis were morphometrically evaluated. Controls were ventricular biopsies from donor hearts and from patients with mitral stenosis.. Results: Resting tension was higher in FD cardiomyocytes than in cells from controls (9.2±2.4 vs 3.5±1.7 kN/m2, p, 0.001). Active force was lower (2.4±0.9 vs 20.3±3.0 kN/m2, p,0.001) and correlated with ...
We discuss the design and implementation of forward-imaging instruments for optical coherence tomography (OCT), which require the delivery, scanning, and collection of single-spatial-mode optical radiation. A hand-held surgical probe for use in open surgery can provide cross-sectional images of subsurface tissue before surgical incisions are made. A rigid laparoscope for minimally invasive surgical OCT imaging provides a simultaneous en face view of the area being imaged. OCT imaging is demonstrated on in vitro human specimens.. © 1997 Optical Society of America. Full Article , PDF Article ...
Similar to a CT scan of internal organs, the OCT instrument uses light to rapidly scan the eye and give high resolution cross-sectional images of the retina. A beam of infrared light is scanned across the retina. The instrument collects the reflected light and measures its "time of flight" delay. That is: light, coming from deeper layers, takes longer to return compared to light from more superficial layers. The light does not interfere with or affect the retina. The various reflections are then built up into an image with computer generated colors. It is neither photography nor an x-ray. ...
Magnetic Resonance Imaging is a diagnostic technique that produces computerized images of internal body tissue and is based on magnetic vibration of tiny molecules within the body induced by the application of radio waves. With no known side effects, MRI provides cross-sectional images of muscles, nerves, ligaments, tendons, spinal cord, brain, heart and breast
An accurate description of anatomies and dynamics of vessels is crucial to understand their characteristics and improve surgical techniques, thus it is the basis, in addition to surgeon experience, on which stent design and operation procedures rely. The process of producing this description is user intensive, and recent improvement in image processing of medical3D imaging allows for a more automated workflow. However, there is a need to bridge the gap from a processed geometry to a robust mathematical computational grid. By sequentially segmenting a tubular anatomic structure, here defined by a stereo lithographic (STL) surface, an initial centerline is formed by connecting centroids of orthogonal cross-sectional contours along the length of the structure. Relying on the initial centerline, a set of non-overlapping 2D cross sectional contours are defined along the centerline, a centerline which is updated after the 2D contours are produced. After a second iteration of producing 2D contours and updating

This simple, yet effective training program is highly customizable for beginning weight lifters. Designed for smooth transition to an intermediate routine.
Notice that those are subtle changes. You want to gradually move toward leanness-nothing drastic. That way you retain and even build muscle as you drop that ugly body fat…. As for your workouts, now is the time to introduce an X-centric set for each bodypart. And we suggest you do that on the last set of each big midrange exercise-squats, pulldowns, rows, bench presses, etc.. X-centric is using a slightly lighter weight than your normal 10-rep weight and raising it in one second and lowering in six on every rep. And its an almost magical fat-to-muscle method. Why?. Research shows that lowering slowly throughout the negative stroke causes more micro-trauma in muscle fibers. To repair those microtears, your body uses stored fat for energy.. So you burn off more fat 24/7 as you regenerate and pack on muscle. Nice…. Also, doing a set of seven or eight X-centric reps, at 7 seconds each, gives you a muscle-tension time of almost a minute. That helps expand the sarcoplasm in muscle tissue for new ...
The first thing I do when someone complains about being unable to get under the weight, of fix it overhead, is to look at the width of grip. It was a great surprise when I saw some pictures of Vorobiev, the Russian world snatch record holder, to see how narrow was his hand spacing. The Russians use this narrower hand spacing, often giving up certain benefits of the wider grip to gain this dubious one: A little extra pulling power is possible with the narrow hand spacing on the bar: however, it raises the center of gravity of he lifter to a high "danger point" . . . an inch, or at the most an inch and a fraction, but enough to exert considerable influence on the lifters stability when he has a weight at arms length overhead and is in the deep split or squat position. Thats one cause of inability to control a weight and keep a good balance. Vorobiev, an experienced lifter, of course is used to his style, but the danger lies in the probability of a bunch of young and enthusiastic lifters ...

The differential cross-section for the production of a W boson in association with a top quark is measured for several particle-level observables. The measurements are performed using 36.1 fb(-1) of pp collision data collected with the ATLAS detector at the LHC in 2015 and 2016. Differential cross-sections are measured in a fiducial phase space defined by the presence of two charged leptons and exactly one jet matched to a b-hadron, and are normalised with the fiducial cross-section. Results are found to be in good agreement with predictions from several Monte Carlo event generators.. ...
