The cirrus clouds are a sort of transparent clouds that are barely visible in many satellite images. These clouds form a reflection effect in the images which hide the crucial information in remote sensing. Thus the removal of cirrus effect is essential to have an effective remote sensing over coastal regions and the following proposed algorithms proved to be cirrus-free images. The techniques ...

BACKGROUND Observational learning plays an important role in surgical skills training, following the traditional model of learning from expertise. Recent findings have, however, highlighted the benefit of observing not only expert performance but also error-strewn performance. The aim of this study was to determine which model (novice vs. expert) would lead to the greatest benefits when learnin...

results the mean age of patients was 16.7 ± 2.5 years. there was no statistically significant difference between the two groups regarding gender, age, curve before surgery, and percentage of flexibility. the mean curvature was 70 ± 20.7 in the hr and 64.81 ± 19.4 in the cd group before surgery (p = 0.09); and the mean curvature was 40 ± 16.3 and 26.58 ± 15.37 in hr and cd groups respectively af...

background inguinal hernia is the most prevalent surgical disease in clinical practice. endoscopic inguinal hernia repair has been shown to be slightly superior to open approaches. recent modifications in the minilaparoscopic technique may improve the totally extraperitoneal repair (tep) results. objectives we have performed a prospective study to analyze the feasibility of laparoscopic inguina...

As a psychological and medical journal, GMS Psycho-Social-Medicine places a high premium on the study of the behavioural, medical and social mechanisms that determine health, well-being and illness across the life span. GMS Psycho-Social-Medicine maintains also a vivid interest in the development and refinement of psychometric instrumentation for measuring psychological constructs. This special...

background: the ability of polyclonal antibodies to react with many epitopes of an antigen makes them valuable reagents in research and diagnosis. the aim of this study was purification of mouse igg2a and production of polyclonal antibody against purified mouse igg2a subclass. materials and methods: mouse igg2a was purified by proa affinity. verification method of the purified antibody was sds-...

abstract plant nonspecific lipid transfer proteins (nsltps) are divided into nsltp1 and nsltp2. the existence of an internal hydrophobic cavity, is a typical characteristic of nsltps that serves as the binding site for lipid substrates. in this communication a simple, rapid and low-cost alternative method was developed for purification of nsltp2 from rice paddy. after extracting, final supernat...

The introduction of legislation to control driving under the influence o f alcohol has led to the development and use of a number of instrumental methods for measuring the concen­ tration of alcohol in body fluids.11 Standard methods for blood and urine analysis, based mainly on gas chromatography, are in common use and under laboratory conditions can give results with standard deviations of be...

We present a complete tool chain for automatic controller synthesis using Uppaal Tiga and Simulink. The tool chain is explored using an industrial case study for climate control in a pig stable. The problem is modeled as a game, and we useUppaal Tiga to automatically synthesize safe strategies that are transformed for input to Simulink, which is used to run simulations on the controller and gen...

At first glance, the highly technical procedures and specialization that characterize 21stcentury surgery bear little resemblance to the craft as practiced in Renaissance France and Italy or in the 19th-century operating theaters of Paris, London, or Philadelphia. Yet continuities in Western medical traditions link contemporary surgery to its professional predecessors. To understand the way sur...
