Penile tourniquet syndrome (PTS), a rare urologic emergency, may lead to undesirable results including necrosis and amputation of penis, if not diagnosed and treated appropriately. Sometimes these injuries may be accepted as a forensic case. Miscellaneous objects used for strangulation can be metallic or nonmetallic. Of all ages, the most vulnerable period is infancy. Telogen effluvium is the m...

In recent years, several investigations of the environment-sensitive mechanical behavior of certain crystalline, nonmetallic materials and glasses have been directed toward characterizing the wear behavior of these materials under conditions of sliding and drilling in active liquid environments. Buckley,' for example, examined the change in plastic deformation and friction coefficient of single...

In this paper, a feasibility study was conducted to test whether capacitive sensors could be used to detect water and produce a graph with the minimal amount of equipment and materials. A lab was setup to conduct experiments and retrieve raw data. The data is then processed using a back projection algorithm in an attempt to produce an image of the water from within a nonmetallic pipe. The image...

As a semiconductor material, titanium dioxide has the advantages of stable chemical properties, no pollution and low price, which is widely used in field organic pollutant degradation. The modification methods composite nonmetallic doping for are described. degradation efficiency modified pollutants proposed. disadvantages preparation application pointed out. Finally, development direction future

One of the big challenges of the 21st century is the utilization of nanotechnology for energy technology. Nanoscale structures may provide novel functionality, which has been demonstrated most convincingly by successful applications such as dye-sensitized solar cells introduced by M. Grätzel. Applications in energy technology are based on the transfer and conversion of energy. Following the exa...

conclusions in psychoactive substance dependents, serum routine biochemistry parameters can be used to predict the need for intensive monitoring and treatment programs. results there was a statistically significant difference in the gamma-glutamyl transferase (ggt), uric acid, creatinine, urea, albumin, aspartate aminotransferase (ast) medians between the dependent and control groups (p < 0.05)...

background: in natural waters and/or aquaculture facilities, fish are often exposed to chromium waste and demonstrate cumulative deleterious effects. to our knowledge, there are no studies concerning the effects of trivalent cr on c. carpio hematology. this study presents hematological and some biochemical parameters of common carp, cyprinus carpio, affected by sublethal concentration of trival...

Interference screws are frequently used for fixation of anterior cruciate ligament grafts. When revision surgery is necessary, it is important for the surgeon to recognize variations in interference screw morphology to reduce the potential difficulties in screw removal. The purpose of this observational study is to review the variety of metallic and nonmetallic absorbable interference screws co...

The microstructure obtained as the weld cools from the liquid phase to ambient temperature is called the as–deposited or primary microstructure. Its major components include allotriomorphic ferrite, Widmanstätten ferrite, and acicular ferrite (Fig. 1). There may also be some martensite, retained austenite or degenerate pearlite. These latter phases occur in very small fractions, and are known b...
