Background. Abdominal cocoon, or sclerosing encapsulating peritonitis, is a rare condition characterized by partial or total encasement of small bowel and mesentery by a thick fibrocollagenous sack that looks like a cocoon. Within the sack, bowel loops are drawn together causing intestinal obstruction.Case presentation. We report on a 57-year-old female patient who developed a very unusual comp...

A triethylaluminium(TEAl)-modified Phillips ethylene polymerisation Cr/Ti/SiO2 catalyst has been developed with two distinct active regions positioned respectively in the inner core and outer shell of the catalyst particle. DRIFTS, EPR, UV-Vis-NIR DRS, STXM, SEM-EDX and GPC-IR studies revealed that the catalyst produces simultaneously two different polymers, i.e., low molecular weight linear-ch...

Nutrition is the important physiological process, which plays a prime role in the growth and in turn it affects the productivity of the silkworm. The supplementation of different materials along with mulberry leaves to silkworm results higher yield because the production of quality silk mainly depends on larval nutrition. The influence of antibiotic on growth and development of silkworm larva a...

The present study investigated the effect of increasing temperature stress on the thermotolerance of B. mori cross-breed PM x CSR2 and tissue specific differential expression of heat shock proteins at IVth and Vth instars. The larvae reared at 25 +/-1 degrees C and 70 +/- 5% relative humidity were treated as control. Larvae were subjected to heat shock temperatures of 34, 38 and 42 degrees C fo...

in the present study, vibration of cylindrical laminates with different layers and angles were studied. in order to actuate and polarize in radial direction, a piezoelectric layer was located at outer surface of composite shell. laminates were assumed long enough so that plane strain state analysis in 2d can be used properly. in order to satisfy the boundary conditions, variables in terms of fo...

to evaluate the morphological diversity of some almond cultivars and genotypes, an experiment was carried out on 55 iranian and foreign genotypes. twenty-nine quantitative and qualitative characteristics of nuts and kernels as well as 4 phenotypic characteristics of almond trees were evaluated. analysis of variance and means comparisons indicated that all the characteristics of the examined cul...

The abdominal cocoon is a rare cause of intestinal obstruction that is usually diagnosed at the time of laparotomy. It is usually of unknown origin, although at times, it may be seen secondary to a variety of conditions. Tuberculosis is an infrequently implicated cause of abdominal cocoon, and has only occasionally been reported previously in the Literature. This paper presents our experience w...

Bombyx mori cocoon is a natural composite made of silk fibre with a distinctive multi-layer structure that provides mechanical protection for its biological functions. Here we investigate the components, structure and mechanical properties of cocoon layers, and quantify the contributions of the multi-layer structure to the mechanical properties of cocoon. A better understanding of the multi-lay...
