The cocoon of the commercial silkworm Bombyx mori is used as a model natural nonwoven composite to formulate a model for structural properties of nonwoven composites. The model is based upon open cell foam structures for the intrinsic undamaged elastic properties using the component materials in the cocoon, combined with the effect of gradual loss of connectivity in the interfiber bonding as th...

"Peritonitis fibrosa incapsulata", first described in 1907, is a condition characterized by encasement of the bowel with a thick fibrous membrane. This condition was renamed as "abdominal cocoon" in 1978. It presents as small bowel obstruction clinically. 35 cases of abdominal cocoon have been reported in the literature over the last three decades. Abdominal cocoon is more common in adolescent ...

A radiative hydrodynamic simulation for a typical, powerful high redshift radio galaxy is presented. The jet is injected at one third the speed of light into a 10000 times denser, homogeneous medium. In the beginning of the simulation, the bow shock consists of a spherical shell that is similar to a spherical blast wave. This shell cools radiatively down to ≈ 10 4 K, providing after 6 × 10 6 yr...

abstract different responses of silkworm larvae under various rearing climate condition would help to obtain better economic performance of some silkworm varities in specific climate conditions. the effect of 4 rearing climate conditions including 1) standard 2) high temperature and humidity, 3) high temperature and low humidity and 4) temperature fluctuation were investigated on the performanc...

The Samarinda silk sarong is a typical made using imported yarn raw materials from China. Quality mulberry plants are needed to support silkworm cultivation (sericulture). obtained by in vitro propagation techniques. purpose of this study was determine the differences quality cocoons and threads feeding cuttings. research stages consisted rearing silkworms, handling spinning. results showed tha...

We present a combined study of single and double K–K electron transfer cross sections along with the single and double K-shell ionization of Ar induced by Si projectiles in the energy range 0.9–4.0 MeV u−1. The charge-state dependence of the normal and hypersatellite x-rays was used to derive the cross sections for the oneand two-electron processes, respectively. The enhancement in the fluoresc...

Diffusion weighted imaging (DWI) is widely used to study microstructural characteristics of the brain. High angular resolution diffusion imaging (HARDI) samples diffusivity at a large number of spherical angles, to better resolve neural fibers that mix or cross. Here, we implemented a framework for advanced mathematical analysis of mouse 5-shell HARDI (b=1000, 3000, 4000, 8000, 12000 s/mm2), al...

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...

Samia cynthia ricini Boisduval Lepidoptera:Saturniidae is a lepidopteran insect that has gregarious behaviour during their larval stage. This research aimed to determine the minimum population limit of larvae can support survival S. c. by observing development time, fecundity, and hatchability eggs produced adult moths under different densities rearing conditions. The was conducted lifecycle at...

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...
