Hydatid disease (HD) is an infectious disease caused by echinococcosis. Hydatid cyst (HC) most commonly invades the liver (60-70%) and the lungs (20-25%). However, other parts of the body and even unusual locations can be infected, mimicking a benign lesion that could be easily missed. Primary HC of the chest wall is extremely rare, even in countries where echinococcosis is endemic. We he...

this study was conducted to evaluate the effect of prebiotic short saccharomyces cerevisiae yeast cell wall (ycw) on growth , nutrition and survival rates , blood indices of rainbow trout (oncorhynchus mykiss) were studied . 600 pieces of salmon with an average weight of (1 ± 20) g 4 treatments and 3 replications (each replication 50 pieces of fish) groups. treatments 1, 2, 3 and 4, respectivel...

1. Stress-relaxation tests and creep tests were performed on the bodywall dermis of two sea cucumbers, Actinopyga echinites (Jager) and Holothuria leucospilota Brandt. 2. These viscoelastic connective tissues had mechanical properties which agreed well with those of a four-element mechanical model composed of two Maxwell elements connected in parallel. 3. The elastic stiffness of the dermis of ...

A body wall musculature comprising an outer layer of circular fibers and an inner layer of longitudinal fibers is generally seen as the basic plan in Annelida. Additional muscles may be present such as oblique, parapodial, chaetal, and dorsoventral muscles. The longitudinal muscle fibers do not form a continuous layer but are arranged in distinct bands in polychaetes. Mostly there are four to s...

A sodium silicate-based chemical grout was used in the Karkheh dam site in order to examine the performance of the chemical grouting technique for stabilization of the dam's filter material. Karkheh, an embankment dam with the reservoir capacity of about 7.4 billion cubic meter at the maximum water level, is the largest dam in Iran. The grouting works performed at the dam site, were part of the...

in the present study, mixed convection laminar flow around an adiabatic body in a lid-driven enclosure filled with nanofluid using variable thermal conductivity and variable viscosity is numerically investigated. the fluid around the body in the enclosure is a water-based nanofluid containing al2o3 nanoparticles. the vertical enclosure’s walls are maintained at constant cold temperature and the...
