it is definitely necessary to understand the concept and behavior of causation of life insurance policies and its determinants for insurance managers, regulators, and customers. for insurance managers, the profitability and liquidity of insurers can be increasingly influenced by the number of causation through costs, adverse selection, and cash surrender values. therefore, causation is a materi...
The silk of silkworm consists of fibroin fiber coated by sericins. In addition, some nonprotein components were also identified in the sericin fraction. The presence of nonprotein components in the silk has not been well explained. In the present study, methods based on gas chromatography-mass spectrometry were used to identify the metabolites in the cocoon silk from a wild silkworm and two dom...
The effect of mulberry leaves enrichment with riboflavin in 7, 37, 77 and 127ppm concentrations on larval growth and cocoon characteristics of Bombyx mori L., hybrid 103×104 was studied. Silkworm larvae were fed on fresh mulberry leaves of shin inche nevise enriched with riboflavin once a day. All biological and economical parameters were determined by using standard techniques in sericulture. ...
A new species of black fly collected in April from streams 950-1000 m above sea level in Western Anatolia, Turkey, is described on the basis of females, males, pupae, larvae, and polytene chromosomes. Metacnephia phrygiensis new species is structurally and chromosomally distinct from all other known species of the genus, particularly in having unique fixed inversions in chromosomal arms IL and ...

Abdominal Cocoon Syndrome (ACS) or sclerosing encapsulating peritonitis is characterized by intestinal obstruction and ileus as a result of encasement of small intestines totally or partially by a thick fibrous sac. We herein present a patient undergoing Continuous Ambulatory Peritoneal Dialysis (CAPD) therapy for chronic renal failure for 3 years who developed intestinal obstruction and perfor...
Platygaster chilophagae, new species, is described from specimens reared from larvae of Chilophaga virgati Gagné collected and reared in eastern South Dakota. The host larva feeds on the basal meristematic tissues of the inflorescence of Panicum virgatum L. This new species seems to lack immediate affinities with any described Platygaster species in its combination of characteristics, and is co...
The pistachio twig borer moth, Kermania pistaciella Amsel (Lep.: Tineidae) is one of the most important pests of pistachio trees (Pistacia vera L.) in Iran. This study was carried out in two pistachio orchards of Rafsanjan area. Periods of pupal cocoon and adult emergence were recorded in two pistachio orchards for four years. Minimum threshold temperatures were calculated according to the leas...

Silk cocoons are composed of fiber proteins (fibroins) and adhesive glue proteins (sericins), which provide a physical barrier to protect the inside pupa. Moreover, other proteins were identified in the cocoon silk, many of which are immune related proteins. In this study, we extracted proteins from the silkworm cocoon by Tris-HCl buffer (pH7.5), and found that they had a strong inhibitory acti...
