Factors affecting the policyholders' satisfaction <of> coldwater fish farmers of Mazandaran Province using agricultural insurance

The goal of this research was considering the reasons of policy holder satisfaction of breeding freshwater fish farms with agriculture insurance in Mazandaran province. The population of this research was the number of 63 freshwater fish breeders in Mazandaran province had assured their farms through Agricultural Insurance Fund during years 88 to 92 and they have utilized questionnaires for field data collection, its validity was approved by experts’ panel and its reliability was approved through utilization of Cronbach’s alpha coefficient (0.85). the variable " Agricultural Insurance Fund has considered on our complain on time" had more sound on satisfaction at the level of %30 followed by the variable " I am satisfied with specification and estimating damage of agricultural insurance" with the level of %28 and" the distance between damage and the time of compensation assessment by Insurance Fund is suitable " in level of %23 and" mangers and personnel attitude of Agricultural Insurance Fund is suitable" in level %20 are effective in measure of satisfaction. Obtained results from the research indicate that the main dissatisfaction of breeders had been about "becoming time-consuming between damage and compensation payment, being unsuitable and defective of specification and estimating compensation process, the way of considering on complain and demand of breeders and the way of managers and personnel of Agricultural Insurance Fund attitude and behavior

Comprehensive investigation on chalcogenide thin film coated multimode optical fiber: Visible evanescent-wave absorption refractometer

In this work, a different insight into the absorption characteristics of the chalcogenide thin film over the visible-wavelength range is studied in detailed. A comparative study of the lossy mode resonance (LMR) dips stem from the evanescent-wave absorption is theoretically and experimentally investigated towards refractive index measurement in aqueous environment. The absorbing layer of thermally evaporated arsenic trisulfide chalcogenide (As2S3) thin film coated onto the low OH etched optical fiber (ChOF) is prepared. X-ray diffraction (XRD), scanning electron microscopy (SEM), and Raman spectroscopy, were used to characterize the chemical species, the crystal structure, and the morphology of the degradation layer confirming the As2S3, thin-film deposition on the curved optical fiber surface. The LMR dips condition hinging on the adoption of the chalcogenide layer was comprehensively explored by referring to the absorption spectra as a function of the wavelength and its thicknesses. Taking the advantage of the chalcogenide absorptive features within the visible spectral range, the results verified that coating even a thin subwavelength thickness of As2S3 chalcogenide on a bare has the ability to provide liquid refractometer with a versatile absorbing features. Our results point to a new path for the development of LMR-based chemical sensors, environmental sensors, or to be combined to the integrated micro-photonics device biosensors

A survey of gastrointestinal helminth of stray dogs in Zabol city, southeastern of Iran

Canids are reservoir for some zoonoses helminthic disease. They are one of main public health problem. The aim of this study was to ascertain frequency of gastrointestinal helminthic infection of stray dogs in Zabol city, southeaster of Iran. In this descriptive study, 30 stray dogs were euthanized, intestine was removed by necropsy. Then, the intestines was opened by scalpel and their contents passed through mesh sieve. The helminth were collected. The nematodes were preserved in 70% ethanol with 5% glycerin and cestodes were preserved in 70% ethanol. The cestodes were stained by acetocarmine. The nematodes were cleared by lactophenol. The genus and species of helminth were identified by identification keys. Twenty two (73.3%) of stray dogs had at least one intestinal helminthic infection. Recovered helminth from stray dogs include: Taenia hydatigena (53.3%), Taenia ovis (20%), Taenia multiceps (6.6%), Mesocestoides spp (10%), Toxocara canis (23.3%), Toxocara cati (3.3%). Data showed that the stray dogs in Zabol city harbor some important zoonoses helminth parasite like Toxocara
