We calculate the light curve and spectra near the peak and the self absorption break, for an adiabatic blast wave described by the Blandford-McKee solution, considering the emission from the whole region behind the shock front. The expected light curve and spectra are flat near the peak. This rules out the interpretation of the sharp peak observed in the optical afterglow of GRB970508 as the ex...

background: this study aimed to determine the seroprevalence of canine visceral leishmaniasis in meshkin-shahr district as endemic areas of human visceral leishmaniasis (hvl) for presenting control program of hvl to health authorities.  methods: a seroepidemiological study to determine seroprevalence of canine visceral leishmaniasis (cvl) among owner­ship dogs using direct agglutination tests (...

the climatic conditions of sistan plain and its coexistence paved the way for settlement of human populations, establishment of various residential sites and perhaps more importantly, emergence of civilizations that have given rise to the great cities such as shahri-sukhteh and tang-e gholaman.   although the accumulation of residential areas in the plain during different times and their proxim...

A mid-term study (2003-2013) of polycyclic aromatic hydrocarbons in Gulf Trieste sediments was conducted at seven sampling sites. The PAH spatial and temporal distribution origin were determined. sampled with a gravity core sampler. After extraction PAH, their concentrations determined by gas chromatography. results the show variability. highest mean concentration measured marina Portoroz (1168...
