scale insect specimens collected on hordeum sp. (poaceae), dated 24. v. 2003 in khorram abad, lorestan province were identified as exaeretopus tritici williams. this species, which the genus and species is newly recorded from iran, is related to e. harpazi ben-dov, differing mainly in the number of the stigmatic setae and extension of paraopercular pores.

Although typically small in terms of their spatial footprint, landslide hazards are relatively frequent in Northern Iran. In this study, we combine Geographic Information System (GIS), remote sensing and derive a landscape susceptibility map for Bostan Abad County, Iran. The main objective is an inventory evaluation and zonation of natural landslides. This 2685 square kilometer sized county is ...

Background Stray dogs are considered potential reservoirs for zoonotic diseases. Previous helminthic surveys in Iran, have accounted for mainly species of nematodes and cestodes, and rarely digeneans. Methods We accessed 42 car-crashed stray dogs from the Farah Abad Region in the Mazandaran Province (North Iran) between Oct 2012 and Dec 2013, to be inspected for parasites. Helminths were coll...

no-bahar watershed is located, south of khorasan razavi province. geologically, the study area is a part of central iran zone. the rock units are late mesozoic and cenozoic in age in this watershed. no-babhar watershed includes several channels, which among them, only two main channels, motr-abad and solh-abad, have been studied. these rivers are mostly, braided channel in style, with high grad...

Aquatic organisms are used extensively in water quality assessment and ecosystem health quantity scale in streams. Mohammad-Abad creek (Golestan Province) is accounting one of the tributary streams of Gorgan-Rood River. In this study, 21 sites were selected along 25 kilometers of stream long according to ingredient pollutants. Sampling took place each 45 days. After segregation and identificati...

Microbiological water quality monitoring in Niassa province, Northern Mozambique, shows groundwater is not, in general, grossly contaminated though contamination levels are strongly linked to season and to risks observable at the wellhead, especially risks dealing with wellhead hygiene and maintenance. Diarrhea incidence, in general, is greatest in the rainy season suggesting poor wellhead prot...

Abstract. Starting from an exact counting of small and positive cosmological constant states in the Bousso-Polchinski Landscape we recover a well-known approximate formula and a systematic method of improvement by means of the Poisson summation formula. This is a contribution to the special Volume published by the University of Zaragoza in honor of Julio Abad Antoñanzas. En memoria de nuestro a...

Perhaps it is because I am not a professional medicinal chemist, or possibly it is because I am a person that prefers the visual presentation of data as opposed to a long list of numbers in parallel vertical columns; either way, the fact is that the conventional structure–activity relation tables (SAR-tables), which have been and still are the essential item in most medicinal chemistry papers, ...
