in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
introduction drought is a climatic hazard that occurs in the vast areas throughout the world. it causes physical suffering, economic losses, and environmental instability. drought is a slowly developing very which is phenomenon, and it is very difficult to determine when a dry spell becomes a drought or when a severe drought becomes an exceptional drought. it is usually starting with less drama...
a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...
OBJECTIVES To determine the validity of the histological-histochemical grading system (HHGS) for osteoarthritic (OA) articular cartilage. METHODS Human articular cartilage was obtained from macroscopically normal (n = 13) and OA (n = 21) knee joints. Sections of central and peripheral regions of normal samples were produced. Sections of regions containing severe, moderate, and mild OA changes...
The aim of this paper is to characterize welding of AISI 310 austenitic stainless steel to Inconel 657 for use in oil-refining industries. The welds were produced using four types of filler materials; nickel-based alloys designated as Inconel 82, A, 617, and 310 SS. The interfaces and heat-affected zones were characterized by optical and scanning electron microscopy. Interfaces on the two sides...

abstract: the potato tuberworm, phthorimaea operculella (zeller), is an important insect pest of potato (solanum tuberosum l.) in the storage and field in most parts of the world especially in tropical and subtropical regions due to its close relationship with the host, high reproductive potential and high economic losses. information on host preference, life table parameters and digestive en...
forty monoconidial isolates of magnaporthe grisea were examined, for an identification of vegetative compatibility group and a characterization of genetic diversity, using rep-pcr genomic fingerprinting. the isolates were collected from weeds digitaria sanguinalis (crabgrass), setaria italica (foxtail millet), echinochloa crus-galli (barnyard millet), and some other unknown ones during 2003 - 2...
thirty five monoconidial isolates of the fungal culture collection pyricularia grisea were examined, to identify the vegetative compatibility groups and characterize the genetic diversity of isolates as through rep-pcr genomic fingerprinting. the isolates were collected from ricefields during 1997-1999. genetic diversity of p. grisea isolates was studied as based on dna fingerprinting through r...
based on the latest records of typhlops vermicularis merrem, 1820 from iran, this species is distributed in the northern and southern regions of the country. in this study, new records of typhlops vermicularis are presented and it is shown that distribution range of this species is extended towards the eastern and western iran, and according to the new distribution map, it can be assumed that t...
