When rails are laid in a railway track, small gaps are left between the ends of adjoining rails to allow for the expansion of the rails when the temperature rises. Rail joints are provided to form a continuous rail path which are normally laid in standard lengths bolted together by fishplates. When two rail joints are exactly opposing each other, they are called square &#10&#10(side by side) jo...

Briggsia hastingsi is described as a new genus and species of gobiesocid fish from a single specimen, 22 mm in standard length, collected in 2 m depth on the southeastern coast of Oman. The genus differs principally from other aspasmine genera in having fewer dorsaland anal-fin rays (4 each) and a shorter head (head length 2.5 in standard length).

in order to evaluate the relationship between morphological characters in rice lines two populations at f3 generation were grown in research field of agricultural sciences and natural resource university, sari, iran, during 2012. statistical analysis on important agronomic traits showed that maximum standard deviation belonged to total grain number followed by filled grains per panicle and grai...

Several sampling gears are used to collect fish in the lentic ecosystem. The collected differ their characteristics and community structure depending on gear. objectives of this study were 1) compare assemblages sampled using four (kick net, cast gill fyke net) Singal (SG), Yedang (YD), Juam (JA) reservoirs, 2) understand fishes by each A total 1887 individuals 14 species, 9113 15 9294 27 speci...

Edentulous patients may be restored with complete-arch implant-supported fixed complete dental prostheses (IFCDPs) on angled distal implants or parallel distributed equally across the mandible to increase area of support. A treatment is presented introduce clinical concept providing edentulous an prosthesison tissue-level in standard length interforaminally and ultrashort distally. structured p...
