Peak discharge is one of the basic parameters in the design of hydraulic structures. There are various methods for peak discharge determination. Regional flood frequency analysis is based on physical, climatological and hydrological characteristics of basins. The objective of this study is to examine different models for the estimation of quantiles for some catchments in western Iran (namely: G...

Public concern about the welfare of hens kept in conventional cages has become an important issue worldwide. This study examined the effects of conventional cages (CC) and floor pens (FP) on hens’ health and egg production. A total of 84 19-wk-old Bovan Brown hens were randomly assigned into 2-bird cage (n = 12), providing 968 cm2 floor space per hen or 10-bird floor pens (n = 6), providing 371...
in order to study the effect of soil compaction on root and shoot growth of wheat plants (shahriar variety), a greenhouse pot experiment was conducted in guilan university. the study design was factorial with completely randomized in three replications. treatments included three compaction levels; (normal compaction, compaction of ten percent and twenty percent) and two type of soil texture (cl...
the effects of traffic frequency and skid trail slope on dry bulk density, litter mass and rutting are examined. treatments included a combination of four different traffic frequencies (3, 7, 14, and 20 passes of a rubber skidder) and three levels of slope ( 20%.) the results showed that dry bulk density, rut depth and soil displacement increased with the increase of traffic frequency and slope...
this research concentrates on the lithostratigraphy, biostratigraphy, microfacies and sedimentary environment of the asmari and gachsaran formations at southwest firuzabad. the thickness of the studied section in all 608.95 meters that 220.8 meters belong to the asmari formation and 387.95 meters belong to the gachsaran formation (champe and mol members). in the study area, the asmari formation...
abstract over the past two decades, applied linguists and language teachers have shown a great deal of interest in genre-centered approaches , mainly because of pedagogic concerns . this has been due to the need to help non-native readers enhance their ability to understand academic and scientific texts. following swales’ (1981) works on genre analysis, studies of different sections of resear...
