one of the main objectives of ecosystem management is to preserve the speciesdiversity. many researchers regard higher species diversity as the stability of ecologicalsystems. the aim of this study is to investigate the stability and relationships betweentopographical factors with diversity indices in ghorkhud mountainous rangeland innorthern khorasan province, iran. for data sampling (2012), l...

OBJECTIVE Percent fat is often considered the reference for establishing the magnitude of adipose tissue accumulation and the risk of excess adiposity. However, the increasing recognition of a strong link between central adiposity and metabolic disturbances led us to test whether waist circumference (WC) is more highly correlated with metabolic syndrome components than percent fat and other rel...

Recent reports have suggested that very early excision (less than 24 hours post-burn) and primary closure of burn wounds might circumvent the immunosuppression which follows severe thermal trauma. The total body surface are (TBSA) involved in burn injuries of human subjects at risk for significant post-burn immunosuppression is large enough to require grafting. In the present study cell-mediate...

Some patients with aortic regurgitation develop irreversible left ventricular dysfunction. The purpose of this study was to noninvasively examine left ventricular function in patients with aortic regurgitation by determining the end-systolic stress-shortening relationship using M-mode echocardiography. Ten normal volunteers and 10 patients with chronic, isolated aortic regurgitation were studie...

in order to study the effect of water deficit stress at different growth stages on yield and seed oil quality of rapeseed cultivars, a field experiment was conducted as split-plot in a randomized complete block design arrangement with three replications in 2009-2010 growing seasons in abarkouh in iran. four levels of irrigation were located in the main plot including, (i1) normal irrigation bas...

conclusions our results indicated that the dissemination of pi-1 was widespread in s. pneumoniae isolates, although no pi-2 isolates were detected. furthermore, the frequency of rlra and rrgc of clinical isolates was significantly more than that of normal flora isolates. results the results confirmed the presence of rlra and rrgc genes in both clinical (n = 39) and normal flora (n = 26) isolate...

to investigate the effects of deficit irrigation and different levels of nitrogen fertilizer on somequantitative and qualitative properties of melissa, a pot experiment was conducted for one year (2011) inmazandaran province. experiment was carried out as a factorial based on randomized complete blockdesign with three replications. irrigation treatments (25, 52 and 75 percent field capacity, fc...
