به منظور تعیین تأثیر کودهای مرغی و گاوی در پرورش جلبک سبز کلروکوکوم (sp. chlorococcum)، آزمایشی در شش تیمار شامل 1/0، 4/0، 8/0 گرم در لیتر کود مرغی و 1/0، 4/0، 8/0 گرم در لیتر از کود گاوی با سه تکرار در طرح کاملاً تصادفی بهمدت 28 روز اجرا شد. نتایج نشان داد میانگین بالاترین تراکم سلولی (105×1/87 سلول در هر میلیلیتر)، میزان رشد ویژه (054/0 در روز)، بیوماس خشک جلبکی (644/0گرم در لیتر)، کلروفیل ...
Our understanding of phenotypic evolution over macroevolutionary timescales largely relies on the use of stochastic models for the evolution of continuous traits over phylogenies. The two most widely used models, Brownian motion and the Ornstein-Uhlenbeck (OU) process, differ in that the latter includes constraints on the variance that a trait can attain in a clade. The OU model explicitly mode...
The blueberry bud mite (BBM), Acalitus vaccinii (Keifer) , is gaining importance as a pest of southern highbush blueberries. During a BBM population development study in a northcentral Florida location, an epizootic was observed, and the mesothermic acarine mycopathogen, Hirsutella thompsonii (Fisher), was identified as the causal organism. In order to better understand the progression of an ep...
We show that higher derivations on a Hilbert$C^{*}-$module associated with the Cauchy functional equation satisfying generalized Hyers--Ulam stability.
OBJECTIVES Bone replacement substitutes are almost unavoidable in augmentation procedures such as sinus grafting. The objective of the present study was to evaluate the osteoconductive capability of two different scaffold fillers in inducing newly formed bone in this procedure. MATERIAL AND METHODS Sinus floor augmentation and implant placement were carried out bilaterally in 12 patients. Bov...
In this work we study the semi-discrete linearized Benjamin-Bona-Mahony equation (BBM) which is a model for propagation of one-dimensional, unidirectional, small amplitude long waves in non-linear dispersive media. particular, derive stability estimate yields unique continuation property. The proof based on Carleman finite difference approximation Laplace operator with boundary observation larg...
Our aim was to compare the osteogenic potential of mononuclear cells harvested from the iliac crest combined with bovine bone mineral (BBM) (experimental group) with that of autogenous cancellous bone alone (control group). We studied bilateral augmentations of the sinus floor in 6 adult sheep. BBM and mononuclear cells (MNC) were mixed and placed into one side and autogenous bone in the other ...
in this study, scour of mashkid bridge pier located in mashkid river of saravan county has been studied and to measure the scour rate, the numerical model hec-ras 4.0 has been used. upon selection of mashkid river as the case study and whereas the studied zone is important with respect to the climatic conditions and showery monsoon raining and flowing the great and destructive floodwaters, ther...
