Biopiling is an ex situ bioremediation technology that has been extensively used for remediating a wide range of petrochemical contaminants in soils. Biopiling involves the assembling of contaminated soils into piles and stimulating the biodegrading activity of microbial populations by creating near optimum growth conditions. Phytoremediation is another very successful bioremediation technique ...
in this paper, we investigate the zassenhaus conjecture for $psl(4,3)$ and $psl(5,2)$. consequently, we prove that the prime graph question is true for both groups.
آستروسیت ها که عمده ترین سلول های غیر نورونی در مغز می باشند، در پشتیبانی و نگهداری نورون ها نقش دارند. دخالت مسیر پیام رسانی pi3k/akt در ترشح فاکتور محافظ عصبی tgf-? در آستروسیت ها، القا شده با استرادیول، گزارش شده است. در این پایان نامه احتمال شرکت مسیر پیام رسانی canonical wnt در تولید فاکتورهایی از خانواده ی tgf-? نظیر tgf-?و bmp-4 توسط آستروسیت ها بررسی گردید. آستروسیت های جداشده از کورتکس...
The aim of the present study was to evaluate bone formation following maxillary sinus augmentation using bovine bone substitute material Bio-Oss in combination with venous blood by means of histologic and histomorphometric examination of human biopsies. This involved a total of 15 sinus floor elevation procedures being carried out on 11 patients (average age of 49.6 years) according to the tech...
The performances of lubricated systems widely used in natural, biological, and artificial settings are traditionally dictated by their load bearing capacities. Here we unveil that, exploiting a unique coupling between interfacial electro-mechanics, hydrodynamics substrate compliance, it is plausible to realize massive augmentation the capacities ofcompliant microfluidic channels. Our analysis d...
Careful treatment planning, space management, augmentation of bone and attention to the details of implant surgical and prosthetic techniques are important factors when treating anterior maxilla specially replacement of missing teeth. This case report addresses a chair-side ridge augmentation procedure using autograft bone harvested with trephine drills and placed without using screws and the f...
