Agriculture plays an important role in the sustainable development of country. Use chemical fertilizers escalate certain components excess quantity thereby deteriorate productivity and leads to unpredicted outcome. This study makes effort reckon accumulation some selected heavy metals [Lead (Pb), Nickel (Ni) Cadmium(Cd)] related indices [bio concentration factor(BCF) translocation factor (TF)] ...
The high level of community activity around the river has resulted in levels heavy metals contained water. Commonly found such as zinc (Zn), mercury (Hg), and copper (Cu). To reduce or remove waters, phytoremediation techniques are used. purpose this study was to determine ability water hyacinth plants (E. crassipes) remediating Zn2+ metal contaminated Lake Tempe research method used includes s...
Background: Distillery’s vinasse wastewater is problematic to be easily disposed of in environment due to its high BOD and COD content which imposes a great deal of costs on plant. The main aim of this scientific and applied research is reducing the organic load of distillery’s vinasse wastewater via concentration technology. Method: In this research, concentration of vinasse technology was...
Introduction: Since the past few decades, the concentration of researches on drug abuse and drugs dependency have shift from risk factor to protective factors. In the past two decades, the concept of resiliency was increasingly considered by developmental psychology. The concentration shifted from risk to resiliency originates from disadvantage in emphasizing on identification of risk factors. ...
the purpose of the present study was to investigate the latent pattern underlying reading ability . some 272 male and female participants. english majors at the ba level , participated in the study. two valid tests were used in this study, the reading test developed exclusively for the purpose of this project and academic reading section of ielts. to investigate the possible latent underlying...
بیان فاکتور رشد اندوتلیال عروق در مایع آمنیوتیک وشکل گیری عروق خونی کیسه ی زرده طی تکوین اولیه جنینی ایجاد رگهای خونی از سلولهای اندوتلیال شامل دو مرحله واسکولوژنز و آنژیوژنز است. واسکولوژنز فرآیندی است که طی آن پیش ساز های سلولهای اندوتلیال عروق ( آنژیوبلاستها) تکثیر و تمایز پیدا می کنند تا رگهای خونی اولیه را شکل دهند. شکل گیری شبکه عروقی یا آنژیوژنز در نتیجه ی جوانه زدن یا منشعب شدن رگه...
Introduction Lead is one of the most important metal ions that has many disadvantages for the environment and organisms, especially humans. One of the most effective methods for causing lead from aqueous solutions is the use of biological adsorbents. The purpose of this study was to investigate the biological biosorption of lead (II) from aqueous solutions using Padina algae. Materials and Met...
In an effort to prevent the formation of pathogenic biofilms on hydroxyapatite (HA)-based clinical devices and surfaces, we present a study evaluating the antimicrobial efficacy of Spherical biogenic Se-Nanostructures Embedded in Organic material (Bio Se-NEMO-S) produced by Bacillus mycoides SelTE01 in comparison with two different chemical selenium nanoparticle (SeNP) classes. These nanomateri...
We experimentally demonstrated photonic crystal microcavity based resonant sensors coupled to photonic crystal waveguides in silicon nano-membrane on insulator for chemical and bio-sensing. Linear L-type microcavities are considered. In contrast to cavities with small mode volumes, but low quality factors for bio-sensing, we showed increasing the length of the microcavity enhances the quality f...
