In this work we investigated the thermoluminescence proprieties of nanopourous aluminum oxide strips produced by anodic oxidation of aluminum in several solvents in order to obtain a suitable dosemeter for radiation dose measurements. The photoluminescence and infrared characterization were performed at room temperature using a Jobin Yvon Ramanor model U-1000 spectrometer using either a 150 W X...

The design and optimization of a nanostructured antireflective coatings for Si solar cells were performed by using response surface methodology (RSM). RSM was employed to investigate the effect on overall optical performance silicon coated with three different nanoparticle materials titanium dioxide, aluminum oxide, zinc oxide nanostructures. Central composite used reflectance process study mai...

Background  Recent investigations show that both proliferation and secretion of macromolecules by cells can be regulated by low level laser therapy (LLLT). The aim of this study was to determine whether LLLT could induce a bio-stimulatory effects on human gingival fibroblasts (HGF3-PI 53). Therefore, the effect of laser irradiation on human gingival cell proliferation and collagen type I gene ...

One of the most serious effects micropollutants in environment is biological magnification, which causes adverse on humans and ecosystem. Among all micro-pollutants, antibiotics are commonly present aquatic due to their wide use treating or preventing various diseases infections for humans, plants, animals. Therefore, an aluminum-based electrocoagulation unit has been used this study remove cep...

BACKGROUND Thermostable bacterial lipases occupy a place of prominence among biocatalysts owing to their novel, multifold applications and resistance to high temperature and other operational conditions. The capability of lipases to catalyze a variety of novel reactions in both aqueous and nonaqueous media presents a fascinating field for research, creating interest to isolate novel lipase prod...

Efficient time series forecasting (TSF) is of utmost importance in order to make better decision under uncertainty. Over the past few years a large literature has evolved to forecast time series using different artificial neural network (ANN) models because of its several distinguishing characteristics. This paper evaluates the effectiveness of three methods to forecast time series, one carried...

This paper integrates Nelder–Mead simplex search method (NM) with genetic algorithm (GA) and particle swarm optimization (PSO), respectively, in an attempt to locate the global optimal solutions for the nonlinear continuous variable functions mainly focusing on response surface methodology (RSM). Both the hybrid NM–GA and NM–PSO algorithms incorporate concepts from the NM, GA or PSO, which are ...
