COVID-19 and Respiratory Protection for Healthcare Providers
(Nofer Inst Occupational Medicine, Sw, 2021)
This article has investigated the considerations of healthcare facilities to utilize reusable respirators as an alternative to disposable respirators during the COVID-19 pandemic. The decision to choose specific equipment ...
Radiation synthesis and characterization of chitosan/hyraluronic acid/hydroxyapatite hydrogels: drug uptake and drug delivery systems
(Elsevier Science Bv, 2018)
In this work, a new chitosan (CS)/hyaluronic acid (HA)/hydroxyapatite (HAP) hydrogels were synthesized by using gamma rays irradiation technique for oral delivery of drugs. The hydrogelss were characterized using fourier ...
Silver Nanoparticles: Ecofriendly Surface Sterilization of Plant Seeds in Different Shapes and Sizes
(Pakistan Agricultural Scientists Forum, 2019)
In this study, silver nanoparticles obtained via green synthesis were utilized for the surface sterilization of seeds in different shapes and sizes. Water extracts of dried Alkanna tinctoria rhizomes and Pinus nigra leaves ...
Preparation and characterization of conducting hydrogels composite made of polyaniline, polyacrylamide and kaolin
(Elsevier Science Bv, 2018)
In this work, clay minerals such as kaolin particles were embedded within the network of poly(acrylamide) hydrogel (PAAm) using free radical solution polymerization method. Aniline monomer was absorbed in the network of ...
Electric Arc Furnaces for Steel-Making: Hot Spots for Persistent Organic Pollutants
(Amer Chemical Soc, 2009)
Persistent organic pollutant (POP) concentrations were measured in stack-gases of ferrous scrap processing steel plants with electric arc furnaces (EAFs) (n = 5) in Aliaga, Izmir, Turkey and in air (n = 11) at a site near ...
Model-based evaluation of microbial mass fractions: effect of absolute anaerobic reaction time on microbial mass fractions
(Taylor & Francis Ltd, 2010)
Although enhanced biological phosphorus removal processes (EBPR) are popular methods for nutrient control, unstable treatment performances of full-scale systems are still not well understood. In this study, the interaction ...
Environmental Toxicity of Cadmium and Health Effect
(Scibulcom Ltd, 2009)
Environmental toxicology examines the fate and effects of contaminants in the environment. Exposures to heavy metals can affect human health both directly or indirectly by disrupting ecological systems that exist in rivers, ...

The contents of fatty acids and other lipids of Trifolium balansae Boiss, Trifolium stellatum Lin., Trifolium nigrescens Viv. subsp. petrisavi (Clem) Holmboe, Trifolium constantinopolitanum Ser., and Trifolium resupinatum ...
Importance of EBPR efficiency on energy demand of full-scale wastewater treatment plants
(Desalination Publ, 2010)
Enhanced biological phosphorus removal processes (EBPR) are one of the most popular methods in nutrient control. Energy demand of wastewater treatment plants (WWTPs) is also very critical actual concern. In this study, ...
Reuse of anaerobically and aerobically pre-treated textile wastewater by UF and NF membranes
(Elsevier, 2010)
The aim of this study is to compare different pre-treatment techniques before the use of UF and NF membranes for textile industry effluents. Three different applications are discussed. First, raw textile wastewater effluent ...
