In this study, two different non-ionic surfactants have been evaluated as a plasticizer in lithium polymer electrolytes and compared with an organic carbonate-based plasticizer. To that end, molecular weight structure selected (Triton� X-100 Brij�L23) carbonates (EC:DEC1:1) plasticizers electrolytes. The effect of the content, salt content surfactant characteristics on properties such ionic con...
شته جالیز، aphis gossypii glover (hom.: aphididae)، یکی ازآفات مهم گوجه فرنگی در مزارع و گلخانه ها می باشد. میزان خسارت این آفت در گلخانه ها بعد از سفید بالک گلخانه در مرتبه دوم اهمیت قرار دارد. در این تحقیق مقاومت نه رقم از ارقام رایج گوجه فرنگی شامل strian، caligen، super bita، super strian، super af1، has2274، gs-12-f1، sun-6200 f1 و calj نسبت به شته جالیز در شرایط گلخانه ای ارزیابی شد. آز...
High performance concrete (HPC) has several advantages in building construction that cannot be achieved using conventional terms of strength durability, resistance to chemical attack, and workability high are high. The introduction fillers additives contributed the improvement high-performance (HPC), other parameters also influence these HPCs, coarse aggregate fraction is known strongly both fr...
esters of phthalates, mainly applied as plasticizer, cause several human health and environment hazards. phthalates are widely used in pharmaceutical products, cosmetics, as well as other plastic commercial products, and can penetrate in foods, water dusts, and air leading to ingestion and inhalation exposure followed by skin absorption for human. these compounds cause serious adverse effect...
introduction:packaging is an important factor in food industry and is dominated by petroleum-derived polymers. therefore, the amount of research involving the production and characterization of biodegradable films has increased substantially, mainly due to interest in minimizing the ecological impact caused by the use of synthetic packaging materials. several biopolymers have been exploited to ...
trichomoniasis, the most widespread sexually transmitted disease is caused by trichomonas vaginalis. this parasite is site specific for the genitourinary tract and recruitment of macrophages as well as polymorphonuclear nutrophils (pmn) to the site of infection is the first line of defense as a component of non-specific resistance and immunity. in this study, balb/c mice were infected with 10 i...
Experimental Investigation on Bagasse ash Based Geopolymer Concrete Subjected to Elevated Tempreture
Abstract Geopolymer in recent years is being deemed as a promising alternative to cement concrete, which has remained backbone of the construction industry. Despite GPC having potential capability reducing carbon footprint, still many its characteristics and mechanism be investigated. The present study represents utilization bagasse ash production geopolymer concrete. In order reduce ecological...
