BACKGROUND The characteristics of tissue conditioners support microorganism development that can threaten the health of the dentures user. PURPOSE The object of this study was to evaluate the effect on antimicrobial activity, roughness and wettability surface of a tissue conditioners material combined with the antimicrobial polymer poly (2-tert-butilaminoethyl) methacrylate (PTBAEMA). MATER...

The use of chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) has been widely restricted. They have been replaced with hydrofluorocarbons (HFCs) in order to protect the ozone layer. However, the leakage of refrigerant into the air from active or end-of-life air conditioners is a serious environmental issue owing to the high global warming potential (GWP) of HFCs. Therefore, replaci...

Many studies have confirmed positive effect of biochar as a soil conditioner that can increase in short time the amount organic matter (SO) and reserves carbon (OC) soil. The use also contributes to eliminating effects fatigue, especially perennial fruit crops. In our study, was applied spring 2014 cultivation one-year-old peach trees cultivar Meredith. Biochar, an fertilizer, microbiologically...

Poly-γ-glutamic acid (γ-PGA) is an environment-friendly super absorbent polymer that can be used as a soil conditioner, which promising to improve crop productivity and cope with degradation. The objectives of this study are the effects γ-PGA on physicochemical properties winter wheat (Triticum aestivum L. cv. Xinong 975) production in arid region Northwest China. According mass ratio soil, exp...

Dry direct seeding cultivation technology of rice is an important aspect production and management. Six treatments were designed in this paper, that is, T1 (conventional irrigation), T2 irrigation + conditioner), T3 (30% water-saving T4 T5 (50% T6 conditioner). The results showed the three separate treatments, 30% was conducive to growth dry at tillering stage, jointing booting 50% more grain f...

Agricultural production in sodic soil may be hindered by its unfavorable physicochemical properties. In order to find effective measure improve the health of and make it favourable for crop production, a field experiment was conducted at ZARS VC Farm Mandya study effect different amendments on properties soil. The laid under split plot design with inorganic nutrient management viz., RDF, SSNM S...

The aim of the research was to assess effect slurry and soil conditioners on Phleum pratense yield its selected parameters nutrients. second aspect experiment obtain information whether applied together will increase accumulation nitrogen, phosphorus potassium in compared own or with NPK fertilizers. carried out basis a three-year (2015–2017) field experiment. interaction mineral fertilizers te...

The problem of household waste management is becoming more and acute with the growth economic development that country Morocco has experienced. Moreover, this a burden for municipalities, in view its cost, which increasing time. Therefore, work we present design, mechanical photovoltaic study new autonomous solar composter intended mainly households. It allows to transform organic situ, into go...
