The aim of this study is to investigate the effects different rates N, Mg and Fe applications on mineral content parsley leaves. experiment was carried out in a greenhouse according randomized plot design with three replications. Seven dose treatments were designed as 130, 160, 190, 220, 250, 280 310 kg per ha N ammonium nitrate (33% N), 40, 80, 120, 200, 240 magnesium sulphate (16% MgO) 8, 16,...
This study presents a novel technology, termed thermomorphic hydrophilicity base-induced precipitation (THBIP), for the effective removal of hardness ions from hypersaline brines with high-scaling propensity. THBIP utilizes thermoresponsive amine bases controlled scaling constituents in alkaline conditions and subsequently uses low-temperature heat to trigger phase separation aqueous solution, ...
Objectives: To evaluate the antimicrobial effects of experimental root canal medicaments on Enterococcus faecalis and Candida albicans day 3 7 using quantitative polymerase chain reaction (Q-PCR) analyses. Materials Methods: 240 single-rooted, single-canalled human teeth were used. Root canals shaped mechanically embedded in acrylic blocks, then sterilized an autoclave. The samples divided into...
Conversion of CO2 into valuable compounds, including fuels, with renewable energy sources and sustainable compounds is a challenge addressed by artificial photosynthesis research. In particular, the application solar assisted electrochemical (EC) processes, in which electrons are furnished photovoltaic (PV) cell, promising approach. A PV-EC system described, consisting CIGS (copper indium galli...
In this study, black peppercorns and cumin seeds were inoculated with a five-serotype cocktail of Salmonella or its surrogate Enterococcus faecium NRRL B-2354. The samples (ca. 107 CFU/g) treated by ClO2 gas at different concentrations (5, 10, 15 mg/L) relative humidities (60, 70, 80%) room temperature (25 °C) five exposure times 120, 180, 240, 300 min). More than 5-log reduction was achieved i...
در اواخر دهه هفتاد میلادی mesri و همکارانش با انجام مطالعات گسترده ای پیرامون نشست درازمدت خاکهای ریزدانه، نظریه خود را مبنی بر ثابت بودن نسبت ضریب تحکیم ثانویه به شاخص تحکیم (ca/cc)ارائه نمودند. مطالعات فراوانی به منظور برابری نتایج آزمایشگاهی و یافته های ساختگاهی با این نظریه صورت گرفته است که تا کنون نیز ادامه دارد. در محدوده بررسی های انجام شده، تاکنون مطالعاتی بر روی خصوصیات تحکیم ثانویه خ...
