The effects of two mineral and two organic acids, four organic solvents (methanol, ethanol, 2-propano and acetone) and three inorganic metal salts in combination with temperature regimes 0 and 22C on the yield and resolubility of potato tuber proteins were studied. Using acids, the yield of precipitated protein ranged from 22.3% (citric acid, 0C) to 54.5% (acetic acid, 22C) of total protein; ho...
in this research, the kinetics of carbothermic reduction of molybdenite in the presence of sodium carbonate was studied. For this purpose, mixed powder of molybdenite, graphite, and sodium carbonate with 1:4:2 mole ratio was investigated using simultaneous thermal analysis (STA) at the heating rates of 10, 15 and 20 0C /min. The results of thermal analysis were evaluated through Friedman, Kissi...
The present paper deals with the synthesis of terpolymer films of MMA-STY-AN and their physical properties were studied. The films were translucent, brittle and light yellow in colour. The films were found water permeable. The films were soluble in most of non polar solvents. The softening range of alloy films was found in between 89–119 0C. The specific conductance of terpolymer films was foun...
A powder mixtures of 18.72% wt, 17.67% wt Al2O3 and 63.6% wt zircon were prepared and milled in a planetary ball milled for one up to 10 hours in presence of air. After removal Iron impurity from as-milled samples, they were isothermally heated in temperature range of 1300-1450 0C for one hour in an air atmosphere. After cooling the samples, they were studied using XRD analyses. The XRD and PSA...
The article presents the results of long-term studies (1982-2018) on assessment changes in thermal resources during growing season and indication their impact yield spring wheat. work was carried out conditions northern part Middle Volga region gray forest soils. soil experimental site is medium loamy, content humus (according to Tyurin) 2.8...3.2%, mobile phosphorus potassium Kirsanov) - 105.....
Thermal properties and chemical performance of newly developed Thevetia peruviana oil-based (TPO) bio-composites with short sisal fibers reinforcement were studied in this research, the aim producing materials derived from renewable resources for engineering applications. Three sets TPO composites (5C, 10C 15C) reinforced 5, 10 15 wt% respectively produced by compression moulding method. Thermo...
Two trawl surveys in the Northeastern Aegean Sea, conducted in 1997 and 2007 yielded a catch composition which, when re-expressed through the new concept of ‘mean temperature of the catch’ (MTC) yielded an MTC increase of 0.25 0C per decade, which is higher of the global MTC increase rate between 1970 and 2006, but slightly lower than the observed temperature increase in the Northeastern Aegean...
Due to the importance of medicinal plants, understanding the seed germination response to temperature is agronomically important. A laboratory study was conducted to investigate the effect of different temperatures on seed germination of fennel, cannabis and sesame in a completely randomized design with four replications. Various constant temperatures (5, 10, 15, 20, 25, 30, 35 and 40°C) we...
A research was conducted on the eff ect of heat treatments on the heating and cooling of the ‘Idared’ apple fruit. Th e heat treatment was performed as hot water dip (HWD), where fruit were dipped into water at 50 °C, for two, four and six minutes (HWD 500C 2’, HWD 500C 4’ and HWD 500C 6’, respectively). Th e aim of the study was to determine the eff ect of heat treatments on the warming and co...
