Aqueous extraction of gum from flaxseed was optimized using Response Surface Methodology (RSM). In this study the effect of temperature (45-100 °C), pH (3-7) and water/seed ratio (4-24), on the dependent variables including: yield, protein and apparent viscosity of extracted gum were investigated. The results showed that temperature and pH are two major effective factors on yield and quality of...
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
Research Highlights: 1. Soil fungi have a higher influence on seedling density compared to soil environmental factors; 2. Host-specific pathogens and beneficial affect seeding via different influencing mechanisms. Background Objectives: The growth development of seedlings are the key processes that forest regeneration maintain community dynamics. However, factors around their adult conspecifics...
Ultimate pH (pHu) of pork is a major quality determinant. Higher pHu is associated with darker color (Kauffman et al., 1993). A lower pHu is associated with higher drip loss (Kauffman et al., 1993). Pale, soft, exudative (PSE) and red, soft, exudative (RSE) pork is undesirable because it has a low water-holding capacity. At pHu above 5.7, PSE and RSE pork quality problems do not occur (Fernande...
Background and purpose: Sand flies are widespread in Iran and are vectors of leishmaniasis and pappatci fever in most parts of the country including Southern Khorasan Province. Faunistic and ecological studies of these flies are necessary in order to implement proper vector control programs. This research was conducted to determine the sand flies fauna in Southern Khorasan province. Materials ...
Inappropriate feeding habits have been identified as major factors associated with the development of baby bottle tooth decay or nursing caries. An in vivo/in vitro combination technique was developed to investigated the plaque pH changes associated with rinsing with eight different infant formulas. These eight formulas represented four categories: 1) formulas with iron, 2) formulas with low ir...
Fast respiratory rhythms include medium- (MFO) and high-frequency oscillations (HFO), which are much faster than the fundamental breathing rhythm. According to previous studies, HFO is characterized by high coherence (Coh) in phrenic (Ph) nerve activity, thereby providing a means of distinguishing between these two types of oscillations. Changes in Coh between the Ph and hypoglossal (XII) nerve...
