in this research, the physico-chemical water quality parameters and the effect of climate changes onwater quality is evaluated. during the observation period (5 months) physico-chemical parameterssuch as water temperature, turbidity, saturated oxygen, dissolved oxygen, ph, chlorophyll-a, salinity,conductivity, and concentration of total nitrogen (nutrient level) as main pollutant factor have be...

background: 66ga (t1/2=9.49 h, β+: 4.153 mev, γ: 511, 834, 1039, 2752 kev) has a wide range of applications in different fields of medical sciences. production of 66ga became one of our main interests, according to its increasing applications in nuclear medicine, particularly in pet imaging. materials and methods: 66 zn (p,n)66ga reaction was determined as the best choice for the production of ...

In this study, quantitive characteristics and chemical composition of in roach (Rutilus rutilus caspicus) sperm were investigated. Sperm traits included sperm movement duration, percentage of motile spermatozoa, sperm density, spermatocrit and sperm volume. Some seminal plasma characteristics (sodium, potassium, calcium, magnesium and chloride) were investigated. In addition, some metabolites o...

This study evaluated the ability of fennel extract to improve the quality of refrigerated minced silver carp over a period of 16 days. Minced silver carp were treated with fennel extract (0.5, 1 and 1.5% w/w), and beta-hydroxy toluene (BHT 200 ppm). The control and the treated fish samples were analyzed periodically (every 4 days) by chemical analysis (Peroxide value (PV), thiobarbituric acid (...

background: previous research has shown that cr is needed for growth and protein synthesis. objectives:  this study was carried out to determine the effects of supplementing chromium-methionine (cr-met) on performance, hematologic characteristics and meat quality parameters in kids. methods: thirty-two male kids (average initial bw of 22 ± 2 kg, 4mo) were used in a completely randomized design ...

pasta products are known in all countries of the world and the quality of them are dependent on the technology and type of flour. at the present, these products are producing with wheat flour and old technology, or semolina and modern technology. the goal of this study was the assessment of spaghetti's quality that are producing in iran, for this purpose samples were taken from all factories in...

Drinkability of water is determined based on its physical, chemical, and microbial properties. Undesirable changes in these parameters could threaten the health of consumers. The present study aimed to assess the physical, chemical, and microbial parameters of the drinking water sources in Sanandaj, Iran and compare them with the national standard values. This descriptive, cross-sectional study...
