the effect of salting by different salt composition on fatty acid profile studied in hot smoked black and caspian sea sprat, clupeonella cultriventris. after initial prepare activities, samples were exposed to brining process within two salt concentrations including of 100 % nacl (treatment 1 or t1) and 75 % nacl- 25 % kcl (treatment 2 or t2) under 15% brine solution for 3 hrs. the smoking proc...

BACKGROUND Long-chain fatty acids, particularly omega-3 fatty acids found primarily in fish oil, are beneficial in different physiological conditions in the human body. High intake of omega-3 fatty acids has been found to have a strong inverse relationship to sudden cardiac death. An index showing the relationship between different fatty acids in the blood could be an important risk indicator f...

The alkaline depolymerization reaction of poly(ethylene terephthalate) (PET) under quasi-solvent-free conditions was investigated. This is a new approach for recycling PET waste to its monomer building blocks: terephthalic acid and ethylene glycol. influence base particle size, temperature, rotational speed the employed laboratory kneader on yield in quasi-solid-solid depolymerized almost quant...

background and aims. the aim of this study was to compare shear bond strength (sbs) of metal and ceramic brackets bonded to enamel using acid versus er:yag laser etching. materials and methods. eighty premolars were divided into 4 groups: am (acid etching/ metal brackets), ac (acid etching/ ceramic brackets), lm (laser etching/ metal brackets) and lc (laser etching/ ceramic brackets). enamel co...

Potential health effects of drinking water quality changes caused by acid precipitation are presented. Several different types of water supply are discussed and their roles in modifying acid rain impacts on drinking water are explained. Sources of metals contamination in surface water supplies are enumerated. The authors present some results from their research into acid rain impacts on roof-ca...

Background: Obesity in children is now an increasing health risk worldwide in which the insulin-resistance can be present. Studies have linked a diet rich in n-3 fatty acids with a lower prevalence of insulin-resistance. Objective: To compare the levels of eicosapentaenoic acid among obese children with and without insulin-resistance. Materials and Methods: In 56 randomly school-age children wi...

to study the effects of drought stress and foliar application with salicylic acid on yield andit’s components and percentage of essential oil of nigella sativa l., a field experiment was conducted as split plot based on randomized complete block design with three replications at research farm of shahid bahonar university of kerman during growing season of 2013- 2014. the main factor was drought...
