evaluation of physicochemical and sensory properties of pomegranate juice- milk drink during storage
milk and fruit juice due to the high nutritional value, are widely consumed by society’s people. pomegranate juice in spite of nutritional value has oldness in consumption and milk-pomegranate juice product could be desirable specifically for the consumers who are keen to experience new formulation and taste. milk-juice beverage is a type of acidified milk drink that one of the main problems in...
fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...
the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
magnetic resonance imaging (mri) is a notable medical imaging technique that makes of phenomenon of nuclear magnetic resonance. because of the resolution and the technology being harmless, mri has considered as the most desirable imaging technique in clinical applications. the visual quality of mri plays an important role in accuracy of medical delineations that can be seriously degraded by exi...
We present a strong parallel repetition theorem for the entangled value of multi-player, oneround free games (games where the inputs come from a product distribution). Our result is the first parallel repetition theorem for entangled games involving more than two players. Furthermore, our theorem applies to games where the players are allowed to output (possibly entangled) quantum states as ans...
A Schrödinger cat state is a linear superposition of two quantum states that differ on a macroscopic scale. Whereas superpositions of quantum states are commonplace in the microscopic world, a superposition of macroscopically distinct states is practically never observed. The understanding of why this is so has evolved considerably with the development of the quantum mechanics of dissipative sy...
gender as one of the social and cultural determinant factors, affects many dimensions of women including their occupation and can affect the types of male and female jobs. nowadays, gender segregation of jobs in iran is gradually being removed. nevertheless, social policy making in this subject needs scientific studies. it seems necessary to take advantage of qualitative methods. in this quali...
Introduction Well-defined structures of nanometer-dimensions are subject to intense research efforts. However, a rational control of structure formation on this length scale by convenient versatile means, and the control of functional properties and stability remain key challenges. Recent approaches to the controlled preparation of metal or semiconductor nanoparticles have utilized surfactants ...
We study electronic transport in long DNA chains using the tight-binding approach for a ladder-like model of DNA. We find insulating behavior with localizaton lengths ξ ≈ 25 in units of average base-pair seperation. Furthermore, we observe small, but significant differences between λ-DNA, centromeric DNA, promoter sequences as well as random-ATGC DNA. 1 Introduction DNA is a macro-molecule cons...
