General Morphological Analysis (GMA) is a method for structuring a conceptual problem space – called a morphospace – and, through a process of existential combinatorics, synthesising a solution space. As such, it is a basic modelling method, on a par with other scientific modelling methods including System Dynamics Modelling, Bayesian Networks and various types graph-based “influence diagrams”....
Lennard-Jones-Devonshire equation of state is an old but theoretical based EOS. The concept of the nearest neighboring molecules or coordination number is proposed to be a function of temperature and volume, whereas it is a constant in the original. The dilute gas and hard sphere limits of molecules are employed to determine this function. Improvement of this modification is demonstrated by pro...
در این پروژه ابتدا اصلاحاتی روی کربوکسی متیل سلولز(cmc) با استفاده ازآغازگرسریک آمونیوم نیترات (can) و گلایسیدیل متاکریلات (gma) صورت گرفت . cmc اصلاح شده (cmc-g-gma) طی واکنش کوپلیمریزاسیون با کایتوسان (chitosan) به کوپلیمر (chitosan-co-cmc-g-gma) تبدیل شد. درمرحل? بعدی طی همین عملیات نانوسلولز(nc) به نانوسلولز اصلاح شده (nc-g-gma) تبدیل گشته و واکنش کوپلیمریزاسیون بین نانوسلولز اصلاح شده با ک...
اخیراً مطالعه ی سیال های محدود شده در نانو حفره ها سطح وسیعی از تحقیقات تجربی، نظری و شبیه سازی های رایانه ای را به خود اختصاص داده است. می دانیم که توزیع سیال در مجاورت یک دیواره ی جامد ناهمگن است و خواص چنین سیالی اساساً متفاوت از سیال ماکروسکوپی است. نتایج این تحقیق که مبتنی بر محاسبات نظریه ی تابعی چگالی است. نشان مر دهد که توزیع ناهمگن سیال در نانو حفره ها و همچنین بروز خواص متفاوت این سیالا...
R-GMA (Relational Grid Monitoring Architecture) [1] is a grid monitoring and information system that provides a global view of data distributed across a grid system. R-GMA creates the impression of a single centralised repository of information, but in reality the information can be stored at many different locations on the grid. The Registry and Schema are key components of R-GMA. The Registry...
In a study aimed to test the effect of body position on the parameters derived from surface electrogastrograms, 17 healthy volunteers (2M, 15F; median age 22.5 years) attended in random order two examination sessions held on separate days. A 30-min recording of the interdigestive gastric myoelectrical activity (GMA) was followed by a 90-min postprandial recording after intake of a 394 kcal mixe...
With the aim of reducing human exposure to Bisphenol A (BPA) derivatives in dentistry, a fluorinated dimethacrylate monomer was synthesized to replace 2,2-bis[4-(2-hydroxy-3-methacryloy-loxypropyl)-phenyl]propane (Bis-GMA) as the base monomer of dental resin. After mixing with reactive diluent triethyleneglycol dimethacrylate (TEGDMA), fluorinated dimethacrylate (FDMA)/TEGDMA was prepared and c...
Plastic embedding preserves tissue structure much more faithfully than does paraffin. Acrylic polymerization is innocuous to dye-binding groups in sections. The water solubility of glycol methacrylate monomer and the hydrophilic properties of the polymer allow for convenience in dehydration and for versatility in staining sections. Five years of experience with glycol methacrylate (GMA) embeddi...
In this paper, we have obtained and presented new relativistic stellar configurations considering an anisotropic fluid distribution with a charge distribution and a gravitational potential Z(x) that depends on an adjustable parameter. The quadratic equation of state based on Feroze and Siddiqui viewpoint is used for the matter distribution. The new solutions can be written in terms of elementar...
