فوم بیوسرامیکی به عنوان داربست، ساختار متخلخلی است که وقتی در بخش آسیب دیده کاشته می شود سلولهای استخوانی باید بتوانند به درون آن پیشروی و رشد کنند تا رفتاری مشابه بافت استخوانی از خود نشان دهند. در این پژوهش، قطعات آپاتیتی برای کاربرد به عنوان ماده زیستی با استفاده از روش ریخته گری ژل ساخته شدند. از پودر هیدروکسی آپاتیت سنتز شده به روش شیمی تر به عنوان ماده سرامیکی اصلی و از آگاروز به عنوان ما...

Casting failures of alloys in dental technology should be the exception, not the rule. They have to be detected in time and associated with possible causes. For the experimental part base metal alloys single tooth restorations were achieved using the conventional lost wax process for casting in order to be evaluated. Some casting defects obtained during the experimental part are exemplified: in...

Neurabin and spinophilin are homologous protein phosphatase 1 and actin binding proteins that regulate dendritic spine function. A yeast two-hybrid analysis using the coiled-coil domain of neurabin revealed an interaction with Lfc, a Rho GEF. Lfc was highly expressed in brain, where it interacted with either neurabin or spinophilin. In neurons, Lfc was largely found in the shaft of dendrites in...

Rho GTPases regulate reorganization of actin and microtubule cytoskeletal structures during both interphase and mitosis. The timing and subcellular compartment in which Rho GTPases are activated is controlled by the large family of Rho GTP exchange factors (RhoGEFs). Here, we show that the microtubule-associated RhoGEF Lfc is required for the formation of the mitotic spindle during prophase/pro...

Processing and storage (4 ± 1°C) quality of Low-fat buffalo mozzarella cheese (BMC) was evaluated with carboxymethyl cellulose (CMC) as fat replacer. Five treatments of BMC viz. Control full-fat cheese (6.0% milk fat; CFFC), Control low-fat cheese (<0.5% MF) without CMC (CLFC), Low-fat cheese with 0.2% CMC (LFC-1), 0.4% CMC (LFC-2) and 0.6% CMC (LFC-3) were comparatively evaluated. Melting time...

This study investigates the heat transfer performance of a novel ZA27 metal foam exchanger. An open-celled is combined with thin-walled copper tube in single-step casting process. The between two separated water streams flowing through and foam, respectively, measured compared to an equivalent shell exchanger arrangement. Heat enhancement up 71% rate exceeding 30 kW are observed attributed incr...

A new Multi-Stage Fuzzy (MSF) controller based on Multi-objective Harmony Search Algorithm (MOHSA) is proposed in this paper to solve the Load Frequency Control (LFC) problem of power systems in deregulated environment. LFC problem are caused by load perturbations, which continuously disturb the normal operation of power system. The objectives of LFC are to mini small size the transient deviati...

In this study, the elevated temperature flexural strengths of lightweight foamed concrete (LFC) containing fly ash (FA) and polypropylene fiber (PF) was investigated experimentally and statistically. The variables included were the temperature degrees (in a range of 20 to 600°C), LFC densities of 600, 800, 1000, 1200 and 1400 kg/m3 and additive content. Two mixes were made by replacing 15% and ...
