    THERMO-HYDRAULICS OF TUBE BANKS WITH POROUS INTERCONNECTORS USING WATER AS COOLING FLUID

    P. V. Ramana, Arunn Narasimhan*, Dhiman Chatterjee

    Frontiers in Heat and Mass Transfer, Vol.3, No.2, pp. 1-6, 2012, DOI:10.5098/hmt.v3.2.3007

    Abstract The present experimental study investigates the effect of tube-to-tube porous interconnectors on the pressure drop and heat transfer (Nu) of tube banks. A copper wire mesh porous medium connects successive tubes of the in-line and staggered arrangement of six rows of tubes. The tubes are subjected to constant and uniform heat flux and cooled by forced convection using water as a cooling fluid in the laminar flow range (100 < ReDuct < 625). The inline configuration with the tube-to-tube porous medium inter-connectors provides marginal enhancement of heat transfer and 12% reduction in the pressure drop More >

    NUMERICAL SIMULATION OF FLUID FLOW AND HEAT TRANSFER IN A MEMS-BASED MICRO CHANNEL HEAT SINK

    Md. Farhad Ismaila,*, M.A.I. Rashidb , M. Mahbubb

    Frontiers in Heat and Mass Transfer, Vol.3, No.3, pp. 1-8, 2012, DOI:10.5098/hmt.v3.3.3002

    Abstract Carbon nanotube (CNT) has been proven to be an effective material for the thermal management of MEMS-based devices due to its superior thermal conductivity. At the same time, micro-channel heat-sinks are widely used in electronic products as a high performance heat transfer device because of its simple construction, easy fabrication process and effective heat removal capability. A numerical study has been carried out to investigate the thermal-fluid characteristics of the aligned and staggered MWCNT (multi walled CNT) based micro pin fins having 650 µm long with hydraulic diameter of ~130 µm.

    EXPERIMENTS ON DOMINANT FORCE REGIMES IN FLOW BOILING USING MINI-TUBES

    Soumei Babaa,*, Nobuo Ohtania, Osamu Kawanamib, Koichi Inouec, Haruhiko Ohtaa

    Frontiers in Heat and Mass Transfer, Vol.3, No.4, pp. 1-8, 2012, DOI:10.5098/hmt.v3.4.3002

    Abstract Effects of tube orientation on flow boiling heat transfer coefficients were investigated for FC72 flowing in single mini-tubes with tube diameters of 0.13 and 0.51 mm to define boundaries on a dominant force regime map. For the tube diameter of 0.51 mm, when mass velocity and vapor quality was varied, heat transfer coefficients were influenced by tube orientation at Froude number Fr < 4, while the effect of tube orientation on heat transfer coefficients disappears at Fr > 4. The results indicated that the boundary between the body force dominated and the inertia dominated regimes was… More >

    Structural analysis of flagellar axonemes from inner arm dynein knockdown strains of Trypanosoma brucei

    RANDI ZUKAS1, ALEX J. CHANG1, MARIAN RICE2, AMY L. SPRINGER1*

    BIOCELL, Vol.36, No.3, pp. 133-142, 2012, DOI:10.32604/biocell.2012.36.133

    Abstract Trypanosoma brucei is a protozoan flagellate that causes African sleeping sickness. Flagellar function in this organism is critical for life cycle progression and pathogenesis, however the regulation of flagellar motility is not well understood. The flagellar axoneme produces a complex beat through the precisely coordinated firing of many proteins, including multiple dynein motors. These motors are found in the inner arm and outer arm complexes. We are studying one of the inner arm dynein motors in the T. brucei flagellum: dynein-f. RNAi knockdown of genes for two components of dynein-f: DNAH10, the α heavy chain,… More >

    Human umbilical artery smooth muscle exhibits a 2-apb- sensitive capacitative contractile response evoked by vasoactive substances and exprsses mrnas for stim, orai and trpc channelsa

    ANA ROCÍO ROLDÁN PALOMO1, PEDRO MARTÍN1, ALEJANDRO REBOLLEDO1*, NICOLÁS ENRIQUE1, LUIS E. FLORES2, VERÓNICA MILESI1

    BIOCELL, Vol.36, No.2, pp. 73-81, 2012, DOI:10.32604/biocell.2012.36.073

    Abstract After depletion of intracellular Ca2+ stores the capacitative response triggers an extracellular Ca2+ influx through store-operated channels (SOCs) which refills these stores. Our objective was to explore if human umbilical artery smooth muscle presented this response and if it was involved in the mechanism of serotonin- and histamine-induced contractions. Intracellular Ca2+ depletion by a Ca2+-free extracellular solution followed by Ca2+ readdition produced a contraction in artery rings which was inhibited by the blocker of Orai and TRPC channels 2-aminoethoxydiphenyl borate (2-APB), suggesting a capacitative response. In presence of 2-APB the magnitude of a second paired contraction by serotonin… More >

    Germination of simojovel pepper seeds (Capsicum annuum L.) previously exposed to NaCl and gibberellic acid

    De la Rosa M1, L Arce1, JA Villarreal1, L Ibarra2, J Lozano3

    Phyton-International Journal of Experimental Botany, Vol.81, pp. 165-168, 2012, DOI:10.32604/phyton.2012.81.165

    Abstract Simojovel pepper seeds were first treated with 0.5 M NaCl, and then put to germinate in solutions of gibberellic acid at different concentrations. Initially, seeds were either preconditioned or not with NaCl combined with 0, 100, 200, 300 or 400 mg/L gibberellic acid. In a second phase of the study, seeds preconditioned with NaCl were exposed to 0, 350, 400, 450 or 500 mg/L gibberellic acid. Experiments were arranged in a completely randomized design with a factorial arrangement of 2 x 5 with four replications. The greatest (p≤0.01) germination percentage (91.75%) was obtained on seeds More >
