Sistem pendingin pada mesin bakar internal umumnya bertujuan unuk menyerap sebagian panas yang ditimbulkan oleh proses pembakaran di dalam silinder. Dengan penggunaan heat exchanger (HE) suhu dapat stabil dengan cara dibantu cairan melalui radiator diisi coolant untuk membuat efektivitas perpindahan menjadi lebih optimal. Penelitian ini mengetahui pengaruh laju alir fluida terhadap menggunakan ...

SMITN, E. NORBERT. Cutaneous heat fZow during heating and cooZing in Alligator mississipiensis. Am. J. Physiol. 230(S): 12054210. 1976. -Direct in vivo measurement of heat flow across the skin of the American alligator (AlZigator mississipiensis) showed increased heat flow during warming. Mean values at 25OC during warming (15-35°C) in air (airspeed 300 cm/s) were 17.9 t 1.2 SE Cal/cm” per h (m...

Blends of aqueous dispersion of a hydrophobic and hydrophilic polymer, namely Surelease®: hydroxypropyl methylcellulose (Surelease®: HPMC E15) were used as coating materials to control the drug release from coated pellets of the highly water soluble drug metoprolol succinate. Varying the polymer blends, ranges of drug release patterns were obtained at pH 6.8. The present study dealt with diffus...

Methods Fly stocks All crosses were carried out at 25oC under standard conditions. tor mutants were obtained by crossing tor with tor mutants. tor is the strongest constitutively activated tor mutation. pgc null mutant allele corresponds to the P-element insertion EY7794 (Martinho et al., 2004). pgc and tor double mutants stocks were obtained by recombination with tor or tor mutant alleles, and...

In this article CuO/water nanofluid was synthesized by using polyvinylpyrolidone (PVP) as the dispersant.  Thenanofluid stability period and the heat transfer enhancement were determinedby measuring the thermal conductivities. To study the nano-fluid stability, zeta (ζ) potential, and absorbency were measured under different pH values and PVP surfactant concentrations; also thermal conductivity...

This study was aimed to investigate the creep behavior of laminated veneer lumber (LVL) Sengon,especially under application compression and tension stress parallel-to-the-grain. In IndonesiaLVL made from fast-growing Sengon (Paraserianthes falcataria) species is designed be usedas a substitution for solid wood in building construction. Creep test conducted on specimenswith reference ASTM D143‐0...

The ternary blends consisting of Chitosan (CS), Nylon6 (Ny6) and Polyurethane foam (PUF) were prepared by solution blending method. The Structural, thermal and morphological studies were performed by Fourier transform infrared spectroscopy (FTIR), Thermo gravimetric analysis (TGA), X-ray diffraction (XRD) and Scanning electron microscope (SEM). The FTIR results showed intermolecular hydrogen bo...
