Limbah pertambangan adalah hasil buangan dari limbah industri yang disebut sebagai tailing. Tailing berasal batuan berharga diproses menjadi partikel halus dan kemudian dipisahkan antara mineral sisanya. Pada umumnya tailing sangat miskin bahan organik, tidak mengandung unsur hara, porositas tinggi ada aktivitas mikroorganisme. Jumlah terlalu dalam tanah dapat mengganggu perkembangan tumbuhan k...

Two fused-silica capillaries of considerably different inner diameter (75 and 10 microm) were used for the separation of a set of five standard proteins. The separations were run in acid pH (50 mM phosphate buffer, pH 2.5). Generally better separations (with minor tailing only) were obtained using a standard capillary [27 cm (20 cm effective length)x 75 microm I.D.] in comparison with a narrow ...

The thermal inactivation kinetics of Salmonella enteritidis PT4 between 49 and 60 degrees C were investigated. Using procedures designed to eliminate methodological artifacts, we found that the death kinetics deviated from the accepted model of first-order inactivation. When we used high-density stationary-phase populations and sensitive enumeration, the survivor curves at 60 degrees C were rep...

"adipocere" we only find one publication which speaks of this change being observed in a warm country, i.e., " Eight cases of Saponification " by S. C. Mackenzie (.Indian Medical Gazette, 1889, XXIV, p. 42). The author was Police Surgeon at Calcutta, and claimed that during 9 years lie observed 8 cases of adipocere-formation in bodies of persons drowned in the Hooghlj^, or buried in damp soil. ...

A quantized controller is a model-free controller which can provide a nonlinear control. This paper conduct a preliminary study on using the quantized controller in the Static VAR Compensators (SVC) control to enhance the damping of the power-swing. The test system used is a two area multi-machine system. A severe disturbance is introduced into the power system and the quantized controller cont...

Ammonium ions stimulated the formation of the phi diameter 29 protein p3-dAMP initiation complex by decreasing the Km value for dATP in a purified system containing the viral terminal protein p3, the viral DNA polymerase p2, and the phi 29 DNA-protein p3 complex as a template. In addition, NH4+ ions stimulated the amount of p3-dAMP complex elongation and increased by about twofold the rate of e...

1Permanent address: P..O. Box 677, Nedlands, Western Australia, 6009. Despite major recent advances in PCRbased methodology, characterization of the extreme terminal sequences of RNA molecules may be difficult and time consuming, particularly when the 3' end is not polyadenylated.~l~ The usual approach to defining the 5' end involves cDNA synthesis using gene-specific downstream priming of the ...

Abstract: Aim The aim of the present study was to evaluate potential soluble reactive phosphorus (SRP) sorption three natural P adsorbents (Luvisol, Planosol, and Scheelite tailing) from Brazil’s semiarid region. Methods adsorption tests were done under pH 8 conditions with Lanthanum-Modified Bentonite (LMB). effect humic substances on SRP also tested. For this, Luvisol Planosol incinerated red...

The pathogenic networks of immune, vascular, and fibrotic processes underlying non-resolving fibrosis in SSc remain poorly understood. Our previous studies demonstrated that while TLR4 its cognate damage-associated endogenous ligands (DAMPs) elicited potent profibrotic effects myofibroblasts activation, genetic targeting or DAMPs mice accelerated resolution. To prevent aberrant DAMP-TLR4 signal...
