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...

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 ...

BACKGROUND AND METHODOLOGY UK regulations on managing fetal tissue after pregnancy loss, including abortion, are underscored by the concept of 'sensitive disposal'. This involves offering women burial or cremation and, when disposal is by the health care provider, separating fetal tissue from other clinical waste before incineration. We interviewed 23 women who had undergone one or more abortio...

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...

We propose that incidental disgust (i.e. disgust triggered by a factor unrelated to the decision at hand) can influence the choice between two commodities, even when decision makers are unaware of the influence. Two experiments tested the hypothesis that decision makers exposed to an incidental disgust prime (as opposed to a neutral prime) would be more likely to dispose of a status-quo object ...

This study uses depth interviews with mothers about their disposal of children’s possessions to craft a new understanding of the role of identity in disposal. Our study asks: How does identity influence the disposal process of ordinary possessions? A disposal identity continuum of keepers and discarders emerged from the data. This new understanding suggests that disposal involves decisions rega...

Strain LSJC7, with dual resistance to arsenic and tetracycline, was isolated from an antimony tailing in China. Its 16S rRNA gene sequence has the highest similarity to that of Enterobacter cloacae subsp. dissolvens LMG 2683(T) (97.02%). Here we present the approximately 4.6-Mbp draft genome sequence of strain LSJC7.
