Large body size usually extends dive duration in air-breathing vertebrates. However, the two largest predators on earth, the blue whale (Balaenoptera musculus) and the fin whale (B. physalus), perform short dives for their size. Here, we test the hypothesis that the foraging behavior of these two species (lunge-feeding) is energetically expensive and limits their dive duration. We estimated the...

As the climate warms, species that cannot tolerate changing conditions will only persist if they undergo range shifts. Redistribution ability may be particularly variable for benthic marine species that disperse as pelagic larvae in ocean currents. The blue mussel, Mytilus edulis, has recently experienced a warming-related range contraction in the southeastern USA and may face limitations to no...

Peningkatan aktivitas industri tekstil semakin menambahkan jumlah limbah di lingkungan. Tembaga merupakan salah satu komponen pewarna sintetis sehingga berpeluang mengandung dan tembaga. Bioremediasi menggunakan bakteri indigenus yang resisten terhadap tembaga diharapkan dapat meningkatkan efesiensi pengolahan tekstil. Isolat IrN diisolasi dari limbah. Penelitian ini bertujuan untuk melakukan k...

Before the First World War, almost all dyes were applied from solution in an aqueous dyebath to substrates such as cotton, wool, silk and other natural fibres. However, the introduction of a man-made fibre, cellulose acetate, with its inherent hydrophobic nature, created a situation where very few of the available dyes had affinity for the new fibre. Water-soluble anionic dyes had little substa...

The rheology of disperse systems is an important processing parameter. Being able to characterize and manipulate the flow behavior of dispersions one can ensure their optimal performance. Waterborne automotive coatings, for example, should exhibit a distinct low-shear viscosity necessary to provide good leveling but to avoid sagging at the same time. Then, a strong degree of shear thinning is n...

a bacterial strain (strain ps) was isolated from the textile effluents carrying serilene black bnfs® (c.i. disp. blk. mix) disperse dye. the isolate was able to decolorize the dye without the need for any exogenous carbon source. full sequencing of its 16s rrna indicated that bacillus sp strain ps is related to bacillus cereus groups.  silica- gel-thin layer chromatography of serilene black dye...
