To distinguish between order and disorder is of fundamental importance to understanding solids. It becomes more significant with recent observations that solids with high structural order can behave like disordered solids, while properties of disordered solids can approach crystals under certain circumstance. It is then imperative to understand when and how disorder takes effect to deviate the ...

High-solids centrifugation can reduce the cost of managing or disposing of anaerobically digested biosolids. High-solids centrifuges can increase relative cake solids by as much as 5% DS compared with other dewatering devices, such as belt filter presses, with a resulting 15-20% reduction in overall mass of hauled biosolids. Cost reductions can be similar (15-20%) or more, depending on the type...

Stickiness of powder particles is often responsible for their impaired flow characteristics. Stickiness resulted from glass transition showing a relationship with mechanical -relaxations, and stickiness occurred differently in dairy solids modified in their lactose and protein contents. Glass transition, -relaxation and stickiness properties of milk solids systems were related to their solids c...

Agarose beads containing immobilized enzymes or affinity ligands have been made magnetically responsive by adsorbing freshly precipitated magnetite on their surface. These beads are used for affinity adsorption of proteins from complex mixtures containing suspended solids. The magnetically responsive beads and the unwanted (diamagnetic) solids are then separated by magnetic filtration. This mag...

It has been demonstrated that simultaneous exposure of Daphnia magna to suspended solids and a carbamate pesticide potentiates the toxic response to the pesticide. The toxicodynamics between these stressors were investigated to determine possible mechanisms of interaction. Three experimental series were conducted with D. magna to determine: the effect of food availability on carbofuran toxicity...

We present the results of an extensive numerical study of the orbital evolution of small solids, ranging from dust grains to km-sized objects, in the vicinity of a local density enhancement in a non-uniform solar nebula. In a previous study we have shown that when the motions of such solids are restricted to the midplane of the nebula, the combined effect of gas drag and pressure gradients caus...

In order to investigate the effect of different levels of nitrogen and bio-fertilizers on yield of canola plants in Qazvin, Iran, a split-plot design was conducted on the base of randomized complete block design with four replications. Treatments included 3 levels of nitrogen (0, 75 and 150 kg ha-1) and bio-fertilizers on four levels (no inoculation, Azotobacter, Azospirillum and a combination ...

“Pharmaceutical Solids” discusses scientific principles associated with pharmaceutical solids useful to practitioners in validation and compliance. We intend this column to help the understanding of principles associated with pharmaceutical solids and to be a useful resource for daily work applications. Enhanced process understanding is an important objective of the quality-by-design initiative...

objective: this study is an attempt to examine the anti apoptotic effects of bio on rat msc culture. materials and methods: rat marrow primary cell culture was established and exposure groups were defined; cultures with 0.01, 0.1, 1 μm bio. cells cultured without bio treatment were used as controls. during culture expantion, the average doubling time, as an index of the rate of cell growth, wer...

this research set out to evaluate the effect of combined biological and chemical nitrogen fertilizers on some corn hybrids. to this end an experiment was conducted as split plot on the basis of randomized complete block design with four replications. main plots were included: use of chemical and biological fertilizers in four levels: 100% chemical fertilizer, 75% chemical fertilizer + 100% bio-...
