We introduce the stochastic Boltzmann equation (SBE) as an approach for exploring the spin dynamics of magnetic molecules coupled to a stochastic environment. The SBE is a time-evolution equation for the probability density of the spin density matrix of the system. This probability density is relevant to experiments which take measurements on single molecules, in which probabilities of observin...

BACKGROUND AND STUDY AIMS Balloon-assisted enteroscopy allows therapeutic intervention in the small bowel, and even of the biliopancreatic system in patients with altered anatomy. However, the conventional single-balloon enteroscope (SBE) has limited therapeutic use because of its small-caliber working channel and the lack of an additional water jet channel. The new single-balloon enteroscope p...

Lipase biosynthesis optimization, Aspergillus niger ADM 110, Gamma radiation Objectives: The present study describes the isolation, identification and screening of fugal isolates for the biosynthesis of extracellular lipase enzyme. Methodology: Thirteen fungal cultures were isolated from cotton seeds, waste cake of cotton seed oil and spent bleaching earth, samples by serial dilution method. Al...

The effect of hypothermic storage on striped bass sperm calcium homeostasis was determined by Fluo-3 flow cytometry. Calcium homeostasis was defined as the ability of cells to maintain a low concentration of intracellular free calcium as measured by Fluo-3 fluorescence. Sperm were stored frozen in striped bass extender (SBE) and Tris-NaCl medium (T350) modified with 50 mM glycine and 7.5% dimet...

Peroxide bleaching is significantly affected by transition and alkaline earth metals. Isolating the effects of different transition and alkaline earth metals on the reactions of peroxide with different representative lignin structures allows the separation of the positive from the negative contributions of these metal ions. In this work, five monomeric or dimeric phenolic lignin model compounds...

Patients with altered anatomy such as a Roux-en-Y anastomosis often present with various pancreaticobiliary problems requiring therapeutic intervention. However, a conventional endoscopic approach to the papilla is very difficult owing to the long afferent limb and acute angle of a Roux-en-Y anastomosis. Balloon-assisted enteroscopy can be used for endoscopic retrograde cholangiopancreatography...

Nanotechnology is the recent science dealing with materials at nano-sized (smaller than 100nm). showed its potential significance in almost all industrial sectors. In current paper, potency of nanotechnology was affirmed food and technology, especially manufacturing edible oils which passes many procedures, from most important step bleaching to remove colorants contaminants enhance quality para...
