We show that Hall-like current can be induced by acoustic phonons in a nondegenerate, semiconductor fluorine-doped single-walled carbon nanotube (FSWCNT) using a tractable analytical approach in the hypersound regime ?(q is the modulus of the acoustic wavevector and is the electron mean free path). We observed a strong dependence of the Hall-like current on the magnetic field, H, the acoustic wave frequency, , the temperature, T, the overlapping integral, , and the acoustic wavenumber, q. Qualitatively, the Hall-like current exists even if the relaxation time does not depend on the carrier energy but has a strong spatial dispersion, and gives different results compared to that obtained in bulk semiconductors. For and , the Hall-like current is in the absence of an electric field and in the presence of an electric field at 300 K. Similarly, the surface electric field due to the Hall-like current is in the absence of an external electric field. In the presence of an external electric field, and for at 300 K. q and can be used to tune the Hall-like current and of the FSWCNT. This offers the potential for room temperature application as an acoustic switch or transistor, as well as a material for ultrasound current source density imaging (UCSDI) and AE hydrophone device in biomedical engineering.

It is estimated that between 0.3% - 0.5% of patients with cholelithiasis have biliary ileus, of this small proportion, only between 1% - 3% is complicated by the syndrome described in 1896 by Leon Bouveret. Bouveret syndrome refers to the obstruction of the gastric outlet tract secondary to the passage and impactation of a gallstone in the duodenum, through a cholecystoduodenal fistula. It is most common in women, between the ages of 74 - 77 and is clinically characterized by pain, bloating, incoercible vomiting and anorexia.

Thermal denaturation and stability of two commercially available preparations of Human Serum Albumin (HSA), differing in their advertised level of purity, were investigated by differential scanning calorimetry (DSC). These protein samples were 99% pure HSA (termed HSA99) and 96% pure HSA (termed HSA96). According to the supplier, the 3% difference in purity between HSA96 and HSA99 is primarily attributed to the presence of globulins and fatty acids. our primary aim was to investigate the utility of DSC in discerning changes in HSA that occur when the protein is specifically adducted, and determine how adduct formation manifests itself in HSA denaturation curves, or thermograms, measured by DSC. Effects of site specific covalent attachment of biotin (the adduct) on the thermodynamic stability of HSA were investigated. Each of the HSA preparations was modified by biotinylation targeting a single site, or multiple sites on the protein structure. Thermograms of both modified and unmodified HSA samples successfully demonstrated the ability of DSC to clearly discern the two HSA preparations and the presence or absence of covalent modifications. DSC thermogram analysis also provided thermodynamic characterization of the different HSA samples of the study, which provided insight into how the two forms of HSA respond to covalent modification with biotin. Consistent with published studies [1] HSA96, the preparation with contaminants that contain globulins and fatty acids seems to be comprised of two forms, HSA96-L and HSA96-H, with HSA96-L more stable than HSA99. The effect of multisite biotinylation is to stabilize HSA96-L and destabilize HSA96-H. Thermodynamic analysis suggests that the binding of ligands comprising the fatty acid and globulin-like contaminant contributes approximately 6.7 kcal/mol to the stability HSA96-L.

许多似乎是无法解释的地质灾变事件对我们的地球和生物圈有着重大的影响.令人疑惑的是这些灾变事件往往同时发生.通过现代银河系天文学的计算,本文试图运用密度波理论来对此加以解释.通过对旋臂引力场内的能量转移计算,我们获知了撞击事件对于太阳,地球,月球的不同程度的影响.其中,我们发现引力撞击时地球能量存在净损失,并且地球与小星体发生撞击的概率会显著升高.巧合的是,每次太阳系绕过银河系旋臂都对应于一次撞击事件.由此,银河系对日地系统所产生的影响能为地质灾变事件提供可能的解释.

Ciprofloxacin (CFX) was loaded on Bana clay (Cameroon) and CFX loaded-clays have been evaluated as drug delivery system. Raw clays and CFX loaded compounds have been characterized by some physico-chemicals methods. In vitro release studies have been done in gastric and phosphate buffer experimental mediums;bacteriological studies have been made up on Escherichia coli and Staphylococcus aureus. X-ray diffractometry patterns of loaded compounds show a basal spacing increasing due to CFX intercalation. on Fourier-Transformed Infrared spectrometry spectra, appearance of CFX characteristic bands and shifting of certain bands already presents on clay confirmed CFX intercalation. After 96 h of CFX released from release mediums, prolonged and continue profiles have been observed. Diffusion tests displayed an inhibition radius of ~2 cm on gelose seeded with Escherichia coli and Staphylococcus aureus due to CFX. The overall results show a modified release of ciprofloxacin with an effective antibacterial activity, giving the way for a new ciprofloxacin drug delivery system using Bana clay as carrier.
