Performance of carbon nanotube(CNT) and their attached metal oxides(manganese oxide(MnO) and cadmium dioxide(CdO2)) structures as anode electrodes in lithium-ion battery(LIB) and potassium-ion battery(KIB) are investigated. The Gibbs free energy of adsorption of Li and K atoms/ions on surfaces of CNT(8, 0), CNT(8, 0)-MnO and CNT(8, 0)-CdO2 are calculated. The cell voltages(Vcell) of Li and K atoms/ions adsorption on studied surfaces are examined. The Vcell of LIBs with metal-oxides attached to CNT(8, 0) as anode electrodes are higher than those KIBs. The adsorbed metal oxides(MnO and CdO2) on CNT(8, 0) increased the charges, electronic conductivity and Vcell of LIB and KIB, efficiently. The CNT(8, 0)-CdO2 as anode electrodes in LIB and KIB is proposed.

Cupping therapy has been widely used for clinical treatment of soft tissue lesions. The current study investigated the effects of cupping therapy on biomechanical properties of the skin in Wistar rats. 20 rats were divided into two groups: 10 in experimental and 10 in control group. Either the right or the left lower quadrants of the lumbar regions in the experimental group underwent 10 minutes daily cupping therapy for 12 days. The skin stiffness and ultimate tensile strength of all the rats were measured using tensiometer. The skin stiffness and ultimate tensile strength were decreased significantly in cupping side of the experimental group as compared with the non-cupping side and the control group. There were no significant differences between the non-cupping side of the experimental group and the control group. In conclusion, cupping therapy can be useful as a treatment method to reduce the skin stiffness and ultimate tensile strength.

Slow and fast light processes, based on both structural and material dispersions, are realized in a wide tuning range in this article. Coherent population oscillations （CPO） in electrically tunable quantum dot semiconductor optical amplifiers lead to a variable group index ranging from the background index （nbgd） to^30. A photonic crystal waveguide is then dispersion engineered and a group index of 260 with the normalized delay-bandwidth product （NDBP） of 0.65 is achieved in the proposed waveguide. Using comprehensive numerical simulations, we show that a considerable enhancement of slow light effect can be achieved by combining both the material and the structural dispersions in the proposed active QDPCW structure. We compare our developed FDTD results with analytical results and show that there is good agreement between the results, which demonstrates that the proposed electrically-tunable slow light idea is obtainable in the QDPCW structure. We achieve a total group index in a wide tuning range from nbgd to^1500 at the operation bandwidth, which shows a significant enhancement compared with the schemes based only on material or structural dispersions. The tuning range and also NDBP of the slow light scheme are much larger than those of the electrically tunable CPO process.

Sand production is one of the major problems in sandstone reservoirs. Different mechanical and chemical methods have been proposed to control sand production. In this paper, we propose a chemical method based on using polyacrylamide/chromium triacetate hydrogel to investigate sand production in a synthetic sandpack system. To this end, a series of bulk experiments including the bottle test and rheological analysis along with compression tests were conducted. Experimental results indicated that the compressive strength of the sandpack was increased as much as 30 times by injecting 0.5 pore volume of hydrogel. Also, it was found that the increases in cross-linker and polymer concentrations exhibited a positive impact on the compressive strength of the sandpack, mostly by cross-linker concentration(48 psi). Hydrogel with a higher value of cross-linker could retain its viscoelastic properties against the strain which was a maximum of 122% for 0.5 weight ratio of cross-linker/polymer. The presence of salts, in particular divalent cations, has a detrimental effect on the hydrogel stability. The maximum strain value applied on hydrogel in the presence of CaCl_2 was only about 201% as compared to 1010% in the presence of distilled water. Finally, thermogravimetric analysis and its derivative showed that the hydrogel could retain its structure up to 300 °C. The results of this study revealed the potential application of the hydrogel to control sand production.

Objective: To survey the level and patterns of reverse transcriptase-based drug resistance and subtype distribution among antiretroviral-treated HIV-infected patients receiving only reverse transcriptase inhibitors in ***: A total of 25 samples of antiretroviral therapy experienced patients with no history of using protease inhibitors were collected. After RNA extraction, reverse transcriptase-nested PCR was performed. The final products were sequenced and then analysed for drug-resistant mutations and ***: No drug resistant mutations were observed among the 25 subjects. The results showed the following subtypes among patients: CRF 35_AD(88%), CRF 28_BF(8%),and CRF 29_BF(4%).Conclusions: A significant increase in drug resistance has been noted in recentlyinfected patients worldwide. Subtype distributions are needed to perform properlydesigned surveillance studies to continuously monitor rates and patterns of transmitted drug resistance and subtypes to help guide therapeutic approaches and limit transmission of these variants.
