A long chain insect pheromone for subterranean termites, LC (Lignoceric Acid), was intercalated into the inorganic interlayer, ZLH (Zinc Layered Hydroxide), resulting in the formation of a new nanohybrid, labelled as LCN (Lignocerate Nanohybrid). The formation of this inorganic-organic structure nanohybrid was synthesized by the co-precipitation method using ZnO (Zinc Oxide) as the starting material. The PXRD (Powder X-Ray Diffraction) results confirmed the intercalation process although the diffraction patterns of the resultant nanohybrid and the unbound pheromone were fairly similar but both have different basal spacings values. The FTIR (Fourier Transform Infrared) profiles and the chemical composition test supported the intercalation process with the percentage loading of LC into ZLH calculated to be 85%. The thermal stability of the free anion, LC was enhanced when it was transformed into LCN, increasing from 257 °C to 352 °C. The release of LC from the nanohybrid behaved in a sustained manner, governed by the pseudo-second order kinetic model with higher release of LC in sodium carbonate solution than the pH aqueous media. The synthesized nanohybrid was found to be safe for plant germination when the two seed types were successfully germinated in all the tested nanohybrid concentrations. However, the percentage seed germination and the radical seed length from the nanohybrid showed lower values compared to its counterpart anion, LC.

New World Health Organization guidelines recommend the initiation of antiretroviral treatment(ART) for asymptomatic patients with CD4+ T-cell counts of ≤ 500 cells/mm3. Substantial reduction of human immunodeficiency virus(HIV) transmission is addressed as a major public health outcome of this new approach. Middle East and North Africa(MENA), known as the area of controversies in terms of availability of comprehensive data, has shown concentrated epidemics among most of it's at risk population groups. Serious challenges impede the applicability of new guidelines in the MENA Region. Insufficient resources restrict ART coverage to less than 14%, while only one fourth of the countries had reportable data on patients' CD4 counts at the time of diagnosis. Clinical guidelines need to be significantly modified to reach practical utility, and surveillance systems have not yet been developed in many countries of MENA. Based on available evidence in several countries people who inject drugs and men who have sex with men are increasingly vulnerable to HIV and viral hepatitis, while their sexual partners- either female sex workers or women in monogamous relationships with high-risk men- are potential bridging populations that are not appropriately addressed by regional programs. Research to monitor the response to ART among the mentioned groups are seriously lacking, while drug resistant HIV strains and limited information on adherence patterns to treatment regimens require urgent recognition by health policymakers. Commitment to defined goals in the fight against HIV, development of innovative methods to improve registration and reporting systems, monitoring and evaluation of current programs followed by costeffective modifications are proposed as effective steps to be acknowledged by National AIDS Programs of the countries of MENA Region.

作者： Alfredo H.Saab ahmad Ayar Maxim公司

执行和感应系统有时候包含了电阻性负载,且不管电阻值为何,皆需要一个可控制且定功率的驱动。如果电阻值随着操作情况改变,且可能也会随着最近操作纪录做更改,那么简单的供给电压或电流控制和稳定便不足以确保定功率的输出。

利用单Jaynes-Cummings(J-C)二能级原子和孤立原子构成的模型,研究了该模型中的各种量子关联。基于Dakic等提出的几何量子失协的度量方法,采用数值计算方法分析了系统中两原子间几何量子失协的演化,同时给出了量子纠缠和量子失协的演化。研究结果表明:通过提高两原子间初始纠缠度及处于W态时的纯度可以提高系统的量子关联。耦合常数和光子数在量子关联演化过程中扮演了重要角色。
