With the development of the electric vehicles, serial connected cells have a broad prospect in the future. But the difference of the serial connected cells especially for Li-ion cells is prone to cause a lot of problems, such as overcharge and overdischarge. For these reasons, various cells balancing methods are applied. In this article main balancing methods will be compared, and as a result, the inductive charge transfer method will be adopted to balance the cells due to its obvious advantages. Furthermore, the principle and the realization of this balancing system will also be explained.

We cannot be sure exactly what will happen, we can only estimate by using a particular method, where each method must have the formula to create a regression equation and a formula to calculate the confidence level of the estimated value. This paper conveys a method of estimating the future values, in which the formula for creating a regression equation is based on the assumption that the future value will depend on the difference of the past values divided by a weight factor which corresponding to the time span to the present, and the formula for calculating the level of confidence is to use "the Haryadi Index". The advantage of this method is to remain accurate regardless of the sample size and may ignore the past value that is considered irrelevant.

An allergic reaction to mosquitoes can result in severe or abnormal local or systemic reactions such as anaphylaxis, angioedema, and general urticarial or wheezing. The aim of this review is to provide information on mosquito saliva allergens that can support the production of highly specific recombinant saliva allergens. In particular, candidate allergens of mosquitoes that are well suited to the ecology of mosquitoes that occur mainly in East Asia will be identified and introduced. By doing so, the diagnosis and treatment of patients with severe sensitivity to mosquito allergy will be improved by predicting the characteristics of East Asian mosquito allergy, presenting the future direction of production of recombinant allergens, and understanding the difference between East and West.

Environmental problems such as air pollution and greenhouse gas emissions are especially challenging in urban areas. Electric mobility in different forms may be a solution. While in recent years a major focus was put on private electric vehicles, e-mobility in public transport is already a very well-established and mature technology with a long history. The core objective of this paper is to analyze the economics of e-mobility in the Austrian capital of Vienna and the corresponding impact on the environment. In this paper, the historical developments, policy framework and scenarios for the future development of mobility in Vienna up to 2030 are presented. A major result shows that in an ambitious scenario for the deployment of battery electric vehicles, the total energy demand in road transport can be reduced by about 60% in 2030 compared to 2018. The major conclusion is that the policies, especially subsidies and emission-free zones will have the largest impact on the future development of private and public e-mobility in Vienna. Regarding the environmental performance, the most important is to ensure that a very high share of electricity used for electric mobility is generated from renewable energy sources.

Objectives: There are no regulations governing the practice of acupuncture in Lebanon as it is not yet registered as a profession. To our knowledge, no studies have ever been conducted in Lebanon regarding the practice of acupuncture. The purpose of this preliminary study was to explore the knowledge of Lebanese physicians about acupuncture, with the intent of conducting larger scale studies and developing strategies aimed at refining this knowledge in the future, and the ultimate goal of setting guidelines for acupuncture practice in Lebanon. Methods: An online survey looking into physicians’ knowledge of acupuncture, its mechanisms of action, effectiveness, indications and safety, and physicians’ understanding of its concepts, was circulated to 4651 physicians registered in the Lebanese orders of physicians. Results: One hundred forty-nine physicians (3.2%) completed the survey. Most study respondents stated that they were unaware of the difference between traditional Chinese acupuncture (TCA) and Western medical acupuncture (WMA). Overall, 30% of respondents had personally used and/or referred patients for acupuncture. Physicians who had personally tried acupuncture were more likely to refer patients for acupuncture (p < 0.001). Those who know the difference between WMA and TCA were more likely to have tried or referred for acupuncture (p = 0.004). 72% believed that acupuncture and other integrative medicine modules should be introduced in medical curricula in Lebanon. Conclusion: Interest in acupuncture among physicians in Lebanon appears to be limited, based on the low response rate. Among respondents, physicians who had tried or referred patients for acupuncture appeared to be more well informed about different acupuncture styles.

ABSTRACTMolecular wires of charge transfer molecules were formed by co-evaporating the 7 7 8 8-Tetracyanoquinodimethane [TCNQ] (acceptor) and Tetrathiafulvalene [TTF] (donor) molecules across prefabricated metal electrodes. Molecular wires of TTF TCNQ were also formed by evaporating single complex of TTF:TCNQ across prefabricated metal electrodes The prefabricated metal electrodes were made using electron beam lithography on SiO2 and glass cover slip substrates. Even though TTF: TCNQ wires grown from both co-evaporation and evaporation techniques show semiconductor like behavior in temperature dependence of resistance they show different activation energies due the difference in stoichiometry of TTF and TCNQ.
