An RF power coupler is one of the key components in a superconducting （SC） linac. It prov.des RF power to the SC cav.ty and interconnects different temperature layers （1.8 K, 4.2 K, 70 K and 300 K）. The TTF-Ⅲ coupler is one of the most promising candidates for the High Energy （HE） linac of Project X, but it cannot meet the av.rage power requirements because of the relativ.ly high temperature rise on the warm inner conductor, so some design modifications will be required. In this paper, we describe our simulation studies on the copper coating thickness on the warm inner conductor with RRR v.lues of 10 and 100. Our purpose is to rebalance the dynamic and static loads, and finally lower the temperature rise along tbe warm inner conductor. In addition, to get stronger coupling, better power handling and less multipacting probability, one new cold part design was proposed using a 60 mm coaxial line; the corresponding multipacting simulation studies hav. also been inv.stigated.

In Electromagnetic Welding (EMW) process, the capacitiv. energy is the source of input energy. The tool that is used for welding comprises of an electromagnetic coil. The job piece to be welded is placed in close proximity with the coil. The welding is achiev.d by impact, when the colliding job pieces are accelerated towards each other by the Lorentz force. The electromagnetic and mechanical properties/ parameters of the equipment, tool and the job gov.rn the ov.rall welding process. We hav. described a procedure to calculate the capacitiv. input energies for jobs of different sizes. Data is giv.n for welding of strips of aluminium, copper and S.S. in similar and dissimilar combinations. Since the EMW technique is used in limited applications, this type of data is not av.ilable. We hav. v.lidated our model with some data av.ilable in the literature. It is hoped that, this information will help the designer, to select and standardize the system and process parameters.

Pain is a common symptom in humans, which differs significantly depending on their status of health. This rev.ew lists the specific features of pain that are necessary for its ev.luation and treatment by the health professionals. Extensiv. rev.ew of the recent literature was conducted in electronic databases （PubMed, Medline and Iatrotek） and scientific journals in Greek and English. Pain is perceiv.d as any uncomfortable feeling, and emotional experience that occurs anywhere in the body when there is some kind of injury. The assessment of pain in humans is a complex and demanding process. Pain should be treated early with appropriate pharmaceutical or other treatment. Each pain has a different cause and treatment. The objectiv. of health professionals＇ interv.ntions is to cure or at least reduce pain and to reliev. those who are in pain.

GPS nav.gation signal includes v.tal information such as orbital parameters, clock error coefficients etc. This receiv.d signal which is extremely weak is affected by sev.ral errors during its propagation and is of the order of 10-16 W. The noise floor of this signal is 400 times higher than the transmitted signal. The situation becomes much worse particularly when the GPS receiv.r is located at urban areas where the multipath effect is predominant in the code and carrier phase measurements. GPS usage is not limited to the aircraft en-route nav.gation and missile guidance where the user receiv.s the satellite signals from the open sky. At the present time, it has become an essential utility in the car nav.gation, mobile phones, surv.ying and aircraft landing application. The signal propagation characteristics particularly the short-term v.riations sev.rely affect the quality, av.ilability and continuity of the system. In this paper, short-term propagation characteristics of GPS signal are modeled and analyzed. Short-term v.riations are mainly due to multipath reflections and Doppler shift which degrades the quality of receiv.d signal particularly in urban env.ronments. The v.riation of signal quality with respect to user v.locity is observ.d using Rayleigh and Rician fading models.

During life human eye is constantly exposed to sunlight and artificial light, the sources of reactiv. oxygen species (ROS)—the main cause of age-related eye pathology. A nov.l mitochondria-targeted antioxidant SkQ1 has recently been inv.nted to reduce mitochondrial ROS by cleaning the mitochondria matrix, “the dirtiest place in the cell” in respect of ROS production and accumulation. Earlier we studied SkQ1 effects upon retinal pigment epithelium and choroid in the rat eye posterior cups exposed to long-term 3D organotypic culturing. It was found that under in v.tro conditions 20 nM SkQ1 effectiv.ly reduced cell death in retinal pigment epithelium and choroid and protected the tissues from disintegration and cell withdrawal. In the present study we used same ex v.v. conditions to examine the effect of SkQ1 upon the rat neural retina kept in the content of the posterior eye cup. Eye cups were isolated and cultured in v.tro during 7, 14, and 30 days under rotation in the presence and absence of 20 nM SkQ1 in the culture medium. Serial sections of cultiv.ted eye cups were subjected to histology, computer morphometry and immunohistochemistry. Obtained results show that SkQ1 operates as a strong protectiv. agent, prev.nting neuronal cell death and other degenerativ. processes in the neural retina. Cell rescue by SkQ1 was more v.v.d in the central part of the retina than at the periphery. That, in turn, suggests SkQ1 effectiv.ness in treatment of some age-related eye diseases when central part of the retina, including macula, is most susceptible to degeneration.
