Background: The need for a rapid, noninvasive method for unwanted hair removal has led to the development of various light SOURCEs for this purpose. Objective: To evaluate the efficacy of Intense Pulsed Light SOURCE (IPLS) on unwanted hairs. Patients & Methods: In this open, uncontrolled clinical trial, 77 different anatomical areas in 34 referred patients to "Novin Didegan Clinic" in Tehran in 1380-1381, were treated by IPLS at fluencies ranging from 22 to 34 j/cm2 after their demographic data and the number of hairs were recorded. The 3 to 7 treatment sessions were accomplished 4 to 6 weeks apart. All of the patients were followed 6 months after the last therapy. The quantitative data were  analyzed by paired t test. Results: Six months after the last therapy, more than 50% reduction in number of hairs was noted in 80% of the treated areas; with mean reduction of 72±23 percent. Side effects were mild and reversible and occurred in ten patients. Conclusion: The IPLS appears to provide an effective and safe method for long term excess hair removal in various skin types.      

Different types of contact, including contact between node pairs, any-contact of nodes, and contacts of the entire network, are used to characterize social relations in mobile social networks. Different modes of ROUTING, from the point of view of message delivery semantics, encompass unicasting, multicasting, any-casting, and broadcasting. Studies have shown that using probability distribution functions of contact data, which is mainly assumed to be homogeneous for nodes, improves the performance of these networks. However, there exists an important challenge in studies on distributions. A lot of works apply the distribution of one type of contact to other types. Hence in ROUTING applications, it causes to use of the distribution of one type of contact for any mode of ROUTING. This study provides a complete solution to model each type of homogeneous contact data distribution and to use them in different modes of ROUTING. We propose a ROUTING algorithm that uses this new model. Results show that our solution improves the average latency of comparing methods Epidemic, TCCB, and DR about 3.5-times, 30%, and 45%, respectively. It achieves a delivery rate of about 5% and 6%, and average latency about 6% and 8% better than that of DR and TCCB, respectively.

Background: The aim of this study is to explore the safety and diagnostic performance of dual-SOURCE CT scan in comparison with single SOURCE CT scan and conventional angiography in patients with coronary heart diseases.Materials and methods: A systematic review was performed using CRD standard methods. The Cochrane Library, MEDLINE, EMBASE, Google Scholar and TRIP were searched up to April 2009. The references of the marked studies and gray literature were also searched.Results: 17 articles were included. 9 articles reported the safety and 12 articles reported the diagnostic performance of DSCT.  Generally DSCT was a non-invasive and safe procedure.  Using DSCT the exposure of patient to X-ray was less than 64-slice single SOURCE CT (SSCT) and more than conventional angiography. For the DSCT the mean sensitivity was 90.4%, mean specificity was 82%, mean PPV was 83% and mean NPV was 96%. For the SSCT the mean sensitivity was 90.4%, mean specificity was 82%, mean PPV was 83% and mean NPV was 96%. The mean sensitivity, specificity, PPV and NPV of DSCT were slightly higher than SSCT.Conclusion: DSCT is a noninvasive and relatively safe technology. The diagnostic performance of DSCT is higher than SSCT, but its performance is not so much high to be able to substitute the conventional invasive angiography which is still the gold standard test.

In Local Area Networks (LAN) connected together by bridges, flow control and smooth traffic in the network is very important. However, congestion at bridges can cause intensive loss of received frames. In addition, the received frames are thrown away and have to be retransmitted by the SOURCE station, which causes more congestion and massive reduction in the overall network throughput. The network has a series topology in which all the LANs use Token Ring protocol at the presence of voice and data services. In the simulation voice traffic has the priority to access the network over the data traffic. In this paper techniques are introduced to reduce congestion at the bridges and improve the overall performance in the LANs connected through bridges. In the first technique data transmission is allowed during voice transmission by bridges. In the second technique the bridges have higher priority of access. The results show that using these techniques significantly improves network throughput.
