    With increasing number of mobile devices, newly introduced smart devices, and the Internet of things (IoT) sensors, the current microwave frequency spectrum is getting rapidly congested. The obvious solution to this frequency spectrum congestion is to use millimeter wave spectrum ranging from 6 GHz to 300 GHz. With the use of millimeter waves, we can enjoy very high communication speeds and very low latency. But, this technology also introduces some challenges that we hardly faced before. The most important one among these challenges is the Line of Sight (LOS) requirement. In the emergent concept of smart cities, the wireless emergency network is set to use millimeter waves. We have worked on the problem of efficiently finding a line of sight for such wireless emergency network antennae in minimal time. We devised two algorithms, Sequential Line of Sight (SLOS) and Tiled Line of Sight (TLOS), both perform better than traditional algorithms in terms of execution time. The tiled line of sight algorithm reduces the time required for a single line of sight query from 200 ms for traditional algorithms to mere 1.7 ms on average

    Background: Men’s reproductive health directly affects the partner’s reproductive health. Men also may serve as gatekeepers to women’s access to reproductive health services. “Male involvement” in reproductive health and family planning programmes is not just promoting the use of male methods of contraception, but men’s supportive roles in their families. Objectives: 1. To know the attitudes of men regarding the family planning and women’s health. 2. To know the involvement and participation of men in maternity, delivery, post-natal care and family planning. 3. To study the treatment seeking behaviour of men for the reproductive health. problems. Methods: The study was conducted on the auto-rickshaw drivers in the Hoskote town. Total 96 married men were interviewed using a well-designed and pretested questionnaire. The aspects covered are awareness and practices related to RTIs/STIs/HIV/AIDS, family planning, antenatal care and treatment seeking behaviour for the reproductive health problems. Results: Majority (62.50%) of the men did not help their wives seek antenatal care. Only few 7(7.29%) were aware of parameters of antenatal care. There were 44 (45.83%) men who reported the symptoms of reproductive tract infections (RTIs). Among the men suffering from RTIs, only 32(72.73%) took treatment. Only 6(6.25%) people were aware of the all family planning methods. There were 39 (40.63%) participants having extramarital sexual relations with prostitutes or other females, of which 25(64.10%) people do not use condoms while engaging in the high risk sexual encounters. There were 34 (35.42%) men not aware of HIV/AIDS. Conclusion: Antenatal care and family planning are considered the primary responsibility of the women. Also majority of the men in the study group have high risk sexual behaviour. The awareness regarding HIV/AIDS is low

    Background: Gender-based violence is universal, differing only in scope from one society to the other. The most common form of violence against women is domestic violence or violence within families. Objectives: 1. To study the prevalence and different forms of domestic violence perpetrated by intimate partner against married women. 2. To study socio economic and demographic factors which affect the victimization of woman for domestic violence. 3.To study prevalence of sexually transmitted infection and its association with domestic violence in the study group. Methods: Based on a pilot study results, a sample size of 257 was determined. Total 257 currently married women in the reproductive age group (15-49 yrs) were interviewed by systematic random sampling with prior consent using a well designed, pre- tested questionnaire . All the women were screened for sexually transmitted infections as per the WHO guidelines by syndromic approach. The data was analyzed by percentages and chi-square test. Results: Prevalence of domestic violence was found to be 29.57% in the study group. Verbal abuse was reported by 81.58% of the women, Physical abuse by 31.58% of the women ,Psychological abuse by 27.63% of the women and Sexual abuse by 10.53% of the women. Among the 76 victimized women none of them reported to the police. Interpretation and conclusions: The vulnerability to domestic violence was found significantly associated with age at marriage, duration of marriage and addiction of husband to alcohol. The association between domestic violence and sexually transmitted infections was also found significant

    Effect of Neem Oil on Sperm Mitochondrial Activity

    It is a known fact that neem oil has some effect on motility of sperm. Motility of sperm depends on mitochondrial activity present in mid-piece of sperm. In the present study, the mitochondrial activity of sperm was evaluated after treating semen with the different quantities of neem oil. The mitochondrial activity was also evaluated after subjecting the semen samples for different incubation periods keeping the quantity of semen as well as that of neem oil same. Tests were done on thirty normozoospermic semen samples with motile score more than 75%. It was found that as the quantity of neem oil increases, the mitochondrial activity decreases significantly (P < 0.001). Similar results were found, when same quantity of neem oil was treated with same quantity of semen, but incubating for different time durations. The mitochondrial activity decreases significantly (P < 0.001) from one minute to twenty minutes. So, it indicates that as the contact period between neem oil and semen increases the mitochondrial activity decreases significantl

    This paper reports on the design and operation of a flexible power source integrating a lithium ion battery and amorphous silicon solar module, optimized to supply power to a wearable health monitoring device. The battery consists of printed anode and cathode layers based on graphite and lithium cobalt oxide, respectively, on thin flexible current collectors. It displays energy density of 6.98 mWh/cm(2) and demonstrates capacity retention of 90% at 3C discharge rate and ~99% under 100 charge/discharge cycles and 600 cycles of mechanical flexing. A solar module with appropriate voltage and dimensions is used to charge the battery under both full sun and indoor illumination conditions, and the addition of the solar module is shown to extend the battery lifetime between charging cycles while powering a load. Furthermore, we show that by selecting the appropriate load duty cycle, the average load current can be matched to the solar module current and the battery can be maintained at a constant state of charge. Finally, the battery is used to power a pulse oximeter, demonstrating its effectiveness as a power source for wearable medical devices
