Quad-band FSS for Electromagnetic Shielding

In this paper, a novel method to design Quad-band stop frequency selective surface (FSS) is proposed to shield medical/non-medical devices from electromagnetic radiation of wifi/Bluetooth, GPS,1G, 2G, 3G, 4G and 5G frequencies. The proposed device can also be used in security and surveillance devices to protect them from electromagnetic attack. The FSS unit cell consists of convoluted structures on FR4 substrate. The study was performed by designing individual frequency selective surfaces for 1G, 2G, Wi-Fi/Bluetooth, GPS, 4G and 5G, then combining it to form a single Quad-band FSS unit

An Empirical Evaluation Of Predictive Models Of Programmer Navigation

The process of software development consists of many activities, such as writing code, debugging, and navigating through code. Navigating through the code to understand or seek information for developing new code is a very time consuming and tedious task. Many tools are developed based on predictive models to help programmers in navigation. These models predict the fragments of code which might be of developer’s interest. There have been studies for comparing these models to determine their predictive accuracy. However, the models are often based on crude approximations of where a developer’s attention is. For example, prior work has both where the developer’s cursor location as well as what is on the center of the screen to approximate where he/she is looking. To address this concern, we conducted an empirical evaluation of these approximations to see how well they agree with a human evaluator’s perception of where the developer’s attention is. We conducted a replication study on 10 participants and manually coded their navigation pattern. The goals of the study was to evaluate the generalizability of prior work as well as to evaluate the prior operationalizations of navigation. The key findings of this study are: (a) The operationalization based on where the programmer clicks agreed most closely with human evaluator’s assessment and, (b) prior navigation results did not generalize well likely due to small sample size and particulars of the task content

Labour Migration in Indo-Gangetic Plains: Determinants and Impacts on Socio-economic Welfare

In India, male out-migration from rural to urban areas has increased in recent years, especially in the Indo- Gangetic regions of the country. This indicates that most of the developed regions of India are utilizing labour force of backward areas. The paper has investigated on labour out-migration from the states of Uttar Pradesh and Bihar to find its determinants and its impacts on farm economy. The analysis of determinants shown that the number of members in a family and their educational status have a positive impact on migration. As a result of male out-migration, the women left behind in the villages assume a major role in various farm activities resulting in the so-called ‘feminization of agriculture’. It has also empowered the female members of the migrant households in terms of enhancing their decision-making role in various activities. The study has observed some policy implications in terms of formation of self-help groups or labour societies to help out-migrants, organization of training programmes for capacity building of women, more thrust on education a girl-child and development of infrastructure in the rural areas.Labour migration, Feminization of agriculture, Farm-women empowerment, Impact on farm socio-economy, Agricultural and Food Policy, J61, J23, J31,

Integrated nutrient management to enhance biochemical resistance in rice against sheath blight

Application of potassium either as recommended, deficient or excess dose, enhanced the level of phenolic contents, increased incubation period and thereby decreased the sheath blight severity. Application of nitrogen and phosphorous, either as recommended, deficient or excess dose resulted in reduction of phenolic content, shorter incubation period and thereby increasing the sheath blight severity. Recommended sulphur application, enhanced the phenolic contents, increased incubation period and thereby decreased the sheath blight severity. Recommended zinc application resulted in enhancement of phenolic contents, longer incubation period and thereby decreasing the sheath blight severity. Excess application of zinc, reduced the phenolic contents and incubation period but the severity of sheath blight was also lowered down. Recommended iron application (1.5 kg./ha) enhanced the phenolic contents and incubation period with a decreased level of sheath blight severity. Deficient and excess doses of iron also showed the similar trend of effect on phenolics, incubation period and sheath blight severity

Adoption of Integrated Pest Management Practices in Paddy and Cotton: A Case Study in Haryana and Punjab

The study has examined the adoption of IPM practices on cotton in Punjab and on paddy in Haryana and has assessed the impact of key socio-economic and institutional factors on IPM adoption. The Poisson count regression models have been used to analyze technology adoption. The awareness generation about technology through formal crop-specific IPM training provided by the farmers’ field schools has been found extremely effective in wider adoption of IPM in the study areas. Hence, investment in IPM education through these programmes will have long-term beneficial impact. Regarding effectiveness of extension services, the study has not shown (frequency of meeting extension personnel) any statistically significant impact on IPM adoption rates. Mixed evidence has been observed about the relationship between farm-size and adoption of IPM practices. In the case of paddy, a negative relationship has been observed, while the cotton has shown a positive relationship. The study has concluded that a higher gross value of crops does not appear to have a positive impact on IPM technology adoption in cotton.Crop Production/Industries,

Patient profile of gestational trophoblastic disease at Patan Hospital, Nepal

Introductions: This study was designed to determine the demographic pattern, incidence, clinical features and management outcome of gestational trophoblastic disease (GTD) in Patan Hospital. Methods: This is a cross sectional study conducted at Patan Hospital from April 13, 2008 to April 12, 2013. Medical record of cases diagnosed as GTD were retrieved from the record section for review. The age, parity, estimated gestational age at the time of evacuation, presence or absence of vaginal bleeding, uterine size in relation to gestational age, ultrasonogram report and urinary beta human chorionic gonadotropin level, histopathology findings, modalities of treatment and outcomes were analyzed. Results: There was total of 41,543 deliveries during five year study period and 54 GTD on histopathology. Among the 54 GTD, 40 (74%) were molar pregnancy, 8 (14.4%) invasive mole and 6 (11%) choriocarcinoma. The frequency of GTD was 1 per 769 pregnancies. The age of the women with GTD ranged from 15 -50 years. Half of the cases were below 25 years.  Most of the women presented between 8-12 weeks of gestation and below third gravida. Amenorrhea with vaginal bleeding was seen in 49 (90%) patients. Conclusions: The most common GTD observed in this study was molar pregnancy. Vaginal bleeding and lower abdominal pain were the most common complaints at presentation. Keywords: choriocarcinoma, gestational trophoblastic disease, molar pregnancy, persistent trophoblastic diseaseÂ

Management of sheath blight in rice through application of Validamycin, Trichoderma harzianum and Pseudomonas fluorescence

Eleven different combinations of Trichoderma harzianum, Psedumonas fluorescens and Validamycin 3L, were applied at different crop stages viz. seed, seedling, tillering and symptoms initiation along with one application of Carbendazim as standard control to test their efficacy against sheath blight of rice caused by Rhizoctonia solani under field condition. One application of Carbendazim @ 0.1% at the time of symptoms initiation (with 81.36 percent reduction of disease incidence, 83.17 percent reduction in disease severity and 62.92 percent inhancement in yield) and seed treatment with Trichoderma harzianum and seedling root dipping with Pseudomonas fluorescens and two spraying of Validamycin i.e. at tillering and symptoms initiation stages (with 69.10 percent reduction of disease incidence,83.17 percent reduction in disease severity and 62.49 percent inhancement in yield) were found to be equally and highly effective in reducing the sheath blight severity and in increasing rice grain yield also. One spraying of Validamycin at symptoms initiation stage was comparatively less effective (29.54 per cent reduction in disease incidence,53.46 per cent reduction in disease severity and 47.76 per cent enhancement in yield ) than one spraying of Carbendazim at symptoms initiation stage

Endometrial evaluation with methylene blue staining in patients with normal hysteroscopy

Background: Normally, endometrium comprises of non-absorptive epithelium and does not take up stain. Conventional staining with methylene blue is explained on the basis of existence of apoptotic cells in endometrium.Methods: Of 50 patients of unexplained infertility, AUB, recurrent pregnancy loss were randomly selected and included in the study. Those with abnormal ultrasound and history of tuberculosis were excluded. Conventional hysteroscopy was performed using normal saline as distending medium and in those with grossly normal endometrium were subjected to staining with 5% methylene blue instilled trans cervically. After 5 min, irrespective of the size and pattern, focal dark blue stained areas were considered abnormal and randomly biopsied. Incidence of endometritis in both groups was compared after histopathological examination.Results: Of total 50 patients, histopathological report of only one patient with dark blue staining had evidence of endometritis. Rest had no evidence, of which 73.5% had light blue or unstained areas and 26.5% showed dark blue staining. No statistically significant difference was found between histopathological reports and light or dark blue staining (p=0.28). When percentage stained area was considered more than 50% only to be positive, sensitivity was 100%, specificity 94%, PPV 25% and NPV 100%. False positives were 75% and no false negatives were observed. Although p values improved but still statistically insignificant.Conclusions: Present study failed to establish any significant correlation between staining pattern and detection rate of endometritis. With no Indian studies published on chromohysteroscopy so far, role of methylene blue in detection of subtle endometrial changes in modern gynaecology in Indian subpopulation is yet to be established
