    Marine fisheries have very important roles for food supply, food security and income generation in India. About one million people work directly in this sector, producing 3.1 million tonnes annually. The value of the marine fish landings have been estimated at Rs. 36,964 crores in 2010 and India has earned a foreign exchange of Rs. 10,000 crores through the export of 6 lakh tonnes of sea food products. The fisheries sector, presently contributes around one percent to the GDP and 4.72 percent to Agricultural GDP of our country (Sathiadhas et al., 2012). Being open access to a large extent, there is intense competition among the stakeholders with varied interests to share the limited resources in the coastal waters, which has resulted in overfishing and decline in stocks of a few species. Climate change renders severity to this situation and act as a dispensatory factor on fish populations. Further, it will also have strong impact on fisheries with far-reaching consequences for food and livelihood security of a sizeable section of the population

    A simple, rapid, precise, sensitive and reproducible reverse phase high performance liquid chromatography (RP-HPLC) method has been developed for the quantitative analysis of Dolutegravir and Rilpivirine in pharmaceutical dosage form. Chromatographic separation of Dolutegravir and Rilpivirine was achieved on Waters Alliance -2695, by using Luna C18 (250mm x 4.6mm, 5µm) column and the mobile phase containing 0.1% OPA & ACN in the ratio of 50:50 v/v. The flow rate was 1.0 ml/min, detection was carried out by absorption at 245 nm using a photodiode array detector at ambient temperature. The number of theoretical plates and tailing factor for Dolutegravir and Rilpivirine were NLT 2000 and should not more than 2 respectively. The linearity of the method was excellent over the concentration range 10-150 µg/ml and 5-75 µg/ml for Dolutegravir and Rilpivirine respectively. The correlation coefficient was 0.999. % Relative standard deviation of peak areas of all measurements always less than 2.0. The proposed method was validated according to ICH guidelines. The method was found to be simple, economical, suitable, precise, accurate & robust method for quantitative analysis of Dolutegravir and Rilpivirine study of its stability

    A rare presentation of a pyosalpinx in a post-menopausal woman

    Primary fallopian tube carcinoma is a rare tumour of the female genital tract with an incidence of 0.1-1.8% of all genital malignancies, which is generally an intra-operative or a histological diagnosis.  It is a tumour that resembles epithelial ovarian cancer. A 61-year-old postmenopausal woman presented with complaints of continuous bleeding per vaginum with history of loss of appetite and weight for 6 months. She was also a known diabetic and hypertensive. On examination, per abdominal, per speculum and per vaginal findings were unremarkable.  A transvaginal ultrasonography done previously showed fluid in the endometrial cavity suggestive of hematometra/pyometra due to cervical stenosis. A fractional curettage done previously had shown strips of acanthotic squamous epithelium in the endocervical curetting.   She underwent abdominal hysterectomy with bilateral salpingo ovariectomy. Histopathological findings were suggestive of primary fallopian tube adenocarcinoma. Hence the patient was advised chemotherapy followed by a second look laparotomy. Preoperative diagnosis of fallopian tube carcinoma is difficult due to the silent course of this neoplasm and is usually first appreciated at the time of operation or by a pathologist. The treatment approach is similar to that of ovarian carcinoma, and it should consist of a total abdominal hysterectomy with bilateral salpingo-ovariectomy, omentectomy and lymph node dissection from the pelvic and the para-aortic regions

    The concept of employee participation in organization’s decision making is not new. However, the idea couldn’t gain that much popularity among organizations. Studies have shown that only 3-5 percent of organizations have actually implemented this concept in their daily operations. Jute Industry is one of the oldest and high labour intensive industries particularly unskilled and semiskilled. This industry lost huge number of manly hours and productivity due to poor industrial relations. Various studies revealed that the industrial relations are improved in post liberalization in India. So, the researcher studied the importance and application of participative management in post liberalization in this industry. The researcher collected the opinions from the sample respondents through a questionnaire and analyzed with five point Likert scale and weighted average. It reveals in post liberalization employers recognized the importance of participative management which improve the operational efficiency of the employees and maintain cordial industrial relations. Keywords: Participative Management, industrial relations, liberalization, jute industry, operational efficiency, productivity, employee involvement, job enrichment

    Distributed Denial of Service (DDoS) attacks is large-scale cooperative attacks launched from a large number of compromised hosts called Zombies are a major threat to Internet services. As the serious damage caused by DDoS attacks increases, the rapid detection and the proper response mechanisms are urgent. However, existing security methodologies do not provide effective defense against these attacks, or the defense capability of some mechanisms is only limited to specific DDoS attacks. Therefore, keeping this problem in view author presents various significant areas where data mining techniques seem to be a strong candidate for detecting and preventing DDoS attack. The new proposed methodology can perform detecting and preventing DDoS attack using MapReduce concepts in Big Data.Thus the methodology can implement for both detecting and preventing methodologies

    Ardita is considered as one among the Vata Nanatmaja Vyadhis described in our Ayurvedic classics. It can be correlated with the disease Bells Palsy in modern aspects. The present study was conducted with an objective to find out the effective Ayurvedic management in Bells palsy. For present study, a 28 years old Hindu male having history of watering from right eye, difficulty in closing right eye, difficulty in moving up right eyebrow, difficulty in moving up right eyebrow with uneven frequency since last 5 years was registered in our OPD. History and examinations lead to the diagnosis of idiopathic facial nerve paralysis i.e. Bells palsy. Considering the signs and symptoms patient was treated on the lines of Ardita Chikitsa. Nasya Chikitsa with Bala Bilva Ghrita, Tarpana with Jeevantyadi Ghrita, Karnapoorana with Ksheer- Bala Taila were done along with oral drugs and exercise. 100% relief was found in watering from eyes, slurring of speech, dribbling of saliva from right corner of mouth (Lalasrava), earache (Karnshool). 75% relief was found in trapping of food between gums and cheek. 50% relief was found in widening of palpebral aperture (Netra Vikriti), absence of Nasolabial fold and in smiling sign. Before starting the treatment the House Brackmanns grading of facial nerve was Grade 4 and after commencement of 28 days treatment it was Grade 2. There was no side effect observed during and after the treatment
