Effect of immunostimulant on enhancement of the immune response of kuruma shrimp Marsupenaeus japonicus and its resistance against White Spot Syndrome Virus (WSSV)

An experiment of 45 days duration to test the efficacy of the Vibrio alginolyticus as an immunostimulant was conducted in Marsupenaeus japonicus against white spot syndrome virus (WSSV) infection, considered as one of the serious pathogens of shrimps. The shrimps were fed with the experimental diets coated with different concentrations of bacteria of 17 ml / kg feed and 10 % of animal body wt. They were challenged with WSSV to assess the increase in survival rate and growth if any due to immune enhancement. Another group of shrimp was used for drawing the haemolymph to estimate the increase in the level of prophenoloxidase activity. Samplings for the above said analysis were carried out at 15 days interval for a period of 45 days. The highest prophenoloxidase activity (39.78 with sand substrate-T1) and the highest survival rate (66.66 % with sand substrate-T1) and highest growth rate (7.04 % in 17ml/kg- with sand substrate-T1) were recorded in experimental diet (17 ml / kg feed). Hence the 17 ml / kg feed of Vibrio alginolyticus formalin killed added to the diet could be an eco-friendly and economically viable immunostimulant for penaeid shrimps

Security challenges of small cell as a service in virtualized mobile edge computing environments

Research on next-generation 5G wireless networks is currently attracting a lot of attention in both academia and industry. While 5G development and standardization activities are still at their early stage, it is widely acknowledged that 5G systems are going to extensively rely on dense small cell deployments, which would exploit infrastructure and network functions virtualization (NFV), and push the network intelligence towards network edges by embracing the concept of mobile edge computing (MEC). As security will be a fundamental enabling factor of small cell as a service (SCaaS) in 5G networks, we present the most prominent threats and vulnerabilities against a broad range of targets. As far as the related work is concerned, to the best of our knowledge, this paper is the first to investigate security challenges at the intersection of SCaaS, NFV, and MEC. It is also the first paper that proposes a set of criteria to facilitate a clear and effective taxonomy of security challenges of main elements of 5G networks. Our analysis can serve as a staring point towards the development of appropriate 5G security solutions. These will have crucial effect on legal and regulatory frameworks as well as on decisions of businesses, governments, and end-users

Automated object detection of mechanical fasteners using faster region based convolutional neural networks

Mechanical fasteners are widely used in manufacturing of hardware and mechanical components such as automobiles, turbine & power generation and industries. Object detection method play a vital role to make a smart system for the society. Internet of things (IoT) leads to automation based on sensors and actuators not enough to build the systems due to limitations of sensors. Computer vision is the one which makes IoT too much smarter using deep learning techniques. Object detection is used to detect, recognize and localize the object in an image or a real time video. In industry revolution, robot arm is used to fit the fasteners to the automobile components. This system will helps the robot to detect the object of fasteners such as screw and nails accordingly to fit to the vehicle moved in the assembly line. Faster R-CNN deep learning algorithm is used to train the custom dataset and object detection is used to detect the fasteners. Region based convolutional neural networks (Faster R-CNN) uses a region proposed network (RPN) network to train the model efficiently and also with the help of Region of Interest able to localize the screw and nails objects with a mean average precision of 0.72 percent leads to accuracy of 95 percent object detectio

Study of Stromal Expression of CD 10 in Breast Carcinoma and Its Role as a Prognostic Marker

BACKGROUND : Breast carcinoma is the most common cancer among women, also tops the list of cancer death among women, living in under developed countries. The mortality of breast carcinoma is attributed to metastatic disease.CD10 is a 90-110 kD cell surface metalloproteinase, that may play a role in degrading extra cellular matrix and collagen, providing a microenvironment favourable for invasion and metastasis. AIM AND OBJECTIVES : 1. To study the stromal expression of CD 10 antigen in patients diagnosed as invasive ductal breast carcinoma by histopathological examination. 2. To study relationship with: 1. Age, 2. Menopausal status 3. Histologic subtypes 4.Nottingham’s grade and 3. Nottingham’s Prognostic index, 4. Mitotic rate and 5.Lymph node metastasis of the patients. MATERIALS AND METHODS : A total of 60 patients of breast cancer were included in the study. Representative sections were taken and Hematoxylin and Eosin staining was done. Immunohistochemistry was performed with CD10. Stromal expression of CD10 (10%-30% stromal positivity was considered weak positive, >30% as strong positive) in invasive breast carcinoma was noted and was statistically analysed. RESULTS : Stromal expression of CD10 was found to be significantly associated with increasing tumor grade (P = 0.047), Lymph node metastasis (P = 0.013) and Nottingham’s Prognostic index (P = 0.009). No correlation was found between CD10 expression and age, menopausal status, histologic subtypes, tumour size and mitotic rate. CONCLUSION : The stromal expression of CD10 has significant correlation with higher histological grade , lymph node metastasis, Nottingham’s prognostic index. There is no correlation between CD10 expression and age menopausal status, histologic subtypes, tumour size and mitotic rate. This study highlights the role of stromal CD10 expression in predicting tumor response and prognosis. Hence CD10 could be used as a prognostic marker

A Study on Quality of Life (QOL) in Patients with Schizophrenia

BACKGROUND: Few studies have explored the Quality of Life among patients with schizophrenia In the treatment of schizophrenia the subjective quality of life is an important outcome. AIM OF THE STUDY: To determine the quality of life in patients with schizophrenia in Indian population, and to compare it with individuals without mental illness in general population. This study aimed to identify factors which influenced the quality of life in patients with schizophrenia. METHODOLOGY: This was a Cross sectional study in the Institute of Mental health- a Teaching institute and tertiary care referral centre involving WHOQOL-BREF questionnaire to evaluate the quality of life. Further Positive and negative syndrome scale, Calgary depressive scale for schizophrenia, Beck’s cognitive insight scale, WHODAS-II scale, UKU side effects scale, Social support questionnaire were all employed to study the psychopathology, insight, side effects and social support in the patient group. Descriptive statistics and tests of correlation, multivariate analysis using SPSS software-20 were performed. RESULTS: The quality of life in patients with schizophrenia was found to be lower than the individuals without mental illness. The variables which showed a strong association with quality of life in these patients were gender, age, employment, socio economic background, education, duration and phase of illness. Depression and negative symptoms had a strong correlation with quality of life. Disability and insight also influenced the quality of life. CONCLUSION: It was concluded that it is imperative to study the quality of life in patients with schizophrenia. Depressive and negative symptoms has to be catered to decrease lowering of quality of life. Early treatment and reduction of symptoms also is important an increased duration and active phase of illness causes a decline in quality of life. Disability prevention by early recovery and rehabilitation measures is very important to increase the treatment outcome and thereby the quality of life. The knowledge of these factors in these patients should be crucial to implement health policies and psychosocial rehabilitation programs focused on improving the quality of life of these patients

Analysis of Higher Order Multipoles of the 952.6 Mhz RF-Dipole Crabbing Cavity for the Jefferson Lab Electron Ion Collider

The crabbing system is a key feature in the Jefferson Lab Electron-Ion Collider (JLEIC) required to increase the luminosity of the colliding bunches. A local crabbing system will be installed with superconducting rf-dipole crabbing cavities operating at 952.6 MHz. The field non-uniformity across the beam aperture in the crabbing cavities produces higher order multipole components, similar to that which are present in magnets. Knowledge of higher order mode multipole field effects is important for accurate beam dynamics study for the crabbing system. In this paper, we quantify the multipole components and analyse their effects on the beam dynamics
