Fuzzy enhanced Cluster based Energy Efficient Multicast Protocol for Increasing Network Lifetime in WSN
99–102Wireless Sensor Networks (CWSN) consists of sensor node which is mobile roaming inside and outside the network region. The difficulty in existing models observed is to identify the best routes for forwarding packets. If the balancing of packet arrivals and energy conservation is not achieved, it may lead to reduction of network lifetime. In our research work, Fuzzy enhanced Cluster based Energy Efficient Multicast Protocol (FCEEMP) is developed based on three aspects. First one, the establishment of multicast routing based on the calculation of best route metric and average reliability metric. Second, the cluster is formed based on node stability and route capability. Three set of nodes are formed in the cluster network model i.e. sensor node, cluster member and Cluster Head (CH) to estimate energy consumption. Third, enhancement of fuzzy model is implemented to produce optimal energy and the value of network lifetime. From the simulation analysis, proposed protocol achieves better improvement over existing schemes
Design and Development of Network Reliability based Secure Multicast Routing Protocol for MANET
In Mobile Ad hoc network (MANET), link quality and stability of links as well as nodes play a major role. In ad hoc network, links are often changing which could affect the node mobility and integrity of data packets. In this research work, Network Reliability based Secure Multicast Routing Protocol (NRSMRP) is proposed to achieve network reliability by means of creation of reliable multicast tree. This multicast tree is constructed based on link quality and reliability trust metric. In first phase, node categorization and reliability metric calculation are implemented with the help of link quality. In second phase, reliable multicast tree is formed based on parent node and child node. Parent node must have god capacity and signal strength to communicate with child node. In last phase, authentication based multicast routes are established based on the calculation of direct reputation of mobile nodes. From the results, proposed protocol achieves better performance than existing schemes

A Prelimanary Exploration on component based software engineering
Component-based software development (CBD) is a methodology that has been
embraced by the software industry to accelerate development, save costs and
timelines, minimize testing requirements, and boost quality and output.
Compared to the conventional software development approach, this led to the
system's development being completed more quickly. By choosing components,
identifying systems, and evaluating those systems, CBSE contributes
significantly to the software development process. The objective of CBSE is to
codify and standardize all disciplines that support CBD-related operations.
Analysis of the comparison between component-based and scripting technologies
reveals that, in terms of qualitative performance, component-based technologies
scale more effectively. Further study and application of CBSE are directly
related to the CBD approach's success. This paper explores the introductory
concepts and comparative analysis related to component-based software
engineering which have been around for a while, but proper adaption of CBSE are
still lacking issues are also focused
Adrenal Medullary Autografts in Anterior Eye Chamber, Lateral Ventricle and Striatum of Adult Rats: A Long Term Study
The neurobiological basis for the short-term
recovery in Parkinson's patients and experimental
animals grafted with adrenal medulla is
not yet clear. Structural details of the grafted
chromaffin cells are also not available. In the
present study, autografts of adrenal medulla in
the anterior eye chamber, lateral ventricle and
striatum of adult rats were studied for 360 days.
Though a large number of cells degenerated, a
few healthy chromaffin cells survived up to 360
days in the anterior eye chamber. In the ventricular
and striatal regions, cells degenerated
more rapidly, and a few surviving cells were seen
only up to 120 and 150 days, respectively. Degeneration
of the cells was evident from the
alteration of the cytoplasmic granules, appearance
of vacuoles and lysosomes, rapid decline
in the number of TH and DBH positive
cells and diffusion of enzymes in the intercellular
region. Only lymphocytes and connective tissue
cells were seen in the ventricle after 120 days,
while outlines of a few chromaffin cells and
background fluorescence were still evident in the
striatum up to 150 days. In some of the intrastriatal
transplants, morphologically identifiable
Schwann cells were present and, in one
transplant, there was evidence of myelination of
axons by Schwann cells. These axons were obviously
derived from the adjacent host tissue.
From the findings it has been concluded that
autografts of adrenal medulla survive for only a
Limited period of time on transplantation to the
central nervous system and anterior eye
chamber. Survival seemed to be better in the
anterior eye chamber than at the sites
preferentially chosen for treating Parkinson's
patients or experimental animals
Fetal Dopaminergic Neurons Transplanted to the Normal Striatum of Neonatal or Adult Rats and to the Denervated Striatum of Adult Rats
Fetal ventral mesencephalon from the 15th gestational day was grafted into the striatum of neonatal and adult rats. In one group of adult rats, fetal nigra was transplanted into normal striatum. In a second group, the tissue was transplanted at sites where dopaminergic fibers were denervated with 6-hydroxydopamine. The behavior of the dopaminergic neurons and glial reactions were studied by staining with cresyl violet to localize the transplants and by immunolabeling tyrosine hydroxylase (TH) and glial fibrillary acidic protein. In normal adults,
the transplants were small. At the edge of the transplants, TH-positive neurons were packed into clusters, and an interface without any
significant crossover of TH-positive fibers was present. Glial reaction was minimal in and around the transplant. In the denervated
striatum, transplants were generally larger than those in normal striatum and surrounded by a glial scar. TH-positive neurons were both closely
packed and loosely arranged at the periphery of the transplants. Processes could be clearly defined and could be traced to the adjacent host striatum through the TH-free denervated area. In neonates, the transplants were large and at times extended beyond the striatum. Most TH-positive neurons were arranged linearly along the periphery of the transplant. Cell bodies were widely separated and a well-developed neuropil was present. Fibers from the transplant mingled freely with the host striatum without any interface. In all three transplant groups, tracing the TH-positive neurites was easy because they were thicker and coarser than other elements. No apparent glial reaction occurred in the neonates. Thus, the growth and maturation of dopaminergic neurons seemed to vary in different environments. The most conducive environment appears to be neonatal brain in which growth factors are readily available
Study of factors associated with poor glycemic control in Type -2 Diabetic patients
Diabetes mellitus is the most common chronic diseases among adults. By 2030, number will increase to 439 million with prevalence of 7.7 %. Number of deaths in adult due to diabetes is estimated to be 3.96 million per year and mortality rate of diabetes in all ages is 6.8 %, at global level. In India, 40 million have diabetes. By 2025 it is estimated to rise to 70 million. In spite of well-defined treatment for type 2 diabetes, in majority of the people, disease is poorly controlled with existing therapies. Studies like UKPDS and DCCT have proven that poor glycemic control(HbA1C>7%) is associated with increased risk for micro vascular complications. An Indian study showed that the prevalence of diabetes is high in urban India. There is a large pool of subjects with impaired glucose tolerance at a high risk of conversion to diabetes. Hence it would be interesting to identify the factors associated with poor control of diabetes
Development, implementation and evaluation of the online Movement, Interaction and Nutrition for Greater Lifestyles in the Elderly (MINGLE) program: The protocol for a pilot trial
Introduction People with age-related macular degeneration (AMD) are more likely to experience loneliness, have poorer diets and be less physically active than people without AMD. The online Movement, Interaction and Nutrition for Greater Lifestyles in the Elderly (MINGLE) program is a holistic evidence-based intervention aiming to support people with AMD by incorporating physical activity, social interaction and nutrition education components all delivered via a COVID-19-safe Zoom platform. This study will involve two phases: 1) a formative qualitative study with AMD patients to identify the barriers and facilitators to participating in the proposed MINGLE program; and 2) a 10-week pilot study to evaluate the feasibility, acceptability and preliminary efficacy of MINGLE. Methods and analysis Phase 1 involves AMD patients who will be recruited from an eye clinic in Western Sydney, Australia to participate in audio-recorded semi-structured interviews. Verbatim interview transcripts will be coded using the Capability, Opportunity, Motivation and Behaviour (COMB) model and themes established. These themes will be used as a guide to specifically tailor the proposed MINGLE program to people with AMD. Phase 2 involves 52 AMD patients who will then be recruited from the same clinic to participate in the MINGLE program. Prepost questionnaires will be administered to intervention participants to collect information on the following variables: demographics, socioeconomic status, vision function, loneliness, quality of life (including depression), falls risk, physical activity (level), and dietary intake. The acceptability and feasibility of the MINGLE program will also be evaluated using descriptive statistics
