Naeem Raza, Muhammad Qasim Akbar, Aized Amin Soofi, Samia Akbar
Journal of Computer and Communications (JCC) , 2019, DOI: 10.4236/jcc.2019.73003
Abstract: Smart Grid (SG) is an emerging paradigm of the modern world to upgrade and enhance the existing conventional electrical power infrastructure from generation to distribution to the consumers in a two-way communication fashion to automate the electrical power demand and supply and make this a cyber-physical system. SG infrastructure key elements, such as smart meters, circuit breakers, transformers, feeders, substations, control centers, grid stations, are required well-formed communication network architectures. SG infrastructure is divided into three main communication networks architectures, such as HAH, NAN, and WAN. Each of these communication network architectures requires reliable, stable, secure, high data rate at real-time with the help of different wireline and wireless communication technologies from HAN to WAN networks. To understand the complete concepts about SG, a concise review is presented and it will help the readers to get foundations of communication network architectures and technologies of SG.

Bhutta,Zulfiqar A; Memon,Zahid A; Soofi,Sajid; Salat,Muhammad Suhail; Cousens,Simon; Martines,Jose;
Bulletin of the World Health Organization , 2008, DOI: 10.1590/S0042-96862008000600013
Abstract: objective: this pilot study investigated the feasibility of delivering a package of community-based interventions for improving perinatal care using lady health workers (lhws) and traditional birth attendants (dais) in rural pakistan. methods: the intervention was implemented in four of eight village clusters (315 villages, total population 138 600), while four served as a comparison group. the lhws in intervention clusters received additional training focused on essential maternal and newborn care, conducted community education group sessions, and were encouraged to link up with local dais. the intervention was delivered within the regular government lhw programme and was supported by the creation of voluntary community health committees. findings: in intervention villages, there were significant reductions from baseline in stillbirth (from 65.9 to 43.1 per 1000 births, p < 0.001) and neonatal mortality rates (from 57.3 to 41.3 per 1000 live births, p < 0.001). the proportion of deliveries conducted by skilled attendants at public sector facilities also increased, from 18% at baseline to 30%, while the proportion of home births decreased from 79% to 65%. a household survey indicated a higher frequency of key behaviours (e.g. early and exclusive breastfeeding, delayed bathing and cord care) in intervention villages. conclusion: the improved stillbirth and neonatal mortality rates observed indicate that community health workers (i.e. lhws and dais) can be effective in implementing a community and outreach package that leads to improved home care practices by families, increased care-seeking behaviour and greater utilization of skilled care providers. these preliminary observations require confirmation in an adequately powered trial.

BMC Research Notes , 2012, DOI: 10.1186/1756-0500-5-6
Abstract: A total of 304,836 students were enrolled in 1,096 public, private, and religious schools (Madrasahs) of the two towns. Five percent of schools refused to participate in the school census. Twenty-five percent of schools had a total enrolment of less than 100 students whereas 3% had more than 1,000 students. Health education programs were available in less than 8% of public schools, 17% of private schools, and 14% of Madrasahs. One-quarter of public schools, 41% of private schools, and 43% of Madrasahs had previously participated in a school-based vaccination campaign. The most common vaccination campaign in which schools participated was Polio eradication program. Cost of the vaccine, side effects, and parents' lack of information were highlighted as important limiting factors by school administration for school-based immunization programs. Permission from parents, appropriateness of vaccine-related information, and involvement of teachers were considered as important factors to improve participation.Health education programs are not part of the regular school curriculum in developing countries including Pakistan. Many schools in the targeted townships participated in immunization activities but they were not carried out regularly. In the wake of low immunization coverage in Pakistan, schools can be used as a potential venue not only for non-EPI vaccines, but for a catch up vaccination of routine vaccines.Vaccination is considered to be the most cost-effective public health tool in preventing infectious diseases responsible for child mortality in developed and developing countries [1]. Immunization programs have led to global eradication of smallpox, elimination of measles and poliomyelitis from certain regions of the world, and substantial reductions in morbidity and mortality attributed to diphtheria, tetanus, pertussis, pneumonia and infectious diarrhea [2]. Such successes have resulted due to the use of safe and effective vaccines against these diseases, in addi

Abstract:

Appendicular Neuroendocrine Tumors (ANETs) in pediatric age group are infrequent. Though children may present like symptoms of acute appendicitis, these tumors are incidentally picked up during routine histological examination of resected appendix. We report our experience with ANETs in children from a tertiary care hospital in Arabian Peninsula. During 6-year period, there were 700 appendectomies performed in children (≤14 years) and we collected only 3 cases of ANETs diagnosed from histological examination of resected appendix. Appendectomy alone has been sufficient in all cases and they are disease free at follow-up till 3 years after surgery. We have reviewed the clinical presentation, diagnosis and management of these cases. With no typical clinical picture, ANET is usually an incidental finding hence we propose that the review of the histology of resected appendix is mandatory to identify the prevalence of ANETs in pediatric population. For most patients, appendectomy is the appropriate treatment and the outcome is excellent after appendectomy.

International Journal of Clinical Medicine (IJCM) , 2014, DOI: 10.4236/ijcm.2014.521181
Abstract:
Background: During the past two decades there has been a sustained decline in child mortality; however, neonatal mortality has remained stagnant. Each year approximately 4 million babies are born asphyxiated resulting in 2 million neonatal deaths and intrapartum stillbirths. Almost all neonatal deaths occur in developing countries, where the majority is delivered at homes with negligible antenatal care and poor perinatal services. Objectives: To identify socio-demographic and clinical risk factors associated with birth asphyxia in Matiari District of Sindh Province, Pakistan. Method: A matched case control study was conducted in Matiari District with 246 cases and 492 controls. Newborn deaths with birth asphyxia diagnosed through verbal autopsy accreditation during 2005 and 2006 were taken as cases. Controls were the live births during the same period, matched on area of residence, gender and age. Result: The factors found to be associated with birth asphyxia mortality in Matiari District of Sindh Province, Pakistan are maternal education, history of stillbirths, pregnancy complications (including smelly or excessive vaginal discharge and anemia), intrapartum complications (including fever, prolong or difficult labour, breech delivery, cord around child’s neck, premature delivery, large baby size) and failure to establish spontaneous respiration after birth. Conclusion and Recommendation: There is an immediate need to develop strategies for early identification and management of factors associated with birth asphyxia by involving women, families, communities, community health workers, health professionals and policy makers. Community health workers should be trained for emergency obstetric care, basic newborn care including preliminary resuscitation measures to provide skilled birth attendance and encourage early recognition and referral.
On the Sample Information About Parameter and Prediction

Statistics , 2011, DOI: 10.1214/10-STS329
Abstract: The Bayesian measure of sample information about the parameter, known as Lindley's measure, is widely used in various problems such as developing prior distributions, models for the likelihood functions and optimal designs. The predictive information is defined similarly and used for model selection and optimal designs, though to a lesser extent. The parameter and predictive information measures are proper utility functions and have been also used in combination. Yet the relationship between the two measures and the effects of conditional dependence between the observable quantities on the Bayesian information measures remain unexplored. We address both issues. The relationship between the two information measures is explored through the information provided by the sample about the parameter and prediction jointly. The role of dependence is explored along with the interplay between the information measures, prior and sampling design. For the conditionally independent sequence of observable quantities, decompositions of the joint information characterize Lindley's measure as the sample information about the parameter and prediction jointly and the predictive information as part of it. For the conditionally dependent case, the joint information about parameter and prediction exceeds Lindley's measure by an amount due to the dependence. More specific results are shown for the normal linear models and a broad subfamily of the exponential family. Conditionally independent samples provide relatively little information for prediction, and the gap between the parameter and predictive information measures grows rapidly with the sample size.
Lessons and implications from a mass immunization campaign in squatter settlements of Karachi, Pakistan: an experience from a cluster-randomized double-blinded vaccine trial [NCT00125047]

Trials , 2006, DOI: 10.1186/1745-6215-7-17
Abstract: A cluster-randomized double blind preventive trial was launched in August 2003 in 60 geographic clusters covering 21,059 children ages 2 to 16 years. After consent was obtained from parents or guardians, eligible children were immunized parenterally at vaccination posts in each cluster with Vi polysaccharide or hepatitis A vaccine. Safety, logistics, and standards were monitored and documented.The vaccine coverage of the population was 74% and was higher in those under age 10 years. No life-threatening serious adverse events were reported. Adverse events occurred in less than 1% of all vaccine recipients and the main reactions reported were fever and local pain. The proportion of adverse events in Vi polysaccharide and hepatitis A recipients will not be known until the end of the trial when the code is broken. Throughout the vaccination campaign safe injection practices were maintained and the cold chain was not interrupted. Mass vaccination in slums had good acceptance. Because populations in such areas are highly mobile, settlement conditions could affect coverage. Systemic reactions were uncommon and local reactions were mild and transient. Close community involvement was pivotal for information dissemination and immunization coverage.This vaccine strategy described together with other information that will soon be available in the area (cost/effectiveness, vaccine delivery costs, etc) will make typhoid fever control become a reality in the near future.Despite major breakthroughs in the development of new vaccines over the past two decades, the gap in access to vaccines between wealthy and poorer countries has widened. As a result, immunization schedules offer more vaccines in high-income countries than in those with low income [1]. Children in low-income countries are also at a disadvantage because vaccine research and development agendas are tailored to the needs of developed countries. The focus the International Vaccine Institute typhoid fever program is to e

Journal of Geological Research , 2012, DOI: 10.1155/2012/839050
Abstract: Bakhtiari dam is located on the Bakhtiari river, 120?km away from the north of the Andimeshk city. Upper diversion tunnel of this dam with large cross section (13.7?m excavation diameter) and more than 1?km length is a huge construction. The tunnel is placed in the Sarvak formation carbonate rocks of Bangestan group which passes through seven different geological zones with various specifications (SV1, SV2, SV3, SV4, SV5, SV6, and SV7). Joint studies show two main discontinuit including bedding and a main group of joint (J1) together with random joints (faults and fractures). Most of discontinuities have been filled mainly by calcite or calcite and clay. Data deduced from testing and analysis shows good-to-excellent RQD classes with 75 to 90 values. Based on RMR and Q methods, generally rock masses have good to very good quality with 61 to 95 values for RMR and 10 to 35 values for Q. Based on conducted stability analysis, suitable supports were suggested for tunnel by RMR and Q methods. As a result, it can be concluded that all units have a good stability. Therefore, systematic rock bolting with 40–50?mm unreinforced shotcrete has been proposed for some special place. For rock support, according to RMR method, 3?m rock bolts in crown, 2.5?m spacing and with 50?mm shotcrete in crown has been proposed also 3?m rock bolts, based on Q method, 2.3-2.4?m spacing with systematic Bolting without shotcrete or 40?mm unreinforced shotcrete in some units, has been proposed. According to RMR method, for SV5 zone with very good and excellent quality, local 33 bolting without shotcrete and 3m rock bolts, 3?m spacing and spot bolting according to Q method has been proposed. 1. Introduction In recent years, following the increasing need to create spaces underground with larger scale and in greater depth in poor areas (such as underwater), identifying more and more of the earth is evident. In relation to construction of dams, geological survey is the most important parts of studies which can be useful and valuable information about the design of underground spaces offer [2]. Feasibility of these constructions in natural materials, such as rock and soil, causes the geological conditions to play a major role in their stability [3]. Dams are considered as one of the most important civil structures. Arch dams with high stresses on their foundation highlight the role of rock mechanics studies. It should be noted that many geological data cannot be directly applied in the design of underground constructions, so in recent years; many efforts have been made for geotechnical
Plasma Internal Energy for Toroidal Elliptic Plasmas with Triangularity  [PDF]
Muhammad Asif
Journal of Modern Physics (JMP) , 2011, DOI: 10.4236/jmp.2011.21002
Abstract: The Plasma internal energy is not conserved on a magnetic surface if nonlinear flows are considered. The analysis here presented leads to a complicated equation for the plasma internal energy considering nonlinear flows in the collisional regime, including viscosity and in the low-vorticity approximation. Tokamak equilibrium has been analyzed with the magnetohydrodynamics nonlinear momentum equation in the low vorticity case. A generalized Grad–Shafranov-type equation has been also derived for this case.
