Probabilistic Analysis of an Automatic Power Factor Controller with variation in Power Factor
International Journal of Engineering Science and Technology , 2012,
Abstract: In the present study, the probabilistic analysis of an automatic power factor controller (APFC) system working in industry/factory is investigated. The power factor correction of electrical loads and energy losses due to poor power factor are the problems common to all industrial companies. Therefore, the study of APFC unit is of greatimportance. Initially, the system is operative with controlled power factor. Then it may transit to state with power factor not controlled. On the failure of the system, an inspection is carried out to detect the type of failure. The system may fail due to Fuse blown off, Transformer burnt, Programming problem, Output relay faulty. In case of the first two types of failure the components are replaced and corrected; while in last two types of failures the problem is repaired and corrected. The system remains in up state with power factor controlled and power factor not controlled. The system is analyzed by making use of regenerative point technique. The various measures of system effectiveness are obtained including the profit incurred to the system. Graphs have been plotted to depict the behavior of the profit with respect to revenue/loss per unit up time when power factor controlled and when power factor not controlled, cost per unit replacement.
Anaerobic Membrane Bioreactor as Highly Efficient and Reliable Technology for Wastewater Treatment—A Review  [PDF]
Meenu Jain
Advances in Chemical Engineering and Science (ACES) , 2018, DOI: 10.4236/aces.2018.82006
In this review paper, Anaerobic Membrane Bioreactor (AnMBR) is considering as highly efficient and reliable technology for organic material removal from wastewater with no additional energy requirement for aeration. AnMBR is a combination of conventional anaerobic technology and modern membrane system. AnMBR is cost effective alternative technology with pros of anaerobic microbial activity because Methogenic microorganism can convert organic pollutant load of wastewater into renewable energy in the form of methane rich biogas, this conversion is mainly done by transformation of organic matter into energy by high chemical oxygen demand (COD), total suspended solid (TSS) and pathogens removal. Methane rich biogas can be used as a storable source of supplemental energy for the production of heat or power thus AnMBR technology provides improved effluent quality, reliability, and efficiency over the other traditional technologies. This review paper is included the overview of AnMBR, the advantages over other wastewater treatment technology, operational constraints and the concerned factors that has affected the performances of implemented systems, applications of AnMBR for various types of wastewaters, research and development summary and future perspective for further research.
An unusual case of ovarian torsion with infarction simulating malignancy in an adolescent girl  [PDF]
Madhu Jain, Kusum Lata, Shivi Jain
Open Journal of Obstetrics and Gynecology (OJOG) , 2011, DOI: 10.4236/ojog.2011.13022
Abstract: Torsion of the ovary is an uncommon condition. It is the 5th most common gynaecological emergency. It most commonly occur in reproductive age group, on right side, often in presence of congenital abnormalities of adnexa but may occur in their absence too. Adnexal torsion often poses a diagnostic challenge because of non specific symptoms of presentation. Ultrasound with colour Doppler may be helpful.
An association between maternal lead and cadmium levels and birth weight of the babies in North Indian population  [PDF]
Divya Dwivedi, Madhu Jain, Shuchi Jain
Open Journal of Obstetrics and Gynecology (OJOG) , 2013, DOI: 10.4236/ojog.2013.33061

Lead is listed as the 2nd and Cadmium as the 7th hazardous substance by the Agency for Toxic Substances and Disease Registry (ATSDR). Exposure to Lead and Cadmium above the permissible levels among pregnants may cause adverse effects on newborns in the form of Low Birth Weight and Preterm Labor, etc. The objectives of this study were to find out the level of Lead and Cadmium in maternal venous blood and cord blood and to find out the association of the levels of these metals with birth weight of babies. For this, the venous blood and cord blood were collected and quantitative estimation of Lead and Cadmium was carried out by Double Beam Atomic Absorption Spectrophotometer in 1000 women with average Body Mass Index. Results showed higher mean maternal blood Lead level (11.08 μg/dl with range of 2.6 - 21.3) than the normal recommended by Centre of Disease Control and Prevention (10 μg/dl). On the contrary, the mean Cadmium level was 0.095 μg/dl, which was below the normal value as assigned by WHO (0.1 μg/dl). In high Lead exposure group (>10 μg/dl), 43.7% of babies and in high Cadmium exposure group (>0.1 μg/dl), 46.2% of babies were found to have low birth weight. However, this was not statistically significant. Further research in this area in a larger sample size may provide information relevant enough to be transferred to decision makers to implement measures to effectively reduce heavy metals from the environment, thereby protecting future generations from their deleterious effects.

A Rare Fatal Case of Internal Hernia Caused by Meckel’s Diverticulum in a Paediatric Patient  [PDF]
Vandana Jain, Sanjay Sahi
Open Journal of Pediatrics (OJPed) , 2011, DOI: 10.4236/ojped.2011.12005
Abstract: We describe a very rare case of an internal hernia associated with a Meckel’s diverticulum, which lead to the death of a young 3 year old boy. The case describes symptoms of abdominal pain and vomiting, on a background of previous intermittent abdominal pain. The possibility of small bowel obstruction was suspected, and appropriate imaging was performed. This case illustrates the need for a high index of suspicion for small bowel obstruction, with appropriate investigations and review. It also highlights the limitations of imaging modalities in identifying complications of Meckel’s diverticulum. It is important to raise awareness of this fatal cause for small bowel obstruction and to help identify suggestive imaging features, which may point towards a possible complicated Meckel’s diverticulum. Earlier recognition and diagnosis could reduce morbidity and mortality.

Photon Emission from Quark Gluon Plasma at RHIC and LHC  [PDF]
Poonam Jain, Yogesh Kumar
Journal of Modern Physics (JMP) , 2014, DOI: 10.4236/jmp.2014.58080

We work on photon production through annihilation and Compton, and annihilation with scattering (AWS) processes through a quark-gluon plasma (QGP) in high energy nuclear collision incorporating the parametrization factors in strong coupling value and thermal dependent quark mass obtained through a coupling value. We find that photon yield increases with the increasing of the temperature and dominated by early times. We also compare the influence of coupling value on the spectrum of thermal photons. The production rate of photons is observed in the range of low and intermediate transverse momentum. The results are compared with other work.

A Multiobjective Optimization Method for Designing M-Channel NPR Cosine Modulated Filter Bank for Image Compression  [PDF]
Anamika Jain, Aditya Goel
Engineering (ENG) , 2015, DOI: 10.4236/eng.2015.72008
Abstract: This paper proposes a method to design multichannel cosine modulated filter bank for image compression using multiobjective optimization technique. The design problem is a combination of stopband residual energy, least square error of the overall transfer function of the filter bank, coding gain with dc leakage free condition as constraint. The proposed algorithm uses Non-dominated Sorting Genetic Algorithm (NSGA) to minimize the mutually contradictory objective function by minimizing filter tap weights of prototype filter. The algorithm solves this problem by searching solutions that achieve the best compromise between the different objectives criteria. The performance of this algorithm is evaluated in terms of coding gain and peak signal to noise ratio (PSNR). Simulation results on different images are included to illustrate the effectiveness of the proposed algorithm for image compression application.

Mohit Jain, Satish Chand
Wireless Engineering and Technology (WET) , 2016, DOI: 10.4236/wet.2016.71003
Abstract: One of the fundamental properties of an ad hoc network is its connectivity. Maintaining connectivity in wireless networks is extremely difficult due to dynamic changing topology of MANETs. There are several techniques to understand the connectivity level for a given network topology. In this paper, we examine the existing methods and discuss the issues and challenges that are still insurmountable in order to enhance the connectivity properties of wireless multi hop networks.
