Performance Analysis of Unbalance Radial Feeder with Time Varying Composite Load  [PDF]
Jagdish Prasad Sharma, H. Ravishankar Kamath
Journal of Power and Energy Engineering (JPEE) , 2015, DOI: 10.4236/jpee.2015.35005
Abstract: The focus of this paper is to present performance indices for unbalance radial feeder having different characteristic and composition of time varying static ZIP load models. These provide a framework for benchmarking of distribution automation projects. 15 minutes characteristics time interval for load flow and load modeling are considered to meet smart grid implementation criterion. A forward-backward sweep method is employed for load flow solution. Developed performance indices were illustrated on modified IEEE 37 node test feeder. Performance indices are useful for analysis, operational, planning and integration of stochastic renewable sources.
Basophil leucocyte response in leprosy with lepromin-A
Okhandiar R,Sharma H
Indian Journal of Dermatology, Venereology and Leprology , 1993,
Abstract: Study of ′Basophil Leucocyte Response′ in two polar groups of leprosy patients (tuberculoid and lepromatous) was undertaken employing Lepromin-A (Armadillo) by the method of Open Window Technique of Rebuck. Significant infiltration of Basophils at the test side is demonstrated both at 48 hours and at 72 hours in lepromatous leprosy as compared to the control groups i.e., in placebo and tuberculin positive healthy volunteers as well as against tuberculoid leprosy group (p value being less than 0.05 and 0.001). The basophils also go into degeneration and degranulation at 72 hours. . The role of basophils in the different types of allergic reactions is discussed in context of above finding. The possible effect of high infiltration of basophils in lepromatous leprosy with its subsequent release of histamine and other factors by degranulation, and its possible role in immuno-regulation through specialised suppressor cells is postulated in the light of available data.
Protein aggregate myopathies
Sharma M,Goebel H
Neurology India , 2005,
Abstract: Protein aggregate myopathies (PAM) are an emerging group of muscle diseases characterized by structural abnormalities. Protein aggregate myopathies are marked by the aggregation of intrinsic proteins within muscle fibers and fall into four major groups or conditions: (1) desmin-related myopathies (DRM) that include desminopathies, a-B crystallinopathies, selenoproteinopathies caused by mutations in the, a-B crystallin and selenoprotein N1 genes, (2) hereditary inclusion body myopathies, several of which have been linked to different chromosomal gene loci, but with as yet unidentified protein product, (3) actinopathies marked by mutations in the sarcomeric ACTA1 gene, and (4) myosinopathy marked by a mutation in the MYH-7 gene. While PAM forms 1 and 2 are probably based on impaired extralysosomal protein degradation, resulting in the accumulation of numerous and diverse proteins (in familial types in addition to respective mutant proteins), PAM forms 3 and 4 may represent anabolic or developmental defects because of preservation of sarcomeres outside of the actin and myosin aggregates and dearth or absence of other proteins in these actin or myosin aggregates, respectively. The pathogenetic principles governing protein aggregation within muscle fibers and subsequent structural sarcomeres are still largely unknown in both the putative catabolic and anabolic forms of PAM. Presence of inclusions and their protein composition in other congenital myopathies such as reducing bodies, cylindrical spirals, tubular aggregates and others await clarification. The hitherto described PAMs were first identified by immunohistochemistry of proteins and subsequently by molecular analysis of their genes.

Chaitanya H. Raut, Atul Kumar, Fanindra Singh Solanki, Deepti B. Sharma, Dhananjay Sharma, Shabbir Hussain
Surgical Science (SS) , 2012, DOI: 10.4236/ss.2012.32016
Abstract: Squamous cell carcinoma of scrotum is not common. It was the first cancer directly associated with a specific occupation i.e. chimney sweeps. We report a case of squamous cell carcinoma of scrotum developed in a patient of stricture urethra with multiple perineal urinary fistulas treated with lay open urethra with buccal mucosal graft. Tobacco exposed buccal mucosa graft can act as a carcinogen for scrotal cancer in patients with multiple fistula and poor hygiene.
Tillage and Rice-Wheat Cropping Sequence Influences on Some Soil Physical Properties and Wheat Yield under Water Deficit Conditions  [PDF]

Open Journal of Soil Science (OJSS) , 2012, DOI: 10.4236/ojss.2012.22011
Abstract: Adopting a better tillage system not only improves the soil health and crop productivity but also improves the environment. A field experiment was conducted to investigate the effects of tillage and irrigation management on wheat (Triticum aestivum L.) production in a post-rice (Oryza sativa L.) management system on silty clay loam soil (acidic Alfisol) for 2003-2006. Four irrigation levels (RF: rainfed; I1: irrigation at crown root initiation (CRI); I2: irrigation at CRI + flowering; I3: irrigation at CRI + tillering + flowering), and two tillage systems (ZT: zero tillage and CT: conventional tillage) were tested. Zero tillage compared to CT, resulted in higher bulk density (1.34 vs 1.23 Mg –3), lower total porosity (48.7 vs 52.9%), higher penetration resistance (1.51 vs 1.37 MPa), lower saturated hydraulic conductivity (1.60 vs 92.0 mm h–1), lower infiltration rate (9.40 vs 36.6 mm h–1) and higher volumetric available water capacity (7.9 vs 7.5%) in the surface 0.15 m soil layer. Irrigation levels significantly affected crop water use, wheat yield, and water use efficiency (WUE). Average total water use was 461, 491, 534 and 580 mm under RF, I1, I2 and I3 treatments, respectively. Grain and straw yield of wheat were statistically the same under ZT and CT during 2003-2004; the values, averaged over four irrigation levels were 2.10 and 2.38 Mg a–1 for grain, and 3.46 and 3.67 Mg a–1 for straw, respectively. Grain yield declined by 22%, 11% and 8% of I3 (2.32 Mg ha–1) with RF, I1 and I2 treatments, respectively, under ZT; and by 13%, 8% and 5% of I3 (2.61 Mg ha–1) with RF, I1 and I2 treatments under CT. Average values of WUE were 4.33 kg ha–1 m–1 and 2.35 m3–1 grain for the ZT and CT treatments. Wheat yield increased with increased irrigation levels for all the cropping seasons. Results from this study concluded that ZT system was better compared to the CT system even with lower yields due to lower input costs for this treatment.
Harnessing REDD+ opportunities for forest conservation and carbon stock enhancement in the Northeastern States of India  [PDF]

Natural Science (NS) , 2013, DOI: 10.4236/ns.2013.53048
Abstract:



Forests have significant economic and ecological value as a provider of ecosystem services, being home to much of the world’s biodiversity and supporting the livelihoods of many people. Reducing emissions from deforestation and forest degradation in developing countries (REDD) is a critical component of the overall greenhouse gas emission reductions and now the significance of REDD+ (which is not only about reducing emissions but halting and reversing forest loss), in delivering climate change mitigation benefits along with co-benefits, is increasingly being recognized in global climate negotiations. Northeast India provides a tremendous potential for harnessing REDD+ activities with about 66% of the total geographical area of the region being covered by forests. This paper attempts to explore this potential besides estimating the area available for different options under REDD+ as well as the mitigation potential using COMAP model, overcoming limitations of existing studies or a lack of them. Within this, the status of forests and biodiversity along with drivers of deforestation in north east India are documented and an assessment of the potential for taking up reducing deforestation and degradation and enhancement of carbon stocks and afforestation is conducted both at the state as well as district level. It was found that northeastern states have been experiencing net forest loss during the last few years along with significant scale forest degradation, with Nagaland followed by Arunachal Pradesh offering maximum potential for “reducing deforestation” option under REDD and the total incremental annual mitigation potential of the four REDD+ activities in northeast India being 29.2 MtCO2 for 2030.

H. K. Nigam,Ajay Sharma
International Journal of Mathematics and Mathematical Sciences , 2010, DOI: 10.1155/2010/351016
Abstract: A very new theorem on the degree of approximation of the generating function by means of its Fourier-Laguerre series at the frontier point is obtained. 1. Introduction Let be an infinite series with the sequence of its th partial sums . If then we say that is summable by means (see the study by Hardy [1]), and it is written as , where is the sequence of th partial sums of the series . The Fourier-Laguerre expansion of a function is given by where and denotes the th Laguerre polynomial of order , defined by generating function and existence of integral (1.3) is presumed. We write Gupta [2] estimated the order of the function by Cesàro means of series (1.2) at the point after replacing the continuity condition in Szeg?’s theorem [3] by a much lighter condition. He established the following theorem. Theorem 1.1. If then provided that , with being the th Cesàro mean of order . Denoting the harmonic means by , Singh [4] estimated the order of function by harmonic means of series (1.2) at point by weaker conditions than those of Theorem 1.1. He proved the following theorem. Theorem 1.2. For provided that is a fixed positive constant, 2. Main Theorem The objects of present paper are as follows:(1)We prove our theorem for means which is entirely different from and harmonic means.(2)We employ a condition which is weaker than condition (1.9) of Theorem 1.2.(3)In our theorem the range of is increased to , which is more useful for application. In fact, we establish the following theorem. Theorem 2.1. If then the degree of approximation of Fourier-Laguerre expansion (1.2) at the point by means is given by provided that is a fixed positive constant and , where is a positive monotonic increasing function of such that as . 3. Lemmas Lemma 3.1 (see the study by Szeg?, 1959, [3, page 175]). Let be arbitrary and real, let and be fixed positive constants, and let Then 4. Proof of the Main Theorem Since therefore, Now, Using orthogonal property of Laguerre’s polynomial and (1.5), we have Using orthogonal property and condition (3.2) (taking for and for ) of Lemma 3.1, we get Further, using orthogonal property and condition (3.1) (taking for , 1 for , and for ) of Lemma 3.1, we get Now, since Therefore, By (4.7) and (4.9), we have, Thus, Now, we consider Finally, Combining (4.4), (4.5), (4.11), (4.12), and (4.13), we get This completes the proof of the theorem.

Recurrent Syncope in a Cancer Patient: A Case Report and Review of the Literature
Jyoti Sharma,Anne H. Dougherty
Cardiology Research and Practice , 2011, DOI: 10.4061/2011/678237
Abstract: A 59-year-old male with invasive squamous cell carcinoma of the left preauricular region, treated with several chemotherapy regimens and radiation therapy, was admitted for recurrent syncopal episodes. He was found to be suffering from neurocardiogenic reflex-mediated syncope secondary to mechanical compression of the carotid baroreceptors and glossopharyngeal nerve by the tumor. We discuss the pathophysiology of this case and the available treatment options. 1. Case A 59-year-old Caucasian male with invasive squamous cell carcinoma of the left pre-auricular region was admitted for recurrent syncope over a period of four weeks. He was previously treated with radiation therapy and two chemotherapy agents, Cisplatin and Cetuximab. He described brief prodromal symptoms of lightheadedness and diaphoresis prior to each episode. He regained consciousness in less than one minute and quickly returned to his baseline mental status. Upon arrival to the emergency room after his first episode, his pulse was 65 beats per minute (bpm) and his blood pressure was recorded as 64/42?mm?Hg. He was managed with aggressive fluid resuscitation, including three liters of intravenous fluids, and Trendelenburg positioning. After this first episode, follow-up blood pressure recordings were in the normal range within the first one to two hours. 24 hours later, he was no longer symptomatic and was back to his baseline physical and mental status. On a second occasion he was more profoundly affected, and his first systolic blood pressure recorded in the emergency room was 46 mm?Hg and his pulse ranged from 46–57?bpm. Upon presentation during this event he was confused and his blood pressure took longer to recover despite similar treatment with intravenous fluid resuscitation and Trendelenburg positioning. However, similar to the first episode, 24 hours later he was back to his baseline. On no occasion was his syncope associated with head turning or neck compression. He did have longstanding neuropathic pain located in the posterior nasopharynx and the left side of his face. As his disease had progressed, he also developed pain with swallowing; however, there was no exacerbation in his symptoms surrounding the syncopal episodes. Several events occurred while he was supine. Further testing including orthostatic blood pressure measurements, electrolyte measurements, an electrocardiogram, and echocardiogram revealed no abnormalities. A Holter monitor recording preceding one of his syncopal episodes showed sinus pauses of up to 2.1 seconds. These pauses were frequent and were associated
