Secondary terms in the number of vanishings of quadratic twists of elliptic curve L-functions

Mathematics , 2005,
Abstract: We examine the number of vanishings of quadratic twists of the L-function associated to an elliptic curve. Applying a conjecture for the full asymptotics of the moments of critical L-values we obtain a conjecture for the first two terms in the ratio of the number of vanishings of twists sorted according to arithmetic progressions.
Treatment Options of Macular Edema Secondary to Retinal Vein Occlusion (RVO): A Review  [PDF]
Aradhana Pokharel, Jie Luan
Open Journal of Ophthalmology (OJOph) , 2019, DOI: 10.4236/ojoph.2019.92009
Abstract: Retinal Vein Occlusion (RVO) is a common retinal vascular disease secondary to diabetic retinopathy resulting in permanent loss of vision despite available treatment options. Main vision impending complication of retinal vein occlusion is macular edema. Laser photocoagulation has been an established method for treating macular edema for many years but nowadays intravitreal injection of Anti-Vascular endothelial growth factors (Ranibizumab, Aflibercept Bevacizumab and Pegaptanib sodium) is the treatment of choice for macular edema from retinal vein occlusion. Intra-vitreal corticosteroids Triamcinolone Acetonide and Dexamethasone implant, are also being used to treat in some macular edema cases but with higher rates of side effects. Numerous surgical methods have been attempted for treating RVO and preventing macular edema; they include pars plana vitrectomy, radial optic neurotomy, laser induced chorioretinal anastomosis, and arteriovenous sheathotomy. Surgical methods supposedly relieve compression of the central retinal vein, altering the pathophysiology of vein occlusion at the level of the lamina cribrosa thus improving blood flow and oxygenation. But limitations result from its complications.
Nanomechanical Analysis of Hybrid Silicones and Hybrid Epoxy Coatings—A Brief Review  [PDF]
Atul Tiwari
Advances in Chemical Engineering and Science (ACES) , 2012, DOI: 10.4236/aces.2012.21005
Abstract: This review article is written on the investigations of nanomechanical properties of coatings by using nanoindentation techniques. The focus is on the studies that were conducted on epoxy polymer, silicones and their hybrid materials. The article describes a large number of developmental studies that are conducted on coatings. Materials properties such as nanoindentation hardness, modulus, scratch, wear and viscoelastic behavior have been described. Moreover, the article summarizes various studies that mention the use of different nanoparticles in coating formulations that could improve the mechanical strength and service life span of the coatings. The mode and mechanism of material’s failure has been outlined and discussed.
Virtual Worlds for Student Engagement  [PDF]
Atul Sajjanhar
Creative Education (CE) , 2012, DOI: 10.4236/ce.2012.326118
Abstract: In this paper, we study the scope of virtual worlds for student engagement in higher education. The motivation for the study is the gap in opportunities for interactivity that exist for off-campus students compared with on-campus students. A student taking a course at a university, while located in a different geographic location, has limited opportunity for student-student and student-teacher interaction; this effects student engagement significantly. We conduct a feasibility analysis for engaging students in a virtual world; Second Life is used as the test-bed to create the virtual world environment. We present preliminary findings, the promises and the limitations of Second Life as an immersive environment for engaging students.

Multifocal Tubercular Osteomyelitis Involving Bilateral Symmetrical Second Metacarpals
R Pokharel
Journal of Institute of Medicine , 2012, DOI: 10.3126/joim.v34i2.9054
Abstract: Skeletal tuberculosis involving small bones of the hand is less common. We report a case, 6 year old boy, of bilateral symmetrical tubercular osteomyelitis of second metacarpals. He presented with gradually increasing swellings over bilateral hands over duration of one month. There was no other significant history relating to tuberculosis. Hand X-rays showed expansive lesions of bilateral second metacarpals. Thick pus and necrotic tissue was removed from both the swelling and from the bone. Presence of typical tubercular granuloma in the histopathological examination confirmed the diagnosis. The boy was treated with antitubercular drugs and improved after completion of anti-tubercular treatment. Tuberculosis can present in different ways, and should be kept as one of the possible diagnosis of several bony pathologies including metacarpals and phalanges, especially in this part of the world where tuberculosis endemic.

Spontaneous delivery or manual delivery of the placenta during caesarean: A randomized controlled trial
SM Pokharel
Journal of College of Medical Sciences-Nepal , 2011, DOI: 10.3126/jcmsn.v7i2.6676
Abstract: The study was done to compare the blood loss and the time between spontaneous delivery and manual removal of the placenta during caesarean section. We prospectively randomized and compared outcomes of 100 gravid women with manual (n=50) and spontaneous (n=50) placental delivery at caesarean section. Blood loss was measured after placental deliverey at caesarean and was greater in the manually delivered group (100.9 ± 22.5 ml) than in the spontaneous delivery group. (55.11 ±21.07 ml) P< 0.001. The mean interval during the delivery of the newborn and the placenta is longer in spontaneous delivery group (62.02 vs. 50.5 seconds), but the mean duration of the operation was similar. Spontaneous delivery of the placenta as compared to manual expression significantly reduces the blood loss without increasing the operating time.
Changing Relations between High Castes and Tamang in Melamchi Valley
Binod Pokharel
Dhaulagiri Journal of Sociology and Anthropology , 2010, DOI: 10.3126/dsaj.v4i0.4513
Abstract: This paper is about the processes of transformation of social relations between high caste groups and Tamang in Melamchi Valley for the period of 1980-2010. Development interventions made by government of Nepal and (I) NGOs, a decade long undergoing Melamchi Water Supply Project and labor migration are major factors for ongoing changes in the study area. Spread of literacy classes and primary education, availability of credit institutions, introduction of modern farming, road networks, seasonal out migration from the area, etc. primarily define new relations among the groups. Borrowing and lending money were one of the basis of high caste and Tamang relation in past. The latter was regarded as borrower loan from first one. Before 1980s, money and agriculture commodities were controlled by few rich and high castes people. Cash income from various sources made enable the Tamang to stand on an equal footing with high caste people. Open political economy and liberal policy for issuing pass port in 1990s and after that encourage the people to diversify the destination of seasonal migration from India to Gulf countries and East Asia. Various processes of socio-economic and political changes led to local peoples to seek their position and identity in the changing context. Discourse of Tamang, high castes and Dalit entered into the Valley along with the development resources of (I)NGO and political movements of the country. This made possible to Tamang and other disadvantage groups to define and redefine their ethnic identity.
