Cyclic codes of length 2k over Z8  [PDF]
Arpana Garg, Sucheta Dutt
Open Journal of Applied Sciences (OJAppS) , 2012, DOI: 10.4236/ojapps.2012.24B025
Abstract: We study the structure of cyclic codes of length 2k？over Z8？for any natural number k.？ It is known that cyclic codes of length 2k？over Z8？are ideals of the ring R=Z8[X]/. In this paper we prove that the ring R=Z8[X]/ is a local ring with unique maximal ideal, thereby implying that R is not a principal ideal ring.？ We also prove that cyclic codes of length？2k？over Z8？are generated as ideals by at most three elements.

BMC Pregnancy and Childbirth , 2011, DOI: 10.1186/1471-2393-11-76
Abstract: Using the pregnancy surveillance infrastructure from a large community trial in northwest rural Bangladesh, we nested a qualitative study to document barriers to timely receipt of medical care for severe obstetric complications. We conducted 40 semi-structured, in-depth interviews with women reporting severe acute obstetric complications and purposively selected for conditions representing the top five most common obstetric complications. The interviews were transcribed and coded to highlight common themes and to develop an overall conceptual model.Women attributed their life-threatening experiences to societal and socioeconomic factors that led to delays in seeking timely medical care by decision makers, usually husbands or other male relatives. Despite the dominance of male relatives and husbands in the decision-making process, women who underwent induced abortions made their own decisions about their health care and relied on female relatives for advice. The study shows that non-certified providers such as village doctors and untrained birth attendants were the first-line providers for women in all categories of severe complications. Coordination of transportation and finances was often arranged through mobile phones, and referrals were likely to be provided by village doctors.Strategies to increase timely and appropriate care seeking for severe obstetric complications may consider targeting of non-certified providers for strengthening of referral linkages between patients and certified facility-based providers. Future research may characterize the treatments and appropriateness of emergency care provided by ubiquitous village doctors and other non-certified treatment providers in rural South Asian settings. In addition, future studies may explore the use of mobile phones in decreasing delays to certified medical care during obstetric emergencies.Annually, approximately 9.5 million women around the world suffer from pregnancy-related complications, and over 300,0

Abstract: This analysis utilized data from a large population-based cohort trial in northwest rural Bangladesh. To conduct verbal autopsies of women who died while under study surveillance, physicians interviewed family members to elicit the biomedical symptoms that the women experienced as well as a narrative of the events leading to deaths. We performed qualitative textual analysis of verbal autopsy narratives for 250 women of reproductive age who died from non-communicable diseases between 2001 and 2007.The majority of women (94%) sought at least one provider for their illnesses. Approximately 71% of women first visited non-certified providers such as village doctors and traditional healers, while 23% first sought care from medically certified providers. After the first point of care, women appeared to switch to medically certified practitioners when treatment from non-certified providers failed to resolve their illness.This study suggests that treatment seeking patterns for non-communicable diseases are affected by many of the sociocultural factors that influence care seeking for pregnancy-related illnesses. Families in northwest rural Bangladesh typically delayed seeking treatment from medically certified providers for NCDs due to the cost of services, distance to facilities, established relationships with non-certified providers, and lack of recognition of the severity of illnesses. Most women did not realize initially that they were suffering from a chronic illness. Since women typically reached medically certified providers in advanced stages of disease, they were usually told that treatment was not possible or were referred to higher-level facilities that they could not afford to visit. Women suffering from non-communicable disease in these rural communities need feasible and practical treatment options. Further research and investment in adequate, appropriate care seeking and referral is needed for women of reproductive age suffering from fatal non-communicable dise

The Role of Library and Information Science Education in the Development of Community Health Information Services for People Living with HIV/AIDS: Perspectives of Directors and Managers of Public Libraries  [PDF]
Bharat Mehra, Adrienne Dessel
World Journal of AIDS (WJA) , 2011, DOI: 10.4236/wja.2011.13012
Abstract: This article identifies the role of library and information science (LIS) education in the development of community health information services for people living with HIV/AIDS (PLWHA). Preliminary findings are presented from semi- structured qualitative interviews that were conducted with eleven directors and managers of local branches in the Knox County Public Library (KCPL) System that is located in the East Tennessee region in the United States. Select feedback reported by research participants is summarized in the article about strategies in LIS education that can help local public librarians and others in their efforts to become more responsive information providers to PLWHA. Research findings help better understand the issues and concerns regarding the development of digital and non-digital health information services for PLWHA in local public library institutions.
Measurement of Radioactivity of 238U, 226Ra, 232Th and 40K in Soil of Different Geological Origins in Northern India  [PDF]
Rohit Mehra, Manmohan Singh
Journal of Environmental Protection (JEP) , 2011, DOI: 10.4236/jep.2011.27110
Abstract: Radioactivity of the nuclides 238U, 226Ra, 232Th and 40K was measured in soil by γ-ray spectrometry using HPGe detector. A criterion was set in order to analyse soil samples from plain, semi-hilly and hilly areas in northern India. More than three γ-ray energy peaks were used for the determination of 226Ra and 232Th activity concentrations to obtain more accurate results. Some of these peaks have interfering energies, which was caused by the limited resolution of the detector, but they were resolved theoretically and used in the analysis because of their significance in reducing the random error to its minimum level. Relationships between the measured radionuclides have been discussed elaborately. Radionuclides 238U and 226Ra were found in disequilibrium with ratio of specific activities 238U/, 226Ra) less than unity for most of the samples. In some cases this disequilibrium may be significant enough to modify the γ-ray dose factors.
Gap Functions and Error Bounds for Set-Valued Vector Quasi Variational Inequality Problems  [PDF]
Rachana Gupta, Aparna Mehra
Applied Mathematics (AM) , 2017, DOI: 10.4236/am.2017.812135
Abstract:
One of the classical approaches in the analysis of a variational inequality problem is to transform it into an equivalent optimization problem via the notion of gap function. The gap functions are useful tools in deriving the error bounds which provide an estimated distance between a specific point and the exact solution of variational inequality problem. In this paper, we follow a similar approach for set-valued vector quasi variational inequality problems and define the gap functions based on scalarization scheme as well as the one with no scalar parameter. The error bounds results are obtained under fixed point symmetric and locally α-Holder assumptions on the set-valued map describing the domain of solution space of a set-valued vector quasi variational inequality problem.

Abstract: Hepatitis E virus (HEV) infection is severe during pregnancy, with a pregnant case fatality rate around 30%. In Bangladesh, plasma samples from 1,100 women during the first trimester (TM) and third TM of pregnancy and 3 months postpartum (PP) were tested for anti-HEV IgG. During this time, 40 women developed antibody responses to HEV. These seroconverters are classified as the cases (incidence = 46 infections per 1,000 person-years). All except one seroconversion occurred between the third TM and 3 months PP. The cases and 40 matched non-seroconverters (controls) underwent analysis of a panel of 10 cytokines, 12 vitamins and minerals, and two markers of inflammation. Throughout pregnancy, seroconverting cases displayed higher concentrations of both pro- and anti-inflammatory cytokines compared with the non-seroconverting controls, even prior to infection. In the first TM, seroconverters had lower circulating zinc concentrations (P = 0.03), an increased prevalence of vitamin D deficiency (25-hydroxy vitamin D [25(OH)2D] < 50 nmol/L, P = 0.08), and anemia (hemoglobin < 110 g/L, P = 0.05) compared with controls. There were no differences in C-reactive protein or α-1-acid glycoprotein. Antecedent micronutrient deficiencies may lead to dysregulated cytokine expression and immunologic compromise, increasing the risk of HEV infection, especially during pregnancy. This exploratory analysis reveals potential novel associations that deserve further study

A Rare Case Report of Amlodipine-Induced Gingival Enlargement and Review of Its Pathogenesis
Sanjeev Joshi,Sucheta Bansal
Case Reports in Dentistry , 2013, DOI: 10.1155/2013/138248
Abstract: Gingival enlargement is a common clinical feature of gingival and periodontal diseases. It is an unwanted side effect of certain systemic drugs given for nondental treatment. It is being reported with three main groups of drugs like calcium channel blockers (CCBs), immunosuppressants, and anticonvulsants. Among calcium channel blockers, nifedipine causes gingival hyperplasia in about 10% of patients, whereas the incidence of amlodipine-, a third generation calcium channel blocker, induced gingival hyperplasia is very limited. There are very few reports of amlodipine-induced gingival enlargement at a dose of 5？mg. We report a case of amlodipine-induced gingival enlargement in a 45-year-old hypertensive patient taking amlodipine at a dose of 5？mg. 1. Introduction Drug-induced gingival enlargement was first reported in 1939 by Kimball with chronic usage of the antiepileptic drug phenytoin [1]. Currently, more than 20 prescription medications are associated with gingival enlargement [2]. Drugs associated with gingival overgrowth can be broadly categorized into three major groups according to their therapeutic actions, namely, anticonvulsants, immunosuppressants, and calcium channel blockers [3, 4]. Amlodipine is a new dihydropyridine calcium channel blocker that is used in the management of both hypertension and angina. Ellis et al. [5] first reported gingival sequestration of amlodipine and amlodipine-induced gingival overgrowth. Since then, very few cases of amlodipine-induced gingival hyperplasia have been reported in the dental literature although there are numerous reports of nifedipine- (another member of calcium channel blockers) induced gingival overgrowth till date. There are less data on reports of hyperplasia with amlodipine at a dose of 5？mg, even after taking it for more than 6 months [6, 7]. But, in the present case, the gingival hyperplasia occurred at a dose of 5？mg within 6 months of use. 2. Case Report A 45-year-old male patient came to the department with the chief complaint of loose teeth in upper and lower front jaw regions since 1 year with swollen and bleeding gums. Patient first noted bead like nodular growth over the gums which progressively enlarged to the present size covering almost entire teeth interfering with further cleaning of teeth. The patient was hypertensive since 1.5 years and was under medication Coronol-AM (atenolol, 50？mg + amlodipine, 5？mg) once daily. He denied the history of any adverse habits. The patient was moderately built and nourished with no signs of anaemia and jaundice and noncyanosed. His vital signs
