Study of Low Dimensional Systems with NEGF and RMT Approach

Quantum transport has become an emerging field in research day by day. Its pure mesoscopic study. We have used two approaches NEGF & RMT. Quantum transport model is presented using the NEGF(nonequilibrium Green’s function) formalism. The non-equilibrium Green’s function(NEGF) formalism provides a natural framework for describing quantum transport. The NEGF method originated from the seminal works of Martin and Schwinger (1959), Kadanoff and Baym (1962) and others who used the methods of many-body perturbation theory to describe the distributed entropy generating processes. In our bottom-up approach we have used elastic resistors for which entropy-driven processes are confined to the contacts and problem of our system channel here can be treated within a one-electron picture by connecting contacts to the Schrodinger equation here. In recent years it has been a revival of interest in Random Matrix Theory (RMT), which has been discussed in second part of the thesis. In this thesis we have studied quantum transport corresponding to different systems like one-dimensional wire, CNT(Carbon Nanotube), GNR(Graphene Nanoribbon) and finally disordered one dimensional wire with Random Matrix Theory (RMT) approach. We have used nonequilibrium Green’s function approach in our work also. This thesis has been divided into two parts, in first part we have studied transport corresponding to CNT, GNR and other systems. In second part of the thesis we have studied disordered wire in one-dimensional case, where application wise it leads to high mobility devices. It is pure mesoscopic study and has a lot of applications in spintronic fields. Random Matrix Theory
Preparing Family Members for the Death of Their Loved One With Cancer: A Review of Literature and Direction for Future Research

This review of literature describes recently published research on preparing family members for the death of their loved one with advanced cancer and discusses directions for further research. A search was conducted among 5 electronic databases. A total of 18 articles published between January 2000 and September 2011 were identified and included in this review. The literature revealed that the current trends of research are to study (1) the awareness of family members of the impending death of their loved one and (2) the 4 dimensions of preparedness. Comprehensive studies needed are to explore family members’ preparation for the death of their loved one with advanced cancer, including the awareness and time frame of family members for the death of a loved one; their preparedness including medical, psychosocial, spiritual, and practical dimensions; and communication and support received from healthcare professionals. Expanding understanding of preparing family members for the death will enable healthcare professionals to develop innovative interventions to improve family members’ preparation for the death of their loved one and to ease their bereavement.
Evaluation Of Clinicopathological Features Of Breast Cancer According To The Molecular Subtypes

Objective: Breast cancer is the most common malignancy observed among women worldwide. Breast cancer is a heterogeneous tumor, with different responses to therapy even among tumors of similar histology and stage. In this study we aimed to compare the clinical and pathological features of breast cancer according to the molecular subtypes. Methods: We retrospectively reviewed the 292 cases with breast cancer, who were diagnosed and treated at the Izmir Tepecik Education and Research Hospital between 2011 and 2014. Descriptive and inferential analyses between different intrinsic subtypes were performed. Results: A total of 292 females with invasive breast cancer were included in this study. The mean age of the patients was 55.5±12.8 years (28-85 years) which was similar to mean ages of patients with different tumor types. We identified 90 (30.8%) cases of luminal A, 87 (29.8%) luminal B, 78 (26.7%) HER2+, and 37 (12.7%) triple negative. The mean Ki-67 proliferation index was found to be 5 (1-12) in Luminal A group, 28.4 (15-80) in Luminal B group, 24.1 (1-95) in Her2 positive group and 43 (1-85) in triple negative group. The mean follow-up period was 22.5±10.9 months. Mean mortality rate was found as 10.6% (n = 31) in all patients. The least survival rate was determined in triple negative patients (78.4%, n=29). The highest survival rate was assessed (as compatible with the literature) in the luminal A group (n= 83, 92.2%). HER2-positive cases had second highest survival rate with tailored treatment (n= 71, 91%). Conclusion: Histopathologic features or histological grade of breast cancer alone are not reliable prognostic factors. It must be always considered that breast cancer is a heterogeneous tumor. Therefore in breast cancer, tailored therapy according to the molecular subtypes of tumor, seems to provide the highest benefit for patients.

Editorial: Educational Gerontology — A Sleeping Giant Awakened

In 1989 an Educational Gerontology Interest Group was formed within the Canadian Association on Gerontology (CAG). By 1990 more than 140 members of CAG had identified with the Group and 17 papers were presented (Thornton, 1992). The interest group thrived and in 1996 the Board of CAG approved the formation of a Division of Educational Gerontology. In 1991 the National Advisory Council on Aging (NACA) published the NACA position on gerontology education. This contained 15 recommendations and highlighted service provision in the present system. NACA's recommendations included a focus on personnel needs and program development, specifically human resource projections, a national inventory of gerontology instruction, guidelines for program development, faculty development and strategies to promote student interest. There has been progress. Nationally CAG has prepared an inventory of gerontology programs (Canadian Association on Gerontology, 1994). Initiatives connected with the Educational Centre for Aging and Health in Ontario have led to the issuance of curriculum guidelines in dentistry, social work, nursing, rehabilitation science, and medicine (Ontario University Coalition for Education in Health Care of the Elderly, 1993). The NACA document also encouraged continuing education for all staff whose duties have a significant impact on the lives of seniors. It notes the need for ingenuity to meet the special circumstances of service providers in the workplace. Perhaps the message is getting through that full-day workshops off-site may not be a good fit with today's funding practices. NACA recommended that education adopt multidisciplinary perspectives, a view now widely accepted, at least in theory. It also recommended that education in Canada address the ethnocultural diversity of seniors and their families, a dimension known in the United States as ethnogeriatrics. It suggested that training in gerontology be recognized by employers and that government and the private sector support the development of education in the field of aging. Finally, it recommended programs to assist formal service providers in responding to the needs of informal caregivers and underlined the importance of advocacy by seniors. In 1992 Jim Thornton proposed a taxonomy for educational gerontology in Canada. Building on Peterson's (1980) work, Thornton argued that educational gerontology in Canada was composed of Senior Adult Education, concerned with the teaching and instruction of older adults; Gerontology Education, concerned with the teaching and instruction of youth and the non-specialist public; Academic Gerontology, concerned with teaching

Desarrollo de un sensor radioquímico para efluentes líquidos

El control dela radioactividad en agua se encuentra regulado por diversas normativas nacionales e internacionales. Actualmente, para radionucleidos emisores de particulas beta y alfa, este control se realiza mediante medidas en laboratorio a causa de la falta de instrumentacion para el analisis en continuo. En la presente tesis se ha establecido la capacidad del centelleo plastico para la deteccion de los tres tipos de emision radioactiva, alfa, beta y gamma. El centellador plastico presenta, ademas, la ventaja de que no genera residuos mixtos, residuos con propiedades toxicas y radioactivas, y que en un equipo en continuo no se consume ni requiere activos adicionales. El sensor construido en la presente tesis emplea centellador plastico e incorpora fibras opticas para enviar la senal a una posicion remota, lo que permite el control en continuo, en remoto y en tiempo real del contenido de radionucleidos en un efluente liquido.
58. A case of synchronous pleomorphic adenomas arising in the parotid and an intraparotid lymph node

Pleomorphic adenoma is a benign salivary gland tumour that commonly arises in the parotid gland. There are very few reported cases of pleomorphic adenomas arising in lymph nodes. We present an interesting and rare case of this benign entity occurring synchronously in the parotid and an intraparotid lymph node of a 31 year old woman. A brief review of the literature will be included.
CHRONIC INTERMITTENT HYPOXIA INDUCES HIGH BLOOD PRESSURE AND OXIDATIVE STRESS IN RATS

Objectives Chronic intermittent hypoxia (CIH) is a typical feature of obstructive sleep apnoea (OSA) and is associated with oxidative stress and systemic endothelial dysfunction, which leads to systemic hypertension and other cardiovascular diseases. The objective of the present study was to examine whether CIH may induce oxidative stress and high blood pressure in Wistar rats. Methods Forty male Wistar rats, 8 weeks of age, were subjected either to CIH (nadir FIO2=8%±0.5%, 180 s/cycle, 20 cycles/h, 8 h per day diurnally) or intermittent air (control conditions) for 28 consecutive days. Arteria caudilis blood pressure of rats were recorded at day 0, 7, 14, 21 and 28 d by Softron sphygmomanometer; Blood and tissues was collected before and after exposure. Results There was no differences in blood pressure between groups at baseline. Compared with the baseline, CIH significantly increases the blood pressure (p<0.01). SBP of CIH rats were higher than that of Control rats after 3 weeks of hypoxia exposure (124.5±5.2 mm Hg vs 113.6±10.2 mm Hg, p<0.01); and after 4 weeks, SBP (127.6±5.3 mm Hg vs 118.0±3.3 mm Hg, p<0.05) and DBP (82.9±4.5 mm Hg vs 73.3±10.3 mm Hg, p<0.05) of CIH rats were both increased significantly. The tissue of myocardium and vessels in CIH did not show obvious hypoxic change. But the expression of SOD, MDA in heart tissues in CIH was obviously increased compared with that in Control group (p<0.05); The levels of plasm ET-1 concentration in CIH rats was increased following the time, and all higher than that in Control rats (p<0.05). Conclusions From these results we conclude that CIH do increase blood pressure in Wistar rats. And increased blood pressure maybe associated with oxidative stress and increased level of ET-1.
Mohnarin of 2008: surveillance results of national bacterial drug resistance.

OBJECTIVE To get information about bacterial resistance and its epidemic trend for clinical reference in the use of antibacterial agents.METHODS All of the bacterial susceptibility results from 89 tertiary care hospitals around China from Jan 1 to Dec 31,2008 were collected by unified protocol and the data were analyzed by software WHONET 5.4. The Disc-diffusion or automatic clinical microbiological system method was used for the bacterial sensitivity.RESULTS A total of 157 813 bacterial isolates and their antibacterial susceptibility data were collected during the survey period in 89 tertiary hospitals,which included 50 856 (31.7%) Gram-positive bacterial strains and 106 957(68.3%) Gram-negative bacterial strains.Staphylococcus (32 378 strains),Enterococcus (12 127 strains) and Streptococcus (5138 strains) were the top three Gram-positive isolates,while Escherichia coli (26 957 strains),Pseudomonas aeruginosa (18 347 strains) and Klebsiella pneumoniae (16 396 strains) were the most common Gram-negative isolates.The incidences of meticillin-resistant Staphylococcus aureus (MRSA) and S.epidermidis were 67.6% and 83.2%,respectively;3.8% of S.pneumoniae were penicillin resistant.More than 40.0% of E.coli and other enterobacteria were resistant to most of the antibiotics,quinolone-resistant rate of E.coli was over 70.0% and 56.0% of the E.coli produced extended spectrum β-lactamases (ESBLs),the drug resistance rates of E.coli against the third and fourth generation cephalosporin (including ceftazidime) were higher than 60.0%. The drug resistance rates of non-fermented bacteria to meropenem were 24.8%-41.7%,and the drug resistance rate of Acinetobacter baumannii was higher than that of P.aeruginosa. CONCLUSION The clinical isolation phenomenon of bacterial drug resistance is universal and the drug resistance rate keeps an upward tendency in China,especially MRSA,ESBLs-producing enterobacteria and multidrug-resistant non-fermented bacteria are most common.
Sudden infant death syndrome and sleeping position in pre-term and low birth weight infants:An opportunity for targeted intervention

Aims: To determine the combined effects of sudden infant death syndrome (SIDS) risk factors in the sleeping environment for infants who were “ small at birth” (pre-term ( 37 weeks), low birth weight ( 2500 g), or both). Methods: A three year population based, case-control study in five former health regions in England (population 17.7 million) with 325 cases and 1300 controls. Parental interviews were carried out after each death and reference sleep of age matched controls. Results: Of the SIDS infants, 26% were “ small at birth” compared to 8% of the controls. The most common sleeping position was supine, for both controls (69% ) and those SIDS infants (48% ) born at term or ≥ 2500 g, but for “ small at birth” SIDS infants the commonest sleeping position was side (48% ). The combined effect of the risk associated with being “ small at birth” and factors in the infant sleeping environment remained multiplicative despite controlling for possible confounding in the multivariate model. This effect was more than multiplicative for those infants placed to sleep on their side or who shared the bed with parents who habitually smoked, while for those “ small at birth” SIDS who slept in a room separate from the parents, the large combined effect showed evidence of a significant interaction. No excess risk was identified from bed sharing with non-smoking parents for infants born at term or birth weight ≥ 2500 g. Conclusion: The combined effects of SIDS risk factors in the sleeping environment and being pre-term or low birth weight generate high risks for these infants. Their longer postnatal stay allows an opportunity to target parents and staff with risk reduction messages.
Development and Application of a Framework for Emerging Infectious Disease Intelligence in Lower Resource Settings

In 2005, World Health Organization member countries agreed to the revised International Health Regulations which require countries to detect, report, and respond to any event that may represent a public health emergency of international concern. Forecasting the risk posed by hazards, including incidents in animal populations, requires an intelligence-based approach. We propose an emerging infectious disease intelligence framework informed by literature from the fields of surveillance, epidemic intelligence, and military intelligence. This framework highlights the need for situational awareness and can be used to assess emerging infectious disease intelligence capacity in lower resource settings. To illustrate the utility of this framework we applied it to the Infectious Disease Surveillance and Analysis System, a mobile phone-based surveillance pilot project supplementing diagnostic laboratory-based surveillance in Sri Lanka. Application of the framework was feasible and useful in illuminating the strengths and deficits in the current surveillance infrastructure in Sri Lanka for emerging infectious disease early warning. The approach also demonstrated how a mobile phoned-based system could improve Sri Lanka’s emerging infectious disease intelligence capabilities. Finally, the framework allowed us to recommend steps to take in order to strengthen Sri Lanka’s emerging infectious disease early warning capacity, enabling more timely and complete identification of events in the animal population that could pose a human health risk.
Views of Iranian prison staff towards needle-exchange program in prison

Abstract Aims: Prison staff members have a core role in the provision of harm reduction strategies in prison. This study aimed to evaluate the attitudes of prison directors, managers and health staff toward Needle Exchange Program (NEP) among people who inject drugs in Iranian prisons. Methods: With a grounded theory design, this qualitative study was conducted in 2011 in Iran. The study population included directors of provincial prison organisations, prison managers, heads of health departments in prisons, prison health officers, physicians, counsellors and healthcare workers in prisons. Participants’ responses were collected via focus group discussions. Results: Attitudes of the participants could generally be categorised in three including: Health-related aspects; Behavioural and social aspects; and Legal, organisational and financial aspects. Those who were in line with the existence of NEP in prisons mentioned some pre-requisites for supporting this program in prisons. Conclusion: Positive and negative views of Iranian prison staff toward NEP in prisons suggest that there are many obstacles to the provision of harm reduction strategies in prison. Consideration of socio-cultural parameters of the target community as well as combination of NEP and other harm reduction strategies might help to improve the effectiveness of harm reduction in prisons.
Histological Analysis of Collagen Fibers in Patients with Diabetes Mellitus and Periodontal Disease

The researchers suggest that diabetes increases the degradation of the newly synthesized collagen from the conjunctive tissue. The altered metabolism of the collagen may predispose the diabetic patients not only to periodontal disease, but also to some other anomalies such as defective healing. The purpose of the study was to go through a histological analysis of the collagen fibers from the chorion in patients with diabetes mellitus and periodontal disease. Materials and Methods: In our study we examined a total of 68 patients diagnosed with diabetes mellitus type 1 and 2. In these patients we achieved simple gingivectomy or tooth extraction in order to obtain gingival tissue fragments. The preparations included at paraffin and then stained with Hematoxylin-Eosin and trichromic after Goldner-Szeckeli method. Results: In the patients with diabetes mellitus with an evolution of less than 10 years the collagen fibers appeared as dissociated by the inflammatory cells that were inserted among them. It was also noted the fragmentation of collagen fibers and sometimes even their lysis with subepithelial connective tissue disorganization. In patients with diabetes for over 10 years there has been noticed a plentiful collagen sclerosis, zones of collagen hyalinization with an increased number of fibrocytes. Conclusion: The extracellular matrix is altered in the investigated patients with destructive lesions of collagen or collagen sclerosis.
A Rare Cause of Nosocomial Infections Associated with Nephrolithiasis; Sphingomonas Paucimobilis

Sphingomonas paucimobilis is a gram negative, nonfermentative, oxidase positive, very slow acting bacillus. In species of Sphingomonas, S. paucimobilis, known as a pathogen, is a rare cause of nosocomial infection. S. paucimobilis is isolated from distilled water, labs, nebulizers, mechanical ventilators and dialysis liquids in hospital. S. paucimobilis is reported to have caused infection among the patients which have chronic disease or a weak immune system, and alcoholics and drug users. In this case we presented a three year old girl patient, diagnosed with nephrolithiasis, who had S. paucimobilis her blood culture which was taken because of fever, chills and right costovertebral angle sensitivity on the 11th day.
