Authors: Zhang Zheyuan , Xie Yonghui , Zhang Di , Xie Gongnan 
Published: April 2017

Abstract
Porous cavity technology is one of the effective ways to improve local flow structures and thus the overall heat transfer of heat exchanging devices. In the present investigation, the flow characteristics and heat transfer in a microchannel heat sink with teardrop dimples/protrusions are studied with a numerical method. The working substances are Al2O3-water nanofluids, which are defined by power-law shear-thinning model. The relative depth and positive eccentricity of dimples/protrusions arranged in the microchannels are 0.2 and 0.3 respectively. The inlet velocity varies in the range of 1.41 m⋅s−1 to 8.69 m⋅s−1 and the volume fraction ranges from 0.5% to 3.5%. The effects of the flow and heat transfer characteristics are investigated by analyzing the limiting streamlines structures and temperature distributions. The overall thermal performance is evaluated by parameters of Fanning friction factor, Nusselt number and thermal performance. It is shown that the combination of teardrop dimple/protrusion structure and Al2O3-water nanofluids could effectively strengthen heat transfer with low pressure loss. Moreover, in order to obtain the best overall thermal performance, working substances with volume faction of 3.5% is preferred for the proposed microchannel structure.

A obra Recordações de Teatro, escrita pelo autor, jornalista, dramaturgo, diretor e empresário português Antonio de Sousa Bastos (1844-1911), assemelha-se a um dicionário biográfico, contendo informações sobre uma lista numerosa de artistas, não só reconhecidos na cena teatral portuguesa e brasileira, mas também relevantes mundialmente. Na presente análise, atentamo-nos para os procedimentos da escrita biográfica de uma grande variedade de nomes registrados na obra e, por isso, livrados do esquecimento. Por meio da leitura desses textos biográficos, pode-se constatar também o fluxo cultural entre Brasil e Portugal nos séculos XIX e XX, promovido por uma quantidade numerosa de artistas que cruzavam o Atlântico nos dois sentidos da rota.********************************************************************Memory and immortality in the memoirs of Sousa BastosAbstract: Recordações de teatro, a work written by the Portuguese author, journalist, playwright, director and businessman, Antonio de Sousa Bastos (1844-1911), resembles a biographical dictionary, containing information about a large list of artists, not only recognized in the scenario of both Portuguese and Brazilian drama, but also globally relevant. In the analysis we develop hereby, we aim at studying the procedures of biographical writing of a variety of names registered in the work of Sousa Bastos and, therefore, salvaged from oblivion. By reading those biographical texts, one can also observe the cultural exchange between Brazil and Portugal in the nineteenth and twentieth centuries, promoted by a large number of artists who crossed the Atlantic in both directions of the route.Keywords: archive; biography; memory; Portuguese drama; Sousa Bastos.
A poesia nas histórias da literatura goesa de língua portuguesa
Authors: Garmes Helder 
Published: April 2017

A ex-colônia portuguesa de Goa, na Índia, teve uma significativa e hoje pouco conhecida produção poética em língua portuguesa. Ainda que parcamente estudada, mereceu a atenção de alguns historiadores e críticos. O presente artigo realiza um percurso por esses textos históricos e críticos que procuraram traçar um panorama da poesia goesa de língua portuguesa. Pretende-se reunir neste trabalho as poucas tentativas de se narrar essa história e, assim, sistematizar a historiografia acerca dessa poesia e chegar a delinear um panteão mais preciso desses poetas nos séculos XIX e XX. Busca-se também avaliar sumariamente até que ponto tais tentativas foram bem-sucedidas e que diferentes perspectivas assumiram. Finalmente, nosso intuito é o de sugerir uma nova abordagem para a reescritura dessa história.********************************************************************Poetry in the Histories of Goan Literature in PortugueseAbstract: Goa, the former Portuguese colony in India, had a relevant but little known poetical production in the Portuguese language. Still, though little tudied, it has received some attention from historians and critics. In this context, this article aims at tracing the itinerary of these historical and critical texts that bring a panorama of Goan poetry in Portuguese. This paper also analyzes the very few attempts made so far at narrating this poetical history and, consequently, also has as its objective to contribute to the systematization of the historiography on Goan poetry in Portuguese and the creation of a more accurate pantheon of these poets during 19th and 20th Centuries. It is also the aim of this work to briefly appraise to what an extent these attempts have been successful as well as the varied perspectives from which they have been made. Finally, our intention is to suggest a new approach for the rewriting of this literary history.Keywords: Poetry; Goan Literature in Portuguese; Indo-Portuguese Literature; History of Literature.
Antidepressants-a possibly risk factor for cataract development: a cross-sectional study
Authors: Raj Rajnish , Raj Anuradha , Garg Rohit 
Published: April 2017

Background: Few studies have reported the role of antidepressants as cataractogenic in humans.Methods: It’s a hospital based descriptive, cross-sectional study. 45 Patients were screened for antidepressant use and diminution of vision, 6 were dropped out. 39 patients with 78 eyes were finally enrolled. They were divided into two goups i.e., Group-I, with cataract (N=53) and Group-II, without cataract (N=25). Three clusters of antidepressants were assessed e.g., SSRI, SNRI and TCA with therapeutic dose (TD) and non-therapeutic dose (NTD) range. Psychiatric illness was diagnosed on DSM-5 and severity of depression on HAM-D. Best corrected visual acuity (BCVA) was converted from Snellen units to logarithm of minimal angle of resolution (log MAR) for statistical analysis. Cataract changes in eyes were seen on slit-lamp and classified on Lens opacities classification system-III (LOCS-III) criteria.Results: A total 78 eyes of thirty-nine (39) patients were evaluated. Thirty (38.46%) and forty-eight (61.53%) eyes belonged to males and females, respectively. Mean age of males (n=7) was 41.8±2.3 years and females (n=32) 40.2±1.0 years. In Group-I, out of (N=53) eyes that developed cataract 33 were females (62.26%) as compared to males 20 (37.7%). Group -II, out of (N=25) eyes, females without cataract were 15 (60%) as compared to males 10 (40%). Therapeutic dose (TD) of antidepressants (AD) in Group-I had more cataract 37 (69.81%) as compared to non-therapeutic dose (NTD) 16 (30.1%). Most of the eyes with cataract 35 (66.03%) had AD exposure of more than 1 year that was possibly associated with increased risk of cataract development (OR 2.10; 95% CI, 0.79-5.55). Amongst users of antidepressants, SSRI was associated with increased risk of cataract development (OR 2.4; 95% CI, 0.72–7.94) with a female preponderance (OR 1.1; 95% CI, 0.41–2.91). Maximum number of eyes 34 (64.15%) that developed cataract had BCVA of ≥6/12 and minimum of 2 (3.77%) eyes had BCVA of ≤6/36. LOCS-III revealed 38 (71.69%) eyes (71.69%) having peripheral cortical cataract and 15 (28.30%) posterior sub-capsular cataract.Conclusions: There is a possible risk of association of cataract amongst user of antidepressants. The AD use of more than 1 year or longer had increased risk for development of cataract with a female preponderance. The highest risk was observed in the users of SSRI as compared to SNRI and TCA. Treatment exposure with antidepressant was longer for mild depression having more than two episodes.

Published: April 2017

Background: India, a developing country, faces many challenges in rendering health needs to its countrymen. The influence of culture is seen in every discipline of health and medical practices, and dentistry is no exception. This study was performed to investigate the existence of myths and taboos in dentistry, to assess the variation of these myths across various demographic aspects and socio-economic status, to co-relate the existence of myths with the oral health of the subject and to impart education to the people regarding abolishing the myth as that will be a hindrance towards a healthy life in patients. Methods: The study had a cross-sectional design, used a structured questionnaire and was conducted to assess the existence of dental myths and taboos and to determine its correlation with the OHIS index of the patients. Statistical analysis software SPSS V 16.0 was used. Descriptive & inferential statistical analysis was performed on categorical and continuous data. Chi-square, independent sample T tests and ANOVA test were used to compare the distribution of caries and OHI-S between different groups. P value less than 0.05 (p<0.05) was considered to be significant. Socioeconomic status was also calculated.Results: In the present study it was found that the there was almost an equal distribution of prevalence of myths in the educated as well as uneducated patients .Also the ratio of existence of myths was found higher in females as compared to males.Conclusions: Existence of myths and taboos regarding dental health has started decreasing among the urban population due to the widespread of awareness regarding dentistry.But still there is prevalence of some myths in the patients having primary education as compared to patients having secondary and tertiary education. If community is educated about proper prevention and cure, the myths relating dental concepts will vanish from the society and over all dental health status of the community will improve.

Published: April 2017

Background: Approximately 30% of women of reproductive age experience excessive blood loss during menstruation. In 50% of cases, menorrhagia has no underlying pathology. However, until recently, the only permanent cure for menorrhagia was hysterectomy. In this study we aim to determine the correlation of vascular endothelial growth factor (VEGF) expression with markers of endometrial endothelial cell proliferation like proliferating cell nuclear antigen (PCNA) and Cluster Determination (CD34).Methods: A total of 100 patients with history of menorrhagia were selected for study. Double Immunohistochemistry was performed on these endometrial biopsy sections. Proliferating endothelial cells were identified by an immunohistochemical double staining technique with PCNA and CD34. VEGF expression was also seen in endometrial biopsy.Results: In general, expression of both VEGF and PCNA was more in functional layer than basal layer in both menorrhagic patients as well as non menorrhagic patients. When glandular cytoplasmic VEGF expression was compared with PCNA the association was statistically significant whereas completely opposite findings was seen with glandular luminal surface VEGF positivity but the association was statistically significant. In secretory phase (p-value<0.001) there was highly statistically significant association in PCNA grading with glandular luminal surface VEGF positivity whereas when we correlated PCNA with cytoplasmic glandular VEGF in secretory phase it was statistically significant (p-value<0.001).Conclusions: The endothelial proliferation was significantly higher in menorrhagia patients during late secretory phase of cycle than controls. We were able to demonstrate increased endothelial proliferation in patients in the premenstrual part of cycle.

Published: April 2017

Background: Specific learning disability (SLD) is an important cause of academic underachievement among children, which often goes unrecognized, due to lack of awareness and resources in the community. Not much identifiable data is available such children, more so in Indian context. The objectives of the study were to study the demographic profile, risk factors, co-morbidities and referral patterns in children with specific learning disability.Methods: The study has a descriptive design. Children diagnosed with SLD over a 5 years’ period were included, total being 2015. The data was collected using a semi-structured proforma, (based on the aspects covered during child’s comprehensive assessment at the time of visit), which included socio-demographic aspects, perinatal and childhood details, scholastic and referral details, and comorbid psychiatric disorders.Results: Majority of the children were from English medium schools, in 8-12 years’ age group, with a considerable delay in seeking medical help, were referred mostly by the teachers for academic issues. Most of them had all the three disabilities-dyslexia, dysgraphia and dyscalculia. 38.56% of children had ADHD. Psychological maternal stress, developmental issues and various co-morbidities were accompanying in many cases, of which speech delay and fine motor issues were more in children having comorbid ADHD.Conclusions: Awareness, early identification and referral to appropriate services is crucial to deal with the challenge of learning disability. Health professionals should look for early signs in routine visits of children and co-morbidities, particularly ADHD, should be adequately taken care of. Role of media and education system is crucial for its destigmatization in community.

Authors: Bhatnagar Shrish , Srivastva Geetika 
Published: April 2017

Background: Rotavirus is a common cause of acute watery diarrhea in under 5 years’ children and it may cause severely dehydrating disease in an unvaccinated child. Methods: A Cross sectional study including children aged 0-5 years presenting with complaints of acute watery diarrhea with or without fever at Department of Paediatrics, Eras Lucknow Medical College and Hospital, Lucknow (Uttar Pradesh).Results: Among 399 patients of acute diarrhea, 385 were discharged and 14 took leave against medical advice. No mortality was reported in this study. Out of 399 patients enrolled 161 (40.4%) were rota virus positive on ELISA assay with mean age 18.65 months. (p=0.028). Rotavirus positivity rate was higher among those having decreased urine (p <0.001), severe dehydration (p <0.001), those with mix/formula feed (89.3%) as compared to those having exclusive breastfeeding (33.3%) in <6 month infants (p <0.001), Only 17.5% of the patients had rotavirus immunization however, the positivity rate among those with rotavirus immunization was only slightly lower (40.0%) as compared to those having incomplete rotavirus immunization (40.4%) (p=0.947). Dehydration rate was significantly higher among cases with incomplete immunization (p <0.001).Conclusions: Severe malnutrition, mix/formula feed and improper hygiene makes the children prone for developing acute rotavirus diarrhea. Children with acute rotavirus diarrhea should be monitored for the development of severe dehydration, decreased urine output and electrolyte derangement especially hypokalemia.

Background: In addition, Health promoting behaviours among the nursing students may affect the quality of patient education. Therefore, this study was undertaken to determine the health-promoting lifestyle behaviours of nursing students in a tertiary care institute, Maharashtra.Methods: This cross-sectional study was performed on 124 nursing students. Health Promotion Lifestyle Profile Proforma (HPLP)was prepared which consists of two parts, Part I deals with the sociodemographic characteristics of the participants and Part II of the proforma deals with Health-promoting lifestyle information which was a modified version of Health Promoting Lifestyle Profile II (HPLP II). It consists of 46 items divided into 7 subscales (Health responsibility, Physical activity, Food practices, Spiritual growth, Self-concept, Inter personal relations and Stress management). Internal consistency (Cronbach’s alpha) of this tool was 0.8197. Permission of Institute Ethical Committee was taken. Descriptive statistics were used to describe HPLP. Data was analyzed by using analysis of variance (ANOVA) and Mann Whitney test. Results: Majority 89(71.77%) were have good HPLP score and 29(23.39%) were excellent category. The mean overall (Total) HPLP score was 62.27±9.66 (range 33-87). The highest mean score in the subscale were for self-concept and spiritual growth. The lowest scores were for food practices and physical activity. Highly significant difference (p<0.0001) was found between overall mean HPLP scores among the different age groups.Conclusions: These nursing students had reasonably good orientations towards health behaviours. Attention need to be paid for healthier food choices. Health promotion planning to motivate students for regular physical activity with the purpose of promoting health and preventing diseases is necessary.
