Assessment of biomass potential for Power Production
Authors: E. Mateos  , J.M. Edeso
Published: April 2017

The aim of this research Project is to develop a methodology to evaluate forest biomass for calculating energy production and resources cartography by means of the use of GIS (Geographic Information System) in the Urdaibai (Biscay). The project tries to determine the potential, available, and usable as energy resource, residual forest biomass, after the treatments of forest species in the area. The first part of the project aims at validating the ground map of the Urdaibai (Spain) obtained in the last Inventario Forestal Nacional (IFN3). In order to complete this part of the project, it is necessary to carry out a study on the ground composition in the area by sampling and subsequent laboratory analysis. In this inventory phase, the use of U.S.L.E/R.U.S.LE (Universal Soil Loss Equation) for calculating soil loss is suggested, since this equation is one of the main tools able to estimate the mean erosive rate of a territory. By means of this empiric model, it will be possible to determine the current soil erosion rate and its potential evolution due to different forest treatments that are characteristic of the most representative forest species in the area.

Published: April 2017

Proton Exchange Membrane (PEM) Fuel Cells are power sources that convert energy of gaseous hydrogen into electric energy. In comparison with usual electrical batteries, PEM Fuel Cells are best suited to applications adaptable to customer demands that involve high power density, stability and prolonged life cycle. From the mathematical point of view, PEM Fuel Cells are a multivariable nonlinear system. Experimental investigation of such as a system considering as many input factors without a proper statistical method could result in hundreds of time-consuming experiments that cannot guarantee an adequate solution. The Design of Experiment provides a very efficient methodology to obtain a mathematical model for the PEM Fuel Cells with only a few experiments. In this paper, the development of a PEM Fuel Cells mathematical model based on the Design of Experiment methodology is described.
Smart City, Sustainable Mobility, Home-Work Mobility:Data Analysis and Actions
Authors: S. Vergura
Published: April 2017

The paper deals with the issue related to the homework mobility of the employees. This issue is very important because many employees have similar working hours, starting at the same hour and finishing at the same hour. The result is a significant increase of traffic congestion and pollution in these hours. Similar situation occurs for students who have to go to school or go home. The previous cases coexist very often and are related each other. The aim of this paper is to present the results of a survey about the home-work mobility of the municipality employees of three medium cities located in the South of Italy. It results that the car is the privileged vehicle for the home-work transfer, independently from the costs of the transfer and from the time needed to reach the nearest stop of public transport vehicle. In a relevant number of cases the car is also the essential vehicle, because of intermediate mandatory stops or to the need to limit the transfer time. In these cases, the use of an electrical car could be an effective solution to join the need to use a car with the need to limit the pollution.

Authors: F. Botticella  , F. De Rossi  , R. Mastrullo  , G.P. Vanoli  , L. Viscito
Published: April 2017

This article presents saturated critical heat flux results in an aluminium heat sink at high saturation temperatures. The test section is made up of seven rectangular mini-channels that are 1.0 mm deep and 2.0 mm wide, with a heated length of 25 mm. R134a has been used as the working fluid. The effect of mass flux G (ranging from 150 up to 330 kg/m2 s) has been investigated. All tests have been performed at medium to high saturation temperatures, ranging from 25 °C up to 70 °C. The experimental results showed that the saturation temperature had only a mild influence on the CHF, at each mass flux imposed. On the contrary, when increasing the mass flux at a given saturation temperature, the critical heat flux was observed to increase significantly. Finally, the prediction capability of a well-known critical heat flux correlation has also been tested.
Phasor Measurement Unit-Based Power Sharing for Optimal Decentralized Controller Design of Inverter-based Microgrid
Authors: M. A. Hassan  , M. A. Abido
Published: April 2017

Nowadays, a powerful controller is essential for cost and reliability concerns for the future smart grid. In this way, the decentralized inverter control is used extensively in the microgrids. Limited system stability is mainly one of the most important issues that face the decentralized inverter control because of the lack of communications among the different distributed generation (DG) inverters. In this paper, the stability enhancement of the droop based decentralized inverter control in the microgrid is investigated. An optimal control strategy based on power sharing is proposed to incorporate the information provided by phasor measurement units (PMU) to improve the microgrid stability. The traditional droop controller has been modified to improve the stability of the microgrid. An optimal controller design based on the desired power sharing of each DG unit and the acquired information of total generation is proposed. The performance of the proposed control strategy is evaluated based on the nonlinear time domain analysis. The results show satisfactory performance with efficient damping characteristics and confirm the effectiveness of the proposed controller.

Published: April 2017

t. In many countries, diverse legislations are today asking for more rational use of energy. For this reason, several initiatives are nowadays promoting a reduction of the overall energy consumption. The European Union has published a Directive 2009/125/EC which fix eco-design requirements to energy-related products. One of these products is power transformers which are a basic piece of generation, transmission, distribution and consumption of electrical energy. The operation of these machines implies the transformation of energy, a part of this energy is dissipated in electrical and magnetic circuits. The amount of losses produce by transformers is defined during the design of these machines. So, they must comply with the above EU Directive. In fact, the Official Journal of the European Union has set a list of energy efficiency limits to be fulfilled by new machines sold in Europe (Commission Regulation 548/2014). This article presents three parts. The calculation of the maximum performance is presented in the first part. This is independent of the load percentage, the impedance and the voltage level. A description of the European fleet of power transformer, up to 100MVA is presented on the second section. In the last part of this work, the efficiency of the fleet is analysed using the maximum performance concept and considering the EU Regulation.
Day-ahead Optimal Scheduling of Loads and Dispatchable Resources in a Hybrid AC/DC Microgrid of an Industrial System
Authors: L. Alfieri  , G. Carpinelli  , D. Proto  , G. Russo
Published: April 2017

Industrial systems are usually characterized by high energy consumption and presence of sensitive loads which require high levels of Power Quality. Based on the grid architecture of an actual Italian industrial facility, this paper proposes the installation of a hybrid AC/DC microgrid. The hybrid microgrid includes dispatchable and non-dispatchable renewable generation units, battery storage systems and controllable loads. An optimization model is formulated to solve the problem of the day-ahead optimal scheduling of the microgrid. The model aims to optimize the operation of dispatchable resources, controllable loads and storage systems minimizing the daily costs of the energy imported from the AC grid and the costs required by the dispatchable generators while satisfying operational constraints such as those related to the production process of the industry facility. Different case studies are investigated in order to show the feasibility and effectiveness of the proposed procedure.

The grid integration of renewable energy, and particularly in Spain, supposes an important problem to deal with for Distributor System Operators (DSO). Most of the times Wind Energy Farms are located in places that are far away from the transmission networks so they have to be integrated into distribution networks that are frequently next to their static rate. Current regulations make almost impossible to build new overhead lines so the increase of the capacity of the existing lines is a new target for the DSO. One of the developed options to solve this issue is the dynamic management of the network. This paper is devoted to the analysis of a real case of ampacity management in a 132 kV overhead line placed in a high-wind generation area. The obtained results show that this approach can increase the lines capacity in a significant percentage.

Published: April 2017

This paper describes a preliminary experience with the installation and use of a no-gap power quality meter network along a distribution grid in the North of Spain. No-gap power quality meters record all cycles of voltage and current waveform for all the monitored channels. This approach extends the analysis further than the classical approach provided by other power quality meters that records only survey data and events triggered according predefined rules. A comparison with the classical approach is discussed and the results of a two year power quality survey are also provided.
Energy audit as an input for energy management and energy efficiency improvement in a gypsum manufacturing plant
Authors: H. Bernardo  , F. Oliveira  , L. Serrano
Published: April 2017

. This paper aims at presenting the main results of an energy audit performed to a gypsum production plant, in Portugal, which due to the amount of energy consumed must comply with the Portuguese program SGCIE (Intensive Energy Consumption Management System). The program was created in 2008 to promote energy efficiency and energy consumption monitoring in intensive energy consuming facilities (energy consumption higher than 500 toe per year). Facilities operators are required to perform energy audits and take actions to draw up an action plan for energy efficiency, establishing targets for energy consumption reduction and greenhouse gases emissions indexes. An energy audit was carried out to identify potential energy conservation measures for improving energy efficiency, and also typical energy consumption patterns, sector/equipment load profiles and thermal equipment performance. This tool gives managers the information to support decision making on improving energy performance and reducing greenhouse gas emissions. A number of tangible targets and measures were devised and set to be implemented in the next few years. Results show that there is a considerable potential for reduction in the energy consumption and greenhouse gases emissions of gypsum manufacturing plants. Here, as elsewhere in the industrial sector, energy efficiency can only be achieved through a continuous energy monitoring and management system.
Investigation and Understanding the Conditions of Power Transformer Internal Faults using On-line Technique
Authors: E. A. F. Aburaghiega  , M. E. Farrag  , D. M. Hepburn
Published: April 2017

Loss of a power transformer in a utility, generation plant or process can cost many millions of pounds, depending on how long it is out-of-service. Internal faults are said to be the most likely cause of disruption in transformer performance and interruption of power supply. Improving understanding of the relationship between types of problem in transformers and their indicators will help to identify internal faults and their locations. Developing an on-line method to monitor and investigate the health conditions of the transformer will help asset managers assess plant while it is operational, leading to reduced running costs and increased life. The proposed method is based on measuring electrical parameters at both sides of a transformer to differentiate between healthy and faulty conditions while it is still in service. In this study, two windings of five sections each have been simulated. The values for each section’s resistance and impedance are calculated based on copper windings, interleaved construction and insulation between sections. The simulated power transformer is connected to an inductive load. Comparison of simulated input and output voltages and currents has been conducted to identify indicators of the transformer’s health status. Developed faults at different locations in the transformer windings are used to study the transformer performance and to recognise the fault indicators. The simulation results show very clearly that there are trends in the measured parameters that are attributed to the type of fault within the transformer. Hence a simple logic comparator can be easily deployed to identify the fault location in relation to the transformer health status.

The local power generation facilities were interconnected into national, regional, continental and nowadays intercontinental networks. A lot of problems and tasks occur, like the controllability, the integration of the renewable sources, decrease of the spread over of the outages. The present answers for the challenges are mainly extensive, the networks are enlarged, the traditional polluting generation capacities, the power plants, storages are developed and extended. Beside the “Electrical globalisation” occur local civil initiatives, the higher integration level of the grid resulted the need for new structures, as microgrids and locally controllable Smart Grids. Our aim to develop structural and operational solutions for decrease the problems mentioned above, make the supply sustainable. Beside the centralized intercontinental networks occur the microgrid, smart grid and “power quality island” solutions. Our basic concept is to develop a new virtual smart network cell haven’t applied yet. It forms virtual microgrid island, uses the existing network, connected on IP base, aggregates small generators and consumers Through this solution the load will be balanced, the dynamic of the operation will be decreased, the load-generation balance will be realized on local level, we move toward the sustainable power supply.

Authors: Hovdestad W. , Shields M. , Williams G. , Tonmyr L.
Published: May 2017

Introduction

Young mothers’ families are at increased risk of child maltreatment and
other poor health and social outcomes.

Methods

Young mothers’ families are at increased risk of child maltreatment and
other poor health and social outcomes.

Results

Twenty-six percent of young mothers were 18 years or younger. Most (68% of
teen-mother families and 57% of families with a young adult mother) received social
assistance as their main source of income compared with 36% of families with a mother
aged 22 years or older. Teen and young adult mothers were more likely than those aged
22 or older to have childhood histories of out-of-home care (31% and 23% vs. 10%) and
were more likely to have risk factors such as alcohol abuse (25% and 23% vs. 18%) and
few social supports (46% and 41% vs. 37%). Secondary caregivers in families with
young mothers also had more risk factors. Teen and young adult mother families were
more likely to have their child placed out-of-home during the investigation (29% and
27% vs. 17%). All were equally likely to be victims of domestic violence and to have
mental health issues.

Conclusion

Within this sample of high-risk families, young mothers’ families were more
at risk than comparison families. Mothers’ youth may be a useful criterion to identify
families for targeted interventions.
Study on the Reactivity of Amino Acid Chemosensor, NPFNP, with Ethanol: Structural Elucidation through Single Crystal XRD and DFT Calculations
Authors: Varghese Beena , Al-Busafi Saleh N. , Suliman Fakhr Eldin O. , Al-Kindy Salma
Published: May 2017

A novel ethoxy derivative of an amino acid chemosensor, 3-naphthyl-1-phenyl-5-(2ʹ-fluoro-5ʹ-nitrophenyl)-2-pyrazoline (NPFNP), has been synthesized and characterized by different spectroscopic methods.  A single crystal of the ethoxy derivative, 3-naphthyl-1-phenyl-5-(2ʹ-ethoxy-5ʹ-nitrophenyl)-2-pyrazoline NPENP, has been obtained and characterized.  The structure holds interest as it carries biologically active pyrazoline as a central ring attaching to electron donating and withdrawing substituents. The major motivation for this work was to gain detailed insight into the structural parameters of this compound for investigating the influence of crystal packing and geometrical dimensions on optical properties. Time-dependent DFT calculations have been employed for comparing the XRD data with theoretical parameters. The results show that the DFT method at B3LYP/6-31G level can well reproduce the structure of the title compound.

Aloglossia e Diacronia: motivações para erros por substituição no Libro dell'Abate Isaac di Siria
Authors: Vilaça Cynthia Elias de Leles
Published: April 2017

Neste artigo, apresenta-se uma análise dos padrões de erro por substituição encontrados na transmissão do tratado ascético medieval Libro dell’Abate Isaac di Siria, a partir da edição crítica desse texto, preparada por Vilaça (2012). Considerando que os testemunhos utilizados no processo de estabelecimento do texto crítico não são todos da mesma época e provêm de localidades diferentes da Itália, o principal intuito deste trabalho foi o de especular possíveis relações entre erros por substituição e casos de aloglossia ou de diacronia. Para isso, selecionaram-se apenas as substituições em nível morfológico e as por sinonímia, as quais tendem ser voluntárias e podem revelar influências do dialeto do responsável pela reprodução do texto ou de seu estado de língua.
Regularidades em mudança semântica: um estudo de caso no domínio da junção
Authors: Longhin Sanderléia Roberta
Published: April 2017

O objetivo deste trabalho é analisar aspectos de regularidade em mudança semântica a partir da descrição, em perspectiva longitudinal, de duas trajetórias de mudança semântico-pragmática percorridas pelo juntor enquanto, que levaram à expressão de significados com grau mais elevado de subjetividade: contraste, que decorre da percepção de uma diferença, incompatibilidade ou conflito entre entidades comparáveis em alguma dimensão; e condição, que decorre da criação de cenários hipotéticos, fundados ou não na realidade. Fundamentando-me teoricamente em um modelo que confere à pragmática um papel fundamental na mudança semântica (TRAUGOTT; DASHER, 2002) e considerando como corpus textos de gêneros diversos representativos dos séculos XIII ao XXI, focalizo sobretudo o peso dos significados fonte, a natureza dos contextos que favorecem a emergência de polissemias e o estatuto dos significados novos.

Para este texto, foram escolhidas 5 das cartas analisadas para exemplificar o alcance do trabalho que está sendo realizado em projeto mais amplo, que visa ao conhecimento aprofundado do contexto de produção e circulação de manuscritos no Brasil colonial e a sua contribuição para os estudos sobre a História da Língua Portuguesa.
Documentos Baianos: Autos de curandeirismo sob a lente filológica
Authors: Queiroz Rita de Cássia Ribeiro de
Published: April 2017

A edição de textos é uma das atividades mais nobres da Filologia, sendo exercida desde a Antiguidade Clássica, na Grécia. A tarefa de editar está atrelada ao labor praticado pelo ser humano em salvar do esquecimento seus feitos, deixando-os registrados nos mais variados suportes: pedra, argila, papiro, pergaminho, papel e, mais recentemente, nos meios virtuais. Deste modo, os filólogos empreenderam a tarefa de salvaguardar das marcas do tempo os textos, sejam estes literários ou não. Na Bahia, precisamente na Universidade Estadual de Feira de Santana, há o Centro de Documentação e Pesquisa - CEDOC, cujo acervo conta com processos cível e crime dos séculos XIX e XX. Neste acervo, encontramos um processo crime sobre a prática de curandeirismo, o qual vem sendo editado semidiplomaticamente. Para a realização desta edição, procedemos à sua descrição, na qual informamos todos os aspectos extrínsecos, tais como número de fólios, tipo de papel, presença de manchas ou outros danos sofridos pelo suporte, número de linhas, presença de carimbos e/ou sinais especiais, etc.; para a transcrição, trazemos os aspectos intrínsecos, ou seja, a existência de abreviaturas, palavras unidas e/ou separadas, tipo de letra, etc. A opção pela edição semidiplomática se justifica pelo fato de oferecermos, desta forma, um retrato fiel do documento, pois nesse tipo de edição a intervenção do editor é mediana, assim quaisquer pesquisadores terão acesso ao documento sem a necessidade de manuseá-lo, o que evita o seu desgaste físico. Diante do exposto, apresentamos neste artigo a edição semidiplomática do auto de curandeirismo que tem como réus Victorio Araujo da Silva e Pedro Alves d’Almeida. O documento conta com 36 fólios, escritos no recto e no verso.

A expografia de Lina Bo Bardi como mesa de montagem
Authors: Pugliese Vera
Published: April 2017

O artigo investiga a relação entre a fisiologia e a eficácia da expografia da pinacoteca do Museu de Arte de São Paulo – MASP [1968], confrontando a montagem da exposição com outros discursos com os quais o projeto expográfico dialoga. Sua hipótese é que a concepção do projeto de Lina Bo Bardi constitua um ponto de inflexão de diferentes noções de genealogia e historicidade, entre os pensamentos historiográfico-artístico e expográfico. Para tal, o texto discute a possibilidade de compreender este projeto como mesa de montagem, segundo a acepção de Georges Didi-Huberman e quais seriam possíveis desdobramentos e implicações desta associação.

The biggest contribution to globalisation has been to redefine its practices in the light of a world of transnational connections and communications, which to a certain extend imply the end of the nation state and of the provincialism (parochialism) implicit in national culture. In this essay we would like to confront, on the one hand, the case of the journal Third Text in relation to Art in America in order to the dismantling of the Western paradigm based on a hegemonic and centralised notion of art occurred in the area of post-colonial thinking, which was slowly replacing the “old” and “Eurocentric” internationalism of the art world with a wider notion of a “globalist” imaginary in contemporary art.
A voz do silêncio na arte de Edward Hopper
Authors: Flores Maria Bernardete Ramos
Published: April 2017

Edward Hopper criou formas onde reinam o vazio e o silêncio para expressar ícones da topologia da vida moderna norte-americana (hotel, cafeteria, bar, vagão de trem, estrada, teatro, cinema, salas de espera). São imagens reconhecíveis, porém cheias de fantasmas. As paisagens rurais evocam a nostalgia pela “idade de ouro”; as paisagens urbanas são melancólicas e iluminadas por uma luz estranha. Incluído entre os descontentes da modernidade, sua arte encontra-se sob o signo do Spiritus phantasmaticus, que ilumina artistas, poetas e pensadores de temperamento saturnino, inclinados a esquecer das horas e dos dias, postos a refletir sobre o mistério da realidade cotidiana.
Arte, política e geopolítica nos anos 1960
Authors: Jaremtchuk Dária
Published: April 2017

A partir das décadas de 1960 e 1970, Nova York se transformou em rota para os artistas brasileiros. A opção da viagem se afirmou não apenas pela importância do lugar em relação às artes, mas por ações deliberadas levadas adiante por instituições norte-americanas, aqui denominadas de “políticas de atração”. Isso significa que foram desenhadas estratégias específicas de aproximação e de atuação na América Latina para, acreditava-se, impedir a repetição da experiência comunista de Cuba. Nesse sentido, o artigo discute como os espaços de arte e de cultura passaram a funcionar mais diretamente como ambientes de recepção indispensáveis nas atividades políticas, diplomáticas e comerciais e de como, no Brasil, os Estados Unidos se apresentaram como o modelo civilizatório e guarida dos valores democráticos e universais, sendo as artes são uma peça compositiva fundamental na construção dessa representação.
Museus nas Américas
Authors: Magalhães Roberto Carvalho de
Published: April 2017

A ideia de museu - e, em particular, de percurso narrativo dentro dos museus – que temos hoje é, fundamentalmente, a que recebemos do século XIX. Enquanto instituição oficializada social e burocraticamente, o museu tem uma história curta, de pouco mais de dois séculos. Mas a gestação dessa ideia tem início em tempos muito mais remotos e foi consideravelmente longa: um processo gradativo de acúmulo de patrimônio e de predisposição de itinerários ou narrativas dentro de certas estruturas culturais e/ou religiosas, que são uma das heranças do museu moderno. Uma herança de caráter quase devocional, mas também – e sobretudo – formal. Num determinado momento da história, surgem uma forma arquitetônica e uma estrutura narrativa que se impõem como forma de apresentar arte. Conhecer esse processo é importante, pois nos permite entender muitos mecanismos subjacentes à forma e às atividades dos museus ainda hoje.
Os arquivos da arte na pathosformeln das redes e nas ruínas do coletivo
Authors: Farina Mauricius Martins
Published: April 2017

As imagens que são materializadas pela experiência da arte, como um lugar de vivências adquiridas e compartilhadas, apresentam uma diversidade de processos pondo-se a demonstrar que sua cronotopia se expressa na suspensão de um tempo linear. A noção de pathosformeln ou 'fórmula das emoções', que Carlo Ginzburg e George Didi-Huberman recuperam de Aby Warburg está carregada de indícios de uma lembrança que se ativa pela emoção, pelo drama e, nesse campo, as imagens são fundamentais. Assim, pretenderemos refletir neste texto, com ajuda das imagens, sobre as relações entre a memória a partir de seus arquivos físicos, tendo em conta o imaginário, trabalhando na da instabilidade de um tempo em ruínas, quando o terror se apresenta numa versão mediática ameaçando aos próprios arquivos da cultura-mundo.

Published: April 2017

Trata-se da reflexão sobre o modo como os espaços de exposição se relacionam com os assentos (especialmente as cadeiras), e vice-versa, sejam como objetos de exibição (arte, design, decoração), sejam como locais de descanso, de vigilância e especialmente como orientadores de certos pontos de vista para olhar obras de arte.  A partir de um passeio acidental por vários museus e por obras com cadeiras, frente a elas ou nelas sentados, desejamos pensar em como, ao usá-las, estabelecemos lugares para olharmos, sermos olhados e nos posicionarmos frente à escrita da história e da crítica da arte.
O que é um objeto de museu sem as narrativas que o cercam? Museu do Folclore
Authors: Silva Mariana Estellita Lins
Published: April 2017

Buscamos dialogar com a exposição de longa duração do Museu de Folclore Edison Carneiro, localizado no Rio de Janeiro, que se constitui como uma das vertentes de trabalho do Centro Nacional de Folclore e Cultura Popular. Através desta escolha, pretendemos refletir sobre as narrativas construídas a partir dos objetos museológicos além de problematizar categorias como 'arte contemporânea' e 'arte popular' que definem não apenas o conjunto de objetos sobre o qual nos referimos, mas principalmente sobre o nosso lugar de produção discursiva.

Atopic dermatitis is a skin disease characterized by allergic skin inflammation, redness and itching. The animal model is necessary to find out new drugs. The DNCB-induced animal model of atopic dermatitis includes the following steps: 1) Selection of animals; 2) Shaving of dorsal skin; 3) Applying DNCB once in 24 hours for three days; 4) Monitoring the development of atopy on day 4 post DNCB application. Further, the efficacy of reference drug can be determined by applying on the atopy skin, depends on the nature and aim of the work.Video Clip of Methodology: 8 min   Full Screen   Alternate

Background : Nephrotic syndrome (NS) is one of the most common renal diseases in children. The cause of idiopathic nephrotic syndrome is still unknown. Once the prevalence of minimal change nephritic syndrome occupied the three forth portion of the total renal pathology and most of them were steroid sensitive. But list of steroid insensitive nephritic syndrome become more longer today. Therefore renal biopsy is essential for histopathological diagnosis which guides the most accurate way for the treatment of such diseases.Objective : The objective of this study was to find out the pattern of renal histopathology of selected cases of Idiopathic nephritic syndrome.Materials and Method : This prospective study was conducted from January 2004 to December 2015 among children who were suffering from nephrotic syndrome admitted in Paediatric nephrology department, National Institute of Kidney Diseases and Urology(NIKDU), Dhaka. Renal biopsy were done who fulfil the inclusion criteria. Obtaining ultrasound-guided percutaneous renal biopsy specimens by means of an automated biopsy gun, were evaluated histopathologically under light and direct immunoflurescent(DIF) microscopy by an experienced histopathologist.Results : Total admitted childhood nephrotic syndrome during this period was 1512 and renal biopsy was done in 354 patient. Among the 354 children, histopathological findings were mesangial proliferative glomerulonephritis [MesPGN]was 92(25.98%),minimal change disease[MCD]was79 (22.32%), IgM nephropathy[IgMN]was69(19.49%), focal segmental glomerulosclerosis[FSGS] was 37(10.45%), membranoproliferative glomerulonephritis [MPGN] was 37(10.45%), IgA nephropathy [IgAN] was 20(5.65%),membranous nephropathy[MN] was 08(2.27%) and others were 12(3.39%).Conclusion : In this study we found that theselected patient for renal biopsy in the last 12 years showed that minimal change disease had been decreasing but the other histological types are increasing gradually such as mesangial proliferative glomerulonephritis, FSGS and IgM nephropathy.Northern International Medical College Journal Vol.8(1) July 2016: 165-169

Background : The Thalassaemia is an inherited haemoglobulin disorder causes hemolytic anemia which usually requires life-long blood transfusion therapy. Therefore transfusion dependent thalassaemia major patients suffer from the effect of deposition of excess iron in the liver, heart and endocrine glands.Objective : The aim of present study was to find out the association of serum ferritin and SGPT in transfusion dependent thalassaemia major patient.Methodology : This cross sectional study was carried out in Day care unit (DCU) of Transfusion Medicine department, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, during January 2014 to December 2014. Total of 110 clinically diagnosed Thalassaemia major (TM) between (5-35 years) cases of either sex from the above mentioned department attending the DCU were selected purposively for this study. Data were collected on clinical examination findings, laboratory investigations, ABO and Rh Blood Group, Serum ferritin and SGPT (Serum glutamic pyruvic transaminase) after taking informed consent.Results : The following observations and results were obtained in this study. The mean age was found 17.15±8.77 years with range from 5 to 35 years and male to female ratio was 1.2:1 (male 59 and female 51). Sixty eight (68.0%) patients came from rural area, 43.6% patients were student, 77.3% patients had completed primary education, 57.3% of the patients came from middle class family and 72.7% patients were unmarried. About 46.4% of the patients had moderate anaemia, 28.2% had jaundice, 79.1% had hepatomegaly, 82.7% had splenomegaly and 30.9% had complication due to iron overload. Mean haemoglobulin (Hb%) was found 6.65±1.63 gm/dl, mean serum ferritin was found 3785±17637 ?g/L and mean SGPT was found 134.8±77.94 U/L. There was a significant positive correlation (r=0.259; p=0.006) between serum ferritin and SGPT.Conclusion : Considering the study result it can be concluded that there is a positive significant correlation between serum ferritin with SGPT level.Northern International Medical College Journal Vol.8(1) July 2016: 170-173

Background : Premature infants frequently suffer from feeding intolerance and is highly associated to morbidity and mortality. It is a great challenge which have to face all the neonatologist. Feeding intolerance can be defined by difficulty in ingestion or digestion of the milk that causes a disruption in the enteral feeding plan due to the manifestation of some clinical symptoms. These symptoms include gastric residuals, emesis, abdominal distention, visible bowel loops, and change in the character of stool etc.Objective : To determine the frequency of feeding intolerance in hospitalized preterm neonates.Methods : This prospective study was carried out on preterm neonates admitted at neonatal intensive care unit of Padma General Hospital from 1st January 2016 to 31st December 2016. Inclusion criteria included Preterm infants of both genders from day 0 to day 28 of life and with gestational age (GA) of 28 to 36 weeks (estimated by 1st day of maternal last menstrual period). Diagnosis of feeding intolerance depends on presence of one or more signs that leading to interruption of the enteral feeding regime of the preterm.Results : The incidence of feeding intolerance in hospitalized preterm was 4.2%Conclusion : The percentage of feeding intolerance in our study is 4.2% of the preterm neonate.Northern International Medical College Journal Vol.8(1) July 2016: 178-180
