Entre dois modelos medievais de justiça: as narrativas das crônicas ibéricas (séculos XIII-XIV)
Authors: Barros José D'Assunção
Published: January 2016

Este artigo busca discutir aspectos relacionados às formas de mediação que regiam o Direito Medieval Ibérico, através da figura do Rei, tal como este tipo de mediação aparecia nas narrativas contidas nas crônicas e genealogias da época. As relações entre História, Justiça e Poder são discutidas no âmbito de um discurso narrativo específico e através de metodologias direcionadas para a análise estrutural. As fontes narrativas estudadas são os chamados Livros de Linhagens, que eram genealogias da nobreza medieval ibérica da épocahttp://dx.doi.org/10.15304/dereito.24.2.2581
La perspectiva de las familias de un centro educativo digital con modelo 1 a 1: implantación del Proyecto E-DIXGAL como desarrollo del Plan Escuela 2.0 y el Proyecto Abalar en Galicia
Authors: Fraga Varela Fernando , Duarte Fernández Alba
Published: January 2016

El presente trabajo aborda el estudio de la visión que las familias tienen del modelo 1 a 1 en un centro educativo con una propuesta de digitalización total de Galicia. Con este objetivo se diseñó un cuestionario específico dirigido a las familias del alumnado del quinto curso de primaria de un centro educativo inmerso en el proyecto experimental denominado E-DIXGAL. Este proyecto se inicia en el curso 2014-15 y utiliza el modelo 1 a 1 para dar soporte al proceso de enseñanza y aprendizaje. Los resultados muestran en general una buena acogida y valoración. Sin embargo llama la atención que no todas las familias tienen una misma perspectiva, mostrándose un porcentaje muy crítico con la propuesta. También se aprecia continuidad con los procesos de aprendizaje que ya se venían trabajando con los libros de texto. Finalmente se identifican una serie de aspectos susceptibles de mejora que pueden ser tomados como referencia desde el propio centro para enriquecer la iniciativa en relación con las familias: destacamos el conocimiento del propio proyecto y sus características así como la infraestructura que se ha desarrollado para el trabajo con los materiales digitales.DOI: http://dx.doi.org/10.15304/ie.25.2826

Chirurginis endometriozės gydymas: literatūros apžvalga
Authors: Simavičius Andrius , Bogužienė Emilija , Kupčiūnaitė Rasa , Černauskis Karolis
Published: January 2016

Endometriozė – dažna reprodukcinio amžiaus moterų liga, sukelianti skausmą ir nevaisingumą. Chirurginis gydymas yra vienas iš svarbiausių endometriozės gydymo etapų. Tinkamas chirurginis gydymas palengvina endometriozės sukeliamus simptomus ir padidina pastojimo dažnį gydant nevaisingumą. Laparoskopinės chirurgijos technikų ir taktikų tobulėjimas lėmė, kad endometriozės chirurginis gydymas tapo svarbiu gydymo etapu, turinčiu pranašumų, palyginti su medikamentiniu gydymu. Skiriamos trys pagrindinės ligos formos: pilvaplėvės, kiaušidžių ir gilioji rektovaginalinės pertvaros endometriozė. Paprasčiausia atlikti paviršinių endometriozės židinių abliaciją, o gydant giliąsias ligos formas židinių ekscizijos būdu reikalinga chirurgo patirtis ir įgūdžiai. Endometriozės chirurginis gydymas yra tausojantis arba radikalus, jei šalinama gimda ir (ar) kiaušidės. Labai svarbu laparoskopijos būdu nustačius endometriozę pašalinti visus matomus pažeidimus. Pagrindinis šio straipsnio tikslas yra padėti suprasti chirurginio gydymo svarbą gydant endometriozę ir pateikti moksliškai pagrįstus įrodymus, kaip tinkamai gydyti endometriozę chirurginiu būdu.

Published: January 2016

ĮžangaIzoliuotas trauminis skrandžio plyšimas pasitaiko labai retai. Apie 95 % atvejų diagnozuojami gretutinių organų sužalojimai. Dėl santykinai palankios skrandžio anatomijos, jo mobilumo bei storos sienos skrandžio plyšimai sudaro 0,02–1,7 % visų bukų pilvo sužalojimų. Mūsų tikslas – aprašyti neįprastą trauminį skrandžio plyšimą, gydytą minimaliai invazinės chirurgijosmetodais.Atvejis62 metų vyras skubos tvarka hospitalizuotas į chirurgijos skyrių dėl skausmo epigastriumo srityje ir kraujavimo iš viršutinės virškinimo trakto dalies klinikinių požymių. Ligonis teigė, kad prieš 2 savaites patyrė buką pilvo traumą. Iš anamnezės žinoma apie skrandžio opaligę. Atlikus endoskopinį tyrimą rastas visą mažąją kreivę apimantis skrandžio išopėjimas be aktyvaus kraujavimo požymių. Pilvo organų echoskopijos duomenimis, konstatuota bursa omentalis skysčio sankaupa, priekinės pilvo sienos hematoma ir laisvas skystis pilvo ertmėje (apie 500–700 ml). Įtarta pridengta skrandžio kūno mažosios kreivės perforacija ir hemoperitoneumas. Ligoniui siūlytas skubus operacinis gydymas, bet jis tokio gydymo kategoriškai atsisakė. Konservatyvaus gydymo metu, atsiradus infekcijos požymių, atliktas pilvo organų ultragarsinis ir kompiuterinės tomografijos tyrimai, kuriais nustatyta bursa omentalis skysčio sankaupos ir priekinės pilvo sienos hematomos supūliavimas. Atliktas ultragarsu kontroliuojamas pilvo sienos hematomos dravimas 12 Fr drenu. Endoskopinės procedūros metu per užpakalinę skrandžio sieną drenuotas bursa omentalis pūlinys, į jo ertmę įkišus du 7 Fr drenus. Normalizavosi temperatūra, kraujo tyrimų rodikliai, pacientas pradėjo normaliai valgyti. Geros būklės išrašytas į namus 35 parą nuo hospitalizacijos pradžios. Stebėtas ambulatoriškai. Komplikacijų nekonstatuota. Po 2 mėnesių endoskopiškai pašalinti skrandžio drenai.IšvadaSkrandžio trauminio sužalojimo sepsinės komplikacijos gali būti efektyviai gydomos minimaliai invazinės chirurgijos priemonėmis – perkutaniniu ir endoskopiniu transgastriniu pūlinių drenavimu.

Authors: Pankratjevaitė Lina , Samiatina-Morkūnienė Diana
Published: January 2016

ĮvadasViena iš retų elektrokardiostimuliatoriaus ar defibriliatoriaus implantacijos komplikacijų yra širdies perforacija. Jos klinikinės išraiškos pasižymi didele įvairove ir gali sukelti daug diagnostikos sunkumų.Klinikinis atvejisĮ mūsų ligoninę dėl sinusinio mazgo silpnumo sindromo hospitalizuotas 80 metų ligonis. Jam implantuotas dviejų kamerų ilgalaikis kardiostimuliatorius. Procedūros komplikacijos – širdies perforacija, hemoperikardiumas ir dešinės pusės hemoto­raksas. Po procedūros praėjus kelioms valandoms, ligonis pasijuto blogai, tačiau tiksli širdies perforacijos diagnozė nustatyta tik penktą dieną po kardiostimuliatoriaus implantavimo, kai atlikta krūtinės ląstos kompiuterinė tomografija. Tuomet elek­trofiziologas, padedamas chirurgų, kontroliuojant procedūrą torakoskopu, pašalino migravusį elektrokardiostimuliatoriaus elektrodą. Kitą dieną ligoniui įdėtas naujas elektrodas. Praėjus šešiolikai dienų po elektrokardiostimuliatoriaus implantavimo, vyras išrašytas iš ligoninės.Išvados Literatūroje minima, kad dauguma migravusių elektrodų gali būti paprastai ištraukti kontroliuojant procedūrą rentgenu ar stebint echokardiografu operacinėje, kartu esant pasirengusiai chirurgų komandai. Mes sėkmingai pašalinome elektrodą kontroliuodami procedūrą torakoskopu.
Krūtinės angos sindromas
Authors: Jasinskas Mindaugas , Minderis Mindaugas
Published: January 2016

Krūtinės angos sindromas (KAS) (angl. thoracic outlet syndrome, TOS) – tai visuma simptomų, kuriuos sukelia petinio nervų rezginio, poraktinės arterijos ir (ar) venos suspaudimas pereinant iš kaklo ir krūtinės į viršutinę galūnę. Nors yra gana paplitęs, palyginti su kitomis periferinėmis viršutinės galūnės neuropatijomis (vidurinio ar alkūninio nervo), krūtinės angos sindromas yra dažnai nediagnozuojamas. Patologiją sukelia kaklo trauma, anatominės fibromuskulinių struktūrų anomalijos krūtinės angos srityje, fizinio krūvio nulemti minkštųjų audinių pokyčiai. Dėl anatomijos ypatumų ši kompresija pasireiškia itin įvairiai. Pagal vyraujančius simptomus išskiriami trys krūtinės angos sindromo tipai: neurogeninis, arterinis ir veninis. Izoliuota kraujagyslių kompresija pasitaiko retai – apie 5 % atvejų. Pagrindiniai diskusijų objektai – diagnostika ir gydymas. Ieškoma patikimo ir objektyvaus diagnostinio metodo, kuriuo remiantis būtų galima nesudėtingai atskirti nuo panašia simptomatika pasireiškiančių patologinių būklių. Daugeliu atvejų patologijos neįmanoma nustatyti vaizdiniais ar išmatuoti elektrofiziologiniais tyrimais, taigi kai kurie specialistai nenori pripažinti jos egzistavimo. Dėl gydymo strategijos – taip pat daug prieštaravimų. Nors dažniausiai literatūros šaltiniuose rekomenduojamas chirurginis metodas yra pirmojo šonkaulio rezekcija, kitos techniškai paprastesnės intervencijos taip pat veiksmingos.Šioje apžvalgoje apibendrinami literatūros duomenys, kurie papildomi gausia (šių operacijų skaičius 2015 metais pasiekė beveik 600) asmenine patirtimi. Atkreipiamas dėmesys į klinikinius ypatumus, kurių neakcentuoja ar išvis nemini užsienio autoriai. Pateikiama krūtinės angos sindromo termino atsiradimo istorija, reikšmingi anatomijos ypatumai, aptariama etiopatogenezė, klinikinė išraiška bei dažniausiai praktikoje naudojami diagnostikos ir gydymo metodai.
Whole-Genome Screening of Newborns? The Constitutional Boundaries of State Newborn Screening Programs
Authors: King Jaime S. , Smith Monica E.
Published: January 2016

State newborn screening (NBS) programs routinely screen nearly all of the 4 million newborns in the United States each year for ∼30 primary conditions and a number of secondary conditions. NBS could be on the cusp of an unprecedented expansion as a result of advances in whole-genome sequencing (WGS). As WGS becomes cheaper and easier and as our knowledge and understanding of human genetics expand, the question of whether WGS has a role to play in state NBS programs becomes increasingly relevant and complex. As geneticists and state public health officials begin to contemplate the technical and procedural details of whether WGS could benefit existing NBS programs, this is an opportune time to revisit the legal framework of state NBS programs. In this article, we examine the constitutional underpinnings of state-mandated NBS and explore the range of current state statutes and regulations that govern the programs. We consider the legal refinements that will be needed to keep state NBS programs within constitutional bounds, focusing on 2 areas of concern: consent procedures and the criteria used to select new conditions for NBS panels. We conclude by providing options for states to consider when contemplating the use of WGS for NBS.
Potential Psychosocial Risks of Sequencing Newborns
Authors: Frankel Leslie Ann , Pereira Stacey , McGuire Amy L.
Published: January 2016

Various stakeholders have issued recommendations regarding the use of genomics in pediatrics. These guidelines are driven in part by concerns about psychosocial risks of disclosing predictive genomic information during childhood. As genomic sequencing becomes more commonly used in pediatric settings, it is important to systematically study the psychosocial impact of genomic sequencing of newborns, including the impact on family dynamics. Through review of the psychological and genetic counseling literature, we identify the following 3 domains of family dynamics that have potential to be impacted by the return of genomic results during the newborn period: perceived child vulnerability, parent-child bonding, and self and partner blame. In this article, we outline the complexity of studying these psychosocial outcomes and our plan to examine them in the BabySeq Project, a randomized controlled trial in both healthy and sick infants, in which the return of genomic information will be compared with standard of care.

Mundos equivocados: cuando la “abundancia” y la “carencia” se encuentran en la Amazonía colombiana
Authors: Verschoor Gerard , Torres Camilo
Published: January 2016

Este artículo describe y analiza los efectos de la minería artesanal que involucra a comunidades Andoque del Resguardo Aduche (Amazonía colombiana) en su seguridad alimentaria. En términos analíticos, el punto de partida es la existencia de diferentes perspectivas sobre las actividades de las poblaciones indígenas. Algunas de estas –las que se basan en la noción de “carencia”– distorsionan los ensamblajes en los que participan las comunidades indígenas, involucrándolas en una disyuntiva que choca contra su concepto de “abundancia”. Lo paradójico de este caso es que en un mundo de “abundancia amazónica” se inserta un modelo deficitario basado en la extracción del oro, en donde se integran elementos exógenos que dificultan el reensamblaje inicial. Desde una perspectiva alejada de la unicidad cultural, esta investigación aborda la multiplicidad de las prácticas y realidades donde los diversos actores enfrentan dilemas de uso de los recursos comunes, se integran al “fácil” acceso al dinero y en la que se desfigura la cosmovisión local que requiere que “no se debe tocar lo que no ilumina el sol”.

India’s Tipaimukh Dam and Bangladesh’s Policy Response: An Analysis
Authors: Toufique Mohammad Mokammel Karim
Published: January 2016

India has undertaken the Tipaimukh project on the Barak River. This river is very important for the north-eastern region of the country. Once built, this project will have various adverse impacts on Bangladesh. Though India has repeatedly said that she will not do anything that is damaging for Bangladesh, the project has only been deferred temporarily. This paper analyzes all the policy alternatives that Bangladesh has at her disposal and argues that the only feasible option that the country has is to ask India for the closure of the project.

Published: January 2016

This article aims to survey the relation of social capital of employees and their organizational silence in governmental organizations of Marivan in 1994. The statistics society of the research was consisted of all employees in governmental organizations of Marivan (600), that 377 persons was determined as statistics sample. The method of the research was descriptive with from the correlation style. The information (data) collector tool was two questionnaires of Nahapieta & Ghoshal (1998) and the Organizational Silence questionnaire of Pinder and Harlos model (2001). The validity of questionnaire was orderly measured 0/86 and 0/83. The gathered data was measured and analysed by using the statistic tests after Regression analysis. The results of Regression analysis illustrate that two dimensions of social capital are purely specifying (explaining) 58 percent of Organizational Silence variance, and the variable of organizational structure of employees is being studied with the most effective and determinative factor on Organizational Silence in society, this factor is reversely explaining the 63 percent of dependent variable changes; and the variable of relational capital of employees is the second effective factor on Organizational Silence in society which is being studied, this factor also explaining 19 percent of dependent variable changes.
Preventing bacterial adhesion on scaffolds for bone tissue engineering
Authors: Sánchez-Salcedo Sandra , Colilla Montserrat , Izquierdo-Barba Isabel , Vallet-Regí María
Published: January 2016

Bone implant infection constitutes a major sanitary concern which is associated to high morbidity and health costs. This manuscript focused on overviewing the main research efforts committed up to date to develop innovative alternatives to conventional treatments, such as those with antibiotics. These strategies mainly rely on chemical modifications of the surface of biomaterials, such as providing it of zwitterionic nature, and tailoring the nanostructure surface of metal implants. These surface modifications have successfully allowed inhibition of bacterial adhesion, which is the first step to implant infection, and preventing long-term biofilm formation compared to pristine materials. These strategies could be easily applied to provide three-dimensional (3D) scaffolds based on bioceramics and metals, of which its manufacture using rapid prototyping techniques was reviewed. This opens the gates for the design and development of advanced 3D scaffolds for bone tissue engineering to prevent bone implant infections.
Polyelectrolyte gelatin-chitosan hydrogel optimized for 3D bioprinting in skin tissue engineering
Authors: Ng Wei Long , Yeong Wai Yee , Naing May Win
Published: January 2016

Bioprinting is a promising automated platform that enables the simultaneous deposition of multiple types of cells and biomaterials to fabricate complex three-dimensional (3D) tissue constructs. Collagen-based biomaterial used in most of the previous works on skin bioprinting has poor printability and long crosslinking time. This posed an immense challenge to create 3D constructs with pre-determined shape and configuration at high throughput. Recently, the use of chitosan for wound healing applications has attracted huge attention due to its attractive traits such as its antimicrobial properties and ability to trigger hemostasis. In this paper, we optimized polyelectrolyte gelatin-chitosan hydrogel for 3D bioprinting. Modification to the chitosan was carried out via the oppositely charged functional groups from chitosan and gelatin at a specific pH of ~pH 6.5 to form polyelectrolyte complexes. The polyelectrolyte hydrogels were evaluated in terms of physical interactions within polymer blend, rheological properties (viscosities, storage and loss modulus), printing resolution at varying pressures and feed rates and biocompatibility. The polyelectrolyte gelatin-chitosan hydrogels formulated in this work was optimized for 3D bioprinting at room temperature to achieve high shape fidelity of the printed 3D constructs and good biocompatibility with fibroblast skin cells.

Published: January 2016

O presente artigo trata da socialização (didática) de parte de nossos estudos sobre a “etnografia” na área educacional. Inicialmente, apresentamos o histórico dos estudos etnográficos e suas origens na Antropologia, na primeira metade do século XX, com Malinowski e Franz Boas. Em seguida, refletimos sobre o processo de tradução cultural da pesquisa etnográfica, que primeiramente migrou das Ciências Sociais para as Humanas, na Califórnia, em 1954, e que chegou ao Brasil em 1970. Diante desse caráter híbrido da metodologia, descrevemos algumas das concepções que circunscrevem a etnografia em educação e os (des)encontros entre alguns teóricos que a difundem, seja quanto à nomenclatura ou no que se refere ao tratamento das informações.
Microbomba: desenvolvimento e aplicações
Authors: Neto Arlindo Garcia de Sá Barreto , Lira Valnyr Vasconcelos , Moreira Cleumar Da Silva
Published: January 2016

A introdução de agentes farmacológicos no corpo humano tem sido o foco inicial da pesquisa em sistemas de propulsão de microfluxo, conhecidos na literatura como microbombas, com vazões da ordem de 1 μl/min até 100 μl/min. No entanto, as microbombas possuem aplicações em outras áreas, como na refrigeração de circuitos microeletrônicos e, mais recentemente, em sistemas miniaturizados para análises químicas e bioquímicas. Com o aperfeiçoamento das técnicas de manufatura de dispositivos microfluídicos, surgiu o conceito de LOC (Lab-on-Chip), sendo todo o procedimento de análise realizado em um único dispositivo, que contém um sistema de propulsão de fluido (microbomba) e local para preparação, manipulação e análises de amostras, tudo integrado e miniaturizado. A primeira parte desse complexo sistema de análise está relacionada ao transporte do analito, da entrada até a região de detecção, sendo realizada por algum tipo de microbomba. Assim, este trabalho traz um resumo sobre os dispositivos mais usados na literatura, seus mecanismos de atuação e atuadores, tipos de válvulas e o processo de manufatura, abordando características históricas até os dias atuais.

Uso do dióxido de enxofre na despesca e beneficiamento de camarão
Authors: Andrade Luciana Trigueiro de , Lacerda Maria de Fátima Alves Figueiredo de , Ventura Ana Paula Moraes
Published: January 2016

O dióxido de enxofre (SO2) é amplamente empregado após a despesca do camarão para a prevenção do escurecimento que ocorre naturalmente durante seu armazenamento, a melanose. Ele age diretamente no processo de oxidação, inibindo a atividade do complexo enzimático que catalisa a reação de escurecimento. O objetivo do presente artigo foi analisar a importância e variação do uso do SO2 na despesca e beneficiamento do camarão, assim como as conseqüências da ingestão deste aditivo, além de fornecer dados, a partir da revisão de literatura realizada, sobre os fatores que exercem influência na absorção do SO2 pelo músculo do camarão. Dessa forma, foi possível inferir que, na prática, não existe uma padronização quanto a concentração final de SO2 no músculo do camarão, resultando, muitas vezes, em teores acima do recomendado pela legislação brasileira (0,1 g Kg-1), podendo causar danos tanto à saúde do consumidor quanto do manipulador deste aditivo, além de, dependendo da forma como o mesmo for descartado, impactar o meio ambiente.

Authors: Ismael L. L. , Garcia H. R. M. , Martins W. A. , Augusto J.
Published: January 2016

O trabalhador rural está exposto a diferentes situações de riscos durante o desenvolvimento de suas atividades no campo. Uma delas refere-se ao manuseio e aplicação incorreta de agrotóxicos, o que acaba por provocar sérios danos á saúde, não apenas do próprio agricultor mais da população local por consumir alimentos contaminados e ao ambiente. Para isto, o objetivo geral dessa pesquisa foi realizar um levantamento bibliográfico acerca dos riscos advindos das atividades agrícolas quanto ao uso de agrotóxicos. Os resultados evidenciaram que grande parte dos acidentes de trabalho, estão associados à utilização incorreta dos EPIs, além da falta de informação e treinamento dos agricultores para desenvolver tais atividades. Nesse contexto, medidas de caráter preventivo e corretivo deverão ser tomadas para a redução do uso e exposição aos agrotóxicos, para isso, devem ser implementadas no ambiente de trabalho ações socioeconômicas, políticas e ambientais.

Health, environment and safety associated with the use of pesticides

ABSTRACT - The rural worker is exposed to different risk situations while developing their activities in the field. One of them refers to the incorrect handling and application of pesticides, which ultimately cause serious damage to health, not just the very best of the local population farmer by consuming contaminated food and the environment. For this, the general objective of this research was to conduct a literature review about the risks arising from agricultural activities on the use of pesticides. The results showed that most industrial accidents are related to improper use of PPE, as well as lack of information and training of farmers to develop such activities. In this context, preventive and corrective nature of measures should be taken to reduce the use and exposure to pesticides, so it should be implemented in the workplace actions socioeconomic, political and environmental.
ADAT BADAMAI MENURUT UNDANG-UNDANG SULTAN ADAM DAN IMPLEMENTASINYA PADA MASYARAKAT BANJAR PADA MASA MENDATANG
Authors: Hasan Ahmadi
Published: January 2016

Tulisan ini melakukan telaah terhadap adat badamai yang terdapat dalam Undang-undang Sultan Adam berikut kemungkinan implementasinya di kemudian hari. Kajian terhadap Adat badamai adalah salah satu bentuk penyelesaian sengketa yang lazim dilakukan oleh masyarakat Banjar. Adat badamai menggambarkan budaya timur yang akrab dengan nilai-nilai atau pandangan masyarakat yang bercirikan solidaritas mekanis, dalam kondisi seperti ini adat badamai fungsional dan sangat tepat sebagai mekanisme solutif dalam menyelesaikan berbagai masalah dalam msyarakat. Ketika masyarakat berubah sesuai dengan perubahan dan modernisasi yang terjadi, maka posisi adat badamai masih mendapat tempat dalam aspek keperdataan yaitu ketika berada dalam ruang dan tatanan masyarakat yang bercirikan solidaritas organis, yang lebih mengandalkan mekanisme penyelesaian sengketa dengan pendekatan litigasi. Namun dalam aspek pidana tampaknya pendekatan adat badamai tidak dapat difungsikan, kecuali pada masyarakat pedesaan yang masih akrab dengan solidaritas mekanis. Ke depan posisi adat badamai cukup prospektif dan masih tetap dipertahankan oleh masyarakat, meskipun masih perlu mendapat dukungan dari masyarakat sendiri untuk memperjuangkan dan mungupayakan pelestarikan nilai-nilai adat badamai sebagai hukum yang hidup pada masyarakat.

Spatial Variability in Biomass Yield of Switchgrass, Native Prairie, and Corn at Field Scale
Authors: Hao Xinmei , Thelen Kurt , Gao Juan
Published: January 2016

Evaluating biofuel crop yield and its spatial variability on a field scale is important for determining the proper bioenergy crops suitable for specific lands. Within field spatial variability of switchgrass (Panicum virgatum L.), native prairie mix, and corn (Zea mays L.) biomass yield and its relation to soil properties were investigated in 2011 and 2012 at two farms in southwestern Michigan. At all sites and years, the order of biomass yields was corn > switchgrass > native prairie, which was consistent with fertilization rates of the crops. Short stand age of the perennial grass also contributed to the relatively lower yield. At both sites, switchgrass yield was not significantly different between 2011 and 2012, while corn yield was significantly lower in 2012 than in 2011. For switchgrass, within‐field variation was found considerably larger than the variation between years or between sites, while the variation between years or sites were comparable or greater than the within field variation for corn or native prairie. Two factors extracted from partial least square regressions (PLSRs) between biomass yield with soil and topographic variables could explain the majority of within field spatial variation for most of the fields in the study. Weight values of predictor variables from PLSRs were found strongly correlated between the 2 yr for a given crop at the same site with correlation coefficients from 0.65 to 0.89, as well as between switchgrass and native prairie at a given site.
Establishing Switchgrass with a Corn Companion Crop to Improve Economic Profitability

Published: January 2016

Establishing switchgrass (Panicum virgatum L.) usually takes 2 yr, and revenue is not typically generated from the land until the end of the second year. Much is already known about establishing switchgrass as a bioenergy or forage crop, but identifying additional methods of establishment that provide revenue during the planting year without negatively impacting long‐term stand density or biomass yield would better incentivize farmers to convert portions of land to growing switchgrass. A field experiment was conducted to evaluate the impact of companion corn (Zea mays L.) seeding rate (49, 59, and 69 ×103 seeds ha−1) and establishment year N fertilizer rate (0, 112, and 224 kg N ha−1) on corn yield, switchgrass stand density, second‐ and third‐year biomass production, and the net economic return over the 3‐yr establishment period. Switchgrass stand densities averaged 5 plants m−2 fewer when companion cropped with corn compared with switchgrass planted alone (25.9 plants m−2), but all treatments resulted in successful stands with at least 17 plants m−2. Net annual economic return over the 3‐yr establishment period was maximized under most price scenarios when switchgrass was companion cropped with corn fertilized with 112 or 224 kg N ha−1 during the establishment year. These results confirm that switchgrass can be established with corn to improve short‐term net economic returns without negatively affecting long‐term switchgrass stand health.
Modelling Needs for Mental Healthcare from Epidemiological Surveys with Validation Using Sociodemographic Census Data
Authors: Kovess-Masfety Viviane , Boyd Anders
Published: January 2016

Purpose: To develop and validate a prediction model for mental health needs (MHN) and psychiatric needs (PN) using specific social indicators, obtainable from census data, within low-density departments (LDD) and high- density departments (HDD).Methods: In a population-based study of 20,404 participants from 22 departments in France, mental health needs were defined into three categories (no needs, MHN, and PN) using the Composite International Diagnosis Interview Short-Form, Sheehan disability scale, and presence of depressive and alcohol disorders. Within HDD (n=9) and LDD (n=13) departments, two separate logistic regression models, using MHN or PN as an endpoint, were fitted using available sociodemographic data. Model validation was performed using 2007 census data. Overall accuracy was evaluated using average residuals (AR) calculated within density stratum.

Results: In LDD and HDD respectively, 26.6% and 28.7% of persons had MHN and 9.8% and 11.3% had PN. In LDD, housing type, age, employment, living alone, housing support, and household size predicted MHN and PN. In HDD, housing type, living alone, household size, living in a marriage/partnership, and duration of dwelling habitation predicted MHN and PN. Predictions were more accurate in HDD, in which the AR was 30% lower for MHN and 40% lower for PN. Predictions were less accurate when using census data, yet they were consistently better in HDD.

Conclusions: Sociodemographic indicators from either survey or census data may be useful in predicting MHN and PN in high-density settings. The ideal territorial size still needs to be evaluated when planning psychiatric and mental health resources.
Application of an R-group search technique into molecular design of HIV-1 integrase inhibitors
Authors: Tong Jian-Bo , Bai Min , Zhao Xiang
Published: January 2016

In this paper, a three-dimensional quantitative structure-activity
relationship (3D-QSAR) study for 62 HIV-1 integrase(IN) inhibitors was
established using Topomer CoMFA. The multiple correlation coefficient of
fitting, cross validation and external validation were 0.942, 0.670 and
0.748, respectively. The results indicated that the Topomer CoMFA model
obtained has both favorable estimation stability and good prediction
capability. Topomer Search was used to search R group from ZINC database. As
the result, a series of R groups with relatively high activity contribution
was obtained. By filtering with the most potent molecule in the set, 1 Ra
group and 21 Rb groups were selected. We employed the 1 Ra groups and 21 Rb
groups to alternately substitute the Ra and Rb of sample 42. Finally, we
designed 21 new compounds and further predicted their activities using the
Topomer CoMFA model and there were 10 new compounds with higher activity than
that of the template molecule. The results suggested the Topomer Search
technology could be effectively used to screen and design new HIV-1 IN
inhibitors and has good predictive capability to guide the design of new
HIV/AIDS drugs.
Global regularization method for planar restricted three-body problem
Authors: Sharaf M.A. , Dwidar H.R.
Published: January 2016

In this paper, global regularization method for planar restricted three-body
problem is purposed by using the transformation z = x+iy = ? cos n(u+iv),
where i = ??1, 0 < ? ? 1 and n is a positive integer. The method is developed
analytically and computationally. For the analytical developments, analytical
solutions in power series of the pseudotime ? are obtained for positions and
velocities (u, v, u', v') and (x, y, x?, y?) in both regularized and physical
planes respectively, the physical time t is also obtained as power series in
?. Moreover, relations between the coefficients of the power series are
obtained for two consequent values of n. Also, we developed analytical
solutions in power series form for the inverse problem of finding ? in terms
of t. As typical examples, three symbolic expressions for the coefficients of
the power series were developed in terms of initial values. As to the
computational developments, the global regularized equations of motion are
developed together with their initial values in forms suitable for digital
computations using any differential equations solver. On the other hand, for
numerical evolutions of power series, an efficient method depending on the
continued fraction theory is provided.
Application of biochar and fate of soil nutrients
Authors: Khan KT , Chowdhury MTA , Huq SM Imamul
Published: January 2016

An in vitro incubation study was conducted with soil having seven applications of different treatments of biomass and biochar including a control. The biochar and biomass were applied at a rate of 5 t/h a and incubated at field moisture condition for 30, 60 and 90 days individually in different pots. Total organic carbon (C), total nitrogen, phytoavailable nitrogen (N), phosphorus (P), sulfur (S) and potassium (K) were determined at the end of each incubation period. Total soil organic carbon (SOC), showed a substantial declining trend in all the soils - more prominent in the biochar treated soils than its corresponding biomass treated soils. The pH, total N, phytoavailable N, P, K were substantially higher in the biochar treated soils irrespective of the incubation days compared to the biomass treated soils. Conversely, the available S contents of the biochar treated soils were lower than that of biomass treated soils. The effect of biochar on these nutrients vis-à-vis soil health is discussed.Bangladesh J. Sci. Res. 27(1): 11-25, June-2014

Published: January 2016

The paper intends to provide guidance to evaluate and identify a standard ground water chemistry data for irrigation in south western region of Bangladesh. During the course of hydrogeological studies in the study area, twenty water samples were collected from twenty different villages and chemically analyzed. The analytical results revealed that the water was slightly acidic to slightly alkaline (pH 6.68 - 7.32) and TDS values range from 565 to 1073 mg/l. The other parameters like sodium adsorption ratio, (SAR) (0.10 - 0.27), sodium percentage (3.22 - 7.13), residual sodium carbonate, (RSC) (3.2 - 5.33) and potential soil salinity, (PS) (less than 30) were below the desired limit suggesting the suitability for irrigation purpose. Considering SAR, permeability index and salinity hazard, all waters could be applied safely for irrigation without any hazard to crops.Bangladesh J. Sci. Res. 27(2): 121-131, December-2014

Ellipsoidal mixture models for clustering: an application to web-based education data
Authors: Jafreen Saujanna , Mallick Taslim S , Khan Jafar A
Published: January 2016

This study considers the Gaussian mixture models for clustering. Since spherical and diagonal models occur very rarely in practice and analysis can be simplified when these models are implemented, we focus on the ellipsoidal models. EM algorithm is used to fit these models to a real data set related to an adaptive educational electronic course. Misclassification rates and Bayesian Information Criteria (BIC) values are used for comparison.Bangladesh J. Sci. Res. 28(1): 1-7, June-2015
Lead and cadmium accumulation in nearby brick kiln agri-environmental ecosystems
Authors: Sikder Abdul Halim Farhad , Molla Md Delwar Hossain , Hossain Md Faruque , Parveen Zakia
Published: January 2016

Three different brick kilns from the same parent material, young Brahmaputra and Jamuna floodplain were selected to assess the lead and cadmium accumulation. Soils and plants from four points such as 250, 500, 1000 and 1500 m away from kilns were collected based on the predicted brick kilns emission distance. Lead (92 mg kg-1 to 214 mg kg-1) was found in the elevated levels near brick kiln soils. The alarming news is that plant uptake of Pb in the nearest areas of the brick kilns were significantly higher than the areas far from the brick production location and Pb ranges from 7 to 543 mg/kg. Results showed that both soils and plants from 500 m to 1000 m distance received maximum Pb. The amount of Pb significantly decreases with the increasing distance from the brick kilns. Cadmium varies within the permissible limit in both soils and plant.Bangladesh J. Sci. Res. 28(1): 51-59, June-2015
