Using Semantic Web for Internet of Things Interoperability
Authors: Andročec Darko , Novak Matija , Oreški Dijana
Published: August 2018

The main vision of the Internet of Things (IoT) is to enable seamless connection between physical devices and information systems to improve the lives of people. One of the main obstacles to achieve this vision is the current lack of IoT interoperability. In this article, the authors are giving an overview on how semantics is used in IoT interoperability related research. To do this, they performed a systematic literature review and extracted data from 105 selected primary studies dealing with semantics in IoT interoperability. The authors have analysed the maturity level of this research field and when and where the relevant works were published. This article answers five main research questions about the following issues: what are semantics used for; what types of ontologies exist (which are used to give semantical descriptions); what are the main themes and suggestions for future work in these research articles; and what are other related areas.
Are we wired for spirituality? An investigation into the claims of neurotheology
Authors: Kyriacou Demetrios
Published: August 2018

This article is an investigation into the field of neurotheology, a controversial field which has attracted criticism from both the scientific and religious community and which is often quite divided among its own practitioners. Regretfully, but not too unexpectedly, science has gotten entangled with ideology, as we shall see, with proponents on all sides of the spectrum using findings from the laboratory in support of their own philosophical positions. We will begin by exploring some definitions of the field and then move on to examine the claims made by the different scientists working in this area, before examining what conclusions we can draw for spirituality.
Awareness of predatory journals among physicians from Africa and the middle East: An exploratory survey
Authors: Beshyah Salem , Hajjaji Issam , Elbarsha Abdulwahab
Published: August 2018

Objectives: There is a recent proliferation of predatory journals (PJ) targeting unwary authors and unsuspecting institutions. We evaluated the awareness, attitude, and practices related to predatory publishing among physicians from the Middle East and Africa. Subjects and Methods: An online survey of a convenience sample of physicians was conducted. One hundred and forty responses were received. Of these 76 were complete and they formed the basis of this study. Results: Respondents hold a specialty board or equivalent (46.1%), doctorate (26.3%) or Master (13.2%). Half of the respondents published between 1 and 10 articles and less than a fifth had no prior authorship experience. Respondents are reportedly fully aware (30.3%) or fairly familiar but were not confident with details (43.4%), whereas 26.3% have no clear idea about models of publishing (open access [OA] vs. subscription-only). Nearly one third have never heard about predatory publishing and one in six of the respondents may have heard about it, but they were not sure. 69.7% reported no knowledge of Jeffery Beall and his list. The majority thought it might be somewhat difficult (51.4%) or difficult (24.3%) to distinguish between predatory and legitimate OA journals and 40%–60% affirmed knowledge of features of predatory publishing practices. 50%–60% recognized that PJ target authors in the developing nations. Respondents reported a variable frequency of unsolicited E-mails inviting them to submit articles to suspected PJ or act as reviewers or editors. Only a minority would take further action to protest against such invitations. Many respondents suggested warning young researchers and inexperienced authors about PJ by improved supervision and mentorship practices. Conclusions: There is a low awareness of predatory publishing. There were varying attitudes and practices among respondents.
Ocular manifestations in patients attending antiretroviral therapy centre at a tertiary care hospital in Himachal Pradesh, India
Authors: Sharma Mukta , Chauhan Anil , Sharma Gaurav , Chauhan Vivek
Published: August 2018

Background & objectives:

Ocular manifestations in HIV/AIDS patients range from adnexal disorders to the posterior segment disease. This study was aimed to evaluate the ocular manifestations, including vision-threatening manifestations in HIV-positive patients attending an antiretroviral therapy centre (ART) of a tertiary care hospital in north India and its association with the CD4+ cell count.

Methods:

This cross-sectional study was conducted in the department of Ophthalmology in collaboration with the ART centre. An equal number of patients were selected from each year i.e., 30 patients each from those registered in the year 2010 till 2015. These patients were selected randomly from the register using systematic randomization. Hence, a total of 150 patients were examined for ocular manifestations. All the patients included in this study were on highly active ART.

Results:

Of the 150 patients examined, 53 per cent were females and 47 per cent were males. Heterosexual transmission was the most common mode of transmission in 126 (84%) patients. Maximum number of patients was in the age group of 31-40 yr. Ocular manifestations were present in 53 [35.3%; 95% confidence interval (CI): 28-43%] patients. Twelve (8%; 95% CI: 4-12%) patients had lid and adnexal manifestations. Anterior-segment manifestations were present in 20 (13.3%; 95% CI: 8-19%) patients. Posterior-segment manifestations were present in 21 (14%; 95% CI: 8-20%) and vision-threatening posterior-segment ocular lesions were present in 14 per cent of the patients. Univariate logistic regression showed a significant (P <0.001) inverse association of CD4+T-cell count with the vision-threatening posterior-segment ocular lesions.

Interpretation & conclusions:

Routine ocular examination may be done in all the HIV/AIDS patients to detect and treat vision-threatening ocular lesions at the earliest.

Published: August 2018

Background & objectives:

Data on bone mineral density (BMD) and sarcopenia are scant from young females with HIV. This study was conducted to determine occurrence, predictors and impact of body composition alterations on osteoporosis in pre-menopausal women with HIV.

Methods:

A total of 214 females with serologically documented HIV infection were screened, of whom 103 pre-menopausal women, 25-45 yr age, clinically stable, having at least one year follow up data, underwent hormonal and dual-energy X-ray absorptiometry analysis for BMD and body composition. Seventy five matched controls were also evaluated.

Results:

Females with HIV had significantly lower BMD and Z-score at lumbar spine (LS), total femur, neck of femur (NOF), and radius ultra-distal (UD) compared to controls. Osteoporosis at least at one site was observed in 34.95 per cent patients, compared to eight per cent in controls (P <0.001). Most common site of osteoporosis in females with HIV was radius UD (24.27%), followed by radius 33 per cent (17.48%), radius total (15.53%) and greater trochanter, NOF and LS (6.80% each). HIV patients had significantly lower bone mineral content, lean mass (LM), fat per cent, android (A) fat, gynoid (G) fat, and A/G ratio. LM and fat mass (FM) were −15.65 and −11.54 per cent lower in HIV patients, respectively. Osteoporosis patients had significantly higher use of antiretroviral therapy and lower LM, FM and fat per cent. On logistic regression, LM followed by A/G ratio and BMI were the best predictors of osteoporosis. Sarcopenia was observed in 17.5 per cent patients.

Interpretation & conclusions:

Our results showed that osteoporosis and sarcopenia were significant problems in young women with HIV. HIV was associated with greater LM loss, which was critical for bone health. Sarcopenia may predict low BMD in HIV.
Genotyping & diagnostic methods for hepatitis C virus
Authors: Kumar Anoop , Rajput Manoj Kumar , Paliwal Deepika , Yadav Aakanksha , Chhabra Reba , Singh Surinder
Published: August 2018

Hepatitis C virus (HCV) infection is a blood borne and transfusion-transmitted infection (TTI). It has emerged as one of the major health challenges worldwide. In India, around 12-18 million peoples are infected with HCV, but in terms of prevalence percentage, its looks moderate due to large population. The burden of the HCV infection increases due to lack of foolproof screening of blood and blood products before transfusion. The qualified screening and quantification of HCV play an important role in diagnosis and treatment of HCV-related diseases. If identified early, HCV infection can be managed and treated by recently available antiviral therapies with fewer side effects. However, its identification at chronic phase makes its treatment very challenging and sometimes ineffective. The drugs therapy for HCV infection treatment is also dependent on its genotype. Different genotypes of HCV differ from each other at genomic level. The RNA viruses (such as HCV) are evolving perpetually due to interaction and integration among people from different regions and countries which lead to varying therapeutic response in HCV-infected patients in different geographical regions. Therefore, proper diagnosis for infecting virus and then exact determination of genotype become important for targeted treatment. This review summarizes the general information on HCV, and methods used for its diagnosis and genotyping.
Animal models of tuberculosis
Authors: Singh Amit Kumar , Gupta Umesh D.
Published: August 2018

Tuberculosis (TB) remains a leading cause of death globally among infectious diseases that has killed more numbers of people than any other infectious diseases. Animal models have become the lynchpin for mimicking human infectious diseases. Research on TB could be facilitated by animal challenge models such as the guinea pig, mice, rabbit and non-human primates. No single model presents all aspects of disease pathogenesis due to considerable differences in disease resistance/susceptibility between these models. Availability of a wide range of animal strains, Mycobacterium tuberculosis strains, route of infection and doses affect the disease progression and intervention outcome. Different animal models have contributed significantly to the drug and vaccine development, identification of biomarkers, understanding of TB immunopathogenesis and host genetic influence on infection. In this review, the commonly used animal models in TB research are discussed along with their advantages and limitations.
Environmental performance of a full-scale wastewater treatment plant applying Life Cycle Assessment
Authors: Lopes Thaís Andrade de Sampaio , Queiroz Luciano Matos , Kiperstok Asher
Published: August 2018

Life Cycle Assessment (LCA) was applied to estimate and analyze the environmental impacts from the construction and operation phases of a full-scale wastewater treatment plant (WWTP) located in the municipality of Lauro de Freitas, Bahia, Brazil. The WWTP process consists of the association of an Upflow Anaerobic Sludge Blanket (UASB) reactor followed by four constructed wetlands (CWL) and a disinfection step. The functional unit was defined as one cubic meter of treated effluent during the useful life of this WWTP (20 years). The LCA was carried out using SimaPro® software and the Centre of Environmental Science (CML) assessment method. The environmental impacts during construction phase were mainly from the wooden forms for concrete and the use of reinforcing steel. During the operation phase, the chlorine used as effluent disinfectant caused the greatest impacts in the abiotic depletion and acidification categories. Macronutrient concentrations present in the treated effluent and the methane generated also caused significant environmental impacts during the WWTP’s useful life. The results obtained highlight the importance of the application of a methodology like LCA to assist in decision-making with regard to the implementation, construction and operation of a WWTP.

Authors: Narasimha Murthy I , Sivaprasad K , Babu Rao J
Published: August 2018

Research was conducted to build up the minimal cost nano-crystalline Pb open solder alloy by means of superior strength and compact melting temperature. In this research, a minimal cost lead-liberated solder alloy of Sn-0.7Cu was selected. Elevated energy ball milling method was assumed for the manufacture of nano crystalline solder from this alloy. The milling was conducted for 100 hrs. The milled powders were considered for their crystallite size, changes in morphology as well as decline in its melting temperatures. The outcome reveals that for a milling time of 100 hrs the crystallite size was lessened from 131 nm to 36 nm. DSC evaluations reveal a steady transition from pointed exothermic peak in bulk alloy to broad depleted temperature summits at lessened particle sizes. Nano crystalline powder was compacted into billets with a 98% theoretical compaction density. Microwave sintering technology was adopted to sinter these compacted billets. A series of tests like SEM-EDS, XRD, DSC, salt spray fog corrosion studies, density measurements, mechanical properties like hardness, compression, shear and tensile tests were carried out on these solder billets. Results shows that conversion from micro to nano crystalline structure improved mechanical and corrosion resistance was noticed while lowering the melting temperature.Keywords: Pb free solders, High energy ball milling, Nano crystalline materials, Low melting point

Familias homoparentales: ¿Reproducción o transgresión del género hegemónico?
Authors: Cruz María Angélica , Llantén Oyarce Marian
Published: August 2018

En este artículo buscamos, primero, comprender cómo las familias homoparentales reproducen y/o tensionan las normas hegemónicas del género y, segundo, si ello cambia al participar en colectivos del movimiento homosexual. Metodológicamente trabajamos con entrevistas a un grupo de adultos de este tipo de familias. Los resultados muestran múltiples trayectorias para llegar a ser familias homoparentales y distintos modos de (in)visibilizarlas. En todas ellas el género hegemónico se reproduce buscando garantizar el bienestar de los/as hijos/as; no obstante, entre quienes participan en colectivos encontramos ciertas prácticas que lo tensionan o desacatan, particularmente en casos de maternidades lésbicas asistidas tecnológicamente. Así, concluimos que la sola existencia de familias homoparentales cuestiona los supuestos básicos sobre la sexualidad y el género, pero ello no garantiza la transgresión del orden hegemónico del género.
Explaining outcomes of asymmetric conflicts revisited: The Arauco War
Authors: Disi Pavlic Rodolfo
Published: August 2018

This article evaluates two theories that seek to explain the outcomes of asymmetric conflicts. It uses evidence from a case study of the Arauco War (1536-1883). The war resulted, unlike most other instances of European colonization, in the victory of the weaker side. The first theory argues that in asymmetrical warfare, opponents choose between direct (conventional) and indirect (guerrilla) approaches; the stronger side is more likely to win same-approach interactions, while the weaker side is more likely to prevail in different-approach interactions. The second theory advances the claim that when armies become mechanized, they gather less intelligence from the ground, and are therefore less likely to solve the information problem - telling combatants apart from noncombatants. The analysis of the Arauco War shows the limitations of the first theory: the stronger side can easily win some different-approach (indirectdirect) interactions, while the weaker can win same-approach (indirect-indirect) ones. The study lends support to the second theory, especially once it is generalized to include cultural differences as factors that exacerbate the identification problem.

Authors: Magalhães Bruna Corrêa , Vieira Patricia Maria , Aramaki Alberto Luiz , Kososki Edinara , Martins Silva e Dutra Fabiana Caetano
Published: August 2018

Este estudio tuvo como objetivo analizar la relación entre la percepción de la salud, estilo de vida y el comportamiento ocupacional de universitarios. La percepción de la salud se evaluó mediante una variable categórica con escala que va desde "muy bueno" a "muy malo". El estilo de vida y el comportamiento ocupacional fueron medidos por los instrumentos "Estilo de Vida Fantástico" y "Auto Evaluación del Funcionamiento Ocupacional". Los datos se sometieron a análisis descriptivo y la correlación con el nivel de 5% de confianza. La muestra fue constituida por 56 estudiantes, 87,5% son mujeres, edad media 20 años, y regularmente matriculados en los cursos de salud (85,7%). De estos estudiantes, 38,2% percibe su salud como "regular" a "muy malo" y 10,7% han clasificado su estilo de vida como "buena" y "necesitan mejorar". Se encontró diferencia entre el estilo de vida y la percepción de la salud (p=0,016). La percepción de la salud y el funcionamiento ocupacional tenía diferencia en Hábitos (p=0,028) y Medio Ambiente (p=0,040). Al comparar el funcionamiento ocupacional con el estilo de vida, ocurrió diferencias en la Causalidad Personal (p=0,039), Valores (p=0,001), Intereses (p=0,001) y Funciones (p=0,000). Los resultados del estudio apoyan la conclusión de que existen asociaciones significativas entre la auto percepción negativa de la salud con un peor estilo de vida y el comportamiento en el trabajo entre los estudiantes universitarios.
Interações entre a psicopedagogia, a filosofia e a teoria crítica do direito: A busca de um novo critério de validade discursiva em Paulo Freire
Authors: Ruppert Krubniki João Pedro
Published: August 2018

O presente artigo tem por objetivo analisar determinadas correntes teóricas da psicopedagogia do século XX e sua inserção nos paradigmas filosóficos vivente e da linguagem, demonstrando em que medida elas se inserem ou divergem em relação aos mesmos. Em um primeiro momento, são traçadas considerações acerca do surgimento de novos paradigmas filosóficos no século XX (o paradigma da linguagem e o paradigma vivente). Após, analisam-se algumas correntes teóricas elaboradas no campo da psicopedagogia (são analisadas as posições de Jean Piaget, Lev. S. Vygotsky e Paulo Freire), traçando a relação que essas teorias possuem com os paradigmas filosóficos. Por fim, a partir de uma análise que confere ênfase às ideias de Paulo Freire, busca-se demonstrar a possibilidade de criação de um discurso contra-hegemônico no campo jurídico, perquirindo os reflexos que a aplicação dessa teoria acarreta na teoria crítica do direito.
Hacia un currículo ambientalmente sustentable para las carreras de Derecho
Authors: Arnouil Seguel Mónica
Published: August 2018

Los currículos universitarios de pregrado en Derecho presentan un bajo nivel de inclusión ambiental, tema preocupante en un contexto educativo formador, por cuanto son precisamente los instrumentos de gestión educativa a través de los cuales se logra definir e integrar el contenido ético inmerso en la axiología jurídica y traspasarlo a las aulas en una perspectiva de formación profesional. Desde un modelo educativo de adscripción neoliberal, Chile ha delineado la concepción curricular hacia la eficacia pedagógica, enfoque que lo ha visibilizado como un país con alta oferta para la educación superior universitaria, pero no necesariamente en proporcionar al estudiante los conocimientos necesarios para su futuro laboral. Todo esto resulta paradójico en un país con alta tasa de conflictualidad ambiental y un legado político-social de privación de derechos, que, a lo menos, debe refocalizar las políticas públicas hacia un discernimiento ético-educativo, garante de los principios axiológicos de la acción educativa.
Os saberes mobilizados pelo bom professor na visão de alunos concluintes do curso de direito
Authors: Ribeiro Adilson José , Buzzi Rausch Rita
Published: August 2018

O presente artigo apresenta os resultados de uma pesquisa que objetivou compreender, por meio dos dizeres dos alunos do Curso de Direito da Universidade Regional de Blumenau – FURB, suas percepções acerca do bom professor para o Curso de Direito. A coleta de dados foi realizada com setenta e três alunos concluintes do curso, por meio de um questionário, com a utilização da técnica do complemento. A pesquisa foi de cunho qualitativo e a análise de conteúdo dos dados pautou-se principalmente nos estudos de Clermont Gauthier, Álvaro Marchesi, Claude Lessard, Maurice Tardif, António Nóvoa e Paulo Freire. Em conclusão, os resultados permitiram inferir que para os alunos do Curso de Direito o bom professor mobiliza um conjunto de saberes no contexto educacional em que atua, em especial, os saberes pedagógicos, disciplinares, curriculares e experienciais. Bem como, evidenciou-se que a relação afetiva-emocional é de grande importância na prática do bom professor, pois, esta dimensão é tão vital quanto os saberes científicos, as estratégias de aprendizagem, o compromisso social e moral dos docentes.

TRIAGEM FITOQUÍMICA E ATIVIDADE ANTIBACTERIANA DOS EXTRATOS AQUOSO E HIDROALCOÓLICO BRUTOS DE Jacaranda micrantha Cham. (“CAROBA”) SOBRE CEPAS DE Staphylococcus coagulase positiva E Salmonella spp. PADRÕES E ISOLADAS EM PRODUTOS DE ORIGEM ANIMAL
Authors: Marchionatti Avancini César Augusto , Drebes Tainá , Miranda Ethur Eduardo
Published: August 2018

A resistência microbiana a compostos químicos convencionais, bem como demanda por tecnologias adequadas ao sistema de produção orgânico/agroecológico motivaram o desenvolvimento desta pesquisa na busca de soluções antibacterianas originadas de extrações vegetais. Os objetivos foram realizar screening fitoquímico e avaliar a atividade dos extratos aquoso (EA) e hidroalcoólico (EH) brutos de Jacaranda micrantha Cham. Com o teste de suspensão quantitativo os extratos das folhas nas proporções 5 g : 100 mL, 10 g : 100 mL e 20 g : 100 mL foram confrontados com as cepas Staphylococcus aureus ATCC 25923 e Salmonella Choleraesuis ATCC 10708, e na de  10 g : 100 mL (100 mg/mL) com isoladas em alimentos de origem animal: S. coagulase positiva (N=20) e S. spp. (N=20). As densidades populacionais de confronto (DP) foram 107, 106 e 105 UFC/mL, nos tempo de contato de oito e 24 horas. Análise fitoquímica qualitativa detectou a presença de compostos fenólicos, taninos condensados e flavonas tanto no EA quanto no EH, e de saponinas apenas no EA. Foi praticamente inexistente a atividade antibacteriana do EA. Já o EH, tomando como referência a proporção 10 : 100, nas 24 h de contato inativou as duas cepas padrões (exceção da Salmonella na maior DP). Frente as isoladas, apresentou melhor atividade sobre S. coagulase positiva reduzindo a DP ou inativando 70% delas na 107, 95% na 106 e 100 % na 105 UFC/mL. As evidências mostram que além das variáveis proporção peso : volume, densidade populacional e tempo de confronto, características intrínsecas dos gêneros e dos indivíduos isolados interferiram na atividade dos extratos. Concluiu-se que o EA pouco apresentou atividade antibacteriana, e que o EH apresentou maior efeito microbiológico frente aos gêneros confrontados.

Partindo de excertos sobre temas como “revolução”, “classe trabalhadora”, “engajamento” e “promessa”, analisados nos livros e artigos de Hannah Arendt, pretendo refletir sobre a figura do eu-revolucionário, ilustrado pela autora em diversos momentos de seu trabalho. Trata-se do feito extraordinário (ainda que aquele em pequena escala), realizado pelo homem comum, que se destaca devido a seu compromisso, resistência, oposição. O objetivo deste artigo é, a partir de algumas leituras de Hannah Arendt, discutir os sentimentos e sensibilidades que motivam o engajamento político, sua linguagem e dinâmica interna, tanto quanto a quase inevitável oscilação ente o desejo de liberdade e a disposição à obediência, o sincero amor à causa e a tendência à mentira.

A pesquisa arqueológica na província mais oriental do Canadá se beneficiou de uma longa e expansível história de parcerias com as comunidades. Tal deve-se, em parte, ao mandato excepcional da Memorial University, assim como ao engajamento forte do departamento de arqueologia em trabalhar com indivíduos e organizações locais durante escavações. A partir de três casos de estudos da província de Terra Nova e Labrador, este artigo revela as motivações, as experiências, os desafios, como os resultados que podem surgir das parcerias comunidade-universidade, e atesta do potencial da arqueologia em contribuir localmente de forma vantajosamente.
HURON-WENDAT ARCHAEOLOGICAL HERITAGE: BUILDING RELATIONSHIPS TOWARDS COLLABORATION

Published: August 2018

Existe uma história longa de estudo acadêmico do povo Huron-Wendat no século dezessete no Ontario. Apesar disso, é muito recente o engajamento dos arqueólogos e de outros acadêmicos com a comunidade Huron-Wendat em relação às escavações de sítios Huron-Wendat no Ontario. Este engajamento constitui um primeiro passo, porém não representa uma verdadeira colaboração considerando que na maioria dos casos as investigações não são parcerias e não se baseiam em perguntas diretamente formuladas pelos membros da Nação. Em 2015, para marcar o aniversario de quatrocentos anos da chegada de Champlain no Ontario, membros da Nação Huron-Wendat e arqueólogos co-organizaram um colóquio sobre temas de grande interesse para a Nação, incluindo a relação com os “St. Lawrence Iroquoians,” os Wendat e a história dos Wyandot depois de 1650, assim como análises bio-arqueológicas. Este artigo apresenta uma breve história da pesquisa arqueológica sobre o passado dos Huron-Wendat e revela alguns novos, e mais colaborativos, caminhos de pesquisas presentes e futuras.

Patrimônio é um tema complexo. Pode ser considerado uma maneira de transmitir sabedorias ou ensimanento morais, mas também pode se tornar instrumento importante para desafiar ideias e práticas estabelecidas, provocando o pensamento crítico e a ação. Tudo depende de como entedemos o que é patrimônio. O objetivo central desse artigo é discutir exatamente essa questão, explorando os significados dessa segunda perspectiva: os autores discutirão três estudos de caso no Brasil para arugumentar que cultura material, quando entendida de maneira mais progressiva, pode promover inclusão social e empoderamento.

Water management is main factor that determines the successful of rice cultivation in acid sulphate soil. Soil waterlogging determines the direction and rate of chemical, geochemical and biological reaction in the soil, indirectly these reactions may influence to the changes of soil psycal properties during soil waterlogging process. The experiment was aimed to study the changes of two type of acid sulphate soils physical properties during rice straw decomposition processes.  The  research  was  conducted  in  the  greenhouse  consisting  of  the  three  treatment  factors  using  the completely randomized design with three replications. The first factor was soil type: potential acid sulphate soil (PASS) and actual acid sulphate soil (AASS). The second factor was height of water waterlogging: 0.5-1.0 cm (muddy water–level  condition) and 4.0 cm from above the soil surface (waterlogged). The third factor was organic matter type: rice straw (RS), purun tikus (Eleocharis dulcis) (PT) and mixed of RS and PT (MX). Soil physical properties such as aggregate stability, total soil porosity, soil permeability, soil particle density and bulk density were observed at the end of experiment (vegetative maximum stage). The results showed that acid sulphate soil type had large effect on soil physicl properties, soil waterlogging decreased aggregate stability, soil particle density and bulk density both of soil type.Keywords : Acid sulphate soils, soil physical properties, and waterlogging [How to Cite: Arifin F, A Susilawati and A Rachman. 2014.

A  study  was  conducted  to  assess  nutrient  dynamics  of  soils  under  old  and  young  cocoa,  coffee  and  cashew plantations and the leaf nutrient contents of the crops at Uhonmora, Edo State, Nigeria for proper cultural and soil fertility management of the plantations. Soil and crop leaf samples were collected from each plantation using a random sampling technique. The samples were analyzed using standard procedures for sand, silt, clay, pH (H2O), electrical conductivity (EC), total N, available P, K, Ca, Mg, Na, and Effective Cation Exchange Capacity (ECEC). Leaf samples were analyzed for N, P, K, Ca, Mg and Na. Data were compared with the corresponding soil and foliar critical nutrient values for each crop. Results indicated that the soils were texturally sandy clay loam and acidic. The soils varied in their nutrient contents, with soil P for the old cocoa, young coffee and cashew plantations far below critical values. The young cashew plot was low in N content but adequate for other plots. However, the soil ECEC increased with the increasing of calcium contents. Leaf N was below critical for all the crops. Leaf K was low for cocoa and coffee plants, leaf Ca was low for the young cashew plants, while leaf Mg was low for the young cocoa and old cashew. The high soil Mg/K ratio of 8.7- 22.3 as against the established value of 2.0 might have resulted in gross nutrient imbalance which must have affected the absorption and utilization of other nutrients. Hence, adequate soil N did not translate the same availability to the crops. The ECEC showed that the soil needs to be improved upon for sustainable  productivity.  Soil  nutrient  content  variation  across  the  plantations  with  age  of  establishment  will necessitate the need for consistent routine soil nutrient assessment for proper and balanced soil nutrient supply to the  crops,  for  healthy  crop  growth  and  optimum  yield.    Management  practices  of  soil  surface  mulching  using organic wastes and cover crops under compatible cropping systems are needed for successful plot establishment and better growth performance of the young seedlings.Key words: Nutrient dynamics, plantation crops, rehabilitation, soil fertility management [How to Cite: Rotimi RI and JS Ogeh. 2014.

Vegetation has a strong influence on soil characteristics. Vegetation can contribute organic matter sand nutrients to the soil. This study aimed to assess soil fertility through various approaches physical and chemical soil on various types of cover crop in the  arboretum area at University of Lampung, and determined the type of cover crop that had the best effect on soil fertility. The research was be conducted by a survey method, which made observations on the soil characteristics of six species of cover crops following were rosewood (Dalbergia latifolia), teak (Tectona grandis), albizia (Paraserianthes Albiziaria), acacia (Acasia mangium), fern tree (Filicium desipiens), and mahogany (Swietenia macrophylla King). Soil characteristics observed data were the physical and chemical properties, obtained by field observations, through boring profiles and soil sampling. The results showed that soil fertility on rosewood, albizia, acacia and mahogany on campus area of Lampung University had contents of soil organic C, organic matter, and soil total N higher than teak and Fern tree. Litter from Rosewood, Albizia, and acacia had the best effect on soil fertility, so they could be the best covered vegetation to improve soil characteristics related to optimal and sustainable of land management.Keyword : Acacia, albizia, arboretum, cover crop, fern tree, litter, macronutrient, mahogany, rosewood, teak, and vegetation.

Changes in Soil Available Phosphorus, Leaf Phosphorus Content and Yield of Sword Bean (Canavalia ensiformis (L.) DC.) by Application of SP-36 and Phosphate Rock on Acid Upland Soil of East Lampung
Authors: Rivaie Achmad Arivin

A glasshouse trial was performed to determine changes in phosphorus (P) nutrition and the yield of sword bean (Canavalia ensiformis (L.) DC.) following the application of different rates and types of P fertilizer in an acid upland soil of East Lampung. Two different types of P fertilizer, namely SP-36 (total P = 36%) and Phosphate Rock (PR) (total P = 24.3%, particle size distribution = 75% <0.25 mm, 85% < 0.50 mm, 90% < 1.00 mm) were used in the trial. For the treatment, each P fertilizer type consisted of four rates (0, 50, 100 and 150 mg P2O5 kg-1 soil) that were arranged in a Completely Randomized Design with four replications. The results showed that the application of P fertilizers had significant effects on soil pH, soil plant-available P, the potential-P (HCl 25%), leaf N and P concentrations, the yield of sword bean. Increased rates of both forms of P fertilizer increased the soil pH values. As the soil used had low pH and very high exchangeable Al, hence, this result is most probably related to the addition of Ca2+ to the soil solution that resulted from the P fertiliser applied (liming effect), either from SP-36 (monocalcium phosphate) or PR (flour apatite). There was no difference in soil available P concentration due to the different in P fertilizer types, indicating that 4 months after the fertilizer application, the relatively insoluble Phosphate Rock had the same P solubility with SP-36. Increased rates of both forms of P fertilizer increased the sword bean yield. For the application of 0 kg P2O5 ha-1, although sword bean crops had pods, but, they did not give any seed. Whereas, at the addition of P fertilizer at the rate of 50, 100, and 150 kg P2O5 ha-1 for both P fertilizer types, the crops were able to give the seeds in the pods. [How to Cite: Achmad AR. 2015.

The objective of this study was to evaluate the variations of twelve chemical elements (Ni, Fe, Co, Mg, Mn, Al, Si, Zn, Ti, P, Ca and Cr) in laterite soil profiles from Wantulasi area in South East Sulawesi Province of Indonesia. Eighty four (84) samples of three profiles (i.e. each profile consists of eight samples) had been used to study their variations in soil using  the X-Ray Fluorescence (XRF). Results analysis of the chemical elements content in three profile using XRF indicated that there were good correlationsbetween the chemical elements in the soil profile with the significant correlations were found in Ni and Fe, Ni and Si, Ti and P, Fe and Al, and Co and Mn, respectively. On the other hand,the results of study showed that the variations of the chemical elements could be related to the enrichment and translocation of the elements  in soil profile and also their possibilities to be related with a given chemical elements in soil profile. Therefore, we suggest that the observed patterns in chemical elements with a good correlation in laterite profile can be used as proxies to integrate the evaluation of the chemical and physical weathering process based on the elements characteristics in soil profiles.
