PRELIMINARY STUDY ON SEPARATION OF RARE EARTH METALS FROM LEACH SOLUTION OF DISCARDED FLUORESCENT POWDER BY SOLVENT EXTRACTION
Authors: Quang Nguyen Duc 
Published: August 2018

Discarded fluorescent lamps were considered as hazardous waste in Vietnam (code is 160106). However, its composition contained valuable rare earth metals, which can be recycled and recovered by leaching and solvent extraction processes. The present study sought to define the conditions of separation for rare earth elementals (REEs) from acid leach solution by solvent extraction using PC88A. The acid leach solution was obtained from leaching of fluorescent powder. Efficiencies on REEs extractions as functions of pH levels, extractant concentration, O/A ratio, metal concentration were investigated. For pH values greater than 0.0 and less than 1.0, the orders of the yields extraction were determined: yttrium > terbium > europium > aluminum and calcium. The best separation circuit included four-stage counter current extraction for yttrium separation with 20 %v/v PC88A in kerosene (O/A = 1/1, room temperature, 20 min of contact, pH of 0.38) and stripping step with 3 M HCl acid (O/A = 1/1, room temperature, 30 min of contact). After yttrium separation, the leach solution was extracted at pH of 0.98 in the same other conditions with two-stage counter current extraction to recover terbium and europium group. The final recovery from leach liquor was higher than 98 % and the grade of the final product was 94.2 % (for yttrium) and 93.8 % (for terbium and europium group).

Published: August 2018

A study on the levels of indoor air pollutants in Ha Noi was conducted. Three offices in Ha Noi were selected for this purpose. Selected indoor air pollutants including SO2, NO2 and respirable particulate matter (PM10) were monitored in the wet and dry seasons of 2015. Air conditioners were turned on for the whole time, while air purifiers were turned on for haft of the time in each sampling site. An hourly measurement of outdoor levels was also conducted before indoor measurement. Levels of outdoor PM10 varied in the range of 13.4-106.0 µg/m3. The level of indoor PM10 varied in the range of 3.5-25.1 µg/m3. The average levels of indoor PM10 were lower than that of outdoor one in all cases. High time resolution data showed that indoor PM10 levels temporarily increased sharply by activities (walking and room sweeping) and high frequency of opening the doors. Concentrations of outdoor/indoor SO2 varied in the range of < 0.4-34.5 /< 0.4-47.1 ppb. Concentrations of outdoor/indoor NO2 varied in the range of 4.3-33.4/3.3-27.8 ppb.

Authors: Ra'afat Jwan 
Published: August 2018

Power distribution network consists of a group of radial feeders which can be connected together by several tie-switches and tie-lines. The power loss reduction in the network is a major concern of electric distribution utilities. Among conventional methods, optimal reconfiguration and capacitor placement are two effective methods which can be applied on the network. In this paper a feeder reconfiguration algorithm is build and present for the purpose of power loss reduction in distribution systems. The methodology developed combine optimization technique. The network reconfiguration problem is formulated as single objective optimization problem with equality and inequality constraints. The proposed solution to this problem is based on a general combinatorial optimization algorithm known as genetic algorithm, and the load flow equations in distribution system. The GA optimizes the system-switching pattern for losses reduction. Decides the system topology, and considered taken the size and location of capacitor placement in the radial distribution networks. The two selection method used in genetic algorithm, first method roulette wheel selection and second method tournament selection. Tests show the different in execution time of the program to arrive the best fitness function. The proposed algorithm has been implemented in technical MATLAB package and tested for practical network (48-bus) which is taken from the distribution system of Palestine Street in Baghdad city. Tests show that GA is suitable algorithm as optimization technique, high accuracy, and avoid local minimum by searching in several regions to arrive to the global optimum solution. Thus, the outcome of the study shows an efficient technique to solve the problem of network reconfiguration for loss reduction in the distribution power system.

In Sulaimani Governorate, Kurdistan Region, Iraq (KRI), the total concentration of eleven (11) transitional heavy metals were examined by inductively coupled plasma-atomic emission spectroscopy (ICP-AES) technique in water samples at 8 sites ( S1 to S8) along Qalyasan Stream and Tanjaro River; also S9 was included in Darbandikhan Lake, S9 is a site located after the confluence of polluted Tanjaro River with Darbandikhan Lake water bodies by about 9 km. Water samples were taken on five dates (D1, D2, D3, D4, and D5) from March 2015 till July 2015 at each site of the total nine (9) selected sites along the water sources. Because those water sources are used as a direct sink for the untreated domestic and industrial wastewater effluents and they are in the meanwhile used as a main sources for multi human uses such as; drinking, irrigation purpose and industrial activities. Therefore, the objectives of this study were; evaluation the pollution status of the 11 transitional heavy metals by multivariate data analysis, the study also aimed to define the most polluted sites along the water sources during the studied period. In the present study the results showed that the overall mean concentrations of the studied transitional metals illustrated the following abundance decreasing trend; Fe (6874.30) ˃ Mn (378.98) ˃ Cr (114.44) ˃ Ni (77.63) ˃ Zn (66.71) ˃ V (21.10) ˃ Cu (19.47) µg L-1. Moreover, the concentrations were generally exceeded the criteria of WHO drinking water quality in some observations for those metals that have a defined guideline values by WHO. Additionally, S4 and S5 in D5 of sampling date had particularly the maximum levels for the upper and lower limit concentrations of the studied transitional metals. Consequently, S4 and S5 could be regarded as hot-spot sites or contaminated sites. PCA results indicated a total variance of 82.34 % and 11.61 % among the studied transitional metals and sites respectively. On the other hand, the dendrogram plot classified the nine sites of the studied surface water into three major groups at a significant dissimilarity percent of about 48%. Furthermore, S1 and S9 revealed the highest similarity, in contrast to that, S1 showed the highest dissimilarity with S5.

POLÍTICAS CURRICULARES INTERSETORIAIS ENTRE EDUCAÇÃO, CULTURA, CIÊNCIAS E SAÚDE: EXPERIÊNCIAS DE INVESTIGAÇÃO-AÇÃO-PARTICIPAÇÃO EM ÁREAS DE EXCLUSÃO SOCIAL NO RIO DE JANEIRO / BRASIL
Authors: Figueiredo Gustavo Oliveira , Vermelho Sonia Cristina 
Published: August 2018

Este artigo discute questões referentes à exclusão social no Brasil e as ações intersetoriais, com foco no processo social de construção da juventude e algumas estratégias de articulação entre educação, saúde e cultura numa perspectiva de promoção do desenvolvimento por meio do fortalecimento das redes de interação social e resiliência. Para tanto, apresenta o processo e os resultados de duas pesquisas baseadas no método da Investigação-Ação-Participativa com a comunidade de uma área de favela na cidade do Rio de Janeiro a partir de ações articuladas de pesquisa e extensão. Como resultados, podemos considerar que as duas experiências apontam positivamente como alternativas para lidar com a exclusão social da juventude, contudo as Políticas públicas Intersetoriais entre Educação, Cultura e Saúde não alcançaram todavia uma articulação capaz de fortalecer essas práticas. Ainda encontramos dificuldades, por exemplo, em integrar as atividades e ações dos profissionais da saúde com atividades e ações dos profissionais da educação, apesar da existência do Programa Saúde na Escola. No nível do território, a dificuldade de entendimento da dinâmica dessas duas áreas – em termos teóricos e práticos - emergiu de maneira crítica. São agendas distanciadas como se aquelas instituições de saúde e de educação não estivessem falando e tratando das mesmas pessoas, do mesmo lugar – a favela – e possivelmente, dos mesmos problemas.

João Alexandre Barbosa se rend compte que l’Histoire Littéraire de José Veríssimo reflet bien l’image du critique du XVIIIème: “un Janus à double face”. À partir de cette affirmation, le présent article donne place à la discussion autour de la notion de double face et de Janus. A fin de l’accomplir, ce texte se rapporte aux notions de colonisateur/colonisé ; dominateur/dominé ; orientalisme/occidentalisme, i.e., les oppositions disons classiques, qui ont nourri tant de discussions et impasses. Ici elles sont confrontés et discutés à partir des notions d’expérience de Walter Benjamin, d’étique et celle de casi-cause d’après Gilles Deleuze, la notion d’éfabulation de Sperber, et tout simplement celle de causalité.

Authors: Hazim Hazim 
Published: August 2018

A prevention of corruption in Indonesia through structural approach has been examined by many scholars. The gap is, there is not found a study related to this issue focusing on cultural approach. For this reason, this study is concentrated on the public participation in order to prevent the corruption which focuses on the Urban Poverty Projects (PNPM Mandiri Perkotaan) in Sidoarjo, East Java, as a case study. The research questions are: a) to what extend the community base participant impacts the reduce corruptions?; b) what are the modes of public participation in order to prevent the corruptions?. The aim of this study investigates the mode of community participations in order to minimize the corruption. A descriptive qualitative approach was used to collect the data which used three main methods: a) observation concentrated at two sub-districts, Taman and Sidoarjo; b) interview conducted for getting valuable information from the program executors and beneficiaries of “PNPM Mandiri Perkotaan” as well; c) a study of documents related to the program such as the standart operational procedures (SOPs) as well as proposal and report documents. Some theoretical framewoks of participations have been used to analyse the data. The results of this study can be seen that there are three stages of public participation in order to prevent the corruption: the first is the plan stage. Generally, public still need to be forced to participate at this step. However public have showed significant participations through thought and physical participation with skills. The second is the implementation stage. Public have been able to do self-mobilization participation including physical, psychological participation and participation with skills at this step. Moreover, they also have contributed significantly through financial participation instead of getting income from their involments. However, in the last step called monitoring and evaluation, they generally need to be encouraged by external factors to participate in this stage. Regularly meeting is a part of their participation in order to evaluate their projects.

Improving Nutritive Value of Native Warm‐Season Grasses with the Plant Growth Regulator Trinexapac‐Ethyl
Authors: Tilhou Neal W. , Nave Renata L. G. 
Published: August 2018

Core Ideas
Gibberellin inhibitors may decrease stem growth, improving late fall forage nutritive value during late summer and fall.
Examining the short‐ and long‐term impacts of suppressed stem growth or altered tiller number could result in improved forage nutritive traits.
Warm‐season grasses are characterized by high forage mass but low nutritive value, especially when mature.
Livestock producers in the southeastern United States utilize native warm‐season grasses (NWSG), however, the best management practice to not harvest during late‐summer and fall results in large quantities of low quality forage. Gibberellin inhibitors can alter plant regrowth and forage value. This study assessed the impact of trinexapac‐ethyl [TE; ethyl 4‐(cyclopropyl‐hydroxy‐methylene)‐3,5‐dioxo‐cyclohexane‐1‐carboxylate] on fall NWSG forage. Application of TE occurred in late July at four levels (0, 0.3, 0.6, and 1.2 kg a.i. ha−1) to switchgrass (SG; Panicum virgatum L.) and a mixed sward (BBIG) of big bluestem (Andropogon gerardii Vitman) and indiangrass (Sorghastrum nutans L.) during 2016 and 2017. Forage mass (FM) and nutritive value [crude protein (CP), neutral detergent fiber (NDF), in vitro true dry matter digestibility (IVTDMD)] were evaluated monthly. Application reduced fall FM (SG: 37%; BBIG: 42%). Switchgrass nutritive value did respond to TE application. Application of TE reduced BBIG NDF overall, but strong annual variation occurred due to a drought (2016). Analyzed separately, 2017 treated BBIG samples (1.2 kg a.i. ha−1) exhibited altered FM (−57%), CP (up to 54%), NDF (−9.2%), and IVTDMD (11%). Further analysis provided tentative evidence that TE improved leaf nutritive value and increased leaf proportion, although overall leaf yield was not improved. Overall, TE improved BBIG nutritive value but at a substantial FM loss. Since poor nutritive content forage has negligible value regardless of quantity, growth regulators could improve outcomes of fall NWSG management by adding value to an unutilized resource.
