Failed intentions? Meeting the water needs of people living with HIV in South Africa
Authors: Mary Galvin  , Linah N Masombuka
Published: May 2020

Researchers, activists, practitioners and policy-makers have grappled with the challenge of providing people living with HIV (PLHIV) with an adequate amount of safe water. Comprising 13% of the overall population of South Africa in 2018, 7.52 million PLHIV need water for drinking and taking medication; preparing food; and personal hygiene and cleaning to minimise infections. This article examines the responses of the different stakeholders to this challenge and their impact on the water and health policy process. It finds that activists were able to emphasise the dimensions of the challenge; practitioners worked to implement provision more effectively within existing policy frameworks; and a range of stakeholders made a thoughtful and promising policy proposal for direct action, which the Department of Water and Sanitation ultimately failed to embrace. This article is based on an extensive review of academic research and publications by development agencies on HIV and water as well as engagement with policies and documents in the South African water sector related to water services delivery for PLHIV. While the widespread provision of antiretrovirals from 2004 has changed the context, the above findings are significant in understanding and reviewing the impact of various stakeholders on the water and health policy process. They raise questions regarding the effectiveness of NGO advocacy, the means of delivering improved services to specific populations, and the ability of a range of stakeholders to inform the policy approaches of government departments.
Evaluation of bio-coagulants for colour removal from dye synthetic wastewater: characterization, adsorption kinetics, and modelling approach
Authors: IA Obiora-Okafo  , OD Onukwuli  , NC Eli-Chukwu
Published: May 2020

Dye usage for industrial applications has been on the increase and these activities generate large amounts of dye-constituted wastewater that should be treated before environmental discharge or reuse. Various studies have shown the application of natural organic polymer (NOP) coagulants in dye removal from industrial wastewater. In this research, the coagulation performances of Vigna unguiculata (VU) and Telfairia occidentalis (TO) for colour removal from crystal Ponceau 6R dye synthetic wastewater was studied. The proximate compositions, structure, and surface morphologies of the coagulants were investigated using standard methods, i.e. Fourier-Transform infrared (FTIR) spectroscopy, and scanning electron microscopy (SEM). Colour removal was evaluated through the time-dependent decrease in particle concentration and thus growth of flocs. Effects of the process parameters, including pH, coagulant dosage, dye concentration (DC), settling time, and temperature were preliminarily tested and the best range experimentally determined. The optimal operating conditions established were pH 2, 800 mg∙L−1 coagulant dosage, 100 mg∙L−1 dye concentration, 300 min, and 303 K. The order of greatest removal was VUC > TOC with optimum efficiency of 93.5% and 90.7%, respectively. The values of K and α obtained for VUC and TOC were 8.09 x 10−4 L∙mg−1∙min−1, 1.7 and 9.89 x 10-4 L∙mg−1∙min−1, 1.6, respectively. Coagulation time, Tag, calculated and deduced from the particle distribution plot, showed a rapid coagulation process. Coagulation-adsorption kinetics indicated agreement with the pseudo-second-order model deducing that chemisorption is the rate-controlling step. It further indicates that particle adsorption on the polymer surfaces occurred mostly as a mono-molecular layer and according to the chemisorption mechanism. Cross-validation showed good prediction of the experimental data. The selected coagulants have the potential for application as efficient coagulants while also showing significant adsorption characteristics. The application of kinetics and modelling in separation processes involving particle transfer is especially required in wastewater treatment.
Jasper Johns' Flag: Beyond Realism and Abstraction
Authors: KEKİ Başak
Published: May 2020

Jasper Johns is one of the most provocative American artists of the twentieth century who has shaped the perception of art and has influenced generations of artists. This paper examines one of his most important works, Flag (1955), regarding it as a work defying easy categorizations as either a realist or an abstract work. Without being identified as either kind, it nevertheless displays certain traits of both. As for its suggestion of realism, the work comes up as a response to its political, cultural and artistic context, challenging Cold War aesthetics; albeit in a mocking manner. Its ridicule is evident in its allusion to the concept of ideology via its ‘kitschy’ subject matter whilst its delicately painted surface exhibits brushstrokes reminiscent of abstract expressionism. Yet the work also confronts presumptions of abstract expressionists by drawing attention to their implicit conventionalism despite their claims for authenticity and uniqueness. It will be argued that by calling the notion of identity in question, the work suspends and surpasses neat categories and sparks even further controversy by hinting at postmodern art and evoking ready-mades simultaneously.

Published: May 2020

Context: teaching mathematics to visually impaired students has been challenging teachers in classrooms. Thus, it is important to use manipulative resources for the teaching process. Objective: to evaluate the use of manipulative didactic material for teaching concepts related to the treatment of information for students with visual impairments. Design: applied nature and qualitative approach. Environment and participants: held at a special education school in a countryside municipality in the state of Paraná. The participants were two visually impaired students and a mathematics teacher specialized in the area. Data collection and analysis: semi-structured interview, pre-test and post-test composed of five questions elaborated based on the contents proposed by the National Curriculum Parameters - PCN, and recordings of the classes taught by the responsible teacher. The data collected were examined through the analysis of the conversation, theoretically based on Piotr Yakovlevich Galperin's assumptions on the formation of mental action through steps. Results: revealed that the material developed for this study is a mediating tool in the process of forming mathematical concepts by the participating students, showing the importance of using differentiated resources that allow visual impaired students to access and appropriate knowledge taught at school. Conclusions: based on the appropriation of visually impaired students on how to deal with the material used in the study, we suggest to apply the material to EJA classes; inclusive classes; students with intellectual disabilities and/or disorders such as dyscalculia.

Authors: Rios Navarro Patricia , Pariona Marcos , Urquiaga Calderón Juan Antonio , Méndez Silva Francisco J.
Published: May 2020

Con el objetivo de determinar las características clínicas y epidemiológicas de los pacientes con infarto de miocardio agudo (IMA), se realizó un estudio descriptivo en 175 pacientes de un hospital peruano de referencia. La edad promedio de los pacientes fue de 68,7 años y el 74,8% fueron de sexo masculino. La principal estrategia de reperfusión utilizada fue la angioplastia coronaria transluminal percutánea + stent, aunque su uso primario resultó ser bajo; además, el porcentaje de revascularización quirúrgica fue alto. Casi el 60% de los pacientes tuvo una estancia hospitalaria mayor a siete días. La mortalidad intrahospitalaria fue de 3,4%, siendo el shock cardiogénico la causa más frecuente de muerte. Se concluye que el IMA afecta principalmente a varones mayores de 60 años y que la principal estrategia de reperfusión es la angioplastia, además, los tiempos para la realización de la reperfusión son mayores a lo recomendado con porcentajes altos de revascularización quirúrgica.

Necesidad de revisar las intervenciones sanitarias promovidas por el estado para mujeres en Perú
Authors: Romero-Albino Zoila Olga , Domínguez-Samamés Rafael Omar , Ortiz-Arica Maritza , Cuba-Fuentes María Sofía
Published: May 2020

Se describen las principales intervenciones sanitarias de promoción de salud y de prevención de enfermedades que se deben realizar en las mujeres en el sistema sanitario peruano. Se realizó una revisión de documentos técnicos normativos y de las recomendaciones de las principales organizaciones para prevención a nivel mundial. Dentro de las actividades de prevención se incluyeron la actividad física, alimentación saludable, consejería antitabaco e inmunizaciones. Además, se detallaron los principales tamizajes a realizar en las mujeres, tales como depresión, violencia, riesgo cardiovascular, citología de cuello uterino, mamografía, cáncer de colon; y dentro del espectro de prevención cuaternaria, se detallaron intervenciones que no han demostrado evidencia de beneficio para las mujeres. Las intervenciones sanitarias que se ofrecen desde el sistema sanitario peruano para las mujeres, al estar centradas meramente en aspectos reproductivos, pierden la concepción de integralidad que debe primar para el mantenimiento de la salud. En ese sentido, se propone el desarrollo de estrategias que no solo tengan evidencia, sino que sepan responder a las necesidades de las mujeres en el contexto peruano.

Land of Opportunity: Anti-Black and Settler Logics in the Gentrification of Detroit
Authors: Quizar Jessi
Published: May 2020

It is an increasingly common trope in anti-gentrification activism to claim that gentrification of Black neighborhoods is a form of settler colonialism. Although Native critics have pushed back against these metaphors as abstractions of, and false equivalencies to, the concrete conditions of settler colonialism, gentrifying discourse frequently draws on the language and logic of settler colonialism in narratives about the city of Detroit. In this article, I ask what it means that terms and logic that are being applied to a predominantly Black city were, and are, also used to rationalize and structure theft of land from Native Americans. Proposing that shifting white interests in Black land have led to “borrowing” of longstanding logics used to dispossess Native peoples, I argue that the reiteration of settler-colonial logics in Detroit to explain and justify gentrification manifestly both validates land grabs in the city and further erases the claims of both Black and Indigenous peoples to Detroit.

Published: May 2020

A study was carried out to evaluate the performance of improved varieties of tef and production technologies in Becho district of Oromia, Centeral Ethiopia. Five improved tef varieties along with the local were selected and used as treatments (that is, Dega tef (T1), Guduru (T2), Kena (T3), Kora(T4),Quncho(T5) and Local (T6)) arranged  in a Randomized Complete Block Design (RCBD) with six replications using six farmers’ fields. Yield and yield related parameters were analyzed using SAS statistical software version 9.0. Economic analysis/profitability, preference/acceptability, gender and nutrition and environmental suitability data recording were performed to compare treatments advantages and identify the best performing varietity/ies. All the yield and yield related components were significantly different between the varieties at 5 % probability level %) except for plant height in which there was no significant difference among varieties. Variety Dega tef gave the highest grain yield   with average grain yield of 3610.6kg/ha followed by Quncho and Kora and also had about 40% yield advantage over the local variety with average grain yield of 2577.83kg/ha and had about 116.95%, 110.25% and 90.80 % yield advantage over the national, regional and zonal average yield of tef in 2016/2017 Meher season of CSA data respectively. Based on farmer’s preference analysis variety Dega tef had high acceptability (75%) followed by Quncho (73%) and Kora (70%). Guduru variety has the least in acceptability (21%). As the result from the economic analysis showed that Dega tef variety had the maximum net benefit (79,536.69birr/ha) followed by Quncho (67,106.97birr/ha) and Kora (63,746.96birr/ha). Variety Guduru had the least net benefit result of about 53,648.17birr/ha. Based on the rules of decision making and the integrated scoring set for technology validation, two of the three improved varieties meet the requirements to be recommended. Therefore, we recommend Dega tef, Quncho, and Kora varieties for Becho areas and other areas with similar agro-ecological conditions in the central highlands of Ethiopia.

Published: May 2020

Desde una perspectiva bourdesiana, se analizan las estrategias de acumulación y conversión de distintas formas de capital (cultural, económico, simbólico y social) que los productores de pulque ponen en práctica en los procesos de construcción social de iniciativas de turismo agroalimentario. Se trata de una nueva actividad rural a la que los productores se incorporan con desventajas materiales y culturales respecto a las reglas del campo turístico consensuadas por los actores dominantes. A partir de un enfoque cualitativo y exploratorio, se estudió la Feria del Pulque en Jiquipilco (Estado de México), en la que se identificó que la apropiación turística del patrimonio agroalimentario se consolida por medio de la reproducción continua de normas, valores y estrategias diferenciados entre los agentes que se disputan los beneficios de la actividad turística.
El argumento de la falta de consenso regional en derechos humanos. Divergencia entre el TEDH y la Corte IDH
Authors: Clérico Laura
Published: May 2020

Este trabajo analiza críticamente una constelación argumentativa central en el TEDH que combina inexistencia de consenso europeo con amplio margen de apreciación al Estado. Las complejidades de esta constelación suelen ser opacadas cuando algunos Estados de la región interamericana abogan por su importación. Para ello se propone distinguir diferentes usos del consenso, así como también la función descriptiva y normativa del argumento, y la relación entre la existencia o ausencia del consenso europeo y la determinación del margen de apreciación del Estado. Estas complejidades permiten determinar con precisión la divergencia entre el TEDH y la Corte IDH en el uso de la falta de consenso regional en la constelación de casos referidos a la discriminación por orientación sexual, como así también proponer diversas hipótesis que traten de explorar la divergencia. Todo este camino argumentativo permite seguir sosteniendo la tesis acerca de los perfiles argumentativos divergentes de las cortes regionales que está determinado por sus audiencias: por un lado, el TEDH, como una corte preocupada por los interlocutores, los Estados de la región, frente a, por el otro, la Corte IDH, preocupada por evaluar las razones o sinrazones de las restricciones a los derechos, más allá del (des)agrado de los Estados de la región.

Authors: Lee Ho Min , Kim Jae Ki , Nam Jung Gwon , Lee Tae-Hoon
Published: May 2020

Background and Objectives: Evaluation of Epworth Sleepiness Scale (ESS), Berlin, STOP, and STOP-Bang questionnaire validities for obstructive sleep apnea (OSA) screening among various adult age groups.Materials and Method: Results for each of those questionnaires were compared with diagnostic overnight polysomnography (PSG) data obtained for 396 patients suffering either insomnia, sleep apnea, excessive daytime sleepiness, or chronic snoring who had been divided into three age groups (20-39, 40-59, or ≥60 years). For each questionnaire, the sensitivity, specificity, accuracy, and area under the curve (AUC) were calculated.Results: Among the OSA group [apnea hypopnea index (AHI) cutoff ＞5], Berlin and STOP questionnaire sensitivity and specificity were significantly different among the age groups. Among the moderate-to-severe OSA sub-group (AHI cutoff ＞15), the specificity of Berlin, STOP, and STOP-Bang questionnaire was significantly different among age groups.Conclusion: The Berlin and STOP questionnaires differed with patient age in OSA screening. The ESS questionnaire, by contrast, did not show any age-related differences of sensitivity and specificity in OSA screening or moderate-to-severe OSA screening.
A Case of Transient Visual Disturbance and Ocular Paresis after Endoscopic Sinus Surgery
Authors: Lee Ji Soo , Yang Jeong Hwan , Lee Joong Seob
Published: May 2020

Endoscopic sinus surgery (ESS) is widely used as standard surgical treatment for chronic rhinosinusitis. Orbital complications of varying degrees occurred during ESS have been widely reported. If the orbital symptoms occurred immediately after surgery, ocular damage associated with surgery is suspected if the patient’s preoperative ocular function was patent. If immediate action is not taken, permanent visual loss might develop, so it is very important to diagnose orbital complications and take appropriate action. In our case, there was no definite intraorbital hemorrhage when sudden visual loss was noted. The symptoms were fully recovered without further treatment and it is clinically suspected to be caused by transient ocular muscle toxicity of local anesthetics.

In this study, species distribution model- ling (SDM) was applied to the manage- ment of secondary forests in Benin. This study aims at identifying suitable areas where the use of candidate pioneer spe- cies, such as Lonchocarpus sericeus and Anogeissus leiocarpa, could be targeted to ensure at low cost, currently and  in  the context of global climate change, fast reconstitution of secondary forests and disturbed ecosystems and the recovery  of their biodiversity. Using occurrence records from the Global Biodiversity Infor- mation Facility (GBIF) website and cur- rent environmental data, the factors that affected the distribution of the species were assessed in West Africa. The models developed in MaxEnt and  R  software  for West Africa only, for both species, showed good predictive power with  AUC > 0.80 and AUC ratios well above 1.5. The results were projected in future climate at the horizon 2055, using AfriClim data under rcp4.5 and rcp8.5 and suggested a little reduction in the range of L. seri- ceus and any variation for A. leiocarpa. The potential distribution of the two spe- cies indicated that they could be used for vegetation restoration activities both now and in the mid-21st century. Improve- ment are needed through the use of com- plementary data, the extension to others species and the assessment of uncertain- ties related to these predictions.
RUBBER TREE CLONAL PLANTATIONS: GRAFTED VS SELF-ROOTED PLANT MATERIAL
Authors: Masson Aurélien , Monteuuis Olivier
Published: May 2020

The forest tree species Hevea brasiliensis is extensively planted in the humid tropics to meet the increasing demand for natural rubber. Huge quantities of planting stock are therefore needed. The seed option remains the easiest and cheapest way to establish plantations of rubber trees but those show a great variability for vigor and also for latex yield. The rationale of produ- cing clones for overcoming this variability was already obvious in the early 1910’s but due to the difficulties encountered at that time for rooting shoots, grafting was used as an alternative cloning method. The striking increase in yield noticed from the graft-derived clonal plantations warranted their large scale development. Eventually, the budded clones by virtue of their much higher and uniform produc- tivity supplanted the seedlings in most industrial plantations. However, grafting is also associated with drawbacks and for decades efforts aiming at mass producing selected rubber tree clones on their own roots by rooted cuttings have been pur- sued. However, this approach was pro- gressively abandoned due to disappoin- ting rooting results and, from the 70’s onwards, priority has been given to in vitro methods which were booming during this period. But despite 40 years of heavy investments, industrial H. brasiliensis clones could still not be mass micropro- pagated in vitro efficiently enough to meet the requirements of large scale produc- tion. The situation may change radically soon, however, due to the development of new nursery techniques adapted to the mass clonal production by rooted cuttings of any H. brasiliensis selected genotype. Efforts to improve the techniques as well as the establishment of new field trials are underway in order to determine if self-rooted rubber tree clones are more productive than grafted ones. This old issue is becoming of overriding impor- tance considering the increasing pres- sure on land availability reducing thereby the prospects for expanding rubber tree plantations.

According to environmental predictions, West Africa is becoming vulnerable to the adverse effects of climate change and land use dis- turbance. Herbaceous vegetation is the most sensitive to these effects. To assess the poten- tial of species to cope with these changes, this study investigated the dispersal potential of different herbaceous species. Data on her- baceous plant composition and environmen- tal parameters were collected along climate, land use and habitat gradients in West Afri- can savannah areas, as well as the diaspores of all herbaceous species encountered. Their traits were described in order to document the diversity of diaspore categories in herbaceous savannah vegetation. Based on an occurrence diagram, variations in dissemination patterns within families were identified. The dispersal potential of each species was determined on the basis of their patterns of dispersal. A hie- rarchical classification method was used to establish a dispersal typology, and principal component analysis was applied to identify the environmental conditions that account for their patterns of dispersal. The results show that the diaspores of herbaceous spe- cies can be classified according to fruit type, diaspore type, presence of heterodiaspory, exposure of diaspores, number of seeds per diaspore, diaspore morphology, shape of diaspores and pattern of dispersal. Poaceae, the most abundant family in savannah areas, have six patterns of dispersal. Most species have more than one pattern, and species with high dispersal potential (85.43%) dominate the herbaceous vegetation. Four groups of herbaceous species were identified according to their dispersal patterns. Potentially epizoo- chorous and anemochorous species (39.25% of the flora) were more related to village areas independently of climatic conditions and habi- tat types. Potentially endozoochorous and dysozoochorous species (31.06% of the flora) were more related to fresh and dry habitats in protected areas of the North and South Suda- nian zones. Potentially hydrochorous species (12.63% of the flora) were related to wet habi- tats but were more prominent in the Sahel, and potentially autochorous species (17.06% of the flora) were more related to bowé habi- tats in the southern Sudanian zone. Our study showed that all herbaceous species have good dispersal potential, which might enable them to persist in West African savannahs despite the severe climatic changes predicted.

Scaffolding is one of the important components in the concrete job. Its role of supporting the work of concrete, the structure of scaffold should be taken into account appropriately. Failure in planning of the scaffold will result disturb on a concrete job. Along with the development of the times, the construction services company developed a method in the work of the scaffolding. One example that is replace the scaffolding with steel profiles. The purpose of the advent of modificated steel scaffold is to allow the structure of the scaffold to be able to sustain a larger burden compared with the structure of the scaffolding. Behind the goals to be achieved, there is the risk that may occur. For example, swelling costs resulting from the use of steel profiles for the components of the structure of the scaffold. Therefore, must to be evaluated so as to achieve greater efficiency in terms of steel profile dimensions as well as the cost product of use modificated steel scaffold. Modificated steel scaffold in Tunjungan Plaza 6 projects were used to shore up the structure Transfer Beam named megatruss. From the results of this research obtained efficiency of steel profile dimensions for the scaffold structure. So obtained also the efficiency to cost product the use of scaffolding megatruss is equal of 20,05%.

The high growth of the population in Malang will trigger an increase in the activity of its, resulting in increased traffic. Increased traffic demands will add to traffic congestion problems on roads and intersections. One way of traffic engineering to improve signaled intersection performance is to equip traffic signals with countdown timers. This additional instrument serves to inform the duration of the signal setup time. This study aims to determine the effect of countdown timer use on saturation flow, performance and safety factor signalized intersection in Malang. The paired sample t-teste statistical method is used to see the influence of the countdown timer on saturation flow, and the impact on the performance and safety of the intersection arm. The use of countdown timer can increase the value of saturation flow, so the capacity of the intersection also increased 5-22% with decreasing delay time 5-13 sec/smp. But the less positive impact on the safety factor intersection, because there is an increase in the movement of vehicles before the green time.

Tingginya pertumbuhan jumah penduduk di Kota Malang akan memicu peningkatan aktifitas penduduk sehingga berdampak pada meningkatnya lalu lintas. Peningkatan tuntutan lalu lintas akan menambah masalah kemacetan lalu lintas pada ruas jalan dan simpang. Salah satu cara rekayasa lalu lintas untuk meningkatkan kinerja simpang bersinyal adalah melengkapi sinyal lalu lintas dengan countdown timer. Instrumen tambahan ini berfungsi menginformasikan durasi waktu pengaturan sinyal. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan countdown timer terhadap arus jenuh , kinerja dan faktor keselamatan simpang bersinyal di Kota Malang. Metode statistik paired sample t-teste digunakan untuk melihat pengaruh countdown timer terhadap arus jenuh, dan dampak pada kinerja serta keselamatan lengan simpang. Penggunaan countdown timer mampu meningkatkan nilai arus jenuh, sehingga kapasitas lengan simpang juga mengalami peningkatan 5-22% dengan penurunan waktu tundaan 5-13 detik/smp. Tetapi kurang berdampak positif terhadap faktor keselamatan simpang, karena terjadi peningkatan pergerakan kendaraan sebelum waktu hijau.
