Eriani K, Tifani PL, Said S. 2017. Fertilization and development of mice (Mus musculus) embryo in vitro after supplementing the extract of Pandanus conoideus. Nusantara Bioscience 9: 202-208. An extract of red fruit (ERF/Pandanus conoideus Lam.) contains beta-carotene and alpha-tocopherol, i.e. antioxidant compounds group which can stop the formation of free radicals during in vitro fertilization. Reactive oxygen species (ROS) is a free radical which resulted in an oxygen derivate. This research aimed to determine the effect of ERF supplementation on fertilization rate and embryo in vitro development of mice. The study used Completely Randomized Design (CRD) with three group of treatments (ERF dosage supplement: 0 mL, 0.05 mL, and 0.1 mL) and three replications. Each dosage was added to five mice in 7 days. In total, 45 samples were used. Research procedure included extraction of P. conoideus Lam, treatment on the sample, superovulation, preparation of sperm, oocyte collection, in vitro fertilization, and in vitro culture. Parameters observed were the quality of oocyte, the fertilization rate of mice and the development stage of in vitro pre-implantation mice embryo. Acquired data analyzed quantitatively using One Way ANAVA and Duncanâ€™s Multiple Range Test (DMRT) at 5% significance level. The result showed that all treatments did not affect significantly (p>0.05) on the quality of oocyte, in vitro fertilization of oocyte and in vitro early development of embryo. Suggested for further research about the improvement technique of in vitro fertilization and early embryo development.

Clinical Immunohistochemistry (IHC) laboratories face unique challenges in performing accurate and reproducible immunostains. Among these challenges is the use of homemade controls derived from pathological discard samples. Such positive controls have an unknown number of analyte molecules per cell (epitope density). It is unclear how the lack of defined analyte concentrations affects performance of the control. To address this question, we prepared positive IHC controls ( IHControls) for human epidermal growth factor receptor type II (HER-2), estrogen receptor (ER), or progesterone receptor (PR) with well-defined, homogeneous, and reproducible analyte concentrations. Using the IHControls, we examined the effect of analyte concentration on IHC control sensitivity. IHControls and conventional tissue controls were evaluated in a series of simulated primary antibody reagent degradation experiments. The data demonstrate that the ability of a positive IHC control to reveal reagent degradation depends on (1) the analyte concentration in the control and (2) where that concentration falls on the immunostain’s analytic response curve. The most sensitive positive IHC controls have analyte concentrations within or close to the immunostain’s concentration-dependent response range. Strongly staining positive controls having analyte concentrations on the analytic response curve plateau are less sensitive. These findings emphasize the importance of selecting positive IHC controls that are of intermediate (rather than strong) stain intensity.
Teaching of National Programme of Health Development to Undergraduates

Published: July 2017

The practice of community medicine is the delivery of comprehensive health care by a health team trained in curative and preventive medicine to a defined population based on their needs and economy. For some time it has been realized that the integration of curative and preventive services is a well recognized national need. Only such a unification could effectively deliver comprehensive health care to the family which is the ultimate recipient of community care. The success in the application of the health care depends mainly on the training and attitude of the future doctors who are willing to work in the rural areas. It is therefore the responsibility of the medical school to train community oriented doctors, and such a training requires the provision of community projects in which students of the Medical School can participate.

Authors: Kustiman T.S. , Abdulkadir J. , Alisjahbana A.
Published: July 2017

A case of paroxysmal supraventricular tachycardia with Wolff-Parkinson-White syndrome in an Indonesian neonate born in the Departement of Obstetrics, Dr. Hasan Sadikin General Hospital, Bandung, is reported. Tachycardia in the neonate was first noted at the age of 6 days, but the heart rate gradually decreased in 8 hours after oxygen was administered. Electrocardiographic examination revealed a Wolff-Parkinson-White syndrome. A second attack of tachycardia occurred at the age of 2 months and the infant was immediately hospitalized and treated with lanoxin. Serial electrocardiographic examination still revealed the same syndrome. The management and prognosis of supraventricular tachycardia in the neonate is also discussed.

Published: July 2017

The definite diagnosis of cardiac disease in infants and children usuallycannot be made on the clinical evidence alone; in most instances supportingexaminations are required. lt is understandable, therefore, that non-cardiologists might suggest that normal subjects are thought to have cardiac problems; the reverse is also true: infants and children with cardiac disease may be ignored. This study aimed to examine the clinical and laboratory findings of normal infants and children who were initially suspected to have cardiac disease. Of 3601 patients referred to our OPD of the Division of Cardiology, Department of Child Health, Medical School, University of Indonesia, from January 1983 to December 1992; in 1782 patient (49.5%) no cardiovascular problems were detected. Most of them (66.2%) were of the age of less than 1 month. Most of the referring physicians (66.3%) were general practitioners. The referring diagnoses were congenital heart disease (286), cardiomegaly (197), rheumatic fever or rheumatic heart disease (110), and syndromes with cardiac involvement (104). The diagnoses were based on dyspnea, cyanosis on crying, chest pain, joint pains, and easy fatiguability. Murmurs found on examination were systolic in 355 patients (19. 9%), and continuous in 6 patients (0,33%). No diastolic murmurs were noted. The final diagnoses were normal (including innocent murmurs and sinus arrhythmias) in 85.8%, mild cardiomegaly in 10.4%., breath holding spells in 2.0%, sinus tachycardia in 0.9%, polyarthritis in 0.2% and other in 0.7% of all cases. More practice in cardiac physical examination is needed for medical students to reduce the unnecessary referrals.
Structure and Filling Characteristics of Paleokarst Reservoirs in the Northern Tarim Basin, Revealed by Outcrop, Core and Borehole Images

Published: July 2017

The Ordovician paleokarst reservoirs in the Tahe oilfield, with burial depths of over 5300 m, experienced multiple phases of geologic processes and exhibit strong heterogeneity. Core testing can be used to analyse the characteristics of typical points at the centimetre scale, and seismic datasets can reveal the macroscopic outlines of reservoirs at the >10-m scale. However, neither method can identify caves, cave fills and fractures at the meter scale. Guided by outcrop investigations and calibrations based on core sample observations, this paper describes the interpretation of high longitudinal resolution borehole images, the identification of the characteristics of caves, cave fills (sedimentary, breccia and chemical fills) and fractures in single wells, and the identification of structures and fill characteristics at the meter scale in the strongly heterogeneous paleokarst reservoirs. The paleogeomorphology, a major controlling factor in the distribution of paleokarst reservoirs, was also analysed. The results show that one well can penetrate multiple cave layers of various sizes and that the caves are filled with multiple types of fill. The paleogeomorphology can be divided into highlands, slopes and depressions, which controlled the structure and fill characteristics of the paleokarst reservoirs. The results of this study can provide fundamental meter-scale datasets for interpreting detailed geologic features of deeply buried paleocaves, can be used to connect core- and seismic-scale interpretations, and can provide support for the recognition and development of these strongly heterogeneous reservoirs.

Published: July 2017

The article describes how the Structure-from-Motion (SfM) method can be used to calculate the volume of anthropogenic microtopography. In the proposed workflow, data is obtained using mass-market devices such as a compact camera (Canon G9) and a smartphone (iPhone5). The volume is computed using free open source software (VisualSFMv0.5.23, CMPMVSv0.6.0., MeshLab) on a PCclass computer. The input data is acquired from video frames. To verify the method laboratory tests on the embankment of a known volume has been carried out. Models of the test embankment were built using two independent measurements made with those two devices. No significant differences were found between the models in a comparative analysis. The volumes of the models differed from the actual volume just by 0.7‰ and 2‰. After a successful laboratory verification, field measurements were carried out in the same way. While building the model from the data acquired with a smartphone, it was observed that a series of frames, approximately 14% of all the frames, was rejected. The missing frames caused the point cloud to be less dense in the place where they had been rejected. This affected the model’s volume differed from the volume acquired with a camera by 7%. In order to improve the homogeneity, the frame extraction frequency was increased in the place where frames have been previously missing. A uniform model was thereby obtained with point cloud density evenly distributed. There was a 1.5% difference between the embankment’s volume and the volume calculated from the camera-recorded video. The presented method permits the number of input frames to be increased and the model’s accuracy to be enhanced without making an additional measurement, which may not be possible in the case of temporary features.
Deities in Trajan’s and Marcus Aurelius’ Column
Authors: Kovács Péter
Published: July 2017

In his paper the author deals with the deities depicted on Trajan’s and Marcus Aurelius’ Column with a special regard to the cult of Danuvius/Danube and the winged and bearded god of the rain miracle. The cult of Danuvius is rarely attested epigraphically (and not before the 2nd century AD) and it must be connected to Trajan’s campaign against the Dacians. The rain god is iconographically unique but a figure of a river god among the Dionysiac relief panels of the theatre in Perge dated to Marcus Aurelius’ reign can be its first parallel.
A kromograninok, szekretograninok élettani, kórélettani és klinikai szerepéről
Authors: Jakab Lajos
Published: July 2017

Abstract:

This paper investigates the fundamental knowledge, build-up, as well as essential structural and important features of the big family of chromogranins/secretogranins. Previously the different properties and the slightly diverging funcional relations of the two family members were in focus. Later on, it has been discovered that they are essentially two similar compounds with identical structures and functions, and they are chemically, biochemically related. From details discovered so far we can tell that they are long polypeptid chains formed from amino acids. Based on insights gained until now we can also state that these compounds are formed in Ca++ containing environments with acidic pH. Among the compounds there are several molecules which have characteristic oligosacharid groups. This is especially interesting because oligosacharid chains with sialic acid in terminal position play an important role in the recognising and connectional processes. The chromogranins/secretogranins are mostly formed in neuroendocrine cells, but are also capable of building up in any cell type in the organism during pathological processes. Intracellular biogenesis takes place in the dense endoplasmatic reticulum across the mitochondrium, developing biogenetic granulums, followed by the stimulus-motivated secretum (exocytosis). The next stage of the molecular development is the specific break-up of the long polypeptid chains into shorter fragments. These fragments have individual effects. Some important clinical (diagnostic, prognostic) significance and connections are also touched upon in this paper, however, the cardiovascular, immunological systems and the tumors are mostly in focus. There are more immunological, cardiovascular and tumoral data. It is stated that as these molecules are in close connection with all of the organisms and systems of the body, a new chief organisator system has been identified. This chief organisator is closely connected with the central nervous system. Orv Hetil. 2017; 158(28): 1092–1099.

Published: July 2017

Kuantitas produksi udang tambak Indonesia meningkat signifikan dalam dua dekade terakhir, dari 97,2 ribu ton tahun 1989 menjadi 352 ribu ton tahun 2010, dengan puncaknya 409 ribu ton pada tahun 2008. Studi ini bertujuan untuk menganalisis kinerja produktivitas tambak udang dan mengetahui faktor-faktor yang mempengaruhi TFP menggunakan pendekatan angka Indeks Tornqvist Theil. Hasil studi menunjukkan bahwa pertumbuhan udang tambak Indonesia periode 1989-2008 lebih karena pertumbuhan input/faktor produksi bukan karena pertumbuhan TFP. TFP berfluktuasi disebabkan belum berhasil diatasinya permasalahan penyakit. Hasil konfirmasi pada tingkat lapang menggunakan data primer dari 163 petak tambak menunjukkan bahwa serangan penyakit berpengaruh negatif dan signifikan terhadap TFP. Intensifikasi, benur bersertifkat, dan lamanya pendidikan berkorelasi positif, akan tetapi kondisi riil Indonesia berbeda yaitu mayoritas tambak dikelola secara non intensif. Studi ini juga menunjukkan bahwa luas pengusahaan dan sistem kerjasama antara pembudidaya dengan lembaga pemasaran lainnya berpengaruh negatif terhadap TFP. Terkait dengan hal itu, pemerintah perlu memprioritaskan meningkatkan produktivitas dengan mengatasi serangan penyakit melalui penambahan anggaran riset bidang penyakit, penyediaan benur bermutu, peningkatan sumber daya manusia (SDM). Selain itu, diperlukan regulasi dalam hal pengaturan pola tanam dengan penggantian species yang dapat memutus rantai penyakit. Disamping itu, direkomendasikan agar mengurangi padat penebaran. Tittle: Productivity Performance and Factors Influencing to the Total Factor Productivity (TFP) of Indonesia Shrimp Cultured.Production of Indonesian shrimp cultured has experienced a remendeous growth during the last two decades with its peak performance at 409 metric tons in the year of 2008. The objective of this research was to analyze productivity performance of Indonesian shrimp cultured using the Tornqvist Theil Index and its determinants. Results showed that source of growth was mainly due to input gowth. TFP fluctuations were mainly because of disease outbreaks. Using field data comprises a total of 163 ponds confirm that disease outbreaks plays an important role in lowering TFP. Intensification, fry certification, and education halved a positive correlation with TFP. However, the Indonesian shrimp farmers in majority cultured the shrimps using traditional system. On the other hand, cooperation between farmers and other marketing institution and total pond area show a negative effects on achieving higher TFP. Therefore, the government could improve farmed shrimp productivity through increasing research budget on diseases, improving seed quality and human resources. The government should also put a priority regulation on changing cropping system accompanied by changing shrimp species cultured so that carrier agents of diseases can be broken. Apart from these, lowering stocking density was also suggested.

This article was migrated. The article was marked as recommended. IntroductionAfter graduating from medical school, all UK based doctors enter the Foundation Programme. There is on-going evidence, both anecdotally and published, that final year medical students continue to feel unprepared about starting work. We thus designed a one-day course aiming to improve these students' preparedness and anxiety levels.MethodsPre-course material was provided to the students with information on the skills that were going to be explored in the course. After an initial introduction, there was an interactive demonstration to refresh the students' knowledge on assessment of an unwell patient using the recognised ABCDE approach- Airway; Breathing; Circulation; Disability; Exposure . Thereafter, the students were split into 10 groups of 3 and 4 and rotated around 10 different stations. Each station was 40 minutes long and breaks were interspersed amongst the teaching to ensure that concentration was maintained. The emphasis was on near-peer teaching with guidance from a recently qualified doctor.Feedback was requested immediately post-course and three months afterwards.Results and FeedbackThe immediate feedback was very positive with the overall quality rated at 3.93/4.Regarding the 3 month feedback, there was an average reduction in anxiety levels by 18.3% (p<0.0001) and improvement in perceived preparedness levels by 24.7% (p<0.0001).All students agreed that the course will help them in preparing to become a foundation doctor and that similar courses should be offered to all final year students.ConclusionsPractical courses focusing on preparedness can provide a unique opportunity for collaborative training by universities and foundation trusts. These courses are well evaluated and are perceived to improve anxiety and preparedness levels.

Medical stratification in Vietnam
Authors: Lincoln Martha
Published: July 2017

Market transition in Vietnam is known to have fueled health disparities, but racialized and nationality-linked aspects of the country’s medical stratification have received less attention, despite the growing presence of foreigners using the health system. Field experiences reveal the country’s increasing health and medical inequity – legible in the social, linguistic, economic, and physical distinctions between public health stations staffed by government employees and the private clinics serving mostly expatriates. Ethnographic interviews and experiences of receiving care in both public and private facilities inform my argument that the privatization of Vietnam’s health sector produces racialized, classed, and citizenship-linked forms of medical profit, privilege, segregation, and risk – trends visible both in recent debates over US health policy and recent episodes of pandemic disease outbreak.

Published: July 2017

Background: Idiopathic congenital talipes equinovarus (club foot) is a complex deformity that is difficult to correct. The goal of treatment is to reduce or eliminate its four components so that the patient has a functional foot and leads a normal life.Methods: Study have treated 20 patients with 32 idiopathic clubfoot deformities using Ponseti method. The severity was assessed by modified pirani scoring.Results: The mean number of casts that were applied to obtain correction was 7.02 (range four to nine casts). Tenotomy was done in 30 feet. Thirty feet had good results. One patient developed recurrence of the deformity due to non-compliance of the use of orthrotics.Conclusions: The Ponseti method is a safe and effective treatment for congenital idiopathic clubfoot and radically decreases the need for corrective surgery. Non-compliance with orthotics main factor causing failure of the technique.
On New Classes of Sequence Spaces Inclusion Equations Involving the Sets C0, C, lP, (1 ≤ P ≤ ∞), W0 and W∞
Authors: Malafosse Bruno de
Published: July 2017

Given any sequence a = (an)n≥1 of positive real numbers and any set E of complex sequences, we write Ea for the set of all sequences y = (yn)n≥1 such that y/a = (yn/an)n≥1 ∈ E; in particular, ca denotes the set of all sequences y such that y/a converges. Let Φ = {c0, c, l∞, lp, w0, w∞},(p≥1).. In this paper we apply a result stated in [9] and we deal with the class of (SSIE) of the form F ⊂ Ea+F'x where F∈{c0,lp, w0, w∞} and E, F' ∈ Φ. We then obtain the solvability of the corresponding (SSIE) in the particular case when a = (rn)n and we deal with the case when F = F'. Finally we solve the equation Er + (lp)x = lp with E = c0, c, s1, or lp (p≥1). These results extend those stated in [10].

In the present investigation we introduce two subclasses ΝΣδ,μ [η, α, λ] and ΝΣδ,μ (η, β, λ) of the function class Σ of bi-univalent functions defined in the open unit disk. These subclasses are defined by using the Al-Oboudi differential operator, which is the generalized Salagean's differential operator. Also we find estimates on initial coeffcients |a2| and |a3| for the functions in these subclasses and consider some related subclasses in connection with these subclasses.
Oxidation Catalysis in Clean Technologies for Fine Chemicals
Authors: Albonetti S. , Dal Pozzo L. , Trifirò F.
Published: July 2017

The role of heterogeneous catalysis for the production of fine chemicals is reviewed with particular interest for the oxidation in a wide range of aspects of this kind of processes: reaction of oxygen insertion, oxidative dehydrogenation and nitrogen insertion (with ammonia and oxygen). In this review are examined the main processes industrially applied and the best research perspectives in the field of heterogeneous oxidation catalysis for the synthesis of fine chemicals. It is an important point of view in relation with the typical parameters of this field of industrial chemistry and in relation with the driving force of environmental friendly technologies (the line guides of green chemistry) to substitute traditional processes. It is examined either the possibility of the use of gas phases, that is better on an economical and plant point of view, with molecular oxygen, nitrous oxide (it is a very specific oxidant, and it is active in mild conditions) and with the technique of short bed reactor to minimise the effects of the consecutive oxidation reaction particularly on aromatic side chains. Or the use of liquid phases, very useful to work in mild conditions with not stable reagents, with hydrogen peroxide and other alternative oxidants such as regenerable organic hydroperoxides. In the liquid phase reactions it is posed a particular interest in the oxidations carried out with the use of metal doped zeolites, with special attention to tianiasilica catalysts such as TS-1 with the new developments of hydrogen peroxide in situ generation; and heteropoly compounds.
Effects of an Erbium:Yttrium‐Aluminum‐Garnet Laser and Ultrasonic Scaler on Titanium Dioxide‐Coated Titanium Surfaces Contaminated With Subgingival Plaque: An In Vitro Study to Assess Post‐Treatment Biocompatibility With Osteogenic Cells
Authors: Giannelli Marco , Bani Daniele , Tani Alessia , Materassi Fabrizio , Chellini Flaminia , Sassoli Chiara
Published: July 2017

Background: Effects of conventional ultrasonic scaler versus an erbium:yttrium‐aluminum‐garnet (Er:YAG) laser on titanium surfaces contaminated with subgingival plaque from patients with peri‐implantitis are evaluated in terms of: 1) plaque and biocorroded titanium oxide coating removal; 2) surface change induction; and 3) residual biocompatibility toward osteoblasts.

Methods: Subgingival plaque‐coated titanium disks with a moderately rough surface were fixed with ethanol and treated with an ultrasonic scaler (metal tip) or Er:YAG laser (20.3 or 38.2 J/cm2) in non‐contact mode. Fluorescent detection of residual plaque was performed. Disk surface morphology was evaluated by scanning electron microscopy. Viability, attachment, proliferation, and differentiation of Saos‐2 osteoblasts on new and treated disks were assayed by propidium iodide/DNA stain assay and confocal microscopic analysis of cytoskeleton, Ki67, expression of osteopontin and alkaline phosphatase, and formation of mineralized nodules.

Results: Both methods resulted in effective debridement of treated surfaces, the plaque area being reduced to 11.7% with the ultrasonic scaler and ≤0.03% with the Er:YAG laser (38.2 J/cm2). Ultrasound‐treated disks showed marked surface changes, incomplete removal of the titanium dioxide (TiO2) layer, and scanty plaque aggregates, whereas the Er:YAG laser (38.2 J/cm2) completely stripped away the plaque and TiO2 layer, leaving a micropitted surface. Both treatments maintained a good biocompatibility of surfaces to Saos‐2 osteoblasts. Air‐water cooling kept disk temperature below the critical threshold of 47°C.

Conclusion: This study shows that an ultrasonic scaler with metal tip is less efficient than high‐energy Er:YAG irradiation to remove the plaque and TiO2 layer on anodized disks, although both procedures appear capable of restoring an adequate osseoconductivity of treated surfaces.

M�todo: trata-se de uma revis�o integrativa, baseada nas fontes de dados U.S. National Library of Medicine - NCBI (PUBMED), Biblioteca Virtual em Sa�de (BVS), Literatura Latino-americana em Ci�ncias da Sa�de (LILACS), Scientific Electronic Library Online (SCIELO), Medical Literature Analysis and Retrieval System Online (MEDLINE) e Base de Dados em Enfermagem (BDENF), no per�odo de agosto de 2015 a junho de 2016. A partir dos crit�rios de inclus�o e exclus�o, foram selecionados 11 artigos. Resultados: o contexto social e racial em que os indiv�duos com DF est�o inseridos propicia condi��es socioecon�micas e educacionais desfavor�veis; aliados a esses problemas surgem as complica��es da doen�a como a �lcera de perna que influencia negativamente na vida desses pacientes e geram limita��es f�sicas e laborais. Conclus�o: esta revis�o forneceu um panorama de como o contexto social impacta na vida desses pacientes, assim, julga-se necess�rio um delineamento de a��es e iniciativas de pol�ticas p�blicas de sa�de com recorte racial no intuito de promover sa�de e assegurar a equidade, um dos princ�pios do Sistema �nico de Sa�de.
Professores como pesquisadores e a colaboração entre pares: pesquisa, informação e conhecimento no contexto escolar
Authors: Blank Cintia Kath , Silva João Alberto da
Published: July 2017

Este trabalho se propôs a compreender, na perspectiva do letramento informacional, a atividade da pesquisa escolar desenvolvida pelos professores para sua atuação e atualização profissional. Para o desenvolvimento deste estudo participaram sete docentes dos anos iniciais de duas escolas de ensino fundamental da rede municipal de uma cidade do interior do Rio Grande do Sul, integrantes do Programa Observatório Nacional da Educação – CAPES. Em relação à abordagem metodológica, o delineamento se sustenta na Investigação-ação escolar com a utilização de técnicas de Grupo focal; Planejamento cooperativo e a observação, os quais foram posteriormente analisados com auxílio do aporte teórico-metodológico da Análise de Conteúdo. Os dados analisados apontam que são praticadas buscas e não propriamente pesquisas, já que o foco na prática está na localização de informações e não na construção de conhecimentos. Nas pesquisas desenvolvidas pelos professores, a atenção está na aplicabilidade das informações coletadas em suas turmas e, para isso, recorrem a colegas de profissão e blogs de outros professores. O compartilhamento de informações e a divulgação de dados das pesquisas aparecem frequentemente praticados pelos docentes e a principal dificuldade citada por eles é a problemática da cultura escolar com o trabalho de pesquisa. Assim, a pesquisa escolar, na perspectiva do letramento informacional, mostrou que, embora as intenções sejam condizentes com uma visão construtivista, na prática, este fato não se concretiza.
Seleção do conhecimento como operação antagônica
Authors: Le Ravallec Carmen Teresa Gabriel , Rocha Ana Angelita da
Published: July 2017

O presente artigo busca rever a trajetória de Michael f. d. Young (1971; 2000; 2008; 2010; 2011, 2014) para discutir a significação da seleção do conhecimento escolar. Tal proposta tensiona o debate do conhecimento escolar à luz da teoria política, a partir da discussão de antagonismo empreendida por Ernesto Laclau e seus interlocutores (2000; 2005). Com essa tessitura teórica, o artigo defende a relação entre o conhecimento escolar e uma abordagem da teoria política que valorizar a função epistemológica da escola, em tempos de reformas curriculares em escala nacional.
Mostrar o moderno. Viver o possível representações de educação em romances modernistas paulistas
Authors: Konopczyk Vanessa
Published: July 2017

A pesquisa em andamento identifica como são representados os não escolarizados, os escolarizados e a escola, em obras consagradas da literatura paulista do período modernista, a fim de se compreender as relações sociais que são travadas a partir da representação que os autores fazem da docência e dos letrados quanto das pessoas não escolarizadas pela forma tradicional, procurando identificar a forma como se costuram essas relações, muitas vezes permeadas de preconceitos, vez que são representações tecidas por pessoas de sucesso escolar comprovado e posicionadas fora do campo educacional. As análises serão realizadas mediante leitura do conjunto documental escolhido, que se pauta a partir de três frentes: obras em prosa exclusivamente paulistas, de autores consagrados pela participação na Semana de Arte Moderna e sua filiação partidária.  Após a leitura identificar-se-ão e extrair-se-ão os dados para sua comparação com os objetivos propostos, para fins de comprovação de indícios de rupturas e permanências de práticas sociais sobre os assuntos abordados. A partir de então será avaliado o cumprimento dos objetivos da pesquisa, a fim de encontrar a fundamentação e consistência necessárias para validar os vestígios percebidos nas obras analisadas.
A interface entre a família e o direito ao ensino bilíngue para sujeitos surdos: rompendo oposições binárias
Authors: Witkoski Sílvia Andreis
Published: July 2017

O presente artigo busca problematizar a interface entre a família e o acesso real ao ensino bilíngue, desvelando as intrínsecas relações existentes entre as possibilidades dos sujeitos surdos usufruírem deste direito, previsto no Decreto nº 5.626/2005. Tal direito, que pressupõe o uso da Língua Brasileira de Sinais como primeira língua, e da Língua Portuguesa, como segunda, antecede a entrada daqueles na escola, devendo ser promovido no ambiente familiar, desde a descoberta da surdez. A maioria das famílias, no entanto, nega o mesmo, na medida em que opta pelo caminho da normalização de seus filhos. Para romper este ciclo de negação do direito ao bilinguismo, considera-se fulcral problematizar o âmago que envolve as questões, umbilicalmente articuladas, entre identidade e diferença, revisitando os pilares que constroem os binarismos pelos quais o ouvinte é perspectivado como “normal” e o sujeito surdo, como “anormal”, rumo à desnaturalização da “norma”.
A mathematical tool kit for generative justice

Published: July 2017

Como a matemática pode melhor contribuir para a justiça social e a sustentabilidade? A justiça distributiva aborda a pobreza e os problemas relacionados de cima para baixo: movendo o valor extraído da propriedade privada para a propriedade estatal. Mas, a história do socialismo burocrático, da poluição na URSS à escassez de alimentos na Venezuela, mostra tantos problemas quanto o capitalismo. A justiça generativa, ao contrário, funciona de baixo para cima: substitui a extração de valor e a alienação pela circulação de valores. Esses ciclos geradores incluem os trabalhos não alienados, como, por exemplo, os espaços de produção e os códigos abertos; valores ecológicos não alienados como a agricultura orgânica e valores expressivos não alienados como a diversidade sexual, as artes liberadas e outras liberdades polissêmicas. Este ensaio revisará 3 aspectos das etnociências (etnomatemática, etnocomputação e disciplinas relacionadas) em relação à justiça generativa. No caso dos sistemas de conhecimento indígena, há um perigo de alienação do valor à medida que os conceitos são traduzidos em modelos e, posteriormente, abstraídos em currículos de sala de aula. No caso dos sistemas de conhecimentos vernaculares, a colonização por interesses comerciais já ocorreu, e o desafio é desenvolver uma alternativa descolonizada. Finalmente, no caso das relações entre a escola e a comunidade, um ciclo generativo completo pode incorporar fluxos de valores econômico, de saúde e ambientais, alavancando essas abordagens generativas CTEM (Ciências, Tecnologias, Engenharia e Matemáticas). Este ensaio fornecerá, ambos, a teoria e alguns resultados iniciais dessa abordagem generativa CTEM para um mundo mais justo e sustentável.

Introduction: Helminth infection has a profound effect on the immune system. However, the precise nature of the immune changes that are elicited by helminth infection have not been sufficiently characterized. Furthermore, the reversibility of these changes after treatment has not been documented sufficiently. We studied the immune profiles of Ethiopian immigrants to Israel at baseline, that is on arrival and at one-year follow-up and compared individuals who received antihelminthic treatment during the study period with those who missed the treatment.Methods: A longitudinal follow up study involving different groups of subjects was conducted. Baseline data was recorded from the newly arrived Ethiopian immigrants for a series of peripheral blood tests, including: IgE and Eosinophil levels, T-cell populations, T-cell receptor phenotypes, and cytokine measurement. These tests were all repeated after a 1-year interval. Results were compared between the newly arrived Ethiopian immigrants (NEW-Eth-Il), long term Ethiopian immigrants (LT-Eth-Il), and non Ethiopian Israeli controls (NON-Imm-Il). Results: Of the 184 individuals, 111 were NEW-Eth-Il, who had a high prevalence of helminth infection, the immunological changes were elevated IgE levels and eosinophil counts, decreased CD4/CD8 ratio, increased proportion of HLA-DR+CD3+, HLA-DR+CD4+ and HLA-DR+CD8+ cells, decreased proportion of CD45RA+CD4+ (naive) and CD28+CD8+ cells, increased proportion of CD45RO+CD4+ (memory) cells, and increased secretion of IL-4 and IL-5 (Th2 type cytokines). In the 42 LT-Eth-Il participants, who all had negative tests for helminth infection, we did not observe these immune changes and their immune profile did not differ markedly from that of the NON-Imm-Il controls. The follow-up immune profiles of 33 NEW-Eth-Il who received succesful antihelminth treatment, showed a significant normalization in the above-mentioned variables that was not observed in the 19 NEW-Eth-Il who missed and did not receive the antihelminth treatment. Conclusions: These findings demonstrate that helminth infection is associated with profound immune changes that are normalized within a short time after helminth eradication. They also strengthen the hypothesis that effective antihelminth interventions, in areas endemic for intestinal helminths, may have an impact on AIDS and tuberculosis epidemics.
Methods of ammonia removal in anaerobic digestion: a review
Authors: Krakat Niclas , Demirel Burak , Anjum Reshma , Dietz Donna
Published: July 2017

The anaerobic digestion of substrates with high ammonia content has always been a bottleneck in the methanisation process of biomasses. Since microbial communities in anaerobic digesters are sensitive to free ammonia at certain conditions, the digestion of nitrogen-rich substrates such as livestock wastes may result in inhibition/toxicity eventually leading to process failures, unless appropriate engineering precautions are taken. There are many different options reported in literature to remove ammonia from anaerobic digesters to achieve a safe and stable process so that along with high methane yields, a good quality of effluents can also be obtained. Conventional techniques to remove ammonia include physical/chemical methods, immobilization and adaptation of microorganisms, while novel methods include ultrasonication, microwave, hollow fiber membranes and microbial fuel cell applications. This paper discusses conventional and novel methods of ammonia removal from anaerobic digesters using nitrogen-rich substrates, with particular focus on recent literature available about this topic.
