Humanização e docência crítica: a arte como mediação na formação inicial docente / Humanization and critical teaching: art as mediation in initial teacher training
Authors: Venancio Magda Machado Ribeiro , Souza Vera Lucia Trevisan de
Published: June 2018

Este artigo apresenta uma pesquisa de doutoramento de caráter interventivo. Adota-se o aporte teórico-metodológico da psicologia histórico-cultural com o objetivo de investigar se atividades cujas bases incluem a ética e a estética ampliam a visão dos estudantes sobre a dimensão humanizadora da docência e conduzem à docência crítica. Participaram 30 alunas do quinto semestre do curso de Pedagogia em faculdade privada no interior de São Paulo. Recorreu-se às materialidades artísticas mediadoras como instrumento psicológico promotor de reflexões críticas. Os dados foram obtidos em quatro situações interventivas por meio de desenhos e textos produzidos pelas participantes. Registrou-se em Diário de Campo as observações das situações que envolveram o uso das materialidades. A leitura do material e dos Diários de Campo resultou em informações agrupadas em núcleos de significação, possibilitando a aproximação dos sentidos sobre a docência e o trabalho docente, configurados pelas participantes. A pesquisa revelou a prevalência da afetividade no modo de conceber a docência; que a docência ainda é vista como missão, acolhendo a dor e atenuando a exclusão social. Evidenciou a apropriação sem reflexões críticas do discurso oficial da educação para justificar a importância da educação escolar e valorizar a escolha da docência.
Confiança e fracasso na educação: interpelação à pratica docente / Confidence and failure in education: Queries regarding teaching practice
Authors: Silva Ezir George , Röhr Ferdinand
Published: June 2018

A pesquisa inscreve-se nos debates sobre Educação, Formação Humana e Prática Pedagógica. Sua investigação consiste em examinar, segundo o olhar de Otto Friedrich Bollnow, a possível interação entre os fenômenos estáveis e instáveis das estruturas da vida e dos processos educativos, a partir dos pressupostos da Filosofia da Existência e da Filosofia da Esperança. Pretende-se, por um lado, interrogar sobre as especificidades da re/produção do fracasso escolar em uma era de desconfiança e, por outro lado, equacionar as possibilidades de uma pedagogia da esperança. Em termos de problematização, questiona-se: o princípio da continuidade é realmente a pressuposição necessária de toda e qualquer educação? A discussão tem como objetivo investigar a relação entre a Confiança e o Fracasso na Educação e suas interpelações à prática docente, apresentando um diálogo entre as categorias da descontinuidade e da continuidade e suas exigências e implicações para a construção de uma educação esperançosa quando encontra confiança no ser educando, o fulcro de toda prática pedagógica que pretende a humanização dos homens em seus processos formativos. Do ponto de vista metodológico, optou-se pela reflexão hermenêutico-ontológica, por estar voltada para o tratamento interpretativo das informações e contribuições teóricas, à medida que visa desvelar as estruturas do desenvolvimento da formação e estabelecer uma íntima relação entre o educador e o sujeito educando.

Authors: Helard Denny , Indah Shinta , Sari Chintia Maya , Mariesta Hestia
Published: June 2018

The potential of adsorption and regeneration of Indonesian natural pumice to remove nitrate from aqueous solution was studied in multiple adsorption-desorption cycles. Batch experiments were performed to examine the effect of various experimental parameters on the removal of nitrate. The optimum condition of nitrate removal by natural pumice were obtained at 3 of pH solution, 0.3 g/L of adsorbent dose, 30 min of contact time, <63 μm of particle size, and 90 mg/L of nitrate concentration with 54.79% of removal efficiency and 164.37 mg/g of nitrate uptake. The experimental data obtained were fitted with the Freundlich adsorption isotherm within the concentration range studied. Although complete desorption were not achieved, the result confirmed that HCl can be used as desorbing and recovery agent, which be desorbed 10-13% of nitrate ion. The used natural pumice also could be regenerated and reused up to three successive adsorption-desorption cycles. Overall results revealed that the ability of natural pumice to adsorb nitrate will create more interest to develop a new adsorbent from local mineral for pollutant removal from water

A detailed palynological analysis of the Chacoparaná Basin is presented. Thirty-one samples were recovered from boreholes YCF.CO1, YCF.CO2 and YCF.CO3, corresponding to the lower part of the Ordóñez Formation, at the Santiago Temple locality (Córdoba Province, Argentina). Three new species are described: Calamospora fissurata sp. nov., Retusotriletes archangelskyi sp. nov. and Horriditriletes chacoparanensis sp. nov.; Leiotriletes malanzanensis nov. nom., Endosporites menendezi nov. nom., emend. are proposed to replace L. tenuis Azcuy and E. parvus Menéndez; and the following species are proposed as new combinations: Brevitriletes coalescens (Menéndez & Azcuy) nov. comb., Brevitriletes papillatus (Menéndez & Azcuy) nov. comb., B. sparsus (Menéndez & Azcuy) nov. comb., B. delicatus (Menéndez) nov. comb. and Indotriradites malanzanensis (Azcuy) nov. comb. Two different associations were identified and are compared with the known biozones from the same basin and other biostratigraphical schemes for basins from central western Argentina. The palynological assemblage can be referred, in part, to the Potonieisporites–Lundbladispora Biozone (Chacoparaná Basin) and the Raistrickia densa–Convolutispora muriornata Biozone (central western basins of Argentina, latest Serpukhovian–Bashkirian).
Regional Recovery of Gravity Anomaly from the Inversion of Diagonal Components of GOCE Gravitational Tensor: A Case Study in Ethiopia
Authors: Eshagh Mehdi , Gedamu Andenet A. , Bedada Tulu B.
Published: June 2018

The tensor of gravitation is traceless as the gravitational field of the Earth is harmonic outside the Earth’s surface. Therefore, summation of the 2nd-order horizontal derivatives on its diagonal components should be equal to the radial one but with the opposite sign. The gravity field can be recovered locally from either of them, or even their combination. Here, we use the in-orbit diagonal components of the gravitational tensor measured by the gravity field and steady state ocean circulation explorer (GOCE) mission for recovering gravity anomaly with a resolution of 1°×1° at sea level in Ethiopia. In order to solve the system of equations, derived after discretisation of integral equations, the Tikhonov regularisation is applied and the bias of this regularisation is estimated and removed from the estimated gravity anomalies. The errors of the anomalies are estimated and their significance of recovery from these diagonal components is investigated. Statistically, the difference between the recovered anomalies from each scenario is not significant comparing to their errors. However, their joint inversion of the diagonal components improved the solution by about 1 mGal. Furthermore, the inversion processes are better stabilised when using errors of the input data compared with its exclusion, but at the penalty of degradation in accuracy of the estimates.
Biological drilling: Implant site preparation in a conservative manner and obtaining autogenous bone grafts
Authors: Anitua Eduardo
Published: June 2018

Background/Aim: The drilling process for insertion of an implant should be as conservative as possible, as not to damage the future implant bed. If this drilling is conservative additional bone can be obtained to be used afterwards, during the same surgery, as bone graft particulate if needed. The objective of this study was to evaluate the efficiency of a biological low-speed drilling and to analyse the bone obtained in order to ascertain viability and vitality of the contained bone cells. Also, the bone obtained from the low-speed drilling was compared with bone obtained with high speed drilling and irrigation, collected through a filter in aspiration system. Material and Methods: In this pilot study, samples of biological drilling (low speed without irrigation) were collected in five patients undergoing implant surgery. In the same patients a high speed drilling with irrigation was also used. Bone of the drilling was collected through a filter in the aspiration system. Subsequently the samples were analysed by conventional histology and cultivated in order to observe cell growth. Results: The samples of bone obtained by biological drilling showed live cells in the conventional optical microscopy and cell growth after cultivation. The bone obtained with drilling at high revolutions showed no living cells and no cell growth after cultivation. Conclusions: The biological drilling at low speed offered two advantages compared to drilling at high speed with irrigation. The first of these is the perfect control of the drilling depth as the marks of the burs are visible during drilling; the second is possibility of collection of a large number of viable particulate bone grafts without increasing time and complexity of the surgery, which allows immediate augmentation of bone if needed.
The effects of two different preservation methods on morphological characteristics of the alien channel catfish Ictalurus punctatus (Rafinesque, 1818) in European freshwater

Published: June 2018

Different methods used to store specimens, even for short periods, can notably affect morphometric characteristics such as colour, length and shape. As a consequence, in the case of samples that have to be analysed morphometrically, the right preservation method is crucial. In this study, two comparably easy applicable methods, the effects of freezing and moderate cool storage on morphological traits, were studied on specimens of the scaleless North American channel catfish Ictalurus punctatus, an alien species to European freshwaters of increasing concern. Results revealed that freezing, like preservation with alcohol or formalin, affected the generally considered characteristics (colour, standard length, fork length, total length, shape), while cool storage was shown to preserve most traits without notable alteration, an important difference when studying potentially adapting alien species. Implications are discussed.
The role of edaphic, vegetational and spatial factors in structuring soil animal communities in a floodplain forest of the Dnipro river
Authors: Zhukov Oleksandr V. , Kunah Olga M. , Dubinina Yuliya Y. , Novikova Viktoriya O.
Published: June 2018

This paper examines the role of ecological factors, derived from principal component analysis performed on edaphic and vegetational dataset as well as spatial variables, in structuring the soil macrofauna community of the Dnipro floodplain within the ‘Dnipro-Orilsky’ Nature Reserve (Ukraine). The soil macrofauna was defined as invertebrates visible to the naked eye (macroscopic organisms). The test points formed a regular grid with a mesh size of 3 m with 7 × 15 dimensions. Thus, the total test point number was 105. At each point, soil-zoological samples of 0.25 × 0.25 m were taken for quantifying the soil macrofauna. The spatial structure was modeled by a set of independent spatial patterns obtained by means of principal coordinates of neighbor matrices analysis (PCNM-variables). Spatial PCNM-variables explain significantly more variations of the community (19.9%) than edaphic factors (4.1%) and vegetation factors (3.2%). Spatial and combined environmental and spatial effects were divided into three components: broad-scale component was characterized by periodicity of spatial variation with a wavelength of 24.0–44.5 m, medium-scale – 11.1–20 m, fine-scale – 6.6–11.0 m. For a broad-scale component, environmental factors of a vegetational nature are more important, for medium-scale, edaphic factors are more important, for fine-scale, both vegetation and edaphic are important. For litter-dwelling animals, the most characteristic spatial patterns are on the broad and medium-scale levels. For endogeic and anecic animals, the most significant variability is on the fine-scale level.

Authors: Luo D. , Wang J. R. , Fečkan M.
Published: June 2018

In this work, we apply fractional calculus to analyze a class of economic growth modelling (EGM) of the Spanish economy. More precisely, the Grünwald-Letnnikov and Caputo derivatives are used to simulate GDP by replacing the previous integer order derivatives with the help of Matlab, SPSS and R software. As a result, we find that the data raised from the Caputo derivative are better than the data raised from the Grünwald-Letnnikov derivative. We improve the previous result in [12].
Application of Motion Capture Attributes to Individual Identification under Corridor Surveillance
Authors: Mihálik A. , Ďurikovič R. , Sejč M.
Published: June 2018

Accurate and fast identification of a person from a security point of view is a key procedure. The most common technique of person identification uses identity cards. In contrary to the common approach we focus our research on identification based on the body movement such as the gait in this paper. The gait and the posture belong to the unique characteristics of the person that helps us to facilitate the identification. The proposed methodology allows us to incorporate personal characteristics into the access control systems using the color depth camera (RGBD). For the sake of gait analysis, the important task is to recognize the figure and extract the skeleton data from a video recording. Besides the usage of the mathematical statistics methods, we are opting to use computer animation and computer vision methods, which makes the research interdisciplinary. The main novelty of the paper is the definition and extraction of the feature vector from motion capture data, the analysis methodology and finally the selection of few statistically dominant motion attributes for the identification purposes. Besides the development of new approaches in this field, we validate proposed approaches from the perspective of accuracy.

Authors: Kim Soo-Hyeon , Seung Byung-Joon , Cho Seung-Hee , Lim Ha-Young , Park Hee-Myung , Sur Jung-Hyang
Published: June 2018

Introduction

p63 is a homologous molecule of p53 and was recently identified as playing important roles in several key cellular processes, including epithelial development and proliferation. Since then, several studies have demonstrated altered p63 expression in various cancers of epithelial origin. Canine perianal gland tumour is one of the most common skin neoplasms in dogs; however, the molecular characteristics of this tumour remain poorly understood. The objective of the present study was to analyse and compare the expression of p63 in canine perianal gland adenomas and carcinomas.

Material and Methods

Haematoxylin and eosin-stained slides were examined and immunohistochemistry was conducted for a total of 65 samples. Immunohistochemical data for p63 expressions were compared between groups using the Mann-Whitney U test.

Results

The p63 expression level was increased in perianal gland carcinomas compared to that in the adenoma samples (P < 0.0001). The percentage of cells expressing p63 was higher in perianal gland carcinomas than in adenomas, although the intensity of immunostaining did not differ significantly between the two groups.

Conclusion

p63 is a candidate factor contributing to the malignant transformation and progression of canine perianal gland tumours.
Characterization of the Hammamet basin aquifer (North-East of Algeria) through geochemical and geostructural methods and analysis
Authors: Chelih Fatha , Fehdi Chemseddine , Khan Shuhaib
Published: June 2018

Morphostructural, hydrogeological and hydrochemical approaches were applied to Hammamet plain and its surrounding mountains in the eastern part of Algeria to characterize the groundwater system and its potential for exploitation. The Essen and Troubia Mountains form the natural boundaries of Hammamet plain. The objective of this study is to utilize remote sensing techniques combined with structural analysis, hydrogeology and hydrogeochemistry to identify the potential fracture zones for groundwater in the strongly fractured and karstified deep aquifers. The delineated zones of potential groundwater resources are verified by detailed hydrogeological field surveys.

From a hydrogeological point of view, these two mountains, constitute a unit limited by faults oriented ENE-WSW, NNW-SSE and NNE-SSW. Specifically, fractures of the latter two directions influence the compartmentalization and the hydrogeological functioning of this unit. According to the degree of fracturing and/or karstification, two basic types of aquiferous behaviour have been distinguished: fissured aquifer (Essen Mountain and Troubia Mountain), and porous aquifer (Hammamet plain).

The study of the hydrochemical characteristics of groundwater samples shows that the majority of samples are mainly of HCO3− and Ca2+ water type. The ionic speciation and mineral dissolution/precipitation was calculated with the PHREEQC software. The chemical composition of the water is influenced by the dissolution and/or precipitation processes during the water–rock interaction and by the cationic exchange reactions between groundwater and alluvial sediments. The high content of CO2 in the water samples suggests that they circulate in a geochemical open system. The isotopic analysis of some groundwater samples shows a similarity with the meteoric waters, which reflect their short residence time and a low evaporation of the infiltrated water.
Evolution of capture technologies of water in the oases: Moghrar, Tiout and Boussemghoun (Algeria)
Authors: Hadidi Abdelkader , Remini Boualem , Habi Mohamed
Published: June 2018

This article discusses the various water harvesting techniques used in the oases of Boussemghoun, Moghrar and Tiout for more than nine centuries. Several hydrological assessments have been conducted in the three oases since 2002 including surveys and investigations with the local communities. The results obtained showed that after the decrease in discharge of the sources, the population had resources to various ancestral hydraulic infrastructures such as: well, foggara, and small dams (Essad). The water harvesting technique is specific to the region and depends on the hydrogeology and the topography. Traditional low-flow water-saving technologies preserve the environment, modern hydraulic techniques give more water but have a negative impact on the environment. The drying up of springs and lowering of water tables are the result of the population growing and the socio-economic development. They require more and more water. A compromise between traditional and modern techniques (or types of management) can solve this problem.
Hydrological conditions of peatland formation based on a dynamic curve of a biogenic sediments sequence – a new proposal
Authors: Lipka Krzysztof , Zając Ewelina
Published: June 2018

The aim of the study was to propose a so called dynamic curve for identification of hydrological conditions of peatland formation. This method facilitates interpretation of accumulation processes based on sequence of biogenic sediments depending on variable hydrological conditions. Eleven types of hydrological conditions (HC) were distinguished and characterized with reference to ecohydrological interrelations governing the formation of peatlands. Each HC type was associated with specific peat type and species rendered in a classification for Central Europe. When employing a synthetic description of the identified HCs, it is possible to use the dynamic curve to provide a graphical representation of a hydration status for a geological profile and a general interpretation of the course of changes in water conditions during peatland development. The discussed method is somewhat simplified but it can be used for general interpretation of hydrological conditions of peatland development and would not require some highly specialized analyses. Such an approach may prove sufficient, particularly in engineering practice.
Salinity and modelling of the Annaba aquifer system, North-East of Algeria
Authors: Majour Habiba , Hani Azzedine , Djabri Larbi
Published: June 2018

The potentiometer area in the Annaba basin, covering an area of 264 km2, has declined considerably since 1995. The analysis of the chronological hydrographs (1991–2009) of the piezometric observations shows that this decline is related to about twenty years (20 years) drought that began in 1991. To synthesize hydrological data and study regional changes in aquifer interactions caused by changes in discharge, and determine the contamination of aquifers by salty intrusion in coastal areas, and making forecasts by the year 2023, a multi-layered transient model as well as a solute transport model has been developed. The groundwater flow was modelled using the finite difference method with a horizontal dimension of 500 × 500 m for the cells. The model consists of two layers, the first corresponding to the alluvial phreatic aquifer and the second to the deep confined aquifer, and is calibrated against the steady state groundwater heads recorded before 1996. Model verification was done by history matching over the period 1991–2009. Under steady-state conditions, the correspondence between simulated and observed water levels is generally good (average difference of 0.4 m). For the deep aquifer, the simulated time-series hydrographs closely match the recorded hydrographs for most of the observation wells. For the alluvial aquifer, the recorded hydrographs cover only a short time period, but they are reproduced. The model indicates that groundwater pumping induced a decrease in natural discharge, a downward leakage in most of the basin and a continual water-level decline. The model has also been applied to the analysis of recharge impact. Simulating the behaviour of the system over the period 1991–2009 without pumping indicated small changes in hydraulic head.

These results show that the groundwater reservoir has a low recharge, but excellent hydraulic properties. A solute-transport model was used to study aquifer contamination from salty intrusion in coastal sectors; it was extended to the year 2023 by simulating an optimistic hypothesis that maintains present pumping until 2023. The model indicates that the head decrease of the alluvial phreatic and deep confined aquifers will be 4 m and 5 m respectively. The solute concentration in the deep confined aquifer will increase from 1 gꞏdm−3 (prior 2009) to 5 gꞏdm−3 in 2023.
Using DEM and GIS for evaluation of groundwater resources in relation to landforms in the Maharlou-Bakhtegan watershed, Fars province, Iran
Authors: Mokarram Marzieh , Shaygan Mehran , Sathyamoorthy Dinesh
Published: June 2018

The study of groundwater resources in relation to topography is important. Clearly, in different topography, depth of the water level is different. Therefore, the aim of this study is the determination of the relationship between landform classes with compound topographic index (CTI) and depth of the water for the Maharlou-Bakhtegan watershed, Fars Province, Iran. In order to evaluate the depth of the water for the study area, CTI and geomorphology (landforms) were derived from a Shuttle Radar Topography Mission (SRTM) digital elevation model (DEM). The results of landform classes extracted using topographic position index (TPI) showed that the largest landform is open slope, while the smallest are plains. It was found that CTI and depth of the water values are high in plain classes, while they are low in local ridges. High depth of the water were found to be mostly confined to the pit regions in the plain landform, because groundwater recharge occurs in the zones where standing water remains for sufficient long period of time and has favourable condition for recharge.

Iconicity of syntax and narrative in Amerindian prosaic texts
Authors: Volkova Svitlana
Published: June 2018

The notion that the form of a word bears an arbitrary relation to its meaning accounts only partly for the attested relations between form and meaning in the world's languages. Recent research suggests a more textured view of syntactic and narrative structure in Amerindian prosaic texts, in which arbitrariness is complemented by iconicity (aspects of form resemble aspects of meaning) and systematicity (statistical regularities in forms predict function).

Authors: Mazáková J. , Zouhar M. , Sedlák P. , Zusková E. , Ryšánek P. , Hausvater E.
Published: June 2018

A total of 235 Phytophthora infestans isolates were collected from five regions of the Czech Republic during the growing seasons 2012–2014 and 2016 and examined using the in vitro amended agar method for their sensitivity to metalaxyl-M (MFX), propamocarb-HCl (PCH), and dimethomorph (DMM). A majority of the isolates (50%) were sensitive to MFX. Resistant isolates were found in all four years of the survey; they represented 30% of the samples. The EC50 values of PCH in inhibiting mycelial growth of 65% of the overall isolates were higher than 100 μg ml−1, which indicates the occurrence of insensitivity to PCH in the Czech P. infestans populations. DMM was very effective, and the mycelial growth of all isolates tested was completely suppressed at the concentration of 0.1 μg ml−1. Furthermore, the efficacy of 12 plant essential oils was tested against 20 isolates of P. infestans using the in vitro amended agar method. Essential oils of Cymbopogon winterianus, Litsea cubeba, Mentha spicata, Pelargonium graveolens, Syzygium aromaticum, and Thymus vulgaris were observed to have the highest antifungal activity against P. infestans, with minimal inhibitory concentrations less than or equal to 1 μl ml−1.

Published: June 2018

Selected maize hybrids were analyzed according to the in vivo digestibility of the silage. Eight tested hybrids were grown, harvested, and ensiled under identical conditions. The effect of earliness (early maturity group FAO 230–260 vs moderately early maturity group FAO 290–340) significantly (P < 0.05) affected the chemical composition, fermentation quality, and digestibility of neutral and acid detergent fibre. Type of kernel endosperm (dent vs flint) differed by digestibility of nutrients. Digestibility of dry matter, organic matter, and neutral detergent fibre was the highest for silage of the dent hybrid FAO 250 (73.7, 75.7, and 67.6%, respectively) and these digestibility values were significantly (P < 0.05) lower for silage of the dent hybrid FAO 320 (61.1, 63.4, and 51.4%, respectively). It was concluded that the digestibility differs mainly in dent-type hybrids. All correlation coefficients between the digestibility values were significantly (P < 0.05) high.

Authors: Němeček T. , Tůmová E.
Published: June 2018

The aim of this study is to evaluate the effective population size and fertility in the Czech Genetic Resources of nutrias during the last ten years. This study includes three Czech colour types of nutrias: Czech Type of Standard (ST), Moravian Silver (MS), and Prestice Multicolour (PM). The effective population size of ST shows that this colour type is endangered, while MS and PM are critical. The average number of pregnancy was the highest (P ≤ 0.004) in ST (1.7 pregnancy) and the lowest in PM (1.3 pregnancy). ST and MS nutrias had the significantly biggest litter size (P ≤ 0.004). For the number of kits born per female in a year (P < 0.001) the significantly lowest value was in PM (5.1 kits). For weaned kits the highest value (P ≤ 0.006) was in ST (4.8 kits). The results showed that the population size of MS and PM is low and there is a risk of biodiversity loss in these colour types.

Published: June 2018

We evaluated Cu, Fe, Mn, and Zn concentrations in the bone, muscle, testes, intestine, liver, kidneys and tapeworm parasites Hymenolepis diminuta of rats from four groups: 12 animals given zinc lactate (120 mg/rat and week) in feed mixture (M0 group); six animals given zinc lactate (120 mg/rat and week) in feed mixture and infected with tapeworms (MT group); six control animals fed a standard mixture of ST-1 for rats (00 group); and six control animals fed a standard mixture of ST-1 for rats and infected with tapeworms (0T group). The experiment was conducted over a six-week period. In our study, tapeworm presence decreased element concentrations in the majority of rat tissues. Tapeworms accumulated higher levels of zinc and manganese than did the majority of host tissues; however, they accumulated very little iron and copper in comparison to the host tissues. Zinc overdosing increased manganese concentrations in rat tissues; zinc overdosing also seemed to protect the liver from absorption of Fe by tapeworms.

Published: June 2018

The process of European integration required the harmonization of the Polish law with EU legislation and the physical implementation of the new regulations. One of the areas in which these activities were carried out was environmental protection. The aim of the study was to assess the impact of the Europeanisation process on environmental investment, ecology policy and the practice of environmental protection in rural communes using the example of the Wysokie Mazowieckie rural commune. The study have shown that the impact of the EU integration process was significant. This influence can be most clearly observed in the following two areas: the growing importance of environmental protection in commune policy and the acquisition of external financial resources for pro-ecological investments. Thanks to this, it was possible to solve many important environmental problems in the commune, especially regarding water and wastewater management as well as waste management.

There are not easy for new companies to build a reputation or brand image. The company still needs trust first from the community that used their products. Trademark have a very important role, especially in maintaining fair business competition, because the brand can be a differentiating force for one company with another company. The purpose of this study to know the awareness of communities concerning the importance of registering the Trademark based on Law No. 20 of 2016 on Trademark and Geographical Indications. This study uses the method of empirical legal research with sociological jurisprudence approach, as well as data analysis using qualitative analysis. The study shows that the lack of company awareness in understanding the importance of trademark registration, they do not understand the benefits of registering trademark. Communities who set up businesses tend do not registering their trademark, one of the reason is caused by highly cost. As a result, the implementation of the Trademark Law becomes less effective in practice.

Perusahaan yang baru berkembang tidak tidak mudah membangun reputasi atau brand image. Perusahaan masih  membutuhkan   kepercayaan terlebih dahulu  dari masyarakat pengguna mereknya.  Merek memiliki peran yang sangat penting terutama dalam menjaga persaingan usaha yang sehat, karena merek dapat menjadi daya pembeda bagi satu perusahaan dengan perusahaan lain. Tujuan tulisan ini untuk mengetahui kesadaran masyarakat akan pentingnya mendaftarkan merek berdasarkan Undang-Undang Nomor 20 Tahun 2016 tentang Merek Dan Indikasi Geografis. Penulisan ini menggunakan metode penelitian hukum empris dengan pendekatan sociological jurisprudence, serta analisa data menggunakan analisis kualitatif. Hasil penelitian menunjukkan bahwa masih kurangnya/kesadaran masyarakat dalam memahami penting pendaftaran merek, mereka tidak memahami manfaat pendaftaran merek. Masyarakat cenderung mendirikan usaha dengan tidak mendaftarkan mereknya, salah satu faktornya adalah biaya yang sangat mahal, sehingga menyebabkan implementasi ketentuan merek menjadi kurang efektif di dalam prakteknya.

Published: June 2018

Các kết quả nghiên cứu trên thế giới cho thấy nước rỉ rác chưa được xử lý có chứa hàm lượng cao nhiều kim loại nặng có nguy cơ gây ô nhiễm môi trường đất và nước dưới đất. Hầu hết các nghiên cứu đều cho kết quả là đất và nước dưới đất trên khu vực bãi chôn lấp rác thải và lân cận chưa bị ô nhiễm kim loại nặng ở mức lớn hơn qui chuẩn cho phép đối với đất sản xuất nông nghiệp. Tuy nhiên, các nghiên cứu đều cho thấy rác thải và nước rỉ rác có vai trò gây ô nhiễm làm gia tăng hàm lượng kim loại nặng trong đất dựa trên các phân tích đánh giá theo không gian và giá trị hàm lượng kim loại nặng nền trong môi trường. Theo kết quả phân tích các mẫu kim loại nặng trong mẫu đất khoan tại bãi chôn lấp Kiêu Kỵ thì hàm lượng của một số kim loại nặng vượt quá QCVN 03-MT: 2015/BTNMT như As (hàm lượng 28-30g/kg) và Cr 154-294mg/kg) từ 1,5 đến 2 lần. Đặc trưng đường cong phân bố hàm lượng các kim loại nặng trong đất theo độ sâu ở đây thì chiều sâu xâm nhập ô nhiễm khoảng 4-5m. Kết quả nghiên cứu cũng cho thấy mức độ ô nhiễm kim loại nặng gia tăng khi khoảng cách đến bãi chôn lấp rác thải giảm: hàm lượng Cr, Pb và Zn ở khoảng cách 5 m đến mép bãi chôn lấp chỉ bằng khoảng 50% so với tại rìa bãi chôn lấp. Kết quả ban đầu còn cho thấy rằng hàm lượng As nên trong đất tự nhiên ở khu vực lớn hơn giá trị cho phép của QCVN về đất sản xuất nông nghiệp.

The present study was conducted to find out the water requirements and most suitable irrigation frequencies for cowpea (Vigna unguiculata L.) var grown under drip irrigation. The treatments were based on the IW:CPE ratio at different empirical pan factors 0.6 , 0.8, 1.0, 1.,1.4 , and 1.6 Ef (where Ef = IW/CPE). It was observed that the irrigation interval was variable values decreased by increasing Ef value and with the progress of the growing season. The 1.2 and 1.0 IW: CPE treatments with approximately 4 days irrigation interval were achieved the best results. The total amount of applied water during Cowpea growing season was varied between 247.7 and 266.5mm with 254.8mm as a mean. Irrigation treatment with Ef1.2 was superior over the rest of other treatments in fresh seed yield (5.13 ton.hec.-1), crop water productivity (2.14 kg.m-3), biological yield (6.88 ton.hec.-1) , fresh pod yield (7.33 ton.hec.-1), weight of 100 seed (31.28gm), number of seed/pod (9.34) and netting percentage (37.1). The lowest values of the most parameters used in this study were obtained by Ef 0.6 irrigation treatment.

Seven wheat genotypes (Triticum dicoccum) and the local check sham5 were planted all at Al-Ghab and Izra Research centers in The General Commission for Scientific Agricultural Research in Syria during growing season 2010/2011. Yield components (number of total and fertile tillers per plant, number and weight of grains per spike, weight of thousand grain and individual plant grain yield) were studied in two sites in order to predict their effect and to determine their effects on grain yield in order to define selection criteria for grain yield. Results revealed all studied traits except total tillers number were positively correlated with grain yield, and only (fertile tillers number and grain number per spike and grain weight per spike) had a significant regression with grain yield and these traits can explain about (27.6, 67.7, 62.2)% respectively of the variation final grain yield. Results of path analysis indicated that the direct effect of fertile tillers per plant and grain weight per spike on grain yield was positive and high (0.6178, 0.7563) respectively, so that we can depend on them in breeding program as selection criteria to increase grain yield in plant.

O movimento feminista possui dentro de sua história uma série de vertentes que colaboram para o fortalecimento e ampliação de pautas de lutas. Na medida em que cresce, o movimento amplia suas pautas de discussões incluindo novas temáticas que precisam ser debatidas, novas dificuldades a serem superadas. Dessa forma, o presente trabalho tem por objetivo discutir sobre aspectos históricos e teóricos do feminismo. Realizamos uma leitura de três teóricas: Beauvoir, Friedan e Hooks, contextualizando-a com as realidades sociais e políticas do período. No decorrer do trabalho apontamos para o fato de não haver um único feminismo. O feminismo, portanto, é tão plural quanto as mulheres que levantam essa bandeira e está em constante atividade. Para tanto, pautamos nosso trabalho nas propostas de Friedan em A Mistica Feminina (1971), em Feminist theory from margin to center (1984) e Feminism is for everybody: passionate politics (2000), de Hooks) numa tentativa de compreender uma parcela da conjuntura do feminismo.

Infecção hospitalar (IH) ou infecção nosocominal se define como qualquer doença infecciosa contraída após a hospitalização do paciente, mesmo que o indivíduo não tenha apresentado sinais e sintomas antes de seu internamento. Para que o processo infeccioso se instale, o microrganismo depende de uma falha no sistema de defesa do hospedeiro, o qual pode ou não manifestar a patologia. A utilização de desinfetantes com ácido peracético e o hipoclorito de sódio são métodos que conferem maior potencial antimicrobiano. No entanto, diversos microrganismos possuem mecanismos de resistência frente a medidas comumente adotadas para desinfecção. A pesquisa objetivou avaliar a eficácia antimicrobiana de desinfetantes utilizados no setor pediátrico e unidade de terapia intensiva neonatal, além de verificar a presença ou ausência de microrganismos em superfícies inanimadas pertencentes ao local de estudo assim como verificar a qualidade da higienização. Foi realizado o teste de coloração de Gram, catalase e coagulase para identificação morfológica e para a avaliação da eficácia dos produtos foi utilizado o teste de concentração inibitória mínima, onde foram usadas cepas padrões como Staphylococcus epidermidis, Staphylococcus aureus, Streptococcus pneumoniae, Pseudomonas ssp e Eschericia coli. Na avaliação da eficácia somente na cepa referente a Streptococcus pneumoniae obteve Inibição em concentração até 0,3µl (Total). Diante do exposto pode-se concluir que, observou-se uma contaminação de microrganismos bacterianos nos setores de pediatria e UTI neonatal, bem como uma eficácia dos agentes químicos utilizados na higienização dos setores, mas ou mesmo tempo os produtos se comportaram de maneira ineficaz.
Exploring Drugbank in Virtual Reality Chemical Space
Authors: Probst Daniel , Reymond Jean-Louis
Published: June 2018

The recent general availability of low-cost virtual reality headsets, and accompanying 3D engine support, presents an opportunity to bring the concept of chemical space into virtual environments. While virtual reality applications represent a category of widespread tools in other fields, their use in the visualization and exploration of abstract data such as chemical spaces has been experimental. In our previous work we established the concept of interactive 2D maps of chemical spaces, followed by interactive web-based 3D visualizations, culminating in the interactive web-based 3D visualization of extremely large chemical spaces. Virtual reality chemical spaces are a natural extension of these concepts. As 2D and 3D embeddings, and projections of high-dimensional chemical fingerprint spaces were shown to be valuable tools in chemical space visualization and exploration, existing pipelines of data mining and preparation can be extended to be used in virtual reality applications. Here we present an application based on the Unity engine and the virtual reality toolkit (VRTK), allowing for the interactive exploration of chemical space populated by Drugbank compounds in virtual reality. The source code of the application as well as the most recent build are available on GitHub.

Pedagogia moderna no Brasil: primeiras discussões e experiências práticas (final do século XIX – início do XX)
Authors: Ghizoni Teive Gladys Mary
Published: June 2018

O presente artigo trata das primeiras discussões e experiências práticas acerca da pedagogia moderna no Brasil. A partir da apresentação de seus dois principais pilares – o método de ensino intuitivo e as chamadas “lições de coisas” –, analisa os debates sobre a supremacia dessa pedagogia em relação à tradicional e as polêmicas sobre o caráter que o novo método e as lições de coisas deveriam assumir na reestruturação do ensino público primário brasileiro. Neste sentido, são destacadas as reformas da instrução pública empreendidas no município da Corte, no Rio de Janeiro, em 1879, e no estado de São Paulo, em 1891, e o papel decisivo que o manual Primeiras lições de coisas, de autoria de Norman Calkins, teve como guia prático no preparo das lições intuitivas dos professores das escolas primárias e dos alunos das escolas normais, até a década de 1920.
