(Title: Wagyu Reception As A Shoku Bunka in Indonesia) Wagyu is popular for its quality and its delicious taste. Nowadays wagyu has became a trademark for the best quality of beef. Wagyu is originally from Japan that now has spread to all over the world. 13 years ago, Indonesian government has banned the import of wagyu. But now the ban has been revoked. As a result some of indonesian people are still not familiar with the term of “wagyu”. The purpose of this study are to know whether wagyu has been received as one of Japanese food or not and also the reasons behind it.  This study is done by searching some references from trusted sources to answer those questions. The results of this study are wagyu has been well received by the people of Indonesia. The reasons are wagyu is already certified as halal food by MUI, now that in Indonesia there are many local breedres that produce local wagyu, and also recently there are many Indonesian food recipes that uses wagyu as its main ingredient.
Yerel Özerklik Bağlamında Belediyelerin Denetimi: İtalya ve Türkiye Örneği
Authors: KÜÇÜK Hülya
Published: April 2018

Denetim kavramının, yerel özerklikle ters orantılı olduğu yönünde tartışmalar bulunmaktadır. Yerelyönetimlerin üzerindeki denetim arttıkça yerel özerklik azalmakta, denetim azaldıkça yerel yönetimlerdaha geniş bir özerklikten yararlanmaktadır. Yerel yönetimlerin gerçek anlamda var olabilmesi içinyerel yönetimleri Anayasa ile güvence altına almak ve vesayet denetiminin sınırlarını iyi bir şekildebelirlemek büyük önem taşımaktadır. Yerel yönetimlerin özerk olmaları görevlerini en iyi şekildeyerine getirebilmeleri açısından oldukça önemlidir. Yerel yönetimlerin özerkliği, kanunlarla belirlenensınırlar çerçevesinde, kamu işlerinin önemli bir bölümü kendi sorumlulukları altında ve yerel nüfusunçıkarları doğrultusunda düzenleme ve yönetme hakkı ve imkânı anlamını taşımaktadır. Bu bağlamdayerel yönetimlerin kendi organlarıyla kendileri ile ilgili konularda merkezin baskısı ve yönlendirmesiolmadan kendi imkânlarıyla karar alabilmesi özerklik için önemli bir yere sahiptir. İtalya ve Türkiye’deyerel yönetimler Anayasal olarak güvence altına almakta, merkezi yönetim tarafından yerel yönetimlerüzerinde idari vesayet denetimi uygulanmaktadır.Bu çalışmanın amacı, İtalya’nın merkezi yönetiminin belediye yönetimi üzerindeki denetimiyle, Türkiye’dekibelediyelerin denetimini karşılaştırma yaparak incelemektir. İki ülkenin denetim açısından benzer vefarklı yönleri ele alınarak, Türkiye’deki denetim sistemine ışık tutabilmesi amaçlanmıştır. Çalışmada, yerelözerklik, mali özerklik ve idari vesayet kavramlarına açıklık getirilerek yerel özerklikle denetim arasındakiilişki Avrupa Yerel Yönetimler Özerklik Şartı bağlamında ele alınıp kavramsal çerçeve oluşturulacaktır. İtalyave Türkiye’nin belediye yönetim birimleri ayrıntılı bir şekilde ele alıncaktır. İki ülkenin belediye yönetimlerimerkezi yönetimle olan ilişkisi idari vesayet denetimi üzerinden değerlendirilecektir.Çalışmada elde edilen bulgulardan yola çıkarak, İtalya’nın üniter yapılı bir devlet olmasına rağmenmerkezi yönetimin bölgesel yönetimleri yoğun bir şekilde denetlemediğini söylemek mümkündür.Bölgesel yönetimlerin ise, illeri ve belediyeleri hukuki açıdan denetlediği ve Avrupa Yerel YönetimlerÖzerklik Şartı’nın denetimle ilgili maddesine uygun şekilde düzenlemeler yaptığı görülmektedir.Türkiye de üniter yapıya sahip bir ülkedir ve AYYÖŞ’ün denetimle ilgili maddesine çekince koymuştur.2000’li yıllarda yaptığı reformlarla yerel yönetimlerin özerkliklerini genişlettiği görülse de yapılanson düzenlemeyle merkeziyetçi yapısını korumaya devam ettiği görülmektedir. İtalya ve Türkiye’ninAvrupa Yerel Yönetimler Özerklik Şartı bağlamında denetime olan yaklaşımları incelendiğindeTürkiye’nin uyguladığı denetimin İtalya’ya kıyasla Şarta pek de uygun olduğunu söylemek mümkündeğildir.

Variable Surface Temperature Distribution as a Criticality Indicator of the Self-Heating Effect in Composites
Authors: Katunin A.
Published: April 2018

Since self-heating effect may significantly intensify structural degradation, it is essential to investigate its criticality, i.e. the temperature value at which fatigue fracture is initiated. In this paper, a new and sensitive criticality indicator based on evaluation of evolution of surface temperature distribution was proposed and experimentally validated. It was shown that comparing to other measurement techniques the presented approach allows for precise evaluation of the critical value of the self-heating temperature. The properly determined critical value may be helpful both during design and operation of elements made of polymers and polymeric composite.

Published: April 2018

Mn, as Fe, Zn, Cu and Ni is a heavy metal and also a necessary element all the living organisms. Excessive Mn nutrition causes a strong oxidative stress. The aim of the studies was to determination the effect of Se treatment (as sodium selenite Na2O4Se3) to alleviate the Mn stress of plants. Because of its sensitivity to oxidative stress induced by excessive concentrations of Mn a model plant was lettuce (Lactuca sativa L. ‘Sunny’). The studies were conducted in a controlled environment growth room in stable climate conditions: 16 h photoperiod; temperature light/dark 18.0 ±0.5°C/16.0 ±0.5°C; relative humidity 70-80%; quantum flux density 195-205 μmol m−2 s−1. Plants were grown hydroponically in nutrient solution characterized by excessive Mn content (19.2 mg dm−3) and different contents of Se (control; 0.77, 1.05, 1.33 mg dm−3). In all the combination were also tested different foliar sprays (distilled water and a 0.005% Se solution). Plants grown under conditions described above take up and transported Se from nutrient solutions into their leaves with a significant reduction of Mn concentration and changes in the plant nutrient status. With the increase in the concentrations of Se clearly narrowed quantitative relations in the leaves between this element and micro-metallic. Increasing Se levels in nutrient solution has a positive influence on the growth of plants, but Se foliar treatment generally decreases plant yield. The study shown that Se application may lead to alleviation of Mn stress of plants, with simultaneous reduce in Mn concentration in leaves - which may be of practical importance also in the cultivation of more economically important species.
Justifying Water Rights in Nigeria: Fiction or Achievable Panacea?
Authors: Okukpon Irekpitan , Anozie Ijeoma
Published: April 2018

Nigeria, like other countries in the world, competes for available water resources due to the increasing demands for the resource as a result of agricultural and other industrial activities. Nigeria’s current National Water Policy 2017 is vague regarding the enforcement of the right to water, with an absence of institutions to actualise same. The provisions under chapter II of the Constitution of the Federal Republic of Nigeria 1999 does not provide a justiciable cushion for the actualisation of this right. This paper examines the reality of the right to water in Nigeria, using South African policy as a model. It interrogates the feasibility of existing policy on water in Nigeria against the backdrop of the South African right to water, which is justiciable and hailed as one of the most proactive in water legislation around the world. The paper concludes with recommendations on the justifications for the right to water in Nigeria, advocating systematic engagements with government and community stakeholders as a key driver towards achieving sustainability and entrenchment of the right to water in Nigeria.

Dispersion characteristics of hydroxyl and carboxyl-functionalized multi-walled carbon nanotubes in polyester nanocomposites
Authors: Islam Muhammad Remanul , Beg Md. Dalour H.
Published: April 2018

Multi-walled carbon nanotube (MWCNT) reinforced polyester-based composites were prepared by mixed blending in a solvent. Orthophthalic unsaturated polyester was blended individually with different types of non-functionalized and functionalized MWCNTs. Two types of functional groups: hydroxyl (-OH) and carboxyl (-COOH) were introduced with MWCNTs for the nanocomposites. The mechanical properties of the composites, like tensile, three-point bending and impact energy were evaluated. Fourier transform infrared spectroscopy was used for the functional group analysis. The dispersion characteristics of the samples were observed by transmission electron microscopy and field-emission electron microscopy. In addition, the thermal decomposition and melting behavior of the samples was assessed by differential scanning calorimetry and thermogravimetric analysis. The properties were varied due to the variation of the functional groups. The result analysis showed that the entangled agglomerations of hydroxyl-functionalized MWCNTs were destroyed to relatively smaller clusters. The hydroxyl-functionalized MWCNTs were more effective for homogeneous dispersion and contributed for better mechanical properties of the composites, compared to non-functionalized and carboxyl group-functionalized MWCNTs.
Cyber-Aggression as an Example of Dysfunctional Behaviour of the Young Generation in the Globalized World
Authors: Prymak Tomasz , Sosnowski Tomasz
Published: April 2018

The objective of this paper is to try to identify the specificity and frequency of cyber-agression as a form of problem behaviour characteristic for the contemporary youth known as Generation Y. Analysis of the results of research conducted among schoolchildren aged 15–16 indicates that cyber-agression is a common phenomenon in the group. It raises the need for reconstruction and re-evaluation of practices and standards developed to date and implemented to address the problematic behaviour of young people through the global network. In the paper, proposals for solutions in this area are presented, which can be used to create future prevention programs aimed at constructive online behaviour and foster rational choice-making regarding the use of the Internet and modern media.
Acetylation-Dependent Recruitment of the FACT Complex and Its Role in Regulating Pol II Occupancy Genome-Wide in Saccharomyces cerevisiae

Published: April 2018

Histone chaperones, chromatin remodelers, and histone modifying complexes play a critical role in alleviating the nucleosomal barrier for DNA-dependent processes. Here, we have examined the role of two highly conserved yeast (Saccharomyces cerevisiae) histone chaperones, facilitates chromatin transcription (FACT) and Spt6, in regulating transcription. We show that the H3 tail contributes to the recruitment of FACT to coding sequences in a manner dependent on acetylation. We found that deleting a H3 histone acetyltransferase Gcn5 or mutating lysines on the H3 tail impairs FACT recruitment at ADH1 and ARG1 genes. However, deleting the H4 tail or mutating the H4 lysines failed to dampen FACT occupancy in coding regions. Additionally, we show that FACT depletion reduces RNA polymerase II (Pol II) occupancy genome-wide. Spt6 depletion leads to a reduction in Pol II occupancy toward the 3′-end, in a manner dependent on the gene length. Severe transcription and histone-eviction defects were also observed in a strain that was impaired for Spt6 recruitment (spt6Δ202) and depleted of FACT. Importantly, the severity of the defect strongly correlated with wild-type Pol II occupancies at these genes, indicating critical roles for Spt6 and Spt16 in promoting high-level transcription. Collectively, our results show that both FACT and Spt6 are important for transcription globally and may participate during different stages of transcription.

Published: April 2018

Background: Breast cancer (BC) is the most common cancer malignancy and the important reason for cancer-related mortality in females. The aim of this study was to evaluate the geographical distribution of occurrence and mortality of BC and their association with Human Development Index (HDI) in Europe in 2012.

Methods: This was an ecologic study to evaluate the relation between Age-Standardized Incidence Rate (ASIR) and Age Standardized Mortality Rate (ASMR) of BC with HDI, using data of GLOBOCAN project and the HDI report. Using SPSS18 statistical analysis software the data of the study was analyzed; the significance level of the tests was considered as P 0.05.

Results: The highest ASIR of BC was observed in Belgium, Denmark, the Netherlands and the highest ASMR was found in the FYR Macedonia, Serbia, Belgium, respectively. A positive correlation was found between the ASIR of BC and HDI (r= 0.611, p≤ 0.001), life expectancy in birth (r= 0.706, p≤0.001), average education years (r=0.038, p=0.815) and gross national income per capita (r= 0.719, p≤0.001). Moreover, there was negative correlation between the ASMR of BC and HDI (r= 0.464, p= 0.003), life expectancy at birth (r= 0.416, p=0.008), average education years (r= 0.277, p= 0.083) and gross national income per capita (r= 0.255, p= 0.112). Moreover, it is expected that the number of incidence and mortality from BC is increased within 2012-2035 in European countries.

Conclusion: There is a positive correlation between the ASIR of BC and HDI. Moreover, there is a negative correlation between ASMR of BC with HDI. Therefore, the results of this study indicate the importance of using HDI as factors affecting the ASIR and ASMR of BC.
Perfis literários – notas sobre um projeto biográfico, crítico e ficcional
Authors: De Nadal Luiz Henrique
Published: April 2018

Este artigo tem como base o resultado de um projeto independente, realizado pelo pesquisador desde maio de 2012. O site Isto não é um cachimbo – Perfis Literários (www.istonaoeumcachimbo.com) é voltado à experimentação do formato biográfico breve, por meio do qual foram abordados 12 escritores contemporâneos. Levados à condição de objeto de estudo, os perfis literários são defendidos como uma ferramenta crítica inscrita entre o biográfico, o ficcional e o ensaístico. Diante da problemática do retorno do autor, o pastiche do perfil jornalístico surge como forma renovada de retratar o escritor do novo milênio. Ademais, um reconhecimento do circuito literário é feito com a ajuda dos estudos de Ítalo Moriconi e Paula Sibilia. Leva-se em consideração ainda a insuficiência da função autor concebida por Michel Foucault em conjunto com questões acerca do biográfico trazidas por Philippe Lejeune e Leonor Arfuch.

Abstract:

Introduction and aim: By using the database of the National Registry of Myocardial Infarction, the authors examine the prognosis of patients treated with acute myocardial infarction, in case of whom there was new or presumably new left bundle branch block (nLBBB) on the ECG recorded at hospitalization. Method: We recorded the details of 18 091 patients treated with acute myocardial infarction (AMI) between 1 January 2014 and 30 June 2015 in the National Registry of Myocardial Infarction. In case of 8334 patients, the clinical diagnosis was ST-elevation myocardial infarction (STEMI), whereas in 9757 cases it was non-ST elevation myocardial infarction (NSTEMI). In the STEMI population we examined the clinical characteristics and prognosis of patients with ST-elevation (n = 7937) and nLBBB (n = 397). We used the proportional hazards regression model (Cox-regression) to examine mortality. Results: In the AMI patient population, we found LBBB in 1274 cases (7%). In case of STEMI clinical diagnosis, the patients belonging to the nLBBB subpopulation (n = 397) were older, and the proportion of men and the occurrence of co-morbidities was higher than in case of those who had ST-elevation on their ECG recorded at hospitalization. The mortality rate of the LBBB population was higher than that of the ST-elevation patient population in both the 30-day (25.4% versus 12.4%) and the 1-year period (47.3 versus 19.9%). Percutaneous coronary intervention (PCI) had significantly lower mortality in both populations. In the course of a multifactorial analysis we verified the independent prognostic significance of LBBB: the hazard ratio compared to ST-elevation was 1.33 (95% confidence interval: 1.10–1.62), checked for gender, age, occurrence of PCI, systolic blood pressure, cardiac frequency, serum creatinine difference, and the details of five anamneses/co-morbidities. Conclusion: The admission ECG has prognostic significance. Patients with LBBB have poorer prognosis compared to patients with ST-elevation on admission ECG. Orv Hetil. 2018; 159(17): 677–681.

Abstract:

Introduction and aim: The aim of our study was to analyse the public price of the montelukast sodium therapy in Hungary. Method: Data derived from the nationwide pharmaceutical database of the Hungarian National Health Insurance Fund Administration. We observed the turnover and price of the medicaments containing the active substance montelukast sodium from 2007 to 2015. Accordingly, our indicators were: consumer price, DCT (daily cost of therapy), co-payment, quasi co-payment, DOT (days of treatment). Results: Due to the increasing DOT, the total amount of the public price paid by the patients increased until 2011, reaching the amount of 1 million USD; then, due to the generic competition and the blind bid methods, it decreased to 490 000 USD. The total amount of the public price of the brand-name Singulair moved to the generics during 3 years (2011–2014). The DCT of the originator Singulair 10 mg tablets decreased from 1.1 USD to 0.34 USD; the DCT of the generic product Montelukast TEVA decreased from 0.67 USD to 0.16 USD in the period under review. Conclusion: Due to the generic competition, the patients’ access to drugs containing montelukast sodium increased significantly: the DOT increased, the co-payment decreased.

Abstract:

Introduction and aim: To present our results on femtosecond laser-assisted penetrating keratoplasty. Patients and method: Twenty-five eyes of 25 patients underwent surgery with the following indications: pseudophakic bullous keratopathy (n = 10), keratoconus (n = 4), corneal dystrophy (n = 5), corneal scar (n = 4), band keratopathy (n = 2). Trephination of both the donor and recipient corneas were performed with VisuMax femtosecond laser device (Carl Zeiss Meditec AG, Jena, Germany). In each case, trephinaton of the donor tissue was performed first with an artificial anterior chamber (Moria, Antony, France). For the surgical plan and in the postoperative period we obtained different corneal imaging modalities. The corneal power was measured with corneal topography (TMS-4, Tomey, Nürnberg, Germany) and Scheimpflug tomography (Pentacam HR, Oculus, Wetzlar, Germany). The central corneal thickness was evaluated with Pentacam and corneal endothelial cell density was measured with specular microscopy (SP3000P, Topcon, Tokyo, Japan). The corneal structure was imaged with anterior segment optical coherence tomography (Visante, Carl Zeiss Meditec AG). All measurements were performed every 3 months in the first year and yearly thereafter. The follow-up period was 3 years in every case. Results: The corrected decimal visual acuity showed an improvement from a preoperative 0.1 ± 0.1 to a postoperative 0.71 ± 0.18 value at the end of the follow-up period (p = 0.03). All corneal grafts maintained their transparency, there were no immunological rejection during the follow-up. Topographical astigmatism was 4.5 ± 3.1 D in the first month; it showed a decreasing tendency, but there was no significant change in the 3-year period. The mean central corneal thickness changed with 60 µm during the follow-up; there was no significant difference between the first month (564 ± 52 µm) and the third year (596 ± 64 µm) mean pachymetry values (p = 0.1). The mean endothelial cell density decreased first, then remained stable, but did not change significantly from the first (1641 ± 433 cells/mm2) to the last postoperative visit (1220 ± 391 cells/mm2, p = 0.1). Conclusions: In the case of femtosecond laser-assisted penetrating keratoplasty, trephination of the donor and recipient cornea is performed automatically in a highly precise fashion. The accurate cutting surface provides excellent wound apposition and healing. Both anatomical and functional rehabilitation of patients undergoing surgery are favourable and fast.

Preemptív és preventív analgesia – a perioperatív fájdalomcsillapítás fontos eleme
Authors: Szedlák Balázs , Mitre Calin , Fülesdi Béla
Published: April 2018

Abstract:

In this review, the definition and history of preemptive analgesia and the progress of its conception will be summarized. In the physiology-pathophysiology chapter, central sensitization, the key component of the evolution of postoperative pain, and the neurochemical processes in its background will be explored. Tissue damage caused by surgical incision consists of mechanical and inflammatory components, and it has high importance in the postoperative pain management. The preemptive approach of pain management means more than just preincisional analgesia, it includes the application of multifactious synergistic medication at the same time accordingly. All of these knowledges finally became complete in the conception of the perioperative approach of preventive pain management, which covers the premedication and mental support of a patient in the preoperative setting, furthermore consumes the whole armamentarium of the preemptive (preoperative), intraoperative and postoperative analgesia regimen as well. In practice, procedure-specific pain management should be highlighted, since it is based on the different extents and types of tissue trauma caused by various operations.

Congenitalis vitiumok genetikai heterogenitása és komplexitása
Authors: Nagy Dóra , Széll Márta
Published: April 2018

Abstract:

Congenital heart defects are the most common birth defects, they account for approximately one third of all cases. They are clinically heterogeneous, vary widely in severity, treatability and prognosis and may occur as part of multiple developmental disorders, such as chromosome aberrations, microdeletion syndromes and monogenic diseases, or as isolated defects. Syndromic forms account for 25–40%, isolated forms for 60–75% of all cases. With conventional cytogenetic and next-generation molecular genetic methods, numerous genetic alterations have been identified in evolutionarily highly conserved genes of transcriptional regulators, signaling molecules and structural proteins, which are critical to normal cardiogenesis, mostly in cases with syndromic congenital heart defects. On the other hand, the genetic cause can be detected only in around 11% of isolated heart defects. The survival rate and life quality of patients with congenital heart defects have improved significantly in the last decades thanks to the remarkable development of prenatal, postnatal diagnostics as well as of heart and thoracic surgery of cardiovascular diseases. Since the number of patients, living into adulthood and reproductive age, is constantly increasing, the better understanding of the genetics of congenital heart defects may be crucial for the diagnosis, prognosis and positive family planning of patients.

The arrow leaf abelmoschus rhizome (Hibiscus sagittifolius Kurz), or Sam Bo Chinhin Vietnamese, is a perennial suffrutex herb from which the tuber root is used as a medicine in folk remedy. This species is widely distributed and can be found on many terrains across South East Asia. With an aim to create a large number of uniform and high-quality H. sagittifolius transplants in vitro, effects of some environmental factors such as photoperiod and temperature on the photoautotrophic growth of H. sagittifoliusin vitro plants were investigated. In vitro single nodal cuttings, each with an unfolded leaf, were cultured photoautotrophically (without sucrose and vitamins) on mineral SH medium, under light intensity of 150 µmol m-2 s-1, temperature of 24oC ± 2oC, relative humidity (RH) of 55% ± 5% and three different photoperiods (8, 12 or 16 h d-1) in the first experiment. Commercial polypropylene bags (V = 1,000 ml), attached with two filter-paper membranes, were used as culture vessels. After 42 days of culture, H. sagittifolius plants under the photoperiod of 16 h d-1 had the greatestincreased fresh weight (502.3 mg/plt), increased dry weight (39.5 mg/plt) and leaf area (17.0 cm2) than those put under 8 hd-1or 12 h d-1. In addition, H. sagittifolius plants also showed statistical differences in growth when photoautotrophically cultured in different air temperature regimes, including 28/25oC (photo-/dark period), 25/25oC and 20/25oC. Increased fresh weight (775 mg/plt), increased dry weight (62 mg/plt) and leaf area (22.7 cm2) of in vitro H. sagittifolius plants were the greatest when temperature was maintained at 28 oC during photoperiod. On the contrary, the photoperiod temperature of 20oC resulted in the shortest shoot length and root length of H. sagittifoliusplants. In conclusion, this study proved that H. sagittifolius plants had the best growth when cultured on SH medium, without sucrose and vitamins supplementation, under light intensity of 150 µmol m-2 s-1, RH 55% ± 5%, photoperiod of 16 h d-1, temperature regime of 28/25oC(photo-/dark period). Citation: Nguyen Thuy Phuong Duyen, Tran Thi Van, Nguyen Le Thu Minh, Nguyen Thi Quynh, 2017.

Abstract This study aimed to verify the performance of the information produced by the GPM (Global Precipitation Measurement) mission and TRMM (Tropical Rainfall Measurement Mission) on the eastern region of São Paulo state, based on a comparison of rainfall data from DAEE (Department of Waters and Electric Energy of São Paulo State). The comparison was done by comparing spatially aggregated information from both sources. In order to analyze the results, we measured: (1) Relative Difference, (2) BIAS and (3) Root Mean Square Error (RMSE). It was found that the relative differences were in the range of -20% to 20% for both missions. Analyzing the BIAS for both satellites it was observed that 68% of the measurements were overestimated. The highest agreement was obtained for the mesoregion of Campinas and the lowest for Araraquara. In the TRMM, the lowest RMSE values were found in the Araraquara mesoregion and the highest in Piracicaba. In the GPM the closest measured values were observed in the Piracicaba mesoregion, while the most distant values were identified in Araraquara. All the analyzes of this work demonstrated similarity between the errors generated by both satellites. New comparison studies are needed to better understand the products.

Resumo No presente artigo é proposto um modelo híbrido capaz de realizar previsão de velocidade do vento (médias mensais e horárias) com boa acurácia em regiões do nordeste brasileiro. Este modelo é elaborado a partir da combinação entre dois modelos, o Auto-Regressivo Integrado de Médias Móveis com entradas de Variáveis Exógenas (ARIMAX) e Redes Neurais Artificias (RNA). A escolha por estes modelos foi motivada pelo fato de que os mesmos conseguem incorporar ambas características lineares (ARIMAX) e não-lineares (RNA) comumente existentes em séries temporais. O modelo híbrido relaciona pressão, temperatura e precipitação com velocidade do vento, a fim de considerar características meteorológicas locais importantes. É possível constatar a eficiência do modelo híbrido para fornecer bons ajustes aos dados observados das velocidades dos ventos, sendo esta afirmação baseada nos valores encontrados por medidas de acurácia, exemplo, com erro percentual médio de aproximadamente 5,0%, e valor do coeficiente de eficiência de Nash-Sutcliffe de 0,96. Estes resultados confirmam a existência de precisão para as velocidades dos ventos previstas acompanhando o perfil de suas observações, em especial é possível identificar semelhanças entre ambas as séries temporais (em termos de valores máximos e mínimos), mostrando assim, a capacidade do modelo em representar características de sazonalidade.

Published: April 2018

Resumo Em janeiro de 1989, a estação meteorológica convencional de Rio Grande, RS, pertencente ao Instituto Nacional de Meteorologia, mudou-se da área central da cidade para o campus da Universidade Federal do Rio Grande. Com os dados dessa estação, no início da década de 2000, foi publicado um livro com as Normais Climatológicas Provisórias (NCP) de Rio Grande, no período de 1991 a 2000, seguindo as normas da Organização Meteorológica Mundial (OMM). Passada mais de uma década dessa publicação, foi possível atualizar esse estudo considerando o período de 1991 a 2010. Portanto, apresenta-se um roteiro para controle de qualidade de dados de estações meteorológicas convencionais de superfície e as NCP de 1991 a 2010 de Rio Grande, bem como uma comparação entre as NCP das décadas 1991-2000 e 2001-2010. Como foi identificada não-homogeneidade nas séries temporais de umidade relativa e intensidade do vento, as NCP não foram computadas para essas variáveis. Rio Grande é uma cidade com pouca variabilidade mensal de precipitação, possui verão quente e inverno frio e, de acordo com a classificação climática de Köppen-Geiger, o clima é temperado sempre úmido e com verão quente (Cfa) e, pela classificação de Strahler, é subtropical úmido.
Applicability of TRMM Precipitation for Hydrologic Modeling in a Basin in the Northeast Brazilian Agreste

Published: April 2018

Abstract Determining precipitation using remote sensing is gaining space in hydrologic studies, helping make up for the lack of data in many regions of Brazil. The products from satellite TRMM (Tropical Rainfall Measuring Mission) are widely applied in studies in Brazil, but there are still few results about their applicability for hydrologic modeling in the Northeast Region, which is characterized by an irregular precipitation regime. The objective of this study is to evaluate the feasibility of using the TRMM 3B42 V7 data for hydrologic modeling in the Japaratuba river basin in Sergipe at three timescales: daily, every ten days, and monthly. The comparative analysis between the rainfall data from rain gauges and TRMM did not indicate satisfactory adequacy at these studied scales, since the TRMM data underestimated the total rainfall for all stations used in the study. However, for the hydrologic modeling, acceptable values were obtained for the efficiency coefficients evaluated only for the ten-day and monthly scales.

RESUMO O objetivo do presente trabalho foi determinar a presença de anticorpos para Leishmania infantum, Neospora caninum e Toxoplasma gondii, por meio da reação de imunofluorescência indireta (RIFI), em cães (n=78) provenientes da região central do Rio Grande do Sul, necropsiados no Hospital Veterinário da Universidade Federal de Santa Maria (UFSM), bem como avaliar os dados epidemiológicos, sazonais e anátomo-histopatológicos. Do total de animais avaliados, 67,9% (53/78) apresentaram soropositividade para ao menos um agente. A ocorrência de anticorpos para L. infantum, N. caninum e T. gondii foi de 33,3 (26/78), 37,1 (29/78) e 43,5% (34/78), respectivamente. Detectaram-se monoinfecções em 9,4% (5/53) para L. infantum, 18,8% (10/53) para N. caninum e 20,7% (11/53) para T. gondii. As coinfecções foram observadas em 27/53 (50,9%) dos animais. As infecções ocorreram independentemente de idade, sexo, procedência ou raça (P>0,05). Não se verificaram lesões anatomo-histopatológicas relacionadas aos agentes pesquisados, caracterizando-os como animais assintomáticos. Os resultados confirmaram a exposição de cães a esses protozoários na região central do RS e, em especial, demonstraram a circulação do agente causador da leishmaniose em uma área considerada indene para a enfermidade.

Published: April 2018

ABSTRACT Van fish is a fish that can live in soda water at pH 9-10. Van fishing area is a very important source of protein for the people. The variations in tissue metal levels according to gender and weight in Van fish (Alburnus tarichi, Güldenstadt 1814) were studied. This study was conducted for the first time in Van fish. Which it is very important for living organisms Calcium(Ca), magnesium(Mg), sodium(Na), potassium(K), cobalt(Co), chromium(Cr) and lithium(Li) elements levels in the muscle, liver, gill, gonad, and brain tissues of Van fish were investigated by using inductively-coupled plasma-optic emission spectroscopy (ICP-OES). The results were evaluated in two groups as macro-elements(Ca, Mg, Na, K) and trace-elements(Co, Cr, Li). Cobalt concentration in brain tissue was found to be higher than those in other tissues. Also, male fish had higher metal concentrations than female fish and their metal levels in brain and gonad tissues varied with their weight (P<0.05). This study shows that consumption of Van fish can be consumed to supply some necessary minerals required for a healthy nutrition.

RESUMO: Objetivou-se com este estudo determinar os aspectos epidemiológicos da infecção pelo Vírus da Língua Azul (VLA) em bovinos leiteiros na microrregião de Garanhuns, Estado de Pernambuco, Brasil. Foram coletadas 384 amostras de soro de bovinos fêmeas em idade reprodutiva, procedentes de 20 propriedades dos 19 municípios que compõem a região. As amostras foram testadas com a prova de imunodifusão em gel de agarose (IDGA) para pesquisa de anticorpos anti-VLA. Observou-se ocorrência de 71,3% (274/384; IC 95% - 66,5% - 75,7%) de animais positivos. Em 100% das propriedades houve ao menos um animal soropositivo. Os fatores de risco identificados foram: presença de áreas alagadas (OR=11,8; p=0,001), não realizar controle de insetos (OR=2,1; p=0,033), rebanho aberto (OR=2,1; p=0,001) e utilização de inseminação artificial (OR=8,8; p=0,003). Este é o primeiro registro de detecção de anticorpos anti-VLA em bovinos no Estado de Pernambuco. Conclui-se que a infecção pelo VLA ocorre em bovinos na área estudada e sugere-se que medidas de controle baseadas no manejo higiênico-sanitário e biosseguridade sejam implantadas para evitar a propagação do vírus, tais como: eliminação de áreas alagadiças; controle de insetos; utilizar sêmen na inseminação artificial com atestado sanitário; realizar exames sorológicos ao adquirir animais.

Published: April 2018

ABSTRACT The present study evaluates and compares the phenology, pollination biology and breeding systems of Chamaecrista desvauxii (Collad.) Killip.and Clitoria laurifolia Poir. in a coastal plain degraded by sand mining in São Paulo State, Brazil, from January 2006 to May 2008. Flowering and fruiting events occurred in the warm and rainy season. Both species are self-compatible but only C. desvauxii was pollinator-dependent to set fruits. A small group of bees, comprising Eufrisea sp., Eulaema (Apeulaema) cingulata and Bombus morio, accessed the male and female floral structures and moved among individuals resulting in cross-pollinations. However, only B. morio was a frequent visitor and an effective pollinator. Although recruitment and survival of population in the study area are high for both species, we observed lower abundance and richness of visitors suggesting the possible lack of pollinators and pollen limitation.

Published: April 2018

Microalgae Pseudopediastrum
boryanum (Turpin) E. Hegewald was
chosen as a subject for the present research due to its potential uses of
wastewater treatment and biodiesel production. In the present study, we
investigated the growth and biomass production of P. boryanum through
use of semi-continuous cultures employing two growth media (Allen and BG-11).
In our previous study, P. boryanum was isolated from different
freshwater reservoir through the dilution technique. The isolated P.
boryanum strain was inoculated with 270 mL of medium + 30 mL of suspension
culture and the 16:8 light/dark
photoperiod was applied. Optical density was recorded by using UV-Visible spectrophotometer at 670 nm, and cell
count examination was performed through drop count method. Besides, dry weight
and chlorophyll-a concentration of strain were determined. The highest cell density (3.67x106 cells/mL), dry weight
(0.032 g/mL) and chlorophyll-a (16.39 µgL-1) production were
observed in the Allen medium. Growth rates of P. boryanum
were found to be 0.6676 d-1 in the Allen and 0.6021 d-1
in the BG-11 medium.
