Epidemiologia da sífilis gestacional no município de Montes Claros, Minas Gerais, Brasil / Epidemiology of gestational syphilis in the municipality of Montes Claros, Minas Gerais, Brazil

A sífilis gestacional é uma doença de notificação compulsória e nos últimos anos tem corrido aumento significativo, isso se torna preocupante porque existe grande chance de acontecer a transmissão congênita, ocasionando várias sequelas para o feto, inclusive óbito. O objetivo desse trabalho foi descrever a epidemiologia da sífilis gestacional no município de Montes Claros, MG. O estudo apresenta caráter transversal e descritivo com abordagem quantitativa. Foram avaliados os casos de sífilis gestacional notificados no Sistema de Informação de Agravos de Notificação (SINAN) no período de 2015 a 2018 no município de Montes Claros, MG, considerando as variáveis idade, período gestacional, escolaridade e ocupação da gestante. Os dados foram avaliados pelo programa SPSS 20.0 for Windows. Foi utilizado o teste Qui-quadrado para avaliar as diferenças de proporções, considerado significativo p≤0,05. Verificou-se aumento de casos notificados entre os anos de 2015 a 2018. Isso se deve em parte pela ampliação do uso de testes rápidos, redução do uso de preservativo, aprimoramento do sistema de vigilância, além da ausência de pré-natal ou baixo número de consulta pré-natais. A maior parte das notificações ocorreu em mulheres com idade entre 21 a 25 anos, com prevalência nas gestantes donas de casa com menor escolaridade. Conclui-se que a sífilis gestacional é uma infecção prevenível de diagnóstico e tratamento simples. Os resultados evidenciam a subnotificação. São necessárias políticas públicas para o enfretamento ao agente infeccioso, aliado a capacitação dos profissionais e o desenvolvimento de estratégias que alcance os grupos mais vulneráveis.
The usage of snapdragon Delila (Del) gene as a visible selection marker for the antibiotic-free transformation system

This study was conducted to assess the suitability of the Delila gene (Del) from snapdragon for use as a visible selectable marker, under the control of the cauliflower mosaic virus (CaMV) 35S promoter, to develop a plant genetic transformation system that helps to avoid using antibiotic- or herbicide-resistance genes, such as the gene for resistance against kanamycin or PPT. Following transformation, tobacco shoots showing red coloration always contained the Del gene, which was confirmed by PCR analysis. No chimerism or ploidy variation was observed during genetic transformation. In addition, the integration ratio of the transgene to the T1 progeny was 3:1, following typical Mendelian fashion. By anthocyanin analysis, the plants containing the Del gene were shown to have 80 times higher anthocyanin content than the control plants. Thus, we conclude that strong anthocyanin accumulation, as a result of the snapdragon Del gene, can be used as a visible selectable marker for genetic transformation in the tobacco plant, replacing the use of antibiotic- or herbicide-resistance genes.
Urban-Rural Relations Theory Advocated by Karl Marx and Friedrich Engels and the Equalization of Public Service in Urban-rural Areas

Marxism holds that urban-rural separation and confrontation is the inevitable result of the development of productivity, urban confrontation with the further development of productive forces will disappear, along with the eventual elimination of private property and class, the development of social productive forces to a certain height, gradually moving toward integration of urban and rural. To this end, expounded the basic views of urban-rural relations Marxist theory, discusses the development trend of the development of law and urban-rural relations, analyzes the development status quo of China's urban-rural relations and the reasons for this stage, discusses the relationship of Marxist theory promote urban and rural public service equalization of theoretical significance. Demonstrates the urban and rural public service equalization is in line with the law of choice Marxism and rural development, but also the practical choice of urban and rural development.
Correlation of genetic and morphometric types of Sventoji River catchment relief (north-east Lithuania)

The Sventoji is a river of the Baltic Upland. The catchment of the Sventoji is teardrop-shaped up to 50-60 km wide, and 160 km long. Most of the catchment is situated in the Aukstaiciai Upland and the Western Aukstaiciai Plateau. The surface of the catchment was formed by Quaternary ice sheets that deposited a moraine layer 100-200 m, the thick topographic relief dating to the late Nemunas (Weichselian) Glaciation phases. The eastern part of catchment was formed in the East Lithuanian Phase, the middle part in the South Lithuanian Phase and the western part in the Middle Lithuanian Phase. The catchment surface is composed of three different genetic relief types: the ice-marginal deposits of the East Lithuanian Phase, represented by small hills; the middle part of the Sventoji catchment, transected by a few ice-marginal ridges of the South Lithuanian Phase which form small hills; and the western part of the catchment is transected by a few asymmetric ridges of the Middle Lithuanian Phase. The eastern part dominantly comprises ice-marginal deposits with glaciolacustrine and glaciofluvial intercalation; the middle part comprises variable glaciolacustrine, basal moraine and ice-marginal deposits; the western part by basal moraine and ice-marginal deposits.

Rapid detection and E-test antimicrobial susceptibility testing of Vibrio parahaemolyticus isolated from seafood and environmental sources in Malaysia.

OBJECTIVES 
To find out the prevalence and antimicrobial susceptibility of Vibrio parahaemolyticus in seafoods and environmental sources.
 METHODS 
The study was carried out at the Center of Excellence for Food Safety Research, University Putra Malaysia; Universiti Kebangsaan Malaysia; Medical Molecular Biology Institute; and University Kebansaan Malaysia Hospital, Malaysia between January 2006 and August 2008. One hundred and forty-four isolates from 400 samples of seafood (122 isolates) and seawater sources (22 isolates) were investigated for the presence of thermostable direct hemolysin (tdh+) and TDH-related hemolysin (trh+) genes using the standard methods. The E-test method was used to test the antimicrobial susceptibility.
 RESULTS 
The study indicates low occurrence of tdh+ (0.69%) and trh+ isolates (8.3%). None of the isolates tested posses both virulence genes. High sensitivity was observed against tetracycline (98%). The mean minimum inhibitory concentration (MIC) of the isolates toward ampicillin increased from 4 ug/ml in 2004 to 24 ug/ml in 2007.
 CONCLUSIONS 
The current study demonstrates a low occurrence of pathogenic Vibrio parahaemolyticus in the marine environment and seafood. Nonetheless, the potential risk of vibrio infection due to consumption of Vibrio parahaemolyticus contaminated seafood in Malaysia should not be neglected.
Two magma bodies beneath the summit of Kīlauea Volcano unveiled by isotopically distinct melt deliveries from the mantle

Abstract The summit magma storage reservoir of Kīlauea Volcano is one of the most important components of the magmatic plumbing system of this frequently active basaltic shield-building volcano. Here we use new high-precision Pb isotopic analyses of Kīlauea summit lavas—from 1959 to the active Halema‘uma‘u lava lake—to infer the number, size, and interconnectedness of magma bodies within the volcano's summit reservoir. From 1971 to 1982, the 206Pb/204Pb ratios of the lavas define two separate magma mixing trends that correlate with differences in vent location and/or pre-eruptive magma temperature. These relationships, which contrast with a single magma mixing trend for lavas from 1959 to 1968, indicate that Kīlauea summit eruptions since at least 1971 were supplied from two distinct magma bodies. The locations of these magma bodies are inferred to coincide with two major deformation centers identified by geodetic monitoring of the volcano's summit region: (1) the main locus of the summit reservoir ∼2–4 km below the southern rim of Kīlauea Caldera and (2) a shallower magma body 4 km3 of lava erupted), must therefore be sustained by a nearly continuous supply of new melt from the mantle. The model results show that a minimum of four compositionally distinct, mantle-derived magma batches were delivered to the volcano (at least three directly to the summit reservoir) since 1959. These melt inputs correlate with the initiation of energetic (1959 Kīlauea Iki) and/or sustained (1969–1974 Mauna Ulu, 1983-present Pu‘u ‘Ō‘ō and 2008-present Halema‘uma‘u) eruptions. Thus, Kīlauea's eruptive behavior is partly tied to the delivery of new magma batches from the volcano's source region within the Hawaiian mantle plume.
Uma política de esquecimento? Invisibilidade das marcas da ditadura civil-militar em Curitiba

Este artigo analisa alguns locais utilizados pela repressão em Curitiba durante a ditadura civil-militar (1964-1985) e o processo de descaracterização pelo qual passa-ram após o final do regime, discutindo uma possível política de ocultação das marcas da ditadura na paisagem urbana. Para tanto, foram analisados testemunhos de ex-presos políticos, assim como o relatório da Comissão Estadual da Verdade Tereza Urban (CEV/PR, 2017a, 2017b), na tentativa de compreender os diferentes tipos de esquecimento que foram implantados pelo Estado e suas motivações. Por fim, verificou-se que sistemáticamente as marcas do período foram sendo apagadas, esquecidas e silenciadas, seja por intervenção do tempo ou por descaso do poder público.
Demographic and Migratory Flows Affecting European Regions and Cities

Overall predictions indicate labour shortages in the EU after 2010. The Commission Staff Working Document on Europe’s demographic future points out that from around 2017 on the shrinking population in working age will lead to stagnation and, subsequently, reduction of total employment. Against this backdrop, the EU Commission acknowledges the necessity of immigration from outside the EU to meet the requirements of the European labour market. The Fourth Cohesion Report indicates that already today, population growth depends on immigration. In the above mentioned staff working document, the Commission identified a need of further analysis for the effects of migration on Europe’s demographic future.  In response to above mentioned key policy documents the project deals with the effects of demographic and migratory flows on European regions and cities and examines the implications for regional competitiveness and European cohesion.
Analysis of Electrocardio Signal Based on Approximate Entropy

The research and detection of heart disease depends on the analysis of the characteristic of electrocardio signal. Current analysis methods mainly include: (1) time domain analysis is a common used approach. With experience learned by observation and calculation, researchers examine errors and interferences to calculate means and variances directly within time domain. Analysis quality of this method demands higher request for researchers’ experience and skill although it’s a direct and significant result. (2) Frequency domain analysis, such as spectrum estimation, is largely applied to electrocardio signal researches and clinical applications. The analysis reflects abundant electrocardio activities, but failed to show details of the characteristics due to lack of time information. (3) time-frequency domain analysis describes energy density under different time and frequency of electrocardio signal at one time. It clarifies the relationship of signal frequency’s changing along with time such as wavelet transform method. (4) Nonlinear analysis is generally applied to biomedicine signal research in recent years. Correlation dimension, kolmogorov entropy, lyapunov component are major research methods to estimate some nonlinear dynamic parameters to represent the characteristic of electrocardio signal.
A Preliminary Review of the Civil Service Sector in Sultanate of Oman

The paper is attempting to envision the functionality of the public entities within the Omani public sector. With a case study attempt as the general research design, a narrative approach was used, formed in a literature review, to explore and describe the Omani public sector and its underlying entities. It was found though that there are six entities within which the government exercises its autonomy upon the public policies and practices. These entities are: council of ministers, special councils and committees, ministries, regional public administration, public establishments, public institutes. It was also concluded that the Omani civil service system consists of three interrelating entities that are: civil service law, civil service council, and ministry of civil service. Hence, the paper avails further research initiatives upon the Omani civil service sector as it serves as a sound research platform.
Error estimates for filtered back projection

Computerized tomography allows us to reconstruct a bivariate function from its Radon samples. The reconstruction is based on the filtered back projection (FBP) formula, which gives an analytical inversion of the Radon transform. The FBP formula, however, is numerically unstable. Therefore, suitable low-pass filters of finite bandwidth are employed to make the reconstruction by FBP less sensitive to noise. The objective of this paper is to analyse the reconstruction error occurring due to the use of a low-pass filter. To this end, we prove L2 error estimates on Sobolev spaces of fractional order. The obtained error estimates are affine-linear with respect to the distance between the filter's window function and the constant function 1 in the L∞-norm. Our theoretical results are supported by numerical simulations, where in particular the predicted affine-linear behaviour of the error is observed.
Vaccine media analytics

One of medical science’s greatest achievements is the development of vaccines. Even if availability is improving, prices are dropping, evidence of effects are increasing and the side effects are fewer, an increasing number of people av voluntarily choosing not to accept vaccines.

This project do not focus on the very visible group of active vaccine opponents, but instead on the less visible group where vaccine is just one of many other issues in daily life. From a public health communication point of view this group is particularly interesting since they is in a phase where they are deciding if they should vaccinate. This group have been hard to study since they are hard to target both with traditional surveys and interview and by traditional media analytics only.

The project will use a mixed method approach for identifying and understanding this group. The methods will have a particular focus on machine learning techniques and semantic analysis. The choice of methodology together with the hosting at FISABIO and the University of Valencia coupled with secondments at the Vaccine Confidence Project at  London School of Hygiene & Tropical Medicine and with the SME Salumedia, gives the candidate an ideal environment for improving his scientific career.
Empirical Study of the Relations of Assets and Consumption——A VAR Model Based on the Data of Fujian Urban Residents

The major impact of assets on consumption is reflected in the wealth effect.By using the urban resident data of Fujian Province,the paper makes an empirical study of the wealth effect.The results reveal that the wealth effect of Fujian urban residents is weak and the ratio of financial assets to total assets is low.In order to promote economic growth in Fujian by stimulating consumption through the wealth effect of Fujian urban residents,the following measures must be taken.Firstly,multi-level financial market system must be constructed and the proportion of financial assets must be increased.Secondly,measures must be taken to increase the value of assets of the urban residents.Finally,measures must be taken to increase the disposable income of the urban residents.
The Multiplier Effect: A Classroom Exercise

Lowering taxes and raising government spending are both forms of expansionary fiscal policy. Often students mistakenly believe that their relative impact on GDP is equivalent, i.e. a dollar increase in government expenditure increases GDP by the same amount as a dollar decrease in taxes. This paper describes a classroom exercise that demonstrates a) how both fiscal stimuli create greater aggregate output and b) which fiscal stimulus spending is more effective. In this exercise, six students come to the front of class and act as business owners, the instructor acts as the government with a stimulus plan, and the remaining students are workers/consumers. Going through a sequence of financial decisions of how much to save and spend, students learn how the initial fiscal shock sets off a chain reaction, leading to successive rounds of changes in spending and income. This simple framework can then be used to evaluate the effect of relaxing standard assumptions, and to demonstrate the impact of automatic stabilizers such as taxes and transfer payments. Finally, this exercise can be used to facilitate a discussion on how the theoretical predictions differ from the actual real-world results due to credit liquidity restrictions, unemployment benefits, inflation, and governmental inefficiency.

Advanced light materials for sustainable electrical vehicles by integration of eco-design and circular economy strategies

The aim of LEVIS Project would be to develop a new manufacturing route able to fill the current industrial gap present in mass production automotive applications. By adopting an eco- and circular design concept from the design phase to the end-of-life stage, LEVIS project will develop, verify and demonstrate lightweight structural parts in electrical vehicles. Enhanced sustainability, improved raw material use-, energy- and cost efficiency, reduced weight yet high structural integrity and reliability are expected to be achieved.  LEVIS envisages the use of multi-material solutions based on fibre reinforced thermoplast.
LEVIS aims at the development of structural parts in automotive using thermoplastic based CFRP/metal hybrid materials integrated with SHM system in order to achieve a significant weight reduction while keeping the mechanical in-service performance of the targeted parts. For that, new sustainable materials, suitable manufacturing/assembly procedures, advanced simulation methodologies/workflows and innovative sensing/monitoring technologies will be developed, implemented and validated. Recyclable resins, bio-resourced CF and recycled CF will be developed and used for these parts for enhanced sustainability. The feasibility and scale-up capability of production of these lightweight materials and structural parts will be verified and demonstrated. A circular-design approach will be used for constructing the structural parts in order to maximise their service-life and enable easy, effective and efficient dismantling and reuse of the components (both CFRP- and metal-) in the parts as well as recovery of resins and fibres with sufficient quality for second-life use.
Electric field determination and magnetic topology optimization in Hall thrusters

Electric propulsion is facing new challenges. Recently, the launch of satellites has marked the debut of a new era. Going all-electric now appears as an interesting alternative to conventional systems for telecom operators. A laser spectroscopy technique was used during this research to investigate the ion velocity distribution dynamics. The different methods for determining the electric field in Hall thrusters were exposed. Two unstable ion regimes were identified and examined. Measurement uncertainties using electrostatic probes were assessed. Planar probed have been designed and tested. A thorough investigation of the influence of the magnetic field parameters on the performance of Hall thrusters was performed. The wall-less Hall thruster design was presented, and preliminary experiments have revealed its interest for the electric propulsion community.
Fostering synthetic biology standardisation through international collaboration

Synthetic Biology is an engineering research field aiming at (re)designing biological circuits for applied purposes. As any other engineering field, it strongly relies on the use of well-defined, universal and robust standard components. The outstanding success of synthetic biology in the last years should not hide the difficulties in defining biological standards. There are both historical and technical difficulties to reach that ambitious goal. On the former: the crossroad nature of synthetic biology involving mainly biologists/biotechnologists and engineers, whose views on the
standardisation of living beings tend to differ; among the latter: the intrinsic features of live (mutation, emergent properties, fitness biasses, variability and, of course, evolution). In BIOROBOOST we propose to finally overcome cultural issues and to dramatically advance in solving technical difficulties by i) gathering the most relevant stakeholders of all the aspects of standardisation in biology in Europe in a co-creation scenario; ii) by empirically testing cultural (lab-centric) standardisation practices and by promoting a consensus conceptual and technical redefinition
of biological standards; and, finally, iii) by fostering a realistic and flexible toolbox of standard biological parts, including a reduced set of specialised chassis for specific applications as well as a renewed conceptual framework to inform policy makers, scientific and other societal actors.
