Published: February 2015

RESUMO: Este artigo apresenta uma proposta de um modelo de ações que visa fornecer a cidades de pequeno porte as melhores condições sanitárias para provimento do bem estar socioambiental, atendendo simultaneamente às legislações ambientais vigentes, tomando como referência o sucesso das experiências referentes ao reuso de efluentes para fins agrícolas, através de uma análise dos projetos implantados, os quais visam à reciclagem das águas residuais. A metodologia adotada teve como base pesquisas nacionais e internacionais na temática de reuso de água e memorial de cálculo para a implantação de projetos de tratamento de efluentes. Através do modelo de tratamento de águas residuais integrado ao reuso agrícola destinados para projetos de cidades com até 20.000 habitantes, que não possuem uma destinação adequada para os efluentes gerados verificou-se que as características similares de clima e escassez de água que existem entre Israel e a região do semiárido brasileiro podem, em princípio, levar a crer que a experiência bem sucedida deste país, no campo da agricultura irrigada, utilizando águas residuais, poderá ser facilmente repetida no Brasil. A utilização das águas residuais na agricultura favorece a continuidade na produção agrícola em localidades que não possuem outra fonte de água durante a estação seca a não serem esgotos. Diante do exposto, a implantação de uma estação de tratamento de efluentes e de sistemas de irrigação adequados garante o sucesso de reuso de efluentes. Palavras-Chave: Recursos hídricos.

Authors: Ayabe Ninomiya Gabriel , Kellner Erich , Akutsu Jorge 
Published: February 2015

Resumo: A implantação ou ampliação de sistemas de abastecimento de água apresenta, como premissa básica, a determinação da vazão de demanda. Essa, por sua vez requer, dentre outros parâmetros, a avaliação do consumo percapita efetivo de água, o qual pode variar segundo características socioeconômicas, culturais e ambientais. Como o consumo de água é influenciado pelas condições da infraestrutura sanitária, existência de micromedição, poder aquisitivo do domicílio atendido, questões climáticas, entre outros, a determinação das vazões percapitas para setores de abastecimento de uma cidade, por exemplo, podem permitir um melhor planejamento da expansão dos sistemas de abastecimento de água e análises mais precisas das eventuais necessidades de melhoria e expansão da infraestrutura de abastecimento de água. O objetivo geral do presente trabalho foi o de comparar o consumo médio efetivo de água potável dos bairros Douradinho e Parque Faber II, ambos localizados na cidade de São Carlos, analisar esse consumo sob a ótica socioeconômica domiciliar, além de estimar os coeficientes do dia de maior consumo (K1) para cada um dos loteamentos. Para o loteamento Faber II, cujo rendimento domiciliar médio mensal era de R$9.448,90, o consumo médio percapita efetivo foi de 321,3 L/hab.dia, enquanto que para o loteamento Douradinho, cujo rendimento domiciliar médio mensal era de R$2.206,75, o consumo médio percapita efetivo foi de 138,3 L/hab.dia. Os coeficientes do dia de maior consumo (K1) para os birros Faber II e Douradinho resultaram em, respectivamente, 1,64 e 1,26. Palavras-chave: Sistema de Abastecimento de Água.

Students’ Perspectives on the Role of Peer Feedback in Supporting Learning
Authors: Evans Carol 
Published: February 2015

There has been a considerable growth in research considering the role of peer feedback within higher education over the last 10 years (Gielen, Dochy, & Onghena, 2011). However, there are mixed opinions regarding what peer feedback involves and its value in relation to enhancing student learning outcomes. Furthermore, for those supporters of holistic assessment designs advocating greater student involvement and agency in the assessment process (Boud & Associates, 2010), there is a tension regarding the extent to which students should be required to participate in peer feedback activities (Nicol, 2008). In developing this argument, it is known that although peer feedback can be a positive experience for students (De Grez, Valcke, & Berings, 2010), impacts on learning can also be variable, reflecting the interplay of individual and contextual factors.Adopting an interpretative phenomenological analysis approach, this article examines with students how they make sense of and use peer feedback opportunities. Informed by a personal learning styles pedagogy (PLSP; Evans & Waring, 2009, 2014), two peer feedback pedagogical interventions involving postgraduate students were implemented at two U.K. higher education institutions. Using a mixed methods approach, the role of individual and contextual variables in affecting students’ perceptions of the value of peer feedback and the PLSP approach are explored. Informed by current peer feedback debates, recommendations to inform practice are made.

Published: February 2015

Background: A broader understanding of the immune inflammatory profile of peri‐implant diseases could be helpful in the development of host‐targeted preventive and therapeutic strategies. The aim of this study is to answer two clinical questions: 1) whether patients with peri‐implantitis (PP) present higher prevalence of any specific inflammatory cytokine in peri‐implant crevicular fluid (PICF) compared with healthy patients; and 2) whether local inflammation measured in PICF can be used as a predictor for incipient PP.Methods: A systematic review of the literature on the most common cytokines released in PICF in healthy and PP‐affected sites was conducted from 1996 up to and including October 2013 using predefined search strategies. Cross‐sectional and prospective longitudinal studies were considered. Meta‐analyses were done separately for healthy, mucositis (MU), and PP outcomes.Results: Interleukin (IL)‐1β was the most studied cytokine (n = 12), followed by tumor necrosis factor (TNF)‐α (n = 10). Other cytokines were also linked to PP, such as IL‐4, IL‐6, IL‐8, IL‐10, IL‐12, and IL‐17. Statistical differences were revealed when IL‐1β release was compared between healthy implant sites and PP (P = 0.001) or MU sites (P = 0.002), respectively; when PP and MU were compared, no statistical differences could be detected (P = 0.80). For TNF‐α release, significant differences were found between healthy and PP implants (P = 0.02).Conclusions: PICF containing inflammatory mediators, such as IL‐1β and TNF‐α, can be used as additional criteria for a more robust diagnosis of peri‐implant infection. Additionally, once the inflammatory process is installed, no differences were found between peri‐implant MU and PP.
The Risk of Type 1 Diabetes Among Offspring of Immigrant Mothers in Relation to the Duration of Residency in Sweden
Authors: Hussen Hozan Ismael , Moradi Tahereh , Persson Martina 
Published: February 2015

OBJECTIVE
The risk for type 1 diabetes mellitus (T1DM) is increased in the second compared with the first generation of immigrants in Sweden. We investigated the effect of the mother’s duration of stay in Sweden on the risk of T1DM in the offspring.

RESEARCH DESIGN AND METHODS
Using data from national registries, we identified all subjects with T1DM among 984,798 children born in Sweden (aged 0–18 years) between 1992 and 2009. Incidence rate ratios (IRRs) with 95% CI were estimated using Poisson regression.

RESULTS
Offspring of mothers living in Sweden for up to 5 years had a 22% lower risk of T1DM (adjusted IRR 0.78, 95% CI 0.63–0.96) compared with offspring of mothers living in Sweden for 11 years or more. The risk increased with the mother’s duration of stay in Sweden.

CONCLUSIONS
Our findings support the hypothesis that immigration to Sweden is associated with exposure to new environmental factors that contribute to the development of T1DM in genetically susceptible individuals.

OBJECTIVE
This study used next-generation sequencing (NGS) technologies to characterize the gut virome at the onset of islet autoimmunity.

RESEARCH DESIGN AND METHODS
We conducted a case-control study nested within the Finnish Diabetes Prediction and Prevention (DIPP) cohort. The stool virome in 19 case children, who turned islet autoantibody positive before the age of 2 years and later developed clinical type 1 diabetes, and 19 tightly matched control subjects was analyzed using NGS performed from stool samples collected 3, 6, and 9 months before the onset of islet autoimmunity. Human virus findings were verified using real-time PCR.

RESULTS
One or more human viruses were present in 10.4% and bacteriophages were in 54% of the samples. The virome composition showed no association with islet autoimmunity. NGS was less sensitive and specific than real-time PCR.

CONCLUSIONS
The present data suggest no dramatic changes in the gut virome shortly before the emergence of islet autoimmunity and emphasize the need of verification of mass sequencing results when viral exposure is assessed in association studies.
New Computational Approaches to Determining the Astronomical Vessel Position Based on the Sumner Line
Authors: Chen Chih-Li , Hsu Tien-Pen , Weng Guo-Yu 
Published: February 2015

Abstract
In this paper two new approaches are developed to calculate the astronomical vessel position (AVP). Basically, determining the AVP is originated from the spherical equal altitude circles (EACs) concept; therefore, based on the Sumner line's idea, which implies the trial-and-error procedure in assumption, the AVP is determined by using the two proposed approaches. One consists in taking the great circle of spherical geometry to replace the EAC to fix the AVP and the other implements the straight line of the plane geometry to replace the EAC to yield the AVP. To ensure the real AVP, both approaches choose the iteration scheme running in the assumed latitude interval to determine the final AVP. Several benchmark examples are demonstrated to show that the proposed approaches are more accurate and universal as compared with those conventional approaches used in the maritime education or practical operations.
Methods of Calculating Ship Resistance on Limited Waterways
Authors: Skupień Emilia , Prokopowicz Jarosław 
Published: February 2015

Abstract
Nowadays predicting transportation costs is more and more important. Most significant part of inland navigation's costs are the costs of fuel. Fuel consumption is related to operating conditions of ship's propulsion system and its resistance. On inland waterways the ship resistance is strictly related to the depth of the waterway. There is a tendency to build a formula that allows its user to calculate the resistance of any inland waterway vessel, but researches claim that most of them are accurate only for particular types of ships and/or operating conditions. The paper presents selected methods of calculating ship resistance on inland waterways. These methods are examined for different types of ships and different conditions using results of model tests. The performed comparison enabled selecting the best option for pushboats and pushed barge trains, but also showed that any of the tested methods is good enough to be used for calculating the resistance of motor cargo vessels. For this reason, based on known equations and using the regression method, the authors have formulated a new method to calculate the resistance of motor cargo vessels on limited waterway. The method makes use of ship's geometry and depth of waterway in relation to ship's speed. Correlating the ship's speed with its resistance and going further with fuel consumption, enables to calculate the costs of voyage depending on the delivery time. The comparison of the methods shows that the new equation provides good accuracy in all examined speed ranges and all examined waterway depths.

Published: February 2015

Abstract
The article discusses the issue of balancing energy processes in turbine engines in operation in aeronautic and marine propulsion systems with the aim to analyse and evaluate basic operating parameters. The first part presents the problem of enormous amounts of energy needed for driving fans and compressors of the largest contemporary turbofan engines commonly used in long-distance aviation. The amounts of the transmitted power and the effect of flow parameters and constructional properties of the engines on their performance and real efficiency are evaluated. The second part of the article, devoted to marine applications of turbine engines, presents the energy balance of the kinetic system of torque transmission from main engine turbines to screw propellers in the combined system of COGAG type. The physical model of energy conversion processes executed in this system is presented, along with the physical model of gasodynamic processes taking place in a separate driving turbine of a reversing engine. These models have made the basis for formulating balance equations, which then were used for analysing static and dynamic properties of the analysed type of propulsion, in particular in the aspect of mechanical loss evaluation in its kinematic system.

An Analysis of the Tvergaard Parameters at Low Initial Stress Triaxiality for S235JR Steel
Authors: G. Kossakowski Paweł 
Published: February 2015

Abstract
This paper discusses the influence of the Tvergaard parameters, qi, which are basic constants of the Gurson-Tvergaard-Needleman (GTN) material model, on the numerically simulated load-carrying capacity of tensile elements made of S235JR steel. The elements were considered to be under static tension at low initial stress triaxiality σm/σe = 1/3. Two sets of the Tvergaard parameters qi were analyzed: those typical of structural steels and those dependent on material strength properties. The results showed that the Tvergaard parameters, qi, had influence on the load-carrying capacity of tensile elements at low initial stress triaxiality. They affected the strength curves and the changes in the void volume fractions determined for S235JR steel elements
Physical Fields During Construction and Operation of Wind Farms by Example of Polish Maritime Areas
Authors: Otremba Zbigniew , Andrulewicz Eugeniusz 
Published: February 2015

Abstract
The article discusses an important issue of technical pressure exerted on the marine environment during construction and operation of maritime wind farms (MFW) on waters of the Polish Exclusive Economic Zone. A motivation for analysing this issue is the need for attracting attention to the aspect of physical field modification as the factor which links large scale technical activity at sea with the existence and functioning of the marine ecosystem, including further consequences to its economic benefits. Based on current knowledge and authors' analyses, the scale of modifications (disturbances) of physical fields expected to take place during MFW construction and operation was assessed.

Authors: Malinowski Marcin , Kwiecień Janusz 
Published: February 2015

Abstract
In navigation practice, there are various navigational architecture and integration strategies of measuring instruments that affect the choice of the Kalman filtering algorithm. The analysis of different methods of Kalman filtration and associated smoothers applied in object tracing was made on the grounds of simulation tests of algorithms designed and presented in this paper. EKF (Extended Kalman Filter) filter based on approximation with (jacobians) partial derivations and derivative-free filters like UKF (Unscented Kalman Filter) and CDKF (Central Difference Kalman Filter) were implemented in comparison. For each method of filtration, appropriate smoothers EKS (Extended Kalman Smoother), UKS (Unscented Kalman Smoother) and CDKS (Central Difference Kalman Smoother) were presented as well. Algorithms performance is discussed on the theoretical base and simulation results of two cases are presented.
Least Squares Collocation Alternative to Helmert’s Transformation with Hausbrandt’s Post – Transformation Correction
Authors: Ligas Marcin , Banasik Piotr 
Published: February 2015

Abstract
The paper presents a least squares collocation - based alternative to Helmert’s transformation with Hausbrandt’s post – transformation correction. The least squares collocation is used as an exact predictor i.e. it honors the data, thus the problem of zero residuals on transformation control points is overcome and zero residuals are assured by the method applied. Despite the fact that the procedure is presented for Helmert’s transformation it may easily be copied to any other form of coordinate transformation. A numerical example is provided within the content of the paper.
Precision Analysis of Trimble Rtx Surveying Technology with Xfill Function in the Context of Obtained Conversion Observations
Authors: Krzyżek Robert 
Published: February 2015

Abstract
As a result of traditional geodetic surveying we usually achieve observations which are then used for calculating rectangular coordinates onto a plane along with precision evaluation. In this article the surveying methods are presented in which the situation is different. Test measurements were carried out, consisting in the measurement of a fragment of detailed control network in RTK (Real Time Kinematic) and RTX (Real Time Extended) mode with xFill function. First, the rectangular coordinates onto a plane (through the transformation of data ellipsoidal) were obtained, on the basis of which the conversion observations were determined and they were compared with each other, as well as with reference parameters - conversion observations out of detailed control network adjustment with use of the method of least squares. The results of the study allow to verify the precision and application possibilities of conversion observations obtained thanks to Trimble RTX technology with xFill function. Application of this surveying method in typical geodetic tasks is fully justifiable. Nevertheless, it is recommendable to be aware of the correlations of absolute or relative values obtained in RTX procedure to reference parameters, which in turn will enable conclusive verification of the possibilities of Trimble RTX technology application in certain geodetic surveys.
