Bioconversion of Waste Fiber Sludge to Bacterial Nanocellulose and Use for Reinforcement of CTMP Paper Sheets
Authors: Chen Genqiang , Wu Guochao , Alriksson Björn , Wang Wei , Hong Feng , Jönsson Leif
Published: September 2017

Utilization of bacterial nanocellulose (BNC) for large-scale applications is restricted by low productivity in static cultures and by the high cost of the medium. Fiber sludge, a waste stream from pulp and paper mills, was enzymatically hydrolyzed to sugar, which was used for the production of BNC by the submerged cultivation of Komagataeibacter xylinus. Compared with a synthetic glucose-based medium, the productivity of purified BNC from the fiber sludge hydrolysate using shake-flasks was enhanced from 0.11 to 0.17 g/(L × d), although the average viscometric degree of polymerization (DPv) decreased from 6760 to 6050. The cultivation conditions used in stirred-tank reactors (STRs), including the stirring speed, the airflow, and the pH, were also investigated. Using STRs, the BNC productivity in fiber-sludge medium was increased to 0.32 g/(L × d) and the DPv was increased to 6650. BNC produced from the fiber sludge hydrolysate was used as an additive in papermaking based on the chemithermomechanical pulp (CTMP) of birch. The introduction of BNC resulted in a significant enhancement of the mechanical strength of the paper sheets. With 10% (w/w) BNC in the CTMP/BNC mixture, the tear resistance was enhanced by 140%. SEM images showed that the BNC cross-linked and covered the surface of the CTMP fibers, resulting in enhanced mechanical strength.

Published: September 2017

In order to improve the classification accuracy of recognizing short-circuit faults in electric transmission lines, a novel detection and diagnosis method based on empirical wavelet transform (EWT) and local energy (LE) is proposed. First, EWT is used to deal with the original short-circuit fault signals from photoelectric voltage transformers, before the amplitude modulated-frequency modulated (AM-FM) mode with a compactly supported Fourier spectrum is extracted. Subsequently, the fault occurrence time is detected according to the modulus maxima of intrinsic mode function (IMF2) from three-phase voltage signals processed by EWT. After this process, the feature vectors are constructed by calculating the LE of the fundamental frequency based on the three-phase voltage signals of one period after the fault occurred. Finally, the classifier based on support vector machine (SVM) which was constructed with the LE feature vectors is used to classify 10 types of short-circuit fault signals. Compared with complementary ensemble empirical mode decomposition with adaptive noise (CEEMDAN) and improved CEEMDAN methods, the new method using EWT has a better ability to present the frequency in time. The difference in the characteristics of the energy distribution in the time domain between different types of short-circuit faults can be presented by the feature vectors of LE. Together, simulation and real signals experiment demonstrate the validity and effectiveness of the new approach.
A New Hydrogen Sensor Based on SNS Fiber Interferometer with Pd/WO3 Coating
Authors: Shao Jinxin , Xie Wenge , Song Xi , Zhang Yanan
Published: September 2017

This paper presents a new hydrogen sensor based on a single mode–no core–single mode (SNS) fiber interferometer structure. The surface of the no core fiber (NCF) was coated by Pd/WO3 film to detect the variation of hydrogen concentration. If the hydrogen concentration changes, the refractive index of the Pd/WO3 film as well as the boundary condition for light propagating in the NCF will all be changed, which will then cause a shift into the resonant wavelength of interferometer. Therefore, the hydrogen concentration can be deduced by measuring the shift of the resonant wavelength. Experimental results demonstrated that this proposed sensor had a high detection sensitivity of 1.26857 nm/%, with good linearity and high accuracy (maximum 0.0055% hydrogen volume error). Besides, it also possessed the advantages of simple structure, low cost, good stability, and repeatability.
A Robust Inner and Outer Loop Control Method for Trajectory Tracking of a Quadrotor
Authors: Xia Dunzhu , Cheng Limei , Yao Yanhong
Published: September 2017

In order to achieve the complicated trajectory tracking of quadrotor, a geometric inner and outer loop control scheme is presented. The outer loop generates the desired rotation matrix for the inner loop. To improve the response speed and robustness, a geometric SMC controller is designed for the inner loop. The outer loop is also designed via sliding mode control (SMC). By Lyapunov theory and cascade theory, the closed-loop system stability is guaranteed. Next, the tracking performance is validated by tracking three representative trajectories. Then, the robustness of the proposed control method is illustrated by trajectory tracking in presence of model uncertainty and disturbances. Subsequently, experiments are carried out to verify the method. In the experiment, ultra wideband (UWB) is used for indoor positioning. Extended Kalman Filter (EKF) is used for fusing inertial measurement unit (IMU) and UWB measurements. The experimental results show the feasibility of the designed controller in practice. The comparative experiments with PD and PD loop demonstrate the robustness of the proposed control method.

Authors: Xiao Zelei , Du Xinya , Wu Chuanqing
Published: September 2017

Nowadays, in China, there exist obvious regional economic differences. However, narrowing such differences involves solving the problem of regional innovation differences. Furthermore, regional innovation capability disparity is an important factor in explaining the imbalances between regional economic development and international economic development. Hence, the study first adopts the Theil index decomposition formula to analyze innovation difference and evolution law in China and its four regions during 1998–2013 from the perspective of high-tech industries. The study explains the reasons for the differences in regional innovation capability on the spatial and factorial levels. The study then analyzes the convergence of innovation capability on different space-scales by applying the spatial panel of the β convergence model. The analyses show that 2007 was the important inflection point in China’s regional innovation capability difference pattern; since then, the convergence speed of regional innovation capability has accelerated significantly.

Authors: Yuan Xueliang , Zhang Xiaoyu , Liang Jiaxin , Wang Qingsong , Zuo Jian
Published: September 2017

The rapid development of the building industry has become an important driving force for the fast growing energy use in China. The building industry contributed 26.4% of China’s GDP, and the building energy use accounted for 33% of the total energy use in China. Building energy conservation plays an important role in reaching the peak of carbon emissions before 2030, which was committed by the Chinese government in the Paris Agreement. Building energy conservation is a complex system. The guidance and support of government policies are one of the important issues. This research analyzed the institutional framework for building energy conservation in China. The roles and functions of each institution were critically reviewed. The policy system for building energy conservation was also analyzed, which included National Laws; Regulations of the State Council; Provisions of Ministries under the State Council; and National Standards, Plans and Programs. The suggestions for further improvements were drawn from the critical analysis such as defining clear and specific responsibility of management institutions, improving regulations and standard system, establishing the market leading mechanism, etc. This research draws an overall picture of the building energy conservation in China from the policy and institutional perspective. Findings provide a useful reference for increasing environmental performance in the building industry.
Operating Strategy for Local-Area Energy Systems Integration Considering Uncertainty of Supply-Side and Demand-Side under Conditional Value-At-Risk Assessment
Authors: Shi Jiaqi , Wang Yingrui , Fu Ruibin , Zhang Jianhua
Published: September 2017

To alleviate environmental pollution and improve the energy usage efficiency of terminals, energy systems integration (ESI) has become an important paradigm in the energy structure evolution. Power, gas and heat systems are becoming tightly interlinked with each other in ESI. The dispatching strategy of local-area ESI has significant impact on its operation. In this paper, a local-area ESI operational scheduling model based on conditional value-at-risk (CVaR) is proposed to minimize expected operational cost, which considers the uncertainty of energy supply-side and demand-side as well as multi-energy network constraints, including electrical network, thermal network and gas network. The risk cost is analyzed comprehensively under the condition of under- or overestimated cost. On this basis, a hybrid method combining particle swarm optimization with interior point algorithm is executed to compute the optimal solutions of two-stage multi-period mixed-integer convex model. Finally, a case study is performed on ESI to demonstrate the effectiveness of the proposed method.

Published: September 2017

Resource depletion, population growth and environmental problems force companies to collect their end of life (EOL) products for reuse, recycle and refurbishment through reverse supply chain management (RSCM). Success in collecting the EOL products through RSCM depends on the customers’ participation intention. The objectives of this study are: (1) To examine the important factors influencing customers’ attitude to participate in RSCM; (2) To examine the important factors influencing customers’ subjective norm to participate in RSCM; (3) To examine the main factors influencing customers’ perceived behavioral control to participate in RSCM; (4) To examine the influence of attitude, subjective norms and perceived behavioral control on customers’ participation intention in RSCM. The Decomposed Theory of Planned Behaviour (DTPB) has been chosen as the underpinning theory for this research. The research conducted employed the quantitative approach. Non-probability (convenience sampling) method was used to determine the sample and data was collected using questionnaires. Partial Least Squares-Structural Equation Modeling (PLS-SEM) technique was employed. A total of 800 questionnaires were distributed among customers of electronic products in Malaysia. Finally, the questionnaire was distributed among the customers in electronic retailer companies based on convenience sampling method. The empirical results confirm that consumers perception about the risk associated with EOL electronic products, consumers’ ecological knowledge and relative advantages associated with reuse, repair and recycling can influence the attitude of consumers to return the EOL products for reuse, repair and recycling to producer.

Authors: Criado-Gomis Ana , Cervera-Taulet Amparo , Iniesta-Bonillo Maria-Angeles
Published: September 2017

This paper proposes sustainable entrepreneurial orientation (SEO) as a multidimensional construct that offers researchers the possibility of empirically testing their theoretical proposals in the sustainable entrepreneurship field. The authors propose an integration of different theories. In accordance with the dynamic capabilities view, SEO is approached under an organizational paradigm of strategic orientations delimited by competitive culture and multiple orientation perspectives. Furthermore, SEO’s nature is conceived at a firm-based entrepreneurship level and is based on an integrated triple bottom line sustainability. This approach is conceptualized using a categorization scheme and defined in accordance with the organizational predisposition perspective. Several research lines are proposed, all based on relational models with SEO as the key concept.
Citizen Science for Urban Forest Management? Predicting the Data Density and Richness of Urban Forest Volunteered Geographic Information
Authors: Foster Alec , Dunham Ian , Kaylor Charles
Published: September 2017

Volunteered geographic information (VGI) has been heralded as a promising new data source for urban planning and policymaking. However, there are also concerns surrounding uneven levels of participation and spatial coverage, despite the promotion of VGI as a means to increase access to geographic knowledge production. To begin addressing these concerns, this research examines the spatial distribution and data richness of urban forest VGI in Philadelphia, Pennsylvania and San Francisco, California. Using ordinary least squares (OLS), general linear models (GLM), and spatial autoregressive models, our findings reveal that sociodemographic and environmental indicators are strong predictors of both densities of attributed trees and data richness. Although recent digital urban tree inventory applications present significant opportunities for collaborative data gathering, innovative research, and improved policymaking, asymmetries in the quantity and quality of the data may undermine their effectiveness. If these incomplete and uneven datasets are used in policymaking, environmental justice issues may arise.
Assessing the Uncertainty of Multiple Input Datasets in the Prediction of Water Resource Components
Authors: Kamali Bahareh , Abbaspour Karim , Yang Hong
Published: September 2017

A large number of local and global databases for soil, land use, crops, and climate are now available from different sources, which often differ, even when addressing the same spatial and temporal resolutions. As the correct database is unknown, their impact on estimating water resource components (WRC) has mostly been ignored. Here, we study the uncertainty stemming from the use of multiple databases and their impacts on WRC estimates such as blue water and soil water for the Karkheh River Basin (KRB) in Iran. Four climate databases and two land use maps were used to build multiple configurations of the KRB model using the soil and water assessment tool (SWAT), which were similarly calibrated against monthly river discharges. We classified the configurations based on their calibration performances and estimated WRC for each one. The results showed significant differences in WRC estimates, even in models of the same class i.e., with similar performance after calibration. We concluded that a non-negligible level of uncertainty stems from the availability of different sources of input data. As the use of any one database among several produces questionable outputs, it is prudent for modelers to pay more attention to the selection of input data.
Use of Cotton as a Carbon Source for Denitrification in Biofilters for Groundwater Remediation
Authors: Aloni Amir , Brenner Asher
Published: September 2017

This study is part of a comprehensive research aimed at the development and application of the “Water Sensitive Cities” idea in Israel. This is a sustainable concept, incorporating among others the harvesting, treatment, and reuse of storm-water. The use of engineered biofiltration systems for the harvesting and treatment of storm-water in Israel is complicated due to the prolonged dry climate period, spanning 7–8 months of the year. Therefore, the tactic suggested is to use a hybrid biofiltration system for both storm-water harvesting/polishing during winter, and for remediation of nitrate-contaminated groundwater during summer. This paper focuses on the summer design (denitrification) configuration. In preliminary experiments, it was found that crude cotton could serve as an effective carbon source for denitrification. Further results are reported herein regarding the design and operation of biofilter columns applied for the treatment of synthetic mixtures simulating nitrate-contaminated groundwater. The columns were composed of crude cotton wool and polyethylene beads, which prevented the effect of cotton compression. This application was shown to enable controlled removal of nitrate to low levels, while emitting very low concentrations of total organic carbon (TOC) and nitrite. It was also concluded that a biofilter requires judicious design and operation, since complete removal of nitrogen oxides might lead to the formation of undesired compounds such as sulfides due to the development of anaerobic conditions.

Published: September 2017

Jharkhand is a state in the eastern part of India. The tropic of Cancer (23 and a half degree north line) passes through Ranchi district in Jharkhand. Mud huts with burnt clay tiled roofs in Ranchi district in Jharkhand are an integral component of the state’s vernacular architecture. They come in various shapes, with a number of them having a courtyard type of plan. In general, it has been stated that courtyard type dwelling units show better thermal performance during summer and winter. In this paper, three types of mud huts with courtyards are taken as a study and through temperature measurements in the south side rooms and “Ecotect-Autodesk” (Version 2011) software simulations, their thermal performance during the hotter and colder parts of the year are observed. Thereafter, based on the study, the thermally better performing dwelling types in summer and winter are identified among the three sub-types studied. It is found that all courtyard type dwellings do not necessarily show better thermal performance in summer and winter in composite climate. Certain recommendations with respect to increasing thermal comfort in general in courtyard type huts are made.

To rank alternatives and to make a comparison of the obtained calculation results, two multi-criteria methods have been applied in this research.
Determination of Parametres of the Air-Void System in Airfield
Pavement Concrete Using Computed Tomography
Authors: Kowalska Danuta , Iwanowski Paweł , Kowalewska Agata
Published: September 2017

Immediately after completion airfield pavements begin a gradual deterioration that is attribute to several
factors. One of the major elements contribute to airfield pavement deterioration is exposure to the environment (freezingthawing
and de-icing salts). Air-voids microstructure in cement-based materials is an important feature related to the
freeze-thaw durability of these materials since all the adverse influences are result of potentially harmful ionic fluids
and aggressive gas transport through the concrete and the transport properties strongly depend on the morphology of the
pores inside the concrete.
For revealing the porous microstructure in airfield pavement concrete X-ray tomography method was used. New and
advance methodologies have been developed to determine the basic parameters of air entrainment in concrete (total
content of the air, specific surface area of the air-voids system, spacing factor and content of micropores) by summing
the distances traversed across a given component along a series of regularly spaced lines in one or more planes
intersecting the sample. Using the method mentioned above, to meet requirements of PN-EN 480-11 specification
(describes procedure for microscopical determination of air voids characteristics in hardened concrete), the original
software was applied – AVCT (Air Void by Computed Tomography) computer programme.
The specimens for CT testing were cylinders extracted by drilling out from the investigated concrete core or cubic
specimen. The CT method does not require any special processing of the surface of tested specimen as opposed the
common method according to PN-EN 480-11, by which the properly polished section is a prerequisite for obtaining
proper results of air voids characterization.
The paper presents the results of the evaluation of air-voids microstructure in concrete conducted with the application
of computed tomography method. Exemplary images of distribution and size of air-voids in concrete specimens have
been presented. Special attention was paid to obtain effective image resolution.

Published: September 2017

The GIS tools facilitate organised and formal creation of models presenting both the current state of and the
forecasted changes in physical environment (ones that will occur if specific conditions are satisfied). Formulated in
1962, D. L. Huff’s algorithm is gaining in popularity nowadays; it helps determine the probability of a particular
venue being chosen from amongst several competitive ones. Initially, it was used to define the optimal location of new
points of sale; but with the technological progress of the GIS and with an increased demand for studies on distribution
of venues or service points, its scope of use in urban planning is becoming more and more extensive. The results of the
study support decision-making processes and are invaluable help in selection of optimal locations.
This article presents how Huff’s algorithm and Lakshmanan-Hansen’s channel pass-through model can be used in
physical planning of cities with the focus on new trade centres. The research was based on the case study of Warsaw –
the biggest city in Poland. The analysis conducted showed not only what market share particular centres had, but it
also demonstrated what changes could be expected upon appearance of new trade centres.
The Use of GIS Technology in The Creation of Local Revitalisation
Programs as a Tool for Sustainable Urban Development
Authors: Marek Ogryzek , Krzysztof Rzasa
Published: September 2017

Revitalisation is a process of bringing degraded areas back from a state of crisis. It is carried out in a comprehensive
way, through integrated activities for the local community, space and economy, concentrated territorially, led by revitalisation
stakeholders and based on municipal (local) revitalisation programmes. The Municipal Council accepts the Revitalisation
Programme in a resolution. It includes a detailed diagnosis of the revitalisation area, including an analysis of negative
phenomena and local potentials in the area. Putting this purpose into practice makes use of GIS technology, which facilitates
the process of gathering information about the area and preparing maps, and therefore is helpful to conduct urban inventories.
GIS tools allow the location of concentrations of phenomena associated with the degradation of the urban space to be specified,
such as crime, unemployment, areas where a large number of people have been excluded. These tools are helpful in indicating
the development path for these areas. GIS tools can help find solutions to problem questions. They help justify the accepted
solutions. Building multi-criteria decision-making models in a GIS environment, taking into account the social criteria, allows
the revitalisation process of the area to proceed to fruition. The authors present the results of studies using the example of a
local revitalisation programme in the City of Olsztyn.

The role of pedestrian and bicycle traffic in Poland has growing trend. The comprehensive traffic study, conducted
in Gdansk in 2016, has confirmed the increase in the number of cyclists and their share in the modal split. Therefore, it is
particularly important to ensure the safety of this group of unprotected road users. Only in 2015 on the roads of Gdansk occurred
93 accidents (excluding collisions) involving cyclists. As a result, 101 people were injured, including nine seriously and 3
people killed. The study aim was to identify risk factors for collisions involving cyclists based on data of accidents reported to
the police. The following factors were analysed: the conditions for the drivers on the road (speed limits of, surface conditions),
conditions for cyclists (cycling infrastructure, traffic management), external conditions (time of the year, time of the day,
weather conditions), conditions organizational (type of intersection, traffic light) as well as the social aspects – the behaviour
of all users.

Published: September 2017

In the world, in Europe, and also in Poland the use of energy is growing rapidly, causing concern about the difficulty of supply, a depletion of non-renewable energy resources and the increase in negative impacts on the environment (ozone depletion, global warming, climate change, etc. caused by increased emissions of CO2) (Balaras et al. 2005). Political or economic attempts to enforce climate change, through the increase in the price of fossil fuels, lead to exclusion and growth of energy poverty therefore they cause social effects (fossil fuels become so expensive that a large part of the population cannot afford their combustion). The ideal solution would be a combination of activities aimed at the energy modernization of cities with sustainable strategies of their rebuilding. The purpose of the article is a search for the optimal way of spatial policies at the local level that enable implementation of the objectives of the energy policy of the European Union. Factors affecting changes in the pollutant emissions associated with the combustion of fossil fuels, depending on the energy efficiency of selected buildings were modelled with a use of deduction based on radial neural networks. The observations presented in this article may be relevant for other regions that are interested in reducing polutant emission and energy consumption of buildings, housing estates and cities. Taking the geographical context into account, it is especially important for those regions which benefit from financial support of the European Union.

Fitting Formulae and Constraints for the Existence of S-type and P-type Habitable Zones in Binary Systems
Authors: Wang 王兆 Zhaopeng 鹏 , Cuntz Manfred
Published: September 2017

We derive fitting formulae for the quick determination of the existence of S-type and P-type habitable zones (HZs) in binary systems. Based on previous work, we consider the limits of the climatological HZ in binary systems (which sensitively depend on the system parameters) based on a joint constraint encompassing planetary orbital stability and a habitable region for a possible system planet. Additionally, we employ updated results on planetary climate models obtained by Kopparapu and collaborators. Our results are applied to four P-type systems (Kepler-34, Kepler-35, Kepler-413, and Kepler-1647) and two S-type systems (TrES-2 and KOI-1257). Our method allows us to gauge the existence of climatological HZs for these systems in a straightforward manner with detailed consideration of the observational uncertainties. Further applications may include studies of other existing systems as well as systems to be identified through future observational campaigns.
Analyzing Exoplanet Phase Curve Information Content: Toward Optimized Observing Strategies
Authors: Placek Ben , Angerhausen Daniel , Knuth Kevin H.
Published: September 2017

Secondary eclipses and phase curves reveal information about the reflectivity and heat distribution in exoplanet atmospheres. The phase curve is composed of a combination of reflected and thermally emitted light from the planet, and for circular orbits the phase curve peaks during the secondary eclipse or at an orbital phase of 0.5. Physical mechanisms have been discovered that shift the phase curve maximum of tidally locked close-in planets to the right, or left, of the secondary eclipse. These mechanisms include cloud formations and atmospheric superrotation, both of which serve to shift the thermally bright hot-spot or highly reflective bright spot of the atmosphere away from the sub-stellar point. Here, we present a methodology for optimizing observing strategies for both secondary eclipses and phase curves with the goal of maximizing the information gained about the planetary atmosphere while minimizing the (assumed) continuous observation time. We show that we can increase the duty cycle of observations aimed at the measurements of phase curve characteristics (amplitude, phase offset) by up to 50% for future platforms such as CHaracterising ExOPlanets Satellite (CHEOPS) and JWST. We apply this methodology to the test cases of the Spitzer phase curve of 55-Cancri-e, which displays an eastward shift in its phase curve maximum as well as model-generated observations of an ultra-short period planet observed with CHEOPS.
Examining Life Goals of Community-Dwelling, Low-Income Older Adults
Authors: Howard Elizabeth P. , Louvar Kara E.
Published: September 2017

Self-care and self-management programs are touted as a means to age successfully. Yet, these programs pay little regard to a critical first step—the personal goals of older adults. The capacity to self-identify goals and pursue actions toward goal achievement transcends age. An examination of life goals identified by community-dwelling, low-income older adults indicates that functional performance mechanisms are valued. Maintenance of health and increased physical activity were the two most commonly identified personal goals within a sample of 161 community-dwelling older adults residing in subsidized housing. A third goal, increased socialization, aligns with relevant psychosocial factors and reflects the need to engage with others. The preferences of the older adult placed at the center of the care planning process strategically support goal attainment. Providing an opportunity to create and pursue self-selected life goals of older adults is worth consideration when developing and testing interventions designed to support successful aging.

Age simulation suits are used to demonstrate typical physical impairments of older age (e.g., strength and sensory losses) in younger individuals. The purpose of the current study was to describe gait performance in different age groups while wearing an age simulation suit. A total of 178 participants ages 18 to 85 (mean age = 50.4 years,
SD
= 16.4 years) were assigned according to their age decade to four groups with (ages 18 to 59) and two groups without (ages 60 to 85) the aging suit. Gait performance was measured with a gait analysis system (GAITRite
®
) while walking at a self-chosen pace. Velocity, step length, step time, and base width were measured. Comparable performance was found for step length and velocity between ages 40 and 49/50 and 59 and ages 60 and 69/70 and 85 (
p
< 0.05). Results showed no corresponding relationship between step time and base width for all age groups. Simulation training helps younger individuals better understand older adults' perspectives, allowing for more positive interactions.

Published: September 2017

L’article porte sur les tout premiers cours de l’année scolaire, en lycée, lorsque les enseignants demandent aux élèves de se présenter, soit à l’oral, soit à l’écrit par le biais de fiches de renseignements. En convoquant une approche interactionniste et ergonomique, nous nous intéressons à l’activité des enseignants et des élèves, lors de ces moments de présentations. Nous montrons que les enseignants prennent des informations sur les élèves, informations qui font instrument pour eux. En prenant ces informations, les enseignants s’attachent à préserver la face des élèves : leurs prises d’informations sont ainsi parfois empêchées, déguisées, facultatives, non normatives, ou encore privées. Toutefois, les élèves sont parfois mis dans l’embarras par les questions posées par leurs enseignants, et cherchent à préserver leur face. Enfin, nous nous attachons à croiser les regards entre enseignants et élèves, et montrons que la clairvoyance des uns sur l’activité des autres est limitée.

Cependant, cette pratique de collaboration entre des chercheurs et des praticiens n’est pas sans présenter d’importants défis relationnels. Puisque ces défis relationnels sont réels, il devient pertinent de connaître les caractéristiques et conditions relationnelles de la collaboration entre chercheurs et praticiens. Le présent article a pour objectif de mettre en relief des conditions relationnelles à prendre en compte pour appuyer les chercheurs et les praticiens dans l’établissement et le maintien d’une collaboration satisfaisante et fructueuse. Il présente les résultats d’une analyse transversale faite à partir de données recueillies dans le cadre de trois recherches mettant en relief des caractéristiques manifestes de la relation entre chercheurs et praticiens. De cette analyse, quatorze conditions relationnelles ressortent. Elles sont d’abord décrites pour ensuite être mises en relation avec des éléments énoncés et explicités dans le cadre théorique.

Le réseau international francophone Recherche avec soutient le développement de recherches qui associent directement les personnes concernées. Outre des rencontres internationales et interdisciplinaires, il développe, via une plateforme numérique, des informations et outils pédagogiques visant la diffusion de ses questionnements et travaux. Les réflexions qu’il propose sont d’ordre éthique, épistémologique et méthodologique. L’article montre comment le réseau constitue un dispositif dont la première qualité est de mettre ses membres en réflexivité sur leur propre manière d’élaborer et de mener des recherches avec les personnes qu’elles impliquent. Il montre aussi quel type de résultats produit la recherche avec. L’objectif n’est pas d’apporter des recommandations pour une meilleure manière de faire de la recherche mais il propose un cadre d’analyse applicable à la recherche-action, recherche-intervention, recherche collaborative, recherche participative, recherche socio-clinique et autres démarches associant les sujets touchés par leurs objets.
Parole d’excluEs : croisement des savoirs, des pouvoirs et des pratiques au sein de l’Incubateur universitaire Parole d’excluEs

L’article présente un portrait de l’environnement de travail collaboratif qui a été mis en place en 2007 avec la création de l’Incubateur universitaire Parole d’excluEs. Nous y présentons le cadre d’émergence et de développement de ce dispositif de recherche-action qui a été pensé comme une extension extra murale des activités de recherche de deux chercheurs de deux universités québécoises. Cette démarche, initialement centrée sur un dispositif universitaire s’est enrichi d’une dimension terrain forte avec la création d’un poste de chercheur en milieu communautaire au sein de l’organisme Parole d’excluEs. Cet enrichissement illustre un mode d’une internalisation de la capacité de recherche et développement au sein d’une organisation de développement social. Les dix années de travail conjoint entre ces deux milieux producteurs de connaissance ont donné place à des modalités de collaboration qui sont présentées et analysées. Dans le même sens, une attention particulière est accordée au processus de coconstruction des connaissances qui a pris place au sein de l’Incubateur et de l’organisation Parole d’excluEs.
Lipschitz 1-connectedness for Some Solvable Lie Groups
Authors: Cohen David Bruce
Published: September 2017

A space X is said to be Lipschitz 1-connected if every Lipschitz loop 𝛾 : S
1 → X bounds a O (Lip(𝛾))-Lipschitz disk f : D
2 → X. A Lipschitz 1-connected space admits a quadratic isoperimetric inequality, but it is unknown whether the converse is true. Cornulier and Tessera showed that certain solvable Lie groups have quadratic isoperimetric inequalities, and we extend their result to show that these groups are Lipschitz 1-connected.
Elements of -algebras Attaining their Norm in a Finite-dimensional Representation
Authors: Courtney Kristin , Shulman Tatiana
Published: September 2017

We characterize the class of RFD $C^{\ast }$-algebras as those containing a dense subset of elements that attain their norm under a finite-dimensional representation. We show further that this subset is the whole space precisely when every irreducible representation of the $C^{\ast }$-algebra is finite-dimensional, which is equivalent to the $C^{\ast }$-algebra having no simple infinite-dimensional AF subquotient. We apply techniques from this proof to show the existence of elements in more general classes of $C^{\ast }$-algebras whose norms in finite-dimensional representations fit certain prescribed properties.

Peptide vaccine strategies using Plasmodium-derived antigens have emerged as an attractive approach against malaria. However, relatively few studies have been conducted with malaria-exposed populations from non-African countries. Herein, the seroepidemiological profile against Plasmodium falciparum of naturally exposed individuals from a Brazilian malaria-endemic area against synthetic peptides derived from vaccine candidates circumsporozoite protein (CSP), liver stage antigen-1 (LSA-1), erythrocyte binding antigen-175 (EBA-175), and merozoite surface protein-3 (MSP-3) was investigated. Moreover, human leukocyte antigen (HLA)-DRB1* and HLA-DQB1* were evaluated to characterize genetic modulation of humoral responsiveness to these antigens. The study was performed using blood samples from 187 individuals living in rural malaria-endemic villages situated near Porto Velho, Rondônia State. Specific IgG and IgM antibodies and IgG subclasses were detected by enzyme-linked immunosorbent assay, and HLA-DRB1* and HLA-DQB1* low-resolution typing was performed by PCR-SSP. All four synthetic peptides were broadly recognized by naturally acquired antibodies. Regarding the IgG subclass profile, only CSP induced IgG1 and IgG3 antibodies, which is an important fact given that the acquisition of protective immunity appears to be associated with the cytophilicity of IgG1 and IgG3 antibodies. HLA-DRB1*11 and HLA-DQB1*7 had the lowest odds of responding to EBA-175. Our results showed that CSP, LSA-1, EBA, and MSP-3 are immunogenic in natural conditions of exposure and that anti-EBA antibody responses appear to be modulated by HLA class II antigens.

Background

Rheumatoid arthritis (RA) is an autoimmune disorder that usually affects joints and making them warm, painful, and swollen. The chief purpose of this study was to evaluate movements of mandible in geriatric patients suffering from RA with or without temporomandibular joint dysfunction.

Materials and methods

A total of 45 people were included in this study with age of 60 years and above. Partially or completely edentulous patients were divided into experimental and control group. Experimental group consists of 20 people suffering from arthritis and control group consists of 25 people without arthritis. Movements were recorded with or without prosthesis while mastication in both experimental and control group.

Results

Statistical evaluation of two studied groups showed decrease opening angle (p < 0.05) during mastication; however, insertion of new prosthesis showd a significant increase in values in both groups, with an increase in opening and closing angles.

Conclusion

Positive correlation was found between arthritis and movements of the mandible in older people suffering from RA.

Clinical significance

Patients suffering from RA are having restricted mandibular movements thus imposing an overall negative impact however; presence of prosthesis has been shown to enforce a positive effect on mandibular movement.
