Removal of Humic Substances by Repeated Mixing with PACl
Authors: Nagare H. , Aso T. , Yoshida S. , Ebie K.
Published: July 2016

Focusing on the improvement of removal efficiency of humic substances by coagulation, coagulation-flocculation processes were applied not only once but more than twice to the water being treated, and the effect of repeated coagulation was evaluated in jar-tests. With more than the critical dosage of PACl (15 mg/l), approximately 30% of color removal was attained in typical one-pass treatment, whilst maximum 65% removal was achieved by repeating the coagulation twice. Repeating coagulation enhances the coagulation process to achieve higher color removal efficiency, and can reduce the coagulant dosage.
Evaluation of sludge-based carbon as packing material in biofiltration in comparison to classic materials
Authors: Dorado A. D. , Hernández J. , Ribera G. , Gabriel D. , Lafuente J. , Gamisans X.
Published: July 2016

The main objective of this study is to determine the most rellevant characteristics and physical behaviour of carbon obtained from sludge (SBC) from wastewater treatment facilities and to use it as support material in a biofilter in comparison to classic materials commonly used in this purpose. Materials for comparison were selected according to previous works in the field of biofiltration including organic and inorganic (or synthetic) materials. Results obtained demonstrate that SBC is an acceptable packing material according to the main parameters to be valued in any biofilter: nutrients supply capability, high water retentivity, high adsorption capacity, to provide low pressure drop, allow for biomass attachment or a commitment among them. The study includes the performance of SBC in an operative, lab-scale biofilter besides the characterization of the adsorption capacity and pressure drop as a function of operational parameters.

Published: July 2016

The scope of this paper is to present and compare the results of (1) an extensive odour, VOC and H2S impact assessment, and (2) a complete odour, VOC and H2S air quality monitoring program at a municipal solid waste landfill (MSWL). This study was conducted over a year, with an unprecedented amount of cross-assessment techniques and data points on a 1.3 million tonnes per year MSWL. All potential landfill emission sources were characterized for odours, VOCs, CH4 and H2S using a set of over 150,000 onsite samplings & measurements. An air quality monitoring program included continuous odour, CH4 and H2S monitoring, a 12-day-frequency VOC sampling campaign, and a 24h/7d odour survey at the nearest receptors. This paper will present the standardized methodologies used and comparative results from each independent assessment program.
“In Line” Combined Storm and Wastewater Treatment System for Tropical Urban Drainage Catchments
Authors: Listanco Trina G.
Published: July 2016

This paper presents a conceptualized combined storm and wastewater treatment system for typical low income, high density drainage catchment similar to the case of Manila City. In many developing and tropical port cities in low-lying floodplains, local and regional floods and non sewered communities compound in a problem that manifests in surface water pollution. This results in particularly difficult situation to introduce major sewerage infrastructure and a centralized wastewater treatment system. Thus, to initiate and invite discussions on different and possible solutions is necessary to address the need to provide appropriate treatment systems in rapidly growing cities and urban populations. This paper aims to contribute to such discussions by suggesting possible treatment processes achievable in limited, under exploited spaces in urban drainage networks. Also the paper mentions systematic estimations relevant to assess and theoretically simulate suggested treatment system. Following Hvitved-Jacobsen etal (2002) recognition of the role of sewers as bioreactors, the proposed system takes reviewed physical and biological techniques to be installed parallel to the track of drainage channels that provides neither on-site nor off-site approaches, but “inline” treatment. Essentially, the system integrates sewers or drains in the entire treatment system. The estimated primary and secondary information on both physical and socio-economic parameters in the study site, and the adapted “alternative” principles of decentralized, small scale systems yielded a multiple site designs including the following treatment processes and units: 1) inline fine and micro screening; 2) vegetated submerged beds (VSB); 3) rotating biological contactors (RBC); and 4) “biotowers”. All were designed to capture and reduce typical wastewater constituents (TSS, BOD, TKN and Coliforms) continuously during “dry” and “average wet” conditions until year 2025. The system embodies an effective and alternative wastewater treatment system for Philippine effluent standards, replicable in other tropical urban drainage catchments.
Bridging the Divide: An Onco-Nephrologic Approach to the Monoclonal Gammopathies of Renal Significance
Authors: Hogan Jonathan J. , Weiss Brendan M.
Published: July 2016

The monoclonal gammopathies of renal significance (MGRS) are a group of disorders characterized by monoclonal Ig deposition in the kidney, but are not associated with systemic lymphoma or overt multiple myeloma. The prevailing hypothesis is that the pathogenic paraproteins in MGRS are produced by underlying B cell or plasma cell clones. However, in the MGRS literature, the yield of detecting a clone has been variable, and progression to ESRD is common. Here, we present an “onco-nephrologic” approach to the MGRS disorders by highlighting recent advances in lymphoma and multiple myeloma that can be used in the evaluation and management of these patients.

Communication-Based Cooperative Control Strategy for Public Transport Transfer Synchronization
Authors: Liu Tao , Ceder Avishai (Avi)
Published: July 2016

Synchronized transfers in public transport (PT) networks are used to reduce interroute or intermodal passenger transfer waiting time and to provide well-connected PT services. However, in practice, it is well known that synchronized transfers do not always occur because of stochastic and uncertain factors such as traffic disturbances and disruptions, fluctuations in passenger demand, and erroneous behavior on the part of PT drivers. This paper proposes a communication-based cooperative control (CCC) strategy, which has its basis in a library of selected operational tactics (e.g., skip stop or station, holding, changes in speed) to increase the actual occurrence of synchronized transfers and thus reduce average passenger transfer waiting time. The performance of the CCC strategy was compared with three other control strategies, namely, the without control strategy, the conventional schedule-based control strategy, and the communication-based noncooperative control strategy, according to various system performance indicators. A Monte Carlo method-based simulation procedure was developed to address the endogenous randomness in vehicle travel time, passenger demand, and driver behavior. The proposed methodology was applied to a detailed example network and in a case study in Auckland, New Zealand. The simulation and optimization results showed that, compared with the other three strategies, the CCC strategy performed best to increase the actual occurrence of planned synchronized transfers, reduce the average passenger transfer waiting time, and reduce the vehicle bunching percentage. Thus the CCC strategy shows great potential to increase the efficiency of PT networks, which involves synchronized transfers, and ultimately to improve the attractiveness of PT service.
Iterative forcing and hyperimmunity in reverse mathematics
Authors: Patey Ludovic
Published: July 2016

The separation between two theorems in reverse mathematics is usually done by constructing a Turing ideal satisfying a theorem P and avoiding the solutions to a fixed instance of a theorem Q. Lerman, Solomon and Towsner introduced a forcing technique for iterating a computable non-reducibility in order to separate theorems over omega-models. In this paper, we present a modularized version of their framework in terms of preservation of hyperimmunity and show that it is powerful enough to obtain the same separations results as Wang did with his notion of preservation of definitions. More than the actual separations, we provide a systematic method to design a computability-theoretic property which enables one to distinguish two statements, based on an analysis of their combinatorics.
Characterizing incentive compatible, Pareto optimal and sufficiently anonymous constrained combinatorial mechanisms – Two players case
Authors: Gonen Rica , Lerner Anat
Published: July 2016

We characterize the possibility space of deterministic, dominant-strategy incentive compatible, individually rational, and Pareto-optimal combinatorial auctions in a model with two players and two nonidentical items. Our model has multidimensional types, private values, quasilinear preferences for the players with one relaxation – one of the players is subject to a publicly-known budget constraint. We show that the space includes two types of mechanisms: VCG and dictatorial mechanisms. Furthermore when it is publicly known that the budgeted player is not constrained by his budget, VCG uniquely fulfills the basic properties of deterministic, dominant-strategy incentive compatible, individually rational, and Pareto-optimal. When it is publicly known that the budgeted player is constrained on all bundles then only a dictatorial solution will fulfill the above properties. Moreover when it is publicly known that the budgeted player is constrained on the largest bundle there are preferences under which the VCG mechanism uniquely fulfills these properties.
Beyond Diabetes: Does Obesity-Induced Oxidative Stress Drive the Aging Process?
Authors: Salmon Adam
Published: July 2016

Despite numerous correlative data, a causative role for oxidative stress in mammalian longevity has remained elusive. However, there is strong evidence that increased oxidative stress is associated with exacerbation of many diseases and pathologies that are also strongly related to advanced age. Obesity, or increased fat accumulation, is one of the most common chronic conditions worldwide and is associated with not only metabolic dysfunction but also increased levels of oxidative stress in vivo. Moreover, obesity is also associated with significantly increased risks of cardiovascular disease, neurological decline and cancer among many other diseases as well as a significantly increased risk of mortality. In this review, we investigate the possible interpretation that the increased incidence of these diseases in obesity may be due to chronic oxidative stress mediating segmental acceleration of the aging process. Understanding how obesity can alter cellular physiology beyond that directly related to metabolic function could open new therapeutic areas of approach to extend the period of healthy aging among people of all body composition.
Comparison of Ozone Production Regimes between Two Mexican Cities: Guadalajara and Mexico City
Authors: Kanda Isao , Basaldud Roberto , Magaña Miguel , Retama Armando , Kubo Ryushi , Wakamatsu Shinji
Published: July 2016

Ozone concentrations have been increasing in the Guadalajara Metropolitan Area (GMA) in Mexico. To help devise efficient mitigation measures, we investigated the ozone formation regime by a chemical transport model (CTM) system WRF-CMAQ. The CTM system was validated by field measurement data of ground-level volatile organic compounds (VOC) and vertical profiles of ozone in GMA as well as in the Mexico City Metropolitan Area (MCMA). By conducting CTM simulations with modified emission rates of VOC and nitrogen oxides (NOx), the ozone formation regime in GMA was found to lie between VOC-sensitive and NOx-sensitive regimes. The result is consistent with the relatively large VOC/NOx emission ratio in GMA compared to that in MCMA where the ozone formation regime is in the VOC-sensitive regime.
MIPs and Aptamers for Recognition of Proteins in Biomimetic Sensing
Authors: Menger Marcus , Yarman Aysu , Erdőssy Júlia , Yildiz Huseyin , Gyurcsányi Róbert , Scheller Frieder
Published: July 2016

Biomimetic binders and catalysts have been generated in order to substitute the biological pendants in separation techniques and bioanalysis. The two major approaches use either “evolution in the test tube” of nucleotides for the preparation of aptamers or total chemical synthesis for molecularly imprinted polymers (MIPs). The reproducible production of aptamers is a clear advantage, whilst the preparation of MIPs typically leads to a population of polymers with different binding sites. The realization of binding sites in the total bulk of the MIPs results in a higher binding capacity, however, on the expense of the accessibility and exchange rate. Furthermore, the readout of the bound analyte is easier for aptamers since the integration of signal generating labels is well established. On the other hand, the overall negative charge of the nucleotides makes aptamers prone to non-specific adsorption of positively charged constituents of the sample and the “biological” degradation of non-modified aptamers and ionic strength-dependent changes of conformation may be challenging in some application.
Aptasensors Based on Stripping Voltammetry

Published: July 2016

Aptasensors based on stripping voltammetry exhibit several advantages, such as high sensitivity and multi-target detection from stripping voltammetric technology, and high selectivity from the specific binding of apamers with targets. This review comprehensively discusses the recent accomplishments in signal amplification strategies based on nanomaterials, such as metal nanoparticles, semiconductor nanoparticles, and nanocomposite materials, which are detected by stripping voltammetry after suitable dissolution. Focus will be put in discussing multiple amplification strategies that are widely applied in aptasensors for small biomolecules, proteins, disease markers, and cancer cells.
Industrial Energy Consumption in Northeast China under the Revitalisation Strategy: A Decomposition and Policy Analysis
Authors: Li He , Lo Kevin , Wang Mark , Zhang Pingyu , Xue Longyi
Published: July 2016

While previous studies have examined China’s changing industrial energy consumption at the national level, this study argues that it is more useful, from a policy standpoint, to conduct a regional-level analysis owing to the significant regional disparity in industrialisation in the country. This study focuses particularly on Northeast China, where the implementation of the Northeast Revitalisation Strategy in 2003 has contributed to rapid reindustrialisation, which has a serious implication for industrial energy consumption. We decompose the region’s energy consumption changes into activity, structure, and intensity effects. Our results show that the intensity effect is not the only negative factor impacting industrial energy consumption during 2003–2012. The structure effect also has a negative impact on industrial energy consumption between 2005 and 2012. However, the negative impact of the two factors is weakening and not strong enough to counter the positive impact of the activity effect. This result highlights the problem of uncoordinated policy-making in Northeast China. The development strategy, which still depends highly on traditional heavy industries, is in conflict with the national strategy of energy conservation. The two conflicting objectives of industrial revitalization and energy conservation must be reconciled for sustainability in the long term. The study concludes with policy recommendations on how to achieve such reconciliation.
Willing to Be Involved in Cancer
Authors: Gunn-Moore Frank , Tilston-Lünel Andrew , Reynolds Paul
Published: July 2016

Genome sequencing is now a common procedure, but prior to this, screening experiments using protein baits was one of the routinely used methods that, occasionally, allowed the identification of new gene products. One such experiment uncovered the gene product called willin/human Expanded/FRMD6. Initial characterization studies found that willin bound phospholipids and was strongly co-localised with actin. However, subsequently, willin was found to be the closest human sequence homologue of the Drosophila protein Expanded (Ex), sharing 60% homology with the Ex FERM domain. This in turn suggested, and then was proven that willin could activate the Hippo signalling pathway. This review describes the increasing body of knowledge about the actions of willin in a number of cellular functions related to cancer. However, like many gene products involved in aspects of cell signalling, a convincing direct role for willin in cancer remains tantalisingly elusive, at present.

Yolŋu mathematics refers to the complex matrix of patterns, relationships, shapes, motions and rhythms of time and space that underpin the ways that Yolŋu people, Indigenous people of North East Arnhem Land in northern Australia, nourish and are nourished by their environments. Through its fundamental reliance on human and more-than-human connectivity and situatedness, Yolŋu people mobilise the concept of Yolŋu mathematics to challenge Western knowledges, including Western ideas of mathematics and environment. This paper discusses Yolŋu mathematics and the relationships between humans and more-than-humans, which co-produce a world that is living and interconnected, and which reveals all knowledge as situated.
River Basin Information System: Open Environmental Data Management for Research and Decision Making
Authors: Zander Franziska , Kralisch Sven
Published: July 2016

An open, standardized data management and related service infrastructure is a crucial requirement for a seamless storage and exchange of data and information within research projects, for the dissemination of project results and for their application in decision making processes. However, typical project databases often refer to only one research project and are limited to specific purposes. Once implemented, those systems are often not further maintained and updated, rendering the stored information useless once the system stops operating. The River Basin Information System (RBIS) presented here is designed to fit not only the requirements of one research project, but focuses on generic functions, extensibility and standards compliance typically found in interdisciplinary environmental research. Developed throughout more than 10 years of research cooperation worldwide, RBIS is designed to manage different types of environmental data with and without spatial context together with a rich set of metadata. Beside data management and storage, RBIS provides functions for the visualization, linking, analysis and processing of different types of data to support research, decision making, result dissemination and information discovery for all kinds of users. The focus of this paper is on the description of the technical implementation and the presentation of functions. This will be complemented by an overview of example applications and experiences during RBIS development and operation.
A Δ-9 Fatty Acid Desaturase Gene in the Microalga Myrmecia incisa Reisigl: Cloning and Functional Analysis
Authors: Xue Wen-Bin , Liu Fan , Sun Zheng , Zhou Zhi-Gang
Published: July 2016

The green alga Myrmecia incisa is one of the richest natural sources of arachidonic acid (ArA). To better understand the regulation of ArA biosynthesis in M. incisa, a novel gene putatively encoding the Δ9 fatty acid desaturase (FAD) was cloned and characterized for the first time. Rapid-amplification of cDNA ends (RACE) was employed to yield a full length cDNA designated as MiΔ9FAD, which is 2442 bp long in sequence. Comparing cDNA open reading frame (ORF) sequence to genomic sequence indicated that there are 8 introns interrupting the coding region. The deduced MiΔ9FAD protein is composed of 432 amino acids. It is soluble and localized in the chloroplast, as evidenced by the absence of transmembrane domains as well as the presence of a 61-amino acid chloroplast transit peptide. Multiple sequence alignment of amino acids revealed two conserved histidine-rich motifs, typical for Δ9 acyl-acyl carrier protein (ACP) desaturases. To determine the function of MiΔ9FAD, the gene was heterologously expressed in a Saccharomyces cerevisiae mutant strain with impaired desaturase activity. Results of GC-MS analysis indicated that MiΔ9FAD was able to restore the synthesis of monounsaturated fatty acids, generating palmitoleic acid and oleic acid through the addition of a double bond in the Δ9 position of palmitic acid and stearic acid, respectively.
Behavioral Abnormality Induced by Enhanced Hypothalamo-Pituitary-Adrenocortical Axis Activity under Dietary Zinc Deficiency and Its Usefulness as a Model
Authors: Takeda Atsushi , Tamano Haruna , Nishio Ryusuke , Murakami Taku
Published: July 2016

Dietary zinc deficiency increases glucocorticoid secretion from the adrenal cortex via enhanced hypothalamo-pituitary-adrenocortical (HPA) axis activity and induces neuropsychological symptoms, i.e., behavioral abnormality. Behavioral abnormality is due to the increase in glucocorticoid secretion rather than disturbance of brain zinc homeostasis, which occurs after the increase in glucocorticoid secretion. A major target of glucocorticoids is the hippocampus and their actions are often associated with disturbance of glutamatergic neurotransmission, which may be linked to behavioral abnormality, such as depressive symptoms and aggressive behavior under zinc deficiency. Glucocorticoid-mediated disturbance of glutamatergic neurotransmission in the hippocampus is also involved in the pathophysiology of, not only psychiatric disorders, such as depression, but also neurodegenerative disorders, e.g., Alzheimer’s disease. The evidence suggests that zinc-deficient animals are models for behavioral and psychological symptoms of dementia (BPSD), as well as depression. To understand validity to apply zinc-deficient animals as a behavioral abnormality model, this paper deals with the effect of antidepressive drugs and herbal medicines on hippocampal dysfunctions and behavioral abnormality, which are induced by enhanced HPA axis activity under dietary zinc deficiency.
Predicting Fluid Intelligence by Components of Reaction Time Distributions from Simple Choice Reaction Time Tasks
Authors: Schulz-Zhecheva Yoanna , Voelkle Manuel , Beauducel André , Biscaldi Monica , Klein Christoph
Published: July 2016

Mean reaction times (RT) and the intra-subject variability of RT in simple RT tasks have been shown to predict higher-order cognitive abilities measured with psychometric intelligence tests. To further explore this relationship and to examine its generalizability to a sub-adult-aged sample, we administered different choice RT tasks and Cattell’s Culture Fair Intelligence Test (CFT 20-R) to n = 362 participants aged eight to 18 years. The parameters derived from applying Ratcliff’s diffusion model and an ex-Gaussian model to age-residualized RT data were used to predict fluid intelligence using structural equation models. The drift rate parameter of the diffusion model, as well as σ of the ex-Gaussian model, showed substantial predictive validity regarding fluid intelligence. Our findings demonstrate that stability of performance, more than its mere speed, is relevant for fluid intelligence and we challenge the universality of the worst performance rule observed in adult samples.
An NMR-Guided Screening Method for Selective Fragment Docking and Synthesis of a Warhead Inhibitor

Published: July 2016

Selective hits for the glutaredoxin ortholog of Brucella melitensis are determined using STD NMR and verified by trNOE and 15N-HSQC titration. The most promising hit, RK207, was docked into the target molecule using a scoring function to compare simulated poses to experimental data. After elucidating possible poses, the hit was further optimized into the lead compound by extension with an electrophilic acrylamide warhead. We believe that focusing on selectivity in this early stage of drug discovery will limit cross-reactivity that might occur with the human ortholog as the lead compound is optimized. Kinetics studies revealed that lead compound 5 modified with an ester group results in higher reactivity than an acrylamide control; however, after modification this compound shows little selectivity for bacterial protein versus the human ortholog. In contrast, hydrolysis of compound 5 to the acid form results in a decrease in the activity of the compound. Together these results suggest that more optimization is warranted for this simple chemical scaffold, and opens the door for discovery of drugs targeted against glutaredoxin proteins—a heretofore untapped reservoir for antibiotic agents.
Applications of 19F-NMR in Fragment-Based Drug Discovery
Authors: Norton Raymond , Leung Eleanor , Chandrashekaran Indu , MacRaild Christopher
Published: July 2016

19F-NMR has proved to be a valuable tool in fragment-based drug discovery. Its applications include screening libraries of fluorinated fragments, assessing competition among elaborated fragments and identifying the binding poses of promising hits. By observing fluorine in both the ligand and the target protein, useful information can be obtained on not only the binding pose but also the dynamics of ligand-protein interactions. These applications of 19F-NMR will be illustrated in this review with studies from our fragment-based drug discovery campaigns against protein targets in parasitic and infectious diseases.

Published: July 2016

A high-yield one-pot two-step synthesis of 2-aminoimidazoles (2-AI), exploiting an under-air heterocyclodehydration process between α-chloroketones and guanidine derivatives, and using deep eutectic solvents (DESs) as nonconventional, “green” and “innocent” reaction media, has been accomplished successfully. The combination of either glycerol or urea with choline chloride (ChCl) proved to be effective for decreasing the reaction time to about 4–6 h in contrast to the 10–12 h usually required for the same reaction run in toxic and volatile organic solvents and under an argon atmosphere. In addition, the use of the ChCl–urea as a DES also enables the direct isolation of triaryl-substituted 2-AI derivatives by means of a simple work-up procedure consisting in filtration and crystallization, and allows the recycle of the DES mixture. A plausible mechanism highlighting the potential role played by hydrogen bonding catalysis has also been illustrated.
Publishing Patterns in BRIC Countries: A Network Analysis
Authors: Guevara Miguel , Mendoza Marcelo
Published: July 2016

How similar are the publishing patterns of among Brazil, Russia, India and China (BRIC countries) in comparison with other countries? This is a question that we addressed by using networks as a tool to analyze the structure of similarities and disparities between countries. We analyzed the number of publications from 2006 to 2015 that are reported by SCImago Journal and Country Rank. With this information, we created a network in order to find the closest countries to BRIC ones, and also to find communities of similar countries favoring data analysis. We found that Brazil, China and Russia are not that close to the core cluster of countries that are more diversified. In opposition, India is closer to a community of countries that are more diverse in terms of publishing patterns. Furthermore, we found that, for different network topologies, Brazil acts as a bridge to connect developing countries and that Russia practices patterns that tend to isolate it from most of the countries.
Coal Mining Waste as a Future Eco-Efficient Supplementary Cementing Material: Scientific Aspects
Authors: Frías Moisés , García Rosario , Vigil de la Villa Raquel , Martínez-Ramírez Sagrario
Published: July 2016

The stockpiling of tailings around coal mines poses a major environmental problem. Nonetheless, this clay mineral (kaolinite)-based waste can be reused as a supplementary cementitious material (recycled metakaolinite) in the manufacture of future eco-efficient cements. This paper explores the most significant scientific questions posed in connection with the conversion of this waste into pozzolans, such as the variation in product mineralogy depending on the sintering temperature and its effect on reaction kinetics in the pozzolan/Ca(OH)2 system over a period of 365 days. The findings show that the optimal sintering temperature is 600 °C, such that the cementitious properties of the activated product are determined solely by the conversion of kaolinite into metakaolinite and are unaffected by the other clay minerals (micas). The presence of 20% activated coal waste favors the formation of larger amounts of aluminous phases such as C4AH13 and C4AcH12 than in the reference paste and enhances C–S–H gel polymerization.
The Enlightened Self: Identity and Aspiration in Two Communities of Practice
Authors: Johnston Erin
Published: July 2016

Existing research on religious identity, especially from a narrative perspective, has tended to focus either on accounts of the past (especially occasions of religious change) or on conceptions of religious identity in the present. Religious communities, however, not only provide a sense of identity and belonging in the present—as a “Catholic” or “Buddhist,” for example—they also promote a particular vision of the religious ideal: The way of being-in-the-world that all adherents are (or ought to be) striving to achieve. Drawing on fieldwork and interviews, this paper describes and analyzes the identity and lifestyle goals of participants in two communities of practice: An Integral Yoga studio and a Catholic prayer house. I find that the ideal spiritual self in both communities is defined by three key characteristics: A sacred gaze, a simultaneous sense of presence and detachment, and a holistic style of identity management. I suggest that in constructing and transmitting a shared vision of the “enlightened self,” these organizations offer practitioners a highly desirable but ever-elusive aspirational identity. This study calls attention to religious organizations as important suppliers of possible identities—the identities, either desired and feared, we think we could or might become in the future—and reveals the situated and contextual nature of adherents’ religious aspirations.
The Use of Aerial RGB Imagery and LIDAR in Comparing Ecological Habitats and Geomorphic Features on a Natural versus Man-Made Barrier Island
Authors: Anderson Carlton , Carter Gregory , Funderburk William
Published: July 2016

The Mississippi (MS) barrier island chain along the northern Gulf of Mexico coastline is subject to rapid changes in habitat, geomorphology and elevation by natural and anthropogenic disturbances. The purpose of this study was to compare habitat type coverage with respective elevation, geomorphic features and short-term change between the naturally-formed East Ship Island and the man-made Sand Island. Ground surveys, multi-year remotely-sensed data, habitat classifications and digital elevation models were used to quantify short-term habitat and geomorphic change, as well as to examine the relationships between habitat types and micro-elevation. Habitat types and species composition were the same on both islands with the exception of the algal flat existing on the lower elevated spits of East Ship. Both islands displayed common patterns of vegetation succession and ranges of existence in elevation. Additionally, both islands showed similar geomorphic features, such as fore and back dunes and ponds. Storm impacts had the most profound effects on vegetation and geomorphic features throughout the study period. Although vastly different in age, these two islands show remarkable commonalities among the traits investigated. In comparison to East Ship, Sand Island exhibits key characteristics of a natural barrier island in terms of its vegetated habitats, geomorphic features and response to storm impacts, although it was established anthropogenically only decades ago.
A Low Collision and High Throughput Data Collection Mechanism for Large-Scale Super Dense Wireless Sensor Networks
Authors: Lei Chunyang , Bie Hongxia , Fang Gengfa , Gaura Elena , Brusey James , Zhang Xuekun , Dutkiewicz Eryk
Published: July 2016

Super dense wireless sensor networks (WSNs) have become popular with the development of Internet of Things (IoT), Machine-to-Machine (M2M) communications and Vehicular-to-Vehicular (V2V) networks. While highly-dense wireless networks provide efficient and sustainable solutions to collect precise environmental information, a new channel access scheme is needed to solve the channel collision problem caused by the large number of competing nodes accessing the channel simultaneously. In this paper, we propose a space-time random access method based on a directional data transmission strategy, by which collisions in the wireless channel are significantly decreased and channel utility efficiency is greatly enhanced. Simulation results show that our proposed method can decrease the packet loss rate to less than 2 % in large scale WSNs and in comparison with other channel access schemes for WSNs, the average network throughput can be doubled.
Effect of Land Use and Cover Change on Air Quality in Urban Sprawl
Authors: Zou Bin , Xu Shan , Sternberg Troy , Fang Xin
Published: July 2016

Due to the frequent urban air pollution episodes worldwide recently, decision-makers and government agencies are struggling for sustainable strategies to optimize urban land use/cover change (LUCC) and improve the air quality. This study, thus, aims to identify the underlying relationships between PM10 concentration variations and LUCC based on the simulated PM10 surfaces in 2006 and 2013 in the Changsha-Zhuzhou-Xiangtan agglomeration (CZT), using a regression modeling approach. LUCC variables and associated landscape indexes are developed and correlated with PM10 concentration variations at grid level. Results reveal that the overall mean PM10 concentrations in the CZT declined from 106.74 μg/m3 to 94.37 μg/m3 between 2006 and 2013. Generally, variations of PM10 concentrations are positively correlated with the increasing built-up area, and negatively correlated with the increase in forests. In newly-developed built-up areas, PM10 concentrations declined with the increment of the landscape shape index and the Shannon diversity index and increased with the growing Aggregation index and Contagion index. In other areas, however, the reverse happens. These results suggest that LUCC caused by urban sprawl might be an important factor for the PM10 concentration variation in the CZT. The influence of the landscape pattern on PM10 concentration may vary in different stages of urban development.
Assessing Urban Forest Structure, Ecosystem Services, and Economic Benefits on Vacant Land
Authors: Kim Gunwoo
Published: July 2016

An urban forest assessment is essential for developing a baseline from which to measure changes and trends. The most precise way to assess urban forests is to measure and record every tree on a site, but although this may work well for relatively small populations (e.g., street trees, small parks), it is prohibitively expensive for large tree populations. Thus, random sampling offers a cost-effective way to assess urban forest structure and the associated ecosystem services for large-scale assessments. The methodology applied to assess ecosystem services in this study can also be used to assess the ecosystem services provided by vacant land in other urban contexts and improve urban forest policies, planning, and the management of vacant land. The study’s findings support the inclusion of trees on vacant land and contribute to a new vision of vacant land as a valuable ecological resource by demonstrating how green infrastructure can be used to enhance ecosystem health and promote a better quality of life for city residents.
Mapping Protein–Protein Interactions of the Resistance-Related Bacterial Zeta Toxin–Epsilon Antitoxin Complex (ε2ζ2) with High Affinity Peptide Ligands Using Fluorescence Polarization

Published: July 2016

Toxin–antitoxin systems constitute a native survival strategy of pathogenic bacteria and thus are potential targets of antibiotic drugs. Here, we target the Zeta–Epsilon toxin–antitoxin system, which is responsible for the stable maintenance of certain multiresistance plasmids in Gram-positive bacteria. Peptide ligands were designed on the basis of the ε2ζ2 complex. Three α helices of Zeta forming the protein–protein interaction (PPI) site were selected and peptides were designed conserving the residues interacting with Epsilon antitoxin while substituting residues binding intramolecularly to other parts of Zeta. Designed peptides were synthesized with an N-terminal fluoresceinyl-carboxy-residue for binding assays and provided active ligands, which were used to define the hot spots of the ε2ζ2 complex. Further shortening and modification of the binding peptides provided ligands with affinities <100 nM, allowing us to determine the most relevant PPIs and implement a robust competition binding assay.

Authors: Gomez Florent , Hostein Bernard
Published: July 2016

The professional paper is often adequated with a research work irrelevant to the reality of the training. The professional paper can be considered in a different way, that is to say as a realisation of the project underlying the trainee teacher's action ; thus considered, the task of producing a professional paper helps develop the abilities which characterize a "reflective practitioner". By seeking to achieve the balance between action, assessment and writing, one aims to build up adjustments in and for the teaching practice.
Le mémoire professionnel IUFM est-il professionnalisant ?
Authors: Fabre Michel , Lang Vincent
Published: July 2016

By the standards of a narrow model of professionalization based on the developpment of technical or clinical skills, the professionalizing nature of the professional dissertation appears as problematical. One cannot establish a measurable effect of the professional dissertation on the teaching skills, the ability to form personal ethics or to integrate scientific knowledge. But is this possible with the other training systems ? If one adopts a wider view of the process of professionalization including the search for identity and the professional affiliation, the tensions induced by the conceptions of the professional dissertation and the training systems that go with it, become more understandable. However, one cannot assert clearly that the professional dissertation plays a decisive role in the professional socialization of beginners. One must therefore object to the illusions of militants as mush as to the denunciations of detractors : the professional disseration proves to be an opportunity to professionalize which the trainees must seize, even if it is more or less rich depending on the site, the training systems and the training models. The professional dissertation could become more professionalizing if it were conceided as a pedagogical reasoning and thinking with their specificity and requirements.
La liste de diffusion électronique, un instrument de formation professionnelle ?
Authors: Audran Jacques
Published: July 2016

"Broadcasting lists" are developing quite rapidly on the Internet and the teachers who suscribe to a professional list of education, whether it is based on a theme or a subject matter, are becoming more and more numerous. It appears that these lists are places which are both favourable to an exchange of information and also to debates between members. This paper is drawn from a research concerning the practices and conceptions of the primary school teachers who have chosen to create a Website within the context of their
Diagnostic kinésithérapique : les conditions d’une coproduction
Authors: Olry Paul , Rothier-Bautzer Eliane
Published: July 2016

L’article propose une première analyse des conditions de production du diagnostic kinésithérapique. L’approche montre que la perception que le kinésithérapeute se fait du soin qu’il réalise est fondée sur l’imbrication des étapes de diagnostic et de soin. Les auteurs soulignent que cela s’accompagne d’un processus paradoxal de coproduction du soin qui requiert à la fois la participation «active » du patient et l’objectivation de son corps soumis aux manipulations du soignant.
L’efficacité des dispositifs d’aide aux étudiants dans les universités
Authors: Michaut Christophe
Published: July 2016

Ces deux dernières décennies, les universités ont mis en place des dispositifs d’aide aux étudiants en difficulté scolaire (tutorat, remises à niveaux, enseignements méthodologiques). Certains de ces dispositifs ont vu le jour à partir d’initiatives locales, d’autres ont été institutionnalisés sans que l’on s’interroge véritablement sur leur efficacité pédagogique et encore moins sur leur efficience. Dans quelle mesure de tels dispositifs améliorent-ils significativement les résultats des étudiants ? Après une revue des travaux existant sur cette question, cet article présentera, à titre d’exemple, les résultats d’une recherche examinant, entre autres, l’impact du tutorat sur la réussite en première année de DEUG dans trois filières (AES, Psychologie, Sciences de la vie) et trois universités (Dijon, Nantes, Toulouse). 1 763 étudiants ont été interrogés en cours d’année, notamment sur leurs pratiques d’études, et leurs résultats aux examens ont été recueillis. La comparaison des résultats obtenus par les étudiants fréquentant le tutorat d’accompagnement par rapport à ceux qui n’y assistent pas montre, toutes choses égales par ailleurs, que les écarts ne sont pas significatifs.
The hydrolysis of geminal ethers: a kinetic appraisal of orthoesters and ketals
Authors: Repetto Sonia L , Costello James F , Butts Craig P , Lam Joseph K W , Ratcliffe Norman M
Published: July 2016

A novel approach to protecting jet fuel against the effects of water contamination is predicated upon the coupling of the rapid hydrolysis reactions of lipophilic cyclic geminal ethers, with the concomitant production of a hydrophilic acyclic hydroxyester with de-icing properties (Fuel Dehydrating Icing Inhibitors - FDII). To this end, a kinetic appraisal of the hydrolysis reactions of representative geminal ethers was undertaken using a convenient surrogate for the fuel–water interface (D2O/CD3CN 1:4). We present here a library of acyclic and five/six-membered cyclic geminal ethers arranged according to their hydroxonium catalytic coefficients for hydrolysis, providing for the first time a framework for the development of FDII. A combination of1H NMR, labelling and computational studies was used to assess the effects that may govern the observed relative rates of hydrolyses.
Species composition, community and population dynamics of two gallery forests from the Brazilian Cerrado domain

Published: July 2016

To understand the impacts of global changes on future community compositions, knowledge of community dynamics is of crucial importance. To improve our knowledge of community composition, biomass stock and maintenance of gallery forests in the Brazilian Cerrado, we provide two datasets from the 0.5 ha Corrego Fazendinha Gallery Forest Dynamics Plot and the Corrego Fundo Gallery Forest Dynamics Plot situated in the Bom Despacho region, Minas Gerais, Southeastern Brazil.

We report diameter at breast height, basal area and height measurements of 3417 trees and treelets identified during three censuses in both areas.
Bibliometric study to assist research topic selection: a case from research design on Jakarta’s groundwater (part 1)

Published: July 2016

This paper is an example to visualize bibliometric data to extract paper’s topics and their citation relation. It is very important to evaluate the number of documents, the intensity of the paper’s topic, and the relationship between papers. The output can be used to pinpoint suitable research topic.

We began with 246 papers, gathered from Google Scholar, Crossref, and Scopus database. We narrowed them down to 70 papers based on language, relevance, pdf availability, and metadata completeness. Open source tools, Vosviewer, Zotero-PaperMachine plugin, were used to visualize the existing reference database.

The following paper gives an illustration that a brief bibliometric analysis could assist a researcher to determine our research path. It gives us a glimpse of research landscape in Jakarta area. Therefore for deeper analysis, we will focus our literature review on groundwater and surface water interactions.

Arquitectura troglodítica durante el siglo XX en Almería
Authors: Cachorro Fernández Emilio
Published: July 2016

Los escasos estudios sobre vivienda moderna y contemporánea en la provincia de Almería han centrado su interés en los más brillantes desarrollos urbanísticos y edificatorios, haciendo sombra a otros episodios habitacionales sin los que la realidad local se percibe equívoca e incompleta, como es el caso de la arquitectura subterránea, lo que reclama profundizar en su evolución y alcance durante el último siglo. La metodología empleada se ha basado en la consulta de censos, inventarios, registros, crónicas periodísticas, expedientes de Administraciones Públicas, Asociaciones de Desarrollo Rural y otras organizaciones, además del reconocimiento de campo con un muestreo suficientemente representativo de visitas y entrevistas. Así, tras contextualizar el fenómeno, los resultados obtenidos permiten deducir tanto su relevancia territorial y social como el cambio lento, pero progresivo, de consideración en décadas recientes, a favor de un hábitat que se ha reivindicado como parte intrínseca del patrimonio y la herencia cultural.
