Published: November 2016

The northern Tibetan Plateau is the most traditional and important semi-nomadic region in Tibet. The alpine vegetation is sensitive and vulnerable to climate change and human activities, and is also important as an ecological security in protecting the headwaters of major rivers in Asia. Therefore, the Tibetan alpine grasslands have fundamental significance to both Mainland China and South Asia. The pasture degradation, however, likely threatens the livelihood of residents and the habitats of wildlife on this plateau. Since 2004, the government has launched a series of ecological restoration projects and economic compensatory payment polices. Many fences were additionally built on degraded pastures to prevent new degradation, to promote functionality recovery, and to balance the stocking rate with forage productivity. The grazed vs. fenced paired pastures across different zonal grassland communities along evident environmental gradients provide us with a natural comparative experiment platform to test the relative contributions of natural and anthropogenic factors. This study critically reviews the background, significance of and debates on short-term grazing exclusion with fences in this region. We also aim to figure out scientific and standardized workflows for assessing the effectiveness of grazing exclusion and compensatory payments in the future.

Published: November 2016

Duck Tembusu virus (DTMUV) causes substantial egg drop disease. DTMUV was first identified in China and rapidly spread to Malaysia and Thailand. The antigenicity of the DTMUV E protein has not yet been characterized. Here, we investigated antigenic sites on the E protein using the non-neutralizing monoclonal antibodies (mAbs) 1F3 and 1A5. Two minimal epitopes were mapped to 221LD/NLPW225 and 87YAEYI91 by using phage display and mutagenesis. DTMUV-positive duck sera reacted with the epitopes, thus indicating the importance of the minimal amino acids of the epitopes for antibody-epitope binding. The performance of the dot blotting assay with the corresponding positive sera indicated that YAEYI was DTMUV type-specific, whereas 221LD/NLPW225 was a cross-reactive epitope for West Nile virus (WNV), dengue virus (DENV), and Japanese encephalitis virus (JEV) and corresponded to conserved and variable amino acid sequences among these strains. The structure model of the E protein revealed that YAEYI and LD/NLPW were located on domain (D) II, which confirmed that DII might contain a type-specific non-neutralizing epitope. The YAEYI epitope-based antigen demonstrated its diagnostic potential by reacting with high specificity to serum samples obtained from DTMUV-infected ducks. Based on these observations, a YAEYI-based serological test could be used for DTMUV surveillance and could differentiate DTMUV infections from JEV or WNV infections. These findings provide new insights into the organization of epitopes on flavivirus E proteins that might be valuable for the development of epitope-based serological diagnostic tests for DTMUV.

Published: November 2016

Results of the luge athletes strongly depend on the successful start. While number of
methods successfully analysed movements around start handles, still there is lack of methods to
monitor paddling strokes. Present paper demonstrates smart textile gloves, designed for such a
purpose. Developed gloves allow to measure timing of the arms strokes as well as easily
distinguish between good stroke, when athlete’s palms are in full contact with ice, and insufficient
one, when fingers just slide over ice without providing good push.

Published: November 2016

In this work we aim to determine the mechanical properties of 3D printed PLA objects
having various orientation woodpile microarchitectures. In this work we chose three different 3D
microarchitectures: woodpile BCC (each layer consists of parallel logs which are rotated 90 deg
every next layer), woodpile FCC (every layer is additionally shifted half of the period in respect
to the previous parallel log layer) and a rotating woodpile 60 deg (each layer is rotated 60 deg in
respect to the previous one). Compressive and bending tests were carried out TIRAtest2300
universal testing machine. We found that 60 deg rotating woodpile geometry had the highest
values which was approximately 3 times than the BCC or FCC log arrangements. Thus we prove
that employing low-cost equipment and applying the same raw material one can create objects of
desired rigidity.
Numerical modelling of the forklift tip-over to test effectiveness of the safety components
Authors: Milanowicz Marcin , Budziszewski Paweł , Kędzior Krzysztof
Published: November 2016

Forklift overturning with its operator is the most common and dangerous type of an
accident involving internal transport. The forklifts are equipped with safety components to avoid,
or reduce the effects of forklift tip-over. However, there is very few information on the
effectiveness of such systems. The aim of the research was to evaluate their effectiveness with the
use of numerical simulation. The study relied on carrying out numerical simulations of forklift
overturning with its operator. Active human body model was used in the research. Human body
output parameters, e.g. forces and accelerations of the head and neck were used to estimate injuries
sustained by an operator. The effectiveness of the safety components was assessed on the basis of
estimated injuries.
Myotonometry as a tool for determination of fatigue in the upper extremities of garment industry workers
Authors: Pille Viive , Tint Piia
Published: November 2016

The myotonometric measurements of upper limb muscles of garment workers working
in a static posture are presented. The workers’ pain intensity was followed on the pain Visual
Analogue Scale. The results show that M trapezius and other spine muscles differ at the beginning
and the end of the workweek. In hand muscles, the difference is not so significant. The load
accumulates in the hands over the years, and the spine and neck get tired more quickly; therefore,
there are more complaints of pain in the neck and back. The values of measured stiffness of the
muscles was between 156–278 N/m and for the own frequency of muscles 11.2–16.5 Hz.

Interior Design of Care Homes for People with Alzheimer's Disease: A Comparative Study
Authors: Krliu Tina
Published: November 2016

BACKGROUND: The population of people with Alzheimer’s disease (AD) is rapidly increasing worldwide. While in Republic of Macedonia there is no formal special care for people with AD, developed countries are expanding on both the typology of their care homes and services they offer for people with AD. The Macedonian aging population is in need of long-term care (LTC) options tailored to meet the special needs of people with AD.AIM: The aims of this study are (i) to explore the Macedonian approach to the problem of creating LTC environments for people with AD, as compared to the approach of a developed country through the example of Canada, and (ii) to identify successful interior design characteristics that would meet the special needs of people with AD. METHODS: The study begins by reviewing existing literature with the purpose of obtaining knowledge about the common clinical symptoms of AD (i.e. memory problems and behavior) and how these changes have an impact on the interaction between AD individuals and the physical environment they live in. For the purposes of the study, a fieldtrip was conducted in two LTC homes in Toronto (Canada) offering special 24 hour care for people with AD, and one LTC home in Skopje (Macedonia) that includes people with AD in their care program. The interior design of LTC homes was described through photographs, plans, observations and a description of the spaces used by people with AD. For a controlled analysis of the recorded environments, the 'Evaluation of Older People's Living Environments (EVOLVE)' questionnaire was used. RESULTS: The identified qualities from the case studies, and the lessons learned throughout the analysis of the key design elements, were used towards developing a list of suggestions for modifying the interior of the Macedonian LTC home. The developed suggestions were classified into two groups: (1) proposals for minimal constructional modifications of the interior environment, and (2) proposals for major constructional modifications of the interior environment. CONCLUSION: While the suggested modifications are not final changes of the LTC environment, they are an important step towards developing a design strategy for providing 24 hour care for people with AD in Macedonia.
Fumonisins and their modified forms, a matter of concern in future scenario?
Authors: Dall’Asta C. , Battilani P.
Published: November 2016

Masked mycotoxins are found in grains and derived foods as a result of plant phase II metabolism. Recently, masked mycotoxinssenso strictu, together with other covalently or non-covalently conjugated forms, even formed upon processing, have been classified as modified mycotoxins. In this context, the issue of modified fumonisins is of great interest, on account of the wide range of factors affecting their formation and accumulation in maize pre- and postharvest. Fumonisins, indeed, may undergo modification in plants, along the growing season, but also during storage and drying of maize kernels, and upon processing. All these modifications strongly affect the analytical outcome, thus making more difficult the assessment of maize compliance. Since the ratio between free and modified fumonisins is affected by maize composition and environmental factors, a deeper knowledge on the phenomena driving the production and accumulation of free and modified forms in plants may support the selection of resistant hybrids. This review provides a critical picture of the state of the art on this topic, mainly focusing on those events occurring in field, identified as crucial in determining amount and partitioning of contamination. Nevertheless, knowledge on modified fumonisins is still in its dawn, on account of the wide range of factors involved. Anyway, reported results, taking altogether, clearly indicate that modified fumonisins should be included in the monitoring plans to have an overview of the possible contribution to human exposure. Furthermore, next efforts should focus on the events occurring in field and on the cross-talk between the plant and the fungus, to support the identification of resistant hybrids and to provide data for predictive models, the most suitable tool to forecast what is going to happens in the future changing climate.
La géographie, émergence d’un champ scientifique
Authors: Péaud Laura
Published: November 2016

Cet ouvrage interroge le moment où, entre 1780 et 1860, la géographie se structure en champ scientifique et académique indépendant en Europe, et particulièrement en France, en Prusse et en Grande-Bretagne. Au même moment dans ces trois pays, des géographes travaillent à ce que leur champ d’étude soit enfin considéré comme une science à part entière.

Ce processus de construction à la fois scientifique et disciplinaire est profondément marqué par l’héritage des Lumières et l’esprit universaliste, mais, parallèlement, il se trouve également influencé et informé par le contexte politique. Les savoirs géographiques sont en effet investis d’une valeur stratégique grandissante : ils jouent un rôle majeur dans les idéologies et actions politiques des États.

Par le croisement de sources de différentes natures, par l’articulation d’une approche internaliste et externaliste, ce livre s’inscrit dans le champ du spatial turn.
Three-Dimensional Information Retrieval (3DIR)
Authors: Demian Peter , Ruikar Kirti , Sahu Tarun , Morris Anne
Published: November 2016

An increasing amount of information is packed into BIMs, with the 3D geometry serving as a central index leading to other information. The 3DIR project investigates information retrieval from such environments. Here, the 3D visualization can be exploited when formulating queries, computing the relevance of information items, or visualizing search results. The need for such a system was specified using workshops with end users. A prototype was built on a commercial BIM platform. Following an evaluation, the system was enhanced to exploit model topology. Relationships between 3D objects are used to widen the search, whereby relevant information items linked to a related 3D object (rather than linked directly to objects selected by the user) are still retrieved but ranked lower. An evaluation of the enhanced prototype demonstrates its effectiveness but highlights its added complexity. Care needs to be taken when exploiting topological relationships, but that a tight coupling between text-based retrieval and the 3D model is generally effective in information retrieval from BIMs.

This study aimed to explore the effectiveness of a Kinect-based game called Tom Clancy's Ghost Recon: Future Soldier to investigate possible contributions of game-based learning in a virtual language classroom at a state university in Ankara, Turkey. A quasi-experimental design where the treatment group (N= 26) was subjected to kinect-based learning environments, and the control group (N = 26) continued with traditional learning environments was used. All the participants were administered an achievement test as a pre-test, and a post-test. Moreover, the qualitative part of the study included post-study semi-structured interviews with 10 students. The findings showed that there was significant mean difference in student achievement in post-test scores in favor of the experimental group. In addition, the study explored the opinions of the students toward the use of gesture-based computing systems for instructional purposes.The findings suggested some important points to consider while making use of kinect-based games for educational purposes like interaction and learner motivation.
LEAP Enhanced
Authors: Yassine Maleh , Ezzati Abdellah
Published: November 2016

Wireless Sensor Network (WSN) is consisting of independent and distributed sensors to monitor physical or environmental conditions, such as temperature, sound, pressure, etc. The most crucial and fundamental challenge facing WSN is security. Due to minimum capacity in-term of memory cost, processing and physical accessibility to sensors devices the security attacks are problematic. They are mostly deployed in open area, which expose them to different kinds of attacks. In this paper, the authors present an illustration of different attacks and vulnerabilities in WSN. Then the authors proposed a new lightweight cryptography algorithm for identifying compromised node in WSN called Leap Enhanced. Their evaluations on TOSSIM give a precise and detailed idea of the extra cost of consumption of resources needed to ensure the high level of expected security compared to other cryptography schemes in literature.

Authors: Saowapark Thanunya , Chaichana Ekrachan , Jaturapiree Adisak
Published: November 2016

Molasses is an inexpensive byproduct made during the extraction of sugars from sugarcane. Viscous molasses was converted to powder form under heating process. Molasses black (MB), mainly consisting of carbon, was finally obtained. As a result of elemental analyzer, it is evident that MB containing 56.13 % of carbon. Additionally, Fourier Transform Infrared Spectrophotometer (FTIR) result confirmed that function groups of MB were comparable with carbon black (CB). Nevertheless, the large particle size and low specific surface area of MB was less effective for reinforcement. Therefore, in this research, a feasibility study was carried out on the utilization of MB together with carbon black as hybrid filler in natural rubber (NR). Reinforcement of NR with MB/CB hybrid filler at various ratios was studied. The total hybrid filler content was 30 parts per hundred of rubber (phr). The mechanical properties were determined. The results revealed that the NR vulcanizates containing hybrid filler exhibited the better reinforcement than that filled with single MB filler.
The Interrelationship of Common Clinical Movement Screens: Establishing Population-Specific Norms in a Large Cohort of Military Applicants
Authors: de la Motte Sarah J. , Gribbin Timothy C. , Lisman Peter , Beutler Anthony I. , Deuster Patricia
Published: November 2016

Context: Musculoskeletal injuries (MSK-Is) are a leading cause of missed duty time and morbidity in the military. Modifiable risk factors for MSK-Is, such as inadequate core stability, poor movement patterns, and dynamic balance deficits, have not been identified in military applicants on entering service.

Objective: To establish normative functional movement data using a series of screens in military applicants entering basic training and explore relationships among several movement tests.

Design: Cross-sectional study.

Setting: Military Entrance Processing Station.

Patients or Other Participants: A total of 1714 (1434 male, 280 female) military applicants entering the US Army (n = 546), Navy (n = 414), Air Force (n = 229), or Marine Corps (n = 525).

Intervention(s): We conducted the Functional Movement Screen (FMS), Y-Balance Test (YBT), overhead squat (OHS), and Landing Error Scoring System (LESS). Movements were assessed using the scoring convention for each screen.

Main Outcome Measure(s): The FMS, YBT, OHS, and LESS scores and associations among the movement screens as well as clinical meaningfulness.

Results: A total of 1037 of the 1714 enrolled applicants were screened on the day they left for basic training. Normative means for this population were established: FMS = 14.7 ± 1.8, YBT anterior-reach difference = 3.1 ± 3.0 cm, mean YBT composite differences = 8.0 ± 6.8 cm, mean YBT composite percentage = 90.9% ± 8.3%, OHS errors = 5.0 ± 2.8, and LESS score = 5.7 ± 2.1. Backward regression results revealed that the YBT composite percentage was related to the FMS and OHS scores in males and to the FMS and LESS results in females. However, clinically meaningful relationships between the tests varied for both males and females.

Conclusions: Sex-normative values for the FMS, YBT, OHS, and LESS screens were established for US military applicants, and some of the assessments overlapped. Overall, males performed better on the OHS and LESS and achieved a greater YBT composite percentage than females. The regression results revealed movement screen performance relationships that varied by sex and clinical meaningfulness. In future studies, we will determine if performance on any of the screens is associated with MSK-Is in basic trainees.

Abstract. This paper presents an exploratory study on the retrieval of aerosol layer height (ALH) from the OMI 477 nm O2–O2 spectral band. We have developed algorithms based on the Multilayer Perceptron (MLP) Neural Network (NN) approach and applied them on 3-year (2005–2007) OMI cloud-free scenes over North-East Asia, collocated with MODIS-Aqua aerosol product. In addition to the importance of aerosol altitude for climate and air quality objectives, the main motivation of this study is to evaluate the possibility of retrieving ALH for potential future improvements of trace gas retrievals (e.g. NO2, HCHO, SO2, etc..) from UV-Vis air quality satellite measurements over scenes including high aerosol concentrations. ALH retrieval relies on the analysis of the O2–O2 slant column density (SCD) and requires an accurate knowledge of the aerosol optical thickness τ. Using the MODIS-Aqua aerosol optical thickness at 550 nm as a prior information, comparison with the LIdar climatology of vertical Aerosol Structure for space-based lidar simulation (LIVAS) shows that ALH average biases over scenes with MODIS τ ≥ are in the range of 260–800 m. These results depend on the assumed aerosol single scattering albedo (sensitivity up to 600 m) and the chosen surface albedo (variation less than 200 m). Scenes with τ ≤ 0.5 are expected to show too large biases due to the little impacts of particles on the O2–O2 SCD changes. In addition, NN algorithms also enable aerosol optical thickness retrieval by exploring the OMI reflectance in the continuum. Comparisons with collocated MODIS-Aqua show agreements between −0.02 ± 0.45 and −0.18 ± 0.24 depending on the season. Improvements may be obtained from a better knowledge of the surface albedo, and higher accuracy of the aerosol model. This study shows the first encouraging aerosol layer height retrieval results over land from satellite observations of the 477 nm O2–O2 spectral band.
Ocean–atmosphere interactions modulate irrigation's climate impacts

Published: November 2016

Abstract. Numerous studies have focused on the local and regional climate effects of irrigated agriculture and other land cover and land use change (LCLUC) phenomena, but there are few studies on the role of ocean–atmosphere interaction in modulating irrigation climate impacts. Here, we compare simulations with and without interactive sea surface temperatures of the equilibrium effect on climate of contemporary (year 2000) irrigation geographic extent and intensity. We find that ocean–atmosphere interaction does impact the magnitude of global-mean and spatially varying climate impacts, greatly increasing their global reach. Local climate effects in the irrigated regions remain broadly similar, while non-local effects, particularly over the oceans, tend to be larger. The interaction amplifies irrigation-driven standing wave patterns in the tropics and midlatitudes in our simulations, approximately doubling the global-mean amplitude of surface temperature changes due to irrigation. The fractions of global area experiencing significant annual-mean surface air temperature and precipitation change also approximately double with ocean–atmosphere interaction. Subject to confirmation with other models, these findings imply that LCLUC is an important contributor to climate change even in remote areas such as the Southern Ocean, and that attribution studies should include interactive oceans and need to consider LCLUC, including irrigation, as a truly global forcing that affects climate and the water cycle over ocean as well as land areas.
Brief communication: Extended chronology of the Cordón Caulle volcanic eruption beyond 2011 reveals toxic impacts
Authors: Flueck Werner T.
Published: November 2016

Abstract. Aside of immediate impacts, the 2011 Puyehue–Cordón Caulle volcano (PCC) eruption also caused persisting chemical impacts. By 2012, toxicity resulted in overt dental fluorosis in deer, with bone fluoride increasing > 38-fold to 5175 ppm. Sheep, horses and cattle also succumbed to fluorosis. Due to eolian redeposition of tephra, exposure of ruminants continued, bone fluoride reached 10 396 ppm, and by 2014 skeletal fluorosis was found. Nonskeletal fluorosis resulted in reduced wool growth and major losses among periparturient cattle. Peculiarities of digestive processes make ruminants susceptible to fluoride-containing tephra, which averaged 548 ppm from PCC. Moreover, recent volcanic eruptions causing fluorosis could be aggravated by local iodine deficiency, which increases the incidence and harshness of fluorosis, and deficiency of selenium, which, among other things, also results in secondary deficiency of iodine. Notwithstanding, several measures are available to livestock producers to minimize chemical impacts of fluoride.

Published: November 2016

The ability of stress to induce immune suppression is widely recognized, but the mechanisms underlying the effects of stress on the adaptive immune system during tumor progression are not completely understood. To study the effect of stress on the immune system in vivo, we used a preclinical immunocompetent mouse model bearing 4T1 mammary adenocarcinoma cells. Mice were randomized into 4 groups, including social isolation (SI), acute restraint stress (aRRS), chronic restraint stress (cRRS), or no stress (NS). We found that SI significantly decreased the number of tumor-bearing mice still alive at the end of protocol (28 days), compared to NS mice. Although we did not detect significant changes in primary tumor volume, we observed a significant increase in the endothelial marker CD31 in primary tumors of SI mice and in lung metastases in SI and RRS mice. Survival decline in SI mice was associated with significant decreases in splenic CD8 cells and in activated T cells. From a mechanistic standpoint, RRS increased expression of FOXP3, CXCL-10, and granzyme B in mouse tumors, and the effects were reversed by propranolol. Our data demonstrate that various forms of stress differentially impact adaptive immunity and tumor angiogenesis, and negatively impact survival.

Statistical Analyses of Court Decisions: An Example of Multilevel Models of Sentencing

Quantitative empirical research into legal decisions must be conducted using statistical tools that are appropriate for the data involved. Court decisions are one example of a domain where the data is intrinsically hierarchical (i.e., multilevel), since decisions are made on individual cases by decision-makers in courts located across geographical (or jurisdictional) areas. Past research into court decisions has often either neglected higher level variables or incorrectly used single-level statistical models to analyze multilevel data. The lack of a clear understanding about when and why multilevel statistical models are required may have contributed to this situation. In this paper, we identify the problems of estimating single-level models on hierarchically structured data, and consider the advantages of conducting multilevel analyses under these circumstances. We use the example of criminal sentencing research to illustrate the arguments for the use of multilevel models and against a single-level approach. We also highlight some issues to be addressed in future sentencing studies.

Hydrogen Peroxide Wound Irrigation in Orthopaedic Surgery
Authors: Lu Min , Hansen Erik Nathan
Published: November 2016

Abstract. As the burden of deep hardware infections continues to rise in orthopaedics, there is increasing interest in strategies for more effective debridement of colonized tissues and biofilm. Hydrogen peroxide has been used medically for almost a century, but its applications in orthopaedic surgery have yet to be fully determined. The basic science and clinical research on the antiseptic efficacy of hydrogen peroxide have demonstrated its efficacy against bacteria, and it has demonstrated potential synergy with other irrigation solutions such as chlorhexidine and povidone-iodine. While hydrogen peroxide is effective in infection reduction, there are concerns with wound healing, cytotoxicity, and embolic phenomena, and we recommend against hydrogen peroxide usage in the treatment of partial knee replacements, hemiarthroplasties, or native joints. Additionally, due to the potential for oxygen gas formation, hydrogen peroxide should not be used in cases of dural compromise, when pressurizing medullary canals, or when irrigating smaller closed spaces to avoid the possibility of air embolism. Finally, we present our protocol for irrigation and debridement and exchange of modular components in total joint arthroplasty, incorporating hydrogen peroxide in combination with povidone-iodine and chlorhexidine.
