Recognition and Grasping of Disorderly Stacked Wood Planks Using a Local Image Patch and Point Pair Feature Method
Authors: Xu Chengyi , Liu Ying , Ding Fenglong , Zhuang Zilong
Published: November 2020

Considering the difficult problem of robot recognition and grasping in the scenario of disorderly stacked wooden planks, a recognition and positioning method based on local image features and point pair geometric features is proposed here and we define a local patch point pair feature. First, we used self-developed scanning equipment to collect images of wood boards and a robot to drive a RGB-D camera to collect images of disorderly stacked wooden planks. The image patches cut from these images were input to a convolutional autoencoder to train and obtain a local texture feature descriptor that is robust to changes in perspective. Then, the small image patches around the point pairs of the plank model are extracted, and input into the trained encoder to obtain the feature vector of the image patch, combining the point pair geometric feature information to form a feature description code expressing the characteristics of the plank. After that, the robot drives the RGB-D camera to collect the local image patches of the point pairs in the area to be grasped in the scene of the stacked wooden planks, also obtaining the feature description code of the wooden planks to be grasped. Finally, through the process of point pair feature matching, pose voting and clustering, the pose of the plank to be grasped is determined. The robot grasping experiment here shows that both the recognition rate and grasping success rate of planks are high, reaching 95.3% and 93.8%, respectively. Compared with the traditional point pair feature method (PPF) and other methods, the method present here has obvious advantages and can be applied to stacked wood plank grasping environments.
Deep Learning-Based Positioning of Visually Impaired People in Indoor Environments

Published: November 2020

Wayfinding and navigation can present substantial challenges to visually impaired (VI) people. Some of the significant aspects of these challenges arise from the difficulty of knowing the location of a moving person with enough accuracy. Positioning and localization in indoor environments require unique solutions. Furthermore, positioning is one of the critical aspects of any navigation system that can assist a VI person with their independent movement. The other essential features of a typical indoor navigation system include pathfinding, obstacle avoidance, and capabilities for user interaction. This work focuses on the positioning of a VI person with enough precision for their use in indoor navigation. We aim to achieve this by utilizing only the capabilities of a typical smartphone. More specifically, our proposed approach is based on the use of the accelerometer, gyroscope, and magnetometer of a smartphone. We consider the indoor environment to be divided into microcells, with the vertex of each microcell being assigned two-dimensional local coordinates. A regression-based analysis is used to train a multilayer perceptron neural network to map the inertial sensor measurements to the coordinates of the vertex of the microcell corresponding to the position of the smartphone. In order to test our proposed solution, we used IPIN2016, a publicly-available multivariate dataset that divides the indoor environment into cells tagged with the inertial sensor data of a smartphone, in order to generate the training and validating sets. Our experiments show that our proposed approach can achieve a remarkable prediction accuracy of more than 94%, with a 0.65 m positioning error.
Addictions in Spanish College Students in Confinement Times: Preventive and Social Perspective
Authors: Lázaro-Pérez Cristina , Martínez-López José Ángel , Gómez-Galán José
Published: November 2020

Diverse studies have shown that a significant percentage of the Spanish university population suffers from different addictions. They are both a personal and public health problem if there is not a greater awareness of the risks involved and if the appropriate prevention measures are not taken, among them educational ones. In this context, a descriptive and explanatory cross-sectional study was conducted during the first half of June 2020, coinciding with the period of confinement that occurred in Spain during the first wave of the COVID-19 pandemic. Given that this is such an exceptional time, the main objective of this study was to obtain information especially on students’ substance consumption and possible addictions at this time. Knowing the specific situation of this problem in that specific situation may allow for comparative studies in the future. The sample was composed of 310 university students from 14 Spanish universities. The instrument used in the research was the ASSIST questionnaire, developed by the WHO for the detection of alcohol, tobacco, and substance consumption. As result, a moderate and high risk was observed mainly in the following substances: alcohol (36.2%), tobacco (33.2%), cannabis (22.9%), and sedatives (10.3%). Through the logistic regression of the set of drugs, it has been proven that, on the one hand, the addiction to cocaine and sedatives in the family environment and age, on the other hand, are the main predictive variables of drug consumption. The existence of polysubstance abuse was also determined. These data show the need for educational bodies and university institutions to promote awareness, sensitization, and health education programs to deal with this important problem, especially in extraordinary situations, such as the one referred to, which could increase this consumption.
Trade and Strike Activity in the Postwar United States
Authors: Abouharb M. Rodwan , Fordham Benjamin O.
Published: November 2020

This paper examines the effect of international trade on strike activity within the United States since World War II. Globalization may influence strike activity through its effects on the bargaining position of labor. Alternatively, if labor and management take their changed bargaining positions into account, the rate of change in openness could create greater uncertainty in negotiations between them and lead to more strikes as a result. Empirical analysis of strike activity in the 50 states over this period supports the argument concerning uncertainty in the bargaining process. Import competition may also indirectly reduce strike activity by decreasing union density.
Attractiveness of Bike-Sharing Stations from a Multi-Modal Perspective: The Role of Objective and Subjective Features
Authors: Nogal Maria , Jiménez Pilar
Published: November 2020

When analysing the performance of bike-sharing scheme (BSS) stations, it is common to find stations that are located in specific points that capture the interest of users, whereas nearby stations are clearly underused. This uneven behaviour is not totally understood. This paper discusses the potential factors influencing station attractiveness, supported by the related literature on cyclists’ and pedestrians’ preferences and the characteristics of the stations themselves. The existing literature addresses these topics independently, while this work unites them by proposing a non data-extensive methodology that allows the attractiveness of BSS stations to be assessed. Attractiveness in this context is understood as the set of physical, environmental and service-related features of a bike station that make it more appealing for BSS users than nearby stations. Special attention is paid to differentiating objective features, based on facts, from subjective features, those influenced by personal perceptions. This classification becomes important in this context because subjective aspects can change from one geographical location to another, making the findings related to these aspects difficult to apply to other regions. Moreover, the assessment of the stations’ levels of safety and security is included. Thus, the proposed measure of attractiveness of BSS stations provides a balanced overview of several features. The consideration of station attractiveness when designing BSS layouts will help to refine the design of new layouts and will assist in conducting an appropriate diagnostic evaluation of the existing ones. This tool will allow urban and transportation planners to reduce re-balancing costs and to maximise user satisfaction at a low cost, which have a direct impact on improving the urban sustainability. The proposed method is applied to the Dublin bike sharing scheme, Dublinbikes, with good performance results.
Ceramic Workshop Adapted with 3D Technologies to Improve the Self-Esteem of People with Disabilities
Authors: Bonnet de León Alejandro , Meier Cecile , Saorin Jose Luis
Published: November 2020

This paper describes a process to adapt tools in an artistic ceramic workshop in which custom molds are created using low-cost digital manufacturing technologies. The digitalization of busts by a 3D scanner and their transformation into 3D printed molds is a simple technique that only requires basic digital tools. These molds were used in the artistic ceramic workshop of the Psychopedagogical Center of the Order of San Juan de Dios in Tenerife, where the authors worked with people with intellectual disabilities to make ceramic pieces. These people, in most cases, do not have the necessary skills for detail modeling; however, with the help of digital manufacturing technologies, they can produce molds of their own faces and create personalized figures autonomously. In this way, they increase their self-esteem and autonomy and discover new possibilities for making products; as a result, they feel fulfilled and confirm that they can be part of the creation process. To obtain an evaluation of the activity, a qualitative study was carried out, and observation data were collected. The attitudes of the users were compared with observations made during a similar activity without using molds or technologies. It was observed that the attitude of the participants significantly improved when they obtained more satisfactory results with the use of molds.
Gender-Responsive Public Transportation in the Dammam Metropolitan Region, Saudi Arabia

Published: November 2020

The limited availability of public transportation in Saudi Arabia leads to an increased demand for private vehicles. An increase in using private cars does not meet the global sustainability goals, e.g., reducing energy consumption and improving the air quality. Road users should be encouraged to use sustainable mobility modes, particularly public transportation, equally accessible to both men and women However, women’s mobility has been somewhat limited and challenged in spatio-temporal terms, and partly due to socio-cultural barriers. This study attempts to understand the gender experience of a sample of public transport users and consider their aspirations and needs into daily mobility. A survey campaign (structured interviews and online questionnaires) was launched in the Dammam Metropolitan Region (DMR), taking four different types of respondents into account. The results suggest a predominant preference for taxis for shopping and leisure activities due to a poor public transport service, pivotally characterized by limited operational routes, hours, and infrastructure. This study ponders upon the adequacy of the supporting infrastructures and interior design of the public buses to women’s needs and compare them with global best practices. The results suggest that, due to the absence of a gender-responsive design and infrastructure, women are forced to use taxis, although privacy and a sense of insecurity often become concerns when traveling alone or with children. The study results allow future research to be expanded, considering women’s mobility patterns, needs, and embedded barriers by comparing the results with current transport policies, plans, and practices.
Breaking the Black-Box of Regional Resilience: A Taxonomy Using a Dynamic Cumulative Shift-Share Occupational Approach
Authors: Rota Francesca Silvia , Bagliani Marco , Feletig Paolo
Published: November 2020

In the European literature on the regional and local development, the concept of resilience has progressively gained momentum, eventually overcoming that of competitiveness and posing a critical challenge for the future of territorial studies and the territorialisation of the policy discourse. In the current economic turmoil, the success of an urban and regional economy relies more and more on its capacity to react to sudden shocks in a positive and evolutionary perspective, i.e., in its resilience. Nevertheless, as a recent analysis of the employment dynamics of Italian metro-regions in the period before and after 2008 has demonstrated that the existing taxonomies may be distant from reality and hardly communicable. The paper proposes a taxonomy of regional resilience based on the consideration of the region’s capacity of both improving its employment rate during the pre-crisis period and overcoming the concurrent performance of the nation. Via a shift-share analysis of the employment in Italian metro-regions, the paper investigates the contribution of the sectoral structure of the local labour market in terms of economic resilience. The result is twofold: a geography of the dynamism of the territorial systems in Italy that diverges from some “classic” interpretative frameworks; a novel taxonomic approach to regional resilience.
Recycling Tire Rubber in Asphalt Pavements: State of the Art
Authors: Alfayez Saud A. , Suleiman Ahmed R. , Nehdi Moncef L.
Published: November 2020

The use of recycled tire rubber in asphalt pavements to improve the overall performance, economy, and sustainability of pavements has gained considerable attention over the last few decades. Several studies have indicated that recycled tire rubber can reduce the permanent deformation of flexible pavements and enhance its resistance to rutting, reduce pavement construction and maintenance costs, and improve the resistance to fatigue damage. This paper provides a systematic and critical overview of the research on and practice of using recycled tire rubber in asphalt pavements in terms of engineering properties, performance, and durability assessment. This critical analysis of the state-of-the-art should enhance the understanding of using recycled tire rubber in asphalt pavements, define pertinent recommendations, identify knowledge gaps, and highlight the need for concerted future research.

Published: November 2020

The growth of environmental awareness and more robust enforcement of numerous regulations to reduce greenhouse gas (GHG) emissions have directed efforts towards addressing current environmental challenges. Considering the Vehicle Routing Problem (VRP), one of the effective strategies to control greenhouse gas emissions is to convert the fossil fuel-powered fleet into Environmentally Friendly Vehicles (EFVs). Given the multitude of constraints and assumptions defined for different types of VRPs, as well as assumptions and operational constraints specific to each type of EFV, many variants of environmentally friendly VRPs (EF-VRP) have been introduced. In this paper, studies conducted on the subject of EF-VRP are reviewed, considering all the road transport EFV types and problem variants, and classifying and discussing with a single holistic vision. The aim of this paper is twofold. First, it determines a classification of EF-VRP studies based on different types of EFVs, i.e., Alternative-Fuel Vehicles (AFVs), Electric Vehicles (EVs) and Hybrid Vehicles (HVs). Second, it presents a comprehensive survey by considering each variant of the classification, technical constraints and solution methods arising in the literature. The results of this paper show that studies on EF-VRP are relatively novel and there is still room for large improvements in several areas. So, to determine future insights, for each classification of EF-VRP studies, the paper provides the literature gaps and future research needs.

Authors: Yen Chen-Piao , Zhou Song-Yan , Shen Yun-Hwei
Published: November 2020

The treatment and disposal of municipal solid waste incineration (MSWI) fly ash containing significant amounts of dissolvable salts and heavy metals is a seriously challenge. At present, the common treatment method for MSWI fly ash in Taiwan is the cement-based stabilization/solidification (S/S) process. In this work, an integrated hydrometallurgical process for the treatment of MSWI fly ash was evaluated. Ca was first recovered by combining water washing and ion exchange sequentially. Meanwhile, Zn in the water-washed fly ash was recovered by combining acid leaching and ion exchange sequentially. Combining the water washing efficiency of 30% on raw ash and the acid leaching efficiency of 40% on pre-washed ash, a total of 58% mass reduction rate of fly ash was achieved. In addition, an 80% Zn and 58% Ca recovery was achieved.
Perspective of Local Government on the Performance Assessment of District Sports and Leisure Centers
Authors: Fang Chin-Yi Fred
Published: November 2020

This paper addresses the problem of performance management of operate-transfer (OT) project finance for public sports and leisure centers (SLC) from the perspective of local government. This study contributes to use an evolutionary theory of competitive advantage and mixed-methods, including a modified Delphi method to develop the efficiency-based performance model (EPM) under OT project finance for the public SLCs. The total-factor framework disaggregating the efficiency into an innovative output surplus target ratio (OSTR) provides local governments with a contracted period to manage the SLCs through further specific improvement advice. This study further proposed the four-quadrant matrix formulated by long-term efficiency and short-term profitability to identify the benchmark and improvement directions. The empirical results indicated that there are fifteen SLCs located in the benchmark quadrant. This study provides policy makers in the local governments with a scientific reference to keep or drop the current operating private enterprise in the next concession period. The most underperforming SLCs could follow this proposed quadrant analysis and OSTR index, utilizing their internal resources to develop more attractive and reasonable-price exercise courses for participant growth.

Authors: Maletič Damjan , Maletič Matjaž , Al-Najjar Basim , Gomišček Boštjan
Published: November 2020

The commitment of organisations to physical assets management (PAM) has recently received considerable attention in theory and practice. Indeed, PAM plays a key role in asset-intensive organizations and is also considered as a principal actor within Industry 4.0. Therefore, this paper aims to examine the PAM core practices and the performance implications of integrating these practices into business, in particular by assessing their impact on operational performance. Survey data were collected from managers in 138 international and local organisations. The data was analysed using Partial Least Squares Path Modeling (PLS-PM). The study validates the second-order construct consisting of PAM latent variables, namely Strategy and Planning, Risk management, Lifecycle Delivery, Asset Information, and Asset Review. The results have shown that PAM core practices directly influence operational performance. This paper is a response to recent calls for empirical studies on the organisational approaches that can increase the success of organisations.
Rumor Detection on Social Media via Fused Semantic Information and a Propagation Heterogeneous Graph
Authors: Ke Zunwang , Li Zhe , Zhou Chenzhi , Sheng Jiabao , Silamu Wushour , Guo Qinglang
Published: November 2020

Social media had a revolutionary impact because it provides an ideal platform for share information; however, it also leads to the publication and spreading of rumors. Existing rumor detection methods have relied on finding cues from only user-generated content, user profiles, or the structures of wide propagation. However, the previous works have ignored the organic combination of wide dispersion structures in rumor detection and text semantics. To this end, we propose KZWANG, a framework for rumor detection that provides sufficient domain knowledge to classify rumors accurately, and semantic information and a propagation heterogeneous graph are symmetry fused together. We utilize an attention mechanism to learn a semantic representation of text and introduce a GCN to capture the global and local relationships among all the source microblogs, reposts, and users. An organic combination of text semantics and propagating heterogeneous graphs is then used to train a rumor detection classifier. Experiments on Sina Weibo, Twitter15, and Twitter16 rumor detection datasets demonstrate the proposed model’s superiority over baseline methods. We also conduct an ablation study to understand the relative contributions of the various aspects of the method we proposed.
In-Vitro Neutralization of the Neurotoxicity of Coastal Taipan Venom by Australian Polyvalent Antivenom: The Window of Opportunity
Authors: Madhushani Umesha , Isbister Geoffrey K. , Tasoulis Theo , Hodgson Wayne C. , Silva Anjana
Published: November 2020

Coastal taipan (Oxyuranus scutellatus) envenoming causes life-threatening neuromuscular paralysis in humans. We studied the time period during which antivenom remains effective in preventing and arresting in vitro neuromuscular block caused by taipan venom and taipoxin. Venom showed predominant pre-synaptic neurotoxicity at 3 µg/mL and post-synaptic neurotoxicity at 10 µg/mL. Pre-synaptic neurotoxicity was prevented by addition of Australian polyvalent antivenom before the venom and taipoxin and, reversed when antivenom was added 5 min after venom and taipoxin. Antivenom only partially reversed the neurotoxicity when added 15 min after venom and had no significant effect when added 30 min after venom. In contrast, post-synaptic activity was fully reversed when antivenom was added 30 min after venom. The effect of antivenom on pre-synaptic neuromuscular block was reproduced by washing the bath at similar time intervals for 3 µg/mL, but not for 10 µg/mL. We found an approximate 10–15 min time window in which antivenom can prevent pre-synaptic neuromuscular block. This time window is likely to be longer in envenomed patients due to the delay in venom absorption. Similar effectiveness of antivenom and washing with 3 µg/mL venom suggests that antivenom most likely acts by neutralizing pre-synaptic toxins before they interfere with neurotransmission inside the motor nerve terminals.

Ciguatera Poisoning (CP) is a human food-borne poisoning that has been known since ancient times to be found mainly in tropical and subtropical areas, which occurs when fish or very rarely invertebrates contaminated with ciguatoxins (CTXs) are consumed. The genus of marine benthic dinoflagellates Gambierdiscus produces CTX precursors. The presence of Gambierdiscus species in a region is one indicator of CP risk. The Canary Islands (North Eastern Atlantic Ocean) is an area where CP cases have been reported since 2004. In the present study, samplings for Gambierdiscus cells were conducted in this area during 2016 and 2017. Gambierdiscus cells were isolated and identified as G. australes, G. excentricus, G. caribaeus, and G. belizeanus by molecular analysis. In this study, G. belizeanus is reported for the first time in the Canary Islands. Gambierdiscus isolates were cultured, and the CTX-like toxicity of forty-one strains was evaluated with the neuroblastoma cell-based assay (neuro-2a CBA). G. excentricus exhibited the highest CTX-like toxicity (9.5–2566.7 fg CTX1B equiv. cell−1) followed by G. australes (1.7–452.6.2 fg CTX1B equiv. cell−1). By contrast, the toxicity of G. belizeanus was low (5.6 fg CTX1B equiv. cell−1), and G. caribaeus did not exhibit CTX-like toxicity. In addition, for the G. belizeanus strain, the production of CTXs was evaluated with a colorimetric immunoassay and an electrochemical immunosensor resulting in G. belizeanus producing two types of CTX congeners (CTX1B and CTX3C series congeners) and can contribute to CP in the Canary Islands.
Conformal Anomaly in Yang-Mills Theory and Thermodynamics of Open Confining Strings
Authors: Chernodub Maxim N.
Published: November 2020

We discuss thermodynamic properties of open confining strings introduced via static sources in the vacuum of Yang-Mills theory. We derive new sum rules for the chromoelectric and chromomagnetic condensates and use them to show that the presence of the confining string lowers the gluonic pressure in the bulk of the system. The pressure deficit of the gluon plasma is related to the potential energy in the system of heavy quarks and anti-quarks in the plasma.
Self-Adjoint Extension Approach to Motion of Spin-1/2 Particle in the Presence of External Magnetic Fields in the Spinning Cosmic String Spacetime
Authors: M. Cunha Márcio , O. Silva Edilberto
Published: November 2020

In this work, we study the relativistic quantum motion of an electron in the presence of external magnetic fields in the spinning cosmic string spacetime. The approach takes into account the terms that explicitly depend on the particle spin in the Dirac equation. The inclusion of the spin element in the solution of the problem reveals that the energy spectrum is modified. We determine the energies and wave functions using the self-adjoint extension method. The technique used is based on boundary conditions allowed by the system. We investigate the profiles of the energies found. We also investigate some particular cases for the energies and compare them with the results in the literature.
Message Sent, Now What? A Critical Analysis of the Heat Action Plan in Ahmedabad, India
Authors: Nastar Maryam
Published: November 2020

To protect public health, heat-related policies are increasingly being adopted by city authorities to address the unequal impact of heatwaves. Ahmedabad’s Heat Action Plan (HAP) is an acclaimed and successful policy response in India and beyond. While the pilot evaluation of the initiative suggests that almost a thousand deaths were avoided annually after its implementation, it is not yet clear whose lives were saved, and to what extent this statistic was due to the HAP, rather than other factors. By reviewing the published and grey literature centering on the HAP target groups, outreach strategies, and impacts on urban services, this paper points out major knowledge gaps concerning the potentials and impacts of the HAP, which may lead to the systematical exclusion of vulnerable and disadvantaged groups from the intended benefits. In this paper, it is argued that the effectiveness and inclusiveness of the HAP predominantly depend on its integration into urban development projects, which is a challenging task given the existing horizontal and vertical fragmentation in the planning of city projects. Moreover, urban plans and policies, including the HAP, are shown to be overly focused on technology, and as a consequence, they do not realize their limited scope in addressing the associated issues, which are fundamentally social, deep, and structural, such as spatial inequality in Indian cities.
Porcine Reproductive and Respiratory Syndrome Virus Reverse Genetics and the Major Applications
Authors: Chaudhari Jayeshbhai , Vu Hiep L. X.
Published: November 2020

Porcine reproductive and respiratory syndrome virus (PRRSV) is a positive sense, single-stranded RNA virus that is known to infect only pigs. The virus emerged in the late 1980s and became endemic in most swine producing countries, causing substantial economic losses to the swine industry. The first reverse genetics system for PRRSV was reported in 1998. Since then, several infectious cDNA clones for PRRSV have been constructed. The availability of these infectious cDNA clones has facilitated the genetic modifications of the viral genome at precise locations. Common approaches to manipulate the viral genome include site-directed mutagenesis, deletion of viral genes or gene fragments, insertion of foreign genes, and swapping genes between PRRSV strains or between PRRSV and other members of the Arteriviridae family. In this review, we describe the approaches to construct an infectious cDNA for PRRSV and the ten major applications of these infectious clones to study virus biology and virus–host interaction, and to design a new generation of vaccines with improved levels of safety and efficacy.
A Novel Approach for the Treatment of T Cell Malignancies: Targeting T Cell Receptor Vβ Families
Authors: Wang Jie , Urbanska Katarzyna , Sharma Prannda , Nejati Reza , Shaw Lauren , Lim Megan S. , Schuster Stephen J. , Jr. Daniel J. Powell
Published: November 2020

Peripheral T cell lymphomas (PTCLs) are generally chemotherapy resistant and have a poor prognosis. The lack of targeted immunotherapeutic approaches for T cell malignancies results in part from potential risks associated with targeting broadly expressed T cell markers, namely T cell depletion and clinically significant immune compromise. The knowledge that the T cell receptor (TCR) β chain in human α/β TCRs are grouped into Vβ families that can each be targeted by a monoclonal antibody can therefore be exploited for therapeutic purposes. Here, we develop a flexible approach for targeting TCR Vβ families by engineering T cells to express a chimeric CD64 protein that acts as a high affinity immune receptor (IR). We found that CD64 IR-modified T cells can be redirected with precision to T cell targets expressing selected Vβ families by combining CD64 IR-modified T cells with a monoclonal antibody directed toward a specific TCR Vβ family in vitro and in vivo. These findings provide proof of concept that TCR Vβ-family-specific T cell lysis can be achieved using this novel combination cell–antibody platform and illuminates a path toward high precision targeting of T cell malignancies without substantial immune compromise.
Promotion of Cellular and Humoral Immunity against Foot-and-Mouth Disease Virus by Immunization with Virus-Like Particles Encapsulated in Monophosphoryl Lipid A and Liposomes

Published: November 2020

Virus-like particles (VLPs) have emerged as promising vaccine candidates against foot-and-mouth disease (FMD). However, such vaccines provide a relatively low level of protection against FMD virus (FMDV) because of their poor immunogenicity. Therefore, it is necessary to design effective vaccine strategies that induce more potent immunogenicity. In order to investigate the means to improve FMD VLP vaccine (VLPFMDV) immunogenicity, we encapsulated VLPs (MPL/DDA-VLPFMDV) with cationic liposomes based on dimethyldioctadecylammonium bromide (DDA) and/or monophosphoryl lipid A (MPL, TLR4 agonist) as adjuvants. Unlike inactivated whole-cell vaccines, VLPFMDV were successfully encapsulated in this MPL/DDA system. We found that MPL/DDA-VLPFMDV could induce strong cell-mediated immune responses by inducing not only VLP-specific IFN-γ+CD4+ (Th1), IL-17A+CD4+ (Th17), and IFN-γ+CD8+ (activated CD8 response) T cells, but also the development of VLP-specific multifunctional CD4+ and CD8+ memory T cells co-expressing IFN-γ, TNF-α, and IL-2. In addition, the MPL/DDA-VLPFMDV vaccine markedly induced VLP-specific antibody titers; in particular, the vaccine induced greater Th1-predominant IgG responses than VLPFMDV only and DDA-VLPFMDV. These results are expected to provide important clues for the development of an effective VLPFMDV that can induce cellular and humoral immune responses, and address the limitations seen in current VLP vaccines for various diseases.
An Indigenous Research Methodology That Employs Anishinaabek Elders, Language Speakers and Women’s Knowledge for Sustainable Water Governance
Authors: Chiblow Susan
Published: November 2020

Indigenous research paradigms are congruent to Indigenous worldviews and have become more dominant in areas such as Indigenous policy and education. As Indigenous research paradigms continue to gain momentum, the historical legacy of unethical research is addressed as more Indigenous communities and organizations develop their own research protocols. There is a plethora of articles explaining Indigenous research methodologies, but few examine the inclusion of the knowledge from Elders, language speakers, and Indigenous women in sustainable water governance. My Indigenous research methodology draws on the works of Indigenous scholars Shawn Wilson, Linda Smith, and Margaret Kovach, with specific focus on Wendy Geniusz’s Biskaabiiyang. My Indigenous research methodology is specific to the Anishinaabe territory of the Great Lakes region and includes Anishinaabek Elders, Anishinaabemowin (Ojibway language) speakers, and Anishinaabek women. This article seeks to contribute to Indigenous research paradigms and methods by elucidating the importance of engaging Anishinaabek Elders, Anishinaabemowin speakers, and Anishinaabek women in sustainable water governance.
DEVICES AND VENTILATION PROCESS DURING EXECUTION ELECTRIC WELDING
Authors: Shaptala V. , Hukalenko E. , Severin N. , Gusev Y.
Published: November 2020

The main direction of normalizing the parameters of the air during electric welding is proposed to consider the installation of an integrated ventilation system that combines local exhaust ventilation of welder jobs and general ventilation of rooms. In the article using the computer simulation method, the fields of air mobility, its temperature and concentration of harmful impurities are calculated and a comparative analysis of the main types of stationary devices for local exhaust ventilation of electric welding jobs: exhaust umbrellas, welding panels, and suction blowers, as well as the conditions for effective use of rotary suction pumps. Factors affecting the efficiency of their work are identified and combinations of influencing factors that provide the maximum permissible concentration of harmful emissions in the welders' working areas are established. The conditions are determined under which the general exchange effect of local suction is sufficient to maintain indoor concentration at the MPC level. The results obtained can be used to develop engineering methods for calculating and optimizing ventilation devices and systems, as well as to analyze structural and design solutions for ventilation devices in electric welding plants.
The Dual Use of Religious-Faith in Intimate Partner Abuse Perpetration: Perspectives of Latino Men in a Parish-based Intervention Program
Authors: Davis Maxine , Jonson-Reid Melissa
Published: November 2020

Little is known about the role that religious-faith plays in the lives of men who have acted abusively against an intimate partner. Studies report mixed findings about the relationship between religious-faith and intimate partner violence/abuse (IPV/A) perpetration. This study explored the perceptions of Latino men involved in a parish-based partner abuse intervention program (PAIP). Two focus groups were conducted with members of the PAIP (N=18). Two major themes emerged. Participants reported using religious-faith as a mechanism for ending violence. However, participants also reported past misuse of religion in order to gain control over intimate partners. These apparently conflicting roles of religion were further elucidated in several sub-themes. Religious-faith is complex. This study offers insight into how faith may serve as both a risk and protective factor for IPV/A perpetration. Implications for how intervention programs may address participants’ religious-faith during treatment and how religio-spiritual abuse is measured are discussed.
Utilizing Brief Spiritual Assessments with Clients who belong to the Church of Jesus Christ of Latter-day Saints:
Authors: Limb Gordon , Hodge David , Alboroto Richard
Published: November 2020

In recent years social work has increasingly focused on spirituality and religion as key elements of cultural competency.  The Joint Commission—the nation's largest health care accrediting organization—as well as many other accrediting bodies require spiritual assessments in hospitals and many other mental health settings. Consequently, specific intervention strategies have been fostered in order to provide the most appropriate interventions for religious clients. The Church of Jesus Christ of Latter-day Saints is the fourth largest and one of the faster growing churches in the United States.  In an effort to facilitate cultural competence with clients who are members of the Church of Jesus Christ, a brief spiritual assessment instrument was developed.  This mixed-method study asked experts in Church culture (N = 100) to identify the degree of cultural consistency, strengths, and limitations of the brief spiritual assessment instrument. Results indicate that the framework is consistent with Church culture and a number of practice-oriented implications are offered.

Work accidents are unwanted and unexpected events. Based on the Loss Caution Model theory, the direct causes of accidents are unsafe action and unsafe conditions. The purpose of this study was to analyze the relationship between personal factors and work supervision and unsafe action in welding workers at the Abun Las Workshop. This research type is quantitative with cross sectional research design. The population in this study were all welding workers, amounting to 34 people. The sampling technique was using the total sampling technique. The research instruments used in this study were questionnaires and observation sheets. The data obtained were processed by using the chi square statistical test with the degree of significance (α) = 0.05. The results of the analysis of the relationship between personal factors and work supervision with unsafe action on welding workers at the Las Abun Workshop are described as follows: personal factors (p value = 0.002) <α (0.05), this means that there is a significant relationship between personal factors (knowledge) and unsafe action on welding workers at the Las Abun Workshop, work supervision (p value = 0.038) <α (0.05), this means that there is a significant relationship between work supervision and unsafe action on welding workers at the Las Abun Workshop. Suggestions for the Abun Welding Workshop industry It is better if the Welding Workshop Industry has Occupational Safety and Health (K3) experts who can control and supervise all activities of welding workers at any time.
FIELD EVALUATION OF MINE BLASTING EFFICIENCY

The efficiency of drilling and blasting operations can be assessed in different ways, depending on the desired effect. The evaluation can be performed on the basis of the quality of the explosives applied for rock extraction. On the other hand, the correct assessment should include the results of drilling and blasting works. One of the parameters that are commonly used in the quality assessment of explosives is the on-site testing of the detonation velocity, which is a direct indicator of the efficiency of explosives. The quality of explosives is essential for the appropriate blasting process and should be subjected to regular verification by means of measurements under different site conditions. Since in most cases the excavated rock must be transported from the blasting site to another location, one of the main parameters that can be used for drilling and blasting operations assessment is fragmentation analysis. It may be done using various image-based particles sizing software. The article presents selected methods that can be applied for the evaluation of blasting works efficiency, including measurements of detonation velocity as well as fragmentation analysis based on photogrammetric methods.

In this work, the maps of the atmospheric air condition in the territory of the Republic of Bashkortostan were built taking into account the influence of the relief on the dispersion of pollutants. As a calculation model, a modified technique of V.A. Petrukhin and V.A. Vishensky was used. To increase the accuracy of the results, a correction factor for the influence of the relief on the process of dispersion of pollutants was calculated. According to the maps obtained, high concentrations of pollutants and high values of the integrated air pollution index are observed near two industrial centers: Ufa-Blagoveshchensk and Salavat-Sterlitamak.
BACKGROUND CONCENTRATION OF HEAVY METALS (LEAD, CADMIUM, ZINC, COPPER, NICKEL, ARSENIC, MERCURY) IN SURFACE SOILS OF UDMURTIA CONTROLLED AT ENGINEERING-ECOLOGICAL RESEARCHES
Authors: Sturman V.I. , Loginovskaya A.N.
Published: November 2020

Materials of engineering-ecological researches on various economic objects in Udmurtia are processed and systematized. Average (background) concentration of the heavy metals which are subject to obligatory control at engineering-ecological researches (lead, cadmium, zinc, copper, nickel, arsenic, mercury) for the main associations of soils and most wide-distributed kinds of soils are defined. It is revealed that with decreasing the soil’s podzol content and increasing the soil’s clay content, concentrations of heavy metals naturally raise. In general, similar soils are characterized by similar concentrations of heavy metals and similar ratios of concentration. It is established that excesses of hygienic standards on such elements as nickel, arsenic and to a lesser extent zinc, copper and cadmium, are not only something exclusive in Udmurtia, but also spreading more and more widely, especially in soils of light structure. The received average concentration can be accepted as background one at the subsequent engineering-ecological researches in the region.

Published: November 2020

The article deals with the issue of the formation conditions and possibility of predicting storm rainfall in the territory of Perm region using atmospheric instability indices. In the course of the study, the spatial and temporal distribution of storm rainfall cases was assessed, as well as the most favorable values of meteorological parameters and synoptic situations contributing to rainfall were determined. The instability indices were calculated based on the ERA-Interim reanalysis of the spectral model of the European Center for Medium-Range Weather Forecasts (ECMWF) and the reanalysis of the American hydrodynamic model Climate Forecast System (CFS). On the basis of correlation analysis, the dependence of instability indices on the amount and average intensity of storm rainfall was estimated. The critical values of the considered instability indices were determined and corrected in relation to the studied territory. The study showed that the most frequent storm rainfall is observed in June and July in the afternoon and evening. It was found that storm rainfall is mainly associated with the passage of cold fronts. The assessment of the quality of instability indices has shown the feasibility of their use for the forecast and diagnosis of storm precipitation, including in the gradation of this dangerous phenomenon.
Roles de la resolución de problemas en el currículo oficial
Authors: Daniela Olivares  , Isidoro Segovia  , José Luis Lupiáñez
Published: November 2020

En este trabajo describimos el papel de la resolución de problemas en distintos documentos que componen el currículo oficial de educación primaria en Chile. Nuestro marco teórico toma en cuenta tres dimensiones de la resolución de problemas: los roles que puede tomar según Schoenfeld (1992) y Schroeder y Lester (1989), las características que facilitan su incorporación al currículo y los tipos de problemas sugeridos en los documentos curriculares. Elaboramos un sistema de categorías y llevamos a cabo un análisis de contenido. Concluimos que los documentos reflejan visiones diferentes y hasta contradictorias sobre el papel que juega la resolución de problemas para la enseñanza de las matemáticas, dificultando su total implementación según lo dispuesto en la normativa oficial.
