Published: January 2021

Enterovirus A71 (EV-A71) infection has emerged as a significant public health concern at the global level. Epidemic events of EV-A71 have been reported worldwide, and this succession of outbreaks has heightened concern that EV-A71 may become a public health threat. In recent years, widespread A71 enterovirus also occurred in European countries. EV-A71 infection causes hand-foot-mouth disease (HFMD), herpangina, and fever. However, it can sometimes induce a variety of neurological complications, including encephalitis, aseptic meningitis, pulmonary edema, and acute flaccid paralysis. We identified new benzimidazole derivatives and described theirin vitrocytotoxicity and broad-spectrum anti-enterovirus activity. Among them, derivative 2b resulted in interesting activity against EV-A71, and therefore it was selected for further investigations. Compound 2b proved to be able to protect cell monolayers from EV-A71-induced cytopathogenicity, with an EC50 of 3 µM. Moreover, Vero-76 cells resulted in being significantly protected from necrosis and apoptosis when treated with 2b at 20 and 80 µM. Compound 2b reduced viral adsorption to Vero-76 cells, and when evaluated in a time-of-addition assay, the derivative had the highest effect when added during the infection period. Moreover, derivative 2b reduced viral penetration into host cells. Besides, 2b did not affect intestinal monolayers permeability, showing no toxic effects. A detailed insight into the efficacy of compound 2b against EV-A71 showed a dose-dependent reduction in the viral titer, also at low concentrations. Mechanism of action investigations suggested that our derivative can inhibit viral endocytosis by reducing viral attachment to and penetration into host cells. Pharmacokinetic and toxicity predictions validated compound 2b as a good candidate for furtherin vivoassays.

Published: January 2021

Peste des petits ruminants (PPR) is a transboundary viral disease that threatens more than 1.74 billion goats and sheep in approximately 70 countries globally. In 2015, the international community set the goal of eradicating PPR by 2030, and, since then, Food and Agriculture Organization of the United Nations (FAO) and World Organization for Animal Health (OIE) have jointly developed and implemented the Global Control and Eradication Strategy for PPR. Here, data from the United Nations Food and Agriculture Organization Statistical Database (FAOSTAT), the OIE World Animal Health Information System (WAHIS), Regional Roadmap Meetings, and countries’ responses to PPR Monitoring and Assessment Tool (PMAT) questionnaires were analyzed to inform on current progress towards PPR eradication. OIE recorded the use of over 333 million doses of vaccine in 12 countries from 2015 to 2018, 41.8% of which were used in Asia and 58.2% in Africa. Between 2015 and 2019, a total of 12,757 PPR outbreaks were reported to OIE: 75.1% in Asia, 24.8% in Africa, and 0.1% in Europe. The number of global outbreaks in 2019 fell to 1218, compared with 3688 in 2015. Analysis of vaccine use and PPR outbreaks in countries indicates that disease control strategies, particularly vaccination campaigns and vaccine distribution strategies, still require scientific evaluation. It is imperative that vaccination is undertaken based on the epidemiology of the disease in a region and is coordinated between neighboring countries to restrict transboundary movements. Strengthening surveillance and post-vaccination sero-monitoring at the national level is also essential. The PPR vaccine stock/bank established by FAO, OIE, and other partners have improved the quality assurance and supply of vaccines. However, to achieve PPR eradication, filling the funding gap for vaccination campaigns and other program activities will be critical.

Authors: Park Rachel M. , Gruen Margaret E. , Royal Kenneth
Published: January 2021

(1) Background: An important aspect of dog ownership is providing veterinary care. However, features of dog ownership differ across demographic groups and these may influence veterinary client decision making and behavior. The purpose of the present study was to elucidate relationships between American dog owner characteristics and willingness to seek veterinary care. (2) Methods: A total of 858 dog owners completed an online questionnaire asking participants to rate their level of likelihood to seek veterinary care for different medical conditions, answer supplemental questions about their previous veterinary barriers, and indicate barriers that prevent them from seeking veterinary care. (3) Results: Dog owners did not differ by demographics in their willingness to seek veterinary care. However, dog owner demographic groups varied in their relationship with their dog(s), previous behaviors accessing veterinary care, and barriers that make seeking veterinary care challenging. (4) Conclusions: Education, outreach and community-based veterinary medicine efforts should allocate resources to underserved communities identified within the context that they are affected by barriers to obtaining veterinary care for their dog(s).
Prediction and Evaluation of Waterjet Pump Performance under Nonuniform Inflow Using Parallel Compressor Theory
Authors: Cao Puyu , Zhu Rui
Published: January 2021

Parallel compressor theory (PCT) is commonly used to estimate effects of inlet distortion on compressor performance. As well as compressor, the actual inflow to pump is also nonuniform and unfavorable for performances. Nowadays, insufficient understanding of nonuniform inflow effects on pump performance restricts its development. Therefore, this paper applies PCT to predict external characteristics and evaluate internal flow instability of waterjet pump under nonuniform inflow. According to features of nonuniform inflow, the traditional PCT is modified and makes waterjet pump sub-divided into two circumferential tubes owning same performances but with different inlet velocity (representing nonuniform inflow). Above all, numerical simulation has been conducted to validated the applicability and accuracy of PCT in head prediction of waterjet pump under nonuniform inflow, since area-weighted sum of each tube head (i.e., theoretical pump head) is highly consistent with simulated result. Moreover, based on identifications of when and which tube occurs stall, PCT evaluates four stall behaviors of waterjet pump: partial deep stall, partial stall, pre-stall and full stall. Furthermore, different stall behavior generates different interactions between head variation of each tube, resulting in a multi-segment head curve under nonuniform inflow. The modified PCT with associated physical interpretations are expected to provide a sufficient understanding of nonuniform inflow effects on pump performances.
Modeling Surface Processes on Debris-Covered Glaciers: A Review with Reference to the High Mountain Asia
Authors: Huo Da , Chi Zhaohui , Ma Andong
Published: January 2021

Surface processes on debris-covered glaciers are governed by a variety of controlling factors including climate, debris load, water bodies, and topography. Currently, we have not achieved a general consensus on the role of supraglacial processes in regulating climate–glacier sensitivity in High Mountain Asia, which is mainly due to a lack of an integrated understanding of glacier surface dynamics as a function of debris properties, mass movement, and ponding. Therefore, further investigations on supraglacial processes is needed in order to provide more accurate assessments of the hydrological cycle, water resources, and natural hazards in the region. Given the scarcity of long-term in situ data and the difficulty of conducting fieldwork on these glaciers, many numerical models have been developed by recent studies. This review summarizes our current knowledge of surface processes on debris-covered glaciers with an emphasis on the related modeling efforts. We present an integrated view on how numerical modeling provide insights into glacier surface ablation, supraglacial debris transport, morphological variation, pond dynamics, and ice-cliff evolution. We also highlight the remote sensing approaches that facilitate modeling, and discuss the limitations of existing models regarding their capabilities to address coupled processes on debris-covered glaciers and suggest research directions.
Socioecological System Transformation: Lessons from COVID-19
Authors: Kish Kaitlin , Zywert Katharine , Hensher Martin , Davy Barbara Jane , Quilley Stephen
Published: January 2021

Environmentalists have long warned of a coming shock to the system. COVID-19 exposed fragility in the system and has the potential to result in radical social change. With socioeconomic interruptions cascading through tightly intertwined economic, social, environmental, and political systems, many are not working to find the opportunities for change. Prefigurative politics in communities have demonstrated rapid and successful responses to the pandemic. These successes, and others throughout history, demonstrate that prefigurative politics are important for response to crisis. Given the failure of mainstream environmentalism, we use systemic transformation literature to suggest novel strategies to strengthen cooperative prefigurative politics. In this paper, we look at ways in which COVID-19 shock is leveraged in local and global economic contexts. We also explore how the pandemic has exposed paradoxes of global connectivity and interdependence. While responses shed light on potential lessons for ecological sustainability governance, COVID-19 has also demonstrated the importance of local resilience strategies. We use local manufacturing as an example of a possible localized, yet globally connected, resilience strategy and explore some preliminary data that highlight possible tradeoffs of economic contraction.

Análise do Discurso Ecossistêmica – ADE
Authors: Do Couto Hildo Honorio
Published: January 2021

O objetivo principal deste artigo é apresentar a Análise do Discurso Ecossistêmica (ADE). Ela é parte da Linguística Ecossistêmica (LE), versão da Ecolinguística que vem sendo desenvolvida no Brasil tendo como precursores os trabalhos do filósofo da linguagem Peter Finke (1996), o ecolinguista Wilhelm Trampe (1990) e a Escola de Linguística Dialética criada por Jørgen Døør e Jørgen Christian Bang. A ADE teve influência adicional de diversas fontes, como a Ecologia Profunda, as ideias de Gandhi e outras. Devido a essas origens, ao analisar um texto-discurso ela não põe a ênfase principal em ideologias políticas, como fazem as Análises do Discurso tradicionais – com raras exceções como a Análise do Discurso Positiva de Martin (2004) – mas, na defesa da vida e na luta contra o sofrimento. Ideologias políticas existem, mas a vida é considerada mais importante do que elas.

Phase-locking of octave-spanning optical frequency comb based on Kerr-lens mode-locked Yb:KYW laser to reference laser
Authors: Mitaki Masatoshi , Sugiyama Kazuhiko
Published: January 2021

We phase locked an octave-spanning optical frequency comb based on a laser-diode-pumped Kerr-lens mode-locked Yb:KYW laser to a reference laser. We controlled the cavity length of the mode-locked laser to phase lock the mode frequency of the comb to the reference laser. This was conducted using a fast piezoelectric-actuated mirror on a lead-filled mount, which was aimed at damping the mechanical resonances. We achieved a servo bandwidth of 200 kHz, a residual phase noise of 0.47 rad, and a power concentration to a carrier of 91%. To extend the locking duration of the carrier-envelope offset frequency, we compensated its slow drift using the position of the Yb:KYW crystal while the pump-laser power was controlled to achieve its phase locking. We continuously maintained the full phase locking of the comb for 3 h until the reference lasers were out of lock.

Fe2O4 nanoparticles (x = 0.0–0.25) were synthesized by the coprecipitation method. Their microstructure was investigated by X-ray diffraction with Rietveld refinement software, energy-dispersive X-ray spectroscopy, transmission electron microscopy, and Fourier transform infrared absorption spectroscopy. Their thermal, magnetic properties were investigated by thermogravimetric analysis and vibrating-sample magnetometer. The nanoparticles exhibited superparamagnetic properties, with a maximum saturation magnetization of 80.2 emu g−1 in H = 11 000 Oe at room temperature for sample with x = 0.20. The Zn nonmagnetic element content is related to the cation distribution in the superlattices and magnetic moment of the particles. The Zn0.15Fe0.85Fe2O4 nanoparticles were coated with polyvinyl pyrrolidone (PVP) with different PVP mass. Their core–shell structure was investigated, the results showed that their chemical stability and saturation magnetization were greater than those of pure Fe3O4. PVP has biological compatibility; thus, Fe0.85Zn0.15Fe2O4/PVP0.75 nanocomposite has the potential to be widely used in medical biology, science and technology.
Premium biofuels from straw – production of advanced biofuels using the Sylvan process
Authors: Aubrecht Jaroslav , Kubička David
Published: January 2021

The increasing demand for transportation fuels, especially middle distillates, stimulates the research of new strategies to obtain or synthesize biofuels. The processing of lignocellulosic biomass (for example straw) is a process of great interest, because after its hydrolysis and subsequent dehydration of the resulting sugar monomers, very valuable substances including furfural are obtained. Then, furfural is selectively hydrogenated to 2-methylfuran, sylvan, that is the basic “building block” in the Sylvan process. This manuscript summarizes the knowledge on Sylvan process as a promising way of biofuels synthesis. By sylvan condensing with aldehydes, ketones or even 2-methylfuran itself, it is possible to prepare C13-C16 oxygenates in high yields up to 100 % under mild reaction conditions (30 - 60 °C) over various heterogeneous catalysts. Based on the overview, the heterogeneous catalysts are preferred and the immobilized sulfonic acids are the most active catalysts, however, expensive. The reaction products then may be hydrodeoxygenated commonly over supported noble metal catalysts to provide premium quality C13-C16 hydrocarbons to produce diesel or kerosene. These fractions have great low-temperature properties such as CFPP (-50 °C) or cetane number (70-72). According to the proposed sustainability prediction, this process could be sustainable in the Czech Republic, where 30 % of produced wheat straw could be used for the production of 130 kt advanced biofuels by Sylvan process required by EU directive RED II. Finally, the future approaches have been suggested.
Recent Chalenges of indoor air quality
Authors: Skácel František , Tekáč Viktor
Published: January 2021

Indoor air pollution is a complex issue involving a wide diversity and variability of pollutants that threats human health. In this context, major efforts should be made to enhance indoor air quality. Thus, it is important to start by the control of indoor pollution sources. This review presents a general overview of single treatment techniques such as mechanical and electrical filtration, adsorption, ozonation, photolysis, photocatalytic oxidation, biological processes, and membrane separation. Since there is currently no technology that can be considered fully satisfactory for achieving ‘‘cleaner’’ indoor air, special attention is paid to combined purification technologies or innovative alternatives that are currently under research and have not yet been commercialized (plasma-catalytic hybrid systems, hybrid ozonation systems, biofilter-adsorption systems, etc.). These systems seem to be a good opportunity as they integrate synergetic advantages to achieve good indoor air quality. Review contains more than 150 references.
A Computationally Improved Heuristic Algorithm for Transmission Switching Using Line Flow Thresholds for Load Shed Reduction
Authors: Hussain Tanveer , Alam S M Shafiul , Hansen Timothy M. , Suryanarayanan Siddharth
Published: January 2021

We present a computationally improved heuristic algorithm for transmission switching (TS) to recover load shed. Research from the past showed that changing power system topology may control power flows and remove line congestion. Hence, TS may reduce the required load shed. One of the main challenges is to find a potential TS candidate in a suitable time. Here, we propose a novel heuristic method that is capable of finding the potential TS candidate faster than existing algorithms in literature. The proposed method is compatible with both the AC and DC optimal power flows (OPF). Three metrics are used to compare the proposed algorithm with the state-of-the-art from literature to show the speedup and accuracy achieved. The proposed method is implemented on the IEEE 30-bus system, PEGASE 89-bus system, IEEE 118-bus system, and Polish 2383-bus system. The results on the large-scale Polish 2383-bus system shows that the proposed algorithm is scalable to large real-world systems. Parallel computing is implemented to further improve the computational performance of the proposed algorithm.

The increasing growth of culinary service providers in Bandung has made competition in the culinary world even tighter. Service and product quality is the stake of every service provider to remain competitive in this industry. This study aims to find out, how are the form of service quality received by customers in the catering industry, the form of quality improvement efforts, and the form of handling customer complaints. This research was conducted in Alinea Catering, using qualitative descriptive methods. From the results of this study, it was found that basically the quality of services provided was still not good, with the determination of service standards that were deemed not optimal. This is because the standard setting has not been done in writing in a standard operating procedure. So this has an impact on the implementation of service quality and handling of complaints that cannot be measured with certainty. However, efforts to improve service quality have been well illustrated, by increasing employee education standards, increasing wages, and updating work uniforms regularly.

Employment Mobility and the Belated Emergence of the Black Middle Class
Authors: Lazonick William , Moss Philip , Weitz Joshua
Published: January 2021

As the Covid-19 pandemic takes its disproportionate toll on African Americans, the historical perspective in this working paper provides insight into the socioeconomic conditions under which President-elect Joe Biden’s campaign promise to “build back better” might actually begin to deliver the equal employment opportunity that was promised by Title VII of the Civil Rights Act of 1964. Far from becoming the Great Society that President Lyndon Johnson promised, the United States has devolved into a greedy society in which economic inequality has run rampant, leaving most African Americans behind. In this installment of our “Fifty Years After” project, we sketch a long-term historical perspective on the Black employment experience from the last decades of the nineteenth century into the 1970s. We follow the transition from the cotton economy of the post-slavery South to the migration that accelerated during World War I as large numbers of Blacks sought employment in mass-production industries in Northern cities such as Detroit, Pittsburgh, and Chicago. For the interwar decades, we focus in particular on the Black employment experience in the Detroit automobile industry. During World War II, especially under pressure from President Roosevelt’s Fair Employment Practices Committee, Blacks experienced tangible upward employment mobility, only to see much of it disappear with demobilization. In the 1960s and into the 1970s, however, supported by the Civil Rights Act and the Equal Employment Opportunity Commission, Blacks made significant advances in employment opportunity, especially by moving up the blue-collar occupational hierarchy into semiskilled and skilled unionized jobs. These employment gains for Blacks occurred within a specific historical context that included a) strong demand for blue-collar and clerical labor in the U.S. mass-production industries, which still dominated in global competition; b) the unquestioned employment norm within major U.S. business corporations of a career with one company, supported at the blue-collar level by mass-production unions that had become accepted institutions in the U.S. business system; c) the upward intergenerational mobility of white households from blue-collar employment requiring no more than a high-school education to white-collar employment requiring a higher education, creating space for Blacks to fill the blue-collar void; and d) a relative absence of an influx of immigrants as labor-market competition to Black employment. As we will document in the remaining papers in this series, from the 1980s these conditions changed dramatically, resulting in erosion of the blue-collar gains that Blacks had achieved in the 1960s and 1970s as the Great Society promise of equal employment opportunity for all Americans disappeared.

Published: January 2021

Zakat is the name or designation of something that a person gives to those who are entitled to it, meaning zakat is one of the pillars of Islam that deals directly with property and social conditions. One of the forms of wealth to which the zakat should be issued is the wealth of commerce. Prof. Dr. Wahbah Zuhaili in his book, “Al-Fiqh al-Islam waadillatuhu” describes the house when it comes to income / profit earned by renting / selling it is obligatory. The scholars explain that there is a zakat on real estate when selling a home. This is what was discussed at the second Muslim scholars in Cairo, that there is a zakat obligation on the profit or income of a home sale when it reaches nishab and is fulfilled when selling the house. Although he wants to buy a house again, he has to pay his charity first so that his wealth can be clean and be a blessing in life and in the hereafter.Keywords: Zakat, Mathematics,Home
Growers follow the label: An analysis of bee-toxic pesticide use in almond orchards during bloom
Authors: Durant Jennie L. , Goodrich Brittney K. , Chang Kelly T. , Yoshimoto Evan
Published: January 2021

California almond orchards are most U.S. beekeepers' first stop on their pollination and honey production circuit, so the agrochemicals bees are exposed to in almonds can shape the vitality of their colony for the rest of the year. We explored the potential for honey bee exposure to bee-toxic agrochemicals during almond bloom by utilizing the California Department of Pesticide Regulations' Pesticide Use Report database from 1990 to 2016. We found that overall, growers are observing the pesticide labels and reducing their use of labeled bee-toxic pesticides during almond bloom. However, we also found that insect growth regulators, fungicides and organosilicone surfactants — agrochemicals often not labeled as toxic to bees — are commonly applied during almond bloom. These agrochemicals can be sublethally or synergistically toxic to adult honey bees and bee larvae, presenting potential harm to colonies during almond pollination. Our findings demonstrate the need for a shift in the U.S. Environmental Protection Agency's labeling requirements, as well as continued communication between almond growers, pesticide applicators and beekeepers to keep colonies at a low risk of bee-toxic agrochemical exposure.

The study employed the standard questions for assessing theknowledge level of respondents. The questions test their understanding of simple and compoundinterest,inflation and portfolio diversification. For the spending behaviour, thePlanned Behaviour Theory(PBT) proposed by Icek Ajzen (1985) as a theoretical framework for measuring spending behaviour usingthe respondents preparation of budget and personal pre-retirement savings account as proxies. Data wascollected using a structured questionnaire . Descriptive statistics and multiple regression was used toanalyze thedata. The result showed that there is a positive correlation between the level of financial literacyand the spending behaviour of therespondents. The less the knowledge of financial management the peoplehave, the higher the risk of poor spendingbehaviour. The conclusion was drawn to say that more work isneeded to equip the youth especially on the art of financial management.

For each of the two participants in the game -state institutions and enterprises - proposed indicators determine the strategy of the game participant and theirbehavior in such a game. The content of each of the proposed indicators is considered and it is shown how theirvalue can be obtained. The proposed indicators for both participants in the game are leveled to a single scale.The indicators of the model of the antagonistic game between the enterprise and state institutions aredetermined that became the basis for the construction of the game model, which is a tuple. The developedmodel of the influence of state institutions on the enterprise economic security system, represented by acombination of possible strategies for the behavior of both participants in the game in hyper cubic fivedimensional space, which are expressed by the values of indicators for each of these participants, as well as thecalculated “gain” for each of these combinations. Using this model allows to achieve different resultsdepending on the goal of the study. The main result of the model is the search for a balance of interests in the“enterprise-state” system. That is, the search for those points of stable choice that can be obtained using thedeveloped model, namely: search for a local or general extremum in the game field, which will determine themaximum win for one of the participants or the total win of two participants at the same time; research andquantitative estimation of the actual and maximum possible negative impact of state institutions on theeconomic security system of business entities; determining the expected change in the influence of stateinstitutions on the economic security system of business entities due to changes in its strategy; theestablishment of the best strategy for a business entity in existing conditions, which, according to the selectedcriterion, will ensure the stable functioning of the economic security system at an enterprise; determination ofthe limits of the negative impact of state institutions on the economic security system of an enterprise.

Semakin berkembangnya dunia pigura di Indonesia saat ini, semakin banyak produk pigura baru yang muncul serta lebih menarik. Namun dengan semakin berkembangnya dunia pigura dan teknologi saat ini, tidak diimbangi dengan menjual produk pigura ini ke masyarakat luas secara online. Banyak masyarakat saat ini yang ingin membeli pigura harus datang terlebih dahulu ke toko secara offline dan calon pembeli hanya ditawarkan dengan produk pigura yang stoknya ada saja. Padahal pigura sangat banyak macamnya dan selalu digunakan oleh masyarakat untuk memasang foto kenangan, seperti kelulusan atau foto kenangan pernikahan di rumah.

Untuk menyelesaikan masalah tersebut, maka dibuatlah sebuah website penjualan pigura. Website ini akan dibuat menjadi dua bagian, yaitu website untuk admin perusahaan pigura dan website untuk customer. Website admin digunakan untuk memproses data master, pembayaran, input nomor resi, dan report sedangkan website customer digunakan untuk melakukan proses pemesanan pigura dan customization frame.

Dengan dibuatnya website ini diharapkan perusahaan pigura dapat menghemat biaya operasional dan memudahkan perusahaan pigura untuk mengenalkan, serta memasarkan produknya secara mudah. Website yang dibuat juga dapat membantu customer untuk melihat model frame dengan model yang terbaru, serta melakukan customization frame yang diinginkan dengan mudah.
Privilégio, poder e performatividade: a ética da matemática na sociedade e na educação
Authors: Ernest Paul , Da Cruz (tradutora) Danúbia Baltazar
Published: January 2021

Os benefícios indiscutíveis e as virtudes intrínsecas da matemática não deveriam provocar uma cegueira quanto ao possível dano colateral provocado pela sua imensa, impiedosa e destrutiva força**, que é capaz de fazer a educação e a sociedade se renderem em direção a um futuro reformulado. Por causa do grande poder da matemática e da sua influência por toda a sociedade, é preciso realizar uma auditoria ética. Este artigo conduz uma crítica ética considerando quatro aspectos inter-relacionados da matemática na educação e na sociedade e seus impactos negativos. O primeiro deles é a supervalorização da matemática e os efeitos que este poder tem em manter privilégios; em seguida, os poderosos impactos negativos que estudar matemática têm em muitos estudantes de modo individual; terceiro: as aplicações visíveis, porém problemáticas, da matemática dentro da sociedade, as quais são protegidas de críticas porque a matemática continua a ser vista como neutra; o último aspecto é os efeitos profundos e performáticos das aplicações ocultas da matemática reformatadoras da sociedade e modificadoras da vida cotidiana, mas mantidas sem verificação em qualquer sentido. A maior parte deste artigo é dedicada a revelar estes efeitos prejudiciais. As soluções propostas que estão aqui servem para fomentar a consciência ética no estudo de matemática em todos os níveis e também para desafiar o estereótipo generalizado da matemática como algo eticamente neutro.
