The number of mobile Medicare applications has grown exponentially over the past few years, and it is expected to continue to grow soon. The use of health apps promises to be a good way to improve patient care and make work easier for professional. However, some cases of malfunction or misdiagnosis and treatment recommendations have been reported. Regulation is essential to protect users and support product development. So, to suppress the malfunctions we present a pharmacopeia Medicare app in which the customer can see the original profile and the specification of any stimulant with its useful information. This inculcates a clean process which procures a less chance of misapplication of the drugs. These mobile medical app companies have improved access to clinical references and point of care tools. However, it is difficult to identify mobile medical apps that are suitable for the practice of pharmacy. This app is entirely based on our experience in accrediting websites with health-related content and journal.
Community structure of epigeic arthropods in barley (Hordeum vulgare L.) soils
Authors: Langraf Vladimír , Petrovičová Kornélia , Schlarmannová Janka
Published: December 2021

Aim of study: The study of epigeic arthropods provides information on how ecosystems respond to different management practices. Changes in the structure of epigeic groups reflect changes in the ecological status of habitats. We assessed the influence of semi-natural habitats and environmental variables on the dispersion of the epigeic groups.
Area of study: Southwestern part of Slovakia
Material and methods: Between 2018 and 2020, six barley (Hordeum vulgare L.) fields were selected each year. Five pitfall traps were placed on each field and environmental variables (soil pH and moisture, light conditions, soil N, P, K) were analysed. We collected 8,730 individuals belonging to 14 taxonomic groups. The variables of the study sites (habitat, locality name, cadastral area, altitude, coordinates of localities) were also analysed.
Main results: We observed a decrease in the average number of individuals in the direction from pitfall traps 1 (semi-natural areas) to 5 (barley crop) between July and August. The number of individuals was similar in May and June. The dispersion of epigeic arthropods was affected by soil moisture, pH soil, phosphorus, potassium and nitrogen. In the beetles model group, which was represented by the highest number of individuals, we confirmed an increasing number of individuals with increasing values of K, P, N and soil moisture. The neutral pH of the soil was optimal for beetles.
Research highlights: The ecotone rule does not apply during all months, so we have contributed new information about the ecotone rule. Agricultural intensification affects soil arthropods, a taxonomic group with an important role in the functioning of agricultural ecosystems.

KUDA JAWA DAN GAJAH SIAM PEREKAT HUBUNGAN JAWA-SIAM
Authors: Supardi Nunus
Published: December 2021

Negeri Siam atau Thailand sekarang, sangat tertarik pada kebudayaan Nusantara, khususnya Jawa. Tarian, musik, batik, cerita Panji, dan bahasa Jawa sangat dikenal di Siam. Di Siam cerita Panji dari Kediri telah diperlakukan sebagai cerita drama yang disakralkan dengan dengan nama, Inao. Selain tertarik pada mata dagang rempah-rempah, kayu cendana, dan kapur barus, ternyata Siam juga tertarik pada kuda Jawa. Masalahnya, belum banyak orang yang mengetahui bahwa kuda Jawa juga pernah menjadi mata dagang yang penting. Selain itu, belum banyak diketahui bahwa kuda juga dijadikan cenderamata bergengsi untuk diberikan kepada Raja Siam. Sebaliknya, Raja Siam menjadikan hewan gajah yang dimitoskan sebagai hewan suci sebagai cenderamata untuk Raja Jawa. Tujuan kajian ini adalah agar masalah jual-beli dan saling tukar cenderamata kuda dan gajah antara Jawa-Siam dapat membuka wawasan kita bahwa kuda dan gajah menjadi benih  dalam membangun  persahabatan  kedua bangsa. Melalui metode kajian berdasarkan pada sumber pustaka di Siam dan VOC serta sumber lainnya diketahui bahwa selain budaya, sejak beberapa abad yang lalu kuda Jawa telah ikut menjadi daya tarik bagi raja-raja Siam untuk datang ke Jawa. Sebaliknya, Siam menjadikan gajah sebagai cenderamata bagi Jawa. Kedua hewan itu telah ikut menjadi “lem perekat” bagi kedekatan hubungan antara kedua bangsa dari dulu hingga kini.

“Los primeros a parar y los últimos a volver”: los trabajadores de la cultura en Brasil en tiempos de COVID-19
Authors: Avellar de Muniagurria Lorena
Published: December 2021

En este ensayo, discuto la situación vivida durante la pandemia del COVID-19 por personas que trabajan en el área cultural en Brasil. Primeramente, caracterizo el sector cultural mostrando su participación en la economía brasileña y las desigualdades que históricamente lo constituyen. Veremos que, a pesar de su importancia simbólica y económica, trata-se de un sector laboral con altos índices de informalidad que, mismo antes del COVID-19, enfrentaba un aumento de precarización bien como un ambiente de creciente intolerancia y censura. En la segunda parte del ensayo, trato del contexto de la pandemia y sus consecuencias para los trabajadores de cultura, haya visto ser este uno de los primeros grupos “a parar” y de los últimos que irán a volver a sus actividades. Discuto como las acciones de emergencia desarrolladas hasta el momento para el sector, si bien importantes, no alcanza a solucionar el problema y, en algunos casos, llegan incluso a reforzar desigualdades preexistentes. Finalizo con una breve reflexión sobre los futuros que se dibujan y la necesidad de desarrollar nuevas herramientas de análisis y observación que permitan pensar los modos de existencia en escenarios de precariedad y “fin del mundo” como los que se presentan hoy día.
Breve exploración de los efectos sociales y económicos de la pandemia Covid-19 en la Agricultura Campesina en Paraguay
Authors: Riquelme Quintín
Published: December 2021

El ensayo tiene como propósito reflexionar sobre la agricultura campesina en el contexto de la crisis generada por el Covid-19 en Paraguay. Se sostiene que el efecto de la pandemia en la agricultura campesina tiene otras connotaciones y características por ser una actividad autónoma, desarrollada en el ámbito familiar y cuya finalidad principal es la producción de alimentos. Siendo esta su característica, no solo pudo soportar mejor la crisis sino al mismo tiempo contribuyó con su aporte a paliar en parte la carencia de alimentos a pobladores de barrios urbanos de varios municipios del país. La pandemia visibiliza la relevancia de la agricultura campesina por ser productora de alimentos diversificados y a la vez refuerza la importancia de la tierra como factor de producción y de reproducción de la vida. Es de esperar que esta crisis producto del Covid-19 modifique la percepción y la visión sobre la agricultura campesina como algo residual y que las políticas públicas la contemple como un componente fundamental de la seguridad y soberanía alimentaria nacional.

Authors: Schewe Lelia
Published: December 2021

El COVID-19 causó profundas reorganizaciones en las dinámicas sociales de nuestros países. Algunos trabajos sobre colectivos vulnerados han manifestado que el aislamiento social ya estaba instalado antes de la necesidad de ser preventivo y obligatorio, porque se construyeron prácticas violentas, que actúan como motivos de exclusión.Entre esos colectivos, las personas con discapacidad, han sido obligadas a aislarse por sus discapacidades o bien, han tenido que permanecer separadas, porque las barreras existentes en sus entornos inmediatos no les permiten desplazarse, para construir una vida plena, autónoma, con participación en las comunidades.En este ensayo se pretende comunicar algunas experiencias en el contexto de nuestra vecindad transfronteriza, desde la provincia de Misiones y las reflexiones que comenzamos a tejer desde el compromiso social de los investigadores de varias universidades de Argentina para superar esos otros aislamientos.

Authors: Paredes Olga
Published: December 2021

Este ensayo tiene como objetivo reflexionar sobre los nuevos desafíos para el fortalecimiento democrático que enfrenta la Universidad como institución, en medio de la crisis producida por la pandemia de la COVID-19. Vivir esta pandemia en la era digital puede ser una amenaza o una oportunidad. La COVID-19 se presenta como una guerra, lo que pone en peligro el desenvolvimiento democrático de las relaciones. Los efectos del virus, se expanden no sólo a nivel físico, sino también mental y social. Reflexionamos a partir de algunos datos arrojados por un diagnóstico aplicado a 968 personas de la comunidad académica de la Universidad Metropolitana de Asunción, a efectos de conocer sus realidades en situación de COVID-19. Entre los resultados, encontramos insuficiente conocimiento para el cuidado de la salud mental, pero un alto deseo de participación y solidaridad en medio de la crisis. Uno de los nuevos desafíos que se presentan para la Universidad, tiene que ver con el desarrollo de procesos adaptativos a la crisis actual desde un enfoque democrático, en el que se promuevan los derechos humanos a la salud mental y a la participación, a través del fomento de la inclusión digital.
El papel de las Ciencias Sociales frente a la intención de una reforma neoliberal del Estado paraguayo
Authors: Ovando Luis Alexander
Published: December 2021

La post-pandemia traerá consigo una serie de cambios en lo económico, político y social. Queda claro que habrá un antes y un después luego de la crisis sanitaria y que muchas de las modificaciones que vendrán, se darán en el campo de la administración pública. En lo que respecta a Paraguay, no es la excepción, el gobierno puso en marcha la reforma “estructural” del Estado, y en ella se aprecia una fuerte agenda neoliberal que como de costumbre, busca acompañar intereses empresariales por sobre otros. En este sentido y atendiendo que la emergencia sanitaria producirá considerables daños al tejido comunitario, el papel de las Ciencias Sociales en este contexto será de vital importancia, por un lado, para guiar las próximas medidas políticas hacia un enfoque más humano y por otro lado, para pensar en nuevos y mejores escenarios sociales posterior al COVID-19.

Published: December 2021

Based on the structural analysis of complex hydrochemical indices for assessing surface water pollution used in various river basins, and the laws of limiting factors, a mathematical model was obtained in the form of the maximum permissible water pollution coefficient (Kпдзi), representing the product of the water content coefficient (Kb) and the maximum water pollution (Kпзi), by based on the laws of nature, principles and properties of natural processes in, together with the water pollution index (ИЗВ), are used for the geoecological assessment of the surface water quality of the Ile River basin on a spatial-temporal scale, taking into account the regulatory criteria for maximum permissible concentrations of pollutants for fishery water bodies, that between the coefficient of the maximum permissible water pollution (Kпдзi) and the water pollution index (ИЗВ) there is a pronounced relationship, described by a logarithmic equation, allowing them to be used to assess the ecological state water bodies. Water quality assessment was carried out for four hydrological sections of the Ile River catchment basin, which showed that water pollution is of a transboundary nature, since at the Dobyn hydrological station, located on the borders of the Republic of Kazakhstan and the People's Republic of China, the water quality is «polluted», and from the Kapshagai reservoir to Lake Balkhash «moderately polluted», where due to the selfcleaning ability of the aquatic ecosystem and the waters coming from the tributaries, there is some improvement in water quality.

Authors: Tuấn Lê Anh , Thụy Nguyễn Ninh , Khoa Nguyễn Tấn
Published: December 2021

Nghiên cứu sử dụng chất tạo khí hydrogen peroxide (H2O2) kết hợp với tro bay và xỉ đáy nhằm hoạt hóa trong môi trường geopolymer. Thành phần xỉ đáy sử dụng với hàm lượng 20 % đến 100 % trong cấp phối vữa. Kết quả thực nghiệm cho thấy thành phần dung dịch hoạt hóa với tỷ lệ 0,4 đến 0,8 với tro bay có tác dụng làm tăng độ linh động đến 70 % cho vữa geopolymer và cường độ nén tăng đến 50 %. Vữa geopolymer dùng xỉ đáy thay thế hoàn toàn cát làm tăng độ linh động đến 30 % và thời gian chảy đạt khoảng 10 giây đến 11 giây. Tuy nhiên cường độ hoạt hóa có xu hướng giảm đến 40 %. Chất tạo bọt H2O2 sử dụng với hàm lượng 1 % đến 5 % có khả năng làm việc với môi trường dung dịch hoạt hóa làm cho vữa có khả năng phồng nở đến hơn 40 %. Quá trình hoạt hóa cho thấy cường độ của bê tông phụ thuộc vào hàm lượng chất tạo bọt và hàm lượng dung dịch hoạt hóa. Việc sử dụng kết hợp chất tạo bọt H2O2 và tro bay – xỉ đáy có khả năng chế tạo bê tông nhẹ theo công nghệ geopolymer.

Pacific Universities’ Leadership during the COVID-19 Pandemic- a Case Study of Fiji and New Zealand
Authors: Goundar Prashneel Ravisan , Sharma Sherita
Published: December 2021

The global education system came under scrutiny in 2020 due to the unexpected pandemic. COVID-19 forced higher education institutions everywhere to rethink the way to deliver classes or continue offering their services due to travel restrictions, lockdowns and social distancing policies. This caused major disruptions in carrying out normal teaching and learning. The intervention of university leadership in maintaining decorum during the pandemic entailed making pivotal decisions within a short period of time. The aim of this paper is to highlight various statements made by a group of universities from Fiji and New Zealand to present their position, and policies during the global pandemic. This article discusses how university leaders in the South Pacific with a case study of Fiji and New Zealand have responded to the pandemic. It discusses the statements and media releases of university leaders in Fiji (a developing nation) and New Zealand (a developed nation), particularly their responses and comments on the mode of teaching, international travel, social distancing, financial impact, and research. These focus areas need to be priority for university leaders in making crucial decisions in operating higher education institutions during unexpected events such as the pandemic.

Authors: Ferreira  Oliveira Ana Elisa , Pereira Arnaldo César , Ferreira Lucas Franco
Published: December 2021

The purpose of this work was the fabrication of a conductive carbon nanotube (CNT) ink. The proposed CNT ink remained remarkably stable over several months. The method includes combining the covalent and non-covalent functionalization, resulting in ink that exhibits excellent storage stability. The covalent functionalization was performed in the acid medium using H2SO4 and HNO3, while the non-covalent functionalization used sodium dodecyl sulfate (SDS) and ultrasonication. The materials were characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), electro­chemical impedance spectroscopy (EIS), and cyclic voltammetry (CV). FTIR and SEM confirmed that at the non-covalent functionalization, SDS was successfully adsorbed on the f-CNT surface, while at the covalent functionalization, the functional groups (-COOH, C=O and -OH) were inserted into the CNT surface. Voltammetry and EIS indicated that SDS in the presence of functional groups facilitates electron transfer by improved electrical conductivity. The final product was a well-dispersed CNT ink with an average ohmic resistance of 18.62 kΩ. This indicates that CNT ink can be used in the fabrication of electrochemical sensors.
SOME COMMENTS ON THE INTERPRETATION
OF THE TRIBOLOGICAL WEAR COEFFICIENT
Authors: Sadowski Jan
Published: December 2021

An original model of tribological wear is presented, an alternative to the commonly used J.F. Archard’s model.
The impossibility is established of a full conversion of mechanical work into the heat of dissipation and
thereby of avoiding wear in the sliding friction of solids. The assumption is consequently questioned that only
some contacts of surface asperities are subject to temporary wear. Material wastage is assumed to occur at
each contact of asperities. The volume of worn material is dependent on the volumetric wear coefficient of
the “energy dissipation zone” in friction. The dimensions of the zone are determined in both the elements in
friction. Linear wear intensities and volumetric wear are described in analytical terms. The thermodynamic
analysis of the tribological process indicates some limitations to these intensities. Energetic efficiencies of
solid wear and heating as a result of friction are defined. Some new interpretations of the wear coefficient are
proposed.
Anmeldepflichten nach § 39a GWB
Authors: Brinker Ingo , Haag Kathrin
Published: December 2021

The 10th Amendment introduced Section 39a into the Act against Restraints of Competition (GWB). It gives the Bundeskartellamt the power to impose on individual companies identified by the Bundeskartellamt the obligation to notify proposed mergers to the Bundeskartellamt, even if the thresholds in Section 35 GWB are not met. This imposes considerable additional burden on the companies concerned, which need to be justified. This book deals with the legal framework of the new provision, the constitutional objections to it as well as the requirements that must be met for the Bundeskartellamt to issue an order.

Published: December 2021

Several biologically active substances representing the bone deposition and resorption processes are released following damage to periodontal tissue during orthodontic movement. Biomarkers are by definition objective, quantifiable characteristics of biological processes. The analysis of saliva/salivary fluid and Gingival crevicular fluid (GCF) may be an accepted way to examine the ongoing biochemical processes associated with bone turnover during orthodontic tooth movement and fixed orthodontic treatment pain. Assessing the presence of these salivary physiological biomarkers would benefit the clinician in appropriate pain diagnosis and management objectively of various problems encountered during the orthodontic procedures and for better outcome of biomechanical therapy. Due to lack of standardized collection procedure, even though well accepted by patients, saliva is often neglected as a body fluid of diagnostic and prognostic value. A literature search was carried out in major databases such as PubMed, Medline, Cochrane library, Web of Science, Google Scholar, Scopus and EMBASE for relevant studies. Publication in English between 2000 to 2021 which estimated Saliva markers as indicators of orthodontic tooth movement was included. The list of biomarkers available to date was compiled and is presented in table format. Each biomarker is discussed separately based on the available and collected evidences. Several sensitive salivary and GCF biomarkers are available to detect the biomechanical changes occurring during orthodontic tooth movement and pain occurring during fixed orthodontic therapy. Further focussed research might help to analyze the sensitivity and reliability of these biomarkers or cytokines, which in turn can lead to the development of chairside tests to assess the pain experienced by patients during orthodontic therapy and finally the outcome of the fixed orthodontic therapy.

Published: December 2021

Confidentiality and Integrity are two paramount objectives in the evaluation of information and communication technology. In this chapter, we propose an arithmetic approach for designing asymmetric key cryptography. Our method is based on the formulation of cyclotomic matrices correspond to a diophantine system. The strategy uses in cyclotomic matrices to design a one-way function. The result of a one-way function that is efficient to compute, however, is hard to process its inverse except if privileged information about the hidden entry is known. Also, we demonstrate that encryption and decryption can be efficiently performed with the asymptotic complexity of Oe2.373. Finally, we study the computational complexity of the cryptosystem.
Extracellular Vesicles and Their Interplay with Biological Membranes
Authors: Yeo Xian Ping Jacob , Raj Neupane Yub , Pastorin Giorgia
Published: December 2021

Most cells secrete vesicles into the extracellular environment to interact with other cells. These extracellular vesicles (EVs), have undergone a paradigm shift upon the discovery that they also transport important material including proteins, lipids and nucleic acids. As natural cargo carriers, EVs are not recognised by the immune system as foreign substances, and consequently evade removal by immune cells. These intrinsic biological properties of EVs have led to further research on utilising EVs as potential diagnostic biomarkers and drug delivery systems (DDSs). However, the internalisation of EVs by target cells is still not fully understood. Moreover, it is unclear whether EVs can cross certain biological membranes like the blood-brain barrier (BBB) naturally, or require genetic modifications to do so. Hence, this review aims to evaluate the relationship between the composition of EVs and their association with different biological membranes they encounter before successfully releasing their cargo into target cells. This review identifies specific biomarkers detected in various EVs and important biological barriers present in the gastrointestinal, placental, immunological, neurological, lymphatic, pulmonary, renal and intracellular environments, and provides a recommendation on how to engineer EVs as potential drug carriers based on key proteins and lipids involved in crossing these barriers.
Harnessing Beneficial Plant-Microbe Interactions for Enhanced Plant Adaptation to Abiotic Stresses
Authors: Makaza William , Nyaradzai Kamutando Casper
Published: December 2021

Boosting crop production is a vital venture for enhancement of humanity. However, it remains a dream, especially in developing countries. To attain food security at household level, productivity is constrained by a several biotic and abiotic stresses. Yield losses are usually influenced by abiotic stresses, particularly drought and heat stress, and poor soil fertility. Optimal crop production under these stress factors requires substantial inputs, including irrigation and heavy fertilization, strategies which majority of farmers in poor countries lack capacity to exploit. Therefore, much more sustainable and accessible alternatives need to be developed in order to address the problem of food insecurity. Recently, research has proven that plant adaptation to abiotic stresses can be promoted by beneficial microbial species, especially those that reside in the rhizosphere. For instance, mycorrhizal fungi have been found to expand the root system of plants to access more water and nutrients. In-depth understanding of the mechanisms underlying beneficial plant-microbe interactions is key in development of holistic programs for boosting yields under abiotic stress conditions. This chapter seeks to unravel the mechanisms underlying beneficial plant-microbe interactions and the importance of these interactions in stress-adaptation.

The emergence of Coronavirus Disease 2019 (COVID-19) in late 2019 has brought great challenges to public health worldwide and, to date, there is no specific approved therapeutic protocol. Therefore, this chapter will analyze types of intervention for use in patients with COVID-19 developed by American researchers from records made on the Clinical Trials platform. For the search strategy, keywords “COVID-19” in the “Condition or Disease” section and “United States” in the “Country” section were used. No filters were applied. Data were descriptively analyzed. In total, 1,182 studies were obtained, of which 496 met the eligibility criteria. Sample size ranged from 1 to 10,000 participants. Most studies involved the age group of 18–64 years (48.6%). As for design, randomized type (80.5%), parallel (75.6%), open designs (38.7%) and those with therapeutic purpose (88.3%) were more frequent. Most clinical trials used the two-arm trial (67.3%), researched drugs (64.8%), used placebo (55.2%) and were sponsored by pharmaceutical/biotechnology companies (35.4%). Clinical trials developed by American researchers on COVID-19 involve adult and elderly participants, with predominance of randomized, parallel and open design, for therapeutic purposes and mostly evaluated immunosuppressants or combinations of antivirals/immunosuppressants. The drugs and biological products Remdesivir, Baricitinib in combination with Remdesivir, Bamlanivimab and Etesevimab, REGEN-COV and COVID-19 convalescent plasma were also used, authorized for emergency use.
