Background

Hospital stays after major surgery are shorter than ever before. Although enhanced recovery and early discharge have many benefits, some complications will now first manifest themselves in home settings. Remote patient monitoring with wearable sensors in the first days after hospital discharge may capture clinical deterioration earlier but is largely uncharted territory.

Objective

This study aimed to assess the technical feasibility of patients, discharged after esophagectomy, being remotely monitored at home with a wireless patch sensor and the experiences of these patients. In addition, we determined whether observing vital signs with a wireless patch sensor influences clinical decision making.

Methods

In an observational feasibility study, vital signs of patients were monitored with a wearable patch sensor (VitalPatch, VitalConnect Inc) during the first 7 days at home after esophagectomy and discharge from hospital. Vital signs trends were shared with the surgical team once a day, and they were asked to check the patient’s condition by phone each morning. Patient experiences were evaluated with a questionnaire, and technical feasibility was analyzed on a daily basis as the percentage of data loss and gap durations. In addition, the number of patients for whom a change in clinical decision was made based on the results of remote vital signs monitoring at home was assessed.

Results

Patients (N=20) completed 7 days each of home monitoring with the wearable patch sensor. Each of the patients had good recovery at home, and remotely observed vital signs trends did not alter clinical decision making. Patients appreciated that surgeons checked their vital signs daily (mean 4.4/5) and were happy to be called by the surgical team each day (mean 4.5/5). Wearability of the patch was high (mean 4.4/5), and no reports of skin irritation were mentioned. Overall data loss of vital signs measurements at home was 25%; both data loss and gap duration varied considerably among patients.

Conclusions

Remote monitoring of vital signs combined with telephone support from the surgical team was feasible and well perceived by all patients. Future studies need to evaluate the impact of home monitoring on patient outcome as well as the cost-effectiveness of this new approach.
An experimental study on variability of deformation characteristics of concrete in compression
Authors: Plyusnin Mixail G. , Tsybakin Sergey V.
Published: October 2020

Introduction. An experimental study on variability of deformation characteristics of concrete and an assessment of its influence on the bearing capacity of eccentrically compressed reinforced concrete elements were performed. In pursuance of effective regulatory documents, a non-linear deformation model was applied to perform the strength analysis of standard cross sections of reinforced concrete structures. The application of this method in probabilistic design is also of interest. Analytical functions approximating the true σ–ε diagram, made for concrete, use strength and deformation characteristics of concrete as parameters. However, variability of deformation characteristics of concrete has not been sufficiently studied, although it may have significant influence on results of analyses.

Materials and methods. Complete σ–ε diagrams were made for uniaxially compressed concrete to solve this problem. These diagrams were applied to numerically assess the influence of variability of deformation characteristics of concrete on the bearing capacity of an eccentrically compressed reinforced concrete element in terms of its standard cross section. A non-linear deformation model was used to identify the bearing capacity.

Results. The experiment has proven substantial variation of diagram shapes within the same strength class. The influence of the εb0 value of ultimate deformations of concrete on the bearing capacity is demonstrated for a standard cross section as a result of the strength analysis of an eccentrically compressed reinforced concrete element. The strength analysis was performed by applying experimental σ–ε diagrams made for uniaxially compressed concrete.

Conclusions. The analysis of the findings has shown that the value of ultimate deformations of concrete exposed to uniaxial compression affects the bearing capacity of eccentrically compressed reinforced concrete elements. The degree of influence depends on concrete strength, reinforcement percentage and the eccentricity of a longitudinal force.

Published: October 2020

Las relaciones existentes entre la sociedad y los ecosistemas naturales son complejas y es necesario entenderlas para emprender acciones que contribuyan a un manejo sustentable. Con el objetivo de evaluar la influencia de algunas actividades antropogénicas sobre los ecosistemas que integran el Ãrea Natural Protegida Sierra Fría se condujeron 20 entrevistas, 10 de ellas dirigidas a propietarios y 10 a los manejadores de los predios. El formato de entrevista incluyó los tiempos: pasado, presente y futuro, para analizar las actividades y fenómenos causantes de las alteraciones en el paisaje. Se realizaron análisis radiales para observar las principales amenazas y detectar los recursos bióticos más usados. Los resultados muestran que los disturbios más fuertes disminuyeron en las décadas de los 70 y 90 del siglo XX. Actualmente, la extracción de leña muerta, cacería cinegética y los saneamientos forestales, son las actividades de manejo más importantes, mientras que las principales amenazas son la fragmentación del hábitat y la extinción de fauna silvestre. Los recursos bióticos más usados son la fauna silvestre y los encinos (Quercus spp.), madroños (Arbutus spp.) y táscates (Juniperus spp.), como recursos maderables.  Los resultados obtenidos servirán para diseñar estrategias de manejo con una visión socio-ecosistémica en la Sierra Fría, Aguascalientes.

La protesta social como acción irregular. Vigencia de la figura del partisano en la mirada policial sobre los manifestantes piqueteros en Argentina
Authors: Perelman Marcela
Published: October 2020

Este trabajo trata un aspecto de la criminalización de la protesta social: formas criminalizantes en que los funcionarios policiales ven a los manifestantes piqueteros en Argentina. A partir del trabajo de C. Schmitt sobre la figura del partisano y basado en conversaciones con policías, documentación interna de instituciones de seguridad y de la observación del trabajo policial durante las acciones de protesta, aquí se identifican los rasgos y presupuestos que operan en las formas en que los funcionarios policiales conceptualizan a los manifestantes piqueteros y sus prácticas de protesta. Así, se logra reconstruir la mirada policial sobre ellos con importantes niveles de recurrencia y consistencia, destacándose las ideas de “ejércitos irregulares” y “combates contra partisanos”, como elementos presentes del pensamiento policial.

Strategic investment decision-making: A theoretical perspective
Authors: Elmassri Moataz , Abdelrahman Mahmoud , Elrazaz Tariq
Published: October 2020

There is a stream of research that has introduced strategic investment decision-making (SIDM) through case studies and organisation-based fieldwork. However, a systematic theorisation around SIDM processes and practices still under-presented in the literature. This research aims to show how strong structuration theory (SST) could be used as an appropriate theoretical lens to explore how SIDM studies are theorised and conducted. Through employing the parameters and the concepts of SST within the SIDM context, we found that SID is a judgemental decision that is constructed by various influences. SIDs are not isolated from the social, political, and economic aspects. Subjective judgements and the decision-makers’ intuition are crucial throughout the process of SIDM. Therefore, SIDs cannot be abstracted as an objective decision-based on applying investment appraisal technical methods. The theoretical lens presented in this paper will enable researchers to drill down into the ‘ontic’ level to empirically explore in-depth the complex interrelationships between various agents and structures which, arguably, fits the SID context. Furthermore, this paper will help scholars understand how SID is made from SST perspective and guide them to conduct future research to build on and also help executives to be guided by

Published: October 2020

The electric regulation capacity of heating units has been constantly improving due to the promotion of the heating units? flexibility transformation. This improvement has effectively alleviated the long remained serious wind and light abandonment phenomena in the heating season in China. In this paper, we discussed the key technologies of the low pressure zero output heating mode and bypass heating mode, both of which are widely used in thermo-electric decoupling. Moreover, the coupling transformation of the two heating modes has been successfully realized in a heating unit. The electric regulation capacity of the unit has been greatly improved, from 18.6% before the transformation to 66.7%, and the minimum technical output has been also reduced to 14.2% THA. After the transformation, the unit now is able to provide several heating modes with its operational flexibility greatly improved. By comparing the economical efficiency of these heating modes, we obtained the operation mode with the lowest heat rate. This transformation mode provides a huge grid space for the consumption of clean energy, so it is of positive reference value and exemplary significance in implementing the flexibility transformation of heating units.
Simplified logistics model and its application in process simulation
Authors: Chen Yiwei , Ding Guanliang , Bai Yakai
Published: October 2020

In order to solve the problem of complex calculation of logistics value in process simulation, based on the parameter characteristics of ASPEN PLUS, a simplified logistics calculation model is proposed. The comparison with exercom shows that the error of the calculation results in this paper is less than 1%, which verifies the correctness of the model. The calculation model of logistics flow provides convenience for process simulation software ASPEN PLUS to analyze the simulation process. Based on the logistics calculation model and the ?fuel cost? model of thermal economics, a coal-fired boiler of a domestic unit is analyzed. The results show that the heat loss of the boiler mainly occurs in the process of coal decomposition and combustion, followed by the heat exchange process between flue gas and main heat exchange surface. The overall efficiency of the boiler is 46.4%.
Differentiating MHC-dependent and -independent mechanisms of lymph node stromal cell regulation of proinsulin-specific CD8+ T-cells in type 1 diabetes

Published: October 2020

Lymph node stromal cells (LNSC) are essential
for providing and maintaining peripheral self-tolerance of potentially
autoreactive cells. In type 1 diabetes, proinsulin-specific CD8+T-cells,
escaping central and peripheral tolerance, contribute to beta-cell destruction.
Using G9Cα-/-CD8+T-cells specific for proinsulin, we
studied the mechanisms by which LNSC regulate low-avidity autoreactive cells in
the nonobese diabetic (NOD) mouse model of type 1 diabetes. Whereas MHC-matched
NOD-LNSC significantly reduced G9Cα-/-CD8+T-cell cytotoxicity
and DC-induced proliferation, they failed to sufficiently regulate T-cells
stimulated by anti-CD3/CD28. In contrast, non-MHC matched, control C57BL/6
mouse LNSC suppressed T-cell receptor engagement by anti-CD3/CD28 via
MHC-independent mechanisms. This C57BL/6-LNSC suppression was maintained even
after removal of the LNSC, demonstrating a direct effect of LNSC on T-cells,
modifying antigen sensitivity and effector function. Thus, our results suggest that a loss of NOD-LNSC
MHC-independent suppressive mechanisms may contribute to diabetes development.

Mobil robotlarla ilgili çalışmalarda, uygulamalar fiziksel ve simülasyon temelinde ortaya çıkmaktadır. Fiziksel oluşumların maliyet, materyal temini ve zaman kaybı gibi durumları uygulamaların simülasyon ortamında yapılması yönelimini arttırmıştır. Simülasyon çalışmalarında ise önemli nokta gerçek sistemin davranışlarını temsil edebilecek matematiksel modelin oluşturulmasıdır. Matematiksel model ise DC motorlar üzerine oluşturulmaktadır.DC motorların veri sayfalarında gerekli parametrelerin bulunmaması veya kısıtlı olması parametrelerinin deneysel ölçümlerle elde edilmesine neden olmuştur. Deneysel ölçümler için kurulan düzenekler ise genellikle laboratuvar ortamındadır ve karmaşık, materyal temini zor ve maliyetli düzeneklerdir. Ancak son yıllarda geliştirilen geliştirme kartları sensörler daha basit deney düzeneklerini kurma imkânı sağlamaktadır. Bu çalışmada geliştirme kartı ve sensörler ile oluşturulan deney düzeneği aracılığıyla motorun PWM sinyali, devir sayısı, açısal hızı elde edilmiş, sisteme bağlanan multimetre veya ölçüm sensörleri ile motor akımları, gerilimleri ölçülmüştür. Belirli aralıklarla alınan ölçüm değerlerine göre eğri uydurma, Newton – Kirschoff gibi yöntemlerle tork sabiti, emk sabiti, sürtünme, endüvi direnci gibi parametreler elde edilmiştir. Bulunan parametreler Matlab\Simulink ortamında test edilmiştir.
MICROCLIMATIC MONITORING IN MOUNTAIN-DEPRESSION LANDSCAPES

Published: October 2020

Monitoring is a continuous process of observing and registering the parameters of an object, in comparison with specified criteria. In recent decades, questions related to changes in climatic characteristics have been of great interest. Since 2007, microclimatic observations have been carried out automatically in the mountain-depression landscapes of the Baikal region. The correctness of the use of atmospheric-soil measuring systems is shown by comparing the data of automatic measurements and the data of standard meteorological instruments used at the weather stations of Roshydromet. Estimates of the temperature and humidity regime of air and soils were obtained at 72 sites located in different landscapes in the altitude range of 450–2300 m above sea level. The influence of landscape characteristics, primarily altitudinal zonality, is manifested in the monthly and annual values of meteorological characteristics. Calculations of the vertical gradient of air temperature on the slopes of the mountains are carried out. As a result, an assessment was made of the characteristics of temperature inversions, a phenomenon unique in its power in Eastern Siberia. Their intensity, duration, and frequency were estimated. A comparison is made of the temperature regime of soils under natural and anthropogenically disturbed conditions. The obtained measurement data are used to validate the results of climate modeling and remote sensing (satellite images). The best convergence of rows is observed in open, moderately humid areas. Microclimatic observation data make it possible to study in detail the temperature and humidity regime of landscapes, taking into account the altitudinal zonality, exposure and steepness of slopes throughout the year. The observational data obtained make it possible to clarify the climatic description of the study area, which is currently based mainly on the data of weather stations, the network of which does not cover mountainous regions.
MODELING OF THE CARBON AND NITROGEN CYCLES OF TUNDRA IN THE HOLOCENE
Authors:   A.M. Obukhov Institute of atmospheric physics, RAS, Arzhanov M.M.
Published: October 2020

The observed increase in near-surface temperature can cause degradation of permafrost and an increase in greenhouse gas emissions. At the same time, the productivity of the tundra increases, and more intense photosynthesis means an increase in the absorption of carbon from the atmosphere. Therefore, the development of models of the carbonnitrogen cycle to study the contribution of tundra ecosystems is a special challenge. In this work, the modeling of carbon and nitrogen dynamics in tundra ecosystems of northern regions of Western Siberia were carried out using the reservoirflow model including vegetation, organic carbon compounds, dissolved organic and inorganic nitrogen. Input data of the atmospheric forcing were set according to the results of calculations with CLIMBER-2 model for the last 10 thousand years. Model estimates show a regional increase in mean annual air temperature and a decrease in the annual range over a period of 10–5.5 thousand years ago due to an increase in winter temperatures in this region. According to the results of calculations, carbon stocks in soil increase monotonically during the period under consideration. Calculated soil C values for modern climatic conditions are 14700 gC/m2 . The reserves of nitrate and ammonium forms of nitrogen are stabilized at the beginning of the calculation period. The results of calculations show that tundra ecosystems within the last 10 thousand years, including those under conditions of near-surface warming with increasing winter temperature and minor changes in summer temperature could accumulate organic matter, absorbing carbon-containing greenhouse gases from the atmosphere.

The article contains the results of studying the morphological, electrolyte composition and acid-base status of the blood of service dogs of the German shepherd breed of different types of use, including the features of animals in the search for narcotic and explosive substances. 30 healthy dogs aged from 1 year to 6 years were studied. The problem of assessing the health of service dogs in the search for dangerous substances is updated. It is shown that drug-seeking German shepherds are characterized by a lower number of white blood cells, 13–20 % lower than in dogs of another profile, eosinophils in the leukogram. They have hyperkalemia and phosphatemia, with a pH of 7.44 and a low alkaline blood reserve. In mine-hunting dogs in the leukogram, the largest number of neutrophils, over 76 %, the proteinogram with signs of stress of the immune status is violated, with a high level of gammaglobulins, 50 % higher than normal. The acid-base status is shifted similarly to the comparison group. The concentration of inorganic phosphates in the electrolyte profile is 20 % higher than the reference intervals. The results prove the high psycho-emotional load of service dogs when searching for toxic substances, and the probabilistic influence of narcotic and explosive substances in the course of search activities.

The purpose of this work is to comprehensively study the ecological and geological conditions and results of monitoring studies of the coastal territories of the Bay of Taganrog and the Sea of Azov to identify indicators for assessing natural risks. The object of research is a complex system of the coastal zone, consisting of subsystems of land, sea and coast. The subject of the study is the assessment of the risk of loss of territory as a result of various natural factors, both constant over time (geological structure, height of the coastal cliff) and changing (dynamics of the level, waves, wind conditions). Within this framework, we show the use of a dynamic approach for zoning the shores of the Sea of Azov, performed based on a comprehensive analysis of natural and anthropogenic factors that determine the development of dangerous coastal processes (DCP). All factors divided into two groups: those that increase the intensity of coastal processes and those that contribute to reducing their manifestations. It established that hydrodynamic factors in the development of DCP are the determining factors. Anthropogenic impact can be associated with both global and regional impacts, through ecosystem changes, regulation of river flow, environmental pollution, and local – irrational coastal protection, industrial and agricultural activities in the coastal zone, unauthorized removal of beach material, etc.

Authors:   Federal Research Center Southern Scientific Center, of Russian Academy of Sciences, Rostov-on-Don, Russia, Patrakeeva O.Yu.
Published: October 2020

Infrastructure provides stimulus to the national and region economy. This paper develops theoretical and practical framework for estimating the economic effects generated from infrastructure. Its three types are considered: roadway, railway, and telecommunications. The hypothesis is that the infrastructure has a positive impact on regional economic development and there are spatial external effects. Estimation showed that road and telecommunications have a positive impact on economic development for Russia, and their external effects also appear. The contribution of railways to increasing labor productivity was insignificant for western and eastern regions. At the same time, the mobile communications per capita is a significant factor for western and eastern regions. The results indicate the necessity to adjust the strategy aimed at implementation of large-scale interregional infrastructure projects.

Managing Stakeholder Conflicting Expectations in Higher Education: a Hybrid Approach
Authors: Al-Sharafi Abdul Gabbar , Al-Rubai’ey Fatema
Published: October 2020

This paper proposes a hybrid approach to the management of stakeholder conflicting expectations in higher education (HE) by combining Stakeholder Theory (ST) and a participatory approach. In this paper, we use an ex post facto approach to retrospectively report Sultan Qaboos University (SQU) experience in managing stakeholder conflicting expectations in developing the BA in English Language and Literature Program as a case study. We show that for an effective management of stakeholder conflicting expectations in HE, the three perspectives of ST (i.e., descriptive, instrumental and normative) have to be taken together as a unified approach with the normative perspective occupying the core. In addition, we argue that this unified approach should be complemented by a participatory approach to add an interactive dimension to stakeholder conflict management and allow stakeholders to become active conflict-solvers. The paper concludes that this hybrid approach is essential to manage stakeholder conflicting expectations in academic program development and to project academic program development in HE as a shared social responsibility.
Psychometric Properties of an Instrument Developed to Assess Students’ Evaluation of Teaching in Higher Education
Authors: Akour Mutasem M. , Hammad Bashar K.
Published: October 2020

Student evaluation of teaching is a global predominant practice in higher education institutions. Therefore, a major university in Jordan developed a questionnaire for students’ use in evaluating their instructors’ teaching effectiveness.  Since student evaluation of teaching is an important process, the present study tried to examine the psychometric properties of the instrument. Item-total correlations showed acceptable internal consistency. In addition, a two-factor structure of the scale (teaching effectiveness and course attributes) was supported by exploratory factor analysis and confirmatory factor analysis from two independent samples. Convergent validity was supported by a moderate correlation coefficient between course averages of students’ ratings on the first factor and course averages of students’ final grades in each course. Finally, students’ responses on the factor that captures teaching effectiveness were found to have very high internal consistency (Cronbach’s alpha of 0.96). However, this instrument lacks evidences of content validity and convergent validity. Therefore, it is important to be cautious in evaluating faculty members and making promotion decisions that is based solely on the scores obtained using this instrument.
Intelligent data analysis of the influence of COVID-19 on the stock market using Case Based Reasoning

Published: October 2020

Starting with the differences between forecasting and prediction and going deeper into prediction, a knowledge-based model is presented. The evolution of the stocks markets are analyzed, as well as how the epidemics and pandemics prior to the stock markets have affected them and how it is currently being affected by covid-19. The defined model is applied to a use case using Case-Based Reasoning (CBR): it makes an analogy between the 2008 crisis with the covid-19 crisis in 2020 to predict whether the stock markets will take more or less time to recover.
Sketching enactive interactions
Authors: Rodriguez Andres
Published: October 2020

The continuous development of interactive technologies and the greater understanding of body importance in cognitive processes has driven HCI research, specifically on interaction design, to solve the user’s relationship with a multitude of beyond desktop devices. This has opened new challenges for having processes, methods and tools to achieve appropriate user experiences. Insofar as new devices and systems involve the body and social aspects of the human being, the consideration of paradigms, theories and support models that exceed the selection of navigation nodes and the appropriate visual organization of widgets and screens becomes more relevant. The interaction design must take care not only to get the product built properly but also to build the right product. This thesis is at the crossroads of three themes: the design of interactive systems that combine a foot in the digital and one in the physical, the theories of embodied and enactive cognition and the creative practices supported by sketching, in particular the processes of generation, evaluation and communication of interaction design ideas. This work includes contributions of different character. An in-depth study of the theories on embodied and enactive cognition, the design of interaction with digital devices and sketching as a basic tool of creative design is carried out. Based on this analysis of the existing literature and with a characterization of the enactive practice of enactive interactions based on ethnomethodological studies, a framework is proposed to conceptually organize this practice and a support tool for that activity conceived as a creative composition. The contributions are discussed, and possible lines of future work are considered.

O objetivo deste artigo é apresentar o processo de uma experiência pedagógica ambiental desenvolvida na Escola de Educação Básica Professor Olavo Cecco Rigon, localizada na microbacia hidrográfica do Rio Lajeado Sabão, no Município de Concórdia-SC. No ano de 2016 iniciou-se o Projeto denominado “Conhecer e interagir com e na bacia hidrográfica da Escola”, financiado pela Agência Nacional de Águas e Coordenação de Aperfeiçoamento de Pessoal de Ensino Superior. A metodologia adotada engloba a pesquisa-ação, aplicada exploratória, bibliográfica, de campo e qualitativa. O estudo ocorreu com duas turmas de terceiros anos do ensino médio. Dentre os resultados obtidos estão o desenvolvimento de trabalhos pedagógicos sobre o tema gerador água, sobre a implementação de práticas ou tecnologias sociais de gestão, governança e preservação das águas e sobre a produção de materiais didáticos pedagógicos. A partir da temática, a pesquisa desenvolveu a educação ambiental de forma interdisciplinar e continuada com os estudantes, voluntários, população do entorno da microbacia, além de implementar projetos de intervenções nos espaços mencionados.

Sobre la identidad de Scrophularia schousboei Lange
Authors: Ortega Olivencia Ana , Devesa Juan Antonio
Published: October 2020

El estudio morfológico comparado de Scrophularia schousboei Lange y S. su- blyrata Brot. ha puesto de manifiesto que la variabilidad morfológica indicada para S. schousboei corresponde en realidad a la observable en plantas jóvenes o de primer año de S. sublyrata, por lo que se deduce que ambos nombres han sido aplicados a plantas de la misma especie pero de distinta edad, debiéndose denominar el taxon como S. syblyrata Brot., por ser este el epíteto disponible más antiguo.
