Aims

Currently, there are few available data regarding a possible role for subclinical atherosclerosis as a risk factor for mortality in Coronavirus Disease 19 (COVID-19) patients. We used coronary artery calcium (CAC) score derived from chest computed tomography (CT) scan to assess the in-hospital prognostic role of CAC in patients affected by COVID-19 pneumonia.

Methods

Electronic medical records of patients with confirmed diagnosis of COVID-19 were retrospectively reviewed. Patients with known coronary artery disease (CAD) were excluded. A CAC score was calculated for each patient and was used to categorize them into one of four groups: 0, 1–299, 300–999 and at least 1000. The primary endpoint was in-hospital mortality for any cause.

Results

The final population consisted of 282 patients. Fifty-seven patients (20%) died over a follow-up time of 40 days. The presence of CAC was detected in 144 patients (51%). Higher CAC score values were observed in nonsurvivors [median: 87, interquartile range (IQR): 0.0–836] compared with survivors (median: 0, IQR: 0.0–136). The mortality rate in patients with a CAC score of at least 1000 was significantly higher than in patients without coronary calcifications (50 vs. 11%) and CAC score 1–299 (50 vs. 23%), P < 0.05. After adjusting for clinical variables, the presence of any CAC categories was not an independent predictor of mortality; however, a trend for increased risk of mortality was observed in patients with CAC of at least 1000.

Conclusion

The correlation between CAC score and COVID-19 is fascinating and under-explored. However, in multivariable analysis, the CAC score did not show an additional value over more robust clinical variables in predicting in-hospital mortality. Only patients with the highest atherosclerotic burden (CAC ≥1000) could represent a high-risk population, similarly to patients with known CAD.

Published: July 2021

Alzheimer’s Disease (AD) is the most prevalent type of dementia and has a high prevalence in the aging population. Due to the requirements for care, it is valuable for members of the healthcare system to be knowledgeable about AD and its treatment. Community pharmacists are particularly valuable in assisting in AD care because of their accessibility to the general public and they are a source for dispensing AD medications. The purpose of this study is to assess the level of knowledge of AD among Ohio community pharmacists based on regional practice settings using the Alzheimer’s Disease Knowledge Scale (ADKS). A standardized, 30-question assessment tool known as the Alzheimer’s Disease Knowledge Scale exists to measure the level of knowledge of AD among a given population. Studies on AD knowledge have been conducted using this tool, and the use of this scale identifies major misconceptions about AD that could be addressed in education initiatives for both the general public and for health care professionals. This study implemented this tool to compare the knowledge of community pharmacists that serve rural areas to those that serve urban areas. The Ohio Board of Pharmacy provided a list of emails of community pharmacists to send an anonymous survey including both demographic questions and the ADKS. Statistical analyses including independent t-tests and descriptive statistics were conducted using SPSS to determine the significance of the data. This study found no statistically significant difference between urban versus rural community pharmacists. However, in the future we hope to identify specific questions that correlate to areas of AD where continuing education may be helpful in improving patient outcomes by enabling caregivers and healthcare providers with a more accurate understanding of AD.

Published: July 2021

The patient was a 33-year-old man with a history of recurrent pneumonia, autism, bipolar disorder, hypothyroidism, intermittent asthma, and nonischemic cardiomyopathy attributed to cocaine use who was admitted with hypoxemic respiratory distress with bilateral infiltrates seen on a
chest radiograph. He was treated for community-acquired pneumonia but progressed to respiratory failure that required intubation and broad-spectrum antibiotic therapy. His medical history was notable for short stature, abnormal facial features, and, since childhood, at least two pneumonias
per year that required antibiotics. The initial evaluation for an underlying primary immunodeficiency found that the patient had normal quantitative immunoglobulin levels, with absent CD19+ B cells. This case highlighted the evaluation of the humoral immune system for hospitalized
adult patients with recurrent infections as well as the use of genetic testing to diagnose rare immunodeficiency syndromes.
Aproximación a los conceptos de justicia rogada y de justicia material
Authors: Cortés Soto Jorge Alirio , Ospina Montoya Edgar
Published: July 2021

El presente documento estudia la dicotomía que representa para el juez la justicia rogada o formal y la justicia material, a la hora de dispensar justicia a los asociados y tomar la decisión respectiva, pues de un lado, debe resolver el caso en aplicación de la ley (adecuando o subsumiendo los aspectos que le presenten las partes en las normas) y por el otro, recurrir a los valores y principios que consagra la normatividad (ponderando los derechos en conflicto), dado que el artículo 230 de la Carta prevé que los jueces en sus decisiones solo están sometidos al imperio de la ley, siendo la equidad, los principios generales del derecho y la doctrina, criterios auxiliares.   Para el efecto se realiza un análisis histórico, racional y descriptivo del proceso filosófico que enfrentan al derecho positivo con el derecho natural, el derecho con la moral, la justicia y el derecho, para identificar cómo se ha llegado al conflicto que ofrecen dichos principios y concluir con la identificación de los fundamentos que ellos tienen; aspecto de crucial importancia para que los jueces tomen sus decisiones.
El juez constitucional e interpretación de normas en Japón
Authors: Ueno Mamiko
Published: July 2021

El presente artículo desarrolla, de forma expositiva y analítica, la composición del sistema judicial japonés a partir del análisis de la Constitución Política de 1946. Se centra en las atribuciones otorgadas por la Carta Política a los jueces en Japón, así como en la interpretación de la norma y en el papel muy conservador y “negativista” de la Corte Suprema de Justicia como alto tribunal encargado de decretar la constitucionalidad o inconstitucionalidad de cualquier ley, decreto, reglamento o acto oficial. La tendencia reiterada ha sido la de “esquivar” la cuestión de constitucionalidad y de hacer prevalecer el poder discrecional del legislador.
Desarrollo legal y jurisprudencia constitucional en Colombia sobre la protección del medio ambiente y los recursos hídricos
Authors: Dussán Bastidas Héctor Javier , Martínez Andrade Juan Pablo
Published: July 2021

En las últimas décadas, como consecuencia del cambio climático y las altas temperaturas presentadas durante el “Fenómeno del Niño”, se ha acentuado en Colombia y el Departamento del Huila la escasez de agua en los acueductos municipales. Esta problemática que genera preocupación en las autoridades y en la población en general, ha despertado el interés en la academia a debatir si las diferentes disposiciones legales existentes la legislación colombiana son suficientes para hacer frente a la crisis ambiental y especialmente a la pérdida de recursos hídricos superficiales, lo cual afecta el acceso al líquido para el consumo humano.

 

En ese orden, a partir de la identificación y análisis del desarrollo legal y jurisprudencial de la Corte Constitucional de Colombia, relacionados con la protección ambiental y en especial al tema del agua, se advierte que desde el siglo XX a raíz de innumerables problemas suscitados por la actividad económica con impacto negativo en la salud humana, se dieron las primeras normas de contenido medioambiental, disponiendo algunas medidas sobre el uso del agua utilizada para el consumo humano, pasando por el Decreto Ley 2811 de 1974, el cual adoptó el Código Nacional de Recursos Naturales Renovables y de Protección al Medio Ambiente, y un profuso desarrollo normativo ambiental, hasta llegar a la Constitución Política de 1991 considerada como una “Constitución Ecológica”. Desde ese momento, se ha intensificado la producción normativa y jurisprudencial en torno a la protección jurídica del agua como generadora de vida.

Authors:   Department of Educational Sciences and Early Childhood Education, University of Patras, Patras, Greece, Poulou Maria S.
Published: July 2021

Research evidence on Social and Emotional Learning implementation at schools has long been recognized. Most of the research however, has been focused on cultivating explicit social and emotional skills and relatively scant attention has been given to those positive human qualities or virtues such as kindness. Current study aims to illuminate pre-service early childhood teachers’ conceptualization of kindness. Two hundred and nineteen pre-service students described their perceptions of kindness. Kindness was conceptualized as a range of acts and words indicating respect, understanding and emotional support, which promote personal development and healthy relationships. Teachers’ kindness specifically was perceived important in cultivating students’ personality and teacher-student relationships. The findings of the study contribute to the topic of kindness in education which is a promising but undervalued area of school-based programming.

Relations between the ancient Turks and the Yenisei Kyrgyz at the turn of the early Middle Ages (ancient Turks at the turn of the early Middle Ages)
Authors: Khudyakov Yu. S. , Borisenko A. Yu.
Published: July 2021

It is represented in an article the history of the Turks till the second half of the 1st millennium A.D., from migration period out of Central Asian steppes to boundaries of the Chinese empire and their resettlement to the Altai Mountains, when the Old Turkic state was at its greatest height, took control the number of sedentary agriculturist oases and successfully confronted the major powers of that time - Chinese Persian and Byzantine empires. Throughout the vast territory of the Sayan and Altai Mountains and Central Asian region there are represented all major types of funerary and memorial constructions of the Old Turks, which constitutes burial places according to the ritual of inhumation accompanied by riding horses or rams and memorial complexes in the form of vertically dug stone plates fences with vertically fixed stone steles. Authors of the article consider designated historical period of the Old Turkic history from the perspective of interaction of the Old Turks and Kyrgyz, who resided in the territory of Minusinsk Hollow. Mutual relations between those two peoples took various forms in different times: unabashedly hostile passively feudatory, when the Yenisei Kyrgyz preferred not to show pure resistance to the Turks. However, such instability of their own position has not disturbed the Kyrgyz to expand the range of their own vassals.

Authors: Ekwunife Christopher Nonso , Okonta Kelechi E. , Enendu Stephen E.
Published: July 2021

Objectives:

Percutaneous endoscopic gastrostomy (PEG) is a well-established endoscopic procedure that is used predominantly to create enteral access for feeding. Its use has not been widespread in Nigeria despite its efficacy. This study is done to review the early experiences in the use of PEG in Federal Medical Centre, Owerri and Carez Clinic, Owerri.

Material and Methods:

This is a 4-year retrospective cross-sectional study of patients who had PEG from January 2015 to December 2018. The indications, complications, and outcomes of the procedure were analyzed.

Results:

A total of 13 patients had pull-type gastrostomy during this period. Six (46.1%) patients had the procedure on account of neurologic disorders, 4 (30.8%) patients had esophageal tumors, while 3 (23.1%) patients had esophageal motility disorders. The overall success rate for PEG tube placement was 100%. The most common complication was superficial skin infection 30.8% (4/13). No mortality was attributable to the procedure.

Conclusion:

PEG is still not commonly done in our setting, but it is a relatively safe procedure. Physicians should be encouraged to offer it to our teeming patients with neurologic disorders who may benefit from it.
The expected indications for video-assisted thoracoscopic surgery in Sub-Saharan Africa
Authors: Okonta Kelechi E.
Published: July 2021

Video-assisted thoracoscopic surgery (VATS) in Sub-Saharan Africa (SSA) is still an evolving surgical procedure that can be used for well-selected patients to treat various pathologies such as pleural disease, lung pathology, esophageal disease, diaphragmatic pathology, mediastinal disease, and other conditions. From the review of literature, over the years, for which VATS has been in use showed that SSA with a good sizeable population has still not embraced the surgical procedure. This is so despite the wide spectrum of diseases and clinical conditions in the region for which VATS can conveniently be applied in other to improve post-operative outcome and reduce post-operate mortality rate. Thus, this review should be a wakeup call for the region and to stimulate the desire in them to make consistent efforts by training doctors and putting the necessary infrastructures in place to ensure the adoption of this method of medical and surgical practice as it decreases post-operative complications and post-operative mortality rates.
Retrospective Study of Blood Transfusion Complications in the Capital Region of Denmark from 1999-2017: Characteristics of Potentially “Dangerous” Blood Donors?s

Published: July 2021

Objectives: We hypothesized that the blood donors most frequently involved in complications would induce more and severe immunologic transfusion complications compared to other donors, i.e. potentially “dangerous”. Secondary aims were differences in demographic variables. Background: Donor-related mechanisms may contribute to allogeneic blood transfusion complications and may represent a dangerous treatment adverse event. Materials and Methods: By analyzing transfusion data from the Capital Region of Denmark from January 1, 1999 to December 31, 2017; 2,574,646 blood transfusions and 9,779 transfusion complications from 194,432 blood donors were included in our dataset. We divided donors into three groups based on the number of complications and complication frequency (potentially “dangerous” vs. two differently defined control groups i.e. control 1 and control 2), and compared the nature of transfusion complications and demographic variables by statistical analysis. Results: There were no differences in the proportion of complication types between the potentially “dangerous” donors and control donors, and no difference in the proportion of complications from RBCs, plasma or platelets according to ABO and RhD blood types. However, more potentially “dangerous” donors were female and had ABO blood type B compared to control donors (p<0.001 and p<0.01, respectively). The potentially “dangerous” donors were younger compared to control donors (40.36 years vs. 45.24 years and 42.84 years, p<0.001). Conclusion: The potentially “dangerous” did not display more/severe immunologic transfusion complications compared to control donors. However, they differed in regards to gender, age and blood type. Further research regarding the differences in complication frequency per donor and demographic variety is warranted.
Qubit-based unclonable encryption with key recycling
Authors: Leermakers Daan , Skoric Boris
Published: July 2021

We re-visit Unclonable Encryption as introduced by Gottesman in~2003 \cite{uncl}. We look at the combination of Unclonable Encryption and Key Recycling, while aiming for low communication complexity and high rate. We introduce a qubit-based prepare-and-measure Unclonable Encryption scheme with re-usable keys. Our scheme consists of a single transmission by Alice and a single classical feedback from Bob. The transmission from Alice to Bob consists entirely of qubits. The rate, defined as the message length divided by the number of qubits, is higher than what can be achieved using Gottesman's scheme~\cite{uncl}. We provide a security proof based on the diamond norm distance, taking noise into account.
Quantum digital signatures with smaller public keys
Authors: Skoric Boris
Published: July 2021

We introduce a variant of quantum signatures in which nonbinary symbols are signed instead of bits. The public keys are fingerprinting states, just as in the scheme of Gottesman and Chuang \cite{GC2001}, but we allow for multiple ways to reveal the private key partially. The effect of this modification is a reduction of the number of qubits expended per message bit. Asymptotically the expenditure becomes as low as one qubit per message bit. We give a security proof, and we present numerical results that show how the improvement in public key size depends on the message length.
Dissipative encoding of quantum information
Authors: Baggio Giacomo , Ticozzi Francesco , Johnson Peter D. , Viola Lorenza
Published: July 2021

We formalize the problem of dissipative quantum encoding, and explore the advantages of using Markovian evolution to prepare a quantum code in the desired logical space, with emphasis on discrete-time dynamics and the possibility of exact finite-time convergence. In particular, we investigate robustness of the encoding dynamics and their ability to tolerate initialization errors, thanks to the existence of non-trivial basins of attraction. As a key application, we show that for stabilizer quantum codes on qubits, a finite-time dissipative encoder may always be constructed, by using at most a number of quantum maps determined by the number of stabilizer generators. We find that even in situations where the target code lacks gauge degrees of freedom in its subsystem form, dissipative encoders afford nontrivial robustness against initialization errors, thus overcoming a limitation of purely unitary encoding procedures. Our general results are illustrated in a number of relevant examples, including Kitaev's toric code.
Short paths in PU(2)
Authors: Stier Zachary
Published: July 2021

Parzanchevski--Sarnak \cite{PS} recently adapted an algorithm of Ross--Selinger \cite{RS16} for factorization of $\PU(2)$-diagonal elements to within distance $\eps$ into an efficient probabilistic algorithm for any $\PU(2)$-element, using at most $3\log_p(\nicefrac{1}{\eps^3})$ factors from certain well-chosen sets. The Clifford+$T$ gates are one such set arising from $p=2$. In that setting, we leverage recent work of Carvalho Pinto--Petit \cite{CPP} to improve this to $\frac{7}{3}\log_2(\nicefrac{1}{\eps^3})$, and implement the algorithm in Haskell.

Published: July 2021

The unique characteristics of natural honey obtained in any source in topical chronic nonhealing ulcers have been decreased discomfort, oedema, inflammation, deodorization, disinfect, neo-vascularization, collagen synthesis, granulation, epithelization and hence the ulcer treatment method. In that study, 200 patients were treated in a forward-looking, unrandomized experiment, with persistent, unhealing ulcers found in various areas of their body in the two groups keeping 100 in Group A and used honey dressing and Group B managed without using honey. Natural honey from multiple sources has been used. The main explanation for reduced mobility and loss of work illustrates productivity being pain and fever. The leading causes of healing delays were bacterial infection, necrotic tissue involvement, bedridden state, age, fatigue, Ulcer located near the joint. The quality, the simplicity of application and the efficiency make the control of recurrent nonhealing Ulcers easier for natural honey. For low cost, easy access, and improved healing make it a valuable option for natural honey to handle chronic, nonhealing ulcers, as well as healthy use in diabetic patients.
Pottery of the Nabil Archaeological Culture from Sakhalin Island
Authors:   Small innovative enterprise of Sakhalin State University, Pashentsev P. A. ,   OOO “Iziskatel SakhGU”
Published: July 2021

The article considers the results of multidisciplinary analysis of the Nabil archaeological culture pottery identified in 2005 by results of the archaeological researches in North Sakhalin. The Nabil archaeological culture includes the ceramics complex consisted of pointed shape pottery decorated by comb stamps. The sources of the study are the archaeological studies of the settlements (the collections and reports) organized by the research team of Sakhalin Archaeological and Ethnography Laboratory of IAET SB RAS and SakhGU in 2004–2015 and additional archaeological material from other collections. According to absolute dating of the Nabil archaeological complexes, the material was clustered into three chronological periods: early – 3065–2781 cal BP, middle – 2754–2342 cal BP, late – 2334–2009 cal BP. The study used technical methods like X-ray Diffraction analysis, Petrographic analysis of pottery, Optical Binocular Microscopy, method of sherds’ laboratory re-firing, statistic-and-classification method. Most part of the pottery was identified as the remains of the everyday utensils, the lowest rate of the others were used like celebratory vessels. Recipes of the moulding compounds are almost homogeneous. Their raw material includes meagre clay with a lot of dust-like natural sand. As a thinning agent for the moulding composition added sand temper in pottery paste and sometimes chamotte. The vessels were made by the wall only “seedbody”. The walls of the vessels formed by the linear-ring building method. The pottery was roasted with bonfire firing, the later period with oven devices for pottery firing. The vessel's shapes are asymmetry. The contour of the vessel shape of the Nabil’s type is oval-shaped with either concave or straight or ill-defined neck. The upper part of the vessel surface was decorated. The basic type of ornamentation is the comb stamps. The elements of the pottery ornamentation are both continuous and discrete horizontal lines, curved ornament, short, long, diagonal, and vertical lines as well as individual impressions. The pattern of the pottery decoration consists of either horizontal continuous lines or discrete ones with either series diagonal or vertical short stamping. It is widespread. Stylistically the composition of the pottery decoration evokes associations with the row of the beads and pendants. In conjunction with nipple-shaped thickened of the vessel to the bottom it creates a stylistic image of the female breast. There was the infiltration of foreign cultural elements in the Nabil archaeological culture in the late period.

TaBAT: Design and Experimentation of a Learning Analysis Dashboard for Teachers and Learners
Authors: Safsouf Yassine , Mansouri Khalifa , Poirier Franck
Published: July 2021

Aim/Purpose: Since the beginning of the COVID-19 pandemic, many countries have adopted online education as an alternative to face-to-face courses. This has increased awareness of the importance of analyzing learning data left by students to improve and evaluate the learning process. This article presents a new tool, named TaBAT, created to work with different LMSs in the form of dashboards accessible online and allowing teachers to monitor the progress of their learners and at the same time allow learners to visualize their learning process.

Background: TaBAT is designed based on the results of our previous research on factors that can influence the success of online learners, where we proposed and statistically validated a model for assessing the success of online learners called e-LSAM (e-Learner Success Assessment Model).

Methodology: Two studies are presented in this article. The first one is conducted on a group of students from two classes (each composed of two groups) of a higher institute in Morocco, who participated in courses organized in blended learning on the Moodle platform. For each class, one of the two groups had access to the experiment to use the TaBAT tool (exposed group) to analyze the learning traces, while the second group did not have access to the dashboard (control group). The second study aimed to understand the impact of the usage of the TaBAT tool on the two exposed groups.

Contribution: The purpose of this article is to present a new analysis tool as well as to test this tool and to evaluate its impact on self-regulation and the prediction of academic success and, finally, to see how these students evaluate this tool.

Findings: The results of the TaBAT usage demonstrate the effectiveness of the success algorithm, based on our theoretical model e-LSAM. The results also prove that this tool was able to increase the performance of the students of both groups exposed. The general evaluations of the participants also confirmed these results.

Impact on Society: The article proposes a tool for institutions to facilitate the monitoring and control of students’ learning process. The tool provides visual information for teachers to study and react to in the educational context and gives students visualizations to promote their self-reflection and increase their performance and academic success.

Future Research: Generalize the use of the TaBAT tool, incorporating both private and public institutions, in order to confirm the results obtained in this article and at the same time improve the self-regulation and academic success of learners.
Case presentation of Safe and Effective Use of Medical Cannabis in the Elderly
Authors: Barton Luisa , Nisan Clara , Burleigh Carey , Fredericks Suzanne
Published: July 2021

Introduction: The therapeutic benefits of medical cannabis have been demonstrated for a number of chronic conditions impacting the elderly population, such as pain management, and as alternatives to antipsychotic and opioid interventions, as well as end of life treatments. However, this therapeutic intervention has not become part of routine care for seniors living in long-term care facilities because of reduced public acceptance and stigma. The aim of this paper was to present case studies outlining the effective use of medical cannabis to treat elderly patients with a variety of medical conditions and symptoms such as: post traumatic stress disorder, pain, anxiety, delusions, as well as palliative care. Cannabis was also used to taper antipsychotic medications, and for managing those in palliative care.  

Case Presentation: Three cases highlighting the use of medical cannabis are described, from the perspective of a nurse practitioner-led interdisciplinary team approach.

Management and Outcome: Using a variety of combinations of medical cannabis (cannabidiol and delta-9-tetrahydrocannabinol) in oral formulations, the long-term care facility has achieved a dramatic reduction in the use of antipsychotic medications. Medical cannabis has shown alleviation of many symptoms such as: pain, dyspnea, agitation, fatigue, weakness, loss of appetite, nausea, vomiting, and twitching. Positive results were noted in several palliative care patients who received medical cannabis for pain and symptom management.

Conclusion: As an adjunct therapy for managing post traumatic stress disorder and other conditions, medical cannabis has been effective in reducing symptoms and for improving the patients’ overall quality of life. Continued evaluation into the long effectiveness of medical cannabis provided to individuals over the age of 65 years is suggested. This nurse practitioner-led therapeutic intervention highlights the potential health benefits of medical cannabis and has clinical implications for practice and education.

Background: Numerous studies have shown an effect of rapidly spreading SARS-COV-2 on combined anxiety-depressive disorders and maladjustment syndrome occurrences. Objective: To determine the primary medical students’ reactive anxiety level and the final scores of their educational progress in distance learning during the SARS-COV-2 pandemic. Materials and Methods: The study involved 824 students at medical universities in Saratov and Moscow. The assessment of the reactive anxiety level was carried out according to the State-Trait Anxiety Inventory, STAI; the average score of students' academic performance was calculated according to the data of the technological platform "1C: Enterprise" version 8.4.1. The survey was completed during distance learning in May 2020. The quality of distance learning was compared to a similar score for 2019, when students were trained in a traditional way. Statistical analysis was conducted using Statistica 6.0. Results: It was shown the presence of moderately severe disorders among the primary medical students according to the average score of reactive anxiety (43.28 ± 12.85), that expressed more in females s (p<0.05), After distance learning, lasting 25% of the whole course, the overall performance score in theoretical knowledge did not change significantly (p>0.05) but the practical skills suffered much especially in time trend (p<0.05). Novelty: It was found that a high level of the reactive anxiety negatively affects the students' adaptive capabilities and the education quality. The specificity of programs at different faculties can determine the state of the students' psychological status. Findings:Timely transition to online classes during pandemics helps to preserve the students' mental well-being and the quality of the educational process. The duration of distance learning for a practical course should not exceed 25% of the whole course. Doi: 10.28991/esj-2021-SPER-07 Full Text: PDF

Authors: Silva Willia, , Brant Rogério , Sampaio Andressa
Published: July 2021

Objetivou-se analisar as implicações dos aspectos inerentes à modernidade e quais os impactos gerados para as classes trabalhadoras. O estudo necessitou de um aprofundamento teórico e bibliográfico, visando um maior entendimento das questões ligadas a esses impactos e de que forma as classes trabalhadoras seguem expostas a trabalhos precários, terceirização dos trabalhos, desemprego, subemprego e trabalho informal. Os impactos desta modernidade para as classes trabalhadores e para as relações de trabalho impostas pelo capital, só aumentam as discussões sobre as questões precárias de trabalho, ou seja, sobre as formas (modernas ou não) de dominação de uma classe articulada e poderosa, sobre outra, frágil e totalmente desarticulada. Para tanto, os procedimentos metodológicos utilizados são: pesquisa bibliográfica, documental com abordagem qualitativa e análise de conteúdo
Enhanced Oil Recovery and CO2 Storage Potential Outside North America: An Economic Assessment
Authors: Ward Colin , Heidug Wolfgang
Published: July 2021

Storing carbon dioxide (CO2 ) in oil reservoirs as part of CO2 -based enhanced oil recovery (CO2 -EOR) can be a cost-effective solution to reduce emissions into the atmosphere. In this paper, we analyze the economics of this option in order to estimate the amount of CO2 that could be profitably stored in different regions of the world. We consider situations in which the CO2 -EOR operator either purchases the CO2 supplied or is paid for its storage. Building upon extensive data sets concerning the characteristics and location of oil reservoirs and emission sources, the paper focuses on opportunities outside North America. Using net present value (NPV) as an indicator for profitability, we conduct a break-even analysis to relate CO2 supply prices (positive or negative) to economically viable storage potential.

This study sought to determine the computing disciplines’ graduate attributes that are perceived as most important by academics of Nigerian Higher Education Institutes (HEIs) to make graduates in computer related disciplines desirable to potential employers and entrepreneurship in Nigeria. The descriptive survey research design was adopted. One hundred and Fifty (150) academic staff of computer related disciplines across the HEIs (Universities, Polytechnics and Colleges of Education) in the North-Western Nigeria were screened and used through convenience random and purposive sampling methods. The Computing Disciplines’ Graduate Attributes Scale (CDGAS) (r = 0.90) was the research instrument used in gleaning the field data. Three research questions were raised and one hypothesis formulated, tested and analyzed using Pearson Product Moment Correlation (PPMC). The findings revealed that effective communication skills, leadership quality, collaboration and teamwork, lifelong learning skills, cognitive ability and practical skills, ability to apply knowledge to solving theoretical and practical problems creativity and innovative thinking are the most important computing discipline’ graduate attributes that are desirable for graduate employability and entrepreneurship in Nigeria. Also, result from hypothesis testing showed no significant relationship between computing discipline graduate attributes desirable for employability and that of entrepreneurship in Nigeria (r = 0.622; P < 0.05). Conclusively, the study recommended that career development support efforts should be included in the curriculum, which will focus on helping prospective graduate in computing related discipline on how graduate attributes can hinder or increase their employability and entrepreneurship strengths.
The same old story: Workplace violence towards healthcare providers during COVID-19 pandemic
Authors: Ali Kemal Erenler  , Seval Komut  , Ahmet Baydin
Published: July 2021

Workplace violence (WPV) is a growing public health problem worldwide affecting physical and mental health of healthcare providers. It has many deterious consequences such as anxiety, burnout and intention to leave the job. With the pandemic, it is assumed that the incidence of workplace violence tends to increase. Particularly, misinformation about the nature of the disease create prejudice against staff working in healthcare facilities. There are several measures to be taken for prevention of physical and mental health of healthcare providers. A “zero-tolerance policy against violence” should be implemented. Doctors and nurses should be encouraged to report incidents. Social support should be provided for the personnel. In this review, our aim was to clarify if there is an increase in the incidence of WPV against healthcare providers in the pandemic process. We also aimed to make recommendations about measures that must be taken to prevent healthcare providers from detrimental effects of WPV.

Among Rosaceae family's most popular and important plants Rosa x damascena Herrm. holds one of the top places due to its centuries-long application in perfumery, cosmetics, aromatherapy and medicine. Despite this, the chemical and pharmacological study of different products obtained from R. damascena still does not lose its relevance. Currently, considerable attention is paid to the valorization of the waste from rose oil production in order to fully utilize valuable physiologically active constituents. The present study provides data on some pharmacological properties of the aqueous extract of rose oil waste from the R. damascena cultivated in Georgia. In particular, evaluation of gastro- and hepatoprotective activity of the aforesaid extract has been carried out in animal models and revealed its efficacy. The extract appeared to dose dependently stimulate leucopoiesis (up to 75%) and prevent ethanol-induced gastric injury (20-80%). As well, the extract ameliorated hepatoxic effects of carbon tetrachloride by 63%.

Published: July 2021

Introduction: Diabetes disease is a group of metabolic diseases in which a person has high blood sugar, either because the pancreas does not produce enough insulin, or because cells do not respond to the insulin that is produced. Designing an automated system for regulating blood glucose in patients with diabetes is a solution that researchers have been paying close attention to in recent years. Therefore, safety is the minimum requirement for safety-critical systems such as the artificial pancreas. The present study introduces a safe, robust, performance-guaranteed optimal controller that can safely regulate blood glucose in the disturbance.Material and Methods: In this section, first, regulate blood glucose levels in simulation studies is evaluated. For this purpose, a dynamic model is used. The model includes a virtual patient, an insulin pump, and a continuous blood glucose level sensor. The virtual patient model represents the dynamics of insulin-glucose, carbohydrate-glucose, and exercise-glucose.Results: The need to not reset the controller parameters for patients in each category is one of the suggested controller's benefits. However, the PID controller needs to reset the parameters for each group of patients, the predictive control method requires the estimated model of the patient, and its performance is different on different days because the insulin-glucose dynamics for an individual changes day by day.Conclusion: Taking into account different sensitivities of body tissue to insulin, the results of evaluating the controller for two different groups of patients have shown that the controller is resistant to day-to-day changes in patients who may experience changes in insulin sensitivity, even with stress or medication and will not lose its optimal function. Based on the simulation results, the proposed controller can reduce the external disturbances' effect, whose amplitude is to a good extent within the body's physiological range.
