A computer three-dimensional (3D) hydrothermodynamic model was designed for refined description of intra-annual temperature stratification in deep freezing Lake Teletskoye. The work is aimed at testing this model through simulation of a complex hydrophysical phenomenon, i.e. spring thermobar for real conditions of Lake Teletskoye. In June 2018, while performing field observations of temperature stratification in Lake Teletskoye, a thermobar (stretching from the mouth of the Chulyshman River at the lake’s southern tail up to its deep-water part) was detected and studied. Using the constructed 3D model of thermal regime and actual input data for 2018, the estimate of spring-summer thermobar in the water body as well as the comparative analysis of numerical simulation results and field observation data were made.

Return levels of the major climatic stressors affecting the level of morbidity and mortality from cardiovascular diseases in the Leningrad region are evaluated. Based on data from 26 ob-serving stations located in 18 municipal units, a cluster analysis has been carried out allowing for classification of the territory according to the degree of influence of climatic conditions on the pathology of cardiovascular system. A projection of future changes in the selected climate indica-tors for the mid and end of the XXI century is conducted. The projection is based on the ensem-ble of climate change simulations using the Voeikov Main Geophysical Observatory regional cli-mate model under the IPCC RCP8.5 scenario. It has been shown that the main future threats due to the changing climate are associated with an increase in mortality from cardiovascular diseases connected with the projected increase in the intensity of the heat waves. The relevancy to take into account climate warming when it comes to developing a strategy for combating cardiovascu-lar diseases in municipal units is emphasized.

Published: June 2021

Carici-Genistetea lobelii Klein 1972 corresponds to cyrno-sardinian oromediterranean cushion scrub and related grasslands. In France, this class is only present in Corsica and the syntaxonomic scheme is debated among phytosociologists. The aim of this paper is to highlight the main plant associations of Carici-Genistetea lobelii Klein 1972 and to define the diagnostic species for each phytosociological unit. We compiled 519 vegetation plots and we applied EuropeanVegetationChecklist expert system for the classes of European vegetation to retain only vegetation plots belonging to Carici-Genistetea lobelii. We obtained a dataset with 189 vegetation plots and we classified them with Modified TWINSPAN classification. Our analyses recognized 6 plant associations and 3 sub-associations already described in the literature; and to describe a new alliance corresponding to the supra-mediterranean vegetations (Genistion salzmannii), a new association (Brimeuro fastigiatae-Juniperetum nanae) and its sub-association (alnetosum suaveolentis). For each of them, we identified diagnostic, constant and dominant species and produced their distribution map. Formal definitions were then written for each phytosociological unit (from subassociation to class) and grouped in an expert system to automatically classify the vegetations of Carici-Genistetea lobelii.
l' imaginaire haptique chez Georges Limbour
Authors: Khabou Saadia
Published: June 2021

Étant nourri par la philosophie phénoménologique, Georges Limbour est sensible aux Texturologies de Jean Dubuffet, qui non seulement font apparaître « la chair du monde » en faisant valoir la « chair de la peinture », mais aussi et paradoxalement deviennent le lieu par excellence où l’imagination matérielle, telle qu’elle est définie par Bachelard, trouve sa parfaite illustration. Ce qui fait que la contemplation d’une toile de Dubuffet déclenche chez Limbour une suite d’images fantasmagoriques, attestant de la puissance haptique de ces Texturologies et de leur aptitude à faire advenir l’absence à travers la forte présence de la matière picturale.

L’intérêt de cet article est de montrer comment le changement du paradigme pictural, qui marque le passage de la transparence iconique à l’opacité indicielle, permet paradoxalement d’ancrer plus concrètement le fait pictural dans l’expérience immanente du monde sensible et de créer par de-là même un imaginaire haptique qui fera la singularité de l’œuvre littéraire de Georges Limbour.
L' insécurité linguistique des femmes maghrébines immigrées en région parisienne
Authors: Ballarín Rosell María
Published: June 2021

L’insécurité linguistique ne concerne pas exclusivement les immigrés, mais ceux-ci sont souvent fortement touchés par ce sentiment du fait qu’ils ne maîtrisent pas la langue d’accueil et que leur langue maternelle a perdu sa valeur en tant qu’outil de communication dans la nouvelle société. Dans le présent article, nous analyserons comment ce sentiment s’articule dans le discours de 8 femmes d’origine maghrébine résidant à Paris ou dans ses alentours. Les réponses des enquêtées à nos questions nous donneront une idée du degré d’insécurité qu’elles sont conscientes de ressentir, puis une analyse plus formelle de leur discours nous permettra de repérer les manifestations les plus occultes de ce sentiment.

Authors: Alattar Feras N. Hasoon , Azeez Athar
Published: June 2021

The noticeable rise in electricity bills is one of the most major factors leading to an economic crisis for all parts of the world today. It causes many negative impacts on the economic lifestyle of society. This is due to the depletion of unnecessary energy which leads to financial losses for customers. Moreover, it leads to problems between customers and electric companies. Day by day, electricity bills increase further due to the increase in the number of electrical appliances, which in turn leads to an increase in the daily use of electricity. The absence of an energy consumption monitoring system exacerbates this problem. Therefore, it became necessary to develop a system to monitor energy consumption that can calculate daily consumption and display it to customers so that they can know their energy consumption without facing any difficulties. This paper aims to design and implement an energy meter system for optimized cost using internet of things (IOT) technology. This is to alert customers to take preventive measures that help limit the rise in electricity bills. The main components of system design are Node MCU, Arduino Uno (Atmega 328) Microcontroller, AC Fan, AC Light Bulb, LCD I2C (20x4) and ACS712 Current Sensor, which is responsible for sensing the current of electrical appliances. This system was simulated through the TINKERCAD program, as for the system programming, it was done through the Arduino Integrated Development Environment (IDE). Moreover, the system implementation and testing has been successfully completed, and the required results have been analyzed and successfully reached. The system has performed well and is acceptable, also it can be classified as efficient, simple and easy to use.
Expert system for identifying and analyzing the IoT devices using Augmented Reality Approach
Authors: ALKISHRI WASIN , Al-Bahri Mahmood
Published: June 2021

Biometrics In conjunction with the new development of the Internet of Things (IoT), augmented reality (AR) systems are evolving to visualize 3D virtual models of the real world into an intelligent and interactive virtual reality environment that facilitates physical identification of objects and defines their specifications efficiently. The integration between AR and IoT in a complementary way helps identify network-related items' specifications and interact with the Internet of Things more efficiently. An identity is a dedicated, publicly known attribute or set of names for an individual device. Typically, identifiers operate within a specific area or network, making it difficult to identify things globally. This paper explores the use of Augmented Reality (AR) Technology for identifying devices and displaying relevant information about the device to the user. Based on the developed model network, the developed system of identification of IoT devices was tested. Also, the traffic generated by the AR device when generating requests to the organization server was investigated. According to the test results, the system is undemanding to the main network indicators. The system-generated traffic is self-similar. The test results show that the server software can solve the problems of identifying IoT devices through interaction with augmented reality devices.

Challenges in speaking classrooms among non-English majors
Authors: Trinh Ngoc Boi , Pham Duy Thuy Thi
Published: June 2021

As a great challenge to most English learners, speaking skills have aroused the interest of numerous researchers in many countries where English is taught as a foreign language. This study aimed to investigate some difficulties that students faced in speaking classrooms. A group of 57 participants at Tra Vinh university was selected to complete the questionnaires to find out students’ speaking problems from psychological and linguistic perspectives and 12 of them participated in the face-to face interviews. The results from the questionnaire revealed that non-English majors encountered more linguistic difficulties than psychological ones. Also, students’ psychological problems identified includes: pressure to perform well, being overpowered by more competent students, fear of making mistakes in front of the class and fear of criticism or losing face. The linguistic difficulties are lacking vocabulary and topical knowledge, being uncapable of arranging ideas logically, insufficient sentence formation skills and inappropriate vocabulary. The findings from the interview also showed that learners encountered more linguistic difficulties. Based on the findings above, some possible solutions are suggested to assist students in improving their speaking skills when acquiring English.

Authors: Trinh Lan Thi , Nguyen Tu Cam Thi , Nguyen Anh Ngoc Thi
Published: June 2021

Sino-Vietnamese vocabulary is an important part of Vietnamese vocabulary. The ability to use Sino-Vietnamese vocabulary partially reflects one’s Vietnamese language competence; therefore, the ability to use Sino-Vietnamese vocabulary is an important element in the language ability of Vietnamese people in general, and secondary school students in particular. During in-class literature activities, secondary school students are equipped with Sino-Vietnamese vocabulary to a certain extent, but the effectiveness of using Sino-Vietnamese vocabulary in communication and in learning has yet to be fully evaluated. This article focuses on evaluating the ability to use Sino-Vietnamese vocabulary of secondary school students in Hanoi by using questionnaires and tests to obtain both subjective and objective data from the learner’s perspective. The survey results will be used as a practical premise to propose new teaching methods to develop Sino-Vietnamese language competence of secondary school students in Literature, in accordance with the 2018 General Education Curriculum.
Predictors of Psychosomatic Health during the first COVID-19 Outbreak in Greece. A Multiple Linear Regression Analysis in an Epidemiological Sample of 1,156 Individuals
Authors: Pilafas Georgios , Prouzou Alexandra , Strongylaki Nefeli Paraskevi
Published: June 2021

Background: Between March 23 and May 4, 2020, the Greek government established an economic and social ‘lockdown’ to prevent the spread of COVID-19. It was hypothesized that the unsafe environment activated the stress response of the Greeks during that time, while existing literature supports the development of psychosomatic disorders.
Aim: The research question is whether six biopsychosocial variables predict psychosomatic symptoms of the Greek general population during the ‘lockdown’.
Methods & Materials: A convenient sample of 1,158 -of whom 2 were excluded from the final analysis- Greeks participated electronically during the ‘lockdown’. Pearson’s r and a linear-multiple regression analyses were chosen to test the hypothesis. The participants answered a series of demographic questions, while the rest variables were measured through the following self-reported psychometric tools: ‘psychosomatics’ [PSSQ-29], ‘acute stress’ [ASDS], ‘psychological resilience’ [NMRQ], and ‘satisfaction with life’ [SWLS].
Results: Between the significant predictors, the first to appear is ‘acute stress’ (β= .66, p< .001), while ‘psychological resilience’ (β= .21, p< .001), ‘satisfaction with life’ (β= .06, p= .001) and ‘age’ (β= .04, p= .025) follow hierarchically.
Discussion: The findings are consistent to the background literature and previous relevant COVID-19 studies, with the exception of the findings regarding ‘gender’ -which was not found significant in the weightings-.
Conclusion: The model predicts the criterion with a large effect. The study is overall confirmatory to previous COVID-19 research regarding domestic general population, while the need for European studies that would include positive components on psychosomatic health is highlighted.

Management of Severe Diastasis Recti Abdominis by Abdominal Strengthening Exercise in Women after Postpartum Period: A Case Study
Authors: Charpot Vinal
Published: June 2021

Background: Abnormal gap between two rectus abdominal muscle at the level of umbilicus, above or below umbilicus called diastasis recti. It reduces the integrity and functional strength of the abdominal wall and can aggravate low back pain and later on pelvic instability. If the exercises are given to avoid the complications and reduce abnormal separation in early postpartum phase it will be most effective way to correct DRAM. But if these abdominal exercises have not been given on early phase then there will be no improvement in severe DRAM.
Materials and Methods: In this case study it was design to find out effect of abdominal strengthening exercise in women after postpartum period.39 year old lady was diagnosed with severe diastasis recti after one year of her last delivery. In this study finger palpation method was used to examine DRAM then abdominal strengthening exercises were given for 8 weeks.
Result: By finger palpation method it was found that this lady had severe DRAM at the level of umbilicus, above and below gap between two rectus abdominis muscle was more than 4 fingers. After completion of the exercise protocol it was found that there was no improvement in DRAM after 8 weeks but there is significant reduction in low back pain according to NPRS.
Conclusion: The result of this case study shows that abdominal strengthening exercises are not effective in reducing severe diastasis recti in after post partum period. But there was definite reduction in low back pain. So it is not support the prescription of an abdominal strengthening exercise in severe diastasis recti in very late post partum period of time.

Authors: Magret Muyide Abimbola , Taibat Oduneye Motunrayo
Published: June 2021

Introduction: Close relationship exists between diet, nutrition and dental health. Oral tissues are nutrition-dependent; inadequate diets can precipitate oral diseases and vice-versa. The study aimed to examine the effect of dietary pattern and nutritional status on the oral health of adults attending the Dental Clinic in University College Hospital, Ibadan.
Methodology: A descriptive cross-sectional study was conducted among 250 participants above 18 years; visiting the dental clinic. Questionnaire was used to obtain information on socio-demographic characteristics, oral habits and oral health-related dietary problems. Oral diagnosis and medical history were obtained from case notes. Validated Food Frequency and 24-Hour Recall questionnaires were used to collect information on frequency and pattern of food and nutrient intakes.
Result: Participants’ mean nutrient intakes were adequate for macronutrients but inadequate for nearly all micronutrients. Vitamin C showed statistical significance with Fracture, Vitamin B6 and B12 with Malocclusion, and Phosphorus and Zinc with Gingivitis. Oral problems affected food intake of 58.4% of participants, while 52.8% reportedly changed their diets due to oral problems. Coping mechanisms included chewing on one side of the jaw (40.8%), opting for liquid/soft foods (11.2%), avoiding hard foods (25.6%), omitting meat, fruits and vegetables from meals (21.6%).
Conclusion: The study establishes the prevalence of hidden hunger in patients with dental problem and the close relationship between nutrition and oral health. Nutrition education on the importance of adequate diet for good oral health is required, and treatment of oral health problems should involve Registered Dietitian Nutritionists.

Authors: Pradhan Mamata , Pokharel Basanti , Khadgi Anisha
Published: June 2021

Background: Tobacco product are products made entirely or partly of leaf tobacco as raw material, which are intended to be smoked, sucked, chewed, or snuffed. Tobacco use, among the adolescents is a growing public health problem the world has ever faced. More than 7 million deaths occur from tobacco use every day. Literature has shown that the prevalence of the tobacco uses was high among adolescents.
Methodology: A cross-sectional descriptive study design was used.150 respondents were taken as sample size. Probability sampling technique and self- administered questionnaire modified from GYTS, Version 2011 was used as a research instruments. Analysis was done using SPSSversion 16.
Findings: The study revealed that maximum 57.3% were male, majority 71.3% were from nuclear family, more than fifty 62.7% respondent's family uses tobacco products and majority75.8% tobacco is used by the respondent’s father. Majority 73.3% uses the hookah, more than half 64% gets tobacco from shop, and almost half 46.7% initiated tobacco product as experiment/curiosity and majority 74.7% uses in café. There is statically association found on frequency of tobacco used by the respondents with sex, residence of the respondent, time spend by the parents and initiated age of the tobacco. Greater strength of association on sex and initiated age of the tobacco use where lower strength of association on residence of the respondents and time spend by family.
Conclusion: About 15-20% of each higher secondary school students involve on the use of tobacco products. Gender, living place, time spend by the parents, initiated age of tobacco use, increase café cultural, easy availability and accessibility were the common factors for the use of tobacco among higher secondary students. So buying and selling tobacco products everywhere must be prohibited and adolescents should be restricted to use tobacco products in café or public places.

First European Polar Science Week
Authors: et al. Scientific Committee
Published: June 2021

During the high-level opening session, John Bell, European Commission Director, Directorate General Research & Innovation, European Commission, and Josef Aschbacher, ESA Director praised the cooperation between the EC and ESA, in the context of the Earth System Science Arrangement. They confirmed their willingness to advance towards a better coordination and integration of EC and ESA activities in Polar research. The European Union has been funding a significant number of Polar projects as part of the Framework programmes for Research and Innovation. In 2015, the funding of the EU-PolarNet project was instrumental as it enables stakeholders to coordinate activities across Europe. EU-PolarNet has delivered a number of key outputs among which the Integrated European Research Programme (EPRP). This report is the result of a process involving many players identifying key research and knowledge gaps, feeding into European Commission’s policy making. The launch of the new EU-PolarNet 2 project during the conference showed the willingness of the EU to sustain these coordination efforts. EU-PolarNet 2 will play a key role to reinforce the science to policy interface and to increase coordination of polar research activities at European level, with a better understanding of what is done at national level. EU-PolarNet 2 will also lead the coordination of the EU Polar Cluster in close cooperation with the ESA Polaractivities. The EU Polar Cluster, launched in 2016, has been extending in terms of number of projects (21 projects and 2 initiatives) and it confirmed its objective to reinforce cooperation across projects on a number of areas of common interest. Transnational cooperation of all involved actors (researchers and stakeholders) and European-wide coordination of Polar research efforts are decisively important, particularly in tackling major societal challenges such as climate change. Scientific knowledge has to be appropriately disseminated to inform policymakers with a high level of expertise and to support evidence-based policy making. The projects from the ESA Polar Cluster confirmed the need to work closer with the EU funded projects. This is fully supported by ESA, which launched a call for tender to facilitate innovative scientific developments through collaborative research and networking opportunities in the Polar research domain and in particular between the ESA and EU Polar Clusters.

The “Shaken Photos” Project as a Stimulus for Developing Creative Thinking with Preschoolers
Authors: Dermata Katerina
Published: June 2021

Using a digital camera to achieve a successful result requires from the user, first and foremost, to be familiar with the proper use of the medium and to have obtained basic knowledge of the principles of the art of photography. What is the result in those cases where the photographer either does not know the basic principles of photography or cannot apply them effectively in practice? Is the product considered a “failure” thus leaving photos with no clear and recognizable objects? This paper focuses on designing and implementing an applied educational intervention, themed on ”shaken” photos taken by preschoolers and using this material to create digital narratives. This case study examines "shaken" photos as an opportunity to develop imagination and creativity through photography.
Library Exhibitions and Visual Literacy
Authors: Gibbons Patti , Ng-He Carol
Published: June 2021

Library exhibitions showcase collections and can be laboratories where users apply key visual literacy skills, such as making close observations, practicing interpretation, and challenging assumptions. Library exhibitions facilitate self-directed inquiry and have a wide pedagogical range. At academic libraries, faculty include exhibition curation and viewing in their curriculum to promote scholarship and activism. Public libraries use exhibitions to cultivate civic interest and encourage intergenerational and multi-cultural learning. Across settings, exhibition experiences support visual learning, prompt critical thinking, and mobilize change. Through examining contemporary library engagement models such as the American College and Research Library’s Visual Literacy Competency Standards for Higher Education, this paper provides examples of exhibits that illustrate ACRL’s visual literacy benchmarks. Additionally, the paper provides a brief overview of recommendations for partnering with libraries to expand opportunities for visual learning.
China Belt and Road Initiative: Give-and-Take of Infrastructure Development in the North Africa Subregion
Authors: Dzekashu William G. , Anyu Julius N.
Published: June 2021

It is not a secret that Africa is richly endowed with raw materials, which has raised the stakes for foreign interests. The amplification of these riches has created a sense of urgency in developed nations to enter partnerships to have access to the resources. North Africa, though more advance than its sub-Saharan neighbors falls in the essential corridor of the Belt and Roads Initiative (BRI); and thus, requires infrastructure improvement to meet the overall BRI agenda. This yearning for infrastructure development in Africa has generally been met by China’s search for natural resources. The BRI is that infrastructure investment platform that allows for connectivity between member nations. This semi-systematic literature review identifies and appraises relevant research and collects and analyzes data about the impact of BRI on development in this subregion. Even though the BRI has shown some evidence of constructive growth in infrastructure connectivity, the opaque nature of the engagements has been the subject of harsh criticism; with some critics describing China’s motive as an attempt to recolonize Africa. Chinese partnerships in Africa have resulted in major investments and credit flows providing the much-needed resources to the BRI member countries to implement the very much needed development schemes, despite the main challenge that remains—sustenance of these extensive projects. The most significant implication of the BRI has been the concern about a possible conflict between China and the US. A key to averting open conflict between China and the US is through an alliance and coordinated response by Europe and the US.
Study of Light-Emitting Diodes
Authors: Mohamod Alkanze Kamal Ali ,
Published: June 2021

LEDs, or light-emitting diodes, are cheap, easy to purchase, and thus commonly used in physics instruction as indicators of electric current or as sources of light. In our opinion LEDs represent a unique piece of equipment that can be used to collect experimental evidence, and construct and test new ideas in almost every unit of a general physics course (and in many advanced courses) either as “black boxes” that allow students to study certain properties of a system of interest, as physical systems that allow students to learn an astonishing amount of physics that they usually do not encounter in a regular introductory physics course, and as non-traditional devices that allow students to construct concepts that are traditionally a part of a general physics course.

The general objective of this comparative study was the evaluation of three diagnostic techniques (sedimentation technique using centrifugation, filtration techniques using millipore filter and Ninhydrine stained filter paper) conventional approaches. This was carried out at Alzaidab, River Nile State, Northern Sudan on 93 school children. The study involved the collection of samples from school children of 7 years age and above. A questionnaire was distributed to collect data on gender, age and water contact activities. The examinations on all samples were carried out applying the methods previously mentioned. The results revealed that the overall prevalence rates of Schistosomahaematobium in Alzaidab Nile State were 16.1%, 24.7% and 24.7% using the centrifugation, syringe filtration millipore, ninhydrin – filter paper staining method respectively. According to gender, males showed higher prevalence rates than females using all the techniques mentioned and the highest prevalence rate in males (36.1%) was reported by the syringe filtration millipore and ninhydrin – filter paper staining method. According to age groups, the highest prevalence rate was reported among the group of children over 13 years of age, using all the techniques. The high prevalence rate (64.3%) among the above mentioned group (over 13 year’s of age) was shown by the syringe filtration millipore and ninhydrin – filter paper staining method. The highest prevalence among those who had water contact (32.9%) was shown by the syringe filtration millipore and ninhydrin – filter paper staining method.It was found that the syringe filtration millipore and ninhydrin – filter paper staining methods gave identical and reproducible results, yet the ninhydrin – filter paper staining does not fit for field practice since it can only be carried out in the laboratory.

Authors: Mohamed Abdalla Abdelrahman
Published: June 2021

A set of interatomic potentials has been derived for the determination of the most favorable sites of the oxygen substituted by fluorine atoms in SrMnO3. The calculations were performed using GULP code which implements interatomic potentials calculations within the ionic shell model. Initial investigations were made on SrMnO3 perovskite material. Our results for the parent SrMnO3 are in agreement with experimental data. This substitution is favorable to full Schottky disorder and the fluorine atoms are predicted to occupy sites trans to each other in the octahedron surrounding Mn.

Mineral deposits and valuable materials are deposited, concentrated, and purified by natural processes during long or short time, chemical weathering reactions is a major one. Satelliteimages exhibit distinct white horizon of high reflectance. Investigation of this phenomenonreveals that these areas were associatedwith the distal reaches of the major part of the drainage system. Exposures of the basement rocks include metasediments marl, marble, and other silicate rocks(granite, granodiorite,meta andesite,….etc) at high land where the proximal reaches of the drainage system. These rock were subjected to chemical disintegration process of hydrolysis for silicateconstituent and dissolutionfor carbonate constituent and consequently these material were transportedby the drainage system as colloidal (kaolinite) and dissolved material(calcium cation and bicarbonate), eventually these material were deposited due to evaporation at flash delta to form the kaolinite carbonatesoil at Alfirjah area and it’s vicinity. Field observations in addition to rock and soil sample analysis forearm the above mentioned hypothesis.

Croton tiglium is commonly used to treat constipation in African countries including Sudan. This study aim to evaluate histopathologic changes in Liver tissue after treated with Croton tiglium mixed with animals diet in male albino rats. The rats were divided into three groups containing of 6 rats per group for each , and they treated as follow : Group I serve as control, Group II & III: Were given a mixture of animals diet with Croton tiglium diet at concentrations of 10% and 20% respectively. Treatment of rats with 10% of Croton tiglium showed no remarkable damages or signs of lesions on specimens taken from animals for histopathological examinations ,but rats under 20% treatment showed some abnormal (alterations) .Therefore, the fruits of Croton tiglium at 20% are toxic to rats .Further studies are necessary to isolate and characterize the bioactive constituents in the fruits and to elucidate modes of compound actions and interactions.

The reputation of a college can cause many students who want to register and study at the college. Therefore, there is a very good impact related to many students, the first is income, and the second is academic and student activities. The purpose of this study was to examine and analyze the effect of institutional reputation and the availability of information on trust. Besides that, to analyze the effect of trust on the intention to be a student. This research was conducted on students of the Faculty of Economics, and Islamic Business IAIN Salatiga accepted and re-registered. The sample in this study was 151 students using the purposive sampling method. The results showed that the availability of information did not affect trust. However, the institution's reputation had a positive effect on trust, and trust had a significant effect on the intention to be a student of the Islamic Economics and Business Faculty IAIN Salatiga.
Automated mechanical ventilation using Adaptive Support Ventilation versus conventional ventilation including ventilator length of stay, mortality, and professional social aspects of adoption of new technology.

Background Automation of mechanical ventilation allows for reduction of variation in patient management and has the potential to provide increased patient safety by strict adherence to computer driven ventilator protocols. Methods: A retrospective, observational study compared a group of 196 of general ICU patients managed exclusively on automated mechanical ventilation, adaptive support ventilation (ASV), to another group of 684 managed by usual, non-automated mechanical ventilation (No ASV). The data was collected in a unique access database designed to collect data for assessment of mechanical ventilation outcomes in a small medical center ICU. Results: The length of ventilator stay was non-significant between both groups, (81.7 ± 35.2 hours) in the ASV group; vs. (94.1 ± 35.1 hours) in the No ASV. Percent mortality was significantly less in the ASV group, 8.6% compared to 27.3% in the No ASV. Conclusion: Automated ventilation appears to be a safe ventilator strategy; however, cause effect relationships cannot be determined without further, more sophisticated studies. Keywords: Closed loop ventilation, ASV, Ventilator length of stay, Percent minute ventilation

O armazenamento de água de uma bacia de drenagem determina a sua segurança hídrica. A quantidade de água retida na bacia pode ser medida por meio do cálculo do balanço hídrico, definido pelas entradas de água subtraídas das saídas. As medidas hídricas de entrada e saída em uma bacia de drenagem são onerosas, o que torna o uso de dados de sensoriamento remoto uma ferramenta de grande impacto socioeconômico para fins de gestão. Somado a isto, tem-se que estudos de disponibilidade hídrica com sensores orbitais são relativamente escassos para a Bacia do Alto Paraguai (BAP). Dessa forma, a partir do processamento de dados de precipitação do Tropical Rainfall Measuring Mission (TRMM) e de evapotranspiração do MODIS Global Evapotranspiration Project (MOD16), o presente trabalho traz uma estimativa do balanço hídrico da BAP com sensores orbitais. Os resultados indicam que a BAP apresentou um superávit hídrico anual entre 2000 e 2014, muito embora os parâmetros hídricos anuais sejam pouco correlacionados. No entanto, parece haver fenômenos atmosféricos- -climáticos que maximizam a correlação entre os parâmetros hidrológicos e a anomalia de temperatura com atrasos de 2 a 5 anos, presumivelmente via teleconexões climáticas defasadas com QBO e ENSO. Embora o balanço realizado mostre um excedente hídrico na bacia, esta condição pode estar se alterando devido às mudanças climáticas globais.

A gestão eficaz do solo requer uma compreensão dos seus aspectos físicos, químicos e sua distribuição espacial. Esse estudo buscou, através da distribuição espacial da resistência do solo à penetração mecânica, elaborar um índice de fragilidade ambiental e utilizá-lo em uma carta de fragilidade ambiental para a Área de Proteção Ambiental (APA) de Botucatu. As metodologias de análise empírica da fragilidade ambiental, geoestatística, análise de decisão multicritérios e álgebra de mapas foram empregadas nesse estudo. Medidas de resistência do solo à penetração mecânica, a declividade, os tipos de solos e uso do solo foram usados para gerar a carta de fragilidade ambiental. Os resultados mostraram que 32,5% da área amostral se encontraram dentro de classes baixas de fragilidade e 67,57% se encontraram em classes de fragilidade de média a muito alta. A resistência do solo à penetração mecânica, que é uma característica natural de diferentes solos pode ser usada como um critério dentro de uma análise de fragilidade. Foi evidenciado que existe uma relação da resistência do solo à penetração mecânica com a declividade e o uso do solo, onde diferentes tipos de uso e seus manejos modificam essa resistência natural ao ponto de se tornar uma fragilidade.
