Apreciação do povoamento do Neolítico Inicial na Baixa Bacia do Douro. A Lavra I (Serra da Aboboreira) como caso de estudo
Authors: Sanches Maria de Jesus
Published: November 2020

This text is devoted to the discussion of the archaeographic documentation of the Early Neolithic archaeological site of Lavra I (Serra da Aboboreira; Aboboreira Mountain), bringing into focus the phenomena of sedimentation and formation of the archaeological record, the type of occupation and the explanation of the C14 dates. It also discusses how Lavra I is inscribed at the beginning of the neolithicization process in the North of Portugal and the Lower Douro basin, highlighting, in Serra da Aboboreira, the possibility of a temporal and spatial relationship with the oldest barrows (mamoas), in the 2nd quarter of the 5th mil. B.C.
O sítio arqueológico de Castanheiro do Vento. Da arquitectura do sítio à arquitectura de um território
Authors: Cardoso João Muralha
Published: November 2020

Castanheiro do Vento is an archaeological site with an occupation that covers the entire 3rd millennium and the first half of the 2nd BC. It’s located in the municipality of Vila Nova de Foz Côa, district of Guarda and has been investigated by a vast team. With this paper, we intend to present some reflections on how to build in Castanheiro do Vento and share some ideas on the relationship between doing architecture on the site and the idea of architecting a larger space, a territory. If we accept that building is a way of being in the world, architecture will always have connections to that world and consequently to its organization. It is important to bear in mind that during recent prehistory, the landscape of the Alto Douro was being changed by communities in the process of consolidating an agro-pastoral system. This territorialization process led to a diversified occupation of the landscape. Some points of this landscape were marked by the construction of walled enclosures, others, which are almost invisible and still others, which occupy great natural markers of the landscape
A cividade de Bagunte. O estado atual da investigação
Authors: Almeida Pedro Brochado de
Published: November 2020

The Cividade of Bagunte is the most publicized archaeological site of the municipality of Vila do Conde. Located on a mound with great visibility over the territories to the north and south of the Ave River it called the attention and interest of various archaeologists such as Ricardo Severo and Martins Sarmento, in the end of the 19th century, and F. Russell Cortez in the 40’s of the next century. F. Russell Cortez organized digging campaigns at the site that uncovered a mixture Castrejo and Roman type buildings and structures, distributed by orthogonal spaces that already have the seal of a Roman influence in the region. The most recent archeological campaigns give us a higher precision to determine its evolution as a settlement, despite the many questions that remain unanswered
Zoomorfos na cerâmica da Idade do Ferro no NW Peninsular: inventário, cronologias e significado
Authors: Oliveira Nuno , Seoane Cristina
Published: November 2020

In the Iron Age ceramics studies on the NW of Iberian Peninsula, had number of pieces that feature decoration with zoomorphic motifs stand out. Probably their relative rarity within the ceramics in this period, where geometric motifs dominate, become of special interest as a social and ideological instrument for the society. The aim of this study was to carry out the first inventory of this type of motifs associated with its geographical context and its chronology and the functionality, social and symbolic value of this representation in that society. After organizing the data obtained, these elements were compared with the decoration in metals and other fabrics
Cultivos de Época Romana no Baixo Sabor: continuidade em tempos de mudança?
Authors: Tereso João Pedro , Pereira Sérgio Simões , Santos Filipe , Seabra Luís , Vaz Filipe
Published: November 2020

During the excavation of eight roman sites in the Lower Sabor valley, sediment samples were recovered and carpological analyses were carried out in order to obtain data regarding agriculture and storage. Naked wheat was the most frequent crop during the Roman period, but barley and millet were also relevant. The presence of grapes is documented while pulses and other wild edible plants were scarce. These results contrast with those found in other regions of Northwest Iberia, both in Roman Times and the Iron Age, where hulled wheats were particularly relevant. Current available data does not allow us to know the reason behind the specificities of the Sabor valley’s sites, although some environmental and cultural aspects may provide suitable explanations

Published: November 2020

Revealing the effect of mixed beech and hornbeam stands on herb layer diversity is essential for sustainable forestry and biodiversity conservation since little is known in Hyrcanian forests. So, we studied the effects of such stands on understory diversity and soil physico-chemical properties in Hyrcanian forests of Iran. Forty sampled plots were established by random systematic sampling method with a regular 100 m × 200 m grid. At each sample point we recorded species identity and percent cover of each tree layer and herb layer species within plots of size 400 m2 (20 m × 20 m) and 100 m2 (10 m ×10 m) respectively. Soil samples were taken from 0 cm -10 cm and 10 cm - 30 cm soil depths. Cluster analysis was used to classify the samples based on the floristic composition data. Also detrended correspondence analysis (DCA) method was employed to assess the relationship between vegetation and environmental variables. There was no significant difference in terms of species richness, and diversity between mixed beech stands and hornbeam stands, but cluster analysis indicated that these stands were separated in two different groups based on herb layer species composition. DCA results showed that litter thickness, soil texture, total nitrogen, and organic carbon in the first layer were considered effective environmental variables in the distribution of sample plots in two stands. We observed that tree layer composition and soil characteristics were crucial contributors to variations of understory species composition which may be changed by forest management approaches over time. Tree layer composition and soil attributes can be considered effective factors for controlling and assessment of understory plant species composition. These findings could provide guidelines for conserving plant species diversity within any framework of sustainable forest management in Hyrcanian forests.

Conhecidas as diferenças ergológicas, isto é, fixados os diferentes tipos de trabalho, há que cogitar das diferenças individuais. Quando observamos um grupo de indivíduos podemos notar, logo à primeira vista, como são pronunciadas as diferenças entre eles. Não há dois rigorosamente iguais. Pela compleição, pelos gestos, pelo timbre de voz e por outros traços cada um revela tua individualidade própria e inconfundível. Aqui encontramos um temperamento calmo, imperturbável, capaz de enfrentar as situações mais difíceis, sem perder a serenidade, a lucidez, o senso de exatidão no pensar e no agir; acolá surpreende-nos a extraordinária capacidade que permite a outro indivíduo concentrar a atenção, simultaneamente, em várias coisas com um espírito de minúcias que lhes apreende os mínimos detalhes; mais adiante deparamos com alguém dotado de excepcional habilidade para lidar com pessoas, captar lhes a simpatia, desarmar lhes o ânimo e fazê-las suportarem, pacientemente, as mais incomodas situações. Essas multiformes características da personalidade apresentam, ainda, variações de intensidade e grau. As diferenças individuais não são apenas qualitativas, mas, também, quantitativas.

A Bayesian Network–Based Browsing Model for Patients Seeking Radiology-Related Information on Hospital Websites: Development and Usability Study
Authors: Suzuki Ryusuke , Suzuki Teppei , Tsuji Shintaro , Fujiwara Kensuke , Yamashina Hiroko , Endoh Akira , Ogasawara Katsuhiko
Published: November 2020

Background

An increasing number of people are visiting hospital websites to seek better services and treatments compared to the past. It is therefore important for hospitals to develop websites to meet the needs of their patients. However, few studies have investigated whether and how the current hospital websites meet the patient’s needs. Above all, in radiation departments, it may be difficult for patients to obtain the desired information regarding modality and diagnosis because such information is subdivided when described on a website.

Objective

The purpose of this study is to suggest a hospital website search behavior model by analyzing the browsing behavior model using a Bayesian network from the perspective of one-to-one marketing.

Methods

First, we followed the website access log of Hokkaido University Hospital, which was collected from September 1, 2016, to August 31, 2017, and analyzed the access log using Google Analytics. Second, we specified the access records related to radiology from visitor browsing pages and keywords. Third, using these resources, we structured 3 Bayesian network models based on specific patient needs: radiotherapy, nuclear medicine examination, and radiological diagnosis. Analyzing each model, this study considered why some visitors could not reach their desired page and improvements to meet the needs of visitors seeking radiology-related information.

Results

The radiotherapy model showed that 74% (67/90) of the target visitors could reach their requested page, but only 2% (2/90) could reach the Center page where inspection information, one of their requested pages, is posted. By analyzing the behavior of the visitors, we clarified that connecting with the radiotherapy and radiological diagnosis pages is useful for increasing the proportion of patients reaching their requested page.

Conclusions

We proposed solutions for patient web-browsing accessibility based on a Bayesian network. Further analysis is necessary to verify the accuracy of the proposed model in comparison to other models. It is expected that information provided on hospital websites will be improved using this method.
Integration of Technology in Medical Education on Primary Care During the COVID-19 Pandemic: Students’ Viewpoint
Authors: Paul Nadine , Kohara Sae , Khera Gursharan Kaur , Gunawardena Ramith
Published: November 2020

The COVID-19 pandemic has forced medical schools and clinicians to transition swiftly to working online, where possible. During this time, final-year medical students at King’s College London, England, have received some of their general practice teachings in the form of virtual tutor groups. The predominant feature of such groups is online patient simulations, which provide students a valuable experience to help gain insight into current clinical practice amid the pandemic and inform how their practices as incoming junior doctors would continue. Even in the absence of face-to-face teaching and clinical placements, students have been able to hone their medical knowledge and soft skills through these virtual, simulated consultations. They have been exposed to a new consultation style while in a safe and collaborative learning space. Here, we explore how medical students have benefited from these virtual tutor groups and how similar small-group online teaching opportunities can add value to the medical curriculum in the future.
An Intervention to Enhance Social, Emotional, and Identity Learning for Very Young Adolescents and Support Gender Equity: Protocol for a Pragmatic Randomized Controlled Trial
Authors: Cherewick Megan , Lebu Sarah , Su Christine , Dahl Ronald E
Published: November 2020

Background

The onset of puberty is a pivotal period of human development that is associated with significant changes in cognitive, social, emotional, psychological, and behavioral processes that shape identity formation. Very early adolescence provides a critical opportunity to shape identity formation around gender norms, attitudes, and beliefs before inequitable gender norms are amplified during and after puberty.

Objective

The aim of the Discover Learning Project is to integrate strategic insights from developmental science to promote positive transformation in social, emotional, and gender identity learning among 10- to 11-year-olds in Tanzania. Through a pragmatic randomized controlled trial, the intervention scaffolds the development of critical social and emotional mindsets and skills (curiosity, generosity, persistence, purpose, growth mindset, and teamwork) delivered by conducting 18 after-school, technology-driven, experiential learning sessions in small, mixed-gender groups.

Methods

The Discover Learning Intervention is a 3-arm randomized controlled trial that will be delivered to 579 participants selected from four public primary schools in Temeke District, Dar es Salaam, Tanzania. Randomization will be done at the individual level into 3 treatment groups receiving incremental intervention components. The treatment components include Discover Learning content curated into child-friendly videos, facilitated discussions, and a parent-child workbook, to be implemented over two phases, each 6 weeks long. A baseline survey will be administered to participants and their parents prior to the intervention. The process will be observed systematically, and data will be collected using surveys, in-depth interviews, observations, and focus group discussions with adolescents, parents, teachers, and facilitators conducted prior, during, and after each implementation phase.

Results

This study builds on formative and pilot studies conducted with the target population to inform the design of the intervention. The results will generate new evidence that will inform strategies for achieving scale in Tanzania and provide insights for replication of similar programs that are invested in gender-transformative interventions in peri-urban, low-resource settings.

Conclusions

The Discover Learning Intervention makes an important contribution to the field of adolescent developmental science as an intervention designed for very young adolescents in a low-resource setting.

Association between Social Media Use for Health Purpose and Depressive Symptoms: A Cross-Sectional Survey (Preprint)
Authors: Lee Hee Yun , Luo Yan , Won Cho Rong , Lee Jiyoung , Baik Jeongwon
Published: November 2020

BACKGROUND

The use of social media or social networking sites (SNS) is increasing across all age groups, and one of the primary motives of using SNS is to seek health-related information. Although previous research examining the effect of SNS use on depression exist, studies regarding the effect of SNS use for health purpose on depression is limited.

OBJECTIVE

Our study aims to explore the relationship between SNS use for health purpose and depression across the four age groups (18-34 years old, 35-49 years old, 50-64 years old, and above 65 years old).

METHODS

A sample of 6,789 adults aged 18 and older was extracted from a 2017 and 2018 Health Information National Trends Survey (HINTS). Univariate and bivariate analyses to examine the association between each variable and four age groups were conducted. Multiple linear regression analyses to predict depression level among participants with use of SNS for health purpose were conducted.

RESULTS

SNS use for health purpose and depression were positively associated for three age groups but not for those 65 years or older (=0.13, P<0.05; =0.08, P<0.05; =0.09, P<0.05). Income and self-reported health status indicated an inverse relationship for all age groups. The relationship with marital status differed based on age group with 18 and 34 years old showing an inverse relationship (=-0.13, P<0.01) while 65 years or older showing a positive relationship (=0.06, P<0.05). Gender was positively associated among those in the 35-49 years old (=0.09, P<0.05) and 65 years or older (=0.07, P<0.05). Being Non-Hispanic White was positively associated with depression among 50-64 years old (=0.07, P<0.001) and 65 years or older (=0.08, P<0.05).

CONCLUSIONS

Age-tailored education on determining accurate and reliable information shared via SNS is needed to reduce depressive symptoms.
Crush Injury Risk Awareness, Prevention and Minimisation in Load Shifting Operations
Authors: Skiba Richard
Published: November 2020

This article considers injuries related to crushing and methods of prevention and minimisation of such injuries, particularly from the perspective of plant operations, where a crush injury occurs when the body or a body part is trapped, pinched or jammed under or between objects (Victoria State Government., 2020). A safe system of work, underpinned by worker awareness, should be implemented and maintained in all load shifting operations in order to minimise or prevent crush injury risks. Employers and workers should participate in inductions, safety meetings and consultation activities to ensure that they are aware of best practices to control crush hazards.

Radiometric resolution and dynamic range of aerial and space images, obtained for monitoring and mapping purposes
Authors: Anikeeva I.A.
Published: November 2020

The dynamic range and radiometric resolution are among the most important indicators of aerial and space images’ fine quality. Gradation properties are of particular importance for aerial and space images, obtained for monitoring and mapping purposes, because the completeness and quality of the information on the earth’s surface objects depend on them, the accuracy of brightness features reproduction of earth’s surface objects. The author discusses various approaches to defining the concepts of dynamic range and radiometric resolution; the most proper definitions of these terms are given in the context of estimating the image’s gradation properties. The expediency of separating the concepts of nominal, actual and useful (effective) radiometric resolution is shown; their definitions are given. Methods of dynamic range and radio-metric resolution numerical estimation based on a histogram are shown. Absolute and relative indicators are considered. The advantages of using relative indicators are shown. Examples of the dynamic range and radiometric resolution evaluation are given basing upon the images obtained by ‘‘Canopus-B’’ spacecraft.
THE STUDENTS' MATHEMATICAL PROBLEM-SOLVING ABILITIES, SELF-REGULATED LEARNING, AND VBA MICROSOFT WORD IN NEW NORMAL: A DEVELOPMENT OF TEACHING MATERIALS
Authors: Pertiwi Citra Megiana , Rohaeti Euis Eti , Hidayat Wahyu
Published: November 2020

The new normal period makes ICT-based education the spearhead of the implementation of learning. This becomes an obstacle and a challenge for students, especially in the mathematical problem-solving ability (MPSA), which is very important for students because it is a prior mathematical ability and is included in HOTS. Self-regulated learning in mathematics (SRL) also has a significant role in adapting to learning in the new normal and influences students' mathematical learning outcomes. However, the facts on the ground show that these two abilities are still low. To solve this problem, the researchers developed VBA Microsoft Word-based teaching materials on the relevant polyhedron materials for use so that learning would be more optimal. The method used in this research is an experimental method with a pretest-posttest control group design. The population is all the students in Cimahi City, while the sample is two classes randomly selected. This study indicates that VBA Microsoft Word-based teaching materials are appropriate to be applied in the new normal period, as indicated by the results of the achievement and improvement of MPSA and SRL of students is better than ordinary learning. There is an association between MPSA and SRL and positive response even though they still have difficulty making mathematical models on MPSA questions. Students are more enthusiastic in learning and don't get bored quickly; in line with the challenges of the new normal, the industrial revolution 4.0, and the learning curriculum, learning is more structured, interactive, effective, and efficient.
On-line fault diagnosis model for rigid ceramic filters based on outlet concentration and dynamic pressure
Authors: Liu Longfei , Ji Zhongli , Luan Xin
Published: November 2020

Sudden fractures in rigid ceramic filter tubes hinder the stable
long-term operation of advanced power-generation processes. In this
study, Time difference of arrival (TDOA) of dynamic pressure in the
inner wall of filter during pulse jet cleaning process and outlet
concentration with diameter of leakage during filtration and pulse jet
cleaning process are investigated using high frequency sensors and
optical particle spectrometry. The outlet concentrations measured under
different leakage agreed with the theoretical values, with the peak
outlet concentration being 2.5 times greater than stable outlet
concentration. There is a linear relationship between leakage aperture
and theoretical outlet concentration in leaking ceramic filter tubes. A
positioning model that can precisely locate the leaking ceramic filter
tube using the time difference in the dynamic pressure as measured at
different positions is established. This research can quickly and
accurately determine whether a ceramic filter tube is broken and
location of breakage.
Importance of Chewing Simulators in the Difference of Test Results of Dental Materials. Systematic Review
Authors: Jr orlando Santiago , Ferreira Marcus Vinicius , Huebner Rudolf
Published: November 2020

Objectives: With new dental materials constantly being launched on the
market, the number of researches on the properties of dental materials
have increased substantially in the past few years. However different
results about physical properties of the same material are frequently
found in the literature. In an endeavor to elucidate the cause(s) of
these disparate results, a review of the literature published in the
last five years was conducted, to investigate whether these differences
are due to the testing machines - also called chewing simulators – used
in the studies. Data: We searched for data of indicators of test
accuracy, maintenance of test parameters during all experiments,
reproducibility of test and standards in the articles, or in the
manufacturers’ sites. Sources: The database searched was CAPES PORTAL
(http://www-periodicos-capes-gov-br.ez27.periodicos.capes.gov.br) Study
Selection: In the search, the following keywords were used: “bite
force” AND “simulator”, “chewing simulator” and “mastication
simulator”, and the publication filter date of “January 1, 2016”. As
a result, 100 articles were selected and recovered in order of
appearance by using the filter “relevance”. Conclusion: based on the
data obtained in this review, the disparate results of experiments with
dental materials appeared to be more related to the test conditions
rather than with the testing machines.

Authors: Yasuhara Jun , Watanabe Kae , Takagi Hisato , Sumitomo Naokata , Kuno Toshiki
Published: November 2020

Background: Multisystem inflammatory syndrome in children (MIS-C)
associated with COVID-19 has been increasingly recognized. However, the
clinical features of MIS-C and the differences from Kawasaki disease
remain unknown. The study aims to investigate the epidemiology and
clinical course of MIS-C. Methods: PubMed and EMBASE were searched
through August 30, 2020. Observational studies describing MIS-C were
included. Data regarding demographic features, clinical symptoms,
laboratory, echocardiography and radiology findings, treatments, and
outcomes were extracted. Study-specific estimates were combined using
one-group meta-analysis in a random-effects model. Results: A total of
27 studies were identified including 917 MIS-C patients. The mean age
was 9.3 (95% confidence interval [CI], 8.4-10.1). The pooled
proportions of Hispanic and Black cases were 34.6% (95% CI, 28.3-40.9)
and 31.5% (95% CI, 24.8-38.1), respectively. The common manifestations
were gastrointestinal symptoms (87.3%; 95% CI, 82.9-91.6) and
cardiovascular involvement such as myocardial dysfunction (55.3%; 95%
CI, 42.4-68.2), coronary artery aneurysms (21.7%; 95% CI, 12.8-30.1)
and shock (65.8%; 95% CI, 51.1-80.4), with marked elevated
inflammatory and cardiac markers. The majority of patients received
intravenous immunoglobulin (81.0%; 95% CI, 75.0-86.9), aspirin
(67.3%; 95% CI, 48.8-85.7), and corticosteroids (63.6%; 95% CI,
53.4-73.8) with a variety of anti-inflammatory agents. Although
myocardial dysfunction improved in 55.1% (95% CI, 33.4-76.8) at
discharge, the rate of extracorporeal membrane oxygenation use was 6.3%
(95% CI, 2.8-9.8) and the mortality was 1.9% (95% CI, 1.0-2.8).
Conclusion: Our findings suggest that MIS-C leads to multiple organ
failure, including gastrointestinal manifestations, myocardial
dysfunction and coronary abnormalities, and has distinct features from
Kawasaki disease.
Reflexões acerca da educação do negro no Brasil: um enfoque para a mulher negra

Published: November 2020

O referido estudo busca trazer breve reflexão acerca da trajetória da educação do negro no Brasil do período colonial aos dias atuais, com enfoque para a mulher negra. Trata-se de resultado preliminar de um estudo exploratório de natureza qualitativa. Os resultados apontam uma trajetória de luta pelos direitos negados e uma constante resistência aos ajustes das classes dominantes que solidificaram uma sociedade moldada no pensamento eurocêntrico, hegemônico, racista, em que a educação, desde o período colonial, foi pensada e direcionada aos portugueses e, após esse período, às classes dominantes, sempre visando a manutenção dos privilégios, restando à população negra a dominação e exploração. Além disso, a mulher negra foi subjugada de forma mais dolorosa, pois sofreu e ainda sofre preconceito e discriminação de cor e gênero.

Published: November 2020

Macroporous silica ceramic was obtained using clay and diatomite. Boric acid
as a low-cost additive in the amount of 1 wt% was used. These porous
materials were obtained at low forming pressure (40-80 MPa) and lower
sintering temperature (850-1300 ?C) for 4h in air. The influence of boric
acid, forming pressure, and sintering temperature on the microstructure,
porosity parameters, and mechanical properties of obtained porous monoliths
were investigated. As-received and the modified samples were characterized
by X-ray diffraction, FTIR, SEM, and mercury porosimetry measurements. As
for modified clay and diatomite, they were pressed at 60 MPa and then
sintered at 1150 ?C, obtaining porosities of about 10 % and 60 %,
respectively. Both of the analyzed samples had the pore diameter in the
range of macroporous materials. The pore diameters of clay samples are
ranging from 0.1-10 ?m, whereas the pore diameter of diatomite samples was
slightly lower with values ranging from 0.05-5 ?m. Modified diatomite
samples have a lower Young modulus in comparison to modified clay samples.
Factor structure of the scale of parents’ self-assessed competence for parents’ role
Authors: Maric-Jurisin Stanislava , Malcic Borka
Published: November 2020

Competent parents feel well in their role, and the experience of their
competence reflects on all the spheres of their life. In Serbia, it was
noticed that a small number of researches were conducted on this topic. There
is no validation of instruments that would allow conducting research using a
reliable and valid measure of competence of parents. The aim of this
investigation was to determine the factor structure of Parental competence
scale [Ljubetic, 2007]. The survey involved 575 parents of pre-school
children. The paper presents two solutions of the questionnaire: four-factor
and two-factor. The obtained results indicate that on the initial check of
the four-factor solution, the obtained reliability of the instrument was low
and that there would be no changes after the exclusion of certain items. The
results of two factor solution shows that only the first factor related to
incompetence in parenting can be used as a reliable measure. Further item
analysis confirmed that the reliability of the other factor (competence)
would not be increased even by the exclusion of certain items. The conclusion
is that the scale can be used only in a short form with 7 items exclusively
in the self-assessment of parents? incompetence. The recommendation is also
given in the paper in the form of supplementing the factors of parents?
competence with the appropriate number of items.

Protein citrullination plays a role in several autoimmune diseases. Its involvement in murine and human type 1 diabetes has recently been recognized through the discovery of antibodies and T-cell reactivity against citrullinated peptides. In the current study, we demonstrate that systemic inhibition of peptidylarginine deiminases (PADs), the enzymes mediating citrullination, through BB-Cl-amidine treatment, prevents diabetes development in NOD mice. This prevention was associated with reduced levels of citrullination in the pancreas, decreased circulating autoantibody titers against citrullinated glucose-regulated protein 78, and reduced spontaneous neutrophil extracellular trap formation of bone marrow–derived neutrophils. Moreover, BB-Cl-amidine treatment induced a shift from Th1 to Th2 cytokines in the serum and an increase in the frequency of regulatory T cells in the blood and spleen. In the pancreas, BB-Cl-amidine treatment preserved insulin production and was associated with a less destructive immune infiltrate characterized by reduced frequencies of effector memory CD4+ T cells and a modest reduction in the frequency of interferon-γ–producing CD4+ and CD8+ T cells. Our results point to a role of citrullination in the pathogenesis of autoimmune diabetes, with PAD inhibition leading to disease prevention through modulation of immune pathways. These findings provide insight in the potential of PAD inhibition for treating autoimmune diseases like type 1 diabetes.

Stainless steel has been used as a successful biomaterial for decades. In this study, a pulsed nanosecond laser was used to create patterned surfaces of stainless steel coupons to study the effect of patterning on fluid retention and biocompatibility studies of laser patterned and control surfaces. An AVIA 355 nanosecond pulsed laser was used with different laser parameters to create unique “peak and valley” structures (uniform textured surface) on stainless steel coupons of size of 1 × 1 × 0.1 cm3. The surface structural changes can be attributed to the Gaussian beam profile of the laser. The coupons were observed under a scanning electron microscope to understand the change of the material surface profile. An optical profilometer was used to measure the surface roughness and compare it with a nontextured or control surface. The contact angle measurement showed a decrease in the contact angle, reduced to 71.6° from 82.2° making the patterned surface more hydrophilic. A biocompatibility study of the stainless steel was performed to evaluate the effect of surface modification on its impact on biocompatibility. The cell viability of the patterned sample was 94% as compared to 84% for the unpatterned surface. A simulation of the process was run using flow3d® to understand the behavior of the material during the texturing process. The results obtained from the simulation process were compared with the experimental data and found to be in good agreement. The effects of Gaussian beam, vapor pressure, and overlapping of the beam were also analyzed in the simulation process.

Temperature-entropy diagrams for calculating cycles of refrigerating machines using refrigerant mixtures
Authors: Bukin Vladimir Grigorievich , Ezhov Alexey Vasilievich , Andreev Aleksander Ivanovich
Published: November 2020

The article represents the advantages and disadvantages of refrigeration machines operating on non-azeotropic refrigerant mixtures. There has been illustrated their specific feature in comparison with pure substances: they are non-isothermal during phase transitions. It can be effective when cooling or heating flows that significantly change the temperature, and ineffective when working with volumes, where it is necessary to maintain a constant temperature. In the first case there takes place a decrease in the internal irreversibility of heat transfer processes in evaporators and condensers; in the second case - an increase. When using mixed refrigerants, it is possible to simultaneously obtain several temperature levels in a single-stage machine at the same pressure in the evaporators, they can obtain low boiling points of the refrigerant without vacuum in the evaporator and regulate the refrigeration capacity of the machine by changing the composition of the mixture. The prospects of using mixtures of working bodies of refrigerating machines have been proved. The diagrams T-S, T-ξ, i-ξ are presented allowing to calculate the cycle of the machine, to determine its operating parameters and to calculate the technical and energy characteristics. The developed thermal diagrams make it possible to accurately examine the dynamics of the boiling and condensation processes of a binary mixture, show the change in the concentration of the mixture in the vapor and liquid phases and make it possible to construct and calculate the cycle of a refrigeration machine operating on a mixed refrigerant. Examples of constructing cycles of two schemes of refrigeration machines operating on a mixed refrigerant are considered: with separation of the working substance flow and without separation. Methods for calculating the cycle are provided

Sobre o sofrimento humano: uma hermenêutica da carne a partir de Richard Kearney e Paul Ricoeur | On human suffering: a carnal hermeneutics based on Richard Kearney and Paul Ricoeur
Authors: Zeferino Jefferson , Fernandes Marcio Luiz
Published: November 2020

O texto, metodologicamente pautado numa análise bibliográfica, apresenta, no horizonte do distanciamento social causado pela pandemia de Covid-19, uma reflexão acerca da hermenêutica da carne, conforme proposta por Richard Kearney em diálogo com o pensamento de Paul Ricoeur em sua abordagem do sofrimento humano e a partir de textos selecionados que corroboram com a discussão ricoeuriana iniciada pelo filósofo irlandês. A tensão entre encarnação e excarnação (desencarnação) é problematizada na direção de que uma sabedoria prática é solicitada pela experiência humana de sofrimento no caminho de humanização do humano por meio da sensibilização à alteridade. A encarnação, como tema de uma teologia pública, portanto, é considerada na relação do ser consigo mesmo, com o outro, com os outros (coletividade) e com o mundo, além de ser compreendida como um tornar- -se profundamente humano na esteira bonhoefferiana. A capacidade de importar-se com o sofrimento do outro, portanto, é constitutiva de uma inteligência da pele. Isso posto, este trabalho se estrutura da seguinte maneira: (a) O conceito e o percurso teórico de uma hermenêutica carnal; (b) A questão do sofrimento humano a partir de Ricoeur; (c) Considerações acerca da relação entre humanização, sensibilização e encarnação à luz de uma hermenêutica da carne, seguidas de uma apresentação sintética dos resultados à guisa de conclusão.
