La Theoxenia Eleusina diFasti4.503‒62: Alcune considerazioni sulle fonti e sui caratteri distintivi del testo ovidiano
Authors: Pasquali Luciano
Published: June 2021

The two versions of the myth of Ceres and Proserpina produced by Ovid atFasti4.417‒618 andMetamorphoses5.341–661 have played an exceptionally important role for the knowledge and transmission of this episode in Western culture, from an anthropological and religious point of view but above all from an artistic and literary one. Nonetheless, the complexity of the two texts still confronts modern readers with questions and points to investigate. The present article, devoted specifically to the episode of the divine hospitality of Celeus atFast.4.503–62, examines Ovid’s use of the narrative pattern of θεοξενία with particular reference to its models, lexicon, literary paradigms, intertextuality and the author’s self-referentiality. The starting-point and premise of the study is a re-examination of Ovid’s sources, which is followed by an analysis of the modes of rewriting the myth; finally, some singular details will be highlighted that are present in the text of theFasti, which could be assigned an intent that is defamiliarising and ironic, if not downright parodistic.

In the paper the fragment transmitted by Ausonius and ascribed to Quintus Cicero on the signs of the zodiac is analysed in terms of language, transmission history and intertextuality. As a result, authorship by Q. Cicero must be regarded with great scepticism.
Application of the Folgar–Tucker model to predict the orientation of particles of different aspect ratios in polymer suspensions
Authors: Kattinger Julian , Joas Sebastian , Willems Fabian , Kreutzbruck Marc , Bonten Christian
Published: June 2021

The increasing requirements on plastic parts demand a rising use of combined functional and reinforcing materials. Therefore, often reinforcing particles with different aspect ratios are added to the plastic as additive mixtures. However, the engineering design process of reinforced parts requires an early knowledge of the expected orientation of the reinforcing particles. Numerous models try to predict the orientation of particles in polymer suspensions. However, the interaction coefficient strongly depends on the aspect ratio of the particles and a prediction of the orientation behavior of additive mixtures with differently shaped particles has not been validated using conventional methods. In this work, the orientation of differently shaped particle mixtures in polymer suspensions is investigated for different fluid channel geometries. Finally, the Folgar–Tucker model is applied to filler mixtures and implemented into OpenFOAM®, which enables the comparison of filler orientation in different fluid channel geometries. Regarding the experiments a characteristic increase of the interaction coefficient was observed at a filling level of 5%. Furthermore, it was shown that a balanced mixing ratio yields higher interaction coefficients. With regard to the performed simulations, it was possible to show qualitatively how a considered interaction between fibers and platelets affects the orientations.
Dates on Literary Ostraca: A Case Study
Authors: Jurjens Judith
Published: June 2021

This paper presents an analysis of the dates found on ostraca containing the literary composition The Teaching of Khety, also known as The Satire of the Trades. Various aspects of these dates are discussed, for example the palaeography and the placement of the dates on the ostracon, for the purpose of outlining some scribal practices in ancient Egypt. From the dates themselves can be deduced that scribes conducted their literary activities all year round, both during the working week and at the weekend. Finally, the presumed educational context of the ostraca is discussed. The high percentage of dates on ostraca with Khety, in comparison to other literary compositions, suggests Khety was the most popular text used in the training of scribes.
Autobiographische Textüberlieferung im Alten Reich anhand phraseologischer „Cluster“
Authors: Kloth Nicole
Published: June 2021

There exists a group of texts among the autobiographical inscriptions of the Old Kingdom that, due to their close phraseological relationship, must go back to a common source, and which can be described as “Saqqara group” according to their place of origin. It dates back to the turn from the 5th to the 6th dynasty. This group can now be extended by additional autobiographies and furthermore differentiated. The classical creation of a stemma cannot be used, but instead different significant text sequences, which are called “clusters” here, are examined. The texts of this autobiographical cluster, starting from Saqqara, find their prolongation at the beginning of the 6th dynasty in El-Hawawish and it can be observed that they are transferred from higher-ranking officials at the end of the Old Kingdom to lower-ranking officials in the First Intermediate Period.

Single crystals of a new samarium platinum indide have been synthesized in a high-frequency furnace under flowing argon atmosphere. The crystal structure of SmPt2In2 was determined from single-crystal X-ray data (R1 = 0.0416 for 1049 F values and 63 variables). It belongs to the CePt2In2 structure type with the following crystallographic parameters: P21/m, mP20, Z = 4, a = 10.0561(8), b = 4.4214(2), c = 10.1946(8) Å, β = 116.492(5)°, V = 405.68(5) Å3. Physical properties were studied and the crystal chemical discussion is supported by electronic structure calculations.
Friedrich Althoffs Berufungspraxis in der evangelischen Theologie. Hermann Cremer und Adolf Harnack als Protagonisten des „Systems Althoff“
Authors: Kampmann Claudia
Published: June 2021

The article deals with the so-called „System Althoff“, that is the network of advisers Friedrich Althoff, ministerial director of the Prussian ministry of cultural affairs, created and employed in order to administer the faculties of theology at Prussian universities. In addition to leading the process of decision making in the ministry itself, he recruited a number of theology professors from the two dominant Church parties to advise him on appointing new professors. Famously, he consulted the opponents Hermann Cremer, a “positive” biblicistic Systematic professor in Greifswald, and Adolf Harnack, a Ritschlian Church Historian in Berlin, but he also counted theologians like Friedrich Loofs and Martin Kähler among his advisers. The article’s main body focusses on Althoff’s correspondence with Cremer and Harnack in order to analyse the minister’s practice of administration in depth. In a second step the paper will relate the minister’s relationship with his two most prominent theological advisers to the wider „System Althoff“ in theology. Both parts serve to show that Althoff rationalized and professionalized the process of decision making in the ministry of cultural affairs by carefully considering different professorial advises in light of the current (church) political climate.

Authors: Marta Lazo Carmen , Gómez López Jacinto , Segura Anaya Ana , Ortiz Sobrino Miguel Ángel
Published: June 2021

La radio universitaria ha experimentado en las dos primeras décadas del siglo XXI un importante proceso de expansión y desarrollo en España. Este impulso se debe a la progresiva apertura de facultades y grados de comunicación en las universidades españolas, pero también el cambio tecnológico y las posibilidades que Internet y las nuevas propuestas que ofrece. En este trabajo analizamos el camino recorrido por las radios universitarias españolas en los últimos veinte años a través de cuatro aspectos fundamentales: las propias emisoras, su creación, desaparición o consolidación, el tipo de gestión y grado de participación en ellas de los alumnos, la programación que ofrecen y el uso de las redes sociales. Este análisis nos permitirá determinar cómo el uso de la radio en la educación universitaria se consolida como aspecto fundamental en la formación de futuros periodistas capaces de manejar no solo los recursos técnicos sino de hacerlo con criterio periodístico y responsabilidad.
The Love Story against Displacement
Authors: Hidalgo Leigh-Anna
Published: June 2021

Fotonovelas, or photo-based comics, are a form of popular visual culture with a long history within Latin America and US Latinx communities. In 2016, I was part of a cross-disciplinary team of scholars from University of California, Los Angeles, who partnered with the East LA Community Corporation (ELACC)—through an Urban Humanities Initiative funded by the Andrew W. Mellon Foundation. Based in Boyle Heights, ELACC is a community-driven development organization focused on building affordable housing for local residents and improving quality of life in the neighborhood. Given the lack of engagement of residents in large-scale development projects, ELACC urged us to develop an urban humanities pedagogical and political tool for a campaign promoting just transit-oriented development (TOD). Our team draws on the fotonovela medium in a community-driven TOD campaign due to its ability to bridge multiple epistemological and praxis divisions in urban struggles, community organizations, and marginalized communities. I present the resulting fotonovela and examine how it politicizes narratives that challenge current urban development processes.
What Does Archipelagic Thought Offer toward the Understanding of Latinx Identity?
Authors: Delgado Aldeide
Published: June 2021

Curated by Yelaine Rodriguez and edited by Tatiana Flores, this Dialogues stages a series of conversations around Afro-Latinx art through interventions by Afro-Latina cultural producers. Black Latinxs often feel excluded both from the framework of latinidad as well as from the designation “African American.” The essays address blackness in a US Latinx context, through discussion of curatorial approaches, biographical reflections, art historical inquiry, artistic projects, and museum-based activism. Recent conversations around Latinxs and Black Lives Matter reveal that in the popular imaginary, Latinx presupposes a Brown identity. In their contributions to “Afro-Latinx Art and Activism,” the authors argue for a more inclusive and nuanced understanding of Latinx that does not reproduce the racial attitudes of the Lusophone and Hispanophone countries of Latin America, nor the black-white binary of the United States. They look forward to a time when the terms Afro or Black might cease to be necessary qualifiers of Latinx.

Published: June 2021

Ni-based catalysts supported on olivine were synthesized for cracking the biomass and producing the syngas. Syngas is used directly as fuel source for the cooling, heating, and power (CCHP) system, which can be produced through biomass pyrolysis process. Integrating combined CCHP systems with biomass pyrolysis results in a sustainable distributed energy system that effectively utilizes biomass resources and improves energy efficiency. To achieve a higher energy efficiency and more cost-effective operation, a simplified cost analysis method based on the Advanced System for Process Engineering (Aspen Plus) was applied to the CCHP system based on biomass pyrolysis. First, syngas was used as a fuel source for the CCHP system, which can be produced through a biomass pyrolysis experiment. In the experiment, the yields of the gas before and after the addition of a catalyst were compared. Second, syngas was passed to the reactor in Aspen Plus, which simulated the calorific values of the syngas produced by biomass pyrolysis under different conditions. Moreover, the simulated syngas heat values were applied to a TFRJ3K straw gas engine. Finally, the cost of the syngas for power generation, cooling, and heating was calculated. The power generation cost was 1.2 RMB/kW, the air conditioning refrigeration cost was 22.752 RMB/d, and the household heating cost was 20 RMB/d.

Published: June 2021

Due to the increasing accumulation of wastes around the world, the demand for sustainable products is increasing. Paper is a commonly disposed of material that can pose problems even when it is recycled. The concept of using cardboard (CB) as a material for furniture production has been around for many years, but CB furniture does not last long. This study examined the feasibility of using post-consumer recycled paper to produce paper-based boards for furniture design. Cardboard (CB) and office paper (OP) were the main post-consumer materials that were used. The CB and OP were mixed with polylactic acid (PLA) and limestone. The boards were made at a temperature of 200 °C and pressed at a pressure of 3.5 N/mm2 using a single opening hydraulic press. The physical and mechanical properties were tested according to the European standards for wood-based panels. Tests that are critical for furniture parts, such as the modulus of rupture (MOR), the modulus of elasticity (MOE), the internal bond, the screw withdrawal resistance, the thickness swelling, and the water absorption were examined. The paperboard samples exceeded some of the requirements for the general use of boards for interior fitments (including furniture) for use in dry conditions (Type P2) and for non-load bearing boards for use in humid conditions (Type P3).
Improving carbon product yields in biocarbon production by combining pyrolysis and anaerobic digestion
Authors: van der Wijst Cornelis , Ghimire Nirmal , Bergland Wenche Hennie , Toven Kai , Bakke Rune , Eriksen Øyvind
Published: June 2021

Solid carbon is an important raw material in industrial processes. Most of the charcoal produced today is via conventional carbonization, which suffers from huge carbon losses due to system inefficiency. Intermediate pyrolysis is principally similar to conventional carbonization and produces biocarbon while capturing the off gasses; among these off gasses is aqueous condensate, which is difficult to utilize due to the high water content and low energy content. This fraction can contain up to 25% of the carbon from feedstock, so utilization of this fraction is important for good overall carbon balance. Anaerobic digestion can be a promising tool for utilizing the carbon in the aqueous condensate by converting it into biomethane. Here, birch and spruce wood were pyrolyzed and the biomethane potential for the aqueous condensates was tested. The mass and carbon balances of the pyrolysis products of birch and spruce at two pyrolysis temperatures were performed, and biocarbon carbon yields ranging from 42% to 54% were obtained. Anaerobic digestion of the aqueous phases collected from the pyrolysis process was performed, with carbon recovery yields between 44% and 59%. A total carbon recovery of 77.8% to 85.7% was obtained, and the primary carbon losses were identified.

Ceramic samples based on the microcrystalline powders (Cu1–хAgx)7GeSe5I (x = 0, 0.25, 0.5, 0.75, 1) were prepared by pressing them at the pressure close to 400 MPa and subsequent annealing at 873 K for 36 hours. Using the microstructural analysis, the average size of microcrystallites of these samples was determined. Investigation of electrical conductivity of ceramics based on (Cu1 хAgx)7GeSe5I solid solutions was carried out using the method of impedance spectroscopy in the frequency range from 10 Hz to 3×105 Hz and within the temperature range 293...383 K. Analysis of the Nyquist plots allowed determining the contributions of ionic and electronic components to the total electrical conductivity. The temperature dependence of ionic and electronic conductivity in Arrhenius coordinates is linear, which indicates their thermoactivation character. The compositional behaviour of ionic and electronic conductivity, as well as their activation energies have been studied. Their nonlinear character can be explained by the complex process of recrystallization and Cu+ ↔ Ag+ cation substitution within the cationic sublattice.

In this work, two methods for fabrication of composite conductive films, consisting of single walled carbon nanotubes (SWCNTs) and PEDOT:PSS, in order to obtain films with high conductivity and transparency for their use in solar cell structures based on Si have been compared. The thickness and optical parameters of the films were determined using the spectro-ellipsometric measurements within the spectral range 0.6…5.0 eV. The electrophysical parameters were obtained from the four-point probe measurements. Our results showed that the method for deposition of SWCNTs and PEDOT:PSS in layers enables to obtain films with a much higher conductivity (220…306 S/cm) as compared to the method of applying a film from their mixture (6…209 S/cm).

The influence of two types of nano-impurities MF1 and MF2 on the dielectric properties of Shell oil transformer oil at the temperature 293 K has been studied. It has been shown that these magnetic impurities have no significant effect on the dielectric permittivity value of Shell oil, but more significantly increase its conductivity, in so doing, the impurity MF1 increases the conductivity of transformer oil 4 times larger than the impurity MF2. It has been ascertained that the low-frequency dielectric relaxation appearing in the studied samples can be described by the Cole–Cole equation. The parameters of this relaxation process and the influence of different types of magnetic impurities on them have been estimated.

A new approach to modeling the parameters of high efficiency textured silicon solar cells (SCs) has been presented. Unlike conventional optimization formalisms, our approach additionally includes such important factors as the non-radiative Auger recombination of excitons via deep impurity levels as well as electron-hole pairs recombination in the space charge region. A simple phenomenological expression offered by us earlier for the external quantum efficiency of the textured silicon solar cells with account of the photocurrent in the long-wave part of the absorption spectrum has been also used. Applying this approach, the key parameters of textured silicon SCs, namely: short-circuit current, open-circuit voltage and photoconversion efficiency, have been theoretically determined. The proposed formalism allows calculating the thickness dependence of photoconversion efficiency, which is in good agreement with the experimental results obtained for the heterojunction SCs with the record photoconversion efficiency of 26.6%. The offered approach and the results of applying this phenomenological expression for the external quantum efficiency of the photocurrent in the long-wave part of the absorption spectrum can be used to optimize the characteristics of high efficiency textured SCs based on monocrystalline silicon.

Published: June 2021

Bacteriological cultures from cerebrospinal fluids (CSF) have less sensitivity and specificity compared to quantitative PCR (RT-PCR), and multiple facts still conduct to the increase of negative culture. The aims of this study are to determine the molecular epidemiology and the simultaneous detection of bacterial meningitis in Morocco by using RT-PCR and compared this molecular approach with culture method to improve the etiological diagnosis of meningitis. The CSFs were collected over one-year period in 2018 in different hospitals covering all regions of the Kingdom of Morocco, from patients with suspected meningitis. The results showed the confirmation rate per culture recorded a rate of 33% and the RT-PCR of 70%. Molecular epidemiology is predominant of Neisseria meningitidis followed by Streptococcus pneumoniae and a dramatic reduction in meningitis due to Haemophilus influenzae following the introduction of conjugate vaccine in 2007. Also, the epidemiological profile shows a sex ratio M/F of 1.4 and a median age of 2 years. The national distribution showed a predominant of meningococcal disease followed by pneumococcal disease, especially a dominance of N. meningitidis over S. pneumoniae in two regions and a slight predominance of S. pneumoniae in the other two regions over N. meningitidis. Our research shows that culture in our country has less sensitivity and specificity than RT-PCR in diagnosis of bacterial meningitis and that molecular biology technique at bacteriology laboratories is desirable for diagnosis, early management of meningitis cases and in the context of the surveillance of meningitis in Morocco in parallel with culture.
Imaging, understanding, and control of nanoscale materials transformations
Authors: Zheng Haimei
Published: June 2021

The development of liquid cells for transmission electron microscopy has enabled breakthroughs in our ability to follow nanoscale structural, morphological, or chemical changes during materials growth and applications. Time-resolved high-resolution imaging and chemical analysis through liquids opened the opportunity to capture nanoscale dynamic processes of materials, including reaction intermediates and the transformation pathways. In this article, a series of work is highlighted with topics ranging from liquid cell developments to in situ studies of nanocrystal growth and transformations, dendrite formation, and suppression of lithium dendrites through in situ characterization of the solid–electrolyte interphase chemistry. The understanding garnered is expected to accelerate the discovery of novel materials for applications in energy storage, catalysis, sensors, and other functional devices.

Results of holter monitoring in patients with coronary heart disease depending on the severity of atherosclerotic lesions of the coronary arteries
Authors: Pylova Tetiana
Published: June 2021

The aim – to conduct a comparative analysis of the presence, frequency and duration of episodes of myocardial ischemia and arrhythmias based on the results of Holter monitoring in patients with coronary heart disease depending on the condition of the coronary arteries.

Materials and methods. We examined 53 patients (group I) with stable coronary heart disease (CHD) and slightly altered coronary arteries (INOCA), who were hospitalized in the period from October 2018 to February 2021 at the “City Clinical Hospital № 8” of Kharkiv City Council. Group II included 52 patients with a diagnosis of stable coronary heart disease, and according to coronary angiography (CAG) had stenosis of coronary arteries (CA) more than 50 %.

Results. According to the results of comparative analysis, it was found that in group I there were signs of myocardial ischemia – depression of the ST segment in 62.3 % (n=33) and elevation of the ST segment in 11.3 % (n=6), compared with group II -73 % (n=38) and 5.66 % (n=3), respectively. Ventricular arrhythmias (VA) have been reported in 52 patients of group I, and in 44 patients of group II. VA 4 and 5 type according to Laun, was significantly higher in group II compared with group I (p=0.0324). The occurrence of ventricular tachycardia was recorded in 5.7 % (n=3) of patients in group I and 9.3 % (n=5) patients of group II (p=0.347). In group II, there was a tendency to more episodes of ischemia compared with group I (p=0.072). The duration of ischemia was significantly longer in group I, compared with group II (p=0.042).

Conclusions. The results of the study did not show significant differences in the development of the number of episodes of myocardial ischemia according to Holter monitoring depending on the condition of the coronary arteries. The duration of episodes of ischemia in patients with INOCA is significantly longer than in patients with obstructive atherosclerosis. In patients with coronary heart disease with obstructive coronary arteries, ventricular arrhythmia was statistically significantly more severe according to Lown
O Processo de emancipação da mulher a partir das teorias de Simone de Beauvoir: um enfoque feminista do conceito de transcendência
Authors: Pedrosa Tom Menezes
Published: June 2021

Este artigo pretende explorar a questão da autoafirmação da subjetividade das mulheres por meio da transcendência, conceito central na obra O Segundo Sexo, de Simone de Beauvoir. Neste sentido, far-se-á um minucioso estudo da utilização do conceito de transcendência, sob a ótica existencialista, porém seguindo o enfoque feminista dado por Beauvoir, a fim de reconstruir a condição de opressão da mulher e os meios de superá-la.

Conhecimento, paixão e condenação a trajetória filosófica de Sócrates pelo olhar cinematográfico de Roberto Rossellini.
Authors: Silva Thais Conconi
Published: June 2021

Neste artigo buscamos contextualizar o cinema como forma de estudo da história e fonte de conhecimento. Uma vez que esta linguagem pode condensar diversas visões acerca de um fenômeno, ela se apresentará como meio para o desenvolvimento de uma postura crítica e reflexiva sobre a relação cinema e história, bem como os objetos que permeiam este discurso. Analisaremos o filme Sócrates (1972) da coleção Os Filósofos, dirigida por Roberto Rossellini, buscando, através do olhar cinematográfico, reconstruir a história do filósofo e a evolução de seus pensamentos, numa perspectiva filosófica. Rossellini focaliza o caminho de Sócrates até a sua morte por cicuta, ilustrando a fidelidade do filósofo à sua própria consciência. É mostrado com certo rigor histórico conflitos e guerras, as nuances do politeísmo grego, o espírito questionador da filosofia antiga e o julgamento de Sócrates perante a Assembleia. O artigo analisa, de forma intertextual, as principais obras de Sócrates e aquelas que seus discípulos escreveram sobre ele como a Defesa de Sócrates, por Platão e os Ditos e feitos memoráveis de Sócrates, por Xenofonte. Incluímos, também, observações advindas de artigos científicos que versam sobre as experiências do filósofo e reflexões filosóficas realizadas por este. A análise fílmica foi feita com base nas transcrições de diálogos, imagens, luz e banda sonora, refletindo sobre conceitos de filosofia e religião presentes na obra. Pretendemos mostrar que o uso do cinema explorado criticamente de forma ampliada, ou seja, através dos símbolos e signos que estruturam uma base de valores estéticos e éticos em algum contexto temático e cultural, pode potencializar a construção de novos saberes e reflexões.

Background.The prevalence of various allergic diseases has increased worldwide in recent decades. Allergy diagnosis in children should be economically optimal and as sparing as possible, while ensuring the high quality of medical care.Objective.The aim of the study is to develop optimal algorithms for analysis of sensitization profile in children with allergy family history, or suspected allergy, or atopy phenotype.Methods.Complete examination of 153 children aged from 1 to 17 years 11 months was performed. Children were divided in 4 groups according to the presence and characteristics of complaints, the presence of allergic disease. Sensitization was determined via the “gold standard” of allergy diagnosis — the ImmunoCap method (Phadia, Sweden), and the results of skin testing.Results.97 (63.4%) children have shown sensitization to various allergens. We have revealed seasonal manifestation of allergy in children to various allergens: Fagales in 89-92% of cases, grasses in 68-72% of cases, weeds in 39-57% of cases. Complaints of all-year manifestations of allergic rhinitis were revealed in 24% of cases to cat dandruff, complaints of coughing and/or bronchospasm — in 100% of cases to birch pollen and in 35% of cases to house dust. The sensitization analysis has revealed strong correlations with confirmed statistical significance between pollen allergen sensitization classes in groups of different plants.Conclusion.Optimal algorithms for sensitization diagnosis in children living in Moscow agglomeration were developed according to the obtained results and revealed correlations.

ABSTRACT Objective: Understand the continuity of stimulation of neuro-psychomotor development in children with congenital Zika syndrome. Method: Descriptive-exploratory study with theoretical support in symbolic interactionism. Between August and November 2019, 12 health professionals were interviewed in depth; and to the focus group, seven caregivers of children with the syndrome. The analysis was thematic inductive. Results: The continuation of neuro-psychomotor stimulation of children with Zika syndrome goes through: organizational difficulties (lack of doctors, professional unpreparedness, dissatisfaction and search for other services); socioenvironmental aspects (low maternal education, low socioeconomic level, difficulty in moving and lack of support); and conditions inherent to children (hospitalizations for respiratory crises, seizures, hypoactivity and social stigma). Final considerations: A strengthened support network with qualified human resources is necessary in order to provide comprehensive care and avoid the discontinuity of neuro-psychomotor stimulation of children with congenital Zika syndrome.

ABSTRACT Background: tissue expanders have high relevance in plastic surgery and among indications it is worth mentioning their use in the treatment of burn reconstruction. Although it shows good results, its use requires special care because some complications can interrupt the reconstruction process. The objective of this study was to report the experience of the Clinics Hospital (University of Sao Paulo) with the use of tissue expanders to treat burn sequelae, establishing the incidence of complications, and identifying risk factors for their occurrence. Methods: a retrospective, observational, and analytical study, evaluating the use of expanders in burns sequelae treatment from 2009 to 2018. Results: 245 expanders were placed in 84 patients, 215 were female, with a mean age of 19.96 years, being 40% in the trunk and 20% in the scalp, with a predominance of rectangular shape in 76.7% of cases. Complications were classified as major and minor.Complications occurred in 17.95% of cases, and extrusion and infection were the most common. There was a higher incidence of complications in expanders used in the upper and lower limbs as well as in those who did not undergo concomitant expansion (p <0.05), with an even higher chance of major complications in patients submitted to additional expansion. From 2009 to 2018, we observed a decrease in the incidence of complications. Conclusion: the complication rate (17.95%) is similar to other studies of the literature, there was a higher rate of complication with expanders placed in the limbs and a higher rate of major complications when additional expansion was done.

ABSTRACT: Macronutrient suppression is one way to identify which chemical elements is the most important in the early development of seedlings of forest species. This study evaluated the initial growth of Eucalyptus benthamii seedlings through morphological and physiological variables, submitted to doses of N, P and K, and liming. The experimental design to install the experiment was completely randomized, with a 2x9 factorial scheme, in which levels of factor “A” referred to absence and presence of liming and levels of factor “B”, to the different treatments of NPK. Morphological variables of SD (stem diameter) and H (height) and the physiological variables of A (photosynthesis), E (transpiration), gs (stomatal conductance), Ci/Ca (relationship between intercellular and atmospheric CO2 concentration) and WUE (water use efficiency) were measured. For morphological variables, the absence of N directly affected the means and there was a direct relationship between increase of the dose and increase of SD and H. There was a positive relationship of P mainly in relation to shoot dry matter content (SDMC) and root dry matter content (RDMC). For the physiological variables, there was no direct response with the doses of N or P, with K being the element that most influenced the variables, especially when limestone was applied, resulting in higher averages for photosynthesis, transpiration and stomatal conductance. With the purpose of meeting the morphological and physiological demands, the recommendation for cultivation of Eucalyptus benthamii under the conditions of this study is the doses 150-200-150, without liming application.

ABSTRACT: Knowledge on weed biology and ecology is fundamental to provide suitable control practices in weed management systems. The objective of this research was to understand the effect of light and temperature on germination of Chamaesyce hirta, as well as to evaluate the effect of depth of seed placement in the soil in the emergence of the plant. Two experiments were conducted. In the first one, in the laboratory, the seeds were placed to germinate in plastic boxes and kept in a B.O.D. germination chamber, under constant temperatures of 20, 25, 30 and 35 ºC, either in the dark or under continuous light. Daily germination assessments were performed. The percentage of germinated seeds in the 10-day period and the germination speed index (GSI) were calculated. In the second trial, carried out in greenhouse conditions, 100 seeds were planted, under six levels of seeding depth (0, 1, 2, 3, 4 and 5 cm) and three soil cover conditions: no straw, under black oats (Avena strigosa) straw and under corn (Zea mays) straw. Daily plant emergence was counted along 30 days and total emergence and GSI were calculated. Germination of C. hirta seeds occurs both in the presence and absence of light. For the highest temperature, both increased germination and GSI were reported in the presence of light. The highest levels of emergence were obtained with the absence of plant cover and under corn straw at 0 cm depth. The presence of black oat straw on the soil reduced the emergence of C. hirta.

Published: June 2021

Abstract Vulnerability processes and effects, albeit of great importance to cohesion and territorial policies, are nonetheless still underexplored and narrowly operationalized in scientific research. In particular, most assessments rely on economic indicators and a limited territorial scale, which do not have the same analytic potential of a broader view at a national level with regional/municipal similarities, specificities, and inter-connections. This gap also applies to health-related vulnerabilities, which, stemming from a lack of socioeconomic and environmental resources, has increased during and after the economic crisis of the past decade. This paper aims to analyze the health vulnerability phenomena in Portugal from a spatial perspective. Following a Multiple Correspondence Analysis, different territorial profiles of social vulnerability associated with the population health condition and access to and use of “health services” are identified. We conclude by outlining the importance of adding the spatial context to health policies addressing vulnerabilities and suggest avenues for future research.
Accessibility to primary health care in low-density regions. A case study: NUTS III - Baixo Alentejo - Portugal

Published: June 2021

Abstract This study diagnosed the situation regarding the physical accessibility of the resident population to primary health care, based on the characteristics of the population served, their spatial distribution in the territory, based on space-time analysis. Thus, bearing the different means of transport available and the specific features of a low-density territory, we considered several mobility profiles under analysis, and selected the Baixo Alentejo as the study area. In methodological terms, besides using the location of primary health facilities and their areas of influence, the use of the road network and its restrictions, we selected the use the new 1x1 km grid, recently implemented throughout the EU (European Union), instead of using the statistical units or administrative boundaries. Its advantages allow overcoming some of the issues of the usual base cartography. The final results can be divided into two groups: conclusions related to the methodologies used and conclusions related to the accessibility of primary health care equipment in the study area.
