European Multi-Level Governance
Authors: Bran Florina , Bodislav Dumitru Alexandru , Rădulescu Carmen Valentina
Published: December 2019

This paper represents an overview of the concept of multi-level governance and the approach delivered on innovation at European level with the purpose of helping and empowering researchers and businesses to thrive in a technologically advanced economy. The concept of multi-level governance derives from the analysis of the institutional framework for the development of Community policies and the Community political process. This stems from the presumption that the Community governance system has a high degree of differentiation and integration both vertically and horizontally. The multi-level governance model illustrates how certain competences of the national state are transferred to the supranational level or to the public or private sub-national authorities. Within this model, we can meet both supranational actors and actors at national, regional or local levels. This type of governance is characterized by the existence of a limited number of authorities, divided so as to be able to perform more functions, excluding their overlapping to exercise exclusively competences on delimited territories. Multi-level governance in innovation is characterized by a national transition as a unique place for the development and implementation of innovation policy, both at supranational and sub-national levels. Keyword: multi-level governance, European Union, development, social cohesion, institutions

Published: December 2019

Recently, many articles deal with Internet and mobile phones that have penetrated all sectors of the economy, including agriculture, in the light of their benefits. Various reports, including the World Bank, describe the main benefits of new information and communication technologies and promote their greater integration into the wider economy to increase efficiency by completing other production factors and fostering innovation, for example, drastically reducing transaction costs. The article analyzes recent literature but also presents novelty elements that emerged from questions such as the risks associated with new technologies considering that there are not enough studies in the field confirming, on the one hand, the benefits but also the losses caused by them. Keyword: New technology, agriculture, innovation
Shaping the Common Labor Market between Denmark and Sweden: Lessons for Sustainable Development
Authors: Plaskonis Kate
Published: December 2019

Though Denmark and Sweden have had a similar historical development over the years, the differences in their labor markets have become more visible than ever. While the labor shortage is increasing in Copenhagen, there is a high number of unemployed individuals with a more substantial proportion of vulnerable groups among them in Sweden. Despite some appealing factors (such as less governed labor law, the simplicity of employing and the high wages), the interest of Swedes to work in Copenhagen area has decreased, and as a result, the number of commuters has fallen. Could it then be employers’ attitudes towards foreign-born individuals that differ? Through interviewing Swedish and Danish employers and foreign-born population, Fördomsfönster Öresund project investigates if the attitudes differ and how social sustainability and utilizing the existent competence frame a common regional labor market. Interviews show that some concepts might be crucial in addressing the issue: language, prejudice, leadership and the difference in perceptions. By informing and responding to these problem areas, there is a strong possibility of greater integration, competence-based employment and higher revenues in commuting within the region. Keywords: Diversity, competence, social sustainability, labor market, green commuting
Education in Biosphere Reserves to Enhance Intercultural Competence between Japanese and Russian Youth
Authors: Mammadova Aida
Published: December 2019

Japan and Russian youth has many stereotypical cultural perceptions about each other’s culture, which in many times leads to cultural misunderstandings with negative effects. In this study we decided to use Biosphere Reserves (BRs), which are highly recognized areas under UNESCO’s MAB Programme for their conservation, learning and sustainable development initiatives, to enhance the cultural competence and awareness in youth of both countries. 50 Japanese students were divided into two groups and visited 3 Russian BR with 4 universities, with 2 weeks’ duration of each trip. Later 14 Russian students visited Japanese Mount Hakusan BR and participated in the academic BR training course for 3-weeks. We have conducted the specific survey to evaluate the changes in students’ knowledge, attitude and skills towards each other’s culture, and it was observed that all 3 elements were increased in all students. Besides 90% of students replied that they were strongly agree, that BR helped them to understand cultural diversity of each county. 87% replied that community interaction was the most effective way to break cultural stereotypes. This kind of cross-cultural communication in BR, showed very positive results and can be used as the new methodology for the future environmental education. Keywords: Environmental Education, Sustainability, Biosphere Reserves, Cultural Competence, Awareness
Use of Industrial Waste to Produce Ceramic Coatings on Metal
Authors: Pereira Antunes Maria Lucia , Souza C.S. , Moraes R.F. , Rangel E.C. , Cruz N.C.
Published: December 2019

Industrial processes are activities that produce large amounts of wastes. Often these wastes are disposed in dam or landfills, occupying large areas and causing environmental damage such as the contamination of water and soil. According to the Circular Economy concept, waste should be minimized and reused as raw material in a new process. This work describes two residues, namely red mud (bauxite residue) and waste foundry sand (WFS), whose chemical compositions indicate their suitability for use as protective coatings. These residues were used to obtain coatings on aluminum alloy by employing plasma electrolytic oxidation (PEO). The PEO process enables the creation of coatings that are durable, uniform, and strongly adherent on metallic components of different shapes. The mineralogical compositions of the coatings were investigated using X-ray diffraction (XRD). Surface wettability was determined by contact angle measurements and evaluation was made of the average surface roughness. Alumina was the main phase observed by XR, indicating good chemical stability and high thermal resistance. The coatings obtained with the red mud were thicker and less rough, compared to those obtained with the WFS. The results demonstrated the feasibility of using these wastes for coating metals in order to improve their properties and enable new applications. Keywords: Industrial Waste, Red Mud, Waste Foundry Sand, Circular Economy, Ceramic Coating.

Use of phosphites in postharvest to control anthracnose of yellow passionfruit
Authors: Dutra Jaqueline Barbosa , Blum Luiz Eduardo Bassay
Published: December 2019

Brazil is the largest producer of yellow passionfruit (Passiflora edulis f. flavicarpa) and one of its production problems is the anthracnose (Colletotrichum spp.). The use of fungicides on control of postharvest diseases is a method that protects the fruits during storage. However, precautions must be taken due to fungicide toxicity. The restriction to the use of fungicides in post-harvest led a demand for alternative methods of disease control, and, the phosphite application is one of these methods. Therefore, this work aimed to evaluate the effects of fruit immersion in phosphite on postharvest control of anthracnose. Two tests were developed in vitro to assess the effect on the fungus: phosphite Mg2 (40%P2O5+6%Mg), Zn (40%P2O5+10%Zn), Ca1 (30%P2O5+7%Ca) and K1 (40%P2O5+20%K2O). For the in vivo tests, passionfruit (Gigante Amarelo), were wounded and inoculated (50mL; 106conidia mL-1). Two tests were done with: Cu (25%P2O5+5%Cu), 2.5mL L-1; Zn, 2.5mL L-1; K1, 2.5mL L-1; Mg1 (30%P2O5+4%Mg), 3mL L-1; Ca1, 3mL L-1; Ca2 (10%P2O5+6%Ca), 4mL L-1; K2 (40%P2O5+20%K2O), 1.5mL L-1; Mg2 (40%P2O5+6%Mg), 1.5mL L-1; K3 (20%P2O5+20%K2O) 1.75 mL L-1; K4 (30%P2O5+20%K2O), 1.75mL L-1. Other two tests with phosphites Mg2, Ca1, Zn and K1 were with CaCl2 (2%) was developed. In addition, phosphites were tested at 25, 50, 100 and 200% of the dose: K2 (100%; 1.5mL L-1) and Ca1 (100%; 3 mL L-1). The phosphites Mg2, Ca1, K1 and Zn in vitro have reduced mycelial growth and fungus conidia production. The phosphites K1, K2, Ca1 and Zn were the ones that most reduced the size of the anthracnose lesion. There were no differences among treatments, concerning the physico-chemical fruit properties analyzed (% fresh mass loss, total soluble solids, pH and titratable acidity).

Vaccines or immunobiologicals have antigenic properties and, in public health, are considered an important strategy in the prevention and control of immuno-preventable diseases. The objective of this study was to carry out review of the nursing staff's role in vaccine care. This is a scoping review, conducted in first semester of 2017, with data collected in 17 national and international databases. To guide the evaluation of the selected materials, an instrument composed of some collection indicators was used. The final sample consisted of eight publications. The data was inserted into the Microsoft Excel 2010 Program, and analyzed in a descriptive way. The identification of a variety of actions of the nursing team in the care with vaccines was verified and grouped in: vaccine room; behavior in the vaccine room; refrigerator care; organization of vaccines inside the refrigerator; monitoring and register of changes in temperature; measures adopted with vaccines under suspect; behaviors regarding vaccines in thermal boxes; professional knowledge in the vaccine room and other important behaviors. Given this evidence, it is essential to detect factors that may compromise the quality and conservation of vaccines. For this, it is understood the need for training aimed at the professionals involved in the immunization and the importance of supervision activities in the vaccine room by the nurse.

Published: December 2019

The objective of this work was to evaluate the effects of various Si sources currently used in studies of Si doses in nutrient solutions on dry matter yield and the accumulation of nutrients and Si in rice plants. Treatments of rice plants with three sources of Si (monossilicic acid, sodium metasilicate, potassium metasilicate) and a treatment without Si were allocated in a randomized block design with ten replications. After 39 days in the nutrient solution, the following traits were evaluated: leaf area, leaf specific mass, dry matter yield of roots and shoots, and levels of K, Na, and Si in leaves and roots. Si increased leaf area, leaf specific mass, and dry matter yield of shoots and roots regardless of the Si source. Levels of Si in leaves and roots were significantly higher in relation to the control treatment but no significant difference among Si sources was identified. It was also observed that K and Na were adequately balanced across the treatments. Thus, a cheaper and easier to obtain Si source, such as sodium metasilicate and potassium metasilicate, may be chosen to carry out studies of Si additions to nutrient solutions.

Knowledge of factors related to the dynamics of herbicides in the environment is of fundamental importance to predicting the behavior of herbicides in soils with different attributes, to select appropriate dosages, as well as to avoid harmful effects on the environment and subsequent crops. The objective of this work was to evaluate the sorption and desorption of ametryn in seven soils with different attributes. Initially, the equilibrium time was determined by the "Batch Equilibrium". Then, it was performed the sorption test with different concentrations (0.5; 1; 2; 4; 8; 16; 24 and 32 mg L-1) of ametryn in 0.01 mol L-1 CaCl2. 10 mL of these solutions were added to samples of 2.00 g of each soil, remaining under rotary shaking for 4 hours. After centrifugation and filtration, the ametryn concentration in the supernatant was determined by high-performance liquid chromatography. Desorption was evaluated using the tubes containing 16 mg L-1 prior to sorption testing. The results indicated that the sorption and desorption of ametryn depend on the physicochemical attributes of the soil. Sorption was higher in soils with high organic matter content and high ion exchange capacity, while desorption was inversely proportional to sorption.

Bloomberg insists that we need to get our priorities straight: the economy comes before the earth, capitalism before nature. Yet, from any sort of realistic, world-wise perspective, it is clear that we are faced with two immense, imminent, and irreversible crises, one threatening within as short a time as a year to destabilize the world capitalist economy, the other promising to destroy the planet as a home to humanity, destabilizing industrial civilization and undermining the survival chances of hundreds of millions or even billions of people this century. Both represent the culmination of capitalist contradictions over centuries of development and both point to the need to transform society in revolutionary ways. It is the coevolution of economic and ecological contradictions under global monopoly-finance capital that defines the epochal historical crisis of our times. In this new issue of Monthly Review, we also celebrate Monthly Review's relationship with the annual School of Ecology in Mauritius.
Capitalism and Robbery
Authors: Foster John Bellamy , Clark Brett , Holleman Hannah
Published: December 2019

Historical capitalism cannot be understood aside from its existence as a colonial/imperialist world system in which the violent exercise of power is an ever-present reality. In order to uncover the material conditions governing concrete capitalism, including its interface with land, nonwage labor, and corporeal life, it is therefore necessary to go beyond the inner reality of exploitation, and address expropriation, or the process of appropriation without equivalent (or without reciprocity) through which capital has sought to determine its wider parameters.
From Mass Incarceration to Mass Coercion
Authors: Jay Mark
Published: December 2019

From the mid-1960s to the late 2000s, the number of people locked in U.S. prisons and jails, and forced onto parole or probation, increased from less than eight hundred thousand to more than seven million. From the beginning, this explosive growth, known commonly as mass incarceration, has been about containing, stigmatizing, and exploiting the poorest sectors of the working class. While an important prison reform movement has been underway for many years, private forces have attempted to co-opt this movement and have implemented and profited from alternative forms of mass coercion proliferating throughout society.

Letrillas del alba
Authors: Hernández Rodríguez Daniel Arturo
Published: December 2019

Antes de comenzar voy a leer un poema del escritor francés Pascal Quignard, de un libro que desafortunadamente no parece estar traducido, así que tendrán que soportar las deficiencias de mi versión al castellano. El poema lleva por título “La bestia acorralada que está en el fondo del arte” y tiene que ver con la emergencia del ser humano, de la palabra, del arte… y de la infancia, desde una perspectiva que puede ser, en cierta forma, sorprendente. El nombre de libro, Tondo, está inspirado en una serie de pinturas en formato circular, des tondi, de Pierre Skira. Dice Quignard al comienzo de su libro que Salomé lleva en ese “plato redondo, ese disco, ese tondo” la cabeza del bautista. En esas pinturas redondas de fondo muy oscuro, reproducidas en el libro, lo que se distingue, como si fueran los restos de un desastre violento, son pedazos de maderas y cuerdas de violines o cellos, pedazos de libros viejos y desvencijados, y calaveras, aunque en algunos parezca asomarse algo distinto en virtud de la composición.

Published: December 2019

Background

Simultaneous measurement of 25(OH)D and 24,25(OH)2D is a new tool for predicting vitamin D deficiency and allows evaluating CYP24A1 lack of function. Interpretation of 24,25(OH)2D should be performed according to 25(OH)D levels and a ratio, called the vitamin D metabolite ratio (VMR) has been proposed for such a purpose. Unfortunately, the VMR can be expressed in different ways and cannot be used if 24,25(OH)2D concentrations are undetectable. Here, we propose evaluating the enzyme activity taking into consideration the probability that a normal population presents undetectable 24,25(OH)2D concentrations according to 25(OH)D levels. We thus retrospectively measured 25(OH)D and 24,25(OH)2D in a population of 1200 young subjects to evaluate the 25(OH)D threshold above which the enzyme was induced.

Methods

Serum samples from 1200 infants, children, adolescent and young adults were used to simultaneously quantify 25(OH)D and 24,25(OH)2D by LCMS/MS.

Results

Median (interquartile range [IQR]) levels were 20.6 (14.4–27.2) ng/mL for 25(OH)D. 172 subjects (14.3%) presented 24,25(OH)2D values below the LOQ. When 25(OH)D values were <11 ng/mL, 63.1% of subjects presented undetectable 24,25(OH)2D concentrations. Percentage decreased with increasing 25(OH)D values to become 19.7% for 25(OH)D comprised between 12 and 15 ng/mL, 5.1% for 25(OH)D between 16 and 20 and 0.7% for 25(OH)D >21 ng/mL.

Conclusions

We suggest using a statistical approach to evaluate CYP24A1 function according to 25(OH)D concentrations. Our results also show that vitamin D deficiency, as defined biochemically, could be around 20 ng/mL in infants, children, adolescent and young adults and that vitamin D deficiency could be evaluated on a more individual basis.

Bioconvection in the Rheology of Magnetized Couple Stress Nanofluid Featuring Activation Energy and Wu’s Slip
Authors: Khan Sami Ullah , Waqas H. , Bhatti M. M. , Imran M.
Published: December 2019

In order to meet the current challenges in the fabrication of nanobiomaterials and enhancement of thermal extrusion systems, current theoretical continuation is targeted at the rheology of couple stress nanofluid by exploiting activation energy, porous media, thermal radiation, gyrotactic micro-organisms, and convective Nield boundary conditions. The heat and mass performances of nanofluid are captured with an evaluation of the famous Buongiorno model, which enables us to determine the attractive features of Brownian motion and thermophoretic diffusion. The couple stress fluid is beneficial to examine multiple kinds of physical problems because this fluid model has the capability to describe the rheology of various complex fluids, e. g., fluids having long-chain molecules as a polymeric suspension, liquid crystals, lubricants, and human and animal blood. Simultaneous behavior of the magnetic field and porosity are studied with thermal radiation effects. The distribution of velocity has been conducted by using second-order velocity slip (Wu’s slip) and activation energy features. For the dimensionless purpose, the similarity variable has been initiated, and the modeled equations are renovated sufficiently. A famous shooting method is used to determine the numerical solutions, and accurate results have been obtained. A variety of critical flow parameters is graphically illustrated with physical significance.
Analysis of Risk Factors for Underground Coal Gasification
Authors: Škvareková Erika , Tomašková Marianna , Wittenberger Gabriel , Zelenák Štefan
Published: December 2019

The purpose of this article is to determine the environmental impacts of underground gasification on the population and to analyze the risk of underground coal gasification (UCG) activities using selected risk assessment methods. Coal gas is a regular part of coal deposits and its extraction also allows the use of coal deposits that cannot be extracted by traditional methods. These technologies bring both positive and negative aspects. The paper points out the risk analysis, hazard identification and assessment during the operation of UCG technology using a risk graph and a risk matrix. Identified risks to workers that cannot be reduced should be taken into consideration and appropriate safeguard should be used. For each risk, it is necessary to inform employees about regular education and training. From worldwide experience with this technology, it is possible to analyze risks in Slovakia. Actual gasification produces polluting gases such as carbon dioxide, carbon monoxide, hydrogen sulphide, hydrogen sulphide, nitrogen oxides, tar and ash, and creates a risk that may occur on and under the surface of the site depending on the geological and hydrogeological structure of the deposits. Possible measures to mitigate the adverse effects are proposed for the implementation of this technology. Coal is still one of the main domestic primary energy sources. Currently, only 5 out of 19 deposits in the Slovak Republic are used. Underground gasification could increase the use of Slovak coal and brown coal deposits.

Published: December 2019

Forage nutritive value impacts animal nutrition, which underpins livestock productivity, reproduction and health. Genetic improvement for nutritive traits in perennial ryegrass has been limited, as they are typically expensive and time-consuming to measure through conventional methods. Genomic selection is appropriate for such complex and expensive traits, enabling cost-effective prediction of breeding values using genome-wide markers. The aims of the present study were to assess the potential of genomic selection for a range of nutritive traits in a multi-population training set, and to quantify contributions of family, location and family-by-location variance components to trait variation and heritability for nutritive traits. The training set consisted of a total of 517 half-sibling (half-sib) families, from five advanced breeding populations, evaluated in two distinct New Zealand grazing environments. Autumn-harvested samples were analyzed for 18 nutritive traits and maternal parents of the half-sib families were genotyped using genotyping-by-sequencing. Significant (P < 0.05) family variance was detected for all nutritive traits and genomic heritability (h2g) was moderate to high (0.20 to 0.74). Family-by-location interactions were significant and particularly large for water soluble carbohydrate (WSC), crude fat, phosphorus (P) and crude protein. GBLUP, KGD-GBLUP and BayesCπ genomic prediction models displayed similar predictive ability, estimated by 10-fold cross validation, for all nutritive traits with values ranging from r = 0.16 to 0.45 using phenotypes from across two locations. High predictive ability was observed for the mineral traits sulfur (0.44), sodium (0.45) and magnesium (0.45) and the lowest values were observed for P (0.16), digestibility (0.22) and high molecular weight WSC (0.23). Predictive ability estimates for most nutritive traits were retained when marker number was reduced from one million to as few as 50,000. The moderate to high predictive abilities observed suggests implementation of genomic selection is feasible for most of the nutritive traits examined.

Published: November 2019

Introduction: fibrous dysplasia of bones is a non-hereditary congenital benign bone disorder, where normal bone is replaced by pseudofibrous tissue containing immature osteogenesis.Case report: a 29-year-old patient with chronic hemodialysis who had a swollen mouth and hard palate that had been evolving for a year, impeding chewing and swallowing and causing facial asymmetry. Cranio-facial CT revealed multiple osteolytic bone-blast lesions, the histopathological study of which favored polyostotic fibrous dysplasia.Discussion: fibrous dysplasia lesions may be single or multiple and may be responsible for pain and fragility, causing neurological complications in craniofacial localization. Imaging and, when a biopsy is needed, histology can establish the diagnosis. The treatment is based on bisphosphonates or, in special cases, surgical excision.

La mortalidad neonatal: un reto para el país y la universidad
Authors: Cárdenas Díaz Maximiliano , Franco Paredes Gustavo , Riega López Pedro
Published: December 2019

Los medios de comunicación tienen la capacidad para colocar en la agenda pública problemas de interés nacional y promover respuestas de los actores del gobierno y la sociedad civil. No obstante, muchas veces la noticia llega incompleta o sesgada, lo cual dificulta ver los problemas de forma integral y apropiada. La universidad tiene un rol clave que cumplir al respecto, en función a su solvencia técnica y científica, pero por sobre todo, de su legitimidad y credibilidad social. En ese contexto, la Facultad de Medicina de San Fernando de la Universidad Nacional Mayor de San Marcos organizó el conversatorio “Mortalidad neonatal: situación y propuestas desde la universidad”, llevado a cabo el 13 de setiembre de 2019, con la participación de autoridades políticas, expertos temáticos y representantes de la sociedad civil, cuyos comentarios se sintetizan en este editorial. Esta actividad se enmarca en el observatorio del sistema de salud del Perú, que dicha casa de estudios viene construyendo durante el presente año.

Published: December 2019

Introducción: La provincia constitucional del Callao es una de las más afectadas por la epidemia de tuberculosis a nivel nacional. Asimismo, se debe considerar que los establecimientos de salud del primer nivel de atención son usualmente la puerta de entrada para estos pacientes, al sistema sanitario. Objetivos: Describir las características de la oferta de servicios de salud en unidades de tuberculosis en el primer nivel de atención de la Provincia Constitucional del Callao. Métodos: Se realizó un estudio descriptivo, en 45 servicios de salud, en los que se indagó sobre características de infraestructura, recursos humanos y el ingreso de data al sistema de información. Resultados: Los 45 establecimientos contaban con “unidades de atención diferenciadas para tuberculosis”, atienden en ellas 19 médicos, 35 enfermeros, 3 nutricionistas, 10 psicólogos, 9 asistentes sociales y 50 técnicos de enfermerías. El 96% del personal realizó otras atenciones, y el 33% tuvo menos de 6 meses laborando en estas unidades. Solo un 40% recibió algún entrenamiento específico. El sistema de información fue manual, utilizando libros y registros físicos. Conclusiones: Los servicios de salud cuentan con infraestructura adecuada, pero existen serias limitaciones de personal y en el sistema de información.

Pulse Shape Influence on the Accuracy of Z-scan Measurements
Authors: Dement’ev A. , Jovaiša A.
Published: December 2019

Although the laser pulses with durations ranging from nanoseconds to femtoseconds and various pulse shapes are utilized for the Z-scan measurements, the influence of the temporal pulse shape on the measurement results is often neglected. In this paper, we tried to differentiate the influence of the temporal pulse shape on the common Z-scan technique with a small on-axis aperture in two cases: when the pulse peak intensity at the beam waist is known (for relatively long pulses), or when the total pulse energy and full width at half maximum (FWHM) of the correlation functions or FWHM of pulse durations are known (for short pulses).
Detecting and Locating a Changed Segment in a Binomial Sequence: Comparison
Authors: Zuokas D.
Published: December 2019

A class of tests for testing a changed segment in a binomial sequence is proposed and an asymptotic behavior is established. A consistent procedure of estimating the length of a changed segment is proposed. The performance of two tests from the given class is compared by Monte-Carlo simulations. The results are applied for the non-coding deoxyribonucleic acid (DNA) sequence analysis.
Dynamics Analysis and Limit Cycle in a Delayed Model for Tumor Growth with Quiescence
Authors: Yafia R.
Published: December 2019

The model analyzed in this paper is based on the unstructured model set forth by Gyllenberg and Webb (1989) without delay, which describes an interaction between the proliferating and quiescent cells tumor. In the present paper we consider the model with one delay and a unique positive equilibrium E∗ and the other is trivial. Their dynamics are studied in terms of the local stability of the two equilibrium points and of the description of the Hopf bifurcation at E∗ , that is proven to exists as the delay (taken as a parameter) crosses some critical value. We suggest to examine in laboratory experiments how to employ these results for containing tumor growth.
Mathematical Modelling of Hydromagnetic Convection from a Rotating Sphere with Impulsive Motion and Buoyancy Effects
Authors: Anwar Bég O. , Takhar H. S. , Nath G. , Chamkha A. J.
Published: December 2019

The convective heat transfer on a rotating sphere in the presence of magnetic field, buoyancy forces and impulsive motion is examined theoretically and numerically in this paper. We apply a boundary layer model comprising the balance equations for x and y direction translational momentum and heat transfer, and solve these coupled non-linear partial differential equations using Blottner’s finite-difference method [1]. The numerical solutions are benchmarked with the earlier study by Lee [2] on laminar boundary layer flow over rotating bodies in forced flow and found to be in excellent agreement. The effects of magnetic field, buoyancy parameter, Prandtl number and thermal conductivity parameter on translational velocities and temperature and other variables (shear stress etc) are presented graphically and discussed at length. The problem finds applications in chemical engineering technologies, aerodynamics and planetary astrophysics.
On the Discounted Penalty Function for Claims Having Mixed Exponential
Authors: Šiaulys J. , Kočetova J.
Published: December 2019

It is considered the classical risk model with mixed exponential claim sizes. Using known results it is obtained the explicit expression of the GerberShiu discounted penalty function ψ(x,δ) = E e −δT 1(T < ∞) , by some infinite series. Here δ > 0 is the force of interest, x – the initial reserve and T – ruin time. The dependance of the discounted penalty function on the main parameters x, θ, λ, δ, α, σ, ν is presented in diagrams, where λ > 0 is the parameter of Poisson process, θ > 0 is the safety loading coefficient, 0 ≤ α ≤ 1 and σ, ν > 0 are the parameters of the mixed exponential distribution

There is a global variation in the incidence of renal masses with the developed nations having a greater incidence. About 80–90% of renal malignancies are renal cell carcinomas (RCC) which account for 2–4% of all cancers. In Africa and the Middle East, the age-standardized incidence for RCC is 1.8–4.8/100,000 for males and 1.2–2.2/100,000 for females. The management of renal cell cancer is challenging. A multidisciplinary approach is effective for diagnosis, staging, and treatment. Guidelines recommend active surveillance, thermal ablation, partial nephrectomy, radical nephrectomy, cytoreductive nephrectomy and immunotherapy as various modalities for various stages of RCC. However, open radical nephrectomy is most widely adopted as an option for treatment at various stages of the disease in sub-Saharan Africa due to its cost-effectiveness, applicability at various stages, and the reduced cost of follow-up. Nevertheless, most patients in the region present with the disease in the advanced stage and despite surgery the prognosis is poor.

Published: December 2019

No Brasil, a aplicação da abordagem investigativa no ensino de ciências e disciplinas científicas constitui-se em um dos eixos formativos previstos na  Base Nacional Comum Curricular (BNCC). No entanto, o ensino de ciências e biologia por investigação não está incorporado de maneira abrangente ao planejamento escolar e sua inclusão configura-se um desafio muito grande para os professores. Na Educação de Jovens e Adultos (EJA) essa situação se magnífica pois não há diretrizes de ensino específicas descritas nos documentos oficiais. O presente trabalho apresenta os resultados de uma pesquisa de intervenção pedagógica encoberta que avaliou a aplicação de uma sequência de ensino investigativa (SEI) sobre “Poluição”, aos alunos de uma turma de Jovens e Adultos (EJA) de uma escola pública brasileira.  Avaliaram-se os impactos nos seguintes aspectos: motivação para aprendizagem, experiência ao participar e conhecimento metacognitivo. Os resultados indicam a ampliação da participação, demonstração de interesse e compromisso, aumento da satisfação, confiança, interação e colaboração dos alunos.
O cosmos bíblico e sua representação no esquema do tabernáculo
Authors: Quintão de Carvalho Ulisses , Dos Santos Costa Valeriano
Published: December 2019

A grande aventura intelectual do homem, iniciada há milênios, moveu seu olhar para além dos limites do horizonte observável, lançando-o numa incansável busca pelo conhecimento do mundo físico, bem como dos limites nos quais estivesse circunscrita a realidade do universo criado. Não se pode negar que também nas Sagradas Escrituras uma parcela significativa do esforço da humanidade em dilatar a compreensão do mundo tenha sido consignada, de tal modo a ser possível encontrar vestígios de um modelo cosmológico no esquema do santuário portátil onde os hebreus depositavam a arca da Aliança e demais objetos sagrados do culto ao seu Deus Único; uma representação do cosmos em miniatura.
Fear and Silence Meet Ignorance
Authors: Tilley-Lubbs Gresilda A.
Published: December 2019

When I studied in Spain in 1969 and 1970, I knew about the Spanish Civil War (1936–1939), briefly mentioned in my Spanish history books; General.simo Francisco Franco declared victory. I knew Spain through my graduate studies in Spanish literature and through Michener’s book Iberia (1968). In 2000, I met Jordi Calvera, a Catal.n whose post-war stories conflicted with that idyllic Spain. I returned to Spain in 2013, still with no idea of the impact of the totalitarian dictatorship based on fear and silence through which Franco ruled until his death in 1975, leaving a legacy of fear and silence. In Barcelona, I met a group of adults in their eighties who shared Jordi’s experience. My intrigue with these stories led me to learn more about the war, the dictatorship and the aftermath by interviewing people whose lives had been touched by those years. Through a layered account, I present some of the stories and examine my oblivion.
