Entwicklung einer Cantileverkalibriereinrichtung
Authors: Dannberg Oliver , Kühnel Michael , Fröhlich Thomas
Published: September 2020

Das Messen kleiner Kräfte ist in vielen wissenschaftlichen Bereichen, wie beispielsweise der Physik oder Biologie, erforderlich. Bei Kräften im Bereich von Nanonewton werden typischerweise AFM-Cantilever als Kraftsensoren genutzt. Die Steifigkeit des Cantilevers muss bekannt sein um von der Durchbiegung auf die Kraft zu schließen. Aufgrund von Fertigungsabweichungen kommt es zu einer großen Streuung der Cantileversteifigkeit. Für eine präzise Kraftmessung muss daher jeder einzelne Cantilever kalibriert werden. Das derzeit genauste Kalibrierverfahren basiert darauf die Kraft-Weg-Kennlinie des Cantilevers statisch zu messen und ihren Anstieg zu bestimmen. In diesem Artikel wird ein neuartiger Prüfstand beschrieben welcher nach diesem Prinzip arbeitet. Ein Interferometer misst die Position und eine neuartige, eingelenkige Wägezelle die Kraft des Cantilevers. Die Wägezelle wurde in zwei unabhängigen Experimenten mit übereinstimmendem Ergebnis kalibriert. Abschließend werden die Messergebnisse einer Cantileverkalibrierung präsentiert.
Could Russia Embrace an Energy Transition?
Authors: Tynkkynen Veli-Pekka
Published: September 2020

By examining how power is constructed and maintained in Russia with the help of hydrocarbons—oil and gas—this article shows why this system is detrimental to Russia in the context of global environmental, technological, and geopolitical changes. While promoting a hydrocarbon culture as central to national identity, the Kremlin has failed to adapt to the global transition toward renewable energy. But external actors such as the European Union could encourage change from within to develop Russia’s untapped potential as a green power, given its vast endowments of renewable resources.
One and Many: Parish Church Planning in Late Medieval England
Authors: Stewart Zachary
Published: September 2020

Recurrent in architectural historiography is the notion that large-scale building projects in premodern societies were inherently elite undertakings. In One and Many: Parish Church Planning in Late Medieval England, Zachary Stewart examines a well-known but inadequately studied exception to this rule: themedieval parish church. He focuses on formally integrated parish churches built in England during the two centuries between the Black Death (1348–49) and the HenricianReformation (1534–47), a paradigmatic example being the grandmarket church of St. PeterMancroft inNorwich (ca. 1440–65). Analysis of the facture, form, and function of these buildings, whose flexible configuration can be compared to the modern “open plan,” suggests that they empowered a broad spectrum of individuals to negotiate the complex relations that defined the parish as a one-and-many social entity.
FİRMA RİSKİ VE YÖNETİŞİM KALİTESİNİN HİSSE SENEDİ VOLATİLİTESİNE ETKİSİ: PARKİNSON VOLATİLİTE MODELİ İLE BİR UYGULAMA
Authors: LEVENT Cüneyd Ebrar
Published: September 2020

Bu çalışmanın amacı firma riski ve yönetişim kalitesinin hisse senedi volatilitesine etkisini analiz etmektir.  Bu etki, kurulan iki ayrı ekonometrik modelle incelenmiş, yöntem olarak panel veri analizi yöntemi seçilmiştir. Araştırma, 2008-2017 yılları arasında Borsa İstanbul’da sürekli olarak işlem gören ve finans sektörü dışındaki 64 şirketi kapsamaktadır. Araştırmanın bağımlı değişkeni olan hisse senedi volatilitesi, varlık fiyatlarının Brownian hareketini izlediğini varsayan ve Parkinson (1980) tarafından önerilen volatilite modeline göre saptanmıştır. Araştırmanın ilk bağımsız değişkeni firma borç riskidir. Diğer bağımsız değişken olan yönetişim kalitesi ise iki farklı yöntemle belirlenerek ayrı modellerde yer almıştır. Modellere literatür ile uyumlu olarak çeşitli kontrol değişkenleri ilave edilmiştir. Panel veri analizi bulguları, firma riskinin artmasının volatiliteyi istatistiksel olarak anlamlı bir şekilde arttırdığını göstermektedir. Bu araştırmada ayrıca firmaların yönetişim kalitesinin, hisse senetlerinin volatilitesini negatif yönde etkilediği de saptanmıştır. Buradan düşük borç riskine sahip, riski iyi yönetebilen ve kurumsal yönetimi iş süreçlerine dahil eden firmaların hisse senetlerinin, finansal piyasalardaki dalgalanmalardan daha az etkilendikleri sonucuna ulaşılmaktadır.

Identification of Genes Involved in the Differentiation of R7y and R7p Photoreceptor Cells inDrosophila
Authors: Earl James B , Vanderlinden Lauren A , Jacobsen Thomas L , Aldrich John C , Saba Laura M , Britt Steven G
Published: September 2020

The R7 and R8 photoreceptor cells of the Drosophila compound eye mediate color vision. Throughout the majority of the eye, these cells occur in two principal types of ommatidia. Approximately 35% of ommatidia are of the pale type and express Rh3 in R7 cells and Rh5 in R8 cells. The remaining 65% are of the yellow type and express Rh4 in R7 cells and Rh6 in R8 cells. The specification of an R8 cell in a pale or yellow ommatidium depends on the fate of the adjacent R7 cell. However, pale and yellow R7 cells are specified by a stochastic process that requires the genes spineless, tango and klumpfuss. To identify additional genes involved in this process we performed genetic screens using a collection of 480 P{EP} transposon insertion strains. We identified genes in gain of function and loss of function screens that significantly altered the percentage of Rh3 expressing R7 cells (Rh3%) from wild-type. 36 strains resulted in altered Rh3% in the gain of function screen where the P{EP} insertion strains were crossed to a sevEP-GAL4 driver line. 53 strains resulted in altered Rh3% in the heterozygous loss of function screen. 4 strains showed effects that differed between the two screens, suggesting that the effect found in the gain of function screen was either larger than, or potentially masked by, the P{EP} insertion alone. Analyses of homozygotes validated many of the candidates identified. These results suggest that R7 cell fate specification is sensitive to perturbations in mRNA transcription, splicing and localization, growth inhibition, post-translational protein modification, cleavage and secretion, hedgehog signaling, ubiquitin protease activity, GTPase activation, actin and cytoskeletal regulation, and Ser/Thr kinase activity, among other diverse signaling and cell biological processes.
Bioética en la experimentación con seres humanos
Authors: Esquivel José Miguel
Published: September 2020

In the practice of medicine, knowledge is used with a specific, concrete purpose: to prevent, alleviate or cure the ailments of a sick human being. For this purpose, one has to take and use knowledge of philosophy, anatomy, biochemistry, microbiology, genetics, nuclear medicine, immunology, pathology, etc., but also from the physics of chemistry, etc., and even more of psychology, of society and also of ethics. What should be emphasized is the global vision, the holistic conception of the patient. This raises a progressive subdivision and superspecialization of medical knowledge, generating problems of an epistemological-didactic order and even of an ethical order.

In this article, the authors meditate on social justice, sexuality and the link between this these two concepts towards a more inclusive and respectful society. Our approach responds to an educational model centered in the respect of the different types of sexual biographies, starting from the principle that the lack of social justice implies a decrease in the emotional and sexual experience of people. This paper is based on a review and consideration around Costa Rican theory and reality as seen in the current media. There is also a suggestion of a series of good practices and some conclusions for the strengthening of social justice and ergo an emotional and sexual well-being of people.
Evaluación de estrategias de enseñanza orientadas a competencias: Una comparación de caso entre estilo orientado a la competencia y el orientado al contenido
Authors: Zapico Martín Gonzalo
Published: September 2020

Teaching-learning processes are a matter of enormous profusion both in terms of theory and practice. Nonetheless, among the teaching strategies used by the teacher, two types can clearly be distinguished: classic or content-focused and focused on skills training. The hypothesis of this study is that the use of teaching strategies oriented to competencies will result in a higher rate of academic success as well as a relative rise in the ratings. For this purpose, a quantitative comparison between the performance obtained by a group of students of the subject Grammar IV, in which the teacher used strategies based on the content and compared them with another group of students who attended the same subject with the other quarter was performed, but where this same teacher used teaching strategies based on skills training. The results suggest that the use of teaching strategies oriented to competencies improve the performance of the students in both written and oral assessments, even when the assessment are content based.

Mobile learning is a field of research and educational practice that is rapidly expanding, so it is necessary to know its potential in education and learning. In this paper, we report on the results of a study with the objectives of knowing, identifying, and assessing applications, frequency, benefits, difficulties that mobile devices represent to enable ubiquitous and mobile learning of college students. Through questionnaires and protocols of life histories, an intercontinental sample with the participation of 875 students from eight countries was accessed. The main findings show that the laptop still is preferred for Internet access over the mobile phone, as well as for academic activities: preparation of work, study, search for information, exchange of notes and group work. However, the mobile phone is increasing its acceptance among students to achieve learning.
El giro decolonial en el siglo XXI
Authors: Rodríguez Reyes Abdiel
Published: September 2020

This paper analyzes the Decolonial Turn in the XXI century. The theoretical reflection on the Decolonial Turn is recent and is linked to Latinos at North American universities. There is still no accurate definition for it or a homogeneous community that can be strictly circumscribed to it. This is a developing concept, which is worked out by a heterogeneous group of professors and intellectuals who combine theory and practice to make sense of a series of serious concerns related to the criticism of the coloniality of power. Given the breadth of the subject, I will just mention a few topics, authors, and literature to get an idea about it.

Published: September 2020

To be a good teacher, it is necessary to be well prepared in various aspects of this profession. For example, it is necessary to acquire the expertise or the specific quality of the teacher who has become an expert through the daily practice of it (Carretero, 1987). Thus, language teachers who teach their language in another country, in addition to this path to experience, will also have to resolve the cognitive conflicts typical of an encounter between cultures.

Desapropiación del discurso y apertura en "Cuando los Ángeles juegan a la suiza"
Authors: González Campos Guillermo
Published: September 2020

One of the most salient features of contemporary literature is self-awareness. At present, the creative process is influenced by the concepts that are produced about the literary phenomenon in academic settings. In this sense, as Amoretti (1995) points out, regarding the concept of intertextuality, that literary theory has become not only a space to reflect on the phenomenon of writing, but it also constitutes a valuable resource for creators, who, thanks to this type of knowledge, explicitly and consciously have various strategies that are used in the textualization process.

Published: September 2020

The word wanders through infinite language communicative discourses.The word is never unique, absolute, or abstract, even when its silence seems absent. It is always a source that brings meaning to life. Any word means openness and expressive action. It is its way of talking because it becomes writing and a  dialoguing verb (any sign, icon, graph, or shape) in order to create that visual and audible body that becomes meaningful to itself and to other receptors -its audio-listeners, video-listeners, radio-listeners, TV-listeners... phono-listeners-. lt is in this process of listening to a word or words where the reality of being becomes real. Leaming how to listen is leaming how to live from and with the word or words which are the ones that talk with all the reason senses.

Autorregulación de los procesos de composición escrita en estudiantes universitarios de primer ingreso de la carrera Asistencia Veterinaria de la Universidad Técnica Nacional, Sede Atenas
Authors: Castro Campos María Lourdes
Published: September 2020

First-year college students require an educational environment that will provide the foundation for their integral development. For this reason, classrooms should foster an environment of free communication and full development. These students are considered inexperienced or novice writers because they do not plan, do not set goals, do not take into account the audience, and do not have enough knowledge about strategies for essay writing in general. Thus, it would be ideal that in college, writers maximize their potential and transform not only their writing pattern but their knowledge in general starting from reflection and the discursive quality that they employ. All this can be accomplished with some self-regulation that would allow them to take over their text and make their writing autonomous since it originates from their particular perspective and according to their personal conceptions and socio-emotional ideology.
Impacto de la formación científica secundaria en dos comunidades indígenas Cabécar y Ngäbe
Authors: León León Giselle , Méndez Masís Daniel Enrique , Vargas Acuña Ericka
Published: September 2020

This paper presents the results of a research about the impact of the language level, values, and traditions of secondary education in tenth grade Biology at two high schools located in Cabécar and Ngäbe indigenous territories. This research was based on a mixed approach, taking into account the different kinds of instruments used. Two groups of eleventh grade (students) and two biology teachers from two different high schools were surveyed in order to gather the information. The interviews' results are shown through a descriptive analysis. The main conclusions were the following: Although the educational system applied in these communities promotes the development of their autonomous values and traditions, only few of them are still present. Moreover, this research found out that biology professionals (teachers) promote the Indigenous identity by contextualizing the mediation process. Additionally, this research evinced the importance of speaking the indegenous students’ native language in the classrooms and the importance of the lessons being taught by Cabécar or Ngäbe people.

Análisis de los sistemas de planeación estratégica como soporte académico para la carrera de Manejo de Recursos Naturales de la Universidad Estatal a Distancia
Authors: Ulate Sánchez Rosita
Published: September 2020

This article describes an exploratory qualitative study with a comparative documental analysis of the mission statement of  Distance State University of Costa Rica (UNED, for its acronym in Spanish), the School of Exact and Natural Sciences as well as the major of Naural Resource Management. The purpose was to know the correspondence between the learning objectives stated in each of the institutional hieararchical levels in light of the mission statements of the parties involved. To review the consulted documents, the researcher used theOrganizatoinal Element Model (OEM) proposed by Kaufman, Watkins and Leigh (2001), in which the actions of the mega, macro, and micro and operational levels of an educational organization are examined. This type of administrative tools make it possible to visualize the existing gap between what is stated in the mission statement of the managerial levels and what is done in the subsequent hierarchical levels of the organization. Additionally, the study was complemented by a comparison of the Strengths, Weaknesses, Opportunities, and Threats (SWOT) of the organization to indentify possible actions to bring about change in the planning management towards a culture that links teaching, outreach, and research. The findings evidence a series of weaknesses in the academic and administrative management proposals with regard to the basis for strategic plannic such as stating a mission, which deals with decision-making and structural changes that affect the quality of the teaching/learning processes in the program of the manjor of Natural Resource Management.

This paper reviews the institutional, scientific and technical documentation regarding the availability of water for human consumption, policy tandem, setting tariffs, subsidies unit price of water and anthropocentric and ecoperipheral life styles in order to compare the psychosocial approach with the economic approach. For this purpose, information was sought in databases indexed with ISSN and DOI registration DIALNET LATINDEX and REDALYC during the period from January 2010 to October 2014. This article, with regard to to the state of knowledge, reveals that both approaches have been overwhelmed by the socio-political relations in pre and post-electoral periods. Therefore, addressing the problem is proposed from a sociopolitical concept to explain and anticipate confrontations between actors in contexts of politicization of water.

Authors: Aguilar Álvarez Rolando , Ramírez Martinell Alberto
Published: September 2020

In recent years, Interactive Whiteboards (IWB) have gained a respected space within the academic practitioners in the university context. In this article, we will do a revision of these devices going from their main components, their implications in the teaching-learning process within Higher Education Institutions (HEI) and the way they can be configured in the classroom. We also reflect on the academic possibilities generated from their use and how their components may enhance the classroom experience. In this way –and reflecting upon given specific situations– we compare the singularities of different configurations of the IWB components and the implications for their integration in HEI as justified and useful didactic resources.

Published: September 2020

It has not always been easy to be a woman. Throughout history, women have been struggling to have a place in society and to be respected despite of different sacrifices and humiliations that they have had to face in their lives.As a matter of fact, in spite of living under specific rules or customs imposed by society, women have fought to raise their voices and make their rights known through courage, faith, and optimism. Hence, they could be accepted without any judgments and be part of society without any discrimination.

Education is a continuous and permanent process that aims to gradually bring human beings closer to perfection while allowing them to project themselves on the individual and social planes, with the ultimate purpose that such fulfillment and perfection contribute to the progress of people around them, their community, and society in general.
¿Qué sabemos que se enseña en filosofía?: El currículo oculto de una formación filosófica
Authors: Ureña Soto Omar J. , Mata Calderón Adrián
Published: September 2020

Questions such as the following: what is philosophy for? Why study philosophy? What is the social product that a philosopher contributes? Where is the discipline going? What does a philosopher do? find absolutely dissimilar answers due to who the interlocutor may be. Now, within the logic of development, typical of the neoliberal governments of Latin America and from the imperialist perspective, or from the so-called technical or productive majors, the answer is unequivocal: Philosophy is an anachronistic discipline, meaning that it does not respond to the interests of the market.
Activated carbon from thermo-compressed wood and other lignocellulosic precursors

Published: September 2020

The effects of thermo-compression on the physical properties such as bulk density, mass yield, surface area, and also adsorption capacity of activated carbon were studied. The activated carbon samples were prepared from thermo-compressed and virgin fir-wood by two methods, a physical activation with CO2 and a chemical activation with KOH. A preliminary thermo-compression method seems an easy way to confer to a tender wood a bulk density almost three times larger than its initial density. Thermo-compression increased yield regardless of the mode of activation. The physical activation caused structural alteration, which enhanced the enlargement of micropores and even their degradation, leading to the formation of mesopores. Chemical activation conferred to activated carbon a heterogeneous and exclusively microporous nature. Moreover, when coupled to chemical activation, thermo-compression resulted in a satisfactory yield (23%), a high surface area (>1700 m2.g-1), and a good adsorption capacity for two model pollutants in aqueous solution: methylene blue and phenol. Activated carbon prepared from thermo-compressed wood exhibited a higher adsorption capacity for both the pollutants than did a commercial activated carbon.
Genetic predisposition in pediatric oncology

Identifying patients with a genetic predisposition for developing malignant tumors has a significant impact on both the patient and family. Recognition of genetic predisposition, before diagnosing a malignant pathology, may lead to early diagnosis of a neoplasia. Recognition of a genetic predisposition syndrome after the diagnosis of neoplasia can result in a change of treatment plan, a specific follow-up of adverse treatment effects and, of course, a long-term follow-up focusing on the early detection of a second neoplasia.

Responsible for genetic syndromes that predispose individuals to malignant pathology are germline mutations. These mutations are present in all cellsof conception, they can be inherited or can occur de novo.

Several mechanisms of inheritance are described: Mendelian autosomal dominant, Mendelian autosomal recessive, X-linked patterns, constitutional chromosomal abnormality and non-Mendelian inheritance.

In the following review we will present the most important genetic syndromes in pediatric oncology.
A review of the current understanding of nanoparticles protein corona composition
Authors: Breznica Pranvera , Koliqi Rozafa , Daka Arlinda
Published: September 2020

Upon entering into the biological environments, the surface of the nanoparticles is immediately coated with proteins and form the so-called a protein corona due to which a nanoparticle changes its "synthetic" identity to a new "biological" identity. Different types of nanoparticles have different protein binding profiles, which is why they have different protein corona composition and therefore it cannot be said that there is a universal protein corona. The composition and amount of protein in the corona depends on the physical and chemical characteristics of the nanoparticles, the type of biological medium and the exposure time. Protein corona increases the diameter but also changes the composition of the surface of the nanoparticles and these changes affect biodistribution, efficacy, and toxicity of the nanoparticles.
НАУКА В РОЗВИТКУ ЕКОНОМІКИ УКРАЇНИ ТА ОКРЕМИХ КРАЇН СВІТУ

Аналіз досягнень багатьох країн світу –– економічних лідерів надає можливість зробити однозначний висновок: наука в сучасному середовищі є стратегічно важливим ресурсом держави, а рівень науково-технічного розвитку країни формує одну із складових національної безпеки.Українська економіка протягом 30-річного періоду її реформування зазнала глибокого занепаду, тоді як економіки багатьох провідних країн світу демонструють високі темпи зростання, що забезпечує гідний рівень добробуту їх громадян. Результати досліджень доводять, що надзвичайно важливу роль у розвитку економіки держав в умовах нинішнього глобалізованого світу відіграє наука –– завдяки розробці, вдосконаленню і створенню високопродуктивної техніки, новітніх технологій та забезпеченню інноваційного розвитку і високої ефективності виробництва конкурентоспроможної продукції на підприємствах для внутрішнього споживання і на експорт.Статистичні дані свідчать про мізерність коштів, які виділяють на здійснення наукових досліджень і розробок в Україні за всіма існуючими джерелами їх фінансування. Проведені аналітичні дослідження виявили катастрофічне відставання України від країн з високорозвинутою економікою за обсягами фінансування науки, показниками наукомісткості ВВП, обсягами виробництва і експорту високотехнологічної продукції, надходженнями грошових ресурсів від експорту продукції та послуг у розрахунку на 1 особу населення, що обумовлено, перш за все, занепадом вітчизняної науки.Зроблено висновок, що в системі стратегічних державних заходів щодо забезпечення життєво необхідного зростання економіки, підвищення рівня добробуту громадян, майбутнього України, пріоритетним напрямом необхідно визнати невідкладне відновлення розвитку науки до її нинішнього рівня в економічно розвинутих країнах.
Delayed Presentation of Meconium Ileus in an Infant With Cystic Fibrosis

Published: September 2020

Although infants with meconium ileus usually present with apparent symptoms shortly after birth, the diagnosis of meconium ileus and cystic fibrosis (CF) may be delayed, awaiting newborn screening (NBS) results. We present the case of an 11-day-old term girl with delayed passage of meconium at 48 hours who had 2 subsequent small meconium stools over the following week. There was a normal feeding history and no signs of abdominal distension or distress. She then presented with an acute abdomen, decompensated shock, bowel perforation, and peritonitis, requiring multiple intestinal surgeries. Her NBS for CF was positive, and CF was ultimately confirmed with mutation analysis. Her course was complicated by prolonged parenteral feedings and mechanical ventilation via tracheostomy. The infant was managed with soy oil, medium chain triglycerides, olive oil, fish oil lipids and experienced only transaminitis without cholestasis and no chronic liver sequelae, with subsequent normalization of her transaminases without treatment. Because her only symptom was decreased stool output and NBS results were unavailable, the CF diagnosis was delayed until she presented in extremis. Delayed meconium passage and decreased stool output during the first week of life should lead to suspicion and additional evaluation for CF while awaiting NBS results. Careful monitoring is indicated to prevent serious, life-threatening complications. The use of soy oil, medium chain triglycerides, olive oil, fish oil lipids for infants requiring prolonged parenteral nutrition may also be considered proactively to prevent cholestasis, particularly for high risk groups.
