Authors: Félix Adriano da Silva , Nascimento José Wallace Barbosa do , Melo Daniele Ferreira de , Furtado Dermeval Araujo , Santos Adriana Maria dos
Published: March 2020

Um dos problemas na agropecuária mundial é produzir sob efeito das mudanças climáticas, e esta atividade propicia impacto ao meio ambiente, principalmente na geração de gases do efeito estufa. Portanto o objetivo do presente trabalho será realizar uma análise exploratória sobre a situação e adaptação da produção vegetal em meio às mudanças climáticas, o reflexo de sua degradação na saúde humana, identificando as opções de mitigação das emissões causadas por atividades agrícolas e as oportunidades associadas a elas. As mudanças climáticas afetarão a produção vegetal, influenciando na adaptação de algumas culturas, com impactos negativos, a exemplo o café com uma estimativa de perda de 40%, e impactos positivos, como na cana-de-açúcar. Haverá necessidade de ampliação de pesquisas para diferentes manejos e tratamentos no ambiente de plantações e criação de animais, trazendo sustentabilidade para o meio, qualidade produtiva, e, ao fim da análise, observa-se os benefícios positivos de inserir na atividade agrícola o viés ambiental na redução dos impactos ao meio ambiente.

Authors: Guedes Dartagnan Pinto , Silva André Luís dos Santos
Published: March 2020

Os objetivos do estudo foram: (a) identificar e comparar as propriedades psicométricas da versão brasileira do questionário National College Health Assessment II (NCHA IIc) nos formatos impresso e on-line; e (b) verificar a capacidade de concordância entre os dados levantados por ambos os formatos. Ambos os formatos do questionário foram preenchidos por 371 estudantes universitários voluntários. Para identificar as propriedades psicométricas foi calculado coeficiente alfa de Cronbach (consistência interna) e realizada análise fatorial confirmatória e de multigrupo. A concordância entre os modelos foi medida por meio do percentual de concordância, estatística Kappa e coeficiente intraclasse. Os resultados do estudo indicam que a versão brasileira on-line do NCHA IIc forneceu dados de qualidade semelhante ao formato impresso tradicional, com vantagens logísticas e de custos substanciais, possibilitando, desse modo, sua aplicação em estudos futuros com finalidade de analisar condutas de proteção e risco para saúde de estudantes universitários no Brasil.

Published: March 2020

O aumento da expectativa de vida vem fazendo crescer, no Brasil, o número de Instituições de Longa Permanência para Idosos (ILPI), as quais devem investir na qualidade de vida de seus residentes. Nesse contexto, convém refletir sobre a importância da promoção da saúde junto a pessoas institucionalizadas, ressaltando aspectos interacionais, pois é por meio da participação social que elas podem permanecer ativas e integradas à comunidade em que vivem. Como objetivo de compreender o papel que atividades dialógicas assumem na promoção da saúde de idosos institucionalizados, o presente estudo, de caráter qualitativo, pautou-se na análise dialógica do discurso e contou com a participação de 14 residentes de duas ILPI, situadas no Sul do Brasil. Eles participaram de 16 encontros grupais, com duração de 90 minutos, que ocorreram semanalmente, em cada ILPI. Na visão dos idosos, práticas dialógicas proporcionaram-lhes bem-estar, contribuindo para que enfrentassem a rotina da instituição.

O presente estudo objetivou analisar as condições socioeconômicas, de saúde e hábitos de vida dos catadores de material reciclável em duas cooperativas no município de Guanambi - Bahia, Brasil. Trata-se de uma pesquisa de natureza descritiva, analítica e exploratória e todos os catadores foram entrevistados por meio de um questionário semiestruturado. Houve predominância da faixa etária entre 30 a 58 anos (80%) (p = 0,007), pardos (55%) (p = 0,02), casados (45%) (p = 0,02), com 2 a 3 filhos (55%) (p = 0,03). Os catadores informaram que começaram a trabalhar com menos de 18 anos (85%) (p = 0,002), e recebem uma renda mensal de até 1 salário mínimo com o trabalho de reciclagem (75%) (p = 0,02). Em relação às condições de saúde, 75% afirmaram que possuem Equipamentos de Proteção Individual (EPI) (p = 0,02), no entanto 80% (p = 0,02) não utilizaram o EPI e não consideram que seu trabalho pode provocar problema de saúde (75%) (p = 0,02). Percebe-se que os catadores de material reciclável precisam intensificar o uso dos EPI’s, visando minimizar os danos com a saúde, além de melhorias na renda e na qualidade de vida.
Cyclical causalities between the U.S. wholesale beef and feed prices: A Markov-switching approach
Authors: Ozdemir Dicle
Published: March 2020

Abstract: This paper examines whether some major livestock feed prices as corn, sorghum, hay and barley play a leading role in the regime switching dynamics between two states of the beef price cycles and have nonlinear effects on wholesale beef market in the U.S. using time-varying transition probability Markov-switching autoregressive model (TVTP).  The study reveals that real wholesale beef price movement in the U.S. red meat market exhibits a nonlinear two regimes pattern. This evidence indicates that livestock feed prices provides some predicted power to the model of beef price regime switching and supports livestock feed prices contributing to whether the beef price levels remains in high-mean regime.

Published: March 2020

This paper validates, with a linear model, the theoretical construction that specifies negative relationship between interest rate differential and exchange rate in the BRICS countries. Further probe with a nonlinear model reveals that exchange rate responds asymmetrically to interest rate differential in the countries. In all, we show that accounting for asymmetry and structural breaks enhance the relationship.
“¿Por qué no decir, pues, una evidente trivialidad?” Irrupciones vitales e irrupciones teóricas en Diario anónimo, de José Ángel Valente
Authors: Prósperi Germán Guillermo
Published: March 2020

Resumen: La publicación de Diario anónimo (1959-2000), de José Ángel Valente, supuso una oportunidad única para conocer algunos aspectos de la vida del escritor no presentes en el resto de su obra. El volumen es la constatación de que el diario es para Valente un espacio en el que ensayar una escritura fragmentada, no por la forma que adopta el texto, sino por las interrupciones, rupturas o desapariciones que se manifiestan como provocación en la vida del poeta. Este artículo analiza los momentos en los que el Diario figura la dimensión de la intimidad, caracteriza el tono en que el diarista se refiere a los hechos que la determinan y postula que esta escritura debe ser leída en serie con algunos textos poéticos y teóricos que ofrecen la imagen de un diarista en devenir, nunca acabada. Palabras clave: diario; intimidad; irrupciones; José Ángel Valente; Roland Barthes. Abstract: The publication of Diario anónimo (1959-2000), by José Ángel Valente, was a unique opportunity to learn some aspects of the writer’s life that are not present in the rest of his work. The volume is the realization that the diary is for Valente a space in which to try a fragmented writing, not through the form adopted by the text, but through the interruptions, ruptures or disappearances that the life of the poet shows as a provocation. This article analyzes the moments in which the Diario includes the dimension of intimacy, characterizes the tone in which the diarist refers to the facts that determine it and postulates that this writing must be read in series with some poetic and theoretical texts that offer the image of a diarist in becoming, never finished. Key words: diary; intimacy; irruptions; José Ángel Valente; Roland Barthes.
José Ángel Valente como escritor gallego. Notas sobre la influencia de Vicente Risco y Rosalía de Castro
Authors: García Candeira Margarita
Published: March 2020

Resumen: Este artículo ahonda en la vinculación de José Ángel Valente con la literatura y la cultura gallegas. Se examinan ciertas intertextualidades significativas presentes en el poemario Cántigas de alén y en otros textos, que revelan la huella insoslayable de Vicente Risco a la hora de establecer una lógica del asentamiento que viene a contradecir la poética explícita del autor (fundada, como se sabe, sobre una potente conciencia exílica) y que acaba proyectándose sobre la lectura que Valente hace de Rosalía de Castro. Materiales como la biografía, las cartas, el Diario anónimo o el catálogo de la biblioteca del poeta permiten contextualizar estas deudas en un entramado de sociabilidad afectiva e intelectual que ayuda a comprender la incardinación específica del poeta en el espacio cultural gallego, caracterizado por el conflicto y la diáspora. Palabras clave: José Ángel Valente; literatura y cultura gallegas; Cántigas de alén; Vicente Risco; Rosalía de Castro. Abstract: This article explores José Ángel Valente’s link to Galician literature and culture. Meaningful intertextual presences displayed in the collection Cántigas de alén and in other texts are evaluated. They reveal the inescapable mark of Vicente Risco in establishing a logics of settlement that comes to contradict the explicit poetics of the author (founded, as known, on a strong conscience of exile) and which ends up projected upon Valente’s reading of Rosalía de Castro. Materials as biographies, letters, the Diario anónimo and the catalogue of Valente’s personal library allow to contextualize these debts within a framework of intellectual and affective sociability that helps to understand the poet’s specific incardination in the Galician cultural space, as characterized by conflict and diaspora. Key words: José Ángel Valente; Galician literature and culture; Cántigas de alén; Vicente Risco; Rosalía de Castro.
Seismotectonics of the 2017–2018 Songyuan Earthquake Sequence, Northeastern China: Passive Bookshelf Faulting and Block Rotation in the Songliao Basin
Authors: Su Zhe , Xu Xi-Wei , Liang Shan-Shan , Wang Erchie
Published: March 2020

The high frequency of earthquake clusters generated by pure strike-slip faulting over the past 3 yr (beginning in 2017 in the Songliao basin, northeastern China) has motivated us to consider why lateral strike slip and not extension determines the seismic activity within the Songliao basin. Precise location and characterization of relocated aftershocks, forward modeling of the coseismic displacement field, and Global Positioning System (GPS) monitoring data are combined to detect the possible seismogenic structures of the Songyuan earthquake sequence. The 2017 ML 5.3 aftershock cluster coincided with the northeast-striking Fuyu–Zhaodong fault (FZF), and the 2018 aftershock swarm followed the linear trend (N42°W) of the Songhuajiang fault (SHF). In addition, the forward modeling results indicate that during the earthquakes, right-lateral and left-lateral strike-slip displacements occurred simultaneously along the FZF and SHF, respectively. These two strike-slip faults joined to accommodate the intervening crustal blocks’ asymmetrical east–west convergence and a single northward extrusion. We also utilize 5 yr of GPS data to construct the regional strain-rate map for the basin. The measurements show that right-lateral transform motion along the immense northeast-striking right-lateral strike-slip faults, for example, the Tanlu fault zone and the FZF, impose a northeast-striking simple shear across the Songliao basin. This simple shear not only caused left-lateral movement on the minor northwest-striking left-lateral strike-slip faults such as the SHF but also rotated them ∼14° clockwise into their present orientations. The results of the proposed bookshelf faulting model in which the predominant northeast-striking parallel faults are initiated are consistent with the observed lineament orientations, focal mechanisms, and earthquake distributions. The sharp shift in the subduction direction of the Pacific plate seems to have had a considerable influence on the intracontinental deformation in China, at least throughout northeastern China.
El nuevo curso de la paz, la guerra y las resistencias
Authors: Sánchez Ángel Ricardo
Published: March 2020

Se aproxima el fin de una década y el comienzo de otra. Todo aparece y se expresa de manera confusa y turbulenta, exigiendo claridad. Hay, por ello, que descifrar el significado de los relámpagos de las grandes movilizaciones en curso en distintos países y en los distintos continentes. Lo buscado es el cielo despejado de la historia.

Lo primero que constatamos es que el siglo XX, como tiempo largo de crisis, guerras, revoluciones y contrarrevoluciones, no solo no ha terminado, sino que continúa con estos registros, a los que se suma la impetuosa revolución tecnológica y digital: el espacio de lo inimaginable de la inteligencia artificial. Destaquemos que son tiempos de crisis en la acumulación económica del capitalismo y en la reproducción de las relaciones sociales y culturales. El ciclo discurre en una onda larga recesiva en la que las reanimaciones esporádicas no logran revertir esta tendencia, con mayor intensidad y proyección en unos países que en otros, pero con el lazo de la cadena de la economía del mundo. La relación entre tecnología, luchas sociales y comunicación adquirió nuevas dimensiones (Salazar, 2016).

Published: March 2020

Vigorous legislative activity is taking place regarding paid sick leave in the United States. Most existing research measures paid sick days autonomously without also considering other benefits such as flexible work and paid vacation. This descriptive study of a nationally representative sample of 4428 adult male workers finds 77.1% of workers have a combination of paid sick leave, flexible work, and vacation, while only 16.8% have just one of the three benefits. Future research should examine the correlates of combined benefit packages in terms of workers’ physical, emotional and financial health and wellbeing. Nationally representative data collection efforts should refine the measurement of workplace benefit variable to allow for these comparisons.
Performing a Metis Pedagogy in the Rhetoric and Writing Studies Classroom
Authors: Selznick Hilary
Published: March 2020

Scholars in the field of disability rhetoric (e.g. Dolmage; Price; Vidali) have long called for the denormalization of traditional approaches to the teaching of rhetoric and composition. Such approaches historically characterize rhetoric as disembodied and ask students to compose straight, linear, alphabetic texts which privilege meaning-making through written discourse and remain inaccessible to diverse users and audiences. As a response, this article recounts how I applied the concept of metis—double, divergent, crooked—as a theoretical framework for a special topics course "Disability, Rhetoric, and the Body," and as an alternative pedagogical approach to the teaching of rhetoric and composition. More specifically, this article explores the connection between my own metis-work as a teacher-scholar and my students' performance of metis through multimodal composing and analysis. As a result, the rhetoric and composition classroom becomes a non-normative space where difference is not only valued, but celebrated.

Authors: Almaskari Ahmed A. , Al Noumani Huda , Al-Omari Khalid , Al Maskari Mohammed A.
Published: March 2020

ABSTRACT: Objectives: Little is known about nurses’ and patients’ perceptions of learning needs following coronary artery bypass graft (CABG) surgery in Oman. This study aimed to identify patients' and nurses' perceptions of post-CABG learning needs. Methods: This cross-sectional study was conducted in two cardiac units in Oman between February and April 2018. Participants were from step-down units and perceptions of post-CABG learning needs were collected using a modified version of the Cardiac Patients Learning Need Inventory (MCPLNI) questionnaire. Data were analysed using descriptive and inferential statistics. Results: A total of 90 patients and 90 nurses were included in this study (response rate: 100%). Nurses perceived information about chest and leg wound care, medications and complications as patients’ most important learning needs (4.89 ± 0.31, 4.84 ± 0.33 and 4.78 ± 0.45, respectively). Similarly, patients perceived a need for post-CABG learning related to chest and leg wound care, complications and medication, while learning related to physical activity received a moderate priority (4.92 ± 0.20, 4.80 ± 0.45, 4.85 ± 0.26 and 3.50 ± 1.34, respectively). Conclusion: Before discharging patients, they should be provided with specific information related to post-CABG care. It is essential to assess patients’ learning needs and incorporate those learning needs into discharge plans.Keywords: Learning; Perception; Coronary Artery Bypass; Education; Patients; Nurses; Oman.

Published: March 2020

ABSTRACT: New groups of high-grade neuroepithelial tumours (HGNET) have emerged from the reclassification of central nervous system (CNS) embryonal tumours that have recognised CNS HGNET with BCOR alteration (CNS HGNET-BCOR). We report a two-year, nine-month-old Omani boy who presented to the Royal Hospital, Muscat, Oman, in 2015 with subacute head tilting and neck pain. A well-defined cerebellar lesion was found and he was treated with standard chemoradiotherapy. After a relapse at the age of five years, molecular testing revealed a BCOR alteration. He was treated with further surgery and high-dose chemotherapy; unfortunately, he relapsed and died three years after he was diagnosed.Keywords: Neuroepithelial Tumor; Glioblastoma; Human BCOR Protein; Embryonal Tumors; Case Report; Oman.

Authors: Sayed Nabeel , Bakathir Abdulaziz , Pasha Mehboob , Al-Sudairy Salim
Published: March 2020

Objectives: This retrospective study aimed to investigate complications associated with the extraction of third molars at a tertiary healthcare centre in Oman. Methods: All consecutive patients who underwent extraction of one or more impacted third molars under general anaesthesia at Sultan Qaboos University Hospital, Muscat, Oman, between January 2007 and December 2017 were included. Age, gender, indication for extraction, teeth removed, procedure and complications were recorded. Results: A total of 1,116 third molars (56% mandibular and 44% maxillary) were extracted and the majority (67.7%) were from female patients. The mean age at extraction was 24 ± 5 years and most patients (77.7%) were 20‒29 years old. The intraoperative and postoperative complication rates were 3.7% and 8.3%, respectively. The intraoperative complications included tuberosity fracture (1.2%), root fracture (1.1%), bleeding (0.7%), soft tissue injury (0.5%) and adjacent tooth damage (0.2%). Postoperative complications were sensory nerve injuries (7.2%), swelling/pain/trismus (0.6%) and dry socket (0.5%). Nerve injury was temporary in 41 patients and permanent in four cases. A statistically significant relationship was observed between those aged 30‒39 years and dry socket (P = 0.010) as well as bone removal and all postoperative complications (P = 0.001). Conclusion: Most complications resulting from third molar extractions were minor and within the reported ranges in the scientific literature. However, increased age and bone removal were associated with a higher risk of complications. These findings may help to guide treatment planning, informed consent and patient education.Keywords: Third Molar; Tooth Extraction; Complications; Lingual Nerve; Inferior Alveolar Nerve; Oman.
Bibliometric Review of Mental Health Research in Medical Colleges of Pakistan
Authors: Farooq Rai K. , Syed Zohaib , Zulqernain Ali
Published: March 2020

Objectives: Mental health is a less frequently explored area of medical research as both developing and developed countries lack competent human resources and funding for this purpose. Reviewing mental health research can help medical professionals appreciate the progress of understanding and identify problems in this area. This systematic review examined the status of mental health research carried out in medical education institutions and tertiary healthcare hospitals across Pakistan over the past 70 years. Methods: PubMed ® (National Library of Medicine, Bethesda, Maryland, USA), was searched for articles published between 1947 and 2017 related to mental health with an emphasis on the exclusive affiliation of the first author with a medical college in Pakistan. Results: A total of 118 articles were included in this study. The number of published research-based studies has increased steadily over the past years. However, there are indicators of a lack of quality research, such as no declaration of conflict of interest or the identification of a funding source and a general lack of publications in a journal with a high impact factor. Conclusion: The findings of this study have shown a steady improvement in the quantity and quality of mental health research conducted in Pakistani medical colleges/universities. However, a lack of funding, training and faculty induction policies may be hindering the establishment of a research culture and contributing to the slow progression of mental health research in Pakistan.Keywords: Medical Education; Mental Health; Research; Psychiatry in Literature; Pakistan.

Waddling Gait: A complication of valproate therapy and a thought beyond vitamin D deficiency
Authors: Sharma Amit , Sinha Siddhartha , Narang Amit , Chouhan Dushyant K. , Gupta Sumit
Published: March 2020

Proximal muscle weakness is a common presentation in paediatric-orthopaedic clinics and is frequently paired with a vitamin D deficiency diagnosis. Recently, side effects of the extensive use of antiepileptic and antipsychotic drugs such as sodium valproate in childhood disorders are being documented. Sodium valproate causes a time-dependent, drug-induced proximal myopathy. We report a 13-year-old female patient who presented at the Orthopaedic Outpatient Department at Lady Hardinge Medical College, New Delhi, India, in 2019 with an abnormal gait. The patient was taking a combination therapy of sodium valproate, risperidone and trihexyphenidyl for absence seizures and a mood disorder. Following clinical investigations, the patient was diagnosed with proximal myopathy. As a result of elevated serum alkaline phosphatase and creatine kinase myocardial band levels, sodium valproate was replaced with ethosuximide and a carnitine supplementation was prescribed. The patient fully recovered and regained full mobility. Proximal myopathy had been incorrectly managed and assumed to be caused by a vitamin D deficiency.Keywords: Muscle Weakness; Carnitine; Myopathy; Valproic Acid; Vitamin D Deficiency; Gait; Case Report; India.
Downregulation of long non-coding RNA ZXF1 restricts cell survival by targeting miR-634-GRB2 in lung adenocarcinoma
Authors: Ren Xubin , Xu Nie , Zhang Yunting , Wang Tao
Published: March 2020

Increasing evidence demonstrates that long non-coding RNAs (lncRNAs) play important regulatory roles in mediating initiation and progression of lung adenocarcinoma (LA), which is one of the most lethal in humans. A previous study reported that lncRNAZXF1 was dysregulated in LA and enhanced expression of ZXF1 promoted the invasion and metastasis in LA. However, the effect of ZXF1 on LA progression and its underlying mechanisms were not thoroughly investigated. In our in vitro experiments, qRT-PCR revealed that the expression level of ZXF1 in LA tissues and tumor cells were significantly higher than that in adjacent normal tissues and normal cells. Furthermore, bioinformatics analysis, luciferase reporter assay, western blot and RNA immunoprecipitation (RIP) assay showed that ZXF1 could directly interact with miR-634, which targets GRB2. Therefore, we propose that ZXF1 could function as an oncogene partly by sponging miR-634 and therefore regulating GRB2 expression in LA. Overall, this study demonstrated, for the first time, that the lncRNA ZXF1/miR-634/GRB2 axis plays crucial roles in modulating LA progression. Moreover, lncRNA ZXF1 might potentially improve LA prognosis and serve as a therapeutic target for the treatment of LA.

Background. Data on the effect of the number of received oocytes on the outcomes of assisted reproductive technology (ART) programs are contradictory. The frequency of obtaining a small number of cells ranges from 5.6 to 35.1 %. Identifying women who have chances of getting pregnant, despite this situation, is important for drawing up an adequate treatment plan.

Objective of this study is to assess the pregnancy rate depending on the number of retrieved oocytes in ART cycles with ovarian stimulation, which ended with the transfer of embryos, as well as determining the characteristics of patients with a reduced response, in whom the pregnancy occurred.

Design and methods. The study included 526 women who were treated for infertility in the department of ART of the Almazov National Medical Research Centre in 2017. Patients were divided into three groups depending on the number of oocytes retrieved: less than 5, from 5 to 9 and 10 or more. Group 1 (number of oocytes less than 5) included 126 women, group 2 (from 5 to 9) — 223 women and group 3 (number of oocytes 10 and more) — 177 patients. The average age of the patients was 33.37 years (from 22 to 48 years).

Results. The frequency of obtaining a positive blood test and clinical pregnancy rate were comparable in groups 2 and 3 (53.81 % and 49.72 %, respectively) and significantly lower in group 1 (41.27 %, p > 0.05). Clinical pregnancy in group 1 occurred in 34.13 % of cases, which was significantly different from the indicators of group 2 + 3, where the gestational egg visualized in 47.5 % of cases (p < 0.05). In a group of women with a small number of oocytes, the most important predictors of pregnancy were obtaining 2 or more oocytes, and anti-mullerian hormone (AMH) level above 1 ng / L.

Conclusion. The number of oocytes is an important predictor of pregnancy rate. The chances of becoming pregnant in women with a small number of oocytes depend on the level of AMH and the number of oocytes obtained.

Vascular calcification is a widely-spread pathology with high mortality. It is active bioregulated process that is observed in pathogenesis of different desires, associated with metabolic dysfunction, congenital tissue desires and aging. Signal pathways and transcription factors that are involved in vascular calcification are also takes place in normal osteogenesis and/or vascular development. In the review the main attention is payed to the role of signaling pathways BMP (bone morphogenic protein), Notch, Wnt and to the role of transcription factors BMP2, RUNX2, Msx2 in vascular calcification. Probably, dysfunction of osteogenic signal pathways and transdifferentiation of vascular cells to osteoblast-like cells is a common prosses not only for vascular calcification or mineralization, but is a way of vascular degradation in general. Proosteogenic changes at cellular and molecular level may play role in pathogenesis of a disease without manifestation of vascular mineralization, such as thoracic aortic aneurysm. Ability of vascular cells to change their phenotype to osteophenotype is very likely biologically important ability. Over weakness of calcific signaling pathways activity can also lead to vascular pathology. The aim of the review is to overlook the mechanisms of vascular calcification focusing at the role of signal pathways and vascular cells at this process with particular attention to aortic calcification. Understanding the mechanisms of biological regulation of pro- and antiosteogenic processes in pathology and normal conditions opens new opportunities to influence this prosess in order to correct vascular pathologies.
Los infinitos de algunas series divergentes
Authors: Miramontes de León Diego , Miramontes de León Gerardo
Published: March 2020

En este trabajo interesa mostrar que dos series divergentes, aunque ambas tienen un número infinito de términos, al tener términos diferentes, su valor al infinito también difiere. En el documento se muestra que la serie armónica, dada por la suma del inverso de los números naturales, puede descomponerse en dos series. Una de ellas dada por la suma del inverso de los naturales de la forma 1/np con p > 1 y la otra, que será llamada subarmónica, formada por el resto de los términos que completan la serie armónica original. Se muestra que cada una de estas series es, una convergente y la otra divergente, obteniendo así la serie original divergente. Se incluye la demostración de la divergencia de las nuevas series, y como extensión de esta descomposición de la serie armónica, se hace una comparación de dos series subarmónicas las cuales, a pesar de ser ambas divergentes, difieren en su valor al infinito.

 

Abstract

This work aims to show that two divergent series, although both have an infinite number of terms, if they have different terms, their value to infinity also differs. In this document, it is shown that the harmonic series, given by the sum of the inverse of natural numbers, can be decomposed into two series; one of them is given by the sum of the inverse of the naturals in the form 1/np where p > 1 and the other, which will be called subharmonic, formed by the rest of the terms that complete the originalharmonic series. It is shown that each of these series is one convergent and the other divergent, thus obtaining the original divergent series. It is included the demonstration of the divergence of the new series, and as an extension of this decomposition of the harmonic series, a comparison is made of two subharmonic series which, despite being both divergent, differ in their value to infinity.
Fórmulas de “Trigonometría Áurea” para las funciones Seno y Coseno
Authors: Braddock Stradtmann George
Published: March 2020

En este artículo, se define una nueva constante matemática (que llamamos b), cuyas propiedades junto con las del número áureo , permiten obtener expresiones algebraicas muy sencillas para las funciones trigonométricas seno y coseno evaluadas en diferentes ángulos. Se obtuvo una sencilla expresión para el área de un pentágono regular inscrito en un círculo de radio 1. Los cálculos de las fórmulas que nos dan el valor de las funciones trigonométricas, expresadas en función de las constantes f y b, se resumen en dos cuadros al final del artículo. Los cuadros se crearon siguiendo un procedimiento análogo al utilizado por el astrónomo Ptolomeo, para hallar los valores numéricos de su famosa tabla de cuerdas, que fue documentado en el primer libro de su gran obra "El Almagesto".

Abstract

In this paper, a new mathematical constant is defined (we called it b), whose properties along with the golden number’s properties, allow us to obtain very simple algebraic expressions for the trigonometric functions sine and cosine evaluated in different angles. We obtained a simple expression for the area of a regular pentagon inscribed within a circle with radio 1. The calculations of the formulas giving us the value of the trigonometric functions, expressed as a function of the constants f and b, are summarized in two tables at the end of this paper. The tables were created following an analogous procedure as the one used by the astronomer Ptolemy, to find the numerical values of his famous table of chords, documented in the first book of his great work "The Almagest".

The role of land (as the basis and the resource of agricultural production) is the most significant among the resources of production. The ownership of land, its use, the issue of its price and value, they have been key problems of political, social, legal and economic decisions. There were theoretical and practical experts throughout the world, and we intensively have to deal with the issue of land evaluation. In our research using empirical data collection and statistical methods, we examined not only the factors have influenced on land prices, but its effect as well.

We have proven that the „golden crown”-based land evaluation system (golden crown is a measurement unit of the quality of agricultural land in Hungary) can show the land quality differences even today, but in spite of this, the results of calculations (and also the practice) increasingly justify and urge the necessity of the introduction of a modern land evaluation system.

namese professionals graduated in Hungary, the reputation and popularity of Hungarian agricultural products and technologies, the achievements of R&D in the field of agriculture – could not be utilized from Hungarian side. Vietnam, however still preserved its socialist political establishment,but in terms of its economic development strategy and economic policy has gradually been standing on the basis of market orientation. Vietnam, with its population of ninety million shows a rapid and successful development and it means good opportunities even for Hungarian entrepreneurs.

It would be a mistake to leave these potentials unused.

Smallholder Food Marketing Behaviour

Many farmers in Africa sell their produce at low prices immediately after harvest because they need cash. They could solve temporary liquidity constraints by use of credit and store their produce to sell when prices are high. However, due to various reasons such many poor farmers have been excluded from formal financial services. In response, the informal financial market has expanded, but the question why informal credit has not facilitated storage to enable farmers benefit from intertemporal arbitrage opportunities remains largely unanswered. To answer this question, we investigate the role of informal credit markets and traders in stabilizing seasonal food crop prices. Our analysis is based on a household survey data, and in-depth interviews with key players in the informal credit market and grain traders in rural southwestern Uganda. We find that community-based self-help savings and credit associations provide credit for the majority (62%) of farmers. Informal credit still excludes the very poor and is not sufficient to enable farmers benefit from intertemporal arbitrage opportunities. Thus, poor farmers continue to ‘sell low and buy high’. The study also addresses a related fundamental aspect of food marketing: why is there no competition between traders bidding up prices after harvest and eliminating seasonal price fluctuations? We analyse traders’ costs and profit structure in the study area, and shed some light on imperfections in the grain market and the barriers that limit competition between traders. We find that grain trade is not highly competitive. High transaction costs and limited access to credit are the main barriers limiting competition. Supporting community-based self-help savings and credit associations to raise their portfolio can enable more farmers to borrow at the same time. Investing in infrastructure, organising and supporting small scale farmers to bulk their produce might lower transaction costs, promote competition and dampen price fluctuations.

Published: March 2020

The economic and political transition brought many challenges for the Hungarian agricultural sector. The break-up of large agricultural holdings had serious negative impacts on food production and on the export of agricultural products. Capital intensive profit-seeking intermediaries dominate the trading of agricultural goods that has injurious effects in terms of downward pressure on production prices and an increase in consumer prices. Cooperatives have a key role in effectively tackling the common challenges that small-scale producers have to face. More vertical integration along the food chain could contribute to providing rural employment and to an increase in living standards in rural areas. This study reviews the development, the specific features and the driving forces of modern cooperatives in Central Europe in general, and in Hungary in particular. The focus is on the integrator role of cooperatives and their future role in our globalised world.
