Mô phỏng số đánh giá ảnh hưởng của xoắn đến khoá chống cắt trong cầu dầm lắp ghép phân đoạn
Authors: Nguyễn Đắc Đức , Nguyễn Ngọc Long , Trần Đức Nhiệm
Published: March 2020

Vị trí mối nối trong cầu dầm lắp ghép phân đoạn ngoài nhiệm vụ nối ghép các đốt
dầm thành kết cấu hoàn chỉnh thì phải đảm bảo truyền lực giữa các đốt dầm như lực dọc, mô
men uốn, mô men xoắn, lực cắt...Đặc trưng của dầm lắp ghép phân đoạn sử dụng mối nối khô
là tại vị trí mối nối không có cốt thép thường do đó cốt thép dự ứng lực đóng vai trò chịu mô
men uốn, đối với lực cắt sẽ sinh ra ứng suất tiếp tại vị trí mối nối, ứng suất tiếp này sẽ do khoá
chống cắt và ma sát tiếp xúc của bề mặt bê tông tại vị trí mối nối đảm nhiệm. Khi tải trọng đặt
lệch tâm hay có tác động gây ra mô men xoắn tại vị trí mối nối, mô men xoắn này sẽ sinh ra
ứng suất tiếp phụ thêm, do đó việc đánh giá ảnh hưởng của mô men xoắn đến khả năng chịu
lực của mối nối nói chung và khoá chống cắt nói riêng là cần thiết nhằm đảm bảo việc thiết kế
mối nối là an toàn. Bài báo đánh giá ảnh hưởng của mô men xoắn đến ứng suất tại khóa chống
cắt của mối nối thông qua tính toán mô phỏng nhằm giúp cho việc tính toán khả năng chịu lực
của khóa chống cắt an toàn, phù hợp với điều kiện làm việc của mối nối.

A proposal of methodology to analyze platoon dispersion at signalized crosswalk considering pedestrian demand and crosswalk length
Authors: Chu Tien Dung
Published: March 2020

Understanding pedestrian platoon dispersion at signalized crosswalk is essential not only for improving pedestrian safety but also for estimating pedestrian crossing time requirement. This paper proposed platoon dispersion ratio (PDR) as an index to analyse the effects pedestrian demand and crosswalk length upon pedestrian platoon dispersion at signalized crosswalk. The result shows that the heavier pedestrian demand usually corresponds to greater platoon dispersion. Regarding the influence of crosswalk length, it is revealed that the dispersion tends to increase as the crosswalk length increases

Published: March 2020

En este artículo, trataremos de dar un significado a la complejidad de la era en la que nos encontramos, utilizando como modelo de referencia, el logro más importante de gobernanza policéntrica que la humanidad ha podido concebir en el Antropoceno, es decir, la Convención Marco de Naciones Unidas de Cambio Climático (CMNUCC) y sus múltiples instancias orgánicas, para articular ciencia, política y economía. Postulamos que, en su corta existencia, la Convención ha pasado por tres fases principales, cada una de las cuales convoca principalmente, a uno de los diferentes grupos de ciencias en las que tradicionalmente consideramos dividido el conocimiento científico: ciencias básicas, ciencias sociales y ciencias humanas.En este sentido, consideramos que el presente escrito es una respuesta consistente con el llamado de los tiempos, caracterizado por la búsqueda humanista de significado, expresada a través de las épocas en el concepto de "espíritu", en cuanto definición que rescata los valores de una concepción sistémica, holística y dialógica.La transición a fuentes de Energías Renovables No Convencionales (ERNC) marca un punto de inflexión en el que las humanidades o ciencias humanas, permiten tomar conciencia de la realidad científica del desastre climático causado por el modo de producción capitalista y la magnitud sistémica de su alcance. El establecer propuestas para modificaciones de tal magnitud reverbera en la dimensión espiritual.El carácter universal de las tres plataformas lanzadas en 2015 por la ONU: Riesgo y Desastres de Sendai, Objetivos de Desarrollo Sostenible y Acuerdos de París, así como la introducción más reciente de los Diálogos de Talanoa (COP 23, 2017) -aquí presentados y referidos brevemente-, parecen corroborar el análisis y proyecciones de nuestra ponencia.Palabras clave: cambio climático, UNFCC, IPCC, Humanidades, Diálogos de Talanoa, Acuerdos de París.
Ensayo sobre la realidad socioecológica: No alcanza para todos
Authors: Borner Joachim
Published: March 2020

The essay starts of with a personal reflection of a senior researcher who has been investigating on global environmental change since the early beginnings of his career. It then moves to an analysis of the present challenges of humanity and the predominant narratives, which seem to steer our actions and hinder us from mitigating climate change and for staying within the planetary boundaries. Also it points out the role of hyperobjects, such as climate change, which are too big to grasp and too abstract to feel or imagine. In the discussion it opens up the imperative of creating new narratives to tackle the above issues, and reflects on the role of storytelling / future narrations to reach this goal of utmost importance for our planet's - for humanity's sake.
Normalización Filosófica: entre filosofía y cultura
Authors: Ahumada Aldo
Published: March 2020

La realización de este trabajo busca un doble propósito: por un lado, analizar lo que Francisco Romero (1891-1962) ha denominado normalización de la filosofía, es decir, el proceso de instalación de los estudios filosóficos como disciplina independiente en América Latina; y sus diferentes interpretaciones o lecturas que se le ha realizado al concepto, las que a grandes rasgos hemos dividido en dos vertientes (normalización como clausura y como reafirmación disciplinar). Por otro, utilizarla categoría romeriana para identificar qué elementos de la cultura comprobarían que la filosofía se convierte en una más de las expresiones culturales de los distintos países latinoamericanos (rasgo distintivo de la normalización). Para ello, hemos escogido las ideas o imaginarios de Chile y América Latina que circulaban en diversos filósofos chilenos de la época (primera mitad del siglo XX), las cuales también se reflejarían en otras expresiones artísticas y disciplinas desarrolladas en el país.

Esto, para estudiar su teoría del conocimiento histórico como una de las bases principales de la metodología de la Escuela de los conceptos fundamentales de Reinhart Koselleck, pudiendo así mostrar en este primer análisis la importancia y significación de los aportes gadamerianos para este método y el respectivo abordaje de la historia. Partiremos de las razones que presenta el propio Gadamer para entender su teoría de la experiencia hermeneútica y lo que significa ésta. Se desarrollará luego las implicaciones que esto tenga con el lenguaje y los conceptos. Y por último, señalaremos su aporte para la construcción del método de la historia conceptual.
El Tren Interurbano México-Toluca, un proyecto que atenta en contra del medio ambiente y los derechos humanos en La Marquesa, México
Authors: García Galván Marta
Published: March 2020

El Tren Interurbano México-Toluca (TIMT) es un proyecto que conectará el Valle de Toluca y la Zona Poniente de la Ciudad de México mediante un sistema de transporte moderno, considerado primero en su género en Latinoamérica, que pretende igualar el nivel de transporte de pasajeros al de ciudades como Nueva York, Chicago, Madrid, Londres, Ámsterdam y otras grandes ciudades interconectadas por vía ferroviaria. Sin embargo, para su construcción ha devastado Áreas Naturales Protegidas como El Parque Nacional Insurgente Miguel Hidalgo y Costilla conocido popularmente como La Marquesa, considerado éste el único pulmón verde que queda entre el Distrito Federal y Toluca en el centro de México. Dicha obra ha ocasionando daños irreversibles en materia ambiental, económica, social y política que ha traído consigo manifestaciones y descontentos de los pobladores con el gobierno encabezado por el Presidente Enrique Peña Nieto, quien lejos de dialogar y solucionar sus problemas ha enviado a la fuerza pública para custodiar el tramo de construcción en esta zona tratando de intimidar a la población y en vez de generar desarrollo para sus comunidades, ha traído consigo el incremento de la pobreza y marginación para las generaciones presentes y futuras de la región, ya que es una zona que se dedica principalmente al turismo y al comercio. Estas dos actividades se han visto mermadas por la construcción de dicha obra y por la presencia de elementos de la fuerza pública. Por ello, en este artículo se pretende evidenciar el daño ocasionado a las estructuras ambientales, económicas, sociales y políticas de la gente de La Marquesa por la construcción del TIMT, para lo cual, se recopiló información relevante a través de entrevistas con informantes clave mediante el método etnográfico desde una perspectiva de la geografía humana y poder hacer un análisis del impacto que tienen los megaproyectos sobre el medio ambiente y los pueblos originarios.

Boron-Enabled Geometric Isomerization of Small Alkene Fragments via Selective Energy Transfer Catalysis
Authors: Molloy John James , Schäfers Michael , Wienhold Max , Morack Tobias , Daniliuc Constantin G. , Gilmour Ryan
Published: March 2020

The mammalian visual cycle epitomizes the importance of complex polyenes in biology. However, isomerization-based strategies to enable the sterodivergent construction of these important biomolecules from geometrically defined alkene linchpins remain conspicuously underdeveloped. Mitigating the thermodynamic constraints inherent to isomerization is further frustrated by the considerations of atom efficiency in idealized low molecular precursors. Herein, we report a general ambiphilic C3 scaffold that can be isomerized and bi-directionally extended. Predicated on highly efficient triplet energy transfer, the selective isomerization of β-15 borylacrylates is contingent on the participation of the boron p-orbital in the substrate chromophore. Rotation of the C(sp2)-B bond by 90° in the product renders re-excitation inefficient and endows directionality. This subtle stereoelectronic gating mechanism enables the stereocontrolled syntheses of well-defined retinoic acid derivatives.

Authors: Jain Dhiraj , Ranawat Khushboo
Published: March 2020

Different investors have different choices at different stages This paper examines the association of demographic factors on investment choices. The differences among the different genders were found to be significant for post office schemes, real estate, gold/commodities and shares/equity. The chi-square test shows that investors with higher income group prefer to invest in real estate and females prefer to invest in gold/commodities. The study also reveals that females were conservative while investing and males were aggressive. Most of the investors consult their family members for taking investing decision and invest for the period of 3-5 years. Most of the investors invested their money for the safety and growth of money. There is no association of income, age, gender, occupation on the percentage of income and investors wants to save for the future requirements, but there is significant relationship between qualification and percentage of income save for future requirements. But demographic factors does not effect the investment period. This study shows that there is association of demographic profiles and personality type of the investors with investment choice.

Authors: S KANAKA , M CHINADURAI
Published: March 2020

Recent developments in the international trade scenario and corresponding alterations in India’s foreign trade policies have depicted far reaching implications for India’s agricultural sector in general and agricultural exports in particular. The present study has ascertained the changes in comparative advantage status of India’s major agricultural exports during the postreforms period (1994-95 to 2008-09). India had enjoyed a comparative advantage in tea exports but had depicted a declining trend over the years. A similar pattern had been observed in coffee exports also, where India had been found losing its comparative advantage to other world coffee exporters. An unstable pattern of comparative advantage had been observed in the case of rice exports with intermittent ups and downs in the status. A gradual decline in India’s comparative advantage had been depicted for exports of sugar and cashew also.As opposed to other commodities, India had strengthened its position in the global markets in exports of Ground nut. But as far as the exports of fresh fruits and fresh vegetables are concerned, India cannot boast to have a comparative advantage. India has been found losing out its comparative advantage in export of some of the agricultural commodities to world during the period after economic reforms.

Banks in equity market - a risk analysis
Authors: K S Nemavathi , A Ashraf Ali
Published: March 2020

Equity market is often considered as the main engine driving the economy. In emerging countries, equity market plays a vital role in economic development. Many emerging markets, firms would need large quantum of fund to expand and be able to pursue the prevalent high growth rates. Equity market is the only liquid financial market in many emerging countries and hence its role in economic development cannot be overemphasized.In addition, all over the world, financial markets are getting less insular. The investors in developed countries are seeking investment opportunities beyond the confines of their domestic economy to enhance return and diversify risks. The investment in stock involves many risks. The investors have to carry analysis before investing in any stocks. Most of the investors are unaware about the analysis to be carried out before investing. This study involves analysis of earnings per share, price to earnings and analysis of risk through beta value, of the banks in equity market. Technical analysis helps the investor to know whether the stock is in over sold region or over bought region and to find any trend reversals. Based on these analysis investor can make buy or sell decision. The researcher concludes that the maximum return is based on the maximum risk in which the investor is going to face.

A study on construction of optimum portfolio with reference to the sharpe index model
Authors: D Maheswara Reddy
Published: March 2020

This research aims at constructing an optimal portfolio that maximizes the overall return andminimizes the risk associated with the individual stocks using the Sharpe Single Index Model. The studyincludes 25 stocks from five different sectors. Only the secondary data for the past five years (2007-08 to2011-2012) are used in the study. The final portfolio thus constructed includes stocks from more than onesector. Thus even if some of the sectors do not perform well as expected, it will be compensated by the excessreturns from the other sectors that exceed the expectation. This is how risk is diversified .This method ofconstruction of optimal portfolio is very effective and convenient as revision of the optimal portfolio can be anongoing exercise. The existence of a cut-off rate (Ci) is also extremely useful because most new stocks thathave an excess return-to beta ratio above the cut-off rate (Ci) can be included in the optimal portfolio. Thusthis study helps the investors to minimize risk and maximize the return on their investment.

The inclusion of fishery subsector as one of the priority subsectors in the agricultural transformation plan of Nigeria stems from the increasing demand-supply gap for fish; which continues to constitute a colossal loss of foreign exchange in Nigeria. In view of the foregoing, this study was carried to examine the programs of the fishery subsector transformation plan in the achievement of self-sufficiency in fish production which is the principal goal of the fisherysubsector transformation plan. Secondary data were employed in this study. Despite the laudable programs of the fishery transformation plan namely: (i) fish farm estate development program (ii) fish seeds and feed mill development program (iii) fish pen and cage culture development program(iv) fish post-harvest management and marketing program, the exclusion of fishery extension program in the programs of the fishery transformation plan was identified as a major weakness of the fishery transformation plan that could mar the achievement of the goal of achieving selfsufficiency in fish production.
