Online Circular Calendar

A calendar is a system to organize days for social, commercial or administrative purpose. Many calendar systems are available today. The calendar system helps the user in scheduling his/her events or tasks over a time period. This period may be an hour, a day, or even months. Due to increase in user’s activities, events that need to be scheduled in the calendar grow tremendously. Moreover, there are events that occur every year which require a good visualization for mental manipulation. As a result there is a difficulty in organizing these events in the current calendar system. The main idea of this project is to provide a calendar system in which users can organize the events easily, and to close the gap between the actual software and the mental model of the users. None of the current calendar systems have the ability to manipulate and plot graphs throughout the year. The data is user dependent and can be of any sort like temperature, rainfall, stock analysis etc., Apart from this; good visualization techniques can be used for the calendar system to make the events apparent to the users. By this way user can view the overall picture of the events and will have clear idea about their events. This paper describes the implementation of such a calendar system with good visualization

Is Organic Farming an Unjustified Luxury in a World with too many hungry People?

The soaring food prices on the global markets over the past one to two years have given proponents of classical Green Revolution thinking an opportunity to renew their claims that high input agriculture based on chemical fertilizer and pesticides is the blanket solution for poor countries and farmers. This situation has also led others to question whether we should abandon all the environmental considerations in agricultural policies over the last 25 years, and relieve the regulatory burden on agriculture, and put food production in full throttle like in the good old days in the 1970s. However, as always, the solutions proposed depend on the perception of the problem. In fact, there is little evidence that just producing more food in the North will help solve the food insecurity in the South in a sustainable way. Nor is it evident that returning to subsi-dized artificial fertilizers in the South would make any significant contribution to addressing the food insecurity among those communities of the South that are currently food insecure

Organic agriculture in relation to food security of developing countries

A study was conducted to investigate the differences in farm production, input use and farm income between organic and conventional systems in three regions (Uttaranchal, Madhya Pradesh and Tamilnadu) of India. From each region, 40 organic and 40 conventional farmers were interviewed with semi structured questionnaire. The results showed that input costs were less in the organic system while either total farm yield or net margin was righter in the organic system in two of the three regions. In Tamilnadu specializing in rice production, rice yield was less under organic system while net margin did not differ signifcantly. In addition, the IFPRI-IMPACT model was used to fnd out the impact of large scale conversion to organic farming on food security of Sub-Saharan Africa. The model showed that large scale conversion to organic farming in Europe and North America will not have major impact on food security of Africa and large scale conversion in Sub-Saharan Africa will improve the local food security

Techno-economic performance analysis of biofuel production and miniature electric power generation from biomass fast pyrolysis and bio-oil upgrading

The techno-economic performance analysis of biofuel production and electric power generation from biomass fast pyrolysis and bio-oil hydroprocessing is explored through process simulation. In this work, a process model of 72 MT/day pine wood fast pyrolysis and bio-oil hydroprocessing plant was developed with rate based chemical reactions using Aspen Plus® process simulator. It was observed from simulation results that 1 kg s−1 pine wooddb generate 0.64 kg s−1 bio-oil, 0.22 kg s−1 gas and 0.14 kg s−1 char. Simulation results also show that the energy required for drying and fast pyrolysis operations can be provided from the combustion of pyrolysis by-products, mainly, char and non-condensable gas with sufficient residual energy for miniature electric power generation. The intermediate bio-oil product from the fast pyrolysis process is upgraded into gasoline and diesel via a two-stage hydrotreating process, which was implemented by a pseudo-first order reaction of lumped bio-oil species followed by the hydrocracking process in this work. Simulation results indicate that about 0.24 kg s−1 of gasoline and diesel range products and 96 W of electric power can be produced from 1 kg s−1 pine wooddb. The effect of initial biomass moisture content on the amount of electric power generated and the effect of biomass feed composition on product yields were also reported in this study. Aspen Process Economic Analyser® was used for equipment sizing and cost estimation for an nth plant and the product value was estimated from discounted cash flow analysis assuming the plant operates for 20 years at a 10% annual discount rate. Economic analysis indicates that the plant will require £16.6 million of capital investment and product value is estimated at £6.25/GGE. Furthermore, the effect of key process and economic parameters on product value and the impact of electric power generation equipment on capital cost and energy efficiency were also discussed in this study

Pedigree tool

Collecting the family history to find the inheritance of trait is the fundamental concept in human genetics. The collected information on the family can be presented in an easily readable chart called Pedigree. Hand-drawn pedigrees become difficult when there is a large collection of known individuals in the family. Hence Pedigree tool was developed which automatically creates the Ancestor tree and Descendant tree. This tool also has an option to find the unrelated individuals. Inserting individual details into the database can also be done using this tool. Thus this user-friendly java based application can help researchers and genetic counselors to investigate the genetic cause of the hereditary diseases. Discovering the genes that are involved in susceptibility to the diseases will be useful for earlier diagnosis and treatment to slow or prevent the disease

Changing Dynamics of Regional Trade and Cooperation: A Case of Japan and South Korea

Forced labour has remained a sore point in the Japan- South Korea relationship. The 2018 South Korean Supreme Court verdict on the issue of compensating Korean workers, forced by Japanese companies to work in factories and mines during World War II, has revived war-time memories in South Korea. The situation quickly escalated into a “trade war” in 2019. At a time when the security in East Asia requires Japan and South Korea to work together, a historical issue remains a lingering challenge. This article will attempt to understand the nuances of Japan-South Korea reconciliation efforts, and how the South Korean Supreme Court ruling against the Japanese Companies operating in Korea has become a political issue in both Japan and South Korea. Further, it will focus on the Japanese export control measure, regional security issue and how Covid-19 is affecting the bilateral relationship

Love in Jeevakumaran's short stories

Love is the reason why the world is alive. Animals, birds and all living beings are filled with love. It is not possible to avoid love and bring this world into the imagination. Love stirs everyone to the point of saying that there are no poets who do not sing about love, and there are no creators who do not write about it. Every creator writes this love according to his opinion or on the basis of recording the reality as it is. Thus, this article seeks to explore what accounts of love have been given in his works by V. Jeevakumaran of Denmark

Development Of Nanostructured Austempered Ductile Cast Iron

Austempered Ductile Cast Iron is emerging as an important engineering materials in recent years because of its excellent combination of mechanical properties such as high strength with good ductility, good fatigue strength and fracture toughness together with excellent wear resistance. These combinations of properties are achieved by the microstructure consisting of acicular ferrite and high carbon austenite. Refining of the ausferritic microstructure will further enhance the mechanical properties of ADI and the presence of proeutectoid ferrite in the microstructure will considerably improve the ductility of the material. Thus, the focus of this investigation was to develop nanostructured austempered ductile cast iron (ADI) consisting of proeutectoid ferrite, bainitic ferrite and high carbon austenite and to determine its microstructure-property relationships. Compact tension and cylindrical tensile test samples were prepared as per ASTM standards, subjected to various heat treatments and the mechanical tests including the tensile tests, plane strain fracture toughness tests, hardness tests were performed as per ASTM standards. Microstructures were characterized by optical metallography, X-ray diffraction, SEM and TEM. Nanostructured ADI was achieved by a unique heat treatment consisting of austenitization at a high temperature and subsequent plastic deformation at the same austenitizing temperature followed by austempering. The investigation also examined the effect of cryogenic treatment, effect of intercritical austenitizing followed by single and two step austempering, effect of high temperature plastic deformation on the microstructure and mechanical properties of the low alloyed ductile cast iron. The mechanical and thermal stability of the austenite was also investigated. An analytical model has been developed to understand the crack growth process associated with the stress induced transformation of retained austenite to martensite

Language style and reformist ideas in Anna's work

One of the leaders of the Dravidian movement, C.N. Annathurai, also known as Arignar Anna, was the general secretary of the Dravida Munnetra Kazhagam. He used creative works such as drama, novel, etc., as a tool to convey the principles of his movement to the people, to eradicate superstitions in the people and to inculcate reason. Thus, in his short novel Scars, this article examines how he has applied social reform ideas, ideals, feminist principles, rationalism, etc

Economic thoughts found in Pattinapalai

If the people living in a country live happily and contentedly, it means that there is good economic prosperity there. If the economy is prosperous, then they should have had the best thinking and planning in earning and spending the economy. As far as the Tamils of the Sangam age are concerned, the economic ideas have been explained more often by living and showing them than by speaking alone. Economic ideas are embedded in the way they lived. Therefore, if we study the way of life of the Tamils of the Sangam age, we will find out the way of life in which they lived with economic thought and the economic thought which was the basis for it. Thus, the purpose of this article is to bring out the ideas on the economy based on the way of life of the Tamils found in the Pattinapalai book, which is included in the Sangam literature, Pathupaattu
