This study pertains to direction of exports direction of major agricultural commodities viz., rice, maize, bengal gram, chillies and cotton from India. In the ensuing next decade during 21st century, India is likely to witness changes in the export pattern of these commodities due to both internal and external constraints. One of the major internal constraints is mounting cost of production. Similarly, one of the most important external constraints include excessive subsidization by importing countries that makes Indian commodities less competitive in the international market. So, the important research question is to analyse the direction of exports of major agricultural commodities from India during post-WTO regime. The dynamic nature of trade pattern of the selected commodities was analyzed by employing the first order Markov process by examining gains and losses in respect of export shares of major Indian agricultural commodities to different countries. During the post-WTO regime, it was found that Saudi Arabia for rice, Bangladesh for maize, Pakistan for bengal gram, Malaysia for (dry) chillies, China, mainland for cotton are the loyal destinations for the commodities. The increasing demand for the selected commodities in countries like Saudi Arabia, Côte d'Ivoire for rice; Malaysia for maize; Pakistan and Algeria for Bengal gram; USA and Sri Lanka for (dry) chillies and Vietnam, Pakistan and Indonesia for cotton need to be explored for augmenting the exports. In order to achieve this goal, it is essential that consumer preferences in newer markets, market intelligence and impediments for augmenting exports need to be researched. It is also high time to analyze the export competitiveness of selected commodities across these importing countries.

It is important to understand the factors influencing the temporal and spatial variability of water quality in order to establish an effective customized management strategy for contaminated aquatic ecosystems. In this study, the spatial diversity of the 5-year (2015 - 2019) average total phosphorus (TP) concentration observed in 40 Total Maximum Daily Loads unit-basins in the Nakdong River watershed was analyzed using 50 predictive variables of watershed characteristics, climate characteristics, land use characteristics, and soil characteristics. Cross-correlation analysis, a two-stage exhaustive search approach, and Bayesian inference were applied to identify predictors that best matched the time-averaged TP. The predictors that were finally identified included watershed altitude, precipitation in fall, precipitation in winter, residential area, public facilities area, paddy field, soil available phosphate, soil magnesium, soil available silicic acid, and soil potassium. Among them, it was found that the most influential factors for the spatial difference of TP were watershed altitude in watershed characteristics, public facilities area in land use characteristics, and soil available silicic acid in soil characteristics. This means that artificial factors have a great influence on the spatial variability of TP. It is expected that the proposed statistical modeling approach can be applied to the identification of major factors affecting the spatial variability of the temporal average state of various water quality parameters.

Properties of slag cement that contained 50 wt% of blast furnace slag were studied when replaced blast furnace slag powder with electric arc furnace slag powder. Electric arc furnace slag was aged for about 2 months in the air by being crushed to be 1-3 mm in size. As a result of the experiment, it was proven that the water content for obtaining the same consistency became decreased as slag is replaced with electric arc furnace slag instead of blast furnace slag. Also, the workability of mortar increased about 30% at the same ratio of water to binder when blast furnace slag was completely replaced with electric arc furnace slag. The compressive strength of mortar on the 28 days increased when a slag replacement rate became 10 wt%, however, it rather decreased when the slag replacement rate exceeded 10 wt%. The heat of hydration became higher for the first 14 h in case of the replacement of slag cement by electric arc furnace slag. Yet, it decreased when 14 h had passed. Therefore, when all blast furnace slag was replaced with electric arc furnace slag, about 15 cal/g heat of hydration decreased when it passed about 72 h.

Climate change is one of the major issues in both the developed and developing world. Greenhouse gas (GHG) emission is one of the implications for climate change. It is increasing rapidly. Although the emission is much less when compared to the rest of the world, Ethiopia has also faced this global issue. The major source for GHG emission in Ethiopia is agriculture. Therefore, the agriculture sector has to be given more attention in Ethiopia. To overcome the problem, Climate-Resilient Green Economy (CRGE) strategy has been initiated. One way of executing this target is to create a sustainable and environmentally friendly pathway to use agricultural byproducts. Sugarcane is one of the major plants in Ethiopia. Its byproducts are bagasse, molasses, and press mud. Since it is a waste product, it is economical and creates a sustainable and green environment by reducing GHG emissions. Sugarcane byproducts have versatile applications like as fuel, as cement replacing material, as a mitigation for expansive soils, as biosorbent for the treatment of water and wastewater and also as a wood material. However, Ethiopia has not used this byproduct massively as it is readily available. This paper reviews the possible applications of sugarcane byproducts to mitigate climate change.

It is common that several kind of claims between the parties are arising in carrying out international construction works. Therefore, it is very important for them to settle the claims effectively in order to get expected profits and purposes in international construction works. In this article, the author have studied on the procedures and contents on the settlement of claims between the parties based on the FIDIC contracts for major works which are newly prepared in 1999 by FIDIC. Especially, the arbitration clause in the FIDIC contracts for major works attempts to deal with a number of complex contractual and legal matters, sometimes in a very harsh way, e.g. by cutting off a party's rights. It has never been an easy clause to understand or to observe. Nevertheless, the author hopes he has been able in this article to clarify for the reader some of the issues raised by it. I'd like to suggest that our overseas construction companies refer to the FIDIC contracts for major works(especially article 20 : claims, disputes and arbitration) directly or indirectly for their contract of international construction works with overseas employers.
