Sediment Transportation

Worldwide the processes of erosion, transport and sedimentation have a significant social, economic and environmental impact. In the past decade the most important external factor that has significantly increased the erosion and sediment process is the human factor throughout its daily activities. The changes of land cover and use, the intensive deforestation, urbanization and infrastructure development, sand extraction from river beds alter the natural watercourse and thus leading to erosion, sediment transportation and finally to the silting of rivers and reservoirs. The process of erosion and sedimentation occurs, among other areas, in the hydro-technical constructions with significant effects. In the next 30 years it’s expected to lose more than 50% of the storage capacity of the reservoirs in the world due to the silting phenomenon. The control and monitor of the sediment dynamics represents a critical component in the sustainable management of water resources. Also the understanding of the involved phenomena is essential in order to develop solution for reducing the sediment and erosion that occur and adopt measures to extend the life of the reservoirs. This paper taps the solution of mathematical modelling using dedicated software in order to establish the morphological changes that occur in Ogrezeni-Crivina reservoir, located on the river Arges.

Purpose Fracture properties depend on the type of material, method of testing and type of specimen. The purpose of this paper is to evaluate fracture properties by adopting a stable test method, i.e., wedge split test. Design/methodology/approach Coarse aggregate of three different sizes (20 mm, 16 mm and 12.5 mm), three ratios of coarse aggregate, fine aggregate (CA:FA) (50:50, 45:55, 40:60), presence of steel fibers, and specimens without and with guide notch were chosen as parameters of the study. Findings Load-crack mouth opening displacement curves indicate that for both fibrous and non-fibrous mixes, higher volume of aggregate and higher size of coarse aggregate have high fracture energy. Originality/value For all volumes of coarse aggregate, it was noticed that specimens with 12.5 mm aggregate size achieved highest peak load and abrupt drop post-peak. The decrease in coarseness of internal structure of concrete (λ) resulted in the increase of fracture energy.

Development Perspective

For the empowerment of women several international meetings, conferences and seminars have been taking place globally. Consequently, women are becoming stronger in social, economic, and political sectors. The numbers of women state heads have revealed that internationally women are being empowered politically. Women’s struggle in Nepal has also brought a remarkable change in establishing women rights in social, economic, and political spheres. After democratic restoration, few efforts have been made for their empowerment. Still the Human Development index of women is not so encouraging. However, they have been involved in multi sectoral activities such as household economy, environmental conservation, social functions, and infrastructure development. After 1990, political parties have involved women in their political organizations and have provided opportunities to be elected and nominated in the national legislature, executive and judiciary. Few of them have already got chances to be Minister and Member of Parliament.Similarly, women have been working as District Development or Village Development Committee chairperson. In the inaccessible remote areas still they are not much empowered and their involvement is less. It is necessary to make them empowered.

A vast array of knowledge has been accumulated on the effect of service quality on customer satisfaction, particularly with a large number of studies over the past few years. However, the effect of service quality on satisfaction of service recipients in Divisional Secretariats in the Public Sector is relatively an unattended area by researchers. Hence, this study was carried out to evaluate the effect of service quality on satisfaction of service recipients of divisional secretariats. This particular organization was selected for the study as it is considered to be the most significant service provider in terms of statutory, social, economic and development in the country. A questionnaire survey and personal interviews were conducted to collect data by using the purposive sampling method. A modified questionnaire was prepared based on SERVQUAL instruments with two additional questions. A sample of 520 service recipients from 13 Divisional Secretariats in Colombo was drawn and it was represented by 40 from each division. Correlation analysis and multiple regression analysis were used to examine the relative impact of the service quality on satisfaction of service recipients. The study revealed that all the service quality attributes positively related to satisfaction of the service recipients. The findings of the study show that satisfaction of service recipients in terms of service quality has not met the expected level, which a divisional secretariat is deemed to provide for.

Marble Waste

Abstract A huge amount waste (approximately 60%) is generated during mining and processing in marble industries. Such waste can be best utilized in infrastructure development works. Coarse aggregate 75% by weight was replaced by aggregate obtained from marble mining waste. The impact of marble waste as a partial replacement for conventional coarse aggregate on the properties of concrete mixes such as workability, compressive strength, permeability, abrasion, etc. was evaluated. The test results revealed that the compressive strength was comparable to that of control concrete. Other properties such as workability of concrete increased, water absorption reduced by 17%, and resistance to abrasion was marginally increased by 2% as compared to that of control concrete. Ultrasonic pulse velocity and FTIR results show improvement in quality of concrete with crushed marble waste. From the TGA analysis it was confirmed that, aggregate produced from marble waste shows better performance under elevated temperature than that of conventional aggregates.
