Functioning Hydraulic and Morphological Sustainability of River Training Works in Bangladesh

River dynamics play the most vital role in the socio-economic of the country. These rivers are highly dynamic in nature which causes extensive riverbank erosion. Active river bank erosion and bed scouring, is apprehended to change the scenario, leading to loss of limited valuable land of Bangladesh. River training is being practiced in Bangladesh since 1960s but the process is very expensive especially in the Ganges and the Jamuna Rivers. Five types of river training works were selected at different reaches. Hydro-morphological characteristics of the major rivers are being evaluated not only in engineering concepts but also in socio-economic and environmental aspects. PRA （participatory rural appraisal） tools were applied to evaluate protection safety, hydraulic and hydrological connectivity, ecological and environmental characteristics, causes of failure and social acceptability. This comparative study is being carried out for closing the gap between the modem river training works and in country experience through adaptation of research findings with a view to effectively arresting river bank erosion. Sirajganj Hardpoint, Chandpur Town Protection work and Nakalia Revetment are found to be suitable and effective. A technically suitable structure may not have good social acceptance without IWRM （integrated water resource management）.

Responsibilities and Working Mechanism of National Human Rights Education and Training Bases

On July 22, 2014, the second group of national human rights education and train- ing bases was announced,increasing the number of national bases from the previous three to a total of eight, which reflects the advancement of human rights education and ~aining in China and has far-reaching significance.

An implementation of cellular automaton model for single-line train working diagram

According to the railway transportation system＇s characteristics, a new cellular automaton model for the single- line railway system is presented in this paper. Based on this model, several simulations were done to imitate the train operation under three working diagrams. From a different angle the results show how the organization of train operation impacts on the railway carrying capacity. By using the non-parallel train working diagram the influence of fast-train on slow-train is found to be the strongest. Many slow-trains have to wait in-between neighbouring stations to let the fast-train（s） pass through first. So the slow-train will advance like a wave propagating from the departure station to the arrival station. This also resembles the situation of a highway jammed traffic flow. Furthermore, the nonuniformity of travel times between the sections also greatly limits the railway carrying capacity. After converting the nonuniform sections into the sections with uniform travel times while the total travel time is kept unchanged, all three carrying capacities are improved greatly as shown by simulation. It also shows that the cellular automaton model is an effective and feasible way to investigate the railway transportation system.

Research on Optimization of Selection of Train Passing Routes and Division of Shunting Work in Railway Hub

in this paper, a general integer prosramming model is set up, and its solution ispresented to optimize the organization of wagon flows and the determination ofthe train running route as well as division of shuntins work among stations in ahub. As application example is put forword, with some conclusions reached.

Vocational Rehabilitation after Acquired Brain Injury: A Swedish Study of Benefits and Costs

Purpose: To examine the benefits from a vocational rehabilitation program for patients suffering from Acquired Brain Injury (ABI) in terms of quality of life, and overall health. In addition, to examine the direct societal costs of healthcare interventions related to vocational rehabilitation and indirect societal costs related to production loss. Method: Identified interventions in 45 patients with ABI who were discharged from a vocational rehabilitation program between 2010 and 2011 were documented, classified and translated into costs. Expenses associated with production loss were calculated by comparing sick leave production loss at first contact with the team, with sick leave production loss at discharge. Health related QoL and overall health, was measured at first contact and at discharge by using the EQ5D. Results: For vocational rehabilitation interventions, mean costs were €6303/individual/month. At first contact with the team, mean production loss was estimated to be €4409/individual/month compared;at discharge to be €2446. QoL ratings increased from first contact to discharge, although estimated health did not change. At discharge, significant correlations were found between QoL ratings and estimated health and the extent of production loss
