an elliptical tank cross-section is formulated to explore and optimization method, based on a real-coded genetic algorithm to enhance the roll stability limit of a tank vehicle. a shape genetic algorithm optimization problem is applied to minimize the overturning moment imposed on the vehicle due to c.g. height of the liquid load, and lateral acceleration and cargo load shift . the minimization...

This study was carried out to evaluate the effect of two probiotic Bacillus spp. (RM10 and BFAR9) on growth, length-weight relationship (LWR), condition factor (k) Nile tilapia (Oreochromis niloticus). For this, one hundred thirty-five fingerlings (1.12±0.08 g weight 1.26±0.15 cm length) were divided into three groups (Control, RM10, distributed nine circular concrete tanks. The fish fed with c...

A 1995 outbreak of dengue haemorrhagic fever (DHF) occurred on Samui Island in Thailand with an incidence of almost 500 cases/100,000 population. To find and develop effective strategies to control this disease through cost-effective vector control programs, entomological studies were carried out on the island between 1996 and 1998. There were two species of DHF vectors, Aedes aegypti and Ae. a...

In the article, authors present results of a study flat reinforced concrete beamless floor an existing building. The experiment consisted loading slab in span with water tanks. There were 15 stages total, on average 4 kN. During experiment, data was obtained relative deformations and reinforcement support. Also, observations growth vertical cracks introduced.

The construction industry generates a considerable amount of waste. Faced with this undesirable situation, the ready-mix concrete sector, in particular, has invested energy and resources into reusing its own waste in its production process as it works towards the goal of more sustainable construction. This study examines the feasibility of incorporating two types of concrete waste, which curren...

The susceptibility of structural concrete to early-age cracking depends on material composition, methods of processing, structural boundary conditions, and a variety of environmental factors. Computational modeling offers a means for identifying primary factors and strategies for reducing cracking potential. Herein, lattice models are shown to be adept at simulating the thermal-hygral-mechanica...
