The dynamic properties of ride-on beams of bridge ore loaders are investigated, both for a rod with variable mass and cross-section rigidity in time and along the span. To solve the differential equations of transverse vibrations, Fourier series and Bessel functions are used.

This study demonstrate the comparative performance evaluation of some selected commercial banks in Bangladesh by using CAMEL Rating Approach.. The study found that some conventional and Islamic bank‘s performance are very satisfactory, some bank‘s performance are on average and some are not very good. It was found that the Eastern Bank Ltd. is in top position followed by EXIM Bank Ltd. By analyzing the performance of all these banks in term of CAMEL parameters it seemed that these banks Capital adequacy, Asset quality, Management quality, Earnings quality, Liquidity Management are in satisfactory level. The study recommended thatthe bank has to increase its capital so that it become more capable to meet any financial unexpected condition then before due to credit risk, market risk and interest risk.

The bio mass energy demand in Sri Lanka has increased significantly with its developing industrial sector and especially with the tea industry. Timber plantation for fuel wood and timber is not enough meeting energy demand in Sri Lanka. While long term uncertan dependency on fossil fuels has resulted in an increasing demand for renewable energy. However, within this crucial problem in biomass energy production in Sri Lanka, selection of alternative bio Mass timber which could provide a sustainable supply of feedstock without having an impact on food security and the environment is a necessity. In this context, promote using bamboo, a perennial grass, as a potential alternative for biomass energy in Sri Lanka. Since bamboo is already growing along the riverine areas in Sri Lanka, In this research highly focused on economical characteristics of bamboo along with the Gliriceedia and multi cropping with ginger and turmeric as a economical support crop for bio mass energy issue in Sri Lanka. Further bamboo has many ecological and socioeconomic benefits; there can be several challenges in bamboo cultivation and management for bioenergy production. Bamboo plantations managed properly since the some plant species can pose a threat as an invasive species, as it can displace the surrounding native vegetation. Bamboo monocultures/intercrops with selected crops can increase the forest cover and the bio diversity to increase the carbon sequestration.

The brewing temperature will affect the organoleptic, physical, and chemical characteristics of brewing tea. The brewing time affects the dissolved material content, colour intensity, and aroma. The purpose of this study was to determine the effect of the initial brewing temperature on colour intensity and the sensory characteristics of black rice bran tea and determine the initial brewing temperature most preferred by consumers to produce black rice bran tea. The experiment in this study used a completely randomized design for colour intensity tests and organoleptic tests. The influencing factor in this research is the initial brewing temperature which consists of 5 levels, namely 60oC, 70oC, 80oC, 90oC, 100oC. The variables analyzed were colour intensity systems L*, a*, b* and sensory evaluation. The results showed that the initial temperature treatment significantly affected brightness level (L*), redness level (a*), yellowness level (b*), and the sensory test. The initial temperature treatment of 90º C is the most preferred treatment by consumers to produce brewed black rice bran tea with sensory evaluation characteristics of brightness level (L*) 46.10±0 .65, level of redness (a*) 21.19±0.10, level of yellowness (b*) 30.54±0.24 and 6.60±0.50 (like to very like).
