Al-Amin; Akram, Abdur Rahman; Rahman, Tania Financial analysis is a logical way of inspecting the financial position of a company. It helps to measure ond realize lhe position of the company. It tries to cooperate the creditors, investors, and managers to determine the profitability of the company, to control costs, and to pay the interest and principal on its debt. Besides these, it gives the opportunity to lmow the liquidity of the company. For measuring the financial health of a business firm, there are lots of techniques available. But the Altman's Z-score has been proven to be a reliable tool across contexts. Bangladesh cement industry is a unique one because, the industry is producing a higher amount of cement than the local demand having no supply of local raw materials. The main objective of the study is to assess the fundamental financial health of this industry using Z-score model. Here, listed cement firms are considered in this study. The required information has been collectedfrom the annual reports ofthe selected companies andfrom other sources. The study revealed that four firms, Aman Cement, Crown Cement, Cemex Cement and Shah Cement are financially sound. The findings of the study can be useful for the managers to take financial decision, the stockholders to choose investment options and others to look after their interest in the concern cement manufacturers of the country.

Shafkat Bin; Siddique, Hossain; Ali, Mohammad Heat transfer characteristics for swirl /low of water in a circular pipe are studied numerically. The pipe is fitted with heat resistant vanes. The performance of this pipe is compared with that of an empty pipe under similar conditions. The three dimensional Navier-Stokes equations for incompressible Newtonian Jluid Jlow are used. This investigation reveals that the swirl Jlow increases heat transfer. The fficts ofvarious parameters such as Reynolds number, inlet pressure, twisting angle, surface heat flux, surface temperature, pipe length etc. are also studied.

A hybrid photovoltaic (PW) solar system combines simultaneous canversion of the absorbed solar radiation into electricity and heat. In this study the design of an experimental PWdual systern, both air and water circulation with modifications in the air channel is presented. A thin metallic sheet (TMS) inside the air channel and painted black ribbed surfaces at the bottom of the air channel are placed. For obsertting the variations of heat transmittance with change of the shape of the ribs four experimental setups with a Trapezoidal, a Saw tooth forward, a Saw tooth baclauard ribbed surfaces and a flat plate have been used, Natural convection is applied instead of forced convection to increase the system net electrical output & thereby the overall system fficiency. All setups are of the same capacity, projected area and water heat extraction method and average depth. Performance study is carried out during the months of March to June, 2012 at I(JT campus, Gazipur, Bangladesh. Significant performance has been obtained with the above stated modifications. Natural convection is allowed to take place instead of fluid conyection. Results obtained in this study have been compared with available information in the literature.

Spirality is a dimensional distortion in circular knitted fabrics and has an obvious influence on the aesthetic and functional performance. Shrinkage is the process in which a fabric becomes smaller than its original size while washing and drying. This study explicitly determined the theoretically approach of the causes and remedies of spirality and shrinkage and the main dffirence between tumble and line drying. The tumble drying was more responsible for shrinkage contrary to the line drying. Among the samples the full feeder lycra single jersey shows the best result in shrinkage and spirality and double pique shows the worst result due lo more tuck loop in its structure. Finally, this study illustrated that line drying was the best for using the garments with assured quality and dimensional stability.
