Structure-thermal expansivity relation for isotropic polyoxymethylene sheets
(
John Wiley & Sons, Ltd.
, 1994 , Article)
A detailed parametric mapping analysis of the thermal expansion coefficient for isotropic polyoxymethylene is presented. The molecular composite model has been computerized to investigate the variation of the thermal ...
Thermal dimensional stability of isotropic polyoxymethylene
(
John Wiley & Sons, Ltd.
, 1991 , Article)
A parametric mapping analysis of the effect of various structural and morphological parameters on the thermal dimensional stability of polyoxymethylene is highlighted. The molecular composites model is found to describe ...
Ultrasonic and thermal properties of γ-irradiated low-density polyethylene
(
John Wiley & Sons, Inc.
, 1993 , Article)
The ultrasonic pulse-echo technique and differential thermal analysis were utilized to characterize and to monitor the effect of ?-irradiation on the sonic modulus and the heat effect of low-density polyethylene. The sonic ...
Dynamic behavior of mixer-settlers
(
Wiley Subscription Services, Inc., A Wiley Company
, 1990 , Article)
A mathematical model has been developed to simulate and predict the dynamic behavior of liquid extraction counter current operations in mixer-settler units. Murphree efficiency has been included in the model. The behavior ...
Analysis of the thermal expansion behavior of oriented polyoxymethylene sheets
(
Wiley Subscription Services, Inc., A Wiley Company
, 1996 , Article)
The applicability of the molecular composite model is extended to include the analysis of the thermal expansion behavior of oriented (anisotropic) polyoxymethylene. The model accounts for changes in the morphological and ...
Economic And Thermal Performance Of Thermostone In Qatar
(
Qatar University
, 1996 , Article)
This paper is concerned with the performance characteristics of thermostone as a building material, and their comparison with those of hollow concrete blocks. Carrier Advanced Load Program (E20-II) was used to estimate the ...
A Spreadsheet Teaching Tool For Analysis Of Pipe Networks
(
Qatar University
, 1997 , Article)
Spreadsheets are used widely in engineering to perform several analysis and design calculations. They are also very attractive as educational tools due to their flexibility and efficiency. This paper demonstrates the use ...
Performance of Greenhouses in The Arabian Gulf
(
Qatar University
, 1990 , Article)
This work is devoted to the gaining of insight into the operation of environmentally controlled greenhouse in hot and humid climates. Field data inside and outside the greenhouse, namely: solar radiation, dry and wet bulb ...
Solidification Of Steel Billets In Continuous Casting
(
Qatar University
, 1991 , Article)
For practical operation, it is necessary to know how the solidification of liquid steel progresses i.e. when and where a strand has completely solidified. Decisions on, the casting speed, the spray water flow rates and ...
Performance Evaluation Of A Msf Desalination Plant In Qatar
(
Qatar University
, 1992 , Article)
In this paper, an assessment of the performance of one of the multistage flash (MSF) desalination units operating in conjunction with the gas-turbine cogenera-tion power plant in Qatar is carried out under different operating ...
