Urdu Dissertations of Islamic Studies on Semitic Religions (MPhil, PhD) in Pakistani Universities: An Index and Bibliometric Review Study of religions or Comparative Religions is a globally significance subject. Pakistan is also resourceful in this field. In many universities, there are special departments on this valuable subject. It is taught as compulsory course at BS & MA level in the departments of Isalmic studies in all universities. In many universities it’s also taught at MPhil and PhD level, some of them have produced hundreds of MS and PhDs dissertations on this subject. Due to its importance, it was a dire need to review and compile the titles of theses and dissertations, which are produced from the universities on the subject. In this study, efforts are made to review and compile a comprehensive index of such theses at MPhil and PhD level from Pakistani universities with statistical analysis. Due to its huge amount, the data is divided into two major types, Semitic and non-Semitic religions. The current study covers only Semitic/ Revealed and related topics. The word Semitic refers to the race of the son of Prophet Noah (A.S) or the areas where this race was spread and grew. Semitic Religions consists of; Judaism, Christianity and Islam. In this study, Biblometric approach is adopted with mix method approach. Total 393 theses of Islamic Studies on Semitic Religions are compiled and statistically evaluated in this paper. The study concludes that a good deal of literature and dissertations are available in Pakistani universities on Comparative Religions and Interfaith Studies. It is recommended that contents of theses should be analyzed for improvement of the Study of Religions in Pakistan

Mass Transfer in a Turbulent Contact Absorber

Vast amount of discrepancies are found in literature reporting the hydrodynamic and mass transfer characteristics of the turbulent contact absorbers. Most of the literature available in this regard is for small diameter columns having wall effects. Therefore hydrodynamic and mass transfer characteristics of turbulent contact absorbers have been studied in a relatively large scale, 44.7 cm diameter Perspex column so that there are no wall effects. The data reported can now be used in the designing of these absorbers. Efforts have also been made to point out the reasons of discrepancies in the reported literature. Dimensionless correlations have been developed from the data obtained in this study based on the criteria that the ratio of the column diameter to packing diameter should be greater than 10, the column diameter should be greater than 15 cm, grid free area should be greater than 70%, the ratio of static bed height to column diameter should be less than 1 and the contributions of the gas and liquid distributors should be accounted for. The correlations developed were used to simulate the data of the earlier workers, which shows that the data of those workers who have fulfilled the above criteria, their data can also be represented with in ±30% error band, using the correlations developed in this study. To develop these correlations, necessary detailed pressure drop, liquid holdup, expanded bed height and the volumetric gas film mass transfer coefficients data was obtained in this study. To do this the variation of packing diameter (25mm, 38mm and 45mm), apparent packing density (160, 270, 354, 442, 547 kg/m3) and static bed height (15cm, 25cm and 35 cm) were studied. Gas and liquid velocities in the range of 1.8 to 3.6 m/s and 0 to 0.012 m/s were used respectively. For the hydrodynamic study water and air were used as working fluids. For the mass transfer coefficients the absorber was used in an adiabatic humidification mode. Violations of one or more of the above mentioned criteria are the main reasons for the vast amount of discrepancies in the literature data. These discrepancies fall within the experimental errors, only in the reported literature which has explicitly taken into consideration of the effect of gas and liquid distributors. It is also shown that all the reported data can be represented in a dimensionless form
