EXPERIMENTAL STUDY OF HYBRID LIQUID DESICCANT BASED VAPOR COMPRESSION COOLING SYSTEM

In the kingdom of Saudi Arabia, a vast amount of energy is used for air-conditioning and this paper describes a new approach to air conditioning. In the proposed hybrid cooling system, liquid desiccant is used to remove the latent load and the conventional vapor-compression system is used to provide sensible cooling only. In this experimental study, calcium chloride solution is used as the desiccant to dehumidify the air. Gauze-type structured packing towers are used for the dehumidification of air and also for regeneration of the weak desiccant. The designed packed bed dehumidifier and the regenerator are combined with a 5-ton capacity vapor compression system along with the heat recovery units. This paper presents results from a detailed experimental investigation of the heat and mass transfer in a structured packing dehumidifier and regenerator under a variety of operating conditions. In the present study, for the sake of comparison between hybrid and conventional cooling systems, the COP for the cooling system is defined as the heat removed from the space to be cooled divided by energy input for the cooling system. Three different modes of regeneration are considered for the hybrid cooling system and the COP values are compared with conventional vapor compression system. Results show that the ratio of the outlet-to-inlet absolute humidity reaches a steady state value of about 0.6 and the temperature of air decreased from 48 to 38o C in the dehumidifier of the hybrid system. Moreover, it is found that hybrid cooling system provides higher COP compared with conventional system

Cytotoxic effect of 2,3-disubstituted chromanones in human cancer cell lines

173-175Four different synthetic compounds [3-aryl-2-(3- pyridyl)chromanones) were prepared and screened for cytotoxicity against a panel of 29 human cancer cell lines in five different concentrations separately. All compounds displayed cytotoxicity against cancer cell lines and one of them possessed cell type selectivity also

Synthesis and characterization and anti-inflammatory and antibacterial evaluation of 3-arylidene-7-methoxychroman-4-ones

1202-12073-Arylidene-7-methoxychroman-4-ones 3a-k have been prepared from 7-methoxy-chroman-4-one 1 and heterocyclic aldehydes 2 and have been evaluated for anti-inflammatory and antibacterial activities. All of them have registered moderate anti-inflammatory and antibacterial activities

Educational acculturation and academic integrity: Outcomes of an intervention subject for international postgraduate public health students

This paper discusses a case study of a subject developed and implemented in a post-graduate public health program at the University of Wollongong that aims to foster the development of student academic integrity and related skills as students are introduced to a new educational culture. The subject adopts a formative, task-based approach where written and oral pedagogic tasks focus on various components of a final written assessment task. The subject was collaboratively developed by faculty and learning development staff and, in addition to the subject co-ordinator, its implementation is supported by library and learning development staff, as well as a tutor who is a graduate of the course. The majority of students enrolled in this course are recent health professional graduates from South Asia. In the light of recent arguments for awareness of cultural diversity in universities (e.g., McGowan, 2005a, 2005b; Chanock, 2003; East, 2006) and in the context of program evaluation, we report on the learning outcomes achieved by one group of newly-arrived South Asian students in the communication and academic integrity intervention subject. The paper draws on and aims to extend research into South Asian students’ understanding and development of academic integrity in Australian tertiary institutions (e.g., Handa & Power, 2005)
