A GIS Based University’s Campus Evacuation Plan in Case of Emergencies
Get PDFAbstract Emergencies are bound to happen anywhere at any time and as such pre-planning is necessary. This study outlined a procedure by which students on a university campus can be evacuated safely, while optimising use of available resources. Applications of optimisation techniques in campus emergency planning studies are not common, especially in developing countries. Collaboration of students is essential for a successful campus emergency evacuation, as such this study examined factors that will predict students’ behaviour in an emergency. The study adopted a location-allocation (L-A) model based decision support system (DSS) to implement the campus evacuation plan. The DSS was implemented within a geographic information system (GIS) environment. A total of 150 students were selected randomly across six faculties at Olabisi Onabanjo University, Nigeria for the study. In the event of an emergency it is proposed that all the students will move to designated assembly areas. The output from the emergency decision support system will be used to direct students from the assembly areas to appropriate evacuation points. The DSS was specifically applied in this study to find the locations of five evacuation points that will minimise travel distances of all students from thirteen assembly areas. The results from the DSS showed the average travel distance is 328.43 metres. This study used the binary logistic regression model to predict factors that will influence students to assist in an emergency. The result of the analysis showed that their level of consciousness of emergencies is the only factor that will significantly influence them to assist in an emergency. The findings from this study showed that for a disaster resilient university it must develop an all-hazards comprehensive plan, conduct regular emergency training and exercises, and develop a partnership with the host community for joint use of emergency resources.

Evaluation of Extra Virgin Olive Oil Adulteration with Edible Oils using ATR-FTIR Spectroscopy
Get PDFExtra virgin olive oil (EVOO) is categorized as expensive oil due to high-quality nutritional value. Unfortunately, EVOO is easily adulterated with other low-quality edible oils. Therefore, this study was done to differentiate and analyze the adulteration of EVOO with other edible oils using Attenuated Total Reflectance-Fourier Transform Infrared (ATR-FTIR) spectroscopy. The study was used several edible oils included canola oil, corn oil, sunflower oil, and soybean oil as an adulterant for EVOO. The adulterant EVOO samples were prepared by mixing with dissimilar concentrations of the solely edible oils (20 %, 40 %, 60 % and 80 % (v/v)). The main functional groups of EVOO and other edible oils are O-H, C-H, C=C and C=O groups were assigned around 3500 cm-1, 2925 cm-1, 3006 cm-1 and 1745 cm-1 wavenumbers, respectively. From the comparison of EVOO and other adulterant edibles oil spectra, it showed that the EVOO has the lowest absorbance intensity at around 3006 cm-1 represented double bond which is closely related to the composition of oil sample. The adulteration of EVOO was evaluated by analysing the changes in the absorbance based on the linear regression analysis graph of the bands at 3006 and 2925 cm-1 and the limit of detection (LOD) was measured. The graph of A3008/A2925 with good relative coefficients (R2) and lower LOD is more favourable than the linear regression graph of A3006 versus percentage of edible oils added in EVOO. This study showed that ATR-FTIR spectroscopy is a convenient tool for analysing the adulteration of EVOO

Get PDFNumber of active smokers in Malaysia is increasing despite availability of stop smoking clinics and smoking cessation medications. Thus, the practice of the healthcare professionals involved in providing smoking cessation intervention using evidence-based guidelines needs to be assessed using validated assessment tool. Newly invented reliable and valid questionnaire locally is needed. This study aimed to develop and validate a newly modified questionnaire to assess the knowledge, attitude and practice of medical doctors based on national smoking cessation guidelines and factors contributing to the score. The 22 items consists of mixture of true/false choice questions and Likert scaling response based on domain of 5A’s (ask, assess, advice, assist, arrange) and 5R’s (relevant, risks, rewards, roadblocks, repetitions) of the national stop-smoking guideline. The questionnaires were distributed to 131 primary care doctors. Reliability was determined using Cronbach’s alpha for internal consistency while construct validity was assessed using factor analysis. A high degree of internal consistency was observed for this 22 items (Cronbach’s alpha = 0.87), with good knowledge subscale (0.72), attitude subscale (0.58) and practice subscale (0.92). Factor analysis showed five meaningful components which represent the smoking cessation framework. This study indicates that this questionnaire is reliable and valid tool to assess the knowledge, attitude and practice on stop smoking guidelines compared to previous questionnaire

In Silico Site-Directed Mutagenesis of some Amino Acids in the C-Terminal Domain of Glutathione s-transferase from Acidovoras sp. KKS102
Get PDFA cytosolic glutathione s-tranferase from Acidovorax sp. KKS102, a biphenyl/polychlorobiphenyl degrading organism is recently known to have a dehalogenation function on various organochlorine substrates. However, little is known about the specific amino acids involved in its structural stability and catalytic process. The in silico site-directed mutagenesis of a highly conserved region, Ala154, Asp155 and Tyr157 in the C-terminal domain of the cytosolic glutathione s-transferase from Acidovorax sp. was carried out using Deep View/Swiss-Pdb Viewer molecular graphics program for all the proteinogenic amino acids. The amino acid substitutions in this region directly affected the theoretical 3D model of the transferase protein entity through alteration of the predicted stabilization forces which may in turn affect the structural stability and perhaps the activity of the enzyme
