In this research, the combustion of two grass species (Cymbopogon schoenanthus and Cymbopogon citratus) was analyzed under thermogravimetric analysis; which is a common way for energy source at the different heating temperature of 20ºC/minute intervals from ambient temperature to a heating temperature of 600ºC. The results show that in camel grass the active temperature for the degradation was 392.74ºC which is the active heating range for the decomposition of the grass sample. The thermo-gravimetric temperature at 339ºC shows the highest degradation activity when compared to the first and second phase of the analysis. While in lemongrass the active temperature was 323-480ºC with the highest weight loss of 35.26–36.18%. This analysis shows the thermal decompositions of the plant biomass used, it fuel potentiality and highest temperature for the decomposition of the biomass.

Colorectal Cancer Prevention in New Immigrant Women: A Pilot Study of an Educational Program to Fortify Food Literacy and Physical Activity

Tsorng-Yeh Lee, Grace Ho, Beryl F. Pilkington

Journal of Scientific Research and Reports, Page 1-8
DOI: 10.9734/JSRR/2017/39043

Purposes: (a) to educate new immigrant women (NIW) about Colorectal cancer (CRC) screening services provided by the Canadian health care system, and (b) to advance NIW’s knowledge on CRC prevention strategies, focusing on food literacy, eating habits, and physical activity.

Methods: A pretest-posttest design was used to examine the efficacy of an educational program. Four instruments were used to collect data. Fifty participants filled out the questionnaires before and after the program. Statistical analysis of Repeated Measures ANOVA was performed. 

Results: The Repeated Measures ANOVA indicated that participants' knowledge significantly improved following the food safety educational program. Repeated Measures ANOVA also showed that the educational program had an effect on participants’ perceived behavioral control subscale on feeling about cancer and cancer screening and this effect lasted two months after the program. Furthermore, participants’ physical activity during their leisure time was gradually increasing from week 1 to 2 months after the educational program.

Conclusion: An educational program on food safety resulted in improved food safety knowledge for Chinese immigrants. Participants also have a better understanding of information related to healthy eating habits and colorectal cancer prevention and screening.

DOI: 10.9734/JSRR/2017/37835

The paper determines the natural activity concentrations of 226Ra, 232Th and 40K   in water samples from various ponds and rivers in some parts of Ondo State, Nigeria. The measurement was done by gamma-ray spectrometry system with high-purity germanium detector. The activity concentrations in ponds for 226Ra, 232Th and 40K varied from (0.15±0.01 to 0.82±0.04 Bq/l), (0.52±0.10 to 1.64±0.20 Bq/l) and (0.25±0.05 to 3.60±0.21 Bq/l) respectively and the activity concentration in rivers varied from (0.17±0.01 to 0.23±0.04 Bq/l), (0.56±0.02 to 1.38±0.20 Bq/l) and (0.46±0.02 to 5.38±0.10 Bq/l) respectively. The results of the calculated annual effective doses for different age groups due to ingestion and the health implication with respect to the hazard limit set by the International Commission on Radiological Protection (ICRP) were considered.

DOI: 10.9734/JSRR/2017/38526

Aims: The study aimed to determine the status of accumulations of heavy metals (Cr, Cu, Pb and Cd) in water and soil. The study also established the main entry of heavy metals in the river since heavy metals are referred to a diverse range of highly toxic or poisonous micro-pollutants present at very low concentrations in the environment arising from industrial and mining activities are discharged into sources of water at many sites.

Study Design: The study designed to analyze heavy metal magnitude in water and soil samples on the Msimbazi River from Vingunguti to Jagwani flood area.

Place and Duration of the Study: Msimbazi River is located in the Dar Es Salaam city, Tanzania. It originates from the highland of Kisarawe in cost region. Msimbazi River receives effluent discharges from several industries of different manufacturing processes like dyes and paints, steel, batteries, food processing, vingunguti abattoir, and electrical product. The study was done between March and June 2012.

Methodology: All analysis works were done at the Environmental Laboratory of Ardhi University using the Atomic Absorption Spectrophotometer technique (AAS).

Results: The results showed that water and soil around Msimbazi River have lead, chromium and copper concentrations were higher than the permissible limit as EPA and TBS. There are variations of heavy metals along Msimbazi River due to the discharge of the toxic waste such as oil, industrial wastewater which cause high pollution along and within the river.

Conclusion: In order to prevent this water source and health of the people, Msimbazi River should not be used for vegetable irrigation as water observed to have heavy metal exceeded permissible limits as per WHO and TBS. Those industries, garages and other economic activities around Msimbazi River have to be rebuilding far away from the river and wastewater should be treated before discharging to the river.

Background: Needle Prick injury is a common occupational hazard to medical doctors, associated with transmission of blood borne infections like Human immunodeficiency virus, Hepatitis B/C and others. This research work is on the awareness and attitude towards the management of needle prick injuries among medical doctors in Port Harcourt Local Government Area of Rivers State.

Methods: Six research questions and six null hypotheses were formulated to achieve the essence of the study. A cross-sectional descriptive survey was adopted with a sample size of 324, using a purposive cluster sampling technique. A self-structured questionnaire that was validated by three Public Health lecturers at the Imo State University, Owerri was used to obtain the data. Data were collected, collated and analysed using statistical package for social science (SPSS) version 21.0.

Results: The study revealed a 100% (high) level of awareness and positive attitude towards management of needle prick injuries among the study population. It also revealed that gender and age in practice has no influence or effect on the level of awareness and attitude of medical doctors in in the study area towards the management of needle prick injuries.

Conclusion: The participants have high level of awareness and positive attitude towards the management of needle prick injury, with age in practice and gender having no influence on their level of awareness and attitude towards management of needle prick injuries. Adherence to Universal precautionary measures, continuous re-training of healthcare workers on infectious disease control, proper management of needle prick injuries and safe work place practice remains the means of preventing infectious diseases in hospitals and the health sector at large.
