The prevalence and determent of HIV/AIDS Risky practices among students Afar Regional State, Northeast, Ethiopia 2019

Frewein Yilma
Human immunodeficiency virus deficiency virus remains as a serious public health importance. Practices that expose them to risk of contracting sexual transmitted diseases included HIV/AIDS is that the major effective driver. The aim of the study was to assess risky practices and associated factors for HIV/AIDS infection among students Afar Regional State Northeast, Ethiopia. An institutional-based cross-sectional study was conducted from Decembers 10, 2019 to January 12, 2020, among regular students who resided in university and college students. A pretested structured questionnaire was used per collect of the data. Using the systematic random sampling technique, a total of 800 respondents participated in the study. The data were entered into EPI info version 3.5.3 and moved to SPSS version 20 for analysis. Descriptive statistics bi-variate and multi variable analyses were done. A p-value < 0.05 was considered the statistical significance of the association between factors (independent variables) and risky sexual activity. The Odds’ ratio was also used to determine the presence and the degree of association between dependent and independent variables. Among 800 respondents, the magnitude of risky sexual behaviors was found to be 33.1%... The most predictor variables for risky sexual behavior among the students were marital status (AOR = 3.18, 95% CI = 1.96–5.17), year of study (AOR = 3.57, 95% CI = 2.13–5.96), ever visted to nightclubs (AOR = 7.11, 95% CI = 4.88–10.37) and ever chewing Khat (AOR = 2.78, 95% CI = 1.56–4.96) were statistically associated with risky sexual practice. The prevalence of risky HIV/AIDS practice was high, and 33.1% of study participants were engaged in risky practice. Efforts to increase Awareness creation activity on the importance of safer sex behaviors and consequences of substance use like chewing khat through health education and counseling are highly recommended.

A Study of Social genetics and Linguistic Inquiry

Samuel Leykun
Human being on Earth has undergone several transitions during its history, from the fire age to modern technology. There has been notable progress in linguistic development and social development. Sociolinguistics and Social genetics as a newly emerging discipline have strong relationship and engaged with one another. This study focus on the critically analysis of social genetics and linguistic inquiry of human being regardless of anything. The objectives of the study were to introduce this complex idea to the biologists and linguists to reduce their racial biases and to make sense of social genetics and sociolinguistics are the major parameter of human race and genetics than hereditary genetics. The critical paradigm is used as paradigm of the study. Regarding techniques of data analysis, the qualitative approach is utilized in this study. Concerning data collection tools, the secondary data were collected from journals, findings of different researches, books, and proceedings. Therefore, this research is a desktop research. To mention some of the findings, the concept of hereditary genetics distinguish an individual or a group of individual from the other is a reputational way that triggers a misconception, and incorrect. The world outlook, and paradigm of the target speech community or an individual is not a consequence of hereditary genetics, rather this can be considered as a misconception of genetics. 99.9% of the DNA of two human is identical. But also, more than 99% of language of the world share same consonants and vowels. The phoneme chart of language of the world is almost the same. Therefore, ethnic conflict in different part of the world particularly Africa, Arab countries, and Asia has no theoretical and practical background. More explicitly, ethnic conflict among two races has no reason and a conflict between groups are those share 99.9% of the DNA and 99% of the linguistic characteristics. Read More

A seroprevalence study of Contagious Bovine Pleuropneumonia (CBPP) and Assessment of Risk Factors on Indigenous Afar Cattle in Selected Districts of Afar Region, Afar, Ethiopia

Wossene Negash
Contagious Bovine Pleuropneumonia CBPP) is a transboundary and economically devastating cattle disease rampant in lowland areas where majority of the country’s cattle population are reared by the pastoral production system. Influenced by pastoral production system, CBPP has continued to be a productivity impedance to pastoral area settings. Studies suggested that CBPP is being prevalent in lowlands than mid and highland agro-ecologies. No matter how CBPP is a prime constraint to cattle producers in Afar region, research outputs on CBPP are unavailable compared to highland areas in the country. Thus, the objectives of the current study were to determine serological prevalence of CBPP and evaluate associated risk factors in selected districts of the region. A cross-sectional study design was conducted on local Afar cattle aged six months and above from February 2018 to January 2019 in selected Dubti, Asaita and Chifra districts, Afar region. From each randomly selected animal, 8ml blood was drawn from the jugular vein into plain vacutainer tubes. Determined by Thrusfield formula, a total of 420 serum samples were collected. Samples were labeled, packed and transported to Samara University for separation of serum and blood and sera stored at -20C. Using c-ELISA, antibodies against Mycoplasma mycoides subspecies mycoides small colony (MmmSc) were detected at National Veterinary Institute (NVI), Ethiopia. Data were analyzed using Stata 14.0 software. Using descriptive statistics, prevalence and frequencies were computed. Of 420 samples tested by c-ELISA, 158 samples were found to be positive for CBPP providing an overall prevalence of 37.6% with 95% CI (32.97-42.27). Of the three risk factors (age, sex and district) assessed by Chi-square (χ2), only two (age and district) were found to be associated with CBPP (P<0.05). Both age and district were significantly associated with the disease by bivariate logistic regression. However, only district was found to be significantly associated with CBPP by multivariate logistic regression analysis using 95 % CI and P-value less than 5%. The study addressed the current status of CBPP in the study areas to be higher, urging prompt and coordinated intervention to be set in place. Read More

Activated charcoal prepared from Adansonia Digitata(baobab) pericarp has been used for the removal of methyl red dye from simulated aqueous solutions employing adsorption method. The effect of adsorption was studied by using different parameters such as pH(2-4), contact time(50-200min), initial dye concentration(50-200mg/L) and adsorbent dosage(1-4g). The extent of adsorption was determined by employing uv-vis spectrometer. The experimental data was verified by Freundlich model and found to be satisfactory. Under the experimental conditions the parameters at the maximum adsorption ability have been determined for the dye and reported. Read More
