Bacteria Flora Of The Anterior Genitalia Of The Sahelian Doe In Maiduguri-Borno State, Nigeria
Y M Bukar-Kolo, J D Amin, L T Zaria
Nigerian Veterinary Journal , 2007,
Abstract: The genital tract of animals especially the posterior part is known to harbour non-specific bacteria that are sometimes called the “normal flora”. Although the type of bacteria present and the role they play is not well understood, under stressful conditions they may cause disease (Hirsh, 1990). A variety of bacteria have been isolated from the genitalia of the doe and these include Staphylococci, Streptococci, Actinomyces, Pseudomonas, E. coli, Mycoplasma and Brucella species (Amin, 1988; Fasanya et al.,1987; Ababneh and Degefa,2006; Safiriyu et al., 2006). These organisms have been associated with disease conditions of the genitalia of animals. Adams, 1975 reported that isolation of pathogenic Staphylococci under normal and disease conditions of the genital tract revealed that they may be natural inhabitants of these organs but under conditions of stress such as following lambing, abortions etc they may cause metritis and infertility. Isolation of potentially pathogenic organisms from the normal genitalia of live and dead ewes has been reported previously (Hopwood, 1956; Amin 1988). Most of the reported cases were made from apparently healthy animals and in the absence of experimental infection; the true role of many of the isolates in reproductive disease has remained in doubt. Thus, this study was carried out to determine the ‘normal\' aerobic bacterial flora of the genitalia of apparently healthy sahelian does during different phases of the reproductive cycle.
Application of Hosaka and DJ Kim Whatmann paper protocols for rapid isolation of cowpea DNA
M Yusuf, S Muranaka, AA Zaria
African Journal of Biotechnology , 2009,
Abstract: The traditional liquid nitrogen DNA extraction method is expensive and tedious. There is, therefore, the need for cheaper and faster methods of DNA extraction for efficient application of marker assisted selection (MAS) for breeding for striga resistance in cowpea to be able to handle large number of samples at a time. Two DNA extraction methods; Hosaka (2004) and DJ Kim Whatmann paper (unpublished) were tested on cowpea line IT06K-5-83 under different conditions. The results revealed that both methods with modifications can work with cowpea. However, Hosaka (2004) method seems to be more promising than the other method for DNA extraction in cowpea because it gives better and more consistent DNA band.

EH Mshelia, LT Zaria, AH Mohammed, N Jaji
Ethiopian Journal of Environmental Studies and Management , 2008,
Abstract: The phytochemistry and antimicrobial effect of the stem, bark and leave of Asparagus flagellaris were studied. The phytochemical screening of the stem, bark and leaves showed appreciable amount of flavonoid and moderate amount of carbohydrate, cardiac glycoside and saponin while reducing sugar, ketones and pentose were detected in traces. The ethanol extract inhibited the growth of six organisms viz Escherichia coli, Corynebacteria, Klebsiella, Neiserra gonorrhoeae, Shegiella dysentariae and Candida albicans, at various concentrations, while the aqueous extract were susceptible on five organism namely Corynebacteria, Streptococcus pyogene, Proteus specie, Neiserra gonorrhoeae, and Treponema palladium.
Bilateral Cooperation between China and Congo-Brazzaville: The Other Side of the Ledger  [PDF]
Nathana?l T. Niambi
Open Journal of Political Science (OJPS) , 2018, DOI: 10.4236/ojps.2018.83016
Abstract: The relation forged between China and Africa during these recent years has been and remains topical at this time. Researchers coming from all over the world say that it is rich, solid, well-rounded, dynamic, ambiguous, win-win, tenuous, etc. Despite all of these paradigms which characterize this South-South approximation, numbers made Beijing a powerful economic partner for Africa nowadays. A relation that has shown a diversified and variable cooperation per country and geopolitical area. In that case, Congo-Brazzaville was one of the first nations in Central Africa to create fraternal relationship with the Middle kingdom. A bilateral cooperation that evolved over time. With this in mind, 53 years later, it would be interesting to make a global assessment of the ties developed between this Asian giant and that small state, sixth oil producer in Africa. Therefore, our main aim will be to carry out a thorough research and to propose some practical ideas to make this bilateral cooperation better. In order to reach this goal, we are going to conduct a desktop study by collecting and analyzing documents and audio-visual materials through a qualitative approach. Besides, we will also report conferences, seminars, interviews and official visits of heads of states including both parts.
China in Africa: Debtbook Diplomacy?  [PDF]
Nathana?l T. Niambi
Open Journal of Political Science (OJPS) , 2019, DOI: 10.4236/ojps.2019.91012
Abstract: The public debt is surely one of the most important challenges of the 21st century for many African countries. For this continent—which has a young and dynamic population—it remains complicated to reach development and financial autonomy as long as it supports a lot of debt obligation. However, that modern African legend of Sisyphus got more interest thanks to China’s return. Indeed, during the last two decades, we have seen Beijing’s investing more in Africa on behalf of a certain old friendship and become the first bilateral commercial partner of the African continent (2009) instead of Western powers. This change created new political and economic contexts swaying between competition and cooperation according to protagonists (governments, national and international economic operators …) and situations. At that stage, the Chinese diplomacy used in Africa has been sometimes perceived as an opportunity, sometimes as a curse by observers. That is why many researchers, influenced by the rumors of a new colonialism, compare it to a “Debtbook Diplomacy”. And because journalists are always only presenting one part of the problem, it is easier to compare Chinese presence in Africa as an invasion. This article’s goal is to make a modest contribution to the long list of papers already written with the purpose to highlight Sino-African relations through a qualitative research (collection, comparison and analysis of documents, interviews, reports …).
Competing definitions of contextual environments
Zaria Tatalovich, John P Wilson, Joel E Milam, Michael Jerrett, Rob McConnell
International Journal of Health Geographics , 2006, DOI: 10.1186/1476-072x-5-55
Abstract: The estimates of contextual variables vary significantly depending on the choice of neighborhood boundaries and weights. The choice of boundaries therefore shapes the community profile and the relationships between its components (variables).Multilevel analysis concerned with the effects of contextual environments on health requires careful consideration of what constitutes a contextual unit for a given study sample, because the alternate definitions may have differential impact on the results. The three alternative methods used in this research all carry some subjectivity, which is embedded in the decision as to what constitutes the boundaries of the communities. The Minimum Bounding Rectangle was preferred because it focused attention on the most frequently used spaces and it controlled potential aggregation problems. There is a need to further examine the validity of different methods proposed here. Given that no method is likely to capture the full complexity of human-environment interactions, we would need baseline data describing people's daily activity patterns along with expert knowledge of the area to evaluate our neighborhood units.In recent years, health researchers have increasingly emphasized the importance of contextual environments for understanding individual health outcomes [1-6]. These types of studies are typically referred to as contextual analysis [7] and they usually involve one or more forms of multilevel analysis. The principles of multilevel analysis have been described in detail by numerous authors [8-11]. Essentially, multilevel analysis uses data sets on individuals nested within neighborhoods and enables simultaneous examination of the effects of individual and group level variables on individual level outcomes [11]. The logic behind incorporating group level data into analysis is that they may provide some additional information that cannot be adequately examined or measured at the individual level. This aspect makes multilevel analysis
Hand-held cow horn: Resurgence of an old arm or a potential terrorist weapon
Lawal Khalid,Adamu Ahmed; Division of General Surgery, Department of Surgery, Ahmadu Bello University Teaching Hospital, Zaria; Nigeria
Journal of Injury and Violence Research , 2012,
Abstract: A 23 year old man presented with intestinal evisceration from stab injury to the left side of the abdomen with a hand-held cow horn at a local night party. He complained of severe abdominal pain and bleeding at the site of injury. He was hemodynamically stable. At emergency exploration, the eviscerated bowel was viable with no adjacent mesenteric tear. Other intra abdominal organs were normal. The eviscerated bowel was lavaged and reduced into the abdomen through the 7cm anterior abdominal wall laceration. The laceration was repaired and abdomen closed in layers. Post operative recovery was uneventful. The hand-held cow horn can easily be concealed and may pass through security checks undetected. It should be added to the ever increasing list of weapons of small scale terror.
Working Memory and Reading Development  [PDF]
T. L. Ferreira, C. M. T. Valentin, S. M. Ciasca
Psychology (PSYCH) , 2013, DOI: 10.4236/psych.2013.410A002
Abstract:

Purpose: To evaluate the development of working memory and reading in proficient students from 1st to 4th year of elementary school. Method: Participants were 19 people of both genders, with an average age of 8.26 years, enrolled between the 1st and 4th year of elementary school, who met the proposed inclusion criteria and were proposed and evaluated for working memory and reading level. Results: There’re no significant differences in the level of reading and working memory between genders male and female. The research points to an improved performance of working memory with the increasing age and educational level. The students belonging to the 3rd and 4th year showed better results in the physical assessment of working memory, as well as in the evaluation of the reading level. Conclusion: In this study, it was observed that with the increasing age and schooling, there was an improvement in the performance of working memory, and consequently a better performance in reading. But it cannot be inferred that only the working memory and reading complement themselves bidirectionally, because the literature indicates that other factors also help the development of reading.

P. O. Okerentugba, T. L. Ataikiru, T. Ichor
American Journal of Molecular Biology (AJMB) , 2016, DOI: 10.4236/ajmb.2016.62007
Abstract: Several studies have reported on the capabilities of different yeasts to utilize hydrocarbons hence the need to ascertain the petroleum hydrocarbon biodegradation potential of yeast isolated from palm wine. The study aimed at isolation, characterization and testing of yeasts from palm wine for biodegradation of petroleum hydrocarbons. Hydrocarbon utilizing yeasts (HUY) were isolated from palm wine, a rich sugar substrate from a non-oil impacted environment using Bacto Bushnell Haas broth. The medium composed of 0.2 g MgSO4, 0.02 g CaCl2, 1 g KH2PO4, 1 g K2HPO4, 0.05 g FeCl2, 1 g/L NH4NO3, pH (7.2 ± 0.2) and mineral salt broth comprising of 4.4 g KH2PO4, 8 g (NH4)2SO4, 2 g Na2HPO4·H2O, MgSO4·7H2O, 0.1 g FeSO4, 0.01 g/L CaCl2, pH (4.5 ± 0.2) supplemented with palm wine (0.5%) and crude oil (1%). Yeasts isolated from an enriched medium and palm wine showed similarities. Yeast isolates were further screened for hydrocarbon degrading potentials using the Bacto Bushnell Haas broth containing 2, 6-dichlorophenol indophenols as the indicator agent. The isolates were identified using microscopic, macroscopic, fermentation and molecular characteristics as Candida adriatica (ZIM 2468) and Candida taoyuanica (MYA-4700).
Jealousy Induction Methods, Sex, and the Big-5 Personality Dimensions  [PDF]
Jennifer L. Weinstein, T. Joel Wade
Psychology (PSYCH) , 2011, DOI: 10.4236/psych.2011.25080
Abstract: One-hundred and twenty five participants were administered an online survey to investigate: which type of cheating, emotional or sexual, is more likely to be used in an attempt to induce jealousy in a partner, which type of cheating is perceived as most effective for inducing jealousy, and whether or not the Big-5 personality dimensions are related to the choice of jealousy induction technique. Emotional cheating was hypothesized to be selected more often, and given a higher effectiveness rating, than physical cheating for inducing jealousy in a partner. Additionally, men were hypothesized to rate physical cheating as worse than emotional cheating while women were expected to rate emotional cheating as more hurtful. The results were partially consistent with the hypotheses. Emotional cheating was selected as the method to induce jealousy most often and was rated as the most effective way to induce jealousy. However, physical cheating was rated as more upsetting by both men and women. Additionally, Big-5 personality dimensions were not related to choice of jealousy induction method or reactions to physical or emotional cheating. The findings are discussed in relation to prior research.
