John Jiya Musa, Martins Yusuf Otache, Elijah TsadoMusa, Michael Eneojo Omale, Ibrahim Ibrahim Yahuza Yerima
Open Access Library Journal (OALib Journal) , 2019, DOI: 10.4236/oalib.1105683
Abstract:
Water quality is gradually falling due to human activities, thus making clean water for both domestic and agricultural activities scarce. Population growth is expected to directly or indirectly move up from its current status by about 55%, thus increasing water stress or severe water scarcity over the next generation. This study is aimed at statistically ascertaining and determining the physico-chemical properties of some hand-dug wells in Niykangbe, an agrarian community in Nigeria. A total of twenty five samples were collected for each year during the dry season for a period of three years. Replicate samples were collected on monthly bases for a period of five months during the years 2014, 2015 and 2016. The results obtained indicated that aluminum, cyanide and manganese were not present in the water samples. The pH ranged between 7.10 and 7.70, electric conductivity ranged between 157 and 467 μs/cm and the temperature ranged between 30℃ and 33℃. The nitrate content ranged between 5.00 and 67.30 mg/l while nitrite ranged between 0.02 and 0.09 mg/l. The analysis should be that most of the parameters were still within the recommended standards of NSDWQ and WHO. It was concluded that intermittent test is carried out to ascertain the level of fitness of the various water samples for both domestic and agricultural use.
Comparative antioxidant capacity, membrane stabilization, polyphenol composition and cytotoxicity of the leaf and stem of Cissus multistriata
J Omale, PN Okafor
African Journal of Biotechnology , 2008,
Abstract: In this present study, a comparative evaluation of the antioxidant capacities, phenol and polyphenol composition, membrane stabilization, and cytotoxicity to brine shrimps (Arthemia salina) of the leaf and stem extracts of Cissus multistriata were carried out. 2,2- Diphenyl-1-picryl hydrazyl (DPPH) radical scavenging effect of the extracts was determined spectrophotometrically. The highest radical scavenging effect was observed in the stem extract with IC50 of 29.25 ìg/ml. The potency of radical scavenging effect of the stem extract was close to the synthetic antioxidant quercetin with IC50 of 21.05 ìg/ml. The antioxidant activities of each extract increased with increasing concentration of extracts. The phenol and polyphenol content of the stem varied between 0.564 ± 0.000 to 6.200 ± 0.557% and that of the leaf content is lower (0.523 ± 0.000 to 3.400 ± 0.355%). The higher amount of phenolic compound in the stem could be contributory to the greater radical scavenging effects observed. The methanolic extracts exhibited minimum and maximum percentage membrane stability of 51.364 ± 11.241 and 56.098 ± 14.654% on human erythrocyte. The highest membrane stabilizing activity was observed in the stem extract with percentage stability of 56.098 ± 14.654%. The activity of the extracts was comparable to the standard anti-inflammatory drug (Indomethacin) used. The extracts are less toxic to the cell (Arthenia salina) with their LC/EC50 higher than that of standard potassium dichromate used. The results obtained in this present study indicate that C. multistriata can be a potential source of natural antioxidant and is relatively safe.
Restorative Justice and Alternative Dispute Resolution: An Analytical Discourse for African Professionals
Omale, Don John O.
International Journal of Advanced Legal Studies and Governance , 2011,
Abstract: The strong advocacy for Restorative Justice and Alternative Dispute Resolution in Africa; and evolving models is a welcomed development for penal reforms and conflict resolution. However, as an African adage says "it is when a tripod is being designed and constructed that the legs should be set straight to forestall cook wares falling". This study drew its strength from a completed Doctor of Philosophy (PhD) dissertation initially reviewed with the aim of setting the record straight in the meaning and conceptions of restorative justice and alternative dispute resolution for African practitioners. This is imperative because as the saying goes "words put differently make different meanings, and meaning put differently yield different actions". So if restorative justice and alternative dispute resolution must advance professionally, and as academic disciplines in Africa, practitioners and academics must understand the 'thin' differences inherent in the principles and practice of restorative justice, and alternative dispute resolution.
Riots/Jail Breaks in Nigeria Prisons: An Aetiological Study
Don John O. Omale
Canadian Social Science , 2013, DOI: 10.3968/3284
Abstract: In recent times, riots/jail breaks in the Nigerian Prisons have become recurrent phenomena. So rampant, that they pose security concerns and serious threats not only to the prison authority, but also to both the government and the people of Nigeria. For instance, on the 2nd of January, 2013 about 20 inmates escaped from a secured prison in Sagamu, and on 15th February 2012 Boko Haram attacked Koto-Karfi prison in Kogi State, releasing about 119 Awaiting Trials Persons (including Boko Haram suspects). Other examples of riots/jailbreaks in the Nigerian Prisons include: The February 2004 riot in Ikoyi prison, the Port Harcourt prison attack of 2005 and Onitsha prison attack of the same year. On 6th September 2007 riots occurred in Kano prison and on 8th September 2007 riots occurred at Agodi prison in Ibadan. On Wednesday 3rd June, 2009 about 150 inmates broke jail at Enugu prison. On 20th of April, 2010 Kaduna prison experience jail break; and the Boko Haram attacked Bauchi and Maiduguri prisons in 2010 and 2011 respectively, to mention a few. This study investigates this phenomenon using an 18 items semi structured questionnaire administered to 240 inmates of Kaduna Central Prison, and a Focused Group Discussion (FGD) with 10 Deputy Controller of Prisons (DCP) to unravel the aetiology of prison riots/ jailbreaks in Nigeria. Key words: Prison and security; Jailbreaks; Nigerian prisons

Abstract: this study was carried out on the bioremediation of used motor oil contaminated soil artificially contaminated to a pollutant level of 40,000ppm using biostimulation and bioaugmentation remediation techniques for 42 days. four treatment options were investigated in wooden microcosms: control (t1), water amended (t2), biostimulation (t3) and hybrid of biostimulation and bioaugmentation (t4). the effectiveness of bioremediation processes were monitored using the total petroleum hydrocarbon removal (tph) and total bacterial count (tbc). t3 had the highest tph removal rate (69.2±0.05%), followed by t4 (65.2±0.25%) and t2 (58.4±0.5%); the control (t1) had the lowest tph removal rate (43.2±1.5%). tbc revealed that bioremediation actually took place; t4 had the highest maximum bacterial growth of 9.6e+07cfu/g, followed by t3 (7.2e+07cfu/g), t2 (1.7e+05cfu/g) and t1 (1.65e+05cfu/g). in addition, t3 had the highest metal removal rate (2.172%) and t4 had the lowest metal removal rate (0.203%).
PHYTOCHEMICAL COMPOSITION, BIOACTIVITY AND WOUND HEALING POTENTIAL OF EUPHORBIA HETEROPHYLLA (Euphorbiaceae) LEAF EXTRACT
Omale James,,Emmanuel .T. Friday
International Journal of Pharmaceutical and Biological Research , 2010,
Abstract: Villagers have traditionally used E.heterophylla parts to treat a variety of ailments. The objective of this study was to evaluate the phytoconstituents, bioactivity and wound healing potential of E.heterophylla leaf extracts in experimental Rattus novergicus.All experiments were conducted following standard procedures. The order ofdecreasing concentrations of the Phytochemical is alkaloids>cyanide >tannins>flavonoids> saponins. The order of decreasing cytotoxicity is aqueous extract (fresh)> ethanol extract (fresh)> ethanol extract (dry)> aqueous extract (dry). The extracts in the form of an ointment was used for evaluating the wound-healing potential in an excisionwound model. The wound-healing property observed in E.heterophylla is attributed to the phytoconstituents and the faster process of wound-healing could be a function of either the individual or additive effects of the phytoconstituents.The ethanol extracts exhibited high percentage of wound closure. The prophylactic effect elicited by the extracts in terms of wound contraction and related biochemical arameter strongly support the healing and sealing characteristics of E.heterophylla leaf gel in rats following topical administration.
EXCISION AND INCISION WOUND HEALING POTENTIAL OF SABA FLORIDA (Benth) LEAF EXTRACT IN RATTUS NOVERGICUS
OMALE JAMES,,ISAAC AYIDE VICTORIA
International Journal of Pharmaceutical and Biological Research , 2010,
Abstract: Saba florida (Benth) belongs to the family Apocynaceae. It is very abundant in undisturbed forest and coastal regions in Africa. It is a folkloric medicine for a variety of ailments including skin ulcer. However there are no scientific reports on wound healing activity of the plant Saba florida (Benth).This study was carried out to evaluatethe wound healing potential of Saba florida leaf extract in Rattus novergicus as experimental animals. All experiments were conducted following standard procedures. The extract in the form of an ointment was used for evaluating the wound healing potential in excision wound model. In the incision wound model , the extract was administered orally in graded doses of 100, 200 and 400 mg/kg b.w. Saba florida leaf extract demonstrated higher percentage of wound contraction in the excision wound model compared to the standard (Povidone iodine ointment) and the control. In the incision wound model healing rate was dose dependent. In both excision and incision wound models, wound surface protein increased and wound surface microbial load decreased after days. The healing or wound contraction elicited by Saba florida leaf extract in this investigation following topical and oral administration strongly support the verbal claim of traditional octors on the use of this plant.
Perturbed Planar Restricted Four-Body Problem with Repulsive Manev Potential  [PDF]
Jagadish Singh, Solomon Okpanachi Omale
Open Access Library Journal (OALib Journal) , 2019, DOI: 10.4236/oalib.1104980
Abstract:
In this paper, we carried out a numerical study of the planar restricted four-body problem with repulsive Manev potential and perturbations in the Coriolis and centrifugal forces such that the peripherals possess Eulerian configuration. We have presented the equations of motion in the rotating frame and investigated the existence and location of the equilibrium points. We have found that there exist six equilibrium points all of which lie along the coordinate axes and shift in positions as the perturbation parameter is varied. We have also examined the linear stability of these equilibrium points and they are found unstable. The dynamical behavior of this system is also investigated using the Lyapunov Characteristic Exponents and the system is found to be chaotic.

J Tukur, AO Omale, H Abdullahi, Z Datti
Annals of African Medicine , 2007,
Abstract: The use of fundal pressure to assist a woman in labor is a controversial procedure. Its benefits are yet to be scientifically confirmed and it is associated with complications such as perineal lacerations, uterine rupture and uterine inversion. A case is reported of a 28year old Gravida 5 Para 4 + 0 (3 Alive) who presented to Aminu Kano Teaching Hospital, (AKTH) Kano, Nigeria with uterine prolapse following fundal pressure done in the first stage of labor in a peripheral hospital. She was delivered by Cesarean section and the prolapse successfully reduced under general anesthesia. Health workers need education on the risks associated with fundal pressure. Alternative methods of aiding women in labor should be promoted.

Annals of African Medicine , 2007,
Abstract: Background / Objective : Endocrinologic disorders and infertility are common all over the world; the prevalence of infertility is high in sub-Saharan Africa. Several authors have suggested that the increased incidence of infertility in Africa is due to high prevalence of sexually transmitted diseases. To evaluate the contributions of endocrine abnormalities to infertility in the male in Kano, Northern Nigeria. Methods : A total of five hundred males, aged between 28 and 56 years were evaluated over a period of 4 years (2001 - 2004).The hormones were analyzed using electrochemiluminescene immunoassay technique. Results: Hormonal abnormalities were detected in 22% oligospermic, 40.7% severe oligospermic, and 42.7% azoospermic subjects. Conclusion : Endocrine abnormalities are common in the infertile males. The reason for the observed endocrinopathies is not known, appropriate laboratory investigations are essential for effective patients management. Further study to ascertain the cause(s) of hormonal derangements is suggested.
