Abstract:

Purpose: With increasing incidents of injustices in Nigeria, concerns for social justice have been topical. Social workers are expected to be at the fore of campaigns and implementation of social justice, hence, the question of their preparedness to match these expectations. This article sets out to ascertain whether the content of the curriculum of the Department of Social Work, University of Nigeria, Nsukka, meets these expectations. Method: Focus group discussion and in-depth interviews were used to collect data from purposively selected 20 undergraduates and four postgraduates. Results: Findings show that the students believe that the curriculum has enough social justice content though there is a need for review and change in delivery methods. Discussion: The incorporation of social justice into the curriculum encourages its application by practitioners. It is important to introduce more courses on social justice to impact more on the students and train teachers on better delivery methods.

Abstract:

Astronomy research and teaching has been actively carried out in the Department of Physics and Astronomy at the University of Nigeria, Nsukka for the past 20 years and before that, in the Department of Mathematics. Economic problems, lack of recent journals, text books and computing facilities, and very poor communications have made it increasingly difficult for these programmes to continue. Added to these problems there is often unrest in the Universities resulting in frequent closures and almost constant uncertainty about payment of the already poor salaries. It is a wonder that anyone could be even thinking of astronomy.

Abstract:

This paper reassessed the influence of Igbo segmentals on the teaching and learning of English sounds in the University of Nigeria Nsukka. It aimed to determine the extent to which phonological interference in Igbo language has negatively influenced the teaching and learning of the English phonemes. The study was anchored on Lado’s (1957) theory of Contrastive Analysis Hypothesis (CAH). The data for study were elicited from a ten-item questionnaire which was randomly distributed to 50 First Year students of the Department of English, University of Nigeria, Nsukka. Again, the findings of previous researches were utilized to contrastively augment the primary data. Using both simple percentage system and Lado’s framework, the data were analyzed quantitatively and qualitatively. The results showed that the recommendations of previous researches were yet to be fully implemented because there are still cases of language transfer at the level of phonology, particularly, the segmental level. Thus a good number of suggestions and recommendations were made to alleviate the problem.

Abstract:

In this study, we assessed the management control system used for effective job performance among librarians in five federal university libraries and five State university libraries in South East, Nigeria. Our 38-item questionnaire was validated by three experts: one from the Department of Science Education (Education Measurement and Evaluation unit) and two from the Department of Library and Information Science at the University of Nigeria, Nsukka. Later we used descriptive statistics and found out that the university libraries adopted performance appraisal system, duties rotation system, controlled activities system and regulation of staff attendance to a great extent, and also that the management control system has contributed to the effective job performance since it enables employees to understand their job expectations and to encourage librarians’ positive work attitude. Based on these findings, we recommended that performance appraisal and staff evaluation should be performed from time to time to identify areas which require improvements. Henceforth, federal and state governments in Nigeria should make funds available for university libraries to enable them adopt effective management control system and procure facilities and resources to enhance job performance in their libraries among others

Abstract:

The site of Ugwuele-Uturu was discovered in 1977 and excavated on two occasions between then and 1981. A number of general accounts were produced by the excavators, but to a large extent the site remains unpublished. No detailed account of the excavations or of the excavated material is widely available. In the meantime, controversy as to what the site represents continues, in the light of F.N. Anozie’s claim that it is Acheulean. This paper provides a record of the author’s visits to the site in 1978 and 1981, when he was a staff member of the University of Ibadan, and also presents some results from his study of the artefacts kept at the Department of Archaeology at the University of Nigeria Nsukka in 1980. In his view, on the basis of the available evidence, the site represents an axe factory of likely Holocene date. It is hoped that this record, apart from its historical documentary value, will stimulate new work on the site and the material from it, so that its nature can be established beyond doubt.

Abstract:

The study examined security awareness as a panacea for effective management of safe school Initiative and students’ academic achievement in unity schools in Nigeria. Three research questions guided the study. The study adopted descriptive survey design. The population of the study comprises 104 principals of unity schools in Nigeria. There was no sampling technique adopted since the entire population was manageable. The instrument for data collection was structured questions developed by the researchers titled: “Safe School Initiative Questionnaire (SSIQ)”. The instrument was validated by three experts, two from the Department of Educational Foundations and one in the Department of Science Education (Measurement and Evaluation Unit), all from the University of Nigeria, Nsukka. The reliability yielded a co-efficient of 0.83 using Cronbach Alpha techniques. Mean and standard deviation were used to answer the research questions. The findings of the study revealed that the rationale for launching safe school initiative was to protect Nigeria students in school from being attacks, to reduce the dropout rate, to enable the students to be conscious of security situation in schools, prevent future attacks on schools, and general protection of education sector in Nigeria. The findings of the study also revealed that school based management strategies can be adopted for safe school initiative implementation in unity schools in Nigeria. Based on the findings of the study, the following recommendation were made, among other that, federal government should provide safety facilities especially perimeter fencing in unity school in Nigeria.

Abstract:

The study investigated the effect of bibliotherapy on the truant behaviour of schooling adolescents in North West Nigeria. Two research questions were posed to guide the study. The study adopted a Quasi-experimental design. The population for the study comprised of 824 identified SSII schooling adolescents with truancy behavioural problems drawn from the four selected schools in the North West Nigeria. The sample size used for the study was 296 SS II schooling adolescents with truant behaviour. The study adopted a structured questionnaire which was developed by the researchers for data collection. The instrument was validated by three experts drawn from Department of Educational Foundations (Special Education Unit), University of Nigeria, Nsukka; Department of Educational Psychology and Counselling, Aminu Kano College of Islamic and Legal Studies, Kano State and Department of Psychology, Ebonyi State University, Abakaliki, Nigeria. The reliability of the instruments was subjected to Cronbach Alpha Statistics and reliability coefficient of 0.91 was obtained. Mean score and standard deviation were used to analyze the data. The findings of the study revealed that school location is not a significant factor in the mean truancy behaviour of schooling adolescents; though urban schooling adolescents had a reduced mean truancy behaviour compared to their rural counterpart. The findings of the study with respect to the interaction effect of treatments and gender on schooling adolescents’ truancy behaviours revealed no significant interaction effect of treatments and gender. Based on the findings of the study, it was recommended among others that special educators, guidance counsellors, educational psychologists, and curriculum planners should plan a programme of intervention based on the bibliotherapy techniques for schooling adolescents.

Abstract:

This study focuses on repositioning guidance and counseling and curriculum innovation in higher education in Nigeria. Descriptive survey research design was employed in the study. The study covered four Federal universities in the South-West Geopolitical zone of Nigeria, namely University of Ibadan in Oyo State; Obafemi Awolowo University, Ile-Ife in Oshun State; University of Lagos in Lagos State; and University of Ilorin in Kwara State. The population of the study comprised 241 made up of 195 student counselors and 46 professional counselors from the four selected federal universities in the South-West Geopolitical zone of Nigeria. The sampling for the study was drawn through simple random sampling technique. Structured questionnaire was developed by the researcher using strongly agreed, agreed, disagreed, and strongly disagreed options. The questionnaire was face-validated using five experts - two in the department of Measurement and Evaluation in University of Nigeria Nsukka, one in Curriculum in Ebonyi State University, Abakaliki, one in Guidance and Counseling, Nnamdi Azikiwe University, Awka; and one in Guidance and Counseling in University of Calabar, Cross River State. The data collected were analyzed using mean and standard deviation for answering the research questions. A mean of 2.5 and above was accepted while any mean less than 2.5 was rejected. The findings of the study reveal, among other things that education, sense of industry, problem solving, conducive/enabling environment, and planning are various ways professional counselors help in repositioning curriculum innovation in higher education in Nigeria. It is also recommended among other things that both expert teachers/professional counselors and student counselors should participate in the repositioning of guidance and counseling and the design and development of innovative curriculum.

Abstract:

A study was carried out at the Teaching and Research Farm of the Department of Crop Science, University of Nigeria, Nsukka to evaluate the growth and yield of four improved cassava varieties, determine their optimum NPK fertilizer rate and the best modes of fertilizer application for increased productivity. The experiment was factorial laid out in a randomized complete block design with three replications. Four varieties of cassava, four fertilizer rates and three modes of fertilizer application were used for the study. The early planting had higher survival count, number of leaves, tuber and garri yield when compared with late planting. The variety TMS 98 05 05 gave significantly (p< 0.05) higher number of leaves, tuber and garri yields of 39.8 and 9.68 t/ha, respectively, at 12 months. At 6 months of crop growth, 200 kg/ha fertilizer application rate gave significantly higher tuber and garri yield of 24.69 t/ha and 5.15 t/ha, respectively. Furthermore, 400 kg/ha of NPK fertilizer rate gave higher tuber and garri yields of 39.4 and 10.12 t/ha, respectively at 12 months of crop growth. Split application of fertilizer gave significantly higher tuber and garri yield from single application, though it is statistically similar to split-split application. Therefore, early planting, 400 kg/ha fertilizer rate and split application should be adopted for cassava production. The variety TMS 98 05 05 with higher growth and yield should also be adopted by farmers for cassava production in Nsukka derived savannah agro-ecology.

Abstract:

This paper explores the possibilities of using mobile technology in the teaching and learning of the English language. A sample of 50 Sandwich students/teachers of the English language was drawn through a multi-stage sampling technique. The instrument used to collect data for this study is a ten-item questionnaire on integrating mobile phones in the teaching and learning of English. This instrument was validated by two language experts in the Department of English and Literary Studies, University of Nigeria, Nsukka. Data collected for this study were analysed using the percentage system represented in line charts. The results showed that mobile phones are instrumental in teaching and learning of English in classrooms. The paper concludes that M-learning promotes cooperative and collaborative learning through the enhancement of learner’s use of authentic English language that would make it possible for them to construct their own knowledge. Based on the results of this research, the researchers recommend that mobile phone can be integrated in teaching and learning of English as a Second Language.

Abstract:

Lectins are carbohydrate-binding proteins that are highly specific for sugar moieties of other molecules. They perform recognition on the cellular and molecular level and play numerous roles in biological recognition phenomena involving cells, carbohydrates, and proteins. Blood groups are inherited characters which give rise to antigen-antibody reaction. A total of 120 samples of local (Nigeria) Achatina achatina snail specie were collected, authenticated at the Zoology Department of the University of Nigeria, Nsukka and 80mls of pooled crude lectin extract was obtained. Purifications were performed on 20mls of the crude extract in three steps viz, Ammonium sulphate precipitation and Dialysis (Partial purifications), Con A Sepharose 4B affinity chromatography column (Complete purification). The affinity purified lectin was used for all the actual tests conducted in this research. The crude, partially and complete/affinity purified lectin extracts were subjected to Haemagglutination tests, Protein Assay and Specific Sugar determinations. The molecular weight was assessed by Sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) method. The results of the research showed as follows: On complete/affinity purification, 15mls of pure sample containing only the high molecular weight lectin was obtained. The respective haemagglutination tests on the crude, partially and affinity purified lectin showed on standardisation, preferential agglutination with Blood group A type. The Protein contents of the lectin was deduced to be as follows: The crude extract contains 13.5mg/dl, Dialysed precipitate – 5.7mg/dl, Dialysed supernatant – 5.0mg/dl and the Affinity purified Lectin – 0.422mg/dl. Galactose N-acetyl amine (Gal NAc) residue was determined to be its specific sugar. The SDS-PAGE analysis showed the molecular weight of the lectin to be 250 KDaltons. This research has therefore succeeded in the Purification, Characterisation and illustration of the lectinic properties of the local Nigeria snail - Achatina achatina.

Abstract:

This research developed an Intranet-Based Wiki with Instant Messaging Protocol (IBWIMP) for the Staff of the Department of Computer Science, University of Nigeria, Nsukka to enable them to collaborate on tasks; like writing of documents like, memo, project guidelines, proposal/grants, and circulars with online security consideration. The essence of this work is to improve on the contributions staff make during work, in carrying out tasks with their colleagues irrespective of the person’s location at that point in time. The existing system on ground would always require the presence of the staff within the department before they can carry out the tasks meant for them or respond to the available mails within their mail boxes located within the general office of the department. In regard to such situation, there is always delay in the processing of such mails or documents that could require urgent attention of the supposed staff therefore could cause serious damages. This research established a better internet connection for the security of the system and the documents therein by the use of virtual private server (VPS) hosting on virtual private network (VPN). This system allows the collaboration between the staff of the department and external persons, or partners classified as external staff user on documents like circulars that normally come from outside the department. This system automatically sends emails to the supposed users whenever the admin posts a document via the Short Message Transfer Protocol (SMTP). The system is accessed online by the users from any location once there is accessible internet connection and users can collaborate on the development of any posted document at the same time. This application was designed using Object Oriented Analysis and Design Methodology (OOADM) and implemented using Hypertext Markup Language (HTML), JavaScript, Cascading Style Sheet (CSS), CkEditor, Hypertext Pre-Processor (PHP) and MySQL database management system.

Abstract:

This study analysed journalists’ views on newspaper funding and survival in Nigeria. The study adopted survey research design to obtain data in this study. The population of the study was 1478 comprising 516 active NUJ members in the FCT and 962 members from Lagos. The sample size of 169 was determined using Taro Yamene’s (1967) sample size determination published table (cited in Kusugh, 2017). To sample respondents in this study, multi stage sampling procedure was used. Structured and Semi Structured interviews were used as instruments for data collection by the researcher in the two cities. The research instruments were face and content validated by the three experts, one from the Department of Mass Communication and two statisticians in the Faculty of Statistics, University of Nigeria, Nsukka, to ensure that it measured the appropriate data. The reliability of the instrument was ensured and the result showed a Cronbach’s alpha value of 0.786, suggesting that the items have relatively high internal consistency. Data were collected with the help of NUJ leadership in Abuja and Lagos State Councils as well as Research Assistants at the Benue Liaison Offices in the two cities. The data collected were analysed using descriptive statistics and the Pearson Product-Movement Correlation Coefficient was employed to test the null hypothesis in this study. The findings from the research are thus: journalists believe that funding is important to determine newspaper survival. They also feel that traditional funding sources should be encouraged to fill the funding gaps. Another finding is that some unconventional sources of funding such as “Total newspapering,” commercialisation of news, etc harm newspapers in Nigeria. Based on the findings, the following recommendations were made: that Nigerian newspapers should be more creative in their multidimensional approach to funding through traditional and non-traditional ways; that newspaper owners should strengthen and reposition NPAN in attaining collective goals (tax relief, subsidy on printing materials, etc); that Nigerian banks should give newspaper organisations cheaper, long term loans to enable them serve the public well.

Abstract:

The impacts of climate change risks, risk management mechanisms, and the physical environment under which farm households operate play significant roles in poverty and hidden hunger dynamics in developing countries. Extreme weather events are most often triggers of changes in risk management, which also affect the capacity of households to absorb the resultant shocks. This paper based on primary data collected as part of a PhD dissertation in the Department of Agricultural Economics, University of Nigeria, Nsukka, presents an analysis of farm households’ levels of vulnerability to extreme weather events in South-eastern Nigeria. A multistage sampling procedure was used in the selection of 120male-and 120 female-headed farm households that constituted the sample for the study. Both structured interview schedule and focus group discussion guide were used to gather data from the respondents, which were analyzed using UNDP vulnerability index. Using household adaptive capacity approach, data were collected on human, economic and institutional capacity of farmers in coping with extreme weather events. Female-headed households were more vulnerable than their male-headed counterparts to the effect of extreme weather events with respect to some of the indicators such as farming income, years of formal education, farm size, land ownership status, number of extension contacts, access to weather information, access to remittance, membership of cooperative and assistance from National Emergency Management Agency in the area. Overall, using household adaptive capacity approach, the results of the gender-based vulnerability analysis showed male-headed farming households with a vulnerability index of 0.38 while the female-headed farming households, on the other hand, had vulnerability index of 0.68. Although female-headed farm households were more vulnerable than their male counterparts, the farmers were all generally highly vulnerable to the incidence of natural disasters because of low adaptive capacity. The study recommends that government and development partners with the responsibility of protecting the environment should be gender-sensitive and redirect more effort in mitigating the negative agricultural effects caused by extreme weather events, especially among female-headed farm households who are more vulnerable.

Abstract:

Purpose: The purpose of this study was to assess the utilization of building information modelling (BIM) software for project planning in construction industries in Ondo-State. Approach/Methodology/Design: Three research questions guided the study. A survey research design was adopted for the study. The population for the study comprised of 31 construction industries with 126 Contractors and Building consultants in construction industries in Ondo-State, Nigeria. A structured questionnaire consisting of 41 items developed by the ERASMUS + programme was used for data collection. Two experts from the Department of Industrial Technical Education (Building/Woodwork), University of Nigeria, Nsukka, and one expert from Bablor Construction Company, Akure South, Ondo-State validated the instrument. The reliability co-efficient of the instrument was 0.86. Data collected were analyzed using mean to answer the research questions, while t-test was used to answer the hypotheses. Findings: It was found that the extent to which building information modelling (BIM) software are utilized are still very low. The study therefore, recommend that education and training programmes on BIM software uses should be organized for construction industries, BIM should be made compulsory for all personnel involved in construction process and a standard contract document should be made available by the government/professional bodies for all building constructors to ensure the usability of BIM for construction project to enhance the construction design, process, analyze and resolve potential hazards and ensure that the building project is completed timely. Practical Implications: The study revealed the benefit of BIM software application for project planning Hence, the importance of BIM software cannot be overemphasized in achieving high building quality, innovative virtual design and project management in the modern world. Originality/value: This paper shows that Building information modelling software is an innovative way to practically design and manage project plan. BIM adoption is needed to enhance building performance and operation.

Abstract:

There are five (5) types of mature White blood cells (WBC) or Leucocytes found in the peripheral blood viz, Neutrophils (NEU), Eosinophils (EOS) and Basophils (BAS) (granulocytes); Monocytes (MON) and Lymphocytes (LYM) (agranulocytes). Urea is an organic chemical compound, and is essentially the waste produced by the body after metabolizing protein. Urea levels can be used to detect diseases and disorders that affect the kidneys. A common disease related to irregular management of glucose is diabetes. Lectins are proteins that recognize specifically and bind reversibly the carbohydrate-containing molecules of foreign cells and that elicit diverse physiological responses in various organisms. A total of 120 samples of Nigeria Achatina achatina snail specie were collected, authenticated at the Zoology Department of University of Nigeria, Nsukka and 80mls of pooled crude Lectin extract was obtained. Purifications were performed on 20mls of the crude extract in three steps viz, Ammonium sulphate precipitation and Dialysis (Partial purifications), Con A Sepharose 4B affinity Chromatography column (Complete purification). The affinity purified Lectin was used for all the tests conducted in this research. The crude, partially and complete/affinity purified Lectin extracts were subjected to Haemagglutination tests. The Lectin was further assessed to determine its effects on Leucocytes, Urea and Glucose as follows: A total of Thirty-five (35) male Albino Wistar Rats weighing 101-180g and aged 2-3 months obtained from the Animal house of University of Nigeria, Nsukka, were used in this research. The animals were Grouped into 5 (A-E) and allowed for 2 weeks acclimatization. Graded doses of 0.04ml, 0.05ml and 0.06ml of the Affinity purified Lectin were injected intra-peritoneally into each of the Rats in Groups A-D (test groups) according to their body weights at intervals of 2 days for 1 week. Group E served as the control. Two (2) mls of blood was collected from each of the Rats before and 24 hours after the last day of Lectin Doses injections for the following tests: WBC-Total and Differential counts (using Sysmex Corporation, 1999 automated equipment), Urea and Glucose estimations (performed by means of Urease-Berthelot and GOD-PAP Randox Monza automated analyser methods respectively). The results of the research showed as follows: On complete/affinity purification, 15mls of pure sample containing only the high molecular weight Lectin was obtained. The haemagglutination tests conducted showed on standardization preferential agglutination with Blood group A type. Bar Charts statistics show that there was Post Lectin Doses injections mean increase in Total WBC, NEU, LYM and decrease in MON, EOS, BAS, Urea and Glucose levels. However, the differences in Pre and Post Lectin Doses injections mean values of these parameters were further subjected to One way analysis of variance (ANOVA) test statistics to determine if statistically significant. The ANOVA statistics show that the effects of the Lectin on all the assessed Leucocytes parameters viz, Total WBC, and Differential LYM, NEU, MON, EOS, BAS, the Urea and Glucose levels were found to be statistically insignificant. However, the EOS values of only group A was statistically significant. This research has therefore succeeded in Assessment of Activities of the A. achatina snail Lectin on Leucocytes, Glucose and Urea levels.

Abstract:

Achatina achatina snail specie are considered by many people in Nigeria, Ghana and other parts of West Africa to be the most prized snail for eating. In general, lectins bind to sugar moieties in cell walls or membrane, thereby change the physiology of the membrane to cause agglutination, mitosis or other biochemical changes in the cell. It has been deduced that lectins could be toxic and can as well be used as potent administrations that could be used or serve as substitutes for routine treatment or management of many disorders. Based on these, the toxicity of the Achatina achatina snail lectin in animals was investigated with a view to determining the nutritional value of the snail as food stuffs by carrying out tests to determine the blood values of Liver Function Tests (LFT) parameters in Albino Wistar Rats administered with the lectin. A total of 120 samples of the Nigeria Achatina achatina snail specie were collected, authenticated at the Zoology Department of the University of Nigeria, Nsukka and 80mls of pooled crude Lectin extract was obtained. Purifications were performed on 20mls of the crude extract in three steps viz, Ammonium sulphate precipitation and Dialysis (Partial purifications), Con A Sepharose 4B affinity Chromatography column (Complete purification). The affinity purified lectin was used for all the tests conducted in this research. The crude, partially and complete/affinity purified Lectin extracts were subjected to Haemagglutination tests. The Lectin was further assessed to determine its effects on Liver Function Tests (LFT) parameters viz, Total bilirubin (TB), Conjugate bilirubin (CB), Alkaline phosphatase (ALP), Aspartate transaminase (AST) and Alanine transaminase (ALT) as follows: A total of Thirty-five (35) male Albino Wistar Rats weighing 101-180g and aged 2-3 months obtained from the Animal house of University of Nigeria, Nsukka, were used in this research. The animals were Grouped into 5 (A-E) and allowed for 2 weeks acclimatization. Graded doses of 0.04ml, 0.05ml and 0.06ml of the Affinity purified Lectin were administered intra-peritoneally to each of the rats in Groups A-D (test groups) according to their body weights at intervals of 2 days for 1 week. Group E served as the control. Two (2) mls of blood was collected from each of the rats before and 24 hours after the last day of lectin administration for the following tests: TB, CB, ALP, AST and ALT (performed by means of Roche Cobas C111 automated chemistry analyser). The results of the research showed as follows: On complete/affinity purification, 15mls of pure sample containing only the high molecular weight lectin was obtained. The respective haemagglutination tests on the crude, partially and affinity purified Lectin showed on standardization preferential agglutinations with Blood group A type. Bar charts statistics show that there was Post lectin administration mean increase in TB, CB and AST when the Post administrations values were compared with the Pre values. The Bar charts statistics show that there was Post lectin administration mean decrease in ALP and ALT. However, the differences in the Pre and Post administration mean values of these parameters were further subjected to one way analysis of variance (ANOVA) test statistics aimed at determining whether the mean increases or decreases in these assessed parameters were statistically significant. The ANOVA statistics show that the effects of the lectin on all the assessed LFT parameters viz, TB, CB, ALP, AST and ALT were statistically insignificant (P > 0.05). The results obtained in this research has succeeded in demonstrating that the A. achatina snail lectin is non-toxic, non-carcinogenic and therefore point to its nutritive value as food stuff, hence supports the snail eating education.

Abstract:

This study was conducted on an assessment of the various mitigation strategies to combat desertification in Jibia and Kaita Local Government Areas of Katsina State, Nigeria. The data use includes Satellite imageries for the study such as landsat MSS of 1976, landsat TM of 1987, SPOT XS of 1995 and landsat ETM of 2006 as well as structured questionnaires. Sixty close ended copies of the Questionnaire were administered in the study. Purposive sampling method of administering questionnaires was adopted. The percentages land mass covered for each of these variables was determined and estimated in M2. literature was obtained from various agencies which were responsible for desertification control in Katsina state. It was found from the reserved forest that in 1976 the percentage of reserved forest was 2.57%. In 1987 however, it increased by 73.9% to 76.47 %. By 1995, it declined by 9.42% to 67.05% and further declined by 0.52% in 2006. Effort to combat desertification through the use of reserved forest has been quite significant over the years. Also, noticed was a declined in shelter belt from 5.91% in 1987 to 1.097% in 1995 and a shot up to 7.39% in 2006. About 37% of the respondent opined that the deforestation leads to the disappearance of trees while 33% pinioned that it leads to reduction on agricultural productivity. The major strategy adopted to combat desertification is tree planting as supported by 88% of the respondents. It found that desertification as major environmental problem of the study area has reduced drastically from 43.34% in 1976 to 1.29% in 2006. It was also revealed from this study that some organizations such as European Economic Community/Katsina State government EEC/KTSG, Katsina Afforestation Project Unit KTAPU and Local Government Councils are the major agencies that are responsible for mitigating desertification in the study area.

Abstract:

The influence of NPK fertilizer on the population of two generalist pests, grasshopper (Zonocerus variegatus) and termites (Isoptera spp.) on some cassava varieties (Manihot esculenta Crantz), was investigated in a field trial carried out at Teaching and Research Farm of Department of Crop science, University of Nigeria, Nsukka. The treatments comprised all possible combinations of four rates of fertilizer application (0 kg/ha, 200 kg/ha, 400 kg/ha and 600 kg/ha), four improved cassava varieties (‘TMS 01-1368’, ‘TME 419’, ‘TMS 98-05-50’, ‘TMS 05 10’) and three modes of fertilizer application (Single, Split and Split-split) arranged in a factorial experiment and laid out in a randomized complete block design (RCBD). There were three replications of each treatment. Data were collected on Z. variegatus and termite incidences. In each season, incidence of Z. variegatus on cassava showed significant (p<0.05) difference among varieties. Varieties ‘TMS 01-1368’, ‘TMS 05 10,’ and ‘TMS 98-05-05,’ were significantly (p<0.05) more susceptible to the pest compared to variety ‘TME 419’. Incidence of termites on cassava differed significantly (p<0.05) among varieties in the late season and variety TMS 05 10’ was more susceptible to this pest than other varieties. Rates of NPK fertilizer had significant (p<0.05) influence on Z. variegatus incidence only. Application of various NPK fertilizer rates increased the incidence of Z. variegatus on the varieties compared to plots without fertilizer (0 kg/ha). The abundance of Z. variegatus in cassava field was influenced by fertilization and variety while termites were influenced by variety.

Abstract:

Family which is the main trust of socialization is faced with many challenges in the contemporary world. Couples no longer fancy each other. Children are in constant struggle with parents. Many marriages are experiencing either divorce, separation or face off as a result of conflict. The present study deals primarily with causes, consequences and strategies in managing family conflict and how it applies to one’s understanding of emotion and struggling of power. The study made use of descriptive survey design. The sample of the study was 300 parents from different States of the Federation on Masters and Bachelor sandwich programme in the Department Educational Foundations who offers Sociology of Education in the Faculty of Education, University of Nigeria, Nsukka drawn through random sampling technique. A 54 item Strategies for Managing Family Conflict Questionnaire (SMFCQ) developed by the researchers was used for data collection. Data collected was analyzed using mean and standard deviation. Result indicated that infertility, financial difficulties, poor communication between family members, lack of sexual satisfaction/gratification can lead to conflict in the family. Family conflicts inflict people for the course of their life and prevent them from experiencing their full potential. It causes feeling of fear, of insecurity, rejection, and guilt which may lead to the development of ill-health, separation, divorce or even death. Strategies for dealing with conflict which such as focusing on the area of interest, striving to stay positive focusing on cooperation instead of control, approaching conflict with the aim to understand, resolve and respond are identified among others. It was recommended that conflict education be giving to couples at the period of courtship.Keywords: Family; conflict; Family conflict; Emotion and Power Struggles

Abstract:

This study conducts a comparative evaluation the effect of using palm kernel oil (PKO), pure petroleum diesel and their blends (B5, B10, B20, B30, B40, and B100), on the performance of a four-cylinder CI diesel engine (David Brown 990: 58hp; 2WD), at Farm Power and Machinery Test laboratory Centre (FPMTLC), Department of Agricultural and Bioresources Engineering, University of Nigeria, Nsukka. The objective of the study was to determine the fuel consumption rates, energy expended, brake specific fuel consumption, and brake thermal efficiency, under varying operating speeds (700 – 1900rpm) at constant torque. Each fuel test was conducted using the Heenan-Froude hydraulic dynamometer engine-test-bed; pure petroleum diesel (B0) was used to generate the baseline data. Variables calculated were analyzed, then compared with each other to determine the differences in the engine performance and also to determine the optimum test fuel. The results obtained show that B10 had the overall optimum energy output, fuel consumption rates, and brake specific fuel consumption of 5431.809J, 3.42E-07 m3/s, and 0.16569l/KWh, respectively at the highest engine speed of 1900. B10 had an excellent brake thermal efficiency of 60.6% but was not better than B100, which showed a higher value of 66.95%. From the analysis, B10 is the optimum test fuel and can be used as an alternative fuel in David Brown 990 (58hp; 2WD) or similar CI diesel engines without any engine modification, even though B100 showed potential as an alternative to fossil diesel. Biofuel production grows through integrated aquaculture and algae production; the algae oil will serve as a raw material for biofuel production Keywords: Blends, Biodiesel, Brake Specific Consumption, Diesel Engine, Fuel Consumption rate, Thermal Efficiency.

Abstract:

Insolation available to dry crop on any clear-day was mathematically simulated on a local computer, using a suitable object oriented programming language (JAVA), for predicting solar radiation available at any given time in the Northern hemisphere on longitude East on Greenwich. Uyo, AkwaIbom State, Nigeria was used as a case study. The deterministic model was developed using set of equations and taking into consideration the factors of two components of solar radiation: The beam and diffused components. The results of the model rapidly produced hourly, monthly and daily data of insolation on horizontal earth surface and was verified and validated using existing solar radiation data, gotten from the Nigeria Metrological Station, Department of Geography and Regional Planning, University of Uyo, Nigeria. Predicted results showed that total solar radiation on any clear-day of the year in Uyo, Nigeria is sufficient to dry crops provided the crops are dried between the hours of 9a.m. and 4 p.m. March, April and September were found to be the best months for crop drying, while August and December recorded the lowest solar insolation.

Abstract:

This paper examines the relationship between El Nino/Southern Oscillation (ENSO) and rainfall patterns in Nigeria. Annual rainfall totals, growing season rainfall totals and annual raindays of 27 Nigerian meteorological stations with varying lengths of records from 1903 to 2012 were collected from the Nigerian Meteorological Agency (NIMET). Monthly Sea Surface Temperatures (SSTs) anomalies data over Atlantic and Pacific Oceans and Southern Oscillation Index (SOI) were obtained from Climatic Prediction Centre (CPC). Kendall tau statistics and Step-Wise Multiple Regression model were used for data analyses. Results from this study showed that annual rainfall totals, growing season rainfall and annual raindays series exhibited a significant downward trend at most of the stations over the period of the study. It was observed that annual rainfall pattern changed from a positive pattern within 1931- 1960 period to a negative pattern within 1961-1990 period and then, to a positive pattern within 1991-2012 period. It was concluded that he alternating wet and dry patterns in inter-annual rainfall fluctuations and by extension, the droughts and floods over Nigeria within the study period, were caused by sea surface temperature anomalies over the Atlantic and Pacific Oceans. The paper therefore concludes that SSTs should be integrated in the seasonal rainfall prediction models in Nigeria for an improved forecast. Oladejo, K.

Abstract:

Nigeria obtains high rate of deforestation with a loss of about 60 percent of its primary forests between 2000 and 2005 as a result of logging, subsistence agriculture, wood exploitation, and urban expansion.This research assessed the level of deforestation and how it has affected Ilorin’s microclimate and the environments. The specific objectives of this study were assessing the relationship that occurs between deforestation and microclimate, examining deforestation and the impact it has within the study area of microclimate, and forecasting the microclimate within the study area by the year 2030. The statistical tools engaged were both descriptive (mean, frequency distribution table and, bar charts) and inferential statistics (multiple regression analysis). The research indicated that there is a significant relationship between deforestation with r2 variables of 0.888 for maximum temperature, 0.201 for minimum temperature, 0.997 for precipitation, 0.43 for solar output, -0.797 and -0.873 for evapotranspiration and relative humidity respectively and Ilorin’s microclimate. The study concludes that deforestation greatly influences the microclimate of Ilorin and occurs due to human’s anthropogenic activities. Deforestation has also led to climate change.

Abstract:

Access to health care is an important component of an overall health system and a major indicator of growth. Health care planning and Geographic Information System (GIS) are two relevant fields that depend upon spatial data. GIS plays an essential role in helping public health organizations to understand population health and make decisions with the powerful tools and situation that GIS technology provides. The purpose of the study to investigated the spatial distribution of health care centers in Minna, Nigeria with a view to use Geographic Information System (GIS) technique in health care management and planning. The method is a qualitative research that is used in making decisions in order to have a strong understanding of government policies and programs. Beyond the many uses of a GIS in health applications, the greatest power of a GIS lies in its ability to integrate information from disparate sources. Traffic disturbances and poor road network were observed to be the major factors militating against effective health care facilities location in the study area.

Abstract:

Poor access to water is often linked to poverty, human welfare, health, nutritional status, and household labour. This paper is aimed at contributing to the debate surrounding water poverty in the rural areas. Primary data obtained covering water resources, access, capacity, uses, and environment were collected using closed-ended questionnaires. Altogether, 370 household heads were sampled and were selected by systematic random sampling technique. Multiple correlations, factor analysis and multiple regression methods were used to determine the level of relationship between the Water Poverty Index (WPI) components. The results revealed that: WPI is the highest in Elenke/Sagbo (72.3%) and the lowest in Onigbeti II/Sagbon (55.5%). Also, WPI has a strong positive relationship with resources (r = .656), capacity (r = .705) and environment at 95%. Percentages of explanations of WPI ranges from 86.45% in Onigbeti I to 50.99% in Aboke.The results of multiple regression between WPI and components showed that components were weak predictors in 5 wards (Onigbeti III &IV, Onigbeti II , Onigbeti I, Seriki Agbele Aboke and Abogun wards). The paper posits that access to water in Olorunsogo Local Government Area (LGA) is generally reasonable. The paper suggests stronger government presence to improve and sustain the level of access.

Abstract:

Wind speed is the principal climatic element that drives the Marmaton season in West African sub region. It drives the season by conveying huge amount of dust across the Northeastern Nigeria. The presence of dust in the atmosphere brought by the Northeast trade winds during the Harmattan season plays a vital role in absorbing and scattering solar radiation. The study examines the spatial and temporal variations of wind speed in Northeastern Nigeria during the Harmattan season with the sole aim of ascertaining its variability, patterns and trends from1984 to 2014. Descriptive and statistics such as mean, standard deviation, coefficient of variation, and time series analysis with ArcGIS 10.3 was used in examine the temporal and spatial variations of wind speed from 1984–2014 in six synoptic stations of Northeastern Nigeria. The findings show that wind speed varied both temporally and spatially in the last three decades. The pattern of variations in the six synoptic stations shows rising trends within the study years. It was also found that latitude playing a crucial role in determining the speed of the wind in the study area and as the speed of the wind increases with increasing latitude.

Abstract:

Lagos city has abundant navigable inland waterways which if fully harnessed would help minimise road traffic congestion, pollution and provide low cost means of long distance travel within the city. This study examines inland water transport services on Lagos lagoon focusing on Ikorodu-Ebutte Ero route. Primary data were obtained using structured questionnaires. While, secondary data were sourced from relevant government and private agencies. Data were analysed using descriptive techniques including frequency counts, tables and graphs. The results revealed an inadequate provision of terminal facilities and vessels in the area. It was also found that most (67.3%) of the trips via water transport in the were mainly for work purpose. In addition, low patronage was observed and it was found to be mostly due to comparatively high cost of fares and passenger safety concerns, as indicated by 67.4% and 58.7% of the respondents respectively. Furthermore, high income earners where found to patronise this mode than low income earners. The high frequency of use of water transport by the respondents (71.3% travel by water every day) indicates that, this mode has great potential of being widely adopted, if greater attention is given to its development by both the government and private sector. There is, therefore, a need for more investment in water transportation in the area through the provision of modern infrastructure and vessels.

Abstract:

The coronavirus disease 2019 (COVID-19) is caused by a new strain of coronavirus that spreads primarily by close contact. Although Nigeria adopted lockdown measures, no defined strategies were used in setting the distance threshold for these lockdowns. Hence, understanding the drivers of COVID-19 is pivotal to an informed decision for containment measures in the absence of vaccines. Spatial and temporal analyses are crucial drivers to apprehending the pattern of diseases over space and time. Thus, this study aimed to quantify the significance of distance to the temporal dynamics of COVID-19 cases in Nigeria using the Geographic Information System. Incremental spatial autocorrelation was used to analyze datasets of each month in ArcGIS. March, April, May, and June exhibited patterns with no significant peaks, while July and August exhibited patterns with two statistically significant peaks. The first and second peaks of July were 301,338.39 and 365,947.83 meters, respectively, while August was 301,338.39 and 336,128.09 meters, respectively. Therefore, a significant difference in the clustering of COVID-19 over distances between July and August was established. This indicated that progression in the spread of the virus increased the virus's spatial coverage while the distance of risk of exposure decreased. This study's findings could be utilized to establish maximum movement restriction areas to contain the spread of COVID-19.

Abstract:

This study aims to examine the variability of rainfall and temperature based on spatio-statistical analysis. Data for the study was gotten from the Nigerian Meteorological Agency and subjected to statistical analysis using mean, standard deviation, time series analysis, t-test and correlation. The results of the study revealed that the mean rainfall in the area is 108.6 mm, mean temperature is 28o C and mean sunshine is 4.7 hours. The result further revealed that mean onset date in the state is 13th march, mean cessation date is 10th October while the mean length of rainy season is 223 days. The result also showed that rainfall anomaly index in the area ranged between -2.12 and 2.28 while temperature anomaly ranged between -2.31 and 1.73. The correlation coefficient showed that cessation (0.408) and Length of rainy season (0.406) is significantly related to rainfall, sunshine hours (0.380) and Average temperature (0.867) is significantly related to minimum temperature, sunshine hours (-0.389) and average temperature (0.749) is significantly related to maximum temperature while onset (-0.642) and cessation (0.509) is significantly related to length of rainy season. However,there is a significant difference in onset dates, cessation dates and length of rainy season in the area. The area is experiencing a significant increase in temperature, rainfall and sunshine hours and recommends that more tress should be planted in the area and Nigerian meteorological agency should also inform farmers about the onset of the rains so as to help the farmers prepare for the planting season.

Abstract:

The objective of the study was to determine the effect of climate-smart integrated fertilizer management on proximate qualities and lycopene contents of three watermelon (Citrullus lanatus)varieties grown in sandy loam soil. The experiment was conducted at the experimental farm of the Department of Agricultural Education, University of Nigeria, Nsukka between the months of Augustto October 2017cropping season. The experiment was laid out in a split-plot design, with three replications, three main plots (Citrullus lanatus varieties (Sugar baby, Koalack and Charleston grey))and six sub-plots (fertilization treatments). Climate-smart integrated fertilizer considered was combination of Goat manure (GM) and Nitrogen Phosphorus PotassiumNPK15: 15: 15 fertilizer which is regarded as most nutrient-rich fertilizer with climate change mitigation and adaptation potential. The study found that the pH of the watermelon varieties were statistically similar and that Charleston grey treated with 50 kg ha-1NPK + 15 t ha-1GM had the highest interactive effect on pH value which was statistically similar with 100 kg ha-1NPK + 10 t ha-1GM treatment. It was discovered that Koalack variety had the highest moisture contents when treated with 100 kg ha-1NPK + 10 t ha-1GM, crude protein content when treated with 150 kg ha-1NPK + 5 t ha-1GM, crude fibre content when treated with 20 t ha-1GM, ether extract and total soluble solid contents when treated with 50 kg ha-1NPK + 15 t ha-1GM. For the lycopene content, it was found that Sugar baby variety had the highest mean value (0.61g/100g) when compared with Charleston grey and Koalack varieties. Sugar baby variety treated with 20t/ha-1GM had highest (0.89g/100g) interactive effect when compared with other varieties and fertilizer treatments. In conclusion, the proximate qualities and lycopene contents of the three varieties increased with the increase in the amount of GM contents of the fertilizer combinations in sandy loam soil. Climate-smart integrated fertilizer improves the proximate qualities of Koalack variety and the lycopene contents of Sugar baby variety more than in other varieties grown in the same sandy loam soil. Therefore, climate-smart integrated fertilizer is recommended for the production of the identified Citrullus lanatus varieties as a nutrition sensitive production strategy in sandy loam soils by farmers in study area.

Abstract:

Lectins are involved in recognition phenomena and their ability to bind particular Carbohydrate structures are the key to their biological functions. Bacteria typically attaches to prospective host cell membranes in receptors with lectin like sugar specificity. This is of great importance as the adherence of bacteria to host tissue surfaces is the initial event in bacterial infection. Lectins are also known to play important roles in immune system by recognizing carbohydrates that are found exclusively on pathogens, or that are inaccessible on host cells. This ability of lectins to selectively bind or agglutinate specific sugars have made them useful tools for the characterization of certain cell types or fragments, to detect cells in different states of development, to distinguish normal from tumour cells and to separate different cell types by affinity chromatography. A total of 120 samples of local Achatina achatina snail specie were collected, authenticated at the Zoology Department of the University of Nigeria, Nsukka and 80mls of pooled crude Lectin extract was obtained. Purifications were performed on 20mls of the crude extract in three steps viz, Ammonium sulphate precipitation and Dialysis (Partial purifications), Con A Sepharose 4B affinity chromatography column (Complete purification). The affinity purified lectin was used in all the tests conducted in this research. The crude, partially and complete/affinity purified lectin extracts were subjected to Haemagglutination and Protein Assay tests. The Molecular weight was deduced by Sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) method. The microbial agglutination potentials of the lectin was assessed by testing typed bacterial organisms viz, Salmonella typhimurium, Escherichia coli, Lactobacilli acidophilus, Pseudomonas aeruginosa, Staphylococcus aureus, Klebsiella aeruginosa and four typed fungal organisms: Aspergillus niger, Trichophyton mentagrophytes, Candida albicans and A. flavus. The lectin’s Lymphocyte blastogenesis activities was determined by its incubation with human lymphocytes for mitogenic stimulation assay. The results of the research showed as follows: On complete/affinity purification, 15mls of pure sample containing only the high molecular weight lectin was obtained. On standardization, the respective haemagglutination tests on the crude, partially and affinity purified lectin showed preferential agglutinations with Blood group A type. Only S. typhimurium (+++), E. coli (+) and L. acidophilus (+) reacted with the lectin but in different strengths. Incubation of the lectin with lymphocytes from human serum showed that it has the ability to stimulate lymphocytes to undergo mitosis. This research has therefore succeeded in assessing the Microbial agglutination and Lymphocyte blastogenesis potentials of the isolated and characterised A. achatina snail lectin.

Abstract:

The publication of Professor Robert L. Tignor's article ‘W. R. Bascom and the Ife bronzes' in Africa a few years ago (1990) aroused my interest, as a former student of this anthropologist, as to whether there was any further correspondence beyond what Tignor employed which would illuminate the controversy, as I felt dissatisfied with some of his interpretations. I was fortunate to have had access to Bascom's personal papers, now on file at the Phoebe Hearst Museum of Anthropology (formerly the Robert Lowie Museum of Anthropology, University of California, Berkeley), through the kind assistance of Bascom's widow, Berta Bascom, and of Frank A. Norick at the museum. The letters in the file present a somewhat different view of the role of Bascom in the matter than Tignor does. His article relies largely on US State Department archives (which do include some Bascom correspondence) and upon some published articles by Bascom, by E. H. Duckworth, then editor of Nigeria Magazine and also Nigerian Inspector of Education, and by others. The whole business of the two Ife heads which Bascom acquired throws light on the history of the gradually evolving Nigerian colonial government policy toward antiquities.

Abstract:

The operation of hydrokinetic turbine depends on river flow and pressure head (∆H) which are of high potential in many parts of Nigeria. This study attempts the analysis of the potential of the area upstream of Ikere Gorge dam for hydrokinetic potential. Soil and Water Assessment Tool (SWAT) was used to determine the hydrological parameters of the sub-basins. Pearson Moment Correlation and linear regression methods were used to find the relationships between morphometric properties and the discharge parameters. Hydrological modeling and statistical computations were done to estimate the theoretical potential of the catchment. The result shows that River Oshe has 9.542 MW, which is the highest potential while River Konsun with 1.161 MW has the lowest potential Pearson Moment Correlation shows that there is strong positive relation of 0.7 between slope and pressure head (∆H) at 0.05 significant levels. The result of the multiple regression show that hydro-geomorphic factors explained 59.1% of the variance in the explanation of hydrokinetic power potential upstream of Ikere gorge dam.

Abstract:

Insurgencies and other security challenges have caused significant setbacks for sustainable development in Kaduna state. This study assesses the role of the Kaduna state government in managing the security challenges within the state. In this study, significant factors that affects the management of security and its challenges as well as the disposing conditions were critically analyzed. The objective of the study was to examine the managerial effort of the government in tackling security challenges in Kaduna state being critical in the daily running of the state and proposed appropriate measures that could help improve the current situation. Relevant data for this study were collected from both primary and secondary sources. The study employed the exploratory research method. Indigenes of Kaduna state from different LGAs comprised the study population out of which 100 questionnaires were administered serving as sample size. The study employed descriptive statistical instruments such as frequencies and percentages in analyzing the obtained data. The study showed that majority (51.3%) of the respondents indicated that the government is the most active agent in the fight against insecurity in the state with little corroboration from other agencies. Lack of finance was observed to be the major challenge in the fight against insecurity in the state. Though, most of the state’s managerial strategies were credible, yet laudable to some extent. It was however observed that the little corroboration from other agencies such as NGOs, civil societies, traditional rulers and other security agencies played a significant role. The study therefore, recommends that a more inclusive decision-making approach between the state and other agencies be promoted to ensure cross sectional development and fight against insurgencies in the state.

Abstract:

The study demonstrated that spatial analysis with relevant socio-economic sources and physical parameter from different sources can be evaluated for the filling station sites planning. This has demonstrated the importance of Geographic Information System (GIS) application in predicting and determining of site criteria for filling stations facilities development, most especially in areas where there is land uses competition which requires consumer accessibility, sustainability, environmental safety, environmentally sensitive development solutions, etc. A stratified sampling technique was used to select the sample size and administration of the questionnaire. The data collected was analyzed using descriptive statistics such as frequency distribution, bar chart, pie chart and percentage and maps showing the sampled existing filling stations in the study area. The result shows the distribution of filling stations located across the study area. This study shows that GIS and multi-criteria analysis are essential tools to assist in correct siting to national planners and decision-makers in deciding the most appropriate filling stations location pattern to apply in Minna and its environs.

Abstract:

This study aim to attempt mapping out the Land Use or Land Cover (LULC) status of Regional Project Coordination Committee (RPCC) between 2009-2019 with a view of detecting the land consumption rate and the changes that has taken place using RS and GIS techniques; serving as a precursor to the further study on urban induced variations or change in weather pattern of the cityn Rangpur City Corporation(RCC) is the main administrative functional area for both of Rangpur City and Rangpur division and experiencing a rapid changes in the field of urban sprawl, cultural and physical landscape,city growth. These agents of Land use or Land cover (LULC) varieties are responsible for multi-dimensional problems such as traffic congestion, waterlogging, and solid waste disposal, loss of agricultural land. In this regard, this study fulfills LULC changes by using Geographical Information Systems (GIS) and Remote Sensing (RS) as well as field survey was conducted for the measurement of change detection. The sources of data were Landsat 7 ETM and landsat 8 OLI/TIRS of both C1 level 1. Then after correcting the data, geometrically and radiometrically change detection and combined classification (supervised & unsupervised) were used. The study finds LULC changes built-up area, water source, agricultural land, bare soil in a change of percentage is 17.23, 2.58, -9.94, -10.19 respectively between 2009 and 2019. Among these changes, bare soil is changed to a great extent, which indicates the expansion of urban areas is utilizing the land to a proper extent.

Abstract:

Aims: To investigate the effect of aqueous ethanolic leaf extract of this medicinal plant on isolated uterine smooth muscle strips of the rat and to determine its mechanism of action. Study Design: Laboratory-experimental design was used in this study. Place and Duration of Study: The study was carried out in the Department of Veterinary Physiology and Biochemistry of Michael Okpara University of Agriculture, Umudike, Nigeria, Department of Pharmacology and Toxicology of the Faculty of Pharmacy, University of Nigeria, Nsukka, and the Department of Veterinary Physiology and Pharmacology, University of Nigeria, Nsukka, Nigeria between June and October 2014. Methodology: Fresh leaves of Mucuna pruriens were identified and collected by a taxonomist from Nsukka, Nigeria. The leaves were then air dried and pulverized into powder. This was then subjected to cold extraction using petroleum ether (70-90) and 70% aqueous ethanol, after which the extract was left to dry at room temperature. Estrogenised uterine strips (12mm) were harvested from non-pregnant, sexually matured albino rats (180 g -250 g) and suspended in a 35ml organ bath containing Krebs’ physiological salt solution. The organ bath was connected to an isometric electronic force displacement transducer and a physiograph. Drugs such as Salbutamol, Isoprenaline, Adrenaline, Propranolol, Atipamezole and Prazosin were used as either agonists or antagonists to determine the mechanism of action of the extract. Atropine sulphate and Cyproheptadine were also used as test drugs. Concentrations of these drugs presented in the body of this work represent the final nutrient bath concentrations. Results: M. pruriens caused a dose -dependent increase in uterine muscle contraction with an EC50 of 0.88 mg/ml, n=4. The contraction was unaffected by atropine sulphate (0.042 µmol), but abolished by salbutamol (0.012-0.4 µmol), isoprenaline (0.06-0.23 µmol), and adrenaline (16 nmol). The uterine muscle contractions were enhanced by propranolol (1 µmol) in a dose- dependent manner. Prazosin (0.069-0.14 µmol) and atipamezole (3.3-13.7 nmol) were unable to abolish contractions stimulated by the extract. However, 0.2 µmol of cyproheptadine caused 80% suppression of the extract –induced uterine contraction Conclusion: It is concluded that aqueous ethanolic leaf extract of M. pruriens, has ability to cause uterine smooth muscle contraction hence, justifies its reported use traditionally as a uterine stimulant. This contraction is most likely exerted via the 5-HT receptor activation (activated by low concentrations of serotonin).

Abstract:

The wood fibre used by the paper industry originates primarily from forests. Apart from Gmelina arborea, there are other fast-growing plant species whose fibre characteristics are yet unknown. In order to relieve the pressure and demand on G. arborea, this work was aimed at characterizing and comparing the fibres of four tree species (Parkia biglobosa, Arzadirachta indica, Alstonia boonei and Cassia siamea) to G. arborea, with the intention of elucidating their suitability for the pulp and paper industry. The trunk wood samples used in this study were collected from the Botanical Garden of the University of Nigeria, Nsukka, while the study was conducted in the Plant Anatomy Laboratory in the Department of Plant Science and Biotechnology, University of Nigeria, Nsukka, Enugu State-Nigeria. The results showed that the mean fibre length ranged from 1.00 mm in P. biglobosa to 1.70 mm in A. boonei. The fibre lengths of G. arborea and A. booneidid do not vary significantly (P < 0.05). The Runkel ratio ranged from 0.624 to 3.227 across the species with G. arborea and A. boonei recording the lowest values. Conclusively, A. boonei is another pulp wood with good paper-making potential that could substitute the already known G. arborea.

Abstract:

Aims: The present study assessed the antioxidant and hepatoprotective potentials of the methanolic leaf extract of Lasimorpha senegalensis – a medicinal plant used by the indigenous people of Nigeria to treat hepatitis and feverish conditions. Place and Duration of Study: The research work was conducted in the Department of Pharmacognosy and Environmental Medicine and Department of Plant Science and Biotechnology, both in the University of Nigeria, Nsukka, from May to August, 2019. Methodology: Phytochemical analyses and acute toxicity study of the sample followed standard procedures. In vitro antioxidant assay was by DPPH and H2O2 models. A total of 25 male Wistar albino rats (120 – 150 g) were grouped into five, each group with five animals. Hepatotoxicity was induced with carbontetrachloride (1 ml/kg). The treatment groups (3-5) received extract (200 and 400 mg/kg) and Silymarin (100 mg/kg). Endogenous antioxidants (superoxide dismutase, catalase, glutathione peroxidase), plasma malondialdehyde and liver enzymes (aspartate aminotransferase, alanine aminotransferase, alkaline phosphate) were determined after treatment. Results: The results showed the leaf extract had appreciable amounts of bioactive phytochemicals and free radical scavenging activity (IC50 of 0.52 mg/ml and 0.71 mg/ml for DPPH and H2O2 respectively) with no toxicity at 5000 mg/kg. The extract also elevated the endogenous antioxidants and significantly (p ≤ .05) reduced lipid peroxidase and liver enzymes. Conclusion: This report justifies the local use of this plant in the management of various diseases related to oxidative stress and liver damage.

Abstract:

Aims: The study aims to isolate, evaluate bile tolerance and antibiogram studies of potential probiotics (Lactobacillus spp) from locally fermented Food Products (Akamu, Aqua Rafa® Yoghurt, Ogiri, Okpeye) and Kunu at Beach Market, Nsukka. Study Design: A ten - fold serial dilution and spread plate method using De Man, Rogosa and Sharpe (MRS) medium was adopted for isolation of potential Probionts. Place and Duration of Study: Department of Pharmaceutical Microbiology and Biotechnology, Faculty of Pharmaceutical Sciences, University of Nigeria Nsukka, between March - September, 2018. Methodology: Only catalase negative and Gram positive isolates characteristic of lactobacilli were used. Bile tolerance test was performed by monitoring the bacterial growth at different Bile salt concentrations (0.2%, 0.3% and 2%). The antibiogram of the isolates was assessed using the Kirby-Bauer disc diffusion method against commercial antibiotic discs of ampicillin, vancomycin, gentamycin, ciprofloxacin, methicillin and erythromycin. Results: All the 18 screened isolates were tolerant to bile salt at 0.2 % and 0.3 % with inhibition of growth at 2 % bile concentration. All isolates were observed to be resistant to methicillin (100 %) but very sensitive to gentamycin (11%) and ciprofloxacin (22%) respectively. The isolates showed intermediate resistance to other antibiotics: vancomycin (33%), erythromycin (33%) and ampicillin (44%). The decreasing pattern of resistance was thus: methicillin > ampicillin > vancomycin and erythromycin > ciprofloxacin > gentamycin. Isolates from Yoghurt (66.67%) and Ogiri (53.33%) provided most of the resistant isolates. Methicillin would provide best antagonist potential as all the isolates exhibited very high level of resistance (100 %). Conclusion: These results suggest that all the eighteen potential Lactobacillus spp strain show potential for probiotic applications and the locally fermented food products are rich sources of probionts.

Abstract:

Background. Agrochemicals are used by farmers in Southeast Nigeria to increase crop yields and food production. However, farmers are often illiterate and do not follow precautions for their usage and application, increasing the risk of exposures to humans and the environment. Objectives. The aim of the present study was to determine the extent of the use of agrochemicals by farmers, category or type used, ability to read instructions, exposure to agrochemicals during application and perception of the health effects of exposure to agrochemicals in Southeast Nigeria. Methods. From February–June 2017, a total of 200 farmers were surveyed using oral interviews and structured questionnaires. Data were analyzed using descriptive statistics. Respondents were asked about items such as socioeconomic characteristics, types and amounts of fertilizers and pesticides used, exposure during application and perceptions of the health effects of exposure to agrochemicals. Results. In the present study, the majority of farmers (74%) used inorganic fertilizers (nitrogen, phosphorus, and potassium (NPK)) and 26% used organic fertilizers (compost manure). Most of the farmers in the present study (65%) reported that they could not read agrochemical application instructions, 92% of farmers were exposed to agrochemicals during application, and most farmers (73%) reported falling sick after exposure to agrochemicals. Conclusions. We recommend that agricultural extension agents provide farmers with comprehensive training in agrochemical use to ensure their health and lower environmental risks. Participant Consent.

Abstract:

Aim: The growth and development of economically important crops are usually affected positively or negatively by the microbes present in the rhizosphere and rhizoplane. Based on this, the study was carried out to determine the fungal diversity in the rhizosphere and rhizoplane of okra plant. Methods: Okra seeds were purchased from an agricultural shop in Nsukka main market and were planted at Botanic garden, Department of Plant Science and Biotechnology, University of Nigeria, Nsukka. Physicochemical properties of the soil sample were evaluated prior to planting and as the plant aged. Rhizosphere and rhizoplane samples were collected at two weeks interval and dilution plate method was used in fungi isolation after which they were identified. The frequency of occurrence and the colony forming unit per gram of the sample (cfu/g) were evaluated. Results: The Physicochemical properties of the soil samples fluctuated as plant aged at two weeks intervals. The pH was slightly acidic to neutral which is ideal for most plant to grow. The water retention capacity, moisture content and organic matter content increased from 11.47-27.90 ml/g, 5.03-21.07% and 2.35-3.68% respectively at two weeks interval but fluctuates at subsequent weeks. A total of eleven (11) fungi were isolated from the rhizosphere and were identified as, Aspergillus niger, Aspergillus fumigatus, Aspergillus flavus, Aspergillus bertholletius, Fusarium oxysporum, Galactomyces candidum, Helminthosporium solani, Rhizopus stolonifer, Mucor racemosus, Penicillium citrinum and Trichoderma viride. All fungi were present in the rhizoplane except Aspergillus bertholletius and Penicillium citrinum. Rhizosphere had a greater number of fungi than the rhizoplane. Aspergillus species were predominant in both the rhizosphere and rhizoplane. A. niger had the highest frequency of occurrence of 58.67% on the 6th week and 65.79% on the 4th week in rhizosphere and rhizoplane respectively. The colony forming unit (cfu/g) of Aspergillus niger was significantly different from all other isolates at P≤0.001 followed by Mucor racemosus and Fusarium oxysporum with significant differences at P≤0.05 and P≤0.01 respectively. Conclusion: The rhizosphere and rhizoplane of okra plants has been shown to be rich in fungal diversity and a greater number were obtained from the rhizosphere. The data obtained from this work could be exploited by microbial ecologist to ascertain ecological associations and biomass increase by the fungal communities which also forms part of ecosystem. The fungi had no pathological effect on the plant which suggest positive effect on the growth and development of okra plant as the plant aged.

Abstract:

Although, different plant extracts have frequently been used singly and in combinations in folklore treatment of different ailments, the hidden truth behind their activity and efficacy is still to be fully scientifically established. Aim: To evaluate the effects of combined 50% methanol extracts of Euphorbia abyssinica (Desert Candle), and Coleus sp. on Candida albicans, Trichophyton mentagrophytes, Microsporum gypseum and Epidermophyton floccossum. Study Design: The completely randomised block design, two-way analysis of variance was used to analyse the data and Duncan’s New Multiple Range Test, for mean separation. Place and Duration of Study: The research was carried out in the Department of Microbiology, University of Nigeria Nsukka, Enugu State, Nigeria, between April 2011 and August 2012. Methodology: All the fungal strains used in the research were collected from the University of Nigeria Teaching Hospital Enugu, Nigeria. Susceptibility testing was done using a pour-plate method, while the checkerboard and Time-kill assays were employed to evaluate the efficacy of the different combinations of the two plant extracts. Results: The individual plant extracts inhibited all the fungal strains tested at different concentrations; but Coleus sp. extracts were observed to be more active than Euphorbia abyssinica extracts. The extract combinations inhibited the test fungi for more than two weeks. In the Time Kill assay, the combinations showed synergy on E. Floccossum only. It showed additive or antagonistic activity on the rest of the fungi tested. The Checkerboard combinations showed synergy on T. mentagrophytes, M. gypseum, and E. foccossum. Epidermophyton foccosum was the most susceptible among the fungi tested while C. albicans was the least susceptible. The control drug voriconazole also inhibited all the fungi tested. Significant antifungal activity (P=0.05) was observed in the checkerboard assay more than in the Time Kill assay. Conclusion: These findings simply authenticate some of the folklore claims that these plants have a wide range of curative uses, suggesting that they can be used as alternative sources of agents for the treatment of resistant fungal infections.
