ABSTRACT

This study covers the investigation of the engineering properties of calcium carbide residue stabilized clay soil. It was aimed to determining the suitability of using calcium carbide residue to stabilize a clay soil to ascertain whether it can be economically for use as a construction material for sub base, bases, embankment fills. Samples were collected in angwu- pama Kaduna south local government area and laboratory test were conducted to determine the physical and geological properties of the soil. The strength of the soil had increased considerable by addition of 2%, 4% and 6% of a stabilizer (calcium carbide residue). From the analysis of result obtained in this study, the natural moisture content (NMC) of the soil is very high (i.e 34.27). the consistencies limit and the sieve analysis test result for proper classification of the soil and the effect of calcium carbide residue on the consistency limit parameter, the soil in its natural state has liquid limit of 37.00 and plasticity index of 24.84 and has about 42.9% of its entire material passing through B.S Sieve No. 200s which is accordance with AASHTO soil classification system as an A –6 soil (i.e highly clay soil) which make the soil a poor material for construction. A remarkable value of 2.37 was obtained for it specific gravity value at 0% calcium carbide residue by weight of soil. With the adding 2% – 4% calcium carbide residue, the value was decrease to 2.27 – 2.24 of soil which was the value of one of the most active soil and by adding 6% there was an increase in the value of the soil of specific gravity which was recorded to be 22.8% of clay soil and this confirm with that of lateritic soil described in BS. 1924. The compaction test show that the M.D.D and O.M.C recorded for the control sample was 1.96(g/cm3) and 22.82%. There was a decrease in value recorded with addition of the stabilizer, for consolidation test conducted, there was an increase in cv, mc, and pc value between 2%, 4% calcium carbide residue and was a drop in 6% of calcium carbide residue by rate of soil. It was found that stabilization of clay soil with 2% to 4% calcium carbide residue were the most economical and hence improves the properties of the soil.

ABSTRACT

The study analyzes extension teaching of melon farmers how improved farm practices should be used and adopted under their own individual farm location and resource availability in Yakurr Local Government Area of Cross River State. Data were collected from 76 respondents in the study area using proportional sampling techniques and the 76 respondents were picked from the list of farmers in extension agents’ list that covers the study area. Data collected were analyzed using descriptive statistics. The rankling of sources of information regarding new innovations in melon production in the study area saw extension agent (47.36%) as major source of information regarding to new technologies in melon production. The radio (22.36%), television (19.74%). friends / neighbour (9.21%) and internet / website information (1.32%) were ranked second, third, fourth and fifth respectively. The result of the test of hypothesis shows that there is significant different in yield of melon farmers that were trained by skilled extension agents and yield of melon farmers that were not trained. It was recommended that government should train more extension agents and post them to rural areas were melon farms were established this would enable more farmers to adopt innovation that would lead to increased productivities and increased standard of living in rural communities.

Abstract

In the twenty-first century, the concept of “globalization” is discouraging rather than inspirational. Many thought that it entails dominance rather than a unifying force;  globalization is perceived to affecting the daily lives of millions of people which goes  beyond the bounds of the nation state, and the authority of national governments who are  most often, unaccountable to their citizens; while the authority of nation states seems to decline, new global issues are multiplying: climate change, infectious diseases, violations of human security and human rights, terrorism, nuclear weapons, environmental destruction, economic inequality; these problems cannot be isolated from each other or solved individually; which could by directed action, may be considered as ineffective in the face of such overwhelming  inter-territorial issues, which made any  global action  too complex for fast and ready answers; it became necessary to identify one observable fact  occurring today that offers not solutions per se but a process for engagement with the most pressing problems of our contemporary world: “the emergence of global civil society”; in recent years, consciousness of global civil society has reached a crescendo in  attracting attention and anticipating influences; this is so because, it is becoming critical of the dangers of globalization, and people are grouping together in social movements, NGOs, and demonstrations to confront  these “all involving” challenges facing humanity today. In the light of the above, this essay examines Civil Society from the Historical and Theoretical Perspectives and the Limits of Global civil Society.

Abstract

Deletion operations in English are a consequence of transformation in generative grammar. The paper is developed within the framework provided by generative grammar which presents us with a set of rules that will account for the well-formed expressions of a natural language. The aim is to explain the transformations that occur in deep structure that yield the surface structure sentences that we see, read and use in the functional context. It is hoped that a good knowledge of the underlying deep structure of sentences would result in a better and deeper understanding of language and improve a speaker’s competence and performance in language use and study. The paper considers deletion operations in the areas of Wh-Deletion, Agent Deletion, Equi-NP Deletion and For Deletion, Deletion under Identity, Simple Element Deletion, Complex Element Deletion, and Multiple Element Deletion. It is further hoped that an understanding of the rules of grammar and indeed the rules of deletion operations examined in this paper will help the learner of English predict correctly which expressions are grammatical and acceptable and also help the learner explain why certain expressions are considered ill-formed and not acceptable in grammar.


TRANSNATIONAL INSURGENCY AND TERRORISM IN AFRICA: ISSUES AND TASKS FOR REGIONAL INTEGRATION

Abstract

That Africa is beleaguered is non-alarmist. Spiraling-down from Cairo to Cape, the entire region undergoes episodic crippling from the viral presence of insurgencies, xenophobic and terror groups operating with transnational morbidity. With most having questionable grievances, multiple bands of marauders intermixed with sectarians and political renegades; concertedly using asymmetric attacks and marauding tactics; thriving on wide-ranging criminality. They traverse multiple borders to merchandise crude terror, ‘acts of pure evil’, genocide and displacements; rolling back investments, cowing civilians, confounding national armies and rattling governments. The failed-state plague across Africa had predisposed these millennial menaces, setting the continent adrift. The work examines the prevalence of insecurity cropping from transnational insurgency and terrorism and its impact on African economic development and integration. The paper observes, evidentially, the stultifying of African agendas on economic development and integration (including the MDGs), with strained states U-turning from progressive governance to dissipating energies on crises management, and diverting chunk budgetary provisions into combating insecurity. As African States and Union scamper for external interventions, the myth is betrayed, again, of African solutions to African problems. These are not times for negritude. The paper proves that African integration, ab initio, was a ruse and had cusped in this pervasive insecurity. It contends, with suggested solutions, if Africa must develop and retrieve from monumental tragedy impendent of the current transnational insurgency, the task is apparently urgent. African leaders and regional integrators must reevaluate, reconceptualise, and re-strategize alongside the issues here-raised. Reasonably, the secrets of effective nation-building, regional integration and developmental futures embed in-house Africa, in committed multiple policy departures, and not in neocolonial interventions.

ABSTRACT This study was carried out to investigate theoccurrence of Listeria species in frozen, smoked and canned fish in Kaduna North Local Government Area of Nigeria. A total of one hundred and eighty (180) fish samples comprising of 60 frozen, 60 smoked and 60 canned were purchased from the fish mongers at the three major markets in Kaduna North L.G.A (Kawo, Abubakar Gumi and Unguwar Rimi markets). Sampling was done once a weekly. Listeria species were isolated using pre-enrichment selective medium and were identified by conventional biochemical tests and confirmed with Microbact ID-System. Results shows that from the 180 samples, 24 (13.3%) were found to be contaminated with Listeria species. Out of the 24 isolates, Microbact 12L –ID system showed that 9(37.5%) of L.grayi and 15 (62.5%) of L. ivanovii were positive isolates respectively. Distribution of the occurrence of Listeria spp by sample type showed that smoked fish had the highest occurrence of 19 (31.7%) when compared with frozen fish which had 5 (8.3%) whereas canned fish had 0 (0%). Distribution of Listeria isolates by location showed that Unguwar Rimi market had the highest 15 (25%) followed by Kawo market 5(8.3%) and the least contaminated was Abubakar Gumi market 4(6.6%).The prevalence of Listeria species in this study showed that there is a potential threat to health and safety of the public. Therefore it is recommended that good hygiene practices should be implemented

ABSTRACT

The study was conducted to assess management practices and perceived training needs of small ruminant farmers in southern zone of Taraba State, Nigeria. Interview schedule was used to collect data from sixty randomly selected farmers. Data was presented using descriptive statistics. Majority (68.3%) of the respondents were males. Fifty five percent of the farmers kept goats only. Majority (96.7%) kept their animal under the intensive system of management. About 63% of the respondents kept their livestock in cement block houses. Pennisetum purpureum and panicum maximum combination (61.7%) were the most commonly used forage fed to the animals. All the respondents had basic knowledge on how a healthy animal should look like. About sixty two percent indicated that diarrhea was the most frequently observed health problem in their flocks. Majority (71.7%) selected animals for breeding on the basis of fast weight gain while 65.0% on the basis of high rate of multiple births. Respondents indicated training needs in the areas of improve carcass quality (80.0%), ration formulation (75.0%), stock density (80.0%) and forage management (81.7%). Great potentials exist for small ruminant production in the area and this can be achieved through sound extension education to the farmers.
