      This study assessed the level of awareness of forestry as a profession among senior secondary school students in Ekiti State. A total of two hundred and forty pre-tested questionnaires were randomly administered to respondents to collect data in selected secondary schools in the state. The study reveal that 86.7 % and 75.8 % of the students in public and private schools respectively were aware of forestry as a course of study, while 63.3 % and 60 % of the respondents in public and private schools respectively already knew about tree planting campaigns. But only 9.2 % of the students were willing to study forestry, while career preference by the students show that Medicine was ranked first, while Forestry was ranked nineteenth with 21.2 % and 0.5 % respectively. The study recommended that Government should include forestry into the secondary school curriculum to further broaden students’ knowledge so as to increase their interest in the course.

      Biochemical changes in L. terrestris, physicochemical parameters and heavy metal contents in soil and phytoremediation quotient of Talinum triangulare were investigated. Soil samples, T. triangulare roots and stems and earthworms were obtained in two oil exploration environs (A and B) of Ugberikoko and Oton Village (control; site C) in Delta State and were subjected to chemical and biological analyses. Results obtained showed that cadmium, lead, copper, manganese, zinc, iron and nickel levels in soil were significantly (p < 0.05) higher in sites A and B compared to site C whereas arsenic and cobalt were below detection limit. The pH, nitrate, sulphate, phosphate, hardness and magnesium contents were significantly (p < 0.05) higher in sites A and B compared to site C. The heavy metal content in roots and shoots of T. triangulare were significantly (p < 0.05) higher in sites A and B compared to site C. The order of mobility and bioavailability of the metals analysed shows that Mn> Cu> Fe> Zn> Cr. Oxidative stress indicators such as MDA, GST, CAT and SOD were significantly (p < 0.05) elevated in the supernatant of earthworms from sites A and B when compared with site C whereas GSH level was significantly (p < 0.05) lowered in sites A and B compared to site C. The activity of acetylcholinesterase was significantly lowered (p < 0.05) in sites A and B compared to C. This result suggests that earthworm may be a good candidate for the assessment of soil pollution and that T. triangulare could be used for commercial and environmental friendly phytoremediation.

      Arm span (AS) has been reported to be a good substitute for height measurement in osteoskeletally deformed patients and in the elderly with osteoporosis. The aim of this study was to evaluate the relationship between arm span and height of the Itsekiris of Nigeria. The study employed a cross-sectional study design involving 300 healthy Itsekiris between the age of 20 and 70 years. The height and arm span of all volunteers were measured to the nearest centimeter. Height was measured with the subject on bare feet, feet together and with the calf, heel, buttocks and upper back touching the wall or stadiometer. The subject’s head was positioned erect with the eyes looking forward. Arm span accordingly was measured with a tape from the tip of the middle finger of one hand to the tip of the middle finger of the other hand, with the subject standing straight and back to the wall, both arms adducted to 90°. In this index, there was a weak positive correlation (0.048) which was not significant (p ≥ 0.05) between the male height and arm span, which suggested that arm span is not a good estimator of height for the male population. In the female population, there was a strong positive relationship (0.797) which was significant (p ≤ 0.001) between female height and arm span. This suggests that arm span was a good estimator of height for the females only in the population considered. Since arm span was a good predictor of height in only the female population, it is important for separate height models to be developed for each population on the account of ethnic, racial and gender differences.

      Consumer preferences for conventional cowpea characteristics using hedonic pricing have been well- studied, but these preferences are almost undocumented using conjoint analysis in discrete choice context. This study investigated the impact of educational level on consumers’ preferences and willingness to pay for white, red, black and brown conventional cowpea attributes. A conjoint choice experiment (CCE) was used to design the survey conducted at the Ahmadu Bello University (ABU), Zaria and Usmanu Danfodiyo University (UDU), Sokoto in April/May, 2010. Conditional logit consistent with random utility theory was used to analyze the stated choice data. Results reveal that high protein content is a statistically significant (P

      Despite Nigeria’s abundant fisheries resources, the country is still largely a protein deficient nation. This paper examines the technical efficiency gaps between motorised and non-motorised artisanal fishery enterprises in North Central Nigeria, with a view to identifying gaps that may help optimize the use of available inputs. Multistage sampling technique was employed in selecting 320 respondents for the study. Empirical estimate shows that the mean technical efficiency value for motorised was about 0.78 compared to non-motorised unit with 0.61. This is an indication that on the average, the fishermen were operating technical efficiency of 0.12 and 0.39 below the frontier for the motorised and non-motorised respectively. Technical inefficiency coefficient of fishing experience (-0.499) and adjusted household size (-0.256) in non-motorised unit, and motorised fishermen’s experience, education and credit coefficients (-0.783, -0.856 and -0.693) show that these variables increased technical efficiency. Government policy should be directed at educating the fishing households through skill-enhancing trainings by extension agents to adopt new innovations and techniques which will improve the fishermen’s productivity, sustainable fishery development, standard of living and apparently reduce poverty in the study area.

      The present study was undertaken to evaluate anti ulcer activity of aqueous seed and rind extracts of Citrullus lanatus (watermelon) in ethanol induced gastric ulcer model in albino rats. The experiment was divided in to two models ( A: animals pre-treated with aqueous seed extract of watermelon ; B: those per-treated with aqueous rind extract of watermelon ) in each, four groups of rats were pre-treated with distilled water (control), Ranitidine (300mg/kg) for each, 150 and 300mg/kg seed and rind extracts were given to pre-treated animals in both models. Rats pre-treated with seed and rind extracts showed significant (P˂0.05) dose-dependent decrease in gastric lesions formation. Ulcerogenesis was significantly (P˂0.05) reduced in pre-treated groups compared with control (P˂0.05). However, the per centage curative effect was effectively high in (seed 75% and rind 70%) and was also dose dependent. The result indicates that Citrullus lanatus (watermelon) seed and rind possess potential gastroprotective and antiulcerogenic activities in ethanol induced gastric ulceration. And is probably due to high citrulline and flavonoid contents which might influence both NO synthesis and antioxidant defence mechanism that cumulatively inhibit gastric acid secretion.

      In this paper, modular arithmetic is used to construct an algebraic structure. Some algebraic and number theoretic properties of the structure are enumerated. The structure is then extended by embedding a special cycle into it. A concatenation map is then defined on the extended structure and it is discovered that the extended structure is an abelian group under the concatenation map.

      Pollutants in the atmosphere are influenced by weather and chemistry thus making it difficult to know when they will concentrate and cause poor air quality. The only way to be sure of this is to monitor the air pollution at as many sites as possible and very often as well. In this study, particulate matter was captured at ten locations using SKC Air check XR5000 High volume Gravimetric sampler. The meteorological parameter was captured by LM-8000 Anemometer and with hydro thermograph -RS humidity /temperature meter .This study was conducted from May to October, 2010 in Sapele, Nigeria. The mean concentration range from156.25-850.70μg/m3 while the correlation of suspended particulate matter with wind speed and temperature were both positive and the correlation of suspended particulate matter with relative humidity was negative. It was observed that the total suspended particulate matter correlated well with relative humidity and poorly with wind speed and temperature.

      The present study examined the effect of different cooking times on total phenolics, total flavonoids, ascorbic acid content and antioxidant properties of seven tropical leafy vegetables: Pterocarpus mildbraedii, Gongronema latifolium, Ocimum gratissimum, Solanecio biafrae, Piper guineense, Celosia argentea and Solanum melongena. The thermal treatments employed were both long simmer (20 minutes at 80oC) and short simmer (5 minutes at 80oC). The result show that both short and long simmer results to a significant decrease (P< 0.05) in the ascorbic acid content in all the vegetables. There was a significant increase in the total phenol, total flavonoid, DPPH radical scavenging ability, reducing property, Fe2+ chelating ability and hydroxyl radical scavenging ability. In like manner, short simmer treatment enhances the total antioxidant activities of all the vegetables. These results suggest that although thermal treatments enhances the nutritional value of vegetables by increasing the bio-accessible phenolic content and total antioxidant activity, long simmer treatment results in the disruption of the phytochemicals constituents present. The study therefore concludes that short time simmer treatment may result to optimum yield of antioxidant activities in leafy vegetables.

      Leucas martinicensis is a medicinal plant used in traditional medicine to treat convulsions and epilepsy. The present study was to evaluate the anticonvulsant and sedative effects of the aqueous leave extract of L. martinicensis in Wistar rats. The anticonvulsant activities of L. martinicensis (50, 100, 200 or 400 mg/kg i.p.) were evaluated using maximal electroshock seizure (MES) - and strychnine (STR) -induced seizure models while the sedative properties were evaluated using the diazepam-induced sleep model in Wistar rats. The 400 mg/kg of the extract protected rats (100%) against seizures in both models while at 200 mg/kg seizure protection (100%) was only in STR model. There was a significant (p
