    Opis:
    There have been disparities about the age of the Eze-Aku Formation, Anambra Basin south eastern Nigeria. Eleven surface samples of the Eze-Aku Shales from the River Obey in Umudi village, Lokpanta Abia state were subjected to standard palynological, palynofacies, kerogen preparation and analysis. A diversified palynoflora with preponderance of typical Late Cenomanian to Early Turonian diagnostic palynomorphs were recovered. Common taxa were Elaterosporites protensus, cf. Elateropollenites jardinei, Steevesipollenites binodosus, Steevesipollenites grambasti, Gnetaceaepollenites barghoornii, G. diversus, G. clathratus, Galeocornea causea, Classopollis spp., Podocarpidites herbstii, Fraxionoipollenites venustus, Cretaceaporites mulleri, Cicatricosisporites venustus, and the dinoflagellate cysts Callaiosphaeridium trycherium, Oligosphaeridium pulcherrimum, O. complex, O. albertense, Pseudoceratium pelliferum, Florentinia resex, Heterosphaeridium difficile, Surculosphaeridium longifurcatum, Cribroperidinium orthoceras and different species of Dinogymnium. Angiosperm pollens were scarce while gymnosperms were moderate due to the evolutionary trend of the flowering plants in the early Cretaceous. Structured phytoclasts with sparse amorphous organic matter which indicated deposition in nearshore to marginal marine environments dominated the palynofacies. The sporomorph colour indicated mature oil and gas generation potentials.

    Opis:
    The agricultural and environmental sectors are plagued with challenges. In agriculture, soil infertility and the subsequent quagmire of poor crop yield, has always been a major problem that limits worldwide agricultural productivity. Major environmental concerns, including Climate Change and Soil Pollution, are receiving continual attention from key stakeholders. Efforts are hence being directed at curtailing or mitigating the devastative consequences of these man-made ‘monsters’. Recently, agricultural and environmental research reveals biochar to be a veritable technology that could be used to deal with some of these concerns. Biochar has the ability to have impact upon important soil properties, such as the raising of soil pH and water holding capacity, the attraction of beneficial fungi and microbes, improvement of cation exchange capacity (CEC), induce high carbon sequestration ability and nutrient retention capacity. Moreover, its large surface area makes it a potential remedy to several identified challenges. This review, therefore, critically highlights the importance of biochar, as well as the various ways of harnessing biochar technology towards global food security and environmental sustainability.

    Opis:
    Climate change constitutes a major threat to environment and agriculture in developing countries. The study was, therefore, conducted to assess the socioeconomic characteristics of farmers’ perception of agroforestry as climate change mitigation strategy, and to determine the factors influencing agroforestry adoption as climate change mitigation strategy in the study area. A multi-stage sampling procedure was used to select 300 respondents, out of which information from 299 respondents were suitable for analysis. Data were collected by means of a structured questionnaire, and were analysed with the aid of descriptive statistics and probit modeling. Data were collected on socioeconomic characteristics of respondents and farmers’ perception of climate elements and agroforestry techniques in mitigating climate change. Results of analysis showed that farmers were in their active ages and are mostly married. Farmers also perceived that temperature and sunshine hour were on the increase, while they also perceived that agroforestry is soil fertility enhancing. Probit analysis showed that perceived soil fertility enhancement of the technology (p≤0.10), perceived drought controlling capacity of the technology (p≤0.05), farm size (p≤0.01) and membership of association (p≤0.10) were positive determinants of farmers’ adoption of agroforestry as climate change mitigation strategy in the area. The paper concludes that farmers should be encouraged to belong to farming associations, and should be educated on the importance of agroforestry in fertility enhancement and drought control.

    Opis:
    This work was aimed at investigating the metal contents of ashed and unashed shell powders of snail (Achatina fulica). The snails were collected and treated according to the American Society for Testing and Material (ASTM D482-91). Potassium (K), Sodium (Na), Calcium (Ca), Magnesium (Mg), Zinc (Zn) and Iron (Fe) in the ashed and unashed snail shell powder was determined. The result showed that the concentration of the metals in the unashed snail shell powder was higher than that of the ashed powder. The differences in the concentration of the metals was linked to the effect of ashing on the formation of silicates of the metals at high temperature (800 °C). At very high temperature, Ca (in the form of calcium carbonate) had very high concentration in both the ashed and unashed snail shell powder. This indicates that snail shell powder can be used as filler in paper industry to improve the paper opacity, or in the cosmetic industry as face powder.

    Opis:
    Vegetative propagation is any form of asexual reproduction occurring in plants in which a new plant grows from a fragment of the parent plant. Different methods of propagation can be used for plants because they respond differently. Based on plant growing uniformly, increasing the production of these plants, their resistance to pest and diseases, early bearing of fruits and having some certain traits in the new generated plants, various techniques of propagation have been designed for it. Plants can be propagated through sexual and asexual methods. Sexual one involves the use of seeds while asexual involves the vegetative parts of plant in raising new ones. The parts of the stem cutting mostly used are leaves, root, stems and terminal bud, due their simplicity. There are various trees on which stem cuttings can be done based on their maturity. It can be done on either herbaceous, hardwood, softwood or semi-hardwood due to their convenience and the stem cuttings of some more difficult to root than others. Asexual propagation involves stem cuttings, air layering, grafting, budding and micro propagation. Adoption of these forms of vegetative propagation has increased over the years and different species have been propagated through each of these methods with various degree of success. This paper aims at reviewing various techniques in propagating plant species.

    Opis:
    This research investigated the inhibition behavior of Spondias mombin leaf (SML) extracts in 0.1 M HCl solution on mild steel at various concentrations and temperatures. The result reveals that the inhibition efficiency of the extract on the mild steel sheet increases with increasing concentration of the extract and decreases with increase in temperature. Therefore, the adsorption mechanism of the extract on the mild steel surface is physical. Calculated Correlation Coefficient (R2) values show that the process follows a Freundlich adsorption isotherm. The proposed temperature coefficient equation of adsorption mechanism was found to be appropriate.

    This paper examined the numerical simulation of mud filtrate invasion process quantitatively with finite difference scheme that includes the effects of mudcake growth in oil well damage. Most of the existing models are empirical, experimental or rather complex. Efforts have been made to develop the linear flow model involving the modification of Darcy’s equation for determination of mudcake porosity-permeability and thickness through formation pressure near wellbore. The results show the effects of pressure transient on cake buildup over a considerable time intervals. Results also characterized cake parameters and time into low and high permeability zones that are strictly linear with pressure change and supercharging observed during the sensitive formation testing.

    Opis:
    Telfairia occidentalis leaves and Cucumis sativus (cucumber) are vegetables that grow best in Tropical countries like Nigeria and have good nutritional properties but are highly perishable. Both vegetables were evaluated for wine production singly and in composite forms using palm wine and Baker’s yeast strains. In addition to wine production, the vegetables were screened for phytochemicals, anti-nutrients and nutrients (proximate composition, elements and vitamins) using standard methodologies. Proximate composition (g/100g dry matter) revealed that T. occidentalis leaves had moisture content, ash, protein, fat, fibre and carbohydrate contents of 86.60±0.10, 5.72±0.02, 4.30±0.10, 0.97±0.02, 6.30±0.10 and 82.45±0.02, respectively. In contrast, Cucumis sativus had a moisture content, ash, protein, fat, fibre and carbohydrate contents of 96.75±0.01, 5.40±0.02, 13.50±0.02, 10.30±0.10, and 66.12±0.01, respectively. Both plants contained various phytochemicals, including alkaloids, glycosides, saponins, tannins, flavonoids, reducing compounds and polyphenol, but not anthraquinones and phlabotanins. However, on quantification, reducing compounds and polyphenol recorded the highest concentrations. Vitamins A and C were detected in both samples. C. sativus had high amounts of K, P, and Mg and moderate amounts of Ca, Na, Cu, Fe and Mg. T. occidentalis leaves had moderate amounts of Ca, Zn, Fe, Mg, Ca and Na. Anti-nutrients levels were all below allowable regulatory limits for vegetables. Density, pH and alcohol values ranged from 0.20 - 0.99, 0.30- 4.6 and 1.95 - 9.94%, respectively. Sensory evaluation of the wine samples showed that wine produced from 70% fluted pumpkin and 30% cucumber had the best scores in terms of acceptability, taste, aroma and appearance. Given the findings in the study, wine production using tropical vegetables could double as a viable alternative to tropical fruits and also help to curb post-harvest losses commonly experienced in the tropics.

    The main objective of this research is to determine the content of metals (Ca, Cu, Fe, Mg and Zn) and total phenols in different plant extracts of Moringa oleifera, Cassia tora, Ocimum gratissimum, Vernonia baldwinii and Telfairia occidentalis. Content were determined using Atomic Absorption Spectroscopy. The result indicate that Moringa oleifera plant extracts range from 0.25 ±0.00 to 6.13 ±0.30 mg/kg, Cassia tora plant extracts - 0.17 ±0.03 to 7.48 ±0.06 mg/kg, Ocimum gratissimum plant extracts - 0.18 ±0.00 to 5.43 ±0.12 mg/kg, Vernonia baldwinii and Telfairia occidentalis plant extracts - 0.21 ±0.03 to 7.86 ±0.12 mg/kg and 0.17 ±0.00 to 4.52 ±0.06 mg/kg, respectively. The results also revealed a lower abundance of heavy metals. The total phenolic content was determined using the modified Folin-Ciocalteu method. Herein, the phenolic content in Moringa oleifera was 8.50 ±1.23 mg Garlic Acid Equivalent g-1 (mg GAE g-1), Cassia tora - 30.00 ±0.00 mg GAE g-1, Ocimum gratissimum - 45.00 ±1.41 mg GAE g-1 , Vernonia baldwinii - 49.00 ±1.14 mg GAE g-1 and Telfairia occidentalis - 46.6 7 ±0.27 mg GAE g-1. We found the lowest total phenol content in Moringa oleifera. This also possessed high chelating activity. In contrast, Vernonia baldwinii contained the highest total phenol content, but had low chelating activity. The plant extracts with high levels of phenolic compounds exhibited good antioxidant activity.

    Opis:
    Entandrophragma angolense is a tropical tree species with a very slow growth rate. To overcome this barrier, a study on the effect of organic amendment on the growth rate of Entandrophragma angolense seedlings was conducted in the nursery section of the Department of Forestry and Wildlife, University of Benin, Benin City, Nigeria. Herein, 2kg polythene pots, each containing top soil were all amended with Poultry droppings (PRD), Cow dung (CWD) and Compost (CPT) at a ratio of 2:1, while top soil alone served as the control. Employing a completely randomized design (CRD), growth variables were recorded on a fortnight basis. The seedlings were assessed for height, number of leaves and collar diameter for a total period of 20 weeks. Fresh weights and total dry weights of the seedlings were also determined at the end of the experiment. No significant difference (p>0.05) was observed in the effect of organic amendments on the plant mean height and number of leaves throughout the study period, however, a significant difference was observed in collar diameter at 2 weeks after treatment and 12 weeks after treatment alone. Organic amendment was found to influence general biomass production in the specie, although there was no significant difference (p>0.05) in stem biomass production. Conclusively, organic amendment can be said not to have significantly (p>0.05) affected the growth of E. angolense, while this cannot be said of the biomass production, albeit at a low level of significance.

    Opis:
    Biosphere Reserves all over the world are areas that are deliberately and purposely kept to promote green economy and most importantly mitigate the effect of Global warming and climate change. The problems of climate change arise from the higher concentration of greenhouse gases in the atmosphere which exert a warming effect on the earth. Control of anthropogenic sources and greenhouse gases are constantly discussed and extensively researched in this matter, while the significance of microorganisms remained neglected. Although microorganisms has a contributory effect in global warming as in the case of methanogenes in the rumen of ruminants which has been implicated to increase the environmental methane gases during digestion, the role they play in converting greenhouse gas to useable form in the soil and water hence, reducing global warming cannot be over emphasized. The current review aimed to stress the neglected global importance of microorganisms in climate change. Overall, this review further support the key role biosphere reserves play in protecting soil and plant microorganisms in response to climate change control.

    Opis:
    The phytoplankton abundance and physico-chemical parameters of Ifewara Reservoir, Southwestern Nigeria was studied for four months (February to December, 2015). Four sampling stations (designated Stations 1-4) were established along the horizontal axis of the reservoir - from inflow region to the dam site end. At each station, net plankton samples were collected by sieving 30 litres of water through a plankton net of 50 µm mesh size into 30 ml concentrate volume. These were then preserved in 5% formalin solution and later treated with Lugol’s solution and reduced to 3 ml for microscope observation. The results of the physico-chemical parameters showed that some were above recommended limits of the National Environmental Standards and Regulations Enforcement Agencies (NESREA) for drinking water and aquatic life. Sixty-nine (69) species of phytoplankton were recorded from the four investigated sampling stations. The abundance of phytoplankton was in the following order; Bacillariophyceae (90.84%) > Chlorophyceae (44.67%) > Cyanophyceae (10.69%) > Charophyceae (0.31%) > Euglenophyceae (0.12%) > Dinophyceae (0.06%) > Chrysophyceae (0.03%). The most abundant phytoplankton species was Fragilaria aceania, accounting for 74.28% of the total, followed by Cosmarium quadrum (13.04%), Rhizoclonium hieroglyphicum (11.97%) and Oscillatoria tenuis (8.03%). With regard to the horizontal pattern of variation along the reservoir, the highest phytoplankton abundance was recorded at the inflow basin and the lowest abundance at the dam site. Almost all the phytoplankton groups also had their highest mean abundance during the rainy season rather then during the dry season.

Standard procedures were employed in all analysis. The seed oil was liquid at room temperature with percentage yield (23.65%). The oil was characterized in terms of specific gravity (0.918 g/cm3), refractive index (1.34), viscosity (26.46 X 103 poise), melting point (11-14.5 °C), moisture content (0.18%), saponification value (203.36 mg KOH/g), unsaponifiable matter (7.13%), iodine value (46.1 g/100g), peroxide value (7.5 meq/kg), free fatty acid value (18.42%), acid value (60.02 mg KOH/g) and ester value (143.34 mg KOH/g). It was also classified as non- drying (iodine value ˂115 g/100 g). The peroxide value indicates that the oil is less prone to rancidity with iodine value less than 30meq/kg. The high saponification value qualifies it for use in the manufacture of soaps and shampoos. Four classes of fatty acid were identified in the oil: palmitic acid (C16:1) (13.5 ± 0.21), stearic acid (C18:1) (6.5 ± 0.96), oleic acid (C18:1) (11.6 ± 0.62) and linoleic acid (C18:2) (68.4 ± 0.13). Linoleic acid was the most abundant fatty acid in the oil. The fatty acid content of the oil reveals that L. Siceraria seed oil could be a rich source of oil for domestic and industrial purposes if exploited.

    Opis:
    Diabetes mellitus (DM) is a group of metabolic diseases which typically presents with frequent urination, increased thirst and increased hunger. DM be classified into three main types: type I (insulin-dependent DM), type-II (non-insulin dependent DM) and type III (gestational DM). Diabetes is a group of diseases of global health significance as 382 million people worldwide had diabetes in the year 2013 and this was projected to increase to an estimated 415 million in 2015. Damage to the nerves of the body (diabetic neuropathy) is the most common complication of diabetes. The signs and symptoms of diabetic neuropathy include numbness, diminished sensation, pain etc. Various types of electrotherapy, such as transcutaneous electrical nerve stimulation (TENS), pulsed-dose electrical stimulation, frequency-modulated electromagnetic neural stimulation, have been reported effective in managing diabetic neuropathy. This study is a systematic review of the evidence to enable the determination of the effectiveness of electrical stimulation and low-intensity laser therapy (LILT), and also aid their recommendation if proven to be effective. The outcome of this study was that TENS and other forms of electrical stimulation reviewed in this study may be effective and safe non-pharmacological treatment modalities in relieving the symptoms associated with diabetic neuropathy. The effectiveness of LILT couldn’t be determined due to the different parameters used to evaluate patients’ outcome and limited number of studies. Authors recommend that further randomized controlled trials with similar methodological parameters and studies with higher quality of evidences are needed to establish the true effectiveness of these modalities in diabetic neuropathy.
