This paper studies how exchange rate policy influences households' consumption styles represented by food imports. We provide an empirical analysis based on the Malaysian annual data from 1980-2012. An autoregressivedistributedlagmodel(ARDL)wasutilizedininterpretinglongrun elasticities of food import demand as a cointegrating relation, and short-run dynamics was interpreted using ECM based on cointegrating regression of the ARDL technique. The robustness of ARDL results are verified using Dynamic OLS (DOLS) estimation technique. Our results, while providing evidence that food import demand in the country is fairly inelastic to both income growth and relative prices of food imports, also raise some important policy issues, particularly on the competitiveness of the country's agricultural and food exports.

Ethnopharmacological relevance: Five medicinal plants including Anogeissus acuminata (Roxb. ex DC.) Gills. & Perr. (Combretaceae), Catunaregam tormentosa (Bl. ex DC.) Tirveng (Rubiaceae), Dioecrescis erythroclada (Kurz) Tirveng. (Rubiaceae), Mimosa pudica Linn. var. hispida Bren. (Fabaceae), and Rauwolfia serpentina (L). Benth. ex Kurz. (Apocyanaceae), which have been traditionally used for the treatment of diabetes mellitus and other diseases for several generations by the Thai-Lanna people in the Northern part of Thailand were investigated for their hypoglycemic activity in normoglycemic and alloxan, induced diabetic mice. Materials and methods: The aqueous extracts of the selected five medicinal plants were tested for their phytochemicals, free radical scavenging activity and hypoglycemic activity on 18 h fasted normoglycemic and alloxan induced diabetic mice over a period of 4 h comparing with the standard anti-diabetic drugs (insulin and glibenclamide) using two way analysis of variance (ANOVA) as analytical tool. Phytochemical analysis was performed using the standard methods while 2,2-diphenyl-1-picrylhydrazine (DPPH) was used to test for free radical scavenging activities of the medicinal plant extracts. Results: Phytochemicals detected in the extracts were glycosides, xanthones, tannins, alkaloids and saponins. Anogeissus acuminata showed the highest free radical scavenging activity with the IC 50 value of 11.00 μg/mL which was 4 folds of the standard ascorbic acid. Significant reduction in fasting blood glucose (FBG) levels of the normoglycemic mice was observed at 4 and 3 h with the extracts of Mimosa pudica (200 mg/kg bw) and Rauwolfia serpentina (100 mg/kg bw), and percentage decreases of 46.15 and 27.94% which were 0.76 and 1.47; 0.53 and 0.91 folds of insulin and glibenclamide, respectively. In alloxan induced diabetic mice, all extracts showed significant (p < 0.05) hypoglycemic activity, with the maximum FBG reduction of 78.96 at 100 mg/kg bw shown by Anogeissus acuminata at the 4 h. The hypoglycemic activity of Anogeissus acuminata was comparable to insulin (1.1 fold), but more potent than glibenclamide (1.76 folds). Conclusions: Medicinal plants selected from the Thai/Lanna Medicinal Plant Recipe Database MANOSROI II showed hypoglycemic activity in normoglycemic and alloxan induced diabetic mice. This study confirmed the traditional use of these medicinal plants for the treatment of diabetes mellitus and the thiazolidiendiones mimic hypoglycemic effects of the medicinal plants was suggested. © 2011 Elsevier Ireland Ltd.

A two-dimensional electrical resistivity survey was carried out at the periphery of the impounding reservoir of the Ahmadu Bello University farm dam in order to investigate the subsurface seepage conditions and identify possible weak zone that could serve as seepage paths within the subsurface in the vicinity of the dam. Eight profiles were acquired, using Abem Lund imaging system, along each of the northern and southern abutment (flanks) of the reservoir. The RES2DINV interpretation software was used to analyze the data and the resulting tomograms, generally, it shows a resistivity variation from 23 to 926 ωm. Anomalous low resistivity zones within the bedrock are interpreted as zones of weakness representing preferential flow pathways for water from the impounding reservoir. © 2010 Academic Journals.

This study was conducted in Mubi area of Adamawa State, aimed at evaluating1 the use of goat milk by the rural populace as supplement to other animal protein and mineral sources. Majority of goats in Nigeria are kept under traditional system of management. In this study milk samples were collected from lactating animals (Red Sokoto goats) during the wet season (June-September, 2008), a period coinciding with forage availability and dry season (January-April, 2008) a period of feed scarcity. Analysis for fat, solid non fat, total solid, cholesterol, calcium, magnesium and phosphorus was determined according to the standard procedures described by Association of Official Analytical Chemists and Pearson's chemical analysis of food. The results obtained indicated that the goat milk has fat 5.01%, total solid 16.58%, solid non fat 11.79%, cholesterol 0.18%, calcium 0.29%, magnesium 0.15% and phosphorus 0.14%. It was concluded that milk from goats is of high nutritional values and can be used to supplement the nutritional status of the rural communities. © 2012 Academic Journals Inc.

Inhibition of steel corrosion in HCl solutions by Bromophenol blue (BPB) and Thymol blue (TB) was studied via absorbance difference measurements at 303 and 313K. The percentage inhibition efficiencies (%IE) were found to increase while corrosion rates decrease with increasing concentration in the order: 0.001M TB [37.8% (0.58 x 10-4 Add)] < 0.001MBPB [40.0 % (0.59 x 10-4 Add)]. The values of inhibition efficiencies obtained from this study show that BPB and TB inhibit steel corrosion in HCl solutions to some an appreciable extent. Inhibition of steel corrosion by BPB and TB obeyed Langmuir adsorption isotherm. From the activation energy, (Ea ≈ 6.85 kJmol-1 for BPB and Ea ≈ 6.32kJmol-1for TB) values obtained from the study, physisorption mechanism has been proposed for the inhibitors. Synergism parameter evaluated is found to be greater than unity for all concentrations of BPB and TB indicating that the enhanced inhibition efficiency of the inhibitors caused by addition of bromide ion is only due to synergism. © 2011 by ESG.

The relationship between environmental factors and human health has long been a concern among academic researchers. We use two indicators of environmental pollution, namely particulate matter (PM10) and carbon dioxide (CO2) to examine the effects of poor air quality on human mortality. This study explores an issue that has largely been ignored, particularly in the African literature, where the effect of air pollution on human mortality could be influenced by gender specification. We analyse a panel data from 35 African countries and our result suggests that the elevated levels of PM10 and CO2 have a significant effect on the increasing mortality rates in infants, under-five children and adults. Although the effect of poor air quality on adults is found to differ between genders, such difference is not statistically significant. We conclude that the air pollution effects, on average, are similar between genders in the African countries. © 2016 Springer-Verlag Berlin Heidelberg

Purification of crude biodiesel is mandatory for the fuel to meet the strict international standard specifications for biodiesel. Therefore, this paper carefully analyzed recently published literatures which deal with the purification of biodiesel. As such, dry washing technologies and the most recent membrane biodiesel purification process have been thoroughly examined. Although purification of biodiesel using dry washing process involving magnesol and ion exchange resins provides high-quality biodiesel fuel, considerable amount of spent absorbents is recorded, besides the skeletal knowledge on its operating process. Further, recent findings have shown that biodiesel purification using membrane technique could offer high-quality biodiesel fuel with less wastewater discharges. Thus, both researchers and industries are expected to benefit from the development of membrane technique in purifying crude biodiesel. As well biodiesel purification via membranes has been shown to be environmentally friendly. For these reasons, it is important to explore and exploit membrane technology to purify crude biodiesel. © 2015.

A pot experiment was conducted to study the effects of N, P and K fertilization on yield, N, P and K content and uptake by sesame. The experiment comprised 4 nitrogen rates (0, 37.5, 75, 112.5 kg N ha-1), 3 phosphorus rates (0, 22.5 & 45 kg P2O5 ha-1) and 3 rates of potassium (0, 22.5 & 45 kg K2O ha-1). Optimum number of capsule and seed yield was obtained at 75 kg N ha-1 while dry matter yield was highest at 112.5 kg N ha-1. Application of P at 45 kg P2O5 ha-1 significantly increased number of capsules, seed and dry matter yields plant-1. N fertilization at 75 kg N ha-1 increased shoot N and K content by 155 and 8%, respectively. Shoot P content increased by 3.14 folds at 37.5 kg N ha-1. P and K showed no significant influence on N and P shoot content. N fertilization enhanced N, P and K shoot uptake by 260, 43 and 46%, respectively. There was no significant increase in N and K shoot uptake during P fertilization, while P uptake was increased by 72%. K did not significantly increase N and P shoot uptake but K shoot uptake was increased by 18%. The strength of relationship between seed yield and N, P and K uptake was very strong. © 2010 Friends Science Publishers.

A field trial was conducted in 2011 rainy season to evaluate the performance of some cowpea genotypes at Mubi in the Northern Guinea Savanna ecological zone of Nigeria. The treatments consisted of five erect and semi-erect cowpea genotypes and a local cultivar (Kanannado).These were laid out in a randomized complete block design (RCBD) with three replicates. The path coefficient analysis of grain yield and yield attributes showed that number of pods per plant gave the highest percentage yield contribution of 31.85%. This was followed by plant height at 6 WAS which contributed 5.37%. The highest combined contribution of 8.66% came from pod number and 100 - grain weight. Residual percentage contribution was 49.24%. This showed that yield attributes in this study explained 50.76% of the variability in grain yield in the experimental material Furthermore ,the investigation suggests that number of pods per plant, plant height and 100 seeds weight can be considered as selection criteria in cowpea.

The geologic formation of the Gongola arm of the upper Benue trough in Northeastern Nigeria is highly heterogeneous and conglomerate that discrete classification of its satellite image will not give the required detail information about its mineralogical constituent. In this work, a fuzzy classification algorithm, the Linear Spectral Unmixing (LSU) was used to classify the image with the aim of producing detailed mineralogical map of the formation. The mineralogical units of the formation were grouped into three: sanstone/Shale/limestone, Shist/Gneiss/Migmatide and Basalt. Fractional maps, showing the relative abundance of these major units were produced. The results showed the effectiveness of LSU, a fuzzy classification technique, as the best alternative in detail mapping of a highly conglomerate and heterogeneous formation. © 2015 IEEE.
