Co2 ramifications involving marginal oils via market-derived requirement shocks.
On the other hand, overall satisfaction influenced revisit intention more significantly than the willingness to recommend. Overall satisfaction also partially mediated the relationships between travel motivations and revisit intention. Furthermore, the direct and indirect effects of push travel motivation were assessed in this study. this website The results of this study hold important implications for destination managers and researchers to consider the influences of motivations factors on satisfaction and behavioral intentions in their attempt to develop domestic tourism.The dynamic and growing interdependent nature of equity markets across the world has elicited the interest of investors and researchers alike. This study examines the dynamic interactions between the Nigerian stock market and selected regional and global equity markets spanning eight years, from 2011 to 2018, using daily index data. The generalised impulse response function was used alongside the Toda and Yamamoto Granger causality test to investigate the short-run dynamic linkages, while the normalized Johansen vector error correction estimates served to assess the long-run linkages given the existence of cointegration. Findings from the study revealed that the UK and the Ghanaian stock markets exert significant long-run impact on the Nigerian stock market, while vagaries from the US tend to exert more influence on the Nigerian stock market in the short-run. The study recommends that more regional efforts are needed to enhance the integration of stock markets in West Africa. The findings have implications for national and regional policymakers as well as portfolio investors.Changes in seawater chemistry due to anthropogenic uptake of CO2 by seawater results in a phenomenon termed ocean acidification. Ocean acidification has been predicted to substantially affect the exposure, behaviour, mobility and fate of toxicants with significant impacts on marine organisms. This study assessed the interactive effects of acidification and metal concentrations of Cd and Pb in the exoskeleton of the crab Dotilla fenestrata. Crabs were acutely exposed to varying concentrations of Cd (0.5, 0.75 and 1.00 mg/l), Pb (6.50, 8.50, and 10.50 mg/l) and Cd/Pb (4.50, 5.75 and 7.00 mg/l) and near-future pH of 7.2, 7.4 and 7.6 for 96 h and concentrations in the exoskeleton were analyzed using ICP-OES. Cadmium concentrations in the exoskeleton due to pH effects were in the order of 7.4 > 7.6 > 7.2, while concentrations in the exoskeleton exposed to pH 7.4 were significantly higher (ANOVA HSD df 6; p less then 0.01) compared to those of pH 7.2 and 7.6. Crabs exposed to varying Pb concentrations showed no common trend in Pb concentrations with varying pH. Concentrations of Cd and Pb in the exoskeleton of crabs exposed to combined Cd and Pb were significantly higher (ANOVA HSD df 6; p less then 0.01) at pH of 7.2 and 4.50 and 7.00 mg/l exposures. Crabs exposed to mixed metal concentrations showed elevated levels of Cd and Pb compared to those exposed to single metal due to their regulatory capacity when exposed to mixed metals.In this work, methanol decomposition method has been discussed for the production of hydrogen gas with the application of plasma. A simple dielectric barrier discharge (DBD) plasma reactor was designed for this purpose with two types of electrode. The DBD plasma reactor was experimented by substituting one of the metal electrodes with feebly conducting sea water which yielded better efficiency in producing hydrogen gas. Experimental parameters such as; discharge voltage and time were varied by maintaining a discharge gap of 1.5 mm and the plasma discharge characteristics were studied. Filamentary type micro-discharges were found to be formed which was observed as numerous streamer clusters in the current waveform. Gas chromatographic study confirmed the production of hydrogen gas with residence time around 3.6 min. Although, the concentration (%) of H2 was high (98.1 %) and consistent with copper electrode assembly, the rate of formation and concentration was found to be the highest (98.7 %) for water electrode for specific discharge voltage. The energy efficiency was found to be 0.5 mol H2/kWh and 1.2 mol H2/kWh for metal (Cu) and water electrodes respectively. The electrode material significantly affects the plasma condition and hence the rate of hydrogen production. Compositional analysis of the water used as electrode showed a minimal change in the composition even after the completion of the experiment as compared to the untreated water. Methanol degradation study shows the presence of untreated methanol in the residue of the plasma reactor which has been confirmed from the absorption spectra.This study aims to identify the steps in which users of academic libraries search for information and interact with the libraries' web interfaces. The study draws on models from the disciplines of human-computer interaction (HCI) and information-seeking behaviour (ISB) to create and investigate a Unified Model. Interpretive case studies were conducted at two universities, one in the UK and one in Kuwait. Qualitative data was collected using observations with postgraduate students and analysed by a content analysis approach. The findings revealed seven steps taken in searching for information and interacting with academic libraries' web interfaces, but these steps are overlapped as users can change, move and go from one step to another based on the difficulties they encounter and the options they have.High-value milk proteins, which can be obtained by optimized fractionation procedures, are ideal ingredients in many food applications. Thus, a simple and robust analytical method is required for the identification and quantification of these individual milk proteins. Here, we present a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method using multiple reaction monitoring (MRM) to simultaneously detect and measure target peptides of two major milk proteins, α-lactalbumin (α-LA) and β-casein (β-CN), in raw milk samples from 662 Danish Holstein cows. The MRM quantification of α-LA and β-CN was achieved with limit of detection (LOD) of 0.14 and 0.16 g/L, respectively and reproducibility of the assay less then 15%. By this newly established MRM-based method, the concentration of α-LA and β-CN in an individual cow's milk ranged from 0.5 to 1.9 (average 1.1) g/L, and from 7.5 to 23.4 (average 15) g/L, respectively. There was no significant effect of parity, whereas significantly increasing concentrations of α-LA and β-CN were observed through lactation (P less then 0.
