There is general consensuses among scholars on the importance of international trade and foreign direct investment as a main macroeconomic variables that drive economic growth of developing countries. However, the global economic crisis plays dominant role in determining the movement of these macroeconomic variables that can change the nomenclature of economic activities in relation with trade and FDI inflow. For this purpose, this study investigates the relationship between trade openness, FDI inflow and economic growth of Nigeria by accounting for the effects of global economic crisis of 2007–2008 and commodity crisis of 2016 using Bayer and Hanck (in J Time Ser Anal 34(1):83–95, 2013) approach to cointegration and augmented autoregressive distributed lag (AARDL) method on time series data from 1982 to 2018. The results provide evidence that (1) global economic crisis significantly dampens economic growth. (2) The negative interaction of total trade, FDI and global financial economic crisis is substantive enough to dampen the trade-growth and FDI-growth led relationship. (3) The negative interaction of FDI-inflow with global economic crisis is more pronounced and substantive in the long run than the short run. This study recommends for policy option positioned towards escalating specific fiscal measure that should provide a sound legislative rules and reductions in taxes for international investors; stimulus measures targeting measures to control public spending, which had previously fuelled economic expansion.
Gamma spectrometric measurement of natural radionuclides activity concentrations by HPGe detectors was conducted in 150 agricultural soil samples collected from six states of southwestern Nigeria. The overall activity concentrations of radionuclides ranged from 15.27 to 972.00 Bqkg⁻¹ for ⁴⁰K, 0.66 to 336.19 Bqkg⁻¹ for ²³²Th and 1.32 to 123.01 Bqkg⁻¹ for ²³⁸U, with mean values of 143.95, 17.02 and 22.92 Bqkg⁻¹, respectively. The overall averages results from this study were generally lower than worldwide average value of 420, 33 and 45 Bqkg⁻¹ for ⁴⁰K, ²³⁸U and ²³²Th, respectively, thus minimal transfer to plant may be expected. The estimated radiation dose levels of the soil indicated acceptable limits for general public exposure. The radioactivity levels of ⁴⁰K, ²³²Th and ²³⁸U in the investigated agricultural soil of southwestern Nigeria are within acceptable limits. Therefore, stochastic radiological health effects of radiation exposure by farmers may not be feasible at the current moment.
This study evaluated radioactivity concentration of 40 K, 226Ra and 232Th in popular brands of commercial wall paints used in Nigeria and their associated radiological hazard indices. A NaI (Tl) detector (76 × 76 mm) was employed in the measurements. Higher mean levels of the radioactivity of 174.73, 58.18 and 56.98 Bq/kg for 40 K, 226Ra and 232Th respectively were observed in emulsion paints while oil paints gave lower values of 119.66, 44.66 and 37.86 Bq/kg for 40 K, 226Ra and 232Th respectively. From results obtained, most of the emulsion and oil paints available in Nigeria present low level of radioactivity concentration which does not pose significant radiological risk to user population. However, average excess lifetime cancer risk of these paints gave a value higher than the recommended limit. Base on this, regulation, quality control and constant monitoring of raw materials used for paint production in Nigeria is highly advised.
Prototypical n-alkyl-terminated anilino squaraines for photovoltaic applications show characteristic double-hump absorption features peaking in the green and deep-red spectral range. These signatures result from the coupling of an intramolecular Frenkel exciton and an intermolecular charge-transfer exciton. Crystalline, textured thin films suitable for polarized spectromicroscopy have been obtained for compounds with n-hexyl (nHSQ) and n-octyl (nOSQ) terminal alkyl chains. The here-released triclinic crystal structure of nOSQ is similar to the known nHSQ crystal structure. Consequently, crystallites from both compounds show equal pronounced linear dichroism with two distinct polarization directions. The difference in the polarization angle between the two absorbance maxima cannot be derived by spatial considerations from the crystal structure alone but requires theoretical modeling. Using an essential state model, the observed polarization behavior was discovered to depend on the relative contributions of the intramolecular Frenkel exciton and the intermolecular charge-transfer exciton to the total transition dipole moment. For both nHSQ and nOSQ, the contribution of the charge-transfer exciton to the total transition dipole moment was found to be small compared to the intramolecular Frenkel exciton. Therefore, the net transition dipole moment is largely determined by the intramolecular component, resulting in a relatively small mutual difference between the polarization angles. Ultimately, the molecular alignment within the microtextured crystallites can be deduced, and with that, the excited-state transitions can be spotted.
The aim of the study is to investigate the in vivo attenuation of alcohol- and cadmium chloride–induced testicular toxicity modulated by Silymarin in male Wistar rats. A total of fifty-six (56) Wistar rats were used for this study and they were randomized into seven (7) groups of eight (8) rats each. Group 1 was control rats; Groups 2–7 served as the experimental groups. After 6 weeks treatment duration, the rats were euthanized, semen was collected for semen analysis, blood samples for testosterone, and FSH and LH assay determination, and left testes was harvested for histological analysis. One-way ANOVA was used to compare means at p-level < 0.05 was considered significant. Findings from this study have shown that alcohol and cadmium chloride adversely affected semen parameters, testosterone, and FSH and LH hormone milieu. Data also showed that Silymarin administration attenuated the adverse effect of alcohol and cadmium chloride on semen quality and hormones associated with reproductive functions. Hence, Silymarin mopped the effect of in vivo attenuation of alcohol and cadmium chloride testicular damage. The findings of this study have further established that alcohol and cadmium chloride adversely affected semen parameters, testicular alterations, and serum hormonal milieu. However, the effect was more significantly deleterious in rats exposed to cadmium chloride when compared to rats exposed to alcohol, subsequently alcohol- and cadmium chloride–induced degeneration of testicular tissues. Furthermore, Silymarin administration attenuated the adverse effect of alcohol on semen quality and hormones associated with reproductive functions.
Refractivity is an important parameter in understanding radio wave propagation in the troposphere. We investigated both the monthly variations of refractivity and its trends over vegetation regions in Nigeria. Application of Matlab program was used to compute the values of radio refractivity from meteorological variables for a period 1979–2013, using ITU-R P 453-12 (The radio refractivity index; its formula and refractivity data. Recommendations and reports Geneva Switzerland, 2016) model. Results show that the pattern of radio refractivity variation at various locations in Nigeria is not the same due to the different vegetation regions. The states within the Freshwater and Rainforest regions were found to have higher refractivity values than those in the Guinea savannah, Sudan savannah and Sahel savannah regions in Nigeria. The Guinea savannah region of Nigeria (called the middle belt) has the same trend with the other parts of savannah regions in Nigeria. The only difference found is in the refractivity values. The mean refractivity values revealed that the Guinea and Sahel savannah regions have higher refractivity values than Sudan savannah region while, the Sahel savannah region has lower refractivity values than Guinea savannah region. The trends of refractivity show that refractivity increases by 0.1 N units per year in the Freshwater and Rainforest regions and decreases by 0.1 N units per year in the savannah regions of Nigeria. The average monthly value of refractivity increases from a value of approximately 356 N units in Sudan savannah region to maximum value of approximately 382 N units in Freshwater region. This indicates that the radio refractivity value increases from the savannah region to the Freshwater region of Nigeria. It was also observed that the Guinea savannah region radio refractivity values were lower than those of the Freshwater and Rainforest regions, but greater than those of the Sudan and Sahel regions. This observation is coherent with the knowledge that the Rainforests (south of the Nigeria) are more humid than the dry climates (north of the Nigeria), and so the Rainforests have greater refractivity values than the Sudan and Sahel regions. The Guinea savannah which is geographically located between these two sets of regions has moderate refractivity values.
ABSTRACT Objective: To investigate the effects of six-week cervical traction and infrared therapy on neck pain intensity (PI) and neck disability index (NDI) among individuals with cervical spondylosis. Methods: The study was a non-randomised cross-over cohort design. Forty participants (men=20, and women=20) who were purposively selected, received a six-week infrared therapy, observed a one-week washout period, and then six-week concurrent infrared therapy and cervical traction. The PI and NDI were measured at baseline, after infrared therapy, the washout period, and infrared plus cervical traction. Data were analysed using repeated-measures analysis of variance (RM ANOVA), Friedman’s ANOVA, independent samples t-test, and Kendall’s tau correlation test. Result: The mean age of the participants was 40±8.60 years. Infrared therapy plus cervical traction significantly reduced PI: χ2(3)=102.06, p< 0.001, and NDI: F (1, 39) =222.56, p<0.001, relative to infrared therapy alone. Specifically, the minimum clinically important difference (MCID) for PI was 2.2, while infrared alone reduced the PI by 1.0 (Z = 4.633, p < 0.001), infrared therapy plus cervical traction reduced PI by 6.0 (Z = 7.405, p < 0.001). The MCID for NDI was 8.50, while infrared alone reduced the NDI by 1.05 (t = 30.087, p < 0.001), infrared therapy plus cervical traction reduced NDI by 15.83 (t = 14.644, p < 0.001). Conclusion: Concurrent infrared and cervical traction significantly reduced PI and NDI among patients with cervical spondylosis more than lone infrared therapy.
Social work educators are challenged to engage students in social policy classes and inspire their interest in policy practice. Despite the profession’s ethical commitments to social justice and social and political action, there is less interest in policy practice among social work students and practitioners. This exploratory qualitative study reviews an undergraduate policy course designed as a semester-long, problem-based learning project to effect organizational policy change within students’ own campus community. The study is based on a series of student focus groups and analysis of students’ written assignments in a junior-level social policy class. Over the semester, students gained insights and skills in leadership, teaming, and policy practice. Students also identified overarching benefits including exposure to real-life policy, professional preparation, and personal investment in their projects and learning. Students were challenged by problem-based learning, particularly by the self-directed workload and time demands. Social work educators may increase students’ interest in policy practice by utilizing innovative, experiential teaching methods focused on skill development to build competence and confidence. Findings may encourage educators to apply more experiential and problem-based learning in policy classes to increase student engagement, skill development, and interest in future policy practice.
Inspired by the commitment to address the environmental challenges in Peru under the UN Sustainable Development Goals 13 (Climate Action) and its implications by 2030, therefore, this study investigates the combined role of economic globalization , financial development, and fossil fuel intensity consumption using a combination of dynamic ARDL counterfactual simulation and kernel-based regularized least squares within the context of Stochastic Impact by Regression on Population, Affluence and Technology over the period 1971-2017. This research output confirms the inverted-U-shaped hypothesis between economic growth and carbon emissions. In contrast, the kernel-based regularized least squares confirms the scale effect and fossil curse hypothesis in the relationship between financial development and carbon emission, and heterogeneous effects in economic integration and carbon emission. We further document that financial development, fossil fuel consumption , urban population, affluence (economic growth), and government final consumption expenditure spur environmental pollution while economic integration reduces it. This study recommends Peru to instill environmental justice through regulations and policies restricting inflows into an exploration of environmentally unsustainable projects within Peruvian metropolises or in the Peruvian Amazon. There is a need to revisit finance and investment laws and increase investment in low-carbon infrastructure within Peru.

This study examined Assemblies of God pastors in the USA (n = 874) on role identity, well-being, religious coping, and attitudes toward seeking professional counseling. Overall, 14.1% had depression at moderate or higher severity based on the PHQ-9 scale (score of 10 or above), with an additional 25.7% in the mild category (score of 5–9). On the Clergy Spiritual Well-Being scale, 9.2% had poor spiritual well-being in everyday life, while 18.1% showed poor spiritual well-being in ministry (score below 15 on each respective subscale). About 20% of the sample scored in the high range (above 10) on the Clergy Occupational Distress Index. Male role norms, occupational distress, and positive religious coping were predictive of help-seeking attitudes. Those who were married, younger, more highly educated, female, or had more close friends had more positive attitudes toward seeking counseling.
Rice is a major staple food consumed globally. Due to geology of the cultivated area, fertilizers inputs and planting cultural, radionuclides present in soil can be transfers to the rice grain. This can present some forms of health risk to human. Therefore, this study assessed the levels of natural radioactivity and committed effective dose due to 40K, 232Th and 238U in freshly harvested rice grains from three different paddy fields (F1, F2, and F3) in Ebonyi State, Nigeria using NaI(TI) gamma spectrometry. The average activity concentrations of 40K, 232Th and 238U in the sampled rice grains were measured to be 129.0 ± 13.0, 3.0 ± 1.3 and 11.7 ± 4.3 Bq kg–1 respectively in F1; 129.1 ± 18.5, 4.3 ± 1.6 and 8.5 ± 4.2 Bq kg–1 respectively in F2; and 89.2 ± 10.3, 4.5 ± 2.1 and 2.7 ± 1.0 Bq kg–1 respectively in F3. The total radioactivity content of the rice was attributed to 40K, contributing about 90% in F1 and 91% in both F2 and F3. The committed effective dose, estimated as 0.12, 0.11 and 0.06 mSv year–1 in the rice from F1, F2 and F3 respectively, together with the resulting cancer risks were within the acceptable limit for radiological risk. This indicates low chances of any radiological health threat to the general public upon consumption. Since the assessment is based on freshly harvested raw rice, concentrations of the radionuclides can still be modified during processing and cooking; thus the generated data of this study can serve as a valuable baseline for estimation of any modification as well as a vital reference data for the radiological food safety and policy framework of nuclear and radiation agencies and WHO/FAO in Nigeria and the rest of the world.
The level of economic growth is critical in evaluating environmental quality energy source economic growth nexus. In recent empirical works, very little attention has been given to the role of sizes of economic expansion in relation to the Environmental Kuznets Hypothesis in a panel of countries. This study, therefore, investigates the asymmetric relationships between different income groups and energy sources on the one hand with environmental quality on the other. Deviating from previous studies, this present study adopts Panel Non-Linear Autoregressive Distributed Lag (PNARDL) Model to a panel of 15 ECOWAS countries grouped into low-income and lower-middle-income countries. Results indicate that RGDP outcome for low-income nations support the EKC hypothesis when carbon footprint is used to proxy for environmental quality. Furthermore, EKC Hypothesis is also supported in lower-middle-income countries for RGDP when carbon footprint and carbon dioxide are used as proxy for environmental quality. We conclude that non-renewable energy use, harmful agricultural land practices, and unsustainable economic expansion matter so much in achieving environmental quality in the ECOWAS sub-region. Since it is considered that non-renewable energy among other energy sources influence economic activities the most, we recommend the use of renewable energy for ECOWAS sub-region in order to mitigate the damage done by fossil fuel and harmful agricultural practices in order to achieve sustainable growth and pollution-free environment.
A new series of novel dipeptide sulfonamide analogues were designed, synthesized, and screened for their in silico studies and in vivo antimalarial activities. The synthesized compounds (50 mg/Kg) showed significant activity against P. berghei (NK65) with % inhibition values in (5.9 to 64.7 %) range in when compared with reference drug, artemisinin (66.7 %) in a four day suppressive assay. The in silico studies predicted favorable binding affinity of compounds with target protein residues with high dock score against P. falciparum falcipain 2 (FP‐2) and falcipain 3 (FP‐3) proteins in comparison with the reference ligands. The synthesized compounds showed druggable properties, and the predicted (absorption, distribution, metabolism, excretion and toxicities (ADMET) properties were within the acceptable limits. Molecular dynamics simulation study of the most active compound, 8 e was performed in order to further validate the stability of the protein‐ligand complex and the protein‐ligand interactions. In this study, we synthesized and characterized new dipeptides bearing sulfonamide functionality. The protein‐ligand docking was performed to predict the binding affinity of the test compounds as possible novel antimalarial agents with inhibitory activity against P. falciparum cysteine protease FP‐2 (FP‐2) and FP‐3 (FP‐3) enzymes. And also evaluate in vivo antimalaral actvity of the dipeptide analogues.
The interconnection between environmental protection and sustainable development is at the heart of discussion among all the intergovernmental agencies around the globe. Such discussion is considered highly important considering the role of finance, an abundance of fossil fuel and industrial value-added on economic activities and environmental issues. Meanwhile, few empirical studies in this line of discussions have documented policy options for projecting the path towards sustainable development in Argentina from 1971 to 2018. To contribute to the extant literature in filling this gap, this study examines whether finance can escalate a long-lasting economic shift that will change the path of carbon emission in Argentina using the novel econometric technique, dynamic Autoregressive Distributed Lag simulations. The modelling protocol incorporates the impact of the following economic agents such as population, economic growth, trade openness, and government consumption expenditure. Our result suggests that all the variables are cointegrated under the ARDL-bounds testing framework. The long and short-term estimates from the dynamic ARDL simulation show that finance and industrial value added interestingly offer policy options for CO2 mitigation in Argentina. Fossil fuel, population, economic growth, and government consumption expenditure have increasing an impact on CO2 emissions, exacerbating sustainability challenges in Argentina. In sum, improved finance and industrial restructuring are needed economic acumen that can accelerate a quick transition to a low-carbon development in Argentina, while fossil fuel, population, economic growth, and government consumption expenditure generate environmental challenges. Policy options in consideration of investors’ safety in carbonated companies in Argentina, these companies owe shareholders an obligation to invest in a resilient carbon capture and storage technology in a bid to decrease environmental degradation and align with environmental goals set by the Argentine government.
Background Neonatal mortality has been reported as a major societal health menace across the globe. Hence, this study, which adopted a hospital-based cross-sectional type of experimental research design, aimed at examining the clinical indication of some selected cardiopulmonary and anthropometric indices as key predictive clinical biomarkers for neonatal survival. The subjects were divided into three groups; experimental Group 1 consisted of 80 pre-term neonates within 28 weeks; experimental Group 2 consisted of 80 pre-term neonates within 33 weeks; and the control group, which consisted of 80 apparently healthy, term neonates. For each subject selected, cardio-pulmonary parameters and anthropometric variables were obtained daily and compared. ANOVA, correlation coefficients, and linear regression were used to compare statistical measures. A discrimination accuracy test of previous records using cut points available from previous models was conducted for ease of estimating the possibility of neonatal survival from assayed variables. Results Following data collection, sorting, and analysis, the study found a statistically significant decrease (p < 0.05) in average systolic blood pressure (SBP) values of preterm neonates when compared with term neonates. This, however, was the reverse for DBP, which was proved to have increased in preterm neonates compared to term neonates. The study also observed a statistically significant decrease (p < 0.05) in RR and OSL levels of preterm neonates compared to term neonates. Conclusion In conclusion, cardiopulmonary and anthropometric status could be useful predictive biomarkers in clinical trials to provide insight into the extent of compromise in newborn health. This will help to minimize the death of neonates by ensuring a better treatment protocol/regimen is given. A corroborative study with an event-driven approach that assays more molecular or other non-physiological variables is recommended.
This study was designed to physiologically investigate the fate of stress related infertility conditions to focus on the regulatory response of reproductive potentials in stress-induced female Wistar rats supplemented with clomifene citrate. 42 apparently healthy female Wistar rats weighing about 120-160 g were used in the study. The animals were randomly distributed into 3 groups after acclimatization for 2 weeks. Group 1 served as the control pregnant rats not induced by restraint, mirrored and intruder stressors, group 2 consisted of rats treated with 0.013 mg/g of clomifene citrate drug and exposed to three different stressors while group 3 represented pregnant rats exposed to different stressors but not treated with clomifene citrate. At the end of 3weeks, the rats were euthanized via cervical dislocation. The uterus and ovary organs were carefully isolated, weighed and examined for histological changes. The reproductive capacities studied were gestation period, mean pup weight, litter size and survival rate respectively. Data collected is expressed in Mean±SEM and one way ANOVA statistics was used for comparison of means while Fisher's LSD was employed for post hoc test and the level of significance is determined at p-value < 0.05. Results from our study revealed that restraint and intruder stressors following supplementation with clomifene citrate produced similar stress response in the gestation length, pub-weights, litter size and percentage of survival. Stress of different nature altered the histoarchitecture of the ovary and the uteri of rats exposed to restraint or intruder stressor. Meanwhile, Clomifene citrate administration produced effect on ovulation and pregnancy outcome of stressed pregnant rats and the survival ratio of the offspring.
The study investigated the antioxidant effect of Ruzu herbal bitters (RHB) on alloxan-induced diabetic rats, the pH and the bioactive components of RHB using gas chromatography and mass spectroscopy (GC-MS). Fifty-four adult albino rats were divided into nine groups of six rats each. Group 1 was the normal control. Groups 2–6 were diabetic. Group 2 was untreated positive control, while groups 3–6 were respectively treated with 5 mg/kg b. w of glibenclamide, 0.14, 0.29 and 0.57 ml/kg b. w of RHB for 21 days. Groups 7–9 were not diabetic but treated as in groups 4–6 respectively. The results showed significant (p < 0.05) increase in the blood glucose level and significant (p < 0.05) decrease in weight in diabetic untreated group compared to the normal control. The oxidative stress parameters showed significant (p < 0.05) increases in the serum activities of superoxide dismutase (SOD) and catalase (CAT), with significant (p < 0.05) decrease in glutathione peroxidase (GPx); while there were significant (p < 0.05) increases in the levels of vitamin C (VIT C), vitamin E (VIT E), C-reactive protein (CRP) and malondialdehyde (MDA), with significant (p < 0.05) decrease in the level of glutathione (GSH) in the diabetic untreated group compared to the normal control group. However, treatment of the diabetic groups with different doses of RHB resulted in the reversal of the effects to near-normal levels in a dose-dependent manner. The pH of RHB was found to be 3.45. The GC-MS result of RHB revealed the presence of 10 bioactive compounds, out of which four are pharmacologically important antioxidants: 11-Octadecenioc acid -Methyl esther, 2,7-Dioxatricyclodeca-4, 9-diene, Cis-Z-α- Bisabolene epoxide, and Tetradecanoic acid (lauric acid). Thus, the study revealed that Ruzu herbal bitters possesses antidiabetic and antioxidant activities due to the bioactive antioxidant compounds it contains.
