Using the proposed Elzaki projected differential transform method (EPDTM), a generalized exact solution (Solitary solution) in form of a Taylor multivariate series has been obtained; of which the highly nonlinear terms and derivatives handled by PDTM have been decomposed without expansion, computation of Adomian or He's polynomials, discretization, restriction of parameters, and with less computational work whilst achieving a highly convergent results when compared to other existing analytical/exact methods in the literature, via comparison tables, 3D plots, convergence plots and fluid-like plots. Thus showing the distinction, novelty and huge advantage of the proposed method as an asymptotic alternative, in providing generalized or solitary wave solution to a wider class of differential equations.Water is an essential component of all living things on earth and the contamination of water by heavy metals can cause detrimental health effects. This study aimed to determine the health risk posed by trace elements (Fe, Zn, Cu, Mn, Ni, Cr, Cd, Co, Pb, and As) present in the drinking water supplies of Gullele and Akaki-Kality Sub-Cities, upstream and downstream parts of Addis Ababa, respectively. The concentrations of the potentially toxic trace elements in the water samples were determined using inductively coupled plasma optical emission spectroscopy (ICP-OES). The highest concentration of the heavy metals was observed for Iron. Cadmium and cobalt were not detected in any of the tap water samples. Samples from Gullele contained higher levels of Fe and Mn, 220.3 ± 0.17 and 19.78 ± 0.08 μg/L, respectively compared to Akaki-Kality, 38.87 ± 0.14 and 2.08 ± 0.01 μg/L, respectively. Conversely, tap water from Akaki-Kality contained significantly higher levels of As than that from Gullele. Additionally, Cr and Ni were detected only in samples from Akaki-Kality, which might be due to the various industries in the area. The highest incremental lifetime cancer risk was found for arsenic, with values for children and adults in Akaki-Kality 2.50 × 10-4 and 4.50 × 10-4, respectively. Likewise, in Gullele Sub-City, it was 5.00 × 10-5 and 1.00 × 10-4 for adults and children, respectively. The results indicate that carcinogenic risk occurrence is probable from As in both studied areas.Nitrobenzene oxidation was executed utilizing an innovative method, in which Ag/Pb3O4 semiconductors irradiated by visible light were used for activation of persulfate into sulfate radicals. Batch mode experiments were accomplished to elucidate the effect of persulfate concentrations and Ag/Pb3O4 dosages on the nitrobenzene oxidation behaviors. The physicochemical properties of original and reacted Ag/Pb3O4 were illustrated by X-ray diffraction analyses, UV-Vis diffuse reflectance spectra, FE-SEM images, EDS analyses, photoluminescence spectra and X-ray photoelectron spectra, respectively. The main oxidant was hypothesized to be sulfate radicals, induced from persulfate caused by photocatalysis of Ag/Pb3O4. It was clearly reflected on the scavenging experiments with addition of benzene, ethanol and methanol individually. As far as degradation pathways concerned, nitrobenzene was essentially transformed into hydroxycyclohexadienyl radicals, and sequentially converted to 2-nitrophenol, 3-nitrophenol or 4-nitrophenol simultaneously. Denitration of nitrophenols gave rise to synthesis of phenol, followed with generation of hydroquinone and p-benzoquinone.The study examined the impact of COVID-19 on economic growth in Nigeria Opinions and attitudes. The purpose was to ascertain respondents' perception of the effect of the COVID-19 pandemic on economic growth in Nigeria. The cross-sectional survey research design was employed and a mix-method was used in collecting the research data. Content validity index and face validity served to validate the research instrument while Cronbach alpha was used to assure its reliability. The secondary data were analysed using percentage changes while the primary data were analysed using a one-sample t-test and least-squares method. Results of the respondents' opinion indicated that the COVID-19-induced lockdown has significantly constrained economic activities and the circular flow of income. Lastly, the perceived reduction in the circular flow of income in the wake of the COVID-19 lockdown has negatively impacted on economic growth in Nigeria. The need for policymakers to take drastic measures to curtail the pandemic and forestall a recession that may be consequent upon the pandemic was suggested, among others.The unstable compound octacalcium phosphate (OCP) is one of the crystalline precursors of the apatite mineral series composed by hydroxyapatite, fluorapatite and chlorapatite. The feature of OCP to react into apatite, depending on the media conditions, has been mainly exploited for biomedical applications as bone and tooth substitute material. Recently, some important applications of OCP have been documented e.g. as electrode material for supercapacitors and as fluoride remover reagent for environmental purposes. With the aim of deepening the property of OCP to be the crystalline precursor of apatite and assessing if and how the anionic competition can influence the formation of the different apatite end-members, the OCP → apatite reaction has been here investigated placing 0.223 mmol of OCP in 50 mL aqueous solution with 0.368 mmol of dissolved fluoride, chloride, hydroxyl and carbonate anions (fluoride alone, fluoride with each of the other anions, and all the anions together) at room temperature. The post-experiment analyses of solid and liquid phases, conducted by using XRD, ESEM and ICP-OES, show that fluoride is always the main anion removed from solution during the OCP transformation reaction. The precise mineralogical characterization of solid phases formed, performed using the Rietveld algorithm, shows that fluorapatite is always the main resulting apatitic phase, followed by hydroxyapatite. Taking into account the different application fields of OCP, these results could be significant in better defining the OCP → apatite reaction in aqueous solutions where different competing anions are involved.Commercial Agriculture Development is widely seen as a pathway to agriculture commercialization, poverty reduction and pro-poor growth in developing economies. Using a counterfactual approach, this study assessed the impact of the Commercial Agricultural Development Project (CADP) in Nigeria on poverty status of beneficiaries and non-beneficiaries; determine its impact on commercialization of beneficiaries and non-beneficiaries and ascertain the pro-poor impact of the Project. Data from 1199 households comprising 678 beneficiaries and 521 non-beneficiaries were used for analysis. Propensity score matching was used to select comparable observations which reduced the sample size to 1142 observations 655 beneficiaries, 487 non-beneficiaries. Data were analyzed using descriptive statistics, propensity score matching technique, Foster-Greer-Thorbecke (FGT) poverty measures, Average Treatment effect on the Treated (ATT) and Poverty equivalent growth rate (PEGR) pro-poor measure. FGT poverty indices were lower for CADP Beneficiaries than the non-beneficiaries. The impact of the CADP on poverty using the income of beneficiaries as proxy showed that those who participated in CADP had their income increased by N446,073.89 ($ 1,239.09) and were better off in terms of their welfare compared to those who did not participate in the program. For the impact on commercialization, the programme led to a statistically significant increase in the commercialization index of beneficiaries. Also the PEGR for non-beneficiaries was higher than the actual growth rate while that of beneficiaries was less than the actual growth rate implying that CADP was not pro-poor. The study concludes that even though the CADP impacted the poverty level of beneficiaries positively, it was not pro-poor hence there is a need to ensure that the poor are effectively targeted in designing development intervention programmes.The present study was conducted to assess the extent of induced genetic variability and to determine the inheritance pattern of various yield contributing phenotypic traits in M2 and M3 generations of urdbean following mutagenesis with single and combination treatments of gamma rays and ethyl methanesulphonate (EMS). The mean number of seeds per pod and 100-seed weight increased in all the mutagenic treatments in both the varieties with few exceptions in M2 generation. Proteasome inhibitor Mean pod length although increased considerably, however it did not differ significantly in most of the mutagenic treatments. In M3 generation, 0.2% EMS and 300 Gy γ rays+0.2% EMS treatments induced maximum increase in mean pod length, seeds per pod and 100-seed weight in both the varieties. Genetic parameters showed manifold increase in most of the mutagenic treatments and varied from trait to trait. Increased genetic variability for economically important traits in the selected mutant lines has successfully contributed in diversifying the accessible genetic base which could be exploited for subsequent improvement of urdbean through phenotypic selection.Reproductive decision-making and fertility patterns change with time and place, and are influenced by contemporary societal factors. In this paper, we have studied biosocial aspects of reproductive decision-making over time and generations in a Nordic setting. The aim was to explore intergenerational changes and influences on decision-making, especially regarding preconditions to first birth. Twenty-six focus group interviews were conducted in southern Sweden, including a total of 110 participants aged 17-90 years. The analysis of the interviews resulted in six themes (i) 'Providing security - an intergenerational precondition'; (ii) 'A growing smorgasbord of choices and requirements'; (iii) 'Parenthood becoming a project'; (iv) 'Stretched out life stages'; (v) '(Im)possibilities to procreate'; and (vi) 'Intergenerational pronatalism'. Our findings reflect increasing expectations on what it means to be prepared for parenthood. Despite increasing awareness of the precariousness of romantic relationships, people still wish to build new families but try to be as prepared as possible for adverse events.
