Malaria is a severe global public health challenge that causes significant morbidity and mortality worldwide, particularly in sub-Saharan Africa. This study was designed to determine the prevalence, parasite density, and risk factors associated with malaria infection transmission among residents of two urban communities of Ibadan, southwestern Nigeria.

A cross-sectional hospital-based study was carried out on 300 participants. Blood samples were obtained. Thick and thin blood films were prepared and viewed using the standard parasitological technique of microscopy. Moreover, data on sociodemographic and environmental variables were obtained using a pre-tested standard questionnaire.

Of the 300 participants examined, a total of 165 (55.0%) were found positive for

with a mean (S.D) parasite density of 1814.70 (1829.117) parasite/μL of blood. The prevalence and parasite density of malaria infection vary significantly (P < 0.05) with age group. Children <5 years old were more likely to have malariaducation on mosquito prevention and chemoprophylaxis before and during travel to rural areas are essential.

Malaria infection is prevalent in the study area and was greatly influenced by traveling activities from the rural areas to urban centers and vice versa. Multifaceted and integrated control strategy should be adopted. Health education on mosquito prevention and chemoprophylaxis before and during travel to rural areas are essential.Genotype by environment interaction (GxE) complicates the process of selecting genotypes suitable for quantitative traits like seed yield in beans, hence slows down the development and release of varieties by breeding programs. GxE study on seed yield in beans enables identification of stable genotypes across sites and best site(s) for discriminating the tested genotypes in terms of seed yield. The purpose of this study was to evaluate the influence of the environment, genotype, and genotype by environment interaction on seed yield stability and adaptability of common bean landraces, lines, and improved varieties across three different agro-ecologies in Tanzania. The 99 common bean genotypes (Landraces, lines, and improved varieties) were planted following alpha lattice design in three replications each contained five blocks with 20 plots. Soil properties from the experimental sites, days to 75% flowering, Seed yield, 100 seed weight, number of seeds/pod, and number of pods/plant were recorded. Data on seed yaled that E1 (TARI-Selian) was the most discriminative and representative site for common bean genotypes seed yield. Based on the yield stability index, the most stable and high seed yielding genotypes were ACC 714, Selian 14, Selian 9, Katuku, and Msolini. The identified high seed yielding and stable genotypes can be further tested in participatory variety selection involving farmers and later on released as varieties and can also be used for different breeding purposes in different agro-ecologies of Tanzania.In the present study, we depict the structural modification of test minerals, physiological response and ovarian damage in the tropical sea urchin Salmacis virgulata using microcosm CO2 (Carbon dioxide) perturbation experiment. S. virgulata were exposed to hypercapnic conditions with four different pH levels using CO2 gas bubbling method that reflects ambient level (pH 8.2) and elevated pCO2 scenarios (pH 8.0, 7.8 and 7.6). The variations in physical strength and mechanical properties of S. virgulata test were evaluated by thermogravimetric analysis, Fourier transform infrared spectroscopy, X-ray diffraction analysis and scanned electron microscopy analysis. Biomarker enzymes such as glutathione-S-transferase, catalase, acetylcholine esterase, lipid peroxidase and reduced glutathione showed physiological stress and highly significant (p less then 0.01) towards pH 7.6 and 7.8 treatments. Ovarian cells were highly damaged at pH 7.6 and 7.8 treatments. This study proved that the pH level 7.6 and 7.8 drastically affect calcification, physiological response and ovarian cells in S. virgulata.For the first time, we incorporated mesoporous micro-silica (5 μm, pore size = 50 nm) as a filler in epoxy resin aiming to enter polymer into the pore of the silica. As expected, the thermal stability of the composite increased remarkably, followed by noteworthy thermal degradation kinetics when compared to the controlled cured epoxy resin. Composites were prepared by the direct dispersion of modified nano-silica, modified mesoporous micro-silica, unmodified mesoporous micro-silica, non-porous micro-silica, and irregular micro-silica of various pore sizes as fillers in diglycidyl ether of bisphenol-A epoxy resin via ultra-sonication and shear mixing, followed by oven-curing with 4,4-diaminodiphenyl sulfone. Selleckchem Cerdulatinib DSC and TGA analyses demonstrated a higher glass transition temperature (increased by 3.65-5.75 °C) and very high activation energy for thermal degradation (average increase = 46.2%) was obtained for the same unmodified silica composite compared to pure epoxy, respectively.As the market does not offer a portable and long-lasting product combining rice and beans in a single preparation, this study intends to characterize a new and alternative gluten-free biscuit, based on the most classic Brazilian staple food rice and beans. For that, six formulations were designed to test using those ingredients as raw flours and cooked grains. One of them, formulated with wheat flour served as control. After baking, biscuits were submitted to instrumental, physicochemical, and consumer's sensory tests. Tests showed that when cooked beans substituted dried beans flour, the notes of acceptance increased and nutritional profile improved significantly (p less then 0.05), which demonstrated to be an innovative use to bakery ingredients. One of the formulations even superseded the acceptance of the control formulation. At least two of the rice and beans formulations presented physicochemical profiles close to the control, with good protein (±10 g/100g) and mineral (±5 g/100g) contents, also being a food source of fibers (±8.2 g/100g), meaning they can bring potential benefits to people on gluten-restricted diets and celiac consumers, as well as to Brazilians who could consume rice and beans, now in a new versatile way.This research aims to review the current state and limitations of water resources management in Nigeria and explore how adopting an integrated approach to water management can strengthen socio-economic development. As the support for integrated water resources management (IWRM) grows, it is necessary to explore how feasible it is in the Nigerian context especially with many Nigerian states facing water stress even with the country's substantial resources. This paper reviews literature related to the implementation of IWRM around the world with particular reference to developing countries in Africa and draws parallels between their experience and the possibilities that exist for IWRM in Nigeria. Progress on adopting IWRM in Nigeria is discussed and the pitfalls to implementing IWRM in practice are identified. Among the hindrances to effective water resources management in the country is the lack of good water governance, which has affected the quality of water legislation and institutions. This paper concludes that the slow progress of IWRM implementation in Nigeria is the result of an unclear framework for implementing IWRM in the country. This paper recommends an iterative approach to implementing IWRM that allows for adaptation and is tailored to solve specific water problems in Nigeria.There are cultural and educational barriers that hinder the adoption of technologies in educational practice. This is mainly owed to how the majority of teachers are still digital immigrants lacking adequate preparation to work in an environment of fast-paced innovation and without the corresponding updates of cognitive technology. In order to mitigate this problem, in this paper we present an alternative framework that intends to increase the effectiveness of technological application in broader educational contexts bringing together three constructs causally relating the domains of Cognitive and Motivational Competencies (CMC) - relating to people; Organisational Institutional Complexity (OIC) - educational systems and Behavioural Intentional Use of Technology (BIUT) relating to adoption of attitudes. Measurement indicators were applied to evaluate each construct in order to better predict teaching behaviour in a broader educational context. The framework evaluation was performed by two focus groups composed of experienced, highly specialised education consultants who assessed the pedagogical, technological, teacher's behaviour and overall institutional/organisational environment involving the proposed alternative solutions. The discussions and results show that participants agreed on the proposed framework's usefulness and its contributions to help teachers mediate the gaps between school and the outside world, all the while considering political and administrative barriers. The evaluators also highlight the structured motivational and self-efficacy aspects that must involve teachers and other stakeholders concerned with adopting a new social action profile for the benefit of collectives. The next work to follow this paper will be a dissemination proposal concerning the Brazilian National Educational Plan, a technological adoption that effectively meets Education's institutional principles in this country.Chrysanthemum is one of the most consumed and most valuable cut flowers worldwide. In this study, the effectiveness of three concentrations of either thyme oil (300,400 and 500 mg/l) or clove oil (150,250 and 500 mg/l) as additives in holding the postharvest solutions of chrysanthemum Arctic Queen White cut flowers were investigated. The experiments were carried out as a completely randomized design in three replicates. Many postharvest characteristics have been evaluated, such as the vase life of cut flowers, diameters of head flowers and stem, dry matter of flowers, total vase water uptake, total loss of water, relative fresh weight. Additionally, the chlorophyll contents, total sugar, and bacterial counts were determined. The results showed that the longest vase life of cut chrysanthemum was 36.50, 33.40 days, and 35.88, 31.33 days by addition of either the thyme oil (500 mg/l) or clove oil (250 mg/l) in holding solution as compared with distilled water (18.09 and 17.22 days) in both seasons. The highehemicals would be of great economic and environmental impact (Values).

Wounds are major problems of developing countries that can be managed alternatively using traditional medicinal plants. Since majority of currently available drugs for wound management are expensive and pose problems such as allergy and drug resistance, it is pivotal for the world to have intensified inquiries on the claimed medicinal plants to come up with wound healing chemicals being affordable, effective and safe. Ethiopian traditional healers recruit a wide range of medicinal plants with wound healing activities. Root bark juice of
