Abstract: Background: Challenges are detrimental to the housing project process, which has many times manifested in housing shortage in Nigeria. Nigeria's housing shortage currently stands at about 24 million deficit units. The ability to address these challenges will determine the seamless execution of the housing project process and an increase in units. To successfully mitigate housing project challenges, it becomes imperative to evaluate these challenges along the five life cycle phases so as to determine the degree of their detrimental impact, hence the aim of the study was to determine the impact of these challenges in the project process along the life cycle phases in Abuja, Nigeria...........

Abstract: Background: Male infertility is a growing world-wide problem. There are equally several causes of male infertility ranging from environmental pollutants, drugs and microbials to lifestyle changes. Cadmium is one of such environmental pollutants with adverse effect on testicular function attributed in part to oxidative stress. Development and patronage of polyherbal remedies which are said to be rich in antioxidants and have fewer side effects to treat or prevent health problems are on the increase. Superlife Total Care (STC30) is one of such polyherbal remedies. The effect of Cadmium on testicular nitric oxide homeostasis and the possible effect of STC30 are not known and hence the need for this study.........

Keywords: Cadmium, STC30, Up-regulation, nitric oxide, nitric oxide synthase.

Abstract: This study is aimed to investigate and to develop a low-cost adsorption method to remove the safranin dye from wastewater by using pine cone powders (PCP) as an adsorbent. In this method used for the removal of safranin, parameters such as adsorbate concentration, temperature, contact time at specific pH, particle size and adsorbent dose were investigated. Dye adsorption on PCP was evaluated by considering Langmuir, Freundlich, Temkin and DKR adsorption isotherm models. Various thermodynamic parameters were calculated to evaluate the adsorption processes. Adsorption kinetics were tested with pseudo-first order, pseudo- second order and intraparticle diffusion methods..

Abstract: This study was carried out to evaluate the nutritional composition of ethanol leaf-extract of Phyllanthus reticulatus collected from Abakaliki in Ebonyi State of Nigeria. The leaves were cleaned, dried and processed for analysis. Exactly 500 g of the sample was immersed in 1500 mL of absolute ethanol for 3 days and filtered afterwards. The extract was concentrated to dryness using rotary evaporator and then analyzed for proximate, vitamins and mineral compositions by standard methods. The results of proximate composition showed significantly (P.......

Abstract: The integration of technological innovations such as air quality monitoring systems, emission control technologies, and renewable energy sources has demonstrated significant potential in reducing air pollution and enhancing air quality. Policy measures, including stricter emission standards, promotion of clean and renewable energy, and improvements in public transportation, are essential for mitigating the adverse effects of air pollution. Key strategies also involve investing in carbon capture and storage technologies, supporting electric vehicle adoption, and implementing policies to reduce deforestation and promote reforestation.......

Abstract: Background: Pearl millet ranks first among cereals produced and consumed in Niger. However, its production is hampered by multiple constraints, both abiotic and biotic. Among the biotic constraints, pearl millet downy mildew disease caused by Sclerospora graminicola is one of the most destructive diseases causing losses of up to 50% in rural areas. The objective of this study is to determine the prevalence of this disease on the one hand and to assess the incidence of pearl millet downy mildew in rural areas commune of Ichirnawa on the other. Materials and Methods: A total of 100 fields in 20 administrative villages were surveyed. Five (5) fields per village were surveyed and in each field five (5) elementary plots composed of one hundred (100) pockets were materialized for the assessment of the prevalence and incidence of the disease........

Abstract: Plants are indispensable to the Earth's ecosystems, providing a wide range of ecosystem services that sustain life and promote environmental stability. These services are categorized into provisioning, regulating, supporting, and cultural services. Provisioning services include food, medicine, fiber, and fuel, which are essential for human survival and economic development. Regulating services help maintain air quality, climate stability, and water cycle regulation. Supporting services such as soil formation, pollination, and biodiversity conservation ensure the continuity of ecological processes. Cultural services contribute to human well-beingthrough aesthetic, spiritual, and educational benefits. This paper highlights the critical roles plants play in maintaining ecological balance and human welfare, emphasizing the need for conservation and sustainable utilization of plant resources.........
