Assessment of Heavy Metal Accumulation in Vegetables Irrigated with Water from Different Sources in Lead City University Farms, Ibadan, Nigeria
Full text linkRapid and unorganised industrialisation and urbanisation has contributed to the elevated levels of metals in the urban environment in developing countries, with attendant effect on the health and wellbeing of final consumers of such agro-products. This study was conducted to assess the amount of heavy metal accumulated by selected tropical leafyvegetablesirrigatedwith waste-waterfrom different sources; poultry waste water, Kitchen waste water and borehole water as control. The sampled vegetables used were Amaranthus hybridus, Telfaria occidentalis and Corchorus olitorus. The vegetables were grown for a period of six weeksin the screen-house of the LCU farms, Lead City University, Ibadan Oyo State, Nigeria. The vegetables were irrigated with the differentwater sources, after which the vegetable leaves were harvested and taken to the Microbiology laboratory. Elemental analysis of the vegetables was determined using the Atomic Absorption Spectro-photometer(AAS) and pH level ofthe soil and irrigationwater was assessed. The results indicated the elemental composition of the Bore-Hole Water (BHW) as (Cu=0mg/kg), (Pb=0mg/kg), (Fe=0.018 mg/kg), (Zn=0.038mg/kg) and (Mn=0.0026mg/kg); Kitchen- W a s te water (KWW) was (Cu=0178mg/kg), (Pb=0.035mg/kg), (Fe=0.023mg/kg), (Zn=0.025mg/kg) and(Mn=0.0031mg/kg) Poultry- Sewage water (PSW) is (Cu=0.029mg/kg), (Pb=0.048mg/kg), (Fe=0.0547mg/kg), (Zn=0.147mg/kg) and (Mn=0.0033mg/kg). PSW had the highest composition of heavy metals; comparing the vegetables, C. olitorius accumulated more Iron(Fe), Lead(Pb) and Copper(Cu), while T. occidentalis accumulated more Zinc (Zn) and Manganese (Mn) than A. hybridus. PSW contained substantial amount of heavy metals varying according to source while Corchorus olitorus and Telfaria occidentalis showed a high affinity for accumulation of heavy metal

The Value-Laden Nature of Technological Infrastructures: Human Influence on Technological Development and Usage
Full text linkTechnological infrastructures are often considered neutral and devoid of inherent values orethical considerations. However, this perception is misleading, as human values, choices, andinfluences deeply embed most technologies, shaping their operations and responses. The studyaims to develop an understanding of how technological system development takes place withsocial values through case studies drawn from the health care, communication, andtransportation sectors. This paper presents case studies of technological infrastructures toexplore their value-laden nature, focusing on how human decisions about technologydevelopment, deployment, and use come into being. Through a review of extant literature, itinvestigates social, ethical, and cultural values that inform technological design anddemonstrates how technologies reflect and perpetuate existing power relations, biases, andideologies. The study concludes that understanding the influence of humans on technology willbe critical to bringing equitable, inclusive infrastructural provision for more diverse services

Data were analyzed usingmean and t-test statistics at a significant level of 0.05. The findings revealed amongothers that: the edutainment group had a higher mean delay-post-test performancethan other groups notwithstanding being a day school system. It was discovered thatedutainment promoted retention in Biology students and that schooling system isnot a barrier for edutainment learning in biology. Recommendations made included: biology teachers should make adequate use of edutainment to promote retention of learning in students as this will cause a decline in examination malpractices inthe subject, school administrators and heads should put in place facilities that supports edutainment utilization by biology teachers
EFFECT OF SELF-ASSERTIVENESS STRATEGY ON THE PSYCHOLOGICAL WELLBEING OF WIDOWS IN IBADAN METROPOLIS, OYO STATE, NIGERIA
Full text linkWidowhood is a significant life event that profoundly impacts the psychological wellbeing ofwomen, particularly in African societies like Nigeria, where cultural expectations and traditionalpractices often exacerbate the challenges faced by widows.
