Urbanization and Loss of Wetland in Port-Harcourt Metropolis, Nigeria

ABSTRACT Urban development in wetland ecosystems for human settlement, agriculture and industrial development is one of the biggest threats to wetland conversion and management. Prediction of future urban expansion is very useful for urban planners and environmental managers in rapidly growing cities. This study aims to examine urbanization and loss of wetland in the Port-Harcourt metropolis, using remote sensing techniques. The study analyzes land use /land cover changes (LULC) using landsa...

Dispersion Studies in River Ebere

ABSTRACT The Conventional Levenspiel and Smith fixed point continuous monitoring method is used in the evaluation of the dispersion number and the dispersion coefficient, I? of river Ebm under study. Comparisons were made with Agunwamba’s method and both methods for different results. The leverspiel and Smith method gave higher values than those obtained with the Agunwamba's method except in me station. This is due to experimental errors. The Agunwamba's method though more tedious gave mor...

Juvenile Morphological Markers for Maleness in Fluted Pumpkin (Telfairia Occidentalis Hook F.)

ABSTRACT  Six hundred seeds extracted from nine pods of fluted pumpkin (Telfairia occidentalis Hook F.) were sown in the field in 2004 and 2005 to determine the juvenile morphological markers for maleness. The results showed a significant difference (P < 0.05) between the male and female fluted pumpkin with respect to days to tendril emergence. The mean number of days to tendril emergence for the males was 19 (in 2004) and 20 (in 2005) days after planting while that of the females was 47 (in...

Effects of Addition of Carbide on Sewage Degradation

ABSTRACT  The objective of this research is to investigate the effect of addition of carbide on sewage degradation. To provide answers to the above objective, some laboratory tests were conducted which include Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total coliform, pH and Suspended Solids (SS) tests. Six experimental set ups of 5liters of sewage were constructed in the laboratory under anaerobic condition. Each of the sewage contained 0g (which served as control), 1g, ...

Simplified and Cost-Effective Method of Studying the Effect of Steel Fibers on Ultra-high Performance Concrete Specimens’ Properties/Members’ Performance

This research work, which presents a simplified technique of modelling steel fibers, uses python algorithm that can be directly run in ABAQUS to automatically generate the location and orientation of steel fibers in a rectangular ultra-high performance concrete specimen, so that the effect of steel fibers on the properties of such a specimen can be directly investigated through numerical simulation. This method is fast, can be applied to structural members of bigger dimensions (like beams,...

THE ROLE OF PARTICIPATORY COMMUNITY ENGAGEMENT IN DEVELOPMENTAL PROGRAMS(A CASE STUDY OF NAWIRI PROGRAMS IN ISIOLO COUNTY)

Community participation is the active engagement of people in solving their developmental problems and it is essential for the success of developmental programs. For community participation to happen all stakeholders need to be part and parcel of the process from the beginning to the end. The community members who are the major stakeholders should be actively involved and engaged in the order they can air out their issues and concerns to possess a meaningful impact and outcome. It is goo...

The Effect of Covid-19 Pandemic on the Operation of Private Schools: Kamukuzi Division, Mbarara City

ABSTRACTThe occurrence of COVID-19 pandemic in Uganda in March 2020 left education in a worrying situation due to the lockdown imposed by the government on all education institutions from nursery to higher institutions. Although both public and private education institutions were closed to limit the spread of covid-19 pandemic, the pandemic greatly affected the private institutions which were largely depending on the learners as their main source of income. The purpose of this study was to e...

Assessing the Impact of Competitive Intelligence on Competitive Effectiveness in the Zimbabwean Pharmaceutical Retail Sector

EXECUTIVE SUMMARY Competition is more of a war of survival than an ad-hoc business challenge [Smith, 1954]. Competitive effectiveness is important for every commercial rm, as it capacitates the rm to survive even under competitive pressure, sustain shareholder value, and the ability to guarantee a healthy return on investment. Threatened by a series of poor business results is BR Pharmacy, a small entity eking out a determined resolve to stay aoat in the highly competitive Zimbabwean pharmace...

An Investigation into the Key Influences of Consumer Buying Behaviour Towards Luxury Fashion Brands in Bulawayo

ABSTRACT Empirical studies and extant literature on factors that influence consumers into preferring expensive material goods have proliferated over the years, however no known published studies on this area have focused on luxury fashion brands. Findings from available studies emanate from the purview of expensive items such as vehicles, real estate property, and other high-end commodities. This study therefore adopts a comparative approach to examining how the influential variables observed...

An Impact Assessment of the Effect of Physical Evidence on Customers Perception of Service Quality

ABSTRACT There has been a growing trend where most Zimbabwean private hospitals are fervently investing significant material and financial resources in beautifying their service environments. The trend is largely inspired by the blanket academic assertion implying that physical evidence catalyzes customers’ positive perception of health service quality. This, they believe enables rms in the sector to charge premium rates for the actual services, and improve their bot- tom lines significantl...

Carbothermal Reduction Synthesis of Eggshell-Biochar Modified with Nanoscale Zerovalent Iron/Activated Carbon for Remediation of Soil Polluted with Lead and Cadmium

Pollution of soil with lead (Pb) and cadmium (Cd) has been gaining researchers’ attention because of their adverse health effects on the safety of the food chain and environmental health. Hence, their immobilization in the soil is of great interest to environmental scientists globally. In this study, eggshell-biochar modified with nanoscale zerovalent iron/activated carbon (ESB-nZVI/AC) were synthesized via carbothermal reduction synthesis and compared their immobilization efficiency at...

Questionnaire was administered on participants which comprised 1200 members of diverse groups drawn from three major cities; Enugu, Ibadan and Kaduna in three main ethno-geographical regions of the country using simple random and purposive sampling techniques. Data were analyzed using both descriptive and inferential statistics. The finding established a signific...

Assessment of Plant Growth Regulators and Chemicals for Potato (Solanum tuberosum L.) Dormancy Breaking and Subsequent Yield in Central Highlands of Ethiopia

The production of potato in two or more cycles within a year is increasing in the country and it is a common practice in most potato producing regions of Ethiopia. However, the characteristic long tuber dormancy of improved potato varieties in Ethiopia constrains double or triple cropping using irrigation during the long dry season of the year. Thus, it is important to break the long dormancy of tubers for early sprouting and timely planting. Therefore, several types of researches were conduc...
