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...

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...

Soil Amendment Using Poultry Manure on the Growth of Maize (Zea mays L) in Diesel Oil Contaminated Soil

ABSTRACT Experimental research on soil amendment using poultry manure on the growth of improved maize seeds (SUWAN-1-SR) in diesel oil-contaminated soil was carried out at the Research farm behind the Department of Botany, site II, Delta State University, Abraka. The experiment was laid out in Randomized Complete Block Design with four replicates. Rates of poultry manure applied were Og, 2g, 4g, 6g, 8g, and 10g. Data collected were plant height, stem girth, number of leaves, and leaf area. 

A Descriptive Analysis on the (in)fidelity of mangrove climbing sesarmid crabs to the mangrove trees in Cancabato bay, Philippines

Five years after Super Typhoon Haiyan, mangroves have regrown, and mangrove-climbing sesarmid crabs were found in Cancabato Bay. In a three-month surveillance, four species of mangrove-climbing sesarmid crabs: Aratus pisonii, Episesarma versicolor, Perisesarma bidens, and Selatium brockii were observed in mangrove trees: Avicennia marina, Aegiceras corniculatum, Rhizophora mucronata, and Rhizophora apiculata. They were observed moving into the different parts of the mangrove tree and from one...

Diel collections indicated increased species richness in seagrass associated epifaunal macroinvertebrates community

Diel patterns of epifaunal macroinvertebrates associated with seagrass beds are poorly investigated. This pattern indicated misconception in population and community dynamics, diel cycle, and overall functional activities in an ecosystem. A three-day diel sampling period was permanently established in four stations in Eastern Samar, Philippines, patterned of the same sites in an unpublished study by Pacoma, 2016. Collecting samples was done at 7:00-9:00 am and 7:00-9:00 pm, using a transect-q...

Agricultural Productivity and Yield Information System

ABSTRACT  The concept of Agriculture products and yield information system has been described as the integration and utilization of information technology system in farming related operations. Agriculture is a traditional trade and operations involved in production, having largely remained habitual in nature. Traditional methods of farming incorporated little or no use of information technology, despite its potential for dramatically increasing operations efficiency. The incorporation of inf...

Preparation of Some 4- diazo (hetero aryl)phenyl pyrazole and 2-diazo(hetero

Abstract In the present work fifty six a new α, β - unsaturated carbonyl compounds and their cyclization reactions with varieties reagent (hydrazine derivatives, hydroxylamine and thio urea) pyrazole, isoxazole and thiopyrimidine derivatives were prepared. A process of the preparation of α, β – unsaturated carbonyl compounds by coupling to diazotized a p-aminoacetophenone with 1.3 di carbonyl compounds (ethyl acetoacetate, acetyl acetone, bezoylacetone and dimedone) in presence sodium...

Determinants of Child Mortality and Morbidity in South Sudan.

ABSTRACT  The main objective of this study was to examine factors associated with childhood mortality and morbidity in South Sudan. The specific objectives were to establish childhood mortality, examine the effect of childhood factors on morbidity as well as examining the contribution of mother factors on childhood mortality and morbidity. The study used both descriptive and inferential analysis using secondary data from Second South Sudan household health survey (SSHHS2). Using univariate, ...

Four and Five Figures of Kifilideen (Power of Base 11) and Antikifilideen (Antipower of Base 11) Tables as a Tool For Mathematics Computation

The four-figure of power of base numbers of tables needs to be created for easy synchronization with the existing Logarithm table of power of base 10 which is working on four figures. Although the five-figure of power base numbers of tables are more accurate because it is having less approximation in its establishment. The four-figure table is easy to compute doing utilization because it is having less digits to work with. This paper presents the four and five figures of Kifilideen (Powe...

Health and Environmental Effects of Burning Plastic

Plastic is a material consisting of any of a wide range of synthetic or semi-synthetic organics that are malleable and can be molded into solid objects of diverse shapes. Plastics are typically organic polymers of high molecular mass, but they often contain other substances. They are usually synthetic, most commonly derived from petrochemicals, but many are partially natural (LPP, 2011). Plasticity is the general property of all materials that are able to irreversibly deform without breaking,...

Copper and Iron Distribution in Soil Profiles and Some Selected Vegetables of Saje and Sango Dump Sites

The current study was designed for determination of copper and iron and some physicochemical properties of soils collected from two selected dumpsites (Saje and Sango) in Ogun State, Nigeria by digging two depths of about 125cm. Samples were taken at different depth intervals of 25cm (i.e 0-25, 25-50, 50-75, 75-100 and 100-125cm). The soil were analyzed for physicochemical parameters such as Organic carbon, Organic matter, Soil pH, Electrical conductivity, Particle size, Cation Exhangeable Ca...
