IMPACT OF GAS FLARING ON CLIMATE CHANGE (A CASE STUDY OF NIGER DELTA REGION OF NIGERIA)

Gas flaring is the burning of natural gas and petroleum hydrocarbons in flare stacks by upstream oil companies in oil fields during operations. Gas flaring is the most common source of global warming and contributes to emissions of carbon monoxide (CO), nitrogen (II) oxide (NO) and methane (CH4) which have the propensity of causing climate change and ecological disturbances or destruction. The study assessed the impact of gas flaring on climate change using both primary and secondary data....

Assessment of Aboveground Insects Associated Within Farm Fields of Musanze District: Abundance and Diversity

Natural pollination and the physical impairments on plant leaves, as well as plant diseases are indicators of the presence of aboveground insects. However, there is less evidence to describe the presence of such insects in Rwanda. Thus, the objective of this study was to assess the abundance of the aboveground insect species in Musanze district, in the Northern part of Rwanda. Insect traps were laid in agricultural fields ten sectors of Musanze district; Busogo, Cyuve, Gacaca, Gataraga, K...

IMPACT OF EROSION ON REAL ESTATE DEVELOPMENT IN ANGWA COMMUNITY IDAH KOGI STATE

ABSTRACT The menace of soil erosion to any settlement is a threat not only to the structures (environment) but also to human life. Soil erosion in Angwa community is a major environmental problem ravaging the community. The purpose of this study hence, is to appraise the impact of soil erosion to the community and real estate development in the community so as to suggest workable soil erosion control measures. Relevant data collected from governmental department that is from State and Local g...

Climate Change Awareness and Coping Strategies of Cocoa Farmers in Rural Ghana

The study assessed the perception of farmers on the awareness, causes and impact of climate change on their farming activities. The study further identifies and describes the various coping strategies adopted by farmers and ways of improving upon them to effectively tackle change in climatic conditions. The collected data were analyzed using descriptive statistics, such as frequencies, and percentages. The other key technique that was employed to address the objective includes the Chi squ...

Production, Optimization and Application of Printing Ink from Waste Carbon Sources

ABSTRACT  Production of carbon black from novel sources like spent automobile tyre, anthracite coal, furnace soot and graphite rod and subsequent use in the production of offset printing inks has been investigated. Carbon black from these sources were obtained by pyrolysis of shredded spent tyre and coal samples at 750-900o C in an electrical furnace, isolation of furnace carbon black and graphite rod from dry cell, drying and pulverization of the resulting samples. Acid demineralization of ...

Groundwater Chemistry and Modeling of Aquifer Depth around Uburu-Okposi Salt Lakes, South Eastern Nigeria

Abstract  The study area comprised Uburu and Okposi towns in Ohazara Local Government Area, Ebonyi state and it lies between latitudes 60 00’N and 60 05’N, and longitudes 70 44’E and 70 50’E. The area belongs to the saline hydrogeological groundwater basin of Albian Asu River Group in Cross River Basin. Three major outcrops of saline groundwater in the study area are: Umuchime- Uburu lake, Ivu-Ezizo and Amaechi-Okposi lakes. The saline lakes support long production of salts by rural ...

Effects Of Anthropogenic Actives On Tree Species Diversity in Gishwati Forest Reserve, Western, Rwanda

ABSTRACT The study in Gishwati forest Reserve aimed at determining the effect of anthropogenic activities on tree species diversity. Three areas within the forest were described as Disturbed Forest (DF), Natural forest (NF) and secondary forest (SF) in consideration of level of human disturbance. Data collection was done using plot sampling based on enumerating tree species (with a diameter at breast height ≥10 cm) within the forest, and observations to improve on validity and reliability o...

Biological Materials, Synthesized Iron Oxide Nanoparticle (Wonderful kola seeds), their Prospective Application and their Socio-economic Relevance

This research article briefly describes the experimental utilizations of plant or organic material (wonderful kola seeds) for the synthesis of iron oxide nanoparticles in a bid to understudy their applications and economic relevance. Furthermore, the characterization details were theoretically, chemically and statistically analyzed for data generation to compare with other data set, in line with nuclear applications and energy generation. Data obtained from the experimental procedure wer...

The Challenges and Impacts of Implementing Development Control Regulations in Rural Settlements of Enugu State

ABSTRACT Implementation of development control regulations has many challenges and impacts in rural Enugu State of Nigeria. This study focuses on the challenges and impacts of implementing development control regulations in rural settlements of Enugu State. Development control in rural Enugu State is ineffective due to building developers’ little or non-compliance with contravention notices served on them. The planning authorities in Enugu State have lacked the needed development control me...

Climate Model Simulation and Projections of Precipitation Changes Over West Africa

ABSTRACT Changes in precipitation characteristics have been identified to exert profound socio-economic consequences over West Africa. This study analysed climate model simulation and projections of precipitation changes over West Africa using the Norwegian Earth System Model (NorESM with Lat-Lon resolution of 1.89° by 2.5°). The skill of the model in reproducing the observed precipitation was evaluated for the present-day (1980-2005), its bias and relationship was determined using satellit...

Development of Products from Sorrel (Hibiscus Sabdariffa) and Evaluation of Their Nutrients, Phytochemicals, Antinutrients, Toxicants, Physico-Chemical, Sensory and Storage Properties

ABSTRACT The objectives of the study were to develop products from sorrel calyces, leaves and seeds, evaluate the products for nutrients, phytochemicals, antinutrients, food toxicant, physicochemical, microflora, sensory, storage properties and compare the products produced with existing products. Dry red sorrel calyces, leaves and seeds were used for the study. Pilot study was carried out to standardize recipe used for the formulation of the products. The products developed were jelly, cordi...

Impact of Torre faction on the Fuel Properties of Lignite, Coconut Shells, Cassava Peels and Their Blends

ABSTRACT The effect of torrefaction temperature and residence time on the fuel properties of lignite, biomass (coconut shells and cassava peels) and their blends was investigated. The samples were subjected to three torrecfaction temperatures (200, 260 and 300o C) and at two residence times (10 and 20 minutes) using programmable muffle furnace. Blends of torrefied lignite and biomass were prepared in two different ratios (80:20 and 70:30). The energy content, proximate and ultimate analyses o...

Boat Terminal, Port-Harcourt “A Study of Circulation”

ABSTRACT Rivers State, The ‘Treasure Base Of The Nation’ and a commercial nerve centre of the Nation has over the years been confronted with the problem of rapid growing human and vehicular traffic congestion. This problem is largely caused by the rate of rural-urban migration of people into Rivers State. In fact, recent statistics have shown that over 10,000 people enter Rivers State on a daily basis. This figure results to an estimated five million people that move around Rivers State o...
