ABSTRACT

The damaging effects of lead poisoning to various organs of the body have been severally reported; as well as the health complications they produce. There are however relatively few reports on the nature of such effects on body tissues- histology, most publications have rather addressed the resulting complications. The proper understanding of the nature of the effects of lead poisoning on body tissues could help in understating the cause of the complications and may provide insights into better ways of managing lead poisoning effects. This research investigated the effects of lead poisoning on a number of vital body tissues histology. Twelve Wistar rats were distributed into two groups: Group A being the control and Group B was administered 50mg/kg body weight of lead-in-water for a period of 28 days that the experiment lasted. The tissues were excised, fixed in formal saline and processed using the routine Haematoxylin and Eosin staining technique. Photomicrographs were obtained and analysed critically using qualitative histological principles. Lead produced observable deleterious effects on all tissues tested, the extent however vary greatly: from its extensively disruptive effects on the kidney tissues. Kidney glomeruli tubules were morphologically distorted while tubular cells show signs of assault and morphological distortions. Testis histo-architecture and epididymis epithelium were also disrupted. The spleen pulps, especially white, show sign of damage while bone marrow cells are fewer in the lead intoxicated group. Liver cells and alveolar epithelium showed signs of damage; Lead poisoning effects was observed in all the tissues.

ABSTRACT

Watermelon was used to produced jelly using pectin from different fruits (lime, lemon, orange, pineapple and grape), and jelly without the addition of pectin served as control. Physicochemical and proximate analysis were conducted on the jelly samples using standard methods, while sensory evaluated was conducted using 20 member panelists. Results showed for physicochemical: pH ranged from 3.28-3.63, TSS ranged from 60.39-67.27%, TTA ranged from 0.58-0.82%, brix content ranged from 17.53-25.78 and vitamin C ranged from 11.61-23.49. The proximate composition showed that moisture content range from 29.50 to 38.64%, ash ranged from 1.03 to 0.96%, crude protein ranged from 0.84 to 1.09%, crude fats ranged from 1.09 to 0.62%, the total solids ranged from 38.64 to 70.48%, carbohydrate ranged from 59.21 to 67.66% while crude fibre showed no value. Sensory evaluation showed that all the samples were acceptable to the panelists with respect to overall acceptability. The work also revealed that fruit waste can be utilized in jelly production.

ABSTRACT                                                                                                                                                                                                                  The study examines environmental problems and adverse impacts on the health of urban households in the Lafia metropolitan area, Nigeria. The results showed that majority (50%)of the respondents in Tudun-kauri disposed solid waste in open dumps and allow it to decompose naturally while (24.8%) others use burning as the way of disposed their solid wastes. Poor handling, evacuation and disposal of waste have numerous negative impacts on the environment such as proliferation of mosquitoes and flies, bad odour, visual pollution. These negatives impacts on the environment in turn have negatives impacts on the health of the residents. Dysentery and diarrhea (81%) appears the most encountered disease followed by Malaria (78%) and cough and sore throat(36%) among others. The major causes for the inefficient solid waste management systems in Lafia are the lack of social awareness/ community involvement and sound legislative policy. There is a need for greater government involvement, community participation and orientation with private sectors involvement in waste management in Lafia with a view to building capacity for effective delivery of waste management services and ultimately improve the sanitary state of the city thereby reducing preventable disease burden on the populace as. It is recommended that Nasarawa State environmental protection agency (NSEPA) should introduce house to house sanitary inspection, monthly environmental sanitation with strict penalty against defaulters. Other recommendations if strictly put to use, it will go a long way reducing the menace posed by solid wastes to human health and his environment.

ABSTRACT

Tourism is defined by World Tourism Organization (WATO), as activities that involve people travelling from their usual places of abode to other locations outside their normal environment. The travel must not be more than one consecutive year for leisure, business and other purposes’. While architecture, as defined by Dictionaary.com (n.d), is ‘the profession of designing buildings, open areas, communities, and other artificial constructions and environments, with regards to aesthetics’. Architecture is an essential ingredient of most if not all tourism experiences, framing the holiday experience and being a tourism attraction at the same time. Approaches which shape landscape of projects in tourism: participation, compliancy with the region’s branding, multiple usability of interventions, trans disciplinary planning processes, service design and more. Architecture’s role in Architecture and tourism are very closely related activities. It can be said to depend on each other. Their mutual relationship is obvious since ancient times where the architecture, as a tourist attraction, had a very important role. This relationship is because there is architecture in tourism and at the same time tourism in architecture. Architecture and Tourism examines the reciprocal relationship between the modern practice of tourism and the built environment. It shows how photography, film and souvenirs have been deployed to help mediate and mythologize specific sites. It also explores how tourist itineraries, behavior and literature are institutionalized for popular consumption in order to support larger cultural objectives. That is a place to live, work, recreate, rest, relax and carry out tourism activities, usually designed by the architect. And tourism creates the avenue of escape to attractive destinations making architecture a touristic focus. Monuments have served as tourists’ attractions and have necessitated travels globally for recreational purposes. In recent times, contemporary architecture is seen to contribute immensely to the tourism sector and play a significant role in tourism development across the globe. In Nigeria, in spite of the numerous traditional architecture and monuments in existence, many are left unpreserved. Modern architecture is also not being seen as means of attraction for tourism purposes. Infrastructure, asaverred by Ayeni (2013), are the essential services and facilities needed for a society to function efficiently. Also serves as a potential determinant of the attractiveness of a tourism destination (Seetanah et al., 2011). This paper, therefore, review the role of architecture in tourism industry development in Nigeria.

ABSTRACT

This Study makes a case for the inclusion of container as an option for low income housing in Ijora Badia of Lagos State. Objectives of the research is to examine the effectiveness of housing policies, feasibility of  container for housing in Ijora, Badia; Users perception of container housing alternatives; proposals for prototypes of container housing modules to be adopted for use in Badia. The study adopted a field survey research design. Situational analysis of the site was carried out as well as an interview with stake holder companies, and representatives of the slum dwellers as well as various options explored various options on alternative material solutions were explored. Secondary data was collected from the Lagos State Government website, the research publications, amongst others. A design proposal was made with a nos. of 11ft sized containers to produce 9 nos. one bedroom apartments (low-rise) one a plot of land. The results revealed that container housing, although not yet well researched in Nigeria as alternative housing option, is quite resourceful if explored for housing provisions; it is modular, flexible and adaptable to whatever space constraints may exist on the site.  Failure by the government to adopt alternative housing materials in this present times will leave housing deficiency in Nigeria an enigma.

                                            ABSTRACT

The study assessment of the income generation by scavengers in Abuja Municipal area council was aimed at assessing the level of livelihood sustained by scavenging in the area. The methodology adopted was such that data were generated from questionnaires, interview, and observation methods. 120 copies of the questionnaires were administered to the respondents. The sample size was taken systematically from the four clusters of dumpsite in Karmo, Kuchingoro, Lugbe Federal Housing and Gosa according to the population encountered at each location at various points. Finally the results revealed that 33 percent of the respondents earned between N 4,000 and N14, 000 monthly, 17 percent earned between N15, 000 and N25, 000 monthly, 8 percent earned between N26, 000 and N36, 000 monthly, 3 percent of them earned N37, 000 and above monthly, while 39 percent of the respondents could not recall how much they earned monthly. Therefore, the study concludes that the reluctance of Abuja Environmental Protection Board and the government of Abuja Municipal Area Council to fashion out concrete ways of integrating and assisting the scavengers to carry out their roles effectively and efficiently are antithetical to sound waste management in AMAC. This is because, for scavengers to effectively participate in waste management and earn better income in AMAC, the government must give them encouragement. It is finally recommendation the government should subsidise the costs of Personal Protective Equipments (PPEs) and educate the scavengers on why they should protect themselves to avoid health and environmental hazards arising from dumpsites environment; and this will go a long way in helping scavengers save more money.

ABSTRACT

Soil samples collected in South Wales was extracted and asphaltenes were precipitated from the extract. The asphaltenes were then subjected to hydropyrolysis to determine the percentage yield of hydrocarbon from asphaltene matrix. Open column chromatography was performed on asphaltenehydropyrolysate gave a percentage recovery of 92 %, suggesting that this process is a veritable tool for the release of bound hydrocarbons in asphaltene matrix. The mass balance for hydrocarbon distribution is consistent with literature

ABSTRACT

Industrial clusters constitute an array of linked industries and other entities important to competition. Industrial clusters serve as an employment index reflecting the relative size and economic strengths of local industries. Characteristic to these clusters is the   uniqueness of their function, where the companies possess similar or complementary interests and the entire value chain exists within the cluster thus providing a holistic approach to employment and service delivery.  Poverty and environmental degradation continue to attract regular inter-disciplinary debate mainly due to the fact that they, on one hand, affect all aspects of human existence and on the other hand represent an inextricable connection between population explosion and uncontrolled urbanisation which remains a growing trend in Nigeria, making the poverty-environmental degradation nexus a challenge which every generation attempts to find solutions for their abatement. This paper examines the role of industrial clusters in the Nigerian built environment, highlighting the efforts of various governments in the take off of these cluster industries and the extent to which these cluster arrangements have abated poverty and environmental degradation.

ABSTRACT

Solid waste management continued to be the biggest threat to the sustainability of urban centers of developing countries. Most streets corners of these urban centers are characterized by heaps of uncollected wastes at drains, public spaces and road sides destroying the aesthetic qualities and environmental ecosystems of these cities, causing health risk to the populace. Thus, posing serious challenge to the municipalities who are in most cases responsible for the solid waste management in these cities. The typical or commonest method adapted by these agencies in dealing with the solid waste management   is the conventional   approach;   focusing   mainly   on   waste collection and disposal (transfer of waste from one destination to another). The resultant  consequences  being   huge   budget   spending   on   solid   waste management  but  little  collection, compelling  residents  to  resort to  various alternative disposals options that are harmful to the environment. This paper attempt to analyze the current waste management strategies in Bauchi metropolis, Nigeria. Observations, focus group discussion, oral interviews, content analysis and questionnaires formed the methodology of the research.

Keywords: conventional Waste Management, Solid Waste, Bauchi Metropolis.
