ABSTRACT

Field mapping of the Kaltungo inlier showed disposition of the rock units outcropped as stocks, plugs and intrusions were characteristic of a rocky outcrop. The litho logic units delineated in the study area consist of porphyritic biotite granite, biotite granite, medium grained granite, micro granite, pegmatite, diorite, protocataclasite, trachyte, trachy-andesite and basalt while the oldest sedimentary unit in the Upper Benue Trough, the Cretaceous Bima Sandstone Formation surrounds the inlier. Major strike-slip fault cross-cut the inlier from Labeke to Ture Pandi trending N60⁰E into the western block around Kufai, Billiri, Kalmai, Banganje, Tanglang and Tal and the eastern block around Kaltungo, Okra, Poshereng, Popandi, Lapan, Karel, Labeke Kulishin and Ture Pandi. The inlier is intensely sheared and faulted, trending dominantly NE-SW and NW-SE direction is in agreement with the general structural trend of the Nigerian Basement Complex.

ABSTRACT

 Land has been the major pivot of physical planning and development in Nigeria and virtually the entire world, and physical planners as the major promoters of development. Besides, numerous questions are being raised by the public regarding the status and credibility of physical planning. Thus, the aim of this paper is to examine the level of public awareness and perception on physical planning profession and practices and it’s implication on the effectiveness or otherwise.   For this purpose,  systematic random sampling was implored in sample choice and questionnaire administration to the selected samples, interviews  were conducted with some officials of planning authority. Relevant literatures were consulted also. The collated data was analysed. It reveals from the study that, most of the public are short of what town/physical planning is all about;  in terms of its rules, laws and activities which seems to hinder the effectiveness of the profession and its practice. To achieve effective planning practice in the study area, the study recommends the need for frequent public enlightenment Programmes on TV channels, Radio and print medias by Government, NGO’s and professional bodies of Planning. It also recommends the recruitment of more staff, organized public lectures, provision of more surveillance vehicles and adequate funding. Planning bodies should also advocate zero tolerance to corruption and planners should stick firmly to their code of conducts.

ABSTRACT

In this paper, effort has been made to geo-transform Google Earth imagery. The first order polynomial (Affine) method of geometric transformation was used to register imagery obtained from Google Earth using ArcMap 9.3 software. The real-world coordinates of Ground Control Points (GCPs) used in geo-transforming the image was obtained with Leica GX1230 GPS in static mode. The geometric accuracy of the initial transformed image was 0.04066m RMSE, and 0.00057m RMSE for the rectified image. To further test the accuracy of the image produced, a landed property from a geodetic GPS survey was overlaid on the imagery and a significant result was obtained. The analysis of the results obtained revealed low resolution of the imagery produced, which indicated that the geo-transformation of Google Earth imagery is not good enough for geodetic or large scale engineering purposes. However, it can be inferred that the geometric transformation of Google Earth imagery is an alternative tool for generating imagery for cadastral and small scale engineering surveys.

ABSTRACT

Waste materials, glass inclusive abound everywhere in the environment which has negative impacts on the environment. Also, the need for more and alternative building materials opens opportunities for sourcing of suitable materials. This paper investigates the suitability of Waste Glass Powder (WGP) as a cementing material to partially replace conventional Ordinary Portland Cement (OPC) in sandcrete block. To determine that, the particle size effect was evaluated using glass powder of sizes less than 100μm. A series of tests were conducted to determine the chemical composition of the WGP for cementitious characteristics and to study the effect of 10%, 20%, 30% and 40% replacement of OPC by WGP at mix proportion of 1:6 by weight. For the purpose of compressive strength test, 45 each of 225 x 225 x 450mm hollow sandcrete block and 100 x 100 x 100mm mortar cubes were produced and tested. The results show that the compressive strength of the blocks increases with increase in the percentage replacement. Blocks produced with 10% partial replacement have strengths which vary from 2.52N/mm² at 7 days curing to 3.42N/mm² at 28 days curing, while that of 20% partial replacement have strengths which vary from 2.84N/mm2 at 7 days curing to 3.46N/mm² at 28 days curing. The control blocks (at 0% of WGP) vary from 2.29N/mm² at 7 days curing to 3.29N/mm² at 28 days curing. It is thus observed that the 28 days curing compressive strength value of 3.46N/mm² at 20% replacement satisfies BS 2028 requirement. Thus, 20% is the optimum percentage replacement of OPC with WGP. It was also observed that blocks made with 10% replacement absorb less water than the control blocks. The implication of the results is that WGP is suitable for sandcrete blocks at 20% partial replacement and for water absorption property, up to 10% replacement is suitable.

ABSTRACT

Agricultural practises are known to be complementary as the waste of one tends to be the raw materials in the activities of the other. This is peculiar to crop production and animal husbandry as the dungs of animals are useful materials for enhancing the performance of soils for crop production. However, the tide seems to be turning in some part of Nigeria with the rise in conflict of interest of practitioners of the two agricultural endeavours. The activities of animal husbandry especially cattle rearing appears to be counterproductive on the production of crops as grazing animals feast on crop plantation. This negative act is injurious to man-environment nexus at the same time detrimental to food security and food supply. Conflict in any political entity has multifarious consequences on the physical, human, environmental and capital factors diminishing available opportunities for sustainable development.  In the light of many challenges faced by crop production farmers in rural communities in most Nigerian cities, this work examined environmental implications of conflicting agricultural practises while examining the need for mediation-negotiation as an essential arbiter in alternative dispute resolution whereby they share a common vision and demonstrate sufficient political will to manage the loggerhead between farmers and herdsmen in their domain and invariably boost food supply in the country.
