Modular refinery projects were born out of a bid by the Federal Government of Nigeria to achieve the three-pronged aim of discouraging illegal oil refining, eliminating environmental degradation and boosting local refining of petroleum products. Investors were granted licenses to establish (LTE) modular refineries (MR) of varying operational capacities. The MR policy has been considered timely and necessary, because Nigeria imports almost all of the refined petroleum consumed locally. However, several years after the take-off of the MR policy, none of the licensed MRs has been completed. Some of the licenses have been withdrawn due to stagnation and lack of visible progress on the part of the investors. This paper aimed to assess the factors hindering the progress and completion of MR projects in Nigeria. Secondary data obtained from the Department of Petroleum Resources (DPR) was used to examine the licensing regime, operational characteristics and progress achieved for licensed MRs. The data was further analyzed and examined using frequency count and percentage analysis which revealed that 59.09% of licensed MRs have funding as the major challenge impeding their completion. This barrier might perhaps be best tackled by linking up MR investors with venture capitalists, rather than through direct funding by government. In extreme cases, government might provide some form of guarantees.

In this work a composite briquette formed from agricultural waste (rice and wheat husks) with the manual hydraulic press which was fabricated for this kind of purpose. The briquettes was prepared and characterized as an effort for alternative fuel to the rural and urban households in Nigeria. The samples of rice and wheat husks were grinded and sieved with a sieve mesh. Thereafter the samples were properly mixed with a binder made from gum Arabic and obtained seven different ratios of rice and wheat husks RH:WH ( 100:0, 90:10, 80:20, 70:30, 60:40, 50:50, 0:100). The ash content, moisture content, bulk density, volatile matter, fixed carbon and calorific values were determined. The experimental results show that the ash content ranged from 8.60 % to 12.01 %, moisture content ranged from 28.01 % to 42.97 %, bulk density ranged from 0.30 g/cm3 to 0.33 g/cm3, respectively after briquetting, FTIR spectra of the composite briquettes revealed the participation and presence of –NH2, -NH, -CO, -COO, -OH, -CH3, SO2. The results obtained for the calculated calorific values of the composite briquette revealed that the calculated values compared well with those of the American Standard of Testing Materials (ASTM) and is also in accordance with the reported values in the acceptable range of 17 MJ/kg to 21 MJ/kg. It was discovered that the briquette at 60:40 and 90:10 of rice and wheat husks have the highest calorific values and implies that they have more heating advantage and are therefore recommended as an alternative fuel to contend with the conventional fuel (charcoal and firewood).

The activities of humans affects the environment through different ways creating negative impact to the natural environments and this need to be minimize greatly to make sure that there is a clean air, food and water for everybody on the earth. The aim of this research work therefore is to assess the impact of sawdust on ambient air quality at Dei-Dei International Market Abuja, Nigeria. The data collected from the field were subjected to statistical analysis To identify sawdust generation and disposal techniques in Dei-Dei market. Questions relating to sawdust generation, quantity and disposal techniques were asked and responses were subjected to descriptive statistics in order to determine the quantity of sawdust generated and the most commonly used disposal techniques in the study area. The result it indicated that 7% of the respondents said less than 10kg of saw waste is being generated daily in their stand; 17% of the respondents said 20-50kg were generated; 26% of the respondents said 60-80kg were generated while higher percentage of the respondents 48% said above 100kg of waste are being generated daily. Implication of Sawdust shows that, 3.3% sawmill workers and 4.2% inhabitants of the Environment signified that they had knowledge and experiences of the impact of sawmill operation on health. While a greater proportion of 42.5% sawmill workers and 50% inhabitants of the Environment said that they never had knowledge and experience of the impact of sawmill operation on health. It is concluded that Most operations carried out in the mills were largely supported by manual handling which often result to overexertion and a long term health hazards. Personal protection devices such as earmuff or plug, hand gloves were not used adequately and were often considered as irrelevant and disturbing. It is recommended that Measures such as the identification of hazards that are associated with wood dust and other substances in wood based industries should guide the workers in planning for processing activities in order to eliminate hazards.

Most of the rural roads in Nigeria are in deplorable condition making movement within and outside rural settlement difficult. The road conditions thus affect marketing of agricultural commodities in the available periodic markets but the extent of the effects is not clearly understood in the states. The paper examines rural road characteristics and effects on periodic marketing of agricultural commodities in Kogi West Senatorial District, Kogi State. The specific objectives are examine the spatio – temporal pattern of rural road development over space and time, identify the types and periodicity of markets in the study area, examine are the nature/ types of road connecting periodic markets and identify the challenges of rural road transport to periodic market. The study adopted multistage sampling technique to selected 279 traders, 88 motor drivers/transporters for the survey. Descriptive statistics such as frequencies, tables, percentages, bar and pie charts were used where appropriate. The results revealed that 34% of roads were rehabilitated from 1999 -2017, 66% were still in a bad and deplorable state. The Beta accessibility index for the sampled LGAs is less than 1.50 meaning that the beta index for the LGAs is not significant enough to promote reasonable and a significant rural market patronage in the study areas. Nearest neighbor index for the studied LGAs are approximately 1.10 and the composite Nearest Neighbour index calculated (Rn of 0.60) shows that periodic markets are randomly distributed in the study area. This means that the pattern was not as a result of any deliberate planning. The binary matrix for the LGAs revealed that the periodic markets of Iyara, Iyamoye, Ayegunle and Ayetoro (Ijumu) Ofere and Ayede Opa (Kabba/Bunu) Mopa,Takete Idde and Ayede Amuro (Mopa/Amuro) Ponyan, Ejuku, Jege, Takete shu and Isanlu Mokutu (Y/East) Oke – Ere, Iyamerin, Gbaruku and Ejiba (Yagba West) were better connected and more accessible to traders. The study revealed that the agricultural commodities marketed in the study area are grains (Maize, Sorghum), Tuber crops (Yam, Cassava and Cocoyam) and Cash crops (Cocoa, Coffee, Rubber and Kolanuts). The result of Multiple Regression Analysis shows that the cost of transport to markets contributed 8.7%, distance covered to markets and time taken to markets contributed 6%, the nature of road to market contribute 1.9% and periodicity of markets have negative parameter estimate with the marketing of agricultural commodities. It is concluded that the characteristics of rural roads, cost of transport, distance covered as well as time taken to markets affect the periodic marketing of agricultural commodities in Kogi West Senatorial District. Recommendations made include Local Government Authority should make effort to maintain the existing rural roads for better improvement at all seasons of the year. Better connectivity and accessibility of the periodic markets can probably improve patronage of rural periodic markets and marketing of agricultural commodities in Kogi West Senatorial District.

Aeromagnetic data and 2D electrical resistivity geophysical methods have been integrated to investigate structurally controlled mineralization in areas between Bosso LGA and Katcha LGA, Niger State, Nigeria. The area is bound within Latitudes 9.22°N to 9.26°N and Longitudes 6.20°E to 6.24°E of Bida Sheet 185. The area is underlain by rocks belonging to the Nigerian Basement Complex comprising of Gneiss, Schist, granite and sandstones. Shuttle Radar Topography Mission Digital Elevation Model (SRTM DEM) was processed to extract surface topographic lineaments of the area, while Aeromagnetic data was processed to extract magnetic lineaments of the area. These were combined to form a composite lineament map of the area. Rosette plots of these lineament orientations were plotted. Further processing of the aeromagnetic data yielded the Source Parameter Imaging (SPI) map which was used to delineate areas that are sufficiently shallow for economic mineral occurrence. Integration of all these results formed the basis from which the profiles for the 2D electrical resistivity survey were extracted. Surface topographic lineaments trend NNE – SSW while that of the magnetic lineaments are orthogonal to it, trending in the WSW – SSE direction. This is typical for the area under study.2D pseudo-sections reveal presence of conductive bodies that may likely be disseminated metal ores within the depth of about15 m to 20 m. High resistive materials could be seen at the bottom of some pseudo-sections. This may be attributed to fresh rock that underlies those profiles. Areas with relatively high resistivity values represent silicification and presence of quartz veins. These are usually targets for economic mineralization. It is therefore recommended that anomalous areas are followed up with geochemical surveys and positive results be followed up with coring at designated points to determine the quality of gold, other associated metals and trace elements within the host rock.

The study adopted mixed research method that is (qualitative and quantitative research approach). The research strategy is the used of literature, direct observation through the use checklist as well as questionnaire as instrument for data collection. Data were obtained using random sampling technique. The total of seventy eight (76) questionnaires were administered to professionals to obtained information on the suitable and mostly used safety gadgets for construction operations on a likert scale 1-5 (1= strongly agree, 2=agree, 3=moderately agree, 4=disagree, 5=strongly disagree) as well as direct observation through the use of check list were also used to access the level of compliance to the use of safety gadgets on construction sites. Content analysis, Ranking and Relative Important Index (RII) were employed as method for data analysis. The findings showed the safety gadgets specified by law, the suitable and the mostly used safety gadgets for construction operations in the study area and the level of compliance to the use of safety gadgets. The outcome of the study showed that four (4) components have high level of compliance, five (5) components have medium level of compliance, three (3) components have low level of compliance and seven (7) components have non-compliance to the use of safety gadgets in the study area. The reasons for non-compliance are lack of adequate provision of safety gadgets, low monitoring system, lack of awareness, communication, ignorance and negligence, carelessness and religious believes and lack of strict enforcement of safety rules and regulations by constituted authorities. The study concluded that effective use of audio and visual displaying gadgets on sites, safety training for the workers and ensure one safety manager is employ on every construction site, there should be proper monitoring by constituted authorities to ensure full compliance by construction companies. This will go a long way in improving safety on construction sites.

The paper examines how population control could be a tool for national development. In the federal government of Nigeria, under the military presidency of Gen. Ibrahim BadamosiBabangida, introduced a National Population Policy/target for the country. The main focus of the policy was on how to control population growth rate of the country. When one examines the present population situation of Nigeria, the National population target expectations, it is clear that not much has been achieved. The simple but not obvious reason in that the policy formulators failed to appreciate the fact that it is difficult to change people’s mind set, traditional and belief system. Changing this internalized habit and belief system requires a thorough education by professional. This paper maintained that population control if properly handled will serve as a transformational tool for National Development.

The study entitled “Planning for sustainable Water Supply in Barama” was aimed at assessing existing water supply situation in Barama with a view of making planning proposa Population for the study is gotten from estimated population. The estimated population represents population for the study. And this is obtained from the number of households and average number of persons per household. This implied that, estimated population equals to average number of persons per household multiplied by number of households. This is expressed as follows: Estimated population = Average number of persons per household x Number of households. For this study, average number of persons per household is taken to be seven (5), number of households counted in the area was 200. With this, the estimated population is 5 x 200 = 1000 people. Systematic sampling technique was adopted where 200 compounds in Barama were considered as the target population. Ten (10%) per cent comprising of 500 of the 200 houses covering 100 people were taken as the sample. Structured Questionnaire consisting of 14 number questions were administered at interval of every five compound to cover the 200 houses. The study revealed that 70% of the residents used untreated water for domestic purposes. The researcher recommended that state government should intervene and rehabilitate water treatment plant at Gada Vimtim and extend it to serve Barama.

Solid waste management (SWM) is public health service whose importance is often understated. COVID-19 pandemic is proving to be an unprecedented disaster for human health, social contacts, and the economy worldwide. It is evident that, the COVID-19 may spread through municipal solid waste (MSW), if collected, bagged, handled, transported, or disposed off inappropriately. Under the stress placed by the current pandemic on the sanitary performance across all MSW management (MSWM) chains, this industry needs to re-examine its infrastructure resilience with respect to all processes, from waste identification, classification, collection, separation, storage, transportation, recycling, treatment and disposal. The study examined the Municipal Solid Waste Management system in Kano Metropolis under COVID-19 Pandemic: Challenges. The paper provides an overview of the severe challenges placed by COVID-19 onto MSW systems, highlighting the essential role of waste management (WM) in public health protection during the ongoing pandemic. It also discusses the measures issued by various international organisations and countries for protection of MSWM employees (MSWEs), identifying gaps, especially for developing countries, where personal protection equipment (PPE) and clear guidelines to MSWEs may not have been provided, and the general public may not be well informed. The need to protect MSWEs health has affected the municipal solid waste management industry in the study area. The results of the findings clearly show that major streets, several open spaces and even water ways were turn out to be the refuse dump sites. The study also reveals that most of the refuse dumps are left unattended to during the COVID-19 lockdown. The study further shows that COVID-19 pandemic become one of the major caused for the continuous growth of these refuse heaps at the shoulders of the major streets, open spaces and water bodies which lead to spread of infectious diseases. Therefore, the paper concludes with recommendations for the strong legislation protection of MSWM industry operating under public health crisis conditions.

Water has been identified as the most precious resource available to mankind and to sustain it, proper drastic measures have to be put in place. The research tends to shows the potentials in rainwater harvesting using the college of environmental studies as a case study using GIS and remote sensing approach. To achieve the aim, data regarding the total number of students, academic staff and non- academic staff were collected from each department within the college, major catchment surfaces were identified within the study area (rooftop, bare ground, gravel ground and vegetation), high resolution satellite image of the study was downloaded (SASplanet) and loaded into Arc GIS software. Supervised classification was carried out and the area covered by each surface/class was calculated (Vegetation 4988.3115, Gravel 8913.118112, Rooftop 9418.418, Bare ground 51332.0559). Using 20litre standard for water usage/day for developing country, 18,020litres and 216240litres will be required per day and per annum respectively. The analysis shows that the amount of water that can be harvested is 19,397,592.598litres (L) in the study area which shows that it is almost 90times enough for the college and even if 50litres/per/day is considered, it shows that harvested water was 3times enough for the college. It was recommended that the school management should plan ahead of using the system of rainwater harvesting system as an alternative source of water in case of any eventual scarcity of water for their daily activities and should also practice a system of roofing for rainwater collection going forward.

Radiation shielding properties of concrete samples with different cement and aggregate sizes ranging from 5mm to 20mm were investigated using Co-60 gamma radiation source at CERT ABU zaria. The result revealed the calculated mean free path (MPF) with a range values of (0.033 to 0.070) m for samples DG and BU respectively. Similarly, mass attenuation coefficient and half value layer (HVL) have range values of (1.9 to 2.75) x10-3m2/kg and (0.023 to 0.049) m for the samples respectively. This shows that samples DG1, DG2 and DG3 have better shielding properties due to its lower mass attenuation coefficient MFP and HVL. This research shows that samples DG have a very good shielding ability compare to different types of concrete and glasses

One of the basic amenities expected of a progressive society is good road network. Unfortunately, this road network for the most part has resulted to large number of deaths as a result of road accidents, not so much for high speed of the drivers as it has been for bad sections of the road popularly known as potholes that come about as a result of wear and tear of the surface tar. Statistics abound and grows by the day to the fact that potholes is arguably a large contributor to the total number of road accidents. Previous researches have focused on responsive solutions instead of preventive. In this work, A GPS app on an android phone was used to capture the coordinates of the potholes on a chosen route using goggle map. First, a drive-through on the chosen route was done from origin to destination while coordinates were taken as documented in the data collection section. Then an in-house prototype android application software was developed using MIT APP Inventor to carry out the experiment, taking into cognizance the pothole coordinates. Another drive-through was carried out with the software installed on an android phone to locate any potholes on the choosen route. The result of the experiment showed an accuracy of about 97.3% in pothole notification. Our proposed system is capable of reducing the present high rate of road accidents due to potholes to its barest minimum.
