Fillers play vital role on the engineering properties of the bituminous paving mixes. Cement, lime and stone dust are used as conventionally as fillers. In this study, effort has been made to determine the effects of different fillers (non-conventional and conventional) on the Marshall properties of bituminous paving mixes. For this purpose, non-conventional filler such as waste ceramic tiles powder, Wood Ash and pop-cement and conventional filler such as quarry dust were used. These materials were tested in accordance to the standard test procedure of AASHTO. Total 40 of test specimens were prepared by using the selected materials in different proportions in asphaltic mixes as substitute fillers as replacement to that of a conventional filler on HMA, with Quarry Dust serving as the control. The preliminary test was carried out with the production of 24 sample, 6 Runs per sample, Marshal stability and flow test, bulk density etc. were performed on the HMA mixtures giving the result for the optimum bitumen content OBC, determining the feasibility of the selected fillers in comparison to that of the control, from which the Final design mix involved the production of 16 test specimen, 4 runs per sample for WCT, POP-C, WA,QD. The required test was performed on the asphaltic mixes such as, XRF, marshal stability and flow, ITS test, material testing. Etc. revealing the effects of the selected substitute fillers on HMA in comparison control. Roads are among the vital assets of any nation. Apart from carrying people, vehicles, and goods, roads also provide avenues for such service apparatuses as water, electricity, sewerages, etc. thereby serving as a veritable tool for socio-economic development. A close look at the Nigerian road network reveals the enormous infrastructural systems problems. These problems, in the main, are more maintenance-related. Since the provision of roads is cost-intensive, one would have expected appropriate maintenance to safeguard them from total deterioration, which ultimately leads to eventual rehabilitation or reconstruction with its cost implications. Roads, like any other development assets, function maximally over the whole period of their economic life when regular maintenance is applied. This paper, therefore, examined the road maintenance situation in Nigeria and concluded that road maintenance culture in the country is in a good state, but with the use of sustainable methods the performance can be improved. Therefore, proffers proactive road maintenance strategies for sustainable socio-economic development should be adopted. The use of waste recycled material in road construction nowadays is considered a positive means of providing improved pavement performance. This thesis was focused on evaluating the effects of various materials, waste materials inclusive, which can be used as replacement for substitute fillers on hot mix asphalt concrete.

SYSTEM INTEGRATION FOR SMART PAPERLESS SHIP
PROF DR OLADOKUN SULAIMAN OLANREWAJU
Sea Transportation provides a safe and reliable source for moving people and cargo across the ocean. The government and private sector provide these services, while the Government moves personnel and cargo to support global peacekeeping activities while the civilian sea transportation activities focus on providing leisure cruises and the shipment of consumer goods. These safe and efficient services are obtained through the cooperative efforts of the government and civilian sea carriers, and seaports throughout the world required connectivity raging from within ship system integration and ship sore operation, which has been much facilitated by evolution of computer age. The use of the use of new information technology and interfacing all the associated service areas of maritime industry- sea and shore has lead to reducing papers and hence cutting of threes and beneficial environmental benefit of excess water absorption and greater capture of carbon dioxide. Human race has achieved much civilization and development in recent years until it seem as development is closed to the peak. However, new philosophy under are being promoted in recent years include proactive behaviors, recycling, system integration and conservation to make all what has been built meaningful and efficient. This paper discuss how system integration under smart ship concept within ship and shore.

Overuse of chemicals like triclosan has been suggested to cause sensitive bacteria to evolve resistance to its antibacterial actions. Locally medicated Soaps play an important role in the prevention and treatment of infections because they have the ability to remove and kill pathogens and this ability is well exploited in skin hygiene. The antibacterial activities of locally produced black soap were examined against some clinical isolates of pathogenic microorganism (Staphylococcus aureus) using Kirby-Bauer modified disk diffusion method. Result revealed that the pattern of inhibition varied (P<0.05) with the soap concentration and the organism tested. The zone of inhibition ranged from 16.70mm to 30.00mm with sample A1 having the highest zone of inhibition. The soap was more effective on Staphylococcus aureus with maximum zone of growth inhibition of 30mm at 100%w/v. The minimum inhibition concentration and minimum bactericidal concentration was 6.25 and 12.5%w/v for sample A and B respectively. The ingredients used in the preparation the soap may be responsible for the antibacterial potentials of this medicated soap.

Sclerocarya birrea were used for an array of human ailments in Nigeria and other African countries as an important medicinal plant. 200 g of Sclerocarya birrea stem barks were extracted using five different solvents sequentially in order of increasing polarity. The chemical constituents of the extracts from the stem bark of Sclerocarya birrea were separated by thin layer chromatography (TLC). The extracts were fractionated by silica gel column and the fractions were collected at regular intervals. Two fractions were collected from the ethyl acetate extract and one from the acetone extract. The ethyl acetate fraction was subjected to structural analysis using Infrared (IR) and Gas Chromatography-Mass Spectrometry (GC-MS) Spectroscopic techniques. The results from IR absorption frequencies showed the presence of OH, benzene ring and t-butyl group and 2, 4-bis (1, 1-dimethyl ethyl) phenol with molecular ion peak at M/Z = 206 and base peak at M/Z = 191 was identified using GC-MS spectroscopy.

The model summary gives us the usefulness of the model and provides the -2 log likelihood and pseudo R2 values for the full model. The Cox & Snell R Square and Nagelkerke R Square values shows the amount of variation in the dependent variable explained by the model (explanatory variables) from 0 – 1. In the table above 5.5% of the variation in the dependent variable is explained by the logistic model. Nagelkerke R Square is 10% relationship between the predictors and prediction. -2log likelihood is 641.414 which is high and indicates a poor prediction of the outcome because the smaller the statistic the better the model. -2LL value for this model (641.414) is what was compared to -2LL for the previous null model in the omnibus test of model coefficient which told us that there was significant decrease in -2LL, that is, our new model (with explanatory variables) is significantly better fit than the null model.

The major threat of Road Transport is the increasing number of accidents on a daily basis. According to the survey report most of the road accidents are caused by negligence of rules and regulations by the people who drive the vehicles. This work presents intelligent Driver’s Speed Control Management based on Radio Frequency Identification (RFID). It employed RFID tags integrated with Toy Vehicles and RFID Readers, mounted on road network while ATMEGA 328 synchronised the communication between them. In order to check the Vehicle Speed Limit Violator, the system needs to detect the movement of the vehicle and record the time along the road. To achieve this, we used a Transceiver to send information to a PC with Database and Graphic User Interface (GUI) that were developed by MYSQL and Visual Basic (VB) Software Application respectively. Whenever vehicle over speeds, sensor triggers the embedded module and sends information through Transceiver to the PC. The Bio-Data and Particulars especially Plate Numbers of the Drivers’ /Cars’ owners are to be pre-loaded and stored in the database during Registration of the Vehicles and Processing of the License. Five (5) Toy Cars with mechanical inbuilt engine were made use of as prototype. The result obtained was quite satisfactory and if prototype can be adopted, drivers can be monitored remotely and caught when disobeys the traffic rule.
