Abstract: This study was carried out to investigate the comparative assessment of domestic sewage discharge on water quality at Edjeba sewage treatment plant, Warri, Delta state. The pH, temperature, electrical conductivity, TDS, DO, TSS, turbidity, BOD, COD, oil and grease, salinity as chloride, sulphate, total nitrogen, hydrogen sulphide, iron, zinc, copper, chromium, Arsenic, mercury and total coliform test was carried out  on the untreated sewage, treated sewage and sample from the recipient environment. The physicochemical parameters of the untreated sewage, effluent and sample from the recipient environment were analysed using Standard Methods by American Public Health Association (APHA) and the results compared with the permissible limits of Federal Ministry of Environment (FMEnv). The result obtained indicated a pH of 6.42, temperature of 29.9°C, electrical conductivity of 624µs/cm, Dissolved Oxygen (DO) of 0.85mg/l, turbidity of 15NTU, Biochemical Oxygen Demand (BOD) of 20.50mg/l, Chemical Oxygen Demand (COD) of 22.45mg/l, iron (Fe) of 2.31mg/l and total coliform of 280mpn/100ml for untreated sewage. These values exceeded the effluent discharge limits of FMEnv. The physiochemical analysis results carried out on the effluent and sample from recipient environment showed that the values were all within permissible limits for discharge. The study therefore concluded that untreated sewage from Edjeba sewage treatment plant, if discharged to the recipient environment without prior treatment will cause pollution. Also, based on the results obtained, the effluent was safe for discharge without concerns for public health issues. It was recommended that proper maintenance of the existing central sewage treatment facility should be ensured for effective sewage treatment to avert potential public health risk.

Abstract: Rehabilitation centers for some people especially for those whom practice sports or suffering from injuries or disability is very essential to re participate in sport, or in the community to empower the people with an injury or disability and their families.
In all cases, the availability and validity of rehabilitation services is different in all stages and need special settings that vary between the nations and regions depends on different considerations such as the type of therapy it provides as a service, for example, medical rehabilitation and therapy needs to be provided in special care hospitals for special medical therapy.
This paper designed to highlight the comprehensive role of the rehabilitation services, which needs special Interior design that should be commonly available as possible in the region.
This paper will also argue the importance of using the research on the senior level as a base for the senior graduation project.

Abstract: Adsorption treatment of distillery effluent has great potential as a sustainable method as it is a low cost method. The aim of this investigation is to study the treatment method for purification of distillery spent wash by using Activated charcoal and Fly ash. For this, the study encompassing evaluation of reduction of various physical chemical parameters (color, odor, pH, COD, TS, TDS, Ca, Mg, Na and K) of distillery spent wash was checked by passing through the columns of Activated charcoal and Fly ash. The distillery effluent was acidic (pH 4.7) and dark brown in color which often cause psychological fear in farmers for utilization. Activated charcoal  treatment of spent wash exhibited good reduction in COD, TS, TDS, Mg, Na, Ca, after 72 hour treatment and increase in pH toward pH 7 followed by Fly ash. Treated spent wash induced a good growth of wheat seeds and this method can be used for purification of industrial spent wash at commercial level.

Abstract: The lungs play a very vital role in human respiratory system. It has five separate lobes which are detached by fissures of three types such as left and right oblique fissure and a horizontal fissure. The way of identifying the fissure lobes in computed tomography scanned lung images are difficult for the medical practitioners because of the incorrect shapes alongside with less contrast and the extraordinary noise associated with it [1]. The last phase of the lung cancer treatment is the elimination of the unhealthy lung by the major surgery. So, it is required to identify the location of the cancer affected part of the lungs by extracting the fissure lobes before making the proposal for the surgery. This paper presents a mechanized process of extracting the left oblique fissures and right oblique fissures by applying the Dual Tree Complex Wavelet Transform from the Computed Tomography lung images. This will help the medical practitioner to identify the lobar fissures from the computed tomography lung images.

Abstract: Two liquid crystalline compounds, namely of 2-sec-butyl-4-(4-methoxyphenyl) diazenyl) phenyl 4-(dodecyloxy) benzoate( I12a), and 2-sec-butyl-4-((4-nitrophenyl)diazenyl)phenyl 4-dodecyloxy)benzoate (I12b) were prepared. These compounds were characterized by elemental analysis, Infrared (IR), and Mass Spectroscopy. Their mesophase behavior was investigated by Differential Scanning Calorimetry (DSC). They were tested as antioxidants for Egyptian base oil. The oxidation was monitored using the change in the Total acid number (TAN) and viscosity. The data showed that of I12b is more efficiency than I12a.

Abstract: Shipyards works are traditionally hazardous, with an injury-accident rate more than twice that of construction and general industry. The losses of accidents could reach to death or financial losses. Losses can be reduced if proper corrective actions be taken after analyzing.
For this reason, this paper has been obtained to analyze these occupational accidents in Shipyard P in Egypt.
Duration of Study: Research data have been collected between 2012-2015 statistics of occupational accidents with Shipyard in Egypt, within this study, occupational accidents that occurred in the shipyard between those years are investigated for defining important data for every accident case
The statistical method has been followed during the study depends on collecting data of victim's and accident nature.
The study results Accident Frequency Rate (AFR) of 1.9, 2.6, 1.7, and 0.7 which show improved performance during the last two years due to applied additional control measures has been taken.
The lost time injury cases LTI present 50% of accidents cause of road and traffic accident and most of this accident due to using motorcycles as a transportation facility.
All fatalities happened due to a traffic accident on the road between the employees home and work place, and it was no fatality happened in the workplace
Workers in age group less than 20 years old had the highest number of days-away-from-work cases for all year. 48% of accident happened to illiterate workers, which has low knowledge and training. Workers in experiential group less than 5 years’ experience had the highest number of days-away-from-work cases for all study year.
The study showing lots of actions taking which decrease the accident frequency rate also the study recommends additional control measures for improving results according with international safety standard.

Abstract: Thin-layer drying of sweet potato (ipomoea batatas) using hot-air convectional dryer was studied in order to determine the effective moisture diffusivity, activation energy and the specific energy consumption. The effects of variables such as slice thickness, temperature and air speed on the drying of sweet potato was studied. Increase in air speed and temperature increased the drying rate. The effective moisture diffusivity obtained ranged from 3.52 x 10-10 to 6.76 x 10-10 m2/s for different air speed and temperature. The activation energy varied from 28.06 to 37.36 KJ/mol while the specific energy consumption ranged from 166.72 to 232.70 KWh/Kg. The data obtained in this study will be useful in designing industrial dryers.

Abstract: Economizer is an integral part of a boiler. It recovers some of the waste heat of hot flue gases going to chimney and thus helps in improving the boiler efficiency. The failure in the economizer tubes affects the performance of the boiler and hence its efficiency. The cause of failure may associated with water side corrosion, fire side corrosion over hearing , etc. Sulphuric acid dew point corrosion has been a quite common and important defect occurring in boilers running on fuel oils. The cause of sulphuric acid corrosion is found out and is rectified by giving suggestions. This project was carried out at BPCL Cochin refinery in order to find out the root cause of failure of utility boiler economizer tubes. Sulphuric acid corrosion was found to be the main reason for the failure of tubes. Remedial methods were recommended and the efficiency improvement using economizer was also calculated. The efficiency before and after failure are calculated.
