This research applies Project Evaluation and Review Technique (PERT) model to estimate acceptable duration for execution of each activity having random variable of time and some probability distribution for sand dredging operation in Niger Delta. The study takes into account proper planning, scheduling, controlling and allotment of dredging activities time using a project network model PERT. The model evaluated how acceptable time and saving cost could be achieved in a scenario of activities having random time variables. Readily available data of activities time from 2014 – 2017 were used to analyze the time estimate for various activities at a selected dredge site Aleto-Eleme in Port Harcourt metropolis Rivers State-Nigeria. The PERT was applied for the data analysis, to construct the PERT scheme for the dredging operations. Finally, parametric control for project evaluation and review techniques of acceptable time for the dredging activities were determined.

Aim: The aim of the study was to determine the frequency of occurrence and percentage distribution of Kell blood group antigens in indigenes of Ogoni ethnic group of Rivers State, Nigeria. Study Design:  This was a cross-sectional study carried out among indigenes of Ogoni whose first generational parental origin is Ogoni. A total of 101 subjects (49 females and 52 males), within the age of 30–60 years were recruited for the study and they were apparently healthy and free from transfusion transmissible infections upon serological screening. Place and Duration of Study: Ogoniland is located in an area along the Niger Delta Eastern edge, and to the north-east of the Imo River and Port Harcourt city. Ogoniland covers about 1036 Sq Km and borders the Bay of Guinea. All participants were recruited in Bori. Bori is the traditional headquarter of Ogoni. Bori is located on latitude: 4040ʹ34.64ʺ N and longitude: 7021ʹ54.68ʺ E. The analysis was carried out at the Post Graduate Laboratory of Rivers State University, Nkpolu-Oroworukwo, Port Harcourt, Rivers State, Nigeria. Port Harcourt, the capital of Rivers State, is located on latitude 4.750N and longitude 7.000E and lies along Bonny River in the Niger Delta. All subjects were recruited the same day and their blood samples collected on 2nd October, 2019, and analysis conducted on 3rd October, 2019. Methodology: Identification of Kell blood group antigens was done using Anti-Kell monoclonal reagent, prepared by Lorne Laboratories Ltd, UK. Lot No: 76090-A5; Expiry Date: 2021/02/21. Phenotyping of red cells was done using tube method as described by Lorne Laboratory Ltd. Results: The result showed zero frequency of occurrence and percentage distribution of Kell blood group antigen in the studied population (49 males and 52 females). Conclusion: The presence of Kell blood group antigens in indigenes of Ogoni recruited for the study which serve as representative of the Ogonis was rare. It is therefore necessary to take into cognizance that haemolytic transfusion reactions due to Kell antigens and antibodies will rarely occur, and as such Kell blood group is not significant in blood transfusion and in antenatal and blood group serology amongst the Ogonis.

The status of a neglected, common tropical protozoan parasitic flagellate, Trichomonas vaginalis, causing vulvovaginal trichomonias is (VVT) was re-evaluated among female subjects in Port Harcourt, Rivers State, Nigeria. The study area consisted University of Port Harcourt Teaching Hospital (UPTH), Braithwaite Memorial Specialist Hospital (BMSH) and Rivers State University of Science and Technology (RSUST), all in Port Harcourt, Niger Delta Region. Informed consent was sought and obtained before sample collection. Standard parasitological techniques were employed in vaginal swab and urine analysis. Two hundred and forty female subjects, aged 11-60 years were examined in 2014, out of which 22.5% were infected whereas in the precious study in 2006, the prevalence was 10% out of 500 subjects. UPTH had more VVT rates(9.7%, 30%) than BMSH (8%, 18.8%), in both studies respectively, although the infection is not location dependent (P>0.05). Age group 11-20 years (46.7%) had the highest infection rate inlatter with age group 51-60 years(5%) as the least; age group 19-29 years had (16.5%) as the highest in the former. Occupational prevalence shows that undergraduates and students were more infected with VVT (40%) and (25%) than others in latter while traders were most infected (11.1%) in the former, although VVT was not significantly (p>0.05) occupation related. Non-pregnant subjects (26.6%) were more infected than pregnant ones (14%);statistical analysis showed that pregnancy has close association with VVT butit is not pregnancy dependent (p>0.05). The unmarried (30%) had higher prevalence than married (11.7%). The results showed that Trichomonas vaginalis can tolerate wide range of acidic pH (4-5.5). The prevalence of VVT is on the increase; there is need for more awareness campaign and action plan for the control and elimination of this neglected common tropical disease of the youth.KEYWORD: Vulvovaginal trichomoniasis, women, Niger Delta Region, re-evaluation, upsurge.

The water quality and periphyton parameters were investigated at 5 designated stations along Ntawogba stream system that lies within the Port Harcourt metropolis located between latitude 4º5” N and 5º 00”N and longitude 6º55” E and 7º 00”E. Sampling was done for dry (January – March 2004) and wet (June – August 2004)seasons using standard procedures. Samples were collected at the designated stations along the water course for physicochemical (temperature, pH, conductivity, alkalinity DO, BOD5, NO3, NH3, PO4, SO4) and periphyton descriptors (species richness, species diversity, abundance, biomass, and productivity). The spatio-temporal differences for the parameters were evaluated and the physicochemical attributes demonstrated spatial and seasonal trends but were essentially not statistically significant while the periphyton descriptors demonstrated seasonal and spatial differences and are more reliably affected by the waste water discharges.

Wastewater samples were collected from an oil industry at the point of discharge for a period of two years, from January 2018 – December 2019. The wastewater samples were analyzed for different physicochemical parameters such as temperature, turbidity, total dissolved solids (TDS), total suspended solids (TSS), conductivity, pH, alkalinity, salinity, total hydrocarbon content (THC), biochemical oxygen demand (BOD) and chemical oxygen demand (COD) to examine their conformity to fulfill requirements as recommended by World Health Organization (WHO), Federal Ministry of Environment (FME) and Drinking Water Association (DWA). The results indicated that all the parameters in the discharged wastewater were within acceptable limits of the regulatory bodies. The field data showed that the investigated firm conformed to the law by carrying out proper procedures before discharging the effluents into the public drain and river. Therefore, the release of wastewater from the industry doesn't constitute a danger to the environment as well as aquatic organisms.
