In model building, forecasting is the ultimate goal since it assists in policy implementation and further research work. This paper aimed at establishing a robust quantile regression analysis.  Appropriate model and parameters of the model with their statistical test for effective prediction was established. It has been established that quantile regression relative to ordinary least squares produce regression estimates that are more robust against outliers.From 5th to 99th percentile, results showed that, at 25th percentile the number of tillers and plant height are more significant with p-value of 0.044 and 0.001 at 0.05 level of significance compare to others. The generalized linear models considered showed insignificance with p-value 1.000 and 0.760 at 0.05 level of significance.However, quantile regression tells us what happened as we move from the smallest to the highest quantile in estimating the goodness of fit test for the model for proper forecasting also, the model has been establishedat 25th percentiles.(Yield = -2419.596 + 1.352(Tillers) + 45.322(Height)) with the best yield which is significant and the best amongst others.

Since covid 19 was declared a world pandemic, its effects on various sectors is steadily being looked at. This paper sought to look into the effects of covid 19 on education within Kisumu county in Kenya. Using a desk top review of secondary data methodology and observation as well, the paper looked at the effects of covid 19 on learners, parents and teachers where it was established that the pandemic largely affected the quality of education in Kisumu county negatively. Even though some minimal positive effects were noted but still with challenges which called for improvement in future. The paper has proposed a number of recommendations and drawn conclusion on preparedness and mitigation for similar situations in future.

Englerina drummondii Balle ex Polhill & Wiens commonly known as mistletoe is widely known and use for the treatment of various illments by the traditionalists in Africa. The aim of this study is to evaluate the effect of hydroalcohol extract of Englerina drummondii Balle ex Polhill & Wiens on biochemical parameters such as superoxide dismutase (SOD), malon dialdehyde (MDA), catalase, cholesterol and total protein following administration of mono sodium glutamate in female wistar rats. The results revealed that Superoxide dismutase (SOD) is significally increased in groups 5 and 9 when compared with control. control group and when the MSG 800mg/kg only group is compared with group 8, shows a significance decreased in SOD and when compared with group 9, it shows a significance increased in SOD. Catalase (CAT) shows a significance decreased in groups 2, 4, 5, 8, and 9 when compared with control group and shows significance increased in group 7 and when the MSG 800mg/kg only group is compared with groups 1, 6, and 7, it shows a significance increased in CAT and groups 4, 8, and 9 shows a significance decreased in CAT. Malon dialdehyde: When normal control group is compared with groups 2, 3, 4, 6, 7, 8, and 9 shows a significance increased in MDA and group 5 shows a significance decreased in MDA. Also, when MSG 800mg only group is compared with groups 1, 3, 4, 5, 6, 7, 8, and 9 shows a significance decreased in MDA.

Total protein: When normal control group is compared with group 9 there is a significance increased in total protein and when MSG 800mg only group is compared with group 7 there is a decreased in total protein. Total cholesterol: When normal control group is compared with groups 4, 5, 7, and 9 shows a significance increased in total cholesterol and when MSG 800mg only group is compared with group 4 shows a significance increased in total cholesterol.

Coagulation-flocculation process was used to treat paint effluent stream with Telfairia occidentalis seed powder (FPSC) as coagulant. The crude effluent was characterized by a high level of BOD5 with initial concentration of 2205 mg/l. Proximate analysis of the coagulant revealed that the Percentage moisture content was 9.06 %, ash content 6.81%, fat content 35.28 %, crude protein 25.47 %, crude fiber 9.33 % and carbohydrate content 14.05 %. Fourier Transform Infrared Spectroscopy (FTIR) showed that the coagulant contained –NH2, -OH, and -C-H, which are some functional groups that enhance coagulation process. Jar test experiments employed for the coagulation-flocculation process involved 4 min of rapid mixing at 100 rpm and 20 min of slow mixing at 40 rpm. A central composite design (CCD), which is a standard design of response surface methodology (RSM) was used to evaluate the effects and interactions of three major factors (coagulant dosage, coagulation pH, and settling time) on the biochemical oxygen demand (BOD5) removal efficiency. The results indicate that at the optimum conditions of 4.0 g/l for the coagulant dosage, 4.0 for pH, and 40 min settling time, the maximum BOD5 removal efficiency achieved was 80.29 %. The quadratic model developed for the response variable successfully describes the experimental data (R2 = 96.83 %).

Corporate image is seen as the mental picture of an organization and the totality of these mental pictures comprises of what is referred to corporate. The study examines the relationship between corporate image and customer perception of primary health care centres in Port Harcourt, Nigeria. A total of one hundred and thirty six (136) questionnaires were distributed to the respondents of the primary health care centres. One hundred and eleven (111) representing 81.6% were retrieved and useful for the study. Multiple regression was used to analyse the data. The analysis showed a positive and strong significant relationship between corporate identity, corporate reputation, corporate communication and customer perception. The study reveals that corporate identity significantly relates with customer perception positively, corporate reputation at the other hand insignificantly relates with customer perception and there is a negative relationship between corporate communication and customer perception. The study concludes that there is a positive and strong relationship between corporate identity and customer perception, while corporate reputation, corporate communication insignificantly relates with customer perception. The study further recommends that firms of primary health care centres should display a positive corporate image that gives customers a positive first impression about the firm.
