This article examines the influence of positive job feeling on job satisfaction among workers in Lagos State Ministries. A priori expectation is that positive job feeling has a correlation with job satisfaction among workers in Lagos State Ministries. The study sampled six ministries where a sample of four employee categories (Top Management staff, Senior Managers, Middle Lower Managers, and non-managerial employees) was made. A structured questionnaire containing 8 items drawn from the variables (dependent and independent variables) was the main instrument used to explicate data from respondents, measuring the various aspects that reflect the nature of these variables. Besides the primary source, secondary sources such as books, journals and internet materials were also used to conduct the research. The study adopted analytical models such as correlation, regression and path analyses in assessing the research question, while the chi-square was used to analyse the hypothesis. In conclusion, the article found that positive correlation exists between positive job feelings and job satisfaction among workers in Lagos state ministries, and recommended that factors of perceived fairness should be strengthened as it promotes positive job feelings which in turn motivate job satisfaction.

This paper presents a deep study on the application of Data mining Techniques in the field of Agriculture. Data mining software applications using various methodologies have been developed by both commercial and research centers. Using this software applications Agricultural eco system is also managed. Eco system management includes soil management. Recent technologies are nowadays able to provide a lot of information on agricultural-related activities, which can then be analyzed in order to find important information .Efficient techniques can be developed and tailored for solving complex soil datasets using data mining.

Research has found that active student engagement in classroom activities can enhance academic achievement, promote retention and application of knowledge. This study investigated the relationship between students’ engagement and facilitation in a student-centred learning environment. The study was conducted at the University of Uyo, Akwa Ibom State, Nigeria. 307 Vocational Education students formed the population, from where 174 were drawn to form the sample. The results of the study indicated that facilitation is positively related to students’ engagement. It was concluded that facilitative learning environment is positively related to student engagement as quality instruction mediates students’ engagement.

The nutrient and anti- nutrient compositions of the raw and cooked species of Cucurbita maxima fruit consumed in the eastern part of Nigeria were determined. The proximate compositions of the fruit samples showed that the fruit was high in moisture (87.1±0.38%) but low in protein (1.87±0.1%), fat (0.8±0.62%) and carbohydrate (3.96±0.17%). The low fat and protein contents appear to be a common feature of the fruits of the Cucurbitacae family. The fruit of C. maxima sample was found to be poor in the mineral elements. However, it had higher values of magnesium, calcium and phosphorus but very low values of potassium and sodium. The compositions of the mineral elements were also reduced after boiling. The fruit sample had low values of vitamins A (42.39±1.05 mg/100g), E (14.25±0.18 mg/100g) and C (25.67±1.27 mg/100g). Vitamins A and E were not significantly affected by boiling. The fruit sample was found to be rich in some phytochemicals with established medicinal values as well as some anti-nutrients (tannins, HCN and oxalates). However, boiling which is a normal food preparation technique was found to be able to reduce these anti-nutrients to safe levels.

Today, multi-stage compressors serve in many industry branches. The multi-stage compressor design is primarily focused on storage or process conditions. Outside of the guaranteed time that the compressor manufacturer ensures, material fatigue and other mechanical problems that occur during process cause off-design operation of compressors. In this study, the relative Mach number in the discharge and inducer, including the non-dimensional mass flow rate are studied and compared with appropriate available theory.
