Abstract:
Optimization has become an imperative tool in treatment scheduling for cancer radiation therapy. It may be used to determine beam weights, beam directions, and appropriate use of beam modifiers such as wedges and blocks, with the aim of delivering a required dose to the tumor while sparing critical structures and normal tissue in close proximity. Linear programming formulations are a core computation in many approaches to treatment planning, because of the abundance of highly developed linear programming software. Furthermore the choice of formulation, algorithm, and pivot rule that perform paramount computations are sometimes not obvious, and the software’s default choices are sometimes pitiable. Here a number of linear programming formulations of treatment planning problem with dose volume constraints, conclusions are drawn about the formulations and variants.

Abstract:
The study investigated the effects of Component task analysis teaching strategy on secondary school students’ academic performance in Physics in Ekiti State, Nigeria for attaining sustainable goals in disoriented society. The research design adopted in the study was Pretest-Posttest Quasi- experimental. The sample for the study was 120 Senior Secondary One (SSI) Physics students, selected through the multistage sampling technique from a total population of 6,589 SS I students offering Physics in all the 184 public Senior Secondary Schools in Ekiti State. The instrument used to collect relevant data from the subjects was Physics Achievement Test (PAT). The reliability of the instrument was determined through the split-half method with the reliability coefficient of 0.86. Three null hypotheses were tested at 0.05 level of significance. The data collected were analysed using t-test and Analysis of Covariance (ANCOVA) statistical analysis. The results of the analyses showed that there was significant difference in the academic performance of students in Physics in the experimental and control groups in favour of experimental group. Based on the findings of the study, it was concluded that Component task analysis teaching strategy is more potent in boosting students’ performance in Physics in secondary schools than the conventional method in vogue in the nation and It was recommended that the conventional method presently in use by Physics teachers should either be improved upon, modified or replaced with an activity- based teaching approach (as appropriate).

Abstract:
in this paper we investigate the properties of fuzzy group and fuzzy sub groups and their types. also introduces the notion of a characteristic fuzzy sub group of fuzzy group. we define the algebraic structure of fuzzy sub group and some related properties are investigated. the purpose of this study is to implement the fuzzy set theory and group theory in fuzzy sub group

Abstract:
Let 𝐺 = (𝑉, 𝐸) be a graph. A u- 𝑣 a detour is a longest 𝑢- 𝑣 path. A subset D⊆V is called a detour set of G if every vertex in V-D lie in a detour joining the vertices of D. A subset D⊆V which is both a detour set and dominating set is called a detour dominating set of G and the cardinality of a minimum detour dominating set is called the detour domination number of G. In this paper, we introduce the concept of different detour domination numbers and find the same for some simple and special graphs

Abstract:
In this paper, we introduce commutative, archimedean, nonpotent Γ-semigroup, Putcha Γ-semigroup and 𝐸-𝑚 Γ-semigroup. We prove that a finitely generated, commutative, nonpotent, archimedian Γ-semigroup is power joined. We also prove that if 𝑆 is a commutative, nonpotent, archimedian Γ-semigroup, then, 𝑆 is power joined if and only if every finitely generalized sub-Γ-semigroup 𝐻 of 𝑆 is archimedian. Thereafer, we obtain some equivalent conditions. Then, we prove that an archimedian nonpotent Γ-semigroup is power joined if and only if the structure Γ-group 𝐺𝑠 = 𝑆/𝜌 of 𝑆 is periodic for some 𝑠 ∈ 𝑆; equivalently, it is true for all 𝑠 ∈ 𝑆. We also show that every medial Γ-semigroup 𝑆 is a left and right Putcha Γ-semigroup and that every 𝐸-𝑚 Γ-semigroup is a right and left Putcha Γ-semigroup.

Abstract:
Knowledge in Basic Science is central and indispensable to the development of every nation. The study investigated the effects of structured-inquiry teaching method on students’ academic performance in Basic science in Public Secondary Schools in Ekiti State, Nigeria. The research design adopted in the study was a Pretest-Posttest Quasi-experimental. The sample for the study comprised 140 Junior Secondary School two (JSS2) Basic Science students selected through the multistage sampling technique from a total population of 7,014 JSS2 Basic Science students in all the 184 Public Secondary Schools in Ekiti State. The instrument used to collect relevant data from the subjects was Basic Science Performance Test (BSPT). The reliability of the instrument was determined through the split-half method with the reliability coefficient of 0.91. Two null hypotheses were tested at 0.05 level of significance.The data collected were analyzed using t-test statistical analysis. The results of the analysis showed that there was a significant difference in the academic performance of students in Basic Science in the experimental and control groups in favour of the experimental group. Based on the findings of the study, it was concluded that structured-inquiry teaching method is more effective in improving students’ performance in Basic Science in Secondary Schools than the conventional method which is still widely in use and it was recommended that the conventional method presently in use by Basic Science teachers should either be improved on, modified or replaced with an activity-based teaching approach (as may be appropriate).

Abstract:
This paper looked into education as a tool for eradicating child trafficking in the 21st century. It present child trafficking as a concern in Nigeria presently and as a major violation of children’s right and an exploitative way of child labour. It also itemized some certain percentages of Nigerian in sex trade in some nations of the world. e.g Europe, Asia and some common routes by which they were taken, stopover locations with means of transportation were also discussed.The mode of operating child trafficking agencies were also unrevealed, which types of trafficking were highlighted to be internal and external with its causes and effects.Education being an acquisition of knowledge was seen particular ill of the society since education caters for the needs of the society and also forms the bedrock for any national development

Abstract:
Only when the input data is reliable can mathematical models and business intelligence systems for decision-making produce accurate and effective outputs. However, data taken from primary sources and gathered in a data mart may contain several anomalies that analysts must identify and correct. This research covers the activities involved in creating a high-quality dataset for business intelligence and data mining. Three techniques are addressed to achieve this goal: data validation, which detects and reduce anomalies and inconsistencies; data modification, which enhances the precision and robustness of learning algorithms; and data reduction, which produces a set of data with fewer characteristics and records but is just as insightful as the original dataset
