The objective of the current research is to identify the effective of the suggested instructional design that based on the teaching strategy for understanding in achievement for students(girls) of mathematics in the fifth grads secondary school. To achieve the research goal, the empirical research method is depended. In this method a realistic empirical design pre-test of two equivalent sets to determine the students’ grade is used. The following zero hypotheses is formulated “There is no statistical difference for the faction at 0.05 between the mean grad for the students of the empirical group who studied the subject using the Instructional design based on the teaching strategy for understanding and those who studied the same subject using traditional way in the grade testing”. The research society is determined with the studying secondary school for girls in public directorate Baghdad AL-Kurkh. 58 students in the fifth grade are selected randomly Then they are divided into two groups; empirical group are taught according to the the suggested instructional design that based on the teaching strategy for understanding and uniform group that are taught using the traditional way. The equivalence between the two groups is made using different variables (age, the previous grade for mathematic subject, intelligent and previous knowledge in mathematic test). To achieve the experiment's aims and collect its information, a multiple choices identification test of 40 objective paragraphs is formulated. After the test is presented to a set of experts and it is verified, it is applied o an exploratory sample to determine the test paragraph clarity, test instruction and test time, make an appropriate statistical analysis and validate the test verification and reliability. After that the test is be applied on the one research group. The results show that student that are taught it’s the instructional design is perform higher than the student who taught within the traditional way. The research conclude that teaching with the instruction design that based on the teaching strategy for understanding. Impact in improving the student grades of the empirical group than uniform group. Emphasis on under standing the subject and related the new topic with the previous one, lead to the cohesion of the scientific subject for them, that provide high ability of thinking and information using. For future work, we suggest make a similar sting for boys within the same grade to compare the results and also make a study using teaching strategy for understanding as a frame work on the graduated students in the mathematic department of educational colleges; by considering them as a teach in the future; analyze its impact on their students during their training in secondary school.
The presence of residual antibiotics in water results in the development of antibiotics resistant genes. The available wastewater treatment systems are not capable of removing such antibiotics from sewage. Thus, antibiotics need to be removed before the discharge of wastewater. Adsorption is among the promising techniques for the wastewater treatment to aid the removal of a wide range of organic and inorganic pollutants. The present work is a contribution to the search for an economical method for the removal of low concentrations of amoxicillin (AMX) from water by adsorption on water treatment residue, WTR, taken from a local drinking water facility. The chemical composition and the adsorptive characteristics of the material were first

Separation of Trigonelline, the major alkaloid in fenugreek seeds, is difficult because the extract of these seeds usually contains Trigonelline, choline, mucilage, and steroidal saponins, in addition to some other substances. This study amis to isolate the quaternary ammonium alkaloid (Trigonelline) and choline from fenugreek seeds (Trigonella-foenum graecum L.) which have similar physiochemical properties by modifying of the classical method. Seeds were defatted and then extracted with methanol. The presence of alkaloids was detected by using Mayer's and Dragendorff's reagents. In this work, trigonilline was isolated with traces of choline by subsequent processes of purification using analytical and preparative TLC techniques.

This article introduces the concept of finitely null-additive set function relative to the σ– ring and many properties of this concept have been discussed. Furthermore, to introduce and study the notion of finitely weakly null-additive set function relative to the σ– ring as a generalization of some concepts such as measure, countably additive, finitely additive, countably null-additive, countably weakly null-additive and finitely null-additive. As the first result, it has been proved that every finitely null-additive is a finitely weakly null-additive. Finally, the paper introduces a study of the concept of outer measure as a stronger form of finitely weakly null-additive.
