The potential of extracts of the Ficus hispida Linn to inhibit germination and growth of barnyardgrass (Echinochloa crus-galli) a common weed in rice. The bark leaves and fruit of F. hispida isolated by the Maceration and extracted by the polarity of the solvent (Sequential Extraction) with organic solvents such as hexane ethyl acetate and methanol when each part of the crude extract was tested the type of phytochemical tested for germinate inhibition root length inhibition stem length inhibition and dry weight inhibition of barnyardgrass and selected extracts with highest inhibition to separation using column chromatography the fractions tested repeating. The results showed that 1. Crude methanolic extracts from the bark leaves and fruit of barnyardgrass at a concentration of 3000 ppm showed highest inhibited percentage of germinate inhibition root length inhibition stem length inhibition and dry weight inhibition. 2. Fractions methanolic extracts from the bark leaves and fruit of barnyardgrass on a separate with column chromatography found that fractions extracts F5 F8 and F2 showed highest inhibited percentage of germinate inhibition root length inhibition stem length inhibition and dry weight inhibition.

The purpose of this research is to study the heavy metal removal from wastewater from laboratory by using adsorption process with firebricks. Waste water was collected among three courses of laboratory such as analytical chemistry principle chemistry and chemistry for engineers. The optimized absorption efficiencies of multi-elements with stirring time volume ratio and temperature were 2 hours 10 g/100 mL and room temperature respectively. It was found that absorption efficiencies of lead (Pb) copper (Cu) zinc (Zn) chromium (Cr) were 65.1 54.8 63.4% and ND respectively.

The purpose of this study was to Evaluation of Curriculum for the Bachelor of Science Program in Computer Technology of Rajamangala University of Technology Phra Nakhon. The CIPP Model was used as evaluated model. The samples in this research were 125 undergraduates 14 Instructors 17 graduates and 11 employers of graduates. The 4 questionnaires of rating scales was used as the research instrument. Percentage mean standard deviation were statistical method to analyze data. The results were as follows: 1. The samples agreed with the Context Evaluation in the aspect of curriculum objectives curriculum structure curriculum content were in moderate levels. 2. The samples agreed with the Input Evaluation in the aspect of Characteristics of undergraduates and Characteristics of instructors were in high levels supporting education was in moderate levels. 3.The samples agreed with the Process Evaluation in the aspect of curriculum Management. teaching Management experience training were in high levels . 4 . The sample’s satisfaction towards Input Evaluation in the aspect of professional knowledge and Professional Characteristics were in moderate levels Ethics was in high levels .

The Purposes of1bis Research were to study of Bachelor of Science Programs in Applied Chemistry and in related other areas in Thailand s Higher Educational Institutions. The sample consisted of 27 Programs of Bachelor ofScience Programs in chemistry Applied Chemistry and Industrial chemistry in Thailand s Higher Educational Institutions. Instruments used for collecting data were Curriculum Data Sheets. The data were analyzed by using SPSS for window. The statistics used were frequency percentage and mean. The results were as follows: 1. Most of the Bachelor of Science programs are chemistry. The others are Applied Chemistry and Industrial chemistry respectively. 2. The Total Course Credits of Bachelor of Science Programs were 137.12 Credits including General Education Courses (34.46 credits) Specific Courses (96.50 credits) and free elective courses (6.42 credits). 3. The Total Course Credits of the Bachelor of Science Programs before 2005 were 140.67 credits including General Education Courses (35.28 credits) specific courses (99.22 credits) and free elective courses (6.61 credits). 4. The Total Course Credits of the Bachelor of Science Programs s after 2005 were 129.13 credits including General education courses (32.63 credits) specific courses (90.38 credits) and free elective courses (8.76 credits). 5. The Total Course Credits of Bachelor of Science Programs in Applied Chemistry were . 130.67 credit including General education courses (37.67 credits) specific courses (85.00 credits) and free elective courses (8.00 credits). 6. The minors of Bachelor of Science programs in Applied Chemistry consisted of Industrial Chemistry and Management Environmental Chemistry Material Chemistry Natural Products Chemistry Polymer Chemistry Applied Chemistry for Industry Chemistry Education and Medicinal Biochemistry.

The purpose of this study was to investigate obtained knowledge using from Physics I for Engineers for daily life application of undergraduate student from faculty of engineering Rajamangala University of Technology Phra Nakorn. Sample was 316 students which taken from four engineering majors; computer electrical industrial and mechanical engineering. A questionnaire a four point scale was used as testing tool. The statistical analyses were performed in mean standard deviation and one way analysis of variance. The results revealed that students used their obtained knowledge in moderate level (3.10). Students in each programs showed significantly different used their obtained knowledge at 0.05 level. Electrical engineering students (3.27) showed highest number of the course content using follow by mechanical engineering (3.09) computer engineering (3.07) and industrial engineering (2.75) respectively.
