A development of python script for analysis and design reinforced concrete beam
A development of python script for analysis and design reinforced concrete beam

This research studies the development of Python Script which is the open source code used for the analysis design and draws the detailing of reinforced concrete beam elements. The SGV script was used for detailing the output of beam section. The results of the research shown the development of Python Script can be used for the analysis design and draw the reinforced concrete bean sections. The output of shear force diagram and bending moment diagram can be applied for design beam sections by the strength design method and draw the detailing of beam sections

Potential of extracts of Ficus hispida  linn for controlling germination and Growth of Weed in Rice Field for Increase the value of biodiversity and its sustainable use
Potential of extracts of Ficus hispida linn for controlling germination and Growth of Weed in Rice Field for Increase the value of biodiversity and its sustainable use

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.

Technical specification and Agreement for the map system of RMUTK

The development and update a map in Rajamangala University of Technology Krungthep in geographic information system with the measurement map system in a large scale map by use theoretical surveying all basic such as ground surveying aerial photogrammetry remote sensing theory Processing and the accuracy validation survey. These are part of a map system. Methodology or procedures all a map system will out technical specification and agreement to implementation a map system for the definition purposes. This Technical specification and agreement are under the standards of the organization and institution in a field survey. Those standards or rules taken improve the application to modify the Technical specification and agreement of Rajamangala University of Technology Krungthep only. The results of the study can be divided into main data 9 groups and 30 groups of data from geography at Rajamangala University of Technology Krungthep and standards or rules of organization institution together with the criteria processing and the criteria acceptance tolerances of the measure survey. The results of testing the system map by this the frame of technical specification and agreement. The engineering student survey of Rajamangala University of Technology Krungthep study technical specification and agreement and provides map system. By study used south bangkok area. Student group has set up a system to map the technical specification and agreement created. Plan defined

Preparation of titanium dioxide supported on activated carbon
Preparation of titanium dioxide supported on activated carbon

The purpose of this research work was to synthesize titanium dioxide supported on activated carbon and used it as a catalyst for dye decolorisation. The effect of preparing factors on titanium dioxide supported on activated carbon such as calcinations temperature and the amount of carbon supports were investigated at 300 400 and 500OC and in range of 5-30 percent by weight respectively. The X-ray diffraction (XRD) technique was used to detect the crystal structure of prepared catalysts. It was found that all peaks were anatase phase. The morphology of these catalysts was analyzed by scanning electron microscope (SEM) and transmission electron microscope (TEM) techniques. The results showed regularly distribution of titanium dioxide supported on activated carbon. The particle size of obtained catalysts was 5-10 nm. The Brunauer-Emmett-Teller (BET) technique was analyzed physical characteristic of catalysts. The specific surface area average pore diameter and pore volume of catalysts was 151.02-784.13 m2/g 26.94-64.35 and 0.24-0.55 cm3/g respectively. Furthermore the activity of obtained catalyst was carried out by using these catalysts to decolourise dye aqueous solution. The titanium dioxide supported on activated carbon 20 percent by weight can obtain 99.78% decolourisation at dye concentration 75 mg/L catalyst concentration 0.5 g/L within 90 minute. Comparison with titanium dioxide P25 (commercial grade) titanium dioxide supported on activated carbon has higher ability. This is because it was not only photocatalytic reaction but it was also absorption

Enhancement quality of rice seed by using  bio-extract fermented from pig placenta and by using wood vinegar
Enhancement quality of rice seed by using bio-extract fermented from pig placenta and by using wood vinegar

This study was undertaken to determine effect of bio-extract fermented from pig placenta and effect of wood vinegar solutions on seed germination percentage and speed of germination of 2 rice cultivars Chai Nat 1 and Sang Yod Phattalung. The experiment was conducted in factorial in completely randomized design with 2 factors and 4 replications. The first factor was ratios of the solutions to water and the second was duration for seed incubation. The results demonstrated that wood vinegar showed more positive effect on rice seed germination performances than that of bio-extract. Speed of germination was affected by an inter-action between the dilutions of the solutions and the duration for seed incubation. In Chai nat 1 experiment the seed soaked in 20 times dilution of bio-extract and subsequently incubated for 24 hrs increased speed of germination of the seed. While soaking the seed in 400 times dilution of wood vinegar and incubated for 24 hrs could enhance both percentage and speed of the seed germination. In Sang Yod Phattalung experiment soaking the seed in 50 times dilution of bio-extract and subsequently incubated for 48 hrs or soaking the seed in 300 times dilution of wood vinegar and incubated for 48 hrs could enhance both percentage and speed of seed germination. According to the results we concluded that soaking rice seed in bio-extract of pig placenta fermentation or in wood vinegar solutions could enhance the seed quality.
