The usage of wastewater from swine farm for agriculture have study on the production of three plants such as shallot (Allium ascalonicum L.) marigold (Tagetes erecta L.) and ruzi grass (Bachiaria ruziziensis). The experiment was focusing on the growth production and metals accumulation (Pb Cu Fe Zn) in plant. The results shown that swine farm wastewater were a lot of organic substant and nutrient. The biological oxygen demand and chemical oxygen demand were out of standard. The heavy metals lead zinc copper and iron were amount 0.106 0.218 0.082 และ 0.866 mg/kg respectively. The productivity of shallot and ruzi grass were high growing that treated by swine farm wastewater. The marigold production (flower size dry weight and fresh weight) treated by swine farm wastewater found that were not significant from the marigold production that treated by control water. The amount of lead in shallot ruzi grass and marigold flower were out of standard. The shallot and ruzi root found the amount of zinc out of standard. The amount of copper and iron were not out of standard all three plant.

This study aims to survey the demand of the sub district administrative staffs in Phitsanulok province for self-development about administrative knowledge. The result showed that the essential knowledge for administration in the sub district administration organization requested via staffs was divided into 7 aspects. Knowledge development in financial accounting and taxation computer management profession education public health and environment was in the high level requirement whereas they have a medium level need for marketing knowledge improvement. Computer and the Internet were the highest requests. The follow was the knowledge about waste management. The effective and proper methods for knowledge development should be two day workshop in weekday (Monday to Friday) and the most available time was daytime (08:00–16:00). The speakers should be the government or public organization rather than private sector. The most proper total budgets (including food drink and documents) for workshop ranged from 500–1000 baht.

This paper presents the method to solve the transmission line parameters calculation problem with computer program. The transmission line parameters are an important of power system which calculates the voltage current power and other. Transmission line parameters program is programmed with Delphi in graphical user interface. This program can calculated the resistance inductance and capacitance of single and three phase transmission line. To verify the performance of the proposed program the results are compared with the manual method. The results show that the program method is able to obtained 100 percent accuracy

In this study the mao berry marc which was divided into 5 varieties including Fapratan Phusung Phupanthong Yaykhamta and mixed variety were dried in tray dryer at low temperature (50?C) and high temperature (60?C) for 72 hr. All samples were investigated their properties including yield color water activity pH tannin total phenolic total anthocyanin antioxidant activity in term of %DPPH activity total microorganism and yeast & mold content. It was found that the yield color in term of ?h aw tannin and anthocyanin content of low temperature drying sample showed the highest value. However the total microorganism and yeast & mold content of high temperature drying samples were not present in all samples which less than those recommended in the Thai Community Product Standard (dried fruits: 136/2003). Eight trained-panelists were used for Hedonic scale (1-9 point) sensory evaluation including clarity color odor taste and overall linking of high temperature drying samples were similar in five varieties (P>0.05).

The natural rubber with silica masterbatch was produced and used as based material in rubber compound modified from standard tread formulation given in ASTM E 1136. The reduction of mixing energy and rubber vulcanizate properties were investigated. Results indicate that in comparison with STR 5L compound the rubber with silica masterbatch i.e. fresh latex (FNRmSi) low viscosity natural rubber used 1.0 phr of hydrogen peroxide (LNR1mSi) and low viscosity natural rubber used 0.34 phr of hydrogen peroxide and 2.7 phr of potassium persulphate mixture (LNR2mSi) provides maximum mixing energy saving of 30.48% 33.37% and 37.20% respectively. The scorch time and cure time rise with increasing filler loading. The mechanical properties of LNR1mSi and LNR2mSi are similar to those STR5L compound whereas FNRmSi vulcanizate shows superior mechanical properties such as 300% modulus tear resistance abrasion resistance elongation at break and tensile strength. The homogenous distribution and interfacial interaction of silica filler and natural rubber matrix were enhanced by the self-assembled silica masterbatch as shown by the fracture surfaces morphology of the vulcanizate using a Scanning Electron Microscope (SEM). The silica masterbatch form has reduced the mixing power consumption and enhanced the mechanical properties.
