The aim of this research is to study white and colour resist printing of dye extracted from dry nipa palm shell. The printing recipes and fixation condition were studied in this work. The result of white resist printing showed that 30 % owp of sodium carbonate (Na2CO3) was used to be a resisting agent. The steam fixation for 15 minutes was suitable to show a good white resist printing in whiteness and sharpness of printing pattern. The whiteness value was 35.05. The washing and rubbing fastness were good to very good and light fastness was fair. The tensile strengths of warp and weft directions were decreased to 10.29 % and 4.25 % respectively. The colour resist printing was using Curcuma longa Linn. powder as illuminant dye. The dye was miscible in 30 % owp of sodium carbonate. The colour resist printing results were corresponding as white resist printing results. The 15 minute of steam fixation showed a good colour resist printing. The Curcuma longa Linn dye could be fixed on silk fabric and showed a good colour strength and sharpness of pattern. The washing and rubbing fastness were good to very good. And light fastness was fair. The tensile strengths of warp and weft directions were decreased to 18.37 % and 4.18 % respectively.

This study was an aim to apply lacing technique to produce yarn accessories for value added and developing the new products. It was a survey research by questionnaires tool. The study was divided into 2 steps. The first was collected the basis data for product analyzed and appropriate design to produce the prototype products. Thai traditional design was chosen to master design prototype as kanok naree kacha and krabi traceries. All of these traceries are gentle and shown as the Thai design. Kanok is a thai traditional style that it was chosen for a represent design and combine together with product design and decoration trend on 2013-2014 in Formal & Sugary style. The prototype products 7 collections: necklace earring and brooch. The prototype products were accepted from the sample group which they were very good in the factors of the beautiful technique the utilization and the quality of products. The prototype had price in range 801 – 1 300 Bath. The prototypes were adequate detail. From these results the prototypes were response with customer and make an alternative choice to increase the household income.

Physical characteristics and acceptance of chocolate mousse  produced from commercial pasteurized milks contained different fat content
Physical characteristics and acceptance of chocolate mousse produced from commercial pasteurized milks contained different fat content

Chemical composition of commercial pasteurized milks contained different fat content (full-fat; FF low-fat; LF and non-fat; NF) was studied. NF contained the lowest fat content (0.12%) with the highest protein content (3.20%). NF exhibited the highest foaming ability and stability. The chemical compositions physical and sensorial properties of chocolate mousse produced from FF LF or NF were also investigated. M-NF had the lowest in fat content resulting in energy reduction when compared with M-FF and M-LF. M-NF also showed the highest firmness and adhesiveness (p<0.05). This was probably due to different chemical composition of pasteurized milk used. For color measurement M-FF showed the highest L* value. However all chocolate mousse samples had no difference likeness score for texture taste and flavor (p>0.05). From the results commercial pasteurized non-fat milk could be not only used for chocolate mousse production without effect on textural and sensorial properties but the energy from fat was also reduced.

The chemical structures of bioactive compounds of ficus hispida linn
The chemical structures of bioactive compounds of ficus hispida linn

Study the chemical structure of the bioactive compound extracted from the leaves of the Ficus hispida Linn with extraction techniques Sequential Extraction using three organic solvents hexane ethyl acetate and methanol . Phytochemical examination testing antimicrobial activity of crude extracts and fraction of methanol extracts with the four species of microorganisms Vibrio cholerae Staphylococcus aureus ATCC 25923 Streptococcus mutans ATCC 27175 Vibrio paraheamolyticus and to determine the molecular structure of compounds. The results showed that 1. Crude methanol extract of the leaves of the Ficus hispida Linn show inhibitory microbial species more than crude extracts of hexane and ethyl acetate . 2. Testing antimicrobial activity of methanol extracts fraction was found to inhibit microbial highest F5 show. 3. The molecular structure of compounds crystals are colorless mp. 188-195 0C. Research should further study the molecular structure and biological activity of bioactive compounds in other areas including anti-cancer Antimalarial and antioxidant activity of different parts of the study. The roots leaf flower and fruit seeds to plant information for the selection and to further develop research in the next commercial.

Forecasting model for the export quantity of concentrated latex
Forecasting model for the export quantity of concentrated latex

The objective of this research is to construct the appropriate forecasting model for the export quantity of concentrated latex by the three time series analysis methods which are Box-Jenkins method Winters’ multiplicative exponential smoothing method and combined forecasting method. Time series data from the website of Office of Agricultural Economics during January 1998 to February 2014 (194 values) are used and divided into two series. The first 182 values from January 1998 until February 2013 for the models prediction and the last 12 values from March 2013 until February 2014 for comparison the performance of forecasting models via the criterion of the lowest root mean squared error and the criterion of the highest correlation coefficient between existing values and forecasted values. Research findings indicated that for all forecasting methods that have been studied the most powerful method is the combined forecasting and the forecasting model is where and represent the single forecasts at time t from Box-Jenkins method and Winters’ multiplicative exponential smoothing method respectively.
