This research studied the factors that affect the efficiency of phosphate reduction in the wastewater of the washing process with CaCO3 and CaO produced from eggshell and mussel shell. The study found that the optimum condition for adsorption when using CaCO3 from eggshell is to adjust the pH to be equal to 10 take 15 minutes to absorb and add 1 gram of sorbent which can reduce the phosphate content by 25 percent and when changing the adsorbent to CaO the optimum condition for phosphate removal is to adjust the pH to 7 take 15 minutes to absorb and add 1 gram of adsorbent which can reduce the phosphate content by 24 percent. The optimum conditions for adsorption when using CaCO3 from mussel shell were to adjust the pH to 10 take 45 minutes to absorb and add 1 gram of sorbent which can reduce the phosphate content by 25 percent and when changing adsorbents to CaO the optimum condition for phosphate removal is to adjust the pH to 10 take 15 minutes to absorb and add 3 grams of adsorbents which can reduce the phosphate content by 24 percent. In addition when studying the adsorption of impurities in the wastewater such as conductivity turbidity COD and BOD it is found that the optimum reduction conditions can reduce the impurities of the parameters that mentioned above were 19.32 2.60 54.77 and 16.67 percent respectively. CaCO3 and CaO produced from eggshell and mussel shell can be used to absorb impurities in wastewater before releasing into natural water sources.

In this work solar erythemal ultraviolet radiation (EUV) which affects human skin and skin cancer was investigated at Songkhla province (7.2°N 100.6°E). EUV was converted to UV index then the data was used for model development and forecasting of hourly UV index using Artificial Neural Network (ANN). The ANN model has one input layer two hidden layers and one output layer. This input layer consists of extraterrestrial erythemal ultraviolet radiation solar zenith angle aerosol optical depth and cloud index which affect ultraviolet radiation and the output layer is hourly UV index. The results show that hourly UV index obtained from ANN and that from the measurement are in reasonable agreement with root mean square difference of 12.8% and mean bias difference of -2.4%. For forecasting of the hourly UV index the data for 7 days earlier was used for forecasting the next UV index for one day or nine-hour (08:00 am.-16:00 pm.). Multi-layer perceptron and back propagation algorithm were used in the model forecasting. The results show that the UV index from the model forecasting is reasonable agrees with UV index from measurement with root mean square difference of 17.0% and mean bias difference of 0.3%.

Rice flour-based cookies are gluten-free products. Cricket powder and isolated soy protein are alternative protein sources which can provide desirable nutrition. Xanthan gum is one of the hydrocolloids affecting the texture of cookies. This study investigated the effect of cricket powder (CP) isolated soy protein (ISP) and xanthan gum on the physical chemical and sensory qualities of rice flour-based cookies. The substitution of rice flour with two protein sources CP (25 and 35%) and ISP (0 25 and 35%) in the cookie formulations which were evaluated for their qualities using a 2x3 factorial arrangement in a completely randomized design. The result showed that when CP increased or ISP decreased the diameter of the product significantly (p≤0.05) increased but the hardness of the product significantly (p≤0.05) decreased. The effect of xanthan gum (0 0.14 0.28 and 0.42%) on the quality of products was also evaluated. It indicated that the increase in xanthan gum content significantly (p≤0.05) increased water activity moisture content and hardness of product while the liking score for hardness and overall liking significantly (p≤0.05) decreased. Therefore the optimal formula of rice flour cookies was 25% CP and 35% ISP for rice flour replacement without xanthan gum.

In spite of the copyright law in Thailand where distributing or obtaining a copyrighted work without the permission of the copyright holder is against the law illegal streaming and downloading of music is dramatically increasing. This changing behaviour of consumers has an incredible impact on the music industry as a whole. Our paper analyses the influence of intellectual property infringement on Thailand’s music industry income. The research tools employed in this study are a questionnaire and an in-depth interview to enable analysis. We found that after the evolution of musical technology in the 1990s internet-based music consumption has become significantly more popular and increasingly consumers are streaming sharing and discovering digital music all across the globe including in Thailand. With this new development of digital music the dynamics of the music industry have been affected significantly both in terms of income and number of entrepreneurs. Multiple regression analysis results show that the amount of unauthorized downloading of copyrighted music has a negative effect on Thailand’s music industry income. In contrast the number of property disputes from illegal downloading of copyrighted music has a positive effect on this industry income. The results suggest that entrepreneurs should pay attention to warranty information on products and prices and security of financial transactions in order to encourage consumer authorized online purchasing. In addition law enforcement can help achieve the goal of decreasing online music piracy.
