Spatial mathematical analysis : an application to mapping of dengue hemorrhagic fever in Thailand
Spatial mathematical analysis : an application to mapping of dengue hemorrhagic fever in Thailand

The objectives of this research are to estimate the morbidity rate of Dengue Hemorrhagic fever in each province of Thailand and to construct the map of the Dengue Hemorrhagic fever. A Bayesian model is used for the data analysis. The data are mathematical spatial correlated in the form of the conditional autoregressive model (CAR). The secondary data were collected at a provincial level. They were the number of Dengue Hemorrhagic fever patients rainfall and average temperature. The research found that the rainfall (RR = 1.0026) and the average temperature (RR = 1.2681) had influence on the morbidity of Dengue Hemorrhagic fever. The season during July to September had more influence on the morbidity of Dengue Hemorrhagic fever than during the other seasons. The top 5 highest morbidity rates per 100000 population were Chiangmai in October (1288.00) July (1096.00) September (804.30) Surin in October (772.30) and Nakhon Si Thammarat in August (666.20). The disease map constructed for showing the distribution of the disease is easy to understand and useful for public health.

Preparation of Thickener from Dry Dioscorea hispida powder for Textile Printing
Preparation of Thickener from Dry Dioscorea hispida powder for Textile Printing

The objective of this research was to study the feasibility for producing the dry Dioscorea hispida powder as a thickener. The product was investigated in their properties the compatibility with dye and chemicals in print paste color appearance by indicated with color hue value the time durability storage the residual substance after washing treatment and the color fastness in washing and rubbing methods. The results shown the dry Dioscorea hispida powder was used as thickener that it was the good characteristic like the famous textile printing thickener as alginate. The dry Dioscorea hispida powder thickener was 10%w/w had the equivalent viscosity as 8%w/w alginate. It had 3 days stability storage and good compatibility for direct dye reactive dye acid dye and disperse dye print pastes. The color appearances were corresponding with owned hue in color index databases. The thickener was completely in washing process. And the washing and rubbing fastness were good to excellent.

The Efficacy of Peroxyacetic Acid and Sodium Hypochlorite Solutions in Reducing Microorganisms on the Surface of Carved Fruits and Vegetables
The Efficacy of Peroxyacetic Acid and Sodium Hypochlorite Solutions in Reducing Microorganisms on the Surface of Carved Fruits and Vegetables

This study examined the efficacy of two sanitizers; peroxyacetic acid (PAA) and sodium hypochlorite (NaOCl) in reducing total microbial counts on the carved leaf-shape surface of five types of fruits and vegetables: pumpkin carrot radish cantaloupe and Japanese cucumber. The samples were dipped for 3 or 5 min in various concentrations of PAA (40 60 or 80 mg/L) and NaOCl (50 or 75 mg/L) with distilled water as the control. After dipping the samples were drained for 5 min and the total plate counts were determined in triplicate. Dipping in 60 mg/L of PAA for 3 min was the best treatment for reducing microorganisms on the surface of carved carrot and radish; and 80 mg/L of PAA for 5 min was the best treatment for reducing microorganisms on the surface of carved pumpkin cantaloupe and Japanese cucumber. PAA at concentration 60 -80 mg/L showed potential as an effective sanitizer for carved fruits and vegetables more so than both concentrations of NaOCl.
