Removal of free fatty acid from used palm oil by coffee husk ash / Vanida Chairgulprasert, Porntip Madlah
" ABSTRAK
Reduction of free fatty acid (FFA) in used palm oil was determined after treatment of waste cooking oil with an adsorbent derived from coffee bean husk ash. Coffee husks were burned at 600 ºC for 12 hrs to obtain the adsorbent ash. Free fatty acid removal efficiency was optimized with respect to ash dosage, contact time and temperature. It was found that shaking ash (1 g) with waste palm oil (50 g) at 250 rpm ... "

Adsorption of ammonia and total phosphorus in surface water using zeolite and activated carbon: case study of Chuat Man Canal, Samut Prakan / Anyarin Pithapakdeesatith, Natha Hungspreug, Bundit Anurugsa
" ABSTRAK
Ammonia and phosphorus have been recognized as the cause of eutrophication in surface water. Chuat Man Canal is faced with water quality degradation problem due to the high concentrations of ammonia and total phosphorus in the water body that makes it unsuitable for fish ponds. Removal of ammonia and phosphorus by the adsorption process is simple and not requires chemical use. In addition, ammonia is well adsorbed by activated carbon and zeolite while phosphorus is ... "

Stability of MHD unsteady nanofluid flow through expanding or contracting channel with porous walls / M. K. Rahman, Md. S. Alam, M A. H. Khan.
" ABSTRACT
The objective of the present study is to investigate the influence of external magnetic field on unsteady incompressible flow of water based nanofluid through a successively expanding or contracting channel with porous walls. the basic governing equations with boundary conditions are non-dimensionalized using appropriate transformation to ordinary differential equations, which are then solved using power series with the help of Hermite-Padè approximation method. the instability of the flow is shown using bifurcation graph and the ...

Erector spinae muscle activity during lifted people with two persons in lifting phase of manual human handling (MHH)
" ABSTRACT
The objective of this study was to determine the activity of erector spinae muscle in four techniques of lifting phase of manual human handling; two-handed seat carry, four-handed seat carry, fore-and-aft carry and chair carry. Thirty-two (16 couples) healthy young men lifted subjects weighing 60±5 kg from table heights of 50 cm and 100 cm. Surface electromyography was used to evaluate lumbar erector spinae activity during lifting. The four-handed seat carry technique ... "

Development of a Simple Inclined Algal Culture System for Outdoor Cultivation / Supenya Chittapun, Theppanya Charoenrat, Ingkamonphat Maijui, Sompot Antimanon
" ABSTRACT
To overcome the disadvantages of open pond and cement tube as an outdoor algal cultured system, a simple inclined algal culture system was developed. the system composed of an 18.9 L polyethylene terephthalate (PET)bottle placed on a degree adjustable stand using an air pump to generate water mixing and circulation. The system was tested by culturing 45 mL Oscillatoria sp. in 13 L Blue-Green-11 (BG-11)medium supplemented with 3 g L-1 NaNO3 in plastic bottle, which ... "

Screening and preliminary optimizations for dihydroxyacetone production from glycerol by the gluconobacter and asaia isolates Found in Thailand / Issara Poljungreed, Siwarutt Boonyarattanakalin, Pattaraporn Yukphan
" ABSTRAK
This study aims to investigate the feasibility of using a minimal glycerol medium with inorganic salt supplementation for a low-cost dihydroxyacetone (DHA) production by bacteria. Acetic acid bacterial isolates of Gluconobacter and Asaia, which are found in the Northern, North-Eastern, Middle, Western, and Southern regions of Thailand, were evaluated for their ability to produce DHA using glycerol as a carbon source. During the qualitative screening, 66 isolates, including Gluconobacter (61 isolates) and Asaia (5 isolates), ... "

Effect of organic loading and nitrogen concentration on the efficiency of the sequencing batch reactor (SBR) system with electroplating wastewater (EPWW) / Suntud Sirianuntapiboon, Kanidta Chairattanawan
" ABSTRAK
The study was concerned with the effects of the organic loading as food/microbe (F/M) and nitrogen concentration as BOD5: TN on the sequencing batch reactor (SBR) system efficiency and performance with 1:5 diluted-electroplating wastewater (EPWW) solutions. The results showed that chemical oxygen demand (COD) and biological oxygen demand (BOD5) removal efficiencies were almost the same with the organic loadings of 0.125-0.375 kg BOD5/m3.d. The CN- and Zn2+ loadings of 1.2-2.9 and 1.6-4.0 g/m3.d did ... "
