Chanyuth Tretipskul
The factors influencing of boar semen production were evaluated a total of 19,966 ejaculates from 517 PRRS free boars (2 purebred; 164D, 31P) and (2 crossbred; 268LY, 54PD). Semen parameters; volume (ml), sperm concentration (x106 sperm/ml) and total number of sperm per ejaculate (x109 sperm/ejaculate) were evaluated in relation to seasons as summer (Mar-Jun), rainy (Jul-Oct) and winter (Nov-Feb) and breed differences. Seasoning effected, the total number of sperm per ejaculate in winter was higher...

Genetic and functional analyses of a novel mutation in CRTAP gene in osteogenesis imperfecta

Natnicha Houngngam
Background Autosomal recessive type of osteogenesis imperfecta (OI) is caused by mutation in the gene encoding the intracellular collagen-modifying complex: cartilage-associated protein (CRTAP), prolyl 3-hydroxylase 1 (LEPRE1) and cyclophilin B (PPIB). The complex is responsible for one step in collagen post-translational modification, the prolyl 3-hydroxylation of specific proline residues at position 986 of type I collagen chains. Method We identified the mutation and its effect on the qualitative and quantitative defects in type I collagen...

Syngas production from co-gasification of coal and biomass

Supachita Krerkkaiwan
In this work, the co-pyrolysis and co-gasification of Indonesian coal (sub-bituminous) and two types of biomass (rice straw and Leucaena leucocepha) were studied using a drop-tube fixed bed reactor. The synergetic effect in co-processing was manifested by the higher gas yield and lower tar yield compared to the predicted values from the experiments which used either coal or biomass alone. Results showed that the synergetic effect was found especially at a biomass and coal ratio...

Myrcene and terpene regulation of TRPV1

C. Jansen, L.M.N Shimoda, J.K. Kawakami, L. Ang, A.J. Bacani, J.D. Baker, C. Badowski, M. Speck, A.J. Stokes, A.L. Small-Howard & H Turner
Nociceptive Transient Receptor Potential channels such as TRPV1 are targets for treating pain. Both antagonism and agonism of TRP channels can promote analgesia, through inactivation and chronic desensitization. Since plant-derived mixtures of cannabinoids and the Cannabis component myrcene have been suggested as pain therapeutics, we screened terpenes found in Cannabis for activity at TRPV1. We used inducible expression of TRPV1 to examine TRPV1-dependency of terpene-induced calcium flux responses. Terpenes contribute differentially to calcium fluxes via...

Resurgence of Chinese tea consumption as “High Culture” in contemporary Bangkok metropolis

Sakaorat Harnkarnchanasuwat
Chinese tea consumption is one of the outstanding Chinese cultures that has been handed down from ancient times to the present. In Thailand, Chinese tea consumption cannot be considered genuine Thai culture; however, it cannot be considered a passing trend that has come and gone either. With respect to Chinese tea, Bangkok has become a place known for having a variety of options for consumption of tea as “high culture” in the contemporary period. This...

Legibility of printed small-sized Thai characters under different illumination by means of cataract experiencing goggles

Boonchai Waleetorncheepsawat
Most of the outside information is collected to us through the visual system. Since the ratio of population of elderlies to young people in Thailand is increasing rapidly, the proper infrastructure of the visual environment suitable for elderlies is one of the urgent tasks of the country. The printed labels representing visual environment have been found to be expressed by so small letters and are too difficult for elderlies to read. A serious problem of...

Output feedback control of quad-rotor helicopter using linear parameter-varying method with saturation constraints

Apichart Serirojanakul
This thesis presents the output feedback control of the quad-rotor helicopter (quadrotor) with input saturation constraints. The main idea underlying controller design is the transformation of the nonlinear model to a linear parameter-varying (LPV) model of the quadrotor. Then, the LPV control technique is applied. To design the LPV controller, we first consider the linear quadratic regulator control of LPV systems. This results in the linear parameter-varying quadratic regulator (LPVQR) control. Next, when the input...
