This experimental research was to test a performance of flat-plate solar collectors using biodiesel as a working solution with a solar thermal system. The purposes were to promote a biodiesel use as an alternative fuel for higher efficient heat energy and as an added renewable energy for a production process and to provide a guideline in education and for development in the future. The experiment was to test a performance of flat sheet solar collectors using ASHRAE STANDARD 93-2003 and to test a thermal potential of 12 litres by volume of biodiesel in a 2 m2 flat- plate solar collector used as heat source of the system. Thus biodiesel was used as a working solution with a flow rate of 2.4 litre per minute and the test duration was between 09:00 am. and 03:00 pm. The result revealed the performance values of the flat-plate solar collector used in this experiment as FR( ) = 0.958 and FRUL = 15.02 W/m2K. The temperature of biodiesel in the solar thermal system increased from 33๐C to approximately 80-90๐C varied with solar radiation values. However; the mentioned degrees could be efficiently applied in biodiesel production process as a main heat source or a supplemental heat source depending on appropriate variables.

One of major missions of Rajamangala University of Technology Phra Nakorn is to promote studentscreation of research invention and innovation in order to add values to production sector and national academic service. The Promotion of Inventions and Innovations by Young Generation Project has been since 2008 initiated to provide necessary support development of undergraduate students works. The project aims to promote and improve students invention and innovation as well as to encourage national publication. This project has enhanced students professional expertise which would develop into Hands-on graduates. Results of the project were presented at national level and severaltools devices and products had been produced and evidently utilized to improve production process of communities and industrial sector. The 1st Rajamangala University of Technology Phra Nakhon Innovation and Technology Exhibition is another activity that has presented results of the project to public. The activities included an exhibition of students innovations ana technology a forum on Hands-on graduate development and a contest of students works. This initiation clearly corresponds with the mission to promote students creation of innovation in oder to produce hands-on graduates who have curiosity persistence technological expertise and morality in accordance with the university identity.

This research aims to transfer biogas digester construction technology and application of biogas in household to teachers and students of Suksasongkhro Tak school. They were instructed and trained about biogas digester construction and application of biogas produced from animal manure on household cooking in order to reduce LPG use. A total number of 330 teachers and students participated in the training. Results from 5-point scale questionnaire for project evaluation showed that the highest rank was location duration and food ( = 4.37 SD = 0.67). The second was knowledge utilization ( = 4.33 SD = 0.66). The third was trainers ( = 4.26 SD = 0.65) and the lowest was knowledge and understanding ( = 4.13 SD = 0.72). Regarding level of average post-training satisfaction the highest was 4.44 for knowledge and understanding while the lowest was 4.16 for question and answer. For success of the project it was found that every biogas digester done by participants could produce biogas used in place of LPG and could reduce monthly expense by about 1400 – 1500 baht. The total construction cost of biogas production system was 58000 baht with a payback period of 4 years. For students there were 3 science projects about biogas; including 1) comparison of biogas produced from food remains and animal manure; 2) comparison of biogas produced from pigs and cows manure; and 3) comparison of biogas produced from dry and fresh pigs manure.

This research was aimed to study the compressive strength and the abrasion resistance of Terrazzo floor which used glass cullet as aggregate. The mix proportion of Terrazzo was 1 : 2.5 (white cement : chipped stone) by weight. The weight percentages of replacement of chipped stone by glass cullet were 0 10 25 50 75 and 100% by weight of aggregate. The compressive strength and abrasion resistance of Terrazzo specimens were measured at 7 14 and 28 days. The results indicated that the compressive strength of mixtures with glass cullet of 0 10 25 50 75 and 100% were 581.11 540.81 534.83 480.94 435.42 and 343.71 kg/cm2 respectively. It showed that the compressive strength decreased with the increase of glass cullet content. The abrasion test of Terrazzo specimens showed that at low glass cullet content (10-50%) the abrasion resistance increased with the increase of glass cullet content. The mixtures with glass cullet of 75 and 100% have abrasion resistance nearly the same as the mixture without glass cullet

The research was conducted to study on effects of environmental management in evaporative cooling system (EVAP) house on productive performance of layer pullets. This study divided into 2 experiments. Experiment 1 was conducted to study on temperature and air velocity in evaporative cooling system (EVAP) house on productive performance of layer pullets. Four thousand and eight hundred layer pullets were raised on battery cage with 5 birds per cage and assigned in a Randomized Completely Block Design (RCBD) experiment with three treatments. Each treatment consisted of four blocks (four houses) and followed different temperature and air velocity in raising area of evaporative cooling system (EVAP) house as front area central area and back area. Results showed that temperature and air velocity in front area was grater body weight gain (BWG) average daily gain (ADG) and feed conversion ratio (FCR) of layer pullets than layer pullets were raised in back area of evaporative cooling system (EVAP) house (P<0.01) Experiment 2 was conducted to study on light color and number of H-Flame battery cage row in evaporative cooling system (EVAP) house on light intensity and productive performance of layer pullets. Nine thousand and six hundred layer pullets were raised on H-Flame battery cage with 5 birds per cage and assigned in a 2x4 factorial in Randomized Completely Block Design (RCBD) experiment with two factors. Factor A was light color comprised of range and blue). While Factor B was number of battery cage row comprised (first row second row third row and fourth row). Each treatment consisted of four blocks (four houses). Results showed that interaction between factor A and B on light intensity and uniformity of layer pullets with highly significantly different (P<0.01). However interaction between factor A and B and main effect (factor A and B) were investigated on body weight gain (BWG) average daily gain (ADG) and feed conversion ratio (FCR) (P>0.05). The data from this research was suggests the important for implicate to improve the egg production industry in further success.
