หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Stove Used in Dry Storage)

ผู้เขียน:ImgLarb Rubsiri

สื่อสิ่งพิมพ์:pdf

Abstract

This research has been conducted to cooperate with the dry storage that has been presened previously. Electrical heaters were used in the previous research (Dry Storage) which is unsuitable for rural areas and rather expensive. The main purpose of this research is aimed at adaptation of wastes from industries and agricultural products to be used as fuels in appropriate stoves. Four types of stoves were disigned and two of them selected for this research. The 4 stoves give almost the same result. The second and the third types are rather complicate in construction and costly; heat loss is also high. Stove no. 1 and 2 have been selected for this research. The test results show that liverated heat from these two stoves is much greater than required. In some tests the steel grids even melted.

Abstract

The study of the different stages of sugar cane juice collected from 9 sugar cane factories in the middle and the eastern part of Thailand, on the general properties such as temperature, pH, sugar content and total acid content; and especially emphasized on the number and species of bacteria which showed an important role in decomposing the sugar content in the juices revealed that the Streptococcus sp. was the major population and showed the highest activity in decomposing the sucrose content in the juice. Lactobacillus fermentum, Leuconostoc mesenteroides and Lactobacillus cellobiosus were also found some predominant and as well decomposing activity in the juice. The bacteria in the juice not only decreased the sucrose content about 0.2 - 0.6 percent but were also able to produce acids and dextran, a slimy substance that could cause a problem in the processing of a sugar factories.

Abstract

Utilization of different types of soy protein in sausages : Fermented Thai sausage (saikrog esan), Vienna, Chinese sausage (Kunchieng); were studied. The acceptable levels of soy protein in sausage were examined by 24 judges which resulted in laboratory acceptance of the tested samples. These results indicated that less than 10% of soy isolate could be used in Saikrog esan; 16 - 20% of soy isolate could be used in Vienna sausage; and up to 30% of soy isolate can be used in Kunchieng. Different percentages of soy flour, soy isolate or textured soy flour were used.

สื่อสิ่งพิมพ์:pdf

Abstract

Forty two samples of soil, mud, water and animal excreta from various places within Kamphaengsaen Campus, Kasetsart University and Sue-E-Daang village, Kamphaengsaen District, Nakornpathom, Thailand were tested for methane fermentation. The results indicate that where there is deposit of organic matter there is possibility to obtain mixed methanogenic bacterial populations of both thermophilic and mesophilic types. However, acclimatization of these bacterial populations is essential for obtaining the sludge samples which generate appreciable methane gas yield. The acclimatization was performed such that selected Kamphaengsaen soil and small amount of bentonite were mixed and used as the bedding for the bacteria which were maintained on the mixture of glucose, cellulose, plant residues and nitrogen sources.

Abstract

Four tillage practices and five methods of application of 16 - 20 - 0 fertilizer at the rate of 75 kilograms per rai including broadcast and different methods of banding were investigated at the National Corn and Sorghum Research Center during August and December 1982. The experimental site had no nutsedge and Burmese grass problem. The result indicated that zero tillage caused corn plants to flower earlier than conventional tillage practice did. More plants per unit land area were recorded for a conventional tillage system in comparison to minimum and zero tillages. However, plant height and grain yield were not different among four tillage systems. Methods of fertilizer application failed to show a significant difference on all characters being recorded.

Abstract

Effect of seed maturity on field corn seed quality was studied at the National Corn and Sorghum Research Center, Nakhonrajasima province during July to November of 1979 and 1980. In order to obtain cprn seeds of thirteen different maturities, Suwan 1 variety was planted in 1979. At harvest, seed moisture content and a 100 seeds-weight were recorded. These seeds were dried to approximately 12% moisture content and stored in cold storage for the 1980 evaluation. As seed developmental stage proceeded, its moisture content decreased gradually to a value of 31.1% at physiological maturity stage. Seed weight, on the contrary, increased with seed developmental stage and reached the maximum during physiological maturity stage. The 1980 trial showed that germination and seedling vigor were increased with increasing maturity of seed being used. A satisfactory level of seed germination and seedling vigor was observed only when seed Age of 33 days after silking or older were used.

Abstract

Seven treatments of fertilizer and organic waste materiats (OWM) namely rice straw compost (RSC), activated sludge from beer factory (AS), activated sludge from whisky factory (SW), filter cake from sugar refinery factory (FC), castor meal (CM), inorganic fertilizer (F), and check (Ch) were used in the study. The results indicated that in RSC treatment, initial growth of rice as measured by dry matter of shoot and root and tiller number was very active until before flowering stage. After flowering, however, the plant showed N-dificiency symptom and slow growth were observed throughout planting period. In CM treatment, slow growth during initial growth stage was seen from plants grown in both Rangsit and Roi Et soils. After flowering, the plant in the treatment started growing rapidly until harvesting period. Relation between rice growth and yield was also observed in the experiment. Rice yield corresponded quite well with plant growth at the later growth stage. The yield could be ranked in the following order : Rangsit soil : F > CM >, AS, FC >/ SW, RSC >, Ch Roi Et soil : CM, F > AS, SW > RSC, FC >, Ch Most of released N from OWM was observed from the initial plant growth to flowering stage except that from CM which showed opposite result. If efficiency of OWM as N-source was considered, CM was regarded as the highest one when approximately 60% of its total N was available to the rice plant whereas RSC was among the lowest when only 6-8% of its total N could be utilized by the plant. In addition, nitrogen content in grain and straw of the rice grown in CM treatment was remarkedly high whereas that in RSC treatment was considerably low. It was noticeable that the rice plant grown in Rangsit soil applied with FC showed considerably high content of phosphorus in both grain and straw.

Abstract

Egg, larval, pupal and adult stages of the fruit fly, Dacus zonatus (Saunders), lasted on the averages 33.13 hours, and 7.40,11.00 and 71.00 days respectively when reared on a semiartificial diet which consisted of banana pulp, corn flour, Brewer's yeast, sugar, tissue paper, sodium benzoate, hydrochloric acid, and water. They were comparatively close to the oriental fruit fly, Dacus dorsalis Hendel, which lasted on the averages 36.13 hours, and 8.20, 11.50 and 88.40 days respectively when reared on the same diet. Riped fits sampling from trees of Singapore almond (Terminalia catappa Linn.), ma-kok-nam (Elaeocapus madopetalus Pierre), guava (Psidium guajava Linn.), and rose apple (Eugenia javanica Lamk.) in Bangkok area in july, August, December, and February showed the infestation of D. zonatus in association with D. dorsalis. Th'e ratios of adult flies of D. zonatus and D. dorsalis emerged from these fruits were 1 : 1.09, 1 : 0.07,l : 2.88 and I : 1.33 respectively. With its wide range of host and distribution, D. zonatus has become one of the major economic important pests of fruits, comparable to D. dorsalis, in this country.

Abstract

Lymphocytes and monocytes from the buffy coat of 10 adult swamp buffaloes (Bubalus bubalis) were studied. General feature of the lymphocytes was round or oval and the cell outline was slightly irregular. The nuclei were round or oval and had indentations. The cytoplasm contained abundant ribosomes. Two to ten round, oval or elongated mitochondria were seen. The small Golgi complex was situated near the nuclear indentation and was closely associated with the centrioles. There was a small quantity of endoplasmic reticulum while the number of azurophilic granules was quite variable. The monocytes were round or oval and were the largest among the cell types appearing on the electron microscope. The nuclei were lobule, round, oval or irregular round, in which consisted of fine chromatin granules, distributed compactly or loosely. A few to several dense round, oval or rod-shape granules were observed in the cytoplasm. Several round, oval or elongated mitochondria with clear cristae were seen. The centrioles and ill or well-developed Golgi complex were present near the nuclear indentation. A great number of smooth-surfaced endoplasmic reticulum were distributed on over the cytoplasm while a few rough-surfaced endoplasmic reticulum were also seen.

สื่อสิ่งพิมพ์:pdf

Abstract

Three mungbean cultivars, PHLV 18, CES ID-21, and U-Thong 1 were grown under 3 planting rates, namely, 38,400 plantslrai (50 x 25 cm. 3 plants per hill) 51,200 plantslrai (50 x 25 cm. 4 plants per hill and 50 x 12.5 cm. 2 plants per hill) and 76,800 plantslrai (50 x 12.5 cm. 3 plants per hill). It was found that number of plants per hill affected agronomic characters more distinctly than planting rates per se. When averaged across 3 cultivars, the plots planted to 4 plants per hill were later in flowering and maturity dates. They also grew taller and thus lodged more than those plots planted to 3 or 2 plants per hill. Although planting rates did not systematically affect yield and its components, dry weight of weeds per square meter was reduced significantly as planting rates increased.

สื่อสิ่งพิมพ์:pdf

Abstract

Pot experiment was established to determine the influences of three nitrogen sources (ammonium sulfate, ammonium chloride and urea) and five nitrogen rates (0,O. 64,1.28,1.92 and 2.56 gNlpot or 0,40,80,120 and 160 kgN1rai) on oven-dry forage yields, N yields and N recovery of para grass grown on Nakhon Pathom, Kamphaeng Saen, Muak Lek and Chai Badan soil series. These four soil series were the most common soils used for growing forage crops for dairy production in the western and central parts of Thailand. The experiment was conducted at Kasetsart University (Bangkhen campus) for a period of six months. Oven-dry forage yields and N yields of para grass grown on all soil series applied with different sources of N fertilizer were the highest at N rate of 2.56 gNlpot, but the highest response per unit of N fertilizer used were found at the rates ranged from 0.64 - 1.28 gN1pot. Oven-dry forage yields were increased at the same amount from all N sources and all of the soil series except Muak Lek soil, when fertilizer N were applied at low rate (0.64 gN1pot). However, oven-dry forage yields from urea N source were lower than those from other N sources when fertilizer N were applied at higher rate (1.28 - 2.56 gN1pot) on all of the soil series except Nakhon Pathom soil series which is acid soil. Oven-dry forage yields and N yields of para grass grown on Muak Lek soil series were the highest when fertilizer N were not applied. But oven-dry forage yields and N yields of para grass grown on Chai Badan soil series gave the highest response to all rates of fertilizer N. Recovery of fertilizer N in oven-dry forage yields from all soil series was the highest from ammonium sulfate N source and the lowest from urea N source. Average recovery of fertilizer N in over-dry forage yields grown on Nakhon Pathom (60%), Chai Badan (58%) and Kamphaeng Saen (55%) soil series were higher than that from Muak Lek (44%) soil series.
