  • Forty-two outbred female Sprague-Dawley rats weighing 145 g were used to study the effects of a beta-agonist, cimaterol, on growth, body composition and urinary excretion of 3-methylhistidine (MH) at 3, 6 and 18 d. Cimaterol (CIM) was administered in the feed at 10 mg/kg. The growth promoting effect of CIM was most evident during the initial part of the feeding period, followed by a gradual decrease in the magnitude of the response with no significant effect at 18 d. The action of CIM was confined to skeletal and cardiac muscles with no stimulating effect on other organs. The amount of urine excretion and urinary MH excretion was reduced (p<.01) at 3 d in the CIM group. No difference was found at 6 d, followed by an increased urine excretion (p<.05) and MH excretion (p<.01) at 18 d. An inverse relationship between growth rate and urinary MH excretion suggested that the increased growth rate of CIM-fed rats during the initial part of the feeding period is primarily attributed to the decreased protein degradation rate. It was further suggested that both fractional synthesis rate and fractional degradation rate increased during the later part of the feeding period.

  • This paper presents the effects of supplementary feeding and internal parasites on the growth rates of female weaner goats raised under improved management. A completely randomized $3{\times}3{\times}2$ factorial design was used. Factors were genotype (Thai native: TN, 75% TN $\times$ 25% Anglo-Nubian: An and 50% TN $\times$ 50% AN), feeding grazing only, low (1.0% BW/d) and high (1.5% BW/d) supplementation and parasite control (undrenched and drenched). It was shown that native goats had significantly (p<0.05) higher growth rates than did the cross-bred goats from 12-24 weeks of the trial. The growth rate of goats grazing improved pasture depended on the amount of concentrate offered as a supplement. There was no significant difference in growth rates between undrenched and drenched goats. There was no interaction effect on growth rates between the treatments. Drenched goats had significantly (p<0.01) lower egg counts per gram of gastro-intestinal nematode than did undrenched goats. There was no significant difference between the treatments for blood constituents (total protein, haemoglobin, packed cell volume, eosinophils, lymphocytes, monocytes and basophils).

  • Serum biochemical values were measured in blood samples collected from 8 fasted stags from both jugular and femoral veins at 18-day intervals during antler growth. Samples were analyzed for blood substrate, enzyme activity values, minerals and electrolyte. There were no significant differences in total protein, albumin, urea, creatinine, triglyceride, glucose or cholesterol concentration between veins or sampling dates. However, total-bilirubin concentration in the jugular vein on the casting date was three times higher than on the other sampling dates (p<0.05). There were no significant differences in alkaline phosphatase, aspartate aminotransferase, and alanine aminotransferase with progressing antler growth. The highest level of alkaline phosphatase concentration was on day 55 after casting. There were no significant differences in inorganic phosphorus, sodium and chloride concentration between jugular and femoral samples. Calcium concentration was significantly higher in the femoral vein on the cutting date (55 day) than in the jugular vein (p<0.05). There were few changes in serum biochemical values. However, some electrolytes and minerals had differences during antler growth. It is suggested that despite such a big event as antler growth, blood biochemical values are not variable if feeding conditions are consistently maintained as was the case in this study.

  • It was observed that the effect of Grand E.C, on the growth of Fusarium oxysporium f. cucumerinum mycellia, which was cultured in the media with different nitrogen and carton sources, varied with it's concentrations. (1) Mycellia of F. oxysporium f. cucumerinum were grown strongly in $(NH_4)_2HPO_4\;NH_4NO_3$ and fructose media. (2) In general, the diluted Grand E.C, $ (\times\;1,000)$ effected on check of fungal growth in any type of media with the different nitrogen and carbon sources. It was disturbed the growth of fungi in $NH_4NO_3$, lactose and fructose in the diluted fungicide $(\times\;5,000)$. In the diluted solution $(\times\;10,000)$ of fungicide, somewhat increased the viability of fungi, but it was disturbed the growth in $NH_4NO_3$ and fructose media. (3) In conclusion, it was thought to be that the diluted Grand emulsion effected in check of the growth of F. oxysporium f. cucumerinum which grown some nutritional conditions.

  • The study was performed to clear the effects of thiamine, biotin, nicotinic acid, pyridoxine, inositol, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) on the mycelial growth and the sclerotial production of Sclerotium rolfsii Sacc. isolated from Magnolia kobus. The results are abstracted as follows: 1. Tested fungus was thiamine- deficient and required thiamine 20r/l for maximum growth of mycelia. At higher concentrations than thiamine 20r/l, however, mycelial growth was decreased with increasing the concentrations and was inhibited little less than that of thiamine-free control at 150r/l. 2. The effecfivenesses of the nitrogen sources on the mycelial growth under the thiamine presence were recognized in order of $NH_4NO_3>(NH_4)_2SO_4 >asparagine> KNO_3$, and on the sclerotial production were $KNO_3>NH_4NO_3>asparagine>(NH_4)_2SO_4$. The optimum concentrations of thiamine were about 12r/1 in $KNO_3$, about 16r/1 in asparagine on the growth of mycelia, and were about 8r/l in $KNO_3\;and\; NH_4NO_3,\; 16r/1$ in asparagine on the production of sclerotia. 3. After the organism began to grow, the pH value of cultral filtrate was rapidly dropped down to about 3.5. Hereafter it was slowly fallen down as the growth amount was increased, but was not depreciated below pH 2.2. 4. Nicotinic acid was not effective individually on the mycelial growth and the sclerotial formation of tested fungus without thiamine, but slight effect of it was recognized with thiamine 10r/l, even though maximum growth was shown at 7-10mg/1. Beyond that concentration, however, mycelial growth was rather depressed. 5. When ammonium sulphate or asparagine as the nitrogen sources was used, pyridoxine, biotin and inositol had not any effectivenesses on the mycelial growth and the sclerotial production of examined fungus. 6. In the concentrations of thiamine, biotin, pyridoxine and inositol, as long as thiamine was not added in those, their correlating effects on the growth of the organism were not observed at all. Equivalent or more effects on the mycelial growth were recognized in combinations of thiamin + pyridoxine, thiamine + inositol, thiamine + biotin + pyridoxine, and thiamine + biotin + pyridoxine + inositol compared with thiamino alone, and in combinations of thiamine + biotin and thiamine + biotin + inositol, mycelial growth was inhibited rather than that of thiamine alone. Sclerotial production of those combinations was increased more than that of thiamine alone in dry weight. 7, The little effects of DNA and RNA on the mycelial growth of the organism were recognized compared with the control(DNA-and RNA-free), and RNA was more effective than DNA. Maximum growth of mycelia was observed at RNA 2-6mg/1 and DNA 6mg/l. No effectivenesses on the sclerotial production were recognized in the RNA and DNA. 8. Mycelial growth of the organism was increased with increasing the concentrations of the RNA and the thiamine, that is, the effectiveness of RNA was revealed apparently under presence of thiamine, but was not shown in the sclerotial formation.

  • A method to estimate the autotrophic maximum specific growth rate is presented in this paper. First of all, the concentration of nitrifier is simulated based on the amount of N nitrified, the sludge age and the default value for the decay coefficient. Secondly the OUR of the sludge with access of ammonia is measured. The maximum specific growth rate can be calculated as ${\mu}_{max,A}\;=\;OUR_{max,A}/Y_A$. It was demonstrated that the maximum specific growth rate of autotrophic biomass is not a constants but a time variable parameter. It is concluded that using $OUR_{max,A}$ for dynamic estimating maximum specific growth rate is a good approach and that using a constant value for the maximum specific growth rate over a longer period of time could not predict the performance of activated sludge plants.

  • This study was conducted to investigate the influence of herbicides, simazine, pendimethalin, propyzamide and asulam on the growth of Zoysia matrella when they are treated at different growth stages of the plant. The reaction of Zoysia matrella to herbicides differed depending on kinds of herbicides, their concentcations, and time of treatment. Simazine at the higher concentration of 600g /l0a exhibited inhibitory effect on leaf dry matter and growth of runner when treated on April 5, 1991. The highest inhibition of leaf and runner was observed in the plot applied on May 23, 1990. The sprouting and growth of Zoysia matrella was not affected by all the concentrations of the herbicides applied on October 23,1991. Pendimethalin did not influence the growth of Zoysia matrella at he treatment of April 5. However, at the treatment of May 23, the number and growth of runner was inhibited although the plant height and leaf dry matter was not affected. When pendimethalin was treated on October 23, the growth of runner was very slightly reduced in the next year. In case of propyzamide, there was no inhibitory effect on the growth of Zoysia matrella regardless of treatment of times, methods, and dosages. Greater inhibition in the growth of Zoysia matrella was observed at higher dosage(1,ll0g /l0a)-treated plot on April 5 and all the concentrations treated on May 23. But, no inhibition was observed on the October 23 treatment.

  • Human capital and innovation capacities are essential elements and one of the sustainable approaches to driving economic growth. However, there is debate among scholars concerning these two factors in fostering economic growth. This study investigates the relationships between human capital and innovation capacity and economic growth in selected ASEAN countries, namely, Malaysia, Thailand, and Indonesia. Economists widely discussed the interrelation of human capital and innovation. A large body of literature stated that human capital is an essential factor and engine of economic growth. Innovation has become key in transforming the economic development of developing countries. We analyze human capital (HC) and innovation capacity (INC) using static panel data analysis. The data analysis shows that the fixed-effect model is the best model in this study. Further, human capital (HC) has a significant positive relationship with economic growth. Meanwhile, innovation capacity has no significant relationship with economic growth. We also found that Malaysia's coefficient of human capital and innovation capacity is higher and more efficient than in Thailand and Indonesia. In conclusion, human capital and innovation capacity are crucial elements for measuring economic growth. Skilled human capital contributes significantly to the economic growth and economic development of a nation.

  • Pantala flavescens is a dominant Odonata species in the rice fields in Korea. To determine the effects of different temperatures on its larval growth and emergence, field and laboratory experiments were conducted. Larval growth was also monitored in mono-cropping and double-cropping rice fields. The growth of larvae was monitored every week by measuring the head width. In the field experiment, no difference was found in larval growth and emergence between the control temperature and +1.9℃ of the control temperature. The larval growth was greater at 23℃ than at 20℃ laboratory temperatures, and no emergence was recorded at either temperature after eight weeks of monitoring. There was a quadratic relationship between larval growth and temperature in an incubator at five temperature regimes of 15, 20, 25, 30, and 35℃. Midseason water drainage caused the extinction of the existing individuals and newly hatched larvae dominated after re-watering in the rice fields. Larval size was greater in double-cropping fields than in mono-cropping fields in late July but the tendency was reversed in early August. The results of this study suggest that temperature warming will directly promote the larval growth of P. flavescens and indirectly influence seasonal growth via changes in water management in rice fields.

  • This experiment was carried out to find optimum ratio of $NO_3^-$ to $NH_4^+$ in nutrient solution for the growth of Phalaenopsis hybrid and find the effect of the ratio of $NO_3^-$ to $NH_4^+$ on the flower stem (inflorescence) quality. The ratio of $NO_3^-$ to $NH_4^+$ of nutrient solution used in this experiment was 100% : 0%, 90% : 10%, 80% : 20% and 70% : 30%. Phalaenopsis showed better growth when $NH_4^+$ was supplied concurrently with $NO_3^-$ as nitrogen source than supplied with only $NO_3^-$. Especially, increasing the ratio of $NH_4^+$ from 0% to 10% the fresh weight and dry weight of Phalaenopsis hybrid was highest. But, the growth of shoot and root was diminished when the proportion of $NH_4^+$ in nutrient solution was increased from 10% to 30%. Inflorescence length, the number of inflorescence and flower per plant all increased as $NH_4^+$ increased from 0% to 10% but, decreased from 10% to 30%. These results suggest that the optimal ratio of $NO_3^-$ and $NH_4^+$ in nutrient solution for the growth of Phalaenopsis including inflorescence was founded to be 90%:10%.
