Full textAbstract:
Sand mining which continuously done may cause the sand of amount in the bottom of river decreasing and may result, to the destruction of the river if occured for a long period. Revegetation activity must be done on some former sand mining river boundaries. Acacia (Acacia mangium) might be able to grow in low nutrient soil. The purposes of this research is to get information about sub soil and coconut charcoal granting effects towards acacia seedling growth on former sand mining medium.The research showed that the interaction of the added sub soil and coconut shell charcoal is significant to the heightand diameter parameter of acacia seedling while sub soil addition is significant to Dry Weight Total (DWK) parameter. Interaction of 250 g sub soil, 60 g charcoal on 750 g sand is the best treatment to enhance seedling tall growth for about 88.73%. Interaction of 750 g sub soil on 250 g sand is the most significant treatment for diameter parameter for about 71.21% diameter growth. The best treatment for Dry Weight Total (DWK) is shown by interaction of 250 g sub soil and 250 g charcoal on 500 g sand. Charcoal granting independently is not significant to addition acacia seedling growth. The addition of sub soil only showed the best result of 750 g sub soil granting with diameter growth around 71.21%.
Key words: Acacia mangium. Willd., charcoal, sand mining, sub soil

Full textAbstract:
Four experiments examined the role of meaning frequency (dominance) and associative strength (measured by associative norms) in the processing of ambiguous words in isolation. Participants made lexical decisions to targets words that were associates of the more frequent (dominant) or less frequent (subordinate) meaning of a homograph prime. The first two experiments investigated the role of associative strength at long SOAs (Stimulus Onset Asynchrony) (750 ms.), showing that meaning is facilitated by the targets' associative strength and not by their dominance. The last two experiments traced the role associative strength at short SOAs (250 ms), showing that the manipulation of the associative strength has no effect in the semantic priming. The conclusions are: on the one hand, semantic priming for homographs is due to associative strength manipulations at long SOAs. On the other hand, the manipulation of the associative strength has no effect when automatic processes (short SOAs) are engaged for homographs.

The objective of this research was to study the potential of cherry leaf extract as natural sanitizer agent for Alabio eggshell in hatching process. A number of 533 of Alabio hatching eggs were used in this study. Hatching eggs produced from College of Vacational Studies IPB University, were collected three times a day. Three hundred thirty-three hatching eggs were divided into five treatment groups. The first group was considered as control, the second was dipping into commercial disinfection, and the third and the fifth gruop were dipping into cherry leaf extract 250 ppm, 500 ppm, and 750 ppm respectively. The results showed cherry leaf extract has secondary metabolite compounds : alkaloids, flavonoids and tannins. All of these secondary metabolite compounds have a role as antibacterial agent. cherry leaf extract 750 ppm shows the same potential as commercial disinfectants in reducing the microbial population in eggshells. The dipping treatment of 750 ppm cherry leaf extract in alabio duck hatching eggs resulted in the lowest embryo mortality rate compared to other treatments (9.3%).
Key words: Alabio duck, cherry leaf extract, hatchery, total plate count of eggshell

Full textAbstract:
Broiler chickens were fed starter diets containing 0, 250 or 500 g kg−1 naked oat and, from 29 to 40 d of age, grower diets with 0, 250, 500 or 750 g kg−1 naked oat. All diets included an enteric antibiotic and water-miscible forms of vitamins A, D, E and K. Broiler performance, as evaluated by weight gain and feed:gain ratio, was as good as or better than the corn-soy control diet with up to 500 g kg−1 naked oat in the starter diets. A starter-by-grower diet interaction showed that weight gain was independent of oat level in the grower diet of birds previously fed naked oat, but gain was impaired by higher levels of oat following an oat-free starter diet. Carcass quality improved with increasing oat level in the starter diet by a decrease in abdominal fat and a decrease in oxidation of thigh meat lipids. Key words: Oat (naked), growth, carcass fat, broiler chicken

Full textAbstract:
Previous results supported the notion that estrous cycles in Syrian hamsters are responsive to the general availability of metabolic fuels, rather than to either fatty acid or glucose availability per se. To test this idea, we monitored estrous cycles in hamsters that were fed ad libitum and treated with a range of doses of 2-deoxy-D-glucose (2-DG), an inhibitor of glucose utilization. Hamsters treated with 2-DG at doses ranging from 750-1,250 mg/kg showed normal estrous cycles, but higher doses (1,750 or 2,000 mg/kg) induced anestrus. While it is clear from these data that estrous cycles are affected by glucoprivation, it is not clear whether they are responsive to decreased fatty acid availability. Groups of hamsters were fed ad libitum and treated with a range of doses of methyl palmoxirate (MP), an inhibitor of fatty acid utilization. Some of the hamsters that received the highest doses became torpid and thus were not tested for lordosis. None of the euthermic, MP-treated hamsters became anestrous. Other experiments examined the role of glucose availability in fasted hamsters. Hamsters with a high body fat content were protected from fasting-induced anestrus. In contrast, fat food-deprived hamsters treated with low doses of 2-DG (750 mg/kg) became anestrous. Thus fatty acids mobilized from adipose tissue did not prevent fasting-induced anestrus when glucose utilization was blocked. One interpretation is that during fasting fatty acid utilization spares glucose for other tissues involved in the control of estrous cycles.(ABSTRACT TRUNCATED AT 250 WORDS)
