The growth effect of sugar supplementation was determined in 49 retarded growth calves. Calves were supplemented with sugar at 1 g/kg BW 2 times weekly for 8 weeks. Glucose tolerance tests prior to the experiment showed no difference between the retarded growth calves and normal growth controls. After sugar supplementation, the calves were classified into 4 groups characterized by high (H) or low (L) periodic changes in daily weight gain (DG) with a breakpoint of 0.8 kg/d in three periods, birth to sugar supplementation (Birth-Pre), the 8 weeks during supplementation (Pre-Post) and after feeding to delivery to market (Post-Market). The periodic DG showed a marked increase after supplementation in Pre-Post and Post-Market compared with before supplementation during Birth-Pre in 2 groups (0.93 and 1.11 vs. 0.51 kg/day for L-H-H [n=19], 0.66 and 1.19 vs. 0.42 kg/day for L-L-H [n=24]), but no difference was observed in L-H-L (n=3) and L-L-L (n=3). Peripheral blood was collected on the day before supplementation (Pre), 8 weeks after supplementation (Post) and eight weeks after cease of supplementation. The blood concentrations of both insulin-like growth factor-1 (IGF-1) and glucose showed significant increases in L-H-H and L-L-H, but decreases in non-esterified fatty acid were observed in L-H-H and L-L-L on day Post compared with day Pre, respectively (p<0.05). At delivery to market, the sugar-supplemented calves had body weights similar to the market average. The growth effect of sugar supplementation could be stimulated through rumen papillae development induce by sucrose, the main component of table sugar.

Intavas Techno Demo Farm is situated in high elevation of 1, 220 meters above sea level, with cool temperature and without pronounced dry season. The soil has low pH (5.24, average) and medium total carbon (4.3%) in the surface. Phosphorus retention is relatively high (77.5%, ave.), low cation exchange capacity (12 cmol(+) kg^<-1> ave.) and low base saturation (13%, ave.). Clay content is 45% (ave.) and bulk density of 1.1 Mg m^<-3> in average. Micrograph of the thin section of Bw_1 horizon reveals that void content is very small (6%). Voids are vughy and are not interconnected. In crossed nicol there were no clay illuviation seen. Total element analysis revealed that Intavas soils have about 60% Al_2O_3 but very low in SiO_2, 16.05% only. This indicates an advanced weathering that Si has been leached out and Al precipitated. As to the primary minerals, opaque minerals predominate with the presence of hornblende in heavy minerals. For light minerals, weathered particles predominate with the presence of mica, quartz and volcanic glass. Selective dissolution analysis reveals that Al_o is relatively high as compared to Fe_o and Si_o. However, these elements have the same pattern that irregularly decrease with depth and increase in the buried A horizon. Fe_p is relatively high followed by Al_p that significantly decreases with depth. The data show that amorphous materials are higher in surface and buried A horizons. Electron micrograph of BA shows no defined form that can be considered as amorphous materials. Bw_2 shows angular shapes that correspond to gibbsites and halloysite as indicated by spheroid configurations. X-ray diffraction pattern exhibits small and weak peak at 7 A in BA horizon. This peak corresponds to the presence of halloysite. The sharp and strong peaks at 4.8 A and 4.3 A in BA and Bw_2 horizons correspond to gibbsite. According to the selective dissolution analysis, electron microscopy and X-ray diffraction analysis, the dominant clay mineral in BA horizon is gibbsite and followed by amorphous material and small amount of halloysite. On the other hand, gibbsite dominate Bw_2 horizon followed by halloysite. Based on the physical, chemical, mineralogical and thin section analyses, the TDF soil can be classified as fine clayey, acid, isothermic, gibbsittic, Oxic Dystrudepts. It can be considered as soil with partial rejuvenation by volcanic ash material. As compared with soils without rejuvenation, this soil has higher total carbon, phosphorus retention, lower bulk density relatively, high amorphous materials in the surface and halloysite in the subsoils.Philippine soilsOxic Dystrudeptstephravolcanic glasshalloysitegibbsitedark and high humus surface

The rabbitfishes (Pisces: Siganidae) have long been considered good candidates for aquaculture. Some biological attributes including morphometric relationships (length-length, length-weight) and conditionfactors of three siganids of the Western Indian Ocean were estimated over peak April-August monsoon season in Southcoast Kenya. Specimens were caught using basket traps "malema", one of the main gearsin the traditional fishery. A total of 64, 260 and 736 specimens of Siganus stellatus, S. canaliculatus and S. sutor were recorded, with mean±standard error for total length (TL) as 16.0±0.6cm, 22.5±0.3cm and26.5±0.2cm with corresponding wet body weights (BWs) of 71.28±8.53g, 158.58±6.45g and 258.80±4.30g respectively. TL-BW relationships were best expressed by log10BW=2.597log10TL-1.356 for S. stellatus,log10BW=2.800log10TL-1.635 for S. canaliculatus and log10BW=2.716log10TL-1.484 for S. sutor with relative condition factors expressed by Kn = BW/ [(4.41x10-2) (TL2.597)], Kn = BW/ [(2.32x10-2) (TL2.800)]and Kn = BW/ [(3.28x10-2) (TL2.716)] for the three species respectively. TL and BW were significantly correlated with Kn and K. To the best knowledge of the authors, this study provides the first L-W relationship and Kn data for S. stellatus within the species geographical distribution. The overall results and equations provide useful simple tools for in-situ gauging of overall health of wild siganid populations inSouthcoast Kenya for fisheries management and assessment of potential aquaculture species.

When a person Learns many things in a society, he/she cannot learn efficiently by only the immediate learning. Learning by observation of the model becomes important. It consists of four stages. The first is the attention stage at which a learner pays attention to conspicuous characteristics from many modeling stimuli. The second is the stage at which obserbed matters are kept in the memory. The third is the movement and reproduciton stage at which is memorized. The fourth is the stage of reinforcement and motivation toward learning. These stages are closely related to learning behaviours in classes. Therefore, classes should be planned so that a learner can take these four stages to the full. This paper states the importance of the modeling theory in the computer information education at the university level from different viewpoints and does research on what situation it can be applied to.
