Abstract

The purpose of the research is to understand the influences of ocean and atmosphere to the formation of Super Typhoon Songda 2011. Daily SST from NOAA AVHRR with spatial resolution of 0.5° in latitude and longitude was used to study upper oceanic response to the formation of Typhoon Songda. Meanwhile, 3-hourly meteorological data from ARP model with spatial coverage of 0.5° Latitude x 0.5° Longitude cover 201 x 101 points from 25° N - 20° S and 70.0° E – 170.0° E as well as 13 levels of atmospheric columns was also used in the study. The study was also supported by  MT-SAT satellite images. The result showed that from early disturbances until reaching mature stage of Typhoon Songda, SST over WNP reached averages temperature of 30˚C. Warm ocean waters continuously produce heat and moisture to the air that are necessary to fuel the genesis, development, formation and intensification of Typhoon Songda. The study also proved that light vertical wind shear (850 – 200 hPa) at about 0 – 5 knot was observed in the early development of Songda at 1800 UTC on May 19th. For the time being, weak vertical wind shear extended to the northwestern of Pacific Ocean. Thus, it made the system to moved toward northwest and reached category Super Typhoon few days later on May 26th. The study also showed the present of Monsoon trough. Monsoon trough occurred where easterly wind met the reversal southerly wind. The region was stretched from southeast to northwest part of WNP Ocean and designated by an extended low pressure area at the surface as well as extended bands of thunderstorms as observed by satellite imagery. On the other hand, potential vorticity shown in the present paper is useful to obtain an understanding of atmospheric motions and development of the upper-level disturbance. Potential vorticity maximum characterize strong vorticity and upward motion. Conversely, weak vorticity with downward motion is demonstrated by mininum potential vorticity.

Abstract

Monitoring of physiological stress in wild and/or endangered animals living in their natural habitat can be generated via measuring faecal glucocorticoid metabolites (FGCMs) through enzyme immunoassay technique. However, a careful validation of each enzyme immunoassays (EIAs) and methodological issues such as samples preservation, and extraction procedures must be a significant concern and validated because  it may influence FGCMs levels. In this present study, the aim was to carry out a biological validation to find reliable EIAs that could be used for non-invasive measurement of glucocorticoid levels in crested macaques. Moreover, we compared three different techniques of preservation: lyophilisation, oven drying and field extraction and three different solvents for extraction: 80% methanol, 90% pure ethanol and 90% commercial alcohol (isopropyl alcohol) to find the simple and practical techniques for sample processing. For hormone analysis, we colIected 189 faecal samples from wild crested macaques living in the Tangkoko-Batuangus Nature Reserve, North Sulawesi, Indonesia. The results show that biological validation can be used to validate measurement of faecal glucocorticoid which 3α,11β-dihydroxy-etiocholanolone was the most reliable EIAsfor this species. Different preservation and solvent extraction were not significantly influenced levels of FGCMs (p0.05). In conclusion, Our study highlights the importance of biological validation of FGCMassays and presents practical techniques for the non-invasive monitoring of physiological stress in crested macaques.

Abstract

Cissus quadrangularis Linn (Cq) is a rambling shrub, characterized by a thick quadrangular fleshy stem and widely used to cope with joint pain, syphilis, venereal disease, and osteoporosis. This plant is containing calcium, phosphate and phyto-oestrogens. Hence the objective of the present study was to evaluate effect of the C. quadrangularis on bone recovery of rat. Blood was drawn once each 30 days to analyze serum calcium and phosphate concentration in blood. Rats were sacrificed to analyze bone histology.  Os tibia fibula slice was stained with Hematoxylin Eosin (HE) method to observe osteoblast and osteoclast density, and Masson trichrome to observe trabeculae structure. ESP administration at longer period on treatment rats (OV-2) leads to more radiopaque  bone mass than other groups including control group  but osteoclast density is lower

Abstract

Rubber seeds have no dormancy, germinate rapidly and fungal growth is the limiting factor influencing storage period of seed viability. Solution of Polyethylene glycol 6000 (PEG 6000) have osmotic potential and osmotic adjustment that is used as a coating material is expected to be a preservative during storage. The purpose of this study was to test the effect of polyethylene glycol 6000 in inducing secondary dormancy by reducing the seeds germination and fungus growth to maintain the seed viability in storage period and to test seed viability and vigor after storage period. First stage of the study was using nonfactorial completely randomized design with four levels of polyethylene glycol with four replications, namely:PEG 6000 (w / v): 0%, 15%, 30%, 45%; The second step, was germination phase in germination tub after the storage period. The first study showed that concentration of 15% PEG 6000 to 45% were able to induced secondary dormancy by delaying seed germination from 0.67% to 0.33%, that significantly different from the 0% PEG 6000 (17.67%) that was able to reduced fungal seed from 16.33 to 26.33% andwas not significantly different in each treatment. The second study showed that PEG 6000 can maintain viability and vigor of seeds with seed germination above 97%, seedlings height 22.40 cm and number of leaves was 7.16. PEG 30% is the best concentration to increase the shelf life period of rubber seed andmaintained morphological characteristics after storage period. The higher the concentration of PEG 6000 the higher were the seed viability during shelf. The morphology and growth of the seedlings, had the same adaptability to the tub germination in planting medium.

Abstract

Fermented milk is one of important source of human nutrition, but not every one able to digest it properly, which can cause lactose intolerance. One alternative solution is milk should be fermented. Lactose in milk is broken down into glucose and galactose by the starter culture activity and decrease the digestion problem. There are milk based syrup which is potential to be improved in Indonesia as diversification product of  fermented milk.  Research has been conducted in Milk Processed Laboratory,  Agriculture Department, of Syiah Kuala University. The experiment divided in to two phase which were 1) to determine milk fementation process by different pecentage of bacteria and 2) making syrup by adding sugar  in fermented milk. Completely Random Disigned (CRD) was used based on sugar and yoghurt ratio in several species of microflora. namely Lactobacillus bulgaricus, Lactobacillus acidophillus and Streptococcus thermophillus. Te result of the first phase  showed that milk completely fermented by adding 5 percent of bacteria and significantly (p0,05)effect the pH, lactic acid level and unsignificantly effect fat and protein level. In the second phase showed that the best syrup performance is 50 percent fermented milk added with  5 percent sugar. The addition of different percentage of starter very significantly (P0,01) effect on pH, lactic acid level and also effect hedonic test. Furthermore, that treament given did not effect any of fat, protein, colour and aroma. In conclusion, percetage of sugar and starter addition will influence  the flavor of fermented milk syrup

Abstract

Surat-thani oyster, a big and thin-shell bivalve mollusks, has been registered as Geographical Indicators, GI, as its good taste and delicacy as well as nutritious. Eaten style is raw then there is high risk to face with some disease as oyster is filter feeder. Physical, chemical, microbiological and sensory qualities after the oyster meat treated with the garlic juice at 0, 2 and 3 ml, respectively were monitored. Though initial pH of the control, untreated with garlic juice, was higher compared with the sample treated with 3 ml garlic juice, pH of it (control) was significantly lower (p0.05) than the sample treated with the juice during storage. The total volatile base (TVB), chemical quality, values of all samples increased when increased storage time but not over 35 mg/100 g sample. During chilled storage, lactic acid content of all samples increased as storage time increased but the sample treated with the juice was higher compared with the control. A thiobarbituric acid reactive substance (TBARS), rancidity indicator, of the control was higher than the sample treated with the juice. K-value (%) of all oyster meats increased however; the lowest value was found in the control at end of storage, 12 days. Ammonia content of all samplesslightly increased during storage. Lactic acid content of the treated sample was higher than control after stored for 12 days. Both mesophilic and lactic acid bacteria of all samples tended to increase during storage. Mesophilic ofcontrol, sample-injected with garlic juice 2 ml and 3 ml increased from 3.89± 0.04 to 6.2±0.04, 3.62±0.18 to 5.89±0.06 and 3.57±0.02 to 6.04±0.10 log CFU/g, respectively at end of storage. Lactic acid bacteria of control andsample-injected with garlic juice 2 ml and 3 ml changed from 1.71±0.02 to 2.94±0.04, 1.79±0.09 to 4.63±0.08 and 1.84±0.04 to 4.82±0.10 log CFU/g, respectively. However, psychrophilic, coliforms, fecal coliforms, Escherichia coli,Staphylococcus aureus, Salmonella spp. and Vibrio spp. were low throughout the storage. Consumer acceptability scores were higher than borderline (5) at the end of the storage

Abstract

This study determined if parental bonding styles affect the development of emotional intelligence of student nurses. A descriptive-correlational research design was used. The Parental Bonding Instrument (PBI) developed by Parker et.al. (1979) was utilized to determine the bonding styles of the respondents’ parents interpreted as Neglectful Parenting, Affectionless Control, Optimal Parenting and Affectionate Control. The Emotional Intelligence (EI) questionnaire adapted from Weisinger’s EQ test instrument (1998) was also employed to measure the respondents’ EI in terms of self-awareness, selfregulation, motivation, empathy and social skills. To analyze the data gathered, Frequency and Percentage distribution, Chi-Square Test, and Pearson Correlational Coefficient were utilized. Results show that majority of the respondents perceived their fathers to have Affectionless Control parenting which corresponds to high protection and low care and their mothers to have Neglectful Parenting which corresponds to low care and low protection. It was found out that the parental bonding style of the respondents’ fathers has an effect only to their level of motivation and empathy. On the other hand, theparental bonding style of the respondents’ mothers affects the respondents’ EI as to self-awareness, selfregulation, motivation, empathy and social skills. Despite poor parenting, most of the respondents have moderately high to high level of EI which implies that there could be other factors that may contribute tothe development of a student nurse’s EI other than parental bonding style
