In Vitro Fermentation Characteristics and Rumen Microbial Population of Diet Supplemented with Saccharomyces Cerevisiae and Rumen Microbe Probiotics

The objective of this study was to select three strains of probiotic Saccharomyces cerevisiae and to evaluate the effect of S. cerevisiae and rumen bacteria isolate (MR4) supplementation and their combination on rumen fermentability and rumen microbial population. Experiment 1 was designed in a 4 x 5 factorial randomized block design with 3 replications. The first factor was S. cerevisiae strain consisted of control treatment (without S. cerevisiae supplementation), NBRC 10217, NRRL Y 567 and NRRL 12618, and the second factor was incubation time consisted of 0, 1, 2, 3, and 4 h. Ration was basal ration for feedlot with forage to concentrate ratio (F:C)= 60:40. Dosage of each treatment with S. cerevisiae was 5 x 1010 cfu/kg ration. Experiment 2 was designed in randomized block design with 4 treatments: P0= basal ration of feedlot; P1= P0 + S. cerevisiae; P2= P0 + MR4 isolate (5 x 107 cfu/kg ration); P3= P0 + S. cerevisiae and MR4 isolate. The result of experiment 1 showed that supplementation of S. cerevisiae NRRL 12618 had the highest S. cerevisiae population and increased rumen bacterial population. This strain was selected as probiotic in experiment 2. The result from experiment 2 showed that probiotic supplementation stabilized rumen pH and produced the highest NH3 concentration (P<0.05) and bacterial population (P<0.05). As compared with control, all treatments reduced protozoa population (P<0.05). Combination of S. cerevisiae and MR4 probiotics produced the highest total volatile fatty acids (VFA) and isovalerate (P<0.05). It was concluded that strain S. cerevisiae NRRL 12618 had potential as probiotic yeast. Supplementation with this strain increased fermentability, rumen isoacid and decreased A:P ratio. Those abilities could be improved with MR4 rumen isolate probiotic

Characteristics Overview of Mother with Perinatal Death at Dr. Soetomo Hospital in 2015

Objectives: to determine the frequency distribution of perinatal mortality and maternal characteristic features in terms of age, parity, gestational age and pregnancy complications in Dr.Soetomo Hospital Surabaya in 2015. Materials and Methods: A descriptive study conducted by collecting data on patients who experienced perinatal mortality of infants born from January to December 2015 in Dr. Soetomo, Hospital Surabaya. Samples were collected using total sampling. The samples must meet the following criteria: mothers of infants with perinatal mortality in Dr. Soetomo Hospital, Surabaya, from January to December 2015.Results: There were 206 perinatal deaths out of 1018 births in Dr. Soetomo during 2015, of which 58% was live birth and 42% was stillbirth. Most of perinatal mortality found in the preterm gestational age as much as 78%, and gestational age 28-<37 weeks (58%). Most of perinatal mortality occured in infants with less than 1500 grams birth weight, which was as much as 53% of all perinatal deaths and infant whose birth weight from1500 to 2500 grams was about 29%. Most perinatal mortality found in multigravida (54%) and in infants whose mothers experienced preeclampsia in pregnancy complications (35%), followed by infant mortality in women with non-obstetric complications (23%).Conclusion: Perinatal mortality in Dr. Soetomo Hospital was mostly found in multigravida mothers, 16-35 years old maternal age, 28-37 weeks gestational age and those with complications of preeclampsia

Characteristics of Se'i (Rotenesse Smoked Meat) Treated with Coconut Shell Liquid Smoked and Citrus Aurantifolia Extract

The objective of this study was to investigate the effect of Citrus aurantifolia extract (CAE), coconut shell liquid smoke (CSLS) and the combination of CAE and CSLS (CACS) on se'i characteristics. A completely randomized design was assigned in this experiment. Treatments used were: se'i treated with 5% (v/v) CAE, CSLS 5% (v/v), (CAE : CSL 1:1) )/ (CACS) and untreated se'i as a control (C). Parameters measured were: aroma, color, taste, pH, residual nitrite, total bacterial count, Coliform, Staphylococcus aureus, Escherichia coli, and Salmonella. The data of aroma, color, and taste were analyzed by using Kruskal-Wallis test followed by Mann-Whitney test. The pH, residual nitrite, and bacterial data were analyzed with analysis of variance (ANOVA) followed by least significant differences test. Results showed that CAE caused the highest score at both aroma and taste (P&lt;0.05). CSLS caused the lowest residual nitrite (27 ppm) (P&lt;0.05). Application of CAE and CACS could reduce total bacteria (P&lt;0.05) at least 1 log. Color, pH, and Coliform number were not significantly different. S. aureus, E. coli, and Salmonella were negative in all se'i samples. CAE gives the best organoleptics and bacteriological characteristics while CSLS is more effective in reducing nitrite

The Impact of Personal Characteristics and Intrinsic Motivation on Creative Behavior Among Indonesian Radio Station Managers

The main purpose of the article is to increase understanding in some personal characteristics affecting creative performance among Indonesian radio station managers&rsquo; leadership context. Using creativity-relevant personal characteristics and motivation as input model, the authors identified that both of these two variables are positively related to creative performance. The study hypothesized that Leader-member exchange (LMX) moderate the relationship between personal characteristics and creative performance. Among a sample of 283 Indonesian radio station managers, results found that creativity-relevant personal characteristics and intrinsic motivation were positively related to creative performance when managers&rsquo; perception of followers&rsquo; work contribution toward them (as the second dimension of LMX) was high

Measured unsteady transonic aerodynamic characteristics of an elastic supercritical wing with an oscillating control surface

Transonic steady and unsteady aerodynamic data were measured on a large elastic wing in the NASA Langley Transonic Dynamics Tunnel. The wing had a supercritical airfoil shape and a leading-edge sweepback of 28.8 deg. The wing was heavily instrumented to measure both static and dynamic pressures and deflections. A hydraulically driven outboard control surface was oscillated to generate unsteady airloads on the wing. Representative results from the wind tunnel tests are presented and discussed, and the unexpected occurrence of an unusual dynamic wing instability, which was sensitive to angle of attack, is reported
