K Giants

Kinematics and abundances have been determined for a large sample of K giants in a field at ∼2 kpc from the center to study the relationship between the bulge and the halo. There are two different kinematic groups evident. The metal-poor stars have low rotation and high velocity dispersion, and so can be associated with the halo. The metal-richer stars have intermediate rotation. Our data suggest that the bulge and halo could be separate kinematical entities.

The Relationship

The relationship between birthday and deathday has been called an artifact due to the continuous depletion of the population with age. However, while the population decreases with age, the death rate increases. These two influences cancel each other at ages seventy-five to eighty-four. The decreasing population dominates at older ages, but the situation is reversed at younger ages. The results account for no more than one-third of the size of the large-sample effects observed among the elderly. There is still a 33 percent excess of deaths resulting from heart disease among married people ages seventy-five and older in the three-day period centered at the birthday.

AbstractEach child has a task that must be passed well, especially at the age of the child (12-36 months). One of the developmental tasks in toddlers is toilet training. Long-term use of diapers can cause toilet effects. This study aims to determine the relationship between diapers with the ability of toileting in children.The design of this research is Correlation with cross sectional approach. Large sample of 70 respondents. Sampling of the study using total sampling, data collection using questionnaires and calculations using Chi-square Correlation test using SPSS 16.0 error α 0.05.The results of the research variables The use of diapers in children interpreted most of the 47 children of respondents (67.1%) Did not use and almost half of the 23 respondents (32.9%) use. The ability of toileting in children is interpreted by most of the 42 respondents (60.0%) fulfilled, and almost half of 28 respondents (40.0%) are not met.Based on the calculation of Chi-square SPSS statistic shows that p value 0,000 <0,05) means that there is relationship of diaper usage with the ability of toileting in children with the closeness of cc relationship of 0.479 enough category.The results of this study concluded that almost half of them use diapers, and almost half of them do not meet the ability of toileting, the researcher suggests in the research place to put a picture or leaflet about the effect of Diaper Usage on Toileting Ability so that the wise mother in using Diapers.Keywords: diapers, toileting, children AbstrakSetiap anak mempunyai tugas perkembangan yang harus dilewati dengan baik, terlebih pada usia toddler (12-36 bulan).

There is no consensus in theoretical and empirical studies about the relationship between bank competition and stability. This research aims to investigate the relationship between bank competition and stability in the UK. The analysis has been done on a large sample of UK banks for the period 2004–2014. There is quite contrasting evidence on the bank competition and bank soundness relationship. A unified framework has been developed to assess how different factors may make it more likely that the data favor one theory over another. The results suggest that in some cases a U-shaped relationship exists between bank competition and stability. Therefore the conclusion is that in order to protect the bank from different risk exposures a moderate level of bank competition is needed.

AbstractBent-double sources, sometimes referred to as wide- or narrow-angle tails, are most likely the result of ram pressure from either the motion of the source through a dense medium or the "cluster weather." These unusual sources have long been associated with high density, high velocity dispersion, and turbulent environments of massive clusters, however a surprising number have been found in lower mass systems. We focus our attention on a sample of such sources in galaxy groups where the velocity dispersion is significantly lower. We have acquired multi-frequency radio continuum observations using the GMRT of our bent-double sample and new optical spectroscopy to measure the velocity dispersion of groups hosting these bent-double sources. Our goal is to derive an estimate of the density of the intergalactic medium in these groups. Here, we present GMRT data for one source in our sample.

The Relationship

We revisit the predictive ability of dividend changes for firms’ future earnings and extend the literature by examining the effect of management forecasting ability. Although prior studies have examined the relationship between dividend changes and future earnings, the empirical evidence is mixed. The belief that dividend changes have implications for future earnings depends on the assumption that managers can accurately assess future earnings prospects. In this regard, we posit that the predictive ability of dividends can vary with managers’ forecasting ability. Analyzing a large sample of Japanese dividend-paying firms, we find that dividend changes, particularly dividend increases, are positively associated with increases in future earnings. Consistent with our hypothesis, this positive association is more pronounced for firms with high-forecasting ability managers. Our findings support the signaling theory of dividend changes and indicate that management forecasting ability has a moderating effect on the linkage between firms’ dividend changes and future earnings.

Detecting Method

The curved structural plate components have been widely used in petroleum, natural gas, chemical industry, and other industries fields, monitoring and detecting the curved structural plate components flaw has a great significance for improving the components integrity, reliability and lifespan in service. Based on the elastic wave fundamental theory, elastic wave equations, and phase velocity dispersion characteristic curves in curved plate component, the article gives the phase velocity practical detecting method. By using thecomsolfinite element software, the author proposed a wave propagating forward modeling analytical method, which gives a guidance to study the relationship between the wave and the flaw. By adopting the ellipse algorithm, the article proposed a positioning and imaging method which was used to locate the flaws position and distinguish the flaws direction. Based on the theoretical and technical analysis above, a number of experiments has been done, and the results shows that the detecting and imaging method can locate and image the flaws position and its geometrical morphology precisely for the curved plates flaw detecting.
