The response of two legume crops (hyacinth bean and Kidney bean) to the parasitism of field dodder (_Cuscuta campestris_)

Abstract: Microscopic examinations and chemical studies were performed to study the response of two legume crops, hyacinth bean (_Lablab purpureus L._) Sweet and kidney bean (_phaseolus vulgaris L._) to the filed dodder (FD) (_Cuscuta campestris Yuncker_) parasitism. Hyacinth bean, showing no effective resistance mechanisms,was found to be a highly susceptible host to FD. However, kidney bean, displaying resistant reactions towards the parasitism of FD,was found to be an incompatible host.The possible reasons for the resistance of kidney bean to FD were anatomical (hypersensitivity) and chemical (high contents of phenolic acids and lignin) stimulated defence mechanisms, which developed during the actual intrusion of FD haustorial cells inside its tissues

A new method for the inversion of atmospheric parameters of A/Am stars

We present an automated procedure that derives simultaneously the effective temperature $T_{eff}$, the surface gravity logg, the metallicity [Fe/H], and the equatorial projected rotational velocity vsini for "normal" A and Am stars. The procedure is based on the principal component analysis inversion method of Paletou et al. (2015a). A sample of 322 high resolution spectra of F0-B9 stars, retrieved from the Polarbase, SOPHIE, and ELODIE databases, were used to test this technique with real data. We have selected the spectral region from 4400-5000\AA\ as it contains many metallic lines and the Balmer H$\beta$ line. Using 3 datasets at resolving powers of R=42000, 65000 and 76000, about 6.6x$10^6$ synthetic spectra were calculated to build a large learning database. The Online Power Iteration algorithm was applied to these learning datasets to estimate the principal components (PC). The projection of spectra onto the few PCs offered an efficient comparison metric in a low dimensional space. The spectra of the well known A0- and A1-type stars, Vega and Sirius A, were used as control spectra in the three databases. Spectra of other well known A-type stars were also employed in order to characterize the accuracy of the inversion technique. All observational spectra were inverted and atmospheric parameters derived. After removal of a few outliers, the PCA-inversion method appears to be very efficient in determining $T_{eff}$, [Fe/H], and vsini for A/Am stars. The derived parameters agree very well with previous determinations. Using a statistical approach, deviations of around 150 K, 0.35 dex, 0.15 dex, and 2 km/s were found for $T_{eff}$, logg, [Fe/H], and vsini with respect to literature values for A-type stars. The PCA-inversion proves to be a very fast, practical, and reliable tool for estimating stellar parameters of FGK and A stars, and deriving effective temperatures of M stars.Comment: 16 pages, 9 figures.

The Effect of Cash Dividend, Retained Earnings, and Stock Price of Manufacturing Company Listed in Indonesia Stock Exchange

This study aims to determine the effect of cash dividends per share, retained earnings per share, earnings per share, and leverage on the stock price of manufacture industry in Indonesia from 2008-2012. Research used secondary data in which the source was obtained indirectly through an intermediary medium or data processed from literatures and reports associated with this research. Independent variables in this study (x) are cash dividends per share, retained earnings per share, earnings per share, and leverage, while the dependent variable (y) is stock price. The samples used were 23 companies with purposive sampling method. The empirical results of this study indicate that cash dividends per share, retained earnings per share, earnings per share, and leverage has significant effect on the stock price. It is therefore the higher stock price will attract investors to invest their money. Hence, companies and investors need to attend cash dividends per share, retained earnings per share, earnings per share, and leverage as factors that affect the increase or decrease of the stock price

The Influence of Life Expectancy in the Determination of Pension Fund Investments

Preparating one's retirement is important for many people, because an employee will often have no salary anymore after retiring, but his/her daily needs are still remained. It is not easy to calculate or estimate the amount of investment funds that must be saved during the active working years to make up for the lack of funds after one's retirement. This is still the case, even when the case when he/she will receive a pension from the company where he/she worked. In this research we further examine how the life expectancy plays an important role in calculating the amount of necessary fund investments. The results of these calculations are compared with the results without life expectancy. From this analysis, it can be concluded that the required pension fund investments calculated with the life expectancy is much less than the one without life expectancy. This happens because the required pension fund investments are only estimated by assuming that he/she is still alive.Keywords: present value, annuity, pension, investmentPersiapan memasuki usia pensiun penting untuk dilakukan mengingat seorang karya- wan tidak akan mempunyai pemasukan dari gaji setelah dia pensiun, tapi pengelu- aran untuk kebutuhan hidup sehari-hari masih tetap ada. Kesulitan yang sering muncul adalah menghitung berapa besaran dana investasi yang harus dilakukan pada saat masih aktif bekerja supaya mencukupi kekurangan dana setelah seorang karyawan pensiun meskipun ia telah menerima juga tunjangan pensiun dari pe- rusahaan tempatnya bekerja. Pada penelitian ini ditelaah lebih lanjut bagaimana ekspektasi hidup berperan dalam menghitung besaran dana investasi ini. Hasil per- hitungannya dibandingkan dengan perhitungan biasa yang tidak menerapkan ek- spektasi hidup di dalamnya. Dari hasil analisa, dapat disimpulkan bahwa besaran dana pensiun yang dihitung dengan menerapkan ekspektasi hidup, jauh lebih kecil dibandingkan dengan besaran dana pensiun yang dihitung tanpa ekspektasi hidup, karena antisipasi dana investasi pensiun hanya dilakukan selama orang tersebut diasumsikan masih hidup
