T he 1998 Purdue Land Values survey indicates that the value of an acre of average bare Indiana cropland was $2,155 per acre in June 1998, $55 more than the all-time peak reached in 1981. This is an increase of $158 per acre, or approximately 8 percent, over the value reported in 1997. In each of the past five years, annual increases in the value of this land have ranged from about $100 to over...
The Las Campanas Redshift Survey (LCRS) is among the first galaxy redshift surveys to sample a reasonably fair volume of the local Universe. On the largest scales (≫ 100 h Mpc), the galaxy distribution appears smooth; on relatively small scales ( < ∼ 10 h Mpc), the LCRS tends to confirm the clustering characteristics observed in previous, shallower surveys. Here, however, we concern ourselves p...
To efficiently fuse multi-spectral (MS) and panchromatic (PAN) images acquired from THEOS satellite, the authors offer proper parameters to improve IHS fusion technique based on its spectral responsivity. This concept was originally contributed by Tu et al., applied to IKONOS image fusion. Red and NIR bands of THEOS imagery with lower response were adjusted to be higher and close to the respons...
We have started a search for High Redshift Radio Galaxies (HZRGs) in an area covering 7 sr by selecting a sample of Ultra Steep Spectrum (USS) sources with a low flux density cut-off S1400 > 10 mJy and a steep spectral index cut-off of α < −1.3 (S ∝ ν) from the WENSS, NVSS and TEXAS surveys. Our first results for 27 sources show that we are almost twice as effective in finding HZRGs than than s...

abstract the main purpose of this study was to investigate whether there was any significant difference between the speaking achievement of learners who were trained by means of consciousness raising of sociolinguistic skills and that of learners who were trained without the above mentioned task. the participants of this study consist of 60 intermediate level students participating languag...
abstract: research purpose: the purpose of this research is to identify academic databases assessment factors and criteria at law and political science majors. the necessity of this research is to distinguish academic databases assessment factors and criteria and to identify the most important ones and rank them in order to select an appropriate database according to students’ and faculty memb...
This article reports data concerning the Internet-related activities and interest for Ironman Triathlon competition. Google Trends (GT) was used and mined from 2004 onwards. The interest for Ironman Triathlon was found to be cyclic over time. The Triathlon-related Internet activities negatively correlated with the number of finishers per year (Pearson׳s correlation r=-0.690, p-value<0.05), whil...
A Health Exhibition lias been lield at tlie Drill Hall, Leeds, and lias attracted mucli attention. The Public Health Department was especially instructive and included a model hygienic shop counter, fly-proof and ice-cooled, the model cow shed, a smoke-recording apparatus, a demonstration of food values, and a dozen other features conveying lessons to the eye at once. Personal cleanliness, as a...
