OBJECTIVE The aim of this study was to investigate the cleaning ability of a self-adjusting file (SAF) system regarding debris and smear layer removal using ethylenediaminetetraacetic acid (EDTA) or MTAD. STUDY DESIGN In total, 45 maxillary incisor teeth were randomly divided into 2 different irrigation groups of 20 canals each and a negative control group of 5 canals. The canals in each of t...

We present a system to support human recollection with tag clouds, which are created from keywords generated by our algorithms from the use information of Google Calendar and Twitter. The main feature of our research is to weight words using the number of photos taken by users to recall impressive events. We evaluated tag clouds by comparing our approach and a comparative approach, and our expe...

In recent decades, China has been experiencing rapid economic development, population growth and urbanization. These processes have stressed the shortages of water resources in China, especially in the arid regions of northwestern China. In order to sustain the expanding cropland, people increased groundwater exploitation in these regions. The purpose of this study was to quantitatively analyze...

This paper examines lunisolar calendar anomalies in the Taiwan stock market, particularly the solar term effect. Using the Taiwan Stock Exchange Capitalization Weighted Stock Index (TAIEX), the significance of the solar term effect was tested. Statistical results showed that the lowest and the highest average stock returns are observed on Cold Dew and White Dew, respectively. Additionally, we f...

In most wheat growing moderate regions and especially in the north of Iran climate, is affected grain filling by several physical and abiotic stresses. In this region, grain filling often occurs when temperatures are increasing and moisture supply is decreasing. The experiment was designed in RCBD with split plot arrangements with four replications. Four irrigation treatments included (I0) no i...

Increasing pumping costs and declining well capacities in regions like the Southern High Plains of Texas are requiring producers to adapt cropping practices for usewith irrigation levels that vary between complete replacement of crop evapotranspiration (ET) to none (i.e., dryland production). Grain sorghum [Sorghum bicolor (L.) Moench] is a crop suited to both dryland and various deficit irriga...

Within the past years investigations have been carried out on the usefulness of ENVISAT ASAR dual polarimetric data for environmental mapping of agricultural areas. The performance of such approach is limited by the spatial resolution of the data, which is firstly too coarse for sufficient sampling of small fields often found in Europe and secondly useful features related to agricultural treatm...
