Data stream analysis frequently relies on identifying correlations and posing conditional queries on the data after it has been seen. Correlated aggregates form an important example of such queries, which ask for an aggregation over one dimension of stream elements which satisfy a predicate on another dimension. Since recent events are typically more important than older ones, time decay should...

Coating performance is greatly influenced by the properties of the wood substrate. This study was focused on evaluating the performance of coatings on both preservative- and thermally-treated wood. A number of commercially formulated semi-transparent stains Alkyd, Alkyd-Acrylic and PU were applied on four different types of preservative treated and heat-treated wood and their performances were ...

Previous studies have demonstrated variations in volatile compound content during fruit spoilage. Infrared spectroscopy was proposed as an alternative method to discriminate the various states of decayed fruit through the makeup of their volatile compounds. Based on the infrared spectra of volatile compounds obtained from decayed grapes, this study simplified the extraction of their feature spe...

OBJECTIVE Determining dental caries' experience, prevalence and severity in students applying for degree courses at San Luis Potosi University (UASLP). MATERIAL AND METHODS A cross-sectional study was carried out involving adolescents and young adults (16 to 25 years old) applying for undergraduate courses at UASLP (approximately 10 %, n=1 027). Two standardized examiners undertook dental exa...

in this research, the effect of tension wood formation in populus nigra on its anatomical characteristics was studied. vessel element and ray frequency (n/mm²), vessel diameter and ray dimensions were measured in both normal and tension wood. furthermore, the formation of gelatinous layer (g-layer) in the fibers of tension wood was studied. the results showed that the vessel proportion and diam...

The purpose of this investigation was to find patterns (if any) that exist when comparing the dominant plant organisms atop nurse logs in two 12’x13’ quadrats along the Marsh Loop and Suspension Bridge trails at IslandWood. The intent of this investigation was to elucidate why certain plants grow on decaying wood. Two locations were chosen in the temperate second-growth forest at IslandWood. Tw...
