BACKGROUND Peperomia pellucida is popularly known as coraçãozinho in the Brazilian northeast and is used in the treatment of abscesses, furuncles, and conjunctivitis. Our work aimed to determine the term of the development stages and the species cycle in the four seasons of the year (complete development, beginning of bloom, complete bloom, and seed set), verifying the plant's therapeutic profi...
A 2-year field study was conducted to determine the influence of the timing of application and different slow release nitrogen (N) sources with different nitrogen rates on the growth and quality of a turfgrass mixture. Three different timings were used for nitrogen application: annually, once every 3 months, and once every 6 months. Three nitrogen sources (ammonium nitrate and two slow-release ...
Background Active commuting to school (ACS) can be a significant source of physical activity and provide many health benefits. Objective This study identified the potential to increase physical activity levels by promoting ACS in Finnish schools and evaluated the effects of season, distance and age on ACS. Design Data were collected with a questionnaire from 5,107 students, aged 10-16, in 45 co...
The water quality of Pauri District of Uttarakhand, India has been assessed during preand postmonsoon seasons to express the suitability of water for drinking purposes. The values of turbidity and iron exceed the permissible limit prescribed by Indian Standards for drinking purpose. Some sites were also contaminated with large number of total and fecal coliform bacteria. Piper diagrams exhibit ...
We examine the impact of El Niño–Southern Oscillation (ENSO) on surface ozone abundance observed over the continental United States (U.S.) during 1993–2013. The monthly ozone decreases (increases) during El Niño (La Niña) years with amplitude up to 1.8 ppb per standard deviation of Niño 3.4 index. The largest ENSO influences occur over two southern U.S. regions during fall when the ENSO develop...
Measurement of 7Be depositional fluxes at Granada, Spain (37 degrees 10'50''N-3 degrees 35'44''W, altitude 670 m) in the period 1995 through 1998 indicates substantial variations between the four seasons and also between corresponding seasons in different years, ranging from 23.6 to 242 Bq m(-2) per season. A strongly positive correlation with precipitation is shown, which explains about 70% of...
Feedstock quality of switchgrass for biofuel production depends on many factors such as morphological types, geographic origins, maturity, environmental and cultivation parameters, and storage. We report variability in compositions and enzymatic digestion efficiencies for three cultivars of switchgrass (Alamo, Dacotah and Shawnee), grown and harvested at different locations and seasons. Sacchar...
