Most of existing mobile services were designed based on the client/server architecture. Those mobile services neither paid much attention to mobile users’ interactions with their environments nor considered the cooperation efforts between the mobile users in a dynamic peer group. In this paper, the notion of ambient e-services is defined to identify a new scope of mobile e-services. The notable...

Seoul is one of the most severe smoggy cities in the world. During summer afternoons, the fine particles formed by photochemical reactions could contribute visibility reduction. The formation and growth of secondary ambient aerosols might be affected by primary air pollutants and by meteorological factors. In this work, the photochemical reaction of Seoul ambient air was investigated in indoor ...

The objective of this study was to investigate the influence of ambient temperatures on carcass characteristics of lambs fed concentrate diets with or without NaHCO3 supplementation. A slaughter study was carried on 12 male Black Belly Barbados lambs randomly drawn from a growth trial (35 weeks). The lambs were divided into four equal groups and allotted in a 2×2 factorial design. The lambs wer...

the evaluation of treatment characteristics and sludge properties of an upflow anaerobic sludge blanket (uasb) process was investigated using a pilot-scale 1.15 m3reactor. the uasb, inoculated with digester sludge, was operated at a hydraulic retention time of 8 h at sewage temperatures ranging from 10.6 to 27.7 °c for more than 1100 days. the stable removal efficiencies for total codcr and ss...

Ozone is a powerful oxidizing agent which is responsible for more damage to vegetation than any other air pollutant. In this study, leaf growth, photosynthesis, and carbohydrate content were analysed during the seed-filling growth stage of field-grown soybeans exposed to ambient air and 1.2 times ambient ozone concentration using a Free Air Concentration Enrichment (FACE) facility. By contrast ...

The experimental enclosure of an Antarctic planktonic community in a large (35 m3) mesocosm moored in Johnson’s Dock (62° 39.576’ S, 60°22.408’ W, Livingston Island, Bransfield Sector, Antarctica) was followed by a large phytoplankton bloom. This bloom, dominated by the large diatom Thalassiosira antarctica, reached a biomass 1000-fold greater than in the ambient waters. The net growth rate of ...

Three experiments were conducted to investigate the effects of thermal stress and dietary Cr on growth performance and physiological variables in weanling pigs. In Exp. 1, a total of 54 pigs (BW of 5.95 +/- 0.84 kg) were allotted to a 2 x 3 factorial arrangement using 2 ambient temperatures (23.7 or 40.5 degrees C during d 14 to 28 postweaning) and 3 dietary concentrations of Cr (0, 1,000, or 2...

The Coronavirus disease 2019 (COVID-19) was identified in late 2019 and has gradually spread to all countries. Following the outspread of this virus as a community-acquired disease, many researchers have been trying to identify various factors involved in the transmission of the virus, as well as the ways to prevent its transmission from person to person. For example, researchers have found tha...
