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 ...

dental anxiety is defined as an abnormal fearing or dread toward preventive or therapeutic visits by a dentist and unreasonable anxiety against dental procedures. it is estimated that dental anxiety affects one-third of the general population. its physical and cognitive symptoms may result in behavioral issues such as avoidance of early dental visits that troubles both patient and dentist. in o...

We consider a game between two polluting firms and an inspection agency, which can inspect ambient pollution levels before inspecting individual firms, but without committing itself to announced inspection probabilities. Without ambient inspections, we have a unique equilibrium. With ambient inspections, we obtain several equilibria, depending on the relative values of the environmental cost of...

Introduction: Ambient temperature is considered as a factor affecting on the body's metabolism, So that increase or decrease ambient temperature to the range thermoneutral zone (TNZ) (This temperature is 20.3°C to 23°C for covered people) lead to body metabolic changes, and maybe effective on the increase or reduce the prevalence of obesity. Our aim of this study was to review ...

A novel way of playing games called ambient gaming is defined and described. Growing out of ideas in ambient music, ambient gaming is defined as “ignorable as it is interesting” after Brian Eno’s description of ambient music. Ambient gaming is set in the context of existing games. Further, ambient games are set in a technological context, showing that the technology enabling their development i...

Energy efficiency is regarded as an important objective in a world of limited resources. The sustainable use of energy is necessary for the continuity of life styles that do not jeopardize the future. Nevertheless, due to poor information about the impact of human actions on the environment, it is hard to promote and warn for sustainability. This work focuses on the use of ambient intelligence ...

Estimating ground surface PM2.5 with fine spatiotemporal resolution is a critical technique 17 for exposure assessments in epidemiological studies of its health risks. Previous studies have 18 utilized monitoring, satellite remote sensing or air quality modeling data to evaluate the 19 spatiotemporal variations of PM2.5 concentrations, but such studies rarely combined these data 20 simultaneous...

Since I am a lawyer, let me start with a disclaimer: nothing I shall say is intended to reflect the views of my employers past or present or any professional association to which I may belong. And please don’t write any letters — unless they are addressed to me. The reason I start in this fashion is that some years ago, when I had just become a notary, I gave an interview to a charming lady fro...

cold hardiness is one of the most common adaptations of insects at low temperatures. to understand the cold hardiness strategy of beet armyworm, spodoptera exigua (hübner), six temperature treatments were tested on the last instar larvae. supercooling points of treatments were not significantly different. two sugars, glucose and trehalose, as well as three polyols, myo-inositol, glycerol and so...

the effect of hydraulic retention time in a range from 1.0-5.5 days was evaluated in a laboratoryscaleanaerobic fixed bed reactor packed with a hybrid material composed of tire rubber and zeolite. underthese conditions, cod removal efficiencies varied from 28.3% to 82.1%, respectively. over the more than 6months of operation, no clogging was observed. the results obtained demonstrated that this...
