Study of soil properties like field capacity (F.C) and permanent wilting point (P.W.P) plays important roles in study of soil moisture retention curve. Pedotransfer functions (PTFs) provide an alternative by estimating soil parameters from more readily available soil data. In this study, a new approach is proposed as a modification to a standard fuzzy modeling method based on the table look-up ...

Computerized systems are becoming smaller, ubiquitous and more interconnected. Netbooks to smart highways all are expected to be more autonomous and connected to each-other. Such interconnected systems have to manage information and regulate actions on their own, with minimal external guidance. A sensor network is a typical example. With scarce resources and no ready infrastructure, it forms a ...

The natural background concentration of lead (Pb) in soils in the United States ranges from 10 to 700 ppm, with an average of 20 ppm (Demayo et al., 1982). However, as a result of anthropogenic activities, soils may be contaminated with elevated levels of Pb. For example, gasoline combustion releases Pb into the atmosphere, and this Pb can be deposited· onto roadside soils. 1,225 ppm Pb ~s note...

Copper, lead, cadmium, and zinc levels were analyzed by atomic absorption spectrophotometry in surface soil, plants, and air samples taken from both sides of the major highway connecting Amman with the southern parts of Jordan. Elevated levels of the studied elements were found in both soil and plants on the east side and on the west side of the road compared with the background values. The hig...

In this paper we analyze in detail the energy consumption characteristics of the Wireless HART protocol when operated with a popular transceiver, the ChipCon CC2420. We analyze how much various factors contribute to the overall energy consumption over a longer period of 12 h. These factors include the amount of management traffic and the power levels required for various transceiver activities ...

The use of reclaimed asphalt pavement (RA) in new asphalt pavements can provide important economical savings, while reducing the negative environmental impact. The European research project PARAMIX aims to improve the techniques for hot mix recycling in plant and cold mix in situ recycling, so as to increase the amount of reclaimed asphalt and develop competitive road pavement rehabilitation te...

BACKGROUND Evidence shows an influence relationship between described symptoms of gastroesophageal reflux disorder (GERD) and emotional state. OBJECTIVE To determine the relationship between anxiety and depression with GERD in patients referred to the endoscopy unit of Bouali-Sina Hospital in Qazvin. METHODS This case-control study was conducted in the endoscopy unit of Bouali-Sina Hospital...
