the quality of pressure distribution over the atmosphere of the sea level and geopotential altitude at different atmosphere layers affect on many climate and meteorology phenomena of the earth surface. one of the important meteorology phenomenon is the occurrence of frost phenomenon especially late spring frost. in this surrey, occurring late spring frost days and minimum temperature during the...

A sudden dipolarization followed by long period ( 25 min) magnetic compression-like fluctuations with shorter period waves superimposed on them was observed by the WIND spacecraft in the magnetotail near midnight at 15RE from the earth on Sep 17, 1995. The spacecraft was near the boundary between the northern tail lobe and the plasmasheet. Observations of anticorrelation between the variations ...

the electrical conductivity of the earth is its physical parameter, which can be studied in global scales. the investigations of the earth's electrical conductivity are based on geomagnetic field variations. time variations of the geomagnetic field consist of long-term and short-term (transient) variations. external sources induce electric currents into the earth. the induced electric curr...

This paper identifies goal handling processes that begin to account for the kind of processes involved in invention. We identify new goal properties and mechanisms for processing goals, as well as means of integrating opportunism, deliberation, and social interaction into goal/plan processes. We focus on enterprise goals, which extend traditional design goals and knowledge goals to address sign...

This paper identifies goal handling processes that begin to account for the kind of processes involved in invention. We identify new kinds of goals with special properties and mechanisms for processingsuch goals, as well as means of integrating opportunism, deliberation, and social interaction into goal/plan processes. We focus on invention goals, which address significant enterprises associate...

To determine if changes in oxygenation and heart rate occur after surfactant, changes in these variables were recorded continuously for 15 minutes before, during, and 15 minutes after the administration of the artificial surfactant ALEC to 21 preterm infants ventilated for respiratory distress syndrome. Median (range) birth weight and gestation were 1199 (561-2680) g and 28 (21-43) weeks, respe...

Many US firms are improving their individual competitiveness by offshoring manufacturing operations, services and, increasingly, knowledge work. Although research to date has maintained that these practices are beneficial to the offshoring firm and national economies, by reducing costs and expanding markets, little is known about the longer term effect of offshoring on the rate of innovation of...
