Cursa continuă pentru reducerea dimensiunilor fizice în circuitele integrate este limitată în prezent de considerente fizice, tehnologice şi economice. Subiectul acestei lucrări este trecerea în revistă în primele două secţiuni a unora dintre problemele apărute datorită reducerii dimensiunilor tranzistoarelor şi a prelucrării tehnologice, precum şi a principalelor probleme întâlnite în proiecta...

The aim of this paper is to generalize the‎ ‎notion of almost valuation domains to arbitrary commutative‎ ‎rings‎. ‎Also‎, ‎we consider relations between almost valuation rings ‎and pseudo-almost valuation rings‎. ‎We prove that the class of‎ ‎almost valuation rings is properly contained in the class of‎ ‎pseudo-almost valuation rings‎. ‎Among the properties of almost‎ ‎valuation rings‎, ‎we sh...

The aim of this paper is to generalize the‎‎notion of pseudo-almost valuation domains to arbitrary‎ ‎commutative rings‎. ‎It is shown that the classes of chained rings‎ ‎and pseudo-valuation rings are properly contained in the class of‎ ‎pseudo-almost valuation rings; also the class of pseudo-almost‎ ‎valuation rings is properly contained in the class of quasi-local‎ ‎rings with linearly ordere...

The present paper reviews activity in environmental valuation by examining trends in publication rates over the past three decades. It also provides an overview of the demand for environmental valuation by academic markets and by policy markets. The results of this historical analysis suggest that there is not as much use of environmental valuation in policy analysis as could be expected given ...

Embedding is the widely-observed phenomenon that a good is assigned a higher value if evaluated on its own rather than as part of a more inclusive set. Embedding is considered a serious problem affecting the quality of many environmental management and health risk policy judgments. This paper presents the results of an experiment involving of a structured, small-group approach for conducting en...
