AbstractThe operations of expansion and refinement on nondeterministic matrices (Nmatrices) are composed to form a new operation called rexpansion. Properties of this operation are investigated, together with their effects on the induced consequence relations. Using rexpansions, a semantic method for obtaining conservative extensions of (N)matrix-defined logics is introduced and applied to fragments of the classical two-valued matrix, as well as to other many-valued matrices and Nmatrices. The main application of this method is the construction and investigation of truth-preserving ¬-paraconsi

According to Lazarevich (Course of Obstetrics published in 1892), the mortality rate in the old days was 80%.

Abstract:
The increasing awareness on the effect of carbon emissions in our planet has led to several countries to adopt targets for their reduction. One way of contributing to this aim is to use and distribute electricity more efficiently. In this context, Conservation Voltage Reduction (CVR), a well-known technique that takes advantage of the positive correlation between voltage and demand to reduce energy consumption, is gaining renewed interest. This technique saves energy by only reducing customer voltages, without relying on customer actions and, therefore, can be controlled by the Distribution Ne

Abstract:
Implementing an engineering critical assessment (ECA) to guide the SCC flaw disposition is a valuable tool operators have in making a repair decision. When SCC is found by inspection, the effect of this cracking on failure stress and remaining life must be evaluated to decide what action should be taken � continued operation, type of repair, or replacement. This is not widely practiced in industry because of either the unfamiliarity of the analysis or the costs involved. One option considered during this research project was to have operators conduct a generic ECA on their entire line ahead of

Abstract:
Recommendations are often made that the operating pressure of a pipeline be reduced prior to investigating suspected mechanical damage in the field, due to the unknown severity of the dam-age. The ensuing question is: knowing only what can be inferred from in-line inspection and the characteristics of the pipeline, what is the appropriate amount of pressure reduction? A common recommendation is to lower the operating pressure to 80% of a recent high pressure level. Oper-ators may question whether the same pressure reduction is necessary or adequate for all pipelines, e.g. different Location Cl

Abstract:
There is a frequent need in the transmission industry to modify pipe work by welding on additional pipes and branches to existing pipelines. It is very expensive to shut down the pipeline during this operation, and it is therefore, customary to make these welds onto live pipelines. This procedure must be done with great care, since a burn through would allow the leak of pressurized products. However, a greater problem is the rapid cooling of any weld due to the high heat sink effect of the flowing gas. In ferritic steel pipelines, this can lead to excessive hardening of the heat-affected zone

Abstract:
This white paper presents a new approach for modeling emission inputs for dispersion modeling assessments. The approach is a paradigm shift from the current practice, which requires the simulation of source emissions by including all sources operating simultaneously for every hour during the year. This longstanding overly conservative approach does not adequately represent source emissions in some cases, especially from infrequent, non-continuously operated sources.

Abstract:
This technical note was developed by the US Army Engineer Research and Development Center–Environmental Laboratory (ERDC-EL) to provide guidance to the US Army Corps of Engineers (USACE) on implementing Endangered Species Act* (ESA) Section 7(a)(1) conservation planning, in coordination with the US Fish and Wildlife Service (USFWS) and the National Marine Fisheries Service (NMFS) during coastal engineering projects. USACE expends ~$200–$300 million each year on compliance, conservation, and other activities associated with the ESA (USACE 2022), and these expenditures often exceed those of othe
