Hemolysis in ED (emergency department) patients is common due to difficult blood draws. Values of serum potassium (K) become falsely elevated secondary to release of intracellular contents. Objective: The aim of the study was to establish a correction factor for factitious elevated K in samples for de adult ED. Methods: We used samples from 125 adult ED patients, in which the 2nd sample was dra...

With the increasing demand for power from the ac line and more stringent limits for power quality, power factor correction has gained great attention in recent years. A variety of circuit topologies and control methods have been developed for the PFC application. International Standards in the area of compliance of a product’s AC mains current harmonics have forced that new power supply design ...

A boost Power Factor Correction (PFC) front end converter followed by a circulating current for the soft switching flows only through the auxiliary circuit and a In recent years, dc power supplies have been widely used in industrial Lr is delivered to the capacitor C1 via transformer T. iLr (t) decreases linearly. I believe that I understand how a starting capacitor is used with an induction mo...

The global earthquake disaster happened frequently in recent years, how to guide the construction correctly in seismic area becoming a problem to be solved, while the study on the tunnel geological advanced prediction system in seismic area is limited. This paper established an integrated prediction system which was combined with engineering geology analysis and geophysical method combined with...

In 1927, E. Artin proposed a conjectural density for the set of primes p for which a given integer g is a primitive root modulo p. After computer calculations in 1957 by D. H. and E. Lehmer showed unexpected deviations, Artin introduced a correction factor to explain these discrepancies. The modified conjecture was proved by Hooley in 1967 under assumption of the generalized Riemann hypothesis....

BACKGROUND The diet of free-ranging carnivores is an important part of their ecology. It is often determined from prey remains in scats. In many cases, scat analyses are the most efficient method but they require correction for potential biases. When the diet is expressed as proportions of consumed mass of each prey species, the consumed prey mass to excrete one scat needs to be determined and ...

In this article, the need for an explicit consideration of the environment in order to address everyday competence (EC) in old age is illustrated based on an analysis of the day-to-day challenges of visually impaired older adults. Data are based on a sample of elderly adults suffering from different degrees of visual impairment (visually severely impaired vs blind, each N = 42) and a control gr...

OBJECTIVE There is an unmet need for a specific cardiovascular risk (CV) algorithm for rheumatoid arthritis (RA) patients. Lipoprotein data are often not available in RA cohorts but could be obtained from frozen blood samples. The objective of this study was to estimate the storage effect on lipoproteins in long-term (>10 years) frozen serum samples. METHODS Data were used from an inception R...

BACKGROUND AND OBJECTIVES Major burn surgery causes large hemorrhage and coagulation dysfunction. Treatment algorithms guided by ROTEM® and factor VIIa reduce the need for blood products, but there is no evidence regarding factor XIII. Factor XIII deficiency changes clot stability and decreases wound healing. This study evaluates the efficacy and safety of factor XIII correction and its repercu...
