Single real transformation matrices applied to double three-phase transmission lines
(Elsevier B.V. Sa, 2008-10-01)
Single real transformation matrices are tested as phase-mode transformation matrices of typical symmetrical systems with double three-phase and two parallel double three-phase transmission lines. These single real ...

Direct determination of iron and manganese in wine using the reference element technique and fast sequential multi-element flame atomic absorption spectrometry
(2008)
A procedure is proposed for the direct determination of manganese and iron in wine employing fast sequential flame atomic absorption spectrometry and the reference element technique to correct for matrix effects. Cobalt, ...
Plasma matrix metalloproteinase-9 levels, MMP-9 gene haplotypes, and cardiovascular risk in obese subjects
(2016-06-01)
Plasma matrix metalloproteinase (MMP)-9 is a predictor of cardiovascular mortality, and MMP-9 polymorphisms affect plasma MMP-9 levels. However, no study examined whether MMP-9 haplotypes affect MMP-9 levels in obese adults. ...
Continuous set model predictive control for energy management of modular multilevel matrix converters
(IEEE-INST Electrical Electronics Engineers, 2022)
The modular multilevel matrix converter (M3C) is an
ac to ac power converter composed of 9 arms and is proposed
for high power applications such as motor drive and wind energy
conversion systems. Energy Control of the ...

Collagen Hydrolysate Intake Increases Skin Collagen Expression and Suppresses Matrix Metalloproteinase 2 Activity
(MARY ANN LIEBERT INC, 2011)
The effect of daily ingestion of collagen hydrolysate (CH) on skin extracellular matrix proteins was investigated. Four-week-old male Wistar rats were fed a modified AIN-93 diet containing 12% casein as the reference group ...
Modal decoupling of overhead transmission lines using real and constant matrices: Influence of the line length
(2017-11-01)
The Clarke's matrix is a well-known real and constant transformation matrix used for modal transformation in three-phase transmission lines modeling. Although modal analysis has been widely discussed in the technical ...
Development of a reference material for copper and iron in wine
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2008)
Reference materials are essential tools to achieve comparability and traceability between measurements. However, reference materials in food matrices are scarce. in this article, the development of a reference material for ...
