in today’s highly competitive manufacturing environment, an effective supplier selection process is very important for the success of any business organization. selection of the best supplier is always a difficult task for the purchasing manager. suppliers have varied strengths and weaknesses which require careful assessment by the purchasing manager before selecting and ranking them. any suppl...

project selection is considered as an important problem in project management. it is multi-criteria in nature and is based on various quantitative and qualitative factors. the main purpose of this paper is to present a new rank-based method for project selection in outranking relation. according to this approach, decision alternatives were clustered in the concordance matrix and the discordance...

introduction: this study was conducted to evaluate prevalence and risk factors for diagnostic discordance for osteoporosis due to different t-scores of lumbar spine and femoral neck. methods: in this cross sectional study demographic, anthropometric and risk factors for osteoporosis were derived from a database on 3,039 post-menopausal women who underwent bone densitometry for the first time i...

BACKGROUND Twins, compared to singletons, have an increased risk of perinatal mortality and morbidity, due mainly to a higher prevalence of preterm birth and low birthweight. Intrauterine growth restriction (IUGR) is also common and can affect one or both fetuses. In some cases, however, one twin is much smaller than the other (growth discordance). Usually, high birthweight discordance is assoc...

The discordance of U–Th–Pb isotopic systems in geochronometers, and how such data are interpreted, still major issues the geosciences. To better understand disturbance systems, this impacts derivation geologically-meaningful ages, previously studied discordant monazite from ultrahigh temperature paragneiss Archean Napier Complex (Antarctica) have been investigated. Monazite grains were characte...

Isotopic discordance is a common feature in zircon that can lead to an erroneous age determination, and it is attributed to the mobilization and escape of radiogenic Pb during its post-crystallization geological evolution. The degree of isotopic discordance measured at analytical scales of ~10 μm often differs among adjacent analysis locations, indicating heterogeneous distributions of Pb at sh...

BACKGROUND Diagnostic discordance for osteoporosis is the presence of different categories of T-scores in 2 skeletal sites of an individual patient, falling into 2 different diagnostic categories identified by the World Health Organization classification system. OBJECTIVES To evaluate the prevalence and risk factors for T-score discordance between spine and total hip measurement sites. METH...
