We study the self-duality operator on conic 4-manifolds. The self-duality operator can be identified as a regular singular operator in the sense of Brüning and Seeley, based on which we construct its parametrizations and closed extensions. We also compute the indexes.

The indexes of multifactor productivity for two-digit manufacturing sectors prepared by the Bureau of Labor Statistics for sectors in manufacturing have been revised and extended to cover the 1949–92 period. These indexes, also called the “KLEMS” multifactor measures, compare changes in output to changes in a composite of all the inputs used in production—capital, labor, energy inputs, nonenerg...

Twenty studies examining the reliability of assessment devices and outcome measures in therapeutic research were reviewed and analyzed. The 20 investigations contained 215 quantitative reliability values published in either the American Journal of Occupational Therapy or Physical Therapy during the past 5 years. The reliability studies were classified as interrater, intrarater, test-retest, or ...

Birth weight and gestational age are important measures of a newborn's intrinsic health, serving both as outcome measures and explanatory variables in health studies. The measures are highly correlated but occasionally inconsistent. We anticipate that health researchers and other scientists would be helped by summary indexes of birth weight and gestational age that give more precise indications...

The ranking had altered with utilization more number IPCA’s AMMI WAASB measures. Environments contributed about 53%, accounted for 30.5% Genot...

pollution sources into the water, the necessity of qualitative studies of water resources is one of the most important new challenges for mankind in almost every parts of the world. dissolved oxygen (do) and biochemical oxygen demand (bod) are among parameters of water quality indexes which are considered as water pollution indexes. in the present research, do and bod of dez river basin water (...

background and objectives: painting workshops are part of the woodwork (carpentry) industry in which despite advances in technology, the work force fulfills most of the roles in the production process. since such manual activities are often performed with awkward postures due to lack of workers’ awareness and inappropriate design of tools and working conditions, ergonomic assessment of work env...

BACKGROUND A number of indexes measuring self-reported generic health-related quality-of-life (HRQoL) using preference-weighted scoring are used widely in population surveys and clinical studies in the United States. OBJECTIVE To obtain age-by-gender norms for older adults on 6 generic HRQoL indexes in a cross-sectional US population survey and compare age-related trends in HRQoL. METHODS T...
