Background:
Questionnaires for estimating physical activity are measurement tools widely used by health professionals. Therefore, it is important to know their characteristics and quality. This systematic review aimed at identifying and analyzing de psychometric properties of the existing physical activity questionnaires validated in Spanish people older than 60 years of age, as well as to inform about the methodological quality of the studies performed concerning their validity and/or reliability.
Methods:
A systematic review of the available scientific literature regarding studies focused on the validity and/or reliability of questionnaires used for estimating the prevalence of physical activity among Spanish populations over 60 years old. The Qualitative Attributes and Measurement Properties of Physical Activity Questionnaires checklist (QAPAQ), was used to evaluate the sample characteristics, the psychometric properties, the validity, the test-retest reliability and the methodological quality of each study identified.
Results:
A total of 8 questionnaires were found and analyzed, highlighting in means of validity the short Spanish version (VREM) of the Minnesota Leisure Time Physical Activity Questionnaire (construct validity 95.5% with Kappa = 0.93) as well as in reliability (ICC=0.96), along with the Modified Baecke (ICC = 0,92-0,96). Four questionnaires met more than 80% of the criteria proposed by the QAPAQ. The YPAS was the questionnaire which reached the higher score.
Conclusions:
When estimating the amount of physical activity performed by Spanish people older than 60 years of age by means of questionnaires, it is advisable to use (in this order) the YPAS, VREM and Modified Baecke.

02:19Physical Properties Affecting Solubility
As for any solution, the solubility of a gas in a liquid is affected by the attractive intermolecular forces between solute and solvent species. Unlike solid and liquid solutes, however, there is no solute-solute intermolecular attraction to overcome when a gaseous solute dissolves in a liquid solvent since the atoms or molecules comprising a gas are far separated and experience negligible interactions. Consequently, solute-solvent interactions are the sole...

02:17Physical Properties of Ethers
An ether molecule has a net dipole moment due to the polarity of C–O bonds. Subsequently, boiling points of ethers are lower than those of alcohols of comparable molecular weight and slightly higher than those of hydrocarbons of comparable molecular weight (Table 1).
Ethers can act as hydrogen bond acceptors, making them more water-soluble than hydrocarbons, but since ethers cannot act as hydrogen bond donors, they are much less soluble in water than alcohols. Ethers are considered...
