Voice Quality of Life and Musculoskeletal Symptoms of Pregnant Women.

Introduction: Quality of life in terms of voice and musculoskeletal symptoms can be affected, especially at the end of pregnancy when major physical changes occur.

Objective: To analyze the results of vocal self-assessment and musculoskeletal symptoms of pregnant women in the second and third trimester.

Methods: Forty-nine pregnant women in the second and third trimester aged between 18 and 40years were examined using the Nordic Musculoskeletal Questionnaire and the Voice-Related Quality of Life Questionnaire.

Optimization of Pin Position and Angle for Z-Pin-Reinforced Foam Core Sandwich Structures.

Sandwich panels (SP) are very promising components for structures as they ally high levels of specific stiffness and strength. Civil, marine and automotive industries are some examples of the sectors that use SPs frequently. This work demonstrates the potential of manufacturing Z-pin-reinforced foam core SPs, using a design strategy that indicated optimal values for both pin position and angle, keeping the same pin diameter as determined in a previous study.

Aerodynamic and Manovacuometric Vocal Measurements in Pregnant Women in the Second and Third Trimesters of Pregnancy.

Objective: To describe and to correlate the aerodynamic and manovacuometric voice measurements of pregnant women.

Methods: The following evaluations were carried out on 49 pregnant women - between 18 and 40 years old - in the second and third trimesters of gestational age: respiratory muscle strength, maximum phonation time of /a/, habitual, minimum, and maximum sound pressure levels. The data were statistically described and tested for the hypothesis of no association between voice measurements and refence levels, and for the correlation between voice measurements.

A distance to the Large Magellanic Cloud that is precise to one per cent.

In the era of precision cosmology, it is essential to determine the Hubble constant empirically with an accuracy of one per cent or better. At present, the uncertainty on this constant is dominated by the uncertainty in the calibration of the Cepheid period-luminosity relationship (also known as the Leavitt law). The Large Magellanic Cloud has traditionally served as the best galaxy with which to calibrate Cepheid period-luminosity relations, and as a result has become the best anchor point for the cosmic distance scale.
