Regiomontan: A Regional High Precision Ionosphere Delay Model and Its Application in Precise Point Positioning.

Propagation delays of GNSS signals caused by the ionosphere can range up to several meters in zenith direction and need to be corrected. Geodetic receivers observing at two or more frequencies allow the mitigation of the ionospheric effects by forming linear combinations. However, single frequency users depend on external information.

[Low agreement between the fitnessgram criterion references for adolescents].

Objective:: To analyze the association and agreement of reference criteria (RC) for cardiorespiratory fitness, body mass index (BMI) and strength in youth.

Methods:: The study included 781 youth, 386 females, aged 10 to 18 years of Londrina-PR. It were performed cardiorespiratory fitness and muscular strength tests and was calculated body mass index.

[Reasons and prevalence of body image dissatisfaction in adolescents].

Objective: To investigate the prevalence of body image (BI) dissatisfaction in adolescents. The study enrolled 641 adolescents aged 11 to 17 from the town of Saudades, Santa Catarina, Brazil. The prevalence of BI dissatisfaction was 60.

[Metabolic syndrome prevalence in males].

Objective: Determining metabolic syndrome (MS) prevalence amongst employees from a steel company in Distrito Federal according to age and ethnic-racial classification, comparing biochemical, anthropometric and hemodynamic indicators according to MS presence or absence.

Methods: A total of 125 men (aged 20-69) participated in the study. Data was collected regarding age, ethnic origin, body weight, height, body mass index (BMI), waist circumference, glucose, triglycerides, total cholesterol, high-density lipoprotein (HDL-c), systolic (SBP) and diastolic blood pressure (DBP).

Validation of a new cycle ergometer.

The purpose of this study was to test the concurrent validity of the ICBE compared to the Monark(®) cycle ergometer by indirect dynamic calibration. 42 men were randomly submitted to 2 maximal stress tests with increments of 50 W at 2-min intervals. One test was performed on the Monark(®) bicycle (834/E) and the other on the ICBE.
