Intermittent water supply systems are prone to air entrapments during the pipe-filling phase. This work aims to analyse and discuss the numerical results obtained by applying the recently developed AirSWMM model, an extension of SWMM incorporating air phase, to a laboratory network. Experimental data consisting of pressure-head at multiple locations and video recordings of air entrapments are collected in a single loop network with a high point, for different pipe-filling conditions, system layouts and node elevations. Experimental tests have shown that the air entrapment occurred not only at the high point but also throughout the pipe network, creating air pockets with elongated shapes and larger volumes than for single pipes. AirSWWM model with air-entrapment formation, growth and transport is tested inthe pipe network, and results are compared with measurements. AirSWWM model can correctly locate large air pockets but underestimates their volume.

This research provides a first assessment of the location of air pockets in a case study from the literature by using the developed AirSWMM. A pressure-driven analysis is implemented in the source code of AirSWMM(v2.0) to better simulate the nodal demand since this feature was not originally included in SWMM. Pressure-head results for different spatial discretisations are compared with collected field data to assess the best compromise between spatial discretisation and the results’ accuracy. The recommendations from international guidelines for the location of air release devices are compared to the predicted air pocket locations to assess if the numerical estimates are in agreement with the empirical evidence.

Drawings for the fabrication and assembly of a module for a 1.5 meter long, 0.5 meter wide and 1.0 meter low-cost wave flume. In addition, the BIM model of the channel is provided for use in Autodesk Revit or another BIM program. Furthermore, in this version (2.0), the files needed to manufacture and commission the wave generator and an Excel file to perform the design and structural checks have been added.

Average concentrations of benzene, NO2 and O3 in the air in Cartagena (Murcia, Spain) from 15 to 22 July 2009. Units are ug/m3.

This dataset presents a collection of environmental measurements taken by the s-Nautilus profiler at "La Isleta" yacht club in the Mar Menor. The recorded variables include: -Time (yyyy-mm-dd hh:mm:ss): The timestamp indicating the date and time of each measurement. -Depth (m): The depth at which the measurements were taken. -Dissolved Oxygen (DO) : The concentration of dissolved oxygen, essential for assessing water quality and the health of the marine ecosystem. -Electrical Conductivity (EC): A parameter indicating the ability of the water to conduct electricity, directly related to salinity and the presence of ions. -Temperature (T) (ºC): The water temperature, a critical factor influencing many chemical and biological processes. -Battery Voltage (Batt3): The voltage of the batteries powering the electronics of the profiler, providing insight into its autonomy. Measurements were taken every 6 hours during the ascent of the profiler.

These datasets may include EEG and ECG data in response to auditory and visual stimuli, as well as different stimulus animation speeds, which could be useful for your research or project. This dataset have record 5 minutes and separate with 0.6 seconds.

This document contains the template used for the survey "Analysis of the gender gap in Engineering and Architecture studies" and the summary of responses. Data collection was carried out through an online survey using a Google form. The form was open from Monday, October 23, 2023 to Monday, November 20, 2023.

The purpose of the present study was to examine the effect of KT on 30 m sprint and counter movement jump performance in active children. Methods. A randomized crossover, pretest/posttest repeated measures design was used to compare the effects of KT on triceps surae and no taping. To generate the random assignment sequence, the data collection sheets were randomly marked with a small letter a or b alternatively. Only the KT practitioner knew that these letters corresponded to one of the two groups. The two sessions were separated for three days to avoid accumulation of the KT effects and took place on the same public sports track. Of the 28 healthy active children (12 girls and 16 boys) enrolled in a triathlon school, all children voluntarily participated in the present study. Results. The results of the ANOVA on the average obtained in the counter movement jump test showed differences statistical significant a favor of KT condition [F(1, 19) = 12.383, p = 0.002; η2 = 0.395; P = 0.916]. However, the ANOVA results on the average obtained in the sprint test did not show differences statistical significant in 0-15 m, 15-30 m, and 0-30 m. Conclusions. KT on the triceps surae does not seem to affect the sprint performance in apparently healthy active children, but it does on the counter movement jump test. The KT application did not cause any discomfort or injury to the children during the study.
