    Abstract Drinking water utilities rely on samples collected from the distribution system to provide assurance of water quality. If a water contamination incident is suspected, samples can be used to determine the source and extent of contamination. By determining the extent of contamination, the percentage of the population exposed to contamination, or areas of the system unaffected can be identified. Using water distribution system models for this purpose poses a challenge because significant uncertainty exists in the contamination scenarios (e.g., injection location, amount, duration, customer demands, contaminant characteristics). This article outlines an optimization framework to identify strategic sampling locations in water distribution systems. The framework seeks to identify the best sampling locations to quickly determine the extent of the contamination while considering uncertainty with respect to the contamination scenarios. The optimization formulations presented here solve for multiple optimal sampling locations simultaneously and efficiently, even for large systems with a large uncertainty space. These features are demonstrated in two case studies.

    Title translation Validación y adaptación transcultural de la escala Pedi-IKDC para la evaluación funcional de niños llevados a cirugía de rodilla.
    Abstract Introduction: In the last decades sports practice in children has increased, thus increasing the number of musculoskeletal injuries. There are no validated scales in Spanish for the functional evaluation of knee aspects in children. The validation and cross-cultural adaptation of the Pedi-IKDC scale to Spanish, used for this purpose, was carried out.
    Methodology: The scale was applied to 50 patients that suffered traumatic knee injuries between 2016 and 2021 and underwent surgical interventions. The validation process of the scale was carried out after a pilot test, cross-cultural adaptation of words into Spanish, translation-retranslation, statistical, determination of internal consistency of the instrument, intraclass correlation, test-retest and evaluation of data dispersion.
    Results: The internal consistency of the evaluated instrument is good according to the Gregory scale with a Cronbach's alpha of 0.82 The intraclass correlation was considered substantial (0.624) and the test-retest correlation, showed a coefficient of 0.91. The Bland-Altman graph showed a low dispersion among the data.
    Conclusion: The Pedi-IKDC scale can be a useful tool to assess functionality in children who have undergone knee surgery, it is considered valid, with adequate reliability and with the advantage of easy application.

    Abstract Due to the large coal fly ash (FA) production and its obvious environmental impact, alternative uses of this by-product must be researched. A considerable effort is being made worldwide on research concerning the reuse of FA as a source of alternative raw materials to produce new binder materials. One of the most promising building materials are geopolymers or alkali-activated materials (AAM). In this study, FA (25–75 wt %) was used to evaluate the potential of using this waste as a source of aluminosilicates for the synthesis of geopolymers to replace metakaolin (MK) as precursor. MK and FA geopolymers were also synthesized as a control. Sodium hydroxide and sodium silicate were used as alkaline-activator mix (Na₂SiO₃/NaOH ratio: 0.92). The geopolymers synthesized were characterized by Fourier Transform Infrared Spectroscopy (FTIR) X-ray diffraction (XRD) and Scanning Electron Microscopy-Energy Dispersive X-ray spectroscopy (SEM-EDS). The results indicate that control geopolymers, MK and FA geopolymers have similar mechanical and thermal properties. However, the MK-FA blended geopolymers have slightly lower compressive strengths and lower thermal conductivity. The decrease in the properties of the FA and MK-FA blended geopolymers may be due to the high solid/liquid ratio used, since the spherical particles of the FA require less liquid due to their higher workability. However, the obtained geopolymers can be a satisfactory solution for the recovery of waste that results in sustainable construction materials that meet the standard to be used for loadbearing concrete masonry units with insulating properties superior to Portland cement approaching the principles of circular economy.

    Title translation Factores de riesgo asociados al desarrollo de úlceras por presión en unidades de cuidados intensivos de adultos: revisión sistemática.
    Abstract Introduction: Pressure ulcers represent a significant problem for patients, professionals and health systems. Their reported incidence and prevalence are significant worldwide. Their character iatrogenic states that its appearance is preventable and its incidence is an indicator of scientific and technical quality both in primary care and specialized care. The aim of this review was to identify risk factors associated with the occurrence of pressure ulcers in critically ill patients.
    Methodology: The PRISMA Declaration recommendations have been followed and adapted to studies identifying risk factors. A qualitative systematic review of primary studies has been performed and a search was conducted of the PubMed, The Cochrane Library, Scopus and Web of Science databases. Methodological limitations in observational studies have been considered.
    Results: From 200 references, 17 fulfilled the eligibility criteria. These studies included 19,363 patients admitted to intensive care units. Six studies were classified as high quality and 11 were classified as moderate quality. Risk factors that emerged as predictive of pressure ulcers development more frequently included age, length of ICU stay, diabetes, time of MAP <60-70mmHg, mechanical ventilation, length of mechanical ventilation, intermittent haemodialysis or continuous veno-venous haemofiltration therapy, vasopressor support, sedation and turning.
    Conclusions: There is no single factors which can explain the occurrence of pressure ulcers. Rather, it is an interplay of factors that increase the probability of its development.

    Abstract Sixty occurrences of uterine torsion during late gestation in alpacas (n=56) and llamas (n=4) were evaluated to identify the relationship of direction and degree of severity of torsion, method of correction, and dam and cria survival. Other recorded data included the time to presentation, stage of gestation, parity, and clinicopathologic assessment. Three treatment groups were identified: animals which had uterine torsion corrected by rolling only (60%; n=36); animals which underwent Cesarean section only (23.3%; n=14); and animals which first were rolled but then underwent Cesarean section (16.7%; n=10). Significant relationships were recorded between the degree of uterine torsion and the method of correction – 360° torsions were more likely to have to undergo Cesarean section, either as a solitary treatment method or after rolling (p<0.05). No significant relationship was recorded between the gestation age of the fetus and the treatment method implemented. Counter-clockwise torsions accounted for 18.3% of the cases. Survival of females was high (96.7%; n=60), regardless of the treatment method. Survival of the cria was lower for torsions corrected by Cesarean section alone (71.4%; n=14) or after rolling (70%; n=10), when compared to rolling only (100%; n=36). The most common clinicopathological findings were toxemia alone or with concurrent hypocalcemia or hepatic lipidosis, and elevated creatine kinase. All cases of toxemia had hyperglycemia and tended to have a prolonged interval to presentation.

    Title translation Adaptation and validation of five scales to measure determinants of binge drinking in adolescents.
    Abstract Background: The aim of this study was to validate five scales, based on a theoretical framework for the adoption of behaviours, designed to assess the determinants in binge drinking in adolescents, namely: attitude, social influence (model, norm and pressure) and self-efficacy.
    Methods: Observational, cross-sectional and multicentre study. Through convenience sampling, 397 adolescents between 15 to 18 years old enrolled in secondary schools in Seville and Huelva were included. After translation and review of the original instrument by a panel of experts, a questionnaire was obtained in Spanish that was administered to a pilot sample to assess comprehensibility and, subsequently, the participants completed the five scales to check the structural validity (factor analysis and reliability) and construct validity.
    Results: On the five scales, the first factor explained at least 28% of the variance and the total variance explained was always greater than 60%. After rotation, all items had weights >0.40 for the factor to which they belonged. Cronbach´s alpha ranged from 0.62 to 0.91. Spearman's coefficient was lower than 0.7 when correlating the sub-dimensions of the scales, except on the self-efficacy scale, assuming multidimensionality with certain limitations.
    Conclusions: Five scales are presented with indications of reliability and validity, their items reflect the theoretical frame of reference and can evaluate the determinants of binge drinking. In the future, validation could be continued to determine its reproducibility, its criterion validity with a "gold standard" or objective measure. Key words. Adolescents. Health behaviour. Binge drinking.
    Risk factors: Validation studies.

    Abstract Objective: Contribution to validation of the Braden scale in patients admitted to the ICU, based on an analysis of its reliability and predictive validity.
    Design: An analytical, observational, longitudinal prospective study was carried out.
    Setting: Intensive Care Unit, Hospital Virgen del Rocío, Seville (Spain).
    Patients: Patients aged 18years or older and admitted for over 24hours to the ICU were included. Patients with pressure ulcers upon admission were excluded. A total of 335 patients were enrolled in two study periods of one month each.
    Interventions: None.
    Variables of interest: The presence of gradei-iv pressure ulcers was regarded as the main or dependent variable. Three categories were considered (demographic, clinical and prognostic) for the remaining variables.
    Results: The incidence of patients who developed pressure ulcers was 8.1%. The proportion of gradei andii pressure ulcer was 40.6% and 59.4% respectively, highlighting the sacrum as the most frequently affected location. Cronbach's alpha coefficient in the assessments considered indicated good to moderate reliability. In the three evaluations made, a cutoff point of 12 was presented as optimal in the assessment of the first and second days of admission. In relation to the assessment of the day with minimum score, the optimal cutoff point was 10.
    Conclusions: The Braden scale shows insufficient predictive validity and poor precision for cutoff points of both 18 and 16, which are those accepted in the different clinical scenarios.

    Title translation Design and validation of scales to measure adolescent attitudes toward sexuality, addictive substances and road safety. Are they related to behaviour?.
    Abstract Background: To validate scales to measure adolescent attitudes toward sexuality (EAS), toward addictive substances (EASA) and toward vial security (EASV), and to examine their correlations with behaviour on these areas.
    Methods: We designed the scales by literature review; we validated their content using a Delphi-on-line panel with 18 experts, and a pre-test with a sample of 21 fourth-grade high-school students (similar to 10th in US) in Seville, Spain. The scales were administered to 188 fourth-grade high-school students in order to test their construct validity (exploratory factor analysis), their reliability (Alpha Cronbach test), and to determinate their correlations with age, gender, experience of sexual intercourse, substance use and road behaviour.
    Results: EAS-10 obtained α=0.73, EASA-12 obtained α=0.80, EASV-12 obtained α=0.79. They showed evidence of one-dimensional interpretation after factor analysis, a) all items achieved weights r>0.30 in the first factor, which explained a significant proportion of variance before rotations, and b) total variance explained by the main factors extracted was greater than 50%. We found correlations between EASA-12 and tobacco use (r=-0.43, p<0.001), alcohol use (r=-0.30, p<0.001), age of alcohol initiation (r=0.32, p=0.003), and substance use (r=-0.55, p<0.001), and between EASV-12 and safe road behaviour (r=0.41, p<0.001), tobacco use (r=-0.23, p=0.003), alcohol use (r=-0,22, p=0,003), age of first experience of drunkenness (r=0.22, p=0.003), and substance use (r=-0.27, p=0.013).
    Conclusions: The scales showed their reliability and validity. They could be employed for assessing adolescent attitudes to these priority intervention areas, for carrying out studies on their mediating role on adopting behaviour, and for designing and evaluating health programs.
