Chlordetect: Commercial Calcium Aluminate Based Conductimetric Sensor for Chloride Presence Detection.

Chloride presence affects different environments (soil, water, concrete) decreasing their qualities. In order to assess chloride concentration this paper proposes a novel sensor for detecting and measuring it. This sensor is based on electric changes of commercial monocalcium aluminate (CA) when it interacts with chloride aqueous solutions. CA is used as a dielectric material between two coplanar capacitors. The geometry proposed for this sensor allows to assess the chloride content profile, or to make four times the same measurement. Besides, the experimental design gives us the possibility of study not just the chloride effect, but also the time and some geometric effects due to the sensor design. As a result, this sensor shows a limit of detection, sensitivity, and response time: 0.01 wt % Cl- and 0.06 wt % Cl-, and 2 min, respectively, comparable with other non invasive techniques as optical fibre sensors.

Climate change indicators dataset for coastal locations of the European Atlantic area.

Over time, considerable changes in the earth's climate have always occurred due to a wide variety of natural processes. During the last century, these natural changes have all been accelerated by global warming, which has been driven by human activities. Climate change leads to wide variations in environmental variables such as temperature, relative humidity, carbon dioxide, etc. These changes could adversely affect the performance, serviceability, and safety of infrastructure assets. The challenge, therefore, is to not only understand the effect of extreme events and their links to climate change, but also to obtain data that could be used for assessing long-term gradual effects affecting infrastructure assets. In this paper is presented a climate indicators database that was collected and provided in an excel format. This database could be used for assessing the durability, vulnerability, and cost-effectiveness of adaptation measures for coastal infrastructure assets. The database contains information for specific coastal locations placed in five European countries: Caxias (Portugal), Saint Nazaire (France), Vigo (Spain), Brighton (UK), Dublin and Cork (Ireland). The database includes atmospheric, and oceanic indicators, as well as and the flow of rivers. It covers a time series of up to 2100 with various representative concentration pathways and climate models.

A Genomic Snapshot of the SARS-CoV-2 Pandemic in the Balearic Islands.

Objective: To analyze the SARS-CoV-2 genomic epidemiology in the Balearic Islands, a unique setting in which the course of the pandemic has been influenced by a complex interplay between insularity, severe social restrictions and tourism travels. Methods: Since the onset of the pandemic, more than 2,700 SARS-CoV-2 positive respiratory samples have been randomly selected and sequenced in the Balearic Islands. Genetic diversity of circulating variants was assessed by lineage assignment of consensus whole genome sequences with PANGOLIN and investigation of additional spike mutations. Results: Consensus sequences were assigned to 46 different PANGO lineages and 75% of genomes were classified within a VOC, VUI, or VUM variant according to the WHO definitions. Highest genetic diversity was documented in the island of Majorca (42 different lineages detected). Globally, lineages B.1.1.7 and B.1.617.2/AY.X were identified as the 2 major lineages circulating in the Balearic Islands during the pandemic, distantly followed by lineages B.1.177/B.1.177.X. However, in Ibiza/Formentera lineage distribution was slightly different and lineage B.1.221 was the third most prevalent. Temporal distribution analysis showed that B.1 and B.1.5 lineages dominated the first epidemic wave, lineage B.1.177 dominated the second and third, and lineage B.1.617.2 the fourth. Of note, lineage B.1.1.7 became the most prevalent circulating lineage during first half of 2021; however, it was not associated with an increased in COVID-19 cases likely due to severe social restrictions and limited travels. Additional spike mutations were rarely documented with the exception of mutation S:Q613H which has been detected in several genomes (n = 25) since July 2021. Conclusion: Virus evolution, mainly driven by the acquisition and selection of spike substitutions conferring biological advantages, social restrictions, and size population are apparently key factors for explaining the epidemic patterns registered in the Balearic Islands.

Psychological the most common elder abuse in a Havana neighborhood.

INTRODUCTION: Globally, older adults are a population group that often suffers abuse by their caregivers. Along with women and children, they are among those most often reported as victims of abuse of any kind in Cuba. OBJECTIVE: Characterize presence of domestic abuse of older adults in family doctor-and-nurse office No. 28 of the Carlos Manuel Portuondo University Polyclinic in Havana, Cuba, determining the main manifestations of abuse and help-seeking behavior by the older adults identified as victims. METHOD: This was a descriptive cross-sectional study of adults aged ≥ 60 years; all those not diagnosed with dementia and who agreed to participate were interviewed. In a universe of 268 older adults, 29 were living outside the area, 24 declined to participate, and 18 had a diagnosis of dementia, leaving a study population of 197 individuals. Variables included: personal experience of abuse, type of abuse, perpetrator, help sought, and reasons for not seeking help. Statistical analysis was based on percentages. RESULTS: Of 197 older adults interviewed, 88 (44.7%) reported that they were victims of domestic abuse; 50 of these were women. The most common types of abuse were psychological abuse and disrespect for personal space, reported by 69 (78.4%) and 54 (61.4%) individuals, respectively. Sons- and daughters-in-law were identified as the abusers by 68 participants and grandchildren by 65. Of the 88 victims, 67 (76.1%) stated that they did not seek help. CONCLUSIONS: The finding that substantial numbers of older adults are victims of domestic abuse brings to light a hitherto insufficiently addressed issue in the community studied. More research is needed to deepen understanding of the scope and causes of the problem to inform prevention and management strategies, not only at the level of the polyclinic catchment area, but in the health system in general.
