Dust events characterization from visibility, trends and Dust Adversity Index in the Canary Islands for the period 1980-2022.

Dust events in the Canary Islands have been documented since the late 19th century. However, during the past few years, several severe dust episodes have occurred in the Canary Islands, resulting in significant impacts on various sectors, such as aviation, air quality, and health, among others. These recent severe events have drawn the attention of both scientists and the general population, raising questions about whether these episodes are now more frequent and more severe.

Long-Term Analysis of Aerosol Concentrations Using a Low-Cost Sensor: Monitoring African Dust Outbreaks in a Suburban Environment in the Canary Islands.

This study presents the results of the long-term monitoring of PM10 and PM2.5 concentrations using a low-cost particle sensor installed in a suburban environment in the Canary Islands. A laser-scattering Nova Fitness SDS011 sensor was operated continuously for approximately three and a half years, which is longer than most other studies using this type of sensor.

Impact of exposure of emergency patients with acute heart failure to atmospheric Saharan desert dust.

Objectives: To explore whether episodes of exposure to atmospheric Saharan dust is a risk factor for hospitalization in patients with acute heart failure (AHF) attended in a hospital emergency department (ED).

Methods: Single-center retrospective study of patients with AHF. The cohort was analyzed in 2 groups: ED patients hospitalized with AHF and patients discharged home from the ED.

Arrival of radionuclides released by the Fukushima accident to Tenerife (Canary Islands).

Two weeks after the accident at the Fukushima-Daichi nuclear power plant, 131I, 137Cs and 134Cs activities were measured in two different stations located in Tenerife (Canary Islands), situated at 300 (FIMERALL) and 2400 (IZAÑA) m.a.s.

Source areas and long-range transport of pollen from continental land to Tenerife (Canary Islands).

The Canary Islands, due to their geographical position, constitute an adequate site for the study of long-range pollen transport from the surrounding land masses. In this study, we analyzed airborne pollen counts at two sites: Santa Cruz de Tenerife (SCO), at sea level corresponding to the marine boundary layer (MBL), and Izaña at 2,367 m.a.

[Magnetic materials in dentistry].

In the last 40 years, magnets have been used in dentistry. Initially as anecdotic reports, but recently, after the development of powerful rare earth magnets, new applications of them have arised and offer a clinically proved alternative to mechanical systems. Many experimental and clinical trials have demonstrated their adequate use in prosthetic rehabilitations, partial removable or overdentures, tooth or implant beared, or in other like orthodontics.

[Achalasia of the cricopharyngeal muscle in the infant].

Two patients with Cricopharyngeal achalasia have been treated at the Clínica Infantil "La Paz" (Madrid) in the last 20 years. They were one and a half, and four and a half months old at the time of operation. The postoperative period and follow-up has been satisfactory.
