[Cr(dmbipy)(ox)2]−: a new bis-oxalato building block for metal assembling. Crystal structures and magnetic properties of XPh4[Cr(dmbipy)(ox)2]·5H2O (X = P and As), {Ba(H2O)2[Cr(dmbipy)(ox)2]2}n·17/2nH2O and {Ag(H2O)[Cr(dmbipy)(ox)2]}n·3nH2O

The synthesis, X-ray structure and variable-temperature magnetic study of new compounds of formula PPh4 [Cr(dmbipy)(ox)2 ]$5H2O (1), AsPh4 [Cr(dmbipy)(ox)2 ]$5H2O (2), {Ba(H2O)2[Cr(dmbipy)(ox)2]2}n$17/2nH2O (3) and {Ag(H2O)[Cr(dmbipy)(ox)2]}n$3nH2O (4) (PPh4 + ¼ tetraphenylphosphonium cation; AsPh4 + ¼ tetraphenylarsonium cation; dmbipy ¼ 4,4 0 -dimethyl- 2,2 0 -bipyridine; ox 2 ¼ oxalate dianion) are reported herein. The isomorphous compounds 1 and 2 are made up of discrete [Cr(dmbipy)(ox)2] anions, XPh4 + cations [X ¼ P (1) and As (2)] and uncoordinated water molecules. The chromium environment in 1 and 2 is distorted octahedral with Cr–O and Cr–N bond distances varying in the ranges 1.950(2)–1.9782(12) and 2.047(3)–2.0567(14) A˚ , respectively. The angles subtended at the chromium atom by the two bidentate oxalate ligands cover the range 82.58(10)– 83.11(5) , and they are somewhat greater than those concerning the chelating dmbipy [79.04(10) (1) and 79.24(5) (2)]. The [Cr(dmbipy)(ox)2] unit of 1 and 2 also occurs in 3 and 4 but it adopts different coordination modes. It acts as a chelating ligand through its two oxalate groups towards the divalent barium cations in 3 affording neutral chains with diamond-shaped units sharing the barium atoms, while the two other corners are occupied by two crystallographically independent chromium atoms. The barium atom in 3 is coordinated by eight oxygen atoms from four oxalate groups and two aqua ligands. The structure of 4 consists of neutral bimetallic layers where the [Cr(dmbipy)(ox)2] unit acts as a ligand towards the univalent silver(I) cation through its two oxalate groups, one of them being bidentate and the other bidentate/monodentate (outer). Each silver atom is six-coordinated with a water molecule and five oxygen atoms from three oxalate groups building a highly distorted octahedral environment. Magnetic susceptibility measurements for 1–4 in the temperature range 1.9– 300 K show the occurrence of weak ferro- (1 and 2) and antiferromagnetic (3 and 4) interactions which are mediated by p–p stacking between dmbipy ligands through the spin polarization mechanism. A comparative study of the potentiality of the [Cr(AA)(ox)2] unit (AA ¼ bidentate nitrogen donor) as a building bl

Internet Addiction, Phubbing, Psychological Variables and Self-Perception of Mathematical Competence in College Students

Internet Addiction (IA) and phubbing are prevalent, disruptive behaviours among university students. The aim of this study was to explore the relationship between IA and Phubbing with psychological variables (impulsiveness, self-esteem, and psychological distress), academic performance and self-perception of mathematical competence (SMC), as well as possible gender differences. Results showed (n = 715; Mean Age = 21.7) gender differences in lack of planning, emotional investment and somatisation and IA correlated positively with app addiction, mobile addiction, and psychopathology. A total of 26.3% of IA can be explained by a lack of self-control, time and performance management, mobile phone addiction, anxiety and psychological distress. Finally, 71% of students believe that the use of new technologies has worsened their SMC and this is correlated with impaired communication, obsession with mobile phones, IA (Total Phubbing Scale) and impulsiveness. Our results indicate the importance of taking into account psychological variables that affect the development of IA, phubbing, and SMC in the university population

Incidence of peripheral arterial disease in the ARTPER population cohort after 5 years of follow-up

To know the epidemiology (prevalence, incidence, progression and morbidity and mortality associated) of peripheral artery disease in general population and the factors associated with this progression is essential to know the evolution of atherosclerosis and develop preventive strategies. The aim of the study was to determine the incidence of PAD after 5 years of follow-up population-based cohort ARTPER, and the evolution of Ankle brachial Index (ABI) in this period. Peripheral artery disease incidence analysis after 5 years of follow-up of 3786 subjects > 50 years old. Peripheral artery disease incident when the second cross section Ankle brachial Index was <0.9 in any of the lower limbs, with normal baseline (0.9 to 1.4). Between 2012 and 2013 2762 individuals (77 % participation) were re-examined. Finally analyzed 2256 subjects (after excluding pathological Ankle brachial Index) followed for 4.9 years (range 3.8 to 5.8 years), totalling 11,106 person-years. Peripheral artery disease 95 new cases were detected, representing an incidence of 4.3 % at 5 years and 8.6 per 1000 person-years (95 % CI 6.9 to 10.5) being higher in men (10.2, 95 % CI 7.4 to 13.5) than in women (7.5, 95 % CI 5.5 to 9.9). Linear correlation between the baseline Ankle brachial Index and the second cross section was low (r = 0.23). The incidence of peripheral artery disease in ARTPER cohort was 8.6 cases per 1000 person-years, being higher in men, especially <65 years. The correlation between two measures Ankle brachial Index after 5 years of follow-up was low. One might consider whether Ankle brachial Index repeated measures could improve the correlation

Transmitancia térmica de la envolvente y cumplimiento del DB-HE 2019 para un bloque de viviendas

This article shows a work about the compliance of the new DB-HE sections, HE0 and HE1, and the economic cost of the thermal envelope for a residential multi-family block. It was studied among diverse window-wall ratios and there were examined the necessary solutions for the different Spanish climates, aiming to find out how to verify the requirements of demand control and the limits of consumes incorporated in the last actualization of the DB-HE, through economic optimization criteria on a simplified cost model basis.Este artículo analiza el cumplimiento normativo de las secciones HE0 y HE1 del reciente DB-HE 2019 y el coste económico de la envolvente térmica para un edificio de uso residencial plurifamiliar entre medianerías. Se ha estudiado este modelo con distintos porcentajes de huecos y se han examinado las soluciones necesarias para los diferentes climas de la geografía española, con el objetivo de encontrar estrategias para la verificación de los requisitos de control de la demanda y límite de los consumos incorporados en la última actualización del DB-HE, a través de criterios de optimización económica en base a un modelo de costes simplificado

Psicosis y diferencias sociales: Comparando la prevalencia de las psicosis en dos medios urbanos diferenciados.

Objetivos: Contribuir a la reflexión sobre la etiología y/o los factores de riesgo para las psicosis comparando la prevalencia en población general y población de riesgo de la esquizofrenia y otras psicosis en dos barrios de Barcelona (España). Método: Nuestras aportaciones en este trabajo se apoyan sobre todo en un estudio descriptivo transversal de todos los pacientes con psicopatología detectados en la USM de Sant Martí-La Mina: un territorio geodemográfica y asistencialmente delimitado formado por 5 Áreas Básicas de Salud (103.615 habitantes. Resultados: Sobre un total de 21.536 pacientes con registro de casos abierto desde el año 1982 hasta el año 2000, se halló que 838 cumplían los criterios restrictivos para ser diagnosticados como “esquizofrénicos” (N=476) o “afectados por otras psicosis” (N=362). Sin embargo, las prevalencias de esquizofrenia y otras psicosis en el barrio sujeto a más factores de riesgo psicosociales eran alrededor de 2 veces mayores que las encontradas en el barrio colindante por el mismo equipo y en el mismo período temporal. Conclusión: Es necesario tener en cuenta el gran peso de los factores de sociales y psicosociales para poderse explicar las diferencias de prevalencia de la esquizofrenia y otras psicosis entre diferentes poblaciones

Ischemic stroke incidence in Santa Coloma de Gramenet (ISISCOG), Spain. A community-based study

<p>Abstract</p> <p>Background</p> <p>In Spain, stroke is one of the major causes of death and the main cause of severe disability in people over 65 years. We analyzed the incidence of ischemic stroke, stroke subtypes, case fatality and disability at 90 days after the event in a Spanish population.</p> <p>Methods</p> <p>A prospective community-based register of ischemic strokes was established in Santa Coloma de Gramenet (Barcelona) [116,220 inhabitants of all ages, according to the municipal census of December 31,2001], from January 1 to December 31, 2003.</p> <p>Standard definitions and case finding methods were used to identify all cases in all age groups. Every patient underwent a complete clinical evaluation and systematic tests including neuroimaging (CT/MRI) and vascular studies (carotid duplex ultrasound intra and extracranial and MR angiography).</p> <p>Results</p> <p>Over a one year period, 196 ischemic strokes were registered [107 men; median age = 76 years (range 39–98)], being the first event in 159 patients (81.1%) and a recurrent stroke in 37 (18.9%). After age-adjustment to the European population, the incidence of ischemic stroke per 100,000 inhabitants was 172 (95% CI, 148–196); 219 (176–261) in men and 133 (105–160) in women, with an annual incidence for first ischemic stroke of 139 (118–161); 165 (128–201) in men and 115 (89–140) in women. The incidence of stroke increased with age.</p> <p>Stroke subtypes (TOAST classification criteria) were lacunar in 28.8%, atherothrombotic in 18.6%, cardioembolic in 26.6% and undetermined in 26.0% of patients. At 90 days, the case-fatality was 12%, and among survivors, moderate-to-severe disability was present in 45 % at 3 months.</p> <p>Conclusion</p> <p>This prospective community-based study shows one of the lowest incidences of stroke in Europe, as well as one of the lowest case fatality and disability rates at 90 days after stroke.</p
