Estudio de la evolución de la velocidad de ultrasonidos en probetas de hormigón con distintos grados de humedad

El hormigón es uno de los materiales más utilizados en el mundo de la construcción y la ingeniería a lo largo de la Historia. El comportamiento y las propiedades de este material a lo largo del tiempo son objeto de numerosos estudios debido a las características monolíticas y mecánicas que presenta y a la abundancia de sus componentes en la naturaleza. [1] Se ha realizado un estudio experimental sobre probetas cúbicas de hormigón en masa (dimensiones: 10x10x10 cm) de la evolución de la velocidad de propagación de ultrasonidos (US) a través del hormigón y el grado en que afectan distintas variables a dicha velocidad, y su posible relación con su resistencia a compresión. Se han fabricado 32 probetas con hormigón H-25, tomando dos dosificaciones diferentes en cuanto a la relación agua/cemento (A/C) (A/C=0,5 y A/C=0,6), y empleando dos tipos distintos de árido grueso. Sobre dichas probetas se han llevado a cabo medidas periódicas de velocidad de propagación de US y del grado de humedad que adquieren durante el tiempo de curado en cámara húmeda y durante su endurecimiento en ambiente de laboratorio hasta su rotura a compresión. También se las sometió a ensayos de rotura a compresión con el fin de determinar posibles dependencias entre la resistencia a rotura adquirida y la máxima deformación experimentada con dicha velocidad de propagación y contenido de humedad. [2] [3] Una vez realizados los ensayos, se puede observar un comportamiento respecto a la velocidad de propagación a través del hormigón. El ambiente al que se expone el hormigón es determinante a la hora de establecer correlaciones entre la velocidad y el contenido de humedad. En cuanto a la fase de ensayos destructivos, se observa una evolución frente a esfuerzos de compresión similar, presentando una resistencia y un límite elástico un 16% aproximadamente superior en el hormigón con menor cantidad de humedad (relación A/C=0,5).

Up-regulation Of Dnam-1 And Nkp30, Associated With Improvement Of Nk Cells Activation After Long-term Culture Of Mononuclear Cells From Patients With Ovarian Neoplasia.

This study aimed at evaluating the functional activation and activating receptors expression on resting, short- and long-term NK and NK-like T cells from blood of ovarian neoplasia patients. Blood from patients with adnexal benign alterations (n = 10) and ovarian cancer (grade I-IV n = 14) were collected after signed consent. Effector cells activation was evaluated by the expression of the CD107a molecule. Short-term culture was conducted overnight with IL-2 and long-term culture for 21 days, by a method designed to expand CD56(+) lymphocytes. Short-term culture significantly increased NK cells activation compared to resting NK cells (p<0.05), however, the long-term procedure supported an even higher increase (p<0.001). Resting NK-like T cells showed poor activation, which was not altered by the culture procedures. The long-term culture effectively increased the expression of the activating receptors on NK and NK-like T cells, either by increasing the number of cells expressing a given receptor and/or by up-regulating their expression intensity. As a conclusion, the long-term culture system employed, resulted in a high number of functional NK cells. The culture system was particularly efficient on the up-regulation of NKp30 and DNAM-1 receptors on NK cells.

Hypertrophic Adenoid Is A Major Infection Site Of Human Bocavirus 1.

Human bocavirus 1 (HBoV1) is associated with respiratory infections worldwide, mainly in children. Similar to other parvoviruses, it is believed that HBoV1 can persist for long periods of time in humans, probably through maintaining concatemers of the virus single-stranded DNA genome in the nuclei of infected cells. Recently, HBoV-1 was detected in high rates in adenoid and palatine tonsils samples from patients with chronic adenotonsillar diseases, but nothing is known about the virus replication levels in those tissues. A 3-year prospective hospital-based study was conducted to detect and quantify HBoV1 DNA and mRNAs in samples of the adenoids (AD), palatine tonsils (PT), nasopharyngeal secretions (NPS), and peripheral blood (PB) from patients undergoing tonsillectomy for tonsillar hypertrophy or recurrent tonsillitis. HBoV1 was detected in 25.3% of the AD samples, while the rates of detection in the PT, NPS, and PB samples were 7.2%, 10.5%, and 1.7%, respectively. The viral loads were higher in AD samples, and 27.3% of the patients with HBoV had mRNA detectable in this tissue. High viral loads and detectable mRNA in the AD were associated with HBoV1 detection in the other sample sites. The adenoids are an important site of HBoV1 replication and persistence in children with tonsillar hypertrophy. The adenoids contain high HBoV1 loads and are frequently positive for HBoV mRNA, and this is associated with the detection of HBoV1 in secretions.
