Cross-laminated timber (CLT) is made up of multilayered timber stacked perpendicularly, which improved the dimensional stability and allowing CLT to has high bearing capacity in its two direction. Despite all the advantages, CLT has not yet gain much attention in Indonesian, especially the utilization in mid-rise building construction. In order to have a better understanding about CLT as main structural element, the behaviour of mid-rise building made of CLT was assessed by running a 3D model of 5-story building by combining building code in Indonesia with CLT parameter from previous researcher as well as recommended adjustment from previous researchers. The research shows that CLT building statisy the allowable parameter for mid-rise building in Indonesia.

ResumenLa fachada autoportante de ladrillo cara vista es el resultado de una profunda reflexión sobre las diferentes soluciones de fachada de ladrillo que se han utilizado a lo largo de la historia. Ha sido promovida por Hispalyt en estrecha colaboración con el Departamento Técnico de Geohidrol S.A., empresa líder en la investigación, fabricación y comercialización de sistemas para cerramientos de fábrica. Cuando se analizan las diferentes soluciones de las fachadas de ladrillo, bajo la óptica de los requisitos del Código Técnico de la Edificación, la fachada autoportante 'STRUCTURA' se manifiesta como la solución óptima por su simplicidad, sus elevadas prestaciones y el bajo coste en recursos auxiliares. La fachada autoportante 'STRUCTURA' se caracteriza porque la hoja exterior del cerramiento se construye totalmente separada del edificio, gravitando sobre sí misma, lo cual permite la disposición de una cámara de aire (ventilada o no) con aislamiento térmico continuo. De esta forma se elimina el puente térmico en el encuentro con los frentes de pilares y forjados, mejorando notablemente el rendimiento higrotérmico del edificio con el fin de cumplir el Documento Básico de Ahorro de Energía (DB HE), cuyos requisitos en la nueva versión aprobada en Septiembre de 2013 han experimentado un sustancial incremento respecto de los contenidos en la versión anterior. Desde el punto de vista de la respuesta mecánica, la fachada autoportante se fundamenta en el aprovechamiento del potencial que tienen los muros de ladrillo cuando se utilizan como soportes de sí mismos. A diferencia de las soluciones convencionales o de las que requieren elementos auxiliares de sostén dispuestos planta a planta, con la solución 'STRUCTURA' el muro de ladrillo se analiza como un elemento activo en el comportamiento estructural, de manera que su propio peso contribuye beneficiosamente en la resistencia frente a las acciones horizontales.AbstractThe self-supporting face brick façade is the result of a profound reflection on the different solutions for the brick façades that have been used throughout history. It has been promoted by Hispalyt in close collaboration with the Technical Department of Geohidrol S.A., leader company in the research, manufacture and marketing of systems for masonry closings. When analyzing different solutions of face brick façade, under the perspective of the technical building code requirements, the self-supporting façade 'STRUCTURA' appears as the optimal solution for its simplicity, high performance and low cost in auxiliary resources. The self-supporting façade 'STRUCTURA' is characterised by the outer leaf of the enclosure being built fully separately from the building, supported on itself, and thus enabling the provision of an air chamber (ventilated or not) with continuous thermal insulation. In this manner thermal bridges on the fronts of pillars and floors are eliminated, noticeably improving the hygrothermal performance of the building in order to comply with the technical building code basic document for energy saving (DB HE), whose requirements in the new version approved in September 2013 have substantially increased with respect to the requirements of the previous version. From the point of view of the mechanical response, the self-supporting façade is based on exploiting the potential that brick walls have when used as a load-bearing structural element themselves. Unlike conventional solutions or those that require additional support devices arranged floor-to-floor, with the 'STRUCTURA' solution the brick wall is analyzed as an active element in the structural behaviour, so that its own weight contributes beneficially to the resistance against horizontal actions.

The paper presents a microcomputer program designed for the evaluation of wind-induced forces, displacements, and accelerations of rectangular buildings in accordance with the stipulations and the methodology of the National Building Code of Canada. Meteorological data for Canadian cities have been included in a database file, so it is sufficient to provide information about the geometric, dynamic, and exposure characteristics of the building along with the name of the city of its location for a complete analysis by using either the detailed procedure or both the simple and detailed procedures. The program has been used in a parametric study to provide data of maximum displacements and accelerations of buildings. These data have been organized in charts useful to the professional engineer for preliminary design purposes. Key words: acceleration, building, code, design, displacement, pressure, wind, vibration.

Abstract Physicians who use the AMA Guides to the Evaluation of Permanent Impairment (AMA Guides) often serve as medical expert witnesses. In workers’ compensation cases, the expert may appear in front of a judge or hearing officer; in personal injury and other cases, the physician may testify by deposition or in court before a judge with or without a jury. This article discusses why medical expert witnesses are needed, what they do, and how they can help or hurt a case. Whether it is rendered by a judge or jury, the final opinions rely on laypersons’ understanding of medical issues. Medical expert testimony extracts from the intricacies of the medical literature those facts the trier of fact needs to understand; highlights the medical facts pertinent to decision making; and explains both these in terms that are understandable to a layperson, thereby enabling the judge or jury to render well-informed opinions. For expert witnesses, communication is everything, including nonverbal communication that critically determines if judges and, particularly, jurors believe a witness. To these ends, an expert medical witnesses should know the case; be objective; be a good teacher; state opinions clearly; testify with appropriate professional demeanor; communicate well, both verbally and nonverbally; in verbal communications, explain medical terms and procedures so listeners can understand the case; and avoid medical jargon, finding fault or blaming, becoming argumentative, or appearing arrogant.

Abstract. Chalcones are a type of flavonoids characterized by an α-β unsaturated structural element which may react with thiol groups to activate pathways such as the Nrf2-Keap-1 system. Naringenin chalcone is abundant in the diet but little is known about its bioavailability. In this work, the bioavailability of naringenin chalcone from tomatoes was investigated in a group of healthy men (n=10). After ingestion of 600 grams of tomatoes providing a single dose of 17.3 mg naringenin chalcone, 0.2 mg of naringenin, and 195 mg naringin plasma levels of free and conjugated naringenin and naringenin chalcone (glucuronide and sulfate) were analyzed by UHPLC-QTOF-MS at 0.5, 1, 3, and 6 h post-consumption. Plasma levels of conjugated naringenin increased to about 12 nmol/L with a maximum at about 3 h. Concentrations of free naringenin hardly elevated above baseline. Plasma levels of free and conjugated naringenin chalcone significantly increased. A maximum of the conjugated chalcone was reached at about 3 h after ingestion with an average concentration of about 0.5 nmol/L. No free chalcone was detectable at baseline but low amounts of the unconjugated compound could be detected with an average maximum of 0.8 nmol/L at about 1 h after ingestion. The data demonstrate that naringenin chalcone is bioavailable in humans from cherry tomatoes as a dietary source. However, availability is poor and intramolecular cyclisation as well as extended metabolism likely contribute to the inactivation of the reactive alpha-beta unsaturated reactive center as well as the excretion of the biologically active molecule, respectively.
