Site Characterization of Bangalore using Geophysical Method

A number of geophysical methods have been proposed for near-surface site characterization and measurement of shear wave velocity by using a great variety of testing configurations, processing techniques,and inversion algorithms. In particular, two widely-used techniques are SASW (Spectral Analysis of SurfaceWaves) and MASW (Multichannel Analysis of SurfaceWaves). MASW is increasingly being applied to earthquake geotechnical engineering for the local site characterization, microzonation and site response studies.A MASW is a geophysical method, which generates a shear-wave velocity (Vs) profile (i.e., Vs versus depth)by analyzing Raleigh-type surface waves on a multichannel record. MASW system consisting of 24 channels Geode seismograph with 24 geophones of 4.5 Hz frequency have been used in this investigation. For the site characterization program, the MASW field experiments consisting of 58 one-dimensional shear wave velocity tests and 20 two-dimensional shear wave tests have been carried out. The survey points have been selected in such a way that the results supposedly represent the whole metropolitan Bangalore having an area of 220 km2.The average shear wave velocity of Bangalore soils have been evaluated for depths of 5m, 10m, 15m, 20m, 25m and 30 m. The subsoil site classification has been made for seismic local site effect evaluation based on average shear wave velocity of 30m depth (Vs30) of sites using National Earthquake Hazards Reduction Program (NEHRP) and International Building Code (IBC) classification. Soil average shearwave velocity estimated based on overburden thickness from the borehole information is also presented. Mapping clearly indicates that the depth of soil obtained from MASW is closely matching with the soil layers in bore logs. Among total 55 locations of MASW survey carried out, 34 locations were very close to the SPT borehole locations and these are used to generate correlation between Vs and corrected “N” values. The SPT field “N” values are corrected by applying the NEHRP recommended corrections.

Desarrollamos el curriculo con las TIC.

Se usan las nuevas tecnologías de la información y comunicación, TIC, para el desarrollo del currículo del centro mediante la creación de nuevas unidades didácticas, contenidos y actividades. Se plantean objetivos como buscar estrategias y procedimientos de trabajo propios y compartidos para el uso de las TIC en el centro; obtener conocimientos propios y válidos de las herramientas utilizadas para poder realizar tales materiales; trabajar asiduamente con soportes tecnológicos novedosos como cámaras de vídeo, pizarra digital o videoproyector que permitan investigar y actuar en el entorno del centro; y reflexionar sobre el impacto que genera el uso de las TIC en el proceso de enseñanza y aprendizaje. Para llevarlo a cabo, en primer lugar se forma al profesorado para que conozcan lo básico tanto del software como del hardware; poco a poco, los profesores elaboran sus recursos para las clases y finalmente lo ponen en práctica con los alumnos. Se incluye un CD-ROM con los materiales elaborados.

LEGO® bricks as building blocks for centimeter-scale biological environments

LEGO bricks are commercially available interlocking pieces of plastic that are conventionally used as toys. We describe their use to build engineered environments for cm-scale biological systems, in particular plant roots. Specifically, we take advantage of the unique modularity of these building blocks to create inexpensive, transparent, reconfigurable, and highly scalable environments for plant growth in which structural obstacles and chemical gradients can be precisely engineered to mimic soil.

Doppler-guided hemorrhoidal artery ligation with rectal mucopexy technique: initial evaluation of 42 cases

The treatment of hemorrhoidal disease (HD) by conventional hemorrhoidectomy is associated with significant morbidity, mainly represented by the postoperative pain and the late return to daily activities. Doppler-guided hemorrhoid artery ligation (DGHAL) is a minimal-invasive surgical treatment for HD that has been used as an alternative method in order to reduce these inconveniences. OBJECTIVE: To analyze the initial results of the DGHAL technique associated with rectal mucopexy in the treatment of HD. METHODS:Forty-two patients with stage I, III and IV hemorrhoids who were submitted to DGHAL were analyzed from December 2010 to August 2011. Eleven patients (26%) were stage II; 21 (50%), stage III; and 10 (24%), stage IV HD. All patients were operated by the same surgeon under spinal anesthesia and using the same equipment and technique to perform the procedure. The 42 patients underwent ligation of six arterial branches followed by rectal mucopexia by uninterrupted suture. Nine patients needed concomitant removal of perianal skin tag. In the postoperative, the following parameters were evaluated: pain, tenesmus, bleeding, itching, prolapse, mucus discharge and recurrence. The mean postoperative follow-up lasted four months (one to nine months). RESULTS: Tenesmus was the most common postoperative complaint for 85.7% of patients followed by pain, in 28.6%, perianal burning, in 12.3%, mucus discharge and perianal hematoma in 4.7%. Two patients had severe postoperative bleeding and required surgical haemostasis, one of which needed blood transfusion. Ninety-five percent of the patients declared to be satisfied with the method. CONCLUSION: Even though DGHAL has complications similar to those of other surgical methods, its results present less postoperative pain, allowing faster recovery and return to work. Studies with more cases and a longer follow-up are still necessary to assess the late recurrence.

Patients with oral tumors. Part 2: Quality of life after treatment with resection prostheses. Resection prosthetics: evaluation of quality of life

In the present study, the oral health-related quality of life of 18 patients (13 men and 5 women) was evaluated using validated questionnaires as proposed by the European Organization of Research and Treatment of Cancer (EORTC). The patients belonged to a cohort of 48 patients, whose prosthetic treatment was performed during the years 2004-2007. In the course of tumor resection, 12 patients underwent graft surgery and 14 patients radiotherapy. One patient required a nasal epithesis since resection of the nose became necessary. Five patients underwent a full block resection of the mandible, and tumor resection in 3 patients resulted in a large oronasal communication. Prosthetic rehabilitation was performed in all patients, and the follow-up period with regular care covered a minimum of 3 years. Eleven patients received dental implants for better support and retention of the prostheses. In spite of compromised oral conditions, functional restrictions, and some difficulties with the prostheses, the answers to the questionnaire were quite positive. The majority judged their general health as good or even excellent. The subjective perception of the patients may contradict the objective view by the dentist. In fact, the individual patient's history and experience provide a better understanding of the impact of oral tumors on daily life. The overall assessment identified 4 items that were perceived as major problems by all patients: swallowing solid food, dry mouth, limited mouth opening, and appearance. Prosthetic rehabilitation has only a limited influence on such problems.

Tradición y modernidad en la obra de Tadao Ando

Las nuevas relaciones internacionales establecidas en Japón a mediados del siglo XIX dieron lugar a una evolución de la cultura nipona, con un abandono paulatino de la tradición. La casa de té, origen de la arquitectura japonesa, quedó relegada al mundo rural, hasta caer casi en el olvido. Este proceso propició un espíritu crítico, del que surgieron arquitectos que defendían la búsqueda de un equilibrio entre el pasado y el presente. Tadao Ando ha destacado entre estos arquitectos por su tenacidad, humildad y perseverancia, cualidades que le han permitido desarrollar una arquitectura muy personal, cuyas obras representan su camaleónica capacidad, las preocupaciones de su cultura natal y una crítica social de la época moderna. Ando es un maestro de la abstracción ; un arquitecto atemporal y universal. Sus obras más representativas se sitúan en el periodo comprendido entre 1976-1995, cuando se recuperan los principios básicos de la casa de té: el diálogo entre arquitectura y naturaleza, los contrastes y la simplificación formal. El resultado conforma una arquitectura primitiva y moderna, con una precisión artesanal muy potente. Este trabajo pretende poner de manifiesto la influencia que la arquitectura tradicional japonesa y la arquitectura moderna internacional han tenido sobre la obra de Tadao Ando, un obra que, aun pasadas cuatro décadas, impacta profundamente en el observador y a nadie deja indiferente.
