Strengthening of RC Beams with Large Openings in Shear by CFRP Laminates: Experiment and 2D Nonlinear Finite Element Analysis
S.C. Chin,N. Shafiq,M.F. Nuruddin
Research Journal of Applied Sciences, Engineering and Technology , 2012,
Abstract: This study presents the experimental study and numerical analysis of Reinforced Concrete (RC) beams with large square openings placed in the shear region, at a distance 0.5d and d away from the support, strengthened by Carbon Fiber Reinforced Polymer (CFRP) laminates. This research aims to investigate the strength losses in RC beam due to the presence of large square openings placed at two different locations in shear region. Also, in order to re-gain the beam structural capacity loss due to the openings, strengthening by CFRP laminates around the openings were studied. A total of six RC beams were tested to failure under four point loading including control beams, un-strengthened and strengthened RC beams with large square openings in shear region at a distance 0.5d and d away from the support. The CFRP strengthening configuration considered in this study was a full wrapping system around the square openings. A nonlinear finite element program, ATENA was used to validate the results of the tested beams. Comparisons between the finite element predictions and experimental results in terms of crack patterns and load deflection relationships are presented. The crack pattern results of the finite element model show good agreement with the experimental data. The load midspan deflection curves of the finite element models exhibited a stiffer result compared to the experimental beams. The possible reason may be due to the perfect bond assumption between the concrete and steel reinforcement.
Vegetable fibers as multifunctional materials
Amico, S.C.;
Matéria (Rio de Janeiro) , 2010, DOI: 10.1590/S1517-70762010000200037
Abstract: concerns related to the ever-growing use of raw-materials from non-renewable sources by modern society is driving the interest of the academic and scientific sectors for a new concept of material, which takes into account not only mechanical performance, cost and availability, but also environmentally-related issues, such as biodegradability, renewability and energy use, along with the promotion of social and economical development of the economically-challenged segment of the population. vegetable fibers have been used in many home-made objects, such as ropes and artcraft, for perhaps as long as humanity exists. however, these fibers present a combination of interesting properties which enables their use in a wide variety of sectors. this invited article will review the work recently carried out by the author in collaboration with various researchers from ufrgs, ufpr and ucs, and will be divided into three case studies, focusing on the use of vegetable fibers for oil sorption, as infiltration (flow) medium and as reinforcement for polymer composites, promoting their use in more demanding and rewarding applications.

Medicine : Science or Art?
S.C. Panda
Mens Sana Monographs , 2006,
Abstract: Debate over the status of medicine as an Art or Science continues. The aim of this paper is to discuss the meaning of Art and Science in terms of medicine, and to find out to what extent they have their roots in the field of medical practice. What is analysed is whether medicine is an "art based on science"; or, the "art of medicine" has lost its sheen (what with the rapid advancements of science in course of time, which has made present day medicine more sophisticated). What is also analysed is whether the "science of medicine" is a pure one, or merely applied science; or the element of science in it is full of uncertainty, simply because what is accepted as "scientific" today is discarded by medical practitioners tomorrow in the light of newer evidence. The paper also briefly touches upon how, in the field of present medical education, the introduction of medical humanities or humanistic education has the potential to swing the pendulum of medicine more towards the lost "art of medicine". The paper concludes by saying that the art and science of medicine are complementary. For successful practice, a doctor has to be an artist armed with basic scientific knowledge in medicine.
Integrated management of web blight of urd and mung bean
Indian Phytopathology , 2012,
Abstract: The treatment combinations based on bio-agent Gliocladium virens (Trichoderma virens), Karanj (Pongamia glabra) cake, carboxin and Rhizobium were evaluated in integration of three methods as soil application,foliar spray and seed treatment for the management of web blight of urd (Vigna mungo) and mung (Vigna radiata) bean caused by Thanatephorus cucumeris (=Rhizoctonia solam) under sick field conditions. The integration of soil application of Karanj cake (2 q ha'), seed treatment with G. virens (10 6 spores/ml/10g seed) + carboxin (1 g kg-1)+ Rhizobium sp.
Integrated management of web blight of urd/mung bean by bio-seed treatment
Indian Phytopathology , 2012,
Abstract: Seed treatment with slurry or water mixed spores of Trichoderma viride and Glioc/adium virens gave the best protection to germinating seeds of urdlmung bean against Rhizoctonia solani. Sorghum grain based powder @ 2g kg-1seed also provided good protection and its efficacy

Rural nutrition interventions with indigenous plant foods - a case study of vitamin A deficiency in Malawi
Babu S.C.
Biotechnologie, Agronomie, Société et Environnement , 2000,
Abstract: Identification, propagation, and introduction of a nutritionally rich, indigenous plant species in the existing cropping system are presented in this paper as a method of rural nutrition intervention. A case study of Moringa (Moringa oleifera Lam., Moringaceae), which is a common tree in Malawi and one of the richest sources of vitamin A and vitamin C compared to the commonly consumed vegetables is presented to address the problem of vitamin A deficiency. After a brief review of the prevalence of vitamin A deficiency and the efforts to reduce its incidence in Malawi, Moringa is suggested as a potential solution to the problem. A framework for designing nutrition intervention with Moringa is described for actual implementation. It is argued that attempts to identify, document, and encourage the utilization of nutrient-rich indigenous plants could be cost-effective, and a sustainable method of improving the nutritional status of local populations.
