PurposeThe structural behavior of reinforced concrete (RC) beams made with waste foundry sand (WFS) was examined in this study by using investigational data. Five RC beams were tested in this present work, four beams with varying WFS content and one beam with natural aggregates. The factors considered for studying the flexural performance of RC beams were WFS content (10%, 20%, 30% and 40%), 15% Ground Granulated Blast Furnace Slag (GGBS) is used as supplementary cementitious (SCM) content for all beams and tension reinforcement ratio (0.95%). The crack pattern of the RC beams with WFS (RCB1, RCB2, RCB3 and RCB4) was similar to that of referral beam–RCB0. The RC beams made with WFS (RCB1, RCB2, RCB3 and RCB4) show lesser number of cracks than referral beam–RCB0. It is observed that RCB1 beam shows higher ultimate moment carrying capacity than other RC beams. A detailed assessment of the investigational results and calculations based on IS: 456-2000 code for flexural strength exhibited that the present provisions conservatively predicts the flexural strength and crack width of RC beams with WFS and 15% GGBS. It is suggested that 10% WFS can be used to make RC beam.Design/methodology/approachIn this present work, four RC beams made WFS and one RC beam made with natural aggregates. 15% GGBS is used as SCM for all RC beams. After casting of RC beams, the specimens were cured with wetted gunny bags for 28 days. After curing, RC beams like RCB0, RCB1, RCB2, RCB3 and RCB4 were tested under a four-point loading simply supported condition. An assessment of investigational results and calculations as per IS: 456-2000 code provisions has been made for flexural strength and crack width of RC beams with WFS and 15% GGBS. The crack pattern is also studied.FindingsFrom this experimental results, it is found that 10% WFS can be used for making RC beam. The RCB1 with 10% WFS shows better flexural performance than other RC beams. RC beams made with WFS show lesser number of cracks than referral beam–RCB0. IS: 456-2000 code provisions can be safely used to predict the moment capacity and crack width of RC beams with WFS and 15% GGBS.Originality/valueBy utilization of WFS, the dumping of waste and environmental pollution can be reduced. By experimental investigation, it is suggested that 10% WFS can be used to make RC structural members for low cost housing projects.

With technological advancements, a large number of intellectual property (IP) cores can be integrated into a single chip. As a result, communication between these cores is critical. Such communication is achieved using Network on Chip (NoC) technology. NoC is an on-chip packet-switched network with IP cores connected to the network via interfaces, and packets are sent to their destinations via a multi-chip routing path. A router is the essential component of the NoC architecture, it must be designed efficiently to build a competitive NoC architecture. Verilog is used to design the router which supports five parallel connections. It uses store and forward type of flow control, round-robin arbitration, and deterministic XY routing. The building blocks of the router are FIFO, arbiter, and crossbar. The proposed architecture of the five port router is targeted to the Spartan 6 XC6SLX45 FPGA design platform and simulated in Xilinx ISE 14.5 software.

Fracture neck of femur is a leading cause of hospital admissions in elderly age group. The number of such admissions is on a rise because of increased longevity, osteoporosis and sedentary habits. Conservative methods of treatment is not acceptable because it results in nonunion with unstable hip and limitation of hip movement as well as complications of prolonged immobilization like bed sores, deep vein thrombosis and respiratory infections. Hemiarthroplasty remains the most common modality of treatment in our country. The time-tested unipolar prosthesis is being slowly replaced by bipolar prosthesis which is claimed to have a lower incidence of complications. Aim: This study was conducted to analyze the results of surgical management of fracture neck of femur using modular bipolar hemiarthroplasty. Methodology: The present study was a prospective study of fracture neck of femur admitted to Bapuji Hospital, and Chigateri General Hospital attached to J.J.M. Medical College, Davangere, treated with modular bipolar prosthesis. Results: In our series of 20 cases there were 8 males and 12 females, with a maximum age of 92 yrs, minimum age of 50yrs and an average age of 65 years. At the final one year follow up assessment with Harris Hip Score, 75% of the patients achieved an excellent or good result. Conclusion: Modular Bipolar hemiarthroplasty for fractures of the femoral neck provides better range of movement, freedom from pain and more rapid return to unassisted activity with an acceptable complication rate. Though out of the purview of the present study our experience with modular bipolar prosthesis have been significantly better than that with Austin Moore's Prosthesis.
