Low Power Systolic Array Based Digital Filter for DSP Applications

Main concepts in DSP include filtering, averaging, modulating, and correlating the signals in digital form to estimate characteristic parameter of a signal into a desirable form. This paper presents a brief concept of low power datapath impact for Digital Signal Processing (DSP) based biomedical application. Systolic array based digital filter used in signal processing of electrocardiogram analysis is presented with datapath architectural innovations in low power consumption perspective. Implementation was done with ASIC design methodology using TSMC 65 nm technological library node. The proposed systolic array filter has reduced leakage power up to 8.5% than the existing filter architectures

Achieving asepsis of banana leaves for the management of toxic epidermal necrolysis

Background: Banana leaf is used in many centers in India during the care of patients with toxic epidermal necrolysis (TEN) and other extensive blistering disorders. Sepsis is an important cause of death in TEN patients and use of banana leaf may be a source of such infection. Aims: We conducted this study to detect the bacterial flora of the banana leaf and to examine various methods of rendering the leaf aseptic. Methods: Five pieces of banana leaf, 2 x 2 cm in size, were cultured separately in blood agar as follows: One piece was heated over a flame and one was soaked in boiling water and one was autoclaved. Methylated spirit was applied over one piece and ignited. One piece was placed on the media, 'as is.' The Petri dishes were incubated examined after 48 h. Results: All the pieces except the autoclaved specimen of the leaf grew coagulase-negative staphylococci (CONS) when aseptic precautions were not maintained and aerobic spore bearers when all aseptic measures were subsequently instituted during the procedure. Conclusion: We recommend measures to prevent possible transmission of bacterial infection by the leaf. Autoclaved and aseptically handled banana leaves may be used to reduce chance of infection in the treatment of TEN

Effect of Various Factors on Plant Fibre-Reinforced Composites with Nanofillers and Its Industrial Applications: A Critical Review

The growing awareness of the environmental damage caused by petroleum-based fibres has led to an increase in renewable and biodegradable resources. The continually growing demand for eco-friendly and sustainable materials pushes automakers and material researchers to consider the ecological importance of their materials during fabricating, recovering, and disposal. Natural fibre-reinforced composites (NFRC) have been introduced into the automobile market substantially over the last ten years due to their renewability, eco-friendliness, recyclability, biodegradability, light weight, better specific strength, good resistance to impact and corrosion, abundantly available, ease of processing, and cost-effectiveness. Due to cost-effectiveness and weight reduction, NFRC is becoming a better replacement for petroleum/synthetic fibres like aramid, kevlar, carbon, and glass fibre-reinforced composites, and the transportation sector has instigated the use of these materials in many applications like car interiors and exteriors, dash boards, bumpers, spoilers, seat covers, and mirror casings. NFRC with nanofillers is gaining more attention in the field of engineering, particularly for automotive, defense, building, and construction applications due to better aspect ratio, larger surface area, and attractive properties. The mechanical, tribological, and thermal properties of plant fibre-reinforced composites can be improved through the incorporation of organic or inorganic nanofillers. The present review profoundly explores the effects of various factors influencing NFRC with nanofillers. This paper also summarises the effects of various chemical reagents, fabrication techniques, and industrial applications of NFRC
