The analysis of digital/analog signals with the objective of measuring, reconstructing, improving quality, compressing and recognizing patterns is signal processing. Various biosignals are electrocardiogram, electroencephalogram, electroretinogram etc. Various aspects of processing biomedical signals are evolving with time and technology. The aim of this article is to report various packages and their utility in processing biomedical signals. Labview, PhysioTrace toolkit etc are the amongst few packages discussed in this paper. The manuscript is intended to provide insight into biomedical signals in simple form without going into deep explanations of mathematical representation. Various models for processing of biomedical signals have been explained. Several advantages and disadvantages of different models have been summarized in this article. [ABSTRACT FROM AUTHOR]

The role of polymers in drug delivery today cannot be concealed by any means. Three dimensional printing technique provides facility of transforming a 3D design into a real three dimensional object by deposition of polymers layer by layer. It is evolving at rapid pace owing to the advantages that it offers over conventional drug delivery dosage forms like it is tailor-made medications in pharmacies with specific dose of drug as per individual patient requirements (Spirtam being the Ist USFDA approved 3D printed tablet). The objective of this article is to summarize the recent trends in use of 3D printing technology in drug delivery by utilization of polymers. Various types of approaches that are currently employed for designing 3D printed dosage form have been discussed in this paper. The basic method of 3D printing of each class is explained. Various dosage forms which have been developed using various approaches along with drug that has been delivered and polymer utilized in the formulation of such dosage forms have been summarized. Further, the paper also discusses practical challenges of this technology and future opportunities and scope of this technology for drug delivery have been explained. [ABSTRACT FROM AUTHOR]

Expanded Polystyrene Foam (EPS) is commonly used in our daily lives. EPS is used in different appliances like packing material and household appliances and also for construction material. Expanded polystyrene is light weight and it is easy to transport and install. There is around 10 million metric tons production of expanded polystyrene around the world. But on the other side, EPS is non-biodegradable foam it cannot decompose in nature. It is well known that the waste of expanded polystyrene foam has caused environmental problems like land and water pollution. This material serious impacts the human health and aquatic environment. But now days, a new recycling technique have been introduced by the help of this technique 20 % volume of EPS waste has been reduced. Using a heat treatment procedure, waste EPS is recycled in this approach. Modified expanded polystyrene waste (MEPS) is the substance that results from the heat treatment. In addition, using waste expanded polystyrene in concrete technology is a frequent way to recycle wastes EPS. We will explore the qualities and applications of EPS in this article, as well as how to reuse or recycle expanded polystyrene trash. The goal of this study was to find out what information was available, primarily on EPS recycling and the disadvantages of recycling for the polymer industry. [ABSTRACT FROM AUTHOR]

Emulgel, which mixes a gel and emulsion dual control launch mechanism, has emerged as one of the most captivating topical delivery systems. Topical drug utility has the capacity to deliver medication immediately to the web site of motion at the same time as additionally allowing the drug to be administered for an increased time at affected location. Objective of this take a look at was to create a Clarithromycin emulgel system the usage of Carbopol934 as a gelling agent. The generated emulgel's pH, appearance,drug content material, spreadability, and in-vitro drug launch have been all evaluated. Emulgel became a hydrophobic drug shipping method that had the capacity to be beneficial. Neem oil, which is also antibacterial and antimicrobial, turned into used as a penetration enhancer. The generated emulsion changed into poured into the gel base. In all Emulgels generated, bodily properties, homogeneity, consistency, spreadability, in-vitro release, and balance have been all top. the use of a diffusion cellular with a dialysis membrane because the receptor media and phosphate buffer 6.8pH as the discharge medium, the in-vitro release fee of emulgel became measured. system F2 became chosen as the pleasant method in this observe as it had the very best drug release price. The emulgel was established to be solid in terms of bodily appearance, pH, and drug content material over a two-month duration at all temperatures and situations. They demonstrate the synergistic outcomes of neem oil. [ABSTRACT FROM AUTHOR]

In situ gel-forming solutions are injected into the eye as drops and undergo a sol-gel transition in the cul-de-sac., may overcome in situ gel-forming systems, which are administered as drops, have a lower bioavailability and therapeutic response than typical ophthalmic solutions due to the medication's rapid precorneal excretion. It's a one-way street. The current research focuses on the creation and testing of an anti-histamine ophthalmic delivery device. Ketotifen is a drug that is used to treat obesity. Based on the notion of in situ gelations, fumarate for a temperature-activated in situ gel, poloxamer was utilized as the gelling agent, along with chitosan as a viscosity enhancer. The visual appearance and clarity of the optimized formulations F1, F2, and F3 were assessed. The optimized formulations were therapeutically efficacious, stable, non-irritant, and provided sustained drug release over eight hours. As a result, the newly developed method offers a viable alternative to standard eye drops. [ABSTRACT FROM AUTHOR]

In the present study, the thermal performance of a finned tube heat exchanger using aluminium oxide-deionized water nano-fluid has been evaluated. A counter flow type finned tube heat exchanger has been selected for experimentation. The volume concentration of aluminium oxide mixed with deionized water has been procured as 0.1, 0.2, 0.3, and 0.4% at a temperature range of 10-90°C. Stable nano-fluid dispersion is prepared with sodium dodecylbenzene sulphonate and sodium hexametaphosphate which is used as a stabilizer. The experiments are conducted with different flow volume for both hot and cold fluid ranging from 75-150 LPH. The thermal performance of heat exchange is found to have enhanced with the use of nano-fluid. The maximum LMTD has been found to be 25.70°C and 19.65°C with and without nano-fluid respectively.

Cumulative dose gamma radiation effects on current-voltage characteristics of GaN Schottky diodes have been investigated. The different area diodes have been fabricated on AlGaN/GaN high electron mobility transistor (HEMT) epi-layer structure grown over SiC substrate and irradiated with a dose up to the order of 104 Gray (Gy). Post irradiation characterization shows a shift in the turn-on voltage and improvement in reverse leakage current. Other calculated parameters include Schottky barrier height, ideality factor and reverse saturation current. Schottky barrier height has been decreased whereas reverse saturation current shows an increase in the value post irradiation with improvement in the ideality factor. Transfer length measurement (TLM) characterization shows an improvement in the contact resistance. Finally, diodes with larger area have more variation in the calculated parameters due to the induced local heating effect. [ABSTRACT FROM AUTHOR]
