In corrosion protection study, it is important to develop economically attractive test method for mitigation of corrosion damage of coated structure. Faster predication of protective behavior of any coating is a big challenge for the coating industries. In present work, in-house waterborne anticorrosive coating system was selected for study. The corrosion protection of coating evaluated as per ...

Poly(ADP-ribose) polymerase (PARP) inhibition has recently been identified as a novel approach to treatment of experimental peripheral diabetic neuropathy (PDN). However, long-term inhibition of PARP, an enzyme involved in DNA repair, can potentially result in premature aging, loss of genome stability, and other side effects. This study evaluated potential synergistic interactions between low d...

pulse-width modulated (pwm) adjustable frequency drives (afds) are extensively used in industries for control of induction motors. it has led to significant advantages in terms of the performance, size, and efficiency but the output voltage waveform no longer remains sinusoidal. hence, overshoots, high rate of rise, harmonics and transients are observed in the voltage wave. they increase voltag...

The growing variability in nanoelectronic devices due to uncertainties from the manufacturing process and environmental conditions (power supply, temperature, aging) requires increasing design guardbands, forcing circuits to work with conservative clock frequencies. Various schemes for clock generation based on ring oscillators have been proposed with the goal to mitigate the power and performa...

The aim of this paper is to describe existing ISO standards and current activity concerned with thermal comfort. It describes how an ISO standard is produced from a new work item proposal (NP) to publication as an international standard (ISO). A framework is provided for the assessment of ISO standards and their revisions. Standards should be valid, reliable, useable, and with sufficient scope ...

Covalently crosslinked protein networks produced from whey nanofibrils (PNFs) are demonstrated to be sustainable high-performance foams that show chemical resistance and mechanical strength, stiffness, toughness on harsh aging at 150 °C. The aged able retain their properties 180 °C for as long 24 h, far exceeding the of most classical petroleum-based thermoplastics. further developed into soft ...

Background and Aim: Excessive production of free radicals and the accumulation of oxidative damages play an important role in accelerating the aging process. However, one of the ways to fight against aging and related diseases is through physical activity. The aim of the present study was to investigate the effect of 12 weeks of resistance training on oxidative stress indicators (8-iso-prostagl...

This paper investigates the morphology, thermal, and electrical properties of LDPE (low-density polyethylene)-based nanocomposites after thermal aging. The FTIR (Fourier transform infrared spectroscopy) spectra results show that thermo-oxidative reactions occur in neat LDPE and LDPE/SiO₂ nanocomposites when the aging time is 35 days and in LDPE/MgO nanocomposites when the aging time is 77 days....

In this study, the aging and deterioration mechanisms in the plastic bonded explosives (PBXs) and their components as well as standard methods for their evaluating are presented. Also, the techniques developed for the prediction of chemical lifetime and service life of PBXs will be reviewed and analyzed. These methods cite the lifetime prediction methods based on weight/energy loss by thermal a...
