Abstract: Weightlifting shoes have played a crucial role in enhancing the performance and safety of athletes in sports such as
Olympic weightlifting and powerlifting. This review paper has explored the impact of weightlifting shoes on the kinetics
and kinematics of weightlifting movements. A comprehensive literature review has revealed that weightlifting shoes
significantly alter the mechanics involved in squats, snatches, and clean and jerks. The use of weightlifting shoes has been
shown to benefit experienced athletes by boosting their performance, however, further studies have been recommended for
beginner and intermediate-level athletes to understand the full potential of these shoes. This review has provided valuable
insights into the benefits and considerations of incorporating weightlifting shoes in training and competitions, highlighting
the need for tailored research to optimize athletic performance

Authors: Balbudhe, Snehal; Khan, Debishree; Mandavgane, Sachin; Lakhawat, Gajanan; Pawade, Vijay
Abstract: This study has reported a simple and cost-effective method for the synthesis of the corrosion inhibitor zinc vanadate
nano-pigment. Further, the prepared pigment has been well characterized by different techniques such as XRD, FESEM,
FTIR, EIS, etc. The formation of zinc vanadate nanoparticles has been confirmed by the FESEM. Zinc vanadate
nano-pigment-based anti-corrosive coating has been prepared in epoxy resin and has been compared with zinc phosphatebased
epoxy coating for the anticorrosive properties using an electrochemical impedance test (EIS test). The result has
indicated that zinc vanadate nano-pigments have exhibited better performance in coating applications and also have shown
high inhibitor efficiency and a lower corrosion rate. Thus, it has found potential scope in anticorrosive coating applications.

Authors: Remalli, Vidya Sagar; Purathekandy, Anjali
Abstract: This article reports the characteristics of acoustic emissions (AE) generated during the electrochemical corrosion process
in reinforced concrete (RC) beam specimens. The RC beam specimens have been subjected to electrochemical corrosion in a
NaCl solution container that has been present in the laboratory. The gaussian mixture modeling (GMM) algorithm has been
employed to classify the AE generated during both the corrosion of steel rebar and the fracturing of concrete. A sudden
increase in the generation of AE signals has been observed with the initiation of steel-rebar corrosion in the RC beam.
The AE hits recorded during the initial stages have exhibited short durations of less than approximately 0.5 milliseconds.
However, as corrosion has progressed, both the signal strength and the duration of the AE waveforms have increased.
The extended monitoring duration has also affected the position of the knee in the cumulative AE signal strength (CSS)
curve. The transition from micro-cracks to macro-cracks has been identified through the AE waveform parameter ‘duration’,
which, in the later stages of accelerated corrosion, has ranged between 20 to 40 ms. The study reported in this article has
been related to very accelerated corrosion, compared to an in-situ case where corrosion is much slower and likely
environmental sources have dominated the total AE released. However, the findings of the present study may prove valuable
for long-term monitoring of the corrosion process in RC structures.

Authors: Parashuram; Kumar, Chakresh; Kumar, Ghanendra
Abstract: In this work, the effectiveness of three-stage highly nonlinear fiber (HNLF)-based self-phase modulation (SPM)
regeneration wavelength conversion has been examined. Through the nonlinear Schrödinger equation (NLSE), nonlinear optical
effects in fiber have been explored, which has been important to comprehend SPM-based conversion. In addition, mathematical
exploration has been done on the principles of wavelength conversion, which have been mainly controlled by four-wave mixing
(FWM), SPM, and cross-phase modulation (XPM). This work has offered the theoretical underpinnings of SPM-based
wavelength conversion. We have investigated the features of HNLF, have delved into the architecture of the suggested threestage
conversion system, and have examined performance measures including optical power spectrum, RF spectrum quality
factor (Q) and bit error rate (BER) in relation with bit rate (Gb/s). In the realm of regenerative wavelength conversion, this study
has unveiled a spectrum of quality factor (Q) values across three consecutive stages, each associated with specific data rates. At
a bit rate of 60 Gb/s, the quality factor at the first, second, and third stages for a 100 km length of HNLF has been achieved
19.36 dB, 19.39 dB, and 19.41dB. Additionally, realized quality factor at first, second, and third stages for a 50 km length of
HNLF at a bit rate of 60 GB/s has been found as 24.96 dB, 25.26 dB, and 25.41 dB. It has been concluded from the findings
that at each stage, bit error rate has reduced and quality factor has increased due to parallel combinations of OBPFs and 3R
regeneration. The results have exquisitely highlighted the complex interaction between the number of stages used, HNLF
length, and data rate for accomplishing optimal wavelength conversion of an optical signal from 1545 nm to 1555 nm.
