 Abstract

: Rapid change is being witnessed in terms of consumption patterns globally which is forcing the organisations to respond to such changes. The present-day organisations, therefore, need to be very dynamic and agile. The present article focusses on the concept and practice of agile organisations by describing the key features and substantiating them by presenting a case. The emerging trends in India like mounting applicability of digital technology, strategic cooperation among rivals, arrival of Industry 4.0, data sharing, ecosystem business model etc. are reshaping the economy's dynamics. Smooth transition from traditional organisations into living organisations is one of the best options to overcome the disruptive trends. Thus, it is needed to be agile maintaining the trade-off between stability and dynamism to create value for the stakeholders by establishing a network of teams which are capable of fast decision making. It portrays such factors which are inevitable for any organisation to be agile. A case study of Amazon India has been taken to understand the dynamics of agility cooperation and digitalisation in today's changing scenario.

 Abstract

The term "Visible Light Communication" (VLC) refers to the communication technology that utilizes the visible light source as a signal transmitter, the air as a transmission medium, and the appropriate photodiode as a signal receiving component. Visible light is thus, by definition, comprised of usually-perceivable electromagnetic waves. The visible spectrum covers wavelengths from 380nm to 750 nm. In this paper, we have studied the main concepts of and challenges to VLC. In this paper, we have also studied the overview of VLC technology, from its physical aspects and communication architecture to its main applications and research challenges.

 Abstract

Aim and objective: The aim of this study is to find out corneal sensitivity difference among three types of contact lens wearer (RGP lens, hydrogel Contact lens and silicon hydrogel contact lens) and non-contact lens wearer who walks in tertiary eye care center. This study is conducted experiments in order to detect whether changes in sensitivity were also different for the different zones. Method: A prospective study was performed which include total 80 subjects were recruited in this study among them 20 subjects were non-contact lens users, 20 subjects were RGP wearer, 20 were soft hydrogel lens wearer and 20 were silicon hydrogel lens wearer presenting at Dr. D.Y. Patil Institute of Optometry and Visual Sciences, Pune, from October 2022 to February 2023. Corneal sensitivity is measured using fine wisp of cotton and data analysis was done based on distribution. Result: Using fine wisp of cotton time taken for response in the form of blinking is measured in seconds and found mean time, for non-contact lens wearer is 0.361, for silicone contact lens wearer is 0.415, for hyderogel contact lens wearer is 0.619 and for RGP contact lens wearer is 0.781. statistical analysis showed that all the experimental groups (non contact lens users, silicone hydrogel lens wearer, hydrogel contact lens wearer and RGP lens wearer) significantly differed in terms of corneal sensitivity from each other. Conclusion: The study can be concluded by saying both soft and RGP lens wear produce a similar type of corneal sensitivity loss, although the mechanism for this loss is different for the two lens types. The recovery of corneal sensitivity loss is achieved by cessation of contact lens.

 Abstract

The pandemic coronavirus SARS CoV-2 in the world has caused a large infected population suffering from COVID-19. To curb the spreading of the virus, WHO urgently demanded an extension of screening and testing; thus, a rapid and simple diagnostic method is needed. The ease-of-use and rapid turnaround time of reverse transcription loop mediated isothermal amplification (RT-LAMP) and dry swab RNA extraction free method offer the potential to expand access to testing and decrease delays in diagnosis. In this study, ninety-four nasopharyngeal swabs were collected and tested for the presence of SARS-CoV-2 infection by RT-PCR (gold standard), RT-LAMP and dry swab method. In this study, 68 (72.3%) out of 94 patients were positive for SARS CoV-2 infection by RT-PCR. The overall sensitivity, specificity, positive predictive value and negative predictive value of RT-LAMP was 76.5%, 100%, 100% and 62%. The overall sensitivity, specificity, positive predictive value and negative predictive value of dry swab method was 66%, 100%, 100% and 53%. Hundred percent sensitivity was occurred in RT-LAMP and Dry swab method with Ct<20. In Ct 20-30, sensitivity of RT-LAMP and dry swab method was 87.5% and 82.5%. RT-PCR method required molecular facility; trained technician; and it takes several hours to get the results. Although sensitivity and specificity of RT-LAMP and dry swab methods are inferior to RT-PCR, they can be performed easily in the short period of time (less than 2 hours). Therefore, rapid and simple alternative molecular diagnostic methods should be considered for diagnosis of SARS CoV-2 infection.

 Abstract

Hormones play a crucial role in muscle growth and development. Testosterone, growth hormone, and insulin-like growth factor-1 (IGF-1) are the primary hormones that influence muscle growth. Testosterone promotes muscle protein synthesis by activating specific genes, which stimulate muscle cells to increase protein production. Growth hormone stimulates the production of IGF-1, which enhances muscle cell proliferation and differentiation. IGF-1 also stimulates muscle protein synthesis and inhibits protein breakdown. Insulin, in addition to its role in glucose metabolism, also plays a significant role in muscle growth by enhancing protein synthesis and reducing protein breakdown. Other hormones such as cortisol and estrogen can also influence muscle growth but have opposing effects to testosterone and IGF-1. Understanding the role of hormones in muscle growth can help individuals optimize their training and nutrition strategies to achieve their desired muscle development goals.

 Abstract

Abstract Sickle cell disease is a genetic disorder in which RBCs of patient becomes sickle shaped, thereby decreasing oxygen carrying capacity. It is not necessarily expressed since birth but may appear in any age. It is caused by a gene that is heterozygous, it results in abnormal haemoglobin known as HbS. The polymerization of HbS alters both the structure and function of erythrocytes, initiating a cascade of events that ultimately affect a wide range of tissues. In India, the disease is found in many people who are unaware of it and usually remain untreated. Indian government is also running few programs to make people aware and proceed for treatment. The disease was first discovered in 1910, since then a sequence of studies has been done, and still going on to fight against the disease. The frequency of disease is more in people of tribal area in India, who belong to specific caste.

 Abstract

Ultrasonic pulse velocity is a non-destructive method that is used to measure the properties of concrete and detect the damage of recycled aggregates and natural coarse aggregates concrete such as cracks. Due to the demolition of old concrete structures, waste concrete generates an environmental problem. To solve this problem, it is necessary to recover the recycled aggregates from concrete waste. The natural coarse aggregates is replaced by recycled coarse aggregates with the help of crushing the waste concrete and providing new concrete, but there should be a change in the compressive strength and damage occur within the concrete cube. The ultrasonic pulse velocity method was used to detect the damage of concrete such as cracks in the natural coarse aggregate and recycled coarse aggregates concrete. The specimen was a 150x150x150 mm cube concrete specimen. Each concrete cube was examined for velocity readings in sound, modulus of elastic and detected the concrete damaged by applying different loads on natural and recycled concrete. The damage level increases as the ultrasonic pulse velocity decreases. After analysis, the compressive strength of natural coarse aggregate is higher than recycled coarse aggregate concrete and the velocity of natural coarse aggregate is around 19.34% higher than recycled concrete and cracks occur more in recycled concrete as compared to natural coarse aggregate concrete. The higher reduced velocity shows crack formation. The main role of this work lies in comparative study of NCA and RCA, also determining the mechanical properties of concrete including young's modulus of concrete and detecting the damage within concrete through the help of the ultrasonic pulse velocity method.
