 Abstract

A review of non-destructive testing (NDT) procedures for the assessment of composites is given. The review takes into account the capabilities of the most popular techniques used in composite NDT applications, including Visual Testing (VT or VI), Ultrasonic Testing (UT), Thermography, Radiographic Testing (RT), Electromagnetic Testing (ET), Acoustic Emission (AE), and Shearography Testing, as well as the benefits and drawbacks of each technique. Additional techniques are categorised based on their inherent qualities and applicability. Typically, an NDT evaluator performs the evaluation using just one non-destructive test method. Using just one test technique is allowed if the scope of the job is simple. A mixture of several test methods is necessary because there are situations when a single test method does not give sufficient information about the material integrity Following that, approaches were grouped according to their inherent qualities and applicability. Non-destructive testing is frequently used in power plants, the aerospace, nuclear, military, and defence industries, as well as storage tank inspection, pipe and tube inspection, and the characterisation of composite flaw. The extent of NDT use for composite materials is the primary emphasis of this paper.

 Abstract

Despite number of initiatives for improving living conditions of the tribals, the progress is not up to the mark. The forests are depleting at faster rate, though the government records do not reflect the reality at ground level. These forests are in no way sustaining food requirements of forest dwellers through their traditional means of hunting and gathering. Mostly they are dependent on agriculture either as cultivators or agriculture labourers. They are malnourished, poor, largely illiterate and rank miserably low in all sorts of health indicators despite of their wealth of traditional knowledge of keeping healthy. Their literacy levels are not adequate to compete with the general population and at the same time they decline to do any work in their native places. In this paper, an attempt is made to bring out general economic conditions, health issues and role of NGOs. Some of these issues are discussed based on two research works: one on Yerukula tribe, a Dispersed Tribal Group (DTG) inhibiting in Prakasam, Nellore and Chittoor districts of Andhra Pradesh and a baseline survey (for CARE-STEP) of tribes inhibiting in jungles in North coastal districts of Andhra Pradesh.

 Abstract

The present paper focuses on preservice teacher's perspectives towards e learning. Now days, the education system is getting much closer with e learning. After Covid pandemic, e learning, online education, digital education are becoming the common words. Though , the world is returning on its track, the education system has got a new avenue in terms of e learning. Ranging from schools o professional institutions, everyone is now acquainted with the concept of e learning. So research undertook this research to study the perspectives of Preservice Teacher Education Students towards e learning. In conclusion researcher stated that, most of the students of teacher education has well developed perspective towards e learning and they are looking positively and also keeping themselves engaged in acquiring new skills required for e learning.

 Abstract

This study applies queuing theory to hospital management. The purpose of this study is to describe and categorize issues of urgency in medical cases with respect to patient allocation issues. It employs first-come-first-served, queue-discipline, Poisson arrival of patients and exponential service time, first-come-first-served, queue-discipline. A queue model used to estimate patient wait times, service consumption, model system design, and reservation system ratings. A queuing system helps minimize patient wait times and reduce server load. H. Doctors, nurses, hospital beds, etc. Queues are not new, but hospitals have recently started using them effectively.

 Abstract

This paper explores the challenges of project logistics in global maritime supply chains. Project logistics refers to the planning, coordination, and execution of complex transportation projects, such as the shipment of oversized or high-value goods. In the context of global maritime supply chains, project logistics can pose significant challenges due to factors such as varying regulations, cultural differences, and the need for specialized equipment and expertise. The paper discusses these challenges in detail and offers potential solutions for overcoming them, including the use of technology and collaboration between stakeholders. The findings of this paper can be valuable for companies and organizations involved in global maritime supply chains who are seeking to optimize their project logistics operations.

Present study deals with the diversity of freshwater fungi from submerged plant debris in two water bodies namely Khindsi irrigation project and Totladoh Damof Nagpur district of Maharashtra. Five species were observed from submerged plant debris collected from these two water bodies from Nagpur district of Maharashtra. The species found are Aniptodera chesapeakensis, Annulatascus palmietensis, Chaetomastia typhicola, Natantispora retorquens and Panorbis viscosus. All these fungi are reported for the first time from Nagpur distrtict. The fungal species observed are illustrated and described in this paper.

 Abstract

This paper proposes an authentication system that combines One-Time Password (OTP) and Quick Response (QR) code technologies to enhance security and user experience. The system generates an OTP and a unique QR code for each authentication attempt, which can be scanned using a mobile device to complete the authentication process. The QR code contains encrypted information about the user's identity and the OTP, which is verified by the server. The proposed system provides a secure, convenient, and efficient method for user authentication, which is crucial in today's digital world. An e-authentication system that uses OTP and QR code technology is a secure and efficient method for authenticating users in online transactions. This system combines the benefits of OTP and QR code technology to provide a two-factor authentication mechanism that is convenient for users and effective in preventing unauthorized access. This system aims to address the vulnerabilities of traditional username and password authentication by providing an additional layer of security through two-factor authentication. the system aims to prevent unauthorized access to online services and transactions. The system aims to provide a user-friendly and convenient authentication method that can be easily integrated into existing online platforms. It protect sensitive information and ensure that only authorized users can access online services and transactions.

 Abstract

Secondary iris cysts are a rare complication after cataract surgery. Reports of iris cysts after conventional phacoemulsification are rare. We report a case of an epithelial inclusion cyst of the iris after cataract surgery, causing elevated intraocular pressure, which was successfully treated with a neodymium-doped yttrium aluminum garnet (Nd YAG) laser. No recurrence was found by slit lamp examination two months after treatment.
