Abstract:

<strong>Background: </strong>A-scan ultrasound biometry (A-scan biometry/ A-scan)is mainly used to determine the axial length of the eye with the help of an ultrasound device. Axial length of eye is an important parameter to calculate Intra-ocular lens (IOL) power prior to cataract surgery. Different formulae to calculate the IOL power need axial length value along with keratometry value (calculated using a keratometer). Sometimes, the corneal compression caused during the A-scan measurement gives wrong values of the axial length. The objective of the present study was to compare accuracy

Abstract This study aims to explore the non-destructive detection method for such defects as debonding and delamination in carbon fiber/Ti alloy composite gun barrels during the preparation process. In this paper, the preparation method of composite barrel defective specimens is first introduced.

This is because voids are distributed in the through-thickness. The results indicated that the absorption behavior could be used to predict the void volume.

Abstract:

Non-destructive testing is needed for the evaluation of quality and safety of concrete structures in the field of civil engineering. The imaging of concrete/reinforced cement concrete structures (RCC) is a challenging task due to the non-homogeneous properties of the concrete material. To address this challenge, a novel real-time, re-configurable, four-channel embedded system has been designed and developed to image the internal details of the concrete samples using the water immersion pulse-echo (PE) mode under automation, which needs access from one side of the structure. The system performs

Abstract:

Introduction: The eye hospitals of low-income countries including Nepal are not equipped with imaging modalities including CT scan, UBM and Pentacam but most of them have ophthalmic ultrasound. We evaluate the utility of routine ultrasound for proper localization and confirmation of the intra-lenticular foreign body along with detection of the status of the posterior capsule using immersion technique. Case: Four consecutive cases with intra-lenticular foreign bodies presenting to the vitreo-retina department of Lumbini Eye Institute were included in the study. Ultrasound immersion technique wa

Abstract:

The authors aim to consider a clinical case of treatment of a newborn baby with gastroschisis by staged immersion of intestinal loops and anterior abdominal wall plasty. A defect of the anterior abdominal wall was detected by ultrasound scan at 15 weeks gestation of a baby born at 33 weeks gestation (the Apgar score is 6–7, weight is 2,000 g). The child had a surgery 5 hours after the birth. After revision of the retained organs a pronounced visceral and abdominal disproportion was found. It was decided in favor of two-stage procedure of gastroschisis. A silicon bag with an elastic fixing ring

Corrosion is a serious problem in every industry and can cause losses in production leading to large financial losses. International legisation body has drawn offshore chemical into several categoris based on biodegradation, bioaccumulation and toxicity. Otherwise, the inhibitor is not accept to be used as they are harmful to environment. Therefore, most industries are looking for green inhibitor for An electrochemical test has been carried out to determine the corrosion rate of carbon steel.

The electrocatalytic oxidation of formaldehyde on Nickel-Poly (o-toluidine) - polyvinylalcohol modified glassy carbon electrode (Ni-P(OT)-PVA/GCE) was developed. This involves in situ electropolymerization of o-toluidine at GCE, which is following to the incorporation of Ni (II) to polymeric layer by immersion of modified electrode in 1.0 M nickel sulphate solution. The general electrochemical behavior was characterized by cyclic voltammetry and chronoamperometry methods in alkaline media. The results showed that the Ni-P(OT)-PVA/GCE system exhibits a significant electrocatalytic activity towa

Abstract:

In particular, CFRP (carbon fiber reinforced plastics) composite materials have found wide applicability because of their inherent design flexibility and improved material properties. CFRP composites were manufactured from uni-direction prepreg sheet in this paper. However, impacted composite structures have 50-75% less strength than undamaged structures. It is desirable to perform nondestructive evaluation to assess material properties and part defect in order to ensure product quality and structural integrity of CFRP. In this work, a CFRP composite material was nondestructively characterized

Abstract:

In the manufacturing of electric vehicles, aluminum is widely used to enhance lightweight properties and heat dissipation in vehicle parts. However, aluminum is prone to issues such as internal pore formation and reduced strength compared to the base material after welding. Therefore, it is crucial to select an appropriate welding process based on the vehicle part's purpose, thickness, geometry and quality requirements. Friction Stir Welding (FSW) has become increasingly popular due to its effectiveness in reducing defects such as porosity, cracks, and thermal distortion. Various Non-Destructi
