Comparative Study of Rigid Framed Structure and Tubular Structure
Abstract: India is a developing country and some cities are populated very densely and the population is increasing day by day. Industrialization leads to the migration of people to urban areas from rural areas where job opportunities are prominent. To provide housing space and working space to this extra population there is a need for horizontal development but due to lack of space availability vertical development is needed. Therefore, the demand …

Static and Dynamic Analysis of Conventional, Diagrid and Hexagrid Systems Across Different Storey Heights
Abstract: In structural engineering, multi-storey buildings’ seismic resilience in earthquake-prone areas is crucial. The seismic performance of proposed multi-story buildings with different heights (G+13, G+19, and G+27) is thoroughly examined in this study using traditional structural systems that are octagrid and hexagrid. Under seismic zone III conditions, the study evaluates important parameters such as storey drifts and storey displacements using the Response Spectrum Method. Each structural system's seismic response is assessed …

Automatic Detection of Air Holes Inside The Esophagus in CT Images
Abstract: Automatic esophagus segmentation is a challenging problem. The wall of the esophagus consists of muscle tissue, which has a low contrast to vessels, other muscles and lymph nodes. Shape and appearance can vary a lot. It appears solid if it is empty, but it can also be filled with air, remains of orally given contrast agent, or both. Even for a human, it is often impossible to accurately delineate the …

Polymer Chemistry-Driven Design of a Severable Dental Prophylaxis Instrument: Leveraging PEEK and Composites for Enhanced Functionality
Abstract: Polymer chemistry unlocks new possibilities for dental prophylaxis instruments by leveraging molecular design for enhanced functionality. This study explores Polyether Ether Ketone (PEEK), a semi-crystalline thermoplastic, in a novel instrument with a severable working end, featuring a tubular structure with internal screw threads (0.5–0.8 cm) anchoring replaceable elements via a threaded mechanism. PEEK’s aromatic backbone, alternating ether and ketone groups, yields a tensile strength of ~100 MPa, chemical inertness against …

Comparative Analysis of RCC Diagrid Building with conventional Building By E-TAB Software
Abstract: AbstractThe rapid growth of urban population and limitation of available land the taller structures are growing up now days. Structure design of high rise buildings is governed by the lateral loads due to wind or earthquake. Lateral load resistance of structure is provided by shear wall, wall frame, braced tube system, outrigger and tubular system. Recently the Diagrid-Diagonal grid system is widely used for tall buildings due to its structural …

Structural Design of Offshore Structures: A Review of Indian and International Standards
Abstract: Offshore structures—including fixed steel jackets, topside modules, offshore wind turbine support structures, and floating systems—are designed to withstand combined gravity, environmental, seismic, and operational loads under substantial uncertainty and limited access for inspection and repair. Structural design practice has historically relied on internationally recognized standards, particularly the American Petroleum Institute’s API RP 2A, the International Organization for Standardization’s ISO 19900 series, including ISO 19902 for fixed steel structures, and Det …

Platelets A Tiny Cell Fragments
Abstract: Platelets are disc-shaped, anucleate cells that are approximately 2-3 μm in diameter. Their primary function is to control hemostasis, or blood clotting, but they also play important roles in angiogenesis (the formation of new blood vessels) and innate immunity (the body's first line of defence against infection). With a diameter of just 2-3 microns, platelets are tiny, disc-shaped cells that lack a nucleus. While their main responsibility is to ensure …

Performance of Offshore Steel Jacket Platforms under Near-source Ground Motion Type Pulses
Abstract: Behaviour of jacket type offshore structures under ordinary ground excitations has already been addressed by a number of researchers. However, their performance under near-source ground excitations has not been particularly addressed in the literature. Records from recent earthquakes, such as the Kobe Japan (1995) and Chi-Chi Taiwan (1999), have revealed that the dynamic excitations in near-source are dominated by a large, narrow band and long period pulse caused by rupture …

Investigating The Alkalizing Potential of Chandanasava For Restoring Acid-Base Homeostasis in Renal Tubular Acidosis: A Computational and In Silico Pharmacological Study
Abstract: Chandanasava, a traditional Ayurvedic formulation, is recognized for its potential alkalizing properties, which may help restore acid-base homeostasis in conditions such as renal tubular acidosis (RTA). This study aims to investigate the active components of Chandanasava and their interactions with key renal target proteins, Pendrin and Carbonic Anhydrase II, which are essential for maintaining acid-base balance. An in silico approach was utilized to explore the pharmacological potential of the phytochemicals …

Application of flux cored arc welding (fcaw) without pre-heating for heavy structures in ship building fabrication & construction of heavy offshore structural steels
Abstract: In fusion welding processes, the reason often given to explain the need for preheating, controlling the inter pass temperature (in multi-pass welds), and post-weld heat treatment (PWHT) is to reduce the risk of residual stresses and it can be removed by heating weldment in the heat affected zone (HAZ). Cold cracking is a hydrogen embrittlement phenomenon, often referred to as hydrogen induced cracking or HAZ cracking. During the construction and …
