Abstract:

Preliminary Hazard Analysis (PHA) is a semi-quantitative evaluation executed to recognize, early within side the layout and definition level of a system, all potential hazards and hazardous events that can cause an accident, classify identified hazardous events according to their severity and identify the required hazard controls and their respective follow-up actions. It is a great tool for beginning to recognize the hazards of a system. In some cases, a PHA is all that is needed to analyse a simple system. It is also the first step in the hazard analysis of more complicated systems. This rev

Abstract Trains are public transportation whose operations prioritize passenger safety. There have been 701 train accidents, resulting in 343 deaths and environmental damage from 2007 to 2023. The braking, propulsion, and bogie systems that function for train movement contribute to accidents, such as derailments and collisions. Actions to minimize these risks are by conducting preliminary hazard analysis (PHA) and allocating safety integrity levels (SIL). The purpose of this study is to explore steps to minimize train accidents using the PHA method and SIL allocation. PHA is carried out throug

Firefighters have among the most physically and psychologically challenging jobs in the world, incurring more than 80,000 (NFPA, 2014) injuries each year. Firefighter training is crucial, as higher knowledge and experience levels are inversely proportional to their risk of injury or work-related illness (Gonzalez, 2002). However, a paradox is created in that the training itself is the third highest cause of firefighter injury (Burgess, 2014). Therefore, enhancing training safety is paramount to creating a safer overall work environment for firefighters. This study focuses on a particularly haz

Abstract:

Abstract Land conversion causes a decrease in the occupation of paddy fields areas. Furthermore, the existing paddy fields that are mismanaged cause land degradation also. This study assesses the land quality index (LQI) in Jember Regency, East Java, Indonesia. The novelty of this research is that it combines the assessment of soil and land parameters (terrain, topography, climate, irrigation infrastructure, erosion, and flooding). Input data for this study consist of land cover, soil type, and slope maps. The procedure includes (1) spatial analysis to create the unit soil map area, (2) prepar

This works attempts to implement artificial neural networks (ANN) for modeling Seismic-Isolation (SI) systems consisting of Natural Rubber Bearings and Viscous Fluid Dampers subject to Near-Field (NF) earthquake ground motion. Fourteen NF earthquake records representing two seismic hazard levels are used. The commercial analysis program SAP2000 was used to perform the Time-History Analysis (THA) of the MDOF system (stick model representing a realistic five-story base-isolated building) subject to all 14 records.

Abstract:

Risk assessment is one of the prerequisites for understanding its causes and possible consequences. We base our risk assessment on the principles described in the European standard EN 31000 - Risk Management Process. This standard comprehensively describes the continuous activities that are necessary in managing risks and minimizing their possible adverse effects on the operation of the system under investigation. In this activity, it is necessary to first identify the existing risks, then analyze and evaluate the identified risks. In the analysis of existing risks, it is possible to use both

Methods: CMS for 392 of 431tumors were defined using a custom CRC Nanostring panel (39 CMS classification not possible).

Bioelectrical Impedance Analysis (BIA) is a simple, non-invasive, real-time diagnostic technique routinely used in human clinical practice to assess body composition and hydration status. BIA raw parameters, particularly the Phase Angle (PhA), are gaining attention as markers of congestive states in humans, as body electrical impedance can be affected by variations in body water content. This study aimed to assess whether changes in BIA raw parameters in dogs with myxomatous mitral valve disease (MMVD) could be linked to disease progression.

Abstract Hazard and operability (HAZOP) analysis is a highly disciplined process hazard analysis (PHA) technique based on the exploration of the effects of process variables deviations. Inconveniences of a conventional HAZOP study are its time-consuming character and high cost. The principal objective of this paper is to present a new methodology for hazard identification of a selected chemical production process. Model-based HAZOP study is a very robust tool for predicting a systems response to deviations from design or operation conditions. An approach based on the mathematical modelling of

Abstract:

Polyhydroxyalkanoates (PHA) are synthesised by bacteria as carbon storage material. The protein PhaG directs carbon from non-related carbon sources such as glycerol, metabolised through fatty acid de novo synthesis (FAS) pathway, with PHA synthesis. The gene that codifies for this protein has not yet been found in the genome of Ralstonia eutropha H16, a model organism. By bioinformatic comparison to already known PhaG proteins, a PhaG-like protein was found codified by gene H16_A0147 and presence of the gene was preliminary confirmed by PCR.

The analysis conducted based on the Dam Safety Report 2020 informs that there are 21953 dams distributed throughout the Brazilian territory registered in National Dam Information System (SNISB). However, 14849 (67.64%) of the dams were not classified as RC and 13475 (61.38%) of the dams were not classified as PHA. There are 3724 dams classified as high PHA, 2407 (64.64%) o
