The escalating demand for efficient transportation infrastructure necessitates the construction of numerous tunnels, particularly in densely populated areas. However, their response to dynamic loads, like earthquakes, remains a critical concern. This study utilizes numerical modeling to assess the dynamic behavior of tunnels embedded in various silty soil types under seismic excitation. Employing Abaqus software and the finite element method, tunnels were modeled within three distinct silty soils: silty stone, silty sand, and low plasticity silty clay. Ground motion data from the 1994 Northridge earthquake was used as input to evaluate tunnel displacements. The results demonstrated significant variations in tunnel behavior based on the surrounding soil. Notably, low plasticity silty clay exhibited the largest displacements, followed by silty sand and silty stone. This emphasizes the crucial influence of soil properties on tunnel stability during seismic events. Future investigations could expand upon this work by incorporating additional soil parameters and utilizing more intricate soil models to yield even more precise predictions of tunnel response under dynamic loading conditions.

The use of mild materials shows an increasing tendency in industrial areas. These materials are also preferred to reduce the unit weight of the building elements in the construction sector. Various light aggregates are used to produce light concrete with a lower density than normal concrete, and the properties of these light aggregates significantly affect the properties of the concrete. In this study, the use of expanded clay aggregate (ECA) produced in the Söğüt region in structural lightweight concrete was examined. Expanded clay, sand, and crushed stone aggregate were used as aggregates in concrete mixtures. The mixture granulometry was kept the same for each group. For this purpose, 60 samples were prepared for a total of 4 mixtures with different contents. Slump and unit volume weight tests were carried out on fresh concrete samples, and compressive, flexural, and splitting tensile strength tests were carried out on 7- and 28-day-hardened concrete samples. Some of the concrete mixture samples were subjected to tests after being kept in the curing pool for 7 days, and some for 28 days. As a result of the experiments, the unit weight and compressive strength values obtained from the samples produced with ECA as coarse and fine aggregate in order to achieve the highest strength target are 1413 kg/m³ and 30 MPa, respectively. The same values were found to be 1652 kg/m³ and 39 MPa in the samples produced with river sand as fine aggregate and ECA as coarse aggregate. In the samples produced using ECA as fine aggregate and crushed stone aggregate as coarse aggregate, these values were also found to be 1689 kg/m³ and 50 MPa.

Floods disrupt essential services and infrastructure including food, utilities and dwellings. These disruptions affect health outcomes and access to essential health services. The increasing incidence of severe weather events has been linked to climate change (IPCC 2022) and highlights the importance of a climate-resilient health system to provide timely services. This paper considers the immediate effects that a severe flooding event within Nepean Blue Mountains Local Health District (NBMLHD) had on emergency health utilisation to inform future health planning and facilitate the evaluation of climate responsive interventions.

Climate change is having a significant effect on disasters worldwide. In response, societies have attempted to mitigate the consequences by developing standardised arrangements, known as incident command systems. Many of these systems have a military heritage using hierarchical command-and-control principles that are authoritative by nature and fit well within bureaucratic organisations. While emergency services agencies have embraced these incident command systems, other agencies have not, thereby making the multi-agency response to disasters challenging. This research investigated current incident command systems to develop an improved framework that includes all agencies and improves the multi-agency response to emergencies and disasters. A multi-modal qualitative research approach was undertaken using a literature review, semi-structured interviews with informants and a policy analysis of recent disaster reviews and inquires. This combined data informed the development of 4 options for improvements to the multi-agency response and consolidated the issues into 5 domains. These domains and options for improvement were presented to a panel of experts at the strategic level of emergency and disaster management by way of a 2-round modified Delphi study. This paper reports on the final phase of the research; the policy analysis and modified Delphi study. The most significant outcome of this research was a new level of understanding of strengths and weakness of the incident command system. This contributed to the development of a new conceptual framework based on modifications to the incident command system principles.

The Gold Coast is a bustling region in South East Queensland with a large concentration of people and has dynamic and growing business and tourism activity. The region is subject to thunderstorms and tropical cyclones that can generate damaging winds. The Severe Wind Hazard Assessment for South East Queensland evaluates the risk posed by severe winds and has strategies for managing this risk (Edwards et al. 2022). Results from the most recent assessment showed that older residential houses were the most damaged by severe winds and that this contributed disproportionately to community risk. However, lessons from recent wind damage caused by Tropical Cyclone Seroja in Western Australia in 2021 indicated that modern house designs have important vulnerabilities. These findings are a concern for any exposed coastal area and, in particular, for South East Queensland. This paper presents a suite of scenarios developed to address this vulnerability. Specifically, we describe how emergency and disaster managers can conduct capability analyses with the goal to enhance intelligence and planning capabilities. An example of the City of Gold Coast was used to show how it has leveraged these capabilities to improve emergency risk-based planning and begin a community resilience transformation with effective places of refuge and evacuation centres for the community.

This study examined the (mis)alignments between multiple disaster cultures, the Indonesia Tsunami Early Warning System (InaTEWS) and local risk profiles as revealed by the 2018 non-tectonic tsunami triggered by the Anak Krakatau Volcanic eruption in Labuan. The research assessed to what extent the tsunami warning system was adapted to local needs and characteristics. Based on qualitative data collection, this study showed that before the 2018 tsunami (and notwithstanding memories of the 1883 Krakatau tsunami) different local groups shared a strikingly homogeneous understanding of tsunamis as exclusively triggered by earthquakes. After the 2018 tsunami, study participants reported increased awareness of different tsunami types and earthquake risks. However, this rarely translated into practical actions and changes at the local level as structural and cultural factors significantly hampered the work of local government and emergency management agencies. This research identified steps to improve alignment, for example by involving community members in warning technology maintenance, tailoring awareness-raising materials to local hazard profiles and connecting awareness-raising with local cultural traditions. However, a reform of the InaTEWS is necessary, including overcoming sectoral silos and incorporating local knowledge and experiences into policymaking. By addressing these (mis)alignments, authorities can better support communities to understand tsunami risks and respond to future event, ultimately enhancing preparedness.

In Australia, the perception of large continental-scale dust storms has traditionally been restricted to aspects of ‘inconvenience’ or ‘novelty’. However, as the climate changes, there is an increased likelihood of dust storm activity that puts communities at increased risk. The aim of this study was to explore the need and possibility of developing a dust early warning system for Australia. Through a scoping review of internationally used sand and dust early warning systems, we found that an array of systems exist or were theoretically tested in the Northern Hemisphere. The sensor networks, one of which was operational, were of particular interest because Australia already has an operational air quality network that could be expanded to a dust early warning system. The need for a trans-boundary system is critical for Australia and, therefore, requires a combined approach of expanded sensor network with satellite-based systems to increase validation of any future modelling approach. This improved understanding could inform the development of a dust warning system for multi-socio-economic factors that account for cumulative exposure to small, localised and large continental-sized dust events.

Avascular Necrosis (AVN), or Osteonecrosis, is characterized by bone tissue death due to insufficient blood supply, prevalent in India with a common occurrence in the femoral head. Ayurveda associates AVN with an imbalance in Vata dosha, presenting symptoms aligning with both traditional and modern medical perspectives. Conventional treatments involve anti-inflammatory drugs and hip replacement, though the latter has limitations. Ayurveda approaches include holistic treatments like herbal medicines and Panchakarma, showcasing potential benefits in symptomatic relief. Modern treatment involves anti-inflammatory drugs and, in severe cases, hip re-placement. The presented case is of a 24-year-old, diagnosed case of grade 4 bilateral AVN of the femoral head who was treated with Panchakarma including Manjisthadi Kshara Basti, Patra pind sweda,pizhichil along with a few Oral Ayurvedic preparations, for 30 days, which provided significant symptomatic relief in pain, improved range of motion and gait. Based on the results, it can be said that panchakarma can provide significant relief in signs and symptoms of Asthimajjagat vat (AVN)

The roots of Shareera (body) existence are Doshas, Dhatus, and Malas. The theory of Tridosha is unique to Ayurveda. These Doshas decide the phenotypic and genotypic character of an individual. They are essential in maintaining the homeostasis of the body. Doshas, when vitiated, can lead to diseases. Vata, Pitta, and Kapha are the Tridoshas with specific Karma (functions) in the body due to their particular Gunas (properties). Among the Tridoshas, Kapha has properties like Shlakshna, Sthira, Guru, Sheeta, etc., which suggest that it is heavy, slimy, thick, and cold. There are five types of Kapha – Avalambaka, Kledaka, Shleshaka, Bodhaka, and Tarpaka. Each of them has its specific location and functions. An attempt is made to understand and correlate Kapha and its subtypes with modern medical science.

As a Saiddhantika Shastra, Ayurveda accepts each theory or principle only after several scientific examinations through Pramana. In This context of the process of Rakta Skandana and Askandana, Panchavayava vakya has been utilised as a part of Anumana Pramana in proving the Process of Rakta Skandana (Blood coagulation). Acharya Sushruta mentioned four Rakta Skandana Upayas to stop excessive bleeding therapeutically. Physiologically, Rakta Skandana will occur through the same sequence of four steps, such as Dahana, Pachana, Skandana and Sadhana. This is proposed with one Drushtanta of the formation of a creamy layer over the surface of milk (Ksheerat santanikavat iva). As Rakta is a vital component, achieving Jeevana or Pranadharana is karma through several properties, among which the process of Skandana and Askandana is one. Therefore, the present work attempts to do the same, which will help us understand the concept and process of Rakta Skandana and Askandana.
