Analytical formulations with experimental validation for determining the incident heat flux from firefronts

Any target exposed to a heat source receives a certain amount of heat flux, depending on the distance, view factor, characteristics of the source, and environmental properties. Incident heat flux is mainly characterized by firefront properties, e.g., flame dimensions, and its thermal attributes by fuel properties, topography, and meteorological factors. Predicting the incident heat flux from the firefronts is crucial for fire risk management and analytical and numerical fire modelling. Based on this specification, safe zones can be defined for elements such as unprotected individuals, firefighters, and buildings. Since the contribution of radiation and convection varies with the fire evolution, it is essential to specify them as a function of distance and slope. This study elaborates determination of radiation and convection for firefronts. Sets of laboratory-scale experiments were conducted using fuel beds of straw with a load of 1.5 kg/m2 on the slopes of 0°, 20°, and 40° measuring the incident radiative and total heat fluxes. The proposed methodology was validated using available approaches and correlations between the flame length and the acceptable safety distance (ASD) were established. Unlike the existing models, a nonlinear correlation between convection and radiation during the firefront evolution is proposed.

Can a new power system help maintain planetary boundaries within a safe operating space?

To meet China's ambitious carbon neutrality target by 2060, the development of a new power system focusing on renewable energy sources such as wind and solar is crucial. This study integrates Planetary Boundaries (PBs) with a life cycle assessment to explore the sustainability impacts of this transformative energy approach both nationally and regionally. Utilizing a GIS-MCDA (Geographic Information System-Multiple Criteria Decision Analysis) model, the analysis covers the period from 2025 to 2060, examining the seven major grid regions in China. Our findings reveal that under current energy production systems, no region can meet its basic energy needs without exceeding petabytes if existing energy production systems are maintained, thereby risking severe PBs transgressions. Simulations indicate that the adoption of the new power system could significantly mitigate these risks. Quantitative results show that, by 2050, the potential reduction in PB pressures could reach up to 30 % at the national level and vary significantly across regions, depending on their specific energy transition strategies. These insights provide a vital scientific basis for future policy-making and optimization of power systems to safeguard environmental thresholds and promote sustainable development in China.

Physiologically Based Biopharmaceutics Modeling for Gefapixant IR Formulation Development and Defining the Bioequivalence Dissolution Safe Space.

Gefapixant is a weakly basic drug which has been formulated as an immediate release tablet for oral administration. A physiologically based biopharmaceutics model (PBBM) was developed based on gefapixant physicochemical properties and clinical pharmacokinetics to aid formulation selection, bioequivalence safe space assessment and dissolution specification settings. In vitro dissolution profiles of different free base and citrate salt formulations were used as an input to the model. The model was validated against the results of independent studies, which included a bioequivalence and a relative bioavailability study, as well as a human ADME study, all meeting acceptance criteria of prediction errors ≤ 20% for both Cmax and AUC. PBBM was also applied to evaluate gastric pH-mediated drug-drug-interaction potential with co-administration of a proton pump inhibitor (PPI), omeprazole. Model results showed good agreement with clinical data in which omeprazole lowered gefapixant exposure for the free base formulation but did not significantly alter gefapixant pharmacokinetics for the citrate based commercial drug product. An extended virtual dissolution bioequivalence safe space was established. Gefapixant drug product batches are anticipated to be bioequivalent with the clinical reference batch when their dissolution is > 80% in 60 minutes. PBBM established a wide dissolution bioequivalence space as part of assuring product quality.

LBTQ parents’ needs for support postpartum following a complicated birth: A matter of reproductive justice

LBTQ people have increased risks of complications during birth, risks potentially driven by minority stress and increased levels of mental illness and fear of childbirth. With the aim of exploring reproductive injustices in postpartum care for LBTQ people, we analyzed qualitative interviews where 22 LBTQ birth and non-birth parents shared their experiences of support needs during the postpartum period after births where complications had arisen. Results point to the importance of providing an LBTQ safe space, which includes the need to feel safe regarding one’s gender or sexual identity, by avoiding cisheteronormative assumptions and using inclusive language. In the context of recently experiencing birth complications, parents needed a space where they were able to focus on physical and mental healing. The results further show the need for validation of the non-birth parent and inclusive breast/chest-feeding support. Results emphasize the need for more psychosocial support around the birth experience, including better medical support and information during the whole process of childbirth.

Žepa- The UN „Safe Zone"

Cyclically for several centuries in Bosnia and Herzegovina, there have been carried out crimes against humanity, serious violations of the Geneve Conventions and violations of the laws and customs of war and other crimes aginst the protected persons and social groups. Crimes are usually committed during armed conflicts. The mass crimes committed in Bosnia and Herzegovina in the previous two centuries were primarily determined by the ideologies of territorial nationalism and the projects for their realisations by the neighbouring Croatia and Serbia. Additionally, in the armed conflict in Bosnia and Herzegovina in the period 1992-1995 numerous crimes against humanity, serious violations of the Geneva Conventios, violations of the laws and costums of war and other crimes against protected objects, in its individual and mass nature, were also committed including the most serious crime that humanity has experienced since its inception- the crime of genocide. The Serbian-Montenegrin aggressor committed numerous forms of crimes against humanity and international law in all occupied towns and cities of the internationally regonised state and and a member of the United Nations (UN). The attacks on the area of the municipality of Rogatica whach are the subject of this research are considered to be the pattern which the aggressor (Federal Republic of Yugoslavia) and its collaborators (Bosnian Serbs) used in order to completely exterminate Bosniaks from the territory of the Republic of Bosnia and Herzegovina which they intended to occupy militarily. The intention and method of committing Serbian crimes in the area of Podrinje, which also included the municipality of Rogatica, during the Greater Serbian aggression in 1992-1995 are the same as the chetnik crimes against the Bosniak population during the World War II. Zepa, the largest of the ten local communities in the municipality of Rogatica, became a small Bosnian enclave during the aggression against the Republic of Bosnia and Herzegovina that resisted the attacks and blows of a far superior enemy until the middle of 1995. Resolution No.824 declaring Zepa a „safe zone” of the United Nations was adopted on May 6, 1993 by the UN Security Council. The aggressor continued the coordinated and systematic „cleansing” of the Bosniak population from that area consciously ignoring the fact that Zepa was declared a „safe zone” by the UN. The attacks on the Bosniaks of Zepa were not of different character compared to the attacks on other areas of the Republic of Bosnia and Herzegovina, especially Podrinje. Attacks on Bosniaks as an ethnic, national, national and religious group as a whole, and therefore those from the area of Zepa, were an integral part of the Greater Serbian ideology, policy and practice of creating the so-called Great Serbia. This research aims to shed light on the importance and status of the UN „safe zone”, the attitude of the international community towards the aggressor and the victims, the aggressor's activities up to the complete occupation of this „safe zone” and the crimes committed against Bosniaks.

Two in one. The norm for safe public space as a ‘guide’ and ‘verification’ of the project

Even today we are faced with a social demand for safer urban spaces. Composition, functional features and management of such spaces are the principles behind a quality and, therefore, safe urban project. However, the orientation to safety and, therefore, to the prevention of those places requires great attention to the structure, organisation and methods of use. The “environmental design” is the perspective, and the application of UNI CEN/TS 14383-2:2023 goes in this direction. A useful tool for the project, this paper highlights the dual function of the Technical Specification, both as a ‘guide’ during the design phase, and as a tool for the ‘verification’ of the project’s final result.

‘Like Solving a Jigsaw Puzzle’: The Role of Journal Writing in Social Work Students’ Professional Development

Abstract Social work education focuses on preparing students for the profession. To this end, many educators utilise reflective journals in their courses. Reflective journaling is recognised in the literature as essential for the construction of students’ professional identity, yet few studies have explored how journals serve this purpose and the specific ways in which journal writing contributes to shaping social workers’ professional identity. This qualitative phenomenological study examined thirty Israeli social work students in their final year of undergraduate studies, before entering the field. Written during a practicum course, their journals were thematically analysed, revealing four themes of journal writing: (i) using personal experiences to construct a professional identity; (ii) acquiring professional concepts and skills by linking theory to practice; (iii) journal writing as professional retrospection; and (iv) journal writing as a safe resonant space for self-development. The discussion elaborates on the significance of each theme for the development of students’ professional identity.

Empowering Women in Biomedical Engineering: A Departmental Pathway to Inclusion and Support

ABSTRACT The underrepresentation of women in science, technology, engineering, and mathematics (STEM) fields, including biomedical engineering, remains a persistent challenge and emphasizes the need for initiatives that attract and retain more women in the field. Such initiatives should address this gender imbalance and aim to harness the diverse perspectives and talents of all genders. Women in engineering face unique challenges due to the field’s male-dominated nature. Gender bias, stereotypes, and family-unfriendly expectations can significantly affect women’s experiences, hindering their opportunities for recognition and career advancement. A 2021 survey of the Biomedical Engineering Department and Graduate Group at the University of California Davis revealed that women and marginalized individuals experience a different sense of belonging compared with their white male counterparts, frequently encounter challenges related to implicit bias, microaggressions, and a lack of adequate support, mentorship, and opportunities for professional development. Here, we describe and reflect on the efforts by the Biomedical Engineering Health, Equity, and Wellness Committee to begin to address these challenges. We launched the Women+ in Biomedical Engineering Lunch Series, which provides a platform for women, marginalized individuals, and their allies to come together, connect, and share experiences. The lunch series aims to facilitate open dialogue, mentorship, and support and promote networking opportunities to bridge the gender gap in the field. The initial meetings in the Spring quarter of 2023 focused on key topics such as mentoring, mental health and stress management, and the effect of legislation on women’s professional lives. By providing a safe space for discussion, sharing experiences, and addressing these topics, the lunch series aims to break down barriers and build networks, foster a supportive environment, and empower women to thrive in biomedical engineering.

Transforaminal posterior lumbar interbody fusion microscopic safe operating area: a three-dimensional model study based on computed tomography imaging

BackgroundEndoscopic spine lumbar interbody fusion (Endo-LIF) is well-regarded within the academic community. However, it presents challenges such as intraoperative disorientation, high rates of nerve damage, a steep learning curve, and prolonged surgical times, often occurring during the creation of the operative channel. Furthermore, the undefined safe operational zones under endoscopy continue to pose risks to surgical safety. We aimed to analyse the anatomical data of Kambin’s triangle via CT imaging to define the parameters of the safe operating area for transforaminal posterior lumbar interbody fusion (TPLIF), providing crucial insights for clinical practice.MethodsWe selected the L4–L5 intervertebral space. Using three-dimensional (3D), we identified Kambin’s triangle and the endocircle within it, and recorded the position of point ‘J’ on the adjacent facet joint as the centre ‘O’ of the circle shifts by angle ‘β.’ The diameter of the inscribed circle ‘d,’ the abduction angle ‘β,’ and the distances ‘L1’ and ‘L2’ were measured from the trephine’s edge to the exiting and traversing nerve roots, respectively.ResultsUsing a trephine with a diameter of 8 mm in TPLIF has a significant safety distance. The safe operating area under the TPLIF microscope was also clarified.ConclusionsThrough CT imaging research, combined with 3D simulation, we identified the anatomical data of the L4–L5 segment Kambin’s triangle, to clarify the safe operation area under TPLIF. We propose a simple and easy positioning method and provide a novel surgical technique to establish working channels faster and reduce nerve damage rates. At the same time, according to this method, the Kambin’s triangle anatomical data of the patient’s lumbar spine diseased segments can be measured through CT 3D reconstruction of the lumbar spine, and individualised preoperative design can be conducted to select the appropriate specifications of visible trephine and supporting tools. This may effectively reduce the learning curve, shorten the time operation time, and improve surgical safety.

Portuguese perspectives for education and inclusion of young forced migrants through sport

ABSTRACT As migratory waves increase and get more complex, social inequalities are likely to arise due to challenges associated with cultural differences, language or lack of supportive networks. Beside international laws and guidelines, responses have been developed for supporting young forced migrants inclusion in host countries. There are suggestions in the literature that sport, if intentionally used as an educational strategy with inclusive purposes, may benefit young forced migrants, not only in terms of their well-being but it may also provide a safe and educational space that allows opportunities for dialogue, language learning and cultural awareness. It is suggested that promoting its practice may create new forms of social, human and cultural capital, leading to meaningful relationships and a sense of (new) belonging. For young forced migrants, sport may become the first motivational asset for engaging with their host community due to familiarity and a common shared language. This article explores Portuguese settlement and inclusion practitioners’ perceptions and uses of sport as an inclusive educational strategy for young forced migrants. Methodologically, the article is based on document analysis of international and national policies and semi-structured interviews with Portuguese actors linked to settlement procedures and sport. The results indicate the existence of policies that aim to protect young forced migrants and acknowledge different challenges concerning their resettlement in Europe. Despite sport being perceived as a valuable educational strategy, particularly in language learning, and an inclusive mechanism for creating a sense of (new) belonging, there are currently limited policies and guidelines in Portugal to implement educational strategies that use sport to include young forced migrants.

Weight, relief and overcoming: a safe space for racialized women learning to swim in Sweden

ABSTRACT This article aims to contribute to the nascent field of critical phenomenology in geography by elaborating on a feminist-phenomenological understanding of the conceptual binary of weight–relief and Nietzsche’s (self)overcoming. These notions provide a theoretical language for the universality of the human condition, transcending the tendency for theoretical-political reification of marginalized subjects’ lives and agencies. The empirical component consists of in-depth interviews with predominantly non-white, immigrant women who have either learned or taught other adult women to swim in a women-only swimming school founded in the multicultural suburb of Fisksätra, Stockholm, Sweden. By historicizing and contextualizing this setting, it is argued that the lack of swimming ability in Sweden (and elsewhere) is today a partly racialized phenomenon, where this deficiency constitutes a socio-phenomenological weight in individuals’ everyday geographies. What this gender-exclusionary space enables, in its quality as a ‘safe space’, is not so much the integration or securing of minority identities as the possibility to overcome one’s own fears and bodily challenges regarding water through shared experiences of safety, convivial solidarity and the joyful pleasures of being-in-water together.

Feasibility and Acceptability of the Novel Tu'Washindi Intervention to Increase PrEP Use among Adolescent Girls and Young Women in Siaya County, Kenya.

The Tu'Washindi intervention addressed intimate partner violence (IPV) and relationship dynamics to increase PrEP use among adolescent girls and young women (AGYW) in Siaya County, Kenya. We evaluated feasibility and acceptability in a cluster-randomized trial in six DREAMS Safe Spaces. The multilevel intervention, delivered over 6 months, included three components delivered by DREAMS staff with support from the study team: an 8-session structured support club; community sensitization of male partners; and a couples PrEP education and health fair ("Buddy Day"). Feasibility and acceptability assessments included implementation process measures, questionnaires, and focus group discussions with AGYWs and post-intervention questionnaires with intervention providers. The study included 103 AGYWs aged 17 to 24 (N = 49 intervention), with 97% retention. Median age was 22, 54% were married, and 84% were mothers. At enrollment, 45% used PrEP and 61% reported lifetime IPV. All intervention participants attended at least one support club session (mean = 5.2 of 8) and 90% attended Buddy Day. At 6 months, most participants perceived Tu'Washindi to be effective: all agreed (with 54% reporting "strongly agree") that the intervention improved partner communication and 60% agreed they were better able to gain partner support for their PrEP use. Providers believed the intervention resonated with community values. Tu'Washindi was highly acceptable and feasible and it was perceived by AGYW participants and providers as being effective in improving partner relationships and supporting PrEP use.

Potential of Ayurveda Therapeutic in Prophylaxis of COVID 19 Pandemic

Now a day the world is go under slightly safe zone of imminent Corona virus (COVID-19) pandemic situation that cause the highly acute respiratory syndrome Corona virus 2 (SARS-CoV-2). Several COVID-19 variants, like Alpha, Delta, Gama, OMICRON and PIROLA, is also causing serious health problems in the world. The diseases have spread throughout the world, with over 774 million confirmed cases and 7.03 million deaths as on March 21, 2024. The pandemic continues to propagate due to the absence of a scientifically validated prophylaxis and therapeutic plan, despite global attempts to eliminate it. The elements of the pandemic require the immediate manipulation of all information system that is globally available. In the treatment of COVID-19 cases, the use of conventional Chinese Medicine in Wuhan provides an indication that conventional health facility will contribute successfully to the cure of these patients. A practical intervention strategy in India is suggested here, based on the Ayurveda classic, recent scientific study and experimental experience in parallel clinical environments. We give a graded response plan, based on the process of infection in a population of individuals. Clinical care is required, despite that’s the fact that no medical frame work also has evidence-based therapy for COVID-19 yet. For the Ayurveda medicine process, therefore, the practical solution proposed here requires immediate implementation. This will temporary learning; it will produce evidence and it will be being a way forward.

A qualitative study on the Virtual Emergency Department care experiences of equity-deserving populations.

Patients from equity-deserving populations, such as those who are from racialized communities, the 2SLGBTQI+ community, who are refugees or immigrants, and/or who have a disability, may experience a unique set of challenges accessing virtual models of care. The objective of this qualitative study was to describe the experiences of patients from equity-deserving communities and their family members who received care from a Virtual Emergency Department (ED) in Toronto, Canada. Forty-three participants (36 patients and 7 family caregivers) with different and intersecting identities who used the Virtual ED participated in the study. Semi-structured interviews were conducted to explore reasons for accessing the Virtual ED, barriers to access, and how the Virtual ED met their care needs and expectations, including ways their experience could have been improved. Thematic analysis was used to identify themes from the data. Patients from equity-deserving populations described negative past experiences with ED in-person care, which included recounts of discrimination or culturally insensitive care while waiting to see the ED physician or nurse. Conversely, participants found the Virtual ED to be a socially and culturally safe space since they could now by-pass the waiting room experience. However, virtual care could not replace in-person care for certain issues (e.g., physical exam), and there was a need for greater promotion of the service to specific communities that might benefit from having access to the Virtual ED. Targeted outreach to help raise awareness of the service to equity-deserving communities is an important future direction.

Assessment of water quality parameters due to longitudinal salinity inundation at Indus Delta: a case study of Kharo Chan, District Sujawal

Deltas are landforms that are formed at the regions where a river meets an ocean. When the freshwater of a river joins the saline water of an ocean, a transitional state of water is obtained. This zone of transition varies on the quantity of freshwater entering the ocean and the quality of both waters. Indus River is facing severe challenges due to climate change which has resulted in reduced water flow in the river. Consequently, seawater intrusion takes place which causes coastal erosion, stunted mangrove growth, and the narrowing of the river towards the seaside. The groundwater in the deltaic regions is unfit for drinking which forces an increased reliance on surface water. Sindh Province of Pakistan, particularly the coastal regions, suffers from severe water quality problems, affecting approximately 41% of the population. The population of this region is deprived of good-quality water for their daily use. This research aims to evaluate the physiochemical parameters of water in the Indus River to identify the zone of salinity inundation and determine safe zones for accessing surface water in the Indus Delta in the Sujawal district. Water samples were collected from Khobar Creek, ending in the Arabian Sea in the areas of Shah Bandar and Kharo Chan at an approximate interval of 5 km. These samples were analyzed for various physical and chemical properties. Properties were compared spatially to develop a relationship between distance and quality of water. Results indicate that the values of dissolved solids in collected samples are between 21,450 and 900 mg/L, pH was between 6.66 and 7.63, conductivity of the samples varied from 33,000 to 1385 µS/cm, acidity values were between 921.14 and 399.84 mg/L, hardness was in the range of 3654 to 192 mg/L, and the turbidity was in between 21 and57 NTU. It was revealed from the results that seawater is having a severe influence upto 15 km from the mouth of the creek in which not a single parameter except the pH was complying with WHO recommendations. In the interval of 15 to 30 km, some properties of water were complying with WHO recommendations, while some of them were deviating from the limits. It has been concluded that turbidity was improving while going toward the ocean, while Total Dissolved Solids, hardness, and chloride concentrations were increasing as water was getting closer to the sea while pH was found almost unaffected. The findings emphasize the need for addressing environmental degradation, social hardships, and economic challenges caused by these water quality issues. Ultimately, the quality of water is crucial for various activities specifically for drinking purposes, and its suitability for specific purposes is of utmost importance.

Virtual reality as an engaging and enjoyable method for delivering emergency clinical simulation training: a prospective, interventional study of medical undergraduates

BackgroundIt is a requirement that medical students are educated in emergencies and feel well prepared for practice as a doctor, yet national surveys show that many students feel underprepared. Virtual reality (VR), combined with 360-degree filming, provides an immersive, realistic, and interactive simulation experience. Unlike conventional in-person simulation, it is scalable with reduced workforce demands. We sought to compare students’ engagement and enjoyment of VR simulation to desktop computer-based simulation.MethodsWe conducted a prospective, interventional, evaluation study. The study was carried out on final year medical students undertaking their Pre-Foundation Assistantship (n = 116) at Imperial College School of Medicine (ICSM) in London. We compared objective engagement, subjective engagement, and subjective enjoyment of VR simulation to desktop computer-based simulation using cardiac arrest and life-threatening asthma scenarios. Engagement was measured objectively using students’ physiological parameters, including heart rate and eye tracking, and facilitator observations using the validated ‘Behavioural Engagement Related to Instruction’ (BERI) protocol. Students’ subjective engagement and enjoyment levels were measured using a post-session survey.ResultsStudents’ maximum heart rates were significantly higher during VR simulation with a mean difference of 4.2 beats per minute (3.2 to 5.2, p < 0.001), and eye tracking showed they spent a significantly greater mean percentage of time of 6.4% (5.1 to 7.7, p < 0.001) focusing on the scenarios in VR compared to standard desktop. Qualitative data showed students enjoyed and felt engaged with the sessions, which provided a safe space for learning.ConclusionsOur study shows that students found VR simulations enjoyable and were more engaged compared to standard desktop simulation. This suggests that 360-degree VR simulation experiences provide students with immersive, realistic training, which is scalable, giving them the unique opportunity to manage emergencies and work within emergency teams, which would not typically occur during traditional training.

A new seven-axis robotic-assisted total hip arthroplasty system improves component positioning: a prospective, randomized, multicenter study

This study compared the radiologic and clinical outcomes of a new seven-axis robotic-assisted total hip arthroplasty (THA) and conventional THA. Hundred and four patients were randomly assigned to two groups—the robotic-assisted THA group (RAS group) and the conventional THA group (CON group). The preoperative and postoperative Harris Hip score (HHS), acetabular inclination, anteversion, femoral offset, and leg length discrepancy (LLD) were compared. During the follow-up, no patients had any complications that could be associated with the use of the robot. The proportion of acetabular cups in the safety zone was significantly higher in the RAS group than that in the CON group. The two groups had significantly different mean absolute difference of inclination and anteversion. There was no significant difference in the postoperative HHSs, changes in HHSs, femoral offset, and lower limb length between the two groups. The seven-axis robotic-assisted THA system is safe and effective, and leads to better acetabulum cup positioning compared to conventional THA. The improvements observed in the HHS, LLD, and femoral offset in the RAS group were similar to those in the CON group.Clinical trial registration time: 19/05/2022.Clinical trial registration number: ChiCTR2200060115.
