Human thermal sensation and its algorithmic modelization under dynamic environmental thermal characteristics of vehicle cabin.

Thermal conditions are strongly changeable in a vehicle cabin, where passengers could suffer consecutive self-thermoregulation to such dynamic changing thermal stresses, though its HVAC system works well. To observe human overall and local thermal sensations in dynamic thermal conditions, a series of experiments under various conditions were carried out in a cabin-like climate chamber. The results showed that the head, chest, back, and hands during hot exposure are warmer leading to the overall thermal sensation being hot. The thermal sensation of the head was warmer than the overall thermal sensation. During cold exposure, arms, hands, legs, and feet were the main areas causing coldness. In a dynamic thermal environment, the previous skin temperature state and thermal sensation form a thermal sensation overshoot, causing a shift in the body's neutral temperature point. This study proposes a thermal sensation model for the prediction of human thermal sensation local and overall based on skin temperature changes in a dynamic environment. Considering the airflow characteristics in the cabin, the human body is set into seven local parts in the local thermal sensation model. To compensate for sensation overshoot from this, defining recovery points rp for local parts differentiate temperature setpoints according to the experienced thermal state so that the effect resulting from the dynamic condition is integrated into the model algorithm. The model provides a scientific basis for guiding design optimization and intelligent regulation in the dynamic environment of the vehicle cabin, so as to achieve efficient energy utilization.

The key regulative parameters in pilot-scale IC reactor for effective incineration landfill leachate treatment: Focus on the process performance and microbial community

Anaerobic digestion is a promising sustainable method for treating highly concentrated organic wastewater from the point of energy recovery. In this study, a pilot-scale internal circulation (IC) reactor was constructed to investigate the key regulative parameters that guaranteed the stable and efficient treatment of incineration leachate. The IC reactor was operated for 77 d by feeding real incineration leachate. With an organic load rate (OLR) of 30 kg/ (m3·d) and an influent pH value of 7.5, the reactor achieved its highest organic removal loading rate (ORLR) and biogas yield of 21 kg/ (m3·d) and 6.3 m3/d, respectively. The kinetic analysis confirmed that the two key parameters that significantly correlated (P < 0.05) with the methane yield and Rmax of sludge were OLR and influent pH value. Key enzyme activity of F420 increased 33.2 % when OLR was raised, but decreased by 5.6 % when influent pH was lowered to 6.8, further demonstrating the need for control over these two operational parameters of IC reactor. High-throughput sequencing results indicated that acetotrophic methanogen Methanosaeta had an overwhelming relative abundance of over 47.2 % in the entire community of all sludge samples. Nevertheless, the enrichment of unclassified_Bacteroidales and Methanobacterium strengthened hydrogenotrophic methanogenesis (HM) with step raise of OLR to 30 kg/ (m3·d), then increased the methane production potential and F420 activity of sludge. This study proposed a referable regulation method for the treatment of the actual landfill leachate via IC reactor.

Double Vision and Light Sensitivity Symptoms are Associated With Return-to-School Timing After Pediatric Concussion.

To determine the association between academic time loss postconcussion and vision symptoms/impairments among pediatric patients. Cross-sectional. Sports medicine clinic. Pediatric patients seen for care in a sports medicine clinic between the ages 6 and 18 years (n = 212; mean age = 14.3, SD = 2.4 years; 48% female) were evaluated within 21 days of concussion (mean = 9.8, SD = 5.7 days). Patients were grouped based on academic time loss (missed >5 days vs ≤5 days of school) at their initial postconcussion evaluation. Patients rated concussion symptoms using the Health and Behavior Inventory (HBI) and underwent near point of convergence (NPC) testing. We compared groups on specific HBI symptom ratings of dizziness, blurry vision, seeing double, and light sensitivity, as well as NPC break and recovery point distances. Two hundred twelve patients were included; n = 36 (17%) who reported missing >5 days of school. After adjusting for time since injury, parental education level, mechanism of injury, and preinjury anxiety, patients who reported missing >5 days of school had higher ratings of double vision (β = 0.27; 95% confidence interval [CI], 0.01-0.53; P = 0.04) and light sensitivity (β = 0.506; 95% CI, 0.061-0.951; P = 0.02), but not dizziness (β = 0.390; 95% CI, -0.047 to 0.827; P = 0.08) or blurry vision (β = 0.026; 95% CI, -0.352 to 0.404; P = 0.89). Missing >5 days of school was associated with worse double vision and light sensitivity symptoms. Given the importance of vision in learning, assessing postconcussion vision symptoms may facilitate a successful return to school. Clinicians should assess a wide spectrum of vision-specific symptoms to ensure appropriate support during the return-to-school process.

Investigation on local geothermal energy attenuation after long-term operation of ground heat exchanger with considering aquifer effect

The long-term operation of deep buried ground heat exchangers (GHE) for heat extraction would attenuate the local geothermal field. The variation of geothermal energy in the affected area over time is a subject worthy of dedicated study. In this paper, the heat transfer between GHE and surrounding geological strata including aquifuge and aquifer layers is modeled and numerically solved to investigate the variations of GHE performance and attenuation behaviors of ground temperature field. The results show that the reduction ratios of GHE performance in the aquifer and aquifuge layers between 1st and 8th years are 1.3% and 8.9%, respectively, due to the convective heat transfer induced by groundwater in the aquifer layer. The analysis of local temperature variation implies that the groundwater flow leads to the circumferential asymmetry of ground temperature reduction in aquifer layer, which also affects the temperature distribution in geological layers adjacent to the aquifer. The worst ground temperature recovery point appears on the borehole wall in the aquifuge layer, while it appears at a fixed position downstream in the aquifer layer. Taking the ground transient and initial temperature difference greater than 0.5°C as the threshold to characterize the attenuation region, the geothermal field attenuation area of the eighth year in the aquifer is about 4.5 times that of the first year, while it is about 5.1 ∼ 5.5 times that of the first year in the aquifuge layers. The analysis of variations of GHE performance and ground temperature field quantitatively evaluates geothermal attenuation behaviors in aquifer and aquifuge layers subject to the long-term operation of GHEs.

Vergence eye movements impairments in schizophrenia and bipolar disorder

One of the most evaluated eye tracking tasks in schizophrenia (SZ) and bipolar disorder (BD) are smooth pursuit eye movements. They rely on the maintenance of slowly moving object on the fovea. While most of the studies evaluated tracking of a target that moves in the fronto-parallel plane, only two assessed vergence eye movements (VEM), which relies on the pursuit of object that moves in depth. The aim of our study was to compare VEM performance in SZ and BD. We evaluated 28 SZ patients, 32 BD patients and 25 healthy controls (HC). Participants underwent thorough optometric examination before eye tracking task. VEM were measured with the use of infrared eye tracker and dedicated vergence stimuli generator. SZ patients showed higher mean break and recovery points of fusion and shorter correct tracking time than HC. BD individuals revealed tracking accuracy deficits and higher number of saccades than HC. Compared to BD, SZ patients showed decrease of maximal convergence and divergence. Moreover, they presented tracking accuracy deficits of non-dominant eye: altered eyes positioning error during convergence and divergence gain. Exploratory analysis revealed significant gender differences between groups in terms of binocular VEM parameters. In this study we have recognized pattern of eye movement disturbances differentiating abovementioned groups. SZ patients showed decreased vergence tracking range with shorter tracking time and impaired accuracy of non-dominant eye, while BD patients showed higher number of saccades with decreased tracking accuracy. Neuroimaging studies are necessary to identify neuronal underpinnings of VEM impairments in SZ and BD.

Pore structure and wetting alteration combine to produce the low salinity effect on oil production

Low salinity water flooding is a promising enhanced oil recovery technique that has been observed, in experiments over a range of scales, to increase oil production by up to 14% in some systems. However, there is still no way of reliably predicting which systems will respond favourably to the technique. This shortcoming is partly because of a relative lack of pore scale observations of low salinity water flooding. This has led to a poor understanding of how mechanisms on the scale of micrometres lead to changes in fluid distribution on the scale of centimetres to reservoir scales. In this work, we use X-ray micro-CT scanning to image unsteady state experiments of tertiary low salinity water flooding in Berea, Castlegate, and Bunter sandstone micro-cores. We observe fluid saturations and characterise the wetting state of samples using imagery of fluid–solid fractional wetting and pore occupancy analysis. In the Berea sample, we observed an additional oil recovery of 3 percentage points during low salinity water flooding, with large volumes of oil displaced from small pores but also re-trapping of mobilised oil in large pores. In the Bunter sandstone, we observed 4 percentage point additional recovery with significant displacement of oil from small pores and no significant retrapping of oil in large pores. However, in the Castlegate sample, we observed just 1 percentage point of additional recovery and relatively small volumes of oil mobilisation. We observe a significant wettability alteration towards more water-wet conditions in the Berea and Bunter sandstones, but no significant alteration in the Castlegate sample. We hypothesise that pore structure, specifically the topology of large pores impacted recovery. We find that poor connectivity of the largest pores in each sample is strongly correlated to additional recovery. This work is the first systematic comparison of the pore scale response to low salinity flooding across multiple sandstone samples. Moreover, it gives the first pore scale insights into the role of pore geometry and topology on the mobilisation of oil during low salinity water flooding.

Heat Integration and Heat Exchanger Network Design with Aspen Energy Analyze

The considerable amount of energy used in industrial processes is typically used for heating and cooling. The synthesis of heat ex-changer networks (HEN) is a critical topic in this industry in order to reduce energy and capital costs in chemical plants. Heating and cooling systems in industry must be designed efficiently, which can be done using technologies like pinch analysis to create an optimal heat recovery network. Heat pinch analysis is a systematic method for designing thermally efficient systems. A designer can determine the minimum heating and cooling requirements as well as the maximum heat recovery (MHR) potential by locating a thermodynamic bottleneck, or the pinch point for heat recovery. This Paper uses Aspen Energy Analyzer for HEN Design.Heat integration network design is a cost-effective strategy that helps industries to cut costs by reducing the number of external utilities needed and increase profitability by lowering energy consumption. The HENs’ composite curves, grand composite curves, grid representation, and target reports were created using the Aspen Energy Analyzer. The software suggested ten designs, which were then optimized based on total annualized cost. By comparing it to other optimized designs, the best design is determined.

Mineralogical Properties of the Copper Slags from the SarCheshmeh Smelter Plant, Iran, in View of Value Recovery

Annually, hundreds of thousands of tons of slags are involved in the reverberator and flash smelting as well as converting operations of Cu-Fe sulfide concentrates to produce matte in the Sar Cheshmeh copper smelter plant, Iran, disposed in the landfill and cooled in air. Due to their relatively high average copper content (about 1.5 wt%), a mineral processing plant based on the flotation process has recently been established to produce thousands of tons of Cu-sulfide concentrate after slag crushing and fine grinding operation. In order to make the flotation process more efficient, more knowledge is required on the form and origin of the copper losses in the slag. To achieve this, mineralogical studies of the slags using optical microscopy, X-ray diffraction (XRD), and scanning electron microscopy (SEM) methods have been carried out. Mineralogical analyses showed the main part of copper losses into the semi- to fully-crystallized magnetite-rich reverberator and flash slags characterized by crystal–glass matrix ratio ≤ 1 is moderate to coarse particles of Cu-Fe sulfides, i.e., chalcopyrite (CuFeS2) and bornite (Cu5FeS4), that are mainly chemically entrapped. In contrast, the mechanically entrapped fine- to coarse-grain (from 20 up to 200 µm) spherical-shaped of high-grade matte particles with chalcocite (Cu2S) composition containing droplets or veinlets of metallic copper (Cu0) are the dominant forms of copper losses into the converter slags characterized by crystal–glass matrix ratio &gt; 1. From the value recovery point of view, our result show that the fully crystallized slags containing moderate- to coarse-grain copper-bearing particles will result in efficient recovery of a significant amount of entrained copper due to better milling response compared to semi-crystallized ones due to locking the fine- to moderate-grain copper particles in the silicate glassy matrix. Laboratory-scale grinding experiments showed that normal (≤74 μm) to fine (≤44 μm) grinding of high- Cu grade slags lead to a significant increase in the liberation degree of copper particles. in contrast, the increase in fine particle fractions (&lt;37 μm) due to re-grinding or ultra-fine grinding of the originally low-Cu grade slags does not lead to the liberation of copper particles, but it will reduce the efficiency of the flotation process. This study suggests that the highest rate of copper recovery of the slag by the flotation process will be obtained at particle size 80% passing 44 µm which has also reached the optimal liberation degree of copper-bearing particles.

Recovery Of Glucose-6-Phosphate But Not ATP Following Fatiguing Skeletal Muscle Contractions In Humans

Intramyocellular ATP depletion can occur during intense muscle contractions if ATP demand exceeds ATP production. If conditions are sufficiently severe, this can lead to a loss of total adenine nucleotides (TAN) in the irreversible step from adenosine monophosphate (AMP) to inosine monophosphate (IMP). The occurrence and bioenergetic implications of ATP depletion during and following intense contractions in vivo are not clear. PURPOSE: To understand the evolution and resolution of changes in vivo in ATP, phosphomonoesters (PME; glucose-6-phosphate (G6P) + IMP), and TAN during fatiguing contractions in humans. METHODS: After providing written informed consent, 9 adults (35 ± 2 yr; 6F) performed 120 maximal isotonic contractions (1 every 2 s) at 20% of peak torque on a non-magnetic knee extension ergometer in a 3 tesla magnetic resonance (MR) system. Phosphorus MR spectra (2-s repetition time) were collected from the vastus lateralis muscle during rest, 4 min of contractions, and 10 min of recovery. Metabolites (ATP; inorganic phosphate, Pi; PME; and phosphocreatine, PCr) were fit using jMRUI and concentrations calculated assuming ATP = 8.2 mM at rest. Standard equations were used to calculate ADP, AMP, IMP and G6P. Statistics: paired t-tests and Pearson correlation. RESULTS: Peak power decreased to 65 ± 17% (mean ± SD) of baseline during contractions (p < 0.01), indicating substantial muscle fatigue. PCr declined rapidly from 32 ± 2 to 7 ± 5 mM (p < 0.01). ATP was maintained during the first 60 s of contractions, then declined steadily to 6.9 ± 0.9 mM (p < 0.01), and was associated with fatigue (r = 0.62 ± 0.3). G6P, ADP, AMP, and IMP increased (p ≤ 0.01, all), and TAN decreased (p < 0.01) throughout the protocol. Intracellular pH fell to 6.72 ± 0.20 (p < 0.01), indicating moderate acidosis. G6P and pH returned to baseline by 10 min recovery, whereas PCr, ATP, IMP and TAN did not (p ≤ 0.01, all). CONCLUSIONS: Intense, dynamic contractions deplete ATP to the point of impaired bioenergetic recovery due to the accumulation of IMP and consequent loss of TAN. In contrast, full recovery of G6P suggests no long-term inhibition of glycolysis under these conditions. The results have important implications for understanding long-duration fatigue and the bioenergetic preparedness of muscle for subsequent bouts of work. Funding: NIH R01-AG058607

Reliability and Resource Allocation and Recovery of Urban Transportation System Considering the Virus Transmission

The urban transport system is an integral part of a city and is essential for the proper functioning of other urban functional systems. To improve the resilience of urban transport systems under the background of the spreading COVID-19 epidemic, this paper predicts the number of patients of various types at each stage of epidemic development based on an improved infectious disease model for Wuhan and verifies the validity of the model using statistical methods. Then, a system reliability model is developed from the perspective of controlling the spread of the virus and reducing economic losses, and the optimal time points for urban traffic closure and recovery are determined. Finally, a resource allocation optimization model was developed to determine the number and location of resource allocation points which based on 19 hospitals to avoid the further spread of the virus. The results give a valuable reference for enhancing the resilience of urban transport systems and improving their performance in all phases.

Changes to Visual Parameters Following Virtual Reality Gameplay.

Introduction:Virtual reality (VR) gameplay is popular with a range of games and educational resources available. However, it puts high demands on the visual system. Current evidence shows conflicting impacts on visual parameters. Therefore, this study explores the changes to vision following VR gameplay.Methods:The study was conducted at the School of Health Sciences, University of Liverpool. All participants had binocular vision with good visual acuity and no manifest strabismus. Participants were assessed before and after playing 15 minutes of the VR game Beat Saber, which incorporated convergence and divergence movements. Clinical assessments including near point of convergence (NPC) and near point of accommodation (NPA) using the RAF rule; accommodative convergence to accommodation (AC/A) ratio; motor fusion using the prism fusion range (at 33cm), accommodation facility using +2.00/–2.00DS flipper lenses, and stereoacuity using the Frisby stereo test were assessed before and after playing.Results:Seventy-eight participants (19–25 years old) were included in the study, with 16 males and 41 females respectively. The breakpoint of convergence reduced by 0.5 cm (p = 0.001). The binocular accommodative facility improved by 2 cycles per minute (cpm); p = 0.004. The mean, near horizontal prism fusion range (PFR) base break and recovery points both worsened by of 5.0 dioptres (p = 0.003), whereas the mean near horizontal PFR base in recovery point improved by of 4.0 dioptres (p = 0.003).Discussion:The study validated previous findings as VR gameplay over-exercised and fatigued convergence muscles, but to a small degree. The VR experience improved the participants’ ability to change focus quickly and improve accommodation, as well as the divergence function of the eye. However, as the participants were retested directly after the VR gameplay, the findings were limited to short term effects on vision.

Survivable virtual network embedding algorithm considering multiple node failure in IIoT environment

The Industrial Internet of Things is a new ecology formed by the deep integration of the Internet of Things and the industrial environment. Network is one of the core technologies of industrial Internet of things. However, in the face of billions of industrial Internet of Things applications, the traditional network architecture cannot meet the needs of these applications for network resources. Network virtualization technology can effectively solve the above problems by decoupling network services from the underlying network. However, the existing heuristic virtual network embedding algorithm is easy to fall into the local optimum, such as the virtual network embedding algorithm based on particle swarm optimization. Therefore, in order to solve the above problems, a virtual network embedding strategy based on the hybrid whale optimization algorithm is proposed. This strategy can avoid the introduction of the population into the local optimum while reducing the amount of calculation. Secondly, a node importance measurement strategy based on weighted aggregation coefficient and traffic prediction is introduced. This strategy can conduct a more reasonable and effective assessment of the importance of nodes. Thirdly, to reduce resource occupation and improve network security and stability, we propose a multi-node failure recovery strategy. It depends on the construction of candidate nodes and the selection of recovery points. Simulation results show that compared with other algorithms, the proposed algorithm reduces the cost and maintains a high success rate of fault recovery. In addition, its request acceptance rate is twice that of other algorithms.

Concurrent 2. Presentation for: Techno-economic evaluation of blue hydrogen production with carbon capture and storage for onshore Eastern Australia

Presented on Tuesday 17 May: Session 2 This techno-economic assessment models the feasibility of a greenfield blue hydrogen development with production capacity of 400 tons of hydrogen per day (TH2/day). At an assumed 85% CO2 recovery rate, the 400 TH2/day production scale equates to a need for approximately 1.241 million tons of CO2 per year (MtCO2/year) of subsurface CO2 storage capacity over an assumed project life of 25 years (approximately 31 Mt of total CO2 sequestered). The blue hydrogen production technology applied to the assessment is a Steam Methane Reformer (SMR) with two points of CO2 recovery (pre-combustion process stream amine scrubbing and post-combustion flue gas capture). The remaining key scope components are the CO2 compression and dehydration system, 65 km of CO2 distribution pipeline and a CO2 injection and storage hub comprised of three injection wells, three deep observation wells and three groundwater monitoring wells. The study includes the screening process applied to identify five high-grade depleted gas reservoirs in the Cooper Basin that are the CO2 storage candidates, and which ultimately define the project location. The economic evaluation of the project includes the definition of cost and operations estimates to determine a mean project case and then applies a Palisade @Risk probabilistic distribution model to key project inputs as to risk the project under various scenarios. The analysis concludes that the economic viability of large-scale, greenfield blue hydrogen projects in Australia is highly dependent on hydrogen sale price, Australian Carbon Credit Unit (ACCU) value, wholesale natural gas prices and capital cost efficiency.

The Impact of Critical Life Points and Events for Survivors of Institutional Child Sexual Abuse: Understanding Trauma and the Role of Compensation in Recovery.

Although the impact of child sexual abuse (CSA) is well documented in the international literature, little is known about the critical points of recovery across the life course for survivors of institutional CSA. The aim of this study was to identify critical points, or events across the life course that may increase, or decrease, a survivor's vulnerability to the complex traumatization of institutional CSA (ICSA). The sample consisted of two hundred and forty-eight witness statements extracted from the 56 publicly available case studies presented to the Australian Royal Commission into Institutional Responses to Child Sexual Abuse during 2013-2016 (Commonwealth of Australia, 2017). A content analysis and thematic coding of the statements identified seven main themes in the witness statements (Gender, Organization, Triggers, Trauma, Mental Health, Intervention and Compensation), that appeared to be critical events across the life course. The themes were transformed into variables for further analysis using SPSS. Significant Likelihood Ratios were found between associations with the organization where the abuse occurred and between triggers and breastfeeding/sensory, breast feeding/childcare, emotional and physical distress, and mental health (p < 0.01). Significant associations were also found between receiving compensation for the CSA and triggers, trauma, breast feeding-sensory and childcare (p < 0.05) and gender and breast feeding (p < 0.05). Overall, the findings showed that triggers can be random across the life course occurring mainly through indirect association, or in situations that evoke memories of the CSA, and that receiving compensation can assist survivors in their recovery journey. The findings also indicate the need for health care professionals to be aware of the critical points in a CSA survivor's recovery and how triggers may impact on their mental welling throughout the life course.

Drought-protective effects of nutrient seed treatments during early growth of oilseed rape

Crop production is increasingly affected by water limitation even in temperate climates due to a rising frequency of drought periods, related with global change. The stress-protective nutrients, discussed as a mitigation strategy, were investigated for their potential drought-protective effects of nutrient seed treatments, based on Ca, K, Fe, Zn, Mn on early growth of oilseed rape (OSR). Responses were observed in five OSR hybrids under greenhouse conditions on two soils with contrasting properties (sandy-loam pH 5.6 vs. silty-loam pH 6.9) in two independent pot experiments. A 7-days drought period with reduced soil moisture level (40% soil water-holding capacity. WHC) inhibited shoot and root growth and caused irreversible wilting and leaf necrosis (27-46% of total leaf area) particularly on the sandy-loam with lower WHC, depending on the investigated genotype. Nutrient seed treatment increased shoot (10-15%) and particularly root growth (14-23%) as well as nutrient accumulation, but also reduced the proportion of irreversibly damaged leaves to 17-21%, with the largest effect in strongly drought-affected genotypes under the challenging conditions on the sandy-loam soil. Analysis of physiological stress indicators revealed increased accumulation of phenolics (23-28%), antioxidants (14-47%) and higher activities of ascorbate peroxidase (APX) (23-87%) in the leaf tissue, counteracting drought-induced oxidative stress. Moreover, APX activity was positively related with root length (R20.8953), suggesting a protective effect on drought-induced oxidative IAA degradation with inhibitory effects on root growth. Increased levels of absisic, jasmonic and salicylic acids during drought stress recovery point to stress priming effects, strengthening the natural adaptive responses to water limitation.

Co-Exploring Meaning in Everyday Life for People in Mental Health Recovery: A Photovoice Study

Research on mental health recovery points to an interdependent relationship between experiences of meaning and experiences of recovery; meaning in everyday life promotes recovery, and recovery promotes meaning in everyday life. In this study we address the following question: What do people with mental challenges find meaningful in their everyday life? To explore this question, we offered disposable cameras to people with mental health challenges and asked them to photograph whatever makes their life meaningful. As part of the collaborative procedure of the study, a competence group contributed to different stages of the research process and the visual data were analyzed by the participants themselves in a participant-driven thematic analysis. Through the analysis the participants constructed seven topics addressing the research question: (1) plants and trees, (2) poems and texts, (3) art, (4) music, (5) going for a walk, (6) esthetics, and (7) public movement. An important methodological implication of the study is how photovoice can be a useful way of generating knowledge from the first-person perspective. The participants’ findings may be interpreted as “small things” that are easily overlooked. When the competence group viewed the participants’ photos, they talked about photos they expected to see but found to be missing. Therefore, we offer a discussion related to the photovoice methodology and suggest the importance of considering absent but expected photographs in such a study.

A Comparison of the Effect of Blast Chilling and Electrical Stunning on Some Hemolymph Parameters in Red Swamp Crayfish (Procambarus Clarkii)

Abstract The aim of the present investigation is to compare the effect of standard method and electrical stunning on some hemolymph biochemical parameters in mid-sized Red Swamp Crayfish. The results showed that electrical stunning time of induction was significantly shorter and recovery was longer than chilling stun. Parameters of an electrical field that stuns crayfish beyond the point of recovery without causing damage have been identified. Based on this experiment, it seems that electrical stunning would be preferable to the other method.

Стратегическое планирование развития рекреационно-туристической сферы Пермского края в условиях ограничений

Development of the tourist and recreational sphere of the country’s regions is one of the points of economic recovery in the post-pandemic period, the importance of which is increasing in terms of stimulating domestic tourism in the country. Perm Krai has the necessary potential to increase its competitive advantages as a center of tourist and recreational services among the regions of the Volga Federal District, since it is consistently among the top three regions in terms of financial and economic indicators of sanatorium treatment. According to expert estimates, this direction will recover at more quickly accompanied by state support measures. However, with the continuing risks of restrictions the need for strategic planning of this activity increases significantly. The article presents the competitive advantages of tourist and recreational industry of Perm Krai. The study used general logical research methods, system and situational approaches, simulation of economic processes. The analysis of the problems of tourism development of Perm Krai is carried out, the limitations and promising directions of its further growth are determined. A model of tasks and solutions for the development of promising tourist territories is presented, which allows to situationally assess the state of tourism in the region, the dynamics and results of its development, as well as make changes to market regulation, if necessary. Further development of scientific research in this area should be associated with the adjustment of existing tools and mechanisms at the regional level to situational problems of the functioning of tourist and recreational industry of Perm Krai. The formation of a cluster framework of territories should be organically combined with support measures in conditions of restrictions, which may subsidies and compensation for labor costs, preferential loans, tax holidays.

Experiences of Being Cared-For: The Perspective of an Expert-by-Experience in Mental Health.

It is difficult to understand what it feels like for people with mental ill-health to be cared-for and supported by family members; this experience is often little-explored. Narratives about caring have been increasingly written alongside first-person accounts of recovery, however, there is a dearth of literature written to gain the perspective of being cared-for because of mental distress. Thus, using autoethnography, I present three critical incidents occurring at different points in my recovery to enable exploration of experiences of being cared-for. Firstly, a critical incident at the point of acute unwellness is introduced, secondly an incident during a consultation with a health professional is highlighted, and finally a moment of transition when embarking on an independent life with my husband-to-be is described. I use autoethnography to connect “the autobiographical and personal to the cultural, social, and political”. I consider how the identity of a carer is continually negotiated in a relationship with the service user in both the “private” and the “public” worlds during recovery. I reflect on how professionals can support both service users and carers in a triangle of care, by providing information and support, alongside promoting the development of independence and agency for the service user whilst in the caring relationship. Finally, I introduce a service model which promotes a family network approach to empower the service user, and highlight training programs on recovery that enable carers. I conclude by suggesting the potential of both approaches to support carers to promote the recovery of the service user.
