The Effect of Exam Stress on Age Dynamics of Vegetative Indicators of Choleric Students

The aim was to find out the effect of the higher nervous activity on the post-exam autonomic nervous system indicators during the emotional stress of the exam process in students with a choleric temperament type of the age limit of 17 (1st year). Physiological indicators of different states of excitement and temperament type were first studied in the experiment. In order to comprehensively assess the effect of emotional stress on students of different ages and courses, we measured arterial pressure and the number of heart beats per minute, which are the main hemodynamic indicators. The research was conducted 2 months before the exam, 30 minutes before the exam and 30 minutes after the exam. Before starting the research, the temperament types of the young people were studied after the nervous examination. The situational anxiety of young people with different temperament types was determined by post-test scores in three different situations: on regular days, before the exam and after the exam. The results of the conducted research show that there are differences in the activity of the autonomic nervous system in students of different ages. The analysis of the results of the hemodynamic changes that we obtained from the effect of exam stress on groups also shows that the autonomic index of the credo is in a state of dominance of the sympathetic tone on an ordinary day and before the exam. The characteristics of the autonomic nervous system after the exam have a direct effect on the adaptation of a person. An increase in the level of the agitation process caused by one or another influence of ASF temperament types indicates the exacerbation of the credo's vegetative index in all groups. An increase in the level of excitement correlates with an increase in the activity indicators of the sympathetic branch of the autonomic nervous system.

The role of vertical grid resolution and turbulent diffusion uncertainty on chemical transport modeling

Chemical transport models (CTM) tend to perform poorly in simulating pollution processes under weak turbulent diffusion conditions. In this study, we address this issue from the perspectives of vertical grid resolution and vertical mixing schemes. Three vertical grid resolution configurations (L4, L12, L40) with the CHIMERE model are evaluated during a winter episode, which includes a heavy pollution episode (PE) in the Paris region. The results emphasize the significance of vertical grid resolution, particularly noticeable during nighttime, and consequently impacts CHIMERE simulations under nocturnal stable conditions. Consistent improvement in CTM modeling is observed with refined vertical resolutions and the first layer height based on a simple linear vertical diffusion scheme defined as the initial Kz diffusion (IKD) scheme. Compared to the other two configurations, the finest configuration (referred to as L4-IKD) demonstrates an average improvement in root mean square error of 23.26 % and 25.09 % on regular days (RD) and 62 % and 129 % during PE, respectively. However, simulations using the 1.5-order turbulence kinetic energy (TKE) based eddy diffusivity closure scheme, named the new eddy diffusion (NED), are more sensitive to the first layer height setup. Excessively fine first-layer heights can lead to inaccurate TKE calculations. Generally, models with low vertical grid resolution can reasonably predict air quality on RD or during light pollution events but struggle with heavy PEs. One straightforward enhancement strategy involves adding an extra fine first layer height in CTM simulations, resulting in an average 50.10 % improvement from L4-IKD to L12-IKD during PE. Another strategy is enhancing the model's vertical diffusion scheme, which improved the CTM modeling by 26.67 % compared with IKD during PE under identical vertical grid resolution.

A Comparative Study on the Impact of Fasting on Blood Glucose and Blood Pressure Among Diabetic and Non-Diabetic Individuals During Ramadan, Kurdistan Region, Iraq

Objective: The primary aim of this research was to evaluate the differential effects of regular and fasting dietary patterns on blood glucose levels and blood pressure among diabetic patients and non-diabetic control group. A comprehensive analysis was conducted to compare physiological responses on fasting versus non-fasting days during the holy Ramadan month. Methods: This observational study involved 92 participants, with a subset of 38 diabetic patients and 54 non-diabetic control group, aged 19-76 years, who were observed on regular and fasting days. Participants were monitored for pre-prandial, postprandial, evening blood sugar, and fasting blood glucose levels, as well as blood pressure. Statistical analysis was performed using paired sample t-tests to compare mean ± SD between regular and fasting days of both groups. The study cohort consisted of male and female adults diagnosed with type 1 or type 2 diabetes. Exclusion criteria included individuals under 18 years, pregnant women, and patients unable to fast during the study period. Results: Statistical analysis revealed significant differences in fasting blood glucose levels during Ramadan compared to non-fasting days. In the diabetic group, significant changes were observed in fasting blood glucose levels during Ramadan compared to after Ramadan ( postprandial blood sugar p=0.04, evening blood sugar p=0.019). In contrast, the non-diabetic group also showed significant changes in blood glucose levels during Ramadan compared to after Ramadan (postprandial blood sugar p=0.001, evening blood sugar p=0.020). Blood pressure showed no significant differences between these periods, suggesting that fasting does not alter blood pressure significantly in diabetic individuals. Additionally, a two-way ANOVA demonstrated significant dietary influences on post-Iftar glucose levels in non-diabetics (p<0.001), but not in diabetics, suggesting differential metabolic responses to dietary intake during Ramadan. These findings emphasize the critical need for personalized dietary management and continuous monitoring to optimize diabetic care during fasting. Conclusion: Fasting significantly influences blood glucose levels in diabeticand non-diabetic individuals but does not affect blood pressure. This study underscores the necessity for personalized medical guidance and balanced meal planning to minimize complications and enhance diabetes management during fasting. Further research is warranted to explore the long-term effects of different fasting practices on diabetic health outcomes.

A Collision Risk Assessment Method for Aircraft on the Apron Based on Petri Nets

The airport apron is a high-risk area for aircraft collisions due to its heavy operational load and high aircraft density. Currently, existing quantitative models for apron collision risk provide limited consideration and classification of risk areas. In response, this paper proposes a Petri net-based method for assessing aircraft collision risk. The method predicts the probability of aircraft reaching different areas at different times based on operational data, enabling the calculation of collision risks within the Petri net framework. This approach highlights areas with potential collision risks and provides a classification evaluation. Subsequently, aircraft path re-planning is carried out to reduce collision risks. The model simplifies the complex operations of the apron system, making the calculation process clearer. The results show that, during the mid-phase of aircraft taxiing, there is a significant deviation between the actual and ideal positions of aircraft. Areas with high taxiway occupancy are more prone to collision risks. On peak days, due to relatively high flight volumes, the frequency of collision risks is 14% higher than on regular days, with an average risk increase of 23.3%, and the risks are more concentrated. Therefore, reducing collision risks through path planning becomes more challenging. It is recommended to focus attention on areas with high taxiway occupancy during peak periods and carefully plan routes to ensure apron safety.

Developing a Supportive Community of Practice

This paper employs a qualitative case study to suggest how the research journey of doctoral students can be improved in educational institutions by encouraging the formation of small and informal Communities of Practice (CoP). It examines themes emerging from the feelings and opinions of four part-time professional doctorate students about their study experience and participation in their emergent CoP. A peer group developed where the students share their experience, expertise, insight, and knowledge in a caring and supportive, but informal, forum. CoP could become an effective tool to aid retention, identity development and wellbeing of postgraduate level students, factors which have been previously identified as key areas of risk. An autoethnographic approach was used to review the feelings, perceptions, and opinions of the four case study group members about their experiences of the informal CoP to date. Thematic analysis of transcripts and WhatsApp communications was used to reveal the perceived common benefits and gains from participation in the informal CoP such as joy, safe spaces, and identity development, aligning members experiences to a CoP lifecycle. The study found small group formation at doctoral programme induction, and encouragement for students to organise their own regular study days using of social channels, may impact overall success. Application and adaptation of this doctoral CoP model could form the basis for future research and a model for academic institutions to suggest to new and existing students

Traumatic Dental Injuries: Prevalence, First Aid, and Mouthguard Use in a Sample of Italian Kickboxing Athletes.

Traumatic dental injuries (TDIs) are a common complication in sports, with an overall prevalence ranging from 0.71% to 60%. Kickboxing is a high-risk combat sport for trauma to the facial region. A total of 142 5-to-65-year-old amateur athletes participated in the survey with a questionnaire that was released during their regular practice days. The questionnaire was structured into three parts: (1) questions about age, gender, type, and time of sports practice; (2) questions about dental injuries, personal experience, and awareness of emergency management, particularly about tooth avulsion; (3) questions about wearing a mouthguard for TDI prevention. A total of 13 percent of athletes suffered a TDI while training or fighting. Regarding first aid, 61% of the participants in this survey are aware of the possibility of replanting a tooth after its avulsion; 10% believe that the tooth should be replanted within 15 min, and 37% of athletes believe that it should be kept wet. The mouthguard is known to the majority of athletes (94%), and 66% were informed by the coach; 68% of the athletes use it. Seventy-four percent of the mouthguards were purchased in a sports shop. A relatively low prevalence of TDIs was observed in players in the sample. A lack of information about the emergency management of tooth avulsion and about the type of mouthguard to wear emphasizes the importance of educational training by dentists to athletes and coaches.

No need for meat as most customers do not leave canteens on Veggie Days

Switching to a diet lower in red meat has the potential to reduce greenhouse gas emissions. Using a unique time series of daily sales data from three German university canteens from 2017 to 2019, we analyse the effects of a monthly Veggie Day in a food-away-from-home context. We find that the temporary ban on meat dishes did not lead to a widespread boycott – as the heated public debates might have suggested. In our setting, a Veggie Day could reduce greenhouse gas emissions by up to 66%. However, especially at the site with a higher share of meat eaters on regular days, up to 22% of customers bypassed the meat-free main dishes on Veggie Days and ate at other on-site alternatives where meat was available. However, total on-site sales did not decrease significantly. Students were less likely to switch to alternatives than staff and guests. A less stringent implementation of a Veggie Day where only beef dishes were removed from the menu, did not result in a significant shift to alternatives but could reduce emissions by up to 51%.

PSIX-28 Optimization of feeding trial length for evaluating feed efficiency in sheep

Abstract Feed efficiency tests are well established for beef cattle, but testing for sheep remains rare due to the lack of appropriate equipment and standardized protocols. To explore the optimum trial length for evaluating feed efficiency in sheep, freshly weaned Rideau Arcott ewe lambs [n = 80; 4to 5 mo of age and body weights (BW) of 16 to 25 kg] were enrolled in a 65-d feeding trial, following a 20-d adaptation period. A mixed ration containing barley gain and protein supplement pellets were offered twice daily, and lambs had ad libitum access to feed, water and bedding straw during the trial period. Daily feed intake of individual lambs was monitored with Vytelle SENSE feed bunks, BW was recorded biweekly, as well as on two consecutive days at the start and end of the trial. Lambs that had died or had abnormal growth patterns from sickness were removed, resulting in 62 lambs remaining in the final dataset. Optimum trial length for measuring feed intake (DMI) and average daily gain (ADG) were evaluated with R Software (v. 4.3.3) via a post-hoc analysis of constructing shortened trial lengths from the regular test. The DMI and ADG values from the shortened trial datasets were compared with those from regular trial days with correlation (Pearson and Spearman tests) and linear regression analyses. There were 64 shortened trial lengths for DMI by 1 d increments, and 15 sub-datasets for ADG consisting of trial lengths between every two BW measurements. Residual feed intake (RFI), residual average daily gain (RADG), and residual intake and BW gain (RIG) were calculated for and compared between the regular trial length (65 d) and favorable shortened trial lengths based on DMI and ADG evaluations. Correlation, regression and agreement analyses were used to determine the optimum trial lengths for RFI, RADG and RIG evaluations. Results showed that DMI and ADG measurements could be shortened to 42 (r > 0.95, R2 > 0.90, β > 0.95, P < 0.001) and 56 d (r > 0.96, R2 > 0.93, β > 0.96, P < 0.001), respectively. Additionally, trial length for RFI, RADG, and RG evaluations could be reduced to 56 d (r > 0.95, R2 > 0.91, β > 0.95, CCC > 0.95, P < 0.001), primarily due to the trial length requirement for accurate ADG measurement. Reducing the duration of trials for evaluating feed efficiency in sheep not only reduces testing costs, fostering greater uptake among sheep producers, but also allows for the evaluation of more lambs annually, thereby enhancing the overall productivity and profitability of the sheep industry.

Exposure to ultrafine particles, black carbon and particulate matter during commute in a suburb from the Yangtze River Delta, China

This study evaluated the exposure of commuters to particulate matter (PM), black carbon (BC), and ultrafine particulate matter (UFP) concentrations in five different traffic microenvironments (bike, bus, taxi, electric motorbike, and subway) under various conditions, such as regular and dust days, weekdays and weekends, and peak and off-peak commute hours in Nanjing, China. In the morning peak hours, bicycle commuters were exposed to the highest PM concentration, those on buses to the highest BC concentration (3.4 ± 3.0 μg/m3), and those on buses and taxis to the highest UFP number concentration. Throughout the rides, the commuter on the subway had the lowest mean exposure concentration of PM, BC, and UFP number. Bicycle commuters (16.25 μg/km) had the highest total inhaled dose of PM2.5, followed by e-bikers (1.98 μg/km), bus riders (1.28 μg/km), taxi riders (0.69 μg/km), and subway users (0.45 μg/km). Weekday PM2.5 exposure levels (115 μg/m3) and BC exposure levels (1.8 μg/m3) were higher than weekend levels (170% and 158%, respectively). The mean exposure concentration of PM10 (1299 ± 1286 μg/m3) in the evening peak of dust days was 803% and 994% higher than the mean concentrations on weekdays and holidays, respectively. PM2.5, PM10, and BC concentrations on dust days were significantly higher than those on weekdays and holidays. The overall mean ratios of PM1/PM2.5 and PM2.5/PM10 were 0.47 and 0.36, respectively, and the five commuting microenvironments had higher proportions of 2.5–10 μm and 1–2.5 μm particles in PM10 and PM2.5, respectively. Reducing the sources of particulate matter in the corresponding particle size ranges could lower exposure levels.

Vegetation reduces cooling demand in low-income neighborhoods on hot days in Chicago

Cooling energy demand is sensitive to urban form and socioeconomic characteristics of cities. Climate change will impact how these characteristics influence cooling demand. We use random forest machine learning methods to analyze the sensitivity of cooling demand in Chicago, IL, to weather, vegetation, building type, socioeconomic, and control variables by dividing census tracts of the city into four groups: below-Q1 income–hot days; above-Q1 income–hot days; below-Q1 income–regular days; and above-Q1 income–regular days. Below-Q1 census tracts experienced an increase in cooling demand on hot days while above-Q1 census tracts did not see an increase in demand. Weather (i.e. heat index and wind speed) and control variables (i.e. month of year, holidays and weekends) unsurprisingly had the most influence on cooling demand. Among the variables of interest, vegetation was associated with reduced cooling demand for below-Q1 income on hot days and increased cooling demand for below-Q1 income on regular days. In above-Q1 income census tracts building type was the most closely associated non-weather or control variable with cooling demand. The sensitivity of cooling demand for below-Q1 income census tracts to vegetation on hot days suggests vegetation could become more important for keeping cities cool for low-income populations as global temperatures increase. This result further highlights the importance of considering environmental justice in urban design.

Local hydroclimate drives differential warming rates between regular summer days and extreme hot days in the Northern Hemisphere

In this work, we compare the rate of warming of summertime extreme temperatures (summer maximum value of daily maximum temperature; TXx) relative to the local mean (summer mean daily maximum temperature; TXm) over the Northern Hemisphere in observations and one set of large ensemble (LE) simulations. During the 1979–2021 historical period, observations and simulations show robust warming trends in both TXm and TXx almost everywhere in the Northern Hemisphere, except over the eastern U.S. where observations show a slight cooling trend in TXx, which may be a manifestation of internal variability. We find that the observed warming rate in TXx is significantly smaller than in TXm in North Africa, western North America, Siberia, and Eastern Asia, whereas the warming rate in TXx is significantly larger over the Eastern U.S., the U.K., and Northwestern Europe. This observed geographical pattern is successfully reproduced by the vast majority of the LE members over the historical period, and is persistent (although less intense) in future climate projections over the 2051–2100 period. We also find that these relative warming patterns are mostly driven by the local hydroclimate conditions. TXx warms slower than TXm in the hyper-arid, arid, semi-arid and moist regions, where trends in the partitioning of the turbulent surface fluxes between the latent and sensible heat flux are similar during regular and extreme hot days. In contrast, TXx warms faster than TXm in dry-subhumid regions where trends in the partitioning of the surface fluxes are significantly different between regular and extreme hot days, with a larger role of sensible heat flux during the extreme hot days.

Analysis of the Multi-Dimensional Characteristics of City Weather Forecast Page Views and the Spatiotemporal Characteristics of Meteorological Disaster Warnings in China

In order to provide insights into how various page views are influenced by public engagement with weather information and to shed light on the patterns of warning issuance across different seasons and regions, this study analyzes the multi-dimensional characteristics of city weather forecast page views and the spatiotemporal characteristics of early warning information in China, from 1 March 2020 to 31 August 2023. This is achieved by utilizing the daily page views of city weather forecasts and meteorological warning data, comparing the public’s attention to weather during holidays versus regular days, assessing the public’s attention to weather under different meteorological warning levels, and performing statistical analysis of the spatiotemporal scale of meteorological disasters. Our analysis shows that compared to weekends and holidays, the public pays more attention to the weather on weekdays, and the difference between weekdays and national statutory holidays is more significant. Due to the widespread impact of heat waves, typhoons, severe convective weather, and geological disasters caused by heavy rainfall, public awareness and participation in flood season weather forecasting have significantly increased. Under red alerts, flash floods, typhoons, and geological risks are the primary concerns. Orange alerts predominantly feature flash floods, rainstorms, typhoons, snowstorms, and cold waves, while sandstorms attract the most attention during yellow alerts. Droughts, however, receive relatively less attention regardless of the warning level. Seasonal patterns in the issuance of meteorological warnings reveal a peak in summer, particularly with typhoons and rainstorms being the main concerns in July, followed by high temperatures and additional typhoon warnings in August. Heavy sea surface wind warnings exhibit a strong seasonal trend, with the majority issued during the winter months. Regionally, southern China experiences the highest frequency of severe convection weather warnings, with provinces such as Jiangxi, Guangxi, and Hunan being the most affected.

CENTRAL AORTIC PRESSURE (CAP) MEASURED IN THE OFFICE WITH SPHYGMOCOR AND DURING 24 HOURS (MOBIL-O-GRAPH AND ARTERIOGRAPH) AND HYPERTENSION MEDIATED ORGAN DAMAGE (HMOD) IN YOUNG PAT

Objective: Central aortic pressure (CAP) is a parameter of central hemodynamics. It can be measured in the office with SphygmoCor, and during 24-hours with Mobil-O-Graph and Arteriograph. Debate is going on whether CAP is more associated with HMOD than brachial blood pressure. The aim of our study is to analyse assocation of office CAP and 24-hour CAP with HMOD in patients with stage 1 hypertension. Design and method: This study included 154 patients with the primary hypertension (69.5% women, mean age 38.5). In all of them we collected various clincial data and antroplogical paramaters. CAP was measured in the office (SphygmoCor) and during regular working days (24h ABPM systems: Mobil-o-Graph and Arteriograph). Results: The increased office CAP was associated with five indicators of HMOD: decrease in eGFR, increase in 24 hours albuminuria, thickness of the intima and carotid media (cIMT), NT pro-BNP, left ventricular hypertrophy- ECG Cornell criteria (LVH). Elevated 24-hour (Mobi-O-Graph) systolic CAP was associated with increased cITM and decreased EF. Higher values of diastolic CAP (Mobi-O-Graph) were accompanied by a greater possibility of LVH. An increase in 24 hours systolic CAP (Arteriograph) was followed with an increase in the cITM. An increase in 24 hours diastolic CAP(Arteriograph) was followed with a decrease in eGFR. Conclusions: CAP could be considered as a indicator of HMOD and total cardiovascular risk especially in young patients, but large longitudinal studies are need in order to confirm this. CAP measured with SphymoCor can be considered a better predictor of HMOD compared to CAP measured over 24 hours. Further investigation is needed to determine clinical value of both office and 24 hours CAP.

Rigid bronchoscopy: a consultant survey.

Inhalation of foreign bodies represents a potentially fatal emergency in both adults and children. Chest x-ray, in isolation, is neither sensitive nor specific. Rigid bronchoscopy represents the gold standard to diagnose and retrieve paediatric foreign bodies. Cases are encountered infrequently, creating anxieties about their management. Little is known about the confidence in, and maintenance of, rigid bronchoscopy skills by ear, nose and throat teams. A 15-question survey was completed by 50 practising otolaryngology consultants in England. Results show that almost 40% of otolaryngology consultants covering rigid bronchoscopy have not performed bronchoscopy in more than 5 years. Consultants raised concerns about the anaesthetic support and the speed of equipment assembly. Questions on clinical practice showed disparities in practice in the same scenario. The authors advocate addressing many of the issues raised by the study with a greater availability of simulation courses and regular scheduled intradepartmental teaching days for all professionals involved. National guidelines on criteria for transfer to tertiary centres would improve the consistency of practice.

코로나 19 팬데믹 기간과 그 이전의 중 고등학생 정서문제 잠재전이유형 비교

This study analyzed the latent profile and latent profile transition of middle and high school students during and before the COVID-19 pandemic. The aim was to identify and characterize the latent profile of emotional problems among middle and high school students and to examine the transfer between latent groups. To do so, we utilized data from the third and fourth years of the Child and Adolescent Panel 2018 (Middle 1 Panel) and the sixth and seventh years of the Child and Adolescent Panel 2010 (Elementary 4 Panel). As a result of the analysis, first, during COVID-19, the profiles of emotional problem were categorized into five groups for middle school students and four groups for high school students. Second, the pre-COVID-19 emotional problem profiles were equally categorized into four groups of middle school and high school students. Third, the classification of potential profiles is noteworthy for the “Attention Deficit-Aggression Hyperactivity” group during the corona period. In 2020, due to the pandemic, middle school students did not attend school for the majority of the regular school days, creating a group that was not present at any other point in time, as they were unable to learn the daily routine of school and were unable to be sanctioned for attention. Fourth, before the COVID-19 pandemic, the transition type of the emotional problem profile showed a transition to a stable emotional group as students entered high school, but during the pandemic, there was a notable shift, with transitions in emotions, including transitions from the 'emotional risk group' to the 'emotional stability group' and vice versa.

Change of Vegetative Indicators Due to the Influence of Emotional Tension of the Examination Process in 21-year-old Students With Choleric Type

One of the factors causing stress in society is exam stress. Taking exams is stressful and quite exciting in itself. However, under the influence of excitement, the student cannot show his little knowledge. From this point of view, the study of psychological and physiological development of students is also of special importance. The study is dedicated to the change of vegetative indicators due to the influence of the exam process depending on the temperament of the nervous system in students of the 5th year of choleric type. In this regard, the main goal of the study was to reveal the age characteristics of changes in vegetative indicators depending on the type of temperament as a result of the effect of emotional stress during the examination. In order to study the effect of the exam process on emotional stress, students were divided into three groups: The first group was students studying on regular school days 2 months before the exam, the second group was 30 minutes before the exam process, and the third group was the group after the exam and 30 minutes after the exam process. First of all, the physiological indicators of different states of excitement of the temperament type and the process of excitement were studied in the experiment. In order to comprehensively evaluate the effect of emotional stress, we measured the main hemodynamic parameters, arterial pressure and number of heart beats per minute. It was determined that, depending on the type of temperament, vegetative indicators before the exam process (heart pressure, systolic and diastolic pressure) of young people on an ordinary day, before and after the exam, are different. However, after the exam, these indicators do not fully return to the norm. The tone of the sympathetic nervous system prevails during the examination process in all age groups.

Assessment of ambient air quality in relation to the burning of firecrackers during the festival of Diwali: A case study of Jodhpur City (India).

The study attempts to examine the impact of firework activities during Diwali Festival on ambient air quality of Jodhpur city. Air quality parameters particulate matter of diameter 10μm (PM10), particulate matter of diameter 2.5μm (PM2.5), sulfur dioxide (SO2), nitrogen dioxide (NO2) and heavy metals in PM2.5 like Pb, Ni, Ba, Al, As and Sr are monitored at two locations, for 15days, starting from 7days before the festival of Diwali, on the day of the festival (Diwali) and 7days after Diwali. On the occasion of Diwali, it was discovered that the 24-h average levels of various pollutants were significantly elevated compared to regular days preceding the festival. Specifically, at the HBO site, the concentrations were notably increased, with sulfur dioxide (SO2) reaching 5.62 times higher, nitrogen dioxide (NO2) at 3 times higher, particulate matter of diameter 10μm (PM10) at 2.35 times higher, and particulate matter of diameter 2.5μm (PM2.5) at 1.01 times higher than the usual levels before Diwali. Similarly, at the PTMM site, there were substantial elevations in pollutant concentrations during Diwali compared to pre-festival days, with SO2 registering 2.53 times higher, NO2 at 2.37 times higher, PM2.5 at 1.9 times higher, and PM10 at 1.57 times higher levels than normal. Concentration of Al, Ba, Sr and Pb at HBO site and Al at PTMM site was highest on Diwali day. Air quality index which was in good category on normal days before Diwali, fell into poor category starting from the day before Diwali and remain in poor category on normal days after Diwali. The result indicates the worsening of ambient air quality during Diwali which can adversely impact the human health in terms of various respiratory complications.

ÇAVDAR TARLASINDAKİ ÇOCUKLAR ROMANINDA SAHTEKARLAR VE SAHTELİK

The Catcher in the Rye, American writer Jerome David Salinger’s sole novel written at the very beginning of the second half of the 20th century, soon after its release, created reactions with its theme, language, and the mass it appealed to. The element that the novel owes its enduring popularity to, even observable today, is the fact that American teenagers found themselves in the novel, and claimed the protagonist reflects their own inner worlds and their point of view against society just as a mirror. The novel's protagonist, Holden Caulfield, is described as a rebellious adolescent alienated from people around him, especially the adults’ world. He is ultimately inclined to run away from society because of the sense of phoniness he feels in the acts and thoughts of those people in almost every moment of his regular days. This paper will analyze the theme of the phoniness of the adult world by comparing the period depicted in the novel with modern Turkish society. This will be done through various questions concerning quotes from the novel and commentary on these quotes, highlighting the universal and timeless nature of Salinger’s work. By examining both literary and sociological perspectives, the study aims to contribute to a deeper understanding of The Catcher in the Rye.

Dynamic Assessment of Urban Carrying Capacity Load Number Using the Enhanced UCCLN Model

The sustainability of cities often changes as rapid urban developments and population growth affect the carrying capacity. Understanding the dynamics of carrying capacity becomes crucial for tourist-oriented cities. This study focused on Baguio City, the “Summer Capital of the Philippines”, attracting large crowds on holidays and actively promoting various events on other days, thus having temporal context variations classified as regular days, days with events, and holidays. Using the enhanced urban carrying capacity load number (EUCCLN) model, the changes in the load number (LN) are calculated for different temporal contexts based on spatial indicators grouped into air, traffic, economy and waste. The city experiences the worst pressures on air quality during holidays, with 99.23% of the districts at very high to critical levels, followed by regular days and days with events. However, the total LN during holidays is balanced by favorable economic conditions with only 9.23% of the districts at the critical level. EUCCLN effectively pinpoints areas that are at critical states at any given time, advocating targeted government monitoring. We demonstrate that nighttime light, for places with no available economic data, can be used as a proxy to highlight areas requiring improved urban vibrancy. This work suggests that monitoring urban pressures using EUCCLN can easily be extended to real time with nowcasting indicator data.
