Temporary Closure

In the second half of the nineteenth century, the nature of the national policy of Russia is significantly changing. After the events of 1863 in Poland (the Second Polish uprising), the government of Alexander II gradually abandoned the dominant idea of ​​anathematizing, whose essence is expressed in the domination of the principle of serving the state, the greatness of the empire. The tsar-reformer deliberately changes the policy of etatamism into the policy of state ethnocentrism. The manifestation of such a change is a ban on teaching in Polish (1869) and the temporary closure of the University of Warsaw. At the end of the 60s, the state's policy towards a five million Russian Jewry was radically revised. The process of abolition of restrictions on travel, education, place of residence initiated by Nicholas I, was provided reverse.

Dayasari residential college building was designed with the internal courtyard that allows for numerous implementations of bioclimatic design strategies, especially on daylighting. The field measurement was conducted at eight unoccupied student rooms, selected as samples to represent ten scenarios and orientations that concerned with the level of radiation and penetration of sunlight. This study reveals the contribution of the internal courtyard in the residential college which allows the daylight penetration at the corridor areas and interior of the rooms through the transom over the entrance door, up to ten hours daily. Different amounts of daylight were measured in specific room scenarios to suggest on the most comfortable indoor living space. The recorded mean value for indoor varied from 37 to 286 lux, while in the corridor area 192 to 3,848 lux. However, the use of the large overhangs over the windows, wall openings in the room and trees with large canopy in the landscape setting should critically justify when the adequacy of daylight was drastically reduced in certain rooms.

BACKGROUND The SARS-CoV-2 outbreak may motivate smokers to attempt to stop in greater numbers. However, given the temporary closure of UK stop smoking services and vape shops, smokers attempting to quit may instead seek out digital support, such as websites and smartphone apps. OBJECTIVE We examined, using an interrupted time series approach, whether the SARS-CoV-2 outbreak has been associated with a step change or increasing trend in UK downloads of an otherwise popular smoking cessation app, Smoke Free. METHODS Data were from daily and non-daily adult smokers in the UK who had downloaded the Smoke Free app between 1 January 2020 and 31 March 2020 (primary analysis) and 1 January 2019 and 31 March 2020 (secondary analysis). The outcome variable was the number of downloads aggregated at the 12-hourly (primary analysis) or daily level (secondary analysis). The explanatory variable was the start of the SARS-CoV-2 outbreak, operationalised as 1 March 2020 (primary analysis) and 15 January 2020 (secondary analysis). Generalised Additive Mixed Models adjusted for relevant covariates were fitted. RESULTS Data were collected on 45,105 (primary analysis) and 119,881 (secondary analysis) users. In both analyses, there was no evidence for a step change or increasing trend in downloads attributable to the start of the SARS-CoV-2 outbreak. CONCLUSIONS In the UK, between 1 January 2020 and 31 March 2020, and between 1 January 2019 and 31 March 2020, there was no evidence that the SARS-CoV-2 outbreak has been associated with a surge in downloads of a popular smoking cessation app. CLINICALTRIAL osf.io/zan2s

AbstractIntroduction:Hospital evacuations of patients with special needs are extremely challenging, and it is difficult to train hospital workers for this rare event.Hypothesis/Problem:Researchers developed an in-situ simulation study investigating the effect of standardized checklists on the evacuation of a patient under general anesthesia from the operating room (OR) and hypothesized that checklists would improve the completion rate of critical actions and decrease evacuation time.Methods:A vertical evacuation of the high-fidelity manikin (SimMan3G; Laerdal Inc.; Norway) was performed and participants were asked to lead the team and evacuate the manikin to the ground floor after a mock fire alarm. Participants were randomized to two groups: one was given an evacuation checklist (checklist group [CG]) and the other was not (non-checklist group [NCG]). A total of 19 scenarios were run with 28 participants.Results:Mean scenario time, preparation phase of evacuation, and time to transport the manikin down the stairs did not differ significantly between groups (P = .369, .462, and .935, respectively). The CG group showed significantly better performance of critical actions, including securing the airway, taking additional drug supplies, and taking additional equipment supplies (P = .047, .001, and .001, respectively). In the post-evacuation surveys, 27 out of 28 participants agreed that checklists would improve the evacuation process in a real event.Conclusion:Standardized checklists increase the completion rate of pre-defined critical actions in evacuations out of the OR, which likely improves patient safety. Checklist use did not have a significant effect on total evacuation time.

Management of a ruptured hepatocellular adenoma during pregnancy is a rare and potentially life-threatening entity. Few case reports have described management of the pregnant patient who presents in haemorrhagic shock secondary to a ruptured liver adenoma. A 30-year-old primigravid woman at 31 weeks pregnant presented with abdominal pain and fetal bradycardia. After stat caesarean delivery of the infant, she had continued hemoperitoneum and was in shock secondary to an undiagnosed ruptured liver mass. General surgery was consulted intraoperatively and performed an exploratory laparotomy, packing and temporary closure. She was subsequently taken to interventional radiology (IR) for angioembolisation of the left hepatic artery. After stabilisation, she underwent formal abdominal closure. Management of a ruptured hepatocellular adenoma in pregnancy requires urgent multidisciplinary care including obstetrics gynaecology, general surgery and IR.

Fractional Stable Motion

For the evacuation dynamics in indoor space, a novel crowd flow model is put forward based on Linear Fractional Stable Motion. Based on position attraction and queuing time, the calculation formula of movement probability is defined and the queuing time is depicted according to linear fractal stable movement. At last, an experiment and simulation platform can be used for performance analysis, studying deeply the relation among system evacuation time, crowd density and exit flow rate. It is concluded that the evacuation time and the exit flow rate have positive correlations with the crowd density, and when the exit width reaches to the threshold value, it will not effectively decrease the evacuation time by further increasing the exit width.

The 3D mass evacuation simulation of an airplane accident is experimentally verified. Evacuee motion has been experimentally investigated by building a test field that emulates the interior of an actual regional airliner with a capacity of approximately 100 passengers. The experiment results indicate that the evacuation time tends to be affected by the number of passengers and the evacuee guidance at the emergency exit. The results also indicate that any evacuation delay in exiting by individual passengers only slightly affects the total evacuation time because of evacuee congestion in the aisles. Moreover, the importance of evacuation guidance notification was investigated based on the evacuation-order variance. Finally, the experimental results were compared to the corresponding simulation results. Simulations using appropriate evacuee walking speeds can provide valid evacuation times, which are the most important factor in designing evacuation drills. Consequently, these results should be applied to existing 3D simulations using precise KDH models for more accurate mass evacuation/rescue simulations.
