Erythemal UV Dose and UV Index Measurement at 37th North Latitude and Its Possible Effects on Humans

In this study, UV irradiance and UV erythemal and UV index data of May, June, July and August measured in Adana (longitute=36 E, latitute=37 N altitute=140m) between 2013 and 2019 were analyzed. As a result of the analysis, the average of four months was 14.16 MED (2.9736 J/m2) and the highest value of these four months was calculated as 15.6 MED (3.276 J/m2) in July. The percentage frequency of the total daily UV dose was also calculated and it was determined that the region was under the effect of 70-80% high UV dose. In addition, it was calculated to have a high UV index according to local time (10.00-14.00). It was concluded that this situation poses a great risk for workers working in agricultural areas in the region and for people who spend their summer holidays by the sea. UV Dose-Ozone, UV Dose-temperature, UV Dose-humidity and Ozone-temperature correlations were also calculated. As a result of the comparison, it was found that there was an R= -0.64 correlation between UV-ozone, an R= -1.00 correlation between temperature and ozone, and a direct correlation of R= 0.60 between UV radiation and temperature.

Twice-Exceptional Students

Young people who present with concomitant high ability and disabilities represent one of education's greatest conundrums. While on one hand they appear capable of superior academic performance, on the other hand they struggle as students. Consequently, identification and educational services for the twice-exceptional student population remain bewildering and elusive as the combination of seemingly paradoxical traits puts them at great risk for identification and consequently this population of students is rarely served appropriately. This chapter explores the complexities of the twice-exceptional (2e) population, how they should be viewed, how schools and homes can accommodate what seem to be dichotomous needs, and how ultimately they can be successful and contented. Case examples amplify understanding of this challenging group of young people.

Effect of Exit Door Width on Flow Rate in Occupant-based Fire Evacuation Scenarios in Dormitories

Student dormitories are intensely used buildings that meet the resting, accommodation and living needs of students. It is necessary to ensure the safety of students and to eliminate possible risks in dormitories as intensive use areas. Fires pose a great risk in dormitories and may cause serious casualties and injuries. The reduction of casualties and injuries can be achieved by analyzing occupant behaviour during fires according to the building use scenarios. In this paper, a type of dormitory that provides two alternative exits is explored. The building use scenarios of the dormitory were investigated by making on-site observations. Students’ use of sleeping units, dining units and partial sleeping/dining units and fire exit routes were determined. Pathfinder computer program was used to analyze the fire evacuation performance. This program was defined in accordance with occupant behaviour and different fire evacuation times were suggested depending on the building use scenarios. At the end of the study, based on the evacuation times, the flow rate at the exit doors according to the location of the occupants was analyzed. In the fire escape routes, as the upper floors are reached from the lower floors, the occupant flow rate decreases at the exit doors and the flow rates continue to be stable as the number of occupants is saturated according to the door width. The decrease in the number of occupants in the dining unit decreases the flow rate at the exit doors. It is important that various assembly units in dormitories, such as the dining unit, are designed on floors that can directly provide evacuation to a safe area. The results obtained are suitable for all dormitories, residences, hotels and other similar buildings. Keywords: building use scenario, dormitory, evacuation, flow rate, exit widths

Central European History in the Age of COVID-19

As COVID-19 began to spread across the globe in early 2020, few could have envisaged that it would so profoundly affect our personal and professional lives. In-class teaching soon had to be either replaced with online teaching or could only be carried out with great risk to staff and students. Working from home and a constant stream of video conferences became the norm instead of informal chats on departmental corridors. As if all of this were not bad enough, positions for junior academics, already scarce in the wake of the general financial crisis and the rise of the neoliberal university, were cut. Travel funding was slashed by many universities, and most countries closed their borders. Libraries were closed or could only be accessed with considerable difficulty. Archives were shut or, if they reopened, operated long waiting lists. In situ research, essential for historians of central Europe, became difficult, if not impossible.

Das Ngrowo-Ngasinan: Pengaruh dan Manfaatnya Terhadap Tinggalan Arkeologi Di Trenggalek

The Ngrowo-Ngasinan watershed is one of the Brantas watersheds covering an area of ​​1,188,800 hectares located in the Trenggalek Regency. The Ngrowo-Ngasinan watershed consists of forests, fields, irrigated rice fields, plantations, and settlements which are flooded every year. Flood conditions that occur have an influence on archaeological remains around the Ngrowo-Ngasinan watershed, namely Brongkah Temple, Semarum Site and Kamulan. Most of the archaeological remains are buried by alluvial deposits due to flooding and the overflow of the Ngrowo – Ngasinan River. The results of research conducted by Balar DIY in 2012-2015 through survey and excavation data collection methods indicate that the Semarun and Kamulan sites were abandoned because they were inundated and drowned due to the overflow (flood) of the Ngrowo and Ngasinan rivers. The purpose of this article is to determine the effect of the existence of the Ngrowo-Ngasinan watershed on the loss or damage of archaeological sites around the Ngrowo-Ngasinan watershed. Morphologically, the archaeological sites in the Ngrowo-Ngasinan watershed have a very ideal position as a place of settlement, because their location is in a basin and sloping area, fertile, and close to water sources. The conclusion should be at the end of the abstract. Avoid the word 'disaster' (adjust title). Conclusion: The selection of residential locations around the Ngrowo-Ngasinan watershed has a very significant impact or great risk for flood disasters because of its location on the banks of the river. Keywords: Ngrowo-Ngasinan Watershed, archaeological remains, flood.

Can touch this: training to correct police officer beliefs about overdose from incidental contact with fentanyl

Misinformation about overdose risk from accidentally inhaling or touching fentanyl is widespread among police in the United States. This may aggravate already elevated burdens of officer stress and burnout, while chilling lifesaving overdose response. Police education has shown promise in reducing false beliefs about fentanyl. To better understand the potential of training interventions in correcting officer knowledge, we administered a 10-min online training with corrective messaging about occupational overdose risk from fentanyl contact to 204 police officers in Indiana. Overall, 129 officers (63%) completed baseline survey and 69 (34%) completed follow-up instrument. Using a 6-point Likert scale, we documented assent with the statement: “First responders who encounter fentanyl are at great risk of overdose by touching it or inhaling it.” At baseline, 79.8% expressed agreement, while 20.2% disagreed. At follow-up, 39.1% agreed, while 60.9% disagreed (p < .001). Baseline responses varied in that those officers without a college degree and those on patrol were more likely to report false beliefs. A brief online training intervention holds promise for correcting false beliefs about the risk of fentanyl overdose under circumstances commonly encountered by police.

Two-Step Approach Using Degradable Magnesium to Inhibit Surface Biofilm and Subsequently Kill Planktonic Bacteria

Bacterial infection remains a great risk in medical implantation surgery. In this paper, we found that degradable metals may be a feasible alternative option of antibacterial implantation materials. It is known that the spalling mechanism of magnesium (Mg) during degradation leads to Mg ions-induced alkaline environment, which is harmful to planktonic bacteria. In this study, we showed that alkaline pH environment is almost harmless to those adhesive bacteria protected in well-formed biofilms. Moreover, experimental results demonstrated that the biofilm formed in the place where Mg spalls are destroyed, releasing the covered bacteria to be planktonic in the alkaline environment. As a result, the colonization of biofilms continues to shrink during the degradation of Mg. It implies that if degradable metal is employed as implantation material, even if bacterial infection occurs, it may be possibly cured without second surgery.

Trichomonas gallinae infections in the naïve host Montifringilla nivalis subsp. nivalis

Infectious diseases bear a great risk for populations of naïve host species. In the present article we inform about the first microscopic and molecular detection of the bird pathogen Trichomonas gallinae in the White-winged Snowfinch (Montifringilla nivalis subsp. nivalis). The emergence of trichomonosis in this highly specialised alpine bird species may pose a serious threat to its already declining population. Interspecies transmission of T. gallinae most likely occurred at a bird feeder in a Swiss mountain village. Monitoring of the disease and immediate measures to prevent its spread are urgently needed.

A Theory of Partial Property Rights and the Illusion of State-Owned Enterprises

China’s State-Owned Enterprises (SOEs) enjoy many special benefits. They do not turn over profits and rents to the state, they pay much less interests than other enterprises in their use of capital, they enjoy monopolistic power in the marketplace, incomes of SOE employees, including managers, are free of policy restrictions. Because these substantial interests are not transferrable to individuals, competition exists for them. Compared with executives of private enterprise, senior managers of SOEs are 94 times more likely of being convicted of a crime. High benefits enjoyed by senior managers of SOEs come with a great risk. Once the illusion of SOEs is punctured, SOE leaders with higher education and long-term visions may become the driving force of SOE reform.
