The regulated airspace in which aircraft flights take place is part of the Earth's atmosphere. At the same time, the same airspace is the seat of meteorological process and phenomena that have no borders and whose activity is not regulated, but whose evolution in time and behavior is governed by their own laws. This study presents, in a descriptive manner, low level dangerous weather conditions associated with wind shear also called the invisible killer. The phenomenon can occur locally, extremely rarely (3-4 times per year) during winter operations, mainly in January, under the activity of Mediterranean cyclones and its uniqueness consists in duration and intensity. To highlight the impact on flight safety in winter operations, especially in the current context of global warming, the reference and analysis periods applicable to this study are indissolubly reduced to days and minutes. When we talk about flight safety, the immediate application of corrective actions by pilots, the reference period is indissolubly reduced to seconds, those seconds that can make the difference between life and death

The Impact

The characteristics of low-level wind shear (LLWS) over the Chinese mainland were investigated using reports from pilots, air traffic controllers and the number of arriving/departing flights from 2016 to 2020. A preliminary analysis of the impact of the flights on the LLWS reports was carried out, and the cause of LLWS was also investigated. LLWS reports from most airports indicate that LLWS is most likely to occur within 600 m AGL with a higher density below 300 m, but with some exceptions, as wind shear is reported at higher altitudes at some airports. Airports with a high frequency of LLWS reports are almost all located in or around regions with complex topography and in regions with prevailing weather conditions favorable to LLWS. The variation in overall LLWS reports displays a steady increase from 2016 to 2019 and a decrease from 2019 to 2020, consistent with the trend in the number of flights, but with no evidently similar trends for individual airports. Seasonal variations in LLWS reports are observed and demonstrate no notable impact caused by the number of flights, implying that the main cause is the monthly variation of weather conditions. Diurnal variation is also evident and largely associated with the variation in number of flights during the busy period in addition to weather conditions, such as common strong winds, in the afternoon.

The dissemination of fake news is a problem that has already been addressed but by no means is solved. After the manipulation made by Cambridge Analytica which was based on classifying users by their political views and targeting specific political propaganda on the Brexit campaign, the Trump election and the Bolsonaro election, there is no doubt this issue can have a real impact on society in ‘normal times’. During a pandemic, any type of fake news can be the difference between life and death when the data shared can directly hurt the people who are believing in it. Moreover, there is also a new trend of using artificial robots to disseminate such news with a special target on Twitter which can be linked with political campaigns. Thus, it is essential that we identify and understand what kind of news is selected to be 'dressed' as fake and how it is disseminated. This paper aims to investigate the dissemination of fake news related with Covid-19 in the UK and Brazil in order to understand the impact of fake news on public sector actions, social isolation and quarantine imposition. Those two case studies are well versed on the fake news dissemination. Our initial dataset of Twitter posts have focused on posts from four different cities (Natal, São Paulo, Sheffield and London) and have shown interesting pointers that will be discussed.

In 2018, studies were conducted to assess the impact of foliar feeding with complex fertilizers on the yield and grain quality of two soybean varieties. Weather conditions throughout the year were noted periodically dry in May, June and August. Metallocene® fertilizers with different mineral nutrition elements were used for soybean spraying. The fertilizers were used for spraying in the soybean beginning bloom stage. Epy control served as a variant without foliar feeding. It was found that the variety Annushka in the conditions of 2018 was more productive than the variety Milyaushaa. The difference between the varieties in the control was 0.3 t/ha. Low yield in the control sample was associated with the negative effect of drought on the existing root system and the nudeles on it. Spraying Annushka crops by Metallocene® A with copper has high positive effect on the yield. The yield increase from this fertilizer was 0.72 t/ha. In case with Milyaushaa, the best indicators were achieved by Metallocene® D spraying with manganese. In case the yield increased by 0.79 t/ha. The use of foliar feeding had positive effect on soybean seed size. The maximum 1000 seed weight Annushka was for Metallocene® A with copper. For Milyaushaa the largest seeds were when using Metallocene® D with manganese. Foliar feeding by Metallocene® D with manganese had positive effect on phosphorus accumulation in seeds.

This study analyzed the difference between rural and urban older adults in Thailand regarding the relationship between the knowledge and behavior toward the prevention of contracting COVID-19. Path analysis was used to observe if the performance of protective behaviors was affected by the level of knowledge that older people have about the disease. This study used the Impact of COVID-19 on Older Persons in Thailand survey collected across the five regions of the country. Rural residents benefited from community network of village health volunteers who provided information during the pandemic but, they had disadvantages on accessing newer media sources, mainly the internet, for the latest developments on COVID-19. Rural older adults had a higher level of knowledge about COVID-19 than those in urban areas; no difference was observed regarding their behavior to prevent themselves from being infected. The knowledge-behavior gap was viewed as a mechanism of cognitive avoidance because of overwhelming unprecedented information.

The paper considers issues of interaction between aviation and avifauna, relevant in terms of flight safety and safety of habitats for birds living in the impact area of ​​ airports. A number of parameters of aircraft and air traffic flow significantly affect the behavior and diversity of birds living in the respective areas. The analysis showed that species composition of avifauna at airports includes very few fully synanthropic species, while semi-synanthropes, such as members of the family Corvidae, are often found in airport areas and, due to their size and behavior, are of major hazard to aircrafts. A variety of methods for assessing the level of ornithological hazard are proposed by researchers and used in some countries. The authors presented a matrix method for assessing the risk of collisions between birds and aircraft, adapted to the conditions of Ukrainian airports. In particular, this method takes into account the peculiarities of avifauna monitoring carried out at the airports of Ukraine and the range of data on birds that may be available at these enterprises. The proposed analytical approach to ornithological risk assessment and ornithological management was tested on the example of Boryspil Airport, for which the attractiveness of the territory for birds, focal species of birds that need the most attention during ornithological observations by the airport staff, and the risk level were determined. It is necessary to expand the list of indicators according to which data should be collected during routine ornithological monitoring of airports.

Perception is a vital part of driving. Every year, the loss in visibility due to snow, fog, and rain causes serious accidents worldwide. Therefore, it is important to be aware of the impact of weather conditions on perception performance while driving on highways and urban traffic in all weather conditions. The goal of this paper is to provide a survey of sensing technologies used to detect the surrounding environment and obstacles during driving maneuvers in different weather conditions. Firstly, some important historical milestones are presented. Secondly, the state-of-the-art automated driving applications (adaptive cruise control, pedestrian collision avoidance, etc.) are introduced with a focus on all-weather activity. Thirdly, the most involved sensor technologies (radar, lidar, ultrasonic, camera, and far-infrared) employed by automated driving applications are studied. Furthermore, the difference between the current and expected states of performance is determined by the use of spider charts. As a result, a fusion perspective is proposed that can fill gaps and increase the robustness of the perception system.

The aim of the research is to find out the impact of the Egyptian soap operas presented in Ramadan on the behavior of female university students and the sequence of values ​​they possess. What are the Egyptian drama types that are given to them on the grounds that television conveys the exaggerated reality، as some thinkers put it? Leads to the loss of social life from the prevailing traditions and the fall of old customs and excesses of tradition or the establishment of prevailing values ​​and focus on them The research is a study of the surveys that are interested in studying current or still occurring phenomena where the researcher examines the phenomenon in the place or environment in which it is present، and then collects and scans all the information about that problem or phenomenon، To achieve the goal of the research، the researcher distributed 120 form 60 form for female students of the Faculty of Education Girls and 60 form for students of the Faculty of Science Girls for the questionnaire form either the questionnaire was distributed as a second step on 102 students of them and the difference in the number was the result of absence of a number of students and neglect the form of another number for lack of scientific validity Use of frequencies and percentages and calculation of the value of the arithmetic mean and the test of the following: 1- Egyptian soap operas contribute to shaping public attitudes about values ​​and problems in society 2- Behavioral patterns of students are linked to what is promoted during the Egyptian series  And the importance of research from being discussing the problem began to Iraqi families suffer from it is a change in the behavior of young people، especially girls because of their exposure to drama and serials in general and the Egyptian series in particular The main results of the research were as follows: 1- lying is the most influential behavior by 16.6%، which makes these serials a real danger to the behavior of the Iraqi student، especially the behavior of expatriate and strange from the Iraqi society • The perception of the values ​​of the society negatively affected their exposure to the Egyptian series by 51% and their views changed to equality and justice in the Arab countries by 27.5% 3- It turns out that (65%) of the respondents see that the content of the Egyptian serials does not agree with the nature of the Iraqi society due to the prevailing customs، traditions، customs and behavior، especially dress، dress، forbidden drinking and forbidden relations، despite their admiration for these series 4- The most important reasons viewers watch the Egyptian series are getting used to watching them during the month of Ramadan، especially since most of the satellite channels show these serials to the Egyptian production in comparison with the rest of the Arab countries on the one hand and the weakness of the Iraqi drama and the other. On the other hand، the researcher sees the importance of the attention of television production institutions in Iraqi drama in terms of the selection of subjects، writing the script and the distinctive directing vision so that it can compete with the Arab drama especially the Egyptian drama.

Warming of the climate system is unequivocal, and many of the observed changes are unprecedented over five decades to millennia. Globally the atmosphere and ocean is increasingly getting warmer, the amount of ice on the earth is decreasing over the oceans, and the sea level has risen. According to Intergovernmental Panel on Climate Change, the total increasing temperature globally averaged combined land and surface between the average of the 1850-1900 period and the 2003 to 2012 period is 0.78 &deg;C (0.72 to 0.85). But should we prepare for such the relatively small change? The importance is not the mean of the warming but the considerable likelihood of climate change that could trigger extreme natural hazards. The impact and the risk of climate change associated with railway infrastructure have not been fully addressed in the literature due to the difference in local environmental parameters. On the other hand, the current railway network in Malaysia, over the last decade, has been significantly affected by severe weather conditions such as rainfall, lightning, wind and very high temperatures. Our research findings point out the extremes that can lead to asset system failure, degraded operation and ultimately, delays to train services. During the period of flood, the embankment of the track can be swept away and bridge can be demolished, while during drought, the embankment of the track can suffer from soil desiccation and embankment deterioration, high temperature increases the risk of track buckling and high winds can result in vegetation or foreign object incursion on to the infrastructure as well as additional quasi-static burden exerted. This review is of significant importance for planning and design of the newly proposed high speed rail link between Malaysia and Singapore.

Concerns about video-based political persuasion are prevalent in both popular and academic circles, predicated on the assumption that video is more compelling than text. To date, however, this assumption remains largely untested in the political domain. Here, we provide such a test. We begin by drawing a theoretical distinction between two dimensions for which video might be more efficacious than text: 1) one’s belief that a depicted event actually occurred and 2) the extent to which one’s attitudes and behavior are changed. We test this model across two high-powered survey experiments varying exposure to politically persuasive messaging (total n = 7,609 Americans; 26,584 observations). Respondents were shown a selection of persuasive messages drawn from a diverse sample of 72 clips. For each message, they were randomly assigned to one of three conditions: a short video, a detailed transcript of the video, or a control condition. Overall, we find that individuals are more likely to believe an event occurred when it is presented in video versus textual form, but the impact on attitudes and behavioral intentions is much smaller. Importantly, for both dimensions, these effects are highly stable across messages and respondent subgroups. Moreover, when it comes to attitudes and engagement, the difference between the video and text conditions is comparable to, if not smaller than, the difference between the text and control conditions. Taken together, these results call into question widely held assumptions about the unique persuasive power of political video over text.
