Testing the impact of the drag coefficient on an F16 aircraft model, depending on the angle of attack a was performed. First, a navigation model was introduced describing the preliminary and computational assumptions of the model. The final part of the present paper contains the relationships between the wind angle and the wind correction angle at the angle of attack a = 00, a = 110, a = 130 for a full-scale F-16 aircraft. The tables present results of all the calculations for individual angles of attack, taking into account variable wind angles relative to the longitudinal axis of the runway. The values show the corrections calculated for an 1/19 scale aircraft model and for a full-scale F16 aircraft. The "right" and "left" designations represent the direction from which the wind blows in relation to the aircraft.

Abstract. In the study, the neural basis of emotional reactivity was investigated. Reactivity was operationalized as the impact of emotional pictures on the self-reported ongoing affective state. It was used to divide the subjects into high- and low-responders groups. Independent sources of brain activity were identified, localized with the DIPFIT method, and clustered across subjects to analyse the visual evoked potentials to affective pictures. Four of the identified clusters revealed effects of reactivity. The earliest two started about 120 ms from the stimulus onset and were located in the occipital lobe and the right temporoparietal junction. Another two with a latency of 200 ms were found in the orbitofrontal and the right dorsolateral cortices. Additionally, differences in pre-stimulus alpha level over the visual cortex were observed between the groups. The attentional modulation of perceptual processes is proposed as an early source of emotional reactivity, which forms an automatic mechanism of affective control. The role of top-down processes in affective appraisal and, finally, the experience of ongoing emotional states is also discussed.

This study attempted to identify the impact of internal work environment on the retention of healthcare providers at Turaif General Hospital in the Kingdom of Saudi Arabia. In particular, the study aimed to identify the dimensions of work circumstances, compensation, and relationship with colleagues, professional growth, and the level of healthcare providers’ retention. In order to achieve the study goals, the researcher used the descriptive analytical approach. The researcher used the questionnaire as the study tool. The study population comprised all the healthcare providers at Turaif General Hospital. Questionnaires were distributed to the entire study sample that consisted of 220 individuals. The number of questionnaires valid for study was 183 questionnaires. The research findings were as follows: the participants’ estimate of the work circumstances dimension was high (3.64), the participants’ estimate of the compensation dimension was moderate (3.32), the participants’ estimate of the relationship with colleagues dimension was high (3.62), the participants’ estimate of the professional growth dimension was weak (2.39), and the participants’ estimate of healthcare providers’ retention level was intermediate (2.75). Accordingly, the researcher’s major recommendations are: the need to create the right atmosphere for personnel in hospitals, the interest of the hospital to provide the appropriate conditions for the staff in terms of the physical and moral aspects for building the work adjustment in the staff, and conducting training courses and educational lectures for personnel in hospitals on how to cope with the work pressures.

The right to adequate housing is a constitutional imperative which is contained in section 26 of the Constitution. The state is tasked with the progressive realisation of this right. The allocation of housing has been plagued with challenges which impact negatively on the allocation process. This note analyses Ekurhuleni Metropolitan Municipality v Various Occupiers, Eden Park Extension 51 which dealt with a situation where one of the main reasons provided by the Supreme Court of Appeal for refusing the eviction order was because the appellants subjected the unlawful occupiers to defective waiting lists and failed to engage with the community regarding the compilation of the lists and the criteria used to identify beneficiaries. This case brings to the fore the importance of a coherent (reasonable) waiting list in eviction proceedings. This note further analyses the impact of the waiting list system in eviction proceedings and makes recommendations regarding what would constitute a coherent (reasonable) waiting list for the purpose of section 26(2) of the Constitution.

The concept of tolerance is gaining its importance in the midst of an international society suffering from violence, wars and internal and international crises. It is practiced by extremist and extremist forces and movements acting in the name of religion to exclude the different Muslim and non-Muslim people according to the unethical practices and methodologies of Islamic law and reality. , Cultural, civilization .. that distinguish our world today. The society today is suffering from the ideas of the intellectual and aesthetic views of the different ideologically, ethnically, culturally and religiously in the world of the South. This is what the end-of-history thesis of Fukuyama and the clash of civilizations represented to Huntington. Therefore, it is necessary to confront these extremist and extremist ideas and behaviors. Peace, security and freedom in the international community of justice and equality, needs to be addressed intellectual, cultural, moral and political before they are legal, these treatments are based on dialogue and cooperation and trust and respect and mutual recognition and tolerance so we find the importance of tolerance to The international community is concerned about the need for mechanisms that confront terrorism and violence with an ideology based on respect for the right of diversity, diversity and pluralism. Accordingly, tolerance is a political, cultural and moral necessity based on international legal foundations represented by the United Nations. Through its conferences, declarations and international resolutions issued by it and its specialized agencies, culminating in the Universal Declaration of Tolerance and the International Day of International Peace, and the political foundations represented by democracy and global citizenship that respects all identities and seeks to respect the rights of other identities under the umbrella of international identity Nsanhuahdh respects everyone, a society with a humanitarian goal of a global civil and Ahdlaaaraf borders and the identity of certain Qomahdolh, cultural and educational foundations through plans and programs with educational encourage a spirit of tolerance and world peace. The study was divided into three topics: the first dealt with the concept of tolerance and world peace, and the second topic dealt with the impact of international law and citizenship. In the promotion of world peace "as one of the elements of global tolerance. The last topic included" the role of democracy and education education "in the promotion of world peace and concluded the study by conclusion.

The Right to Information Act 2005 was passed by the UPA (United Progressive Alliance) Government with a sense of pride. It flaunted the Act as a milestone in India’s democratic journey. It is five years since the RTI was passed; the performance on the implementation frontis far from perfect. Consequently, the impact on the attitude, mindset and behaviour patterns of the public authorities and the people is not as it was expected to be. Most of the people are still not aware of their newly acquired power. Among those who are aware, a major chunk either does not know how to wield it or lacks the guts and gumption to invoke the RTI. A little more stimulation by the Government, NGOs and other enlightened and empowered citizens can augment the benefits of this Act manifold. RTI will help not only in mitigating corruption in public life but also in alleviating poverty- the two monstrous maladies of India.

Art, Idleness and Food: The Ethics of War Communism and the Origins of Production Art, 1918–1919

Theory Of Production

The article examines the impact of the discourses concerning idleness and food on the formation of “production art” in the socio-political context of revolutionary Petrograd. The author argues that the development of the theory and practice of this early productionism was closely related to the larger political, social and ideological processes in the city. The Futurists, who were in the epicenter of Petrograd politics during the Civil War (1918–1921), were well acquainted with both of the discourses mentioned, and they contrasted the idleness of the old art with the dedicated labor of the “artist-proletarians” whom they valued as highly as people in the “traditional” working professions. And the search for the “right to exist” became the most important goal in a starving city dominated by the ideology of radical communism. The author departs from the prevailing approach in the literature, which links the artistic thought of the Futurists to Soviet ideology in its abstract, generalized form, and instead elucidates ideological influences in order to consider the early production texts in their immediate social and political contexts. The article shows that the basic concepts of production art (“artist-proletarian,” “creative labor,” etc.) were part of the mainstream trends in the politics of “red Petrograd.” The Futurists borrowed the popular notion of the “commune” for the title of their main newspaper but also worked with the Committees of the Rural Poor and with the state institutions for procurement and distribution. They took an active part in the Fine Art Department of Narkompros (People’s Commissariat of Education). The theory of production art was created under these conditions. The individualistic protest and “aesthetic terror” of pre-revolutionary Futurism had to be reconsidered, and new state policy measures were based on them. The harsh socio-economic context of war communism prompted artists to rethink their own role in the “impending commune.” Further development of these ideas led to the Constructivist movement and strongly influenced the extremely diverse trends within the “left art” of the 1920s.

Civil wars are one of the most pressing problems facing the world. Common approaches such as mediation, intervention, and peacekeeping have produced some results in managing ongoing civil wars, but they fall short in preventing civil wars in the first place. This book argues for considering civil wars from a developmental perspective to identify steps to assure that nascent, low-level armed conflicts do not escalate to full-scale civil wars. We show that highly structured intergovernmental organizations (IGOs, e.g. the World Bank or IMF) are particularly well positioned to engage in civil war prevention. Such organizations have both an enduring self-interest in member-state peace and stability and potent (economic) tools to incentivize peaceful conflict resolution. The book advances the hypothesis that countries that belong to a larger number of highly structured IGOs face a significantly lower risk that emerging low-level armed conflicts on their territories will escalate to full-scale civil wars. Systematic analyses of over 260 low-level armed conflicts that have occurred around the globe since World War II provide consistent and robust support for this hypothesis. The impact of a greater number of memberships in highly structured IGOs is substantial, cutting the risk of escalation by over one-half. Case evidence from Indonesia’s East Timor conflict, Ivory Coast’s post-2010 election crisis, and from the early stages of the conflict in Syria in 2011 provide additional evidence that memberships in highly structured IGOs are indeed key to understanding why some low-level armed conflicts escalate to civil wars and others do not.
