Abstract:
Through this paper an attempt is made to focus on a special technology based on application of thrust reverser in turbofan engine which is common to the aviation industries but an uncommon in general. The airlines accept that thrust reverser is necessary for safe operations because it provides an added margin of safety for transport aircraft operations. In this technology, forward thrust produced by turbofan engine of aircraft is diverged to reverse direction so as to provide an additional deceleration effect during landing and power back effect. This technique is employed for improving aircra

Abstract:
Abstract Active thrust faults pose a significant seismic hazard worldwide. Many of these faults include “blind” thrusts, where the propagating fault tip does not reach the Earth's surface, and “buried” faults, where the geomorphic expression of the fault is obscured by subsequent sedimentation and/or erosion. This raises the issue of whether conventional geologic, geomorphic, and paleoseismic methods can be used to identify and characterize thrust faults for the assessment of seismic hazards or whether these faults sometimes are truly “blind.” We compiled a data base of 148 worldwide moderate-

Variable pitch low pressure ratio fans could enable higher propulsive efficiency and eliminate the need for heavy thrust reversers. In this paper, the effects of the fan rotor design on reverse thrust capability have been explored by varying key parameters of NASA’s Advanced Ducted Propulsor (ADP) while maintaining cruise point performance. Reverse thrust performance has been assessed using RANS single passage CFD of the variable pitch fan system with an extended domain. This computational approach has been validated using NASA Stage 51B, an experimental variable pitch fan test case. Predicted

Engine manufacturers recognize that a variable pitch fan blade can provide the necessary fan stall margin to take the next step in engine cycle improvement with enhanced propulsive efficiency and low noise level.

If they can also be re-pitched such that they generate sufficient reverse thrust, they could eliminate the engine drag and weight penalty associated with bypass duct thrust reversers.

Abstract:
The Mount Raymond map area incorporates the western limb of the Richardson anticlinorium, southern Richardson Mountains, northern Yukon. It is underlain by four Paleozoic sedimentary successions: middle Cambrian Slats Creek Formation, Cambrian to Early Devonian Road River Group, Devonian Canol Formation, and Late Devonian to Carboniferous Imperial and Tuttle formations. The Richardson trough depositional setting of the first three successions is succeeded by a deep-marine, turbiditic, Ellesmerian, orogenic foredeep setting for the Imperial-Tuttle succession.

Abstract:
Taxation is central to state building in post-conflict states. This reflects both the urgent need for revenue during post-conflict reconstruction and the broader governance implications of taxation related to state capacity building and the expansion of governmental responsiveness and accountability. In European states, taxation was historically central to enabling war and a longstanding literature suggests that conflict, or its threat, may increase tax collection. However, this centrality is not reflected in existing practice or research. It is unclear whether theoretical findings about the r

Abstract:
This policy brief analyses the phenomenon of conspiracy theories, and how they fit in the realm of research on violent extremism. Using the case study of QAnon, this Policy Brief looks at how the movement mobilises people to violence on social media and attempts to determine how different this this process is from any other process of radicalisation to violence. By combining discourse analysis of the movement’s Gab posts, interviewing former supporters, and analysing three illustrative case studies, this Policy Brief identifies five discourses - such as revenge, “the Other”, chosenness/ specia

Abstract:
This paper analyses the dynamics of policymaking among the various political institutions in Uruguay. The authors find that first, there are relatively stable policies, such as those allowing for the commercial and financial openness of the country. Then there are inflexible and low-quality policies, such as those related to social policies, some areas of state reform (civil servants' wages and hiring mechanisms), the bankruptcy regime, etc. Finally, there are volatile outcomes resulting from economic shocks, such as those related to discretionary public spending. In certain cases, the main ou

Abstract:
In many countries, tax administrations have only a low capacity to enforce tax collection. In such circumstances, public disclosure policies – where the compliance and/or non-compliance of taxpayers is made public – are an appealing tool to raise compliance. However, the effect of such policies in low-compliance settings is not well understood. Through a field experiment conducted in 2021 with over 65,000 property taxpayers in Kampala, Uganda, we study the effects of reporting delinquents and recognising compliers. While the threat of publicly disclosing delinquency raises compliance, subseque

Abstract:
Since the late 1970s, many countries have based their tax systems on self-assessment – taxpayers are expected to evaluate their liabilities autonomously, and voluntarily remit their tax due. If the tax system is perceived as fair and easy to navigate, with credible threat of penalisation for non-compliance, self-assessment reduces the cost of tax administration without significant revenue losses (Barr et al. 1977; Teviotdale and Thompson 1999; James and Alley 2004). On the other hand, self-assessment entails an increase in compliance costs for taxpayers, at the very least in terms of time spen

Abstract:
Pelargonium (Geranium) is the number one pot plant in many areas of the United States and Europe. Israel and the U.S. send to Europe rooted cuttings, foundation stocks and finished plants to supply a certain share of the market. Geraniums are propagated mainly vegetatively from cuttings. Consequently, viral diseases have been and remain a major threat to the production and quality of the crop. Among the viruses isolated from naturally infected geraniums, 11 are not specific to Pelargonium and occur in other crops while 6 other viruses seem to be limited to geranium. However, several of these v
