Purpose- Airline industry is very important for modern society and has a crucial role globalization business development by connecting regions, promoting global trade tourism hence enabling economic social development. Over the last two decades, troubled airlines were oftenly on news delebrating financial difficulties, layouts distrupted sceduled flights. Covid-19 also impact deterioration of d...

The recent banking crisis highlights the challenges faced in credit intermediation. New online peerto-peer lending markets offer opportunities to examine lending models that primarily cater to small borrowers and that generate more types of information on which to screen. This paper evaluates screening in a peer-to-peer market where lenders observe both standard financial information and soft, ...

We present an equilibrium model of a moral-hazard economy with a very large firm and financial markets, where a stock and bonds are traded. We show that optimal contracts necessitate the principal to forbid the agent to trade the stock, and that moral hazard problems can result in low interest rates and sometimes in high equity premium. We also obtain a number of striking results: the second be...

BACKGROUND & OBJECTIVES India has switched over to artemisinin-based combination therapy (ACT) for the treatment of acute uncomplicated Plasmodium falciparum malaria and the ACT used in the national programme is artesunate + sulphadoxine-pyrimethamine. Since the efficacy of ACT is dependent also on the partner drug, there is a need to evaluate and deploy multiple ACTs. METHODS This multicentr...

The current banking crisis highlights the challenges faced in the traditional lending model, particularly in terms of screening smaller borrowers. The recent growth in online peer-to-peer lending marketplaces offers opportunities to examine different lending models that rely on screening by multiple peers. This paper evaluates the screening ability of lenders in such peer-topeer markets. Our me...

The influence of rifampicin, streptolydigin, tetracycline and chloramphenicol on phage DNA transport from the T7 virion into the E. coli cell was studied. It has been found that the DNA transport proceeds in at least three stages. During the initial stage the phage injects into the host cell the left approximately 10 per cent of its DNA molecule. The entrance of the next 50 per cent of 17 DNA m...

We study the dynamics of a ferromagnetic domain wall driven by an external magnetic field through a disordered medium. The avalanchelike motion of the domain walls between pinned configurations produces a noise known as the Barkhausen effect. We discuss experimental results on soft ferromagnetic materials, with reference to the domain structure and the sample geometry, and report Barkhausen noi...

The sliding columnar phase is a liquid-crystalline phase of matter composed of two-dimensional smectic lattices stacked one on top of the other. This phase is characterized by strong orientational but weak positional correlations between lattices in neighboring layers and a vanishing shear modulus for sliding lattices relative to each other. A simplified elasticity theory of the phase only allo...
