We study how financial flexibility impacts on firm's investment decisions under uncertainty. use a comprehensive dataset covering US firms for the period 1983–2019. develop baseline model of uncertainty and characterize bindingness constraints. then this to explore firms’ responses in presence constraints different assumptions regarding value they assign flexibility. Our results point negative ...

We report the first inorganic/organic hybrids that show outstanding mechanical properties (withstanding cyclic loading) and bone bioactivity. This new hybrid material may fulfil unmet clinical need for bioactive synthetic grafts can withstand loading. A SiO 2 /PTHF/PCL-diCOOH sol-gel system, combined inorganic organic co-networks at molecular level, previously demonstrated unprecedented synergy...

This research aims to assess the effect of temperature gradient developed within concrete slab rigid pavement, and investigate its impact when incorporated with traffic load, heat transfer pattern. The pavement model considers an isotropic, uniform, linear-elastic schemes simulate material properties. A numerical analysis approach was employed using Abaqus software 3D Solid model. loads were ob...

In a thick-dielectric electroluminescent (TDEL) device, which is variation of thin-film devices, one the insulation layers replaced by thick-film dielectric layer. High brightness and reliability are features TDEL owing to higher withstanding voltage This paper presents new type with bottom emission structure. The layer was manufactured spin coating using an ink material, mixture BaTiO3 powder ...

This work is undertaken to develop a methodology to enhance the management of dredged marine an the North of France. The main objective of this study is to determine the main characteristics of these sediments. In this order, physical, mineralogical and chemical properties of both types of sediments are measured. Moreover, their potential impacts on the environment are assessed throughout leach...

The authors present an epizootiological analysis of myxomatosis in Poland. The biological, physical and chemical properties of virus strains used for the production and control of 'Myxovac M' vaccine are discussed. The long-term stability, safety and efficacy of the vaccine are demonstrated. Laboratory experiments were confirmed in large-scale field observations.

This review article will highlight and discuss the advances made over the last 10 years pertaining to physical and chemical property improvements through pharmaceutical cocrystals and, hopefully, draw closer the fields of crystal engineering and pharmaceutical sciences.

The structures of epoxyquinomicins A (1), B (2), C (3) and D (4) were determined by spectroscopic studies. Compound 1 was determined to be (5R,6S)-2-(3-chloro-2-hydroxybenzoylamino)-5-hydroxymethyl-5,6-epo xy- 2-cyclohexene-1,4-dione. Compound 2 was revealed to be the dechlorinated derivative of 1. Compounds 3 and 4 were determined to be the reduced derivative of 2 and 1, respectively.
