Nerve agents that irreversibly deactivate the enzyme acetylcholinesterase are extremely toxic weapons of mass destruction. Thus, developing methods to detect these lethal is important. To create an optical sensor for a surrogate nerve agent tabun, as well physical barrier dissolves in response this analyte, we devise network hydrogel decomposes via self-propagating cascade. A Meldrums acid-deri...

A ‘Big Bad Bug’ threatens Lewis’s Humean metaphysics of chance (Lewis 1986a, p. XIV); his Principal Principle provides an intuitive link between and credence. Yet on the one hand, certain future developments are incompatible with true theory chance, but other such have a positive to occur. The combination these two claims leads inconsistent credences. I present solution Bug: chances relative li...

In this paper, we address a thorny challenge: how can entrepreneurship scholarship enhance its impact without compromising the pursuit of conceptual rigor and theoretical novelty? We propose prospective inquiry framework for entrepreneurship. It aims to align scholarly novelty with entrepreneurs' focus on future, in shared aspiration make difference world. By expanding work toward formulation, ...

The measurement problem concerns an apparent conflict between the two fundamental principles of quantum mechanics, namely Schrödinger equation and postulate. These describe inconsistent behavior for systems in so-called “measurement contexts.” Many theorists have thought that can only be resolved by proposing a mechanistic explanation (genuine or apparent) wavefunction collapse avoids explicit ...

Introduction: Sambiloto (Andrographis paniculata) is an antidiabetic medicinal plant that acts by inhibiting the ?-amylase enzyme. Andrographolide, active compound of sambiloto leaf, insoluble in water but dissolves ethanol. Aim: This study compared vitro activity aqueous extract and ethanolic leaf with Methods: The inhibitory test enzyme was carried out using ultraviolet-visible spectrophotome...

To study the influence of sinter basicity on microstructure, phase composition, and physicochemical metallurgical properties, samples agglomerates with different basicities were sintered investigated. A comprehensive structure, chemical, properties was conducted, optimum values for these determined. The results mineralogical transformations that occurred during sintering process are also presen...

Abstract How we understand the nature and role of grief depends on what take its object to be vice versa. This paper focuses recent claims by philosophers that is frequently or even inherently irrational inappropriate in one another respect, all which hinge assumptions concerning proper grief. By emphasizing temporally extended structure grief, offer an alternative account undermines these diss...

Heat-resisting alloys are designed to survive high-temperature oxidation by forming a slow-growing scale, usually Cr 2 O 3 , which acts as barrier between the metal and its environment. However, that succeed in this way when exposed hot oxygen or air fail do so CO gas. Instead, they exhibit rapid “breakaway” corrosion, developing oxides of alloy base iron and/or nickel. The growth these non-pro...
