The vibrational density of states DOS of hydrogen trapped at dislocations in deformed PdH0.0008 has been measured at 4 and 295 K with incoherent inelastic neutron scattering. The vibrational DOS at 4 K exhibits features characteristic of the low-temperature -Pd hydride phase while the characteristic peak in the 295 K DOS corresponds to the solid-solution -Pd phase. This is evidence of a → trans...

well-defined crystalline pbse nanocubes and nanospheres have been synthesized through a simple hydrothermal method by using pb2+- edta and pb2+- oleylamine complexes at 180°c for different reaction times. composition and morphology of the samples have been characterized by means of xrd and sem. gradual release process of pb2+ from pb2+-edta and pb2+-oleylamine complexes can adjust the growth ra...

The efficient, simultaneous synthesis of structurally diverse compounds, better known as diversity-oriented synthesis (DOS), is not obvious, and remains a challenge to synthetic chemistry. This personal account details why DOS has such enormous implications for the discovery of small molecules with desired properties, such as catalysts, synthetic reagents, biological probes and new drugs, Also,...

The definition and main results connected with Gröbner basis, Hilbert series and Anick's resolution are formulated. The method of the infinity behavior prediction of Gröbner basis in noncommu-tative case is presented. The extensions of BERGMAN package for IBM PC compatible computers are described. Let A =< X|R > be a finitely presented associative algebra over field K. Here are the main example...

ndudablemente, MS-DOSR (MicroSoft Disk Operating System) ha sido el sistema operativo de mayor éxito en la historia, estando presente en una amplia base de equipos de tipo personal. Si bien se le considera obsoleto después de la aparición de nuevos sistemas tales como Windows, DOS aún representa una herramienta flexible y sumamente poderosa como monitor para equipos dedicados, principalmente pa...

Secure authentication features of communication and electronic commerce protocols involve computationally expensive and memory intensive cryptographic operations that have the potential to be turned into denial-of-service (DoS) exploits. Recent proposals attempt to improve DoS resistance by implementing a trade-off between the resources required for the potential victim(s) with the resources us...

Well-defined crystalline PbSe nanocubes and nanospheres have been synthesized through a simple hydrothermal method by using Pb2+- EDTA and Pb2+- oleylamine complexes at 180°C for different reaction times. Composition and morphology of the samples have been characterized by means of XRD and SEM. Gradual release process of Pb2+ from Pb2+-EDTA and Pb2+-oleylamine complexes can adjust the growth ra...

Digital's PATHWORKS for DOS version 4.1 personal computer integration software includes two network virtual device drivers for the Microsoft Windows environment. These drivers allow Windows applications operating in a protected processor mode and standard DOS applications in a virtual machine to concurrently access services designed to run in real mode under the DOS operating system. The networ...
