OBJECTIVES To explore the success of the introduction of the National Health Service (NHS) 111 urgent care service and describe service activity in the period 2014-2016. DESIGN Comparative mixed method case study of five NHS 111 service providers and analysis of national level routine data on activity and service use. SETTINGS AND DATA Our primary research involved five NHS 111 sites in Eng...

The results of a study the crystal structure and surface conductivity Si(111) silicon substrate with reconstructed after deposition submonolayer doses lithium are presented. We used method low energy electron diffraction to changes in lattice surface, as well four-point probe for measuring substrates under situ conditions. As initial surfaces, we Si(111)7x7 reconstruction an atomically clean su...

The chemical stability of Si(111), terminated with bilayer AlSe and GaSe, upon exposure to atmosphere, N2 and O2 was investigated with core-level and valence band photoelectron spectroscopy. Si(111):GaSe and Si(111):AlSe both form stable, unreconstructed surfaces with no states in the silicon energy gap; their atomic structures are nearly identical. However, similarities in surface electronic a...

In this study, the preparation of 111In-Bleomycin complex was optimized for temperature, time, concentration and pH during several experiments. The results showed that by the addition of bleomycin to 111In-InCl3 sample (dried under flow of N2) and heating the mixture up to 90-100°C the radiopharmaceutical can be obtained in 99.5% yield and a specific activity of 1.745 Ci/mmol. The final s...

The catalytic dry reforming (DR) process is a clean approach to transform CO2 into H2 and CO-rich synthetic gas that can be used for various energy applications such as Fischer–Tropsch fuels production. A novel framework proposed determine the optimum reaction configurations pathways DR of C1-C4 hydrocarbons via mechanism generator (RMG). With aid machine learning, variation thermodynamic micro...

The use of Pt–Rh catalysts is central in a number industrial processes, and to explain their performance it essential have solid understanding nanoscopic surface structure. Here we scanning tunneling microscopy investigate the growth, elemental nanostructuring, reconstruction behavior various near-surface alloys (NSA) on fcc Rh(111) Pt(111). We document formation novel lamellar island atop Pt/R...

We investigated the oxygen-reduction reaction (ORR) on Pd monolayers on various surfaces and on Pd alloys to obtain a substitute for Pt and to elucidate the origin of their activity. The activity of Pd monolayers supported on Ru(0001), Rh(111), Ir(111), Pt(111), and Au(111) increased in the following order: Pd/Ru(0001) < Pd/Ir(111) < Pd/Rh(111) < Pd/Au(111) < Pd/Pt(111). Their activity was corr...

Retroviruses are the causative agents of serious diseases, such as acquired immunodeficiency syndromes and several cancers, and are also useful gene therapy vectors. Retroviruses contain two sense-strand RNA genomes, which become linked at their 5¢ ends to form an RNA dimer. Understanding the molecular basis for dimerization may yield new approaches for controlling viral infectivity. Because th...

The idea of a "digital signature" first appeared in Diffie and Hellman’s seminal paper, "New Directions in Cryptography" [DH76]. They propose that each user U publishes a "public key", while keeping secret a "secret key". User U’s signature for a message m is a value σ depending on m and his public and secret keys such that U can generate σ and anyone can verify the validity of σ using U’s publ...
