The NPFIT strategy for information security of care record service

The National Programme for IT in England doesn’t have a one-document strategy for its information security of the Care Records Service, which is the national EHR system. This paper provides a comprehensive understanding of the information security strategy of England’s EHR system by presenting its different information security issues such as consent mechanisms, access control, sharing level, and related legal and regulations documents

Coupled-cluster calculations for the ground- and excited-states of the spin-half XXZ model

The coupled-cluster method is applied to the spin-1/2 antiferromagnetic XXZ model on a square lattice by employing an approximation which contains two-body long-range correlations and high-order four-body local correlations. Improvement is found for the ground-state energy, sublattice magnetization, and the critical anisotropy when comparing with the approximation including the two-body correlations alone. We also obtain the full excitation spectrum which is in good agreement with the quantum Monte Carlo results and the high-order spin-wave theory.Comment: 20 pages, 6 figure

Chemical and biological investigations of Delonix regia (Bojer ex Hook.) Raf.

U radu je opisana izolacija pet sastojaka petroleterske i diklormetanske frakcije metanolnog ekstrakta kore biljke Delonix regia: lupeol (1), epilupeol (2), β-sitosterol (3), stigmasterol (4) i p-metoksibenzaldehid (5). Nadalje, testirano je antimikrobno djelovanje različitih ekstrakata difuzijskom metodom na disku (15 μg mm2). Zone inhibicije za sastojke topljive u petroleteru, tetraklormetanu i diklormetanu bile su 914 mm, 1113 mm, odnosno 920 mm, dok je zona inhibicije standarda kanamicina bila 2025 mm. U biološkom pokusu smrtnosti morskih kozica najveću toksičnost pokazali su spojevi topljivi u tetraklormetanu (LC50 = 0,83 μg mL1), dok je topljivost sastojaka topljivih u petroleteru i diklormetanu bila LC50 14,94, odnosno 3,29 μg mL1, a standarda vinkristin sulfata 0,812 μg mL1. Ovo je prvo izvješće o izolaciji sastojaka, antimikrobnom djelovanju i citotoksičnosti biljke D. regia.In this study five compounds, lupeol (1), epilupeol (2), β-sitosterol (3), stigmasterol (4) and p-methoxybenzaldehyde (5) were isolated from the petroleum ether and dichloromethane fractions of a methanolic extract of the stem bark of Delonix regia. Antimicrobial screening of the different extracts (15 μg mm2) was conducted by disc diffusion method. The zones of inhibition demonstrated by the petroleum ether, carbon tetrachloride and dichloromethane fractions ranged from 914 mm, 1113 mm and 920 mm, respectively, compared to kanamycin standard with the zone of inhibition of 2025 mm. In brine shrimp lethality bioassay, the carbon tetrachloride soluble materials demonstrated the highest toxicity with LC50 of 0.83 μg mL1, while petroleum ether and dichloromethane soluble partitionates of the methanolic extract revealed LC50 of 14.94 and 3.29 μg mL1, respectively, in comparison with standard vincristine sulphate with LC50 of 0.812 μg mL1. This is the first report on compounds separation from D. regia, their antimicrobial activity and cytotoxicity

Photonic Anomalous Quantum Hall Effect

We experimentally realize a photonic analogue of the anomalous quantum Hall insulator using a two-dimensional (2D) array of coupled ring resonators. Similar to the Haldane model, our 2D array is translation invariant, has zero net gauge flux threading the lattice, and exploits next-nearest neighbor couplings to achieve a topologically non-trivial bandgap. Using direct imaging and on-chip transmission measurements, we show that the bandgap hosts topologically robust edge states. We demonstrate a topological phase transition to a conventional insulator by frequency detuning the ring resonators and thereby breaking the inversion symmetry of the lattice. Furthermore, the clockwise or the counter-clockwise circulation of photons in the ring resonators constitutes a pseudospin degree of freedom. We show that the two pseudospins acquire opposite hopping phases and their respective edge states propagate in opposite directions. These results are promising for the development of robust reconfigurable integrated nanophotonic devices for applications in classical and quantum information processing

Dairy Market Participation with Endogenous Livestock Ownership: Evidence from Cote d'Ivoire

This study evaluates determinants of dairy market participation by agricultural households in Cote dIvoire by using the Heckman selection model to correct for endogenous cattle ownership. A key result is that ignoring the population of non-owners biases estimates of market participation parameters. These findings are important in light of the widespread application of livestock market participation analyses that assume cattle ownership is exogeneous.Cote dIvoire, dairy, endogenous adoption, Heckman selection model, market participation, Livestock Production/Industries,

Legislasi Hukum Kewarisan Di Indonesia

Inheritance law is one part of the civil law as a wholeand is the smallest part of family law. Inheritancelaw in Indonesia is still very pluralistic covers threeareas of law, namely the customary inheritance law,Islamic law and the civil law of inheritance (BW).The third system of inheritance law applies despitetogether but in reality do not always go hand inhand, and often lead to conflict. For people who areMuslims, Islamic inheritance law is based on IslamicLaw Compilation (KHI) is not a legal provision thatis imperative. Thus Islamic law for Muslims inIndonesia are voluntary (choice of law). How toshape legislation inheritance law in Indonesia, be atopic of studies in this paper
