Bis[4-amino-N-(pyrimidin-2-yl)benzene­sulfonamidato]-κ2 N,N′;κN-aqua­bis­(dimethyl­formamide-κO)cadmium(II) monohydrate

In the title compound, [Cd(C10H9N4O2S)2(C3H7NO)2(H2O)]·H2O, the CdII ion displays a grossly distorted octa­hedral (or irregular) mer-CdN3O3 coodination polyhdron arising from its coordination by one N,N′-bidentate sulfadiazinate anion, one monodentate sulfadiazinate anion, two O-bonded dimethyl­formamide molecules and one water mol­ecule. A short Cd⋯N contact [2.890 (3) Å] to the monodentate sulfadiazinate ion also occurs. The dihedral angles between the planes of the aromatic rings of the anions are 86.81 (14) and 68.65 (14)°. The crystal structure features inter­molecular N—H⋯O, O—H⋯O and O—H⋯N hydrogen bonds

Achieving hip fracture surgery within 36 hours: an investigation of risk factors to surgical delay and recommendations for practice

BACKGROUND: The UK hip fracture best practice tariff (BPT) aims to deliver hip fracture surgery within 36 h of admission. Ensuring that delays are reserved for conditions which compromise survival, but are responsive to medical optimisation, would help to achieve this target. We aimed to identify medical risk factors of surgical delay, and assess their impact on mortality. MATERIALS AND METHODS: Prospectively collected patient data was obtained from the National Hip Fracture Database (NHFD). Medical determinants of surgical delay were identified and analysed using a multivariate regression analysis. The mortality risk associated with each factor contributing to surgical delay was then calculated. RESULTS: A total 1361 patients underwent hip fracture surgery, of which 537 patients (39.5 %) received surgery within 36 h of admission. Following multivariate analyses, only hyponatraemia was deduced to be a significant risk factor for delay RR = 1.24 (95 % CI 1.06-1.44). However, following a validated propensity score matching process, a Pearson chi-square test failed to demonstrate a statistical difference in mortality incidence between the hypo- and normonatraemic patients [χ (2) (1, N = 512) = 0.10, p = 0.757]. CONCLUSIONS: Hip fracture surgery should not be delayed in the presence of non-severe and isolated hyponatraemia. Instead, surgical delay may only be warranted in the presence of medical conditions which contribute to mortality and are optimisable. LEVEL OF EVIDENCE: III

The Bianchi IX model in Loop Quantum Cosmology

The Bianchi IX model has been used often to investigate the structure close to singularities of general relativity. Its classical chaos is expected to have, via the BKL scenario, implications even for the approach to general inhomogeneous singularities. Thus, it is a popular model to test consequences of modifications to general relativity suggested by quantum theories of gravity. This paper presents a detailed proof that modifications coming from loop quantum gravity lead to a non-chaotic effective behavior. The way this is realized, independently of quantization ambiguities, suggests a new look at initial and final singularities

MANAGEMENT PRACTICES AND LEASE ARRANGEMENTS USED BY OKLAHOMA WHEAT, WHEAT PASTURE, AND WHEAT PASTURE LIVESTOCK PRODUCERS

Winter wheat is grown for three purposes in the Southern Plains, grain-only, forage-only, and as a dual-purpose forage plus grain crop. The USDA's wheat cropping practices survey does not differentiate among the three uses. Little information on actual production practices across use is available. Results of a survey are presented.Crop Production/Industries,

cis-Bis[4-amino-N-(pyrimidin-2-yl)benzene­sulfonamido-κ2 N,N′]bis­(dimethyl sulfoxide-κO)cadmium

The complete mol­ecule of the title compound, [Cd(C10H9N4O2S)2(C2H6OS)2], is completed by the application of a twofold rotation axis. The CdII atom is six coordinated by two bidentate sulfadiazinate anions and two dimethyl­sulfoxide mol­ecules. The resulting N4O2 donor set displays a distorted trigonal–prismatic coordination geometry. The S atom and methyl groups of dimethyl­sulfoxide are disordered over two sets of sites, with site occupancies of 0.715 (4) and 0.285 (4). The crystal structure features inter­molecular N—H⋯N and N—H⋯O hydrogen bonds that lead to the formation of layers in the ab plane

Monotone Grid Drawings of Planar Graphs

A monotone drawing of a planar graph $G$ is a planar straight-line drawing of $G$ where a monotone path exists between every pair of vertices of $G$ in some direction. Recently monotone drawings of planar graphs have been proposed as a new standard for visualizing graphs. A monotone drawing of a planar graph is a monotone grid drawing if every vertex in the drawing is drawn on a grid point. In this paper we study monotone grid drawings of planar graphs in a variable embedding setting. We show that every connected planar graph of $n$ vertices has a monotone grid drawing on a grid of size $O(n)\times O(n^2)$, and such a drawing can be found in O(n) time
