Universally Applicable Model for the Quantitative Determination of Lake Sediment Composition Using Fourier Transform Infrared Spectroscopy
Fourier transform infrared spectroscopy (FTIRS) can provide detailed information on organic and minerogenic constituents of sediment records. Based on a large number of sediment samples of varying age (0-340 000 yrs) and from very diverse lake settings in Antarctica, Argentina, Canada, Macedonia/Albania, Siberia, and Sweden, we have developed universally applicable calibration models for the quant
Growth in Children with Cerebral Palsy during five years after Selective Dorsal Rhizotomy: a practice-based study
Background: Overweight is reported as a side effect of SDR. The aims were to study the development of weight, height and body mass index (BMI) during five years after SDR. Methods: This prospective, longitudinal and practice-based study included all 56 children with CP spastic diplegia undergoing SDR from the start in March 1993 to April 2003 in our hospital. The preoperative Gross Motor Function
The prevalence of adulthood overweight and obesity in Tehran: findings from Urban HEART-2 study.
BACKGROUND:To estimate and compare prevalence of overweight and obesity among adult people across the 22 districts of Tehran in 2011. METHODS:This was a cross-sectional study using data on 47,406 women and 47,525 men aged≥ 15 years from a large population-based survey (Urban HEART-2). Age-standardized prevalence (ASP) of overweight (25≤BMI
Standing on shaky ground: US patent-eligibility of isolated DNA and genetic diagnostics after AMP v USPTO - Part IV
As discussed in the previous issues of QMJIP, the Federal Circuit's decisions in Myriad I-2 and II3 appear to provide considerable prospects for patentees, as clever claim drafting may still help to avoid most patent-eligibility traps set by the much debated US Supreme Court decision in Prometheus.(4) Yet, the split opinions also contain elusive reasoning by each of the three judges. The questions
Poly[dimethyldiphenylphosphonium [di-mu(4)-iodido-tetra-mu(3)-iodido-pentacopper(I)]]
The title compound, {(C14H16P)[Cu5I6]} (n) , prepared from the reaction between copper powder, iodine and dimethyldiphenylphosphonium iodide in hydroxyacetone, features an anion that consists of a continuous two-dimensional Cu-I sheet [Cu-I = 2.5960 (14)-2.6994 (13) A and Cu-I-Cu = 63.28 (5)-114.25 (5)degrees]. The cation, which lies on a mirror plane, is a typical dimethyldiphenylphosphonium ion.
Reversibility of acute intermediate phase bilirubin encephalopathy
Aim: To show the potential for reversing acute intermediate to advanced phase bilirubin encephalopathy. Methods: Case studies. Results: Six extremely jaundiced infants had symptoms of intermediate to advanced phase acute bilirubin encephalopathy. The infants were treated aggressively. Two patients had brain magnetic resonance imaging showing increased signals in the globus pallidus. On follow-up,

Artikeln undersöker hur berättelser om människor och apor, från scala natuae, via evolutionsberättelsen till moderna romaner förhållit sig till konstruktionen av tid och temporalitet - hur exempelvis bilden av tävling mellan människa och apa - där människan tar sig upp och fram, medan apan hamnar på efterkälken, bidragit till idén om progressiv, kronologisk tid, medan andra mer hybridiska berättel
Konfirmandernas bildningsresa
Varje år genomgår mer än en tredje del av alla 15-åringar konfirmandundervisning. Ungdomarna uppskattar konfirmationen - inte minst att planera och genomföra gudstjänster. Men vanliga gudstjänster har de inte så mycket till övers för.
Disease activity level, remission and response in established rheumatoid arthritis: Performance of various criteria sets in an observational cohort, treated with anti-TNF agents
Background: Most composite indices of disease activity and response criteria in RA have been validated and compared in clinical trials rather than routine care. We therefore wanted to compare the performance of the DAS28, SDAI and CDAI activity indices, their activity states, their response criteria, and also compare with the ACR response criteria in an observational clinical setting. Methods: Agr
DNA methylation protects hematopoietic stem cell multipotency from myeloerythroid restriction
DNA methylation is a dynamic epigenetic mark that undergoes extensive changes during differentiation of self-renewing stem cells. However, whether these changes are the cause or consequence of stem cell fate remains unknown. Here, we show that alternative functional programs of hematopoietic stem cells (HSCs) are governed by gradual differences in methylation levels. Constitutive methylation is es
Niche recycling through division-independent egress of hematopoietic stem cells
Hematopoietic stem cells (HSCs) are thought to reside in discrete niches through stable adhesion, yet previous studies have suggested that host HSCs can be replaced by transplanted donor HSCs, even in the absence of cytoreductive conditioning. To explain this apparent paradox, we calculated, through cell surface phenotyping and transplantation of unfractionated blood, that similar to 1-5% of the t
Reactivity of phenyldi(2-thienyl) phosphine towards group 7 metal carbonyls: Carbon-phosphorus bond activation
Addition of phenyldi(2-thienyl) phosphine (PPhTh2) to [Re-2(CO)(10-n)(NCMe)(n)] (n = 1, 2) affords the substitution products [Re-2(CO)(10-n)(PhPTh2)(n)] (1, 2) together with small amounts of fac-[ClRe(CO)(3)(PPhTh2)(2)] (3) (n = 2). Reaction of [Re-2(CO)(10)] with PPhTh2 in refluxing xylene affords a mixture which includes 2, [Re-2(CO)(7)(PPhTh2)(mu-PPhTh)(mu-H)] (4), [Re-2(CO)(7)(PPhTh2)(mu-PPhTh
A Gradient-Enhanced Continuum Damage Model for Residually Stressed Fibre-Reinforced Materials at Finite Strains
The modelling of damage effects in materials constitutes a major challenge in various engineering-related disciplines. However, the assumption of purely local continuum damage formulations may lead to ill-posed boundary value problems and—with regard to numerical methods such as the finite element method—to mesh-dependent solutions, a vanishing localised damage zone upon mesh refinement, and hence
A toxicological and dermatological assessment of alkyl cyclic ketones when used as fragrance ingredients The RIFM Expert Panel
The alkyl cyclic ketone (ACK) fragrance ingredients are a diverse group of structures with Similar metabolic and toxicity profiles. ACK fragrance materials demonstrate low acute toxicity. Upon repeat dose testing, some adverse effects in biochemical and hematological parameters, and slightly increased liver and kidney weights were reported, primarily at high doses, resulting from adaptive effects.
Valence bond liquid phase in the honeycomb lattice material Li2RuO3
The honeycomb lattice material Li2RuO3 undergoes a dimerization of Ru4+ cations on cooling below 270 degrees C, where the magnetic susceptibility vanishes. We use density functional theory calculations to show that this reflects the formation of a valence bond crystal, with a strong structural bond disproportionation. On warming, x-ray diffraction shows that discrete threefold symmetry is regained
Hydrogen intercalation of graphene grown on 6H-SiC(0001)
Atomic hydrogen exposures on a monolayer graphene grown on the SiC(0001) surface are shown to result in hydrogen intercalation. The hydrogen intercalation induces a transformation of the monolayer graphene and the carbon buffer layer to bi-layer graphene without a buffer layer. The STM, LEED, and core-level photoelectron spectroscopy measurements reveal that hydrogen atoms can go underneath the gr

The State of Naming Conventions in R
Most programming language communities have naming conventions that are generally agreed upon, that is, a set of rules that governs how functions and variables are named. This is not the case with R, and a review of unofficial style guides and naming convention usage on CRAN shows that a number of different naming conventions are currently in use. Some naming conventions are, however, more popular
Phosphorus in soil treatment systems : accumulation and mobility
Septic tanks with subsequent soil treatment systems (STS) are a common treatment technique for domestic wastewater in rural areas. Phosphorus (P) leakage from such systems may pose a risk to water quality (especially if they are located relatively close to surface waters). In this study, six STS in Sweden (11-28 years old) were examined. Samples taken from the unsaturated subsoil beneath the distr
