Species diversity of the genus Riccia L. (Marchantiales, Ricciaceae) in Maranhão state, Brazil

Ricciaceae is a little-known liverwort family in northeastern Brazil. Fieldwork in 4 localities in Maranhão state yielded 4 species of Riccia, with 2 taxa, R. mauryana and R. weinionis, representing new state records. This paper describes the species diversity of the genus Riccia in Maranhão state, and provides descriptions, ecological notes, and illustrations for each species.

In-hospital care, complications, and 4-month mortality following a hip or proximal femur fracture: the Spanish registry of osteoporotic femur fractures prospective cohort study

SummaryWe have characterised 997 hip fracture patients from a representative 45 Spanish hospitals, and followed them up prospectively for up to 4 months. Despite suboptimal surgical delays (average 59.1 hours), in-hospital mortality was lower than in Northern European cohorts. The secondary fracture prevention gap is unacceptably high at 85%.PurposeTo characterise inpatient care...

Narcolepsy: Pathophysiology and Neuropsychological Changes

Narcolepsy is now recognized as a distinctive disorder with specific pathophysiology and neurochemical abnormalities. Findings on the role of the neuropeptide hypocretin are opening new avenues of research and new strategies for therapy. Recently, neuropsychological and electrophysiological studies have provided evidence for reduced memory performance on standard memory tests in...

4D gauge theories with conformal matter

Abstract One of the hallmarks of 6D superconformal field theories (SCFTs) is that on a partial tensor branch, all known theories resemble quiver gauge theories with links comprised of 6D conformal matter, a generalization of weakly coupled hypermultiplets. In this paper we construct 4D quiverlike gauge theories in which the links are obtained from compactifications of 6D...

A Modified Lindstedt–Poincaré Method for a Strongly Nonlinear System with Quadratic and Cubic Nonlinearities

A modified Lindstedt–Poincaré method is presented for extending the range of the validity of perturbation expansion to strongly nonlinear oscillations of a system with quadratic and cubic nonlinearities. Different parameter transformations are introduced to deal with equations with different nonlinear characteristics. All examples show that the efficiency and accuracy of the...

Comparison of Trigeminal and Postherpetic Neuralgia

Although postherpetic neuralgia and trigeminal neuralgia (tic douloureux) are common causes of facial pain, they have very little in common aside from lancinating pain (other qualities of pain in each disorder are different). Each disorder affects different areas of the face and the treatment of each is quite dissimilar. The pathogenesis of these two disorders quite likely...

Dual upconversion nanophotoswitch for security encoding

Light-harvesting lanthanide ions (Ln3+) doped NaYF4 inks could provide polychromatic patterns for opposing counterfeiting commodity infestation because of their distinctive upconversion photoluminescence (UPL) properties. Herein, three kinds of core-triple-shell Ln3+ ions doped NaYF4 upconversion nanocrystals (UCNCs) are synthesized through modified high-temperature...

The Extreme Climate Event Database (EXCEED): Development of a picture database composed of drought and flood stimuli

The present study introduces the Extreme Climate Event Database (EXCEED), a picture database intended to induce emotionally salient stimuli reactions in the context of natural hazards associated with global climate change and related extreme events. The creation of the database was motivated by the need to better understand the impact that the increase in natural disasters...

The Female of Bertrana Hieroglyphica Petrunkevitch (Araneae, Argiopidae)

Four species of this very interesting genus are known at the present time. Keyserling (1884) established the genus and described the first known species from a group of females from Peras, Brazil. Two other species have been described from South America by Simon (1893); one of these was from Peru and the other from Para, Brazil. Dr. Petrunkevitch was the first to describe a male...

Influenza Infection Screening Tools Fail to Accurately Predict Influenza Status for Hospitalized Patients During Pandemic H1N1 Influenza Season

BACKGROUND: Following the severe acute respiratory syndrome outbreak in 2003, hospitals have been mandated to use infection screening questionnaires to determine which patients have infectious respiratory illness and, therefore, require isolation precautions. Despite widespread use of symptom-based screening tools in Ontario, there are no data supporting the accuracy of these...

Are Navy Weight Management Programs Ensuring Sailor Physical Readiness? An Analysis at Naval Medical Center San Diego

The obesity epidemic in the USA includes active duty service members in the military and effects physical readiness. At the Naval Medical Center San Diego command, the Health & Wellness Department is charged with administering the Weight Management Programs (WMP) for sailors in the San Diego area to ensure military physical readiness requirements. The optimal allocation of...

Glowbal IP: An Adaptive and Transparent IPv6 Integration in the Internet of Things

The Internet of Things (IoT) requires scalability, extensibility and a transparent integration of multi-technology in order to reach an efficient support for global communications, discovery and look-up, as well as access to services and information. To achieve these goals, it is necessary to enable a homogenous and seamless machine-to-machine (M2M) communication mechanism...

Application of decomposition to hyperbolic, parabolic, and elliptic partial differential equations

The decomposition method is applied to examples of hyperbolic, parabolic, and elliptic partial differential equations without use of linearizatlon techniques. We consider first a nonlinear dissipative wave equation; second, a nonlinear equation modeling convectlon-diffusion processes; and finally, an elliptic partial differential equation.

Clinical applications of proton MR spectroscopy in the diagnosis of brain tumours

There are few but important problems in magnetic resonance (MR) diagnosis of the brain tumours such as predicting the grade, exact definition of the tumour borders, differentiation of the cystic tumours from abscess, the tumoral core from peritumoral oedema, and the tumour recurrence from radiation necrosis. MR spectroscopy (MRS) can add more information to MR imaging (MRI) in...

Microwave Assisted Synthesis of Some Biologically Active Benzothiazolotriazine Derivatives

Synthesis of some biologically active benzothiazolotriazine derivatives by microwave irradiation is reported. 2-Amino-6-substituted benzothiazoles 1 on treatment with benzaldehyde in anhydrous ethanol afforded 2-benzylidenoimino-6-substitutedbenzothiazoles 2 which underwent cyclisation with ammoniumthiocyanate in dioxane to give 2-phenyl benzothiazolo [3,2-α]-s-triazine-4-[3H...

Directly grown nanostructured electrodes for high-power and high-stability alkaline nickel/bismuth batteries

Bismuth oxide (Bi2O3) has received great attention as an anode material for alkaline nickel/bismuth (Ni/Bi) batteries due to its high theoretical capacity and easy preparation. However, the generally poor conductivity of metal oxides and the instability of Bi2O3 during cycling severely limit the device performance. Herein, we present the use of directly grown Bi2O3 nanoflake film...

Computing the Number of Induced Copies of a Fixed Graph in a Bounded Degree Graph

In this paper we show that for any graph H of order m and any graph G of order n and maximum degree \(\Delta \) one can compute the number of subsets S of V(G) that induces a graph isomorphic to H in time \(O(c^m \cdot n )\) for some constant \(c = c(\Delta ) >0\). This is essentially best possible (in the sense that there is no \(c^{o(m)}poly(n)\)-time algorithm under the...
