Taxonomic distinctness and species richness as measures of functional structure in bird assemblages

Most traditional "biodiversity" indices have an uncertain ecological interpretation, unfavourable sampling properties, and excessive data requirements. A new index of taxonomic distinctness (the average evolutionary distance between species in an assemblage) has many advantages over traditional measures, but its ecological interpretation remains unclear. We used published behavioural species data

Two-dimensional conformation-dependent electrophoresis (2D-CDE) to separate DNA fragments containing unmatched bulge from complex DNA samples

DNA fragments containing mispaired and modified bases, bulges, lesions and specific sequences have altered conformation. Methods for separating complex samples of DNA fragments based on conformation but independent of length have many applications, including (i) separation of mismatched or unmatched DNA fragments from those perfectly matched; (ii) simultaneous, diagnostic, mismatch scanning of mul

A simple method for reconstructing a high-quality NDVI time-series data set based on the Savitzky-Golay filter

Although the Normalized Difference Vegetation Index (NDVI) time-series data, derived from NOAA/AVFIRR, SPOT/VEGETATION, TERRA or AQUA/MODIS, has been successfully used in research regarding global environmental change, residual noise in the NDVI time-series data, even after applying strict pre-processing, impedes further analysis and risks generating erroneous results. Based on the assumptions tha

Clinical measures of islet function: usefulness to characterize defects in diabetes.

In healthy individuals, the ability of the pancreatic islets to sense and respond appropriately to changes in plasma glucose levels maintains plasma glucose levels within a narrow range despite broad fluctuations in nutrient intake and variable "demand" for insulin imposed by changes in insulin sensitivity. This ability of the pancreatic islets is lost in type 2 diabetes (T2DM). For studies on the

The physiotherapy clinical outcome variables scale predicts length of hospital stay, discharge destination and future home facility in the acute comprehensive stroke unit.

OBJECTIVE: The aims of this study were: to follow the course of recovery of motor function following acute stroke, as assessed by the Physiotherapy Clinical Outcome Variables Scale (COVS), and; to investigate the ability of this instrument to predict length of hospital stay, discharge destination and future home facility. METHODS: In this prospective longitudinal study, COVS was registered at admi

Dynamical effects in X-ray spectra and the final-state rule

The dynamical theory of X-ray spectra due to Nozieres and De Dominicis (ND, 1969) is evaluated here numerically for numerous model systems including cases where the core-hole potential possesses a bound state. It is shown that the resulting emission spectra obey the final-state rule rather accurately. An approximate but analytical derivation of this rule is given which provides insight into the me

Characteristics of Mult-Nozzle Impactors with 50 µm Laser-Drilled Nozzles

The objective of this study was to provide data for the design of multi-nozzle impactors giving size-fractionated samples for X-ray emission analysis and for size-distribution determinations of the α-particle activity from aerosol-particle-attached radon progenies. Different multi-nozzle impactors with laser-drilled 50–60 μm diameter nozzles designed for a cut-off diameter of about 0.05 μm were ex

Inadequate timing of prophylactic antibiotics in orthopedic surgery. We can do better.

BACKGROUND AND PURPOSE: There are rising concerns about the frequency of infection after arthroplasty surgery. Prophylactic antibiotics are an important part of the preventive measures. As their effect is related to the timing of administration, it is important to follow how the routines with preoperative prophylactic antibiotics are working. METHODS: In 114 consecutive cases treated at our own un

Free Energy and Surface Forces in polymer systems: Monte Carlo Simulation Studies

The thesis is focused on two major subjects: - Calculation of free energy is of great help in the study of any molecular system. The free energy determines phase behaviour of colloids and polymer solutions. It also controls the conformational properties of single macromolecules, e.g. DNA, proteins, copolymers. One of the most robust computer simulation techniques for free energy estimation is an

Performance analysis of the improved seeing limited mode for the Euro50

This paper presents an analysis of the point-spread functions (PSFs),which may be expected in the so-called improved seeing limited mode forthe Euro50 (Extremely large telescope with a 50 m aperture). This modecomprises adaptive control of the deformable secondary mirror of theaplanatic Gregorian telescope configuration using guide stars in a widefield. I may result in efficient compensation of tu

Multi-objective performance assessment of wastewater treatment plants combining plant-wide process models and life cycle assessment

Multi-objective performance assessment of operational strategies at wastewater treatment plants (WWTPs) is a challenging task. The holistic perspective applied to evaluation of modern WWTPs, including not only effluent quality but also resource efficiency and recovery, global environmental impact and operational cost calls for assessment methods including both on- and off-site effects. In this stu

Socio-ecological factors determine crop performance in agricultural systems

Agricultural production systems are affected by complex interactions between social and ecological factors, which are often hard to integrate in a common analytical framework. We evaluated differences in crop production among farms by integrating components of several related research disciplines in a single socio-ecological analysis. Specifically, we evaluated spring barley (Hordeum vulgare, L.)

Far-Field-Based Nonlinear Optimization of Millimeter-Wave Active Antenna for 5G Services

This paper presents the design and characterization of millimeter-wave (28/38 GHz), circularly polarized (CP) active antennas, suitable for the future 5G services. By augmenting the modelling capabilities of commercially available nonlinear CAD tools, the active antenna design can simultaneously optimize figures of merits for both radiation and non-linear (NL) performance. The radiating part is co

Adsorption of cadmium by a high-capacity adsorbent composed of silicate-titanate nanotubes embedded in hydrogel chitosan beads

In this study, we developed a nanoparticle-based mesoporous composite that consisted of silicate-titanate nanotubes (STNTs) supported in hydrogel chitosan beads (STNTs-Ch beads) and was studied for Cd2+ adsorption. By using Fourier-transform infrared spectroscopy, transmission and scanning electron microscopy coupled to an energy-dispersive X-ray spectrometer, we coulddetermine that the hollow STN

Pathways for agro-bioenergy transition in Ukraine

Economies in transition (EiTs) (e. g. Ukraine (UA), Belarus, Moldova, etc.) are signifi cantly dependent on energy imports, and require revitalization of their agricultural sectors and improvements in the state of the environment. Development of national bioenergy potentials can contribute to the solutions to these problems. However, EiTs face technical, political, fi nancial, and capacity-based c

Discursive mechanisms and human agency in language policy formation : negotiating bilingualism and parallel language use at a Swedish university

In the wake of the enactment of Sweden’s Language Act in 2009 and in the face of the growing presence of English, Swedish universities have been called upon by the Swedish Higher Education Authority to craft their own language policy documents. This article focuses on the discursive negotiation of institutional bilingualism by a language policy committee at one Swedish university during the proces
