TL;DR: The results indicate that environmentally realistic concentrations of atrazine exert a negative impact on amphibian metamorphosis and suggests that mixtures of agricultural chemicals, even if sublethal, may exert negative and not necessarily consistent mixture effects.
Abstract: Tadpoles of the African clawed frog (Xenopus laevis) were exposed to sublethal concentrations of atrazine (0, 40, and 320 microg/L) and nitrate (0, 37, and 292 mg/L) from feeding stage to metamorphosis. A 3 x 3 factorial design was used to identify both single and interactive effects. At metamorphosis, tadpole weight, snout-vent length (SVL), and hematocrit were determined. Mean mortality was greater in tanks receiving 320 microg/L atrazine; nitrate had no effect on mortality. Significant differences for all mean traits at metamorphosis occurred among atrazine treatments; higher atrazine exposure increased time to metamorphosis and decreased weight, SVL, and hematocrit. Nitrate treatments were not significantly different. Significant interaction tests between atrazine and nitrate occurred for weight and SVL at metamorphosis; the specific type of interaction varied among treatments. Assuming an additive mixture model, at low atrazine (40 microg/L), the addition of 37 mg/L nitrate produced SVL values less than expected (a synergistic effect) while the addition of 292 mg/L nitrate yielded SVL values greater than expected (an antagonistic effect). A similar response was noted for tadpoles in the 320-microg/L atrazine treatments. These results indicate that environmentally realistic concentrations of atrazine exert a negative impact on amphibian metamorphosis. Also, this study suggests that mixtures of agricultural chemicals, even if sublethal, may exert negative and not necessarily consistent mixture effects.

TL;DR: The purpose of this commentary is to describe the multifactorial relationships between hip-joint strength, range of motion, kinetics/kinematics, and various knee pathologies, specifically as they relate across an individual's life span.
Abstract: The purpose of this commentary is to describe the multifactorial relationships between hip-joint strength, range of motion, kinetics/kinematics, and various knee pathologies, specifically as they relate across an individual's life span. Understanding the interdependence between the hip and knee joints in respect to functional activity is a necessary and relevant aspect for clinicians to investigate to ameliorate various pathological presentations at the knee that might have a proximal relationship.

TL;DR: In this mode, one or more chiral selectors are added to the background electrolyte acting as pseudostationary phases as mentioned in this paper, and they are applied to enantioseparations in capillary electrokinetic chromatography.
Abstract: Capillary electrokinetic chromatography is generally recognized as a versatile and robust capillary electromigration technique for the separation of enantiomers. In this mode, one or more chiral selectors are added to the background electrolyte acting as pseudostationary phases. Within the various chiral selectors that have been applied to enantioseparations in capillary electrokinetic chromatography, cyclodextrins are by far the most often used selectors because of their versatility, structural variety and commercial availability. This is reflected in the large number of applications of cyclodextrins to analytical enantioseparations that have been reported between January 2012 and July 2016, the period of time covered by this review. Many of these applications cover aspects of life sciences such as drug analysis, bioanalysis or food analysis. Despite the large number of commercially available cyclodextrins, new derivatives have been developed in order to achieve altered enantioselectivities or to further broaden the application range. Cyclodextrins have also been used to demonstrate the validity of theoretical models of electromigration as well as complex formation equilibria in enantioseparations. Finally, recent studies for an understanding of the molecular basis of the chiral recognition between cyclodextrins and the analytes are discussed.

TL;DR: The test results indicated that the carbonized PAN nanofibers have superior physical properties, which may be useful for structural health monitoring (SHM) applications in different industries.
Abstract: This paper presents an idea of using carbonized electrospun Polyacrylonitrile (PAN) fibers as a sensor material in a structural health monitoring (SHM) system. The electrospun PAN fibers are lightweight, less costly and do not interfere with the functioning of infrastructure. This study deals with the fabrication of PAN-based nanofibers via electrospinning followed by stabilization and carbonization in order to remove all non-carbonaceous material and ensure pure carbon fibers as the resulting material. Electrochemical impedance spectroscopy was used to determine the ionic conductivity of PAN fibers. The X-ray diffraction study showed that the repeated peaks near 42° on the activated nanofiber film were α and β phases, respectively, with crystalline forms. Contact angle, thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and Fourier transform infrared spectroscopy (FTIR) were also employed to examine the surface, thermal and chemical properties of the carbonized electrospun PAN fibers. The test results indicated that the carbonized PAN nanofibers have superior physical properties, which may be useful for structural health monitoring (SHM) applications in different industries.

TL;DR: This work takes a comprehensive look at wireless security in the smart-meter-based home area network scenario and identifies possible vulnerabilities, and some countermeasures are developed that can be used by both the utility company and the customer and are integrated into a common framework called SecureHAN that could be agreed to by both.
Abstract: Compared to the conventional grid, the smart grid requires active participation of consumers to improve the quality and reliability of power delivery. The increase in consumer participation is expected from the advanced metering infrastructure (AMI), commonly known as the smart meter, which has the capability of supporting various functions beyond that of recording energy usage. One of the primary objectives of the AMI is to allow load and cost management for the utility. This is envisioned partly through a communication system implemented between the smart meter and consumer equipment, currently deployed using wireless networking solutions such as ZigBee. Due to the shared nature of the wireless medium, however, these deployments face security challenges and interference issues, which must be addressed, taking into account the interests of both the utility company and the consumer. This work takes a comprehensive look at wireless security in the smart-meter-based home area network scenario and identifies possible vulnerabilities. Subsequently, some countermeasures are developed that can be used by both the utility company and the customer and are integrated into a common framework called SecureHAN that can be agreed to by both. In addition, the experiences from implementing the SecureHAN framework using commercial off-the-shelf hardware are described, including possible challenges.
