On the distinct drag, reconfiguration and wake of perforated structures

Using especially designed laboratory experiments, we demonstrate that the flow-driven deformation of sufficiently porous, wall-mounted, flexible plates can exhibit positive Vogel exponent $V$, i.e. drag proportional to the $(2+V)$ power of the incoming flow velocity. High-resolution force balance, planar particle image velocimetry and particle tracking velocimetry are used to measure the drag force, flow characteristics and plate bending. For a flexible plate with relatively high porosity given by an array of regularly spaced square openings, we derive a simple analytical argument that accounts for the sub-quadratic trends of the drag in a range of flow velocities spanning one order of magnitude. There, the drag experienced by the structure is modulated by the contributions of the local structure containing an open area. The effective approach velocity for each of these sections appears to increase monotonically with increased structure deformation due to the reduced effect of local wakes produced by adjacent areas. The uncovered aerodynamic behaviour may help to understand the complex flow–structure interaction of perforated structures in nature and engineering.
Fingerprint Localization With Adaptive Area Search

A new set of complete fingerprints positioning algorithm is proposed in this letter. Firstly, a new criterion that converts the RSS difference between reference points and test point into a relative ranking is proposed to select one reference point with highest similarity to the test point. Secondly, <inline-formula> <tex-math notation="LaTeX">${k}$ </tex-math></inline-formula> reference points with higher similarity are adaptively selected by this criterion and an adaptive area search algorithm based on region growing, then the inverse of each reference point ranking is adopted as their own weight. Finally, the coordinates of <inline-formula> <tex-math notation="LaTeX">${k}$ </tex-math></inline-formula> reference points are weighted average to obtain the positioning result. Extensive experimental results show that the proposed algorithm can effectively improve the positioning accuracy.
Laboratory Characterization of a Compacted–Unsaturated Silty Sand with Special Attention to Dynamic Behavior

The dynamic properties of compacted non-cohesive soils are desired not only because of the risk of natural sources of dynamic excitations such as earthquakes, but mostly because of the anthropogenic impact of machines that are working on such soils. These soils are often unsaturated, which positively affects the soil’s mechanical properties. The information about the values of these parameters is highly desirable for engineers. In this article, we performed a series of tests, including oedometric tests, resonant column tests, bender element tests, and unsaturated triaxial tests, to evaluate those characteristic parameters. The results showed that sandy silt soil has a typical reaction to dynamic loading in terms of shear modulus degradation and the damping ratio curves’ characteristics, which can be modeled by using empirical equations. We found that the compaction procedure caused an over-consolidation state dependent on the moisture content during compaction effort. The article analyzed the soil properties that impact the maximum shear modulus G0 value. Those properties were suction s, confining pressure σ3, and compaction degree represented by the void ratio function f(e).

Design optimization and comparison of linear magnetic actuators under different topologies

In this study, several types of linear actuators that adopt different permanent-magnet (PM) topologies are studied and compared. These linear actuators are based on the concept of PM magnetic screw transmission, which offers high force density, high reliability, and overload protection. Using different magnetic configurations and assembly methods, these linear actuators are designed and optimized for a fair comparison. Initially, based on the operating principle and maximum thrust force, the surface-mounted magnetic screw is described and optimized. Furthermore, the embedded magnetic screw, Halbach array magnetic screw, and field modulated magnetic screw are investigated and compared. Their electromagnetic performances, such as thrust force, torque, magnetic losses, and demagnetization effects are analytically assessed and verified using finite-element analysis. Finally, a prototype of the surface-mounted magnetic screw is developed to validate the predictions.
Variability in PM2.5 and meteorological effects on their mass concentrations over Fuzhou, China during 2014-2016

Simultaneous measurements of mass concentrations of PM2.5 along with other co-existence pollutants viz., SO2, CO, NO2 and O3, were studied with hourly datasets and the data of meteorological conditions were measured per 3 hours from 1st Sep 2014 to 30th Sep 2016 at Fuzhou city, China. The concentration of PM2.5 is 28.42 ± 14.75 in the study period. Meanwhile, the seasonal ratio of PM2.5 was also analysed, with the maximal value as 0.61 in winter, 0.52 in spring, 0.49 in autumn and 0.44 in summer. This implied that fine particulate reaches the maximal value in winter and the minimum value in summer. The correlation coefficient between concentrations of PM2.5 and SO2, CO, NO2, and O3 concentrations were 0.64, 0.52, 0.53 and 0.67. There existed negative correlation between PM2.5 and T (– 0.27), HCC (– 0.13), WS (– 0.16), VIS (– 0.46), DT (-0.31) and RF (-0.10). Subsequently, the impacts of typhoons on the mass concentrations of PM2.5 during September 10th 2016 to September 16th 2016 were analyzed during which the mass concentration of PM2.5 decreased at a large extent and the fine particulates have more prominent changes during the typhoon period compared with coarse particulates.
Selective and Differential Medium for Isolation of Listeria monocytogenes from Foods.

Hemolytic ceftazidime lithium chloride agar (HCLA) has been developed as a selective and differential plating medium for the isolation of Listeria monocytogenes from fishery products. Selectivity is based upon lithium chloride, colistin methane sulfonate, and ceftazidime. When horse blood was incorporated in the agar overlay, L. monocytogenes colonies were easily distinguished by their characteristic blue-gray color surrounded by narrow zones of ß-hemolysis. Listeria innocua , a species commonly present in foods, does not produce hemolysis on the medium. Therefore, one or more colonies of L. monocytogenes were easily distinguished from large populations of L. innocua . When used in combination with Food and Drug Administration and U.S. Department of Agriculture enrichment methodology, HCLA was effective in inhibiting competitive organisms, differentiating colonies of L. monocytogenes by their ß-hemolysis, and shortening the incubation time at 35°C for presumptive identification to 17-24 h.

Adding value to a recalcitrant and problematic waste: the use of dog hair for fungal keratinolytic protease production

Abstract The demand for keratinolytic proteases has increased in recent years, in view of their applications in the feed, detergent, fertilizer, leather and textile industries. Recently, studies have focussed on exploration of new and inexpensive carbon sources for their production. Among keratin wastes, dog hair presents no utility and is an environmental concern. In this study, we evaluate the feasibility of using white and melanized dog hair (WDH and MDH, respectively) as alternative substrates for protease production by a Fusarium oxysporum strain. The effects of dog hair concentration, cultivation period, and medium pH on alkaline protease production were investigated using a central composite rotary design (CCRD) and response surface methodology (RSM). The optimization process increased protease activity 14.85- and 7.19-fold, using WDH and MDH, respectively. The alkaline proteases produced from WDH and MDH showed distinct biochemical characteristics. To our knowledge, this is the first report on biotechnological use of this problematic, waste residue. Our results open new avenues for conversion of dog hair into other valuable products, especially feed or fertilizer. Graphical Abstract

Structural and Chemical Modifications of Carbon Dioxide on Transport to the Deep Earth

The structural and chemical changes to which carbon dioxide is subjected with increasing pressure and temperature are discussed here with the purpose of following the modifications of this important geochemical material on proceeding from the Earth’s surface down to the core‐mantle boundary. The relevance of metasta-bilities, and then of kinetic controlled transformations, is evidenced in the P‐T ranges characteristic of both molecular phases and extended covalently bonded structures. From a chemical point of view, this analysis high-lights how the characterization of the melting of the extended structures would represent an important step to understand the role of this compound in the chemistry of the Earth’s mantle.
Learning Geometric Features with Dual–stream CNN for 3D Action Recognition

Recently, regarding several beneficial properties of depth camera, numerous 3D action recognition frameworks have studied high-level features by exploiting deep learning techniques, but nevertheless they cannot seize the meaningful characteristics of static human pose and dynamic action motion of a whole sequence. This paper introduces a deep network configured by two parallel streams of convolutional stacks for fully learning the deep intra-frame joint associations and inter-frame joint correlations, wherein the structure of each stream is learned from Inception-v3. In experiments, besides the compatibility verification with various backbone networks, the proposed approach achieves the state-of-theart performance in battle with several deep learning-based methods on the updated NTU RGB+D 120 dataset.
In vitro development competence of bovine nuclear transfer embryos derived from nanog-overexpressing fibroblast cells.

Received: Revised: Accepted: January 18, 2013 April 27, 2013 July 2, 2013 The purpose of this study was to establish Nanog-expressing cell lines that can be used as donor cells to construct transgenic cloned embryos, and to investigate their in vitro development competence. By reverse transcription-polymerase chain reaction (RT-PCR), the cDNA of Nanog gene was cloned from fetal bovine primordial genital ridge tissues. The gene was inserted into PMD18-T vector using recombination techniques and then subcloned into vector pEGFP-C1. After confirmation by restrictive endonuclease digestion and sequencing, the recombinant plasmid pEGFP-Nanog was transfected into skin fibroblast cells. A stable transfected cell line was successfully established after two months of selection with neomycine (G418). Fluorescence microscopy, RT-PCR, and Western Blotting assays indicated that Nanog mRNA and EGFP-Nanog fusion protein were expressed in these cells. The EGFP-Nanog expressing fibroblast cells and the intact fibroblast cells (BEF422) were respectively used to construct cloned embryos. The results showed that the cleavage rate of recombinant embryos in BEF422 cells was significantly (P<0.05) higher than in EGFP-Nanog expressing cells (82.14 vs 40.38%), but the blastocyst development rate in the latter was slightly higher than in the former (17.30 vs 14.29%) (P<0.05), indicating that Nanog-overexpressed fibroblasts may be a better candidate of donor cells. To our knowledge, this is the first time that Nanog gene has been introduced into fibroblast cells to produce cloned embryos in bovine. ©2013 PVJ. All rights reserved
Investigating the effects of melatonin and resveratrol agents on non-alcoholic fatty liver disease

Non-alcoholic fatty liver disease (NAFLD) is one of the common liver diseases. Diagnosing and investigating the effect of substances used in treating this disease are performed by experts who examine histopathological tissue sections under microscope. However, this approach is prone to errors and subjective depending on personal experience of the expert. The purpose of this study is: with the help of computer- aided diagnosis systems to investigate the effects of Melatonin and Resveratrol agents on histopathological liver tissue sections damaged by applying carbon tetrachloride (CCl4) composition. The proposed system aims to eliminate the tendency to subjectivity and error by providing information compiled by calculating the rate of fat vacuoles in the form of macrovesicular and microvesicular in hepatocytes and the number of hepatocytes quantitatively to an expert. As a result, an expert can perform objective and quantitative assessment in diagnosing, grading and evaluation of the effects of Melatonin and Resveratrol substances on damaged liver tissue. Keywords: K-Means, CAD, computer aided diagnosis, NAFLD, analysis of histopathological images;
An In-Depth Evaluation of Otolith Zonation and an Ageing Comparison of Otoliths, Scales, and Pectoral Fin Rays of Redband Trout ( Oncorhynchus mykiss gairdneri ) and Bluegill ( Lepomis macrochirus )

Redband Trout (Oncorhynchus mykiss gairdneri), a native subspecies of Rainbow Trout residing east of the Cascade Mountains, USA, are a popular sport fish in much of its range. Bluegills (Lepomis macrochirus) are one the most important recreational fishes in North America, and are also sought by anglers in many Idaho waters. There is extensive confusion surrounding the timing and interpretation of otolith zones, specifically, which zone represents fast growth and which represents slow growth. Further, otoliths are a lethal sampling method and regardless of population status, many fisheries biologists prefer to use no lethal sampling methods. To determine if the zonation confusion is a species-related difference, I calculated monthly growth rates and investigated otolith zonation for a cold-water (Redband Trout) and a warm-water (Bluegill) species, in two Southern Idaho streams and three ponds. I also compared the assigned age and precision of sagittal otoliths, pectoral fin rays, and scales for these two species. Redband Trout showed their fastest growth during the month of June, with continuation of growth through September. The opaque zone started to form in March; by June 100% of the Redband had formed an opaque outer edge on the otolith. As with Redband Trout, the fastest growth rates for Bluegill were during late spring and early summer. This fast growth coincided with the formation of the translucent zone, which was observable in 95% of Bluegill by the month of May. Similar to Redband Trout, 100% of Bluegill had begun forming their fast growth zone by June. Based on edge analysis the otolith zonation pattern for Bluegill is translucent-forming during summer

The Superorganism: The Beauty, Elegance, and Strangeness of Insect Societies

The Pulitzer Prize-winning authors of The Ants render the extraordinary lives of the social insects in this visually spectacular volume. The Superorganism promises to be one of the most important scientific works published in this decade. Coming eighteen years after the publication of The Ants, this new volume expands our knowledge of the social insects (among them, ants, bees, wasps, and termites) and is based on remarkable research conducted mostly within the last two decades. These superorganismsa tightly knit colony of individuals, formed by altruistic cooperation, complex communication, and division of laborrepresent one of the basic stages of biological organization, midway between the organism and the entire species. The study of the superorganism, as the authors demonstrate, has led to important advances in our understanding of how the transitions between such levels have occurred in evolution and how life as a whole has progressed from simple to complex forms. Ultimately, this book provides a deep look into a part of the living world hitherto glimpsed by only a very few.
Antibiotics in aquaculture: reducing their use and maintaining their efficacy

Abstract: The use of antibiotic therapy in aquaculture inevitably leads to the emergence of resistance in the target bacteria and a reduction of the efficacy of this method of disease control. It is argued that a better understanding of the aetiology of aquatic animal diseases and the potential of antibiotics to control disease losses is essential if we are to achieve a more prudent use of this therapy. The ability to detect resistance in target bacteria will be central if we are to use these agents wisely; the methods available to measure bacterial susceptibility are critically analysed.
Effect of artificial warren size on a restocked European wild rabbit population

From the time since the decline of the wild rabbit Oryctolagus cuniculus in southern Europe, various techniques and methods have been explored with a view to restoring wild rabbit populations or increasing rabbit resilience, for both conservation and game purposes. Rabbit restocking and habitat management are among the measures most often applied. Some efforts have been made to increase refuges for wild rabbits, mainly through the construction of artificial warrens. The present study evaluates the response of a wild rabbit population introduced to artificial warrens of varying sizes. This involves comparisons of the density of rabbits in the warrens, rabbit density change between seasons of low and high rabbit population density and the productivity index for large and small warrens in rabbit populations living under semi‐natural conditions. Our results show that large warrens had higher rabbit abundance than had small warrens, but significantly lower rabbit density. No differences in density increase or productivity index were found with respect to warren size. The results suggest that it is preferable to build many small warrens for conservation of wild rabbit populations, but, in the event that only a few warrens are built, it is advisable that they be large.
