Metabolic impacts of climate change on marine ecosystems: Implications for fish communities and fisheries

Aim:Climate change will reshape marine ecosystems over the 21st century through diverse and complex mechanisms that are difficult to assess quantitatively. Here, we characterize expectations for how marine community biomass will respond to the energetic consequences of changes in primary production and temperature-dependent metabolic rates, under a range of fishing/conservation scenarios. Location: Global ocean. Time period: 1950-2100.Major taxa studied: Commercially harvested marine ectotherms ('fish'). Methods: We use a size-structured macroecological model of the marine ecosystem, coupled with a catch model that allows for calibration with global historical data and simulation of fishing. We examine the four energetic mechanisms that, within the model framework, determine the community response to climate change: net primary production, phytoplankton cell size, and the temperature dependencies of growth and natural mortality. Results: Climate change decreases the modelled global fish community biomass by as much as 30% by 2100. This results from a diminished energy supply to upper trophic levels as photosynthesis becomes more nutrient limited and phytoplankton cells shrink, and from a temperature-driven increase of natural mortality that, together, overwhelm the effect of accelerated somatic growth rates. Ocean circulation changes drive regional variations of primary production, producing patterns of winners and losers that largely compensate each other when averaged globally, whereas decreasing phytoplankton size drives weaker but more uniformly negative changes. The climate impacts are similar across the range of conservation scenarios but are slightly amplified in the strong conservation scenarios owing to the greater role of natural mortality. Main conclusions: The spatial pattern of climate impacts is mostly determined by changes in primary production. The overall decline of community biomass is attributed to a temperature-driven increase of natural mortality, alongside an overall decrease in phytoplankton size, despite faster somatic growth. Our results highlight the importance of the competition between accelerated growth and mortality in a warming ocean.
Effectiveness of nanoatrazine in post-emergent control of the tolerant weed Digitaria insularis

Digitaria insularis (sourgrass) is a monocotyledon weed of difficult control and high invasive behavior. Atrazine is widely applied in the Americas to control weeds in maize culture, but its efficiency against D. insularis is limited. The incorporation of atrazine into poly(epsilon-caprolactone) nanocapsules increased the herbicidal activity against susceptible weeds; however, the potential of this nanoformulation to control atrazine-tolerant weeds including D. insularis has not yet been tested. Here, we evaluated the post-emergent herbicidal activity of nanoatrazine against D. insularis plants during initial developmental stages. The study was carried out in a greenhouse, using pots filled with clay soil. Plants with two or four expanded leaves were treated with conventional or nanoencapsulated atrazine at 50 or 100% of the recommended dosage (1,000 or 2,000 g ∙ ha−1), followed by the evaluation of physiological, growth, and control parameters of the plants. Compared with conventional herbicide, both dosages of nanoatrazine induced greater and faster inhibition of D. insularis photosystem II activity at both developmental stages. Atrazine nanoencapsulation also improved the control of D. insularis plants, especially in the stage with two expanded leaves. In addition, nanoatrazine led to higher decreases of dry weight of fourleaved plants than atrazine. The use of the half-dosage of nanoatrazine was equally or more efficient in affecting most of the evaluated parameters than the conventional formulation at full dosage. Overall, these results suggest that the nanoencapsulation of atrazine potentiated its post-emergent herbicidal activity against D. insularis plants at initial developmental stages, favoring the control of this atrazine-tolerant weed.

Transcranial sonography of substantia nigra for differential diagnosis of Parkinson's disease and other movement disorders: A Meta-analysis

,ismeta-analysis aimed to evaluate the accuracy of hyperechogenicity of the substantia nigra (SN) for the differential diagnosis of Parkinson’s disease (PD) and other movement disorders. We systematically searched the PubMed, EMBASE, Cochrane Library, and China National Knowledge Infrastructure databases for relevant studies published between January 2015 and May 2020. Eligible articles comparing the echogenicity of the SN between patients with PD and those with other movement disorders were screened, and two independent reviewers extracted data according to the inclusion and exclusion criteria. Statistical analyses were conducted using STATA (version 15.0) (Stata Corporation, College Station, TX, USA), Review Manager 5.3 (Cochrane Collaboration), and Meta-DiSc1.4 to assess the pooled diagnostic value of transcranial sonography (TCS) for PD. Nine studies with a total of 1046 participants, including 669 patients with PD, were included in the final meta-analysis. Our meta-analysis demonstrated that hyperechogenicity of the SN had a pooled sensitivity and specificity of 0.85 (0.82, 0.87) and 0.71 (0.66, 0.75), respectively, for distinguishing idiopathic Parkinson’s disease from other movement disorders. Furthermore, the area under the curve of the summary receiver operating characteristic was 0.94. Transcranial sonography of the SN is a valuable tool for the differential diagnosis of PD and other movement disorders.
The Environmental Potential of Phase Change Materials in Building Applications. A Multiple Case Investigation Based on Life Cycle Assessment and Building Simulation

New materials and technologies have become the main drivers for reducing energy demand in the building sector in recent years. Energy efficiency can be reached by utilization of materials with thermal storage potential; among them, phase change materials (PCMs) seem to be promising. If they are used in combination with solar collectors in heating applications or with water chillers or in chilled ceilings in cooling applications, PCMs can provide ecological benefits through energy savings during the building’s operational phase. However, their environmental value should be analyzed by taking into account their whole lifecycle. The purpose of this paper is the assessment of PCMs at the material level as well as at higher levels, namely the component and building levels. Life cycle assessment analyses are based on information from PCM manufacturers and building energy simulations. With the newly developed software “Storage LCA Tool” (Version 1.0, University of Stuttgart, IABP, Stuttgart, Germany), PCM storage systems can be compared with traditional systems that do not entail energy storage. Their benefits can be evaluated in order to support decision-making on energy concepts for buildings. The collection of several case studies shows that PCM energy concepts are not always advantageous. However, with conclusive concepts, suitable storage dimensioning and ecologically favorable PCMs, systems can be realized that have a lower environmental impact over the entire life cycle compared to traditional systems.
Experimental Assessment on Air Clearance of Multiple Valve Unit Considering Switching Impulse and DC Superimposed Switching Impulse

Multiple valve unit (MVU), which converts AC to DC and DC to AC, is one of the key elements of high voltage DC (HVDC) transmission. Therefore, the insulation design of MVU against overvoltage should be considered for the stable and reliable operation of HVDC transmission system. Especially, the air clearance of MVU should be calculated based the switching impulse, since it is fatal to MVU in terms of electrical insulation. However, the previous studies were limited to wave front, and the air clearance of the switching impulse is specified only for an ultra-high voltage (UHV) above 750 kV. As a result, it is difficult to calculate the air clearance of MVU which must endure for a switching impulse under 750 kV. In addition, when the switching impulse introduced while the MVU is in normal operation, it is superimposed to DC and creates the most severe situation, but the studies on such subjects are also insufficient. Therefore, as a fundamental step to calculate the air clearance of MVU, the dielectric characteristics of switching impulse and DC superimposed switching impulse in air have been investigated. The experiments on switching impulse showed that the critical flashover voltage was varied according to the curvature of electrode in the gap distance, up to eight times of the electrode radius. However, beyond that gap distance, the critical flashover voltage became similar, regardless of the radius of electrodes. In case of the superimposed experiment, it was performed according to DC pre-stress level and the polarities of switching impulse. The results were most severe when the positive switching impulse was superimposed on the positive DC, and the peak voltage at which flashover occurs was independent of DC pre-stress.

Evaluating an inclusive blended learning environment in EFL: a flipped approach

Abstract This research explores the use of an inclusive blended learning environment in an EFL class. A total of 39 students, including 6 participants who suffered from physical and cognitive disabilities followed a flipped learning model over a period of two months. In order to create this inclusive blended learning model, a series of videos were developed to deliver three B1 didactic units of an English coursebook and were designed to take into consideration students’ physical and cognitive disabilities. Captions, text and sign language were provided together with the videos, following a “universal design” in which a wide range of students are considered when elaborating the materials. These videos were viewed by participants before their lessons in order for the teacher to devote in-class time to those learners who may have struggled to understand and put into practice the contents and explanations in the videos. In-depth interviews, a perception scale of the flipped learning experience and an evaluation of the tools implemented were used with a special focus on those students with disabilities. Several implications and pedagogical recommendations were drawn.

Small parts of esophagus and cardiac muscles of abattoir sheep from Qena, Upper Egypt between June 2016 to May 2017 were examined by both light microscope (LM), transmission electron microscope (TEM), and DNA sequence analysis of 18 S rRNA gene to determine the rate of infection with Sarcocystis spp. and identify the parasite according to morphological, ultrastructure characteristics, and DNA sequence analysis. LM and TEM studies revealed that microscopic, thin walled sarcocysts were detected in 47 of 63 male (74.6 %) and in 32 of 41 female (65.07 %) as a spindle-shaped with size (225 – 431.3 μm x 34.7- 82.4 μm) in esophagus muscles, and ovoid with size (141.6- 263 μm x 51.4- 82.3 μm) in cardiac muscles. The result sequences were compared with other previously sequenced Sarcocystis species retrieved from Gene Bank it was most closely refered to Sarcocystis tenella (identity 99- 100%).
Estandarizacion de un instrumento de evaluacion multidimensional en los trastornos adictivos

La dependencia de sustancias psicoactivas se asocia a un conjunto de problemas en distintas areas de funcionamiento del sujeto. La "dependencia" y los "problemas" conforman los dos ejes basicos de los transtornos adictivos. Los instrumentos de evaluacion multidimensional tienen por objeto la medida de los problemas relacionados con el consumo. Entre ellos, el addiction severity index (asi) de mclellan y cols. (1980; 1981; 1992), y el opiate treatment index (oti) de darke y cols. (1992), han demostrado su utilidad y validez. Sin embargo, hasta el momento no habian sido validados en nuestro pais. En este trabajo se contribuye a la estandarizacion de la version espanola del a.S. I. Y el o.T. I. Los datos encontrados, tras analizar la consistencia interna, los componentes principales, la fiabilidad test-retest i inter-examinadores, asi como la validez concurrente de cada escala, apoyan la validez de estas versiones. La utilidad de estos instrumentos en la clinica y en la evaluacion de programas esta suponiendo un creciente interes en la investigacion sobre sus parametros psicometricos.

This study seeks to expand the research on the CA of female hotel employees by identifying the factors that influence their CA.
Performance Measures to Assess the Success of Contemporary Science Parks

Although the science park (SP) concept is more than 50 years old, it has been continuously evolving and changing and new doubts, questions and needs have come to light. In order to understand and talk about the future of SPs, it seems necessary to understand their actual level of success. It is not a straightforward task as SPs are multi-owner organisations and definition of success will vary from one SP to another. Moreover, SPs have developed new roles and activities that are not easy to measure. Thereby, the aim of this paper is to fill in the gaps that exist in the literature on measuring the extent of success of contemporary SPs as individual organisations providing support for the benefit of its community. The paper proposes to measure SP success by means of a performance measurement system (pms). It offers a theory grounded tool to assess the effectiveness of SP actions and activities including knowledge-based activity. Additionally, the paper provides some strong evidence that SPs show characteristics in common with knowledge intensive organisations (kios) and therefore play an important role in orchestrating innovation ecosystems.
Classical Drug Serratia Marcescens L-Asparaginaseand Anticancer Activity In Vitro

The present study aimed to production of L-asparaginase from spiny cactus peel waste extract (SCPWE) by submerged cultures of Serratia marcescens. S. marcescens grew well for 180h in SCPWE containing medium, revealed the presence of enough carbohydrate source for growing S. marcescens and production of Asparaginase. Different parameters, such as pH [1,2], temperature and incubation period, were optimized for growth and maximum L-asparaginase production. The optimum culture parameters were 30ì 60h and pH 8.6. Maximum L-asparaginase and biomass were observed at the end of the logarithmic phase (6.4 IU/ml and 2.96g%, respectively). L-asparaginase activity and biomass were increased from 1.4IU/ml and 0.56g% to 6.4 IU/ml and 2.96 g% respectively at the end of logarithmic phase (60h). Higher yields of L-asparaginase (6.4IU/ml) with a specific activity of 1984IU/ml (89-fold purification with 39 % recovery) were obtained from S. marcescens cultures. The purified L-asparaginase was used for the characterization and general properties were used such as effect of pH and temperature as well as stability at pH and temperature on L-asparaginase activity.
Crypt analyzing and Image Encryption Using WU’s Algorithm

In this modern world, images are widely used in different processes. Therefore, the security of image and data from unauthorized uses is important. Now, information security is becoming increasingly important in data storage and broadcasting. It is essential for securing image, either in transit or store on devices. However, some image encryption algorithms still have many security issues and can be easily attacked by attackers. This proposed system performs the cryptanalysis of a newly proposed color image encryption scheme using Wu’s algorithms. For encryption scheme, usually uses a pseudo-random encryption key generated by an algorithm and which makes the image more secure. An authorized beneficiary can easily decrypt the message with the secret key provided by the originator to beneficiary but not to unauthorized users
The complete mitochondrial genome sequence of Halichoeres nigrescens (Labriformes: Labridae)

Abstract The complete mitochondrial genome of marine fish Halichoeres nigrescens was sequenced by the high-throughput sequencing method. The genome is 17,252 bp in length, consisting of 13 protein-coding genes, 22 tRNA genes, two rRNA genes and one large non-coding region. The gene arrangement of Halichoeres nigrescens is identical to that of common fishes. Phylogenetic tree based on 13 protein-coding genes shows that Halichoeres nigrescens has a closer phylogenetic relationship to Macropharyngodon negrosensis than to Halichoeres hartzfeldii.
First chromosome data on Steindachneridion doceanum (Siluriformes: Pimelodidae): a critically endangered catfish endemic of the Doce River basin, Brazil

ABSTRACT The present report represents the first cytogenetic description of Steindachneridion doceanum, great catfish which is currently at high extinction risk and it is listed as threatened on the red list of the Brazilian Ministry of the Environment, also are suggested karyotype relationships with other species of the same genus endemic from other river basins. The results revealed a diploid number of 2n = 56 and the karyotype composed of 18 metacentric, 20 submetacentric, 10 subtelocentric and 8 acrocentric chromosomes (NF = 104). The AgNORs and CMA3 signals were coincident in location occupying the short arm of an acrocentric chromosome pair (25th), in a secondary constriction. The 5S rDNA genes were localized on the short arms of one subtelocentric pair. C-banding revealed terminal blocks on the short arms on many chromosomes as well as terminal positive bands at the both ends of a submetacentric pair. C banding also revealed a large heterochromatic block in the secondary constriction (25th) region that was coincident with the AgNORs sites and CMA3+ bright bands. In spite S. doceanum represent an endemic taxon, in spite their geographic isolation their cytogenetic characteristics show similarities with other species of the genus.
An Autonomic, Adaptive and High-Precision Statistical Model to Determine Bee Colonies Well-Being Scenarios

Honey bees, important pollinators, are threatened by a variety of pests, pathogens and extreme climatic events, such as the winter period. This paper proposes a two-stages model that seeks to define and predict evolutionary scenarios for improving the bee colonies’ well-being. The used dataset has data from both internal and external beehive sensors, and on-site inspection of beekeepers from six apiaries between the years 2016-2018. In the first stage, three evolutionary scenarios were obtained (pessimistic, conservative and optimistic) through the clustering technique. In the second one, aiming to classify these scenarios, an elastic net penalty logistic regression model was obtained with an accuracy of ≈ 99.5%.
Who are the real top scorers: Algorithmically resorting a top scorer list by a limited set of preference assumptions

This article presents an algorithm, which by taking both goals scored as well as matches played into account, is meant to provide “more sensible” top scorer lists in football. The algorithm computes Upper Hulls recursively in order to provide a new and improved list. The complexity of the algorithm is reasonable, and should imply practically feasible execution on a modern computer. The proposed algorithm may also be an interesting alternative to academic scholar ranking. It has interesting properties for instance compared to the h -index.
