The Cost of Wind: Negative Economic Effects of Global Wind Energy Development

This paper provides a structured literature review of the negative economic effects associated with the development of wind energy and synthesized the evidence at an abstract level. We then developed an analytical framework to systematically review economic issues such as volatility, electricity price, housing values, and unemployment in relation to wind energy. Global wind energy development data from the time period from 2000 through 2019 were included for a more robust analysis. This period encompasses the vast majority of total global installed wind energy capacity. After amalgamating evidence from existing studies and data banks, we discuss the policy implications, suggest avenues for future research, and propose solutions to mitigate externalities. By understanding the negative economic impact created by the expansion of wind energy, we can better equip policy makers and developers to create more efficient and sustainable energy policy to benefit citizens and preserve the environment for generations to come.
Towards high-performance heterogeneous palladium nanoparticle catalysts for sustainable liquid-phase reactions

High-performance supported palladium nanoparticle (Pd-NP) catalysts help to address the growing demand for ‘green’ chemical production processes. At present, literature information on how the NP characteristics, NP–support and support–reactant/product interactions affect the catalytic performance, is scattered. As a result, the present review aims to bring together and critically analyze the relevant literature reports on the catalytic performance of supported Pd-NP catalysts in various liquid-phase reactions such as (de-)hydrogenation, alcohol (electro-)oxidation and cross-coupling reactions. The five main NP support classes, i.e., metal oxides, zeolites, carbon structures, polymers and ordered porous materials, are discussed in detail. A thorough understanding about the catalytic behaviour of supported Pd-NP catalysts via the NP characteristics, NP–support and support–reactant/product interactions give useful insights to optimize current or even create novel NP catalysts for a specific liquid-phase reaction.
Physical and Chemical Characterization of Fog Oil Smoke and Hexachloroethane Smoke

Abstract : The U.S. Army HC smoke generator has been studied, the investigation including the reagent materials, generation process, and the product gases and aerosol smoke. The reagent material consisted of hexachloroethane, zinc oxide, aluminum. In a series of chamber tests, variations in material composition did not appear to affect the characteristics of the product smoke, but small variations in the aluminum concentration did control the rate of the smoke generating reaction.
Mit Ionen ist zu rechnen

Quantencomputer versprechen, spezielle, für Anwendungen hochinteressante Aufgaben zu lösen. An diesen NP‐harten Problemen scheitern herkömmliche Supercomputer. Eine Technik, die intensiv erforscht wird, ist der Ionen‐Quantencomputer. An ihm demonstriert dieser Artikel, wie der Quanten‐Suchalgorithmus von Lov Grover funktioniert. Programmiert werden solche Quantencomputer über einen Software‐Stack. Er übersetzt die Befehle der Nutzeroberfläche über verschiedene Stufen in die Laser‐Manipulation der Ionen‐Qubits. Bei den aktuell in Laboren laufenden Quantencomputern sind etwa zehn Ionen die Grenze, ab der das Rauschen der Quantengatter für zu große Fehler in den Rechnungen sorgt. In Zukunft soll eine Quantenfehlerkorrektur, die mehrere physische Qubits zu einem logischen Qubit verknüpft, Fehler erkennen können. Um die Zahl der Ionen zu steigern, soll die Kontrolle über die Laserpulse und die Fallenpotenziale verbessert werden. Zudem wird daran geforscht, mehrere Ionenfallen zum Beispiel via Photonenverschränkung miteinander zu verbinden. Mikrochip‐Ionenfallen sollen Ionen‐Quantencomputer miniaturisieren.
Transient thermal and static structural analysis of vented disc rotors.

Recent trends and developments in automobile technology have resulted in building safer vehicles, especially considering the braking system, which decelerates the vehicles as per the driver’s requirement within reasonable time. Continuous braking results in excessive heating of the disc rotors, which results in decreasing the braking efficiency which modern cars cannot abide. When brakes are applied, the kinetic energy of vehicles is converted into heat energy, thus if the heat dissipation is not quick enough, it may induce a number of problems such as thermal elastic instability. This work deals with the study of the existing vented disc rotors made of stainless steel using Solidworks and Ansys, to perform transient thermal analysis and structural analysis in five steps for a time period of five seconds. IndexTerms Ansys, Heat flux, Structural Analysis, Transient Thermal Analysis, Vented rotors.

Necessary and Sufficient Second-Order Optimality Conditions on Hadamard Manifolds

This work is intended to lead a study of necessary and sufficient optimality conditions for scalar optimization problems on Hadamard manifolds. In the context of this geometry, we obtain and present new function types characterized by the property of having all their second-order stationary points be global minimums. In order to do so, we extend the concept convexity in Euclidean space to a more general notion of invexity on Hadamard manifolds. This is done employing notions of second-order directional derivatives, second-order pseudoinvexity functions, and the second-order Karush–Kuhn–Tucker-pseudoinvexity problem. Thus, we prove that every second-order stationary point is a global minimum if and only if the problem is either second-order pseudoinvex or second-order KKT-pseudoinvex depending on whether the problem regards unconstrained or constrained scalar optimization, respectively. This result has not been presented in the literature before. Finally, examples of these new characterizations are provided in the context of “Higgs Boson like” potentials, among others.
Finding Clusters of Measurement Invariant Items for Continuous Covariates

ABSTRACT Measurement invariance (MI) cannot always be achieved for the full length of a test or questionnaire, leading researchers to seek for measurement invariant item subsets. Previous approaches either 1) can only analyze group covariates or 2) make implicit assumptions on the nature of MI and then yield a single item set. We provide a general approach for identifying invariant item sets via structural equation modeling that can be applied to dichotomous as well as continuous covariates. It yields multiple item clusters of close measurement invariant items and gives researchers comprehensive insight into the non-MI structure of a test. Furthermore, it allows making well-justified decisions on their assumptions when inferring on group differences or relationships with other variables. The proposed approach performed well in an extensive simulation study. We illustrate the usage and merits of the approach with empirical data on mood states.

The hidden side of sub-supplier firms' sustainability – an empirical analysis

PurposeThe purpose of this paper is to investigate how sub-suppliers decouple the implementation of sustainable supply management practices in supply chains, and what institutional logics permit these suppliers to do so.Design/methodology/approachFollowing a qualitative design, we conducted 23 in-depth semi-structured interviews with owners and managers of apparel sub-suppliers. To corroborate research findings, the views of owners and managers were triangulated by further interviewing 18 key representatives of wide-ranging institutional actors.FindingsThe findings suggest that owners and managers of sub-suppliers use two decoupling responses: (1) consensual strategy to compromise sustainability requirements (2) concealment strategy. In addition, this paper identifies multiple institutional types of conflicting logics: instrumental logic, legitimacy logic complexity and gaps in normative logic, which interplay amongst sub-suppliers whereby permit to decouple the implementation of supply management practices.Research limitations/implicationsWhile the current paper provides an early contribution from the perspectives of second-tier and third-tier suppliers, future research could be extended to include further upstream sub-suppliers and downstream tiers including the end consumers.Practical implicationsIt is important for brand-owning retailers and first-tier suppliers to predict sub-suppliers' decoupling behaviour and conflicts for supply management practices implementation since they may present potential vulnerability for buyers and lead suppliers.Originality/valueThis study extends the application of institutional theory and contributes to the literature on extended suppliers' supply management practices in a developing country context, which is an under-researched area.

Abstract Nephelium topengii is an evergreen tree of the Sapindaceae family, which can be used as timber. Here, we report and characterize the complete plastome of N. topengii. The complete plastome is 162,944 bp in length and contains the typical structure and gene content of angiosperm plastome, including two inverted repeat (IR) regions of 30,092 bp, a large single-copy (LSC) region of 85,909 bp and a small single-copy (SSC) region of 16,851bp. The plastome contains 130 genes, consisting of 80 unique protein-coding genes, 30 unique tRNA gene, 4 unique rRNA genes (5S rRNA, 4.5S rRNA, 23S rRNA and 16S rRNA). The overall A/T content in the plastome of N. topengii is 62.30%. The complete plastome sequence of N. topengii will provide a useful resource for the conservation genetics of this species as well as for phylogenetic studies in Sapindaceae.
X‐Ray Compton Scattering Study of Liquid Sodium at Elevated Temperatures

X‐ray Compton scattering measurements using synchrotron radiation are carried out for liquid sodium (Na) from 473 K up to 1273 K. Utilizing the liquid state allows us to realize a continuous density reduction by controlling temperature and pressure. Valence Compton profiles (CPs) clearly exhibit thermodynamic state dependence as the temperature increases. Experimental CPs, CP differences, and electron kinetic energy are compared with those of the electron gas model. Combined with the analysis using the Fourier‐transformed CPs, the observed behaviors can be reasonably explained by the reduction in the electron density with volume expansion of the liquid.
Sustainable use of industrial-waste as fine-aggregate of Foam Concrete

The benefits of using industrial waste as a replacement for natural sand and cement in light-weight concrete are also discussed. The paper presents the use of fly ash and blast furnace slag to replace 100% sand in foam concrete with a wet density of 1700 kg/m3 and 900 kg/m3 as well as their mechanical properties. The absolute volume method was used to calculate the ratio of foam concrete mixture. Besides, the foam concrete mechanical properties are determined according to the Russian standard GOST 10180-2012. Research results indicate that at the age of 28 days with Series I, the value of compressive strength obtained from 13.91MPa to 42.35 MPa, flexural strength from 0.53 MPa to 1.06 MPa and water absorption between 0.92% and 5.78% with Series II these values from 1.69 MPa to 8.22 MPa for compressive strength, from 3.25 MPa to 6.72 MPa for flexural strength and the result for water absorption is in the range of 12.35% and 22.16%. Besides that, research results also indicate that the correlation between dry density and compressive strength has a positive linear relationship. The results of this study have proved that foam concrete uses fly ash and blast furnace slag can replace traditional concrete in construction as well as replacing clay bricks will not only improve concrete strength but also reduce costs as well as protect the environment.
Who is fishing on what stock: population-of-origin of individual cod (Gadus morhua) in commercial and recreational fisheries

Atlantic cod (Gadus morhua) in Skagerrak are structured into distinct ecotypes or stock components that have been severely depleted over the past decades. To improve our understanding of how local commercial and recreational fisheries influence cod stocks, we investigated whether these user groups target different stock components of cod. Cod were sampled from the recreational rod and line fishery and from commercial shrimp trawlers catching cod as by-catch. Based on a large set of single nucleotide polymorphisms (SNPs), we defined a subset of 27 semi-diagnostic SNPs designed to discriminate between two cod stock components: “inner fjord” cod and “North Sea” cod, designated by their dominant habitat preferences. Genetic assignments of fishery-caught cod indicated that 4% of individuals caught by shrimp trawlers belonged to the inner fjord cod component and 96% to the North Sea, whereas among cod caught by recreational fishers, the estimated percentages were 11.8 and 88.2%, respectively. Our findings confirm the existence of two sympatric cod stock components in coastal Skagerrak, indicating that existing management units are biologically inappropriate and should be reconsidered. Furthermore, more attention should be given to recreational angling to reduce fishing mortality on the depleted inner fjord cod component.
L’analyse des relatives de l’anglais en grammaire générative : perspective historique

Le present article est un rapide survol de la longue histoire des analyses des relatives depuis les debuts de la grammaire generative jusqu’au XXIe siecle. Il montre comment on est passe des phrases-noyau et des transformations a des approches qui doivent leur sophistication au modele X’ d’une part et a la theorie du DP d’autre part. Il montre egalement comment, qu’il s’agisse des Principes et Parametres ou de la theorie de l’antisymetrie, les derniers developpements de la GB aboutissent finalement a reintroduire l’idee, centrale dans les annees 60, que la relative a etroitement partie liee avec le determinant du N relativise.
DNA extraction methods for molecular detection of Eimeria spp. in cattle and sheep

ABSTRACT: Molecular detection of Eimeria species in fecal samples can be useful for experimental and diagnostic purposes. However, the parasite quantity presence in feces and the oocyst wall are an obstacle in DNA extraction protocols. Therefore, adequate sampling and effective disruption of the oocysts are essential to improve the accuracy of DNA detection by PCR. The aims of this study were to evaluate the suitability of six protocols for DNA extraction from Eimeria spp. present in bovine and sheep. Twenty pools of fecal samples from cattle (10 pools) and sheep (10 pools) were distributed to six DNA extraction protocols: commercial kit, commercial kit with modification, DNAzol, cetyl-trimethyl ammonium bromide (CTAB), glass beads and commercial kit for fecal samples. Fecal samples were submitted to DNA extraction and PCR. Among the protocols tested, CTAB was determined to be most suitable for DNA extraction from oocysts (90% of DNA detection by PCR); DNAzol and CTAB resulted in higher DNA detection from bovine samples (80%). CTAB and commercial kit with modification improved PCR detection of Eimeria spp. in sheep samples, with positive amplification of DNA in all tested samples.
Black Friday rituals, customer perceived value and loyalty among young adult customers in South Africa: A Stimulus-Organism-Response perspective

Abstract The study explores the nexus of relationship between Black Friday rituals, customer value and customer loyalty among young adult customers in South Africa. A descriptive research design was followed and data were collected from 400 young adult customers aged 18–35 in the Gauteng province of South Africa through self-administered questionnaires. Furthermore, the measurement and structural models were assessed using Amos 23.0. Relational capital and social influence significantly and positively influence customer-perceived value, while customer-perceived value significantly and positively influences the customer loyalty of young adult customers towards Black Friday rituals. The testing of the proposed model validates the relationships that are hypothesised between the independent variables (cognitive capital, relational capital, social identification, social influence, social convenience), customer-perceived value and customer loyalty of young adult customers. The findings assist retailers in understanding how relational capital and social influence can strengthen the perceived value perception of young adult customers towards Black Friday rituals, leading to customer loyalty. The study focused on the customer loyalty of young adult customers of Black Friday rituals and determined the interrelationships of the extent to which they encounter customer-perceived value and related constructs. However, a limited number of studies have examined how the Stimulus-Organism-Response theory is applied to customer-perceived value and customer loyalty from an emerging African market perspective.

Guillain‐Barré syndrome (GBS) and Miller Fisher variant (MFv) cases spiked threefold in Los Angeles, with a high proportion of MFv cases. MFv is underdiagnosed when accompanying neurological symptoms are mild. This report emphasizes the seasonality of GBS and its relation to ganglioside antibodies.
Outdoor Particulate Matter Correlation Analysis and Prediction Based Deep Learning in the Korea

Particulate matter (PM) has become a problem worldwide, with many deleterious health effects such as worsened asthma, affected lungs, and various toxin-induced cancers. The International Agency for Research on Cancer (IARC) under the World Health Organization (WHO) has designated PM as a group 1 carcinogen. Although Korea Environment Corporation forecasts the status of outdoor PM four times a day, whichever is higher among PM10 and PM2.5. Korea Environment Corporation forecasts for the stages of PM. It remains difficult to predict the value of PM when going out. We correlate air quality and solar terms, address format, and weather data, and PM in the Korea. We analyzed the correlation between address format, air quality data, and weather data, and PM. We evaluated performance according to the sequence length and batch size and found the best outcome with a sequence length of 7 days, and a batch size of 96. We performed PM prediction using the Long Short-Term Recurrent Unit (LSTM), the Convolutional Neural Network (CNN), and the Gated Recurrent Unit (GRU) models. The CNN model suffered the limitation of only predicting from the training data, not from the test data. The LSTM and GRU models generated similar prediction results. We confirmed that the LSTM model has higher accuracy than the other two models.
Wave propagation analysis of a rectangular sandwich composite plate with tunable magneto-rheological fluid core

This study presents an investigation of the wave propagation of a rectangular sandwich composite plate with tunable magneto-rheological fluid core. The constituent parts of this rectangular sandwich composite plate are the base layer, magneto-rheological fluid core, and limiter layer. Magneto-rheological fluid core is embedded within the base and limiter layers. Also, the upper and lower layers are made of elastic materials. For obtaining the governing equations of motion, Hamilton’s principle and classical plate theory are used. After that, applying an analytical solution, the wave frequency and phase velocity of the propagated waves can be gained by solving eigenvalue problem. By investigating the effect of the magnetic field, the results emphasize that the magnetic field intensity is the most important factor for changing the value of the wave frequency and phase velocity. Besides, results show by enhancing the core-to-top layer thickness ratio, the wave frequencies reduce because magneto-rheological fluid core is softer in comparison to elastic layers. Therefore, magneto-rheological fluid layer operates similar to a damper. At the end, the influence of the thickness of magneto-rheological fluid core on the phase velocity is also discussed.
