Use of Nanoparticle Enhanced Phase Change Material for Cooling of Surface Acoustic Wave Sensor

The use of resonators, filters, interdigital transducers (IDT) and stable sources in electronic industry is widespread today. One of the most used filters are the surface acoustic wave (SAW) type, which is mostly based on Rayleigh waves propagation on the surface. On the other hand, the use of Phase change materials (PCMs) is considered as a heat sink method in the field of thermal cooling of electronic circuits. Recent development in heat transfer is obtained by nanoparticle-enhanced PCM (NEPCM), which is a result of combining nanoparticles with PCMs. Increase of thermal conductivity of NEPCM in comparison with common PCM enhances the heat transfer rate. The aim of the current study is thermal management of SAW for the application of high frequency heating by phase change material. Melting of NEPCMs inside a rectangular cavity next to the SAW cell is used for the cooling purpose. Free convection heat transfer of a NEPCMs in an square cavity is modeled throughout the mass and momentum. Energy governing equations are solved by using the finite element method. Electrohydrodynamic (EHD) forces exist in natural convection heat transfer within the fluid part of the enclosure. The results also show that the NEPCM causes heat transfer improvement up to 10%.
Management of the Sensitized Cardiac Transplantation Recipient

Preoperative sensitization of the cardiac transplant recipient, defined as the presence of anti-Human Leukocyte Antigen (HLA) antibodies before transplant, represents a significant management challenge for physicians. Sensitization prolongs the pre-transplant wait time and is associated with postoperative transplant complications and death. It is critical that sensitized heart transplant candidates be identified and optimized before surgery. In this review, we describe the risk for sensitization, discuss the means through which sensitization may be diagnosed, and highlight some of the new therapeutic options for managing the sensitized cardiac transplant patients.
Social support and recovery from mental health problems: a scoping review

ABSTRACT Several systematic reviews have suggested the linkages between social support and mental health or the use of mental health services in general. There is a need to develop the knowledge on different associations between social support, social work and mental health recovery, and the various features of social support. Inequality in health is a rising problem. Broader integration of social support-orientation in services and policy can play an important role in reducing health inequalities and enhance recovery. In this article we aim to scope existing literature regarding (a) the associations between social support, mental health and recovery, and (b) describe features of community mental health services that incorporate social support. Further, we discuss facilitators and barriers for social work and social support. Advanced searches were conducted in five relevant databases: Social Science Premium Collection, CINAHL, SweMed+, Idunn, and PsychInfo Ovid, and we did a qualitative synthesis of the included papers. Twenty-nine papers met the inclusion criteria in this scope and are organized into two major themes: a) Associations between mental health and social support, and b) Key features of social support-oriented community mental health services.
Effect of organic, inorganic and biofertilizer on growth, yield and quality attribute on brinjal crop

A field study was conducted during the Kharif season of 2019-20 at Department of Horticulture, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj to study about the “Effect of organic, inorganic and bio-fertilizer on growth, yield and quality attributing characters of Brinjal ( Solanum melongena L.) cv. Pusa Kranti”. The experiment was laid out in a randomized block design with 10 treatments replicated thrice. Bio-fertilizers and manures viz., PSB (Phosphorous solubilizing bacteria), VAM (Vesicular Arbuscular Mycorrhiza), FYM and Vermi compost, were used alone and in different combinations with chemical fertilizers. All the bio-fertilizers are applied as soil application method in which 200g of each bio-fertilizers are mixed in soil. Among all the treatments, it is noticed that the growth, yield and quality attributing parameters like plant height, number of primary branches, number of secondary branches, fruit length, fruit width, total number of fruits/ plot and fruit yield were found maximum with the application of 75% FYM + PSB + VAM+ 25% NPK and the minimum being recorded in control in which no bio-fertilizers and chemical fertilizers were used. So based on the results it could be concluded that the application of VAM and PSB in combination with 75% N, P & K favourably influenced the growth, yield and yield attributing characters in brinjal cv. Pusa Kranti.
The Interplay Between Sentiment and MAX: Evidence from an Emerging Market

Investors with lottery preferences are known to concentrate on stocks with rare but extreme past returns. We investigate the extent to which lottery preference, measured by the MAX variable, varies with the market-wide irrational sentiment. We find that the high-MAX stocks have higher overpricing in a high-sentiment market and earn a lower alpha, compared to the low-sentiment market. Accordingly, the poor returns earned by a long-short portfolio of stocks with extreme MAX values are primarily due to the overvaluation of the high MAX-portfolio during the high sentiment phase. The higher stock volatility in India also magnifies the lottery preference of investors. JEL Classification: G4, G12, G41, G11
Why Lenin failed to implement Marx’s concept of socialism: an accounting history of the Russian revolution, c.1917–1924

ABSTRACT To orthodox Marxists socialism means central planning. Capitalist accounting is, however, integral to Marx’s socialism that envisages universal worker co-operatives, initially accountable to workers and society for value, but with the interim aim of increasing the ‘productive forces’ to make every labour hour ‘directly’ of equal social value. This study tests the implication that implementing Marx’s socialism requires understanding capitalist accounting by examining its role in the Russian revolution. Lenin failed, it argues, because he did not understand capitalist accounting, Marx’s explanation of it, or his interim aim. Lenin stressed accounting’s centrality, but equated it with budgeting, and confused Marx’s interim aim with Day 1, which led him to support ‘centralisation’ and ‘workers’ control’. Lenin admitted a ‘mistake’ in 1921 when he had understood, apparently intuitively, the necessity of accountability for profit, which underlay his ‘New Economic Policy’, the reintroduction of double-entry bookkeeping in 1922, and his 1923 vision of socialism built from co-operatives. Lenin failed to overcome his comrades’ orthodoxy, and after his death in 1924 Stalin dropped his ideas, which the study hypothesises had important implications for twentieth-century geopolitical history.
Love cannot buy you money: Resource exchange on reward‐based crowdfunding platforms

Reward‐based crowdfunding platforms – in which campaigns exchange rewards for financial backing to develop a product or service – are one of the fastest‐growing segments of the crowdfunding industry. We use an extension of social exchange theory (SET) called the resource theory of social exchange (RTSE) to examine resource exchanges through rewards on Kickstarter. A resource exchange occurs when a project backer and project creator exchange money (ie, financial backing) for a reward (eg, a thank you or a t‐shirt). A project creator can develop a reward portfolio that contains various types of resources, which in the RTSE are categorised as love, status, information, money, goods and services. Our study provides a comprehensive examination of resource exchange on a major reward‐based crowd funding platform, answering the call to investigate the effects of a key element of such platforms – rewards. We find that the types of resources project creators include in the reward portfolios they offer should be carefully considered. Specifically, our results indicate it is more beneficial to offer rewards that contain universal and concrete resources (eg, goods, services) than resources that are particularistic and symbolic (eg, love, status). However, the positive effect of offering universal and concrete resources as rewards is diminished as the fundraising goal is increased, which suggests that the optimal design of the reward portfolio is contingent on other characteristics of the campaign. Moreover, our findings reveal that while it is advantageous to offer more rewards, it is disadvantageous to offer too many different types of resources across those rewards. Overall, our study adds depth to the understanding of resource exchange in reward‐based crowdfunding and provides practical insight into how to design reward portfolios.
Determination of cell fate in skeletal muscle following BMP gene transfer by in vivo electroporation

We previously developed a novel method for gene transfer, which combined a non-viral gene expression vector with transcutaneous in vivo electroporation. We applied this method to transfer the bone morphogenetic protein (BMP) gene and induce ectopic bone formation in rat skeletal muscles. At present, it remains unclear which types of cells can differentiate into osteogenic cells after BMP gene transfer by in vivo electroporation. Two types of stem cells in skeletal muscle can differentiate into osteogenic cells: muscle-derived stem cells, and bone marrow-derived stem cells in the blood. In the present study, we transferred the BMP gene into rat skeletal muscles. We then stained tissues for several muscle-derived stem cell markers (e.g., Pax7, M-cadherin), muscle regenerationrelated markers (e.g., Myod1, myogenin), and an inflammatory cell marker (CD68) to follow cell differentiation over time. Our results indicate that, in the absence of BMP, the cell population undergoes muscle regeneration, whereas in its presence, it can differentiate into osteogenic cells. Commitment towards either muscle regeneration or induction of ectopic bone formation appears to occur five to seven days after BMP gene transfer.
A new hydrobiid species (Caenogastropoda, Truncatelloidea) from insular Greece

Daphniola dione sp. nov., a valvatiform hydrobiid gastropod from Western Greece, is described based on conchological, anatomical and molecular data. D. dione is distinguished from the other species of the Greek endemic genus Daphniola by a unique combination of shell and soft body character states and by a 7–13% COI sequence divergence when compared to congeneric species. The only population of D. dione inhabits a cave spring on Lefkada Island, Ionian Sea.
Zero-sum differential games-based fast adaptive robust optimal sliding mode control design for uncertain missile autopilot with constrained input

This paper designs a novel adaptive robust optimal sliding mode control (SMC) strategy for constrained input missile system with uncertain input and unknown disturbance. First, a smooth function is employed to map the constrained input. Based on SMC theory, a fast adaptive SMC scheme is designed to reduce the effects of unknown input and approximate error which has two advantages. One is that the proposed scheme is independent of the uncertain information. The other is that the proposed scheme forces the states to converge with exponential rate as they are far away from the sliding mode surface, and the states move with linear rate when they are closed to the sliding mode surface. Then, a zero-sum differential games strategy-based adaptive dynamic programming (ADP) technique is employed to obtain the optimal performance of sliding mode dynamics system. The loop-system and estimation weight error can be proved stable by utilising Lyapunov theory. Finally, the missile autopilot system is used to indicate the effectiveness of the designed approach.
Coplanar Strip Line-Fed Series Dipole Array Antenna for High-Gain Realization

In this communication, we present a coplanar strip (CPS) line-fed series dipole array antenna for high-gain realization. Printed dipoles of the same size are connected using the CPS line, and impedance matching is achieved with an integrated balun. The gain of the designed array antenna is increased by approximately 2.6 dB as the number of dipoles is doubled. Unlike the conventional endfire array, which has no gain increment beyond a certain number of radiation elements, the gain of the proposed array antenna continuously increases in proportion to the number of dipoles. A CPS line-fed series array antenna with 32 dipole elements was fabricated and evaluated. The measured gain of the 32 dipole array antenna at a center frequency of 15 GHz was 17.4 dBi, the measured −10 dB impedance bandwidth was 9.1–21.6 GHz, and the measured 3 dB gain bandwidth was 13.4–17.4 GHz. The dimensions of the designed dipole array antenna are <inline-formula> <tex-math notation="LaTeX">$0.7\,\,\lambda _{o} \times 13.2\,\,\lambda _{o} \times 0.0063\,\,\lambda _{o}$ </tex-math></inline-formula>, where <inline-formula> <tex-math notation="LaTeX">$\lambda _{o}$ </tex-math></inline-formula> is the free space wavelength at the center frequency.
The p62/Keap1/Nrf2 axis in the control of C-2 induced human gastric cancer cell death switching between autophagy and apoptosis

Background Compound C-2 is a derivative of natural product Jaspine B and possesses anti-cancer activity against bladder cancer cells. However, little is known about its anti-cancer activity against gastric cancer. In this research, mechanism underlying anti-cancer effect of C-2 in gastric cancer cells was well investigated. Methods Anti-cancer activities of C-2 were determined by MTT, western blotting and flow cytometry. A serial of specific inhibitors, immunoprecipitation, siRNA and immunofluorescence were utilized to explore signaling pathways affected by C-2. Results C-2 induces apoptosis in gastric cancer cells through the internal mitochondrial pathway, and triggers autophagy in gastric cancer cells through JNK/ERK pathway. Phosphorylated JNK/ERK further activates Beclin1 via disturbing Beclin-1/Bcl-xL or Beclin-1/Bcl-2 complexes, leading to autophagy and up-regulated p62. Next, p62 competitively binds keap1 to release Nrf2, thus promoting translocation of Nrf2 from cytoplasm to nucleus and triggering expression of Nrf2 target genes. Pharmacological inhibition or knockdown of key proteins in autophagy attenuates C-2 induced cell apoptosis, indicating that autophagy antagonizes cell apoptosis induced by C-2. Conclusion C-2 possesses anti-tumor activity against gastric cancer cells, while C-2 triggered-autophagy antagonizes cell arrest and apoptosis induced by C-2 by upregulating Nrf2 in nucleus.
What Makes Government Work Great: The Characteristics of Positive Public Service

Optimal work experiences in the public sector do not receive the attention they deserve. And, though positive psychology research has shown that flourishing in the workplace is connected to healthier and more fulfilled employees as well as improved organizational performance, the public sector has largely taken a backseat as a subject of study in this field. This article addresses this shortcoming by conducting in-depth interviews of current and former public servants to identify the most prevalent features of their best work experiences and their connection to the components of prominent well-being theories. Five characteristics of positive public service emerged: challenge, efficacy, camaraderie, empowerment, and service. Several well-being components were connected to these characteristics as were other features such as hardship, novelty, leadership, and helping others. These findings provide a stronger theoretical basis to suggest that more can be—and should be—expected of government work.
Teacher Work Productivity in Senior High School

Work productivity of teachers shall determine the advancement of education quality as their direct encounter with students to equip them with skill and competencies. This study was conducted to see the direct effect of job satisfaction and absenteeism on high school teachers’ work productivity in Bekasi region. Survey method with path analysis approach was applied. Questionnaire as the study instrument was distributed to 198 teachers who were chosen based on simple random sampling technique. The study revealed that, first, job satisfaction has a positive direct effect on teacher work productivity. The correlation coefficient value is 0.431, while the path coefficient value is 0.228. It infers that when job satisfaction is fulfilled, work productivity shall increase as well. Second, absenteeism shows a negative direct influence on work productivity. The correlation coefficient value is - 0.427 and the path coefficient value is -0.250. This further implies that productivity and progress of organization are impeded by the absence of teacher. This leads to a notion that teacher lower level of absenteeism will increase their productivity. Third, job satisfaction gives a negative direct impact on absenteeism. The correlation coefficient value is -0.341 and the path coefficient value is -0.207. The result leads to a conclusion that once teachers feel contented with their work, they will rarely perform absenteeism
Residual oxygen groups in nitrogen-doped graphene to enhance the capacitive performance

Nitrogen-doped graphene (NG) was obtained from a facile and eco-friendly hydrothermal reaction and used as electrode materials for supercapacitors. The textural and chemical properties could be easily tuned by adjusting the basicity of the reaction environment. As the basic reaction conditions became stronger, the sheets of NG tended to stack together, the content of residual oxygen groups increased, but the nitrogen content decreased, which affected the electrochemical performance. The NG synthesized under a weak basic environment shows great pseudocapacitance and the largest electrochemical performance in a 6 mol L−1 KOH aqueous electrolyte when measured in a three-electrode system, which can be attributed to its randomly distributed and loosely stacked structure and high amount of residual oxygen atoms (12.8 at%). Furthermore, it presented excellent cycling stability with a capacitance retention ratio of 92.86% at the current densities of 5 A g−1 after 10 000 charge–discharge cycles in two-electrode configuration, which kept stable after 5000 cycles. These results implied that the NG sheets obtained by this simple eco-friendly approach are suitable for high performance supercapacitor applications.
Cost-benefit analyses of employment services for individuals with intellectual and developmental disabilities: A scoping review

BACKGROUND: Understanding the cost-benefit of vocational rehabilitation services is critical to improve competitive integrated employment outcomes for individuals with intellectual and developmental disabilities (IDD). OBJECTIVE: The purpose of this scoping review was to analyze and synthesize micro and macroeconomic analyses of various types of vocational services which promote the employment outcomes of individuals with IDD. METHODS: This scoping review searched peer-reviewed and grey literature sources published between 2000 and 2020, examining both micro and macroeconomic analyses. RESULTS: A total of 26 studies met inclusion criteria. The majority of studies reported positive effects for the cost-benefit of integrated service approaches such as supported and customized employment. Conversely, our findings show no cost-benefit for sheltered workshops, and in some cases, negative effects. CONCLUSION: Limitations to the included studies as well as implications and recommendations for practice, policy, and future research are discussed.
Stable isotope and chemical stratigraphy of the Eocene Tambaba Formation: correlations with the Paleocene–Eocene Thermal Maximum event

Abstract The Paraíba Basin has a well-defined carbonate depositional sequence from the Upper Cretaceous (Campanian) to the Eocene. The carbonate sequence consists of the Itamaracá, Gramame, Maria Farinha and Tambaba formations, which mainly contain calcareous sandstones and carbonates with siliciclastics, limestone–marl alternations, limestones and marls, and limestones, respectively. The Tambaba Formation is composed of reef limestones, ranging from fossil- and ichnofossil-rich calcilutite to calcarenite. We investigated rocks of this unit located in a representative geological section at the Tambaba Beach, northeastern Brazil, in order to elucidate the environmental responses recorded in geochemical proxies (C and O isotopic composition, and distribution of major and trace elements). The δ13C and δ18O values ranged from 1.0 to 2.7‰ VPDB and from −1.3 to 1.1‰ VPDB, respectively. The interpretation of this response suggests environmental changes, such as an increase or decrease in bioproductivity of the organisms that make up these reef limestones. These changes are also recorded in the behaviour of the major and trace elements – for example, the relationship between SiO2, Al2O3, MgO and CaO, characterizing two different cycles during the deposition of these limestones: the first one characterized by a predominantly carbonate deposition, and the second one presenting a pulse of siliciclastic content. In addition, palaeotemperature values (9–15°C, from δ18O data) obtained, together with chemostratigraphic profiles of previous studies (e.g. δ13C, CaO, MgO, SiO2, Al2O3), indicate that the reef limestones of the Tambaba Formation were probably deposited about 5 myr after the Paleocene–Eocene Thermal Maximum event.
Energetic Estimates and Asymptotics for Electro‐Reaction‐Diffusion Systems

In this paper we deal with equations modelling the transport of electrically charged species in heterostructures by diffusion, drift and reaction processes. We show that for such models the free energy decays monotonously and exponentially to its equilibrium value. For this purpose we prove an estimate of the free energy from above by the corresponding dissipation rate. Exactly the same results are obtained for the fully implicit discrete‐time scheme.
A review of measuring ecosystem resilience to disturbance

Resilience is the central concept for understanding how an ecosystem responds to a strong perturbation, and is related to other concepts used to analyze system properties in the face of change such as resistance, recovery, sustainability, vulnerability, stability, adaptive capacity, regime shift, and tipping point. It is extremely challenging to formulate resilience thinking into practice. The current state-of-art approaches of assessing ecosystem resilience may be useful for policy makers and ecosystem resource managers to minimize climatological or natural disaster related impacts. Here, we review the methods of assessing resilience and classify and limit them to three cases: (a) forest resilience based mainly on remote sensing and tree-ring data; (b) soil microbial community resilience based on laboratory and field studies; and (c) hydrological resilience of terrestrial biomes based on the Budyko framework and climate data.
Quiescent regions below the X-point in ASDEX upgrade

Probe measurements of plasma fluctuations in the divertor region of ASDEX Upgrade reveal the existence of two quiescent regions close to the separatrix: one on the low field side scrape-off layer and one on the high field side of the private flux region. The X-point manipulator at ASDEX Upgrade provides the unique possibility of obtaining continuous measurements of the ion-saturation current from the low field side scrape-off layer through the private flux region and into the high field side scrape-off layer.
