Vertical Blade Fiberglass Composite for Wind Turbine Power Plant Application

Wind is a renewable energy that is used for electrical energy in several countries. Indonesia is one of the countries that utilizes wind energy for electrical energy. The potential for wind in Indonesia is located in coastal areas. To apply the potential for wind in urban areas is very difficult because the wind speed is very low. From this problem, this paper presents a windmill using fiberglass. Fiberglass is an alloy or mixture as a composite material which has the characteristics of light weight, easy shape, and low cost. The aim is to analyze the mechanical properties of fiberglass composite materials in the application of blades or vanes in savionus windmills. This study uses the hand lay-up method and the mechanical testing method for tensile strength and impact which aims to determine the material properties of the blade of the savonius windmill. Based on the tensile test, the average tensile strength of random fiberglass composite and 200gr 2-layer woven roving was 49.52 MPa with an average modulus of elasticity of 21.88 Gpa. For the Charphy impact test, the average impact strength is 0.035 joules / mm2 with the energy absorbed is 0.7046 joules.
Cooperation Networks and Embeddedness—The Case of the Portuguese Footwear Sector

The purpose of this paper is to explore the role of embeddedness and cooperation networks in the business internationalization process. To achieve the abovementioned purpose, a qualitative methodology was carefully chosen, through which semi-structured interviews were conducted with ten entrepreneurs of the footwear sector in Portugal, as well as with a head of the national footwear business association. In order to process the data obtained by conducting the interviews, content analysis and data coding through the NVivo software were performed. The results suggest that internationalization is essential for companies in the Portuguese footwear sector. In addition to internationalization helping companies to increase their turnover, it allows companies to grow in a more sustainable way. On the other hand, research also allows us to deduce that networks play an important role in the development of the organizations in question, as they facilitate access to various resources indispensable to this growth. Concerning embeddedness, this aspect presents itself as a facet to which special attention should be paid, considering the pre-eminence that respondents attribute to all variables that help to structure this dimension. The conclusions of this study have theoretical and practical implications, which provide empirical evidence of how the internationalization process can influence the activity of Portuguese companies in the footwear sector. In addition, the results contribute to the evolution of existing knowledge about how embeddedness and cooperation networks facilitate the internationalization process.
Field evaporation of metal atoms onto insulator/conducting substrate using atomic force microscope

The feasibility of field-evaporating metal atoms onto an insulator/conducting substrate has been investigated. Theoretical and experimental studies clarify that field evaporation is possible in an atomic force microscope (AFM) metal probe/vacuum/thin insulator/conductor configuration. Theoretically, field evaporation is easily achieved on thin SiO2 insulators of less than 100 A, though image potential and electric field weaken in the presence of an insulating layer. Experiments confirm that ultrasmall gold dots can be formed on a natural SiO2/Si substrate with a threshold voltage of around 10 V. Small dots of 15 nm diameter can be obtained.
Effect of electrostatic boundary conditions and system size on the interfacial properties of water and aqueous solutions

The consequences of the choice of electrostatic boundary conditions on the interfacial properties of water and on the free energy of ion adsorption from aqueous solution have been investigated. The Ewald summation method for lattices, which are periodic in two dimensions, is considered to be the most adequate method in slabs of finite thickness in one dimension. In agreement with the physics of the problem a field-free region in the bulk phases is observed. The use of spherical truncation methods like the shifted-force method leads to unphysical results. The electrostatic potential depends on the size of the system. Ewald summation methods for three-dimensional lattices lead to results in qualitative agreement with the corresponding two-dimensional lattice sum. The computed value of the electrostatic potential depends on an additional parameter, namely the lattice constant c in the direction perpendicular to the interface. The results for Ewald summation in three dimensions converge to the results for Ewa.
PREPARATION AND EVALUATION OF AVIAN INFLUENZA (H9) AND NEWCASTLE DISEASE (THERMOSTABLE I-2 STRAIN) BIVALENT VACCINE FOR COMMERCIAL POULTRY

The goal of current research was production of bivalent adjuvant based inactivated I-2 strain of Newcastle Disease (ND) and Avian Influenza (AI) vaccine and to compare efficacy with commercially available bivalent inactivated vaccine. Experiment was carried out on one-day-old broiler chicks by dividing them into 3 groups A, B & C. Vaccine was injected on 7, 14, 21 and 28 day. Blood samples were collected on 7, 14, 21, 28 and 35 day. Results of Hemagglutination Inhibition (HI) test presented the geometric mean titers of group A and B were <1:4, 1:18.8, 1:115.2, 1:358.4, 1:128 & <1:4, 1:8.4, 1:36.8, 1:56, 1:22.4 respectively for AI. Similarly the geometric mean titers of group A and B were <1:4, 1:19.6, 1:89.6, 1:320, 1:115.2 & <1:4, 1:9.2, 1:25.6, 1:36.8, 1:22.4, respectively for ND. However, control group showed <1:4 geometric mean titer. The challenge was given on 28th day and birds were monitored for next 7 days for clinical signs. The chicks of group A showed no clinical signs of diseases (AI, ND). However, in group B 60% morbidity and 90% mortality was recorded on 4th and 6th day of post challenge, respectively. While 100% mortality was recorded in control group.
Template-Synthesized Polyacetylene Fibrils Show Enhanced Supermolecular Order

Abstract : We have recently described a template method for synthesizing nanoscopic conductive polymer fibrils. In this method, the pores in a nanoporous host membrane are used as templates for the nascent conductive polymer. We have shown that such template-synthesized fibrils show significantly higher conductivities than bulk films of the analogous polymer. We suggested that this enhanced conductivity results from preferential orientation of the polymer chain parallel to the fibril axis. This paper provides the first experimental proof for such enhanced supermolecular order in template-synthesized conductive polymer fibrils. We describe (for the first time) the template synthesis of nanoscopic polyacetylene fibrils. We demonstrate (using a polarized infrared absorption experiment) that the polymer chains in these fibrils are preferentially oriented parallel to the fibril axis. (js)
Selective oil agglomeration of lignite

In this study, desulfurization and deashing of Adiyaman-Golbasi lignite by the agglomeration method were studied. For this purpose, three groups of agglomeration experiments were made. The effects of solid concentration, bridging liquid type and dosage, pH, and screen size on the agglomeration after desliming were investigated in the first group of experiments. The effects of lake water and sea water (the Mediterranean Sea water, the Aegean Sea water, and the Black Sea water) on the agglomeration were investigated in the second group of experiments. The effects of different salts (NaCl, MgCl2, and FeCl3) on the agglomeration were investigated in the third group of experiments. Agglomeration results showed that the usage of sea waters and soda lake water in the agglomeration medium had a positive effect on the reduction of total sulfur content of agglomerates. In addition, the usage of NaCl, MgCl2, and FeCl3 in the agglomeration medium had a positive effect on the ash content reduction of the agglomerates.
Opinion-Based Co-Occurrence Network for Identifying the Most Influential Product Features

Nowadays, social networking sites such as Facebook, Twitter, LinkedIn, YouTube, and other e-commerce websites produce a large number of text reviews. These text reviews mostly describe the product features and their opinions, which are the most important to the product developers, launchers, or buyers for business development and decision-making processes. Therefore, we present an opinion-based co-occurrence network for product reviews. The main aim of this research is to identify the popularity of product features or popular terms, the number of connections of a term, the strong relationship between terms, grouping the product terms, and the sentiment polarity links between terms in both positive sentiment and negative sentiment. Also, we employed the Harel-Koren fast multi-scale layout algorithm and CNM (Clauset-Newman-Moore) algorithm for visualizing and grouping the network. We then measured the overall graph metrics and vertex metrics to characterize the network. Additionally, the experimental result shows the ranked product features and their social strength between product features and sentiments.
Edge-iodine/sulfonic acid-functionalized graphene nanoplatelets as efficient electrocatalysts for oxygen reduction reaction

We report the synthesis of edge-iodine/sulfonic acid-functionalized, graphene nanoplatelets (ISGnPs) via two-step sequential ball-milling of graphite, and their use as electrocatalysts for oxygen reduction reaction (ORR) in fuel cells. Graphite is ball-milled in the presence of iodine to produce the edge-iodine functionalized GnP (IGnP) in the first step and the IGnP is subsequently ball-milled with sulfur trioxide to yield the ISGnP. The resultant ISGnP is highly dispersible in various polar solvents, allowing the fabrication of electrodes for ORR using solution processing. The capacitance and cycle stability of the ISGnP in an alkaline medium are superior to commercial Pt/C and its kinetic electron transfer number (n) is comparable to Pt/C.
Directed-Mutagenesis and Deletion Generated through an Improved Overlapping-Extension PCR Based Procedure

Generating either single or multiple point mutations and producing deletions and insertions into targetDNA sequences are critical and widely used experimental procedures in molecular biological studies. This articlepresents a modified mutagenesis protocol based on an overlapping-extension PCR amplification method. Theprocedure benefits from the design of mutagenic primers to generate overlapping megaprimers without the needfor intermediate purification to remove unused primers. Unused primers are diluted out during the successiveamplification-extension reactions. A key success to this modified method is the use of two flanking primers afterthe overlapping extension reaction. The use of Pfu DNA polymerase increases, compared with Taq DNApolymerase, amplification accuracy. The proposed procedure represents a simple and efficient method thatintroduces many types of mutations into specific target DNA fragments and creates either hybrid DNA fragmentsor internal nucleotide deletions. Key Words: Directed-mutagenesis; Megaprimers; Overlapping primers; Pfu DNA polymerase
A relaxed generalized Newton iteration method for generalized absolute value equations

To avoid singular generalized Jacobian matrix and further accelerate the convergence of the generalized Newton (GN) iteration method for solving generalized absolute value equations Ax - B|x| = b, in this paper we propose a new relaxed generalized Newton (RGN) iteration method by introducing a relaxation iteration parameter. The new RGN iteration method involves the well-known GN iteration method and the Picard iteration method as special cases. Theoretical analyses show that the RGN iteration method is well defined and globally linearly convergent under suitable conditions. In addition, a specific sufficient condition is studied when the coefficient matrix A is symmetric positive definite. Finally, two numerical experiments arising from the linear complementarity problems are used to illustrate the effectiveness of the new RGN iteration method.
Protection strategies for biocatalytic proteins under plasma treatment

In plasma-driven biocatalysis, enzymes are employed to carry out reactions using species generated by non-thermal plasmas as the precursors. We have previously demonstrated that this is feasible in principle, but that the approach suffers from the short lifetime of the biocatalyst under operating conditions. In this work, protection strategies were investigated to prevent the dielectric barrier discharge plasma-induced inactivation of biocatalysts, using recombinant unspecific peroxygenase from Agrocybe aegerita( rAaeUPO), one of the most promising enzymes for plasma-driven biocatalysis. Treatment in oxygen-free atmospheres did not provide any advantage over treatment in synthetic air, indicating that the detrimental reactive species did not originate from oxygen in the plasma phase. Chemical scavengers were employed to eliminate undesired reactive species, without any long-term effect on enzyme lifetime. Similarly, chaperones, including the known stress response proteins Hsp33, CnoX, and RidA did not increase the lifetime of rAaeUPO. Immobilization of the biocatalyst proved effective in preserving enzyme activity. The residual activity of rAaeUPO after plasma treatment strongly depended on the specific immobilization support. Essentially complete protection for at least 15 min of plasma exposure was achieved with an epoxy-butyl-functionalized carrier. This study presents new insights into plasma–protein interactions and plots a path forward for protecting biocatalytic proteins from plasma-mediated inactivation.
Fiscal Decentralization, Corruption, and Income Inequality: Evidence from Vietnam

The objective of this research paper is to study the simultaneous relationship between fiscal decentralization, corruption, and income inequality among Vietnamese provinces. We use a balanced panel data set of 63 provinces/cities in Vietnam in the period from 2011 to 2018. The study used 3SLS-GMM (Three Stage Least Squares Generalized Method of Moments estimator) and GMM-HAC (Generalized Method of Moments Heteroskedastic and Autocorrelation Consistent estimator). Empirical evidence shows a strong simultaneous relationship: increased corruption will increase regional income disparities, income inequality, and increase fiscal decentralization. In addition, the results also suggest that an increase in per-capita income will reduce the level of corruption, or better control corruption of each province. The degree of increase in income inequality, which reduces fiscal decentralization, is the same for trade liberalization. All demonstrate that there is a simultaneous relationship between fiscal decentralization, corruption, and income inequality. In a region of high public governance quality, fiscal decentralization positively effects its economic growth. This issue will indirectly increase income inequality between provinces within a country. Our findings imply that a country’s fiscal decentralization strategy should be linked to improving corruption control and local governance effectiveness, indirectly improving income inequality between localities or regions.
Current Trends and Future Directions on Women CEOs/CFOs and Financial Reporting Quality

The aim of this paper is to review studies of women chief executive officers (CEOs) and chief financial officers (CFOs) in the context of financial reporting quality. By using electronic searches and keywords to identify relevant studies, a total of 22 published studies are identified over the period 2010-2020. Based on the review, two underpinning theories have been widely used in examining the effect of women CEOs/CFOs on the quality of financial reporting, namely, risk aversion theory and gender-ethics theory. In addition, a majority of the studies documented that women CEOs/CFOs lead to more conservative reporting and higher earnings quality. The findings underscore the importance to examine the gender issue in accounting literature and established a business and management case for women to attain the top position whether as a CEO or CFO. This paper also recommends to practitioners and regulators about the effect of having women as CEOs or CFOs on financial reporting quality as women are a pool of talent that is underutilized. In addition, this paper goes beyond a classic narrative review by suggesting future research avenues to examine further such issues in order to broaden the understanding of the role of women in accounting.
Photobiomodulation of Human Fibroblasts and Keratinocytes with Blue Light: Implications in Wound Healing

In recent years, photobiomodulation (PBM) has been recognized as a physical therapy in wound management. Despite several published research papers, the mechanism underlying photobiomodulation is still not completely understood. The investigation about application of blue light to improve wound healing is a relatively new research area. Tests in selected patients evidenced a stimulation of the healing process in superficial and chronic wounds treated with a blue LED light emitting at 420 nm; a study in animal model pointed out a faster healing process in superficial wound, with an important role of fibroblasts and myofibroblasts. Here, we present a study aiming at evidencing the effects of blue light on the proliferation and metabolism in fibroblasts from healthy skin and keratinocytes. Different light doses (3.43, 6.87, 13.7, 20.6, 30.9 and 41.2 J/cm2) were used to treat the cells, evidencing inhibitory and stimulatory effects following a biphasic dose behavior. Electrophysiology was used to investigate the effects on membrane currents: healthy fibroblasts and keratinocytes showed no significant differences between treated and not treated cells. Raman spectroscopy revealed the mitochondrial Cytochrome C (Cyt C) oxidase dependence on blue light irradiation: a significant decrease in peak intensity of healthy fibroblast was evidenced, while it is less pronounced in keratinocytes. In conclusion, we observed that the blue LED light can be used to modulate metabolism and proliferation of human fibroblasts, and the effects in wound healing are particularly evident when studying the fibroblasts and keratinocytes co-cultures.
Evolution of Collaborative Networks Supporting Startup Sustainability: Evidences from Digital Firms

The aim of this paper is to investigate whether startup evolution can be conceptualized in a life cycle model intended as an unpredictable sequence of stages, where startups need to find actors with whom to collaborate to acquire knowledge and resources supporting the effectiveness and the sustainability of their mission. The creation and implementation of collaborative networks is observed through the lens of the holistic approach to the entrepreneurial ecosystem, whose purpose is to build “bridges” between different actors through the creation of communities of best practices or entrepreneurial networks. The creation of a specific ecosystem is suggested to ease the new digital entrepreneurship generation toward acquiring an appropriate level of knowledge, skills, financial facilitations, and entrepreneurial culture. Following a multiple case study analysis based on nine successful Italian digital firms, the empirical evidence seems to confirm that firms collaborate with different actors in different stages, as knowledge and resource networks play a critical role in sustaining the evolution and success of new firms.

The Implications of SCAP Students’ Personal Values and New Ecological Paradigm View on Green Behaviour: A Perspective of Ecological Man in Simplified Norm Activation Model

The Economic Man in industrialization process regards the relationship between human-being and nature as economic relations of takes and gives, invest and produce. Thus, the economic man’s behaviours could cause the crisis of ecology. In 1950s, environment pollution broke out, environment hazard overflowed, resources exhausted, those phenomenon aroused widespread concern on environmental problems[1,2]. The conception of sustainable development was proposed in the report of the World Commission on environment and development in 1987[3]. Its definition consists of three parts: environment factor, social factor and economic factor. In the 1970s, environmentalists proposed that the industrialization process seriously damaged the environment, however, there are still no effective means to solve this problem from then to now. Owing to the increasing environment concern extend of public, the research on green behaviour in academia is expanding and deepening. With an enhancing awareness of environment protection, meanwhile, in order to detach with the ecological crisis stimulated by “economic man” awareness. In this study, hierarchical multiple regression method was used to analysis cross-sectional data collected with judgment sampling method from Chinese international students study in Study Abroad through Chinese Program (SACP), to verify that to cultivate “NEP world view” had postive mediation effect on relationship between different personal values and students’ behaviours of “sustainable development of low-carbon and energy-saving”. Students’ self-efficacy could accelerate the formation of NEP world view, while social influence able to promote students to behave green behaviours had been found in this research. These conclusions give policy makers a lot of useful enlightenment, and provide useful guidance for schools to improve students’ public environmental awareness, and for Chinese international students to carry out green behaviour in their daily life.
