The Effect of Perceived Cost, Trust, Usefulness, And Customer Value Addition on Intention to Use of Go-Pay Mobile Payment Services In Small Traders

This research is based on the phenomenon of the problem of the widespread use of payment methods based on financial technology (fintech), namely mobile payments which contribute to the circulation of electronic money reaching Rp.47. 2 trillion in December 2018. However, there are mental barriers that increasingly hinder the intention to adopt this fintech-based service. One of the largest providers of mobile payment is Go-Pay who owned by Go-Jek. These barriers are in the form of costs, trustworthiness, usefulness, benefits, and experiences that will be obtained. The aims of this study are to identify the effects of Perceived cost, Perceived trust, Perceived usefulness, and Perceived customer value addition on Intention to Use Go-Pay Mobile Payment services on Small Traders. The samples used were 120 respondents of small traders. This study uses multiple linear regression analysis to identify the relationship between variables. These results indicate that the perceived cost, perceived trust, and perceived customer value addition have a significant positive effect on Intention to use, while perceived usefulness has a negative and insignificant effect on Intention to use. This research is expected to be able to provide benefits for mobile payment providers in developing ways to attract small merchant partners for their mobile payment facilities.
The acoustics and unsteady wall pressure of a circulation control airfoil

by Jonathan C. Silver A Circulation Control (CC) airfoil uses a wall jet exiting onto a r ounded trailing edge to generate lift via the Coanda e ff ct. The aerodynamics of the CC airfoil have been studied extensively. The acoustics of the airfoil are, however, muc h less understood. The primary goal of the present work was to study the radiated sound and un steady surface pressures of a CC airfoil. The focus of this work can be divided up into three main categories: characterizing the unsteady surface pressures, characterizing the r adiated sound, and understanding the acoustics from surface pressures. The present work is th e first to present the unsteady surface pressures from the trailing edge cylinder of a circu lation control airfoil. The autospectral density of the unsteady surface pressures at vario us locations around the trailing edge are presented over a wide range of the jets momentum coe fficient. Coherence of pressure and length scales were computed and presented. Single m icrophone measurements were made at a range of angles for a fixed observer distance in t h far field. Spectra are presented for select angles to show the directivity of the ai rfoil’s radiated sound. Predictions of the acoustics were made from unsteady surface press ures via Howe’s curvature noise model and a modified Curle’s analogy. A summary of the cur rent understanding of the acoustics from a CC airfoil is given along with suggestion s for future work.
An Experimental Study of Passive Control of Hypersonic Cavity Flow Oscillations

Abstract : An experimental study of open cavity flow has been made in a high Reynolds number, Mach 5 turbulent boundary layer. The majority of measurements made were of fluctuating wall pressures. The objectives were: (1) examine how effective changes in front and rear wall geometry were at attenuating the pressure oscillations, (2) explore how impingement of a shock wave (variable strength and position) the cavity flow, and (3) how stores (different geometries and positions) affected the cavity flow. In addition, techniques which were judged effective at attenuating pressure oscillations for the empty cavity were used with shock impingement and with stores in order to explore their effectiveness under perturbed flow conditions. The results show that vented and slotted walls, and spoilers are ineffective. A 3-D rear wall (swept in both planes and symmetric about the center line) attenuated the strongest oscillations by factors of up to 7 compared to the baseline rectangular cavity. Regardless of shock impingement position, shock strength, store position, store dimensions, store to cavity volume ratio and asymmetric store arrangement the cavity oscillation frequencies remain essentially unchanged. Based on the mean and rms Pressure distributions (whose magnitude varies substantially but whose basic shape does not change significantly) and surface flow patterns it appears that the essential flow structure also remains largely unchanged. These similarities suggest that control techniques developed for the empty cavity flow should be effective with shock impingement or store release. Tests using two passive control rear walls in perturbed cavity flow support this conclusion.

Progress in Perovskite Solar Cells towards Commercialization—A Review

In recent years, perovskite solar cells (PSCs) have experienced rapid development and have presented an excellent commercial prospect as the PSCs are made from raw materials that are readily and cheaply available depending on simple manufacturing techniques. However, the commercial production and utilization of PSCs remain immature, leading to substantial efforts needed to boost the development of scalable fabrication of PSCs, pilot scale tests, and the establishment of industrial production lines. In this way, the PSCs are expected to be successfully popularized from the laboratory to the photovoltaic market. In this review, the history of power conversion efficiency (PCE) for laboratory-scale PSCs is firstly introduced, and then some methods for maintaining high PCE in the upscaling process is displayed. The achievements in the stability and environmental friendliness of PSCs are also summarized because they are also of significance for commercialization. Finally, this review evaluates the commercialization prospects of PSCs from the economic view and provides a short outlook.
Comparison of Mathematical Methods for Compensating a Current Signal under Current Transformers Saturation Conditions

Current measurements from electromagnetic current transformers are essential for the construction of secondary circuit systems, including for protection systems. Magnetic core of these transformers are at risk of saturation, as a result of which maloperation of protection algorithms can possibly occur. The paper considers methods for recovering a current signal in the saturation mode of current transformers. The advantages and disadvantages of methods for detecting the occurrence of current transformers core saturation are described. A comparative analysis of mathematical methods for recovering a current signal is given, their approbation was carried out, and the most promising of them was revealed. The stability and sensitivity of recovery methods were tested by adding white noise to the measured signal and taking into account the initial flux density (remanent magnetization) in the current transformers core. Their comparison is given on the basis of angular, magnitude, and total errors at a given simulation interval.
Effects of treeshelter on seedling performance: a meta-analysis

ABSTRACT Treeshelters are used in a variety of environments for forestry and forest restoration purposes. Although their use is often effective, in some cases treeshelters are ineffective. To clarify the effects of treeshelters on seedling performance, a systematic literature review and meta-analysis was conducted. Of the 296 studies related to treeshelters, 139 studies were suitable for extraction of data on mortality rate, browsing damage rate, height growth, or diameter growth. The quality of the literature did not affect the results of the meta-analysis. Mortality, browsing damage, and height growth were positively affected by treeshelters in many subgroup analyses, but diameter growth did not conform with the perceived inhibitory effect of treeshelters. Regarding conifer species, treeshelters had no effect on mortality rate and non-ventilated treeshelters promoted diameter growth. However, many subgroup analyses showed publication bias as indicated by the significantly fewer negative-effect studies. Therefore, the effects of treeshelters may be overestimated although the effects revealed by the meta-analysis were reasonable from the viewpoint of plant physiological reactions. Heterogeneity was high in most of the subgroups, suggesting that factors other than the analyzed subgroups may contribute to the variance in treeshelter effects. Studies on treeshelters are concentrated under specific conditions, such as on species of the genus Quercus and a temperate climate. Thus, other under-represented conditions are considered to constitute research gaps. Further studies in these research gap areas are required to perform a meta-analysis with low heterogeneity.
CRASH TESTING OF VARIOUS TEXTURED BARRIERS

Eight crash tests were conducted on seven different patterns of textured barriers. The test articles had the following textured surfaces: a deep cobblestone (extending to the grade line), a 19-mm-deep fluted rib angled to 45 deg, a "Mission Arch," a "Cobble Reveal" (deep cobblestone top section with a 610 mm band of light sandblast along the bottom), a Drystack stone, a Stone Ground Fractured Granite, and a shallow cobblestone. All test articles had a "base" profile similar to that of a Type 60 concrete barrier. The deep cobblestone, fluted rib at 45 deg, and Mission Arch barriers were 1220 mm high while all others were 1422 mm high. All testing was completed under National Cooperative Highway Research Program Report 350 Test Level 3 guidelines with 2000-kg pickup trucks and 820-kg passenger vehicles. The results of all tests (pass or fail) were used to develop a set of guidelines that may be used to judge the crashworthiness of future design submissions. The Mission Arch, Cobble Reveal, Drystack, and Stone Ground Fractured Granite textures as tested in this report are recommended for approval on California highways requiring TL-3 longitudinal barriers. The deep cobblestone, shallow cobblestone, and fluted ribs at 45 deg are not recommended.
Silver-Nanoparticle-Mediated Therapies in the Treatment of Pancreatic Cancer

Pancreatic cancer is an extremely aggressive disease for which patient prognosis is poor and survival is extremely unlikely. It is an extremely under-represented cancer in the research field because of the dense tumors formed and complexities surrounding treatment requirements. The use of nanomedicines in cancer therapy has been explored over the past few decades. Such nanomedicines are slowly coming to fruition in the clinical setting. One such platform that may possess promise in the fight against pancreatic cancer is the use of colloidal silver. Silver nanoparticles have shown potential in other cancer types over a host of treatment strategies, and these are likely to be translatable into pancreatic cancer. This review will focus on the potential use of silver nanoparticles in pancreatic cancer therapy, reporting on a range of different strategies being employed that may be directly applicable in the improvement of clinical outcomes for pancreatic cancer patients.
Wireless Passive High-Temperature Sensor Readout System for Rotational-Speed Measurement

Rotational-speed measurement in harsh environments is an important topic. However, the high rotation results in rapid frequency variations in the signals of a sensor and changes in physical properties under extreme thermal circumstances cause significant difficulties in reading signals. To address this problem, we adopt wireless passive measurement methods to design a special characteristic signal circuit module that achieves precise measurement of rotational speed at high temperatures. The sensor and the readout system include a variable frequency source, a readout antenna, and a radio frequency demodulation circuit. Herein, a demodulation detector of the signal conversion circuit is designed and used in the envelope detection module of the single sideband demodulation method. In addition, a conversion circuit test platform for high-temperature environment sensor signal is developed. From the testing, the output signal demodulation of the sensor was observed under a maximum temperature of 700°C with error less than 0.12%. The new sensor and measurement method do not require physical leads and achieve wireless noncontact accurate measurement of rotational speed at high temperature.
Protection of Indonesian Migrant Workers after Moratorium Policy on Consignment of Migrant Workers and its Impact to Indonesia Saudi Arabia Relations

Indonesian government implement the moratorium on consignment of its migrant workers to Saudi Arabia after a migrant worker whose name is Ruyati was sentenced to death in Saudi Arabia in 2011. The moratorium is expected to ensure the safety of migrant workers. However, it has further impacted on migrant workers and becomes an issue of Indonesia - Saudi Arabia relations. We investigate the efforts of protecting Indonesian migrant workers from the Indonesian diplomatic representatives and its impacts on Indonesian relations with these countries. We conduct interviews with the representatives of the Indonesian Government and Indonesian migrant workers in Saudi Arabia. The findings are analysed with human security perspective, responsibility to protect (R2P) in the context of international migration. We argue that protection efforts based on human security to those migrant workers could leverage the position of Indonesia in its relations with Saudi Arabia. The problem of Indonesian migrant workers in Saudi Arabia is a complex issue, therefore we suggest further research to highlight the issue from the perspectives of the workers and cultural differences between those two nations.
On Ya Bike? A Review of the Christchurch Cycleway Network Business Case

Transport consulting firm QTP Ltd has estimated that the proposed Christchurch cycleway network provides $8 of economic benefits for every dollar invested; i.e., a benefitcost ratio (BCR) of 8.0. As a result, the Christchurch City Council has labelled the network’s business case as “proven”. However, this “proven” business case has been the subject of precisely zero public scrutiny. We provide that scrutiny and find, in contrast to QTP, that the cycleway network is a doubtful proposition from an economic efficiency perspective, having an estimated BCR in the 0.7-1.6 range, at best.
INFLUENCE OF SILICON IN THE ATMOSPHERE ON OSTEOARTHRITIS CLINICAL COURSE

Osteoarthrosis (OA) is the most common diseases of the musculoskeletal system which cause an enormous medical and social harm on the patients and the society. The risk factors of the OA development are high atmospheric concentrations of silicon compounds (Si). The purpose and the objectives of the study were the assessment of the role of silicon microelementosis in OA. The study included 105 patients with OA, with an average age of 44 and 81 years old, in the proportion of men and women as 1:5, with the duration of the disease 10 years. Using the method of atomic absorption spectrometry we determined Si content in blood and in hair, evaluated the level of the pollution with Si-containing compounds. It has been found out that silicon imbalance was typical in OA which is manifested by increasing of Si content in blood. Air pollution with silicon pollutants affects negatively the incidence of OA in regions which is accompanied by Si accumulation in patients’ hair with a subsequent impact on the rate of articular syndrome progression, the development and the severity of subchondral sclerosis, ligamentosis of knee joints, reactive synovitis and cartilage bodies, and in relation to spondylopathy inhaled Si compounds have a certain protective action.

Measuring true stress–strain curves of cylindrical bar samples with mirror‐assisted multi‐view digital image correlation

This paper proposes to measure true stress–strain curves at the necking region of cylindrical bar samples by using an advanced mirror‐assisted multi‐view digital image correlation (MV–DIC) technique. The mirror‐assisted MV–DIC can measure the panoramic shape and deformation fields of a cylindrical bar sample with only a single two‐camera stereo‐DIC system and two planar mirrors. The measured panoramic shape enables accurate determination of the cross‐section area and radius of curvature at the necking region by using cylindrical or torus fitting. The retrieved cross‐section area and radius of curvature at the necking region further enable the measurement of the true stress–strain curves and even the Bridgman's correction of the true stress.
Transcriptome Analysis of a Cotton Cultivar Provides Insights into the Differentially Expressed Genes Underlying Heightened Resistance to the Devastating Verticillium Wilt

Cotton is an important economic crop worldwide. Verticillium wilt (VW) caused by Verticillium dahliae (V. dahliae) is a serious disease in cotton, resulting in massive yield losses and decline of fiber quality. Breeding resistant cotton cultivars is an efficient but elaborate method to improve the resistance of cotton against V. dahliae infection. However, the functional mechanism of several excellent VW resistant cotton cultivars is poorly understood at present. In our current study, we carried out RNA-seq to discover the differentially expressed genes (DEGs) in the roots of susceptible cotton Gossypium hirsutum cultivar Junmian 1 (J1) and resistant cotton G. hirsutum cultivar Liaomian 38 (L38) upon Vd991 inoculation at two time points compared with the mock inoculated control plants. The potential function of DEGs uniquely expressed in J1 and L38 was also analyzed by GO enrichment and KEGG pathway associations. Most DEGs were assigned to resistance-related functions. In addition, resistance gene analogues (RGAs) were identified and analyzed for their role in the heightened resistance of the L38 cultivar against the devastating Vd991. In summary, we analyzed the regulatory network of genes in the resistant cotton cultivar L38 during V. dahliae infection, providing a novel and comprehensive insight into VW resistance in cotton.

Strategic Alignment and Business Performance Model within the Corporate Governance

This paper aims to explore and analyse a strategic alignment and business performance model within the corporate governance. The objective of our research is to debate on the actual organizational needs in terms of reshaping corporate business strategy in connection with the business performance, taking into consideration new IT developments and trends. A research model with seven dimensions for strategic alignment and two dimensions for business performance is considered. A questionnaire including forty-three items is developed based on a content analysis of the previous literature. The qualitative research construct is further tested through two in-depth interviews with a Chief Operations Officer of a Global Competences Centre in the insurance industry and a Managing Director of a Cloud Data Management Company in the software industry. Our contribution is the comparative analysis of perceptual data in terms of management policies related to the strategic alignment in relation with the business performance within corporate governance. The insights of the interviews reflect our choice to operationalize the strategic alignment model construct and complement the conclusions of previous research in the field of business strategy and performance.
