Optimal scheduling of vehicle-to-Grid power exchange using particle swarm optimization technique

Electric vehicles (EV) are the inevitable future of the transportation industry considering the current energy scenario and all the incentives and benefits they provide. Nonetheless, EVs exhibit a novel characteristic of a distributed energy storage device (ESD) owing to their large onboard batteries. This feature of EV can be utilized to provide many ancillary services by the virtue of vehicle-to-grid (V2G) operation. One such service is the minimization of load variation on the grid. Two key challenges, concerning the practical execution of the V2G operation, are the availability of EVs for V2G operation and their ever-changing State of Charge (SOC). Due to the mobility of EVs as a transportation medium, their availability is highly uncertain. This paper addresses these issues by introducing a scheduling scheme for V2G power exchange by considering the stochastic nature of EV grid connectivity. This is done by first developing an optimization algorithm using the particle swarm optimization technique, with input data that best represents the stochastic nature of EV availability. Then, the performance of the algorithm is evaluated by conducting several case studies. The results obtained for various case studies by performing simulations are represented and elaborated. Finally, the statistical analysis of the results signifies that the proposed V2G scheduling scheme can substantially flatten the load profile. Apart from the algorithm itself, another novel nature of the paper lies within the wide range of analyses carried out to study the effect of such scheduling schemes. These studies include the effect on the SOC level of different EVs, the effect on price fluctuation, time complexity analysis of the algorithm, etc.
To what extent are the underlying concepts of integrated reporting applicable for hi-tech knowledge-based organizations?

Purpose The purpose of this study is to examine the proper structure for the integrated reporting of hi-tech knowledge-based organizations (KBOs); in particular, the authors evaluate the appropriateness of the concept and elements of integrated reporting for hi-tech KBOs. Design/methodology/approach The study uses an exploratory sequential mixed-method approach, including an initial qualitative case study, then an instrument development phase (Delphi), and finally, a quantitative survey. Findings The resulting analysis concluded that hi-tech KBOs have the potential to prepare a simplified, integrated report. The organization overview, governance, business model, strategies and resource allocation, performance, opportunities and risks are the content elements relevant to be included in the hi-tech KBOs annual report. However, the organization’s future outlook is not confirmed to be included. Due to liability and competitive concerns, organizations do not provide targets, forecasts, projections or even scenarios. Research limitations/implications Focus on a single country and a small sample of interviewees participated. Practical implications This paper concludes that the existing integrated reporting framework is useful for different types of organizations, but with some modifications. In addition, it analyzes how directors of Iranian hi-tech KBOs perceive and value content elements of integrated reporting. Social implications This paper suggests that the fulfillment of corporate transparency for Iranian hi-tech KBOs can be achieved by the policymaker’s support on integrated reporting. Originality/value Iran is swiftly moving toward a knowledge-based economy, and hi-tech KBOs will become the powerhouse of the economy. It is important to understand how managers of Iranian hi-tech KBOs perceive and value integrated reporting. The previous practical studies are not focused on Iranian firms and the impacts of integrated reporting on hi-tech KBOs and its implementation and effectiveness had not been studied before.
TAX AGRESSIVENESS IN FAMILY FIRMS: CAN CORPORATE GOVERNANCE MITIGATE IT?

Every taxpayers objectives is to minimize the tax paid to government. Few business tried to avoid tax more agressively than the others. This research will tried to investigate whether the family firms are more tax agressive compare to non family firms. Tax agressiveness might be reduced if there is a working governance structure. This research will also investigate whether the governance structure (i.e size of board of director, proportion of independent director, external audit firms, and audit committee) would significantly reduced the tax agressiveness. To control the results, researcher used size, profitability and leverage. This research was quantitative explanatory research. Researcher will analyzed 15 out of 57 family own-business in Indonesia, and make a comparison with non family firms. Researcher examined the financial statements and annual report from year 2011 – 2015. The research will used multiple regression analysis as a data analysis tools. This research will produce tax agressiveness analysis of family firms, non family firms, and combination of both firms. The research showed that, contrast to the non family firms, family firms had agressive tax avoidance scheme. The research also showed that corporate governance in family company in fact, increasing the agressiveness o tax avoidance, while non family firms corporate governance reduced the agressiveness of tax avoidance. Overall this research showed that family business need to improve the governance structure to control its agressive tax avoidance. Keywords: Corporate Governance, Family Business, Ownership, Tax Avoidance.
Unexpected High Absorption of Atmospheric Aerosols Over a Western Tibetan Plateau Site in Summer

The assessment of atmospheric aerosol radiative effects in the Tibetan Plateau (TP) suffers from large uncertainties due to limited understanding of aerosol physicochemical properties. To quantify aerosol optical properties, size distributions, and chemical compositions in the western TP, an intensive field campaign was carried out at Shiquanhe National Reference Climatological Station from July 8 to August 2, 2019. Unexpected low single scattering albedo (SSA) at 870 nm was found for the fine aerosols with an average value of 0.73 ± 0.18. SSA was even lower than 0.60 in the morning when fine aerosols peaked, indicating high absorption of the fine aerosols induced by anthropogenic activities. Coarse mode aerosols accounted for 70.58% ± 14.98% of the total volume concentration and mineral dust was the most abundant species in total suspended particles with a mass fraction of 48.7%. Fine mode aerosol concentrations showed little dependence on wind speed while coarse mode aerosols and metallic element concentrations exhibited strong positive correlations with wind speed, indicating the importance of wind‐blown dust particles. The present study for the first time quantified key aerosol parameters in the western TP and unexpected high absorption of atmospheric aerosols were found over the site in summer. Our results suggest the need to carefully consider the radiative effects caused by aerosol absorption in the TP region.
Ego Depletion and Charitable Support: The Moderating Role of Self-Benefit and Other-Benefit Charitable Appeals

Abstract This research investigates the interaction between ego depletion (a state of reduced self-regulatory resources) and different types of charitable message appeals upon subsequent charitable support. Three experiments compare the time donation intent and actual monetary donations of depleted (vs. non-depleted) individuals who have been exposed to either a self-benefit message, highlighting the gains to be accrued to donors themselves, or an other-benefit message which focuses on the welfare of beneficiaries. The results show that when people are depleted, self-benefit messages are more effective than other-benefit messages in generating charitable support. When people are not depleted, the opposite pattern is observed. It appears that generosity among depleted people is self-seeking. As a processing mechanism, we show that depleted individuals perceive self-benefit messages as more appealing than the other-benefit messages. This research demonstrates that charities can maximize donations by advertising other-benefit messages in the morning and then self-benefit messages in the evening, given that depletion occurs naturally over the course of the day.
Nano-TiO2'in tuzlulukta arpa fidelerinin ilk gelişim aşamaları üzerine etkileri

Received 25 October 2020 Received in revised form 05 February 2021 Accepted 08 February 2021 The most important development period in cereal plants is the initial stage, that is, seed germination and early seedling development. Even if the barley is thought to be a partially salt-tolerant plant, it may be severely affected when exposed to salinity at initial developmental periods. Pre-treatment and preparation of seeds before sowing have an important in agriculture. Nano-seed priming treatment is a new approach used to increase germination, emergence and seedling growth recently. In this study, the effects of nano-TiO2 (0, 100, 200 mg L n-TiO2) pre-application and ongoing/combination application under salinity (0, 100, 200, 300 mM NaCl) on germination and early seedling growth of barley plants were investigated. Root lengths (RL, mm), germination rates (GR, %), radicle emerging (RE, %), number of coleoptiles (CN) were measured depending on the day (1, 2, 3 days). At the end of the third day, seedling fresh and dry weights (FW,DW mg) were measured. The relative growth index (RGI) of root and mean germination time (MGT) were calculated. It was determined that the application of 100 mg L n-TiO2 increased root length and RGI compared to control groups. It was observed that the application of 100 mg L n-TiO2 significantly increased the germination percentage, biomass and root length especially in 100 mM salt conditions. Also, 100 mg L n-TiO2 increased the RE too in 100 mM salt conditions (1st day). In this study, it was determined that 300 mM NaCl was inhibitory dose, and also germination remained below 20% in 200 mM NaCl in all groups.

Perilaku UMKM Terhadap Pelaksanaan Pemungutan Pajak UMKM Dengan Menggunakan Self Assessment System

Abstract - The implementation of MSME tax collection with the Self Assessment System is a tax collection system by calculating, paying and reporting by yourself by giving confidence to taxpayers based on applicable laws and regulations. This study aims to 1) determine the implementation of the implementation of the self-assessment system in Makasar District, East Jakarta; 2) analyzing the understanding of the taxation knowledge of the UMKM taxpayers, 3) analyzing the implementation of the MSME taxpayer obligations 4) analyzing the tax awareness of taxpayers' sensitivity. This type of research is qualitative descriptive by means of direct primary data collection through interviews with 10 taxpayer informants of MSME actors. The results of his research indicate that the implementation of the self-assessment system has not been going well and more intensive assistance is needed. This is due to the lack of public awareness of taxation and lack of understanding of taxation knowledge. There are 4 informants who run the self-assessment system, 2 of which are assisted by tax consultant services and 6 other informants have not implemented the self assetment system properly
Natural resource governance, accountability and legitimising propensity: insights from Ghana's oil and gas sector

PurposeThis study explores Ghanaian views about accountability discharge by firms and government in the context of the nation's newly discovered oil and gas resources. The research focusses on a range of issues relating to stakeholder interaction, communication flows and the impact of decision-making on Ghanaian lives, as perceived by individuals on the ground.Design/methodology/approachThe paper adapts elements of legitimacy theory to interpret the outcome of a series of semi-structured interviews with members of key accountee and accountor groups including citizens and representatives of the state and private firms in the oil and gas industry in Ghana.FindingsThe results indicate that rather than attempting to effect substantive accountability discharge, Ghana's government and oil and gas firms employ a wide range of legitimation strategies despite the apparently complete absence of the accountee power normally seen as driving the need for social contract repair.Research limitations/implicationsThe findings suggest that accountability discharge in Ghana is cursory at best, with several legitimising strategies in evidence. The representatives from state institutions appear to share some of the concerns, suggesting that the problems are entrenched and will require robust enforcement of a strengthened regulatory approach to effect meaningful change.Originality/valueThis paper contributes to the literature on the discharge of institutional accountability by building on earlier conceptualisations of legitimacy theory to explore perceptions around a recent natural resource discovery. The analysis highlights grave concerns regarding the behaviour of state and corporate actors, one that runs counter to sub-Saharan African tradition.
Light-induced annihilation of Frenkel defects in organo-lead halide perovskites

In spite of the unprecedented advances of organohalide lead perovskites in optoelectronic devices, many of the characteristics of this class of materials remain poorly understood. Several experimental hints point to defect migration as a plausible mechanism underlying such anomalous properties. Here we present an experimental and theoretical investigation combining measurements of PL rise dynamics at varying temperatures with first principles computational modeling of defect migration under light irradiation. We propose a model in which light irradiation promotes the annihilation of VI+/Ii− Frenkel pairs, which we show to be relatively abundant in polycrystalline MAPbI3. This partly restores a non-defective crystalline environment and eliminates the trapping centers associated with such defect pairs. The PL rise time dynamics at varying temperature provide an activation energy consistent with that calculated for migration of iodine defects, supporting the proposed model. We further illustrate a synergistic effect of ion/defect migration and lattice dynamics, with local reorientation of the methylammonium cations assisting the migration of charged defects. Our results provide the interpretative basis for further investigating the unusual light-induced modifications characterizing organohalide perovskites.
MDR1 Genotypes and Haplotypes Are Closely Associated with Postoperative Fentanyl Consumption in Patients Undergoing Radical Gastrectomy

Fentanyl is a powerful opioid analgesic, and its analgesic effect is greatly different among individuals. This study was aimed at exploring the effects of multidrug resistance gene-1 (MDR1) genetic variation on postoperative fentanyl consumption. A total of 135 patients, who planned to undergo radical gastrectomy with general anesthesia, were studied. The subjects received patientcontrolled analgesia (PCA) by intravenous fentanyl within 48 hours after operation and maintained a numerical rating scale (NRS) score ≤ 3. The consumption and side effects of fentanyl were recorded within 24 hours and 48 hours after the operation. Single nucleotide polymorphisms (SNPs) of all patients with MDR1 1236C>T, 2677G>T/A, and 3435C>T were screened by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) or DNA sequence analysis after PCR. There was no difference in postoperative fentanyl consumption among patients having 2677G>T/A and 3435C>T polymorphisms (all P > 0:05). MDR1 1236C>T polymorphisms and haplotypes combined by three SNPs, however, significantly affected postoperative fentanyl consumption (all P < 0:05). Moreover, 1236TT genotype carriers consumed more fentanyl during 24 hours (P = 0:038) and 48 hours (P = 0:003) postoperatively. The MDR1 TTT haplotype carriers needed more fentanyl compared with the CGC haplotype carriers during the first 48 hours after surgery (P = 0:017). Nausea, vomiting, and dizziness were not found to have significant differences among the above three SNPs and their haplotypes (P > 0:05). MDR1 1236C>T polymorphism and haplotypes were factors contributing to the individual variability in postoperative fentanyl consumption.
In vitro Antitrypanosomal Activity and Phytochemical Screening of Selected Acacia Plant Species Aqueous Methanol Extract

Trypanosomiasis has been recognized as a scourge in sub-Saharan Africa for centuries and chemotherapy of the disease still remains unsatisfactory. This study is to explore an alternative source of antitrypanosomal agents from the stem bark of four Acacia species; Acacia nilotica, Acacia sieberiana, Acacia geradii and Acacia hockii. Dried stem bark of each plant was pulverized and extracted with 98% methanol by maceration. Phytochemical screening was carried out followed by in vitro testing of extracts on the motility of Trypanosoma congolense maintained in Ringer solution. Motility assessment of trypanosome was carried out after exposure with varied concentrations of the extracts for 2 hours. Thereafter, infectivity test was carried out using albino mice. Seventy-two mice, divided into twenty-four (24) groups of three animals were each inoculated with 100µl of the mixture containing the varying extract concentrations intraperitoneally. Berenil was used as standard drug control. Establishment of infection and subsequent Parasitaemiawere monitored in the animals for 60 days. The Phytochemical assay revealed the presence of anthraquinones, tannins, glycosides, cardiac glycosides and terpenes in all the extracts. Saponin was only present in Acacia nilotica and Acacia geradii. Incubation of parasites with each of the four acacia species recorded cessation in parasite motility which was concentration dependent. The highest concentration 20 mg/ml showed the highest effect within fifteen (15) minutes of incubation which was similar to the Berenil incubated control. However, lower doses (0.005 and 0.00005) mg/ml did not show difference from the non extract incubated negative control. Incubation of T. congolense with Acacia nilotica, Acacia sieberiana, Acacia geradii and Acacia hockii at 20, 10 and 1 mg/ml inhibited the ability of the parasites to establish infection in the albino mice as compared the standard control drug. The results indicate that the methanolic stem extracts of the four acacia species possess antitrypanosomal activity with potentials for the treatment of trypanosomiasis.
Display interface design for rollers based on cognitive load of operator

Optimizing a display interface design for rollers is the focus of this study, in which the effects of cognitive load of the operator are taken into consideration, which greatly contribute to acquiring interface information accurately and enhancing cognitive efficiency. To reduce the cognitive demand of the operator, a commonly used generic display interface is modified in this study. Three methods are used to measure the cognitive load, including subjective (NASA Task Load Index) and physiological (eye movement) measurements and through task performance. These three measurements are used with two groups of subjects: those who view the original and those who are given the modified version during four given tasks. The findings show that the modified interface has a significant impact on eye movement and completion time of the four tasks. After a comprehensive analysis of the results from the three types of measurement, it is found that the modified interface is less cognitively demanding than the original interface and allows a higher cognitive performance, which accordingly demonstrates that the modifications made are effective in reducing cognitive load. This study therefore provides the scientific basis for advancing interface designs and evaluating the display interface designs for engineering equipment.
Ultrafast structural dynamics in condensed matter

Basic processes in Nature such as phase transitions or (biochemical reactions are connected with structural changes of matter. The spatial rearrangement of electrons and nuclei, the formation and breaking of chemical bonds, as well as atomic and molecular motions underlie those events. In liquids and solids, atoms and molecules couple through a variety of short- and long-range interactions, leading to structural changes on ultrafast time scales between 10 - 1 5 s [1 femtosecond (fs)] and 10 - 1 2 s [1 picosecond (ps)]. Nonlinear optical spectroscopy with femtosecond light pulses represents the only technique for inducing and probing such events in real-time, similar to recording a sequence of "snapshots« in photography on much slower time scales.
Proces wymiany zębów u wybranych grup ssaków w ujęciu ewolucyjnym

Dental replacement in mammals is one of the most important evolutionary processes in these vertebrates. First mammals had many primitive features inherited from the reptilian ancestors. Already at a very early stage the teeth diversified into the incisors, canines, premolars, and molars. A tendency to reduce the tooth count also appeared. The groundbreaking innovation was the emergence of diphyodont replacement pattern (two generations of dentition, deciduous and permanent), which is a characteristic feature of mammals, in contrast to the polyphyodont reptiles. The evolution of dental exchange went towards the decreasing number of teeth being replaced. This paper aims at providing readers with information on main stages of the process initiated over 200 million years ago, which resulted in a notable diversification of both the dentition patterns and dental replacement types, observed in living mammals. Key words: dental replacement, diphyodonty, mammalian evolution, polyphyodonty
