PENGARUH KECEPATAN TOOL PADA DISSIMILAR METAL ALUMINIUM 1100 DAN 5052 TERHADAP KUALITAS HASIL PENGELASAN DENGAN METODE LAS GESEK PUNTIR (FRICTION STIR WELDING)
Authors: Sukamana Irza
Published: November 2020

Pengelasan merupakan proses penggabungan dua atau lebih logam dasar yang disatukan di permukaan kontaknya dengan atau tanpa zat penambah maupun pengisi.Pengelasan terbagi menjadi dua kategori utama yaitu Liquid-State Weldingdan Solid-State Welding. Friction Stir Weldingmerupakan salah satu contoh pengelasan Solid-State Welding (Non-Fusion Welding).

 

Aluminium adalah logam yang paling banyak terdapat di kerak bumi, dan unsur ketiga terbanyak setelah oksigen dan silikon. Aluminium adalah suatu unsur kimia yang terletak pada golongan 13 periode 3 dengan lambang Al dengan nomor atom 13. Aluminium terbuat dari 66% bauksit dan 33% tanah liat. Aluminium merupakan salah satu material yang sering digunakan sebagai bahan baku sambungan untuk pengelasan Friction Stir Welding.

 

Friction Stir Welding (FSW) atau Las Gesek Puntir adalah proses pengelasan gesek yang memuntir tool dengan memanfaatkan energi panas dan penekanan tanpa zat penambah maupun pengisi hingga terjadi perubahan fasa pada logam dasar. Parameter proses pengelasan yang dilakukan pada penelitian ini adalah laju translasi tool yaitu, 16 mm/menit dan 22 mm/menit dengan putaran tool 2000 rpm menggunakan jenis indentor changing spiral form. Adapun pengujian yang dilakukan yaitu, pengujian tarik, pengujian kekerasan dan pengujian komposisi kimia.

 

Hasil dari penelitian ini adalah ditemukan bahwa laju translasi tool, perlakuan panas dan kecepatan pengelasan sangat mempengaruhi sifat – sifat mekanik aluminium seri 1xxx dan seri 5xxx yang telas dilas. Laju translasi 22 mm/menit akan meningkatkan nilai kekerasan dan kekuatan tarik yang lebih baik dibandingkan dengan laju translasi 16 mm/menit, namun tidak terlalu berdampak signifikan terhadap unsur-unsur kimiai di dalamnya.

Abstrak

 

Biodiesel merupakan bahan bakar terbarukan dengan properties hampir menyerupai diesel fuel dan dapat digunakan pada motor diesel direct injection tanpa perubahan sistem bahan bakarnya. Bahan baku biodiesel yang tersedia di Indonesia antara lain kelapa, jatropa curcas dan minyak goreng bekas dapat diubah menjadi biodiesel melalui proses esterifikasi. Penelitian numerik menggunakan FLUENT 6.2 ini dilakukan pada model ruang bakar mexican hat untuk mengetahui distribusi ukuran droplet serta visualisasi semprotan dari ketiga jenis biodiesel tersebut. Pemodelan turbulen yang digunakan adalah RNG k-ε karena dapat memprediksi struktur large scale yang diproduksi oleh semprotan dan squish flow sedangkan pemodelan break-up menggunakan WAVE karena semprotan ini berlangsung dalam angka Weber yang tinggi. Hasil numerik membuktikan bahwa biodiesel minyak goreng bekas memiliki droplet berdiameter lebih besar daripada biodiesel kelapa atau jatropa curcas karena memiliki tegangan permukaan tinggi. Diameter partikel akan berkurang saat penetrasi semakin jauh karena pengaruh gaya aerodinamik yang bekerja pada droplet dan droplet tadi pecah setelah bertumbukan dengan dinding piston.

Published: November 2020

We focus on the effect of site parameters, also called site proxies, on the variation of the amplification factor. This latter, named Fourier Amplification Factor (FAF) is defined as the ratio of the Fourier transform of the seismic motion at surface and at bedrock. For this study, the wave propagation theory is used limited to 1D linear viscoelastic domain. At this effect, a set of FAF, is established for a set of 858 real profiles. From there, the site parameters are also derived, it is necessary to mention that the FAF can be computed in independent manner of seismic signals which it is applicable only on linear domain.In Nuclear Power Industry application, the FAF is mostly used and can be approximated by limited number of site proxies. As the usual code practice implies a lower number of site proxies (generally 1, sometimes 2) as UBC97 or EC8, a sensitivity analysis is conducted to identify the "best performing" site parameters. The results show that by far, using the six site proxies lead to a better prediction of FAF. However if we have to use one single site parameter, results show that the best one is the overall resonance frequency (f0). In the case when we intend to use two site parameters built from the average shear wave velocity over the upper 30 m (Vs30) and the resonance frequency (f0) which are preferred and give an important variance reduction superior than 61%. In the result, a new formula has been established.

Institutional Aspects of Choice and Application of Audit Procedures
Authors:   “Institute of Agrarian Economics” National Scientific Centre, Kyiv, Ukraine, Melnyk Kateryna
Published: November 2020

The purpose of the article is to identify the substantive characteristics and possibilities of application of audit procedures in the context of the implementation of its functions as of a public institute. On the base of application of the method of abstraction, it is established that the main elements of the audit institution that affect the features of planning, implementation and evaluation of audit procedures are the institutions, the subject of the audit and the functional content of the procedures. It’s found the following types of procedures: providing, implementation, identification, evaluation, comply with ethical requirements and quality control. It is determined that there are differences in the procedures performed by public and independent audit entities. The reason for such differences is the integration of public audit entities into the public resource management system. Differences are characterized, in particular, by the lack of procedures in the state audit for compliance with ethical requirements and quality control. Instead, independent auditing entities are delegated by law to perform procedures that are not directly related to audit tasks. The subject area of the audit performed by state institutions is limited by the use of state resources. This makes it impossible to use the results of the audit by public groups that do not participate in these processes. The functional workload of audit procedures determines the possibility of their use for the implementation of executive and information functions by the subjects of state audit, as well as the information function of audit firms and private auditors. The problem of restrictions on using of audit procedures in the audit institute functioning context is proposed to be solved by amending the regulations. Such changes will help expand the powers of public audit entities in the selection and application of audit procedures.
Unified Reporting on Personal Income Tax and Unified Social Tax: Simplification or Additional Complication of Conditions for Business Operation?
Authors:   Lviv Polytechnic National University, Lviv, Ukraine, Boichuk Andrii
Published: November 2020

In the context of the reform of the tax system and the accounting and reporting system, as well as the integration of Ukraine with the European Community, the issue of simplifying the conditions for doing business, building an effective and understandable system for administering taxes and other duties acquire special significance. One of the important aspects of reforming the tax system of Ukraine is the introduction of unified reporting on personal income tax and unified social tax. The purpose of the article is to identify the positive and negative aspects of the process of reforming the reporting on personal income tax and unified social tax and scientifically substantiate the structure of such unified reporting. The existing forms of reporting on personal income tax and unified social tax, proposed by government agencies, were analyzed. In addition, the unified reporting models from these taxes proposed by scientists were critically assessed by the author. It was found that such indicators as the presence of Ukrainian citizenship, gender and the sign of a new job, do not participate in the process of monitoring the completeness of tax payments. Therefore, it is impractical to fill in these indicators for each employee, and it is enough to submit the total number and structure of these indicators on the reporting title page. The opposite situation exists with the military tax, which is advisable to display for each employee in the reporting for more effective control over its accrual and payment. The author has improved the structure of unified reporting on personal income tax and unified social tax, which will reduce the time spent on filling out such reports, increase the efficiency of control by the fiscal authorities and simplify the process of processing unified reporting data. The main advantages of the proposed form of unified reporting are: significant reduction in the number of indicators; simplicity and compactness; personalized registration of military tax; ease of filling and processing information.

Published: November 2020

The emergence and rapid development of the cryptocurrency market necessitated its organization and legal regulation. Today in Ukraine, businesses are allowed to record cryptocurrency as a financial asset (financial instrument / intangible asset), so cryptocurrency can be used by businesses and individuals as an investment. In developed countries, where the legal framework for the operation of cryptocurrencies has been created, new derivative financial instruments are emerging: Bitcoin futures and options on Bitcoin futures. The purpose of the article is to study the features of derivative financial instruments for cryptocurrencies and prospects for their use in Ukraine. The authors analyzed the peculiarities of the functioning of Bitcoin derivatives on Chicago Mercantile Exchange (CME). It has been established that both Bitcoin futures and options on Bitcoin futures are settlement contracts without the actual delivery of the underlying asset, and their value is formed depending on the spot prices for bitcoin. According to the results of the study, it can be argued that derivatives based on cryptocurrencies (bitcoin) are used mainly for speculative purposes, are highly volatile and high risk, require significant investment to participate in trading (compared to derivatives on traditional financial instruments) and do not involve any transactions with direct cryptocurrencies. Domestic legislation does not explicitly prohibit investments in cryptocurrencies and financial instruments derived from them, but does not determine the legal status of cryptocurrencies. National financial market regulators do not provide any guidance on valuation, accounting and cryptocurrency transactions to businesses, but only warn of the high risks of investing in cryptocurrencies.

Authors:   Kyiv National Economic University named after Vadym Hetman, Kyiv, Ukraine, Rudenko Viktoriya
Published: November 2020

In market conditions, one of the main regulators of economic development is the financial mechanism, a key element of which is the fiscal mechanism for regulating the national economy investment development. Currently, the methods of the fiscal mechanism are not used effectively enough in Ukrainian practice, as evidenced by the low investment attractiveness of the economy and weak investment activity of economic entities. Therefore, the definition of the essence and components of methods of the fiscal mechanism is currently among the important financial and economic issues, the scientific substantiation of which largely depends on the economy investment development. The article is devoted to the study of theoretical approaches to the functioning of the methods of the financial mechanism and on this basis to determine the content and composition of the methods of the fiscal mechanism. It was determined that there are various approaches to understanding the essence of financial methods (as means, forms, methods, rules) and three conceptual approaches to the interpretation of the methods of financial mechanism: management (considers the methods of financial mechanism as processes in which implementation of financial policy); organizational (treats the methods of the financial mechanism as a means of organizing financial relations, which are formed in the process of implementing financial policy); complex (characterizes the methods of the financial mechanism as a process of organizing financial relations to achieve the objectives of financial policy). As a result of research of theoretical bases of functioning of financial methods the essence of methods of the fiscal mechanism of regulation of national economy investment development was substantiated. The main methods of the fiscal mechanism were identified, including planning, organization and control. The basic requirements to functioning of methods of the fiscal mechanism of regulation of the national economy investment development were considered.

The purpose of the study is to find out whether such variables as access to finance, human resource competence and information systems can improve the performance of small and medium-sized enterprises in Palembang (Indonesia). The authors use the foundations of the contingency theory and the theory of information systems (in particular, the Technology acceptance model (TAM)). To evaluate the impact of these three variables on the performance of small and medium-sized enterprises, the authors use organizational culture as a study moderator variable. The study is based on the use of descriptive statistics methods. The random sample of the study is 386 respondents. To process digital data, a computer program for statistical data processing, SPSS 20, was used. It was determined that access to finance has a decisive influence on the efficiency of performance of small and medium-sized enterprises. At the same time, organizational culture mitigates the impact of information systems and the human resource competence on the performance of small and medium-sized enterprises, which is also quite significant. The study results indicate an unsatisfactory level of relations between small and medium-sized enterprises, on the one hand, and the Office of Cooperatives, Small and Medium Enterprises in Trade and Industry of Palembang City, on the other. The authors believe that business entities should interact more actively with agencies that are responsible for the development of small and medium-sized enterprises. Through this interaction, small and medium-sized enterprises will be able to obtain more accurate information about their development potential and become the driving force behind the economic growth of Palembang City.

Published: November 2020

Crop and nutrient management options could improve the yield performances of late transplant Aman rice which is generally lower compared to optimum transplanting. To address these issues, an experiment was conducted at Bangladesh Agricultural University, Mymensingh to investigate the effect of spacing and nutrient management options on yield and yield components of late transplant Aman rice and to find out the better treatment combination to obtain higher yield. The experiment was laid out in two factors randomized complete block design (RCBD) with three replications consisting of three spacings viz. S1 =25 cm×15 cm , S2 =25 cm×10 cm and S3 =20 cm×10 cm; and eight nutrient management options viz. N0 = Control (No fertilizer), N1 = Poultry manure @ 5 t ha-1 , N2 = Vermicompost @ 3 t ha-1 , N3 = Researcher’s practice (Urea, TSP, MoP, Gypsum and ZnSO4 @ 180,75,105, 60 and 7.5 kg ha-1, respectively), N4 = 75% N3 + Poultry manure @ 2.5 t ha-1, N5 = 50% N3+ poultry manure @ 5 t ha-1, N6 = 75% N3+ Vermicompost @ 1.5 t ha-1 and N7 = 50% N3+ Vermicompost @ 3 t ha-1. Pre-germinated seeds of BRRI dhan46 were sown in wet nursery bed on 16 August and 30–d–old seedlings were transplanted as per treatments on 15 September in 2017. Yield and yield components were significantly influenced by spacing, nutrient management options and their interactions. The highest yield (5.20 t ha-1) was obtained the spacing 25 cm×10 cm which was at par with 25 cm×15 cm (5.12 t ha-1) and the lowest (4.88 t ha-1) was in 20 cm×10 cm. Statistically similar grain yield 5.85, 5.81 and 5.79 t ha-1 were produced in the treatments N3, N4 and N6, respectively. Grain yield increased in the treatments having combination of inorganic and organic nutrient, and also in the optimum inorganic fertilizers (researcher’s practice). The highest grain yield (5.98 t ha-1) was obtained in the interaction S2×N3 which was at par with S1 x N3, S1 x N4, S1 x N6, S2 x N4 and S2 x N6. Performances of sole organic fertilizers were not satisfactory level. Therefore, reduced amount (75%) of inorganic fertilizers combined with organic fertilizers (poultry manure 2.5 t ha-1 or vermicompost 1.5 t ha-1) along with closer spacing 25 cm×10 cm would be recommended to achieve better and sustainable yield performance of late transplant Aman rice cv. BRRI dhan46.

Published: November 2020

An experiment was carried out at the Research Field of Crop Physiology and Ecology Department, Hajee Mohammad Danesh Science and Technology University, Dinajpur from July to November 2018. The study evaluated the effects of poultry litter based composts on morpho-physiological, yield and yield contributing characters of transplanted aman rice (var.Binadhan-7, BRRI dhan56, BRRI dhan66) and soil fertility. The experiment was laid out in a two factorial complete randomized design (CRD) with three replications. Factor A included three varieties (Binadhan-7: V1, BRRI dhan56: V2, and BRRI dhan66: V3) and factor B comprised of three fertilization levels viz. control (inorganic)-F1, poultry litter based compost 20 ton ha-1: F2, and 30 ton ha-1: F3. The performances of plant growth parameters such as plant height, tiller number, leaf number, leaf area, SPAD value, as well as yield and yield contributing parameters, and soil chemical properties were measured. Varieties and fertilizer levels significantly influenced most of the morphophysiological traits and yield and yield contributing characters. The tallest plant was recorded from V2 variety (BRRI dhan56). The highest leaf number hill-1 (80.89 at 30 DAT) was recorded from V3 (BRRI dhan66). The highest number of tiller was produced by the interaction of compost F2 (20 t ha-1) with V1 (Binadhan-7). The highest effective tiller number (13.67) hill-1wasrecorded from F2 (compost 20 t ha-1) with F1 (Binadhan-7) at maturity. The longest panicle (24.16 cm) was found in F1V1 (inorganic with Binadhan-7) treatment. The highest 1000-grain weight (23.57 g) was recorded from F3V3 treatment (compost-30 t ha-1 with BRRI dhan66). The maximum harvest index was recorded from F1 (inorganic) with BRRI dhan66. Soil fertility status increased with higher dose poultry litter based compost (30 t ha-1).

Published: November 2020

The experiment was conducted at Multi Location Testing site under On-Farm Research Division, Bangladesh Agricultural Research Institute, Mymensingh 2016- 17 and 2017-18 to evaluate the agro-economic performance of improved cropping pattern for increasing cropping intensity, system productivity and profitability as compared to farmers’ existing cropping pattern. The experiment was laid out randomized complete block design with six dispersed replications. Two cropping pattern viz., improved cropping pattern Garden pea (var. BARI Motorshuti-3) - Boro (var. BRRI dhan28) - T. Aman rice (var. BRRI dhan32) and farmers’ existing pattern Fallow - Boro (BRRI dhan28) - T. Aman rice (var. BRRI dhan32) as control were tested. Improved cropping pattern produced higher mean rice equivalent yield (30.26 t ha-1 yr.-1), production efficiency (74 kg ha-1 day-1 ), land utilization index (72 %) and labour employment (382 man-days ha-1 yr.-1) than farmers’ pattern which were 200, 37, 35 and 55% higher over existing pattern. Average gross return (Tk.486430 ha-1), gross margin (Tk. 284787 ha-1) and marginal benefit cost ratio (4.60) of improved pattern indicate it’s superiority over farmers’ pattern. The fertility status of soil i.e. pH, organic matter, total N, available P, S, Zn and B content in soil were increased over the initial soil due to addition of garden pea biomass. Thus, inclusion of garden pea in the existing pattern would improve soil health and system productivity as a whole. Experimental findings revealed that there is potential for greater adoption of intensified cropping systems with increased productivity and profitability as compared to rice–rice systems in Mymensingh region.

Authors: Shome S , Biswas PK , Ullah MJ , Barman A
Published: November 2020

Quality is one of the key characteristics of rice and is largely governed by nitrogen application. An experiment was conducted to scrutinize the effect of nitrogen on quality characteristics of rice, with three nitrogen levels (viz. 50 kg N ha-1, 100 kg N ha-1 and 150 kg N ha-1) and four varieties/lines (viz. SAU ADL1, BRRI dhan70, BRRI hybrid dhan6 and SAU ADL11). Results revealed that quality characters of transplanted Aman rice were significantly influenced by nitrogen, variety and their interaction. Increasing trend was observed with the increasing level of nitrogen from 50 to 150 kg ha-1 regarding hulling percentage and milling outturn while decreasing trend was observed in case of apparent amylose content and imbibition ratio. Maximum protein content (9.60%) and gel consistency (96.16 mm) were recorded at 100 kg N ha-1. Among the studied materials, SAU ADL11 performed better in case of all studied parameters. Although interaction of 150 kg N ha-1 with SAU ADL1 and SAU ADL11 gave maximum value of hulling percentage and milling outturn. In interaction of 100 kg N ha-1 with these two lines gave maximum protein, gel consistency and satisfactory levels of all quality characters. So, it can be suggested to carry out further investigation with these two rice lines having 100 kg N ha-1.

O-9897) cultivation. Two herbicide treatments, such as; W1 = Fenoxaprop-p-ethyl (Whip Super 9 EC) and W2 = Ethoxysulfuron (Sunrice ® 150WG) were tested. There were 14 treatments. T1- T6 treatments did not include hand weeding which was done 20 days after the herbicide spray [T1 = 100% recommended doses (RD) of both W1and W2 where W2 was sprayed one day after that of W1, T 2 = 50% dose both of W1and W2 where W2 was sprayed one day after that of W1, T3 = 100% dose of both W1 and W2 where both of the herbicide mixed together and sprayed on the same day, T4 = 50% dose of both W1 and W2 where mixture of both were sprayed on the same day, T5 = only 100% dose of W1, T6 = only 100% dose of W2]. The treatments T7 - T12 included one had weeding following the application of herbicides [T7 = 100% dose both of W1 and W2 where W2 was sprayed 1 day after that of W1, T8 = 50% dose both of W1 and W2 where W2 was sprayed 1 day after of W1, T9 = 100% dose both of W1 and W2 were mixed and sprayed together on the same day, T10 = 50% dose both of W1 and W2 mixed together and sprayed same day, T11 = only 100% dose of W1, T12 = only 100% dose of W2]. The treatments T13 and T14 did not include herbicide application [T13 = Two hand weeding (20-25 and 45-50 DAS) and T14 = control with no herbicide application]. The experiment was laid out in RCBD with three replications. Results revealed that Khudesama (Echinochloa colonum) and Angulighash (Digitaria sanguinalis), Khudesama and Mutha (Cyperus rotundus) were best controlled by herbicide application. T3 gave highest fibre yield of 1.89 tha-1 when W1 and W2 sprayed at the same day with 100% RD. In case of one weeding 20 days after spray fibre yield and stick yield were differed significantly as compared to those of control at Manikganj. Treatment T7 gave highest fibre yield (3.11 t ha-1) when W2 sprayed after 1 day of W1 with 100% RD. At Faridpur, T3 gave the highest fibre yield (2.68 t ha-1) when W1 and W2 sprayed at the same day with 100% RD. Incase of one weeding 20 days after spray, T7 gave highest fiber yield (2.79 t ha-1) when W2 was sprayed 1 day after that of W1 with 100% RD.

There is a chaotic scenario that exists in the field of prostate cancer (PCa) screening. To balance goals, such as decreasing mortality, avoiding unnecessary procedures, and decreasing the cost of medical care, the pendulum seems to have swung to the side of more restricted screening. The decrease in PCa screening has led to a slowly creeping decline in the favourable outcomes that existed among patients with PCa. If a potential patient or a family member is trying to get clear guidance about PCa screening by searching the internet, they will end up confused by several recommendations from many organisations. It is even more challenging to obtain any clarity about PCa screening for special populations, such as those with a family history of PCa, those of African descent/African Americans, and the elderly. The advent of genomic medicine and precision medicine is an opportunity to identify those at a very high risk of developing aggressive PCa, so that PCa screening can be more actively undertaken among them. In this paper, the authors review the current recommendations by different entities and summarise emerging molecular markers that may help bring clarity to PCa screening. The authors predict that concrete, consensual guidelines will emerge in less than one decade. Meanwhile, this article suggests intermediary steps that will help save lives from PCa mortality, especially for under-represented populations. This paper is a catalyst to stimulate further discussion and serves as a guide to noncancer-specialists for the near future as precision medicine progresses to better understand risk–benefit and cost–benefit ratios in PCa screening.
Mise en Esprit: One-Character Films and the Evocation of Sensory Imagination
Authors: Hanich Julian
Published: November 2020

This article starts out by introducing the category of the ‘one-character film’ — that is, narrative feature films that rely on a single onscreen character. One-character films can range from extremely laconic movies entirely focused on the action in the narrative here-and-now via highly talkative films that revolve around soliloquies of self-reflection, questioning of identity and a problematizing of the narrative past to strongly dialogue-heavy films that — via phones and other telecommunication devices — reach far beyond the depicted scene. It is on the latter that the article eventually focuses. Films like Buried (2010), Locke (2013) or The Guilty (2018) centrifugally thrust the viewers into a simultaneous present that remains invisible and that they have to imagine in sensory ways. Imagining this invisible elsewhere, which I call mise en esprit, can be facilitated and evoked through various cinematic means such as reduced within-modality-interference, suggestive verbalizations, acousmatic voices and sound effects.
Imagining Cinema: ‘Cinempathy’ and the Embodied Imagination
Authors: Sinnerbrink Robert
Published: November 2020

Imagination has been the focus of much philosophical inquiry in recent decades. Although it plays an essential role in linking emotional engagement with ethical experience, imagination has received comparatively little attention in film-philosophy. In this article, I argue that imagination plays an essential role in linking emotional engagement with moral-ethical experience. Drawing on phenomenological, cognitive and aesthetic perspectives, I focus on perceptual imagining and suggest that an account of embodied cinematic imagination — encompassing both perceptual/sensory and propositional/cognitive imagining — is especially relevant to theorizing cinematic experience. The interplay of first-person empathic and third-person sympathetic perspectives (‘cinempathy’) is another essential feature of our emotional and ethical engagement with cinema. By synthesizing ‘bottom-up’ sensory, affective responses to audiovisual images, with ‘top-down’ cognitive processes associated with mental simulation, an account of embodied cinematic imagination can explain how emotional engagement and ethical responsiveness work together in our experience of audiovisual narratives.
Charles Dickens: The Woolf Afterlife
Authors: Hollington Michael
Published: November 2020

This essay begins with a survey of attitudes towards Charles Dickens in the extended Stephen family, as these were inherited by the modernist writer Virginia Woolf. On the one hand, there is the strongly negative view of her Uncle Fitzy (Sir James Fitzjames Stephen), and the lukewarm, rather condescending opinion of her father Leslie Stephen. On the other, there is the legacy of enthusiastic attention and appropriation from William Makepeace Thackeray's two daughters – her aunt Anne Thackeray Ritchie and (posthumously) Min, Leslie Stephen's first wife.

In the second section I survey Woolf's critical writings on Dickens, adding a glance at the opinions of her husband Leonard. In both, there is an evolution towards greater attention and enthusiasm. Besides Woolf's familiar essay on David Copperfield (1849–50), I give prominence to lesser-known writings, in particular to her laudatory assessment and analysis of Bleak House (1852–3).

The third and final part concerns signs of the influence of Dickens in Woolf's first novel, The Voyage Out (1915). The earlier, satiric part of the novel shows the impact both of Jane Austen and Dickens as ironists and humourists. During the tragic conclusion, influenced by a reading of Fyodor Dostoevsky, Jane Austen drops out, but Dickens is retained.
Dickens's Afterlife: Character and Cultural Memory
Authors: England Maureen
Published: November 2020

As a post-mortem of Dickens, this paper will examine Dickensian afterlives in modern multimedia representations of Dickens and his characters. I will consider these representations and modern popular culture's representational balance between the writer and his works. The three recent examples of Dickens and his characters in different media – small screen, video game, and cinema – that will be discussed are: the 2015 BBC series Dickensian; the ‘Darwin and Dickens Conspiracy’ additional downloadable content (DLC) of the 2015 video game Assassin's Creed: Syndicate; and the 2017 film The Man Who Invented Christmas. These modern appropriations of Dickens illustrate how Dickens's characters persist in cultural memory, and indeed how Dickens himself has become a recognisable character. I will examine how these adaptations are rooted not in familiarity with the original texts, but in a shared cultural memory of Dickens and his characters. Ultimately, these Dickensian afterlives show that Dickens and his characters can be used in popular culture as a pseudo-authentication of the Victorian and as a memorial of Dickens himself.
Scanning Electron Microscopy Reveals the Antennal Micromorphology of Lamprodila (Palmar) festiva (Coleoptera: Buprestidae), an Invasive Pest of Ornamental Cupressaceae in Western Palaearctic

Published: November 2020

The Cypress jewel beetle, Lamprodila (Palmar) festiva festiva (Linnaeus, 1767), is a serious invasive pest of ornamental Cupressaceae, which has recently expanded its range from the Mediterranean region northwards to central and eastern Europe, and to the Russian Black Sea coast. In this study, we conducted a scanning electron microscopy study of the micromorphology of the male and female antennae of L. festiva to examine the morphology, numbers, distribution, and possible functions of antennal sensilla. Most sensilla are located in the sensory fields within the apical depressions on antennomeres IV–XI. We identified four main types of antennal sensilla in L. festiva: sensilla chaetica (seven subtypes, of which two occur only in females), sensilla basiconica (five subtypes), multiporous grooved pegs (two subtypes), and Böhm sensilla. Females have relatively more sensilla chaetica and multiporous grooved pegs, whereas males have more sensilla basiconica. We discuss possible functions of all examined sensilla and compare them with those in other Buprestidae or other insects. Our study should serve as background information for advanced electrophysiological and behavioral experiments to better understand the functions of different sensilla and mechanisms related to semiochemically based pest control strategies.
Estimation of Active Compounds Quantity from Pharmaceuticals Based on Ginkgo biloba
Authors: Gunache (Roșca) Ramona Oana , Apetrei Constantin
Published: November 2020

Ginkgo biloba is one of the most important sources of active compounds, mainly flavonoids and phenolic compounds. Due to its importance related to pharmaceutical practice, the making of a qualitative and quantitative method for the detection and quantification of active compounds from Ginkgo biloba pharmaceutical products is desirable. In this study, the content of biological active compounds from Ginkgo biloba products was estimated using cyclic voltammetry. The electrochemical determination of active compounds was carried out by using a screen-printed carbon electrode modified with carbon nanotubes. The studies regarding parameter optimization were made using solutions containing potassium ferrocyanide and catechol, respectively. In both cases, the redox processes of studied compounds was observed, which were controlled by the diffusion phenomenon. We analyzed two pharmaceutical products containing Ginkgo biloba, a RX product (recipe medicine requires a medical prescription to be dispensed) and an OTC (Over-The-Counter, which can be obtained without a prescription) product. The cyclic voltammograms of the two products showed two redox processes due to the antioxidant properties of the products. It was found that the RX product had a greater content of active compounds compared to the OTC product. Therefore, the voltammetric method has great utility for the determination of compounds with redox properties from pharmaceutical products containing Ginkgo biloba.
Effective Simulations of Electronic Transport in 2D Structures Based on Semiconductor Superlattice Infinite Model
Authors: Mączka Mariusz
Published: November 2020

Effective simulations of semiconductor superlattices are presented in the paper. The simulations have been based on the Wannier function method approach where a new algorithm, inspired by Büttiker probes, has been incorporated into determining the Green function procedure. The program is of a modular structure, and its modules can either work independently, or interact with each other following a predefined algorithm. Such structuring not only accelerates simulations and makes the transport parameters possible to initially assess, but also enables accurate analysis of quantum phenomena occurring in semiconductor superlattices. In this paper, the capabilities of type I superlattice simulator, developed earlier, are presented, with particular emphasis on the new block where the Fermi levels are determined by applying Büttiker probes. The algorithms and methods used in the program are briefly described in the further chapters of our work, where we also provide graphics illustrating the results obtained for the simulated structures known from the literature.
Application of Perovskite Layer to Rotor for Enhanced Stator-Rotor Capacitance for PMSM Shaft Voltage Reduction
Authors: Aqil Muhammad , Im Jun-Hyuk , Hur Jin
Published: November 2020

Adjustable speed drives use Pulse Width Modulation (PWM) to switch DC-bus voltage for the synthesis of three-phase voltages to provide power to the permanent magnet synchronous motor (PMSM). This switching action produces very short rise and fall times and Common Mode Voltage (CMV) in the motor winding, exciting the parasitic capacitances inherent to the motor geometry. These parasitic capacitances give rise to shaft voltage due to a voltage divider action. Therefore, in this paper, first, motor parasitic capacitances and voltage divider action is explained. Second, the Barium Titanate (BTO) layer is coated onto the rotor to enhance stator-to-rotor compound capacitance and a simulation is performed showing the dependence of the shaft voltage on the permittivity of the perovskite (BTO) layer. The rotor BTO layer reduces the bearing voltage ratio as well. Third, experimental results are presented showing effectiveness of the application of the BTO layer to rotor and reduction of shaft voltage of the motor in anticipation to mitigate the damaging electric discharge machining (EDM) bearing currents. Likewise, the experiment shows that the magnetic design of the motor is not affected by the BTO layer to rotor.
“Fast Track” Analysis of Small Wind Turbine Blade Performance
Authors: Stępień Małgorzata , Kulak Michał , Jóźwik Krzysztof
Published: November 2020

Small wind turbines (SWTs) can be significantly sensitive to variances in the blade geometry shape when their operation in relatively low ranges of Reynolds numbers is considered. An SWT case study, where an existing wind turbine prototype was equipped with a redesigned blade set, to increase its aerodynamic efficiency, is presented. The geometry modification process was targeted at maximizing the turbine power coefficient in the presumed point of low Reynolds operation. The applied design and analysis methods included practical implementation of previously established “Fast Track” procedure for wind turbine development. A newly prepared blade geometry and a reference blade set were examined numerically and experimentally. Selected design and assessment processes were supposed to be low resource demanding, making them possibly highly applicable in renewable energy industry. Therefore, the numerical analysis of both geometries was based on BEM (blade element momentum theory) equations. The research was expanded by model validation in small-scale wind tunnel tests to provide detailed information on BEM data reliability in comparison to the results of the experiment. The small-scale analysis, performed in Reynolds numbers below 100,000, provided information sufficient for evaluation of the redesigned blade. Implementation of the geometry obtained throughout the proposed procedure increased the rotor’s maximum power coefficient by 10%.
Dementia Literacy and Willingness to Dementia Screening
Authors: Aihara Yoko , Maeda Kiyoshi
Published: November 2020

The increasing prevalence of delayed and missed diagnoses for dementia constitutes major public concern. In this regard, inadequate knowledge and poor understanding of the condition may create a barrier to timely dementia screening. This cross-sectional study assessed dementia literacy, then identified the association between dementia literacy and willingness to undergo routine dementia screening among community-dwelling older adults in two urban areas of Japan. More specifically, structured questionnaires were distributed to a total of 854 individuals aged ≥ 65 years. A multivariate logistic regression was then used to explore the factors associated with dementia literacy and willingness to undergo routine dementia screening. Results showed that younger respondents and respondents who received dementia information from television/radio and/or paper-based sources were more likely to have high dementia literacy. While less than half of participants were willing to undergo routine dementia screening, those with higher dementia literacy were more willing to do so (albeit, not a statistically significant difference). Although there are pros and cons to routine dementia screening, it is necessary to implement such a system to detect dementia and cognitive impairment. Further, assessments should also attempt to gain information about individual beliefs and understandings related to dementia information.
Preliminary Assessment of Chemical Elements in Sediments and Larvae of Gomphidae (Odonata) from the Blyde River of the Olifants River System, South Africa

Published: November 2020

Benthic macroinvertebrates and sediments can act as good indicators of environmental quality. The aim of this study was to assess the accumulation of chemical elements in the Gomphidae (Odonata) collected in the Blyde River. Seven sites were sampled for river sediments assessment and five sites for larvae (naiads) of Gomphidae bioaccumulation analysis. The tissue samples were analysed using inductively coupled plasma optical emission spectrometry (ICP-OES). The results showed high levels of all of the tested elements except Cd in the sediment. The mean concentrations of As, Cu and Cr exceeded the standard guideline values, whereas Pb and Zn were below the standard guideline values. In the insect body tissue, the concentrations of most elements were higher than in the sediments. The elements with the highest concentrations were Mn, Zn, Cu, and As. The bioaccumulation factor (BF) showed a tendency for bioaccumulation for almost all of the selected elements in the insect. The BF value was high for Cu, Mn, Sb, and Zn (BF > 1). The high concentrations of elements in the insect body tissue may pose a risk to fish that consume them, and subsequently to humans when fish from the river are consumed. It is therefore important to monitor the river to reduce pollution to prevent health risks in humans, especially in communities that rely on the river for water and food.
