Fast calculation of high-definition depth-added computer-generated holographic stereogram by spectrum-domain look-up table [Invited]
Authors: Liu Jung-Ping , Lu Sung-Lin
Published: October 2020

High-definition depth-added computer-generated holographic stereogram (DA-CGHS) is superior in its high quality, easy realization, and auto-shading effect. However, its computing cost is extremely high because numerous scenes together with depth information must be calculated. Here, we proposed a fast calculation scheme of DA-CGHS by the spectrum-domain look-up table (SDLUT) method. In SDLUT, diffraction fields on the hogel plane of selected reference points in the object space are calculated. Subsequently, the fields are Fourier transformed to the spectrum domain. Because the signal energy always concentrates in a small spectrum region, these regions are cropped as the elemental tables. In the computing of the hogels, the field superposition is conducted in the spectrum domain by using the elemental tables. In our demonstration, the table size of SDLUT is only 0.44% that of the look-up table (LUT). Because the table size is very small, the computing time of SDLUT method can be nearly 80 times faster than that of conventional LUTs in the spatial domain, while the image quality is comparable.

Published: October 2020

The objective of this work was to evaluate physiological and biochemical responses of Pele de sapo melon to different irrigation depths (ID) and bioestimulant rates (BTM) to improve its production efficiency. The experiment was conducted in an experimental field in Juazeiro, BA, Brazil. A randomized block design in split split-plot arrangement was used, with four ID (60, 80, 100, and 120% of crop evapotranspiration – ETc) in the plots; five (BTM) (Stimulate® at 0, 0.6, 1.2, 2.4, and 4.8 L ha-1 applied via irrigation system during the flowering stage and after the fruiting stage) in the subplots; and two crop seasons (hot season, 23 to 39 °C; and cold season, 15 to 30 °C) in the sub-subplots. The plants were under daily drip irrigation and spacing of 2.0 × 0.3 m. The variables evaluated were: gas exchange, water use efficiency, chlorophyll a and b, relative water, sugar, and amino acid contents, and fruit yield. The results showed that the ID of 60% ETc resulted in water deficit, denoted by increases in solute concentrations, whereas the ID of 80% and 100% resulted in plants with good performance for biochemical, physiological, and production parameters in both crop seasons. The hot season, ID of 120% ETc, and BTM of 2.4 L ha-1 are recommended for Pele de sapo melon crops, since they result in the best physiological responses and fruit yields.
Light quality on growth and phenolic compounds accumulation in Moringa oleifera L. grown in vitro
Authors: Da Silva Raphael Reis , Ribeiro de Souza Rafaela , Coimbra Mairon , Nery Fernanda , Alvarenga Amauri , Paiva Renato
Published: October 2020

All plant parts of the Moringa oleifera can contain relevant concentrations of phytochemicals with health benefits. Plants grown in vitro allow pathogen-free plant material production and rapid propagation, and this technique is widely used to obtain secondary metabolites. This study analyzed how light spectrum quality affects growth, chlorophyll, and total phenolic content in M. oleifera plants grown in vitro. M. oleifera seeds were inoculated in MS medium supplemented with 3% sucrose and 0.7% agar and were stored under a controlled temperature, humidity and photoperiod. The light conditions tested were white fluorescent lamps (WFL) and light-emitting diodes (LED: 70% red + 30% blue), both standardized with a photon flux density of 58 μmol m-2s-1. Radiation emitted by WFL and LED did not influence stem germination, height, or diameter. However, WFL provided higher total chlorophyll levels. All plant parts germinated in vitro were analyzed via high-performance liquid chromatography with a diode-array detector (HPLC-DAD), and preliminary analyses revealed preferential synthesis of gallic acid derivatives in the leaves under LED radiation. For the total phenolic content, leaves under the LED and WFL irradiations showed 3.524 ± 0.054 and 3.805 ± 0.304 micrograms, respectively, of gallic acid equivalents per milligram of dry matter (μg GAE mg-1 DM). Light quality did not interfere with phenolic compound accumulation; however, it stimulated the preferential synthesis of gallic acid derivatives in leaves grown under LED radiation, and the evidence indicated that all evaluated organs synthesized nonpolar substances.

Published: October 2020

This research aimed to evaluate the effect of doses of organic compost on the yield and economic profitability of organic yellow passion fruit grown in sandy-loam and clay-loam soils. Two experiments were installed in the field, in different soil types and municipalities in the state of Acre. The experimental design was in randomized blocks with five treatments, four replications, and four plants per experimental unit. The treatments consisted of adding the compost as a replacement for 1/3 of the volume of cylindrical planting holes with 40 cm, 80 cm, 120 cm, 160 cm, and 200 cm, corresponding to the addition of 6.3; 25.1; 56.5; 100.4, and 156.9 liters per planting hole, respectively. The mean fruit mass and the yield of the yellow passion fruit were higher in sandy-loam soil. The total revenue was R$ 4,311.6 ha-1 in the clayey soil and R$ 5,841.9 ha-1 in the sandy soil. The total cost was higher in the clayey soil than in sandy soil. Both soils responded in quadratic function with an increase in the cost as the volume of organic compost was increased, ranging from R$ 12,736.00 ha-1 with 6.3 liters of compost per hole up to R$ 26,249.63 ha-1 with 156.9 liters of compost per hole. Net income was negative for all compost volumes in both types of soil, responding linearly, with a reduction in revenue of R$ 80.82 ha-1 with the addition of each liter of compost in the pit due to the low yield caused by period long drought.

Published: October 2020

The mango and cajarana are pleasant-tasting fruits, yellow in color, have ascorbic acid with antioxidant properties that slow down oxidation and help the immune system to promote well-being. The production of blends can improve nutritional and sensory characteristics, combining macro and micronutrients that may be present in a higher concentration in one fruit and deficient in another, increasing the possibility of obtaining new flavors constituting a new product. The study had as objective the elaboration of blends of mango cv. espada and cajarana and to determine the physical-chemical characteristics and color parameters. Three formulations were prepared: F1 - 50% mango pulp and 50% cajarana pulp; F2 - 90% mango pulp and 10% cajarana pulp and F3 - 10% mango pulp and 90% cajarana pulp. The formulations were evaluated for physicochemical parameters of water activity, moisture content, ash, total soluble solids, pH, total titratable acidity, ascorbic acid, proteins, lipids, total sugars, reducers, non-reducers and color parameters. The data obtained were submitted to analysis of variance and comparison between means by the Tukey test. The blends caused significant changes in most of the parameters evaluated, with an increase in the moisture content, ash, total titratable acidity, proteins and lipids as the concentration of the cajarana pulp was increased. The increase in the proportion of mango pulp favored the achievement of lighter blends, with a predominance of yellowness. However, the development of blends from this study presents itself as a viable alternative for the use of fruit pulps, both in terms of nutrition, complementing the nutrient content through this mixture as a very promising product for the market.

Published: October 2020

O câncer de próstata é a neoplasia maligna de maior incidência entre os homens no Brasil.  No curso da doença, surgem diversas possibilidades clínicas, levando à necessidade de internações hospitalares. ­ O objetivo deste trabalho é caracterizar as internações por câncer de próstata (CAP) na 1a Regional de Saúde do estado de Pernambuco, no período de 2012 a 2016.  Foi realizado um estudo epidemiológico do tipo quantitativo descritivo de caráter transversal. Os dados são do tipo secundário, coletados a partir do Sistema de Informação Hospitalar – SIH, através da interface de consulta Tabnet/PE. A população estudada foram todos os homens que se internaram por CAP na 1a Regional de Saúde de Pernambuco, no período de estudo. Entre 2012 e 2016, ocorreram 3.985 internações por CAP. Homens pardos (44,6%) e faixa etária de 50 a 79 anos (85%) foram os que mais internaram. A 1a Regional de Saúde foi responsável pela maior quantidade de internação (70,5%). A taxa de mortalidade no período foi de 8,5 (395 mortes). O valor total gasto foi de R$ 8.569.339,80 e o valor médio de internação foi de R$ 2.175,51. O Hospital do Câncer de Pernambuco – HCP e o Instituto Materno Infantil de Pernambuco – IMIP são os estabelecimentos que mais internaram pacientes no período (54,2%) juntos. A quantidade de internação e de óbitos se encontram em tendência de crescimento, assim como os gastos anuais. A busca tardia pelo diagnóstico e pelo tratamento são possíveis causas dessa elevação e pode ainda mais agravar esses números, se não houver nenhuma intervenção maior e mais institucionalizada em relação a prevenção do câncer de próstata no Estado.

Archive Fever and British Romanticism: Blake, Byron, and Keats
Authors: Kerler David
Published: October 2020

The article explores the interrelation of archives, melancholia, and their (de)constructive features in British Romantic poetry. It will argue that the proliferation of archives and archival practices from the late eighteenth century on had a strong influence on the literary‑cultural output of the British Romantics.This shall be scrutinised by drawing on an extended reading of Jacques Derrida’s “Archive Fever” (1995) and Julia Kristeva’sBlack Sun,focusing on two basal, closely related aspects: (1) the subject’s feverish desire to archive, and (2) the archive’s (self‑)destructive tendencies. A close reading of paradigmatic writers and their poems (William Blake, Lord Byron, and John Keats) shall illustrate that the notion of “archive fever” turns out to be especially determinant for Romantic subjectivity, aesthetics, and itssujets.
The Document as Epistemic Object: Notes on Archival Knowledge Cultures
Authors: Starre Alexander
Published: October 2020

This article strategically resituates scholarly engagement with archival documents within the media ecology and the epistemic culture that sustains literary and cultural studies, noting affinities between historical and contemporary configurations as well as between theoretical and medial-material dimensions of archives. Based on current debates on the growing relevance of archival documents in American Studies and adjacent fields, it stakes out a framework that leans on recent work in a small branch of contemporary literary theory focused on historical epistemology, especially with regard to the notion of ‘epistemic objects’. Engaging these theoretical concerns, the article discusses concrete archival collections and documents, including letters by the novelist Willa Cather and items from a capacious archive documenting the emergence and evolution of Andrew Carnegie’s public library philanthropy. I outline several ways in which the shape and the aesthetics of such archives embody the information economies and epistemic situations of the past – in this case, the formative period around 1900. Finally, the article addresses the digital document overload that confronts the contemporary researcher and comments on the emerging archival knowledge culture of today’s humanities.

Objectives

Plasma free metanephrines are commonly used for diagnosis of pheochromocytoma and paraganglioma (PPGLs), but can also provide other information. This multicenter study prospectively examined whether tumor size, location, and mutations could be predicted by these metabolites.

Methods

Predictions of tumor location, size, and mutation type, based on measurements of plasma normetanephrine, metanephrine, and methoxytyramine were made without knowledge of disease in 267 patients subsequently determined to have PPGLs.

Results

Predictions of adrenal vs. extra-adrenal locations according to increased plasma concentrations of metanephrine and methoxytyramine were correct in 93 and 97% of the respective 136 and 33 patients in who these predictions were possible. Predicted mean tumor diameters correlated positively (p<0.0001) with measured diameters; predictions agreed well for pheochromocytomas but were overestimated for paragangliomas. Considering only patients with mutations, 51 of the 54 (94%) patients with NF1 or RET mutations were correctly predicted with those mutations according to increased plasma metanephrine, whereas no or minimal increase in metanephrine correctly predicted all 71 patients with either VHL or SDHx mutations; furthermore, among the latter group increases in methoxytyramine correctly predicted SDHx mutations in 93% of the 29 cases for this specific prediction.

Conclusions

Extents and patterns of increased plasma O-methylated catecholamine metabolites among patients with PPGLs allow predictions of tumor size, adrenal vs. extra-adrenal locations and general types of mutations. Predictions of tumor location are, however, only possible for patients with clearly increased plasma methoxytyramine or metanephrine. Where possible or clinically relevant the predictions are potentially useful for subsequent clinical decision-making.
Dependence uncertainty bounds for the energy score and the multivariate Gini mean difference
Authors: Bernard Carole , Müller Alfred
Published: October 2020

The energy distance and energy scores became important tools in multivariate statistics and multivariate probabilistic forecasting in recent years. They are both based on the expected distance of two independent samples. In this paper we study dependence uncertainty bounds for these quantities under the assumption that we know the marginals but do not know the dependence structure. We find some interesting sharp analytic bounds, where one of them is obtained for an unusual spherically symmetric copula. These results should help to better understand the sensitivity of these measures to misspecifications in the copula.
Das Ende des weströmischen Kaisertums – ein Ereignis der chinesischen Geschichte? Auswirkungen von Mobilität in eurasischer Perspektive
Authors: Meier Mischa
Published: October 2020

In dem Beitrag wird versucht, Geschehnisse der spätrömischen Geschichte im 5./6. Jahrhundert n. Chr. stärker in einen eurasischen Verflechtungszusammenhang einzubetten. Am konkreten Beispiel des Untergangs des Attila-Reiches (453) wird nach regionalen und weiträumigen Konsequenzen politischer Großereignisse gefragt. Dabei wird aufgezeigt, wie es nach dem Ende der hunnischen Machtbildung zunächst im Donauraum zu gravierenden ethnisch-politischen Neukompositionsprozessen kam (in die Ostrom immerhin noch gestaltend eingreifen konnte). Gleichzeitig lässt sich eine beträchtlicher Kriegerdrift nach Westen nachweisen, die den Untergang des weströmischen Kaisertums beschleunigt haben dürfte. Da ein größerer Teil ehemals unter hunnischer Kontrolle stehender Kriegerverbände sich zudem in den nordpontisch-kaukasischen Raum bewegte, kam es auch dort zu Unruhen. Diese wirkten sich direkt auf das Sāsānidenreich aus, das insbesondere in Armenien Aufstände und Unruhen zu gewärtigen hatte, die durch den Druck herandrängender Krieger aus den Kaukasusgebieten verschärft wurden. Sie zwangen die persischen Großkönige mehrfach in Zweifrontenkriege, da gleichzeitig an der Nordostflanke des Reiches Kidariten und vor allem Hephthaliten herandrängten. Die katastrophale Niederlage des Perozes 484 gegen die Hephthaliten ist in diesem geopolitischen Zusammenhang zu sehen; sie war keineswegs Folge eines unüberlegten militärischen Abenteuers, sondern sollte offenbar Zusammenschlüsse nordpontischer, ehemals hunnischer Kriegergruppen mit den Hephthaliten verhindern. Nach der Niederlage verloren die Sāsāniden jedoch für mehrere Jahrzehnte ihre Vormachtstellung in Zentralasien an die Hephthaliten, die sich Sogdiens und der dortigen Handelsnetzwerke bemächtigten, dadurch den Seidenstraßenhandel kontrollierten und in der Folge auch verstärkt mit den nordchinesischen Herrscherhöfen interagierten, die möglicherweise das türkisch-sāsānidische Bündnis, dem das Hephthalitenreich 560 nicht mehr standzuhalten vermochte, unterstützten.
Die Suche nach Ethnographica und die kunstsinnigen Kannibalen der Südsee. Oder: Was die koloniale Nostalgie im Kaiserreich mit der kolonialen
Aphasie heute zu tun hat
Authors: Habermas Rebekka
Published: October 2020

Im Mittelpunkt des Beitrags steht die Frage, wie die überraschend aktuell anmutenden Klagen darüber, dass viele Ethnographica in den Kolonien verloren gingen und ganze Völker im der außereuropäischen Welt aussterben würden, die von Ethnologen aber auch Malern wie Emil Nolde um 1900 allenthalben erhoben wurden, zu verstehen sind und welche Folgen sie zeitigten. Argumentiert wird, dass es sich dabei um eine Form von „kolonialer Nostalgie“ (Renato Rosaldo) handelte, welche als Teil der europäischen Krise der Moderne um 1900 gesehen werden kann. Ein Effekt dieser umfassenden Nostalgie war die Entstehung eines Ethnographica- und Naturaliamarktes, welcher wiederum auf kolonialen Strukturen basierte und diese auch stärkte. Gleichzeitig waren es aber just diese Sammelleidenschaft und die damit verbundene Vorstellung der Rettung von vermeintlich Urtümlichem, die Pate standen bei der Entstehung der modernen Malerei. Emil Nolde und andere moderne Maler/innen sammelten Ethnographica und integrierten deren Motive in ihre Bilder. Diese spezifische Rezeption des Außereuropäischen kann aber genauso wenig wie die Untergangsklagen im Sinne einer Kolonialkritik verstanden werden. Vielmehr trug die Art, wie das Außereuropäische von der sich formierenden modernen Malerei rezipiert wurde, auf geradezu paradoxe Art und Weise zu der heute in der Restitutionsdebatte allenthalben beklagten kolonialen Aphasie bei.
Modulation of sleep using electrical vestibular nerve stimulation prior to sleep onset: a pilot study
Authors: Goothy Sai Sailesh Kumar , McKeown Jason
Published: October 2020

Objectives

Electrical stimulation of the vestibular system (VeNS) has been shown to improve Insomnia Severity Index (ISI) when delivered during sleep. We hypothesize that repeated electrical vestibular stimulation, when delivered prior to sleep onset, will improve ISI scores. The primary aim of this study was to assess the effect that VeNS had on ISI scores when delivered prior to sleep onset. A secondary aim was to provide initial data indicating “length of time to effect” that will allow more appropriate design of a larger randomized control trial (RCT).

Methods

The present study was an experimental study (pre and post without control). The participants acted as self-controls. After recording the baseline values, electrical vestibular nerve stimulation was administered as intervention once in a day for 30 min, 1 h prior to sleep onset using ML1000 device (Neurovalens, UK) for 14 days.

Results

There was significant decrease in the ISI scores followed by the electrical vestibular nerve stimulation. Further, participants reported a significant increase in well-rested sleep post the intervention period.

Conclusions

This study supports our hypothesis that VeNS has a positive impact on ISI scores when delivered on a regular basis prior to sleep onset.
Testis and blood-testis barrier in Covid-19 infestation: role of angiotensin-converting enzyme 2 in male infertility

Published: October 2020

Severe acute respiratory syndrome coronavirus 2 (SARS- CoV-2) that causes COVID-19 infections penetrates body cells by binding to angiotensin-converting enzyme-2 (ACE2) receptors. Evidence shows that SARS-CoV-2 can also affect the urogenital tract. Hence, it should be given serious attention when treating COVID-19-infected male patients of reproductive age group. Other viruses like HIV, mumps, papilloma and Epstein–Barr can induce viral orchitis, germ cell apoptosis, inflammation and germ cell destruction with attending infertility and tumors. The blood-testis barrier (BTB) and blood-epididymis barrier (BEB) are essential physical barricades in the male reproductive tract located between the blood vessel and seminiferous tubules in the testes. Despite the significant role of these barriers in male reproductive function, studies have shown that a wide range of viruses can still penetrate the barriers and induce testicular dysfunctions. Therefore, this mini-review highlights the role of ACE2 receptors in promoting SARS-CoV-2-induced blood-testis/epididymal barrier infiltration and testicular dysfunction.
Data Anonymization through Collaborative Multi-view Microaggregation
Authors: Zouinina Sarah , Bennani Younès , Rogovschi Nicoleta , Lyhyaoui Abdelouahid
Published: October 2020

The interest in data anonymization is exponentially growing, motivated by the will of the governments to open their data. The main challenge of data anonymization is to find a balance between data utility and the amount of disclosure risk. One of the most known frameworks of data anonymization isk-anonymity, this method assumes that a dataset is anonymous if and only if for each element of the dataset, there exist at leastk− 1 elements identical to it. In this paper, we propose two techniques to achievek-anonymity through microaggregation:k-CMVM and Constrained-CMVM. Both, use topological collaborative clustering to obtaink-anonymous data. The first one determines theklevels automatically and the second defines it by exploration. We also improved the results of these two approaches by using pLVQ2 as a weighted vector quantization method. The four methods proposed were proven to be efficient using two data utility measures, the separability utility and the structural utility. The experimental results have shown a very promising performance.

Direct contribution of angiogenic factors to neurodevelopment: a focus on angiopoietins
Authors: Luck Robert , Karakatsani Andromachi , Ruiz de Almodovar Carmen
Published: October 2020

Over the last two decades, it has become clear that classical molecules that regulate neurodevelopment also play an important role in directly regulating the development of the vascular system and vice versa. The prototypical angiogenic ligand vascular endothelial growth factor (VEGF) is by now also regarded as a molecular regulator of different neurodevelopmental processes, such as neuronal progenitor proliferation, migration and differentiation, dendritic and axonal branching and synaptogenesis. The direct effect of other classical angiogenic factors, such as angiopoietins and its receptor Tie2, on neurodevelopmental processes remains less defined. Recent work from our group indicates that the angiopoietin-Tie2 pathway does not only regulate blood vessel formation and stabilization but also simultaneously affect neuronal dendritogenesis in a cell-autonomous manner. In this mini-review, we will integrate our findings within the current understanding of the neurovascular link and within the previous knowledge of the potential effects of angiopoietins in the neuronal context.

Fifty wheat seed variety (var.) CIRNO C2008 were gamma irradiated with 100, 200, 300, 400, 500, or 600 Gy by using a Cobalt-60 source at 907.39 Gy/h, and the nonirradiated seeds were considered the control (M
0). A photoperiod of 13 h of darkness (14°C) and 11 h of light (2 h at 18°C, 7 h at 25°C, and 2 h at 18°C) was used for 30 days, in a growth chamber (BJPX-A450; BIOBASE) for quantifying the morphometric traits of the irradiated vs nonirradiated seeds. The germination percentage (from 88.89% in M
0 to 77.78% in 600 Gy) did not show significant differences among treatments; while the survival percentage (from 100% in M
0 to 6.66% in 600 Gy) and plant height (from 19.21 cm in M
0 to 1.16 cm in 600 Gy) showed negative significant (p < 0.05) difference among nonirradiated seeds (M
0) and the rest of the treatments. Finally, based on the survival percentage, the calculated lethal dose was 290.6 Gy, which will allow obtaining promising wheat mutants. Gamma irradiation is a promising alternative to obtain a greater wheat variability for advanced mutant lines.

Farmers have not tested their soils for nutrient status and therefore are unaware of the fertility status of their soils. Therefore, a baseline fertility survey of 50 hectares of land of a gravelly Alfisol in the Teaching and Research Farm of Landmark University, Omu-Aran, Kwara State, Nigeria was carried out with a view to identifying soil health constraints and site-specific sustainable land management practices for optimizing crop production. Standard field protocols and laboratory analytical procedures were employed for all sample parameters measured. Results show that the soil textural classes vary from sand to loamy sand, exchangeable acidity, Ca, Mg, K, and Na and the effective cation exchange capacity has the surface and subsurface soil values of 0.0–0.92 and 0.00–0.89 cmol kg−1, 1.6–7.7 and 2.0–5.8 cmol kg−1, 1.2–11.5 and 0.7–8.0 cmol kg−1, 0.09–0.33 and 0.09–0.43 cmol kg−1, 0.0–0.16 and 0.04–0.16 cmol kg−1, 7.2–12.10 and 0.9–12.5 cmol kg−1, respectively. P values lie in the ranges of 2.5–68.9 mg kg−1 and 2.0–37.7 mg kg−1 in the surface and subsurface soils, respectively, organic C values were 0.86–2.81% and 0.68–3.49%, respectively, in the surface and subsurface soils while the values of N were 0.12–0.61% in the surface and 0.11–0.56% subsurface soils. Land evaluation shows that the soils of the project site are very fragile and poor in native fertility. Compound fertilizers low in nitrogen contents but high in phosphorus and potassium are recommended for gravelly Alfisol in a derived savannah ecological zone of the Kwara State, Nigeria to avoid a nutrient imbalance that may create artificial deficiencies of otherwise adequate nutrient elements.
Sicily Before the Greeks. The Interaction with Aegean and the Levant in the Pre-colonial Era
Authors: Tanasi Davide
Published: October 2020

The relationship between Sicily and the eastern Mediterranean – namely Aegean, Cyprus and the Levant – represents one of the most intriguing facets of the prehistory of the island. The frequent and periodical contact with foreign cultures were a trigger for a gradual process of socio-political evolution of the indigenous community. Such relationship, already in inception during the Neolithic and the Copper Age, grew into a cultural phenomenon ruled by complex dynamics and multiple variables that ranged from the Mid-3rd to the end of the 2nd millennium BCE. In over 1,500 years, a very large quantity of Aegean and Levantine type materials have been identified in Sicily alongside with example of unusual local material culture traditionally interpreted as resulting from external influence. To summarize all the evidence during such long period and critically address it in order to attempt historical reconstructions is a Herculean labor.

Twenty years after Sebastiano Tusa embraced this challenge for the first time, this paper takes stock on two decades of new discoveries and research reassessing a vast amount of literature, mostly published in Italian and in regional journals, while also address the outcomes of new archaeometric studies. The in-depth survey offers a new perspective of general trends in this East-West relationship which conditioned the subsequent events of the Greek and Phoenician colonization of Sicily.

Authors: Roy Debasish
Published: October 2020

This research paper is aimed at formulation of a composite Governance and Democracy Index (GDI) based on the six indicators of good governance by Kaufmannet al. (2003, 2007) to assess and evaluate therelativeperformances of 10 major democracies of the world for the time period of 20 years (1998 – 2017) (Base Year = 1996). In order to do so, three distinct methodologies are adopted based on the absolute values and relative changes in the observations of independent variables. The extended part of this research involves formulation of Governance, Democracy, and Emancipation Index (GDEI) which incorporates the Emancipative values.
Content Provision in the Media Market with Single-Homing and Multi-Homing Consumers
Authors: Garcia Pires Armando J.
Published: October 2020

In this paper, we analyze the effects on content provision in the news market of single-homing (i.e. when readers consume news from just one outlet) and multi-homing (i.e. when readers can choose to consume news from competing outlets). Media firms compete on content provision and on advertising revenues. Readers have an ideal variety of content and experience a disutility from consuming news that differs from their ideal variety. In addition, readers have a preference for single-homing and for multi-homing. In this set-up, we show that media firms only diversify content with single-homing, but not with multi-homing. The reason for this is that competition for readers and advertising is lower under multi-homing than under single-homing, since multi-homing readers consume from all media outlets. We derive the consequences of single-homing and multi-homing for profits, consumer surplus and social welfare. We also discuss the implications of our results for the current debate in the media market related with social media and echo chambers.
Nancy and the Idea of “Being-in-common”: An Alternative Existentiality for the Subjectivity
Authors: Basturk Efe
Published: October 2020

The aim of this article is to look at the discussion of the singularity in Jean-Luc Nancy’s philosophy as a quest to imagine a new concept of a common existence that negates the differentiation between “I” and the “other.” In the age of subjectivity, the main indicator of existence is the “subjectivity” that differs from the contingency and perceives itself as a whole in its autonomous singularity. This singularity-centralized perception of existence causes the negation of the being of the otherness and its ethical being that is the core element of establishing the subjectivity. Nancy, one of the leading philosophers offering new approaches on ethical subjectivity, tries to reflect upon a new idea about community (which is called in Nancy’s philosophy “being-in-common”), where the subjects can open themselves to the otherness. This article aims to claim that the idea of “being-in-common” is the only ethical opportunity to overcome the crisis that results from the sense of existence reduced to subjectivity. In Nancy’s thought, the ethical possibility of being-in-common should be interiorized within the concept of a communist democracy. A communist democracy is an opening of the being to its perfectibility in which the otherness is ontologically placed within the idea of the community.
Reverse localization on composite laminates using attenuated strain wave
Authors: Li Kun , Zhao Gang
Published: October 2020

Carbon Fiber Reinforced Polymer (CFRP) composite materials have been widely used in high-tech fields because of their outstanding physical properties. However, barely visible impact damage can be introduced by low velocity impact, which might bring tremendous risk. Monitoring impact forces is essential for the integrity and reliability of CFRP structures. In this paper, a reverse localization scheme on CFRP composite materials is developed. The scheme is based on a predictive mode of attenuated strain wave. The signals induced by low velocity impact are obtained by strain gauges. The proposed localization scheme has been verified by experimental tests of the CFRP plates with symmetrical stacking [0/45/90/−45]2s
The errors occurring in the test can be accepted for engineering application. The calculated impact locations are generally in consistent with the testing impact locations.
On the Contrasts Between sí ‘yes’ and sí que ‘yes that’ in Spanish and the Structure of the Complementizer Phrase Domain
Authors: Villa-García Julio , González Rodríguez Raquel
Published: October 2020

This paper aims to account for a host of old and novel syntactic contrasts between the emphatic polarity particle sí ‘yes’ and its putative counterpart with an instance of the complementizer que –sí que ‘yes that’ in Spanish. Even though the two constructions appear to be synonymous in certain contexts, closer inspection reveals that the two elements display a number of non-trivial asymmetries in their behavior and distribution and convey different meanings. We thus argue that the two elements should be treated differently. Building on Hernanz (2007 and subsequent work), we propose that sí, which marks focal positive polarity, i.e., verum focus, originates in ΣP and then moves to FocusP. By contrast, sí que is directly merged in a projection below TopicP but higher than FocusP in the left periphery, does not encode polarity, and instead renders the meaning that the speaker is extremely confident about the propositional content, be it positive or negative. We argue that sí que involves more CP structure than sí, which makes a variety of correct empirical predictions.
Thanatologische Begriffsbestimmungen: Beitrag zu einer Humanisierung der Medizin am Lebensende
Authors: Valdés-Stauber Juan
Published: October 2020

Hintergrund:Aus ontischer Sicht ist der Tod ein Ereignis im zeitlichen Daseinshorizont, ontologisch betrachtet eine Wesensbestimmung, die vernichtend und zugleich konstituierend für das biografische Leben ist. Der Tod ist in der Erste-Person-Perspektive nicht erfahrbar; das Bewusstsein des Todes ist somit ein Gewahrwerden des Sterbenmüssens. Die Konfrontation mit dem Todsein geschieht in der Zweite- und Dritte-Person-Perspektive.Fragestellung und Methode:Die vorliegende Arbeit befasst sich mit der definitorischen Intension und Extension des Begriffes „Tod“. Anhand des semantischen Feldes von „Sterben“ und „Tod“ wird untersucht, inwiefern eine Begriffsanalyse zu einer Humanisierung der Medizin am Lebensende beitragen kann.Ergebnisse:Es werden fünf Dimensionen des Begriffes „Tod“ unterschieden: Sterblichkeit, Vernichtungsprinzip, Sterbeprozess, ontologische Grenze, Zustand des Totseins (abwesend in Anwesenheit). Eine Berücksichtigung der anthropologischen Sichtweise für die Medizin bei der Versorgung von Menschen an ihrem Lebensende sollte folgende Aspekte beinhalten: die Frage, wie Leben und Tod sich gegenseitig befruchten können; die Sorge über die körperbezogene Pflege; die personale Besetzung der Begriffe „Hoffnung“ und „Zuversicht“; neben der Behandlung und Linderung die Haltung als verlässliches, aufnehmendes und nicht moralisierendes Gegenüber.Diskussion:In unserer Zeit dominieren medizinische und psychologische Perspektiven auf den Tod, die einer philosophischen Kritik bedürfen. Die Einsamkeit des Sterbenden innerhalb einer zunehmenden Medikalisierung des Sterbens und des Todes wird hervorgehoben.
MRI Ideas as a Compass in the Dark: A Beginning Therapist Applies MRI Ideas to Dangerous Situations
Authors: Popham Jessica , Rambo Anne
Published: October 2020

The foundational ideas of the Mental Research Institute (MRI) can offer grounding to a therapist when working with dangerous or emotionally fraught situations. In this article, a beginning therapist discusses how these foundational ideas helped her overcome initial biases to work successfully with potentially dangerous court-mandated clients; helped her to handle an emotionally fraught situation in her own family; and clarified her work with a client in a potential domestic violence situation, which might have required reporting to child welfare authorities. Key MRI concepts including the theory of groups; the theory of logical types; first and second order change, cybernetics and positive and negative feedback; context-maintaining behaviors; attempted solutions which become problematic; and therapist maneuverability are discussed. Basic MRI interventions are defined and discussed, including but not limited to the go-slow directive, the dangers of improvement, making a “U-turn,” and how to worsen the problem. A case study is presented.
The Evolution of a Point of View: The Enduring Personal Influence of the Mental Research Institute
Authors: Fraser J. Scott
Published: October 2020

This work honors the work of the Mental Research Institute (MRI) in Palo Alto, California, upon the sale of the building it long occupied, and particularly the closing of the MRI Brief Therapy Center as a research and training center. The major position of the article is that the MRI was much more than a place, a name, or the people who have been part of it. Instead, the ideas and practices of those who have been part of the MRI are what endure and thrive. As a case in point, the author follows his own professional journey from his first contact with the MRI ideas as a “difference that made a difference” through his present day work.

Published: October 2020

The main point of this study is to investigate the optimal conditions for preparation of activated carbon from wood sawdust (ACWSD) for removal of hydrogen sulfide (H2S) from wastewater. The response surface methodology (RSM) was employed to prepare the ACWSD by chemical activation with potassium hydroxide (KOH). The threepreparation  variables impact of activation temperature (724 – 1000 °C), KOH: precursor (wt%) impregnation ratio (IR) (2:1 – 4:1) and activation time (60 – 120 min) on removal efficiency (RE, %) of H2S and activated carbon yield (ACY, %) were investigated. The preparation parameters were correlated by developing a quadratic model depend on the central composite design (CCD) to the two responses. The analysis of variance (ANOVA) was identified the most influential variable on each experimental design responses. The results showed that the temperature of 854 °C, chemical impregnation ratio of 2.95 wt% and activation time of 80 min were the optimum conditions for preparation of ACWSD with responses of RE and ACY of 72.88 % and 31.89 %, respectively. It is concluded that the ACWSD was appeared to be a favorable substance for removal of dissolved H2S from synthetic wastewater.
OPTIMIZATION ON DYEING UPTAKE EXHAUSTION PERCENTAGE OF BETACYANIN PIGMENT EXTRACTED FROM HYLOCEREUS POLYRHIZUS PEEL ONTO THE SPUN SILK YARN USING CENTRAL COMPOSITE DESIGN
Authors: Hamid Norasiha , Abd Munaim Mimi Sakinah
Published: October 2020

The prior motivation of this research study is to determine the ideal condition for dyeing process of spun silk yarn with natural dye extracted from dragon fruit peel using a central composite design. The peel of dragon fruit is contained betacyanin pigment can be utilized to be a natural dye which normally the peel of dragon fruit was discarded as a waste. As the betacyanin pigment was considered to be a newest red dye color in textileapplication, it is necessary to determine the optimal value for its specific dyeing process. In this experiment, natural dye was extracted from dragon fruit peel using water extraction with the acidified water as a medium. The natural dye was then applied onto the spun silk yarn at different dyeing time (60 – 90 min), pH (3 – 5) and dye concentration (100 –120 g/L). The dye-uptake of natural dye was measured using UV-Vis spectrophotometer. The result of dye-uptake percentage was employed using analysis of variance (ANOVA). By ANOVA, the dyeing condition was determined as pH of 2, dyeing time of 95 min and the dye concentration of 110 g/L which is generated from the mathematical model. Using the ideal condition, the dye uptake percentage was determined to be 51.58% to a desirability value of 0.995. So, it is concluded that dyeing condition for the optimal value of dyeing uptake exhaustion of betacyanin pigment onto the spun silk can be determined using CCD.

Published: October 2020

Thermodynamic modelling, experiment, measurement, and characterization technique were used to evaluate the leaching process of yttrium (Y) elements from liquid crystal display (LCD) electronic waste (e-waste). Thermodynamic modelling using HSC 6.0 software revealed that the reaction of leaching out Y with hydrochloric acid is endothermic thus absorbing heat and at the same time positive Gibbs free energy from temperature 273.15 K to 343.15 K and negative Gibbs free energy from temperature 353.15 K to 373.15 K. Thermodynamic data of the leaching processes with sulfuric and nitric acids show that the reactions are exothermic thus release heat and at the same time negative Gibbs free energy from temperature 273.15K and above. The leaching reaction with sulfuric and nitric acids identified to be reversible from temperature 273.15 K and above due to the negative entropy change, whereas the reaction was found irreversible for the hydrochloric acid solution due to the positive entropy change at the similar minimum temperature setting. The significance of reversibility versus irreversibility is their relationship to the efficiency. The equilibrium constant show that the leaching process with hydrochloric acid is less than 1 (Log K<1) from temperature 273.15 K to 343.15 K indicate that the backward reaction is favored while from temperature 353.15 K to 373.15 K have a positive equilibrium constant (Log K>1) thus indicate thatforward reaction is favored. Leaching process with sulfuric and nitric acids shows that the positive equilibrium constant (Log K>1) which indicate that forward reaction is favored from temperature 273.15 K and above. The Pourbaix diagram modelling showed that Y dissolved in HCl at pH below 7 therefore strong reducing agents such as sulfuric acid (sulfide) can improve the dissolution of Y. Inductively coupled plasma mass spectroscopy (ICP-MS) results showed that only Y is viable to be efficiently leached from the studied LCD, e-waste either in a single-stage or in two-stage leachingmode. Sulfuric and nitric acids are found to be the most practical solutions in leaching out the Y element whereby around 0.00515 ppm and 0.00507 ppm of Y were dissolved in both solutions respectively based on the two-stages leaching approach.
