Light Scattering by Noble Metallic Nanoparticles for Performance of Compound Solar Cells Enhancement
Authors: Nguyen Lam Dinh
Published: October 2021

Light scattering by noble metallic nanoparticles are of interest for a variety of applications due to the large electromagnetic field enhancement that occurs in the vicinity of the metal surface, and the dependence of the resonance photon energy on the nanoparticle size, shape, local dielectric environment, and material. Here, the influences of electromagnetic scattering by Au and Ag nanoparticles placed atop compound solar cells on optical absorption and photocurrent generation were investigated based on the variation in the noble nanoparticle densities. The results indicated that the short-circuit current and power conversion efficiency were strongly affected by the density and material of the noble nanoparticles. The great improvement of 28% in power conversion efficiency can be obtained with Au nanoparticle density of 2\(\times\)108 cm-2. This improvement can be attributed to light scattering, light trapping, and surface roughness by noble nanoparticles. Furthermore, Au nanoparticles showed more efficient in solar cell power conversion efficiency improvement than Ag nanoparticles did although density of Au nanoparticle was lower than that of Ag nanoparticles.

Abstract The present study was a prospective, controlled, randomized, clinical short-term trial aiming to evaluate the clinical performance of adhesively luted, lithium disilicate and feldspathic glass-ceramics onlays over a period up to 2 years. A total of 11 patients (7 female, 4 male; age range: 18-60 years, mean age: 39 years) were selected for this study. Each patient received a maximum of two restorations per group in a split-mouth-design. LD: Eleven onlays, performed with lithium disilicate-based ceramic (IPS e.max CAD, Ivoclar Vivadent, Schaan, Liechtenstein), and FP: Eleven onlays, performed with feldspathic ceramic (Vita Mark II, Vita Zanhfabrik, Bad Säckingen). Recalls were performed at 2 weeks (baseline = R1), 1 year (R2) and 2 years (R3) after the cementation by three calibrated blinded independent investigators using mirrors, magnifying eyeglasses, probes and bitewing radiographs. The postoperative sensitivity, secondary caries, marginal integrity, marginal discoloration, color match, surface roughness, tooth integrity, and restoration integrity were evaluated. The Friedman test was used to determine if there was a statistically significant difference in time-to-time comparison of the parameters in the ceramics restorations. A total of 95.4% of the restorations were clinically acceptable at the 2-year recall, without a difference for any evaluation parameter for both ceramic materials. Based on the 2-year data, the CAD-CAM onlays manufactured with feldspathic and lithium-disilicate based ceramics showed similar clinical performance.

Published: October 2021

Abstract This study aimed to analyze the maxillary growth and development of children with oral clefts using the innovative method of 3D-3D superimposition technique. Children with unilateral complete cleft lip (UCL) and unilateral cleft lip and palate (UCLP) participated in the study. The impressions of the dental arches were executed 1 day before and 1 year after lip repair surgery. A 3D laser scanner digitized the dental models and the stereophotogrammetry system software analyzed the 3D-3D superimpositions in two groups of matches (same child, UCL and UCLP) and one group of mismatches (different individuals). The differences were evaluated by Root Mean Square (RMS) and expressed in millimeters (mm). Kruskal-Wallis test followed by post-hoc Dunn test and Mann-Whitney test were assessed to compare the groups (α=5%). RMS was 1.34 mm (± 0.37) in UCL group, 1.41 mm (± 0.32) in UCLP group, and 3.38 mm (± 1.28) in mismatches group. RMS was significantly greater in mismatches than in matches groups (p<0.0001). No statistically significant differences occurred between genders. The 3D-3D superimposition technique showed the maxillary development after lip repair surgery in the anterior region of the palate. Thus, it is suggested that the cleft amplitude and the palatal segments proportion influenced the morphological heterogeneity and, consequently, the development and maxillary growth of children with orofacial cleft.

Abstract Galaxias maculatus aquaculture objectives is to produce millions of eggs. Wild females are small (2 g), have quick sexual maturity and low mean fecundity (500 eggs/female), requiring larger fishes with higher fecundity. This study aim is to evaluate experimentally the effect of the levels of protein, lipid and dietary energy on weight increases in adults. Five independent experiments were performed at different sequential time periods at the UCT hatchery, Chile. Specimens were obtained from a) Crystalline sea return specimen catches in the Tolten estuary (4 -6 cm, 0.3-0.4 g.). b) Hatchery cultured fish. Fish were fed by hand ad libitum. In experiments 1 to 4, pelleted diets were prepared with 3 to 5 levels of protein (treatments 27 up to 57%), crumble size, three 100 L fibre ponds replicates. In experiment 5 the effect of two lipid levels (8 and 21%) was evaluated with commercial extruded Salmon Nutra Starter isoproteic crumble 1 diet at 63%, replicated in 4 ponds. The results show: A tendency to increased weight in all sizes with an increased protein level in the pelleted diet.A maximal adult growth is obtained with a diet containing a minimum of 37% crude protein, with 40% the optimal value. A higher % protein in the diet or growth in weight lower feed conversion ratio. The feed conversion ratio in the extruded diet reaches up to 0.5 and in the pelleted vary from 0.7 to 1.5. Fish 0.6 g fed with 63% protein, extruded commercial diet with two different lipid levels (8 and 21%, 20.40 and 23.84 MJ kg-1, PE/TE 0.62 and 0.71) increased weight the first month 67 and 105% each. It has been established that high-energy diets with optimal levels of protein and lipid are a good short-term solution to obtain G. maculatus of higher weight.

Published: October 2021

ABSTRACT Purpose: This study evaluates the role of social networks of support, information, and trust in well-being at work, regarding the positive and negative affects and professional fulfillment of workers immersed in processes of organizational change. Originality/value: Organizational change is characterized as a dynamic process, constituted through relationships, immersed in a context of uncertainties. The mapping of relationships can help in understanding the information flows and the assessment of resource availability. Design/methodology/approach: 151 professionals from a holding participated. This company undergoes changes in the scope of services offered and the organizational design. Links of support, information, and trust established according to the change processes were mapped. Associated with the network, the Well-Being at Work Scale was used. For data analysis, multiple regressions were used to construct explanatory models for well-being factors: fulfillment, positive and negative affects. Findings: Variables in support and information social network analysis (SNA) composed the predictive model of well-being in the three models. Among the researched ties, the support and information ties were part of the predictive model of well-being. The metrics that reveal how many times the employee is indicated and indicates others, proximity to highly cited neighbors, degree of participation in cohesive subgroups, the degree to which they assume a central position in the subgroups are indicators of actors’ positions capable of predicting well-being. The influence of the pattern of interaction between managers and employees should be considered in promoting well-being in organizations in the process of change.

ABSTRACT Purpose: This paper aims to understand the configuration of strategic entrepreneurship practices of exploration, exploitation, and ambidexterity in craft breweries from Uberlândia, MG. Originality/value: Strategic entrepreneurship enables the comprehension of entrepreneurial phenomena from an organizational perspective. Furthermore, this research is conducted in an emergent industry in Brazil, with few studies in the field of management that consider the idiosyncrasies of craft breweries. Design/methodology/approach: We conducted a qualitative multicase study with three craft breweries from Uberlândia, MG. Twelve interviews were performed, and the set of empirical data collected were analyzed through narrative analysis technique. Findings: We identified several strategic entrepreneurship practices in the craft breweing sector. First, exploration practices were found in some radical innovations, such as the pioneering nature in the production of craft beers in Uberlândia, the creation of new products, and in the setting of new business models. Second, exploitation practices were also identified in incremental innovations that enabled business development. Hence, ambidexterity relied on the balance of exploration and exploitation practices, as innovative endeavors enabled the creation and development of new products and access to new markets. Thus, strategic entrepreneurship practices reflect the initiatives of entrepreneurial agents that seek to promote organizational innovations in terms of quality improvements, new production and marketing strategies, and the adoption of new technologies. Therefore, strategic entrepreneurship reflects and contributes to innovation possibilities, strategic renewals, and the competitiveness of craft breweries, revealing the analytical power of this theoretical approach for the study of entrepreneurial phenomena.
Medindo a massa inercial usando uma balança romana
Authors: Kinouchi Osame , Menesse Gustavo , Stoli Jorge
Published: October 2021

Apresentamos um aparelho simples de laboratório didático para medição de massa inercial, baseado no equilíbrio quase-estático de uma balança de peso deslizante (balança romana) num plano horizontal, suprimindo a influência da gravidade. O dispositivo oferece uma definição operacional alternativa da massa inercial. Comparada com definições tradicionais baseadas em medidas de aceleração (como a definição clássica de Ernst Mach) ou da frequência de um sistema massa-mola, este método não exige medições de tempo, força, ou acelerações; utiliza um aparato simples e barato; e fornece o valor correto mesmo se executado em um sistema não-inercial, ou por um observador em movimento relativístico. O aparato também permite medir a massa gravitacional, e demostrar sua equivalência com a massa inercial de maneira simples e elegante. Por estas razões, o método é eminentemente adequado para demonstrações em classe e aulas práticas em cursos introdutórios de física.

Published: October 2021

In this work, the glass system of 3.95Li2O–9.95Na2O–0.85Al2O3–(100 − x)SiO2–9.25CaO–4.7MgO–3.8ZnO–xCeO2, where x is 0, 2.5, 5.0, 7.5 and 10.0 mol%, was investigated for a potential use in radiation-shielding applications. For this purpose, the newly developed Phy-X/PSD software was utilized to determine the radiation-shielding characteristics in the proposed lithium (Li)–zinc (Zn)–silicate (LZS) glass system. Based on the linear attenuation coefficient (LAC) calculations, the half-value layer (HVL) and the radiation protection efficiency were evaluated for the glass series. Further, some physical properties such as glass density (ρglass), molar volume (Vm), oxygen molar volume and oxygen packing density were estimated, while various optical features such as refractive index (n) and metallization criterion (M) were also assessed. The findings clearly showed that the addition of cerium (IV) oxide (CeO2) in the LZS glass system was a good choice for improving radiation-shielding characteristics – that is, the LAC was efficiently enhanced from 0.145 to 0.166 cm−1at 1.5 MeV as the concentration of cerium (IV) oxide was increased from 0 to 10 mol%. On the other hand, the HVL decreased from 3.066 to 2.592 cm for LZS0 to LZS4. Moreover, the physical calculations revealed that ρglasscould be increased from 2.8181 to 3.2751 g/cm3with the addition ratio of cerium (IV) oxide as 0–10 mol%, respectively. More importantly, LZS4, having the highest cerium (IV) oxide content, can compete with commercial radiation-shielding glasses.
Akkreditierung im Schmittianismus? Ein Kommentar
Authors: Mehring Reinhard
Published: October 2021

«Dr. Münkler, Judengasse 11, 636 Friedberg/H»: Im Februar 1982 weist Günter Maschke Carl Schmitt auf die Schriften eines jungen Politikwissenschaftlers hin. Maschke war bereits von der radikalen Linken konvertiert, wenn auch noch nicht der exponierte Promoter der radikalen Neuen Rechten, als der er heute bekannt ist. Als Verleger stand er mit Schmitt in enger Verbindung. Der 93-jährige Schmitt nimmt nun den direkten Kontakt mit dem über 60 Jahre jüngeren, gerade erst über Machiavelli promovierten «Dr. Münkler» auf. Dieser arbeitet am Lehrstuhl von Iring Fetscher – wo den realpolitischen Strategen der Ideengeschichte nachgespürt und weniger Berührungsscheu mit Themen des weltanschaulichen Gegners gehalten wurde als am benachbarten Institut für Sozialforschung.

Als der deutsche Staatsrechtler Ernst Rudolf Huber am 24. November 1941 im Alter von achtunddreißig Jahren die Rede zur Eröffnung der Reichsuniversität Straßburg hielt, war dies ein besonderer Moment. Für ihn selbst bedeutete dies ganz sicher den Höhepunkt seines bisherigen wissenschaftlichen Lebens. Er repräsentierte die deutsche Rechtswissenschaft und stand an der Spitze der zu gründenden Rechts- und Staatswissenschaftlichen Abteilung in einer Fakultät von Juristen und Nationalökonomen, die sich als modern und zukunftsweisend verstand. Zudem bedeutete die Eröffnung in Straßburg für viele der Beteiligten eine «Rückeroberung» des Elsass nach über zwanzigjähriger französischer Herrschaft und darüber hinaus die Hoffnung auf eine Revitalisierung der Wissenschaften unter reichsdeutschen Vorzeichen. Huber persönlich verstand seine Berufung, das kommt in vielen Passagen seiner Straßburger Erinnerungen zum Ausdruck, als eine «Rückkehr in das gesegnete rheinische Land»..
Zwei Universitäten im Krieg

Pierre Noras Werk Les lieux de mémoire enthält in seinem zweiten Teil La Nation einen Artikel, der sich mit dem Elsass als «Erinnerungsgrenzraum» befasst, der «von den Erinnerungen an eine zwischen Frankreich und Deutschland hin- und hergerissene Geschichte beherrscht» wird.1 Die Universität Straßburg gehört für die Zeit zwischen 1939 und 1945 sicher zu den Kristallisationspunkten dieses Erinnerungsortes, zunächst als Streitobjekt, später als erinnerungspolitisches Problem. Die französische Universität Straßburg im Exil Die Ursprünge der Universität Straßburg gehen auf die Folgen der Reformation Ende des 16. Jahrhunderts zurück. Nach dem Deutsch-Französischen Krieg, der Gründung des Deutschen Reichs und der darauf folgenden Etablierung einer deutschen Universität im Elsass erlebte die Institution ihre akademische Blütezeit, die auch nach der Rückkehr zu Frankreich in den 1920er-Jahren noch anhielt.

Als sich das Deutsche Reich 1871 das Elsass einverleibte, begann sogleich der Ausbau Straßburgs zur modernen Grenzfestung. Nur wenige Monate später wurde die Kaiser-Wilhelms-Universität gegründet. Man könnte von «Leuchtturmprojekten» sprechen, aber es waren nationale Wachtürme und Aussichtsplattformen, denn Straßburg wurde durch Grenzfestung und Universität vor allem zu einem Ausguck. Albert Schweitzer blickte von hier aus weit über die Grenzen der Theologie hinaus. Friedrich Meinecke wurde zum Ideenhistoriker, Ernst Robert Curtius zum Romanisten. Für alle war Straßburg nicht das Ziel der Karriere, sondern Startpunkt, Passage oder Brückenkopf, wenn sie nicht wie Georg Simmel das Pech hatten, vorzeitig in Straßburg zu sterben.
Vom Elsass nach Jerusalem. Die unvollendete Suche des Claude Vigée
Authors: Raphaël Freddy
Published: October 2021

Meine persönliche Annäherung an Claude Vigées Weg vom Elsass nach Jerusalem und darüber hinaus erfolgt in drei Etappen.Am Beginn steht das Land der Sümpfe, des Nebels und des Regens, das er 1939 verlassen musste. Es folgt das unverhoffte Ende des Exils 1960: die überwältigende Entdeckung der unermesslichen Weite des Himmels über dem Gelobten Land und des von Adern durchzogenen Felsens der dreimal heiligen Stadt. Und doch war dies nicht der Ort, an dem die Suche Claude Vigées an ihr Ziel kam. Sie führte den Dichter, der beständig unterwegs war, vielmehr bis in sein tiefstes Innerstes. Verbundenheit und Entwurzelung aus der ersten Heimat: dem Elsass Seit seiner frühen Kindheit war Claude Vigée von der rheinischen Natur der Umgebung des Marktfleckens Bischweiler, in dem er aufwuchs, geprägt. Diese Gegend ist eine «lichte, zarte, etwas schwermütige Landschaft mit Sümpfen, Schilf und toten Wasserläufen unter ergrauten Ästen».Wenn es regnete im Herbst, schwänzte der Junge oft die Schule.

In meinen letzten Schuljahren hat mich eine Faszination für kulturelle Wenden gepackt. Der Auslöser dieses Interesses mutet einigermaßen abgelegen an. In der Obertertia oder Untersekunda (wie es damals hieß) schlich ich mich an den entsprechenden Nachmittagen der Woche in die Universität, um der Vorlesung des Musikwissenschaftlers Thrasybulos Georgiades zu folgen, den ich hoch verehrte. Es ging um die Wende vom Barock zur Klassik, das heißt um die Musik der «Vorklassik» und näherhin um die Symphonien von Giovanni Battista Sammartini (1700–1775). So muss Kulturwissenschaft vorgehen, nahm ich mir vor: derartige Wendezeiten in all ihren Ausdrucksformen in den Blick zu bekommen.

Werteskala der politischen Gewichte

Hans-Dietrich Genscher, parlamentarischer Geschäftsführer und im Windschatten von Walter Scheel der kommende Mann der FDP, ärgerte sich kurz vor dem Jahreswechsel 1965/66 über einen jungen Professor, der mit wenigen Strichen die Koalitionsverhandlungen des zweiten Kabinetts Erhard karikierte. In der letzten SPIEGEL-Ausgabe des Jahres hatte Jürgen Habermas die Besprechung von Ralf Dahrendorfs Traktat über Gesellschaft und Demokratie in Deutschland zum Anlass genommen, der FDP eine rückwärtsgewandt-nationale Haltung zu attestieren. Während der junge liberale Starintellektuelle seiner künftigen Partei (er sollte erst 1967 eintreten) die soziale Frage ins Stammbuch schrieb, wie Habermas zustimmend referierte, hingen die Freidemokraten noch «gesamtdeutschen Imaginationen» nach.

In der Einleitung «Wozu noch Philosophie?» zu den Philosophisch-politischen Profilen (1971) bemerkt Jürgen Habermas über die Fixierung der Nachkriegsphilosophie auf den Faschismus, die «Gewalt dieses objektiven Vorgangs» habe alle Lager polarisiert: das der Exilierten ebenso wie das der inneren Emigranten und der «intellektuellen Vorreiter oder temporären Nothelfer des Regimes wie Heidegger, Freyer und Gehlen.» Freilich, so fährt Habermas fort, «hätte diese biographische Hypothek ihr Gewicht nicht über zwei Jahrzehnte behalten können, wenn nicht das Problem der mittelbaren intellektuellen Urheberschaft politischer Verbrechen [...] bestanden hätte und als systematische Frage doch zugleich unerledigt geblieben wäre.»

Nicht nur in Gesprächen hat sich Jürgen Habermas immer wieder und anscheinend gerne als «Produkt der amerikanischen Re-Education» beschrieben, wie es unter deutschen Intellektuellen mit ganz verschiedenen politischen Positionen – und aus ganz verschiedenen Gründen – in seiner wie der folgenden Generation nie selbstverständlich geworden ist. Eine solche Referenz setzt die Opfer der westlichen Alliierten beim Sieg über den Nationalsozialismus dankbar voraus, rückt das historische Verdienst der von ihnen geschaffenen Institutionen als Weg zu einer stabilen Demokratie in den Vordergrund und schließt oft – uneingestanden – den Gedanken an die Vereinigten Staaten als «Weltmacht» ein.

In this paper, we study the strong non-stationary stochastic processes that take place in the phase space of self-gravitating systems at the earlier non-stationary stage of their evolution. The numerical calculations of the compulsive phase mixing process were carried out according to the model of chaotic impacts, where the initially selected phase volume experiences random pushes that are of a diverse and complex nature. The application of the method for studying random impacts on a volume element in the case of three-dimensional space is carried out.

Published: October 2021

The objective of this work was to study the suitability of three types of cast iron for the manufacture of a ship engine: EN-GJS-500-7U for the manufacture of the engine block, EN-GJS-400-15U for the cylinder head and EN-GJL-200 for the liner. Tensile tests were carried out to obtain the ultimate tensile strength (UTS) of each material. The results for the UTS were: 460 MPa for EN-GJS-500-7U, 390 MPa for EN-GJS-400-15U and 170 MPa for EN-GJL-200. Likewise, Brinell-hardness measurements were carried out and the elements present in the materials were determined with spectrometry. Finally, the size of graphite particles in each sample was determined.
EXPERIMENTAL STUDY ON THE DYNAMIC SHEAR MODULUS AND DAMPING RATIO OF SATURATED SAND UNDER CYCLIC LOADING
Authors: Zhang Jian , Cao Jiuting , Huang Sijie , Shi Baocun
Published: October 2021

Initial shear stress is inevitable in actual engineering slopes, subgrades and foundations, and soils exhibit different dynamic characteristics under the influence of initial shear stress. Using a dynamic triaxial test system, this study explores the dynamic shear modulus and damping ratio of saturated sand from Wenchuan, investigates the effects of the initial shear stress and vibration frequencies on the dynamic shear modulus and damping ratio of saturated sand and proposes a normalised dynamic shear modulus formula that considers the initial shear stress and vibration frequency. Results show a threshold dynamic shear strain of the saturated sand. When the dynamic shear strain is below this threshold, the dynamic shear modulus significantly increases with the initial shear stress and vibration frequency. Otherwise, the influence of the initial shear stress and vibration frequency gradually decreases and eventually stabilises. The initial shear stress significantly affects the normalised dynamic shear modulus/strain curves where a larger initial shear stress corresponds to a higher curve. Meanwhile, the vibration frequency only exerts a slight influence. The curves under different frequencies are generally within the same band and fall near the Seed upper envelope. The initial shear stress also has a significant influence on the damping ratio where a larger initial shear stress corresponds to a smaller damping ratio. On the basis of the experimental results, a normalised dynamic shear modulus/shear strain formula that considers the influence of the initial shear stress and vibration frequency is established. Fitting results indicate that this formula shows good agreement with the test data.

Published: October 2021

A city is made of multiple places. Notably, Rio de Janeiro's Copacabana is full of many features that contribute to its worldwide recognition. In this context, this paper aims to highlight the intimate link between the beach and volleyball. In order to do so, the methodology consists of bibliographical research. The historical and theoretical data collection allow the analysis of government programs related to enhancing the practice of sports and leisure. It is known that leisure activities (and their regulations) in Copacabana Beach Boardwalk have definitely changed over the last hundred years. Ultimately, this research concludes that volleyball at the beach is worth special attention since it is a piece in the puzzle of Rio de Janeiro’s landscape and a great urban social activity.
La confianza de los estudiantes de traducción en la traducción automática: ¿demasiado buena para ser verdad?
Authors: Torres-Simón Ester , Pym Anthony
Published: October 2021

Advances in neural machine translation have reached the point where professional translators can work faster and produce better terminology when post-editing machine translation as opposed to fully human translation. Most translator-training programs thus include courses in how to post-edit machine translation. Many professional translators, however, are opposed to the use of post-editing rather than fully human translation, resulting in a suite of negative opinions about machine translation within the teaching situation. Here we report on two cases in which classroom activities with translation students involved the post-editing and evaluation of machine translation. We assess the students’ actual performances in the two modes (fully human translation as opposed to the post-editing of machine translation), which we then compare with the students’ comments on machine translation and their personal experience with it. It is found that although the students generally recognized the greater efficiency of post-editing, they nevertheless remained generally opposed to machine translation in principle, indicating extensive resistance within the learning community.

Oil palm empty fruit bunch (EFB), a cellulose rich lignocellulosic biomass has huge potential to be utilised as a raw material for the synthesis of carboxymethyl cellulose (CMC). In this study, CMC was synthesised from EFB extracted cellulose at the optimum carboxymethylation reaction conditions. The extracted cellulose yield obtained by alkaline treatment followed by bleaching with hydrogen peroxide was 45.5 wt.%. The cellulose structure was elucidated using thermogravimetric analysis (TGA), Fourier-transform infrared spectroscopy (FT-IR) and X-ray diffraction (XRD) patterns. Meanwhile, the synthesised CMC was characterised with FT-IR, XRD and scanning electron microscopy (SEM). The maximum degree of substitution (DS) obtained was 1.30 with the yield of 177.51 wt.% and purity 89% determined using chemical methods at the optimum conditions of 30 wt.% of NaOH, 18 g of SMCA, 65 °C, 3 h reaction time and less than 75 μm of EFB-cellulose particle size. XRD analysis inferred low crystallinity while FTIR spectra verified the CMC structure and presence of different functional groups. The results for DS and EFB CMC yield obtained from this work were considerably higher than those reported in the literature. The synthesised EFB CMC can be further utilised in various industries such as detergent, mining, flotation, and oil and gas drilling muds applications.

Asparagus spear is vulnerable to microbial groups which can cause deterioration and short shelf-life after harvesting. The effects of cold plasma, coupled with modified atmosphere (MA) packaging on microorganism development, and quality changes of green asparagus were investigated. The development of microorganisms was inhibited after sterilisation. After 21 days of storage, cold plasma for 6 h (P6h) and hot water combined with cold plasma for 3 h (HW+P3h) treatments obtained the lowest number of aerobic bacteria. Hot water (HW), P6h and HW+P3h treatments showed higher inhibition effect on yeast and mold, and also on E. coli. Visual quality and off-odour of P6h treatment were superior to and inferior to other treatments, respectively. Hot water and cold plasma treatments alone inhibited the firming. Cold plasma 1 (P1h) and 3 h (P3h) were better in retarding yellowing of asparagus. A difference in electrolyte leakage (EL) between control (43%) and sterilisation treatments (greater than 60%) was immediately observed on the sterilisation day. Treatments using HW and P1h decreased the EL after 21 days. The soluble solid content (SSC) decreased based on the initial content, and hot water treatment resulted in higher SSC. Increases in ethylene (C₂H₄) and carbon dioxide production and decrease in oxygen were observed during the first 3 days. The content of C₂H₄ under cold plasma treatments was higher than hot water and control on day 21. These results suggested that cold plasma 6 h treatment resulted in better sensory quality and less decay and softening for green asparagus.

Linum usitatissimum (Flaxseed) is known to be traditionally used for managing hypertension. In this study, we aim to provide a mechanistic basis for the medicinal use of Flaxseed in hypertension. The high-performance liquid chromatography (HPLC) analysis that we carried out during our study showed the presence of polar compounds (quercetin, nicotinic acid, and nicotinamide) in Flaxseed’s crude extract (Fs.Cr; aqueous methanolic). In anesthetized rats, Fs.Cr reduced arterial blood pressure (BP) dose-dependently (10-100 mg/kg). When tested for its mechanism of action ex vivo, Fs.Cr inhibited both the force and rate of spontaneous contractions in the dose range of 1-10 mg/mL in isolated guinea-pig atria, similar to how verapamil, a standard Ca+2 channel blocker does it. Further, Fs.Cr showed vasodilator effect against the contractions induced by phenylephrine (PE, 1 μM) in rat aortic ring preparations (concentration range: 1-10 mg/mL), whereas no effect was observed against the contractions induced by low K+ (25 mM) as well as high K+ (80 mM). This selective inhibitory effect of Fs.Cr against PE was tested for endothelium-dependent nitric oxide (NO) and/or cholinergic component involvement. The vasodilator effect of Fs.Cr against PE was retested in the absence and presence of atropine in endothelium (E)-intact and E-denuded aorta, but no significant shift was observed in the inhibitory effect of Fs.Cr. Further, Fs.Cr shifted the PE-induced concentration-response curves (CRCs) to the right in a dose-dependent manner (1 and 3 mg/mL). This effect was similar to that of prazosin. All these findings indicate that Flaxseed may mediate its antihypertensive activity by the alpha-1 receptor antagonist and Ca+2 channel blocking-like activity, which may account for its efficacy in hypertension.

Trabeculectomy is the gold standard procedure performed in glaucoma when topical medication and laser intervention failed. In a trabeculectomy, number of clinical trials have shown the efficacy of ranibizumab in minimizing extracellular matrix accumulation at the filtering site. Ranibizumab (LucentisTM) is a drug that targets vascular endothelial growth factor (VEGF). However, to date the actual mechanisms of this anti-VEGF in trabeculectomy is still not well understood. Hence, in here we aimed to elucidate the effects of ranibizumab on human Tenon’s fibroblast (HTF) isolated from patients undergoing trabeculectomy. In our previous study, we had reported that ranibizumab reduces the level of spermidine metabolite whereby spermidine is an important polyamine for cell proliferation. For this current study, cultured HTFs were divided into untreated, control IgG, ranibizumab only, difluoromethylornithine (DFMO; inhibitor of spermidine) only and ranibizumab with DFMO. All cells were extracted for PCR array (expression of CDKN1A, CDK2, and CDK4) and protein expression of p53, p21, CDK2, and CDK4 by Western Blot. In here, our result demonstrated that cells treated with ranibizumab or DFMO and cells treated with ranibizumab-DFMO have similar effects as both show increased in p53 and p21. Meanwhile, no significant differences in expression of CDKN1A, CDK2 and CDK4 were observed in all groups. In essence, our findings suggest that ranibizumab action is mediated by p21 and p53.

The emergence of COVID-19 pandemic has caused difficulty to emergency-HCW (EHCW) in resuscitating high-risk patients. We set out to explore EHCW’s perception after undergoing COVID-ACLS resuscitation training and address their anxiety of working in this pandemic. A qualitative case study using focused group discussion was conducted among EHCW who have undergone COVID-ACLS training. Five semi-structured questions exploring respondent’s confidence level, anxiety factors, areas of improvement for COVID-ACLS and if this COVID-ACLS training is sufficient. Inductive and deductive thematic analysis approach was done to analyse the result. 20 EHCW participated in this study. Out of 4 themes, 11 subthemes were identified based on the respondents. They were acquired new knowledge, self-precaution, method of delivery, concerns of self and family members, stigmatisation, insufficient protective methods, underappreciation, regular training sessions, other modalities for learning, course duration; and unsatisfactory reading material. New knowledge and self-precaution were noted to be an important aspect that boosts confidence among EHCW. The main factor that increased anxiety was safety issues and disease spreading to family members, colleagues, and society. In conclusion, COVID-ACLS training is able to boost EHCW confidence in resuscitating high-risk patients. Factors leading to anxiety among EHCW should also be addressed during this pandemic to ensure psychological welfare and mental health are not affected. Regular training and utilisation of other teaching modalities such as video are perceived as a helpful adjunct in boosting their confidence. The utilisation of new training approach should be explored in enhancing EHCW’s knowledge and confidence.
Intranodal palisaded myofibroblastoma: histopatologic and clinical review for clinicians and pathologists
Authors: PAYDAŞ Semra
Published: October 2021

Intranodal palisaded myofibroblastoma (IPM) is a kind of mesenchymal tumor with benign behaviour. The origin of this tumor is differentiated smooth muscle cells and myofibroblasts. This is a rare entity and differential diagnosis from malignant tumors is important for clinicians and pathologists. The etiology has not been explained adequately. Age range is between 2nd and 8th decades of the life and it is seen more frequently in males. Inguinal region is the most common localization but has been reported in other localizations including submandibular and retroperitoneal areas. Total excision of the tumor is the treatment in these cases. Recurrence is very rare and there is no report about metastasis. In conclusion IPM is a rare entity and it is commonly misdiagnosed as metastasis. Kaposi Sarcoma and schwannoma are the most common two spindle cell neoplasias. Be aware of this unique entity is important because wrong diagnosis causes dangerous management strategies.

This study aimed to explore deeply about the legal consequences of children born as a result of married by accident. The method used is formative juridical with the main reference Article 53 Compilation of Islamic Law, Article 250 of the Civil Code, Article 42 of the Marriage Law, and the Al-Qur’an namely Surat Al Isra ‘verse 32. The results of the study indicate that based on Compilation of Islamic Law, Article 250 of the Civil Code, and Article 42 of the Marriage Law, the legal status of a child resulting from a married by accident is a legitimate child, so it has the descent, inheritance rights, and guardianship rights of both parents. However, based on the Qur’an and the opinion of jumhur ulama, the legal status of a child resulting from the married by accident depends on the length of birth from the time of marriage. If more than six months old, the child’s status is legitimate so that he is entitled to both parents. If it is less than six months, then the status is an illegitimate child, so that he is only entitled to his mother from the descent, guardianship rights, and inheritance rights.
