Published: September 2021

Abstract
In order to better improve the efficiency of the concentrate filter press dehydration operation, this paper studies the mechanism and optimization methods of the filter press dehydration process. Machine learning models of RBF-OLS, RBF-GRNN and support vector regression (SVR) are constructed respectively, and Perform laboratory simulation and industrial simulation separately. SVR achieves the best accuracy in industrial simulation, the simulated mean relative error (MRE) of moisture and processing capacity are respectively 1.57% and 3.81%. Finally, a simulation model of the filter press dehydration process established by SVR, and the optimtical simulation results Obtained by optimization method based on control variables. The results show that the machine learning method of SVR and optimization methods based on control variables are applied to industry, which can not only ensure the stability of expected production indicators, but also shorten the filter press dehydration cycle to less than 85% of the original.

Authors: Ramadan Rania , Ismail Asmaa 
Published: September 2021

Abstract
This work studies the enhancement of the physical properties PVDF/PVC blend by adding ZnFe2O4 with different weight percent (from 0% up to 10%) as a nanofiller. The effect of ZnFe2O4 on behavior of PVDF/PVC was studied through XRD, FTIR, FESEM and UV-Visible spectroscopy. The PVDF/PVC/ 10% ZnFe2O4 nanocomposite film was represented the optimum sample. As it shows maximum crystallinity, roughness average (414 nm) and root mean square roughness (113nm) on another hand this sample has also the lowest value of energy band gap for direct and indirect transition. The removal efficiency of Cd(II) by using PVDF/PVC/ 10% ZnFe2O4 reached to about 50 % at pH 6 after 60min. the absorption mechanism as well as kinetics isotherm have been studied.
Quorum Sensing and Iron-Dependent Coordinated Control of Autoinducer-2 Production via Small RNA RyhB in Vibrio vulnificus

Published: September 2021

Abstract
Roles for the non-coding small RNA RyhB in quorum-sensing and iron-dependent gene modulation in the human pathogen V. vulnificus were assessed in this study. Both the quorum sensing master regulator SmcR and the Fur-iron complex were observed to bind to the region upstream of the non-coding small RNA RyhB gene to repress expression, which suggests that RyhB is associated with both quorum-sensing and iron-dependent signaling in this pathogen. We found that expression of LuxS, which is responsible for the biosynthesis of autoinducer-2 (AI-2), was higher in wild type than in a ryhB-deletion isotype. RyhB binds directly to the 5'-UTR of the luxS transcript to form a heteroduplex, which not only stabilizes LuxS mRNA but also disrupts the secondary structure that normally obscures the translational start codon and thereby allows translation of LuxS to begin. The binding of RyhB to LuxS mRNA requires the chaperone protein Hfq, which stabilizes RyhB. These results demonstrate that the small RNA RyhB is a key element associated with feedback control of AI-2 production, and that it inhibits quorum-sensing signaling in an iron-dependent manner. This study, taken together with previous studies, shows that iron availability and cell density signals are funneled to SmcR and RyhB, and that these regulators coordinate cognate signal pathways that result in the proper balance of protein expression in response to environmental conditions.
Transcriptome and Methylome Changes in Two Contrasting Mungbean Genotypes in Response to Drought Stress
Authors: Zhao Peilei , Ma Bao , Cai Chunmei , Xu Jihua 
Published: September 2021

Abstract
Background: Due to drought stress, the growth, distribution, and production of mungbean is severely restricted. Previous study combining physiological and transcriptomic data indicated different genotypes of mungbean exhibited variable responses when exposed to drought stress. Aside from the genetic variation, the modifications of environmentally induced epigenetics alterations on mungbean drought-stress responses were still elusive. Results: In this study, firstly, we compared the drought tolerance capacity at seedling stages by detecting physiological parameters in two contrasting genotypes wild mungbean 61 and cultivar 70 in response to drought stress. We found that wild mungbean 61 showed lower level of MDA and higher levels of SOD, POD, and CAT, suggesting wild mungbean 61 exhibited stronger drought resistances. Transcriptomic analysis indicated totally 2659 differentially expressed genes (DEGs) were detected when 61 compared with 70 (C61 vs C70), and the number increased to 3121 in the comparison of drought-treated 70 compared with drought-treated 61 (D70 vs D61). In addition, when drought-treated 61 and 70 were compared with their controls, the DEGs were 1117 and 185 respectively, with more down-regulated DEGs than up-regulated in D61 vs C61, which was opposite in D70 vs C70. Interestingly, corresponding to this, after drought stress, more hypermethylated differentially methylated regions (DMRs) in 61 were detected and more hypomethylated DMRs in 70 were detected. Further analysis suggested that the main variations between 61 and 70 existed in CHH methylation in promoter. Moreover, the preference of methylation status alterations in D60 vs C60 and D70 vs C70 also fell in CHH sequence context. Further analysis of the correlation between DMRs and DEGs indicated in both D61 vs C61 and D70 vs C70, the DMRs in gene body was significantly negatively correlated with DEGs. Conclusion: The physiological parameters in this research suggested that wild mungbean 61 was more resistant to drought stress, with more hypermethylated DMRs and less hypomethylated DMRs after drought stress, corresponding to more down-regulated DEGs than up-regulated DEGs. Among the three DNA methylation contexts CG, CHG, and CHH, asymmetric CHH contexts were more dynamic and prone to be altered by drought stress and genotypic variations.

Abstract
Background: Mitochondrial transplantation (MT) is a new technology developed in recent years, which injects healthy mitochondria directly into damaged tissues or blood vessels to play a therapeutic role. It has been studied in many animal models of various diseases, such as myocardial ischemia, cerebral stroke, liver and lung injury, and even has been successfully used in the treatment of childhood heart disease. MT can quickly improve tissue function within a few minutes after injection. This fast response is what is frequently questioned, for it is hard to understand how the whole mitochondria transport to the damaged sites, enter cells and function within such a short period of time. Are there any small molecules of mitochondrial component rather than the whole mitochondria that being responsible for the function of MT? To test this hypothesis, we established a much simple ultra-violet (UV)-irradiated HeLa cell model instead of the more complex animal models.Results: The results of colony formation, sulforhodamine B (SRB), and Hoechst 33342/PI double staining assay strongly indicated that MT exhibited a significant protective effect on UV irradiation damage. The UV irradiation-induced cell cycle arrest at S phase, apoptosis, mitochondrial membrane potential (MMP) decreasing, and the related apoptosis signalling factors p-IKKα, p-p65, I-κB and the activation of caspase3 were all reversed by MT treatments to some extent. Furthermore, mechanisms of MT were evaluated through comparing the effect of thermal inactivation, ultrasonic crushing, and repeated freezing and thawing treatments on MT function. The results denied the above hypothesis that mitochondrial component may function to MT, excluded the function of ATP, mtDNA and other small molecules, and indicated that the mitochondria structural integrity is essential.Conclusions: Our data support a potent anti-UV irradiation effect of MT, and structural integrity of mitochondria is critical for its function.

Published: September 2021

Abstract
Polyvinyl alcohol (PVA) decompose before melting, making it difficult for melt processing. This phenomenon limits the applications of PVA. Therefore, to widen the application of PVA, in the present work, the PVA films have been prepared by the flow casting method. And talc added as an inorganic nucleating agent to improve the crystallinity of PVA. The effects of talc on the crystallization behavior of PVA are tested by differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and successive self-nucleation annealing (SSA). The crystallization kinetics behavior of talc was is further studied by Mo Zhishen equation and Avrami equation. The results show that the addition of talc to the PVA film promotes its crystallization, and as the content of the nucleating agent increases, the crystallinity tends to increase, and the thickness of the wafer becomes uniform due to the increase of nucleation points. These results show that talc regulates the crystallization of PVA, improves the crystallinity and crystallization rate of PVA, and has a heterogeneous nucleation effect. PVA itself exhibits hydrophilicity because it contains large number of hydroxyl groups, and has good physical and chemical properties. In addition, the mechanical properties and water resistance have been further improved by improving the crystallinity of PVA, and the practicability of PVA film in actual production was improved.

Authors: Rebey Ahmed , Hamdi R. , Hammami B. 
Published: September 2021

Abstract
In this study, the electrodeposition technique has been used to deposit low concentrations of highly toxic lead (Pb) cations into a solution of nitrate at a constant potential of -1V on fluorine-doped tin oxide electrodes (FTO). Monitoring of the reaction was conducted with the assistance of a computerized potentiostat/galvanostat setup, in cyclic voltammetry and in situ chronoamperometry modes. X-ray diffraction, scanning electron microscopy, energy dispersive X-Ray, and ultraviolet-visible spectroscopy techniques were used to examine the crystal structure, morphology, and optical properties of the lead deposits, respectively. Pb regular micro-hexagons have been identified; their size and density were significantly influenced by the cationic precursor’s concentration. The correlation between the morphological and crystallographical structures of the electrodeposits was discussed. Based on chronoamperometric measurements, a mechanism for the growth of Pb deposits on FTO substrate has been proposed. Based on the reported results, electrodeposition processes of low heavy metals concentrations in contaminated water could be optimized using the eco-friendly electrodeposition technique.

Abstract
The optimal timing of endoscopy in patients with acute upper gastrointestinal bleeding (UGIB) remains controversial. In this study, we investigated the clinical outcomes of urgent endoscopy in patients with symptoms suggestive of UGIB compared with elective endoscopy.From January 2016 to December 2018, consecutive patients who visited the emergency department and underwent endoscopy for clinical manifestations of acute UGIB were eligible. Urgent endoscopy (within 6 hours) and elective endoscopy (after 6 hours) were defined as the time taken to perform endoscopy from presentation to the emergency department. The primary outcome was mortality rate within 30 days.A total of 572 patients were included in the analysis. Urgent endoscopy was performed in 490 patient. The 30–day mortality rate did not differ between the urgent endoscopy group and the elective endoscopy group. There was no difference regarding the recurrent bleeding rate, total amount of transfusion, and length of hospital stay in both groups. In multivariate analysis, age and the amount of transfusion were factors associated with mortality.Urgent endoscopy was not associated with lower 30–day mortality rate compared with elective endoscopy in patients with suspected of acute UGIB.

Published: September 2021

Abstract
Neuroendocrine tumours (NETs) originating from extrahepatic bile duct are an extremely rare entity. They are typically slow growing tumours with malignant potential. Commonly presenting as obstructive jaundice, preoperative clinico-radiologic differentiation between extrahepatic biliary tract neuroendocrine tumours and cholangiocarcinoma is difficult and the final diagnosis is usually established after surgical histopathology and immunohistochemistry examination. R0 resection offers the only curative option with good long term outcomes for Well differentiated NETs (grade1, grade2 and grade3) whilst the aggressive poorly differentiated Neuroendocrine Carcinoma (NEC) needs multimodality approach. We present our experience of management of four cases including three cases of grade II NET and one case of NEC undergoing surgical resection at a single centre with a short review of available literature.
Economics of Vertical Farming: Quantitative Decision Model and a Case Study for Different Markets in the USA
Authors: Moghimi Faraz , Asiabanpour Bahram 
Published: September 2021

Abstract
There are various problems associated with our conventional practice of farming. Agriculture is responsible for mass deforestation. The world is facing a water crisis, and farming is responsible for using 80% of its freshwater. Also, the prospect of global climate change is projecting a much riskier future for practices of conventional farming. One could argue that these alarming problems might someday be treated as more imminent as the population grows, less fertile land becomes available, and the effects of global climate change become more apparent. Vertical farming solves a lot of the mentioned issues associated with traditional farming by using considerably less water, requiring less land, and not relying on the environmental conditions whatsoever. However, vertical farming is also energy and labor intensive and can be quite expensive in some cases. This study works to quantitatively model and evaluate the economic prospect of vertical farming as a business venture in a competitive marketplace under different circumstances. A generalized quantitative framework to evaluate vertical farming with respect to traditional farming is developed. Then, the developed framework is employed for a case study to evaluate the merits of vertical farming in several locations around the US by measuring the relative profit and risk. The results quantify the value proposition of the practice in various conditions and help evaluate the current and future prospect the vertical farming industry.

Abstract
Biodiesel is one of the biomass materials or renewable energy, which is needed today to replace fuel from fossil energy, which can reduce global warming and has a high renewability cycle. Biodiesel is obtained from plants, so it is also known as biofuel. One type of biodiesel group is CME (Coconut Methyl Ester) which is biodiesel obtained from coconut oil as raw material. In this study, a synthesis of used coconut oil and methanol has been carried out with an organic catalyst based on coconut coir called the ASK catalyst. The results of transesterification have provided some important information, including: the yield are 15-19,5% after usage of the ASK catalyst consisting of amorphous phase and crystalline phase ClK0,8Na0,2, with the density and viscosity of products are 790-800 kg/m3 and 0,6-1 mm2/s. Yield data obtained are then used to build the kinetics equation. The equation is 𝑌 = 1 − e^(-k'tn), with the value of n = 1 and k' for temperatures of 50oC and 60oC were 0,20 and 0,21, respectively, and a minimum activation energy of Q = 1,1 kJ/mol, which can determine reaction time needed at a specified temperature to achieve a certain yield value.

Carson Ellis’ Bilderbuch Du Iz Tak? (2016) stellt eine besondere Herausforderung der Bilderbuchübersetzung dar, da der Schrifttext ausschließlich in einer fiktiven Sprache verfasst ist. Eine Übersetzung erscheint damit zwar auf den ersten Blick überflüssig. Eine nähere Untersuchung des Ausgangstextes legt jedoch vielfaltige intermodale, inter- und intralinguale Bezuge frei, die einerseits ein Feld der Polyvalenz entfalten und die Übersetzung erschweren, andererseits eine Übersetzung unumgänglich machen.

»Iz an Freuenschuh! An mirobelli Freuenschuh!«The Fictional Language in Carson Ellis’s Du Iz Tak? as a Field of Polyvalence and a Touchstone of Picturebook Translation
Carson Ellis’s award-winning picture book Du Iz Tak? is a special case of picturebook translation since the original text is written in an invented language. The comparative examination of the original and selected translations (German and Dutch) exposes the latent limits of picturebook translation. The written text in Du Iz Tak? consists exclusively of the direct speech of anthropomorphic insects. Reception of the work involves searching for clues in order to acquire the bug language. It is remarkable that, despite the invented nature of the bug language, different language editions of the work have been produced. Comments by the author and the publisher point out that the translation of the work was considered inevitable at an early stage, but it also represented a great challenge. The following two questions will be pursued in this article: Which intermodal interrelations within the original text determine the necessity of language-specific translations of Du Iz Tak? To what extent do the translations differ in their approach to this challenge? The semiosis of the bug language in Du Iz Tak? that demands translation is examined and the polyvalence of the text is discussed. A comparison of the original text with the two translations shows the translational shifts that are brought about by the notion of the single address in children’s literature. This article reveals the limits of transferability of this specific book as well as the general challenges of picturebook translation.

Theodor Storms Kindermärchen Der kleine Häwelmann, von dem Autor 1849 für seinen Sohn Hans verfasst und 1850 veröffentlicht, ist in seiner moralisch-komischen Form ein exemplarisches Exponat der Kinderliteratur des 19. Jahrhunderts. Gemäß der biedermeierlich gestimmten, belehrenden Funktion des Textes steht kindliche Allmachtsfantasie im Mittelpunkt des Geschehens. Die Haltung des ›Mehr-mehr‹ überschreitet indes die Grenzen der Moralerzählung. Entgegen der abschreckenden Funktion scheint vielmehr der kleine Häwelmann in der Verschränkung von Norm-Übertritt und Eskapismus ein ›modernes‹ Kind seiner Entstehungszeit zu sein und durchaus mit den Figuren des Struwwelpeters vergleichbar, die der Arzt und Kinderpsychiater Heinrich Hoffmann 1845 entworfen hat.

»Dreams Undoubtedly Belong to Reality«Dream Narratives About Childhood and for Children
The call for ›more!‹ is the force driving the protagonist of Theodor Storm’s literary fairy tale Der kleine Häwelmann (1850) on his imaginary journey through the night. This dream narrative is a combination of an exciting exploration of transcending borders with a hint of the moral tale, and can be seen as a model for the configuration of the dream motif in children’s and young adult literature. Although the dream narrative has a prominent place there, its investigation has hitherto almost exclusively taken place within the con­text of fantasy; the didactic functions of the dream, however, and the motif of the dream journey have largely been neglected. This article looks at how post­1945 children’s dream narratives explores representations of childhood. Benno Pludra’s Lütt Matten und die weiße Muschel (1963), a children’s story from the German Democratic Republic (GDR), is analysed and situated within the context of its literary system. Maurice Sendak’s Where the Wild Things Are (1963) is next considered in relation to Pludra’s text in order to pro­vide a contrastive view to a key text from the Western literary system. Both texts were hugely innovative for their time and respective systems, both use Storm’s Häwelmann as an intertextual anchor, and both, as this analysis shows, reveal recognisable societal discourses about childhood and cultural policies for children.

»Nun denkt der Traum hauptsächlich in Bildern« (Freud 2008, S. 51), stellt schon Sigmund Freud 1900 in seiner Traumdeutung fest. Träumen ist nach Freud eine visuelle Erfahrung, und als solche erscheint das Bilderbuch prädestiniert, Träume darzustellen. Was von dem Abgebildeten jedoch Traum ist und was nicht, lässt sich nicht immer eindeutig bestimmen.

Naturalistic Dreaming and Unreal WakingAspects of Dreaminess in Blexbolex’s Textless Picturebook The Holidays
This article examines narrative forms of dreaminess in Blexbolex’s textless picturebook The Holidays (2018; original title, Nos vacances, 2017; German edition, Unsere Ferien, 2018), which tells the story of a girl who, on a visit to her grandfather, encounters an anthropomorphised elephant – an encounter which is not harmonious. In two dream sequences, the desires and fears of the protagonist are revealed and put into perspective. In this article, these two sequences are examined within the contexts of the cultural history of dreams, and their narrative functions as analeptic reflections of daily events, on the one hand, and as proleptic epiphanies, on the other. Dream elements of the fictional waking world in the frame are also considered using Stefanie Kreuzer’s typology of narrative-structural characteristics and Christiane Solte-Gresser’s examination of the conventions pertaining to how dreams are presented in picturebooks. This article asks to what extent the alleged waking world itself can be categorised as a dream world. To answer this question, it focusses on the characters’ masking and identity confusion, the motif of the dream journey as well as the presentation of the elephant, whose naturalistic appearance in the dream sequences is in marked contrast to the unrealism with which the waking world is portrayed. The conclusion reflects on the particular suitability of textless picturebooks for presenting dreams.
