Published: September 2023

Background
Bartonella spp. are fastidious bacteria frequently identified as the cause of blood culture-negative (BCN) endocarditis. However, Bartonella infections are difficult to diagnose in routine laboratory testing and their incidence is probably underestimated. We investigated the epidemiological and clinical features of Bartonella endocarditis cases diagnosed between 2009 and 2021 on Reunion Island (Southwest Indian Ocean).

Method
We retrospectively included all patients diagnosed with Bartonella endocarditis at Reunion Island University Hospital during this period. Endocarditis was diagnosed on the basis of microbiological findings, including serological tests (IFA) and PCR on cardiac valves, and the modified Duke criteria. We used then the multispacer typing (MST) method to genotype the available Bartonella strains.

Findings
We report 12 cases of B. quintana endocarditis on Reunion Island (83.3% in men, median patient age: 32 years). All the patients originated from the Comoros archipelago. The traditional risk factors for B. quintana infection (homelessness, alcoholism, exposure to body lice) were absent in all but two of the patients, who reported head louse infestations in childhood. Previous heart disease leading to valve dysfunction was recorded in 50% of patients. All patients underwent cardiac valve surgery and antimicrobial therapy with a regimen including doxycycline. All patients presented high C-reactive protein concentrations, anemia and negative blood cultures. The titer of IgG antibodies against Bartonella sp. exceeded 1:800 in 42% of patients. Specific PCR on cardiac valves confirmed the diagnosis of B. quintana endocarditis in all patients. Genotyping by the MST method was performed on four strains detected in preserved excised valves and was contributive for three, which displayed the MST6 genotype.

Conclusions
Bartonella quintana is an important cause of infective endocarditis in the Comoros archipelago and should be suspected in patients with mitral valve dysfunction and BCN from this area.
“Hasten the Revolution!”: Coalition-Building, Resistance, and Temporality in Leslie Feinberg's Fiction
Authors: Gaffin Austin 
Published: September 2023

Abstract
This article revisits Leslie Feinberg's pioneering Stone Butch Blues alongside hir lesser known second novel, Drag King Dreams. Through a prism of well-established queer theory and emerging trans scholarship, the author seeks to demonstrate how Feinberg's political vision retained its Marxist core while adapting with the times to confront new challenges presented by neoliberism, bio/necropolitics, and imperialist warfare. Living from the mid-twentieth century to the dawn of the twenty-first, Feinberg's life spanned from an era of industrial capitalism to the apotheosis of neoliberalism. Witnessing everything from pre-Stonewall queer culture to Gay Liberation and, eventually, homonormativity, Feinberg's political commitments remained remarkably consistent. Hir life and work were anchored by a critical class consciousnesses that, in a queer vein, destabilized identity in the formation of coalitional political work and, through a transgender/Marxist line of thought, rejected binary modes of gender altogether as coercive mechanisms of capitalism. Feinberg's project is thus at once historical, yet ever contemporary, and merits renewed attention and commitment in the twenty-first century.
Looking for Pauli, Pauli Murray's Trans Poetics
Authors: Awkward-Rich Cameron 
Published: September 2023

Abstract
Pauli Murray was a twentieth-century Black writer, priest, and legal thinker who has been, for the last two decades or so, the subject of a recovery project. As a result, Murray is now regarded as a crucial player in the history of civil rights litigation; in US feminist organizing and theology; and in Black feminist critique in relation to all of the above. Further, the recovery of Murray's contributions has coincided with the narration of Murray as someone who was (or might have been, in another time) trans. Following the lead of Isaac Julien's Looking for Langston (1989), and focusing on Murray's life and work as a poet, this meditative essay considers Pauli Murray as an enduring figure in and for a Black trans literary past.
SALAFI-INFLUENCERS: ANALYTICAL STUDY OF OF THE DISCOURSE OF NEO-SALAFI PREACHERS ON SOCIAL MEDIA
Authors: Abdulmajid Adib 
Published: September 2023

This discourse analytical study tackles the rise of
Neo-Salafism in the digital age. It constitutes an exploration of the discursive technics, strategies and practices employed by the new generation of Salafī preachers on social media. It strives to unveil the various discursive methods of indoctrination pursued by Salafi-influencers and the ends such strategies tend to serve. It involves an exploration of linguistic and contextual activities and seeks to identify explicit and implicit messages incorporated into the discourse of those young preachers. The main hypothesis upon which this study rests is that young preachers of Neo-Salafism resort to modified discursive technics that correspond to the age of digitalization and social media activism for the sake of ensuring a resounding impact among their addressees. These recipients represent a social incubator to the extremist Salafī ideology and a potential pool for a new wave of radicalization among the Muslim youth worldwide. A multi-dimensional methodological framework is employed to tackle the topic raised by this study. The data analyzed within the framework of this study consist of speeches and instructional communications by young Salafī preachers published through different social media platforms. Salafi-influencers seem to have developed a discourse characterized by certain manipulative strategies to communicate particular ideological messages and to indoctrinate recipients.

Abstract
Gallic acid is recognized as a notable bioactive compound among secondary polyphenolic metabolites. In the current study, gallic acid-enriched extracts were obtained from mango peels using different solvents (ethanol or water) via ultrasound-assisted extraction, and optimized yields were compared with the conventional extraction technique (decoction). Independent variables for the optimization through response surface methodology were ethanol concentration (0–60%), solvent ratio (10–50 mL/g), temperature (30–60℃), and time (10–30 min) for ethanolic extraction. However, extraction carried out by using water had extraction conditions of pH (2–8), solvent ratio (20–0 mL/g), extraction temperature (40–70℃), and time (30–60 min). The optimized yield of gallic acid obtained through ethanol was 5.75 ± 0.21 mg/g, whereas 3.14 ± 0.24 mg/g of gallic acid was quantified in extraction through water. The results were compared with the aforementioned conventional method of decoction, and it was concluded that the ethanolic extracts of mango peels showed the highest gallic acid yield and total flavonoid contents. The obtained extracts could be a potential source of polyphenolics, especially gallic acid, for use in nutraceuticals as well as in other food applications.
IP Law and Policy for the Data Economy in the EU
Authors: Leistner Matthias , Antoine Lucie 
Published: September 2023

Abstract
The current policy vision for Europe’s digital future centres around facilitating the availability of data by means of data access, sharing, and portability rights. In the existing legal framework, such rights are already foreseen in different legal instruments. In actual practice, however, (horizontal) data sharing is governed in the first place by contracts. Currently, well-established business practices and non-mandatory model contract terms are lacking. To reduce transaction costs and chilling effects in the sector, the main task would therefore be to provide a set of non-mandatory default rules or soft-law model contracts. The database maker’s sui generis right or trade secrets protection, mainstays of this area, have the potential to aggravate access problems and hamper efficient access and portability regimes. While the Trade Secrets Directive as a very modern and necessarily flexible instrument, on principle, is rather well-equipped for achieving balanced results, the Database Directive is in imminent need of reform, in particular as even the Data Act Proposal leaves many issues of the database sui generis right unsolved.

Published: September 2023

AbstractThis study is part of a series of studies aimed at measuring the thermophysical properties of molten phase change material-type metallic thermal energy storage materials near 873 K (600°C). The target material is Al–Si based alloys. First, as a feasibility study, density measurements of the molten state of three Al–Si binary alloys (Al–12.2Si, Al–50Si and Al–90Si in atomic%) were performed. A highly accurate non-contact density measurement method based on the static magnetic field superposition electromagnetic levitation (EML) method was employed as the density measurement method. The validity of this experimental method was confirmed, and density of molten Al–Si base alloys (ADC12 and Al–5.9mass%Si–1.6mass%Fe) were measured as a function of temperature with an expanded uncertainty of 1.2%. In addition, the surface tension of the alloys was measured by the droplet oscillation method using the EML technique. The surface tension was successfully obtained as a function of temperature with expanded uncertainty of 2.3%.
Intelligent control system for industrial robots based on multi-source data fusion
Authors: Zhang Yang 
Published: September 2023

Abstract
Industrialization has advanced quickly, bringing intelligent production and manufacturing into people’s daily lives, but it has also created a number of issues with the ability of intelligent control systems for industrial robots. As a result, a study has been conducted on the use of multi-source data fusion methods in the mechanical industry. First, the research analyzes and discusses the existing research at home and abroad. Then, a robot intelligent control system based on multi-source fusion method is proposed, which combines multi-source data fusion with principal component analysis to better fuse data of multiple control periods; In the process, the experimental results are dynamically evaluated, and the performance of the proposed method is compared with other fusion methods. The results of the study showed that the confidence values and recognition correctness of the intelligent control system under the proposed method were superior compared to the Yu, Murphy, and Deng methods. Applying the method to the comparison of real-time and historical data values, it is found that the predicted data under the proposed method fits better with the actual data values, and the fit can be as high as 0.9945. The dynamic evaluation analysis of single and multi-factor in the simulation stage demonstrates that the control ability in the training samples of 0–100 is often better than the actual results, and the best evaluation results may be obtained at the sample size of 50 per batch. The aforementioned findings demonstrated that the multi-data fusion method that was suggested had a high degree of viability and accuracy for the intelligent control system of industrial robots and could offer a fresh line of enquiry for the advancement and development of the mechanical industrialization field.
Effect of carbon nanotubes on microstructure and mechanical properties of TiZrVMnCu–Er high entropy alloy composites
Authors: Wang Xing , Jiang Xiaosong , Chen Jinmei , Sun Hongliang 
Published: September 2023

Abstract
To improve the ductility and toughness of refractory high entropy alloy (Ti, Zr, V), Mn and Cu were added to form TiZrVMnCu high entropy alloy with soft and hard phases. Carbon nanotubes (CNTs) and Er were introduced to fabricated composites with high strength and ductility. The relative density, microhardness, and compressive strength of TiZrVMnCu–Er–CNTs composites were in direct proportional to CNTs content from 0 to 0.5 wt%. The composite with 0.5 wt% CNTs has the highest hardness (634.4 HV) and strength (1720.7 MPa), and the strain variable is 14.3 %. The fracture toughness of the composites was improved by the crack bridging mechanism and crack deflection mechanism induced by adding CNTs. The fine grain, second phase strengthening mechanism, and the load transfer mechanism induced by CNTs improved the strength and hardness of the composites. Er can achieve solid solution strengthening or play a role in the second phase and fine grain strengthening.
Fatigue performance of laser cut carbon fiber-reinforced epoxy and polyamide 6 considering specimen width
Authors: Gerdes Lars , Mrzljak Selim , Keuntje Jan , Wippo Verena , Jaeschke Peter , Walther Frank 
Published: September 2023

Abstract
Since the development of laser systems technology led to a significantly decreased energy input by pulsing, laser cutting became a noteworthy method for cutting fiber-reinforced polymers. Despite the occurrence of heat introduction and heat-affected zones (HAZ), there are advantages regarding processing speed and maneuverability. Within this work, the influence of two cutting parameters (low (A) and high heat introduction (B)) on the fatigue properties of carbon fiber–reinforced epoxy and polyamide 6 were investigated. At the same time, micro waterjet cut specimens were added as a reference. In doing so, laminates were cut to different specimen widths and orientations. Multiple amplitude tests were performed with strain and temperature measurements. The results show an influence of specimen width on fatigue lifetime for the epoxy system, but not in polyamide 6. The 45° specimens for both CFR-EP and CFR-PA6 showed a decreased lifetime when cut with parameters B. However, these findings do not apply to 0° specimens, since parameters A lead to a smaller lifetime for CFR-EP, and no influence was found for CFR-PA6. Furthermore, no clear HAZ could be identified for A. Since there is a decrease in lifetime for CFR-EP, the necessity of applying further methods for HAZ detection is described.

Schutz des Wettbewerbs vor systemischer Wirtschaftsmacht durch den Digital Markets Act – Zur Abgrenzung von Wettbewerbs- und Regulierungsrecht
Authors: Mohr Jochen 
Published: September 2023

Zusammenfassung
Der Digital Markets Act ist ein zentraler Bestandteil des Rechts gegen Wettbewerbsbeschränkungen im 21. Jahrhundert. Mit der Anknüpfung an den Torwächter-Status reagiert der Verordnungsgeber auf neuartige Erscheinungsformen systemischer Wirtschaftsmacht in digitalen Ökosystemen. Die sich hieraus ergebenden Wettbewerbsprobleme werden mittels der Art. 5 bis 7 DMA in ihrer Ausgestaltung als äußere Grenznormen adressiert, die den Wettbewerb punktuell vor bestimmten Behinderungs- und Ausbeutungspraktiken von Torwächtern schützen. Die praktische Wirksamkeit der in Art. 5 bis 7 DMA enthaltenen Verpflichtungen wird durch das Umgehungsverbot in Art. 13 DMA gesichert, das damit ebenfalls als äußere Grenznorm zum Schutz des Wettbewerbs anzusehen ist. Die Zuordnung des Digital Markets Act zum Wettbewerbsrecht gibt dazu Anlass, die Rechtsgrundlage des Art. 114 AEUV kritisch zu hinterfragen, da sie vom Verordnungsgeber aus kompetenziellen und nicht aus inhaltlichen Erwägungen gewählt wurde.

Comparison of Early Versus Late Urethral Catheter Removal After Transurethral Resection of the Prostate in Patients with Benign Prostate Hyperplasia
Authors: ŞENOĞLU Yusuf , TEKİN Ali , YILDIRIM Olcay , BABA Dursun , YÜKSEL Alpaslan 
Published: September 2023

Objective: Transurethral resection of the prostate (TURP) is considered the standard in the surgical therapy of lower urinary tract symptoms related to benign prostate hyperplasia (BPH). However, there is no consensus on the timing of catheter removal. In this study, we aimed to compare the long-term effects of early and delayed removal of urethral catheters who underwent TURP.
Methods: We prospectively analyzed a total of 91 patients who underwent TURP. Patients were randomized into two groups; the early (postop 1st-2nd days) and delayed (7th day) removal of the urethral catheter. After the surgery in 1, 3, and 6th months, we evaluated all patients regarding treatment success. In addition, international prostate symptom score (IPSS), quality of life (QoL), maximum flow rate, postvoid residual urine volume, and morbidities (hematuria, infection, urethral stricture, irritative symptoms, need for re-operation) were assessed at all visits.
Results: After TURP, there was no statistical difference in urodynamic parameters, complications, IPSS, and QoL in both groups. Only in the 3rd-month, the maximum flow rate was higher in favor of the early group. Despite similar results in both groups, strictures occurred earlier in the early group than delayed group (respectively 1 and 3 months).
Conclusion: These results suggest that there are no differences in efficacy and complications in groups of early or delayed urethral catheter removal after TURP. The results of long-term studies with large series should be awaited to reach a more definite conclusion. We have tried to shed light on a topic without consensus on the time of urethral catheterization after TURP.
Teaching reading and writing skills to pre-intermediate level students
Authors: POLATOVA Sarvinoz 
Published: September 2023

Abstract
In this article there was revealed the skills for pre-intermediate level English learners. Here there was discussed about how to make reading and writing skills shorter and easier for learning. The reason is that many English language learners face a very big problem in the writing part. In this research there was discussed basic knowledge on how to quickly understand and smooth the translation in the reading sections. Reading is important because it develops mind and gives excessive knowledge and lessons of life. It helps you understand the world around you better and keeps your mind active, enhances creative ability. Reading improves vocabulary and develops communication skills, while writing is important in its own right; the evidence clearly shows that writing supports reading and reading development. They also are vital ways of improving reading skills overall. Reading and writing are academic skills, to be sure. It is a process of organizing ideas and creativity through text. It is useful for all skill levels, from children to published authors, to develop an authentic, creative work. It breaks the act of writing into manageable steps that can be taken over a period of time, rather than all at once. Readers need a conclusion to remind them of essay's main points and give a feeling of closure to the essay. A strong conclusion: sums up the main point of your paper. Ends with a "takeaway" for readers: what lesson can be learned from your main point, or what should be done in the future? When the words are understood and transcend the pages to become thoughts and ideas then you are truly reading. Comprehension therefore is the capacity for understanding those thoughts and ideas. Conclusions that do not summarize often don't sound like conclusions. Readers expect that a writer will sum up at the beginning of a conclusion, at least for a sentence or two, and may not recognize a conclusion that doesn't open this way. Also, summarizing the main point reminds readers of the most important ideas in the essay as it comes to an end. These guide strategies are useful for all English language learners. However, by following these tips, pre-intermediate students will feel that their reading and writing skills have increased significantly.
