Authors: Sun Wenwen , Xia Huifang
Published: April 2023

To study the control optimization of conical interference connection system for large piston compressor, the reliability optimization and reliability optimization design of conical interference connection were systematically described. By using the proposed method, the maximum operating reliability can be obtained under the condition of constant interference joint size, namely, reliability optimization. Alternatively, the desired working reliability can be designed into the mating connection by optimizing parameters (combining size and interference), namely, reliability optimization design. Design value of 2.12 compression ratio is significantly higher than the unit level. As a result, the mid-stage exhaust temperature of the unit is as high as 124°C, and it is in high temperature operation state. It has been proved that conical interference connection is widely used in hydraulic transmission device because of its advantages of simple structure, reliable operation, and ability to bear certain impact load, reliable transmission torque than general connection, and convenient assembly and disassembly and has been proved to be reliable in practice.
The Temporal Relationships between the Pluscuamperfecto andmientras+ Imperfecto
Authors: Egetenmeyer Jakob
Published: April 2023

This paper analyzes the temporal relationship between a pluperfect verb in a main clause and a following subordinate clause introduced bymientras(‘while’) with an imperfect verb. The specific lexical and aspectual properties of the components lead to clashing expectations concerning the temporal relationship within the structure. The issues are three-fold. First, the subordinating conjunction lexically expresses the co-temporality of the subordinate clause with regard to another eventuality. Second, this may be possible when the pluperfect verb has an eventive reading, but what happens if it asserts a post-state? Third, the widely recognized discourse structural description (coming from DRT) of an imperfect verb is that its location time includes a previously introduced reference time. However, in traditional terms, the reference time involved in the meaning of a pluperfect verb is posterior to the event the pluperfect verb expresses. We address these issues and present a dataset collected from various corpora which underlines that the temporal relationships within the structure show a surprising variability. We discuss the different possibilities in depth, taking Aktionsart and subject reference into account. We also focus on the theoretical issue of the concept of reference time. On the basis of our data, and counter to the traditional approach, we argue that a temporal discourse structure should account for pluperfect verbs by means of secondary reference times.
Phonetic Context, Task Formality, Learner Level, and Orthographic Effects in L2 Spanish Palatal Obstruents
Authors: Tight Daniel G. , Vigil Donny A.
Published: April 2023

The current study investigates pronunciation of Spanish  and  by intermediate L1 English learners of L2 Spanish (N = 31). Third- (n = 17) and fifth-semester (n = 14) learners completed read-aloud and picture-naming tasks. Each contained items with  and  in stressed position after pause or nasal, and in unstressed intervocalic position. Recordings were made and analyzed with PRAAT. First, target segments were categorized based on spectrographic evidence (e.g., contour and intensity of formants, frication, burst) and aural review. Subsequently, intensity differences between the target segments and following vowel were computed. Results show minimal production of affricates/stops, even in contexts favoring them in some dialects (i.e., stressed position after pause, nasal). Nevertheless, both learner levels did produce significantly more constricted sounds in this context than in unstressed position between vowels, as measured by both analyses, with post-pausal position leading to the greatest constriction. Significant effects also emerged for letter, with  more frequently deleted or pronounced as a lateral, and for task, with the more formal task leading to greater constriction in the first analysis. No significant difference emerged based on learner level.

This classroom activity showcases how a free website and app, iNaturalist, can be used to introduce students to inquiry while also providing them with an opportunity to explore the outdoors. Inquiry-based approaches are known to have positive impacts on student learning. In addition to this, teaching scientific concepts outside may improve student learning gains while also highlighting the great biodiversity that exists right in their backyards. This project allows students to generate and investigate their own research questions based on their local communities. Students gather observations on the local organisms, utilizing iNaturalist, and ultimately create a presentation to share their findings. The instructor can modify the length of the project and the level of inquiry to fit the needs of a specific classroom. This project can be repeated several times to promote an appreciation of nature. Students can transform into true ecosystem explorers.
Voice and swallowing symptoms after thyroid surgery assessed using the ThyVoice online platform
Authors: Mihai Radu
Published: April 2023

Objective

The aim of this multicentre study was to investigate the progression of patient-reported outcomes after thyroid surgery, with emphasis on voice and swallowing difficulties.

Methods

An online platform was used to collect replies to standardised questionnaires (voice handicap index, VHI; voice-related quality of life, VrQoL; EAT-10) preoperatively and at 2–6 weeks and 3–6–12 months after surgery.

Results

A total of 236 patients were recruited from five centres that contributed with median of 11 cases (range 2–186 cases). Average symptoms scores showed voice changes lasting up to 3 months: VHI increased from 41 ± 15 (preop) to 48 ± 21 (6 weeks) and returned to 41 ± 15 at 6 months. Similarly, VrQoL increased from 12 ± 4 to 15 ± 6 and returned to 12 ± 4 (6 months). Severe voice changes (VHI > 60) were reported in 12% of patients preop, 22% at 2 weeks, 18% at 6 weeks, 13% at 3 months and 7% at 12 months. Only five patients with normal preoperative voice had persistent severe voice changes after 6–12 months. Those with severe voice changes at 2 weeks (median VHI 70.5, IQR 65–81) had significant improvement by 6 months (median VHI 54, IQR 39–65) (P < 0.001).

Swallowing assessment showed a median preop score of 0 (IQR 0–3) increasing to a median of 2 (IQR 0–8) at 2 weeks and normal values afterwards.

Conclusion

The ThyVoice online platform allows the assessment of patient-reported outcome measures in thyroid surgery. Voice morbidity appears to be more frequent than commonly reported, and this risk should the quoted during informed consent. Swallowing difficulties are mild but significant in the first 2 weeks.

Published: April 2023

Se evaluaron las propiedades reológicas y nutricionales en surimi de calamar gigante o pota (Dosidicus gigas) elaborado mediante lixiviación ácida-salina y la generación de un coloide sol con citrato sódico. La aplicación de 0.25, 1.27, 2.0, 3.0 y 7.0% de citrato sódico produjo un coloide sol a partir de las proteínas miofibrilares de calamar gigante. La adición hasta 3.0% de citrato sódico presenta una correlación lineal positiva con las propiedades de dureza y fuerza, y a partir de 2.0% se produce un incremento directamente proporcional con los módulos de elasticidad del gel. La adición de citrato como crioprotector en el producto no mejoró el efecto protector durante el almacenamiento a -20 °C por 72 horas. El reemplazo de NaCl por citrato sódico mejoró la textura del surimi, cambio que en términos de alimentación saludable contribuye con la limpieza de la etiqueta nutricional del producto al reducir su contenido de sodio a 57.8% y no superar el límite de 800 mg/100 g de alimento sólido.

In this work, we have studied the impact of various stages of cryopreservation by vitrification in ethylene glycolsucrose medium on plasma membranes adhesive properties of 8-cell murine embryos and their specific electrical conductivity. Embryos were divided into the following experimental groups: the control, group 1 (incubation in vitrification medium) and group 2 (complete cycle of cryopreservation). The embryo exposure to vitrification medium did not affect their ability to cell-to-cell adhesion. After a complete cycle of cryopreservation, no embryo adhesion was observed. Electrical conductivity of embryo membranes was determined using the pulsed conductometry. After incubation in vitrification medium, their resistance to electric pulse was shown to decrease, that was manifested in the phenomenon of irreversible electric breakdown. The average values of electrical conductivity varied within the following ranges: ((12.1 ± 1.5)...(55.5 ± 2.6)), ((28.7 ± 5.7)...(44.± 8.9)), ((31.0 ± 9.3)...(87.9 ± 26.1)) μS/cm in the control, groups 1 and 2, respectively. These findings may be explained by appearance of first structural disorders in lipid bilayer of embryo membranes even at the stage of their incubation in vitrification medium. The lack of adhesive properties of blastomeres after vitrification-warming testified to a damage to the membrane adhesion proteins.

Cerebrovascular pathology, especially acute cerebrovascular accident is among the most complicated issues in medicine. Therefore, the search for efficient ways to treat neurodegenerative diseases has still remained topical. In experimental model of ischemic stroke (IS), the impact of lyophilized and cryopreserved human cord blood leukoconcentrate (lHCBL and cHCBL, respectively) on immune system humoral and cell components has been comparatively studied. The ischemic stroke was simulated in 6-monthold Wistar rats by occlusion of the middle cerebral artery. The lHCBL and cHCBL were administered intraperitoneally at a dose of 0.5 ml of 5 × 106 cells in 6 hrs after surgery (occlusion). In blood serum, the populations and subpopulations of lymphocytes (CD3+, CD4+, CD8+, CD16+, CD4+CD25+), the content of total immunoglobulins and circulating immune complexes were determined. The experimental model of IS showed both lyophilization and cryopreservation of HCBL to ensure the preservation of immunomodulatory potential of cells, that was confirmed in vivo. An equivalent corrective effect of lHCBL and cHCBL on indices of immune system cell and humoral components during IS development has been established. The inclusion of lHCBL, as well as cHCBL and native HCBL in basic therapy of IS promoted a more rapid recovery of the immune system indices in animals.

O dizer como enquadre de guerra: masculinidades bélicas e letramentos pós-identitários no Brasil contemporâneo
Authors: Urzêda-Freitas Marco Túlio de
Published: April 2023

Resumo: O meu objetivo, neste artigo, é compartilhar uma reflexão inicial sobre um grupo de performances sociodiscursivas às quais tenho me referido como masculinidades bélicas, reflexão construída a partir de um diálogo indisciplinar com diferentes áreas do saber. Tendo como base a leitura crítica de duas performances e atendo-me ao contexto sociopolítico brasileiro atual, argumento que as masculinidades bélicas se caracterizam pelo engajamento dos sujeitos em práticas necrodiscursivas que (re)produzem enquadres de guerra em diferentes espaços sociais. Desse modo, sugiro o trabalho com letramentos pós-identitários como forma de estranhar textualmente os repertórios mobilizados por masculinidades bélicas, a fim de construir sentidos, performances e enquadres que desafiem o paradigma e a retórica da guerra, no Brasil contemporâneo.

In this research, we developed a unique power divider circuit construction that suppresses harmonic components while providing unequal power division ratios. In antenna arrays, a power divider is used to divide the power among the array's elements. Depending on the design, different power dividers have distinct properties. The purpose of this project was to create a design and examine a 1:8 unequal power divider for C-band applications that operates at 5.3 GHz. The prototype was built on a single board using a duroid RT5880 substrate with relative permittivity of 2.2 and thickness of 1.6 mm. A quarter-wave transformer was utilized to evenly distribute the entire incident power. This design involves adding an extra transmission line to the input side, which is known as a step-down transformer. The input impedance values were reduced and outstanding performance was achieved by using the step-down transformer. Advanced design system software was used in the simulations. The isolation network, which consisted of resisters between the transmission lines, was critical in implementing the radial layout styles and also improved the output port matching and port-to-port isolation. In the operating frequency range, the return loss parameters (S11–S99) and the isolation were greater than −17 and −37 dB, respectively. The intended structure is compact. The simulated results were in good agreement and demonstrated that all of the ports had matching impedance and the isolation matched the application's requirements.

Published: April 2023

Background. The several types of running in the team sports such as basketball, soccer and rugby, vary according to physical characteristics and sports. In particular, in the basketball the running is characterized by continuous acceleration and deceleration phases, which entails greater energy expenditure. This study aimed to assess the strength decrease of the lower limbs and energy expenditure at different running conditions (n=4) with/without the ball during Linear running and Shuttle run (180°) in two groups (male: n=15; female: n=15).
Materials and methods. Experimental approach required the following tests/devices: Squat Jump to assess the strength of the lower limbs before/after each test, and a portable Metabolimeter was used to assess the metabolic parameters. The T-test was used for independent samples and Two-way repeated measures ANOVA was used to assess the significant differences for each variable between each running conditions.
Results. Initial hypothesis has been confirmed, showing a significantly different strength decrease in different running conditions (Linear Running and Shuttle run with and without ball) and between the two teams considered (male and female). In addition, different energy expenditure between the two groups increases even more during the running with the ball compared to running without the ball.
Conclusions. The results of this study could be useful for coaches to optimize training with different training load related to gender and to the running conditions (with and without the ball), but also to optimize the work load of young players in relation to the abilities, skills and experiences of players.

Exploring European Citizens’ Resilience to Misinformation: Media Legitimacy and Media Trust as Predictive Variables
Authors: Rodríguez-Pérez Carlos , Canel María José
Published: April 2023

Building on the notion of an intangible resource, this research conceptualizes resilience as an intangible resource that can be ascribed to countries (governments and media) and explores its sources. After presenting the conceptual framework, the study uses cross-national comparable data from Eurobarometer to (a) determine whether a factor called “resilience to misinformation” can be composed of citizens’ attitudes and behaviors toward misinformation and be conceptualized and operationalized as an intangible asset, and (b) determine the extent to which other intangible assets regarding the media (legitimacy and trust) help predict resilience to misinformation. Based on statistical techniques, findings show that (a) it is possible to conceptualize “resilience to misinformation” as an intangible asset comprised of several items related to citizens’ awareness of misinformation, acknowledgment of the negative impact, and the development of skills to identify misinformation; (b) this intangible asset can be analyzed in relation to intangibles that derive from media performance, such as media legitimacy and trust in the media; and (c) media’s intangible assets seem to be more predictive of “resilience to misinformation” than sociodemographic variables. Based on the findings, this research proposes a conceptualization of “resilience to misinformation” as an intangible resource in the public sector. In addition, it highlights recommendations for the mainstream media on how to manage their intangible value while contributing to resilience to misinformation.

Objective: To study the antidiabetic effect of Withania Somnifera root powder (WSR) in Streptozotocin induced diabetic rats. Methods: Diabetes in rats were induced by injecting Streptozotocin intraperitoneally (45 mg/kg of body weight) to overnight fasting rats. Withania Somnifera root was given to group C (100 mg/ kg of body weight) and Pioglitazone to group D (20 mg/kg of body weight) orally for 4 weeks respectively. Blood glucose level, glycated Hb, insulin, protein tyrosine kinase activity and serum DPP-4 levels were measured. Results: Significant Improvement in body weight, glycemic profile, dyslipidemia and tyrosine kinase activity were observed in WSR treated rats at week 4 of the study compared to diabetic control rats. Blood glucose level, glycated Hb and Serum DPP4 levels, were also found to be decreased in WSR treated rats compared to diabetic control rats at the end of study. This is possibly due to augmented serum insulin levels and increased insulin sensitivity after treatment with WSR. Conclusion: The results from above study it was concluded that Withania Somnifera root powder has antidiabetic activity. Further study required to confirm the exact mechanism of action.
