Fracture toughness evaluation of zeolite/polyurethane-filled woven panels
Authors: Safari Hamid , Karevan Mehdi , Nahvi Hassan
Published: April 2023

Recently, due to their extraordinary strength-to-weight ratio and multi-functional applications, three-dimensional woven fiberglass sandwich structures have become a well-received topic by researchers and manufacturers. Nevertheless, using light and foam absorber materials as injected fillers within sandwich cores can improve their overall mechanical performance and, in particular, their fracture toughness behavior. This study evaluates the fracture toughness of three-dimensional woven fiberglass sandwich panels filled with natural nano-structured zeolite/polyurethane foams injected between their parallel panels. The Single-Edge Notched Bend test was carried out to understand the effect of the injected foam on the mode-I fracture toughness response. It is demonstrated that the polyurethane foam reinforced with natural nano-structured zeolite particles highly improved the fracture toughness of sandwich core panels. It was found that the presence of vertical glass yarns within the sandwich panel gallery resulted in a significantly higher toughness compared with typical sandwich panels of no reinforcing vertical columns confirmed by the crack propagation and observed failure mode. The SEM and EDX analyses were used to better understand the correlations amongst the specimen morphology, the cracks behavior, and the toughness exhibited by the fabricated specimens.
Hot workability characteristics of two A335 P92 steels for power plant application: A comparative study
Authors: Obiko J.O. , Chow L.H. , Whitefield D.J. , Bodunrin M.O.
Published: April 2023

The article reports on the workability of two P92 steels having a chromium content of 8.29 and 9.48 wt%. Constitutive equations were used to calculate material parameters describing the hot deformation flow stress. Hot deformation tests were conducted using the Gleeble® 3500 thermomechanical facility. Test conditions were: temperature of 850-1000°C and strain rate of 0.1-10s-1 to a strain of 0.5. The flow stress curve results show that dynamic recovery was the only softening mechanism. A comparative study of the two steels revealed that Cr content had a marginal significance on the flow stress behaviour. Constitutive analysis results of the material parameters were: a stress exponent of 9.0 (P92-A), and 11.0 (P92-B), while the activation energy was 369 kJmol-1 (P92-A), and 472 kJmol-1 (P92-B). A brief explanation of the material parameter results is in this article. A flow stress model was developed to predict the flow stress behaviour of the two P92 steels investigated. The results show that the model accurately predicts the flow stress at all the deformation conditions applied. The statistical parameters showed a good correlation between the predicted and the experimental data. Therefore, this model can be used to develop metal forming schedules for industrial applications.
Experimental analysis of bolted, bonded, and hybrid spliced joint connections in glass fiber reinforced polymer short column
Authors: Srujan M. J. , Srikanth Seelam
Published: April 2023

Glass Fiber Reinforced Polymer (GFRP) is a polymer composite material used in lightweight structures. This study provides insight into achieving robust GFRP H-section short-column spliced connections using bonded, bolted, and hybrid connections. The design specifications for steel splicing connections are based on BS EN 1990 and BS EN 1991 guidelines. Based on the samples subjected to axial loading, factors such as compressive strength, bonding and bearing resistance, compression behavior of the connection, and failure modes of the structure are investigated. The study includes the behavioral characteristics and results of 25 GFRP H-section Spliced connections, with each H-section measuring 152 x 72 x 6.4 mm and standing 350 mm in height. This study also examines the behavior of a composite splice joint made up of steel cover plates and steel bolts that are used to create an ideal non-bearing spliced connection. This model is used to compare to the other models to understand the behavior of spliced joints designed with GFRP cover plates. This paper holds design specifications of connections that have displayed compressive strengths of 82.35 %, 89.82 %, and 92.83 % compared to that of an un-cut GFRP H-section subjected to axial loading.
The effect of hardness matching of rail/wheel materials on wear rate of railway wheel
Authors: Yenealem Hewan Getachew , Redda Daniel T. , Mohammedseid Awel
Published: April 2023

There is no rationalization for a certainty that harder wheels or rails will result in an increase in wear of the opposite side of the wheel/rail interface. This research investigated how the wear of wheel material changes when the hardness of the opposing pair is varied. Three Rail/wheel material matches; normalized UIC50 kg/m and S1002 wheel profile (Rail/wheel material 1), normalized UIC60 kg/m and whole heat treated S1002 wheel profile (Rail/wheel material 2) and rim heat treated UIC60 kg/m and whole heat treated S1002 wheel profile (Rail/wheel material 3) has been investigated using multi-body simulation software (SIMPACK) and MATLAB programming. For validation, as an experimental advantage, the wear depths measured on the wheel tread wear of the end vehicle of LRT for mileage of 50,000 km are compared to the results of numerical simulation performed. As a result, the estimated total tread wear amount after a mileage of 50,000 km is 4% larger than the experimental one. That is indeed a very good result considering that either component of the wheel wear prediction model used is neither adjustment nor calibration. From the three rail/wheel matches, Rail/wheel material 3 found to be the better material match that could resist wear significantly considering material hardness as important criteria for comparison. The study could remark that, despite the fact both wheel and rail material hardness could affect the wear performance in respected positive ways, most significant improvements are attained by improving the rail material hardness ahead of wheel material.

Published: April 2023

The article analyzes the stress-strain state in the zone of plastic deformation during special caliber rolling. The principle of caliber rolling technology is described, which makes it possible to combine shear and compression deformations in the cross-section of metals, alloys, and metal-matrix composites. The analysis results of stresses and strains during shear rolling in a diamond pass, which included compressive strains that had not been considered in previous studies, revealed that localization or point inversion of stresses and strains is observed in the plastic deformation zone. Stress and strain are localized along the minor and major diagonals of the diamond pass.
Explaining Variations in Cryptocurrency Ownership: A Cross-country Study
Authors: Lee Sang , Labasse Gavin , Gardner Lara , Vicknair Jamie
Published: April 2023

This study investigates how cryptocurrency ownership varies across countries using a set of variables that reflect a country's overall economic circumstances and long-term outlook. Despite the nascent stage of the cryptocurrency market and the concomitant deficiency of the data on cryptocurrency, a multiple linear regression is fitted as an incipient step towards more advanced future studies. Our empirical findings show that cryptocurrency ownership is more likely to grow in a country with (1) a high human capital stock such as citizens' health and education and (2) a rich endowment of legal property rights. It was also inferred from the regression results that cryptocurrency could be an effective hedge against inflation to some extent.

Published: April 2023

The quality and consistency of historical temperature and precipitation records are extremely important to researchers who study water resources, hydrological processes, and climate change. In this regard, Homogeneity tests are helpful tools for managing the accuracy and consistency of the data. In this study, the homogeneity of long-term annual and seasonal precipitation and temperature records obtained from five meteorological stations located in Van, Turkey, is examined using Standard Normal Homogeneity (SNHT), Pettitt (PT), Buishand Range (BR), and Cumulative Deviation (CD) tests at a significance level of 0.05. Finally, change-points were determined for each station where the homogeneity was disturbed. As a result of the study, there is mostly homogeneity in the precipitation data, and the homogeneity in the temperature data is deteriorated. The results of this study constitute a source of information in terms of the reliability of the meteorological data series. As a result, the reliability of the data should be questioned in the hydrological studies to be carried out in the Van region and the data should be made reliable in the projects to be carried out.

Având intenția de a defini conceptul și de a trasa o traiectorie pentru țara lor, diferiți cercetători chinezi de la marile universități din China, preocupați de problematica soft power, au publicat numeroase articole, în care au descris în mod sistematic perspectiva Chinei asupra acestui concept și poziția în care țara lor se plasa la începutul anilor 2000. Parcurgând sursele chineze și comparându-le cu noțiunile generale despre soft power, prezentate de Joseph Nye, putem afirma faptul că asistăm, în China, la un nou proces de asimilare și adaptare, în conformitate cu politica țării, a unei teorii care nu provine din spațiul asiatic. Prezentul articol își propune să ilustreze modul în care China definește soft power și felul în care aceasta a pus în aplicare acest nou instrument al noii diplomații prin analizarea materialelor de specialitate, apărute în China în perioada 2005-2017.
Conflictul ostroavelor. Incidente la frontiera româno-bulgară (1879-1908)
Authors: NICULAE Daniel Silviu
Published: April 2023

Linia de frontieră a unui stat reprezintă delimitarea suprafeţei teritoriale, maritime, fluviale şi aeriene, în interiorul căreia îşi exercită suveranitatea exclusivă şi deplină, asigurând naţiunii sale dreptul la autodeterminare. Astăzi,frontiera statelor membre ale Uniunii Europene este un punct de trecere controlabil, liber, însă pe fondul crizei migraţiei din ultimii ani, curentul instituirii unei graniţe vizibile, eficiente şi operaţionale în rolul ei de control al fluxului de populaţie şi comercial este tot mai puternic, amintind de sistemul westfalian, instituit în secolul al XVII-lea, odată cu apariţia statelor moderne. În Europa secolelor XIX şi XX, conflictele dintre state au avut ca efect modificarea frontierelor teritoriale consemnate în tratatele bilaterale. Articolul de faţă dezbate efectele juridice ale Tratatului de la Berlin din anul 1878, când a fost trasată frontiera terestră dintre România şi Bulgaria. Stabilirea, la 2 septembrie 1879, a frontierei fluviale româno-bulgare pe talveg de către membrii Comisiei europene pentru delimitarea frontierei româno-bulgare ignora prevederile articolului 2 al Tratatului de la Berlin, fapt pentru care au avut loc dese incidente la graniţa de sud, care au generat, la sfârşitul secolului al XIX-lea şi începutul secolului al XX-lea, o stare tensionată din punct de vedere politic, diplomatic şi militar la graniţa de sud a României.
Militarii, protecția datelor personale și jurnalismul detractor. Legislație și jurisprudență (partea întâi)

Puține drepturi fundamentale sunt absolute. Aceasta înseamnă că exercițiul celorlalte, care sunt relative, poate fi, uneori, restrâns, îngrădit, limitat. Dreptul la protecția datelor cu caracter personal intră în această ultimă categorie; această realitate juridică trebuie luată în considerare, în raport cu funcția pe care acest drept o îndeplinește în societate și echilibrat cu alte drepturi fundamentale, în conformitate cu principiul proporționalității. Am văzut și vom vedea, în continuare, că dreptul la protecția datelor personale și cel la o viață privată pot intra în divergență, coliziune, litigiu cu libertatea de exprimare, un alt drept fundamental, care are două ramuri, libertatea de a informa și cea de a fi informat. În această privință, ne-au stabilit norme Curtea Europeană a Drepturilor Omului și Curtea de Justiție a Uniunii Europene
Securitatea personalului ONU în misiunile și operațiile de pace
Authors: MANGA Mariu Vasile
Published: April 2023

Personalul organizațiilor și organismelor internaționale este expus nu numai la situații de conflict existente în state în colaps în care se desfășoară misiuni și operații de pace, dar și la o nouă gamă de riscuri și amenințări, rezultate dintr-un tablou securitar complex, dominat de noi mutații conceptuale și de un ritm alert privind dezvoltarea tehnologică. Trendul victimelor în rândul angajaților Organizației Națiunilor Unite (ONU) în ultimii ani rămâne ridicat, ceea ce ne arată că, în continuare, violența armată constituie un fenomen amplu în zonele misiunilor și operațiilor de pace. Procesul de reducere a riscului este complex și se bazează pe nevoia de realizare a unei evaluări permanente și de o manieră adaptativă a situației de securitate, precum și pe o corelare continuă a acestor riscuri cu nivelul de capabilități avute la dispoziție
The Validity of a Novel Low-Cost, Wearable Physical Activity Monitor in a Laboratory Setting
Authors: Newton Andrew , Glickman Ellen , Barkley Jacob
Published: April 2023

Introduction: Wearable physical activity monitors are popular and may provide a more accurate data than subjective methods. The present study assessed the validity of a novel, low-cost wearable physical activity monitor (Movband 3) relative to established measures.
Methods: Participants (N = 19) completed four treadmill stages (1.5, 3.0, 4.0, 6.0 MPH) while wearing the Movband 3 and the validated Actigraph GT1M monitor. Oxygen consumption (VO2 ml/kg/min) and heart rate (beats/min) were recorded. The relationship between Movband data and established measures was assessed via Pearson’s correlations. Tests of agreement were performed for actual and Movband miles traveled.  
Results: There were large, positive, significant (p < 0.001) effect sizes for the associations between Movband counts and Actigraph counts (r = 0.72), VO2 (r = 0.59), and heart rate (r = 0.63). There was also a large, positive, significant (p < 0.001) association between actual and Movband miles (r = 0.97). However, the difference (Δ) between Movband and actual miles was greater than a null hypothesis of zero (∆ = 0.77 ± 0.45 miles or 31.8%, t = 7.4, p < 0.001).
Conclusion: While there was evidence to support the validity of the Movband 3 for the assessment of physical activity intensity this device did not provide an accurate measure of miles traveled.

Roads play a crucial role in fostering economic growth and providing social advantages in every nation. However, over time, road infrastructure can become outdated. According to studies conducted by World Highways, a road may seem to be in good condition on the surface while hiding a severe issue beneath. As a result, periodic maintenance, repairs, or modernization may be necessary for road structures. The primary purpose of this project was to investigate the effects of permeability on road base materials by removing particles and restoring strength through stabilization with bitumen. Optimum grade 60/70 bitumen was used in compliance with Malaysia JKR specifications to create a realistic case scenario. The formulation excluded open-graded road base material with particles smaller than 1.18 mm or 2.0 mm, and bitumen stabilization levels of 0%, 2%, 2.5%, and 3% were implemented to reduce the decrease in mechanical strength. The mechanical strength was determined using the California Bearing Ratio (CBR) test, while a Constant Head Method Permeability test was conducted to identify the optimal design mix with the maximum achievable permeability coefficient. The results showed that bitumen stabilization increased the mechanical strength of the road base material, with the highest result compensating for the drop by 8.7%. With open-graded road base material, the permeability can be increased by up to 17.2%. Therefore, open-graded road foundation material with bitumen as a binder for stabilization can be used in the construction of pavements in Malaysia, an area with relatively high rainfall intensity.

Research on the Dynamics of the Formation of “Internet Celebrity Politics” from the Perspective of Semiotics
Authors: DENG Shiqin
Published: April 2023

With the development of Internet technology, online popularity politics is born. Especially in the national and regional political elections, online politics is mainly presented in the form of online politicians. Online popularity is the most prominent feature of politicians. How did online popularity politics come into being? Based on the semiotic theory, this paper points out that the effective interaction and operation among the media, speech acts and audience objects constitute the mechanism for the formation of online celebrity politics in the Internet era. Specifically, politicians’ exaggerated body behavior, novel language and rich expressions are regarded as personalized expressions with labels. With the help of the Internet media, politicians’ images are constantly constructed and stereotyped in personalized symbolic expressions through the two paths of political election disenchantment and personal identity labeling. Politicians take this opportunity to win the support rate and attention of the public and finally get votes.
A Study of Bloom Narrative in Elizabeth Gaskell’s Fiction
Authors: LI Hongqing
Published: April 2023

Elizabeth Gaskell was an influential female writer in the 19th-century English literary arena. The courtship and marriage narrative almost ran through all her fiction. This paper argues that Linnaeus’ botanical system provided discourse support for her courtship and marriage narrative. From the late 18th century to the 19th century, as Linnaean classification popularized, the term “flower”(plants’sexual organ) became more commonly used as “bloom,” referring to “potential sex.” Linnaeus termed the sexual reproduction of a flower marriage, linking “sex” to marriage and rendering the natural (illegitimate) meaning of sex socialized (legitimate). In this cultural context, Gaskell introduced “bloom narrative” into her works, using “bloom” and its cognate words “garden, landscape, etc.” to represent the sexual attraction of blooming girls and reproduce their marriage and courtship, and using botanical language as a metaphor for the process of female socialization to explore the possible social consequences. It is worth noting that Linnaeus divided plants into public marriage and clandestine marriage according to whether flowers could be seen by the naked eye. Gaskell not only reproduced the sexual attraction in public marriages as traditional writers as Austen did but also discussed the sexual attraction in clandestine marriages. In North and South, Linnaeus’s “public marriage” category was represented. Gaskell linked sexual attraction to marriage and enabled the heroine to successfully exercise her feminine influence, and thus facilitate labor-capital reconciliation, demonstrating her strong desire to bridge the gap between the public and private spheres. In Ruth, by separating sexual attraction (bloom) from marriage and treating the sexual behavior of the hero and heroine as Linnaeus’s “clandestine marriage,) Gaskell presented both the heroine’s sexual charm and her innocence, thus effectively challenging the traditional narrative of depraved women. The bloom narrative meets Gaskell’s multiple requirements of conforming to secular moral values, achieving realistic effects as well as participating in the discussion of gender topics, which reveals her diverse and cross-boundary artistic creation concept.
Pilgrimage and Return: A Preliminary Study on the Prototype of James Gunn’s Transcendental Novels
Authors: WANG Fei
Published: April 2023

Archetype is the path to the unconscious, myth is one of the forms of archetype in ancient times, and science fiction is a modern myth. What science fiction and myth have in common is the reflection on the current order and the imagination of the unknown world (the dream about the unknown). James Gunn’s “Transcendent”, science fiction series is a contemporary re-writing of Campbell’s heroic model, as well as a re-creation of the pilgrimage narrative model in Chaucer’s Canterbury Tales, with Jung’s immutable archetype lurking behind it. This paper attempts to explore the prototype and mechanism created by James Gunn through the analysis of the hero mode and pilgrimage journey in this series of science fiction. The driving force behind the pilgrimage mode and hero mode is the process of subverting people’s spirit of having no support and longing for direction based on the development of science and technology and trying to find the right answer. It is a manifestation of the human panic at the loss of direction and the growing sense of impending doom.
From Blurring to Transcending: Emily’s Epiphany and Shaping of Community of Shared Future in Caryl Phillips’s Cambridge
Authors: HE Na
Published: April 2023

Caryl Phillips (1958-), a leading novelist in Contemporary British literature is acclaimed as one of the best-known and most talented Black British writers of his West Indian generation. Cambridge, his fourth novel and regarded as the most Caribbean and universal novel, has garnered flowering acclaims at home and abroad since publication in 1991. The article elaborates on the implications of Emily’s epiphany from muti-perspectives framed within the framework of epiphany. Through a systematic study of Emily’s epiphany, it is to point out the refreshing implications, namely, the affinities between the colonizers and the colonized, blur the epistemic boundaries and further indicate that through blurring and transcending boundaries, mutual empathy and telepathy could be evoked among people from different social hierarchies with a community of shared future for mankind shaped.
