Large Break Loss-of-Coolant-Accident (LBLOCA) in a Zion-like plant was simulated using the MAAP code. The plant responses during the accident were investigated for conventional Zr cladding and two ATF cladding materials, SiC and FeCrAl. The maximum cladding temperature increase was delayed by replacing Zr with SiC or FeCrAl, which is considered to be due to smaller oxidation energies of the two ATF cladding materials. The gap pressure causing tube burst was increased at slower rates with SiC and FeCrAl, indicating that tube burst can be delayed as well. The tube burst behavior of the materials will be studied at the next stage.
As technological advancements occur in the field of manufacturing, 3D printing has been increasingly growing and becoming more attractive to manufacturers. Additive manufacturing (AM) has enabled the manufacturing of intricate shapes and geometries which cant be done using traditional fabrication processes [1]-[7]. Using this technology, rapid prototyping has received more interest as it has become more accessible and feasible. AM technologies has enabled the manufacturing of parts in plastics, ceramics, and metals which makes it a very versatile process. Despite having a lot of work done on the pros and cons of AM, there still is a need to further clarify. This study will focus on metal additive manufacturing technologies to compare advantages and disadvantages of different metal AM technologies. Comparing the advantages and disadvantages of these processes will enable the designer or operator pick the most suitable manufacturing process for the specific use.
Fossil fuels will continue to play an important role for the forthcoming decades, particularly in certain hard-to-abate transport and industrial sectors. Unconventional oil has emerged as a sizeable contributor to meeting the global energy demand in the energy transition period. However, unfavorable economic conditions compounded by the Covid-19 pandemic have intensified uncertainties regarding their future prospects. This paper explores prospects and challenges faced by unconventional oil resources in the post Covid-19 near- to long-term. Based on recent projections, unconventional oil resources, although significantly affected by the pandemic in the short term, could however reach approximately 30% share of oil production by the early to the mid 2030's.
The influence of topology hybridization on the compressive properties of the mathematically-known triply periodic minimal surface (TPMS) lattice was studied in this paper. The diamond (D) and F-Rhombic Dodecahedral (FRD) lattice structures comprising each of 8 cells were considered. The sandwiched geometries were numerically subjected to a quasi-static compressive force until densification was reached. The energy absorbed and the metamaterial's ultimate strength was estimated. The results revealed that by hybridizing the D lattice with the FRD structure, the specific energy absorbed and ultimate strength of the D lattice were improved.
In this study, we created and validated a model for 'paragraph ending sentences.' To do so, we analyzed a corpus of papers from advanced ESL college-students, identifying 'paragraph ending sentences' that can be categorized as a model composed of 'goal,' 'type,' and 'cue.' 'Goal' refers to the function of the sentence (e.g., summarizing). 'Type' refers to whether the sentence is a claim or a support statement. 'Cue' refers to explicit language indicating the goal. To assess the model, we trained judges to recognize the identified categories. Quantitative and qualitative analysis validated the model, leading us to conclude that the model is a viable teaching intervention with pedagogical credibility. The model is also important as it features in software designed to assist college level ESL student-writers.
This study compared and contrasted some syntactic aspects of the sentence in Arabic and English political speeches, namely sentence length, frequency of sentence types and forms, and passivization. Twenty political speeches in Arabic and twenty political speeches in English were collected from the United Nations General Assembly (UNGA) meetings between 2015 and 2019. The analysis revealed that sentence in the Arabic political speeches is slightly shorter than its counterpart in English. It was also found that the complex sentence is more frequent in the Arabic speeches, while the simple sentence is more frequent in the English speeches. Passive sentences frequency in the Arabic speeches is slightly higher than in the English speeches. The analysis also revealed that these syntactic features were used to perform several functions in the text to serve ideological goals such as blame avoidance, credit-claiming, and political neutrality. Keywords- Political speech, sentence length, ideology, passivization.
Not until the beginning of the 20th century did the recipe begin to be the subject of serious academic interest. It is even more rarely tackled in the realm of translation studies. The purpose of this paper was to examine the recipe as a separate genre. One-hundred recipes were collected from five different sources. One hundred translated recipes were analyzed through parallel-text analysis.The difficulties that translators may encounter in translating recipes from English into Arabic at the lexical, syntactic, textual and cultural levels were identified. Results showed that the English and the Arabic recipe on the macro-textual level were the same; however, there were some differences on the micro-textual level such as the use of indefinite articles for reference, ellipsis, and the use of pronouns. Other results showed that the most commonly used method to handle CSIs was couplets (38%), while the least used method was communicative translation (1%).
This study examines the main SLA challenges that university students encounter and the influence of these challenges on their academic achievement. This research answers two research questions: 'what are the main challenges that university students face in SLA?' and, 'how do these challenges influence the academic achievement of university students?' It uses a quantitative design in the form of a survey, and the participants are university students in the UAE (N= 37). The findings show that SLA challenges affect university students' academic achievement on various levels. This study contributes to linguistics literature generally and in the UAE, and it contributes to theoretical knowledge and proposes pedagogical implications.
Translation can be impacted by metalinguistic factors which push the translator either to render literal meanings or to try their best to communicate the meaning beyond the text. Legal puns are one of the best examples that illustrates the situation of the translator when they face such phenomena. This study scrutinizes legal puns in Khalil Mutran's Arabic translations of Shakespeare's Macbeth and Hamlet; the aim is to investigate if and how the translated puns are rendered with their legal overtones in the target texts. The study examines the puns in the source texts by referring to Shakespeare's Legal Language: A Dictionary (2004) and Shakespeare's Wordplay (2003) and in the Arabic translation by referring to لسان العرب (2008) and معجم اللغة العربية المعاصر (2007). Results show that the translator grasp the combination of punning with legal overtones and translates them into corresponding legal puns, picking Arabic legal terms with double-edged meanings.
This paper examined whether musical experience facilitates L2 pronunciation. The focus was on two common mispronounced English phonemes, /θ/ and /ð/, by L1 Egyptian Arabic speakers. The participants were four musicians and four non-musicians. All participants answered a survey indicating proficiency in English as an L2. The participants also had to undergo a music test (PROMS) to identify the level of their music abilities. For data collection, the students underwent a pre-test, and a post-test that specifically targeted the conflict of the sound /θ/ and /ð/. As for the intervention, participants from both groups attended four hours of phonetic production training. The results of the post-test were analysed to reveal that musicians scored much higher (97.5%) compared to the non-musicians (75%). Although the results of the study are currently in progress, the post-test average scores correlate with previous literature findings that musical aptitude facilitates L2 acquisition among adults
