Neste trabalho investigou-se a atividade fotodinâmica de octaetilporfirina (OEP), octaetilporfirina de vanadil (VOOEP) e meso-tetramesitilporfirina (m-TMP). Este estudo foi realizado através da determinação da constante da velocidade de fotoxidação (k f ) do aminoácido triptofano (Trp). A participação do oxigênio singlete nesta fotoxidação foi determinada através da adição de azida de sódio e água deuterada no meio de reação. Os valores de k f /10 -4 s -1 para a fotoxidação de Trp demonstraram que OEP (2,80 ± 0.05) é mais eficiente do que m-TMP (1,62 ± 0,07) e VOOEP (0,81 ± 0,08). Os valores de k f foram menores na presença de azida de sódio e maiores na presença de água deuterada, sugerindo que o oxigênio singlete é o responsável pela atividade fotodinâmica de OEP, VOOEP e m-TMP. Estes resultados sugerem também que as diferenças na atividade fotodinâmica entre as porfirinas podem ser associadas com as diferenças na estrutura molecular das mesmas. A presença do grupo vanadil (V=O) interfere claramente na atividade fotodinâmica de OEP causando considerável redução na sua eficiência.

The performance of a carbon paste electrode (CPE) modified with SBA-15 nanostructuredsilica organofunctionalised with 2-benzothiazolethiol for determination of Cu(II) ions in sugar cane spirit(cachaça) is described, based on differential pulse anodic stripping voltammetry (DPASV) procedure.The Cu(II) oxidation peak was observed at – 0.03 V (vs. SCE) in phosphate solution (pH 3.0). The resultswere obtained using optimised conditions such as 100 mV pulse amplitude, 3 min accumulation time, 25mV s -1 scan rate in phosphate solution pH 3.0, resulting in a linear dynamic range from 8.0 x 10 -7 to 1.0 x10 -5 mol L -1 Cu(II) and a limit of detection 2.0 x10 -7 mol L -1 . Cu(II) spiked in a cachaça sample wasdetermined with 102.5 % mean recovery at mmol L -1 level. Interference from other metallic cations presentin the sample was avoided by the standard addition procedure.

Published: July 2023

Two series of alkanediyl-a,w-bis (dimethylalkylammonium bromide (n-2-n and n-6-n; n=8, 10,12,and 16) have been synthesized and their micelles properties studied in aqueous solution using pyrene,pyrenecarboxaldehyde (PCA) and 1,8 anilinonaphtalene sulfonic acid sodium salt (ANS) as fluorescentprobes. The micelles from these surfactants have been characterized on the basis of the informationprovided by micelle-solubilized fluorescent probes. The obtained results indicated that the surfactantconcentration at which a marked decrease in l max parameter of pyrenecarboxaldehyde (PCA) occurscorresponds to the CMC determined by conductimetric measurements. Changes in the emission spectraof ANS and PCA observed in the submicellar range for both surfactants series (n-2-n and n-6-n) wereinterpreted as formation of pre-aggregates. It was found that the dimeric surfactants with long spacer (s=6) form more hydrated aggregates when compared with those formed by the n-2-n and C n TAB surfactantsseries. This was attributed to a more difficult packing of n-6-n surfactant molecules to form micelles.

Authors: Lu J. , Jalbout Abraham F. , Zhou Zhongxiang
Published: July 2023

In this paper, we report the stability of the Li(HF) 3- molecular anion calculated at the MP2/6-31++G** and CCSD(T)/6-31++G** level of theory. Five possible conformers of Li(HF) 3- molecular anionshave been determined employing ab initio MP2 method with 6-31++G** basis set. The most stableconformer of five Li(HF) 3- anions is in a cyclic ring structure Li(HF) 3- (1). From our calculations we showthat the molecule is stable towards electron attachment, with an electron adiabatic electron affinity(AEA) of 199.5 meV (233.1 meV with zero point energy correction) and 471.3 meV at the MP2 andCCSD(T) levels, respectively. In addition we present vertical detachment energies of 230.2 meV and 795.8meV at the MP2, CCSD(T), respectively. The importance of the latter has to do with the ability ofexperimental detection of this value.

Published: July 2023

Copolymers of methyl methacrylate (MMA) and triethyleneglycoldimethacrylate (TEGDMA) obtained by photoinitiated polymerization using Fe(III)complexes were submitted to thermogravimetry (TGA) under dynamic air atmosphereand N 2 , and differential scanning calorimetric analysis (DSC). Thermal events wereobserved only between 90 - 110 °C. Glass transitions were observed at ca. 100 °C,followed by an exothermic peak at 170 °C. The exothermic peak was assigned to athermal curing process due to the presence of unreacted vinyl groups of the monomers.DSC revealed to be a useful tool to evaluate the curing completeness in this kind ofmaterial, using small amounts of sample in relatively short time.

Published: July 2023

In this paper, a new, simple and sensitive method for arsenic determination in soil is proposed. This is based on the reduction of silver (I) and iron (III) ions by arsine followed by a complexationreaction of iron (II) with the spectrophotometric reagent Br-PADAP 2-(5-bromo-2-pyridylazo)-5-di-ethylaminophenol. Arsenic determination with a Sandell’s sensitivity of 3.1 10-4 cm-2, linear range from 0.1 μg ml-1 to 2.0 μg ml-1 (r560 = 0.9995), molar absorptivity of 2.45 105 l mol-1 cm-1 and a concentrationdetection limit of 1.4 ng ml-1 (3s) were obtained using a 10 ml sample volume. Selectivity was increased with the use of EDTA as a masking agent. The proposed method was applied for arsenicdetermination in the presence of several ions amounts in digested soil samples. The results revealed that antimony (III), mercury (II), germanium (IV), platinum (IV) interferes at all analyzed proportions.The interferences can be easily removed by the use of EDTA. Precision and accuracy obtained were satisfactory with a R.S.D. < 5 %. Recovery of arsenic in soil samples varied from 95.55 to 102.70 % with a mean of 99.63 %. These results demonstrated that the proposed method is applicable for arsenic analysis in different soil samples.

Supremacy of suprasegmentals in Arabic phonology: Evidence from malapropisms
Authors: Abu Guba Mohammed Nour , Mashaqba Bassil , Huneety Anas , Alshdifat Khalid
Published: July 2023

Speech errors are an important source of information to understand language processing and production. Earlier research focused on different types of errors including semantic and phonological errors while malapropisms, which refer to slips of the tongue involving whole word substitutions that share phonological similarities but are not related semantically, have not received adequate attention in the Arabic language. Drawing on malapropisms in Jordanian Arabic, we bring evidence on the supremacy of suprasegmental phonological aspects in Arabic phonology. This is unexpected as stress in Arabic is non-phonemic and fully predictable, besides Arabic rhythm is much less stress-timed than that of Germanic languages. Data was collected from spontaneous speech over a period of three years. Results showed that malapropisms share the primary stress position, the number of syllables and the word rhythmic pattern with the target words. To a lesser degree, the target and the error share the same rime and initial segments. Findings suggest that suprasegmental features are very crucial in Arabic phonology, like in Indo-European languages. Evidence suggests that formal similarity that is based on the syllabic and metrical structure of words plays a significant role in language processing and the organization of the mental lexicon in Arabic, which suggests that this is a language universal. Furthermore, our findings do not agree with earlier claims that Arabic has a flat syllabic structure. Rather, evidence suggests that Arabic, like English, has a hierarchical syllable structure, which seems to represent another language universal. More research on other Arabic dialects is recommended to corroborate these findings. Disclosure statement No potential conflict of interest was reported by the authors. * Corresponding author: Mohammed Nour Abu Guba, 0000-0002-5007-6439   mabu-gub@sharjah.ac.ae

The paper focuses on the research of the efficiency of three primary forms of teaching and besides, blended learning influence on learning and teaching English as a foreign language at Yuriy Fedkovych Chernivtsi National University, Ukraine, at Faculties of Economics (particularly, Economic Cybernetics), Law, Pedagogy and Psychology, Philology, for two academic years 2020/2021, 2021/2022. The study sample consisted of 120 students from 4 mentioned faculties who took the compulsory academic discipline English for Specific Purposes in the 1st, 2nd and 3rd semesters in compliance with their curriculum. The objectives of the study are to analyze and compare the effectiveness of the practical application of the three primary forms of education (full-time, distant and blended) and to study the impact of blended learning on teaching and learning English as a foreign language in practical classes of the compulsory English course. For the research, a questionnaire survey divided into two parts was used. Each of the survey parts included four items. The second part of the survey was conducted based on the typical 5-level Likert scale. To analyze the elicited data, SPSS (Statistical Package for the Social Sciences) program was used for the qualitative research. The outcomes in both parts are presented in percentages. The study conclusions showed that a blended study is the challenge of the present-day education system and is highly approved by university students. They are sure that using blended learning in teaching EFL at Chernivtsi National University is beneficial, advantageous and productive for improving skills in English as a foreign language course. Four-fifths of the respondents stated that their language proficiency skills significantly enhanced compared to conventional teaching methods.

Second language word processing in sentence contexts: pre-lexical prediction versus post-lexical integration
Authors: Qurbi Essa
Published: July 2023

This study investigated the effects of sentence contexts on the second language (L2) word recognition process. It aims at finding whether second language (L2) learners of English perform similar to English native speakers in terms of using the sentence context to predict upcoming word in their L2. A group of L2 participants and a control group of native speakers (L1) participants performed a cross-modal priming task in which they were asked to make a lexical decision on a visually presented word while listening to a semantically related or non- related English sentence. The test was conducted to determine whether both groups of participants were able to predict an upcoming word based on the context of the preceding sentence that is auditorily presented. The study is conducted using PsychoPy software whereas the data was analyzed using linear-mixed effects modeling in RStudio software. The results showed that the L1 speakers were able to predict an upcoming word based on the context of the preceding sentence. That is, a significantly faster recognition of the related word was observed compared to the less related words. On other hand, the English second language participants were not as able to predict an upcoming word as quickly as the English native speaker participants were. However, the L2 participants showed post-access lexical processing or what is called an integrating process of the presented word to the previous sentence context. That is, an effect of the sentence context was observed with L2 participants, yet only after reading the presented word, they decide whether it is appropriate to the preceding sentence context or not.

On the Impact of Mode of Presentation and Age on Parsing Structurally Ambiguous Relative Clauses
Authors: Sarkhosh Mehdi , Rahmat Mehdi Gaed
Published: July 2023

The relative clause Attachment preferences of female Persian learners of English were investigated regarding their age and modes of presentation (online/offline and holistic/segmented). 50 female native speakers of Persian ranging in age from 15 to 25 participated in the study. The instruments used in the present research included two tests of ambiguous sentences: 1) a grammaticality judgment test, and 2) the main test which was presented in three separate forms: a) Offline, b) online complete presentation (timed) and c) online segment by segment sentence (Self-Paced). This study used the method employed by Kim and Christianson (2013) for determining the attachment preferences of the participants. The results revealed that the participants' age affected the attachment preferences significantly in that adolescents had a clear determiner phrase 1 preference. There was also a statistically significant difference among the three modes of presenting the materials. The findings revealed that learners transferred their attachment strategies from their mother tongue to English, which provided support for transfer hypothesis.  The research findings on whether L2 learners can achieve native like patterns of ambiguity resolution is still less than conclusive and findings seem to suggest that L2 learners apply parsing strategies which are less automatized than native speakers and even at odds with some studies reporting no transfer of L1 parsing strategies. Language teachers should make their learners cognizant of relative clause attachment preferences in English to avert their transfer of their mother tongue strategies in determining the antecedents of the relative clauses.
A Prospectus for Bilingual Early Reading Instruction

Published: July 2023

In this paper, we describe a framework for bilingual decoding instruction, with a call for collaborators. Decoding is the ability to apply knowledge of letter-sound correspondences to pronounce words. We adopt a standard phonological approach for early instruction that could be expanded to include practice with constructive morphemes, like prefixes and suffixes, and reading for meaning. Decades of research have shown that word decoding is a bottleneck in reading comprehension. Unless children develop sight-word reading capabilities, comprehension of texts is severely hampered. The present approach draws on children’s spoken vocabulary knowledge in their native language as a bridge to decoding in a second language. The goal is to develop a tutoring system that draws on current and forthcoming multimedia technologies, and to implement the system in multilingual countries, e.g.: USA, India, Ukraine and across national borders. As a starting point, the authors will use a web platform https://ethicalengineer.ttu.edu designed in 2017 by the USA, Indian, and Ukrainian collaborators, several of them being co-authors of this paper, as a model for the new website for reading instruction. The Ethical Engineer website demonstrates one mechanism through which instructors can reach out to establish connections within and outside their native country around topics and issues of common interest and support educator cooperation and research development. The new model hopes to achieve success comparable to that of the EthicalEngineer. Using computer-based instruction allows for empirical testing of teaching methods, thereby optimizing the educational process. It is important to take advantage of this to ensure the most effective methods are used in early reading instruction for children.

Linguistic strategies for professional politeness among aspiring managers: An analysis of organizational psycholinguistics
Authors: Vlasenko Olena , Maistruk Viktoriia
Published: July 2023

In order to effectively communicate in a professional setting, it is essential for managers to have a mastery of the language specific to their field. One tool that can be used for professional communication is verbal politeness, which involves using appropriate words and phrases to show respect for the listener and soften unfavourable information. These linguistic units promote a culture of professionalism and ethical business relationships and are a key indicator of a manager's speech competence. A psycholinguistic study examined the usage of polite language by aspiring managers. The participants were 218 undergraduate and graduate students enrolled in the Management program across various universities in Ukraine's oblasts. The organizational psycholinguistics research aimed to assess the extent to which aspiring managers incorporate professional language units such as polite words and phrases in their speech. We analyzed the references of 1,308 respondents to determine how politeness language units corresponded to the structural parts of the document. By studying 928 selected language units of politeness, we could assess the level of politeness markers. This indicator reflects future managers' skill level in applying synonymous ranges of politeness. The analysis found that respondents used various linguistic units to soften the impact of unfavourable information when conveying it to others. These units formed synonymous ranges based on context and semantic content. Only half of the students showed a wide range of knowledge and skills in appropriately using polite language. Thus, aspiring managers need to improve their knowledge and practical skills in using a variety of linguistic units of politeness in business documents. Therefore, we recommend implementing programs to improve communication levels for those pursuing higher education in management.

Tradition of Islamic Basic Education in Aceh
Authors: Inayatillah Inayatillah
Published: July 2023

The tradition of basic Islamic education in Aceh adopts the concept of Islamic lifelong education, in which Islamic education is fulfilled from the age of 0. This study aims to identify how the tradition of basic Islamic education in Aceh is through informal, formal, and non-formal education based on the National Education System Number 20 of 2003 and Government Regulation Number 55 of 2007 concerning Religious Education. In addition, this study also aims to observe who plays an active role in shaping the basics of Islamic education in children. This research is qualitative research using a historical approach. Sources of data and information were obtained through a literature review to understand the historical context and changes that have occurred in the tradition of Islamic basic education. The data collected was analyzed descriptively to form a discourse on Islamic basic education in Aceh in the past and present contexts. The results of this study indicate that historically the people of Aceh have only known two educational paths in forming the basics of Islamic education since children aged 0-12 years, namely informal and formal education. Parents are the people who have a significant role in the foundation of the basics of Islamic education in Aceh, in addition to teungku and teachers. For informal education, Aceh has the doda idi tradition which is used to educate children aged 0-3 years. Furthermore, parents accompany their children who are aged 7-8 years to obtain formal basic Islamic education at the meunasah, but this meunasah education changed to non-formal education after the independence of the Republic of Indonesia.
Optik Spektrum Analizörü Kontrolü ve Ölçüm Doğruluğunun Artırılması
Authors: YÜCEL Murat , ASLAN Zühal
Published: July 2023

Optik spektrum analizörü (OSA), fiber optik sistemlerde verilen bir giriş sinyalinin sistem çıkışında büyüklüğünü ve gücünü frekans aralıklarına göre ölçer ve sonuçları grafiksel olarak gösterirler. Ancak OSA’lardan ölçüm alınırken manuel ölçümlerde anlık güç değişiminden dolayı ölçüm doğruluğunda hatalar oluşmaktadır. Bu nedenle ölçüm doğruluğunu sağlamak için çok sayıda ölçüm alınarak ortalama alınması doğruluğu artıracaktır. Bu çalışmada Matlab App Designer ile OSA bilgisayar üzerinden kontrol edilebilmekte ve ölçüm sonuçları istenilen şekilde çıktı olarak alınabilmektedir. Bu platform kullanılarak gerçek OSA ekranı oluşturulmuş ve uzaktan kontrol edilebilir hale getirilmiştir. Kullanıcının art arda aldığı ölçümlerin sonucu bir excel dosyasında kaydedilebilmektedir. Bu sayede kaydedilen tüm ölçümlerin ortalaması alınarak yapılan ölçümde en doğru sonuca ulaşılabilmektedir. Geliştirilen yazılımla fiber optik sistemlerde deneysel çalışmalar yapılırken kullanılan cihazların yazılımlar üzerinden erişilerek daha kolay kullanım sağlanabilmesi ve ölçüm doğruluğunun artırılması amaçlanmaktadır.

Authors: ÖZKAN Kayhan
Published: July 2023

Bu çalışmada ticari broyler hayvanlara enfeksiyöz bronşit aşısının sprey yöntem ile kuluçkahanede ve sahadaki uygulamasının ardından elde edilen aşı alım verileri kıyaslanmıştır. Her iki uygulama sprey metot kullanılarak yapılmıştır. Çalışmada 10.200 ve 10.400 adet giriş kapasitesine sahip 2 adet broyler sürüsünün birine kuluçkahanede, 1 günlük yaşında, diğerine ise 12 günlük yaşta sprey enfeksiyöz bronşit (IB) aşısı uygulanmıştır. Aşılamayı takip eden 4. gün içerisinde her iki uygulamanın yapıldığı sürülerden trake sürüntüleri alınarak RT-PCR analizi yapılmıştır. Kuluçkahanede sprey uygulaması ardından çiftliğe gönderilen civcivlerden 5.gün ve saha sprey aşı uygulaması yapılan sürüden ise 17. gün trakeal sürüntü örnekleri alınmıştır. Sürüntü örneklerinden RT-PCR analizi yapılmıştır. Her iki grubun aşı virüsü varlığı one sample t testi ile kıyaslanmıştır. Elde edilen bulgulara göre kuluçkahanede 1. gün uygulanan sprey uygulaması sonrasında elde edilen aşı alım değerleri, geleneksel saha aşılamasına göre istatistiksel olarak anlamlı bulunmuştur (p<0.05). Saha aşı uygulamaları birçok değişkeni içinde barındırmaktadır ve hayvanların aşı alım değerlerini optimum düzeyde tutmak sınırlı başarıya sahiptir. Bu çalışmada kuluçkahanede üniform yapıda konumlandırılmış hayvanların uygun doz ve teknik ile aşılanmaları neticesinde saha aşı uygulamalarına göre daha yüksek aşı alım oranlarına sahip olduğu saptandı.
