A One-Pot Procedure for The Synthesis of Aromatic Aldehydes in a Heterogeneous Medium
Authors: Bratulescu George
Published: March 2020

Aromatic aldehydes were obtained from halogenated compounds and DMSO in solvent free medium. The method involves a Kornblum`s oxydation of organic halide in mild conditions using microwaves. An inorganic base such as solid potassium bicarbonate is used. The procedure is a smooth alternative to obtain aromatic aldehydes in heterogeneous medium. The important benefits of the method are also the absence of catalysts, the low time, and the good yield of the synthesis.

Elevated cardiac troponin I (cTnI) levels are diagnostic for myocardial injury. Moreover, they are essential for risk stratification in patients with acute cardiac ischemia and heart failure. However, their usefulness is not limited to the previous clinical conditions. The aim of this study was to evaluate the clinical significance of cTnI levels in the emergency department.In 324 patients, out of the 4147 referred to the emergency department, serum levels of cTnI were evaluated and represented the study population. Subjects were divided into 2 groups: Group 1 (66 patients) with cTnI ≥ 0.04 ng/mL and Group 2 (258 patients) with cTnI level [ 0.04 ng/mL. The clinical characteristics, laboratory data, ECG findings, echocardiographic abnormalities and discharge diagnosis were compared between the two groups. Patients with cTnI ≥0.04 ng/mL had more often a history of ischemic heart disease, lower levels of oxygen saturation, higher levels of blood glucose, increased white blood cells count, higher heart rate and deeper ST-segment depressions on ECG. The most common discharge diagnosis was heart failure. Although an elevated level of cTnI is highly suggestive for myocardial injury, it should always be interpretated in the clinical context. Heart failure is an important diagnosis in patients with elevated cTnI levels.

Published: March 2020

Chromatographic profile of volatiles organic compounds (VOCs) from several varieties of multifloral and unifloral honey produced in Transylvania, Romania, was analysed in order to determine the differences between them. VOCs collected using solid phase microextraction (SPME) technique were analysed by gas-chromatography coupled with mass-spectrometry (GC-MS). The fiber used was Carboxen / PDMS (polydimethylsiloxane) 75�m. By qualitative analysis, a number of 98 volatiles in unifloral honey and 52 volatiles in multifloral honey were identified. The differences regarding volatile compounds of multifloral honey were observed to be between varieties from different areas of Transylvania (mountain, plain, hill and urban area) while in the case of unifloral assortments (rapeseed, acacia, sunflower and linden) differences were observed at specific compounds. Compounds identified in our samples were grouped into main classes of substances: hydrocarbons, alcohols, aldehydes, ketones, organic acids and their esters, furan and pyran derivatives and terpenes.
The Influence of Natural Saline Solutions on Dihydrate Copper Chloride Crystallization
Authors: Cimpean Cristina-Daniela , Berteanu Mihai
Published: March 2020

The crystallization of salt solutions is strongly affected regarding the shape of the crystalline network by the presence of impurities, even in extremelly small quantities. This sensitivity is extremely high especially for dihydrate copper chloride (DCC) solution. The phenomenon is used for early diagnostic in medicine and for food quality assessment and named sensitive crystallization or biocrystallization. The evaluation is based on the morphology of the DCC network that crystallizes on a Petri plate containing a fine film of this solution to which a small amount of the substrate analyzed is added. For this reason, the understanding of the influence of all physico-chemical factors on the crystallization of the DCC solution is very important. To help elucidate some of these aspects, we analyzed by biocrystallization a series of 30 mineral waters from Romania, following their influence on the morphology of the DCC crystallization network. This is the first paper about biocrystallization of natural mineral waters. Following this analysis we noticed specific patterns generated by the predominant chemical composition and the total mineralization of the analyzed waters. These results can be extrapolated in the medical and agro-food field, contributing to the correct interpretation of the biocrystallisation test.

3-(thiazol-2-yl carbamoyl) propanoic acid was synthesized by the reaction of 2-aminothiazole and succinic anhydride, which was employed as ligand (LH) for further reaction with Co(II), Ni(II), Cu(II), Zn(II) and Bi(III) chlorides at ambient conditions to afford respective metal complexes, denoted as Co-L2, Ni-L2, Cu-L2, Zn-L2 and Bi-L3. Both the ligand LH and metal complexes were characterized by techniques FT-IR, 1H-NMR, 13C-NMR, powder XRD, TGA and conductometry. FT-IR and NMR studies revealed that ligand (LH) behaved in anisobidentate fashion via carboxylate moiety. The ligand and metal complexes are also screened for their antibacterial and antifungal potential and found non-significant activities by most of the complexes, luminescent studies were also made and found Bi-L3 appreciably luminescent.

Published: March 2020

The conversion of light hydrocarbons resulted as by-product of petroleum refining (mixtures of (n + i) butanes, 52.28 � 63.20 vol.%, (1-, cis-, trans-, 2-) butenes, 28.64 � 36.43 vol.% and propane � propylene, 4.79 � 14.64 vol.%) over bifunctional 5% ZnO/HZSM-5 co-catalyst in a fixed-bed stainless-steel reactor (Twin Reactor System Naky) at 450�C, 4 atm. total pressure and at a space velocity (WHSV) of 1 h-1 have been investigated. The results indicate that the selectivity to light aromatics � benzene, toluene and xylenes (BTX) � and to both the gaseous C1, C2 - C4 hydrocarbons and liquid (i + n) C5 � C10 aliphatic hydrocarbons depends on the time on stream of the process. This is a result of coke deposition (polyunsaturated compounds) and catalyst deactivation. The aromatics BTX represent 59-60 wt% in the liquid product during the first 24-36 hours time-on-stream and only 20-30 wt% after 40 hours of reaction when the aliphatic hydrocarbon C5 � C10 (mostly iso) and ]C10 (denoted �oligo�) reach to 70 � 80 wt%. The aromatic products were principally toluene, xylenes and benzene, theirs concentration varying with the time on stream of the process. The initial aromatization process described as dehydrocyclodimerization of alkanes and alkenes, principally to aromatics BTX and molecular hydrogen is accompanied by an oligomerization, isomerisation, cracking and alkylation process to form finally in the liquid product an excessively mixture of iso- and normal- C5 � C10 aliphatic hydrocarbons and ] C10.
Academic Dishonesty in Extensive Reading Programs: Stories and Strategies from Student Interviews
Authors: Tagane Yuichi , Naganuma Naeko , Dougherty Patrick
Published: March 2020

Extensive reading (ER) has become an accepted methodology in increasing student reading fluency. However, there are issues that teachers face when implementing an ER program. This study, completed at a small English-medium university in Japan, addressed a key problem in ER program implementation: student academic dishonesty. The research, based on student interviews and supplemented by teacher experience, identified five categories of academic dishonesty: (a) asking for a friend’s help; (b) referring to online resources in lieu of reading or completing a reading report; (c) reading and writing about topics that were already familiar to the student; (d) watching movies instead of reading; and (e) others. The findings indicated an equal number of methodologies that are useful in countering academic dishonesty. It was suggested in the findings that, in addition to discouraging academic dishonesty in ER programs, the methodologies can also work to enhance the ER experience for students.

Authors: Tada Wendy
Published: March 2020

The aim of this study was to better understand pre-service teachers’ familiarity with and interest in phonics and how these factors might influence the development of future phonics courses. For this study, 86 first year undergraduate students attending a national university for teacher education completed a survey in 2017. Participants from one class submitted a journal after attending three lessons introducing phonics. The survey results showed that most participants did not learn phonics before entering university, and admitted they had trouble reading new English words. Furthermore, according to the journal comments, participants gained an awareness of their own pronunciation skills, and an understanding of the key points of phonics and how it can be taught using songs.

本研究では、フォニックスに関する教育実習生の学習経験と関心、及びこれらの要素が将来のフォニックスコース開発にどのような影響を与えるかをより把握することを目的とした。本研究に関して、2017年にある国立教育大学で86名の1年生の学部生が調査を行いました。また、あるクラスからの参加者が、フォニックスを紹介するレッスンに3回参加した後、日誌を提出しました。その調査結果によると、ほとんどの参加者は大学入学前にフォニックスを習得しておらず、ほとんどの参加者は英語の新しい単語を読むのに問題があると認めました。さらに、その日誌のコメントによると、自分の発音スキル、フォニックスの要点、及び歌をどのように使って教えているかという認識が得られたと結論づけることができました。

Authors: Babour Islam A. , Mohamed Maha B. , Shehabi Asem A
Published: March 2020

Background: Pseudomonas aeruginosa is a pathogenic organism responsible for frequent wound and nosocomial infections worldwide. Its infections are difficult to control since the organism is known to rapidly develop antibiotic resistance and becomes multidrug-resistant (MDR) during treatment of patients.

Aim of the study: This study was intended to investigate the occurrence of certain important types of (ESBL) and (MBL) enzymes in association with important specific virulence factors  associated with P. aeruginosa clinical isolates from Khartoum, Sudan.

Methods: This study investigated 70 P. aeruginosa isolates which were collected from patients admitted to four major hospitals in Khartoum  (Fedail, Ribat, Ibn Sina and Soba hospitals). These isolates were recovered from 40 wound swabs (57.1%), 27 urine samples (38.6%), and 3 pleural fluid samples (4.3%) of patients. Higher numbers of isolates were recovered from males 42 (60%) than in females 28 (40%). All P. aeruginosa isolates were first confirmed by conventional biochemical and second using molecular PCR tests.   PCR methods were also used for detecting the presence of the virulence genes ToxA, AlgD, LasB, exoS, exoU, CTX, GES-1, and genes of VIM, IMP, KPC, CTX, VEB-1 and SHV-1.

Results:   Antimicrobial susceptibility testing of P. aeruginosa isolates showed a high resistance to azetronam 49 (70%), followed by ceftazidime 32 (45.7%), 16 ciprofloxacin (22.9%), gentamicin 13 (18.6 %), piperacillin-tazobactam 11 (15.7%), amikacin 9 (12.9 %), and imipenem 6 (8.6%) showed the least resistance. All isolates were positive for algD and lasB (100%), followed by toxA (90%), exoS (34.3), exoU (24.3%), respectively. The rates of detected ESBL genes blaTEM, blaCTX-m, blaSHV-1,GES-1, were 3.3%, 6.6%, 10%, 3.3%,10%, respectively, but all isolates were negative for bla-KPC and bla- VIM and IMP . The percentages of pigment production were 61.4% for pyocyanin, 37.1% for pyoverdin and 1.4% for pyorubin.

Conclusion: The study demonstrated high rates of antimicrobial resistance markers to most commonly used antibiotics in treatment of P. aeruginosa infections. The majority of the isolates from urine and wound samples carried at least three potential virulence factor genes of algD, lasB and toxA and without any significant relation to their antimicrobial resistance markers.

Authors: Van Pham Binh , Huu Phan Huynh , Le Ngo Lam , Nguyen Hang Thi Thuy , Le Ky Van , Chu Dinh Thien , Bac Nguyen Duy
Published: March 2020

BACKGROUND: Hepatocellularcarcinoma (HCC) metastasis include intrahepatic and extrahepatic metastasis. Similar to intrahepatic metastasis, extrahepatic metastases are not unusual in cases with HCC. However, colonic metastasis is infrequent.
CASE REPORT: We describe a clinical case, he was diagnosed with HCC a year ago, treated with TACE (transarterialchemoembolisation), re-examined with abdominal pain and defecation disorder. The tests such as CT scan, colorectal endoscopy, fine needle aspiration (FNA) revealed secondary metastatic lesion of HCC in sigmoid colon. This is the first gastrointestinal (GI) tract metastatic we have encountered.
CONCLUSION: HCC metastases of the colon are rare, especially cases of hematogenous spread. The prognosis of these patients is often very critical. Indications for surgical removal of the lesion may be used if the general situation of patient is acceptable.

Authors: Tu Nguyen Phuong , Nha Pham Ba , Hung Nguyen Duy , Minh Nguyen Hoang , Anh Hoang Ngoc , Chu Dinh Thien
Published: March 2020

BACKGROUND: N-methyl-d-aspartate receptor (NMDAR) antibody encephalitis appears common in the world, but the number of clinical cases in Vietnam which were recorded is rare.
CASE REPORT: We describe two new cases of disease in recent years with the aim of contributing to diagnosis and treatment experiences. These cases were noted over the past 3 years with the patients who have been treated at lower levels but have no results. They came to us when symptoms became worse and therefore required prolonged treatment with special intensive care facilities. The atypical and easily confused symptoms are the reasons that make the disease be detected late; leading to a much higher cost of treatment and the complication may appear in the patient. In the past, patients with these manifestations were diagnosed with unexplained encephalitis and severe sequelae or death. Autoimmune encephalitis has many types; NMDA encephalitis associated with ovarian teratoma is the most common autoimmune encephalitis in young women.
CONCLUSION: In conclusion, based on the case report, we hope to contribute some experiences on the diagnosis and the strategy in early treatment. With most female patients at very young age, early treatment to avoid complications will help patients have a quality life and maintain reproductive function.

BACKGROUND: β-thalassemia is one of the most common monogenic diseases worldwide. Preimplantation genetic testing (PGT) of β-thalassemia is performed to avoid affected pregnancies has become increasingly popular worldwide. In which, the indirect analysis using short tandem repeat (STRs) linking with HBB gene to detect different β-globin (HBB) gene mutation is a simple, accurate, economical and also provides additional control of contamination and allele-drop-out ADO.
AIM: This study established microsatellite markers for PGT of Vietnamese β-thalassemia patient.
METHODS: Fifteen (15) STRs gathered from 5 populations were identified by in silico tools within 1 Mb flanking the HBB gene. The multiplex PCR reaction was optimized and performed on 106 DNA samples from at-risk families.
RESULTS: After estimating, PIC values were ≥ 0.7 for all markers, with expected heterozygosity and observed heterozygosity values ranged from 0.81 to 0.92 and 0.53 to 0.86, respectively. One hundred percent of individuals had at least seven heterozygous markers and were found to be heterozygous for at least two markers on either side of the HBB gene. The STRs panel was successfully performed on one at-risk family.
CONCLUSION: In general, a pentadecaplex marker (all < 1 Mb from the HBB gene) assay was constituted for β-thalassemia PGT on Vietnamese population.
Modelling Power in Anarchist Perspective
Authors: Pritchard Gareth
Published: March 2020

An adapted version of the taxonomy of power developed by Starhawk and Uri Gordon can help us to construct an integrated model of power that is consistent with anarchist principles. Rather than conceptualising power as a pyramid, in which power emanates from the apex and cascades down
the ranks, we should see it as a dynamic matrix within which power is continually shifting both in quantitative and qualitative terms. The overall power (power-to) of individuals and groups is derived from a combination of coercive power (power-against), social power (power-with) and power-from-within.
We will only be able to survive as a species if we can find ways to limit the exercise of all forms of coercive power, to unleash the multiplier effect of social power, and to distribute power-to as widely as possible. To achieve these goals, it is necessary to reconceptualise the nature of
power itself.
Demystification of Artificial Intelligence in Education – How much AI is really in the Educational Technology?
Authors: Renz André , Krishnaraja Swathi , Gronau Elisa
Published: March 2020

The data-driven development of education through Learning Analytics in combination with Artificial Intelligence is an emerging field in the education sector. In the field of Artificial Intelligence in Education, numerous studies and research have been carried out over the past 60 years, and since then drastic changes have taken place. In the first part of this paper we present a brief overview of the current status of Learning Analytics and Artificial Intelligence in education. In order to develop a better understanding of the relationship between Learning Analytics and Artificial Intelligence in education, we outline the relationship between the two phenomena. The results show that the previous studies only vaguely distinguish between them: the terms are often used synonymously. In the second part of the paper we focus on the question why the European market currently has hardly any real applications for Artificial Intelligence in education. The research is based on a meta-investigation of data-driven business models, in particular the so-called Educational Technology providers. The core of the analysis is the question of how data-driven these companies really are, how much Learning Analytics and Artificial Intelligence is applied and whether there is a causal connection between the growth of the Educational Technology market and the application relevance of Artificial Intelligence in Education. In the scientific and public discourse, we can observe a distortion between the theoretical-conjunctive understanding of the application of Artificial Intelligence in Education and the current practical relevance.

Conclusions include measures and strategies that coincide with UNWTO 2018 recommendations.
Managing Change and Development Through Strategic Leadership and Governance in South African Social Movements
Authors: Tshishonga Ndwakhulu Stephen
Published: March 2020

Proactive and reactionary social movements emerged throughout the world in response to inter-sectoral issues such as health, education, economy, environment. For managing and sustenance of social movements, forging collective identity, social mobilisation and campaigning, accountability and usage of demonstrations are fundamental. An effective use of these mechanisms are dependent on having strategic leadership and governance institutionalised to manage and sustain organisational change and development. This chapter therefore explores the strategic leadership and governance imperative for managing and sustaining organisational change and development within the context of South African social movements. Social movements such as Abahlali-baseMjondolo (informal settlement) and Treatment Act Campaign (health) were used as case studies to explore the dynamics that underpin social movements in their quest to manage transformational change and development.

Published: March 2020

Traditionally, the gold has been approved as a safe-haven investment after the collapse of Breton Woods. The global investors especially prefer to rebalance their portfolios by purchasing gold or its derivatives during financial crises. This research explores realized dynamic linkages between gold and the advanced stock market indices, after the end of the 2008 economic recession. This chapter used the fractionally co-integrated ECM by utilizing intraday data from 2013 and thereafter. The empirical outcomes support that there is a negative-realized dynamics between the advanced stock markets and the gold's price in the short and in the long run. Specifically, the short-term dynamics of gold's price seems to be higher on the French and Japanese stock market indices. Lastly, the long-term dynamics of gold's price seems to be higher on the Dow Jones and the FTSE100.

Published: March 2020

The Islamic finance industry is estimated around $1.7 trillion with substantial growth momentum in the past decades. It is now too important to be ignored, particularly in the Middle and Far East. This chapter reviews the most salient features of Islamic finance that distinguish it from the rest of the conventional financial universe. A significant volume of research focuses on the comparative performance of Islamic and conventional banks across a wide range of metrics, such as profitability, risk, and efficiency. Islamic stock and bonds markets are also an important segment of the related comparative literature and we reviews these studies, too. This chapter provides a comprehensive and up-to-date review of the extant literature, useful for academics and practitioners with little or significant experience in the Islamic finance sector.

Institutional repositories (IRs) are emerging trends in scholarly discourse among members of the academic community in Nigeria. Global practice shows that many IRs are administered by librarians in the academia. This article examines the nexus between libraries and IRs. It observed that though the emergence of IRs holds great advantage for academic institutions, many Nigerian institutions, especially universities, do not have functional IRs because of the inability of their libraries to run them. The article further identifies the digital divide, inadequate financing, the lack of ICT skills and awareness as well as copyright issues as challenges inhibiting the establishment and management of IRs in Nigeria. Recommendations are made for dealing with the identified challenges.

Published: March 2020

The role of gender in the design of technologies has been a topic of growing importance in fields such as interaction design, HCI, and games. Understanding that technology development and usage practices emerge within the cultural processes, the authors propose in this chapter a discussion about the notions of traditional femininity, its relation to video games, as well as new approaches to female representation. It is also assessed the cultural understanding of gender, sex, and sexuality, as well as how these notions may influence the players experience. The issues discussed and briefly analyzed here point to a production and regulation of gender by technologies such as video games. Therefore, the goal is to assess how gender notions and relations influence the design and use of games in terms of visuals, narrative and sociability.

Role of Overlap Ratio on the Microstructure of Friction Stir Multiseam Cladded Copper-Stainless Steel Lap Joints
Authors: Lakshminarayanan A.K. , Harikrishna K. L.
Published: March 2020

Dissimilar welding of copper to stainless steel using conventional welding processes usually exhibits defects such as solidification cracks, lack of fusion and deterioration in mechanical properties due to the difference in the base metal properties. This is mainly due to minimum solubility of copper in stainless steel. Use of solid state welding such as friction stir welding can be potential solution to this problem. This study is carried out with the aim of cladding copper sheet on a stainless steel by friction stir welding variant known as friction stir cladding. Considering practical applications, to clad copper over stainless steel sheet, multi seam friction stir cladding procedure must be adopted. Though many parameters need to be considered, overlap ratio is one of significant factor which affects the microstructure of clad joints. Hence, five overlap ratios namely 0%, 25 %, 50 %, 75% and 100 % were used to fabricate the dissimilar friction stir copper-stainless steel clad joints. Microstructural analysis was carried out at different regions of clad joints using optical microcopy and correlated with bond strength values

Published: March 2020

Ambroxol (2-amino-3,5-dibromo-N-[trans-4-hydroxycyclohexyl]benzylamine), an over-thecounter product, is a mucoactive agent and has been used widely to treat both acute and chronic respiratory diseases since 1978. This review aims to provide an overview of the clinical evidence available on the use of ambroxol in children with acute and chronic respiratory diseases. Data for this review were obtained from both published and unpublished clinical studies, and real-world evidence studies. Although conducted prior to the introduction of Good Clinical Practice (GCP), these studies, representing almost 1,300 pediatric patients, report strong clinical outcomes following the use of ambroxol in pediatric patients. Furthermore, efficacy findings were consistent irrespective of age, including for patients as young as 1 month old. Additionally, the majority of studies found ambroxol to be well tolerated in children. Taken together, the clinical evidence for ambroxol shows treatmenteffects that offer significant benefits to pediatric patients for its licensed use as a secretolytic therapy in acute and chronic bronchopulmonary disorders associated with abnormal mucus secretion and impaired mucus transport. The findings from this review indicate that ambroxol, for its intended over-the-counter indications, is both efficacious and well tolerated in children and that the favorable benefit/risk profile of ambroxol reported in adults extends to the pediatric population, starting from early infancy, with acute and chronic respiratory diseases.
IDENTIFICATION AND FUNCTIONAL CHARACTERIZATION OF GERMLINE GENETIC VARIANTS PREDISPOSING TO DIFFERENTIATED THYROID CANCER RISK
Authors: Figlioli, et al. (#) Gisella
Published: March 2020

Differentiated thyroid cancer (DTC) is the most common endocrine tumor, showing a high incidence in Italy. A significant higher risk of this cancer is described in first-degree relatives of DTC patients compared to the general population suggesting that germline genetic variants may contribute to its development. Previous genome-wide association studies (GWASs) on DTC have identified robust associations with single nucleotide polymorphisms (SNPs) at chromosomes 2q35, 9q22.33 and 14q13.3. In order to identify additional DTC susceptibility loci, a novel GWAS on the Italian population was conducted. The GWAS was followed by validation studies, where the most interesting SNPs were replicated in a larger Italian population and other European cohorts. Previously observed association for 2q35 and 9q22.33 was confirmed. Moreover, a strong relationship of DTC risk was found with SNPs on 14q24.3 and 20q11.22-q12 across all populations and SNPs on 3q25.32, 5q14, 7q21, 9q34.3, 11p15, 13q12.12 and 20p11 only among Italians. According to ENCODE Project data, many of these SNPs are located in transcription regulatory regions and eQTL analyses showed that five of the associated SNPs may affect the expression levels of their closest genes in different human tissues, including thyroid. In conclusion, novel DTC risk alleles were identified and new insights into their possible functional role were discovered.

They show his constant research of the truth both in human rational knowledge and in faith, which must never be in disagreement. He always tries to overcome, with sometimes straightforward and sometimes sophistic arguments, any inconsistency of the scientific knowledge with the literal or allegoric interpretation of the Holy Scriptures.
Escalation
Authors: Bekhet Abir K. , Kailunas Courtney A. , Atayan Alina T.
Published: March 2020

Background:

Abusive relationships are highly prevalent in our society, but often go unnoticed. Research showed that dating violence continues to escalate in college student populations.

Purpose:

The purpose of this study is to determine the effectiveness of the video as a chosen method of education in raising the college students' awareness regarding warning signs of an abusive relationship.

Design:

This study used a descriptive qualitative design.

Sample/Data Collection:

Five focus groups of college students' participants (freshmen to seniors) were recruited to participate in the “Escalation” workshop. To facilitate discussion, each focus group originally had 15 college students for a total of 75 college students' participants. Five participants dropped of the study the last minute due to conflicting schedules and personal situations. Each focus group lasted for 90 min and consisted of watching a 38 min “Escalation” video that depicts scenarios of abusive relationships and a pre- and a post-qualitative discussion.

Results:

The results of the study and the identified themes illustrate the broadened perspectives participants gained through participating in the workshop. Insights from participants became less focused on physical abuse and began to include more mental and emotional effects of abuse in their responses. This study showed that most participants were not previously aware of the progression and scope of violent relationships.

Discussion/Conclusion:

By recognizing the early signs of an abusive relationship, it is more likely for victims and/or peers to intervene in a safe manner rather than continuing to allow an abusive relationship to escalate to its full potential of violence and physical harm.
Spectral properties and the dynamics of quasi-2-expansive operators
Authors: Shen Junli , Ji Guoxing
Published: March 2020

An operator T on a complex Hilbert space is called a quasi-2-expansive operator if T^{*3}T^{3}-2T^{*2}T^{2}+T^{*}T\leq0, which is a further generalization of 2-isometric operator. In this paper, some basic structural properties of quasi-2-expansive operators are established with the help of operator matrix representation. Using these results, we show that the spectrum is continuous on the class of all quasi-2-expansive operators. Moreover, we verify that Weyl's theorem holds for quasi-2-expansive operators. Finally, we prove that a weakly supercyclic quasi-2-expansive operator is a unitary operator.

Abstract. Aerosol iodine isotopes are pivotal links in atmospheric
circulation of iodine in both atmospheric and nuclear sciences, while their
sources, temporal change and transport mechanism are still not well
understood. This work presents the day-resolution temporal variation in
iodine-129 (129I) and iodine-127 (127I) concentrations in aerosols
from Xi'an, north-west China, during 2017/18. Both iodine isotopes have
significant fluctuations with time, showing the highest levels in winter,
approximately 2–3 times higher than in other seasons, but the
correlation between 129I and 127I concentrations reflects that they
have different sources. Aerosol 127I concentrations are found to be
noticeably positively correlated with air quality index and five air
pollutants. Enhanced fossil fuel combustion and inverse weather conditions
can explain the increased concentrations and peaks of 127I in winter.
The change in 129I concentrations confirms that the source and level of
129I in the monsoonal region were alternatively dominated by the
129I-enriched East Asian winter monsoon and the 129I-poor East
Asian summer monsoon. The mean 129I∕127I number ratio of
(92.7±124)×10-10 provides an atmospheric background
level for the purpose of nuclear environmental safety monitoring. This study suggests that locally discharged stable127I and
externally input 129I are likely involved in fine particles formation
in urban air, which provides insights into the long-range transport of air pollutants
and iodine's role in particulate formation in urban atmosphere.
