Willingness to Communicate and Second Language Speech Fluency: An Idiodynamic Investigation of Attractor States
Authors: Nematizadeh Shahin
Published: July 2021

Willingness to communicate (WTC) has recently been researched as a dynamic variable, with some investigations viewing it as a complex dynamic system (CDS). One important property associated with CDS is the notion of attractor states, which are characterized by stable patterns of behavior. The present study employed an idiodynamic method to monitor per-second WTC changes with 20 participants during three-minute speaking tasks. Using idiodynamic graphs illustrating the WTC dynamics, patterns of stability were identified as the unit of analysis for WTC attractors. Temporal measures of the utterances that coincided with the WTC attractors were also examined. Results demonstrated that attractors were likely to emerge in both WTC and L2 fluency, and largely depended on two categories of content-related and linguistic-cognitive factors. Data analysis also indicates that WTC and L2 fluency exhibited parallel dynamics in most of the cases. The study’s findings yield pedagogical implications that are discussed at the end.

Otitis media in children causes hearing loss, serious complications, negatively affects the child's development. Maxillo-facial pathology changes anatomical relationships in the region of the middle ear. The aim of the paper was to analyze the peculiarities of the middle ear in children with maxillofacial pathology and to optimize the management of otitis media in children in this group. A prospective study was performed based on middle ear monitoring in children with maxillofacial pathology, complex detailed examination, treatment according to developed algorithms and post-surgical middle ear monitoring. The evolution of otitis media in children with maxillofacial pathology has obvious features: the tendency to chronic purulent inflammatory process in middle ear and progression of hearing loss. Children with maxillo-facial pathology require monitoring of the middle ear for early diagnosis of otitis media and appropriate treatment.

Steatonecrosis of the mammary gland is necrosis of its adipose tissue, followed by replacement with scar tissue. Lipogranuloma is known as a benign inflammatory process, necrosis of breast fat occurs due to iatrogenic breast trauma. Most often, fatty necrosis is seen in women with large breasts – in women with small breasts, it develops much less often. It is important to diagnose lipogranulomas because it can often mimic breast cancer. Fat necrosis of the breast is a common pathological condition, with a wide variety of presentations on mammography, ultrasound and MRI. The incidence of fatty necrosis of the breast is estimated at 0.6%, representing 2.75% of all breast lesions.

Organ-сonserving operations in breast cancer include performing extended sectoral resections with regional lymphadenectomy. In the case of these interventions, immediate histological examination of the safe margins and subareolar area will be mandatory. Overly economical tactics are associated with the risk of breast cancer recurrence. Organ-preserving breast cancer surgeries, supplemented with radiation therapy, are a safe alternative to mastectomy with the correct selection of patients with early forms.

About one in two women has symptoms of breast formation. According to various data, the frequency of detection of benign pathologies of the mammary gland is much higher compared to the frequency of referring women to the doctor with these pathologies. Benign tumors of the mammary gland are characterized by a slow, expansive growth (compresses the neighboring tissue), are well encapsulated, most are the result of hormonal changes (hyperestrogenemia, hyperprolactinemia), after excision rarely recur, do not invade local tissues and do not metastasize to others. organs. The basic treatment is surgery – excision of the breast formations. Recurrences rarely occur, do not invade adjacent tissues and do not metastasize to other organs.

Planning, property and profit: the use of financial viability modelling in urban property development
Authors: Mitchell Edward
Published: July 2021

By drawing upon McAuslan’s analysis of the ideologies underpinning land use planning law, this paper examines financial viability modelling and legal processes in the context of local authority decision-making related to property development on large urban sites. A local authority can make a site ready for development by using ‘compulsory purchase’ powers to acquire land, by transferring that land to a property developer and by granting that developer planning permission to commence construction. Analysis of case law, academic criticism of viability modelling practices and a recent property development project highlight issues arising when local authority planning departments use viability appraisals to legitimise decisions purportedly taken in the public interest. An in-depth examination of viability modelling within local authority estates departments then opens a new site for critical inquiry of local authority land acquisition practices. The paper’s conclusions reflect upon how financial viability modelling shapes decision-making, despite questions surrounding both modelling techniques and the outputs that viability appraisals produce.

Published: July 2021

" In this study, gas flow field were simulated using ANSYS 2020R2, Fluid Flow Fluent computational fluids dynamic (CFD) software based on the continuity, velocity, temperature, energy and k -  turbulence. The overall objective of the study is to compare the pressure and velocity maps inside the wet scrubber system for two different scrubber designs. I have choose to analyse an In-Line scrubber bottom inlet, type I, and In-Line scrubber side inlet, type L. Bottom entry or side entry designs to allow a direct up-flow configuration and simplify engine exhaust gas duct routing for any type of vessel. The flow in a wet scrubber is very complex due to the interaction between dust particles, water droplets, and bulk water and flue gas. The flue gas flow is turbulent and there are multiple phases (gas, liquid and solid).
CFD codes that predict gas flow patterns are based on conservation equations for mass, momentum and energy.
The results show that the residuals have a very good job of converging at minimum flow contours and vectors at the inlet across the scrubbing chamber and outlet shows a distributed flow. The velocity profiles have fully conformed to the recommended profile for turbulent flow in pipes.
As can be seen in the figures above, the velocity flow contour inside the scrubber is higher in the scrubber side inlet.
Even though I choose to study the simplified scrubber model without taking into account that spray nozzle improve mixing between the scrubbing liquid and waste gas; from the results obtained, it can be deduced that the numerical simulation using CFD is an effective method to study the flow characteristics of a counter-flow wet scrubber system.

TOOLS TO ENGAGE YOUTH IN ENVIRONMENTAL ISSUES DURING COVID-19 PANDEMIC: CONSTANTA MARITIME UNIVERSITY APPROACH
Authors: Sundri Mirela-Iuliana , Memet Feiza
Published: July 2021

Environmental sustainability must be considered as the main target of humanity. To achieve this goal, the activities of many people must change into pro-environmental behaviour. This is often difficult because it involves high costs, giving up some daily habits and getting out of an artificial comfort. In this sense, education has an essential role to play. Young people are the target group for which appropriate methods must be found to help raise awareness of environmental issues and their involvement in solving them. In the current situation, under the restrictions caused by the Covid-19 pandemic, practical applications with large groups of students and observation of the wild environment is difficult to achieve. In November 2020, the Department of Mechanical and Environmental Sciences within the Maritime University of Constanta organized online the activity “S.O.S. Nature” where different environmental processes have been highlighted through simulation programs. The event aimed to increase the awareness of young people about environmental pollution and its consequences, as well as stimulating transversal skills by high school students participating. The interest given by the large participation in this event and the knowledge gained in this activity underlined the importance of modelling and simulation as useful tools through whose comprehensive approach young people can understand complex environmental issues.

Published: July 2021

In the modern times, energy efficiency is of high interest because there is direct link between this concept and energy conservation, economics, environment and sustainable development. The energy efficiency intensification at international level is closely follow by national leaders and worldwide governments and organisations and by top companies as well. Considering this obvious aspects, higher education institutions are deeply involved in involving energy efficiency in the curricula of future professionals, in order to allow them to gain skills that will help in solving challenges specific to this activity. In this international context, Constanta Maritime University introduced in the curricula of the students enrolled in the specialization called Engineering and Environment Protection in Industry a discipline dealing with this very important activity, named Thermal Efficiency of Buildings and Industrial Processes. This paper is investigating the manner in which our students have mastered the tools of energy efficiency assessment of refrigeration systems, throughout a questionnaire applied to them, at the end of the chapter dedicated to these technologies. The students had to write short comments to very specific questions. Analysis of the comments helps the lecturer and the students to take appropriate measures in the next future. Thus, the feedback resulted to be quite positive because most of the students gained the knowledge provided in this respect. Still, delicate concepts, such as entropy, exergy or exergy destruction seem to raise difficulties to some students. In this respect, results that such an intermediary assessment has to be repeated more often, for other kind of technologies discussed during this course, with the involvement of the concepts introduced by the second law- which are essential in energy efficiency assessments.

Objectifs: Le but de cette étude était de déterminer la prévalence du portage de Staphylococcus aureus résistant à la méticilline (SARM), d´identifier les types de résistances et d'en analyser les facteurs. Matériel et méthodes: Une étude transversale a été menée auprès des patients et des volontaires. Après leur consentement éclairé, des écouvillonnages nasaux réalisés chez des patients ont permis d'isoler et d'identifier les souches de Staphylococcus aureus par la méthode biochimique. La résistance à la méticilline et les résistances associées ont été déterminés par la méthode de diffusion des disques selon la norme du comité de l´antibiogramme de la société française de microbiologie. Résultats: Sur un total de 189 échantillons analysés ont permis d'isoler 10 SARM soit une prévalence globale de 5,29% (7,95% chez les patients et 2,97% parmi les volontaires) (p=0,24). La fréquence de SARM parmi les S. aureus a été de 27,77% dont 31,81% chez les patients et 21,42 % chez les volontaires. Les SARM ont été résistants à 100% et 66,67% à la norfloxacine et à 57,14% et 33,33% à l´érythromycine respectivement chez les patients et chez les volontaires. Cependant la gentamicine a enregistré une sensibilité de 100%. Le sexe, l'âge, la prise antérieure d'antibiotiques n'étaient pas associés au portage de SARM. Conclusion : Cette étude sur la prévalence de Staphylococcus aureus résistant à la méticilline rapporte des résultats inquiétants. Il y a une urgence à développer les mesures de surveillance de la diffusion de ces souches multirésistantes.

Published: July 2021

This work demonstrates the effect of Ag/Au and Au/Ag/Au nanolayers on the performance of chitosan (CS)-graphene oxide (GO) surface plasmon resonance (SPR) sensors for Pb(II) ion detection. The CS-GO SPR sensors are  fabricated on a bi-metallic 40 nm Ag/10 nm Au and tri-metallic 10 nm Au/40 nm Ag/10 nm Au nanolayers. The  sensors are tested with Pb(II) ion solution of concentrations 0.1 to 5 ppm using SPR spectroscopy. The results show  that the CS-GO SPR sensor on the bimetallic Ag/Au gives a gradual shift in SPR angle from 0.1 to 1 ppm and slightly  linear from 3 to 5 ppm. Meanwhile, the CS-GO SPR sensor on the tri-metallic Au/Ag/Au nanolayers provides an  extended linearity range from 1 to 5 ppm with the highest shift in SPR angle of 1.8o. Additionally, the tri-metallic CS-GO SPR sensor also exhibits the greatest SNR of 0.25 as compared to 0.15 of the one on the bi-metallic nanolayers.  Thus, the studies prove that the tri-metallic Au/Ag/Au nanolayer is an effective and simple approach to improve the performance of a CS-GO SPR sensor for Pb(II) ion detection.

Authors: Sulaiman Abdul Hadi , Najamhuri Nur Maizatul Nadia , Sukor Muhd Amirul Hafizi , Ismail Aiman , Abdullah Fairuz , Jamaludin Md Zaini
Published: July 2021

This paper demonstrates a multiwavelength fiber laser (MWFL) with erbiumdoped fiber amplifier (EDFA) as gain  medium and Sagnac loop mirror interferometer as filter. Stable and flat lasing spectrum was achieved when highly  nonlinear fiber (HNLF) was inserted into the laser cavity. The number of lasing lines and extinction ratio (ER) was directly influenced by EDFA gain where at maximum setting, 14 lasing lines with ER of 19 dB were generated. The  stable and flat spectrum achieved spanned about 1.6 nm. This is due to the induced intensity dependent loss  mechanism in the cavity by adjusting the half-wave plate of the polarization controller in combination with the  HNLF. The MWFL output showed peak power variation of about 2.1 dB within 100 minutes of observation time.
