«Violin» characteristics of Édouard Lalo’s «Symphonie Espagnole»
Authors: Oleksandra Onishchenko
Published: September 2022

Statement of the problem. An arsenal of technical performance means can act as an indicator of the novelty of a work at a certain historical stage, opening the way to understanding both evolutionary processes in the field of performance, in particular violin, and the patterns of development of certain genres. The purpose of the article is to highlight the issue of “violin” and “non-violin” specifics on the example of É. Lalo’s «Symphonie Espagnole» (Violin Concerto No. 2, op. 21), which belongs to a number of violin concertos of the last third of the 19th century marked by the influence of a new wave of virtuosity. The question of “non-violinism” became relevant in the late 70s of the 19th century, when the concert repertoire was replenished with works that went beyond the performance ideal as a result of the composers’ rethinking of the principles of musical dramaturgy and, accordingly, the functions of the soloist and the orchestra. Subordinating technical tasks to the dramaturgy of the work, rather than showing the virtuoso capabilities of the instrument and the soloist, raises a number of issues related to the objective perception of the new sound artistic model. Thus, in the concert works for the violin of the last third of the 19th century, two approaches are evident – traditional and innovative. É. Lalo’s concert works, despite the presence of his name in scientific research, remain understudied. In particular, the approach to the analysis of the «Symphonie Espagnole» from the viewpoint of “violin” and “non-violin” characteristics has not been used before. Results and conclusions. The analysis of É. Lalo’s work according to several parameters proposed by us (the balance of solo and orchestral parts; the implementation of tessitura and dynamic tasks; the choice of strokes; techniques of playing – passage, chordal technique; fingering) with the purpose of identifying the specific “violin” nature in the musical text allowed us to come to the conclusion that the spread of the latest trends did not turn É. Lalo away from using purely violin techniques and artistically expressive means that maximized performance comfort. The evolution of the concert genre in the last third of the 19th century contributed to the emergence of a new format of the relationship between the soloist and the author, when the dramatic idea, the artistic content of the work became a priority in the composing process, and the transformation of the performance approach towards the subordination of the soloist to certain semantic dominants expanded the limits of performance possibilities. However, musicians did not reject the traditional approach; they preserved the continuity of performance traditions, which is proved by the works of É. Lalo, A. Dvořak, C. Saint-Saëns.
Performance Chronotope in the Piano Sonatas by Beethoven (op. 27 No. 2) and Schubert (D. 958)
Authors: Anatolii Tarabanov
Published: September 2022

The article examines the specifics of the performance chronotope (time-space) of two masterpieces written by outstanding composers-contemporaries, whose lifetime is characterized by a gradual transition from the classical to the romantic style. Its essential characteristics and the significance of their awareness by the pianist-performer in the practice of working at a musical piece are highlighted. The “performance chronotope” is one of the parameters involved in the field of contemporary music-performance interpretation (Nikolaievska, 2020: 144). This publication is related to our previous work, where space-time characteristics of clavier sonatas by D. Scarlatti, С. Ph. E. Bach, J. Haydn, W. A. Mozart, and M. Clementi were revealed from the viewpoint of a piano performer (Tarabanov, 2021). Some parameters of the performance chronotope that have been outlined before – interaction and mutual balance of statics and dynamics, organizing function of performance time in sound musical form, metrorhythmic performance inertia, continuity of space-time and performance prediction (anticipation) – are supplemented by others, such as performance understanding of the form through working at details, and psychological space-time of the performer (as one of the components of the performance chronotope of the work). This is attributable to new interpretative tasks of the pianist in Beethoven’s and Schubert’s Sonatas under consideration. These works have not yet been the subject of analysis from the standpoint of performance chronotope characteristics, which, along with the use of an experimental research method (with the involvement of the author’s experience in concert performance of the considered works10), determined the scientific novelty of the presented study. The results of the study are supposed to be helpful for piano performers in their learning of these works and similar ones. It is especially relevant, because the greatest composer of piano sonatas, Ludwig van Beethoven, is in the spotlight all the time. His so-named “Moonlight” Sonata (op. 27 No. 2) continues to attract new generations of listeners, performers, and researchers (Rosen, 2002; Waltz, 2007; Gordon, 2017, and others). Beethoven’s direct successor, Franz P. Schubert created no less fascinating works in the genre of piano sonata. Among them is the Sonata D. 958 in C minor, where Beethoven’s influence is observed to a great extent. As in the case with concrete musical examples analyzed in the article, the piano performer can realize on practice their own interpretative searches connected with the use of timespace characteristics. In particular, a method of “expanding the performance chronotope” is recommended, which should significantly facilitate the mastering of complicated technical episodes.
Grover Washington Jr.’s style of improvisation on the saxophone
Authors: Zhang Qi
Published: September 2022

Statement of the problem. Creativity of Gr. Washington Jr. studied, although he was a very popular performer and improviser. The official site provides the most detailed material on the heritage of Gr. Washington Jr., a section is not well of A. West’s dissertation (Aaron J. West) is devoted to the method of his improvisation, Gr. Washington Jr. is mentioned in studies on the theory and history of jazz (Aebersold, 1992; Ellenberger, 2005; Levine, 1995) as well as in a research essay on “smooth” jazz (Flynn, 2014; Mader, 2012). The purpose of the article is to outline the main features of Grover Washington Jr’s improvisation on saxophone. The research methodology combines several sources: works on the theory of improvisation (Ferand, 1957; Bailey, 1993; Stetsiuk, 2020; Zotov, 2018), works on performance style and interpretation as communication (Adorno, 2002, Nikolaevska, 2020). Based on a combination of methods, the article defines “style of improvisation” as a system of four dimensions: the phenomenological considers improvisation as a method of music-making based on the instantaneous transmission of what appears in empirical time; pragmatic – explores improvisation as a set of elements that are formed in the language of an individual musician and objectified “here and now” according to certain laws of form; personal – interprets improvisation from the standpoint of the psychological and spiritual qualities of a musician-improviser; communicative – studies improvisation from the point of communication between the musician(s) in the group and the musician(s) with the audience. The study uses this proposed definition to analyse Gr. Washington Jr’s works. Scientific novelty is declared by the analysis of “style of improvisation” as a system of four dimensions (phenomenological, pragmatic, personal and communicative). Conclusions and results of the study. The article revealed the features of Gr. Washington’s style of improvisation on the example of his albums “Inner City Blues” (1971), “Mister Magic” (1975) and “Winelight” (1980), which belonged to the crossover music of the 1970s and established musical and cultural paradigms of the smooth jazz in the 1980s. The pragmatic dimension of the style is evident in the saxophone timbre (“multi-timbre” instrument); modal harmony (an evolution from a “two-chord vamp” to richer harmonic thinking, from smooth jazz to fusion); predominantly “horizontal” melodic thinking; tendency to build short phrases. The communicative dimension is expressed in the predominance of the declamatory (recitative) style of jazz improvisation, which returned jazz to the traditions of the swing era, phenomenally manifesting itself in the work of Washington and influencing the further development of jazz.
Performing peculiarities of interpretation of V. Podgorny’s works for button accordion (based on the Fantasia on the theme of the Ukrainian folk song “Poviy, vitre, na Vkrayinu”)
Authors: Oleksandr Lytvyshchenko
Published: September 2022

V. Podgorny made a great contribution to the development of the national button accordion art of the second half of the twentieth century. The composer managed to create highly artistic works that reflect the dramatic content and characterize the author’s symphonic thinking. The article reveals the peculiarities of the performer’s interpretation of works for button accordion by V. Podgorny on the example of Fantasia on the theme of the Ukrainian folk song “Poviy, vitre, na Vkrayinu”. For this purpose, for the first time, two performance versions by two famous performers are analyzed: a version by O. Nazarenko, and a version by F. Lips. The conclusions emphasize that the interpretation of V. Podgorny’s works requires accurate knowledge of the text, correct nuances, a good command of strokes; skillful pedalization and sound production, vocalization of melody when conveying the image.

Published: September 2022

Key Points

Proximal tubular secretion is a primary kidney function not reflected by GFRs.

Secretion is rarely measured due to a paucity of validated markers. This study uses metabolomics to identify candidate endogenous solutes.

Solutes were compared with the clearance of furosemide and penciclovir, two highly secreted medications, in 50 patients with and without CKD.

Background

The proximal tubules eliminate protein-bound toxins and drugs through secretion. Measurements or estimates of GFR do not necessarily reflect the physiologically distinct process of secretion. Clinical assessment of this important intrinsic kidney function requires endogenous markers that are highly specific for secretory transport.

Methods

We used metabolomics profiling to identify candidate markers of tubular secretory clearance in 50 participants from a kidney pharmacokinetics study. We measured metabolites in three sequential plasma samples and a concurrent 10-hour timed urine sample using hydrophilic interaction liquid chromatography/high-resolution mass spectrometry. We quantified the association between estimated kidney clearance and normalized plasma peak height of each candidate solute to the clearance of administered furosemide, a protein-bound, avidly secreted medication.

Results

We identified 528 metabolites present in plasma and urine, excluding pharmaceuticals. We found seven highly (>50%) protein-bound and 49 poorly bound solutes with clearances significantly associated with furosemide clearance and 18 solute clearances favoring an association with furosemide clearance by the 90th percentile compared with GFR. We also found four highly bound and 42 poorly bound plasma levels that were significantly associated with furosemide clearance.

Conclusions

We found several candidate metabolites whose kidney clearances or relative plasma levels are highly associated with furosemide clearance, an avidly secreted tracer medication of the organic anion transporters, highlighting their potential as endogenous markers of proximal tubular secretory clearance.
Psychological Expression in Free Verse

In the context of the transformation of poetic literature from traditional poetry into new poetry, many other new genres of literature have also emerged. Creation is not only determined by the Creator. The social events that he observes in this society have an impact on him. He creates his own literature based on them. At the same time, the socio-political changes taking place in their society bring about a few changes in their traditional tendencies. The British rule in India is the best example. The British who came here introduced their literary forms here. Its impact slightly changed the creative tradition of the creators here. While this change is necessary for the readers of the work, it has become constant. These methods of creation were of great use to make it easier for the ordinary reader to understand ideas that were to be understood by the common man or for ordinary people to understand. In the context of the inability to read or understand the old poems without commentators, a new poetic tradition was greatly needed, and it was this necessity that developed the new poetry.

Authors: S Uma , T Kamali
Published: September 2022

Social anthropologists have given various interpretations and definitions of culture. Culture is interwoven into the domestic as well as the public life of the people of the Sangam age. The culture of the people of Marutham land depended on agriculture. The people who lived in fertile agricultural lands lived by the disciplines that they could follow. Marriage is considered important and primary in Tamil culture. The Akananooru songs talk about the rituals of marriage. It is understood that "Silambu Kazhi Nonbu" (removal of anklets put on by the parents before the marriage of the girls) was the main ritual in the wedding rituals. The wedding rituals were simple. It is mentioned in the Kalitthokai that wearing new clothes at the time of the wedding, wearing new ornaments, adorning with garlands of flowers, and circumambulating the fire as guided by the Brahmin during the time of the wedding.

Published: September 2022

Aims. To develop an algorithm for assessing the stage of ﬁbrosis based on high-density endocardial mapping. To study the eﬀect of the stage of left atrial (LA) ﬁbrosis on the results of atrial ﬁbrillation (AF) catheter ablation.

Methods. The study included 64 patients with paroxysmal or persistent AF, who underwent high-density LA mapping and catheter ablation. After the intervention procedure, we analyzed the electroanatomical maps of the left atrium, assessed the prevalence of low-voltage areas according to the developed algorithm. Patients were divided into 4 groups depending on the prevalence of areas of low voltage based on the Utah score.

Results. The follow-up period was 14.5 ± 6.7 months. AF recurrence developed in 18 (28.1%) patients after the ablation procedure. AF recurrence after ablation was more frequent in patients with a low-voltage area of more than 20% than in patients with a low-voltage left atrial area of less than 20%, 6 (15.4%) versus 12 (48%), p=0.02. A logistic regression analysis was performed to identify AF recurrence predictors in the postoperative period. As a result, only widespread areas of low-amplitude activity were an independent predictor of AF recurrence after the pulmonary veins isolation, this predictive model was signiﬁcant (p=0.026). Signiﬁcant statistical diﬀerences between groups I, II and III,I V are the ejection fractions and the duration of the P-wave. Patients with low-voltage regions have lower left ventricular ejection fraction (62.8±6.9% versus 58.1±5.7%, p=0.01), and longer P-wave duration (84.7±8,2 ms versus 101.5±11.0 ms, p=0.01).

Conclusion. LA high-density mapping before AF ablation makes it possible to determine the prevalence of low-voltage areas. After regression analysis, it was proved that common low-voltage areas are an independent predictor of AF recurrence after pulmonary vein isolation. Patients with low-voltage areas of more than 20% of the LA surface have longer P-wave duration and lower left ventricular ejection fraction.

Published: September 2022

The reduction in conventional fuels consumption can be accomplished through the use of solar energy, transforming it into thermal energy throught a solar collector. There are a lot of solar collector kind, but the solar concentration way, specifically the parabolic dish reflector technology, or just PDR solar concentrator, offers one of the most efficient paths to achieve high quality thermal energy. Usually, the PDR solar concentrator are designed in big dimensions in order to generate electrical energy; nevertheless this technology could be used in minor scale in order to generate solar concentration high levels to achieve enough thermal energy to satisfy hot water demand in residential buildings, homes and even the industry. The prototype here presented was developed in four phases: The parabolic dish, the gear box and mechanical support device, the sun tracking control system and finally the system integration and operational tests. The four phases conjunction results in a totally operative prototype with the capability of achieve temperatures of 400 ºC, over a concentration focal point under partially cloudy day conditions.

Published: September 2022

El objetivo de este artículo es identificar de qué manera se realizan estrategias que apoyen el mercadeo educativo y la reputación corporativa desde el docente, en siete universidades acreditadas, privadas y públicas de Medellín-Colombia. Se utilizó una metodología mixta, con entrevistas a profundidad a los directores de mercadeo de las universidades acreditadas y 231 encuestas a docentes internos de los departamentos de administración de las mismas universidades, teniendo como base para su intervención el modelo AFC (análisis factorial confirmatorio) y el modelo de ecuaciones estructurales. Se evidenció dentro de los resultados que la gestión del mercadeo ha ganado importancia en la planeación estratégica de las universidades y que de esta manera se han logrado incluir algunos stakeholders para generar más confianza, satisfacción y lealtad, con el fin de construir una mejor reputación corporativa al interior y exterior de la comunidad académica. Se concluye que los docentes, en su mayoría, se sienten satisfechos con las funciones que realizan, y que esto les permite una mayor motivación al momento de interactuar con los públicos. Sin embargo, se evidencia que pocos se sienten incorporados con las estrategias de mercadeo que se desarrollan en las universidades, lo cual puede afectar la identidad, imagen y posicionamiento de estas.

Данное устройство испытали на наблюдательных скважинах водозабора «Авачинский» Елизовского месторождения питьевых подземных вод (Камчатский край). Результаты измерений температуры воздуха в скважине показали, что теплоизоляционный кожух предотвратил возникновение отрицательных температур внутри наземной части скважины. Это обеспечило надежное функционирование элементов питания телеметрической станции в осенне-зимний период. Защитный чехол в период испытаний обеспечил защиту теплоизоляции от воздействия ультрафиолетового излучения и влаги.

The authors of the article have developed a unified head of an observation well of drinking groundwater deposits, equipped with telemetric transmitting stations. This device was tested in the observation wells of the Avachinsky water intake of the Elizovski deposit of drinking groundwater (Kamchatka Krai). The results of measurements of the air temperature in the well showed that the thermal insulation casing prevented the occurrence of negative temperatures inside the ground part of the well thus providing for the reliable functioning of the power cells of the telemetry station in the autumn-winter period. A protective cover provided for the protection of the thermal insulation from the impact of ultraviolet radiation and moisture during the testing period.
Different helicity dependency of all-optical magnetization switching in GdFeCo films with optical interference layer
Authors: Yoshikawa Hiroki , Tajima Daiki , Kasatani Yuichi , Tsukamoto Arata
Published: September 2022

We observed helicity-dependent all-optical magnetization switching (HD-AOS) phenomena in GdFeCo films, which have equivalent magnetic properties but different optical properties due to optical interference layer thickness. Consequently, we found that these films have different properties of HD-AOS with the duality relation between magnetization direction and light helicity in light absorption, which generally means magnetic circular dichroism (MCD). Therefore, we also evaluated the effective absorption of the same GdFeCo samples which have similar intrinsic MCD by CW laser and intense femtosecond laser pulses. We confirmed that the contribution of this duality relation is much smaller in the absolute value of absorption. Furthermore, the magnitude and the sign of the duality relation change by the interference layer’s thickness. As a result, we concluded that the duality relation in HD-AOS is derived from the duality relation in absorption. Furthermore, its duality relation can be changed effectively using multiple interference effects.

Published: September 2022

Silicon carbide (SiC) was coated onto carbon nanowall (CNW) scaffolds using chemical vapor deposition with a vinylsilane precursor at 700 °C to investigate the influence of the wall edge width, wall-to-wall distance, and surface morphology. The wall edge width ranged from 10 nm to those filling the wall-to-wall space without disrupting the CNW morphology. When SiC-coated CNWs (SiC/CNWs) were used as scaffolds for cell culture, cell viability increased until the edge area ratio reached 40%. In over 40% of edge area ratio, cell viability was saturate and comparable to flat surfaces such as SiC films on the Si substrate (SiC/Si) and control samples prepared using polystyrene. Calcification was suppressed in the CNWs, SiC/CNWs, and SiC/Si scaffolds compared to polystyrene. Our results suggest that SiC-coated CNW scaffolds could suppress calcification and promote cell proliferation.
Co-planar waveguide ferromagnetic resonance spectroscopy of cobalt/platinum superlattice metamaterials
Authors: Tomita Satoshi , Kikuchi Nobuaki , Okamoto Satoshi
Published: September 2022

We study cobalt/platinum (Co/Pt) superlattices by means of ferromagnetic resonance spectroscopy in the frequency domain. The magnetization easy-axis of superlattices, which lies in a plane of the film with Co layers of 1.5 and 1.2 nm thickness, changes to the direction perpendicular to the film surface with Co layers of 0.9 and 0.6 nm thickness. As the Co layer thickness decreases from 0.9 to 0.6 nm, the Gilbert damping parameter significantly increases while the g-value is almost constant. As the Pt layer thickness decreases from 0.6 to 0.3 nm in the superlattices with 0.9 nm thick Co layers, the damping parameter slightly decreases. The present study demonstrates that the Co/Pt superlattices with 0.9 nm thick Co layers and 0.3 nm thick Pt layers are suitable for time-varying magnetic metamaterials realizing a larger magnetic permeability modulation.

AISI 316L stainless steel materials of thickness 3 mm have been united by tungsten inert gas (TIG) welding in square butt joint configuration as per Box-Behnken design technique of response surface methodology (RSM) to indentify the effects of input parameters on the quality of the TIG welded joints. The output responses have been measured after experimentation. Mathematical correlation between input parameters and output responses has been developed using RSM. The factors which influences on responses have been analyzed by generating the response surface and contour plots. Desirability function analysis (DFA) is employed for finding optimum parametric setting to achieve the most favourable mechanical properties. Microstructures of welded samples are also investigated to correlate the metallurgical-mechanical characteristics of the welded specimens. The result indicates that at the intermediate values of welding parameters create fine grain structure and superior mechanical properties.

Published: September 2022

The maternal mortality rate in Indonesia of 305/100,000 live births is still far from the SDGs target in the year 2030, which is 70/100,000 live births. The WHO states that the main causes of maternal mortality are bleeding, infection, preeclampsia-eclampsia, complications of childbirth, and unsafe abortion. This can be prevented if the mother can access health services, especially the use of skilled birth attendants to overcome complications of pregnancy and childbirth. This study aims to determine the factors associated with the use of skilled birth attendants in Indonesia. This cross-sectional study with a total sample of 4.543 women aged 15-49 years who gave birth to the last child selected in a sample of secondary data Indonesia Demographic Health Survey (IDHS) 2017. The dependent variable of the study was a skilled birth attendants and the independent variable was sociodemographic factors (age, education, employment, area of residence), antenatal factors (antenatal care examiner, antenatal place, antenatal frequency), medical factors (pregnancy complications and birth complications). The results of this study indicate that the dominant factor in the selection of skilled birth attendants is pregnancy examiners. Pregnancy examiners who examine the pregnancy by an obstetrician have the opportunity to choose a permanent delivery at an obstetrician, which is 8.33 (95% CI 6,75 – 10,29) times compared to choosing a midwife after being controlled by other variables.
DEGREE OF CORRECTION IN BUNION USING DYNAMIC SPLINTS
Authors: Rehman Zia , Shahid Osama
Published: September 2022

Background. Hallux valgus   or   bunions   the   most   widely recognized   issue of   the forefoot in grown-ups (1). The deformity of   Hallux valgus  is  reformist,  and  includes  a  few phases, yet  starts  with lateral  deviation  of  the  big  toe  (Hallux)  and  medially deviation  of  the  first  main  metatarsal  bone. An  Hallux  valgus  angle  more prominent  than  15  degrees  is  viewed  as  unusual  yet  at  such  a point  the proximal  phalanx  may  in  any  case  be  consistent  with  the  metatarsal  head   when seen on radiographs.(2) The  cause  of  Hallux  valgus  has  been  a  discuss topic  for  years,  but  is  likely associated  with  genetic  predisposition,  restrictive footwear,  other  foot  deformities  such  as  pronation  of  the  hind  foot furthermore, (pes planus, hyper mobility,  contracture  of  the  Achilles  ligament , and neuromuscular  problems,  for  example,  cerebral paralysis  and  stroke(3). Orthoses have been proposed to lessen the raised plantar weight under the medial ray in patients with  Hallux  Valgus  or  bunion  and  diminish pain (7,8) when joined with  a  toe separator, orthosis  may  likewise  assist  with  remedying  alignment. Preventing   general disability and  halting  the  progression  of  structural  changes  are  important  for  the management  of hallux valgus. Objectives. To evaluate the  clinical  effects  of  dynamic  splints  on  Hallux  valgus  this study was  performed. To  measure  the  degree  of  correction  that  can  be  achieved  using  the dynamic  splints. Methods. Sample size was 8. Hallux valgus patients with age from 15-60 years, Mild, moderate Hallux Valgus, Hallux valgus angle < 40 degree, Both genders. Results. Total sample size was 8, in which 6 (75%) were Female and 2 (25%) were males, and they all are from Peshawar. Total sample size was 8 and Mean of the angle before using the splint is (20.75) and standard deviation among the angle was (2.315). Total sample size was 8 and Mean of the angle after using appliance for 15 day was (19.88) and standard deviation of the total population was (2.58), while the correction achieved in degree of angle has a mean of (1.00) and standard deviation of (0.535). Data was recorded and analyzed through SPSS. Conclusion. The persistence of  the  effect  of orthosis  is  another  point  which  could  be assessed  by  evaluating  changes  during the wash-out  period. The fact  is  that  the  angular  changes  are  related  to  the  time  when  orthosis  is  worn,  so   these  changes  were  returned  to  first  state  by  doffing  the  orthosis.

Published: September 2022

In this work, a proof of concept for 5G-compliant user-equipment side sensing is presented. It is based on orthogonal frequency division multiplexing radar-based ranging which is realized in this work by using the sounding reference signal from the 5G New Radio standard. The signal configuration and thus the corresponding waveform is generated in compliance with the existing 3rd Generation Partnership Project standard for 5G. It is an uplink physical signal and is originally intended, amongst others, for channel estimation. The used model is introduced, followed by the sounding reference signal. This leads to a first proof of concept by presenting simulation and measurement results. We show, that a range estimation error in the order of centimeters is achievable.

Published: September 2022

Modern distribution networks are undergoing several technical challenges, such as voltage fluctuations, because of high penetration of distributed energy resources (DERs). This paper proposes a deep reinforcement learning (DRL)-based Volt- VAR co-optimization technique for reducing voltage fluctuations as well as power loss under high penetration of DERs. In addition, the proposed approach minimizes the operational cost of the grid. A stochastic policy optimization based soft actor critic (SAC) agent is proposed to configure the optimal set-points of the reactive power outputs of the inverters. The performance of the proposed model is verified on the modified IEEE 34- and 123-bus systems and compared with a base case scenario with no reactive supply by inverters, and a local droop control approach. The results demonstrate that the proposed framework outperforms the conventional droop control method in improving the voltage profile, minimizing the network power loss, and reducing grid operational cost.

Japanese quince trees are grown as ornamental plants in Iran, in parks and in orchards close to stone fruit and pome fruit trees. Shoots of Japanese quince (Chaenomeles japonica) showing sunken brown canker symptoms were observed and collected near Sari, the center of Mazandaran province in the North of Iran, during the 2016 growing season. Gram negative bacteria isolated from symptomatic tissues were similar to Pseudomonas syringae pv. syringae (Pss) were pathogenic on Japanese quince and on quince (Cydonia oblonga) seedlings after artificial inoculation, and were re-isolated from diseased hosts. Phylogenetic tree construction using partial sequences of ITS and rpoD genes showed that the Japanese quince isolates were in the same clade as Pss strains. The isolates had ice nucleation activity, and the InaK gene was amplified successfully. According to the results of phenotypic and genotypic characteristics, genomic DNA fingerprinting using REP-PCR, BOX-PCR and IS50-PCR and isolation of total cell proteins, we conclude that Pss is the causal agent of canker of the Japanese quince trees. Therefore, Japanese quince is a new host for Pss causing bacterial canker on many different host plants.
An Analysis of Track Effects on Storm Surge Simulation
Authors: Wahiduzzaman Mohammad
Published: September 2022

This study investigates the effects of cyclone tracks on water levels during storm surges along the coast of Bangladesh. A numerical hydrodynamical model in Cartesian coordinates has been developed, where the developed equations are solved by a semi-implicit finite difference method. The boundary fitted grid technique is employed to rectangularized the physical domain. Along the north-east corner of the model, the Meghna River fresh water discharge is taken into account. A stable tidal regime over the region of interest is generated with the help of four major tidal constituents, namely M_2 (principal lunar semi diurnal), S_2 (principal solar semi diurnal), O_1 (principal lunar diurnal) and K_1 (principal lunar diurnal) along the southern open boundary of the outermost model. This previously generated tidal regime is used as the initial state of sea in order to obtain water levels due to the nonlinear interaction of tide and surge. Numerical experiments are made with the severe storm April 1991 and some hypothetical storm tracks. The simulated results with the real track are found to be in a good agreement with some observed and some reported data. The water levels are found to be greatly influenced by the hypothetical cyclone tracks.
Automatized visualization methods for the qualitative analysis of teachers' collegial discussions
Authors: Matta Corrado , Kaufmann Odd Tore , Ryve Andreas
Published: September 2022

In this paper, we discuss a set of procedures for the visualization of conversation data, based on machine learning and text mining algorithms. The methodological function of these visualization methods is to support (rather than substitute) humanistic and interpretive qualitative data analysis. The context of our methodological discussion is the study of teachers’ learning communities. Enabling collegial learning among teachers has been argued to play a pivotal role in both teachers’ professional development and students’ learning. The problem is that the interpretive study of collegial discussions among teachers, which are typically considered a fruitful context for the study of teachers' collegial learning, is both time-consuming and cognitively demanding. Several scholars have discussed the potential of including machine learning and text mining in the toolbox of qualitative data analysis as a way to analyze large qualitative data sets and solve the time demand problem. However, the literature discussing the use of machine learning and text mining for qualitative research typically conceives the algorithms as substitutes for the work of the researcher. These automatized approaches are introduced to categorize the data, substituting the researcher in the analysis process. In contrast, we discuss the potential rewards of using automatized methods to support the analysis of teachers’ collegial discussions. We introduce a set of visualization procedures based on semi-supervised topic modeling and supervised classification algorithms and discuss how these visualizations can provide additional elements useful for the analysis of collegial discussions. Whereas these visualizations do not substitute interpretive analysis, we argue that they can support researchers’ interpretations by reducing data, identifying patterns of interactions, and possibly, visualizing group-level learning.
