ABSTRACT

Student learning activities are activities or activities of students in learning in the form of activities with themselves or groups that are influenced by internal and external factors. Learning style is a way that students use to understand information so that it can be accepted easily. In learning physics, student activity is very necessary. So that learning in the classroom needs to be carried out according to the student's learning style in order to create an active learning atmosphere and students can easily understand the material presented. This study aims to determine the effect of learning styles on the activeness of learning Physics in students. This research is a type of qualitative research. The data collection technique used is interviews with informants, namely Physics subject teachers in class X. From the results of interview analysis, it is known that students of class X IPA SMAN 11 Muaro Jambi have a type of visual learning style. This is because students are more interested and faster to learn if they use video media by raising the latest issues in Physics learning. However, for student activity is low. From the results of the interviews, it is known that students are not actively involved in learning such as asking questions. The low level of student activity is caused by several factors. The use of models or learning methods that are in accordance with students' learning styles can help maximize the learning process. So that the learning process can run actively and planned and provide maximum results.

Hong Kong Chinese character psycholinguistic norms: ratings of 4376 single Chinese characters on semantic radical transparency, age-of-acquisition, familiarity, imageability, and concreteness
Authors: Su I-Fan , Yum Yen Na , Lau Dustin Kai-Yan
Published: August 2022

Several norms of psycholinguistic features of Chinese characters exist in Mandarin Chinese, but only a few are available in Cantonese or in the traditional script, and none includes semantic radical transparency ratings. This study presents subjective ratings of age-of-acquisition (AoA), familiarity, imageability, concreteness, and semantic radical transparency in 4376 Chinese characters. The single Chinese characters were rated individually on the five dimensions by 20 native Cantonese speakers in Hong Kong to form the Hong Kong Chinese Character Psycholinguistic Norms (HKCCPN). The split-half reliability and intra-class correlations testified to the high internal reliability of the ratings. Their convergent and discriminant patterns in relations to other psycholinguistic measures echoed previous findings reported on Chinese. There were high correlations for semantic radical transparency, imageability and concreteness, and moderate-to-high correlations for AoA and familiarity among subsets of items that had been collected in previous studies. Concurrent validity analyses showed convergence in predicting behavioral response times in various tasks (lexical decision, naming, and writing-to-dictation) when compared with other Chinese character databases. High predictive validity was shown in writing-to-dictation data from an independent sample of 20 native Cantonese speakers. Several objective psycholinguistic measures (character frequency, stroke number, number of words formed, number of homophones and number of meanings) were included in this database to facilitate its use. These new ratings extend the currently available norms in language and reading research in Cantonese Chinese for researchers, clinicians, and educators, as well as provide them with a wider choice of stimuli.
Ideal Kerker scattering by homogeneous spheres: the role of gain or loss
Authors: Yang Qingdong , Chen Weijin , Chen Yuntian , Liu Wei
Published: August 2022

We investigate how the optical gain or loss (characterized by isotropic complex refractive indexes) influence the ideal Kerker scattering of exactly zero backward scattering. It was previously shown that, for non-magnetic homogeneous spheres with incident plane waves, either gain or loss prohibit ideal Kerker scattering, provided that only electric and magnetic multipoles of a specific order are present and contributions from other multipoles can all be made precisely zero. Here we reveal that, when two multipoles of a fixed order are perfectly matched in terms of both phase and magnitude, multipoles of at least the next two orders cannot possibly be tuned to be all precisely zero or even perfectly matched, and consequently cannot directly produce ideal Kerker scattering. Moreover, we further demonstrate that, when multipoles of different orders are simultaneously taken into consideration, loss or gain can serve as helpful rather than harmful contributing factors, for the elimination of backward scattering.

Casson Fluid Convective Flow in an Accelerated Microchannel with Thermal Radiation using the Caputo Fractional Derivative
Authors: Marjan Mohd Daud  , Lim Yeou Jiann  , Sharidan Shafie  , Rahimah Mahat
Published: August 2022

The effect of the Caputo fractional derivative in unsteady boundary layer Casson fluid flow in an accelerated microchannel is investigated. In the presence of thermal radiation, the partial differential equations that governed the problem are studied. Using appropriate dimensionless variables, fractional partial differential equations are translated into dimensionless governing equations. The equations are then transformed into linear ordinary differential equations and solved analytically using the Laplace transform technique. These modified equations are then solved using the proper method, and the result is obtained in the form of velocity and temperature profiles using the Zakian’s explicit formula approach. The influence of essential physical parameters on velocity and temperature profiles is investigated using graphical diagrams created with Mathcad software. It is found that the velocity and temperature profile increase as fractional parameter, and thermal radiation parameter increase. As Prandtl number increase, both profiles are decreasing. This result is crucial for understanding the fractional system of Casson fluid in microchannel.

The protection of very important persons in Hungary – the legislation of personal protection from 1997 to the present day
Authors: Lippai Zsolt , Uricska Erna , Nagy Tamás
Published: August 2022

Aim: The aim of this study is to describe the transformation of the institutional system of personal protection briefly over the last twenty-five years and to outline the main legislative and personnel (in particular, the scope of very important persons) changes up to the present day.Methodology: Governmental law enforcement has been characterised by constant change over the last quarter of century. This process involved not only changes in tasks and authority, but also the transformation, dissolution and creation of institutions. Despite this fact, there are few areas of law enforcement that have undergone such a complex and extensive transformation as personal protection in Hungary. After the change of regime, between 1990 and 1996, the field closely followed democratic transformation in the spirit of reform efforts, but no profound reform was achieved as comprehensive legislation was not ready until 1997.Findings: After 2010, there were several organisational, operational and regulatory changes resulting in the loss of the unity of personal protection and the emergence of a parallel institutional network with different types of bodies and different functions. This process is interpreted as a kind of slow reform of the field, but it is debatable from several viewpoints.Value: The study highlights the fact that the designation or removal of protection for public managers, and the reorganisation of tasks and authority between bodies give the overall impression that the professionalisation of the field took place in recent years without any real sectoral strategy.

PERIPHERAL MONUMENTS: BOOK REVIEW OF THINKING DESIGN: BLUEPRINT FOR AN ARCHITECTURE OF TYPOLOGY BY ANDREAS LECHNER
Authors: McEwan Cameron
Published: August 2022

In Thinking Design: Blueprint for an Architecture of Typology Andreas Lechner reassesses the question of architectural typology in relation to design research, practice, and theory. The book is organised into three extended chapters, entitled: Tectonics, Type, and Topos. In dialogue with the text are drawings of 144 important buildings from ancient times to the twenty-first century, focused on civic typologies. Each of those typologies incorporates a suite of 12 examples drawn in neat line drawings at a consistent scale. An enclosed booklet features design theses extracts by twelve students of TU Graz that illustrate Lechner’s approach to teaching and design. I reflect on each chapter and argue that Thinking Design offers an original theoretical reflection on the status of the urban periphery and opens compelling questions about architecture and architectural design research as a practice of critical inquiry.
Extension of the Asfgrid for Correcting Asteroseismic Large Frequency Separations
Authors: Stello Dennis , Sharma Sanjib
Published: August 2022

The asteroseismic scaling relation, Δν ≈ ρ
0.5, linking a star’s large frequency separation, Δν, and its mean density, ρ, is not exact. Yet, it provides a very useful way to obtain fundamental stellar properties. Common ways to make the relation more accurate is to apply correction factors to it. Because the corrections depend on stellar properties, such as mass, T
eff, and metallicity, it is customary to interpolate these properties over stellar model grids that include both Δν, measured from adiabatic frequencies of the models, and the models’ stellar density; hence linking both sides of the scaling relation. A grid and interpolation tool widely used for this purpose, known as Asfgrid, was published by Sharma & Stello. Here, we present a significant extension of Asfgrid to cover higher- and lower-mass stars and to increase the density of grid points, especially in the low-metallicity regime.
The Behavior of HgMn Stars in the Far-UV—Paper 10: HD 174933A and HD 35548A
Authors: Monier Richard
Published: August 2022

The analysis of low and high resolution spectra of the chemically peculiar stars HR 7113 and HR 1800 recorded by the SWP camera on board the International Ultraviolet Explorer reveals no variations of the far-ultraviolet flux for spectra separated by 4 months and 3 days for HR 7113 and 1 day apart for HR 1800 respectively. The TESS lightcurve of HR 7113 suggests a period close to 6.46 days which is close to the orbital period previously determined. For HR 1800, a clear period is not seen, time intervals between successive maxima range from 5.53 to 5.82 days.
Callisto and Europa Gravity Measurements from JUICE 3GM Experiment Simulation
Authors: Cappuccio Paolo , Di Benedetto Mauro , Durante Daniele , Iess Luciano
Published: August 2022

The JUpiter Icy Moons Explorer is an ESA mission set for launch in 2023 April and arrival in the Jovian system in 2031 July to investigate Jupiter and its icy satellites with a suite of 10 instruments. The mission will execute several flybys of the icy moons Europa, Callisto, and Ganymede before ending the mission with a 9-month orbit around Ganymede. The 3GM experiment on board the spacecraft will exploit accurate range and Doppler (range-rate) measurements to determine the moons’ orbit, gravity field, and tidal deformation. The focus of this paper is on the retrieval of Europa’s and Callisto’s gravity field, without delving into the modeling of their interior structures. By means of a covariance analysis of the data acquired during flybys, we assess the expected results from the 3GM gravity experiment. We find that the two Europa flybys will provide a determination of the J
2 and C
22 quadrupole gravity field coefficients with an accuracy of 3.8 × 10−6 and 5.1 × 10−7, respectively. The 21 Callisto flybys will provide a determination of the global gravity field to approximately degree and order 7, the moon ephemerides, and the time-variable component of the gravitational tide raised by Jupiter on the moon. The k
2 Love number, describing the Callisto tidal response at its orbital period, can be determined with an uncertainty σ

k2 ∼ 0.06, allowing us to distinguish with good confidence between a moon with or without an internal ocean. The constraints derived by 3GM gravity measurements can then be used to develop interior models of the moon.
Seed predation and potential seed dispersers of the narrow endemic Ceratozamia norstogii (Zamiaceae)
Authors: Gómez-Domínguez Héctor , Hernández-Tapia Jessica , Ortiz-Rodriguez Andrés
Published: August 2022

In this study, we report the observation of potential seed dispersers of the endemic to Mexico and narrowly distributed Ceratozamia norstogii (Zamiaceae). Camera traps were installed in front of two plants of Ceratozamia norstogii and cone phenology until their maturity and disintegration was determined. The female cone of Ceratozamia norstogii has a development of ten months, from the time it emerges until it disintegrates. We were able to identify three stages of cone development: 1) Pre-pollination phase, 2) Pollination phase and 3) Seed maturation phase. Our results support an animal-dispersal hypothesis in Ceratozamia. Three mammals [a mouse (Pteromiscus sp.), a southern spotted skunk (Spilogale angustifrons) and a kinkajou (Potus flavus)] were recorded biting, carrying or removing seeds of Ceratozamia norstogii. The camera traps recorded no evidence of birds or other mammals coming to the cones to feed. Thus, interaction of frugivores with seeds occurs at night. The most frequent visitor was the mouse, followed by the southern spotted skunk and the kinkajou. Significant differences (GLM, p< 0.05) in visitor frequency and time for interaction were found between species. We believe that the mouse is probably the most effective seed disperser for Ceratozamia norstogii. The results presented here have evolutionary implications that can be scaled to the entire genus Ceratozamia. Specifically, short-distance dispersal promotes allopatric speciation in this group of plants.
Modeling Taxon Concepts: A new approach to an old problem
Authors: Pyle Richard , Bailly Nicolas , Remsen David
Published: August 2022

Although the biodiversity informatics community has recognized and understood the complexity of modeling information about scientific names and associated taxonomic concepts for more than three decades, many of the original questions and problems remain unresolved today. Because most biodiversity data is anchored to scientific names, and these names are governed by Codes of nomenclature, most effort and progress has focused on data structures centered around scientific names, rather than taxonomic concepts. But, as has been well documented in biodiversity data standards communities (e.g., Berendsohn (1995), Patterson et al. (2010), Pyle et al. (2021)), the relationship between the text-string scientific-name labels and the circumscribed conceptual taxa they are intended to represent is highly imprecise. Many attempts have been made to develop data models to represent taxonomic concepts as discrete, identifiable units to which biodiversity data can be linked. However, none has gained wide-spread adoption, often due to inherent subjective interpretations and the degree of taxonomic expertise required to define and interpret the individual units – aspects that limit their practical scalability. Similarly, previous efforts to develop taxon concept data models conflate properties of circumscription, classification, and nomenclature, resulting in overloaded notions of taxa that quickly become intractable. We describe an approach that mirrors centuries of actual taxonomic practice, rooted in fundamental properties of Code-regulated scientific names, which can leverage sources of existing digital information to represent taxonomic concepts in a highly structured, objective and computable way. It isolates the properties of circumscription from those of classification and nomenclature, but enables algorithmic integration of these three separate facets of taxonomic information using consistent informatic structures.
Binary or ternary mixture of solid dispersion: Meloxicam case
Authors: Sulaiman Hameed Ghaidaa , Basim Mohsin Mohamed Masar , Naji Sahib Mohanad
Published: August 2022

The present work was carried out to assess the value of adding water insoluble polymer to meloxicam amorphous solid formulation (ASD). Meloxicam was mixed with polyvinylpyrrolidone (PVP) (1:1 ratio) as a binary mixture and with PVP and ethyl cellulose (1:1:1 ratio) as a ternary mixture. Solvent evaporation method was used to prepare ASD formulations. The differential scanning calorimetry, powder X-Ray diffraction, Cambridge Structural Database and in-vitro dissolution were performed to assess the formulas. The results showed that the addition of insoluble polymer could prevent the recrystallization process during ASD formation. However, the binary mixture showed higher drug release percentage than the ternary mixture. Therefore, a rational amount of insoluble polymer could be considered to control recrystallization and manipulate drug release from ASD formulations.

Le télétravail vu par les dirigeants : un pas en avant, deux pas en arrière ?
Authors: Desmarais Céline , Dubouloz Sandra , Laborie Clara , Lacroux Alain , Borter Silna , Dima Justine , Nestea Paula
Published: August 2022

Le télétravail est considéré comme une innovation managériale majeure des dernières décennies. Elle serait toutefois sans doute restée encore longtemps marginale si elle ne s’était pas imposée lors des confinements institués au cours de la crise sanitaire récente. Une fois l’obligation passée, les résultats des enquêtes montrent que la route est encore longue avant que le télétravail ne soit intensément et largement adopté. Cette recherche vise donc à identifier les caractéristiques tant démographiques que psychologiques des dirigeants qui pourraient avoir une influence sur leurs choix actuels et à venir d’adopter durablement le télétravail au sein de leurs entreprises. Pour répondre à cette ambition, nous mobilisons un modèle conceptuel issu de la théorie des échelons supérieurs mais enrichi au prisme de la littérature sur les innovations managériales. À travers une enquête administrée à 119 dirigeants d’entreprises en Suisse Romande, nous montrons l’influence de certaines de leurs caractéristiques, telles que leur expérience (caractéristique démographique) mais surtout leurs représentations sociales du télétravail (caractéristiques psychologiques). En effet, leur opinion quant à la complexité du télétravail et de sa mise en œuvre, sa compatibilité avec l’activité de leur entreprise et leurs collaborateurs, leur attitude face au contrôle et leurs croyances concernant la confiance qu’ils peuvent ou pas avoir envers leurs collaborateurs freinent leur décision d’adopter le télétravail.

Published: August 2022

Au chapitre IX d’ En rade , un article relatant la découverte des ptomaïnes, molécules parfumées nées de la putréfaction des corps, fait rêver Jacques Marles à des temps où leur extraction industrielle renouvellera le lien aux morts. Des emprunts laissent penser que la source de cette vision est un ouvrage publié en 1886 par le chimiste Armand Gautier. Dans ce compte rendu de recherches, Huysmans a trouvé matière à une critique visionnaire des technosciences. Par-delà la fumisterie désopilante, elle montre comment la méthode scientifique, liée à une conception dé-finalisée du vivant, induit une perte de repères et l’éveil de pulsions archaïques destructrices. Mais l’intérêt des cadavres exquis de Gautier est aussi littéraire ; en consonance étroite avec la poétique baudelairienne, ils annoncent, entre science et littérature, la « poésie objective » de Rimbaud et des surréalistes.
Positive XVAs
Authors: Crépey Stéphane
Published: August 2022

Since the 2008 crisis, derivative dealers charge to their clients various add-ons, dubbed XVAs, meant to account for counterparty risk and its capital and funding implications. As banks cannot replicate jump-to-default related cash flows, deals trigger wealth transfers and shareholders need to set capital at risk. We devise an XVA policy, whereby so called contra-liabilities and cost of capital are sourced from bank clients at trade inceptions, on top of the fair valuation of counterparty risk, in order to guarantee to the shareholders a hurdle rate \begin{document}$ h $\end{document} on their capital at risk. The resulting all-inclusive XVA formula reads (\begin{document}$ {{{\rm{CVA}}} }+{{{\rm{FVA}}}}+{{{\rm{KVA}}}} $\end{document}), where C sits for credit, F for funding, and where the KVA is a cost of capital risk premium. All these XVA metrics are portfolio-wide, nonnegative and, despite the fact that we include the default of the bank itself in our modeling, they are ultimately unilateral. This makes them naturally in line with the requirement that capital at risk and reserve capital should not decrease simply because the credit risk of the bank has worsened. An application of this approach to a dealer bank reveals, in particular, the XVA implications of the centrally cleared hedging side of the derivative portfolio of the bank.
Adaptive fuzzy output-feedback event-triggered control for fractional-order nonlinear system
Authors: Wang Chaoyue , Ma Zhiyao , Tong Shaocheng
Published: August 2022

This paper studies the issue of adaptive fuzzy output-feedback event-triggered control (ETC) for a fractional-order nonlinear system (FONS). The considered fractional-order system is subject to unmeasurable states. Fuzzy-logic systems (FLSs) are used to approximate unknown nonlinear functions, and a fuzzy state observer is founded to estimate the unmeasurable states. By constructing appropriate Lyapunov functions and utilizing the backstepping dynamic surface control (DSC) design technique, an adaptive fuzzy output-feedback ETC scheme is developed to reduce the usage of communication resources. It is proved that the controlled fractional-order system is stable, the tracking and observer errors are able to converge to a neighborhood of zero, and the Zeno phenomenon is excluded. A simulation example is given to verify the availability of the proposed ETC algorithm.
La violence cartographique au cœur de la relation entre l’État et les autochtones en Argentine
Authors: Preci Alberto
Published: August 2022

Cet article étudie la violence qui caractérise la relation entre l’État et les peuples autochtones en Argentine au prisme de la production cartographique institutionnelle. En mobilisant la notion de « violence cartographique », l’article montre comment les logiques d’exclusion et d’invisibilisation des autochtones ont été rendues en cartes et « en vrai », et comment cela a constitué une logique de fond, toujours d’actualité, de la construction de l’Argentine moderne. L’analyse d’un corpus de trois cartes, réalisées entre 1901 et 2016, qui représentent la portion du Chaco argentin correspondant à l’Est de la province de Salta, révèle le maintien et la reproductivité des stratégies institutionnelles de domination des autochtones, malgré un contexte socio-politique en pleine évolution.
Território-currículo: uma travessia da docência-epidérmica
Authors: Rochefort Carolina Corrêa , Garcia Maria Manuela Alves
Published: August 2022

O ensaio, desde o ponto de vista da Filosofia da Diferença e de teóricos da educação e do currículo, problematiza a prática de uma docência-epidérmica de uma professora-artista num Centro de Artes de uma universidade pública. Desenvolvendo o pensamento acerca de um currículo-epidérmico enquanto território nômade e superfície de atravessamento, defende a possibilidade de a docência-epidérmica fazer rasgos nas grades curriculares e inventar traçados inesperados e singulares. Tematiza o currículo enquanto território que articula camadas estriadas e lisas e convida a uma travessia-epidérmica cujo movimento acontece num espaço intermezzo. Uma travessia que pedagogicamente privilegia os acontecimentos e a criação de conceitos, que se faz pela desterritorialização e a reterritorialização, pondo o conhecimento em movimento, interpelando estados e tocando os corpos. Nessa travessia importam os atravessamentos, a experiência que inventa outros modos de existência.

Published: August 2022

Investiga-se como o princípio da interdisciplinaridade se faz presente no “quefazer” e reflexões de docentes, egressos de curso de licenciatura organizado por área do conhecimento, tendo por base os estudos de Freire (2010) Japiassu (1976), Fazenda (1981), dentre outros que conduzem pesquisas relacionadas à temática interdisciplinaridade. A pesquisa descritiva, de abordagem qualitativa, foi realizada a partir de questionário on-line, transcrição de uma Roda de Conversa Virtual e anotações das pesquisadoras. Os achados foram apreciados por Análise Textual Discursiva (Moraes; Galiazzi, 2011) e apontaram reflexões e concepções sobre a importância da interdisciplinaridade na licenciatura em Ciências da Natureza, além do desafio de aplicar a interdisciplinaridade na prática profissional. Por fim, sinaliza-se para a necessidade de estudos e diálogos sobre a interdisciplinaridade na prática pedagógica.

O curso de licenciatura em Ciências da Natureza da Universidade Federal do Vale do São Francisco, Campus Senhor do Bonfim-BA, foi implantado em agosto de 2009, no âmbito do Programa de Reestruturação e Expansão das Universidades Federais, e reestruturado em 2017, para contribuir com a formação de professores de Ciências da Natureza. Desde sua gênese, a interdisciplinaridade constitui fundamento de seu currículo, que tem como eixo integrador a educação em ciências. Através da análise de conteúdos de documentos e questionários, discute-se ações docentes que buscam transcender a disciplinaridade, refletindo sobre o impacto dessas ações na formação dos licenciandos.
O curso de licenciatura em Linguagens e Códigos/Música: a perspectiva interdisciplinar na prática pedagógica docente
Authors: Utta Bergson , Gonçalves Rocha Maíra Teresa
Published: August 2022

Este artigo objetiva refletir sobre a perspectiva interdisciplinar do curso de Licenciatura em Linguagens e Códigos/Música (LLC-MUS) da Universidade Federal do Maranhão. Em oferta desde 2010, ela contempla aspectos fundamentais para estudantes, evidenciando ser um processo de articulação de saberes em oposição a uma visão cartesiana e mecanicista de educação, revelnado ser mais integradora e dialógica para a constituíção do conhecimento. Nessa busca, contamos as contribuições de Morin (1999), Petraglia (1993) e Fazenda (2002, 2008). Nossa metodologia, sob os procedimentos técnicos, é bibliográfica, partindo da reflexão do Projeto Pedagógico do Curso e depois sobre as interlocuções dos docentes quanto a perspectiva interdisciplinar, concatenando com as discussões teóricas acerca da interdisciplinaridade. Inferimos que, quando existe a compreensão da perspectiva interdisciplinar na prática pedagógica docente, ensinar e aprender tomam novos rumos, favorecendo os sujeitos envolvidos.
Can Music Save Lives?
Authors: Guerra Paula
Published: August 2022

Against the background of the global COVID-19 pandemic, this chapter presents an in-depth vision of the relationship between music-making and the domestic life of Portuguese artists. The chapter presents and discusses data from an international project related to the Portuguese reality. Then, on the basis of some 40 semi-structured interviews with Portuguese musicians, the author reflects on the impacts of the pandemic on their musical careers and potential impacts on music-making processes more generally, as well as on family and domestic life. Finally, the chapter highlights the scarcity of this kind of research in the Portuguese reality, making it imperative that other dimensions of music-making and artists' lives are explored and made perceptible, not just the economic losses suffered.

Published: August 2022

The emerging field of interpersonal emotion regulation (IER) is drawing attention to forms of emotion regulation which involve communication and social interaction as part of the regulation process. The availability of instruments to measure IER in different languages represents significant promise for future work in this field. The goal of the present study was to validate an Italian adaptation of a self-report instrument for the assessment of IER, the Interpersonal Emotion Regulation Questionnaire (IERQ; Hofmann et al., 2016). In an Italian sample (N=448), exploratory and confirmatory factor analyses confirmed the original structure comprising four factors (Enhancing Positive Affect, Perspective Taking, Soothing and Social Modelling). Correlations with other measures of emotion regulation showed good convergent validity of the questionnaire.

Introduction:

Irradiation to the conserved breast consists of whole breast radiotherapy (WBRT) followed by tumour bed boost. Seroma in the tumor bed is a commonly observed side effects after breast-preservation, which can alter the shape of breast during WBRT and also lead to tumour bed shrinkage during boost irradiation, causing larger volumes of normal tissue irradiated. The aim was to evaluate the change in the lumpectomy cavity volumes before and after WBRT.

Materials and Methods:

Thirty-three patients with demonstrable lumpectomy cavity after breast conservation surgery (BCS) were included in the study. CT simulation of the breast was performed twice, initially before the start of WBRT and then 2 days prior to completion of WBRT. WBRT was delivered after contouring breast and lumpectomy volumes guided by the presence of surgical clips, seroma, and other surgical changes. Change in volume of lumpectomy cavity was analysed by Students’ paired T-test.

Results:

The volume reduction in the lumpectomy cavity was noted in 97% of patients (32/33). The change in lumpectomy cavity volume decreased by a mean value of 34.59% (range 0 - 72%) (p < 0.0001). The mean change in breast volume was 8.44% (range, -2.44 to 10.12%) (p - 0.394). Age, weight, location of tumour, T stage, breast volume, lumpectomy cavity volume, presence of clips and pre-radiation chemotherapy were not significantly associated with volume reduction of the lumpectomy cavity.

Conclusion:

The results of this study have shown that a significant volume reduction of the lumpectomy cavity after WBRT.
