Large Displacement J-Integral Double Cantilever Beam (DCB) Test Method
for Mode I Fracture Toughness
Authors: Gunderson Joshua
Published: March 2021

The J-integral is used to develop an alternative double cantilever beam (DCB) test method
for the Mode I fracture toughness suitable for both small and large displacements. The current focus
is the experimental determination of the Mode I interlaminar fracture toughness of composite materials,
but the method is generally applicable to other similar tests and material systems, such as to the Mode
I fracture toughness of adhesives. A series of five identical specimens are tested to compare the
linear-elastic fracture mechanics method recommended by ASTM, which makes use of linear beam theory
with root rotation, large displacement, and end block corrections, with the new nonlinear-elastic
and elastic-plastic fracture mechanics method, which does not require these corrections. Experimental
results show excellent agreement between the two methods over a series of five tests of primarily
linear-elastic DCB specimens subjected to moderate to large displacements as defined in the ASTM
standard. Furthermore, an agreement is found between the results of the derivations for the two
methods being compared, whereby the large displacement equation for JIc presented
in this work is identical to the equation given by J. G. Williams (1987) and which he found to be
the true value of GIc. It is the true value of GIc that the
large displacement and root rotation correction factors were intended to approximate, and the
test method presented here allows for direct measurement of its parameters and evaluation. This
method has the added benefit that specimens can be primarily linear-elastic or nonlinear-elastic
at the crack tip and may extend to those that are elastic-plastic at the crack tip.
Novel Memristor Based True Random Number Generator
Authors: Stoller Scott
Published: March 2021

Random numbers are an important, but often overlooked part of the modern computing environment. They are used everywhere around us for a variety of purposes, from simple decision making in video games such as a coin toss, to securing financial transactions and encrypting confidential communications. They are even useful for gambling and the lottery.

Random numbers are generated in many ways. Pseudo random number generators (PRNGs) generate numbers based on a formula. True random number generators (TRNGs) capture entropy from the environment to generate randomness. As our society and our devices become more connected in the digital world, it is important to develop new ways to generate truly random numbers in order to secure communications and connected devices.

In this work a novel memristor-based True Random Number Generator is designed and a physical implementation is fabricated and tested using a W-based self-directed channel (SDC) memristor. The circuit was initially designed and prototyped on a breadboard. A custom Printed Circuit Board (PCB) was fabricated for the final circuit design and testing of the novel memristor-based TRNG. The National Institute of Standards and Technology (NIST) Statistical Test Suite (STS) was used to check the output of the TRNG for randomness. The TRNG was demonstrated to pass 13 statistical tests out of the 15 in the STS.

Published: March 2021

El objetivo de este artículo es mostrar los problemas de la filosofía de la ciencia que enfrentan los investigadores del cambio climático. El tópico de la carga teórica de la observación aparece dentro del campo como una indispensabilidad de modelos teóricos en la detección y atribución del cambio climático. La infra-determinación empírica de los modelos se acompaña de una incertidumbre de valores (de series instrumentales y datos proxy) y una incertidumbre estructural, relativa a la especificación de los acoplamientos y forzamientos radiactivos. Se examina, además, el realismo de los modelos globales en conexión con su calibración y las proyecciones climáticas.
Algunas reflexiones filosóficas a propósito del coronavirus
Authors: Jaramillo Juan Manuel
Published: March 2021

En la primera parte se propone una reflexión sobre el Coronavirus como una enfermedad calificada de ‘pandemia’ y que afecta sin distingos a todo el mundo rompiendo las barreras de los nacionalismos. Se examinan dos de las más importantes opiniones acerca del Coronavirus y sus efectos: la de Byung-Chul Han y la de Yuval Noah Harari. Se busca contrastar estos dos puntos de vista, destacando las ventajas y riesgos que se puedan derivar del control algorítmico indiscriminado de la los individuos (tecno-información), como de las ventajas y riesgos del control biológico y genético (bio-información). En la segunda parte se abordan los problemas ontológicos del Covid-19 para establecer si se trata de un biosistema vivo o inerte, al tiempo que se examina la enfermedad del Coronavirus como el estado de un sistema biológico, una persona, en función de los valores de ciertas funciones de conformidad con leyes ya establecidas. Se advierte del error categorial de confundir la causa de la enfermedad con la enfermedad misma.

Published: March 2021

Pithecellobium diversifolium Benth. é um arbusto nativo com vasta ocorrência nos estados do Nordeste brasileiro. O crescente interesse na propagação e no cultivo de espécies florestais nativas demanda informações básicas sobre as características biométrica e germinativas das suas sementes para sua propagação. Com isso, o objetivo do trabalho foi caracterizar as sementes e avaliar o processo germinativo de P. diversifolium submetidos a métodos de superação de dormência. O experimento foi conduzido no Laboratório de Produção Vegetal do Instituto Federal de Alagoas, localizado no município de Piranhas-AL, onde foram coletadas as sementes. Foi realizada a caracterização física das sementes, determinando-se o teor de água, o peso de 1.000 sementes, e o comprimento, largura e espessura das sementes. Foram utilizados cinco tratamentos para superação de dormência: (T1) intactas; (T2) escarificação mecânica com lixa d’água nº 80; (T3) fragmentação do tegumento; (T4) imersão em água a 90 °C por 1 min; e (T5) imersão em água por 24 horas. As avaliações do teste de germinação foram feitas diariamente, durante 26 dias. Os parâmetros avaliados foram primeira contagem de germinação; porcentagem de germinação; índice de velocidade de germinação; comprimento da parte aérea e da raiz principal; massa seca da parte aérea e raiz. O delineamento experimental utilizado foi o Inteiramente Casualizado com quatro repetições de 50 sementes por tratamento. Dessa forma, as sementes possuem variabilidade em suas características biométricas avaliadas, e a escarificação mecânica com lixa d’água é o método recomendado para superar a dormência das sementes de P. diversifolium.

Published: March 2021

Um dos principais metais explorados no mundo é o cobre (Cu), um elemento nativo, que dificilmente é encontrado puro na natureza. A lavra e beneficiamento do cobre geram debates ambientais devido à formação de agentes poluidores nas áreas de concentração, fundição e refino, além dos impactos negativos na vegetação e topografia da área minerada. Este trabalho teve como objetivo investigar o desempenho morfométrico inicial do ipê-branco (Tabebuia roseo-alba (Ridl.) Sandwith) em substrato composto por rejeito de mineração de cobre e percentuais crescentes de matéria orgânica, bem como, avaliar seu potencial fitorremediador e o Índice de Qualidade de Dickson (IQD). O delineamento experimental foi o inteiramente casualizado, onde se coletou dados morfométricos dos tratamentos referentes à altura, diâmetro do caule e número de folhas da espécie vegetal que posteriormente foram submetidos à análise estatística e ao IQD, além dos cálculos relacionados ao índice e fator de translocação do cobre na planta e sua capacidade fitoextratora. A fitomassa compartimentalizada em raízes e parte aérea foi coletada, colocada em estufa, moída e enviada ao laboratório para as devidas avaliações do metal cobre nos compartimentos da espécie vegetal, além da avaliação química do substrato. Concluiu-se que o ipê-branco possui potencial fitoestabilizador do elemento cobre proveniente de rejeito de mineração, bem como atingiu um IQD satisfatório no tratamento composto por 90% de rejeito de mineração e 10% de matéria orgânica.

Published: March 2021

BACKGROUND The most commonly done gynaecological surgery worldwide is hysterectomy. Myometrial lesions contribute to majority of cases with abnormal uterine bleeding. Leiomyoma and adenomyosis are most common lesions seen in the myometrium. The present study was undertaken to identify the various types of myometrial pathologies in hysterectomy samples. METHODS This is a two-year retrospective cross-sectional study done from January 2017 to December 2018, in the Department of Pathology, Kodagu Institute of Medical Sciences, Madikeri. All the patients who underwent hysterectomy and myomectomy for myometrial lesions of uterus were included in the study. Hysterectomy specimens showing secondaries, gross infection, massive haemorrhage and necrosis were excluded from the study. Gross appearance and microscopic pathology were noted and results were analysed. RESULTS In this study, 148 specimens were included. Age range was from 20 years to 65 years. Histopathological examination revealed that 58.25 % of myometrial lesions were present in the age group of 41 to 50 years followed by age group of 31 to 40 years. Histopathological examination done showed the following diagnosis in patients - leiomyoma (85.13 %), adenomyosis (8.79 %) and leiomyoma with adenomyosis (6.08 %). CONCLUSIONS The commonest histopathological lesion in myometrium was leiomyoma (85.13 %) followed by adenomyosis (8.79 %). It is mandatory to examine the hysterectomy specimens adequately to diagnose myometrial lesions. KEYWORDS Myometrium, Leiomyoma, Adenomyosis
Diagnostic Limitation and Outcome of Definitive Surgical Approach in Placenta Accreta Spectrum Disorders - A Prospective Case Series Study
Authors: Poddar Suman , Sharma Shilpi
Published: March 2021

BACKGROUND Placenta accreta spectrum (PAS) disorders have become an emerging obstetric issue associated with risk of massive obstetric haemorrhage on placental separation following delivery. Antenatal diagnosis is of utmost importance but miserably limited due to lack of imaging expertise in this issue. We wanted to evaluate antenatal diagnosis of PAS disorders and analyse the outcome of definitive surgical approach. METHODS This is a prospective case series analysis done in the Department of Obstetrics and Gynaecology, RG Kar Medical College & Hospital, Kolkata. In a series, we have discussed 10 cases dealt well in our institution in the last one year (pre-Covid-era). Main outcome measures were operative blood loss, bladder injury, high dependency unit (HDU) admission, component transfusion, and neonatal morbidity. RESULTS Imaging expertise for prenatal diagnosis of PAS disorders was found miserably limited where 7 out of 10 cases were diagnosed intra-operatively. During Caesarean section (CS), longitudinal fundal incision was given to take out the baby with blood loss even less than usual CS. Bladder injury was diagnosed in one occasion intra-operatively. Peripartum total hysterectomy without touching placental bed was done in all cases, where uneventful bladder dissection and bilateral internal iliac artery ligation minimised component transfusion (8 out of 10) and HDU support (5 out of 10). Neonatal outcome was good in cases of planned CS at 36 weeks (6 out of 10). CONCLUSIONS Clinical suspicion plays an important role in our scenario due to lack of imaging experience & expertise to diagnose PAS disorders. Planned Caesarean delivery at late preterm period in equipped centre in expert hands improves outcome of such cases. Peripartum total hysterectomy without touching placental bed is the most definitive (surgical) approach with sound post-operative recovery.

Ultra-large Optical Kerr Nonlinearity in 2D PdSe2 Dichalcogenide Thin Films for Integrated Nonlinear Photonics
Authors: moss david , wu jiayang
Published: March 2021

As a novel layered noble metal dichalcogenide material, palladium diselenide (PdSe2) has attracted wide interest due to its excellent optical and electronic properties. In this work, a strong third-order nonlinear optical response of 2D PdSe2 films is reported. We conduct both open-aperture (OA) and closed-aperture (CA) Z-scan measurements with a femtosecond pulsed laser at 800 nm to investigate the nonlinear absorption and nonlinear refraction, respectively. In the OA experiment, we observe optical limiting behaviour originating from large two photo absorption (TPA) in the PdSe2 film of β = 3.26 ×10-8 m/W. In the CA experiment, we measure a peak-valley response corresponding to a large and negative Kerr nonlinearity of n2 = -1.33×10-15 m2/W – two orders of magnitude larger than bulk silicon. In addition, the variation of n2 as a function of laser intensity is also characterized, with n2 decreasing in magnitude when increasing incident laser intensity, becoming saturated at n2 = -9.96×10-16 m2/W at high intensities. Our results show that the extraordinary third-order nonlinear optical properties of PdSe2 have strong potential for high-performance nonlinear photonic devices. Keywords: 2D materials, PdSe2 films, Z-scan technique, Kerr nonlinearity, nonlinear photonics.

Published: March 2021

Peripheral nerve entrapment syndromes of the upper extremities are well documented in musicians. Bowed string players are at risk for entrapment neuropathies in the upper extremities and are sensitive to mild neurologic deficits. The purpose of this study was to determine the presence
of median and ulnar neuropathies in both upper extremities of university cellists. Fourteen volunteer cellists (ages 18-32 yrs) were recruited from the Belmont University School of Music and the Vanderbilt University Blair School of Music orchestras. Subjects completed a history form, were
interviewed, and underwent a physical examination. Nerve conduction status of the median and ulnar nerves of both upper extremities was obtained by performing sensory, motor, and F-wave nerve conduction studies. After completion of the median and ulnar nerve conduction studies, the cellists
were instructed in upper extremity injury prevention exercises. Descriptive statistics of the nerve conduction study variables were computed using Microsoft Excel. These subjects had normal upper extremity neural and musculoskeletal function based on extensive evaluation, including a history,
physical examination, and nerve conduction studies. There was no evidence of median or ulnar neuropathy at or distal to the wrist, in the forearm, across the elbow, or in the arm of the tested subjects.

Peripheral nerve entrapment syndromes of the upper extremities are well documented in musicians. Pianists and keyboard players are at risk for entrapment neuropathies in the upper extremities and are sensitive to mild neurologic deficits. The purpose of this descriptive study was to
determine the presence of median and ulnar neuropathies in both upper extremities of university pianists. Nineteen volunteer male and female pianists (ages 18 to 33 yrs) were recruited from the Belmont University School of Music and the Vanderbilt University Blair School of Music. Subjects
completed a history, interview, and physical examination, and nerve conduction status of the median and ulnar nerves of both upper extremities was obtained by performing motor, sensory, and F-wave (central) nerve conduction studies. These subjects had normal upper extremity neural and musculoskeletal
function based on extensive evaluation, including a history and physical examination. When comparing the subjects' nerve conduction study (NCS) values with a chart of normal NCS values, all electrophysiologic variables were within normal limits for motor, sensory, and central (Fwave) conduction
values. However, comparison of median and ulnar motor and sensory latencies in the same and opposite hand demonstrated that 3 of the 19 pianists (16%) had early evidence of median neuropathy at or distal to the wrist. The other 16 subjects demonstrated normal comparison studies of the median
and ulnar nerves in both upper extremities.

Development and Assessment of an Incremental Fatigue Protocol for Contemporary Dance
Authors: Coutts Rosanne , Gilleard Wendy , Hennessy Michael , Silk Aaron , Williams Gary , Weatherby Robert P
Published: March 2021

Nine trained contemporary dancers performed a modality-specific, heart-rate-monitored, choreographed fatiguing dance protocol with an assumption of fatigue at volitional exhaustion (RPE 16). Postural stability was assessed as the variability of ground reaction forces and the centre
of pressure during the performance of a flat-foot arabesque. Psychological response was assessed using self-reported fatigue, psychological distress (PD), and psychological well-being (PWB) (Subjective Exercise Experience Scale). After reaching RPE 16 in 15.7 ± 2.6 mins, heart rate
decreased to the post-warm-up level within 64 ± 9 sec. Variability of ground reaction forces or the centre of pressure was not changed. There were no significant changes in fatigue, psychological distress, or psychological well-being. Within fatigue, there was a significant increase
in the item tired (p = 0.04). As supported by the heart rate data and RPE, the protocol achieved an appropriate level of physical demand. No changes in the stability indices were observed, possibly attributed to the rapid recovery in heart rate. The expression of only tiredness suggests
the use of a disassociative attentional style by the dancers. The project represents pilot work toward the validation of a monitoring process that supports dancer health and awareness training.
The Ring of Fire: Shame, Fame, and Rock 'n' Roll
Authors: Raeburn Susan D
Published: March 2021

A healthy sense of shame is a source of personal power—it acknowledges that to be human is to be limited, provides humility, connects one with his or her core dependency needs, and allows people to ask for help when necessary. Toxic shame, on the other hand, becomes a core identity
of worthlessness and a motivator of self-destructive and addictive behavior. Toxic shame is the byproduct of insecure attachments and shame-based family rules and systems and is transferred across generations unconsciously and procedurally via criticism, rejection, invalidation, verbal or
physical abuse, and other forms of emotional abandonment. This paper describes key psychological processes associated with shame and explores how they may interact with the business of popular music for musicians, using the publicly described life of Johnny Cash as a clinical example. Based
on the events depicted in the 2006 film Walk the Line and his autobiography, this case study of Johnny Cash explores clinically significant events in his childhood and adult life and explores how shame processes may have been implicated in those events and their outcomes. This paper provides
a speculative clinical overview of both life-affirming, protective factors and destructive toxic-shame factors in his life as played out in his drug addiction and eventual recovery.

yrs, 13–14 yrs, and 15–17 yrs. Field measurements of speed, muscular strength, jumping ability, explosive power, and flexibility were made before and after a 6-month training program. The analysis of covariance, using as covariate the initial values, indicated that RG athletes
attained the best scores in speed (p < 0.001), jumping ability (p < 0.001), and sit-ups (p < 0.001) and were more flexible than the control group in the sit-and-reach test (p < 0.01) and shoulder flexibility measurements (p < 0.001). In addition,
gymnasts showed significant progress and obtained the highest scores in the majority of the tests as compared to the control group after 6 months of training. When measuring hip flexibility and leg lifts forward and sideward, gymnasts had better values on the right leg than the left leg. This
observation shows the partial use of the right leg as the prevalent working leg as compared to the left leg which is considered the “support” leg during the performance of different exercises. These results reveal the physical performance characteristics of RG gymnasts as well
as the specific adaptations attained in strength and flexibility after 6 months of training. Coaches and athletes should be aware of these findings in order to develop and maintain physical abilities sufficient for a successful technical performance in RG.

Playing a musical instrument is a constrained motor activity; the instrument has a fixed geometry and playing technique that the performer must accommodate. Although the performer progressively adapts to the instrument during years of education, few options are available for adapting
the instrument to the performer. The present work is intended to quantitatively describe the effects of using different setups of the violin shoulder rest during performance. Three conditions were considered, the maximum and minimum heights allowed by the shoulder rest and the absence of the
shoulder rest. The setups allowed a height variation of <40 mm. Fifteen skilled violin players performed a three-octave scale in G with the three rest setups. An optoelectronic motion capture system measured the positions of passive markers placed on the player's body and on the violin
and bow, in order to compute, by means of mathematical models, the kinematics of the body, violin, and bow. The increase in rest height was significantly related to a reduction in head rotation (–7.0°), left shoulder rotation (–8.5°), and left acromion elevation (–17.2
mm) and to an increase in left shoulder flexion (+8.2°) and left forearm pronation (+8.8°). In general, the results demonstrate that a skilled player is able to adapt to any shoulder rest setup and can maintain the quality of sound, and that the adaptations are primarily those of the
anatomical systems involved in holding the violin and not in holding the bow. Moreover, adjustment of the shoulder rest setup appears to be the individual's search for a tradeoff position, which possibly may be alleviated by adopting objective assessment and innovative shoulder rests.

The violinist's profession involves situations of stress and tension, and bruxism is a clinical phenomenon that is occurring among these musicians with increasing frequency. Materials and Methods: We studied a group of 41 violinists from the region of Murcia in Spain, who completed
clinical questionnaires designed to detect bruxism. The results were compared with those from a random control group who did not play any musical instrument. The SPSS 13.0 software package was used for statistical analysis. Evaluations were done with Pearson's chi-squared test. Results:
In the study group, 73% were diagnosed with bruxism, whereas in the control group, only 34% suffered from this complaint. We found a statistically significant relationship (p<0.05) between violinists and the parafunctional bruxism habit. Conclusions: It could be said that
violin playing can be a factor that predisposes or triggers the appearance of signs and symptoms of bruxism. It is necessary to establish a health education program and preventive measures for professional musicians in order to avoid the development or worsening of bruxism and related problems.
Hearing Loss: A Primer for the Performing Arts
Authors: Owens Douglas T
Published: March 2021

Noise-induced hearing loss (NIHL) is a major health problem that affects an estimated 16.1% of American adults, but for musicians, the onset of noise-induced, or any type of hearing loss, can be a career-changing event. The potential for dangerous sound pressure levels in musical environments
has been documented in numerous studies, with exposures in both short and long durations shown to be harmful. Yet, in theory, NIHL is completely preventable. This review discusses basic information concerning the hearing mechanism and NIHL, audiometry, standards, protective strategies, and
terminology. It aims to provide a general understanding of these processes as they relate to musicians and other performing artists.
A Curriculum on Performing Arts Medicine: Perspectives on Theory and Implementation
Authors: Arjmand Susan
Published: March 2021

The development of professional organizations and clinics dedicated to performing arts medicine and increasing public awareness of the medical problems of performing artists have been evident over the last 25 years, yet there are few formal training programs in performing arts medicine
for healthcare practitioners and no standardized, widely used education tools available for that purpose. This paper proposes a method by which performing arts medicine topics might be introduced to medical practitioners using accepted tools of curriculum design. The goals and objectives of
a proposed curriculum are presented, as well as a needs assessment, educational strategies, assessment methods, implementation and dissemination ideas, and suggestions for curriculum maintenance and renewal. Several features are paramount to successful curriculum change: leadership, cooperative
climate, participation of organization members, evaluation, human resource development, and politics. The role of the team leader is crucial, in that a leader needs to understand the cognitive orientations of both performing arts medicine and primary care as well as of education theory.

There is much evidence to show postural flaws occurring in violin players during performance. The general objective of this study was to observe violinists during performance for the appearance of postural flaws and the frequency with which these flaws occurred. For this work, 20-minute
video recordings were made of four student violinists from an orchestra; the violinists were recorded from a frontal viewpoint, and also anatomic markers were placed on them in order to separately analyze some of the arm and head movements through a computer program. After recording, we captured
images in order to categorize some postures, verifying how often these flaws appeared from different points of view. We conclude that all violinists presented postural flaws which could be avoided because they are not part of the normal instrumental techniques.

Various dance techniques and performances have different effects on the biomechanics of the body and may lead to different injury profiles. Few studies have analyzed the risk of injury associated with particular types of dance, especially in adolescents when accelerated growth compounds
the risk of injury. Ninety-six female dancers with international competitive dance experience from four Balkan European countries were selected from a population of 347 adolescent dancers for this study. Their average age was 13.8 yrs (range, 12 to 16). The subjects were divided into four
groups according to their dance styles: cheerleading, dance show, disco dance, and standard and Latin dance. The first aim of the study was to identify differences between the various dance style groups in body mass index (BMI) and dance sport involvement. According to Wilks' test (oneway
MANOVA), there was a significant multivariate effect (F = 13.8; p < 0.001) between the four dance groups. The dancers belonging to the disco group started systematic training earlier than the other dancers, the standard and Latin dancers practiced the most intensively, and
the show dancers had considerably lower BMI than the disco dancers. The second aim of the study was to define the pain status in 14 body regions for dancers in the various dance styles by monitoring their pain status with the SEFIP questionnaire. The most common locations for pain were the
calves (43.7%), knees (32.7%), and ankles (27.2%). According to the χ2 test, cheerleading dancers reported a significantly higher frequency of knee injuries, and standard and Latin dancers reported a significantly higher frequency of toe injuries. The specific way in which some
dance disciplines are practiced and their dance techniques do induce characteristic injuries.

Control of respiration is important in wind/brass instrument playing. Although respiratory diseases, such as asthma, may affect breathing control, little is known about the prevalence of asthma among wind and brass musicians. The aim of this study was to compare the prevalence of self-reported
asthma between wind/brass musicians and non-wind/brass musicians through different stages of experience. A total of 1960 musicians completed a respiratory health questionnaire. The participants were categorized into the following five subgroups: primary students, secondary students, tertiary
students, community musicians, and professional musicians. Chi-squared and logistic regression analyses were used to compare asthma prevalence and related health outcomes between wind/brass and non-wind/brass musicians. There were no significant differences in current asthma prevalence between
the wind/brass and other musicians in any of the subgroups, apart from tertiary students in whom the prevalence of asthma and related outcomes appeared to be higher among wind/brass musicians. Asthma prevalence among musicians in our survey was similar to that in the overall population. The
results suggest that having asthma does not significantly affect participation in music, the choice of instrument to learn (wind/brass or other), or progression to elite levels as a musician.
A multicriteria model for assessing corporate sustainability in the construction industry

The construction industry is one of the most critical activities for the sustainable development of a country, generating positive and negative economic, social and environmental impacts. These aspects can be measured by Sustainability Indicators and Indices, which are useful tools for society, investors and the government in decision-making, especially when purchasing products and services, as they quantify information about a phenomenon in a given dimension of sustainability. Therefore, the objective of this study is to propose a model for assessing the sustainability of civil construction companies, considering economic, social, environmental and corporate governance criteria. These criteria are aggregated into a single index using the PROMETHEE II multicriteria method, which allows to avoid the compensation effect caused by the aggregation operators based on the additive model. The model was used to evaluate four Brazilian construction companies: Alpha, Beta, Delta and Gamma. The data of these companies were collected in a database of the Brazilian Chamber of the Construction Industry and in the sustainability`s reports published by them. We concluded that the companies Alpha and Gamma, followed by the company Beta presented the best performances in corporate sustainability, while the construction company Delta has the worst level of corporate sustainability.
