Controversial Australian Snakebite Treatment: The Deepest Cut of All
Authors: Singline Paul , Bush Brian
Published: August 2023

Background:

In Australia, until the late 1960s, the emergency first aid treatment for venomous snakebite included cutting to cause bleeding at the bite site in the mistaken belief that it would flush toxins from the wound, thus reducing the patient’s systemic envenoming. However, it failed in this regard and instead caused the patient additional discomfort. Today, again, cutting is used in hospitals during surgical fasciotomies when managing snakebite.

Objective:

The study aimed to report on the rare use of hand and forearm fasciotomies in Australia in October 2021 following snakebite, and highlight the resultant extended morbidity experienced by the patient.

Patient Account:

Common mulga snake (Pseudechis australis) bite has been reported in the Pilbara region, Western Australia. The incident has been reported by a 39-year-old male snakebite victim, with his narrative detailing the events prior to the snakebite until the completion of his outpatient treatment.

Conclusion:

The consensus worldwide is that antivenom is the primary treatment for venomous snakebite and, although a patient may present with symptoms mimicking compartment syndrome, this disease is extremely rare, especially in Australia, where the fangs of endemic snakes are generally too small to penetrate sufficiently deep to cause subcutaneous swelling. The avoidance of surgical intervention in snakebite treatment resulted in much better outcomes for the patient.

Authors: Williamson Grace , Carr Ewan , Fear Nicola T , Dymond Simon , King Kate , Simms Amos , Goodwin Laura , Murphy Dominic , Leightley Daniel
Published: August 2023

BACKGROUND

Alcohol misuse is common in the United Kingdom Armed Forces (UKAF), with prevalence significantly higher than in the general population. To date, digital health initiatives to support alcohol misuse have focused on male individuals, who represent approximately 89% of the UKAF. However, female veterans drink disproportionally more than female members of the public.

OBJECTIVE

This 2-arm participant-blinded (single-blinded) confirmatory randomized controlled trial (RCT) aims to assess the efficacy of a brief alcohol intervention (DrinksRation) in reducing weekly self-reported alcohol consumption between baseline and a 3-month follow-up (day 84) among women who have served in the UKAF.

METHODS

In this 2-arm single-blinded RCT, a smartphone app that includes interactive user-focused features tailored toward the needs of female veterans and designed to enhance participants’ motivations to reduce the amount of alcohol they consume is compared with the UK Chief Medical Officer guidance on alcohol consumption. The trial will be conducted among women who have served at least 1 day of paid service in the UKAF. Recruitment, consent, and data collection will be carried out automatically through the DrinksRation app or the BeAlcoholSmart platform. The primary outcome is change in self-reported weekly alcohol consumption between baseline (day 0) and the 3-month follow-up (day 84) measured using the Timeline Follow Back for alcohol consumption. The secondary outcome is the change in the Alcohol Use Disorders Identification Test score measured at baseline and 3-month follow-up between the control and intervention groups. The process evaluation measures include (1) app use and (2) usability ratings as measured by the mHealth App Usability Questionnaire.

RESULTS

RCT recruitment will begin in January 2024 and last for 5 months. We aim to complete all data collection, including interviews, by May 2024.

CONCLUSIONS

This study will assess whether a smartphone app tailored to the needs of women who have served in the UKAF is efficacious in reducing self-reported alcohol consumption. If successful, the digital therapeutics platform could be used not only to support women who have served in the UKAF but also for other conditions and disorders.

Analysis on the Retirement Model of “Medical Combined with Nursing” for Commercial Insurance Companies to Cope with the Demographic Situation in China
Authors: Zhang Jin
Published: August 2023

China’s population is characterized by an aging problem and a widespread situation where elderly people live with illnesses, which leads to a constant increase in the demand for medical and nursing resources among the elderly. In 2014 September, National Development and Reform Commission jointly with the Ministry of Civil Affairs, the Ministry of Finance and nine other departments jointly issued the “Notice on Accelerating the Promotion of Health and Elderly Services Project Construction”, formally referred to the “medical combined with nursing” expression for the first time. Since then, various industries have been actively exploring the retirement model of “medical combined with nursing”, the insurance industry has also been actively participating in exploring the layout. The retirement model of “medical combined with nursing” can integrate medical and nursing resources to effectively address the reality of China’s demographic situation. In this context, this paper analyzes the participation of China’s commercial insurance companies in the retirement model of “medical combined with nursing” and puts forward optimization suggestions.
PARAMETRIC STUDY OF A CNC TURNING PROCESS USING DISCRIMINANT ANALYSIS
Authors: Sarker Baneswar , Chakraborty Shankar
Published: August 2023

In the present day manufacturing scenario, computer numerical control (CNC) technology has evolved out as a cost effective process to perform repetitive, difficult and unsafe machining tasks while fulfilling the dynamic requirements of high dimensional accuracy and low surface finish. Adoption of CNC technology would help an organization in achieving enhanced productivity, better product quality and higher flexibility. In this paper, an endeavor is put forward to apply discriminant analysis as a multivariate statistical tool to investigate the effects of speed, feed, depth of cut, nose radius and type of the machining environment of a CNC turning center on surface roughness, tool life, cutting force and power consumption. Simultaneous discrimination analysis develops the corresponding discriminant function for each of the responses taking into account all the input parameters together. On the contrary, step-wise discriminant analysis develops the same functions while considering only those significant input parameters influencing the responses. Higher values of hit ratio and cross-validation percentage prove the application of both the discriminant functions as effective prediction tools for achieving enhanced performance of the considered CNC turning operation.
FRACTURE PARAMETERS EVALUATION FOR THE CRACKED NONHOMOGENEOUS ENAMEL BASED ON THE FINITE ELEMENT METHOD AND VIRTUAL CRACK CLOSURE TECHNIQUE
Authors: Cai Yan , Zhou Liming , Li Ming
Published: August 2023

To accurately solve the fracture parameters of enamel, we have established computational nonhomogeneous enamel models and constructed the fracture element of enamel dumb nodes, based on the enamel mineral concentration, nonhomogeneous mechanical properties, and virtual crack closure technique. Through the commercial finite element software ABAQUS and the fracture element of the enamel dumb nodes, we have established the user subroutines UMAT and UEL, which enabled solving of the energy release rates of the nonhomogeneous enamel structure with cracks. The stress intensity factors of central cracks, three-point bend and compact stretched enamels, and double-edge notched stretched enamels are determined. By comparing them with analytical solutions, we have proved that the fracture element of the enamel dumb nodes is highly accurate, simple, and convenient. In addition, the cracks can be other elements rather than singular or special elements; they show versatility and other advantages. The stress intensity factor of the dental enamel can be solved more realistically. Thus, a new numerical method for prevention and treatment of dental diseases is provided.

Fish swarmed Fuzzy Time Series for Photovoltaic’s Forecasting in Microgrid
Authors: Fitri Fitri , Aripriharta Aripriharta , Rahmawati Yuni
Published: August 2023

Forecasting irradiation and temperature is important for designing photovoltaic systems because these two factors have a significant impact on system performance. Irradiation refers to the amount of solar radiation that reaches the earth's surface, and directly affects the amount of energy that can be generated by a photovoltaic system. Therefore, accurate irradiation forecasting is essential for estimating the amount of energy a photovoltaic system can produce, and can assist in determining the appropriate system size, configuration, and orientation to maximize energy output. Temperature also plays an important role in the performance of a photovoltaic system. With increasing temperature, the efficiency of the solar cell decreases, which means that the energy output of the system also decreases. Therefore, accurate temperature forecasts are essential for estimating system energy output, selecting suitable materials, and designing effective cooling systems to prevent overheating. In summary, forecasting irradiation and temperature is important for designing photovoltaic systems as it helps in determining suitable system size, configuration, orientation, material selection, and cooling system, which ultimately results in higher energy output and better system performance. In recent decades, many forecasting models have been built on the idea of fuzzy time series. There are several forecasting models proposed by integrating fuzzy time series with heuristic or evolutionary algorithms such as genetic algorithms, but the results are not satisfactory. To improve forecasting accuracy, a new hybrid forecasting model combines fish swarm optimization algorithm with fuzzy time series. The results of irradiance prediction / forecasting with the smallest error are using the type of Fuzzy Time Series prediction model optimized with FSOA with RMSE is 0.83832.

Authors: Tresna Hilman Fauzi , Pratiwi Daulika , Ariyanti Maya , Fauzi Adryan
Published: August 2023

Neuromarketing utilizes neuroscientific techniques to investigate consumer behavior, providing valuable insights beyond traditional research methods such as questionnaires and interviews
which may not provide a complete understanding of consumer decision-making processes.Electroencephalography (EEG) has emerged as a promising tool for analyzing consumer responses to marketing stimuli. Nevertheless, the neural processing of slogans and their impact on short-term memory recall using EEG signals remains understudied. This research aims to bridge this gap by examining the neural activity associated with the recall of slogans using EEG analysis. By employing a spatial selection and spectral processingmethod, which involves Butterworth BPF filtering and L2-norm normalization to identify optimal channel combinations, active brain areas involved in slogan processing can be identified. Results reveal prominent activation in the frontal and occipital regions, particularly the F4 channel, indicating active recall and visual processing in individuals who correctly respond to slogans. These findings underscore the significance of slogans as visual marketing stimuli and offer insights for effective branding strategies. Leveraging EEG signals and understanding short-term memory processes enables marketers to optimize the impact of slogans on consumer engagement and brand recognition.

Biogeographic affiliation and centers of richness as predictors of elevational range-size patterns for Malesian flora
Authors: Whitman Melissa , Russo Sabrina E.
Published: August 2023

Our goal was to interrogate Janzen’s idea that “mountain passes are
higher in the tropics” by investigating putative ecological and
biogeographic drivers of patterns of elevational range-sizes among
equatorial plant families. We used herbarium records for sixty
species-rich plant families, representing a total of 18535 species, to
estimate distributions over a 4500 m elevational gradient. For each
family, we estimated the change in average range-sizes with increasing
elevation (i.e. Rapoport’s rule, abbreviated as ERR) and quantified 15
metrics of familial richness distribution, evolutionary age, and
biogeographic affiliation. We visualized covariation across families
using used phylogenetic principal components analysis (pPCA), with color
illustrating endemism. We then evaluated how family-level ERR slopes
correlated with each metric individually, and the first two pPCA
components, using phylogenetic independent contrasts. Families with
greater Sundaland endemism, or richness that was restricted to tropical
lowland forests, had positive ERR slopes. Families with stronger Sahul
affiliation, or montane centered richness, had shallower, neutral, or
negative ERR slopes. Families with Wallacea affiliation, broader
latitudinal or elevational distributions, cosmopolitanism, or older
evolutionary age had mixed results. Our findings support Janzen’s
hypothesis that “mountain passes are higher in the tropics.” If long
term climate stability over millions of years promotes habitat
specialization, then among taxa with long-term tropical affiliations, we
would expect smaller range-sizes within lowland forests, with range-size
expansion towards higher elevations, expressed as a positive ERR slope.
Conversely, variation in growing conditions should promote larger,
relatively consistent, range-sizes expressed as a neutral ERR slope. Our
results support this corollary because of the dichotomy of ERR slopes
observed in relation to elevational and historical biogeographic
positioning, which may be an indicator of vulnerability of these plant
groups to contemporary climate change.
Annual degradation rates and soiling losses of photovoltaic systems composed of recent crystalline silicon technologies in Japan
Authors: Ishii Tetsuyuki
Published: August 2023

The purpose of this study is to investigate the annual degradation rates
of photovoltaic (PV) systems composed of PV modules based on recent
crystalline silicon (c-Si) PV technologies. We investigated the annual
degradation rates of four PV systems composed of different c-Si PV
technologies. Furthermore, the effects of soiling on the annual
degradation rates of these PV systems were examined. The results
obtained indicate that the apparent annual degradation rates of the PV
strings before surface cleaning were 0.8, 1.6, 1.4, and 1.2%/year,
respectively, because of optical losses due to dust particles, although
the surfaces of the PV arrays had been washed by plentiful rainfall
under subtropical climatic conditions. However, the inherent annual
degradation rates of the PV strings after surface cleaning were 0.1,
0.6, 0.0, and 0.3%/year, respectively. These low degradation rates
indicate that the PV systems composed of the recent c-Si PV technologies
all offered quite stable performance.

Authors: Schafer Robyn , Bovbjerg Marit , Cheyney Melissa , Phillippi Julia C.
Published: August 2023

Objective Investigate maternal and neonatal outcomes associated
with breech presentation in planned community births in the United
States Design Cohort analysis of a national perinatal data
registry Setting Homes and birth centres, United States
Sample Medical records of individuals with a term, singleton
gestation (N=71,943) planning community birth at labour onset
Methods Descriptive statistics to calculate associations
between types of breech presentation and perinatal outcomes Main
Outcome MeasuresMaternal: intrapartum/postpartum transfer,
hospitalization, caesarean, haemorrhage, severe perineal laceration,
duration of labour stages and membrane rupture Neonatal:
transfer, hospitalization, NICU admission, congenital anomalies,
umbilical cord prolapse, birth injury, intrapartum/neonatal death
Results One percent (n=695) of individuals experienced breech
birth, with most (57%) presenting frank breech (19% complete, 18%
incomplete, 5% unknown breech type). Among all breech labours, there
were high rates of intrapartum transfer and caesarean (OR 9.0, 95% CI
7.7-10.4 and OR 18.6, 95% CI 15.9-21.7, respectively), with no
substantive difference based on parity, planned site of birth, or level
of health system integration. Risk of nearly all assessed neonatal
outcomes was higher for all breech presentation types, including
hospital transfer, NICU admission, birth injury, and umbilical cord
prolapse. Breech presentation was also associated with increased risk of
intrapartum/neonatal death (OR 8.5, 95% CI 4.4-16.3), even after
excluding congenital anomalies. Conclusions All types of breech
presentation in community birth settings are associated with increased
risk of adverse neonatal outcomes. Findings contribute to informed
decision-making and reinforce the need for accessible, high-quality care
for planned vaginal breech birth in hospitals.
The Epidemiology of Acute Respiratory Distress Among Children Referred to the Emergency Department of a Tertiary Children's Hospital, A Cross-Sectional Study from Iran
Authors: Bayat Mahdis , Shojaeian Fatemeh , Sayyah Samira
Published: August 2023

Background and Aim: Respiratory distress is one of the most
common underlying causes of Emergency Department visits in children,
with a high morbidity and mortality rate which could raise a lot of
concerns, acquiring early recognition of the underlying cause and
appropriate treatment. The current study aimed to determine the
prevalence and distribution of underlying causes of respiratory
distress. Material and Methods: In this retrospective cohort
study, demographic and clinical information of 154 patients older than
one month who were referred to the Mofid Children’s Hospital emergency
department in Tehran, Iran, from October 2018 to April 2019 were
gathered from Hospital Information System (HIS) and analyzed with SPSS
Statistics 23.0 version. Results: 154 participants were
recruited with a mean age of 33.02±37.21 months, and 66% were male. The
most common clinical symptom among these children was tachypnea
(90.6%). Asthma (35.1%), pneumonia (31.8%), sepsis (8.4%),
bronchiolitis and croup (7.8%), and foreign body (7.1%) were the most
common causes of respiratory distress. When comparing clinical symptoms,
nasal flaring was substantially more common in younger individuals than
in older patients (P-value=0.04), but there were no significant
differences between the sexes. In terms of underlying causes, patients
with bronchiolitis and airway malformation were considerably younger
than those without these disorders (P-value 0.001), whereas patients
with chest wall deformity were more likely to be older (P-value=0.01),
and it was more frequent among girls (P-value=0.03).
Conclusion: Respiratory distress can be manifested with a
variety of signs and symptoms and different underlying causes which may
defer in different genders, ages, and regions. Among patients referred
to a tertiary center in Tehran, tachypnea was the most common clinical
symptom, and asthma was the most frequent cause of respiratory distress.
Knowing the underlying causes of this emergent clinical status in
pediatrics can help us in developing appropriate treatment approach.
Species-specific stoichiometric effects of leaf litter on algal growth, production, and cell quotas
Authors: Ho Pei-Chi , Nakajima Suzuna , Urabe Jotaro
Published: August 2023

Dissolved organic matter and nutrients released from forest leaf litter
are important cross-ecosystem resources that support freshwater
ecosystems. Dissolved organic matter released from leaf litter is one of
the allochthonous sources for heterotrophic organisms in freshwater
communities. However, the role of macro- and micronutrients released
from leaf litter in producing autochthonous organic matter in aquatic
ecosystems is not necessarily well understood. In this study, therefore,
we investigated how dissolved nutrients released from leaf litter affect
the algal growth, biomass production, and cell elemental quotas.
Specifically, we focused on the responses of the green algae to TDN,
TDP, and micronutrients released from the leaf litter of 11 temperate
tree species. We found that the algal growth rate increased with TDP
when micronutrients were amended. In contrast, the algal biomass
production increased with TDN, regardless of micronutrient amendment.
Micronutrient limitation of algal growth rate was found in the leaf
litter leachates from oak, Japanese elm, and Japanese hemlock. However,
algal biomass production was limited by micronutrients only in the leaf
litter leachate from Japanese hemlock. More importantly, leaf litter
leachates from different tree species altered algal cell quotas and
C:N:P ratios, which would affect secondary production. These results
suggest that forest vegetation change or succession affect the quantity
and quality of autochthonous organic matter and thus the mass transfer
efficiency in the aquatic community by changing the stoichiometry of
nutrient input from the leaf litter.
Role of cell wall polysaccharides in water distribution during seed imbibition of Hymenaea courbaril L.
Authors: Buckeridge Marcos S. , Grandis Adriana , Santos Henrique , Tonini Patrícia P. , Salles Ivan S. , Peres André Salles Cunha , Carpita Nicholas C.
Published: August 2023

Seed water imbibition is critical to the seedling establishment in
tropical forests. The neotropical tree Hymenaea ( Hymenaea
courbaril) is a model system to study seed storage xyloglucan (XyG)
mobilization after germination. Typical of many legumes, seed coats of
Hymenaea are formed by a palisade of lignified cells, conferring
imperviousness to water and the need for scarification to germinate.
Below this fortified cell layer, a parenchyma layer, composed mainly of
pectins, is juxtaposed on the surface of the cotyledon, whose cells
contain thick cell walls containing mostly XyG. Here we used scanning
electron and fluorescence microscopies, and NMRi spectroscopy to
visualize water uptake and distribution in seeds of Hymenaea. An
experiment with in vitro Hymenaea pectin or XyG composites with
cellulose from the Whatman paper demonstrated the cell wall polymers’
functions during imbibition. We observed that water follows distinct
pathways containing different cell wall compositions to varying speeds
through the seed coat and cotyledons until embryo metabolism is
activated synchronically with storage mobilization. We conclude that the
dynamic interactions between water and wall polysaccharides (pectins and
hemicellulose) of different seed tissues are central to determining
water distribution and preparing the seedling for establishment.

are obtained under some suitable conditions. In order to assess the finite
sample performance, we also present a numerical simulation in the last

Some geometric and physical properties of pseudo m*-projective symmetric manifolds
Authors: Hazra Dipankar , De Chand , Shenawy Sameh , Syied Abdallah Abdelhameed
Published: August 2023

In this study we introduce a new tensor in a semi-Riemannian manifold, named
the M*-projective curvature tensor which generalizes the m-projective
curvature tensor. We start by deducing some fundamental geometric properties
of the M*-projective curvature tensor. After that, we study pseudo
M*-projective symmetric manifolds (PM?S)n. A non-trivial example has been
used to show the existence of such a manifold. We introduce a series of
interesting conclusions. We establish, among other things, that if the
scalar curvature ? is non-zero, the associated 1-form is closed for a
(PM?S)n with divM* = 0. We also deal with pseudo M*-projective symmetric
spacetimes, M*-projectively flat perfect fluid spacetimes, and
M*-projectively flat viscous fluid spacetimes. As a result, we establish
some significant theorems.

The semi-T3-separation axiom of Khalimsky topological spaces
Authors: Han Sang-Eon , Özçağ Selma
Published: August 2023

The paper initially studies both the s-T3-separation and the
semi-T3-separation axiom of Khalimsky (K-for brevity) topological spaces.
To do this work, first we investigate some properties of semi-open and
semi-closed sets with respect to the operations of union or intersection and
further, a homeomorphism, and a semi-homeomorphism. Next, we study various
properties of semi-topological properties of K-topological spaces such as
simple K-paths. Finally, after introducing the notion of a
semi-T3-separation axiom which is broader than the s-T3-separation axiom, we
find a sufficient and necessary condition for a Khalimsky topological space
to satisfy the semi-T3-separation axiom.

Authors: Nita Sari  , Widiastuti Endang Linirin , Pratami Gina Dania , Tugiyono Tugiyono
Published: August 2023

The amount of garbage that accumulates in the waters causes environmental damage which is getting worse. The breakdown of plastic waste into smaller particles that have been degraded is called microplastic. This study aims to analyze the number of particles, shapes, and types of microplastic polymers found in the water and sediments of Mahitam Island. The research location was determined by purposive random sampling with three stations based on plastic sources, namely Station I, Station II, and Station III, which had different characteristics from laboratory-based testing for seawater and sediment. Microplastic analysis on seawater samples was carried out by adding a solution of 70% ethanol, 30% H2O2, and 30% NaCl, and on sediment samples was carried out by adding a solution of FeSO4 (0.05 M), NaCl, and 30% H2O2. The content of the number of particles and the shape of microplastics were analyzed using a microscope, while the analysis of microplastic polymers using FT-IR. The first thing to do is to extract microplastics The forms of microplastic found are Fiber, Film, Fragments, and Pellets. The highest number of microplastic particles was the type of film for water samples at Station 1 and Station 2 for sediment samples. The types of polymers found in water and sediments on Mahitam Island are polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), and polystyrene (PS) which come from plastic waste. Microplastics are known to originate from the use of plastic originating from tourist activities and originating from the sea currents of Mahitam Island.

HenHen Collection merupakan toko pakaian yang menjual berbagai macam jenis pakaian. Toko tersebut saat ini mengalami kesulitan dalam memilih supplier pakaian dikarenakan banyaknya kriteria yang dipertimbangkan dan proses pemilihan supplier masih berdasarkan perasaan dan perkiraan pemilik toko. Situasi semacam ini dapat berdampak pada ketersediaan barang yang akhirnya berpengaruh terhadap keuntungan, kepuasan, dan kesetiaan pelanggan. Kesulitan tersebut dapat dipecahkan dengan membangun sistem pendukung keputusan untuk memilih supplier pakaian. Penilaian pemasok yang sebelumnya cenderung bersifat subjektif dapat dipecahkan dengan menerapkan metode Simple Additive Weighting (SAW) yang diimplementasikan ke dalam aplikasi berbasis website. Metode ini dapat mencari alternatif optimal berdasarkan kriteria yang telah ditentukan dengan melakukan penjumlahan terbobot untuk semua atribut pada setiap alternatif yang ada. Dengan metode tersebut, maka diharapkan dapat membandingkan setiap alternatif supplier secara seimbang dan menghasilkan alternatif melalui perhitungan yang pasti dan konsisten.

This study examined the effect of the family business on firm performance and whether the political connection moderates these relationships. Final sample consisted of 1,969 firm-year observations from 2013 - 2017. Family characteristics and political connections data were hand-collected from annual report and financial data were extracted from Eikon Datastream. We found that family chairmanship and high family ownership concentration can destroy firm performance, exhibited by low Tobin Q. However, the moderating effect of political connection between family business and firm performance showed a positive and significant association. This implies that politicians in the family firm can create firm performance as they can work as external watchdogs. Additional analysis showed that political connections in high family ownership can destroy firm performance. These findings provide practical implications for regulators and investors that they should be mindful of the designation of family members and appointment of politicians in firms as it may create agency costs and destroy firm performance. This study adds to the limited, albeit important evidence on the joint effect of politically connected firms and family businesses on firm performance. Keywords: family business, political connection, firm performance
"[Co]existence as Intersensoriality in the Symphonies of Havasi Balázs "

"We often wonder about piano music. And we're not just wondering because it fascinates us, but because it forces us to ask questions about life and the hidden senses of the sounds. For several times the music fills our lives. But how does it fill it? Many times a poem written by William Sharp or by Michael Shewmaker is a question for me as a philosopher. Furthermore, a composed song for piano by Havasi Balázs, makes us think a lot about a poem, or about anything which fascinates our mind. But despite the mind, there are many perceptions which work together to have a right judgement on the perception of the music. If we want to find how the music fulfills our lives with significances, we have to bring a phenomenological method in understanding these meanings. The phenomenology has an unique answer, because it finds out to answer to how the things (these phenomenological objects) are becoming. In this article we will show how the compositions of Havasi Balázs are up to date through the aesthetic sphere of the phenomenology and how they are entities in the phenomenological field of perception nowadays. For these reasons, it seemed essential to us to offer a phenomenological perspective to the symphonies realised by Havasi Balázs. Keywords: Havasi Balázs, piano, contemporary classic music, phenomenology of sound, perception, conscience."

"Outstanding representative of the classical music composed in the transition period from XVIIIth to XIXth centuries, Ludwig van Beethoven remains memorable in the history of music through the strength, audacity, and remarkable rhetoric of his musical discourse. With the mastery of a demiurge, he coalesces in the texture of his thematic ideas’ heroic, pathetic or pastoral configurations, making the most of the technical-expressive possibilities of the epoch’s instruments into a authentic instrumental-interpretative manner. Advocate of a prevailingly monumental interpretation, Beethoven will perfect his instrumental style through authentic details which are the subject of the varied attack modes, of ornamentation, articulation, pedaling, etc., which are the personalized elements of a challenging technique. Approaching the aspect of Beethoven’s ornamentation, the present article will bring into focus the identification of the dominant ornamental components and their treatment from an interpretative viewpoint with emphasis on the authenticity of the artistic representation. Keywords: Art & Music, piano, Beethoven’s language, ornamentation, interpretation, authenticity"
