Septic state in the differential diagnosis of fever of unknown origin
Authors: Ilić Luka , Jeremić Aleksandar
Published: April 2024

Introduction: In the modern world, fever of unknown origin is becoming an increasingly common entity with varied etiologies. Septic condition has a significant role as an etiological factor of fever of unknown origin, often being overlooked or treated late. Objective: To determine the frequency of sepsis, to establish demographic characteristics, clinical presentation of the disease, to identify the proportion of proven pathogens and their distribution by type, and to present laboratory analyses of patients diagnosed with sepsis upon admission and discharge from the hospital. Materials and Methods: The study included patients treated at the Clinic for Infectious and Tropical Diseases of the Clinical Center of Serbia, in the Department of Clinical Pharmacotherapy, from December 1, 2014, to December 31, 2017, with documented sepsis during the investigation of the etiology of FUO. Results: Among 420 patients studied, sepsis was documented in 50 (11.9%). The study included 29 (58%) women and 21 (42%) men, with an average age of 63.76 ± 13.6 (24-90) years. The causative agent of the disease was detected in blood cultures in 40 (80%) patients, while not in 10 (20%). Elevated body temperature occurred in 49 (98%) patients, whilst 24 (47%) experienced chills and shivering, 13 (25.5%) nausea, and 16 (31.4%) vomiting. Headache occurred in 8 (16%) patients, while diarrhea, urinary symptoms, and altered consciousness were observed in 11 (21.6%) patients. By comparing the median values of biochemical analyses of patients obtained upon admission and discharge from the hospital, a statistically significant difference (p<0,01) was found, indicating a decrease in laboratory parameter values such as erythrocyte sedimentation rate, C-reactive protein, total leukocyte count, and percentage of segmented leukocytes. Conclusion: In the observed sample, sepsis occurs relatively frequently (11.9%) as an etiological factor of FUO. In the differential diagnosis of fever of unknown origin, despite significant progress and development of sophisticated diagnostic procedures, one should always consider potential systemic infection as a possible cause, among which septic condition occupies an important place, even when initial examinations do not lead to such a conclusion.
Perioperative management of high-risk cardiovascular patients in abdominal surgery
Authors: Anđelković Ana , Tanasić Stefan
Published: April 2024

Introduction: The preparation of cardiovascular patients for different types of surgical interventions represents a challenge in an anesthesiologist's everyday practice. Its complexity depends on the severity of the underlying disease, the effects of the drug treatment, urgency, and the type of surgical intervention. Different types of scoring systems are available when it comes to the assessment of cardiovascular risk in patients during surgery. One of them, Revised Cardiac Risk Index (RCRI/Lee criteria), stands out due to its comprehensiveness and simplicity, and is thus applied most frequently. Using the example of two patients with cardiovascular disease, the aim of this paper is to show how the risk of perioperative complications can be reduced by applying a multidisciplinary approach, along with an individualized strategy and modern guidelines. Case reports: In the first case, we presented a patient with acute appendicitis. Because of angina pectoris, one month prior to the planned abdominal surgery, Percutaneous Coronary Intervention was performed placing one stent, after which dual antiplatelet drugs were prescribed. A patient with acute cholecystitis is presented in the second case. Coronary artery bypass grafting is planned within a month upon the abdominal surgery, due to a severe form of ischemic cardiomyopathy. Both patients are at high risk of myocardial damage during surgery, the first patient being at high risk of hemorrhage as well. Conclusion: The appropriate balance in the perioperative care of such patients can be achieved by a multidisciplinary approach, as well as by adapting modern guidelines to patients' individual needs.

Aim: The study aimed to identify factors associated with pro-integration attitudes to the European Union (EU) among Serbian medical freshmen to promote integration. Methods: In the period from 2010 to 2021, within the scope of the distance learning module "Medicine & Society", a total of 1333 freshmen of the Faculty of Medicine of the University of Belgrade (1333/1940, i.e., response rate 68.7%) has responded to the semi-structured questionnaire inquiring their perception of the EU integration advantages and disadvantages. The association of the pro-EU attitude (vs cons-EU / undecided) with perceived advantages and disadvantages was presented using the odds ratio (OR) and 95% confidence interval (CI). Results: A total of 48.5% of respondents were pro-EU integration, 42.7% were undecided and 8.9% were cons-EU (i.e., 585, 525, and 107, respectively) integration of Serbia. The pro-EU attitude was 55% more likely among male respondents (OR: 1.55, 95% CI:1.14-2.10), among respondents who were able to identify advantages of EU integration such as easier mobility (OR: 2.87, 95% CI: 1.80-4.57), variety of job opportunities (OR: 2.06, 95% CI: 1.45-2.93), and among those for whom competition at the EU healthcare market is not a disadvantage of the EU-integration (OR: 8.56, 95% CI: 1.79-40.92). The pro-EU attitude was less likely among respondents who identified high emigration of medical doctors as a disadvantage of the EU integration, by 45% (OR: 0.55, 95% CI: 0.36-0.84). Conclusion: During the last decade, the share of Serbian medical freshmen with pro-EU and undecided attitudes suggests the need for a stronger international initiative of EU and national actors. Advantages such as easier mobility, competition in the EU healthcare market, and a variety of employment opportunities promote an integrationist attitude, in contrast to the large emigration of medical doctors.

últimos de UCD: el Grupo Parlamentario Centrista tras la desaparición de Unión de Centro Democrático, 1982-1986
Authors: Magaldi Fernández Adrián
Published: April 2024

Las elecciones de 1982 supusieron un rotundo fracaso para el hasta entonces partido gubernamental, Unión de Centro Democrático, lo que muy pronto supuso la disolución de dicha formación. A pesar de ello, los escasos diputados centristas constituyeron un grupo parlamentario que se mantuvo unido hasta las siguientes elecciones, celebradas cuatro años después. El objetivo de este artículo es analizar los perfiles y actuación de sus integrantes para revelar cómo, a pesar de las dificultades, consiguieron mantener una línea de actuación independiente situada en el centro del espectro político.
España, una democracia militante
Authors: Fernández Casadevante Pablo
Published: April 2024

¿Hasta dónde pueden llegar las democracias en la defensa de sus sistemas? Descartada la vigencia del relativismo democrático liberal, más controversia hay respecto del carácter más o menos militante de los distintos ordenamientos jurídicos europeos. De hecho, su reconocimiento en España es objeto de rechazo por el Tribunal Constitucional, esgrimiendo para ello la inexistencia de cláusulas expresas de intangibilidad, lo que a su vez impediría el control ideológico de los partidos al margen del Código Penal.El presente trabajo sirve para constatar lo erróneo del enfoque, con un sentido originario del término, y una práctica estatal y supranacional que avalan el carácter multiforme del concepto de democracia militante y su igual proyección sobre el ordenamiento jurídico español.
Big Data: riesgos y soluciones desde el Derecho y desde los principios
Authors: Martín Jiménez Francisco Javier
Published: April 2024

El avance de algunas tecnologías, especialmente las relacionadas con la comunicación (redes sociales) y la utilización generalizada de dispositivos electrónicos capaces de transmitir información, algunos de ellos sin intervención de las personas, ha generado ingentes cantidades de datos que, si son tratados, pueden socavar derechos fundamentales y sus garantías reconocidas en nuestro entorno europeo. Este hecho no ha pasado desapercibido y genera una gran preocupación en la medida en que estos tratamientos masivos de datos no tienen un adecuado marco jurídico que responda a los nuevos riesgos que conllevan. Desde el Derecho, en sentido amplio, sin excluir las recomendaciones de los órganos administrativos supervisores, desde los principios éticos y desde el peculiar manejo de los datos personales, se están aportando diferentes soluciones. El análisis de riesgos y sus posibles soluciones marcan la línea de este trabajo.
Asistencia militar y militarización: una aproximación distintiva frente al restablecimiento del orden constitucional en el marco del legítimo derecho a la protesta social
Authors: Coll Alex Rodrigo
Published: April 2024

El presente artículo aborda la noción de protesta social como una institución con alcance bidimensional; como derecho fundamental y como mecanismo de participación, ejercido de forma preferente, por los grupos que conviven en desventajas frente a los demás agregados sociales. También explica los alcances que, como medios de intervención, poseen las nociones de asistencia militar y militarización del territorio en el marco de la protesta social. Explica las distancias aplicativas y conceptuales que existen entre las funciones de seguridad y de defensa en el marco del Estado Constitucional de Derecho, asignadas a dos componentes distintos de la Fuerza Pública, el policial y el militar, respectivamente. Para ello se recurre al método jurídico-constitucional en el que los derechos fundamentales obran como medios de alcance teórico-conceptual, que nutren de contenidos sustanciales al derecho vigente para su consecuente aplicación y para su material realización, tomando como referente general el contexto latinoamericano desde una aproximación descriptiva específica del caso colombiano en el Paro nacional 2021. Finaliza sosteniendo que, en la protesta social, la acción colectiva no solo es controladora de la acción estatal, sino también prescriptiva del ordenamiento normativo con incidencia en su permanente transformación.
Enforcement of the Digital Markets Act

Published: April 2024

Since March 2024, the undertakings Alphabet/Google, Amazon, Apple, Byte-Dance/TikTok, Meta, and Microsoft must comply with the obligations of the Digital Markets Act (DMA). Within the first month after the 6-months implementation period has ended, the European Commission opened investigations against Alphabet/Google, Apple, and Meta for non-compliance with the obligations in the DMA. All proceedings can be traced back to related competition law cases. However, only two proceedings follow the same reasoning as their competition law role models, while the case against Meta reveals that the approaches under the DMA can and will deviate significantly to those under competition law and data protection law.

Authors: Ramírez Pacheco Diana Laura
Published: April 2024

En todo momento, las personas y sus comunidades deben ser el porqué y el para qué de los proyectos de cooperación internacional para el desarrollo (CID). Velar por su bienestar a través de su empoderamiento y de la ampliación de lo que realmente son capaces de ser y hacer en sus vidas constituye la base para asegurar que las intervenciones de desarrollo sean endógenas, genuinas y sostenibles en quienes buscan favorecer. Para ello, el enfoque de capacidades se presenta como un marco analítico para valorar las transformaciones en la vida de las personas participantes, las libertades que han alcanzado y cómo se ha incrementado su sentido de agencia a partir de su involucramiento en un proyecto de CID. Este manual tiene el propósito de mostrar una aproximación de la aplicación empírica de este enfoque en un proyecto concreto de cooperación técnica internacional, estando dirigido a estudiantes de ciencias sociales, profesionales de la cooperación internacional y el desarrollo, así como a personas funcionarias públicas y de organizaciones de la sociedad civil que busquen valorar de manera más amplia el alcance de los proyectos de CID, incluso más allá de los resultados esperados. Lo anterior puede contribuir a mejorar la calidad de las intervenciones en función de lo que las personas participantes encuentren necesario y valioso para sus vidas.

Harmonizing Compliance: Coordinating Automated Verification Processes within Cloud-based AI/ML Workflows
Authors: Akter Sohana
Published: April 2024

The significance of ensuring security and upholding data privacy within cloud-based workflows is widely recognized in research domains. This importance is particularly evident in contexts such as safeguarding patients' private data managed within cloud-deployed workflows, where maintaining confidentiality is paramount, alongside ensuring secure communication among involved stakeholders. In response to these imperatives, our paper presents an architecture and formal model designed to enforce security measures within cloud workflow orchestration. Central to our proposed architecture is the emphasis on continuous monitoring of cloud resources, workflow tasks, and data streams to detect and preempt anomalies in workflow orchestration processes. To accomplish this, we advocate for a multi-modal approach that integrates deep learning, one-class classification, and clustering techniques. In essence, our proposed architecture offers a comprehensive solution for enforcing security within cloud workflow orchestration, harnessing advanced methodologies like deep learning for anomaly detection and prediction. This approach is particularly pertinent in critical sectors such as healthcare, especially during unprecedented events like the COVID-19 pandemic.
Ensuring Compliance Integrity in AI ML Cloud Environments: The Role of Data Guardianship
Authors: Rana Sohel
Published: April 2024

Artificial intelligence (AI) has become ubiquitous across various industries, including security, healthcare, finance, and national defense. However, alongside its transformative potential, there has been a concerning rise in malicious exploitation of AI capabilities. Simultaneously, the rapid advancement of cloud computing technology has led to the emergence of cloud-based AI systems. Unfortunately, vulnerabilities inherent in cloud infrastructure also pose security risks to AI services. We recognize the critical role of maintaining the integrity of training data, as any compromise therein directly impacts the effectiveness of AI systems. In response to this challenge, we emphasize the paramount importance of preserving data integrity within AI systems. To address this need, we propose a data integrity architecture guided by the National Institute of Standards and Technology (NIST) cybersecurity framework. Leveraging blockchain technology and smart contracts presents a suitable solution for addressing integrity challenges, given their features of shared and decentralized ledgers. Smart contracts enable automated policy enforcement, facilitate continuous monitoring of data integrity, and help mitigate the risk of data tampering.

Published: April 2024

Neste artigo, destaca-se o desenvolvimento histórico e epistemológico dos métodos para determinar a equação de uma cônica específica, desde Menêcmo com a Oxytome até as contribuições de Apolônio com a Elipse. O texto revela um movimento sequencial histórico, utilizando a História da Matemática para enriquecer o ensino da cônica que conhecemos como Elipse, explorando métodos diversos para determinar sua equação, culminando na expressão reduzida. Isso é feito a partir de uma pesquisa bibliográfica em fontes primárias, secundárias e terciárias. Embora não se concentre nas potencialidades das tecnologias digitais, destaca-se o papel do GeoGebra na realização precisa de figuras e na compreensão de correlações geométricas e algébricas durante a investigação histórica. Consideramos que este tipo de investigação histórica é de importância conceitual para os professores e de importância didática para o desenvolvimento, apropriação e representação histórica não apenas dessa cônica, mas também de outras curvas, no âmbito científico e disciplinar da matemática e no seu ensino.

Tässä artikkelissa syvennymme oppikoulujen yläluokkalaisten etujärjestö Suomen Teiniliiton (1939–83) historiakuvan rakentumiseen sekä muistamisen tapoihin. Tarkastelemme, millaiset entiset teiniliittotoimijat ovat ottaneet ja saaneet tilaa muistella ja vaikuttaa järjestönsä historiakuvan rakentumiseen ja arvioimme, miksi tietyt teemat ovat korostuneempia kuin toiset. Keskitymme erityisesti kahteen teemaan, teinitoiminnan 1970-luvun puoluepoliittiseen vaiheeseen sekä sukupuolen merkitykseen keskittyvään muisteluun. Teiniliiton historiakuva on rakentunut vuosikymmenten kuluessa, järjestön toiminnan alusta saakka. Eri teinisukupolvet ovat osallistuneet prosessiin aktiivisesti, mutta teinitoiminnan pitkä kaari kulminoituu useimmiten puoluepolitisoitumisen ja miespuolisten teiniaktiivien käymien valtakamppailujen kauteen. Historiakuvan voimakas keskittyminen yhteen ajanjaksoon on jättänyt varjoonsa Teiniliiton muita merkittäviä vaiheita ja saavutuksia, kuten työn kouludemokratian, peruskoulu-uudistukseen ja kansainvälisyyden edistämisessä sekä tyttöjen nousun aktiivisiksi yhteiskunnallisiksi toimijoiksi.

Assessment of Halon-Free Agents for Fire Safety Application in Aircraft Propulsion System
Authors: Dinesh Akhil , Diakostefanis Michael , Sampath Suresh
Published: April 2024

Halon 1301 is an effective total flooding fire suppression agent which is widely employed in aircraft cargo and propulsion systems for emergency fire scenarios. The production of Halon 1301 was banned by the Montreal Protocol in 1994 due to its environmental impact on ozone depletion and long atmospheric lifetime. Thus, a credible alternative is required for fire safety application on-board aircrafts. This study forms a follow-up to the work published by A. Dinesh et.al and M. Diakostefanis et.al which studied halon-free fire suppression in aircraft cargo bay through CFD and experimental validation respectively. Due to constraints in cost and logistics of testing fire suppression in a gas turbine engine, a computer modelled fire zone of a hypothetical high-bypass turbofan engine was used to simulate and evaluate the fire suppression performance of three Halon-free agents - HFC-125, HFC-227ea and FIC-13I1. Halon 1301 was also simulated to provide baseline comparison to the alternative agents. The capacity to inert was based on the distribution of agent concentrations subjected to a heptane-based fuel fire. Simulations were conducted at ISASLS and 40,000 feet to represent the engine’s operating environment. Overall, it was found that HFC-125 and HFC-227ea satisfactorily suppressed fire at both ambient scenarios. It was found that agent density and suppression concentration significantly influenced the agent’s ability to mix with ambient air and flood the fire zone. Density of the agent combined with higher inertion concentrations also influenced formation of localised recirculation zones which influenced mixture distribution in the fire zone. The simulations enabled identification of individual changes to agent flow characteristics at different operating conditions and demonstrated the performance criteria of Halon 1301 along with the proposed alternative agents for successful fire suppression. Through this study, it was found that all the agents except FIC-13I1 passed the minimum suppression criteria making HFC-125 and HFC-227ea suitable agents for replacement of Halon 1301. The minimum concentration and simulation design in the engine fire zone were validated against the experimental tests conducted by NIST in Boeing 777’s dual-spool high bypass turbofan engine for Halon 1301 and HFC-125. The failure of FIC-13I1 was attributed to the complex design in fire zone and could be overcome by considering a higher factor of safety for this design and injecting higher mass flow rate of the agent into the fire zone. The outcome of this study proposes further work to be carried out through experimental validation of the CFD simulations which will be key to progress the technology to higher TRL and meet aviation certification requirements. Further work may also explore blended agent configurations to tailor the agent characteristics to meet suppression requirements for maintaining safety and reliability of the system.

ENHANCING POWER QUALITY IN DC SYSTEMS WITH UPFC-BASED MULTILEVEL CASCADE CONVERTER
Authors: Rajesh V. , Srinivas Dr. D. , Rao P. Srinivasa , Swathi Ganji
Published: April 2024

Mixture Although renewable energy is a good substitute for conventional energy, connecting it to the grid can provide new difficulties. Similarly, for wind turbines to keep the grid stable and reliable, they need to provide high-quality electricity. To reduce the harmful environmental effects of conventional energy generation, more wind turbines are being connected to the electrical grid. Understanding how disturbances impact the quality of the energy is important in order to connect a wind turbine to the grid. The voltage and frequency must be as stable as feasible. This stability may be obtained using FACTS devices. Inverters that are either voltage-source or current-source have been used recently to reduce oscillation in the power supply. Moreover, several of them are used to improve the transient and dynamic stability of wind power generating systems (WPGS). When a wind turbine is linked to the grid, it produces electrical switching behaviour, voltage sag and swell, flashing and harmonic emissions, and active and reactive energy. A three-phase grid-linked wind-driven induction generator's reactive power need may be adjusted in a number of methods, such as by applying instantaneous pq theory and UPQC to adjust for harmonics produced by a non-linear load connected to the PCC. MATLAB/SIMULINK is used to simulate the FACTS Device UPQC control mechanism in order to improve power quality.

A NOVEL SECURE OUTSOURCING METHOD FOR MEDICAL DATA
Authors: REDDY Dr. P. Vijay Paul , Ramesh Dr V. , BABU Dr. B.V , LAKSHMI Donthireddy Vijaya
Published: April 2024

Medical imaging is essential for diagnosing illnesses, and due to the delicate nature of medical images, stringent security and privacy measures must be in place. Medical images should be secured before being outsourced in a cloud-based medical system for Healthcare Industry 4.0. However, it is difficult and currently impractical to process queries over encrypted data without first performing the decryption step. In the paper, we suggest an effective method for locating the precise nearest neighbour in a set of encrypted medical photos. By obtaining the lower bound of the Euclidean distance, which is correlated with the mean and standard deviation of the data, we can eliminate candidates instead of computing the Euclidean distance. Our method can find the precise nearest neighbour as opposed to an approximation, unlike the majority of other existing approaches. We then assess our suggested strategy to show its usefulness.
ENHANCING DATA SECURITY: SECURE AND EXPRESSIVE ACCESS CONTROL FOR CLOUD STORAGE
Authors: Prasad A. Hanumanth , Ramanaiah G. , Chakravarthy M. Ayyappa , Ramanaiah Pillutla Venkata
Published: April 2024

In order to ensure the classification of reappropriated information while also providing adaptable information access to cloud clients whose information is not under their physical control, secure distributed storage is a growing cloud administration trend. One of the most promising methods for verifying the administration's certification is cypher text-policy attribute-based encryption (CP-ABE). Due to the inherent "win big or bust" unscrambling feature of CP-ABE, the adoption of CP-ABE may result in an inescapable security breach known as the abuse of access accreditation (for example, decoding privileges). Here, we focus on two key cases in which a cloud client's access qualification is abused by a semi-believed specialist. CryptCloud+, a distributed storage platform with white-box discernibility and review, is proposed as a way to limit the exploitation of the system. Additionally, we demonstrate the framework's usefulness by conducting studies.

With the advancement of technology and the confinements of the good old medical services framework, an unplanned structure for social insurance is needed. We've witnessed a growing interest in and preference for cloud-based software development in the human services sector to manage and meet existing and future demands in social insurance administrations. We propose a cloud-based framework for medical services that is adaptable, safe, efficient, practical, and protected. For the administration EHR framework, we've presented a safe and effective structure in which fine-grained access control is commonly controlled by multi-authority ciphertext property-based encryption (CP-ABE), close by many levels of information structure to permit access control arrangements. Egovernment distributed computing is a major advantage for Saudi Arabia's top officials, who will be able to grow up their social insurance sector through the proposed framework.

Published: April 2024

Esta investigación propone una nueva metodología para analizar el proceso de transferencia de información científica desde que se producen los hallazgos en institutos y grupos de investigación hasta que llega a la sociedad. Este estudio de caso, se centra en el análisis de las informaciones científicas surgidas en la Comunidad de Aragón. Como trabajo de campo, se analizaron notas de prensa de la Unidad de Cultura Científica de la Universidad de Zaragoza y se contrastaron con su cobertura en medios audiovisuales. Los resultados muestran una escasa presencia de noticias científicas en los principales informativos, con mayor interés en cadenas regionales públicas. Como conclusión, se comprueba que la falta de recursos audiovisuales y espacio limitado dificultan la difusión en televisión, mientras que la visibilidad en medios regionales se ve influida por el criterio de proximidad informativa y las convocatorias institucionales.

Historical evolution of ethical and legal aspects in aromatherapy in Brazilian Nursing
Authors: Gomes Alexandro Ferreira
Published: April 2024

Introduction: Aromatherapy is an ancient practice performed by nurses, initially practiced by Florence Nightingale to calm wounded soldiers in the war and later consolidated by Marguerite Maury, considered an icon of modern Aromatherapy. This practice has sparked interest today due to its inclusion in Integrative and Complementary Health Practices and its congruence with the holistic vision present in nursing education and practice, which aims for care that reaches biopsychosocial and spiritual aspects. Objective: To describe the historical trajectory of ethical and legal aspects of nurse practice in Aromatherapy in Brazil. Material and Methods: This is a narrative review, in which publications from the Ministry of Health, the Federal Nursing Council, and Regional Nursing Councils were fully read, tracing a historical line of the legal developments of nurse practice in Aromatherapy. Searches used the keywords: aromatherapy, integrative practices in health, nursing, combined by the boolean indicator "and". These were organized in a chart that allows analyzing the evolution of these legislations over time. Results: Nursing, through its ethical and legal aspects, is a profession supported for the use of Aromatherapy in the nursing process in various health/disease situations. Nurses are allowed to prescribe essential oils, provided they have the training to do so that considers patient safety, and the development of institutional protocols is recommended. Nursing work in Aromatherapy has been recently regulated, with a minimum course load of 120 hours/lesson, in the form of free courses. Discussion and Conclusion: The ethical and legal aspects of Nursing in Aromatherapy have advanced, with solid ethical and legal bases. However, the lack of mandatory specialized education in the standards of the Ministry of Education, with courses subjected to evaluation and with a course load of over 360 hours/lesson, could mean a step back in the pursuit of in-depth knowledge, scientific research, and innovation. It is concluded that the regulation of Nursing in Aromatherapy is an important pathway opener for entrepreneurship, as well as consolidates its action as an integral member of the Integrative and Complementary Practices in Health.
Comparison between the Chemical Profiles of Hydrosols and Essential Oils of French Lavender, Geranium, and Basil
Authors: Rocha Nathan Barros da , Rangel Ellen Thanus , Silva Antônio Jorge Ribeiro da , Simas Daniel Luiz Reis
Published: April 2024

The essential oil production process consists of distilling plant parts with water, where steam removes the volatile components from the material. Condensing this steam from the extraction results in the formation of two phases, an organic (essential oil) and an aqueous (hydrosol). Hydrosols or floral waters are not true solutions but dispersions with water as the continuous medium.1 Although they are market products, there is no regulation regarding their quality control, and there is a lack of compositional studies. Thus, this work aims to study the relationships between the chemical compositions of the two products that have the same raw material. Commercial samples of essential oil and hydrosol from French Lavender (Lavandula dentata), Geranium (Pelargonium graveolens), and Basil (Ocimum basilicum) were kindly provided by Haje Organic Inputs. The organic components of the hydrosols (HL) were obtained through partitioning with 250 ml of hydrosol and 30 ml (3x) of petroleum ether. The ether was then evaporated with the aid of a rotary evaporator, and the resulting extract was dried with Na2SO4 and weighed. The hydrosol extracts and essential oils were analyzed by GC-FID and GC-MS.2 It was noted that only compounds with oxygenated functions were present in the HL, similar to those in the EO, varying only in isomerism or oxidation degree. The substances composing the EOs were divided into two groups called hydrocarbons (HC) and oxygenated (OXI), and the fraction each composed of the oils was calculated. The results were 21.30% HC and 78.16% OXI for French Lavender, Geranium 8.54% HC and 80.32% OXI, and for Basil was 51.22 HC and 48.33 OXI. And the percentage of organic components in each HL is 0.0072%, 0.0138%, and 0.0223%, respectively. It is observed that the OXI fraction content of the oil does not influence the yield of the HLs, as Lavender and Geranium oils show a high OXI percentage and low recovery yield. It can be concluded that the HLs are heterogeneous samples, that the oxygenated function substances are the only ones present in their composition, and that they originate from the corresponding essential oil. The yield is not determined by the chemical composition, but it is pointed out to be due to operational factors of the production. The results prove that essential oils and hydrosols from the same plant do not always have corresponding chemical compositions. Therefore, in some cases, they should not be applied with the same therapeutic purpose.

The concept of the “short 20th century” as an interpretative model for studying the socio-political history of Indonesia
Authors: Kyrchanoff Maksym Waler'evich
Published: April 2024

The purpose of this study is to analyze the “short 20th century” concept as an interpretative model of modern historical science that claims to be universal. The author analyzes the concept of the “short 20th century” proposed by Eric Hobsbawm. The subject of the article is the concept of the “short 20th century”, the object is the possibility of its application and transplantation into Indonesian historical research. The novelty of the study lies in the analysis of the concept of the “short 20th century” as an interpretative model that allows us to analyze the features of the historical, social and cultural development of Indonesia in the context of those transformation processes that were launched by the development of nationalism, modernization and secularization. It is assumed that the interpretive models proposed by Western historians have a claim to universality, although the effect of its transplantation into non-Western historical contexts may be limited. The article analyzes 1) the features of the social and economic components in the transformation of Indonesia during the “short 20th century”, 2) the role of the factors of nationalism and Islam in political changes within the framework of political competition and the confrontational model of relations between the Ummah and the ruling elites, 3) the consequences of “short 20th century” for the subsequent history of the region. The article shows the potential of the concept of the “short 20th century” for analyzing the history of social and political transformations in Indonesia. The results of the study suggest that the effect of using the concept of the “short 20th century” is limited. The author believes that this interpretative model can be effective relatively and useful for analyzing social and political dynamics through the prism of confrontation between secular and religious institutions as sources and drivers of change.
