Published: August 2024

Total X-Ray Fluorescence (TXRF) is a non-destructive technique for the characterization of metallic contaminants on bare silicon wafers. TXRF is sensible to roughness leading to a diffraction phenomenon. In this study, the effects of roughness on TXRF analysis were evaluated with various rough silicon wafers produced by microelectronic processes of grinding, wet cleaning and chemical mechanical polishing. TXRF parameters rise as roughness increases, starting from 3 nm RMS (Root Mean Square) roughness. On spectra, characteristic Si (silicon wafer) and W (TXRF anode) peaks widen. Secondary peaks, sum/escape peaks appear, inducing interferences with Al, Cu, Zn and background noise increases as well. Through intentionally contaminated grinded wafers (RMS 12 nm) by spin-coating at selected concentrations, it was observed that most of the elements are quantified at 1 × 1012 at/cm2. At concentrations of 1 × 1010 at/cm2 and 1 × 1011 at/cm2, only few elements are quantified due to the elevated background noise and interferences.

Destination sequenced distance vector routing taking into account signal to noise for flying ad hoc network
Authors: Thai Thu Thuy , Pham Gia Vu , Trinh Anh  Truc
Published: August 2024

Flying ad hoc networks (FANET) are becoming increasingly popular in both military and civilian applications. The primary characteristic of FANET is their high mobility, which results in a frequently changing topology. This is a significant challenge for protocols that control data transmission from nodes to base stations. Consequently, many research groups have recently been attracted to the study of data transmission control protocols in FANET, typically routing protocols. This paper presents an application of Destination Sequenced Distance Vector (DSDV) routing protocols for FANET. We improved the DSDV routing protocol by considering the signal-to-noise ratio (SNR) when discovering new routes. Simulation results show that the improved DSDV algorithm outperforms the traditional DSDV algorithm in terms of network throughput, end-to-end delay, and SNR.

Published: August 2024

Na contemporaneidade, as atividades industriais aspiram em sua grande maioria uma agressão ao meio ambiente, especificamente quando é utilizada matéria-prima e/ou outros insumos extraídos diretamente da natureza. Ao estudarmos o desenvolvimento do setor mineiro-cerâmico em nosso país percebe-se que as primeiras constatações estão relacionadas às condições de fornecimento da matéria-prima, pois a cerâmica vermelha exige qualidade desse material e sua extração tem se dado de forma desordenada, comprometendo bases sustentáveis em seu desenvolvimento. A indústria de cerâmica vermelha do Ceará constitui-se basicamente pela organização de empreendimentos de pequeno e grande porte, em sua maioria localizada principalmente na área rural. A pesquisa objetiva de forma mais geral avaliar os impactos ambientais da atividade ceramista na comunidade de Espinho no município de Limoeiro do Norte-CE, de forma específica propõe-se identificar os impactos ambientais decorrentes da produção ceramista e diagnosticar junto às famílias as mudanças no cotidiano de suas vidas com a situação da fuligem que adentra suas casas. Traçando como metodologia a realização de revisões bibliográficas, trabalho de campo, anotações do caderno de campo, breves entrevista com famílias moradoras do entorno e atingidas pela emissão de fuligem como também os registros fotográficos. Vale ressaltar que esse ramo de atividade contribui para uma movimentação considerável desse setor cearense, pois é caracterizado na essência pela sua informalidade no trabalho, com pouca especialidade em sua produção, predominando uma mão de obra sem exigência de qualificação e com uma alta rotatividade no quadro de colaboradores. Mesmo diante desta realidade conclui-se que se faz necessário uma fiscalização mais rígida dos órgãos de competência ambiental quanto ao funcionamento e localização das indústrias de cerâmica vermelha, pois a pesquisa em curso aponta impactos ambientais que ocorrem desde a extração do material predominante (argila), como também as questões que envolvem a saúde humana como é o caso das famílias da comunidade de Espinho que residem no entorno da cerâmica e sofrem com a emissão de fuligem pela queima dos fornos.

Introduction: Sleep is fundamental to the quality of life and can affect individuals' well-being and mental health. Objective: This study analyzed sleep quality and job satisfaction among Spanish nurses following the COVID-19 pandemic. Materials and Methods: A cross-sectional study was conducted using the Pittsburgh Sleep Quality Index (PSQI), Font Roja Job Satisfaction Questionnaire, and sociodemographic and work-related variables. A “snowball” sampling method was employed through social media dissemination. Results: The mean PSQI score was 9.75 ± 4,36 points. The poorest sleep quality was identified in participants without dependents (p=0.031; β=3.329; 95% CI=0.035-6.354) and those with dependents other than children (p=0.022; β=4.121; 95% CI=0.575-7.667). However, having a Ph.D degree (p=0.001; β=-3.406; 95% CI=-5.503-1.309) or specialist degree (p=0.021; β=-1.639; 95% CI=-3.031- -0.247) was associated with better sleep quality. Higher job satisfaction was found among women (p=0.034; β=0.104; 95% CI=0.007-0.201) who did not work with COVID-19 patients (p=0.049; β=-0.085; 95% CI=-0.174- -0.003). Discussion: Improving working conditions, such as the nurse-to-patient ratio and distribution of work shifts, is crucial to enhancing nurses' sleep quality. Conclusions: Spanish nurses reported poor sleep quality. Not having dependents or having dependents other than children were risk factors for poor sleep quality. Job satisfaction was higher among women who did not work with COVID-19 patients. No relationship was found between job satisfaction and sleep quality.

Published: August 2024

ABSTRACT Integrated production systems have emerged as a sustainable production strategy in intensifying land use with minimal impact on ecosystem functions. This study used precision agriculture tools to investigate the spatial variability of soil and vegetation properties in an integrated crop-livestock-forestry (ICLF) and in an integrated livestock-forestry (ILF) area of São Carlos city, SP, Brazil. Consequently, the following were assessed: (1) the soil physicochemical properties, (2) the electrical resistivity, and (3) the attributes of the Eucalyptus urograndis crop comprising the study area. Samplings were performed in (1) August 2021 at depths of 0-0.2 and 0.2-0.4 m; (2) October 2021 at depths of 0-0.5, 0-1.0, and 0-2.0 m; and (3) April 2021 and April 2022. Results indicated that the values for soil fertility parameters were suitable for crop development and presented low spatial variability. Soil analyses indicated low acidity, high levels of organic matter, average cation exchange capacity, phosphorus and potassium contents, high base saturation, and calcium and magnesium levels. However, locations with greater spatial variability for calcium were observed, reflecting cation exchange capacity and base saturation variability. Soil granulometry and electrical resistivity had a low spatial variability at the surface layer. Even without differences in the soil properties, there was a difference of 15% in the larger wood volume in the ILF then ICLF system.
HARNESSING PHONON WAVE RESONANCE IN CARBYNE-ENRICHED NANO-INTERFACES TO ENHANCE ENERGY RELEASE IN NANOENERGETIC MATERIALS
Authors: Lukin Alexander , Gülseren Oğuz
Published: August 2024

This paper introduces a new nanotechnology-driven approach that provides a transformative pathway to substantially enhance the energy release efficiency of nanoenergetic materials (nEMs) without altering their chemical composition. The groundbreaking concept involves strategically harnessing, self-synchronized collective atomic vibrations and phonon wave resonance phenomena within the transition domain's interconnecting nanocomponents. A key novelty is the incorporation of meticulously engineered two-dimensional-ordered linear-chain carbon-based multilayer nano-enhanced interfaces as programmable nanodevices into these transition domains, facilitated by advanced multistage processing and assembly techniques. These programmable nanodevices enable unprecedented control over the initiation, propagation, and coupling of self-synchronized collective atomic vibrations and phonon waves, unleashing powerful synergistic effects. Central to this approach is the bidirectional, self-reinforcing interaction between precisely tailored nano-architectures and phonon dynamics within the multilayer nano-enhanced interfaces. This synergistic coupling facilitates the rational programming of energy transfer pathways, granting access to
previously inaccessible energy reserves inherently locked within the nEM systems. To optimally activate and harness these synergistic mechanisms, a strategic combination of cutting-edge methods is judiciously employed. These include energy-driven stimulation of allotropic phase transformations, surface acoustic wave-assisted manipulation at micro-/nanoscales, heteroatom doping, directed self-assembly driven by high-frequency electromagnetic fields, and a data-driven inverse design framework. Notably, by leveraging a data-driven inverse design strategy rooted in multifactorial
neural network predictive models, we uncover previously hidden structure-property relationships governing the nano-enhanced interfaces. This novel data-driven "nanocarbon genome" approach enables rational maximization of energy release efficiency in nEM systems. Overall, this transformative nanoscale concept not only unlocks unprecedented high-energy functionalities but also ushers in significant improvements in environmental sustainability and operational safety for nEMs.

This paper looks at how environmental changes may affect infrastructure safety, and it makes observations on the benefits to minimising embodied carbon if only rates of infrastructure failure can be reduced. The safety implications linked to popular design strategies are discussed.
Axial compression behaviour of square steel tubes encased by and filled with high-strength recycled aggregate concrete
Authors: Niu Haicheng , Xie Shu , Qing Yanying , Huang Minghui , Fan Yuhui
Published: August 2024

The axial compression behaviour of square steel tube (SST) columns encased with recycled aggregate concrete (RAC) and filled with RAC (RAC-encased RACFSST) columns was investigated. Using high-strength concrete, five specimens were tested under axial compression until failure. The experimental parameters included the coarse aggregate type, stirrup spacing, wall thickness of the SST and the existence of cross-tie bars in the SST. The failure mode, load–displacement curves, load–strain curves and ductility of the composite columns were obtained. The impacts of the various parameters on the mechanical performance of the RAC-encased RACFSST columns were evaluated. The failure modes of the composite columns were comparable. The inclusion of RAC enhanced the load-bearing capacity (LBC) of the column, but negatively affects its ductility and deformation capacity. Increasing the wall thickness of the SST and reducing the stirrup spacing significantly improved the axial compressive performance of the columns, as mainly reflected in the axial compressive capacity and ductility, respectively. Cross-tie bars inside the SST improved the LBC and deformation capacity. The axial bearing capacities of the columns and those in other studies were determined using existing codes. The computed results were very consistent with the experimental data.

Amyloid can accumulate in the liver, spleen, kidney, heart, nerves and blood vessels and cause different clinical syndromes such as cardiomyopathy, hepatomegaly, proteinuria, macroglossia, ecchymoses, neuropathy, renal failure, hypertension, autonomic dysfunctions and corneal abnormalities. In this case report, we present a 73-year-old male patient who presented to our clinic with dysphagia due to macroglossia for 2 years and had no other symptoms.
Clausal nominalization and embedded questions in Japanese
Authors: Nasu Norio , Akimoto Takayuki , Shimamura Koji , Yoda Yusuke
Published: August 2024

Investigating the structure of nominalized embedded questions (EQs) in Japanese, this paper proposes that they contain nP and DP on top of CP. Previous studies on clausal nominalization argue that CPs are nominalized by directly merging D. However, the availability of prenominal modification indicates that Japanese nominal EQs involve nP and, in some cases, DP. The functional head n nominalizing an interrogative CP is divided into semantically vacuous and semantically active classes. The semantically vacuous n lacks its own denotation but simply converts an interrogative CP into a nominal category. EQs nominalized the semantically active n do not denote pure questions. Some have a structure similar to the noun complement clause that involves a silent noun semantically equivalent to ‘question’ or ‘issue’. Others express possible answers to questions. EQs nominalized by the semantically active n project up to DP. The blocking effect on extraction and the co-occurrence with a pronoun support the presence of the DP layer. The presence of the DP in Japanese EQs suggests that the NP/DP-dichotomy advocated by Bošković (2005; 2008; 2009) can be relaxed. Japanese is a hybrid language. While it is similar to NP-languages in that it does not have overt articles, its noun phrase still involves the DP layer.
Determination of deformation modulus and characterization of anisotropic behavior of blocky rock masses
Authors: Ahrami O. , Javaheri Koupaei H. , Ahangari K.
Published: August 2024

The anisotropy in the deformational behavior of blocky rock masses has been comprehensively investigated. The uniaxial deformation modulus was selected as the key parameter. This modulus is generally anisotropic and depends on the loading direction, as well as on the properties of the intact rock, joints, and joint setting. Representative volumes of blocky rock masses were numerically simulated using the discrete element method and were loaded uniaxially in various directions. Subsequently, the failure mode and the deformation modulus were studied for different loading directions and various relative joint settings. A new nonlinear, stress- dependent stiffness matrix for joints was introduced, incorporating the surface conditions of the joints in terms of the Joint Roughness Coefficient (JRC) and the properties of the intact rock materials in terms of the Uniaxial Compressive Strength (UCS). The results of the assessments are presented in the form of rose diagrams, showing variations in the deformation modulus of the blocky rock mass that depend on the joint’s JRC, the intact rock’s UCS, and the structure of the rock mass in term of the relative joint angle. Also, the expected degree of anisotropy for various joint surface conditions and uniaxial compressive strengths of intact rock were introduced. In the Geological Strength Index (GSI) table, results are classified such that assigning a value to the JRC for each class of joint surface conditions allows for the corresponding deformation modulus and degree of anisotropy. According to this chart, it is deduced that the effect of joint roughness on the deformation modulus of blocky rock masses is greater than that of the intact rock UCS. The results support the hypothesis that a blocky rock mass has a critical strain that is independent of the loading angle (θ) and the orientation of the third joint set (α).

Published: August 2024

The use of dry methods of processing and beneficiation of mineral raw materials is one of the promising areas, as this approach to concentrate production is less energy-consuming, less labor-intensive, and economically beneficial. The paper presents experimental studies on preliminary dry separation of Arkachan deposit ores to determine the quality of beneficiation of the separation products. The studies on dressability were carried out on pilot plants for dry ore processing and beneficiation: combined impact crusher DKD-300, centrifugal mill TsMVU-800, pneumatic separator POS-2000. Processing of the obtained separation products by pneumatic separation and screening according to the sequential flow chart of crushing and grinding was carried out in laboratory conditions at a gravity concentration table SKO-0.5. The GRG test was performed at an ITOMAK-0.1 centrifugal concentrator using a sequential grinding circuit. The GRG test showed that for more efficient gravity separation of gold, up to total gold recovery of 73.91%, the degree of grinding up to 80% passing 0.071 mm was required, allowing obtaining a gravity concentrate graded at 70.28 g/t gold.

Published: August 2024

Block stone excavation is a key aspect of the building materials industry, important for providing construction with durable materials and when giving aesthetic solutions to various structures and design elements. However, when excavating stone (using drilling and blasting), it is necessary to maintain its integrity for further processing and use. The conditions required for applying the method of blasting separation (split off) of stone blocks from hard rock mass were considered, which is important for improving the quality of blasted stone blocks. The rational parameters of stone block blasting with Granilen elastic tubular charges (Granilen ETCs) are presented. An approach to the preliminary assessment of stone block fracturing zone under various explosive loading regimes was determined. The relationship between the consumption of explosives and fracturing of stone blocks at possible blasthole spacing was considered. The mechanism of creating an extended rupture plane in a rock mass was studied. The decisive role of stress waves in the formation of an extended main rupture along the line of blasthole charges was established. It was shown that it is possible to localize the zone of induced fracturing by regulating the conditions for the interaction of stress waves. The results of numerical modeling of stress fields at blasting a single charge and a two-charge Granilen ETC system are presented, which made it possible to assess zones of induced fracturing and the conditionsfor the formation of a main rupture. Blasting effectiveness increases significantly due to the orientation of the expected stone block separation line parallel to the plane of the best rupture, taking into account the anisotropy of the physical and mechanical properties of granites. The study confirms the feasibility of increasing the yield of commodity blocks when selecting rational blasting parameters.
Perspectives on the 1972–1973 massacre and post-conflict reconstruction efforts in Burundi
Authors: Nsengiyumva Isidore
Published: August 2024

How do we repair and reconcile a society broken multiple times by years of political violence and cyclic mass atrocity events? Reconciliation processes in post-conflict societies tend to favour state-led peace processes to aid individuals and communities alike to heal, make sense of the past while also imagining and forging an interdependent future together. The Burundi Truth and Reconciliation Commission (TRC), established in 2014, has the mandate to investigate past crimes and mass violence events dating from 1885 to the 4 December 2008 ceasefire with the aim of aiding truth-telling, reconciliation and transitional justice. The paper comments on how the TRC shapes ongoing healing, reconciliation and transitional justice efforts in post-conflict Burundi. This paper uses desk-based research to draw insights from documented works and reports of the TRC between 2018 and 2022. The TRC’s findings sparked multiple narratives and public discourse in the Senate which further led to the re-examination of the 1972‒1973 massacre, the legacy of colonisation and its impact in cementing ethnic divisions that led to cyclic mass violence in Burundi.
Strain Analysis of the Shear Zones of Ambaji Granulite in the South Delhi Terrane of the Aravalli-Delhi Mobile Belt, NW India, and its Implication on the Exhumation of the Mid-lower Crustal Rocks
Authors: Saraswati Ragini , Sharma Neeraj Kumar , Biswal Tapas Kumar
Published: August 2024

Kilometer-scale granulite pockets bounded by shear zones occur within low to medium-grade rocks of the Precambrian mobile belts. Emplacement kinematics of such deeper rocks is reflected in the strain pattern of the associated shear zones. We have carried out the strain analysis of the shear zones of the Ambaji granulite in the Neoproterozoic South Delhi Terrane of the Aravalli-Delhi Mobile belt, NW India. The Kui-Chitraseni shear zone is the main strand and the other shear zones imbricates from it. The shear zones record an earlier phase of thrust kinematics in granulite grade that was primarily responsible for exhuming the rocks from the mid-lower crust. Later a strike-slip shearing was superimposed on those shear zones when the retrogression of the granulites took place. Strain and vorticity analysis of strike-slip shear indicates a transpressive strain consisting of pure and simple shear in different proportions, that led to further extrusion of granulite. Strain gradually diminishes towards the termination points of each shear zone and from center to wall. We have modeled the shear zones in the form of a splay which initiated as a leading thrust splay, transformed into a strike-slip transpressional splay, and subsequently as an extensional termination splay. Extensional splay further contributed to tectonic erosion and exhumation of granulite.
High Resolution Strontium Isotope Stratigraphy of L-III Reservoir of Mumbai High and adjoining Cluster 7 areas of Mumbai Offshore Basin, India
Authors: Rathore Shakti Singh , Gupta Piyush , Sarkar Argha Narayan
Published: August 2024

High degree of reservoir heterogeneity has always been problematic in the identification and chronostratigraphic mapping of individual layers in a thick limestone sequence, especially when there is poor preservation of index fossils for thin sub-layers in the sequence. The multi-layered Miocene L-III reservoir of Bombay Formation in Mumbai High and adjoining southwestern area of the Mumbai offshore basin of India have suffered from similar issues due to lack of absolute ages and, therefore, the lack of highresolution chronostratigraphy for its individual thin limestone layers. The present study attempts to establish high-resolution chronostratigraphic age constraints of different sub-units, namely A, B, C, D, and E layers, of the L-III unit, using strontium isotope stratigraphy of carbonate (core and cutting) samples cut from 7 wells in Mumbai High and five wells in Cluster-7 area southwest to Mumbai High. The study provides a geochronological age range of ~2.1 Ma for the L-III unit, with the top of L-III in Mumbai High South assigned at 16.6 Ma based on Strontium isotopic analysis. The study has further helped in assigning absolute ages of individual layers of the L-III reservoir, with the A1 sub-unit at 16.6-16.8 Ma, A2 between 16.9-17.9 Ma, B sub-unit at 18.0 Ma and C & D sub-units between 18.2-18.3 Ma. Layer E of the L-III unit was dated to be 18.5-18.6 Ma, and the L-IV top has been assigned to be at 18.7 Ma. The study also correlated the ages obtained in the Mumbai High region with the studied wells southwest of Mumbai High and provided high-resolution strontium isotopic chronostratigraphy for equivalent sub-layers A to E in the Cluster-7 area SW to Mumbai High. These ages have provided new numerical age constraints for the L-III and its sub-units for the first time, are correlatable across different well sections, and are in perfect agreement with reported biostratigraphic ages for the Bombay Formation and the sub-units within. This has important implications for effective reservoir management and performance prediction for the hydrocarbon-producing pays in the studied L-III reservoir unit.

Introduction: Pregnancy is a period of transformations that can interfere with the pregnant woman's genital image (GI) and sexual function (SF). There may be fluctuations in GI and SF according to the gestational trimesters. However, it is still uncertain whether or not there is a decrease in these two variables throughout pregnancy. Objective: Compare GI and SF in the second and third trimester of pregnancy. Methods: The Female Genital Self-Image Scale (FGSIS) and Female Sexual Function Index (FSFI) questionnaires were applied to analyze GI and SF, respectively. Each participant answered the questionnaires in the second and third trimester of pregnancy. Quantitative variables were analyzed descriptively using simple frequencies and percentages (categorical variables), and mean and standard deviation (numeric variables). To check the normality of the data, the Shapiro-Wilk test was performed. To compare the scores obtained related to GA and SF, the Wilcoxon test was used, with a significance level of 5%. Results: 10 pregnant women were included in the study. Regarding the GI assessment, the average score on the FGSIS questionnaire for pregnant women was 22.0 (±3.6) and in the reassessment it was 14.4 (±4.5), where higher scores demonstrate a more positive GI. Furthermore, the participants' SF had an average of 25.5 (±6.6) in the evaluation and 19.5 (±12.4) in the reevaluation, through the total score of the FSFI questionnaire, in which lower scores represent worsening from SF. In other words, from the second to the third gestational trimester, pregnant women indicated a worsening in GI and SF, except for the desire and lubrication domains. Half of the pregnant women (n=5) showed signs of sexual disfuction in the evaluation and 80% (n=8) in the reevaluation. The domains with the worst indicators were desire and orgasm. Conclusion: SF and GI showed significant worsening throughout the pregnancy cycle of pregnant women participating in this study.

BACKGROUND: Рrematurity is the leading factor of nervous system damage during childbirth. This article presents an analysis of cases of birth injuries in newborns with extremely low body weight, with a study of the structural features of the dura mater and comparison of the results with those of full-term newborns.
AIM: To identify the distinctive features of the structure of the dura mater in newborns with extremely low birth weight and full-term newborns and establish the association between the structural features and its damage during childbirth.
MATERIALS AND METHODS: A retrospective sampling study was conducted. The main group included newborns with extremely low body weight, and the comparison group consisted of full-term newborns with an established fact of birth trauma. The dura mater was studied from the region of the tentorium velum, falx, and sinus drainage; they were compared with the counting of type I collagen fibers using light and polarization microscopy and morphometry.
RESULTS: In extremely low birth weight newborns, severe intradural hemorrhages were found in the dura mater, indicating its overextension due to the configuration of the head. The dura mater includes loose connective tissue, consisting of short type III collagen fibers. In the comparison group, the severity of subarachnoid hemorrhages in the projection of the sutures corresponded to the severity of damage to the septal parts of the dura mater. The dura mater consists of dense fibrous connective tissue and predominantly type I collagen. Morphometry revealed anisotropy in polarized light in 2%–5% of fiber collagens in the main group and 30–50% of fiber collagens in the comparison group. Statistically significant indicators were identified (p 0.001).
CONCLUSIONS: The structural features of newborns with extremely low body weight indicate the morphofunctional immaturity of the connective tissue of the dura mater, which affects its strength characteristics and leads to damage during any type of birth. Consequently, this injury is an injury to a painfully altered organ and therefore does not qualify for the severity of harm to health.

Authors: Boscardin Mariele , Breitenbach Raquel , Brandão Janaína Balk
Published: August 2024

O objetivo deste trabalho foi analisar a evolução do debate acadêmico acerca dos estilos de consumo alternativos, considerando seus conceitos, características, princípios e eixos temáticos abordados. Para tanto, consideraram-se como estilos de consumo alternativos: freeganismo, locavorismo, flexitarianismo e climaterianismo. Metodologicamente, realizou-se uma pesquisa bibliométrica quantitativa e qualitativa. Como base de dados, foi utilizada Scopus, considerando as seguintes palavras-chave para busca “freegan*” ou “locavor*” ou “flexitarian*” ou “climatarian*”. Após utilizar os critérios de inclusão e exclusão (documentos do tipo artigo e alinhamento com o tema), foram selecionados 59 artigos, sem delimitação temporal. Em 2009, registrou-se o primeiro artigo sobre o tema, mantendo uma média de 2,75 artigos por ano até 2021, quando ocorreu um aumento na produção científica sobre o tema, saltando para 12 estudos naquele ano. Ao longo desse tempo, o flexitarianismo, seguido do locavorismo foram os estilos mais estudados, indicando maior interesse da comunidade científica. Em relação à análise qualitativa, foram classificados três eixos temáticos em torno dos estilos de consumo alternativos: a) características, princípios e ideologias; b) motivações; c) reflexos para a sociedade e os mercados agroalimentares. Por fim, destaca-se que os estilos alimentares alternativos podem impactar nos mercados agroalimentares de modo a incentivar sistemas produtivos mais sustentáveis e formas de comercialização justas.

SOBRE LA TEORIA CUANTICA DE LAS MOLECULAS
Authors: Poveda Arnulfo , Villaveces José Luis , Moyano Gloria Esperanza
Published: August 2024

Se muestra que las partes conocidas de los términos espectrales moleculares, correspondientes a la energía de los movimientos electrónicos, rotaciones nucleares y vibraciones nucleares, pueden obtenerse sistemáticamente como los miembros de un desarrollo en serie de potencias de la raíz cuarta de la relación entre la masa del electrón y la masa promedio de los núcleos. El procedimiento lleva a unas ecuaciones para las rotaciones que representan una generalización de la hipótesis de Kramers y Pauli (del trompo con momentum angular intrínseco). También se obtiene una justificación de las observaciones presentadas por Franck y Condon sobre la intensidad de las líneas de banda. Esto se muestra para el caso de las moléculas diatómicas.
EL POSTULADO DE LAS PARALELAS
Authors: Moreno-Armella Luis
Published: August 2024

Se describe el camino seguido desde Euclides hasta Hilbert en la construcción de la geometría como una ciencia teórica. Se indica la intención filosófica, que se encuentra ya clara en Aristóteles, de construir ciencias demostrativas, lo cual condujo necesariamente a la exploración de las proposiciones como elementos constitutivos de un sistema axiomático para la geometría, pasando de lo ontológico a lo lógico. En este proceso tuvieron profunda importancia los intentos de demostración del postulado de las paralelas, que muestran cómo se pasó de la "verdad euclídea" a la "consistencia hilbertiana".

DISTRIBUCION DE LA BIOMASA PLANCTONICA , EN LA COSTA PACIFICA COLOMBIANA ENTRE NOVIEMBRE DE 1997 Y NOVIEMBRE DE 1998
Authors: Criales-Hernandez María Isabel
Published: August 2024

Se determinaron las distribuciones de las biomasas fitoplanctónicas en aguas del Pacífico colombiano (Bahía Humboldt a Cabo Manglares) a partir de 120 muestras de plancton, recolectadas en tres cruceros entre noviembre de 1997 y noviembre de 1998. Se elaboraron mapas de las biomasas fitoplanctónicas y se encontró que en noviembre-diciembre de 1997, durante la ocurrencia de un evento "El Niño"-Oscilación del Sur, las concentraciones fitoplanctónicas en promedio fueron relativamente altas (10.11-19.97 mg/L). La subárea central se ve favorecida con valores promedios altos de fitoplancton (11.61-20.83 mg/L), quizás debido a las descargas de los ríos que allí desembocan.

A Case Study of the Management of Childhood Atopic Dermatitis Applying Ayurveda Treatment
Authors: Khatri Arun Naphe , Rathi Renu , Jumle Rahul , Borse Sayali
Published: August 2024

Background: Chronic inflammatory skin disease Atopic Dermatitis (AD) compromises the skin barrier and decreases cell-mediated immune activity. The acute stage of this condition is characterised by erythema, edema, vesicles, and fluid leakage, while the chronic stage is marked by thickening and hyperpigmentation, known as lichenification. The prevalence of skin conditions is increasing daily. Other medicinal methods offer just a partial cure, though. Skin issues can be effectively managed with the help of Ayurveda. Vicharchika can be likened to atopic dermatitis, exhibiting similar characteristics as described in ancient Ayurvedic texts. Aim: The study aims to assess the efficacy of Ayurvedic treatment in managing Atopic dermatitis. The study aims to evaluate the impact of Ayurveda intervention on the severity of symptoms and quality of life of paediatric patients with Atopic dermatitis. Methods: The study involved a 4-year-old girl presenting with scaly, dry, pruritic skin, reddish, blackish excoriated lesions, and oozing. The patient sought treatment at the Kaumarbhritya outpatient section of Mahatma Gandhi Ayurved College, Hospital and Research Centre. The treatment plan spanned two weeks of Ayurvedic medicines and dietary recommendations, followed by a one-month inpatient phase. Inpatient care included dietary modifications, internal medicines, Snehapana (ghee consumption), Kushtahara (itch-alleviating), and Kandughna (anti-pruritic) Dravyas. Results: The Ayurvedic treatment yielded positive results for the patient. Notable improvements were observed, including a reduction in excoriation, irritation and dryness. The severity of the condition was assessed using SCORAD SCALE, which showed a decline from the initial score of 46.3 to a post-treatment score of 17.8. Additionally, the patient’s condition improved significantly, transitioning from severe eczema to a state of near clarity as assessed by the POEM SCALE. Conclusion: This study demonstrates the efficacy of Ayurvedic treatment in effectively managing atopic dermatitis in pediatric patients. The positive outcomes observed, both in terms of symptom relief and improved quality of life, underscore the potential of Ayurveda as a valuable therapeutic approach for addressing chronic inflammatory skin disorders like atopic dermatitis. Maintaining dietary restrictions and ongoing internal medication emerged as essential strategies to prevent the recurrence of the condition.
