САКСОФОННИЙ КВАРТЕТ У ТВОРЧОСТІ УКРАЇНСЬКИХ КОМПОЗИТОРІВ 80–90-х РОКІВ ХХ СТОЛІТТЯ
Authors: Du Bohao
Published: January 2025

Мета статті полягає у дослідженні жанрово-стильових тенденцій розвитку жанру саксофонного квартету в творчості українських композиторів 80 – 90-х років ХХ ст. У зв’язку із цим методологічним підґрунтям наукової розробки слугували: комплексний метод, системний і культурологічний підходи – в осмисленні композиторської та виконавської творчості для квартету саксофонів як складових української камерно-інструментальної музики, окресленого хронологічного відтинку; еволюційний – в розкритті історичних передумов сучасних інноваційних процесів у саксофонних квартетних композиціях українських авторів; аналітичний та типологічний – при виявленні жанрово-стильових особливостей окремих творів аналізованого жанру та об’єднання їх у типологічні групи. Новизна статті полягає у панорамному дослідженні жанрово-стильових процесів розвитку квартету саксофонів у творчості українських композиторів 80 – 90-х років ХХ ст. Висновки. На основі дослідження квартету саксофонів в українській музичній культурі відзначено, що його формування та стрімкий еволюційний розвиток зумовлені створенням та широкою концертною діяльністю Київського квартету саксофоністів (1985) під керівництвом Ю. Василевича. На основі аналітичної характеристики окремих композицій для квартету саксофонів, створених українськими композиторами упродовж 1980 –90-х років, відзначено, що вони написані як для традиційного складу ансамблю (О. Козаренко, Ж. Колодуб, В. Маник, В. Рунчак, К. Цепколенко), так і для мішаного, в якому із групою саксофонів досить своєрідно поєднуються бандура, ударні (І. Тараненко). Кожен із проаналізованих у статті творів для квартету саксофонів має оригінальну концепцію, пов’язану із загальною тенденцією естетики постмодернізму, з притаманним йому тяжінням до полістилітики та різноманітних синтезованих форм художньо-музичного висловлювання. Стильові уподобання авторів пов’язані із органічним поєднання рис неофольклоризму та авангардних композиторських технік (О. Козаренко, В. Маник), джазової стилістики із сучасною мовою (І. Тараненко), втілення складних філософсько-психологічних образів (К. Цепколенко, В. Рунчак), потребують від музикантів володіння широким спектром акласичних виконавських прийомів: гри чвертьтонів, субтонів, різноманітних glissando, tremolando, хроматичних cluster, сонорів та шумових ефектів (М. Мимрик).

Abstract: A bakery that produces and sells pastries is called Rini Cake Cookies Bakery in Pulo Bandring District. Gedangan Village is home to Rini Cake Cookies Bakery, Pulo Bandring District. The Rini Bakery processes a large number of sales transactions each day, which has an impact on the raw material inventory of the Rini Cake Cookies Bakery. Maintaining raw material stock levels requires you to keep just enough inventory on hand for sales while cutting down on expenses and labor. An organization's attempt to minimize risk and maximize sales is known as inventory control. The challenge facing the Rini Bakery is figuring out how much raw material stock needs to be produced in the upcoming month to keep up with customer demand, avoid buildup over an extended period of time, and preserve raw material stock stability. Because an accumulation of stock may cause the product to expire before it is given to buyers. Customer demand is the reason for this, as it varies each month based on prevailing patterns. A sales strategy is actually required in light of the current issues, and one such strategy is the use of a model, namely the Single Exponential Smoothing (SES) method, to anticipate or predict sales.Keywords: single exponential smoothing (ses) method; stock bread raw materials; web-basedAbstrak: Usaha yang memproduksi dan menjual kue kering adalah Rini Cake Cookies Bakery di Kecamatan Pulo Bandring.

Published: January 2025

Cascas, sementes e outras partes não comestíveis de frutas são resíduos frequentemente descartados durante o consumo e processamento, devido à falta de informação sobre a sua importância. Esses resíduos contêm consideráveis quantidades de nutrientes essenciais, e o seu aproveitamento pode trazer beneficios à saúde, além de contribuir para a redução de problemas ambientais e económicos. Desde a década de 70, diversas alternativas têm sido identificadas com o objectivo de aumentar o aproveitamento desses resíduos, seja como matéria-prima para a produção de alimentos ou como ingredientes passíveis de serem incorporados na alimentação. O presente estudo teve como objectivo avaliar a composição nutricional, mineral e identificar metabólitos secundários das cascas de canhú (Sclerocarya birrea). As cascas foram aproveitadas após a produção artesanal do sumo, higienizadas, secas naturalmente no laboratório por 336 horas com ventilação e secas em estufa com circulação do ar a 65o C por 72 horas. As amostras passaram por trituração em processador e crivagem para a obtenção de partículas finas (farinha), seguidas de análises laboratoriais. Parâmetros como carbohidratos, fibra bruta, proteínas e minerais essenciais apresentaram teores consideráveis de impacto para a saúde e podem ser utilizados para formulação em outros alimentos.
Towards ecologically functional buildings
Authors:   , Hecht Katharina
Published: January 2025

Life on Earth depends on ecosystem services (ESs), but pollution and climate change threaten ecosystem functioning. This leads to loss of biodiversity, reduced production of ESs and a negative impact on human well-being. To counteract this, regenerative solutions are becoming increasingly important, especially in urban areas, which have significant environmental benefits. Cities consume more energy and resources than they generate. Therefore, it is necessary to integrate technologies such as solar panels and nature-based solutions, such as vertical green systems (VGSs) and green roofs, into building designs. However, these solutions are often not linked and underutilized. This dissertation focuses on developing regenerative and ecologically functional buildings by integrating ESs.
Learning from ecosystems
Ecosystems function as living systems that provide regulatory, maintenance, provisioning and cultural services. These processes must be mimicked in building designs to achieve optimal interaction between buildings and their environment. Chapter 3 identifies nine strategies that allow ecosystems to use exergy (available energy) efficiently. By implementing these strategies, buildings can generate more ESs and reduce their impact on ecosystems.
Quantifying ecosystem services
To measure the output of ESs in building designs, exergy analysis is essential. Currently, exergy analysis is mainly applied to engineering systems in buildings. However, nature-based designs, such as biomass and biological sensors, should be added. In practice, ESs as indicators of regeneration are more understandable and useful.
A case study in Singapore examined the ecological benefits of ESs. These systems improved biodiversity, especially in deep vegetation and near trees. They also contributed to temperature regulation by cooling buildings. Although natural cliffs performed better in biodiversity, VGSs offer practical benefits for urban environments. These results complement a database that supports policymakers in developing regenerative policies.
Improving ES frameworks
Chapter 5 reviews existing ES frameworks to facilitate regenerative design in buildings. This resulted in 59 services applicable to buildings. A new concept links ESs to building systems and consumption flows, allowing building professionals to identify the impact of buildings on ecosystems and take regenerative action.
Practice-based research
Interdisciplinary action research with building professionals showed that workshops increase knowledge and motivation about regeneration. Participants were inspired to promote sustainability in their organizations. As a result, ESs were integrated into ambition plans for buildings and the environment.
Conclusion
The thesis highlights the need to integrate ecological processes into buildings for a more sustainable future. By implementing nature-based strategies and quantification methods, buildings can become regenerative and resilient, with a positive impact on both people and the environment.
Heart Perfusion for Tailored Preservation and Regeneration
Authors:   , Kaffka genaamd Dengler Selma Elisabeth
Published: January 2025

End-stage heart failure occurs in 1-10% of cases of heart failure. There are two treatment options: mechanical support and heart transplantation. Both treatments have advantages and disadvantages. Heart transplantation is the gold standard but is limited by the availability of suitable donor hearts. This dissertation describes the potential added value of donor hearts after circulatory death in the Netherlands. In addition, restarting the central circulation in the donor (thoraco-abdominal normothermic regional perfusion) may have advantages over removing the heart directly and supplying it with blood and oxygen on a machine. The ethical dilemmas surrounding this technique are highlighted. Given the scarcity, making optimal use of available donor hearts is of great importance. To gain a better understanding of the development of primary graft failure after transplantation, the risk factors for primary graft failure have been investigated. Despite the expected increase in available donor hearts due to the use of donor hearts after circulatory death, it is expected that alternative treatment methods will be necessary to treat a larger group of patients with end-stage heart failure. The "Cardiovascular moonshot" aims to regenerate the heart outside the human body. As part of the "Cardiovascular moonshot", this thesis describes the establishment of a model to use machine perfusion of the heart for the application of alternative treatment methods.
CRYSTAL STRUCTURES AND SPECTROSCOPIC CHARACTERISTICS OF COMPLEXES OF LANTHANOIDES WITH AMINOCARBOXYPHOSPHONIC ACIDS (review)
Authors: Trunova Olena
Published: January 2025

The review is devoted to a new class of com­plexones – aminocarboxyphosphonic acids and lanthanide metal complexes based on them. Interest in such compounds is due to the specificity of the structure of aminocarboxyphosphonic acids molecules, which contain various functional acid groups (carboxylic and phosphonic) at one main nitrogen atom, which differ significantly in basicity, charge, stereochemistry and size. This provides a wide range of coordination possibilities of ligands, which most fully satisfy the spatial requirements of the complexing ion and allows obtaining polynuclear structures of an unusual structure in the crystalline state. The article summarizes the literature data obtained by various authors regarding the study of the structure and spectral properties of aminocarboxyphosphonates of 4-f metals in solutions and crystals, their thermal properties, structural features, prospects for creating multifunctional technical materials based on them are considered.

Published: January 2025

A series of porphyrin containing polymer materials of various structure was developed. Free 5-(p-aminophenyl)-10,15,20-triphenylporphyrinand its ytterbium derivative were used to prepare materials of different structure and they were obtained by different approaches.Thus, two polymers were used in this study – the poly(methyl methacrylate) (PMMA), polystyrene (PS) as well as their copolymers of different composition (the molar ratio of 0.25/0.75, 0.5/0.5 and 0.75/0.25). Also part of materials were obtained by coprecipitation of polymer(s) with corresponding porphyrin derivative. The latter material ismore transparent, which allows obtaining an absorption spectrum with good resolution. All materials have notable emission characteristics – they emit in visible or near infrared (IR) range. Increasing of PMMA content in the final material causes the increase of fluorescence quantum yield for bothcopolymers and coprecipitatedmaterials.It can be explained by a higher light transmission coefficient of PMMA compared to PS.It was found out that 4f-luminescence in ytterbium-containing materialsdoes not depend on the type of polymer matrix and the variability of its compositionin contrast to fluorescence in the visible range.Almost 100% transparency of the studied polymers in the area of ytterbium ion radiation (980 nm)explains this phenomenon. It was also shown that obtainedmaterialsarestablefora long period of time and they keep the permanence oftheir emission parameters.This phenomenon can be explained by the extraordinary stability of PMMA even to UV radiation and by the high stability of porphyrin molecules. The use of a low concentration (0.1%) of lanthanide-porphyrin in the final material allows the IR emission efficiency of the Yb(III) ion to remain at the same level as in the corresponding methanol solution.

Published: January 2025

Complex tetrafluoroborates of Ni (II) with nitrogen-containing organic bases o-, m- and p-phenylenediamines (L) were synthesized. The composition and structure of the synthesized compounds were determined using a number of physico-chemical research me­thods. It was established that complexes of the general formula [NiL4](BF4)2 are formed for m- and p-isomers regardless of the synthesis conditions. In the case of o-PDA synthesis without a solvent at a 1:2 ratio of components gave the complex [Ni(o-PDA)2](BF4)2. The use of a solvent led to the formation of a ge­teroligand complex [Ni(o-PDA)2(H2O)2](BF4)2 due to the inclusion of two water molecules in the coordination sphere. The coordination centers of organic ligands and the nature of binding of the BF4- group were determined by IR spectroscopy. In the IR spectra of complex tetrafluoroborates the shift values of the νas(NH) bands in the low-frequency region indicate the formation of a metal-nitrogen coordination bond. The change in absorption bands of o-FDA in the IR spectra of the corresponding complexes corresponds to the bidentate character of this ligand. The nature of the absorption bands of valence and deformation vibrations of the tetrafluoroborate ion in compounds with m- and p-phenylenediamines and [Ni(o-PDA)2(H2O)2](BF4)2 indicates the preservation of the symmetry type of Td anion and its outer-sphere coordination. In the [Ni(o-PDA)2](BF4)2 spectrum the vibrational characteristics of the tetrafluoro­borate ion indicate the "semi-coordination" of the tetrafluoroborate ion. Based on the diffuse reflectance spectra analysis and the data of magnetic susceptibility measurements the octahedral structure of the coordination polyhedron for [Ni(o-PDA)2(H2O)2](BF4)2 and tetrahedral for compounds with m- and p-PDA was established. The [Ni(o-PDA)2](BF4)2 complex has a squareplanar structure. The results of the conducted investigation confirm the previously obtained dependence of the composition and structure of complex tetrafluoroborates on the electron-donor ability of organic ligands.

It was established that in the Pd(II)-edtmp and Pd(II)-pendtmp systems at a metal-ligand ratio of 1:1, complexes of equimolar composition [Pd(H4L1,2)Cl2]4-, [Pd(H3L1,2)Cl]4-, [Pd(H2L1,2)Cl]5-, [Pd(HL1,2)Cl]6-, and [Pd(L1,2)Cl]7- are formed, for which formation constants were calculated, and distribution diagrams of equilibrium concentrations were constructed as a function of solution pH. A bidentate mode of coordination of edtmp and pendtmp to the central metal ion by the nitrogen and oxygen atoms of the phosphonate group in the [Pd(H4L1,2)Cl2]4- complex and a tridentate mode by a nitrogen atom and two oxygen atoms of two phosphonate groups of one aminodi(me­thylphosphonate) moiety of ligands in complexes of the compositions [Pd(H3L1,2)Cl]4-, [Pd(H2L1,2)Cl]5-,[Pd(HL1,2)Cl]6-, and [Pd(L1,2)Cl]7- were determined. At the concentration ratio Pd(II)-edtmp=2:1 at pH>3, sparingly soluble hydrolysis products were formed in solutions, indicating the absence of inte­raction between the non-coordinated aminodi(methylphosphonate) moiety of the ligand and Pd(II) to form a binuclear complex. In contrast to edtmp, the system K2[PdCl4]-pendtmp at a 2:1 ratio exhibited the formation of binuclear complexes [Pd2(H3L2)Cl4]5-, [Pd2(H2L2)Cl2]4-, [Pd2(HL2)Cl2]5-, and [Pd2(L2)Cl2]6-. In the [Pd2(H3L2)Cl4]5- complex, two aminodi(methylphosphonate) moieties of pendtmp are coordinated to two Pd(II) ions in a bidentate mode by nitrogen and oxygen atoms of the phosphonate group, and in the complexes [Pd2(H2L2)Cl2]4-, [Pd2(HL2)Cl2]5-, and [Pd2(L2)Cl2]6-, they are coordinated in a tridentate mode by a nitrogen atom and two oxygen atoms of two phosphonate groups.

El presente trabajo evaluó el comportamiento agronómico de dos variedades de banano (Musa acuminata) en la finca Musatec, ubicada en San Rafael, Provincia de Santa Elena. El estudio abarcó variables como diámetro del pseudotallo, altura de la planta, número de hojas, peso del racimo, peso del raquis, número de manos y número de dedos por racimo, con el fin de identificar cuál de las dos variedades presenta un mejor rendimiento agronómico bajo condiciones de manejo orgánico. Los resultados muestran que la variedad Williams superó consistentemente a Formosana en todas las variables evaluadas. Específicamente, Williams presentó un mayor diámetro del pseudotallo (66.23 cm vs. 58.38 cm), altura de planta (3.05 m vs. 2.57 m), número de hojas (7.55 vs. 6.82), peso del racimo (23.32 kg vs. 19.53 kg), peso del raquis (4.19 kg vs. 3.15 kg), número de manos (7.68 vs. 6.76), y número de dedos por racimo (118.18 vs. 98.73). El análisis estadístico-descriptivo, realizado mediante una prueba de T para observaciones pareadas, confirmó que las diferencias observadas son significativas, indicando que la variedad Williams tiene un mejor comportamiento agronómico bajo las condiciones de estudio. Este hallazgo sugiere que Williams podría ser más adecuada para maximizar la productividad en sistemas de manejo orgánico en la región.

Las células dendríticas, fundamentales en la respuesta inmune al presentar antígenos a los linfocitos T y B, pueden desarrollar neoplasias extremadamente raras, representando menos del 1% de los tumores de origen ganglionar. Presentamos un caso de sarcoma de células dendríticas interdigitantes que, tratado con quimioterapia, mostró una evolución favorable y un buen pronóstico. Debido a la rareza de esta enfermedad, es crucial considerarla en diagnósticos diferenciales, ya que la supervivencia del paciente depende del estadio en el que se detecte.

Aims

The objective of this study is to illustrate the application of a machine learning algorithm, K Nearest Neighbor (k-NN) to impute missing alcohol data in a prospective study among pregnant women.

Methods

We used data from the Safe Passage study (n = 11,083). Daily alcohol consumption for the last reported drinking day and 30 days prior was recorded using the Timeline Follow back method, which generated a variable amount of missing data per participants. Of the 3.2 million person-days of observation, data were missing for 0.36 million (11.4%). Using the k-NN imputed values were weighted for the distances and matched for the day of the week. Since participants with no missing days were not comparable to those with missing data, segments of non-missing data from all participants were included as a reference. Validation was done after randomly deleting data for 5–15 consecutive days from the first trimester.

Results

We found that data from 5 nearest neighbors (i.e., K = 5) and segments of 55 days provided imputed values with least imputation error. After deleting data segments from the first trimester data set with no missing days, there was no difference between actual and predicted values for 64% of deleted segments. For 31% of the segments, imputed data were within +/−1 drink/day of the actual. Imputation accuracy varied by study site because of the differences in the magnitude of drinking and proportion of missing data.

Conclusion

k-NN can be used to impute missing data from longitudinal studies of alcohol during pregnancy with high accuracy.

Understanding the impact of light on, and how it is perceived by, farm animals is crucial for the design of appropriate, high-welfare housing and management conditions. By considering the animal’s visual needs and adaptive capabilities, future housing and management can allow them to better express their natural behavior. In the past, animal environments have been designed primarily to optimize production output and adjusted to human needs. This emphasis has changed toward a more animal-based focus. However, especially in farmed ungulates, there is still limited knowledge about the impact of light parameters on their physiology, performance, and behavior. This poses the risk of not appropriately assessing the importance of these abilities when the animals interact with their physical environment. Here, we provide an overview of the current state of research on the impact of light parameters on farmed ungulates and their preferences for light settings in the most common farmed ungulate species: pigs, sheep, goats, cattle and horses. We focus on three specific light parameters: photoperiod, illumination, and color. Secondly, we identify gaps of knowledge and emphasize their implications for animal welfare and potential improvement of current animal husbandry environments. There was considerable variation in the number of studies by species and light parameters. A large focus of studies looked at illumination in pigs and color perception in horses. Research on cattle, sheep and goats, seems to be underrepresented in the literature. From a human perspective, we tend to overestimate the importance of color perception and preference, whereas contrast discrimination in combination with illumination intensity and quality seems to be more relevant for ungulate orientation and interaction with their environment. Aside from the importance of other senses and their interaction with vision, we conclude that illumination and photoperiodicity seem to be most relevant for securing the welfare of farm ungulates. These aspects should therefore be given more consideration in indoor housing improvements. Future research emphasis should be given to preference testing studies, as they provide insights into the animals’ motivation for specific light conditions that may further improve their welfare, but also health and performance.

The impact of corn silage supplementation and post mortem aging on the antioxidant status in longissimus thoracis et lumborum (LTL) muscle was assessed using micro-spectroscopic techniques. A total of 30 Braford steers were utilized in the study. Of these, 15 animals were supplemented with corn silage for 120 days, while the remaining animals were fed exclusively on pasture. LTL steak samples were aged for 2, 7, 14, and 21 days at a temperature of 2 ± 1°C, under conditions of darkness and vacuum. Several colorimetric assays were employed to evaluate the antioxidant capacity of both enzymatic and non-enzymatic origin, as well as the levels of protein and lipid oxidation. The content of heme pigment was determined by a spectrophotometric assay, while the fluorescence fingerprint of beef was evaluated by fluorescence spectroscopy excitation-emission matrices (FEEM). Additionally, the muscle microstructure was analyzed via scanning electron microscopy (SEM). The results demonstrated that the finishing system did not exert any discernible influence on the rates of lipid oxidation, antioxidant capacity, or muscle microstructure. However, the carbonyl content and total myoglobin exhibited higher levels in the corn silage-supplemented animals. Conversely, during aging period, data revealed that lipid degradation proceeded at a faster rate than protein oxidation, accompanied by a notable enhancement in antioxidant capacity within the hydrophilic meat extracts. In contrast, the lipophilic extracts demonstrated a reduction in both enzymatic and non-enzymatic antioxidant capabilities with the progression of post mortem aging. The aforementioned alterations were accompanied by a reduction in the muscle microstructure during the aging process. The results demonstrate that finishing steers with or without corn silage over 120 days results in comparable and satisfactory beef quality after 21 days of vacuum aging. It can be concluded that 21 days of storage compensates the antioxidant status obtained by feeding strategies in fresh meat. Furthermore, SEM and FEEM techniques allowed for a precise evaluation of the microstructure and oxidative status, suggesting that these methods could be employed in future assays.
