String quartet ,classical music ,violin ,viola ,cello - Abstract
Composed in 2020, this string quartet is fun and playful, for both the performers and audience to enjoy. Romp! is meant to get people's feet tapping and be a happy distraction. In rondo form, Romp! opens with a jaunty melody in the first violin. This rondo theme is interspersed with a wistful waltz, and then later with a hoe-down, and American-West inspired dance. String effects include glissandi and the cello being strummed as a guitar.The melodies are all original, and are supported by various harmonic structures to give the piece edge and vitality. Romp! builds in momentum to a rousing finish.

CONTROLLED atmosphere packaging , *COLD storage , *MALIC acid , *VIOLA , *FLOWERS - Abstract
Edible flowers are becoming increasingly popular as food products, since they give aroma, color, and visual appeal and are also health-promoting compounds. However, they are a highly perishable product, thus post-harvest technologies are needed to extend their marketability. In this study, active (N2: 100%) and passive modified atmosphere packaging (MAP) technologies were applied to three edible flower species, namely Begonia grandiflora 'Viking', Tropaeolum majus, and Viola cornuta, stored at 4 °C. Even if the flowers' quality decay occurred differently according to the species, active MAP better maintained petal colors and slowed down the edible flowers' decay than passive MAP by decreasing flower respiration in all three species and sugars consumption in begonia; there was weight loss in nasturtium, and better preserved total phenolic content in begonia and viola. Coupling cold storage with active MAP can be an effective method to extend edible flowers' post-harvest life. [ABSTRACT FROM AUTHOR]

Violafuscopurpurea (Violaceae), a new species from Karst landform of Chongqing in China, is described and illustrated. The new species is most similar to V. fukienensis, but can be distinguished by nearly glabrous, shiny, adaxially purple blades (vs pubescent, adaxially green blades), brown seeds with conspicuous tubercles (versus yellow seeds with smooth surface), and hook‐like nectaries (versus triangular nectaries), as well as by general habit. Our phylogenetic analysis, based on ITS sequences, confirms that the new species belongs to V. subsect. Rostratae, and is most closely related to V. fukienensis in the phylogeny.

Glioblastoma (GBM) is the most aggressive cancer originating in the brain, but unfortunately combination treatments with resection, radiation, and chemotherapy are relatively ineffective. Therefore, novel methods of adjuvant therapy are critically needed. Cyclotides are plant-derived circular peptides that chemosensitize drug-resistant breast cancer to doxorubicin. We analyzed naturally occurring and synthetic cyclotides (Cycloviolacin O3, Cycloviolacin O19, natural Kalata B1, synthetic Kalata B1, and Vitri E) alone and in co-exposure treatments with the drug temozolomide (TMZ) in human glioblastoma cells. The cyclotides were identified by UPLC-PDA and HPLC-UV. The synthetic Kalata B1 sequence was verified with orbitrap LC-MS, and structural confirmation was provided by NMR spectroscopy. The cyclotides displayed dose-dependent cytotoxicity (IC
50 values 2.4–21.1 µM) both alone and as chemosensitizers of U-87 MG and T 98 cells to TMZ. In fact, a 16-fold lower concentration of TMZ (100 µM) was needed for significant cytotoxicity in U-87 MG cells co-exposed to synthetic Kalata B (0.5 µM). Similarly, a 15-fold lower concentration of TMZ (75 µM) was required for a significant reduction in cell viability in T 98 cells co-exposed to synthetic Kalata B1 (0.25 µM). Kalata B1 remained stable in human serum stability assays. The data support the assertion that cyclotides may chemosensitize glioblastoma cells to TMZ. [ABSTRACT FROM AUTHOR]- Published

CYCLIC peptides , *DRUG discovery , *SMALL molecules , *VIOLA , *MASS spectrometry - Abstract
Cyclotides are plant cyclic peptides with exceptional stability and diverse bioactivity, making them promising candidates for biomedical applications. Therefore, the study of cyclotides has attracted increasing attention in recent years. However, the existing cyclotide detection methods face limitations in sensitivity, accuracy, and reliability. To address these challenges, we developed an integrated strategy using a combination of strong cation exchange chromatography techniques for removing interfering small molecules, Orbitrap Exploris 480 mass spectrometry (OEMS); this is a detection and database searching-based method for cyclotide verification, which greatly improved the sensitivity, accuracy, and reliability of cyclotide identification. This strategy was subsequently employed for cyclotide mapping in Viola with a minute amount of starting tissue, resulting the identification of 65 known and 18 potentially novel cyclotides, which is the largest dataset of cyclotides for Viola philippica. This strategy provided valuable insights into the cyclotide diversity and distribution in V. philippica, with potential applications in drug discovery and other biomedical fields.

Abstract The Violaceae family is rich in metal-tolerant species and species producing cyclic peptides (cyclotides) that are linked to the resistance to biotic factors. Plants that inhabit areas polluted with heavy metals have developed various mechanisms of tolerance. To test the role of cyclotides in protection against abiotic factors, including heavy metals, cell suspension cultures of Viola species/genotypes (V. lutea ssp. westfalica, V. tricolor, V. arvensis, and V. uliginosa), representing different levels of tolerance to heavy metals (from the most tolerant-MET to the least tolerant populations/species-NMET), were used. The relative abundances of the cyclotides in the control, untreated cell suspensions of all the selected species/genotypes, and cells treated with Zn or Pb (200 µM or 2000 µM) for 24 h or 72 h were determined via MALDI-MS. Transmission electron microscopy with X-ray microanalysis was used to detect putative co-localization of the cyclotides with Zn or Pb in the cells of V. tricolor treated with the highest concentration of heavy metals for 72 h. Cyclotide biosynthesis was dependent on the type of heavy metal and its concentration, time of treatment, plant species, and population type (MET vs. NMET). It was positively correlated with the level of tolerance of particular Viola species. The increased production of cyclotides was observed in the cells of metallophyte species, mostly in Zn-treated cells. The nonmetallophyte—V. uliginosa presented a decrease in the production of cyclotides independent of the dose and duration of the metal treatment. Cyclotides co-localized with Pb more evidently than with Zn, suggesting that cyclotides have heavy metal affinity. V. lutea ssp. westfalica transcriptome mining yielded 100 cyclotide sequences, 16 known and 84 novel named viwe 1–84. These findings support the hypothesis that cyclotides are involved in certain mechanisms of plant tolerance to heavy metals.

Abstract In the present work, the inhibition performance of Viola extract based on bulk and nano size as a green corrosion inhibitor on mild steel in 0.5 M phosphoric acid and 1M hydrochloric acid solutions is investigated using different techniques (potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and Optical microscopy). The gained results demonstrated that various concentrations of Viola Extract (bulk and nano) inhibited the corrosion of the alloy in both of the acid solutions. The temperature impact on corrosion rate without/with this extract was examined. Certain thermodynamic parameters were determined based on the temperature impact on inhibition and corrosion processes. The adsorption mechanism of the extract on the alloy was explored using the Langmuir adsorption isotherm. A mixed mode of adsorption was observed, wherein the nano-sized extract in 1.0 M HCl predominantly underwent chemisorption, while the bulk-sized extract in 1.0 M HCl and both bulk and nano-sized extracts in 0.5 M H3PO4 were primarily subjected to physisorption. Scanning electron microscopy (SEM) and Optical microscopy analyses were employed to scrutinize alloys’ surface morphology.

For a size parameter s : ℕ → ℕ , the Minimum Circuit Size Problem (denoted by MCSP[s(n)]) is the problem of deciding whether the minimum circuit size of a given function f : {0,1}n →{0,1} (represented by a string of length N := 2n) is at most a threshold s(n). A recent line of work exhibited "hardness magnification" phenomena for MCSP: A very weak lower bound for MCSP implies a breakthrough result in complexity theory. For example, McKay, Murray, and Williams (STOC 2019) implicitly showed that, for some constant μ1 > 0, if MCSP [ 2 μ 1 ⋅ n ] cannot be computed by a one-tape Turing machine (with an additional one-way read-only input tape) running in time N1.01, then P≠NP. In this paper, we present the following new lower bounds against one-tape Turing machines and branching programs: (1) A randomized two-sided error one-tape Turing machine (with an additional one-way read-only input tape) cannot compute MCSP [ 2 μ 2 ⋅ n ] in time N1.99, for some constant μ2 > μ1. (2) A non-deterministic (or parity) branching program of size o (N 1.5 / log N) cannot compute MKTP, which is a time-bounded Kolmogorov complexity analogue of MCSP. This is shown by directly applying the Nečiporuk method to MKTP, which previously appeared to be difficult. (3) The size of any non-deterministic, co-non-deterministic, or parity branching program computing MCSP is at least N 1.5 − o 1 . These results are the first non-trivial lower bounds for MCSP and MKTP against one-tape Turing machines and non-deterministic branching programs, and essentially match the best-known lower bounds for any explicit functions against these computational models. The first result is based on recent constructions of pseudorandom generators for read-once oblivious branching programs (ROBPs) and combinatorial rectangles (Forbes and Kelley, FOCS 2018; Viola, Electron. Colloq. Comput. Complexity (ECCC) 26, 51, 2019). En route, we obtain several related results: (1) There exists a (local) hitting set generator with seed length O ~ (N) secure against read-once polynomial-size non-deterministic branching programs on N-bit inputs. (2) Any read-once co-non-deterministic branching program computing MCSP must have size at least 2 Ω ~ (N) . [ABSTRACT FROM AUTHOR]

This is a study on the microtonal aspects of György Ligeti's Hamburgisches Konzert für Horn und Kammerorchester mit 4 obligaten Naturhörnern, with special reference to its relationship with the American composer Harry Partch. The special mixture of equal temperament versus just intonation is analyzed for longer passages and adhoc chords in the concept of Ligeti. The movement "Choral" is confronted with Harry Partch's idea of "tonality flux". The "Hamburgisches Konzert für Horn und Kammerorchester mit 4 obligaten Naturhörnern" by György Ligeti, composed in 1998-20022, joins a long chain of exploratory forms of thought in his compositional work long years before he had pondered meloharmonics that would illuminate the great theme of tonality in a novel, personal way. In the Horn Trio (1982), melodies containing natural tones appear for the first time in the movement "Alla Marcia." Previously, in the same work, Ligeti used the 11th harmonic as a precise quarter tone. Yet in the Horn Trio, these microtonal events are transverse to the other voices of violin and piano. Ligeti spoke of three "autists," each living in his world of moods/tunings. In the works that followed, microtones take up an ever wider space, up to the Piano Concerto (1985-88) with 5th, 7th or 11th harmonics in trumpet, horn and trombone, and then to the Violin Concerto (1990-92), where two solo satellite strings from the orchestra, violin and viola, are retuned in natural interval relationships. The Viola Solo Sonata (1991-94) contains in the first movement "Hora lungă" a sign world new to Ligeti for natural thirds, natural sevenths and the 11th natural tone. He adopts these signs for the Hamburgisches Konzert, on which we will now focus. [ABSTRACT FROM AUTHOR]

Violets (Viola) are potential candidates for aroma-focused breeding research. Though most Viola species and modern hybrids lack fragrance, the genus contains a famously scented species, Viola odorata L. This species and its cultivars are genetic resources of aroma traits that could be used to investigate the selection for and transmission of fragrance during the breeding process. Despite its famous scent, however, the floral volatile emissions of V. odorata have not been characterized using modern headspace techniques. Using static and dynamic headspace volatile collection methods and gas chromatography-mass spectrometry, the floral volatile emissions of V. odorata were temporally and developmentally characterized. Floral volatiles were also sampled from 10 V. odorata cultivars, three Parma violet cultivars, five violet species, and one hybrid, and variation in scent among these violets was investigated. Total volatile emissions in V. odorata were highest from 0600 HR to 1900 HR, suggesting a diurnal pattern of emission. Volatile emissions also varied over the developmental lifespan of the flower, with the highest emission of individual and total volatiles occurring, in general, from stages 0 or +1 to stages +3 or +4. Floral scent qualitatively and quantitatively differed among assorted violets. The floral volatile emissions of V. odorata exhibit temporal and developmental variation. Compared with the other violet species in this study, sweet violets are intensely fragrant. The quantity and quality of floral scent differs among V. odorata cultivars, providing genetic variation from which selections could be made in a fragrance-focused breeding program.

Viola dalatensis, belonging to the Violaceae family, is an endemic species to Vietnam. The present study aimed to determine phenolic compounds in extracts from aerial parts of the plant species using high performance liquid chromatography with diode-array detection (HPLC-DAD). In addition, free radical scavenging and bovine albumin denaturation inhibition assays were performed to evaluate the antioxidant and in vitro anti-inflammatory activities of the extracts. Most of the phenolic compounds in the methanolic extract were detected at the greatest concentrations compared to the other extracts, which was also supported by the highest total phenolic content (26.70 ± 0.1059 mg GAE/g). In general, the antioxidant activities of the methanolic and ethanolic extracts were found to be stronger than those of the other extracts. The aqueous extract exhibited the most potent inhibitory effect on albumin denaturation (IC50 = 90.39 ± 8.415 µg/mL), comparable with that of diclofenac. Through principal component analysis, 88.60% of the total variance in the phenolic dataset was explained. The correlation analysis showed that chlorogenic acid, ferulic acid, epigallocatechin gallate, rutin, and kaempferol may play important roles in antioxidant activity while gallic acid could contribute to in vitro anti-inflammatory activity of the extracts. The findings of this study provide the first evidence of the bioactive compounds present in V. dalatensis and shed light on the potential health-promoting properties linked to its aerial parts.

Rebecca Clarke, who was an active viola performer during her lifetime and had an extremely brilliant career, also took her place in history as one of the main composers of the 20th century British music school. Although she faced difficulties as a female composer and most of her works were published almost close to the present day, she made a significant contribution to the development of the viola repertoire, which had limited works at that time, with the viola works she wrote. Written by Rebecca Clarke in one movement and named after Morpheus, the God of Dreams in Greek mythology, and revealing the impressionist style of the composer, the work perfectly synthesizes all the features of the technical and musical dominance of the viola and is frequently performed in concerts as it has an important place in the repertoire of today's viola performers. In this study, the events in Rebecca Clarke’s life that influenced her creativity and the composition style that developed after them were discussed, and it was aimed to make the composer's musical style and "Morpheus" known by examining it and to contribute to a more conscious interpretation of violists who want to perform the work in Turkey.

Purpose: Alternative and affordable tick control strategies are crucial to control and prevent tick bites and tick-borne diseases. Methods: In this study, we evaluated the acaricidal efficacy of 35 aqueous plant extracts (17%) against the camel tick, Hyalomma dromedarii. Results: The phytochemical profile indicated the presence of various secondary substances. Plants were classified into three groups according to their mortality percentage 15 days post-treatment with 17%. This highly effective group (91%–95%) comprised Ocimum basilicum, Mespilus germanica, and Viola alpine followed by Carum carvi, Cucurbita pepo (peel), and Peganum harmala. A moderately effective group (80%–90%) included Acacia nilotica, Apium graveolens, Capsicum annuum, Ceratonia siliqua, Cucurbita pepo (seeds), Equisetum arvense, Eruca sativa, Ginkgo biloba, Plantago psyllium, Phyllanthus emblica, Punica granatum, and Ziziphus spinachristi. The 20 remaining plants were assigned to the less effective group (< 80%). Viscum album (58.3%), which was the least effective reference plant. The high potency of six plant extracts as acaricides may be attributed to the high content of active principles, e.g., phenols, flavonoids, and tannins. Conclusion: All of these highly effective plants are recommended for use as an acaricide, in case of facing acaricidal resistance or limited options for tick control. [ABSTRACT FROM AUTHOR]

Purposely, the main focus of this research was to analyze the feasibility of investment value on Cluster Bukit Viola Citra Indah City housing development project. Housing development projects play a key role in the economic development of every society and country. According to the European Commission (2005), housing has an important role in the economic development of every country and it makes 10%-20% of economic development. The request for housing in economic will respond through a concept of purchaser act, it means that consumers would consider in buying a house subjected to the usefulness of the house. In other words, the business person needs to conduct marketing policy and implementation with its maximum usefulness in the opinion of the consumer, (Chantuk, T., Kulsawat, T., & Klangburam, N. 2013). The main objective of this study was to determine the total cost, feasibility and infeasibility and the total profit can be obtained from this Project. For analyzing the investment value of this housing project, and to determine the level of feasibility of the project we used Net Percent Value (NPV) and Benefit Cash Ratio (BCR indicators. In this study, we used Microsoft excel to analyze the data. Through the calculation and data analysis, the result of NPV and BCR with 20%, 25% and 30% profits have different results. With 20% profit the outcome of NPV 5.337.773.360,935 and greater than 0 and the outcome of PCR is 1.4 greater than 1 so, the project is feasible, with 25% the outcome of NPV is 11.119.394.451,093 greater than 0 and the outcome PCR is 1,09 greater than 1 so, the project is feasible and with 30% profits the outcome of NPV is Rp 16.901.015.541,250 greater than 0 and then outcome of PCR is 1,13 greater than 1 and the project is feasible to run. Among these three analyses is the best choices is 25 % because this is the optimum condition that the project can run safely. [ABSTRACT FROM AUTHOR]

We investigated the paraglacial evolution and permafrost degradation of Val Viola (Upper Valtellina, Central Italian Alps) through a geomorphologic survey, cosmogenic dating, Schmidt's Hammer, and surface roughness measurements. Our results reveal that the previously mapped Val Viola rock avalanche is probably derived by three different events that occurred 7.7 ± 0.2 ka (Orthogneiss_ 1), 7.0 ± 0.2 ka (Paragneiss), and 5.0 ± 0.3 ka (Orthogneiss_2). Because the main valley bottom has been ice free since at least 12.6 ka, it is unlikely that the triggering factor of these events was the debutressing stress caused by the melting of local valley glaciers. Therefore, permafrost that formed in this area down to 2525 m a.s.l. at 9.3–8 ka and degraded successively between 7.8 and 6.5 ka was likely the main triggering factor of the first two rock avalanche events, as well as for the third event that happened during the warm and wet period of the Holocene Thermal Maximum around 5 ka.

Cyclotides are a type of defense peptide most commonly found in the Violaceae family of plants, exhibiting various biological activities. In this study, we focused on the Viola japonica as our research subject and conducted transcriptome sequencing and analysis using high-throughput transcriptomics techniques. During this process, we identified 61 cyclotides, among which 25 were previously documented, while the remaining 36 were designated as vija 1 to vija 36. Mass spectrometry detection showed that 21 putative cyclotides were found in the extract of V. japonica. Through isolation, purification and tandem mass spectrometry, we characterized and investigated the activities of five cyclotides. Our results demonstrated inhibitory effects of these cyclotides on the growth of Acinetobacter baumannii and Bacillus subtilis, with minimum inhibitory concentrations (MICs) of 4.2 μM and 2.1 μM, respectively. Furthermore, time killing kinetic assays revealed that cyclotides at concentration of 4 MICs achieved completely bactericidal effects within 2 h. Additionally, fluorescence staining experiments confirmed that cyclotides disrupt microbial membranes. Moreover, cytotoxicity studies showed that cyclotides possess cytotoxic effects, with IC50 values ranging from 0.1 to 3.5 μM. In summary, the discovery of new cyclotide sequences enhances our understanding of peptide diversity and the exploration of their activity lays the foundation for a deeper investigation into the mechanisms of action of cyclotides.

The present Porcine circovirus type 2 virus (PCV 2) vaccine adjuvants suffer from numerous limitations, such as adverse effects, deficient cell-mediated immune responses, and inadequate antibody production. In this study, we explored the potential of a novel nanoparticle (CS-Au NPs) based on gold nanoparticles (Au NPs) and chitosan (CS) that modified Viola philippica polysaccharide (VPP) as efficient adjuvants for PCV 2 vaccine. The characterization demonstrated that CS-Au-VPP NPs had a mean particle size of 507.42 nm and a zeta potential value of −21.93 mV. CS-Au-VPP NPs also exhibited good dispersion and a stable structure, which did not alter the polysaccharide properties. Additionally, the CS-Au-VPP NPs showed easy absorption and utilization by the organism. To investigate their immune-enhancing potential, mice were immunized with a mixture of CS-Au-VPP NPs and PCV 2 vaccine. The evaluation of relevant immunological indicators, including specific IgG antibodies and their subclasses, cytokines, and T cell subpopulations, confirmed their immune-boosting effects. The in vivo experiments revealed that the medium-dose CS-Au-VPP NPs significantly elevated the levels of specific IgG antibodies and their subclasses, cytokines, and T cell subpopulations in PCV 2 -immunized mice. These findings suggest that CS-Au-VPP NPs can serve as a promising vaccine adjuvant due to their stable structure and immunoenhancement capabilities. [ABSTRACT FROM AUTHOR]

Viola suavis var. pannonica (Violaceae) from central Europe is described here as a new variety to science. It is most similar to the blue-flowered V. suavis var. suavis and the white-flowered V. suavis var. catalonica and V. suavis subsp. naqshii, but exhibits differences in several characters, such as petal colour, spur shape, fimbriae length on the stipules, bracteoles position on the peduncle and lamina sinus shape. Although the new taxon is often considered a colour mutation of V. suavis var. suavis, previous genetic analyses revealed that these white-flowered plants do not arise recurrently at different locations (having multiple origins), but rather form a monophyletic evolutionary lineage. To date, the occurrence of V. suavis var. pannonica has been reported in the Slovak Republic, the Czech Republic and western Ukraine. In this paper, we report its occurrence in Austria and Hungary. Notes on its etymology, distribution, ecology, origin and hybridization, as well as photographs of the new variety (including the holotype) are also provided. [ABSTRACT FROM AUTHOR]

Morphological measurements and genetic analysis of Epitrimerus violarius Liro (Acariformes: Eriophyoidea) with illustrations of males, females, and immature stages are presented in this paper. This species was reported for the first time in Poland and was collected from the leaves of Viola uliginosa in Cracow. The findings of this research provide insights for reassignment from the genus Epitrimerus Nalepa to the genus Leipothrix Keifer, within the family Eriophyidae. Aside from the molecular analysis that confirms the association with the proposed genus, the reassignment is also supported by the absence of femoral seta (bv) on both pairs of legs, and the presence of bifurcate gnathosomal seta, which are unique for Leipothrix.

- Abstract
Self-regulation strategies and behaviors are important aspects of instrumental music learning because they allow students to set learning goals by testing and controlling their cognition, motivation, behaviors, and emotions. This work investigates the self-regulation processes of four young instrumentalists (aged 10–11 years) in their initial stages of viola and violin learning, during practice with Plectrus, a real-time instrumental intonation training and assessment software. The qualitative-hermeneutical nature of this research employed a multiple case study design to investigate the construct of self-regulation within a software-supported instrumental learning process. Data were collected from the participants' practice diaries over a 4-week period. The final practice session was also analyzed from audio-visual recordings. The results indicate that, despite their limited experience, the students showed a diversity of strategies and behaviors with which they self-regulated their cognitions, motivations, behaviors, and emotions. However, not all the students employed the same processes, and there was variability in the frequency of their use. One of the students showed more self-regulatory processes than the rest and achieved the best scores, although it has not been possible to establish a relationship between the scores and self-regulation.

Despite great potential for arbuscular mycorrhizal fungi (AMF) in restoration of heavy metals (HMs) polluted lands, limited information is available about the arbuscular mycorrhizal (AM) symbiosis of naturally-occurring hyperaccumulators. A preliminary survey was conducted to investigate the AM symbiosis of Viola baoshanensis, a Cadmium (Cd) hyperaccumulator, growing at an abandoned mine. Shoot/root ratios of 1.78 for Cd, and 2.57 for zinc (Zn) indicate that these two metals were preferentially transported from roots to shoots, whereas the ratio of 0.32 for lead (Pb) shows that most Pb was stored in roots. High level of colonization was found in the roots of V. baoshanensis with relative mycorrhizal root length of 69.1%, relative arbuscular richness of 46.9% and relative vesicular richness of 1.7%. Fifteen AMF species were identified from the root zone soil of V. baoshanensis. The dominant AMF genus was Glomus, and the most abundant species were Glomus ambisporum and Claroideglomus etunicatum.

- Abstract
The growing interest in functional foods is driven by the exploration of new foods with positive health effects. Pleasant sensory features are essential for consumer acceptance. In this work, we investigated the composition of the bioactive compounds, antioxidant activity, and aroma profiles of four edible flowers: Cucurbita moschata Duchesne, Dianthus chinensis L., Fuchsia regia (Vand. ex Vell.) Munz., and Viola cornuta L. For the first time, we quantified the water-soluble group of B vitamins. Significant variations in the content of soluble sugars, vitamins, and secondary metabolites were observed. V. cornuta showed the highest concentration of vitamin C and carotenoids, while C. moschata had the highest content of vitamin B and flavonoids. F. regia stood out for its exceptionally high content of total phenolics, while D. chinensis surpassed the other flowers in soluble sugar content. The aroma profile analysis revealed a diverse array of volatile organic compounds, with each species having its own unique composition. C. moschata was characterized by p-dimethoxybenzene and D. chinensis by non-terpene compounds; F. regia displayed high amounts of decanal and nonanal, while V. cornuta was rich in myrcene and α-farnesene. These findings provide valuable insights into the secondary metabolites and aroma profiles of these flowers, enhancing our understanding of their bioactive compounds and potential health benefits.

The two women authors Viola Fischerová (1935 - 2010) and Jaroslava Blažková (1933 - 2017) belong to the same generation, but to (seemingly?) different national literary traditions. The writers ceaselessly experience in their life and work the Central European literary and political space from which they originate. The reception of their writing - by general and professional readership - is ambiguous in both cases. Although critics often suggest that from the literary point of view, they are individually "emptied vessels" about which there is nothing more to say, contemporary perspectives and literary scholarly discussions suggest that a return to their poetics is relevant. On the basis of established literary theoretical premises and by means of parallel analysis and interpretation (which also underline distinct authenticity of their work), the paper attempts to outline those aspects of the texts that might stimulate a renewed interest in the personalities and poetics of these authors in a broader context. In this way, it tries to transcend the boundaries (literary-historical, interpretative, etc.) that have been created for various reasons. [ABSTRACT FROM AUTHOR]

Plant residues derived from the agro-industrial sector and their disposal are still unsolved issues despite the various research and applications. The current study assessed the possible peat substitution in growing media with solid residues derived from the distillation of Origanum dubium Boiss (OD) and Sideritis cypria Post (SC) after essential oils production. Residues of OD and SC (0–5–10–20% v/v) and their mixture (OD + SC) were examined to partially substitute peat for the production of pansy (Viola × wittrockiana) plants. The presence of OD, SC, and OD + SC residues increased the pH, the electrical conductivity, the organic matter content, and the levels of minerals in the growing media mixtures compared to sole peat while decreasing the total porosity (up to 36.8%) and the available free air (up to 58.3%). The OD residues' presence in the peat-based media revealed more detrimental effects than the SC, while the OD + SC mixture received intermediate effects. Low residue ratios (≤5% OD, ≤10% SC, ≤10% OD + SC) sustain plant growth and photosynthetic activity of plants, while higher ratios decrease plant growth, chlorophyll content and mineral accumulation due to inappropriate growing media properties, causing plant oxidative stress. This was verified using the increase in malondialdehyde (up to 4.5 times) and hydrogen peroxide (up to 2.1 times) content in plants and the activation of several non-enzymatic antioxidant processes, including total phenols, flavonoids, and antioxidant capacity of the plants. Therefore, OD, SC, and OD + SC at 5%, 10%, and 10%, respectively, can partially substitute peat, as they result in appropriate plant growth and development. However, the growing media's properties must be improved to ensure adequate yields as well. [ABSTRACT FROM AUTHOR]

Viola pendulipes (Violaceae), a new myrmecochous species from Baiwan Nature Reserve of Guangdong Province in China, is described and illustrated. Morphologically the new species is most similar to V. nanlingensis, but it is easily distinguished by having truncate or cuneate leaf base (versus cordate leaf base), robust rhizome with short internodes (versus slender rhizome with long internodes), curved and drooping peduncles in fruit (versus erect peduncles in fruit), and oblong anterior petals (versus spatulate to rhombic anterior petals). Our phylogenetic analysis, based on ITS sequences, confirms that the new species belongs to V. subsect. Diffusae, and is most closely related to V. yunnanensis. [ABSTRACT FROM AUTHOR]

The article focuses on the design of a 1796 viola made by Austrian lute and violin maker Sebastian Dalinger. The viola has narrow proportions with Staineresque f-holes. The front is made of spruce, while the back and ribs are made of maple. The arching of the viola is significantly lower than on Dalinger's earlier works, resulting in an increase in tonal brilliance that is said to indicate his awareness of the growing need for instruments fit for larger spaces.

Juan Crisóstomo de Arriaga compuso durante sus escasos veinte años de vida obras que escapan a lo común y aún no se han descifrado los orígenes del talento que le llevó a tales resultados. A través del cuarteto de cuerda, uno de los géneros que ha acompañado a Juan Crisóstomo en todas las etapas de su vida, el presente trabajo propone una vía alternativa a los estudios convencionales con la viola como elemento vehicular. Un análisis del balance de voces de sus cuartetos nos brindará información de las ideas transformistas de Arriaga en torno a este género y desmontará las principales hipótesis sobre su origen: la influencia de la escuela vienesa a través de la incidencia de Haydn en España y su posible replanteamiento del cuarteto de cuerda tras su etapa académica parisina. La existencia del Tema variado para cuarteto de cuerdas op.17, un cuarteto previo a su traslado a la capital francesa de construcción igualitaria y asignación de ciertas técnicas complejas a la viola, nos acerca un paso más hacia la comprensión de su forma de concebir la composición cuartetística y hasta qué punto excede a los estándares marcados por sus contemporáneos españoles, así como por sus referentes internacionales.

Viola odorata is a viola family flowering plant native to Europe and Asia. This is a small, hardy, herbaceous, perennial plant. It is also known as sweet violet and English violet. Numerous pharmacological properties of this flowering plant include anticancer, antibacterial, anti-inflammatory, antioxidant and antipyretic properties. Previous literature review of different parts of Viola odorata resulted in detection of different chemical constituents such as flavonoids (Quercetin, kaempferol), glycosides (Rutin) and terpenoids (stigma sterol). Stigmasterol was detected using TLC and GC-MS in this study. It was isolated from Viola odorata using preparative layer chromatography. HPLC and FTIR analysis confirmed the isolated Stigmasterol
