Solo lyra viol music of Tobias Hume (c. 1579-1645): Historical context and transcription for modern guitar.

The seventeenth century in England produced a large and historically significant body of music for the viola da gamba played "lyra-way." Broadly defined, playing "lyra-way" on the viol meant playing from tablature notation in a polyphonic style. Most players of plucked strings such as lute and guitar are familiar with tablature and, as a result, have a decisive advantage when attempting to explore this music. Other factors that make lyra viol repertory potentially attractive to the modern guitarist are its chordal textures, similarities in physical properties of the instruments, and many points of connection regarding the principles of left hand technique. The purpose of this study is two-fold: 1) to illuminate the historical and cultural context of the seventeenth-century English lyra viol music in general and that of Tobias Hume (c. 1579-1645) in particular; and 2) to present an idiomatic transcription for the modern guitar of four representative pieces from Hume's 1605 collection Musicall Humours. Musicall Humours, published in London in 1605, is one of the first and most significant collections of music for the lyra viol. The collection is both ambitious and groundbreaking, being the largest repertory of solo music for the lyra viol by a single composer in the early seventeenth century. Since the modern guitar, although not as contrapuntally facile as the keyboard, is nevertheless capable of executing two- or three-voice polyphony, reconstruction of the polyphonic implications of solo lyra viol music becomes the first step in creating an idiomatic arrangement. The differences in acoustical properties and technical capabilities between the viol and the modern guitar have to be taken into consideration when deciding on the degree to which harmony must be filled in. Generally, thinner textures of the lyra viol music, when transferred directly to the guitar, tend to sound incomplete. The arranger's musical sensitivity and intimate familiarity with both instruments must guide the final stages of the transcription process

The Bactericidal Irradiators

This article describes the irradiators are designed for disinfection of air and surfaces areas with a high risk of spreading germs. Disinfection of surfaces and air in the room is due to the effect on microorganisms bactericidal UV radiation with a wavelength of 253.7 nm. Inactivation of microorganisms is due to the messages they are a sufficient dose of UV radiation. The exposure dose or the amount of energy supplied to microorganisms is the main characteristic of the installation of UV disinfection. This equipment ensures the implementation of sanitary-epidemiological norms in the air, significantly reducing the concentration of microorganisms in the air. This allows, first, to significantly reduce the incidence of persons in the premises, and to improve the quality of finished products and raw materials in production, to reduce the number of chemicals used in traditional methods of disinfection of the premises

Corpus luteum of the domestic cat and lynx

Der Gelbkörper (corpus luteum, CL) ist eine transitorische Drüse, die im Ovar nach der Ovulation gebildet wird und durch ihre Progesteron-(P4)-Produktion die Trächtigkeit unterstützt. Bei allen bisher untersuchten Säugetieren endet die sekretorische Aktivität der CL mit dem Ende der Trächtigkeit oder Laktation, danach werden die CL abgebaut. Der Zyklus von Katzenartigen, wie etwa der Hauskatze, folgt dem gleichen Muster. Anders verläuft der Zyklus bei Luchsen. Beim Eurasischen Luchs (Lynx lynx) und beim Pardelluchs (Lynx pardinus) persistieren die CL nach der Geburt für mehr als zwei Jahre und sezernieren weiter P4. Die vorgestellte Arbeit sollte die Funktion persistierender (per) CL im Luchs untersuchen und die Fortpflanzung von Katzen weiter aufklären. Dazu wurden grundlegende histologische und hormonelle Aspekte der Lutealphase analysiert und der Einfluss des apoptotischen Systems sowie die Rezeptivität gegenüber Steroiden bei der Regulation der CL-Funktion betrachtet. Die CL von Hauskatzen und Luchsen wurden histomorphologisch unterteilt. In allen Proben wurden intraluteales P4 und Östrogene bestimmt. Weiterhin wurde die mRNA- und, wenn möglich, die Proteinexpression der proapoptotischen Faktoren BAX, Caspase-3, FAS, Tumor necrosis factor (TNF), TNF Rezeptor 1 (TNFRSFA1) und der Überlebensfaktoren (BCL2, TNFRSFB1), sowie des Progesteronrezeptors (PGR), der PGR-Membrankomponente (PGRMC) 1 und 2, des Östrogenrezeptors (ESR) 1 und 2, des G-Protein-gekoppelten Östrogenrezeptors 1 (GPER1) und des Androgenrezeptors (AR) gemessen. Die Ergebnisse weisen darauf hin, dass die Lutealphase der Hauskatze durch FAS, Caspase-3 und die TNF Rezeptoren 1 und 2 reguliert sein könnte. Steroide könnten über ihre Rezeptoren PGR, PGRMC1 und PGRMC2, ESR1 und AR wirken. Die physiologische Persistenz der CL beim Luchs könnte über BCL2, FAS, TNFRSFB1, PGRMC1, PGRMC2, ESR1, GPER1 und AR vermittelt werden.Corpus luteum (CL) is a transitory gland which forms in the ovary after ovulation and supports the pregnancy with its production of progesterone (P4). In all mammals studied so far, the CL loses its secretory activity after pregnancy and regresses from the ovary. The feline luteal cycle follows the same pattern, and CL of the domestic cat functionally and structurally regress after lactation. However, the story is different for the lynx. In the Eurasian (Lynx lynx) and Iberian (Lynx pardinus) lynx, CL persist after parturition, weaning and for up to two years, still retaining their ability to secrete P4. Current work was initiated to understand the control of unusual persistent (per) CL in lynx and to learn more about feline reproduction in general. For this, studies on the basic histological and endocrinological aspects of the feline luteal phase, as well as potential involvement of systems of apoptosis and steroid receptivity in the CL regulation were performed. Collected CL from domestic cats and lynx were classified based on their histomorphology. In all samples, intraluteal P4 and estrogens were measured. Moreover, mRNA and where possible protein levels were determined for pro-apoptotic BAX, caspase-3, FAS, tumor necrosis factor (TNF), TNF receptor 1 (TNFRSFA1), pro-survival BCL2, TNFRSFB1, and for progesterone receptor (PGR), PGR membrane components (PGRMC) 1 and 2, estrogen receptors (ESR) 1 and 2, G protein-coupled estrogen receptor 1 (GPER1) and androgen receptor (AR). The results suggest that the luteal phase of the domestic cat is potentially regulated by caspase-3, FAS, TNFRSF1A, TNFRSF1B, and by actions of steroids via PGR, PGRMC1, PGRMC2, ESR1 and AR. Physiological persistence of Iberian lynx CL might be mediated by BCL2, FAS, TNFRSFB1, PGRMC1, PGRMC2, ESR1, GPER1 and AR. Current work indicates profound differences between the CL function and regulation in domestic cats and lynx, and promotes a highly species-specific approach in reproduction studies

The role of law for improving municipal solid waste management: comparing Russia and Sweden (EU).

Waste generation increases, and its management is one of the global challenges. Improper waste management creates many problems, but on the other hand, effective waste management can save natural resources, minimize GHG emissions, and provide additional workplaces. Sweden has already achieved some successful results in managing household waste, while modern Russia only began to reform the municipal solid waste management system in December 2014. This study makes a legal comparison of the Russian and the Swedish (EU) framework waste legislations, using the functional method of comparative law. The results show that Russia has already introduced many institutions, which are similar to those in the Swedish (EU) waste legislation. Nevertheless, there is still a huge potential to make the municipal solid waste management system in Russia more effective by improving framework waste legislation. Based on the findings from the comparison, there are following recommendations to Russia: to establish a separate waste collection system on the Federal level; make producers responsible for the whole life cycle of waste, including its waste management (from collection till disposal); correct the waste hierarchy; introduce the concepts of “preparing for re-use”, “re-use”, and a waste prevention program; change the norm of waste recovery to the recycling target

Semen proteome and transcriptome of the endangered black-footed ferret (Mustela nigripes) show association with the environment and fertility outcome.

The ex situ population of the endangered black-footed ferret (Mustela nigripes) has been experiencing declines in reproductive success over the past 30 years of human-managed care. A potential cause may be environmental-dependent inbreeding depression with diet being one of the contributing factors since ferrets are not fed their natural diet of prairie dogs. Here, we generated and analyzed semen proteome and transcriptome data from both wild and ex situ ferrets maintained on various diets. We identified 1757 proteins across all samples, with 149 proteins unique to the semen of wild ferrets and forming a ribosomal predicted protein-protein interaction cluster. Wild ferrets also differed from ex situ ferrets in their transcriptomic profile, showing enrichment in ribosomal RNA processing and potassium ion transport. Successful fertility outcomes documented for ex situ ferrets showed the strongest association with the semen transcriptome, with enrichment in genes involved in translation initiation and focal adhesion. Fertility also synergized with the effect of diet on differentially expressed transcriptomes, mainly affecting genes enriched in mitochondrial function. Our data and functional networks are important for understanding the causes and mechanisms of declining fertility in the ex situ ferret population and can be used as a resource for future conservation efforts
