On the status of expansion by regions

We discuss the status of expansion by regions, i.e. a well-known strategy to obtain an expansion of a given multiloop Feynman integral in a given limit where some kinematic invariants and/or masses have certain scaling measured in powers of a given small parameter. Using the Lee-Pomeransky parametric representation, we formulate the corresponding prescriptions in a simple geometrical language and make a conjecture that they hold even in a much more general case. We prove this conjecture in some partial cases and illustrate them in a simple example.Comment: Published version: presentation improved, Section 7 delete

Entendimento poético como entrada inicial de ser-no-mundo

Comprehension of modern poetic phenomena is based on Heidegger’s fundamental ontology and Gadamer's hermeneutics. The rhythm of poetry cuts through the inner space of a thing, as agitated movements cut through the air, and almost every poetic line exists in its own special inclination, which makes the poems become voluminous. The composition of words in poetry is shifted and relabeled as if over tightened by a single rhythmic impulse, which also changes the state of literature. The initial occurrence of being-in-the-world through poetic understanding – these are the word-whistlers and word-spells from which verses are created, can be formed (and are added) into meaningful phrases, but their nature remains the same: mental and impulsive, in fact, pre-speech. According to Heidegger, Poetry is regarded as the initial mode of realization of the language. The essence of language – speech – permeates all existentials (being-preunderstanding, mood), in its original mode, speech is revealed in the self-pronunciation of being-in-the-world, that is, in finding the word-in-being-in-the-world. Since the pronunciation of meaning in words occurs simultaneously with understanding, poetic pronunciation is the place for the most complete manifestation of meaning in language.La comprensión de los fenómenos poéticos modernos se basa en la ontología fundamental de Heidegger y la hermenéutica de Gadamer. El ritmo de la poesía atraviesa el espacio interior de una cosa, como movimientos agitados cortan el aire, y casi todas las líneas poéticas existen en su propia inclinación especial, lo que hace que los poemas se vuelvan voluminosos. La composición de las palabras en la poesía se desplaza y se vuelve a etiquetar como si estuviera más apretada por un solo impulso rítmico, que también cambia el estado de la literatura. La aparición inicial del ser en el mundo a través de la comprensión poética: estos son los silbadores de palabras y los hechizos de palabras a partir de los cuales se crean los versos, se pueden formar (y agregar) en frases significativas, pero su naturaleza sigue siendo la misma: Mental e impulsivo, de hecho, pre-discurso. Según Heidegger, la poesía es considerada como el modo inicial de realización del lenguaje. La esencia del lenguaje, el habla, impregna todos los existenciales (ser un pre-entendimiento, estado de ánimo), en su modo original, el habla se revela en la auto-pronunciación de ser-en-el-mundo, es decir, en encontrar la palabra-in estar en el mundo Dado que la pronunciación del significado en palabras ocurre simultáneamente con la comprensión, la pronunciación poética es el lugar para la manifestación más completa del significado en el lenguaje.A compreensão dos fenómenos poéticos modernos baseia-se na ontologia fundamental de Heidegger e na hermenêutica de Gadamer.

Optimization of Nanostructuring Burnishing Technological Parameters by Taguchi Method

On the basis of application of Taguchi optimization method, an approach for researching influence of nanostructuring burnishing technological parameters, considering the surface layer microhardness criterion, is developed. Optimal values of burnishing force, feed and number of tool passes for hardened steel AISI 420 hardening treatment are defined

Factors influencingmicrobial transmission in a meat processing plant

The review paper examines the main risk factors for microbial contamination of meat at different stages of its processing. Particular emphasis has been placed on primary animal processing being the most hazardous in terms of microbial contamination of meat. Carcass cross-contamination most frequently occurs during skinning and evisceration since hides and the digestive tract are the primary sources of microbial pathogens. It is necessary to observe stringent sanitary and hygienic rules when performing these operations. Continuous cold chain management along all following stages of meat processing and control of the sanitary status of cold chambers during meat storage are of extreme importance. An increase in the microbial counts due to the high number of manual operations was observed during meat cutting, boning, and trimming. Subsequent stages of meat processing, including mincing, curing, the addition of spices, also promote significant microbial growth. Strict control regarding detection of dangerous pathogens, especially L. monocytogenes, is needed at this stage. In general, to minimize problems linked with meat and meat product safety, it is necessary to take timely measures on sanitary treatment of meat processing facilities, including the prevention of biofilm formation

KLEINE–LEVIN SYNDROME AFTER USE OF RECREATIONAL DRUGS

Kleine–Levin syndrome (KLS) is characterized by sleep attacks lasting several hours or days with imperative onset and awakening difficulty. The syndrome belongs to rare and little studied diseases not only in our country, but also throughout the world. It was first described in 1786. The diagnostic criteria for KLS include: 1) complaints of excessive somnolence; 2) sleepiness episodes lasting at least 18 hours daily; 3) at least 1–2 annual hypersomnia episodes lasting 3 days to 3 weeks; 4) predominance generally in adolescent males; 5) characteristic changes at polysomnographic study; 6) no relationship of hypersomnia to other somatic or mental disorders, such as epilepsy or depression; 7) no association with other sleep disorders, such as narcolepsy, sleep apnea, or nocturnal myoclonus. The etiology of the syndrome remains unknown. The disease may occur in the presence of trauma, metabolic disturbances, and other diseases. The likely etiology is considered to be viral or postinfection autoimmune encephalitis involving chiefly the hypothalamus. No specific treatment for KLS has been developed at present.The authors consider the historical description of the syndrome, its presumed etiology, pathogenesis, and clinical manifestations, including the results of additional studies. They describe their observed clinical case of KLS that manifested itself as hypersomnia, hyperphagia, and psychopathic disorders and developed when using amphetamine and cannabinoids for the treatment of traumatic brain injur

Tensor analyzing power Ayy in deuteron inclusive breakup at large Pt and spin structure of deuteron at short internucleonic distances

The Ayy data for deuteron inclusive breakup off hydrogen and carbon at a deuteron momentum of 9.0 GeV/c and large Pt of emitted protons are presented. The large values of Ayy independent of the target mass reflect the sensitivity of the data to the deuteron spin structure. The data obtained at fixed $x$ and plotted versus Pt clearly demonstrate the dependence of the deuteron spin structure at short internucleonic distances on two variables. The data are compared with the calculations using Paris, CD-Bonn and Karmanov's deuteron wave functions.Comment: 4 pages, 2 figures, talk given at the SPIN2004 Conf., 10-16 Oct. 2004, Triest, Ital

FUNCTIONAL FOOD COMPOSITIONS BASED ON WHEY PROTEIN ISOLATE, FISH OIL AND SOY PHOSPHOLIPIDS

The aim of the research was to study the impact of whey protein isolate on the solubility and oxidative stability of the lipid composition based on soy phosphatidylcholine and fish oil. The relationship between the molecular parameters (density; ζ-potential) of the formed complex particles and their functional properties was found using laser light scattering (static, dynamic, electrophoretic) and spectrophotometry. The studied compositions could be used as the basis for the development of multifunctional food additives with an objective of the enrichment of foods and beverages with omega-3 polyunsaturated fatty acids (PUFAs). The main advantages of such composition are a high level of protection of the lipids against oxidation and degradation, a high solubility in an aqueous medium and the clean label.The aim of the research was to study the impact of whey protein isolate on the solubility and oxidative stability of the lipid composition based on soy phosphatidylcholine and fish oil.
