Для обеспечения надлежащего качества и безопасности алкогольной продукции перед поставкой ее потребителям выполняется определение количественного содержания летучих компонентов. Данный контроль выполняют на газовых хроматографах. Количественный расчет значений концентраций выполняют по методу внешнего стандарта и по методу внутреннего стандарта. Метод внешнего стандарта используется в межгосударственных стандартах: ГОСТ 30536-2013, ГОСТ 31684-2012, ГОСТ 33833-2016, ГОСТ 33834-2016, ГОСТ 33408-2015, ГОСТ 31684-2012 и в государственных стандартах ГОСТ Р 52363-2005 и СТБ ГОСТ Р 51698-2001. С целью достижения высокой достоверности получаемых данных при контроле качества и безопасности алкогольной продукции, уменьшения материальных, финансовых и трудовых затрат предложен инновационный метод, заключающийся в использовании этилового спирта, содержащегося в испытуемом образце, в качестве внутреннего стандарта. Эффективность метода продемонстрирована на примере сравнительного анализа результатов определения количественного содержания летучих компонентов в широком спектре алкогольной продукции, выполненного по используемому в настоящее время методу внешнего стандарта и по предложенному методу. Показано, что для валидации метода и последующего его внедрения в практику испытательных лабораторий не требуется каких-либо дополнительных материальных, финансовых или трудовых затрат.

To ensure the proper quality and safety of alcoholic beverages, the quantitative content of volatile compounds is determined before delivery to consumers. This control is performed on gas chromatographs. The quantitative calculation of the concentration values is carried by external and internal standard methods. The external standard method is used in standards: GOST 30536-2013, GOST 31684-2012, GOST 33833-2016, GOST 33834-2016, GOST 33408-2015, GOST 31684-2012 and in state standards GOST R 52363-2005 and STB GOST R 51698-2001. In order to achieve high reliability of the data obtained when controlling the quality and safety of alcoholic beverages, and to reduce material, financial and labor costs, an innovative method is proposed. This method is based on using ethyl alcohol, contained in the test sample, as an internal standard. The effectiveness of the method is demonstrated by the example of a comparative analysis of the results of determining the quantitative content of volatile compounds in a wide range of alcoholic beverages, performed according to the currently used external standard method and according to the proposed method. It is shown that for validation the method and its subsequent implementation into the practice of testing laboratories does not require any additional material, financial or labor costs.
Flows of vector fields: classical and modern
Authors: Lellis Camillo De
Published: October 2021

Consider a (possibly time-dependent) vector field v on the Euclidean space. The classical Cauchy-Lipschitz (also named Picard-Lindelöf) Theorem states that, if the vector field v is Lipschitz in space, for every initial datum x there is a unique trajectory γ starting at x at time 0 and solving the ODE γ̇ (t) = v (t, γ (t)). The theorem looses its validity as soon as v is slightly less regular. However, if we bundle all trajectories into a global map allowing x to vary, a celebrated theory put forward by DiPerna and Lions in the 80es show that there is a unique such flow under very reasonable conditions and for much less regular vector fields. A long-standing open question is whether this theory is the byproduct of a stronger classical result which ensures the uniqueness of trajectories for almost every initial datum. I will give a complete answer to the latter question and draw connections with partial differential equations, harmonic analysis, probability theory and Gromov's h-principle.
Large stochastic systems of interacting particles
Authors: Jabin Pierre-Emmanuel
Published: October 2021

I will present some recent results, obtained with D. Bresch and Z. Wang, on large stochastic many-particle or multi-agent systems. Because such systems are conceptually simple but exhibit a wide range of emerging macroscopic behaviors, they are now employed in a large variety of applications from Physics (plasmas, galaxy formation...) to the Biosciences, Economy, Social Sciences.
The number of agents or particles is typically quite large,
with 1020 - 1025 particles in many Physics settings
for example and just as many equations.Analytical or numerical studies of such systems are potentially very complex leading to the key question as to whether it is possible to reduce this complexity,
notably thanks to the notion of propagation of chaos(agents remaining almost uncorrelated).
To derive this propagation of chaos,
we have introduced a novel analytical method,
which led to the resolution of two long - standing conjectures:
The quantitative derivation of the 2 - dimensional incompressible Navier - Stokes system from the point vortices dynamics;
The derivation of the mean - field limit
for attractive singular interactions such as in the Keller - Segel model
for chemotaxis and some Coulomb gases.
Displacement convexity and mean-field games
Authors: Gomes Diogo
Published: October 2021

In the theory of mean-field games (MFGs), a priori estimates play a crucial role to prove the existence of classical solutions. In particular, uniform bounds for the density of players' distribution and its inverse are of utmost importance. Here, inspired by previous results in the optimal transport theory, we investigate a priori bounds for a first-order planning problem with a non-vanishing potential and establish a displacement-convexity property. Using Moser's iteration method, we show that if the potential satisfies a certain smallness condition, then a displacement-convexity property holds. This property enables Lq bounds for the density. In the one-dimensional case, the displacement-convexity property also gives Lq bounds for the inverse of the density. Finally, using these Lq estimates and Moser's iteration method, we obtain L1 estimates for the density of the distribution of the players and its inverse. We conclude with an application of our estimates to prove the existence and uniqueness of solutions for a first-order mean-field planning problem.
A game theoretical approach for a nonlinear system driven by elliptic operators
Authors: Rossi Julio D.
Published: October 2021

This talk is based on the interplay between partial differential equations and probability.
We find approximations using game theory to viscosity solutions to an elliptic system governed by two different operators(the Laplacian and the infinity Laplacian).
We analyze a game that combines Tug - of -War with Random Walks in two different boards with a positive probability of jumping from one board to the other and we prove that the value functions
for this game converge uniformly to a viscosity solution of an elliptic system as the step size goes to zero.
In addition,
we show uniqueness
for the elliptic system using pure PDE techniques.

The brain's waterscape
Authors: Rognes Marie E.
Published: October 2021

Your brain has its own waterscape: whether you are reading or sleeping, fluid flows around or through the brain tissue and clears waste in the process. These physiological processes are crucial for the well-being of the brain. In spite of their importance we understand them but little. Mathematics and numerics could play a crucial role in gaining new insight. Indeed, medical doctors express an urgent need for modeling of water transport through the brain, to overcome limitations in traditional techniques. Surprisingly little attention has been paid to the numerics of the brain’s waterscape however, and fundamental knowledge is missing. In this talk, I will discuss mathematical models and numerical methods for the brain's waterscape across scales - from viewing the brain as a poroelastic medium at the macroscale and zooming in to studying electrical, chemical and mechanical interactions between brain cells at the microscale.
Mining Impact on Livelihoods of Farmers of Asutifi North District, Ghana
Authors: Agariga Felix , Abugre Simon , Siabi Ebenezer K. , Appiah Mark
Published: October 2021

Local communities in Ghana are heavily reliant on agriculture for their livelihoods. However, they are increasingly shifting from engaging in agriculture to mining. This study was undertaken to assess the impact of mining (both small and large scale) on the livelihoods of community members of Kenyasi, Asutifi North District in Ghana. Data were collected from 201 farming households who were selected randomly and interviewed for a variety of information. The questionnaire responses received from the respondents were classified into items and each item's responses were tallied. The results of the studies show that the farmers’ livelihood systems were affected by the mining operations occurring around their communities. Water pollution, displacement of farmers from their lands, degradation of agricultural lands, and an increase in social vices and higher dropout rates of students from schools are some of the reported consequences of the mining activities. The pollution of the water resources poses a serious threat to the health and livelihood systems of these farmers as they depend on the water resources for agriculture and domestic use. In this study, we project that there could be increased grievances over scarce land resource and food insecurity that could lead to conflicts in the mining areas. The lack of land resources could have a tremendous effect on the social, economic, and political climate of a country and must be considered and addressed as some of the most immediate threats to Ghana's national security.

Published: October 2021

This paper presents the findings of a study that investigated the nexus between the parental level of education and the level of the English language achievement at the Ordinary Level (O/Level) Examination. Determining how socio-economic factors affect the achievement level of English, exploring what socio-economic factors affect the achievement of the English language, and identifying the primary socio-economic factors were the objectives. A non-experimental cross-sectional research design was used in conducting the study. The sample consisted of 291 volunteer participants from six schools in the western province. We administered a research-team designed Likert scale type questionnaire to gather the data. The instrument was pilot-tested with 74 participants. In a statistical approach to data analysis, a regression analysis was run in SPSS (version 26). Findings showed that the English language proficiency of the participants increased by 0.691 for each education level of the father, and it was increased by 0.789 for each education level of the mother. Equitable teaching of the English language, availing more time and classwork to improve the achievement levels of the English language, and using quality inputs to give more support to the students who receive lower grades were suggested as part of recommendations.

Published: October 2021

În condițiile unui viitor tot mai incert, pentru că timpul trecut nu poate fi recuperat, singurul la îndemână rămâne cel din viitor. Așadar, planificarea apărării este, de fapt, despre planificarea unui viitor incert, despre reducerea nivelului de incertitudine sau despre creșterea nivelului de toleranță la incertitudine. De aceea, considerăm că este momentul să trecem la planificarea prospectivă, la reprioritizarea componentelor conducerii, cu accent pe previziune, cu atât mai mult cu cât observăm noul specific al mediului de securitate, în vederea alegerii, dezvoltării și menținerii acelor capabilități care să răspundă provocărilor actuale și viitoare.

            În cadrul acestui articol vom analiza toate aceste aspecte, în încercarea de a evidenția faptul că integrarea eficientă a acelor elemente care conduc la obținerea și menținerea capabilităților optime trebuie să reprezinte o acțiune sinergică în demersul creșterii eficacității acțiunilor militare.

Authors: DUȚU Daniel-Mihai , BADIU Teodor
Published: October 2021

Această lucrare prezintă rolul serviciilor de intelligence în politica externă americană, utilizând ca studiu de caz conflictul din Afganistan din perioada 1979-1989. Astfel, lucrarea are în vedere acțiunile (și inacțiunile) serviciilor de intelligence americane, scoțând în evidență limitările serviciilor în acea perioadă. Pentru acestea, este important de prezentat atât contextul declanșării invaziei din Afganistan, cât și cele două perspective (americană și sovietică) asupra acestui conflict. Am considerat necesară și o analiză a perspectivei sovietice asupra conflictului și, mai ales, asupra intervenției americane în Afganistan, pentru a prezenta cât mai obiectiv contextul și desfășurarea evenimentelor. Folosind documente relevante, dar și poziții și mărturii ale unor oficiali care au lucrat în CIA (Central Intelligence Agency), în perioada conflictului din Afganistan, lucrarea arată modul în care deciziile de politică externă au fost luate de către administrațiile de la Washington, care s-au succedat în perioada 1979-1989, dar și modul în care serviciile de intelligence americane au influențat procesul decizional și, în mod evident, evoluția conflictului.

Published: October 2021

This study aimed to determine the enthalpy index in three municipalities of Mato Grosso, to characterize the bioclimatic profile for the poultry industry. In the research, the compensated daily dry bulb temperature and the daily average relative humidity were used. The data corresponding to a historical series of 35 years, between 01/01/1985 and 12/31/2020, recorded in conventional meteorological stations in the municipalities of Canarana, Nova Xavantina, and Santo Antônio de Leverger, available in the Meteorological Database for Teaching and Research of the National Institute of Meteorology (INMET). Then, monthly descriptive statistics of the historical series were determined and bar plot graphs with enthalpy values were developed. These graphs included the lower and upper enthalpy limits, suitable for laying hens and broilers, to qualify the thermal conditions of environmental comfort in the three municipalities of Mato Grosso. It was concluded that the enthalpy index made it possible to characterize the bioclimatic profile of the mentioned municipalities for poultry farming, according to the months of the year. The natural thermal conditions in these municipalities were not favorable to poultry farming, requiring extra investments in the air conditioning of the sheds. The increase in thermal discomfort for broilers was accentuated from the fourth week of the production cycle. The applied methodology presented itself as an adequate tool to assist in the elaboration of projects related to environmental changes in aviaries.

SANCTUARIES BEARING THE NAME OF ST. DAVID ON THE TERRITORY
OF HISTORICAL ARMENIA

A group of sanctuaries are known thus far bearing the name of St. David. There are about ten sanctuaries of the kind but often it is impossible to clear up who that St. David was, to whom the given sanctuary is devoted. The most prominent sanctuary of Western Armenia devoted to St. David (the monastery Apranits, XVII century, known as St. David of Dvin) was in the historical region Derjan, on the territory of which two well-known huge (5-6 m of height) khachkars were erected. Within the boundaries of the contemporary RA there are two most popular sanctuaries named St. David. One of them is situated in the vicinity of the village Getazat of Ararat region and is devoted to St. David of Dvin. This is one of the rare cases when it is certain who the saint of the sanctuary is. The second one is in the village Nor Armavir (Armavir region). That is a prominent pilgrimage site and is mentioned since the beginning of the XIX century. The both over mentioned sanctuaries are significant and beloved pilgrimage sites both for Armenians and for Assyrians of Armenia. The pilgrimage holiday for the both is the Sunday following Easter. In our days these sanctuaries maintain their mass pilgrimage in the frame of which versatile rites having special purposes are executed.
A different case is the chapel Ardar (Righteous) David of the village Parpi, in the case of which it is not quite clear if it bears the name of the ogre described in legends. Nevertheless, in Parpi a different legend is told about the brave warrior Righteous David.
Documentary Evidence about the Year of Birth of Vasil Levski
Authors: Mitev Plamen , Boykov Grigor
Published: October 2021

Bulgarian historiography did not find to date a documentary source based evidence that firmly establishes 6 July 1837 as the birth date of Vasil Levski. Therefore, other hypotheses placing the birth of Levski in 1846 or 1843 have lately been put forward. The present article examines data from the population registers of Karlovo, kept in the Ottoman archives in Istanbul, and argues that 1840 is Vasil Levski’s most probable birth date.

Published: October 2021

En Nicaragua no existen estudios recientes sobre descripciones anatómicas de las características y propiedades que poseen las maderas. El objetivo de este estudio fue determinar las características macroscópicas, organolépticas y dos propiedades físicas de las especies comerciales del país: Cedro (Cedrela odorata L.) y Laurel [Cordia alliodora (Ruiz & Pav.) Oken]. Se seleccionaron dos individuos de cada especie; las muestras de Cedrela odorata se recolectaron en León y las de Cordia alliodora en Masaya. Para la corta de los árboles se utilizó la norma técnica 458 de la Comisión Panamericana de Normas Técnicas. Las descripciones de las características macroscópicas y organolépticas se realizaron en seis muestras de cada árbol, con una sierra manual se obtuvieron probetas de 3*3 cm, se utilizaron limas MIRCA P80, P600, P1000; con el Xilotrón se obtuvieron imágenes de las caras transversales y se apreció las estructuras. Para determinar las propiedades físicas se utilizaron probetas de 5*5 cm, el peso de la madera húmeda y anhidra se determinó con una balanza analítica, luego se aplicaron ecuaciones para estimar el contenido de humedad y la densidad básica. Cordia alliodora presentó porosidad difusa; vasos solitarios en su mayoría, parénquima paratraqueal rómbico. Albura color beige, duramen café claro, olor agradable a madera dulce, sabor no distintivo, con poco brillo o lustre, grano normalmente recto, textura fina y homogénea y veteado superpuesto.

Para el departamento de Antioquia y para las organizaciones públicas que le acompañan en la gestión económica, sociocultural y ambiental, educativa y demás conexas relevantes para la función pública, es de vital importancia buscar siempre eliminar o, en su defecto, menguar la existencia de actividades ilegales en el territorio departamental y, de esa manera, coadyuvar a la generación de condiciones sociales que beneficien la legalidad de las rentas en el Departamento como compromiso social y público ineludible. De la misma manera, se ha venido trabajando en ejercicios de cooperación académica y jurídica entre algunas instituciones del Departamento de Antioquia que han decido privilegiar la construcción de proyectos de investigación alrededor de la defensa del patrimonio público y las buenas prácticas que propendan por fortalecer los ingresos y el erario públicos con los cuales se lleva a cabo la inversión social en Antioquia.

Dekonstruksi Derrida terhadap Humanisme Barat
Authors: Ruhupatty Chris
Published: October 2021

Tulisan ini menyajikan sebuah uraian tentang bagaimana Jacques Derrida (1930-2004) melakukan dekonstruksi terhadap proposisi filsafat Barat tentang hakikat manusia di bawah wacana humanisme. Melalui tulisan ini, kita juga dapat menemukan bahwa dekonstruksi tidak bermakna sebuah tindakan untuk merekonstruksi/memperbaiki struktur sebuah proposisi agar mendapatkan sebuah proposisi yang lebih baik dibandingkan sebelumnya, atau juga tidak bermakna sebuah tindakan untuk menghancurkan/merobohkan sebuah proposisi dengan tujuan untuk menggantikannya dengan sebuah proposisi yang baru. Faktanya, dekonstruksi sebenarnya hanya sebuah tindakan penyingkapan metafisika kehadiran di dalam sejarah filsafat Barat untuk menunjukkan bahwa filsafat Barat cenderung untuk menobatkan teks menjadi sebuah Kehadiran. Dengan demikian, dekonstruksi di dalam tulisan ini hanya akan menyingkapkan selubung metafisika kehadiran di dalam diskursus tentang manusia di bawah wacana humanisme tanpa bermaksud untuk memperbaiki atau menghancurkannya.

Maus y la ética de la representación después del Holocausto Narrativas post-traumáticas, elaboración y post-memoria. / Maus and the Ethics of Representation After the Holocaust Post-traumatic narratives, elaboration and post-memory.
Authors: Vetö Silvana
Published: October 2021

En este trabajo se examinarán algunos de los problemas éticos que el Holocausto ha planteado a los medios de representación de la historia, para luego ligar las distintas narrativas que resultan de dichas representaciones, con las posibilidades de duelo y elaboración. Se abordarán primero los planteamientos de Theodor Adorno respecto de las posibilidades del arte frente al sufrimiento. Luego se expondrán algunos aspectos del debate surgido al final de la década del 70 a propósito de la representación del Holocausto en medios de comunicación de masa y en la “alta” cultura. Se mostrará como persiste en ese debate una perspectiva dicotómica respecto del trauma, de la cual surgen dos tipos de narrativas post-traumáticas supuestamente irreconciliables, que no permiten una adecuada elaboración y un duelo satisfactorio respecto de las pérdidas implicadas en el acontecimiento traumático. Finalmente, analizaremos en detalle la novela gráfica Maus. Relato de un superviviente, cuya narrativa experimental permite cuestionar y deconstruir la dicotomía redención/aporía de manera novedosa, planteando nuevos problemas vinculados a la memoria del Holocausto y a la posibilidades de duelo.

In this work, we will focus on some of the ethical problems that the Holocaust has posed to the representation of historical limit-events. We will then link the different narratives emerging from these representations to the possibilities of mourning and elaboration. First, we will examine the German philosopher Theodor Adorno’s propositions concerning the possibilities of art in the face of suffering. Then, we will present some aspects of the debate that arose in the late 70s regarding the representation of the Holocaust in mass media and in ‘high’ culture. It will be shown how in this debate there persists a dichotomist perspective of trauma, which creates two supposedly irreconcilable types of post-traumatic narratives that do not permit an appropriate elaboration and mourning of losses caused by the traumatic event. Finally, we will analyze the graphic novel Maus. A Survivor’s Tale, whose experimental and open narrative allows an original questioning and deconstruction of the redemption/aporia dichotomy, putting forward new problems related to the memory of the Holocaust and the possibilities of mourning.
