The paper presents the results of research conducted during the years 2015–2020 and the analysis of the influence of changing climatic conditions during the year on plant development, the number of ...crops obtained from gooseberry, Josta, black currant, red currant and white currant. The average fruit harvest obtained for the studied species varies depending on several factors, especially on the species, variety and changing climatic conditions of the year. Among the studied species, the gooseberry is the most productive, followed by the hybrid Josta, the red currant, the black currant and the white currant. As a result, the analysis of the data obtained regarding the fruit production allowed us to establish that depending on the species, the harvest of gooseberry varied between 7.36-11.9 t/ha, on Josta between 4.7-8.2 t/ha, for black currant – 4.3-8.1 t/ha, red currant – 4.3-8.5 t t/ha and for white currant – 3.7-7.8 t/ha. The crop according to variety increases the harvest on gooseberry by 3.13 %, blackcurrant by 1.49%, red currant by 2.99 %, and the harvest of white currant is not influenced by variety. In the conditions of a favorable year (year 2015), high harvests were obtained for the black currant with 8.1 t/ha; in 2016 year for gooseberry with 11.8 t/ha, Josta – 8.2 t/ha, red currant – 8.5 t/ha, for white currant – 8.2 t/ha. In the conditions of an unfavorable year (year 2020 compared to 2016), the harvest decreased on gooseberry by 36.1%, Josta by 42.7 %, black currant by 46.9 %, red currant by 49.4%, white currant by 52.6 %.
Berries contain a high quantity of vitamin C and anthocyanin pigments, with high antioxidant capacity. The vitamin and pigment content normally decrease during processing. The aim of the present work ...was to study the effects of different preparation methods on changes in vitamin C and anthocyanin of berry fruits. The examined fruits were black currant, blackberry and josta. We used classical small-scale methods for maintaining the nutritional value of fresh fruit, made jam, bottled fruits, made juice and fruit syrup. Comparing the different processing done on the fruits, the cold juices had the highest antioxidant potential. Among the processes requiring heat, bottled fruits had higher antioxidant capacity than jams. The quick jam preparing method with 3-min boiling proved to be better than normal with 30 min boiling. The large amount of sugar added decreased the pigment content together with the fruit ratio in the final product. Blackcurrant products had higher anthocyanin and vitamin C concentrations than blackberry in all types of products. Josta contains a medium amount of antioxidants, it is a valuable fruit that expands the range of assortment for consumption.

En este artículo se reflexiona sobre las transmisiones televisivas de un conflicto sindical en Argentina. Para el análisis se utiliza el marco teórico elaborado por François Jost, y desde su ...perspectiva, se retoma el modelo de la promesa para identificar la promesa genérica correspondiente a los noticieros de televisión. A continuación se pone a prueba dicho modelo a partir del estudio de las secuencias televisivas de los noticieros que comunicaron un conflicto sindical de carácter emblemático: el de los trabajadores de subterráneos de la Ciudad de Buenos Aires. Se identifican las estrategias y operaciones recreadas por las emisoras televisivas para cumplir con su promesa genérica —es decir, la autentificante— de transmitir “la verdad objetiva” del conflicto en cuestión.

La chirurgie réparatrice de la pyramide nasale est l’une des premières interventions décrites dans l’histoire de la médecine. Au fil des siècles, les chirurgiens ont développé des techniques ayant ...pour but de reconstruire le nez traumatisé ou amputé par la maladie. C’est seulement à la fin du xixe siècle que la notion de rhinoplastie esthétique est apparue et depuis les techniques n’ont cessé d’évoluer pour s’affiner. Cette chirurgie représente aujourd’hui l’une des interventions esthétiques les plus pratiquées. La sophistication actuelle des techniques est l’aboutissement de plus d’un siècle d’histoire marqué par de nombreux chirurgiens. Toutes ces techniques résultent de la compréhension détaillée du nez anatomique, chirurgical et artistique.
One of the first surgical procedures described in the history of medicine is reconstructive surgery of the nose. Over the centuries, surgeons have developed techniques aimed at reconstructing noses amputated or traumatized by disease. The concept of aesthetic rhinoplasty was only introduced at the end of the 19th century. Since then, techniques have evolved toward constant ameliorations. Nowadays, this surgery is one of the most performed aesthetic procedures. Current technical sophistication is the result of over a century of history marked by many surgeons. All of these techniques derive from a detailed understanding of the anatomical nose from the surgical and artistic point of view.
La función de Jost F.sub.l es el concepto teórico que permite estudiar de una manera unificada los estados ligados, virtuales, dispersados y resonantes que pueden originarse en las interacciones ...entre dos sistemas cuánticos. En teoría de colisiones la función de Jost F.sub.l juega un papel muy importante, puesto que se relaciona de forma directa con la matriz de dispersión S. En la mayoría de los métodos existentes en teoría de colisiones para el cálculo de la función F.sub.l, primero es necesario conocer la solución regular del sistema tratado, la cual se obtiene via solución de la ecuación radial de Schrödinger, para poder hallar después la función F.sub.l. Con la metodología propuesta en este trabajo se obtiene una ecuación diferencial lineal ordinaria de segundo orden cuya solución en los límites asintóticos coincide con la función F.sub.l. La ventaja del trabajo presente es que al soluciónar la ecuación diferencial, mencionada antes, se puede obtener de manera directa la función F.sub.l, sin tener que hallar la solución regular del problema. Otra ventaja es que no importando las condiciones iniciales (reales) que se escojan para la solución de la ecuación diferencial, siempre se obtienen los mismos elementos de la matriz S. Como un ejemplo y prueba de la metodología, se resuelve dicha ecuacioín diferencial numéricamente, para la dispersión elástica de electrones por íatomos de hidrogeno en el estado base a bajas energías (e.sup.- + H(1s)), obteniendo para este sistema la función F.sub.l, los elementos de la matriz S y los corrimientos de fase, estos últimos se comparan con los calculados por Klaus Bartschat 1. Palabras claves: función de Jost, ecuacián diferencial, matriz de dispersion, corrimientos de fase. The function of Jost F.sub.l is the theoretical concept that allows to study in an unified way the bound, virtual, scattered and resonant states that can originate in the interactions between two quantum systems. In theory of collisions the function of Jost F.sub.l plays a very important role, since it is related in a direct way with the scattering matrix S. In most of the existent methods in theory of collisions for the calculation of the function F.sub.l first is necessary to know the regular solution of the treated system, which is obtained of the solution of the radial equation of Schrödinger, to be able to find the function F.sub.l later. With the methodology proposed in this work an ordinary lineal differential equation of second order it is obtained whose solution in the asymptotic boundary coincides with the function F.sub.l. The advantage of the present work is that solving the differential equation mentioned before one can obtain in a direct way the function F.sub.l without having to find the regular solution of the problem. Another advantage is that not caring the initial conditions (real) that are chosen for the solution of the differential equation, the same elements of the matrix S, are always obtained. As an example and test of the methodology, it is solved this differential equation numerically for the elastic scattering of electrons by hydrogen atoms in the ground state to low energy (e.sup.- + H(1s)), obtaining for this system the function F.sub.l, the elements of the matrix S and the phase shifts. The data obtained for the phase shifts are compared with the calculated by Klaus Bartschat 1. Key words: Jost function, differential equation, scattering matrix, phase shifts. A função de Jost F.sub.l é o conceito teárico que permite um estudo unificado de estados ligados, virtual, dispersos e de ressonância que podem surgir nas interações entre dois sistemas quânticos. Em teoría de colisões o função de Jost F.sub.l desempenha um papel muito importante, pois se relaciona diretamente com a matriz de dispersão S. Em a maioria dos métodos existentes em teoría de colisões para calcular a funcão F.sub.l, primeiro é necessário conhecer a solução regular do sistema tratado, que é obtida através da solução de a equação radial de Schrödinger, para encontrar depois a função F.sub.l. Com a metodologia proposta neste trabalho obtemos uma equação diferencial ordinaria lineal de segundo ordem cuja soluçao nos limites assintoticos coincide com a função F.sub.l. A vantagem deste trabalho á que a partir da solução da equaçao diferencial, acima mencionado, a funçcaão F.sub.l pode ser obtida diretamente, sem ter que encontrar a solução regular do problema. Outra vantagem e que nao importa as condições iniciais (real), que são escolhidos para a solução da equaçcãao diferencial, sempre se produzem os mesmos elementos da matriz S. Como um exemplo e testar de a metodologia, a equaçao diferencial e resolvido numericamente, para a colisão elastica de eletrons com atomos de hidrogenio no estado fundamental a baixas energias (e.sup.- + H(1s)), para este sistema e calculado F.sub.l, os elementos da matriz S e deslocamentos de fase, estes saão comparados com aqueles calculados por Klaus Bartschat 1. Palavras chaves: função de Jost, equacão diferencial, matriz de espalhamento, deslocamentos de fase.
