El reconocimiento como proceso de interacción comunicativa: elementos para una reflexión desde la salud pública
Authors: Fasanelli Roberto , Galli Ida , Cañón Rodríguez Maria F.
Published: December 2021

La reflexión propuesta en las páginas siguientes tiene como objetivo retornar a las prácti- cas operacionales de reconocimiento en el campo de situaciones de comunicación com- plejas centradas en la reciprocidad. La perspectiva epistemológica propuesta es la de la psicología social socioconstructivista. El marco teórico-metodológico es el de las represen- taciones sociales. A partir del rol de los actores involucrados en el proceso, en el ensayo se describen las tres distintas clases de variables que, en opinión de los autores, influyen en el reconocimiento mutuo: las variables psicológicas, las variables cognitivas y las variables sociales. Las dimensiones subyacentes de cada una de las variables consideradas se ana- lizan en detalle, subrayando los posibles efectos sobre las prácticas sociales relacionadas con los mismos. Estos muestran claramente que las influencias múltiples que entran en juego en la “situación comunicativa” de reconocimiento producen una realidad claramente compleja y ampliamente predeterminada por sistemas recíprocos de representación del otro, de la tarea y de la situación.

Published: December 2021

Objetivo Reportar los resultados del proceso de adaptación y evaluación psicométrica de dos escalas para medir la solastalgia en contextos relacionados con la construcción de embalses.Métodos Primero se adaptó al español la escala Environmental Distress Scale de Higginbotham et ál., que fue probada con una población ribereña del río San Jorge (Córdoba, Colombia). Luego se hicieron grupos focales y entrevistas con habitantes cercanos a Hidrosogamoso para comprender el concepto de solastalgia, asociado a la construcción de embalses. Finalmente se construyeron dos escalas, de 8 y 13 ítems, que fueron usadas con residentes cercanos a las centrales hidroeléctricas de Sogamoso (Santander) y El Quimbo (Huila), respectivamente. La validación incluyó la evaluación de unidimensionalidad con componentes principales y la evaluación de confiabilidad con alfa de Cronbach.Resultados Participaron 103 individuos de los alrededores del embalse de Hidrosogamoso y 277 individuos del embalse de El Quimbo. En ambas escalas se identificó un factor con eigenvalue de 3,95 y 8,12 en Hidrosogamoso y El Quimbo, respectivamente. Los coeficientes de Cronbach fueron de 0,8515 y 0,9441 para los grupos Hidrosogamoso y El Quimbo, respectivamente.Conclusiones Los resultados permitieron tener dos escalas en español de 8 y 13 ítems, siendo esta última la de mejor desempeño psicométrico. Así, no es posible tener solo una escala de solastalgia, debido a que debe ser adaptada al ambiente deteriorado o contaminado relacionado con la solastalgia.

Published: December 2021

Objetivo Evaluar la fuerza prensil en trabajadores sedentarios como escrutinio de riesgo cardiovascular.Método Se realizó un estudio transversal con personal administrativo. Se midió la fuerza prensil y se relacionó con las variables antropométricas, el nivel de estilo de vida adoptado por los trabajadores, estimado con la prueba FANTÁSTICO, y el nivel de Actividad física, valorado con el Cuestionario IPAQ.Resultados En 152 participantes, no se encontró asociación de la fuerza prensil con las mediciones de actividad física y estilos de vida. Tampoco con marcadores tempranos de riesgo cardiovascular. La población tenía buenos estilos de vida con alto nivel de sedentarismo. A diferencia de otras investigaciones, nuestra población tenía índices de comorbilidad muy bajos y no eran ancianos. Esto podría explicar los resultados diferentes.Conclusión La fuerza prensil no parece ser útil en las evaluaciones de programas de estilos de vida en trabajadores sedentarios adultos con bajo nivel de comorbilidades.

Published: December 2021

La enfermedad de Alzheimer (EA) es la más común de las demencias; es un problema de salud pública en el Mundo, pero en Colombia no hace parte de las prioridades del Estado. El presente ensayo aborda cómo el sistema de salud colombiano reconoce, identifica y provee servicios a los pacientes con EA, desde una óptica de la Justicia Social. En primera medida se evalúa la información generada por la academia, su correlato con la normativa vigente y su articulación. Se explora la lógica utilitarista del sistema de salud colombiano y el incentivo a la maximización de ganancias de los aseguradores y cómo esto ha llevado a los pacientes a exigir la restitución de derechos a través de la acción de tutela. Se explora el sistema de codificación y diagnostico usado para la generación de información y como esta es imprecisa en los canales de información consolidada. Por otra parte, se valora como el rol de la familia se hace parte fundamental del proceso, y cómo esta termina siendo víctima del mismo.  Finalmente, se plantea reflexiones de cómo pueden abordarse las dificultades identificadas desde una perspectiva de la Justicia Social.

Formal Rules to Produce Object Notation for EXPRESS Schema-Driven Data
Authors: Semenov Vitaly Adolfovich , Arishin Semen Vasilyevich , Semenov Georgii Vitalyevich
Published: December 2021

Recently, product data management systems (PDM) are widely used to conduct complex multidisciplinary projects in various industrial domains. The PDM systems enable teams of designers, engineers, and managers to remotely communicate on a network, exchange and share common product information. To integrate CAD/CAM/CAE applications with the PDM systems and ensure their interoperability, a dedicated family of standards STEP (ISO 10303) has been developed and employed. The STEP defines an object-oriented language EXPRESS to formally specify information schemas as well as file formats to store and transfer product data driven by these schemas. These are clear text encoding format SPF and STEP-XML. Nowadays, with the development and widespread adoption of Web technologies, the JSON language is getting increasingly popular due to it being apropos for the tasks of object-oriented data exchange and storage, as well as its simple, easy to parse syntax. The paper explores the topic of the suitability of the JSON language for the unambiguous representation, storage and interpretation of product data. Under the assumption that the product data can be described by arbitrary information schemas in EXPRESS, formal rules for the producing JSON notation are proposed and presented. Explanatory examples are provided to illustrate the proposed rules. The results of computational experiments conducted confirm the advantages of the JSON format compared to SPF and STEP-XML, and motivate its widespread adoption when integrating software applications.

Globalization urges the necessity of having world class leaders, and very frequently in its formation, is required to teach them computational tools to mainly improve their project management facilities. In order to give project management a greater quality, a very important point is to control and follow up all users’ diverse requirements, from the beginning to the end of each or any type of project: administrative, academic, engineering, software, video games, virtual and mixed reality, etc. This research shows a project requirements manager’s approach which allows knowing the specific requirements in each of its phases and give an advanced description of its various types and their traceability. This prototype promotes project requirement management best practices, and link them to the various areas of engineering, administration, planning and also with society, industry, commerce and academic sectors.
Optimization of ProVerif programs for AKE-protocols
Authors: Vinarskii Evgenii Maksimovich , Demakov Alexey Vasilyevich
Published: December 2021

Cryptographic protocols are used to establish a secure connection between “honest” agents who communicate strictly in accordance with the rules of the protocol. In order to make sure that the designed cryptographic protocol is cryptographically strong, various software tools are usually used. However, an adequate specification of a cryptographic protocol is usually presented as a set of requirements for the sequences of transmitted messages, including the format of such messages. The fulfillment of all these requirements leads to the fact that the formal specification for a real cryptographic protocol becomes cumbersome, as a result of which it is difficult to analyze it by formal methods. One of such rapidly developing tools for formal verification of cryptographic protocols is ProVerif. A distinctive feature of the ProVerif tool is that with large protocols, it often fails to analyze them, i.e. it can neither prove the security of the protocol nor refute it. In such cases, they resort either to the approximation of the problem, or to equivalent transformations of the program model in the ProVerif language, simplifying the ProVerif model. In this article, we propose a way to simplify the ProVerif specifications for AKE protocols using the El Gamal encryption scheme. Namely, we suggest equivalent transformations that allow us to construct a ProVerif specification that simplifies the analysis of the specification for the ProVerif tool. Experimental results for the Needham-Schroeder and Yahalom cryptoprotocols show that such an approach can be promising for automatic verification of real protocols.
Dynamic analysis of IoT systems based on full-system emulation in QEMU
Authors: Kovalenko Roman Dmitrievich , Makarov Alexey Nikolaevich
Published: December 2021

The sweeping evolution of the Internet of Things (IoT) requires the development of methods and tools for analyzing such devices. A significant part of similar devices run under operating systems (OS) of the Linux family. Direct application of existing tools for analyzing software (SW) of this class of devices is not always possible. In the process of researching embedded Linux OS, the ELF (embedded linux fuzz) tool was created, which is presented in this work. The article deals with the analysis of systems built exclusively on the basis of Linux kernels. ELF environment is designed for dynamic analysis of devices based on full-system emulation in QEMU. ELF was based on the following aspects: performing software testing and analysis of real devices in an environment as close as possible to their «native» execution environment; integration with existing fuzzing tools; the ability to conduct distributed analysis.
Precarious scenes
Authors: Chan Jonathan
Published: December 2021

This article examines how the 2019 Anti-Extradition Law Amendment Bill protests in Hong Kong, and the subsequent COVID-19 pandemic, has affected the indie music scene on a local level. It also explores the many ways that artists, bands and venue owners have sustained music activities and reflects on the impact that the pandemic has had on the author’s own research as a postgraduate student. The author discusses the changes that he has had to make following gig cancellations. The article concludes by considering how the pandemic has foregrounded performances of precarity in the scene’s activities, long before any pandemic or even protest movement occurred.
The natural philosophy of Antonius Andreae
Authors: Gensler Marek
Published: December 2021

Igual que su maestro, John Duns Escoto, Antoni Andreu no fue un naturalista, ni siquiera para los estándares de su época. Sin embargo, reconoció la importancia de la filosofía natural en el sistema de conocimiento aristotélico, que era el fundamento de la cosmovisión premoderna. Consecuentemente, abordó los problemas relacionados con las sustancias naturales en algunas de sus obras, sobre todo en sus Quaestiones de tribus principiis naturae, pero también en los comentarios sobre la Metafísica y las Categorías de Aristóteles y, ocasionalmente, en la Abbreviatio Operis Oxoniensis. Estos problemas incluyen la cuestión del sujeto de la física, los procesos físicos, con una atención especial a los procesos de generación y de corrupción, y las características de los cuerpos que son objeto de dichos procesos.
Notas sobre el primer sujeto de la metafísica según el comentario a la «Metafísica» de Antoni Andreu
Authors: Cabré-Duran María
Published: December 2021

En este artículo estudiaremos algunos elementos propios de la formulación del problema del sujeto de la metafísica tal y como aparece en el comentario de Antoni Andreu a la Metafísica aristotélica. Esta cuestión está estrechamente vinculada a la concepción de la univocidad aplicada al ser transcendental, pero también a la inclusión de las sustancias separadas en el dominio de la metafísica. La afirmación de un concepto de ser unívoco y real como sujeto-objeto de la metafísica es la base del realismo metafísico propuesto por Antoni Andreu.

Published: December 2021

The paper treats pseudo-Riemannian spaces permitting generalized φ(Ric)-vector fields. We study conditions for the existence of such vector fields in conformally flat, equidistant, reducible and Kählerian pseudo-Riemannian spaces. The obtained results can be applied for the construction of generalized φ(Ric)-vector fields that differ from φ(Ric)-vector fields. The research is carried out locally without limitations imposed on a sign of metric tensor.
Constructivism and the Problem of Responsibility
Authors:   Tomsk State University, Syrov V. N. , Agafonova E. V. ,   Tomsk State University
Published: December 2021

Based on the analysis of the methods of constructing historical narratives, the article examines the problem of the relationship between research strategies (realism/constructivism) and the responsibility of the author of the narrative for his product. It is argued that the constructivist strategy provides the most promising way to solve the problem, since it involves the production of statements in the first person as a way to separate tradition from innovation. Constructivist strategy is also built on a communicative relationship as a way to determine the reliability of statements. The above procedures can be considered necessary tools for the implementation and demonstration of taking responsibility for one's own discourse, and their absence should be interpreted as an explicit or implicit disclaimer.

In sustainable view and given the new climate and demographic phenomena, the mountains must be a clean living environment, supplier of energy, biodiversity and food for humans and animals, adequate safety measures and good management, with continued compliance with the balance agroforestry and preventing human depopulation and agricultural traditions and cultural degradation. Oligotrophic grasslands from GÃ¢rda de Sus village was a subject ofÂ Arnica Project (2004-2007, www.arnica-montana.ro). This project aimed at sustainable exploitation ofÂ Arnica montana L. species benefit and welfare of local people. So, oligotrophic grasslands have managed so as to maintain the speciesÂ Arnica montana L. in abundance-dominance as possible. Following this project was set into remote exploit local speciesÂ Arnica montana L. and that capitalize on the international market as certified product. Interests of entrepreneurs are to maintain the existing flora in the oligotrophic meadows. The obiective of our study is to evaluate the effect of low-inputs on a grassland ofÂ Arnica montanaÂ Â L. from boreal floor, GÃ¢rda de Sus, Apuseni Mountains, Romania. In Apuseni Mountains, extensive grazing and extensive meadow management practices have been typically for subsistencebased or small-scale farming systems in areas of low agriculture productivity. However, longer term effects of these grasslands need to be investigated.

Published: December 2021

Festuca ArundinaceaÂ Â is one of the most valuable fodder plants, successfully grown in RomÃ¢nia.Â Festuca Arundinacea crop quality depends on the quality of seeds, therefore vigour tests are essential, as they describe the behaviour of seeds under various growth conditions. The paper aims at assessing the quality ofÂ Festuca Arundinacea seeds and the efficiency of the methods to determine them. The biological material used consisted ofÂ Festuca Arundinacea seeds, Palma variety, stored in uncontrolled conditions, one year after harvest. The present paper assesses several seed parameters: total germination, normal seedlings, abnormal seedlings, dead seeds, seed weight, as well as the appearance of normal seedlings ( after 7 to 14 days) through three laboratory methods : BP (between paper) test ( V1, V2, V3, V4), sand S test (V5) and top of paper TP test (V6). Seed germination percentage for Palma variety ranged from 74% (V4) to 79% (V1 and V6). Low germination is especially caused by the large number of dead seeds, the main cause being the improper storage conditions. According to the results of this experiment, cluster analysis showed the efficiency of the BP test, without pre-cooling, and of TP test, in emphasizing the quality characteristics ofÂ Festuca arundinaceaÂ Â seeds, Palma variety. Sand test S, which is actually the hardest to run, is less suitable for this research.
Comparison Between some Corn Synthetic Populations Obtained from Transylvanian
Authors: MUNTEAN Leon , HAS Ioan , HAS Voichita , GULEA Alin
Published: December 2021

Synthetic varieties of corn are open-pollinated populations obtained by cross-pollination of a group of inbred lines. Besides the inbred lines, corn synthetics can be obtained from local populations or hybrids. In general, they are superior to local populations but not exceeding heterotic hybrids. The main advantage of corn synthetic varieties is that their heterosis does not diminish significantly in FÂ 2 generation. Interest in this biological category increased after 1999, when CIMMYT's considered viable alternatives in areas where use of hybrid seed is too expensive (especially in developing countries). Obtaining corn synthetics from local populations aims at enriching their gene pool with a large number of valuable genes derived from local populations that are characteristic to some agricultural areas. SCDA Turda tried to exploit the large number of local populations still existing in Romania, and obtained a series of synthetics intended for areas that still practice subsistence agriculture. To assess their value, we tested six synthetics obtained from local populations in comparison with one traditional synthetic derived from inbred lines; two locations and two experimental years have been considered and the conclusions have been included in this paper. Synthetic populations derived from a combination of local populations cannot be used as such in production due to their lower yield performance and low resistance to stalk breaking and falling. Nevertheless, they can be valuable sources of genes for the following traits: vegetative period, earliness, resistance to low spring temperatures, resistance toÂ Fusarium , precocity and the content of fat, protein, fiber and minerals.

Authors: PAHONI Corneliu
Published: December 2021

This work presents the results of laboratory experiments and field studies in harvesting of the maize grain crop by two combine harvesters: Claas Lexion 560 and Claas Lexion 750, both made in Germany. There are differences between this two combines at both constructive level and the degree of automation. This work has tracked the impact of the existing automation elements in the construction of the combines on the growth of their performance, by determining the work quality indexes and the energetic and operating indexes of the combines studied. The major difference has been done by both the values of the working capacities and the values of the operating coefficients, which were higher for the Claas Lexion 750 combine, compared to the values obtained by the Claas Lexion 560 combine. Overall, the Claas Lexion 750 combine has been proven better performance, the higher level of automation of this combine had done the difference.
Research Concerning Nitrogen Fixation in Fodder Systems Based on Italian Ryegrass
Authors: GHIOCEL Cristian , DRAGOMIR Neculai , VIDICAN Roxana , TOTH Sebastian , MORARU Nicoleta
Published: December 2021

In any agricultural system based on legumes, nitrogen balance should take into account the flow of NÂ 2 by legume species. In this flow, the amount of N2 fixed by legumes is considered a reserve amount of nitrogen which, through harvesting, is removed from the nitrogen balance. The aim of the present paper is to assess the amount of nitrogen fixed biologically (NFB) in some legume species sowed in association and of the share of this amount of NFB of the total amount of nitrogen from the productions obtained. Thus, in the fodder system made up of Italian ryegrass + red clover cultivated for two years, the amount of NFB in the first year was 60 kg/ha. If we relate the amount of NFB to the amount of nitrogen exported through the fodder biomass, we see that the share of NFB varies between 22 and 42%.

Published: December 2021

The purpose of this study is to quantify soil surface erosion using the Universal Soil Loss Equation in GIS environment and to assess its impact on soil humus reserve. The quantifying of soil surface erosion was performed by integrating in GIS the thematic raster representations of the erosion control parameters which exhibit spatial variability within the limiÂ ts of the study region (DobrovÄƒÅ£ Basin, The Central Moldavian Plateau, eastern Romania). Soil erodibility was computed according to ICPA (1987) standards, on the basis of soil type, texture and erosion degree, using a soil map of the basin at scale 1: 5000. Slope length was derived from a 20m resolution digital elevation model using SAGA-GIS software, while slope factor was determined according to the Romanian methodology by raising the slope values at the power of 1.5. Finally, the vegetation factor was computed on the basis of the normalized difference vegetation index derived from a 2001 Landsat image, using the equation proposed by Van der Knijff et al. (1999). Subsequently, we derived the potential soil erosion, controlled exclusively by soil-relief factors and the effective soil erosion, by integrating the effect of vegetation. The potential soil erosion show a mean value of 15.6 t/ha yr and a standard deviation of 16.6 t/ha yr. The integration of the vegetation effect decreases the mean value to 5.4 t/ha yr and the standard deviation to 6.7 t/ha yr. Most of the basinâ€™s surface (48.7%) falls into the reduced erosion risk class (2-8 t/ha yr), while the high and very high erosion risk classes group 7.3% of the basin. The assessment of the erosion impact on soil carbon stock was performed by coupling the USLE model with a HÃ©ninÂ -Dupuis mono-compartmental humus evolution model. The simulation was performed for the first 20cm of the soil profile, using a database of 224 soil profiles. The results of the simulation show that 76% of the soil profiles display a regressive evolution of the humus reserve under the impact of the soil erosion. The mean humus loss for these profiles is 36.3 t/ha for 100 years of simulation.

Published: December 2021

The present study is focused on a volcanic mountain area of Maramures (Gutai Mountains) with specific vegetation that requires identification and analysis. The flora of these meadows has a natural character. The phytosociological study was performed and there was found vegetal associations belonging to classesÂ Nardo - Callunetea Prsg. 1949, Molinio - Arrhenatheretea R. Tx. 1937 andÂ Vaccinio-Piceetea Br.-Bl. in Br.-Bl. et al. 1939. The revealing species of the associations indicate a relatively poor floristic composition; great coverage hasÂ Nardus stricta, mainly due to acid substrate and to the bryophytes layer developed. Each vegetal association is described by analysis of the bioforms, of the floristic elements, geoelements, ecological indices and economic value. In all the vegetal associations hemicryptophytes exceeds other categories of bioforms, and considering the geoelements, the greatest rate is held by the Eurasian elements. From the point of view of the ecological character prevails mesophilic plants, micro-mesotherms and euritherms, euriionics and acidophilus. Meadows have a very low nutritive value and a low productivity, especially because of excessive grazing. Mosaic distribution of phytocoenosis is due to the uneven distribution of the climatic factors depending on the exhibition and on the degree of slope inclination.

Published: December 2021

Frankliniella occidentalisÂ Â (Pergande) (Thysanoptera: Thripidae) is an important pest in vegetable and ornamental greenhouse crops due their direct damage by feeding and indirect damage by vectoring Tomato Spotted Wilt Virus (TSWV). Also, is very well known that they have an extremely high resistance to a wide range of insecticide. Thus by monitoring thrips population appropriate control plans can be established. Western flower thrips was reported in all greenhouses from Cluj County (Romania). In order to assess thrips population dynamic and color preference we conducted a research in a plastic greenhouse of 8000 mÂ 2 placed outside of Cluj-Napoca where the main cultivated crops were tomatoes (Â Solanum lycopersicum ) and the main thrips pest found was western flower thirps. During the sample period pest population was monitored weekly using two methods: by counting thrips trapped on five different colored sticky cards (blue, yellow, white, red and transparent) and by a technique based on leaves tapping. Data analysis showed no correlation between traps and tapping method. Blue and yellow traps had the highest attractiveness compared with all the others colors and between those, blue proved to be the most effective.

Published: December 2021

.Â Â In the experimental field of UASVM Cluj-Napoca from Jucu we performed, between 2008- 2010, a series of research on the behavior of eight varieties of marigold, in three conditions of soil fertilization with manure. Marigold experimental variants were established by direct seeding by hand, at a distance of 70 cm between rows. Each cultivar was sown in four repetitions, each 25 sqm. The annual average air temperature in Jucu was 10.71Âº C in 2008, 11.12Âº C in 2009 and 11.21Âº C in 2010. In terms of rainfall, 2008 was very dry, 2009 excessively dry and 2010 was very wet. Climatic conditions were favorable for growing marigolds. Economic efficiency indicators were calculated to reveal the effectiveness of soil fertilization with organic fertilizers and value the tested cultivars, in terms of production. Economic efficiency calculation was performed using marigold yields obtained in 2008-2010 in the three agrofunds (F0, F20 and F40). There were dried marigoldâ€™s flower productions between 1.042 and 1Â .700 kg / ha. The highest yields were obtained in 2008, when climatic conditions were more favorable than in other years. The greatest net profit (average 2008 - 2010) was obtained by cultivation of Belezza del Pacifico (3.69 thousands lei/ha), followed by Cluj 2 (3.65 thousands lei/ha) and Starsem 922 (3.50 thousands lei/ha).

Revolution, especially in science, will always be regarded with anxiety because nothing can be more terrible than the fear of a creative mind to see, after years in which he painstakingly built and effort building your own system, placed the foundation of what was thought to be granite truth, that a heretic, came amiss, it looks like a mysterious magician, his certainty that the stone was just an illusion, a disguised form of nothingness. In saying this, to reach a truly exceptional, postulated by Romanian and universal whileÂ Nicholas Georgescu - Roegen , a vision which alone would be enough to put this so little known, however, thinker, the genius category. It isÂ the distinction between growth and developmentÂ Â Â , two words so often confused and sometimes used in theory and practice of economic thought. It essentially says N. Georgescu - Roegen - in the footsteps of his master's from Harvard, Joseph A. Schumpeter, "Â growth is to produce more, develop, produce different ". Dominated by the idea of perpetual accumulation, mankind has been for centuries and longer still, in constant pursuit for the "more", without understanding the truth that, in fact, natural purpose is "to be" in a context of quality - and morally - superior. Escape the trap of this "more", with its subsidiary "faster" as a solution to living better and more complete quality is necessary and possible. The starting point in bio-economic theory of N. Georgescu - Roegen was the finding that the survival of mankind has a problem entirely different from that of other species is neither exclusively biological nor exclusively economic: is bio-economic characteristics and traits depend on many asymmetries that exist between the three sources of entropy which together form the heritage of humanity - free energy, received from the sun, on the one hand, and free energy and materials ordered structures hidden in the bowels of the earth, on the other.Â Systems bio-economic farming involves all elements: water, air, soil, climate, plants, animals, etc., creating natural products, whether we call organic, biological, organic, etc.. Development and use growing as scientific knowledge, research, emphasizes rationality in economic activity, thus ensuring the premise to increase economic efficiency in bio-economic conditions.

The research in the period 2010-2011, within the Ezareni Farm from Iasi, were focused on the influence of inoculation, fertilization and harvesting growth stage on the leaf/shoot ratio and dry matter (DM) yield, at alfalfa (Â medicago sativa L.) in the second year after sowing at the first harvest. The results indicated that the interaction between inoculation, fertilization and harvesting growth stage determined increases of yield in the range of 23-110%. The control plot where fertilization was not applied, without inoculation, which was harvested at early bud registered the lowest yield, 3.21 t/ha D.M., and the biggest yield (6.72 t/ha) was registered at the plot with inoculation, fertilized with NÂ 75P50, harvested at 10% blooming. The leaves/shoots ratio registered differences in the range of +11% to -42%, accordingly to the interaction between the inoculation, fertilization and harvesting growth stage. The highest leaves/shoots ratio, 0.64% was observed at the plot with inoculation, unfertilized, harvested late bloom, and the lowest leaves/shoots ratio (0.33) was observed at the plot without inoculation, fertilized with NÂ 75P50 harvested at full bloom.

The pasture of Åžurdești villageÂ is situated in the north-west of Maramures County, at 600- 900 meters altitude, on slightly sloped soils (5-30Â 0). The present study aims to research the preferences of the species of a vegetal association,Â Festuco rubrae - Agrostietum capillaris Horvat 1951, for the main environmental factors: humidity (U), air temperature (T), and soil reaction (R). The analysis of ecological groups contributes to a better understanding of the adaptive and evolutionary process of plant communities in relation to environmental factors. The ecological characteristics of the plant association will be explained according to pedoclimatic conditions and based on the analysis of the response of species to the environment condition, in order to take corrective measures for agricultuÂ reâ€™s improvement. The floristic composition is large (74 species) in 10 relevÃ© analyzed. The ecological spectrum emphasizes a dominance of mesophilic species (37.84%) in the vegetal association. Reported to the heat index there are micro-mesothermal plants (43.24%), followed by amphitolerant species 37.84%, and reported to the chemical reactions in the soil euriionic species (56.76%) to weak acid-neutrophil species (16.22%) are distinguished. In the Romanian Carpathians the meadows withÂ Festuca rubra and Agrostis capillaris have a wide spread, with

Gray mould fungus,Â Botrytis cinerea is a plant pathogenic fungus with an extensive host range that causes damage to a wide range of crops including vegetables, soft fruit, ornamental plants and grapevines. Control of fungal diseases is a key problem in agriculture worldwide. To develop effective controls for this gray mould, various characteristics ofÂ Botrytis cinerea Pers., such as its life cycle and mode of infection, must be determined. Epidemiological studies are difficult because of the genetic and phenotypic variability within this species. Under this consideration the purpose of our study was the observation of the fungus cultural and morphological characteristics but also the testing of the antifungal effect of some plant hydroalcoholic extract.Â In our experiments weâ€™ve identified and isolated the pathogenÂ Botrytis cinerea Pers., inoculated it on three culture media and we observed the growth rate of the colonies, the sporulation and sclerotia appearance, the shapes and the dimensions of conidia, the number and distribution of the sclerotia. The different extracts in three different concentrations were teÂ sted in 80 mm diameter Petri plates incubated at 25ÂºC and assessed after three, six and nine days of incubation. Plates were examined for the presence or the absence of the colony growth and the diameters of the colonies were measured establishing the colony area and the inhibition percent of the tested plant extracts.

The aspects of external morphology in theÂ Monarthopalpus buxi species (Rubsaamen) - (Diptera: Cecidomyiidae) are important in recognizing and distinguishing this species among other pests, and then in establishing strategies for prevention and fight against this pest. With the purpose of studying morphological aspects, the biological material, that is eggs, larvae, chrysalis, adults, has been collected from theÂ Buxus serpenvirens bushes considered for the study. The biological material has been collected on the leaves (egg, larva, adult), whilst the chrysalis from the interior of the leaf, nearby the median nervure, with the help of utensils (brushes, bolds, spatula, scalpel, scissors). The adults have been captured with the help of colored panels and a brush with 70% alcohol, on leaves, and then introduced in sterile test-tubes with 70% alcohol, and ultimately brought in the laboratory for photos. The eggs and larvae have been collected directly on leaves; three small branches have been collected from each bush and brought in the laboratory for photos within one hour. The chrysalis has been collected from the interior of the leaf; 10 leaves have been collected from eachÂ Buxus serpenvirens bush considered for the study, and dissected in the laboratory with the help of two entomological bolds, and then photographed. The photos have been made in the laboratory, at the University of Agricultural and Veterinary Sciences in Cluj-Napoca, with a binocular magnifying-glass type Motic (Szm-143, Input 220-240 Vac) and a Sony (Zeiss-Carl, 7,2 Mega pixel, Full Hd-1080) camera.

In this paper we present results of the research made between 2008-2010 on the effectiveness of soil fertilization with organic fertilizers and value cultivars tested, in terms of production. Experiences had been located in the experimental field of Jucu, CJ. We took four cultivation of artichokesÂ in the study: â€œUnireaâ€, â€œVioletâ€, â€œAgrosel 656â€ and â€œChișnÄƒâ€. They were placed in the experimental field of Jucu - Cluj, made in two densities (3.57 pl/sqm and 2.38 pl/sqm) and three levels of fertilization (unfertilized, fertilized with 20 t/ha farmyard manure and 40 t/ha manure in the fall plowing). The sowing was performed manually in the artichokes nests (2-3 seeds/nest). The experience was located in four repetitions of 10 sqm. Biometric measurements were conducted at 10 plants in each plot experimental environments. Harvesting has been done manually with a sickle. Economic efficiency was established by calculating the following economic indicators: production per hectare achieved, value of trading, average price recovery, cost of production, cost per unit of product, taxable profit, net income + grants, rate is expressed as %, net profit + subsidy rate. From the cultivars studied, the highest net profit was obtained in cultivation Unirea (8,976 lei/ha), followed by far by the Purple (6,745 lei/ha). The main driver of profit was due to the production of plant material. From the three agrofunds, the ones fertilized with 40 t / ha manure turned out to be the most economically efficient of all cultivars due to higher production per hectare.
Tourism Globalisation in Todays European Context

Modern society is in a transition process towards a global civilization. Economic and social phenomena such as internationalization of production, unprecedented intensification of international trade, forming global markets for finance capital, polarization of the population in rich and poor, exhaustion of the resources and degradation of the environment are a few main topics of the globalization. This should be seen as a natural process (primarily determined by modern technology), affecting the whole society, from organizations to state entities or to transnational interest groups. Thus, the globalization phenomena represents "... the integration of global markets (goods, services and capital) and technologies, increasing interdependent relationships at transcontinental scale ..." One of the most important objectives of this European "force" is creating a common market, an objective enshrined in the Treaty of Rome, since 1958, aiming to increase the economic prosperity of the Member States by at least two levers: free trade and free competition. Thus, EU rules cover all aspects of such a market, such as competition, taxation, industrial policies, transport, agriculture, etc.., and of course tourism. In this context, privatization, deregulation and liberalization of the service sector and the prices and international trade services, have created the way to achieve the globalization process in the tourism sector, which began with the cooperation of major hotel chains and airlines booking international locations the transport and accommodation.
