Weeds can cause damages to economic crops by competition for water, light and nutrients in cultivated areas. This work aimed to evaluate maize yield and weeds population after green manures cultivation. The experiment was conducted in an Ultisol, placed at Integrated System of Agroecological Production, in Serop?dica, RJ, from October 2014 to June 2015. The experimental design was of randomized blocks, with six treatments and four replications. The treatments involved previous cultivation with sunnhemp (Crotalaria juncea), jack bean (Canavalia ensiformis), velvet bean (Mucuna aterrima), sunflower (Helianthus annuus), sorghum (Sorghum bicolor), and fallow. The green manures were sowed in October, being cultivated during 113 days after sowing. After that, they were cut. Five days after the cut and deposition of the green manures residues in the soil surface, it was sowed maize var. Caatingueiro, adopting spacing of 1,0 m between lines and density of five seeds per linear meter, with a population of 50.000 plants per hectare. Weeds population was evaluated at 15, 30, 45, and 60 days after maize sowing, collecting samples of weeds for identification and quantification of species, and dry biomass production. The obtained data were used for determining of phytosocial indexes. Dry biomass of green manures was greater for the treatments sunnhemp and sorghum. On the other hand, dry biomass of weeds was greater in the treatment velvet bean. Yield of maize without straw; yield of shoot biomass; diameter, length and N contents in grains and shoot did not show significant differences between treatments. Weeds population compositions is influenced by the soil cover crops. The use of sorghum was efficient regarding to biomass production and weeds control. Sunnhemp and sorghum produced biomass values above the recommended amounts for no-tillage system. / Em sistemas org?nicos de produ??o, a aduba??o verde e o uso de cobertura morta s?o recomendados, de forma a manter ou recuperar a fertilidade dos solos e promover a ciclagem de nutrientes, al?m de manejar a popula??o de plantas espont?neas. Esp?cies espont?neas podem causar preju?zos ?s culturas de interesse econ?mico, o que pode ser explicado pela competi??o por ?gua, luz e nutrientes nas ?reas cultivadas. Objetivou-se nesse trabalho avaliar o desempenho agron?mico de milho verde e a din?mica populacional de plantas espont?neas ap?s cultivo de adubos verdes. O experimento foi realizado em um Planossolo, localizado no Sistema Integrado de Produ??o Agroecol?gica, no munic?pio de Serop?dica, RJ, no per?odo de outubro de 2014 a junho de 2015. O delineamento experimental adotado foi de blocos casualizados, com seis tratamentos e quatro repeti??es. Os tratamentos constaram de cultivo pr?vio de crotal?ria (Crotalaria juncea), feij?o de porco (Canavalia ensiformis), mucuna preta (Mucuna aterrima), girassol (Helianthus annuus), sorgo (Sorghum bicolor) e pousio com vegeta??o espont?nea. A semeadura dos adubos verdes foi realizada no m?s de outubro e seu cultivo se deu at? os 113 dias ap?s a semeadura, realizando-se ent?o sua ro?ada. Cinco dias ap?s a ro?ada e deposi??o dos res?duos culturais ao solo, foi realizada semeadura direta do milho variedade Caatingueiro, com espa?amento de 1,0 m entre linhas e densidade de cinco sementes por m-1 linear, totalizando 50.000 plantas por hectare. A popula??o das plantas espont?neas foi avaliada aos 15, 30, 45 e 60 dias ap?s o plantio do milho, atrav?s da coleta de amostras da popula??o espont?nea para identifica??o e quantifica??o das esp?cies e da produ??o da biomassa seca. Os dados obtidos foram utilizados na determina??o de ?ndices fitossociol?gicos. A biomassa seca dos adubos verdes foi maior para os tratamentos crotal?ria e sorgo. Por sua vez, a biomassa seca das plantas espont?neas foi maior na presen?a da cobertura do solo com mucuna preta. Quanto ? produtividade de espigas despalhadas, produtividade de biomassa a?rea do milho, di?metro, comprimento e teores de N no gr?o e na parte a?rea, n?o houve diferen?a significativa entre os tratamentos. A popula??o de plantas espont?neas foi influenciada em sua composi??o, em fun??o dos adubos verdes cultivados. A cobertura com sorgo mostrou-se eficiente quanto ? produ??o de biomassa vegetal e controle de plantas espont?neas. A crotal?ria e o sorgo atingiram quantidade de biomassa acima da recomendada para adequada implanta??o do sistema plantio direto.

No. of bitstreams: 1 2016 - Tiago de Andrade Chaves.pdf: 554789 bytes, checksum: 8b331ddf709ed404e7783dcae1b07269 (MD5) Previous issue date: 2016-08-25 / In rural areas the native forest fragments and the presence of the tree element can provide many ecosystem services to the population and the productive system. However, due to the small size of the properties of small producers in the state of Rio de Janeiro, linked to the fear of losing production areas with the introduction of trees not always this element is part of the system. One of the strategies found for the introduction of tree species in production systems is the use of it as a hedge. The objective of this study was to test the cutting propagation of multifunctional forest species with potential for use as a living fence. It was assessed that the best position in the branch, apex or base and the use of nut grass extract in the rooting of cuttings of Schinus terebinthifolius, Gliricidia sepium, Croton urucurana, Trema micranta, Pouteria caimito and Casearia sylvestris. The vegetative propagules were immersed in distilled water or immersed in solution extract of C. rotundus tubers. We evaluated the number and size of buds, budding rate, shoot dry weight, rooting rate, root number, size of the largest root, root dry weight and survival rate. The species G. sepium, S. terebinthifolius and T. micranta presented rooting rate of 17.5%, 7.5% and 2.5%, respectively. The other did not send roots. As for the position in the branch, only 5% of apical cuttings of S. terebinthifolius issued roots. The highest rates were found budding in S. terebinthifolius (47.5%), G. sepium (27.5%), C. sylvestris (22.5%) and T. micranta (2.5%). The use of C. rotundus extract showed significant difference in the number of shoots of basal cuttings of G. sepium, but had no effect on rooting. Only G. sepium showed potential for reproduction by cuttings. The use of cuttings obtained from the base of the branches were more efficient in propagation of forest species. The use of fitoregulador not influenced rooting, however, showed potential in boosting the number of shoots in basal cuttings of G. sepium / Na ?rea rural os fragmentos de mata nativa e a presen?a do elemento arb?reo podem fornecer diversos servi?os ecossist?micos ? popula??o e ao sistema produtivo. Por?m, em consequ?ncia ao reduzido tamanho das propriedades dos pequenos produtores do estado do Rio de Janeiro, associado ao receio de perder ?reas de produ??o com a introdu??o das ?rvores, nem sempre este elemento faz parte do sistema produtivo. Uma das estrat?gias encontradas para agregar esp?cies arb?reas aos sistemas produtivos ? o uso das mesmas como cerca viva. O objetivo deste trabalho foi testar a propaga??o por estaquia de esp?cies florestais multifuncionais com potencial para uso como cerca viva. Foi avaliada qual a melhor posi??o do ramo, ?pice ou base e o uso do extrato de Cyperus rotundus sobre o enraizamento das estacas de Schinus terebinthifolius, Gliric?dia sepium, Croton urucurana, Trema micranta, Pouteria caimito e Casearia sylvestris. Os prop?gulos vegetativos foram imersos em ?gua destilada ou imersos em solu??o com 50% de ?gua destilada e 50 % de extrato de tub?rculos de C. rotundus. Foram avaliados o n?mero e tamanho dos brotos, taxa de brota??o, mat?ria seca de parte a?rea, taxa de enraizamento, n?mero de ra?zes prim?rias, tamanho da maior raiz, mat?ria seca de raiz e taxa de sobreviv?ncia. As esp?cies G. sepium, S. terebinthifolius e T. micranta apresentaram taxa de enraizamento de 17,5%, 7,5% e 2,5%, respectivamente. As demais n?o emitiram ra?zes. Quanto ? posi??o no ramo, somente 5% das estacas apicais de S. terebinthifolius emitiram ra?zes. As maiores taxas de brota??o foram encontradas em S. terebinthifolius (47,5%), G. sepium (27,5%), C. sylvestris (22,5%) e T. micranta (2,5 %). O uso do extrato de C. rotundus mostrou diferen?a significativa no n?mero de brotos das estacas basais de G. sepium, mas n?o apresentou influ?ncia no enraizamento. Nas condi??es avaliadas apenas a G. sepium apresentou potencial para a reprodu??o por estaquia. O uso de estacas obtidas a partir da base dos ramos mostraram-se mais eficientes na propaga??o das esp?cies florestais. O uso do fitoregulador n?o influenciou o enraizamento, no entanto, mostrou potencial no est?mulo do n?mero de brota??es nas estacas basais de G. sepium

Integrating pragmatic competence in teaching English to the students of medicine at Taiz University / Intégrer la compétence pragmatique dans l’enseignement de l'anglais aux étudiants de médecine de l'Université de Taiz

Al-Aghbari, Diana 29 September 2016 (has links)
L'un des objectifs de l'enseignement d'une langue est de rendre les apprenants conscients de la façon d'utiliser cette langue en fonction de leurs objectifs communicationnels. Cette compétence relève du champ de la pragmatique. Cette recherche porte sur l'enseignement de la pragmatique dans un contexte d’Anglais de Spécialité (ASP), à savoir la Faculté de médecine à l'Université de Taiz. Elle étudie le niveau de compétence pragmatique chez les étudiants en médecine dans le but de l’intégrer dans la salle de classe. L'étude fait appel à une enquête par questionnaire composé de “Discourse Completion Tasks” afin d'examiner la capacité des étudiants à produire des actes de langage, et d’un test de conscience visant à mesurer leur capacité à identifier les énoncés appropriés et inappropriés. L'interview est un autre outil que nous avons conçu pour explorer les perceptions des étudiants diplômés envers la compétence pragmatique. Une approche qualitative et quantitative est adoptée pour l’analyse des données. Les résultats de l'étude montrent que les étudiants ont un niveau de compétence pragmatique faible en ce qui concerne la production et aussi la conscience pragmatique. De plus, les étudiants ont fait preuve d'une réceptivité accrue quant à l'importance de la compétence pragmatique. Par conséquent, un modèle provisoire est proposé pour favoriser l’intégration de cette compétence en ayant recours à une série télévisée qui pourrait les motiver à apprendre l'anglais. / One of the goals of teaching a language is to make learners aware of how to use it to serve a communicative purpose. This lies within the scope of pragmatic competence. This research deals with teaching pragmatics in a context of English for Specific Purposes (ESP), namely the faculty of medicine at Taiz University. It investigates medical students’ level of pragmatic competence with the ultimate aim of integrating it in the classroom. The study makes use of a questionnaire composed of a Discourse Completion Task to examine students’ ability to produce speech acts and an awareness test to measure their ability to identify appropriate and inappropriate utterances. The other tool is an interview conducted to explore graduate students’ perceptions towards pragmatic competence. The data are analysed qualitatively and quantitatively. The study findings reveal a low level of pragmatic competence among students in the production and awareness levels. Besides, a positive tendency is shown towards the importance of pragmatic competence. Accordingly, a tentative model is proposed to incorporate pragmatic competence with the help of a medical TV show which will keep them motivated in learning English.

ELT teaching quality and practice in Saudi Arabia : a case study of the perspectives of ESP and EGP students, teachers and managers at the ELC in Umm al-Qura University

Melibari, Ghader January 2016 (has links)
In recent years EFL education within Saudi Arabia has come under increased scrutiny, due to government efforts to reform the broader education system within the country, and the perceived importance of English as a global language of commerce and enterprise. EFL education within Saudi Arabia suffers from a number of problems, including low standards and a tendency within the Saudi education system to rely upon prescriptive and authoritarian teaching paradigms. In addition to this, there is no cohesive national strategy for EFL teacher training and education, and little emphasis on professional development opportunities for teachers within the EFL field. This study focuses attention on EFL teacher quality within Saudi Arabia as a critical component in improving English language education across the country. The study presents a case study of Umm al-Qura University, in Mecca, Saudi Arabia, in which the perspectives of students, teachers and managers were explored in depth in order to shed light on the current mechanisms for ensuring teaching quality in EFL. Adopting a mixed-methods approach, the study engaged in an in-depth case study of the English Language Centre (ELC) at the Umm al-Qura University. A quantitative questionnaire was distributed to students within the ELC, and semi-structured interviews were undertaken with teachers and academic managers, in addition to classroom observations conducted by the researcher. The findings corroborated recent research on educational paradigms within Saudi Arabia, and highlighted a number of cultural factors that impacted upon teacher quality within the ELC. The findings of the study form the basis of a series of recommendations for improving English language teaching quality within the Kingdom of Saudi Arabia.

In Brazil there are registers in the Amazon region, Atlantic Forest and Caatinga from semi-arid region from Bahia, however nothing is know for other areas such as the Cerrado. Considered a genre of identification difficult due to the complex structure of the male terminalia, it was already confused with other genera of Psychodidae. Currently it is considered more closely related to Platyplastinx Enderlein, 1937. In the attempt to solve part of this problem, the present paper describes again Alepia and proposes a new diagnosis for Platyplastinx. 122 males specimes of Alepia and 8 of Platyplastinx were examined, besides of the type material of some species of Alepia deposited in the Cole??o Entomol?gica Prof. Johann Becker do Museu de Zoologia da Universidade Estadual de Feira de Santana, Bahia, Brazil (MZFS), as well as photographs of type material from international museums. Female specimens were not examined due to difficulties in association. The specimens were treated with 10% KOH, dehydrated, and mounted in permanent slides in Canada balsam, and their structures were photographed, illustrated and characterized. All the material will be deposited in the MZFS and in the Cole??o de Invertebrados do Instituto Nacional de Pesquisa da Amaz?nia, Amazonas, Brazil (INPA). 26 new species of Alepia and four of Platyplastinx are described. Platyplastinx obscura comb. n. is proposed. Two subgenera are created for Alepia (Xus subgen. n., Yus subgen. n.) and taxonomic comments are woven to five species of the genus (A. alcobregma Quate, 1999; A. amputonis Quate & Brown, 2004; A. distincta Bravo, Lago & Castro, 2004; A. eburna Rapp, 1945 and A. symmetrica Wagner & Hribar, 2004). A. maculipennis Bravo, Lago & Castro, 2004 is redescribed and are given three new records of Alepia to Brazil, and new records for some Brazilian states. Catalogs are also provided for the species of Alepia and of Platyplastinx, as well as identification keys to the males of these genera. With this paper, the number of known species of Alepia is elevated from 52 to 78, and of the Platyplastinx, from eight to 13. / Alepia Enderlein, 1937 possui distribui??o apenas na regi?o Neotropical e at? o presente momento s?o conhecidas 52 esp?cies, 20 destas para o Brasil.

Problematika znalecké analýzy jízdy a brzdění vozidla v obecném prostorovém oblouku při rychlostech vyšších než 50 km/h / Problems of the Expert Analysis of the Vehicle Movement and Braking Action in General Spatial Curve at Speed Higher than 50 km/h

Panáček, Vladimír January 2015 (has links)
The present apparatus for the technical analysis of road accidents has no well-integrated information, recommendations or procedures of how to solve comprehensively the analysis of road accidents involving vehicles equipped with stabilization system of driving dynamics. The problem in the investigation of a vehicle movement in a curve is the ignorance of the contributions of vehicle dynamics intervention of the electronic stability system. Although some of the simulation software used in the analysis of road accidents makes it possible to take into account the modelled vehicle movement impacted by a stabilization system in the examined process, but the experts do not know what parameters should be entered in the numerical models of stabilization system in a computer programme. Therefore, the thesis investigates the issue of the expert analysis of vehicle riding and braking in a general spatial curve at speeds exceeding 50 kph with simultaneous examining the impact of electronic stability system chassis on vehicle driving dynamics. The thesis first deals with the solutions based on classical analytical methods, then dwells on experimental measurements in real conditions on testing grounds and, finally, addresses the use of computer simulation software in expert practice. Nevertheless, it is important to realize that no computer simulation software can be an absolutely unambiguous solver, and it is not enough to generate a computer simulation, but so obtained results should be evaluated and justified technically. Road accident analyst needs to know the impact of vehicle electronic stability control systems on vehicle movement. The thesis investigated the mutual relationship between the vehicle speed limit in a curve specified by analytical calculation and the vehicle speed in a curve experimentally detected by measuring the parameters of driving dynamics of a vehicle equipped with electronic stability system. The impact of selected electronic stability control systems of the chassis on the vehicle movement in the investigated processes in the curve was detected and quantified by driving experiments. Finally, the input values of significant quantities of computational models of the ESP simulation programs were found consistent with the results of experimental measurements in defined curves for the vehicles equipped with electronic stability systems. The results of the thesis can be used both in the expert and in the teaching activities.

Untersuchung zur Verfügbarkeit von ESP in Pkw 2006: Unfallforschung kompakt

Gesamtverband der Deutschen Versicherungswirtschaft e. V. 22 April 2021 (has links)
Seit dem Jahr 1995 ist das Elektronische Stabilitäts-Programm (ESP) als Fahrerassistenzsystem (FAS) für Pkw verfügbar. In dieser Zeit hat ESP viele Menschenleben gerettet. Nach dem Sicherheitsgurt als „Lebensretter Nr. 2“ zwar anerkannt, ist ESP jedoch nach wie vor nicht serienmäßig in allen Pkw verfügbar. Die Unfallforschung der Versicherer (UDV) ist daher mit der vorliegenden Untersuchung der Frage nachgegangen, welche Neufahrzeuge aktuell mit ESP ausgestattet werden und wie hoch der Anteil der serienmäßigen ESP-Ausstattung ist. Diese Informationen sollen vor allem dem Verbraucher als Hilfe dienen für die Fahrzeug-Auswahl beim Neu- und Gebrauchtwagenkauf. Sie sollen aber auch Fahrzeug-Hersteller motivieren, ihre gesamte Fahrzeugflotte serienmäßig mit ESP auszustatten.

Untersuchung zur Verfügbarkeit von ESP in Pkw 2007: Unfallforschung kompakt

Gesamtverband der Deutschen Versicherungswirtschaft e. V. 22 April 2021 (has links)
Im Jahr 2006 hat die Unfallforschung der Versicherer (UDV) zum ersten Mal die Verfügbarkeit von ESP in Neufahrzeugen untersucht [1]. Sie ist dabei der Frage nachgegangen, welche neuen Pkw in Deutschland serienmäßig mit ESP ausgestattet werden und für welche Fahrzeuge ESP nur als Option oder gar nicht erhältlich ist. Die hier vorliegende Publikation stellt eine Aktualisierung dieser Untersuchung für das Jahr 2007 dar. Die Ergebnisse sollen vor allem dem Verbraucher als Hilfe dienen für die Fahrzeug-Auswahl beim Neuwagenkauf, sie sollen aber auch Fahrzeug-Hersteller motivieren, ihre gesamte Fahrzeugflotte serienmäßig mit ESP auszustatten. Eine Forderung, die die UDV seit langem vertritt.
