Estimating leaf appearance rate and phyllochron in safflower (Carthamus tinctorius L.)
Streck, Nereu Augusto;Bellé, Rogério Antonio;Rocha, Edileusa Kersting da;Schuh, Mariangela;

Abstract: safflower may be an interesting option for the flower market, either as fresh or dried cut flower. estimating the leaf appearance rate and the phyllochron (the time interval between the appearance of successive leaves) is important for calculating the number of emerged leaves (nl) on the plant, which is an excellent measure of plant development. the objective of this study was to estimate the leaf appearance rate and the phyllochron in safflower (carthamus tinctorius l.). an experiment was conducted in santa maria, rs, brazil, inside an 8 x 15m plastic greenhouse. sowing was on 03 october 2003 and emergence was on 08 october 2003. the experimental design was a randomized complete block design with three replications. the main stem nl was measured twice a week from 24 october 2003 to 15 november 2003 in four plants per replication. daily growing degree days above a base temperature (5°c) and accumulated thermal time (tt) were calculated. the nl was linearly regressed against tt. the angular coefficient of the linear regression is the lar (leaves/ °c day) and the phyllochron (°c days/leaf) was estimated by the inverse of the angular coefficient of the linear regression. the lar was 0.0467 ± 0.0203 leaves/ °c day and the phyllochron was 25.5 ± 14.6°c days/leaf.

Daily growing degree days above a base temperature (5degreesC) and accumulated thermal time (TT) were calculated. The NL was linearly regressed against TT. The angular coefficient of the linear regression is the LAR (leaves/ degreesC day) and the phyllochron (degreesC days/leaf) was estimated by the inverse of the angular coefficient of the linear regression. The LAR was 0.0467 ? 0.0203 leaves/ degreesC day and the phyllochron was 25.5 ? 14.6degreesC days/leaf.

Abstract: this paper portrays a study about the use of the internet research by graduate students at universidade federal de mato grosso/campus universitário de rondonópolis. it aims to verify whether the students present any kind of difficulties during their research. in order to develop this research, it is necessary that the research be efficient when it comes to search strategies. there are several ways to develop a relevant research; among them there is the use of booleans, which filter important information about the desired topic. there are several explanations about research in general, web research, search mechanisms, research filters, and librarian role. a questionnaire about access and use of available information on the internet was applied to the students as a way to get data. it was concluded that graduate students use the internet to do their academic papers, although they have difficulties with the back up of information, since some pieces of information found on the web are not consistent, or because there is a lack of support and orientation to get information through filters.

Abstract: white mold caused by sclerotinia sclerotiorum may severely damage vegetables grown in greenhouses. to develop a biological control program for this pathogen proper antagonists are needed. this work aimed to select efficient fungi antagonists for controlling s. sclerotiorum on cucumber (cucumis sativus) grown in greenhouses, and to evaluate the effect of the antagonist on the growth of the vegetable. an isolate of s. sclerotiorum obtained from cucumber and 112 fungi isolates belonging to four genera were used: trichoderma, fusarium, penicillium, and aspergillus. for the in vitro experiment, the cellophane method was used and eight trichoderma virens isolates were selected that had inhibited the pathogen growth by 94 to 100%. greenhouse experiments used sterilized and non-sterilized substrate in plastic cups and non-sterilized substrate in plastic bags. the substrate was inoculated with s. sclerotiorum and the eight isolates of t. virens were used as antagonists. all eight isolates controlled damping-off of plants caused by s. sclerotiorum, but the effect on cucumber growth varied according to the isolate and the substrate treatment.

Où sont les paysages rwandais ? Paysagenèse : un regard postcolonial
Philippe Kersting
Trajectoires , 2010,
Abstract: Cet article propose d’appliquer le potentiel critique et déconstructiviste du concept de l’ethnogenèse au concept de la Landschaftsgenese (paysagenèse), lequel est issu d’une géographie physique objectiviste et rationaliste. Une approche postcoloniale montre que les paysages rwandais, qu’ils soient précoloniaux, coloniaux ou postcoloniaux, sont toujours l’enjeu de processus de colonisation réelles et imaginaires. Der vorliegende Aufsatz schl gt eine Anwendung des kritischen und dekonstruktivistischen Potentials des Konzepts der Ethnogenese auf das Konzept der Landschaftsgenese vor, welches einer objektivistischen und rationalistischen Geographie entnommen ist. Ein postkolonialer Zugang verdeutlicht, dass die ruandischen Landschaften, seien sie vorkolonial, kolonial oder postkolonial, stets Gegenstand realer und imagin rer Kolonisationsprozesse sind.

Voting Behaviour in the 2009 South African Election W hlerverhalten bei den südafrikanischen Wahlen von 2009
Norbert Kersting
Africa Spectrum , 2009,
Abstract: This article analyses voting behaviour in the South African election of 2009 and draws conclusions regarding the significance of party affiliation and issue-based voting in South Africa. It demonstrates the low level of voter registration and voter turnout. In the 2009 election the Independent Electoral Commission had problems with electoral management for the first time; however, it was able to prevent electoral violence. During the campaign the newly founded COPE focused on institutional reforms and the oppositional Democratic Alliance concentrated too much on negative campaigning. In the post-Mbeki era, the ANC has been able to reinvent itself by being the only party with a strong focus on pro-poor policies. Nevertheless, the lack of alternatives in electoral democracies may lead to alternative instruments of political action. Der Autor analysiert das Verhalten der W hler bei den Wahlen in Südafrika 2009 und zieht daraus Schlüsse auf die relative Bedeutung der Parteizugeh rigkeit beziehungsweise von inhaltlichen politischen Aussagen der Parteien. Deutlich werden der niedrige Anteil registrierter W hler und die geringe Wahlbeteiligung. Die Unabh ngige Wahlkommission hatte zum ersten Mal Probleme mit der Organisation der Wahlen, konnte aber gewaltsame Auseinandersetzungen verhindern. W hrend der Wahlkampagne konzentrierte sich die neu gegründete Partei COPE auf Forderungen nach institutionellen Reformen, w hrend die oppositionelle Democratic Alliance einen stark defensiven Wahlkampf führte. Demgegenüber gelang es dem ANC in der ra nach Mbeki, sich erneut als einzige Partei zu profilieren, die eine Politik zugunsten Armer verfolgt. Allerdings kann der Mangel an politischen Handlungsm glichkeiten in Parteiensystemen dazu führen, dass künftig st rker auf alternative Instrumente politischer Aktion gesetzt wird.
Potência de a o e ordem: o poder e a raz o segundo Nicolau Maquiavel e Thomas Hobbes
Kersting, Wolfgang
Veritas , 2006,
Abstract: O autor apresenta aborda, primeiramente, a rela o entre poder e raz o no pensamento político de Maquiavel. Num segundo momento, apresenta, no pensamento de Hobbes, a trajetória que se estende da raz o impotente do estado de natureza até à raz o poderosa do Estado, dispensador de seguran a. The author analyses in a first moment the relationship between power and reason in the political thought of Machiavelli. In a second moment, he exposes, according to Hobbes’s political philosophy, the path to be gone through from the powerless reason of the state of nature towards the powerful reason of the State, which grants security.
Gewichtiges Dokument eines jungen Wissenschaftszweiges An important document in a young field of study
Christa Kersting
querelles-net , 2005,
Abstract: Das vorliegende Handbuch verschafft einen soliden überblick über den aktuellen Forschungsstand in Theorie, Geschichte, den Handlungsfeldern und Methoden einer aus der Genderperspektive konzipierten Erziehungswissenschaft. In den unterschiedlichen Ann herungen an Geschlecht“ spiegelt es den konfliktreichen Forschungsprozess wider und eignet sich als Grundlage für Forschung und Lehre in diesem Wissenschaftsfeld. This handbook offers a well-founded overview over current research in theory, history, topics and methods of a gender-oriented pedagogy. The book is well suited to be used as a basis for research and teaching in this area of field, since it mirrors the different and conflict-laden stages of research by taking different approaches to “gender”.
