A COMPARATIVE STUDY OF BACTERIOSTATIC ACTIVITY OF SYNTHETIC HYDROXYLATED FLAVONOIDS BJM
Olivella,Mónica S.; Zarelli,Valeria E.P.; Pappano,Nora B.; Debattista,Nora B..
Among other properties, flavonoids present a notable bacteriostatic activity. In this paper, minimal inhibitory concentrations (MICs) of 5,7,4'-trihydroxyflavanone (naringenin), 5,7-dihydroxyflavone and 2',4',4- trihydroxychalcone (isoliquitirigenin) against Staphylococcus aureus ATCC 25 923 were determined and compared to values obtained for other chalcones and flavanones previously investigated. Specific growth rates and MICs were determined by a turbidimetric kinetic method. The observed sequence MICflavanone (inactive) >MIC7-hidroxyflavanone (197.6 µgml-1)>MIC5,7,4'-trihydroxyflavanone (120 µgml-1) showed that the introduction of an electron donating group (-OH) causes an increase in bioactivity. On the other hand, the comparisons...

A Comparison Of Condition Factor And Gonadosomatic Index Of Sardine Sardinops Sagax Stocks In The Northern And Southern Benguela Upwelling Ecosystems, 1984–1999 OceanDocs
Van der Lingen, C.D.; Kreiner, A.; Fréon, P..
Time-series of condition factor (CF) and gonadosomatic index (GSI) were generated using general linear models (GLM) for sardine Sardinops sagax stocks in the northern and southern Benguela ecosystems over the period 1984–1999. During this period the biomass of sardine in the northern Benguela remained at relatively low levels of <500 000 tons, whereas that of southern Benguela sardine increased 40-fold to 1.3 million tons. The GLMs explained 27 and 45% of the observed variation in CF, and 32 and 28% of the observed variation in GSI, for sardine in the northern and southern Benguela subsystems respectively. Whereas the sardine CF in the northern Benguela remained stable over time, that for the southern Benguela stock declined steadily during the study...

A COMPARISON OF CURRICULUM IN BACCALAUREATE DEGREE PROGRAMS IN AGRIBUSINESS MANAGEMENT AgEcon
Boland, Michael A.; Lehman, Erika; Stroade, Jeri L..
This research categorizes required and elective courses for 112 different 4-year baccalaureate programs in agribusiness management in the U.S. These included 50 degrees and 62 majors, options, or concentrations within degrees. Over 50% of the 50 degree programs do not require international and global dimensions of agriculture, and courses in management, marketing, or finance from the College of Business. Almost two-thirds of the 50 degree programs do not require an integrative course such as strategy.

A comparison of surface eddy kinetic energy and Reynolds stresses in the Gulf Stream and the Kuroshio Current systems from merged TOPEX/Poseidon and ERS-1/2 altimetric data ArchiMer
Ducet, N; Le Traon, Pierre-yves.
Analyses of surface eddy kinetic energy (EYE) inferred from 5 years of merged TOPEX/Poseidon and ERS-1/2 altimetric data are presented in the Gulf Stream (GS) and the Kuroshio (KS) Current systems, focusing on anisotropy and EKE seasonal, interannual, and long-term variations, as well as Reynolds stresses. For both GS and KS a descriptive analysis of the EKE field shows that it is anisotropic along the path of the currents and assesses the close relationship between the spatial distribution of EKE high levels and bottom topography. A striking ocean feature is found in the GS, shaped as a zonal "double-blade" structure in the EKE field, centered at 37 degrees N, 71.5 degrees W, that likely corresponds to a regular and permanent lateral displacement of the...

A complexa tarefa de educar a distância: uma reflexão sobre o processo educacional baseado na Web. Repositório Alice
ROMANI, L. A. S.; ROCHA, H. V. da.
Novas tecnologias de comunicação tornam-se a cada dia um meio mais rápido de acesso à informação, alterando vários segmentos da sociedade. Com isso, a Internet provocou um grande impacto em diversos setores, especialmente na educação com a promessa de construção de ambientes educacionais inovadores. No entanto, experiências de cursos a distância via rede têm apresentado resultados abaixo das expectativas com inúmeras situações frustrantes para professores e alunos. Neste artigo, discutimos o enfoque educacional e o futuro dos ambientes de educação a distancia baseados na Web, a partir dos resultados de uma pesquisa feita com professores e alunos de instituições brasileiras.

A COMPUTABLE GENERAL EQUILIBRIUM ANALYSIS OF MEXICO'S AGRICULTURAL POLICY REFORMS AgEcon
Harris, Rebecca Lee.
Since the late 1980s, Mexico has liberalized its agricultural sector, moving from a system of price supports, producer subsidies and consumer subsidies to a less distorting scheme in which market forces play a greater role. Coinciding with these agrarian and food policy reforms, the government has implemented the PROCAMPO system of direct payments to farmers. There is a general consensus that a direct payment program has the potential to be more efficient than a system of subsidies and supports. At the same time, there is widespread agreement that other policies need to be put in place to assure protection of the economically vulnerable segments of the population. Within this context, this paper uses a computable general equilibrium (CGE) model to analyze...

A CONTENT ANALYSIS OF SOURCE-MESSAGE HETEROGENEITY IN MASS MEDIA COVERAGE OF AGROBIOTECHNOLOGY AgEcon
Marks, Leonie A.; Kalaitzandonakes, Nicholas G.; Zakharova, Lucy.
In this paper, we use content analysis to examine the use of sources by US and UK newspaper reporters from 1990 to 1999. Positive (benefit) or negative (risk) messages are correlated with the "source" type in order to determine the degree of source-message heterogeneity in media reporting of agrobiotechnology.

A critical view to explanations for the maximal value of 50 % of genetic recombination RChHN
VALENZUELA,CARLOS Y; PÉREZ-ALZOLA,PATRICIA; SANTOS,MANUEL J.
The maximal value of 50 % of genetic recombination (RF = recombination fraction) between two linked gene loci has been explained by two models: (i) the restriction of crossovers to only two of the four chromatids of a tetrad (tetrad model); (ii) the limit of the occurrence of an odd number of crossovers between two loci, when the expected number of crossovers tends to infinite (odd-even model). This article shows that (i) is wrong. If tetrads were responsible for the maximal 50 % RF, sister chromatid exchanges (SCE) should display a maximal 100 % RF. In mammalian CHO cells we found that SCE yield a maximal 50 % recombination. Also, we demonstrated that the maximal 50 % RF for tetrads occurs because the sum of odd order coefficients in the binomial...

A DESCRIPTIVE ANALYSIS OF EMPLOYMENT TRENDS IN SOUTH AFRICAN AGRICULTURE AgEcon
Vink, Nick; Kirsten, Johann F..
The working paper discusses the trends in farm employment over time in South Africa. This is followed by the presentation of six case studies of specific commodities and regions with the view to establishing the potential employment effects of various changes in the policy environment. The article ends with an assessment of selected aspects of the wider environment within which the sector operates, to ascertain the extent to which such policy shifts are feasible, i.e. whether the measured effects in employment generation are likely to happen.

A DINÂMICA DAS MUDANÇAS EM UNIDADES DE PRODUÇÃO RURAL: ESTUDO COMPARATIVO NO MUNICÍPIO DE PATO BRANCO (PR) AgEcon
Lazzarotto, Joelsio Jose; Lima, Juvencio Braga de; Carvalho, Flaviana Andrade de Padua.
The process of organizational change constitutes a highly complex theme due to the a host of both internal and external organizational factors that may cause changes to be either facilitated or restricted. Such process, which may come as the result of a previuos planning or otherwise will also feature a varied amplitude which enables it to result in either incremented changes, when comprising but a few organizational features or strategical, if a large number of such components get reached by the process. Using these as a starting point we aimed at learning, simulating and analizing in a comparative way, the main changes in family agro-business production units in two distinct locations in the town of Pato Branco PR, which have shown to be contrastive...

A di-O-dihydrogeranylgeranyl glycerol from Thermococus S 557, a novel ether lipid, and likely intermediate in the biosynthesis of diethers in Archaea ArchiMer
Gonthier, Isabelle; Rager, Marie-noëlle; Metzger, Pierre; Guezennec, Jean; Largeau, Claude.
The lipids of a deep-sea hydrothermal vent arch ae on, Thermococcus S 557, were isolated, purified and structurally determined. Based on acid methanolysis and spectroscopic studies, the polar lipids were shown to comprise diphytanyl glycerol and dibiphytanyl diglycerol, typical membrane lipids of Arch aea. From the neutral lipids, 2,3-di-O-dihydro-14,15-geranylgeranyl glycerol was isolated. This novel ether lipid is, very likely, a close intermediate in the biosynthesis of diphytanyl glycerol diether in Arch aea.

A DISAGGREGATED TIME-SERIES ANALYSIS OF EXPORT-BASE MODELS: A CASE STUDY ON ELKO COUNTY OF NEVADA AgEcon
Banerjee, Swagata (Ban); Harris, Thomas R..
An important issue of debate in economic base literature is whether the export-base theory applies best to the short run, the long run, or both. An attempt is being made here in answering this crucial question by applying a two-step test for cointegration on quarterly employment data, and in gaining insights as to whether or not any unequivocal judgment can be made regarding the validity of the economic base hypothesis.
