Alterações morfológicas e citológicas do cafeeiro (Coffea arabica L, var. Bourbon (B. Rodr.) Choussy) cultivado em solução nutritiva decorrentes das deficiências e excessos dos macronutrientes

The present work was carried out in order to study: (1) the symptoms of deficiency and excess of macronutrients (N, P, K, Ca, S, Mg) in the coffee plant (Coffea arabica L. var. Mundo novo); (2) the modifications induced by those treatments in the hystological make up of the leaves; (3) the effects of deficiency and excess on the growth and in the chemical composition of the plants. Young coffee plants were grown in nutrient solution, three treatments being used, namely: complete solution (HOAGLAND & ARNON, 1950), deficient solution, in which a giVen element was omitted, and solution with 3 times the concentration of the element under study. The main conclusions can be summaryzed as follows. 1. SYMPTOMS. Clear cut symptoms of malnutrition were observed in the treatments: -N, -P, +P, -Ca, -Mg, -S and +S; the signals - and + stared respectively for deficient and excess level. 2. HISTOLOGICAL EFFECTS. The most definite alterations took place in the treatments +P, -Mg and +S. Usually the characteristics of the chloroplasts were affected: loss of the green color and coalescence into irregular bodies.

Estudos sôbre a alimentação mineral do cafeeiro. II: absorção do superfosfato radioativo pelo cafeeiro (Coffea arabica L., var. Bourbon Amarelo) em condições de campo

In order to find out the best way to supply phosphorus to coffee plants when growing in "terra roxa misturada", a red soil with a high fixing capacity, tagged superphosphate was applied by the following procedures: (1) topdressed in a circular strip around the trees; (2) placed in the bottom of a circular furrow 15 cm deep; (3) placed in a semicircular furrow also 15 cm deep; (4) sprayed directly to the leaves. In each case 150 gms. of ordinary superphosphate tagged with H3 P32 O4 to give 5 X 10(9) c.p.m. were given to the two and half year old coffee plants. It was found that for the several treatments of the total phosphorus in the leaves the following values, on a per cent basis, came from the applied superphosphates: (1) topdressed 10.2 per cent, (2) circular furrow 2.4 per cent, (3) semicircular furrow 1.7 per cent, (4) sprayed 38.0 per cent; one can see, then, that methods (2) and (3) commonly used by the coffee planters are a very inefficient way to supply phosphorus in this type of soil. The remarkable foliar absorption was checked twice: a water culture experiment was carried out, the radiophosphorus being supplied by brushing it in the upper and lower surfaces of a given leaf; radioactivity was detected all over the plant as a result both of absorption and translocation; on the other hand, leaves collected from the sprayed trees were radioautographed; the radioautographs showed the pattern of distribution of the P32 which indicates true absorption rather than a surface contamination. In another locality, an experiment was caried out with 8 year old plants growing in "arenito de Bauru" which is a sandy soil with much less phosphorus fixing capacity. In this experiment the aim was to compare absorption of tagged superphosphate by trees growin under mulch against plants not receiving this treatment, The uptake of phosphorus was the same for both sets of plants. In both field experiments soil samples down to 15 cm in the profile were collected and its 0.2NHC1 soluble phosphorus was counted; rather significant values were observed mainly in the upper 5 cm layers.

Estudos sôbre a alimentação mineral do cafeeiro, X: extração de macronutrientes na colheita pelas variedades "Mundo Novo", "Caturra" e "Bourbon Amarelo"

This paper deals with the determination of the content of macronutrients in pulp and beans of three coffee varieties, namely 'Mundo Novo', 'Caturra Amarelo' and 'Bourbon Amarelo'. Samples were collected in plantations located in the three types of soils herein most of S. Paulo, Brazil, coffee is grown, that is, "terra roxa legítima" (Ribeirão Preto), "massapé-salmourão" (Mocóca), and "arenito de Bauru" (Pindorama). The following main conclusions were drawn after statistical analysis of data obtained hereby. There is no statistical difference among the three varieties . Average contents of macronutrients, as per cent of the dry matter, are the following: N P K Ca Mg S bean 1,71 0,10 1,53 0,27 0,15 0,12 pulps 1.78 0,14 3,75 0,41 0,13 0,15 Samples collected in Mocóca ("massapé-salmourão") had lower N and K contents, probably due to lack of availability of these elements in the soil, as suggested by its analysis. Results obtained in this work are in good agreement with data described elsewhere. Out of the total of elements contained in the whole fruit the following proportions are exported as clean coffee: N - 2/3, P and K - 1/2, Ca, Mg and S - 1/3. It is clear therefore that a substantial amount of elements absorbed from the soil remains in the pulp or in the dry hulls which result from processing. From this fact raises the interest of using these residues as fertilizer in the coffee plantations.

Estudos sobre a alimentação mineral do cafeeiro: XIX. extração de micronutrientes na colheita pelas variedades "Mundo novo", "Caturra Amarelo" e "Bourbon Amarelo"

Foi determinado o teor de micronutrientes na casca (polpa) e no grão de café "cereja" das variedades "Caturra Amarelo", "Bourbon Amarelo" e "Mundo Novo" colhidos em plantas cultivadas em três tipos de solos - terra roxa legítima, massapé-salmourão e arenito de Bauru. A análise revelou que as três variedades possuem a mesma composição mineral com respeito aos elementos determinados. O tipo de solo - ou o local - influiu na composição das amostras. Em um saco de café em coco existem quantidades aproximadamente iguais dos elementos na casca e no grão.

Controle em pós-colheita das podridões da manga 'bourbon', conservada em câmara fria

Mangas 'Bourbon' foram conservadas em câmara fria, a temperatura de 10º C, tendo recebido previamente os seguintes tratamentos em pós-colheita: 1) controle; 2) imersão por 10' em água a 55 C; 3) imersão por 5' a 50 C em solução de Benomyl a 0,025% de p.a.; 4) imersão por 5' a 50ºC em solução de Benomyl a 0,050%; 5) imersão por 5' a 55ºC em solução de Benomyl a 0,025% de p.a. e 6) imersão por 5' a 55ºC em solução de Benomyl a 0,050% de p.a. Os resultados indicaram que todos os tratamentos, com exceção do controle, foram eficientes no controle da antracnose. Quanto à ocorrência das podridões moles, constatou-se perdas de 44, 36, 20, 20, 4 e 8% do primeiro para o sexto tratamento, respectivamente. Assim ficou evidenciado que os tratamentos à mais alta temperatura, conjugados ao fungicida Benomyl, foram aqueles mais interessantes no tratamento em pós-colheita de manga 'Bourbon' .

Le Protévangile de Jacques latin dans l'homélie Inquirendum est pour la fête de la Nativité de Marie

L'article est le fruit d'une recherche sur la survie du Protévangile de Jacques en latin. Il contient l'édition critique et la traduction d'une homélie pour la fête de la Nativité de Marie, désignée par son incipit, Inquirendum est, et conservant les ch. 1-8 du Protévangile de Jacques (PJ). Dans trois des six manuscrits utilisés pour l'édition, l'homélie fait partie d'un recueil de sermons de l'époque carolingienne, l'« Homéliaire de Saint-Père de Chartres ». Elle a été composée en même temps que cet homéliaire, entre 820 et 950, dans un milieu marqué par des échanges entre l'Angleterre et la France. L'auteur de l'homélie a inséré dans un cadre homilétique les ch. 1-8 du PJ. Il a utilisé une version latine amplifiée du Protévangile (traduction II), dont dépendent également plusieurs autres témoins: le manuscrit de Paris, Sainte-Geneviève 2787 (PJlatG); les Latin Infancy Gospels édités par M. R. James (JAr et JHer, formes Arundel et Hereford de la « compilation J »); le récit irlandais de l'enfance du Liber Flavus Fergusiorum (InfLFF). Certaines amplifications du récit primitif sont présentes dans l'ensemble de ces témoins, comme l'épisode de la révélation céleste du nom de Marie (traduction IIa). D'autres sont communes à l'homélie, à JAr-JHer et/ou à InfLFF, comme l'ordre supplémentaire donné par Joachim à ses bergers (traduction IIb). A côté de ces éléments traditionnels, l'article met en évidence une série de particularités rédactionnelles (omissions, retouches, additions). L'auteur de l'homélie tient notamment à souligner le caractère naturel de la conception de Marie.

Als Marie Bonaparte sich taub stellte ...

Between 1927 and 1931 Marie Bonaparte had herself operated upon her clitoris three times. She did so against Freud's advice with whom she was in analysis. Among psychoanalysts these operations are still often regarded as "errors" or aberrations. But for Marie Bonaparte, who was in various ways familiar with physics and a somatic approach, surgery was the first choice, psychoanalysis only a possible alternative. She was not impressed by the skepticism of her colleagues, and adhered even more emphatically to her own strategy

Suivi prospectif à une année des prothèses de genou F.I.R.S.T. Evolution avec analyse ambulatoire de la marche

Le but de mon travail de master est de présenter les résultats à une année postopératoire d'une étude prospective sur une nouvelle prothèse totale du genou : la F.I.R.S.T. Evolution. Cette prothèse s'intéresse à des patients plus jeunes, avec une importante laxité des ligaments collatéraux. L'étude finale suivra à cinq ans une cohorte de cinquante patients environ. Actuellement, nous suivons 17 patients opérés avec cette prothèse (dont 9 femmes et 8 hommes, 9 genoux droits et 8 genoux gauches) avec un âge moyen de 69,10 ans (de 42 à 83 ans). Pour l'obtention des résultats, les patients ont remplis des questionnaires spécifiques couramment utilisés (Eq5D, WOMAC, KSS, échelle analogique de la douleur EVA/VAS, UCLA activity-rating level), ont bénéficié de contrôles radiologiques réguliers et d'une analyse régulière de la marche, à trois vitesses différentes. Cette analyse est objective et se base sur un système de capteurs miniaturisés. Les résultats cliniques obtenus à une année démontrent une amélioration globale de la fonction du genou et de la qualité de vie perçue par le patient (Eq5D, WOMAC, EVA/VAS, KSS, UCLA). Les données à une année de l'analyse de marche montrent une amélioration significative dans tous les paramètres du cycle de marche et aux différentes vitesses. En comparant nos résultats avec ceux précédemment obtenus, nous pouvons être satisfaits car ils se sont améliorés depuis la dernière échéance à 6 mois. De plus, nos résultats à une année suivent ceux obtenus dans d'autres études utilisant les mêmes questionnaires et une analyse objective de la marche. On s'attend à ce que ces données se stabilisent voire continuent de s'améliorer dans les années à venir.
