Estudos sobre a nutrição mineral do cafeeiro: XL. Fitomassa e conteúdo de macro e micronutrientes no material podado

Foi conduzido um ensaio numa plantação comercial de café de variedade Mundo Novo de 9 anos de idade, com uma população de 1904 covas/ha, destinada a avaliar a quantidade de biomassa e de nutrientes removidas por diferentes tipos de poda: recepa a 0,40m; decote a 1,00, 1,50 e 2,00 m; decote a 1,50m com esqueletamento. A análise do material e dos dados permitiu tirar-se as seguintes conclusões: (1) a biomassa removida pela poda foi maior na recepa (24,3 t de matéria fresca e 11,9 de matéria seca) e no decote a 1,00 m (20,6 e 10,1 t, respectivamente); seguia-se o decote a 1,50 m com esqueletamento que deu 19,4 e 8,3 t de matéria fresca e seca por hectare; os pesos da matéria fresca e seca correspondentes aos decotes a 1,50 m e 2,00 m foram: 12,1 e 5,4; 5,6 e 2,5 t/ha; (2) a relação existente entre a altura de poda e quantidade de fitomassa removida é descrita por equações de regressão simples; (3) as quantidades de nutrientes removidas são proporcionais as quantidades de material podado sendo as seguintes de acordo com a ordem dos tratamentos dado, em kg/ha: N - 320, 294, 162, 80 e 261; P - 18, 15, 10, 44 e 16; K - 286, 266, 168, 78 e 273; Ca - 149, 139, 63, 33 e 101: Mg - 30, 33, 16, 8 e 26; S - 10, 7,6, 3 e 10; as quantidades de micronutrientes removidas foram, em g/ha: B - 306, 337, 163, 83 e 268; Cu - 229, 219, 121, 51 e 191; Fe - 2783, 2328, 1367, 544 e 2,088; Mn - 437, 779, 264, 142 e 412; Zn - 174, 152, 74, 28 e 121; (3) foram derivadas equações de regressão simples que relacionam quantidade extraídas e altura da poda; (4) a reciclagem de fitomassa contribui com economia substancial de fertilizantes para a nova vegetação. Cerca de dois terços e três quartos de nutrientes, entretanto, estão contidos no material lenhoso de caules e ramos o que deve fazer que a sua disponibilidade seja mais lenta.

Scoring rules on dichotomous preferences

In this paper, we study individual incentives to report preferences truthfully for the special case when individuals have dichotomous preferences on the set of alternatives and preferences are aggregated in form of scoring rules. In particular, we show that (a) the Borda Count coincides with Approval Voting on the dichotomous preference domain, (b) the Borda Count is the only strategy-proof scoring rule on the dichotomous preference domain, and (c) if at least three individuals participate in the election, then the dichotomous preference domain is the unique maximal rich domain under which the Borda Count is strategy-proof.

On Boas-Type Problem

R.P. Boas has found necessary and sufficient conditions of belonging of function to Lipschitz class. From his findings it turned out, that the conditions on sine and cosine coefficients for belonging of function to Lip α(0 & α & 1) are the same, but for Lip 1 are different. Later his results were generalized by many authors in the viewpoint of generalization of condition on the majorant of modulus of continuity. The aim of this paper is to obtain Boas-type theorems for generalized Lipschitz classes. To define generalized Lipschitz classes we use the concept of modulus of smoothness of fractional order.

La práctica médico-quirúrgica en la primera generación del movimiento "novator" a través de las obras de Juan Bautista Juanini (Milán, 1632 - Madrid, 1691): imagen historiográfica, saberes médicos y prácticas quirúrgicas

El objetivo principal de este trabajo es realizar un nuevo acercamiento a la figura histórica, la obra y, en concreto, la práctica médico-quirúrgica de un autor hispanoitaliano de finales del siglo XVII. Nos referimos concretamente al cirujano cortesano Juan Bautista Juanini (Milán, 1632 – Madrid, 1691). Como objetivo secundario se trataría de intentar realizar una nueva presentación biográfica del autor dentro de una recapitulación más general del papel que representó en el contexto de la revolución científica y médica de los países del sur de Europa, y en concreto entre los miembros de la primera generación de "novatores" hispánicos.

Safe dissection of the distally based anterolateral thigh flap.

Background The distally based anterolateral thigh (ALT) flap is an interesting reconstructive solution for complex soft tissue defects of the knee. In spite of a low donor site morbidity and wide covering surface as well as arch of rotation, it has never gained popularity among reconstructive surgeons. Venous congestion and difficult flap dissection in the presence of a variable anatomy of the vascular pedicle are the possible reasons.Methods An anatomical study of 15 cadaver legs was performed to further clarify the blood supply of the distally based ALT. Our early experience with the use of preoperative angiography and a safe flap design modification that avoids distal intramuscular skeletonization of the vascular pedicle and includes a subcutaneous strip ranging from the distal end of the flap to the pivot point is presented.Results The distally based ALT presents a constant and reliable retrograde vascular contribution from the superior genicular artery. Preoperative angiography reliably identified and avoided critical Shieh Type II pedicled flaps. The preservation of a subcutaneous strip ranging from the distal flap end to the upper knee was associated with the absence of venous congestion in a short case series.Conclusions Preoperative angiography and a flap design modification are proposed to allow the safe transfer of the distally based ALT to reconstruct soft tissue defects of the knee.

Application extraterritoriale du droit international des droits de l'homme

Les obligations de l'Etat en matière de droits de l'homme s'étendent-elles au-delà de ses frontières? Le sujet prend une importance considérable actuellement: interventions militaires à l'étranger, opérations de paix, occupation militaire, centres de détention à l'étranger, mouvements séparatistes soutenus par un Etat étranger, éloignement des étrangers, entraide judiciaire et administrative internationale, exequatur de décisions étrangères violant les droits de l'homme... Ces thèmes, et d'autres, sont abordés dans l'ouvrage sous l'angle du Pacte ONU II, de la CEDH, et de la Convention et la Déclaration américaines dans une approche comparative et systématique. L'ouvrage analyse en détail la jurisprudence et la pratique internationales relatives à ces instruments. L'auteur est avocat au Barreau du Canton de Vaud (Lausanne) et titulaire d'un LL.M. de l'Université de Cambridge.

Els teus ulls t'enganyen?

Treball de recerca realitzat per alumnes d’ensenyament secundari i guardonat amb un Premi CIRIT per fomentar l'esperit científic del Jovent l’any 2008. Per què cada persona interpreta d’una manera diferent una il•lusió òptica? Quins són els factors que afecten a aquesta interpretació diferent de la realitat? S’analitzen els conceptes de percepció i il•lusió òptica mitjançant una recerca bibliogràfica. Posteriorment s’ha investigat per esbrinar els possibles factors que distorsionen la percepció. Algunes limitacions, com ara el temps i els recursos necessaris només han permés centrar-se en quatre factors: la miopia, l’astigmatisme, l’edat i el sexe. La recerca que s’ha dut a terme consisteix en la realització d’unes enquestes i la posterior extracció de les conclusions a partir d’aquestes mitjançant un programa estadístic. Es conclou que els defectes visuals i l’edat són factors importants que alteren la percepció visual; els factors socioculturals afecten en part la mateixa percepció, i el sexe no afecta la percepció visual.

Reasons why emergency department providers do not rely on the pneumonia severity index to determine the initial site of treatment for patients with pneumonia.

BACKGROUND: Many emergency department (ED) providers do not follow guideline recommendations for the use of the pneumonia severity index (PSI) to determine the initial site of treatment for patients with community-acquired pneumonia (CAP). We identified the reasons why ED providers hospitalize low-risk patients or manage higher-risk patients as outpatients. METHODS: As a part of a trial to implement a PSI-based guideline for the initial site of treatment of patients with CAP, we analyzed data for patients managed at 12 EDs allocated to a high-intensity guideline implementation strategy study arm. The guideline recommended outpatient care for low-risk patients (nonhypoxemic patients with a PSI risk classification of I, II, or III) and hospitalization for higher-risk patients (hypoxemic patients or patients with a PSI risk classification of IV or V). We asked providers who made guideline-discordant decisions on site of treatment to detail the reasons for nonadherence to guideline recommendations. RESULTS: There were 1,306 patients with CAP (689 low-risk patients and 617 higher-risk patients). Among these patients, physicians admitted 258 (37.4%) of 689 low-risk patients and treated 20 (3.2%) of 617 higher-risk patients as outpatients. The most commonly reported reasons for admitting low-risk patients were the presence of a comorbid illness (178 [71.5%] of 249 patients); a laboratory value, vital sign, or symptom that precluded ED discharge (73 patients [29.3%]); or a recommendation from a primary care or a consulting physician (48 patients [19.3%]). Higher-risk patients were most often treated as outpatients because of a recommendation by a primary care or consulting physician (6 [40.0%] of 15 patients). CONCLUSION: ED providers hospitalize many low-risk patients with CAP, most frequently for a comorbid illness. Although higher-risk patients are infrequently treated as outpatients, this decision is often based on the request of an involved physician.

An Analysis of the Electoral Use of Policy on Law and Order by New Labour

There has been much debate regarding the electoral strategy adopted by New Labour in the lead-up to and then during their time in government. This paper addresses the issue from the perspective of left/right and libertarian/authoritarian considerations by examining data on individual attitudes from the British Social Attitudes survey between 1986 and 2009. The analysis indicates that New Labour’s move towards the right on economic and public policy was the main driver towards attracting new centrist voters and could thus be labelled ‘broadly’ populist. The move towards a tougher stance on law and order was more ‘narrowly’ populist in that it was used more to minimise the reduction in support from Labour’s traditional base on the left than to attract new votes.
