Le manuscrit de Paris, BNF, fr. 818, connu des francoprovençalistes pour sa collection de légendes hagiographiques en scripta lyonnaise, renferme également l'une des plus amples collections de miracles de Notre-Dame en langue vernaculaire du XIIIe siècle. À la différence des Légendes en prose, ce « Mariale » en vers (probablement dû au même auteur anonyme) a été rédigé dans une scripta 'francoprovençalisante', soit dans une langue qui se veut française, mais qui laisse transparaître un bon nombre de traits de l'idiome natal de l'auteur. Longtemps demeuré dans l'ombre des Légendes, le Mariale lyonnais restait jusqu'ici partiellement inédit, et sa langue n'avait jamais fait l'objet d'une étude exhaustive. Le présent ouvrage comble cette double lacune en proposant d'une part l'édition, la traduction et le glossaire des miracles qui restaient à faire connaître, d'autre part une étude linguistique portant sur l'ensemble du corpus et mettant en lumière la richesse des matériaux francoprovençaux offerts par ce recueil.

L'organisation des manuscrits arthuriens du cycle du Graal de Jacques d'Armagnac (BNF fr. 117-120 qu'il a hérité de son arrière-grand-père le duc Jean de Berry et dont il a fait retoucher les peintures et BNF fr. 113-116 qu'il a fait exécuter entre 1470 et 1475), leur agencement, leur illustration et leurs subdivisions sont un indice précieux de la conception et de la réception de ces compilations. Ils soulignent l'effort de constitution d'un ensemble romanesque cohérent centré sur la figure de Lancelot.

The ms. Paris, BnF, fr. 344 was produced in Lorraine at the end of the thirteenth century and contains the whole Lancelot-Grail cycle. It presents an abridged version of the end of the Vulgate Sequel to Merlin. The rewriting of the end of the sequel glosses over the romantic episodes of the common version and focuses on the figure of Arthur, a legitimate sovereign and skilful war leader confronted by his barons’ dissidence. From the end of f° 182 to f° 184v°, BnF, fr. 344, narrates the departure of Kings Ban and Bohort for the Continent, the embassy of King Loth and his sons, and the fight against the Saxons of the Christian coalition gathered at Logres for the feast of the Holy Cross. This article shows the ideological implications of the abridgement and the illustration used at the end of the Vulgate Sequel in ms. fr. 344, as it exalts Arthur’s kingship and insists on the rallying, penance and submission of his rebelled vassals.

Although since 1984 there are Rhizobium strains available for common bean inoculation in Brazil, a survey in 2014 showed that only 15% of the Brazilian farmers adopt inoculation as a routine practice. Part of this disbelief in relation to common beans inoculation can be attributed to the fact that supposedly, bean inoculation would not be able to support increased yield levels in high-tech farms, being appropriate only for small farms. A series of demonstration units carried out since 2012, under farm conditions in the Cerrado region, have showed that a 10.8% mean increase in yield were obtained only with inoculation in relation to the treatment without inoculation and without nitrogen fertilization (whose average yield was 3163 kg ha-1). It was also found that inoculation with supplementation of 60 kg ha-1 of N promoted yield levels (4010 kg ha-1) higher than those with 120 kg ha-1 N as urea (3411 kg ha-1).

Rat lung microsomes were shown to �-hydroxylate acyclic monoterpene alcohols in the presence of NADPH and O2. NADH could neither support hydroxylation efficiently nor did it show synergistic effect. The hydroxylase activity was greater in microsomes prepared from β-naphthoflavone (BNF)-treated rats than from phenobarbital (PB)-treated or control microsomal preparations. Hydroxylation was specific to the C-8 position in geraniol and has a pH optimum of 7.8. The inhibition of the hydroxylase activity by SKF-525A, CO, N-ethylmaleimide, ellipticine, α-naphthoflavone, cyt. Image and p-CMB indicated the involvement of the cyt. P-450 system. However, NaN3 stimulated the hydroxylase activity to a significant level. Rat kidney microsomes were also capable of �-hydroxylating geraniol although the activity was lower than that observed with lungs.

In agricultural systems which rely on organic sources of nitrogen (N), of which the primary source is biological N fixation (BNF), it is extremely important to use N as efficiently as possible with minimal losses to the environment. The amount of N through BNF should be maximised and the availability of the residual N after legumes should be synchronised to the subsequent plant needs in the crop rotation. Six field experiments in three locations in Finland were conducted in 1994-2006 to determine the productivity and amount of BNF in red clover-grass leys of different ages. The residual effects of the leys for subsequent cereals as well as the N leaching risk were studied by field measurements and by simulation using the CoupModel. N use efficiency (NUE) and N balances were also calculated. The yields of red clover-grass leys were highest in the two-year-old leys (6 700 kg ha-1) under study, but the differences between 2- and 3-year old leys were not high in most cases. BNF (90 kg ha-1 in harvested biomass) correlated strongly with red clover dry matter yield, as the proportion of red clover N derived from the atmosphere (> 85%) was high in our conditions of organically farmed field with low soil mineral N. A red clover content of over 40% in dry matter is targeted to avoid negative N-balances and to gain N for the subsequent crop. Surprisingly, the leys had no significant effect on the yields and N uptake of the two subsequent cereals (winter rye or spring wheat, followed by spring oats). On the other hand, yield and C:N of leys, as well as BNF-N and total-N incorporated into the soil influenced on subsequent cereal yields. NUE of cereals from incorporated ley crop residues was rather high, varying from 30% to 80% (mean 48%). The mineral N content of soil in the profile of 0-90 cm was low, mainly 15-30 kg ha-1. Simulation of N dynamics by CoupModel functioned satisfactorily and is considered a useful tool to estimate N flows in cropping systems relying on organic N sources. Understanding the long-term influence of cultivation history and soil properties on N dynamics remains to be a challenge to further research.
