Previous work having shown that Bacillus-subtilis-S499-based biocontrol treatments applied without aeration at the steeping stage of red sorghum malting offered good mould reduction but yielded malts with low levels of key hydrolytic enzymes, we attempted to raise these levels by aerating the steeping liquor, varying the steeping time (from 8 to 40 h) and temperature (from 25 to 35°C), and combining a biocontrol treatment with prior steeping in 0.2% NaOH. Aeration proved particularly important whenever B. subtilis cells were present in the steep liquor. The optimal temperatures for α- and β-amylase were 30 and 25°C, respectively. By increasing the steeping time it was possible to improve the α-amylase activity, but the -amylase activity peaked sharply between 16 and 20 h, depending on the steeping medium. A good compromise was steeping in biocontrol medium for 14 to 16 h at 30°C. Combination steeping treatments (0.2% NaOH for 8 h followed by biocontrol for 8 h) yielded malts of a quality approaching that afforded by dilute alkaline treatment. [less ▲]

The objective of this prospective study was to investigate the success rate, practicality and complications of a new perilimbal pocket technique for the replacement of prolapsed nictitans gland in 30 dogs (44 eyes). A first incision was made in the bulbar conjunctiva, 2-3 mm from and parallel to the infero-nasal limbus, a second incision on the bulbar aspect of the nictitating membrane (NM), 2-3 mm parallel to the free edge. The gland was returned to its normal position by suturing the subconjunctival tissues of the NM to the episcleral tissues, using four to six interrupted horizontal mattress sutures. The English bulldog, Neapolitan mastiff, great dane and American cocker spaniel were commonly presented. Nictitans gland prolapse occurred prior to one year of age in 83.3 per cent of dogs, and unilaterally in 15 patients. The procedure was easy to perform, and had a 90.9 per cent success rate, with minimal complications. The median duration of follow-up, conducted by ophthalmic examination or telephone contact with the owners, was 21.5 months. Tear production and ocular health were not affected in 17 eyes with at least six months follow-up. There was a statistically significant increase between preoperative and postoperative Schirmer tear test-1 measurements. [less ▲]

Introduction à la biographie de Joseph Lebeau

Le 19 avril 1839, l’acceptation par les Pays-Bas du traité des 24 articles marque une nouvelle étape dans l’Histoire de Belgique. La Belgique ne vit plus sous la menace d’un retour de l’armée hollandaise. Malgré cet apaisement avec son voisin du nord, le pays n’en est pas moins rapidement confronté à de nouvelles difficultés : d’une part les premières tensions entre libéraux et catholiques apparaissent et commencent à déstabiliser le Gouvernement ; d’autre part la crise d’Orient menace de dégénérer en guerre européenne. C’est dans ce contexte houleux que Joseph Lebeau est rappelé à la tête de l’exécutif par le Roi (18 avril 1840 – 13 avril 1841). Il s’y illustre à nouveau comme chef de cabinet et ministre des Affaires étrangères. Cet épisode de la carrière de Lebeau est généralement moins connu du grand public. Pourtant, son action à cette époque est parfaitement révélatrice de la définition que l’homme d’Etat possède de la direction politique belge et de ce qu’elle doit être tant sur le plan national qu’international. Une fois le contexte historique planté, la conférence donnée le 8 septembre dans le cadre des journées du patrimoine se concentre sur le tournant des années 1840 en Belgique, parce qu’il constitue une étape importante pour la compréhension de la personnalité de Joseph Lebeau et plus largement pour l’histoire de notre pays.

Altération hydrothermale du béryl et formation de ses minéraux secondaires dans la pegmatite de Prà della Munega (Sondrio, Italie)

Beryl crystals have been found in the pegmatite of Prà della Munega rich in feldspars, quartz, muscovite and garnet. This pegmatite outcrops near Chiavenna, in Sondrio Province, Lombardy, Italy. These beryls show different degrees of alteration according to their localization in the pegmatite. Electron microprobe analyzes and X-ray diffraction mesurments (powder and four circles diffractometer) allowed to identify several silicates produced by the alteration of beryl: bavenite, bertrandite, chiavennite, milarite. Chemical analyzes of these minerals show substitution mechanisms which affect beryl and bavenite. Crystal structures of bavenite, chiavennite and milarite were also resolved. These structures are in accordance to structures described in literature, except milarite which Na’s site occupies a slightly shifted position compared with mirror plan. Petrographic observations and the Rietveld methodology allowed to define asequence of alteration. During the alteration, the shape of original beryl is conserved. Bavenite crystallizes in the shape of original beryl, bertrandite and chiavennite crystallize in the shape of original beryl and out of this, and milarite crystallizes out of the shape of original beryl due to a mobilization of Be by pegmatitic fluids. Bavenite and bertrandite are the first minerals to crystallize with an input of Ca, Mn, K, Si, Li, Be and Rb which results of the metasomatism of Na (albitization). These fluids, with a temperature of 350°C, destabilize the beryl and allow the crystallization of these alteration-induced minerals. Chiavennite and milarite are the last minerals who crystallize in the system with an input of K and Mn. These fluids, reaching low temperature and rich in K and Mn, could originate from late metamorphic fluids or residual fluids in pegmatites. [less ▲]

Génitif -aes/-es pour -ae : hellénisme ou vulgarisme ?

The origin of the genitive –aes/-es for –ae is difficult to establish. The most common opinion about this type of genitive, which occurs in epigraphical and, in more reduced proportions, in papyrological sources (not, insofar as I know, in literary texts) especially for women’s personal names (but also in common nouns), is that it comes from the Greek. Beside the influence of Greek, several theories can be found about the origin of this particularity, commonly attested even in Republican Latin names. Indeed, in vulgar Latin, the –es ending genitive (used as dative as well) was frequently used from the 1st c. B.C. This phenomenon can be observed in Rome, in Italy and in the provinces (not only in western provinces, but also in eastern provinces, where the influence of Greek could have been stronger). In the epigraphical texts, this type of genitive occurs frequently in Greek personal names among some social groups (low classes). The origin of the dedicants (native, Greek or Oriental, i.e. Greek-speaking persons) must be taken into account and, for the common nouns, the contextualization is very important. I’ll focus on the inscriptions from Asia Minor and compare them with other regions as Italia X and Pannonia to see : 1° whether –aes/-es are two distinctive phenomena or two variants of the same phenomenon and 2° if this particularity has been used as a typical feature to point out the Greek origin of the person(s) mentioned in the inscription or the bilingual character of the community which has produced the text.
