No full textMicrolicia piatensis Almeda & R.B.Pacifico, sp. nov. (Figs. 18–19). Type:— BRAZIL. Bahia: Piatã, caminho para os Três Morros, estrada para Inúbia, 13°04’36.8”S, 41°54’21.1”W, 1376 m, 19 June 2022, fl., fr., R . Pacifico 659 & V.E. Bressan (holotype: HUEM!, isotypes: ALCB!, CAS!, HUEFS!, RB!). Diagnosis:—Differs from Microlicia sulfurea Hoehne (1922: 22) by the elliptic leaf blades (vs. ovate to lanceolate), anthers oblong (vs. oblong-linear), shorter antesepalous pedoconnectives 1.4–1.9 mm long (vs. 3.8–4.2 mm long), antesepalous appendages 0.5–0.8 mm long that are bilobate at the apex (vs. 1–1.2 mm long, apex truncate), and shorter antepetalous pedoconnectives 0.6–0.9 mm long (vs. 1.5–2 mm long). Erect shrubs 0.5–1.5 m tall, much-branched. Upper cauline internodes 1.5–3 mm long, light green (when fresh) becoming pale green (when dry) and defoliated with age, quadrangular, not sulcate, unwinged, densely glandularpunctate. Leaves decussate, ascending, not concealing uppermost internodes (both when fresh and when dry), chartaceous, concolored, light green (when fresh) becoming pale green (when dry); petioles 0.4–0.7 mm long, light green, flattened; blades 2.5–3 × 1–1.5 mm, elliptic, apex rounded, base cuneate, margins entire and glandular-punctate, flat, both surfaces densely glandular-punctate, 1-nerved, venation impressed on both surfaces, secondary venation not evident. Flowers 5(–6)-merous, on short pedicels 0.2–0.4 mm long (these lengthening to 1 mm long in fruit), apical, solitary, ebracteolate. Hypanthia (at anthesis) 2.8–3.1 mm long, 2.2–2.5 mm wide at the torus, light green (when fresh) becoming pale brown in fruit (and when dry), campanulate, equaling the capsule in length at maturity, densely glandular-punctate. Calyx tubes ca. 0.2–0.3 mm long. Calyx lobes 1–1.5 mm long, 1.3–1.7 mm wide at the base, light green (when fresh) becoming pale brown (when dry), nearly erect at anthesis, triangular, apex acute and mucronate, margins entire and glandular-punctate, externally glandular-punctate. Petals 4–5 × 3–4 mm, obovate, yellow, base attenuate, apex truncate, both surfaces glabrous, margins entire and glabrous. Stamens 10(12), entirely yellow, dimorphic, antesepalous anthers ± horizontal (at anthesis), subparallel and clustered, antepetalous anthers ± erect and clustered near the floral axis; antesepalous (larger) stamens with filaments 2–2.5 mm long, glabrous, thecae (excluding rostra) 1.6–1.9 × 0.4–0.5 mm, oblong, corrugate (polysporangiate), rostra 0.2–0.3 mm long, the ventrally inclined pores ca. 0.1 mm wide, nearly circular, pedoconnectives 1.4–1.9 mm long, appendages 0.5–0.8 mm long, apex bilobate; antepetalous (smaller) stamens with filaments 1.5–1.9 mm long, glabrous, thecae (excluding rostra) 1.5–2 × 0.3–0.5 mm, corrugate (polysporangiate), oblong, rostra 0.2–0.3 mm long, the ventrally inclined pores 0.1–0.2 mm wide, nearly circular, pedoconnectives 0.6–0.9 mm long, appendages 0.2–0.3 mm long, apex emarginate. Ovary (at anthesis) ca. 1 × 0.8 mm, superior, subglobose, glabrous, 3-locular, not adnate to the hypanthium; style 4–5 mm long, yellow, glabrous, sigmoid, stigma punctiform. Fruit at maturity a globose loculicidal capsule 1.5–2 × 1.3–1.7 mm, pale brown, ovoid, 3-valvate, enveloping hypanthia and rupturing and flaking away with age, dehiscent from the apex to the base (basipetal), columellas deciduous. Seeds ca. 0.3–0.4 × 0.2 mm, yellow, oblong, testa foveolate, raphal zone nearly circular, ca. 30% the length of the seed. Additional specimens examined: BRAZIL. Bahia: Piatã.

Distribution, habitat and phenology:— Probably restricted to the mountains of Piatã, Bahia, Brazil (Fig. 12, Appendix 2). It grows in campo rupestre (Fig. 4) exposed to full sun at elevations between 1350–1400 m. Microlicia piatensis was collected flowering and fruiting in June, August, September and December. Etymology:— The specific epithet refers to its distribution which is apparently restricted to Piatã, Bahia, Brazil (Fig. 12). Notes:— Besides M. sulfurea (Fig. 5G) and M. prostrata (see diagnoses of M. piatensis and M. prostrata, respectively), Microlicia piatensis is also possibly related to M. parvula (Markgraf 1927:44)Koschnitzke &A.B.Martins (2007: 474) (Fig. 5F). Both M. piatensis and M. parvula have an erect habit, a glandular-punctate indumentum on branches, leaves and hypanthia, somewhat elliptic leaves, triangular calyx lobes, yellow petals, and yellow stamens with polysporangiate thecae. Microlicia piatensis can be differentiated by its leaves with conspicuous petioles 0.4– 0.7 mm long (vs. petioles absent or inconspicuous, up to 0.2 mm long), and dimorphic stamens with conspicuous pedoconnective appendages (vs. isomorphic to subisomorphic, inconspicuous appendages). Among the compared species, only M. parvula apparently grows sympatrically with M. piatensis in Piatã, Bahia (see Appendix 1). Suggested conservation status:— Critically Endangered (CR): B1ac(iii)+B2ac(iii) (see Appendix 2).Published as part of Pacifico, Ricardo & Almeda, Frank, 2022, New species of Marcetia and Microlicia (Melastomataceae) endemic to the campo rupestre of Chapada Diamantina, Bahia, Brazil, pp. 39-69 in Phytotaxa 573 (1) on pages 58-60, DOI: 10.11646/phytotaxa.573.1.3, http://zenodo.org/record/732945

No full textA TCT and annealing study on Magnetic Czochralski silicon detectors irradiated with neutrons and 24-GeV/c protons
No full textSilicon diodes (pad detectors) were irradiated with 24GeV/c protons at the CERN PS IRRAD1 facility and with neutrons at the TRIGA reactor in Ljubljana (Slovenia). The diodes were realized on Magnetic Czochralski (MCz) grown silicon, of both n- and p-type. After irradiation, an annealing study with CV measurements was performed on 24GeV/c proton irradiated detectors, looking for hints of type inversion after irradiation and during annealing. Other pad detectors were studied using the TCT (transient current technique), to gather information about the field profile in the detector bulk and thus about the effective space charge distribution within it
Ureaplasma urealyticum as a cause of pneumonia in preterm infants - analysis of the white cell response
No full textThe tracheal isolation of Ureaplasma urealyticum from critically ill infants was investigated to determine if the organism was associated with an inflammatory response. Twenty nine neonates consecutively admitted for acute respiratory disease, with birthweights of < 1301 g and no evidence of viral, chlamydial, or bacterial infections, were identified. Culture results for ureaplasmas were correlated with white cell counts and clinical and radiographic features. Sixteen infants had tracheal aspirates and/or blood specimens positive for U urealyticum. Pneumonia was diagnosed more frequently in the U urealyticum positive infants than in the 13 who were negative for the organism. The mean total white cell count, absolute neutrophil, and band form counts were significantly higher in the U urealyticum positive group than in the negative group. These data suggest that U urealyticum can induce an inflammatory response in selected individuals who present with clinical, radiographic, and, in some instances, histological features of pneumonia
