Silene astartes C.I. Blanche ex Boiss., Fl. Orient. Suppl.
No full textSilene astartes C.I. Blanche ex Boiss., Fl. Orient. Suppl.: 102. 1888. Lectotypus (designated here): Lebanon . Prov. Mount-Lebanon: Djebaïl, ruines d’AFka, VI-VII.1880, fl. & Fr., Blanche 55 (G-BOIS [G00330604]!; isolecto-: BEI!, G [G00341654]!) (Fig. 1). Notes. – Boissier (1888) published S. astartes in the “Supplementum oF the Flora Orientalis”. He wrote “ S. astartes (Blanche in litt.)” beFore the Latin description. Ŋe mention oF Blanche as the author “in litt.” by Boissier has been interpreted in different ways in the literature. Floras oF Lebanon have cited only C.I. Blanche as the author oF the species (sometimes with the mention “in Boiss.”; Post, 1896, 1932; ThiÉbaut, 1936; Mouterde, 1966; TohmÉ & TohmÉ, 2007), whereas BouloumoY (1930) interpreted the authorship as “Boiss. et B.” [Boiss. & C.I. Blanche]. In the Boissier’s Herbarium oF the “Flora Orientalis” (G-BOIS), Blanche 55 contains a handwritten note by Blanche himselF with a Latin description oF the species (Fig. 1). However this description differs considerably From the protologue where Boissier published a new and more complete description by validating the name (Boissier, 1888: 102). We thereFore ascribe Boissier as the author oF S. astartes in accordance with Greuter et al. (1984) and not as C.I. Blanche as mentioned in the latest flora oF Lebanon treatment (TohmÉ & TohmÉ, 2007). Boissier (1888) clearly cited two gatherings in the protologue: “Hab. in Libano supra Djebail ad minas AFka (Bl.!)” and “ad Ain SuFar (Peyron!)”. Only Blanche 55 [G00330604] is present in G-BOIS. We Found three duplicates oF the Peyron collection at G and one at P. Each oF them bears the locality “Ain SuFar” and are dated June 11, 1882. Two oF them have the collection number 1379 mentioned [G00341656, P04987226]) and two [G00341655, G00341657] without any number. All these collections have a glandular-pubescent calyx and match Fully with S. italica (L.) Pers. and not with S. astartes, which has a calyx always glabrous. ŊereFore, we choose Blanche 55 housed at G-BOIS as the lectotype, which is the only material present at G-BOIS and exclude the remaining syntypes From S. astartes.Published as part of Pierre-Emmanuel Du Pasquier & Daniel Jeanmonod, 2016, Lectotypification of three species of Silene sect.

Establishing the test–retest reliability & concurrent validity for the repeat ice skating test (RIST) in adolescent male ice hockey players
No full textIn this study the authors examine the test–retest reliability and concurrent validity of the Repeat Ice Skating Test (RIST). This was an on-ice field anaerobic test that measured average peak power and was validated with 3 anaerobic lab tests: (a) vertical jump, (b) the Margaria–Kalamen stair test, and (c) the Wingate Anaerobic Test. The participants (n = 14) were 11- to 12-year-old males selected from a Peewee “A” level ice hockey team (Thunder Bay, Canada). The results of the test–retest reliability estimation showed that the RIST was a reliable test at measuring average peak power in watts (R = .99, C.I.95% = 0.97 to 0.99) and watts per kilogram (R = .98, C.I.95% = 0.94 to 0.99). The RIST was also a valid test when correlated with the 3 anaerobic lab tests for measuring peak power in watts: vertical jump (r = .86, C.I.95% = 0.72 to 0.94), Margaria–Kalamen stair test (r = .66, C.I.95% = 0.39 to 0.83) and Wingate Anaerobic Test (r = .86, C.I.95% = 0.72 to 0.93). The test is considered promising because it does not require any specific equipment, and is a sport-specific, on-ice test, that can be administered during a regular ice hockey practice session
C.I. Acid Black 1 transfer from dilute solution to perlite framework in organic waste management
No full textDyes, considered as toxic and persistent pollutants, must be removed from organic wastes prior to their composting and application in sustainable agriculture. Azo dyes, capable of altering the physicochemical properties of soil, are difficult to expel by conventional wastewater treatments. C.I. Acid Black 1 (AB 1), a sulfonated azo dye, inhibits nitrification and ammonification in the soil, lessens the nitrogen use efficacy in crop production and passes substantially unaltered through an activated sludge process. The retention of C.I. Acid Black 1 by raw and expanded perlite was investigated in order to examine the potential effectiveness of this aluminosilicate material toward organic waste cleanup. Dye adsorption proved spontaneous and endothermic in nature, increasing with temperature for both perlites. Expanded perlite having a more open structure exhibited a better performance compared to the raw material. Several of the most widely recognized two-parameter theoretical models, i.e., Langmuir, Freundlich, Temkin, Brunauer–Emmett–Teller (BET), Harkins–Jura, Halsey, Henderson, and Smith, were applied to reveal physicochemical features characterizing the adsorption. The Langmuir, Freundlich, Temkin, BET, Henderson, and Smith equations best fitted experimental data indicating that the adsorption of anionic dye on perlites is controlled by their surface, i.e., non-uniformity in structure and charge. This heterogeneity of surface is considered responsible for promoting specific dye adsorption areas creating dye “islands” with local dye supersaturations. © The Author(s) 2024

Shared aperture array antennas composed of differently sized
No full textA novel solution for conceiving wide band (multi-band) array antennas is presented. The solution is based on the concept of interleaving sparse, sub-arrays operating at separate frequencies. Sparse array antennas offer two major advantages, namely: they have non-uniformly distributed elements, with possibly large distances between elements (this providing the necessary space for interleaving different sub-arrays), and they do not require the amplitude tapering of the elements for controlling the array radiation pattern.Electrical Engineering, Mathematics and Computer Scienc
Neighborhood-level socioeconomic and urban land use risk factors of canine leptospirosis: 94 cases (2002–2009)
Full text linkAssociations of housing, population, and agriculture census variables, and presence near public places were retrospectively evaluated as potential risk factors for canine leptospirosis using Geographic Information Systems (GIS). The sample population included 94 dogs positive for leptospirosis based on a positive polymerase chain reaction test for leptospires on urine, isolation of leptospires on urine culture, a single reciprocal serum titer of 12,800 or greater, or a four-fold rise in reciprocal serum titers over a 2–4 week period; and 185 dogs negative for leptospirosis based on a negative polymerase chain reaction test and reciprocal serum titers less than 400. Multivariable logistic regressions revealed different risk factors among different census units; however, houses lacking complete plumbing facilities [OR = 2.80, 95% C.I. = 1.82, 4.32 (census unit, block group); OR = 1.36, 95% C.I. = 1.28, 1.45 (census tract); OR = 3.02, 95% C.I. = 2.60, 3.52 (county)]; and poverty status by age (18–64) [OR = 2.04, 95% C.I. = 1.74, 2.39 (block group); OR = 1.53, 95% C.I. = 1.41, 1.67 (census tract); and OR = 1.62, 95% C.I. = 1.50, 1.76 (county)] were consistent risk factors for all census units. Living within 2500 m of a university/college and parks/forests were also significantly associated with leptospirosis status in dogs. Dogs that live under these circumstances are at higher risk for leptospirosis and pet owners should consider vaccination
