Fetus acardius amorphous: a rare case report
No full textFetus acardius amorphous is a rare fetal malformation, lacking a functional heart and bearing no resemblance to human embryos. The main differential diagnosis is with placental teratoma and is based on the degree of skeletal organization and umbilical cord formation. A 27-year old woman delivered a healthy newborn at 36 weeks gestation. An oval well defined mass, covered with normal looking skin, was connected to the placenta with a thin walled vessel. X-ray examination of the mass revealed the presence of vertebral column. Histopathologic examination demonstrated the presence admixture of tissues including neural tissue, osteoid, cartilage, muscle, fat etc. beneath the skin. The rarity of fetal monsters without a functioning heart is emphasized.</jats:p
Contribution to the knowledge of the genus Alchemilla L. (Rosaceae) in Tuscany, Italy
No full textAfter extensive fieldwork and the study of herbarium specimens with reliable identifications, 35 Alchemilla species are documented as currently occurring in Tuscany. For A. glomerulans Buser and A. demissa Buser only historical data are available. Alchemilla polytricha Buser is a taxonomically doubtful species, very likely to be included within the variability of A. glaucescens Wallr. as well as A. hybrida (L.) L. The historical Tuscan samples of A. cinerea Buser should be referred to A. acutata Buser. The following twelve species are to be excluded from the regional flora: A. compta Buser, A. coriacea Buser, A. exigua Buser ex Paulin, A. fissa Günther & Schummel, A. flavovirens Buser, A. impexa Buser, A. leptoclada Buser, A. radiisecta Buser, A. sinuata Buser, A. subsericea Reut., A. trunciloba Buser, and A. vulgaris L. s.str. The most common species, and one of the few occurring also at altitudes lower than 1,000 m a.s.l., is A. glaucescens Wallr., followed by A. xanthochlora Rothm. Within species of the “A. alpina” group, the most frequent species are Alchemilla lucida Buser, A. saxatilis Buser, and A. alpina L. s.str. On the contrary, there are very rare species, often limited to one or few localities: A. crinita Buser (Pistoia Apennine, Val di Luce), A. cymatophylla Juz. (Pistoia Apennine at Sestaione), A. hoppeana (Rchb.) Dalla Torre (Pistoia Apennine above Butale), A. opaca Buser (Pistoia Apennine at Verginetta), A. straminea Buser (Pistoia Apennine towards Tre Potenze), A. strigosula Buser (Mt. Falterona), and A. subcrenata Buser (Apuan Alps near Carcaraia). Finally, the Tuscan endemic A. ceroniana was re-collected in the locus classicus, more than 100 years after its description. This finding allowed to detail a morphological description and to compare this species with closely related taxa

The SASSCAL contribution to climate observation, climate data management and data rescue in Southern Africa
No full textA major task of the newly established "Southern African Science Service Centre for Climate Change and Adaptive Land Management" (SASSCAL; www.sasscal.org) and its partners is to provide science-based environmental information and knowledge which includes the provision of consistent and reliable climate data for Southern Africa. Hence, SASSCAL, in close cooperation with the national weather authorities of Angola, Botswana, Germany and Zambia as well as partner institutions in Namibia and South Africa, supports the extension of the regional meteorological observation network and the improvement of the climate archives at national level. With the ongoing rehabilitation of existing weather stations and the new installation of fully automated weather stations (AWS), altogether 105 AWS currently provide a set of climate variables at 15, 30 and 60 min intervals respectively. These records are made available through the SASSCAL WeatherNet, an online platform providing near-real time data as well as various statistics and graphics, all in open access. This effort is complemented by the harmonization and improvement of climate data management concepts at the national weather authorities, capacity building activities and an extension of the data bases with historical climate data which are still available from different sources. These activities are performed through cooperation between regional and German institutions and will provide important information for climate service related activities
El discurso de género del Plan de Seguridad Alimentaria, Nutrición y Erradicación del Hambre de la Comunidad de Estados Latinoamericanos y Caribeños (CELAC)
No full textWith the objective of discussing the SAN CELAC Plan and its gender strategy, the article analyzes its discourse in the light of feminist theory. Supported by a methodological framework of analysis of social and political discourse, the work reviews the Plan for Food Security, Nutrition and Eradication of Hunger of CELAC 2025 and the Gender Strategy of the SAN-CELAC Plan, to account for the lack of a feminist theorization or approach in its gender perspective.Con el objetivo de discutir del Plan SAN CELAC y su estrategia de género, el artículo, analiza su discurso a la luz de la teoría feminista. Apoyado en un marco metodológico de análisis del discurso social y político, el trabajo revisa el Plan Para la Seguridad Alimentaria, Nutrición y Erradicación del Hambre de la CELAC 2025 y la Estrategia de Género del Plan SAN-CELAC, para dar cuenta de la falta de una teorización o enfoque feminista en su perspectiva de género
