No full textDentella repens (L.) J.R. Forst. & G. Forst., Char. Gen. Pl.: 25, tab: 13. 1775. Oldenlandia repens L., Mant. Pl. 1: 40. 1767. Lectotypus (designated by VERDCOURT, 1983b): INDIA [?]: sine loco, s.d., Anon. s.n. (LINN nº 155/2). Small prostrate herb, rooting at nodes. Stems and leaves fleshy, leaf blades subsessile, 4– 5 × 1.5– 2 mm, obovate to spathulate, base narrowed, apex acute; stipules connate. Flowers axillary, solitary, sessile, 5-merous. Calyx tube c. 1 mm long; lobes 5, subulate. Corolla tube funnel-shaped, greenyellowish, glabrous outside and inside; lobes white, toothed. Stamens 5, included, attached in the middle of corolla tube. Ovary 2-celled; style filiform; stigma 2-lobed. Fruits globose, indehiscent, densely villous with multicellular, transparent, bulbous-tipped trichomes, becoming glabrescent when fully mature, many-seeded with persistent calyx crown. Seeds minute, angular, brown, rugose. Specimen examined. – MADAGASCAR.Reg. Sofia [Prov. Mahajanga]: Dist. Analalava, Cne. Antonibe, Fkt.

Note. – We postulate that D. repens may well have reached Madagascar via a long-distance dispersal either from Sri Lanka or Mauritius. On the other hand, it is possible that the species might be present in East Africa and remains unnoticed. In this case, a long-distance dispersal from East Africa to Madagascar cannot be ruled out.Published as part of Razafimandimbison, Sylvain G. & Manjato, Nadiah, 2019, First record of Dentella repens (Rubiaceae) from Madagascar, pp. 43-45 in Candollea 74 (1) on page 44, DOI: 10.15553/c2019v741a6, http://zenodo.org/record/572465
Casuarina: Casuarina equisetifolia L. ex J.R. Forst. & G. Forst., árbol de uso múltiple en América Central
No full text12 figuras, 10 tablasEste documento presenta las experiencias y conocimientos que, hasta la fecha se tienen en América Central, sobre el cultivo de la casuarina (Casuarina equisetifolia L. ex. J.R. Forst / G. Forst.). Una especie de árbol de uso múltiple de gran importancia en la región. La casuarina es una de las especies que más se cultiva en las zonas bajas de la región para la Producción de leña, poste, tutores para hortalizas, madera para constrcción rural y para Producción de carbón. Las razones para este uso generalizado son: el crecimiento rápido facilidad de asocio con cultivos utilidad en la formación de cortinas rompevientos y cercos vivos y la calidad de la mader
Skrining Fitokimia Dan Uji Toksisitas Ekstrak Akar Parang Romang (Boehmeria virgata (Forst)Guill) terhadap Larva Udang Artemia salina L
No full textTelah dilakukan penelitian tentang skrining fitokimia dan uji toksisitas akar Parang Romang (Boehmeria virgata (Forst) Guill) terhadap larva udang Artemia salina L. Tujuan dari penelitian ini adalah mengetahui golongan senyawa yang terkandung dalam ekstrak etanol akar Boehmeria virgata (Forst) Guill dan mengetahui potensi toksisitas akut pada ekstrak akar Boehmeria virgata (Forst) Guill menurut metode Brine Shrimp Lethality Test (BST). Serbuk akar Boehmeria virgata (Forst) Guill diekstraksi dengan metode maserasi menggunakan pelarut etanol 96 %. Ekstrak cair yang diperoleh kemudian diuapkan untuk mendapatkan ekstrak kental. Skrining fitokimia dilakukan terhadap ekstrak untuk mendeteksi golongan kandungan kimianya. Selanjutnya ekstrak etanol akar Boehmeria virgata (Forst) Guill diuji aktivitasnya terhadap larva udang Artemia salina L. Hasil penelitian menunjukkan bahwa ekstrak akar Boehmeria virgata (Forst) Guill mengandung golongan alkaloid, terpenoid, fenolik,flavanoid dan memberikan LC50 sebesar 13,095 µg/ml. Dari hasil tersebut dapat dinyatakan bahwa ekstrak etanol akar Boehmeria virgata (Forst) Guill memiliki toksisitas terhadap larva udang Artemia salina L

Investigation into image technology of timber for the assessment of structural performance of fresh-cut oak tree joints (Quercus Robur L.)
No full textThe Institution of Civil Engineers in their first Royal Charter quoted 'Civil Engineering is the art of directing the great sources of power in nature for the use and convenience of mankind'.Looking at the fundamental design and stability of the tree branch connection ('Global Joint') response to loading through biomimicry can inspire designs using infrastructure materials. This project develops the process of strain monitoring image technology on timber to analyse the mechanical behaviour of the fibres internal to a Global Joint.The Particle Image Velocimetry (PIV) is applied to images taken during British Standard structural tension tests of batten samples of timber ('Components‘) taken from an Oak tree Global Joint. A detailed process is described by which results from the PIV were extrapolated and the interpretation techniques used on the resulting contour plots. The resulting contour plot shows the impending failure of the Component as the tension is applied during the test. The sequential images taken during the test allow the strain values to be evaluated. This means the interaction of the visible timber surface fibres during testing can be analysed without the need for strain gauges or alterations to the Component.The Components are structurally analysed individually and then reformed back to present the natural structural design of the Global Joint. The PIV strain results from the tension tested Components are combined with the peak stress values to find the structural performance of the interior of the Global Joint. This re-formation enables the analysis of the natural structural design facilitating the review of the internal workings
