    Pressure-induced phase transitions inL-alanine, revisited (2010)
    International Union of Crystallography
    Details
    Publication Date: 2010-07-12
    Description: The effect of pressure on L-alanine has been studied by X-ray powder diffraction (up to 12.3 GPa), single-crystal X-ray diffraction, Raman spectroscopy and optical microscopy (up to ∼ 6 GPa). No structural phase transitions have been observed. At ∼ 2 GPa the cell parametersaandbbecome accidentally equal to each other, but without a change in space-group symmetry. Neither of two transitions reported by others (to a tetragonal phase at ∼ 2 GPa and to a monoclinic phase at ∼ 9 GPa) was observed. The changes in cell parameters were continuous up to the highest measured pressures and the cells remained orthorhombic. Some important changes in the intermolecular interactions occur, which also manifest themselves in the Raman spectra. Two new orthorhombic phases could be crystallized from a MeOH/EtOH/H2O pressure-transmitting mixture in the pressure range 0.8–4.7 GPa, but only if the sample was kept at these pressures for at least 1–2 d. The new phases converted back to L-alanine on decompression. Judging from the Raman spectra and cell parameters, the new phases are most probably not L-alanine but its solvates.

    Estructuras reproductoras y epífitas del género Avrainvillea en aguas cubanas (2012)
    Details
    Publication Date: 2021-05-19
    Description: Se describen las estructuras reproductivas en Avrainvillea elliottii A. Gepp et E. S. Gepp, A. longicaulis f. laxa D. S. Littler et M. M. Littler y A. digitata Littler et Littler para aguas cubanas. Se revisaron materiales de herbario del género Avrainvillea, así como ejemplares de reciente colecta y se registraron un total de 41 táxones, 23 Rhodopyta, 4 Ochrophyta y 14 Chlorophyta como epífitas. A. levis Howe presentó como epífitas a miembros de su misma especie, tanto en la lámina como en la porción apical del estipe. Los rizoides pegados a los talos epifitos de A. levis tiene forma de disco. El estipe fue la región del talo que presentó el mayor número de especies epífitas. Se adicionan siete especies de algas marinas a la flora ficológica de Cuba: Rhodogorgon ramosissima N. Norris et Bucher, Botryocladia spinulifera W. R. Taylor et I. A. Abbott, Ceratodictyon scoparium (Mont. et Millardet) R.E. Norris, Ulva rigida C. Agardh, Caulerpa prolifera f. obovata (J. Agardh) Weber Bosse, H. monile f. robusta (Børgesen) Collins et Herv., y Udotea cyathiformis var. cyathiformis f. infundibulum (J. Agardh) D. S. Littler et M.M. Littler.Details of reproductive structures in Avrainvillea elliottii A. Gepp et E. S. Gepp, A. longicaulis f. laxa D. S. Littler et M. M. Littler and A. digitata Littler et Little rare described for first time in Cuban water. Plentiful herbarium samples of Avrainvillea and recently collected material are checked. 41 Epiphyte taxa were recorded: 23 Rhodopyta, 4 Ochrophyta and 14 Chlorophyta. Avrainvillea levis Howe evidenced had growing on its blades or the ends of its stipes specimens of its own specie. Rhizoid the attachment structure in the epiphyte thallus of A.levis has the shape of a disc. The stipe showed the largest number of epiphyt species. Seven marine algae species: Rhodogorgon ramosissima N. Norris et Bucher, Botryocladia spinulifera W. R. Taylor et I. A. Abbott, Ceratodictyon scoparium (Mont. et Millardet) R.E. Norris, Ulva rigida C. Agardh, Caulerpa prolifera f. obovata (J. Agardh) Weber Bosse, H. monile f. robusta (Børgesen) Collins et Herv., and Udotea cyathiformis var. cyathiformis f. infundibulum (J.

    Capturado el camarón tigre Penaeus monodon (Fabricius, 1798) en las costas de Cuba (2013)
    Details
    Publication Date: 2021-05-19
    Description: Se identificó una especie de camarón exótico como Penaeus monodon, camarón tigre gigante, mediante tres ejemplares hembras capturados en lagunas costeras de Tunas de Zaza, golfo de Ana María, Cuba. La talla varió entre 270 mm a 290 mm de longitud total (Lt), con un peso entre 140 g a 230 g. La presencia de la especie significa una adaptación a las aguas cubanas y constituye una perspectiva positiva para su cultivo.
    Description: It was identified an exotic shrimp species as Penaeus monodon, the giant tiger shrimp, by means of 3 females captured in coastal lagoons of Júcaro, golf of Ana María, Cuba. The length was from 270 mm to 290 mm total length (Lt) weigh between 140 g to 230 g. The presences of the species represented an adaptation to Cuban waters and constitute a positive perspective for shrimp culture.
