Yield development of flax varieties and lines within variable environment in Latvia
2015
Flax is the multiple purpose crop cultivated in temperate region. Seeds of oil flax recently became important constituent for many industrial applications, such as pharmacy, medicine, food production <em>etc.</em> and have high prospective for use in Latvia. Understanding the underlying processes that limit seed yield in flax is major with respect to enhancing the breeding of flax for yield improvements. The aim of study was evaluated 29 flax varieties and lines (including 20 Latvian origins) plasticity of seed yield production in changeable environmental conditions. The experiment was carried out in the Agricultural Scientific Centre of Latgale on field trials over the period 2…
Vitrification of Immature Porcine Oocytes: Effects of Lipid Droplets, Temperature, Cytoskeleton, and Addition and Removal of Cryoprotectant
1998
Three experiments were conducted to investigate the effects of single-step and stepwise exposure to and removal of cryoprotectant, of temperature, and of a cytoskeletal relaxant on the development of germinal vesicle porcine oocytes to the M-II stage. In experiment I, noncooled cumulus-oocyte complexes (COCs) were treated using single-step/stepwise exposure to ethylene glycol (EG) and removal at 23 or 42 degrees C. Stepwise exposure to EG and dilution at 42 degrees C were found to have a positive effect on the COC developmental rate. In experiment II, also without cooling, COCs were treated with Cytochalasin B at 42 degrees C using single-step and stepwise protocols of exposure to and remov…
A comparative study of mechanical properties of fresh and frozen-thawed porcine intervertebral discs in a bioreactor environment
2016
Abstract Limited availability of fresh intervertebral discs (IVDs) necessitates the use of frozen-thawed samples in biomechanical investigations. Several authors have reported the mechanical properties of frozen-thawed IVDs, but few studies have investigated the effects of storage temperature and cooling rate. The validity and reliability of the applied freezing-thawing procedures are still relatively unknown. The study aims to compare the mechanical responses of fresh porcine IVDs and porcine IVDs, which were frozen at different freezing temperatures with a controlled-rate cooling process and then thawed. The specimens were obtained from pigs aged 6 months. A total of 18 functional spine u…
Los otros trabajadores agrícolas transnacionales: una red de injertadores mexicanos
2019
La globalización del régimen agroalimentario ha detonado una serie de flujos migratorios transnacionales. Los más estudiados han sido los de los jornaleros de temporada que realizan los trabajos más arduos, precarios y estacionales. Los trabajadores transnacionales especializados tanto en el campo como en las diversas actividades requeridas para una industria vitivinícola globalizada no han sido estudiados. Este artículo aborda el estudio de una red de trabajadores agrícolas especializados, los injertadores. Se estudia el origen de la red en el condado de Napa y su ampliación y consolidación que ha llevado a estos trabajadores a diferentes países y continentes. Se analizan las característic…
El arquitecto Rafael Guastavino (1842-1908): obra en cuatro actos
2018
[EN] This text presents extensive new information on the figure of architect Rafael Guastavino Moreno (1842-1908), those around him, and his personal and family relationships with architecture. It also examines other artistic fields and trades such as music, carpentry and winemaking, all of which influenced and obtained feedback for Guastavino¿s architecture within the historical, political and economic situation of the three places where he lived in Spain: Valencia, Barcelona and Almudévar (Huesca), before emigrating to the United States of America, where his successful professional career as an architect is widely recognized in the literature

Pulsed-field gel electrophoresis for the discrimination of Oenococcus oeni isolates from different wine-growing regions in Germany
2008
Reliable techniques are needed for the identification individual Oenococcus oeni strains with desirable flavor characteristics and to monitor the survival and contribution of inoculated and indigenous bacteria. Therefore, we investigated the suitability of pulsed-field gel electrophoresis (PFGE) for the discrimination of 65 O. oeni isolates from six different wine-producing regions in Germany. Among the restriction enzymes tested, genomic DNA digestions with Sfi I were most effective by displaying 56 (86%) different banding profiles. Our results underline the high capacity of PFGE for strain identification and differentiation. Cluster analysis of the DNA restriction patterns revealed no dis…
Polyphasic study of wine Lactobacillus strains: taxonomic implications
2005
One hundred and seventy-eight lactobacilli isolated from wine were characterized by a polyphasic approach. Strains were phenotypically identified at genus and species level by classical tests including the analysis of cell morphology, homo/heterofermentative character, sugar fermentation patterns, growth at different temperatures and the optical nature of the isomer of lactic acid produced from glucose. Molecular techniques such as random amplification of polymorphic DNA (RAPD), amplified 16S rDNA restriction analysis (16S-ARDRA), PFGE-RFLP and ribotyping were used to characterize strains, and their potential for identification and/or typing was evaluated. The information obtained with thes…
Lactobacillus oeni sp. nov., from wine.
2009
Ten Lactobacillus strains, previously isolated from different Bobal grape wines from the Utiel-Requena Origin Denomination of Spain, were characterized phylogenetically, genotypically and phenotypically. The 16S rRNA genes were sequenced and phylogenetic analysis showed that they form a tight phylogenetic clade that is closely related to reference strains Lactobacillus satsumensis NRIC 0604T, ‘Lactobacillus uvarum’ 8 and Lactobacillus mali DSM 20444T. DNA–DNA hybridization results confirmed the separation of the strains from other Lactobacillus species. Genotypically, the strains could be differentiated from their closest neighbours by 16S amplified rDNA restriction analysis and random ampl…
Yeast Population Dynamics during the Fermentation and Biological Aging of Sherry Wines
2001
ABSTRACTMolecular and physiological analyses were used to study the evolution of the yeast population, from alcoholic fermentation to biological aging in the process of “fino” sherry wine making. The four races of “flor”Saccharomyces cerevisiae (beticus, cheresiensis, montuliensis, androuxii) exhibited identical restriction patterns for the region spanning the internal transcribed spacers 1 and 2 (ITS-1 and ITS-2) and the 5.8S rRNA gene, but this pattern was different, from those exhibited by non-florS. cerevisiaestrains. This flor-specific pattern was detected only after wines were fortified, never during alcoholic fermentation, and all the strains isolated from the velum exhibited the typ…
