Processing Of Marine Products: Sustainability, Competitiveness And Financial Viability Of The Canned Food Industry In Spain

For many decades Spain has been an important fish producer, the fact of which has created an important fish product processing sector. The main sub-sector is the canned food industry; in fact, Spain is the main canned fish and seafood producer in the EU. This paper studies the economic and financial structure of the canned food industry in Galicia, a region where the majority of the sector is located. The study is presented from the point of view of a prospective increase in demand and the risks associated with greater international competition, which obliges companies in the sector to apply more competitive strategies in order to guarantee the activitys future, both from the perspectives of access to consumers as well as business organisation and scale. The result will impact on the regional economy and on the way in which fishing resources are dealt with

The Effect Of Dimension Companies On The Level Of Debt: A Study Of The Fishing Industry In Spain

The present concern that exists in the economy on account of the high level of debt facing non-financial companies in Spain also exists in the fish and seafood processing industry, particularly to the extent that it might affect the fisheries sector as a whole. Given that Spain has generated an important processing sector and has become the main producer of canned fish and seafood in the EU, it is undoubtedly a pertinent case of reference to analyse this problem.  Along these lines, this study specifically looks at the economic structure and financial viability of the canning industry in Spain’s largest area of production (Galicia), analysing the possible interrelationships that may exist between debt levels and the business structure in this sector of the economy. Furthermore, the study is carried out in a scenario of increased demand and of risks associated with international competition, which makes the implementation of competitive strategies to guarantee the future of this activity recommendable. The results obtained show the existence of a close relationship between the size of the companies and the debt level

The “Good,” the “Bad,” and the Queer Invisible: The Los Angeles May Day Queer Contingent

This article explores the evolution of the May Day Queer Contingent (MDQC) as a part of the annual Los Angeles May Day march. The MDQC is a notable example of the political mobilization led by queer women and transgender activists of color of the LGBTQ community, as it relates to the struggle for immigrant rights. Offering reflections from founders and key organizers, this paper considers the development of the MDQC; its engagement with other groups; intersectionality and queer women of color feminisms as a political project to confront a heteropatriarchal immigration reform movement

Generation of mice with longer and better preserved telomeres in the absence of genetic manipulations

Although telomere length is genetically determined, mouse embryonic stem (ES) cells with telomeres of twice the normal size have been generated. Here, we use such ES cells with 'hyper-long' telomeres, which also express green fluorescent protein (GFP), to generate chimaeric mice containing cells with both hyper-long and normal telomeres. We show that chimaeric mice contain GFP-positive cells in all mouse tissues, display normal tissue histology and normal survival. Both hyper-long and normal telomeres shorten with age, but GFP-positive cells retain longer telomeres as mice age. Chimaeric mice with hyper-long telomeres also accumulate fewer cells with short telomeres and less DNA damage with age, and express lower levels of p53. In highly renewing compartments, such as the blood, cells with hyper-long telomeres are longitudinally maintained or enriched with age. We further show that wound-healing rates in the skin are increased in chimaeric mice. Our work demonstrates that mice with functional, longer and better preserved telomeres can be generated without the need for genetic manipulations, such as TERT overexpression.M. A.

Iron Deprivation in Synechocystis : Inference of Pathways, Non-coding RNAs, and Regulatory Elements from Comprehensive Expression Profiling

Iron is an essential cofactor in many metabolic reactions. Mechanisms controlling iron homeostasis need to respond rapidly to changes in extracellular conditions, but they must also keep the concentration of intracellular iron under strict control to avoid the generation of damaging reactive oxygen species. Due to its role as a redox carrier in photosynthesis, the iron quota in cyanobacteria is about 10 times higher than in model enterobacteria. The molecular details of how such a high quota is regulated are obscure. Here we present experiments that shed light on the iron regulatory system in cyanobacteria. We measured time-resolved changes in gene expression after iron depletion in the cyanobacterium Synechocystis sp. PCC 6803 using a comprehensive microarray platform, monitoring both protein-coding and non-coding transcripts. In total, less than a fifth of all protein-coding genes were differentially expressed during the first 72 hr. Many of these proteins are associated with iron transport, photosynthesis, or ATP synthesis. Comparing our data with three previous studies, we identified a core set of 28 genes involved in iron stress response. Among them were genes important for assimilation of inorganic carbon, suggesting a link between the carbon and iron regulatory networks. Nine of the 28 genes have unknown functions and constitute key targets for further functional analysis. Statistical and clustering analyses identified 10 small RNAs, 62 antisense RNAs, four 59UTRs, and seven intragenic elements as potential novel components of the iron regulatory network in Synechocystis. Hence, our genome-wide expression profiling indicates an unprecedented complexity in the iron regulatory network of cyanobacteria.Portuguese Fundacao para a Ciencia e a Tecnologia (FCT) [PTDC/BIA-MIC/101036/2008]; Deutsche Forschungsgemeinschaft (DFG) Focus program "Sensory and regulatory RNAs in Prokaryotes [SPP1258]; FCT [PEst-OE/EQB/LA0023/2011]info:eu-repo/semantics/publishedVersio

Double aluminum recovery and its reuse in wastewater treatment

This work evaluates the use of aluminum contained in the aluminum–polyethylene films as anodic electrodes using the electrocoagulation technique to reduce the pollutant contents of industrial wastewater quickly and effectively. Thermal treatment at 500 °C produces pure aluminum (according to TGA and SEM/EDS analysis) which is used to construct aluminum disks (applying 6 tons/cm2 of pressure). Aluminum disks are used as cathodes and anodes in an electrochemical cell. The current density applied in the recovered Al electrodes was 12 mA cm−2, and the maximum COD reduction of wastewater was 77 % at 25 min of treatment. The color and turbidity reductions are 87 and 90 %, respectively. The resulting sludge of wastewater treatment was thermally treated and a second aluminum recovery was reached; since the organic material present in the sludge was removed by the high temperature, the obtained aluminum was pure enough for its reuse. The use of aluminum–polyethylene films as electrodes in the electrocoagulation process contributes to the pollutant removal without the addition of chemical reagents or changing the pH, so it is both effective and environmentally friendly.UAEM-UNAM CONACY

Multiple linear regression analysis of factors affecting the consumption

Econometrics provides the researchers with methods, theoretical basements, and procedures that allow the formulation and estimation of economic models that explain the study variable during a reference time period, as well as making predictions about the behavior of the studied reality based on the explanatory variables. The entire process, analyzed from econometrics after having formulated and estimated the model, leads to a very important phase: the statistical validation, which helps the researcher to ensure that the model satisfactorily passes a series of tests. These tests will allow the use of the model not just to explain the behavior of the independent variable under study, but to make predictions based on scenarios of occurrence based on those explanatory variables included in the model, offering a theoretical-practical support to formulate policies related to the studied phenomenon. This research aims to generate the first elements to know the private consumption behavior in India in the period from 2012 to 201

Mediterranean species of Caulerpa are polyploid with smaller genomes in the invasive ones

Caulerpa species are marine green algae, which often act as invasive species with rapid clonal proliferation when growing outside their native biogeographical borders. Despite many publications on the genetics and ecology of Caulerpa species, their life history and ploidy levels are still to be resolved and are the subject of large controversy. While some authors claimed that the thallus found in nature has a haplodiplobiontic life cycle with heteromorphic alternation of generations, other authors claimed a diploid or haploid life cycle with only one generation involved. DAPI-staining with image analysis and microspectrophotometry were used to estimate relative nuclear DNA contents in three species of Caulerpa from the Mediterranean, at individual, population and species levels. Results show that ploidy levels and genome size vary in these three Caulerpa species, with a reduction in genome size for the invasive ones. Caulerpa species in the Mediterranean are polyploids in different life history phases; all sampled C. taxifolia and C. racemosa var. cylindracea were in haplophasic phase, but in C. prolifera, the native species, individuals were found in both diplophasic and haplophasic phases. Different levels of endopolyploidy were found in both C. prolifera and C. racemosa var. cylindracea. Life history is elucidated for the Mediterranean C. prolifera and it is hypothesized that haplophasic dominance in C. racemosa var. cylindracea and C. taxifolia is a beneficial trait for their invasive strategies
