    The life and personality of Johann Gregor Mendel (1822-1884), the founder of scientific genetics, are reviewed against the contemporary background of his times. At the end are weighed the benefits for Mendel (as charged by Sir Ronald Fisher) to have documented his results on hand of falsified data. Mendel was born into a humble farm family in the "Kuhländchen", then a predominantly German area of Northern Moravia. On the basis of great gifts Mendel was able to begin higher studies; however, he found himself in serious financial difficulties because of his father's accident and incapacitation. His hardships engendered illness which threatened continuation and completion of his studies until he was afforded the chance of absolving successfully theological studies as an Augustinian monk in the famous chapter of St. Thomas in Altbrünn (Staré Brno). Psychosomatic indisposition made Mendel unfit for practical pastoral duties. Thus, he was directed to teach but without appropriate state certification; an attempt to pass such an examination failed. At that point he was sent to the University of Vienna for a 2-year course of studies, with emphasis on physics and botany, to prepare him for the exam. His scientific and methodologic training enabled him to plan studies of the laws of inheritance, which had begun to interest him already during his theology training, and to choose the appropriate experimental plant. In 1865, after 12 years of systematic investigations on peas, he presented his results in the famous paper "Versuche über Pflanzenhybriden." Three years after his return from Vienna he failed to attain his teaching certification a second time. Only by virtue of his exceptional qualifications did he continue to function as a Supplementary Professor of Physics and Natural History in the two lowest classes of a secondary school. In 1868 he was elected Abbot of his chapter, and freed from teaching duties, was able to pursue his many scientific interests with greater

    Gregor Mendel, an Augustinian monk and part-time school teacher, undertook a series of brilliant hybridisation experiments with garden peas between 1857 and 1864 in the monastery gardens and, using statistical methods for the first time in biology, established the laws of heredity, thereby establishing the discipline of genetics.

    The discoveries of Gregor Mendel, as described by Mendel in his 1866 paper Versuche uber Pflanzen-Hybriden (Experiments on plant hybrids), can be used in undergraduate genetics and biology courses to engage students about specific nature of science characteristics and their relationship to four of his major contributions to genetics. The use of primary source literature as an instructional tool to enhance genetics students' understanding of the nature of science helps students more clearly understand how scientists work and how the science of genetics has evolved as a discipline. We offer a historical background of how the nature of science developed as a concept and show how Mendel's investigations of heredity can enrich biology and genetics courses by exemplifying the nature of science. © 2010 The Authors.

    At almost 90 years of age, we have lost the author of the founding historical works on Johann Gregor Mendel. Vítězslav Orel served for almost 30 years as the editor of the journal Folia Mendeliana. His work was beset by the wider problems associated with Mendel's recognition in the Communist Bloc, and by the way in which narratives of the history of science could be co-opted into the service of Cold War and post-Cold War political agendas. Orel played a key role in the organization of the Mendel symposium of 1965 in Brno, and has made a strong contribution to the rehabilitation of genetics generally, and to championing the work of Johann Gregor Mendel in particular. With Jaroslav Kříženecký, he cofounded the Mendelianum in Brno, which for decades has served as an intellectual bridge between the East and West. Orel's involvement with this institution exposed him to dangers both during and after the Cold War.

In 2015 we are commemorating 150 years since Mendel's lectures, which he presented in Brno on February and March 1865. The main aim of the conference was to create a periodical possibility for students, academics and researchers to exchange their ideas and novel research methods.  .

  7. From the peas of Gregor Mendel to the human genome and beyond

    In the middle of the 19th century, Gregor Mendel conducted his experiments with peas. This took place in the Augustinian monastery in Brno (now the Czech Republic), where he was the abbot. These experiments laid the foundations of modern genetics. At around the same time Charles Darwin formulated his theory of evolution. Through their work, these two men inaugurated the age of modern biology. The next most important step came in 1953 when James Watson and Francis Crick solved the elusive DNA structure. Since then methods for ‘reading’ genetic information have developed quickly, and genomes of many organisms have been analysed, including our own. The human genome consists of 3 billion letters (nucleotides) and it comprises approximately 25,000 genes. The smallest natural genome is the genome of Mycoplasma genitalium. It consists of a mere 500,000 nucleotides and is composed of 500 genes. Yet, mycoplasma is capable of a completely independent life. It would appear from this fact that basic life itself is no...

    2007-06-01

    Abstract: A philosopher and teacher, F. M. (Ladimir) Klacel (1808-1882), educated in what is now the Czech Republic, developed his own explanation for the origin and interaction of living organisms. Klácel, a member of the Augustinian Monastery in Brno, influenced his younger colleague, Friar Gregor Mendel, who went on to formulate concepts in heredity that are still recognized for their profound insight. A mutual interest in the natural sciences of these two friends provided a basis for their discussions of the relationship between religion, evolution, and society. Klacel's outspoken defense of his proposals caused him to lose favor with both the Church and the authorities, and he immigrated to America in 1869. His failing health and inability to communicate with the English-speaking populace, unfortunately, limited his influence in his new environs. In this paper we trace the roots of Klacel's philosophy and elucidate his incorporation of ideas from Hegel, Darwin, and others. An investigation of Klacel's recipe for a successful society reveals his belief in the universality of life and his optimistic hope for human achievement.

  11. The Full Breadth of Mendel's Genetics.

    2016-12-01

    Gregor Mendel's "Experiments on Plant Hybrids" (1865/1866), published 150 years ago, is without doubt one of the most brilliant works in biology. Curiously, Mendel's later studies on Hieracium (hawkweed) are usually seen as a frustrating failure, because it is assumed that they were intended to confirm the segregation ratios he found in Pisum Had this been his intention, such a confirmation would have failed, since, unknown to Mendel, Hieracium species mostly reproduce by means of clonal seeds (apomixis). Here we show that this assumption arises from a misunderstanding that could be explained by a missing page in Mendel's first letter to Carl Nägeli. Mendel's writings clearly indicate his interest in "constant hybrids," hybrids which do not segregate, and which were "essentially different" from "variable hybrids" such as in Pisum After the Pisum studies, Mendel worked mainly on Hieracium for 7 years where he found constant hybrids and some great surprises. He also continued to explore variable hybrids; both variable and constant hybrids were of interest to Mendel with respect to inheritance and to species evolution. Mendel considered that their similarities and differences might provide deep insights and that their differing behaviors were "individual manifestations of a higher more fundamental law."

  12. From Mendel's discovery on pea to today's plant genetics and breeding : Commemorating the 150th anniversary of the reading of Mendel's discovery.

    This work discusses several selected topics of plant genetics and breeding in relation to the 150th anniversary of the seminal work of Gregor Johann Mendel. In 2015, we celebrated the 150th anniversary of the presentation of the seminal work of Gregor Johann Mendel. While Darwin's theory of evolution was based on differential survival and differential reproductive success, Mendel's theory of heredity relies on equality and stability throughout all stages of the life cycle. Darwin's concepts were continuous variation and "soft" heredity; Mendel espoused discontinuous variation and "hard" heredity. Thus, the combination of Mendelian genetics with Darwin's theory of natural selection was the process that resulted in the modern synthesis of evolutionary biology. Although biology, genetics, and genomics have been revolutionized in recent years, modern genetics will forever rely on simple principles founded on pea breeding using seven single gene characters. Purposeful use of mutants to study gene function is one of the essential tools of modern genetics. Today, over 100 plant species genomes have been sequenced. Mapping populations and their use in segregation of molecular markers and marker-trait association to map and isolate genes, were developed on the basis of Mendel's work. Genome-wide or genomic selection is a recent approach for the development of improved breeding lines. The analysis of complex traits has been enhanced by high-throughput phenotyping and developments in statistical and modeling methods for the analysis of phenotypic data. Introgression of novel alleles from landraces and wild relatives widens genetic diversity and improves traits; transgenic methodologies allow for the introduction of novel genes from diverse sources, and gene editing approaches offer possibilities to manipulate gene in a precise manner.

    In this review, we explore Gregor Mendel's hybridization experiments with Hieracium , update current knowledge on apomictic reproduction and describe approaches now being used to develop true-breeding hybrid crops. From our perspective, it is easy to conclude that Gregor Mendel's work on pea was insightful, but his peers clearly did not regard it as being either very convincing or of much importance. One apparent criticism was that his findings only applied to pea. We know from a letter he wrote to Carl von Nägeli, a leading botanist, that he believed he needed to "verify, with other plants, the results obtained with Pisum". For this purpose, Mendel adopted Hieracium subgenus Pilosella, a phenotypically diverse taxon under botanical study at the time. What Mendel could not have known, however, is that the majority of these plants are not sexual plants like pea, but instead are facultatively apomictic. In these forms, the majority of seed arises asexually, and such progeny are, therefore, clones of the maternal parent. Mendel obtained very few hybrids in his Hieracium crosses, yet we calculate that he probably emasculated in excess of 5000 Hieracium florets to even obtain the numbers he did. Despite that effort, he was perplexed by the results, and they ultimately led him to conclude that "the hybrids of Hieracium show a behaviour exactly opposite to those of Pisum". Apomixis is now a topic of intense research interest, and in an ironic twist of history, Hieracium subgenus Pilosella has been developed as a molecular model to study this trait. In this paper, we explore further Mendel's hybridization experiments with Hieracium, update current knowledge on apomictic reproduction and describe approaches now being used to develop true-breeding hybrid crops.

  14. Mendel in the kitchen a scientist's view of genetically modified foods

    While European restaurants race to footnote menus, reassuring concerned gourmands that no genetically modified ingredients were used in the preparation of their food, starving populations around the world eagerly await the next harvest of scientifically improved crops. "Mendel in the Kitchen" provides a clear and balanced picture of this tangled, tricky (and very timely) topic. Any farmer you talk to, could tell you that we've been playing with the genetic makeup of our food for millennia, carefully coaxing nature to do our bidding. The practice officially dates back to Gregor Mendel - who was not a renowned scientist, but a 19th century Augustinian monk. Mendel spent many hours toiling in his garden, testing and cultivating more than 28,000 pea plants, selectively determining very specific characteristics of the peas that were produced, ultimately giving birth to the idea of heredity - and the now very common practice of artificially modifying our food. But as science takes the helm, steering common field pr...

    This article proposes a previously unpublished French translation of a petition, in German, addressed by six Augustinian friars to the Constitutional Parliament of Vienna in the revolutionary year 1848. The petition states that members of religious orders are deprived of civil rights and demands that they be given citizenship ; it also contains a bitter attack on the monastic institution. We suggest that Mendel was the author of this text, which he signed and actually hand-wrote.

    One hundred and fifty years ago, Gregor Mendel investigated the segregation of seven traits in pea (Pisum sativum) and established the law of segregation and the law of independent assortment in genetics. After the two laws of genetics were rediscovered in 1900, the seven traits have been extensively investigated in the fields of plant physiology and biochemistry as well as in the cell and molecular levels. Recently, with the development of molecular technology in genetics, four genes for seed shape (R), stem length (Le), cotyledon colour (I), and flower colour (A) have been cloned and sequenced; and another three genes for immature pod colour (Gp), fasciation (Fa) and pod form (V) have been located in the linkage groups, respectively. The identification and cloning of the four Mendel's genes will help deeply understand the basic concept of gene in many respects: like the diversity of gene function, the different origins for gene mutation in molecular level, and the molecular nature of a dominant gene or a recessive gene. In teaching of genetics, the introduction of most recent research advancements of cloning of Mendel's genes to the students and the interpretation of the Mendel's laws in molecular level will help students promote their learning interests in genetics and help students grasp the whole content from classical genetics to molecular genetics and the developmental direction of this subject.

    2016-01-01

    The origins of genetics are to be found in Gregor Mendel's memoir on plant hybridization (1865). However, the word 'genetics' was only coined in 1906, to designate the new science of heredity. Founded upon the Mendelian method for analyzing the products of crosses, this science is distinguished by its explicit purpose of being a general 'science of heredity', and by the introduction of totally new biological concepts (in particular those of gene, genotype, and phenotype). In the 1910s, Mendelian genetics fused with the chromosomal theory of inheritance, giving rise to what is still called 'classical genetics'. Within this framework, the gene is simultaneously a unit of function and transmission, a unit of recombination, and of mutation. Until the early 1950s, these concepts of the gene coincided. But when DNA was found to be the material basis of inheritance, this congruence dissolved. Then began the venture of molecular biology, which has never stopped revealing the complexity of the way in which hereditary material functions. Copyright © 2016 Académie des sciences.

It notes the long-established tests for the validity of any explanations that purport to explain observations obtained by experiment. Application of these tests to Mendel's paper shows that the arguments he used to explain his observations were internally consistent but were, on one crucial issue, implausible. The same tests are applied to the currently accepted explanation for Mendel's observations. The currently favoured explanation for Mendel's observations is untenable. It misrepresents Mendel, fails to distinguish between the parameters and the variables of any system of interacting components, its arguments are inconsistent, it repeats the implausibility in Mendel's paper, fails to give a rational explanation for his observed 3:1 trait ratio and cannot explain why this ratio is not always observed in experimental practice.

    The 1.5 m telescope GREGOR opens a new window to the understanding of solar small-scale magnetism. The first light instrumentation includes the Gregor Fabry Pérot Interferometer (GFPI), a filter spectro-polarimeter for the visible wavelength range, the GRating Infrared Spectro-polarimeter (GRIS) and the Broad-Band Imager (BBI). The excellent performance of the first two instruments has already been demonstrated at the Vacuum Tower Telescope. GREGOR is Europe's largest solar telescope and number 3 in the world. Its all-reflective Gregory design provides a large wavelength coverage from the near UV up to at least 5 microns. The field of view has a diameter of 150 arcsec. GREGOR is equipped with a high-order adaptive optics system, with a subaperture size of 10 cm, and a deformable mirror with 256 actuators. The science goals are focused on, but not limited to, solar magnetism. GREGOR allows us to measure the emergence and disappearance of magnetic flux at the solar surface at spatial scales well below 100 km. Thanks to its spectro-polarimetric capabilities, GREGOR will measure the interaction between the plasma flows, different kinds of waves, and the magnetic field. This will foster our understanding of the processes that heat the chromosphere and the outer layers of the solar atmosphere. Observations of the surface magnetic field at very small spatial scales will shed light on the variability of the solar brightness.

    Full Text Available In 1939 N.I. Ermolaeva published the results of an experiment which repeated parts of Mendel's classical experiments. On the basis of her experiment she concluded that Mendel's principle that self-pollination of hybrid plants gave rise to segregation proportions 3:1 was false. The great probability theorist A.N. Kolmogorov reviewed Ermolaeva's data using a test, now referred to as Kolmogorov's, or Kolmogorov-Smirnov, test, which he had proposed in 1933. He found, contrary to Ermolaeva, that her results clearly confirmed Mendel's principle. This paper shows that there were methodological flaws in Kolmogorov's statistical analysis and presents a substantially adjusted approach, which confirms his conclusions. Some historical commentary on the Lysenko-era background is given, to illuminate the relationship of the disciplines of genetics and statistics in the struggle against the prevailing politically-correct pseudoscience in the Soviet Union. There is a Brazilian connection through the person of Th. Dobzhansky.

    Chromosomal crossover is a biological mechanism to combine parental traits. It is perhaps the first mechanism ever taught in any introductory biology class. The formulation of crossover, and resulting recombination, came about 100 years after Mendel's famous experiments. To a great extent, this formulation is consistent with the basic genetic findings of Mendel. More importantly, it provides a mathematical insight for his two laws (and corrects them). From a mathematical perspective, and while it retains similarities, genetic recombination guarantees diversity so that we do not rapidly converge to the same being. It is this diversity that made the study of biology possible. In particular, the problem of genetic mapping and linkage-one of the first efforts towards a computational approach to biology-relies heavily on the mathematical foundation of crossover and recombination. Nevertheless, as students we often overlook the mathematics of these phenomena. Emphasizing the mathematical aspect of Mendel's laws through crossover and recombination will prepare the students to make an early realization that biology, in addition to being experimental, IS a computational science. This can serve as a first step towards a broader curricular transformation in teaching biological sciences. I will show that a simple and modern treatment of Mendel's laws using a Markov chain will make this step possible, and it will only require basic college-level probability and calculus. My personal teaching experience confirms that students WANT to know Markov chains because they hear about them from bioinformaticists all the time. This entire exposition is based on three homework problems that I designed for a course in computational biology. A typical reader is, therefore, an instructional staff member or a student in a computational field (e.g., computer science, mathematics, statistics, computational biology, bioinformatics). However, other students may easily follow by omitting the

    Singh, Rama S

    2015-09-01

    Mendel is credited for discovering Laws of Heredity, but his work has come under criticism on three grounds: for possible falsification of data to fit his expectations, for getting undue credit for the laws of heredity without having ideas of segregation and independent assortment, and for being interested in the development of hybrids rather than in the laws of heredity. I present a brief review of these criticisms and conclude that Mendel deserved to be called the father of genetics even if he may not, and most likely did not, have clear ideas of segregation and particulate determiners as we know them now. I argue that neither Mendel understood the evolutionary significance of his findings for the problem of genetic variation, nor would Darwin have understood their significance had he read Mendel's paper. I argue that the limits to imagination, in both cases, came from their mental framework being shaped by existing paradigms-blending inheritance in the case of Darwin, hybrid development in the case of Mendel. Like Einstein, Darwin's natural selection was deterministic; like Niels Bohr, Mendel's Laws were probabilistic-based on random segregation of trait-determining "factors". Unlike Einstein who understood quantum mechanics, Darwin would have been at a loss with Mendel's paper with no guide to turn to. Geniuses in their imaginations are like heat-seeking missiles locked-in with their targets of deep interests and they generally see things in one dimension only. Imagination has limits; unaided imagination is like a bird without wings--it goes nowhere.

  15. Mendel in Genetics Teaching: Some Contributions from History of Science and Articles for Teachers

    Science.gov (United States)

    El-Hani, Charbel N.

    2015-01-01

    School science descriptions about Mendel and his story are problematic because several statements that are controversial among historians of science are repeated over and over again as if they were established facts. Another problem is the neglect of other scientists working on inheritance in the second half of the nineteenth century, including Darwin, Spencer, Galton, Nägeli, Brooks, Weismann and de Vries, who paved the way for the reinterpretation of Mendel's work in 1900. These problems are often found in textbooks and are likely to be present in school science throughout the world. Here, we discuss the contributions that history of science and papers published in journals that target teachers may bring to improve how school science deals with Mendel and his contributions. Evidently the idea is not that school teachers could solve problems still under discussion in the historical literature. The point is, rather, that it is important to avoid treating Mendel's contributions as uncontroversial, mentioning, for instance, that there are ongoing debates on whether he proposed the laws named after him by appealing to invisible factors underlying phenotypic traits that are seen as the heritable potentials for those traits, and would in due time be known as genes. History of science can contribute to put the mythic Mendel into question in the science classroom, bringing school science closer to the controversies around the interpretation of his work.

    Full Text Available Article is devoted to the formation of a special legal position of privatdozentur in Russian universities 1803-1884. The author analyzes a wide range of sources: Russian university statutes, documents and publications of the Ministry of National Education, comments on the draft statute in 1862. The aufer gradually build up the whole picture of the legislation on privatdozentur in its development. Article is thematically divided into sections in which the basic aspects of the Ministry of rulemaking activities are represented. Among them: the problem of privatdozentur, requirements to occupy the post, sources of fi nancing, the rights and obligations of university lecturers. Article is preceded by a brief excursion into the history of privatdozentur and reasoning about the discrepancies in the terminology. The author comes to new conclusions that the basic legislation on university lecturers have been laid already in the Charter of the University of Dorpat in 1803, and the term «privatdozent» came into use in the late 50s. (to fix the statute in 1863. The most important step in the development of institutions was the University Statute of 1863 and the University Statute of 1884 became a closing link in the chain of transformations privatdozentur in the universities of the Russian Empire. After 1884 Russian privatdozentur continued existence in a new environment and on a new qualitive basis, resulting in a tremendous increase in the number of privatdozents. Despite all the changes occurred from 1804 to 1884, following provisions remained constant: privatdozents were university professors, who were not included in the staff, were not involved in lectures, had no salary or other regular sources of funding. Until 1884 when they took office, they had to read a public trial lecture (or two and defend a thesis pro venia legendi.

    A huge amount of data has been acquired with the GREGOR Fabry-Pérot Interferometer (GFPI), large-format facility cameras, and since 2016 with the High-resolution Fast Imager (HiFI). These data are processed in standardized procedures with the aim of providing science-ready data for the solar physics community. For this purpose, we have developed a user-friendly data reduction pipeline called ``sTools'' based on the Interactive Data Language (IDL) and licensed under creative commons license. The pipeline delivers reduced and image-reconstructed data with a minimum of user interaction. Furthermore, quick-look data are generated as well as a webpage with an overview of the observations and their statistics. All the processed data are stored online at the GREGOR GFPI and HiFI data archive of the Leibniz Institute for Astrophysics Potsdam (AIP). The principles of the pipeline are presented together with selected high-resolution spectral scans and images processed with sTools.

    This paper is concerned with the role of rational belief change theory in the philosophical understanding of experimental error. Today, philosophers seek insight about error in the investigation of specific experiments, rather than in general theories. Nevertheless, rational belief change theory adds to our understanding of just such cases: R. A. Fisher's criticism of Mendel's experiments being a case in point. After an historical introduction, the main part of this paper investigates Fisher's paper from the point of view of rational belief change theory: what changes of belief about Mendel's experiment does Fisher go through and with what justification. It leads to surprising insights about what Fisher had done right and wrong, and, more generally, about the limits of statistical methods in detecting error.

    Full Text Available It is well known that Mendel chose peas as the study material for his experiments that are the cornerstone of genetics. Nonetheless, it is less known that he also experimented with other legumes although with reduced success, or that Darwin also experimented with legumes. During the first decade of the twentieth century, peas were the favorite material used to verify Mendel’s results. Although genetics after that time primarily developed using other eukaryotic organisms or microorganisms, legumes pertain to the core material that allowed Vavilov to develop his Law of Homologous Series in Variation. They have also been used as a model to study plant-microbe symbiotic relationships that enable the fixation of atmospheric nitrogen, making them one of the biological models of the genomic age. Over the last five years, several genome sequences of cultivated legume species have been published, with many more to be made public in the upcoming years. Consequently, the amount of theoretical knowledge accumulating in this area and its application in plant breeding are increasing exponentially.Es conocido que Mendel escogió los guisantes como material para realizar los experimentos que son la piedra fundacional de la Genética. Pero es menos conocido que Mendel también experimentó con otras leguminosas con menos éxito, o que Darwin experimentó con leguminosas.

Después, la Genética se desarrolló utilizando prioritariamente otros organismos eucariotas o microorganismos. Aun así, las leguminosas forman parte de los materiales en los que Vavilov se basó para desarrollar su Ley de las Series Homólogas en la Variación.

    Algebraic discussions are developed to derive transition probabilities for a simple time-inhomogeneous birth–death process. Algebraic probability theory and Lie algebraic treatments make it easy to treat the time-inhomogeneous cases. As a result, an expression based on the Charlier polynomials is obtained, which can be considered as an extension of a famous Karlin–McGregor representation for a time-homogeneous birth–death process.

  16. The cold war context of the golden jubilee, or, why we think of mendel as the father of genetics.

    Science.gov (United States)

    Wolfe, Audra J

    2012-01-01

    In September 1950, the Genetics Society of America (GSA) dedicated its annual meeting to a "Golden Jubilee of Genetics" that celebrated the 50th anniversary of the rediscovery of Mendel's work. This program, originally intended as a small ceremony attached to the coattails of the American Institute of Biological Sciences (AIBS) meeting, turned into a publicity juggernaut that generated coverage on Mendel and the accomplishments of Western genetics in countless newspapers and radio broadcasts. The Golden Jubilee merits historical attention as both an intriguing instance of scientific commemoration and as an early example of Cold War political theatre. Instead of condemning either Lysenko or Soviet genetics, the Golden Jubilee would celebrate Mendel - and, not coincidentally, the practical achievements in plant and animal breeding his work had made possible. The American geneticists' focus on the achievements of Western genetics as both practical and theoretical, international, and, above all, non-ideological and non-controversial, was fully intended to demonstrate the success of the Western model of science to both the American public and scientists abroad at a key transition point in the Cold War. An implicit part of this article's argument, therefore, is the pervasive impact of the Cold War in unanticipated corners of postwar scientific culture.

    Full Text Available In 1865, Gregor Mendel presented the lectures 'Experiments in Plant Hybridization' concerning his results from cross-breeding experiments with different types of garden pea, performed in his monastery garden in Brno. Mendel studied easily observed pairs of opposite traits, such as purple or white flower, and discovered dominant and recessive traits. He concluded that parents pass separate and distinct factors (today called genes on to their offspring that are responsible for inherited traits. However, the scientific community did not understand that; indeed it was the beginning of what becomes genetics. The lectures published in 1866, Mendel sent to more than 30 biologists across Europe, but almost no one commented them. In the next 35 years, these papers were only three times cited. The genetics became more important at the beginning of the 20th century, when three different research groups (Hugo de Vries, Carl Erich Correns and Erich von Tschermak with their co-workers independently re-discovered Mendel's Laws of inheritance. However, as soon as the work was rediscovered, it created controversy. The closeness of Mendel's experimental observations to those predicted by his theories has led to numerous articles and ongoing debate about whether the data could have been obtained in the published form without some falsification. There have been many plausible arguments made for and against this view by a range of eminent geneticists and statisticians. Some have gone so far, as to suggest that the theories ensued from Mendel's two laws were not even correctly formulated in his original paper. The strongest supporters of Mendel's theory became biologist William Bateson and zoologist and geneticist Thomas Hunt Morgan. Morgan argued that genes are located on chromosomes and that the cells chromosomes hold the actual hereditary material, thus created what is now known as classical genetics. For his discovery concerning the role play by the chromosome in

Between 1881- 1884 the Chilean State unfolds to a foreign territory and by doing so improves its administrative skills. This reasoning will lead it to explore its authoritarian nature in Peru, where the absence of the State and of civil society allowed its political and ideological predominance.

  3. The "Mendel syndrome" in science: durability of scientific literature and its effects on bibliometric analysis of individual scientists.

    Science.gov (United States)

    Costas, Rodrigo; van Leeuwen, Thed N; van Raan, Anthony F J

    2011-10-01

    The obsolescence and "durability" of scientific literature have been important elements of debate during many years, especially regarding the proper calculation of bibliometric indicators. The effects of "delayed recognition" on impact indicators have importance and are of interest not only to bibliometricians but also among research managers and scientists themselves. It has been suggested that the "Mendel syndrome" is a potential drawback when assessing individual researchers through impact measures. If publications from particular researchers need more time than "normal" to be properly acknowledged by their colleagues, the impact of these researchers may be underestimated with common citation windows. In this paper, we answer the question whether the bibliometric indicators for scientists can be significantly affected by the Mendel syndrome. Applying a methodology developed previously for the classification of papers according to their durability (Costas et al., J Am Soc Inf Sci Technol 61(8):1564-1581, 2010a; J Am Soc Inf Sci Technol 61(2):329-339, 2010b), the scientific production of 1,064 researchers working at the Spanish Council for Scientific Research (CSIC) in three different research areas has been analyzed. Cases of potential "Mendel syndrome" are rarely found among researchers and these cases do not significantly outperform the impact of researchers with a standard pattern of reception in their citations. The analysis of durability could be included as a parameter for the consideration of the citation windows used in the bibliometric analysis of individuals.

Appl. 29 117-42), Gruenbaum (2007 Probability, Geometry and Integrable Systems ed Pinsky and Birnir vol 55 (Berkeley, CA: MSRI publication) pp. 241-60, see also arXiv math PR/0703375), Gruenbaum (2007 Dagstuhl Seminar Proc. 07461 on Numerical Methods in Structured Markov Chains ed Bini), Gruenbaum (2008 Proceedings of IWOTA) and Gruenbaum and de la Iglesia (2008 SIAM J. Matrix Anal. Appl. 30 741-63). We give here a weight matrix that makes the corresponding matrix-valued orthogonal polynomials orthogonal to each other. We also determine the polynomials themselves and thus obtain all the ingredients to apply a matrix-valued version of the Karlin-McGregor formula.

    The GREGOR Fabry-Pérot Interferometer (GFPI) is one of three first-light instruments of the German 1.5-m GREGOR solar telescope at the Observatorio del Teide, Tenerife, Spain. The GFPI allows fast narrow-band imaging and postfactum image restoration. The retrieved physical parameters will be a fundamental building block for understanding the dynamic sun and its magnetic field at spatial scales down to ˜50 km on the solar surface. The GFPI is a tunable dual-etalon system in a collimated mounting. It is designed for spectrometric and spectropolarimetric observations between 530-860 nm and 580-660 nm, respectively, and possesses a theoretical spectral resolution of R≈250,000. Large-format, high-cadence charged coupled device detectors with sophisticated computer hard- and software enable the scanning of spectral lines in time-spans equivalent to the evolution time of solar features. The field-of-view (FOV) of 50″×38″ covers a significant fraction of the typical area of active regions in the spectroscopic mode. In case of Stokes-vector spectropolarimetry, the FOV reduces to 25″×38″. The main characteristics of the GFPI including advanced and automated calibration and observing procedures are presented. Improvements in the optical design of the instrument are discussed and first observational results are shown. Finally, the first concrete ideas for the integration of a second FPI, the blue imaging solar spectrometer, are laid out, which will explore the blue spectral region below 530 nm.

    Full Text Available Genetics is the study of heredity, which means the study of genes and factors related to all aspects of genes. The scientific history of genetics began with the works of Gregor Mendel in the mid-19th century. Prior to Mendel, genetics was primarily theoretical whilst, after Mendel, the science of genetics was broadened to include experimental genetics. Developments in all fields of genetics and genetic technology in the first half of the 20th century provided a basis for the later developments. In the second half of the 20th century, the molecular background of genetics has become more understandable. Rapid technological advancements, followed by the completion of Human Genome Project, have contributed a great deal to the knowledge of genetic factors and their impact on human life and diseases. Currently, more than 1800 disease genes have been identified, more than 2000 genetic tests have become available, and in conjunction with this at least 350 biotechnology-based products have been released onto the market. Novel technologies, particularly next generation sequencing, have dramatically accelerated the pace of biological research, while at the same time increasing expectations. In this paper, a brief summary of genetic history with short explanations of most popular genetic techniques is given.

    This communication presents a prototype image slicer for the 4-m European Solar Telescope (EST) designed for the spectrograph of the 1.5-m GREGOR solar telescope (GRIS). The design of this integral field unit has been called MuSICa (Multi-Slit Image slicer based on collimator-Camera). It is a telecentric system developed specifically for the integral field, high resolution spectrograph of EST and presents multi-slit capability, reorganizing a bidimensional field of view of 80 arcsec^{2} into 8 slits, each one of them with 200 arcsec length × 0.05 arcsec width. It minimizes the number of optical components needed to fulfil this multi-slit capability, three arrays of mirrors: slicer, collimator and camera mirror arrays (the first one flat and the other two spherical). The symmetry of the layout makes it possible to overlap the pupil images associated to each part of the sliced entrance field of view. A mask with only one circular aperture is placed at the pupil position. This symmetric characteristic offers some advantages: facilitates the manufacturing process, the alignment and reduces the costs. In addition, it is compatible with two modes of operation: spectroscopic and spectro-polarimetric, offering a great versatility. The optical quality of the system is diffraction-limited. The prototype will improve the performances of GRIS at GREGOR and is part of the feasibility study of the integral field unit for the spectrographs of EST. Although MuSICa has been designed as a solar image slicer, its concept can also be applied to night-time astronomical instruments (Collados et al. 2010, Proc. SPIE, Vol. 7733, 77330H; Collados et al. 2012, AN, 333, 901; Calcines et al. 2010, Proc. SPIE, Vol. 7735, 77351X)

    In high-resolution solar physics, the volume and complexity of photometric, spectroscopic, and polarimetric ground-based data significantly increased in the last decade, reaching data acquisition rates of terabytes per hour. This is driven by the desire to capture fast processes on the Sun and the necessity for short exposure times “freezing” the atmospheric seeing, thus enabling ex post facto image restoration. Consequently, large-format and high-cadence detectors are nowadays used in solar observations to facilitate image restoration. Based on our experience during the “early science” phase with the 1.5 m GREGOR solar telescope (2014–2015) and the subsequent transition to routine observations in 2016, we describe data collection and data management tailored toward image restoration and imaging spectroscopy. We outline our approaches regarding data processing, analysis, and archiving for two of GREGOR’s post-focus instruments (see http://gregor.aip.de), i.e., the GREGOR Fabry–Pérot Interferometer (GFPI) and the newly installed High-Resolution Fast Imager (HiFI). The heterogeneous and complex nature of multidimensional data arising from high-resolution solar observations provides an intriguing but also a challenging example for “big data” in astronomy. The big data challenge has two aspects: (1) establishing a workflow for publishing the data for the whole community and beyond and (2) creating a collaborative research environment (CRE), where computationally intense data and postprocessing tools are colocated and collaborative work is enabled for scientists of multiple institutes. This requires either collaboration with a data center or frameworks and databases capable of dealing with huge data sets based on virtual observatory (VO) and other community standards and procedures.

    The Carseland-Bow River Headworks (CBRH) is a major multi-purpose water delivery system, situated in southern Alberta. It supplies water to 87,000 hectares of agricultural land and several municipalities. The system was originally built starting in 1909. It consists of diversion works on the Bow River, 65 kilometres of canal, and the McGregor and Little Bow reservoirs. In the 1950s, the system was rehabilitated by the Prairie Farm Rehabilitation Administration (PFRA), and Travers Reservoir was added in 1954. In 1973, ownership and operation of the CBRH system was turned over to Alberta Environment. In 2001, Alberta Transportation implemented a major program to rehabilitate and upgrade the CBRH system. This program included increasing the capacity of the canals and structures, and upgrading the dams to meet current dam safety guidelines. The project involved raising the north and south dams, providing an auxiliary spillway to accommodate the probable maximum flood (PMF), and rehabilitating the existing reservoir inlet and low level outlet structures. This paper discussed the abandonment of the existing low level outlet structure located within the south dam. The paper discussed the existing dams and outlet structure as well as the south dam and outlet structure. The abandonment of the existing low level outlet structure was discussed in terms of general construction; demolition; upstream conduits and gatewell; and downstream conduit. Several illustrations and photographs of the dam and the demolition were presented. It was concluded that the in-place abandonment of the existing low level outlet structure at the McGregor South Dam provides significant advantages, including eliminating the need to construct and remove an extensive cofferdam within the reservoir. 6 refs., 2 tabs., 4 figs.

  15. Exploring the nature of science through courage and purpose: a case study of Nikolai Vavilov and plant biodiversity.

    Science.gov (United States)

    Cohen, Joel I; Loskutov, Igor G

    2016-01-01

    Historical biographies facilitate teaching the 'nature of science'. This case study focuses on how Nikolai Vavilov's unrelenting sense of purpose, courage, and charismatic personality was maintained during violent revolutionary change in Russia. The rediscovery of Gregor Mendel's laws of inheritance provided Vavilov with a scientific foundation for crop improvement, this foundation was later bolstered by Vavilov's personal drive to conserve plant biodiversity. As he advanced theories and pragmatic approaches for genetic improvement and conservation of plants, political leaders in Russian came to reject Mendel's principles and eventually Vavilov's work. This rejection occurred because Joseph Stalin was desperate for a quick remedy to the famine and suffering from forced collective agriculture. Vavilov's work continued, modernizing Russian crop research while inspiring other scientists to save seeds stored in the world's first gene bank. Three themes illustrating the nature of science help examine Vavilov's life: explaining natural phenomena, uncompromising human endeavor, and revising scientific knowledge. The case study concludes with four questions to stimulate student inquiry and self-guided research. They also deepen student understanding of Vavilov's personal sacrifices to ensure use and conservation of plant biodiversity.

    Integral Field Spectroscopy is an innovative technique that is being implemented in the state-of-the-art instruments of the largest night-time telescopes, however, it is still a novelty for solar instrumentation. A new concept of image slicer, called MuSICa (Multi-Slit Image slicer based on collimator-Camera), has been designed for the integral field spectrograph of the 4-m European Solar Telescope. This communication presents an image slicer prototype of MuSICa for GRIS, the spectrograph of the 1.5-m GREGOR solar telescope located at the Observatory of El Teide. MuSICa at GRIS reorganizes a 2-D field of view of 24.5 arcsec into a slit of 0.367 arcsec width by 66.76 arcsec length distributed horizontally. It will operate together with the TIP-II polarimeter to offer high resolution integral field spectropolarimetry. It will also have a bidimensional field of view scanning system to cover a field of view up to 1 by 1 arcmin.

    2007-09-01

    A rereading of the American scientific literature on sex determination from 1902 to 1926 leads to a different understanding of the construction of the Mendelian-chromosome theory after 1910. There was significant intellectual continuity, which has not been properly appreciated, underlying this scientific "revolution." After reexamining the relationship between the ideas of key scientists, in particular Edmund B. Wilson and Thomas Hunt Morgan, I argue that, contrary to the historical literature, Wilson and Morgan did not adopt opposing views on Mendelism and sex determination. Rather, each preferred a non-Mendelian explanation of the determination of sex. Around 1910, both integrated the Mendelian and non-Mendelian theories to create a synthetic theory. One problem was the need to avoid an overly deterministic view of sex while also accepting the validity of Mendelism. Morgan's discovery of mutations on the X chromosome takes on different significance when set in the context of the debate about sex determination, and Calvin Bridges's work on sex determination is better seen as a development of Morgan's ideas, rather than a departure from them. Conclusions point to the role of synthesis within fields as a way to advance scientific theories and reflect on the relationship between synthesis and explanatory "pluralism" in biology.

    2015-01-01

    The demise of Soviet genetics in the 1930s, 40s, and 50s has stood for many as a prime example of the damage that social and political dogmatism can do when allowed to meddle in the workings of science. In particular, the story of Trofim Lysenko's rise to preeminence and the fall of Mendelian genetics in the Soviet Union has become a lasting testament to the dangers of state power and a seemingly blatant manifestation of totalitarianism in practice. In recent years, historians have begun to complicate this story. The purpose of this article is to examine the extent to which this conventional account of state power in Soviet biology, symbolized by the disappearance of Mendel, still holds true. Using middle school textbooks, encyclopedias, and pedagogical journals that were published between 1934 and 1964 this article argues that despite its efforts, the state apparatus was functionally incapable of eradicating genetics from its schools.

  5. Does genomic imprinting play a role in autoimmunity?

    Science.gov (United States)

    Camprubí, Cristina; Monk, David

    2011-01-01

    In the 19th century Gregor Mendel defined the laws of genetic inheritance by crossing different types of peas. From these results arose his principle of equivalence: the gene will have the same behaviour whether it is inherited from the mother or the father. Today, several key exceptions to this principle are known, for example sex-linked traits and genes in the mitochondrial genome, whose inheritance patterns are referred to as 'non mendelian'. A third, important exception in mammals is that of genomic imprinting, where transcripts are expressed in a monoallelic fashion from only the maternal or the paternal chromosome. In this chapter, we discuss how parent-of-origin effects and genomic imprinting may play a role in autoimmunity and speculate how imprinted miRNAs may influence the expression of many target autoimmune associated genes.

    Student motivation is correlated with learning. Douglas McGregor's Theory X and Theory Y as a basis for understanding and improving motivation in the business world can be directly applied to the science classroom. Teachers with a Theory Y perspective (students naturally want to learn) provide increased motivation for students and promote more active learning than Theory X-style teachers who do not view students as active learners. Many teachers are not aware of their Theory X/Theory Y orientation and how this bias may be impacting their interaction with students. This article explores the benefits of moving from a Theory X to a more Theory Y style of teaching. Copyright © 2004 International Union of Biochemistry and Molecular Biology, Inc.

  10. IMPLICATIONS OF X-RAY LINE VARIATIONS FOR 4U1822-371

    International Nuclear Information System (INIS)

    2011-01-01

    4U 1822-371 is one of the prototype accretion disk coronal sources with an orbital period of about 5.6 hr. The binary is viewed almost edge-on at a high inclination angle of 83 deg., which makes it a unique candidate to study binary orbital and accretion disk dynamics in high powered X-ray sources. We observed the X-ray source in 4U 1822-371 with the Chandra High Energy Transmission Grating Spectrometer for almost nine binary orbits. X-ray eclipse times provide an update of the orbital ephemeris. We find that our result follows the quadratic function implied by previous observations; however, it suggests a flatter trend. From the orbital line dynamics, we confirm the previous suggestion that recombination emission is located at the impact bulge of the accretion stream. Our observations show that the recombining plasma is confined to this region, and prove that it has to be a very thin layer on top of the accretion disk. Fe XXVI emission is detected at all phases and likely originates from the hot central corona which has optical depth <<1. The implied ionization parameters from both regions strongly suggest that the illuminating source is obscured with respect to the observer and is orders of magnitude brighter than what is actually observed. This is independently confirmed by the best fit of a flat power law with a high-energy cutoff and partial covering absorption with a covering fraction of about 50%. We discuss the implications of our findings with respect to the photoionized line emission and the spectral continuum on basic properties of the X-ray source.

    2007-03-01

    Full Text Available Biographical exhibitions are a museum practice that asks for critical consideration. Grounding the argument in critical theory, social studies and museum theory, the article explores the narrative function of objects in biographical exhibitions by addressing the social significance of objects in relation to biography and their relevance when presented into an exhibition display. Central is the concept of objects as ‘biographical relics’ that are culturally fetishized in biographical narratives. This raises questions about biographical reliability and the cultural role that such objects plays in exhibition narratives as bearers of reality and as metonymical icons of the biographical subject. The article considers examples of biographical exhibitions of diverse figures such as Gregor Mendel, Madame de Pompadour and Roland Barthes, and the role that personal items, but also portraits and photographs, play in them.

    An image slicer has been proposed for the Integral Field Spectrograph [1] of the 4-m European Solar Telescope (EST) [2] The image slicer for EST is called MuSICa (Multi-Slit Image slicer based on collimator-Camera) [3] and it is a telecentric system with diffraction limited optical quality offering the possibility to obtain high resolution Integral Field Solar Spectroscopy or Spectro-polarimetry by coupling a polarimeter after the generated slit (or slits). Considering the technical complexity of the proposed Integral Field Unit (IFU), a prototype has been designed for the GRIS spectrograph at GREGOR telescope at Teide Observatory (Tenerife), composed by the optical elements of the image slicer itself, a scanning system (to cover a larger field of view with sequential adjacent measurements) and an appropriate re-imaging system. All these subsystems are placed in a bench, specially designed to facilitate their alignment, integration and verification, and their easy installation in front of the spectrograph. This communication describes the opto-mechanical solution adopted to upgrade GRIS while ensuring repeatability between the observational modes, IFU and long-slit. Results from several tests which have been performed to validate the opto-mechanical prototypes are also presented.

    The Austrian physician Ernst Jeger born in 1884 got an all-round training in internal medicine, physiology and surgery (Vienna, London, Berlin, Breslau).

He did a lot of experimental work in this field, visited Alexis Carrel at the Rockefeller Institute (New York) in 1912 and published a comprehensive and even today astonishing book, entitled "Surgery of Vessels and Heart" (1913).

    Full Text Available A Ilustração, directed by the Portuguese Mariano Pina (1860-1899 and published between May 1884 and January 1892, was a Luso-Brazilian illustrated magazine that for most of its existence was edited and printed in Paris before being sent to its main target markets in Lisbon and Rio de Janeiro. The location of the magazine office in a city at the centre of Western intellectual life of that time enabled it to become a place of convergence and dialogue between agents and ideas from diverse nationalities. Through the analysis of some images published by A Ilustração, this article tries to shed light on the editorial and aesthetic policies of the magazine, characterized simultaneously by the assimilation of ideas coming from cultural centres like Paris and by the proposition of new ideas appropriate to the cultural realities of Portugal and Brazil.

    The 2011 outburst of Swift J1822.3–1606 was extraordinary; periodic modulations at the spin period of the underlying neutron star were clearly visible, remarkably similar to what is observed during the decaying tail of magnetar giant flares. We investigated the temporal characteristics of X-ray emission during the early phases of the outburst. We performed a periodicity search with the spectral hardness ratio (HR) and found a coherent signal near the spin period of the neutron star, but with a lag of about 3 radians. Therefore, the HR is strongly anti-correlated with the X-ray intensity, which is also seen in the giant flares. We studied the time evolution of the pulse profile and found that it evolves from a complex morphology to a much simpler shape within about a month. Pulse profile simplification also takes place during the giant flares, but on a much shorter timescale of about a few minutes. We found that the amount of energy emitted during the first 25 days of the outburst is comparable to what was detected in minutes during the decaying tail of giant flares. Based on these similarities, we suggest that the triggering mechanisms of the giant flares and the magnetar outbursts are likely the same. We propose that the trapped fireball that develops in the magnetosphere at the onset of the outburst radiates away efficiently in minutes in magnetars exhibiting giant flares, while in other magnetars, such as Swift J1822.3–1606, the efficiency of radiation of the fireball is not as high and, therefore, lasts much longer.

Nos interesará dejar asentado que tal distancia no dependió únicamente de las limitaciones materiales con las que se enfrentaron las autoridades escolares, o de las decisiones de los padres con respecto de la asistencia de sus hijos a la escuela, sino que la misma estuvo enraizada en un elemento más profundo, del orden de las representaciones, que desde muy temprano funcionó como un impedimento para la realización de la vocación educativa pretendidamente ecuménica de las élites argentinas. De hecho, las posturas educativas universalistas convivieron con ostras que rechazaban la posibilidad e incluso la conveniencia de que todos los niños se educaran en escuelas comunes, aparente contradicción que atravesó los discursos y las prácticas de casi todos los miembros de las élites, incluyendo los de los adalides de la "educación popular".

    The process to decipher the genetic code has taken several years and it began with the investigations that he carried out toward half of the XIX century the Czech monk Gregor Mendel who used characteristic contrasting in the plants to study the laws of the inheritance. He made two surprising discoveries. First that many characteristics are inherited in a form of everything or anything: a plant is high or short, and their seeds are flat or rough and second that disappears during a generation when crossing those plants to each other one of the characteristic. When crossing a short plant with a discharge, in the first generation, high plants will only be obtained, but when crossing them again, the characteristic that didn't show during a generation, the short plant will appear again. The article is about the genes and chromosomes, mutations and like the genes work among other topics

  18. More than a Mentor: Leonard Darwin's Contribution to the Assimilation of Mendelism into Eugenics and Darwinism.

    2016-08-01

    This article discusses the contribution to evolutionary theory of Leonard Darwin (1850-1943), the eighth child of Charles Darwin. By analysing the correspondence Leonard Darwin maintained with Ronald Aylmer Fisher in conjunction with an assessment of his books and other written works between the 1910s and 1930s, this article argues for a more prominent role played by him than the previously recognised in the literature as an informal mentor of Fisher. The paper discusses Leonard's efforts to amalgamate Mendelism with both Eugenics and Darwinism in order for the first to base their policies on new scientific developments and to help the second in finding a target for natural selection. Without a formal qualification in biological sciences and as such mistrusted by some "formal" scientists, Leonard Darwin engaged with key themes of Darwinism such as mimicry, the role of mutations on speciation and the process of genetic variability, arriving at important conclusions concerning the usefulness of Mendelian genetics for his father's theory.

    In 1965, Mendel was still celebrated as the undisputed founder of genetics. In the ensuing 50 years, scholars questioned and undermined this traditional interpretation of his experiments with hybrid plants, without, however, managing to replace it: at the sesquicentennial of the presentation of his 'Versuche' (1865), the Moravian friar remains, to a vast majority, the heroic Father of genetics or at least some kind of geneticist. This exceptionally inert myth is nourished by ontological intuitions but can only continue to flourish, thanks to a long-standing conceptual void in the historiography of biology. It is merely a symptom of this more fundamental problem. Copyright © 2015 Elsevier Ltd. All rights reserved.

    A falling apple inspired Isaac Newton’s insight into the law of gravity—or so the story goes. Is it true? Perhaps not. But the more intriguing question is why such stories endure as explanations of how science happens. Newton’s Apple and Other Myths about Science brushes away popular misconceptions to provide a clearer picture of great scientific breakthroughs from ancient times to the present. Among the myths refuted in this volume is the idea that no science was done in the Dark Ages, that alchemy and astrology were purely superstitious pursuits, that fear of public reaction alone led Darwin to delay publishing his theory of evolution, and that Gregor Mendel was far ahead of his time as a pioneer of genetics. Several twentieth-century myths about particle physics, Einstein’s theory of relativity, and more are discredited here as well. In addition, a number of broad generalizations about science go under the microscope of history: the notion that religion impeded science, that scientists typically a...

  6. The role of radiation induced mutations in crop Improvement

    Souframanien, J.

    2017-01-01

    Sudden, heritable changes in the genetic material, DNA, are known as mutations. Selection of naturally occurring mutations in wild, ancestral species helped humans in the domestication and further improvement of today's crop plants. Gregor Mendel in 1865 used several such natural mutants in his experiments with garden pea to formulate the laws of inheritance. The term mutation itself was used for the first time by Hugo de Vries in 1901 in his mutation theory. Plant breeding based on the science of genetics, as practiced over the past 100 years, exploited the available genetic variability in the primary gene pool of crop plants, and sometimes in related species. Primarily, simple selection of desirable offspring and cross breeding were the earlier methods of breeding and this utilized the occurrence of spontaneous mutations. In nature, occurrence of natural variability in the form of spontaneous mutations is extremely low (about 10 -6 ), which can be enhanced several fold (∼10 -3 ) by using ionizing radiations or chemical mutagens

  7. Ultraviolet spectrophotometry of 2A 1822--371: A bulge on the accretion disk

    The X-ray source 2A 1822--371 has been observed with the IUE satellite over an 8 hour period. Long and short wavelength exposures of duration 45 or 60 minutes were alternated in order to resolve the 5.57 hr photometric modulation of the star. The data provide evidence that the shape of the 5.57 hr modulation evolves smoothly with energy between extremes defined by the optical and X-ray curves. The far-UV light curve is more deeply modulated than the X-ray light curve. The combined ultraviolet and the UBV band optical data can be fitted with a single blackbody of temperature 2.7 x 10 4 K, or an optically thick disk model with parameters T/sub asterisk/ = 1.2 x 10 5 K and R/sub out//R/sub in/approx.30. A single power-law model does not adequately represent the continuum. There is evidence of absorption due to the 2200 A interstellar feature whose depth requires a color excess, E(B--V)approx.0.1, with 3 sigma upper and lower bounds of 0.29 and 0.01. Emission lines of C IV 1550 A and N V 1240 A are detected in the UV spectrum. The work of Mason et al. and White et al. suggests that the optical and ultraviolet emission arises in an accretion disk, whereas the X-radiation is emitted from a scattering cloud that envelopes a central compact object. In the present paper, the 5.57 hr optical, X-ray and ultraviolet modulation of 2A 1822--371 is intrepreted as the result of partial occultation of the emitting region by a comparison star and a bulge on the outer accretion disk. X-ray heating of the bulge will probably also contribute to the modulation at optical and ultraviolet wavelengths

    Oligonychus ilicis (McGregor) is among those mite species that can cause damage to coffee plants (Coffea spp.). Species of Phytoseiidae acari are considered the most important and studied predatory mites. The objective of this study was to evaluate the effects of the webbing produced by O. ilicis on its predation by females of the phytoseiids Iphiseiodes zuluagai Denmark and Muma, Euseius citrifolius Denmark and Muma and Amblyseius herbicolus (Chant). Four bioassays were conducted, with three treatments and ten replicates. Each replicate consisted of 25 O. ilicis per experimental unit (a leaf disc of Coffea arabica) according to the tested developmental stage, in independent experiments. To spin the web, 15 adult females were put on each experimental unit for 24h; females were then removed, leaving only the web, and predators and prey to be tested were introduced. Predation was assessed after 24h. In the presence of webbing, the consumption of eggs, larvae and nymphs by I. zuluagai and eggs and larvae by E. citrifolius was lower. For A. herbicolus, egg predation was lower, but larval predation did not vary significantly and predation of nymphs and adults was higher in the presence of webbing. Predators as a whole were more efficient consuming larvae regardless of the presence of webbing. Considering the stages of O. ilicis altogether, webbing reduced the predation potential of I. zuluagai and E. citrifolius, but not of A. herbicolus. (author)

    Near-term brain structure was examined in preterm infants in relation to neurodevelopment. We hypothesized that near-term macrostructural brain abnormalities identified using conventional magnetic resonance imaging (MRI), and white matter (WM) microstructure detected using diffusion tensor imaging (DTI), would correlate with lower cognitive and motor development and slower, less-stable gait at 18-22 mo of age. One hundred and two very-low-birth-weight preterm infants (≤1,500 g birth weight; ≤32 wk gestational age) were recruited prior to routine near-term brain MRI at 36.6 ± 1.8 wk postmenstrual age. Cerebellar and WM macrostructure was assessed on conventional structural MRI. DTI was obtained in 66 out of 102 and WM microstructure was assessed using fractional anisotropy and mean diffusivity (MD) in six subcortical brain regions defined by DiffeoMap neonatal atlas. Neurodevelopment was assessed with Bayley-Scales-of-Infant-Toddler-Development, 3rd-Edition (BSID-III); gait was assessed using an instrumented mat. Neonates with cerebellar abnormalities identified using MRI demonstrated lower mean BSID-III cognitive composite scores (89.0 ± 10.1 vs. 97.8 ± 12.4; P = 0.002) at 18-22 mo. Neonates with higher DTI-derived left posterior limb of internal capsule (PLIC) MD demonstrated lower cognitive and motor composite scores (r = -0.368; P = 0.004; r = -0.354; P = 0.006) at 18-22 mo; neonates with higher genu MD demonstrated slower gait velocity (r = -0.374; P = 0.007). Multivariate linear regression significantly predicted cognitive (adjusted r(2) = 0.247; P = 0.002) and motor score (adjusted r(2) = 0.131; P = 0.017). Near-term cerebellar macrostructure and PLIC and genu microstructure were predictive of early neurodevelopment and gait.

    Full Text Available The citrus red mite, Panonychus citri (McGregor, is a major citrus pest with a worldwide distribution and an extensive record of pesticide resistance. However, the underlying molecular mechanism associated with fenpropathrin resistance in this species have not yet been reported. In this study, synergist triphenyl phosphate (TPP dramatically increased the toxicity of fenpropathrin, suggesting involvement of carboxylesterases (CarEs in the metabolic detoxification of this insecticide. The subsequent spatiotemporal expression pattern analysis of PcE1, PcE7 and PcE9 showed that three CarEs genes were all over-expressed after insecticide exposure and higher transcripts levels were observed in different field resistant strains of P. citri. Heterologous expression combined with 3-(4,5-dimethyl-thiazol-2-yl-2,5-diphenyltetra-zolium bromide (MTT cytotoxicity assay in Spodoptera frugiperda (Sf9 cells revealed that PcE1-, PcE7- or PcE9-expressing cells showed significantly higher cytoprotective capability than parental Sf9 cells against fenpropathrin, demonstrating that PcEs probably detoxify fenpropathrin. Moreover, gene silencing through the method of leaf-mediated dsRNA feeding followed by insecticide bioassay increased the mortalities of fenpropathrin-treated mites by 31% (PcE1, 27% (PcE7 and 22% (PcE9, respectively, after individual PcE gene dsRNA treatment. In conclusion, this study provides evidence that PcE1, PcE7 and PcE9 are functional genes mediated in fenpropathrin resistance in P. citri and enrich molecular understanding of CarEs during the resistance development of the mite.

    Full Text Available The 19th Century pedagogical congresses carried out in Cuba and Central America were led by teachers and officials involved in the educational policy of primary education, and aware of the need to adjust the education’s foundation in order to react to the moment’s reality. This piece analyses the special conditions in Cuba and Central America that cause the reform of the primary education grounds that prevailed in schools during the Colony in the 18th and 19th Centuries. It also describes the protagonists in the educational practice elite that influenced the restruturing of the school system, knowledge and learning techniques, as well as the teachers’ educational or occupational profile. In addition, it outlines the economic circumstances and the political view of the groups of intellectuals trained in a context that inherited the legacy of the colonial conditions of racism and defense of agricultural and industrial work, and defined by abolitionist and pro-independence struggles.  The study was conducted from the UNESCO Memory of the First Central Pedagogical Congress and current research that relate to the Cuban Congress 1884, to identify educational activities and careers of influential intellectuals in shaping Cuban and Central American educational systems at sundown nineteenth century.

    Full Text Available In this paper the authors give an anatomical and histological analysis of the male reproductive system of Pomacea canaliculata (Lamarck, 1822. Anatomically, the testis is better evidentiated than the ovary. In the structure of the testis a great number of very small channels converges to a single one. The male copulatory organs result of transformations that take place in the inner surface on the palial membrane. Histologically, the testis of immature males shows seminiferous ducts with round egg-shaped forms. In their lumens we could notice masses of cells that will originate spermatozoids. The penis has a conjunctive muscular sheath that can be seen in van Gieson's coloured preparations.

    The twenty-fifth anniversary congress of the South African Association of Physicists in Medicine and Biology was held from 18-22 March 1985 in Cape Town. The tremendous growth of nuclear energy and radiation technology in South Africa led to an increasing need for biophysicists, especially health physicists, for the application of radioisotopes and radiation as well as nuclear power, including the uranium industry. Papers delivered on the conference covered subjects like medical physics, radiotherapy, radiopharmaceuticals, radiation protection, the calibration of radiation monitors, radiation detectors, radiation doses and dosimetry

    A novel rickettsial sequence in the citrate synthase gltA gene indicating a novel Rickettsia species has been detected in 7 out of 4524 Ixodes ricinus ticks examined within several surveys performed in the Czech Republic from 2005 to 2009. This new Candidatus Rickettsia sp. sequence has been found in 2 nymphs feeding on wild birds (Luscinia megarhynchos and Erithacus rubecula), in a male tick from vegetation, and 4 ticks feeding on a dog (3 males, 1 female tick). Portions of the ompA, ompB, sca4, and htrA genes were not amplifiable in these samples. A maximum likelihood tree of rickettsiae based on comparisons of partial amino acid sequences of citrate synthase and nucleotide sequences of 16S rDNA genes and phylogenetic analysis revealed a basal position of the novel species in the proximity of R. bellii and R. canadensis. The novel species has been named 'Candidatus Rickettsia mendelii' after the founder of genetics, Gregor Mendel. Copyright © 2016 Elsevier GmbH. All rights reserved.

    2007-03-01

    Charles Bland Radcliffe (1822-1889) was one of the physicians who made major contributions to the literature on epilepsy in the mid-19th century, when the modern understanding of the disorder was beginning to emerge, particularly in England. His experimental work was concerned with the electrical properties of frog muscle and nerve. Early in his career he related his experimental findings to the phenomenon of rigor mortis and concluded that, contrary to the general belief of the time, muscle contraction depended on the cessation of nerve input, and muscle relaxation on its presence. He adhered to this counter-intuitive interpretation throughout his life and, based on it, produced an epileptology that was very different from those of his contemporaries and successors. His interpretations were ultimately without any direct influence on the advance of knowledge. However, his idea that withdrawal of an inhibitory process released previously suppressed muscular contractile powers, when applied to the brain rather than the periphery of the nervous system, permitted Hughlings Jackson to explain certain psychological phenomena that accompany or follow some epileptic events. As well, Radcliffe was one of the chief early advocates for potassium bromide, the first effective anticonvulsant.

He tried to lay down the tale of his life, a tale that was always unsteady. This article connects his work, and especially his Letters from Spain (1822, with the European debate on national characters. To a large extent, this debate was based on an understanding of Europe in which the Mediterranean backward South worked as an opposite mirror for the modern North. Through the work of Blanco White we can analyse how this understanding influenced the way in which identities were designed and constructed in the Europe of the first decades of the nineteenth century.

    Oligonychus ilicis (McGregor) is among those mite species that can cause damage to coffee plants (Coffea spp.). Species of Phytoseiidae acari are considered the most important and studied predatory mites. The objective of this study was to evaluate the effects of the webbing produced by O. ilicis on its predation by females of the phytoseiids Iphiseiodes zuluagai Denmark and Muma, Euseius citrifolius Denmark and Muma and Amblyseius herbicolus (Chant). Four bioassays were conducted, with three treatments and ten replicates. Each replicate consisted of 25 O. ilicis per experimental unit (a leaf disc of Coffea arabica) according to the tested developmental stage, in independent experiments. To spin the web, 15 adult females were put on each experimental unit for 24h; females were then removed, leaving only the web, and predators and prey to be tested were introduced. Predation was assessed after 24h. In the presence of webbing, the consumption of eggs, larvae and nymphs by I. zuluagai and eggs and larvae by E. citrifolius was lower. For A. herbicolus, egg predation was lower, but larval predation did not vary significantly and predation of nymphs and adults was higher in the presence of webbing. Predators as a whole were more efficient consuming larvae regardless of the presence of webbing. Considering the stages of O. ilicis altogether, webbing reduced the predation potential of I. zuluagai and E. citrifolius, but not of A. herbicolus. (author)

Acaricide concentrations were prepared as a two times the field application dose (2T, field application dose (T, and half of the field application dose (T/2 and were then applied on eggs, nymphs and adults of the P. persimilis and N. californicus. The side effects of the acaricidesapplied to the predator mites were determined three, five and seven days afterthe application. While all doses of acequinocyl and etoxazole showed a higher toxic effect on N.californicus eggs, it was found that bifenazate and milbemectin caused similar effects on both predator mite eggs. Furthermore, it was found that the toxic effects of acequinocyl, etoxazole, bifenazate and milbemectin on nymphs and adults of the predator miteswere high seventh day after the application. The results of the study showed that four acaracides frequently used against to pest mites, should be used more carefully in the agricultural areas.

    Dr Milenko Petrović was one of the very distinguished physicians in the history of Sombor city, who significantly contributed to the development of health care in Voivodina. His father Dimitrije was a professor in the High Teacher-training School in Sombor, recognized writer and politician of his epoch. He was born in Sombor in 1884, where he was educated and finished grammar school. For medical studies he moved to Budapest as a boarder of the famous Tekelianum, and graduated in 1908. He started specialisation in surgery, but being a great patriot he voluntarily recruited in the Serbian army to fight in Balkan liberation wars against Turkey. For his excellent work as a war surgeon he obtained many recognitions. After completing specialization in surgery in Debrecin, he returned to his native city Sombor, where he intended to practice as a physician, but because af the outbreak of the first world he was mobilized and sent to the front in Galicia. After the war he again returned to Sombor where he was immediatelly nominated for the main county physician and then begins his fruitful many year's work on the establishment and promotion of the health care in Sombor and broader territory. As the main county phsician he initiated the foundation and construction of the hospital in Sombor, because of high mortality rate among children, and spreading of contagious diseases like tuberculosis and trachoma. The construction of the hospital was completed in 1925 and Dr. Petrović was appointed its first director and this duty he performed for many years till the World War 2 in 1941. Under his management the hospital in Sombor became one of the best quality hospitals in the country and gave a big contribution to the promotion of health of the inhabitants of Voivodina. In spite of his extensive duties in the hospital. Dr. Milenko Petrović was very much engaged in social work, as the president of library "Laza Kosti ć". in the Soko association, Fire brigade, Rotary club, and he

Without appropriate and long-term well organized management action, the population of javan rhino will be in extinction. This research studies about the usage potential of  javan rhino population genetics data in designing  javan rhino conservation program. The application of genetics study in conservation problem is based on the population genetics theory. The population genetics is one of population biology branch which studies about the factors determining genetic composition of population and how they play role in evolution process. The genetic characteristic identification can help to give the characteristic genetic information which has function as genetic marker or gen in javan rhino management. It can also help to do translocation the javan rhino especially for breeding management effort to avoid inbreeding and to improve the heterozygosis. The analyzing result shows that the management of conservation strategy which can make javan rhino population reaches the population viable minimum number is needed urgently. Furthermore, it also shows that translocation and reintroduction to build the second population of  javan rhino is also important to do.    Keywords: javan rhino, population genetics, translocation, second population

    Full Text Available This article is a part of my doctorate research1, which aimed at understanding the foundation and the operation of the journalistic discourse in Brazil and the meaning of nation, freedom and independence during the years 1821 and 1822. This research is theoretically based on the Discourse Analysis (Pêcheux, 1969, 1975; Orlandi, 1996, 1999 producing interpretation moves that will make it possible to understand part of the functioning of an epoch, as well as of a social practice that produces founding principles. We realize that it was not the arrival of the Portuguese Court to Brazil that produced a Brazilian journalistic discourse, but the presence of a Brazilian press. It was from 1821, with the bill that abolished the previous censorship, that there was a displacement from the journalism determined by the Court to another discursivity. This happens in the textuality of O Macaco Brasileiro. As it installs a new discursivity, it materializes a new Brazilian journalist subject position which corresponds to the foundation of the Brazilian journalistic discourse.Este artigo é um recorte da minha pesquisa de doutorado, cujo objetivo foi compreender a fundação e o funcionamento do discurso jornalístico no Brasil e os sentidos de nação, liberdade e independência nos anos de 1821-1822.

    Full Text Available “Przeglad Powszechny” first appeared in 1884, when the Jesuits in Krakow agreed to take over “Przeglad Lwowski” from Fr. Edward Podolski, who had been its editor. At the turn of the 19th and 20th centuries, the editors-in-chief of the “Przeglad” were Marian Ignacy Morawski SJ, Jan Pawelski SJ, Jan Urban SJ and Jan Rostworowski SJ. Thanks to their efforts and extensive prior editorial experience, “Przeglad” stood for a high level of quality, and was one of the most highly valued social and cultural journals devoted to religious, philosophical, ethical, cultural, historical and political issues. The overriding aims set out by the editors of the review were the dissemination of properly Catholic principles of conduct and obedience to the Church. The article will present the social thought of the Jesuits as they appeared in “Przeglad Powszechny” from the time of its inception until the recovery of Poland’s independence.

    The possible discovery of three new gamma-ray pulsars PSR 0656+14, PSR 0950+08, and PSR 1822-09 (Ma, Lu, Yu, and Young, 1993) in data obtained with the COS-B experiment is reinvestigated using a refined technique for pulsar light curve analysis. The results of this study do not confirm the previously claimed gamma-ray pulsar nature of any of these pulsars. Even when using the standard epoch folding technique in conjunction with energy-dependent acceptance cones, we do not detect pulsed gamma-ray emission from these sources. We suspect that insufficient position accuracy is the cause for the discrepancy between our results and those of Ma et al. (1993). We do not rule out that any one of the three candidates, or all of them, is in fact a gamma-ray pulsar, but their spin properties must differ from those derived by Ma et al. (1993). More work is needed to determine the correct high-energy properties of these three sources.

    The morphological characteristics of myoepithelial cells and arrectores pilorum muscles were investigated in caudal, metatarsal and preorbital glands of Hokkaido sika deer (Cervus nippon yesoensis Heude, 1884) using immunohistochemistry for alpha-smooth muscle actin. In the metatarsal, preorbital and general skin glands, myoepithelial cell layers continuously embraced the secretory epithelium, while in the caudal gland, discontinuous myoepithelial cell rows surrounded the apocrine tubules. There was a trend that the widths of the myoepithelial cells of the caudal and preorbital glands appeared to be thinner than those of the metatarsal and general skin glands. In the metatarsal gland, the arrectores pilorum muscles were highly developed and considerably larger than those in other skin glands.

A toxicidade residual dos produtos foi avaliada duas horas e 1; 3; 5; 7; 10; 14 e 21 dias após a aplicação. Em cada arena, foram transferidas dez fêmeas adultas de N. californicus, juntamente com uma quantidade suficiente de Tetranychus urticae, como fonte de alimento. As avaliações de mortalidade foram realizadas 72 horas após a transferência dos ácaros para as arenas. Os agrotóxicos acrinathrin, deltamethrin, dinocap, enxofre, fenpropathrin, óxido de fenbutatin e propargite não causaram mortalidades significativas em adultos de N. californicus. Foram registradas mortalidades de 29,8; 24,0 e 34,1% para ácaros N. californicus expostos a resíduos de duas horas de idade de abamectim, azocyclotin e cyhexatin, respectivamente. Dicofol, pyridaben e chlorfenapyr causaram 100% de mortalidade aos ácaros predadores expostos aos resíduos tóxicos dos acaricidas, com duas horas de idade. Abamectin provocou mortalidade significativa por um período inferior a um dia. Resíduos dos acaricidas azocyclotin, cyhexatin, dicofol, pyridaben e chlorfenapyr provocaram mortalidades significativas por períodos de 1; 1; 10; 10 e 21dias, respectivamente.

    A suite of tetra-nucleotide microsatellite loci were developed for the invasive giant African land snail, Achatina (=Lissachatina) fulica Bowdich, 1822, from Ion Torrent next-generation sequencing data. Ten of the 96 primer sets tested amplified consistently in 30 snails from Miami, Florida, plus 12 individuals representative of their native East Africa, Indian and Pacific Ocean regions. The loci displayed moderate levels of allelic diversity (average 5.6 alleles/locus) and heterozygosity (average 42 %). Levels of genetic diversity were sufficient to produce unique multi-locus genotypes and detect phylogeographic structuring among regional samples. The invasive A. fulica can cause extensive damage to important food crops and natural resources, including native flora and fauna. The loci characterized here will be useful for determining the origins and tracking the spread of invasions, detecting fine-scale spatial structuring and estimating demographic parameters.

    The maintenance of horizontal gaze is an essential function of upright posture and global sagittal spinal alignment. Horizontal gaze is classically measured by the chin-brow vertical angle (CBVA), which is not readily measured on most lateral spine radiographs. To evaluate relations between CBVA and the slope of the line of sight, the slope of McGregor's line (McGS), and Oswestry Disability Index. Patients were identified from a single center database of 531 spine patients who underwent full-body EOS x-rays. Correlations between CBVA, the slope of the line of sight, and McGS were assessed. Using a quadratic regression with Oswestry Disability Index and CBVA, windows of low disability were identified. Comparison of sagittal spinopelvic parameters was carried out between patients with "ascending gaze" and "neutral position." Three hundred three patients were included (74% female, mean age 54.8 years, body mass index 26.6 ± 6.0 kg/m). CBVA strongly correlated with the slope of the line of sight (r = 0.996) and McGS (r = 0.862). Regression studies between Oswestry Disability Index and CBVA yielded a range of values corresponding to low disability (-4.7 degrees to 17.7 degrees). Similarly, a low disability range for the slope of the line of sight (-5.1 degrees to 18.5 degrees) and McGS (-5.7 degrees to 14.3 degrees) was computed. Patients with "ascending gaze" had a worse spinopelvic alignment than "neutral position" patients. The slope of the line of sight and McGS correlated strongly with CBVA and can be used as surrogate measures. The range of values for these measures corresponding to low disability was identified. These values can be used as a general guideline to assess alignment for diagnostic purposes. Cervical compensatory mechanism may modify the natural head position in sagittally misaligned patients.

    Full Text Available In this work we present a revision of the genus Ommatoiulus Latzel, 1884 in Portugal. Based on recently collected material and older museum samples, including type specimens, we describe six new species to science, viz. Ommatoiulus alacygni sp. nov., O. camurus sp. nov., O. denticulatus sp. nov., O. litoralis sp. nov., O. staglae sp. nov. and O. stellaris sp. nov. The species O. alacygni sp. nov., O. denticulatus sp. nov. and O. staglae sp. nov. described from the Algarve are outstanding by their extremely reduced mesomerital process. The species O. porathi (Verhoeff, 1893 and O. andalusius (Attems, 1927 are recorded and redescribed for the first time after their original description. The finding of O. andalusius – originally described from Andalusia in Spain – constitutes a new record for Portugal together with two species, viz. O. fuentei (Brolemann, 1920 and O. martensi Mauriès, 1969. The taxonomic status of several species is revised. Thus Archiulus (Schistocoxitus cingulatus Attems, 1927 is here considered as a junior synonym of Ommatoiulus lusitanus (Verhoeff, 1895 while Schizophyllum cervinum Verhoeff, 1910 is synonymized with Ommatoiulus moreleti (Lucas, 1860. An identification key to all hitherto known Portuguese species of Ommatoiulus is presented as well as a distribution map illustrating the various species occurrences in the country.

    Full Text Available Rethinking Darwin? About Ex‐aptations and Neotenies. Concerning Mickey Mouse, Goofy and likeable mexican Salamanders The theory of evolution by natural selection of Charles Darwin, whose first general exposure dates back to 1859, with the publication of the Origin of Species, is still a matter of intense debate among natural sciences’ scholars and philosophers. After the merger of Darwinian evolutionary research program with the theory of heredity of Gregor Mendel, the mathematical form of population genetics and the analysis of paleontological data (Modern Synthesis and the the important contributions of post-Darwinian authors such as S.J. Gould and N. Eldredge we are entering a new era of great discoveries and news. On the one hand, new data from genetics and paleoanthropology, on the other hand the impetuous development of some fields of applied science such as nanobiotechnology, genetic engineering and synthetic biology put us into the need and the urgency to underline, once again, the relevance and the extraordinary heuristic power of Darwinian research program, an even greater urgency since some authors have announced that we would be at a time to access a post-Darwinian and post-evolutionary era in which man as we actually know it is about to disappear.

    Full Text Available The oviposition preference of the red mite Oligonychus yothersi McGregor was evaluated under laboratory in 52 Paraguay tea progenies and one control collected in a local farm. The experiments were conducted on Paraguay tea leaf discs infested with one adult female mite/disc, incubated in a climate chamber (25±1ºC, 14h photophase for five days. Evaluations were performed daily, by counting the number of eggs laid in the period, the number of female escapes in the first 48 hours, as well as the number of eggs laid before the escaping. It was verified that discrimination by the mite occurred on two groups of progenies, in relation to the number of eggs: one group was different from the control (53.8% of the progenies and the other was identical to it (46.2% of the progenies. In the first group, 60.7% of progenies were less oviposited while a higher number of eggs/female than the control was verified in 39.3% of them. In 57.7% of progenies there was escape of some mites (10 to 40%, and in 10 of these progenies no eggs were laid. The data provide evidences that in some of the progenies evaluated there is resistance by non-preference to oviposition of the Paraguay tea red mite.A preferência para oviposição do ácaro-vermelho, Oligonychus yothersi McGregor, foi avaliada em condições de laboratório em 52 progênies de erva-mate e uma testemunha coletada em uma propriedade da região.

    Full Text Available African catfish (Clarias gariepinus Burchell, 1822 has become a great important species in Indonesian aquaculture. Several strains of the African catfish have been introduced to Indonesia for aquaculture purposes, initiated by Dumbo strain from Taiwan in 1985, followed by Paiton strain from Thailand in 1998, then Egypt strain from Egypt in 2007, Masamo strain from Thailand in 2010 and later Kenya strain from Kenya in 2011. Since its introductions, there were no reports yet on their characterization studies. The present study was conducted to morphologically characterize the strains of African catfish introduced to Indonesia, i.e. Dumbo, Paiton, Egypt, Masamo, and Kenya strains. Morphometric and meristic data obtained were analyzed using Principal Component Analysis. Results of the morphometric characterization in the present study revealed that Dumbo, Paiton, Masamo, and Kenya strains were indistinguishable, while morphometric characteristic of Egypt strain was more or less different from those of the other strains. On the other hand, results of the meristic characterization suggested that meristic characteristics of all strains of the introduced African catfish were not different from each other. Therefore, to keep the genetic purity of those introduced strains, they should be properly maintained in isolated places.

    Salvator Karabaić was born in Krk in 1884. In 1904, he finished a grammar school in Susak, and in 1910 graduated from the Vienna Medical School. From 1910 to 1919, he worked in Pula/Pola and Kovin. From 1919 to 1929 he worked at the Institute for Mental illnesses Stenjevec (today the Psychiatric Hospital Vrapce) where in 1921 he became the head physician (orig. primarius) at the age of 37 years only. Between 1929 and 1945, he worked in Sarajevo as a Head of the State Hospital's Neuropsychiatry Department. In 1948 he was appointed the director of the Hospital for Mental Illnesses in Sarajevo. The hospital was in fact a remodelled rope factory with a favourable position near a homestead. He managed this institution until 1956. He died on 24 September 1956 at a hospital surgery ward in Sarajevo. Judging by Dr Karabaić's ability to take care of 200 psychiatric patients alone, he was an outstanding figure with enormous experience. A lot of it he earned during the Vrapce hospital period between 1919 and 1929. He had the opportunity to work with the outstanding figures of Croatian psychiatry such as Dr Ivo Zirovcić, Dr Laza Stanojević, Dr Ivan Barbot, and Dr Aleksej KuljZenko The author suggests that a more systematic research is needed to understand the work and the life of Dr Salvator Karabaić, who was a talented and hardworking psychiatrist/ neuropsychiatrist with outstanding managing capabilities, and a person who above all cared for his patients.

    Full Text Available The predatory mite, Neoseiulus californicus(McGregor, 1954 (Acari: Phytoseiidae is one of the principal natural enemies of tetranychid mites in several countries, promoting efficient control of those mites in several food and ornamental crops. Pest attacks such as that of the spider mite, Tetranychus urticaeKoch, 1836 (Acari: Tetranychidae, is one of the problems faced by farmers, especially in the greenhouse, due to the difficulty of its control with the use of chemicals because of the development of fast resistance making it hard to control it. The objective of this work was to study the life history of the predatory mite N. californicus as a contribution to its mass laboratory rearing, having castor bean plant [Ricinus communis L. (Euphorbiaceae] pollen as food, for its subsequent use as a natural enemy of T. urticae on a cultivation of greenhouse rosebushes. The studies were carried out in the laboratory, at 25 ± 2°C of temperature, 70 ± 10% RH and a 14 hour photophase. The biological aspects and the fertility life table were appraised. Longevity of 32.9 days was verified for adult females and 40.4 days for males. The intrinsic rate of increase (rm was 0.2 and the mean generation time (T was 17.2 days. The population doubled every 4.1 days. The results obtained were similar to those in which the predatory mite N. californicus fed on T. urticae.

    Cervical carcinoma remains the second most common malignancy with a high mortality rate among women worldwide. TAD-1822-7-F2 (F2) and TAD-1822-7-F5 (F5) are novel compounds synthesized on the chemical structure of taspine derivatives, and show an effective suppression for HeLa cells. Our study aims to confirm the potential targets of F2 and F5, and investigate the underlying mechanism of the inhibitory effect on HeLa cells. In this study, Real Time Cell Analysis and crystal violet staining assay were conducted to investigate the effect of F2 and F5 on HeLa cells proliferation. And the analytical methods of surface plasmon resonance and quartz crystal microbalance were established and employed to study the interaction between F2 and F5 and potential target protein JAK2, suggesting that both compounds have strong interaction with the JAK2 protein. Western blot analysis, immunofluorescence staining study and PCR was conducted to investigate the molecules of JAK/Stat signaling pathway. Interestingly, F2 and F5 showed diverse regulation for signaling molecules because of their different chemical structure. F2 increased the expression of JAK2 and downregulated the level of P-JAK1 and P-JAK2, and decreased P-Stat3 (Ser727). While F5 could increase the expression of JAK2 and naturally decrease the phosphorylation of JAK1 and Tyk2, and decreased the expression of P-Stat6. Moreover, F2 and F5 showed the same downregulation on the P-Stat3 (Tyr705). Therefore, F2 and F5 could target the JAK2 protein and prevent the phosphorylation of JAKs to suppress the phosphorylation of the downstream effector Stats, which suggested that F2 and F5 have great potential to be the inhibitors of the JAK/Stat signaling pathway.

    Full Text Available The egg and larval development of reciprocal crosses of Pangasianodon hypophthalmus (Sauvage, 1878 and Clarias gariepinus (Burchell, 1822 were studied under laboratory conditions. Crosses between ♀C. gariepinus × ♂P. hypophthalmus (Clariothalmus and ♀P. hypophthalmus × ♂C. gariepinus (Pangapinus had embryonic stages similar to those of the pure sib, however, unequal cell cleavages were notable in the early development of both crosses, hence, leading to different forms of deformities. The critical stage where highest mortality occurred during the embryogenesis was the somite (21.68% and hatching (48.1% stages (respectively for the Clariothalmus and Pangapinus. However, both crosses produced viable larvae (60.21 vs 13.20% hatchability respectively, which survived (30.3 vs 2.1% respectively until the end of the study (2 weeks. The external morphological features of the larvae were completely formed by the 14th day after hatching. The body forms of the crosses at this time were either phenotypic intermediary of the parent species (92% of Clariothalmus or indistinguishable from the female parent (all Pangapinus and 8% of the Clariothalmus. This study thus laid the groundwork for further comparative studies on hybrid performance and characterization.

    Full Text Available Antonio Muñoz (1884-1960 is usually remembered for his successful career in the administration and conservation of the monumental heritage in Rome during the Fascist era. His brief yet relevant activity as a Byzantinist is often underestimated in the secondary literature, despite the fact that, before the 1914-18 war, he was unanimously considered as the most promising Italian specialist in Byzantine art. From 1903 onwards, after completing his studies with Adolfo Venturi, Muñoz developed an interest in Byzantine illumination, which became his primary area of expertise. At this early stage, his most important work was without doubt the new edition of the Rossano Gospels (1907, which was internationally praised as a significant step forward in the history of Byzantine illumination. With the support of previously unpublished or little-known documents, this article aims to provide a new critical analysis of Muñoz’s research on Byzantine illumination, as well as a more balanced evaluation of its impact on the scholarly community at the turn of the twentieth century.

    Based on light and scanning electron microscopy, two new species of philometrid nematodes, Spirophilometra endangae sp. nov. and Philometra epinepheli sp. nov. (Nematoda: Dracunculoidea: Philometridae) are described from Epinephelus coioides (Hamilton, 1822) (Perciformes: Serranidae) from the South Bali Sea, Indonesia. Spirophilometra endangae sp. nov. was isolated from the fins of E. coioides. The new species can be distinguished from the most closely related S. eichleri Parukhin, 1971 by a larger total body length and the site of infection in the host. The new species differs from S. centropomi (Caballero, 1974) also in the larger body size of the gravid females and the site of infection in the host. S. en-dangae sp. nov. differs from S. pacifica (Moravec, Santana-Pineros, Gonzales-Solis & Torres-Huerta, 2007) in the struc-ture and arrangement of the spines on the middle part of the body, the infection site of the worm, the type host and the zoogeographical host distribution. Philometra epinepheli sp. nov. differs from all other Philometra spp. congeners so far recorded from Ephinepelus groupers in the total body length and the site of infection. This is the first opercula-infecting species of Philometra described from the fish family Serranidae.

  14. The Development of Genetics in the Light of Thomas Kuhn's Theory of Scientific Revolutions.

    The concept of a paradigm is in the key position in Thomas Kuhn's theory of scientific revolutions. A paradigm is the framework within which the results, concepts, hypotheses and theories of scientific research work are understood. According to Kuhn, a paradigm guides the working and efforts of scientists during the time period which he calls the period of normal science. Before long, however, normal science leads to unexplained matters, a situation that then leads the development of the scientific discipline in question to a paradigm shift--a scientific revolution. When a new theory is born, it has either gradually emerged as an extension of the past theory, or the old theory has become a borderline case in the new theory. In the former case, one can speak of a paradigm extension. According to the present author, the development of modern genetics has, until very recent years, been guided by a single paradigm, the Mendelian paradigm which Gregor Mendel launched 150 years ago, and under the guidance of this paradigm the development of genetics has proceeded in a normal fashion in the spirit of logical positivism. Modern discoveries in genetics have, however, created a situation which seems to be leading toward a paradigm shift. The most significant of these discoveries are the findings of adaptive mutations, the phenomenon of transgenerational epigenetic inheritance, and, above all, the present deeply critical state of the concept of the gene.

  16. Global impact of induced mutation in plant breeding

    Sudden, heritable changes in the genetic material, DNA, are known as mutations. Selection of naturally occurring mutations in wild, ancestral species helped humans in the domestication and further improvement of today's crop plants. Although Charles Darwin was unaware in 1859 of variation and mutations in living organisms, his theory of evolution by natural selection assumed variability. Much later, it was established that mutations are the source of biodiversity, and the driving force for evolution. Gregor Mendel in 1865 also used several mutants in his experiments with garden pea to formulate the laws of inheritance. The term mutation itself was used for the first time by Hugo de Vries in 1901 in his mutation theory. Plant breeding based on the science of genetics, as practiced over the past 100 years, exploited the available genetic variability in the primary gene pool of crop plants, and sometimes in related species. This approach enlarged the yield potential of crops several fold. It also a) improved the stability of yield by incorporating resistance to various biotic and abiotic stresses; b) improved quality of the produce; and c) altered the adaptability of crop species, providing opportunities to grow new crops for food security outside their traditional range. Genetically improved seed (or other planting material) is the most significant input for developing sustainable cropping systems for food security and economic growth. Half of the increased productivity of today's crop plants comes from genetic improvements. The other half is contributed by inputs and management practices

  17. FORSTERIAN MODEL OF CHARACTERIZATION AND NON-HUMAN CHARACTERS IN NARRATIVE FICTION: IRIS MURDOCH’S MISTER MARS AND FRANZ KAFKA’S GREGOR SAMSA

    Barış METE

    2017-06-01

    Full Text Available In Aspects of the Novel, Edward Morgan Forster introduces the critical concepts of flat and round to describe the nature of different types of fictional characters. According to Forster’s theoretical categorization, flat characters are constructed and exist in their fictional realm around a single feature or quality. As this is the key criterion, Forster argues that flat characters can easily be recognized and remembered by the reader. Flat characters remain mostly the same through circumstances. In other words, flat characters never surprise the reader. Contrary to the nature of flat characters, round characters operate in an opposite direction to their counterparts. Round characters never remain the same throughout events, and it is not easy to recognize them since they do not exist under the dominance of a single trait. In addition to these, round characters are those who surprise the reader. Although Forster’s categorisation of fictional characters has functioned well in most of the cases, some characters are not easily analysed under this formula. Franz Kafka’s Gregor Samsa, for example, seems neither a round nor a flat character. Throughout his story, he remains the same. At the same time, he surprises the reader, which is not expected from him since he is mostly the same character in the text. Samsa’s turning into an insect further complicates the definition of his roundness or flatness. Another example is Iris Murdoch’s Mister Mars. Mister Mars is an animal. But at the same time he is a movie star, a celebrity. He has a pivotal role for the protagonist of the text. Therefore, the aim of this study is first to introduce the theoretical background of the nature of fictional characters and then to display some difficulties present particularly in Forster’s classification through the characterisation of two non-human examples.

    Full Text Available Este estudo é parte de um projeto que tem como objetivo traçar um panorama histórico das redes discursivas que caracterizam o que a sociedade considera como desviante em um determinado momento, assim como apresentar as mudanças paradigmáticas que ocorrem no próprio diagnóstico do que é patológico nos modos de ser criança e adolescente ao longo do tempo. O referencial teórico e metodológico fundamenta-se na perspectiva genealógica proposta por Michel Foucault, assim como em suas análises sobre os anormais e o poder psiquiátrico. No presente trabalho apresentaremos a análise do período de 1884 a 1937. Constata-se que as redes discursivas sobre as patologias nos territórios da infância e da adolescência permitem identificar algumas descontinuidades e continuidades: descontinuidade do ponto de vista dos diagnósticos encontrados, mas continuidade no que se refere às estratégias de exclusão social

    Full Text Available Livestock grazing had been believed to affect on the existence of wildlife, including the timor deer (Rusa timorensis Blainville 1822 through competition. This study aimed to determine whether the free-roaming horse grazing owned by local communities in Torong Padang Cape, East Nusa Tenggara become a competitor for timor deer. Field observations and interviews with horse owners were carried out to determine the distribution of horse in timor deer habitat. Food preference of both horse and timor deer were collected using species identification from feces and compared with 1 x 1 m2 plots at feeding areas of both animals during the dry and rainy seasons in 2014 and 2015. There is no clear indication of competition between timor deer and free-roaming horses in the Torong Padang Cape area.The deer and horse avoided overlapping spatially in their distribution in the Cape. The free-roaming horse mainly occupied hilly savanna, whereas timor deer preferred to occupy savanna with lebbek tree (Albizia lebbeck (L. Benth and valleys with tropical dry forest vegetation.

    Transformation, which alters the genetic makeup of an individual, is a concept that intrigues the human imagination. In Streptococcus pneumoniae such transformation was first demonstrated. Perhaps our fascination with genetics derived from our ancestors observing their own progeny, with its retention and assortment of parental traits, but such interest must have been accelerated after the dawn of agriculture. It was in pea plants that Gregor Mendel in the late 1800s examined inherited traits and found them to be determined by physical elements, or genes, passed from parents to progeny. In our day, the material basis of these genetic determinants was revealed to be DNA by the lowly bacteria, in particular, the pneumococcus. For this species, transformation by free DNA is a sexual process that enables cells to sport new combinations of genes and traits. Genetic transformation of the type found in S. pneumoniae occurs naturally in many species of bacteria (70), but, initially only a few other transformable species were found, namely, Haemophilus influenzae, Neisseria meningitides, Neisseria gonorrheae, and Bacillus subtilis (96). Natural transformation, which requires a set of genes evolved for the purpose, contrasts with artificial transformation, which is accomplished by shocking cells either electrically, as in electroporation, or by ionic and temperature shifts. Although such artificial treatments can introduce very small amounts of DNA into virtually any type of cell, the amounts introduced by natural transformation are a million-fold greater, and S. pneumoniae can take up as much as 10% of its cellular DNA content (40).

    Full Text Available Objective: To investigate biometrics of the Rhinomugil corsula (Hamilton, 1822 (R. corsula, including length-weight relationships (LWRs, condition factors (Allometric, KA; Fulton’s, KF; Relative, KR; Relative weight, WR, and sex ratio and length-frequency distributions in the Ganges (Padma River, Northwestern Bangladesh. Methods: Monthly sampling was conducted using traditional fishing gears during June to August 2012. Total length was measured to the nearest 0.01 cm using digital slide calipers, and total body weight was measured using an electronic balance with 0.01 g accuracy. The LWR was calculated using the expression: W= a×Lb , where the W is the body weight , L is the total length , a and b are the parameters of the regression. Results: A total of 350 specimens ranging from 8.59-15.71 cm in total length and 9.57-32.59 g in body weight were analyzed during this study. The overall sex ratio was not significantly different from the expected value of 1:1 (χ2 =2.57, P>0.05, but there was significant difference in the length-frequency distributions between the sexes (P=0.03. The allometric coefficient b for the LWR indicated negative allometric growth (b≈3.00 in males, female and combined sexes. Results further indicated that KF was not significantly different between the sexes (P=0.57. However, the mean WR of R. corsula showed significant differences from 100 for males (P=0.03 and females (P<0.001 in this study, indicating the imbalance habitat with food availability relative to the presence of predators. Conclusions: This study reported the first description of biometric relationships for R. corsula, which would be useful for the sustainable conservation of this rear fishery in Bangladesh and also neighboring countries.

    This topical issue of Astronomische Nachrichten/Astronomical Notes is a collection of reference articles covering the GREGOR solar telescope, its science capabilities, its subsystems, and its dedicated suite of instruments for high-resolution observations of the Sun. Because ground-based telescopes have life spans of several decades, it is only natural that they continuously reinvent themselves. Literally, the GREGOR telescope builds on the foundations of the venerable Gregory-Coudé Telescope (GCT) at Observatorio del Teide, Tenerife, Spain. Acknowledging the fact that new discoveries in observational solar physics are driven by larger apertures to collect more photons and to scrutinize the Sun in finer detail, the GCT was decommissioned and the building was made available to the GREGOR project.

    Full Text Available Abstract Background There is now convincing evidence that in industrialized countries therapeutic hypothermia for perinatal asphyxial encephalopathy increases survival with normal neurological function. However, the greatest burden of perinatal asphyxia falls in low and mid-resource settings where it is unclear whether therapeutic hypothermia is safe and effective. Aims Under the UCL Uganda Women's Health Initiative, a pilot randomized controlled trial in infants with perinatal asphyxia was set up in the special care baby unit in Mulago Hospital, a large public hospital with ~20,000 births in Kampala, Uganda to determine: (i The feasibility of achieving consent, neurological assessment, randomization and whole body cooling to a core temperature 33-34°C using water bottles (ii The temperature profile of encephalopathic infants with standard care (iii The pattern, severity and evolution of brain tissue injury as seen on cranial ultrasound and relation with outcome (iv The feasibility of neurodevelopmental follow-up at 18-22 months of age Methods/Design Ethical approval was obtained from Makerere University and Mulago Hospital. All infants were in-born. Parental consent for entry into the trial was obtained. Thirty-six infants were randomized either to standard care plus cooling (target rectal temperature of 33-34°C for 72 hrs, started within 3 h of birth or standard care alone. All other aspects of management were the same. Cooling was performed using water bottles filled with tepid tap water (25°C. Rectal, axillary, ambient and surface water bottle temperatures were monitored continuously for the first 80 h. Encephalopathy scoring was performed on days 1-4, a structured, scorable neurological examination and head circumference were performed on days 7 and 17. Cranial ultrasound was performed on days 1, 3 and 7 and scored. Griffiths developmental quotient, head circumference, neurological examination and assessment of gross motor function were

  10. Detailed anatomy of the braincase of Macelognathus vagans Marsh, 1884 (Archosauria, Crocodylomorpha using high resolution tomography and new insights on basal crocodylomorph phylogeny

    Full Text Available Background Macelognathus vagans Marsh, 1884 from the Late Jurassic Morrison Fm. of Wyoming was originally described as a dinosaur by Marsh and in 1971 Ostrom suggested crocodilian affinities. In 2005, Göhlich and collaborators identified new material of this species from Colorado as a basal crocodylomorph. However, a partial skull found in association with mandibular and postcranial remains was not described. Methods Due to the small size and delicate structures within the braincase, micro CT studies were performed on this specimen. The new anatomical information was incorporated in a phylogenetic dataset, expanding both character and taxon sampling. Results This new material reinforces the non-crocodyliform crocodylomorph affinities of Macelognathusas it bears a large otic aperture, unfused frontals and lacks ornamentation on the dorsal cranial bones. The internal structures also support these affinities as this specimen bears traits (i.e., heavily pneumatized and expanded basisphenoid; the presence of additional pneumatic features on the braincase; and the otoccipital-quadrate contact not present in most basal crocodylomorphs. Furthermore, the presence of a wide supraoccipital and a cranioquadrate passage are traits shared with Almadasuchus from the early Late Jurassic of Argentina. Macelognathus was recovered as one of the closest relatives of crocodyliforms, forming a clade (Hallopodidae with two other Late Jurassic taxa (Almadasuchus and Hallopus. Discussion The clade formed by Almadasuchus + Hallopus + Macelognathus, the Hallopodidae, is characterized by a higher degree of suturing of the braincase, posteriorly closed otic aperture (paralleled in mesoeucrocodylians and cursorial adaptations. Also, the phylogenetic position of this lineage of derived crocodylomorphs as the sister group of Crocodyliformes implies a large amount of unsampled record (ghost lineage, at least 50 million years.

    Full Text Available Genetic variation is a key component for improving a stock through selective breeding programs. Randomly amplified polymorphic DNA (RAPD markers were used to assess genetic variation in three wild population of the catla carp (Catla catla Hamilton 1822 in the Halda, Jamuna and Padma rivers and one hatchery population in Bangladesh. Five decamer random primers were used to amplify RAPD markers from 30 fish from each population. Thirty of the 55 scorable bands were polymorphic, indicating some degree of genetic variation in all the populations. The proportion of polymorphic loci and gene diversity values reflected a relatively higher level of genetic variation in the Halda population. Sixteen of the 30 polymorphic loci showed a significant (p < 0.05, p < 0.01, p < 0.001 departure from homogeneity and the F ST values in the different populations indicated some degree of genetic differentiation in the population pairs. Estimated genetic distances between populations were directly correlated with geographical distances. The unweighted pair group method with averages (UPGMA dendrogram showed two clusters, the Halda population forming one cluster and the other populations the second cluster. Genetic variation of C. catla is a useful trait for developing a good management strategy for maintaining genetic quality of the species.

Ácaros da família Phytoseiidae, de várias espécies, são eficientes predadores associados aos ácaros-praga. Conduziu-se este trabalho com o objetivo de estudar o controle dos ácaros-praga com spirodiclofen e azocyclotin, e o impacto sobre fitoseídeos. Em laboratório foram estudados os efeitos ovicida, tópico, residual, tópico mais residual e a seletividade fisiológica aos fitoseídeos; em casa-de-vegetação foi avaliada a persistência no controle às duas espécies de ácaros-praga; e em campo foi avaliada a eficiência apenas no controle de B. phoenicis. Os bioensaios foram realizados em arenas de folhas destacadas. O efeito ovicida foi avaliado em ovos no início e final de incubação. Os efeitos residual, tópico e tópico mais residual foram avaliados pela mortalidade de larvas, ninfas e adultos aos oito dias, e a persistência até 30 dias após a aplicação. A seletividade aos fitoseídeos foi avaliada, pelo efeito na mortalidade e reprodução de fêmeas adultas, em teste residual em superfície de vidro. Spirodiclofen e azocyclotin (SC mostraram eficiente ação ovicida, principalmente para ovos de B. phoenicis no início de incubação. Para ovos de O. ilicis, somente o spirodiclofen apresentou efeito ovicida. Em geral, os efeitos tópico e residual associados melhoraram a eficiência dos produtos no controle das fases pós-embrionárias de ambas as espécies. O spirodiclofen apresentou seletividade aos ácaros predadores, já o azocyclotin foi nocivo. Em campo, ambos os acaricidas mostram-se altamente eficientes na redução de todas as fases pós-embrionárias do ácaro B. phoenicis, principalmente nas folhas.The mite Brevipalpus

    Difficulties with executive function have been found in preterm children, resulting in difficulties with learning and school performance. This study evaluated the relationship of early working memory as measured by object permanence items to the cognitive and language scores on the Bayley Scales-III in a cohort of children born extremely preterm. Logistic regression models were conducted to compare object permanence scores derived from the Bayley Scales-III by race/ethnicity and maternal education, controlling for medical covariates. Extremely preterm toddlers (526), who were part of a Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network's multi-center study, were evaluated at 18-22 months corrected age. Object permanence scores derived from the Bayley Developmental Scales were compared by race/ethnicity and maternal education, controlling for medical covariates. There were no significant differences in object permanence mastery and scores among the treatment groups after controlling for medical and social variables, including maternal education and race/ethnicity. Males and children with intraventricular hemorrhage, retinopathy of prematurity, and bronchopulmonary dysplasia were less likely to demonstrate object permanence mastery and had lower object permanence scores. Children who attained object permanence mastery had significantly higher Bayley Scales-III cognitive and language scores after controlling for medical and socio-economic factors. Our measure of object permanence is free of influence from race, ethnic and socio-economic factors. Adding this simple task to current clinical practice could help detect early executive function difficulties in young children. Published by Elsevier Ireland Ltd.

    The population structure and genetic diversity of Rohu (Labeo rohita Hamilton, 1822) was studied by analysis of the partial sequences of mitochondrial DNA cytochrome b region. We examined 133 samples collected from six locations in three geographically isolated rivers of India. Analysis of 11 haplotypes showed low haplotype diversity (0.00150), nucleotide diversity (π) (0.02884) and low heterogeneity value (0.00374). Analysis of molecular variance (AMOVA) revealed the genetic diversity of L. rohita within population is very high than between the populations. The Fst scores (-0.07479 to 0.07022) were the indication of low genetic structure of L. rohita populations of three rivers of India. Conspicuously, Farakka-Bharuch population pair Fst score of 0.0000, although the sampling sites are from different rivers. The phylogenetic reconstruction of unique haplotypes revealed sharing of a single central haplotype (Hap_1) by all the six populations with a point mutations ranging from 1-25 nucleotides.

    This work aimed to assessing Strongyluris sp. cysts distribution pattern in the several inner organs from pallial system of Achatina fulica Bowdich, 1822. Also we verified if there is a relationship between the mollusk size and the number of specimens from parasites collected from two touristic villages in Ilha Grande (Angra dos Reis, Rio de Janeiro state): Vila Dois Rios (VDR) and Vila do Abraão (ABR). The samples were obtained through a field work conducted bimonthly during 2007, 2008, 2010, and 2011, at both locations. Height and width were measured from shells collected, and the all specimens were classified in different classes: class 1 - biomass and a larger area of the pallial system, allowing an efficient parasite colonization. Other possible explanation could be the long exposure of the molluscs of class 3 to the parasites, which allowed a longer time to the larvae to allocate themselves.

    Full Text Available Este estudio aborda el nacimiento y desarrollo del asociacionismo gimnástico-deportivo en España en el siglo xix desde 1822 año en el que aparecieron las primeras asociaciones deportivas hasta 1900. Este proceso contribuye al ordenamiento institucional del deporte, a su difusión y a su legitimación social. El asociacionismo deportivo se inició de forma titubeante pero despegó a partir de 1875. La introducción del deporte coincidió con la Restauración borbónica y el fervor de los reyes y la aristocracia por el modelo cultural inglés y el sport, y fue sostenida por el Regeneracionismo y la Institución Libre de Enseñanza. Para construir la lista de entidades que conforman el deporte institucionalizado, se han seguido tres procesos, que beben de fuentes primarias y secundarias. En primer lugar se ha realizado una exhaustiva revisión documental de los trabajos anteriores de dos de los autores. A continuación, se han efectuado búsquedas sistematizadas en las principales plataformas documentales digitalizadas de España. Finalmente, se han contrastado los datos resultantes con los últimos trabajos historiográficos del período. Este proceso metodológico de tres partes produjo una lista de 363 entidades deportivas ubicadas en las zonas más acomodadas e industrializadas. El ciclismo fue el deporte que atrajo mayor número de asociaciones. Los resultados de la investigación muestran la vigorosidad del proceso de institucionalización del deporte en España en el siglo xix y su arraigo inicial entre las capas aristocráticas y burguesas.

    Historically, strategies to reduce acute rejection and improve graft survival in kidney transplant recipients included blood transfusions (BTs) before transplantation. While advents in recipient immunosuppression strategies have replaced this practice, the impact of BTs in the organ donor on recipient graft outcomes has not been evaluated. We hypothesize that BTs in organ donors after neurologic determination of death (DNDDs) translate into improved recipient renal graft outcomes, as measured by a decrease in delayed graft function (DGF). Donor demographics, critical care end points, the use of BTs, and graft outcome data were prospectively collected on DNDDs from March 2012 to October 2013 in the United Network for Organ Sharing Region 5 Donor Management Database. Propensity analysis determined each DNDD's probability of receiving packed red blood cells based on demographic and critical care data as well as provider bias. The primary outcome measure was the rate of DGF (dialysis in the first week after transplantation) in different donor BT groups as follows: no BT, any BT, 1 to 5, 6 to 10, or greater than 10 packed red blood cell units. Regression models determined the relationship between donor BTs and recipient DGF after accounting for known predictors of DGF as well as the propensity to receive a BT. Data were complete for 1,884 renal grafts from 1,006 DNDDs; 52% received any BT, 32% received 1 to 5 U, 11% received 6 to 10, and 9% received greater than 10 U of blood. Grafts from transfused donors had a lower rate of DGF compared with those of the nontransfused donors (26% vs. 34%, p donors with any BT had a lower odds of DGF (odds ratio, 0.76; p = 0.030), and this effect was greatest in those with greater than 10 U transfused. Any BT in a DNDD was associated with a 23% decrease in the odds of recipients developing DGF, and this effect was more pronounced as the number of BTs increased. Therapeutic study, level III; epidemiologic/prognostic study, level II.

    Full Text Available At the same time as Melchor López was carrying out his teaching duties within the music chapel of the cathedral of Santiago (1783-1822, the renovation of his orchestra was undertaken to the point of accomplishing a stable symphony orchestra of the classical sort which had long been firmly established in Central Europe. This greatly influenced the maestro’s music, having studied in Madrid and admirer of F.J. Haydn’s music, where the precise orchestral accompaniment for solo voices and for choirs became the central part of his works and made possible the renovation of the instrumental repertoire which was being used in the liturgy (Masses, Vespers and on other occasions for paraliturgy functions such as the siestas celebrated during the octave of Corpus. Within this renovation, the reception of Haydn’s influence was especially important: his symphonies arrived at the cathedral in the 1790s and are perhaps the most representative element of this renovation which the aforementioned repertoire underwent.De manera paralela al desarrollo del magisterio de capilla ejercido por Melchor López en la catedral de Santiago de Compostela (1783-1822, se produjo la renovación de su orquesta hasta alcanzar de un modo estable los patrones del tipo básico de orquesta sinfónica clásica surgido con fuerza en Europa central años antes. Este hecho influyó en la música del maestro, formado en Madrid y admirador de la música de F. J. Haydn, donde el acompañamiento orquestal preciosista a las voces solistas y al coro, se convirtió en protagonista de la misma, posibilitando además la renovación del repertorio instrumental que se interpretaba en las funciones litúrgicas (Misas, Vísperas y en otros momentos paralelos a los litúrigicos como eran las siestas que se celebraban durante el octavario del Corpus.

  8. Women as Mendelians and Geneticists

    2015-01-01

    After the rediscovery of Mendel's laws of heredity in 1900, the biologists who began studying heredity, variation, and evolution using the new Mendelian methodology—performing controlled hybrid crosses and statistically analyzing progeny to note the factorial basis of characters—made great progress. By 1910, the validity of Mendelism was widely recognized and the field William Bateson christened `genetics' was complemented by the chromosome theory of heredity of T. H. Morgan and his group in the United States. Historians, however, have largely overlooked an important factor in the early establishment of Mendelism and genetics: the large number of women who contributed to the various research groups. This article examines the social, economic, and disciplinary context behind this new wave of women's participation in science and describes the work of women Mendelians and geneticists employed at three leading experimental research institutes, 1900-1940. It argues that the key to more women working in science was the access to higher education and the receptivity of emerging interdisciplinary fields such as genetics to utilize the expertise of women workers, which not only advanced the discipline but also provided new opportunities for women's employment in science.

    Full Text Available Gregor Mendel attended lectures of F. Diebl, professor of natural history and agricultural science at the Institute of Philosophy in Brno. Diebl published his lectures in a textbook “Abhandlungen über die allgemeine und besondere Naturgeschichte, Brünn 1835.” From the textbook the level of scientific knowledge in plant biology is obvious, with which the later founder of a new field of biology – genetics got acquainted. Diebl considered germination to be a specific method of fermentation transforming seed starch into a sugary matter which nourishes the germinating plant. In the physiology of nutrition he distinguished nutrition from the soil via roots from nutrition from the air via leaves. The former is based primarily on the humus theory of A. Thaer (1809 because not until 5 years after the publication of Diebl’s textbook J. Liebig initiated the mineral theory. Diebl’s presentation of photosynthesis was based on information available at that time about the release of oxygen by green plants under conditions of light and the uptake of CO2, but he had no knowledge about the passage of CO2 into the leaves through stomata. Remarkable is Diebl’s discovery that respiration increases during flowering. Electricity is considered to be a force significantly supporting the life processes of plants. Diebl also noticed the difference between diurnal and night evaporation of water from the leaves. In his textbook growth is connected with nutrition only, as it was the entire 19th century. Stem thickening from the cambium is described very simply. Bud and root regeneration is given the term reproduction which today is commonly used in relation to sexual reproduction. Diebl considered nyctinastic movements (bending or unbending of the leaves and closing of the flowers at night to be “sleep”. He described fertilisation in a primitive way, because it was not until 1848 that the first exact description came out.

  13. Modernity in medicine and hygiene at the end of the 19th century: the example of cremation

    Directory of Open Access Journals (Sweden)

    Alessandro Porro

    2012-02-01

    Full Text Available Medicine in the second half of the nineteenth century takes on some characteristics of modernity. These characteristics are worthy of our attention because they help us to understand better some of the current problems of hygiene and public health. One of the topics that was most discussed in the scientific-academic milieu of the second half of the nineteenth century was cremation. There was a poetic precedent: the cremation of Percy Bysse Shelley (1792-1822. The earliest apparatus to completely destroy the corpse was made in Italy and Germany in the 1870s. As far as hygiene was concerned, the reasons for cremation were not to pollute the water-bearing strata and an attempt to streamline the cemetery structure. As in an apparent schizophrenia, scientists of the day worked to both destroy and preserve corpses. There is also the unusual paradox that when the first cremations took place, the corpses were first preserved then to be destroyed later. The catholic world (mainly in Italy and forensic scientists opposed cremation. It was left to the hygienists to spread the practice of cremation. An analysis of scientific literature shows us that if we leave out the related forensic and ethical problems, recent years have seen attention paid to any harmful emissions from crematoria equipment which have poured into the environment. Another issue is the assessment of inadvertent damage which may be caused by the condition of the corpse. Some topics, however, such as the need for preventive autopsies (first proposed in 1884 in Milan are still a subject of debate, and seem to pass virtually unchanged from one generation to the next.

    Mohr, P.

    John Birmingham (1814-1884) of Millbrook, County Galway, was an outstanding amateur astronomer, now completely forgotten. He discovered the 1866 nova, T Coronae Borealis. Later his name was assigned to a feature near Anaxagoras on the Moon. In 1884 the Royal Irish Academy awarded him its Cunningham Gold Medal for his catalogue of the red variable stars. John Birmingham was not only an acute observer, he also wrote numerous semi-popular articles on many aspects of astronomy. He was also active in geology and railway surveying.

  8. Applying Mendelian rules in rapeseed (Brassica napus breeding

    Directory of Open Access Journals (Sweden)

    Marjanović-Jeromela Ana

    2016-01-01

    Full Text Available Rapeseed is one of the most important sources of edible oil, raw material for industry, as well as feed. The yield and quality of rapeseed have significantly been improved in recent decades as a result of intensive breeding and optimized production technology. The application of Mendel's rules in introducing monogenic traits has also contributed to success in rapeseed breeding. Rule 1, which refers to the uniformity of F1 generation, is now the basis of widespread development of rapeseed hybrids. Rule 2, dealing with genetic segregation in the F2 generation, is the basis for understanding the process of breeding lines. Rule 3, regarding the independent segregation of genes and traits, while exempting linked traits, is the basis of combining different desirable properties by selection. In the last few decades, the systematic use of Mendel's rules has contributed to the improvement of many properties of rapeseed, including tolerance to biotic and abiotic stress, yield and seed quality. Particular progress has been made in breeding for resistance to diseases, including the identification of molecular markers for marker-assisted selection. The next objective of rapeseed breeding is to create varieties with improved tolerance to environmental stress (e.g. frost, heat, and drought. Based on Mendel's rules, classical breeding methods and the latest developments in the field of molecular genetics and breeding, future progress is expected in the field of rapeseed breeding with an emphasis on polygenic, quantitative traits such as biomass, seed, and oil yield.

    Full Text Available During the last quarter of the XVIIIth century and the first quarter of the XIXth century, coinciding with the musical mastery of Buono Chiodi (1770-1782 and Melchor López (1783-1822 in the cathedral of Santiago de Compostela, an unusual proliferation of instrumental music took place in the Galician scene, revitalised in the particular case of Santiago by a powerful influence of the new foreign tendencies coming form Italy and the court of Madrid – an even from Paris, London, Lisbon or Porto. In this atmosphere, the Compostelan cathedral orchestra reached an enormous prominence which had never enjoyed previously and rarely achieved in the whole Hispanic area. Whitin the contemporary context – where music produced by ecclesiastic chapels usually built their instrumental groups according to the pattern without viola based on the baroque trio – the introduction and habitual presence of this instrument stands out in the Compostelan orchestral group. Recieving a surprising and unexpected impulse, viola was the object of many efforts, made both by musicians and the Chapter – staff of instruments for the chapel’s musicians, presence of specialized instrumentalists, works both copied and acquired which demanded the participation of two violas, etc. – concluded with its definitive adoption for the daily instrumental practice.

    Opsomming Die literatuur toon 'n leemte aan navorsing betreffende individuele attribute wat 'n persoon tot deelnemende bestuur mag predisponeer. Met hierdie studie is ondersoek ingestel na die verband tussen twee suike attribute, naamlik selfkonsep en mensbeskouing enersyds, en gewilligheid tot deelnemende bestuur andersyds. 'n Instrument gebaseer op McGregor se teorie, is ontwikkel om mensbeskouing binne werkkonteks te meet. Met behulp van faktorontleding is twee faktore onttrek wat onderskeidelik intrinsieke en ekstrinsieke aspekte van 'n persoon se beskouing van ander se houding teenoor werk meet. 'n Gelykkansige steekproef uit 233 toesighouers van 'n openbare versorgingsonderneming het 196 bruikbare vraelyste opgelewer. 'n Beduidende verband tussen selfkonsep en mensbeskouing enersyds, en gewilligheid tot deelnemende bestuur andersyds, is met behulp van kanoniese korrelasie gevind (r =0,601; p < 0,01.

  17. Genetic Determinism in the Genetics Curriculum. An Exploratory Study of the Effects of Mendelian and Weldonian Emphases

    Jamieson, Annie; Radick, Gregory

    2017-12-01

    Twenty-first-century biology rejects genetic determinism, yet an exaggerated view of the power of genes in the making of bodies and minds remains a problem. What accounts for such tenacity? This article reports an exploratory study suggesting that the common reliance on Mendelian examples and concepts at the start of teaching in basic genetics is an eliminable source of support for determinism. Undergraduate students who attended a standard `Mendelian approach' university course in introductory genetics on average showed no change in their determinist views about genes. By contrast, students who attended an alternative course which, inspired by the work of a critic of early Mendelism, W. F. R. Weldon (1860-1906), replaced an emphasis on Mendel's peas with an emphasis on developmental contexts and their role in bringing about phenotypic variability, were less determinist about genes by the end of teaching. Improvements in both the new Weldonian curriculum and the study design are in view for the future.

    Science.gov (United States)

    Prottas, David J; Nummelin, Mary Rogers

    Douglas McGregor's conceptualization of Theory X and Theory Y has influenced management practices for almost six decades, despite the relative paucity of empirical support. This empirical study examined the relationships between health care employees' perceptions of (1) manager Theory Y and Theory X orientations; (2) work unit psychological safety, organizational citizenship behavior, and service quality; and (3) the employing entity. The study used survey data from more than 3500 employees of a large US health care system and analyzed them using confirmatory factor and hierarchical regression analyses. Results indicate that McGregor's conceptualization is best considered as two separate constructs-Theory Y and Theory X-rather than as one-dimensional X/Y construct. This study's three dependent variables were positively related to Theory Y and negatively related to Theory X, with larger Theory Y effect sizes. Psychological safety partially mediated the relationship between Theory Y and the dependent variables Y. Practical implications are presented.

    In consequence of their growing use and demand, the inevitable environmental presence of nanomaterials (NMs) has raised concerns about their potential deleterious effects to aquatic environments. The carbon NM fullerene (C{sub 60}), which forms colloidal aggregates in water, and its water-soluble derivative fullerol (C{sub 60}(OH){sub 18-22}), which possesses antioxidant properties, are known to be photo-excited by ultraviolet (UV) or visible light. To investigate their potential hazards to aquatic organisms upon exposure to UV sunlight, this study analyzed (a) the in vitro behavior of fullerene and fullerol against peroxyl radicals (ROO{center_dot}) under UV-A radiation and (b) the effects of these photo-excited NMs on oxidative stress parameters in functional gills extracted from the fish Cyprinus carpio (Cyprinidae). The variables measured were the total antioxidant capacity, lipid peroxidation (TBARS), the activities of the antioxidant enzymes glutathione reductase (GR) and glutamate cysteine ligase (GCL), and the levels of the non-enzymatic antioxidant glutathione (GSH). The obtained results revealed the following: (1) both NMs behaved in vitro as antioxidants against ROO{center_dot} in the dark and as pro-oxidants in presence of UV-A, the latter effect being reversed by the addition of sodium azide, which is a singlet oxygen ({sup 1}O{sub 2}) quencher; (2) fullerene induced toxicity with or without UV-A incidence, with a significant (p < 0.05) increase in lipid peroxidation (with greater damage under illumination), a decrease in GCL activity, and the depletion of GSH stocks (under illumination), all of which were attributed to {sup 1}O{sub 2} generation; and (3) fullerol also decreased GCL activity and GSH formation (p < 0.05) but without lipid damage. The overall results show that fullerene can be toxic with or without light incidence, whereas UV radiation seems to play a key role in the environmental toxicity of carbon NMs through {sup 1}O{sub 2} formation.

    Full Text Available Mode of Operation and Sustainability of Oreochromis niloticus (Linnaeus, 1758, Clarias gariepinus (Burchell, 1822 and Gymnarchus niloticus (Cuvier, 1829 Fisheries in the Sourou Dam Lake (Burkina Faso. This research on fishery exploitation in the Sourou dam raises the issue of sustainable management of common property. The central hypothesis is that the effectiveness of co-management for sustainable fishing practices is related to the level of ownership of that management and actors' games by fishing communities. In analysing co-management induced effects on fishing practices and exploitation of C. gariepinus, O. niloticus and G. niloticus species, related to its implementation in Sourou fishery, a research methodology that combines qualitative and quantitative methods is used. Socio-economic surveys were conducted with 30 fishermen in three villages bordering the fishery. Biological surveys were also conducted with catches of C. gariepinus, O. niloticus and G. niloticus of these fishermen,. The results indicate a weak ownership of the co-management model by fishermen and the strategies of actors that consist to minimize the costs of the sustainable management of fisheries resources at individual level. Indeed, even when informed of fisheries regulations, fishermen use prohibited fishing equipment (54.1% of the catches of studied species, and fishi illegally (43.3% of the fishermen. Furthermore, significant proportions of each studied species are captured before their first maturity sizes (52.2% of C. gariepinus, 15.8% of G. niloticus and 14.3% of O. niloticus. So, the central hypothesis is verified because the weak ownership of co-management by fishing communities and the actors' strategies do not encourage them to develop a responsible behavior for sustainable fishing.

    2010-01-01

    Japanese agricultural scientist Toyama Kametaro's report about the Mendelian inheritance of silkworm cocoon color in Studies on the Hybridology of Insects (1906) spurred changes in Japanese silk production and thrust Toyama and his work into a scholarly exchange with American entomologist Vernon Kellogg. Toyama's work, based on research conducted in Japan and Siam, came under international scrutiny at a time when analyses of inheritance flourished after the "rediscovery" of Mendel's laws of heredity in 1900. The hybrid silkworm studies in Asia attracted the attention of Kellogg, who was concerned with how experimental biology would be used to study the causes of natural selection. He challenged Toyama's conclusions that Mendelism alone could explain the inheritance patterns of silkworm characters such as cocoon color because they had been subject to hundreds of years of artificial selection, or breeding. This examination of the intersection of Japanese sericulture and American entomology probes how practical differences in scientific interests, societal responsibilities, and silkworm materiality were negotiated throughout the processes of legitimating Mendelian genetics on opposite sides of the Pacific. The ways in which Toyama and Kellogg assigned importance to certain silkworm properties show how conflicting intellectual orientations arose in studies of the same organism. Contestation about Mendelism took place not just on a theoretical level, but the debate was fashioned through each scientist's rationale about the categorization of silkworm breeds and races and what counted as "natural". This further mediated the acceptability of the silkworm not as an experimental organism, but as an appropriately "natural" insect with which to demonstrate laws of inheritance. All these shed light on the challenges that came along with the use of agricultural animals to convincingly articulate new biological principles.

  5. Theories for the winds from Wolf Rayet stars

    International Nuclear Information System (INIS)

    Cassinelli, J.P.

    1982-01-01

    The massive and fast winds of Wolf Rayet stars present a serious momentum problem for the line-driven wind theories that are commonly used to explain the fast winds of early type stars. It is perhaps possible for the winds to be driven by lines, if multiple scattering occurs and if there are a sufficient number of lines in the spectrum so that large fraction of the continuum is blocked by line opacity in the winds. Several other mechanisms are discussed, in particular two that rely on strong magnetic fields: a) Alfven wave driven wind models like those recently developed by Hartmann and MacGregor for late type supergiants and b) the ''Fast Magnetic Rotator'' model that was developed by Belcher and MacGregor for the winds from pre-main sequence stars. In either model, large magnetic fields (approximately equal to 10 4 gauss) are required to drive the massive and fast winds of Wolf Rayet stars. Smaller fields might be possible if the multiple scattering line radiation force can be relied on to provide a final acceleration to terminal velocity. (Auth.)

    Full Text Available The first paper banknotes of the Privileged National Bank: 100 dinars in gold, 50 dinars in gold and 10 dinars in silver, were placed in circulation in 1884 and 1885. The 100-dinar banknote was put in circulation on 2 July 1884, when the Privileged National Bank of the Kingdom of Serbia commenced its operations. The banknotes, especially the 100- and 50-dinar ones, were issued as temporary, with the major assistance of the Belgium National Bank. Given that until then Serbia only had coins in circulation, the paper 100- and 50-dinar banknotes were met with distrust and for quite a while there were problems in respect of their usage. The shortest lifetime had the 50-dinar banknote, due to its poor quality and consequent easy counterfeiting.

    With an objective of creating ultra-high density organic photo recording elements for photon mode recording and rewritable wavelength multiplex recording by utilizing control of association status of photochromic compound, research and development has been performed. This paper summarizes the achievements in fiscal 1989. In developing the materials, verification was made on effectiveness of the newly structured positive polarity model. The method was used to attempt synthesis of four kinds of new spiropyrane, among which it was discovered that BSP1822 forms J-association complex in the long wavelength region. In the thin film forming technology, the J-association complex of BSP1822 was stabilized successfully in the film mixed with bi-molecular film forming material. In order to develop a technology to form dry photochromic thin films, an organic molecular beam epitaxial device and a thin film structure analyzer were introduced. In the elucidation and research on fundamental properties, discussions were given on properties of the SP1822LB film revealed by the steady-state light and laser pulse light. Furthermore, the molecular orientation of the SP1801 on the air-water interface was investigated, and molecular models on the air-water interface were considered. (NEDO)

    Linseed is able to accumulate considerably high concentrations of Cd in generative organs, the dietary critical value of 0.3 {mu}g Cd/g seed often being exceeded. Differences between genotypes of linseed in this respect, however, have been observed but the underlying mechanisms responsible for these differences are unknown. The aim of the present work was to identify these mechanisms by studying the Cd accumulation of the linseed genotypes Antares and McGregor which differ in their ability to accumulate Cd in the seeds. Cultivar Antares is a high and cv. McGregor is low Cd accumulator which was confirmed in a pot experiment. It was found that the differences between these genotypes were Cd-specific and were caused neither by single seed weight nor by Cd translocation into the shoot. The distribution pattern of Cd within mature capsules between the pericarp and the seeds differed from that of Ca which was used as a phloem-immobile reference ion. From these results we conclude that Cd was translocated from the pericarp into the seeds via the phloem. This conclusion was supported by direct Cd determination in collected phloem sap from linseed stems. As sources of seed-Cd we identified the pericarps of capsules and the leaves. The genotype differences concerning the Cd concentrations in the seeds may be explained in terms of differences in phloem translocation of Cd. (orig.)

    There are only three grand theories in biology: the theory of the cell, the theory of the gene, and the theory of evolution. Two of these, the cell and gene theories, originated in the study of plants, with the third resulting in part from botanical considerations as well. Mendel's elucidation of the rules of inheritance was a result of his experiments on peas. The rediscovery of Mendel's work in 1900 was by the botanists de Vries, Correns, and Tschermak. It was only in subsequent years that animals were also shown to have segregation of genetic elements in the exact same manner as had been shown in plants. The story of developmental biology is different - while the development of plants has long been studied, the experimental and genetic approaches to developmental mechanism were developed via experiments on animals, and the importance of genes in development (e.g., Waddington, 1940) and their use for understanding developmental mechanisms came to botanical science much later - as late as the 1980s.

    2012-06-01

    Full Text Available Abstract Background Here we present two new computer tools, PREMIM and EMIM, for the estimation of parental and child genetic effects, based on genotype data from a variety of different child-parent configurations. PREMIM allows the extraction of child-parent genotype data from standard-format pedigree data files, while EMIM uses the extracted genotype data to perform subsequent statistical analysis. The use of genotype data from the parents as well as from the child in question allows the estimation of complex genetic effects such as maternal genotype effects, maternal-foetal interactions and parent-of-origin (imprinting effects. These effects are estimated by EMIM, incorporating chosen assumptions such as Hardy-Weinberg equilibrium or exchangeability of parental matings as required. Results In application to simulated data, we show that the inference provided by EMIM is essentially equivalent to that provided by alternative (competing software packages such as MENDEL and LEM. However, PREMIM and EMIM (used in combination considerably outperform MENDEL and LEM in terms of speed and ease of execution. Conclusions Together, EMIM and PREMIM provide easy-to-use command-line tools for the analysis of pedigree data, giving unbiased estimates of parental and child genotype relative risks.

  9. Science beyond boundary: are premature discoveries things of the past?

    Science.gov (United States)

    Singh, Rama S

    2016-06-01

    Mendel's name more than of any other draws our attention to the personal side in terms of success and failure in science. Mendel lived 19 years after presenting his research findings and died without receiving any recognition for his work. Are premature discoveries things of the past, you may ask? I review the material basis of science in terms of science boundary and field accessibility and analyze the possibility of premature discoveries in different fields of science such as, for example, physics and biology. I conclude that science has reached a stage where progress is being made mostly by pushing the boundary of the known from inside than by leaping across boundaries. As more researchers become engaged in science, and as more publications become open access, on-line, and interactive, the probability of an important discovery remaining buried and going unrecognized would become exceedingly small. Of course, as examples from physics show, a new theory or an important idea can always lie low, unrecognized until it becomes re-discovered and popularized by other researchers. Thus, premature discoveries will become less likely but not forbidden.

Plasma boundary control in stellarators has been shown to be very effective in improving plasma performance [EPS 2001, Madeira, Portugal, 18-22 June 2001] and, accordingly, will be an important element from the very beginning of the NCSX design. Plasma-facing components will be developed systematically according to our understanding of the NCSX boundary, with the eventual goal to develop a divertor with all the benefits for impurity and neutrals control. Neutrals calculations have been started to investigate the effect of neutrals penetration at various cross-sections

    The El Paso County Geothermal Project at Fort Bliss was an effort to determine the scale and scope of geothermal resources previously identified on Fort Bliss’ McGregor Range in southern Otero County, New Mexico. The project was funded with a $5,000,000 grant to El Paso County from the U.S. Department of Energy (DOE) as part of the American Recovery and Reinvestment Act of 2009 and a $4,812,500 match provided by private sector partners. The project was administered through the DOE Golden Field Office to awardee El Paso County. The primary subcontractor to El Paso County and project Principal Investigator - Ruby Mountain Inc. (RMI) of Salt Lake City, Utah - assembled the project team consisting of Evergreen Clean Energy Management (ECEM) of Provo, Utah, and the Energy & Geoscience Institute at the University of Utah (EGI) in Salt Lake City, UT to complete the final phases of the project. The project formally began in May of 2010 and consisted of two preliminary phases of data collection and evaluation which culminated in the identification of a drilling site for a Resource Confirmation Well on McGregor Range. Well RMI 56-5 was drilled May and June 2013 to a depth of 3,030 ft. below ground level. A string of slotted 7 inch casing was set in 8.75 inch hole on bottom fill at 3,017 ft. to complete the well. The well was drilled using a technique called flooded reverse circulation, which is most common in mineral exploration. This technique produced an exceptionally large and complete cuttings record. An exciting development at the conclusion of drilling was the suspected discovery of a formation that has proven to be of exceptionally high permeability in three desalinization wells six miles to the south. Following drilling and preliminary testing and analysis, the project team has determined that the McGregor Range thermal anomaly is large and can probably support development in the tens of megawatts.

  20. Noble gas composition of subcontinental lithospheric mantle: An extensively degassed reservoir beneath Southern Patagonia

    2016-09-01

    Patagonia, in the Southern Andes, is one of the few locations where interactions between the oceanic and continental lithosphere can be studied due to subduction of an active spreading ridge beneath the continent. In order to characterize the noble gas composition of Patagonian subcontinental lithospheric mantle (SCLM), we present the first noble gas data alongside new lithophile (Sr-Nd-Pb) isotopic data for mantle xenoliths from Pali-Aike Volcanic Field and Gobernador Gregores, Southern Patagonia. Based on noble gas isotopic compositions, Pali-Aike mantle xenoliths represent intrinsic SCLM with higher (U + Th + K)/(3He, 22Ne, 36Ar) ratios than the mid-ocean ridge basalt (MORB) source. This reservoir shows slightly radiogenic helium (3He/4He = 6.84-6.90 RA), coupled with a strongly nucleogenic neon signature (mantle source 21Ne/22Ne = 0.085-0.094). The 40Ar/36Ar ratios vary from a near-atmospheric ratio of 510 up to 17700, with mantle source 40Ar/36Ar between 31100-6800+9400 and 54000-9600+14200. In addition, the 3He/22Ne ratios for the local SCLM endmember, at 12.03 ± 0.15 to 13.66 ± 0.37, are higher than depleted MORBs, at 3He/22Ne = 8.31-9.75. Although asthenospheric mantle upwelling through the Patagonian slab window would result in a MORB-like metasomatism after collision of the South Chile Ridge with the Chile trench ca. 14 Ma, this mantle reservoir could have remained unhomogenized after rapid passage and northward migration of the Chile Triple Junction. The mantle endmember xenon isotopic ratios of Pali-Aike mantle xenoliths, which is first defined for any SCLM-derived samples, show values indistinguishable from the MORB source (129Xe/132Xe =1.0833-0.0053+0.0216 and 136Xe/132Xe =0.3761-0.0034+0.0246). The noble gas component observed in Gobernador Gregores mantle xenoliths is characterized by isotopic compositions in the MORB range in terms of helium (3He/4He = 7.17-7.37 RA), but with slightly nucleogenic neon (mantle source 21Ne/22Ne = 0.065-0.079).

  3. Darbishire expands his vision of heredity from Mendelian genetics to inherited memory.

    Science.gov (United States)

    Wood, Roger J

    2015-10-01

    The British biologist A.D. Darbishire (1879-1915) responded to the rediscovery in 1900 of Mendel's theory of heredity by testing it experimentally, first in Oxford, then in Manchester and London. He summarised his conclusions in a textbook 'Breeding and the Mendelian Discovery' (1911), in which he questioned whether Mendelism alone could explain all aspects of practical breeding experience. Already he had begun to think about an alternative theory to give greater emphasis to the widely held conviction among breeders regarding the inheritance of characteristics acquired during an individual's life. Redefining heredity in terms of a germ-plasm based biological memory, he used vocabulary drawn partly from sources outside conventional science, including the metaphysical/vitalistic writings of Samuel Butler and Henri Bergson. An evolving hereditary memory fitted well with the conception of breeding as a creative art aimed at greater economic efficiency. For evolution beyond human control he proposed a self-modifying process, claiming it to surpass in efficiency the chancy mechanism of natural selection proposed by Darwin. From his writings, including early chapters of an unfinished book entitled 'An Introduction to a Biology', we consider how he reached these concepts and how they relate to later advances in understanding the genome and the genetic programme.

  4. Specificities of the small and medium-sized enterprises in the Czech Republic and EU

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available Small and medium enterprises (SME are the engine of the European economy. They are an essential source of jobs, create entrepreneurial spirit and innovation in the EU and are thus crucial for fostering competitiveness and employment. In the enlarged European Union of 27 countries, some 20 million SMEs provide around 75 million jobs and represent 99 % of all enterprises. However, they are often confronted with market imperfections. SMEs frequently have difficulties in obtaining capital or credit, particularly in the early start–up phase. Their limited resources may also restrict access to new technology or innovation. It is therefore necessary to monitor the development of SMEs in individual EU countries and highlighting their problems and mainly to their importance.During the recent period of time there have been many researchers from the FBE Mendel University in Brno, who focused on the analysis of the small and medium-sized enterprise, e.g. Bohušová (2007; Chládková (2009; Nerudová a Bohušová (2008; Kubíčková a Peprný (2006; Zrůst a Pyšný (2008.

  5. The Connection Between the Woman’s Christian Temperance Union and the Prohibition Party

    Directory of Open Access Journals (Sweden)

    Adam Chamberlain

    2016-12-01

    Full Text Available Scholars have long been interested in the complementary relationships forged by membership groups and political parties. The post-bellum period presents an opportunity to consider these connections using a case study of two groups concerned with the ills of alcohol, the Woman’s Christian Temperance Union (WCTU and the Prohibition Party. Our analysis of presidential elections from 1876 to 1900 reveals that—although women were disenfranchised at the time—the WCTU’s organization and infrastructure was essential to early Prohibition Party success. In 1884, the first election after the two created a formal alliance in 1882, the strength of the WCTU helped the party grow its voter base. However, the two slowly diverged over how to achieve prohibition, and this relationship dissipated; there is little evidence of any significant connection between the groups after 1884. This supports the proposition that a shared means of accomplishing goals is an essential element of an effective group–party partnership.

    In this paper I analyze the conditions for scientific research and the social relationships that allowed the establishment of genetics in Mexico, in the laboratory, the clinic and in agronomy. I give three examples to illustrate how the cultural history of heredity has enlightened this work: the introduction and institutionalization of Mendelism in Mexico, the hereditarian ideas of medical doctors in the late nineteenth century, and the introduction of medical genetics in Mexico.

    Two hundred years ago, biologists did not recognize that there was such a thing as 'heredity'. By the 1830s, however, insights from medicine and agriculture had indicated that something is passed from generation to generation, creating the context for the brilliant advances of Mendel and Darwin. Recent work on the history and philosophy of science has shed light on how seventeenth-, eighteenth- and nineteenth-century thinkers sought to understand similarities between parents and offspring.

  17. Interference activity of a minimal Type I CRISPR–Cas system from Shewanella putrefaciens

    2015-01-01

    Type I CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats)–Cas (CRISPR-associated) systems exist in bacterial and archaeal organisms and provide immunity against foreign DNA. The Cas protein content of the DNA interference complexes (termed Cascade) varies between different CRISPR-Cas subtypes. A minimal variant of the Type I-F system was identified in proteobacterial species including Shewanella putrefaciens CN-32. This variant lacks a large subunit (Csy1), Csy2 and Csy3 and contains two unclassified cas genes. The genome of S. putrefaciens CN-32 contains only five Cas proteins (Cas1, Cas3, Cas6f, Cas1821 and Cas1822) and a single CRISPR array with 81 spacers. RNA-Seq analyses revealed the transcription of this array and the maturation of crRNAs (CRISPR RNAs). Interference assays based on plasmid conjugation demonstrated that this CRISPR-Cas system is active in vivo and that activity is dependent on the recognition of the dinucleotide GG PAM (Protospacer Adjacent Motif) sequence and crRNA abundance. The deletion of cas1821 and cas1822 reduced the cellular crRNA pool. Recombinant Cas1821 was shown to form helical filaments bound to RNA molecules, which suggests its role as the Cascade backbone protein. A Cascade complex was isolated which contained multiple Cas1821 copies, Cas1822, Cas6f and mature crRNAs. PMID:26350210

  8. Early history of the different forms of neurofibromatosis from ancient Egypt to the British Empire and beyond: First descriptions, medical curiosities, misconceptions, landmarks, and the persons behind the syndromes.

    Science.gov (United States)

    Ruggieri, Martino; Praticò, Andrea D; Caltabiano, Rosario; Polizzi, Agata

    2018-03-01

    The earliest examples of neurofibromatosis (in this case type 1, NF1) can be traced in the Ebers Papyrus (Ancient Egypt, 1.500 B.C.), in a Hellenistic statuette (Smyrna, 323 B.C.), in the coinage of the Parthians kings (247 B.C.) and in some 13th century monks' drawings. These earlier examples are somewhat less well defined as compared to the most recent better defined reports credited as having NF1 including an Inca child mummy (1480-1650 AD), Ulisse Aldrovandi's homuncio ("Monstrorum Historia", 1592 A.D.) with mosaic NF1 or the illustrations seen in the 18th century "Buffon's Histoire Naturelle" and "Cruveilhier's Anatomie Pathologique du Corps Human". The first English language report on NF1 was made by Akenside in 1768 and the first systematic review by Robert William Smith in 1849, while Virchow's pupil, Friedrich Daniel von Recklinghausen, in 1882, was the first to understand the origin of skin tumors and to name them neurofibromas. The touching story of Joseph C. Merrick (the "Elephant man," (who had Proteus syndrome and not NF1), in 1884, played an important role in the later misconception of NF1, as did the novel by Vicotr Hugo on the hunchback Quasimodo. The studies by van der Hoeve (1921), Yakovlev and Guthrie (1931), and Van Bogaert (1935), categorized "von Recklinghausen's" neurofibromatosis among the phakomatoses and the neurocutaneous syndromes. The first known mention of an acoustic neuroma (at autopsy) is attributed to Eduard Sandifort (1777 AD) while John H. Wishart made the earliest autoptic description of neurofibromatosis type 2 (NF2), in 1822, in a 21-year-old man with bilateral acoustic neuromas, who manifested signs since his infancy (Wishart subtype NF2). Smith likely described the first case of schwannomatosis in 1849. Older, Virchow, von Recklinghausen, and Verocay first classified "neuromas" and Masson and Penfield first used the word "schwannoma" taking it from Theodore Schwann's works. In 1903 Henneberg and Koch described NF2 in detail

    Iron deficiency (-Fe) is one of the major problems in crop production. Dicots, like pea (Pisum sativum L.), are Strategy I plants, which induce a group of specific enzymes such as Fe(III)-chelate reductase (FRO), Fe responsive transporter (IRT) and H(+)-ATPase (HA) at the root plasma membrane under -Fe. Different species and cultivars have been shown to react diversely to -Fe. Furthermore, different kinds of experimental set-ups for -Fe have to be distinguished: i) short-term vs. long-term, ii) constant vs. acute alteration and iii) buffered vs. unbuffered systems. The presented work compares the effects of constant long-term -Fe in an unbuffered system on roots of four different pea cultivars in a timely manner (12, 19 and 25days). To differentiate the effects of -Fe and plant development, control plants (+Fe) were analyzed in comparison to -Fe plants. Besides physiological measurements, an integrative study was conducted using a comprehensive proteome analysis. Proteins, related to stress adaptation (e.g. HSP), reactive oxygen species related proteins and proteins of the mitochondrial electron transport were identified to be changed in their abundance. Regulations and possible functions of identified proteins are discussed. Pea (Pisum sativum L.) belongs to the legume family (Fabaceae) and is an important crop plant due to high Fe, starch and protein contents. According to FAOSTAT data (September 2015), world production of the garden pea quadrupled from 1970 to 2012. Since the initial studies by Gregor Mendel, the garden pea became the most-characterized legume and has been used in numerous investigations in plant biochemistry and physiology, but is not well represented in the "omics"-related fields. A major limitation in pea production is the Fe availability from soils. Adaption mechanisms to Fe deficiency vary between species, and even cultivars have been shown to react diversely.

    Type I CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats)-Cas (CRISPR-associated) systems exist in bacterial and archaeal organisms and provide immunity against foreign DNA. The Cas protein content of the DNA interference complexes (termed Cascade) varies between different CRISPR-Cas subtypes. A minimal variant of the Type I-F system was identified in proteobacterial species including Shewanella putrefaciens CN-32. This variant lacks a large subunit (Csy1), Csy2 and Csy3 and contains two unclassified cas genes. The genome of S. putrefaciens CN-32 contains only five Cas proteins (Cas1, Cas3, Cas6f, Cas1821 and Cas1822) and a single CRISPR array with 81 spacers. RNA-Seq analyses revealed the transcription of this array and the maturation of crRNAs (CRISPR RNAs). Interference assays based on plasmid conjugation demonstrated that this CRISPR-Cas system is active in vivo and that activity is dependent on the recognition of the dinucleotide GG PAM (Protospacer Adjacent Motif) sequence and crRNA abundance. The deletion of cas1821 and cas1822 reduced the cellular crRNA pool. Recombinant Cas1821 was shown to form helical filaments bound to RNA molecules, which suggests its role as the Cascade backbone protein. A Cascade complex was isolated which contained multiple Cas1821 copies, Cas1822, Cas6f and mature crRNAs. © The Author(s) 2015.

    Full Text Available José Ignacio Moreno es uno de los fundadores de la independencia del Perú. En calidad de tal acompañó el proyecto del General rioplatense José de San Martín de transformar en 1822 la monarquía peruana en un reino independiente. Pero, a diferencia de la multitud de sus contemporáneos, la historiografía apenas lo presenta como un circunstante en la epopeya de la emancipación, de quien no se conserva ni un retrato. El motivo es la extraña adherencia de este personaje a las ideas del ultramontanismo y su temprana cercanía con la obra del contrarrevolucionario francés Joseph de Maistre. Un discurso monárquico extremista en 1822 lo colocaría como el fundador involuntario del Perú como República.

His classification of space becomes a portal to imagination, creating a prism in which all physical worlds and objects are enhanced by individual or artistic inner visions and dreams, forming most insightful dialectics of inside and outside, open and closed, being and non-being: leading to what he finally calls 'the phenomenology of roundness' in art and philosophical thinking.

    The spider mite, Eotetranychus lewisi (McGregor) (Acari: Tetranychidae), is a new emerging pest in California commercial strawberries. The predatory mite Phytoseiulus persimilis (Athias-Henriot) (Acari: Phytoseiidae), typically used for biocontrol of Tetranychus urticae (Koch) (Acari: Tetranychidae), provided growers little to no control of E. lewisi. Four commonly used phytoseiid predatory mites: P. persimilis, Neoseiulus californicus (McGregor), N. fallacis (Garman), and Amblyseius andersoni (Chant), were used in lab studies to investigate which is best at managing E. lewisi populations. We als o investigated t he interactions between T. urticae and E. lewisi and in relation to phytoseiid efficiency given the potential for indirect effects of biocontrol. When E. lewisi and T. urticae are present on the same leaf, T. urticae populations increase and begin displacing E. lewisi. P. persimilis did not feed on E. lewisi, but the other three predatory mites consumed the spider mites and lowered their populations. When both E. lewisi and T. urticae are present on the same leaf, N. fallacis and A. andersoni fed on both types of mites equally and were capable of decreasing both populations. N. californicus fed on E. lewisi first and decreased its population, but allowed T. urticae populations to increase. P. persimilis may be insufficient at controlling E. lewisi and its use may instead enhance E. lewisi populations.

    The potentiometric titration of a weakly basic carboxyl cation exchanger, obtained via alkaline hydrolysis of an acrylonitrile copolymer with divinyl benzene (degree of crosslinking, 12%) in a wide range of variation in a solution of pH (2-12) and NaCl (concentration 0.01, 0.1, 0.5, 1 M), is considered. The maximum ion-exchange capacity of the ion exchanger for Na+ is determined (10.10 ± 0.088 mmol/g of the dry mass) and found to be independent of the solution's ionic strength. It is established that in the investigated range of NaCl concentrations and pH, the acid-base balance is adequately described by Gregor's equation. The parameters of this equation are calculated as a function of the NaCl concentration: p K a = 8.13 ± 0.04, n = 1.50 ± 0.02 for 0.01 M; p K a = 6.56 ± 0.04, n = 2.60 ± 0.07 for 0.1 M; and p K a = 5.66 ± 0.6, n = 2.62 ± 0.06 for 0.5 and 1 M. It is shown that to describe the acid-base balance correctly within the proposed model we must estimate the adequacy of the experimental and calculated values of the ion exchanger's capacity at each pH value according to the calculated parameters of Gregor's equation.

  4. Sunspot number recalibration: The ~1840–1920 anomaly in the observer normalization factors of the group sunspot number

    2017-01-01

    Full Text Available We analyze the normalization factors (k′-factors used to scale secondary observers to the Royal Greenwich Observatory (RGO reference series of the Hoyt & Schatten (1998a, 1998b group sunspot number (GSN. A time series of these k′-factors exhibits an anomaly from 1841 to 1920, viz., the average k′-factor for all observers who began reporting groups from 1841 to 1883 is 1.075 vs. 1.431 for those who began from 1884 to 1920, with a progressive rise, on average, during the latter period. The 1883–1884 break between the two subintervals occurs precisely at the point where Hoyt and Schatten began to use a complex daisy-chaining method to scale observers to RGO. The 1841–1920 anomaly implies, implausibly, that the average sunspot observer who began from 1841 to 1883 was nearly as proficient at counting groups as mid-20th century RGO (for which k′ = 1.0 by definition while observers beginning during the 1884–1920 period regressed in group counting capability relative to those from the earlier interval. Instead, as shown elsewhere and substantiated here, RGO group counts increased relative to those of other long-term observers from 1874 to ~1915. This apparent inhomogeneity in the RGO group count series is primarily responsible for the increase in k′-factors from 1884 to 1920 and the suppression, by 44% on average, of the Hoyt and Schatten GSN relative to the original Wolf sunspot number (WSN before ~1885. Correcting for the early “learning curve” in the RGO reference series and minimizing the use of daisy-chaining rectifies the anomalous behavior of the k′-factor series. The resultant GSN time series (designated GSN* is in reasonable agreement with the revised WSN (SN*; Clette & Lefèvre 2016 and the backbone-based group sunspot number (RGS; Svalgaard & Schatten 2016 but significantly higher than other recent reconstructions (Friedli, personal communication, 2016; Lockwood et al. 2014a, 2014b; Usoskin et al. 2016a.

    Emphatically discusses the relationship between graft hybridization and the specificity of heredity in fruit trees on the basis of introducing the recent achievements in plant graft hybridization. We propose that genetic materials in rootstock being translocated and integrated into the genome of the germ cells and embryonic cells in scion are the main reasons why the majority of the hybrid seedlings have wild properties and the heredity of fruit trees violate Mendel's laws of heredity. The potential of graft hybridization in fruit breeding are also discussed.

    The authors present a method for the calculation of the dose equivalent rate which takes main isotopes as well as minority isotopes into account. According to this method, they first calculate the initial composition (before ageing) from what can be observed at a certain time. Then, from this reconstructed initial composition, they complete the isotopic assessment, thus the sources of emitted particles at the same time. The method is implemented in the MENDEL code. Validation is performed with data corresponding to an UOX fuel pin

  8. From Darwin's Origin of Species toward a theory of natural history.

    Science.gov (United States)

    Boero, Ferdinando

    2015-01-01

    Darwin is the father of evolutionary theory because he identified evolutionary patterns and, with Natural Selection, he ascertained the exquisitely ecological ultimate processes that lead to evolution. The proximate processes of evolution he proposed, however, predated the discovery of genetics, the backbone of modern evolutionary theory. The later discovery of the laws of inheritance by Mendel and the rediscovery of Mendel in the early 20th century led to two reforms of Darwinism: Neo-Darwinism and the Modern Synthesis (and subsequent refinements). If Darwin's evolutionary thought required much refinement, his ecological insight is still very modern. In the first edition of The Origin of Species, Darwin did not use either the word "evolution" or the word "ecology". "Ecology" was not coined until after the publication of the Origin. Evolution, for him, was the origin of varieties, then species, which he referred to as well-marked varieties, whereas, instead of using ecology, he used "the economy of nature". The Origin contains a high proportion of currently accepted ecological principles. Darwin labelled himself a naturalist. His discipline (natural history) was a blend of ecology and evolution in which he investigated both the patterns and the processes that determine the organization of life. Reductionist approaches, however, often keep the two disciplines separated from each other, undermining a full understanding of natural phenomena that might be favored by blending ecology and evolution through the development of a modern Theory of Natural History based on Darwin's vision of the study of life.

    Full Text Available In this work we study the significance of the doceañista liberalism in the transformation of the Spanish monarchy, and in the construction of the Mexican State-nation from 1821. For that purpose, from the historical methodology we discuss the idea of «doceañista liberalism» while at the same time focusing on the relevance it acquired in the debates of the Mexican constituent Congress of 1822.

    En este estudio intentamos abordar la significación del liberalismo doceañista en la transformación de la monarquía hispánica y su trascendencia en la construcción del Estado-nación mexicano a partir de 1821. Para ello interpretamos desde la metodología histórica la noción de «liberalismo doceañista» al tiempo que argumentamos su importancia en los debates del congreso constituyente mexicano de 1822.

  8. Contactless sub-millimeter displacement measurements

    2008-07-01

    Weather effects on foldable domes, as used at the DOT and GREGOR, are investigated, in particular the correlation between the wind field and the stresses caused to both metal framework and tent clothing. Camera systems measure contactless the displacement of several dome points. The stresses follow from the measured deformation pattern. The cameras placed near the dome floor do not disturb telescope operations. In the set-ups of DOT and GREGOR, these cameras are up to 8 meters away from the measured points and must be able to detect displacements of less than 0.1 mm. The cameras have a FireWire (IEEE1394) interface to eliminate the need for frame grabbers. Each camera captures 15 images of 640 × 480 pixels per second. All data is processed on-site in real-time. In order to get the best estimate for the displacement within the constraints of available processing power, all image processing is done in Fourier-space, with all convolution operations being pre-computed once. A sub-pixel estimate of the peak of the correlation function is made. This enables to process the images of four cameras using only one commodity PC with a dual-core processor, and achieve an effective sensitivity of up to 0.01 mm. The deformation measurements are well correlated to the simultaneous wind measurements. The results are of high interest to upscaling the dome design (ELTs and solar telescopes).
