    Full Text Available Female pseudohermaphroditism represents discrepancy between karyotype and gonadal features on one side and a psychogenic phenotype on the other. Congenital adrenal hyperplasia is the part of the spectrum of female pseudohaermaofroditism and is due to an enzyme deficiency in steroidogenesis. More than 95% of patients have 21 hydroxylase deficiency which leads to a lack of cortisol and ACTH hypersecretion of pituitary, overproduction of 17 hydroxy progesterone (17OHP and androgens and adrenal cortex hyperplasia. The clinical phenotype is classified as classical and nonclassical (aka. 'Late onset' form. The classic form is represented as salt-waisting and simply virilizing, depending on the degree of lack of aldosterone. Pathophysiology of CAH due to the lack of 21α hydroxylase is closely associated with the degree of enzyme deficiency. Overproduction of androgens is leading to accelerated virilisation. Classical form is manifested in childhood and is characterized by the overproduction of cortisol precursors and adrenal androgens. In the most severe form, co-aldosterone deficiency leads to loss of salt with all the complications. Girls with the classical form of CAH typically have am ambiguous genitals at birth due to high concentrations of androgens in utero. CAH due to 21OH deficiency is the most common cause of ambiguous genitals in 46XX newborns. Characteristically, the clitoris is enlarged, partially fused labia maiora and a common urogenital sinus at the site of the urethra and vagina. The uterus, Fallopian tubes and ovaries are present and normal, a structures of Wolfian duct are absent. When diagnosed in childhood 46XX CAH patients has been assigned female gender so far, even in fully expressed in virilised external genitalia. This dogmatic approach is based on preserving fertility, and if there was at least uterus, opting for female sex was considered justified. Only about 5% of 46 patients with XX KAH has a psychogenic male gender, as

    Full Text Available Los últimos 25 años del siglo XX han supuesto un sustancial cambio en el modelo de crecimiento de la población andaluza. Así, mientras la caída de la fecundidad y la estabilización de las tasas de mortalidad han contribuido a un progresivo retroceso de la vitalidad natural, la masiva emigración de antaño ha dado paso al papel de Andalucía como incipiente foco de inmigración y al creciente protagonismo de movimientos internos de relocalización de la población. Desde el punto de vista territorial estas afirmaciones quedan matizadas por los notables contrastes que se producen entre los distintos ámbitos que conforman la región y que contraponen al medio rural con el urbano, al litoral con el interior o a las grandes ciudades con sus periferias.

    Full Text Available Prenatal diagnosis of simultaneous occurrence of chimerism and autosomal mosaicism is extremely rare. We report the prenatal diagnosis and genetic analysis of a fetus in a twin pregnancy with mosaic 47,XX,+21/46,XX with chimeric XX/XY. A 36-year-old, para 1, woman was referred for genetic counseling at 20 weeks' gestation because of abnormal karyotype (47,XX,+21/46,XX in one fetus in a twin pregnancy. Cordocentesis revealed 47,XX,+21[3]/46,XX[35]/46,XY[7] in this fetus. Postnatal cytogenetic analysis of cord blood confirmed three cell lines in this twin (A and 46,XY in the co-twin (B. Postmortem pathologic findings of both fetuses were normal. Fluorescence in situ hybridization identified three cell lines in the cord blood of twin A. Molecular genetic analysis using polymorphic DNA markers revealed parental origin of fetal tissue, and confirmed the chimeric status. Molecular genetic analysis with polymorphic DNA markers help to differentiate chimerism from mosaicism and define the origin of cell lines, which may have importance in genetic counseling.

    2007-11-01

    Isotropic XX models of one-dimensional spin-1/2 chains are investigated with the aim to elucidate the formal structure and the physical properties that allow these systems to act as channels for long-distance, high-fidelity quantum teleportation. We introduce two types of models: (i) open, dimerized XX chains, and (ii) open XX chains with small end bonds. For both models we obtain the exact expressions for the end-to-end correlations and the scaling of the energy gap with the length of the chain. We determine the end-to-end concurrence and show that model (i) supports true long-distance entanglement at zero temperature, while model (ii) supports “quasi-long-distance” entanglement that slowly falls off with the size of the chain. Due to the different scalings of the gaps, respectively exponential for model (i) and algebraic in model (ii), we demonstrate that the latter allows for efficient qubit teleportation with high fidelity in sufficiently long chains even at moderately low temperatures.

  17. The genetics of XX gonadal dysgenesis

    Energy Technology Data Exchange (ETDEWEB)

    Aittomaeki, K. (Univ. of Helsinki (Finland))

    1994-05-01

    In a nationwide population-based study of women born between 1950 and 1976, 75 patients with XX gonadal dysgenesis (XXGD) were identified in Finland. Patients were ascertained through hospital records and the registers of chromosome laboratories. In one family 4 daughters were affected; in six families 2 daughters were affected; and 57 cases were isolated. In one additional family the two affected females were in successive generations. Population records were utilized to trace ancestors of patients back to the beginning of the 19th century, in most cases. Consanguinity was detected in 8 (12%) of 66 families. When females only are considered, the segregation analyses yield a proportion of .23 affected. The relatively large number of affected individuals identified (incidence 1 in 8,300 live-born girls) implies a high gene frequency in the Finnish population. The geographic distribution was highly uneven, with most families originating in the sparsely populated north-central part of Finland. These findings support the existence of an autosomal recessive (XXGD) gene (locus designation [open quotes]ODG1[close quotes]) that is highly enriched in Finland. The multiplex families already identified will make it possible to map the ODG1 gene by a random search for linkage by using polymorphic markers. Linkage-disequilibrium analysis in the sporadic patients will then be used to test for genetic homogeneity versus heterogeneity. 27 refs., 3 figs.

  19. Inherited XX sex reversal originating from wild medaka populations.

    2010-11-01

    The teleost fish, medaka (Oryzias latipes), has an XX/XY sex-determining mechanism. A Y-linked DM domain gene, DMY, has been isolated by positional cloning as the sex-determining gene in this species. Previously, we conducted a field survey of genotypic sex and found that approximately 1% of wild medaka are sex-reversed (XX males and XY females). Here, we performed genetic analyses of nine spontaneous XX sex-reversed males to elucidate its genetic basis. In all cases, the F(1) progeny were all females, whereas XX males reappeared in the backcross (BC) progeny, suggesting that XX sex reversal is a recessive trait. Although the incidences of sex reversal in the BC progeny were mostly low, 40% were males derived from one XX male. We performed linkage analysis using 55 BC males and located a single major factor, sda-1 (sex-determining autosomal factor-1), controlling sex reversal in an autosomal linkage group. Thus, genes involved in the sex-determining pathway can be isolated from spontaneous mutants in wild populations.

    The testis-determining gene SRY is not well-conserved among mammals, particularly between mouse and other mammals, both in terms of protein structure and of expression regulation. To evaluate SRY phylogenic conservation in regards to its function, we expressed the goat gene (gSRY) in XX transgenic mouse gonads. Here, we show that gSRY induces testis formation, despite a goat expression profile. Our results demonstrate that sex-reversal can be induced in XX-mice by a non-mouse SRY thus suggesting a conserved molecular mechanism of action of this testis-determining gene across mammalian species.

  6. X chromosome activity in mouse XX primordial germ cells.

    Directory of Open Access Journals (Sweden)

    Susana M Chuva de Sousa Lopes

    2008-02-01

    Full Text Available In the early epiblast of female mice, one of the two X chromosomes is randomly inactivated by a Xist-dependent mechanism, involving the recruitment of Ezh2-Eed and the subsequent trimethylation of histone 3 on lysine 27 (H3K27me3. We demonstrate that this random inactivation process applies also to the primordial germ cell (PGC precursors, located in the proximal region of the epiblast. PGC specification occurs at about embryonic day (E7.5, in the extraembryonic mesoderm, after which the germ cells enter the endoderm of the invaginating hindgut. As they migrate towards the site of the future gonads, the XX PGCs gradually lose the H3K27me3 accumulation on the silent X chromosome. However, using a GFP transgene inserted into the X chromosome, we observed that the XX gonadal environment (independently of the gender is important for the substantial reactivation of the inactive X chromosome between E11.5 and E13.5, but is not required for X-chromosome reactivation during the derivation of pluripotent embryonic germ cells. We describe in detail one of the key events during female PGC development, the epigenetic reprogramming of the X chromosome, and demonstrate the role of the XX somatic genital ridge in this process.

    Qin, Wan; Guo, Jin-Liang

    2015-07-01

    We investigate the thermal quantum correlations in the Heisenberg XX spin chain, and the teleportation of a two-qubit entangled state via the spin chain is analyzed. It is found that the effects of external magnetic field and three-site interaction on the thermal entanglement and quantum discord between the nearest or the next nearest neighbor qubits behave differently in various aspects. Special attention is paid to how to enhance the quantum correlations of the output state and the average fidelity of the teleportation. We find that quantum discord gives a better performance in the quantum correlations transmission, and the three-site interaction is necessary for a successful teleportation.

  12. Investigation of KIT gene mutations in women with 46,XX spontaneous premature ovarian failure

    Directory of Open Access Journals (Sweden)

    Nelson Lawrence M

    2002-08-01

    Full Text Available Abstract Background Spontaneous premature ovarian failure presents most commonly with secondary amenorrhea. Young women with the disorder are infertile and experience the symptoms and sequelae of estrogen deficiency. The mechanisms that give rise to spontaneous premature ovarian failure are largely unknown, but many reports suggest a genetic mechanism in some cases. The small family size associated with infertility makes genetic linkage analysis studies extremely difficult. Another approach that has proven successful has been to examine candidate genes based on known genetic phenotypes in other species. Studies in mice have demonstrated that c-kit, a transmembrane tyrosine kinase receptor, plays a critical role in gametogenesis. Here we test the hypothesis that human KIT mutations might be a cause of spontaneous premature ovarian failure. Methods and Results We examined 42 women with spontaneous premature ovarian failure and found partial X monosomy in two of them. In the remaining 40 women with known 46,XX spontaneous premature ovarian failure we evaluated the entire coding region of the KIT gene. We did this using polymerase chain reaction based single-stranded conformational polymorphism analysis and DNA sequencing. We did not identify a single mutation that would alter the amino acid sequence of the c-KIT protein in any of 40 patients (upper 95% confidence limit is 7.2%. We found one silent mutation at codon 798 and two intronic polymorphisms. Conclusion Mutations in the coding regions of the KIT gene appear not to be a common cause of 46,XX spontaneous premature ovarian failure in North American women.

    We report on the development of high power, 9xx-10xx nm laser diode bars for use in direct diode systems and for solidstate and fibre laser pumping with applications in industrial markets. For 1 cm wide bars on micro channel cooler (MCC) we have achieved a reliable output power of 250 W across the 900 nm - 1060 nm range. At this output power level we have achieved power conversion efficiencies of 65-66 % and 90 % power content slow axis beam divergence of ~6.5°. Results of a 6400 h life test show an average power degradation of 0.6 % per 1000 h at this operating power level. We will also show results of high power bars assembled on the new OCLARO conductive cooler, the BLM. This new cooler has a small footprint of 12.6 mm × 24.8 mm and is designed for lateral or vertical stacking of diodes in multi kilowatt systems but with the benefits associated with a conductive cooler. The thermal properties are shown to be the same as for a standard CS mount. 1 cm wide high fill factor bars and 0.5 cm wide low fill factor half bars assembled on the BLM operate at 63-64 % power conversion efficiency (PCE) with output powers of up to 250 W and 150 W, respectively.

  20. XX sex reversal, palmoplantar keratoderma, and predisposition to squamous cell carcinoma: genetic analysis in one family.

    We describe a large inbred Sicilian family that includes four 46, XX (SRY-) brothers. Palmoplantar hyperkeratosis (PPK) and an associated predisposition to squamous cell carcinoma (SCC) of the skin, segregates as a recessive trait within the family. Interestingly, all the PPK-affected members of the family are phenotypic males (46,XY or 46,XX) while seven XX sibs are healthy phenotypic females with no signs of PPK. We propose that homozygosity for a single mutational event, possibly including contiguous genes, may cause PPK/SCC in both XY or XX individuals and sex reversal in XX individuals. The family is informative for linkage analysis for the PPK trait and allows linkage exclusion for the sex reversal trait. Here we show that 15 loci involved in PPK etiology, skin differentiation, function or malignancy, and nine loci involved in sex determination/differentiation are not implicated in the phenotype of this family.

    Full Text Available The article deals with objective and subjective tendencies of development of primary, secondary and higher education in the countries west, inhabited by immigrants from Ukraine. It is proved that during the XX century Ukrainian emigration schooling went that evolutional way, which other nations did in foreign environment. Unlike schools that existed in the USSR, the emigrants kept schools at their own expense and only in some cases the state assumed the obligation to teach Ukrainian children (Czechoslovakia, Canada. In the history of pedagogy the activity of school of Ukrainian studies outside the motherland – is a unique example of preservation of national identity, instilling in the younger generation the knowledge about Ukraine, its customs and traditions. The practice proves that children, who learned early the basics of the Ukrainian language and literature in foreign environment, fluently speak their native language during their lives.

  2. Entanglement spectrum and entangled modes of random XX spin chains

    2013-08-01

    In this paper, we study the ground-state entanglement properties of finite XX spin-1/2 chains with random couplings using the Jordan-Wigner transformation. We divide the system into two parts and study the reduced density matrices (RDMs) of its subsystems. Due to the free-fermion nature of the problem, the RDMs take the form of that of a free-fermion thermal ensemble. Finding the spectrum of the corresponding entanglement Hamiltonian and corresponding eigenvectors and comparing them with the real-space renormalization-group (RSRG) treatment, we establish the validity of the RSRG approach for entanglement in the limit of strong disorder but also find its limitations when disorder is weak. In the latter case, our paper provides a way to visualize the ``effective spins'' that form long-distance singlet pairs.

    We study finite size and temperature XX0 Heisenberg spin chain in weak and strong coupling regimes. By using an elegant connection of the model to integrable combinatorics and probability, we explore and interpret a possible phase structure of the model in asymptotic limit: the limit of large inverse temperature and size. First, the partition function and free energy of the model are derived by using techniques and results from random matrix models and nonintersecting Brownian motion. We show that, in the asymptotic limit, partition function of the model, written in terms of matrix integral, is governed by the Tracy–Widom distribution. Second, the exact analytic results for the free energy, which is obtained by the asymptotic analysis of the Tracy–Widom distribution, indicate a completely new and sophisticated phase structure of the model. This phase structure consists of second- and third-order phase transitions. Finally, to shed light on our new results, we provide a possible new interpretation of the phase structure in terms of dynamical behaviour of magnons in the spin chain. We demonstrate distinct features of the phases with schematic spin configurations which have definite features in each region of the phase diagram.

    Previous studies indicated that maturation inducing hormone, 17α, 20β-Dihydroxy-4-pregnen-3-one (DHP), probably through nuclear progestin receptor (Pgr), might be involved in spermatogenesis and oogenesis in fish. To further elucidate DHP actions in teleostean ovarian differentiation, we analyzed the expression of pgr in the ovary of Nile tilapia (Oreochromis niloticus), and performed RU486 (a synthetic Pgr antagonist) treatment in XX fish from 5 days after hatching (dah) to 120dah. Tilapia Pgr was abundantly expressed in the follicular cells surrounding oocytes at 30 and 90dah. Continuous RU486 treatment led to the blockage of oogenesis and masculinization of somatic cells in XX fish. Termination of RU486 treatment and maintenance in normal condition resulted in testicular differentiation, and estrogen compensation in RU486-treated XX fish successfully restored oogenesis. In RU486-treated XX fish, transcript levels of female dominant genes were significantly reduced, while male-biased genes were evidently augmented. Meanwhile, both germ cell mitotic and meiotic markers were substantially reduced. Consistently, estrogen production levels were significantly declined in RU486-treated XX fish. Taken together, our data further proved that DHP, possibly through Pgr, might be essential in the ovarian differentiation and estrogen production in fish. - Highlights: • DHP plays a critical role in early stage oogenesis of XX tilapia. • Blockage of DHP actions by RU486 treatment led to masculinization and/or sex reversal in XX tilapia. • Both DHP and estrogen are indispensable for ovarian differentiation.

    SRY, a sex-determining gene, induces testis development in chromosomally female (XX) individuals. However, mouse XX Sertoli cells carrying Sry (XX/Sry Sertoli cells) are incapable of fully supporting germ cell development, even when the karyotype of the germ cells is XY. While it has therefore been assumed that XX/Sry Sertoli cells are not functionally equivalent to XY Sertoli cells, it has remained unclear which specific functions are affected. To elucidate the functional difference, we compared the gene expression of XY and XX/Sry Sertoli cells. Lactate and cholesterol metabolisms, essential for nursing the developing germ cells, were down-regulated in XX/Sry cells, which appears to be caused at least in part by the differential expression of histone modification enzymes SMCX/SMCY (H3K4me3 demethylase) and UTX/UTY (H3K27me3 demethylase) encoded by the sex chromosomes. We suggest that down-regulation of lactate and cholesterol metabolism that may be due to altered epigenetic modification affects the nursing functions of XX/Sry Sertoli cells. PMID:28150810

  7. XX/XY System of Sex Determination in the Geophilomorph Centipede Strigamia maritima.

    Directory of Open Access Journals (Sweden)

    Jack E Green

    Full Text Available We show that the geophilomorph centipede Strigamia maritima possesses an XX/XY system of sex chromosomes, with males being the heterogametic sex. This is, to our knowledge, the first report of sex chromosomes in any geophilomorph centipede. Using the recently assembled Strigamia genome sequence, we identified a set of scaffolds differentially represented in male and female DNA sequence. Using quantitative real-time PCR, we confirmed that three candidate X chromosome-derived scaffolds are present at approximately twice the copy number in females as in males. Furthermore, we confirmed that six candidate Y chromosome-derived scaffolds contain male-specific sequences. Finally, using this molecular information, we designed an X chromosome-specific DNA probe and performed fluorescent in situ hybridization against mitotic and meiotic chromosome spreads to identify the Strigamia XY sex-chromosome pair cytologically. We found that the X and Y chromosomes are recognizably different in size during the early pachytene stage of meiosis, and exhibit incomplete and delayed pairing.

    Full Text Available Hace aproximadamente dos meses que Javier Cercas visitó el centro donde trabajo para charlar con los estudiantes sobre literatura. A lo largo de su intervención, tras ser preguntado por sus preferencias en cuanto a autores extremeños se refiere, vino a decir, o así lo intuí yo, que en realidad no existe una literatura extremeña per se, «aquella que se escribe en Extremadura o por extremeños» (Sáez, Lama, 2003. Esta reflexión trajo a mi memoria un artículo que leí no hace mucho tiempo y en cuyas líneas se pone en tela de juicio la idea de un dialecto extremeño, sin que ello suponga una falta de interés por el estudio de las distintas hablas que se dan en la ya mencionada región. Generalizando podemos decir que el extremeño no se escribe, y cuando así sucede, reproduce con palabras el plano fonético. Es decir, se intenta escribir como se habla. A lo largo de los primeros compases del siglo XX, autores de la región, entre los que destacan Luis Chamizo y Gabriel y Galán, plasmaron en sus escritos ese dialecto castúo tan particular.

    The population pharmacokinetics of ticagrelor and its active metabolite AR-C124910XX were characterized following ticagrelor 60 mg or 90 mg twice daily oral long-term treatment in 4,426 patients with a history of myocardial infarction. The ticagrelor and AR-C124910XX plasma concentration-time data were described by one-compartment models with first-order absorption or metabolite formation and elimination. Systemic exposure to ticagrelor and AR-C124910XX were stable over time. Ticagrelor apparent clearance (CL/F) was 17 L/h for the 60-mg and 15.4 L/h for the 90-mg dose. The CL/F of AR-C124910XX was 11.1 L/h for the 60-mg and 9.95 L/h for the 90-mg dose. Both ticagrelor and AR-C124910XX CL/F were independently influenced by body weight, sex, age, smoking, and Japanese ethnicity. Female sex and age > 75 years were the only categorical covariates, having more than 20% effect on AR-C124910XX CL/F. Ticagrelor CL/F was 6% higher and 11% lower, whereas AR-C124910XX CL/F was 26% higher and 34% lower for patients weighing 110 and 50 kg, respectively, compared with an 83 kg patient. The small differences in exposure to both ticagrelor and AR-C124910XX between demographic subgroups were in accordance with the consistent efficacy and safety outcomes observed across the population. The results were similar to those observed previously in patients with acute coronary syndromes.

  14. The Caenorhabditis Elegans Gene Sdc-2 Controls Sex Determination and Dosage Compensation in Xx Animals

    Science.gov (United States)

    Nusbaum, C.; Meyer, B. J.

    1989-01-01

    We have identified a new X-linked gene, sdc-2, that controls the hermaphrodite (XX) modes of both sex determination and X chromosome dosage compensation in Caenorhabditis elegans. Mutations in sdc-2 cause phenotypes that appear to result from a shift of both the sex determination and dosage compensation processes in XX animals to the XO modes of expression. Twenty-eight independent sdc-2 mutations have no apparent effect in XO animals, but cause two distinct phenotypes in XX animals: masculinization, reflecting a defect in sex determination, and lethality or dumpiness, reflecting a disruption in dosage compensation. The dosage compensation defect can be demonstrated directly by showing that sdc-2 mutations cause elevated levels of several X-linked transcripts in XX but not XO animals. While the masculinization is blocked by mutations in sex determining genes required for male development (her-1 and fem-3), the lethality, dumpiness and overexpression of X-linked genes are not, indicating that the effect of sdc-2 mutations on sex determination and dosage compensation are ultimately implemented by two independent pathways. We propose a model in which sdc-2 is involved in the coordinate control of both sex determination and dosage compensation in XX animals and acts in the regulatory hierarchy at a step prior to the divergence of the two pathways.

    Differentiation of the bipotential gonad into testis is initiated by the Y chromosome-linked gene SRY (Sex-determining Region Y) through upregulation of its autosomal direct target gene SOX9 (Sry-related HMG box-containing gene 9). Sequence and chromosome homology studies have shown that SRY most probably evolved from SOX3, which in humans is located at Xq27.1. Mutations causing SOX3 loss-of-function do not affect the sex determination in mice or humans. However, transgenic mouse studies have shown that ectopic expression of Sox3 in the bipotential gonad results in upregulation of Sox9, resulting in testicular induction and XX male sex reversal. However, the mechanism by which these rearrangements cause sex reversal and the frequency with which they are associated with disorders of sex development remains unclear. Rearrangements of the SOX3 locus were identified recently in three cases of human XX male sex reversal. We report on a case of XX male sex reversal associated with a novel de novo duplication of the SOX3 gene. These data provide additional evidence that SOX3 gain-of-function in the XX bipotential gonad causes XX male sex reversal and further support the hypothesis that SOX3 is the evolutionary antecedent of SRY.

    2012-01-01

    Full Text Available Aim: To evaluate the clinical profile and management of 46 XX Congenital Adrenal Hyperplasia (CAH patients presenting with severe virilization and assigned a male gender. Materials and Methods: Of 173 children diagnosed with CAH at the Pediatric Intersex Clinic since 1980, seven children with CAH presented late with severe virilization and were reared as males. All of them were assigned the male sex with removal of the female adnexa. Six were treated with male genitoplasty. Appropriate hormonal supplementation was offered after puberty. Results: The mean age at presentation was 14.2 years (7 - 21. Six patients had presented after puberty, only one at seven years of age. Staged male genitoplasty comprising of chordee correction, male urethroplasty, and bilateral testicular prosthesis was performed. The female adnexa (uterus, ovaries, most of the upper vagina, and the fallopian tubes were removed. The mental makeup was masculine in six and bigender in one. Bilateral mastectomy was performed at puberty in all. Hormonal treatment comprised of glucocorticoids and testosterone. Six patients were comfortable with the outcome of the masculinizing genitoplasty. One had a short-sized phallus. One had repeated attacks of urinary tract infection arising from the retained lower vaginal pouch. Social adjustments were good in all, except in one who had a bigender mental makeup. Conclusion: CAH patients with severe virilization presenting late and reared as males are extremely rare. However, the assigned gender can be retained adequately as males, meeting the socioeconomic compulsions of the society. The results are satisfactory following appropriate surgical procedures and hormonal supplementation.

  19. Dynamics Of Social Legislation In Russian Empire In The Beginnings Of XX Century

    Full Text Available In the present article regulations adopted in the Russian Empire at the beginning of the XX century and defining direction of social legislation development are considered. Norms that regulated state contempt of the lower ranks and members of their families in Russia, and also laws on social insurance are considered. There was no complete system of state social contempt in the Russian Empire. Help to needed was usually provided by numerous non-state charitable structures and societies, thus many of them were under patronage of the imperial family members. This help was provided, first - selectively, second - its size usually was very small. In general, specifics of the legislative ensuring of social support were defined by the features of development of entire legal system of the Russian Empire during this period, including, dynamics of normative legal acts adoption. Author draws a conclusion about preservation of the class character in the organization of the state contempt in the Russian Empire. In 1912 in the Russian Empire acts that directed creation of the system of social insurance for social protection of persons, victims of injuries and mutilations at the factory enterprises, and members of their family’s were adopted. Adoption of the acts regulating social insurance can be considered as a positive step in development of the social orientated legislation. But these acts were far from perfect, and first of all because their action extended on smaller part of the country's working population. According to the author, adoption of the legislation on social insurance became a basic step on the way of modern forms of the organization of the social help creation.

  20. High temperature increases the masculinization rate of the all-female (XX rainbow trout "Mal" population.

    Directory of Open Access Journals (Sweden)

    Karina Valdivia

    Full Text Available Salmonids are generally considered to have a robust genetic sex determination system with a simple male heterogamety (XX/XY. However, spontaneous masculinization of XX females has been found in a rainbow trout population of gynogenetic doubled haploid individuals. The analysis of this masculinization phenotype transmission supported the hypothesis of the involvement of a recessive mutation (termed mal. As temperature effect on sex differentiation has been reported in some salmonid species, in this study we investigated in detail the potential implication of temperature on masculinization in this XX mal-carrying population. Seven families issued from XX mal-carrying parents were exposed from the time of hatching to different rearing water temperatures ((8, 12 and 18°C, and the resulting sex-ratios were confirmed by histological analysis of both gonads. Our results demonstrate that masculinization rates are strongly increased (up to nearly two fold at the highest temperature treatment (18°C. Interestingly, we also found clear differences between temperatures on the masculinization of the left versus the right gonads with the right gonad consistently more often masculinized than the left one at lower temperatures (8 and 12°C. However, the masculinization rate is also strongly dependent on the genetic background of the XX mal-carrying families. Thus, masculinization in XX mal-carrying rainbow trout is potentially triggered by an interaction between the temperature treatment and a complex genetic background potentially involving some part of the genetic sex differentiation regulatory cascade along with some minor sex-influencing loci. These results indicate that despite its rather strict genetic sex determinism system, rainbow trout sex differentiation can be modulated by temperature, as described in many other fish species.

    The molecular mechanisms underlying sex differences in dyslipidemia are poorly understood. We aimed to distinguish genetic and hormonal regulators of sex differences in plasma lipid levels. We assessed the role of gonadal hormones and sex chromosome complement on lipid levels using the four core genotypes mouse model (XX females, XX males, XY females, and XY males). In gonadally intact mice fed a chow diet, lipid levels were influenced by both male-female gonadal sex and XX-XY chromosome complement. Gonadectomy of adult mice revealed that the male-female differences are dependent on acute effects of gonadal hormones. In both intact and gonadectomized animals, XX mice had higher HDL cholesterol (HDL-C) levels than XY mice, regardless of male-female sex. Feeding a cholesterol-enriched diet produced distinct patterns of sex differences in lipid levels compared with a chow diet, revealing the interaction of gonadal and chromosomal sex with diet. Notably, under all dietary and gonadal conditions, HDL-C levels were higher in mice with 2 X chromosomes compared with mice with an X and Y chromosome. By generating mice with XX, XY, and XXY chromosome complements, we determined that the presence of 2 X chromosomes, and not the absence of the Y chromosome, influences HDL-C concentration. We demonstrate that having 2 X chromosomes versus an X and Y chromosome complement drives sex differences in HDL-C. It is conceivable that increased expression of genes escaping X-inactivation in XX mice regulates downstream processes to establish sexual dimorphism in plasma lipid levels. © 2015 American Heart Association, Inc.

    All-female lines of fish are created by crossing sex reversed (XX genotype) males with normal females. All-female lines avoid the deleterious phenotypic effects that are typical of precocious maturation in males. To determine whether all-female and mixed sex populations of rainbow trout (Oncorhynchus mykiss) differ in performance, we compared the growth and gene expression profiles in progeny groups produced by crossing a XX male and a XY male to the same five females. Body weight and length were measured in the resulting all-female (XX) and mixed sex (XX/XY) offspring groups. Microarray experiments with liver and white muscle were used to determine if the gene expression profiles of large and small XX offspring differ from those in large and small XX/XY offspring. We detected no significant differences in body length and weight between offspring groups but XX offspring were significantly less variable in the value of these traits. A large number of upregulated genes were shared between the large XX and large XX/XY offspring; the small XX and small XX/XY offspring also shared similar expression profiles. No GO category differences were seen in the liver or between the large XX and large XX/XY offspring in the muscle. The greatest differences between the small XX and small XX/XY offspring were in the genes assigned to the "small molecule metabolic process" and "cellular metabolic process" GO level 3 categories. Similarly, genes within these categories as well as the category "macromolecule metabolic process" were more highly expressed in small compared to large XX fish.

    Forty-six XX disorder of sex development is an uncommon medical condition observed at times during the evaluation of a man's fertility. The following is a case series and literature review of phenotypically normal men diagnosed with this karyotype. Our goal is to comprehend the patients' clinical presentation as well as their laboratory results aiming to explore options available for their management. A formal literature review through PubMed and MEDLINE databases was performed using "46 XX man" as a word search. A total of 55 patients, including those conveyed in this article were diagnosed with a 46 XX karyotype during their fertility evaluation. The patients' mean age ± s.d. was 34 ± 10 years and their mean height ± s.d. was 166 ± 6.5 cm. Overall, they presented with hypergonadotropic hypogonadism. Sexual dysfunction, reduced hair distribution, and gynecomastia were reported in 20% (4/20), 25.8% (8/31), and 42% (13/31) of the patients, respectively. The SRY gene was detected in 36 (83.7%) and was absent in the remaining seven (16.3%) patients. We found that a multidisciplinary approach to management is preferred in 46 XX patients. Screening for remnants of the mullerian ducts and for malignant transformation in dysgenetic gonads is imperative. Hypogonadism should be addressed, while fertility options are in vitro fertilization with donor sperm or adoption.

    Highlights: • Pressure drop of NACA 0020 airfoil fin PCHE reduces strikingly in comparison with the zigzag PCHE. • Pressure drop of NACA 00XX airfoil fin PCHE decreases as airfoil thickness increases. • Heat transfer performance of NACA 00XX airfoil fin PCHE increases as airfoil thickness rises. • Comprehensive performance of NACA 00XX airfoil fin PCHE degrades as airfoil thickness increases. - Abstract: Printed circuit heat exchanger (PCHE) can be used in supercritical carbon dioxide (S-CO{sub 2}) Brayton cycle. The present study compares NACA 0020 airfoil fin PCHE with conventional zigzag PCHE by numerical analysis. Pressure drop of the former has a striking reduction while maintaining excellent heat transfer performance. Comparison on four NACA 00XX series airfoil fin PCHEs is performed to investigate the influence of airfoil profile on flow and heat transfer performance. With a fixed vertical pitch, heat transfer performance of NACA series airfoil fin PCHE increases as airfoil thickness increases. However, comprehensive performance, in which both flow and heat transfer are taken into account, degrades with increasing airfoil thickness. Among four NACA airfoil fin PCHEs presented in this paper, NACA 0010 airfoil fin PCHE demonstrates the best comprehensive performance.

    The agricultural pest Ceratitis capitata, also known as the Mediterranean fruit fly or Medfly, is a fruit crop pest of very high economic relevance in different continents. The strategy to separate Ceratitis males from females (sexing) in mass rearing facilities is a useful step before the sterilization and release of male-only flies in Sterile Insect Technique control programs (SIT). The identification of genes having early embryonic male-specific expression, including Y-linked genes, such as the Maleness factor, could help to design novel and improved methods of sexing in combination with transgenesis, aiming to confer conditional female-specific lethality or female-to-male sexual reversal. We used a combination of Suppression Subtractive Hybrydization (SSH), Mirror Orientation Selection (MOS) anddifferential screening hybridization (DSH) techniques to approach the problem of isolating corresponding mRNAs expressed in XX/XY embryos versus XX-only embryos during a narrow developmental window (8-10 hours after egg laying, AEL ). Here we describe a novel strategy we have conceived to obtain relatively large amounts of XX-only embryos staged at 8-10 h AEL and so to extract few micrograms of polyA+ required to apply the complex technical procedure. The combination of these 3 techniques led to the identification of a Y-linked putative gene, CcGm2, sharing high sequence identity to a paralogous gene, CcGm1, localized either on an autosome or on the X chromosome. We propose that CcGm2 is a first interesting putative Y-linked gene which could play a role in sex determination. The function exterted by this gene should be investigated by novel genetic tools, such as CRISPR-CAS9, which will permit to target only the Y-linked paralogue, avoiding to interfere with the autosomal or X-linked paralogue function.

    Full Text Available 2D array of ionization chambers can be used for both absolute and relative dose verification of patient-specific intensity-modulated radiotherapy (IMRT quality assurance. After an analysis of the dose linearity and spatial resolution of this 2D array (I′mRT MatriXX, the signal sampling time of 200 ms was selected for data acquisition. Multiple-sequence acquisitions at the nearest 4 positions with the shift of half of the distance between the centers of two adjacent ion chambers increase the spatial resolution up to four times when used with this I′mRT MatriXX. IMRT verification of head-and-neck case, which requires a large area for dosimetric verification, can be done with limited size of 24x24 cm 2 , depending on the user requirements. It is found that the convolution method can also be used to improve the IMRT dose verification with the same parameters of the passing criteria significantly, viz., up to 99.87% agreement, by smoothening the treatment planning system profile.

    A 2-year-old boy was found to have a 47,XXX karyotype. Restriction-fragment-length-polymorphism analysis showed that, of his three X chromosomes, one is of paternal and two are of maternal origin. The results of Y-DNA hybridization were reminiscent of those in XX males in two respects. First, hybridization to Southern transfers revealed the presence in this XXX male of sequences derived from the Y-chromosomal short arm. Second, in situ hybridization showed that this Y DNA was located on the tip of the X-chromosomal short arm. We conclude that this XXX male resulted from the coincidence of X-X nondisjunction during maternal meiosis and aberrant X-Y interchange either during or prior to paternal meiosis.

    The authors describe the whole-body chimerism in a newborn infant with small phallus, pseudo-vaginal perineal hypospadias, and a bifid scrotum containing gonads. The human testis determining factor gene (SRY) was detected by PCR amplification. GTG-banding chromosome analysis in peripheral blood lymphocytes and cultured fibroblasts derived from right cubital skin showed a 46,XX/47,XY, +21 karyotype. Their ratios in each cell line were 294:5 and 178:7, respectively. QFQ-banding chromosome analysis documented 3 heteromorphic satellites on trisomic chromsomes 21 in the 47,XY,+21 cell line and a homozygous satellite pattern in the 46,XX cell line. Heteromorphic patterns of chromsomes 4, 13, 14, and 22 were also different between the two cell lines. To our knowledge, such disomy/trisomy chimeras have not been described previously. 10 refs., 3 figs.

    We report a case of discordant phenotypic sex in monozygotic twins mosaic 47,XXY/46,XX: monozygotic heterokaryotypic twins. The twins presented with cognitive and comprehension delay, behavioural and language disorders, all symptoms frequently reported in Klinefelter syndrome. Molecular zygosity analysis with several markers confirmed that the twins are in effect monozygotic (MZ). Array comparative genomic hybridization found no evidence for the implication of copy number variation in the phenotypes. Ultrasound scans of the reproductive organs revealed no abnormalities. Endocrine tests showed a low testosterone level in Twin 1 (male phenotype) and a low gonadotrophin level in Twin 2 (female phenotype) which, combined with the results from ultrasound examination, provided useful information for potentially predicting the future fertility potential of the twins. Blood karyotypes revealed the presence of a normal 46,XX cell line and an aneuploïd 47,XXY cell line in both patients. Examination of the chromosome constitutions of various tissues such as blood, buccal smear and urinary sediment not surprisingly showed different proportions for the 46,XX and 47,XXY cell lines, which most likely explains the discordant phenotypic sex and mild Klinefelter features. The most plausible underlying biological mechanism is a post-zygotic loss of the Y chromosome in an initially 47,XXY zygote. This would result in an embryo with both 46,XX and 47,XXY cells lines which could subsequently divide into two monozygotic embryos through a twinning process. The two cell lines would then be distributed differently between tissues which could result in phenotypic discordances in the twins. These observations emphasize the importance of regular paediatric evaluations to determine the optimal timing for fertility preservation measures and to detect new Klinefelter features which could appear throughout childhood in the two subjects. © The Author 2014.

    Full Text Available Abstract Background Approximately 30 sex-chromosome discordant chimera cases have been reported to date, of which only four cases carried trisomy 21. Here, we present an additional case, an aborted fetus with a karyotype of 47,XX, +21/46,XY. Case presentation Autopsy demonstrated that this fetus was normally developed and had male genitalia. Major characteristics of Down syndrome were not observed except an enlarged gap between the first and second toes. Karyotyping of tissues cultured from the fetus revealed the same chimeric chromosomal composition detected in the amniotic fluid but with a different ratio of [47,XX,+21] to [46,XY]. Further short tandem repeat analysis indicated a double paternal contribution and single maternal contribution to the fetus, with the additional chromosome 21 in the [47,XX,+21] cell lineage originating from the paternal side. Conclusion We thus propose that this chimeric fetus was formed via the dispermic fertilization of a parthenogenetic ovum with one (Y sperm and one (X,+21 sperm.

    Sexual development in mammals is based on a complicated and delicate network of genes and hormones that have to collaborate in a precise manner. The dark side of this pathway is represented by pathological conditions, wherein sexual development does not occur properly either in the XX and the XY background. Among them a conundrum is represented by the XX individuals with at least a partial testis differentiation even in absence of SRY. This particular condition is present in various mammals including the dog. Seven dogs characterized by XX karyotype, absence of SRY gene, and testicular tissue development were analysed by Array-CGH. In two cases the array-CGH analysis detected an interstitial heterozygous duplication of chromosome 9. The duplication contained the SOX9 coding region. In this work we provide for the first time a causative mutation for the XXSR condition in the dog. Moreover this report supports the idea that the dog represents a good animal model for the study of XXSR condition caused by abnormalities in the SOX9 locus.

    The aim of the study was to examine the association between the ACTN3 R577X polymorphism in canoe sprint athletes (canoe and kayak paddlers) and their results at 200- or 1000-m distance. Eighty-six European white male athletes divided into 2 groups-successful, who were outstanding at national championships, and nonsuccessful in these competitions-and 354 nonathletic controls were included in this study. The R577X polymorphism of ACTN3 was typed using PCR-RFLP. ACTN3 genotype distribution among all tested athletes and controls was in Hardy-Weinberg equilibrium. The odds ratio (OR) for successful 1000-m athletes harboring the XX genotype compared with sedentary controls was 2.95 (95% confidence interval [CI]: 1.37-6.35), but the OR for nonsuccessful 200-m athletes having the XX genotype compared with controls was 2.64 (95% CI: 1.30-5.36). These results suggest that factors associated with the ACTN3 XX genotype in canoe and kayak paddlers might provide some competitive advantage in performance at 1000 m, but it seems to limit at 200 m. Further studies aimed at development of training strategies based on genetic factors are needed.

    Full Text Available Triploidy is common in human pregnancies. It is detected in 1 to 2% of clinically recognized pregnancies and in approximately 15 to 20% of spontaneous abortions produced by chromosome anomalies. We report a premature liveborn girl (30 weeks of gestation with microcephaly, facial dysmorphism and skeletal abnormalities who died at one day of age due to respiratory failure. The placenta showed partial hydatiform mole. Autopsy revealed no internal malformations. Cytogenetic analysis of 100 metaphases obtained from renal tissue culture revealed a 68,XX[73]/69,XXX[27] karyotype. To our knowledge this is the first report in the literature of 68,XX[73]/69,XXX[27] mosaicism in a liveborn infant.A triploidia é uma anomalia cromossômica comum encontrada em 1 a 2% das gestações clinicamente reconhecidas e em cerca de 15 a 20% dos abortos espontâneos de causa cromossômica. Em aproximadamente 5% dos casos, uma aneuploidia pode estar também associada (Boué et al., 1985. Descrevemos um recém-nascido do sexo feminino, prematuro (30 semanas de idade gestacional, com microcefalia, dismorfias faciais e alterações de membros, que foi a óbito com 1 dia de vida por insuficiência respiratória. O exame anátomo-patológico da placenta revelou alterações compatíveis com degeneração molar. A necrópsia da criança não evidenciou malformações internas. A análise citogenética de 100 metáfases, obtidas a partir de cultura de tecido renal, evidenciou cariótipo 68,XX[73]/69,XXX[27]. Apenas 9 casos de triploidia 68,XX foram descritos anteriormente, sendo 7 em abortos, 1 em feto de 21 semanas e 1 em recém-nascido a termo. Consideramos que este estudo seja o primeiro da literatura relatando a ocorrência de mosaicismo 69,XXX/68,XX em um recém-nascido vivo. Os autores discutem os achados clínicos e os possíveis mecanismos envolvidos nesta aberração cromossômica.

    Steroidogenic factor 1 (NR5A1, SF-1, Ad4BP) is a transcriptional regulator of genes involved in adrenal and gonadal development and function. Mutations in NR5A1 have been among the most frequently identified genetic causes of gonadal development disorders and are associated with a wide phenotypic spectrum. In 46,XY individuals, NR5A1-related phenotypes may range from disorders of sex development (DSD) to oligo/azoospermia, and in 46,XX individuals, from 46,XX ovotesticular and testicular DSD to primary ovarian insufficiency (POI). The most common 46,XY phenotype is atypical or female external genitalia with clitoromegaly, palpable gonads, and absence of Müllerian derivatives. Notably, an undervirilized external genitalia is frequently seen at birth, while spontaneous virilization may occur later, at puberty. In 46,XX individuals, NR5A1 mutations are a rare genetic cause of POI, manifesting as primary or secondary amenorrhea, infertility, hypoestrogenism, and elevated gonadotropin levels. Mothers and sisters of 46,XY DSD patients carrying heterozygous NR5A1 mutations may develop POI, and therefore require appropriate counseling. Moreover, the recurrent heterozygous p.Arg92Trp NR5A1 mutation is associated with variable degrees of testis development in 46,XX patients. A clear genotype-phenotype correlation is not seen in patients bearing NR5A1 mutations, suggesting that genetic modifiers, such as pathogenic variants in other testis/ovarian-determining genes, may contribute to the phenotypic expression. Here, we review the published literature on NR5A1-related disease, and discuss our findings at a single tertiary center in Brazil, including ten novel NR5A1 mutations identified in 46,XY DSD patients. The ever-expanding phenotypic range associated with NR5A1 variants in XY and XX individuals confirms its pivotal role in reproductive biology, and should alert clinicians to the possibility of NR5A1 defects in a variety of phenotypes presenting with gonadal dysfunction

    This work aimed at giving a deeper insight into peculiar cases of intersexuality occurring in dogs and known as XX true hermaphrodism due to the existence of both testicular and ovarian tissue in one or both gonads in the presence of an XX chromosome constitution. Clinical, histological and genetic approaches were used in the study of an 8-month-old Cocker Spaniel dog and a 3-year-old mixed-breed Pitbull, both showing a female phenotype, clitoromegaly and male behavior. A normal female karyotype (2n = 78,XX) was noticed, and polymerase chain reaction failed to detect SRY in genomic DNA obtained from peripheral blood lymphocytes of both dogs. The reproductive tract was removed by standard ovariohysterectomy and processed for histology. Thereafter, a normal female phenotype was reconstructed by vaginoplasty. Histological examination revealed bilateral ovotestis in both cases: the gonads showed immature testicular parenchyma containing seminiferous tubules, Sertoli and Leydig cells, but no signs of spermatogenesis, together with differently developed ovarian follicles containing oocytes. In the ovotestes, steroidogenesis was detected by P450c17-immunoreactivity in Leydig cells as well as in theca cells, whereas no MIS-immunoreactivity was shown by the Sertoli cells. Genital tracts of Wolffian and Müllerian origin co-existed in both subjects. Both dogs belong to the very rare cases in which testicular tissue develops in the absence of the key gene, SRY. Up to date very few genetic events have been associated with this abnormal sexual differentiation: SOX9 over-expression and RSPO1 mutation. Nevertheless, neither of them has been found in these dogs.

    Full Text Available En este trabajo se logró conocer los criterios de clasificación empleados para definir a la población con discapacidad en los registros censales del siglo XX en Costa Rica y, por consiguiente, una aproximación a las formulaciones conceptuales para referirse al grupo en estudio. Además, se caracterizó a ese segmento poblacional a partir de diferentes variables: sexo, edad, estado civil y distribución geográfica. También se abordaron otros aspectos como fueron: alfabetismo, nivel de educación, ocupación, jefatura de hogar y vivienda. Entre los hallazgos más destacables se encuentra la permanencia, en los registros censales del siglo XX, de un concepto de discapacidad basado en la deficiencia, lo que definió los criterios de clasificación para esa población en esas fuentes. Asimismo se constató, por una parte, la asociación entre discapacidad e inequidad en esa centuria y, por la otra, la fragilidad de los vínculos de parentesco en ese grupo poblacional con respecto al conjunto de hogares de Costa Rica a fines de ese siglo. Las fuentes empleadas en esta investigación fueron los censos de población de Costa Rica del siglo XX. En el procedimiento con los datos, se llevó a cabo un análisis descriptivo de distribución de frecuencias.

    Full Text Available The article considers the question of forms of wages paid to workers in the mining industry of Siberia in the late XIX – early XX centuries. Of the two main forms of labor compensation – hourly rate and piecework pay, the latter was more corresponding to the spirit of capitalism, and it was most widespread in the mining enterprises of Siberia. The piecework pay was also the main instrument for intensifying labor productivity. This episode in the history of labor is studied on the basis of paperwork materials of mining companies and reporting documents of the mining inspectorate.

    Full Text Available CCD time series photometry was performed for two Oosterhoff type II± field RR Lyrae stars, SV Eri and XX And, to construct light curves in B and V bands. The maximum light times from our observations were combined with those in the literature to construct phase shift diagrams, from which we determined the period change rates β. We obtained large positive period change rates for these stars, which are expected from current evolutionary models if these stars are evolving rapidly from blue to red toward the end of core helium burning phase.

    We studied the trace distance, the Hellinger distance, and the Bures distance geometric quantum discords (GQDs) for a two-spin Heisenberg XX chain with the Dzyaloshinsky–Moriya (DM) interaction and the external magnetic fields. We found that considerable enhancement of the GQDs can be achieved by introducing the DM interaction, and their maxima were obtained when the strength of the DM interaction approaches infinity. The external magnetic fields and the increase of the temperature can also enhance the GQDs to some extent during certain specific parameter regions.

  19. Spot evolution on the red giant star XX Triangulum. A starspot-decay analysis based on time-series Doppler imaging

    Context. Solar spots appear to decay linearly proportional to their size. The decay rate of solar spots is directly related to magnetic diffusivity, which itself is a key quantity for the length of a magnetic-activity cycle. Is a linear spot decay also seen on other stars, and is this in agreement with the large range of solar and stellar activity cycle lengths? Aims: We investigate the evolution of starspots on the rapidly-rotating (Prot≈24 d) K0 giant XX Tri, using consecutive time-series Doppler images. Our aim is to obtain a well-sampled movie of the stellar surface over many years, and thereby detect and quantify a starspot decay law for further comparison with the Sun. Methods: We obtained continuous high-resolution and phase-resolved spectroscopy with the 1.2-m robotic STELLA telescope on Tenerife over six years, and these observations are ongoing. For each observing season, we obtained between 5 to 7 independent Doppler images, one per stellar rotation, making up a total of 36 maps. All images were reconstructed with our line-profile inversion code iMap. A wavelet analysis was implemented for denoising the line profiles. To quantify starspot area decay and growth, we match the observed images with simplified spot models based on a Monte Carlo approach. Results: It is shown that the surface of XX Tri is covered with large high-latitude and even polar spots and with occasional small equatorial spots. Just over the course of six years, we see a systematically changing spot distribution with various timescales and morphology, such as spot fragmentation and spot merging as well as spot decay and formation. An average linear decay of D = -0.022 ± 0.002 SH/day is inferred. We found evidence of an active longitude in phase toward the (unseen) companion star. Furthermore, we detect a weak solar-like differential rotation with a surface shear of α = 0.016 ± 0.003. From the decay rate, we determine a turbulent diffusivity of ηT = (6.3 ± 0.5) × 1014 cm2/s and

  20. La persistencia del surrealismo en la arquitectura religiosa española del siglo XX

    2011-07-01

    Full Text Available Este artículo trata de averiguar si el surrealismo —no entendido tanto como estilo artístico, sino como manera compleja de entender la vida— puede postularse como hilo conductor de la arquitectura religiosa del siglo XX en España. Aunque es posible leer la arquitectura católica moderna como un intento de integrar el dogma con las aspiraciones del llamado espíritu de los tiempos, la pérdida de peso que supuso este planteamiento para la arquitectura todavía no se ha esclarecido lo suficiente. La pervivencia de las tradiciones, el diálogo entre la teología y el arte o la crisis de identidad católica tras el Concilio Vaticano II son facetas del intenso —y a veces obsesivo— debate que se desarrolló en España durante el siglo XX. A la postre, se constata que la perenne vena surrealista que subyace en todo lo español impregna también la arquitectura sacra y dificulta su correcta lectura. Se evidencia, finalmente, que la arquitectura religiosa es susceptible de miradas transversales sobre el hecho construido y que abre el campo a nuevas interpretaciones.

    Full Text Available Over the centuries in Mexico, such as in many other countries, the traditional role of women has been that of being a housewife and a mother; therefore, they had no access to education. Young women from rich families studied art and music, mostly as entertainment. Music wasn’t considered a profession, there were no music schools, and some academies or private teachers filled that void. In this context, a particular merit is made for those women who took the decision to participate in the social, cultural and political life of the society they belonged to. Their contribution to education, spreading of the musical arts, and specially pianism in the northeast region hasn’t been appreciated enough, despite the great effort, enthusiasm and devotion they demonstrated. This article takes an approach on the role of women within the piano studies during the XX century in the northeast of Mexico from the following questions: Who were the women who made the educational work in the musical and pianistic field in the northeast of Mexico during the XX century? Who were the women who made piano their profession and turned out of a great importance for the dissemination of piano arts and the pianistic repertoire in the region of reference?

    46,XX male sex reversal occurs in approximately 1: 20 000 live births and is most commonly caused by interchromosomal translocations of the Y-linked sex-determining gene, SRY. Rearrangements of the closely related SOX3 gene on the X chromosome are also associated with 46,XX male sex reversal. It has been hypothesized that sex reversal in the latter is caused by ectopic expression of SOX3 in the developing urogenital ridge where it triggers male development by acting as an analog of SRY. However, altered regulation of SOX3 in individuals with XX male sex reversal has not been demonstrated. Here we report a boy with SRY-negative XX male sex reversal who was diagnosed at birth with a small phallus, mixed gonads, and borderline-normal T. Molecular characterization of the affected individual was performed using array comparative genomic hybridization, fluorescent in situ hybridization of metaphase chromosomes, whole-genome sequencing, and RT-PCR expression analysis of lymphoblast cell lines. The affected male carries ∼774-kb insertion translocation from chromosome 1 into a human-specific palindromic sequence 82 kb distal to SOX3. Importantly, robust SOX3 expression was identified in cells derived from the affected individual but not from control XX or XY cells, indicating that the translocation has a direct effect on SOX3 regulation. This is the first demonstration of altered SOX3 expression in an individual with XX male sex reversal and suggests that SOX3 can substitute for SRY to initiate male development in humans.

    Purpose: The quality assurance (QA) procedure has to check the most relevant beam parameters to ensure the delivery of the correct dose to patients. Film dosimetry, which is commonly used for scanned ion beam QA, does not provide immediate results. The purpose of this work is to answer whether, for scanned ion beam therapy, film dosimetry can be replaced with the 2D MatriXX detector as a real-time tool. Methods: MatriXX, equipped with 32×32 parallel plate ion-chambers, is a commercial device intended for pre-treatment verification of conventional radiation therapy.The MatriXX, placed at the isocenter, and GAFCHROMIC films, positioned on the MatriXX entrance, were exposed to 131.44 MeV proton and 221.45 MeV/u Carbon-ion beams.The OmniPro-I’mRT software, applied for the data taking of MatriXX, gives the possibility of acquiring consecutive snapshots. Using the NI LabVIEW, the data from snapshots were logged as text files for further analysis. Radiochromic films were scanned with EPSON scanner and analyzed using software programs developed in-house for comparative purposes. Results: The field dose uniformity, flatness, beam position and beam width were investigated. The field flatness for the region covering 6×6 cm{sup 2} square field was found to be better than 2%. The relative standard deviations, expected to be constant over 2×2, 4×4 and 6×6 pixels from MatriXX measurement gives a uniformity of 1.5% in good agreement with the film results.The beam center position is determined with a resolution better than 200 µm for Carbon and less than 100 µm for proton beam.The FWHM determination for a beam wider than 10 mm is satisfactory, whilst for smaller beams the determination is uncertain. Conclusion: Precise beam position and fast 2D dose distribution can be determined in real-time using MatriXX detector. The results show that MatriXX is quick and accurate enough to be used in charged-particle therapy QA.

    Full Text Available RESUMENEn este trabajo se logró conocer los criterios de clasificación empleados para definir a la población con discapacidad en los registros censales del siglo XX en Costa Rica y, por consiguiente, una aproximación a las formulaciones conceptuales para referirse al grupo en estudio. Además, se caracterizó a ese segmento poblacional a partir de diferentes variables: sexo, edad, estado civil y distribución geográfica. También se abordaron otros aspectos como fueron: alfabetismo, nivel de educación, ocupación, jefatura de hogar y vivienda. Entre los hallazgos más destacables se encuentra la permanencia, en los registros censales del siglo XX, de un concepto de discapacidad basado en la deficiencia, lo que definió los criterios de clasificación para esa población en esas fuentes. Asimismo se constató, por una parte, la asociación entre discapacidad e inequidad en esa centuria y, por la otra, la fragilidad de los vínculos de parentesco en ese grupo poblacional con respecto al conjunto de hogares de Costa Rica a fines de ese siglo. Las fuentes empleadas en esta investigación fueron los censos de población de Costa Rica del siglo XX. En el procedimiento con los datos, se llevó a cabo un análisis descriptivo de distribución de frecuencias. ABSTRACTThis research discloses the classification criteria used to define the population with disability in the twentieth century census records in Costa Rica and therefore gives an approximation of the conceptual formulations needed to refer to the examined group. Additionally, a segment of the population has been characterized by sex, age, marital status and geographical distribution. Other aspects like literacy rate, education level, occupation, head of household and housing were also dealt with. The disability concept based on deficiency, which defined the classification criteria for the population in those data sources, is among the most significant findings of this research. Furthermore

  13. 46, XX true hermaphroditism associated with a terminal deletion of the short arm of the X chromosome

    Testes are determined by the activity of the SRY gene product encoded by the Y chromosome. Mutations in SRY can lead to XY sex reversal (XY females) and the presence of the SRY gene in some XX individuals can lead either to complete (XX males) or incomplete (XX true hermaphrodites) sex reversal. Approximately 10% of XX true hermaphrodites contain a portion of the Y chromosome, including SRY, in their genome. The etiology of the remaining cases is unestablished but may be caused by mutations in other as yet unidentied sex determining genes downstream of SRY. Here we describe an SRY-negative true hermaphrodite with a 46,X,del(X)(p21.1-pter). The patient also presented with severe mental retardation, abnormal skin pigmentation and below average height. Histological examination of the gonad revealed bilateral ovotestis. We postulate that the Xp deletion has unmasked a recessive allele on the apparently normal X chromosome generating the intersex phenotype. This observation together with recent findings of certain XY females carrying duplications of Xp21.3 suggests that there may be a loci on Xp which acts as a switch in the testis/ovarian determination pathways.

    A 33-year-old woman was hospitalized for examination of edematous laryngopharynx. She was acromegalic. A pituitary adenoma with elevated serum levels of growth hormone (GH) and insulin-like growth factor-I (IGF-I) was detected, indicating acromegaly caused by GH-secreting pituitary adenoma. Multiple pigmented nevi were also noted without overt short stature and cubitus valgus. Chromosome analysis revealed that she had contracted Turner syndrome with 47,XXX/45,X/46,XX mosaicism. Transsphenoidal resection of the tumor decreased serum GH and IGF-I levels, but the edema was not improved. Both premature ovarian failure and hypertension appeared after surgery. This case may indicate the important relationships between GH/IGF-I and Turner syndrome.

    Progressive renal insufficiency, male pseudohermaphrotidism, and Wilms tumor are known as the triad of Drash syndrome. The renal involvement has been reported in association with Wilms tumor with or without pseudohermaphroditism. The nephropathy progresses rapidly, is unresponsive to steroids, and eventually requires dialysis. The case we report is a 46,XX phenotypic female child who had diffuse mesangial sclerosis (DMS) and developed Wilms tumor 3 years after initiating dialysis for end-stage renal disease (ESRD). Any child presenting with DMS should be considered at risk for development of Wilms tumor and should be investigated for the presence of XY gonadal dysgenesis. Once ESRD develops in such a child, prophylactic nephrectomy and possibly gonadectomy should be undertaken.

    In this work, we investigate the quantum-memory-assisted entropic uncertainty relation in a two-qubit Heisenberg XX model with inhomogeneous magnetic field. It has been found that larger coupling strength J between the two spin-chain qubits can effectively reduce the entropic uncertainty. Besides, we observe the mechanics of how the inhomogeneous field influences the uncertainty, and find out that when the inhomogeneous field parameter b1. Intriguingly, the entropic uncertainty can shrink to zero when the coupling coefficients are relatively large, while the entropic uncertainty only reduces to 1 with the increase of the homogeneous magnetic field. Additionally, we observe the purity of the state and Bell non-locality and obtain that the entropic uncertainty is anticorrelated with both the purity and Bell non-locality of the evolution state.

    The mount drive control is the key technique which mostly affects astronomical telescope's resolution and its speed. However, the ultra -lower speed and the giant moment of inertia make it very difficult to be controlled. In this paper, one segmented permanent-magnet synchronous motor (PMSM), 4m diameter, is suggested for the mount driving. A method is presented to drive the motor directly, which is based on TMS320F28XX and Insulated Gate Bipolar Transistor (IGBT) , also, HEIDENHAIN tape is used to detect the absolute position of the motor together with the Hall sensor. The segmented PMSM can work stable and the mount drive can realize nice tracking performance at ultra -lower speed with this drive system.

  10. Diverging conductance at the contact between random and pure quantum XX spin chains

    Chatelain, Christophe

    2017-11-01

    A model consisting of two quantum XX spin chains, one homogeneous and the second with random couplings drawn from a binary distribution, is considered. The two chains are coupled to two different non-local thermal baths and their dynamics is governed by a Lindblad equation. In the steady state, a current J is induced between the two chains by coupling them together by their edges and imposing different chemical potentials μ to the two baths. While a regime of linear characteristics J versus Δμ is observed in the absence of randomness, a gap opens as the disorder strength is increased. In the infinite-randomness limit, this behavior is related to the density of states of the localized states contributing to the current. The conductance is shown to diverge in this limit.

Como él, muchos otros pensamos que se puede aprender del pasado para construir el futuro; pero es importante precisar, desde ahora, que no se pretende mirar al pasado para construir modelos de imitación o réplica, y mucho menos para levantar ídolos sobre la premisa de que “todo tiempo pasado fue mejor”, como suelen afirmar algunos pesimistas.

    Background: In congenital adrenal hyperplasia (CAH) with ambiguous genitalia, assigning gender of rearing can be complex, especially If genitalia is highly virilized. Apart from karyotype, prenatal androgen exposure, patient's gender orientation, sociocultural, and parental influences play a role. The aim of this study was to assess gender dysphoria and psychosocial issues in patients of CAH raised as males and females. Materials and Methods: This is a cross-sectional study that includes patients (old and new) with CAH who were treated by us in the last 6 months. A semi-structured interview proforma was used to elicit history and psychosocial background of the patients. The clinical and biochemical details were noted. For psychological analysis, patients were screened for gender dysphoria using Parent Report Gender Identity Questionnaire for children Gender Identity/Gender Dysphoria Questionnaire for Adolescents and Adults. Results: We analyzed 22 46 XX CAH patients among which, 3 were reared as males and 19 as females. Among the 19 patients reared as females, 17 patients showed no gender dysphoria. Two patients revealed gender dysphoria as indicated by their marginally low scores on the gender dysphoria assessment. However, in view of current literature and the age groups of the patients, behavior of the 6-year-old patient can be best understood as being tomboyish. Gender dysphoria in the 22-year-old can be explained by the dominance of psychosocial factors and not hormones alone. Among the three patients reared as males, two prepubertal were satisfied with their male gender identity. The third patient, aged 32 years, had gender dysphoria when reared as a male that resolved when gender was reassigned as female and feminizing surgery was done. Conclusion: Gender assignment in 46 XX CAH is guided by factors such as degree of virilization of genitalia, gender orientation, patient involvement, sociocultural, and parental influences.

  16. Rhizosphere size

    Estimation of the soil volume affected by roots - the rhizosphere - is crucial to assess the effects of plants on properties and processes in soils and dynamics of nutrients, water, microorganisms and soil organic matter. The challenges to assess the rhizosphere size are: 1) the continuum of properties between the root surface and root-free soil, 2) differences in the distributions of various properties (carbon, microorganisms and their activities, various nutrients, enzymes, etc.) along and across the roots, 3) temporal changes of properties and processes. Thus, to describe the rhizosphere size and root effects, a holistic approach is necessary. We collected literature and own data on the rhizosphere gradients of a broad range of physico-chemical and biological properties: pH, CO2, oxygen, redox potential, water uptake, various nutrients (C, N, P, K, Ca, Mg, Mn and Fe), organic compounds (glucose, carboxylic acids, amino acids), activities of enzymes of C, N, P and S cycles. The collected data were obtained based on the destructive approaches (thin layer slicing), rhizotron studies and in situ visualization techniques: optodes, zymography, sensitive gels, 14C and neutron imaging. The root effects were pronounced from less than 0.5 mm (nutrients with slow diffusion) up to more than 50 mm (for gases). However, the most common effects were between 1 - 10 mm. Sharp gradients (e.g. for P, carboxylic acids, enzyme activities) allowed to calculate clear rhizosphere boundaries and so, the soil volume affected by roots. The first analyses were done to assess the effects of soil texture and moisture as well as root system and age on these gradients. The most properties can be described by two curve types: exponential saturation and S curve, each with increasing and decreasing concentration profiles from the root surface. The gradient based distribution functions were calculated and used to extrapolate on the whole soil depending on the root density and rooting intensity. We

    Remarkable progress has been achieved in understanding the mechanisms controlling sex determination, yet the cause for many Disorders of Sex Development (DSD) remains unknown. Of particular interest is a rare XX DSD subtype in which individuals are negative for SRY, the testis determining factor on the Y chromosome, yet develop testes or ovotestes, and both of these phenotypes occur in the same family. This is a naturally occurring disorder in humans (Homo sapiens) and dogs (C. familiaris). Phenotypes in the canine XX DSD model are strikingly similar to those of the human XX DSD subtype. The purposes of this study were to identify 1) a variant associated with XX DSD in the canine model and 2) gene expression alterations in canine embryonic gonads that could be informative to causation. Using a genome wide association study (GWAS) and whole genome sequencing (WGS), we identified a variant on C. familiaris autosome 9 (CFA9) that is associated with XX DSD in the canine model and in affected purebred dogs. This is the first marker identified for inherited canine XX DSD. It lies upstream of SOX9 within the canine ortholog for the human disorder, which resides on 17q24. Inheritance of this variant indicates that XX DSD is a complex trait in which breed genetic background affects penetrance. Furthermore, the homozygous variant genotype is associated with embryonic lethality in at least one breed. Our analysis of gene expression studies (RNA-seq and PRO-seq) in embryonic gonads at risk of XX DSD from the canine model identified significant RSPO1 downregulation in comparison to XX controls, without significant upregulation of SOX9 or other known testis pathway genes. Based on these data, a novel mechanism is proposed in which molecular lesions acting upstream of RSPO1 induce epigenomic gonadal mosaicism.

    Full Text Available En el siglo XX podemos distinguir dos grandes ciclos políticos de onda larga. En el primero las dictaduras son fuertes y la democracia encuentra serias dificultades para mantenerse. En el segundo los regímenes autoritarios son los débiles y la democracia se extiende y fortalece. Estos ciclos coinciden con otros de tipo económico. La concordancia se debe a que los problemas de cada ciclo económico se abordan de manera más eficaz desde las correspondientes formas políticas generadas por los imperativos de la economía. Igual que las crisis de 1920 y 1929 contribuyeron a la expansión del fascismo y del autoritarismo, las de 1973 y 1979 coadyuvaron a la de la democracia. Este postulado no debe interpretarse de manera mecanicista; se trata de explicar un proceso histórico general, el de las transiciones democráticas del último cuarto del siglo XX, investigando una de las claves, quizá la más importante, las fluctuaciones de la economía.In the 20th century, we can differentiate two major long wave political cycles. In tfie first one, dictatorstiips become strong, while democracy finds itself at great pains to maintain its claims. In the second cycle, authoritarian regimes weaken and democracy spreads and grows stronger. There two cycles coincide with others of economic nature. This coincidence is due to the fact that in each economic cycle, problems are more efficiently deait with as seen from their corresponding political Systems, generated in turn by the imperativos of economy. In the same way as the crisis of 1920 and 1929 contribute to expand fascism and authoritarianism, so those of 1973 and 1979 also favoured the expansión of democracy. This postúlate should not be interpreted in a mechanistic way; we are trying to explain a general historical process, the transitions to democracy in the final quarter of the 20th century, investigating one of the key factors, perhaps the fundamental one, which is the fluctuations in economy.

Corruption as a complex social phenomenon that occurs in the process of socio-economic, political and social relations has become one of the most pressing political, social and economic problems of modern Russia. The corruption in the state apparatus not only cause serious, sometimes unsolvable problems for the citizens, but also hinder the normal functioning of the administrative bodies and authorities. The legal component, the development and adoption of relevant laws perform a special role in combating corruption. For many centuries government has repeatedly attempted if not to eliminate or at least to curb corruption in numerous managerial and administrative apparatus. The greatest interest in this regard is the imperial period of Russian history. The authors study the history of the development of criminal and civil law in the Code of the Russian Empire Publishing Laws 1832 of the penal Code and criminal Corrections 1845 judicial statutes in 1864 and subsequent legislation late XIX – the beginning of the XX century, the history of the development of appropriate laws, trace the change in order to prosecute and the degree of responsibility of the officials on the basis of unpublished material of the State Council, the State Duma and the Ministry of Justice, are stored in the Russian State Historical Archive, as well as the published acts of the Russian legislation, the verbatim records of the State Duma and the Council of State.

    Full Text Available The author of the article highlights the specific problems, solved by the artists in the field, in line with the general trends of plastic art development in the Republic of Moldova. At the beginning of the XX century, sketches prevailed, coupled with the unique desire to perceive the leisurely life of a provincial city. The unpretentious motifs reflected unexpectedly the observations and the state of mind of the authors even after the institution of the Soviet power. The tendency of the transformation of nature into lyrical images became a stable one in the creation of many artists. In the mid-1960s, the tendency towards decorative and monumental expressiveness grew. The re-evaluation of the experience of the European plastic artists was especially fruitful, fact confirmed not only by large-sized paintings, but also by the sketches, which thanks to a well-thoughtful idea obtained the value of the realized image. Almost all artists’ creations are linked to Chisinau where most of them live. The “tourist’s vision”, which reflects the impressions of the journeys in other regions, also becomes typical including landscapes with easily recognizable architectural constructions. However, the developed perception of the plastic imagination of the artists can often lead to unexpected interpretations of the objects. The aesthetic value of the works is in accordance with the originality of the author’s thinking, his ability to inspire the technical material, the unrepeatable intonations of artistic expression.

    Women are more susceptible to multiple sclerosis (MS) and have more robust immune responses than men. However, men with MS tend to demonstrate a more progressive disease course than women, suggesting a disconnect between the severity of an immune attack and the CNS response to a given immune attack. We have previously shown in an MS model, experimental autoimmune encephalomyelitis, that autoantigen-sensitized XX lymph node cells, compared with XY, are more encephalitogenic. These studies demonstrated an effect of sex chromosomes in the induction of immune responses, but did not address a potential role of sex chromosomes in the CNS response to immune-mediated injury. Here, we examined this possibility using XX versus XY bone marrow chimeras reconstituted with a common immune system of one sex chromosomal type. We found that experimental autoimmune encephalomyelitis mice with an XY sex chromosome complement in the CNS, compared with XX, demonstrated greater clinical disease severity with more neuropathology in the spinal cord, cerebellum, and cerebral cortex. A candidate gene on the X chromosome, toll-like receptor 7, was then examined. Toll-like receptor 7 expression in cortical neurons was higher in mice with XY compared with mice with XX CNS, consistent with the known neurodegenerative role for toll-like receptor 7 in neurons. These results suggest that sex chromosome effects on neurodegeneration in the CNS run counter to effects on immune responses, and may bear relevance to the clinical enigma of greater MS susceptibility in women but faster disability progression in men. This is a demonstration of a direct effect of sex chromosome complement on neurodegeneration in a neurological disease.

Um ponto importante que a investigação sobre o acontecimento traz para os estudos semióticos é a possibilidade de traduzir as operações discursivas de determinados textos, em termos de regimes discursivos do fato ou do acontecimento, a partir do reconhecimento de duas lógicas operantes distintas, respectivamente a implicativa e a concessiva. Este artigo faz parte de uma investigação maior que procura depreender e descrever as operações discursivas de algumas obras representativas do discurso literário do século XX, nas quais o “acontecimento” parece exercer um papel significativo. A título de ilustração das refl exões desenvolvidas no presente texto, serão abordadas obras de autores como Jean-Paul Sartre, Franz Kafka, Dino Buzzati e Samuel Beckett.

    Full Text Available El objetivo de este trabajo es analizar los cambios sociodemográficos más significativos ocurridos en los hogares latinoamericanos durante la segunda mitad del siglo xx. Para ello se tienen en cuenta dos aspectos fundamentales: la posible convergencia hacia las familias pequeñas y nucleares; y la naturaleza e incremento de los hogares con jefatura femenina. Se intenta no sólo sintetizar el conocimiento existente sobre dichos temas, sino también dar cuenta de las conexiones entre los cambios sociodemográficos de los hogares y la desigualdad social y de género persistente en América Latina. Algunas de las principales conclusiones son: a A pesar de la existencia de un claro proceso de nuclearización en los hogares latinoamericanos, la importancia de los arreglos familiares de tipo extendido continúa siendo distintiva del sistema familiar en la región, especialmente entre la población de escasos recursos; y b los hogares encabezados por mujeres muestran un claro incremento, y posiblemente éste se aprecie en diversos sectores de nuestras sociedades.

    Full Text Available El artículo propone una aproximación a la poesía neovanguardista hispanoamericana de raigambre experimental, durante la segunda mitad del siglo XX. Se advierte la dimensión continental de la emergencia de movimientos, agrupaciones, revistas y autores neovanguardistas a partir de fines de los años 50 y hasta los años 80 al menos. Lo anterior ha producido una nueva semioticidad que emparenta la escritura poética con las artes visuales, escénicas, musicales, audiovisuales y digitales, generando nuevos discursos y nuevos repertorios. Estos procesos suponen el reciclaje y resemantización de los de los ideales antiartísticos de tradición vanguardista y, particularmente, del proyecto arte-vida, revitalizando la relación entre arte y política, en consonancia con los debates públicos y las transformaciones en los sistemas de producción cultural. Se analizan como ejemplos de poesía experimental, visual y accional, a dos poetas chilenos: Cecilia Vicuña y Juan Luis Martínez.

    Full Text Available SAE 9260 type steels have silicon and carbon contents similar to those of the ductile iron matrix, and present a bainitic transformation with the same characteristics as ADI (Austempered Ductile Iron. The hypothesis is that excellent mechanical properties can be obtained by means of austempering (in times so short as to be accessible from the industrial point of view, the same as in ADI and even better because it is a rolling material instead of a cast material. It will be compared with the mechanical properties obtained by quenching and tempering at different temperatures.

    La composición química de los aceros SAE 92XX es similar a la de la matriz metálica de una fundición esferoidal, por lo que se pensó en someter a un acero de ese tipo a tratamientos de austempering similares a los que se aplican para lograr una ADI (Austempered Ductile Iron, y verificar si se alcanzaban valores aceptables de plasticidad con elevados valores de resistencia a la tracción para el mismo acero, tal y como sucede con aquellas fundiciones, y comparar dichos resultados con los obtenidos en el mismo acero con tratamientos convencionales de temple y revenido. Se alcanzaron valores que demostraron que, por austempering, se logran excelentes valores de plasticidad, muy superiores a los alcanzados por temple y revenido para durezas del mismo orden.

    In this study, the annual cycle of the gonadal steroids testosterone (T), 11-ketotestosterone (11-KT), 17β-oestradiol (E2) and 17α, 20β-dihydroxy-4-pregnen-3-one (DHP) was determined using radioimmunoassay and then compared, for XY males (n=35) and sex-reversed XX males (n=27) rainbow trout, to establish possible endocrinology differences. Both in XY males and sex-reversed XX males, significant correlation was shown between body weight and T (r=0.5046 and 0.34078, respectively; psex-reversed XX males were similar and showed an intense seasonal variation. The highest levels for T and 11-KT were detected from December to April with a peak in January (51.67 ± 5.11 and 61.95 ± 4.25 ng/ml, for XY males and 57.1 ± 5.82 and 59.27 ± 4.84 ng/ml, respectively, for XX males). In addition, there was a positive correlation (psex-reversed XX males (r=0.6019). Concentrations of DHP in XY males also showed seasonal variation with a peak in February (25.18 ± 12.99 ng/ml). However, DHP levels in sex-reversed XX males were undetectable (sex-reversed XX males were similar to those observed in XY males. The only difference in the annual gonadal steroid cycle between XY and sex-reversed XX males was in the DHP profile. © 2009 Blackwell Verlag GmbH.

    It is well accepted that Forkhead box protein L2 (Foxl2) and aromatase (Cyp19a1; the enzyme responsible for estrogen synthesis) are critical for ovarian development in vertebrates. Knockouts of Foxl2 and Cyp19a1 in goat, mouse, and zebrafish have revealed similar but not identical functions across species. Functional analyses of these two genes in other animals are needed to elucidate their conserved roles in vertebrate sexual development. In this study, we established foxl2 and cyp19a1a mutant lines in Nile tilapia. Both foxl2-/- and cyp19a1a-/- XX fish displayed female-to-male sex reversal. Sf1, Dmrt1, and Gsdf were upregulated in the foxl2-/- and the cyp19a1a-/- XX gonads. Downregulation of Cyp19a1a and serum estradiol-17β level, and upregulation of Cyp11b2 and serum 11-ketotestosterone level were observed in foxl2-/- XX fish. The mutant phenotype of foxl2-/- XX individuals could be rescued by 17β-estradiol treatment from 5 to 30 days after hatching (dah). Upregulation of Star1, the enzyme involved in androgen production in tilapia, was also observed in the foxl2-/- XX gonad at 30 and 90 dah. In vitro promoter analyses consistently demonstrated that Foxl2 could suppress the transcription of star1 in a dose-dependent manner. In addition, compared with the control XX gonad, fewer germ cells were detected in the foxl2-/- XX, cyp19a1a-/- XX, and control XY gonads 10 dah. These results demonstrate that Foxl2 promotes ovarian development by upregulating Cyp19a1a expression and repressing male pathway gene expression. These results extend the study of Foxl2 and Cyp19a1a loss of function to a commercially important fish species. Copyright © 2017 Endocrine Society.

    Full Text Available The entire XX century has passed in turbulent political and economic changes in the entire world, and especially in Europe. This was particularly expressed on the terri- tory of the Kingdom of Yugoslavia and Socialist Federal Republic of Yugoslavia (SFRY, were a few independent states were created at the beginning of XX century. All these changes reflected also in the field of culture and science and created ob- stacles for many cultural events, and especially scientific researches of certain phenome- na in these territories at the beginning of the XXI century. These difficulties will continue to be present for many years because the SFRY was disintegrated in wars, violence and crimes resulting in impossibility to establish faster normal collaboration between the newly created states. This problem has not speared even the researches in history of physical culture of the XX century on the territory of former SFRY, because no normal communication bet- ween some of the newly formed states has been established, so the access to researches of primary historic resources, which is necessary in heurictc phase, is lacking. Therefore it is necessary to establish collaboration between colleagues-resear- chers from these territories, more that usually in order to create possibilities for valid researches with objective and worthy conclusions

    Steroidogenic factor 1 (NR5A1, SF‐1, Ad4BP) is a transcriptional regulator of genes involved in adrenal and gonadal development and function. Mutations in NR5A1 have been among the most frequently identified genetic causes of gonadal development disorders and are associated with a wide phenotypic spectrum. In 46,XY individuals, NR5A1‐related phenotypes may range from disorders of sex development (DSD) to oligo/azoospermia, and in 46,XX individuals, from 46,XX ovotesticular and testicular DSD to primary ovarian insufficiency (POI). The most common 46,XY phenotype is atypical or female external genitalia with clitoromegaly, palpable gonads, and absence of Müllerian derivatives. Notably, an undervirilized external genitalia is frequently seen at birth, while spontaneous virilization may occur later, at puberty. In 46,XX individuals, NR5A1 mutations are a rare genetic cause of POI, manifesting as primary or secondary amenorrhea, infertility, hypoestrogenism, and elevated gonadotropin levels. Mothers and sisters of 46,XY DSD patients carrying heterozygous NR5A1 mutations may develop POI, and therefore require appropriate counseling. Moreover, the recurrent heterozygous p.Arg92Trp NR5A1 mutation is associated with variable degrees of testis development in 46,XX patients. A clear genotype‐phenotype correlation is not seen in patients bearing NR5A1 mutations, suggesting that genetic modifiers, such as pathogenic variants in other testis/ovarian‐determining genes, may contribute to the phenotypic expression. Here, we review the published literature on NR5A1‐related disease, and discuss our findings at a single tertiary center in Brazil, including ten novel NR5A1 mutations identified in 46,XY DSD patients. The ever‐expanding phenotypic range associated with NR5A1 variants in XY and XX individuals confirms its pivotal role in reproductive biology, and should alert clinicians to the possibility of NR5A1 defects in a variety of phenotypes presenting with gonadal

La incorporación de un número significativo de inmigrantes a finales del siglo XIX junto a un proceso de reorganización productiva asociado al desarrollo de la industria vitivinícola, implicó cambios en las relaciones sociales y en las condiciones de vida de amplios sectores de la población mendocina. Iniciado el siglo XX, la vitivinicultura se convirtió en la principal actividad productiva de la provincia y la más importante en su rubro a nivel nacional. Los viñateros, productores agroindustriales, industriales bodegueros, contratistas de viñas , etc., fueron constituyéndose en parte de una sociedad cada vez más heterogénea y diversa, producto del desarrollo capitalista que experimentó la región desde el último tercio del siglo XIX y que se insertó en el proceso de incorporación de la economía Argentina al mercado mundial. Este período resulta de suma importancia porque se determinó un sistema productivo en torno a la actividad vitivinícola de la provincia que dio forma al mercado de trabajo regional. En este contexto, la inserción de los trabajadores se dio de una manera muy dispar en el proceso productivo, caracterizado por una alta estacionalidad y una escasa especialización de la mano de obra requerida.The aim of this work is to analyze the changes and continuities during the process of formation of the labor market in the province of Mendoza in the early 1900s. Wide sectors of the Mendoza population saw their life conditions and social interactions change as a result of the absorption of a significant amount of immigrants by the end of 19 th century, together with a restructuring of production connected to the development of the wine industry. Shortly after the turn of the century, wine had become the main productive activity of that

    Full Text Available Purpose of the article is to analyze the philosophical and cultural ideas about television, which is a leading visual practice of XX century. It does not lose its relevance in the beginning of the XXI. The role of television lies in visual presentation and formation of the basic norms of taste and traditions of different social groups. Television is the leading communicative practice, which consideration is represented differently in modern science. Research methodology involves an appeal to the philosophical and cultural concepts, representing different approaches to the understanding of television. The paper considers the views of Western scholars, such as R. Arnheim, M. Wolff, A. Kroker, G. Lipovetsky, M. McLuhan, D. Mulvin, J. Mittell, N. Postman, L. Saffhil, J. Sterne, E. Thompson, J. Fiske, S. Shapiro. During analysis of the issue of the specific nature of television content the works of Russian scientists – T. Savitskaya, N. Samutina and Polish contemporary author – R. Sapenko were used. Originality lies in the depiction of the main approaches to the study of television as a visual communicative practice. Deployment of the author's position within the designated issues is presented as a historical digression – from the first attempts at understanding the phenomenon of television to the newest scientific theories that have found expression in contemporary American philosophical and cultural thought. Results of the study can be used in the training course "Visual communication and practices." Conclusions indicated that the majority of contemporary visual practices based on certain patterns, embedded TV. Despite the emergence of new media practices, TV does not lose relevance, everywhere present in the culture, which means that his research will allow a better understanding of the specificity of cultural creativity process.

Lo primero es que en la construcción mutua de nuestras identidades, estas se han basado durante períodos prolongados en la imagen del otro como un vecino amenazante, con lo cual las relaciones bilaterales tienden a ser percibidas como un juego en donde alguien pierde a costa de las ganancias del otro. Lo segundo es que la relación con nuestros vecinos, incluso con aquellos como en el caso de Argentina han tenido una mejoría significativa al menos desde la década de los 90s con la recuperación de la democracia en ambos países, ha mantenido cursos zigzagueantes entre la cooperación y el conflicto. Lo tercero es un notorio contraste entre la tendencia a la continuidad en la política exterior de Chile en relación a los temas vecinales, independiente del tipo de gobierno que exista, esta continuidad se ha explicado como política de estado, sin embargo, por sus características, esta difícilmente cumple con los estándares de una efectiva política de estado. De manera contrastante, las fluctuaciones en las políticas exteriores de nuestros vecinos han dependido del alto grado de personalismo en las decisiones, la menor institucionalización de la política interna y/o de las fluctuaciones en la popularidad de los gobernantes.

    The metaphorical applications of heavenly bodies and phenomena in Western Armenian poetry at the beginning of the XX century are very diverse and of great variety. Art Workers eulogize the creation of God, admire the beauty of stars, and perceive the man as a part of nature and in the close connection with all other parts. These units are often used for bringing to light one's inner life, his old gone paths, expectations and hopes, many times they become the heart and the basis of poetical image and create unique beauty.

    The article presents results of analysis of works of late XIX--first quarter of XY centuries devoted to problems of social hygiene. It is established that origin of social hygiene was directly related to crucial revision of conceptions of causes and essence of diseases that created necessary conditions for transfer into medicine ideas and methods of political economy, sociology and eugenics. It is proved that origin of social hygiene was appropriate consequence of those crucial alterations in mass physician's consciousness that characterize scientific revolution in medicine of late XIX--first half XX centuries.

    The conditions for sex reversal in vertebrate species have been studied extensively and have highlighted numerous key factors involved in sex differentiation. We review here the history of the development of knowledge, referring to one example of complete female-to-male XX sex reversal associated with a polled phenotype in the goat. The results and hypotheses concerning this polled intersex syndrome (PIS) are then presented, firstly with respect to the transcriptional regulatory effects of the PIS mutation, and secondly regarding the role of the main ovarian-differentiating factor in this PIS locus, the FOXL2 gene.

  9. El tribunal tutelar de Sevilla, una alternativa para los menores delincuentes a principios del siglo XX

    2015-04-01

    Full Text Available El estudio de la atención a la infancia delincuente y de todas las instituciones encargadas de su tutela y educación es un asunto poco estudiado en Andalucía y en concreto en Sevilla. Hasta la implantación de los Tribunales para niños en España, el tratamiento de menores delincuentes tomaba el camino del hospicio o el de la cárcel de adultos. Existían escasos centros donde además de acogerlos se les diera educación. Hasta la época de entre siglos no hay una verdadera preocupación por el asunto, tanto en América como en Europa. En España, la protección de menores como empresa pública, organizada y regulada por el Estado, aparece a principios del siglo XX. Se origina en el marco de un movimiento de reforma social a partir de 1900, impulsado decididamente desde el Gobierno por la vía de la legislación social. Todo ello transformaría el Estado liberal-burgués en un Estado social de Derecho. Hubo una creciente concienciación por el tema que se reflejó en los temas de congresos, en publicaciones de libros y artículos. La preocupación se concretó en la Ley de Tribunales Tutelares de menores de 1918, con una jurisdicción especial que impedía su internamiento en prisiones. Para su funcionamiento, eran necesarias las instituciones auxiliares: las casas de observación y las casas tutelares o reformatorios. El retraso en su expansión se debe a que no existía presupuesto para crear todas las infraestructuras en cada provincia. En Sevilla hubo un movimiento intenso a través de la prensa para que se creara, en consonancia con lo que ocurría a nivel nacional. Y a pesar del interés político, tanto de instituciones judiciales, educativas o municipales no se implantó hasta 1930. La prensa será el impulso que necesitaba la ciudad para animar a su creación.

He partido de la base de que el carlismo es un movimiento más complejo de analizar de lo que a simple vista parece; que su evolución no ha sido lineal, y que no se puede hablar de uno, sino de varios carlismos. En este trabajo me he centrado en los acontecimientos que ha venido reivindicando el sector más progresista del mismo, y que de alguna manera son la justificación de su evolución hacia la izquierda, pero sin desdeñar otros aspectos que estarían más próximos al sector tradicionalista. He focalizado la evolución político-cultural del carlismo en los siguientes aspectos: la religiosidad; la sociabilidad en los Círculos Culturales; la defensa de las culturas autóctonas periféricas; la cultura obrera y sindical; la cultura juvenil y estudiantil; la cultura de la violencia; fiestas, ritos y conmemoraciones carlistas; y la evolución cultural e ideológica, incluyendo el papel de las mujeres.Across a few facts and events that have been given in the carlist movement during the 20th century, I have tried to shape the development or evolution of its political culture.

    Full Text Available In the article the system of taxation of Orthodox parishes of the Russian Empire in the late XIX — early XX centuries is reconstructed on the new archival materials and the numerous contributions that the parishes carried out from its own funds in favor of the diocesan institutions and charitable organizations are described. Attempt are made to estimate the number of different charges, which existed in this period (the author now includes over 80 items and their size and severity for the parish budget. In this regard, it is concluded that such deductions in some cases accounted for more than half of the income of the parish churches. The author describes the reasons for turning the formally voluntary fees in favor of charitable institutions in virtually compulsory. It investigates the failed attempts of the Supreme Church leadership to reform the system of parish charges in the early XXth century, in particular, the work of the two synodal committees (active in 1905 under the chairmanship of Archbishop Nikon (Sofi yskiy and in 1909, under the chairmanship of Archbishop Anthony (Khrapovitsky. The author comes to the conclusion that these charges were not the only cause of poverty of many parishes (especially rural parishes in Central Russia, but they weakened the parish as a religious community, for the charges were a pretext for permanent discontent among the parishioners about the parish clergy and diocesan authorities. Not the last role here was played by the fact that the diocesan institutions, which were funded by the parish funds were of an estate character.

    XX sex reversal is known in 17 breeds of dogs. In the American cocker spaniel, it segregates as an autosomal recessive trait, and the affected animals lack the testis determining Sry gene. In the search for an autosomal gene that causes this trait, we considered the possibility of Lhx9, a gene encoding LIM homeobox containing transcription factor 9, as a candidate gene. An American cocker spaniel pedigree showing Sry-negative XX sex reversal phenotype was genotyped with an intronic Lhx9 microsatellite marker. Segregation of the Lhx9 marker in the pedigree indicated that a mutation in canine Lhx9 is not likely to be the cause of Sry-negative XX sex reversal. In addition, using the recently available 7.6X canine genomic sequence, we report the location and genomic organization of canine Lhx9.

Laboratory evaluations, imaging studies, ovarian biopsy, G-banding karyotype, and in situ fluorescence hybridization. Clinical and laboratory findings. A karyotype: mos 47,XXX/45X/46,XX was found in the cytogenetic studies, a bicornuate uterus in the ultrasonographic scan, and a normal ovarian profile in the laboratory tests. The infertility in the present case can be related to either bicornuate uterus or subclinical abortions due to aneuploid ova. Cytogenetic assessment provides important information regarding infertile patients with uterine factors and short stature.

    Fetal congenital chylothorax is a rare condition that occurs sporadically or can be associated with abnormal karyotype or structural chromosomal anomalies. We report a unique case of fetal congenital bilateral chylothorax associated with mosaicism 47,XXX/46,XX. A female fetus affected by massive bilateral hydrothorax and ascites was diagnosed at 34(+1) weeks of gestation. Previous ultrasonographic exams were completely normal. Immune causes of hydrops were excluded. Elective cesarean section was performed soon after bilateral thoracocentesis. The analysis of drained pleural fluid revealed its lymphatic nature. The fetal karyotyping, performed on chorionic villi at the 11th week, had shown mosaicism 47,XXX/46,XX, later confirmed in the newborn's blood. We hypothesized that chylothorax may be part of the phenotypic spectrum of 47 XXX karyotype and we suggest an ultrasound follow-up of the fetus at closer intervals than the routine timing for this condition, even if it is not usually characterized by severe phenotypic features. © 2013 The Authors.

    2012-10-01

    Full Text Available Em face da acentuada revalorização da textualidade nas poéticas da década de 1960 em Portugal – perspectiva que, com algumas especificidades, também se verifica no contexto francês e espanhol –, a demarcação dos poetas emergentes na década seguinte é, por vezes, fortemente reactiva. Mas haverá uma diferença essencial entre estas duas inflexões, corporizadas em poéticas aparentemente distintas? E haverá algum momento, na segunda metade do século XX, em que efectivamente se concretize uma ruptura? No presente estudo, procura-se mostrar que, mais do que produzir uma ruptura, as poéticas emergentes nos anos sessenta do século XX consolidam uma tradição de modernidade escolhendo a sua vertente mais radical, enquanto as poéticas subsequentes preferem reatar a tradição mais remota da modernidade, em sentido baudelairiano. Apesar de estarmos perante dois diálogos diferentes com a tradição, é possível observar que, em ambos os casos, esta é retomada a um ponto que nos impede de falarmos de ruptura.

    Full Text Available Los cambios producidos en la música del siglo XX se han observado habitualmente desde la perspectiva del compositor y muy poco o casi nada desde las perspectivas del intérprete, del público y de la industria musical. Es desde la producción del compositor que se ha construido canon y se ha aplicado juicio estético. Sin embargo, estos tres eslabones fundamentales de la cadena de la música también desarrollaron agendas propias en dichos cambios, que es necesario considerar para hacer más justa nuestra valoración del siglo XX musical y su consiguiente construcción canónica. En este artículo, me centro en el papel desarrollado por estos tres eslabones a partir de la segunda posguerra, considerando el alejamiento del público del lenguaje serial, el auge de la música antigua y sus modos de interpretación históricamente informados, el desarrollo de una música popular de concierto, y la definición del género musical desde la performance y la escucha.

    The perception of gender development of individuals with complete androgen insensitivity syndrome (CAIS) as unambiguously female has recently been challenged in both qualitative data and case reports of male gender identity. The aim of the mixed-method study presented was to examine the self-perception of CAIS individuals regarding different aspects of gender and to identify commonalities and differences in comparison with subfertile and infertile XX-chromosomal women with diagnoses of Mayer-Rokitansky-Küster-Hauser syndrome (MRKHS) and polycystic ovary syndrome (PCOS). The study sample comprised 11 participants with CAIS, 49 with MRKHS, and 55 with PCOS. Gender identity was assessed by means of a multidimensional instrument, which showed significant differences between the CAIS group and the XX-chromosomal women. Other-than-female gender roles and neither-female-nor-male sexes/genders were reported only by individuals with CAIS. The percentage with a not exclusively androphile sexual orientation was unexceptionally high in the CAIS group compared to the prevalence in "normative" women and the clinical groups. The findings support the assumption made by Meyer-Bahlburg ( 2010 ) that gender outcome in people with CAIS is more variable than generally stated. Parents and professionals should thus be open to courses of gender development other than typically female in individuals with CAIS.

  1. Determination of unbound ticagrelor and its active metabolite (AR-C124910XX) in human plasma by equilibrium dialysis and LC-MS/MS.

    Ticagrelor is the first direct acting reversibly binding oral platelet P2Y(12) receptor antagonist. The parent molecule and the main metabolite (AR-C124910XX) are both able to block adenosine diphosphate-induced receptor signaling with similar potency. Drug binding to plasma proteins reduces free drug available for pharmacologic activity. Therefore, assessing unbound drug is important for interpretation of pharmacokinetic/pharmacodynamic findings. This paper describes the development and validation of an equilibrium dialysis/LC-MS/MS method for measuring unbound ticagrelor and AR-C124910XX in human plasma. Plasma samples (200μl) were dialysed against phosphate buffered saline (37 °C, 24h) in 96-well dialysis plates to separate unbound analytes. Drug-protein binding alterations during dialysis were minimized by maintaining physiologic conditions (pH 7.4, 37 °C). Ticagrelor and AR-C124910XX were quantified in dialysates (unbound fraction), retentates and plasma (total concentration) using liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS) methods. Calibration curves were established for the retentate and plasma (total concentration) in the ranges 5-5000 ng/ml (ticagrelor) and 2.5-2500 ng/ml (AR-C124910XX), and for the dialysate in the range 0.25-100 ng/ml (both analytes). Both ticagrelor and AR-C124910XX were highly protein bound (>99.8%), i.e. unbound fraction <0.2%. Yet, the methodology was successfully applied to determine unbound concentrations of ticagrelor and AR-C124910XX in clinical samples. Copyright © 2011 Elsevier B.V. All rights reserved.

    entonces en Valencia una demanda local de instrumentos que justificaba suficientemente su labor. Se han obtenido datos de cuatro fábricas de pianos que funcionaron entre 1830 y principios del siglo XX. Dicha documentación constata que los instrumentos valencianos construidos durante aquel período (1830-1915 obtuvieron gran aceptación tanto en el mercado interno como en el foráneo, y consiguieron prestigiosos galardones en exposiciones y muestras nacionales y extranjeras. También se ha facilitado el conocimiento de los sistemas de producción y comercialización de aquellos talleres, y de las características organológicas que poseyeron los pianos valencianos construidos en las diversas épocas; esa información ha ayudado a valorar la función económica y social que tuvo la fabricación valenciana de pianos en el siglo XIX y ha permitido su comparación con la desarrollada en otras provincias españolas durante la misma época.

    Full Text Available The Cathedral of Vitoria is a building with an extended historical life. We have attempted to produce a chronological sequence of the interventions and architectural “projects” since the beginning of the construction of the church on the early 13th century to the last restorations during the 1960s. This study attempts to fill a void on the available information, crucial for the evaluation of safety and durability issues on the Cathedral. The “anamnesis” practiced on the monument is one of the cornerstones of the method we have chosen for restoration, not only regarding the structural aspects, but regarding the problems of functional interpretation and symbolic content as well. This historical reading the key of structural analysis is what we intend to present: the extraction of the historical building sequence that leads to the current situation of the building, discriminating the different moments of the architectural project, phases of building growth and repair interventions on the structure that comment on or contradict among themselves, to result in the form that we witness now. We use that sequence to evaluate, albeit partially, the safety status of the structure, and to build a working hypothesis for the structural aspects of the restoration tasks.La Catedral de Vitoria es un edificio con una larga vida histórica, llena de acontecimientos constructivos que han venido interesando su comportamiento como estructura construida.

    Full Text Available Este trabalho visa a refletir sobre a violência, o preconceito e a exclusão social a partir de algumas obras específicas da literatura brasileira produzidas no século XX. Particularmente, deu-se destaque a autores em cujas obras há a representação de grupos marginalizados que sofrem com a violência e a discriminação em razão do status social, do preconceito racial e sexual. A partir da referência a textos de autores como Graciliano Ramos, Clarice Lispector, Caio Fernando Abreu, Luiz Silva e Rubem Fonseca, chegou-se à conclusão de que a violência, no Brasil, é algo histórico e socialmente legitimado, garantindo os processos de discriminação e de exclusão social, que se fazem representar na literatura.

  10. Peasant Women Crime in Russia (the Second Half of the XIX – First Half of the XX Century

    2016-07-01

    Full Text Available The article is devoted to the main features of women's peasant crime during the post-reform period in Russia. The importance of this problem is caused for that relevant topics are presented due to the parallels between the current state of Russian society, in which the peasant values and mentality are still retained, and the state of society at the boundary of XIX - XX centuries. The value of a woman in peasant life was as determinative as the value of a man. The country’s radical changes that were taking place in the post-reform period through the prism of the female deviant behaviour create a new perspective, which contributes to a better understanding of Russia's past and its impact on the present.

    We have observed spectra from highly charged zinc ions in a variety of laser-produced plasmas. Spectral features that are Na - and Mg -like satellites to high- n Rydberg transitions in the Ne -like Zn XXI spectrum are analyzed and modeled. Identifications and analysis are made by comparison with highly accurate atomic structure calculations and steady state collisional-radiative models. Each observed Zn XX and Zn XIX feature comprises up to approximately 2 dozen individual transitions, these transitions are excited principally by dielectronic recombination through autoionizing levels in Na - and Mg -like Zn19+ and Zn18+. We find these satellites to be ubiquitous in laser-produced plasmas formed by lasers with pulse lengths that span four orders of magnitude, from 1 ps to approximately 10 ns. The diagnostic potential of these Rydberg satellite lines is demonstrated.

    Full Text Available A través de este artículo se ha intentado dar una explicación —dentro del contexto español— al tradicional vínculo entre republicanismo, anticlericalismo y masonería. Para ello hemos recurrido a analizar la trayectoria de un hombre público, Carlos Esplá, que responde plenamente al perfil esencial del republicano del primer tercio del siglo XX. Se ha querido, otra cosa es que se haya conseguido, demostrar como en muchos casos tal vinculación no respondía tanto a cuestiones dogmáticas, como a motivaciones racionalistas o coyunturales. Es decir, buena parte de los republicanos eran anticlericales y masones, lo que no quería decir que fuesen antirreligiosos, ni tampoco que cumpliesen con los ritos y las consignas del Grande Oriente. Ambas militancias estaban estrechamente ligadas a una coyuntura histórica específica.Through this article we have tried to explain —within the spanish context— the traditional link between republicanism, anticlericalism and masonry. For that reason we have resorted to analise he career of a republic man, Carlos Esplá, who perfectly answers to the profile of the republican of the first third of the xx Century. We have, we don't know if we have succeeded, to show how in lots of cases such a connection doesn't have to do with dogmatic questions as much as rationalistic or current motives. A great idea of republicans were anticlerical and masons, which didn't mean they were anti-religious, ñor that they followed the rites and instructions of the Great East. Both affiliations/tendencies were closely linked to a specific historical situation.

  3. Observations, light curves analysis and pulsation behavior of the Algol-type eclipsing binary system XX Cep

    We present the long term photometric variations of the classical Algol type binary XX Cep with a δ Scuti type pulsating component. Modeling of the system shows that the secondary component fills its Roche lobe. The derived physical and geometrical parameters of the system are M1=1.92M⊙, M2=0.36M⊙, R1=2.08R⊙, R2=2.39R⊙, L1=19.8L⊙, L2=2.1L⊙, a=9.8R⊙ and the distance of the system as 312(18) pc. We obtained five new times of minima. Analysis of the mid-eclipse times indicate a period decrease of dP/dt=-1.9(2)×10-8 days/yr that can be interpreted in terms of a mass transfer rate (dM/dt=-1.2(3)×10-9M⊙/yr) from the secondary to primary component. The O-C diagram formed from all available timings, and thus the orbital period of the system, can be partly represented as a beat effect between two cyclical variations with different periods (P1 = 48(1) yr, P2 = 81(4) yr). We used PHOEBE program for light curves analysis and after modeling, the eclipse and proximity effects were removed from the light curves to analyze intrinsic variations caused by components of the system. Frequency analysis was done by Period04 and the residuals represent the pulsation of a more massive component of the system XX Cep with a period of 0.031 days, confirming the results of Lee et al. (2007).

    Full Text Available Este artículo muestra de manera general la gran importancia de la fenomenología como un paradigma teórico clave, porque influyó de manera contundente en la ciencia y la filosofía del siglo xx. Su influencia se deja ver en los autores más conspicuos del existencialismo, del historicismo, de la hermenéutica, de la historia de la ciencia, de la filosofía analítica, de la llamada postmodernidad; su ascendiente es notable en personajes importantes de las místicas y las religiones contemporáneas. Aquí se señala también el surgimiento y la influencia de la fenomenología en pensadores mexicanos de mediados del siglo xx. Como filosofía, se opone al positivismo y a lo que Husserl llamó el "objetivismo", se muestra cómo la fenomenología reivindica la perspectiva del sujeto y se opone a la falta de voluntad y de método de diversas escuelas para esclarecer la intencionalidad. Se introduce a nociones básicas de esta corriente como son: "fenomenología trascendental", la perspectiva del sujeto, "reducción fenomenológica", "acto intencional" y "objeto intencional", "lo constituido" y "lo constituyente", para terminar con la presentación de lo que Husserl define como "psicología fenomenológica", que es un camino al autoconocimiento del individuo y la sociedad.

    Full Text Available O comunismo do século XX teve, desde seu início, uma dimensão dupla: o movimento revolucionário, por um lado; o sistema de poder estatal, por outro. Os dois aspectos são indissociáveis. A história do comunismo como movimento revolucionário em escala mundial está estreitamente ligada à história da Rússia e, em seguida, à da União Soviética. E o sistema soviético, na configuração definitiva que lhe foi impressa pelo stalinismo, foi ao longo de muitas décadas o modelo de referência para o conjunto do mundo comunista. Em outras palavras, o comunismo do século XX identifica-se primordialmente com a experiência histórica do poder soviético. Os demais comunismos, heréticos ou dissidentes em relação à ortodoxia stalinista, desempenharam um papel menos importante, freqüentemente marginal.Twentieth-century communism had, since the beginning, a double dimension: the revolutionary movement, on the one hand; the state power system, on the other. Both sides are inseparable. The history of communism as a revolutionary movement in world scale is intimately linked to the Russian and then Soviet history. And the Soviet system, in the final configuration stalinism gave to it, was a model to the whole communist world along many decades. So that twentieth-century communism is primordially identical with the historical experience of the Soviet power. Other brands of communism, heretical or dissident to Stalinist ortodoxy, performed a less important, often marginal, role.

Para caracterizar el parasitismo intestinal en niños de 1 a 12 años se realizó un estudio descriptivo transversal durante los meses de mayo a julio de 2007, en 2 comunidades, una suburbana del reparto "América Latina" y otra urbana del reparto "Virginia", ambas pertenecientes al área de salud del Policlínico "XX Aniversario", del municipio de Santa Clara. Se visitaron las viviendas y se aplicó encuesta a los padres para obtener datos al respecto. Fueron estudiados 243 niños de ambas comunidades, a quienes se les tomó muestras de heces fecales y región anal por el método de Graham. La frecuencia general de parasitismo fue de 65,8 %, mayor en los niños del reparto "América Latina", y las especies más frecuentes fueron Giardia lamblia y Enterobius vermicularis. Una inadecuada desinfección del agua, la presencia de vectores, comerse las uñas, la poca higiene después del contacto con animales, la presencia de estos en el hogar, no lavar las verduras, andar descalzos y el hacinamiento, fueron factores que favorecieron las parasitosis.Included in infectious diseases, yet at present times, intestinal parasitism is a problem for underdeveloped countries, and for those highly developed.

    Among the distinct strategies proposed to expand the genetic alphabet, sizeexpanded nucleobases are promising for the development of modified DNA duplexes with improved biotechnological properties. In particular, duplexes built up by replacing canonical bases with the corresponding benzo-fused counterparts could be valuable as molecular nanowires. In this context, this study reports the results of classical molecular dynamics simulations carried out to examine the structural and dynamical features of size-expanded DNAs, including both hybrid duplexes containing mixed pairs of natural and benzo-fused bases (xDNA) and pure size-expanded (xxDNA) duplexes. Furthermore, the electronic structure of both natural and size-expanded duplexes is examined by means of density functional computations. The results confirm that the structural and flexibility properties of the canonical DNA are globally little affected by the presence of benzo-fused bases. Themost relevant differences are found in the enhanced size of the grooves, and the reduction in the twist. However, the analysis also reveals subtle structural effects related to the nature and sequence of benzo-fused bases in the duplex. On the other hand, electronic structure calculations performed for xxDNAs confirm the reduction in the HOMOLUMO gap predicted from the analysis of the natural bases and their size-expanded counterparts, which suggests that pure size-expanded DNAs can be good conductors. A more complex situation is found for xDNAs, where fluctuations in the electrostatic interaction between base pairs exerts a decisive influence on the modulation of the energy gap.

It’s known that the concept of local civilizations is connected with conservatism. Liberalism with its universalism is commonly opposed to local civilizations paradigm. However, Russian liberal historiosophy of mentioned period, stating cultural and economic “Russian social organism” immaturity acknowledges intermediacy of Russia as culture and civilization, her transitive status between tradition to liberal ideal. Depicting this intermediacy with historical and local boundaries Russian liberal historiosophy of the middle of XIX – beginning of XX centuries doesn’t neglect local civilizations paradigm but creates its new implicit version.

    SOX9 mutations cause the skeletal malformation syndrome campomelic dysplasia in combination with XY sex reversal. Studies in mice indicate that SOX9 acts as a testis-inducing transcription factor downstream of SRY, triggering Sertoli cell and testis differentiation. An SRY-dependent testis-specific enhancer for Sox9 has been identified only in mice. A previous study has implicated copy number variations (CNVs) of a 78 kb region 517-595 kb upstream of SOX9 in the aetiology of both 46,XY and 46,XX disorders of sex development (DSD). We wanted to better define this region for both disorders. By CNV analysis, we identified SOX9 upstream duplications in three cases of SRY-negative 46,XX DSD, which together with previously reported duplications define a 68 kb region, 516-584 kb upstream of SOX9, designated XXSR (XX sex reversal region). More importantly, we identified heterozygous deletions in four families with SRY-positive 46,XY DSD without skeletal phenotype, which define a 32.5 kb interval 607.1-639.6 kb upstream of SOX9, designated XY sex reversal region (XYSR). To localise the suspected testis-specific enhancer, XYSR subfragments were tested in cell transfection and transgenic experiments. While transgenic experiments remained inconclusive, a 1.9 kb SRY-responsive subfragment drove expression specifically in Sertoli-like cells. Our results indicate that isolated 46,XY and 46,XX DSD can be assigned to two separate regulatory regions, XYSR and XXSR, far upstream of SOX9. The 1.9 kb SRY-responsive subfragment from the XYSR might constitute the core of the Sertoli-cell enhancer of human SOX9, representing the so far missing link in the genetic cascade of male sex determination.

    Full Text Available The article presents a historical overview of the development of the traditional economy of the indigenous population of Yakutia during the end of XIX – the 80-ies of XX century. Historical retrospective proposed by the authors traces the socio-economic characteristics of the rural areas of Yakutia over a long period. The development of the major traditional economies of rural Yakutia considered at eventful historical background. Different political and socio-economic factors highlighted: they dictated the trends in cattle breeding and agriculture. It was found that, due to the remoteness from major economic centers, poor transport communications, as well as unfavorable climate in Yakutia formed a special type of rural economy. The authors pay particular attention to the negative impact of collectivization policies on agriculture, aggravated by natural disasters and hardships during the Great Patriotic War. In the study of factors of the agricultural development the authors positively evaluated the experience of scientific support and the implementation of scientific and technological progress for traditional sectors of economy. The analysis of published and unpublished sources convinces in following: despite a series of administrative changes in the centuries-old traditional rural economy Yakutia it proved viable and adaptable to the socio-political challenges of the twentieth century.

The value of historical and cultural background and regional characteristics and their influence on the nature of the investigated relations is revealed. The most important backgrounds include: geographical location of the specified area; multi-ethnic and multi-religious composition of the population; Islamic stratum of the Bulgar-Tatar culture; the policy of the Russian state in matters of religion; European influence on the development of culture (education in Russia, "Jadidism" in Muslim culture; tolerance as a condition of educational institutions; consistent transformation of Kazan in the cultural and educational center. It shows the development of inter-confessional relations in the region in terms of centuries of coexistence of Islam, Orthodoxy, paganism. The authors show the main tendencies of the policy of the Russian state that influenced the character of the development of inter-confessional and inter-ethnic relations in the region. The conclusion is made about the prospects of development of ethno-confessional relations in order to consolidate a modern society that is possible subject to the necessary balance of interests of all religious groups and cultural diversity support.

    Full Text Available Este artículo analiza la trayectoria de políticas coercitivas con las que el Estado argentino intentó inferir en la producción de sexualidades durante el siglo XX. La “violencia moral” incluyó prácticas de represión: códigos de faltas provinciales y razzias como formas de delimitación a homosexuales, prostitutas y pobres urbanos. Las mismas constituyeron un hilo de continuidad entre gobiernos civiles y regímenes castrenses. La premisa sostiene que ante la percepción de precarización de una identidad de la cultura nacional oficial, promovida por cambios sociales, demográficos, económicos y culturales en los albores del siglo, el Estado actuó progresivamente como catalizador de la reproducción directa de relaciones dominantes. La sensación de fragilidad de las condiciones que hacían perdurable una ciudadanía imaginada como heterosexual, blanca, masculina y capitalista se institucionalizó en un modo de concebir la moral que devino en políticas violentas. Partiendo de esta hipótesis se analizaran las formas especificas que asumieron estas políticas en el territorio urbano bonaerense. Con el fin de problematizar el vínculo entre Estado, sexualidades y violencias.

    Full Text Available The article is dedicated to the conceptualization of the innovations in the theories of T. Parsons at the turn of the XX-XXI centuries. It is stated the increased interest for structural functionalism in the development of sociological theory as well as in applied research. The article illustrates that the attempt of T. Parsons to create a system of categories enable to accept systematic integration of sociological science, explaining the existence of all the levels of the society and all the social forms in the process of movement of the matter, caused great interest among the scientists in the leading sociological centres of the world. The structurally-functionalist paradigm, associated with Parsons, was reflected in institutional imperatives of “ethnic science” by R. Merton, representation of science as a multilevel continuum, suggested by D. Alexander, in the conception/concept of “double contingency” by N. Luhmann, culture as a network of symbols by C. Geertz, the theory of communicative action by J. Habermas, in the theory of structuration by A. Giddens, the concept of the acting person by A. Touraine and etc.

    Mouse sex determination provides an attractive model to study how regulatory genetic networks and signaling pathways control cell specification and cell fate decisions. This study characterizes in detail the essential role played by the insulin receptor (INSR) and the IGF type I receptor (IGF1R) in adrenogenital development and primary sex determination. Constitutive ablation of insulin/IGF signaling pathway led to reduced proliferation rate of somatic progenitor cells in both XX and XY gonads prior to sex determination together with the downregulation of hundreds of genes associated with the adrenal, testicular, and ovarian genetic programs. These findings indicate that prior to sex determination somatic progenitors in Insr;Igf1r mutant gonads are not lineage primed and thus incapable of upregulating/repressing the male and female genetic programs required for cell fate restriction. In consequence, embryos lacking functional insulin/IGF signaling exhibit (i) complete agenesis of the adrenal cortex, (ii) embryonic XY gonadal sex reversal, with a delay of Sry upregulation and the subsequent failure of the testicular genetic program, and (iii) a delay in ovarian differentiation so that Insr;Igf1r mutant gonads, irrespective of genetic sex, remained in an extended undifferentiated state, before the ovarian differentiation program ultimately is initiated at around E16.5.

These are moderately-sized dictionaries published about 1930. For their respective authors (a German, a Pole, and a Lithuanian, Russian was not their native language, and yet they each mastered it wonderfully, having spent part of their lives in the Russian Empire and in the USSR. The dictionaries studied were compiled in a period of unprecedented growth in new Russian lexis. Lexical resources expanded rapidly due to violent socio-political changes and the new phenomena they brought about that needed to be named, as well as the concomitant, equally dynamic scientific and technical advances, which also caused a sub­stantial increase in new lexis. The level of difficulty in constructing a list of key words was increased by the lack of current Russian definition dictionaries at the time. The author has shown that the editors of the Russian-German and the Russian-Polish dictionaries, that appeared in Moscow, included abundant neologisms: the most variegated Sovietisms (e.g., агитпункт, cоциал-предатель, scientific and technical vocabulary (авиация, автомобиль, acronyms (нэп, Главрепертком, as well as borrowings from the national languages of the USSR (арык, аул.

    Full Text Available There is ample historical verification of 46,XX congenital adrenal hyperplasia (CAH patients being born with essentially male genitaliawhile outcome information is scant. Prior to glucocorticoid therapy, most patients died very young from adrenal insufficiency. Most available reports from laterchildhood, contain little information concerning sexual identity. Reports on older individuals lack adequate information about sexual identity and quality of life. The difficulty in assessing the relative impact of multiple dynamic environmental factors on the development of sexual identity, self- and body esteem and overall adjustment to life is clear. Nevertheless, it remains unclear whether those infants whose masculine genitalia at birth resulted in an initial male assignment would have enjoyed a better adult outcome had they been allowed to remain male rather than the female reassignment that most received. Further, one could ask whether a male sex of rearing should be considered in 46,XX CAH infants with male external genitalia. After reviewing available literature, we conclude that because those extremely virlized 46,XX CAH patients who were reared male with healthy social support demonstrated satisfactory levels of social and sexual function as adults a male sex assignment should be considered in these types of infants when social and cultural environment are supportive.

    In the normal population, loss of one of the sex chromosomes leading to monosomy (45,X) is a part of the aging process. In Turner syndrome (TS), the classic karyotype 45,X is found in up to 50% at birth, and others have a second cell line; mosaicism. The aim was to study if the chromosomal pattern in TS women changes over time. Fluorescence in situ hybridization was performed on buccal smear cells obtained twice, 10 years apart, from 42 women with TS aged 26-66 years (mean±standard deviation: 42.0±11.6). DNA probes specific for chromosomes X (DXZ1) and Y (DYZ3) were used and >100 cells were analyzed/patient. Nineteen women had monosomy (45,X) (<10% 46,XX), nine had 45,X/46,XX mosaicism, and 14 had iso, ring, or a marker chromosome at baseline. At 10 years, the percentage of diploid cells had increased in 29 of 42 women (69%), with an average increase of 5.7±13.0%. There was a positive correlation between age and % change in diploid 46,XX or 46,XY cells (r=0.38, p=0.023). This new finding might have relevance for the life expectancy in TS.

    Cells of a given type maintain a characteristic cell size to function efficiently in their ecological or organismal context. They achieve this through the regulation of growth rates or by actively sensing size and coupling this signal to cell division. We focus this review on potential size-sensing mechanisms, including geometric, external cue, and titration mechanisms. Mechanisms that titrate proteins against DNA are of particular interest because they are consistent with the robust correlation of DNA content and cell size. We review the literature, which suggests that titration mechanisms may underlie cell-size sensing in Xenopus embryos, budding yeast, and Escherichia coli, whereas alternative mechanisms may function in fission yeast.

    An account is given of the karyotypes of 29 species of medium sized Dytiscidae (Coleoptera). Of the 20 species of Agabus Leach, 1817, 18 have karyotypes comprising 21 pairs of autosomes and sex chromosomes which are either X0(♂) or XX (♀). These species are Agabus serricornis (Paykull, 1799), Agabus labiatus (Brahm, 1791), Agabus congener (Thunberg, 1794), Agabus lapponicus (Thomson, 1867), Agabus thomsoni (J. Sahlberg, 1871), Agabus confinis (Gyllenhal, 1808), Agabus sturmii (Gyllenhal, 1808), Agabus bipustulatus (Linnaeus, 1767), Agabus nevadensis Håkan Lindberg, 1939, Agabus wollastoni Sharp, 1882, Agabus melanarius Aubé, 1837, Agabus biguttatus (Olivier, 1795), Agabus binotatus Aubé, 1837, Agabus affinis (Paykull, 1798), Agabus unguicularis (Thomson, 1867), Agabus ramblae Millan & Ribera, 2001, Agabus conspersus (Marsham, 1802) and Agabus nebulosus (Forster, 1771). However two species, Agabus infuscatus Aubé, 1838 and Agabus adpressus Aubé, 1837, have developed a neo-XY system, with karyotypes comprising 21 pairs of autosomes and XY sex chromosomes (♂).

    One of the most important problems in designing an experiment or a survey is sample size determination and this book presents the currently available methodology. It includes both random sampling from standard probability distributions and from finite populations. Also discussed is sample size determination for estimating parameters in a Bayesian setting by considering the posterior distribution of the parameter and specifying the necessary requirements. The determination of the sample size is considered for ranking and selection problems as well as for the design of clinical trials. Appropria

    The common failure to include an estimation of sample size in grant proposals imposes a major handicap on applicants, particularly for those proposing work in any aspect of research in the health services. Members of research committees need evidence that a study is of adequate size for there to be a reasonable chance of a clear answer at the end. A simple illustrated explanation of the concepts in determining sample size should encourage the faint hearted to pay more attention to this increasingly important aspect of grantsmanship.

  8. Genome size evolution: sizing mammalian genomes.

    The study of genome size (GS) and its variation is so fascinating to the scientific community because it constitutes the link between the present-day analytical and molecular studies of the genome and the old trunk of the holistic and synthetic view of the genome. The GS of several taxa vary over a broad range and do not correlate with the complexity of the organisms (the C-value paradox). However, the biology of transposable elements has let us reach a satisfactory view of the molecular mechanisms that give rise to GS variation and novelties, providing a less perplexing view of the significance of the GS (C-enigma). The knowledge of the composition and structure of a genome is a pre-requisite for trying to understand the evolution of the main genome signature: its size. The radiation of mammals provides an approximately 180-million-year test case for theories of how GS evolves. It has been found from data-mining GS databases that GS is a useful cyto-taxonomical instrument at the level of orders/superorders, providing genomic signatures characterizing Monotremata, Marsupialia, Afrotheria, Xenarthra, Laurasiatheria, and Euarchontoglires. A hypothetical ancestral mammalian-like GS of 2.9-3.7 pg has been suggested. This value appears compatible with the average values calculated for the high systematic levels of the extant Monotremata (∼2.97 pg) and Marsupialia (∼4.07 pg), suggesting invasion of mobile DNA elements concurrently with the separation of the older clades of Afrotheria (∼5.5 pg) and Xenarthra (∼4.5 pg) with larger GS, leaving the Euarchontoglires (∼3.4 pg) and Laurasiatheria (∼2.8 pg) genomes with fewer transposable elements. However, the paucity of GS data (546 mammalian species sized from 5,488 living species) for species, genera, and families calls for caution. Considering that mammalian species may be vanished even before they are known, GS data are sorely needed to phenotype the effects brought about by their variation and to validate any

It is shown that high moral ideals and a desire to help people in need be useful to its edge and to society in general – describe the ideas, common in the student's environment at the turn of XIX – XX centuries. Based on the analysis of archival materials and scientific literature, it was found that the students showed during this period, an increased desire to participate in social and cultural life of Siberia and the whole country. However, this participation in different ways manifested in the minds and actions of young people. Some students, actively engage in the cultural life of the region, entered in the companies involved in charity work, academic research, literary and theatrical art, medicine, advanced study of philosophy, technical processes, etc. At universities created various thematic interest groups, on a territorial basis – numerous fraternities, a nobility of purpose in the form of moral and material support of their members. However, some Siberian students in their own way understood his own mission in social processes, including under the form of participation in legal societies, clubs or fraternities in the activities of political and campaign focus, in the meetings discussing ideas about the possibilities of revolution, as expected, from their point of view, progress and prosperity in case of their implementation. Also in this period, there are illegal organizations that engage some students of Siberian universities. The activities of such organizations is highly political in nature.

    Full Text Available The article elaborates upon organization and stages of pilgrimage of West Siberian residents to Palestine at the end of XIX — beginning of XX century. The author makes an attempt to show the motives behind the pilgrimage, as well as organizational and household challenges. The article outlines some details of Siberians’ stay in Russian courtyards in Jerusalem and describes fi nancial situation enabling the pilgrims to travel to Palestine and back. The study is based on personal sources describing the impressions and experience the Western Siberians had when visiting the Holy Land. The author concludes that Russian pilgrims would usually spend about half a month at the Russian courtyards and that the accommodation, catering and living conditions of their stay were quite adequate at the beginning of the XXth century. It is noted that the number of pilgrims from West Siberian provinces at that period reached several dozen people a year. Social and age compound of pilgrims is described. The article outlines local peculiarities of pilgrims, such the predominance of men, including a small number of indigenous residents of Siberia. It is noted that the vast number of pilgrims were farmers and elderly people. The article shows some examples of pilgrims sharing their impressions and spiritual experience with family members, relatives, friends and neighbors after returning to homeland. The paper demonstrates the contribution of the Imperial Orthodox Palestine Society to improvement of pilgrimage routes and services to pilgrims during the above mentioned timeframe. Despite the fact that those the pilgrimages didn’t become a widespread phenomenon, they seized to be something of an extraordinary nature.

The main features of the organization of an entry are considered. There are a chronological ranging of examples in obligatory “zone of contexts”, which is allowing to build history of each separate word; a filling of facultative “meaning zone” with data on peculiarities of each lexeme semantics, of the stylistic accent of lexemes, etc., about variant connections with other units of the Dictionary. Entries from different volumes of the edition are used as illustrations. It is noted also, that already at an initial plan of the Dictionary there was an idea of its improvement, therefore work on the project is development and specification of the different parts of its concept today. Thus, the information on phraseological manifestations of the word was embedded into the last of the published volumes, by means of a special mark. Material of the description and interests of the user of the Dictionary prompted expediency of such step (for example, it is important to explain to modern reader that the combination of words ‘not to put okhulka on a hand’, which is found in article Okhulka ‘abuse’, means ‘not to miss the benefit’. The article also discusses the experience of use of the Dictionary data in other lexicographic projects and in various linguistic researches.

Abstract: This article deals with the disappearance, replacement or transformation of particular neoclassical altarpieces in Seville, city and province, during the twentieth century. It also gives the reasons behind these changes. They are almost always due to liturgical adaptations, the ups and downs of fashion and the individual tastes of those promoting or commissioning particular works of art. Our aim is to highlight the more important cases to date and, as a result, to argue for the conservation and protection of these architectural wooden works of art; they are normally located in the interior of churches and shrines and are furnishings which form part and parcel of the rich cultural patrimony and identity of our geographical landscape.

    Full Text Available El objetivo de este trabajo es establecer cuáles eran los beneficios sociales otorgados por los propietarios de ingenios en sus fábricas y qué relación tenían estos beneficios con las concepciones que tenían los industriales en torno a la “cuestión social” en un período que se extiende desde fines del siglo XIX hasta principios del siglo XX. La actividad azucarera demostró tempranamente la necesidad de contar con una mano de obra disciplinada y para lograrlo fue importante el respaldo de los poderes públicos a través del diseño de un marco legal que respaldaba las estrategias desplegadas por las fábricas y cañeros para asegurar ese objetivo. A la par de esta legislación coercitiva, los industriales tucumanos otorgaban también una serie de beneficios como vivienda, seguros, asistencia médica primaria y educación. Es decir, que desde temprano las prácticas coactivas se combinaron con asistencialismo, y resulta de interés ofrecer alguna clave explicativa del sentido de estas acciones. Las diferencias existentes entre los ingenios, se traducían en marcadas desigualdades en los beneficios que recibían los trabajadores, pero sin duda era la pertenencia a la fábrica en calidad de trabajador lo que aseguraba la vivienda, la ración y la atención médica y por lo tanto pérdida del puesto laboral no sólo implicaba la pérdida del salario sino también del lugar de residencia y el acceso a los beneficios.

Partimos da hipótese de que a postura do relator fazia parte de uma extensa ação disciplinadora de controle da cidade, à qual a imprensa não escapava. Tal ação disciplinadora estava pautada pelas teorias racistas e deterministas de matriz européia e articulava diversas instâncias do poder. Aplicadas de modo particular ao contexto brasileiro em razão do passado escravista, a tentativa de ordenamento da cidade agrega o racismo de cor ao de classe, redimensionado no novo contexto republicano.This article is about representations of the city of São Paulo made by the periodical O Estado de S. Paulo in 1910 and analyses a case of censorship towards the media, through a Report of Justice, related to the divulgation of fait divers style suicide cases in the period of transition between the 19th and the 20th centuries. We start from the following hypothesis: the position of the author of the Report was influenced by an extensive disciplinary action set up to control the city and that targeted also the media. Such disciplinary action was based on racist and determinist theories, of european matrix, and articulated various levels of power. Applied to this particular Brazilian context due to its legacy of slavery, the attempt to put order in the city joins the racism to social exclusion, adapted to the New Republican era.

    Aim: This study evaluates the impacts of using different evaluation criteria on gamma pass rates in two commercially available QA methods employed for the verification of VMAT plans using different hypothetical planning target volumes (PTVs) and anatomical regions. Introduction: Volumetric modulated arc therapy (VMAT) is a widely accepted technique to deliver highly conformal treatment in a very efficient manner. As their level of complexity is high in comparison to intensity-modulated radiotherapy (IMRT), the implementation of stringent quality assurance (QA) before treatment delivery is of paramount importance. Material and Methods: Two sets of VMAT plans were generated using Eclipse planning systems, one with five different complex hypothetical three-dimensional PTVs and one including three anatomical regions. The verification of these plans was performed using a MatriXX ionization chamber array embedded inside a MultiCube phantom and a Varian EPID dosimetric system attached to a Clinac iX. The plans were evaluated based on the 3%/3 mm, 2%/2 mm, and 1%/1 mm global gamma criteria and with three low-dose threshold values (0%, 10%, and 20%). Results: The gamma pass rates were above 95% in all VMAT plans, when the 3%/3mm gamma criterion was used and no threshold was applied. In both systems, the pass rates decreased as the criteria become stricter. Higher pass rates were observed when no threshold was applied and they tended to decrease for 10% and 20% thresholds. Conclusion: The results confirm the suitability of the equipments used and the validity of the plans. The study also confirmed that the threshold settings greatly affect the gamma pass rates, especially for lower gamma criteria.

    2005-01-15

    The belief is widespread that studies are unethical if their sample size is not large enough to ensure adequate power. The authors examine how sample size influences the balance that determines the ethical acceptability of a study: the balance between the burdens that participants accept and the clinical or scientific value that a study can be expected to produce. The average projected burden per participant remains constant as the sample size increases, but the projected study value does not increase as rapidly as the sample size if it is assumed to be proportional to power or inversely proportional to confidence interval width. This implies that the value per participant declines as the sample size increases and that smaller studies therefore have more favorable ratios of projected value to participant burden. The ethical treatment of study participants therefore does not require consideration of whether study power is less than the conventional goal of 80% or 90%. Lower power does not make a study unethical. The analysis addresses only ethical acceptability, not optimality; large studies may be desirable for other than ethical reasons.

Consideraram-se as quatro variantes a seguir para a análise do fenômeno: cl V1 V2 (se deve fazer; V1-cl V2 (deve-se fazer; V1 cl V2 (deve se fazer; e V1 V2-cl (deve fazer-se, com base em dados coletados em anúncios, editoriais e notícias, sendo a maioria do corpus do Projeto Varport. Acredita-se que a variante considerada inovadora (V1 cl V2 não seria produzida pelos europeus nos dois séculos em questão, sendo realizada apenas na escrita brasileira, significativamente no século XX. Os resultados apontam que, no século XIX, o Brasil tende a seguir, com alguma variação, o padrão lusitano da colocação pronominal, que era o da próclise a V1, diante de elementos proclisadores em contextos não iniciais, e da ênclise a V1/V2 na ausência desses possíveis proclisadores. A partir do século XX, as produções do Brasil apresentam, de forma crescente, dados de próclise a V2, o que não ocorre em Portugal, que tende a distribuir equilibradamente as variantes pré e pós complexo verbal, sempre vinculadas às restrições estruturais, como as referentes aos tipos de proclisador, de clítico e de complexo verbal. Os resultados do fim do século XX sugerem que a escrita brasileira passa a incorporar, cada vez mais, as mudanças linguísticas já implementadas na fala vernacular.

    Hypospadias is rarely reported in dogs. In this study we pre-sent 2 novel cases of this disorder of sexual development and, in addition, a case of hereditary sex reversal in a female with an enlarged clitoris. The first case was a male Moscow watchdog with a normal karyotype (78,XY) and the presence of the SRY gene. In this dog, perineal hypospadias, bilateral inguinal cryptorchidism and testes were observed. The second case, representing the Cocker spaniel breed, had a small penis with a hypospadic orifice of the urethra, bilateral cryptorchidism, testis and a rudimentary gonad inside an ovarian bursa, a normal female karyotype (78,XX) and a lack of the SRY gene. This animal was classified as a compound sex reversal (78,XX, SRY-negative) with the hypospadias syndrome. The third case was a Cocker spaniel female with an enlarged clitoris and internally located ovotestes. Cytogenetic and molecular analyses revealed a normal female karyotype (78,XX) and a lack of the SRY gene, while histology of the gonads showed an ovotesticular structure. This case was classified as a typical hereditary sex reversal syndrome (78,XX, SRY-negative). Molecular studies were focused on coding sequences of the SRY gene (case 1) and 2 candidates for monogenic hypospadias, namely MAMLD1 (mastermind-like domain containing 1) and SRD5A2 (steroid-5-alpha-reductase, alpha polypeptide 2). Sequencing of the entire SRY gene, including 5'- and 3'-flanking regions, did not reveal any mutation. The entire coding sequence of MAMLD1 and SRD5A2 was analyzed in all the intersexes, as well as in 4 phenotypically normal control dogs (3 females and 1 male). In MAMLD1 2 SNPs, including 1 missense substitution in exon 1 (c.128A>G, Asp43Ser), were identified, whereas in SRD5A2 7 polymorphisms, including 1 missense SNP (c.358G>A, Ala120Thr), were found. None of the identified polymorphisms cosegregated with the intersexual phenotype, thus, we cannot confirm that hypospadias may be associated with polymorphism

    Full Text Available Los personajes masculinos fueron los protagonistas principales de Marvel Comics durante el siglo XX. Dichos personajes mostraban algunas características de forma persistente que ayudaron a fraguar un mito de la masculinidad. A pesar de esto, dicho mito evolucionó a partir de 1961, ampliando los estrechos márgenes de la masculinidad. Los objetivos de este artículo son, en primer lugar, entender cuál fue el mensaje que lanzaba dicho mito, cómo afectaba a los hombres en función de si eran jóvenes, adultos o ancianos, y en qué modo cambió con el paso del tiempo. En segundo lugar, nos proponemos entender las transformaciones sociales, económicas y productivas que ayudaron a desarrollar un nuevo mito de la masculinidad. Para lograr esto, vamos a estudiar algo más de un centenar de publicaciones de Marvel Comics publicadas entre los años 1940 y 2000, analizando desde la perspectiva de los Estudios Culturales los arquetipos presentados. Entre las conclusiones a las que hemos llegado cabe destacar la existencia de un modelo patriarcal de masculinidad que sobrevivió sin problemas hasta 1960 debido a una mezcla de factores políticos, económicos y productivos, si bien los importantes cambios en la producción de cómics experimentada en las oficinas de Marvel durante 1961 condujeron a que dicho modelo dejase de ser el único existente; a esto ayudaron en los años sesenta y setenta los importantes problemas políticos, económicos y sociales que sacudieron los Estados Unidos. A pesar de todo ello, no podemos afirmar que el mito de la masculinidad evolucionara de una manera irreversible e imparable, antes al contrario, existió una relación dialéctica entre un nuevo y un viejo mito de masculinidad.

Francia y su especial influjo en aspectos políticos y administrativos proporciona los principios que atraen a muchos protagonistas de la educación española durante el primer tercio del XX; Alemania, junto a la sistematización de su pensamiento ofrece una pedagogía propiciadora de un socialismo humanista y una ética nueva; el modelo de formación de minorías que caracteriza la pedagogía inglesa fascina a liberales y conservadores. La influencia de la Rusia soviética es visible sobre todo durante la República en guerra, un momento éste en el que, y hasta mediados del siglo, la educación del régimen de Franco conoce también el peso de la pedagogía nazi sobre todo en la organización de la juventud y en experiencias de asistencia social, y de la pedagogía del fascismo italiano en la política educativa del primer franquismo. A partir de entonces la influencia en la política educativa española corresponde a los organismos internacionales.ABSTRACT: The influence European macro models have upon Spanish educational policy, is studied in this article. France and its special influence in political and administrative aspects, provides the principles which attract many protagonists of the Spanish education during the first third of the 20th century. Germany, with the systematisation of its thoughts, offers a pedagogy that propitiates a humanist socialism and a new ethic. The model of education of minorities, characteristic of English pedagogy, fascinates both liberals and conservatives. The influence of the Soviet Russia is visible above all during the Republic in times of the Civil War, moment in which, and until about the middle of the 20th century, Franco’s regime education also knows the weight of nazi pedagogy, specially in youth organisations and in social work experiences, and the Italian’s fascism

Special attention is given to the most peculiar aspects of this chase, such as its legislation, the massive killing of dolphins in Pontevedra, or the chasing runs by navy patrolboats in the river estuaries of Galicia. Finally, after mentioning the attempts at establishing a dolphin industry in the 18th and 19thcenturies, a study is made of the most ambitious plan undertaken in the 20th century to secure the involvement of the whaling industry into this activity. The study also refers to the situation of this activity in the rest of Spain both for its direct relationship with and as a precedent for the Galician case, and makes a comparison between them.

    Se realiza un estudio histórico sobre la problemática interacción entre el hombre como pescador y los definidos en Galicia, con la consiguiente persecución de los cetáceos, a los cuales culpan de la escasez de pescado, como depredadores y ahuyentadores de los bancos de peces lejos de la costa, además de ocasionar destrozos en las redes. Se presta especial atención a los aspectos más peculiares de su persecución, como la legislación, los consejos del ilustrado fray Martín Sarmiento, las corridas de arroaces en Pontevedra o las batidas por parte de las patrulleras de la Armada dentro de las rías.

    Full Text Available El análisis del rol desempeñado por las redes eclesiásticas en las relaciones centro-periferia, en un Estado como el español, caracterizado por los debates suscitados en torno a este binomio durante una buena parte del siglo XX, nos adentra en la dimensión alcanzada por la cuestión territorial en la administración de las diócesis y provincias eclesiásticas, la promoción vocacional del clero y la selección de sus más cualificados dirigentes. La acción y el discurso de los órganos pontificios y las diversas instituciones de la Iglesia en España incidirán no sólo en el desarrollo de prácticas pastorales más atentas a las peculiaridades culturales y sociales propias de cada Iglesia local, sino también en la singular trayectoria de los diversos proyectos de construcción nacional que compitieron durante la pasada centuria.      Palabras clave: Vaticano, España, diócesis, provincia eclesiástica, regionalismo, nacionalismo.  _____________ Abstract: The analysis of the role played by the church networks in center-periphery relations in a state such as Spain, characterized by the discussions on this pair at least for most of the 20th century, takes us into the dimension reached by the territorial issue in the administration of dioceses and ecclesiastical provinces, vocational promotion of the clergy and the selection of its most qualified leaders. The action and discourse of the pontifical bodies and several institutions of the Church in Spain will impact not only in pastoral practices more alive to the social and cultural peculiarities, but also in the unique path of various nation-building projects which competed during the last century.      Keywords: Vatican, Spain, dioceses, ecclesiastical provinces, regionalism, nationalism.

La hipertensión arterial, como factor de riesgo, la topografía inferior del infarto y al fallo de bomba, como complicación, fueron los más frecuentemente encontrados.

  17. Cartões postais paulistanos da virada do século XX: problematizando a São Paulo "moderna"

    Full Text Available Considerando que os cartões postais dotados de reproduções fotográficas começam a difundir-se em São Paulo em fins do século XIX, o objetivo deste artigo é analisar se, enquanto documentação iconográfica do contexto paulistano daquele momento, este material teria veiculado, para a sociedade da época, basicamente representações visuais de uma cidade moderna por excelência - e portanto distanciada dos referenciais culturais rurais e escravocratas originados em seu passado colonial. A fim de responder esta questão, explorei, em imagens postais da virada do século XX que tematizam o bonde nas ruas aparentemente mais modernas da área central da cidade, a relação signo-referente por meio de uma contextualização do dia-a-dia vivenciado pelos transeuntes nas ruas retratadas. O estudo revelou que a associação comumente feita entre as vistas urbanas paulistanas da virada do século e a imagem da São Paulo "moderna" não dá conta da lógica que norteia a concepção que a própria sociedade teria tido a respeito das fotografias, em seu tempo.Based on the fact that photographic postcards start to be edited in São Paulo at the end of the 19th century, this article analyses if the cards, as modern iconographic documents in the paulistano past, basically propagated, to the society of that time, visual representations of a modern city par excellence - thus free from rural and slavish cultural references, which were brought about in its colonial past. In order to answer this question I evaluated the relation between sign and referent in postcard photographs of tramways in downtown São Paulo in the turn of the 20th century by contextualizing the day-by-day experienced by pedestrians in the photographed streets . The study reveals that the common association between turn-of-the-century São Paulo urban photographs and the image of a "modern" city is not a sufficient explanation if the aim is the comprehension of that society's own

    2009-03-01

    Full Text Available El fenómeno musical en la edad contemporánea fue una expresión singular de un modo de trabar las relaciones sociales y un mecanismo de ejercicio de poder por parte de la burguesía, de la misma forma que había sucedido en épocas más remotas con las grandes monarquías absolutas o con la Iglesia de Roma. A su vez, en ocasiones, fue un elemento revolucionario, crítico con el orden establecido y agente activo en el cambio político y social. De esta forma, la producción musical de cada período histórico puede reflejar valores de la clase dominante y argumentos legitimadores de su poder. Asimismo, paralelamente a esto, pueden localizarse obras en las que, por el contrario, se realiza una crítica al sistema, convirtiéndose en preconizadoras o colaboradoras de grandes cambios político-sociales. No por obvio debemos dejar de recordar que la actividad cultural desarrollada por los grandes creadores a lo largo de la historia es un reflejo de su tiempo, de la sociedad de la que ha surgido la obra. Concretamente, en este artículo se estudian las posibilidades que el fenómeno musical tiene como elemento de análisis del siglo XX.____________________ABSTRACT:The contemporary musical development has uniquely expressed a form of weaving together social relationships, and has also represented a type of practice with which the world powers have exerted their influences, in the same way as the absolute monarchies or the Roman Church did in far-off times. But in some occasions, it has also been a revolutionary component, critical with the established system and determinant in the political and social change. In this way the musical production in each historical period can mirror the values of the governing class and their reasons to remain in power. At the same time as well, there are some works which on the other hand criticize the established system, advocating and taking part in the main socio-political changes. It may seem obvious but we shouldn

    Full Text Available Developing of methods of measuring the radii of nuclei in their highly excited states led to observation of those with dimensions enhanced and, probably, diminished in comparison with the corresponding ground states. Experimental data including very recent ones demonstrating that such “size isomers” belong to two groups: excited states having neutron halos (in 13C, 11Be and 9Be and some specific cluster states (in 12C, 13C and 11B, are discussed.

  3. Aerosol mobility size spectrometer

    Science.gov (United States)

    Wang, Jian; Kulkarni, Pramod

    2007-11-20

    A device for measuring aerosol size distribution within a sample containing aerosol particles. The device generally includes a spectrometer housing defining an interior chamber and a camera for recording aerosol size streams exiting the chamber. The housing includes an inlet for introducing a flow medium into the chamber in a flow direction, an aerosol injection port adjacent the inlet for introducing a charged aerosol sample into the chamber, a separation section for applying an electric field to the aerosol sample across the flow direction and an outlet opposite the inlet. In the separation section, the aerosol sample becomes entrained in the flow medium and the aerosol particles within the aerosol sample are separated by size into a plurality of aerosol flow streams under the influence of the electric field. The camera is disposed adjacent the housing outlet for optically detecting a relative position of at least one aerosol flow stream exiting the outlet and for optically detecting the number of aerosol particles within the at least one aerosol flow stream.

    Full Text Available Los encinares actuales de Quercus ilex subsp. ballota (Desf. Samp. en el ámbito mediterráneo de la Península Ibérica y en el amplio espacio de las llanuras y montañas de la Comunidad autónoma de Castilla y León, son en gran parte resultado de la intervención humana en el paisaje vegetal. Concretamente, se presentan testimonios de varias repoblaciones desde el siglo XVI hasta la primera mitad del siglo XX, pasando por la época de esplendor documental y de actividad real de mediados del siglo XVIII. Además, a lo largo del siglo XX se constata que algunos encinares, como masa forestal «pura», son consecuencia de «protecciones» llevadas a cabo por grupos sociales rurales. Los encinares, por tanto, no constituyen ni el bosque primigenio ni el bosque autóctono por excelencia del paisaje vegetal ibérico.

    In this study, the annual cycle of the gonadal steroids testosterone (T), 11-ketotestosterone (11-KT), 17β-estradiol (E2) and 17α, 20β-dihydroxy-4-pregnen-3-one (DHP) was determined using radioimmunoassay and then compared for two populations of rainbow trout, XX diploid females (n = 40) and XXX triploid females (n = 15). In females, E2 and DHP levels were found to be significantly related to body weight (r = 0.22513; p 0.001, respectively). In this group, E2 concentrations peaked in November (25.05 ng/ml), while maximum DHP levels, only measurable from October to April, were attained in February (64.14 ng/ml). No significant differences in hormone ranges related to egg output ability were observed. Finally, sex steroid concentrations were low in the triploid female XXX fish compared to the female XX population. Nevertheless, maximum T (33.85 ng/ml) and 11-KT (32.35 ng/ml) levels were recorded in January, for XXX. The levels for these two hormones are relatively high and are also significantly associated (r = 0.8430; p < 0.0001). Diploid females showed significantly higher levels of E2 than triploids over the 12-month study period. The female triploid fish produced the lowest steroid hormone levels, such that these would be the most suitable for human consumption. © 2012 Blackwell Verlag GmbH.

    Full Text Available En el último tercio del siglo XX los municipios de Simojovel y Huitiupán, ubicados en el norte de Chiapas, transitaron de una dinámica dominada por haciendas y ranchos (llamadas fincas en general a otra de comunidades campesinas. La transformación de la estructura agraria gene- ró modificaciones significativas en otros ámbitos; una de éstas ocurrió en el espacio doméstico o familiar. Para entender estos cambios daré cuenta de algunos tipos de familia conformados en la zona de estudio bajo la di- námica impuesta por las fincas establecidas entre mediados del siglo XIX y principios del XX. Sostengo que este proceso estaba conectado con las des- iguales relaciones creadas entre patrones y trabajadores. Después pasaré a reflexionar sobre ciertos cambios y continuidades en la institución familiar al ser destruidas las fincas y la figura del patrón, pero sin ser cuestionada la autoridad masculina, y constituirse las nuevas comunidades campesinas vinculadas a diversos proyectos políticos. Por último, delinearé apenas al- gunas de las repercusiones en la zona de los acelerados cambios del orden mundial y nacional, producidos a partir del decenio de 1970.

    Full Text Available Desde el siglo XIX, con la formación de los Estados nacionales en Latinoamérica, se han promovido proyectos integracionistas aún no concluidos. Actualmente, se resalta la necesidad de la integración entre países en distintos aspectos: económico, político, militar, diplomático. El propósito de este artículo es exponer las razones por las cuales el "panamericanismo" impuesto por los Estados Unidos se convirtió en el principal obstáculo para la consolidación de un verdadero proyecto de integración latinoamericano durante la primera mitad del siglo XX. Finalmente, después de realizar un recorrido por distintos intentos de integración durante la segunda mitad del siglo XX (observando las dificultades que ha tenido históricamente la comunidad regional, se pretende analizar la experiencia del Mercosur como el más consolidado proyecto de integración latinoamericano vigente en los comienzos del siglo XXI, en el ámbito económico e, incluso, político.

    2010-12-01

    Full Text Available Este artículo busca, mediante un análisis comparativo del espacio público y la vivienda de la élite de Bogotá en tres momentos diferentes del siglo XX, generar un proceso de reflexión acerca de la construcción de la identidad local o “bogotanidad”, entendiendo que en los espacios públicos y privados se refleja la estructura jerárquica, social y de género. Las estructuras físicas de la ciudad y de la casa, al igual que sus usos, se analizan como reflejo de la construcción identitaria local, a partir del marco teórico establecido por Michael Billig y Catherine Palmer. Se puede concluir que durante el siglo XX las mujeres de élite bogotanas contribuyeron desde lo “banal” a la creación de nuevos modelos sociales apropiados a la identidad de la ciudad, que permitieron cambios fundamentales reflejados, sobre todo en la vivienda y en la construcción de la intimidad.

    Full Text Available La caza costera tradicional de ballenas o “pesca de ballenas” se inicia en la zona de Talcahuano en la primera mitad del siglo XIX y luego se extiende hacia el sur de Chile, llegando hasta la Isla Grande de Chiloé. En este trabajo nos interesa escribir una etnografía de la caza costera en Tumbes e isla Santa María, denominada en la literatura de la época “pesca de ballenas”. Los datos sobre estas operaciones provienen de una serie de informes escritos a comienzos del siglo XX, complementados con datos provenientes de revisiones documentales administrativas, de búsquedas en diarios locales y de conversaciones con personas que conocieron el oficio de primera mano. La integración de estos datos permite escribir un relato plausible sobre la caza de ballenas en el centro sur de Chile en los comienzos del siglo XX, considerando que se trata de “un evento del pasado”.

  13. Design of new secreted phospholipase A2 inhibitors based on docking calculations by modifying the pharmacophore segments of the FPL67047XX inhibitor

    Docking calculations that allow the estimation of the binding energy of small ligands in the GIIA sPLA2 active site were used in a structure-based design protocol. Four GIIA sPLA2 inhibitors co-crystallised with the enzyme, were used for examining the enzyme active site and for testing the FlexX in SYBYL 6.8 molecular docking program to reproduce the crystallographic experimental data. The FPL67047XX inhibitor was chosen as a prototype structure for applying free energy perturbation (FEP) studies. Structural modifications of the initial structure of the FPL67047XX inhibitor (IC50 0.013 μM) were performed in an effort to optimise the interactions in the GIIA sPLA2 active site. The structural modifications were based on: (1) the exploration of absolute configuration (i.e. comparison of the binding score of ( R)- and ( S)-enantiomers); (2) bioisosterism (i.e. replacement of the carboxylate group with the bioisosteric sulphonate and phosphonate groups); (3) insertion of substituents that fit better in the active site. The generated new structures exhibited higher binding energy. Such structures may spark off the interest of medicinal chemists for synthesizing potentially more active GIIA sPLA2 inhibitors.

    Full Text Available No final do século XIX e início do século XX, imigrantes e descendentes de imigrantes alemães radicados no Sul do Brasil passaram a promover a defesa da ideologia da germanidade ou do Deutschtum. A defesa dessa ideologia, que ao longo do tempo teve intensidade variada, despertou reações por parte de intelectuais e de homens do governo brasileiro, que estavam empenhados na construção do estado e da identidade nacional. Essas reações se mostraram mais acentuadas e notadas durante a Primeira e a Segunda guerras mundiais e deram origem ao mito do “perigo alemão”. O “perigo alemão” consistiu em um real ou hipotético patrocínio, por parte do imperialismo germânico, de uma secessão de territórios do Brasil Meridional, que deveriam ficar como área de influência econômica ou de dominação direta da Alemanha. Neste trabalho, objetiva-se enfocar como o alemanismo e o perigo alemão aparecem em algumas obras de intelectuais brasileiros na primeira metade do século XX. Silvio Romero, Graça Aranha, Vianna Moog e Bayard Mércio são os principais autores retratados.

  18. Multimodal Raindrop Size Distributions.

    Sauvageot, Henri; Koffi, Manlandon

    2000-08-01

    The raindrop size distributions (DSDs) observed over a short span usually have an erratic shape, with several relative maxima. This multimodal structure is studied from disdrometer data acquired in tropical and midlatitude areas. It is shown that some modes of DSDs have a persistence larger than several minutes and can be spotted from one DSD to the next one as they migrate through the size classes. It is demonstrated that Nm, the number of modes of DSDs, for diameter larger than 2 mm, is not related to the mean rain rate but depends on the rain-rate fluctuations. Statistical evidence of such a relation is given. The spread of DSDs is found to be dependent on its multimodal structure, that is, on Nm. The large values of Nm are associated with low values of slope and intercept N0 of the fitted exponential distribution.In order to explain the dependence of the DSD shape on Nm, a conceptual model is proposed in which the modes are interpreted as resulting from an overlapping of rain shafts. The associated DSD is termed a synthetic drop size distribution (SDSD). It is shown that the overlapping of rain shafts generated from a sequence of rain cells of increasing intensity, such as observed at the leading edge of a convective system, results in undersloping SDSDs. In the reverse configuration, that is, with a sequence of rain cells with decreasing intensity, such as observed at the ending edge of a convective system, it results in oversloping SDSDs. Observations in agreement with these conclusions are presented. The readability of the modal structure of the DSDs depends on several factors in such a way that an apparent multimodal structure is not necessary for a DSD to be an SDSD. It is suggested that most of the DSDs observed at the ground are synthetic DSDs.

    Cell size is an important adaptive trait that influences nearly all aspects of cellular physiology. Despite extensive characterization of the cell-cycle regulatory network, the molecular mechanisms coupling cell growth to division, and thereby controlling cell size, have remained elusive. Recent work in yeast has reinvigorated the size control field and suggested provocative mechanisms for the distinct functions of setting and sensing cell size. Further examination of size-sensing models based on spatial gradients and molecular titration, coupled with elucidation of the pathways responsible for nutrient-modulated target size, may reveal the fundamental principles of eukaryotic cell size control.

    We report on a 23-year-old man with craniofacial findings of the holoprosencephaly spectrum disorder (microcephaly, hypotelorism, depressed nasal bridge, single median maxillary central incisor), fusion of C2-C3 vertebrae, intellectual disability, and severe sleep apnea. Chromosome analysis of blood lymphocytes showed 75% ring (18) cells and 25% normal cells, karyotype mos 46,XY,r(18)(::p11→q21::)[75]/46,XY[25]. His mother was phenotypically normal except for a double ureter and bifid renal pelvis as in his son. She had a supernumerary ring (18) in 10% of blood lymphocytes, karyotype mos 47,XX,+r(18)(::p11→q21::)[10]/46,XX[90]. Familial ring (18) is a rare cytogenetic abnormality. This is the first report of a mother with a supernumerary ring (18) and a son with ring (18) mosaicism. Interestingly, the son showed a true mosaicism (mixoploidy) of ring (18) and normal cells. The mother's 46,XX cells could be easily explained by mitotic instability and ring loss during cell division. However, the coexistence of ring (18) and normal cells in the son is unusual. Possibly, during early postzygotic divisions of a 47,XY,+r(18) zygote, two (possibly subsequent) genetic events could have occurred, one when one normal chromosome 18 was lost (resulting in a cell line with ring 18), and one when the ring 18 was lost (resulting in a cell line without ring, "escape to normal").

    Traditionally, the perceived size of negative afterimages has been examined in relation to E. Emmert's law (1881), a size-distance equation that states that changes in perceived size of an afterimage are a function of the distance of the surface on which it is projected. Here, we present evidence that the size of an afterimage is also modulated by its surrounding context. We employed a new version of the Ebbinghaus-Titchener illusion with flickering surrounding stimuli and a static inner targ...

  9. Sexual Dimorphism of Body Size Is Controlled by Dosage of the X-Chromosomal Gene Myc and by the Sex-Determining Gene tra in Drosophila.

    Science.gov (United States)

    Mathews, Kristina Wehr; Cavegn, Margrith; Zwicky, Monica

    2017-03-01

    Drosophila females are larger than males. In this article, we describe how X-chromosome dosage drives sexual dimorphism of body size through two means: first, through unbalanced expression of a key X-linked growth-regulating gene, and second, through female-specific activation of the sex-determination pathway. X-chromosome dosage determines phenotypic sex by regulating the genes of the sex-determining pathway. In the presence of two sets of X-chromosome signal elements (XSEs), Sex-lethal (Sxl) is activated in female (XX) but not male (XY) animals. Sxl activates transformer (tra), a gene that encodes a splicing factor essential for female-specific development. It has previously been shown that null mutations in the tra gene result in only a partial reduction of body size of XX animals, which shows that other factors must contribute to size determination. We tested whether X dosage directly affects animal size by analyzing males with duplications of X-chromosomal segments. Upon tiling across the X chromosome, we found four duplications that increase male size by >9%. Within these, we identified several genes that promote growth as a result of duplication. Only one of these, Myc, was found not to be dosage compensated. Together, our results indicate that both Myc dosage and tra expression play crucial roles in determining sex-specific size in Drosophila larvae and adult tissue. Since Myc also acts as an XSE that contributes to tra activation in early development, a double dose of Myc in females serves at least twice in development to promote sexual size dimorphism.

    Stochik, A M; Zatravkin, S N

    2015-01-01

    The article describes the system of conceptions about subject of investigation in medicine and methods of research activities of physicians well-established by early 70s of XIX century. It is postulated that in the middle of 1870s in medicine occurred an objective need of entirely different from before vision of investigated reality, development and implementation of fundamentally new methodological approaches to its studying that by-turn initiated global scientific revolution in medicine of the last quarter of XIX-first half of XX centuries. It is substantiated that need of new vision of investigated reality became first of all a consequence of profound intra-disciplinary crisis related to awareness of fallibility of existed ideas of human organism and its vital activity. The second cause is two "paradigm inoculations" from biology which resulted in forced acceptance by physicians the extreme incompleteness and fallacy of their previous views concerning environment and essence of its effect on human organism.

Por último, sostendré que la manifestación política de este fondo aporético–sobre el cual hay que entender el desafío de la democracia– es lo que Schmitt denomina Estado total.

    In this paper, we demonstrate that the modified equation of Emden type (MEE), x-doubledot + {alpha}xx-dot + {beta}x{sup 3} = 0, is integrable either explicitly or by quadrature for any value of {alpha} and {beta}. We also prove that the MEE possesses appropriate time-independent Hamiltonian functions for the full range of parameters {alpha} and {beta}. In addition we show that the MEE is intimately connected with two well-known nonlinear models, namely the equation of force-free Duffing-type oscillator and the two-dimensional Lotka-Volterra equation, and thus the complete integrability of the latter two models can also be understood in terms of the MEE.

En este intento, las muchedumbres nativas de Lima de principios del siglo XX desarrollaron una cotidiana lucha que tenía como escenario el mercado de trabajo que, a veces, llegaba a niveles altos de violencia como en las asonadas de mayo de 1909 en el que, como se apreciará en el artículo que sigue, los trabajadores chinos fueron blanco de las agresiones de una multitud que consideraba que los orientales desplazaban a nacionales y además contribuían a la depreciación del salario. THE MAY 1909 RIOTS. IMMIGRANTS AND NATIONALS IN THE LABOUR MARKET OF LIMA AT THE BEGINNING OF THE 20TH CENTURY. This article is part of a larger study that seeks to contribute to our understanding of a crucial period of peruvian history, 1890-1920. The study of urban riots allows us to analyze how a society that was going through the first stages of a modernization process, produced a form of lower-class protest characterized by the destruction of property, the lack of a permanent form of organization, certain manifestations of racial outrage, and above all, notions of legitimacy sanctioned by tradition. In addition, the study of urban riots allows us to understand how lower classes could influence economic and political developments, often for their own benefit. In this attempt, the native masses of early 20th century Lima carried on a daily struggle whose scenario was the labor market witch, on occasion, was characterized by high levels of violence, such as the May 1909 riots. As the article details, Chinese people were the target of the crowd’s fury, due to the belief that Chinese workers were displacing locals from their jobs and were a factor in the overall decline in salary rates.

    Fricke, V.

    1999-12-15

    The Size Reduction Machine (SRM) is a mobile platform capable of shearing various shapes and types of metal components at a variety of elevations. This shearing activity can be performed without direct physical movement and placement of the shear head by the operator. The base unit is manually moved and roughly aligned to each cut location. The base contains the electronics: hydraulic pumps, servos, and actuators needed to move the shear-positioning arm. The movable arm allows the shear head to have six axes of movement and to cut to within 4 inches of a wall surface.

    In most mammals, the Y chromosomal Sry gene initiates testis formation within the bipotential gonad, resulting in male development. SRY is a transcription factor and together with SF1 it directly up-regulates the expression of the pivotal sex-determining gene Sox9 via a 1.3-kb cis-regulatory element (TESCO) which contains an evolutionarily conserved region (ECR) of 180 bp. Remarkably, several rodent species appear to determine sex in the absence of Sry and a Y chromosome, including the mole voles Ellobius lutescens and Ellobius tancrei, whereas Ellobius fuscocapillus of the same genus retained Sry. The sex-determining mechanisms in the Sry-negative species remain elusive. We have cloned and sequenced 1.1 kb of E. lutescens TESCO which shares 75% sequence identity with mouse TESCO indicating that testicular Sox9 expression in E. lutescens might still be regulated via TESCO. We have also cloned and sequenced the ECRs of E. tancrei and E. fuscocapillus. While the three Ellobius ECRs are highly similar (94-97% sequence identity), they all display a 14-bp deletion (Δ14) removing a highly conserved SOX/TCF site. Introducing Δ14 into mouse TESCO increased both basal activity and SF1-mediated activation of TESCO in HEK293T cells. We propose a model whereby Δ14 may have triggered up-regulation of Sox9 in XX gonads leading to destabilization of the XY/XX sex-determining mechanism in Ellobius. E. lutescens/E. tancrei and E. fuscocapillus could have independently stabilized their sex determination mechanisms by Sry-independent and Sry-dependent approaches, respectively.

    Full Text Available As a result of the global political social and economic changes of the post-Soviet society at the turn of the 80th - 90th GG XX century, ossetian ethnos group was divided into two separate states. Problems and possible prospects of socio-economic integration of North Ossetia and South Ossetia, the consolidation of the Ossetian people and the preservation of its ethnic and cultural unity, most acutely heard in the 90s, have not lost their social significance today. The integration process at the present stage is one of cooperation between North Ossetia and South Ossetia in the various spheres of socio-political, socio-economic and cultural life. Cooperation in youth policy refers to the most promising areas of this process. Meanwhile, the existing problems in this area and possible prospects still remain out of view of researchers in both North and South Ossetia. The significance of the problems and the lack of it are determined by the relevance of research on this topic in general, and in particular the proposed article. Source base of this article are documents, coordinating youth policy at the national authorities and public national and patriotic associations, as well as materials of official and independent national press, chronologically related to the 90th years of XX century. Analyzing the documents and materials used method content analysis, as well as specific analytical approach to the published information, limiting the sample articles of interest topics. Research findings can be used for planning and organizing the youth policy at the national authorities and community youth organizations, as well as in the educational process.

    Few studies have focused on the quality of life (QoL) of patients with disorders of sex development (DSD). Our aim was to evaluate QoL in DSD patients with defined diagnoses followed until adulthood in a single tertiary centre. Adult patients with DSD (56 patients with 46,XX DSD - 49 with female social sex and 7 with male social sex as well as 88 patients with 46,XY DSD - 54 with female social sex and 34 with male social sex). QoL using WHOQOL-Bref questionnaire. Both patients with 46,XX DSD and patients with 46,XY DSD had similar QoL scores on the WHOQOL-Bref, comparable to the scores of the Brazilian general population. The chronological age at the start of treatment was negatively and significantly associated with general QoL score. Patients with male social sex DSD had better scores on the psychological domain than patients with female social sex DSD, as found in the Brazilian general population. In addition, among the 46,XY DSD group, the male social sex patients had better QoL compared with the female social sex patients. There was a positive and significant correlation between sexual performance and general QoL, although it explained only 4% of the variability of the general QoL score. The most influencing variables were general health, positive feelings and spirituality, religion and personal beliefs, each of them contributing with 18% of the variability of the general QoL score. Our large cohort of adult patients with DSD, which was followed by a multidisciplinary team in a single tertiary centre, had good QoL in adulthood; in addition, late treatment compromised the QoL of patients with DSD, whereas sexual performance has little influence on QoL. © 2014 John Wiley & Sons Ltd.

    A novel ionospheric tomography technique based on variable pixel size was developed for the tomographic reconstruction of the ionospheric electron density (IED) distribution. In variable pixel size computerized ionospheric tomography (VPSCIT) model, the IED distribution is parameterized by a decomposition of the lower and upper ionosphere with different pixel sizes. Thus, the lower and upper IED distribution may be very differently determined by the available data. The variable pixel size ionospheric tomography and constant pixel size tomography are similar in most other aspects. There are some differences between two kinds of models with constant and variable pixel size respectively, one is that the segments of GPS signal pay should be assigned to the different kinds of pixel in inversion; the other is smoothness constraint factor need to make the appropriate modified where the pixel change in size. For a real dataset, the variable pixel size method distinguishes different electron density distribution zones better than the constant pixel size method. Furthermore, it can be non-chided that when the effort is spent to identify the regions in a model with best data coverage. The variable pixel size method can not only greatly improve the efficiency of inversion, but also produce IED images with high fidelity which are the same as a used uniform pixel size method. In addition, variable pixel size tomography can reduce the underdetermined problem in an ill-posed inverse problem when the data coverage is irregular or less by adjusting quantitative proportion of pixels with different sizes. In comparison with constant pixel size tomography models, the variable pixel size ionospheric tomography technique achieved relatively good results in a numerical simulation. A careful validation of the reliability and superiority of variable pixel size ionospheric tomography was performed. Finally, according to the results of the statistical analysis and quantitative comparison, the

    Hailstorm damage to the Space Shuttle's External Tank inspired a NASA innovation with extensive photography applications. In order to measure the defects caused by the storm, Kennedy Space Center used telephoto lenses to zoom in on the tank and view the damage clearly. However, since there was no reference object in the image, the engineers could not determine the scale of the damage. In photographic situations similar to this, an object, such as a ruler, is placed within the field of view. This allows a person to look at a photograph and have a visual indication of the scale of the objects in it. In the External Tank situation, however, this procedure was not possible. As a solution, Kennedy developed the Scaling and Measurement Device for Photographic Images, which provides a non-intrusive means of adding a scale to a photograph. In addition to meeting Kennedy's needs, scaling images is extremely important in crime and accident scene investigations, oil and chemical tank monitoring, and aerial photography. The innovation consists of a tool that attaches directly to a camera or charge coupled device using a standard screw. Two lasers fitted to the device provide parallel beams that are set 1 inch apart. These lasers enable the device to project a pattern into the field of view. When a photograph is taken, the image of the laser pattern appears, along with the image of the object under investigation, allowing the viewer quantifiable information as to the size of the object. The laser beams are accurate to approximately 200 feet. Windows-based software was developed to work with the scaling device tool. The software provides further techniques to measure objects in photographs and digital images. By using the software, any object in the image can be measured diagonally, vertically, and horizontally. The device and its software enable the user to determine two-dimensional measurements within a photograph.

  8. Sizing of scramjet vehicles

    The current European project LAPCAT II has the ambitious goal to define a conceptual vehicle capable of achieving the antipodal range Brussels-Sydney (~18,000 km) in about 2 h at Mach number Ma = 8. At this high speed, the requirement of high lift to drag (L/D) ratio is critical to high performance, because of high skin friction and wave drag: in fact, as the Mach number increases, the L/D ratio decreases. The design of the vehicle architecture (shape and propulsion system) is, as a consequence, crucial to achieve a reasonably high L/D. In this work, critical parameters for the preliminary sizing of a hypersonic airbreathing airliner have been identified. In particular, for a given Technology Readiness Level (TRL) and mission requirements, a solution space of possible vehicle architectures at cruise have been obtained. In this work, the Gross Weight at Take-Off (TOGW) was deliberately discarded as a constraint, based on previous studies by Czysz and Vanderkerkhove [1]. Typically, limiting from the beginning, the TOGW leads to a vicious spiral where weight and propulsion system requirements keep growing, eventually denying convergence. In designing passenger airliners, in fact, it is the payload that is assumed fixed from the start, not the total weight. In order to screen the solutions found, requirements for taking-off (TO) and landing as well as the trajectory have been accounted for. A consistent solution has finally been obtained by imposing typical airliner constraints: emergency take-off and landing. These constraints enable singling out a realistic design from the broad family of vehicles capable of performing the given mission. This vehicle has been obtained by integrating not only aerodynamics, trajectory, and airliner constraints, but also by integrating the propulsion system, the trimming devices and by doing some adjustments to the conceptual vehicle shape (i. e., spatular nose). Thus, the final vehicle is the result of many iterations in the design

    The purpose of the study was to create detector element-specific angular correction factors for each detector of the MatriXX planar ion chamber array and compare them to vendor-default angular correction factors. Additionally, the impact of both factors on gamma index was quantified using two corrections. The correction factor of each element is determined irradiating the detector at different incidences by the ratio of the calculated expected dose to the MatriXX measured dose as a gantry angle function. To evaluate its impact, sixty-five pre-irradiated patient-specific dose validations were re-analyzed using the gamma index with: 3%/3 mm, 2%/2 mm, 1%/1 mm criteria. The factors for 6 MV were found to differ (7%) from the default ones for specific angles particularly for 85 degree centigrade to 95 degree centigrade. For 10 MV, differences (1.0%) existed when correction factors were created using various ROI's. Two corrections were proposed, absolute differences for 3%/3 mm, 2%/2 mm, and 1%/1 mm were up to 1.5%, 4.2% and 4.1% ( p < 0.01), respectively. Large differences in the default and specific factors were noted for 6 MV and lead to improvement of the absolute gamma index value of up to 4.2%. In general, gamma index value increases for patient specific dose validations when using device specific factors. (Author)

    The human penis exhibits considerable variation in size, while a substantial proportion of the adult male population experiences size anxiety. This paper employs an evolutionary framework in order to understand this variation, as well as the concern men exhibit about the adequacy of the size of their penis. It is argued that female choice has been one important sexual selection force, responsible for shaping the size of the penis. However, this force has been relatively weak, because women do...

  11. Sauropod dinosaurs evolved moderately sized genomes unrelated to body size.

    Sauropodomorph dinosaurs include the largest land animals to have ever lived, some reaching up to 10 times the mass of an African elephant. Despite their status defining the upper range for body size in land animals, it remains unknown whether sauropodomorphs evolved larger-sized genomes than non-avian theropods, their sister taxon, or whether a relationship exists between genome size and body size in dinosaurs, two questions critical for understanding broad patterns of genome evolution in dinosaurs. Here we report inferences of genome size for 10 sauropodomorph taxa. The estimates are derived from a Bayesian phylogenetic generalized least squares approach that generates posterior distributions of regression models relating genome size to osteocyte lacunae volume in extant tetrapods. We estimate that the average genome size of sauropodomorphs was 2.02 pg (range of species means: 1.77-2.21 pg), a value in the upper range of extant birds (mean = 1.42 pg, range: 0.97-2.16 pg) and near the average for extant non-avian reptiles (mean = 2.24 pg, range: 1.05-5.44 pg). The results suggest that the variation in size and architecture of genomes in extinct dinosaurs was lower than the variation found in mammals. A substantial difference in genome size separates the two major clades within dinosaurs, Ornithischia (large genomes) and Saurischia (moderate to small genomes). We find no relationship between body size and estimated genome size in extinct dinosaurs, which suggests that neutral forces did not dominate the evolution of genome size in this group.

Las transiciones o cambios sufridos se pueden visualizar en el siglo XX con el régimen de Porfirio Díaz, que duró más de treinta años, en donde el país se vio impactado por la industrialización y la introducción de arte y arquitectura de tipo ecléctica, al periodo de la revolución en donde se quería despojar un régimen autoritario y buscar una identidad, hecho que encaminó la proclamación de la Constitución (1917, posteriormente en 1929 la permanencia de un partido político, que permaneció setenta años en la presidencia, el cual se desgastó en conmemorar a personajes de la política en parques y jardines, hasta la denominada alternancia signo de una aparente democracia. Todos estos periodos han caracterizado a México y sus espacios abiertos, incluidas las actividades sociales. El presente trabajo aborda el estudio del espacio público que se desarrolló durante el siglo XX impactado por las dictaduras tanto oficiales como las no oficiales definidas en tres momentos, en un primer ciclo con el gobierno porfirista, seguido de la etapa postrevolucionaria o constitucionalista y el último caracterizado por una visión unipartidista con la entrada de el PNR1 posteriormente PRI2.

    Body size, and, by extension, growth has impacts on physiology, survival, attainment of sexual maturity, fecundity, generation time, and population dynamics, especially in ectotherm animals that often exhibit extensive growth following attainment of sexual maturity. Frequently, growth is analyzed at the population level, providing useful population mean growth parameters but ignoring individual variation that is also of ecological and evolutionary significance. Our long-term study of Lake Erie Watersnakes, Nerodia sipedon insularum, provides data sufficient for a detailed analysis of population and individual growth. We describe population mean growth separately for males and females based on size of known age individuals (847 captures of 769 males, 748 captures of 684 females) and annual growth increments of individuals of unknown age (1,152 males, 730 females). We characterize individual variation in asymptotic size based on repeated measurements of 69 males and 71 females that were each captured in five to nine different years. The most striking result of our analyses is that asymptotic size varies dramatically among individuals, ranging from 631-820 mm snout-vent length in males and from 835-1125 mm in females. Because female fecundity increases with increasing body size, we explore the impact of individual variation in asymptotic size on lifetime reproductive success using a range of realistic estimates of annual survival. When all females commence reproduction at the same age, lifetime reproductive success is greatest for females with greater asymptotic size regardless of annual survival. But when reproduction is delayed in females with greater asymptotic size, lifetime reproductive success is greatest for females with lower asymptotic size when annual survival is low. Possible causes of individual variation in asymptotic size, including individual- and cohort-specific variation in size at birth and early growth, warrant further investigation.

  17. On the Relationship between Pollen Size and Genome Size

    Directory of Open Access Journals (Sweden)

    Charles A. Knight

    2010-01-01

    Full Text Available Here we test whether genome size is a predictor of pollen size. If it were, inferences of ancient genome size would be possible using the abundant paleo-palynolgical record. We performed regression analyses across 464 species of pollen width and genome size. We found a significant positive trend. However, regression analysis using phylogentically independent contrasts did not support the correlated evolution of these traits. Instead, a large split between angiosperms and gymnosperms for both pollen width and genome size was revealed. Sister taxa were not more likely to show a positive contrast when compared to deeper nodes. However, significantly more congeneric species had a positive trend than expected by chance. These results may reflect the strong selection pressure for pollen to be small. Also, because pollen grains are not metabolically active when measured, their biology is different than other cells which have been shown to be strongly related to genome size, such as guard cells. Our findings contrast with previously published research. It was our hope that pollen size could be used as a proxy for inferring the genome size of ancient species. However, our results suggest pollen is not a good candidate for such endeavors.

Este ensayo observa las transformaciones que esta actividad ha tenido en las diferentes épocas de desarrollo de la ciudad de México, a través del análisis de los productores de la imagen y del imaginario alrededor de este tipo de comercio, transmitido por medio de la pintura de castas o de la fotografía. Los tres artículos que conforman este ensayo, intentan indagar de forma general cómo se ha representado el ambulantaje en cada época, qué rasgos de esta actividad se modifican y cuáles se mantiene en el paso de un período a otro, de qué forma el análisis de las representaciones de una temporalidad nos ayuda a entender las imágenes propagadas en los siguientes periodos. Los autores abordaron principalmente tres dimensiones de la representación del ambulantaje para cada periodo: la social, la territorial y la económica. A pesar de las diferentes fuentes y perspectivas de análisis, logramos identificar aspectos que permanecen constantes en este largo periodo y que nos permiten entender la dinámica del fenómeno social de este tipo de comercio en la ciudad de México, dentro de un marco histórico y tradicional. Por otro lado, es concluyente que el ambulantaje es una actividad que se adapta a las cambiantes condiciones del espacio público, y que esta adaptabilidad hace posible su realización en los diferentes momentos del desarrollo urbano de la ciudad.

    Full Text Available This article studies the ideas of a number of 19th and 20th Century political thinkers in regard to national projects which were inclusive or exclusive of subordinate groups such as Indians and Ladinos. The 19th Century inclusive position of José Cecilio del Valle and the more exclusive one conceived by Batres Jauregui are analyzed, as well as the reasons why these types of ideas are still prevailing. In the 20th Century, the analysis includes exclusion defenders such as Horacio Altamirano and their opposites, like Juárez Muñoz. The whole article is pervaded with the ideas of the so called Generación del 20, the analysis of which is particularly original and important to understand arguments which have prevailed till the present day and are used to support theories for the inclusion and/or exclusion of Indians in the nation project of Guatemala.

    En este artículo se exponen con cierto rigor las tesis de algunos de los pensadores políticos del siglo XIX y XX, en torno a los proyectos de nación incluyentes o excluyentes de los grupos subalternos, indios o ladinos. Se analizan a lo largo del siglo XIX las posiciones más incluyentes, representadas por José Cecilio del Valle, o las excluyentes, Batres Jáuregui y se analiza el proceso por el cual estas tesis siguen perdurando hasta el momento actual. Se pueden encontrar defensores de la exclusión en Horacio Altamirano o de la inclusión, Juárez Muñoz, durante el primer cuarto del siglo XX. El análisis de algunos pensadores de la llamada Generación del 20 permea todo este artículo y representa un novedoso análisis y una veta de trabajo realmente importante para comprender cuáles han sido algunos de aquellos argumentos que se siguen utilizando incluso en el presente, para seguir sosteniendo las teorías de la exclusión o inclusión de los indígenas en el proyecto de nación guatemalteco.

In this period, literary works were often inspired by the art of painting. The focus is on the poetry of Zofia Gordziałkowska, which was largely motivated by her fascination with the then popular Swedish painter Arnold Böcklin, whose works are populated mainly by characters from the Bible and classical mythology. The reconstruction of the concept of the soul based on the texts is juxtaposed with general language data.

The conclusions of the interdisciplinary examination are connected with symbolism as both an artistic movement within modernism and a philosophy of the turn of the 20th century.   Językowy obraz duszy w ekfrazach z przełomu XIX i XX wieku na podstawie wybranych wierszy Zofii Gordziałkowskiej Celem rozważań jest ukazanie językowego obrazu duszy zawartego w młodopolskich ekfrazach Zofii Gordziałkowskiej, zafascynowanej popularnym wówczas w Europie malarstwem Szwajcara Arnolda Böcklina. Jego dzieła zaludniają głównie postaci z mitologii antycznej i Biblii. Zrekonstruowanie pojęcia duszy na podstawie tekstów artystycznych i przedstawienie na tle danych zawartych w języku ogólnym doprowadziło do ustalenia różnicy między jego rozumieniem w tych odmianach języka. Analiza materiału z wykorzystaniem głównie metodologii kognitywizmu, dążącej do zbadania konceptualizacji pojęcia, jego profilowania i kategoryzacji, pozwoliła na nietradycyjne odczytanie poezji i wzbogacenie istniejących badań z zakresu lingwistyki kognitywnej

    Full Text Available Este artigo analisa a especialização da produção agrícola nas regiões e nas propriedades rurais do estado de São Paulo no início do século XX, após décadas de transformações causadas pela difusão da lavoura do café. O trabalho utiliza dados de mais de 40 mil propriedades rurais para examinar a estrutura de produção e a especialização produtiva em onze regiões que cobrem a totalidade do território do estado de São Paulo no auge da economia cafeeira. Além das regiões, o artigo aborda como as propriedades rurais distribuíram seus recursos produtivos entre produto de exportação (café e produtos destinados ao consumo interno. A análise traz à luz novas evidências, corroborando parte da literatura, mas divergindo de outras ideias estabelecidas na historiografia. No início do século XX, virtualmente todas as regiões de São Paulo produziam café, mas quase todas elas se especializaram em mais de um produto agrícola, com a exceção da região da Mogiana. Além das grandes propriedades ressaltadas na literatura, as pequenas propriedades também foram atraídas para a produção de exportação e se especializaram na produção do café. Por sua vez, as grandes propriedades não só se especializaram na produção de alimentos (além do café, mas dominaram a oferta dos principais produtos destinados ao mercado doméstico.

I depart here from the hypothesis that, to the middle of the XX century, the profound social differences that characterized the argentinian society were reproduced and naturalized in the Church, per both, ecclesiasticals and laics. This acquires particular implications for the operation of the one association self-styled laborer as the JOC, if it goes attached to an identification of the manual worker as a suspected being and with limited compression capacities. Anyway, this visions of intellectual and social inferiority, accepted uncritically by the jocists, coexisted with self representations of moral superiority respect to the elites questioned by their selfishness and hypocrisy, what contributed to deepen the contrasts of classes and the social distances inside the Church.La propuesta de este trabajo es el análisis de las diversas representaciones de clase y dinámicas de relación entre la Juventud Obrera Católica (JOC argentina y la jerarquía eclesiástica; en relación con miembros de otras organizaciones laicales y en el interior de la asociación, entre asesores eclesiásticos y jocistas.

    Full Text Available The influence of the SiCp proportion on the pitting corrosion of A3xx.x/SiC/xxp composites was studied by means of potenciodinamic polarization and double cyclic polarization in saline environment at 25 °C. A360/SiC/xxp matrix does not contain copper, whereas the A380/SiC/xxp matrix contains l,39'l,44w %Ni and 3,13-3,45wt %Cu. The kinetic study was carried out by gravimetric measurements. The nature of corrosion products was analysed by low angle XRD and Scanning Electron Microscopy (SEM. The corrosion is due to nucleation and growth of Al2O3·3H2O on the material surface. The corrosion increases with the reinforcement proportion, chloride concentration and copper content.

    Full Text Available The synaptonemal complex (SC surface-spreading technique was used to visualize the process of chromosome synapsis in spermatocytes and oocytes of E. talpinus Pallas, 1770, a species with the XX sex chromosome system in both males and females. We used electron microscopy and immunofluorescent localization of synaptonemal complex protein (SCP3 and centromeric proteins to analyze the structure and behaviour of synaptonemal complexes in prophase I of meiosis, aiming to reveal signs of meiotic sexual dimorphism in this species. We present evidence of considerable differences in the structure and behaviour of the axial structures of sex bivalents in male and female meiosis, despite the isomorphic G- and C-banding patterns of mitotic sex chromosomes. During meiotic prophase I, the sex bivalent in females behaved as autosomal bivalents, but it was not involved in the formation of the bouquet configuration or it was the first to leave it. The XX chromosomes of males formed closed sex bivalents. Only short tracts of SC were formed at both ends of the sex bivalent, while large middle segments of the lateral elements remained unpaired. The male sex chromosomes also formed characteristic “sex bodies”. In fact, electron microscopy revealed dense nucleolus-like bodies associated with unpaired parts of the axial elements. These regions of the sex chromosomes were poorly immunostained, because the distribution of SCP3 had a peculiar powder-like pattern, but SCP3 was not associated with the nucleolus-like bodies. We also revealed signs of sexual dimorphism in the dynamics of formation and destruction of autosomal SCs. In males, the total SC length was shorter than in females. The chromosome bouquet configuration was preserved up to the stage of early pachytene in females. The bouquet configuration in males was not expressed. At late pachytene, gaps were revealed in the structure of autosomal SCs in spermatocytes immunostained with antibodies to SCP3. The

  5. Size did not matter: An evolutionary account of the variation in penis size and size anxiety

    Directory of Open Access Journals (Sweden)

    2016-12-01

    Full Text Available The human penis exhibits considerable variation in size, while a substantial proportion of the adult male population experiences size anxiety. This paper employs an evolutionary framework in order to understand this variation, as well as the concern men exhibit about the adequacy of the size of their penis. It is argued that female choice has been one important sexual selection force, responsible for shaping the size of the penis. However, this force has been relatively weak, because women do not consider the size of their partners’ penis to be the most important determinant of their sexual satisfaction. Also, in ancestral human societies, sexual satisfaction was a secondary concern, while women had limited space to exercise mate choice. The mismatch between ancestral and modern conditions, with female choice being stronger in the present than in the past, causes anxiety in men about their ability to satisfy their partners, which is also manifested in their concerns about size.

    Full Text Available Abstract Background To evaluate the effect of food aroma on bite size, a semisolid vanilla custard dessert was delivered repeatedly into the mouth of test subjects using a pump while various concentrations of cream aroma were presented retronasally to the nose. Termination of the pump, which determined bite size, was controlled by the subject via a push button. Over 30 trials with 10 subjects, the custard was presented randomly either without an aroma, or with aromas presented below or near the detection threshold. Results Results for ten subjects (four females and six males, aged between 26 and 50 years, indicated that aroma intensity affected the size of the corresponding bite as well as that of subsequent bites. Higher aroma intensities resulted in significantly smaller sizes. Conclusions These results suggest that bite size control during eating is a highly dynamic process affected by the sensations experienced during the current and previous bites.

  15. Cell Size Regulation in Bacteria

    Science.gov (United States)

    Amir, Ariel

    2014-05-01

    Various bacteria such as the canonical gram negative Escherichia coli or the well-studied gram positive Bacillus subtilis divide symmetrically after they approximately double their volume. Their size at division is not constant, but is typically distributed over a narrow range. Here, we propose an analytically tractable model for cell size control, and calculate the cell size and interdivision time distributions, as well as the correlations between these variables. We suggest ways of extracting the model parameters from experimental data, and show that existing data for E. coli supports partial size control, and a particular explanation: a cell attempts to add a constant volume from the time of initiation of DNA replication to the next initiation event. This hypothesis accounts for the experimentally observed correlations between mother and daughter cells as well as the exponential dependence of size on growth rate.

    Full Text Available En la historia del urbanismo, la segunda mitad del siglo XX marca un punto de inflexión. Los métodos de desarrollo urbano aplicados hasta la fecha ya no consiguen dar respuesta a los problemas surgidos en el corazón de las ciudades: guetos, inseguridad o delincuencia. Resulta necesario buscar nuevos métodos para la recuperación del pulso vital de nuestros barrios. Kreuzberg en Berlín, el centro histórico de Bolonia, Le Marais en París, Fener y Balat en Estambul, Molenbeek en Bruselas, Mouraria en Lisboa y Lavapiés en Madrid se han convertido en ejemplos paradigmáticos de la nueva idea de rehabilitación urbana. La diversidad social, que evita la creación de guetos; la calidad de los espacios públicos, que favorece las relaciones interpersonales; y la salvaguarda, que mantiene y fortalece la imagen que tenemos de nuestro entorno urbano, se convierten en conceptos necesarios para recuperar nuestra "ciudad herida".

    We have synthesized a series of intermetallic ternary phosphide chalcogenide superconductors, AP2-xXx (A = Zr, Hf; X = S, Se), using the high-pressure synthesis technique. These materials have a PbFCl-type crystal structure (space group P4/nmm) when x is greater than 0.3. The superconducting transition temperature Tc changes systematically with x, yielding dome-like phase diagrams. The maximum Tc is achieved at approximately x = 0.7, at which point the Tc is 6.3 K for ZrP2-xSex (x = 0.75), 5.5 K for HfP2-xSex (x = 0.7), 5.0 K for ZrP2-xSx (x = 0.675), and 4.6 K for Hfp2-xSx (x = 0.5). They are typical type-II superconductors and the upper and lower critical fields are estimated to be 2.92 T at 0 K and 0.021 T at 2 K for ZrP2-xSex (x = 0.75), respectively.

Authors state results of the analysis of the historical sources allowing to track process of emergence and development of elementary church schools in the region undertaken by it. Aspects of institute’s work are covered of diocesan observers and diocesan school boards. The existing church schools were the only possibility of familiarizing with knowledge of the basic to the population of the region of this period. The value of educational activity of church was especially great, at extensiveness of territories, big remoteness of settlements from each other and lack of territorial establishments in Western Siberia. The conclusion is that the system of church schools was developed in parallel with system of secular education of similar level. The competition between two systems forced to find new effective methods of work and constantly to improve vocational training of teaching personnel that eventually played a positive role in development of domestic primary education.

    José Javier Plumed Domingo

    Full Text Available Resumen En el trabajo se estudian los discursos sobre la cura que elaboraron los médicos mentalistas españoles en la transición del siglo XIX al XX. Si en las décadas de los años 1870 y 1880 el discurso preponderante promulgado por los médicos pertenecientes a instituciones privadas era extremadamente optimista, posteriormente cambió y se orientó hacia un mayor pesimismo terapéutico. Sin embargo, dadas las necesidades profesionales de los frenópatas, siguieron mostrando una confianza más o menos firme hacia las capacidades terapéuticas de la psiquiatría. La recepción de las nuevas nosologías, como la de Kraepelin, estuvo condicionada, en parte, por la actitud hacia la cura de los médicos mentalistas de la época y fue aceptada de forma ambivalente.

    Among farm animals, pigs are known to show XX sex-reversal. In such cases the individuals are genetically female but exhibit a hermaphroditism, or a male phenotype. While the frequency of this congenital disease is quite low (less than 1%), the economic losses are significant for pig breeders. These losses result from sterility, urogenital infections and the carcasses being downgraded because of the risk of boar taint. It has been clearly demonstrated that the SRY gene is not involved in most cases of sex-reversal in pigs, and that autosomal recessive mutations remain to be discovered. A whole-genome scan analysis was performed in the French Large-White population to identify candidate genes: 38 families comprising the two non-affected parents and 1 to 11 sex-reversed full-sib piglets were genotyped with the PorcineSNP60 BeadChip. A Transmission Disequilibrium Test revealed a highly significant candidate region on SSC12 (most significant p-valueTesco. However, no causal mutations could be identified in either of the two sequenced regions. Further haplotype analyses did not identify a shared homozygous segment between the affected pigs, suggesting either a lack of power due to the SNP properties of the chip, or a second causative locus. Together with information from humans and mice, this study in pigs adds to the field of knowledge, which will lead to characterization of novel molecular mechanisms regulating sexual differentiation and dysregulation in cases of sex reversal.

On the basis of archival materials considered the chronology of the process, motives, forms and specifics of business involvement in regional political organizations, conducted a comparison of the phenomena studied in the Yenisei province to other regions of the Russian Empire, identified factors that determined the transformation of the political views of the merchants over the post-reform period. On the basis of the participation of the guild merchants in the political life of the Yenisei province, the authors came to the conclusion that at the beginning of the test period, the political culture of the Yenisei merchants had mostly traditional, passively subservient character. Since the end of the XIX century. as a result of the emerging civil revitalization of the merchant community, its political culture began to take on characteristics of modernization, such as: awareness of class and regional interests expressed through claims of representation in the government.

    Full Text Available El objetivo del artículo es analizar los debates que en los primeros años del siglo XX se desarrollaron en el interior del Partido Socialista argentino en torno al modo de intervención en el movimiento anticlerical. En particular, examina la polémica que se trabó entre Alfredo Palacios y la dirección partidaria, a propósito de la creación de los llamados “círculos de obreros liberales”. El artículo reconstruye estos debates, hasta ahora inexplorados por la historiografía, a través de un examen de la prensa socialista y anticlerical del período. La investigación argumenta que, si bien el Partido Socialista otorgó un lugar destacado a las denuncias contra el clero y fue parte activa del movimiento anticlerical, desarrolló al mismo tiempo una delimitación con otros sectores del mismo.

    Balanced autosomal translocations are a known cause for repeated early embryonic loss (REEL) in horses. In most cases, carriers of such translocations are phenotypically normal, but the chromosomal aberration negatively affects gametogenesis giving rise to both genetically balanced and unbalanced gametes. The latter, if involved in fertilization, result in REEL, whereas gametes with the balanced form of translocation will pass the defect into next generation. Therefore, in order to reduce the incidence of REEL, identification of translocation carriers is critical. Here, we report about a phenotypically normal 3-year-old Arabian mare that had repeated resorption of conceptuses prior to day 45 of gestation and was diagnosed with REEL. Conventional and molecular cytogenetic analyses revealed that the mare had normal chromosome number 64,XX but carried a non-mosaic and non-reciprocal autosomal translocation t(4;10)(q21;p15). This is a novel translocation described in horses with REEL and the first such report in Arabians. Previous cases of REEL due to autosomal translocations have exclusively involved Thoroughbreds. The findings underscore the importance of routine cytogenetic screening of breeding animals. © 2015 Blackwell Verlag GmbH.

Se muestra como la Iglesia constituye un proyecto fundamental de modernización religiosa, que se denota ante todo en la extensión de su presencia en el territorio vallecaucano. Proceso que inicia con la desfragmentación del gran territorio de la arquidiócesis de Popayán, con lo cual cada diócesis creada logra impulsar sus propios procesos de generación de parroquias, centros educativos y de beneficencia, logrando con esto, construir la iglesia vallecaucana y fortalecer la religión católica tanto en los sectores rurales como en los espacios urbanos del departamento del Valle del Cauca. Cada nueva diócesis se inscribe además, en su propia coyuntura local de desarrollo y modernización económica y social.

    To examine factors associated with emotional well-being in women with spontaneous primary ovarian insufficiency. Cross-sectional and case-control study. Clinical research center, national U.S. health research facility. Women diagnosed with spontaneous 46,XX primary ovarian insufficiency (n = 100) at a mean age of 32.4 years and healthy control women of similar age (n = 60). Administration of validated self-reporting instruments. Illness uncertainty, stigma, goal disengagement/re-engagement, purpose in life, Positive and Negative Affect Schedule, Center of Epidemiologic Studies Depression Scale, State-Trait Anxiety Inventory. Compared with controls, women with spontaneous primary ovarian insufficiency scored adversely on all measures of affect. Illness uncertainty and purpose in life were significant independent factors associated with anxiety (R(2) = 0.47), stigma and purpose in life were the significant independent factors associated with depression (R(2) = 0.51), and goal re-engagement and purpose in life were significantly and independently associated with positive affect (R(2) = 0.43). This evidence supports the need for prospective studies. Our findings are consistent with the hypothesis that clinicians could improve the emotional well-being of their patients with primary ovarian insufficiency by [1] informing them better about their condition, [2] helping them to feel less stigmatized by the disorder, and [3] assisting them in developing alternative goals with regard to family planning as well as other goals.

    The genus Colomesus is the sole representative of the family Tetraodontidae in the Amazon region. Here, Colomesus asellus was analyzed using conventional and molecular cytogenetic protocols. Its diploid chromosome number is 2n = 46 with 12 meta-, 10 submeta-, 16 subtelo-, and 8 acrocentric chromosomes and a fundamental number of FN = 84. An XX/XY sex chromosome system was identified. Mapping of 18S rDNA correlated with the nucleolus organizer regions (Ag-NORs) in the short arms of the 2 X chromosomes in females and in the Y chromosome in males. C-banding revealed heterochromatin in the centromeric regions of all chromosomes, except for pair 3. Prominent sex chromosome-specific heterochromatin amplification was observed, covering the short arms of the Y chromosome almost entirely. FISH with telomeric and tropomyosin (tpm1) sequences, respectively, revealed terminal signals in all chromosomes. The analysis of extended DNA fibers confirmed the colocalization and the interspersed pattern of the telomeric and tpm1 sequences. Thus, this study highlights the remarkable evolutionary dynamism presented by the Amazonian puffer fish regarding the differentiation of a heteromorphic XY sex chromosome system and a particular sex-specific amplification of rDNA sites. This is the first record of such an association in the Tetraodontidae family. © 2017 S. Karger AG, Basel.

Las argumentaciones para que esto se diera pasaron por teorías raciales, médicas y sociales que estaban en boga en este momento. En este sentido, los médicos colombianos−gracias a la ideología racialista con la cual estaban armados− construyeron un discurso pro higienismo con el cual intentaron la institucionalización de un aparato higienista que fuera apropiado para la nación. El estudio se hace a partir de las siguientes fuentes: legislación, informes presentados al Congreso de la República, memorias de congresos médicos, entre otros, y fueron analizadas desde la perspectiva de análisis del discurso.

The author has tried to demonstrate a variety of everyday and festive street entertainment of citizens and their changes. Military parades, mass celebrations, charity and sport’s events played an important role in the local community unit, filling the leisure time of citizens by the wholesome entertainment. The voluntary associations played an important role in the organization of outdoor activities of the citizens. Sporting events, camping trips contributed to the physical development of children and adults. The voluntary associations had paid a lot of attention to the organization of entertainment spaces: the construction of a variety of sports facilities in urban gardens and in the dachas area, decorating gardens during charity events. Most practices of street entertainment in the cities of the Russian Far East were not local invention. It was introduced from the European part of Russian Empire and Western Europe and China. Chinese migrants brought the New Year celebrations on the eastern calendar, the Chinese street performers, acrobats and jugglers on the Russian Far East. The new forms of social activity in the sphere of leisure became an expression of the transformation of the traditional culture and the development of urban lifestyle.

    Full Text Available En México heterodoxo, reunión del trabajo de investigación realizado a lo largo de una década, José Ricardo Chaves rastrea las manifestaciones de “religiosidad heterodoxa” en la literatura hispánica de finales del siglo xix y de principios del xx, a partir de la premisa de que la secularización de las instituciones y del espacio social permitió el auge de expresiones religiosas ajenas al catolicismo. Entre ellas el autor destaca el ocultismo, en sus vertientes de espiritismo y teosofía, y el orientalismo; de ahí que en la introducción se delimiten conceptos como ‘ocultismo’, ‘teosofía’, ‘espiritismo’ y se exponen las características que diferencian a las ciencias ocultas de otras “religiosidades heterodoxas”. En este sentido, cabe señalar que para el autor la heterodoxia no sólo comprende el racionalismo o el protestantismo decimonónicos, sino que es una categoría que se hace extensiva a las ciencias ocultas y a las religiones orientales frente a un catolicismo que empezaba a debilitarse en el ámbito hispánico.

    Full Text Available Based on different scholars’ works of the 19th and 20th centuries as well as on oral testimonies collected in Cuba, I intend to show in this paper that besides the purely economic reasons, there were also other psychosocial and frequently decisive factors involved in the final decision of a significant number of Galicians who emigrated to Cuba, without which they would probably have never decided to leave their homes. This fact might also be applied to other migratory processes of other Spanish regions during the period of Spaniards’ mass emigration to America.

    En este artículo intento destacar, basándome en diferentes tratadistas de los siglos XIX y XX y en testimonios orales recogidos en Cuba, cómo además de las causas económicas actuaron también, y con frecuencia decisivamente, otros factores de tipo psicosocial en la decisión migratoria de muchos de los gallegos que emigraron a Cuba, sin los cuales, probablemente, nunca se hubiesen decidido a abandonar sus hogares. Hecho que bien se podría hacer extensivo a los demás procesos migratorios de otras regiones de España durante el período de emigración masiva de españoles hacia América.

La experiencia de estas reuniones alternativas reflejaron el mal estado en que se encontraba el profesorado de enseñanza primaria en España, por lo que su realización fue necesaria para plantear temas eminentemente pedagógicos y de práctica educativa a fin de reflexionar y tomar decisiones respecto al futuro de la enseñanza y de los profesionales del magisterio. Estas Conferencias fueron de gran interés y se llevaron a cabo hasta el primer tercio del siglo XX. Los problemas internos de organización, las malas condiciones del magisterio y la escasa relevancia social durante los últimos años posibilitaron su caída y consecuente desaparición.

    Among farm animals, pigs are known to show XX sex-reversal. In such cases the individuals are genetically female but exhibit a hermaphroditism, or a male phenotype. While the frequency of this congenital disease is quite low (less than 1%), the economic losses are significant for pig breeders. These losses result from sterility, urogenital infections and the carcasses being downgraded because of the risk of boar taint. It has been clearly demonstrated that the SRY gene is not involved in most cases of sex-reversal in pigs, and that autosomal recessive mutations remain to be discovered. A whole-genome scan analysis was performed in the French Large-White population to identify candidate genes: 38 families comprising the two non-affected parents and 1 to 11 sex-reversed full-sib piglets were genotyped with the PorcineSNP60 BeadChip. A Transmission Disequilibrium Test revealed a highly significant candidate region on SSC12 (most significant p-valuesex reversal.

Essas transformações produziram mudanças rápidas e radicais na produção, nos processos de trabalho, hábitos de consumo, poderes e prática do Estado, com desdobramentos para todas as instâncias da sociedade em todo o planeta. A reestruturação da produção ampliou significativamente a divisão do trabalho, com as novas tecnologias e novas formas de gestão, com consequências de grandes reduções no número de postos de trabalho, elevando o número de trabalhadores desempregados, assim como vem ocorrendo um processo de precarização do trabalho. Desta forma, o capital tem ampliado a exploração do trabalhador, exigindo que seja polivalente, flexível, possuidor de múltiplas competências, apto para cumprir múltiplas funções.

There are no observations concerning women-musicians in the XIX century or in the centuries before, neither in Polish ethnography nor in the ethomusicological literature. Women probably played musical instruments, but only at home or while tending domestic animals, however there is a lack of any source confirmation of public performances of women musicians. On account of the rare literature on the topic of gender studies in the field of Polish traditional music and the lack of the gender-thread in the remaining ethnomusicological literature, information on the topic of the current position of women-musicians was gathered first of all during interviews with them and with their families. The analysis is related to the way they speak about their own activities, performances, experiences. The author refers to opinions of only some selected interviewees, the most characteristic of particular generations. The first generation is represented by women born near the end of the XIX century, the second by women born before World War II, the third by women born directly after World War II. Women born after the 50’s and 60’s of the XX century are part of the fourth generation, because at that time the differences in the gender situation had become less apparent.   Sytuacja kobiet muzykantek w Polsce – studium przykładów od początku XX wieku do dziś Celem niniejszego artykułu jest scharakteryzowanie przebiegu zmian zachodzących w tradycyjnej kulturze muzycznej, na postawie życiorysów wybranych muzykantek, począwszy od ścisłego przestrzegania ról i funkcji obydwu p

    Full Text Available En las últimas décadas se ha producido una profunda renovación y expansión de los estudios sobre elites y grupos dirigentes en la Argentina. Num erosas investigaciones que han utilizado herramientas novedosas provenientes de distintos espacios disciplinares de las ciencias sociales, tales como la antropología y la sociología, han salido a la luz en el último período, ilustrando una mayor complejidad en la comprensión de los fenómenos económicos, políticos y sociales. Esta expansión tanto cuantitativa como cualitativa de las investigaciones históricas, sociológicas y antropológicas no puede ser escindida del conjunto de factores que permitió la consolidación de estos campos disciplinares a partir de la apertura democrática en las últimas décadas del siglo XX. Desde los planteos realizados por estos nuevos avances, toda una renovada imagen más compleja y abarcadora de la sociedad puede ser postulada partiendo del análisis de sus grupos dirigentes. Asimismo, estos estudios han despertado nuevos interrogantes sobre períodos poco explorados. Por ello, nuestro propósito se basa en trazar un mapa de los estudios sobre elites en el período reciente y realizar un balance historiográfico de estas contribuciones para vislumbrar las herramientas utilizadas y los enfoques y perspectivas priorizados. Este itinerario, aunque parcial y fragmentario, busca exhibir los puntos de contacto entre las producciones argentinas y las historiografías de otras latitudes, y ha seleccionado el repertorio de investigaciones entre aquéllas que priorizan su mirada sobre las elites políticas, económicas y sociales a lo largo del siglo XX.During the past decades a deep renovation and expansion of studies on élites and leader groups in Argentina have taken place.

    In the inbred HNI-II strain of Oryzias sakaizumii, Dmy and Gsdf are expressed in XY gonads from Stages 35 and 36, respectively, similarly to the inbred Hd-rR strain of Oryzias latipes. However, Dmrt1 respectively becomes detectable at Stage 36 and 5 days post hatching (dph) in the two strains. In XX HNI-II embryos, 17α-methyltestosterone (MT) induces Gsdf mRNA from Stage 36, accompanied by complete sex-reversal in all treated individuals (MT, 10 ng/mL), while Dmrt1 mRNA was first detectable at 5 dph. In XX d-rR, MT induced Gsdf mRNA expression and sex-reversal in only some of the treated individuals. Together, these results suggest the testis differentiation cascade in XY individuals differs between the HNI-II and Hd-rR strains. In addition, it is suggested that androgen-induced XX sex-reversal proceeds via an androgen-Gsdf-Dmrt1 cascade and that Gsdf plays an important role in sex-reversal in medaka.

    Visual illusions explore the limits of sensory processing and provide an ideal testbed to study perception. Size illusions - stimuli whose size is consistently misperceived - do not only result from sensory cues, but can also be induced by cognitive factors, such as social status. Here we investigate, whether the ecological relevance of biological motion can also distort perceived size. We asked observers to judge the size of point-light walkers (PLWs), configurations of dots whose movements induce the perception of human movement, and visually matched control stimuli (inverted PLWs). We find that upright PLWs are consistently judged as larger than inverted PLWs, while static point-light figures do not elicit the same effect. We also show the phenomenon using an indirect paradigm: observers judged the relative size of a disc that followed an inverted PLW larger than a disc following an upright PLW. We interpret this as a contrast effect: The upright PLW is perceived larger and thus the subsequent disc is judged smaller. Together, these results demonstrate that ecologically relevant biological-motion stimuli are perceived larger than visually matched control stimuli. Our findings present a novel case of illusory size perception, where ecological importance leads to a distorted perception of size.

    Full Text Available Today’s clothing industry is based on a system where clothes are made in ready-to-wear sizes and meant to fit most people. Studies have pointed out that consumers are discontent with the use of these systems: size designations are not accurate enough to find clothing that fits, and different sizes are poorly available. This article discusses in depth who these consumers are, and which consumer groups are the most dissatisfied with today’s sizing systems. Results are based on a web survey where 2834 Nordic consumers responded, complemented with eight in-depth interviews, market analysis on clothing sizes and in-store trouser size measurements. Results indicate that higher shares of the consumers who have a body out of touch with the existing beauty ideals express discontentment with the sizing systems and the poor selection available. In particular, large women, very large men, and thin, short men are those who experience less priority in clothing stores and have more difficulties in finding clothes that fit. Consumers tend to blame themselves when the clothes do not fit their bodies, while our study points out that the industry is to blame as they do not produce clothing for all customers.

    Size scaling in cavitation erosion is a major problem confronting the design engineers of modern high speed machinery. An overview and erosion data analysis presented in this paper indicate that the size scale exponent n in the erosion rate relationship as a function of the size or diameter can vary from 1.7 to 4.9 depending on the type of device used. There is, however, a general agreement as to the values of n if the correlations are made with constant cavitation number.

    2007-01-01

    Here is a compendium of fundamental problem formulations of analog design centering and sizing. It provides a differentiated knowledge about the many tasks of analog design centering and sizing. In particular, coverage formulates the worst-case problem. The book stands at the interface between process technology and design technology, detailing how the two are required to reach a solution. It presents a mathematically founded description based on numerical optimization and statistics. This volume will enable analog and mixed-signal designers to assess CAD solution methods that are presented to them as well as help developers of analog CAD tools to formulate and develop solution approaches for analog design centering and sizing.

  1. Cell size, genome size and the dominance of Angiosperms

    Angiosperms are capable of maintaining the highest rates of photosynthetic gas exchange of all land plants. High rates of photosynthesis depends mechanistically both on efficiently transporting water to the sites of evaporation in the leaf and on regulating the loss of that water to the atmosphere as CO2 diffuses into the leaf. Angiosperm leaves are unique in their ability to sustain high fluxes of liquid and vapor phase water transport due to high vein densities and numerous, small stomata. Despite the ubiquity of studies characterizing the anatomical and physiological adaptations that enable angiosperms to maintain high rates of photosynthesis, the underlying mechanism explaining why they have been able to develop such high leaf vein densities, and such small and abundant stomata, is still incomplete. Here we ask whether the scaling of genome size and cell size places a fundamental constraint on the photosynthetic metabolism of land plants, and whether genome downsizing among the angiosperms directly contributed to their greater potential and realized primary productivity relative to the other major groups of terrestrial plants. Using previously published data we show that a single relationship can predict guard cell size from genome size across the major groups of terrestrial land plants (e.g. angiosperms, conifers, cycads and ferns). Similarly, a strong positive correlation exists between genome size and both stomatal density and vein density that together ultimately constrains maximum potential (gs, max) and operational stomatal conductance (gs, op). Further the difference in the slopes describing the covariation between genome size and both gs, max and gs, op suggests that genome downsizing brings gs, op closer to gs, max. Taken together the data presented here suggests that the smaller genomes of angiosperms allow their final cell sizes to vary more widely and respond more directly to environmental conditions and in doing so bring operational photosynthetic

    Glass fibre reinforced polymer composites are widely used for industrial and engineering applications which include construction, aerospace, automotive and wind energy industry. During the manufacturing glass fibres, they are surface-treated with an aqueous solution. This process and the treated...... surfaces are called sizing. The sizing influences the properties of the interface between fibres and a matrix, and subsequently affects mechanical properties of composites. In this work the sizing of commercially available glass fibres was analysed so as to study the composition and chemical structures....... Soxhlet extraction was used to extract components of the sizing from the glass fibres. The glass fibres, their extracts and coated glass plates were analysed by Thermo-Gravimetric Analysis combined with a mass spectrometer (TGA-MS), and Attenuated Total Reflectance Fourier Transform Infrared (ATR...

    The structural origin of the size of the 11 nm nucleosomal disc is addressed. On the nanometer length-scale the organization of DNA as chromatin in the chromosomes involves a coiling of DNA around the histone core of the nucleosome. We suggest that the size of the nucleosome core particle...... is dictated by the fulfillment of two criteria: One is optimizing the volume fraction of the DNA double helix; this requirement for close-packing has its root in optimizing atomic and molecular interactions. The other criterion being that of having a zero strain-twist coupling; being a zero-twist structure......-pairs of the linker-DNA is included the estimate of the size of an ideal nucleosome is in close agreement with the experimental numbers. Interestingly, the size of the nucleosome is shown to be a consequence of intrinsic properties of the DNA double helix....

  6. Size scaling of static friction.

    2013-02-22

    Sliding friction across a thin soft lubricant film typically occurs by stick slip, the lubricant fully solidifying at stick, yielding and flowing at slip. The static friction force per unit area preceding slip is known from molecular dynamics (MD) simulations to decrease with increasing contact area. That makes the large-size fate of stick slip unclear and unknown; its possible vanishing is important as it would herald smooth sliding with a dramatic drop of kinetic friction at large size. Here we formulate a scaling law of the static friction force, which for a soft lubricant is predicted to decrease as f(m)+Δf/A(γ) for increasing contact area A, with γ>0. Our main finding is that the value of f(m), controlling the survival of stick slip at large size, can be evaluated by simulations of comparably small size. MD simulations of soft lubricant sliding are presented, which verify this theory.

    Full Text Available El objeto de este ensayo sobre la derecha radical española es analizar la vía emprendida por el conservadurismo español desde su adhesión a un liberalismo oligárquico, característico de comienzos del siglo XX, a la formación de una derecha antiliberal que culmina en el fascismo durante la segunda república. En este camino hacia posiciones antidemocráticas, corporativas y autoritarias jugará un papel fundamental la recepción del pensamiento antiliberal francés desde el neotradicionalismo de acción Francesa hasta los movimientos fascistas impulsados por Georges Valois y continuados por alguno de sus discípulos en años posteriores. La relación entre ese pensamiento antiliberal de raíz francesa y la evolución fascistizante de la derecha española será el núcleo central de este trabajo. El artículo se estructura en tres grandes partes: en la primera estudiamos los orígenes del pensamiento antiliberal europeo a partir de dos aspectos fundamentales: 1. la crisis de la conciencia europea a finales del siglo XIX que se tradujo en la aparición de un conjunto de elementos ideológicos antiliberales, nacionalistas y corporativos entre los grupos conservadores de Europa, caldo de cultivo de un pensamiento de derecha radical que culminaría con los fascismos. 2. la Primera Guerra mundial y sus consecuencias que engendraron un mundo nuevo polarizado alrededor del bolchevismo y el fascismo. El pensamiento antiliberal, nacionalista, antidemocrático y corporativo se extiende por toda Europa e impregna de diversas maneras a los grupos conservadores europeos empujándoles a posiciones cada vez más autoritarias y dictatoriales, proceso que algunos historiadores han denominado la «fascistización» de la derecha europea. En segundo lugar, analizamos la formación de la derecha radical española desde sus inicios a comienzos del siglo xx hasta la dictadura de miguel Primo de rivera haciendo hincapié en la contribución del pensamiento

Este artículo proporciona una visión general sobre ellos resaltando sus diferencias notorias: Ie La Triple Alianza de 1923 unió a los grupos radicales para conquistar por la fuerza la independencia de Cataluña, Euskadi y Galicia contra la España de la Restauración. 2e La Galeuzca de 1933 fue un pacto moderado encaminado a consolidar, en el caso catalán, o conseguir, en los casos vasco y gallego, sus Estatutos de autonomía dentro de la II República. 3Q Los diversos proyectos de Galeuzca en el exilio, sobre todo en América en los años 1944-1946, tuvieron como denominador común la defensa del derecho de autodeterminación de esos tres pueblos en una hipotética III República española de carácter confederal. 4S La Declaración de Barcelona de 1998 concibe a España como un Estado plurinacional y propugna la reforma del actual Estado de las autonomías para dotar de mayor autogobierno a esas nacionalidades. Los tres primeros pactos tuvieron una vida efímera y fracasaron absolutamente debido a la heterogeneidad de sus miembros y a su nula incidencia en la política española. De ahí que, históricamente, el valor de tales alianzas trilatérales haya sido mucho más testimonial que real. Hasta el momento, esto mismo ha sucedido con la Declaración de Barcelona, que lleva camino de ser una nueva experiencia fallida, al igual que sus precursoras. Palabras Clave.

  9. Genome Size and Species Diversification.

    Kraaijeveld, Ken

    2010-12-01

    Theoretically, there are reasons to believe that large genome size should favour speciation. Several major factors contributing to genome size, such as duplications and transposable element activity have been proposed to facilitate the formation of new species. However, it is also possible that small genome size promotes speciation. For example, selection for genome reduction may be resolved in different ways in incipient species, leading to incompatibilities. Mutations and chromosomal rearrangements may also be more stably inherited in smaller genomes. Here I review the following lines of empirical evidence bearing on this question: (i) Correlations between genome size and species richness of taxa are often negative. (ii) Fossil evidence in lungfish shows that the accumulation of DNA in the genomes of this group coincided with a reduction in species diversity. (iii) Estimates of speciation interval in mammals correlate positively with genome size. (iv) Genome reductions are inferred at the base of particular species radiations and genome expansions at the base of others. (v) Insect clades that have been increasing in diversity up to the present have smaller genomes than clades that have remained stable or have decreased in diversity. The general pattern emerging from these observations is that higher diversification rates are generally found in small-genome taxa. Since diversification rates are the net effect of speciation and extinction, large genomes may thus either constrain speciation rate, increase extinction rate, or both. I argue that some of the cited examples are unlikely to be explained by extinction alone.

    The genome sizes of a Begonia collection comprising 37 species and 23 hybrids of African, Asiatic, Middle American, and South American origin were screened using flow cytometry. Within the collection, 1C values varied between 0.23 and 1.46 pg DNA. Genome sizes were, in most cases, not positively correlated with chromosome number, but with pollen size. A 12-fold difference in mean chromosome size was found between the genotypes with the largest and smallest chromosomes. In general, chromosomes from South American genotypes were smaller than chromosomes of African, Asian, or Middle American genotypes, except for B. boliviensis and B. pearcei. Cytological chromosome studies in different genotypes showed variable chromosome numbers, length, width, and total chromosome volume, which confirmed the diversity in genome size. Large secondary constrictions were present in several investigated genotypes. These data show that chromosome number and structure exhibit a great deal of variation within the genus Begonia, and likely help to explain the large number of taxa found within the genus.

De este modo se verá que los dioses, sus aspectos y funciones, han recibido un tratamiento prioritario al ser el objeto principal de las fuentes, dejándose de lado a los ancianos reales y los temas prosaicos. Las más desfavorecidas han sido las mujeres, de las que sólo se destaca su labor como parteras, curanderas, etc. y su faceta sobrenatural. Finalmente, el conocimiento que se tiene de unos y de otras se desprende de la comparación con sus homólogas divinas.In the following text I will explain the studies done in relation to eldery mesoamerican people, particularly prehispanic Mayan women, all through the 20th century to the beginning of the 21st century in the fields of History, Archaeology, Anthropology, Epigraphy, and Iconography, seen from the point of view of age and gender, and parting from the general to specifics. In this manner, we will see that the gods, their appearance, and their functions have received privileged treatment in these sources, leaving aside the real elders, and prosaic topics. Women have received the least favourable treatment, being only their work as midwives and healers, and their link to the supernatural what has been noticed. Finally, the knowlege that we have about women and men is the result of the comparison with their gods.

    Full Text Available The problems of large-scale migration of population in contemporary Russia have deep historical roots. The author analyzes the research experience of migration processes in pre-revolutionary Russia and revealed key features and results of the migration of this period. The researchers of the pre-revolutionary period considered colonization as the process of settlement, peculiar to any historical situation; the process of migration from densely populated areas to places where they have been specifically populated and heavily adapted to the conditions of life. The article based on archival and published sources considers the process of population movement in the XIX – first half of the XX centuries in Kalmykia, associated with the crisis of the peasant economy, overpopulation of the Black earth provinces of European Russia and the high density of the rural population and low allotments. The special attention is given to the issue of land in the Kalmyk steppes of Astrakhan province, associated with the policy of the exemption of pasture and hay lands of the Russian state. The problems of colonization and resettlement are considered in close connection with the agricultural and other socio-economic issues. The government policy on resettlement was twofold. Initially, the leadership spoke out against the unauthorized resettlement of Russian peasants, but in the end gradually legalized the latter. The government sought to improve the socio-economic situation of Russian peasants at the expense of resettlement in the Kalmyk land. At the same time the state allegedly took into account the interests of indigenous people and sought support among the Kalmyk noyons (princes for its policies in the Kalmyk steppe. The resettlement process took place in stages and the process of penetration in the foreign language environment of the peasant-migrant had its own peculiarities due to the specific nature of the region, traditions and customs of the steppe nomads

    Chimerism is the presence of two or more genetically distinct cell populations in one organism. Here, we reported the identification of dispermic chimerism in a 25-year-old male. Blood grouping was performed with standard gel centrifugation test cards. ABO and HLA-A,-B,-C,-DRB1 and -DQB1 loci genotyping was determined with PCR sequence-based typing. A quantitative analysis of dual red cells populations was measured by flow cytometer. The karyotype was analyzed by G-banded chromosomes. Short tandem repeat (STR) analysis was performed on blood, buccal mucosal and hair shafts samples. A mixed-field agglutination with anti-B antibody was observed with gel centrifugation tests, which showed a double populations of O and B groups RBCs. Two groups RBCs were also observed by flow cytometer with nearly 90% O group cells and 10% B group cells. The normal O01,O02,B101 alleles were identified in DNA sample of the proband. STR analysis revealed three alleles for D8S1179,D3S1358,TH01,D13S317,D16S539,D2S1338,D19S433,TPOX and D18S51 loci. HLA-DRB1 and -DQB1 loci had three alleles and a karyotypic mosaic was found with 60% 46, XY and 40% 46, XX karyotype in the proband. In all studies, the third allele was attributable to a dual paternal contribution. A individual with dispermic chimerism was identified, which would generate by fertilization of an oocyte and the corresponding second polar body by two different sperms.

Este papel nunca estuvo desligado de su lucha por el derecho de las mujeres a educarse, teniendo en cuenta que la Modernidad y la introducción de la mujer al mundo laboral le planteaban nuevos retos y le abrían nuevas perspectivas educativas. Si bien el lugar de la mujer en la sociedad seguía basándose en una visión determinista, que permanece hoy en algunos sectores de la sociedad, María Rojas no solo tenía esa perspectiva de mujer moderna, sino que tomaba la palabra en representación de las mujeres, rompiendo paradigmas e impulsando nuevas ideas en torno a ellas.

Despite the woman’s place in society was based on a deterministic view that is still seen in our society, María Rojas not only had the idea of a modern woman but raised her voice on behalf of women, breaking paradigms and promoting new ideas around women

El método de enseñanza que se desarrolla en este artículo engloba tres modelos, que Aurelio Usón Jaeger califica como: activa, paidocéntrica y vitalista. La enseñanza activa, caracterizada por una metodología que se basa en la participación eficaz y en el desarrollo constante del alumno, con la cual éstos aprenden a medida que van haciendo, siendo especialmente importante la observación de los seres y procesos naturales “invivo”, y la experimentación mediante la realización de diversas y sencillas experiencias. La enseñanza paidocéntrica, en la que los contenidos científicos están más en sintonía con los intereses del niño, su capacidad intelectual y su particular forma de percibir la naturaleza. Por último, la enseñanza vitalista se centra en inculcar unos valores educativos múltiples, que sean preparatorios y, a su vez, útiles para los niños en su vida ulterior y en su más amplio sentido, como sería la adquisición del hábito de indagación científica (Usón, 2003, p.100.
