    Full Text Available Descripción morfológica de las estructuras reproductivas de Austromegabalanus psittacus en dos periodos de maduración sexual. Se determinó que es un organismo hermafrodita que transfiere sus espermatozoides mediante un órgano intromitente o pene. El aparato reproductor masculino consta de testículos organizados en acinos que se distribuyen arboriformemente, dos conductos deferentes que se unen en la base del pene para formar el conducto eyaculador. El aparato reproductor femenino consiste principalmente en un ovario sacular que rodea al resto del cuerpo y se encuentra adherido a través de musculatura a la base de las placas operculares. Se organiza internamente en sacos acinares elongados que contienen ovogonias y ovocitos previtelogénicos adheridos a su pared y vitelogénicos y maduros libres dentro del lumen. Se observaron diferencias notorias en los ovarios entre los organismos recolectados en septiembre y octubre. En septiembre presentaron coloración amarillenta y en su interior se encontraron dos estructuras compactas denominadas lamelas ovígeras en cuyo interior se observaron ovocitos fecundados, embriones en diferentes estados de desarrollo y nauplius libres en la cavidad corporal; en octubre los ovarios son gruesos, blanquecinos y con gran cantidad de fluido lechoso en su interior.

    In the current study, we examined for the first time, the potential for adult neurogenesis throughout the brain of the Congo African grey parrot ( Psittacus erithacus ) and Timneh grey parrot ( Psittacus timneh ) using immunohistochemistry for the endogenous markers proliferating cell nuclear antigen (PCNA), which labels proliferating cells, and doublecortin (DCX), which stains immature and migrating neurons. A similar distribution of PCNA and DCX immunoreactivity was found throughout the brain of the Congo African grey and Timneh grey parrots, but minor differences were also observed. In both species of parrots, PCNA and DCX immunoreactivity was observed in the olfactory bulbs, subventricular zone of the lateral wall of the lateral ventricle, telencephalic subdivisions of the pallium and subpallium, diencephalon, mesencephalon and the rhombencephalon. The olfactory bulb and telencephalic subdivisions exhibited a higher density of both PCNA and DCX immunoreactive cells than any other brain region. DCX immunoreactive staining was stronger in the telencephalon than in the subtelencephalic structures. There was evidence of proliferative hot spots in the dorsal and ventral poles of the lateral ventricle in the Congo African grey parrots at rostral levels, whereas only the dorsal accumulation of proliferating cells was observed in the Timneh grey parrot. In most pallial regions the density of PCNA and DCX stained cells increased from rostral to caudal levels with the densest staining in the nidopallium caudolaterale (NCL). The widespread distribution of PCNA and DCX in the brains of both parrot species suggest the importance of adult neurogenesis and neuronal plasticity during learning and adaptation to external environmental variations.

    2016-11-29

    A named symposium to honor Dr. Mario J. Molina was held 10–14 January 2016, as part of the 96th American Meteorological Society (AMS) Annual Meeting in New Orleans, Louisiana. Dr. Molina first demonstrated that industrially produced chlorofluorocarbons (CFCs) decompose in the stratosphere and release chlorine atoms, leading to catalytic ozone destruction. His research in stratospheric chemistry was instrumental to the establishment of the 1987 United Nations Montreal Protocol to ban ozone-depleting substances worldwide. Dr. Molina’s contributions to preserving the planet Earth not only save the atmospheric ozone layer, but also protect the climate by reducing the emissions of greenhouse gases. He was awarded the 1995 Nobel Prize in Chemistry for his pioneering research in understanding the stratospheric ozone loss mechanism. In 2013, President Barack Obama announced Dr. Molina as a recipient of the Presidential Medal of Freedom. The 2016 AMS Molina Symposium honored Dr. Molina’s distinguished contributions to research related to atmospheric chemistry. The symposium contained an integrated theme related to atmospheric chemistry, climate, and policy. Dr. Molina delivered a keynote speech at the Symposium. The conference included invited keynote speeches and invited and contributed oral and poster sessions, and a banquet was held on Tuesday January 12, 2016. The symposium covered all aspects of atmospheric chemistry, with topics including (1) Stratospheric chemistry, (2) Tropospheric chemistry, (3) Aerosol nucleation, growth, and transformation, (4) Aerosol properties, (5) Megacity air pollution, and (6) Atmospheric chemistry laboratory, field, and modeling studies. This DOE project supported 14 scientists, including graduate students, post docs, junior research scientists, and non-tenured assistant professors to attend this symposium.

    Full Text Available Stomach contents were examined from 102 banded puffer, Colomesus psittacus (Tetraodontidae, caught from intertidal mangrove creeks at diurnal neap tides between June and September, 1997 (early dry season near Bragança (north Brazil. The study found that C. psittacus were specialized predators of Cirripedia (Balanus spp. and Brachyuran crabs (Uca spp., Pachygrapsus gracilis (mean: 58 and 38% by dry weight, respectively, emphasizing a short food chain in the mangrove system. Cirripedia and Brachyura dominated the diet in all size classes, however, the prey spectrum narrowed with fish size. The mean daily consumption of Cirripedia and Brachyura was 6.2% body weight of C. psittacus. On average C. psittacus consumed 100.3 g.ha-1.d-1 of Cirripedia and 178.7 g.ha-1.d-1 of Brachyura (wet weight. The predation on Brachyuran crabs - a significant driver of fluxes of organic matter and energy in the system - provides C. psittacus with an important ecological function in the mangrove food web. A plant-animal interaction is proposed where C. psittacus exerts a mutually beneficial cleaning function on the Aufwuchs (Cirripedia and associated epibiota of Rhizophora mangle stilt roots. Our results and those of other studies suggest that C. psittacus encounter optimum foraging conditions in the mangrove at high inundations at daylight (spring tide-day whereas darkness and low inundations are linked to poor foraging conditions (neap tide-night. The C. psittacus resource could be used as an alternative income in the region in terms of i sustainable catch and filet processing for exports to East Asia, ii developing certified aquaculture methods for breeding puffers for the aquarium trade.

    1997-03-01

    The authors evaluated the ontogenetic performance of a grey parrot (Psittacus erithacus) on object permanence tasks designed for human infants. Testing began when the bird was 8 weeks old, prior to fledging and weaning. Because adult grey parrots understand complex invisible displacements (I. M. Pepperberg & F. A. Kozak, 1986), the authors continued weekly testing until the current subject completed all of I. C. Uzgiris and J. Hunt's (1975) Scale 1 tasks. Stage 6 object permanence with respect to these tasks emerged at 22 weeks, after the bird had fledged but before it was completely weaned. Although the parrot progressed more rapidly overall than other species that have been tested ontogenetically, the subject similarly exhibited a behavioral plateau part way through the study. Additional tests, administered at 8 and 12 months as well as to an adult grey parrot, demonstrated, respectively, that these birds have some representation of a hidden object and understand advanced invisible displacements.

  16. Social isolation shortens telomeres in African Grey parrots (Psittacus erithacus erithacus.

    Directory of Open Access Journals (Sweden)

    Denise Aydinonat

    Full Text Available Telomeres, the caps of eukaryotic chromosomes, control chromosome stability and cellular senescence, but aging and exposure to chronic stress are suspected to cause attrition of telomere length. We investigated the effect of social isolation on telomere length in the highly social and intelligent African Grey parrot (Psittacus erithacus erithacus. Our study population consisted of single-housed (n = 26 and pair-housed (n = 19 captive individuals between 0.75 to 45 years of age. Relative telomere length of erythrocyte DNA was measured by quantitative real-time PCR. We found that telomere length declined with age (p<0.001, and socially isolated parrots had significantly shorter telomeres compared to pair-housed birds (p<0.001 - even among birds of similar ages. Our findings provide the first evidence that social isolation affects telomere length, which supports the hypothesis that telomeres provide a biomarker indicating exposure to chronic stress.

  17. Variation in phenolic compounds of Ugni molinae populations and their potential use as antioxidant supplement

    Full Text Available In the present work we carried out a comparative study of total phenolic contents and antioxidant capacity of aqueous leaf extracts of Ugni molinae Turcz., Myrtaceae (infusion and Soxhlet extracted prepared from continent and Juan Fernández Island samples. The results revealed that total phenol content (TPC, tannins (TTC and flavonoids (TFC for U. molinae extracts (infusion and Soxhlet extracts from island leaves were 38.5, 56.7 and 37.5% higher than those obtained with leaves from the continent, respectively. Also, HPLC profiles showed important differences between U. molinae populations. In vitro antioxidant capacity (scavenging of DPPH radical for 1% infusion and aqueous extract (Soxhlet method of U. molinae from island samples, was 15% greater than from continent samples. Further, in vivo impact of U. molinae intake (1% infusion was studied in plasma samples obtained from healthy volunteers. Participants that consumed tea prepared with leaves from island population showed higher TBARS reduction and plasma antioxidant capacity (TEAC-CUPRAC than those who consumed tea prepared with leaves from continental population. The conditions of the territory in which U. molinae populations growth could explain the differences in their composition and activity. According to results, island U. molinae populations could be an important source of study for the development of an antioxidant supplement, and thereby contribute to the use of this species that has becoming an ecological problem in the island.

    2011-07-01

    A study of ultrasonic enhancement in the extraction of bioactive principles from Quillaja Saponaria Molina (Quillay) is presented. The effects influencing the extraction process were studied through a two-level factorial design. The effects considered in the experimental design were: granulometry, extraction time, acoustic Power, raw matter/solvent ratio (concentration) and acoustic impedance. It was found that for aqueous extraction the main factors affecting the ultrasonically-assisted process were: granulometry, raw matter/solvent ratio and extraction time. The extraction ratio was increased by Ultrasonics effect and a reduction in extraction time was verified without any influence in the product quality. In addition the process can be carried out at lower temperatures than the conventional method. As the process developed uses chips from the branches of trees, and not only the bark, this research contributes to make the saponin exploitation process a sustainable industry.

    Full Text Available The ecosystems of the Mediterranean interior dryland of Chile, dominated by an espinal agroecosystem of Acacia caven (Molina Molina, show low productivity as a result of soil degradation. The objective of this study was to evaluate litter decomposition of A. caven and Lolium multiflorum Lam. in espinal ecosystems: well preserved (Wp 50 to 80%, typical (Pd 25 to 50%, and degraded (De with 10 to 25% cover. During 420 d and starting in April 2004 until August 2005, weight loss in litter bags and chemical composition (hemicellulose, cellulose, lignin, non-structural components, ash, N, C, C/N ratio, and P were determined by using near infrared reflectance spectroscopy (NIRS and the Van Soest protocol. Weight loss ranged from 31 to 52% in L. multiflorum and 26 to 40% in A. caven after 420 d. During the chemical decomposition process of L. multiflorum, cellulose degradation was relevant in the labile phase while lignin was important in the recalcitrant phase. On the other hand, non-structural components and cellulose were degraded in the labile phase and lignin in the recalcitrant stage for A. caven. Moreover, both litters improved N concentration during the decomposition process. Espinal ecosystems with higher canopy cover (Pd and Wp had a positive influence, and showed early effects during the decomposition process, especially in the De espinal ecosystem, probably because of the microenvironmental conditions it generated. A better knowledge of the dynamics of litter decomposition in ecosystems was achieved by using both techniques: litter bags and NIRS.Los ecosistemas del secano interior mediterráneo de Chile presentan una baja productividad debido a la degradación de los suelos, dominados por un agroecosistema espinal de Acacia caven (Molina Molina.

    Full Text Available Aspidogastrea are globally-distributed parasites of the class Trematoda, which have been described as pathogens of a range of aquatic organisms, in marine and freshwater environments. The principal morphological characteristic of the group is an adhesive ventral disc, which is responsible for fixing the parasite to the host organism. In this study, 112 specimens of Colomesus psittacus from the municipality of Cametá, in the state of Pará (Brazil, were necropsied. Platyhelminthes of the genus Rohdella attached to the mucous membrane of the fish's intestine by the adhesive disc were observed. Fragments of parasitized tissue were fixed in Davidson solution and then processed and stained with hematoxylin-eosin. Other fragments were fixed in glutaraldehyde, processed and observed under a scanning electron microscope. The prevalence of the parasite was 76.4%, mean intensity of infection was 8.0 and mean abundance was 6.2. The parasitism provoked chronic enteritis with diffused inflammatory infiltration. The adherence of the parasite to the mucous membrane of the intestine resulted in strangulation and hyperplasia of the region, as well as causing hypertrophy of the muscle of the mucous membrane. The present study describes the anatomopathological and ultrastructural aspects of the parasitism of the intestine of C. psittacus by Rohdella sp.Os Aspidogastreas são parasitos da classe Trematoda, distribuídos globalmente e têm sido descritos como patógenos em uma gama de organismos aquáticos de ambientes marinhos e de água doce.

    The aim of the study was to characterize atherosclerotic changes in African grey parrots (Psittacus erithacus) and Amazon parrots (Amazona spp.) by histochemical and immunohistochemical methods. Samples of the aorta ascendens and trunci brachiocephalici from 62 African grey parrots and 35 Amazon parrots were stained by hematoxylin and eosin and Elastica van Gieson for grading of atherosclerosis in these birds. Four different stages were differentiated. The incidence of atherosclerosis in the examined parrots was 91.9% in African grey parrots and 91.4% in Amazon parrots. To evaluate the pathogenesis in birds, immunohistochemical methods were performed to demonstrate lymphocytes, macrophages, smooth muscle cells, and chondroitin sulfate. According to the missing lymphocytes and macrophages and the absence of invasion and proliferation of smooth muscle cells in each atherosclerotic stage, "response-to-injury hypothesis" seems inapplicable in parrots. Additionally, we found alterations of vitally important organs (heart, lungs) significantly correlated with atherosclerosis of the aorta ascendens.

    Suwalsky, Mario; Avello, Marcia

    2014-08-01

    Ugni molinae is an important source of molecules with strong antioxidant activity widely used as a medicinal plant in Southern Chile-Argentina. Total phenol concentration from its fruit extract was 10.64 ± 0.04 mM gallic acid equivalents. Analysis by means of HPLC/MS indicated the presence of the anthocyanins cyanidin and peonidin, and the flavonol quercitin, all in glycosylated forms. Its antioxidant properties were assessed in human erythrocytes in vitro exposed to HClO oxidative stress. Scanning electron microscopy showed that HClO induced an alteration in erythrocytes from a normal shape to echinocytes; however, this change was highly attenuated in samples containing U. molinae extracts. It also had a tendency in order to reduce the hemolytic effect of HClO. In addition, X-ray diffraction experiments were performed in dimyristoylphosphatidylcholine (DMPC) and dimyristoylphosphatidylethanolamine bilayers, classes of lipids preferentially located in the outer and inner monolayers, respectively, of the human erythrocyte membrane. It was observed that U. molinae only interacted with DMPC. Results by fluorescence spectroscopy on DMPC large unilamellar vesicles and isolated unsealed human erythrocyte membranes also showed that it interacted with the erythrocyte membrane and DMPC. It is possible that the location of U. molinae components into the membrane outer monolayer might hinder the diffusion of HClO and of free radicals into cell membranes and the consequent decrease of the kinetics of free radical reactions.

    Full Text Available Antonio Muñoz Molina (Úbeda, 1956 es ya, sin lugar a dudas, uno de los más destacados novelistas españoles contemporáneos. boga en la década que va de 1960 a 1970 al “realismo depurado” y al compromiso ético. La narrativa de Muñoz Molina apela constantemente a los cruces de códigos y al hacerlo va adoptando singulares modulaciones; itinerario que en su recorrido irá dando cuenta de un posicionamiento ideológico frente a los fenómenos derivados de la industria cultural –fenómenos camp y kitsch–, los géneros menores, la intertextualidad y lo intermedial. En esta curva, El jinete polaco significaría un punto de inflexión dentro de la producción narrativa del autor. En ella Muñoz Molina escribe una novela inspirada todavía en un motivo pictórico, pero abandona la astucia narrativa del final sorprendente y combina múltiples peripecias, historias cruzadas, diversos puntos de vista que apuntan a construir algo semejante a lo que Mario Vargas Llosa intuyó en Cien años de soledad de García Márquez, una “novela total”.

The aim of this study was to assess the differences in the phenolic composition and antioxidant capacity of the ethanolic extracts from the leaves of 10 genotypes of U. molinae, that were cultivated under the same soil, climate and agronomical management. Antioxidant activity was assessed by complementary methods (ORAC-Fl, FRAP and DPPH assay), phenolic composition of each extract was analyzed by LC-MS. Phenolic and flavonoid total contents were determined by Folin-Ciocalteu and AlCl3 methods. Significative differences were found by these methods, and ellagitannins, gallic acid derivatives and flavonols were identified as responsible for these differences, showing the influence of the genotype on the phenolic composition of U. molinae leaves.

    A 7-year-old and a 10-year-old Congo African grey parrot (Psittacus erithacus erithacus; parrots 1 and 2, respectively) were evaluated because of neurologic deficits. Parrot 1 had an 8- to 9-month history of lethargy and anorexia, with a recent history of a suspected seizure. Parrot 2 had a 6-month history of decreased activity and vocalizing, with an extended history of excessive water intake; a water deprivation test ruled out diabetes insipidus, and psychogenic polydipsia was suspected. Both birds had ophthalmologic asymmetry, with anisocoria detected in parrot 1 and unilateral blindness in parrot 2. Metal gastrointestinal foreign bodies were observed on whole-body radiographs of both birds, but blood lead concentrations were below the range indicated for lead toxicosis. Findings on CT of the head were consistent with hydrocephalus in both cases. Parrot 1 received supportive care and died 3 months after the diagnosis of hydrocephalus. Parrot 2 was treated with omeprazole and prednisolone for 10 days without any improvement in neurologic deficits; euthanasia was elected, and hydrocephalus was confirmed on necropsy. No underlying or concurrent disease was identified. Hydrocephalus should be considered a differential diagnosis for parrots evaluated because of CNS signs. Computed tomography was an excellent screening tool to diagnose hydrocephalus in these patients. Compared with MRI, CT is more frequently available and offers reduced scanning times, reduced cost, and less concern for interference from metallic foreign bodies.

    To determine the pharmacokinetics and safety of orally administered voriconazole in African grey parrots. 20 clinically normal Timneh African grey parrots (Psittacus erithacus timneh). In single-dose trials, 12 parrots were each administered 6, 12, and 18 mg of voriconazole/kg orally and plasma concentrations of voriconazole were determined via high-pressure liquid chromatography. In a multiple-dose trial, voriconazole (18 mg/kg) was administered orally to 6 birds every 12 hours for 9 days; a control group (2 birds) received tap water. Treatment effects were assessed via observation, clinicopathologic analyses (3 assessments), and measurement of trough plasma voriconazole concentrations (2 assessments). Voriconazole's elimination half-life was short (1.1 to 1.6 hours). Higher doses resulted in disproportional increases in the maximum plasma voriconazole concentration and area under the curve. Trough plasma voriconazole concentrations achieved in the multiple-dose trial were lower than those achieved after administration of single doses. Polyuria (the only adverse treatment effect) developed in treated and control birds but was more severe in the treatment group. In African grey parrots, voriconazole has dose-dependent pharmacokinetics and may induce its own metabolism. Oral administration of 12 to 18 mg of voriconazole/kg twice daily is a rational starting dose for treatment of African grey parrots infected with Aspergillus or other fungal organisms that have a minimal inhibitory concentration for voriconazole treatment. Safety and efficacy of various voriconazole treatment regimens in this species require investigation.

    Full Text Available Abstract Background An avian papillomavirus genome has been cloned from a cutaneous exophytic papilloma from an African grey parrot (Psittacus erithacus. The nucleotide sequence, genome organization, and phylogenetic position of the Psittacus erithacus papillomavirus (PePV were determined. This PePV sequence represents the first complete avian papillomavirus genome defined. Results The PePV genome (7304 basepairs differs from other papillomaviruses, in that it has a unique organization of the early protein region lacking classical E6 and E7 open reading frames. Phylogenetic comparison of the PePV sequence with partial E1 and L1 sequences of the chaffinch (Fringilla coelebs papillomavirus (FPV reveals that these two avian papillomaviruses form a monophyletic cluster with a common branch that originates near the unresolved center of the papillomavirus evolutionary tree. Conclusions The PePV genome has a unique layout of the early protein region which represents a novel prototypic genomic organization for avian papillomaviruses. The close relationship between PePV and FPV, and between their Psittaciformes and Passeriformes hosts, supports the hypothesis that papillomaviruses have co-evolved and speciated together with their host species throughout evolution.

    Full Text Available In general, the work of the Chilean ex Jesuit Juan Ignacio Molina (1740-1829 has not been studied under the light of history of geology. This article attempts to reconstruct the origin and morphology of the ideas in which the Chilean naturalist developed about the internal structure of the Earth. We will see how the geological ideas elaborated by Molina went beyond the scientific reflection. The development of a particular discipline as political economy during the eighteenth century also influenced Juan Ignacio Molina´s thoughts about the internal organization of the Earth, geological processes and the descriptions of the nature of Chilean kingdom in the late eighteenth century.En general, la obra del ex jesuita chileno Juan Ignacio Molina (1740-1829 no ha sido estudiada con profundidad a la luz de la historia de la geología.

Se verá cómo las ideas geológicas desarrolladas por Molina fueron más allá de la simple reflexión científica. El desarrollo de una disciplina particular y novedosa como la economía política, también influyó en el tipo de reflexiones que Juan Ignacio Molina desarrolló sobre la organización interior de la Tierra, los procesos geológicos y las descripciones sobre la naturaleza del Reino de Chile a fines del siglo XVIII.

    2014-12-01

    Full Text Available Over the last decade a considerable increase in the number of studies addressing the use of antioxidants from natural sources has led to the identification and understanding of the potential mechanisms of biologically active components. This results from the fact that they can be used to replace synthetic antioxidants commonly used in food. Murtilla (Ugni molinae Turcz is a native berry grown in Chile, and in the present study, the phenolic composition and antioxidant activity of its fruits were studied. Hydroalcoholic extracts of dehydrated fruits from two genotypes of murtilla (Ugni molinae Turcz. were produced. Extracts of wild murtilla and 14-4 genotype fruits had 19.35 and 40.28mg GAE/g for Total Phenolic Compounds, 76.48, and 134.35μmol TEAC/g for DPPH, and 157.04 and 293.99 μmol TEAC/g for ABTS, respectively. Components such as quercetin, epicatechin, and gallic, benzoic and hydrocaffeic acids were identified by CG/MS analysis. All of them showed antioxidant activity. Therefore, it is possible to say that the hydroalcoholic extracts of murtilla have antioxidant potential to be used in lipidic food.

    Calcium (Ca), phosphorus (P), and magnesium (Mg) are important elements for body homeostasis in several diseases associated with imbalances in the plasma concentration of these ions. This is the first published report of reference intervals for Mg in association with Ca and P levels for psittacine species. One milliliter of blood was collected from 26 Hispaniolan parrots (Amazona ventralis) and 24 African grey parrots (Psittacus erithacus). The plasma concentrations of Ca, P, and Mg were determined for each sample. Statistical analyses were performed including all data (analysis 1) and after exclusion of the subjects with Ca > or = 14.00 mg/dl (3.5 mmol) (analysis 2). The data from analysis 1 have a narrower interval than that observed in analysis 2. Following the normality test (Shapiro-Wilk, alpha = 0.05), the univariate and mean procedures were run. For the reference intervals, the lower and upper values were used, after elimination of the outliers calculated by Blom scores from the ranked variables. The analysis 1 references for the Hispaniolans were Ca = 8.80-10.40 mg/dl (2.20-2.60 mmol/L), P = 1.80-4.40 mg/dl (0.58-1.42 mmol/L), Mg = 1.80-3.10 mg/dl (0.74-1.27 mmol/L), and Ca:P ratio = 2.62-5.39; for the African greys analysis 1 references were Ca = 8.20-20.20 mg/dl (2.05-5.05 mmol/L), P = 2.50-5.90 mg/dl (0.81-1.91 mmol/L), Mg = 2.10-3.40 mg/dl (0.82-1.4 mmol/L), and Ca:P ratio = 1.81-3.77. The analysis 2 references for the Hispaniolans were Ca = 8.80-10.30 mg/dl (2.20-2.58 mmol/L), P = 1.80-3.80 mg/dl (0.58-1.23 mmol/L), Mg = 1.90-3.00 mg/dl (0.82-1.07 mmol/L), Ca:P ratio = 2.62-5.39; for the African greys analysis 2 references were Ca = 1.07 mmol/L), Ca:P ratio = 1.67-3.50. The results of this study are important for evaluating Mg concentrations in relation to the Ca and P parameters in psittacines. This information will be particularly helpful for veterinarians evaluating the hypocalcemic syndrome in African grey parrots and other disease processes

    2016-11-01

    Full Text Available The crisis is the political upheaval that accompanied the ascent of Olivares to power. Its repercussions on the religious and literary career of Fr. Gabriel Téllez/Tirso de Molina are examined. The primary documents analysed include the two passages in Téllez’s Historia de la Orden de la Merced (one from the early 1630s. the other revised towards the end of the decade containing his hostile criticism of the struggle between the two groups, Lerma’s associates and those of Olivares. This hostility relates to the sentence issued by the Junta de Reformación (1625 and to be meted out as its response to the notorious case of Fr. Gabriel Téllez oka Tirso de Molina, etc. This connection confirms our seeing Tirso as a notable political victim. Yet in the thirties, Tirso’s position is complex. To offset the clear indications of a major if not terminal disruption to his activity as dramatist, the circumstances attendant on the Parte tercera de las comedias (1634 are examined to show how Fr. Gabriel came to the defence of his creation Tirso de Molina, by ensuring his survival in print. The text of the Junta’s sentence informs us of the reason its judges had to silence the dramatist; it concerns his writing plays which are profane and give bad examples. This information invites us to ask to which plays can the harsh sentence of the Junta refer? The reply to this question forms the main theme of the study. It is argued that La venganza de Tamar is a work seriously involved in the turbulent politics of the succession. This argument is preceded by an essential study on the text as authorized by Tirso and subject to the editorial scrutiny of Lucas de Avila. The nexus of images referring to physical hunger that develops into sexual and political hunger is coordinated with the recurring image of the body, presented in a series of progressively morbid pathological states. The human body receives focus in a spectacular way, as a conspicuous object on

    Full Text Available The present study examines three plays by Tirso de Molina (Amar por señas, El castigo del penséque and Quien calla otorga in which female protagonists in positions of power (or as relatives of those in power use their authority to confuse and deceive the male protagonists, who is a foreigner in their lands. Their position allows them to go beyond the typical deceptions of Tirso’s intrigue comedies (e. g., Don Gil de las calzas verdes. Concretely, they manage to detain the young man physically, to torment him without revealing their identity and to send ambiguous message that keep the male character in uncertainty. However, they are constrained by their sense of honor and it is implied that, after the traditional wedding that ends these plays, the women will no longer have the authority to continue their manipulation.

    Gamma-ray scanning, often referred to as 'column scanning', is a convenient, cost effective, fast, efficient and non-invasive technique to examine internal characteristics of a certain equipment, like alcohol distillation columns, while it is in operation. Column scanning allows to engineers, to study hydraulics tray inside of distillation column in on-line condition. It provides essential data to optimize the performance of columns, extend column run times, to evaluate effects of defective track and to identify maintenance requirements. This knowledge can reduce repair times significantly. In the year 2014, the Environmental Radiological Surveillance Laboratory from Center of Radiation Protection and Hygiene, introduced this service in the 'Hector Molina' Distillery. The diagnosis carried out allowed the detection of some anomalies in its operation. In this work the results obtained during gamma-ray scanning of the column are shown. (Author)

    Full Text Available Background African grey parrots (Psittacus erithacus are kept as pets and are frequently hand-reared. It has been observed that hand-reared African grey parrots may develop behavioral disorders such as feather damaging behavior (FDB. It is well known that chronic stress is involved in behavioral disorders in captive parrots. The main glucocorticoid in birds is corticosterone; its quantification provides information about adrenocortical activity and is considered to be a reliable indicator of stress levels in birds. We analyzed the differences in the excretion of corticosterone metabolites (CM in the droppings of African grey parrots characterized by: 1. different rearing histories (parent rearing vs. hand rearing; and 2. the presence or absence of FDB in hand-reared parrots. Methods A total of 82 African grey parrots that were kept in captivity were considered. According to breeding methods, three groups of birds were defined: 1. The parent-reared (PR parrots included birds kept in pairs (n = 30 pairs with a conspecific partner of the opposite sex. All of these birds were healthy and never showed FDB signs; 2. The healthy hand-reared parrots (H-HR included pet parrots individually kept, that were hand-reared and did not display any sign of FDB (n = 11, 7 males and 4 females; 3. The FDB hand-reared parrot (FDB-HR included pet parrots individually kept, that were hand-reared and displayed FDB (n = 11, 7 males and 4 females. Droppings were collected in the morning over three alternating days in autumn 2014 and spring 2015. The CM were determined using a multi-species corticosterone enzyme immunoassay kit. Split-plot repeated-measure ANOVA was used to examine any differences using group, season and group × season as the main factors. Results Different quantities of CM in droppings were found for the three groups. The mean CM value was 587 ng/g in the PR parrots, 494 ng/g in the H-HR parrots and 1,744 ng/g in the FDB-HR parrots, irrespective of the

    Full Text Available The genus Pyrrhura includes small to medium-sized parakeets, which inhabit both low and dry alongside tall rainforests, mainly in South America. Pyrrhura molinae is still common, year round, in the markedly seasonal forests of western Brazil. This parakeet, as well as most Neotropical parrots, continues to be poorly understood. Hence, in the present study I examined their foraging ecology both in a highly deciduous and in a semi-deciduous forest in western Brazil. In addition, I assessed the relationship between food resource production (flowers and fruits, and the diet of this parakeet. Pyrrhura molinae exhibited a flexible diet consisting of 16 tree species, from which it consumed flowers (three species, seeds (three species, fruit pulp or aril (four species, and both pulp and seeds (six species. Parakeets consumed a wide array of fleshy fruits in the semi-deciduous forest, especially Cecropia pachystachya catkins. Conversely, in the highly deciduous forest they extensively foraged for figs (70% of the diet, in addition to nectar and seeds from dry fruits. Ficus calyptroceras, besides being abundant, bore fruits year round, and was substantially used by parakeets every month. Potentially, by exploiting a diverse set of plant food resources, and particularly due to the substantial use of figs, asynchronously produced, Pyrrhura molinae persists during the long dry season in the markedly seasonal forests of western Brazil.O gênero Pyrrhura é constituido de pequenos periquitos comuns tanto em matas secas quanto úmidas, sobretudo da América do Sul.

    Full Text Available Hypertension is a systemic condition with high morbidity and mortality rates worldwide, which poses an increased risk for cardiovascular diseases. In this study, we demonstrated the antioxidant and vasodilator activity of Ugni molinae Turcz. (Murtilla fruit, a berry native to Chile and proposed models to explain its modulatory mechanism in hypotensive response. Murtilla fruits were cultivated in a germplasm bank and submitted to chemical and biological analyses. The phenolic compounds gallic acid, Catechin, Quercetin-3-β-D-glucoside, Myricetin, Quercetin, and Kaempferol were identified. Murtilla extract did not generate toxic effects on human endothelial cells and had significant antioxidant activity against ROS production, lipid peroxidation, and superoxide anion production. Furthermore, it showed dose-dependent vasodilator activity in aortic rings in the presence of endothelium, whose hypotensive mechanism is partially mediated by nitric oxide synthase/guanylate cyclase and large-conductance calcium-dependent potassium channels. Murtilla fruits might potentially have beneficial effects on the management of cardiovascular diseases.

Microcapsules were produced by water-in-oil emulsion (W/O using a phase of the aqueous maqui leaf extract and gum arabic, and a liquid vaseline phase. Maqui leaf extract antioxidant capacity was 99.66% compared with the aqueous phase of the emulsion at 94.38 and 93.06% for 5% and 15% gum arabic, respectively. The mean yield of maqui leaf extract microencapsulation with 5% gum arabic varied between 38 and 48%, whereas with 15% gum arabic it was 39%. Once the antioxidant microcapsules were formed, mean extract antioxidant capacity ranged between 30 and 35%. Both yields responded similarly to changes in gum arabic concentrations (5% and 15% in the aqueous phase of the emulsion; 5% concentration produced a microcapsule size from 1.0 to 10 urn. Maqui leaf extracts with high phenolic compound levels, which can be stabilized and protected by the microencapsulation process, produce new natural preservative systems as compared with their synthetic counterparts.

    Full Text Available ABSTRACT: The pampas cat Leopardus colocolo (Molina, 1782 is a species of the Felidae family, widely distributed in South America, included on CITES Appendix II and classified as Near Threatened on the IUCN Red List, with population trend decreasing. Based on this information, the objective of this study is to describe morphologically the testes and epididymal ducts of pampas cat. The animal, coming from the Federal University of Mato Grosso Zoo, Brazil, had died after anesthesia procedure and the male reproductive system was dissected to collect the testicles. The samples taken were fragmented and histologically examined. From the microscopic analysis of the testes were identified: vaginal and tunica albuginea, formed by dense connective tissue modeled with large amount of collagen fibers. The tunica albuginea fibrous septa emits into the body. The seminiferous tubules are coiled and coated internally by spermatogenic epithelium consisting of Sertoli cells, surrounded by a basement membrane in the presence of myoid cells. The interstitial tissue between the seminiferous tubules, is composed of loose connective tissue, blood and lymph vessels, and Leydig cells in polyhedral shape. The epididymal ducts showed pseudostratified columnar epithelium with secretory cells of which stereocilia design, situated on a basement membrane filled by myoid cells. This epithelium has principal and basal cells, the main cell design stereocilia toward the lumen of the epididymal duct.

    Full Text Available The novel El jinete polaco by Antonio Muñoz Molina is a highly complex work in which the narrator mixes multiple plotlines in an effort to recreate or remember part of his family past. In the process, the collective memory of the town and people of Mágina (an allegoric space that represents the peasant life of the olive growers of southern Spain appears as a rich and contradictory montage of dreams and failures. And in a third level of discourse, the recent past of Spain also emerges through the main historic al events: the civil war, the protracted military government, and the economic development and current consolidation of democracy. In order to achieve this complex and ambitious narrative project, in El jinete polaco time is not represented as uninterrupted historical timeline but as the rich mixture of the simultaneous experiences of different life courses in terms of both values and cultural patterns in order to understand how the rapid social change affects relations between the various age groups. In other words, time is constructed as a synthesis of the biographical dimension within collective memory and major historical events. This paper seeks to point out the similarities and differences between biographical discourse, collective memory and history.

    Full Text Available Akodon molinae (with 2n = 42-43-44 and an FN = 44 shows a remarkable polymorphism of chromosome 1 in natural and laboratory populations. Specimens 2n = 42, named single homozygotes (SH, have a chromosome pair 1 formed by two large metacentric chromosomes. Specimens 2n = 3, heterozygotes (Ht, have one chromosome 1 and two medium-sized subtelocentric chromosomes, 1a and 1b, which are homologous with the long and short arms of chromosome 1 respectively. Specimens 2n = 44 are double homozygotes (DH, with just two pairs of medium-sized subtelocentric chromosomes, 1a and 1b. Analysis of meiotic metaphases I and II showed that anomalous segregation occurs more frequently in spermatocytes carrying the 1a and 1b chromosomes. This would disturb gametogenesis and other reproductive and developmental processes, producing a marked decrease in viability of DH individuals. There is, as yet, no satisfactory explanation for these phenomena. To investigate structural elements which might explain such segregational anomalies, we have studied bivalent and trivalent synapsis in pachytene spermatocytes from SH, Ht and DH specimens. Of a total of 80 spermatocyte nuclei microspreads, the following results were obtained: of 16 microspreads from two SH individuals, 20 autosomic bivalents plus the XY bivalent were observed; of 48 microspreads from three Ht individuals, 19 autosomic bivalents, 1 trivalent and an XY bivalent were seen; and of the 16 microspreads from two DH individuals, 21 autosomic bivalents plus the XY bivalent were found. Trivalents analysed showed complete pairing between the short arms of 1a and 1b, and having an apparently normal synaptonemal complex (SC with lengths of 1 and 2.8 µm. The trivalent SC showed three telomeric ends, corresponding to arms: q1 and q1a; p1 and q1b; and p1a and p1b, with attachment plates to the nuclear envelope of normal organisation. None of the trivalents showed asynapsis or desynapsis between p1a and p1b, nor an

    This study describes the results of an analysis using Southern blotting, the polymerase chain reaction, and sequencing which shows that the African grey parrot (Psittacus erithacus) lacks the W-chromosomal gene for the alpha subunit of mitochondrial ATP synthase (ATP5A1W). Additional evidence shows that in other psittacines a fragment of the ATP5A1W gene contains five times as many nonsynonymous nucleotide replacements as the homologous fragment of the Z gene. Therefore, whereas in these other psittacines the corresponding ATP5A1Z protein fragment is highly conserved and varies by only a few, moderately conservative amino acid substitutions, the homologous ATP5A1W fragments contain a considerable number of, sometimes highly nonconservative, amino acid replacements. In one of these species, the ringneck parakeet (Psittacula krameri), the ATP5A1W gene is present in an inactive form because of the presence of a nonsense codon. Other changes, possibly leading to an inactive ATP5A1W gene product, involve the substitution of arginine residues by cysteine in the ATP5A1W protein of the mitred conure (Aratinga mitrata) and the blue and gold macaw (Ara ararauna). The data suggest also that although the divergence of the psittacine ATP5A1W and ATP5A1Z genes preceded the origin of the psittacidae, this divergence occurred independently of a similar process in the myna (Gracula religiosa), the outgroup used in this study.

    Paroxetine, a selective serotonin reuptake inhibitor, may be beneficial in the treatment of behavioural disorders in pet birds. The lack of pharmacokinetic data and clinical trials currently limits the use of this drug in clinical avian practice. This paper evaluates the pharmacokinetic properties and potential side effects of single and repeated dosing of paroxetine in Grey parrots (Psittacus erithacus erithacus). Paroxetine pharmacokinetics were studied after single i.v. and single oral dosing, and after repeated oral administration during 1 month. Plasma paroxetine concentrations were determined by liquid chromatography-tandem mass spectrometry. No undesirable side effects were observed during the study. Pharmacokinetic analysis revealed a quick distribution and rapid elimination after i.v. administration. Oral administration of paroxetine HCl dissolved in water resulted in a relatively slow absorption (T(max)=5.9±2.6 h) and a low bioavailability (31±15%). Repeated administration resulted in higher rate of absorption, most likely due to a saturation of the cytochrome P450-mediated first-pass metabolism. This study shows that oral administration of paroxetine HCl (4 mg/kg twice daily) in parrots results in plasma concentrations within the therapeutic range recommended for the treatment of depressions in humans. Further studies are needed to demonstrate the clinical efficacy of this dosage regimen in parrots with behavioural disorders. © 2012 Blackwell Publishing Ltd.

    Full Text Available Feeding habits of the Molina's hog-nosed skunk, Conepatus chinga (Molina, 1782 in the extreme south of Brazil. We analyzed 60 stomachs of road-kills of C. chinga in the extreme south of Brazil. The contents revealed 808 prey parts, including invertebrates (frequency of occurrence - FO = 96.7% and relative abundance - RA = 94.7%, vertebrates (FO = 18.3% and RA = 2.8% and plants (FO = 31.7% and RA = 2.3%. We identified 18 kinds of food, including the invertebrate order Coleoptera which showed the highest FO (86.7% and RA (75.2%. Other important orders were Orthoptera (FO = 35% and RA = 10.4% and Araneae (FO = 41.7% and RA = 4%. The combination of occurrence and abundance of the preys consumed allowed classifying C. chinga as an omnivorous with a predominance of insects, especially Coleoptera, consuming other invertebrates, vertebrates and plants in smaller numbers. Behavioral and morphological adaptations of C. chinga favor the predation of insects, which are preys that offer low physical resistance and are available in all terrestrial environments.

    Comparative anatomical study of the ventral brain arteries of the Pudú pudu (Molina, 1782) with those of the cow. A comparison using the corrosion method was made between Pudú pudu (Molina, 1782) ventral brain arteries and those of the cow. The Pudú's Rete mirabile epidurale rostrale (Nomina Anatomica Veterinaria, 1994) is ventrally formed by branches of the A. maxillaris, and caudally formed by the A. vertebralis. The Hypophysis is surrounded by the Rete mirabile rostrale. The lateral parts are rostrally joined to that gland by a thin vascular bridge and caudally by thick arteries. The Pudú's Circulus arteriosus cerebri asymmetrical, that is, on the right side the A. cerebri rostralis ends in the A. cerebri media. The left-side A. cerebri rostralis irrigates every rostral portion of the encephalon. In the cow, practically the same arteries come out of the Circulus arteriosus cerebri, which is not asymmetrical. The A. cerebri caudalis comes first out of the A. communicans caudalis and then the branches for the Pons, and finally the A. cerebelli rostralis. In this species, there are arterial blocks that are not present in Pudú.

    Diet-tissue isotopic relationships established under controlled conditions are informative for determining the dietary sources and geographic provenance of organisms. We analysed δ 13 C, δ 15 N, and non-exchangeable δ 2 H values of captive African grey parrot Psittacus erithacus feathers grown on a fixed mixed-diet and borehole water. Diet-feather Δ 13 C and Δ 15 N discrimination values were +3.8 ± 0.3 ‰ and +6.3 ± 0.7 ‰ respectively; significantly greater than expected. Non-exchangeable δ 2 H feather values (-62.4 ± 6.4 ‰) were more negative than water (-26.1 ± 2.5 ‰) offered during feather growth. There was no positive relationship between the δ 13 C and δ 15 N values of the samples along each feather with the associated samples of food offered, or the feather non-exchangeable hydrogen isotope values with δ 2 H values of water, emphasising the complex processes involved in carbohydrate, protein, and income water routing to feather growth. Understanding the isotopic relationship between diet and feathers may provide greater clarity in the use of stable isotopes in feathers as a tool in determining origins of captive and wild-caught African grey parrots, a species that is widespread in aviculture and faces significant threats to wild populations. We suggest that these isotopic results, determined even in controlled laboratory conditions, be used with caution.

    Birds are routinely presented to veterinarians for dehydration. Success with these cases ultimately depends on providing replacement fluids and re-establishing fluid homeostasis. Few studies have been done to determine reference ranges for plasma osmolality in birds. The goals of this study were to determine reference values for plasma osmolality in 3 species of parrots and to provide recommendations on fluid selection for replacement therapy in these species. Blood samples were collected from 21 adult Hispaniolan Amazon parrots (Amazona ventralis), 21 Congo African grey parrots (Psittacus erithacus erithacus), and 9 red-fronted macaws (Ara rubrogenys), and were placed into lithium heparin containers. Plasma osmolality was measured in duplicate with a freezing point depression osmometer. Summary statistics were computed from the average values. Reference ranges, calculated by using the robust method, were 288-324, 308-345, and 223-369 mOsm/kg in African grey parrots, Hispaniolan Amazon parrots, and red-fronted macaws, respectively. The mean +/- SD values were 306 +/- 7, 327 +/- 7, and 304 +/- 18 mOsm/kg in African grey parrots, Hispaniolan Amazon parrots, and red-fronted macaws, respectively. Comparisons with osmolality values in mammals and values previously reported for psittacine bird species suggest that plasma osmolality is slightly higher in parrots than in mammals, species-specific differences exist, and differences between reported values occur. Overall, fluids with an osmolarity close to 300-320 mOsm/L, such as Normosol-R, Plasmalyte-R, Plasmalyte-A, and NaCl 0.9%, can be recommended in parrots for fluid replacement therapy when isotonic fluids are required.

    An oil model system was used to analyze the antioxidant activity of Chilean fruit extracts and to determine their odor sensory effect. Hydroalcoholic extracts from wild and 14-4 genotype murtilla (Ugni molinae Turcz.) fruit were assessed by the Response Surface Methodology. The optimal conditions for producing high total phenolic-content extracts were 49.5% (v/v) ethanol at 30 ºC, which yielded 18.39 and 26.14 mg GAE·g−1 dry matter, respectively. The optimized extracts were added to a lipid model system and evaluated via the Schaal Oven Test. After 96 hours, 150 and 200 mg·kg−1 oil of the wild and 14-4 genotype extracts, respectively, showed an antioxidant capacity similar to TBHQ (200 mg·kg−1 oil) in terms of peroxide values and odor. Thus, murtilla fruit extracts are a natural source of antioxidants for protecting lipidic foods, such as soybean oil. [es

    The aim of the present study was to determine (1) the polyphenolic profile (phenolic acids, flavonoids and anthocyanins), (2) the antioxidant using four different methodologies (DPPH, ABTS, FRAP and FIC) and (3) the antibacterial properties of maqui berry [Aristotelia chilensis (Molina) Stuntz] (MB) grown in Chile. The HPLC analysis of MB showed a total of 19 polyphenolic compounds identified as anthocyanins (eight compounds), flavonols (10 compounds) and ellagic acid. Delphinidin derivatives were the predominant anthocyanins while quercetin derivatives were the predominant flavonols. MB showed an antioxidant activity measured with DPPH, ABTS, FRAP and FIC methods of 28.18, 18.66, 25.22 g Trolox equivalent kg(-1) and 0.12 g ethylenediaminetetraacetic acid equivalent kg(-1) , respectively. With regard to the antibacterial activity, all strains tested were affected by MB. Aeromonas hydrophila and Listeria innocua showed the highest sensitivity to maqui berry extracts with MIC values of 40 and a 50 mg mL(-1) , respectively. The results suggest that maqui berry has a great potential to be employed in the food industry as potential food ingredient to functional food development or as bio-preservative. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

Both had extensive mycorrhizal arbuscular symbiosis (AM and presented abundant hyphae and coils in root cells, a characteristic of the anatomical Paris-type. Dark septate fungal endophytes were also observed. Values of total AM colonization were high, with similar partial AM% values for each root class. Seasonal differences were found for total and partial colonization, with higher values in spring compared to autumn. Regarding the percentage of fungal structures between root classes, values were similar for vesicles and arbuscules, but higher coil percentages were observed in GSR compared to LFR. The percentages of vesicles increased in autumn, whereas the arbuscule percentages increased in spring, coinciding with the plant growth peak. Results show that both root classes of A. araucana in Andean-Patagonian forests are associated with AM fungi, which may have ecological relevance in terms of the importance of this symbiosis, in response to soil nutrient-deficiencies, especially high P-retention.La conífera Araucaria araucana (Molina K.

    This paper reports the results obtained when a sludge age based control is incorporated in the biological process of a wastewater treatment plant (WWTP). Greater stability of the biological process is achieved when this control is implemented in WWTP of Molina de Segura. In particular biodiversity has increased and it has been possible to reduce and stabilize the secondary sludge production. An improvement of the sludge decantation and a reduction of the specific volumetric load of secondary clarifiers have also been observed. finally, costs have been reduced dur to the decrease of cationic polyelectrolyte consumption.

    The knowledge of the biological properties of fruits and leaves of murta (Ugni molinae Turcz.) has been owned by native Chilean culture. The present study investigated the phenolic content, the antioxidant, antimicrobial and anti-tyrosinase activities of different murta fruit and leaves extracts to approach their uses on future food, pharmaceutical and cosmetic applications. Extractions of murta fruit and leaves were carried out under water, ethanol and ethanol 50%. Phenolic content of these extracts was measured through Folin Ciocalteu test and the antioxidant power by four different antioxidant systems (ORAC, FRAP, DPPH and TEAC assays) owing to elucidate the main mechanism of antioxidant. Some flavonoids, such as rutin, isoquercitrin and quercitrin hydrate were identified and quantified through HPLC analysis. Antimicrobial activity was determined measuring minimum inhibition concentration (MIC) and minimum bactericidal concentration (MBC) values against Escherichia coli and Listeria monocytogenes, and the effect of these extracts on L. monocytogenes was confirmed by flow cytometry. Highest contents of polyphenol compounds were obtained in hydroalcoholic extracts (28±1mggallicacid/g dry fruit, and 128±6mggallicacid/g dry leaves). The same trend was found for the values of biological properties: hydroalcoholic extracts showed the strongest activities. Leaves presented higher antioxidant, antimicrobial and anti-tyrosinase properties than murta fruit. Highest antioxidant activity values according to ORAC, FRAP, TEAC and DPPH were 80±8mgTrolox/g, 70±2mgTrolox/g, 87±8mgTrolox/g and 110±12mgTrolox/g, respectively, for murta fruit samples, and 280±10mgTrolox/g, 192±4mgTrolox/g, 286±13mgTrolox/g and 361±13mgTrolox/g, respectively, for murta leaves. These activities were confirmed by HPLC analysis that revealed highest presence of analyzed compounds on leaves hydroalcoholic extract. Regarding to antimicrobial analysis, hydroalcoholic leaves extract presented the

    Full Text Available The outstanding outcrops of Upper Buntsandstein sediments (Middle Triassic in Molina de Aragón (Guadalajara area, allow a detailed study of their characteristics and their associations which are described here. The fluvial architecture of the section indicates four main depositional episodes. The two lowest episodes were laid down by a fluvial system characterized by frequent channel shifting, low sinuosity and wide shallow channels. The drainage basin was controlled by highly seasonal discharge. The middle episode evolved into a more distal systems, with smaller higher sinuosity channels and fine overbank deposits. The uppermost episode is related to an increase of slope in the basin. That increase is probably related to tectonic movements recorded in this area. An attempt has been made to correlate the above events to the global sea level fluctuations (Haq et al., 1987. So, the low stage that have been stated occurred during Early Anisian can be tentatively correlated with the uppermost episode in Areniscas del río Arandilla.Los excelentes afloramientos de la parte superior del Buntsandstein (Triásico medio en Molina de Aragón (Guadalajara, han permitido llevar a cabo un análisis sedimentológico detallado de las facies fluviales y de su arquitectura. Se han distinguido doce diferentes facies cuyas características y asociaciones se describen en este trabajo. La evolución fluvial indica la existencia de cuatro episodios deposicionales. Los dos episodios inferiores son característicos de un sistema fluvial con canales de baja sinuosidad, inestables, de gran amplitud y poca profundidad. El drenaje de la cuenca estaba controlado por importantes descargas estacionales. El episodio intermedio es el resultado de la evolución del sistema hacia facies más distales. En esta etapa los canales son de menor tamaño, la sinuosidad es mayor y existe un mayor porcentaje de depósitos de granulometría fina relacionados con la llanura de inundaci

    Full Text Available Murta (Ugni molinae Turcz. and common chaura (Gaultheria phillyreifolia (Pers. Sleumer are native species of Chile. Plants of both species have shown over-branching like witches' broom. The causal agents of these symptoms in many plants are phytoplasma. To verify the presence of these microorganisms, DAPI (4',6-diamidino-2-phenylindole staining analysis and polymerase chain reaction (PCR were performed in symptomatic and asymptomatic plants. Positive PCR samples were sequenced to identify the pathogens involved. In individuals of both species with witches’ broom symptoms, DAPI staining showed fluorescent bodies in the phloem tissues, but not in asymptomatic plants. Verification by nested-PCR, phytoplasmatic DNA was amplified from diseased murta and chaura, but not in apparently healthy plants. Sequencing of amplified products allowed locating phytoplasma within the ash yellows group (16SrVII and related to Candidatus phytoplasma fraxini. This is the first report of phytoplasma in Chilean native species. Considering the diversity of plant species infected by the ash yellows group suggests that G. phillyreifolia and U. molinae could be a phytoplasma reservoir for other economically important agricultural crops.La murta (Ugni molinae Turcz. y la chaura común (Gaultheria phillyreifolia (Pers. Sleumer son especies nativas de Chile. En plantas de ambas especies se ha observado una sobre-ramificación de tipo "escoba de bruja". En muchas plantas los agentes causales de esta sintomatología son fitoplasmas. Para verificar la presencia de estos microorganismos se analizaron plantas con y sin síntomas mediante tinciones DAPI (4’,6-diamidino-2-fenilindol y reacción en cadena de la polimerasa (PCR. Muestras positivas en la PCR fueron secuenciadas para identificar al fitopatógeno implicado. En individuos de ambas especies con síntomas de escoba de bruja, la tinción DAPI permitió observar cuerpos fluorescentes en los tejidos del floema, situaci

    Full Text Available The maize weevil (Sitophilus zeamais Motschulsky is one of most important pest of stored seeds worldwide, but its current control method is based on the use of synthetic insecticides, usually leading to undesirable problems such as insecticide residues on treated food, human intoxications, and insect resistance development. Therefore the search of friendly alternative methods is required. The aim of this study was to assess, under laboratory conditions, the insecticidal properties of Peumus boldus Molina, Laurelia sempervirens (Ruiz & Pav. Tul., and Laureliopsis philippiana (Looser Schodde essential oils against S. zeamais. The phytochemical analysis of the three essential oils showed 1,8-cineole, safrole and methyleugenol as the common components; all of them documented with insecticidal activity from essential oils from other plant species. The highest toxicity (100% mortality of these three oils acting as a contact insecticide was observed at 24 h exposure at 4% concentration. The estimated LC50 values for P. boldus, L. sempervirens, and L. philippiana were 0.37, 1.02, and 0.28 μL g-1, respectively. Peumus boldus exhibited the highest fumigant activity with 100% adult mortality at 30 μL oil L-1 air. At ≥ 0.5% (v/w concentration, all essential oils showed repellent activity. These three essential oils showed a promissory insecticidal activity against the maize weevil.

    Full Text Available This article presents the steps followed to obtain a three-dimensional model of one of the most recognized historical inventions of Agustín de Betancourt y Molina from the scant documentation found about it. Specifically, this was a machine for cutting cane and other aquatic plants in navigable waterways, presented in London in 1795. The study is based on computer-aided design (CAD techniques using Autodesk Inventor Professional, from the information provided by the only two sheets that exist from the machine, one with specifications in English and the other in French, both very similar. In order to obtain a functional result on which to carry out further studies, it has been necessary to make some geometrical hypotheses on the models, aimed to find the correct dimension of each element. In addition, it has also been necessary to define the relationship of each element with those that set up its environment, defining movement restrictions, so that the final model, behaves as real as possible.

    Full Text Available El interés por medir la producción científica ha originado un creciente número de índices. En este comentario examino críticamente los índices I e Is propuestos por Molina-Montenegro & Gianoli (2010; en este número, y los criterios empleados por estos autores para incorporar o excluir a científicos de su base de datos de investigadores chilenos en ecología. Además analizo la relación estadística entre los índices de producción científica I, Is y h de Hirsch, y las variables que los componen. Para ello empleo análisis de correlación y de regresión lineal. Los resultados muestran que luego de la corrección por el número de coautores y de autocitas que incorpora el índice I, este está principalmente asociado al log10 del número de alocitas, y mantiene una alta correlación con el índice h. Esto sugiere que el número de coautores y de autocitas no son predictores importantes de las diferencias entre ambos índices. En cambio, el índice Is es el único que disminuye con la edad científica, lo que se considera un efecto indeseable, y resultante de corregir mediante la división del valor del índice I por la edad científica. Al examinar los residuos de la regresión entre el log10 del número de alocitas y la edad científica se distingue nítidamente a quiénes habría que promover, contratar o premiar, lo que constituye una manera más simple y directa de evaluar comparativamente la producción de un investigador.The interest in measuring the scientific output has led to an increasing number of indices being proposed.

Os resultados obtidos evidenciaram que 45% das amostras analisadas se situavam fora dos padrões estabelecidos pela Organização Mundial da Saúde (OMS. Não foram observadas diferenças significativas na análise quantitativa da contaminação fúngica entre amostras comercializadas em farmácias de manipulação e mercados, tanto para o boldo-do-Chile como para a sene. Os fungos identificados nestas amostras foram: Aspergillus, Penicillium, Phoma, Cladosporium, Trichoderma, Rhizopus, Mucor, Aureobasidium pullulans, Mycelia sterilia, Acremonium e Monilia sitophila. Estes resultados demonstraram o baixo nível de qualidade desses fitoterápicos, pois, além do elevado número de amostras contaminadas, foram identificados fungos de gêneros produtores de micotoxinas, como o Aspergillus e o Penicillium.

Les légumes traditionnels africains sont considérés comme potentiellement utiles pour contribuer à la sécurité alimentaire et à la génération de revenu au niveau des communautés locales. Cependant, Egusi (Citrullus lanatus subsp. mucosospermus, Cucumeropsis mannii et Lagenaria siceraria cv. ' Aklamkpa ' a rarement fait l'objet de recherche et de promotion alors que sa culture persiste dans les systèmes de production de plusieurs pays de l'Afrique de l'Ouest. Cette étude met l'accent sur le rôle social des cultures de Egusi et leur importance dans le système de production des groupes sociolinguistiques au Bénin. En 2005, une investigation des systèmes de production et de culture de cinq régions socioculturelles prédominantes indique que la culture de Egusi est classée parmi les dix premières spéculations, selon la perception des ménages interrogés. Le rang attribué aux cultures de Egusi est relatif au genre mais pas à l'âge. Les agriculteurs allouent en moyenne 0,74 ha pour la production de Egusi, avec une différence significative d'une région sociolinguistique à une autre. Dans la communauté Mahi-Fon du centre Bénin, par exemple, nous avons observé des champs de production de Egusi allant jusqu'à 5 ha. L'espèce la plus cultivée est C. lanatus subsp. mucosospermus. Cependant, dans la communauté Adja du sud Bénin, la préférence des agriculteurs est pour L. siceraria cv. ' Aklamkpa '. Egusi se cultive au champ et en jardin de case, soit en association ou en monoculture. C. mannii est généralement cultivée en association et joue un rôle social très important dans les communautés Nagot-Yoruba.

En virtud de que la densidad de plantación es un factor determinante en el grado de competencia entre las plantas y de que el rendimiento por planta disminuye a medida que la densidad por unidad de superficie se incrementa, el objetivo de este estudio fue evaluar el efecto de tres densidades de plantación, en hileras a 2.0 m de separación con plantas espaciadas a 1.25, 1.55 y 2.00 m, sobre la producción y calidad de sandía sin semilla híbrido ‘Tri-X 313’, injertada sobre bule (Lagenaria siceraria (Molina Standl. híbrido ‘Emphasis’. El experimento se desarrolló utilizando un diseño en bloques completos al azar, con cuatro repeticiones. Las densidades de plantación evaluadas no influyeron sobre la producción de sandía sin semilla, híbrido ‘Tri-X 313’, injertada sobre L. siceraria; Sin embargo, las plantas injertadas mostraron una disminución del rendimiento por superficie con respecto de aquellas sin injertar, que varió del 10 al 24%, por lo que su uso está restingido a suelos con problemas de estrés causado principalmente por enfermedades. El peso promedio del fruto se incrementó en un 10% con el espaciamiento a 2.00 m. Asimismo, el número de frutos por planta disminuyó significativamente a medida que la densidad se incrementó. Los resultados en sandía injertada no fueron positivos por unidad de superficie; sin embargo, se obtuvo mayor producción por planta a menor densidad de plantación (mayor espaciamiento. Dado el incremento en los costos de producción al utilizar plantas injertadas, existe ventaja en el uso de menor densidad de plantación (mayor espaciamiento, pudiendose usar hasta un 50% menos densidad de plantación que en sandía sin injertar, sin afectar significativamente la producción y la

Nevertheless, few studies aimed at the improvement of these plants (related notably to taxonomy, genetic resources collecting missions, genetic characterisation, agronomic evaluation, and selection have been carried out. In order to set up a list of reliable traits that should be examined easily during and after collecting missions, we carry out in the present study, for three species (Citrullus sp., Cucumeropsis mannii Naudin and Lagenaria siceraria (Molina Standl a botanic description and an analysis of eleven agronomic traits: 100-seeds weight, germination rate, seedlings emergence time, matured fruit weight, matured fruit decomposition time, mean number of seeds per fruit, seeds shape, fruit diameter, fruit interior cavity diameter, flowering time, and fruiting time. Statistical analyses using nine of these traits showed that the three species can be completely distinguished with six traits whereas the three other traits allowed partial distinction. Low yields have been observed for the three species: 11.41 kg/ha of decorticated seeds for C. mannii, 18.51 kg/ha for Citrullus sp. and 75.14 kg/ha for L. siceraria. From the observed yield components, the possibilities to improve the production of these cucurbits are discussed.

    Full Text Available In the text of Tirso's Trilogía de los Pizarro elements are to be found which allow to affirm that the playwright availed himself of an occasional commission to make an instrument of political criticism aiming at false advisers and validos. Tirso fought against the novelties in the government and policy of the Inidies and stood for the abolition of the humanitarian measures of the Leyes Nuevas and the strengthening of the encomenderos' power. Thus the Trilogy presents itself as a telling instance of the mental shift between Renaissance erasmism and the crisis of the Counter-Reformation.

    En la Trilogía de los Pizarro hay elementos que permiten afirmar que el dramaturgo usó un encargo ocasional para hacer un instrumento de crítica de la política de su tiempo, poniendo en evidencia la figura de los validos y de los malos consejeros. Contra las novedades introducidas en el gobierno y en la política indiana Tirso proponía la abolición de las medidas humanitarias incluidas en las Leyes Nuevas y el fortalecimiento de la autoridad de los encomenderos. La Trilogía se presenta por lo tanto como un ejemplo del cambio cultural entre el erasmismo del Renacimiento y la crisis de la Contrarreforma.

    Full Text Available The objective of this study is to provide information about a harbour-fouling community dominated by Metridium senile in southern Patagonia. Several steel tubes from the wharf of Puerto San Julián were extracted to perform repair tasks, allowing the attached benthic community to be studied. Sampling was conducted at three levels: lower intertidal, 3-4 m depth and 6-7 m depth. In the lower intertidal, M. senile had a relative abundance of 43%, the most abundant accompanying species being Perumytilus purpuratus, Mytilus edulis platensis and Aulacomya atra atra. At subtidal level, the anemone showed relative abundances of 64% and 65%, and was accompanied by Monocorophium insidiosum at 3-4 m depth and by polychaetes of families Sabellidae and Syllidae at 6-7 m at depth. In the lower intertidal, epibiosis was more frequent on P. purpuratus, A. atra atra and M. edulis platensis, while in the subtidal, the richness of substrate-organisms increased significantly and the anemone was fixed to A. atra atra, M. edulis platensis, Paramolgula gregaria, Crepipatella dilatata, Austromegabalanus psittacus, Hiatella arctica, Polyzoa opuntia, Pyura sp. and Sabellidae tubes. The ability of M. senile to settle on many different organisms, along with other strategies, makes it a colonizer able to displace other species that could compete with it for substratum. Given the cosmopolitan nature of M. senile, the fact that this species has not been previously reported in the coastal zone of the region, and the results of our study, we discuss the possibility that this sea anemone is an invasive alien species in southern Patagonia, or at least a cryptogenic species.

    Full Text Available Las hembras del género Cáncer presentan una espermateca cuya conexión con el ovario puede ser dorsal o ventral, dependiendo de la especie. La espermateca es una estructura especializada para la recepción de los espermatóforos los cuales son colocados por el macho durante la cópula. El objetivo de este estudio es la descripción y medición de las estructuras reproductivas de ambos sexos en la jaiba peluda Cáncer setosus. Las hembras presentan un par de ovarios de conformación tipo H, siendo los lóbulos anteriores 2,4 veces más largos que los lóbulos posteriores. La espermateca es de paredes no extensibles y presentó una conexión de tipo ventral con el oviducto, lo que indica una fecundación interna para esta especie. El 64% de las hembras estudiadas presentó un par de tapones espermáticos: En los machos el primer par de pleópodos es tubular con su extremos distal aguzado y/o abierto formando un doblez. El segundo par de pleópodos termina en una estructura en forma de embudo con 12 prolongaciones laterales. Los testículos pares tienen un color blanquecino, y convergen en un vaso deferente, en el cual se puede distinguir tres zonas: una proximal, media y posterior. Cada uno de estos tiene un rol en la elaboración de los espermatóforos y la producción de líquido seminal.Females of the genus Cancer have a spermathecae whose connection with the ovary can be dorsal or ventral, depending on the species. The spermathecae is a structure specialized in receiving the spermatophores released by the male during mating. This study aims to describe and measure the reproductive structures of both sexes in the crab C setosus. Females have a pair of ovaries in an H-type conformation; the anterior lobes are 2.4 times longer than the posterior lobes. The spermathecae has walls that are not extensible and a ventral-type connection with the oviduct, which indicates internal fertilization for this species. Sixty-four percent (64% of the studied females presented a couple of spermatic blockages. In males, the first pair of pleopods is tubular, with the distal tips pointed and/or open, forming a fold. The second pair of pleopods ends in a funnel structure with 12 side extensions. The two testes are whitish in color and converge in a vas deference (VD that has three zones: proximal, middle, and posterior. Each of these plays a role in the elaboration of the spermatophores and seminal fluid production.

    Full Text Available Hasta fines del siglo pasado no existían registros de la presencia de Choromytilus chorus al norte de los 23°S, pese a antecedentes que señalaban su existencia en épocas pasadas. Ciertos cambios relacionados con las masas de agua costeras de esta zona, habrían generado la ausencia o escasez que presentaba el entorno costero actual. Sin embargo, hace una década atrás, su presencia en el norte de Chile, comienza a tener connotación pesquera. En el presente trabajo se confirma su reestablecimiento en las regiones de Antofagasta y Tarapacá, mediante prospecciones realizadas en seis lugares donde se registró su presencia, así como mediante la captación de semilla en colectores suspendidos. Se indica interacción con Aulacomya ater, a la cual ha desplazado a estratos más profundos, mientras que su reestablecimiento, iniciado en las regiones de Atacama y Antofagasta, y que se amplió posteriormente a la región de Tarapacá; permite postular la hipótesis que la dinámica de estos bancos, respondería a una estructura de metapoblación, dado el sistema de corrientes y vientos que predominan en la zona norte, permitiendo la advección larval de poblaciones existentes en la región de Coquimbo.Despite indications of its presence in past ages, until the end of the last century, no records showed Choromytilus chorus north of 23°S. Certain changes related to coastal water masses in the zone could be responsible for the present lack or scarcity of this species in the coastal area. However, a decade ago, this species appeared in northern Chile in the context of fisheries. This study confirms the re-establishment of C. chorus in the Antofagasta and Tarapaca regions through surveys at six sites where the species had been registered and spat collection using suspended collectors. This species has interacted with Aulacomya ater, displacing it towards deeper habitats. The re-establishment of C. chorus began in the Atacama and Antofagasta regions and later extended to the Tarapaca region. Thus, we hypothesize that the dynamics of these shoals correspond to a metapopulation structure that has allowed larval advection, given the current system and predominant winds in the northern zone, from populations existing in the Coquimbo region.

    Full Text Available Few avian studies on optical illusions are directly comparable to those with humans. Grey parrots that have some referential use of English speech, however, allow for such comparative studies, as these birds can be tested just as are humans, by asking them to describe exactly what they have seen. Here I review two studies, one on the Müller-Lyer illusion (Pepperberg, Vicinay, & Cavanagh, 2008, one on amodal and modal perception (Pepperberg & Nakayama, 2016, that demonstrate similarities between human and Grey parrot perceptual abilities.

    Full Text Available El año 2004, el Instituto del Patrimonio Histórico Español (IPHE en colaboración con el Ayuntamiento de Embid se pusieron de acuerdo para abordar la urgente restauración del castillo de Embid. Su estado de conservación era tal que amenazaba una ruina mucho mayor de la que presentaba después de que en los años 90 se viniera abajo la torre noreste. La torre del homenaje estaba a punto de desaparecer completamente. El proyecto y los trabajos de restauración le fueron encargados al arquitecto Pedro Ponce de León por el Ministerio de Cultura. El presente estudio es fruto del encargo para dicho proyecto. El 2006 terminaron los trabajos de restauración y con ellos la recuperación de un conjunto que estuvo a punto de perderse definitivamente. Sus restos preservados seguramente sirvan para que en el futuro se arroje más luz sobre una historia aún incompleta.In 2004, the Spanish Institute of Historical Patrimony in collaboration with the town council of Embid, agreed to address the urgent need of restoration of the castle of Embid. Its condition was such that was it was threatened by ruin, much greater than the one it endured after the northeast tower came down in the 90’s. The tower of the homage was about to disappear entirely. The Ministry of Culture commissioned the project and the restoration to the architect Pedro Ponce de Leon. This article is the result of the commission for the project. In 2006 the restoration ended and with it the recovery of the whole set was about to disappear. In the future its preserved remains would probably provide more insight to an incomplete episode.

    Using histochemical, histological and immunocytochemical methods, organisation of the autonomic nerve structures in small intestine of chinchilla was investigated. Myenteric plexus was localised between circular and longitudinal layers of the smooth muscles. Forming network nodes, the small autonomic, cholinergic ganglia were linked with the bundles of nerve fibres. Adrenergic structures were visible as specific varicose, rosary-like fibres forming bundles of parallel fibres connecting network nodes. Structures of the submucosal plexus formed a finer network than those of the myenteric plexus. Moreover, in 'whole-mount' specimens, fibres forming thick perivascular plexuses were also observed. Immunocytochemical studies confirmed the cholinergic and adrenergic character of the investigated structures. VAChT-positive neurones were found only in myenteric plexus, and numerous VAChT-positive and DBH-positive fibres were found in both plexuses. © 2013 Blackwell Verlag GmbH.

    Rotavirus is the leading cause of severe diarrhea disease in newborns and young children worldwide with approximately 300,000 pre-adolescent deaths each year. Quillaja saponins are a natural aqueous extract obtained from the Chilean soapbark tree. The extract is approved for use in humans by the FDA for use in beverages as a food addictive. We have demonstrated that Quillaja extracts have strong antiviral activities in vitro against six different viruses. In this study, we evaluated the in vivo antiviral activity of these extracts against rhesus rotavirus (RRV) using a mouse model. We established that at a dosage of 0.015 mg/mouse of saponin extract, RRV induced diarrhea can be significantly reduced from 79% to 11% when mice are exposed to 500 plaque-forming-units (PFU) for each of five consecutive days. Additionally, while a reduction of RRV induced diarrhea depended both on the concentration of virus introduced and on the amount of Quillaja extract given to each mouse, the severity and interval of diarrhea under a variety of conditions tested, in all the treated mice were greatly reduced when compared to those that did not receive the Quillaja extracts. Mechanistically, there is strong evidence that the Quillaja extracts are able to “block” rotavirus infection by inhibiting virus-host attachment through disruption of cellular membrane proteins and/or virus receptors. We believe that Quillaja extracts have promise as antivirals to reduce rotavirus infection and the severity of the disease in humans. PMID:21549151

    2004-06-01

    Full Text Available Ensis macha is a razor clam distributed throughout the coasts of southern Argentina and Chile. Even though it represents a valuable fishery resource, the exploitation of its Atlantic populations has begun only in recent years. This study provides the first estimates of growth rate, an interpretation of the reproductive cycle on the coast of the northern Argentine Patagonia and an analysis of the species morphometry. Growth was estimated by direct observation of growth rings on the valves by two observers. The reproductive cycle was interpreted by the analysis of temporal change of oocyte size frequency distributions. Parameter estimations for the von Bertalanffy equations respectively obtained by observers 1 and 2 were 154 and 153.7 mm for L?, 0.25 and 0.20 yr-1 for k, and -0.08 and -0.72 yr for t0. Two spawning peaks were detected: September-November 1999 and May-June 2000. However, mature females were found all year round. An abrupt change in the relationship between shell length and height was detected at 11.2 mm length.

    In the iscom, multiple copies of antigen are attached by hydrophobic interaction to a matrix which is built up by Quillaja triterpenoid saponins and lipids. Thus, the iscom presents antigen in multimeric form in a small particle with a built-in adjuvant resulting in a highly immunogenic antigen formulation. We have designed a chloroform-methanol-water extraction procedure to isolate the triterpenoid saponins and lipids incorporated into iscom-matrix and iscoms. The triterpenoids in the triterpenoid phase were quantitated using orcinol sulfuric acid detecting their carbohydrate chains and by HPLC. The cholesterol and phosphatidylcholine in the lipid phase were quantitated by HPLC and a commercial colorimetric method for the cholesterol. The quantitative methods showed an almost total separation and recovery of triterpenoids and lipids in their respective phases, while protein was detected in all phases after extraction. The protein content was determined by the method of Lowry and by amino acid analysis. Amino acid analysis was shown to be the reliable method of the two to quantitate proteins in iscoms. In conclusion, simple, reproducible and efficient procedures have been designed to isolate and quantitate the triterpenoids and lipids added for preparation of iscom-matrix and iscoms. The procedures described should also be useful to adequately define constituents in prospective vaccines.

    Full Text Available In March 1968, Portuguese censors stopped the broadcast on public television —which was the only television network at the time— of Tirso de Molina’s comedy Las quinas de Portugal. This play stages the most important creation myth for the Portuguese nation: on the eve of the battle of Ourique, a crucified Christ appeared and offered Count Afonso Henriques his five holy wounds as a symbol for the Portuguese coat of arms. In this article, I intend to understand the ethical and political reasoning of the censors who read this play, written by one of the most important playwrights of the Spanish Golden Age

    Effects of high hydrostatic pressure (HHP) on rheological and thermophysical properties of murtilla berries were evaluated after pressure treatments for 5 min between 100 and 500 MPa. Differential scanning calorimetry was employed to measure specific heat capacity. HHP caused a significant decrease in specific heat and density, while thermal diffusivity did not changed significantly. Thermal conductivity showed a slight increase upon HHP treatment. Apparent viscosity increased significantly above 200 MPa HHP treatment. Apparent viscosity of treated samples between 200 and 400 MPa did not differ significantly and the increase was significant at 500 MPa. Herschel-Bulkley, Bingham and Ostwald de Waele models were used to describe the rheological behaviour of murtilla purée, and Ostwald de Waele model gave the best fit for the experimental data.

    Full Text Available We analyzed the distribution of marine otter Lontra felinaon the Peruvian coast, from Punta Aguja (05°47'S to the boundary with Chile (18°21'S. We performed a comprehensive analysis of the literature on L. felinato elucidate a northern boundary of its geographic distribution, concluding that there is no solid evidence of a possible northern limit at 6°S. For the same reasons, the affirmation of a "historic distribution" to the Lobos de Tierra island was discarded. It is also presented information of 272 otters from 130 locations between the years 2000 and 2010. The distribution of these records no has spatial autocorrelation, suggesting a homogeneous distribution. Considering the morphostructure and geomorphology of the Peruvian coast we can see similarities with the division into three zones: north, central and south, the last two add all records of otters, which could provide habitat characteristics that, allow a continuous distribution of L. felina. Finally there is an increase in the number of otters in the Peruvian coast to compare the current values with those of 40 years ago, but we show the lack of traceability of the latest information. We suggest undertaking research linking abundances and densities of otters with the characterization and distribution of their habitats, and behavioral studies that reveal the processes or intrinsic characteristics of the species to move into its geographic range.

    Avian chlamydiosis is caused by Chlamydiophila psittaci with the highest infection rate in parrots (Psittacidae) and pigeons (Columbiformes). A two-year-old Congo African grey parrot was examined since the bird had shown clinical signs of anorexia, depression, diarrhea, and mild dyspnea and based on biochemical and hemathological analysis the bird was diagnosed as having anemia, leukocytosis, heterophilia, lymphopenia and monocytosis. With regards to clinical and paraclinical findings, the case was diagnosed to be carrying Chlamydiophila spp. In addition, choanal cleft and cloaca swabs were positive for Chlamydiophila spp. in a diagnostic polymerase chain reaction (PCR) (600 bp amplicon). Polymerase chain reaction products were typed by ompA gene-based PCR, using CTU/CTL primers (1050 bp amplicon). The PCR product sequence was compared with the sequences obtained from GenBank. The phylogenetic tree has revealed 100% identity with genotype B obtained from previous studies. The bird was hospitalized and treated with doxycycline regimen for 45 days, with a weekly sampling process to trace the presence of C. psittaci DNA in faecal and choanal swabs, this process continued to the point where the specimens turned negative after two weeks. Laboratory and radiology results were within normal limits after the treatment. Genotype B is predominantly isolated from Columbidae and there have not been any reports regarding the clinically affected African gray parrot with this genotype. Subsequently, to the best of our knowledge, this is the first report of chlamydiosis by genotype B on Congo African grey parrot. PMID:28224015

    The objective of this study was to examine the normal respiratory tract of grey parrots and amazons by using two different methods. The lower respiratory tract of five amazons and four grey parrots, all healthy, were investigated applying computerised tomography (CT). Volumes and densities of the body, the body cavities, the normal lungs, and the airsacs in the living animals were defined as reference values of healthy birds to give a basis for future CT-diagnosis of respiratory diseases and their precise locations in parrots. In a parallel study, the lung and air sac volumes of six amazons and two grey parrots were measured using silicone rubber casts produced after the method described byH.-R. Duncker. Values for identical respiratory structures gained by these different methods were compared

    Full Text Available La fragmentación que ha sufrido el bosque nativo de Chile debido a la fuerte presión antrópica ha causado, además de la grave pérdida de habitat, la modificación del microclima de los parches de bosque remanente que alguna vez constituyeron un bosque continuo de especies nativas. Estos cambios generarían respuestas morfológicas, químicas y fisiológicas en plantas capaces de adaptarse a las nuevas condiciones. Este estudio tiene como objetivo identificar respuestas a nivel de las hojas ante el aumento de radiación solar y disminución de agua en el suelo que ocurre al interior de los fragmentos. Para esto utilizamos a Aristotelia chilensis, especie que crece tanto en fragmentos como en bosque continuo, y comparamos parámetros relacionados a su morfología foliar en bosque y fragmentos y medimos su repercusión en la capacidad fotosintética de A. chilensis. En términos morfológicos, se observó una disminución del área foliar y del área foliar específica en los fragmentos, siendo 1,2 veces menor que en el bosque continuo. En los fragmentos, el grosor de la epidermis y del parénquima esponjoso son más de 1,3 veces mas gruesos que en el bosque continuo. El grosor del parénquima en empalizada, en cambio, no se vio modificado. La cantidad de nitrógeno en las hojas es 1,2 veces mayor en el bosque continuo que en los fragmentos, mientras que el contenido de carbono no varía. La conductancia estomática en el bosque continuo fue 1,5 veces mayor que en los fragmentos. Aristotelia chilensis responde morfológica y fisiológicamente ante los cambios abióticos generados por la fragmentación de los bosques, lo que le permite sobrevivir tanto en ambientes de baja luminosidad como el bosque continuo y en ambientes de alta luminosidad y bajo contenido hídrico como los fragmentos de bosque, manteniendo tasas fotosintéticas semejantes en ambos ambientesFragmentation of the Maulino forest implies significant habitat loss, as well as the modification of the microclimatic conditions of the remaining forest patches. Fragments are drier, hotter and receive more light than the continuous forest. These changes might induce morphological, chemical and physiological responses on individuals inhabiting forest patches. This study aims to identify morpho and physiological changes in Aristotelia chilensis, an evergreen tree that grows both in forest fragments and continuous forest. Leaves were 1.2 times smaller in forest fragments than in the continuous forest. Similar reduction was observed on specific leaf area (SLA. In forest fragments, the thickness of epidermis and of the spongy mesophyll was more than 1.3 times larger than that on the continuous forest, whereas the thickness of the palisade mesophyll did not differ. The amount of foliar nitrogen was 1.2 times larger in the continuous forest than in fragments, whereas the carbon content did not differ. Stomatal conductance in the continuous forest was 1.5 fold higher than that in forest fragments. Changes depicted by A. chilensis allows it to survive in environments of low luminosity as the continuous forest, and in environments of low water content as the forest fragments, maintaining similar photosynthetic rates in both environments

Se discuten los resultados en términos taxonómicos, biogeográficos y paleoecológicos sugiriendo que la presencia de este taxón fuera de su rango actual de distribución se debió a las condiciones ambientales compartidas entre la Puna y Patagonia austral durante la transición Pleistoceno-Holoceno. La extinción de V. vicugna se habría debido al impacto de los cambios climáticos ocurridos al inicio del Holoceno producto de su dieta pastadora y etología no migratoria y territorial, a lo que se habría sumado una caza por parte de depredadores humanos y no humanos.Palabras clave: género Vicugna, osteometría, Pleistoceno, Patagonia AbstractThis contribution presents the results of single and multi-variable osteometric analyses performed on a sample of short bones and phalanxes assigned to Vicugna sp. from Lago Sofía Cave 4 site (13500 – 11000 BP, Región de Magallanes, Chile. The elements analyzed show a similar size to the reference collections for Vicugna vicugna, and do not exceed the metrics for the pampean pleistocenic specimens of Vicugna gracilis. This confirms the morphological and ancient DNA data that indicated the presence of vicuña in southern Chilean Patagonia. The taxonomic, biogeographic and palaeoecologic discussion of these results, suggests that the presence of this species outside its current distribution range was due to shared environmental conditions between the Puna and Patagonia during the Pleistocene-Holocene transition. The extinction of this form is, most likely, due to the impact of climatic change during the begining of the Holocene over its pasturing diet and its territorial and non migratory habits. It is added to this, a hunting pressure by human and non-human predators.Keywords: Vicugna genus, osteometry, Pleistocene, Patagonia

    Successful cultivation of bottle gourd in arid and semi-arid areas of sub-Saharan Africa and globally requires the identification of drought tolerant parents for developing superior genotypes with increased drought resistance. The objective of this study was to determine the level of drought tolerance among genetically diverse South African bottle gourd landraces based on leaf gas exchange and photosynthetic efficiency and identify promising genotypes for breeding. The responses of 12 bottle gourd landraces grown in glasshouse under non-stressed (NS) and drought-stressed (DS) conditions were studied. A significant genotype x water regime interaction was observed for gs, T, A, A/C i , IWUE, WUE ins , F m ', F v '/F m ', Ф PSII , qP, qN, ETR, ETR/A and AES indicating variability in response among the studied bottle gourd landraces under NS and DS conditions. Principal component analysis identified three principal components (PC's) under drought stress condition contributing to 82.9% of total variation among leaf gas exchange and chlorophyll fluorescence parameters measured. PC1 explained 36% of total variation contributed by gs, T, F 0 ', F m ', F v '/F m ' and qN, while PC2 explained 28% of the variation and highly correlated with A, A/C i , IWUE, WUE ins ETR/A and AES. PC3 explained 14% of total variation contributed by Ф PSII , qP and ETR. Principal biplot analysis allowed the identification of drought tolerant genotypes such as BG-27, BG-48, BG-58, BG-79, BG-70 and BG-78 which were grouped based on high gs, A, F m 'F v '/F m ', qN, ETR/A and AES under DS condition. The study suggests that the identified physiological traits could be useful indicators in the selection of bottle gourd genotypes for increased drought tolerance.

    Full Text Available This study describes the intraspecific variation of 30 edible-seed Lagenaria siceraria germplasm accessions from the University of Abobo-Adjamé. These accessions were collected from three (Centre, East and South geographical zones of Côte d’Ivoire. Selection based on seed size by the farmers has resulted in subdividing the species into two cultivars: large-seeded and smallseeded. The morphological diversity study of the collection included 18 accessions and 24 traits. The multivariate analysis of variance (MANOVA showed a significant difference between the two groups of cultivars. Principal component analysis on 13 traits pointed out variations among individuals, mainly on the basis of flower, fruit, and seed size. Dendrogram with UPGMA method allowed clustering of the cultivars. The genetic structure analysis among accessions using allozyme markers showed the following values: 18.95% for the proportion of polymorphic loci (P, 1.21 for the number of alleles (A and 0.053 for observed heterozygosity (Ho. The level of the within accessions genetic diversity (HS = 0.188 was higher than the genetic variation among accessions (DST = 0.082. The estimates of F-statistics indicated a low level of genetic differentiation between accessions (FST = 0.298. Such a value suggested that L. siceraria maintains about 30% of its genetic variation among accessions. Nei genetic distances between the two cultivars were also low (0.002, indicating that cultivars were genetically similar enough to belong to the same genetic group.

    The effect of residual concentrations of organophosphate pesticide chlorpyrifos (Lorsban 4E) on the activity of the acetylcholinesterase enzyme and oxygen : nitrogen ratio in the mussel Aulacomya ater was analyzed. Toxicity tests show a sensitivity to the pesticide in the bivalve estimated at 16 μg L−1 (LC50−96 hours). Concentrations between 0.2 and 1.61 μg L−1 were able to inhibit significantly the AChE activity, and concentrations between 0.8 and 1.61 μg L−1 stimulate ammonia excretion and decrease oxygen : ammonia-N (O : N) ratio, with respect to the control group. A. ater proved to be a species sensitive to pesticide exposure and easy to handle in lab conditions. Thus, it is recommended as a bioindicator for use in programs of environmental alertness in the Eastern South Pacific coastal zone. PMID:22619673

The morphology of the starch granules (size and shape was studied with scanning electron microscopy (SEM, which revealed ellipsoid, oval, conical, pear-shaped and prismatic forms: ellipsoids and oval granules with lengths up to 54.30 µm in oca; with lengths up to 32.09 µm for olluco starch granules; and with predominantly truncated spherical or oval forms and smaller dimensions (up to 16.29 um for mashua starch granules. Amylose contents were similar among the samples: 27.60% (oca, 26.49% (olluco and 27.44% (mashua. Olluco starch had less swelling power, forming opaque, less firm gels. All three starch gels showed the same stability on refrigeration and presented high syneresis under freezing temperatures, with a variation of 40.28 to 74.42% for olluco starch. The starches cooked easily, with high peak viscosity. The low gelatinization temperatures and high stability during cooling make these starches suitable feedstock for use in formulations that require milder processing temperatures and dispense freezing storage.

    The aim of this work was to determine the protective effect of different dietary fibers on (i) the recovery and bioaccessibility indexes, and (ii) the stability of polyphenolic compounds (phenolic acids, flavonoids and anthocyanins) of maqui berry powder subjected to in vitro gastrointestinal digestion (GID). The extracts obtained in each phase (oral, gastric and intestinal) of GID were used to analyze the stability of polyphenolic compounds by HPLC, and the bioaccessibility of these compounds was also determined. At the end of the GID process, the mixture of maqui berry with the different fibers increased the bioaccessibility index of the phenolic and flavonoid compounds in all cases. The results obtained suggest that the anthocyanins and phenolic acids and flavonoid compounds present in maqui are stabilized through dietary fiber interactions, which might provide sufficient levels for absorption during gastrointestinal digestion. The gums sodium carboxymethyl cellulose, xanthan gum and guar gum provided the best protective effect.

    Full Text Available La extracción indiscriminada y alteraciones del medio natural, han puesto en peligro de extinción al único Palaemónido dulceacuícola de interés comercial, presente en aguas continentales chilenas. Aun cuando esta situación, ha despertado el interés en estudios que permitan su reproducción controlada en cautiverio, actualmente es escaso el conocimiento acerca de aspectos reproductivos básicos de esta especie. Dada su importancia, este trabajo describe y caracteriza el proceso completo de maduración gonadal en hembras de Cryphiops caementarius, en base a cambios en la morfología externa e interna del ovario. Hembras adultas extraídas del río Limarí, fueron disectadas y sus ovarios removidos y preparados para análisis histológicos. Tejido fibromuscular divide el tejido gonadal de cada lóbulo en sacos ováricos de forma semicónica (conos de maduración, al interior del los cuales se encuentran ovocitos en diferentes estados de desarrollo de acuerdo a observaciones microscópicas de tamano, morfología y tinción con H-E, las células reproductoras femeninas se clasificaron en seis tipos, ovogonias (Ov, ovocitos previtelogénicos tempranos (O1, ovocitos previtelogénicos tardíos (O2, ovocitos vitelogénicos tempranos (O3, ovocitos vitelogénicos tardíos (O4 y ovocitos Maduros (OM. El ciclo de madurez gonadal se dividió en cinco estados según la cantidad y tipo de ovocitos presentes. Los estados 0 y I, corresponden a desovado y previtelogénesis. Los estados II y III a vitelogénesis temprana y vitelogénesis intermedia, mientras el estado IV corresponde a madurez avanzada. La presencia de ovogonias y ovocitos previtelogénicos junto a ovocitos completamente maduros en el estado de madurez avanzada, refleja la capacidad de esta especie de realizar ciclos consecutivos de madurez en intervalos cortos de tiempo.Its indiscriminate extraction and alterations of its natural environment, has put in danger of extinction the only commercial freshwater Palemonid present in Chilean inland waters. Even though this situation has awakened interest in studies which allow its controlled reproduction in captivity, currently little is known regarding basic reproductive aspects of this species. Given its relevance, this work describes and characterizes the whole ovarian cycle of Cryphiops caementarius, based on changes in external and internal ovarian morphology. Adult C. caementarius females, obtained from Limarí River, were dissected and its ovaries removed and prepared for histological examinations. Fibromuscular tissue divides the ovarian tissue of each lobe into cone-shaped ovarian pouches (Maturation cones, each one containing various steps of oocytes according to the stages of ovarian development. Based on light microscopic observations of cells' sizes, morphology, and staining with H-E, the female germ cells could be classified into six different types, which include oogonia (Ov, early previtellogenic oocytes (O1, late previtellogenic oocytes (O2, early vitellogenic oocytes (O3, late vitellogenic oocytes (O4 and mature oocytes (OM. The ovarian cycle is divided into five stages based on the amount and types of oocytes present in each stage. Stage 0 and I are spawned and previtellogenesis stages. Stage II and III are early and intermediate vitellogenesis stages, while stage IV is maturity advanced stage. The presence of oogonia and previtellogenic oocytes among fully mature oocytes in stage IV reflect the capacity of the ovary of C. caementarius females to start a new full maturity cycle in a short time period.

    Full Text Available One of the factors thought to contribute to ontogenetic declines in plant growth rates is diminishing light interception efficiency, as a result of the difficulties of avoiding self-shading among a growing number of leaves, and by stems. The effects of plant size on self-shading and light interception have rarely been quantified, however. We used a three-dimensional digitising system to construct virtual models of the architecture of Araucaria araucana seedlings 71 to 358 mm tall, and modelled their light interception in the forest understorey using the program YPLANT. We also analyzed seedling allometry, to determine the combined effects of biomass distribution and self-shading on total light interception. Average light interception efficiencies calculated for A. araucana (29 % were the lowest reported for rainforest tree seedlings, reflecting the limitations imposed by short leaves, lack of petioles and an inability to develop planar foliage geometry on branches. Total light interception was related to seedling leaf area by an exponent of 0.735, reflecting increasing self-shading as seedlings grew bigger. However, because leaf area was related to seedling mass by an exponent of 1.24, light interception scaled nearly isometrically (0.91 power with seedling mass. This resulted from taller plants having proportionally thinner stems, and a smaller fraction of their biomass in roots. Thus, an ontogenetic increase in self-shading in A. araucana is largely offset by allocation changes which increase leaf area ratio as seedlings grow bigger. These mechanisms conserving the relationship of light interception with plant mass seem likely to be restricted to species with long-lived leaves, growing in humid situations protected from wind stress. In open habitats, where wind and drought stress likely make such allocation patterns less feasible, the role of self-shading in ontogenetic declines in relative growth rate may be more evidentLa caída en la eficiencia de intercepción de la luz es considerada como uno de los factores responsables del declive ontogenético en las tasas de crecimiento relativo de las plantas, debido a la dificultad de evitar el autosombramiento entre un creciente número de hojas. Sin embargo, rara vez se ha cuantificado el efecto de tamaño de las plantas sobre el autosombramiento y la eficiencia en intercepción de la luz. Utilizamos un sistema de digitalización para construir modelos virtuales tridimensionales de la arquitectura de plántulas 71-358 mm de alto de la conífera Araucaria araucana, y modelamos su intercepción de la luz en el sotobosque mediante el programa YPLANT. Analizamos además la alometría de las plántulas para determinar los efectos combinados de la distribución de biomasa y el autosombramiento sobre la intercepción total de luz a nivel de la planta entera. La eficiencia promedio de intercepción de la luz de A. araucana (29 % fue la más baja documentada para plántulas de especies de bosques húmedos, reflejando las limitaciones impuestas por hojas cortas, carencia de pecíolos, y la incapacidad de desarrollar follaje plagiotrópico. La intercepción total de luz por las plántulas fue proporcional al área foliar0,735, producto de un aumento en el autosombramiento en función del tamaño. Sin embargo, debido a la relación del área foliar con la potencia 1,24 de la masa de las plántulas, la intercepción de luz se acercó a la proporcionalidad directa (exponente 0,91 con la masa. Este patrón fue producto de la relativa delgadez de los tallos de las plántulas grandes, y su baja proporción de biomasa radicular. Por tanto, el declive ontogenético en la eficiencia de intercepción de la luz fue en gran medida compensada por cambios de asignación que aumentaron la superficie foliar de las plántulas grandes. Estos mecanismos que conservaron la relación de la ganancia potencial de carbono con la masa de las plántulas probablemente serán vistos solamente en especies con hojas muy longevas, en hábitats húmedos con poco viento. En ambientes abiertos, donde los estrés por sequía y viento podrían seleccionar en contra tales patrones de asignación, es probable que se evidencie más claramente el rol del autosombramiento en los declives ontogenéticos en la tasa de crecimiento relativo

    Full Text Available Se estudia el desarrollo larvario del camarón de río del norte de Chile, Cryphiops caementarius, desde el estado de zoea 1 hasta el primer juvenil, caracterizando y analizando criterios que verificaron la aplicación de indicadores de tipo morfológico y de comportamiento para la evaluación de la condición larvaria de la especie, en condiciones de cultivo. Las larvas, se mantuvieron en cultivo, en un tanque de 250 L con agua a 20 psu y temperatura de 25 ± 1°C, controlada con termostato y con un recambio del 100% diariamente. La alimentación consistió en microalgas (Nannochloris sp. e Isochrysis sp., rotíferos (Brachionus plicatilis, nauplios de Artemia franciscana y alimento formulado. Se utilizaron cinco indicadores de carácter morfológico y de comportamiento aplicados a las larvas de C. caementarius: llenado intestinal, estado de la glándula digestiva, desarrollo branquial, comportamiento natatorio y respuesta fototáctica. Estos indicadores, permitieron determinar el estado de condición y calidad de las larvas de C. caementarius, logrando un efectivo seguimiento y asociación de cada uno de ellos, con cada estado de desarrollo larvario, estandarizando características deseables en las larvas y evidenciando resultados verificables, que permitan establecer un adecuado plan de seguimiento del cultivo, optimizar los protocolos de manejo y de alimentación de las larvas. Además de cada indicador, fue posible desglosar una amplia gama de potenciales estudios a realizar, basados en las relaciones que la morfología y el comportamiento larvario mantienen con las capacidades fisiológicas de las larvas en desarrollo.The larval development of the Chilean northern river shrimp Cryphiops caementarius was studied, from the condition of zoea 1 up to the condition of juvenile stage, analyzing and characterizing diverse criteria that allowed checking the application of morphological and behavioral indicators for the evaluation of the larval quality of the species, under conditions of culture. The larvae, were cultured, in a tank of 250 L with water at 20 psu, at a constant temperature (25° ± 1°C, controlled with a thermostat and with 100% refill every day. The diet consisted of microalgae (Nannochloris sp. and Isochrysis sp., rotifers (Brachionus plicatilis, nauplii of Artemia franciscana and formulated food. Five indicators were used, considering morphologic and behavior aspects: intestinal fill, midgut gland condition, gill development, swimming behavior and phototactic response. The indicators selected in the present work, were feasible of being used for the determination of the condition and quality of the larvae of C. caementarius, being able to make an effective follow-up and association with every condition of larval development, standardize desirable characteristics in the larvae and demonstrate verifiable results, using a protocol for culture and food supply. Moreover, it was possible to identify an extensive range of potential studies, based on the relationships that the morphology and the larval behavior support with the physiological capacities of the larvae in development.

    Full Text Available Andean grains (i.e. quinoa, amaranth have been increasingly studied in recent times, mainly due to the increase in international consumption. However, Andean tubers other than potatoes have not been so widespread and are mainly studied for their starch, previously extracted. This work studied the morphology of native starch in four of these crops (oca, olluco, isaño and aracacha, during cooking and the evolution of their internal temperature in relation to sensory acceptability. Using scanning electron microscopy, it was determined that the size of crude starch granules was between 9 μm to 38.2 μm for oca, 4.48 to 24.9 μm for olluco, 4.45 to 22.9 μm for isaño, and 5.36 to 23.8 μm for arracacha. Sensorially, it was determined that the optimum cooking temperature for arracacha was 89.1°C, 90.9°C for oca, 91°C for isaño, and 91.4 °C for olluco. All samples had optimal cooking times shorter than potato, with the isaño having the best heat transfer.

    Full Text Available Crisis de la modernidad, emancipación y alienación cuestiona a través de cinco textos la creencia de una subjetividad constitutiva atrapada en la lógica de una mera libertad negativa propia de la modernidad ilustra- da, caracterizada por la irrupción de una economía capitalista, el Esta- do-nación y la apuesta por la ciencia experimental. Una modernidad en crisis que, como lo señala el prefacio, será su hilo conductor. En efecto, la promesa emancipadora y pacificadora de la modernidad está en filo y lo que se devela son procesos de alienación mediante sofisticados dis- positivos de subjetivación como los jurídicos y figuras como el estado de excepción, anclaje de la soberanía contemporánea. La felicidad sensual se nos presenta en el libro como una aspiración y escenario de emanci- pación con sutiles resonancias en la propuesta de un ser cual sea y en la de la comunidad que viene. En estas tensiones entre modernidad, eman- cipación y alienación, el lenguaje, sus tamices, movimientos, horizonte abierto, adquiere relevancia conceptual y metodológica en aras de un sentido nómada.

    Chemotherapy-resistant urothelial carcinoma has no uniformly curative therapy. Understanding how selective pressure from chemotherapy directs the evolution of urothelial carcinoma and shapes its clonal architecture is a central biological question with clinical implications. To address this question, we performed whole-exome sequencing and clonality analysis of 72 urothelial carcinoma samples, including 16 matched sets of primary and advanced tumors prospectively collected before and after chemotherapy. Our analysis provided several insights that are as follows: (1) chemotherapy-treated urothelial carcinoma is characterized by intrapatient mutational heterogeneity, and most mutations are not shared; (2) both branching evolution and metastatic spread are very early events in the natural history of urothelial carcinoma; (3) chemotherapy-treated urothelial carcinoma is enriched with clonal mutations involving L1 cell-adhesion molecule and integrin signaling pathways; and (4) APOBEC-induced mutagenesis is clonally enriched in chemotherapy-treated urothelial carcinoma and continues to shape the evolution of urothelial carcinoma throughout its lifetime.

    Full Text Available Objective – To provide an updated categorization of Library and Information Science (LIS publications and to identify trends in LIS research.Design – Bibliometric study.Setting – The Library and Information Science Abstracts (LISA database via the CSA Illumina interface.Subjects – 11,273 item records published from 2004-2005 and indexed in LISA.Methods – First, a search was set up to retrieve all records from 2004-2005, limited to peer review items (called “arbitrated works” by the authors (150 and excluding book reviews. Second, thematic descriptor terms used for the records were identified. Frequency counts for descriptor term occurrence were compiled using Microsoft Access and Pajek software programs. From the results of this search, the top terms were analyzed using the Kamada-Kawai algorithm in order to eliminate descriptor term co-occurrence frequencies under 30. A cluster analysis was used to depict thematic foci for the remaining records, providing a co-word network that visually identified topic areas of most frequent publication. Conclusions were drawn from these findings, and recommendations for further research were provided.Main Results – The authors identified 18 “thematic research core fields” (152 clustered around three large categories, “World Wide Web”, “Education”, and “Libraries”, plus 12 additional peripheral categories, and provided a schematic of field interrelationships.Conclusion – Domains of greatest focus for research “continue to be of practical and applied nature,” (153 but include increased emphasis on the World Wide Web and communications technologies, as well as on user studies. A table of the most frequently occurring areas of research along with their top three descriptor terms is provided (Table1, 152 (e.g., “World Wide Web” as the top area of research, with “online information retrieval” (268 occurrences, “searching” (132 occurrences, and “web sites” (115 occurrences.

    Full Text Available The text is an analysis of the novel Night in the Tavern by Álvares de Azevedo, approaching the characters´ torn experiences, which are the same lived by the hero Don Juan in El Burlador de Sevilla by Tirso de Molina. Beginning with the issue of the duplicity in the romanticism, we find in Tirso de Molina and Álvares de Azevedo the representation of rivalry present in the donjuanesque theme, the search for the hero identity with the rival and the seduction of the wife of the rival as something valuable. However, the damnation traces the destiny of the romantic hero.

  9. Histopathological survey of protozoa, helminths and acarids of imported and local psittacine and passerine birds in Japan.

    1992-12-01

    A total of 534 psittacine and passerine birds consisting of 241 imported and 293 local birds were examined histologically. As a result, the following parasites were found: Giardia (86 cases), Knemido-coptes (26 cases), coccidia (10 cases), Ascaridia (6 cases), Cryptosporidium (5 cases), Sarcocystis (5 cases), tapeworm (4 cases), microfilaria (2 cases), Hexamita (1 case), and Spiroptera (1 case). High incidences of giardiasis and knemido-coptic infestation were detected in the local birds, but rarely in the imported birds. Giardial trophozoites were observed mainly in the duodenum of budgerigars (Melopsittacus undulatus). Knemidocoptic mites burrowed into the epidermis producing proliferative dermatitis in 25 budgerigars and 1 African Grey Parrot (Psittacus erithacus erithacus). This ectoparasite often infested the skin around the cloaca. Coccidiosis was seen only in the small intestines of the finch (Poephila gouldiae gouldiae), African Grey Parrot, Rainbow lory (Trichoglossus haematodus), Indian Ring-necked parakeet (Psittacula krameri manillensis) and peach-faced lovebird (Agapornis roseicollis). Two parrots (Amazona aestiva aestiva and Psittacus erithacus erithacus) and two budgerigars had intestinal cryptosporidiosis. Conjunctivitis associated with cryptosporidial infection was seen in a lovebird. Sarcocystis cysts containing crescent-shaped bradyzoites were found not only in the thigh and breast but also in the heart and cloacal muscles. Other organisms such as Ascaridia, tapeworm, microfilaria, Hexamita, and Spiroptera were clinically less significant. However, infections such as Giardia and Cryptosporidim might have zoonotic implications.

    2016-02-04

    Maule Cohort (MAUCO), a Chilean cohort study, seeks to analyze the natural history of chronic diseases in the agricultural county of Molina (40,000 inhabitants) in the Maule Region, Chile. Molina´s population is of particular interest because in the last few decades it changed from being undernourished to suffering excess caloric intake, and it currently has the highest national rates of cardiovascular diseases, stomach cancer and gallbladder cancer. Between 2009 and 2011 Molina´s poverty rate dropped from 24.1 % to 13.5 % (national average 20.4 %); in this period the county went from insufficient to almost complete basic sanitation. Despite these advances, chemical pollutants in the food and air are increasing. Thus, in Molina risk factors typical of both under-developed and developed countries coexist, generating a unique profile associated with inflammation, oxidative stress and chronic diseases. MAUCO is the core project of the recently established Advanced Center for Chronic Diseases (ACCDiS), Universidad de Chile & Pontificia Universidad Católica de Chile. In this study, we are enrolling and following 10,000 adults aged 38 to 74 years over 10 years. All eligible Molina residents will be enrolled. Participants were identified through a household census. Consenting individuals answer an epidemiological survey exploring risk factors (psycho-social, pesticides, diet, alcohol, and physical activity), medical history and physical and cognitive conditions; provide fasting blood, urine, and saliva samples; receive an electrocardiogram, abdominal ultrasound and bio-impedance test; and take a hand-grip strength test. These subjects will be re-interviewed after 2, 5 and 7 years. Active surveillance of health events is in place throughout the regional healthcare system. The MAUCO Bio-Bank will store 30 to 50 aliquots per subject using an NIH/NCI biorepository system for secure and anonymous linkage of samples with data. MAUCO´s results will help design public health

    Among 2589 captive wild birds, examined between 1974 and 1983, we found leukosis in 26 birds belonging to 13 different species and five orders. We diagnosed lymphoid leukosis in 11 birds (two Melopsittacus undulatus, two Psittacus erithacus one Platycerus eximius, one Columba livia, one Streptopelia decaocto, one Polyplectron bicalcaratum, one Pavo cristatus, one Aptenodytes patachonia and one finch, species unknown), myeloid leukosis in 14 (nine Melopsittacus undulatus, two Agapomis personata fischeri, two Urgeainthus bengalus and one Neophemia pulchella) and stem cell leukosis in one bird (Serinus canaria). Among the cases with lymphoid leukosis we distinguished between lymphoblastic (four cases) and prolymphocytic forms (seven). Myeloid leukosis was subdivided into poorly differentiated (12 cases) and well differentiated myeloblastosis (two).

    2009-12-01

    An extracapsular stabilization technique was used to repair cruciate ligament ruptures in a trumpeter hornbill (Bycanistes bucinator) and an African grey parrot (Psittacus erithacus). The hornbill demonstrated cranial drawer motion and severe rotational instability of the stifle from ruptures of the cranial and caudal cruciate ligaments and stifle joint capsule. The luxation was reduced, and the fibula was cranially transposed, in relation to the tibiotarsus, and anchored with 2 positive profile threaded acrylic pins. A lateral extracapsular stabilization was then performed. The African grey parrot had a traumatic stifle luxation, and an open reduction and a lateral extracapsular stabilization were performed. Both birds regained function of the affected leg by 1 month after surgery. Extracapsular stabilization allows motion of the stifle joint to be maintained during the postoperative recovery period, an advantage over rigid stabilization. Maintaining motion in the stifle joint facilitates physical therapy and can aid in full recovery after avian stifle injuries.

    Ozone depletion by chlorofluorocarbons (CFCs) was first proposed by Molina and Rowland in their 1974 Nature paper. Since that time, the scientific connection between ozone losses and CFCs and other ozone depleting substances (ODSs) has been firmly established with laboratory measurements, atmospheric observations, and modeling research. This science research led to the implementation of international agreements that largely stopped the production of ODSs. In this study we use a fully-c...

    Full Text Available Resumen:En el artículo se presentan los resultados de una investigación comparativa de la evolución del proceso de reagrupación familiar de extranjeros no comunitarios en España, la Región de Murcia y el municipio de Molina de Segura en el período 2007-2014. Se analiza la evolución de la reagrupación familiar, mediante el acceso a fuentes secundarias. Para caracterizar el perfil del reagrupante se realizan entrevistas estructuradas al universo de solicitantes de informe de adecuación de vivienda para reagrupación familiar en Molina de Segura. Se aplica un cuestionario a extranjeros no comunitarios para describir las tendencias en reagrupación familiar en Molina de Segura y para conocer los conflictos surgidos en las familias reagrupadas se llevan a cabo entrevistas en profundidad a actores expertos y estratégicos. Los resultados evidencian que los cambios normativos y la actual crisis económica inciden, entre otros factores, a los procesos de reagrupación familiar. En este contexto es necesario incrementar los recursos destinados a los Servicios de Bienestar local para favorecer la integración real de las personas inmigrantes y mantener los niveles de cohesión social.

  10. Abundance of Conepatus chinga (Carnivora, Mephitidae and other medium-sized mammals in grasslands of southern Brazil

    Directory of Open Access Journals (Sweden)

    Carlos B. Kasper

    2012-09-01

    Full Text Available Between January 2007 and December 2010, the abundance of medium-sized mammals was studied, with special focus on the Molina's hog-nosed skunk, Conepatus chinga (Molina, 1782, at four locations in southern Brazil. In this study, transect line methodology was used to obtain data for Distance Analyses. Transects were traveled by car at night, searching with spotlights along the edges of secondary roads in agricultural landscapes. Along 1,811 km, we obtained 620 observations of 20 mammal species. The most common species was the exotic European hare, Lepus europaeus (Pallas, 1778; the highest abundance estimated for South America was observed in one of the study areas, where its density was estimated as 32 individuals/km². Carnivores were the most commonly recorded mammals, represented by 10 species and comprising 51% of all observations. Molina's hog-nosed skunk occurred in all study areas, but occurred in sufficient numbers to obtain density estimates in only two of the areas. We estimated 1.4 to 3.8 individuals/km², in the first density estimate made by the transect method for a member of Conepatus in the Neotropics. These values are similar to those estimated for North American species of Mephitidae. In Brazil, C. chinga is apparently more abundant in the Pampa biome than in the grasslands of the Atlantic Forest. For two other carnivores, Lycalopex gymnocercus (Fisher, 1814 and Cerdocyon thous (Linnaeus, 1766, we estimated preliminary densities that were similar to those previously cited for different regions.

  11. Revision of the Megaperidae Manter, 1934 n. comb. (Syn. Apocreadiidae Skrjabin, 1942) including a reorganization of the Schistorchiinae Yamaguti, 1942.

    Modified and/or new keys to the four subfamilies now recognized within the Megaperidae Manter, 1934 n. comb. (Syn. Apocreadiidae Skrjabin, 1942) as well as the genera within each subfamily are presented. Two new genera, Paraschistorchis n. gen. and Plesioschistorchis n. gen., both within the Schistorchiinae Yamaguti, 1942, are erected and keys are provided to the species considered in both new genera-distinguished by possessing caeca that end either in separate ani or blindly. Plesioschistorchis callyodontis (Yamaguti, 1942) n. comb. and Plesioschistorchis haridis (Nagaty, 1957) n. comb. are re-described from new material collected from the common parrotfish, Scarus psittacus Forsskål (Perciformes: Scaridae), inhabiting the Red Sea off Egypt; S. psittacus represents a new host record for both species. The taxonomic status of Schistorchis sensu stricto Lühe, 1906 is examined and revised, a key to the four species we consider in this genus offered, and the monotypic genus Megacreadium Nagaty, 1956 declared a junior synonym of Schistorchis. Members of Schistorchis sensu stricto possess a unique "complex" (i.e. highly cellular/glandular) instead of "simple" (i.e. entirely muscular) type of oral sucker that is quite large in relation to body size; an elongate, somewhat sub-rectangular-shaped body; 5+ testes arranged in at least two rows; caeca that open via separate ani; a long post-testicular region; a median genital pore either at the anterior margin of or just anterior to the ventral sucker; and species of Schistorchis sensu stricto parasitize the intestine of marine fish within the Order Tetraodontiformes Berg. With the revision of this genus, we re-describe Schistorchis carneus Lühe, 1906 from the lower and mid-intestine of the white-spotted puffer, Arothron hispidus (Linnaeus) (Tetraodontiformes: Tetraodontidae), collected in the Red Sea off Egypt. Finally, a plea is made for further study of the Megaperidae n. comb. focusing, in particular, on the following

  17. Genetic diversity and germplasm conservation of three minor Andean tuber crop species

    Directory of Open Access Journals (Sweden)

    Malice M.

    2009-01-01

    Full Text Available In traditional Andean agrosystems, three minor tuber crop species are of regional or local importance: oca (Oxalis tuberosa Molina, ulluco (Ullucus tuberosus Caldas and mashua (Tropaeolum tuberosum Ruiz and Pav.. Genetic diversity within these species is very large and could result from the high ecological and cultural variability that characterizes the Andean area. Nowadays, many anthropic or ecological factors cause the loss of diversity and contribute to genetic erosion. The development of conservation strategies for genetic resources of Andean tubers, in situ as well as ex situ, includes a better knowledge of diversity in addition to the study of Andean farming strategies linked to this genetic diversity.

    The use of co-digestion in wastewater treatment plants (WWTP) offers the possibility of treating sludge in conjunction with other substrates from different sources (agricultural or agroindustrial residues, etc.)to offset the balance of nutrients and moisture, increasing significantly biogas production of the process. Pobla de Farnals (Valencia) WWTP and Molina de Segura (Murcia) WWTP have introduced landfill leachate of municipal solid waste (MSW) in the anaerobic digestion, resulting in an increase of the biogas production. the additions started with punctual discharges of small amounts of leachate, and later, the frequency and volume of the discharges increased depending on the results.

  19. John Punch, Scotist Holy War, and the Irish Catholic Revolutionary Tradition in the Seventeenth Century.

    Science.gov (United States)

    Campbell, Ian W

    2016-07-01

    During the 1640s, the Irish Franciscan theologian John Punch taught his theology students in Rome that war against Protestants was made just by their religion alone. Jesuits like Luis de Molina identified the holy war tradition in which Punch stood as a Scotist one, and insisted that the Scotists had confused the natural and supernatural spheres. Among Irishmen, Punch was unusual. The main Irish Catholic revolutionary tradition employed Jesuit and Thomist theory. They argued that the Stuarts had lost the right to rule Ireland for natural reasons, not supernatural ones; because the Stuarts were tyrants, not because they were Protestants.

    2004-08-01

    An outbreak of cryptococcosis occurred in a breeding aviary in São Paulo, Brazil. Seven psittacine birds (of species Charmosyna papou, Lorius lory, Trichoglossus goldiei, Psittacula krameri and Psittacus erithacus) died of disseminated cryptococcosis. Incoordination, progressive paralysis and difficulty in flying were seen in five birds, whereas superficial lesions coincident with respiratory alterations were seen in two birds. Encapsulated yeasts suggestive of Cryptococcus sp. were seen in faecal smears stained with India ink in two cases. Histological examination of the birds showed cryptococcal cells in various tissues, including the beak, choana, sinus, lungs, air sacs, heart, liver, spleen, kidneys, intestines and central nervous system. High titres of cryptococcal antigen were observed in the serum of an affected bird. In this case, titres increased during treatment and the bird eventually died. Yeasts were isolated from the nasal mass, faeces and liver of one bird. Cryptococcus neoformans var. gattii serovar B was identified based on biochemical, physiological and serological tests. These strains were resistant (minimum inhibitory concentration 64 microg/ml) to fluconazole. This is the first report of C. neoformans var. gattii occurring in psittacine birds in Brazil.

    Chlamydiosis is one of the most important infectious diseases of birds. In this study, 253 clinical samples were taken from 27 bird species belonging to seven orders. Thirty-two (12.6%) samples were positive for Chlamydia psittaci major outer membrane gene (ompA) DNA by a nested polymerase chain reaction (PCR). Twelve nested PCR-positive specimens were typed by ompA gene-based PCR-restricted fragment length polymorphism, using CTU/CTL primers and AluI restriction enzyme. Four restriction patterns were identified, including genotype A (two specimens from an African grey parrot [Psittacus erithacus] and a lorikeet [Trichoglossus haematodus]), genotype B (two specimens from a rock dove [Columbia livia] and a canary [Serinus canaria]), a third new restriction pattern (six specimens from African grey parrots), and a fourth new restriction pattern (two specimens from a ring-necked parakeet [Psittacula krameri] and an Alexandrine parakeet [Psittacula eupatria]). The third and the fourth restriction patterns are suggested to be provisional genotypes I and J, respectively. Partial sequencing of the ompA gene of seven specimens completely correlated with the results of PCR-restricted fragment length polymorphism and confirmed the presence of genotypes A and B and the two new provisional genotypes I and J. The two new genotypes have the closest identity with C. psittaci genotype F and Chlamydia abortus, respectively. From an evolutionary perspective, both new genotypes, particularly genotype J, are intermediate between the two species, C. psittaci and C. abortus.

  9. Occurrence of Ornithonyssus sylviarum in pet birds from the district of Setúbal, Portugal.

    Waap, Helga; Paulino, Diana; Cardoso, Rita

    2017-07-01

    Ornithonyssus sylviarum is a blood-feeding ectoparasite of birds and the most serious pest in poultry farms in North America. Although the mites are typically adapted to temperate climates, information on this mite in Europe is sparse, and Dermanyssus gallinae is considered to be the only mite impacting the poultry industry. The present study reports the occurrence of O. sylviarum in pet birds in Portugal. Mites were collected directly from birds and with traps placed in cages and nests at 20 different sampling places belonging to 6 municipalities in the district of Setúbal. In a total of 217 birds, O. sylviarum was identified in 47 out of 147 (32.0%) canaries (Serinus canaria), 14 out of 21 (14.3%) estrildid finches, 1 out of 24 (4.2%) budgerigars (Melopsittacus undulatus) and 1 out of 15 (6.7%) lovebirds (Agapornis spp.). Mites of the genus Dermanyssus were identified in 8 canaries (5.4%), 8 estrildid finches (38.1%) and 1 lovebird (6.7%). No mites were found in 6 cockatiels (Nymphicus hollandicus), 2 African grey parrots (Psittacus erithacus), 1 Bourke's parrot (Neophema bourkii) and 1 rose-ringed parakeet (Psittacula krameri). Considering the zoonotic potential and the risk of dissemination to poultry, the present findings underline the need for further monitoring of O. sylviarum in the wild and domestic avifauna in Portugal.

  10. Feather-picking psittacines: histopathology and species trends.

    Science.gov (United States)

    Garner, M M; Clubb, S L; Mitchell, M A; Brown, L

    2008-05-01

    Histologic findings are described for 408 feather-picking or self-mutilating psittacines with the use of biopsies from clinically affected and unaffected skin. Inflammatory skin disease was diagnosed in 210 birds, and traumatic skin disease was diagnosed in 198 birds. Criteria used for the diagnosis of inflammatory skin disease included the presence of perivascular inflammation in the superficial or deep dermis of clinically affected and unaffected sites. The primary histologic criteria for the diagnosis of traumatic skin disease were superficial dermal scarring with or without inflammation in the affected sites and an absence of inflammation in the unaffected sites. The inflammatory cells associated with the lesions were typically lymphocytes and occasionally plasma cells, histiocytes, and granulocytes. A preponderance of inflammatory skin disease was seen in macaws (Ara spp.) and Amazon parrots (Amazona spp.). A preponderance of traumatic skin disease was seen in cockatoos (Cacatua spp.) and African grey parrots (Psittacus erithacus). The prevalence of each was approximately equal in several other species, including conures (Aratinga and Pyrrhura spp.), eclectus parrots (Eclectus roratus), quaker parrots (Myiopsitta monachus), cockatiels (Nymphicus hollandicus), parakeets (Cyanorhamphus and Psittacula spp.), and caiques (Pionites spp.). No geographic or gender-based trends were identified. These findings could be helpful for identifying and treating birds with feather-picking disorders.

    de Kloet, E; de Kloet, S R

    2004-12-01

    A study was made of the phylogenetic relationships between fifteen complete nucleotide sequences as well as 43 nucleotide sequences of the putative coat protein gene of different strains belonging to the virus species Beak and feather disease virus obtained from 39 individuals of 16 psittacine species. The species included among others, cockatoos ( Cacatuini), African grey parrots ( Psittacus erithacus) and peach-faced lovebirds ( Agapornis roseicollis), which were infected at different geographical locations, within and outside Australia, the native origin of the virus. The derived amino acid sequences of the putative coat protein were highly diverse, with differences between some strains amounting to 50 of the 250 amino acids. Phylogenetic analysis demonstrated that the putative coat gene sequences form six clusters which show a varying degree of psittacine species specificity. Most, but not all strains infecting African grey parrots formed a single cluster as did the strains infecting the cockatoos. Strains infecting the lovebirds clustered with those infecting such Australasian species as Eclectus roratus, Psittacula kramerii and Psephotus haematogaster. Although individual birds included in this study were, where studied, often infected by closely related strains, infection by highly diverged trains was also detected. The possible relationship between BFD viral strains and clinical disease signs is discussed.

    2018-01-01

    Beak and feather disease virus (BFDV), a member of genus circovirus, is a small, non-enveloped, single stranded DNA virus. Although BFDVs are among the most well studied circoviruses, there is little to no information about BFDVs in Iran. The aim of the present study was to detect and identify BFDV molecules from the birds referred to the avian clinic of The Faculty of Veterinary Medicine, Tehran University, Iran. A total of 55 DNA samples were extracted from birds from nine different species of the order psittaciformes. A robust conventional polymerase chain reaction (PCR) was applied to detect the rep gene of the virus. Ten out of 55 samples, from four different species, were tested positive for BFDVs in PCR ( Melopsittacus undulates (4), Psittacula Krameri (3), Psittacus erithacus (2), Platycercus eximius (1)). Molecular identification of the detected BFDVs was performed based on their rep gene sequences. The phylogenetic analysis revealed that the Iranian BFDVs from this study were clustered into four genetically distinct clades belonging to different genetic subtypes of BFDVs (L1, N1, T1, and I4). Although the relation between the samples and their related subtypes in the tree are discussed, further studies are needed to elucidate the host specificity and incidence of the BFDVs from different genetic subtypes.

  13. Higher-order semantic structures in an African Grey parrot's vocalizations: evidence from the hyperspace analog to language (HAL) model.

    Kaufman, Allison B; Colbert-White, Erin N; Burgess, Curt

    2013-09-01

    Previous research has described the significant role that social interaction plays in both the acquisition and use of speech by parrots. The current study analyzed the speech of one home-raised African Grey parrot (Psittacus erithacus erithacus) across three different social contexts: owner interacting with parrot in the same room, owner and parrot interacting out of view in adjacent rooms, and parrot home alone. The purpose was to determine the extent to which the subject's speech reflected an understanding of the contextual substitutability (e.g., the word street can be substituted in context for the word road) of the vocalizations that comprised the units in her repertoire (i.e., global co-occurrence of repertoire units; Burgess in Behav Res Methods Instrum Comput 30:188-198, 1998; Lund and Burgess in Behav Res Methods Instrum Comput 28:203-208, 1996). This was accomplished via the human language model hyperspace analog to language (HAL). HAL is contextually driven and bootstraps language "rules" from input without human intervention. Because HAL does not require human tutelage, it provided an objective measure to empirically examine the parrot's vocalizations. Results indicated that the subject's vocalization patterns did contain global co-occurrence. The presence of this quality in this nonhuman's speech may be strongly indicative of higher-order cognitive skills.

  14. Reply to Jaakkola (2014): "Do animals understand invisible displacement? A critical review".

    Science.gov (United States)

    Pepperberg, Irene M

    2015-05-01

    Jaakkola (2014) critiques studies that investigate nonhuman capacities to track objects undergoing invisible displacements. She states that the results of most of these studies are tainted by cuing, that conceptual understanding is lacking, and that, as a consequence, great apes are the only nonhumans to have full Stage 6 object permanence. Any critique, however, must clearly take into account all published information on the techniques being used, including more recent data that counter its negative claims. Furthermore, disagreements as to the interpretation of the underlying mechanisms, although common, need not always cast doubt on the actual findings reported. Here I present material with respect to Grey parrots (Psittacus erithacus) to counter Jaakkola's critique. First, I take issue with Jaakkola's claims of cuing, based both on data from newer studies and citations from the original material. Second, I discuss her suggestions that associative learning rather than inferential mechanisms underlie demonstrated performance, pointing out some difficulties in drawing clear lines between the 2 interpretations. In sum, I argue that Grey parrots, at least, do indeed succeed on tasks involving invisible displacement, and demonstrate full object permanence. (c) 2015 APA, all rights reserved).

  15. Do Birds Experience Sensory Pleasure?

    Directory of Open Access Journals (Sweden)

    Michel Cabanac

    2009-01-01

    Full Text Available To answer the question of whether sensory pleasure exists in birds, I trained an African-gray parrot (Psittacus erythacus named Aristote to speak. Stage 1 of the study consisted in gaining Aristote's affection. In Stage 2 Aristote was taught to speak, following Irene Pepperberg's triangular method: another person and I would talk together and look at Aristote only when it used understandable French words. Thus Aristote learned to say a few words for obtaining toys or getting my attention; e.g. “donne bouchon” (give cork or “donne gratte” (give scratch/tickle, with the appropriate reward. In Stage 3, the word bon (good was added to the short list of words used by Aristote. I said “bon” when giving Aristote the stimuli it requested and which would, presumably, be pleasurable; e.g. gratte bon. Aristote started to use short sentences such as “yaourt bon” (good yogurt. Eventually, Aristote transferred the word bon to new stimuli such as raisin (grape, an association I myself had never made. Such a use of vocabulary, and moreover its transfer, likely shows that this bird experienced sensory pleasure.

    2014-11-01

    Full Text Available Human-animal relations appear in various contexts (homes, farms, zoos, aquatic parks, etc. possibly favoring the emergence of the ability to understand heterospecific communication signals in several species. Studies show that dogs (Canis familiaris have developed the ability to attribute attention to humans, reading their body, head and gaze cues. Horses (Equus caballus and other species including African gray parrots (Psittacus erithacus show this ability too. Here, we asked if California sea lions (Zalophus californianus can discriminate the attentional state of their caretakers. Four sea lions were tested in three increasingly complex experiments requiring them to make a choice between an attentive versus an inattentive caretaker. The first test asked whether sea lions could attribute attention to a human facing them versus facing away. In the second test, the caretaker’s head orientation towards the sea lion served as the attentional cue. In the final test, the inattentive caretaker wore dark sunglasses. The results were heterogeneous and showed a higher rate of success than failure in the test 1, but the opposite in test 2. The results in the test 3 were not significant. Furthermore, the latency measures suggested that the subjects did not understand the tasks. It therefore appears that in the situation used here sea lions mainly focused their attention on the experimenter’s body orientation; the head did not seem to be a pertinent cue.

  17. Habitat Preferences of the Grey Parrot in Heterogeneous Vegetation Landscapes and Their Conservation Implications

    Full Text Available The wild Grey Parrot Psittacus erithacus Linnaeus suffers from many habitat use challenges in the wake of extensive deforestation in its endemic range of West and Central African rainforests. To determine effects of these challenges on the bird species, seasonal densities of the Grey Parrot were determined using line transects in major heterogeneous vegetation types in the Korup Rainforest, south-western Cameroon. Results of the study highlight habitat preferences of this species on a seasonal base and under different situations of human activity intensity in the landscape. This information can be used to understand the causes of changes in the distribution and abundance of endangered species and also to determine sustainable conservation strategies. It is concluded that the parrot needs diverse vegetation types for survival in the wild state, as it depends on specific tree species for specific habitat resources such as food, roosts, security, and nests at specific periods of the year. Hence, the continuous survival of the Grey Parrot in the range states is not certain, if sustainable measures are not taken to conserve the parrot and its habitat resources both in and outside protected areas.

  18. A new cryptic species of South American freshwater pufferfish of the genus Colomesus (Tetraodontidae, based on both morphology and DNA data.

    Cesar R L Amaral

    Full Text Available The Tetraodontidae are an Acantomorpha fish family with circumglobal distribution composed of 189 species grouped in 19 genera, occurring in seas, estuaries, and rivers between the tropical and temperate regions. Of these, the genus Colomesus is confined to South America, with what have been up to now considered only two species. C. asellus is spread over the entire Amazon, Tocantins-Araguaia drainages, and coastal environments from the Amazon mouth to Venezuela, and is the only freshwater puffers on that continent. C. psittacus is found in coastal marine and brackish water environments from Cuba to the northern coast of South America as far south as to Sergipe in Brazil. In the present contribution we used morphological data along with molecular systematics techniques to investigate the phylogeny and phylogeography of the freshwater pufferfishes of the genus Colomesus. The molecular part is based on a cytochrome C oxidase subunit I dataset constructed from both previously published and newly determined sequences, obtained from specimens collected from three distinct localities in South America. Our results from both molecular and morphological approaches enable us to identify and describe a new Colomesus species from the Tocantins River. We also discuss aspects of the historical biogeography and phylogeography of the South American freshwater pufferfishes, suggesting that it could be more recent than previously expected.

    Full Text Available Resumo: O presente ensaio propõe uma análise crítica do livro O Pós-Turismo, do mexicano Sergio Molina. Inicialmente, destacamos os métodos funcionalista, estruturalista e do materialismo histórico como instrumentos capazes de interpretar a realidade turística, mostrando seus avanços e limites, para, em seguida, discutir o conceito de pós-modernidade e o surgimento do sufixo “pós”. Assim, poderemos iniciar a discussão em torno do pós-turismo e explicitar o método utilizado por Molina para criar tal conceito e demonstrar como o mesmo contribui para o empobrecimento científico e acadêmico da teoria do Turismo, evidenciando que tal conceito aplica-se como uma construção voltada para o mercado e não para o saber turístico.

    1989-01-01

    The current knowledge of the chemistry of the stratosphere is reviewed, with particular consideration given to the measurements from the Atmospheric Trace Molecule Spectroscopy (ATMOS) experiment and from the Airborne Antarctic Ozone Experiment. Analysis of the ATMOS data at 30 deg N suggests that the current understanding of the contemporary-stratosphere chemistry at mid-latitudes is relatively complete, except for possible problems with the diurnal variations of N2O5 at low altitudes, and with ClNO3 at higher altitudes. Except for some difficulties with these two compounds, the data from ATMOS agree well with the gas phase models for nitrogen and chlorine species at 30 deg N in spring. It is emphasized that, in addition to the HOCl mechanism proposed by Solomon et al. (1986), the ClO-BrO scheme proposed by McElroy et al. (1986), and the ClO dimer mechanism introduced by Molina and Molina (1987), other processes exist that are responsible for ozone removal.

    The hydration rate constant of sulfur trioxide to sulfuric acid is shown to depend sensitively on water vapor pressure. In the 1:1 SO3-H2O complex, the rate is predicted to be slower by about 25 orders of magnitude compared with laboratory results [Lovejoy, E. R., Hanson, D. R. & Huey, L. G. (1996) J. Phys. Chem. 100, 19911–19916; Jayne, J. T., Pöschl, U., Chen, Y.-m., Dai, D., Molina, L. T., Worsnop, D. R., Kolb, C. E. & Molina, M. J. (1997) J. Phys. Chem. A 101, 10000–10011]. This discrepancy is removed mostly by allowing a second and third water molecule to participate. An asynchronous water-mediated double proton transfer concerted with the nucleophilic attack and a double proton transfer accompanied by a transient H3O+ rotation are predicted to be the fastest reaction mechanisms. Comparison of the predicted negative apparent “activation” energies with the experimental finding indicates that in our atmosphere, different reaction paths involving two and three water molecules are taken in the process of forming sulfate aerosols and consequently acid rain.

    2012-01-01

    Background Algae biofuels have been studied numerous times including the Aquatic Species program in 1978 in the U.S., smaller laboratory research projects and private programs. Results Using Molina Grima 2003 and Department of Energy figures, captial costs and operating costs of the closed systems and open systems were estimated. Cost per gallon of conservative estimates yielded $1,292.05 and $114.94 for closed and open ponds respectively. Contingency scenarios were generated in which cost per gallon of closed system biofuels would reach $17.54 under the generous conditions of 60% yield, 50% reduction in the capital costs and 50% hexane recovery. Price per gallon of open system produced fuel could reach $1.94 under generous assumptions of 30% yield and $0.2/kg CO2. Conclusions Current subsidies could allow biodiesel to be produced economically under the generous conditions specified by the model. PMID:22540986

    This study involved two commercial orchards located in Limarí Valley and Molina from two important Chilean production zones of extra virgin olive oil (EVOO). The investigation evaluated the effects of climate, soil composition, agricultural practices (fertilization and irrigation) and variety (considering two harvests) on the compounds responsible for the flavor of EVOO (volatiles and phenols) and how these compounds can explain the differences in chemical profiles by geographical origin, cultivar and fruit ripeness stage. Varieties from the Limarí Valley presented the highest content of phenolic compounds. A significant relationship (P Chilean regions have much more influence than cultivars on the concentration of sensory quality compounds. Difference in latitude between orchards increases the importance of the geographical origin on the virgin olive oil chemical composition while full irrigation decreases the impact of the cultivar. © 2015 Society of Chemical Industry.

    Immunisation against pathogens remains one of the most effective ways of preventing or reducing losses due to infectious diseases in animal husbandry. When inactivated vaccines are used, adjuvants are most often required to obtain satisfactory immune responses. One such type of adjuvant is saponin...... derived from the bark of Quillaja saponaria Molina, a tree of the rose family. A few different commercial sources exist, but due to the structural complexity and heterogeneity of these saponin preparations, it has been difficult to establish exactly which components are responsible for the adjuvant...... activity. By carefully selecting the bark source, live have succeeded in preparing a much less heterogeneous preparation of quillaja saponin. In this report we describe the preparation, in terms of structural complexity, hemolytic activity, adjuvant activity, and its ability to form ISCOM matrix. This new...

    This paper reports the first database on antioxidants contained in fruits produced and consumed within the south Andes region of South America. The database ( www.portalantioxidantes.com ) contains over 500 total phenolics (TP) and ORAC values for more than 120 species/varieties of fruits. All analyses were conducted by a single ISO/IEC 17025-certified laboratory. The characterization comprised native berries such as maqui ( Aristotelia chilensis ), murtilla ( Ugni molinae ), and calafate ( Barberis microphylla ), which largely outscored all other studied fruits. Major differences in TP and ORAC were observed as a function of the fruit variety in berries, avocado, cherries, and apples. In fruits such as pears, apples, apricots, and peaches, a significant part of the TP and ORAC was accounted for by the antioxidants present in the peel. These data should be useful to estimate the fruit-based intake of TP and, through the ORAC data, their antioxidant-related contribution to the diet of south Andes populations.

    Full Text Available In this paper, gender differences in Web 2.0 usage by postgraduate students in New Zealand are presented. 84 postgraduate students drawn from two different convenience samples were surveyed to discover the extent to which they used and were familiar with Web 2.0 applications. According to Cuadrado-García, Ruiz-Molina and Montoro-Pons (2010, p. 367, \\"men and women differ in their interaction with technology\\". In this study, gender differences in the use of different Web 2.0 applications and technologies have been considered. Whilst findings from this study are limited by the way in which the populations were sampled, the sample size and having a majority of international students with English as a second language, it is interesting to note that there were only minor differences between the ways in which male and female postgraduate students use Web 2.0 applications.

    Full Text Available A strategy to avoid nest predation by various bird species is the selection of inaccessible sites or sites of actual danger for potential predators. In this sense nesting near a top predator may be an effective strategy to avoid nest predation, if this predator does not have a preference for eggs or nestlings of the first species. This note reports the first record of nesting by Plain-mantled Tit-Spinetail (Leptasthenura aegithaloides Kittlitz, 1830 in an active nest of the variable Hawk (Geranoaetus polyosoma Quoy & Gaimard, 1824 and the nesting of the common diuca-finch (Diuca diuca Molina, 1782 nearby, during two consecutive years, in the Atacama Desert, Chile. This occurred during the “flowering desert” phenomenon in October of 2014 and September of 2015. We discuss hypotheses that may explain this biological association and its possible ecological implications.

Los personajes centrales de la novela, Luis Molina y Valentín Arregui, prueban que el camino para esa nueva humanidad debe pasar por una educación liberadora y una práctica consecuente.

    Full Text Available The present study shows the process followed in making the three-dimensional model and geometric documentation of a historical invention of the renowned Spanish engineer Agustin de Betancourt y Molina, which forms part of his rich legacy. Specifically, this was a wind machine for draining marshy ground, designed in 1789. The present research relies on the computer-aided design (CAD techniques using Autodesk Inventor Professional software, based on the scant information provided by the only two drawings of the machine, making it necessary to propose a number of dimensional and geometric hypotheses as well as a series of movement restrictions (degrees of freedom, to arrive at a consistent design. The results offer a functional design for this historic invention.

Somatic features and body measurements from available specimens belonging to these host-populations are compared with those recorded from Old World hosts, finding only some slight differences in certain body measurements (here interpreted as correlated to differences in host sizes, but none in chaetotaxy. This species was synoxenic with Myrsidea psittaci Carriker, 1955 on C. t. petersi in at least two localities in Buenos Aires Province, Argentina. Comparative studies of external chorionic architecture of the eggs, preferential sites of oviposition, prevalence has been carried out for both species, along with some remarks concerning the still problematic species, Myrsidea argentina (Kellogg, 1906, originally recorded off Carduelis magellanica (Vieillot, 1805.

    The saponin mixture QH-B from the tree Quillaja saponaria var. Molina was fractionated by RP-HPLC in several steps. The fractions were analyzed by solid-phase extraction NMR (SPE-NMR), a technique combining the workup by solid-phase extraction with on-line coupling to an NMR flow probe. Together with MALDI-TOF mass spectrometry and comparison with chemical shifts of similar saponins, the structures of both major and minor components in QH-B could be obtained. The procedure described is a simple method to determine the structure of components in a complex mixture. The two major fractions of the mixture were found to contain at least 28 saponins, differing in the carbohydrate substructures. Eight of these have not previously been determined. The 28 saponins formed 14 equilibrium pairs by the migration of an O-acyl group between two adjacent positions on a fucosyl residue.

    Full Text Available Blood hemoglobin oxygen affinity (P50 was measured in three Andean species and in the laboratory rat (control, all raised near sea level. Chinchilla lanigera (Molina, 1792 has an altitudinal habitat range from low Andean slopes up to 3000 m., while Chinchilla brevicaudata (Waterhouse, 1848 has an altitudinal range from 3000 to 5000 m. The laboratory type guinea pig, wild type guinea pig (Cavia porcellus, (Waterhouse, 1748, and laboratory rat (Rattus norvegicus were also raised at sea level. The Andean species had high hemoglobin oxygen affinities (low P50 compared with the rat. Chinchilla brevicaudata had a higher affinity than Chinchilla lanigera. The wild type guinea pig had a higher affinity than the laboratory type. As has been shown in other species, this is another example of an inverse correlation between the altitude level and the P50 values. This is the first hemoglobin oxygen affinity study in Chinchilla brevicaudata.

(2006) Proc Natl Acad Sci USA 103:16089-16094] claims to show that the Viking GCMS (gas chromatograph-mass spectrometer) experiment, which carried out a search for organic matter at the surface of Mars in 1976, "may have been blind to low levels of organics." To rebut this assertion, the Viking experiment, test data, and results on Mars are reviewed, and the fallacies in the design, execution, and interpretation of the new experiments presented by Navarro-Gonzalez et al. are critically examined.

    J. I. Rojas-Sola

    2018-04-01

    Full Text Available The objective of this research is to analyze the construction of the wind machine for draining marshy ground designed by Agustin de Betancourt and Molina in 1789. To do this, a static analysis by finite elements method from the threedimensional model obtained with Autodesk Inventor Professional has been performed. The results show that the greatest stresses of the mechanism take place when the main shaft is meshed with the cogwheel, namely the point of contact between the worm screw and cogwheel. However, the maximum displacements and the greatest deformations take place in the blades. In addition, the mechanism is oversized, reaching at no point the tensile strength of the material, confirming the successful construction of this historical invention.

  17. Avian influenza A viruses in birds of the order Psittaciformes: reports on virus isolations, transmission experiments and vaccinations and initial studies on innocuity and efficacy of oseltamivir in ovo.

    2007-07-01

    Birds of the order Psittaciformes are - besides chickens, turkeys and other birds - also susceptible to infection with avian influenza A viruses (AIV) and succumb following severe disease within one week. Published data prove that various parakeets, amazons, cockatoos, African grey parrots and budgerigars (genera Barnardius, Psittacula, Cacatua, Eolophus, Amazona, Myiopsitta, Psittacus and Melopsittacus) were found dead following natural infections. Natural infections of highly pathogenic avian influenza viruses (HPAIV) of the haemagglutinin subtypes H5 and H7 cause severe disease and high rates of mortality. Experimental transmission studies with AlVs of the subtypes H5 and H7 confirm these data. Viruses of the subtypes H3N8, H4N6, H4N8, H11N6 and H11N8 may cause also clinical signs and occasionally losses in naturally infected psittacine birds. Clinical signs and losses were also noted following experimental infection of budgerigars with a H4N6 virus. In the EU and in other countries, vaccination of exposed exotic and rare birds and poultry is a possible and an acceptable measure to provide protection. Currently, the EU Commission accepts inactivated adjuvanted vaccines whereas in some other countries recently developed vector vaccines are applied. However, birds remain susceptible during the time interval between application of any vaccine and the development of immunity. This critical period can be bridged with antiviral drugs. Our in ovo studies demonstrate that the neuraminidase inhibitor oseltamivir is non-toxic for chicken embryos at concentrations of 0.1, 1.0 and 10.0 mg/kg body weight. These dosages prevented entirely the replication of a HPAIV of the subtype H7N1 when this drug is given shortly prior to, simultaneously or soon after inoculation of chicken embryos with this AIV. Thus, we speculate that exposed valuable birds such as psittacines at risk can be successfully treated.

    A 5.5-year-old sexually intact female African Grey parrot (Psittacus erithacus) was evaluated for a 1-year history of pronounced polyuria and polydipsia. The bird also had a 1-month history of signs of mild depression and mydriasis. Physical examination revealed a thin body condition and incomplete bilateral mydriasis. Other examination findings as well as CBC and screening radiography results were unremarkable. Plasma biochemical analysis revealed mild hypernatremia. The bird had a 3.3% loss in body weight over 170 minutes during a water deprivation test, and urine osmolality remained low. After IM administration of 0.9 microg of desmopressin, the rate of weight loss decreased substantially and urine osmolality increased 300% over the following 200 minutes. Initial attempts to treat the bird with orally administered desmopressin failed to correct the polydipsia and polyuria. Ultimately, IM administration of 24 microg of desmopressin/kg (10.9 microg/lb) every 12 hours yielded a noticeable reduction in water consumption and urine production over a 6- to 8-hour period. Eight months later, the bird was returned for a recheck examination, at which time it was in good health and continued to respond to the medication. Despite continued response to the medication, right-sided internal ophthalmoparesis was detected 16 months after the initial diagnosis. To the authors' knowledge, central diabetes insipidus in birds has not been reported. The condition should be considered in birds with clinical signs of disease similar to those in mammals. Long-term IM administration of desmopressin may be a viable treatment option.

    Mucosal papillomas are relatively common lesions in several species of captive neotropical parrots. They cause considerable morbidity and in some cases, result in mortality. Previous efforts to identify papillomavirus DNA and proteins in these lesions have been largely unsuccessful. In contrast, increasing evidence suggests that mucosal papillomas may contain psittacid herpesviruses (PsHVs). In this study, 41 papillomas from 30 neotropical parrots were examined by PCR with PsHV-specific primers. All 41 papillomas were found to contain PsHV DNA. This 100% prevalence of PsHV infection in the papilloma population was found to be significantly higher than PsHV infection prevalence observed in other surveys of captive parrots. PsHV genotypes 1, 2, and 3, but not 4 were found in these lesions. Psittacus erithacus papillomavirus DNA and finch papillomavirus DNA were not found in the papillomas. A papilloma from a hyacinth macaw (Anodorhynchus hyacinthinus) was found to contain cells that had immunoreactivity to antiserum made to the common antigenic region of human papillomavirus (HPV) L1 major capsid protein. However, four other mucosal papillomas were negative for this immunoreactivity, and negative control tissues from a parrot embryo showed a similar staining pattern to that seen in the cloaca papilloma of the hyacinth macaw, strongly suggesting that the staining seen in hyacinth macaw papilloma was nonspecific. Based on these findings, it was concluded that specific genotypes of PsHV play a direct role in the development of mucosal papillomas of neotropical parrots and there is no evidence to suggest the concurrent presence of a papillomavirus in these lesions

    Papillomaviruses are epitheliotropic viruses that have circular dsDNA genomes encapsidated in non-enveloped virions. They have been found to infect a variety of mammals, reptiles and birds, but so far they have not been found in amphibians. Using a next-generation sequencing de novo assembly contig-informed recovery, we cloned and Sanger sequenced the complete genome of a novel papillomavirus from the faecal matter of Adélie penguins (Pygoscelis adeliae) nesting on Ross Island, Antarctica. The genome had all the usual features of a papillomavirus and an E9 ORF encoding a protein of unknown function that is found in all avian papillomaviruses to date. This novel papillomavirus genome shared ~60 % pairwise identity with the genomes of the other three known avian papillomaviruses: Fringilla coelebs papillomavirus 1 (FcPV1), Francolinus leucoscepus papillomavirus 1 (FlPV1) and Psittacus erithacus papillomavirus 1. Pairwise identity analysis and phylogenetic analysis of the major capsid protein gene clearly indicated that it represents a novel species, which we named Pygoscelis adeliae papillomavirus 1 (PaCV1). No evidence of recombination was detected in the genome of PaCV1, but we did detect a recombinant region (119 nt) in the E6 gene of FlPV1 with the recombinant region being derived from ancestral FcPV1-like sequences. Previously only paramyxoviruses, orthomyxoviruses and avian pox viruses have been genetically identified in penguins; however, the majority of penguin viral identifications have been based on serology or histology. This is the first report, to our knowledge, of a papillomavirus associated with a penguin species. © 2014 The Authors.

    Full Text Available A survey of carnivore mammals was accomplished in Aparados da Serra National Park from February 1998 to March 2000. The park has 10,250 ha and is considered a biodiversity core area of the Atlantic Forest Biosphere Reserve in the Rio Grande do Sul State, Brazil. The landscape is characterized by relatively well preserved relicts of Araucaria angustifolia (Bertol. Kuntze forest, grasslands and Atlantic Forest, which have contributed for the survival of endangered carnivore mammals. The National Park was divided in a grid of 16 km² cells using a 1:50,000 scale map. The animals were recorded using indirect methods, by identifying signs (scats, tracks and direct observation in 2.5 km long and 5 m wide transects, with 10 replicates in each grid cell. Interviews with local people were also used to confirm the animal presence. A total of 13 species was recorded: Procyon cancrivorus (Cuvier, 1798, Pseudalopex gymnocercus (G. Fischer, 1814, Leopardus pardalis (Linnaeus, 1758 and Cerdocyon thous (Linnaeus, 1766 were the most frequent species registered.

The Park presented areas with significant differences (Mantel Test, P< 0.05 in species richness and composition related to habitat classes. Areas with high habitat richness presented high species richness. The Araucaria forest was the habitat that presented the higher carnivore richness. The border areas of the Park are influenced by several environmental degradation factors that could be affecting the distribution of carnivores.

    Intertidal fish assemblages are thought to respond to tidal and diel rhythms although the assumption that these patterns are stable over long time scales (>1 year) is largely untested. Testing the validity of this assumption is necessary to assess whether short-term temporal patterns, once established, can be extrapolated over time and give a better understanding of the temporal dynamics of fish assemblages in coastal habitats. Here, we compare the fish assemblage structure from two intertidal mangrove creeks in North Brazil (Bragança Peninsula, Caeté estuary) sampled with the same sampling methodology (block nets), effort (two lunar cycles) and design (accounting for the combination of tidal and diel cycle) in the rainy seasons of 1999 and 2012 to evaluate the persistence, stability and recurrence of short-term patterns in the fish community organization. The interaction of tidal and diel cycles (inundations at spring tide-night, spring tide-day, neap tide-night, neap tide-day), found to be stable after 13 years, resulted in recurrent and stable intertidal mangrove fish assemblage compositions. The intertidal mangrove creek fish assemblage consisted of a persistent number of dominant species (seven). However, there were notable changes in fish catch mass, abundance and species dominance between 1999 and 2012. The most severe drought in North Brazil in 30 years, linked to lower precipitation and river runoff in the rainy season of 2012, may have resulted in (1) lower abundance of small juveniles of several dominant species in this assemblage (especially Ariidae - Cathorops agassizii and Sciades herzbergii) and (2) increased dominance of large-sized specimens of the tetraodontid Colomesus psittacus. Our findings highlight: (1) the overriding importance and stability of the interactive pulse of the tidal and diel cycles in determining short-term temporal patterns in intertidal mangrove fish assemblages in neotropical macrotidal estuaries despite the occurrence of

En la elaboración de las cronologías se utilizó el programa COFECHA para verificar el cofechado y se desarrolló para cada sitio una cronología utilizando el programa computacional ARSTAN. Se compararon las cronologías Contao y Mirador, con otras existentes para alerce encontrándose una alta similitud de la cronología Contao con la desarrollada para Lenca (41º 33'S, 72º 36' W. Contao presentó los valores más altos en los estadígrafos analizados con relación a las demás cronologías. Se observaron diferencias entre las cronologías provenientes de la Cordillera de la Costa y de los Andes en los últimos 150 años, probablemente producto de explotaciones humanas e incendios ocurridos en la cordillera de la Costa. La correlación con variables climáticas fue similar en su tendencia a la de otros estudios previos, documentando una correlación negativa con las temperaturas y positiva con las precipitaciones del verano anterior al período de crecimientoTwo ring-width chronologies were developed using samples from alerce (Fitzroya cupressoides (Molina Johnston. These were collected from two different sites; Contao, in the Andean Range and Mirador, in the Coastal Range. The series from the each site were cross-dated and COFECHA program was used to verify this process. Once correctly cross-dated, ARSTAN program was used to build up a chronology for each site (Contao and Mirador. These chronologies were compared with other existing chronologies. Contao presented the best statistics when compared to the other chronologies. Differences between chronologies from the Coastal and Andes Ranges were detected mainly during the last 150 years.

    Full Text Available This study aimed to evaluate the water depth selection during foraging, the efficiency in prey capture, and the food items captured by Casmerodius albus (Linnaeus, 1758 and Egretta thula (Molina, 1782. The work was conducted at an urban lagoon, Lagoa Rodrigo de Freitas, Rio de Janeiro. Four transects were made each month (two in the morning and two in the afternoon for six months. When the birds were detected foraging, the water depth and the types of prey captured were recorded. There was no significant relationship between the foraging efficiencies of the two species. However, they differed in relation to the water depth when foraging, and also in the food items captured. Casmerodius albus captured mainly fishes while Egretta thula captured mainly invertebrates. The results suggest that the differences in water depth when foraging and the food items captured allow a differential use of the food resources available by C. albus and E. thula at Lagoa Rodrigo de Freitas.Este estudo teve o objetivo de avaliar a seleção de profundidade durante o forrageamento, a eficiência na captura de presas e os itens alimentares capturados por Casmerodius albus (Linnaeus, 1758 e Egretta thula (Molina, 1782.

    Full Text Available RESUMEN: Partiendo de la afirmación de Levine y Molina (2006, según la cual la calidad de la democracia depende del funcionamiento de los procesos mediante los cuales la población selecciona y controla sus gobernantes, en este trabajo se examina el caso venezolano, haciendo especial énfasis en el análisis de la dinámica electoral del período marcado por la presidencia de Chávez (1999-2006. Dicho examen nos lleva a concluir que el régimen sociopolítico venezolano actual puede ser caracterizado más adecuadamente como un «régimen autoritario electoral», más que como una democracia representativa convencional. Los rasgos autoritarios del gobierno venezolano actual explicarían la baja puntuación obtenida por Venezuela en los índices de Freedom House. Sin embargo, este examen también nos lleva a considerar la pertinencia de los supuestos de la calidad de la democracia en el contexto de un cambio de régimen que explícitamente se aleja de las aspiraciones e ideales que sustentan el concepto, dimensiones e indicadores de la calidad de la democracia propuestos.ABSTRACT: Taking off from the affirmation by Levine and Molina that «the quality of democracy depends on the operation of procedures whereby the population selects and controls its government», this article examines the dynamics of elections during the Presidency of Chávez, (1999-2006. This examination leads to the conclusion that the current regime is better characterized as «an autoritarian electoral regime» than as a conventional representative democracy. This re-definition explains the low scores obtained by Venezuela both in Freedom House. At the same time, this study throws light on the bases of democracy and of definitions of quality of democracy in a regime that explicitly rejects the very ideals and aspirations that underlie the definitions, dimensions and indicators of democracy itself.

    Throughout the Andes Mountain range of South America a general trend of glacier shrinkage has taken place in the last century. Only a few glaciers have shown a rather non-continuous trend of glacier retreat and temporally advanced or even surged during the mid-19th to 20th century. One of the earliest assumed glacier surges has occurred in the upper Cachapoal catchment area at the homonymous glacier. In climatic respect the Cachapoal glacier is located in the transition zone from the most southern part of the Dry Central Andes of Chile to the more humid zone of the Wet Andes. The region is affected mainly by winter precipitation deriving from the Westerlies. The debris-covered, 12 km-long Cachapoal glacier represents one of the largest valley glaciers in the Central Andes. It is an avalanche-fed glacier with an almost 1500 m-high head wall in its upper catchment area flowing down from Picos del Barroso (5180 m) and terminates at an elevation of 2630 m a.s.l. with a bifurcated glacier tongue. A large moraine complex, almost 2 km in length and 500 m in width, separates the two glacier lobes. During times of advanced glacier tongue positions the Ríos Molina and Cachapoal may be have blocked independently at two distinct localities which are situated about 2300 m apart from each other. A blockage with temporal lake formation has occurred at least in the years 1848, 1955 and 1981 (cf. Plagemann 1887, Peña 1981), from which the rupture of the earliest glacier barrier has been the most devastating. This event is locally reminded as "la gran avenida en seco" in the historical record. Geomorphological evidence of the past historical and modern glacier expansions is given in the proglacial area by a fresh dead-ice hummocky topography and glacial trimlines at the valley flanks. More down valley broad outwash plains and boulder clusters indicate past high energy floods produced by glacier lake outbursts. Regarding the small size of the catchment area of the Río Molina

  20. AWARENESS LEVEL STUDY FOR IMPLEMENTING SEPARATION OF MUNICIPAL SOLID WASTE PROGRAM IN THE MUNICIPALITY OF ARANDAS, JALISCO

    Full Text Available The Arandas municipality government in Jalisco, has been looking for solutions to the problem of its municipal solid waste (MSW disposal for some years. Nowadays there is a “dumping site" where these residues are deposited without any established control, promoting the generation of vermin and rodents such as: flies, cockroaches, rats, mouses, etc.; adding up to the air, soil and water pollution. The solution starts with the separation of municipal solid waste from the generation sites, but it does not make any sense to separate the waste if there is not a subsequent treatment system established. The population awareness for garbage separation at home is quite necessary, because if it is not carried out correctly, it won’t be able to give an effective further treatment to the municipal solid waste MSW generated. In countries and municipalities where garbage separation is already practiced, it was because the community is forced to do so, whether their garbage is not collected if it is not properly separated, or by the implementation of economic fines. With the support of the H. Ayuntamiento de Arandas and José Mario Molina Pasquel and Henríquez Technological Institute Campus Arandas, was carried out a study to determine the level of awareness that the population of Arandas has about the necessity to separate garbage at home. For this purpose, a survey was designed and applied to parents or guardians of students from educational institutions: CONALEP Arandas, UDG Regional High School, CBTIS and José Mario Molina Pasquel and Henríquez Technological Institute Campus Arandas.

    Background: Most studies on endocrine-disrupting chemicals and breast cancer have focused on single compounds and have produced inconclusive findings. Objectives: We assessed the combined estrogenic effects of mixtures of xenoestrogens in serum and their relationship to breast cancer risk. Methods: A total of 186 incident pretreatment breast cancer cases and 196 frequency-matched controls were randomly sampled from a large population-based multicase–control study in Spain. The total effective xenoestrogen burden attributable to organohalogenated xenoestrogens (TEXB-α) and endogenous hormones and more polar xenoestrogens (TEXB-β) was determined in serum samples using high-performance liquid chromatography and E-Screen bioassay. Odds ratios for breast cancer comparing tertiles of serum TEXB-α and TEXB-β were estimated using logistic models, and smooth risk trends were obtained using spline models. Results: Cases had higher geometric mean TEXB-α and TEXB-β levels (8.32 and 9.94 Eeq pM/mL, respectively) than controls (2.99 and 5.96 Eeq pM/mL, respectively). The fully adjusted odds ratios for breast cancer (95% confidence intervals) comparing the second and third tertiles of TEXB-α with the first tertile were 1.77 (0.76, 4.10) and 3.45 (1.50, 7.97), respectively, and those for TEXB-β were 2.35 (1.10, 5.03) and 4.01 (1.88, 8.56), respectively. A steady increase in risk was evident across all detected TEXB-α levels and a sigmoidal trend was observed for TEXB-β. Individual xenoestrogens showed weak and opposing associations with breast cancer risk. Conclusions: This is the first study to show a strong positive association between serum total xenoestrogen burden and breast cancer risk, highlighting the importance of evaluating xenoestrogen mixtures, rather than single compounds, when studying hormone-related cancers.

    The aim of this work was to design new isotonic drinks with lemon juice and berries: maqui (Aristotelia chilensis (Molina) Stuntz), açaí (Euterpe oleracea Mart.) and blackthorn (Prunus spinosa L.), following previous research. Quality parameters, sensorial attributes, antioxidant activities (ABTS(+), DPPH(•) and O2(•-) assays) and biological capacities (α-glucosidase and lipase inhibitory assays) were evaluated over 70 days of shelf-life period. Maqui isotonic blends were the most active in all antioxidant assays (8.35 and 3.07 mmol L(-1) Trolox for ABTS(+) and DPPH(•)), in the lipase inhibitory assay (43.19 U L(-1)), and showed the highest total phenol content by the Folin-Ciocalteu test (80.97 mg 100 mL(-1) gallic acid), as a result of its higher content of total anthocyanins (42.42 mg 100 mL(-1)). Berry mixtures were also the most potent inhibitors of α-glucosidase between all samples, and displayed an attractive red colour and good sensorial attributes. All the studied parameters remained quite stable during preservation, in general, and the new isotonic drinks can be useful to equilibrate redox balance in acute and intense exercise, and support weight loss programmes, avoiding triglyceride absorption and hyperglycaemia involved in obesity and diabetes mellitus, respectively. Further research in vivo is necessary to verify their beneficial effects for sports, nutrition and health. © 2013 Society of Chemical Industry.

    Bacterial persistence is a transient, nonheritable physiological state that provides tolerance to bactericidal antibiotics. The stringent response, toxin-antitoxin modules, and stochastic processes, among other mechanisms, play roles in this phenomenon. How persistence is regulated is relatively ill defined. Here we show that cyclic AMP, a global regulator of carbon catabolism and other core processes, is a negative regulator of bacterial persistence in uropathogenic Escherichia coli , as measured by survival after exposure to a β-lactam antibiotic. This phenotype is regulated by a set of genes leading to an oxidative stress response and SOS-dependent DNA repair. Thus, persister cells tolerant to cell wall-acting antibiotics must cope with oxidative stress and DNA damage and these processes are regulated by cyclic AMP in uropathogenic E. coli IMPORTANCE Bacterial persister cells are important in relapsing infections in patients treated with antibiotics and also in the emergence of antibiotic resistance. Our results show that in uropathogenic E. coli , the second messenger cyclic AMP negatively regulates persister cell formation, since in its absence much more persister cells form that are tolerant to β-lactams antibiotics. We reveal the mechanism to be decreased levels of reactive oxygen species, specifically hydroxyl radicals, and SOS-dependent DNA repair. Our findings suggest that the oxidative stress response and DNA repair are relevant pathways to target in the design of persister-specific antibiotic compounds. Copyright © 2018 Molina-Quiroz et al.

    Full Text Available Leucism is an inherited disorder, characterized by the lack of pigments in part or all of the body, normal coloration of the eyes and, in birds, in naked parts such as the bill and legs. This kind of disorder is sometimes erroneously designated as albinism or partial albinism. In this study, we present a case of leucism in a wild owl. The studied individual presented completely white plumage, light-yellow coloration of legs and bill and normal coloration of eyes. According to morphological features, this owl is a specimen of burrowing owl, Athene cunicularia (Molina, 1782. To confirm the species identity, we used cytogenetic analyses for karyotypic determination, comparing it to the previously described one in the literature. We also studied a captive female of A. cunicularia to complement the species karyotype, which was described in the literature based only on a single male. The karyotype of the leucistic owl individual was compatible with the previously published one for A. cunicularia, confirming the bird was a male specimen. Cytogenetic analysis of the captive female showed that the W sex chromosome is metacentric and comparable to the seventh pair in size. This is the first description of a case of leucism in A. cunicularia for South America. Long-term studies are needed in the Neotropical region to evaluate survival and breeding success in leucistic birds.

    Saponins are used in medicine due to their pharmacological and immunological effects. To better understand interactions of saponins with model membranes and natural membranes of, for example, erythrocytes, Langmuir film balance experiments are well established. For most saponins, a strong interaction with cholesterol was demonstrated in dependence of both the aglycone part and the sugar moieties and is suggested to be correlated with a strong hemolytic activity, high toxicity, and high surface activity, as was demonstrated for the steroid saponin digitonin. In general, changes in the sugar chain or in substituents of the aglycone result in a modification of the saponin properties. A promising saponin with regard to fairly low hemolytic activity and high adjuvant effect is α -tomatine, which still shows a high affinity for cholesterol. An interaction with cholesterol and lipids has also been proven for the Quillaja saponin from the bark of Quillaja saponaria Molina. This triterpene saponin was approved in marketed vaccines as an adjuvant due to the formation of immunostimulating complexes. Immunostimulating complexes consist of a Quillaja saponin, cholesterol, phospholipids, and a corresponding antigen. Recently, another saponin from Quillaja brasiliensis was successfully tested in immunostimulating complexes, too. Based on the results of interaction studies, the formation of drug delivery systems such as immunostimulating complexes or similar self-assembled colloids is postulated for a variety of saponins.

    2013-01-01

    My aim in this paper is to briefly discuss the notion of identity and how can unify the Psychoanalytical concept with the discursive, in order to carry out multidisciplinary research on this topic. This work is based on life stories collected in the Hospital Larcade, from 2008 to 2011, from teenagers who attend a pregnancy. Through the linguistic analysis of the guarantees, following the model of Toulmin (17), as it has been redefined by Pardo (14) and Molina (12), I intend to give an account of the discursive and psychological bases of what will then form an identity for these young women on maternity. They live in extreme poverty in the Buenos Aires suburbs and are combined with a large dose of family violence that links their identities as mothers to the image (or identities of the other) who have over their own mothers, parents, couples in these contexts of violence. These data are also confronted with domestic violence cases that appear in the media and how they are dealt with discursively at these. Thus realizes the contradictions imposed the cultural identity of a group (the viewers or readers of means, which are a large part of society) against the experience of violence of these mothers. This research has as theoretical framework the Critical Discourse Analysis and the methodology is qualitative.

    In Colombia, the natural intermediate host of Echinococcus vogeli Rausch and Bernstein, 1972 is the paca, Cuniculus paca L. (Rodentia: Dasyproctidae). The larval cestode develops in the liver of the host, where it usually is situated superficially, partly exposed beneath Glisson's capsule. The infective larva consists of a subspherical to asymmetrical, fluid-filled vesicle, up to 30 mm in diameter, enclosed by a thick laminated membrane. It typically contains numerous chambers, often interconnected, produced by endogenous proliferation of germinal and laminated tissue, within which brood capsules arise in an irregular pattern from the germinal layer. Invasive growth by means of exogenous proliferation, typical of infections in man, was not observed in the natural intermediate host. The development of the larval cestode is described on the basis of material from pacas, supplemented by observations on early-stage lesions in experimentally infected nutrias, Myocastor coypus (Molina) (Rodentia: Capromyidae). The tissue response is characterized for early-stage, mature (infective), and degenerating larvae in the comparatively long-lived intermediate host. In addition to previously reported differences in size and form of rostellar hooks, other morphologic characteristics are defined by which the larval stage of E. vogeli is distinguished from that of E. oligarthrus (Diesing, 1863). Pathogenesis by the larval E. vogeli in man, like that by the larval E. multilocularis Leuckart, 1863, is the consequence of atypical proliferation of vesicles attributable to parasite-host incompatibility.

    Methane accounts for roughly 20% of the global radiative climate forcing in the last two and a half centuries. Methane emissions arise from a number of anthropogenic and biogenic sources. In some areas enteric fermentation in livestock produces over 90% of agricultural methane. In the spring of 2013, as a part of the Short Lived Climate Forcer-Mexico field campaign, the Aerodyne Mobile Laboratory in partnership with the Molina Center for the Environment studied methane production associated with enteric fermentation in the rumen of cattle. A variety of different breeds and stocks being raised in two agricultural and veterinary research facilities located in different areas of Mexico were examined. Methane fluxes were quantified using two methods: 1) an atmospherically stable gaseous tracer release was collocated with small herds in a pasture, allowing tracer ratio flux measurements; 2) respiratory CO2 was measured in tandem with methane in the breath of individual animals allowing methane production to be related to metabolism. The use of an extensive suite of very high time response instruments allows for differentiation of individual methane producing rumination events and respiratory CO2 from possible background interferences. The results of these studies will be presented and compared to data from traditional chamber experiments.

The present study analyzes biometric relationships, growth parameters and somatic production using the ELEFAN I routine and the Crisp’s method. During the year 2004 the rate of exploitation (E= 0.69 y-1 was significantly bigger than the values of 2003 and the monthly landings (maximum of 335 t and fishing effort (maximum of 848 trips were twice increased. These changes induced in the same year a significant decrease of population mean density (D= 54.13 ind. m-2 and the halfway reduction of somatic production (P= 81.99 gAFDW m-2 y-1 and P/B rate (0.38 y-1 values, regarding the values of the previous year. Also, a significant increment of total mortality rate (2.84 y-1 and the fishing mortality rate (1.97 y-1 were twice increased, regarding the previous year. It is assumed that the population of razor clams already was a overfishing commercial resource in the 2003 and that the increment of fishing pressure in the 2004, particularly during the second semester, intensified its overfishing resource condition.

It was applied to a fully randomized design with factorial arrangement without interaction 4 x 3 (3 nutritive solutions + 1 control (water x 3 harvesting time and 3 repetitions per treatments. The highest yields in terms of dry matter (137 and 114 kg DM/m2/year and crude protein (21,3 y 15,5 kg CP/m2/year were reached with the Hoagland and FAO solutions at 12 days of age, respectively. It was concluded that the best harvesting time independently of the nutritive solution was at 12 days and in all harvesting time the Hoagland and FAO solutions showed the best agronomic and chemical results.

  19. Evidence for absorption of kelp detritus by the ribbed mussel Aulacomya ater using a new 51Cr-labelled microsphere technique

    A modification of the 51 Cr: 14 C twin-labelling technique is described in which the food source is labelled with 14 C but the 51 Cr is enclosed in a polymeric resin membrane and presented as microspheres of a similar diameter to the food particles. This eliminates the major uptake of 51 Cr which is transferred to the ctenidia and palps of the suspension-feeding mussel Aulacomya ater (Molina) from detritus labelled with 51 Cr. The results suggest that althoug bacterial cultures based on isolates of kelp bacteria can be absorbed with an efficiency of 67 to 70%, the debris itself is also absorbed with an efficiency of approximately 50%. The kelp debris, which forms an important component of the particulate matter potentially available for consumers, may thus represent an important source of carbon for the filter feeding community adjacent to kelp beds. In contrast to the results obtained in other studies with artificial food sources, the data for kelp debris suggest that A. ater is able to maintain a positive scope for grwoth at the concentrations of suspended organic matter which occur under natural conditions in the kelp bed environment.

    Applying the model of the Perceptron multilayer with momentum of an artificial neural network particularly and a multispectral image of high resolution spatial and radiometric, for the first time estimated the salinity of the soil cultivated with sugar cane. The study area is the UBPC 'Lazaro Romero' of the sugar company 'Hector Molina' of the locality San Nicolas de Bari, Havana province, located at 22° 44' North latitude and 81 ° 56' longitude West. The experiments were made in the framework of the El-479 project funded by the Inter universities Council of Flanders, Belgium. 36 samples geo referenced of soils were taken at 3 depths in each of the 4 sugar cane selected blocks, which determined the electrical conductivity of the saturation extract; half of that amount of data was used for the training of the network and the other half for control in a computer program of the artificial neural network created to that effect, together with the reflectance of vegetation indexes for the image, which were maps of electrical conductivity of each block and bands. They were compared with those obtained by simple linear regression between the normalized difference vegetation index and electrical conductivity, Ndv with the approach of the neuronal network, the correlation coefficient was 0.78 to 0.83, while the linear regression was between 0.65 to 0.75

    Full Text Available We present a study about teacher accreditation in rural education at the Federal University at Tocantins (UFT. We analyzed the political and pedagogical aspects of the implementation of the course. We debated the protagonism of social movements in struggles for the right to education and in issues related to higher education policies for rural areas in Brazil. The methodological approach was inspired by oral history, using a qualitative approach. We interviewed teachers who participated in the implementation of the course at UFT, to grasp the expectations and constructions undertaken in the materialization of the accreditation course. The theoretical basis of this study involved a dialogue with authors such as: Caldart, Santos, Molina, Arroyo, Silva and Alberti. We discuss the pedagogy of alternance as a reference to the quality of alternance sought for the accreditation program for rural education and proposals for its enactment. We find that the implementation of the accreditation course in rural education represents an achievement for the population living in rural areas and is in a process of construction, which requires that its organizers adopt new positions in relation to conflicts and confrontations involved in its realization.

Se registraron en video treinta díadas de estudiantes desconocidos entre sí en interacciones que tuvieron una manipulación orientada a generar una situación empática o bien no-empática. Se seleccionaron cuatro segmentos de conversación, dos por cada tipo de interacción. El texto fue analizado con un protocolo de análisis semiótico basado en el modelo de análisis propuesto por (Molina, 2007. Los resultados muestran que las interacciones empáticas se caracterizan por un proceso de coconstrucción de significados, con una adecuada administración de la tensión y una identificación con el signo lingüístico. Por otra parte, las interacciones no empáticas se caracterizan por la emergencia de signos lingüísticos que no continúan la secuencia de construcción de significados; con una alta tensión dialógica, y una estrategia de distanciamiento o abandono del campo de significado.

    Full Text Available Abstract Despite being a bird with a broad and extensive distribution in Chile, the black-chinned siskin, Spinus barbatus Molina, 1782 is not well studied in relation to its parasites. This paper aims to describe the ectoparasite fauna of S. barbatus in central and southern Chile. A total of 125 individuals caught with mist nets were examined alive; a total of 22 parasites were found dead and were exposed to parasit autopsy. The extracted parasites were preserved in 70% alcohol for subsequent mounting and identification. Ectoparasites were found in 56 black-chinned siskins (38%; 48 of them (33% had 870 mites – 680 feather mites (Astigmata: Analgoidea were identified as Proctophyllodes spini, 167 as Knemidokoptes jamaicensis, 19 as Strelkoviacarus critesi, and one as Analges passerinus. Moreover, three mites were chiggers belonging to the tribe Schoengastiini (Prostigmata: Trombiculidae. In 21 birds (14%, 54 lice were found, 21 of which were identified as Philopterus roehreri, 18 as Myrsidea serini, and 15 as Ricinus carolynae. Endoparasites were not found in the necropsied individuals. All of the parasites that were found represent new records for Chile, and they also serve as new records of host–parasite associations for S. barbatus.

    In the battle to help developing countries overcome threats from declining food production caused by climate change, one species of edible grain-like crop has caught international attention because of its unique nutritional value. New and improved varieties of quinoa, historically grown in the highlands of South America, will be made available to farmers in mutations adapted to challenging environments in Bolivia and Peru. Increased genetic diversity is the result of the use of nuclear techniques in collaboration with the IAEA and the Food and Agriculture Organization of the United Nations (FAO), said L. Gomez-Pando, Principal Professor and Head of the Cereals and Native Grains Research programme at the National Agrarian University of La Molina in Peru. “There are 64 mutant lines of quinoa selected by yield potential and quality for the market,” he said. “These mutant lines will be further evaluated and the best lines will be released as new varieties in 2015–2016.”

    Full Text Available Culture, particularly cinema, drama and music, played a key role in order to keep and reinforce the identity of Spanish migrants in Argentina and Mexico during the first part of the 20th century. For decades, these countries had received thousands of migrants from Spain, and by the period following the Spanish Civil War (1936-1939 a notable colony of them settled in Buenos Aires and Mexico City. At the same time, several artists arrived to these places escaping from the war, political repression or, simply, looking for new work opportunities. For instance, famous singers, actors and flamenco players and dancers (v.g. Miguel de Molina, Angelillo, Niño de Utrera, or Sabicas achieved overwhelming successes in Buenos Aires and Mexico City’s theatres. Even more, they created a parallel Spanish stardom abroad. Hence, this proposal summarizes the contribution of some of these artists and the fusion between theatre and cinema, and typical Andalusian music as flamenco to preserve and evoke the collective memory of such a faraway motherland. Since Andalusia (the Southern region of Spain and its culture acted as a metonymic resource to represent that country during that period, migrants from different regions could recognize a common notion of the Spanish identity in them. In this sense, ‘home’ could be staged, remembered, fictionalized and, obviously, idealized.

    Frank Sherwood Rowland, known to his friends and colleagues as Sherry, died at his home in Corona del Mar, Calif., on 10 March 2012. He was 84. A Nobel Prize-winning atmospheric chemist, Sherry codiscovered the role of chlorofluorocarbons (CFCs) in stratospheric ozone depletion, researched the accumulation of greenhouse gases on a planetary scale, and tirelessly communicated the global consequences of human activity to policy makers and the public. Sherry had a calm, gentle demeanor and was as respected for his integrity and humility as for his groundbreaking scientific achievements. Sherry was a long-time member and Fellow (1980) of AGU and received the AGU Roger Revelle Medal in 1994 for his substantial contributions to the awareness of global change. The following year, he shared the Nobel Prize in Chemistry with Mario Molina and Paul Crutzen for their pioneering contributions to atmospheric chemistry, particularly the formation and decomposition of stratospheric ozone. In its citation, the Nobel Committee commended them for contributing to "our salvation from a global environmental problem that could have catastrophic consequences."

    This study aims at investigating the affective and cognitive components of empathy in relation to both emotion comprehension and prosocial/hostile behaviors in preschoolers. A total of 219 children (54% boys; aged between 3 and 6: mean age 4.10) and 20 teachers (two for each class: group A and group B) took part in this research. Pupils' empathy and hostile/prosocial roles were assessed by teacher reports [Belacchi and Farina, 2010] and children's emotion comprehension by a nonverbal test [Test of Emotion Comprehension: Pons and Harris, 2000; adapted by Albanese and Molina; 2008]. As expected, the results showed a significant influence of gender, with girls being more empathic than boys, according to all of the teachers' perception. Contrary to our expectations, no systematic age influence emerged. Regarding the relations of children's emotion comprehension with both empathy measures and their prosocial/hostile attitudes, we have found: (1) a low significant relation with the total empathy measure, according to all the teachers, but with the cognitive empathy only according to teachers B; (2) a robust negative relationship of both affective and cognitive empathy with Hostile roles and with Outsider role, contrary to a positive correlation of only affective empathy with Prosocial roles. No relationships emerged between empathy measures and Victim role. © 2012 Wiley Periodicals, Inc.

    The experience of staff in treating adolescent pregnancy and the formidable problems (medical, educational, nutritional, and emotional) these girls face are discussed. The implementing agency was the Centro de Medicina Reproductiva del Adolescente (CEMERA) in Santiago, Chile. One 15-year old girl is reported to have felt comfortable at CEMERA because of friendships with other similarly pregnant girls. The director, Dr. Ramiro Molina, established CEMERA with a comprehensive approach to adolescent reproductive health; there was also sex education, medical student training, and research. The program began in 1981 as a research project and included a center of 1990. Presently, CEMERA treats about 1800 low-income adolescents/year, of whom 80% are female. The problem of teenage sexuality and pregnancy was identified in a 1988 survey, which revealed that 70% of first births in the 15-24 year old age group were out of wedlock, and 20% or fewer used contraceptives at first premarital intercourse. The program currently not only provides care for adolescents, but also gives workshops and assistance to partners and parents, and contraceptive counseling to young men and women. Most services are free. There has been an increase in clinics addressing adolescent reproductive health from 2 in 1981 to more than 95 presently; most of the health personnel in the current settings have been trained by CEMERA CEMERA is located in converted row houses in central Santiago, and provides an informal setting less threatening to adolescents. The traditional white medical clothes are not used very often.

    Full Text Available High temperatures affect potato production in the tropics, putting tuber yield and quality at risk and leading to increased glycoalkaloid concentration the cause of the bitter taste in potatoes and a cause for concern for human health. The International Potato Center (CIP, has developed new heat tolerant clones which are heat tolerant and also resistant to late blight. These clones offer an opportunity to evaluate yield and glycoalkaloid levels after growth under high temperature environments. We evaluated four sets of 16 full-sib families and 20 clones for tuber yield and glycoalkaloid content in order to estimate narrow-sense and broad-sense heritability respectively. We used a randomized complete block design replicated in three locations in Peru; San Ramon, La Molina and Majes At harvest, the number and weight of marketable and nonmarketable tubers were recorded. We analyzed samples of tubers from each clone for glycoalkaloid content using spectrophotometry. Narrow-sense heritability for tuber yield, tuber number and average tuber weight were 0.41, 0.50 and 0.83, respectively, indicating that further gains in breeding for heat tolerance will be possible. Broadsense heritability for glycoalkaloid content was 0.63 and correlation with tuber yield was weak, r=0.33 and R²=0.11 (P<0.01. High heritability and weak correlation will allow us to select clones with high tuber yield and low glycoalkaloid content, to serve as candidate varieties and parents in breeding programs.

    The objectives of this funded project were (a) to further analyze the data collected by our group and collaborators in Mexico City during the MCMA-2003 field campaign, with the goal of further our understanding of aerosol sources and processes; and (b) to deploy several advanced instruments, including the newly developed high-resolution time-of-flight aerosol mass spectrometer (HR-ToF-AMS) and thermal-denuder (TD), during the MILAGRO/MAX-Mex/MCMA-2006 field campaign, and to analyze those data (together with the 2003 data) to provide additional insights on the formation and transformation of aerosols in the Mexico City area. These goals were addressed in collaboration with our project partners, MIT/Molina Center, and Aerodyne Research. Overall this project was very successful, resulting on 22+ journal papers including six “highly cited papers” and three papers that are the most cited in their respective journals (out of several thousand papers) since the year in which they were published. Multiple discoveries, such as the the underestimation of SOA in urban areas even for short photochemical ages, the demonstration that urban POA is of similar or higher volatility than urban SOA, and the first analysis of organic aerosol elemental composition in real-time have been recently published. Several dozen presentations at major US and international conferences and seminars also acknowledged this grant.

    Cecilia P. Calabuig

    2013-08-01

    Full Text Available The Coscoroba Swan, Coscoroba coscoroba (Molina, 1782, is a poorly known aberrant Anserine endemic to South America. We captured adult birds (189 male, 157 female from the largest population in Brazil at the Taim Ecological Reserve, State of Rio Grande do Sul, Brazil. Different patterns between sexes can reflect differences in selection, and positive allometry may indicate that a character is sexually selected. We used body weight and 10 morphological measurements to examine allometric differences between males and females of C. coscoroba. Males were consistently larger than females. Analysis of scaling relationships against body mass showed that nostril, tail, wing and bill height were positively allometric (i.e., heavier birds had relatively larger character lengths, but there were no sexual differences in allometric slopes. However, for a given mass, mature females had longer tails, longer wings (up to metacarpophalangeal articulation and shorter heads than males. In the light of current debate in the literature, we discuss whether such positively allometric traits and sexual differences in scaling may be indicative of sexual selection. Although Coscoroba Swan is a monogamous species, increasing the size of some attributes may confer some advantage for mate selection or male-male competition and, contrary to other studies, we suggest that positively allometric slopes alone should not be considered as evidence for sexual selection of the considered traits.

    Emshwiller, Eve; Doyle, Jeff J

    2002-07-01

    In continuing study of the origins of the octoploid tuber crop oca, Oxalis tuberosa Molina, we used phylogenetic analysis of DNA sequences of the chloroplast-active (nuclear encoded) isozyme of glutamine synthetase (ncpGS) from cultivated oca, its allies in the "Oxalis tuberosa alliance," and other Andean Oxalis. Multiple ncpGS sequences found within individuals of both the cultigen and a yet unnamed wild tuber-bearing taxon of Bolivia were separated by molecular cloning, but some cloned sequences appeared to be artifacts of polymerase chain reaction (PCR) recombination and/or Taq error. Nonetheless, three classes of nonrecombinant sequences each joined a different part of the O. tuberosa alliance clade on the ncpGS gene tree. Octoploid oca shares two sequence classes with the Bolivian tuber-bearing taxon (of unknown ploidy level). Fixed heterozygosity of these two sequence classes in all ocas sampled suggests that they represent homeologous loci and that oca is allopolyploid. A third sequence class, found in eight of nine oca plants sampled, might represent a third homeologous locus, suggesting that oca may be autoallopolyploid, and is shared with another wild tuber-bearing species, tetraploid O. picchensis of southern Peru. Thus, ncpGS data identify these two taxa as the best candidates as progenitors of cultivated oca.

    Full Text Available The article seeks to develop and apply new quantitative measurement instruments capable of significantly improving understanding of the relationship between the transnational mobility and transnational social ties of students, along with their reflexive capacities. With a focus on students building their personal networks, educational and professional activities that extend beyond the nation’s borders and organising their day-to-day routines in transnational social spaces, we analyse the role of mobility in their reflexive capacities. Applying a tool that is line with Archer’s theory and indicators to measure reflexivity, and transnational social ties as proposed by Molina et al., we analyse data collected via an on-line survey questionnaire administered to Slovenian students. In addition, students from the Middle East (Lebanon and the USA (Hawai’i are added for comparative purposes. The results of path analysis show the Slovenian students’ mobility as such implies higher scores for meta reflexivity, combined with lower scores for communicative and fractured reflexivity. Further, social transactions reaching beyond one’s physical localities in terms of transnational social ties implies they have higher levels of reflexivity in general.

    A method for separation and detection of major and minor components in complex mixtures has been developed, utilising two-dimensional high-performance liquid chromatography (2D-HPLC) combined with electrospray ionisation ion-trap multiple-stage mass spectrometry (ESI-ITMS(n)). Chromatographic conditions were matched with mass spectrometric detection to maximise the number of components that could be separated. The described procedure has proven useful to discern several hundreds of saponin components when applied to Quillaja saponaria Molina bark extracts. The discrimination of each saponin component relies on the fact that three coordinates (x, y, z) for each component can be derived from the retention time of the two chromatographic steps (x, y) and the m/z-values from the multiple-stage mass spectrometry (z(n), n=1, 2, ...). Thus an improved graphical representation was obtained by combining retention times from the two-stage separation with +MS(1) (z(1)) and the additional structural information from the second mass stage +MS(2) (z(2), z(3)) corresponding to the main fragment ions. By this approach three-dimensional plots can be made that reveal both the chromatographic and structural properties of a specific mixture which can be useful in fingerprinting of complex mixtures. 2009 Elsevier B.V.

    Full Text Available The Holy Qur’an has been translated into many languages including English. However, different translator of the Holy Qur’an produces different English version of Al-Qur’an because every translator uses different translation techniques to translate Al-Qur’an. This study aims to compare the three English versions of Arrahman surah, and describe the most dominant translation techniques used by the three translators to translate the Holy Qur’an. Translation techniques proposed by Molina and Albir (2002, p.509-511 are used to analyze the data. The data for this study are words, phrases, and clauses in the 78 verses of Arrahman surah in Arabic and its three English versions translated by Maulawi Sher ‘Ali, Dr. Muhammad Taqi­ud­Din Al­Hilali and Dr. Muhammad Muhsin Khan, and Talal Itani. The result shows that there are four most dominant techniques used by the three translators in translating the Holy Qur’an; Adaptation, Amplification, Established Equivalent, and Literal Translation technique. The first and the second translator prefer to use Amplification to introduce details in brackets or footnotes, but the third translator prefers to use Established Equivalent to find a term or expression recognized (by dictionaries or language in use as an equivalent.

    Full Text Available Le bandit catalan est un personnage que l’on rencontre fréquemment dans la littérature espagnole du Siècle d’Or et des auteurs tels que Cervantès, Lope de Vega et Tirso de Molina se sont beaucoup intéressés à lui à une époque où le banditisme resurgit avec force en Espagne. Le poncif littéraire présente de nombreux points communs avec le stéréotype social tel qu’il est représenté dans les documents contemporains qui exposent les origines du phénomène. Il est dans les deux cas dépeint comme un justicier qui n’écoute que ce que lui dicte son honneur. Toutefois, il s’agit d’une vision déformée de la réalité qui pose un problème d’interprétation : comment expliquer que les auteurs espagnols du XVIIe siècle aient pu voir dans ce criminel un modèle de vertu ?

Very large temperature decreases are observed in response to circulation changes and decreased shortwave radiation absorption by ozone. Ozone levels in the tropical lower strat osphere remain constant until about 2053 and then collapse to near ze ro by 2058 as a result of heterogeneous chemical processes (as curren tly observed in the Antarctic ozone hole). The tropical cooling that triggers the ozone collapse is caused by an increase of the tropical upwelling. In response to ozone changes, ultraviolet radiation increa ses, more than doubling the erythemal radiation in the northern summer midlatitudes by 2060.

    The 'Oxalis tuberosa alliance' is a group of Andean Oxalis species allied to the Andean tuber crop O. tuberosa Molina (Oxalidaceae), commonly known as 'oca'. As part of a larger project studying the origins of polyploidy and domestication of cultivated oca, flow cytometry was used to survey DNA ploidy levels among Bolivian and Peruvian accessions of alliance members. In addition, this study provided a first assessment of C-values in the alliance by estimating nuclear DNA contents of these accessions using chicken erythrocytes as internal standard. Ten Bolivian accessions of cultivated O. tuberosa were confirmed to be octoploid, with a mean nuclear DNA content of approx. 3.6 pg/2C. Two Peruvian wild Oxalis species, O. phaeotricha and O. picchensis, were inferred to be tetraploid (both with approx. 1.67 pg/2C), the latter being one of the putative progenitors of O. tuberosa identified by chloroplast-expressed glutamine synthetase data in prior work. The remaining accessions (from 78 populations provisionally identified as 35 species) were DNA diploid, with nuclear DNA contents varying from 0.79 to 1.34 pg/2C.

As part of a larger project studying the origins of polyploidy and domestication of cultivated oca, flow cytometry was used to survey DNA ploidy levels among Bolivian and Peruvian accessions of alliance members. In addition, this study provided a first assessment of C‐values in the alliance by estimating nuclear DNA contents of these accessions using chicken erythrocytes as internal standard. Ten Bolivian accessions of cultivated O. tuberosa were confirmed to be octoploid, with a mean nuclear DNA content of approx. 3·6 pg/2C.

    Full Text Available Agustín de Betancourt y Molina was one of the most distinguished engineers of the eighteenth and nineteenth centuries with numerous contributions to various fields of engineering, including civil engineering. This research shows the process followed in the documentation of the cultural heritage of that Canary engineer, especially in the geometric documentation of a machine for cutting grass in waterways presented in England in 1795 after three years researching on theory of machines. The baseline information has been recovered from the Canary Orotava Foundation of History of Science who has spent years collecting information about the Project Betancourt, in particular, planimetric information as well as a small report on its operation and description of parts of machine. From this information, we have constructed a three dimensional (3D model using CAD techniques with the use of Solid Edge ST7 parametric software, which has enabled the team to create the 3D model as well as different detail plans and exploded views.

  12. Simulation Opportunity Index, A Simple and Effective Method to Boost the Hydrocarbon Recovery

    KAUST Repository

    Saputra, Wardana

    2016-09-08

    During periods of low oil prices, profitability of field developments drops drastically. To help with this difficulty, a cost-effective method has been proposed to boost the hydrocarbon recovery by optimizing well locations through the Simulated Opportunity Index (SOI). SOI is an intelligent method to identify zones with high potential for production which is empirically calculated from basic rock and fluid properties, and from reservoir pressure as its energy capacity. In order to obtain the best results, the original SOI formula (Molina et al., 2009) was extended to both oil and gas fields. Based on this modified SOI formula, a software program has been developed to locate the best well locations considering multilayer, existing wells, and fault existences. This paper describes how the SOI software helps as a simple, fast, and accurate way to obtain the higher hydrocarbon production than that of trial-error method and previous studies in two different fields located in offshore Indonesia. On one hand, the proposed method could save money by minimizing the required number of wells. On the other hand, it could maximize profit by maximizing recovery.

  13. Society of Pediatric Psychology Diversity Award: Training Underrepresented Minority Students in Psychology

    Improving diversity, particularly among trainees and professionals from underrepresented ethnic minority backgrounds, has been a long-stated goal for the field of Psychology. Research has provided strategies and best practices, such as ensuring cultural sensitivity and relevance in coursework, clinical and research training, promoting a supportive and inclusive climate, providing access to cultural and community opportunities, and increasing insight and cultural competence among professionals (Rogers & Molina, 2006). Despite this, the rates of psychologists from ethnically diverse and underrepresented minority (URM) backgrounds remain low and few published studies have described programmatic efforts to increase diversity within the field. This paper describes the INNOVATIONS training model, which provides community and culturally related research experiences, graduate-school related advising, and mentoring to high school and college students. The paper also examines how the model may support enrollment of URM students in doctoral programs in psychology. Findings indicate that INNOVATIONS supported students’ transition from high school and college to graduate programs (with approximately 75% of students enrolling in Master’s and Doctoral programs). INNOVATIONS also supported students, including those from URM backgrounds, enrolling in doctoral programs (41.7%). Students who were trained in the research assistant track were most likely to enroll in psychology doctoral programs, perhaps as a result of the intensive time and training committed to research and clinical experiences. Data support the importance of research training for URM students pursuing psychology graduate study and the need to ensure cultural relevance of the training. Implications for clinical and pediatric psychology are discussed. PMID:28603680

    Full Text Available In this paper, I contend that the main tropes rehearsed by Édouard Glissant in his Poetics of Relation help us better understand the practices surrounding Caribbean filmmaking. Much of recent Caribbean filmmaking articulates experiences that reflect the need for a “relational” film aesthetics. These experiences fundamentally question the common understanding of “identity” as a timeless, fixed, territorial, and exclusionary, inherited from the colonial legacy and often perpetuated in mainstream film practices. Departing from Glissant’s notions of “relation” and “errancy,” I highlight the constraints of identitary demands contained in keywords such as ‘nation’, ‘race’, ‘gender’. This understanding informs my analyses of representative films by Félix de Rooy, Fernando Pérez, Fránces Negrón Muntaner and Luis Molina Casanova, in order to suggest that Caribbean film criticism better captures the region’s emancipatory potential in light of a relational film aesthetics.

    Only two percent of the territory of Peru consists of arable land. Sixteen million people depend on the production of about three million hectares of land, which means that on the average only 1800 square metres is available per person. It is clear that Peru is one of the poorest countries of the world as far as available arable land is concerned and consequently it will have to drastically increase its agricultural production per unit area or import large quantities of agricultural products to feed its rapidly growing population. Agricultural research on the efficient use of fertilizers is being carried out by the regional experiment station (CRIA), by the National University of Agriculture, La Molina, Lima, dealing with programmes on maize, potatoes, cereals and forage crops, by national universities in the country and by specialized research institutes for tropical agriculture on sugar-cane, cotton, coffee and tea. Isotope and radiation techniques are a particularly effective means of determining the best cultural practices for the efficient use of fertilizers and water, and the Joint FAO/IAEA Division of Atomic Energy in Food and Agriculture has been involved in the organization of field and greenhouse programmes at experiment stations and universities in Peru since 1963

P. nigra showed the highest levels of crude protein (11.33 g/100 g dry matter-DM) and ashes (4.12 g/100 g DM). P. juliflora presented the lowest levels of lipids (0.79 g/100 g DM), crude protein (8.84 g/100 g DM) and dietary fiber (40.15 g/100 g DM), and the highest levels of non reducing sugar (52.51 g/100 g DM) and in vitro protein digestibility (66.45%). Trypsin inhibitors concentration (0.29 to 9.32 UTI/mg DM) was inferior to that of raw soy; P. juliflora presented the higher values. Regarding saponin, hemagglutinin and poliphenol values, the levels found are considered low. As for nitrates, the levels found were higher than those reported for peas and beans, with P. chilensis presenting the highest value (2.92 g NO3(-)/kg DM). The levels of phytate varied from 1.31 a 1.53 g/100 g.

    In 2004 migration and mortality for unknown reasons of the herbivorous Black necked swan (Cygnus melancorhyphus (Molina, 1782)) occurred within the Río Cruces wetland (southern Chile), a Ramsar Site and nature sanctuary. Before 2004, this wetland hosted the largest breeding population of this water bird in the Neotropic Realm. The concurrent decrease in the spatial occurrence of the aquatic plant Egeria densa Planch. 1849 - the main food source of swans - was proposed as a cause for swan migration and mortality. Additionally, post-mortem analyses carried out on swans during 2004 showed diminished body weight, high iron loads and histopathological abnormalities in their livers, suggesting iron storage disease. Various hypotheses were postulated to describe those changes; the most plausible related to variations in water quality after a pulp mill located upstream the wetland started to operate in February 2004. Those changes cascaded throughout the stands of E. densa whose remnants had high iron contents in their tissues. Here we present results of a long-term monitoring program of the wetland components, which show that swan population abundance, body weights and histological liver conditions recovered to pre-disturbance levels in 2012. The recovery of E. densa and iron content in plants throughout the wetland, also returned to pre-disturbance levels in the same 8-year time period. These results show the temporal scale over which resilience and natural restoring processes occur in wetland ecosystems of temperate regions such as southern Chile. Copyright © 2018 Elsevier B.V.

    The branch hospital triage aimed at, as well as exercised by nurses, has evolved to meet their needs to organize and make visible the nurses' duties. However, it is still not properly considered as independent nursing intervention. Evidencing practice triage nurse in hospital as experienced by their protagonists disclosed the possible causes of this paradoxical competence. In a sample of 41 nurses, of the 52 possible with previous experience in hospital triage in the Emergency Department of the Hospital General Dr. José Molina Orosa in Lanzarote, the nurses themselves carried out an opinion survey that group together statements about different aspects of the triaje nurse. In its results, 65.8% of those polled thought the triaje nursing training to be deficient and even though nearly half 48.7%, was considered competent to decide the level of emergency, 46.3% disagreed to take this task part of their duty. It is conclusive that the training received in hospital triage, regulated and sustained, is deficient, that is the main reason why professionals have their doubts to take on an activity they are not familiar with. Triage systems do not record the entire outcome of the nursing work and nursing methodology does not seem to be quite indicative for this task.

The health team must consider multiple situations, where the neonate is at risk of having an adverse effect. One of the main interventions that health professionals must practice when interacting with hospitalized newborns is skin care. Neonates often suffer from diaper rash or intravenous drugs extravasation. Recently, hospitalized neonates and especially those in an unstable clinical situation are also at a risk of developing pressure ulcers. The presence of a pressure ulcer in a neonate can lead to serious problems to survival (eg, sepsis, clinical instability. This is the reason why, with this literature review, we attempt to answer questions from health professionals caring for neonates about the prevention and treatment of pressure ulcers.

  1. The influence of Darwinism on racial concepts in Mexico

    2017-06-01

    Full Text Available It has been repeatedly pointed out that Vicente Riva Palacio and Andrés Molina Enríquez were influenced by Darwin’s ideas to develop their own racial concepts regarding the Mexican half-blood. However, after analysing said ideas both in their original biological context as in the social context they were transferred to, it is concluded that this affirmation can only be accepted sensu lato. Their thesis about the superiority of the half-blood is more strongly based on lineal conceptions of evolution and their own alterations than in the Darwinist model of natural selection. It is important to know the influence of Darwinism outside its original context as it helps to understand how the complex and unavoidable exchanges among science, society and politics occurred. Their appropriation of the Darwinist ideas may not be conceptually or methodologically accurate, but it contributed to the ideological construction of the half-blood as an advanced race in terms of evolution. This thesis contrasts with the most prevailing one in other Latin American countries, where the half-bloods were perceived as the personification of a racial degeneration.

    On-site and on-line systems that provide an integrated surveillance of physicochemical and microbiological parameters gain significance in water quality monitoring. Particular relating to diffuse pollution from agricultural areas and use-orientated protection of waters the detection of faecal pollution is a fundamental part. For the near real time and on-site detection of microbiological faecal pollution of water, the beta-D- Glucuronidase (GLUC) enzymatic activity has been suggested as a surrogate parameter. Due to possible short measure intervals of three hours, this method has high potential as a water quality monitoring tool. While cultivation based standard determination takes more than one working day (Cabral 2010) the potential advantage of detecting the GLUC activity is the high temporal measuring resolution. Yet, there is still a big gap of knowledge on the sensitivity and specificity concerning the faecal indication capacity of GLUC in relation to standard assays (Cabral 2010). Interference effects of physicochemical parameters on the enzymatic activity respectively fluorescence have been discussed (Molina-Munoz et al. 2007; Tryland and Fiksdal 1998, Biswal et al. 2003). Results from a monitoring of a rivulet in an agricultural catchment in Lower Austria (HOAL - Hydrological Open Air Laboratory) are presented here. The HOAL offers technical resources that allow measurements at high temporal and spatial resolution and to apply various hydrological methods in one catchment. Two automated enzymatic measuring devices (Coliguard, mbOnline, Austria) and physicochemical in-stream measurements are used, as well as in-stream spectroscopy (spectrolyser, s::can, Austria). Accuracy of both enzymatic measuring devices is compared through diverse hydrological and seasonal conditions. Reference analyses by cultivation based determination were performed. Data from Coliguard devices is combined with physicochemical and spectroscopy data to gain information about the

    The synthesis and correlation of units carried out in the continuous geological map (Roldán et al., 2012), has revealed a fragmentation of the carbonate outcrops belong to the Subbetic Domain (García-Hernández et al., 1980). Subbetic NW verging thrust and fold axial traces have not lateral continuity and Jurassic carbonate outscrops appear as klippes on the olistotromic unit. These ductile structures that can be observed in the internal structure of these jurassic blocks are unrelated to the brittle-ductile deformation bands observed at the basal pelitic levels. Basal detachments are rooted in: a) the Olistostromic unit, a Upper Langhian-Lower Serravallian breccia constituted by gypsum-bearing clay and marls; b) Cretaceous-Tertiary marly sedimentary rocks (Rodríguez-Fernández, et al., 2013) . In both kind of rocks, cataclastic structures allows to infer a top-to-the WSW displacement. Paleostress measurements, made on these detachments levels, are compatible with a extensional regime (Roldán et al., 2012). At the same time, the analysis and interpretation of subsurface data (seismic surveys and borehole testing) shows that the Subbetic Domain (External Subbetic, Molina 1987) are affected by westward low-angle normal faults. A balanced cross-section, based on morphological and cartographic data in the area between Sierra de Cabra and Sierra de Alta Coloma (Valdepeñas de Jaén), shows plurikilometric displacements which has been produced during Late Serravallian-Early Tortonian times.

  15. The Offlap Break Position Vs Sea Level: A Discussion

    Science.gov (United States)

    Tropeano, M.; Pieri, P.; Pomar, L.; Sabato, L.

    Sedimentary lithosomes with subhorizontal topsets, basinward prograding foresets and subhorizontal bottomsets are common in the geologic record, and most of them display similar bedding architectures and/or seismic reflection patterns (i.e. Gylbert- type deltas and shelf wedges). Nevertheless, in shallow marine settings these bodies may form in distinct sedimentary environments and they result from different sed- imentary processes. The offlap break (topset edge) occurs in relation to the posi- tion of baselevel and two main groups of lithosomes can be differentiated with re- spect to the position of the offlap break within the shelf profile. The baselevel of the first group is the sea level (or lake level); the topsets are mainly composed by continental- or very-shallow-water sedimentary facies and the offlap break practi- cally corresponds to the shoreline. Exemples of these lithosomes are high-constructive deltas (river-dominated deltas) and prograding beaches. For the second group, base- level corresponds to the base of wave/tide traction, and their topsets are mostly composed by shoreface/nearshore deposits. Examples of these lithosomes are high- destructive deltas (wave/tide-dominated deltas) and infralittoral prograding wedges (i.e Hernandez-Molina et al., 2000). The offlap break corresponds to the shelf edge (shoreface edge), which is located at the transition between nearshore and offshore set- tings, where a terrace prodelta- or transition-slope may develop (Pomar &Tropeano, 2001). Two main problems derive from these alternative interpretations of shallow- marine seaward prograding lithosomes: 1) both in ancient sedimentary shallow-marine successios (showing seaward prograding foresets) and in high resolution seismic pro- files (showing shelf wedges), the offlap break is commonly considered to correspond to the sea-level (shoreline) and used to inferr paleo sea-level positions and to construct sea-level curves. Without a good facies control, this use of

    Objective To assess the prevalence and risk factors of erectile dysfunction (ED) in HIV patients from the HIV clinic of a tertiary referral center in Mexico City. Design Prevalence was obtained from cross-sectional studies, and the International Index of Erectile Function (IIEF), a standardized method, was used to assess ED. Methods A cross-sectional study was performed in the HIV clinic. Participants completed the IIEF to allow ED assessment. Information on demographics, clinical and HIV-related variables was retrieved from their medical records. Results One hundred and nine patients were included, with a mean age of 39.9 ± 8.8 years. ED was present in 65.1% of the individuals. Patients had been diagnosed with HIV for a mean of 92.7 ± 70.3 months and had undergone a mean 56.4 ± 45.5 months of HAART. The only variable associated with ED in the univariate analysis was dyslipidemia, and this association was also found in the multivariate analysis (P = 0.01). Conclusions ED is highly prevalent in HIV patients. Dyslipidemia should be considered as a risk factor for ED in HIV patients.

    The increased potential for variability of groundwater quality in the South Coast aquifer of Puerto Rico due to saline water encroachment from the Caribbean Sea and from deep parts of the aquifer has become a major concern of water planners and managers. In an effort to determine the extent and sources of this encroachment, the U.S. Geological Survey (USGS) and the Puerto Rico Department of Natural and Environmental Resources conducted a synoptic groundwater-quality survey from April 2 through May 30, 2007, for the South Coast aquifer between Ponce and Arroyo (fig. 1). Groundwater resources in this aquifer extend 150 square miles in south-central Puerto Rico and provide an estimated 44.2 million gallons per day (Mgal/d) or about 61 percent of the total water needs. This amount includes: 15.3 Mgal/d for irrigation, 27.4 Mgal/d for public supply, and 1.5 Mgal/d for industrial and other uses (W.L. Molina-Rivera, U.S. Geological Survey, written commun., 2007). Since 1980 when most of the south coastal plain was intensively cultivated for sugarcane, total groundwater withdrawals have declined about 32 Mgal/d with the greatest decline occurring in irrigation (37.2 Mgal/d) and the greatest increase occurring in public supply (5.5 Mgal/d). Although withdrawals have declined substantially, a major concern is that aquifer recharge provided by irrigation return flow from surface-water irrigation canals has essentially dropped to zero because of the large-scale implementation of groundwater drip irrigation systems.

    Full Text Available Anxiety is characterized by attentional biases to threat, but findings are inconsistent for depression. To address this inconsistency, the present study systematically assessed the role of co-occurring anxiety in attentional bias in depression. In addition, the role of emotional valence, arousal, and gender was explored. Ninety-two nonpatients completed the Penn State Worry Questionnaire (PSWQ; Meyer et al., 1990; Molina & Borkovec, 1994 and portions of the Mood and Anxiety Symptom Questionnaire (MASQ; Watson, Clark, et al., 1995; Watson, Weber, et al., 1995. Individuals reporting high levels of depression and low levels of anxiety (depression only, high levels of depression and anxiety (combined, or low levels of both (control completed an emotion-word Stroop task during event-related brain potential (ERP recording. Pleasant and unpleasant words were matched on emotional arousal level. An attentional bias was not evident in the depression-only group. Women in the combined group had larger N200 amplitude for pleasant than unpleasant stimuli, and the combined group as a whole had larger right-lateralized P300 amplitude for pleasant than unpleasant stimuli, consistent with an early and later attentional bias that is specific to unpleasant valence in the combined group. Men in the control group had larger N200 amplitude for pleasant than unpleasant stimuli, consistent with an early attentional bias that is specific to pleasant valence. The present study indicates that the nature and time course of attention prompted by emotional valence and not arousal differentiates depression with and without anxiety, with some evidence of gender moderating early effects. Overall, results suggest that co-occurring anxiety is more important than previously acknowledged in demonstrating evidence of attentional biases in depression.

    Full Text Available RESUMO: A presente investigação questiona a essência teo-lógica dos futuros contingentes. Para o efeito, analisa-se, primeiramente, a argumentação segundo a qual, sob certas condições lógicas, teológicas, ontológicas e cosmológicas antinecessitantes, detetadas por G. W. Leibniz (conciliando a posição de St. Agostinho com a de L. Molina e W. Ockham, a abertura contingente do futuro parece ser compatível com o regime das "verdades contingentes pré-determinadas", regime enquadrado teologicamente pelo princípio do "futuro melhor" ou do "único futuro verdadeiro". No entanto, os futuros contingentes incitam, com e contra Aristóteles, ao desenvolvimento de uma lógica temporal e plurivalente, ao modo de J. Łukasiewicz ou A. Prior. Essa lógica garante a abertura do futuro sem o oneroso custo metafísico da adesão a uma teo-lógica omnideterminante. A crítica do determinismo lógico, daí resultante, afigura-se mais coadunável com as condições pós-metafísicas inerentes à episteme agnósticacontemporânea, mas, nesse caso, a abertura do futuro implicaria uma profunda redefinição das próprias ideias e funções de "Deus", "matéria", "história" e "verdade".

    This study establishes an altiudinal gradient, spanning from the highland Andes (2400 m) to lowland Amazon, as a productive region for the study of bird pollination in Southeastern Peru. The 'Manú Gradient' has a rich history of ornithological research, the published data and resources from which lay the groundwork for analyses of plant-bird interactions. In this preliminary expedition we documented 44 plants exhibting aspects of the bird pollination syndrome, and made field observations of hummingbird visits at three sites spanning the Manú Gradient: 2800 m (Wayqecha), 1400 m (San Pedro), and 400 m (Pantiacolla). Some of the documented plant taxa are underrepresented in the bird pollination literature and could be promising avenues for future analyses of their pollination biology. The Manú Gradient is currently the focus of a concerted, international effort to describe and study the birds in the region; we propose that this region of Southeastern Peru is a productive and perhaps underestimated system to gain insight into the ecology and evolution of bird pollination. Observations were made on 11, 19, and 14 putatively bird pollinated plant species found at the high-, mid- and low-elevation sites along the gradient, respectively. Hummingbirds visited 18 of these plant species, with some plant species being visited by multiple hummingbird species or the same hummingbird species on differing occasions. Morphometric data is presented for putatively bird-pollinated plants, along with bill measurements from hummingbirds captured at each of three sites. Voucher specimens from this study are deposited in the herbaria of the Universidad Nacional de Agraria de La Molina (MOL), Peru and the University of British Columbia (UBC), Canada. The specimens collected represent a 'snapshot' of the diversity of bird-pollinated flora as observed over 10 day sampling windows (per site) during the breeding season for hummingbirds of Manú .

The artistic action –like any transforming attitude–, seeks to go beyond the law and is conditioned by the need to open it a place to the possible; and try to change the reality, in part to participate in the historical development or for the simple pleasure of the invention, as suggested Escovar W.

One of the most artistic expressions which have been exploited the potential of expression of the body are the performances. Technological and media developments of sixties nurtured these artistic practices, giving rise to which they were designated video performances and video art. The technical reproducibility helped save these performances works of the immediacy of the moment, and then reproduced in other places, in other times, toward thousands of spectators, expanding the possibilities of movement and reception of his metaphors. This is intensified with the advent of the Internet and social networks.

    Full Text Available In order to evaluate the environmental effect on plant development and mini-tuber production of a diverse group of potato genotypes grown under an aeroponic system, a G × E interaction experiment was carried out in greenhouses located at CIP’s experimental stations in La Molina (Lima and Huancayo (Junín. Five contrasting environments were set-up and evaluated. A combined Analysis of Variance was performed for the variables “days to tuber set”, “days to senescence” and “plant height”. An Additive Main Effects and Multiplicative Interaction (AMMI Analysis was performed for yield variables: mini-tuber “weight” and “number of mini-tubers” per plant. There was a high variation in all the responses to the treatments. “Days to tuber set” was influenced by genetic responses, temperature and greenhouse Photosynthetically Active Radiation intensity. Considerable increases in the length of the vegetative cycle and plant height were recorded for all genotypes, and these were particularly notable in the warmer coastal environments. AMMI analysis showed that yield variables were primarily influenced by the genotypic effect followed by the genotype by environment interaction effect. The Venturana variety (T2 was the best performing genotype with a total average mini-tuber “weight” of 644 g per plant while the Chucmarina variety (T1 performed best for the variable “number of mini-tubers” with an overall average of 60.2 mini-tubers per plant. Both showed stability across different environments for these variables. The advanced clones T3 (395434.1, T5 (397077.16 and T6 (397073.16 showed stability for yield variables, but their performance was below the overall average of the trial. It is recommended that the environment and management should ideally be tailored to the genotype as this will result in significant yield gains.

  6. Compound I formation in artichoke (Cynara scolymus L.) peroxidase is modulated by the equilibrium between pentacoordinated and 6-aquo hexacoordinated forms of the heme and by calcium ions.

    Basic artichoke (Cynara scolymus L.) peroxidase (AKP-C), when purified from the plant, has an unusually intense and sharp Soret absorption peak. The resonance Raman spectrum [López-Molina, D., et al. (2003) J. Inorg. Biochem. 94, 243-254] suggested a mixture of pentacoordinate high-spin (5cHS) and 6-aquo hexacoordinate high-spin (6cHS) ferric heme species. The rate constant (k(1)) of compound I formation with hydrogen peroxide (H(2)O(2)) was also lower than expected. Further stopped-flow studies have shown this reaction to be biphasic: a nonsaturating fast phase and a slow phase with complex H(2)O(2) concentration dependence. Addition of calcium ions (Ca(2+)) changed the absorption spectrum, suggesting the formation of a fully 5cHS species with a k(1) more than 5 orders of magnitude greater than that in the absence of Ca(2+) using the chelator ethylenediaminetetraacetic acid. Ca(2+) titrations gave a dissociation constant for a single Ca(2+) of approximately 20 microM. The circular dichroism spectrum of AKP-C was not significantly altered by Ca(2+), indicating that any structural changes will be minor, but removal of Ca(2+) did suppress the alkaline transition between pH 10 and 11. A kinetic analysis of the reaction of Ca(2+)-free AKP-C with H(2)O(2) supports an equilibrium between a slow-reacting 6cHS form and a more rapidly reacting 5cHS species, the presence of which was confirmed in nonaqueous solution. AKP-C, as purified, is a mixture of Ca(2+)-bound 5cHS, 6-aquo 6cHS, and Ca(2+)-free 5cHS species. The possibility that Ca(2+) concentration could control peroxidase activity in the plant is discussed.

    In 1974, Mario Molina and F. Sherwood Rowland warned that chlorofluorocarbons (CFCs) could destroy the stratospheric ozone layer that protects Earth from harmful ultraviolet radiation. In the decade after scientists documented the buildup and long lifetime of CFCs in the atmosphere; found the proof that CFCs chemically decomposed in the stratosphere and catalyzed the depletion of ozone; quantified the adverse effects; and motivated the public and policymakers to take action. In 1987, 24 nations plus the European Community signed the Montreal Protocol. Today, 25 years after the Montreal Protocol was agreed, every United Nations state is a party (universal ratification of 196 governments); all parties are in compliance with the stringent controls; 98% of almost 100 ozone-depleting chemicals have been phased out worldwide; and the stratospheric ozone layer is on its way to recovery by 2065. A growing coalition of nations supports using the Montreal Protocol to phase down hydrofluorocarbons, which are ozone safe but potent greenhouse gases. Without rigorous science and international consensus, emissions of CFCs and related ozone-depleting substances (ODSs) could have destroyed up to two-thirds of the ozone layer by 2065, increasing the risk of causing millions of cancer cases and the potential loss of half of global agricultural production. Furthermore, because most, ODSs are also greenhouse gases, CFCs and related ODSs could have had the effect of the equivalent of 24-76 gigatons per year of carbon dioxide. This critical review describes the history of the science of stratospheric ozone depletion, summarizes the evolution of control measures and compliance under the Montreal Protocol and national legislation, presents a review of six separate transformations over the last 100 years in refrigeration and air conditioning (A/C) technology, and illustrates government-industry cooperation in continually improving the environmental performance of motor vehicle A/C.

  10. Did poor eyesight influence Goya's late works? Medicine and art history in search for an interpretation of Goya's late paintings.

    2018-04-15

    The aim of this article is to 'determine' the scope of Goya's eyesight difficulties and assess the extent to which those difficulties might explain his style of painting in the last years of his life. We analyse the correspondence and late works of the Aragonese painter Francisco de Goya y Lucientes (1746-1828), who has been admired for his use of colour, his energetic loose brushstrokes, his disregard for details and his bold compositions, as well as for his different artistic styles throughout his life. The evolution of Goya's style of painting in his later works seems to have been the consequence of an eyesight condition, probably age-related cataracts at an advanced stage. The faded dark backgrounds, which become blurred with the silhouette of the person portrayed, could indicate a certain degree of eye strain. This can be traced in all these works, but is especially evident in the unfinished portrait of Pío de Molina (1827-1828), as well as in the portraits of Mariano Goya, the artist's grandson (1827), and Jacques Galos (1826). It has been considered that the late and isolated Goya's sight problems were a belated consequence of his severe illness of 1792. Nevertheless, in our opinion, this is a simplistic explanation and, given the painter's age, it is logical to presume that their cause could be age-related lens opacities. This article argues that medicine may become a subsidiary science to art history, as it can provide empirical evidence of the way painters' illnesses may have a strong impact on their artworks. © 2018 Acta Ophthalmologica Scandinavica Foundation.

    The climate variability and change will have increasing influence on the economic and social development of all countries and regions, such as the Andes in Latin America. The CLIMANDES project (Climate services to support decision-making in the Andean Region) will address these issues in Peru. CLIMANDES supports the WMO Regional Training Centre (RTC) in Lima, which is responsible for the training of specialized human resources in meteorology and climatology in the South American Andes (Module 1). Furthermore, CLIMANDES will provide high-quality climate services to inform policy makers in the Andean region (Module 2). It is coordinated by the World Meteorological Organization (WMO) and constitutes a pilot project under the umbrella of the WMO-led Global Framework for Climate Services (GFCS). The project is funded by the Swiss Agency for Development and Cooperation (SDC) and runs from August 2012 - July 2015. Module 1 focuses on restructuring the curricula of Meteorology at the La Molina Agraria University (UNALM) and applied training of meteorologists of the Peruvian National Service of Meteorology and Hydrology (SENAMHI). In Module 2, the skills will be shared and developed in the production and delivery of high-quality climate products and services tailored to the needs of the decision makers in the pilot regions Cusco and Junín. Such services will benefit numerous sectors including agriculture, education, health, tourism, energy, transport and others. The goals of the modules 1 and 2 will be achieved through the collaboration of the UNALM, SENAMHI and the Federal Office of Meteorology and Climatology MeteoSwiss, with the support of the University of Bern (UNIBE), Meteodat and WMO.

    Full Text Available Preliminary analysis of the situation and prospects of the Lima bean crop (Phaseolus lunatus L. in the Peruvian Coast (Valleys of Ica, Pisco and Casma. The Lima bean, Phaseolus lunatus L., is a crop of regional importance on the Peruvian Coast. Within the framework of a collaborative project between the ""faculté universitaire des Sciences agronomiques'"" in Gembloux and the ""Universidad Nacional Agraria La Molina"" in Lima, we carried out a diagnosis of this speculation in the Ica, Pisco and Casma valleys in order to define the constraints which limit crop yields and to suggest improvements within the reach of the smallholders. To achieve these objectives we carried out a formal survey, centred on the Lima bean crop and smallholder relations with the agro-socio-economical environment, and an informal survey, centred on the studied farm systems. To complete these data we met some key informants belonging to all the sectors in contact with agriculture. This study allowed us to identify five undersystems in the farm systems of the Peruvian Coastal Valleys. These undersystems are: cotton, commercial food crops, self-subsistence food crops, livestock and fruit trees. The Lima bean usually belongs to the commercial food crops undersystem. There are two types of constraints. External constraints affect all the components of the farm system and are mainly: end of State support to agriculture, liberalization of trade and unavailability of credit. Internal constraints directly affect the Lima bean crop. Low income leads to a deficiency in pest control and adequate crop management. The Lima bean is also in competition with other components of the system such as cotton and common beans

  13. INTERNATIONAL TRADE AND UNEXPLAINED GENDER WAGE GAPS: EVIDENCE FOR AGRICULTURAL SECTOR IN BOLIVIA

    2017-01-01

    Full Text Available The present investigation has the objective of showing evidence that there would be a reduction on wage differences between men and women in agriculture if they participate in international trade. The methodology that will be used is based on Molina[Mol10], who used Becker [Bec71] as a knowledge base for his study. This methodology consists on showing that wage difference occurs because of a taste for discrimination. This means that companies are willing to pay a higher salary to men just because they want to. But because international trade brings new competence to the markets, local companies need to be more competitive to survive. Therefore they wouldn’t be able to pay higher wages to men; this would reduce the wage difference by gender. Agriculture shows a different behavior from other sectors due to the strong agricultural subsidies governments give, De la Dehesa[Del03]. Using the Oaxaca-Blinder decomposition an estimate wage can be found for both men and women in tradable and non-tradable sectors of agriculture. At the same time two components will be found, one of them shows the difference produced by factors that affect the productivity of an individual. The second component shows the difference that cannot be explained, this is where discrimination is shown. Once these results are found they will be compared to find out if they are different in tradable and non-tradable sectors. The results that have been found show consistency with Molina’s study for the year 2002. Agriculture shows a behavioral difference from other economic sectors and different from Becker’s idea. As there is no unexplained wage difference by gender between tradable and non-tradable sectors. The results show that the difference is that these two sectors are the same. Thus international trade doesn’t result in a reduction of inequality in agriculture.

There are three problems are discussed in this study, namely (1 types of figurative expressions found in the English version of ‘Colours’ magazine and their translation’s equivalence into Indonesian and (2 kinds of translation techniques applied in translating the English figurative expression into Indonesian, This research belongs to qualitative research and the data used in this study were taken from the ‘Colours’ magazine by Garuda Indonesia. The main theory which is applied in this study is taken from the theory of Molina & Albir (2002 in their book entitled Translation Techniques Revisited; A Dynamic and Functionalist Approach. Another theory applied is taken from the theory of McArthur (1992 in his book entitled The Oxford Companion on The English Language. Other supporting theories which are used to support this study are the theory of Larson (1998 in her book entitled Meaning-Based Translation and some other books considered relevant to the topic. The result showed that there are eleven kinds of English figurative expressions found in the data. They are antithesis, euphemism, hyperbole, idioms, irony, metaphor, metonimy, personification, pleonasm, simile and synecdoche. In translating techniques, the translator applied ten translating techniques, they are; adaptation, borrowing, compensation, description, established equivalent, linguistic comprehension, literal technique, modulation, reduction and transposition. In translating a figurative expression from SL into TL, some of the results showed that an English figurative expression is translated into Indonesian figurative translation but some of them can not maintain its figurativeness in Indonesian, therefore the English figurative expression is translated into Indonesian non-figuratively.

    Since 2003, the works of HYBAM observatory (www.ore-hybam.org) has allowed to quantify with accuracy, precision and over a long period Amazon's main rivers discharges and sediments loads. In Peru, a network of 8 stations is regularly gauged and managed in association with the national meteorological and Hydrological service (SENAMHI), the UNALM (National Agrological University of La Molina) and the National Water Agency (ANA). Nevertheless, some current processes of erosion and sedimentation in the foreland basins are still little known, both in volumes and in localization. The sedimentary contributions of Andean tributaries could be there considerable, masking a very strong sedimentation in subsidence zones localized between the control points of the HYBAM's network. The development of spatial techniques such as the Altimetry and reflectance measurement allows us today to complete the ground's network: HYBAM's works have allowed establishing a relation between surface concentration and reflectance in Amazonian rivers (Martinez et al., 2009, Espinoza et al., 2012) and reconstituting water levels series (Calmant et al., 2006, 2008). If the difficulty of calibration of these techniques increases towards the upstream, their use can allow a first characterization of the tributaries contributions and sedimentation zones. At world level, erosion and sedimentation yields in the upper Ucayali are exceptional, favored by a marked seasonality in this region (Espinoza et al., 2009, Lavado, 2010, Pépin et al., 2010) and the presence of cells of extreme precipitation ("Hotspots") (Johnson et al., 1976, Espinoza et al, 2009a). The upper Ucayali drainage basin is a Piggyback where the River run with a low slope, parallel to the Andean range, deposing by gravity hundred millions a year of sands, silts and clays. In this work, we thus propose an estimation of sedimentation and erosion yield in the Ucayali river basin using ground and satellite methods.

The experiments were conducted in commercial greenhouse, with cucumber grafted onto three rootstocks in the first season and onto six rootstocks in the second spring-summer season. The number of leaves was considerably affected by the rootstock in both seasons, and was the highest for the plants grafted onto interspecific rootstocks (28.0 in the first and 44.9 in the second season. The plants grafted onto 'Strong Tosa' had higher total number of fruits (19.9 and yield (5.38 kg compared to other rootstocks or non-grafted plants in first season, and the same result was found for two interspecific rootstocks in the second season (6.96 kg and more than 28.9 fruits per plant. The total soluble solids, pH and electrical conductivity of the fruit were not affected by rootstock, while titratable acidity changed with the rootstock type. The grafting of cucumber plants onto different rootstocks was confirmed as an acceptable non-chemical method to compete with the limitations of soils infected with root-knot nematodes, but the effect was highly dependent on the choice of the rootstock.

Frente a ella, se defiende la concepción de acuerdo con la cual las personas y los fines que ellas persiguen intencionalmente forman parte de los sistemas técnicos mismos, al igual que los conocimientos y creencias que se ponen en juego al operar esos sistemas; y, por tanto, la tecnología ya no puede concebirse como indiferente al bien y al mal. Se analiza, además, el problema que afrontaron los científicos Mario Molina y Sherwood Rowland —Premios Nobel de Química 1995— en sus estudios sobre el agujero de la capa de ozono en la atmósfera terrestre, para ilustrar, por un lado, que es factible actuar de manera responsable en una situación en la que un sistema técnico está produciendo daños, aun cuando no exista evidencia contundente para aceptar una relación causal entre la operación del sistema y los daños en cuestión; y, por otro lado, que hay situaciones en las que los científicos y los tecnólogos tienen responsabilidades morales qua científicos y tecnólogos. El artículo concluye con una revisión de los deberes para los científicos y tecnólogos, para el Estado y las instituciones de educación e investigación, así como para los ciudadanos en general, con respecto a ciertos problemas éticos que plantea la tecnología.

  20. [The examination of men's wits by Juan Huarte de San Juan, and the dawn of the neurobiology of intelligence in the Spanish renaissance].

    The Spanish renaissance doctor Juan Huarte de San Juan (1529-1588) was the author of a unique and immortal work, The Examination of Men's Wits, the edition princeps of which was printed in Baeza in 1575. Since then it has been reprinted at least 80 times and translated into seven languages, which makes it the most influential Spanish contribution to medicine ever published. In this paper we review the unjustly little-known figure of Huarte as the founder of Neuropsychology, and we also analyse his works from a historical and neuroscientific point of view. Huarte's writings deal with the problem of the organic relations between the brain and understanding, and accept the possible influences exerted by temper on the will within the field of the Neurobiology of Intelligence. Thus, over four centuries ago Huarte became the founder of Differential or Physiological Psychology, Neuropsychology, Eugenics and Career Guidance. Huarte's work not only played a fundamental role in the history and development of the body of neuroscientific knowledge, but has also been a clear (although not always cited) influence on scientists, philosophers and men of letters such as Alarcón, Bacon, Cabanis, Cervantes (whose Don Quixote was inspired by him), Charron, Chomsky, Gall, Goethe, Hume, Kant, Kretchmer, Lessing, Lope de Vega, Montaigne, Montesquieu, Nietzsche, Quevedo, Rousseau, Schopenhauer, Thomasius, Tirso de Molina and Ziegler. In the middle of the 16th century, Huarte and his Examination of Men's Wits, together with the works of the naturalist philosophers Gómez Pereira (Antoniana Margarita, 1554) and Miguel Sabuco (New Philosophy, 1587), constituted the prestigious triumvirate of Spanish Renaissance scholars who, for the first time in history, contemplated the workings of the brain from a point of view that had more to do with science than the supernatural.

J Strength Cond Res XX(X): 000-000, 2018-Practical duration stretching after aerobic activities is a recommended component of the first part of warm-up because of its effects on performance. However, its effects on proprioceptive skills are unknown. This study aimed to analyze the effects of running and practical duration static stretching (SS) and dynamic stretching (DS) on postural balance and the joint position sense (JPS) of national sprinters. Thirty-two national sprinters were randomly classified into a SS group (n = 11), DS group (n = 11), or control group (n = 10). Static stretching performed 5 minutes of running and short-duration (20 seconds) static stretches; DS performed 5 minutes of running and short-duration dynamic (20 seconds) stretches; and the control group performed 5 minutes of running. Before and after the intervention, unipedal static postural balance and knee JPS were evaluated. Static stretching exhibited a more centralized center of pressure in the medial-lateral plane for unipedal static postural balance in right-leg support after stretching (p = 0.005, d = 1.24), whereas DS showed values further from the center after stretching for the same unipedal support compared with baseline (p = 0.042, d = 0.49), and the control group remained stable (p > 0.05). Joint position sense did not show significant differences in any group (p > 0.05). In conclusion, combining running and practical duration SS may be beneficial for right-leg postural stabilization, whereas DS may be partly and slightly deleterious. Both SS and DS combined with running and running alone have neutral effects on knee JPS. Sports professionals should consider running and practical duration SS as part of the warm-up of sprinters to partly improve unipedal static postural balance.

    The present study reports field data of ticks infesting wild carnivores captured from July 1998 to September 2004 in Brazil. Additional data were obtained from one tick collection and from previous published data of ticks on carnivores in Brazil. During field work, a total of 3437 ticks were collected from 89 Cerdocyon thous (crab-eating fox), 58 Chrysocyon brachyurus (maned wolf), 30 Puma concolor (puma), 26 Panthera onca (jaguar), 12 Procyon cancrivorus (crab-eating raccoon), 4 Speothos venaticus (bush dog), 6 Pseudalopex vetulus (hoary fox), 6 Nasua nasua (coati), 6 Leopardus pardalis (ocelot), 2 Leopardus tigrinus (oncilla), 1 Leopardus wiedii (margay), 1 Herpailurus yagouaroundi (jaguarundi), 1 Oncifelis colocolo (pampas cat), 1 Eira barbara (tayara), 1 Galictis vittata (grison), 1 Lontra longicaudis (neotropical otter), and 1 Potus flavus (kinkajou). Data obtained from the Acari Collection IBSP included a total of 381 tick specimens collected on 13 C. thous, 8 C. brachyurus, 3 P. concolor, 10 P. onca, 3 P. cancrivorus, 4 N. nasua, 1 L. pardalis, 1 L. wiedii, 4 H. yagouaroundi, 1 Galictis cuja (lesser grison), and 1 L. longicaudis. The only tick-infested carnivore species previously reported in Brazil, for which we do not present any field data are Pseudalopex gymnocercus (pampas fox), Conepatus chinga (Molina's hog-nosed skunk), and Conepatus semistriatus (striped hog-nosed skunk).

Here, we present a case of an EML4-ALK-positive patient with an atypical in-frame insertion from the LTBP1 gene in the canonical junction of variant 1. The patient was a 39-year-old never-smoker female diagnosed with Stage IV lung adenocarcinoma. A core biopsy was negative for EGFR and KRAS mutations but positive for ALK immunohistochemistry and fluorescence in situ hybridization. When submitted to nCounter, the sample showed a 3'/5' imbalance indicative of an ALK rearrangement, but failed to give a positive signal for any of the variants tested. Finally, a band with a molecular weight higher than expected appeared after reverse transcriptase-polymerase chain reaction analysis. When Sanger sequencing was performed, the band revealed an atypical EML4-ALK fusion gene with an in-frame 129 bp insertion. A 115 bp segment of the insertion corresponded to an intronic region of LTBP1, a gene located in the short arm of chromosome 2, between ALK and EML4. The patient received crizotinib and showed a good therapeutic response that is still ongoing after 12 months. Our result suggests that short in-frame insertions of other genes in the EML4-ALK junction do not affect the sensitivity of the EML4-ALK fusion protein to crizotinib.

  9. Solid-State Chemistry as a Formation Mechanism for C 4N 2 Ice and Possibly the Haystack (220 cm -1 ice emission feature) in Titan's Stratosphere as Observed by Cassini CIRS

    A profusion of organic ices containing hydrocarbons, nitriles, and combinations of their mixtures comprise Titan's complex stratospheric cloud systems, and are typically formed via vapor condensation. These ice particles are then distributed throughout the mid-to-lower stratosphere, with an increased abundance near the winter poles (see Anderson et al., 2016). The cold temperatures and the associated strong circumpolar winds that isolate polar air act in much the same way as on Earth, giving rise to compositional anomalies and stratospheric clouds that provide heterogeneous chemistry sites.Titan's C4N2 ice emission feature at 478 cm-1 and "the Haystack," a strong unidentified stratospheric ice emission feature centered at 220 cm-1, share a common characteristic. Even though both are distinctive ice emission features evident in Cassini Composite InfraRed (CIRS) far-IR spectra, no associated vapor emission features can be found in Titan's atmosphere. Without a vapor phase, solid-state chemistry provides an alternate mechanism beside vapor condensation for producing these observed stratospheric ices.Anderson et al., (2016) postulated that C4N2 ice formed in Titan's stratosphere via the solid-state photochemical reaction HCN + HC3N → C4N2 + H2 can occur within extant HCN-HC3N composite ice particles. Such a reaction, and potentially similar reactions that may produce the Haystack ice, are specific examples of solid-state chemistry in solar system atmospheres. This is in addition to the reaction HCl + ClONO2 → HNO3 + Cl2, which is known to produce HNO3 coatings on terrestrial water ice particles, a byproduct of the catalytic chlorine chemistry that produces ozone holes in Earth's polar stratosphere (see for example, Molina et al., 1987 Soloman, 1999).A combination of radiative transfer modeling of CIRS far-IR spectra, coupled with optical constants derived from thin film transmittance spectra of organic ice mixtures obtained in our Spectroscopy for Planetary ICes

    Full Text Available A finales de 1823, la Sala de Representantes de San Miguel de Tucumán, dispuso la aprobación del decreto de pena de muerte para el gobernador Bernabé Aráoz, exiliado en la vecina ciudad de Salta. El entonces presidente de la Sala, el Presbítero José Manuel Moure, acudió a la formación de una comisión de eclesiásticos integrada por Diego León Villafañe (Jesuita, Pedro Miguel Aráoz y José Agustín Molina, para que se expresaran sobre el tema. Es a partir de este caso particular que nos preguntamos a cerca de la discusión sobre la pena de muerte, tanto en ámbito laico como eclesiástico; y de que manera este acontecimiento nos revela algunos rasgos de la relación entre “lo político” y lo religioso después de la revolución. Nos interesa indagar sobre las herramientas teóricas y jurídicas con las que se contaba en la época, para promulgarse sobre la materia. Abordar la decisión de la aplicación de la pena de muerte –en este caso a Bernabé Aráoz- desde un aspecto político jurídico eclesiástico, partiendo del hecho de que es una comisión eclesiástica la que finalmente avala la decisión. El clero fue uno de los actores fundamentales dentro del entramado social colonial. Este rol principal sufrió algunas modificaciones a partir de mayo de 1810, cuando la revolución empezó a delinear una nueva forma de relación entre la Iglesia y los individuos que la componían, y los nuevos poderes emergentes. La revolución y los nuevos gobiernos comenzaron a apropiarse de espacios específicos del clero, como el púlpito, al tiempo que éstos participaban de espacios políticos cada vez más “públicos”.

  12. Crisis de la ciencia, crisis del escepticismo ético

    Full Text Available La mecánica de Newton ha sido considerada el único método científico posible desde el siglo XVII hasta entrado el siglo XX. Este modelo físico consideró que era preciso introducir severas restricciones epistemológicas en el método científico, y declaró que solamente eran relevantes para la ciencia los "cuerpos regulares", es decir, los aspectos de los objetos que podían ser tratados según números y figuras, y esto implicaba que las ciencias propiamente humanas habían de quedar al margen de la ciencia. En consecuencia, la justicia -y con ella toda la moral- quedó condenada al campo de reclusión de los sentimientos utópicos, sin que pudiera mostrar algún título que le permitiera recabar un estatus también "real". El autor alude a la manera como la mecánica newtoniana ha sido desposeída de su título de ciencia paradigmática de toda indagación científica desde comienzos del siglo XX. En lo que concierne a la moral social, el resultado más inmediato de esta crisis de lo que ahora es llamado mecánica "clásica", es que se han mostrado sin sentido las viejas restricciones puestas en virtud del método, de modo que si es científico comprobar que el agua se descompone a los cien grados centígrados, no menos objetivo es asegurar que el profesor tiene el deber real de explicar con la claridad suficiente. Ahora podemos volver a tomar en serio, en sede propiamente científica, las vertientes ontológicas de los razonamientos jurídicos. Hablar de ontología no implica volver a la metafísica que propusieron Gabriel Vázquez de Belmonte y Luis de Molina, y que algunos extienden también a Francisco Suárez. Es más bien el momento de volver a reconsiderar las propuestas científicas de Tomás de Aquino sin caer en la tentación de filtrar la doctrina del de Aquino por las explicaciones de estos otros escolásticos tardíos.

Lugar: Programa de Post Grado en Nutrición Pública, Universidad Nacional Agraria La Molina, y Departamento de Estadística e Informática. Material y Métodos: Se analizó las bases de datos nacionales de las Encuestas Demográficas y de Salud Familiar (Endes, de los años 1991/1992, 1996 y 2000. Principales medidas de resultados: Desnutrición en niños menores de 5 años. Resultados: Durante el período evaluado, la desnutrición crónica disminuyó de 39% a 32%, la desnutrición global de 12% a 9% y la desnutrición aguda de 2% a 1%. Mientras tanto, el sobrepeso y la obesidad ascendieron de 17% y 5% a 19% y 7%, respectivamente. La Endes 2000 muestra un promedio nacional de sobrepeso y obesidad en niños menores de cinco años de 25,19%, siendo los mas afectados Tacna (57%, Moquegua (42% y Lima (41%; niños de 48 a 59 meses, extremadamente pobres y del área urbana. Según las proyecciones departamentales, Tumbes y Ucayali, a partir del año 2004, sobrepasarían el 50% de sobrepeso. Las variables más influyentes para el desencadenamiento del problema son el nivel de pobreza, la edad del niño y el área de residencia, descartándose el género, la instrucción de la madre y el departamento de proveniencia, como variables significativas. Conclusiones: Aunque persiste el problema de desnutrición en los niños peruanos, el sobrepeso y la obesidad vienen alcanzando valores considerablemente elevados, con proyecciones que van en rápido incremento.

  17. Assessing the reduction of the hydrological connectivity of gully systems through vegetation restoration: field experiments and numerical modelling

    Full Text Available Restoration of degraded land in the Southern Ecuadorian Andes has led to alterations in the functioning of degraded catchments. Recovery of vegetation on areas affected by overgrazing, as well as the reforestation or afforestation of gully areas have given rise to modifications of hydrological connectivity within the catchments. Recent research has highlighted the ability of gully channels to trap sediment eroded from steep slopes, especially if vegetation is established along the gully bed. However, vegetation cover not only induces sediment deposition in the gully bed, but may also have a potential to reduce runoff water volume. The performance of gully beds in reducing the transfer of runoff was investigated by conducting controlled concentrated flow experiments in the field. Experimental field data for nine gullies were derived by pouring concentrated inflow into the upstream end and measuring the outflow at the downstream end of the channel. Two consecutive flow experiments per gully were carried out, so that data for dry and wet soil conditions were collected. The hydrological response to concentrated flow was estimated for each experiment by calculating its cumulative infiltration coefficient, IC (%. The results showed a great difference in IC between dry and wet soil conditions. The IC for wet soil conditions was on average 24%, whereas it was 60% for dry conditions. Gullies with more than 50% surface vegetation cover exhibit the highest cumulative infiltration coefficients (81% for dry runs, and 34% for wet runs, but runoff transmission losses were not as clearly related to vegetation cover as sediment storage as shown in Molina et al. (2009. The experimental field data of 16 experiments were used to calibrate a hydrological model developed by Fiener and Auerswald (2005 in order to simulate the transfer of concentrated flow along the gully beds. The calibrated model was able to simulate the transfer of runoff water

    Although archaeological research suggests that mining/metallurgy already started in the Chalcolithic (3rd millennium BC), the earliest atmospheric metal pollution in SW Europe has thus far been dated to ~ 3500–3200 cal. yr. BP in paleo-environmental archives. A low intensity, non-extensive mining/metallurgy and the lack of appropriately located archives may be responsible for this mismatch. We have analysed the older section (> 2100 cal. yr. BP) of a peat record from La Molina (Asturias, Spain), a mire located in the proximity (35–100 km) of mines which were exploited in the Chalcolithic/Bronze Age, with the aim of assessing evidence of this early mining/metallurgy. Analyses included the determination of C as a proxy for organic matter content, lithogenic elements (Si, Al, Ti) as markers of mineral matter, and trace metals (Cr, Cu, Zn, Pb) and stable Pb isotopes as tracers of atmospheric metal pollution. From ~ 8000 to ~ 4980 cal. yr. BP the Pb composition is similar to that of the underlying sediments (Pb 15 ± 4 μg g{sup −1}; {sup 206}Pb/{sup 207}Pb 1.204 ± 0.002). A sustained period of low {sup 206}Pb/{sup 207}Pb ratios occurred from ~ 4980 to ~ 2470 cal. yr. BP, which can be divided into four phases: Chalcolithic (~ 4980–3700 cal. yr. BP), {sup 206}Pb/{sup 207}Pb ratios decline to 1.175 and Pb/Al ratios increase; Early Bronze Age (~ 3700–3500 cal. yr. BP), {sup 206}Pb/{sup 207}Pb increase to 1.192 and metal/Al ratios remain stable; Late Bronze Age (~ 3500–2800 cal. yr. BP), {sup 206}Pb/{sup 207}Pb decline to their lowest values (1.167) while Pb/Al and Zn/Al increase; and Early Iron Age (~ 2800–2470 cal. yr. BP), {sup 206}Pb/{sup 207}Pb increase to 1.186, most metal/Al ratios decrease but Zn/Al shows a peak. At the beginning of the Late Iron Age, {sup 206}Pb/{sup 207}Pb ratios and metal enrichments show a rapid return to pre-anthropogenic values. These results provide evidence of regional/local atmospheric metal pollution triggered by the

    A method of large-scale breeding of Dysdercus peruvianus G. (family Pyrrhocoridae) with natural food and giving a hundred-fold population increase each month has been developed in the Entomology Laboratories of the Experimental Agricultural Station at La Molina, Lima, Peru. Cages 90 x 60 x 60 cm are used; 2000 adults are placed in each, care being taken that there are not more males than females (two males to each three females are sufficient). The cage floor consists of wire mesh with nine strands per square inch; the roof, made of cloth or mesh with 14-18 strands per square inch, is fitted with a 15-W fluorescent light or a 60-W incandescent light, and the walls are of wood or some other washable material. Inside the cages are placed two containers with levant cotton shoots, and about 500 g of seed are scattered on the floor. Under the mesh is a sloping floor of plexiglas or some other smooth material which allows the eggs to slide down to a collecting channel ending in a tube marked in centimetres (1 cm 3 = 4250 eggs). Similar cages, but with a wooden or brass floor, are used to contain ½ cm 3 of eggs, which are scattered on the floor covered with levant cotton seed. The eggs hatch and the nymphs grow in this cage until they reach the adult stage, when they are taken out in batches of 2000 and transferred to tanks for adults or irradiated. Doses of 1000, 2500, 5000 and 10 000 R were used, and sterility was obtained from 2500 R, at which dose eggs were produced and development occurred to the first nymph stage. At 5000 and 10 000 R the eggs did not develop. At 1000 R development was normal, and in addition the cycle was accelerated and there were more eggs. Irradiated males and females accepted, and were accepted by, normal insects without discrimination. Competence levels of 2, 8, 32 and 128 males were tested. (author) [es

    In the last years researchers reported an increasing need to have more awareness on the intimate link between land use and soil hydrological properties (soil organic matter storage, water infiltration, hydraulic conductivity) and their possible effects on water retention (e.g., Bens et al., 2006; del Campo et al., 2014; González-Sanchis et al., 2015; Molina and del Campo, 2012). In the Mediterranean ecosystems, special attention needs to be paid to the forest-water relationships due to the natural scarcity of water. Adaptive forest management (AFM) aims to adapt the forest to water availability by means of an artificial regulation of the forest structure and density in order to promote tree and stand resilience through enhancing soil water availability (del Campo et al., 2014). The opening of the canopy, due to the removal of a certain number of trees, is an important practice for the management of forests. It results in important modifications to the microclimatic conditions that influence the ecophysiological functioning of trees (Aussenac and Granier, 1988). However, the effect of thinning may vary depending on the specific conditions of the forest (Andréassian, 2004; Brooks et al., 2003; Cosandey et al., 2005; Lewis et al., 2000; Molina and del Campo, 2012). Different authors reported that a reduction in forest cover increases water yield due to the subsequent reduction in evapotranspiration (Brooks et al., 2003; González-Sanchis et al., 2015; Hibbert, 1983; Zhang et al., 2001). On the other hand, the water increase may be easily evaporated from the soil surface (Andréassian, 2004). In this context, determining soil hydraulic properties in forests is essential for understanding and simulating the hydrological processes (Alagna et al., 2015; Assouline and Mualem, 2002), in order to adapt a water-saving management to a specific case, or to study the effects of a particular management practice. However, it must be borne in mind that changes brought about by

    Cooling machine technologies really affect nowadays’ modern life, not only limited in enhancement of life quality and comfort, but it has also reached the essential things of humans’ life supporter (Arora, 2001). Cooling machine technologies have direct contribution toward environmental damage such as depletion of ozone layer and global warming through synthetic refrigerant waste and leakage (CFC and HFC) to environment. The refrigerant release to the environment is 60% of the service sector. Destructive characteristics of ozone possessed by CFC were first proposed by Rowland and Molina which were then supported by yard measurement. It is estimated that ozone layer damage occurs for about 3% every decade. The ozone layer located in the stratosphere is functioned to prevent ultraviolet-B ray from entering into earth surface. This Ultraviolet-B is suspected to be the cause of health problem for humans and disorder for plants on earth. As for the purpose of this research is to obtain a product design of refrigerant waste processing system (recovery and recycle refrigerant) as well as to acknowledge the work method (COP) of cooling machines that use CFC refrigerant (R-12) as the result of recovery and recycle compared to CFC refrigerant (R-12)/pure R134a. One method that can be used is by redesigning existing equipment namely 3R machine that cannot be used anymore thus it can be reused. This research will be conducted through modifying the existing 3R machine therefore it can be reused and be easily operated as well as doing the maintenance, after that the refrigerant as the result of recovery will be tried on a refrigeration system and a test of refrigeration system work method will be conducted by using the refrigerant recycle product which is obtained and compared with the work method of the one with pure refrigeration.The result has been achieved that the redesign product of refrigerant waste processing equipment can be reused and able to perform the recovery

    The Andes mountain range provides the setting for watersheds with high natural background of metals and for mining operations that enhance contaminant mobilization, notably in Northern and Central Chile. Dissolved and solid metal species are actively transported by streams to the Pacific Ocean from area and point sources, like acid drainage. We examine the response of metal rich particle suspensions downstream zones of mixing where shifts in the chemical environment occur. We propose a conceptual model which is used to analyze the fate of copper in the upper Mapocho watershed. The main source of copper is the Yerba Loca river, a naturally impacted stream with pH ranging from 3 to 7 and high concentrations of Cu (0.8 - 6.3 mg/L), Al (1.3 - 7.6 mg/L) and Fe (0.4 - 4.2 mg/L). Steep chemical shifts occur after the confluences with the San Francisco and the Molina rivers. We characterized stream chemistry, hydrological variables and suspended particles, including particle size distribution (PSD), turbidity, and total suspended solids. A marked seasonal behavior was observed, with a higher total Cu flux during smelting periods and a shift towards the dissolved phase during summer. When acid drainage is discharged into a receiving stream, incomplete mixing occurs thereby promoting the formation of a range of metal-rich solids with a characteristic PSD. Similarly, areas of chemical heterogeneity control the partition of metals associated to suspended geomaterials coming from bank and slope erosion. A highly dynamic process ensues where metastable phases shift to new equilibria as fully mixed conditions are reached. Depending on the reaction kinetics, some particles persist despite being exposed to thermodynamically unfavorable chemical environments. The persistence of metal-rich particles downstream zones of acid drainage mixing is important because it ultimately controls the flux of metals being delivered to the ocean by watersheds impacted by acid drainage.

    Rapid loss estimation after potentially damaging earthquakes is critical for effective emergency response and public information. A methodology and software package, ELER-Earthquake Loss Estimation Routine, for rapid estimation of earthquake shaking and losses throughout the Euro-Mediterranean region was developed under the Joint Research Activity-3 (JRA3) of the EC FP6 Project entitled "Network of Research Infrastructures for European Seismology-NERIES". Recently, a new version (v2.0) of ELER software has been released. The multi-level methodology developed is capable of incorporating regional variability and uncertainty originating from ground motion predictions, fault finiteness, site modifications, inventory of physical and social elements subjected to earthquake hazard and the associated vulnerability relationships. Although primarily intended for quasi real-time estimation of earthquake shaking and losses, the routine is also equally capable of incorporating scenario-based earthquake loss assessments. This paper introduces the urban earthquake loss assessment module (Level 2) of the ELER software which makes use of the most detailed inventory databases of physical and social elements at risk in combination with the analytical vulnerability relationships and building damage-related casualty vulnerability models for the estimation of building damage and casualty distributions, respectively. Spectral capacity-based loss assessment methodology and its vital components are presented. The analysis methods of the Level 2 module, i.e. Capacity Spectrum Method (ATC-40, 1996), Modified Acceleration-Displacement Response Spectrum Method (FEMA 440, 2005), Reduction Factor Method (Fajfar, 2000) and Coefficient Method (ASCE 41-06, 2006), are applied to the selected building types for validation and verification purposes. The damage estimates are compared to the results obtained from the other studies available in the literature, i.e. SELENA v4.0 (Molina et al., 2008) and

Resultados: Muestra compuesta por  diadas, el 88% de los cuidadores eran mujeres, edad media de 52± 16 años, dedicaban 24 horas al cuidado. El 100% de receptores de cuidado eran dependientes del cuidador. Las intervenciones, disminuyeron la sobrecarga percibida por los cuidadores. Discusión: El cuidado de enfermería brindado en otros espacios extra hospitalarios y centrados en personas no enfermas,  contribuye a disminuir la  sobrecarga requiriendo del apoyo permanente del profesional de enfermería. Conclusiones: Se evidenció  la disminución de la sobrecarga de  cuidadores y el aumento del grado de funcionalidad de las familias  al medirlos después de realizar las intervenciones identificación rol de cuidador, autocuidado, estrategias para brindar cuidado con calidad, manejo de conflictos intrafamiliares, comunicación, relajación y habilidades de cuidado.

    Full Text Available Motivar la incorporación de la perspectiva de género dentro de la investigación criminológica que se hace en Ecuador es el objetivo de este trabajo que se realiza a partir de la definición de Antonio García-Pablos de Molina sobre Criminología y la concreción de Tania Patricia Ibáñez Gómez. Gracias a la concepción de género que aporta el Comité para la Eliminación de la Discriminación Contra la Mujer - CEDAW y el marco jurídico constitucional ecuatoriano se hace una aproximación de análisis de las estadísticas de la población por sexos y de las personas privadas de la libertad. Al transitar por argumentos científicos de algunas escuelas criminológicas para abordar el régimen penitenciario, la mujer víctima, género y política criminal, control social y el delito como objeto de la Criminología se demuestra la feminización de la pobreza basada en el salario que percibe y sus horas laborables como resultado de la condición socioeconómica lo que posibilita un perfil criminológico de las mujeres privadas de la libertad con contenido socio biológico. En el camino de esta investigación y desde un enfoque estadístico se encontró los indicadores de: la casi igualdad cuantitativa de la población por sexos. La desigualdad de horas de trabajo y salarios entre varones y mujeres y la escasa participación de las mujeres en la delincuencia, dando como resultado el poco interés de la Criminología con visión de género en el contexto económico y no veraz que la ceguera de la Criminología a la perspectiva de género deviene de los datos empíricos.

    Although archaeological research suggests that mining/metallurgy already started in the Chalcolithic (3rd millennium BC), the earliest atmospheric metal pollution in SW Europe has thus far been dated to ~3500-3200 cal.yr. BP in paleo-environmental archives. A low intensity, non-extensive mining/metallurgy and the lack of appropriately located archives may be responsible for this mismatch. We have analysed the older section (>2100 cal.yr. BP) of a peat record from La Molina (Asturias, Spain), a mire located in the proximity (35-100 km) of mines which were exploited in the Chalcolithic/Bronze Age, with the aim of assessing evidence of this early mining/metallurgy. Analyses included the determination of C as a proxy for organic matter content, lithogenic elements (Si, Al, Ti) as markers of mineral matter, and trace metals (Cr, Cu, Zn, Pb) and stable Pb isotopes as tracers of atmospheric metal pollution. From ~8000 to ~4980 cal.yr. BP the Pb composition is similar to that of the underlying sediments (Pb 15 ± 4 μg g(-1); (206)Pb/(207)Pb 1.204 ± 0.002). A sustained period of low (206)Pb/(207)Pb ratios occurred from ~4980 to ~2470 cal.yr. BP, which can be divided into four phases: Chalcolithic (~4980-3700 cal.yr. BP), (206)Pb/(207)Pb ratios decline to 1.175 and Pb/Al ratios increase; Early Bronze Age (~3700-3500 cal.yr. BP), (206)Pb/(207)Pb increase to 1.192 and metal/Al ratios remain stable; Late Bronze Age (~3500-2800 cal.yr. BP), (206)Pb/(207)Pb decline to their lowest values (1.167) while Pb/Al and Zn/Al increase; and Early Iron Age (~2800-2470 cal.yr. BP), (206)Pb/(207)Pb increase to 1.186, most metal/Al ratios decrease but Zn/Al shows a peak. At the beginning of the Late Iron Age, (206)Pb/(207)Pb ratios and metal enrichments show a rapid return to pre-anthropogenic values. These results provide evidence of regional/local atmospheric metal pollution triggered by the earliest phases of mining/metallurgy in the area, and reconcile paleo-environmental and

The aim of this study was to describe the extent and pattern of the involvement of cognitive impairment and psychological status in all patients with multiple sclerosis on a small Spanish island.Patients and methods: In all, 70 patients and 56 healthy controls were included in the study between February 2013 and May 2013. All participants were assessed using the Brief Repeatable Battery of Neuropsychological Test. The patients also completed instruments to evaluate the presence of fatigue, perceived cognitive dysfunction, and symptoms of anxiety and depression. All procedures were performed in a single session.Results: Cognitive impairment, defined as a score <1.5 standard deviation on two subtests of the battery, was present in 35% of the participants. The most frequently affected domain was working memory, followed by verbal memory and processing speed. Disease duration showed a moderate correlation with visuospatial memory and processing speed. The Expanded Disability Status Scale score correlated with verbal and processing speed. Verbal memory was correlated with depression symptoms and fatigue.Conclusion: Cognitive impairment was present in 35% of the study population. The most affected domains were working memory and verbal memory. Working memory and verbal fluency deficit are independent factors of disease evolution. Cognitive decline is related to clinical variables and

Evidence about the effectiveness of neuropsychological rehabilitation is still limited, but current data suggest that computer-assisted cognitive training improves cognitive performance.Objective: The objective of this study was to evaluate the efficacy of combined computer-assisted training supported by home-based neuropsychological training to improve attention, processing speed, memory and executive functions during 3 consecutive months.Methods: In this randomized controlled study blinded for the evaluators, 62 MS patients with clinically stable disease and mild-to-moderate levels of cognitive impairment were randomized to receive a computer-assisted neuropsychological training program (n=30 or no intervention (control group [CG]; n=32. The cognitive assessment included the Brief Repeatable Battery of Neuropsychological Test. Other secondary measures included subjective cognitive impairment, anxiety and depression, fatigue and quality of life measures.Results: The treatment group (TG showed significant improvements in measures of verbal memory, working memory and phonetic fluency after intervention, and repeated measures analysis of covariance revealed a positive effect in most of the functions. The control group (CG did not show changes. The TG showed a significant reduction in anxiety symptoms and significant improvement in quality of life.

    Full Text Available The fact of speaking a language instead of another at a specific moment in a person’s life depends on many and diverse factors such as immigration, the language acquired and spoken at home, and what the dominant and official language is. In addition,in situations where it is possible to choose, speaking one language instead of another is not a neutral choice, in that the values associated with languages have a lot to do with that choice. In the Valencian Community, in Spain, two languages officially coexist: Castilian,the official language within the whole Spanish State, and Catalan,the historical language of the territory, which is undergoing a process of revitalization since the beginnings of the 1980s. At that time,Catalan was perceived as a second-rate language, associated with peasantry, with the rural context and uncultured people from the lower social classes. The technique employed to reveal these values or stereotypes, namely the matched-guise technique (Ros 1984,was used again during the 90s (Blas Arroyo 1995, Gómez Molina1998 for evaluating the effects of the revitalization program. The results of this work showed that Catalan was gaining more and more prestige, i.e., it was increasingly associated with modern people,city life, learning and social progress. An underlying, though never proved, assumption was that the remarkable improvement in the image of Catalan would be reflected in its use, which would also be more frequent and more widespread. At the beginning of the new millennium the matched-guise technique was applied again,with one new twist: to assess the real extent of prestige associated with speaking Catalan (Casesnoves and Sankoff 2003. Ten years later that study was replicated in order to observe the evolution of linguistic attitudes as well as the progress of the linguistic revitalization process. In this presentation, we compare the two data sets to evaluate the effects of linguistic attitudes on the use of Catalan

En este contexto, analizamos la variación en riqueza y composición de la dieta de T. niger en cuatro comunidades intermareales rocosas del norte de Chile, distribuidas en 1.000 km de costa, y muestreadas estacionalmente entre invierno 2004 y primavera 2005. Durante el estudio ocurrió el evento El Niño 2004-2005 cuyo efecto potencial fue incorporado en esta evaluación. En cada comunidad y estación se evaluó la abundancia de las especies presentes en 45 cuadrantes (0,25 m² distribuidos en cinco bloques permanentes, recolectando cerca de 10 individuos de T. niger a los que se midió su biomasa y longitud, determinando el número, identidad y frecuencia de ocurrencia de ítemes en su contenido gástrico. Colectamos un total de 251 individuos de T. niger, que en conjunto consumieron 89 ítemes de algas (64 % e invertebrados (36 %; incluyendo otros herbívoros. Una relación inversa significativa entre el tamaño corporal y el número de ítemes animales ingeridos sugiere que T. niger varía su dieta durante la ontogenia. La amplitud de nicho dietario fue alta y tendió a disminuir hacia latitudes menores. Globalmente, el espectro y frecuencia de ocurrencia de ítemes dietarios no fueron significativamente distintos entre comunidades, pese a marcadas diferencias en intensidad de surgencia entre ellas. Similarmente, no hubo relación clara entre la oferta ambiental de recursos y su frecuencia en la dieta de T. niger, destacando la clorófita Ulva rígida que fue el ítem consumido con más frecuencia en cada comunidad pero no el más abundante en terreno. Sin embargo, la riqueza dietaria de T. niger se relacionó negativa y significativamente con la

Seule la confrontation des différentes versions – Chronique de vingt rois, Version sancienne, Chronique de Castille –, indépendantes les unes des autres mais dépendant toutes de la Version alphonsine primordiale, permet de la reconstituer. On peut ainsi définir le modèle de femme régnante qu’élabore l’historiographe alphonsin à partir des sources latines. Reines, infantes et régentes, de Sancie, femme de Ferdinand Ier, à Bérengère, mère de Ferdinand III, se distinguent par leurs actions pieuses et leurs bons conseils, qu’elles peuvent légitimement prodiguer au roi car elles sont toutes dotées d’une qualité essentielle : le bon entendement. Les écarts entre les différentes versions historiographiques témoignent aussi de l’évolution de ce modèle en fonction du contexte socio-politique de production des textes. Plus radicale, la Chronique de vingt rois, écrite à la fin du règne d’Alphonse X, sanctionne sévèrement les débordements. La Chronique de Castille, écrite sous la minorité de Ferdinand IV, accentue le modèle alphonsin en présentant une lignée de femmes exemplaires dont la régente Marie de Molina est la digne descendante. En outre, les femmes de la Chronique de Castille excellent en un domaine, le spirituel, et veillent ainsi à la préservation et à la pérennité de l’image de la royauté.No existe ningún testimonio manuscrito de la Versión concisa de la Historia de España (1270 para los reinados de Fernando I a Fernando III.

    A method of large-scale breeding of Dysdercus peruvianus G. (family Pyrrhocoridae) with natural food and giving a hundred-fold population increase each month has been developed in the Entomology Laboratories of the Experimental Agricultural Station at La Molina, Lima, Peru. Cages 90 x 60 x 60 cm are used; 2000 adults are placed in each, care being taken that there are not more males than females (two males to each three females are sufficient). The cage floor consists of wire mesh with nine strands per square inch; the roof, made of cloth or mesh with 14-18 strands per square inch, is fitted with a 15-W fluorescent light or a 60-W incandescent light, and the walls are of wood or some other washable material. Inside the cages are placed two containers with levant cotton shoots, and about 500 g of seed are scattered on the floor. Under the mesh is a sloping floor of plexiglas or some other smooth material which allows the eggs to slide down to a collecting channel ending in a tube marked in centimetres (1 cm{sup 3} = 4250 eggs). Similar cages, but with a wooden or brass floor, are used to contain Vulgar-Fraction-One-Half cm{sup 3} of eggs, which are scattered on the floor covered with levant cotton seed. The eggs hatch and the nymphs grow in this cage until they reach the adult stage, when they are taken out in batches of 2000 and transferred to tanks for adults or irradiated. Doses of 1000, 2500, 5000 and 10 000 R were used, and sterility was obtained from 2500 R, at which dose eggs were produced and development occurred to the first nymph stage. At 5000 and 10 000 R the eggs did not develop. At 1000 R development was normal, and in addition the cycle was accelerated and there were more eggs. Irradiated males and females accepted, and were accepted by, normal insects without discrimination. Competence levels of 2, 8, 32 and 128 males were tested.

    La especialidad clínica de la endocrinología lleva ya más de medio siglo en nuestro país, y si nos ponemos a ver la actividad de algunos precursores, esta historia bien puede remontarse al siglo XIX.

    El académico Antonio Ucrós Cuellar se puso en la tarea de recopilar las actuaciones de los especialistas en problemas hormonales y en las actividades de las asociaciones científicas de este ramo de la medicina y para ello contó con la ayuda editorial de los endocrinólogos y discípulos suyos, Eric Hernández y Stella Acosta.

    Ucrós ha participado personalmente en el devenir histórico de la endocrinología en Colombia, como investigador de la problemática del bocio, como fundador de la Asociación Colombiana de Endocrinología y de la sección de endocrinología del Hospital de San José, que recientemente cumplió sus Bodas de Oro, y en la cual se han formado numerosos y distinguidos especialistas que ejercen en el país su profesión.

    Comentar esta obra viene como anillo al dedo en este número especial sobre endocrinología que publica la revista “Medicina” de la Academia. Este libro de 230 páginas recoge en su parte inicial los antecedentes históricos y los estudios sobre el bocio en el país que el autor tan elegantemente lideró, finaliza esta parte inicial con su propia versión de la endocrinología en Colombia, que comienza con él y otros eminentes especialistas como Hernán Mendoza Hoyos, Tomás Quintero, Alonso Gutiérrez, Jaime Cortázar, Efraím tero, Mario Sánchez Medina (en el campo de la diabetes, Iván Molina en Medellín, Alberto Jamis en Barranquilla, y el importante grupo de Cali donde figuraron entre otros Eduardo Gaitán, Heins Wahner (actualmente en la Clínica Mayo, William Jubiz y Matilde de Bernal, todos de talla internacional.

    Mi interés por la endocrinología se inició con las magistrales clases de Mendoza Hoyos en la Javeriana, sobre el tema de la Fisiología Endocrina

We present the performance of these instruments at different waste treatment facilities (waste water treatment plants, composting facilities, sludge mineralization beds, anaerobic digesters and landfills) in Denmark, and discuss the strengths and limitations of the method of the method for quantifying methane and nitrous oxide emissions from the different sources. Furthermore, we have measured the methane emissions from 10 landfills with emission rates ranging from 5 to 135 kg/h depending on the age, state, content and aftercare of the landfill. In addition, we have studied 3 waste water treatment plants, and found nitrous oxide emission of 200 to 700 g/h from the aeration tanks and a total methane emission ranging from 2 to 15 kg/h, with the primary emission coming from the sludge treatment.

    The XVII International Conference on Strings, Particles and Cosmology, PASCOS 2012, was held in the City of Mérida, Mexico, from June 3-8, 2012. The conference series is aimed at exploring the interface and interplay between particle physics, string theory and cosmology. With the advent of new data, the emphasis of the XVIII edition of PASCOS was on phenomenology and the interpretation of recent observational and experimental results. The conference followed the format of previous conferences in this series, with plenary reviews and contributed presentations in parallel sessions. The lectures covered a wide range of subjects which included: Dark matter and dark energy, flavor physics and CP violation, neutrino physics, supersymmetry, Higgs physics, baryogenesis and EDMs, supergravity, high energy cosmic rays, string and F-theory GUTs, and string phenomenology. This is the first time that PASCOS was held in Latin America. The aim to do it in Mexico was to engage the Latin American community and thus to bring the conference to a wider and different audience, a goal which was thoroughly achieved. The venue was held at the Hotel Fiesta Americana in the beautiful city of Mérida. The social events included a reception with typical local food at the Katun restaurant, conference dinner at the historical Quinta Montes Molina, and an excursion to the archeological site of Dzibilchaltún including a swim at the famous cenote. PASCOS 2012 was possible thanks to the generous support of the following sponsors: CONACyT (Consejo Nacional de Ciencia y Tecnología), UNAM (Universidad Nacional Autónoma de México: Consejo Técnico de la Investigación Científica, Instituto de Ciencias Nucleares, Instituto de Física), Cinvestav, (Centro de Estudios Avanzados del IPN: U.

  12. Atmospheric Science and the CFC Industry

    2012-12-01

    Industry involvement with developing atmospheric science and subsequent regulations to protect ozone was unusual. Chlorofluorocarbon manufacturers were research-based businesses accustomed to understanding the science behind product-related issues. When Lovelock's measurements in 1971 implied most of the cumulative production of CFCs remained in the atmosphere, global CFC producers funded academic research to identify natural sinks for the materials. The Fluorocarbon Program Panel (FPP) began in 1972, but changed focus to atmospheric photochemistry following Rowland and Molina's work in 1974. Despite early vociferous opposition, especially by the CFC-using aerosol industry, to any regulations, leaders among the producers worked to build their scientific understanding, expanding FPP funding and launching internal work in modeling and ozone trend analysis. The key first question for industry was not how much depletion might occur, but whether it would occur at all. If so, regardless of the amount, regulations and a major transition would be required in CFC-using industries, and the response would need to be global and prompt. So long as that basic question was in doubt, some businesses and countries would resist the economic cost of action. In the meantime, the producing industry worked to identify potential alternatives and to communicate atmospheric science to the downstream industries. Although the industry science effort was often disparaged as an attack on "real" science, my only assignment when I joined DuPont's Central Research Department in 1979 was to understand and contribute to the science, keeping both the company and our customers informed. Our modeling results were published freely. FPP funding led to better knowledge of the ClO + O rate constant, significantly increasing depletion in model calculations; supported the development of the techniques used to measure in situ atmospheric ClO, so important in later strengthening the case for chlorine

    reflected in spectacular results. Much research for technology development has been done under co-ordinated research programmes from 1972 onwards and technology transfer is now undertaken through a number of technical assistance projects in countries such as Ghana, Panama, Zambia, Uganda, Thailand. During 1988 we may strengthen co-operative research on the use of in-vitro techniques in this field. While most emphasis in the Section's research programmes is technology advancement, more work is actually concerned with assisting plant breeders in developing countries through training, advice and other support. The Section services 40 country projects and 3 regional projects under the IAEA Programme of Technical Assistance and Co-operation. During 1987, 33 fellowship holders completed their training abroad and two training courses were held, one at the IAEA Laboratory Seibersdorf, the other one at the National Agricultural University La Molina in Peru. The success of mutation breeding all over the world can best be judged by the fact that the two issues of our Mutation Breeding Newsletter printed in 1987 listed 106 additional cultivars derived from mutation induction or the use of induced mutants in cross breeding. The Plant Breeding Unit of the IAEA Laboratory at Seibersdorf (Austria) continued to place much emphasis on technology development for mutation breeding (including in-vitro culture techniques) of banana, plantain and other vegetatively propagated crops. As a service for breeders of seed propagated crops, numerous seed samples have been given mutagenic treatments with gamma rays or fast neutrons and the laboratory will now also start to work on mutation breeding using haploids. Bob Conger from the University of Tennessee (Oak Ridge, USA), during a one year sabbatical, helped us to make advances in somatic embryogenesis from single cells, which is so important for improving the efficiency of mutation breeding using in-vitro cultures

    Full Text Available S’appuyant sur la relation éthico-politique entre la mémoire et la justice dans le sens proposé par Walter Benjamin et Jacques Derrida, cet article porte sur le rétablissement de la mémoire historique des victimes de la dictature de Francisco Franco (1939-1975. Pour ce faire, il oppose le roman Beltenebros (1989 d’Antonio Muñoz Molina et la récente loi espagnole « loi de la mémoire historique » (2007. En juxtaposant le roman et la loi, cet article vise à retracer dans chaque texte une série de pratiques récurrentes de représentations (mots, images, expressions qui cherchent à rendre justice aux victimes, avec un succès inégal. Les expressions récurrentes du roman (par exemple, les ombres, le refoulé, l’éternel retour, les fantômes et la cécité soulignent l’importance de surmonter les « fantômes du passé ». La loi, quant à elle, se concentre sur d’autres mots et images (par exemple, la fondation, la réconciliation, la concorde et la fermeture qui font allusion à l’idée du progrès historique sans une reconnaissance appropriée des injustices du passé. Ce faisant, la loi devient un lieu de commémoration pour la Transition espagnole, mais pas pour le rétablissement de la mémoire des victimes. La ré-appropriation de la loi de « l’esprit de la Transition » révèle la peur profonde de l’Espagne d’affronter les fantômes du passé, une peur qui peut être perçue encore aujourd’hui.Drawing on the ethico-political relationship between memory and justice in the sense proposed by Walter Benjamin and Jacques Derrida, this article addresses the recovery of the historical memory of the victims of Francisco Franco’s dictatorship (1939–1975.

    "Piedra Dorada" was used to construct some of the most important heritage buildings in the cities of Úbeda and Baeza, in Jaén (Spain). UNESCO declared these cities World Heritage Cities in 2003. Although there are some Iberian or Roman ruins in which is already possible to see the use of this stone, it is from the XVI century when "Piedra Dorada" is extensively used in the construction of the main historical buildings. Some of well-known monuments are Vázquez de Molina Palace or chain Palace (XVI), San Salvador Church (Sacred Chapel of El Salvador) (XVI) o the Royal Colegiata of Santa María la Mayor de los Reales Alcázares (XVI) in Úbeda or the Justice House-The House of the Corregidor (XVI), the Saint Cathedral of the Natividad de Nuestra Señora (XVI) or Jabalquinto Palace (XV), in Baeza, among many others. "Piedra Dorada" includes several varieties with similar mineralogical and chemical characteristics, called "Piedra Viva" or "Jabaluna", more cemented and used mainly with structural purposes (ashlars, columns, etc) and "Piedra Franca", less cemented and used mainly with decorative purposes (façades, statues, etc). From a geological point of view, "Piedra Dorada" is a medium to fine grain size bioclastic calcarenite, part of the upper Miocene-Pliocene deposits of the Guadalquivir Basin (Post Orogenic Neogene Basins of the Betic Chains). It is made up of quartz (8% to 29%), calcite and/or dolomite (34% to 80%), and some feldspar. The intergranular calcite cement proportion varies between 7% and 33%. Physical and mechanical properties are highly variable depending on the variety. "Piedra Viva" has an open porosity of 5,2%, bulk density of 2,63 g/cm3, water absorption at atmospheric pressure between 1,5-2,7 %, compressive strength (dry) between 20,1-18,0 MPa, flexural resistance (dry) between 87,3-77,0 MPa and salt crystallization loss of mass of 2,5%. "Piedra Franca" has an open porosity of 24,3%, bulk density of 2,00 g/cm3, water absorption at atmospheric

    Full Text Available The red sea urchin Loxechinus albus, an economically important species oceurring along the Chilean littoral benthic systems, has been heavily exploited by artisanal fisheries in recent decades. However, basic knowledge of its trophic biology is still scarce. Studies of this kind are critical to the successful development of farming techniques as an alternative to the harvest of natural populations. The aims of this study were to quantify the composition of L. albus' natural diet, to determine the assimilation efficieney of the most important dietary components, and to experimentally examine the species' trophic selectivity. Adult and juvenile specimens were sampled in spring 1993 and summer, fall and winter 1994 from the shallow subtidal zone of Iquique, northern Chile. Neither juveniles ñor adults showed significant seasonal differences in dietary composition. The main Ítems in the diet were the green alga Ulva sp. for juveniles and the kelp Lessonia sp. for adults. In adults, assimilation efficieney (as percentage of the total organic matter ingested was not significantly different among individuals that consumed Lessonia sp. (48.7 %, Ulva sp. (44.6 % and Macrocystis (38.1 %, whereas in juveniles assimilation efficieney was significantly higher for individuals fed on the chlorophyte Ulva sp. (55.4 %, followed by Lessonia sp. (35.0 % and Macrocystis (25.5 %. These results suggest that L. albus undergoes an ontogenetic shift in the diet, consisting of a differential foraging strategy between juveniles and adults.El erizo Loxechinus albus (Molina, 1782 es un recurso de gran importancia económica en los sistemas bentónicos costeros, y que se encuentra bajo una fuerte presión de explotación. Sin embargo, los antecedentes sobre diversos aspectos básicos de su biología trófica son aún escasos. Estudios de esta naturaleza son importantes en razón a que constituyen la base para el desarrollo de técnicas de cultivo exitosas, alternativa a la

    all scenario slips for central Andes, and for an average soil condition, exhibit similar amplitudes and attenuation characteristics with distance as the PGA and PGV values observed during the 2010 Maule (Mw 8.8), and 2011 Tohoku-oki (Mw 9.0) earthquakes. Our results clearly indicate that the simulated ground motions for scenarios with deep rupture nucleations (~40 km) are consistently smaller than the ground motions obtained for shallower rupture nucleations. We also performed strong ground motion simulations in metropolitan Lima by using the aforementioned slip scenarios, and incorporating site amplifications obtained from several microtremors array surveys conducted at representative geotechnical zones in this city. Our simulated PGA and PGV in Lima reach values of 1000 cm/s^2 and 80 cm/s. Our results show that the largest values of PGA (at Puente Piedra district, Northern Lima) are related with short period site effects, whereas the largest values of PGV are related with large site amplifications for periods from 1s to 1.5s (at Callao, Villa el Salvador and La Molina districts). Our results also indicate that the simulated PGA and PGV in central Lima (Parque de la Reserva) are in average 2~3 times larger than the values recorded by a strong motion instrument installed at this location, during the 1974 (Mw8.0) and 1966 (Mw8.0) earthquakes off-shore Lima.

  7. Aqueous aerosol may build up large upper tropospheric ice supersaturation

    Keywords: ice supersaturation, upper tropospheric cirrus clouds, freezing of aqueous aerosol. Observations often reveal enhanced and persistent upper tropospheric (UT) ice supersaturation, Si up to 100%, independently of whether cirrus ice clouds are present or not (Krämer et al., 2009; Lawson et al., 2008). However, a water activity criterion (WAC) (Koop et al., 2000) does not allow the formation of Si > ~67% by the homogeneous freezing of aqueous droplets even at the lowest atmospheric temperature of ~185 K. For aqueous aerosol the WAC predicts the existence of a so called homogeneous ice nucleation threshold which, being expressed as Si, is between ~52 and 67% in the temperature range of ~220 - 185 K. The nature of the formation of large Si remains unclear. Since water vapor is the dominant greenhouse gas it is important to know the nature of the accumulation and persistence of water vapor in the UT. We studied the freezing behavior of micrometer-scaled 3-, 4-, and 5-component droplets, which contain different weight fractions of H2O, H2SO4, HNO3, (NH4)2SO4, (NH4)HSO4, NH4NO3, and (NH4)3H(SO4)2. The study was performed between 133 and 278 K at cooling rates of 3, 0.1, and 0.05 K/min using differential scanning calorimetry (DSC) (Bogdan and Molina, 2010). The cooling rates of 0.1 and 0.05 K/min (6 and 3 K/h) are similar to the smallest reported synoptic temperature change of ~2 K/h (Carslaw et al., 1998). Using the measured freezing temperature of ice, Ti, and the thermodynamic E-AIM model of the system of H+ - NH4+ - SO42-- NO3-- H2O (Clegg et al., 1998), we calculated the corresponding clear-sky Si which would be built up immediately prior to the formation of ice cirrus clouds by the homogeneous freezing of aqueous aerosol of similar composition. We found that our calculated values of Si are both larger and smaller than the homogeneous ice nucleation threshold. For example, for the droplets of compositions of 15/10 and 20/10 wt % (NH4)3H(SO4)2/H2SO4, which

    Halogens are very reactive chemicals that are known to play an important role in anthropogenic stratospheric ozone depletion chemistry, first recognized by Molina and Rowland (1974). However, they also affect the chemistry of the troposphere. They are of special interest because they are involved in many reaction cycles that can affect the oxidation power of the atmosphere indirectly by influencing the main oxidants O3 and its photolysis product OH and directly, e.g., by reactions of the Cl radical with hydrocarbons (e.g., CH4).Already by the middle of the nineteenth century, Marchand (1852) reported the presence of bromine and iodine in rain and other natural waters. He also mentions the benefits of iodine in drinking water through the prevention of goitres and cretinism. In a prophetic monograph "Air and Rain: The Beginnings of a Chemical Climatology," Smith (1872) describes measurements of chloride in rain water, which he states to originate partly from the oceans by a process that he compares with the bursting of "soap bubbles" which produces "small vehicles" that transfer small spray droplets of seawater to the air. From deviations of the sulfate-to-chloride ratio in coastal rain compared to seawater, Smith concluded that chemical processes occur once the particles are airborne.For almost a century thereafter, however, atmospheric halogens received little attention. One exception was the work by Cauer (1939), who reported that iodine pollution has been significant in Western and Central Europe due to the inefficient burning of seaweed, causing mean gas phase atmospheric concentrations as high as or greater than 0.5 μg m-3. In his classical textbook Air Chemistry and Radioactivity, Junge (1963) devoted less than three pages to halogen gas phase chemistry, discussing chlorine and iodine. As reviewed by Eriksson (1959a, b), the main atmospheric source of halogens is sea salt, derived from the bursting of bubbles of air which are produced by ocean waves and other

    This project was one of three collaborating grants funded by DOE/ASP to characterize the fine particulate matter (PM) and secondary PM precursors in the Mexico City Metropolitan Area (MCMA) during the MILAGRO Campaign. The overall effort of MCMA-2006, one of the four components, focused on i) examination of the primary emissions of fine particles and precursor gases leading to photochemical production of atmospheric oxidants and secondary aerosol particles; ii) measurement and analysis of secondary oxidants and secondary fine PM production, with particular emphasis on secondary organic aerosol (SOA), and iii) evaluation of the photochemical and meteorological processes characteristic of the Mexico City Basin. The collaborative teams pursued the goals through three main tasks: i) analyses of fine PM and secondary PM precursor gaseous species data taken during the MCMA-2002/2003 campaigns and preparation of publications; ii) planning of the MILAGRO Campaign and deployment of the instrument around the MCMA; and iii) analysis of MCMA-2006 data and publication preparation. The measurement phase of the MILAGRO Campaign was successfully completed in March 2006 with excellent participation from the international scientific community and outstanding cooperation from the Mexican government agencies and institutions. The project reported here was led by the Massachusetts Institute of Technology/Molina Center for Energy and the Environment (MIT/MCE2) team and coordinated with DOE/ASP-funded collaborators at Aerodyne Research Inc., University of Colorado at Boulder and Montana State University. Currently 24 papers documenting the findings from this project have been published. The results from the project have improved significantly our understanding of the meteorological and photochemical processes contributing to the formation of ozone, secondary aerosols and other pollutants. Key findings from the MCMA-2003 include a vastly improved speciated emissions inventory from on

    has participated. His translations encompass lyrical works as well as fiction and plays. Talvet has translated classical European poetry, such as the sonnets of Petrarch and Quevedo and Provençal poems, as well as the rhymed poems of American poets into Estonian with complete metrical correspondence and full rhymes. However, in the latest decades Talvet has expressed scepticism in the sense and feasibility of attempting to convey the rhyming complexities of the major European literatures into Estonian, a language with a considerably smaller potential for finding full rhymes. Accordingly, his three translations of Spanish Baroque drama (by Calderón and Tirso de Molina employ a liberal method of versification. In all his versatile activities as a poet, a translator, and a theorist of poetry, Professor Talvet has shown great devotion to developing and cultivating aesthetic values. A lot of his colleagues and students have benefited from his friendly advice. Thinking of his contributions to Estonia’s literary tradition, one may repeat and paraphrase the sentence that he used for the conclusion of his essay on the Catalan poet Salvador Espriu in 1977: “to write (and to translate poetry is to work for the benefit of the people.”

  20. The Global Approach to Quantum Field Theory

    Parts I and II develop the basic classical and quantum kinematics of fields and other dynamical systems. The presentation is conducted in the utmost generality, allowing for dynamical quantities that may be anticommuting (supernumbers) and theories subject to the most general possible gauge symmetry. The basic ingredients are action functionals and the Peierls bracket, a manifestly covariant replacement for the Poisson bracket and equal-time commutation relations. For DeWitt the logical progression is Peierls bracket {yields} Schwinger action principle {yields} Feynman functional integral although he points out that the historical development was in the opposite order. It must be pointed out that the Peierls-Schwinger-DeWitt approach, despite some advantages over initial-value formulations, has some troubles of its own. In particular, it has never completely escaped from the arena of scattering theory, the paradigm of conventional particle physics. One is naturally led to study matrix elements between an 'in-vacuum' and an 'out-vacuum' though such concepts are murky in situations, such as big bangs and black holes, where the ambient geometry is not asymptotically static in the far past and future. The newest material in the treatise appears in two chapters in part II devoted to the interpretation of quantum theory, incorporating some unpublished work of David Deutsch on the meaning of probability in physics. Parts III through V apply the formalism in depth to successively more difficult classes of systems: quantum mechanics, linear (free) fields, and interacting fields. DeWitt's characteristic tools of effective actions, heat kernels, and ghost fields are developed. Chapters 26 and 31 outline new approaches developed in collaboration with DeWitt's recent students C Molina-Paris and C Y Wang, respectively. The most of parts VI and VII consist of special topics, such as anomalies, particle creation by external fields, Unruh acceleration
