    2015-02-01

    Full Text Available Despite quite similar conditions (natural resources for electricity production from renewable energy sources (RES-E in three Baltic States (Estonia, Latvia and Lithuania, significant differences exist in these countries as to the RES-E production volume. In Latvia this volume is the highest, while in Estonia and Lithuania it is half as high. One of the factors that determine the RES-E production volumes is support policies, which in the Baltic States are different. The main objective of this work was to analyze and compare these support policies. The results have shown that for rapid RES-E development the most effective policy is to be market-oriented (as in Estonia, whereas for more stable development such policy should be producer-oriented (as in Lithuania.

    Human dura mater is the most external meningeal sheet surrounding the CNS. It provides an efficient protection to intracranial structures and represents the most important site for CSF turnover. Its intrinsic architecture is made up of fibrous tissue including collagenic and elastic fibers that guarantee the maintenance of its biophysical features. The recent technical advances in the repair of dural defects have allowed for the creation of many synthetic and biological grafts. However, no detailed studies on the 3D microscopic disposition of collagenic fibers in dura mater are available. The authors report on the collagenic 3D architecture of normal dura mater highlighting the orientation, disposition in 3 dimensions, and shape of the collagen fibers with respect to the observed layer. Thirty-two dura mater specimens were collected during cranial decompressive surgical procedures, fixed in 2.5% Karnovsky solution, and digested in 1 N NaOH solution. After a routine procedure, the specimens were observed using a scanning electron microscope. The authors distinguished the following 5 layers in the fibrous dura mater of varying thicknesses, orientation, and structures: bone surface, external median, vascular, internal median, and arachnoid layers. The description of the ultrastructural 3D organization of the different layers of dura mater will give us more information for the creation of synthetic grafts that are as similar as possible to normal dura mater. This description will be also related to the study of the neoplastic invasion.

    Full Text Available Este trabalho teve como objetivo avaliar a qualidade de chapas aglomeradas fabricadas com resíduos da madeira de Eucalyptus saligna, resultantes da picagem das toras para a confecção de cavacos utilizados na produção de celulose. As chapas foram produzidas com dois tipos de resíduos, palitos e serragem, sendo utilizados puros. O adesivo usado foi à base de uréia-formaldeído em proporções de 4; 8 e 12%, com base na massa seca das partículas, e as densidades nominais das chapas foram de 0,55; 0,65 e 0,75 g/cm3. Foram avaliadas propriedades de flexão estática, ligação interna, arrancamento de parafusos, absorção d'água e inchamento em espessura. Os valores obtidos das propriedades de flexão estática, ligação interna e arrancamento de parafusos aumentaram com a densidade da chapa, assim como com o teor de adesivo, independentemente do tipo de resíduo. No caso da absorção d'água, os valores aumentaram com a redução da densidade, tanto para chapas produzidas com partículas tipo palitos como para serragem. Para inchamento em espessura, os valores aumentaram com a diminuição do teor de adesivo, sem considerar o do tipo de resíduo utilizado. Os resultados permitem concluir que, usando-se tanto partículas tipo palitos quanto serragem com maiores percentagens de adesivo e maiores densidades, podem ser produzidas chapas com qualidade satisfatória.

  15. Potential role for MATER in cytoplasmic lattice formation in murine oocytes.

    Directory of Open Access Journals (Sweden)

    2010-09-01

    Full Text Available Mater and Padi6 are maternal effect genes that are first expressed during oocyte growth and are required for embryonic development beyond the two-cell stage in the mouse. We have recently found that PADI6 localizes to, and is required for the formation of, abundant fibrillar Triton X-100 (Triton insoluble structures termed the oocyte cytoplasmic lattices (CPLs. Given their similar expression profiles and mutant mouse phenotypes, we have been testing the hypothesis that MATER also plays a role in CPL formation and/or function.Herein, we show that PADI6 and MATER co-localize throughout the oocyte cytoplasm following Triton extraction, suggesting that MATER co-localizes with PADI6 at the CPLs. Additionally, the solubility of PADI6 was dramatically increased in Mater(tm/tm oocytes following Triton extraction, suggesting that MATER is involved in CPL nucleation. This prediction is supported by transmission electron microscopic analysis of Mater(+/+ and Mater(tm/tm germinal vesicle stage oocytes which illustrated that volume fraction of CPLs was reduced by 90% in Mater(tm/tm oocytes compared to Mater(+/+ oocytes.Taken together, these results suggest that, similar to PADI6, MATER is also required for CPL formation. Given that PADI6 and MATER are essential for female fertility, these results not only strengthen the hypothesis that the lattices play a critical role in mediating events during the oocyte-to-embryo transition but also increase our understanding of the molecular nature of the CPLs.

    Magnetic resonance imaging often demonstrates gadolinium (Gd) enhancement of the dura mater around meningiomas. The Gd-enhanced dura mater was histologically investigated to detect meningioma cells. Gd enhancement of the dura mater occurred in 11 (79%) of the 14 meningiomas studied, and extended as far as 35 mm from the tumor. Histological examination revealed generation of vascular-rich loose connective tissue at the surface of the dura in all five tumors examined. Some clusters of meningothelial cells were distributed in the loose connective tissue in three of the five specimens, and one cluster was obviously neoplastic. These observations suggest that clusters of meningioma cells occur in the Gd-enhanced dura mater around meningiomas. (author)

  3. A European Res publica

    Directory of Open Access Journals (Sweden)

    Ola Zetterquist

    2011-05-01

    Full Text Available The article analyses the fundamental constitutional enigma of the European Union (EU, namely whether the EU can be considered as a (from its Member States separate and independent constitutional legal order. The EU is often referred to as a legal order sui generis, i.e. of a unique character that defies traditional definitions. More specifically, the notion of an independent and separate EU is at odds with the idea of the sovereign state. The notion of the EU as a legal order sui generis is too much influenced by the models of the sovereign state and sovereignty (in the vein of Thomas Hobbes. The key component in the Hobbesian idea of sovereignty is freedom as non-interference. A sovereign state is consequently a state that is free from, i.e. not interfered with by, external actors like, for example, the EU. Put differently, either the EU is sovereign or the Member States are sovereign. By shifting the perspective to a neo-Roman republican understanding of freedom as non-domination the constitutional picture of the EU will become more nuanced. Res publica is best understood as what citizens hold in common and above their narrow self-interest. According to a republican notion of the constitution the purpose of the law is to eliminate the possibility of arbitrary domination. For that reason, not all interference is to be considered as a restriction of freedom but only those restrictions that cannot be justified according to the res publica. Viewed through the republican prism it can be argued that the EU represents an important advancement in securing freedom as non-domination without implying that the EU must become a state. The fundamental enigma can thus be rephrased as a clash between two diverging concepts of freedom. Whereas the EU will always be at odds with the idea of sovereignty (however framed it will be much easier to reconcile with the republican ideal.

    The effects of the addition of fibres of bacterial cellulose (FBC) to commercial starch of Mater-Bi(®) have been investigated. FBC produced by cultivating Acetobacter xylinum for 21 days in glucose-based medium were purified by sodium hydroxide 2.5 wt % and sodium hypochlorite 2.5 wt % overnight, consecutively. To obtain water-free BC nanofibres, the pellicles were freeze dried at a pressure of 130 mbar at a cooling rate of 10 °C min(-1). Both Mater-Bi and FBC were blended by using a mini twin-screw extruder at 160 °C for 10 min at a rotor speed of 50 rpm. Tensile tests were performed according to ASTM D638 to measure the Young's modulus, tensile strength and elongation at break. A field emission scanning electron microscope was used to observe the morphology at an accelerating voltage of 10 kV. The crystallinity (T c) and melting temperature (T m) were measured by DSC. Results showed a significant improvement in mechanical and thermal properties in accordance with the addition of FBC into Mater-Bi. FBC is easily incorporated in Mater-Bi matrix and produces homogeneous Mater-Bi/FBC composite. The crystallinity of the Mater-Bi/FBC composites decrease in relation to the increase in the volume fraction of FBC.

    NACHT leucine-rich-repeat protein 5 (NALP5)/maternal antigen that embryo requires (MATER) is an autoantigen in hypoparathyroidism associated with autoimmune polyendocrine syndrome type 1 (APS1) but is also expressed in the ovary. Mater is an autoantigen in experimental autoimmune oophoritis. The objectives of the study were to determine the frequency of NALP5/MATER autoantibodies (NALP5/MATER-Ab) in women with premature ovarian insufficiency (POI) and in patients with autoimmune Addison's disease (AAD) and to evaluate whether inhibin chains are a target for autoantibodies in POI. Autoantibodies against NALP5/MATER and inhibin chains-α and -βA were determined by radiobinding assays in 172 patients with AAD without clinical signs of gonadal insufficiency, 41 women with both AAD and autoimmune POI [steroidogenic cell autoimmune POI (SCA-POI)], 119 women with idiopathic POI, 19 patients with APS1, and 211 healthy control subjects. NALP5/MATER-Ab were detected in 11 of 19 (58%) sera from APS1 patients, 12 of 172 (7%) AAD sera, 5 of 41 (12%) SCA-POI sera, 0 of 119 idiopathic POI sera and 1 of 211 healthy control sera (P < .001). None of 160 POI sera, including 41 sera from women with SCA-POI and 119 women with idiopathic POI, and none of 211 healthy control sera were positive for inhibin chain-α/βA autoantibodies. NALP5/MATER-Ab are associated with hypoparathyroidism in APS1 but are present also in patients with AAD and in women with SCA-POI without hypoparathyroidism. Inhibin chains do not appear to be likely candidate targets of autoantibodies in human POI.

  8. Hypoglycemic depression of RES function.

    1976-07-01

    The intravascular removal rates of colloidal carbon and of biologically active endotoxin by the reticuloendothelial system (RES) were evaluated as a function of blood-glucose levels. There was a significant negative correlation of carbon clearance half time on blood glucose in both saline-treated and insulin-treated rats. Insulin hypoglycemia depressed RES carbon clearance with the maximal effect occurring at blood glucose values below 30 mg/dl. Insulin hypoglycemia also severely impaired the intravascular removal of endotoxin as evaluated by lethality bioassay in lead-sensitized rats. It is concluded that blood glucose may modulate RES phagocytic function and that the hypoglycemia of endotoxin shock may augment the shock state due to impairment of RES host defense clearance functions.

  17. RES: Regularized Stochastic BFGS Algorithm

    Science.gov (United States)

    Mokhtari, Aryan; Ribeiro, Alejandro

    2014-12-01

    RES, a regularized stochastic version of the Broyden-Fletcher-Goldfarb-Shanno (BFGS) quasi-Newton method is proposed to solve convex optimization problems with stochastic objectives. The use of stochastic gradient descent algorithms is widespread, but the number of iterations required to approximate optimal arguments can be prohibitive in high dimensional problems. Application of second order methods, on the other hand, is impracticable because computation of objective function Hessian inverses incurs excessive computational cost. BFGS modifies gradient descent by introducing a Hessian approximation matrix computed from finite gradient differences. RES utilizes stochastic gradients in lieu of deterministic gradients for both, the determination of descent directions and the approximation of the objective function's curvature. Since stochastic gradients can be computed at manageable computational cost RES is realizable and retains the convergence rate advantages of its deterministic counterparts. Convergence results show that lower and upper bounds on the Hessian egeinvalues of the sample functions are sufficient to guarantee convergence to optimal arguments. Numerical experiments showcase reductions in convergence time relative to stochastic gradient descent algorithms and non-regularized stochastic versions of BFGS. An application of RES to the implementation of support vector machines is developed.

    Full Text Available PURPOSE: The dura mater bioprosthesis was developed in the Department of Cardiopneumology of the Hospital das Clínicas of the University of São Paulo Medical School in 1971. Here, we present the clinical results of the dura mater bioprosthesis over 30 years of follow-up. METHODS: We studied 70 consecutive patients who underwent mitral or tricuspid valve replacement with a dura mater bioprosthesis between January 1971 and August 1972. RESULTS: The early mortality was 10% (7 patients. The follow-up was 87% complete (9 patients were lost to follow-up. Two patients were alive and asymptomatic 30 years after valve replacement; 33 patients underwent reoperations due to valve dysfunction, and 19 died during the follow-up period. At 30 years, the actuarial survival was 49.2 ± 8.6%; freedom from rupture, 27.0 ± 10.2%; freedom from calcification, 78.8 ± 8.6%; and freedom from reoperation, 18.8 ± 7.5%. CONCLUSIONS: The dura mater bioprosthesis played an important role in the treatment of patients with mitral and tricuspid valve disease. The low rate of thromboembolism and the long period of follow-up without evidence of valve dysfunction, which occurred for several of our patients, are important characteristics of these bioprosthesis.A bioprótese de dura-mater foi desenvolvida no Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo em 1971.

    Full Text Available Among the items of sculpture from the Capitoline collection now housed in the Museum of the Power Station Montemartini is a marble relief altar of the Claudian Period (E. Simon's dating dedicated to the mater deorum and the navis salvia and depicting the arrival of the goddess Cybele at Rome by ship. The dedicator is one Claudia Syntyche and the sculpture alludes to the legends attached to a much honored woman of the Claudian family whom Cicero, in his oration pro Caelio brought on stage in a cameo appearance to bolster his case against the controversial contemporary woman Clodia Metelli as one of the accusers of his client M. Caelius Rufus. This paper will consider questions raised by the iconography of the altar with reference to the development of Claudia's legend in Roman mythology and subsequently ask who was this Claudia the dedicator and why did she choose Magna Mater for her vow?

    1984-03-01

    We have examined the tensile viscoelastic properties of fresh and glycerol-preserved human dura mater, and correlated the results with structural information from the scanning electron microscope. The interwoven laminar structure of dura produces rather high flexural stiffness, while the crossed-fibrillar laminae produce planar mechanical isotropy. Glycerol storage shifts the stress-strain curve to lower strain, reduces stress relaxation and creep, and lowers the ultimate tensile strength and strain at fracture. These changes may be due to glyceraldehyde crosslinking, or to increased interfibrillar friction. The latter hypothesis suggests that glycerol storage may reduce the fatigue lifetime of the tissue.

    Immunoglobulin G4 (IgG4)-related disease is a well-known disorder characterized by an inflammatory reaction with an increase in the number of IgG4-positive plasma cells associated with sclerosis. IgG4-related disease often affects the dura mater with a pattern of diffuse thickening when the central nervous system is involved. However, some nodular dural thickening requires discrimination from tumors because of obviously different treatment options. We report of a case of IgG4-related disease with tumefactive dural involvement

    It is unclear whether fetal alcohol exposure contributes to alcohol use in adolescence. In this study, we examine the association between maternal alcohol use in pregnancy and adolescents' drinking patterns at age 14. The association of maternal alcohol exposure with early drinking was examined in 4363 adolescents taking part to the Mater University Study of Pregnancy (MUSP) and its outcomes, a population based birth cohort study commenced in Brisbane (Australia) in 1981. Mothers and children were followed up at birth, 5 and 14 years after the initial interview. Maternal alcohol use was assessed before and during pregnancy and at the 5 years follow-up. Adolescents' alcohol use was assessed at child age 14. In multivariable analysis those born of mothers who consumed 3+ glasses during pregnancy were at increased risk to report drinking 3+ glasses compared with those whose mothers reported no drinking or drinking up to 2 glasses. Comparisons controlling for drinking before pregnancy and at age 5 found the averaged odds ratio of maternal drinking in pregnancy on risk of reporting alcohol consumption of 3 and more glasses at age 14 was 2.74 (CI 1.70, 4.22). Our study suggests that they maybe a biological origin of early drinking. Further studies are needed to better disentangle the nature of the association and the role of other possible confounding factors.

    The sclera, the outermost sheath of the optic nerve and the dura mater have been investigated histologically and ultrastructurally. Although these tissues appear very similar under the light microscope, being dense connective tissues mainly composed of collagen bundles and a limited amount of cells and elastic fibres, they exhibit subtle differences on electron microscopy. In the dura and sclera collagen appears in the form of large, nonuniform fibrils, similar to those commonly found in tendons, while in the optic nerve sheath the fibrils appear smaller and uniform, similar to those commonly observed in reticular tissues, vessel walls and skin. Freeze-fracture also reveals these fibrils to have different subfibrillar architectures, straight or helical, which correspond to 2 distinct forms of collagen fibril previously described (Raspanti et al. 1989). The other extracellular matrix components also vary with the particular collagen fibril structure. Despite their common embryological derivation, the dura mater, optic nerve sheath and sclera exhibit diversification of their extracellular matrix consistent with the mechanical loads to which these tissues are subjected. Our observations indicate that the outermost sheath of the optic nerve resembles the epineurium of peripheral nerves rather than the dura to which it is commonly likened.

    The immunohistochemical profile of neurotrophins and their receptors in the human cranial dura mater was studied by examining certain dural zones in specimens harvested from different regions (frontal, temporal, parietal and occipital). Dural specimens were obtained during neurosurgical operations performed in ten patients for surgical treatment of intracranial lesions (meningiomas, traumas, gliomas, vascular malformations). The dural fragments were taken from the area of the craniotomy at least 8 cm from the lesion as well as from the area in which the meningioma had its dural attachment. Immunohistochemical characterization and distribution of neurotrophins, with their receptors, were analyzed. The concrete role played by these neurotrophic factors in general regulation, vascular permeability, algic responsivity and release of locally active substances in the human dura mater is still controversial. Our study revealed a general structural alteration of dural tissue due to the invasivity of meningiomatous lesions, together with an improved expression of brain derived neurotrophic factor (BDNF) in highly proliferating neoplastic cells and an evident production of nerve growth factor (NGF) in inflammatory cells, suggesting that BDNF has a role in supporting the proliferation rate of neoplastic cells, while NGF is involved in the activation of a chronic inflammatory response in neoplastic areas.

    Recent studies demonstrate that Earth and Marine Sciences are not properly treated in scholastic programs and in textbooks are included in a superficial way. These topics are interdisciplinary and experimental (biology, ecology, oceanography and geology) and the recent advance in these fields is strictly linked to technologic improvement. School cannot keep up with the huge advances of knowledge experimented in the last 20 years, also for the lack of didactic laboratories sufficiently updated to support experimental activities. In this context, in 2014-15 three Italian Research Institutes (INGV, ISMAR-CNR and ENEA-CRAM) have decided to support the Unified School District "ISA 10"of Lerici (Liguria, Italy) - comprehensive of kindergartner, primary and middle schools - to develop the project MATER - Pianeta Terra-Mare (Planet Earth and Sea). The acronym MATER (MARe and TERra) has also a gender value, as people involved in the projects were women, mostly researchers and teachers, which have worked side by side with other women belonging to environmental and cultural associations of the territory. This heterogeneous group has a common objective: to promote the diffusion of a scientific culture and to sensitize students from 3 to 14 years towards problems occurring in marine and terrestrial environments, fostering the settlement of a sustainable attitude to the exploitation of natural resources and consciousness to natural hazards, such as earthquakes and floods, quite common in the Ligurian region. MATER has been considered as one of the best projects funded by MIUR (Italian Ministry of Education, University and Research) inside the Dissemination of Scientific and Technological Culture call for the year 2014. Natural hazards (Planet Earth) and the chemical-physical aspects and resources of the marine environment (Planet Sea) were the two modules of the project. Planet Earth developed through Piovono Idee!

Su construcción, enmarcada dentro de un plan más amplio acometido por el Arzobispado de Milán, supuso un gran avance en varios campos relacionados, principalmente, con la modernidad de la arquitectura sacra, la construcción y las nuevas tecnologías. Incorpora el uso no solamente del hormigón, material poco utilizado hasta ese momento en construcciones sacras, sino que, además, introduce un sistema de prefabricación y postesado “In situ” para la ejecución de la estructura que muestra el interés de los técnicos de la época por hallar nuevos medios de sistematización de la construcción. El sistema constructivo de cerramiento utilizado permite delimitar el espacio litúrgico mediante una piel translúcida que rodea el espacio, permitiendo la entrada de luz natural durante el día y la iluminación del entorno durante la noche. La presente investigación trata sobre las diferentes soluciones que se han empleado en la resolución de las fachadas de cerramiento, haciendo especial hincapié en la solución utilizada en la última rehabilitación a la que ha sido sometida.

The results show that the (3DC) exhibits a higher compression strength (1.2kN cm -2 in deep frozen states. Rehydration of the freeze-dried bone chips after 15 min with normal saline solution restores the strength of materials by 30%. The tensile strengths of fascia lata and dura mater are also studied. A marked decrease of tensile strength is noted in the irradiated and freeze-dried samples, however, reconstitution with normal saline solution restores the tensile strength of the tissues to about 40-56%.

    Full Text Available In this essay I develop a blasphemy counter-discourse arguing that it was ecclesial and state authorities who committed blasphemies, which were condemned by Pussy Riot’s punk-prayer. Thus, the performance in this respect may be interpreted as an anti-blasphemy protest. The blasphemy list includes the collaboration of the church with the authoritarian state, known as heresy of Sergianism; Caesar and Temple idolatry, blasphemy against the Holy Spirit, Virgin Mary and Folly for Christ’s sake. The punk-prayer may be interpreted as a feminine version of the Lord’s Prayer – Mater Nostra. Several corporeal narratives in the background – women’s dress code and rape debates, Virgin Mary’s belt, and its alleged miraculous ability to help women to deliver a baby – may be seen as allegories of feminist vs. patriarchal opposition in Russian religious and political culture.

    Within the frame of the MTPII-MATER project (MAST), the distribution of 90 Sr and 137 Cs in the Mediterranean Sea was modelled, as these radionuclides are useful tracers of water circulation. The Mediterranean Sea was divided into 81 boxes, corresponding to 21 regions, taking into account water mass circulation, bathymetry and data availability. Transfer rates were obtained from the MOM model run under MEDMEX conditions. The model was run with realistic inputs, which included weapons global fallout, Chernobyl 137 Cs, nuclear industry and river runoff. It was observed that existing data are scarce, especially in the eastern Mediterranean. In general, model predictions agreed well with observations, showing maximum concentrations in surface waters and maxima due to global fallout ( 137 Cs and 90 Sr) and to the Chernobyl accident ( 137 Cs only).

    To evaluate effect of sellar reconstruction during pituitary adenoma resection surgery by the endoscopic endonasal transsphenoidal approach using artificial cerebral dura mater patch.This was a retrospective study of 1281 patients who underwent endoscopic transsphenoidal resection for the treatment of pituitary adenomas between December 2006 and May 2014 at the Neurosurgery Department of the People's Liberation Army General Hospital. The patients were classified into 4 grades according to intraoperative cerebrospinal fluid (CSF) leakage site. All patients were followed up for 3 months by telephone and outpatient visits.One thousand seventy three (83.7%) patients underwent sellar reconstruction using artificial dura matter patched outside the sellar region (method A), 106 (8.3%) using artificial dura matter patched inside the sellar region (method B), and 102 (8.0%) using artificial dura matter and a mucosal flap (method C). Method A was used for grade 0-1 leakage, method B for grade 1 to 2 leakage, and method C for grade 2 to 3 leakage. During the 3-month follow-up, postoperative CSF leakage was observed in 7 patients (0.6%): 2 among patients who underwent method B (1.9%) and 5 among those who underwent method C (4.9%). Meningitis was diagnosed in 13 patients (1.0%): 2 among patients who underwent method A (0.2%), 4 among those who underwent method B (3.8%), and 7 among those who underwent method C (6.7%).Compared with other reconstruction methods, sellar reconstruction surgery that only use artificial dura mater as repair material had a low rate of complications.

    Electrical stimulation of the trigeminal ganglion has been widely used as a model of nociception, characterizing migraine. This treatment is known to evoke release of neuropeptides and neurotransmitters from nerve fibers of the dura mater. On the basis of immunocytochemical investigations, we found that under normal conditions, surface membranes of Schwann cells surrounding nerve fibers in the supratentorial dura mater display kynurenine aminotransferase-immunoreaction (KAT-IR); also KAT-IR are the granules of mast cells and the cytoplasms of macrophages (histiocytes). In consequence of stimulation of the trigeminal ganglion, Schwann cells in the dura mater became conspicuously swollen while their KAT-IR decreased considerably; also KAT-IR of mast cells and macrophages decreased significantly. At the same time, nitric oxide synthase (NOS)-IR of nerve fibers in the dura mater increased, suggesting release of nitric oxide (NO), this is known to be involved in NMDA receptor activation leading to vasodilation followed by neurogenic inflammation. Because kynurenic acid (KYNA) is an antagonist of NMDA receptors, we hypothesize that KYNA and its synthesizing enzyme, KAT, may play a role in the prevention of migraine attacks.

    Some lectins were used to study the localization of sugar residues on the endothelial cell surface in the pia mater blood vessels of control (WKY) and hypertensive rats (SHR). The lectins tested recognized the following residues: beta-D-galactosyl (Ricinus communis agglutinin 120, RCA-1), alpha-L-fucosyl (Ulex europaeus agglutinin, UEA-1), N-acetylglucosaminyl and sialyl (Wheat germ agglutinin, WGA), N-glycolyl-neuraminic acid (Limax flavus agglutinin, LFA), and N-acetyl-D-galactosaminyl (Helix pomatia agglutinin, HPA). Several differences were revealed in the presence of sugar receptors on the surface of endothelial cells between the control and the hypertensive rats. Our studies showed also differences in the localization of the tested glycoconjugates between pial capillaries, small, medium-size and large pial arteries. The histochemical evaluation of alkaline phosphatase revealed an increased activity of the enzyme in the pial vessels of SHRs as compared with control rats with a similar localization of the enzyme activity. Some differences in the distribution of lectin binding sites and alkaline phosphatase activity could be associated with the different functions of particular segments of the pial vascular network.

    Creutzfeldt-Jakob disease (CJD) is a fatal neurodegenerative disorder that, according to the most well accepted hypothesis (1), is caused by replicating, transmissible, abnormal forms of a host-encoded prion protein (prions). Most CJD cases occur spontaneously (sporadic CJD) or are inherited (genetic CJD). Iatrogenic CJD can occur after exposure to prion-contaminated instruments or products in medical/surgical settings. Cadaveric dura mater graft-associated CJD (dCJD) accounts for a common form of iatrogenic CJD. This report summarizes the epidemiologic features of 154 cases of dCJD identified in Japan during 1975-2017; these cases account for >60% of dCJD cases reported worldwide (1,2). The unusually high prevalence of dCJD in Japan was first reported in 1997 (3). In 2008, a single brand of graft (Lyodura [B. Braun Melsungen AG, Melsungen, Germany]), frequently used as a patch in neurosurgical procedures, was identified as the probable vehicle of transmission (4). No international recall of the implicated Lyodura occurred, the product had a relatively long shelf life, and the grafts were used frequently in Japanese patients with non-life-threatening conditions (4,5). Since 2008, additional cases have been ascertained, reflecting the identification of previously missed cases and the occurrence of new cases with longer latency periods (interval from exposure to symptom onset) for dCJD (up to 30 years), underscoring the importance of maintaining surveillance for dCJD.

    masculinity and horsemanship conveys the impression that women had nothing to do with horses. This is true for many situations. The circus arena, however, seems to have been an exception as women could perform there. At the heart of the performances was not only equestrianism, but also the notion of gender......The purpose of this article is to analyse gender relations in equestrianism from the beginning of the 19th to the first decades of the 20th century. Focus will be on the female horse riding circus artists, the écuyères. The fact that women were circus riders at this time is interesting as in many....... It is even likely that ”doing gender” was an indispensable part of the show, as the allure of the écuyères depended on the embodiment and presentation of seemingly incompatible features: beauty, grace and femininity as well as mastery of an art that was a traditionally male domain....

  12. Laser bonding with ICG-infused chitosan patches: preliminary experiences in suine dura mater and vocal folds

    Laser bonding is a promising minimally invasive approach, emerging as a valid alternative to conventional suturing techniques. It shows widely demonstrated advantages in wound treatment: immediate closuring effect, minimal inflammatory response and scar formation, reduced healing time. This laser based technique can overcome the difficulties in working through narrow surgical corridors (e.g. the modern "key-hole" surgery as well as the endoscopy setting) or in thin tissues that are impossible to treat with staples and/or stitches. We recently proposed the use of chitosan matrices, stained with conventional chromophores, to be used in laser bonding of vascular tissue. In this work we propose the same procedure to perform laser bonding of vocal folds and dura mater repair. Laser bonding of vocal folds is proposed to avoid the development of adhesions (synechiae), after conventional or CO2 laser surgery. Laser bonding application in neurosurgery is proposed for the treatment of dural defects being the Cerebro Spinal Fluid leaks still a major issue. Vocal folds and dura mater were harvested from 9-months old porks and used in the experimental sessions within 4 hours after sacrifice. In vocal folds treatment, an IdocyanineGreen-infused chitosan patch was applied onto the anterior commissure, while the dura mater was previously incised and then bonded. A diode laser emitting at 810 nm, equipped with a 600 μm diameter optical fiber was used to weld the patch onto the tissue, by delivering single laser spots to induce local patch/tissue adhesion. The result is an immediate adhesion of the patch to the tissue. Standard histology was performed, in order to study the induced photothermal effect at the bonding sites. This preliminary experimental activity shows the advantages of the proposed technique in respect to standard surgery: simplification of the procedure; decreased foreign-body reaction; reduced inflammatory response; reduced operating times and better handling in

    To adapt and standardize neural tissue mobilization exercises, quantify nerve root movement, and assess the anatomic effects of lumbar spinal nerve and dural mobilization in dogs. 15 canine cadavers. 5 cadavers were used in the preliminary part of the study to adapt 3 neural tissue mobilization physical therapy exercises to canine anatomy. In the other 10 cadavers, the L4 to L7 nerve roots and the dura at the level of T13 and L1 were isolated and marked. Movements during the physical therapy exercises were standardized by means of goniometric control. Movement of the nerve roots in response to each exercise was digitally measured. The effects of body weight and crownrump length on the distance of nerve root movement achieved during each exercise were also assessed. Each exercise was divided into 4 steps, and the overall distance of neural movement achieved was compared with distances achieved between steps. Neural tissue mobilization exercises elicited visible and measurable movement of nerve roots L4 to L7 and of the dura at T13 and L1 in all cadavers. The physical therapy exercises evaluated had measurable effects on nerve roots L4 to L7 and the dura mater in the T13 and L1 segments. These exercises should be evaluated in clinical trials to validate their efficacy as primary treatments or ancillary postsurgical therapy in dogs with disorders of the thoracolumbar and lumbosacral segments of the vertebral column.

    Full Text Available Four chiral Schiff base binuclear 3d-4f complexes (NdNi, NdCu, GdNi, and GdCu have been prepared and characterized by means of electronic and CD spectra, IR spectra, magnetic measurements, and X-ray crystallography (NdNi. A so-called artifact peak of solid state CD spectra, which was characteristic of oriented molecules without free molecular rotation, appeared at about 470 nm. Magnetic data of the complexes in the solid state (powder and in PMMA cast films or solutions indicated that only GdCu preserved molecular structures in various matrixes of soft maters. For the first time, we have used the changes of intensity of artifact CD peaks to detect properties of environmental (media solid state (KBr pellets, PMMA cast films, concentration dependence of PMMA in acetone solutions, and pure acetone solution for chiral 3d-4f complexes (GdCu. Rigid matrix keeping anisotropic orientation exhibited a decrease in the intensity of the artifact CD peak toward negative values. The present results suggest that solid state artifact CD peaks can be affected by environmental viscosity of a soft mater matrix.

    In the recent study given by Insinga et al. [J. Magn. Magn. Mater. 407, 369–376 (2016)], two kind of magnetic hysteresis loops, magnetization versus magnetic field strength (M-H), and magnetic induction versus magnetic field strength (B-H) of the permanent magnetic material with finite coercivity are involved. However, M-H and B-H functions are sensitive to the shape of magnetic element, moreover, M and B are possibly the multivalue functions at H=H{sub c}, perhaps the third kind magnetic hysteresis loop of magnetization versus magnetic induction (M-B) is more appropriate for predicting the phenomena of demagnetization and reversal of original remanence in magnet array. - Highlights: • Demagnetization is analyzed by the magnetic induction dependent remanence function M(B). • Partial demagnetization and remanence reversal may be distinguished by M(B) function.

    The purpose of this study was to assess the diagnostic value of epidural fat interposition between the dura mater and spinous process of L5 as an indirect sign of spondylolysis on mid-sagittal MR imaging of the lumbar spine. Mid-sagittal T1-weighted MR images of the lumbar spine of 85 patients with spondylolysis and 93 patients without pars interarticularis fractures were randomized and evaluated by a masked reader. After a training sample of five cases, the reader was asked to note the presence or absence of epidural fat interposition between the dura mater and spinous process of L5 on the randomized images. The epidural fat interposition between the dura mater and spinous process of L5 was noted in 67 out of the 85 patients with spondylolysis (78.8%) and three of the patients without pars interarticularis fracture (3.2%). The difference was statistically significant (P<0.01). This sign has a specificity of 96.7%, sensitivity of 78.8%, positive predictive value of 95.7%, negative predictive value of 83.3% and accuracy of 88.2% for diagnosis of spondylolysis. Epidural fat interposition between the dura mater and spinous process may be a helpful sign for the diagnosis of spondylolysis on mid-sagittal MR imaging of the lumbar spine. (orig.)

    Full Text Available Este artículo presenta un tipo de violencia familiar protagonizado por madres e hijas navarras de los siglos XVI y XVII. Las acu-saciones por lenocinio o alcahuetería contra las madres que emplearon a sus propias hijas en sus tratos de mediadoras sirven para ilustrar una forma de violencia que supone, entre otras cosas, una ruptura del amor materno. La preca-ria situación de la madre y las dificultades tras el fallecimiento del esposo —la gran parte de los casos están protagonizados por madres viu-das— fue el contexto general en el que se desarrollaron los malos tratos. La historia de estas mujeres representa un mal ejercicio de la autoridad materna y una forma de violencia hacia las hijas; una violencia no siempre física, pero sí emocional y psicológica.

    The paper presents the design features, the energy modelling and optical performance details of two pilot Intelligent Energy Buildings, (IEB). Both are evolution of the Zero Energy Building (ZEB) concept. RES innovations backed up by signal processing, simulation models and ICT tools were embedded into the building structures in order to implement a new predictive energy management concept. In addition, nano-coatings, produced by TiO2 and ITO nano-particles, were deposited on the IEB structural elements and especially on the window panes and the PV glass covers. They exhibited promising SSP values which lowered the cooling loads and increased the PV modules yield. Both pilot IEB units were equipped with an on-line dynamic hourly solar radiation prediction model, implemented by sensors and the related software to manage effectively the energy source, the loads and the storage or the backup system. The IEB energy sources covered the thermal loads via a south façade embedded in the wall and a solar roof which consists of a specially designed solar collector type, while a PV generator is part of the solar roof, like a compact BIPV in hybrid configuration to a small wind turbine.

    To examine the association between intrauterine growth and intelligence. Population based birth cohort study of sibling pairs born within a maximum of three years of each other. Mater-University women and children's hospital, Brisbane, Australia. 235 (470 children) sibling pairs. Among one randomly selected sibling from each pair verbal comprehension at age 5, general intelligence at age 14, and reading ability at age 14 increased linearly with increasing gestational age and sex standardised birth weight z scores. With adjustment for maternal age, race, and smoking during pregnancy, birth order, family income, and parental education the associations with verbal comprehension at age 5 and general intelligence at age 14 remained, whereas the association with reading ability at age 14 was attenuated to the null. Within sibling pairs, differences in intrauterine growth were positively associated with differences in verbal comprehension at age 5 (test score difference per one unit difference in birth weight z score = 1.52 (0.11 to 3.26)) and general intelligence at age 14 (1.09 (0.01 to 2.18)), but not with reading ability at age 14. Socioeconomic position or other fixed maternal characteristics do not seem to explain the positive association between intrauterine growth and childhood intelligence.

    Gregório Lopes (c. 1490-1550) was one of the most prominent painters of the renaissance and Mannerism in Portugal. The painting "Mater Misericordiae" made for the Sesimbra Holy House of Mercy, circa 1535-1538, is one of the most significant works of the artist, and his only painting on this theme, being also one of the most significant Portuguese paintings of sixteenth century. The recent restoration provided the possibility to study materially the painting for the first time, with a multianalytical methodology incorporating portable energy-dispersive X-ray fluorescence spectroscopy, scanning electron microscopy-energy-dispersive spectroscopy, micro-X-ray diffraction, micro-Raman spectroscopy and high-performance liquid chromatography coupled to diode array and mass spectrometry detectors. The analytical study was complemented by infrared reflectography, allowing the study of the underdrawing technique and also by dendrochronology to confirm the date of the wooden panels (1535-1538). The results of this study were compared with previous ones on the painter's workshop, and significant differences and similitudes were found in the materials and techniques used.

    The trigeminovascular system within the cranial dura mater is a possible cause of headaches. The aim of this study is to investigate macroscopically dural innervation around the middle meningeal artery (MMA) in the middle cranial fossa. Forty-four sides of the cranial dura overlying the skull base obtained from 24 human cadavers were stained using Sihler's method. Overall, the nervus spinosus (NS) from either the maxillary or mandibular trigeminal divisions ran along the lateral wall of the middle meningeal vein rather than that of the MMA. Distinct bundles of the NS running along the course of the frontal branches of the MMA were present in 81.8% of cases ( N = 36). Others did not form dominant nerve bundles, instead giving off free nerve endings along the course of the MMA or dural connective tissue. The distribution of these nerve endings was similar to that of the course of the frontal, parietal and petrosal branches of the MMA (11.4%). The others were not restricted to a perivascular plexus, crossing the dural connective tissues far from the MMA (6.8%). These findings indicate that the NS generally travels alongside the course of the frontal branches of the MMA and terminates in the vicinity of the pterion.

  20. Pulsed estrogen therapy prevents post-OVX porcine dura mater microvascular network weakening via a PDGF-BB-dependent mechanism.

    Directory of Open Access Journals (Sweden)

    Olga V Glinskii

    Full Text Available In postmenopausal women, estrogen (E2 deficiencies are frequently associated with higher risk of intracranial hemorrhage, increased incidence of stroke, cerebral aneurysm, and decline in cognitive abilities. In younger postpartum women and those using oral contraceptives, perturbations in E2 are associated with higher risk of cerebral venous thrombosis. A number of serious intracranial pathologic conditions linked to E2 deficiencies, such as dural sinus thrombosis, dural fistulae, non-parenchymal intracranial hemorrhages, migraines, and spontaneous cerebrospinal fluid leaks, involve the vessels not of the brain itself, but of the outer fibrous membrane of the brain, the dura mater (DM. The pathogenesis of these disorders remains mysterious and how estrogen regulates structural and functional integrity of DM vasculature is largely unknown. Here, we demonstrate that post ovariectomy (OVX DM vascular remodeling is manifested by microvessel destabilization, capillary rarefaction, increased vascular permeability, and aberrant angio-architecture, and is the result of disrupted E2-regulated PDGF-BB signaling within dura microvasculature. These changes, associated with the reduction in systemic PDGF-BB levels, are not corrected by a flat-dose E2 hormone replacement therapy (HRT, but are largely prevented using HRT schedules mimicking physiological E2 fluctuations. We demonstrate that 1 E2 regulates PDGF-BB production by endothelial cells in a dose-dependent manner and 2 optimization of PDGF-BB levels and induction of robust PDGF-mediated endothelial cell-vascular pericyte interactions require high (estrous E2 concentrations. We conclude that high (estrous levels of E2 are important in controlling PDGF-mediated crosstalk between endothelial cells and pericytes, a fundamental mechanism governing microvessel stability and essential for preserving intracranial homeostasis.

    This study aimed to evaluate extensive cranioplasty involving the frontal, parietal, occipital, and temporal bones without removing the floating bone flaps in the treatment of sagittal synostosis. Sixty-three children with sagittal synostosis, aged 5 months to 3 years, were included in the study. The frontal bone flap was removed using an air drill. The occipital and bilateral temporal bone flaps were cut open but not detached from the dura mater or fixed to produce floating bone flaps. The skull bone was cut into palisade-like structures. Brain compression from both sides and the base of the skull was released and the brain expanded bilaterally through the enlarged space. Only a long strip-shaped bone bridge remained in the central parietal bone. Subsequently, the frontal bone flaps and occipital bone flap were pushed towards the midline and fixed with the parietal bone bridge to shorten the anteroposterior diameter of the cranial cavity and allow the brain to expand bilaterally to correct scaphocephaly. Patients were followed up 1-5 years. Skull growth was excellent in all patients, the anteroposterior diameter was shortened, the transverse diameter was increased, the prominent forehead was corrected, and scaphocephaly improved significantly. There were no complications such as death and skull necrosis. Surgery without removing bone flaps is less traumatic and results in no massive bleeding. It can effectively relieve brain compression and promotes transversal expansion of the brain during surgery and subsequent normal brain development. The skull of young children is relatively thin and early surgery can easily achieve satisfactory bone reshaping. Our surgical technique is not only safe and effective but also can avoid subsequent psychological disorders caused by skull deformity.

  2. The "RESEAU MATER": An efficient infection control for endometritis, but not for urinary tract infection after vaginal delivery.

    "RESEAU MATER" is useful to monitor nosocomial infections in maternity and contributes to the decreasing trend of it, since its implementation. Specifically, this network demonstrates its efficiency in the control of endometritis following vaginal deliveries, but not in the control of urinary tract infections. The aim of this study is to determine whether the difference between the control of endometritis and of urinary tract infection could be explained by an unsuitable regression model or by an unsuitable care policy concerning urinary cares. This study includes (1) the analysis of historic data of the network and (2) the description of French guidelines for maternity cares and available evaluations, concerning endometritis and urinary tract infection prevention. Univariate and multivariate odds ratios (ORs) were calculated for the total study period of 1999-2013, for these infections and their risk factors. The endometritis frequency is decreasing, in association with no significant evolution of associated risk factors, but urinary tract infection frequency is constant, in association with a increasing trend of its risk factors such as intermittent catheterization and epidural analgesia. In French guidelines, all preventive measures against endometritis are clearly broadcasted by all field operators, and repeated audits have reinforced the control of their application. But preventive measures against urinary tract infection seem to be broadcasted exclusively in the circle of infection prevention agencies and not in the obstetrics societies or in the Health Ministry communication. Urinary tract infection prevention requires a clearer public and professional policy in favor of a more efficient urinary cares, with a specific target to maternity.

    This paper presents an extensive analysis of the Greek electricity market for the next 7-year period (2014–2020) based on an hour-by-hour simulation considering five different RES technologies, namely wind, PV, small hydro, biomass and CHP with emphasis on PV integration. The impact of RES penetration on the electricity market operation is evaluated under two different models regarding the organization of the Greek wholesale day-ahead electricity market: a mandatory power pool for year 2014 (current market design) and a power exchange for the period 2015–2020 (Target Model). An integrated software tool is used for the simulation of the current and the future day-ahead market clearing algorithm of the Greek wholesale electricity market. Simulation results indicate the impact of the anticipated large-scale RES integration, in conjunction with each market model, on specific indicators of the Greek electricity market in the long-term. - Highlights: • Analysis of the Greek electricity market for the next 7-year period (2014–2020) based on hour-by-hour simulation. • Five different RES technologies are considered with emphasis on PV integration. • A power pool (for 2014) and a power exchange (for 2015–2020) are considered. • Various market indicators are used for the analysis of the impact of the RES integration on the Greek electricity market. • Two alternative tariff schemes for the compensation of the new ground-mounted PV units from 2015 onwards are investigated

    Tissue-engineered cardiac patch aims at regenerating an infarcted heart by improving cardiac function and providing mechanical support to the diseased myocardium. In order to take advantages of electroactivity, a new synthetic method was developed for the introduction of an electroactive oligoaniline into the backbone of prepared patches. For this purpose, a series of electroactive polyurethane/siloxane films containing aniline tetramer (AT) was prepared through sol-gel reaction of trimethoxysilane functional intermediate polyurethane prepolymers made from castor oil and poly(ethylene glycol). Physicochemical, mechanical, and electrical conductivity of samples were evaluated and the recorded results were correlated to their structural characteristics. The optimized films were proved to be biodegradable and have tensile properties suitable for cardiac patch application. The embedded AT moieties in the backbone of the prepared samples preserved their electroactivity with the electrical conductivity in the range of 10 -4 S/cm. The prepared films were compatible with proliferation of C2C12 and had potential for enhancing myotube formation even without external electrical stimulation. © 2015 Wiley Periodicals, Inc.

    The Danish political energy and climate targets fixed in the RES (Renewable Energy Sources) directive require Denmark to reach a 30 % RES share of its total energy consumption in 2020. Besides, Danish national targets aim at wind power production to correspond to 50 % of domestic gross electricity consumption (status in 2015: 42 %). For 2050, the political target is to be free of fossil fuels in the whole energy sector - i.e. including transportation. The major part of variable RES in Denmark is wind energy, the remaining power consumption mainly based on biomass, gas and coal fired central power stations and local CHP plants. Some key figures: at the end of 2015, 5,076 MW wind power capacity and 783 MW of solar power capacity were installed in Denmark, with Danish peak load at ∼6.400 MW and the total electricity consumption at 33.6 TWh. Wind power is split into 3,805 MW onshore and 1.272 MW offshore installations. In 2015, wind power produced 14.1 TWh electricity (9.3 TWh onshore, 4.8 TWh offshore), which made a ∼42 % share of the Danish electricity consumption, while solar power produced 0.6 TWh. The high RES level is already today challenging the system e.g. concerning the need for flexibility on the one hand, or by pushing power plants delivering important system services out of the market on the other hand. To fulfill the political ambitions, new arrangements concerning the technical and market design incentivizing flexibility or ancillary services, such as frequency control and voltage control, are needed and currently under development. This article gives examples and illustrates the urgency by showing a real dispatch in a windy week. (authors)

    Knowledge of teachers in learning activities in the classroom has a close relationship with how well and how much students learn. Recently, a promising development in teacher education has appeared that centers on the academic construct of pedagogical content knowledge (PCK). This study was an exploratory study into a science teacher education program that seeks to build the foundations on which pre-service teachers can begin to build their pedagogical content knowledge (PCK). The program involved the use of Content Representations (CoRes), which was initially applied as component of a strategy for exploring and gaining insights into the PCK of in-service science teachers. This study involved the researcher and 20 students (third year) in a pre-service teacher education course (School Science I) in science education when the students worked to make content analysis on the digestive system topic. During the course, the students make their own CoRes through a workshop for digestive system topic individually, in pairs and whole class discussion. Data were recorded from students' CoRes, student reflective journals, interviews, and field notes recorded in the researcher's reflective journal. Pre-service teachers' comments from interviews and reflective journals were coded in relation to references about: (1) the effectiveness of variety strategies in building the knowledge bases required to design a CoRes and (2) their awareness and/or development of tentative components of future PCK for a digestive system topic as a result of CoRes construction. Observational data were examined for indications of increasing independence and competency on the part of student teachers when locating appropriate information for designing their CoRes. From this study, it is hoped that the pre-service science teachers are able to build knowledge and then transform it into a form of PCK for digestive system topic for their first classroom planning and teaching to teach digestive system

    The strong in-plane anisotropy of rhenium disulfide (ReS 2 ) offers an additional physical parameter that can be tuned for advanced applications such as logic circuits, thin-film polarizers, and polarization-sensitive photodetectors. ReS 2 also presents advantages for optoelectronics, as it is both a direct-gap semiconductor for few-layer thicknesses (unlike MoS 2 or WS 2 ) and stable in air (unlike black phosphorus). Raman spectroscopy is one of the most powerful characterization techniques to nondestructively and sensitively probe the fundamental photophysics of a 2D material. Here, we perform a thorough study of the resonant Raman response of the 18 first-order phonons in ReS 2 at various layer thicknesses and crystal orientations. Remarkably, we discover that, as opposed to a general increase in intensity of all of the Raman modes at excitonic transitions, each of the 18 modes behave differently relative to each other as a function of laser excitation, layer thickness, and orientation in a manner that highlights the importance of electron-phonon coupling in ReS 2 . In addition, we correct an unrecognized error in the calculation of the optical interference enhancement of the Raman signal of transition metal dichalcogenides on SiO 2 /Si substrates that has propagated through various reports. For ReS 2 , this correction is critical to properly assessing the resonant Raman behavior. We also implemented a perturbation approach to calculate frequency-dependent Raman intensities based on first-principles and demonstrate that, despite the neglect of excitonic effects, useful trends in the Raman intensities of monolayer and bulk ReS 2 at different laser energies can be accurately captured. Finally, the phonon dispersion calculated from first-principles is used to address the possible origins of unexplained peaks observed in the Raman spectra, such as infrared-active modes, defects, and second-order processes.

Este estudo teve como objetivo caracterizar o processo de descarte de drogas e resíduos dos serviços de saúde humana e veterinária em uma cidade de médio porte da Região Serrana de Santa Catarina. Foram realizadas visitas às unidades participantes, selecionadas por critérios de conveniência, contemplando unidades de saúde municipais, pet shops , clínicas veterinárias, hospital de atendimento humano, hospital de atendimento veterinário e empresas coletoras, totalizando 15 unidades participantes. A coleta de dados ocorreu de março a maio de 2014, com aplicação de questionários e roteiro de observação de campo. Os resultados evidenciaram deficiências no gerenciamento dos resíduos de medicamentos, assim como dos demais resíduos, nas etapas de segregação e armazenamento em instituições de atendimento humano e veterinário, com poucas exceções. As maiores dificuldades foram observadas nos estabelecimentos de atendimento veterinário, especialmente quanto à segregação e ao armazenamento dos resíduos contaminados, à falta de cuidado com material perfurocortante e às normas de biossegurança. A inexistência do Plano de Gerenciamento de Resíduos de Serviços de Saúde nas unidades de saúde e no hospital veterinário, assim como a falta de capacitações aos profissionais, a dissimilaridade no descarte de medicamentos entre os estabelecimentos e a falta de fiscalização por parte dos órgãos competentes foram os principais responsáveis pelo atual cenário de descarte inadequado dos resíduos na região.

    BonaRes is short for "soil as a sustainable resource for the bioeconomy". It is funded by the German Federal Ministry of Education and Research (BMBF) under the umbrella of the National Research Strategy BioEconomy 2030. BonaRes consists of ten interdisciplinary research project consortia and the 'BonaRes - Centre for Soil Research' (see also Wollschläger et al 2016). It is one task of the BonaRes Data Centre as part of the 'BonaRes - Centre for Soil Research', to collect data and meta-data of agricultural long-term field experiments (LTFE) in Germany. The definition of LTFE in the context of BonaRes is a minimum duration of twenty years and a static design. LTFE are essential research infrastructures for agricultural sciences and soil sciences amongst other disciplines. Some LTFE run since a very long time; the start of the oldest one in Germany was 1878. Therefore, in many cases valuable time series exist. Data sets of LTFE shall be compiled and made publicly available by the BonaRes Data Centre. The public availability together with an easy access will lead to an enhanced usability of the data. This probably makes the LTFE itself more valuable through an improved visibility and may also help to maintain the LTFE. Beyond the data compilation there is the possibility for every data owner to make a data publication, which offers an additional value for the data owner after his first right of use. A first step towards a joint database is a compilation of all existing LTFE in Germany with meta information to each trial. This information is shown in an interactive web map, what is completely new in that context. Besides the exact position of the LTFE the following metadata are shown: name of the LTFE, website (if available), institution, land use category, participation in existing networks, research theme, start (and maybe end) of the trial, and research parameters. Details on the meta information will be presented in the speech. Literature Wollschläger, U; Helming

    Full Text Available BACKGROUND AND OBJECTIVES: This study aimed to evaluate the transverse and longitudinal distensibility of the posterior human lumbar dura mater. Results are compared with previous literature on biomechanical property studies. Possible clinical implications were also examined. METHODS:Samples of human dural sac were obtained from autopsy studies in three adult male cadavers. Dural sac samples were sectioned longitudinally to measure transverse and longitudinal distensibility, thickness and circumference. RESULTS:It was recorded that the posterior lumbar dura mater was easily distensible only in the transverse direction. The longitudinal force required to distend and rupture the posterior lumbar dura mater samples is 3.5 to 6.7 times greater than the force to produce a transversal rupture. CONCLUSION: Depending on the local cerebrospinal fluid pressure, the documented easier transverse distensibility of the posterior lumbar dura mater may allow greater contact of the lumbar dural sac with the wall of the lumbar verterbral canal. This fact may affect the diffusion of solutions introduced into epidural space.Este estudo procura avaliar as distensibilidades transversal e longitudinal da dura máter lombar na sua porção posterior.

    Scintigraphy of the reticuloendothelial system (RES) was performed in 19 patients with polycythemia vera (PCV) and in 18 with secondary or relative polycythemia (PS). Bone marrow extension was found in all patients with PCV and in 11 of 18 patients with PS. The patients with PCV had a higher degree of extension than those with PS. Increased pelvic bone marrow activity was found in 16 of 19 PCV patients, but in none with PS. Splenomegaly was found in 9 patients with PCV, and in none with PS. It is concluded that RES scintigraphy in the majority of patients may differentiate between PCV and PS using the parameters pelvic bone marrow activity, bone marrow extension and splenic size.

    This study aims to meet the need for scientifically robust information on the gross effects (direct and indirect) as well as on the net effects (including both conventional replacement and budget effects) of renewable energy policies in Europe. Furthermore, the future development of RES in Europe will take place against the background of a global market for RES technology. This global market and the potential share of European industries in it will play a critical role in the potentials for growth and employment. This study aims to provide a sound scientific analysis of these issues. This report is divided into four main parts, A, B, C and D. While the first three covers the introduction, the theoretical approach, the modelling steps and structure of the report, the fourth part, part D, discusses in detail the models and results of the projects. It begins with chapter D 1 which describes past RES deployment and its costs. Then follows the past macroeconomic impacts presented by gross effects on employment and value added (D 2). Thereafter, the future potential (D 3) and future deployment (D 4) of renewable energy sources (RES) are discussed. Before the presentation of the future gross and net effects, the five scenarios used in the macro-economic models (D 5) are explained in detail. Finally we depict the future gross and net impacts on employment and GDP in D 6 and D 7, respectively. The comparison between the results of the two models and our conclusion for the study follows in chapter D 8 and 9

    Full Text Available Tem sido cada vez maior a preocupação das empresas do setor florestal em adotar práticas pautadas na conservação do solo e da água. Nesse sentido, este trabalho teve por objetivo avaliar o impacto do manejo dos resíduos da colheita, do preparo do solo e do uso de resíduos industriais, na fertilidade do solo e produtividade de eucalipto. O experimento foi iniciado após o corte raso de um plantio comercial de EUCALYPTUS GRANDIS, onde os resíduos da colheita foram manejados (retirada de todo o resíduo; remoção da casca e dos galhos com diâmetro superior a 3,0 cm; e manutenção de todos os resíduos na superfície do solo. Em seguida, realizaram-se o preparo do solo (com subsolador de uma e três hastes, a aplicação dos resíduos industriais (resíduo de celulose e cinzas na superfície do solo e o plantio de mudas de EUCALYPTUS GRANDIS X E. UROPHYLLA Foi utilizado o delineamento em blocos ao acaso, contendo oito tratamentos e quatro repetições. Os tratamentos consistiram da combinação dos diferentes tipos de manejo dos resíduos da colheita, preparo do solo e aplicação dos resíduos industriais. Cada parcela experimental foi composta por cinco linhas com 19 plantas cada. Aos 83 meses após o plantio, foram medidos o DAP (diâmetro à altura do peito e a altura das árvores, para cálculo do volume de madeira. A fertilização e a manutenção dos resíduos da colheita florestal elevaram os teores de Ca2+ e Mg2+ trocáveis no solo. A manutenção total dos resíduos vegetais na área após a colheita resultou em aumento de 71,7 m³ ha-1 de madeira, quando comparado à remoção de todos os resíduos. Não houve diferença entre os modos de preparo do solo com subsolador de uma e três hastes, quanto ao volume de madeira. Os maiores volumes de madeira foram obtidos dos tratamentos que receberam as maiores quantidades de resíduo de celulose e cinzas, ao mesmo tempo em que foi mantida parte do resíduo vegetal após a colheita

    This study aimed to evaluate the effort of applying frontal and occipital bones in extensive cranioplasty and preserving multiple cranial bone flaps adhered to the dura mater in the treatment of sagittal synostosis. From April 2008 to June 2013, sixty-three children with sagittal synostosis, aged 5 months to 3 years, were included in the study. The frontal bone flap was removed using an air drill. The occipital and bilateral temporal bone flaps were cut open but not detached from the dura mater or fixed to produce floating bone flaps. The skull bone was cut into palisade-like structures. Brain compression from both sides and the base of the skull was released and the brain expanded bilaterally through the enlarged space. Only a long strip-shaped bone bridge remained in the central parietal bone. Subsequently, the frontal bone flaps and occipital bone flap were pushed towards the midline and fixed with the parietal bone bridge to shorten the anteroposterior diameter of the cranial cavity and allow the brain to expand bilaterally to correct scaphocephaly. The CT images showed that both sides of the parietal bone of artificial sagittal groove gradually merged postoperative 1 year, and skull almost completely normal healing after operation 2 or 3 years, without deformity recurrence within 5 years. Among them all, 61 children's intelligence is normal and 2 children's lagged behind normal level, no further improvement. Patients were followed up 1 - 5 years (an average of 43 months). Skull growth was excellent in all patients, the anteroposterior diameter was shortened by 14.6 mm averagely, the transverse diameter was increased by 12.3 mm averagely, the prominent forehead was corrected, and scaphocephaly improved significantly. There were no complications such as death and skull necrosis. The application of frontal and occipital bones in extensive cranioplasty and preserving multiple cranial bone flaps adhered to the dura mater can be used in the treatment of sagittal

    The most recent EU member states seem to have important Renewable Energy Sources (RES) potential. However, they have serious structural difficulties in development and integration of RES policies. Indeed, the balanced development of RES between the member states is urgent today. The penetration of the RES in these member states is related to the existence of an appropriate environment (political, economical, social, and technological). The current paper is based on an analytical review and specific PEST analysis aiming to assess the current RES environment and the progress so far in each of these most recent EU members. (author)

    Experience with dissection of the cavernous sinus and the temporal bone is essential for training in skull base surgery, but the opportunities for cadaver dissection are very limited. A modification of a commercially available prototype three-dimensional (3D) skull base model, made by a selective laser sintering method and incorporating surface details and inner bony structures such as the inner ear structures and air cells, is proposed to include artificial dura mater, cranial nerves, venous sinuses, and the internal carotid artery for such surgical training. The transpetrosal approach and epidural cavernous sinus surgery (Dolenc's technique) were performed on this modified model using a high speed drill or ultrasonic bone curette under an operating microscope. The model could be dissected in almost the same way as a real cadaver. The modified 3D skull base model provides a good educational tool for training in skull base surgery.

    Full Text Available A demanda por produtos de origem animal vem aumentando gradativamente no mundo, e a expectativa é que haja um incremento nos próximos anos, juntamente com a produção. Em consequência disso, ocorre também acréscimo na geração de diferentes tipos de resíduos nas propriedades. Um dos resíduos que são gerados na produção animal são os resíduos de serviço de saúde animal (RSSA. Diante deste cenário, objetivou-se realizar uma revisão sobre o gerenciamento de RSSA. Os RSSA mesmo que produzidos em menor quantidade devem receber cuidado especial devido à capacidade de infectar e contaminar o meio ambiente e o ser humano. O gerenciamento de RSSA é importante para mitigar os impactos ambientais e sanitários. Nas propriedades rurais, é ainda pouco discutido e realizado. É importante buscar medidas para realizar a correta segregação e posterior reciclagem dos RSSA. A disposição final da maior parte destes resíduos é efetuada de forma inadequada. É de fundamental importância à implantação de um plano de gerenciamento de resíduos sólidos e que mais estudos sejam realizados na área.

    2013-06-01

    This report summarises the outcomes of a 30 months duration continuing education project entitled 'Urban Planners with Renewable Energy Skills' (UP-RES). The project was carried out by a multi-disciplinary international consortium with the aim of informing planners and related professionals about energy-efficient and CO{sub 2} reducing technologies, practices and systems that can be developed across urban areas to serve whole communities. This report provides an overview of the key issues: The overall project approach to devising a training program based on preceding training needs analysis The key tasks involved in creating the training materials The marketing of the training as well as evaluation results Best practise examples of RES in urban planning. The UP-RES project has focused on several major target groups. These include those groups directly involved in taking forward renewable energy projects for whom the UP-RES training was principally focused; those who wish to deliver such training programmes; and policy makers who are ultimately responsible for the decisions that govern how widely such technologies will be implemented. Each of these groups has its own perspective concerning renewable energy technologies so the report is structured accordingly: For professionals involved in implementation: Among those professions that are likely to become involved with renewable energy initiatives in urban areas are urban planners, architects, energy suppliers, developers, building owners, and consulting engineers. For these professionals chapters 3.2 (summary of training need analysis) and 4 (best practise examples) are most likely to appeal. For training experts and organisations: Training programmes that address the relevance of renewable energies in urban areas require a comprehensive set of materials. As an example of how to organise training courses and lessons learnt, chapter 3 might be interesting. For the generally interested: Renewable energies are

    In Part I, (J.A. Davidson and G. Schwartz, "Wear, creep, and frictional heating of femoral implant articulating surfaces and the effect on long-term performance--Part I, A review," J. Biomed. Mater. Res., 21, 000-000 (1987) it was shown that lubrication of the artificial hip joint was complex and that long-term performance is governed by the combined wear, creep, and to a lesser extent, oxidation degradation of the articulating materials. Importantly, it was shown that a tendency for heating exists during articulation in the hip joint and that elevated temperatures can increase the wear, creep, and oxidation degradation rate of UHMWPE. The present study was performed to examine closely the propensity to generate heat during articulation in a hip joint simulator. The systems investigated were polished Co-Cr-Mo alloy articulating against UHMWPE, polished alumina ceramic against UHMWPE, and polished alumina against itself. Frictional torque was also evaluated for each system at various levels of applied loads. A walking load history was used in both the frictional heating and torque tests. The majority of tests were performed with 5 mL of water lubricant. However, the effect of various concentrations of hyaluronic acid was also evaluated. Results showed frictional heating to occur in all three systems, reaching an equilibrium after roughly 30 min articulation time. Ceramic systems showed reduced levels of heating compared to the cobalt alloy-UHMWPE system. The level of frictional torque for each system ranked similar to their respective tendencies to generate heat. Hyaluronic acid had little effect, while dry conditions and the presence of small quantities of bone cement powder in water lubricant significantly increased frictional torque.

  14. Renewables portfolio, individual preferences and social values towards RES technologies

    The massive deployment of renewable energy sources represents a high priority for Greece in order to comply with the Directive 2009/28/EC on the promotion of the use of energy from renewable sources by 2020. In this perspective, Aegean islands especially Lesvos, are endowed with a considerable potential of a portfolio of renewables, a fact that the entrepreneurial interest has already been targeted. However, regulatory attempts for a massive penetration of renewables do not take seriously into account preferences and risk perceptions of local communities where the proposed projects are to be installed. The aim of this study is to investigate individual preferences and social values towards specific technologies of renewables in Lesvos island. We apply an open-ended contingent valuation survey in order to analyze factors shaping public attitudes towards a portfolio of renewable technologies and estimate the economic welfare (Willingness To Pay) of the preferred technologies. We argue that such information is relevant for energy policy design and the establishment of effective measures for the promotion of renewable energy sources. - Highlights: ► We investigate individual preferences and attitudes towards a portfolio of RES technologies. ► We elicit public acceptance for investing in specific RES technologies. ► We analyze factors shaping public preferences of the preferred technologies. ► We estimate the economic welfare of the preferred technologies

    On page 4090, B. Özyilmaz, C. H. Sow, and co-workers use a focused laser beam to modify the surface of a phosphorene device. With a simple focused laser beam, a part of the phosphorene can be scanned and converted into phosphorene-suboxide species, leaving behind a functional and active phosphorene-phosphorene suboxide junction in the device. Once the junction is formed, the photoresponsivity and photocurrent distribution of the device can be significantly altered with a qualitative difference in behavior. Photovoltaic-like behavior is observed, which is not found in the pristine sample. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    The stories in this issue of Narrative Inquiry in Bioethics demonstrate two important things. First these stories explore the space between bodily impairment and the social structures that both enable and constrain the flourishing of those who are differently embodied. The authors of these narratives resist the dominant biomedical interpretation of their impairments, but also demonstrate their dependency upon others--social, medical, or familial others. Second, in writing these narratives, the authors are also engaged in an act of identity formation, which sometimes challenge and sometimes embrace the label of disability. By telling their stories in the middle of the action of their lives--in media res, taking up or resisting the label of disability-they also demonstrate the way in which lives can be lived open to new possibilities and interpretations.

  20. The Nordic welfare model providing energy transition? A political geography approach to the EU RES directive

    2012-01-01

    The EU Renewable Energy Strategy (RES) Directive requires that each member state obtain 20% of its energy supply from renewable sources by 2020. If fully implemented, this implies major changes in institutions, infrastructure, land use, and natural resource flows. This study applies a political geography perspective to explore the transition to renewable energy use in the heating and cooling segment of the Swedish energy system, 1980–2010. The Nordic welfare model, which developed mainly after the Second World War, required relatively uniform, standardized local and regional authorities functioning as implementation agents for national politics. Since 1980, the welfare orientation has gradually been complemented by competition politics promoting technological change, innovation, and entrepreneurship. This combination of welfare state organization and competition politics provided the dynamics necessary for energy transition, which occurred in a semi-public sphere of actors at various geographical scales. However, our analysis, suggest that this was partly an unintended policy outcome, since it was based on a welfare model with no significant energy aims. Our case study suggests that state organization plays a significant role, and that the EU RES Directive implementation will be uneven across Europe, reflecting various welfare models with different institutional pre-requisites for energy transition. - Highlights: ► We explore the energy transition in the heating/cooling sector in Sweden 1980–2000. ► The role of the state is studied from a political geography perspective. ► The changing welfare model offered the necessary institutional framework. ► Institutional arrangements stand out as central to explain the relative success. ► The use of renewables in EU member states will continue to vary significantly.

    In its Directive 2009/28/EC the European Commission (EC) set an ambitious 20% target on the final consumption of energy from renewable sources (RES) in 2020 (European Commission, 2009). This EU-level target is divided into different domestic targets for each single Member State (MS). The MS-level targets do not always reflect the domestic RES potentials, creating a situation where certain MSs will have to deploy very expensive technologies in order to meet their target, while other countries are expected to reach their target at lower costs and even produce a RES surplus. In order to promote a more balanced distribution of costs, the Directive allows MSs to establish cooperation mechanisms. Three types of cooperation mechanisms are defined: a MS could buy the RES-credits associated with the surplus potential of other MSs via statistical transfers, could finance additional RES deployment in other MSs by engaging in joint projects, or could share (part of) its RES potential with other MSs by establishing joint support schemes.

    The introduction of a High-Resolution (Hi-Res) scan mode and another associated option that combines Hi-Res mode with the so-called High Definition (HD) reconstruction kernels (referred to as a Hi-Res/HD mode in this paper) in some multi-detector CT (MDCT) systems offers new opportunities to increase spatial resolution for some clinical applications that demand high spatial resolution. The purpose of this work was to quantify the in-plane spatial resolution along both the radial direction and tangential direction for the Hi-Res and Hi-Res/HD scan modes at different off-center positions. A technique was introduced and validated to address the signal saturation problem encountered in the attempt to quantify spatial resolution for the Hi-Res and Hi-Res/HD scan modes. Using the proposed method, the modulation transfer functions (MTFs) of a 64-slice MDCT system (Discovery CT750 HD, GE Healthcare) equipped with both Hi-Res and Hi-Res/HD modes were measured using a metal bead at nine different off-centered positions (0-16 cm with a step size of 2 cm); at each position, both conventional scans and Hi-Res scans were performed. For each type of scan and position, 80 repeated acquisitions were performed to reduce noise induced uncertainties in the MTF measurements. A total of 15 reconstruction kernels, including eight conventional kernels and seven HD kernels, were used to reconstruct CT images of the bead. An ex vivo animal study consisting of a bone fracture model was performed to corroborate the MTF results, as the detection of this high-contrast and high frequency task is predominantly determined by spatial resolution. Images of this animal model generated by different scan modes and reconstruction kernels were qualitatively compared with the MTF results. At the centered position, the use of Hi-Res mode resulted in a slight improvement in the MTF; each HD kernel generated higher spatial resolution than its counterpart conventional kernel. However, the MTF along the

    Drawing from relevant experiences in power systems around the world, this paper offers a review of existing policy support mechanisms for RES-E, with a detailed analysis of their regulatory implications. While recent studies provide an account of current RES-E support systems, in this paper we focus on some of the impacts these mechanisms have on the overall energy market structure and its performance. Given the rising importance of RES-E in systems everywhere, these impacts should no longer be overlooked. - Highlights: ► This paper offers a critical review of RES-E support mechanisms and their regulatory implications. ► The discussion focuses on how the different schemes impact the performance of the energy markets. ► We propose to redesign of current RES-E mechanisms to optimize incentives and market performance. ► Our recommendation is also to gradually move from price-based mechanisms to auctions.

    Operational research (OR) has become a hot topic at national meetings, international conferences and donor fora. The International Union Against Tuberculosis and Lung Disease (The Union) and Médecins Sans Frontières (MSF) Operational Centre Brussels strongly promote and implement OR with colleagues in low- and middle-income countries. Here we describe how the two organisations define OR, and explain the guiding principles and methodology that underpin the strategy for developing and expanding OR in those countries. We articulate The Union's and MSF's approach to supporting OR, highlighting the main synergies and differences. Then, using the Malawi National Tuberculosis Control Programme as an example, we show how OR can be embedded within tuberculosis control activities, leading to changes in policy and practice at the national level. We discuss the difficult, yet vitally important, issue of capacity building, and share our vision of a new paradigm of product-related training and performance-based OR fellowships as two ways of developing the necessary skills at country level to ensure research is actually performed. Finally, we highlight the need to consider and incorporate into practice the ethical components of OR. This is a key moment to be involved in OR. We are confident that in partnership with interested stakeholders, including the World Health Organization, we can stimulate the implementation of quality, relevant OR as an integral part of health service delivery that in turn will lead to better health for people, particularly for those living in the poorer parts of the world.

  15. RES hyperphagocytosis by rats with streptozotocin-induced diabetes mellitus.

    In contrast to previous studies of neutrophils from diabetic animals and humans in vitro and of macrophages from diabetic humans in vivo, which reported phagocytic depression, reticuloendothelial system (RES) hyperphagocytosis of colloidal carbon was observed in rats at 14 and 28 days after diabetes induction with streptozotocin (STZ). Carbon clearance half times were significantly enhanced to 6.3 +/- 0.79 and 8.1 +/- 1.04 min at 14 and 28 days post-STZ, respectively, compared with the nondiabetic value (12.7 +/- 0.98 min). The severity of uncontrolled STZ-induced diabetes in rats was confirmed by significant hypoinsulinemia, hyperglucagonemia, hyperglycemia, and hyperlipidemia. Although body weights of STZ-diabetic animals declined progressively, liver weights as a percent of body weight increased above the control value at 14 and 28 days post-STZ. In fact, expression of carbon phagocytosis as the corrected phagocytic index, which accounts for changes in liver and spleen weights relative to body weight, eliminated the significant difference between STZ-diabetic and nondiabetic animals. Antibiotic treatment of diabetic rats failed to alter the hyperphagocytosis, implying that a chronic bacterial infection was not the cause of phagocytic stimulation. Daily insulin replacements, but not a single large insulin dose to 14-day post-STZ rats, reversed the enhanced phagocytosis of colloidal carbon.

    Migraine is a debilitating neurological disorder where trigeminovascular activation plays a key role. We have previously reported that local application of Complete Freund's Adjuvant (CFA) onto the dura mater caused activation in rat trigeminal ganglion (TG) which was abolished by a systemic administration of kynurenic acid (KYNA) derivate (SZR72). Here, we hypothesize that this activation may extend to the trigeminal complex in the brainstem and is attenuated by treatment with SZR72. Activation in the trigeminal nucleus caudalis (TNC) and the trigeminal tract (Sp5) was achieved by application of CFA onto the dural parietal surface. SZR72 was given intraperitoneally (i.p.), one dose prior CFA deposition and repeatedly daily for 7 days. Immunohistochemical studies were performed for mapping glutamate, c-fos, PACAP, substance P, IL-6, IL-1β and TNFα in the TNC/Sp5 and other regions of the brainstem and at the C 1 -C 2 regions of the spinal cord. We found that CFA increased c-fos and glutamate immunoreactivity in TNC and C 1 -C 2 neurons. This effect was mitigated by SZR72. PACAP positive fibers were detected in the fasciculus cuneatus and gracilis. Substance P, TNFα, IL-6 and IL-1β immunopositivity were detected in fibers of Sp5 and neither of these molecules showed any change in immunoreactivity following CFA administration. This is the first study demonstrating that dural application of CFA increases the expression of c-fos and glutamate in TNC neurons. Treatment with the KYNA analogue prevented this expression.

    Small heat shock protein (sHSP)-B7 (HSPB7) is a muscle-specific member of the non-ATP-dependent sHSPs. The precise role of HSPB7 is enigmatic. Here, we disclose that zebrafish Hspb7 is a kinetically privileged sensor that is able to react rapidly with native reactive electrophilic species (RES), when only substoichiometric amounts of RES are available in proximity to Hspb7 expressed in living cells. Among the two Hspb7-cysteines, this RES sensing is fulfilled by a single cysteine (C117). Purification and characterizations in vitro reveal that the rate for RES adduction is among the most efficient reported for protein-cysteines with native carbonyl-based RES. Covalent-ligand binding is accompanied by structural changes (increase in β-sheet-content), based on circular dichroism analysis. Among the two cysteines, only C117 is conserved across vertebrates; we show that the human ortholog is also capable of RES sensing in cells. Furthermore, a cancer-relevant missense mutation reduces this RES-sensing property. This evolutionarily conserved cysteine-biosensor may play a redox-regulatory role in cardioprotection.

    By performing density functional theory-based calculations, we investigate how structural, electronic and mechanical properties of single layer ReS2 can be tuned upon hydrogenation of its surfaces. It is found that a stable, fully hydrogenated structure can be obtained by formation of strong S-H bonds. The optimized atomic structure of ReS2H2 is considerably different than that of the monolayer ReS2 which has a distorted-1T phase. By performing phonon dispersion calculations, we also predict that the Re2-dimerized 1T structure (called 1T {{}\\text{R{{\\text{e}}2}}} ) of the ReS2H2 is dynamically stable. Unlike the bare ReS2 the 1T {{}\\text{R{{\\text{e}}2}}} -ReS2H2 structure which is formed by breaking the Re4 clusters into separated Re2 dimers, is an indirect-gap semiconductor. Furthermore, mechanical properties of the 1T {{}\\text{R{{\\text{e}}2}}} phase in terms of elastic constants, in-plane stiffness (C) and Poisson ratio (ν) are investigated. It is found that full hydrogenation not only enhances the flexibility of the single layer ReS2 crystal but also increases anisotropy of the elastic constants.

    One major element of EU's external energy policy is expanding its energy norms and regulations to neighbourhood countries and beyond to achieve its energy policy priorities - safe, secure, affordable and sustainable energy supply. The importance of external energy policy has been acknowledged in the European Union's 2007 'energy package', and Second Strategic Energy Review and the European Commission's Communication on security of energy supply and international cooperation. The EU Renewable Energy Directive provides another element to crossborder cooperation by allowing Member States to fulfil their 2020 renewable energy (RES) targets by implementing joint projects in third countries. Even though the Member States' national renewable energy action plans (NREAPs) to reach their RES targets do not indicate any significant use of this mechanism, the RES Directive acknowledges the importance of renewable energy as part of external energy policy. This report aims at presenting the political framework between the EU and the BETTER project target regions (North Africa, Western Balkans and Turkey) with regards to (renewable) energy and the relevant initiatives and the projects to set the scene for RES joint projects as defined in Article 9 of the RES Directive. The main objectives of this study report are (1) to review energy treaties, agreements, and partnerships to assess their relevance to cooperation mechanism with Third countries; and (2) to analyse the relevance of the recent projects and initiatives to BETTER project and improve and trigger the communication and synergies between BETTER project partners and the relevant projects.

  8. Adaptive Fuzzy Control for Power-Frequency Characteristic Regulation in High-RES Power Systems

    Directory of Open Access Journals (Sweden)

    Evangelos Rikos

    2017-07-01

    Full Text Available Future power systems control will require large-scale activation of reserves at distribution level. Despite their high potential, distributed energy resources (DER used for frequency control pose challenges due to unpredictability, grid bottlenecks, etc. To deal with these issues, this study presents a novel strategy of power frequency characteristic dynamic adjustment based on the imbalance state. This way, the concerned operators become aware of the imbalance location but also a more accurate redistribution of responsibilities in terms of reserves activations is achieved. The proposed control is based on the concept of “cells” which are power systems with operating capabilities and responsibilities similar to control areas (CAs, but fostering the use of resources at all voltage levels, particularly distribution grids. Control autonomy of cells allows increased RES hosting. In this study, the power frequency characteristic of a cell is adjusted in real time by means of a fuzzy controller, which curtails part of the reserves, in order to avoid unnecessary deployment throughout a synchronous area, leading to a more localised activation and reducing losses, congestions and reserves exhaustion. Simulation tests in a four-cell reference power system prove that the controller significantly reduces the use of reserves without compromising the overall stability.

  13. Rationales for technology-specific RES support and their relevance for German policy

    2017-01-01

    In order to achieve cost-effective RES-E deployment it is often argued that technology-neutral support schemes for renewables are indispensable. Against this background, RES-E support policies making widely use of technology differentiation in remuneration settings, e.g. across the EU, are frequently criticized from a theoretical point of view. However, in this paper we provide a systematic critique of the technology neutrality concept as a foundation for designing policy support schemes in the RES-E technology field. Specifically, the main objective of the paper is to scrutinize the arguments for technology-neutrality, and discuss three conceptual arguments for why technology-specific support schemes could in fact help minimize the societal costs of reaching future RES-E targets. We also briefly address different political economy concerns, which could constrain the choice of cost-effective policy support schemes, and that have to be taken into account for economic policy advice. For empirical illustration of the key arguments we refer to the case of German RES-E policy-making. The central conclusion from this paper is that technology-specific RES-E support schemes may generate significant economic benefits, particularly if technology markets work imperfectly and in second-best policy settings with additional non-internalized market failures. - Highlights: • Three theoretical cost-effectiveness reasons for technology-specific RES-E support. • German case study to show relevance of theoretical arguments for policy-making. • Political economy constraints to technology-neutral support are demonstrated. • Technology-specific RES-E support may generate significant economic benefits.

    A tight mask seal is frequently difficult to obtain and maintain during single-rescuer bag-valve-mask (BVM) ventilation. The ResMed mask (Bella Vista, NSW, Australia) is a continuous-positive-airway-pressure mask (CM) designed for noninvasive ventilation. In this study, we compared the ventilation performances of a standard mask (SM) and a ResMed CM using a simulation manikin in an out-of-hospital single-rescuer BVM ventilation scenario. Thirty emergency medical technicians (EMTs) performed two 2-minute attempts to ventilate a simulation manikin using BVM ventilation, alternatively, with the SM or the ResMed CM in a randomized order. Ventilation parameters including tidal volume and peak airway pressure were measured using computer analysis software connected to the simulation manikin. Successful volume delivery was defined as delivery of 440-540 mL of tidal volume in accord with present cardiopulmonary resuscitation guidelines. BVM ventilation using the ResMed CM produced higher mean (± standard deviation) tidal volumes (452 ± 50 mL vs. 394 ± 113 mL, p = 0.014) and had a higher proportion of successful volume deliveries (65.3% vs. 26.7%, p < 0.001) than that using the SM. Peak airway pressure was higher in BVM ventilation using the ResMed CM (p = 0.035). Stomach insufflation did not occur during either method. Twenty-nine of the participants (96.7%) preferred BVM ventilation using the ResMed CM. BVM ventilations using ResMed CM resulted in a significantly higher proportion of successful volume deliveries meeting the currently recommended range of tidal volume. Clinical studies are needed to determine the value of the ResMed CM for BVM ventilation.

A caracterização dos resíduos foi determinada utilizando-se a microscopia eletrônica de varredura e espectroscopia na região do infravermelho a qual indicou a presença de grupos carboxílicos, hidroxila e carbonila. O tempo necessário para que o sistema atingisse o equilíbrio para ambos os resíduos foi de 240 min, seguindo uma cinética descrita pelo modelo de pseudo-segunda ordem. A capacidade máxima de adsorção foi de 102,8 mg g-1 para o resíduo da palha de milho, seguindo o modelo de isoterma de Langmuir e 50,9 mg g-1 para o resíduo de palmito pupunha, sendo que o modelo que melhor se ajusta foi Freundlich. Desta forma, esses resíduos são promissores para a adsorção do corante azul de metileno em efluentes.

  1. Revisiting long-run relations in power markets with high RES penetration

    Electricity generation from renewable energy resources (RES) has become increasingly significant to reach EU and emissions reduction targets. At the same time, one of the main EU policy goals has been the creation of a common internal energy market for Europe. In this paper, we focus on these two issues previously studied separately, considering their possible interactions. We first analyze the long-run relationship between day-ahead electricity prices and fuel prices (natural gas and coal) looking at two samples of years characterized by low and high RES penetration, then we explore the integration of EU markets. We show that the electricity–fuel nexus found over 2006–2008 changed dramatically over 2010–2014 for the majority of countries considered. In particular, the long-run dependence of electricity from gas and coal prices is much lower in recent years. Furthermore, our results confirm that the considered EU countries are becoming less integrated as RES-E increases. Our findings suggest that nationally implemented policies to support renewables are successful in increasing RES penetration, but they have lessened the linkage among EU markets, then making integration more difficult to obtain. - Highlights: •RES lower the intra-daily electricity dependence from coal and natural gas. •RES affect the EU wholesale electricity market integration, studied at hourly level. •Overlapping national and supranational policies tackle the achievement of EU targets. •Strong policy coordination is required to avoid that the “greens” promote the “dirtiest”.

    The purpose of this study was to determine the mastery of Content Representation (CoRes) teachers related to the integration of technology and pedagogy in teaching Biology (TPACK). This research uses a descriptive method. The data were taken using instruments CoRes as the primary data and semi-structured interviews as supporting data. The subjects were biology teacher in class X MIA from four schools in Bandung. Teachers raised CoRes was analyzed using a scoring rubric CoRes with coding 1-3 then categorized into a group of upper, middle, or lower. The results showed that the two teachers in the lower category. This results means that the control of teachers in defining the essential concept in the CoRes has not been detailed and specific. Meanwhile, two other teachers were in the middle category. This means that the ability of teachers to determine the essential concepts in the CoRes are still inadequate so that still needs to be improved.

    In this paper, we present the formation of large-size rhenium disulfide (ReS2) films via the sulfurization of Re films deposited on sapphire substrates. The effects of sulfurization temperature and pressure on the crystal quality were investigated. A [001]-oriented single crystal of ReS2 films with 6 × 10 mm2 area was realized. By sulfurizing Re films at 1100 °C, ReS2 films with well-defined sharp interfaces to c-plane sapphire substrates could be formed. Below and above the sulfurization temperature of 1100 °C, incomplete sulfurization and film degradation were observed. The twofold symmetry of the monocrystalline in-plane structure composed of Re-Re bonds along with Re-S bonds pointed to a distorted 1T structure, indicating that this structure is the most stable atomic arrangement for ReS2. For a S/Re compositional ratio equal to or slightly lower than 2.0, characteristic Raman vibrational modes with the narrowest line widths were observed. The typical absorption peak of ReS2 can be detected at 1.5 eV.

    experience with Fidelity120. Another three subjects exhibited initial decrements in spectral cue perception with Fidelity120 at the 8-wk time point; however, evidence from one subject suggested that such decrements may resolve with additional experience. Place-pitch thresholds were inversely related to improvements in vowel F2 frequency perception with Fidelity120 relative to HiRes. However, no relationship was observed between place-pitch thresholds and the other spectral measures (vowel F1 frequency or consonant place of articulation). Findings suggest that Fidelity120 supports small improvements in the perception of spectral speech cues in some Advanced Bionics CI users; however, many users show no clear benefit. Benefits are more likely to occur for vowel spectral cues (related to F1 and F2 frequency) than for consonant spectral cues (related to place of articulation). There was an inconsistent relationship between place-pitch sensitivity and improvements in spectral cue perception with Fidelity120 relative to HiRes. This may partly reflect the small number of sites at which place-pitch thresholds were measured. Contrary to some previous reports, there was no clear evidence that Fidelity120 supports improved sentence recognition in noise.

  8. The Theos/ComRes survey into public perception of Darwinism in the UK: a recipe for confusion.

    Science.gov (United States)

    Baker, Sylvia

    2012-04-01

    A survey of the general public in the UK, conducted in 2008, suggested that more than half of the British population are unconvinced by Darwinism. That survey, conducted by the polling company ComRes on behalf of the theological think-tank Theos, reported its full findings in March 2009 and found them to be "complex and confused." This paper argues that the confusion identified may have been partly engendered by the way in which the survey questionnaire was constructed and that the survey itself, not simply its respondents, was confused. A source of the confusion, it is argued, could be found, first, in the definitions used for the four positions of young earth creationism, theistic evolution, atheistic evolution and intelligent design. Second, a failure to define the key terms "evolution" and "science," used in some of the survey questions, resulted in responses that were difficult to interpret.

    The transition-metal dichalcogenides ReX sub 2 (X = S or Se) and TcS sub 2 with a d sup 3 electron configuration have distorted CdCl sub 2 and Cd(OH) sub 2 structures, respectively, with the Re(Tc) atoms in each layer forming parallelogram-shaped connected clusters (diamond chain). Ab-initio band-structure calculations were performed for ReX sub 2 and TcS sub 2 , and the hypothetical undistorted 1T-TcS sub 2 and 3R-ReX sub 2 structures. The calculations show that ReS sub 2 , ReSe sub 2 and TcS sub 2 are semiconductors with energy gaps of about 1.0 eV, 0.5 eV and 0.7 eV, respectively, while for the undistorted structures the Fermi level is in the partly filled band of d sub x sub sup 2 sub - sub y sub sup 2 and d sub x sub y orbitals of the t sub 2 sub g manifold. X-ray photoemission spectra for the core levels and valence band of ReSe sub 2 and ReS sub 2 are presented.

    2D transition metal dichalcogenides materials are explored as potential surface-enhanced Raman spectroscopy substrates. Herein, a systematic study of the Raman enhancement mechanism on distorted 1T (1T') rhenium disulfide (ReS 2 ) nanosheets is demonstrated. Combined Raman and photoluminescence studies with the introduction of an Al 2 O 3 dielectric layer unambiguously reveal that Raman enhancement on ReS 2 materials is from a charge transfer process rather than from an energy transfer process, and Raman enhancement is inversely proportional while the photoluminescence quenching effect is proportional to the layer number (thickness) of ReS 2 nanosheets. On monolayer ReS 2 film, a strong resonance-enhanced Raman scattering effect dependent on the laser excitation energy is detected, and a detection limit as low as 10 -9 m can be reached from the studied dye molecules such as rhodamine 6G and methylene blue. Such a high enhancement factor achieved through enhanced charge interaction between target molecule and substrate suggests that with careful consideration of the layer-number-dependent feature and excitation-energy-related resonance effect, ReS 2 is a promising Raman enhancement platform for sensing applications. © 2018 WILEY-VCH Verlag GmbH & Co.

    In this paper, we perform a systematic and rigorous study to evaluate the Ohmic nature of the top-contact formed by the monolayer ReS 2 (mReS 2 ) and metals (gold, silver, platinum, nickel, titanium, and scandium) by means of first-principles density functional theory calculations. We investigate the potential barrier, charge transfer and atomic orbital overlap at the mReS 2 -metal interface in consideration of van der Waals forces to understand how efficiently carriers could be injected from the metal contact to the mReS 2 channel. ReS 2 is physisorbed on Au and Ag, which leads to little perturbation of its electronic structures and forms a larger Schottky contact and a higher tunnel barrier at the interface. ReS 2 is chemisorbed on Ti and Sc, where the bonding strongly perturbs the electronic structures and is found to be purely Ohmic. The bonding of ReS 2 on Pt and Ni lies between these two extreme cases, demonstrating an intermediate behavior. These findings not only provide an insight into the mReS 2 -metal interfaces but may also prove to be instrumental in the future design of ReS 2 -based devices with good performance.

  12. Índice de adequação do gerenciamento de resíduos sólidos urbanos como ferramenta para o planejamento: aplicação no estado de São Paulo

    Full Text Available RESUMO: Considerando as diretrizes de gestão e gerenciamento da Política Nacional dos Resíduos Sólidos e a necessidade de uma visão ampla da problemática dos resíduos sólidos urbanos, este artigo propôs uma metodologia qualitativa de análise regional dos resíduos sólidos urbanos, baseada em um índice aplicado como ferramenta de planejamento. Apresentou-se, também, um panorama dos resíduos sólidos urbanos gerados no estado de São Paulo. Para o desenvolvimento do método, foram usados dados de geração de resíduos, população e desenvolvimento humano. Planilhas de cálculo e sistema de informações geográficas foram empregadas como ferramentas. Um índice de adequação do gerenciamento dos resíduos sólidos urbanos foi gerado a partir da atribuição de pesos para variáveis de população, geração de resíduos sólidos urbanos, coleta seletiva e dos resíduos de serviço de saúde e participação em consórcios intermunicipais. Foi obtida uma equação para estimativa da geração de resíduos sólidos urbanos em função da população do estado de São Paulo, com R²=0,9977. O índice de adequação do gerenciamento dos resíduos sólidos urbanos não apresentou tendência espacial, mas possibilitou identificar municípios com maiores problemas na gestão de resíduos sólidos urbanos. Uma análise dos aterros regionais foi realizada, os quais, em sua maioria, estão localizados próximos aos municípios de maior porte do estado de São Paulo. Existe necessidade de aumentar a quantidade de aterros regionais próximos aos municípios de menor porte da parte Oeste do estado. A metodologia do índice de adequação do gerenciamento dos resíduos sólidos urbanos se mostrou adequada para uma análise regional da problemática de resíduos, podendo ser adaptada para outras áreas de estudo, em regiões administrativas diversificadas. Não foi encontrada correlação entre os dados de geração e de desenvolvimento humano.

    In this study, a direct sulfidation reaction of ammonium perrhenate (NH4ReO4) leading to a synthesis of rhenium disulfide (ReS2) is demonstrated. These findings reveal the first example of a simplistic bottom-up approach to the chemical synthesis of crystalline ReS2. The reaction presented here takes place at room temperature, in an ambient and solvent-free environment and without the necessity of a catalyst. The atomic composition and structure of the as-synthesized product were characterized using several analysis techniques including energy dispersive x-ray spectroscopy, x-ray photoelectron spectroscopy, x-ray diffraction, transmission electron microscopy, Raman spectroscopy, thermogravimetric analysis and differential scanning calorimetry. The results indicated the formation of a lower symmetry (1Tʹ) ReS2 with a low degree of layer stacking.

    Highlights: • The ReS_2/rGO composites have been synthesized by a facile one-pot method. • The ReS_2/rGO composites exhibit hierarchical architecture. • The ReS_2/rGO composites deliver better electrochemical performances than ReS_2. • The enhanced performance is due to porous and conductive structure of ReS_2/rGO. - Abstract: Rhenium disulfide (ReS_2), a two-dimensional (2D) semiconductor, has attracted more and more attention due to its unique anisotropic electronic, optical, mechanical properties. However, the facile synthesis and electrochemical property of ReS_2 and its composite are still necessary to be researched. In this study, for the first time, the ReS_2/reduced graphene oxide (rGO) composites have been synthesized through a facile and one-pot hydrothermal method. The ReS_2/rGO composites exhibit a hierarchical, interconnected, and porous architecture constructed by nanosheets. As anode for lithium-ion batteries, the as-synthesized ReS_2/rGO composites deliver a large initial capacity of 918 mAh g"−"1 at 0.2 C. In addition, the ReS_2/rGO composites exhibit much better electrochemical cycling stability and rate capability than that of bare ReS_2. The significant enhancement in electrochemical property can be attributed to its unique architecture constructed by nanosheets and porous structure, which can allow for easy electrolyte infiltration, efficient electron transfer, and ionic diffusion. Furthermore, the graphene with high electronic conductivity can provide good conductive passageways. The facile synthesis approach can be extended to prepare other 2D transition metal dichalcogenides semiconductors for energy storage and catalytic application.

  18. Revisiting support policies for RES-E adulthood: Towards market compatible schemes

    International Nuclear Information System (INIS)

    Huntington, Samuel C.; Rodilla, Pablo; Herrero, Ignacio; Batlle, Carlos

    2017-01-01

    The past two decades of growth in renewable energy sources of electricity (RES-E) have been largely driven by out-of-market support policies. These schemes were designed to drive deployment on the basis of specific subsidies sustained in time to allow for the larger costs as well as to limit investor risk. While these policies have proven to be effective, the way they have been designed to date has led to costly market distortions that are becoming more difficult to ignore as penetrations reach unpreceded levels. In the context of this growing concern, we provide a critical analysis of the design elements of RES-E support schemes, focusing on how they affect this trade-off between promoting and efficiently integrating RES-E. The emphasis is on the structure of the incentive payment, which in the end turns to be the cornerstone for an efficient integration. We conclude that, while needed, a well-designed and further developed capacity-based support mechanism complemented with ex-post compensations defined for reference benchmark plants, such as the mechanism currently implemented in Spain, is an alternative with good properties if the major goal is truly market integration. The approach is robust to future developments in technology cost, performance and market penetration of RES-E. - Highlights: • Market distortions due to RES support mechanisms are becoming difficult to ignore. • This paper provides a critical analysis of the design elements of RES support schemes. • The emphasis is on the structure of the incentive, key for an efficient integration. • We argue in favor of a further developed capacity-based support mechanism. • The incentive should be combined with the design of a set of reference plants.

  1. Energy and climate hand-in-hand: Financing RES-E support with carbon revenues

    International Nuclear Information System (INIS)

    Verde, Stefano F.; Pazienza, Maria Grazia

    2016-01-01

    In Italy, the cost of support for renewable electricity (RES-E) is largely recovered through the “A3 surcharge”, which weighs heavily on electricity bills. Using household survey data, we show the A3 surcharge is markedly regressive. Carbon taxation in the non-ETS sector is envisaged as a means to reduce CO_2 emissions cost-effectively and generate revenue to lower the A3 surcharge. A non-ETS carbon tax would be less regressive than the A3 surcharge and its cost would be more evenly distributed across households. We calculate the revenue of a €20/tCO_2 non-ETS carbon tax would have allowed a cut in the A3 surcharge of about 68% in 2011, and 39% in 2012. The impact of the carbon tax plus the reduced A3 surcharge would have been less regressive, but the cost higher for most households. The restrictions imposed in the simulations mean the results are only appropriate to render first-round effects of the reform. Policy relevance: In the vast majority of the EU Member States, the cost of RES-E support is largely paid by electricity consumers, most often through specific surcharges. Rising electricity prices are a common concern given the implications for competitiveness and equity. The Member States facing this issue could conveniently address it through environmental tax reforms consistent with the Climate and Energy Package. Replacing RES-E surcharges with carbon taxes in the non-ETS sector would permit cost-effective reduction of CO_2 emissions while allocating the cost of RES-E support more equitably. The difference in regressivity would stem from the different consumption patterns of home fuels (including electricity) and motor fuels across income distribution. A cross-country comparison of energy household budget shares proves the structural nature of this difference between home fuels and motor fuels. Moreover, the notion that electricity consumers should pay for RES-E support is questioned on the grounds that electricity is a basic necessity good and RES

  3. Costs and risks of the import of RES statistics by the Dutch government

    Energy Technology Data Exchange (ETDEWEB)

    2012-11-15

    This paper presents a first estimate of the costs and risks of a potential import of renewable energy statistics by the Dutch Government in order to meet the binding renewable energy (RE) target of 14% by 2020. Recently, the new government has announced that it will increase the ambition from 14% to 16%. Progress so-far has been slow however and meeting these targets requires near to maximum realisable deployment rates of all relevant technologies. It points at the necessity to increase national policy measures (spatial, political, financial, etc.) for all renewable energy technologies or alternatively, to apply the cooperation mechanisms and/or import RES statistics from other countries. It is generally assumed that imported RE statistics, through the cooperation mechanisms of the European RES Directive, will have lower costs than supporting the potentially more expensive domestic technologies that would be needed to meet the targets fully by domestic production. This paper shows that this assumption is questionable, and that the risks of pursuing an import-strategy may be significant. The analysis shows that the use of statistical transfers, which in principle may be a viable option for realising part of the Dutch RE target, is linked to high uncertainties. Important aspects contributing to these uncertainties are: The effectiveness and efficiency of policies in the European Member States to meet domestic RE targets by and up to 2020, and hence the related surplus/shortfall of RE production and resulting market prices for statistical transfers; The price setting mechanisms that will be established between Member States, including the anticipated cost of infringement in case of non-fulfilment of the 2020 targets. Imports will likely be charged against the market prices for (statistical) transfers, not against the cost prices of RE technologies. The price of statistical transfers can be expected to be higher in the case of a clear 'buyer market' in which

    Most of the world activity on research, development and control of polymer durability is still based on empirical techniques developed in the early ages of polymer uses. Those techniques should be critically analysed considering the state of the art in the fundamental understanding of these complex phenomena. A more rational approach is described, especially to predict the lifetime of polymeric materials in environmental conditions. That approach is based on the recognition of the chemical evolution mechanisms. Les activités de recherche, développement et contrôle de durabilité des matériaux polymères sont encore, pour une part très importante, basées sur l'emploi de techniques empiriques dont les principes ont été énoncés dès le début de l'exploitation de ces matériaux. Une analyse critique de ces méthodes s'impose aujourd'hui en tenant compte de l'avancement des connaissances. Une approche plus rationnelle est décrite, approche basée sur la reconnaissance des mécanismes d'évolution chimique. A titre d'exemple, le mécanisme d'évolution du PVC sous contraintes conjuguées de l'UV, de la chaleur et de l'oxygène, est décrit. Des études récentes de photooxydation de polymères conducteurs au sein de polyéthylène sont également succinctement rapportées.

    Rhenium disulfide (ReS2) is a unique semiconducting TMD with distorted 1T structure and weak interlayer coupling. We have previously investigated its in-plane anisotropic property and electronic applications on FET and digital inverters. In this talk, we will present high responsivity phototransistors based on few-layer ReS2. Depending on the back gate voltage, source drain bias and incident optical light intensity, the maximum attainable photoresponsivity can reach as high as 88,600 A W-1, which is one of the highest value among individual two-dimensional materials with similar device structures. Such high photoresponsivity is attributed to the increased light absorption as well as the gain enhancement due to the existence of trap states in the few-layer ReS2 flakes. The existence of trap states is proved by temperature dependent transport measurements. It further enables the detection of weak signals. Our studies underscore ReS2 as a promising material for future electronic and sensitive optoelectronic applications.

    Barth, Ruediger; Weber, Christoph; Swider, Derk J.

    2008-01-01

    This article focuses on the distribution of costs induced by the integration of electricity generation from renewable energy sources (RES-E). The treatment to distribute these costs on different market actors is crucial for its development. For this purpose, individual actors of electricity markets and several cost categories are identified. According to the defined cost structure, possible treatments to distribute the individual cost categories on different relevant actors are described. Finally, an evaluation of the cost distribution treatments based on an economic analysis is given. Economic efficiency recommends that clearly attributable (shallow) grid connection as well as (deep) grid costs are charged to the corresponding RES-E producer and that the RES-E producers are also charged the regulating power costs. However, deep grid integration costs should be updated to reflect evolving scarcities. Also regulating power costs should reflect actual scarcity and thus be symmetric and based on real-time prices, taking into account the overall system imbalance. Moreover, the time span between the closure of the spot market and actual delivery should be chosen as short as possible to enable accurate RES-E production forecasts

    Parity violating electron scattering has become a well established tool which has been used, for example, to probe the Standard Model and the strange-quark contribution to the nucleon. While much of this work has focused on elastic scattering, the RES-Parity experiment, which has been proposed to take place at Jefferson Laboratory, would focus on inelastic scattering in the low-Q 2 , low-W domain. RES-Parity would search for evidence of quark-hadron duality and resonance structure with parity violation in the resonance region. In terms of parity violation, this region is essentially unexplored, but the interpretation of other high-precision electron scattering experiments will rely on a reasonable understanding of scattering at lower energy and low-W through the effects of radiative corrections. RES-Parity would also study nuclear effects with the weak current. Because of the intrinsic broad band energy spectrum of neutrino beams, neutrino experiments are necessarily dependent on an untested, implicit assumption that these effects are identical to electromagnetic nuclear effects. RES-Parity is a relatively straight forward experiment. With a large expected asymmetry (∼ 0.5 x 10 -4 ) these studies may be completed with in a relatively brief period

  20. Cicero and the Mixed Constitution (res publica mixta

    Directory of Open Access Journals (Sweden)

    Mitja Sadek

    2009-12-01

    Full Text Available The story of the mixed constitution is the story of the most stable and just constitution. In theory, this is a combination of at least two of the three elementary forms of government (monarchy, aristocracy and democracy, with some advantages that elementary forms may lack. It originated with the deliberation of Greek philosophers, who wanted to draw up a constitution safeguarding against the permanent variation of elementary constitutional forms and against coups d’état. For both Plato and Aristotle, the mixed constitution was, above all, the reflection of a search for balance between the two extreme forms of government, direct (Athenian democracy on the one hand and the exclusion of the people from governing on the other. The Greek theory was applied by the historian Polybius to the traditional tripartite constitution of the Roman republic. In his view, the consuls were monarchic elements, the senate an aristocratic element, and the comitia a democratic one. Cicero’s introduction of the idea of the mixed constitution in De re publica can only be understood in the light of the author’s personal situation and contemporary political circumstances. His political engagement at a time when the republic was gradually transforming into a monarchy aimed at restoring the important role of the nobility, represented by the senate. For Cicero, the mixed constitution was mainly an instrument for restoring the lost balance between the consuls, the senate, and the comitia, a last chance to save the decaying republic. The concluding part of the article addresses Alois Riklin’s recent discussion of the modern reception of the mixed constitution idea, which advances the controversial thesis that the paradigm of power division, the foundation of modern representative democracy, originates directly from the mixed constitution.

Between Saint-Pierre-sur-Dives and Livarot, many hâloirs or cheese maturing rooms attest the importance of that bygone and often poorly documented agricultural production. A mere architectural examination of these buildings allows us nevertheless to determine which kind of cheese had been matured in which building. It gives us also a whole new perspective on the commonly received principles about the arrangement of the buildings, especially the setting of their apertures, and points the fact that the technical prescriptions from the 19th century that have been spread through the scientific societies have had no follow-up.

Objetivou-se estudar o processo de fermentação semissólida do resíduo de abacaxi, utilizando a levedura Saccharomyces cerevisiae, com 10% de inoculo e avaliando o efeito da concentração inicial da levedura, assim como o tempo de fermentação sobre o teor proteico. O processo foi acondicionado em estufa de circulação de ar forçada a 55 °C, durante 48 horas, sendo feita pesagens nos intervalos de 0, 14, 18, 24, 38, 42 e 48 h e realizadas analises físico-químicas e granulométrica. Mediante os resultados, observou-se uma diminuição da umidade com o passar do tempo chegando a atingir 0,91% ao final do estudo, já o teor proteico, aumentou consideravelmente, com proteína bruta de 14% para 20,56%, após 48 h, o teor de sólidos solúveis totais apresentou um declínio possivelmente devido o consumo de carboidratos pela levedura. Foi realizada a análise granulométrica do resíduo, onde se observou que cerca de 80% das partículas apresentaram diâmetro maior que 2,4 milímetros. Através da fermentação semissólida dos resíduos de abacaxi foi possível elevar o teor proteico e aumentar a concentração de nutrientes, transformando um rejeito em um possível produto para destino humano ou animal com alto valor agregado.Protein enrichment of pineapple residue by semisolid fermentationAbstract: The fermentation in state semissólido executes an important paper in the use of solid residues, due to the synthesis of different compounds, which great interest is turned for industrial segments.

    Given the mentioned circumstances, conventional energy planning in the Canary Islands is a very complex task. The Regional Energy Plan PECAN (2007-2015) tries to correct the existing critical situation setting, among others, the ambitious goal of >25% electricity from RES (mostly wind) for 2015. In parallel to this conventional energy planning, outstanding initiatives in the distributed generation field are underway. ITC vision is that the Canarian Archipelago, given its particular characteristics (insular systems of different sizes, abundant RES potential -different sources-, important natural and biodiversity heritage, etc.), are a laboratory for testing and demonstrating new energy technologies in real conditions, as well as their commercial implementation. These new technologies include energy storage (particularly for excess RES that cannot be absorbed by the grids), development of 100% energy self- sufficiency models (with exclusive use of RES) and micro-/minigrids with high RES penetration and RES forecasting, including advanced ICTs and sustainable mobility concepts (e.g. V2G technologies). Given the high conventional generation costs and the relatively low RES costs (wind electricity production cost is less than 0.03 Euro/kWh), the Canary Islands could in the short term achieve grid parity, and in this sense pioneer the change to a RES based energy system. Models tested on the islands could be exported or extrapolated to our islands, regions of developing countries and even other regions in continental Europe. (orig.)

    Fertile soils are a fundamental resource for the production of biomass and provision of food and energy. A growing world population and latest climate targets lead to an increasing demand for bio-based products which require preserving and - ideally - improving the long-term productivity of soils as a bio-economic resource. At the same time, other soil functions and ecosystem services need to be maintained: filter for clean water, carbon sequestration, provision and recycling of nutrients, and habitat for biological activity. All these soil functions result from the interaction of a multitude of physical, chemical and biological processes which are insufficiently understood. In addition, we lack understanding about the interplay between the socio-economic system and the soil system and how soil functions benefit human wellbeing, including SDGs. However, a solid and integrated assessment of soil quality requires the consideration of the ensemble of soil functions and its relation to soil management. To make soil management sustainable, we need to establish a scientific knowledge base of complex soil system processes that allows for developing models and tools to quantitatively predict the impact of a multitude of management measures on soil functions. This will finally allow for the provision of options for a site-specific, sustainable soil management. To face this challenge, the German Federal Ministry of Education and Research (BMBF) recently launched the funding program "Soil as a Sustainable Resource for the Bioeconomy - BonaRes". In a joint effort, ten collaborative projects and the coordinating BonaRes Centre are engaged to close existing knowledge gaps for a profound and systemic assessment and understanding of soil functions and their sensitivity to soil management. In BonaRes, the complete process chain of sustainable soil use in the context of a sustainable bio-economy is being addressed: from understanding of soil processes using state-of the art and

    2017-09-29

    The ResStock analysis tool is helping states, municipalities, utilities, and manufacturers identify which home upgrades save the most energy and money. Across the country there's a vast diversity in the age, size, construction practices, installed equipment, appliances, and resident behavior of the housing stock, not to mention the range of climates. These variations have hindered the accuracy of predicting savings for existing homes. Researchers at the National Renewable Energy Laboratory (NREL) developed ResStock. It's a versatile tool that takes a new approach to large-scale residential energy analysis by combining: large public and private data sources, statistical sampling, detailed subhourly building simulations, high-performance computing. This combination achieves unprecedented granularity and most importantly - accuracy - in modeling the diversity of the single-family housing stock.

    Full Text Available O objetivo deste trabalho foi utilizar um resíduo de serragem de granito, proveniente da indústria de pedras ornamentais do estado do Espírito Santo, como aditivo na fabricação de produtos cerâmicos para construção civil. Este resíduo é um material não biodegradável que quando descartado gera poluição e degrada o meio ambiente. Assim, uma amostra deste material foi selecionada de modo que suas características com respeito a composição química, difração de raios X, análise de tamanho de partícula, massa específica real e plasticidade pudessem ser estudadas. Foram preparadas misturas contendo até 10% em peso de resíduo, e sinterizadas em sete diferentes temperaturas entre 850 ºC e 1150 ºC. A evolução na formação de fases cristalinas nos corpos cerâmicos durante a sinterização foi acompanhada por DRX. As propriedades físico-mecânicas foram determinadas em função da temperatura de sinterização e % de resíduo adicionado. Os resultados revelaram que o resíduo é um material polimineral não plástico constituído basicamente por sílica, feldspatos, mica e calcita. Uma série de transformações de fases ocorreram durante a sinterização. Além do mais, os corpos sinterizados contendo resíduo de serragem de granito têm uso provável em cerâmica vermelha, contribuindo para a minimização de resíduos e desenvolvimento auto-sustentado.

    Full Text Available OBJETIVO: Verificar o processo de gerenciamento dos resíduos odontológicos do serviço público de saúde em 11 municípios brasileiros. MATERIAL E MÉTODO: Uma única pesquisadora realizou as visitas e as observações foram anotadas em um roteiro previamente elaborado e testado. RESULTADO: Foram visitadas 50 unidades de saúde, sendo que nenhuma apresentou cópia do plano de gerenciamento de resíduos. Do total de estabelecimentos, 62% realizavam a correta segregação dos resíduos no momento da sua geração. A presença de recipientes adequados a cada tipo de resíduo gerado no consultório odontológico foi observada em 74% dos estabelecimentos e, destes, 94% apresentavam capacidade adequada ao tipo de resíduo gerado. A identificação do tipo de resíduo nas embalagens plásticas bem como anotações identificando o estabelecimento gerador dos resíduos foram encontradas em 8% e 6%, respectivamente. Somente 21% dos estabelecimentos apresentavam locais apropriados, de acordo com as normas vigentes, para o armazenamento dos resíduos até que fosse feita a coleta externa. CONCLUSÃO: Constatou-se na presente pesquisa que a rotina adotada pela rede pública de saúde bucal, no que tange ao gerenciamento de resíduos de saúde, apresentou falhas.

    2004-01-01

    This report documents state-of-the-art methods, tools, and data for the conduct of a fire Probabilistic Risk Assessment (PRA) for a commercial nuclear power plant (NPP) application. The methods have been developed under the Fire Risk Re-quantification Study. This study was conducted as a joint activity between EPRI and the U. S. NRC Office of Nuclear Regulatory Research (RES) under the terms of an EPRI/RES Memorandum of Understanding (RS.1) and an accompanying Fire Research Addendum (RS.2). Industry participants supported demonstration analyses and provided peer review of this methodology. The documented methods are intended to support future applications of Fire PRA, including risk-informed regulatory applications. The documented method reflects state-of-the-art fire risk analysis approaches. The primary objective of the Fire Risk Study was to consolidate recent research and development activities into a single state-of-the-art fire PRA analysis methodology. Methodological issues raised in past fire risk analyses, including the Individual Plant Examination of External Events (IPEEE) fire analyses, have been addressed to the extent allowed by the current state-of-the-art and the overall project scope. Methodological debates were resolved through a consensus process between experts representing both EPRI and RES. The consensus process included a provision whereby each major party (EPRI and RES) could maintain differing technical positions if consensus could not be reached. No cases were encountered where this provision was invoked. While the primary objective of the project was to consolidate existing state-of-the-art methods, in many areas, the newly documented methods represent a significant advancement over previously documented methods. In several areas, this project has, in fact, developed new methods and approaches. Such advances typically relate to areas of past methodological debate.

    2014-01-01

    Scarcity or abundance of energy resources usually depends on physical and geographical conditions in the region. However, the energy flow in the region also depends on the efficient use of energy resources, the consumption rate of energy and the possibility to use local renewable and non-renewable energy resources. Production, distribution and the use of energy resources in the region are the challenges for central and local government, business and social service, customers and other stakeholders. Development of regional energy economy should be optimized according to the available energy flow in the region using a network system analysis method, which provides solutions for developing sustainable energy economy models. The network system analysis method enables to optimize the use of local and renewable resources at the regional level and reveals available local energy resources. An efficient use of available regional resources and the use of renewable energy sources (RES) should be the main goals for the development of regional energy system. RES can compete with traditional fossil fuel with the condition that all hidden aspects are revealed. The network system analysis method enables to indicate energy flows in the region as well as indicate pros and cons of using renewable energy technologies. - Highlights: • RES integration into the regional energy development scenarios is done. • Innovative process network system (PNS) analysis method is used. • PNS method is used to optimize the use of local and renewable resources. • Analysis of energy flow in region using PNS method is done

    TREX1 constitutes the major 3′→5′ DNA exonuclease activity measured in mammalian cells. Recently, biallelic mutations in TREX1 have been shown to cause Aicardi-Goutières syndrome at the AGS1 locus. Interestingly, Aicardi-Goutières syndrome shows overlap with systemic lupus erythematosus at both clinical and pathological levels. Here, we report a heterozygous TREX1 mutation causing familial chilblain lupus. Additionally, we describe a de novo heterozygous mutation, affecting a critical catalytic residue in TREX1, that results in typical Aicardi-Goutières syndrome. PMID:17357087

Néanmoins à partir des systèmes juridiques et des pratiques d’autres pays d’Europe, les arrêts pragmatiques de la Cour européenne des droits de l'homme révèlent une retenue comparable, même si leur fondement est nécessairement différent.Dans son ensemble, la jurisprudence de la Cour permet de constater que les Etats membres du Conseil de l’Europe ont parfois à l’égard de la prière des attitudes restrictives qui dépendent soit d’une sorte de protection de la religion dominante par rapport aux cultes minoritaires, soit d’un refus implicite de l’athéisme. En revanche, la notion de service public, n’étant pas universellement reconnue en Europe, ne fournit pas un cadre de raisonnement juridique signifiant dans les arrêts, ce qui ne permet d’identifier les rapports entre prières et service public que par le biais du contexte dans lequel se produisent les actes de prière.The mark of the separation between the Church and the State seems sufficiently strong in France so that the points of contact between the civil service and prayer are rare and rather indirect, starting with behaviours which do not have in general aim to oppose the sole act of prayer to the legal and social standards surrounding (First part.

On rappelle d'abord le modèle du réseau de Flory-Huggins et on en souligne les déficiences. On traite ensuite brièvement de la mécanique statistique des solutions de polymères introduite par Prigogine en 1957 et on montre qu'elle constitue un progrès qualitatif par rapport à la théorie du réseau, mais qu'elle ne prévoit cependant pas de manière quantitative les propriétés de ces solutions. On montre ensuite que le concept de volume libre, qui permet un traitement simplifié de certaines quantités, permet également d'expliquer tout naturellement l'existence d'une deuxième température de séparation en phase lorsque l'on élève la température, propriété qui différencie les solutions de polymères des mélanges de liquidés simples. Enfin, dans une dernière partie, on mentionne brièvement les travaux récents de l'École de Paris, qui traite les solutions de polymères par analogie avec les transitions magnétiques. This article examines différent approaches ta the thermodynamics of polymer solutions set in their historical context. First of all, the Flory-Huggins network model is described and ifs deficiencies are pointed out. Then attention is briefly drawn to the statistical mechanics of polymer solutions as introduced by Prigogine in 1957, and this mechanics is shown to be a qualitative advance compared with the network theory, but it nonetheless does not quantitatively predict the properties of such solutions. It is then shown that the concept of free volume, enabling some quantifies to be treated in a simplified way, also serves to provide a quite natural explanation for the existence of a second phase separation temperature when the temperature is raised, i. e. a property that differentiates polymer solutions from simple liquid mixtures.

    Full Text Available Resumo A produção de água tratada, nas Estações de Tratamento de Água (ETAs gera lodo, também chamado de resíduo de ETA (RETA. A maior parte das ETAs descarrega estes resíduos em meios hídricos, apesar da política nacional de resíduos sólidos salientar que é de responsabilidade da fonte geradora adotar destinação sustentável aos resíduos, visto que o seu lançamento in natura nos corpos hídricos é prejudicial, tornando esse meio de disposição um sério passivo ambiental das companhias de saneamento. O objetivo do presente trabalho foi realizar a caracterização física do resíduo gerado em uma ETA buscando obter parâmetros com bases normativas e considerar alternativas sustentáveis de reincorporação do lodo na cadeia produtiva para confecção de materiais de construção, de maneira a reduzir o impacto causado com o lançamento do RETA nos cursos de água. Para isso, foram realizados ensaios de índices de consistência do resíduo, granulometria, microscopia de varredura eletrônica e espectroscopia por dispersão de energia. Os resultados encontrados nas análises do resíduo demonstram a potencialidade de sua aplicação em substituição parcial do solo e/ou da areia, sendo suas propriedades similares a matéria-prima, na fabricação de materiais de construção.

    Highlights: • Guidelines for power utilities to reach specific decarbonisation targets offered. • Optimization model of RES share to be introduced into power system is proposed. • Single criteria analysis and multicriteria sustainability assessment are applied. • The optimization method has been demonstrated on a real power system. • In the considered case, HIGH RES scenario showed to be the preferable one. - Abstract: This paper provides guidelines and principles for power utilities to reach specific energy and decarbonisation targets. Method of power generation portfolio optimization, as function of sustainability and decarbonisation, along with appropriate criteria, has been proposed. Application of this optimization method has been demonstrated on a real power system – power utility JP Elektroprivreda BiH d.d. – Sarajevo (EPBiH), a typical example of South East European power system. The software tool WASP IV has been employed in the analysis, in order to define the dynamics and an optimized expansion of generation portfolio of the power system under consideration for the next period. The mid-term generation portfolio development plan for the EPBiH power system until year 2030 has been made during this research, taking into account the shutdown dynamics of existing power units and commissioning new ones, in order to provide safe supply of electric and heat energy for local consumers. Three basic scenario of renewable energy sources (RES) expansion have been analysed to reach specific RES and decarbonisation targets set for 2030, including RES share increase from the current level of 18% up to 35% (LOW RES), 45% (MID RES) and 55% (HIGH RES). Effects to the sustainability are considered through environmental, economic and social indicators. Multicriteria sustainability assessment gave an advantage to the HIGH RES, under assumption of equal weighting factors of economic and environment groups of indicators. Also, single criteria analysis has been

    Substitutional doping of transition metal dichalcogenide two-dimensional materials has proven to be effective in tuning their intrinsic properties, such as band gap, transport characteristics, and magnetism. In this study, we realized substitutional doping of monolayer rhenium disulfide (ReS 2 ) with Mo via chemical vapor deposition. Scanning transmission electron microscopy demonstrated that Mo atoms are successfully doped into ReS 2 by substitutionally replacing Re atoms in the lattice. Electrical measurements revealed the degenerate p-type semiconductor behavior of Mo-doped ReS 2 field effect transistors, in agreement with density functional theory calculations. The p-n diode device based on a doped ReS 2 and ReS 2 homojunction exhibited gate-tunable current rectification behaviors, and the maximum rectification ratio could reach up to 150 at V d = -2/+2 V. The successful synthesis of p-type ReS 2 in this study could largely promote its application in novel electronic and optoelectronic devices.

J Strength Cond Res 32(1): 323-329, 2017-This study examined the possibility of using movement velocity and the perceived exertion as indicators of relative load in the bench press (BP) exercise. A total of 308 young, healthy, resistance trained athletes (242 men and 66 women) performed a progressive strength test up to the one repetition maximum for the individual determination of the full load-velocity and load-exertion relationships. Longitudinal regression models were used to predict the relative load from the average velocity (AV) and the OMNI-Resistance Exercise Scales (OMNI-RES 0-10 scale), considering sets as the time-related variable. Load associated with the AV and the OMNI-RES 0-10 scale value expressed after performing a set of 1-3 repetitions were used to construct 2 adjusted predictive equations: Relative load = 107.75 - 62.97 × average velocity; and Relative load = 29.03 + 7.26 × OMNI-RES 0-10 scale value. The 2 models were capable of estimating the relative load with an accuracy of 84 and 93%, respectively. These findings confirm the ability of the 2 calculated regression models, using load-velocity and load-exertion from the OMNI-RES 0-10 scale, to accurately predict strength performance in BP.

    Anisotropic two-dimensional (2D) van der Waals (vdW) layered materials, with both scientific interest and application potential, offer one more dimension than isotropic 2D materials to tune their physical properties. Various physical properties of 2D multi-layer materials are modulated by varying their stacking orders owing to significant interlayer vdW coupling. Multilayer rhenium disulfide (ReS2), a representative anisotropic 2D material, was expected to be randomly stacked and lack interlayer coupling. Here, we demonstrate two stable stacking orders, namely isotropic-like (IS) and anisotropic-like (AI) N layer (NL, N > 1) ReS2 are revealed by ultralow- and high-frequency Raman spectroscopy, photoluminescence and first-principles density functional theory calculation. Two interlayer shear modes are observed in AI-NL-ReS2 while only one shear mode appears in IS-NL-ReS2, suggesting anisotropic- and isotropic-like stacking orders in IS- and AI-NL-ReS2, respectively. This explicit difference in the observed frequencies identifies an unexpected strong interlayer coupling in IS- and AI-NL-ReS2. Quantitatively, the force constants of them are found to be around 55-90% of those of multilayer MoS2. The revealed strong interlayer coupling and polytypism in multi-layer ReS2 may stimulate future studies on engineering physical properties of other anisotropic 2D materials by stacking orders.Anisotropic two-dimensional (2D) van der Waals (vdW) layered materials, with both scientific interest and application potential, offer one more dimension than isotropic 2D materials to tune their physical properties.

    1995-04-01

    Lawrence Livermore National Laboratory developed a space-qualified High Resolution (HiRes) imaging LIDAR (Light Detection And Ranging) system for use on the DoD Clementine mission. The Clementine mission provided more than 1.7 million images of the moon, earth, and stars, including the first ever complete systematic surface mapping of the moon from the ultra-violet to near-infrared spectral regions. This article describes the Clementine HiRes/LIDAR system, discusses design goals and preliminary estimates of on-orbit performance, and summarizes lessons learned in building and using the sensor. The LIDAR receiver system consists of a High Resolution (HiRes) imaging channel which incorporates an intensified multi-spectral visible camera combined with a Laser ranging channel which uses an avalanche photo-diode for laser pulse detection and timing. The receiver was bore sighted to a light-weight McDonnell-Douglas diode-pumped ND:YAG laser transmitter that emmitted 1.06 {micro}m wavelength pulses of 200 mJ/pulse and 10 ns pulse-width, The LIDAR receiver uses a common F/9.5 Cassegrain telescope assembly. The optical path of the telescope is split using a color-separating beamsplitter. The imaging channel incorporates a filter wheel assembly which spectrally selects the light which is imaged onto a custom 12 mm gated image intensifier fiber-optically-coupled into a 384 x 276 pixel frame transfer CCD FPA. The image intensifier was spectrally sensitive over the 0.4 to 0.8 {micro}m wavelength region. The six-position filter wheel contained 4 narrow spectral filters, one broadband and one blocking filter. At periselene (400 km) the HiRes/LIDAR imaged a 2.8 km swath width at 20-meter resolution. The LIDAR function detected differential signal return with a 40-meter range accuracy, with a maximum range capability of 640 km, limited by the bit counter in the range return counting clock.

    Full Text Available O volume de resíduos inorgânicos gerados a cada ano vem crescendo em todo mundo e apresenta um dos maiores problemas da sociedade moderna. Este trabalho tem por objetivo analisar a viabilidade de utilização do resíduo da serragem do granito e de resíduos da construção civil como materiais alternativos para a produção de argamassas. Os resíduos foram caracterizados física e mineralogicamente por meio da determinação de distribuição e tamanho de partículas, massa e área específica, composição química, difração de raios X e análise térmica diferencial. Foi determinado o índice de atividade pozolânica com cal dos resíduos da construção. Foram formuladas composições de argamassas substituindo parcialmente a cal pelos resíduos, e moldados corpos-de-prova. Os corpos-de-prova foram curados por 7, 14, 28 e 60 dias e, em seguida, foi determinada a resistência à compressão simples. Os resíduos apresentam elevados teores de SiO2, Al2O3 e Fe2O3 e possuem as fases cristalinas quartzo, mica, feldspato, carbonato de cálcio e óxido de ferro. A substituição do aglomerante por resíduos na produção de argamassas pode ser efetuada com sucesso em teores de até 50% e os resíduos com atividade pozolânica propiciam aumentos significativos na resistência à compressão simples das argamassas.Around the world the amount of inorganic wastes has increased dramatically and is one of the most important issues for modern society.

  6. Coherent Control of Nanoscale Ballistic Currents in Transition Metal Dichalcogenide ReS2.

    2015-04-28

    Transition metal dichalcogenides are predicted to outperform traditional semiconductors in ballistic devices with nanoscale channel lengths. So far, experimental studies on charge transport in transition metal dichalcogenides are limited to the diffusive regime. Here we show, using ReS2 as an example, all-optical injection, detection, and coherent control of ballistic currents. By utilizing quantum interference between one-photon and two-photon interband transition pathways, ballistic currents are injected in ReS2 thin film samples by a pair of femtosecond laser pulses. We find that the current decays on an ultrafast time scale, resulting in an electron transport of only a fraction of one nanometer. Following the relaxation of the initially injected momentum, backward motion of the electrons for about 1 ps is observed, driven by the Coulomb force from the oppositely moved holes. We also show that the injected current can be controlled by the phase of the laser pulses. These results demonstrate a new platform to study ballistic transport of nonequilibrium carriers in transition metal dichalcogenides.

    The Raman tensor of a crystal is the derivative of its polarizability tensor and is dependent on the symmetries of the crystal and the Raman-active vibrational mode. The intensity of a particular mode is determined by the Raman selection rule, which involves the Raman tensor and the polarization configurations. For anisotropic two-dimensional (2D) layered crystals, polarized Raman scattering has been used to reveal the crystalline orientations. However, due to its complicated Raman tensors and optical birefringence, the polarized Raman scattering of triclinic 2D crystals has not been well studied yet. Herein, we report the anomalous polarized Raman scattering of 2D layered triclinic rhenium disulfide (ReS 2 ) and show a large circular intensity differential (CID) of Raman scattering in ReS 2 of different thicknesses. The origin of CID and the anomalous behavior in polarized Raman scattering were attributed to the appearance of nonzero off-diagonal Raman tensor elements and the phase factor owing to optical birefringence. This can provide a method to identify the vertical orientation of triclinic layered materials. These findings may help to further understand the Raman scattering process in 2D materials of low symmetry and may indicate important applications in chiral recognition by using 2D materials.

This was to be achieved through estimating mean bar velocity of the concentric phase of a bench press using a prediction equation. The values for the prediction equation would be obtained using OMNI-RES scale values of different loads of the bench press exercise. Sixty males ( voluntarily participated in the study and were tested using an incremental protocol on a Smith machine to determine one repetition maximum (1RM in the bench press exercise. A linear regression analysis produced a strong correlation (r = -0.94 between rating of perceived exertion (RPE and mean bar velocity (Velmean. The Pearson correlation analysis between real power output (PotReal and estimated power (PotEst showed a strong correlation coefficient of r = 0.77, significant at a level of p = 0.01. Therefore, the OMNI-RES scale can be used to predict Velmean in the bench press exercise to control the intensity of the exercise. The positive relationship between PotReal and PotEst allowed for the identification of a maximum power-training zone.

    2014-01-01

    Full Text Available The author discusses the effects of the res judicata rule as regards jurisdictional decisions of the International Court of Justice. He finds that there exists a special position of a judgment on preliminary objection in respect to both aspects of the res judicata rule - its binding force and finality. A perception of distinct relativity of a jurisdictional decision of the Court, expressing its interlocatory character pervades, in his opinion, the body of law regulating the Court's activity. Preliminary objections as such do not exhaust objections to the jurisdiction of the Court, as evidenced by non-preliminary objections to the jurisdiction of the Court giving rise to the application of the principle compétence de la compétence understood in the narrow sense. With regard to the binding force of a judgment on preliminary objections, it does not create legal obligations stricto sensu. The author finds that the relative character of jurisdictional decisions of the Court as compared with a judgment on the merits is justified on a number of grounds.

    We demonstrated the fabrication of large-area ReS 2 transistors and logic gates composed of a chemical vapor deposition (CVD)-grown multilayer ReS 2 semiconductor channel and graphene electrodes. Single-layer graphene was used as the source/drain and coplanar gate electrodes. An ion gel with an ultrahigh capacitance effectively gated the ReS 2 channel at a low voltage, below 2 V, through a coplanar gate. The contact resistance of the ion gel-gated ReS 2 transistors with graphene electrodes decreased dramatically compared with the SiO 2 -devices prepared with Cr electrodes. The resulting transistors exhibited good device performances, including a maximum electron mobility of 0.9 cm 2 /(V s) and an on/off current ratio exceeding 10 4 . NMOS logic devices, such as NOT, NAND, and NOR gates, were assembled using the resulting transistors as a proof of concept demonstration of the applicability of the devices to complex logic circuits. The large-area synthesis of ReS 2 semiconductors and graphene electrodes and their applications in logic devices open up new opportunities for realizing future flexible electronics based on 2D nanomaterials.

    Mitochondria are sub-cellular organelles that have a central role in energy production and in other metabolic pathways of all eukaryotic respiring cells. In the last few years, with more and more genomes being sequenced, a huge amount of data has been generated providing an unprecedented opportunity to use the comparative analysis approach in studies of evolution and functional genomics with the aim of shedding light on molecular mechanisms regulating mitochondrial biogenesis and metabolism. In this context, the problem of the optimal extraction of representative datasets of genomic and proteomic data assumes a crucial importance. Specialised resources for nuclear-encoded mitochondria-related proteins already exist; however, no mitochondrial database is currently available with the same features of MitoRes, which is an update of the MitoNuc database extensively modified in its structure, data sources and graphical interface. It contains data on nuclear-encoded mitochondria-related products for any metazoan species for which this type of data is available and also provides comprehensive sequence datasets (gene, transcript and protein) as well as useful tools for their extraction and export. MitoRes http://www2.ba.itb.cnr.it/MitoRes/ consolidates information from publicly external sources and automatically annotates them into a relational database. Additionally, it also clusters proteins on the basis of their sequence similarity and interconnects them with genomic data. The search engine and sequence management tools allow the query/retrieval of the database content and the extraction and export of sequences (gene, transcript, protein) and related sub-sequences (intron, exon, UTR, CDS, signal peptide and gene flanking regions) ready to be used for in silico analysis. The tool we describe here has been developed to support lab scientists and bioinformaticians alike in the characterization of molecular features and evolution of mitochondrial targeting sequences.

    Enhanced in 2014, the energy and climate goals for 2030 of the European Union require the mobilization of everyone, everywhere. In a dynamic set to intensify rural territories, as well as cities, the communities have a major role to play. As the principal trustees of renewable resource deposits, they are the vanguard of the energy transition. Their strengths? Wind and water in abundance (very often), the sun of course, biomass - agricultural, forest, woodland, domestic, food processing - geothermal energy. With the desire to make this renewable capital live, it made some decide to take or regain control of the energy issue, reduce their energy bills and those of their inhabitants. Attracted by the opportunity to revitalize local economies and rural communes (alone or in groups) they are more likely to want to become 100% RES. But how to move from intention to action when faced with the lack of knowledge, or means, or when you feel too small to act? It is to assist you in developing your energy policy that this guide was written. Pragmatic, practical, it brings together the return on experience from partners and communities involved in 100% RES Communities project. For three years, elected representatives from rural areas, some experienced and some less, together with experts from 10 countries in Europe, have sought the best organizational, technical and financial means to reduce consumption and produce renewable energy. If because of the administrative, cultural, economic differences within the Union, all the territories do not enjoy the same facilities, the 100% RES Communities project has defined pragmatic methods, practices and tools which will make your work easier. You will find in this guide the key steps in defining your strategy and building your action plan. This is a feasible action plan to be shared and implemented with the stakeholders. A final note: because it is within networks that we discover new solutions, which can replenish the practices and

    Denatured radioiodinated human serum albumin (DHA) clearance studies at a dose of 1 mg/kg body wt., were carried out in 16 thalassemic children, prior to and 7-10 days following blood transfusion, to investigate changes of the effective RES blood flow which might accompany the posttransfusion spleen size diminution. A statistically significant increase (P<0.001) of the DHA plasma clearance rate was observed 7-10 days following blood transfusion denoting an increase of the blood flow to the effective RES while at the same time the spleen diminished in size. It is suggested that changes in the effective RES blood flow in these patients are directly related to changes in the intrasplenic circulatory capacity. (orig.)

    Full Text Available Aiming to evaluate the effect of tomato waste inclusion on productive performance and characteristics of carcass and main broiler chicken cuts, an experiment was carried out using 300 male Cobb chicks, distributed in a complete randomized design, with five rations and five replicates. Diets consisted of control ration based on corn and soybean meal and four rations with 5, 10, 15 and 20% of tomato waste. Feed intake, weight gain and feed conversion and, at the end of experiment, slaughter weight, gutted carcass without feet and head, breast, drumstick, thigh, wing, back, edible guts and belly fat were evaluated every week, as well as it was the yield. Tomato waste increased feed intake in the periods from 1 to 7, 8 to 14 and 29 to 36 days of age and worsened gain weight and feed conversion of broiler chickens up to 29 days of age. Regarding carcass weight (g and weight of the noble parts, breast, drumstick and thighs decreased linearly in function of the use of tomato waste in poultry on pre- initial and initial phase, that is, up to 28 days old, but yield (% was not affected except for yield of heart and liver. Use of tomato waste in ration of broiler chickens during the period from 1 to 28 days may decrease weight gain and worsen food conversion. Tomato waste may be used as ration ingredient in ration of broiler chicken in the breeding period from 29 to 42 days of age up to the level of 20% without harming weight gain and feed conversion of poultry.Com o objetivo de avaliar o efeito da inclusão do resíduo do tomate sobre o desempenho produtivo e as características da carcaça e dos principais cortes de frangos de corte, foi realizado um experimento com 300 pintos machos Cobb, distribuídos em delineamento inteiramente casualizado, com cinco rações e cinco repetições.

  1. Who benefits from cooperation? A numerical analysis of redistribution effects resulting from cooperation in European RES-E support

    2014-01-01

    This paper numerically analyzes redistribution effects resulting from cooperation among European countries in achieving the 2020 targets for electricity generation from renewable energy sources (RES-E). The quanti cation of redistribution effects builds on the theoretical analysis by Unteutsch (2014), who shows that cooperation in RES-E support increases overall welfare but is not beneficial for all groups. In this paper, we use a dynamic investment and dispatch optimization model of the European electricity system to investigate which groups potentially benefit from cooperation and which groups would be worse off compared to a situation in which national RES-E targets are reached solely by domestic RES-E production. In the analysis, cooperation in RES-E support is implemented as a European-wide green certificate trading scheme. Main findings of the analysis include that in the European electricity system, effects of the change in the certificate price in most countries would overcompensate for the effects of the change in the wholesale electricity price. Thus, in most countries with comparatively high (low) generation costs for renewable energies, consumer rents increase (decrease) due to cooperation and producers yield lower (higher) profits. In addition, it is found that the magnitude of redistribution effects between the individual groups is quite large: In some countries, the change in consumer rents or producer profits resulting from cooperation is nearly twice as high as the overall welfare effect of cooperation in the whole European electricity system. Moreover, we find that the sign, but not always the magnitude, of redistribution effects is quite robust to different developments of interconnector extensions, the CO 2 price and RES-E investment costs.

  8. An RES-Based Model for Risk Assessment and Prediction of Backbreak in Bench Blasting

    Most blasting operations are associated with various forms of energy loss, emerging as environmental side effects of rock blasting, such as flyrock, vibration, airblast, and backbreak. Backbreak is an adverse phenomenon in rock blasting operations, which imposes risk and increases operation expenses because of safety reduction due to the instability of walls, poor fragmentation, and uneven burden in subsequent blasts. In this paper, based on the basic concepts of a rock engineering systems (RES) approach, a new model for the prediction of backbreak and the risk associated with a blast is presented. The newly suggested model involves 16 effective parameters on backbreak due to blasting, while retaining simplicity as well. The data for 30 blasts, carried out at Sungun copper mine, western Iran, were used to predict backbreak and the level of risk corresponding to each blast by the RES-based model. The results obtained were compared with the backbreak measured for each blast, which showed that the level of risk achieved is in consistence with the backbreak measured. The maximum level of risk [vulnerability index (VI) = 60] was associated with blast No. 2, for which the corresponding average backbreak was the highest achieved (9.25 m). Also, for blasts with levels of risk under 40, the minimum average backbreaks (<4 m) were observed. Furthermore, to evaluate the model performance for backbreak prediction, the coefficient of correlation ( R 2) and root mean square error (RMSE) of the model were calculated ( R 2 = 0.8; RMSE = 1.07), indicating the good performance of the model.

    The retention and splicing (RES) complex is a conserved spliceosome-associated module that was shown to enhance splicing of a subset of transcripts and promote the nuclear retention of unspliced pre-mRNAs in yeast. The heterotrimeric RES complex is organized around the Snu17p protein that binds to both the Bud13p and Pml1p subunits. Snu17p exhibits an RRM domain that resembles a U2AF homology motif (UHM) and Bud13p harbors a Trp residue reminiscent of an UHM-ligand motif (ULM). It has therefore been proposed that the interaction between Snu17p and Bud13p resembles canonical UHM-ULM complexes. Here, we have used biochemical and NMR structural analysis to characterize the structure of the yeast Snu17p-Bud13p complex. Unlike known UHMs that sequester the Trp residue of the ULM ligand in a hydrophobic pocket, Snu17p and Bud13p utilize a large interaction surface formed around the two helices of the Snu17p domain. In total 18 residues of the Bud13p ligand wrap around the Snu17p helical surface in an U-turn-like arrangement. The invariant Trp(232) in Bud13p is located in the center of the turn, and contacts surface residues of Snu17p. The structural data are supported by mutational analysis and indicate that Snu17p provides an extended binding surface with Bud13p that is notably distinct from canonical UHM-ULM interactions. Our data highlight structural diversity in RRM-protein interactions, analogous to the one seen for nucleic acid interactions. © 2014 by The American Society for Biochemistry and Molecular Biology, Inc.

  10. Integrated electrification solution for autonomous electrical networks on the basis of RES and energy storage configurations

    2008-01-01

    Most medium and small islands of the Aegean Archipelagos face serious infrastructure problems, strongly related with the limited electrical energy available at extremely high cost. On the other hand, the area is characterized by very high wind speeds and abundant solar energy, thus the exploitation of the available renewable energy sources (RES) may significantly contribute to the fulfillment of the local societies energy demand at minimum environmental and macroeconomic cost. However, the stochastic availability of wind energy and the variable availability of solar energy, the daily and seasonal electricity demand fluctuations, as well as the limited local electrical network capacity result in serious restrictions concerning the maximum renewable power penetration. In this context, the present paper investigates the possibility of creating a combined electricity generation facility based on the exploitation of wind or/and solar potential of an area as well as on the utilization of an appropriate energy storage configuration in order to replace the existing thermal power stations with rational investment requirements. For this purpose, the major parameters of the proposed integrated configuration are firstly calculated and its financial viability is accordingly analyzed. One of the main targets of the proposed solution is to maximize the RES exploitation of the area at a minimum electricity generation cost, while special emphasis is given in order to select the most cost-efficient energy storage device available. According to the results obtained the proposed solution is not only financially attractive but also improves the quality of the electricity offered to the local communities, substituting the expensive and heavily polluting existing thermal power stations

    Full Text Available Physico-chemical and mineralogical studies of the soils of the São Paulo State by the Soil Division of The Agronomical Institute proved the existence of different violet soils in South-Brasil and its origin from basaltic rocks. The Brasilian denomination "terra roxa" is already many times translated to "red soil", which is inexact, because the colour "roxa" corresponds to "violet" in English. We must insist on the perfection of Brasilian expression, which gives the shortest and the best characteristic of the true violet soil, derived through the decomposition of basalts and diabases in the São Paulo State. The term "red soil" originated much confusion, because there are in this state many "red soils" of different origins, but the true violet soil is quite unique. The violet colour of this soil appears very beautifully on the clean fields above the diabase hills at the distance of some hundreds of meters. In the state of complete dryness the violet soil becomes coffee brown, but never gets a red colour. The violet soil is the best soil of South America, on the contrary the red soils, which are mostly lateritic, are bad soils. Some exceptions, do exist, of course. The basalts produce laterites and other red soils of better qualities. With the purpose to contribute to the study of the violet and the red soils the present essay was made, describing the basic rocks of South-Brasil, as mother rocks of soils. The basic monograph of Djalma Guimarães "Magmatic Province of South-Brasil" (5, many times mentioned in the petrographic literature, definitively established the principal types and the mineral-components of triassic basic rocks in South-Brasil.

    Camille Ferreira Mannarino

    Full Text Available RESUMO: Esse trabalho tem como objetivo apresentar dados relevantes sobre o gerenciamento de resíduos sólidos urbanos (RSU na Europa de forma a se estabelecer paralelos e subsidiar a discussão no Brasil. É apresentada uma contextualização da situação atual da gestão dos resíduos sólidos urbanos no Brasil, onde os efeitos da Política Nacional de Resíduos Sólidos já se fazem sentir, sobretudo com o aumento da disposição final de RSU em aterros sanitários, predominantemente nas regiões metropolitanas. A reciclagem no país, em grande parte, ainda baseia-se na coleta informal por catadores ou na ação de organizações privadas. Na Europa, a partir da Diretiva 1999/31/EC, que estabeleceu metas para a disposição de resíduos em aterros sanitários, e da Diretiva 94/62/EC, sobre recolhimento de embalagens, a gestão de RSU se alterou profundamente. São apresentados dados das tecnologias predominantes de tratamento e disposição final de RSU e alguns mecanismos para implementação da mudança de cenário na Europa. O exemplo suíço é detalhado, mostrando como a cobrança de tarifas impulsiona as ações da população. É preciso reconhecer que o gerenciamento de resíduos sólidos urbanos RSU tem que ser planejado da coleta até o destino final, utilizando e integrando diferentes tecnologias de tratamento, de acordo com as características locais. É relevante para o Brasil a avaliação criteriosa das soluções disponíveis, do ponto de vista técnico e operacional, considerando fortemente a sua aplicabilidade local.

    Penetration of renewable energy is strongly slowed by its characteristic intermittency and fluctuating trend and by the inadequacy of electricity networks. These issues can be addressed through the development of new or improved storage technologies with higher performance, availability, durability, safety and lower costs. In the present work, micro-grids characterized by the presence of different subsections including renewable plants coupled with batteries storage solution are investigated through the development of a suitable code. Several design conditions and features, related to RES plant, storage system and users, were considered in order to realize a sensitivity analysis aimed to examine, on a yearly base and with one minute time step, interactions among the different micro-grid subsections and to identify the best solutions from both economic and energy point of views. - Highlights: • Storage systems coupling to RES plants is investigated for micro-grids. • Interactions between RES plants, storage batteries and users are analyzed. • Self-consumption increases with storage installation. • Investment pay-back analysis is performed varying plant configurations. • Pay-back reduction up to 30–40% for new RES/Storage integrated installations.

  7. Current experience with support schemes for RES-E in Europe. A regulatory point of view

    International Nuclear Information System (INIS)

    Lackner, Ursula

    2006-01-01

    The need to reduce the dependence of the European economy on imported primary energy and the impact of fossil fuels on the environment has encouraged countries to increase the share of renewable energy sources (RES) for electricity supply. EU Directive 2001/77/EC requires EU Member States to take appropriate steps to introduce new incentive mechanisms in order to reach the target of generating 21 % of the electricity in the EU from RES. At the same time EU Directive 2003/54/EC takes significant steps towards establishing a single market in electricity across the EU. Under this directive, European energy regulators have a number of responsibilities. These include the avoidance of discrimination and the promotion of effective competition along with an efficient functioning of the market. One of their main tasks is to ensure that European consumers pay a final electricity price that is as cost reflective as possible. The final price shall also reflect the social and the environmental costs. At the current stage it is not unlikely that the promotion of renewable energy sources will create significant barriers and distortions on the liberalized electricity market. Several issues arising from the implementation of renewable incentive schemes and policies can be identified and are analysed below; - Conflicting targets on EU-Level; - The variation in the level of incentives may be greater among Member States than is justified by the real level of technology costs, or other factors; - Unbalanced burden sharing for final consumers, due to different allocation mechanisms and designs of support schemes; -The regulation and charges for relevant items of the electricity chain, such as connection and balancing costs, vary significantly among Member States and may introduce competitive advantages. The contents of the paper is as follows: 1 Background; 2 Conflicting targets on EU-Level; 3 Different support levels; 4 Unbalanced burden sharing of final customers; 5 Allocation of

Estudos realizados na região sul do Brasil mostraram que os resíduos gerados pela indústria calçadista foram superiores a 200 toneladas/mês em 2001, sendo o maior volume oriundo de recortes de placas expandidas. Por isso, o objetivo deste trabalho foi o de caracterizar resíduos de EVA de chapas expandidas, visando à reciclagem mecânica desse material. Análises em MEV demonstraram que o resíduo de EVA apresenta uma morfologia microcelular que é destruída após o processo de moagem. O resíduo de EVA moído apresenta duas fases, uma reticulada (matriz e uma não-reticulada (dispersa. O resíduo de EVA apresentou teor de gel de aproximadamente 75% em massa, cerca de 20% em massa de acetato de vinila (VAc, fora processado a partir de EVA com aproximadamente 28% de VAc e possui teor de carga inorgânica de 20% em massa, segundo análises em TGA.

    2012-04-01

    FOR MEDICAL HUMANITARIAN ORGANIZATIONS, MAKING THEIR SOURCES OF LEGITIMACY EXPLICIT IS A USEFUL EXERCISE, IN RESPONSE TO: misperceptions, concerns over the 'humanitarian space', controversies about specific humanitarian actions, challenges about resources allocation and moral suffering among humanitarian workers. This is also a difficult exercise, where normative criteria such as international law or humanitarian principles are often misrepresented as primary sources of legitimacy. This essay first argues for a morally principled definition of humanitarian medicine, based on the selfless intention of individual humanitarian actors. Taking Médecins Sans Frontières (MSF) as a case in point, a common source of moral legitimacy for medical humanitarian organizations is their cosmopolitan appeal to distributive justice and collective responsibility. More informally, their legitimacy is grounded in the rightfulness of specific actions and choices. This implies a constant commitment to publicity and accountability. Legitimacy is also generated by tangible support from the public to individual organizations, by commitments to professional integrity, and by academic alliances to support evidence-based practice and operational research.

    Recently megalopolises have become centres of economy development worldwide. Gradual growth in energy consumption and thereafter - enormous power production and delivery to sustain metropolis’ needs entailed, rapid increase in emissions of hazardous substances in quantities, no longer tolerable for secure residence in majority of these cities. Ekaterinburg, is one of them. In order to abridge harmful pollution in Ekaterinburg and further centralize economic importance of the city, this paper proposes to implement the concept of urban sustainable development/ref. / by introducing alternative energy sources, which would progressively displace traditional fossil fuels. A number of actual cases, where the concept was successfully implemented, were studied and analysed to demonstrate how different shares of renewables can become effective substitutes to conventional energy sources in the cities strongly dependent on them: 1. Energy strategy of Pecs (Hungary); 2. International low carbon city (ILCC) project (Shenzhen, China); 3. Electric power system template of Tangshan city (China). Further, regional environmental and economic specifics of Ekaterinburg were studied to understand power consumption needs and energy generation possibilities, which led authors to conclude on the alternative energy sources feasibility, plot specific flow chart for RES implementation in Ekaterinburg’s power network and outline recommendations for future works.

L’objectif de cette étude était d’identifier un ou plusieurs constituants lipidiques spécifiques des tissus nerveux, et principalement de la moelle épinière, permettant de vérifier l’absence de tissus nerveux dans les matières premières utilisées pour la fabrication de gélatine. Pour cela, la composition lipidique de la moelle épinière a été comparée à celle des matières premières de gélatine. La pertinence d’un paramètre (p, vis-à-vis d’une source donnée, a été évaluée par la valeur du facteur : F (p = [p]moelle épinière/[p] OS, qui est le rapport entre sa concentration dans les lipides de moelle épinière et celle dans la source osseuse considérée. Plus la valeur de F est élevée, plus le paramètre est pertinent.

This study assessed the N contribution of peanut (Arachis hypogaea L. residues to a subsequent rye (Secale cereale L. cover crop grown in a conservation system on a Dothan sandy loam (fine-loamy, kaolinitic, thermic Plinthic Kandiudults at Headland, AL USA during the 2003-2005 growing seasons. Treatments were arranged in a split plot design, with main plots of peanut residue retained or removed from the soil surface, and subplots as N application rates (0, 34, 67 and 101 kg ha-1 applied in the fall. Peanut residue had minimal to no effect on rye biomass yields, N content, carbon (C /N ratio, or N, P, K, Ca and Zn uptake. Additional N increased rye biomass yield, and N, P, K, Ca, and Zn uptakes. Peanut residue does not contribute significant amounts of N to a rye cover crop grown as part of a conservation system, but retaining peanut residue on the soil surface could protect the soil from erosion early in the fall and winter before a rye cover crop grows sufficiently to protect the typically degraded southeastern USA soils.Culturas leguminosas de inverno tem sido utilizadas em sistemas conservacionistas para suprimento parcial das necessidades de nitrogênio (N de culturas subseqüentes de verão, mas o potencial destas culturas leguminosas de verão no sentido de reduzir as necessidades de N de gramíneas anuais de inverno, utilizadas como culturas de cobertura, ainda não foi extensivamente estudado.

A total of 526 stained-glass works was surveyed and studied; 286 are designs with figures, 37 of these classifiable as stained-glass picture compositions. The remaining 240 works are ornamental. Behind this production, we find some 22 different stained-glass producers, amongst the most important of which are Didron, Lusson, Champigneulle, Hirsch and Gsell. Paris played a leading role in the revival of stained glass during the early years of the 19th century, thanks in part to the perspicacious inspiration of certain figures in power, such as the Prefect of Paris, the Comte de Chabrol, who was at the origins of the ‘resurrection’ of the skill of stained-glass painters with the 1825 creation of the works at the Foire Saint-Laurent. Further inspiration came from the first restoration work carried out on older stained-glass works, and the decisive role of diocesan architects. The iconography of these works reflects the evolution of France’s religious life during the period, from the liberty of the Concordat to

    Layered rhenium disulfide (ReS 2 ) field effect transistors (FETs), with thickness ranging from few to dozens of layers, are demonstrated on 20 nm thick HfO 2 /Si substrates. A small threshold voltage of -0.25 V, high on/off current ratio of up to ∼10 7 , small subthreshold swing of 116 mV/dec, and electron carrier mobility of 6.02 cm 2 /V·s are obtained for the two-layer ReS 2 FETs. Low-frequency noise characteristics in ReS 2 FETs are analyzed for the first time, and it is found that the carrier number fluctuation mechanism well describes the flicker (1/f) noise of ReS 2 FETs with different thicknesses. pH sensing using a two-layer ReS 2 FET with HfO 2 as a sensing oxide is then demonstrated with a voltage sensitivity of 54.8 mV/pH and a current sensitivity of 126. The noise characteristics of the ReS 2 FET-based pH sensors are also examined, and a corresponding detection limit of 0.0132 pH is obtained. Our studies suggest the high potential of ReS 2 for future low-power nanoelectronics and biosensor applications.

    Full Text Available Resumo O estudo teve por objetivo analisar de que forma tecnologias de informação e comunicação (TIC, e a internet em particular, são empregadas para apoiar a gestão de resíduos sólidos urbanos (RSU no nível municipal. Para tanto, analisaram-se os websites dos 34 municípios da Bacia Hidrográfica do Alto Tietê em relação às informações de programas de coleta seletiva, uso de Pontos de Entrega Voluntária (PEVs e o acesso ao Plano de Gestão Integrada de Resíduos Sólidos (PGIRS. Os resultados revelam que a maior parte dos municípios utilizam as TIC de forma limitada, e as subutilizam na divulgação de informações relevantes à população, sobretudo no que diz respeito às formas adequadas de separação e acondicionamento dos resíduos sólidos para a coleta seletiva. Isso pode reduzir o desempenho desse serviço público e aumentar os riscos à saúde dos catadores que atuam na reciclagem desses materiais. Concluiu-se que um melhor uso de TIC para o adequado monitoramento e difusão de informações sobre resíduos sólidos urbanos pode ser um mecanismo efetivo para o cumprimento dos objetivos e metas determinados pela Política Nacional de Resíduos Sólidos no nível local e para práticas de accountability e informação aos cidadãos.

    Full Text Available Uma das áreas em ascensão no Brasil é a construção civil, o qual é um setor que gera impactos ambientais, dentre eles, um número elevado de resíduos sólidos. Em razão disso, este estudo tem como objetivos identificar e avaliar o que as empresas do ramo da construção civil listadas na BM&FBOVESPA evidenciam em seus relatórios de sustentabilidade relativamente à gestão de seus resíduos. Para atender aos objetivos propostos, foram pesquisados os relatórios de sustentabilidade das empresas listadas na BM&FBOVESPA do setor de construção civil. Os resultados mostraram que pequena parte do total de empresas listadas divulga o relatório de sustentabilidade e que, das duas empresas identificadas, após a análise das informações efetivamente divulgadas, uma apresentou dados referentes a 96% dos itens da Categoria Ambiental da Global Reporting Initiative (GRI, e a outra apresentou apenas 19% dos itens. Além disso, em ambas as empresas foram identificados itens em que a divulgação foi feita de forma parcial ou sequer foi feita. O estudo conclui que mesmo a construção civil sendo uma área em expansão e geradora de resíduos, são poucas as empresas que apresentam relatório socioambiental.

    Full Text Available Os resíduos agroindustriais geralmente apresentam grandes concentrações de materiais orgânicos que, se manejados de forma inadequada, podem poluir e/ou contaminar o solo, a água e o ar. A técnica de compostagem tem se mostrado um processo eficiente na busca pela minimização da problemática ambiental associada aos resíduos orgânicos e na redução do volume de resíduos descartados em lixões e aterros sanitários. O principal objetivo deste trabalho consiste na utilização de parâmetros físico-químicos para verificar a maturação de compostos orgânicos obtidos a partir de resíduos agroindustriais da região de Pombal, um município localizado no semiárido paraibano. Para obtenção dos compostos orgânicos, cascas de bananas, estercos ovinos e podas de marmeleiro e jurema-preta foram triturados e misturados para montar duas pilhas de compostagem, sendo uma depositada em solo compactado e outra sobre um pátio pavimentado com concreto. Os parâmetros utilizados na avaliação da maturação foram: temperatura, relação C/N, condutividade elétrica, pH e demanda química de oxigênio. Os resultados sugerem que os compostos orgânicos estudados estão maturados, indicando que estes simples métodos são considerados seguros para verificação de processos de compostagem conduzidos em regiões sujeitas às condições semiáridas. 

  9. Immunoreactive serum opsonic alpha 2 sb glycoprotein as a noninvasive index of RES systemic defense after trauma.

    Reticuloendothelial system (RES) depression has been correlated with diminished resistance to trauma, shock, and sepsis in man and animals. Previous studies have related the depression of RES hepatic Kupffer cell phagocytic function after trauma to diminished bioassayable opsonic activity. The present study determined if the loss of biological activity and RES alteration correlated with immunoreactive serum opsonic alpha 2 SB glycoprotein levels after trauma. Serum opsonic activity was measured by liver slice bioassay, and immunoreactive opsonic protein was measured by rocket electroimmunoassay. RE function was determined by colloid clearance over a 24-hour post-trauma period. Anesthetized rats (250-300 gm) subjected to sublethal or severe (greater than LD50) whole-body NCD trauma were the shock models investigated. Immunoreactive levels in 63 rats prior to injury were 518 +/- 24 microgram/ml. Neither biological nor immunoreactive levels were altered over 24 hours in anesthetized sham-traumatized controls. Temporal alteration in the initial decrease and recovery pattern of biologically active and immunoreactive opsonic protein levels significantly correlated following both sublethal and severe injury. Moreover, the patterns of immunoreactive levels of the opsonic protein correlated with the functional phagocytic activity of the RES as determined by vascular clearance of a test dose of blood-borne radiolabeled particulates. This glycoprotein falls after trauma, and the magnitude and duration of the decline increases with severity of injury. Immunoreactive opsonic alpha 2 SB glycoprotein appears to be an accurate measurement of circulating opsonic activity and RE Kupffer cell function after trauma, especially with respect to clearance. Thus, immunoreactive opsonic protein warrants clinical consideration as a noninvasive measure of reticuloendothelial systemic defense in patients after trauma and burn.

    Aicardi-Goutières syndrome (AGS) is a genetic encephalopathy whose clinical features mimic those of acquired in utero viral infection. AGS exhibits locus heterogeneity, with mutations identified in genes encoding the 3′→5′ exonuclease TREX1 and the three subunits of the RNASEH2 endonuclease complex. To define the molecular spectrum of AGS, we performed mutation screening in patients, from 127 pedigrees, with a clinical diagnosis of the disease. Biallelic mutations in TREX1, RNASEH2A, RNASEH2B, and RNASEH2C were observed in 31, 3, 47, and 18 families, respectively. In five families, we identified an RNASEH2A or RNASEH2B mutation on one allele only. In one child, the disease occurred because of a de novo heterozygous TREX1 mutation. In 22 families, no mutations were found. Null mutations were common in TREX1, although a specific missense mutation was observed frequently in patients from northern Europe. Almost all mutations in RNASEH2A, RNASEH2B, and RNASEH2C were missense. We identified an RNASEH2C founder mutation in 13 Pakistani families. We also collected clinical data from 123 mutation-positive patients. Two clinical presentations could be delineated: an early-onset neonatal form, highly reminiscent of congenital infection seen particularly with TREX1 mutations, and a later-onset presentation, sometimes occurring after several months of normal development and occasionally associated with remarkably preserved neurological function, most frequently due to RNASEH2B mutations. Mortality was correlated with genotype; 34.3% of patients with TREX1, RNASEH2A, and RNASEH2C mutations versus 8.0% RNASEH2B mutation–positive patients were known to have died (P=.001). Our analysis defines the phenotypic spectrum of AGS and suggests a coherent mutation-screening strategy in this heterogeneous disorder. Additionally, our data indicate that at least one further AGS-causing gene remains to be identified. PMID:17846997

    Full Text Available La recherche sur laquelle repose cet article analyse la place des coutumes des marges de l’apprentissage universitaire dans la construction du personnage du médecin spécialiste français, dans lequel l’internat et les manières à y apprendre sont centrales. Environ cent entretiens ethnographiques avec des spécialistes d’âges et d’exercices variés ont été menés. L’internat concerne les futurs spécialistes, reçus au concours de l’internat qui donne accès, après 6 années d’étude communes à tous les médecins, à une formation propre de 4-6 années supplémentaires, pendant laquelle ils apprennent non seulement leur profession auprès de malades et de patrons, mais aussi les manières constitutives du personnage du spécialiste, en fréquentant internes et internats. Chaque midi à table, les internes acquièrent ces manières de salle de garde. À travers l’apprentissage de règles contraignantes et souvent paradoxales, de savoir-dire et de savoir-faire, autrement dit de savoir-être propres au groupe, ils vont acquérir une compétence spécifique : nouveau calendrier, nouvelle langue, nouveau code comportemental, nouvelle hiérarchie, nouveaux devoirs… dont le non-respect est sanctionné par des gages codifiés. La mise en place de rituels collectifs fondant la communauté, l’application de codes précis, la valorisation de modèles identificatoires permettent à chacun de prendre place, de s’impliquer selon une organisation concentrique, de donner sens aux expériences en cours en les intégrant dans une logique initiatique.

    ReS2, a layered two-dimensional material popular for its in-plane anisotropic properties, is emerging as one of the potential candidates for flexible electronics and ultrafast optical applications. It is an n-type semiconducting material having a layer independent bandgap of 1.55 eV. In this paper we have characterized the intrinsic electronic noise level of few-layer ReS2 for the first time. Few-layer ReS2 field effect transistor devices show a 1/f nature of noise for frequency ranging over three orders of magnitude. We have also observed that not only the electrical response of the material is anisotropic; the noise level is also dependent on direction. In fact the noise is found to be more sensitive towards the anisotropy. This fact has been explained by evoking the theory where the Hooge parameter is not a constant quantity, but has a distinct power law dependence on mobility along the two-axes direction. The anisotropy in 1/f noise measurement will pave the way to quantify the anisotropic nature of two-dimensional (2D) materials, which will be helpful for the design of low-noise transistors in future.

  16. Applying Rock Engineering Systems (RES approach to Evaluate and Classify the Coal Spontaneous Combustion Potential in Eastern Alborz Coal Mines

    2013-12-01

    Full Text Available Subject analysis of the potential of spontaneous combustion in coal layers with analytical and numerical methods has been always considered as a difficult task because of the complexity of the coal behavior and the number of factors influencing it. Empirical methods, due to accounting for certain and specific factors, have not accuracy and efficiency for all positions. The Rock Engineering Systems (RES approach as a systematic method for analyzing and classifying is proposed in engineering projects. The present study is concerned with employing the RES approach to categorize coal spontaneous combustion in coal regions. Using this approach, the interaction of parameters affecting each other in an equal scale on the coal spontaneous combustion was evaluated. The Intrinsic, geological and mining characteristics of coal seams were studied in order to identifying important parameters. Then, the main stages of implementation of the RES method i.e. interaction matrix formation, coding matrix and forming a list category were performed. Later, an index of Coal Spontaneous Combustion Potential (CSCPi was determined to format the mathematical equation. Then, the obtained data related to the intrinsic, geological and mining, and special index were calculated for each layer in the case study (Pashkalat coal region, Iran. So, the study offers a perfect and comprehensive classification of the layers. Finally, by using the event of spontaneous combustion occurred in Pashkalat coal region, an initial validation for this systematic approach in the study area was conducted, which suggested relatively good concordance in Pashkalat coal region.

    ReS 2 films are considered as a promising candidate for optoelectronic applications due to their direct band gap character and optical/electrical anisotropy. However, the direct band gap in a narrow spectrum and the low absorption of atomically thin flakes weaken the prospect for light-harvesting applications. Here, we developed an efficient approach to enhance the performance of a ReS 2 -based phototransistor by coupling CdSe-CdS-ZnS core-shell quantum dots. Under 589 nm laser irradiation, the responsivity of the ReS 2 phototransistor decorated with quantum dots could be enhanced by more than 25 times (up to ∼654 A/W) and the rising and recovery time can be also reduced to 3.2 and 2.8 s, respectively. The excellent optoelectronic performance is originated from the coupling effect of quantum dots light absorber and cross-linker ligands 1,2-ethanedithiol. Photoexcited electron-hole pairs in quantum dots can separate and transfer efficiently due to the type-II band alignment and charge exchange process at the interface. Our work shows that the simple hybrid zero- and two-dimensional hybrid system can be employed for photodetection applications.

Cet article propose d’étudier les villes frontalières thaïlandaises, et plus précisément celles situées sur les corridors de développement mis en place dans le cadre de la coopération régionale. Si ces villes sont longtemps apparues comme des espaces périphériques, peu intégrés au territoire national, deux dynamiques contemporaines modifient cet état de fait : le mouvement de déconcentration initié par le gouvernement thaïlandais dès le milieu des années 1970 d’une part, et surtout la coopération régionale marquant le tournant des années 1990 d’autre part. Les villes frontalières thaïlandaises sont devenues depuis une vingtaine d’années des objets spécifiques de la planification gouvernementale. D’espaces périphériques, elles ont été promues gateways, pôles de croissance économiques et soutien au commerce avec les pays limitrophes. Même si leur place dans le tissu urbain national diverge encore largement, des projets d’infrastructures leur permet d’acquérir une nouvelle envergure. L’étude de cas de trois villes sélectionnées montrent que si elles diffèrent au regard de critères démographiques, économiques ou en termes d’équipements, ces villes ont toutes connu au cours des dernières années et sous l’effet combiné de la régionalisation et de la planification une modification de leur organisation spatiale. De nouveaux centres apparaissent, et la diversité des acteurs impliqués ainsi que les dynamiques en cours sont à même de modifier de manière variable les relations entretenues avec les centres urbains situés de l’autre côté de la frontière d’une part, et la place de ces villes frontalières thaïlandaises dans le tissu urbain national et régional d’autre part.This paper will focus on Thai bordertowns located on ADB economic corridors.

    Full Text Available A Ilha do Mel, reconhecido destino turístico do litoral do Estado do Paraná, Brasil, que enlaça duas áreas de preservação ambiental, passou por consideráveis alterações socioambientais e econômicas a partir da década de 1980, em função do aumento da demanda turística. O desenvolvimento do turismo possibilitou o surgimento de mais de cem hotéis e pousadas em seu território, concentração essa que se tornou um grave problema para a gestão pública dos resíduos sólidos. Neste contexto, o objetivo desta pesquisa é o de analisar a gestão dos resíduos sólidos realizada pelos meios de hospedagem e pelo setor público, bem como verificar a opinião dos empreendedores privados sobre o tratamento dado a esses resíduos, no local. Os dados primários foram coletados através de entrevistas realizadas com empresários de trinta meios de hospedagem e com representantes do setor público local. Os resultados indicam que muitas das ações de tratamento e destinação dos resíduos sólidos acontecem, em geral, pelo livre arbítrio dos proprietários. Por parte do setor público, foi verificada ausência de estruturas físicas adequadas para a gestão dos resíduos sólidos, assim como de critérios claros para o tratamento e destinação destes resíduos e a falta de orientações efetivas aos empresários.

Il s’agit de mettre en avant l’exploit de ces citadins, qui sortent des villes, et sont confrontés à la nature et au monde rural. La confrontation entre un monde idéalisé et un territoire transparaît dans les récits. Les aménagements des rivières constituent la partie visible du rapport du citadin à la nature.

Mais cet espace ne doit pas prendre les traits de la ville qu’il vient de quitter.Travel stories constitute a literature that reveals the development of nautical tourism. The rediscovery of French rivers, carried out by well-off city dwellers, is based on myths about the return to nature and the personification of the elements. It’s a matter of highlighting the feat of these townsmen, who leave the cities and face nature and rural life. The confrontation between an idealized world and a territory shows through the stories. The development of the rivers constitutes the visible part of the relationship between the city dwellers and nature. The space to explore must allow the city dwellers to go in for an activity closely related to nature. But this space should not take the features of the city he has just left.

    Efficient biofilm formation and root colonization capabilities facilitate the ability of beneficial plant rhizobacteria to promote plant growth and antagonize soilborne pathogens. Biofilm formation by plant-beneficial Bacillus strains is triggered by environmental cues, including oxygen deficiency, but the pathways that sense these environmental signals and regulate biofilm formation have not been thoroughly elucidated. In this study, we showed that the ResDE two-component regulatory system in the plant growth-promoting rhizobacterium Bacillus amyloliquefaciens strain SQR9 senses the oxygen deficiency signal and regulates biofilm formation. ResE is activated by sensing the oxygen limitation-induced reduction of the NAD + /NADH pool through its PAS domain, stimulating its kinase activity, and resulting in the transfer of a phosphoryl group to ResD. The phosphorylated ResD directly binds to the promoter regions of the qoxABCD and ctaCDEF operons to improve the biosynthesis of terminal oxidases, which can interact with KinB to activate biofilm formation. These results not only revealed the novel regulatory function of the ResDE two-component system but also contributed to the understanding of the complicated regulatory network governing Bacillus biofilm formation. This research may help to enhance the root colonization and the plant-beneficial efficiency of SQR9 and other Bacillus rhizobacteria used in agriculture. IMPORTANCE Bacillus spp. are widely used as bioinoculants for plant growth promotion and disease suppression. The exertion of their plant-beneficial functions is largely dependent on their root colonization, which is closely related to their biofilm formation capabilities. On the other hand, Bacillus is the model bacterium for biofilm study, and the process and molecular network of biofilm formation are well characterized (B. Mielich-Süss and D.

  13. The impact of rhetoric and education on the "Res Gestae" of Ammianus Marcellinus

    Science.gov (United States)

    Alvarez, Pablo

    The aim of this thesis is to explore and underline the impact of education and rhetoric on the Res Gestae of Ammianus Marcellinus. I will examine the concept of education in two different aspects. First, I will determine the role of education in regards to Ammianus' early life by describing the cultural climate in the East in the fourth century (Introduction and chapter 1). In this analysis, I will argue that the historian's familiarity with Latin suggests an early acquaintance with the language, indicating that he should not be invariably associated with earlier Greek historians. Second, I will look at how the content of the curriculum is reflected in the RG, explaining how literary sources shaped the composition of the historian's digressions on geography (Chapter 3) and astronomy (Chapter 4). In the past, scholars have examined Ammianus' cultural digressions as an example of the tension between things seen and things read. In my argumentation, I will concentrate on explaining the reasons why Ammianus often tended to rely on literary works rather than observation. I will show that the explanation greatly lies in the content of the curriculum. Concerning the role of rhetoric, I will examine how rhetorical training is articulated in the RG. In Chapter 2, I will show that Ammianus' selection of historical material can be explained in light of the ancient theory of styles. In this context, I will study the role of a rhetorical device designed to raise the emotions of readers by bringing the scene before their eyes: enargeia. In Chapters 3 and 4, I will demonstrate that the cultural digressions in the RG are mostly the product of cultural stereotypes and literary influences. In Chapter 5, I will show the impact of rhetorical treatises on some passages of the RG, arguing that the traditional classification of oratory into deliberative, epideictic and judicial is echoed in both the speeches and the historical narrative. To conclude: the main purpose of my dissertation

    Rock Engineering Systems (RES) is an approach to discover the important characteristics and interactions of a complex problem. Recently RES has been applied to identify features, events and processes (FEPs) for performance analysis of nuclear waste repositories. The RES methodology was applied to identify FEPs for the near-field analysis of the copper-steel canister for spent fuel disposal. The aims of the exercise were to learn and test the RES methodology and, secondly, to find out how much the results differ when RES is applied by two different groups on the same problem. A similar exercise was previously carried out by a SKB group. A total of 90 potentially significant FEPs were identified. The exercise showed that the RES methodology is a practicable tool to get a comprehensive and transparent picture of a complex problem. The approach is easy to learn and use. It reveals the important characteristics and interactions and organizes them in a format easy to understand. (9 refs., 5 figs., 3 tabs.)

    Full Text Available Resumo A substituição parcial de cimento Portland por resíduo de bauxita (RB resulta em produtos com, no mínimo, propriedades similares às dos produtos fabricados com o ligante puro. No entanto, as interações físico-químicas entre os diferentes tipos de cimento e o RB durante a reação de hidratação ainda é pouco explorada em literatura. A elevada quantidade de sódio e a presença de Al2O3, SiO2 e Fe2O3 são fatores que afetam a formação dos produtos hidratados e dependem do tipo de cimento utilizado na mistura. Sendo assim, este trabalho foi realizado com o objetivo de avaliar o impacto da presença do resíduo de bauxita em associação ao cimento Portland simples nas primeiras idades de hidratação. Calorimetria de condução isotérmica, difração de raios X, análise termogravimétrica e espectroscopia de infravermelho foram as técnicas escolhidas para o monitoramento. Os resultados ilustraram que a presença do resíduo coletado na planta da Alcoa (Poços de Caldas aumenta o tempo de indução, o consumo de portlandita, e as quantidades de etringita e monossulfoaluminato formadas. Ao mesmo tempo, houve formação de silicoaluminato de sódio e bicarbonato de sódio, devido às reações com silicatos, aluminatos e com o carbonato do cimento.

    The aim of the present study was to assess the precision of the OMNI-RES scale to predict energy cost (EC) at low intensity in four resistance exercises (RE). 17 male recreational body builders (age = 26.6 ± 4.9 years; height = 177.7 ± 0.1 cm; body weight = 79.0 ± 11.1 kg and percent body fat = 10.5 ± 4.6%) served as subjects. Initially tests to determine 1RM for four resistance exercises (bench press, half squat, lat pull down and triceps extension) were administered. Subjects also performed resistance exercise at 12, 16, 20, and 24% of 1RM at a rate of 40 bpm until volitional exhaustion. Oxygen uptake (VO2) and rate of perceived exertion (RPE) using the OMNI-RES were obtained during and after all RE. EC was calculated using VO2 and the caloric values of VO2 for non-protein RER. Regression analyses were performed for every RE, using EC as the dependent and RPE as the predictor variable. The triceps extension, lat pull down and bench press, RPE correlated strongly with EC (R > 0.97) and predicted EC with a error of less than 0.2 kcal.min−1. In conclusion, RPE using the OMNI-RES scale can be considered as an accurate indicator of EC in the bench press, lat pull down and triceps extension performed by recreational bodybuilders, provided lower intensities are used (up to 24% of 1-RM) and provided each set of exercise is performed for the maximal sustainable duration. It would be interesting in future studies to consider having the subjects exercise at low intensities for longer durations than those in the present study. PMID:23486188

    Fertile soils are central resources for the production of biomass and provision of food and energy. A growing world population and latest climate targets lead to an increasing demand for both, food and bio-energy, which require preserving and improving the long-term productivity of soils as a bio-economic resource. At the same time, other soil functions and ecosystem services need to be maintained. To render soil management sustainable, we need to establish a scientific knowledge base about complex soil system processes that allows for the development of model tools to quantitatively predict the impact of a multitude of management measures on soil functions. This, finally, will allow for the provision of site-specific options for sustainable soil management. To face this challenge, the German Federal Ministry of Education and Research recently launched the funding program "Soil as a Natural Resource for the Bio-Economy - BonaRes". In a joint effort, ten collaborative projects and the coordinating BonaRes Centre are engaged to close existing knowledge gaps for a profound and systemic understanding of soil functions and their sensitivity to soil management. This presentation provides an overview of the concept of the BonaRes Centre which is responsible for i) setting up a comprehensive data base for soil-related information, ii) the development of model tools aiming to estimate the impact of different management measures on soil functions, and iii) establishing a web-based portal providing decision support tools for a sustainable soil management. A specific focus of the presentation will be laid on the so-called "knowledge-portal" providing the infrastructure for a community effort towards a comprehensive meta-analysis on soil functions as a basis for future model developments.

    Full Text Available Uma das características do sistema de plantio direto é o acúmulo de resíduos culturais na superfície do solo. Embora as recomendações técnicas preconizem a remoção desses resíduos antes da amostragem de solo, isso não ocorre quando a amostragem é efetuada utilizando o quadriciclo. Os resíduos culturais também podem ser misturados com a amostra de solo quando esse é amostrado com o trado manual e esses resíduos não são removidos da superfície do solo. Neste trabalho, estudou-se a influência dos resíduos culturais da superfície do solo nos resultados da análise de solo sob plantio direto. Amostraram-se solos com e sem a remoção de resíduos culturais da superfície. Esses procedimentos foram testados em solos contendo baixo e alto teor de argila, amostrados com o trado calador e o quadriciclo, após o cultivo de soja e milho. A influência dos resíduos culturais no resultado da análise de solo foi, em geral, pouco expressiva, variando com o tipo de amostrador, de resíduo e teor de argila do solo. Nas amostras coletadas com o quadriciclo, foi possível detectar diferenças no teor de matéria orgânica (MO em função dos procedimentos de amostragem testados, entretanto, isso não ocorreu nas amostras coletadas com o calador. Na presença dos resíduos culturais, o teor de MO aumentou em 4g kg-1 (solo com baixo teor de argila e cultivado com soja e em 5g kg-1 (solo com alto teor de argila e cultivado com milho. Com exceção dos teores de MO, a presença dos resíduos culturais não interferiu na interpretação dos outros atributos analisados.

    Full Text Available FUNDAMENTO: A aterosclerose é uma doença inflamatória crônica de origem multifatorial que ocorre em resposta à agressão endotelial. O fungo Monascus ruber apresenta atividade hipocolesterolêmica e polifenóis presentes no resíduo de café apresentam atividade antioxidante, podendo auxiliar na prevenção de doenças cardiovasculares. O resíduo de café possui quantidade significativa de açúcares fermentescíveis, constituindo-se em substrato apropriado para o cultivo de fungos. OBJETIVO: O objetivo deste estudo foi avaliar o efeito dos resíduos de café seco e fermentado por Monascus ruber no metabolismo lipídico de camundongos knockout Apo E. MÉTODOS: O ensaio biológico foi realizado com 30 camundongos knockout para o gene Apo E, divididos em cinco grupos e submetidos a diferentes tratamentos. Foi realizada a prospecção fitoquímica e quantificação de compostos fenólicos dos resíduos fermentado e sem fermentar. O soro dos animais foi analisado utilizando kits enzimáticos e o tecido aórtico incluso em parafina e corado com H/E para realização da análise histopatológica. RESULTADOS: O resíduo de café sem fermentar 2%, em relação ao grupo controle, diminuiu em 42% o nível sérico de triacilgliceróis e em aproximadamente 41% a fração VLDL-c. Os grupos dos animais alimentados com 10% de resíduo não fermentado e 2% de resíduo fermentado diminuíram a área de lesão 10,5% e 15,4%, respectivamente, quando comparados ao controle. O resíduo fermentado apresentou um teor de compostos fenólicos superior ao resíduo não fermentado. CONCLUSÃO: O presente estudo mostra que a fermentação do resíduo de café apresenta potencial efeito benéfico sobre as doenças cardiovasculares, especialmente a aterosclerose.

    Aicardi-Goutières syndrome is a mendelian mimic of congenital infection and also shows overlap with systemic lupus erythematosus at both a clinical and biochemical level. The recent identification of mutations in TREX1 and genes encoding the RNASEH2 complex and studies of the function of TREX1 in DNA metabolism have defined a previously unknown mechanism for the initiation of autoimmunity by interferon-stimulatory nucleic acid. Here we describe mutations in SAMHD1 as the cause of AGS at the AGS5 locus and present data to show that SAMHD1 may act as a negative regulator of the cell-intrinsic antiviral response.

    Full Text Available RESUMO Com o crescimento da população e o consequente aumento da urbanização, o lançamento de resíduos sólidos nos sistemas de drenagem urbana tem aumentado nos últimos anos, principalmente nas regiões periféricas das cidades. Este estudo teve como objetivo qualificar e quantificar os resíduos sólidos no arroio Cancela-Tamandai, localizado em área urbana, no município de Santa Maria (RS. Foram coletados ao todo 1.153,2 kg de resíduos sólidos com uma precipitação pluviométrica total para o período de novembro de 2012 a janeiro de 2013 de 518,94 mm, sendo, desses, 93,9% composto por matéria orgânica, sendo a maioria vegetação. O arroio Cancela-Tamandai apresentou uma carga de resíduos sólidos igual a 17,27 ou 0,424 kg.hab-1.ano-1. A curva de previsão de resíduos sólidos orgânicos drenados em função da precipitação pluviométrica apresentou correlação de 76,4%, um parâmetro importante para a tomada de decisão dos gestores municipais em relação aos resíduos sólidos gerados. Assim, conceber estratégias para o monitoramento desses resíduos representa passo importante na busca de soluções que visem um melhor gerenciamento de bacias hidrográficas urbanas.

Esses resíduos foram colhidos em três estádios do desenvolvimento reprodutivo do sorgo: florescimento, enchimento de grãos e maturação. Os tratamentos estudados constaram da deposição desses resíduos na superfície do solo ou da sua total incorporação na proporção de 4 g kg-1 de matéria seca no solo (LEd, fase cerrado. Nos tratamentos com planta, mantiveram-se três plantas de soja (cv. Doko em vasos com capacidade para 3 kg de solo. Nos tratamentos sem planta, o solo foi amostrado semanalmente para avaliação das formas de N. Após a colheita da soja, amostras de planta e de solo, de cada tratamento, foram retiradas para determinar a absorção total de N e a influência desses resíduos no N disponível extraído com KCl 2 mol L-1. Os resultados revelaram que alguns resíduos culturais de sorgo afetaram, independentemente do estádio de colheita, o desenvolvimento da soja, a absorção de N, o peso de nódulos e a biomassa microbiana do solo. Tais efeitos também foram dependentes do método de incorporação do resíduo. O teor de carbono imobilizado pela biomassa foi maior quando os resíduos de sorgo foram distribuídos na superfície do solo.

    EU energy strategy is strongly focused on the large scale integration of renewable energy sources. The most dominant part here is taken by variable sources - wind power plants. Grid integration of intermittent sources along with keeping the system stable and secure is one of the biggest challenges for the TSOs. This part is often neglected by the energy policy makers, so this paper deals with expected future conditions for secure power system operation with large scale wind integration. It gives an overview of expected wind integration development in EU, as well as expected P/f regulation and control needs. The paper is concluded with several recommendations. (author).

    Full Text Available Descreve-se o aproveitamento do resíduo do desfibramento das folhas de Agave sisalana, como um larvicida para o combate a mosquitos transmissores de doenças tropicais. Durante 24 horas, larvas de Aedes aegypti e Culex quinquefasciatus foram expostas a concentrações diferentes do extrato da planta para determinar as concentrações letais. Para A. aegypti foi constatada a CL50 em 322ppm e para C. quinquefasciatus em 183ppm. Foi investigada a ação de saponinas existentes na planta, ficando evidenciado que o resíduo de A. sisalana é ativo através da interação de vários dos seus componentes. Este extrato poderá ser utilizado em campo, na concentração de 100ppm para C. quinquefasciatus com um aumento do tempo de exposição para três dias, obtendo-se uma mortalidade de 100% das larvas. Este produto, porém, não é recomendado para o controle de A. aegypti, devido à necessidade de uma alta concentração para a obtenção de 100% de mortalidade das larvas e ao fato destas se desenvolverem preferencialmente em água potável.

    2013-09-01

    Full Text Available Long interspersed elements 1 (LINE-1 occupy at least 17% of the human genome and are its only active autonomous retrotransposons. However, the host factors that regulate LINE-1 retrotransposition are not fully understood. Here, we demonstrate that the Aicardi-Goutières syndrome gene product SAMHD1, recently revealed to be an inhibitor of HIV/simian immunodeficiency virus (SIV infectivity and neutralized by the viral Vpx protein, is also a potent regulator of LINE-1 and LINE-1-mediated Alu/SVA retrotransposition. We also found that mutant SAMHD1s of Aicardi-Goutières syndrome patients are defective in LINE-1 inhibition. Several domains of SAMHD1 are critical for LINE-1 regulation. SAMHD1 inhibits LINE-1 retrotransposition in dividing cells. An enzymatic active site mutant SAMHD1 maintained substantial anti-LINE-1 activity. SAMHD1 inhibits ORF2p-mediated LINE-1 reverse transcription in isolated LINE-1 ribonucleoproteins by reducing ORF2p level. Thus, SAMHD1 may be a cellular regulator of LINE-1 activity that is conserved in mammals.

    This works gives an account of evaluation of white blood cell differential counts via computer aided diagnosis (CAD) system and hematology rules. Leukocytes, also called white blood cells (WBCs) play main role of the immune system. Leukocyte is responsible for phagocytosis and immunity and therefore in defense against infection involving the fatal diseases incidence and mortality related issues. Admittedly, microscopic examination of blood samples is a time consuming, expensive and error-prone task. A manual diagnosis would search for specific Leukocytes and number abnormalities in the blood slides while complete blood count (CBC) examination is performed. Complications may arise from the large number of varying samples including different types of Leukocytes, related sub-types and concentration in blood, which makes the analysis prone to human error. This process can be automated by computerized techniques which are more reliable and economical. In essence, we seek to determine a fast, accurate mechanism for classification and gather information about distribution of white blood evidences which may help to diagnose the degree of any abnormalities during CBC test. In this work, we consider the problem of pre-processing and supervised classification of white blood cells into their four primary types including Neutrophils, Eosinophils, Lymphocytes, and Monocytes using a consecutive proposed deep learning framework. For first step, this research proposes three consecutive pre-processing calculations namely are color distortion; bounding box distortion (crop) and image flipping mirroring. In second phase, white blood cell recognition performed with hierarchy topological feature extraction using Inception and ResNet architectures. Finally, the results obtained from the preliminary analysis of cell classification with (11200) training samples and 1244 white blood cells evaluation data set are presented in confusion matrices and interpreted using accuracy rate, and false

    Full Text Available O advento da ISO 24512:2007 suscita discussões muito interessantes em relação ao funcionamento dos sistemas de abastecimento de água em âmbito mundial. No Brasil, a maioria das estações de tratamento de água é convencional de ciclo completo, gerando resíduos complexos e de difícil manejo e disposição. Este trabalho teve como objetivo avaliar de forma crítica a problemática dos resíduos das estações de tratamento de água no Brasil, mediante o estudo da viabilidade de construção e uso de indicadores, tais como aqueles preconizados pela ISO 24512. A grande maioria das estações de tratamento de água analisadas, que refletem um quadro comum no Brasil, não dimensiona a quantidade de resíduos gerados, poucas avaliam suas características e destinam adequadamente esses resíduos, o que dificulta e, em muitos casos, pode impossibilitar o uso de indicadores como ferramentas de gestão. Esse cenário remete ao desafio enfrentado na área de saneamento em relação à gestão dos resíduos em consonância com as normas internacionais.

    The increasing energy challenges faced, in particular, by isolated communities, such as insular communities, call for an integrated, flexible and easy-to-apply methodology aiming at providing a list of renewable energy sources) (RES) projects capable to reduce green house gas (GHG) emissions, satisfy future energy forecasts and reach the objectives of international/national energy directives and obligations, as, for example, the ones set by the Kyoto Protocol by 2010. The EU project EMERGENCE 2010 developed such a methodology that is implemented here in the case study of wind parks in the Dodecanese islands in Greece. The results obtained consist of a final list of financially viable RES wind projects, for which various barriers have been previously identified and assessed. The additional advantages of the proposed methodology is that besides providing as an end result a comprehensive list of RES projects adopted to specific criteria and regional priorities, it also allows space for involving - from early stages - the local community and stakeholders in the decision-making process (participatory planning); in this way, the EMERGENCE 2010 methodology may assist towards the RES promotion and public acceptance, the profitability of RES investments and the regional sustainable development.

    Full Text Available Au tout début de la période romaine, un taux d’arbres inhabituellement élevé a été mis en évidence par la palynologie sur le site de la Source des Roches à Chamalières (Puy-de-Dôme, gisement qui a livré plus de 3500 ex-voto en bois au début des années 70. Durant le second âge du Fer et l’époque romaine, un tel niveau de boisement n’est observé nulle part ailleurs, ni en plaine de Limagne, ni sur le plateau des Dômes. L’hypothèse d’un sanctuaire de plein air, soutenue par Anne-Marie Romeuf qui a dirigé la fouille, se trouve ainsi confortée par l’analyse pollinique, qui permet d’envisager la possibilité de la présence d’un « bois sacré » composé principalement de chênes. La combinaison des données archéobotaniques issues de la palynologie et de la carpologie contribue à renforcer la compréhension du site d’un point de vue paysager et nous renseigne également sur les types d’offrandes végétales associées au dépôt des ex-voto.Unusually high levels of tree pollen were revealed by palynology on the site of the Source des Roches in Chamalières (Puy-de-Dôme for the very beginning of the Roman period. The site had yielded more than 3500 wooden offerings in the early 70s. Such a high density of woodland can be found nowhere else for the Second Iron Age and the Roman period, neither in the plain of Limagne, nor on the plateau of Les Dômes. The hypothesis of an open air sanctuary, first advanced by Anne-Marie Romeuf, director of excavation, is therefore reinforced by the pollen analysis which leads us to consider the possibility that a “sacred grove” made up principally of oaks was present. The correlation of the archaeobotanic data from palynology and paleœthnobotany contributes to the strengthening of the site’s knowledge from the landscape’s point of view. We also have a better understanding of the vegetal offerings associated with the wooden statues.

    Full Text Available Os resíduos sólidos de serviços de saúde (RSSS representam reduzida parcela do total dos resíduos sólidos urbanos gerados diariamente por uma cidade. Considerando a própria origem, parte desses resíduos apresenta riscos e dificuldades especiais em seu manejo, devido especialmente ao caráter infeccioso de alguns componentes. Estasconstatações associadas à necessidade de conhecer a situação dos RSSS do Hospital Universitário Regional de Maringá motivaram a elaboração do estudo. A pesquisa buscou identificar as diferentes fontes geradoras, caracterizar qualitativa e quantitativamente osresíduos gerados determinando a taxa de geração diária. A caracterização foi efetuada mediante a pesagem dos resíduos, acompanhamento das atividades internas do hospital, quanto aos procedimentos de coleta, armazenamento interno e externo e transporte de seus resíduos sólidos. Constatou-se que do total de resíduos gerados, cerca de 53% são considerados contaminados, percentual creditado como não-satisfatório para uma parcela significante de bibliografia consultada.Solid health-care waste (SHCW represents only a small fraction of the total urban solid waste generated daily in a city.

    Yêda Vieira Póvoas Tavares

    Full Text Available O gesso está sendo utilizado em larga escala como revestimento interno de paredes por ser um material barato e de alto desempenho. No entanto, há uma grande geração de resíduo, o que constitui um problema econômico e ambiental. Embora se observe um interesse crescente no uso desse resíduo como revestimento de vedação interna, há um grande desconhecimento a respeito de sua tecnologia de produção, bem como de seu comportamento. O objetivo desta pesquisa é estudar o desempenho desse material através dos ensaios de dureza superficial, resistência à compressão e de aderência, além da apresentação da técnica de execução do revestimento a partir do aproveitamento do resíduo de gesso. Foram realizados ensaios utilizando-se misturas com 0%, 5% e 10% de resíduo com 0,6 mm de diâmetro máximo, e também realizadas visitas técnicas aos canteiros de obras para a avaliação e a determinação da técnica de execução mais apropriada para a aplicação do revestimento. Os resultados mostraram que a adição de resíduos não prejudica excessivamente as propriedades estudadas, sendo admissível até 10% de resíduo de gesso na produção da nova argamassa, respeitando-se as recomendações da técnica construtiva.

    íodo de 1 a 8 dias e 120 no período de 10 a 17 dias de idade. Nos ensaios utilizou-se o delineamento inteiramente casualizado e três tratamentos com cinco repetições de 10 e 8 aves nas respectivas idades. Os tratamentos consistiram de três dietas: uma dieta referência, uma com 30% de farelo de tomate e outra com 20% de farelo de goiaba, ambas substituindo parte da ração referência. Os valores de composição química dos resíduos da goiaba e do tomate variaram quanto à época de coleta. Os resíduos apresentaram composição satisfatória para alimentação de aves, porém com altos teores de fibra bruta. Os valores de energia metabolizável o coeficiente de metabolizabilidade da energia bruta do resíduo da goiaba não sofreram influência da idade das aves. Para o resíduo de tomate os valores de energia metabolizável aparente e coeficiente de metabolização variaram entre as idades. Os valores de energia metabolizável aparente corrigida para pintos de corte de 1 a 8 e de 10 a 17 dias de idade foram de 1.331 e 1.358 kcal/kg para o resíduo de goiaba e de 2.351 e 2.465 kcal/kg para o resíduo de tomate.

    Full Text Available O crescimento populacional tem gerado diversos problemas na sociedade contemporânea. Dentre eles estão o aumento do descarte de resíduos urbanos e a carência de moradia de baixo custo. O objetivo do presente trabalho foi estudar a potencialidade da utilização de dois resíduos sólidos na confecção de pisos flutuantes para redução do ruído de impacto através de parcerias com Furnas Centrais Elétricas e UFG. As amostras foram confeccionadas com o flake de garrafas PET e a raspa de pneus inservíveis aplicados em misturas cimentícias nas proporções de 1:4 e 1:5 (cimento: resíduo. Estas tinham espessuras diferentes sobre as quais tiveram a colocação de um contrapiso móvel com dois tipos de revestimento cerâmico. Para os ensaios foram consultadas a ISO 140-7 quanto aos procedimentos de medição para os níveis de pressão sonora de impacto (L’nT e a ISO 717-2 para a determinação do valor único ponderado (L’nT,w. Dentre os resultados, 5 amostras com PET obtiveram L’nT,w superior às demais amostras. Conclui-se que as amostras com resíduo de PET tiveram desempenho superior às amostras com resíduo de pneu. Contudo, ambos resíduos possuem um uso potencial na aplicação de pisos flutuantes nas proporções estudadas, porém necessitam maiores estudos para aplicação técnica.

    Full Text Available O interesse pela preservação dos recursos naturais e a busca pelo desenvolvimento sustentável tem despertado interesse de um grande número de pesquisadores visando obter materiais de construção não convencionais. Dentre essas possibilidades, destacam-se os resíduos produzidos pela construção civil e pela indústria de beneficiamento de granito, em virtude do volume gerado e os impactos ambientais do seu descarte inadequado. Este trabalho tem como objetivo estudar a durabilidade das argamassas alternativas incorporadas com resíduos de construção civil e da serragem do granito. Para quantificar a durabilidade dos materiais estudados, foram realizados ensaios de envelhecimento natural e ensaios de envelhecimento acelerado através de ciclos de molhagem e secagem, visando simular condições de utilização e avaliar sua degradação. Nos estudos da durabilidade foram utilizados traços de argamassas para alvenaria de elevação, com percentagens de substituição, em peso, da cal por resíduo de 30% e 50%. Os resultados para o envelhecimento natural evidenciaram o comprometimento da durabilidade do material após 60 dias com redução no comportamento mecânico, sendo os melhores resultados para os corpos-de-prova com 30% e 50% de resíduo de construção. No envelhecimento acelerado, para os tratamentos adotados, os resultados evidenciaram a ação da formação de silicoaluminatos de cálcio e potássio que favoreceram um aumento do comportamento mecânico e, além disso, não foi observado o comprometimento da sua durabilidade.The preservation of natural resources and search for sustainable development are increase in interest by the researchers with the aim to obtain knowledge of non conventional materials.

    The effects of carbon particles and bacterial endotoxins on immunological recovery after irradiation were compared in relation to the radioprotective effects of the agents. When mice were injected with 10 mg of carbon particles (sufficient to protect the animals from radiation-induced death) 24 hrs prior to the administration of sheep red blood cells, the recovery of their immune response to the antigen was not significantly affected. Administration of 1 mg of carbon particles caused a slight enhancement of immune response. Previous treatment of animals with endotoxin resulted in a significant suppression of the immune response regardless of irradiation, the degree of suppression depending on the dose given. These results strongly suggest that the radioprotective effect of carbon- or endotoxin-treatment is attributable to the apparent RES-blockade and to the enhancement of hemopoietic recovery rather than to the enhancement of immunological recovery after irradiation.

    Full Text Available O resíduo industrial lama de cal, originado da produção de papel kraft branqueada de eucalipto, apresenta em sua composição quantidade considerável de cálcio (Ca, o que pode contribuir para reduzir o consumo de fertilizantes em plantios florestais. Com o objetivo de avaliar o efeito da lama de cal como fonte de Ca e seus efeitos sobre a disponibilidade de nutrientes e produção de matéria seca da parte aérea de plantas de eucalipto, foram conduzidos dois ensaios em vasos, em casa de vegetação, na área de pesquisa da Klabin Florestal do Paraná. Os solos utilizados foram um Neossolo Quartzarênico órtico (RQo e um Nitossolo Vermelho eutroférrico (NV. Os tratamentos constituíram-se de duas fontes de Ca, calcário dolomítico e lama de cal, e de uma testemunha, sendo identificados como: RQo testemunha, RQo calcário e RQo lama de cal; e NV testemunha, NV calcário e NV lama de cal. O delineamento experimental utilizado foi inteiramente casualizado, com quatro repetições. Para tanto, plantas de Eucalyptus saligna foram mantidas por 126 dias em vasos. Quantificou-se a produção de matéria seca e realizaram-se as análises de folhas e dos solos, por ocasião da coleta das plantas. Os dados revelaram que tanto a adição de calcário dolomítico quanto a lama de cal promoveram o fornecimento de Ca para as plantas de eucalipto, proporcionando aumentos na produção de matéria seca. Os teores de Ca e Na nas folhas de eucalipto foram acrescidos com a adição do resíduo ao solo, em comparação com o tratamento com calcário dolomítico, enquanto os teores de N, P, K e S foram semelhantes. As plantas cultivadas nos tratamentos RQo testemunha e RQo lama de cal apresentaram teores foliares de Mg abaixo da faixa considerada adequada. A adição de lama no solo elevou o pH e as concentrações de Ca e de Na, reduziu o Al trocável e não influenciou na disponibilidade de Mg, fato que pode proporcionar deficiência de Mg às plantas, em

    Giusti, Christian

    2014-05-01

    The starting point of this essay is a question from a school teacher who came in contact with me via my photo gallery online. His question, "What is the origin of the Roc de Murviel?" actually covers three or four separate problems, and requires to devise simple and specific comparisons in order to help children of 8 years old to understand a bunch of difficult and abstract concepts. But, in contrast, Carboniferous marine sedimentary deposits of the so-called unit "Klippen of Cabrières" are known of geologists worldwide, due to the presence of a Global boundary Stratotype Section and Point (GSSP) located not far from the "Roc de Murviel", the "La Serre" section, where is defined the base of the Carboniferous System, Mississippian Sub-System and Tournaisien Stage. In this case, to remind how the conceptions about the formation of the "Klippen of Cabrières" evolved may serve as an introduction to the explanation of syntectonic sedimentation and to the history of the concept of thrust nappe for the well-trained public as well as academics or engineers not experts in the specificities of regional geology. Difficulty (at least in France) will come from the scarcity of naturalists, a species in danger of extinction, and from the small number of historians concerned by the natural sciences. At the public school, the first method is to decompose the problem into independent issues (Cartesian reductionism) such as: nature and age of the rock? mode of sedimentation? part of an ancient mountain chain? existence as a landform in the current landscape? Concerning the specific question of geological time, because most children of this age do not yet know how to read the time, a second method is to replace the model of the clock (the entire history of the planet Earth reduced to one year) by the metaphor of either the staircase or the ladder, both adapted from the international stratigraphic scale. A third method is to use the concept of "toolbox" for each sub-disciplines or

    nos pressupostos teóricos sobre o tema de estudo. Para avaliar e conhecer o programa de coleta de resíduos na zona rural existente no município, realizou-se uma analise documental, utilizando como fonte o Plano Diretor do município (2009. Os resultados constataram que grande parte dos resíduos domésticos produzidos na zona rural do município pesquisado não recebe a destinação correta de acordo com normas básicas de prevenção à poluição ambiental. Constatou-se também que a maioria da população pesquisada não recebe orientações sobre a forma de tratamento adequado a ser dado aos resíduos produzidos e também não é incentivada para tais ações. Quanto ao programa de coleta de resíduos, este parece não estar sendo eficiente, pois ficou evidente que o referido programa não atende grande parte das comunidades na zona rural. De acordo com a opinião dos usuários, o programa não teve uma boa avaliação, pois 55,8% dos usuários apontaram que o mesmo como ruim e regular.

    Full Text Available Atualmente existe uma grande preocupação por parte das indústrias com a disposição dos resíduos gerados ao longo do processo produtivo. No setor mineral não é diferente, pois este gera grande volume de resíduos. Verificou-se que a indústria de beneficiamento do caulim descarta grandes volumes de resíduo constituído basicamente de caulinita, mica muscovita e quartzo, ocasionando um impacto ambiental, o que tem justificado os esforços de pesquisas para sua solução. Deste modo, foi estudado o efeito da incorporação de um resíduo proveniente do beneficiamento de caulim sobre as propriedades físicas e tecnológicas de revestimentos cerâmicos de alta qualidade. O objetivo é caracterizar e estudar o processamento do resíduo proveniente da indústria de beneficiamento do caulim com adição de uma "massa padrão", fornecida por uma indústria de revestimento cerâmico. O resíduo foi caracterizado por meio de análises de difração de raios X, fluorescência de raios X e determinação do tamanho de partículas. Foram realizados ensaios de absorção de água, porosidade aparente, retração linear após queima, massa específica aparente e tensão de ruptura à flexão, para determinação das propriedades tecnológicas destes materiais. Os resultados mostram que o resíduo estudado pode ser considerado como matéria-prima de grande potencial para a indústria de pisos e revestimentos cerâmicos.There is a great concern by the industrial area on the disposal of waste generated during the production process.

    Full Text Available Twenty-five years after the beggining of the policies of adjustment and liberalization which is the situation of the food crops in the countries of the Sahel? The balance-sheet is approached by contrasting the cereals sub sector, facing to a very strong control by the State, and the onion whose growth is related to the increase in the demand of the great urban centers. The increase in the production of cereals was accompanied by deep changes in the structures. The market became more efficient and better integrated on a regional scale. But, the level and the instability of the prices of cereals increased, making difficult the provisioning of the poor. Clear differences in trajectories appear. Mali, which implemented a policy of reforming cereals market and successful the revival of rice sector, must manage at the same time the improvement of the competitiveness of its cereals and the access to cereals of the low incomes consumers. Niger must face the increase in the vulnerability of a great part of the rural households. The production of onion experienced a spectacular increase in Senegal after the devaluation of franc FCA in response to the urban market. That of Niger intended mainly for the close countries progressed more slowly. But in both cases, the regulation of the European onion imports constitutes a paramount stake.

    Full Text Available Although the countries of the Western Balkans are mostly electrified, there are still regions which do not have access to the electricity network or where the network capacity is insufficient. For the most part such areas are under special care of the state (i. e. underdeveloped, devastated by war, depopulated, on islands or in mountainous regions. Since the decentralized energy generation covers a broad range of technologies, including many renewable energy technologies that provide small-scale power at sites close to the users, such concept could be of interest for these locations. This paper identifies the areas in Western Balkans where such systems could be applied. Consideration is given to geographical locations as well as possible applications. Wind, hydro, solar photovoltaic, and biomass conversion systems were taken into consideration. Since the renewable energy sources data for Western Balkans region are rather scarce, the intention was to give a survey of the present situation and an estimate of future potential for decentralized energy generation based on renewable energy sources. The decentralized energy generation based on renewable energy sources in Western Balkans will find its niche easier for the users that will produce electricity for their own needs and for the users located in remote rural areas (off-grid applications.

    Full Text Available Durant la dernière décennie, peu d’études se sont penchées sur l’utilisation que font les journalistes politiques d’Internet et des réseaux socionumériques, particulièrement à l’extérieur des États-Unis et du contexte spécifique des campagnes électorales. Traditionnellement, un pan de la littérature en communication conçoit l’actualité politique comme une construction, négociée principalement entre les journalistes et les autorités politiques. Or, les sources d’information des journalistes tendent à se diversifier ; Internet fournit désormais aux acteurs politiques, médiatiques et citoyens l’occasion d’interagir et de négocier la construction de l’actualité publiquement, en temps réel. En ce sens, cet article explore comment les journalistes politiques québécois utilisent Internet, et plus spécifiquement Twitter, dans leurs pratiques et leurs discours professionnels, à partir d’une analyse de contenu quantitative et qualitative des messages diffusés par la presse parlementaire durant une période de deux semaines. D’une part, nos analyses montrent la persistance de pratiques caractéristiques des médias de masse et l’émergence de nouvelles façons de faire. Généralement, les journalistes parlementaires dialoguent peu et sont enclins à conserver leur rôle de gardien de l’information (gatekeeper sur Twitter, diffusant principalement leur propre travail ou celui d’autres journalistes. De plus, les sources politiques officielles continuent à occuper une place prépondérante dans leur couverture. Cependant, le rapport des journalistes parlementaires au temps se transforme. Une partie très importante de leur production consiste à communiquer instantanément de l’information fragmentaire sur un événement politique, laissant peu d’espace et de temps à la vérification de l’information. D’autre part, nos données révèlent une diversité dans les usages de Twitter chez les

    Full Text Available RESUMO - Os resíduos quando disposto de forma incorreta, sem qualquer tratamento, pode poluir o solo, alterando suas características físicas, químicas e biológicas, se tornando também em um problema de ordem estética e uma ameaça à saúde pública. A destinação inadequada dos resíduos sólidos proveniente das diversas atividades humanas é, atualmente, um dos significativos problemas enfrentado pela administração pública no Brasil e em países em desenvolvimento. Este trabalho tem por objetivo diagnosticar o atual processo de gerenciamento dos resíduos sólidos urbanos realizados no município de Pombal – PB, e propor o gerenciamento dos mesmos de maneira mais adequada diante das condições locais. O método de diagnosticar fundamentou-se num levantamento bibliográfico, entrevista ao órgão competente e a aplicação de questionários a população, em todos os bairros do município. Com o resultado deste estudo foi perceptível que a maioria da população necessita ser informada sobre as questões ambientais, para que desta forma gerencie adequadamente seus resíduos. O poder público municipal já está tomando algumas providencias para diminuir os impactos gerados pela falta de um correto gerenciamento dos seus resíduos, mas alguns pontos ainda precisam ser levados em consideração, como trabalhar principalmente a conscientização da população.Palavras chave: Destino final, Conscientização, Poder publico. 

  2. The Rock Engineering System (RES) applied to landslide susceptibility zonation of the northeastern flank of Etna: methodological approach and results

    2015-04-01

    Ground deformations in the northeastern flank of Etna are well known. Despite only a few landslide events have been documented, these have significantly involved and damaged lifelines and buildings. These events are mainly related to the activity of the volcano-tectonic structures and associated seismicity, as in the case of the 2002 reactivation of the Presa landslide during an increased activity of the Pernicana fault system. In order to highlight the areal distribution of potentially unstable slopes based on a detailed, site-specific study of the factors responsible for landslide, and to ultimately contribute to risk management, a landslide susceptibility analysis of the northeastern flank of Etna in the Pernicana area was carried out, and a susceptibility map at 1:10.000 scale was produced, extending over an area of 168 km2. Different methods are proposed in the literature to obtain the regional distribution of potentially unstable slopes, depending on the problem scale, the slope dynamic evolution in the geological context, and the availability of data. Among semi-quantitative approaches, the present research combines the Rock Engineering System (RES) methodology with parameter zonation mapping in a GIS environment. The RES method represents a structured approach to manage a high number of interacting factors involved in the instability problem. A numerically coded, site-specific interaction matrix (IM) analyzes the cause-effect relationship in these factors, and calculates the degree of interactivity of each parameter, normalized by the overall interactivity of the system (weight factor). In the specific Etna case, the considered parameters are: slope attitude, lithotechnical properties (lithology, structural complexity, soil and rock mass quality), land use, tectonic structures, seismic activity (horizontal acceleration) and hydrogeological conditions (groundwater and drainage). Thematic maps are prepared at 1:10.000 scale for each of these parameters, and

    Full Text Available Les polymères auto-renforcés à cristaux liquides (PARCL sont des matériaux dont les molécules, des polymères organiques, sont susceptibles de s'auto-orienter les unes par rapport aux autres. Cette propriété leur confère des caractéristiques mécaniques proches de celles des acier: pour des poids plus faibles sans qu'il soit nécessaire d'avoir recours à des fibres renforçantes. Il existe deux types de PARCL: ceux pouvant s'orienter en solution, qualifiés de lyotropiques, et ceux pouvant s'orienter à l'état fondu, appelés thermotropiques. Des fibres en poly (p-phénylène térephtalamide PPT, PARCL de type lyotropique, sont disponibles commercialement et connaissent déjà de nombreuses applications. Les PARCL thermotropiques n'existent pas encore sur le marché mais sont porteurs de nombreux espoirs car ils sont susceptibles d'être moulés et donc de prendre les formes les plus diverses, ce qui n'est pas le cas de ceux de type lyotropique. Self-reinforcing liquid-crystal polymers are materials in which the molecules, i. e. organic polymers, are capable of orienting themselves in relation to one another. This property gives them mechanical characteristics close to those of steels yet of much less weight without having to use reinforcing fibers. There are two types of self-reinforcing liquid-crystal polymers: (i those capable of orienting themselves in solution, called Iyotropic, and (ii those capable of orienting themselves in a molten state, called thermotropic. Poly (p-phenylene terephthalamide fibers, self-reinforcing liquid-crystal polymers of the Iyotropic type, are commercially available and have already found numerous applications. Thermotropic self-reinforcing liquid-crystal polymers are not yet on the market but seem to be very promising because they are capable of being molded and hence of taking on a wide variety of shapes, which is not the case of those of the lyotropic type.

    Les travaux de recherches sur la sécurité transfusionnelle en Afrique sub-saharienne sont peu nombreux, souvent limités à des initiatives locales avec des conclusions difficilement représentatives de cette région. Le Groupe de recherches transfusionnelles en Afrique sub-saharienne francophone a été créé en mai 2007 avec pour objectif de développer des stratégies globales d’amélioration de la sécurité transfusionnelle mais adaptables à la situation de chaque pays. Les activités du Groupe à ce jour ont porté essentiellement sur l’obtention de données épidémiologiques et de laboratoire sur la transfusion sanguine et à proposer des stratégies de sécurité transfusionnelle dans le domaine des infections transmissibles par la transfusion. Pour mener à bien ces activités de recherche, le Groupe travaille en étroite collaboration avec les Centres nationaux de transfusion sanguine (CNTS), les Centres régionaux de transfusion sanguine (CRTS), les banques de sang hospitalières (BSH) et les postes de collecte de sang. Pour les 5 premières années, quatre priorités de recherche ont été identifiées: (i) des études descriptives sur les caractéristiques des donneurs de sang et des centres de transfusion; (ii) une estimation du risque résiduel post-transfusionnel des principales infections virales transmissibles par la transfusion; (iii) une analyse des stratégies de sélection médicale des donneurs de sang; et (iv) une description des stratégies de dépistage des ITT et une description du système d’assurance qualité externe existant. Durant cette période, sept projets ont été mis en œuvre au niveau national et publiés et cinq études multicentriques ont été réalisées et publiées.

    Precipitation is a key forcing variable in hydrological modeling of floods and being able to accurately observe precipitation is extremely important in mitigating flood impacts. The Global Precipitation Measurement (GPM) Mission, launched in Feb 2014 also presents an opportunity for high-quality real-time precipitation data and improved flood warnings. The PERSIANN-CCS developed by the scientists at the Center for Hydrometeorology and Remote Sensing (CHRS) at the University of California, Irvine is one algorithm integrated in the IMERG of PMM/GPM. In this research, the high resolution coupled hydrologic/hydraulic model named HiResFlood-UCI was applied to simulate the historical 2008 Iowa flood in the Cedar River basin. HiResFlood-UCI is a coupling of the NWS's distributed hydrologic model HL-RDHM and the hydraulic model BreZo developed by the Computational Hydraulics Group at the University of California, Irvine. The model was forced with the real-time PERSIANN-CCS and NEXRAD Stage 2 precipitation data. Simulations were evaluated based on 2 criteria: hydrographs within the basin and the areal extent of the flooding. Streamflow hydrographs were compared at 7 USGS gages, and simulated inundation maps were evaluated using USDA AWiFS 56m resolution areal flood imagery. The results show reasonable simulated hydrographs compared to USGS streamflow observations when simulating with PERSIANN-CCS and NEXRAD Stage 2 as forcing inputs. The simulation driven by NEXRAD Stage 2 slightly outperforms the PERSIANN-CCS simulation as the latter marginally underestimated the observed hydrographs. The simulation in both cases shows a good agreement (0.672 and 0.727 CSI for Stage 2 and PERSIANN-CCS simulations respectively) with the AWiFS image over the most impacted area in the Cedar Rapids region. Since the PERSIANN-CCS simulation slightly underestimated the discharge, the probability of detection (0.925) is lower than that of the Stage 2 simulation (0.965). As a trade-off, the false

    Mental health problems, particularly anxiety and mood disorders, are prevalent in the setting of humanitarian emergencies, both natural and man-made disasters. Evidence regarding best strategies for therapeutic interventions is sparse. Médecins Sans Frontières has been providing mental health services during emergencies for over two decades, and here we compare data from four programs. In China, 564 patients were followed for an average of 7 sessions after a major earthquake. The most common diagnoses were PTSD and other anxiety disorders. Between program entry and exit, the median global assessment of functioning increased from 65 to 80. At program entry, 58% were considered moderately, markedly or severely ill; a proportion which fell to 14% at program exit. In Colombia in the setting of chronic violence, 2411 patients were followed for a median of two sessions. Anxiety disorders and major depression were the most common diagnoses, and 76% of patients were moderately or severely ill at program entry. 91% had symptomatic improvement at program exit. In Gaza, 1357 patients were followed for a median of 9 sessions; a majority was under age 15. PTSD and other anxiety disorders were the most common diagnoses, and 91% were moderately or severely ill at entry. 89% had improved symptoms at program exit. In the West Bank, the 1478 patients had similar characteristics to those enrolled in Gaza. 88% were moderately or severely ill at entry; 88% had improved at exit. It was feasible to implement brief yet effective mental health interventions in a wide variety of humanitarian contexts - post-natural disaster, during acute violent conflict and during chronic violent conflict. The most common diagnoses were PTSD, other anxiety disorders and mood disorders. The use of local specially-trained counselors who were focused on coping skills and improving functionality over a brief time period, likely contributed to the symptomatic improvement seen in a large majority of patients

    The share of renewable energy resources for electricity production, in a distributed setting (DG-RES), increases. The amount of energy transported via the electricity grid by substitution of fossil fuels for mobility applications (electric vehicles) and domestic heating (heat pumps) increases as well. Apart from the volume of electricity also the simultaneity factor increases at all grid levels. This poses unprecedented challenges to capacity management of the electricity infrastructure. A solution for tackling this challenge is using more active distribution networks, intelligent coordination of supply and demand using ICT and using the gas distribution network to mitigate electricity distribution bottlenecks. In the EU FP6 Energy Program Integral project, a large scale heterogeneous field test has been designed for application of the software agent based PowerMatcher technology. The test is conducted in a suburb of Groningen, Hoogkerk, and entails approximately 30 homes with either a 'dual fuel' heating system (electrical heat pump with gas-fired peak-burners) or a micro-CHP. Homes also may have PV. Furthermore, a wind production facility and nodes with electricity chargers for EVs and electricity storage are part of the Virtual Power Plant cluster, constructed in this way. Domestic heating systems have intrinsic operational flexibility in comfort management through the thermal mass of the dwellings. Furthermore, the field test comfort systems are equipped with possibilities for hot water storage for central heating as well as for tap-water. Finally, having additional gas-fired heating capacity for electrical heat pumps adds to increasing flexibility by switching the energy source dependent on the status of the electricity grid. Purpose of the field test is using this flexibility to react to phenomena in the electricity system. From a commercial perspective, the aggregated cluster reacts on small-time scale events like real-time portfolio imbalance

  12. In Search of the ‘New Informal Legitimacy’ of Médecins Sans Frontières

    Calain, Philippe

    2012-01-01

    For medical humanitarian organizations, making their sources of legitimacy explicit is a useful exercise, in response to: misperceptions, concerns over the ‘humanitarian space’, controversies about specific humanitarian actions, challenges about resources allocation and moral suffering among humanitarian workers. This is also a difficult exercise, where normative criteria such as international law or humanitarian principles are often misrepresented as primary sources of legitimacy. This essay first argues for a morally principled definition of humanitarian medicine, based on the selfless intention of individual humanitarian actors. Taking Médecins Sans Frontières (MSF) as a case in point, a common source of moral legitimacy for medical humanitarian organizations is their cosmopolitan appeal to distributive justice and collective responsibility. More informally, their legitimacy is grounded in the rightfulness of specific actions and choices. This implies a constant commitment to publicity and accountability. Legitimacy is also generated by tangible support from the public to individual organizations, by commitments to professional integrity, and by academic alliances to support evidence-based practice and operational research.

    Sheather, Julian; Shah, Tejshri

    2011-03-01

    Médecins Sans Frontières (MSF) is an independent medical humanitarian organisation working in over 70 countries. It has provided medical assistance for over 35 years to populations vulnerable through conflict, disease and inadequate health systems. Medical ethics define the starting point of the relationship between medical staff and patients. The ethics of humanitarian interventions and of research in conflict settings are much debated. However, less is known about the ethical dilemmas faced by medical humanitarian staff in their daily work. Ethical dilemmas can be intensified in humanitarian contexts by insecure environments, lack of optimum care, language barriers, potentially heightened power discrepancies between care providers and patients, differing cultural values and perceptions of patients, communities and medical staff. Time constraints, stressful conditions and lack of familiarity with ethical frameworks can prevent reflection on these dilemmas, as can frustration that such reflection does not necessarily provide instant solutions. Lack of reflection, however, can be distressing for medical practitioners and can reduce the quality of care. Ethical reflection has a central role in MSF, and the organisation uses ethical frameworks to help with clinical and programmatic decisions as well as in deliberations over operational research. We illustrate and discuss some real ethical dilemmas facing MSF teams. Only by sharing and seeking guidance can MSF and similar actors make more thoughtful and appropriate decisions. Our aim in sharing these cases is to invite discussion and dialogue in the wider medical community working in crisis, conflict or with severe resource limitations.

    Full Text Available O volume de resíduos gerado pela mineração e o beneficiamento mineral vêm se intensificando a cada dia, em virtude do aumento da demanda causado pelo crescimento da economia mundial. As indústrias do beneficiamento do caulim e da serragem do granito são importantes segmentos econômicos do Estado da Paraíba, entretanto produzem enormes quantidades de resíduos. Assim, este trabalho tem por objetivo caracterizar os resíduos do beneficiamento do caulim e da serragem do granito e avaliar a viabilidade de sua co-utilização para produção de blocos e telhas cerâmicos. Os resíduos foram caracterizados através da determinação de sua composição química e mineralógica, pelo uso de difração de raios X e análise térmica diferencial e gravimétrica, distribuição e tamanho de partículas e análise morfológica por microscopia eletrônica de varredura. Foram formuladas composições contendo os resíduos e confeccionados corpos de prova por extrusão. Os corpos de prova foram queimados e em seguida determinou-se sua absorção de água e módulo de ruptura à flexão. Pode-se observar que o resíduo do caulim é constituído por caulinita, mica e quartzo, que o resíduo de granito é constituído por quartzo, mica, albita e calcita e, que os resíduos apresentam distribuições granulométricas significativamente diferentes. Concluiu-se também que é possível a incorporação de até 50% de resíduo em formulações para produção de blocos e telhas cerâmicas e que a co-utilização do resíduo de granito e de caulim possibilita obter propriedades físicas superiores às observadas nos corpos de prova com incorporação de apenas resíduo de caulim.The amount of wastes generated by the miner and mineral processing industries has increasing day by day due to the high demand cause by the global economy grow up. The processing kaolin ad sawing granite industries are important economic segments in the state of Paraíba, but generate

    Full Text Available A geração dos resíduos sólidos urbanos (RSU no Brasil vem aumentando ao longo do tempo, com alterações na qualidade do resíduo, o que levanta discussões a respeito do gerenciamento e da importância em se destinar estes resíduos adequadamente. Atualmente as questões que envolvem a gestão dos RSU têm enfoque central no cumprimento de políticas públicas. A partir da implementação efetiva da Política Nacional de Resíduos Sólidos (PNRS - lei nº 12.305/2010 é que se esperam mudanças no panorama dos resíduos sólidos no Brasil. Por conta disso, este trabalho faz um levantamento bibliográfico que tem como objetivo abordar aspectos sobre os RSU no Brasil, considerando aqueles esperados para acontecer no setor público após a implementação da PNRS. Os dados apresentados e discutidos permitiram entender a evolução da gestão dos RSU no Brasil e alguns desafios para o cumprimento das determinações da PNRS, como, por exemplo, a expansão da coleta e tratamento dos RSU, o papel mais ativo da sociedade nos processos que envolvem a separação dos resíduos e a dificuldade da erradicação de lixões e sua substituição por aterros sanitários. Em geral, apesar de terem ocorrido melhoras no gerenciamento dos RSU, estas não foram suficientes para que as mudanças propostas pela PNRS fossem cumpridas e para que se estabeleça uma gestão integrada de RSU mais eficaz e sustentável tanto ao meio ambiente quanto à sociedade, denotando a emergência de soluções estruturais no setor de gerenciamentos dos RSU no Brasil.

    Full Text Available Une première caractérisation des truites de mer des rivières du Nord de l'Espagne (Asturies est réalisée à partir de l'analyse de la structure de taille et d'âge, ainsi que celle de l'alimentation et des paramètres reproducteurs des poissons adultes. Les truites proviennent des captures réalisées à la ligne (de juin à août sur les rivières Cares et Narcea et par pêche électrique sur les zones de frayères du Narcea durant la saison de reproduction (novembre à janvier. Les truites de mer échantillonnées durant la saison de pêche ont une structure d'âge semblable sur les deux cours d'eau. Environ 85% des individus sont restés deux ans en eau douce avant de descendre en mer, et plus de 95% d'entre eux appartiennent aux classes d'âge de mer 0 + et 1 + . L'importance relative des poissons de 0 + de mer (finnock est légèrement plus élevée dans le Cares (68% que dans le Narcea (51 %. Le rapport des sexes est en faveur des femelles, quelle que soit la classe d'âge de mer. La structure d'âge marin des truites capturées en période de reproduction ne diffère pas de celle observée durant la saison de pêche, bien que montrant une haute proportion de 0 + de mer (32% de l'ensemble des poissons matures. Le taux de maturation chez les truites de 0 + de mer est particulièrement élevé ( 81% parmi les femelles et 100% chez les mâles et tous les individus des autres classes d'âge de mer sont matures. Le nombre d'oeufs (de 571 à 2086 oeufs par femelle et l'index gonadosomatique sont positivement corrélés à la taille et à l'âge de mer des femelles. La truite de mer se nourrit activement en eau douce durant la remontée estivale, puisque 81 % des estomacs examinés étaient pleins. Elle consomme principalement des Epheméroptères, des Diptères et des Trichoptères, mais son alimentation inclut également des proies d'origine terrestre, essentiellement des Arthropodes.

    Full Text Available A taxa de mineralização do nitrogênio (N varia de um resíduo orgânico para outro, evidenciando-se dependente da sua composição química e interação do material orgânico com o solo. Este estudo foi realizado com o objetivo de avaliar a dinâmica de mineralização de N de resíduos orgânicos incubados em Latossolos. O experimento foi conduzido no período de julho de 2007 a abril de 2008, sendo incubadas amostras de estercos, lodos, compostos, substrato e turfa em areia lavada, Latossolo Vermelho-Amarelo (LVA e Latossolo Vermelho distroférrico (LVdf, com 240 e 670 g kg-1 de argila, respectivamente. O N mineralizado foi avaliado medindo-se os teores de N-NH4+ e N-NO3- em lixiviados coletados aos 15, 30, 45, 60, 75, 90, 120, 150, 180, 210, 240 e 270 dias de incubação. A mineralização de N ocorreu a maiores taxas nos períodos iniciais de incubação. O N mineralizado (33 a 199,2 mg kg-1 após 270 dias de incubação é regulado pelos teores de N total e de carbono solúvel em água dos resíduos orgânicos. Independentemente do meio utilizado para incubação, os estercos de galinha e de codorna propiciaram os maiores teores de N mineralizado nos Latossolos. À exceção dos estercos de galinha e codorna, há imobilização líquida de N no LVA; mineralização líquida de N é verificada no LVdf, para todos os resíduos orgânicos. Em relação às formas de N disponibilizadas pelos resíduos, predomina o N-nitrato, sendo a proporção N-nítrico/N-amoniacal dependente da mistura solo-resíduo estudada.

    Full Text Available Depuis le stade des études préliminaires jusqu’à la réalisation des travaux, un projet routier fait l’objet de décisions successives (opportunité, budget, tracé…, selon une procédure progressive et réglementée. Cette succession de choix s’insère dans un faisceau de contraintes environnementales, techniques et financières. Ceci rend le processus décisionnel complexe, du fait notamment de la multiplicité des acteurs potentiellement impliqués. Dans ce contexte, la contribution de chercheurs peut consister à fournir des méthodes, permettant d’apporter un éclairage sur les conséquences potentielles en terme de développement durable, des décisions successives prises depuis la conception d’un projet routier jusqu’à sa réalisation. Dans cette perspective, une analyse des critères décisionnels propres à chacun des acteurs au sein du processus décisionnel, est nécessaire. L’objectif de cet article est d’analyser sur quels enjeux généraux reposent les critères décisionnels intervenant dans les différents choix successifs d’un projet routier. Il s’agit d’une part d’effectuer l’examen détaillé du processus décisionnel régi par des éléments factuels imposés par la réglementation, et d’autre part de mieux appréhender les critères non réglementaires, propres à chaque acteur sous la forme de témoignages. Sur la base de la synthèse réalisée, une discussion propose ensuite de mettre en perspective l’analyse effectuée au regard des enjeux environnementaux et de concertation. L’analyse montre la difficulté à définir une liste de critères décisionnels relatifs à la prise en compte des enjeux du développement durable. D’autre part, la réflexion menée met en lumière la meilleure prise en compte des enjeux environnementaux lorsqu’une démarche de concertation est menée en amont du projet, ce qui va au-delà du simple cadre réglementaire et reste à l’initiative de la ma

    Full Text Available Este trabalho apresenta o gesso na construção civil, suas aplicações, características e o desperdício associado. É exposta a legislação brasileira pertinente ao gerenciamento dos resíduos sólidos na construção, e mais especificamente as resoluções CONAMA 307/02 e 431/11, em que o resíduo de gesso passou a ter uma reclassificação quanto a sua destinação. Assim, esse passou a ser considerado um material passível de reutilização e reciclagem. Dessa forma, o objetivo do trabalho foi investigar a viabilidade técnica de aproveitamento de resíduos de gesso como matéria-prima para materiais de construção, no caso, pela incorporação deste em telhas. Assim, é feita uma descrição dos tipos de telhas, suas características e métodos de fabricação, como também a exposição de dois tipos de telhas recicladas. É descrito também o albedo, associado com o benefício de telhados brancos na redução da temperatura dentro das edificações nos dias de maior calor. Foi feita uma lista com as formas e cobrimentos possíveis para a adaptação do gesso na telha, e a partir de características favoráveis às telhas foi escolhido o modelo a ser detalhado, a partir de uma matriz avaliativa. O modelo escolhido foi o Colonial Gigante, com capa polimérica feita de resíduo de PET (politereftaleno de etileno envolvendo o resíduo de gesso. Um modelo 3D foi desenvolvido, e a telha foi nomeada de Telha GePET. Foram definidas em laboratório a umidade e a massa específica aparente e unitária do resíduo de gesso. Diversas características da telha foram descritas, como suas dimensões, massa, fonte de matéria-prima, produção, instalação no telhado, manutenção e durabilidade, o descarte após sua vida útil, o albedo, o isolamento térmico e o valor da telha. Concluiu-se que é possível a fabricação de uma telha com resíduos de gesso, juntamente com o resíduo de PET, tornando-a um produto mais sustentável e 100% reciclável.

Os resultados mostraram que tais resíduos, constituídos basicamente por bainhas e pedaços tenros de colmo, apresentaram elevados teores de proteína (131,4 g/kg, açúcares (115,3 g/kg, fibras (235,4 g/kg e ácido cianídrico (213 mg/kg. Essa concentração de ácido cianídrico pode causar efeito tóxico em animais, devendo-se, portanto, eliminá-lo, adotando o mesmo procedimento utilizado para a fração comestível do broto, o qual se resume no cozimento em água fervente durante 20 minutos. Após esse tratamento, os resíduos de broto de bambu podem ser utilizados como alimento animal.The mineral and bromatologic characterization of bamboo shoot residues (Dendrocalamus giganteus Munro were determined as animal food. The results showed that the bamboo shoot residues (sheaths and pieces of soft culms presented hight contents of protein (131.4 g/kg, sugars (115.3 g/kg, fibers (235.4 g/kg and hydrocyanic acid (213 mg/kg. This hydrocyanic acid concentration can be toxic for animals, then this cyanogenic componed must be eliminated using boiling water during 20 minutes. This treatment is similar to the treatment used for edible parts of bamboo shoot. After this treatment for hydrocyanic acid elimination the bamboo shoot residues can be used as animal food.

O trabalho teve como objetivo avaliar aeficiência do processo Fenton no tratamento de lixiviado gerado em aterros sanitários de resíduos sólidos urbanos. As amostras delixiviado foram coletadas no aterro controlado do município de Santa Maria – RS. No experimento foram testados cincotratamentos com diferentes proporções de reagentes (H2O2 e FeSO4 TH2O2/FeSO4: T0,8, T2,0, T3,0, T4,0 e T6,0. Pelos resultados doexperimento com processo Fenton verifica-se uma eficiência média na remoção da demanda química de oxigênio (DQO de47,9%, na turbidez de 53,0% e na cor de 70,7%. Os valores médios da demanda bioquímica de oxigênio (DBO e dacondutividade elétrica aumentaram em 31,3% e 27,1%, respectivamente. No tratamento T0,8 constatou-se a maior remoção daDQO e o maior aumento da biodegradabilidade. O processo Fenton aplicado no tratamento de lixiviado reduz a DQO e aumenta aDBO, em outras palavras, aumenta a biodegradabilidade do efluente.

    Full Text Available Le dépôt des salissures marines sur les ouvrages immergés est influencé par plusieurs facteurs et il entraîne des conséquences néfastes, en particulier pour la maintenance des supports de plates-formes de production du pétrole en mer et pour la consommation d'énergie requise pour la propulsion des navires. Divers moyens de lutte antisalissure ont été envisagés parmi lesquels les peintures marines antisalissures occupent une place de choix. Ces peintures contiennent, en général, un composé métallique toxique envers les organismes marins d'origine animale ou végétale et différents mécanismes d'action ont été proposés. Les dérivés organostanniques sont des agents biocides très efficaces et lorsqu'ils sont liés chimiquement sur un polymère, en particulier sous forme de greffons, on obtient un contrôle amélioré de leur lixiviation dans la phase aqueuse et par conséquent la durée de vie du revêtement antisalissure est prolongée. La synthèse de polymères comportant un cation organostannique toxique peut être effectuée, soit par la polymérisation ou la copolymérisation de monomères insaturés organostanniques, soit par la réaction chimique de composés organostanniques avec un substrat polymère comportant des groupes fonctionnels appropriés. Les avantages et les inconvénients de diverses formulations de peintures à base de dérivés organostanniques sont discutés. Marine fouling deposits on submerged structures are influenced by several factors and bring about harmful consequences, especially with regard to offshore oil-production platform structures and for the energy consumption required for ship propulsion. Various antifouling methods have been considered, including antifouling marine coatings in particular. Such paints generally contain a metallic compound which is toxic with regard to marine organisms of animal or vegetable origin, and various action mechanisms have been proposed. Organo

    Directory of Open Access Journals (Sweden)

    Joel Vieira Baptista Junior

    2013-12-01

    Full Text Available Neste trabalho são discutidos os principais aspectos relacionados à geração de resíduos da construção civil, sob ponto de vista de sustentabilidade das edificações. Esse conceito exige, das novas construções, a adoção de projetos criativos e eficientes, com soluções adequadas para as diversas fases de vida da obra, incluindo a previsão do reaproveitamento e descarte de materiais ao fim de sua vida útil. Um dos problemas atuais da gestão de resíduos da construção civil é que a segregação dos materiais por classe, visando à sua posterior reciclagem ou descarte, só acontece na cidade do Rio de Janeiro em grandes obras com canteiros instalados, embora mais da metade da quantidade produzida seja proveniente de pequenas obras com resíduos descartados em caçambas de rua ou simplesmente lançados em vias públicas ou terrenos baldios. É sugerido um plano de gestão circular, especialmente voltado para os pequenos geradores, com obrigatoriedade de segregação dos materiais, instalação de pontos de recolhimento pelos bairros da cidade e implantação de centros de tratamento de resíduos da construção civil, operados por associações de catadores, com objetivo de produção de materiais reciclados. O sucesso da proposta depende da efetiva participação de todos os agentes envolvidos no processo, como o poder público, proprietários, empresas e demais profissionais da indústria da construção civil.

Repicou-se uma plântula de pupunheira por recipiente (sacos plásticos de polietileno preto de 8 x 20 cm, volume 1,1 L, os quais foram preenchidos com os diferentes substratos. Foram determinadas mensalmente as variáveis diâmetro do coleto, altura da haste, número de folhas e taxa de crescimento relativo e, após 180 dias da repicagem, os valores SPAD (Soil and Plant Analysis Development, dinâmica da assimilação de CO2, da transpiração e da condutividade estomática. O resíduo de mineração de areia puro como substrato não proporcionou mudas de qualidade, visto que esse material apresenta alta densidade e baixa granulometria. Seu uso pode ser indicado como um dos componentes de substratos, pois as plantas que cresceram nas misturas de resíduo e casca de arroz carbonizada apresentaram resultados semelhantes ao do considerado padrão.

    Full Text Available Les ressources forestières constituent un capital naturel pour l’approvisionnement des populations locales, en bois, en plantes aromatiques et médicinales et en parcours pour le pâturage. Ces multiples usages ont conduit ces populations à mettre en place une gestion communautaire et très ancienne de ces ressources. Depuis 2002, l’administration des Eaux et Forêts a mis en place une politique forestière basée sur une stratégie de gestion participative. Nous avons étudié les formes de gestion communautaire et par l’administration des ressources forestières dans quatre communes rurales du Parc National d’Ifrane. L’administration organise une mise en défens, fondée sur l’implication et la responsabilisation des populations usagères, organisée en associations sylvo-pastorales ou en coopératives forestières, à travers une incitation financière sous forme de compensation. Ce mécanisme a permis d’obtenir un certain nombre d’acquis : conscientisation des populations vis-à-vis de la mise en défens, investissement des sommes de la compensation dans des projets de développement local, etc. Cependant, ce mécanisme présente certaines fragilités, notamment un risque de non durabilité des mises en défens (du fait que celles-ci ne sont financées que par le budget de l’Etat et un contrôle social plus faible dans les nouvelles associations qui n’ont pas la même légitimité pour prendre des décisions au nom du collectif que les anciennes jmaa.

    Full Text Available O Brasil está entre os 10 países que mais desperdiçam alimentos no mundo. Aproximadamente 35% da produção agrícola nacional tornam-se lixo, que representa quantitativamente valores acima de 10 milhões de toneladas de alimentos, e caso estes não sejam considerados a alguma finalidade, podem comprometer o meio ambiente.Mediante o grande desperdício de alimentos ocorridos na região do Cariri, dentre eles os de maior destaque são as frutas e hortaliças, com consequente geração de resíduos originários das etapas de produção, distribuição e comercialização. Ressalta-se a importância de conhecimentos acerca da adoção de práticas em respeito ao ambiente, portanto, o presente estudo teve como objetivo analisar o gerenciamento de resíduos provenientes de determinadas empresas do setor hortifrúti da região do Cariri. Diante dos resultados encontrados neste estudo observou-se que todas as empresas geram resíduos e que estão sendo capazes de utilizá-los atribuindo aos mesmos finalidades como alimentação animal e compostagem, o que nos garante que tais empresas, preconizam condutas de gerenciamento de resíduos adequadas, adotando uma postura ética de comprometimento com o social e o meio ambiente.Palavras-chave: desperdício, compostagem, meio ambiente.

    The accurate representation of aerosols in climate models requires direct ambient measurement of the size- and composition-dependent particle production fluxes. Here we present the design, testing, and analysis of data collected through the first instrument capable of measuring hygroscopicity-based, size-resolved particle fluxes using a continuous-flow Hygroscopicity-Resolved Relaxed Eddy Accumulation (Hy-Res REA) technique. The different components of the instrument were extensively tested inside the US Environmental Protection Agency's Aerosol Test Facility for sea-salt and ammoniums sulfate particle fluxes. The new REA system design does not require particle accumulation, therefore avoids the diffusional wall losses associated with long residence times of particles inside the air collectors of the traditional REA devices. The Hy-Res REA system used in this study includes a 3-D sonic anemometer, two fast-response solenoid valves, two Condensation Particle Counters (CPCs), a Scanning Mobility Particle Sizer (SMPS), and a Hygroscopicity Tandem Differential Mobility Analyzer (HTDMA). A linear relationship was found between the sea-salt particle fluxes measured by eddy covariance and REA techniques, with comparable theoretical (0.34) and measured (0.39) proportionality constants. The sea-salt particle detection limit of the Hy-Res REA flux system is estimated to be 6x105 m-2s-1. For the conditions of ammonium sulfate and sea-salt particles of comparable source strength and location, the continuous-flow Hy-Res REA instrument was able to achieve better than 90% accuracy of measuring the sea-salt particle fluxes. In principle, the instrument can be applied to measure fluxes of particles of variable size and distinct hygroscopic properties (i.e., mineral dust, black carbon, etc.).

  5. Relativization of the material “res judicata” in the brazilian civil suit Relativização da coisa julgada material no processo civil brasileiro

    Full Text Available It also addresses the debate about the revitalization of the res judicata in the civil suit of the individual cognitive tutelage when the sentence goes against constitutional norms or principles. It highlights that only the existent sentences, which lead to res judicata unconstitutional or unjust, may be relativized. It sees the principle of proportionality as a method or criterion adequate to solve the conflict of values that arises when the law enforcer is faced with an unfair or unconstitutional sentence. Only the consideration upon values, in a true case, is able to determine whether the res judicata must be kept or not in the juridical order. To relativize the res judicata unconstitutional a de-constitutive action is proposed, with the same characteristics of a rescinding action, but not subject to terms of duration.Trata da polêmica sobre a relativização da coisa julgada no processo civil de tutela cognitiva individual, quando a sentença afronta normas ou princípios constitucionais. Enfoca que somente as sentenças existentes, que produzem coisa julgada inconstitucional ou injusta, podem ser relativizadas. Aponta o princípio da proporcionalidade como método ou critério adequado para resolver o conflito de valores. Somente a ponderação de valores, no caso concreto, é capaz de determinar se a coisa julgada deve ser mantida ou não na ordem jurídica. Para relativizar a coisa julgada inconstitucional propõe o cabimento de uma ação desconstitutiva, com as mesmas características da ação rescisória, mas não sujeita a prazo.

  6. Experimental determination of the hydrothermal solubility of ReS2 and the Re–ReO2 buffer assemblage and transport of rhenium under supercritical conditions

    Full Text Available To understand the aqueous species important for transport of rhenium under supercritical conditions, we conducted a series of solubility experiments on the Re–ReO2 buffer assemblage and ReS2. In these experiments, pH was buffered by the K–feldspar–muscovite–quartz assemblage; in sulfur-free systems was buffered by the Re–ReO2 assemblage; and and in sulfur-containing systems were buffered by the magnetite–pyrite–pyrrhotite assemblage. Our experimental studies indicate that the species ReCl40 is dominant at 400°C in slightly acidic to near-neutral, and chloride-rich (total chloride concentrations ranging from 0.5 to 1.0 M environments, and ReCl3+ may predominate at 500°C in a solution with total chloride concentrations ranging from 0.5 to 1.5 M. The results also demonstrate that the solubility of ReS2 is about two orders of magnitude less than that of ReO2. This finding not only suggests that ReS2 (or a ReS2 component in molybdenite is the solubility-controlling phase in sulfur-containing, reducing environments but also implies that a mixing process involving an oxidized, rhenium-containing solution and a solution with reduced sulfur is one of the most effective mechanisms for deposition of rhenium. In analogy with Re, TcS2 may be the stable Tc-bearing phase in deep geological repositories of radioactive wastes.

    Many countries ravaged by conflict have substantial morbidity and mortality attributed to HIV/AIDS yet HIV treatment is uncommonly available. Universal access to HIV care cannot be achieved unless the needs of populations in conflict-affected areas are addressed. From 2003 Médecins Sans Frontières introduced HIV care, including antiretroviral therapy, into 24 programmes in conflict or post-conflict settings, mainly in sub-Saharan Africa. HIV care and treatment activities were usually integrated within other medical activities. Project data collected in the Fuchia software system were analysed and outcomes compared with ART-LINC data. Programme reports and other relevant documents and interviews with local and headquarters staff were used to develop lessons learned. In the 22 programmes where ART was initiated, more than 10,500 people were diagnosed with HIV and received medical care, and 4555 commenced antiretroviral therapy, including 348 children. Complete data were available for adults in 20 programmes (n = 4145). At analysis, 2645 (64%) remained on ART, 422 (10%) had died, 466 (11%) lost to follow-up, 417 (10%) transferred to another programme, and 195 (5%) had an unclear outcome. Median 12-month mortality and loss to follow-up were 9% and 11% respectively, and median 6-month CD4 gain was 129 cells/mm 3.Patient outcomes on treatment were comparable to those in stable resource-limited settings, and individuals and communities obtained significant benefits from access to HIV treatment. Programme disruption through instability was uncommon with only one program experiencing interruption to services, and programs were adapted to allow for disruption and population movements. Integration of HIV activities strengthened other health activities contributing to health benefits for all victims of conflict and increasing the potential sustainability for implemented activities. With commitment, simplified treatment and monitoring, and adaptations for potential

  11. Surgeons without borders: a brief history of surgery at Médecins Sans Frontières.

    Médecins Sans Frontières (MSF) is a humanitarian organization that performs emergency and elective surgical services in both conflict and non-conflict settings in over 70 countries. In 2006 MSF surgeons departed on approximately 125 missions, and over 64,000 surgical interventions were carried out in some 20 countries worldwide. Historically, the majority of MSF surgical projects began in response to conflicts or natural disasters. During an emergency response, MSF has resources to set up major operating facilities within 48 h in remote areas. One of MSF strengths is its supply chain. Large pre-packaged surgical kits, veritable "operating theatres to go," can be readied in enormous crates and quickly loaded onto planes. In more stable contexts, MSF has also strengthened the delivery of surgical services within a country's public health system. The MSF surgeon is the generalist in the broadest sense and performs vascular, obstetrical, orthopaedic, and other specialized surgical procedures. The organization aims to provide surgical services only temporarily. When there is a decrease in acute needs a program will be closed, or more importantly, turned over to the Ministry of Health or another non-governmental organization. The long-term solution to alleviating the global burden of surgical disease lies in building up a domestic surgical workforce capable of responding to the major causes of surgery-related morbidity and mortality. However, given that even countries with the resources of the United States suffer from an insufficiency of surgeons, the need for international emergency organizations to provide surgical assistance during acute emergencies will remain for the foreseeable future.
