Monoamine oxidase activity was quantitatively assessed by cytochemical method in brain structures (layers III and V of the sensorimotor cortex, caudate nucleus, nucleus accumbens, hippocampal CA3 field) of rats of August line and Wistar population with high and low locomotor activity in the open fi eld test. Monoamine oxidase activity (substrate tryptamine) predominated in the nucleus accumbens of Wistar rats with high motor activity in comparison with rats with low locomotor activity. In August rats, enzyme activity (substrates tryptamine and serotonin) predominated in the hippocampus of animals with high motor activity. Comparison of August rats with low locomotor activity and Wistar rats with high motor activity (i.e. animals demonstrating maximum differences in motor function) revealed significantly higher activity of the enzyme (substrates tryptamine and serotonin) in the hippocampus of Wistar rats. The study demonstrates clear-cut morphochemical specificity of monoaminergic metabolism based on the differences in the cytochemical parameter "monoamine oxidase activity", in the studied brain structures, responsible for the formation and realization of goal-directed behavior in Wistar and August rats.

Author's modification of azomethod and benzidine method were used for determination of the enzyme activity of alkaline phosphatase and peroxidase, respectively, in 62 healthy medical workers. Leucocyte alkaline phosphatase showed a high cytochemical index - 181+-23. Peroxidase was also increased - 234+-9,8. There were no statistically significant differences between the values in physicians, nurses and hospital attendants. The same was true when referred to the duration of service. These studies demonstrate the influence of ionizing radiation on the biochemical characteristics of leucocytes at a time when there were no distinct clinical symptoms and complex morphological changes in the peripheral blood.

The development of the suspensor in two species - Sempervivum arachnoideum and Jovibarba sobolifera - was investigated using cytochemical methods, light and electron microscopy. Cytological processes of differentiation in the embryo-suspensor were compared with the development of embryo-proper. The mature differentiated suspensor consists of a large basal cell and three to four chalazal cells. The basal cell produces haustorial branched invading ovular tissues. The walls of the haustorium and the micropylar part of the basal cell form the wall ingrowths typical for a transfer cells. The ingrowths also partially cover the lateral wall and the chalazal wall separating the basal cell from the other embryo cells. The dense cytoplasm filling the basal cell is rich in: numerous polysomes lying free or covering rough endoplasmic reticulum (RER), active dictyosomes, microtubules, bundles of microfilaments, microbodies, mitochondria, plastids and lipid droplets. Cytochemical tests (including proteins, insoluble polysaccharides and lipids are distributed in the suspensor during different stages of embryo development) showed the presence of high amounts of macromolecules in the suspensor cells, particularly during the globular and heart-shaped phases of embryo development. The protein bodies and lipid droplets are the main storage products in the cells of the embryo-proper. The results of Auramine 0 indicate that a cuticular material is present only on the surface walls of the embryo-proper, but is absent from the suspensor cell wall. The ultrastructural features and cytochemical tests indicate that in the two species - S. arachnoideum and J. sobolifera - the embryo-suspensor is mainly involved in the absorption and transport of metabolites from the ovular tissues to the developing embryo-proper.

Recently a highly sensitive cytochemical bioassay (CBA) for the determination of human TSH has been developed. We could show that this assay is specific for TSH and measurements done on plasma of normal euthyroid persons agree well with radioimmunological findings. Due to the extreme sensitivity of the CBA we were able to detect low but measurable TSH levels in patients with primary hyperthyroidism, which were not increased by TRH treatment before therapeutic treatment. After therapeutic treatment, TRH application was able to stimulate additional biologically active TSH release which, however, barely reached the lowest limit of detection by RIA. In certain pathological cases we were able to detect elevated plasma TSH levels, which were active immunologically but inactive biologically. (orig.) [de

To determine blood cell morphologic characteristics and hematologic and plasma biochemical reference ranges for iguanas housed in a warm indoor and outdoor environment with regular exposure to direct sunlight. Original study. 51 clinically normal iguanas (18 males, 25 females, and 8 juveniles) housed in 3 Florida locations. Blood was collected from the coccygeal or ventral abdominal vein. Any samples that had obvious hemolysis or clot formation were not used. Leukocyte counts were determined manually; other hematologic values were obtained by use of a commercially available cell counter. Plasma biochemical values were determined by use of a spectrophotometric chemistry analyzer. Blood smears were stained with Wright-Giemsa and cytochemical stains for morphologic and cytochemical evaluation. Hematologic ranges were generally higher in this study than previously reported. Thrombocytes were variable in appearance between individuals and sometimes difficult to distinguish from lymphocytes on a Wright-Giemsa preparation. Concentrations of calcium, phosphorus, total protein, globulins, and cholesterol were significantly higher, and the albumin:globulin ratio was significantly lower, in healthy gravid females than in male or nongravid female iguanas. Nongravid females had significantly higher calcium and cholesterol concentrations, compared with males. The calcium:phosphorus ratio was > 1 in all iguanas. Gravid females had a calcium phosphorus product ranging between 210 and 800. Intracytoplasmic inclusions were identified within the erythrocytes of some iguanas. Hematologic ranges for iguanas in this study are higher than those reported for iguanas. Sex and age of the iguana should be considered when evaluating biochemical values. Healthy ovulating and gravid females may have significantly increased electrolyte and protein concentrations, but maintain a calcium:phosphorus ratio > 1.

Ultrastructural cytochemical studies revealed peroxidase activity in five of 25 adult patients with apparent null lymphoblastic leukemia (ALL) in whom the peroxidase reaction studied with light microscopy was negative. None of these 5 patients responded to a chemotherapy regimen used for adult ALL. The importance of ultrastructural cytochemistry which allows the recognition of myeloblastic differentiation in undifferentiated blast cells is also demonstrated. The correct classification of such cases may be important for prognosis because they appear to be resistant to the chemotherapy used in treating ALL.

With a new method, sequential immunological, cytochemical and cytokinetic studies were done on lymphoid cells in the peripheral blood of 12 healthy adults. Every single lymphoid cell could therefore be characterized by the following markers: surface immunoglobulins (sIg); rosetting with sheep red blood cells (E); unspecific acid alpha-naphthyl acetate esterase (ANAE); and 3HdT incorporation. Significantly more E+sIg-ANAE-cells (51% and 22% of all lymphoid cells, respectively). Of all ANAE+ cells 90% were E+, but 64% of all ANAE- cells were also E+. In all individuals a subpopulation of E+sIg+ cells was found. The esterase pattern of these cells was similar to that of E-sIg+ cells. The overall labeling index of the lymphoid cells examined was less than or equal to 0.2%

By using the technology of microscopy,electron microscopy and enzyme cytochemical localization, comparison was made of the cytomorphology, ATPase and cytochrome oxidase activity in pollens during microspore formation and pollen development, for K-type cytoplasmic male sterile (CMS) lines, T-type CMS lines and their maintainer lines on wheat. The results indicated that pollen abortion of the T-type CMS lines mainly occurred at the later mononucleate pollen stage, and cytomorphological changes of the abortive pollen began with a vacuolar membrane, and pollen aborting was related to a lack of ATPase activity in the nucleus and nucleolus during the mononucleate pollen stage. Pollen abortion of the K-type CMS lines took place mainly during the later binucleate and trinucleate stages, and cytomorphological changes of the abortion first began with mitochondria. The abortion was related to intine disruption.

Azini was isolated from the glandula lacrimalis of the rat. Its vitality was proven by oxygen use measurements. In autoradiographic studies isolated Azini was marked with L-(4,5- 3 H)-leucine and fixed at various times thereafter. The light microscopic autoradiography showed a time dependent distribution of the silver grains whose association with membrane-enclosed compartments made the electron microscopic autoradiography possible. This distribution allows an analysis of the kinetics of the intracellular transport of secreted proteins. Because of its limited spatial resolution the autoradiographic research methods were combined with the cytochemical presentation of the peroxidase, a secreted protein, of the lacrimal duct.

An investigation into the differential susceptibility of liver cellular membranes to peroxidative processes has been performed, using x irradiation on the liver surface, resulting in a a 3-mm penetrating gradient of membrane damage. Ultrastructural, cytochemical, and histochemical findings in this area point to a differential sensitivity of cellular membranes to x irradiation. The plasma membrane and the lysosomal membrane, containing much lipid and cholesterol and little membrane and the lysosomal membrane, containing much lipid and cholesterol and little vitamin E, are highly susceptible to x irradiation. Less sensitive are the membranes of mitochondria and endoplasmic reticulum, containing relatively much vitamin E and proteins and a lower amount of lipids and cholesterol

Peroxisomes in the nervous system of Aplysia californica: a cytochemical study.

We have studied the distribution of peroxisomes in the abdominal ganglion of Aplysia californica using electron microscopic cytochemical methods. Reaction product for catalase was observed in small ovoid or dumb-bell-shaped bodies in the perikarya of many of the neurons. The abundance of these catalase-reactive peroxisomes is considerably greater than is the case in vertebrate neurons. While the non-neuronal cells of the Aplysia abdominal ganglion do contain appreciable peroxisome populations, there were few peroxisomes in glial cytoplasm directly adjacent to the perikarya, again contrasting with vertebrate ganglia in which the satellite cells are a principal site of peroxisomes. Peroxisomes are present throughout the perikaryal cytoplasm. In the regions in which lipochrome granules abound, peroxisomes are frequently seen closely associated with these granules; glycogen is abundant nearby. The association of peroxisomes, lipochrome granules and glycogen is interesting in view of the propinquities of peroxisomes to lipid droplets and lipofuscin granules reported for non-neuronal vertebrate tissues, and in view of the growing evidence indicating that some of the roles of peroxisomes are in lipid metabolism and in gluconeogenesis. Some of the lipochrome granules themselves show reaction product in ganglia incubated to demonstrate catalase activity and some react in tissue incubated to demonstrate acid phosphatase activity. Such observations suggest that the enzymatic capacities of the lipochrome granules merit further studies, and that the granules may be of complex or heterogeneous nature.

We aimed to verify whether hydrogen peroxide (H 2 O 2 ) accumulation and cell death are detected early in three bioindicators of ozone (O 3 ), Nicotiana tabacum 'Bel-W3', Ipomoea nil 'Scarlet O'Hara' and Psidium guajava 'Paluma', and whether environmental factors also affect those microscopic markers. The three species were exposed to chronic levels of O 3 in a subtropical area and a histo-cytochemical technique that combines 3,3'-diaminobenzidine (DAB) with Evans blue staining was used in the assessments. The three species accumulated H 2 O 2 , but a positive correlation with O 3 concentration was only observed in N. tabacum. A positive correlation between O 3 and cellular death was also observed in N. tabacum. In I. nil and P. guajava, environmental factors were responsible for symptoms at the microscopic level, especially in P. guajava. We conclude that the most appropriate and least appropriate bioindicator plant for O 3 monitoring in the subtropics are N. tabacum 'Bel-W3' and P. guajava 'Paluma', respectively. - Highlights: → H 2 O 2 and cell death occur in response to O 3 and other stressful factors. → H 2 O 2 can be detected by DAB and cell death by Evans blue staining. → These techniques contribute for analysis of susceptible bioindicator species. → H 2 O 2 and cell death were explained by high levels of O 3 in N. tabacum 'Bel-W3'. → N. tabacum is the most appropriate plant for monitoring in subtropics. - Nicotiana tabacum 'Bel-W3' is better than native species for O 3 biomonitoring in the subtropics, as revealed by histo-cytochemical techniques.

Full Text Available OBJECTIVES: With normal hysterosalpingography (HSG results, selecting suitable candidates for the laparoscopic treatment of probable pelvic adhesions following previous pelvic inflammatory disease, it would be wise to investigate serum antibody screening against chlamidia trachomatis. It is worth to evaluate whether it is useful to detect a negative antichlamidial antibody disease for cancelling laparoscopy for a while with abnormal HSG findings. These two subjects have been investigated in study. MATERIAL AND METHODS: For detecting diagnostic value of serum antichlamidial antibody, in our infertility clinic, postoperative blood samples of 80 patients who were hospitalized for diagnostic laparoscopy to investigate infertility ethiology between May 2004 and November 2005 have been tested with microelisa method for antichlamidial IgM and IgG antibodies. HSG films of the patients performed at least one year were evaluated. Venous blood was drawn from these patients during postoperative early period for studying serum IgM and IgG antibodies of chlamidia trachomatis and the results were compared with operative findings. RESULTS: According to the antichlamidial antibody levels 60 (75% patients have not been infected with chlamidia and 20 (25% patients have been infected previously. When the patients were divided to two groups; normal and abnormal; based on preoperative HSG films; 18 (30% of the 60 patients with abnormal HSG films and 2 (10% of the 20 patients with normal HSG films had positive antichlamidial antibody levels respectively. CONCLUSION: The relationship between chlamidia trachomatis infection and tubal infertility has been demonstrated among 85% of patients with positive antichlamidial antibody levels and 46.7% of patients with negative levels who had tubal passage defects detected during diagnostic laparoscopy.

1991-01-01

The initiation of oocyte and follicle growth was studied in 1- and 3-d-old calf ovaries using cytochemical, autoradiographical and electron microscopical approaches. Attention was only paid to unilaminar ovarian follicles that were classified into 3 categories: unilaminar flattened (UF), unilaminar flatto-cuboidal (UFC) and unilaminar cuboidal (UC) ovarian follicles when the oocyte was surrounded by 1 layer of flattened, a mixture of flattened and cuboidal and entirely cuboidal follicle cells, respectively. Our findings suggested that oocytes within each of these follicle categories were in different developmental stages. Furthermore, electron microscopic observations revealed that early after birth, oocyte nuclei characteristic of diplotene configuration (aggregation of the nuclear chromatin into moderately electron-dense small patches and fibrillo-granular texture of the nucleolus) were encountered in 41% of the UF follicles. The rest of the UF as well as all of the UFC and UC follicles were found to contain dictyate oocytes in which the chromatin was highly decondensed and the nucleolus differentiated into fibrillar, fibrillo-granular and granular components. The present results also indicated that the complete transition of the surrounding follicle cells from flattened to cuboidal shape and the morphological changes of the oocyte endoplasmic reticulum and mitochondria were 2 complementary events essential for initiation of oocyte growth

Peroxidase activity in root hairs of cress (lepidium sativum L.) Cytochemical localization and radioactive labelling of wall bound peroxidase

International Nuclear Information System (INIS)

Zaar, K.

1979-01-01

The ultrastructural localization of peroxidase activity in young, growing root hairs of cress (Lepidium sativum L.) after assay with 3,3'-diaminobenzidine is reported. Prominent peroxidase activity has been found in the dictyosomes and the associated vesicles, in ribosomes on ER-cisternae, as well as in the cell wall. On the basis of both ultrastructural and cytochemical evidence it is proposed that peroxidase in root hairs is synthesized on the ER- and within dictyosome cisternae packaged and transported in secretory vesicles and extruded into the cell wall particularily at the tip region of a root hair. The kinetic of Golgi apparatus mediated peroxidasesecretion was monitored by measuring the 55 Fe protoheme content of primary cell walls. Peroxidase secretion seems to be enhanced during stress incubation in destilled water. Secretory activity in root hairs is 20 times higher than in cells of the root body. (author)

Full Text Available Mycelium isolated from fruitbodies of Rhizopogon roseolus, collected from calamine wastes in Poland, was cultivated on agar media supplemented with Zn or Pb salts. The stimulation of exudate production by the aerial mycelium and the mycelium growing on the surface of the media, accompanied by the change of mycelium pigmentation, was found as a result of Zn application. The presence of Pb resulted mainly in the stimulation of crystalloid production on the surface of mycelium, in direct contact with the medium. Exudate droplets formed on the surface of mycelium cultivated on media with and without the Zn addition, were investigated by means of cytochemical tests (PATAg and Gomori-Swift reaction. In the control media most droplets gave a diffused, positive reaction to both tests. In media supplemented with Zn salts, besides the droplet-like material described in the control also another kind of exudate was observed. It was characterized by the collar showing apositive Gomori-Swift reaction, while the rest of the exudate had an oily appearance and gave a faint or no reaction to both tests. Comparative research by means of scanning electron microscopy accompanied by energy dispersion spectroscopy, was carried out showing the differences in exudate and in mycelia composition as a result of the Zn and Pb presence in the medium.

Immuno and affinity cytochemical analysis of cell wall composition in the moss Physcomitrella patens

Full Text Available In contrast to homeohydric vascular plants, mosses employ a poikilohydric strategy for surviving in the dry aerial environment. A detailed understanding of the structure, composition, and development of moss cell walls can contribute to our understanding of not only the evolution of overall cell wall complexity, but also the differences that have evolved in response to selection for different survival strategies. The model moss species Physcomitrella patens has a predominantly haploid lifecycle consisting of protonemal filaments that regenerate from protoplasts and enlarge by tip growth, and leafy gametophores composed of cells that enlarge by diffuse growth and differentiate into several different types. Advantages for genetic studies include methods for efficient targeted gene modification and extensive genomic resources. Immuno and affinity cytochemical labeling were used to examine the distribution of polysaccharides and proteins in regenerated protoplasts, protonemal filaments, rhizoids, and sectioned gametophores of P. patens. The cell wall composition of regenerated protoplasts was also characterized by flow cytometry. Crystalline cellulose was abundant in the cell walls of regenerating protoplasts and protonemal cells that developed on media of high osmolarity, whereas homogalacturonan was detected in the walls of protonemal cells that developed on low osmolarity media and not in regenerating protoplasts. Mannan was the major hemicellulose detected in all tissues tested. Arabinogalactan proteins were detected in different cell types by different probes, consistent with structural heterogeneity. The results reveal developmental and cell type specific differences in cell wall composition and provide a basis for analyzing cell wall phenotypes in knockout mutants.

CYTOCHEMICAL STUDIES OF THE NUCLEOPROTEINS OF HELA CELLS INFECTED WITH HERPES VIRUS.

Science.gov (United States)

Love, R; Wildy, P

1963-05-01

The morphological and cytochemical changes in HeLa cells infected with herpes virus have been studied at frequent intervals during infection and related to the growth of virus and the multiplicity of the virus inoculum. Infection with a high multiplicity inoculum produced enlargement and extrusion of small ribonucleoprotein (RNP) bodies in the nucleoli (nucleolini) to form RNP bodies in the nucleoplasm (B bodies) beginning (1/2) hour after infection. 3 hours after infection, RNP of the pars amorpha appeared to diffuse into the adjacent nucleoplasm, where, (1/2) hour later, the classical type A inclusion or A body first appeared. The A bodies displaced the B bodies and the nucleoli and eventually filled the nucleus. 6 hours after infection, minute granules containing RNA, DNA, and non-histone protein appeared inside the A bodies (A granules) and increased in number until the late stages of infection, when they disappeared. 18 hours after infection, at the time when the A bodies came to fill the nucleus completely, extrusion of RNP from the nucleus produced cytoplasmic masses which have been termed C bodies. B bodies were formed in the majority of cells before the maturation of infectious virus, but the number of B bodies could not be correlated with the amount of virus in the cell or with the multiplicity of the inoculum. It is suggested that the formation of B bodies may be the result of inhibition of the onset of mitotic division by a mechanism which does not inhibit the formation of RNA in the nucleolini. The nature of the A bodies, the A granules, and the C bodies is discussed and it is concluded that the A granules may represent aggregations of maturing virus in the nucleus. The progression of some C mitotic metaphases to the formation of post-C mitotic multinucleated giant cells is described. These are distinct from syncytia formed by cell fusion.

Full Text Available For the first time, a morphological study of haemocytes from the crab Carcinus aestuarii was carried out by means of light microscopy and differing cytochemical assays. Analysis of haemocyte size frequency distribution (performed by means of a Coulter Counter revealed the presence of two distinct haemocyte fractions in C. aestuarii haemolymph, depending on cell size. The first fraction was of about 3-5 µm in diameter and 30-50 fL in volume, the second was of about 6-12 µm in diameter and over 200 fL in volume. Mean cell diameter and volume were 8.20±1.7 µm and 272.30±143.5 fL, respectively. Haemocytes observed under light microscope were distinguished in three cell types: granulocytes (28%; 11.94±1.43 µm in diameter with evident cytoplasmic granules, semigranulocytes (27%; 12.38±1.76 µm in diameter with less granules than granulocytes, and hyalinocytes (44%; 7.88±1.6 µm in diameter without granules. In addition, a peculiar cell type was occasionally found (about 1%: it was 25-30 µm in diameter and had a great vacuole and a peripheral cytoplasm with granules. Granulocyte and semigranulocyte granules stained in vivo with Neutral Red, indicating that they were lysosomes. Giemsa’s dye confirmed that granulocytes and semigranulocytes were larger than hyalinocytes. Pappenheim’s panoptical staining and Ehrlich’s triacid mixture allowed to distinguish granule-containing cells (including semigranulocytes in acidophils (64%, basophils (35% and neutrophils (1%. Hyalinocytes showed always a basophilic cytoplasm. Haemocytes were positive to the PAS reaction for carbohydrates, even if cytoplasm carbohydrate distribution varied among cell types. Lastly, lipids were found on cell membrane and in cytoplasm of all haemocyte types in the form of black spots produced after Sudan Black B staining. The morphological characterisation of C. aestuarii haemocytes by light microscopy was necessary before performing both ultrastructural and functional

Differential sensitivity of cellular membranes to peroxidative processes. An electronmicroscopic, histochemical and cytochemical study of the effects of vitamin E deficiency and X-irradiation on the liver of the Pekin duckling

A description is given of a morphological and cytochemical investigation into the effects of both vitamin E deficiency and x irradiation on the ultrastructure and enzyme activities of several cellular membranes, particularly the plasma membrane and the membranes of lysosomes, mitochondria and endoplasmic reticulum. In the vitamin E deficient situation, the radicals and peroxides only originate near mitochondria and endoplasmic reticulum, so that these membrane systems suffer from changes. After irradiation of the liver of both the control duckling and the deficient duckling, radicals originate in all parts of the cell. Due to their high content of lipids and cholesterols, peroxides will occur mainly in plasma membranes and lysosomal membranes. Moreover, in these membranes there is hardly any protection by vitamin E.

A cytochemical and immunocytochemical analysis of the wall labyrinth apparatus in leaf transfer cells in Elodea canadensis.

Science.gov (United States)

Ligrone, Roberto; Vaughn, Kevin C; Rascio, Nicoletta

2011-04-01

Transfer cells are plant cells specialized in apoplast/symplast transport and characterized by a distinctive wall labyrinth apparatus. The molecular architecture and biochemistry of the labyrinth apparatus are poorly known. The leaf lamina in the aquatic angiosperm Elodea canadensis consists of only two cell layers, with the abaxial cells developing as transfer cells. The present study investigated biochemical properties of wall ingrowths and associated plasmalemma in these cells. Leaves of Elodea were examined by light and electron microscopy and ATPase activity was localized cytochemically. Immunogold electron microscopy was employed to localize carbohydrate epitopes associated with major cell wall polysaccharides and glycoproteins. The plasmalemma associated with the wall labyrinth is strongly enriched in light-dependent ATPase activity. The wall ingrowths and an underlying wall layer share an LM11 epitope probably associated with glucuronoarabinoxylan and a CCRC-M7 epitope typically associated with rhamnogalacturonan I. No labelling was observed with LM10, an antibody that recognizes low-substituted and unsubstituted xylan, a polysaccharide consistently associated with secondary cell walls. The JIM5 and JIM7 epitopes, associated with homogalacturonan with different degrees of methylation, appear to be absent in the wall labyrinth but present in the rest of cell walls. The wall labyrinth apparatus of leaf transfer cells in Elodea is a specialized structure with distinctive biochemical properties. The high level of light-dependent ATPase activity in the plasmalemma lining the wall labyrinth is consistent with a formerly suggested role of leaf transfer cells in enhancing inorganic carbon inflow. The wall labyrinth is a part of the primary cell wall. The discovery that the wall ingrowths in Elodea have an antibody-binding pattern divergent, in part, from that of the rest of cell wall suggests that their carbohydrate composition is modulated in relation to transfer

The volume of pollen, total number of pollen/flower, the percent of pollen germination and tube growth of long-styled flower were higher than the short-styled flowers in S. torvum. In addition, the pollination studies were conducted among the four selected sets for optimum fruit set investigation. Fruit set was not seen in both the first and second sets (female shorts-short male and female short-long male). However, the maximum fruit set was obtained in the fourth set (female long-male long). Pollen grains of long-styled flowers irradiated with 1-800 krad were germinated in the basal medium. The percent of pollen germination and the tube growth was stimulated over the control with 1 and 50 krad dose exposures, but increasing dose rates inhibited both the above processes. Utilization of insoluble polysaccharides, and the synthesis of RNA and protein were enhanced over the control with the effect of 50 krad. The higher (800 krad) dose exposures inhibited all the above cytochemical constituents. Various dose-treated pollens were used to pollinate the stigma surface of the long-styled flowers. The fruit set, fruit volume, fresh and dry weight of fruits, and the number of seed set/fruit, were enhanced over the control by 1 and 50 krad, while the higher doses caused inhibitory effect. Interestingly, the fruit set was not caused by radiation doses 400 krad and above. (author)

Full Text Available The events involved in the maturation process of acinar secretory granules of rat parotid gland were investigated ultrastructurally and cytochemically by using a battery of four lectins [Triticum vulgaris agglutinin (WGA, Ulex europaeus agglutinin I (UEA-I, Glycine max agglutinin (SBA, Arachys hypogaea agglutinin (PNA]. In order to facilitate the study, parotid glands were chronically stimulated with isoproterenol to induce secretion. Specimens were embedded in the Lowicryl K4M resin. The trans-Golgi network (TGN derived secretory granules, which we refer to as immature secretory granules, were found to be intermediate structures in the biogenesis process of the secretory granules in the rat parotid acinar cell. These early structures do not seem to be the immediate precursor of the mature secretory granules: in fact, a subsequent interaction process between these early immature granule forms and TGN elements seems to occur, leading, finally, to the mature granules. These findings could explain the origin of the polymorphic subpopulations of the secretory granules in the normal acinar cells of the rat parotid gland. The lectin staining patterns were characteristic of each lectin. Immature and mature secretory gran- ules were labelled with WGA, SBA, PNA, and lightly with UEA-I. Cis and intermediate cisternae of the Golgi apparatus were labelled with WGA, and trans cisternae with WGA and SBA.

1989-01-01

Cervico vaginal smears of women with uterine carcinoma treated with radiotherapy are analyzed in the present work. A series of such smears showed morphological changes suggestive of Chlamydia infection with the Papanicolaou stain. Confirmation of the presence of such agent was done using an avidin-biotin peroxidase technique. A higher prevalence of Chlamydia in the group of patients with carcinoma of the uterus treated with irradiation than in the population without ionizing treatment was verified. The presence of cells with radiotherapic changes infected by Chlamydia is a new finding in cytology. (author)

The paper reported the verified case of neuroboreliosis with unusual clinical presentation of Parkinsonism. Study aimed at establishing the significance of a precise differential diagnosis with substantial analysis of the symptoms of several diseases to avoid the false diagnosis and to conduct the opportune and adequate therapeutic management. We described the case of the diagnosed neuroboreliosis with clinical expression of Multiple Sclerosis (MS) and Parkinsonism. A 44 years old man was diagnosed as MS according to the McDonald's Criteria, who within two years developed typical clinical signs of Parkinsonism. Patient investigated neurologically, Brain contrast MRI (1.5 Tesla) was performed; Cerebrospinal fluid was researched for oligoclonal bands. Blood IgM and IgG were researched against Chlamidia pneumonie, Micoplasma pneumonie, Borrelia Burgdorferi, Herpes simplex 1/2, Cytomegalovirus by ELISA method. Clinically the patient expressed amimic face, oligobradikinesia, extrapiramidal rigidity in all limbs, resting tremor in upper limb fingers, horizontal nystagmus. Brain MRI showed multiple gadolinium enhanced demyelization lesions in periventricular and sub-cortical white matter. CSF oligoclonal bands were positive without dysfunction of blood-brain barrier. Blood IgM, IgG detected to be negative against Chlamidia pneumonie, Micoplasma pneumonie, cytomegalovirus, Herpes simplex ½, while the blood IgG was strongly positive against Borrelia burgdorferi, confirmed by followed Western blot test. Patient was stabilized by puls-therapy with 1 gr/intravenous Solumedrol (5 days) along with Rocephin treatment (2 gr /iv) for 21 days followed by long term treatment with Antiparkin (Carbidopa 250 mg, Levodopa 25 mg). MS and even Parkinsonism in suspicious cases should thoroughly be investigated for differentiation from chronic Neuroboreliosis.

Asthma is a chronic inflammatory airway disease characterized by variable airway obstruction and bronchial hyperresponsiveness. There are many factors affecting the development and severity of childhood asthma such as genetic predisposition, atopy, environmental factors, obesity, diet, socioeconomic status, and infectious triggers. In the present study we aimed to investigate the frequency of Mycdoplasma pneumoniae, Chlamydia pneumoniae, and Helicobacter pylori infections in asthmatic children. We investigated also whether there is a relationship between these agents and asthma attacks. Seventy-nine asthmatic children (46 males, aged 5-15 years) were included in study. The study group was divided into two groups: group 1 consisted of 37 children with asthma attacks and group 2 consisted of 42 children with stable asthma. As a control group we studied 36 healthy children. Pulmonary function tests, skin prick tests for common allergens were performed; serum total IgE, phadiatop, specific IgM and IgG antibody levels (ELISA) for M. pneumoniae, C. pneumoniae and H. pylori were measured in all patients. Mycoplasma IgM and Chlamidia IgM were positive in 8.1% (3 patients) and 18.9% (7 patients) of group 1 patients, respectively. There was a statistically significant difference for Mycoplasma IgM (p = 0.031) and Chlamidia IgM (p = 0.03) between group1 and other two groups. We have not found significant difference for M. pneumoniae IgG, C. pneumoniae IgG and H. pylori IgM and IgG among groups. M. Pneumoniae and C. Pneumoniae may play a role in development of asthma exacerbations in childhood. We could not find a relationship between H. Pylori and asthma.

Full Text Available Although various tissue macrophages possess high glucose- 6-phosphate dehydrogenase (G6PD activity, which is reported to be closely associated with their phagocytotic/bactericidal function, the fine subcellular localization of this enzyme in liver resident macrophages (Kupffer cells has not been determined.We have investigated the subcellular localization of G6PD in Kupffer cells in rat liver, using a newly developed enzyme-cytochemical (copper-ferrocyanide method. Electron-dense precipitates indicating G6PD activity were clearly visible in the cytoplasm and on the cytosolic side of the endoplasmic reticulum of Kupffer cells. Cytochemical controls ensured specific detection of the enzymatic activity. Rat Kupffer cells abundantly possessed enzyme-cytochemically detectable G6PD activity. Kupffer cell G6PD may play a role in liver defense by delivering NADPH to NADPH-dependent enzymes. G6PD enzyme-cytochemistry may be a useful tool for the study of Kupffer cell functions.

The purpose of our study was to determine the effect of dilution and liquid-preservation of boar sperm on oxidoreductive capability of their mitochondria. The semen was diluted with BTS extender produced from water purified by destillation or by reverse osmosis. The spermatozoa were stored over a four-day period at 16-18 degrees C. The function of sperm mitochondria was assessed using the screening cytochemical test for NADH-dependent oxidoreductases (diaphorase/NADH, related to flavoprotein). Morphological assessment of cytochemical reaction was carried out using a light microscope. The intensity of the reaction was evaluated by means of a computer image analysing system (Quantimet 600S), measuring the integrated optical density (IOD) and mean optical density (MOD) of the reaction product (formazans) occurring in the sperm midpieces. In the non-diluted semen, intensive cytochemical reaction throughout the length of the sperm midpiece was observed. Furthermore, spermatozoa with the intensive reaction displayed the high optical density values. After dilution the semen with two variants of experimental extender, and as the conservation time expired, the cytochemical reaction was less intensive. Moreover, the absence of formazan deposits in various parts of the sperm midpiece was also noted. These morphological features corresponded to low values of optical density. These findings suggest that the dilution of semen and the time of sperm preservation may be critical factors that handicap energy metabolism of sperm mitochondria. The type of water used in preparing BTS extender does not have any significant effect on the oxidoreductive capability of sperm boar mitochondria.

Triple-aspect monism: physiological, mental unconscious and conscious aspects of brain activity.

Science.gov (United States)

Pereira, Alfredo

2014-06-01

Brain activity contains three fundamental aspects: (a) The physiological aspect, covering all kinds of processes that involve matter and/or energy; (b) the mental unconscious aspect, consisting of dynamical patterns (i.e., frequency, amplitude and phase-modulated waves) embodied in neural activity. These patterns are variously operated (transmitted, stored, combined, matched, amplified, erased, etc), forming cognitive and emotional unconscious processes and (c) the mental conscious aspect, consisting of feelings experienced in the first-person perspective and cognitive functions grounded in feelings, as memory formation, selection of the focus of attention, voluntary behavior, aesthetical appraisal and ethical judgment. Triple-aspect monism (TAM) is a philosophical theory that provides a model of the relation of the three aspects. Spatially distributed neuronal dendritic potentials generate amplitude-modulated waveforms transmitted to the extracellular medium and adjacent astrocytes, prompting the formation of large waves in the astrocyte network, which are claimed to both integrate distributed information and instantiate feelings. According to the valence of the feeling, the large wave feeds back on neuronal synapses, modulating (reinforcing or depressing) cognitive and behavioral functions.

The aspect system of the Chandra Observatory plays a key role in realizing the full potential of Chandra's x-ray optics and detectors. To achieve the highest spatial and spectral resolution (for grating observations), an accurate post-facto time history of the spacecraft attitude and internal alignment is needed. The CXC has developed a suite of tools which process sensor data from the aspect camera assembly and gyroscopes, and produce the spacecraft aspect solution. In this poster, the design of the aspect pipeline software is briefly described, followed by details of aspect system performance during the first eight months of flight. The two key metrics of aspect performance are: image reconstruction accuracy, which measures the x-ray image blurring introduced by aspect; and celestial location, which is the accuracy of detected source positions in absolute sky coordinates.

The vascularization of 50 tumors of the central nervous system (CNS) including 17 meningiomas, 25 neuroectodermal tumors, i.e., astrocytomas, oligodendrogliomas, mixed gliomas, glioblastomas, medulloblastomas, seven metastatic carcinomas, and one malignant hemangioendothelioma were investigated using biotinylated Ulex europaeus type I lectin (UEA I) in an indirect avidinbiotin-peroxidase procedure. The cytochemical staining pattern of UEA I on paraffin sections was compared with that of biotinylated Dolichos biflorus lectin (DBA), and with the immunocytochemical staining of factor VIII related antigen (F VIII/RAG) by polyclonal antisera using the PAP technique. UEA I visualized the endothelia of blood vessels with equal intensity, sensitivity, and reliability in normal brain and in tumor tissue with neovascularization. While large, medium, and small vessels were equally well demonstrated by UEA I and antibodies against FVIII/RAG, capillaries and endothelial sprouts were stained more consistently and intensely by UEA I. No reliable cytochemical staining could be obtained by DBA regardless of tissue or cell type investigated. It is concluded that UEA I is a highly useful cytochemical marker for the identification of vascular endothelia in paraffin sections of human brain tumors.

The effect of x rays (1300 R) and gamma irradiation (3000 R) on phagocytic activity of mouse peritoneal macrophages cultivated in vitro was studied using human glutaraldehyde-fixed red blood cells. The peroxidative activity of haemoglobin was cytochemically detected by the DAB method. The obtained results indicate that the applied dose of x irradiation does not affect the phagocytic activity of macrophages. On the contrary, the gamma irradiation (3000 R) causes acceleration of phagocytic activity of macrophages with concomitant impairment of intracellular digestion of ingested material. Weakened cytochemical reaction for acid phosphatase suggests that sufficiently high doses of irradiation cause some disturbances in the biosynthesis of lysosomal enzymes in exposed macrophages.

The Large Aspect Ratio Tokamak Study (LARTS) at Oak Ridge National Laboratory (ORNL) investigated the potential for producing a viable longburn tokamak reactor by enhancing the volt-second capability of the ohmic heating transformer through the use of high aspect ratio designs. The plasma physics, engineering, and economic implications of high aspect ratio tokamaks were assessed in the context of extended burn operation. Using a one-dimensional transport code plasma startup and burn parameters were addressed. The pulsed electrical power requirements for the poloidal field system, which have a major impact on reactor economics, were minimized by optimizing the startup and shutdown portions of the tokamak cycle. A representative large aspect ratio tokamak with an aspect ratio of 8 was found to achieve a burn time of 3.5 h at capital cost only approx. 25% greater than that of a moderate aspect ratio design tokamak

Ultrastructural and biochemical studies on formation of calcium oxalate in plants

International Nuclear Information System (INIS)

Abdelmottaleb, A.M.

1989-01-01

Plant calcium oxalate crystals occur within cells called crystal idioblasts. Important aspects of this calcification phenomenon have not been characterized. This dissertation examines some of the aspects of this ubiquitous type of calcification including (1) characterization of ultrastructural features of developing crystal idioblasts, (2) determination of the relationship of specialized ultrastructural features of the idioblasts to transport of compounds and mechanisms of crystal deposition, and (3) the biochemical relationship between ascorbic acid metabolism and production of oxalic acid used for crystal formation. Structural and cytochemical studies revealed that crystal idioblasts have dense cytoplasm, modified plastids, enlarged nuclei, extensive endoplasmic reticulum, numerous dictyosomes and vesicles, and a bundle of raphide crystals in their vacuoles. A mechanism for Ca transport and crystal precipitation is proposed, based on these results. There is a strong and dynamic relationship between Ca concentration and oxalic acid produced for crystal formation, where increasing Ca level in the growth medium lead to increased total and insoluble oxalate in the plant. Calmodulin antagonists reduced oxalic acid production

Yellow-headed temple turtles (YHT), Hieremys annandalii, native to Thailand, are protected from exploitation under the Wild Animal Reservation and Protection Act, also listed under Appendix II of the Convention on International Trade of Endangered Species and the International Union for the Conservation of Nature red list. The objectives of this study were to describe quantitative, morphologic, and cytochemical features of blood cells and plasma biochemical analytes of clinically healthy YHT. Blood samples were collected from 40 adult YHT from October 2007 to February 2008. Hematologic and biochemical analyses, cytochemical staining, and ultrastructural evaluation were performed using standard methods. Hematologic results (mean ± SD) included: RBC count, 0.275 ± .094 × 10(6) cells/μL; WBC count, 11.7 ± 6.6 × 10(3) cells/μL; heterophils, 29.4 ± 6.9%; eosinophils, 23.7 ± 5.3%; basophils, 21.2 ± 1.9%; lymphocytes, 14.8 ± 5.9%; and azurophils, 10.7 ± 5.3%. Erythrocytes stained dark red with peroxidase-staining. Periodic acid-Schiff stain could not differentiate between thrombocytes and lymphocytes. Thrombocytes contained cytoplasmic vacuoles, similar to mammalian platelets and those of birds and snakes. Heterophils and eosinophils were similar in structure and cytochemical staining characteristics to those of other turtles and reptiles. Structure of basophils was similar to avian basophils. Lymphocytes and azurophils had similar cytochemical staining compared with mammalian lymphocytes and monocytes. Mean MCHC, WBC counts, absolute azurophil counts, and plasma alanine aminotransferase activity were higher in male turtles than in females. Blood characteristics of YHT are species-specific, and this study can be served as a reference for future clinical studies and medical care of YHT. ©2011 American Society for Veterinary Clinical Pathology.

Sunflower broomrape (Orobanche cumana Wallr.) is a root holoparasitic angiosperm considered as one of the major constraints for sunflower production in Mediterranean areas. Breeding for resistance is regarded as the most effective, feasible, and environmentally friendly solution to control this parasite. However, the existing sources of genetic resistance are defeated by the continuous emergence of new more virulent races of the parasite. In this work, the interaction between sunflower and O. cumana has been analysed in order to gain insights into the mechanisms involved in resistance. Two sunflower genotypes were selected showing different behaviour against the new race F of O. cumana, HE-39998 (susceptible) and HE-39999 (resistant), and both compatible and incompatible interactions were compared. Pot and Petri dish bioassays revealed that only HE-39998 plants were severely affected, supporting a high number of successfully established broomrapes to mature flowering, whereas in HE-39999 root tubercles were never observed, resistance being associated with browning symptoms of both parasite and host tissues. Histological aspects of the resistance were further investigated. Suberization and protein cross-linking at the cell wall were seen in the resistant sunflower cells in contact with the parasite, preventing parasite penetration and connection to the host vascular system. In addition, fluorescence and confocal laser microscopy (CLM) observations revealed accumulation of phenolic compounds during the incompatible reaction, which is in agreement with these metabolites playing a defensive role during H. annuus-O. cumana interaction.

Cognitive aspects of color

Derefeldt, Gunilla A. M.; Menu, Jean-Pierre; Swartling, Tiina

1995-04-01

This report surveys cognitive aspects of color in terms of behavioral, neuropsychological, and neurophysiological data. Color is usually defined as psychophysical color or as perceived color. Behavioral data on categorical color perception, absolute judgement of colors, color coding, visual search, and visual awareness refer to the more cognitive aspects of color. These are of major importance in visual synthesis and spatial organization, as already shown by the Gestalt psychologists. Neuropsychological and neurophysiological findings provide evidence for an interrelation between cognitive color and spatial organization. Color also enhances planning strategies, as has been shown by studies on color and eye movements. Memory colors and the color- language connections in the brain also belong among the cognitive aspects of color.

Background and Aims Functional–structural plant models (FSPMs) are used to integrate knowledge and test hypotheses of plant behaviour, and to aid in the development of decision support systems. A significant amount of effort is being put into providing a sound methodology for building them. Standard techniques, such as procedural or object-oriented programming, are not suited for clearly separating aspects of plant function that criss-cross between different components of plant structure, which makes it difficult to reuse and share their implementations. The aim of this paper is to present an aspect-oriented programming approach that helps to overcome this difficulty. Methods The L-system-based plant modelling language L+C was used to develop an aspect-oriented approach to plant modelling based on multi-modules. Each element of the plant structure was represented by a sequence of L-system modules (rather than a single module), with each module representing an aspect of the element's function. Separate sets of productions were used for modelling each aspect, with context-sensitive rules facilitated by local lists of modules to consider/ignore. Aspect weaving or communication between aspects was made possible through the use of pseudo-L-systems, where the strict-predecessor of a production rule was specified as a multi-module. Key Results The new approach was used to integrate previously modelled aspects of carbon dynamics, apical dominance and biomechanics with a model of a developing kiwifruit shoot. These aspects were specified independently and their implementation was based on source code provided by the original authors without major changes. Conclusions This new aspect-oriented approach to plant modelling is well suited for studying complex phenomena in plant science, because it can be used to integrate separate models of individual aspects of plant development and function, both previously constructed and new, into clearly organized, comprehensive FSPMs. In

Verb aspect, alternations and quantification

Directory of Open Access Journals (Sweden)

Svetla Koeva

2015-11-01

Full Text Available Verb aspect, alternations and quantification In this paper we are briefly discuss the nature of Bulgarian verb aspect and argue that the verb aspect pairs are different lexical units with different (although related meaning, different argument structure (reflecting categories, explicitness and referential status of arguments and different sets of semantic and syntactic alternations. The verb prefixes resulting in perfective verbs derivation in some cases can be interpreted as lexical quantifiers as well. Thus the Bulgarian verb aspect is related (in different way both with the potential for the generation of alternations and with the prefixal lexical quantification. It is shown that the scope of the lexical quantification by means of verbal prefixes is the quantified verb phrase and the scope remains constant in all derived alternations. The paper concerns the basic issues of these complex problems, while the detailed description of the conditions satisfying particular alternation or particular lexical quantification are subject of a more detailed study.

Verbal aspect category and some ways of distinguishing of aspect pairs of verbs

Directory of Open Access Journals (Sweden)

Elena V. Sheyko

2016-09-01

Full Text Available The article discusses one of the most complex grammatical categories of the verb - category of the aspect, it is noted that there are still unsolved issues relating to the status of this category, its volume, ratio to the aspect pairs of verbs. One group of scientists after V.V. Vinogradov calls category of aspect as word-changing on the basis of the lexical identity of aspect pairs, another group, and in particular I.G. Miloslavsky, relates it to the formative, the third group, which representative is L.A. Mesenyashina, tryes to find a compromise, and those verbs, which syntactic-functional series are identical, calls paired, and those verbs in which there are significant differences in compatibility, calls different lexems. Thus it is accounted only the compatibility of verbs with the word forms, as well as many verbs can act as a reference in subordinate clauses, and in this case their compatibility in different lexical-semantic versions may vary. It is shown on the example of the verbs “чувствовать – почувствовать», which in the majority of lexicographical sources are named paired verbs, but their compatibility is not the same, and therefore, they can not be called as aspect pair. Therefore, in determining the pair/unpair verbs we should proceed from the same or not the same invariant meaning of verbs (in the terminology of A. Timberlake, take into account their multiple meanings and compatibility in different LSV and consider compatibility not only at the level of word forms, but also at the level of a complex sentence.

The purpose of this report is to document the environmental aspects and associated environmental impacts of the Bechtel SAIC Company (BSC) scope of work, evaluate the significance of those environmental aspects based on established criteria, and establish environmental objectives and targets for specific environmental aspects. This report is intended to be used by environmental staff in the evaluation of BSC work packages during the annual risk-based planning process. This report shall be fully reviewed and revised annually during the annual work planning process to reflect changes in BSC operations, facilities, and scope of work. Planned BSC work will be evaluated to determine if the work is covered by a previously defined activity, product or service (see Table 2); if work activities require redefinition or addition of a new activity; and if the significant evaluation for each environment aspect is still valid based on scope of planned work. New workscope initiated during the fiscal year through the Baseline Change Proposal process (i.e., not as part of the annual work plan) also will be reviewed for new environmental aspects and determination of whether the new workscope would change the significance rating of any environmental aspect. If a new environmental aspect is identified in a new work activity, product, or service but the aspect is not determined to be significant (see Section 4), then this report can be changed through an interim change notice (ICN). This report can be changed five times through an ICN before a full revision is required. However, if new workscope causes an environmental aspect to be graded as significant using the evaluation process in Section 4, this report shall be revised though a full review and revision

This study focuses on investigating the ability to expand UML to some extent to model crosscutting concerns (Aspects to support AspectJ. Through a comprehensive literature review, we identify and extensively examine all the available Aspect-Oriented UML modelling approaches and find that the existing Aspect-Oriented Design Modelling approaches using UML cannot be considered to provide a framework for a comprehensive Aspectual UML modelling approach and also that there is a lack of adequate Aspect-Oriented tool support. This study also proposes a set of Aspectual UML semantic rules and attempts to generate AspectJ pseudocode from UML diagrams.

Organisational aspects of care, the second essential skills cluster, identifies the need for registered nurses to systematically assess, plan and provide holistic patient care in accordance with individual needs. Safeguarding, supporting and protecting adults and children in vulnerable situations; leading, co-ordinating and managing care; functioning as an effective and confident member of the multidisciplinary team; and managing risk while maintaining a safe environment for patients and colleagues, are vital aspects of this cluster. This article discusses the roles and responsibilities of the newly registered graduate nurse. Throughout their education, nursing students work towards attaining this knowledge and these skills in preparation for their future roles as nurses.

Ranking product aspects through sentiment analysis of online reviews

Science.gov (United States)

Wang, Wei; Wang, Hongwei; Song, Yuan

The electronic word-of-mouth (e-WOM) is one of the most important among all the factors affecting consumers' behaviours. Opinions towards a product through online reviews will influence purchase decisions of other online consumers by changing their perceptions on the product quality. Furthermore, each product aspect may impact consumers' intentions differently. Thus, sentiment analysis and econometric models are incorporated to examine the relationship between purchase intentions and aspect-opinion pairs, which enable the weight estimation for each product aspect. We first identify product aspects and reduce dimensions to extract aspect-opinion pairs. Next the information gain is calculated for each aspect through entropy theory. Based on sentiment polarity and sentiment strength, we formulate an econometric model by integrating the information gain to measure the aspect's weight. In the experiment, we track 386 digital cameras on Amazon for 39 months, and results show that the aspect weight for digital cameras is detected more precisely than TF-ID and HAC algorithms. The results will bridge product aspects and consumption intention to facilitate e-WOM-based marketing.

Ethical aspects of nuclear power

International Nuclear Information System (INIS)

Streithofen, H.B.

1989-01-01

The nuclear controversy comprises many ethical aspects, e.g. the waste disposal problem. Nuclear opponents should not neglect the environmental protection aspect; for example, the use of nuclear power alone brought about an 8% reduction of the CO 2 burden in 1987. Our responsibility towards nature and humans in the Third World leaves us no alternative to nuclear power. On the other hand, the nuclear power debate should not become a matter of religious beliefs.

Modeling Submarine Lava Flow with ASPECT

Science.gov (United States)

Storvick, E. R.; Lu, H.; Choi, E.

2017-12-01

Submarine lava flow is not easily observed and experimented on due to limited accessibility and challenges posed by the fast solidification of lava and the associated drastic changes in rheology. However, recent advances in numerical modeling techniques might address some of these challenges and provide unprecedented insight into the mechanics of submarine lava flow and conditions determining its wide-ranging morphologies. In this study, we explore the applicability ASPECT, Advanced Solver for Problems in Earth's ConvecTion, to submarine lava flow. ASPECT is a parallel finite element code that solves problems of thermal convection in the Earth's mantle. We will assess ASPECT's capability to model submarine lava flow by observing models of lava flow morphology simulated with GALE, a long-term tectonics finite element analysis code, with models created using comparable settings and parameters in ASPECT. From these observations we will contrast the differing models in order to identify the benefits of each code. While doing so, we anticipate we will learn about the conditions required for end-members of lava flow morphology, for example, pillows and sheet flows. With ASPECT specifically we focus on 1) whether the lava rheology can be implemented; 2) how effective the AMR is in resolving morphologies of the solidified crust; 3) whether and under what conditions the end-members of the lava flow morphologies, pillows and sheets, can be reproduced.

Aspect Βased Classification Model for Social Reviews

Directory of Open Access Journals (Sweden)

J. Mir

2017-12-01

Full Text Available Aspect based opinion mining investigates deeply, the emotions related to one’s aspects. Aspects and opinion word identification is the core task of aspect based opinion mining. In previous studies aspect based opinion mining have been applied on service or product domain. Moreover, product reviews are short and simple whereas, social reviews are long and complex. However, this study introduces an efficient model for social reviews which classifies aspects and opinion words related to social domain. The main contributions of this paper are auto tagging and data training phase, feature set definition and dictionary usage. Proposed model results are compared with CR model and Naïve Bayes classifier on same dataset having accuracy 98.17% and precision 96.01%, while recall and F1 are 96.00% and 96.01% respectively. The experimental results show that the proposed model performs better than the CR model and Naïve Bayes classifier.

Some global aspects regarding nuclear spent fuel management

International Nuclear Information System (INIS)

Ohai, Dumitru; Postoaca, Marius Marcel

2002-01-01

The globalization means the worldwide extension of certain aspects of social or economic processes, structural or environmental changes, or concerning working methodologies, technical activity, industrial production, etc. At present the emergence of global aspects is more frequently observed, being determined by the rapid development of computerized systems and of transfer of information, by the development of big transnational companies and due to the increasing international co-operation. Some of the manifested global aspects could be beneficial for the development of the human society, other could be not. It is necessary to perform an adequate analysis from this view point and to promote appropriate measures to enhance the positive global aspects and to mitigate the negative global aspects. These measures can have a good efficiency only if they are pursued at global level, but for this it is necessary to build an adequate international coordinating body, having the corresponding instruments for action. The global aspects identified in the field of nuclear power may be divided into two categories, namely: - related to the main features of nuclear power; - regarding the specific features of some subdivisions of the field, as for example, spent fuel management. In the paper both categories are discussed. The influence of the global aspects on the development of nuclear power and particularly on the back end activities of the fuel cycle, is also presented. At the same time, some possible actions for enhancing nuclear power development are proposed

Full Text Available Carbohydrate-containing molecules were located on the surface of Candida lipolytica by using ruthenium red in a cytochemical study. The yeast was grown in media containing Tween 80. The surfactant, at 1.0% and 0.5%, was added to the culture medium in different intervals of time, correspondent to the beginning of exponential growth phase, mid of logarithimic phase and beginning of stationary growth phase. Control cultures were grown in a medium containing glucose. The growth of the yeast in media containing glucose and Tween 80 induced changes in the pattern of distribution and location of acid polyssacharides in the cell wall of the microorganism. In adition, the pattern also changed according to Tween 80 concentration. The influence of Tween 80 on cellular carbohydrate expression is discussed.Moléculas contendo resíduos de açúcares foram localizadas sobre a superfície de Candida lipolytica utilizando-se o vermelho de rutênio como marcador citoquímico.

Full Text Available Purpose. Uterine artery embolization is a minimally invasive technique. It applies the principle of targeted anatomical structure devascularisation with utility in fibroid conservative therapy, including for future fertility preserving status. The objective of our paper represents a description and evaluation of angiography utility as a predictive method for fertility maintenance. Material and Methods. The angiography and ultrasound aspects obtained from a prospective study in which selected patients have undergone uterine artery embolization for fertility preservation are detailed. Results. The following angiography aspects have been detected: left- right shunt and utero-ovarian collaterals; these have been compared with the ultrasound aspects related to the fibroid evolution form a volumetric and Doppler ultrasound point of view. The angiographical description predicts the impact on post embolization fibroid evolution and upon fertility. An analysis is made in order to assess the way in which angiography can contribute to fertility alteration. Conclusions. The angiography aspects during embolization and the following ultrasound aspects can represent predictive factors as to fertility evolution after uterine artery embolization.

Discovering Socio-cultural Aspects of Science Through Artworks

Science.gov (United States)

Güney, Burcu Gülay; Şeker, Hayati

2017-11-01

Scientific literacy is one of the primary purposes of science education which briefly focuses on using and interpreting scientific explanations, understanding science within its culture. However, science curricula emphasize science with its cognitive aspects and underestimate affective and aesthetic aspects of science. Science education needs to cover beauty of science for students to cross borders between their own culture and culture of science and to achieve the aim of scientific literacy. Relating aesthetic aspects of science with content of science and paving the way for aesthetic experiences through artworks may enrich science education. The purposes of this study are to discuss the need of integrating aesthetic aspects of science in science instruction and to propose examples and pedagogical suggestions to promote aesthetic experiences into the science education. Artworks are selected to present socio-cultural aspects of science to demonstrate the culture of science, their stories are explained, and pedagogical suggestions are proposed. Advantages and difficulties of using artworks in science instruction are discussed as a result of the study.

Behavioural aspects of terrorism.

Leistedt, Samuel J

2013-05-10

Behavioural and social sciences are useful in collecting and analysing intelligence data, understanding terrorism, and developing strategies to combat terrorism. This article aims to examine the psychopathological concepts of terrorism and discusses the developing roles for behavioural scientists. A systematic review was conducted of studies investigating behavioural aspects of terrorism. These studies were identified by a systematic search of databases, textbooks, and a supplementary manual search of references. Several fundamental concepts were identified that continue to influence the motives and the majority of the behaviours of those who support or engage in this kind of specific violence. Regardless of the psychological aspects and new roles for psychiatrists, the behavioural sciences will continue to be called upon to assist in developing better methods to gather and analyse intelligence, to understand terrorism, and perhaps to stem the radicalisation process.

To this end, a UML profile has been developed for the specification of security hardening aspects on UML diagrams. In addition, a weaving framework, with the underlying theoretical foundations, has been designed for the systematic injection of security aspects into UML models. The

Following the Social Media: Aspect Evolution of Online Discussion

Science.gov (United States)

Tang, Xuning; Yang, Christopher C.

Due to the advance of Internet and Web 2.0 technologies, it is easy to extract thousands of threads about a topic of interest from an online forum but it is nontrivial to capture the blueprint of different aspects (i.e., subtopic, or facet) associated with the topic. To better understand and analyze a forum discussion given topic, it is important to uncover the evolution relationships (temporal dependencies) between different topic aspects (i.e. how the discussion topic is evolving). Traditional Topic Detection and Tracking (TDT) techniques usually organize topics as a flat structure but it does not present the evolution relationships between topic aspects. In addition, the properties of short and sparse messages make the content-based TDT techniques difficult to perform well in identifying evolution relationships. The contributions in this paper are two-folded. We formally define a topic aspect evolution graph modeling framework and propose to utilize social network information, content similarity and temporal proximity to model evolution relationships between topic aspects. The experimental results showed that, by incorporating social network information, our technique significantly outperformed content-based technique in the task of extracting evolution relationships between topic aspects.

Optimizing Aspect-Oriented Mechanisms for Embedded Applications

Science.gov (United States)

Hundt, Christine; Stöhr, Daniel; Glesner, Sabine

As applications for small embedded mobile devices are getting larger and more complex, it becomes inevitable to adopt more advanced software engineering methods from the field of desktop application development. Aspect-oriented programming (AOP) is a promising approach due to its advanced modularization capabilities. However, existing AOP languages tend to add a substantial overhead in both execution time and code size which restricts their practicality for small devices with limited resources. In this paper, we present optimizations for aspect-oriented mechanisms at the level of the virtual machine. Our experiments show that these optimizations yield a considerable performance gain along with a reduction of the code size. Thus, our optimizations establish the base for using advanced aspect-oriented modularization techniques for developing Java applications on small embedded devices.

Lacroix, D.

2003-01-01

In this lecture, we present selected aspects of nuclear fusion. The importance of the initial geometry of the reaction and its relation to fusion barrier are first discussed. The effect of deformation leading to the notion of barrier distribution is then illustrated. After a brief overview of the advantages of macroscopic theories, the dynamics of nuclear system under large amplitude motion is reviewed. The di-nuclear concept is presented to understand the competition between fusion and quasi-fission. This concept is then generalized to account for the dissipative dynamics in multidimensional collective space. The last part of this lecture is devoted to new aspects encountered with radioactive beams specific properties of very extended neutron rich system, influence of pygmy or soft dipole resonances and charge exchange far from stability are discussed.

Transport in a small aspect ratio torus

International Nuclear Information System (INIS)

White, R.B.; Gates, D.A.; Mynick, H.E.

2005-01-01

Transport theory in toroidal devices often assumes large aspect ratio and also assumes the poloidal field is small compared to the toroidal field. These assumptions result in transport which in the low collision rate limit is dominated by banana orbits, giving the largest collisionless excursion of a particle from an initial flux surface. However in a small aspect ratio device the gyro radius may be larger than the banana excursion, resulting in significant deviations from the standard neoclassical predictions. In this paper we report numerical simulation of diffusion in low and high beta low aspect ratio equilibria. We also sketch an analytic theory. The diffusion, which we refer to as omniclassical, is a combination of neoclassical and properly averaged classical effects, and can be two or three times the neoclassical value. Good agreement of the analytic theory with numerical simulations is obtained. (author)

Integer Linear Programming for Constrained Multi-Aspect Committee Review Assignment

Science.gov (United States)

Karimzadehgan, Maryam; Zhai, ChengXiang

2011-01-01

Automatic review assignment can significantly improve the productivity of many people such as conference organizers, journal editors and grant administrators. A general setup of the review assignment problem involves assigning a set of reviewers on a committee to a set of documents to be reviewed under the constraint of review quota so that the reviewers assigned to a document can collectively cover multiple topic aspects of the document. No previous work has addressed such a setup of committee review assignments while also considering matching multiple aspects of topics and expertise. In this paper, we tackle the problem of committee review assignment with multi-aspect expertise matching by casting it as an integer linear programming problem. The proposed algorithm can naturally accommodate any probabilistic or deterministic method for modeling multiple aspects to automate committee review assignments. Evaluation using a multi-aspect review assignment test set constructed using ACM SIGIR publications shows that the proposed algorithm is effective and efficient for committee review assignments based on multi-aspect expertise matching.

Slosárek, M

1977-01-01

It was the aim of the present communication to find a simple test for a reliable discrimination of Mycobacterium bovis BCG from Mycobacterium tuberculosis. A total of 26 BCG strains, out of them 10 Czechoslovak strains (2 lyophilized cultures of BCG of different batch, 6 strains isolated from abscesses of children after BCG-vaccination and 2 strains from fatal cases after BCG-vaccination) and 16 strains obtained from foreign laboratories, were used. Of the tested characteristics a combination of 3 tests, sensitivity to 1 microgram of 2-thiophene carbonylhydrazide (TCH), activity of 3 acylamidases (urease, nicotinamidase and pyrazinamidase) and a quantitative nitrate test, was found to be most advantageous. The Czechoslovak strains of Mycobacterium bovis BCG were fully sensitive to TCH, of the 3 acylamidases mentioned above only urease was positive and nitrate was reduced only little or not at all. On the other hand, strains of Mycobacterium tuberculosis were always resistant to TCH, had positive urease, nicotinamidase and pyrazinamidase and reduced nitrate very intensively.

Modifications in bull sperm plasmamembrane during epididymal passage were investigated by the use of four different lectins: Concanavalin A (Con A); Ricinus communis I (RCA1); Wheat germ agglutinin (WGA); Ulex europaeus agglutinin I (UEA1). During sperm passage from caput to cauda epididymidis agglutination by RCA1 and WGA distinctly increased. Similar but somewhat less pronounced difference in the agglutinability was found for Con A. No agglutination was observed with UEA1. Ultrastructural examination of Con A binding sites on sperm plasma membrane with a Con A-horseradish peroxidase-gold technique (Con A-HRP-G) revealed a significant increase in the number of gold granules on the sperm tails during the epididymal passage of spermatozoa. No change in WGA-binding sites was observed between caput and cauda spermatozoa using a WGA-peroxidase method.

We propose that the geometric and standard gauge field aspects of gravity are equally essential for a complete description of gravity and can be reconciled. We show that this dualism of gravity resolves the dimensional Newtonian constant problem in both quantum gravity and unification schemes involving gravity (i.e., the Newtonian constant is no longer the coupling constant in the gauge aspect of gravity) and reveals the profound similarity between gravity and other fields. 23 refs., 3 tabs

This paper seeks to determine the variousdegrees of remoteness to a given tense category exhibited in Lamnso’. This paper investigates the relative relationship(s between a tense marker that denotes the time of an action and the time reference preceding or following that action within the clause. It also examines aspect, interpreted as the way of conceiving the flow of an event (Comrie, 1976. This study identifies seven tense forms for Lamnso’ (P3, P2, P1, P0, F1, F2 and F3., which specify time distinctions from the remote past (P3 to the remote future (F3 and three aspect forms. These ten tense and aspect forms combine with distinctive tones and time adverbials to derive a time reference structure whose cut-off points are sometimes fluid and non-rigid.

Agbessi, Odry; Arrob, Adil; Fiqhi, Kamal; Khalfi, Lahcen; Nassih, Mohammed; El Khatib, Karim

2015-01-01

Décrit la première fois par Virchow en 1860, le liposarcome est une tumeur mésenchymateuse rare. Cette rareté est relative car les liposarcomes représentent quand même 14 à 18% de l'ensemble des tumeurs malignes des parties molles et ils constituent le plus fréquent des sarcomes des parties molles. Pour la majorité des auteurs, il ne se développerait jamais sur un lipome ou une lipomatose préexistant. Nous rapportons un cas de volumineux liposarcome de la face dorsale du tronc. L'histoire de la maladie, l'aspect clinique inhabituel « de tumeur dans tumeur », l'aspect de la pièce opératoire nous fait évoquer la possibilité de la transformation maligne d'un lipome bénin préexistant.

Summary of session D2: quantum aspects of cosmology

International Nuclear Information System (INIS)

Bojowald, Martin

2008-01-01

This is a summary of talks about quantum aspects of cosmology. Topics involve the properties of quantum matter fields on an expanding spacetime as well as issues in the quantization of gravity itself. This session had three parts, one of which was in a joint session with quantum aspects of black holes (D1) and other quantum aspects (D3). The first block of talks was related to quantum aspects of field theories on a classical spacetime (with possible back-reaction), while the second block dealt in several ways with quantizations of gravity itself. The two talks in the combined session discussed issues in quantum theory on de Sitter space and will therefore be included here in the summary of the first block. For each talk, a reference is given for further details

These proceedings include 29 reports presented by Soviet scientists during the four sessions as well as summaries of discussions and opening addresses. Refs, figs and tabs

Microeconomic aspects of energy crops cultivation

International Nuclear Information System (INIS)

Bartolelli, V.; Mutinati, G.; Pisani, F.

1992-01-01

The topic of energy crops, namely of those crops designed to produce biomass to transform into ethanol, has been explored, in Italy and abroad, in all its technical and agronomical aspects. The microeconomic aspect, including the evaluation of convenience for the farmer in adopting such crops, is, on the contrary, less well researched. RENAGRI has developed a research methodology able to give information about the level of convenience of two energy crops (Sweet Sorghum and Topinambour) and has applied it to different Italian agricultural situations, in order to verify the existence of conditions favourable to the cultivation of the two crops, or to indicate the necessity of eventual subvention.

2007-01-01

This comprehensive article summarises the commercial aspects of a study made by the German Association of Electrical, Electronic and Information Technologies VDE on the topic of decentralised energy supply in the year 2020. In a previous article, the technical aspects were examined. This article looks at the findings in connection with commercial aspects of the production of power in decentralised facilities including those using renewable sources of energy. The potential of these forms of electricity generation for the year 2020 is looked at both from the political and economical points of view. The general conditions prevailing for the implementation of decentralised power production in Germany such as the Renewable Energy Law and legislation on combined heat and power generation are discussed. The influence of electricity tariffs and competition in the market is examined, as are various scenarios and concepts for the supply of both power and heating energy. Ways of providing a sustainable energy supply without having to subsidise particular concepts are discussed

Chen, Yu-Cheng; Wang, Yan; McCarthy, Thomas J; Crosby, Alfred J

2017-06-07

Wrinkle aspect ratio, or the amplitude divided by the wavelength, is hindered by strain localization transitions when an increasing global compressive stress is applied to synthetic material systems. However, many examples from living organisms show extremely high aspect ratios, such as gut villi and flower petals. We use three experimental approaches to demonstrate that these high aspect ratio structures can be achieved by modifying the network stress in the wrinkle substrate. We modify the wrinkle stress and effectively delay the strain localization transition, such as folding, to larger aspect ratios by using a zero-stress initial wavy substrate, creating a secondary network with post-curing, or using chemical stress relaxation materials. A wrinkle aspect ratio as high as 0.85, almost three times higher than common values of synthetic wrinkles, is achieved, and a quantitative framework is presented to provide understanding the different strategies and predictions for future investigations.

Full Text Available Several semantic and syntactic distinctions, which have largely been neglected in the Vietnamese linguistic literature, are drawn together in this paper in a comparative context with other better-studied languages in order to indicate that Inner Aspect is projected within the VP shell and independently of the projection of Outer Aspect – a structural proposal originally advanced by Travis (2010. Overall, Vietnamese with its isolating character and rigid word order provides us with unusually direct evidence for an articulated VP structure.

Sentiment Analysis on Tweets about Diabetes: An Aspect-Level Approach

KAUST Repository

Salas-Zárate, María del Pilar

2017-02-19

In recent years, some methods of sentiment analysis have been developed for the health domain; however, the diabetes domain has not been explored yet. In addition, there is a lack of approaches that analyze the positive or negative orientation of each aspect contained in a document (a review, a piece of news, and a tweet, among others). Based on this understanding, we propose an aspect-level sentiment analysis method based on ontologies in the diabetes domain. The sentiment of the aspects is calculated by considering the words around the aspect which are obtained through N-gram methods (N-gram after, N-gram before, and N-gram around). To evaluate the effectiveness of our method, we obtained a corpus from Twitter, which has been manually labelled at aspect level as positive, negative, or neutral. The experimental results show that the best result was obtained through the N-gram around method with a precision of 81.93%, a recall of 81.13%, and an -measure of 81.24%.

2007-01-01

AMFIBIA is a meta-model that formalises the essential aspects and concepts of business processes. Though AMFIBIA is not the first approach to formalising the aspects and concepts of business processes, it is more ambitious in the following respects: Firstly, it is independent from particular...... modelling formalisms of business processes and it is designed in such a way that any formalism for modelling some aspect of a business process can be plugged into AMFIBIA. Therefore, AMFIBIA is formalism-independent. Secondly, it is not biased toward any aspect of business processes; the different aspects...... can be considered and modelled independently of each other. Moreover, AMFIBIA is not restricted to a fixed set of aspects; new aspects of business processes can be easily integrated. Thirdly, AMFIBIA does not only name and relate the concepts of business process modelling, as it is typically done...

Optimization method concerning target conflicts between safety aspects and occupational safety aspects in nuclear power plant operations

International Nuclear Information System (INIS)

Mueller, W.

1991-01-01

The simplified cost-benefit analysis has not been considered for applications in nuclear engineering with complex decisions between safety aspects and occupational safety aspects. The extended cost-benefit analysis encounters problems with non-monetary criteria. Solutions are in sight, however with a subjective element. A major problem in implementing the method is the psychological barrier as against an evaluation of human life. The multi-attribute utility analysis overcomes the difficulties of the extended cost-benefit analysis, however, it also creates new problems on account of the complicated construction of the utility functions. The problems are solved most elegantly with the multi-criteria outranking analysis, the only disadvantage possibly being less transparency at first sight. (orig./HP) [de

Two often disregarded aspects of Foucault's pendulum

International Nuclear Information System (INIS)

Pérez, José-Philippe; Pujol, Olivier

2015-01-01

This paper revisits the famous Foucault's pendulum by highlighting two often-disregarded aspects in mechanics courses. The first one concerns the existence of a local accelerated reference frame to express the law of dynamics without the Coriolis force. The second aspect deals with the geometrical phase that appears in pendulum dynamics. This last point, which could appear banal, should be related to analogous consideration in quantum physics. It is also linked to vectorial parallel transport of the pendulum angular momentum eigenvector. Numerical simulations with MATLAB are proposed. (paper)

[Gender (role) aspects in doctor-patient communication].

Science.gov (United States)

Sieverding, M; Kendel, F

2012-09-01

Aspects of gender and gender roles are important factors influencing the interactions between physicians and their patients. On the one hand, gender roles have an impact on the behavior of the patients, such as in health care utilization or use of preventive examinations. On the other hand, gender issues influence doctors' actions with respect to communication, diagnosis, and treatment. Here, a gender bias may lead to misdiagnosis and inadequate treatment. In this paper certain pertinent aspects of gender roles in the doctor-patient relationship are discussed and illustrated by empirical findings.

Several cities in Indonesia have the sewerage local regulation such as Banjarmasin, Bantul, Surakarta and Denpasar. Meanwhile, The National Government have guideline in composing domestic sewerage regulation. Each city have their own characteristic and issues that need to be carried out by the local regulation. By using SWOT analysis, this study tries to figure out several aspect that need to be included in the local regulation. International references from developed and developing countries like Japan, Phillipines, Malaysia and Thailand were also used as benchmark without neglecting the local conditions of cities in Indonesia. Several crucial aspect of local regulation are institutional authority, composition on-site and off-site system, tariff, evaluation and monitoring, as well as punishment and rewards. Both tariff and evaluation aspects need to be narrowed down into specific regulations.

Economic aspects of radionuclide production for nuclear medicine

1980-03-01

In a difficult economic situation it was considered advisable to inform users of certain financial aspects of radionuclide production for nuclear medicine. Two aspects of this vast and many-sided problem are developed here: - The cost price structure of different products (radiopharmaceutical and radioimmunological) which defines the size of the market consistent with a balanced budget. This aspect of the economic analysis seems all the more important as ORIS, although a non profit-making organization, has to balance its production costs. - The effects on the national economy of the nuclear medicine supply market. From this viewpoint it seemed interesting to examine the share-out of the French market between ORIS which is practically the only national producer and importers, as well as the balance of payments situation in this respect [fr

Ethical aspects on rare diseases.

Barrera, Luis A; Galindo, Gilberto Cely

2010-01-01

In this chapter we discuss several of the most relevant subjects related to ethics on Rare Diseases. Some general aspects are discussed such as the socio-psychological problems that confront the patients and their families that finally lead to marginalization and exclusion of patients affected by these diseases from the health programs, even in wealthy countries. Then we address problems related to diagnosis and some ethical aspects of newborn screening, prenatal, pre-implantation diagnosis and reference centers, as well as some conditions that should be met by the persons and institutions performing such tasks. Alternatives of solutions for the most critical situations are proposed. Subsequently the orphan drugs subject is discussed not only from the availability point of view, prizes, industrial practices, and purchasing power in developed and developing societies. The research related to rare disease in children and other especially vulnerable conditions, the need for informed consent, review boards or ethics comities, confidentiality of the information, biobanks and pharmacogenetics are discussed.

Aspect-object alignment with Integer Linear Programming in opinion mining.

Directory of Open Access Journals (Sweden)

Yanyan Zhao

Full Text Available Target extraction is an important task in opinion mining. In this task, a complete target consists of an aspect and its corresponding object. However, previous work has always simply regarded the aspect as the target itself and has ignored the important "object" element. Thus, these studies have addressed incomplete targets, which are of limited use for practical applications. This paper proposes a novel and important sentiment analysis task, termed aspect-object alignment, to solve the "object neglect" problem. The objective of this task is to obtain the correct corresponding object for each aspect. We design a two-step framework for this task. We first provide an aspect-object alignment classifier that incorporates three sets of features, namely, the basic, relational, and special target features. However, the objects that are assigned to aspects in a sentence often contradict each other and possess many complicated features that are difficult to incorporate into a classifier. To resolve these conflicts, we impose two types of constraints in the second step: intra-sentence constraints and inter-sentence constraints. These constraints are encoded as linear formulations, and Integer Linear Programming (ILP is used as an inference procedure to obtain a final global decision that is consistent with the constraints. Experiments on a corpus in the camera domain demonstrate that the three feature sets used in the aspect-object alignment classifier are effective in improving its performance. Moreover, the classifier with ILP inference performs better than the classifier without it, thereby illustrating that the two types of constraints that we impose are beneficial.

Aspects of leak before break quantification in pressurized pipes

International Nuclear Information System (INIS)

Hellen, R.A.J.; Darlaston, B.J.L.; Connors, D.C.

1980-01-01

In fitness for purpose studies of pressurized structures containing defects, the concept of leak before break is often invoked. As the assumptions used in the concept are sometimes very pessimistic it is desirable to be able to quantify them more precisely. Two aspects are currently receiving attention; these are the way in which a crack profile develops during fatigue and what happens when the remaining ligament below the crack fails. These aspects are being evaluated experimentally and theoretically. Data are presented from tests on pipes subjected to cyclic pressure and subsequently failed. An analytical approach is proposed on the question of ligament failure, this being based on the development of some recent work on flat plates. The overall question of leak before break is considered. As the understanding and confidence increases, it is possible to reduce the range of interest and focus on specific aspects of the problem. This paper examines these aspects. (author)

ITER plasma control design solutions and performance requirements are strongly driven by its nuclear mission, aggressive commissioning constraints, and limited number of operational discharges. In addition, high plasma energy content, heat fluxes, neutron fluxes, and very long pulse operation place novel demands on control performance in many areas ranging from plasma boundary and divertor regulation to plasma kinetics and stability control. Both commissioning and experimental operations schedules provide limited time for tuning of control algorithms relative to operating devices. Although many aspects of the control solutions required by ITER have been well-demonstrated in present devices and even designed satisfactorily for ITER application, many elements unique to ITER including various crucial integration issues are presently under development. We describe selected novel aspects of plasma control in ITER, identifying unique parts of the control problem and highlighting some key areas of research remaining. Novel control areas described include control physics understanding (e.g., current profile regulation, tearing mode (TM) suppression), control mathematics (e.g., algorithmic and simulation approaches to high confidence robust performance), and integration solutions (e.g., methods for management of highly subscribed control resources). We identify unique aspects of the ITER TM suppression scheme, which will pulse gyrotrons to drive current within a magnetic island, and turn the drive off following suppression in order to minimize use of auxiliary power and maximize fusion gain. The potential role of active current profile control and approaches to design in ITER are discussed. Issues and approaches to fault handling algorithms are described, along with novel aspects of actuator sharing in ITER.

Grammatical Aspect and Gesture in French: A kinesiological approach

Directory of Open Access Journals (Sweden)

Доминик Бутэ

2016-12-01

Full Text Available In this paper, we defend the idea that research on Gesture with Speech can provide ways of studying speakers’ conceptualization of grammatical notions as they are speaking. Expressing an idea involves a dynamic interplay between our construal, shaped by the sensori-motoric and interactive experiences linked to that idea, the plurisemiotic means at our disposal for expressing it, and the linguistic category available for its expression in our language. By analyzing the expression of aspect in Speech with Gesture (GeSp in semi-guided oral interactions, we would like to make a new contribution to the field of aspect by exploring how speakers’ construal of aspectual differences grammaticalized in their language, may be enacted and visible in gesture. More specifically we want to see the degree to which event structure differences expressed in different grammatical aspects (perfective and imperfective correlate with kinesiological features of the gestures. To this end, we will focus on the speed and flow of the movements as well as on the segments involved (fingers, hand, forearm, arm, shoulder. A kinesiological approach to gestures enables us to analyze the movements of human bodies according to a biomechanical point of view that includes physiological features. This study is the first contribution focused on the links between speech and gesture in French in the domain of grammatical aspect. Grammatical aspect was defined by Comrie (1976 [1989] as involving the internal unfurling of the process, «[...] tense is a deictic category, i.e. locates situations in time, usually with reference to the present moment [...]. Aspect is not concerned with relating time of the situation to any other time-point, but rather with the internal temporal constituency of the one situation; one could state the difference as one between situation-internal time (aspect and situation-external time (tense » (Comrie, 1976 [1989]: 5.

Sentiment Analysis on Tweets about Diabetes: An Aspect-Level Approach

Directory of Open Access Journals (Sweden)

María del Pilar Salas-Zárate

2017-01-01

Full Text Available In recent years, some methods of sentiment analysis have been developed for the health domain; however, the diabetes domain has not been explored yet. In addition, there is a lack of approaches that analyze the positive or negative orientation of each aspect contained in a document (a review, a piece of news, and a tweet, among others. Based on this understanding, we propose an aspect-level sentiment analysis method based on ontologies in the diabetes domain. The sentiment of the aspects is calculated by considering the words around the aspect which are obtained through N-gram methods (N-gram after, N-gram before, and N-gram around. To evaluate the effectiveness of our method, we obtained a corpus from Twitter, which has been manually labelled at aspect level as positive, negative, or neutral. The experimental results show that the best result was obtained through the N-gram around method with a precision of 81.93%, a recall of 81.13%, and an F-measure of 81.24%.

What’s Done is Done: Verb Aspect and Verbatim Memory

Directory of Open Access Journals (Sweden)

Meghan Salomon-Amend

2017-09-01

Full Text Available Grammatical verb aspect uses morphosyntactic cues (‘-ed’, ‘-ing’ to convey whether an action is, for example, complete (“walked” or on-going (“was walking” and has shown notable comprehension ramifications for a reader’s event model. Additionally, research suggests that the reader quickly forgets verbatim surface-form information, such as morphosyntactic cues, while the event model remains intact. The current study used three different memory tests to probe readers’ event models of the texts, testing readers’ event model at retrieval. More importantly, we explored whether participants could have biased memory for the perfective aspect consistent with events unfolding in the narrative world. We show that verbs in the perfective aspect were remembered more accurately than those in the imperfective aspect. Moreover, imperfective verbs had a stronger tendency to be misremembered as being in the perfective aspect. That is, readers’ memory seems to be affected by the passage of narrative time, rather than maintaining fidelity to the temporal status of the verb at original presentation.

Aspect-Oriented Model-Driven Software Product Line Engineering

Science.gov (United States)

Groher, Iris; Voelter, Markus

Software product line engineering aims to reduce development time, effort, cost, and complexity by taking advantage of the commonality within a portfolio of similar products. The effectiveness of a software product line approach directly depends on how well feature variability within the portfolio is implemented and managed throughout the development lifecycle, from early analysis through maintenance and evolution. This article presents an approach that facilitates variability implementation, management, and tracing by integrating model-driven and aspect-oriented software development. Features are separated in models and composed of aspect-oriented composition techniques on model level. Model transformations support the transition from problem to solution space models. Aspect-oriented techniques enable the explicit expression and modularization of variability on model, template, and code level. The presented concepts are illustrated with a case study of a home automation system.

Full Text Available Objective To investigate the correlation between the Alberta Program Early CT Score (ASPECTS and the Scandinavian Stroke Scale (SSS for the evaluation of neurological impairment in patients with acute stroke. Method 59 patients with a first acute ischemic stroke were evaluated. The ASPECTS were evaluated by 2 neurologists at admission and by another neurologist after 48 hours. The NIHSS and SSS was applied to determinate stroke severity. Correlations and agreements were analysed statistically by Spearman and Kappa tests. Results ASPECTS was correlated with National Institute of Health Stroke Scale (NIHSS at admission (r = -0.52; p < 0.001 and SSS (r = 0.50; p < 0.001. The ASPECTS and SSS items were most correlated with arm (r = 0.52; p < 0.001 and hand (r = 0.49; p < 0.001 motor power, and speech (r = 0.51; p < 0.001. The SSS of 25.5 shows sensitivity (68% and specificity (72% when associated with ASPECTS ≤ 7. Conclusion The SSS can predict worst neurological impairment when associated with lower values of ASPECTS.

2004-01-01

Besides technical, political and economic aspects of energy sustainability there are several social, behavioural and psychological dimensions of vital importance for a successful implementation of Renewable Energy Systems (RES) and Rational Use of Energy (RUE) within communities. The European Project ''Sustainable Communities-on the energy dimension'' pursues an interdisciplinary approach to detect essential success and facilitating factors. In the last years social and psychological aspects in the process of sustainability came to the fore more and more. Not only as a complementary science to facilitate the technical aims in the change process but also as an essential part for success. (authors)

Myocardial Na,K-ATPase: Clinical aspects

Science.gov (United States)

Kjeldsen, Keld

2003-01-01

The specific binding of digitalis glycosides to Na,K-ATPase is used as a tool for Na,K-ATPase quantification with high accuracy and precision. In myocardial biopsies from patients with heart failure, total Na,K-ATPase concentration is decreased by around 40%; a correlation exists between a decrease in heart function and a decrease in Na,K-ATPase concentration. During digitalization, around 30% of remaining pumps are occupied by digoxin. Myocardial Na,K-ATPase is also influenced by other drugs used for the treatment of heart failure. Thus, potassium loss during diuretic therapy has been found to reduce myocardial Na,K-ATPase, whereas angiotensin-converting enzyme inhibitors may stimulate Na,K pump activity. Furthermore, hyperaldosteronism induced by heart failure has been found to decrease Na,K-ATPase activity. Accordingly, treatment with the aldosterone antagonist, spironolactone, may also influence Na,K-ATPase activity. The importance of Na,K pump modulation with heart disease, inhibition in digitalization and other effects of medication should be considered in the context of sodium, potassium and calcium regulation. It is recommended that digoxin be administered to heart failure patients who, after institution of mortality-reducing therapy, still have heart failure symptoms, and that the therapy be continued if symptoms are revealed or reduced. Digitalis glycosides are the only safe inotropic drugs for oral use that improve hemodynamics in heart failure. An important aspect of myocardial Na,K pump affection in heart disease is its influence on extracellular potassium (Ke) homeostasis. Two important aspects should be considered: potassium handling among myocytes, and effects of potassium entering the extracellular space of the heart via the bloodstream. It should be noted that both of these aspects of Ke homeostasis are affected by regulatory aspects, eg, regulation of the Na,K pump by physiological and pathophysiological conditions, as well as by medical

QCD-instantons at LHC. Theoretical aspects

International Nuclear Information System (INIS)

Petermann, M.

2007-06-01

Instantons are nonperturbative, topologically nontrivial field configurations, which occur in every nonabelian gauge theory. They can be understood as tunneling processes between topologically distinct vacua. Although being a basic theoretical aspect of the Standard Model, a direct experimental verification of instanton processes is still lacking. In this thesis the general discovery potential for QCD-instantons at the LHC is studied in detail by means of instanton perturbation theory. In this context the close correspondence between the leading instanton induced processes at HERA and at LHC becomes important. Essential aspects and differences to deep inelastic scattering can already be revealed by studying the simplest process. Based on these results inclusive cross sections are calculated including the emission of final state gluons. Compared to deep inelastic scattering, a large enhancement of the cross section is found.

New Vehicle Detection Method with Aspect Ratio Estimation for Hypothesized Windows

Directory of Open Access Journals (Sweden)

Jisu Kim

2015-12-01

Full Text Available All kinds of vehicles have different ratios of width to height, which are called the aspect ratios. Most previous works, however, use a fixed aspect ratio for vehicle detection (VD. The use of a fixed vehicle aspect ratio for VD degrades the performance. Thus, the estimation of a vehicle aspect ratio is an important part of robust VD. Taking this idea into account, a new on-road vehicle detection system is proposed in this paper. The proposed method estimates the aspect ratio of the hypothesized windows to improve the VD performance. Our proposed method uses an Aggregate Channel Feature (ACF and a support vector machine (SVM to verify the hypothesized windows with the estimated aspect ratio. The contribution of this paper is threefold. First, the estimation of vehicle aspect ratio is inserted between the HG (hypothesis generation and the HV (hypothesis verification. Second, a simple HG method named a signed horizontal edge map is proposed to speed up VD. Third, a new measure is proposed to represent the overlapping ratio between the ground truth and the detection results. This new measure is used to show that the proposed method is better than previous works in terms of robust VD. Finally, the Pittsburgh dataset is used to verify the performance of the proposed method.

Molen, Yara Fleury; Carvalho, Luciane Bizari Coin; Prado, Lucila Bizari Fernandes do; Prado, Gilmar Fernandes do

2014-01-01

Insomnia involves difficulty in falling asleep, maintaining sleep or having refreshing sleep. This review gathers the existing informations seeking to explain insomnia, including those that focus on psychological aspects and those considered neurobiological. Insomnia has been defined in psychological (cognitive components, such as worries and rumination, and behavioral aspects, such as classic conditioning) and physiological terms (increased metabolic rate, with increased muscle tone, heart rate and temperature). From the neurobiological point of view, there are two perspectives: one which proposes that insomnia occurs in association with a failure to inhibit wakefulness and another that considers hyperarousal as having an important role in the physiology of sleep. The non-pharmacological interventions developed to face different aspects of insomnia are presented.

Ethics can be defined as a reflection on nature and a definition of “the good”. Individuals value qualities and things dissimilarly, most visibly, but they also value their goods in different ways, in different relations to each other, for different reasons, and to different ends. These differences are very applicable to sustainability. In other words, sustainability cannot be achieved without attention to its ethical dimensions. The aim of this research is to examine the ethical aspects of s...

Phenomenological aspects of unified theories

Peccei, R.D.

1987-01-01

The author briefly discusses two new phenomena of recent interest, the 5/sup th/ force and variant axions. The former, for its elucidation, will require further gravitational experiments, but the author concludes that variant axions are now definitely rules out experimentally. Various aspects of superstring phenomenology are then addressed, including some of the generic predictions of superstrings and some of its generic problems. In particular, he discusses some of the phenomenological consequences of having an extra Z 0 boson and the circumstances under which this excitation is a genuine prediction of superstrings. Since it is likely that a more reliable relic of superstrings will be provided by the presence of superpartners at low energy (≤ TeV), he discusses some of the bounds for squarks and gluinos obtained at the SppS collider and the expectations for their production at the Tevatron. As a final topic, he touches upon some of the consequences that result from having the Fermi scale arise from an underlying theory. Some aspects of the composite Higgs model and of the strongly coupled standard model are briefly reviewed

Paul, Simone; Smith, Peter K; Blumberg, Herbert H

2012-11-01

In the UK schools are required by law to protect students from bullying; the responsibility of teachers to govern such behaviour has been extended outside the school setting to include cyberbullying. In this investigation, cyberbullying in secondary education is explored from the student perspective using a qualitative method of enquiry. Reported awareness and understanding about the legal aspects of cyberbullying are investigated; consideration is given to legislation, cybercrime, children's rights, school sanctions and safeguarding responsibilities. A total of 197 male and female students aged between 11 and 14 years old participated. Despite the availability of information on guidelines and legislation at national, local, and school level, this does not appear to have reached ground level of the individual student. There is a considerable gap between what students should know and what they report to be aware of with regard to legal aspects of cyberbullying. To address concerns of keeping up with the pace of change in cyberbullying, a collaborative approach is required with young people and adults sharing expertise.

The paper presents a review of the main thermophysical aspects of NPPs safety and efficiency increase applied to WWERs. Improvement of operating WWER units is the main short-term and medium-term tasks of the utilities in Ukraine. The new generation of reactors for increasing the reactor facilities efficiency should utilize achievements of thermo physics research results. The thermophysical aspects of NPPs safety and efficiency are envisaged in the context of the atomic energy development strategy. The analysis of thermophysical processes occurring in the core shows that a number of problems concerning boiling crisis and heat exchange intensification during transient and accidents are not solved in spite of numerous calculations and experimental research. The up-to-date safety conception includes severe accidents consideration for safety assessment. Review of severe accidents management is presented. Additional validation of the West advanced thermal hydraulic codes which are applied for WWERs reassessment calculations is required. Contribution of the processes which might occur in WWER containment to safety problems solving is considered as well. (author)

In situ leaching of uranium: Technical, environmental and economic aspects

International Nuclear Information System (INIS)

1989-01-01

Within the framework of its activities in nuclear raw materials the International Atomic Energy Agency has convened a series of meetings to discuss various aspects of uranium ore processing technology, recovery of uranium from non-conventional resources and development of projects for the production of uranium concentrates including economic aspects. As part of this continuing effort to discuss and document important aspects of uranium production the IAEA convened a Technical Committee Meeting on Technical, Economic and Environmental Aspects of In-Situ Leaching. Although the use of this technique is limited by geological and economic constraints, it has a significant potential to produce uranium at competitive prices. This is especially important in the current uranium market which is mainly characterised by large inventories, excess production capability and low prices. This situation is not expected to last indefinitely but it is unlikely to change drastically in the next ten years or so. This Technical Committee Meeting was held in Vienna from 3 to 6 November 1987 with the attendance of 24 participants from 12 countries. Eight papers were presented. Technical sessions covered in-situ mining research, environmental and licensing aspects and restoration of leached orebodies; the technological status of in-situ leaching, the current status and future prospects of in-situ leaching of uranium in Member States, general aspects of planning and implementation of in-situ projects and the economics of in-situ leaching.

Full Text Available Grammatical aspect is known to shape event understanding. However, little is known about how it interacts with other important temporal information, such as recent and distant past. The current work uses computer-mouse tracking (Spivey, Grosjean, & Knoblich, 2005 to explore the interaction of aspect and temporal context. Participants in our experiment listened to past motion event descriptions that varied according to aspect (simple past, past progressive and temporal distance (recent past, distant past while viewing scenes with paths and implied destinations. Participants used a computer mouse to place characters into the scene to match event descriptions. Our results indicated that aspect and temporal context interact in interesting ways. When aspect placed emphasis on the ongoing details of the event and the temporal context was recent (thus, making fine details available in memory, this match between conditions elicited smoother and faster computer mouse movements than when conditions mismatched. Likewise, when aspect placed emphasis on the less-detailed end state of the event and temporal context was in the distant past (thus making fine details less available, this match between conditions also elicited smoother and faster computer mouse movements.

Energy and social aspects

International Nuclear Information System (INIS)

Perez, D.; Gomez, Y.

2008-01-01

In this section, the social aspects of Cuba's energy system are described, based on the accessibility and availability of energy services and the affordability and acceptance of these energy services by the population. Accessibility refers to the existence of modern energy services and supporting infrastructures that allow the population, regardless of income level, place of residence, race, religion, etc., the use of modern fuels. Logistics and the economy determine the amount and kinds of energy and energy services available in each place. Even if energy services are accessible to the population, problems with their availability during particular time periods may exist; thus, this section discusses the problems of availability of modern fuels in Cuba. Affordability relates to the ability of the population to pay for the energy services that are accessible and available. Energy prices should be low enough (without affecting the profitability of the producing companies) to enable everyone's minimum requirements for modern energy services to be satisfied. Acceptability concerns the social and/or environmental problems related to energy chains, ranging from production and use to the disposal of waste generated by energy production. Making an assessment of the acceptability of an energy option is often difficult and sometimes involves many issues, including social, environmental, cultural, economic and religious aspects at local and regional levels

Diabetic patients: Psychological aspects.

Adili, Fatemeh; Larijani, Bagher; Haghighatpanah, Mohammadreza

2006-11-01

This study was undertaken to consider the psychological aspect of diabetes with regard to improving clinical outcomes. The review was limited to literature reports on the causes, solutions, and treatments of some common psychological problems known to complicate diabetes management. A literature search was undertaken using Pub-Med, CINAHL, Proquest, Elsevier, Blackwell Synergy, Ovid, Ebsco, Rose net, and Google websites, including studies published in English journals between 1995 and 2006. Therefore about 88 articles were selected based on the inclusion criteria. In earlier studies, relatively little empirical research was found to substantiate the effect of psychological counseling in complicated diabetes. The greatest deficits were seen in areas of mental health, self-esteem parent impact, and family cohesion. There were some different factors, which influence the psychological aspect of diabetic patients, such as age, gender, place of living, familial and social support, motivation, energy, life satisfaction, and lifestyle. There are various types of solutions for coping with the psychological problems in diabetic clients. The most essential solution lies in educating the patients and healthcare providers on the subject. Before initiating each educational intervention, a thorough assessment would be crucial. Treatment plans may benefit from cognitive behavior therapy (CBT), behavior family therapy, improving family communication, problem-solving skills, and providing motivation for diabetic patients. Moreover, it seems that the close collaboration between diabetologists and psychologists would be fruitful.

Weisberg, Yanna J; Deyoung, Colin G; Hirsh, Jacob B

2011-01-01

This paper investigates gender differences in personality traits, both at the level of the Big Five and at the sublevel of two aspects within each Big Five domain. Replicating previous findings, women reported higher Big Five Extraversion, Agreeableness, and Neuroticism scores than men. However, more extensive gender differences were found at the level of the aspects, with significant gender differences appearing in both aspects of every Big Five trait. For Extraversion, Openness, and Conscientiousness, the gender differences were found to diverge at the aspect level, rendering them either small or undetectable at the Big Five level. These findings clarify the nature of gender differences in personality and highlight the utility of measuring personality at the aspect level.

Designing for the handicapped persons, aiming at the liquidation of the barriers is actually an essential part of the architects activity. It results from the fact that the handicapped persons issue became the interdisciplinary one. The architect, being responsible for the living space and environment creation, is to design the friendly environment for the handicapped persons. The space favourable for the handicapped is favourable for all. There are many aspects of the designing for the handicapped; legislative or execution issues are the examples. The legislative aspect is presented in this paper on the base of the contemporary legal rules of the Polish Republic, whereas the execution aspect is introduced and discussed on the basis of the two projects designed by the Design Bureau in Cracow and being currently in realization. These are: housing & service unit (Boruty-Spiechowicza Str., Cracow) and the Faculty of Philosophy complex at the Jesuits College (Kopernika Str., Cracow).

2003-05-01

Full Text Available This research analyzes the issue from the jurisprudential and social aspects. The social aspect focuses on the existing viewpoints regarding the grounds for addiction and also looks into the jurisprudential decrees by Shiite and Sunni jurisprudents regarding opium, hashish and tobacco. In other words, the research focuses on the impacts of jurisprudential decrees on social issues and vice-versa. The research in order to offer strong proof for subjects under discussion conducts documental studies and extracts jurisprudential, historical and scientific texts. In all, this research promotes one’s knowledge about the chronology of drugs including opiates, hashish and tobacco, their side effects, reasons behind drug addiction and jurisprudential decrees in this regard from the viewpoint of jurisprudents. From the viewpoint of social philosophy it raises the thought that there is a dialectic relationship between the thought and the environment and necessitates the need for changes in jurisprudential thoughts. As far as is applied aspect is concerned, it offers solutions for preventing drug addiction.

Full Text Available Research has shown that character strengths are positively linked with well-being in general. However, there has not been a fine-grained analysis up to date. This study examines the individual relational aspects between the 24 character strengths, subjective well-being (SWB, and different aspects of psychological well-being (PWB at two times of measurement (N = 117. Results showed that overall the “good character” was significantly stronger related with PWB than with SWB. The character strength “hope” was at least moderately correlated with the PWB aspects meaning, optimism and autonomy, and “zest” with the PWB aspects relationships and engagement. “Persistence” showed the highest correlation with the PWB aspect mastery. Out of the 24 character strengths, the happiness-related strengths (hope, zest, gratitude, curiosity, and love were more likely to correlate with PWB and SWB than any other character strength. This study offers a more fine-grained and thorough understanding of specific relational aspects between the 24 character strengths and a broad range of well-being aspects. Future studies should take up a detailed strategy when exploring relationships between character strengths and well-being.

Rectenna session: Micro aspects

Gutmann, R. J.

1980-01-01

Two micro aspects of rectenna design are discussed: evaluation of the degradation in net rectenna RF to DC conversion efficiency due to power density variations across the rectenna (power combining analysis) and design of Yagi-Uda receiving elements to reduce rectenna cost by decreasing the number of conversion circuits (directional receiving elements). The first of these involves resolving a fundamental question of efficiency potential with a rectenna, while the second involves a design modification with a large potential cost saving.

Directory of Open Access Journals (Sweden)

Yara Fleury Molen

2014-01-01

Full Text Available Insomnia involves difficulty in falling asleep, maintaining sleep or having refreshing sleep. This review gathers the existing informations seeking to explain insomnia, including those that focus on psychological aspects and those considered neurobiological. Insomnia has been defined in psychological (cognitive components, such as worries and rumination, and behavioral aspects, such as classic conditioning and physiological terms (increased metabolic rate, with increased muscle tone, heart rate and temperature. From the neurobiological point of view, there are two perspectives: one which proposes that insomnia occurs in association with a failure to inhibit wakefulness and another that considers hyperarousal as having an important role in the physiology of sleep. The non-pharmacological interventions developed to face different aspects of insomnia are presented.

Aspect-related Vegetation Differences Amplify Soil Moisture Variability in Semiarid Landscapes

Science.gov (United States)

Yetemen, O.; Srivastava, A.; Kumari, N.; Saco, P. M.

2017-12-01

Soil moisture variability (SMV) in semiarid landscapes is affected by vegetation, soil texture, climate, aspect, and topography. The heterogeneity in vegetation cover that results from the effects of microclimate, terrain attributes (slope gradient, aspect, drainage area etc.), soil properties, and spatial variability in precipitation have been reported to act as the dominant factors modulating SMV in semiarid ecosystems. However, the role of hillslope aspect in SMV, though reported in many field studies, has not received the same degree of attention probably due to the lack of extensive large datasets. Numerical simulations can then be used to elucidate the contribution of aspect-driven vegetation patterns to this variability. In this work, we perform a sensitivity analysis to study on variables driving SMV using the CHILD landscape evolution model equipped with a spatially-distributed solar-radiation component that couples vegetation dynamics and surface hydrology. To explore how aspect-driven vegetation heterogeneity contributes to the SMV, CHILD was run using a range of parameters selected to reflect different scenarios (from uniform to heterogeneous vegetation cover). Throughout the simulations, the spatial distribution of soil moisture and vegetation cover are computed to estimate the corresponding coefficients of variation. Under the uniform spatial precipitation forcing and uniform soil properties, the factors affecting the spatial distribution of solar insolation are found to play a key role in the SMV through the emergence of aspect-driven vegetation patterns. Hence, factors such as catchment gradient, aspect, and latitude, define water stress and vegetation growth, and in turn affect the available soil moisture content. Interestingly, changes in soil properties (porosity, root depth, and pore-size distribution) over the domain are not as effective as the other factors. These findings show that the factors associated to aspect-related vegetation

Tenses, Aspects, and Categories of Evidentiality and Egocentricity in Spoken Lhasa Tibetan

Directory of Open Access Journals (Sweden)

Jiang Di

2007-10-01

Full Text Available This paper mainly discusses verbal aspects and their syntactic markers in Lhasa Tibetan. Since aspects in Tibetan always share markers with other important categories called evidentiality and egocentricity, the former of which assesses the evidence of speaker's statement and the latter denotes behavioral characteristics of a speaker's ego-centricity, this paper simultaneously describes all three types: aspect, evidentiality and egocentricity. There are nine types of verb aspects in Lhasa Tibetan, namely: Prospective, Imminent, Premediated, Realis, Durative, Resultative, Merely-past, Perfect, and Contextual aspects. There are four types of evidentialities, namely, Self-knowledge, Knowing-by-sight, Knowing-by-newly-found-information and Knowing-by-inference evidentialities. Categories of egocentricity demonstrate whether an action is towards the Self or the Other, whether the speaker gains or loses, and so on. Additionally，this essay also discusses the interactive relationship between syntactical verb aspects and personal pronouns, intentionality, modality, as well as temporal-spatial cognition.

Bam earthquake was the most catastrophic natural disasters in recent years. The aim of this study was to review different aspects of crisis management during and after the catastrophic earthquake in Bam City, Iran. Data needed for this systematic review were collected through searching PubMed, EMBASE and SID databases, for the period from 2003 to 2011. Keywords included earthquake, Iran and Bam earthquake. The data were summarized and were analyzed using Content Analysis. Out of 422 articles, 25 articles were included in the study. Crisis Management aspects and existing pitfalls were classified into seven categories including planning and organization, human resource management, management of logistics, international humanitarian aids, field performance of the military and security forces, health and medical service provision, and information management. Positive aspects and major pitfalls of crisis management have been introduced in all the mentioned categories. The available evidence indicated poor crisis management during Bam earthquake that resulted in aggravating the losses as well as diminishing the effect of interventions. Thus, concerning the importance of different aspects of the crisis management and the high prevalence of disasters in Iran, the observed vulnerability in disaster management process should be addressed.

Linguistic aspects of writing for professional purposes

2016-03-01

Full Text Available Writing for Professional Purposes is considered as a means of communication between professionals who belong to two communities that have different languages, but share the same knowledge or expertise. The article gives a hint on how writing for specific purposes evolved to give rise to the creation of Writing for Professional Purposes. The social, cultural and cognitive aspects are an essential part of Writing for Professional Purposes since the physical act of writing cannot be considered only a result or product of the knowledge the individual possesses but also a social and cultural act. Therefore, the social and cultural aspects of writing explains the specificities and the intricacies of the effects these aspects have on writing for it is considered as an inseparable part of social and cultural groups. On the other hand, the cognitive aspect of writing explains and emphasizes the mental activities of the individual during the decision-making process while he/she is writing planning and editing their material having in mind the audience. On the same line of reasoning, writing for professional purposes in a second language means that the writer has to consider the audience twice; first, there is an audience who shares the same knowledge or expertise and second, the audience does not have the same language. Consequently, writing in another language that is not the first language with a specific jargon as well as a specific grammatical structure brings about a lot of difficulties. Hence, writing in professional contexts in the mother tongue implies only writing in a specialized version of a language already known to the writer, but writing in a target language means that the writer has to learn the target language and the specialized version of that language.

2016-01-01

In wastewater treatment facilities (WWTF), technical and financial aspects have been considered a priority, while other issues, such as social aspects, have not been evaluated seriously and there is not an accepted methodology for assessing it. In this work, a methodology focused on social concerns related to WWTF is presented. The methodology proposes the use of 25 indicators as a framework for measuring social performance to evaluate the progress in moving towards sustainability. The methodology was applied to test its applicability and effectiveness in two WWTF in Mexico (urban and rural). This evaluation helped define the key elements, stakeholders and barriers in the facilities. In this context, the urban facility showed a better overall performance, a result that may be explained mainly by the better socioeconomic context of the urban municipality. Finally, the evaluation of social aspects using the semi-qualitative approach proposed in this work allows for a comparison between different facilities and for the identification of strengths and weakness, and it provides an alternative tool for achieving and improving wastewater management. - Highlights: • The methodology proposes 25 indicators as a framework for measuring social performance in wastewater treatment facilities. • The evaluation helped to define the key elements, stakeholders and barriers in the wastewater treatment facilities. • The evaluation of social aspects allows the identification of strengths and weakness for improving wastewater management. • It provides a social profile of the facility that highlights the best and worst performances.

Nouzil, Ibrahim; Raza, Ali; Pervaiz, Salman

2017-09-01

Sustainable development has been recognized globally as one of the major driving forces towards the current technological innovations. To achieve sustainable development and attain its associated goals, it is very important to properly address its concerns in different aspects of technological innovations. Several industrial sectors have enjoyed productivity and economic gains due to advent of automation technology. It is important to characterize sustainability for the automation technology. Sustainability is key factor that will determine the future of our neighbours in time and it must be tightly wrapped around the double-edged sword of technology. In this study, different impacts of automation have been addressed using the ‘Circles of Sustainability’ approach as a framework, covering economic, political, cultural and ecological aspects and their implications. A systematic literature review of automation technology from its inception is outlined and plotted against its many outcomes covering a broad spectrum. The study is more focused towards the social aspects of the automation technology. The study also reviews literature to analyse the employment deficiency as one end of the social impact spectrum. On the other end of the spectrum, benefits to society through technological advancements, such as the Internet of Things (IoT) coupled with automation are presented.

This chapter of the report of the 'Flavour in the era of LHC' workshop discusses flavor related issues in the production and decays of heavy states at LHC, both from the experimental side and from the theoretical side. We review top quark physics and discuss flavor aspects of several extensions of the Standard Model, such as supersymmetry, little Higgs model or models with extra dimensions. This includes discovery aspects as well as measurement of several properties of these heavy states. We also present public available computational tools related to this topic.

Stability of high β large aspect ratio tokamaks

International Nuclear Information System (INIS)

Cowley, S.C.

1991-10-01

High β(β much-gt ε/q 2 ) large aspect ratio (ε much-gt 1) tokamak equilibria are shown to be always stable to ideal M.H.D. modes that are localized about a flux surface. Both the ballooning and interchange modes are shown to be stable. This work uses the analytic high β large aspect ratio tokamak equilibria developed by Cowley et.al., which are valid for arbitrary pressure and safety factor profiles. The stability results make no assumption about these profiles or the shape of the boundary. 14 refs., 4 figs

Some aspects of nuclear fuel economics

International Nuclear Information System (INIS)

Timm, M.

1975-01-01

The paper reviews the economic aspects of nuclear fuel based on the year 1975. The focus of attention is on the well-established light-water reactors, which for the time being, and also for the foreseeable future, account for the bulk of the world's nuclear power capacity. The author describes the principal economic aspects of the light-water fuel cycle components and discusses their future development to the extent that this can be foreseen. Various approaches to the formulation of the contract for the supply of light-water fuel are discussed on the basis of the established procedure. After some introductory comments on methods of calculating specific fuel costs, the author describes the main results of fuel cycle calculations. The economic aspects of nuclear fuel for other types of reactors are discussed in the sequence in which it is planned to introduce such reactors commercially. The economic data available apply to reactors ranging from the heavy-water-moderated type, through helium-cooled high-temperature reactors, to the fast breeders, and are based more and more on results of feasibility studies and less on practical operational experience. For this reason the author discusses only the basic data of importance, as viewed from the present-day stand-point, and mentions the emerging trends. It should be pointed out, however, that a comprehensive description of this kind can only show the situation at a given moment. Numerous political, economic and technological influences are in a state of permanent flux, hence economic data and developments may easily change within a short time. (author)

Nutritional Aspects of Dysphagia Management.

Science.gov (United States)

Gallegos, C; Brito-de la Fuente, E; Clavé, P; Costa, A; Assegehegn, G

This chapter describes the nutritional aspects of dysphagia management by starting with the definition of these two conditions (dysphagia and malnutrition) that share three main clinical characteristics: (a) their prevalence is very high, (b) they can lead to severe complications, and (c) they are frequently underrecognized and neglected conditions. From an anatomical standpoint, dysphagia can result from oropharyngeal and/or esophageal causes; from a pathophysiological perspective, dysphagia can be caused by organic or structural diseases (either benign or malignant) or diseases causing impaired physiology (mainly motility and/or perception disorders). This chapter gathers up-to-date information on the screening and diagnosis of oropharyngeal dysphagia, the consequences of dysphagia (aspiration pneumonia, malnutrition, and dehydration), and on the nutritional management of dysphagic patients. Concerning this last topic, this chapter reviews the rheological aspects of swallowing and dysphagia (including shear and elongational flows) and its influence on the characteristics of the enteral nutrition for dysphagia management (solid/semisolid foods and thickened liquids; ready-to-use oral nutritional supplements and thickening powders), with special focus on the real characteristics of the bolus after mixing with human saliva. © 2017 Elsevier Inc.

Automated Quantification of Stroke Damage on Brain Computed Tomography Scans: e-ASPECTS

Directory of Open Access Journals (Sweden)

James Hampton-Till

2015-08-01

Full Text Available Emergency radiological diagnosis of acute ischaemic stroke requires the accurate detection and appropriate interpretation of relevant imaging findings. Non-contrast computed tomography (CT provides fast and low-cost assessment of the early signs of ischaemia and is the most widely used diagnostic modality for acute stroke. The Alberta Stroke Program Early CT Score (ASPECTS is a quantitative and clinically validated method to measure the extent of ischaemic signs on brain CT scans. The CE-marked electronic-ASPECTS (e-ASPECTS software automates the ASPECTS score. Anglia Ruskin Clinical Trials Unit (ARCTU independently carried out a clinical investigation of the e-ASPECTS software, an automated scoring system which can be integrated into the diagnostic pathway of an acute ischaemic stroke patient, thereby assisting the physician with expert interpretation of the brain CT scan. Here we describe a literature review of the clinical importance of reliable assessment of early ischaemic signs on plain CT scans, and of technologies automating these processed scoring systems in ischaemic stroke on CT scans focusing on the e-ASPECTS software. To be suitable for critical appraisal in this evaluation, the published studies needed a sample size of a minimum of 10 cases. All randomised studies were screened and data deemed relevant to demonstration of performance of ASPECTS were appraised. The literature review focused on three domains: i interpretation of brain CT scans of stroke patients, ii the application of the ASPECTS score in ischaemic stroke, and iii automation of brain CT analysis. Finally, the appraised references are discussed in the context of the clinical impact of e-ASPECTS and the expected performance, which will be independently evaluated by a non-inferiority study conducted by the ARCTU.

Understanding the influence of aspect ratio on water immersion into silica nanoholes is of significant importance to the etching process of semiconductor fabrication and other water immersion-related physical and biological processes. In this work, the processes of water immersion into silica nanoholes with different height/width aspect ratios (ϕ = 0.87, 1.92, 2.97, 4.01, 5.06) and different numbers of water molecules (N = 9986, 19972, 29958, 39944) were studied by molecular dynamics simulations. A comprehensive analysis has been conducted about the detailed process of water immersion and the influence of aspect ratios on water immersion rates. Five distinguishable stages were identified for the immersion process with all studied models. The results reveal that water can easily immerse into the silica nanoholes with larger ϕ and smaller N. The calculation also suggests that aspect ratios have a greater effect on water immersion rates for larger N numbers. The mechanism of the water immersion process is discussed in this work. We also propose a mathematical model to correlate the complete water immersion process for different aspect ratios.

2012-01-01

Hauptbeschreibung Aspect-oriented-programming is a relatively new technique that has evolved on top of the already well-established approach of object-oriented programming. When it is used correctly, it promises to remove many redundant parts of a code that appear repeatedly in an application, essentially untangling the original code. Thus, it can lead to a cleaner, more separated software design, to greater modularity and maintainability. Time-savings in software engineering can also be huge cost-savings, and anything that increases software quality is a welcome sight in an industr

Relationship between BaTiO₃ nanowire aspect ratio and the dielectric permittivity of nanocomposites.

Science.gov (United States)

Tang, Haixiong; Zhou, Zhi; Sodano, Henry A

2014-04-23

The aspect ratio of barium titanate (BaTiO3) nanowires is demonstrated to be successfully controlled by adjusting the temperature of the hydrothermal growth from 150 to 240 °C, corresponding to aspect ratios from 9.3 to 45.8, respectively. Polyvinylidene fluoride (PVDF) nanocomposites are formed from the various aspect ratio nanowires and the relationship between the dielectric constant of the nanocomposite and the aspect ratio of the fillers is quantified. It was found that the dielectric constant of the nanocomposite increases with the aspect ratio of the nanowires. Nanocomposites with 30 vol % BaTiO3 nanowires and an aspect ratio of 45.8 can reach a dielectric constant of 44.3, which is 30.7% higher than samples with an aspect ratio of 9.3 and 352% larger than the polymer matrix. These results demonstrate that using high-aspect-ratio nanowires is an effective way to control and improve the dielectric performance of nanocomposites for future capacitor applications.

In this paper, we discuss some design aspects of transuranic field studies. Some of the principal steps in the design of such studies are given and illustrated using examples. This is followed by a review of sampling designs that have been used at nuclear detonation and safety-shot sites on the Nevada Test Site and elsewhere for estimating spatial pattern and total amounts in soil. Some design aspects of ecosystem-type transuranic studies for estimating total amounts as well as movement of transuranics between ecosystem components are also discussed. Acceptance sampling using either attributes or measurements is considered as a possible approach for deciding whether to clean up a contaminated site. Three general guidelines for the design of efficient transuranic studies are presented

This study was designed to explore two aspects (mother-father; woman-man) of Masculinity-Femininity in personality. Sixty-five middle school students, 150 high school students and 219 university students were asked to rate the desirability for them, their fathers and mothers, and society of each of 45 items comprising a questionnaire which described valid characteristics of these two aspects. Analysis of the results revealed that male subjects in all age groups seemed to feel that their fathers desired them to be more masculine (i.e., father and man) than they, themselves, desired. Those of high school and university age also seemed to feel that their mothers and fathers and society desired more motherliness of them than they, themselves, desired. Female high school and university subjects seemed to feel that their fathers and mothers desired much more femininity (mother and woman) and much less masculinity (father and man) than they, themselves, desired.

We describe the intricacies of instrumentation of the Java class library and present an extended instrumentation approach allowing the user to choose between a pure Java weaving solution based on a two-phases instrumentation scheme, or a single-phase one requiring a tiny native code layer. The single-phase approach allows to better isolate the weaving process from the execution of the woven code.

Effect of aspect ratio in free-swimming plunging flexible plates

Science.gov (United States)

Yeh, Peter; Alexeev, Alexander

2015-11-01

Using three dimensional fully-coupled fluid-structure interaction simulations, we investigate the free swimming of plunging elastic rectangular plates with aspect ratios ranging from 0.5 to 5 in a viscous fluid with Reynolds number 250. We find that maximum velocity occurs near the first natural frequency regardless of aspect ratio, while the maximum swimming economy occurs away from the first natural frequency and corresponds to a specific swimmer bending pattern characterized by reduced displacement of the swimmer's center of mass. Furthermore, we find that swimmers with wider span are both faster and more economical than narrow swimmers. These faster speeds are due to decreased drag for low aspect ratio plunging swimmers, which is in agreement with a recently proposed vortex-induced drag model that suggests that the smaller relative size of side vortices in low aspect ratio swimmers creates less drag per unit width. Our results are useful for the design of small autonomous micro-swimming devices and also provide insights on the physics of aquatic locomotion using oscillating fins.

Cereals and, most specifically, wheat are described in this chapter highlighting on their safety and quality aspects. Moreover, wheat quality aspects are adequately addressed since they are used to characterize dough properties and baking quality. Determination of dough properties is also mentioned and pasta quality is also described in this chapter. Chemometrics-multivariate analysis is one of the analyses carried out. Regarding production weighing/mixing of flours, kneading, extruded wheat flours, and sodium chloride are important processing steps/raw materials used in the manufacturing of pastry products. Staling of cereal-based products is also taken into account. Finally, safety aspects of cereal-based products are well documented with special emphasis on mycotoxins, acrylamide, and near infrared methodology.

Aspect-Aided Dynamic Non-Negative Sparse Representation-Based Microwave Image Classification

Directory of Open Access Journals (Sweden)

Xinzheng Zhang

2016-09-01

Full Text Available Classification of target microwave images is an important application in much areas such as security, surveillance, etc. With respect to the task of microwave image classification, a recognition algorithm based on aspect-aided dynamic non-negative least square (ADNNLS sparse representation is proposed. Firstly, an aspect sector is determined, the center of which is the estimated aspect angle of the testing sample. The training samples in the aspect sector are divided into active atoms and inactive atoms by smooth self-representative learning. Secondly, for each testing sample, the corresponding active atoms are selected dynamically, thereby establishing dynamic dictionary. Thirdly, the testing sample is represented with ℓ 1 -regularized non-negative sparse representation under the corresponding dynamic dictionary. Finally, the class label of the testing sample is identified by use of the minimum reconstruction error. Verification of the proposed algorithm was conducted using the Moving and Stationary Target Acquisition and Recognition (MSTAR database which was acquired by synthetic aperture radar. Experiment results validated that the proposed approach was able to capture the local aspect characteristics of microwave images effectively, thereby improving the classification performance.

Full Text Available The trusts have been frequently used in the countries which function under the Anglo-Saxon law system, but it most certainly represents an innovation in the new Romanian legislation. For this reason, in this paper, we tried to highlight the main differences between the trust regulated in the Romanian Civil code and its corespondent in other legal systems. Observing that the trust in an institution that is mainly theoretical, and the reluctance of practicioners in using it, we tried to analyze the trust, regarding its practical side. In this paper, we will take into consideration the following aspects: the rights that the trustee acquires after establishing the trust, that will be explained through the new regulations regarding the division of assets, the quality of the parties and the limits in which the trustee may be held liable. Other important aspects are: the means that the new regulations provide in order to protect the interests of the creditors and at the same time, the fiduciary assets; the formalities which the law requires and the means of termination of the contract. In the end, in order to identify alternative solutions, we will compare the trust (regulated in the Civil code with the management of assets that belong to a third party.

Full Text Available Throughout the paper, we have highlighted some controversial aspects regarding the crime of tax evasion, referring to some important decisions of the High Court of Cassation and Justice and also of the Bucharest Court of Appeal. Debating upon the impunity provision stated by art. 10 of Law no. 241/2005, the study also sheds light upon the issue of the perspective of the judicial organs regarding the juridical regime of the tax due for dividends. The main focus of the paper leads to the situations when there is legal ground for the tax due for dividends to be considered part of the damage caused by tax evasion crime. The study includes a short analysis of some relevant provisions of the Romanian Fiscal Code and also some aspects deriving from decisions issued by the Administrative and Tax Litigation Chamber of The High Court of Cassation and Justice concerning the legal regime of dividends. Consequently, the authors are presenting both perspectives of the interpretation of the issue regarding the tax due for dividends to be considered part of the damage caused by tax evasion crime, resulting from two decisions of the two Criminal Sections of The Bucharest Court of Appeal, also arguing in favour of the most solid interpretation among them

Nonlinear viscoplasticity in ASPECT: benchmarking and applications to subduction

Science.gov (United States)

Glerum, Anne; Thieulot, Cedric; Fraters, Menno; Blom, Constantijn; Spakman, Wim

2018-03-01

ASPECT (Advanced Solver for Problems in Earth's ConvecTion) is a massively parallel finite element code originally designed for modeling thermal convection in the mantle with a Newtonian rheology. The code is characterized by modern numerical methods, high-performance parallelism and extensibility. This last characteristic is illustrated in this work: we have extended the use of ASPECT from global thermal convection modeling to upper-mantle-scale applications of subduction.Subduction modeling generally requires the tracking of multiple materials with different properties and with nonlinear viscous and viscoplastic rheologies. To this end, we implemented a frictional plasticity criterion that is combined with a viscous diffusion and dislocation creep rheology. Because ASPECT uses compositional fields to represent different materials, all material parameters are made dependent on a user-specified number of fields.The goal of this paper is primarily to describe and verify our implementations of complex, multi-material rheology by reproducing the results of four well-known two-dimensional benchmarks: the indentor benchmark, the brick experiment, the sandbox experiment and the slab detachment benchmark. Furthermore, we aim to provide hands-on examples for prospective users by demonstrating the use of multi-material viscoplasticity with three-dimensional, thermomechanical models of oceanic subduction, putting ASPECT on the map as a community code for high-resolution, nonlinear rheology subduction modeling.

The increase of bundle supply has become widespread in several sectors (for instance in telecommunications and energy fields). This paper review relates strategic aspects of bundling. The main purpose of this paper is to analyze profitability of bundling strategies according to the degree of competition and the characteristics of goods. Moreover, bundling can be used as price discrimination tool, screening device or entry barriers. In monopoly case bundling strategy is efficient to sort consumers in different categories in order to capture a maximum of surplus. However, when competition increases, the profitability on bundling strategies depends on correlation of consumers' reservations values. (author)

Carbon nanotubes (CNTs) have specific physico-chemical and electrical properties that are useful for telecommunications, medicine, materials, manufacturing processes and the environmental and energy sectors. Yet, despite their many advantages, it is also important to determine whether CNTs may represent a hazard to the environment and human health. Like asbestos, the aspect ratio (length:diameter) and metal components of CNTs are known to have an effect on the toxicity of carbon nanotubes. Thus, to evaluate the toxic potential of CNTs in relation to their aspect ratio and metal contamination, in vivo and in vitro genotoxicity tests were conducted using high-aspect-ratio (diameter: 10-15 nm, length: ~10 μm) and low-aspect-ratio multi-wall carbon nanotubes (MWCNTs, diameter: 10-15 nm, length: ~150 nm) according to OECD test guidelines 471 (bacterial reverse mutation test), 473 (in vitro chromosome aberration test), and 474 (in vivo micronuclei test) with a good laboratory practice system. To determine the treatment concentration for all the tests, a solubility and dispersive test was performed, and a 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) solution found to be more suitable than distilled water. Neither the high- nor the low-aspect-ratio MWCNTs induced any genotoxicity in a bacterial reverse mutation test (~1,000 μg/plate), in vitro chromosome aberration test (without S9: ~6.25 μg/ml, with S9: ~50 μg/ml), or in vivo micronuclei test (~50 mg/kg). However, the high-aspect-ratio MWCNTs were found to be more toxic than the low-aspect-ratio MWCNTs. Thus, while high-aspect-ratio MWCNTs do not induce direct genotoxicity or metabolic activation-mediated genotoxicity, genotoxicity could still be induced indirectly through oxidative stress or inflammation.

MACROECONOMIC ASPECTS OF COMPETITIVENESS

Full Text Available In the process of globalization of world economic processes, the role of individual national economies increases, comparative advantages of the development of a country are formed, and their competitiveness is ensured. That is why it is worth emphasizing the importance of increasing the competitiveness of each individual country, based on its internal capacity. In a broad aspect, the competitiveness of the national economy is perceived as the ability of the country to ensure the balance of its external proportions and to avoid those constraints imposed by the foreign economic sphere, to self-organizing the improvement of their world economic ties. The competitiveness of the economy at the macro level is associated with the duration of the cycle of reproduction of the main productive assets and, accordingly, the jobs, productive forces of society and determined by the overall economic efficiency of investment. The criteria of competitiveness of the national economy are the growth of social productivity of labor, increase of social and economic efficiency of production and standard of living of the population. The competitiveness of the national economy determines sustainable socio-economic development of the country, as well as sustainable development predetermines the competitiveness of not only the country, but also all its levels. Scientific results are obtained using special methods of research of economic objects and phenomena, that is, based on the correlation and regressive, comparative analysis (establishing the relationship between the indicator factor, as well as economic modeling. Findings. Generalizing analysis and the importance of the macroeconomic aspect of competitiveness were used in the research paper, which will allow to better respond to the economic situation, in accordance with the trends of the “green” transformation of the economy; which in turn will solve important problems of the development and implementation of its

Thedeen, T.

1997-01-01

Beside the technical problems of ADTT which remain to be solved it is crucial for the ADTT progress that safety and economical aspects are considered already during the research and planning phases. Safety here stands for the converse of risk, negative consequences for human life and health and the environment together with the corresponding probabilities. The system to be considered includes all phases of an ADTT plant, a life cycle analysis (LCA). The risk analysis is useful for two purposes: comparison with other ways of handling nuclear waste, e.g. geological repository and for valuation of different construction designs. Due to lack of precise plans and adequate data the analysis will be more of a qualitative than quantitative type. The main risks appear in connection with repair and replacement work. 2 refs., 1 fig

Some probabilistic aspects of fracture in structural and mechanical components are examined. The principles of fracture mechanics, material quality and inspection uncertainty are formulated into a conceptual and analytical framework for prediction of failure probability. The role of probabilistic fracture mechanics in a more global context of risk and optimization of decisions is illustrated. An example, where Monte Carlo simulation was used to implement a probabilistic fracture mechanics analysis, is discussed. (orig.)

Oscillatory convection in low aspect ratio Czochralski melts

Anselmo, A.; Prasad, V.; Koziol, J.; Gupta, K. P.

1993-11-01

Modeling of the crucible in bulk crystal growth simulations as a right circular cylinder may be adequate for high aspect ratio melts but this may be unrealistic when the melt height is low. Low melt height is a unique feature of a solid feed continuous Czochralski growth process for silicon single crystals currently under investigation. At low melt heights, the crucible bottom curvature has a dampening effect on the buoyancy-induced oscillations, a source of inhomogeneities in the grown crystal. The numerical results demonstrate how the mode of convection changes from vertical wall-dominated recirculating flows to Benard convection as the aspect ratio is lowered. This phenomenon is strongly dependent on the boundary condition at the free surface of the melt, which has been generally considered to be either adiabatic or radiatively cooled. A comparison of the flow oscillations in crucibles with and without curved bottoms at aspect ratios in the range of 0.25 to 0.50, and at realistic Grashof numbers (10 7 < Gr < 10 8) illustrate that changing the shape of the crucible may be an effective means of suppressing oscillations and controlling the melt flow.

Generating language that reflects the temporal organization of represented knowledge requires a language generation model that integrates contemporary theories of tense and aspect, temporal representations, and methods to plan text. This paper presents a model that produces complex sentences that reflect temporal relations present in underlying temporal concepts. The main result of this work is the successful application of constrained linguistic theories of tense and aspect to a generator which produces meaningful event combinations and selects appropriate connecting words that relate them.

1999-07-01

Full Text Available Microstructural aspects of polycrystalline copper sheets subjected to complex strain paths were analysed in this work. Dislocation structures developed during the strain paths (rolling and tension and the evolution of this microstructure during reloading have been studied. The active slip systems developed in each strain path were used to explain the microstructural evolution. The heterogeneous surface deformation observed on polished tensile specimens prestrained in rolling was also analysed. The structural aspects are related with the mechanical behaviour of the material, namely with the increase in yield stress in reloading, the work hardening evolution and the premature occurrence of plastic instability for some prestrain values.

2011-01-01

This article examines distinctive aspects of medical care experienced by a 55-year-old hospitalized for quintuple coronary artery bypass surgery who was also a senior physician-administrator (chief of gastroenterology) at the same hospital. The article describes eight distinctive aspects of administrator-physicians as patients, including special patient treatment; exalted patient expectations by hospital personnel; patient suppression of emotions; patient denial; self-doctoring; job stress contributing to disease; self-sacrifice to achieve better health; and rational medical decisions when not under stress. Health-care workers should recognize how these distinctive aspects of medical care and behavior affect administrator-physicians as patients, in order to mitigate their negative effects, potentiate their positive effects, and optimize the care of these patients.

Social Capital and Walkability as Social Aspects of Sustainability

Directory of Open Access Journals (Sweden)

Shannon H. Rogers

2013-08-01

Full Text Available The concepts of sustainability and sustainable development are frequently described as having three main components, sometimes referred to as the three pillars or the triple bottom line: environmental, economic, and social. Because of an historical focus in the sustainability field on correcting environmental problems, much consideration has been given to environmental issues, especially how they interface with economic ones. Frequently mentioned but rarely examined, the social aspects of sustainability have been considered the weakest and least described pillar. After a brief review of existing concepts and theories, this paper uses a case study approach to examine the third pillar more comprehensively and offers social capital as one measure of social sustainability. Specifically, social capital was used to measure the social-environmental interface of communities. The positive correlation between aspects of the built environment, specifically walkability, and social capital suggests that measuring a social aspect of sustainability may be feasible, especially in the context of community development.

Influence of obstacle aspect ratio on tripped cylinder wakes

Highlights: ► Influence of a tripwire on wake properties of a surface-mounted circular cylinder. ► Height-to-diameter aspect ratios of 3 and 6 are considered. ► Critical positions for the tripwire lead to an abrupt change in the wake structure. ► Results further suggest that the tripwire can strengthen 2D wake properties. - Abstract: The influence of an asymmetrically mounted, single tripwire on the shedding and wake characteristics of a vertical, surface-mounted finite circular cylinder is investigated experimentally. Height-to-diameter aspect ratios of 3 and 6 are considered. It is shown that a critical position for the tripwire exists, which is characterised in an abrupt change in the shedding frequency and wake structure. Results further suggest that the tripwire can strengthen 2D wake properties. The influence of the aspect ratio is due to tip-wake flow interactions and thus differs fundamentally from two-dimensional geometries.

A REVIEW: A MODEL of CULTURAL ASPECTS for SUSTAINABLE PRODUCT DESIGN

Directory of Open Access Journals (Sweden)

Ihwan Ghazali,

2012-04-01

Full Text Available Product design stages are important to consider critically in production. Generally, product design that shall be created by designer, should consider what the customer wants and needs. Nowadays issues, product design does not only consider the “wants and needs” of user, but also how the design can be created by embedding sustainability aspects in the product. Culture is also one of the important aspects which need to be considered in product design as culture affects the way users respond to the product. This paper aims to develop a new model for design development, in which the aspects of culture are incorporated into sustainable product design. By reviewing the existing literature, the authors attempt to identify the gaps of the existing papers, which illustrate how culture affects sustainable product design. Recent papers have only shown that culture influences product design, but they do not explore sustainability and the culture aspects in product design. Due to these gaps, it is therefore important to create a model which will assist designers to elicit sustainable product design based on cultural aspects. In summary, designers need to reflect on the “wants and needs” of users. The framework presented in this paper can be integrated into designers’ and companies’ decision-making during product design development.

To correlate quality of life of children in terms of sleep, with their oral language skills, auditory processing and orofacial myofunctional aspects. Nineteen children (12 males and seven females, in the mean age 9.26) undergoing otorhinolaryngological and speech evaluations participated in this study. The OSA-18 questionnaire was applied, followed by verbal and nonverbal sequential memory tests, dichotic digit test, nonverbal dichotic test and Sustained Auditory Attention Ability Test, related to auditory processing. The Phonological Awareness Profile test, Rapid Automatized Naming and Phonological Working Memory were used for assessment of the phonological processing. Language was assessed by the ABFW Child Language Test, analyzing the phonological and lexical levels. Orofacial myofunctional aspects were evaluated through the MBGR Protocol. Statistical tests used: the Mann-Whitney Test, Fisher's exact test and Spearman Correlation. Relating the performance of children in all evaluations to the results obtained in the OSA-18, there was a statistically significant correlation in the phonological working memory for backward digits (p = 0.04); as well as in the breathing item (p = 0.03), posture of the mandible (p = 0.03) and mobility of lips (p = 0.04). A correlation was seen between the sleep quality of life and the skills related to the phonological processing, specifically in the phonological working memory in backward digits, and related to orofacial myofunctional aspects.

Aspect-Oriented Business Process Modeling with AO4BPMN

Science.gov (United States)

Charfi, Anis; Müller, Heiko; Mezini, Mira

Many crosscutting concerns in business processes need to be addressed already at the business process modeling level such as compliance, auditing, billing, and separation of duties. However, existing business process modeling languages including OMG's Business Process Modeling Notation (BPMN) lack appropriate means for expressing such concerns in a modular way. In this paper, we motivate the need for aspect-oriented concepts in business process modeling languages and propose an aspect-oriented extension to BPMN called AO4BPMN. We also present a graphical editor supporting that extension.

Transient Aspects of Wave Propagation Connected with Spatial Coherence

Directory of Open Access Journals (Sweden)

Ezzat G. Bakhoum

2013-01-01

Full Text Available This study presents transient aspects of light wave propagation connected with spatial coherence. It is shown that reflection and refraction phenomena involve spatial patterns which are created within a certain transient time interval. After this transient time interval, these patterns act like a memory, determining the wave vector for subsequent sets of reflected/refracted waves. The validity of this model is based on intuitive aspects regarding phase conservation of energy for waves reflected/refracted by multiple centers in a certain material medium.

Tamara Hubanova

2017-12-01

Full Text Available The increased danger of environmental crime is primarily determined by an increase in anthropogenic pressure on the natural environment, which, in the conditions of the global environmental crisis, threatens to cause significant, often non-renewable, damage to the vital interests of man, society, and the state. Ukraine belongs to the countries with the worst ecological situation. Pollution of the environment reached unprecedented levels in recent years. The purpose of the study is to reveal the essence and causes of environmental crime in Ukraine, socioeconomic aspects of the identified phenomenon, analyse the impact of negative consequences of environmental crime on the Ukrainian economy, as well as study legal aspects of criminal liability for environmental crimes and international legal standards on the raised issues. The subject of the study is the socio-economic and legal aspects of environmental crime in Ukraine. Methodology. In order to achieve the goal, the authors of the study carried out an analysis of the definition of the system of environmental crimes in the scientific literature, various statistical data on the state of the ecological situation and crime in Ukraine, as well as laws and regulations defining the national environmental policy of Ukraine.

COMPARATIVE ANALYSIS OF INNOVATION ASPECT EVIDENCE IN CONSTRUCTION AND MULTI-SECTOR COMPANIES

Directory of Open Access Journals (Sweden)

Ricardo Floriani

2010-12-01

Full Text Available The goal of this study is to make a comparative analysis of innovation aspect evidence among construction and multi-sector companies. Descriptive research was done through a content analysis of administration reports from 2005 to 2007. From the researched material, 14 aspects of innovations were extracted, which offer the basis to the content analysis. Two non-probability samples were developed, the first consisting of 22 multi-sector businesses, within 18 economic sectors, which comprises the companies in the comparison. Aspects of innovation found in this group of companies were compared to those stated in the reports of the administration of the 34 construction companies with open capital, which comprise the second sample. The survey results show that the evidence of innovation aspects are different in construction companies when compared to the administration reports of multi-sector business of 2005, 2006 and 2007. The construction companies state fewer innovation aspects in the administration reports than multisector companies in the analyzed period. The conclusion is that while construction companies can be considered fairly innovative, multi-sectorial companies present more innovations on average.

Two aspects of the quantum chromodynamics' transition at finite temperature

International Nuclear Information System (INIS)

Zhang, Bo

2011-01-01

This thesis concerns two aspects of the relation between chiral symmetry breaking and confinement. The first aspect is the relations between different topological objects. The relation between monopoles and center vortices and the relation between instantons and monopoles are well established, in this thesis, we explore the relation between instantons (of finite temperature, called calorons) and center vortices in SU(2) and SU(3) gauge theory in Chapter 3 and Chapter 4, respectively. The second aspect is about the order parameters. The dual condensate introduced by E. Bilgici et al. is a novel observable that relates the order parameter of chiral symmetry breaking (chiral condensate) and confinement (Polyakov loop). In this thesis, we investigate the dual condensate on dynamical staggered fermions and explore a new dual operator: the dual quark density in Chapter 5.

Shaping the pain: Ancient Greek lament and its therapeutic aspect?

Directory of Open Access Journals (Sweden)

Šijaković Đurđina

2011-01-01

Full Text Available In this paper, which is the first part of a wider research, I focus on different aspects of ancient Greek lament. One of its most important aspects is the therapeutic aspect: by verbalizing, revealing the pain and by sharing it with others, the pain itself is becoming more bearable both for the woman that laments and for the bereaved family. Related to this therapeutic is the creative aspect of lament: the woman that mourns has to lament in order to make it easier for herself and others; but while lamenting, she is creating something. In spite of this constructive, let us call it creative-therapeutic potential, the lament carries in itself a different, rather dark and gloomy potential, if it calls for vengeance, not reconciling with the fact of someone dear’s death. Deeply rooted in funeral ritual, a lament respects certain ritual rules, and yet it is a spontaneous expression of pain. Examining these mutually dependent aspects of lament, I will turn attention to the position of lament in Greek rites and tragedy, that summit Greek art and literature. Ritual lament within ancient tragedy is, as always when it comes to Greek culture, an inexhaustible topic. Although tragedy belongs to literary tradition, it is a trustworthy source for ancient Greek ritual practice; lament within tragedy is thus a ritual lament, and not only a literary one. Characters of many tragedies will mention the therapeutic aspect of lament, examined in this paper: they consider tears, wails and words directed to the deceased as joyful service, enjoyment, music, song precious and indispensable. This paper has its supplement, shaping the pain in few case studies. Inspired by laments of Montenegrin women, those that I have heard or read, I am re-reading Euripides’ Electra and Electra by Danilo Kiš (in which both Euripides’ drama and Montenegrin folklore is reflected, I am watching the Michalis Kakojannis’ movie Electra. Electra’s pain for loss, the one that through

1975-01-01

Indexed and abstracted references to the environmental aspects of the transuranium elements are entered into and are retrievable from a dynamic, computerized information file (or data base) that is easily modified to reflect changing research needs. The information is distilled from the documents with the specific needs of the researcher in mind, such as numeric results, new methods, or instrumentation. The major areas of evaluation are: biological and medical studies on the effects of the transuranics, particularly as these elements relate to health considerations in man; biological and ecological availability, turnover, and food chain dynamics; analysis of environmental materials; environmental transport mechanisms, including resuspension; waste disposal as related to environmental concerns; monitoring; and regulations and standards for environmental levels. Annotated references are indexed to allow easy access for retrieving references to documents of interest to the user. The goal is to furnish the users all the references related to their specific query and few that are unrelated. This is done by liberal use of subject categories and keyterms. The studies on man and animals are divided into the subject categories of medical and biological aspects. Those aspects that are considered important when the document is analyzed are tabulated. These data are sought for in the article, included in the abstracts, and indexed with keyterms. This checklist is one of the ways the Data Base on the Environmental Aspects of the Transuranics strives to give users a reference to every paper in their subject area

Black liquor gasification (BLG) is one of the high-prioritized RandD areas in Sweden. Research work is going on in the national program BLG-Programme. The main aims with the present study are to: - Identify larger projects dealing with energy oriented system aspects of BLG - Make a synthesis on system aspects results in these projects - Identify need for further work, e.g. as a part of a second period of the BLG Programme. No new work or calculations have been performed, the aim has been only to compile and draw conclusions from existing information. The focus has been on system studies. Most of the research on BLG has been technically, chemically and component oriented. These areas are not included in this report. In Chapter 2 basics for BLG are presented and in Chapter 3 important system aspects of this technology are discussed. Future opportunities for energy savings in mills are crucial for a BLG system, both technically and economically. Therefore present knowledge for such opportunities is presented in Chapter 4. In section 1.4 the report/projects included in this report are introduced and in Chapter 5-13 Summaries, especially on system aspects, of these reports are given. In order to keep the report at a reasonable size only major projects dealing with system aspects during the last 10 year period have been included. In Chapter 14 a synthesis of system aspects dealt with in the different reports is presented and in Chapter 15 suggestions for further work are given. In Chapter 16 references are given and finally in the Attachment a brief overview of different BLG technologies is presented

Combining Static Analysis and Runtime Checking in Security Aspects for Distributed Tuple Spaces

DEFF Research Database (Denmark)

Yang, Fan; Aotani, Tomoyuki; Masuhara, Hidehiko

2011-01-01

Enforcing security policies to distributed systems is difficult, in particular, to a system containing untrusted components. We designed AspectKE*, an aspect-oriented programming language based on distributed tuple spaces to tackle this issue. One of the key features in AspectKE* is the program...... analysis predicates and functions that provide information on future behavior of a program. With a dual value evaluation mechanism that handles results of static analysis and runtime values at the same time, those functions and predicates enable the users to specify security policies in a uniform manner....... Our two-staged implementation strategy gathers fundamental static analysis information at load-time, so as to avoid performing all analysis at runtime. We built a compiler for AspectKE*, and successfully implemented security aspects for a distributed chat system and an electronic healthcare record...

Neurological aspects of lead intoxication

Energy Technology Data Exchange (ETDEWEB)

Lehner, H

1980-05-08

This study gives a survey over the medical and scientific literature on lead intoxications, which were published until 1979. Neurologic aspects are of particular interest. At present dramatic cases of lead intoxications occur only rarely. However, there are numerous studies about cases of chronical, partly subclinical intoxications. This chronical type of lead intoxication can become manifest clinically as relatively vague symptoms, for example vertigos, insomnia, headaches and weakness. Contrary to this, serious encephalopathies, even with fatal outcome, and polyneuropathies with typical paresis of the radial nerve are preferably observed in acute lead intoxications. Besides the numerous sources of intoxication, also the different opinions found in literature are discussed, concerning the effects of lead on the human body. The fact that there are differing opinions about the limiting value of the blood-lead level at which intoxication symptoms have to be expected, becomes apparent when the determined blood-lead level values are compared and evaluated. Besides the description of general intoxication effects, the discussion of the neurologic aspects found in literature - not only those concerning the central, but also the peripheral system - are preferably concerned. Reports about neuropsychical alterations due to lead exposure, which are mainly found in children, supplement the numerous descriptions of the macroscopic and microscopic alterations of the nervous system provoked by lead. Finally the therapeutic and prophylactic measures given in the literature are discussed.

Holistic aspects of children's ways of understanding in making sense of genetics

Science.gov (United States)

Huang, Hui-Ju

The study examined the nature of how children make sense of phenomena in the area of genetics and inheritance. I proposed the phrase, way of understanding to capture a unified entity which children use to make sense of phenomena. The methodology was semi-structured probing interviews with six sixth grade students. Seven specific ways of understanding were discussed in the results section. Overall, the study described and discovered children's ways of understanding in terms of five aspects: cognitive aspects, affective aspects, social aspects, playfulness, and mode of awareness. Students' propositional knowledge, a holistic view of looking at how people resemble each other, syntactic knowledge, and an extension of rational explanations belonged to the cognitive aspects. Four categories of affective expressions were: an enjoyment of thinking and learning, a special feeling about the instructional activity, a deep personal involvement, and an anxiety in finding correct answers. Two types of social context were identified, one had somewhat of a connection to the science world, and the other did not have much of an scientific tie. The playfulness and the mode of awareness were two emerging aspects through the study. The playfulness represented the spontaneity, freedom, and sense of fun associated with the social interaction activity, such as the playfulness in expressing ideas to others. The modes of awareness included two types of metacognition, one was a conscious reflection on one's cognitive abilities, and the other was a continuous process of monitoring knowledge. In addition, the importance of considering language aspect in science learning was an emerging issue. Students' talking about genetics was embedded in the larger framework of social relationships and social institutions. Their social identify might influence the development of concepts, ways of talking and science learning. The study reflects the richness of children's sense-making processes

OCLATOR (One Coil Low Aspect Toroidal Reactor)

Energy Technology Data Exchange (ETDEWEB)

Yoshikawa, S.

1980-02-01

A new approach to construct a tokamak-type reactor(s) is presented. Basically the return conductors of toroidal field coils are eliminated and the toroidal field coil is replaced by one single large coil, around which there will be placed several tokamaks or other toroidal devices. The elimination of return conductors should, in addition to other advantages, improve the accessibility and maintainability of the tokamaks and offer a possible alternative to the search for special materials to withstand large neutron wall loading, as the frequency of changeover would be increased due to minimum downtime. It also makes it possible to have a low aspect ratio tokamak which should improve the ..beta.. limit, so that a low toroidal magnetic field strength might be acceptable, meaning that the NbTi superconducting wire could be used. This system is named OCLATOR (One Coil Low Aspect Toroidal Reactor).

A Model for Assessing the Gender Aspect in Economic Policy

Directory of Open Access Journals (Sweden)

Ona Rakauskienė

2015-06-01

Full Text Available The purpose of research is to develop a conceptual model for assessing the impact of the gender aspect on economic policy at macro– and microeconomic levels. The research methodology is based on analysing scientific approaches to the gender aspect in economics and gender–responsive budgeting as well as determining the impact of the gender aspect on GDP, foreign trade, the state budget and the labour market. First, the major findings encompass the main idea of a conceptual model proposing that a socio–economic picture of society can be accepted as completed only when, alongside public and private sectors, includes the care/reproductive sector that is dominated by women and creating added value in the form of educated human resources; second, macroeconomics is not neutral in terms of gender equality. Gender asymmetry is manifested not only at the level of microeconomics (labour market and business but also at the level of macroeconomics (GDP, the state budget and foreign trade, which has a negative impact on economic growth and state budget revenues. In this regard, economic decisions, according to the principles of gender equality and in order to achieve gender equality in economics, must be made, as the gender aspect has to be also implemented at the macroeconomic level.

Kuwaiti oil wells blowout - aspects and effects

International Nuclear Information System (INIS)

Al-Jassim, F.

1992-01-01

When the Iraqi troops were forced to leave Kuwait, they left behind them the greatest oil catastrophe human beings have ever experienced. Fire plumes of tons of gases of principal pollutants, hydrocarbons, soot and associated metals were ejected up to a height of about 5 km. The retreating forces blew off about 1200 wells all over Kuwait fields. Of these 1200 wells, 614 are on fire. Four firefighting companies were hired to start work immediately after the liberation of Kuwaiti to control these wells. Three of these companies were from the U.S.A. and one from Canada. The number of these companies steadily increased along with logistical support. There are now 28 teams made up of private and multinational companies. This paper will concentrate on two main aspects. The first part will focus on the up-to-date engineering aspects of bringing the blown-out wells under control, focusing on oil well fires and the difficulties encountered, such as equipment availability, ordnance clearance and logistical support. The paper then describes the procedures used to control the wells, and the steps taken to reach this aim are presented. Finally the number of wells controlled, area-wise in different fields, with their original status, is also introduced. The second part will concentrate on the environmental aspects, covering the impact of the plumes on air quality, air pollution and health. The paper then discusses the effect on marine environment, vegetation and the soil. Finally, a forecast, conclusions and recommendations are presented. (author)

, comprehensibility and evolvability. As (aspect) languages are being pushed to meet their boundaries and limitations, the trade-offs in language design become increasingly difficult to make. In particular, a trade-off may be perfectly sensible in one application context, but much less so in another. In this special...... issue you will find three full papers, originating from the SPLAT workshop series, that address this last issue. Each of these papers resolves a fundamental language design trade-off by offering a language mechanism that lifts the design decisions to the application programmers: The first paper, "User......-Defined Join Point Selectors-An Extension Mechanism for Pointcut Languages" by Breuel and Reverbel, addresses the fact that aspect programmers are pushing the boundaries of pointcut languages. As a result, aspect language designers have to make a trade-off between limited expressiveness of traditional types...

The use of modulated toroidal coils offers a new path to the tokamak-stellarator hybrids. Low-aspect-ratio configurations can be found with robust vacuum flux surfaces and rotational transform close to the transform of a reverse-shear tokamak. These configurations have clear advantages in minimizing disruptions and their effect and in reducing tokamak current drive needs. They also allow the study of low-aspect-ratio effects on stellarator confinement in small devices

Effect of channel aspect ratio on chemical recuperation process in advanced aeroengines

International Nuclear Information System (INIS)

Zhang, Silong; Cui, Naigang; Xiong, Yuefei; Feng, Yu; Qin, Jiang; Bao, Wen

2017-01-01

The working process of an advanced aeroengine such as scramjet with endothermic hydrocarbon fuel cooling is a chemical recuperative cycle. The design of cooling channel in terms of engine real working conditions is very important for the chemical recuperation process. To study the effects of channel aspect ratio (AR) on chemical recuperation process of advanced aeroengines, three dimensional model of pyrolysis coolant flow inside asymmetrical rectangular cooling channels with fins is introduced and validated through experiments. Cases when AR varies from 1 to 8 are carried out. In the pyrolysis zone of the cooling channel, decreasing the channel aspect ratio can reduce the temperature difference and non-uniformity of fuel conversion in the channel cross section, and it can also increase the final conversion and corresponding chemical heat absorption. A small channel aspect ratio is beneficial for the chemical recuperation process and can guarantee the engine cooling performance in the pyrolysis zone of the cooling channel. - Highlights: • Large non-uniformity of conversion is bad for the chemical recuperation. • Small channel aspect ratio is beneficial for improving the chemical recuperation effectiveness. • Small channel aspect ratio is also beneficial for reducing the engine wall temperature.

The present study deals with the control of a Mach 2 elliptic jet from a convergent–divergent elliptic nozzle of aspect ratio 4 using tabs at the nozzle exit. The experiments were carried out for rectangular and triangular tabs of the same blockage, placed along the major and minor axes of the nozzle exit, at different levels of nozzle expansion. The triangular tabs along the minor axis promoted superior mixing compared to the other controlled jets and caused substantial core length reduction at all the nozzle pressure ratios studied. The rectangular tabs along the minor axis caused core length reduction at all pressure ratios, but the values were minimal compared to that of triangular tabs along the minor axis. For all the test conditions, the mixing promotion caused by tabs along the major axis was inferior to that of tabs along the minor axis. The waves present in the core of controlled jets were visualized using a shadowgraph. Comparison of the present results with the results of a controlled Mach 2 elliptic jet of aspect ratio 2 (Aravindh Kumar and Sathakrishnan 2016 J. Propulsion Power 32 121–33, Aravindh Kumar and Rathakrishnan 2016 J. Aerospace Eng. at press (doi:10.1177/0954410016652921)) show that for all levels of expansion, the mixing effectiveness of triangular tabs along the minor axis of an aspect ratio 4 nozzle is better than rectangular or triangular tabs along the minor axis of an aspect ratio 2 nozzle.

Chemical aspects of nuclear waste treatment

International Nuclear Information System (INIS)

Bond, W.D.

1980-01-01

The chemical aspects of the treatment of gaseous, liquid, and solid wastes are discussed in overview. The role of chemistry and the chemical reactions in waste treatment are emphasized. Waste treatment methods encompass the chemistry of radioactive elements from every group of the periodic table. In most streams, the radioactive elements are present in relatively low concentrations and are often associated with moderately large amounts of process reagents, or materials. In general, it is desirable that waste treatment methods are based on chemistry that is selective for the concentration of radionuclides and does not require the addition of reagents that contribute significantly to the volume of the treated waste. Solvent extraction, ion exchange, and sorbent chemistry play a major role in waste treatment because of the high selectivity provided for many radionuclides. This paper deals with the chemistry of the onsite treatment methods that is typically used at nuclear installations and is not concerned with the chemistry of the various alternative materials proposed for long-term storage of nuclear wastes. The chemical aspects are discussed from a generic point of view in which the chemistry of important radionuclides is emphasized

The water pool in the wet scrubber system has advantage to cope with decay heat based on the thermal hydraulic balance such as condensation and evaporation inside it. This study focuses on the design aspects of the wet scrubber system to estimate the required water pool mass during the mission time and size of the scrubbing tank including inner structures. The design of the wet scrubber system include the estimation of the required water mass during the mission time and sizing of the scrubber vessel to contain the water pool. The condensation due to the inlet steam and evaporation due to the steam and non-condensable gas superheat and decay heat from filtered fission products should be considered to estimate the water mass required to maintain its function during the mission time. On the other hand, the level swelling due to the noncondensable gas is another important design aspect on the sizing of the scrubber vessel and determination of the entry elevation of the filtration components such as the droplet separator or filter. The minimum water level based on the minimum collapsed water level should be higher than the exit of scrubber nozzle

Aspect-Driven Changes in Slope Stability Due to Ecohydrologic Feedbacks

Seasonally integrated variation in insolation drives feedbacks among evapotranspiration, soil moisture, weathering, and erosion that lead to pronounced contrasts in slope angles and vegetation on north and south-facing hillslopes. Spatial variations in insolation associated with north-south contrasts in topographic aspect leads to corresponding variation in local microclimates and ecohydrologic regimes that, in turn, impact spatial patterns of weathering and erosion, ultimately impacting slope angles on north and south-facing slopes. Aspect-sensitive environments appear to be poised on a balance point between ecohydrologic systems, and may be especially susceptible to climate change. In the semi-arid Colorado Plateau of northeastern Arizona, cliffs often form on south-facing slopes where soil moisture is insufficient for weathering of clay-cemented sandstone that is susceptible to hydration. In contrast, cliffs are rare on northerly slopes, which are dominated by mantles of weathered sandstone and colluvium (Burnett et al., 2008, doi:10.1029/2007JF000789). However, in semi-arid regions of the Idaho Batholith, preliminary results indicate some north-facing slopes are significantly steeper than south-facing slopes. We hypothesize that in semi-arid areas with observable increases in vegetation on north vs. south-facing slopes, north-facing slopes will be steeper due to increased soil cohesion, increased capture of wind-borne loess due to vegetative wind-baffling, and differences in the type and magnitude of erosive processes. In moister areas where aspect does not visibly control vegetation type and density, differences in slope angles with aspect should not be observed. We investigate tectonically quiescent regions of the mostly-homogenous granodioritic Idaho Batholith to locate areas sensitive to aspect-induced variations in insolation and compare slope characteristics on north and south-facing slopes.
