Full Text Available Background: The rapid expansion of trials in emerging regions has raised valid concerns about research subject protection, particularly related to informed consent. The purpose of this study is to assess informed consent form (ICF compliance with Good Clinical Practice (GCP guidelines and the readability easeof the ICFs in Abu Dhabi, a potential destination for clinical trials in the UAE. Materials and Methods: A multicenter retrospective cross-sectional analysis of 140 ICFs from industry sponsored and non-sponsored studies was conducted by comparing against a local standard ICF. Flesch-Kincaid Reading Scale was used to assess the readability ease of the forms. Results: Non-sponsored studies had signifi cantly lower overall GCP compliance of 55.8% when compared to 79.5% for industry sponsored studies. Only 33% of sponsored and 16% of non-sponsored studies included basic information on the participants′ rights and responsibilities. Flesch-Kincaid Reading ease score for the informed consent forms from industry sponsored studies was signifi cantly higher 48.9 ± 4.8 as compared to 38.5 ± 8.0 for non-sponsored studies, though both were more complex than recommended. Reading Grade Level score was also higher than expected, but scores for the ICFs from the industry sponsored studies were 9.7 ± 0.7, signifi cantly lower as compared to 12.2 ± 1.3 for non-sponsored studies. Conclusion: In spite of the undisputed benefits of conducting research in emerging markets readability, comprehension issues and the lack of basic essential information call for improvements in the ICFs to protect the rights of future research subjects enrolled in clinical trials in the UAE.

Full Text Available Aim. To study the effect of hemofi ltration and coupled plasma fi ltration adsorption on tacrolimus blood concentration in renal transplant recipients.Methods and results. The study included 8 renal transplant recipients. In these patients immediately after the operation was performed the coupled plasma fi ltration adsorption with hemofiltration using a cartridge Mediasorb to reduce the severity of reperfusion injury. We have found that during this extracorporeal blood correction procedure there was statistically not signifi cant decrease of tacrolimus blood concentration. However, concentration of tacrolimus remained in the therapeutic range even after the procedure and it was not signifi cantly different from the control point С0.Conclusion. Coupled plasma fi ltration adsorption is safe in renal transplant recipients and has no signifi cant impact on tacrolimus blood concentration. However, the downward trend in the concentration of tacrolimus in the course of these procedures, especially in continuous or semicontinuous mode, as well as in patients with low hematocrit and hypoalbuminemia, requires individual monitoring.

Full Text Available Existi ng literature has not yet defi ned a clear-cut relati onship between ownership structure and capital structure. This study aims to contribute to this controversial argument by examining the impact of internal (managerial ownership and external ownership on fi nancing preferences using the case of non-fi nancial fi rms listed on Karachi stock exchange during the period of 2008-2012. Our results suggest that the external ownership has a signifi cant eff ect on capital structure in accordance with the presence of blockholders. In contrast, the internal ownership has a complicated eff ect; it shows signifi cant positi ve and negati ve relati onship to leverage at lower and certain higher proporti on of managerial shareholding respecti vely. Besides, the combined analyses suggest that the presence of blockholders negates the impact of managerial ownership on capital structure. This implies that the presence of large and dominant shareholders in Pakistani fi rms may have caused a bias for debt fi nancing to protect their voti ng power and returns.

Full Text Available Concentration and recentralization can be described as a European trend in the fi eld of local governance, especially in the fi eld of the administration of rural areas. An important tool of the concentration of the local administration is the intercommunal cooperation. The Hungarian rural areas have fragmented spatial structures. Because of the fragmentation and the small number of the voluntary associations these types of local cooperation were signifi cantly supported by the central budget in the 1990s and 2000s. The economic crisis resulted in a strong concentration trend in Hungary, as well. The new Hungarian Municipal Code introduced a Janus-faced model. The administration of the rural areas was strongly concentrated by the establishment of the mandatory common municipal offi ces of the small villages (under 2000 inhabitants while the forms of the intercommunal associations were simplifi ed.

Full Text Available Introduction: Dental caries is one of the most common conditions affecting the general health of children. The present study was carried out among school children of Kathmandu valley to determine the prevalence of dental caries in two age groups. Methods: The study was conducted from December 2007 to May 2008. The age of the school children of the study was divided into two group: 5 - 6 years and 12 - 13 years. A stratifi ed cluster sampling with proportional allocation was used while grouping the subjects. The dental status examination was done with the help of trained dentists. Decayed, missed and fi lled teeth index and decayed, missed and fi lled surfaces index (dmft for primary dentition and DMFT for permanent dentition were used as the standard tools for the determination of prevalence. Results: A total of 638 students (325 of age group 12 - 13 years and 313 of age group 5 - 6 years from 30 different schools of the Kathmandu valley were included in the study. The caries status was found higher in the age group of 5 - 6 years than in the 12 - 13 years and it was found to be statistically signifi cant (p < 0.001. The dmfs and caries percentage of the age group 5 - 6 years and the DMFS and caries percent of the 12 - 13 years was found to be 3.79, 69 % and 1.6, 53.23 % respectively. The dmft/dmfs value was found to be signifi cant according to the districts in the 5 - 6 years age group whereas the DMFS was found statistically signifi cant among the sexes of the 12 - 13 years age group. Conclusions: The caries percentage was found to be above the recommended level of the World Health Organization. However, the DMFS and DMFT values were within the WHO level.

A number of canted undulators will be installed at the ESRF. Permanent Magnet Steerers will be used for providing canting angles up to 5.4 mrad. These steerers have been optimized in view of the limited space available and the required field quality. The magnetic interaction between the steerers and the undulators may lead to additional optical phase errors: auxiliary poles have been added to obtain a fast decrease of the fringe field. The transverse homogeneity of the magnetic field integral is another strong design constraint. Good homogeneity was reached by optimizing the profiles of the iron poles. Eight steerers have been constructed and magnetic measurements have been performed.

Urban informality as a signifier: Performing urban reordering in suburban Rio de Janeiro.

Müller, Frank I

2017-07-01

Urban informality is typically ascribed to the urban poor in cities of the Global South. Drawing on Judith Butler's concept of performativity and taking the case of Rio de Janeiro in the context of the 2016 Olympic Games, this article conceptualizes informality as a signifier and a procedural, relational category. Specifically, it shows how different class actors have employed the signifier informality (1) to legitimize the confinement of marginalized populations; (2) to justify the organized efforts of the upper middle class to protect their 'self-enclosed' gated communities; and (3) to warrant the formation of opposition and alliances between inhabitants, activists, and researchers on the edges of the urban order. This article offers new perspectives to better understand the relationship between informality and confinement by examining the active role that inhabitants of marginalized settlements assume in the Olympic City.

Full Text Available Normal 0 false false false IN X-NONE AR-SA MicrosoftInternetExplorer4 This research aims to study the intentions of students in entrepreneurship by using the theory of planned behavior of Fishbein and Ajzein. This study was conducted in six state universities in In- donesia, namely University A in Northern Sumatra, University B in Western Sumatra, University C in Jakarta, University D in Yogyakarta, University E in Eastern Java and University F in Southern Sulawesi with total sample of 600 fi nal year students. Data were analyzed using descriptive and in- ferential statistics using SPSS 11.5 and structural equation models using LISREL software to test the models. The result shows that the theory of planned behavior is proven signifi cant to predict students’ entrepreneurial intention simultaneously in those six universities, whereas subjective norm was the strongest variable in the modeling. However, signifi cant differences were found between results from each university, when analyzed separately. The model has different partial impact in each university, whereas the model only worked signifi cantly in University D and F. Meanwhile, in University A, B and E some variables do not signifi cantly infl uenced entrepreneurial intention and for University C, we believe that there are other variables that may explain the students’ entrepreneurial intention in University C since the model proved insignifi cantly to predict their entrepreneurial intention. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin-top:0cm; mso-para-margin-right:0cm; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0cm; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso

Previously, we identified the calcium-activated nucleotidase 1 (CANT1) transcript as up-regulated in prostate cancer. Now, we studied CANT1 protein expression in a large cohort of nearly 1000 prostatic tissue samples including normal tissue, prostatic intraepithelial neoplasia (PIN), primary carcinomas, metastases, and castrate-resistant carcinomas, and further investigated its functional relevance. CANT1 displayed predominantly a Golgi-type immunoreactivity with additional and variable cytoplasmic staining. In comparison to normal tissues, the staining intensity was significantly increased in PIN lesions and cancer. In cancer, high CANT1 levels were associated with a better prognosis, and castrate-resistant carcinomas commonly showed lower CANT1 levels than primary carcinomas. The functional role of CANT1 was investigated using RNA interference in two prostate cancer cell lines with abundant endogenous CANT1 protein. On CANT1 knockdown, a significantly diminished cell number and DNA synthesis rate, a cell cycle arrest in G1 phase, and a strong decrease of cell transmigration rate and wound healing capacity of CANT1 knockdown cells was found. However, on forced CANT1 overexpression, cell proliferation and migration remained unchanged. In summary, CANT1 is commonly overexpressed in the vast majority of primary prostate carcinomas and in the precursor lesion PIN and may represent a novel prognostic biomarker. Moreover, this is the first study to demonstrate a functional involvement of CANT1 in tumor biology. PMID:21435463

Full Text Available The aim of this research is to determine whether there is any statistically signifi cant diff erence in motor abilities of boys and girls of younger school age. The sample includes 76 examinees with 37 males and 39 females. All are 5th and 6 th graders of primary school. The evaluation of motor abilitied is based on 5 tests. Multivariant analysis of variance is applied for determination of diff erences within the whole system of motor tests, whereas univariant analysis of variance is used for determining diff erences in each motor test. According to the fi ndings, statistically signifi cant diff erences in motor abilities between boys and girls at the studied age can be noticed in the test 20 m running from fl ying start, which is in favour of boys and in the test sit and reach, in favour of girls, while the diff erences in other tests are not statistically signifi cant. Considering the evaluation of motor abilities, boys have statistically much better results in the speed of alternative movements and explosive strenth, whereas girls have achieved much better results in the test for fl exibility. It has also been concluded that 5th and 6th graders have statistically better results in the space of coordination and explosive strenght, whereas girls are much better in the fi eld of fl exibility and suppleness.

Full Text Available El fandango en Málaga se manifiesta de muy diversas formas: como verdiales, interpretados por agrupaciones llamadas pandas, que incluyen cante y baile y están acompañadas de guitarras, panderos y platillos; como fandangos abandolaos, que se cantan solo con guitarra y ritmo ternario y desvinculados del baile; como malagueñas, derivadas de los anteriores pero sin ritmo; y como fandangos personales, estilos surgidos a partir de la década de 1920, en la llamada Ópera flamenca, y que son de gran aceptación por el gran público. Desde la figura de Juan Breva (18441918 hasta el actual Álvarez (1947, de quien se ha rodado una película recientemente, el fandango ha sido unos de los estilos folklóricos y flamencos más cultivados en Málaga.

Thermophysiological Properties of Dry and Wet Functional Sportswear Made of Synthetic Fibres

Directory of Open Access Journals (Sweden)

Monika Bogusławska – Bączek

2017-12-01

Full Text Available In recent times, knitted fabrics made from synthetic fibres are being used increasingly for sportswear. This type of clothing should ensure thermal comfort in all weather conditions, regardless of the activity of the wearer. The most important thermal properties include thermal conductivity and resistance, as well as water vapour permeability. Sportswear often becomes wet (from sweat or due to a humid environment, which can have a signifi cant effect on thermal properties, while most testing methods only perform measurements in a dry state. This paper therefore presents our study of the thermal properties of different types of knitted fabrics in both dry and wet states. The presented research proved that wet knitwear results in a signifi cant loss of thermal comfort. This phenomenon is exacerbated when the moisture content of a material increases, and depends on the structure and filling of tested materials.

The degree of alignment of the magnetic moments of Fe3+ ions in ultrafine maghemite particles has been studied in samples with induced magnetic texture. The textured samples were prepared by freezing ferrofluids, containing 7.5 nm maghemite particles, in a magnetic field. Mössbauer spectroscopy...... studies of the textured samples in large magnetic fields demonstrate that the lack of full alignment is not an effect of large magnetic anisotropy, as suggested recently, but that the effect is rather due to canting of individual spins.

2011-09-01

Full Text Available Introduction: High low-density lipoproteins (LDL cholesterol is one of the major risk factors for cardiovascular disease. In recent years, some evidence has been presented that periodontitis,an infectious inflammatory condition of the periodontium, is associated with an increased risk of cardiovascular disease. To further elucidate this association, we have studied the levels of LDL cholesterol, a known risk marker for cardiovascular disease, in a periodontally-diseased group. Methods: The levels of serum LDL cholesterol in 47 subjects with mild to severe (clinical attachment loss equal to or greater than 1 mm chronic generalized (at least 30% of teeth affected periodontitis with the mean age of 42.21 ± 1.46 years were measured and compared with those obtained from 42 age (39.83 ± 0.94 and sex matched controls. Both groups were free from systemic illnesses. Results: The mean serum LDL cholesterol in periodontitis patients was found to be signifi cantly higher (P < 0.001 as compared to that of the controls. The mean clinical attachment loss was positively correlated with serum LDL cholesterol (P < 0.01 and gingival index (P<0.05. The frequency of persons with pathologic values of LDL cholesterol was signifi cantly higher in periodontitis patients compared with that of the controls. Conclusions: These results showed that high serum LDL cholesterol may be associated with periodontitis in healthy people. However, it is unclear whether periodontitis causes an increase in the levels of serum LDL or an increased LDL is a risk factor for both periodontitis and cardiovascular disease. Keywords: Cardiovascular disease, LDL cholesterol, periodontitis.

Full Text Available On the sample of 32 fourth grade students of some Belgrade highs schools, who had the physical education classes carried out at the city’s swimming pools, an attempt was made to evaluate the effects of the two different programmes of swimming training in different intensity zones, defi ned relative to the anaerobic threshold. The examinees were divided into two groups out of 15 i.e. 17 participants who were not (according to statistics signifi cantly different in terms of average time and heart frequency during the 400 m swimming test and heart frequency and time measured after 50 m in the moment of reaching the anaerobic threshold. The fi rst training model consisted of swimming at the intensity level within the zone below anaerobic threshold, while the second model involved occasional swimming at a higher intensity sometimes surpassing the anaerobic threshold. The experimentalprogramme with both sub-groups lasted 8 weeks with 3 training sessions per week, 2 ‘of which we’re identical for both experimental groups, with the third one differing regarding the swimming intensity, this in the fi rst group being still in the zone below, and in the second group occasionally in the zone above the anaerobic threshold. The amount of training and the duration were the same in both programmes. The aim of the research , was to evaluate and to compare the effects of the two training models, using as the basic criteria possible changes of average time and heart frequency during the 400 m swimming test and heart frequency and time measured after 50 m in the moment of reaching the anaerobic thereshold. On the basis of the statistical analysis of the obtained data, it is possible to conclude that in both experimental groups there were statistically signifi cant changes of average values concerning all the physiological variables. Although the difference in effi ciency of applied experimental programmes is not defi ned, we can claim that both of experimental

Defects/strain influenced magnetic properties and inverse of surface spin canting effect in single domain CoFe_2O_4 nanoparticles

International Nuclear Information System (INIS)

Singh, Simrjit; Khare, Neeraj

2016-01-01

Graphical abstract: - Highlights: • Synthesized single domain CoFe_2O_4 nanoparticles with different amount of strain. • Demonstrated a correlation between size, strain and magnetic properties of CoFe_2O_4. • Strain induces cationic redistribution at tetrahedral and octahedral sites of CoFe_2O_4. • Inverse of spin canting effect due to the redistribution of Fe"3"+ ions is demonstrated. - Abstract: Single domain CoFe_2O_4 nanoparticles with different amount of defects/strain have been synthesized by varying the growth temperature in the hydrothermal method. Nanoparticles grown at lower temperature are of larger size and exhibit more planar defects and oxygen vacancies as compared to nanoparticles grown at higher temperatures which are of smaller sizes and exhibit less planar defects and oxygen vacancies. The nanoparticles with larger amount of defects also possess a higher value of intrinsic strain as compared to nanoparticles with fewer defects. The presence of intrinsic strain in the nanoparticles is found to shift the cationic distribution at the tetrahedral and octahedral sites. The saturation magnetization (M_s) of the nanoparticles is found to depend upon both the intrinsic strain and size of the nanoparticles. The M_s increases with the decrease in the nanoparticles size from 32 nm to 20 nm, and this is correlated to the inverse of spin canting effect due to decrease in the intrinsic strain which leads to shifting of Co"2"+ ions from tetrahedral to octahedral sites. However, with further decrease in the size of the nanoparticles (16 nm), the size effect dominates over the strain effect leading to decrease in M_s. The coercivity is found to be higher in the nanoparticles with larger amount of defects/strain and has been attributed to strain induced strong spin canting and pinning due to defect sites. The variation of coercivity with particle size (D) exhibits deviation from D"3"/"2 dependence for the nanoparticles with larger amount of strain/defects.

Terahertz-Frequency Spin Hall Auto-oscillator Based on a Canted Antiferromagnet

Sulymenko, O. R.; Prokopenko, O. V.; Tiberkevich, V. S.; Slavin, A. N.; Ivanov, B. A.; Khymyn, R. S.

2017-12-01

We propose a design of a terahertz-frequency signal generator based on a layered structure consisting of a current-driven platinum (Pt) layer and a layer of an antiferromagnet (AFM) with easy-plane anisotropy, where the magnetization vectors of the AFM sublattices are canted inside the easy plane by the Dzyaloshinskii-Moriya interaction (DMI). The dc electric current flowing in the Pt layer creates due to the spin Hall effect, a perpendicular spin current that, being injected in the AFM layer, tilts the DMI-canted AFM sublattices out of the easy plane, thus exposing them to the action of a strong internal exchange magnetic field of the AFM. The sublattice magnetizations, along with the small net magnetization vector mDMI of the canted AFM, start to rotate about the hard anisotropy axis of the AFM with the terahertz frequency proportional to the injected spin current and the AFM exchange field. The rotation of the small net magnetization mDMI results in the terahertz-frequency dipolar radiation that can be directly received by an adjacent (e.g., dielectric) resonator. We demonstrate theoretically that the radiation frequencies in the range f =0.05 - 2 THz are possible at the experimentally reachable magnitudes of the driving current density, and we evaluate the power of the signal radiated into different types of resonators. This power increases with the increase of frequency f , and it can exceed 1 μ W at f ˜0.5 THz for a typical dielectric resonator of the electric permittivity ɛ ˜10 and a quality factor Q ˜750 .

Nazir, Nazia; Sujesh, M; Kumar, Ravi; Sreenivas, P

2012-01-01

The precision of an arbitrary face-bow in accurately transferring the orientation of the maxillary cast to the articulator has been questioned because the maxillary cast is mounted in relation to arbitrary measurements and anatomic landmarks that vary among individuals. This study was intended to evaluate the sagittal inclination of mounted maxillary casts on two semi-adjustable articulator/face-bow systems in comparison to the occlusal cant on lateral cephalograms. Maxillary casts were mounted on the Hanau and Girrbach semi-adjustable articulators following face-bow transfer with their respective face-bows. The sagittal inclination of these casts was measured in relation to the fixed horizontal reference plane using physical measurements. Occlusal cant was measured on lateral cephalograms. SPSS software (version 11.0, Chicago, IL, USA) was used for statistical analysis. Repeated measures analysis of variance and Tukey's tests were used to evaluate the results (P occlusal cant on the articulators and cephalogram revealed statistically significant differences. Occlusal plane was steeper on Girrbach Artex articulator in comparison to the Hanau articulator. Within the limitations of this study, it was found that the sagittal inclination of the mounted maxillary cast achieved with Hanau articulator was closer to the cephalometric occlusal cant as compared to that of the Girrbach articulator. Among the two articulators and face-bow systems, the steepness of sagittal inclination was greater on Girrbach semi-adjustable articulator. Different face-bow/articulator systems could result in different orientation of the maxillary cast, resulting in variation in stability, cuspal inclines and cuspal heights.

Significant benefits have been demonstrated with the use of peri-operative checklists. We assessed whether a read-aloud didactic action card would improve performance of cannula cricothyroidotomy in a simulated 'can't intubate, can't oxygenate' scenario. A 17-step action card was devised by an expert panel. Participants in their first 4 years of anaesthetic training were randomly assigned into 'no-card' or 'card' groups. Scenarios were video-recorded for analysis. Fifty-three participants (27 no-card and 26 card) completed the scenario. The number of steps omitted was mean (SD) 6.7 (2.0) in the no-card group vs. 0.3 (0.5); p < 0.001 in the card group, but the no-card group was faster to oxygenation by mean (95% CI) 35.4 (6.6-64.2) s. The Kappa statistic was 0.84 (0.73-0.95). Our study demonstrated that action cards are beneficial in achieving successful front-of-neck access using a cannula cricothyroidotomy technique. Further investigation is required to determine this tool's effectiveness in other front-of-neck access situations, and its role in teaching or clinical management. © 2016 The Association of Anaesthetists of Great Britain and Ireland.

2012-01-01

Full Text Available Context: The precision of an arbitrary face-bow in accurately transferring the orientation of the maxillary cast to the articulator has been questioned because the maxillary cast is mounted in relation to arbitrary measurements and anatomic landmarks that vary among individuals. Aim: This study was intended to evaluate the sagittal inclination of mounted maxillary casts on two semi-adjustable articulator/face-bow systems in comparison to the occlusal cant on lateral cephalograms. Materials and Methods: Maxillary casts were mounted on the Hanau and Girrbach semi-adjustable articulators following face-bow transfer with their respective face-bows. The sagittal inclination of these casts was measured in relation to the fixed horizontal reference plane using physical measurements. Occlusal cant was measured on lateral cephalograms. SPSS software (version 11.0, Chicago, IL, USA was used for statistical analysis. Repeated measures analysis of variance and Tukey′s tests were used to evaluate the results (P < 0.05. Results: Comparison of the occlusal cant on the articulators and cephalogram revealed statistically significant differences. Occlusal plane was steeper on Girrbach Artex articulator in comparison to the Hanau articulator. Conclusion: Within the limitations of this study, it was found that the sagittal inclination of the mounted maxillary cast achieved with Hanau articulator was closer to the cephalometric occlusal cant as compared to that of the Girrbach articulator. Among the two articulators and face-bow systems, the steepness of sagittal inclination was greater on Girrbach semi-adjustable articulator. Different face-bow/articulator systems could result in different orientation of the maxillary cast, resulting in variation in stability, cuspal inclines and cuspal heights.

Full Text Available The aim of the research was to establish the relationship between the attitude of consumers towards the environment and their behaviours when choosing food products taking into consideration their packaging. This relationship was established according to gender, age and the educational level of the consumers. Questionnaire study was carried out in 2010 within 548 adults from Warsaw. Participants were asked questions on attitudes towards environment and behaviours related to reduction of packaging waste. Frequency, factor and cluster analysis were used. Signifi cantly more women than men agreed that buying pro ducts in larger packages and beverages in glass bottles can reduce the amount of garbage. Over twice more people with positive attitude claimed not buying food in disposable plastic or paper packaging. Negative attitude fostered doing nothing to minimize waste packaging. Attitudes towards the environment have had signifi - cant impact on the choice of food packaging. More positive attitudes favoured the reduction of the amount of packaging waste. Thus, environmental campaigns focused on attitudes and environmentally relevant use of food packing are required.

Factors Governing Intercalation of Fullerenes and Other Small Molecules Between the Side Chains of Semiconducting Polymers Used in Solar Cells

2012-08-22

While recent reports have established signifi cant miscibility in polymer:fullerene blends used in organic solar cells, little is actually known about why polymers and fullerenes mix and how their mixing can be controlled. Here, X-ray diffraction (XRD), differential scanning calorimetry (DSC), and molecular simulations are used to study mixing in a variety of polymer:molecule blends by systematically varying the polymer and smallmolecule properties. It is found that a variety of polymer:fullerene blends mix by forming bimolecular crystals provided there is suffi cient space between the polymer side chains to accommodate a fullerene. Polymer:tetrafl uoro-tetracyanoquinodimethane (F4-TCNQ) bimolecular crystals were also observed, although bimolecular crystals did not form in the other studied polymer:nonfullerene blends, including those with both conjugated and non-conjugated small molecules. DSC and molecular simulations demonstrate that strong polymer-fullerene interactions can exist, and the calculations point to van der Waals interactions as a signifi cant driving force for molecular mixing. © 2012 WILEY-VCH Verlag GmbH & Co.

To compare postoperative maxillary stability following Le Fort I osteotomy for the correction of occlusal cant as compared with conventional Le Fort I osteotomy for maxillary advancement. The subjects were 40 Japanese adults with jaw deformities. Of these, 20 underwent a Le Fort I osteotomy and intraoral vertical ramus osteotomy (IVRO) to correct asymmetric skeletal morphology and inclined occlusal cant. The other 20 patients underwent a Le Fort I osteotomy and sagittal split ramus osteotomy (SSRO) to advance the maxilla. Lateral and posteroanterior cephalograms were taken postoperatively and assessed statistically. Thereafter, the 2 groups were followed for time-course changes. There was no significant difference between the 2 groups with regard to time-course changes during the immediate postoperative period. This suggests that maxillary stability after Le Fort I osteotomy for cant correction does not differ from that after Le Fort I osteotomy for maxillary advancement.

Struvite is a white crystalline that is chemically known as magnesium ammonium phosphorus hexahydrate (MgNH4PO4·6H2O). It can easily dissolve in acidic conditions and slightly soluble in neutral and alkaline conditions. In industry, struvite forms as a scale deposit on a pipe with hot flow fluid. However, struvite can be used as fertilizer because of its phosphate content. A vertical canted reactor is a promising technology for recovering phosphate levels in wastewater through struvite crystallization. The study was carried out with the vertical canted reactor by mixing an equimolar stock solution of MgCl2, NH4OH, and H3PO4 in 1: 1: 1 ratio. The crystallization process worked with the flow rate of three stock solution entering the reactor in the range of 16-38 ml/min, the temperature in the reactor is worked on 20°, 30°, and 40°C, while the incoming air rate is kept constant at 0.25 liters/min. Moreover, pH was maintained at a constant value of 9. The struvite crystallization process run until the steady state was reached. Then, the result of crystal precipitates was filtered and dried at standard temperature room for 48 hours. After that, struvite crystals were stored for the subsequent analysis by Scanning Electron Microscope (SEM) and XRD (X-Ray Diffraction) method. The use of canted reactor provided the high pure struvite with a prismatic crystal morphology.

2015-07-01

Full Text Available BACKGROUND: Bioelectrical impedance (BIA seems an appropriate method for basic diagnostics of body composition in a practical environment. This is a non-time consuming non-invasive method that provides a high degree of response relevance. However, the values identifi ed by the BIA method are susceptible to a number of factors, which need to be taken into account during the investigation stage and interpretation of the results. One of the signifi cant factors infl uencing the outcomes of measurement is the instrument factor.OBJECTIVE: The objective of the present comparative survey was to analyse the proportions of body fat by means of the BIA hand-to-leg method and BIA leg-to-leg method in a sample of athletic individuals aged 7 to 18 years.METHODS: The survey included a total of 178 ice-hockey players aged 7 to 18 years. The proportion of body fat analysed by means of the BIA hand-to-leg method was measured by the Tanita BC-418 MA instrument. For the purposes of the BIA leg-to-leg method the Tanita BF-350 instrument was used (Tanita, Japan. Both instruments work at a frequency of 50 kHz.RESULTS: The percentage of body fat established by the BIA leg-to-leg method (M = 13.5%; SD = 4.8 indicated signifi cantly lower values of fat percentage than the values measured by the BIA hand-to-leg method (M = 17.1%; SD = 4.3. The overall diff erence represents an average value of 3.6% (standard mode; p < .001; d = 0.8. Regarding the monitored age categories the observed diff erences are in the range of 3.1–4.7% (p < .001; d = 0.7–1.2.CONCLUSION: The present study compares the proportions of body fat by means of the BIA leg-to-leg method and BIA hand-to-leg method in athletic boys aged 7 to 18 years. The results measured by the BIA leg-to-leg method signifi cantly undervalue the proportion of body fat in comparison with the BIA hand-to-leg method. The instrument factor and age factor represented signifi - cant variables infl uencing the results of the

Full Text Available Objectives: The aim of this paper is to test the infl uence of long-term application of the low-frequency magnetic fi elds in magnetotherapy and magnetostimulation on cortisol secretion in men. Materials and Methods: Patients were divided into three groups: 16 men underwent magnetotherapy and 20 men (divided into two groups underwent magnetostimulation. Magnetotherapy – 2 mT induction, 40 Hz, bipolar square wave, was applied for 20 min to lumbar area. Magnetostimulation (Viofor Jaroszyk, Paluszak, Sieroń (JPS system, M2P2 program was applied to 10 patients for 12 min each day. The third group (10 patients underwent magnetostimulation (Viofor JPS system, M3P3 for 12 min each day using a different machine. All groups had 15 rounds of applications at approximately 10:00 a.m. with intermissions on the weekends. Blood serum was taken four times in a 24-hour period, before applications, the day after applications and a month later. Chemiluminescence micromethod was used to indicate hormone concentrations. Data was statistically analyzed with the analysis of variance (ANOVA method. Results: The statistically signifi cant gains in the circadian cortisol profi le at 4:00 p.m., before and after application, were observed as a decrease in concentration during magnetotherapy. In magnetostimulation, with the M2P2 program, a signifi cant increase in the cortisol concentration was observed in circadian profi le at 12:00 p.m. one month after the last application. After magnetostimulation with the M3P3 program, a signifi cant increase in concentration at 6:00 a.m. and a decrease in concentration at 12:00 p.m. were observed one month later. Statistically signifi cant difference was demonstrated in the participants after the application of magnetotherapy and magnetostimulation with M3P3 program compared to the men submitted to magnetostimulation, with M2P2 program, at 4:00 p.m. after 15 applications. Conclusions: Biological hysteresis one month after

Full Text Available http://dx.doi.org/10.5007/1980-0037.2008v10n2p115 The body of the adolescent dancer is the result of morphological, physiological and behavioral adaptations due to specific physical training. For the ballet master, body weight is irrelevant to evaluating the technical and artistic performance and beauty of a figure. All ballet dancers must have bodies that conform to the canon of international ballet in order to be able to perform in public. The purpose of this study is to describe the changes in the body composition of dancers at the Cuban National School of Ballet between two points in their training process. This was a longitudinal study of 54 girls and 40 boys, aged between 15 and 20 years old. An anthropometric protocol of 6 measurements was employed in order to determine body composition using the Durnin and Rahaman method for females and the Parizková and Buzková method for males. The main results demonstrate signifi cant increases in both weight and height for age in both sexes, and it was observed that height growth velocity decreased with age. The female dancers exhibited stable body fat percentages for all ages while male dancers signifi cantly reduced this percentage from one year to the next. The female students exhibited higher mean percentage body fat values than the normal range established in Cuba for elite athletes from competitive artistic sports and professional dancers, while the male students exhibited body fat percentages that were similar to these specialized groups.

Full Text Available Objectives: The aim of the study was to make an international comparison of blood levels of cadmium (B-Cd, lead (BPb and mercury (B-Hg of women in seven European, and three non-European cities, and to identify determinants. Materials and Methods: About 50 women (age: 46–62 from each city were recruited (totally 480 in 2006–2009. Interview and questionnaire data were obtained. Blood samples were analysed in one laboratory to avoid interlaboratory variation. Results: Between the European cities, the B-Pb and B-Cd results vary little (range of geometric means: 13.5–27.0 μg/l and 0.25–0.65 μg/l, respectively; the variation of B-Hg was larger (0.40–1.38 μg/l. Between the non-European cities the results for B-Pb, B-Cd and B-Hg were 19.2–68.0, 0.39–0.99 and 1.01–2.73 μg/l, respectively. Smoking was a statistically signifi cant determinant for B-Cd, while fi sh and shellfi sh intakes contributed to B-Hg and B-Pb, amalgam fi llings also contributed to B-Hg. Conclusions: The present results confi rm the previous results from children; the exposure to lead and cadmium varies only little between different European cities suggesting that other factors than the living area are more important. The study also confi rms the previous fi ndings of higher cadmium and lead levels in some non-European cities. The geographical variation for mercury is signifi cant.

2009-05-01

We have investigated the magnetic and dielectric properties of Ca2CoSi2O7 crystal. The dielectricity and magnetism of Ca2CoSi2O7 are strongly coupled below a canted antiferromagnetic transition temperature (TN). Magnetic fields induce electric polarization below TN. Interestingly, the magnetic-field-induced electric polarization is detected even without poling electric fields. Below TN, a canted antiferromagnetic-paramagnetic transition is induced by magnetic fields. The large magnetocapacitance is observed around TN. The origin of the large magnetocapacitance is due to the magnetic-field-induced the canted antiferromagnetic-paramagnetic transition.

In coronary artery disease (CAD), body surface potential mapping (BSPM) may reveal minor electrical potential changes appearing in the depolarization phase even if pathological changes are absent on the conventional 12-lead ECG. We hypothesized that a simple BSPM parameter, Max/Min signifies successful percutaneous coronary intervention (PCI). Ninety-two adult Caucasian patients with stable CAD and positive exercise test underwent coronary angiography. Seventy patients (age, 59 ± 8; 46 males) were revascularized by PCI (left anterior descending [LAD] in 38, right [RCA] in 17 and left circumflex [LCX] coronary artery in 15). Control groups contained 22 patients (age, 60 ± 8; 14 males) without intervention and 35 healthy subjects (age, 58 ± 2; 15 males). Left ventricular ejection fraction (LVEF, transthoracic echocardiography) and Max/Min BSPM parameter (63-lead Montreal system) were evaluated before and 4-40 days following coronary angiography. Max/Min was defined by the ratio of the highest maximum to the deepest minimum potential of all leads recorded by BSPM. Before PCI, Max/Min value of patients with LAD lesion (0.83 [0.74; 0.93]) was significantly lower while that with RCA lesion (1.63 [1.35; 1.99]) was significantly higher than that of healthy group (1.01 [0.970; 1.13]) (P intervention. LVEF significantly increased (from 46.50% [43.00; 51.00] to 49.00% [46.00; 51.00]) only after LAD PCI. Max/Min parameter is suitable to follow patients after LAD and RCA PCI. © 2015 Wiley Periodicals, Inc.

Magnetization reversal in weak ferrimagnets and canted antiferromagnets

International Nuclear Information System (INIS)

Kageyama, H.; Khomskii, D.I.; Levitin, R.Z.; Markina, M.M.; Okuyama, T.; Uchimoto, T.; Vasil'ev, A.N.

2003-01-01

In some ferrimagnets the total magnetization vanishes at a certain compensation temperature T*. In weak magnetic fields, the magnetization can change sign at T* (the magnetization reversal). Much rarer is observation of ferrimagnetic-like response in canted antiferromagnets, where the weak ferromagnetic moment is due to the tilting of the sublattice magnetizations. The latter phenomenon was observed in nickel (II) formate dihydrate Ni(HCOO) 2 ·2H 2 O. The observed weak magnetic moment increases initially below T N =15.5 K, equals zero at T*=8.5 K and increases again at lowering temperature. The sign of the low-field magnetization at any given temperature is determined by the sample's magnetic prehistory and the signs are opposite to each other at T N

Full Text Available Background: Hepatocellular carcinoma is one of the most common cancers and a lethal disease. In view of the limited treatment and a grave prognosis of liver cancer, preventive control has been emphasized. Materials and Methods: The methanolic extract of roots of Cynodon dactylon was screened for its hepato-protective activity in diethyl nitrosamine (DEN induced liver cancer in Swiss albino mice. The plant extract at a dose of 50 mg/kg was administered orally once a week, up to 30 days after DEN administration. The animals were sacrificed; blood sample and liver tissue were collected and used for enzyme assay such as, asparatate amino transferase (AST, alanine aminotransferase (ALT, catalase (CAT, glutathione peroxidase (GPx and glutathione-S-transferase (GST. The liver marker enzymes AST and ALT produced signifi cant results in the protective action. Results: The antioxidant enzyme assay results concerning the improved activity of GPx, GST and CAT. These results concluded that enhanced levels of antioxidant enzyme and reduced amount of serum amino transaminase, which are suggested to be the major mechanisms of C. dactylon root extract in protecting the mice from hepatocarcinoma induced by DEN. These biochemical observations were supplemented by histopathological examination of liver sections. Conclusion: The methanolic extract of C. dactylon possesses signifi cant anticancer properties

Full Text Available As a symbolic function, the Ideal of the Revolution becomes the central signifier in the subjectivity of its militants, and creates its own Names of the Father, its own master signifiers that alienate the combatants and generate effects at the level of "the sacred" in the symbolic, imaginary, and real registers, in both the public setting of the collective and the private one of the subject. The objective of the article is to understand the deployment of the ideal that drives the revolutionary cause, the ways it operates in the collective and singular setting, and the effects it causes on subjectivity. Finally, it examines the process of downfall of the ideal and some of its dilemmas as a preamble of the subject's exit from war.

Ordered arrays of nanowires of pure SpFeMn(C 2 O 4 ) 3 collinear antiferromagnet have been synthesized in pores of anodized aluminum oxide (AAO) 20 nm and 200 nm in diameter. It was found that the growth of spin-canted phase presented in the bulk samples is suppressed in nanowires. The decrease in the nanowires diameter results in magneto-crystalline anisotropy increase. - Highlights: • The method for separation of two magnetic phases of SpFeMn(C 2 O 4 ) 3 was developed. • Nanowires of collinear antiferromagnet SpFeMn(C 2 O 4 ) 3 was synthesized in pores of AAO. • Suppression of canted phase presented in the bulk samples was found in nanowires. • Magnetic anisotropy indicates monocrystallinity of nanowires grown in AAO pores. • The decrease of nanowires diameter results in magnetocrystalline anisotropy increase

Full Text Available AIM: This study aimed at describing and comparing the kinetics of aerobic and anaerobic decomposition of Eleocharis interstincta, Nymphaea sp. and Montrichardia arborescens; METHODS: The samples of aquatic macrophytes and water were collected in the Cantá Stream (02° 49' 11" N and 60° 40' 24" W, Cantá, Roraima, Brazil. The plant material was dried and triturated and for each experimental condition (aerobic and anaerobic mineralization chambers were prepared with plant fragments and stream water. The volume of evolved gases in anaerobic mineralization was monitored during 78 days, while the oxygen consumption was measured for 121 days; RESULTS: The results of aerobic and anaerobic decomposition were fitted to first-order kinetics model. The oxygen consumption varied from 195.36 mg g-1 (DM for E. interstincta to 629.46 mg g-1 (DM for Nymphaea sp. The deoxygenation rate derived from mineralization of M. arborescens was higher (kD: 0.049 day-1, followed by E. interstincta (kD: 0.038 day-1 and Nymphaea sp. (kD: 0.027 day-1. For the anaerobic condition the evolution of gases presented two phases: the consumption and formation. According to temporal variations of mineralized carbon, the anaerobic decomposition of M. arborescens presents the higher mineralization coefficient (0.0047 day-1; followed by Nymphaea sp. (0.0035 d-1 and E. interstincta (0.0017 day-1; CONCLUSION: Based on these results we conclude that during the aerobic decomposition of these macrophytes, the Nymphaea sp. was responsible for the higher oxygen demand and M. arborescens generated the highest amounts of gases during the anaerobic mineralization. On average, the aerobic decay processes were 11-fold faster than anaerobic. Regarding to the materials fluxes in freshwater ecosystems, low rate of decomposition observed in anaerobic process when comparing to aerobic rates reflect that the sediment represent a very efficient sink of carbon in the organic matter cycling

Full Text Available When we project an emotional charge onto an object, this turns into a thing that refers to ourselves, and allows the subject to know himself/herself better. In this study, the relationship between a black doll called Gorogó and the characters of Ana María Matute’s Primera Memoria will be analyzed in order to glimpse the signified that the signifier Gorogó acquires through its displacements. Following Lacan’s postulates, it is possible to determine three positions of the doll. When it remains hidden, it confers a certain protection to the protagonist. When it is revealed and enters in a relationship with the other characters, it causes an odd sensation (unheimlich, for being a thing that had to be kept unseen and that has been revealed. At the end, Gorogó stands out for his absence and reveals the temporal dimension of things, namely, the protagonist’s growth and the internal conflict that this entails.

A 2D rhomboidal system of manganese(ii) [Mn(3-MeC6H4COO)2(H2O)2]n with spin canting: rationalization of the magnetic exchange.

Garcia-Cirera, Beltzane; Costa, Ramon; Moreira, Ibério de P R; Font-Bardia, Mercè; Corbella, Montserrat

2018-03-12

The crystal structure of Mn(ii) carboxylate with 3-methylbenzoate as a bridging ligand [Mn(3-MeC 6 H 4 COO) 2 (H 2 O) 2 ] n shows a rhomboidal layer, where each pair of neighbor Mn(ii) ions are bridged through only one carboxylate group with a syn-anti conformation. The magnetic exchange between neighbor ions is weakly antiferromagnetic (J = -0.52 cm -1 , g = 2.04), and at low temperature the system shows spin canting with T B = 3.8 K. Computational studies, based on periodic calculations of the energies of the significant spin states on the magnetic cell and some higher supercells, corroborate the weak AF interaction between the adjacent Mn(ii) ions and preclude the negligible effect of frustration caused by very weak interactions between the non-adjacent ions in the magnetic response of the system. The results provide compelling evidence that the observed spin canting is due to the local coordination geometry of the manganese ions leading to two antiferromagnetically coupled subnets with different axial vectors.

Full Text Available Epilepsy is one of the most common neurological disorders, characterized by recurrent seizures, which may increase the content of reactive oxygen and nitrogen species. Th e objective of this study was to investigate the eff ects of Neuropeptide Y on oxidative and nitrosative balance and brain-derived neurotrophic factor levels induced by pentylenetetrazole (a standard convulsant drug in the hippocampus of Wistar rats. Th ree groups of seven rats were treated intraperitoneally as follows: group  (saline + saline  ml saline, group  (salin + Pentylenetetrazole  ml saline  min before Pentylenetetrazole; and group  (Neuropeptide Y + Pentylenetetrazole  μg/kg Neuropeptide Y  min before  mg/kg Pentylenetetrazole. After  h, the animals were euthanized by decapitation. Hippocampus were isolated to evaluate the malondialdehyde, glutathione, nitric oxide, and brain-derived neurotrophic factor levels in three rat groups. Th e results of this study demonstrated that while intraperitoneally administered neuropeptide Y did not result in a statistically signifi cant diff erence in BDNF levels, its administration caused a statistically signifi cant decrease in malondialdehyde and nitric oxide levels and an increase in glutathione levels in rats with pentylenetetrazole-induced epileptic seizure. Neuropeptide Y were able to reduce nitroxidative damage induced by pentylenetetrazole in the hippocampus of Wistar rats.

There was a statistically signifi cant difference between the carboxyhemoglobin levels of the patients according to the clinical classifi cation (p<0.05. The intoxication caused by heaters was observed signifi cantly in November, December and January (p<0.001, between 16:00-24:00 hours (p<0.001 and among more than one member of a family (p<0.001. A medium level correlation was detected between the treatment approach and clinical classifi cation (r=0.50, p<0.001. Conclusion: Carbon monoxide intoxication, in the presented series, was found to develop accidentally; mostly in the Winter season; during night hours when the family members gathered together. The carboxyhemoglobin levels were appropriate with the developing clinical findings. Carboxyhemoglobin level solely was not enough for achieving the diagnosis and planning the treatment.

Prisoners signify: a political discourse analysis of mental illness in a prison control unit.

Science.gov (United States)

Cloyes, Kristin Gates

2007-09-01

Increasingly, US prisoners diagnosed with mental illness are housed in control units, the most restrictive form of confinement in the US prison system. This situation has led to intense debate over the legal, ethical and clinical status of mental illness. This is a semiotic struggle with profound effects, yet most related work treats mental illness as a neutral, individual variable. Few analyses locate mental illness within a larger sociopolitical context. Fewer still focus on discursive practice. None critically analyze the accounts of control unit prisoners, who talk about extreme marginality and risk for victimization. This paper has two aims: (i) to develop a systematic method of analysis that accounts for signification as discourse-in-action; and (ii) to show how prisoners' signification of mental illness articulates agency through and against marginalizing discourse. Political discourse analysis demonstrates how control unit prisoners with psychiatric diagnoses signify mental illness, and articulate safer identifications in the process.

We present a theory for surface polaritons on ferroelectric-antiferromagnetic materials with canted spin structure. A small uniform canted moment is allowed, resulting in a weak ferromagnetism directed in the plane parallel to the surface. Surface and bulk polariton modes for a semi-infinite film are calculated for the case of transverse electric (TE) and transverse magnetic (TM) polarization. Example results are presented using parameters appropriate for BaMnF{sub 4}. We find that the surface modes are non-reciprocal for the TE polarization due to the magnetoelectric interaction, and the non-reciprocity can be controlled by an applied electric field. Example results for attenuated total reflection (ATR) are calculated. The magnetoelectric interaction also gives rise to 'leaky' surface modes in the case of TM polarization. These are pseudo-surface waves that exist in the pass band, and dissipate energy into the bulk of the material. We show that these pseudo-surface mode frequencies and properties can be modified by temperature and the application of external electric or magnetic fields.

Alternating-gradient canted cosine theta superconducting magnets for future compact proton gantries

Directory of Open Access Journals (Sweden)

Full Text Available We present a design of superconducting magnets, optimized for application in a gantry for proton therapy. We have introduced a new magnet design concept, called an alternating-gradient canted cosine theta (AG-CCT concept, which is compatible with an achromatic layout. This layout allows a large momentum acceptance. The 15 cm radius of the bore aperture enables the application of pencil beam scanning in front of the SC-magnet. The optical and dynamic performance of a gantry based on these magnets has been analyzed using the fields derived (via Biot-Savart law from the actual windings of the AG-CCT combined with the full equations of motion. The results show that with appropriate higher order correction, a large 3D volume can be rapidly scanned with little beam shape distortion. A very big advantage is that all this can be done while keeping the AG-CCT fields fixed. This reduces the need for fast field ramping of the superconducting magnets between the successive beam energies used for the scanning in depth and it is important for medical application since this reduces the technical risk (e.g., a quench associated with fast field changes in superconducting magnets. For proton gantries the corresponding superconducting magnet system holds promise of dramatic reduction in weight. For heavier ion gantries there may furthermore be a significant reduction in size.

The floating signifier “talent” in talent management - and why talent management has become a religion

DEFF Research Database (Denmark)

Adamsen, Billy

Within business life the term “talent” has been used by business leaders and consultants for decades to describe upcoming business managers with certain gifts and skills. Within science, especially within talent management, “talent” has been the fulcrum of most research and most research questions...... “talent” has changed semantically, and transformed itself into a floating signifier, and through its multiplicity of meaning, has turned the discipline of talent management into a religion, where believing seems to be more prevalent than knowing. The consequences of talent management being a religion...... have had - for years - focused on how the environment, culture, psychology and competencies influence the “talent”. To a certain extent science today can explain how certain internal and external variables can influence the development and the performance of a “talent”, but they are still unable...

Membrane-bound HLA-G (mHLA-G) discovery on adipose derived stem cells (ADSCs) as a tolerogenic and immunosuppressive molecule was very important. Many documents have shown that HLA-G expression can be controlled via some hormones such as progesterone (P4) and estradiol (E2). Therefore, this study was designed to evaluate progesterone and estradiol effects on mHLA-G in ADSCs at restricted and combination concentrations. Three independent cell lines were cultured in complete free phenol red DMEM and subcultured to achieve suffi cient cells. These cells were treated with P4, E2 and P4 plus E2 at physiologic and pregnancy concentrations for 3 days in cell culture conditions. The HLA-G positive ADSCs was measured via monoclonal anti HLA-G-FITC/MEMG-09 by means of flow cytometry in nine groups. Data were analyzed by one way ANOVA and Tukey's post hoc tests. There were no signifi cant values of the mean percentage of HLA-G positive cells in E2-treated and the combination of P4 plus E2-treated ADSCs compared to control cells (p value>0.05) but P4 had a signifi cant increase on mHLA-G in ADSCs (p value<0.05). High P4 concentration increased mHLA-G but E2 and the combination of P4 plus E2 could not change mHLA-G on ADSCs.

Background: Growth abnormalities are uniquely associated with autism spectrum disorders (ASD); however, the extent to which growth abnormalities are present has hardly been investigated. The current study aims to compare the differences in anthropometric parameters in a group of autistic Egyptian children and the healthy normal population. Methods: We recruited 100 children with ASD from the Outpatient Clinic for "Autistic Children" at the Medical Research Hospital of Excellence, National Research Centre in Cairo, Egypt. They were diagnosed by DSM-IV criteria of the American Psychiatric Association, Autism Diagnostic Interview-Revised, and Childhood Autism Rating Scale. Of these children at age of 3-10 years, 71 were males and 29 females. Eight anthropometric parameters were assessed in view of data of the healthy Egyptians of pertinent sex and age. Results: Weight and body mass index increased because of a signifi cant increase in subcutaneous fat thickness. This tendency with a probable decrease in muscle mass was more evident in male or in older children, likely resulting from sedentary life style and food selectivity. Conclusions: The Z head circumference score and its variance signifi cantly increased especially in males or older children, suggesting the relative overgrowth of the brain in a substantial percentage of Egyptian children with autism. We concluded that increased fat composition in Egyptian autistic children with decreased muscle mass necessitates tailoring a specially designed food supplementation program to ameliorate the severity of autism symptoms.

The purpose of the present study was to analyze the acute effects of the green coffee extracts consumption in some biomarkers of adult Brazilian subjects. Twenty healthy adult subjects between 18 and 35 years old of different sex and ethnic groups took part in the present study. All participants were submitted a 12 hours overnight fast before experiments. Plasma and serum biochemical parameters were measured in distinct intervals after a breakfast standard ingestion and 0.6 L of green coffee been extract consumption. No statistically differences (Wilcoxon test on serum lipid profi le and plasmatic homocysteine concentration were noted after green coffee beverage intake. Caffeine has been associated with increase of the glycaemia in roasted coffee consumers. In the present study, a signifi cant increase (p= 0.03 in glycaemia was observed thirty minutes after the green coffee beverage ingestion and, then, there was a tendency of glycaemia maintenance. The low amount of free caffeine found in green coffee matrix could explain the quick stabilization of the glycaemia. The ingestion of green coffee beverage also signifi cantly reduced uricaemia (p= 0.03 (Wilcoxon test. It is possible that the polyphenols, present in high amounts in this beverage, could act inhibiting the xanthine oxidase enzyme. Therefore, the consumption of green coffee has to stabilize blood glucose 30 minutes after ingestion of test meal, and reduction of uricaemia.

Las excavaciones arqueológicas llevadas a cabo en yacimientos de la importancia de La Coruña, Gijón, Santander, Castro Urdíales y el área del Bajo Bidasoa aportan continuos datos sobre el desarrollo urbano y comercial de estos núcleos. En nuestra opinión, debemos contemplar los establecimientos litorales cantábricos dentro de una dinámica histórica y económica de carácter regional, en cuyo desarrollo desempeñaron un papel de primer orden tanto las vías de comunicación terrestres como la ruta marítima. En el estado actual de la investigación parece evidenciarse un desarrollo ligeramente más temprano de los asentamientos de la zona oriental (Pais Vasco y Cantabria, aunque el auténtico despegue de la franja cantábrica tiene lugar a partir de época flavia. Desde finales del siglo I d. C, la documentación arqueológica muestra una evolución muy semejante en toda la región, que continúa, aparentemente sin interrupción, hasta el siglo VI d.

Full Text Available The meaning of technology transfer is so wide but mostly involving some form of technology-re- lated exchange. However, in this particular paper, technology transfer is consider as a concept to examine the process of disseminating knowledge and skills that a person owned to another per- son in order to generate higher productivity with new approach of producing a particular prod- uct or service. Although, many researchers have explored the evolution of technology transfer, nonetheless some drivers are yet to be explored in a Malaysian manufacturing industry. This study, therefore attempts to determine the relationship between absorptive capacity, transfer capacity, communication motivation and learning intent and technology transfer performance. A survey methodology was used in a Japanese multinational company based in Klang Valley, Malaysia. A total of 117 questionnaires were received. Results show that absorptive capacity is the most signifi- cant to influence technology transfer performance.

Teenage pregnancy is a signifi cant social issue in the United States, resulting in increased levels of poverty. Most public health family planning efforts have traditionally focused on teaching teens the how-to of contraception, with little focus on teaching the why-to. During my time as a nurse practitioner in a public health department family planning clinic, I developed a method to open discussions with patients about the possibilities of a future that includes delayed childbearing. My experience with this strategy taught me that hope may indeed be the most powerful contraceptive of all.

Full Text Available Considerar o termo "infância" como um "significante sempre em falta de significação" permite-nos uma rede argumentativa sustentada no discurso psicanalítico, segundo a perspectiva de Giorgio Agamben, que coloca a infância em relação à linguagem. Ponto de partida para fazer a seguinte tese: A infância - como significante - é, para a linguagem, o que o desejo é para a lei. Infância foi, é e será um significante sempre em falta de significação, instituindo-se pela linguagem e no campo da linguagem. O estatuto da legalidade subjetiva deve distinguir-se do código jurídico para poder colocar a tensão possível entre um e outro. É preciso esclarecer o sentido que damos ao termo instituição, distinguindo-o do sentido jurídico que ele recebeu e ainda conserva, propondo recuperar seu valor em termos de escritura da lei na constituição subjetiva, marco epistêmico que nos brinda a psicanálise.Considering the term "childhood" as a "signifier always lacking signification" enables us to establish an argumentative network supported by the psychoanalytical discourse. According to Giorgio Agamben, childhood is related to language, and this is the starting point for the following thesis: childhood - as a signifier - stands for language as desire stands for law. It was, is and will be a signifier always in lack of signification, establishing itself by language and in the field of language. The statute of the subjective legality must be distinguished from the judicial code enabling the enactment of a possible tension between them. The meaning given to the term institution must be cleared up: it should be distinguished from the legal sense it has been given and still retains, proposing a retrieval of its value in terms of the writing of law as subjective constitution, an epistemic landmark raised by psychoanalysis.

Signifying quantum benchmarks for qubit teleportation and secure quantum communication using Einstein-Podolsky-Rosen steering inequalities

Science.gov (United States)

Reid, M. D.

2013-12-01

The demonstration of quantum teleportation of a photonic qubit from Alice to Bob usually relies on data conditioned on detection at Bob's location. I show that Bohm's Einstein-Podolsky-Rosen (EPR) paradox can be used to verify that the quantum benchmark for qubit teleportation has been reached, without postselection. This is possible for scenarios insensitive to losses at the generation station, and with efficiencies of ηB>1/3 for the teleportation process. The benchmark is obtained if it is shown that Bob can “steer” Alice's record of the qubit as stored by Charlie. EPR steering inequalities involving m measurement settings can also be used to confirm quantum teleportation, for efficiencies ηB>1/m, if one assumes trusted detectors for Charlie and Alice. Using proofs of monogamy, I show that two-setting EPR steering inequalities can signify secure teleportation of the qubit state.

Full Text Available An interspecific factorial hybridization was made, where seven P. strobus female parent trees were mated to four P. wallichiana male trees, in order to transfer genes for resistance to blister-rust from the blue pine to the F1 hybrids. The hybrid seedlings and the open pollinated families of the two parents were three times consecutively inoculated with blister-rust. The six years old seedlings were transplanted in the fi eld in the so called Valiug Experiment 1. The experimental design consisted in 28 hybrid full-sib families and two open pollinated families of the parent species. Plantation took place in a complete randomized block design with three blocks, with 6 to 12 seedlings per linear plot and 3 x 3 m spacing. This paper is based on the measurements made at age 32, just after the fi rst thinning. Diameter at breast height, tree height, tree volume, stem straightness and tree survival were the fi ve measured traits. According to ANOVA, signifi cant (p < 0.05 and highly signifi cant (p < 0.001 differences for diameter at breast height, tree height, volume growth rate, stem straightness and tree survival were detected between hybrid families. Highly signifi cant (p< 0.01, p < 0.001 differences were found between eastern white pine female parents for survival, stem straightness and all growth traits, suggesting that nuclear additive genes are controlling the respective characters. Consequently, high survival or genetic resistance to blister-rust can be found within the P. strobus species even though it is highly susceptible to this pathogen. The P. wallichiana parents exhibited signifi cant additive effects on straightness and breast height diameter, but no signifi cance in height, volume, and tree survival. The contribution of the additive variance to the phenotypic one was 65.7% for diameter, 58.6% for height, 50.5% for volume, 70.4% for stem straightness and 73.4% for tree survival. Hence, additive variance should be employed

2017-12-01

The self-interstitial carbon is the key to radiation damage in graphite moderator nuclear reactor, so an understanding of its behavior is essential for plant safety and maximized reactor lifetime. The density functional theory is applied on four different graphite unit cells, starting from of 64 carbon atoms up to 256 carbon atoms, using AIMPRO code to obtain the energetic, athermal and mechanical properties of carbon interstitial in graphite. This study presents first principles calculations of the energy of formation that prove its high barrier to athermal diffusion (1.1 eV) and the consequent large critical shear stress (39 eV-50 eV) necessary to shear graphite planes in its presence. Also, for the first time, the gamma surface of graphite in two dimensions is calculated and found to yield the critical shear stress for perfect graphite. Finally, in contrast to the extensive literature describing the interstitial of carbon in graphite as spiro interstitial, in this work the ground state of interstitial carbon is found to be canted spiro interstitial.

Full Text Available Background and Aim: There are evidences that indicate a relationship between auditory processing disor¬ders and stuttering,¬ and any disorder in the central auditory function can be at least one of the underly¬ing causes of stuttering. Even though, using the most state of the art radiographic technologies, i.e. MRI, no definitive answer has been given in relative to this question. In this research, using Mask-ing Level Difference (MLD and Synthetic Sentence Identification (SSI tests, the central auditory func¬tion of stutters and normal group was evaluated.Materials and Methods: In this study was analytic cross-sectional, fifteen male patients with stutter-ing and 15 male normal cases with the age range from 16 to 40 years (average age 26.78 year were evalu¬ated. SSI-ICM, SSI-CCM and MLD tests were performed. The results were compared in both groups.Results: Although stutterers mean MLD was less than that of normal group, the different was not signifi¬cant between stutters and normal group in SSI test in right ear at negative MCRs. There was a signifi¬cant difference in ICM state, but in CCM state, there was no significant difference between the aver¬age score of two groups in various MCRs.Conclusion: The findings of this research is compatible with those of similar researches about the SSI test and the pattern of results, probably indicates a partial dysfunction of brainstem in some of the stutters.

Full Text Available http://dx.doi.org/10.5007/1980-0037.2008v10n2p155 The Patellofemoral pain syndrome (PFPS is described as an anterior or retropatellar knee pain in the absence of other associated diseases, and has often been associated with dysfunction of the vastus medialis oblique muscle (VMO. However, several studies have demonstrated the impossibility of selectively activating this muscle with exercises. The aim of the present study was to analyze the immediate effect of neuromuscular electrical stimulation of VMO muscle by means of monitoring the electromyographic activity of the vastus medialis oblique (VMO and vastus lateralis (VL muscles. Eighteen healthy women with a mean age of 23.2 years and mean BMI of 20 Kg/m2 were evaluated. The study protocol included electromyographic analysis of VMO and VL muscles, before and immediately after neuromuscular electrical stimulation of the VMO muscle. During the electromyographic analysis, the volunteers performed maximal voluntary isometric contraction in a 60° knee extension on an isokinetic dynamometer. “Russian current” apparatus was used for electrical stimulation. Results: The data analysis demonstrated a signifi cant increase in VMO activation intensity immediately after it had been electrically stimulated (p=0.0125, whereas VL activation intensity exhibited no signifi cant increase (p=0.924. Moreover, a significant increase in the VMO/VL ratio was also detected (p=0.048. In this study it was observed that electrical stimulation modifiedthe VMO/VL ratio, which suggests electrical stimulation has a benefi cial effect on VMO muscle strength.

Full Text Available Introduction: Legislation systems of most countries prohibited using the handheld mobile phone while driving due to the fact that it disturbs concentration and causes hand involvement. Every phone owner is accustomed to the ringtone of his phone and almost involuntarily endeavors to pick it up or check who calls. This engages one’s psychomotor skills, which in our opinion contributes to the attenuation of reaction time needed for performing other crucial functions. Objectives: The aim of the study was: (1 to evaluate the infl uence of the sound of a ringing mobile phone on the complex reaction time (RT score in healthy subjects (owners, and (2 to check if there are any differences in RT when a landline phone and mobile phone ring. Methods: To assess RT we used our system and protocol of examination, previously validated. The examination conditions were standardized. All tests were performed in the same room with the same light and general acoustic conditions. The test group consisted of 23 women and 24 men, aged 19–24 years. The examination comprised 4 sessions: Training Session (TS during which the subjects were accustomed with the application and sample stimuli, Control Session (CS with no telephone ringing, Landline Session (LS with landline phone ringing, Mobile Session (MS with mobile phone ringing. Results: The median RT in the study population was signifi cantly elongated (p 0.05. Conclusions: We think that the specifi c ‘bond’ between a person and their private phone can signifi cantly disrupt their attention and thus affect the attention-demanding activities.

Quien quiera que tenga que estudiar arte prehistórico ha de partir forzosamente de lo establecido por Breuil, teniendo en cuenta que si es fácil mejorar alguna de sus conclusiones, es mucho más difícil corregirlas o enmendarlas. Por eso a nadie ha de extrañar que si nuestras investigaciones parten de los resultados obtenidos por Breuil, nuestro esbozo de un nuevo sistema para el arte paleolítico de la región cantábrica no sea más que una ampliación de sus ideas, a la que hemos añadido unas nuevas conclusiones, fruto de nuestros trabajos, que creemos mejoran y perfeccionan el sistema del llorado maestro.

Full Text Available The relation between crop growing and soil tillage treatment are play important role in agricultural production. Soils under conventional tillage (CT generally have lower bulk density and associated higher total porosity within the plough layer than under no tillage (NT. No-till farming can reduce soil erosion, conserve soil moisture and minimize labor and fuel consumption. The aim of this study were to investigate the effects of conventional, reduced and notillage methods on soil physical properties, sunfl ower yield and yield components, protein and oil content and fuel consumption in Southeastern of Turkey. Six tillage methods for the second crop sunfl ower were tested and compared each other within after lentil harvesting at 2003 and 2004 years in a clay loam soil. According to results, the fi rst year, the bulk density had decreased from 1.29 to 1.09 g cm-3, the second year the δb had decreased from 1.41 to 1.23 g cm-3. Differences between years and tillage methods in terms of yield were found signifi cant (p<0.05. However, no differences were found between the NT and CT. There were also no signifi cance differences in content of protein, oil and ash among six tillage methods. The highest fuel consumption was measured in conventional method (CT whereas the lowest value was found in direct seeding method as 33.48 L ha-1 and 6.6 L ha-1, respectively.

The performance of three kinds of masks: pre-mask, splitter mask and fixed mask-photon shutter, used for the first canted-undulator front end under heat loads at SSRF, is studied. Because these components are shared with two beamlines, the X-rays from both dual undulators and bending magnets can strike on them. Under these complicated conditions, they will absorb much more thermal power than when they operate in usual beamline. So thermal and stress analysis is indispensable for their mechanical design. The method of applying the non-uniform power density using Ansys is presented. During thermal stress analysis, the normal operation or the worst possible case is considered. The finite element analyses results, such as the maximum temperature of the body and the cooling wall and the maximum stress of these components, show the design of them is reasonable and safe.

Background. Stereotactic radiation therapy is an evolving modality to treat otherwise unresectable liver metastases. In this analysis, two local therapies: 1) single session robotic radiosurgery (RRS) and 2) percutaneous radiofrequency ablation (RFA) were compared in a total of 60 heavily pretreated colorectal cancer patients. Methods. Thirty patients with a total of 35 colorectal liver metastases not qualifying for surgery that were treated in curative intent with RRS were prospectively followed. To compare efficacy of both treatment modalities, patients treated with RFA during the same period of time were matched according to number and size of the treated lesions. Local tumor control, local disease free survival (DFS), and freedom from distant recurrence (FFDR) were analyzed for effi cacy. Treatment-related side effects were recorded for comparison. Results. The median diameter of the treated lesions was 33 mm (7-53 mm). Baseline characteristics did not differ significantly between the groups. One- and two-year local control rates showed no signifi cant difference but favored RRS (85% vs. 65% and 80% vs. 61%, respectively). A signifi cantly longer local DFS of patients treated with RRS compared to RFA (34.4 months vs. 6.0 months; p 0.001) was found. Both, median FFDR (11.4 months for RRS vs. 7.1 months for RFA p=0.25) and the recurrence rate (67% for RRS and 63% for RFA, p>0.99) were comparable. Conclusion. Single session RRS is a safe and effective method to treat colorectal liver metastases. In this analysis, a trend towards longer DFS was seen in patients treated with RRS when compared to RFA.

Hahn, M.; Walton, R.

2007-01-01

Common wood-nymph butterfl ies are found throughout the United States and Canada. However, not much is known about how they overwinter or their preferences for particular grasses and habitats. In this study, the impact of prairie management plans on the abundance of the wood-nymph population was assessed, as well as the preference of these butterfl ies for areas with native or non-native grasses. The abundance of common wood-nymph butterfl ies was determined using Pollard walks; more common wood-nymph butterfl ies were found in the European grasses than were found in the burned and unburned prairie sites. The majority of the vegetation at each of the three sites was identifi ed and documented. Using a 1 X 3 ANOVA analysis, it was determined there were signifi cantly more butterfl ies in the European grasses than in the burned and unburned prairie sites (p < 0.0005). There was no signifi cant difference between the burned and unburned treatments of the prairie on the common wood-nymph population. A multiple variable linear regression model described the effect of temperature and wind speed on the number of observed common wood-nymph butterfl ies per hour (p = 0.026). These preliminary results need to be supplemented with future studies. Quadrat analysis of the vegetation from all three sites should be done to search for a correlation between common wood-nymph butterfl y abundance per hour and the specifi c types or quantity of vegetation at each site. The effect of vegetation height and density on the observer’s visual fi eld should also be assessed.

Full Text Available It is shown that the Arab Spring acted as a trigger for a global wave of socio-political destabilization, which signifi cantly exceeded the scale of the Arab Spring itself and affected absolutely all world-system zones. Only in 2011 the growth of the global number of largescale anti-government demonstrations, riots and political strikes was to a high degree (although not entirely due to their growth in the Arab world. In the ensuing years, the Arab countries rather made a negative contribution to a very noticeable further increase in the global number of large-scale anti-government demonstrations, riots and general strikes (the global intensity of all these three important types of socio-political destabilization continued to grow despite the decline in the Arab world. Thus, for all these three important indicators of sociopolitical destabilization, the scale of the global echo of the Arab Spring has overshadowed the scale of the Arab Spring itself. Only as regards the fourth considered indicator (major terrorist attacks / guerrilla warfare the scale of the global echo for the entire period considered did not overshadow the scale of the Arab Spring (and, incidentally, «Winter» - and in 2014-2015 Arab countries continued to make a disproportionate contribution to the historically record global values of this sad indicator – global number of major terrorist attacks/ guerilla warfare. To conclude, triggered by the Arab Spring, the global wave of socio-political destabilization led after 2010 to a very signifi cant growth of socio-political instability in absolutely all World System zones. However, this global destabilization wave manifested itself in different World System zones in different ways and not completely synchronously.

Full Text Available Objectives: The main goal of the study was to assess possible association between fetal exposure to fi ne particulate matter (PM2.5 and exhaled carbon monoxide (eCO measured in non-asthmatic children. Material and Methods: The subjects include 118 children taking part in an ongoing population-based birth cohort study in Kraków. Personal samplers of PM2.5 were used to measure fi ne particle mass in the fetal period and carbon monoxide (CO in exhaled breath from a single exhalation effort at the age of 7. In the statistical analysis of the effect of prenatal PM2.5 exposure on eCO, a set of potential confounders, such as environmental tobacco smoke (ETS, city residence area, sensitization to house dust allergens and the occurrence of respiratory symptoms monitored over the seven-year follow-up was considered. Results: The level of eCO did not correlate with the self-reported ETS exposure recorded over the follow-up, however, there was a positive signifi cant relationship with the prenatal PM2.5 exposure (non-parametric trend p = 0.042. The eCO mean level was higher in atopic children (geometric mean = 2.06 ppm, 95% CI: 1.58–2.66 ppm than in non-atopic ones (geometric mean = 1.57 ppm, 95% CI: 1.47–1.73 ppm and the difference was statistically signifi cant (p = 0.036. As for the respiratory symptoms, eCO values were associated positively only with the cough severity score recorded in the follow-up (nonparametric trend p = 0.057. In the nested multivariable linear regression model, only the effects of prenatal PM2.5 and cough severity recorded in the follow-up were related to eCO level. The prenatal PM2.5 exposure represented 5.1%, while children’s cough represented only 2.6% of the eCO variability. Conclusion: Our study suggests that elevated eCO in non-asthmatic children may result from oxidative stress experienced in the fetal period and that heme oxygenase (HO activity in body tissues may be programmed in the fetal period by the exposure to

Hussain, Muhammad Mustafa

2011-02-01

The impact of contact materials on the performance of nanostructured devices is expected to be signifi cant. This is especially true since size scaling can increase the contact resistance and induce many unseen phenomenon and reactions that greatly impact device performance. Nanowire and nanoelectromechanical switches are two emerging nanoelectronic devices. Nanowires provide a unique opportunity to control the property of a material at an ultra-scaled dimension, whereas a nanoelectromechanical switch presents zero power consumption in its off state, as it is physically detached from the sensor anode. In this article, we specifi cally discuss contact material issues related to nanowire devices and nanoelectromechanical switches.

Full Text Available Fusarium wilt of watermelon (Citrullus lanatus caused by Fusarium oxysporum f. sp. niveum is a devastatine soil-borne disease that causes extensive losses throughout the world. Two known Pseudomonas biocontrol strains were used separately and in combination to assess their antagonistic effectiveness against F. oxysporum f. sp. niveum in pot experiments. P. chlororaphis PCL1391 signifi cantly reduced disease severity. P. fl uorescens WCS365 was less effective in disease suppression, while a combination of the two bacteria had intermediate effects. The biological control of Fusarium wilt with P. chlororaphis offers a potentially useful tool in an integrated pest management program to control Fusarium wilt of watermelon.

Highlights: • Cr(IV) ions are antiferromagnetically coupled within chains in ACrF{sub 5} (A = Cs, Rb, K). • Small structural difference causes huge difference in magnetic properties below 10 K. • Canted antiferromagnetism has been observed in RbCrF{sub 5} and KCrF{sub 5} at low temperature. - Abstract: In ACrF{sub 5} (A = Cs, Rb, K), Cr(IV) ions are coordinated by six fluoride ligands where the resulting CrF{sub 6} octahedra share cis vertexes to form infinite chains of ([Cr{sup IV}F{sub 5}]{sup −}){sub n}. The geometry of the latter in Cs compound differs from that in K and Rb compounds. The results of investigations of the magnetic behaviour of these compounds have shown that an antiferromagnetic superexchange interaction is present within the chains with J{sub Cs} = −10.2 cm{sup −1}, J{sub Rb} = −13.3 cm{sup −1}, and J{sub K} = −13.1 cm{sup −1}. Additional ferromagnetic-like long-range ordering has been observed in KCrF{sub 5} and RbCrF{sub 5} below 6 K which can be explained, in a correlation with their crystal structures, as canted antiferromagnetism.

Using spin-polarized scanning tunneling microscopy and density functional theory we demonstrate the occurrence of a novel type of noncollinear spin structure in Rh /Fe atomic bilayers on Ir(111). We find that higher-order exchange interactions depend sensitively on the stacking sequence. For fcc-Rh /Fe /Ir (111 ) , frustrated exchange interactions are dominant and lead to the formation of a spin spiral ground state with a period of about 1.5 nm. For hcp-Rh /Fe /Ir (111 ) , higher-order exchange interactions favor an up-up-down-down (↑↑↓↓) state. However, the Dzyaloshinskii-Moriya interaction at the Fe /Ir interface leads to a small angle of about 4° between adjacent magnetic moments resulting in a canted ↑↑↓↓ ground state.

The functional polymer (PMA-co-MAA) latex microspheres were used as a core template to prepare magnetic hollow spheres consisting of CoFe{sub 2}O{sub 4}/SiO{sub 2} composites. The spinel type crystal structure of CoFe{sub 2}O{sub 4} ferrite is formed under annealing, whereas the polymer cores are completely removed after annealing at 450 °C. Magnetic and Mössbauer spectroscopy measurements reveal very interesting magnetic properties of the CoFe{sub 2}O{sub 4}/SiO{sub 2} hollow spheres strongly dependent on the particle size which can be tuned by the annealing temperature. In the ground state of low temperatures, the CoFe{sub 2}O{sub 4} nanoparticles are in antiferromagnetic state due to the canted magnetic structure. Under heating in the applied field, the magnetic structure gradually transforms from canted to collinear, which increases the magnetization. The Mössbauer data revealed that the small size CoFe{sub 2}O{sub 4}/SiO{sub 2} particles (2.2–4.3 nm) do not show superparamagnetic behavior but transit from the magnetic to the paramagnetic state by a jump-like magnetic transition of the first order This effect is a specific property of the magnetic nanoparticles isolated by inert material, and can be initiated by internal pressure creating at the particle surface. The suggested method of synthesis can be modified with various bio-ligands on the silane surface, and such materials can find many applications in diagnostics and bio-separation. - Highlights: • CoFe{sub 2}O{sub 4}/SiO{sub 2} nanocomposites in shell of hollow microcapsules designed for biomedical applications • The CoFe{sub 2}O{sub 4} particle size and magnetic properties can be tuned by thermal treatment • Canted spin structure in the CoFe{sub 2}O{sub 4} nanoparticles coated by SiO{sub 2} • The first order magnetic transition in the CoFe{sub 2}O{sub 4} nanoparticles coated by silica.

Three Canted Radiator Panels to Provide Adequate Cooling for Instruments on Slewing Spacecraft in LEO

Science.gov (United States)

Choi, Michael K.

2012-01-01

Certain free-flying spacecraft in low Earth orbit (LEO) or payloads on the International Space Station (ISS) are required to slew to point the telescopes at targets. Instrument detectors and electronics require cooling. Traditionally a planar thermal radiator is used. The temperature of such a radiator varies significantly when the spacecraft slews because its view factors to space vary significantly. Also for payloads on the ISS, solar impingement on the radiator is possible. These thermal adversities could lead to inadequate cooling for the instrument. This paper presents a novel thermal design concept that utilizes three canted radiator panels to mitigate this problem. It increases the overall radiator view factor to cold space and reduces the overall solar or albedo flux absorbed per unit area of the radiator.

Nanoparticles of NixZn1-xFe2O4(x=0.0, 0.5 and 1.0) have been synthesized via co-precipitation method and studied thestructural and magnetic properties. Rietveld refinement of X ray diffraction data of as synthesized samples revealthat the samples have mixed spinel structure with space group Fd-3m. The lattice parameter of the samples decreases as doping concentration of Ni ions increases. Magnetic measurements show paramagnetic to ferrimagnetic transition at room temperature on Ni doping in ZnFe2O4 nanoparticles. The magnetic measurements also show spin canting in samples possibly due to their nanocrystalline nature. The spin canting angles have been calculated with the help of Yafet-Kittel (Y-K) model. Furthermore, the Law of approach (LA) fitting of M-H curves indicates that the samples are highly anisotropicin nature. The Arrot plots of as synthesized samples also indicate the paramagnetic to ferrimagnetic transition. The correlation between the structural and observed magnetic properties of NixZn1-xFe2O4(x=0.0, 0.5 and 1.0) nanocrystals will be described and discussed in this paper.

Full Text Available Introduction: Gout is crystal deposit arthritis and is an ancient disease. The biologic precursor to gout is hyperuricaemia. The prevalence of hyperuricaemia and gout has an increasing trend all over the world including the developing countries. The purpose of this study is to estimate serum uric acid level in hyperuricaemic and gout patients attending a medical college hospital. Methods: A consecutive 150 hyperuricaemics and 150 gout patients attending Tribhuwan University Teaching Hospital from June to September 2005 were included in this study. The serum uric acid level was measured by the enzymatic (PAP- Uricase method. The patients with acute gout were interviewed and relevant information was obtained. Results: Males comprised 84 % of gout cases. Hyperuricaemia was common in both sexes. The mean age for gout was 47.49 and 56.65 years in males and females respectively. The mean age for the first gout attack was 42.1 ± 14.0 years. Family history was positive in 22 % of cases. The overall mean serum uric acid level in hyperuricaemics was 7.2 ± 0.7 mg/dL and 8.4 ± 1.1 mg/dL in acute gout (p 0.0001. The mean serum uric acid level was signifi cantly (p 0.0001 high among males both at the asymptomatic phase and at acute gout. Gout was more common in non-vegetarians (95 % and alcoholics (65.3 %. Serum uric acid level was inversely related with the amount of daily water intake (p 0.0001. Conclusions: Serum uric acid level is signifi cantly high among the male gouty arthritic patients. However, it is also high among asymptomatic hyperuricaemic cases of both sexes. Keywords: asymptomatic hyperuricaemia, gout, serum uric acid level.

Science.gov (United States)

Tsunoo, Yukiyasu; Saito, Teruo; Shigeri, Maki; Kawabata, Takeshi

MISTY1 is a 64-bit block cipher that has provable security against differential and linear cryptanalysis. MISTY1 is one of the algorithms selected in the European NESSIE project, and it has been recommended for Japanese e-Government ciphers by the CRYPTREC project. This paper shows that higher order differential attacks can be successful against 7-round versions of MISTY1 with FL functions. The attack on 7-round MISTY1 can recover a partial subkey with a data complexity of 254.1 and a computational complexity of 2120.8, which signifies the first successful attack on 7-round MISTY1 with no limitation such as a weak key. This paper also evaluates the complexity of this higher order differential attack on MISTY1 in which the key schedule is replaced by a pseudorandom function. It is shown that resistance to the higher order differential attack is not substantially improved even in 7-round MISTY1 in which the key schedule is replaced by a pseudorandom function.

Time to Redefine Organic Agriculture: Can't GM Crops Be Certified as Organics?

Science.gov (United States)

Husaini, Amjad M; Sohail, Muhammad

2018-01-01

The challenges of sustainable food production without damaging the environment for a growing human population have increased considerably. The current agricultural practices involving chemical fertilizers and even organic farming are not sustainable in the long run and can have deleterious effects on the environment. Thus, new, innovative solutions need to be identified and propagated for tackling this. Among such innovations, that can complement conventional as well as organic farming methods, are genetic modification (GM) and aquaculture. Yet, GM technologies often face resistance from civil groups owing to an 'unknown' fear, akin to Frankenstein's monster. How real is this fear? Our discussion rests on basic questions like, why can't 'organics' include GM crops that do not require chemical inputs for cultivation, and can GM crops like Golden rice qualify to be 'organic' if cultivated through organic practices? Do we need to rethink organic agriculture in the context of the present and future challenges of 21st century?

Comparison of beverage consumption in adult populations from three different countries: do the international reference values allow establishing the adequacy of water and beverage intakes?

Science.gov (United States)

Nissensohn, Mariela; Fuentes Lugo, Daniel; Serra-Majem, Lluis

2016-07-13

Recommendations of adequate total water intake (aTWI) have been proposed by the European Food Safety Agency (EFSA) and the Institute of Medicine (IOM)of the United States of America. However, there are differences in the approach used to support them: IOM recommendation is based on average intakes observed in NHANES III (Third National Health and Nutrition Examination Survey) and EFSA recommendation on a combination of observed intakes from 13 different European countries. Despite these recommendations of aTWI, the currently available scientifi c evidence is not sufficient to establish a cut-off value that would prevent disease, reduce the risk for chronic diseases or improve health status. To compare the average daily consumption of fluids (water and other beverages) in selective samples of population from Mexico, US and Spain, evaluating the quantity of fluid intake and understanding the contribution of each fluid type to the total fl uid intake. We also aim to determine if they reached adequate intake (AI) values, as defi ned by three different criteria: IOM, EFSA and water density. Three studies were compared: from Mexico, the National Health and Nutrition Survey conducted in 2012 (NHNS 2012); from US, the NHANES III 2005-2010 and from Spain the ANIBES study leaded in 2013. Different categories of beverages were used to establish the pattern of energy intake for each country. Only adult population was selected. TWI of each study was compared with EFSA and IOM AI recommendations, as well as applying the criterion of water density (mL/kcal). The American study obtained the higher value of total kcal/day from food and beverages (2,437 ± 13). Furthermore, the percentage of daily energy intake coming from beverages was, for American adults, 21%. Mexico was slightly behind with 19% and Spain ANIBES study registered only 12%. ANIBES showed signifi cantly low AI values for the overall population, but even more alarming in the case of males. Only 12% of men, in

Full Text Available Starting from the assumption that texts produced in the tourist sector are a form of discourse, the paper focuses on narrative texts and singles out two sub-genres, namely travel literature proper and reports published on tourism websites. The corpus, comprising texts referring to India, is analysed with mainly qualitative methodology. Four aspects are considered in detail: enunciation and the author / reader relationship; the presence of subjective vs objective points of view; the time-space dimension; the exploitation of shared knowledge and stereotypes. The analysis reveals that the two sub-genres share some textual features and, despite their different literary value, both contribute to the construction of an image of the destination which can play a signifi cant role in tourism promotion.

2017-09-01

Eating disorders are severe mental illnesses that are challenging to treat and often follow a chronic course. They are associated with immense impairment on the psychological, physical, interpersonal, and social level as well as signifi cant direct and indirect cost. Therefore, prevention and early intervention are of utmost importance. Based on a qualitative literature review, we summarized the empirical evidence for the effi cacy of universal and selective prevention of eating disorders. Programs available in German and/or English were included in the review.

2008-04-01

Full Text Available The body of the adolescent dancer is the result of morphological, physiological and behavioral adaptations due to specific physical training. For the ballet master, body weight is irrelevant to evaluating the technical and artistic performance and beauty of a figure. All ballet dancers must have bodies that conform to the canon of international ballet in order to be able to perform in public. The purpose of this study is to describe the changes in the body composition of dancers at the Cuban National School of Ballet between two points in their training process. This was a longitudinal study of 54 girls and 40 boys, aged between 15 and 20 years old. An anthropometric protocol of 6 measurements was employed in order to determine body composition using the Durnin and Rahaman method for females and the Parizková and Buzková method for males. The main results demonstrate signifi cant increases in both weight and height for age in both sexes, and it was observed that height growth velocity decreased with age. The female dancers exhibited stable body fat percentages for all ages while male dancers signifi cantly reduced this percentage from one year to the next. The female students exhibited higher mean percentage body fat values than the normal range established in Cuba for elite athletes from competitive artistic sports and professional dancers, while the male students exhibited body fat percentages that were similar to these specialized groups. Resumo El cuerpo humano del bailarín adolescente es resultado de las adaptaciones orfológicas-fi siológicas y conductuales de un entrenamiento físico particular. Para los maestros de ballet el peso corporal no es relevante en la evaluación técnica-artística y de belleza de la fi gura del danzante. Cada bailarín tiene que cumplir con los cánones internacionales de fi gura del ballet para presentarse en el escenario artístico. El objetivo de esta investigación es describir las variaciones de la

Global flood risk models are now a reality. Initially, their development was driven by a demand from users for first-order global assessments to identify risk hotspots. Relentless upward trends in flood damage over the last decade have enhanced interest in such assessments. The adoption of the Sendai Framework for Disaster Risk Reduction and the Warsaw International Mechanism for Loss and Damage Associated with Climate Change Impacts have made these efforts even more essential. As a result, global flood risk models are being used more and more in practice, by an increasingly large number of practitioners and decision-makers. However, they clearly have their limits compared to local models. To address these issues, a team of scientists and practitioners recently came together at the Global Flood Partnership meeting to critically assess the question 'What can('t) we do with global flood risk models?'. The results of this dialogue (Ward et al., 2013) will be presented, opening a discussion on similar broader initiatives at the science-policy interface in other natural hazards. In this contribution, examples are provided of successful applications of global flood risk models in practice (for example together with the World Bank, Red Cross, and UNISDR), and limitations and gaps between user 'wish-lists' and model capabilities are discussed. Finally, a research agenda is presented for addressing these limitations and reducing the gaps. Ward, P.J. et al., 2015. Nature Climate Change, doi:10.1038/nclimate2742.

To introduce a technique of second order wave-shaped arch wire to orthodontically treat dental occlusal plane canting (DOPC) with left-right interactive anchorage, and to test its clinical efficacy. Among the permanent dentition malocclusion patients who showed no obvious facial asymmetry, we screened for patients who showed anterior occlusal plane canting (AOPC) after routine orthodontic examination, treatment planning, MBT fixed appliance installation and serial arch wires alignment. Each patient had been clinically appraised in frontal view by 2 orthodontists and the patient him/herself; if all 3 agreed that the AOPC was obvious, the patient was included. By this means, we included 37 patients, including 10 males and 27 females; the average age was (21.9±5.2) years. To correct AOPC, opposite direction equal curvature second order rocking-chair curve was bent on each side of 0.46 mm×0.56 mm stainless steel edgewise wire. With reference to normal occlusal plane, a curve toward the occlusal surface was made to extrude under-erupted teeth on one side while a curve toward the gingiva was made to intrude over-erupted teeth on the other side, so that the arch wire was made into a wave shape in vertical dimension. Before and after application of wave-shaped arch wire, frontal facial photographs were taken when the patient's mouth was open slightly with lips retracted to show anterior occlusal plane (AOP) clearly. An AOP was constructed by connecting the center of the slot in the medial edge of canine bracket on each side in the photograph. The angles between the bipupillary plane(BPP) and the constructed AOP were measured in ImageJ1-48v software and the angle differences before and after treatment were compared with paired Wilcoxon test in SPSS 10.0 software. The wave-shaped arch could correct AOPC effectively in 3 to 10 months time with an average of 5.5±1.7 months; the angles between AOP and BBP before treatment ranged from 2.90° to 6.12° with a median of 4.01�

Full Text Available Islamic banking has grown rapidly and has become fi nancial-nerve centre in today’s world economy, particularly in the last three decades. It has attracted various entrepreneurs and enterprises to get its fi nancing. However, Islamic banks tend to have a higher rate of fi nancing compared to the conventional ones. This less competitiveness encourage the demand for Islamic products may fall leaving the Islamic banks. Good debtors opted for conventional loans since the interest rates paid were relatively lower and the rest (the bad debtors successfully made their way to Islamic banks. Therefore, the nonperforming financing of Islamic banks is high. This paper attempts to analyze factors that determine high rate of fi nancing in Islamic banks, by taking the case of Malaysian Islamic banks. In this paper, the top three of Islamic banks and conventional banks are selected for comparison. It finds that high default premium and overheads per capital contribute signifi cantly to the high fi nancing rate. Hence, the Islamic banks should diversify their assets and implement universal banking concept.Keywords: Islamic bank, rate of fi nancing, NPF (Non-Performing Financing, universal banking system

Inferring disease transmission networks is important in epidemiology in order to understand and prevent the spread of infectious diseases. Reconstruction of the infection transmission networks requires insight into viral genome data as well as social interactions. For the HIV-1 epidemic, current research either uses genetic information of patients' virus to infer the past infection events or uses statistics of sexual interactions to model the network structure of viral spreading. Methods for a reliable reconstruction of HIV-1 transmission dynamics, taking into account both molecular and societal data are still lacking. The aim of this study is to combine information from both genetic and epidemiological scales to characterize and analyse a transmission network of the HIV-1 epidemic in central Italy.We introduce a novel filter-reduction method to build a network of HIV infected patients based on their social and treatment information. The network is then combined with a genetic network, to infer a hypothetical infection transmission network. We apply this method to a cohort study of HIV-1 infected patients in central Italy and find that patients who are highly connected in the network have longer untreated infection periods. We also find that the network structures for homosexual males and heterosexual populations are heterogeneous, consisting of a majority of 'peripheral nodes' that have only a few sexual interactions and a minority of 'hub nodes' that have many sexual interactions. Inferring HIV-1 transmission networks using this novel combined approach reveals remarkable correlations between high out-degree individuals and longer untreated infection periods. These findings signify the importance of early treatment and support the potential benefit of wide population screening, management of early diagnoses and anticipated antiretroviral treatment to prevent viral transmission and spread. The approach presented here for reconstructing HIV-1 transmission networks

Recognizing suicidal communication from the distressful catharsis in a high-risk group with suicidal tendencies is essential for suicide prevention. This study analyzes whether suicidal communication can indicate the severity of suicidal intent. Various types of suicidal communication are defined, and their clinical significance is further explored. A comprehensive analysis of the psychological autopsy data of 200 victims of completed suicide, including their general socio-demographic status, suicidal communication methods, previous suicide attempts, mental disorders, and psychosocial situation. Our results showed that 39.5% of all the subjects were suicidal communicators, 23.0% had previously attempted suicide, and 14.0% left suicide notes; 32.4% of 142 subjects free of physical disease suffered from mental disorders. Suicidal communication included verbal communication, behavioral communication, and suicidal notes. Younger people with a higher level of education were more inclined to communicate their suicidal intent by leaving a suicide note. Suicide notes, but not previous suicide attempts or psychosocial situation, were significantly correlated with suicidal intent. Suicidal communicators showed higher depression scores than non-communicators. Those who suffered from mood disorders with higher levels of both depression and suicidal intent were more likely to expose their intent through behavioral communication. The present study provides strong evidence that suicidal communication can indicate the severity of suicidal intent. Current findings help interpret high-risk, self-destructive behavior and consequently provide the theoretical basis for a feasible suicide prevention program.

2012-01-01

Full Text Available Nonresponse bias (and, to a lesser extent, measurement error has become the main source of error for electoral forecasts in Spain. Although the post-stratifi cation techniques and ratio estimators currently used in the polling industry reduce deviations, they do not show enough capacity to mend the biases introduced when collecting data. This research reveals how a more effi cient use of the electoral information available outside the sample could help to signifi cantly improve the accuracy of predictions, and uses simulation techniques to show that this may be accompanied by less expensive sampling designs. The analysis, nevertheless, also concludes that the proposed specifi cation is not a panacea and affi rms that there is still scope for reducing nonresponse bias, pointing to several issues for future research.

In this paper, we conduct research on the effectively building patterns of talent incentive and cultural atmosphere for modern enterprise management. Targeted incentive direction refers to the motivation, namely, to what kind of content to implement incentive. It has signifi cant effect on incentive effect. According to American psychologist Maslow’s hierarchy of needs theory, people’s behavior motives originated in fi ve kinds of need, namely: the physiological needs, security needs, belonging needs, respect for the needs and the self-actualization needs. People need not set in stone, which is a developing process from low to high, but the process is not a cascade of discontinuous jumping, but a continuous, the evolution of wave. Under this general basis, we propose the cultural atmosphere for modern enterprise management that is novel and innovative.

This report presents the results of systematic experiments conducted in a laboratory scale fluidized bed combustor in order to study agglomeration phenomena during firing straw and co-firing straw with coal. The influence of operating conditions on ag-glomeration was investigated. The effect of co......-firing straw with coal on agglomeration was also examined. The results show that temperature has the most pronounced effect on the agglomeration tendency. As bed temperature increases, the defluidiza-tion time decreases sharply, which indicates an increasing tendency of agglomera-tion. When co-firing straw...... with coal, the defluidization time can be extended signifi-cantly. Examination of the agglomerates sampled during combustion by various analytical techniques indicates that the high potassium content in straw is the main cause for the formation of agglomerates.

Inequality, Collective Action and Redistribution: a New Indicator for Assessing a Complex Relationship

Directory of Open Access Journals (Sweden)

Federico Traversa

2015-01-01

Full Text Available The predominant theoretical viewpoint about the problem of income redistribution in capitalist democracies continues to postulate that the pressure towards redistribution is greatest in democracies with more inequality. However, this assumption does not seem to be corroborated empirically; perhaps this is because sometimes inequality only increases between the lower reaches of the distribution of income. In these cases, inequality increases the dispersion of earnings among the stakeholders of redistribution, and this increases their collective action problems. This paper proposes a new theoretical principle for the analysis of the relationship between inequality and redistribution, and develops an indicator consistent to this principle. A preliminary empirical exploration is carried out to illustrate how the proposed indicator is signifi cantly associated with the levels of income redistribution in 19 OECD countries between 1974 and 2005.

Full Text Available Aim of the study was to evaluate patient and graft survival after liver transplantation (LT and to determine if primary disease diagnosis, early graft dysfunction or other factors affect it. Furthermore, we analyzed the reasonsof short-term and long-term deaths or retransplantations.Materials and methods. 192 LTs from donors with brain death were performed from December 2004 until June 2014. Recipient age varied from 5 to 71 years. Most frequent diagnosis was liver cirrhosis (mainly due to hepatitis C, then hepatocellular carcinoma (HCC, liver graft dysfunction, etc.Results and discussion. 1-year patient survival is 89.5%, graft survival is 87.7%, 3-year –87% and 84.6%, respectively, and 5-year – 83.5% and 83.0%, respectively. Early mortality (in fi rst 30 days after transplantation was 8%, long-term mortality – 5.9%. Primary non-function graft (PNF was the reason of 66.7% early deaths. In the long term, infections and oncology were the reasons of death with the same frequency – 36.4%. Early graft dysfunction including primary non-function signifi cantly decreases short term survival (p = 0.0002. Nevertheless, in the majority of cases graft function improves and doesn’t affect survival. Donor factors play role in outcomes: early dysfunction is higher (40.6% in extended criteria donor group than in standard donor group (р = 0.0431. PNF has the same trend – 8.5% and 0.0%, respectively, but without signifi cance (р =0.0835. 5-year survival is remarkably lower in HCC group 40.8% (p = 0.003 than in other groups.Conclusion: survival after liver transplantation in our Center is comparable with the results of the world’s centers.

Aerosol-Cloud-Precipitation Interactions in WRF Model:Sensitivity to Autoconversion Parameterization

Institute of Scientific and Technical Information of China (English)

解小宁; 刘晓东

2015-01-01

Cloud-to-rain autoconversion process is an important player in aerosol loading, cloud morphology, and precipitation variations because it can modulate cloud microphysical characteristics depending on the par-ticipation of aerosols, and aff ects the spatio-temporal distribution and total amount of precipitation. By applying the Kessler, the Khairoutdinov-Kogan (KK), and the Dispersion autoconversion parameterization schemes in a set of sensitivity experiments, the indirect eff ects of aerosols on clouds and precipitation are investigated for a deep convective cloud system in Beijing under various aerosol concentration backgrounds from 50 to 10000 cm−3. Numerical experiments show that aerosol-induced precipitation change is strongly dependent on autoconversion parameterization schemes. For the Kessler scheme, the average cumulative precipitation is enhanced slightly with increasing aerosols, whereas surface precipitation is reduced signifi-cantly with increasing aerosols for the KK scheme. Moreover, precipitation varies non-monotonically for the Dispersion scheme, increasing with aerosols at lower concentrations and decreasing at higher concentrations. These diff erent trends of aerosol-induced precipitation change are mainly ascribed to diff erences in rain wa-ter content under these three autoconversion parameterization schemes. Therefore, this study suggests that accurate parameterization of cloud microphysical processes, particularly the cloud-to-rain autoconversion process, is needed for improving the scientifi c understanding of aerosol-cloud-precipitation interactions.

2015-09-01

Full Text Available The neologism noosphere signifies global human consciousness. According to T. de Chardin, it is the third stage in the development of the earth, after the geosphere and the biosphere. As well as the emergence of life has fundamentally changed the geosphere, the emergence of human consciousness has fundamentally changed the biosphere. De Chardin envisioned the “planetarization” of mankind, which is equivalent to the current globalization by information technology. From an anthropological point of view, internet is not a technology or media as others: it has the potential to revolutionize the current civilizational paradigm. With the advent of the internet the idea of the noosphere has been reactualized and related to the concept of collective intelligence. The article questions the hypothesis of an evolutionary leap in a greater collective intelligence or higher level of collective consciousness presenting pros and cons.

Full Text Available Aims and Objectives: The purpose of the study was to assess the skeletal and dental effects of fan-type rapid maxillary expansion (RME appliance and Hyrax RME appliance on the craniofacial structures. Materials and Methods: The sample of the study included 12 patients with constricted maxillary arches. Acrylic bonded type of attachment was used for both groups. Changes in sagittal, vertical, and transverse relationship were assessed with lateral and frontal cephalograms, respectively. Intercanine and intermolar widths were measured with stone models. Pre- and immediate post-treatment records were statistically analyzed with Wilcoxon signed-rank test. The differences between the groups were evaluated using Mann–Whitney U-test. Since the data pertaining to intercanine width and intermolar width were normally distributed, parametric test of signifi cance (unpaired t-test was used to compare them. Results: Results showed that Hyrax presented with signifi cantly greater increments for both nasal cavity width and maxillary width when compared to fan-type RME. Both groups had retroclination of incisors. The increase in the intercanine width was almost similar in both groups. Conclusion: Fan-type RME caused only minimal expansion of the intermolar width when compared to the Hyrax. The ratio between the intercanine and intermolar width expansion was nearly 4:1 in the fan-type RME and 0.75:1 in Hyrax.

Anthropogenic carbon (Cant) concentration is determined according to the TrOCA method, from carbonate system data and hydrographic parameters collected during two consecutive spring cruises (2007 and 2008) in the Argentinean Patagonian shelf-break zone between 36°S and 50°S. Cant has intruded the water column until intermediate depths, with no Cant below 1000 m, in the deeper waters (i.e., North Atlantic Deep Water and Antarctic Bottom Water) of the Northern sector of the study area (i.e., North of 38°S). The higher Cant concentration is observed in Subantarctic Shelf Water in the Southern region, whereas in the Northern sector both Tropical Water and South Atlantic Central Water are equally affected by Cant intrusion. The Antarctic Intermediate Water represents the depth-limit achieved by Cant penetration, reinforcing the role that this water mass plays as an important vehicle to transport Cant to the oceans interior. The estimated Cant average (± method precision) is 46.6 ± 5.3 μmol kg- 1, considering the full depth of the water column. The ocean acidification state (ΔpH) shows an average (± standard deviation) of - 0.11 ± 0.05, thus, indicating an annual pH reduction of - 0.0010 yr- 1 since the Industrial Revolution (c.a. 1750). The degree of aragonite saturation is lowered towards undersaturation levels of calcite. The Patagonian shelf and shelf-break zones-a strong CO2 sink region in the global ocean-are likely a key area for Cant intrusion in the southwestern South Atlantic Ocean.

Full Text Available The aim of the study was to analyse the diversity of return on equity in the cooperative banks in Poland in 2010– 2014. The analysis was conducted using data of the Polish Financial Supervision Authority, on the basis of a modifi ed decomposition rate of return on equity. Assessment of the rate of return on equity was made in a size of banks, as determined by the value of assets. In addition, in order to determine the strength and direction of impact the individual components of the model on the formation of return on equity method was applied functional. The study suggests that cooperative banks eff ectively use the equity, because the rate of return on equity was signifi cantly higher than the rate of return on assets. The average return on assets in 2010–2014 was relatively lower in the largest banks and ranged from 0.7–0.9%, and the smallest banks return on assets was approximately 1%. In turn, the return on equity was higher at banks with major assets (over 200 million PLN. In 2013–2014 the rate of return both on assets and equity expressly declined. The main determinants of changes in return on equity were changing the multiplier reduction of profi t from banking activities by operating costs and costs of banking risk and return on assets, as well as measured result on banking activities.

Full Text Available Our study analyses the current status of the Biosphere Reserves on the Cantabrian Mountains, especially the relationships that they have with other Protected Natural Areas with which very often coincide. These relationships concerns management bodies and one of their main problems that has to do with their negative demographic dynamic that has led to an intense depopulation and aging of their local population. Although twelve reserves have been declared, there are still many areas which have not been named reserves but they potentially could. This tells us that we are still far from a Biosphere Reserve of the Great Cantabrian Mountain Range. The management is different depending on the regions: in Asturias, it is the regional administrative department which performs its management; in Galicia, the provincial administrative department and in Castilla and León, it’s the local government who is in charge of its management. Depopulation is one of the most serious problems suffered almost by every Cantabrian reserves and as a process has not stopped yet. The status of the Biosphere Reserve has yet to find its place in the context of other figures that are clearly under protection. In general, the aim of our study is to underline the importance of separating this figure from other more consolidated concerning Protected Natural Areas, and also, to raise awareness about the serious process of aging and depopulation expressed in their territories.Se analiza la situación actual de las Reservas de la Biosfera de la Cordillera Cantábrica, en especial las relaciones que tienen con los Espacios Naturales Protegidos, con los que a menudo coinciden, las relativas a sus órganos de gestión y a uno de sus principales problemas actuales: su dinámica demográfica negativa que ha desembocado en una intensa despoblación y envejecimiento.

Normal pregnancy is characterized by progressive insulin resistance, which is physiologically compensated by an increase in insulin secretion. The higher secretion of the insulin precursor pro-insulin has been associated with β-cell dysfunction. A total of 102 pregnant women between 24-28 gestational weeks (53 GDM pregnant, 49 with NGT and 22 postpartum with GDM history, as assessed by a 2h oral glucose tolerance test, were included in the study.

Full Text Available The subject of the article is export processing zones of Bangladesh, which may become a sample for development of mechanic engineering in Russia. Export processing zone, as a kind of special economic zones, is a quite useful tool for the country's economy. They allow reaching a number of government objectives: increase employment, attract investment and enhance volume of collected taxes. In addition to the direct eff ect, the emergence of export processing zones has indirect impact on the economy by increasing purchases from suppliers by SEZ residents. Providing tax and customs benefi ts to residents, the state puts companies outside the zones at a disadvantage. However, to counter this, state imposes restrictions on admission of products of resident companies on domestic market. These restrictions may relate to establishment either of a certain percentage of products that can be delivered freely on the internal market or share that can be delivered after payment of customs duties and taxes. The purpose of this work is to show the results of Bangladesh EPZs and to present basic directions of development for such zone specialized in mechanic engineering in Russia. The methodological base of the research is comparative analysis, cause-eff ect relationships, as well as historical method. In this article the author analyzes the experience of creation of export processing zones in Bangladesh, where they are suffi ciently proven: new jobs and enterprises have been created - investments to these zones account for a signifi cant share of total investments to the country. Moreover export of Bangladesh has increased signifi cantly. At the same time the goal for diversifying the country industry has not been met: textile is the main branch is in these zones.

Full Text Available The aim of this paper is to discuss the legal and economic aspects of granting state aid for environmental protection in the Member States in respect of the competition policy of the European Union in the years 2004–2012. For the purpose of this study, deductive, descriptive and criticalcognitive methods were applied in order to analyze the theoretical knowledge contained in the literature of the subject as well as in legal and normative acts. Empirical data were derived from studies, documents and reports of the DirectorateGeneral for Competition of the European Commission and the Offi ce of Competition and Consumer Protection. Based on the study, in the years 2004–2012 in the EU horizontal objectives mostly involved aid granted for the purposes of environmental protection (123 bln EUR, 24.3%. The total expenditure for environmental protection in the EU was strongly determined by decisions taken by Germany and Sweden. The most signifi - cant benefi ciaries who were granted such aid were entrepreneurs from Great Britain, the Netherlands, Austria and Spain. More than half of the decisions (54% issued by the European Commission were taken by fi ve countries: Italy, Great Britain, the Netherlands, Germany and Spain. Investments in renewable sources of energy were most often subsidized. Moreover, companies were granted aid in order to adjust to requirements stricter than the EU standards in the fi eld of environment. A smaller percentage of aid was allocated to fi nance environmental research and to improve energy effi ciency (cogeneration, including heating and cooling systems.

Higher-order turbulence characteristics such as turbulence production, turbulence kinetic energy flux, third order moments and velocity spectra associated with turbulent bursting events due to the influence of a submerged hemisphere under wave–current interactions are presented. The velocity components were measured using three dimensional (3D) 16 MHz micro-acoustic Doppler velocimetry (Micro-ADV). In the wave–current interactions, the contributions of turbulent bursting events such as ejections and sweeps significantly reduce in comparison to the current-only case. The distributions of the mean time intervals of ejection and sweeping events are found to alter due to the superposition of surface waves. Results also depict that the turbulence production in the wake region of the hemisphere reduces remarkably, due to the superposition of surface waves on the current. Further, spectral and co-spectral analysis demonstrates that there is a significant reduction of power spectral peak for both longitudinal and bottom-normal velocities upon superposition of surface waves, which signifies a remarkable change in energy distribution between different frequencies of waves.

What can('t) we do with global flood risk models?

Science.gov (United States)

Ward, Philip; Jongman, Brenden; Salamon, Peter; Simpson, Alanna; Winsemius, Hessel

2015-04-01

In recent years, several global scale flood risk models have become available. Within the scientific community these have been, and are being, used to assess and map the current levels of risk faced by countries and societies. Increasingly, they are also being used to assess how that level of risk may change in the future, under scenarios of climate change and/or socioeconomic development. More and more, these 'quick and not so dirty' methods are also being used in practice, for a large range of uses and applications, and by an increasing range of practitioners and decision makers. For example, assessments can be used by: International Financing Institutes for prioritising investments in the most promising natural disaster risk reduction measures and strategies; intra-national institutes in the monitoring of progress on risk reduction activities; the (re-)insurance industry in assessing their risk portfolios and potential changes in those portfolios under climate change; by multinational companies in assessing risks to their regional investments and supply chains; and by international aid organisations for improved resource planning. However, global scale flood risk models clearly have their limits, and therefore both modellers and users need to critically address the question 'What can('t) we do with global flood risk models?'. This contribution is intended to start a dialogue between model developers, users, and decision makers to better answer this question. We will provide a number of examples of how the GLOFRIS global flood risk model has recently been used in several practical applications, and share both the positive and negative insights gained through these experiences. We wish to discuss similar experiences with other groups of modelers, users, and decision-makers, in order to better understand and harness the potential of this new generation of models, understand the differences in model approaches followed and their impacts on applicability, and develop

Full Text Available Allergies and/or food intolerances are a growing problem of the modern world. Diffi culties associated with the correct diagnosis of food allergies result in the need to classify the factors causing allergies and allergens themselves. Therefore, internet databases and other bioinformatic tools play a special role in deepening knowledge of biologically-important compounds. Internet repositories, as a source of information on different chemical compounds, including those related to allergy and intolerance, are increasingly being used by scientists. Bioinformatic methods play a signifi cant role in biological and medical sciences, and their importance in food science is increasing. This study aimed at presenting selected databases and tools of bioinformatic analysis useful in research on food allergies, allergens (11 databases, epitopes (7 databases, and haptens (2 databases. It also presents examples of the application of computer methods in studies related to allergies.

Full Text Available Accumulations of large quantities of wastes (manure, used litter, dead birds which are excellent medium for fly-larvae over poultry houses provide breeding places for different groups of fly pests, with house-flies being the dominant species. This project is a comparative lab study. In this research project the larvicidal effects of cyromazine and triflumuron were studied as two Insect Growth Regulators (IGRs to reduce the fly population using oral application. Both IGRs had a signifi-cant effect on larval mortality compared with their controls among the concentrations (P< 0.01, Fisher's LSD with Bonf-feroni correction including a dose-dependent relationship. Comparisons among LC50 and LC90 values, using fiducial limits, showed that cyromazine was significantly more toxic to the larvae of the two strains than triflumuron. It is concluded that cyromazine should be used in a larvicidal programme to control house-fly rather than triflumuron.

Full Text Available Background: The high prevalence of anemia pregnant women anemia in Indonesia reaches 50%–70%, and it is caused by many factors. First, it may be caused by low compliance of iron supplementation and second, it may be caused by bad distribution of iron supplementation. This prevalence results some effect: high maternal mortality rate, neonatal mortality rate, anemia in infancy, and low productivity. One solution to overcome this prevalence is by giving iron supplementation to pregnant women with husband’s supervision. Objective: This study aims to examine the relationship between iron supplementation with compliance, Hb value, and average of age gestation under husband’s supervision. Methods: This was quasi experimental non-equivalent control group design. Subjects were pregnant women aged 20–28 weeks whose hemoglobin level 8 gr/dl to 15 gr/dl. Subject were taken from three sub-districts of Bantul District, Special Teritory of Yogyakarta. Subject were divided into two groups, the first group (n=55 received 60 mg iron supplementation with husband’s supervision and the second group (n=65 received 60 mg iron supplementation without husband’s supervision. Results: The compliance of first the group was higher than the second group (x2=19,48 p0,05. In the second group, iron supplementation was also effective to increase Hb level and it is statistically significant (p<0,05. The difference of Hb level between two groups was insignifi cant. After the predictor variable was controlled using multivariate regression test, it showed that iron supplementation with husband’s supervision was effective to increased Hb level 0,8 gr/dl and statistically signifi cant (p<0,05. The gestation average of two groups was similar, but after predictor variable was controlled using multivariate test, it showed that iron supplementation with husband’s supervision had one week gestation longer than those group without husband’s supervision.

Full Text Available Shelled peanuts of Gajah var. with initial moisture content of 7% were stored at 11 kg/bag in four bag types namely: jute bag, polypropylene bag, jute bag doubled with thin polyethylene (PE, and jute bag doubled with thick PE. Storage was done for six months under warehouse conditions with monitoring of relative humidity and temperature. Samples taken at the be ginning of storage and every month thereafter were analyzed for moisture content, fungal population, aflatoxin and free fatty acid contents. Statistical analyses showed that moisture content, fungal population, and free fatty acid contents were signifi cantly higher in jute and polypropylene bags than in PE-dou,bled jute bags. No significant differences were obtained in aflatoxin contents among bag types but at the end of six months storage, toxin level in jute bag exceeded the 30 ppb limit. Polypropylene had second highest toxin level at 23 ppb. The PE-doubled bags ha d 17 and 19 ppb total aflatoxins for thin and thick films, respectively. The results indicated that the immediate packag ing of dried shelled peanuts at safe moisture level in plastic films with water vapor transmission rated of 1 g/m2/24 hr or lower is recommended. This p ackaging will delay critical increases in moisture content, fungal population, aflatoxin and free fatty acid contents of peanut kernels at ambient storage conditions.

Can migration mitigate the effects of ecosystem change? Patterns of dispersal, energy acquisition and allocation in Great Lakes lake whitefish (Coregonus clupeaformis)

Rennie, Michael D.; Ebener, Mark P.; Wagner, Tyler

2012-01-01

Migration can be a behavioural response to poor or declining home range habitat quality and can occur when the costs of migration are overcome by the benefi ts of encountering higher-quality resources elsewhere. Despite dramatic ecosystem-level changes in the benthic food web of the Laurentian Great Lakes since the colonization of dreissenid mussels, coincident changes in condition and growth rates among benthivorous lake whitefi sh populations have been variable. We hypothesized that this variation could be in part mitigated by differences in migratory habits among populations, where increased migration distance can result in an increased probability of encountering high-quality habitat (relative to the home range). Results from four Great Lakes populations support this hypothesis; relative growth rates increased regularly with migration distance. The population with the largest average migration distance also had the least reduction in size-at-age during a period of signifi cant ecosystem change and among the highest estimated consumption and activity rates. In comparison, the population with the greatest declines in size-at-age was among the least mobile, demonstrating only moderate rates of consumption and activity. The least mobile population of lake whitefi sh was supported by a remnant Diporeia population and has experienced only moderate temporal growth declines. Our study provides evidence for the potential role of migration in mitigating the effects of ecosystem change on lake whitefi sh populations.

Full Text Available Background: Vegetables play an important role in human nutrition. Nitrate content is a signifi-cant quality criterion to determine characteristic of vegetables. About 80% of nitrate intake in human is from vegetables and fruits. High dietary intake of nitrate is seen as an undesirable be-cause of its association with gastric cancer and infantile methemoglobinemia. Varzeghan, North-western Iran is one of the cities with high Age-standardized incidence rates (ASR of gastric can-cer in Iran. Currently, in Varzeghan there is no available and accurate information describing ni-trate concentration as one of the important risk factors of vegetables for human consumption.Methods: In this cross sectional study totally 11 types of vegetables (cabbage, lettuce, spinach, parsley, coriander, dill, leek, fenugreek, tarragon, fumitory and mint from several different green-grocery of Varzeghan were collected in spring (April and autumn (November and December 2011 and their nitrate contents were analyzed.Results: Mean nitrate contents at the above noted fresh vegetables were 161, 781, 83, 707, 441,501, 1702, 684, 805, 772 and 191 mg NO3-kg-1 respectively.

Full Text Available Understanding the notion of learner’s experiences in the design of physical environment of an architecture design studio is a necessity as it contains certain values of influence. It is due to the unique learning experiences which are accrued particularly in design studio that is continued during professional practice as well. Most architectural campuses in Malaysian Private Higher Education Institutions (MPHEI are devoid of certain important elements and this issue needs to be looked into seriously. Apparently, most architectural design studios today have different physical settings, and have developed their own learning culture based on the typical space that they have. Reviewing the physical environment and how it contributes to the social environ-ment in MPHEI’s architectural context requires certain understanding on the learner’s psycho-logical needs, expectations and in the same time to meet the educational objective which is never an easy task. Hence, this paper reviewed the studies of the possible physical environment approaches in connecting the learner’s connections in architecture studio learning environ-ment. A questionnaire survey with Likert-scale components, and semi-structured interview on learners of five distinguished Private Architectural schools in Malaysia unveiled several signifi-cant findings that can lead entrepreneurs to upgrade the physical environment of these MPHEIs in order to cope with the demands of the stakeholders.

We have reported new magnetic and optical properties of Mn 2 O 3 nanostructures. The nanostructures have been synthesized by the hydrothermal method combined with the adjustment of pH values in the reaction system. The particular characteristics of the nanostructures have been analyzed by employing X-Ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray (EDX) analysis, transmission electron microscopy (TEM), high resolution transmission electron microscopy (HRTEM), Raman spectroscopy (RS), UV—visible spectroscopy, and the vibrating sample magnetometer (VSM). Structural investigation manifests that the synthesized Mn 2 O 3 nanostructures are orthorhombic crystal. Magnetic investigation indicates that the Mn 2 O 3 nanostructures are antiferromagnetic and the antiferromagnetic transition temperature is at T N = 83 K. Furthermore, the Mn 2 O 3 nanostructures possess canted antiferromagnetic order below the Neel temperature due to spin frustration, resulting in hysteresis with large coercivity (1580 Oe) and remnant magnetization (1.52 emu/g). The UV—visible spectrophotometry was used to determine the transmittance behaviour of Mn 2 O 3 nanostructures. A direct optical band gap of 1.2 eV was acquired by using the Davis—Mott model. The UV—visible spectrum indicates that the absorption is prominent in the visible region, and transparency is more than 80% in the UV region

Rheumatoid arthritis (RA) may have an onset at older age. The onset of the disease at the age of 60 and over is called late-onset rheumatoid arthritis (LORA). The aim of this study was to analyze the clinical, laboratory, radiological, and treatment characteristics of patients with LORA compared to those with early-onset RA (EaORA), provided that all the patients had an approximately equal duration of the disease. This is an observational single-center study, which involved 120 patients with an established diagnosis of RA, of which 60 patients had LORA, and 60 patients EaORA. The disease activity, measured by the Disease Activity Score 28 (DAS28-ESR), was significantly higher in the LORA group compared to the EaORA group (p0.05), while the number of patients positive for anti-citrullinated protein antibody (ACPA) was signifi cantly greater in the EaORA group (p<0.05). The values of C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) were significantly higher in the LORA than in the EaORA group. Hemoglobin levels were lower in the LORA group (11.96±1.64 g/dL) than in the EaORA group (12.18±1.56 g/dL). The most used disease-modifying antirheumatic drugs (DMARDs) were methotrexate and sulfasalazine, while biological drugs were not used. In conclusion, based on the results of our study, LORA has some features that distinguish it from EaORA, such as higher disease activity, more frequent involvement of large joints, and more pronounced structural damage. This should be taken in account in clinical practice, especially regarding treatment choices.

Full Text Available Practice of rooming-in meant that baby and mother stayed together in the same room day and night in the hospital, right from the time of delivery till the time of discharge. Adoption of rooming-in offers multiple benefits to the newborn, mother, and mother-child as a unit. It is a cost-effective approach wherefewer instruments are required and spares additional manpower. Rooming-in endeavors the opportunity to contribute signifi cantly in the child’s growth, development and survival by assisting in timely initiation of breastfeeding. To ensure universal application of rooming-in in hospitals, a comprehensive and technically sound strategy should be formulated and implemented with active participation of healthcare professionals. Measures such as advocating institutional delivery through outreach awareness activities; adoption of baby-friendly hospital initiative; inculcating a sense of ownership among health professionals, can be strategically enforced for better maternal and child health related outcomes.

Lithospermum Ruderale extract was administrated 3 d before, 3 d after or 3 d before plus 3 d after the admin istration of misoprostol respectively. The dose of Lithospermum Ruderale extract was 50 g, 75 g or 100g respectively. Thus 1 350 women of early pregnancy were grouped into 9 groups and observed. The results showed that the effects of Lithospermum Rud erale used 3 d before, and 3 d before plus 3 d after (6 days misoprostol were signifi cantly better than those only used 3 d after misoprostol both for complete abortion and bleeding (P＜0.05). The dosage between 50 g and l00 g made no significant differ ence in clinical effects. Therefore it is reasonable to use 50 g Lithospermum Ruderale before misoprostol to improve medicinal abortion.

PPI-IRO: A two-stage method for protein-protein interaction extraction based on interaction relation ontology

KAUST Repository

Li, Chuanxi

2014-01-01

Mining Protein-Protein Interactions (PPIs) from the fast-growing biomedical literature resources has been proven as an effective approach for the identifi cation of biological regulatory networks. This paper presents a novel method based on the idea of Interaction Relation Ontology (IRO), which specifi es and organises words of various proteins interaction relationships. Our method is a two-stage PPI extraction method. At fi rst, IRO is applied in a binary classifi er to determine whether sentences contain a relation or not. Then, IRO is taken to guide PPI extraction by building sentence dependency parse tree. Comprehensive and quantitative evaluations and detailed analyses are used to demonstrate the signifi cant performance of IRO on relation sentences classifi cation and PPI extraction. Our PPI extraction method yielded a recall of around 80% and 90% and an F1 of around 54% and 66% on corpora of AIMed and Bioinfer, respectively, which are superior to most existing extraction methods.

An urgent issue for power plants operating on solid fuels (coal) is the issue of utilization or use of accumulated production waste - ash and slag materials - in the related production. Ash-slag materials are classified as "waste", usually grade 5; tens of millions of tons of them being pro-duced annually in the Kemerovo region, which threatens the ecology of the region. At the same time, ash and slag is a very promising raw material. The use of this material as a base for the final product allows us to signifi-cantly expand the possibilities of using coal. The most widespread is the system of ash and slag involving in construction or as a replacement for sand in road construction, or as an additive to building mixtures. However, there are both industrially valuable and environmentally dangerous ele-ments in ash-slag materials. Ash-slag materials can be considered as inde-pendent ore deposits located on the surface and requiring the costs of their extraction.

Full Text Available The literature on the division of domestic work has revealed the influence of the life cycle on family organization. Concretely, the arrival of children seems to have a signifi cant impact on the division of domestic tasks. This article looks at the effect of parenthood in the Spanish case, examining whether couples with children have a more traditional division of work than couples without children, and if so, in what way, and whether there have been changes in this trend over time. For this purpose, we follow the the empirical strategy of Dribe and Stanfors (2009 for the Swedish case, analyzing the time devoted to different activities using data from time use surveys from 2002-2003 and 2009-2010. The results show that couples with children have a more traditional division of labor than couples without children, and that it is also affected by the age of the children. In addition, our fi ndings show this trend was less pronounced in 2009-10.

Full Text Available he preliminary results obtained from the analysis in the micropulsation frequency range of high time resolution magnetic field data recorded at the Antarctic Italian geomagnetic observatory at Terra Nova Bay for 11 consecutive days in February 1994 are reported. The spectral index over the whole Pcl-Pc5 frequency range is of the order of 3.5 and its value significantly increases beyond about 50 mHz. Spectral peaks in the Pc3 frequency range are common, especially during the daytime hours, and are probably due to the direct penetration of upstream waves in the cusp region. From the local time distribution of the micro pulsation power, a signifi - cant activity enhancement around the local magnetic noon emerges, in agreement with previous observations. The analysis of the signal polarisation characteristics in the horizontal plane shows a predominant CW polarisation in the Pcl-Pc3 frequency ranges with the major axis of the polarisation ellipse in the first quadrant.

Full Text Available Introduction: Tuberculosis is still a serious public health problem. Young age and HIV infection are important risk factors for severe or disseminated disease. Case report: We report the case of a three-year-old girl who presented a prolonged fever without a source on physical examination. Initial laboratory fi ndings were suggestive of urinary tract infection and empirical antibiotic therapy was started. Urine culture confi rmed that diagnosis, but fever had persisted. On complementary investigation, chest X-ray revealed an< infiltrate with a miliary pattern. Mycobacterium tuberculosis was isolated on gastric aspirate, cerebrospinal fluid and urine. Antituberculous therapy and corticoid were initiated with signifi cant clinical improvement. Conclusions: Even in this era of advanced medical technology, tuberculosis is still a diagnostic challenge, especially when the presentation is atypical and extra-pulmonary. A high index of suspicion by the physician is required because prompt institution of adequate treatment is decisive for fi nal outcome.

Postmaterialist Values and Adult Political Learning. Intracohort Value Change in Western Europe

Directory of Open Access Journals (Sweden)

Raül Tormos

2012-01-01

Full Text Available Research on value change and stability tends to underline the importance of generational effects, Inglehart's theory of post-materialism being an example of this. According to his theory, formative experiences shape the values of each age-cohort, and social change takes place progressively due to the force of generational replacement. This article analyzes survey data covering a wider period of observations than the one Inglehart used to draw his conclusions. By applying time series techniques, I find signifi cant changes within each generation over time. I show how an important adult learning process in the field of post-materialist values has taken place, which has been neglected by the empirical literature. Contrary to Inglehart's point of view, I conclude that period effects are not just minor short-term infl uences affecting the "normal" change due to generational replacement, but a systematic intracohort trend linked to the European economic prosperity of recent decades.

Full Text Available Storage of waste substances is not indifferent to ecological equilibrium in the environment therefore should not be the ultimate way to limit waste arduousness. Therefore, the conducted investigations aimed to determine the effect of tannery composts and vermicomposts loaded with chromium on this element bioaccumulation in earthworm bodies and biomass of selected plants. Chromium in composts and vermicomposts based on tannery sludges occurred in small quantities and easily soluble compounds. Chromium concentrations in redworm biomass points to this metal accumulation in Eisenia fetida body tissues. This element content in redworm biomass was signifi cantly positively correlated with its content in composts. Chromium content in plants was diversifi ed and on treatments was generally smaller than on mineral treatment or farmyard manure. Chromium absorbed by plants was stored mainly in the root systems, and over the norm content of this element found in vermicomposts did not cause its excessive accumulation in plant biomass.

Full Text Available This paper examines the effect of trade openness and per capita GDP on the size of government for Turkey and South Korea by means of ARDL approach to co-integration. We use different proxies to measure the size of government because not all measures of government size are appropriate to be employed in the estimates. Among the three (four different measures of government size of Korea (Turkey, only one for each country has a co-integrating relationship with openness and per capita GDP. Long run coeffi cients suggest that per capita GDP has a positive and signifi cant effect on the government sizes for Turkey and Korea, implying the validity of the Wagner’s law. However, while openness has a negative effect on government size for Turkey, it has a positive effect for Korea. Our results clearly highlight the importance of choosing an appropriate proxy for government size to reach robust and consistent results.

Highlights: • Rietveld refinement of CoIn{sub x}Fe{sub 2−x}O{sub 4} samples confirm single phase spinel structure. • The in-field Mössbauer study reveals canted spin structures in CoIn{sub x}Fe{sub 2−x}O{sub 4} ferrites. • In-field Mössbauer study is in line with magnetization measurements. • Cation distribution matches well with experimental integrated intensity ratios. • Shifting of resonance peaks to high frequencies is useful for industrial purposes. - Abstract: In the present work, In{sup 3+} substituted cobalt ferrites (CoFe{sub 2−x}In{sub x}O{sub 4}, x = 0.0, 0.2, 0.4, 0.6, 0.8, 1.0) have been synthesized via solid-state reaction technique. The Rietveld fitted X-ray diffraction patterns confirm the formation of single phase cubic spinel structure with space group Fd3{sup ¯}m for all the samples, with additional slight traces of secondary phase for x = 0.6, 0.8 and 1.0 samples. The low temperature (5 K)–high field Mössbauer (5T) spectra are analyzed in detail for probing the magnetic properties of Fe based In{sup 3+} substituted cobalt ferrites. The canted spin structures associated with Fe{sup 3+} ions both at A- and B-sites in the presence of external magnetic field of 5T have been noticed in all the samples. A fair agreement is obtained between the experimental integrated intensity ratios of {sup 57}Fe Mössbauer spectra at A- and B-sites and those calculated on the basis of cation distribution. The effect of In{sup 3+} substitution on various Mössbauer parameters viz hyperfine field distribution, isomer shift, quadrupole splitting and the line width has also been noticed. The magnetization measurements performed at low temperature also reveal the canted spin structures in all the samples. The variations in initial permeability over a wide range of frequency (125 kHz–30 MHz) at 300 K have also been recorded. The initial permeability study reveals the occurrence of resonance phenomenon at very high frequencies which widens the area

The study cohort encompasses a consecutive series of 175 patients surgically treated with pancreaticoduodenectomy for pancreatic and periampullary adenocarcinoma in Malmö and Lund University Hospitals, Sweden, between 2001-2011. Tissue microarrays were constructed from primary tumours (n = 175 and paired lymph node metastases (n = 105. A multiplied score was calculated from the fraction and intensity of pIgR staining. Classification and regression tree analysis was used to select the prognostic cut-off. Unadjusted and adjusted hazard ratios (HR for death and recurrence within 5 years were calculated. pIgR expression could be evaluated in 172/175 (98.3% primary tumours and in 96/105 (91.4% lymph node metastases. pIgR expression was significantly down-regulated in lymph node metastases as compared with primary tumours (p = 0.018. Low pIgR expression was significantly associated with poor differentiation grade (p < 0.001, perineural growth (p = 0.027, lymphatic invasion (p = 0.016, vascular invasion (p = 0.033 and infiltration of the peripancreatic fat (p = 0.039. In the entire cohort, low pIgR expression was significantly associated with an impaired 5-year survival (HR = 2.99, 95% confidence interval (CI 1.71-5.25 and early recurrence (HR = 2.89, 95% CI 1.67-4.98. This association remained significant for survival after adjustment for conventional clinicopathological factors, tumour origin and adjuvant treatment (HR = 1.98, 95% CI 1.10-3.57. These results demonstrate, for the first time, that high tumour-specific pIgR expression signifies

Our objective was to report the orthodontic and surgical retreatment of a patient who had undergone a prolonged orthodontic treatment with extractions, but who had unsatisfactory results and persistent side effects. The man, aged 25 years 3 months, sought treatment with major complaints of facial and smile asymmetries. The clinical examination showed a mandibular deviation to the right and a maxillary occlusal cant. A Class II Division 1 subdivision right was observed. Radiographic examination showed extensive root resorptions in the maxillary second premolars and absence of the 4 first premolars. The maxillary midline was deflected 2 mm to the left, and the mandibular midline was shifted 5 mm to the right. Aligning and leveling were performed with orthodontic fixed appliances, with a standard edgewise system (0.022 × 0.028 in), followed by LeFort I maxillary impaction and bilateral sagittal split osteotomy with asymmetrical advancement. Retreatment showed outstanding results that remained stable after 3 years of follow-up. Root resorption in the second premolars did not seem to increase. Orthodontic-surgical intervention is the main choice for correcting esthetic and functional problems in facial asymmetry, particularly in cases of retreatment.

Symposium Introduction: Studies of women and men in bed and in space

Science.gov (United States)

Hargens, Alan

INTRODUCTION: Some gender differences in response to microgravity have been noted previously. Furthermore current exercise systems for space flight do not provide loads equal to those on Earth. We hypothesized that supine LBNP treadmill exercise combined with flywheel resistive exercise maintains upright physiologic responses and tissue mass following 30-days and 60-days of head-down tilt (HDT) bed rest (BR). METHODS: For WISE-2005, 16 healthy women (age 25-40 years) underwent a 20-day baseline period, followed by 60-days continuous HDT (-6 degrees) BR and then by recovery for an additional 20-days. Women were assigned to either a control group (CON, n=8) who performed no exercise or to an exercise group (EX, n=8). EX subjects performed a 40-min, variable intensity (40-80 RESULTS: For WISE-2005, post-BR orthostatic tolerance (time to pre-syncope) was signifi- cantly better in the EX group than that in the CON group (p¡ 0.05). On BR day 50, heart rate (HR) was elevated at supine rest for the CON, but not for EX. Moreover, during a supine LBNP stress test at 30 mmHg, the HR increase from Pre-BR to BR day 50 for the EX group was less than that for CON. Heart mass decreased significantly in CON, but increased signifi- cantly in EX. Post-BR upright VO2pk, muscle strength, and endurance decreased significantly in CON, but were preserved in EX. Post-BR bone resorption was greater than pre-BR in both groups. Helical peptide and N-telopeptide excretions increased in both CON and EX. However, bone-specific alkaline phosphatase, a bone formation marker, tended to be higher in EX than in CON. DISCUSSION AND CONCLUSIONS: Previously we found that orthostatic tolerance is lower in women than that in men. For WISE-2005, supine treadmill exercise protocol within LBNP along with flywheel resistive exercise maintains orthostatic responses, upright exercise capacity, heart mass, muscle strength and endurance during 60-days HDT BR. By comparison with previous studies, cardiac atrophy

2017-01-01

Full Text Available Biodiesel attracts most of the researchers and automotive industries in recent years as an alternative fuel for diesel engines, because of its better lubricity property, higher cetane number, and less greenhouse gas emissions. The use of bio diesel leads to reduction in hydro carbons, carbon monoxide, and particulate matter, but increase in NOx emissions. Increase in biodiesel blends in standard diesel leads to increase in NOx emission. In this study, an attempt is made to reduce the NOx emis-sions of a diesel engine fueled with pure soy methyl ester (B100 with low pressure steam injection. Experiments were carried out and studied for both standard diesel and pure biodiesel of soy methyl ester with steam injection ratio of 5, 10, and 15% on mass ratio basis of air in the inlet manifold. The present study has shown that around 30% reduction in NOx can be achieved for the steam injection rate of 10% and considerable reduction for all other steam injection rates when compared to standard diesel and B100. It is also observed that steam injection having signifi-cant impact on reduction of other emissions such as HC, CO, and CO2. The study also noted marginal improvement in the engine brake power, brake thermal effi-ciency and reduction in specific fuel consumption at part loads and minor increase during peak load operation for the low pressure steam injection on B100.

SERUM ANALYSIS OF AMYLOID BETA-PROTEIN 1-40 IN HEALTHY SUBJECTS, AUTISTIC CHILDREN AND ALZHEIMER’S PATIENTS

2008-06-01

Full Text Available Amyloid beta-protein1-40 (AP40 is a low molecu­lar weight peptide produced throughout life during normal cell metabolism and neurodegenerative diseases. Owing to its neurotrophic and neurotoxic effects, the present study was conducted to evalu­ate serum levels of AP40 in healthy subjects, au­tistic children and Alzheimer’s disease patients. Serum AP40 was measured by enzyme-linked im­munosorbent assay (ELISA. AP40 was signifi­cantly higher in normal children compared to nor­mal older controls, in normal children compared to autistic children, and in autistic children compared to Alzheimer’s patients (p value was less than 0.05 for all groups. This finding suggests an age-re­lated decline of serum AP40 in normal aging, as well as in autism and Alzheimer’s disease. This decline may result from abnormal processing of amyloid beta-protein precursor (APP during nor­mal aging and age-related diseases such as autism in children and Alzheimer’s disease in elderly. Possible explanations for this decline may include age-related increased interactions of AP40 with cytoskeletal proteins for brain tissue deposition, increased serine proteases for APP metabolism or hyperimmune reaction (antibodies to AP40 for removal of circulating AP40. To conclude, the AP40 metabolism declines with normal aging and in addition to its role in Alzheimer’s disease this protein might also be a contributing factor in au­tism.

2017-09-01

Full Text Available Statement of Problem: Previous studies have shown that exposure of dental amalgam fillings to MRI and mobile phones can increase microleakage of amalgam restorations. Objectives: The aim of this study was to evaluate the effects of exposure to radiofrequency radiation emitted from indoor Wi-Fi access devices on microleakage of amalgam restorations. Materials and Methods: Standard class V cavities were prepared on the buccal surfaces of 69 extracted human premolar teeth. The samples were divided into two exposure groups and one non-exposed control group of 23 teeth each. The specimens in the experimental groups were exposed to a radiofrequency (RF radiation emitted from a commercial 2.4 GHz Wi Fi router. The distance between the Wi-Fi router and samples was 30 cm and the router was exchanging data with a laptop computer that was placed 20 m away from the router. Teeth samples in the first exposure group (group A were exposed to RF for 3 days while the second exposure group (group B was exposed for 6 days. Then the teeth were sectioned and scored for microleakage under a stereomicroscope. Results: The score of microleakage was significantly higher in the exposure group A compared to that of the control group. However, the score of microleakage was not significantly different between the exposure group B and control group. Furthermore, the scores of microleakage was signifi-cantly higher in the exposure group A than that of the exposure group B. Conclusions: Exposure of patients with amalgam restorations to radiofre-quency waves emitted from commercial Wi-Fi routers can lead to in-creased microleakage of amalgam restorations.

Effect of directional selection for body size on fluctuating asymmetry in certain morphological traits in Drosophila ananassae.

Vishalakshi, C; Singh, B N

2009-06-01

Variation in the subtle differences between the right and left sides of bilateral characters or fluctuating asymmetry (FA) has been considered as an indicator of an organism's ability to cope with genetic and environmental stresses during development. However, due to inconsistency in the results of empirical studies, the relationship between FA and stress has been the subject of intense debate. In this study, we investigated whether stress caused by artificial bidirectional selection for body size has any effect on the levels of FA of different morphological traits in Drosophila ananassae. The realised heritability (h2) was higher in low-line females and high-line males, which suggests an asymmetrical response to selection for body size. Further, the levels of FA were compared across 10 generations of selection in different selection lines in both sexes for sternopleural bristle number, wing length, wing-to-thorax ratio, sex combtooth number and ovariole number. The levels of FA differed significantly among generations and selection lines but did not change markedly with directional selection. However, the levels of FA were higher in the G10 generation (at the end of selection) than G0 (at the start of selection) but lower than the G5 generation in different selection lines, suggesting that the levels of FA are not affected by the inbreeding generated during the course of selection. Also, the levels of FA in the hybrids of high and low lines were signifi cantly lower than the parental selection lines, suggesting that FA is influenced by hybridisation. These results are discussed in the framework of the literature available on FA and its relationship with stress.

2016-10-01

Full Text Available El debate sobre la integración de los extranjeros en Suiza, país multicultural en sus raíces y orígenes, se mantiene en una constante tensión frente a las corrientes proteccionistas y a las tendencias patrióticas, comunes a muchos rincones del planeta. Esos «otros», extraños extranjeros, que actúan diferentemente, difíciles de situar en cualquier sector de la sociedad, generan inquietud entre los nativos. En el caso de los expatriados por razones políticas, el  estatus de refugiado o de solicitante de asilo político representa una tarjeta de identidad pesada de transportar consigo. Una visión simplista ubica al demandante de asilo en el eje de la criminalidad y del narcotráfico. Se ignora la individualidad de los casos, así como la violencia en la que el propio sistema y las leyes del asilo político los someten. Frente a una política federal estrictamente cerrada en lo que a integración del solicitante del asilo concierne, el Cantón de Neuchâtel, terreno de análisis de nuestra investigación, se da un espacio de debate en cuanto a la necesidad de implicar a este grupo, demandantes de asilo, dentro de su dinámica social. Diversos sectores de la sociedad de Neuchâtel se movilizan a fin de contrarrestar las insuficiencias del sistema. Sin embargo, los obstáculos son múltiples y se suceden. La investigación que presentamos a continuación tiene como finalidad analizar las diversas acciones que se desarrollan en el Cantón de Neuchâtel en favor de la integración del  sector en cuestión y el impacto de éstas sobre dicho grupo. Nos hemos propuesto hacer un seguimiento del camino que recorre el demandante de asilo, a través de las diversas instituciones, a fin de conocer los esfuerzos y los obstáculos de esta gestión.

2012-10-02

Time series analysis of spaceborne synthetic aperture radar (SAR) data, GPS measurements, and fi eld observations reveal that the central section of the Izmit (Turkey) fault that slipped with a supershear rupture velocity in the A.D. 1999, Mw7.4, Izmit earthquake began creeping aseismically following the earthquake. Rapid initial postseismic afterslip decayed logarithmically with time and appears to have reached a steady rate comparable to the preearthquake full fault-crossing rate, suggesting that it may continue for decades and possibly until late in the earthquake cycle. If confi rmed by future monitoring, these observations identify postseismic afterslip as a mechanism for initiating creep behavior along strike-slip faults. Long-term afterslip and/or creep has signifi cant implications for earthquake cycle models, recurrence intervals of large earthquakes, and accordingly, seismic hazard estimation along mature strike-slip faults, in particular for Istanbul which is believed to lie adjacent to a seismic gap along the North Anatolian fault in the Sea of Marmara. © 2012 Geological Society of America.

He moved to the city in 1951 and founded, twenty-two years later, in 1973, what would be one of the biggest Universities in the state of Paraná, the Tuiuti. We analyze the channels of his social ascension, specifi cally the army, the politics, the personal relationships and the fi eld of the private education, aiming to understand the possibilities opened to the black people in a society that was suffering signifi cant modernizing changes. We explore some statistical data that indicate these changes and the “conservative ideology” expressed in the works of some local intellectuals since the 50`s. By doing so, we expect to make it possible to understand the meaning of the trajectory and of its vicissitudes in the specifi c local context and related to the broader discussions on the “racial relations” in Brazil.

As we know that Indonesia is a country with ethnic diversity but it aspires to the same goal, that is to the wealthy and prosperous society. Therefore, it becomes important to develop multicultural education, which is an educational process that gives equal opportunities to all children including minorities regardless of their differences in ethnicity, culture and religion, to strengthen the unity and integrity, national identity and the nation’s standing in  the international world. In this case, the school must design the learning process, preparing curriculum and evaluation design, as well as prepare teachers who have the multicultural perception, attitude and behavior, so that they becomes part of those make a signifi cant contribution to the development of multicultural attitude of the students.

Full Text Available Changes in red fox home range size in relation to environmental and intrinsic factors were studied using radio-telemetry during 2006–2008 in Ikh Nart Nature Reserve, southeastern Mongolia. We captured a total of 12 red foxes (8 females and 4 males and fi tted them with VHF radio-collars. Marked animals were tracked up to fi ve times a week to estimate home ranges. We also trapped small mammal and insects in different biotopes for 3 years to estimate relative abundance of prey. Our results showed that mean individual home range sizes varied widely and differed among years. There was variation in home ranges between adults versus juveniles, but no signifi cant difference was found between males versus females. In addition, mean home range size did not differ seasonally for pooled years. Variation in home ranges was best explained by a model that included covariates of year and age. We suggest that spatiotemporal changes in resource availability across years infl uenced home range dynamics of red foxes in our study.

However, it remains unknown whether gut bacteria perform functions during the progression of vibriosis. In this study, 16S rRNA gene amplicon sequencing was used to investigate temporal alteration of gut bacterial community in swimming crabs in response to 72-h V. alginolyticus challenge. Our results show that V. alginolyticus infection resulted in dynamic changes of bacterial community composition in swimming crabs. Such changes were highlighted by the overwhelming overabundance of Vibrio and a signifi cant fluctuation in the gut bacteria including the bacteria with high relative abundance and especially those with low relative abundance. These findings reveal that crab vibriosis gradually develops with the infection time of V. alginolyticus and tightly relates to the dysbiosis of gut bacterial community structure. This work contributes to our appreciation of the importance of the balance of gut bacterial community structure in maintaining the health of crustaceans.

Full Text Available An urgent issue for power plants operating on solid fuels (coal is the issue of utilization or use of accumulated production waste - ash and slag materials - in the related production. Ash-slag materials are classified as “waste”, usually grade 5; tens of millions of tons of them being pro-duced annually in the Kemerovo region, which threatens the ecology of the region. At the same time, ash and slag is a very promising raw material. The use of this material as a base for the final product allows us to signifi-cantly expand the possibilities of using coal. The most widespread is the system of ash and slag involving in construction or as a replacement for sand in road construction, or as an additive to building mixtures. However, there are both industrially valuable and environmentally dangerous ele-ments in ash-slag materials. Ash-slag materials can be considered as inde-pendent ore deposits located on the surface and requiring the costs of their extraction.

Full Text Available Phosphate reduction is of important industrial relevance in the manufacturing of emulsifi ed meat products because it may give rise to a healthier product. The eff ect of seven diff erent phosphate types was tested on the physicochemical and quality characteristics to select the most promising phosphate type for further cooked sausage manufacturing. Next, phosphate mass fraction was gradually reduced. Tetrasodium di- or pyrophosphate (TSPP and sodium tripolyphosphate (STPP increased pH, reduced structural properties, resulted in the highest emulsion stability, lowest cooking loss and had litt le eff ect on hardness. Based on the viscoelastic properties, a minimum mass fraction of 0.06 % TSPP was suffi cient to obtain an acceptable quality product. Rheology proved to be a very useful tool to evaluate the quality of meat products, as it gives insight in the structure of the meat product and especially the functional properties of meat proteins. Based on the obtained results, it can be concluded that the current amount of phosphate added to emulsifi ed meat products can be signifi cantly reduced with minimal loss of product quality.

Mutagenized populations have provided impor-tant materials for introducing variation and identifying gene function in plants. In this study, an ethyl methanesul-fonate (EMS)-induced soybean (Glycine max) population, consisting of 21,600 independent M2 lines, was developed. Over 1,000 M4 (5) families, with diverse abnormal pheno-types for seed composition, seed shape, plant morphology and maturity that are stably expressed across different environments and generations were identified. Phenotypic analysis of the population led to the identification of a yellow pigmentation mutant, gyl, that displayed signifi-cantly decreased chlorophyll (Chl) content and abnormal chloroplast development. Sequence analysis showed that gyl is allelic to MinnGold, where a different single nucleotide polymorphism variation in the Mg-chelatase subunit gene (ChlI1a) results in golden yellow leaves. A cleaved amplified polymorphic sequence marker was developed and may be applied to marker-assisted selection for the golden yellow phenotype in soybean breeding. We show that the newly developed soybean EMS mutant population has potential for functional genomics research and genetic improvement in soybean.

Full Text Available The aim of this paper is to evaluate themost effective way of tackling the urban informaleconomy. It has been recently argued that theconventional rational economic actor approach(which increases the costs of participating in theurban informal economy so that they outweighthe benefi ts should be replaced or complementedby a social actor approach which focusesupon improving tax morale. To evaluate the effectivenessof these supposedly alternative approachesto tackling the participation of urbanpopulations in the informal economy, we reportthe results of face-to-face interviews conductedin 2013 with 17,886 urban dwellers across the 28Member States of the EU. Multilevel logistic regressionanalysis reveals that both approachesare effective in signifi cantly reducing the urbanpopulation’s participation in the informal economy.When tax morale is high, however, the rationaleconomic actor approach of increasing thecosts has little impact on reducing the probabilityof engagement in the informal economy. The paperconcludes by calling for greater emphasis onimproving the tax morale of the urban populationso as to tackle the informal economy in the urbanareas of Europe and beyond.

Full Text Available The article considers the value of preventive management in modern conditions. The global fi nancial and economic crisis of 2008-2010. sharpened interest in the problems of crisis management. This interest is manifested at the level of individual businesses, and at the level of the economy as a whole. At the same time revealed a signifi cant drawback: the development of crisis management theory lags behind practice. Non-compliance of the existing theory to modern requirements leads to the fact that the known approaches are not based on theoretical positions and empirical evidence and best practices, and, consequently, do not diff er systematically, because of this requires further research in this direction. The analysis shows that crisis management is a complex control system, which has its own specifi c features.

Full Text Available Effect of compost tea on mycelial growth and disease severity of Fusarium oxysporum f. sp. radicis-lycopersici. Simultaneous addition, on culture media, of Fusarium oxysporum f. sp. radicis-lycopersici and compost teas revealed that the latest induced the inhibition of the mycelial growth of the pathogen. This inhibition, noted after an incubation period of about six days at 25°C, was more important when compost teas were enriched in PDB (Potato Dextrose Broth, where it may reach 70% compared to the control. Transplantation of tomato seedlings, previously inoculated by a conidial suspension of F. oxysporum f. sp. radicis-lycopersici, in a container media (peat, perlite or the mixture of the two substrates treated by compost teas has signifi cantly reduced Fusarium crown and root rot incidence compared to inoculated and untreated control seedlings. Disease incidence is more reduced when tomato inoculated plants are transplanted in peat treated by compost teas; indeed, these plants donʼt show any wilting and present a vigorous root system and a better vegetative growth.

Salivary glands are very susceptible to radiation and any disturbances in their function are detrimental to the hard tissues in the oral cavity. The aim of this study was to evaluate posterior class V dental caries in patients with head and neck cancers undergoing radiotherapy. In this study, twenty seven patients undergoing conventional radiotherapy were included. Class V dental caries of posterior teeth in these patients were evaluated in three intervals: before treatment, 3 weeks after the initiation of the treatment, and at the end of the treatment. Differences of mean caries activity between intervals were evaluated using paired sample t-test. There were no class V decays prior to radiotherapy. Mean percentage of class V caries three weeks after radiotherapy and at the end of radiotherapy were 28.42% ± 14.41 and 67.05% ± 19.02, respectively. There were statistically signifi-cant differences in mean values among three stages (P = 0.00025). The results of the present study re-vealed that radiotherapy in patients with head and neck cancers causes class V dental caries on posteri-or teeth.

Full Text Available "Restingas" are herbaceous/ shrubby coastal sand-dune habitats that cover great areas of Brazil, particularly along the Bahia state coast. The restingas are disturbed and are under strong pressure, mainly in northeastern Brazil. Fragmentation of the landscape and habitat loss within natural ecosystems are the factors which are mainly responsible for reduction of species diversity by extinction events. The goal of the present study was elucidate whether the conservation status of restinga habitats on the northern coast of Bahia state was interfering with microhabitat use by the endemic lizard Tropidurus hygomi. The results showed that the use of microhabitat resources by T. hygomi did not have any signifi cant differences in the four areas we chose for study. However, diverse factors of degradation were found to contribute indirectly to its habitat loss. The T. hygomi lizard is a generalist in its use of restinga microhabitats, and probably due the endemic condition, its conservation status is linked directly to conservation of the restinga habitats on the northern coast of Bahia state.

We investigate theoretically and experimentally the static magnetic properties of single crystals of the molecular-based single-chain magnet of formula [Dy(hfac)3NIT(C6H4OPh)]∞ comprising alternating Dy3+ and organic radicals. The magnetic molar susceptibility χM displays a strong angular variation for sample rotations around two directions perpendicular to the chain axis. A peculiar inversion between maxima and minima in the angular dependence of χM occurs on increasing temperature. Using information regarding the monomeric building block as well as an ab initio estimation of the magnetic anisotropy of the Dy3+ ion, this “anisotropy-inversion” phenomenon can be assigned to weak one-dimensional ferromagnetism along the chain axis. This indicates that antiferromagnetic next-nearest-neighbor interactions between Dy3+ ions dominate, despite the large Dy-Dy separation, over the nearest-neighbor interactions between the radicals and the Dy3+ ions. Measurements of the field dependence of the magnetization, both along and perpendicularly to the chain, and of the angular dependence of χM in a strong magnetic field confirm such an interpretation. Transfer-matrix simulations of the experimental measurements are performed using a classical one-dimensional spin model with antiferromagnetic Heisenberg exchange interaction and noncollinear uniaxial single-ion anisotropies favoring a canted antiferromagnetic spin arrangement, with a net magnetic moment along the chain axis. The fine agreement obtained with experimental data provides estimates of the Hamiltonian parameters, essential for further study of the dynamics of rare-earth-based molecular chains.

Sarcoidosis is endemically prevalent in Northern Europe, but gender differences among the sarcoidosis population have not yet been compositely addressed. To reveal independent factors that formulate gender differences in the presentation of sarcoidosis. All Caucasian patients with confirmed sarcoidosis were recruited from the outpatient department of the Lung Clinic of the Tartu University Hospital, Estonia, between February 2009 and April 2011. Data on demographics, complaints, symptoms, clinical presentation, extrapulmonary manifestations, radiographic stage, lung function parameters and sarcoidosis-related laboratory indices were all drawn from patients' clinical records at presentation. Factors characteristic of female gender were estimated using multivariate logistic regression analysis. Of 230 cases included, there were significantly more females (56.5%, P = 0.005). After adjustment for age, females appeared distinguishable from males by older age [adjusted odds ratio (OR) 1.04, 95% confidence interval (CI) 1.02-1.07], less frequent smoking (OR 0.25, 95% CI 0.13-0.49), higher probability of extrapulmonary complaints (OR 2.06, 95% CI 1.16-3.65) and musculoskeletal sarcoidosis (OR 3.22, 95% CI 1.65-6.29), and after adjustment for both age and smoking status lower forced expiratory volume in 1 s and lung carbon monoxide diffusing coefficient % predicted (OR 0.89, 95% CI 0.82-0.97 and OR 0.98, 95% CI 0.96-0.995, respectively), but by higher forced vital capacity % predicted (OR 1.12, 95% CI 1.03-1.22). Women with sarcoidosis are independently characterized by greater airflow obstruction, lower lung diffusing coefficient, older age, less smoking, and more frequent extrapulmonary complaints and musculoskeletal involvement. This may urge special attention when addressing female patients in both differential diagnostic and management settings. © 2014 John Wiley & Sons Ltd.

A new nickel phosphate KNi3[PO3(F,OH)]2[PO2(OH)2]F2 has been synthesized using a modified hydrothermal method. Structural characterizations show that it adopts a 3D framework structure with 2D layers of Ni octahedra in a stair-case Kagomé lattice. The Ni2 octahedron at the inversion center shares two trans-faces with Ni1 octahedra to form a linear trimer (Ni3O8F6) as the basic structural unit. The Ni-trimers are linked between themselves by sharing F-corners and to [PO3(F,OH)] tetrahedral groups by sharing O-corners to form 2D stair-case Kagomé layers, which are parallel to the (100) plane and are stacked along the a-axis. Successive Kagomé layers are combined together by [PO2(OH)2] tetrahedral groups and interstice cations K+. Magnetic measurements reveal that KNi3[PO3(F,OH)]2[PO2(OH)2]F2 exhibits a canted antiferromagnetic ordering with a ferromagnetic component at low temperatures.

Full Text Available Transforming growth factor β1 (TGF-β1 plays a key role in the development of the immune response, as well as in the process of liver regeneration. Measuring the level of TGF-β1 may have important clinical implications in liver transplantation, because cytokine concentration in the tissue and in blood plasma varies with different liver diseases. Aim. To analyze the dynamics of TGF-β1 levels in children-recipients with liver transplant from related donors, including from incompatible blood groups.Materials and methods. The study involved 127 children aged 3 to 72 months (median – 8, average age – 12 ± 14 months, including 57 boys and 70 girls, with liver cirrhosis, developed as the result of congenital and hereditary diseases of the hepatobiliary system. All patients underwent transplantation of the left lateral liver sector from living related donors: 98 patients were transplantedfragment of a liver from identical or AB0-compatible donors and 29 – from incompatible donors. The concentration of TGF-β1 was determined by enzyme immunoassay method in blood plasma samples.Results. Average level of TGF-β1 in blood plasma of children with liver cirrhosis, developed as the result of congenital and hereditary diseases of the hepatobiliary system was 5,2 ± 5,5 ng/ml. A month after liver transplantation from a related donor level of TGF-β1 in blood plasma of recipients increased to 8,1 ± 9,6 ng/ml. One year after transplantation, the average level of TGF-β1 in the recipients of liver fragment was 7,7 ± 8,4 ng/ml, and signifi cantly (p = 0,00 differed from the level prior to transplantation. No association between TGF-β1 level in a month and a year after transplantation and the compatibility of the recipient with AB0 donor was found. A correlation (r = –0,23, p < 0,05 between level of TGF-β1 prior to transplantation and the development of graft dysfunction was observed: in recipients with graft dysfunction (16 cases

Distortion product otoacoustic emissions: comparison of sequential vs. simultaneous presentation of primary tones.

Science.gov (United States)

Kumar, U Ajith; Maruthy, Sandeep; Chandrakant, Vishwakarma

2009-03-01

Distortion product otoacoustic emissions are one form of evoked otoacoustic emissions. DPOAEs provide the frequency specific information about the hearing status in mid and high frequency regions. But in most screening protocols TEOAEs are preferred as it requires less time compared to DPOAE. This is because, in DPOAE each stimulus is presented one after the other and responses are analyzed. Grason and Stadler Incorporation 60 (GSI-60) offer simultaneous presentation of four sets of primary tones at a time and checks for the DPOAE. In this mode of presentation, all the pairs are presented at a time and following that response is extracted separately whereas, in sequential mode primaries are presented in orderly fashion one after the other. In this article simultaneous and sequential protocols were used to compare the Distortion product otoacoustic emission amplitude, noise floor and administration time in individuals with normal hearing and mild sensori-neural (SN) hearing loss. In simultaneous protocols four sets of primary tones (i.e. 8 tones) were presented together whereas, in sequential presentation mode one set of primary tones was presented each time. Simultaneous protocol was completed in less than half the time required for the completion of sequential protocol. Two techniques yielded similar results at frequencies above 1000 Hz only in normal hearing group. In SN hearing loss group simultaneous presentation yielded signifi cantly higher noise floors and distortion product amplitudes. This result challenges the use of simultaneous presentation technique in neonatal hearing screening programmes and on other pathologies. This discrepancy between two protocols may be due to some changes in biomechanical process in the cochlear and/or due to higher distortion/noise produced by the system during the simultaneous presentation mode.

We can notice higher presence of kyphotic deformity at the probationers of male population that it is the case with female population while the higher presence of lordotic deformity is at female population.The highest number of probationers have reported that none of the proffesors warn them about proper sitting. The measures inside the groups sorted by gender qualifi cation, indicate on high percentage of both boys and girls who are not warned on proper sitting. Also, inside the groups of improper body holders, we can notice the most signifi cant kyphotic and lordotic deformity in the category of students who are never warned to sit properly. These indicators report us that is necessary to invest much more work on the education of parents and children as well as school stuff at the preschool and school institutions which would result in reducing the appearence and development of postural deformity at the population who is more liable to transformations of such kind.

Full Text Available 【Abstract】Objective: This research analyzes data on road traffic accidents (RTA in Fars province, whose roads are among the highly dangerous ones in Iran. It inves- tigates educational level and age involved in RTA in order to discover patterns that can prevent or decrease accidents. Methods: This research made use of data visualization techniques to find hidden patterns. The data included mor- tality rate related to RTA in Fars province and were obtained from Fars Forensic Medicine Registry covering a period of 1 year from March 21, 2010 to March 21, 2011. All data were analyzed using SPSS 11.5. The results were reported as de- scriptive indices such as frequency (percentage. The Chi- square test was applied to the data concerning educational level and age. P value less than 0.05 was considered significant. Results: In the mentioned period, 1 831 people were killed, out of whom un/lowly educated people (69.6% ac- counted for the highest mortality rate. The significant rela- tionship between educational level and mortality rate was found (X2=275.98, P<0.0001. Also three was a significant association between age and mortality rate (X2=371.20, P<0.0001. Young people (age between 20 and 29 years contribute to higher RTA mortality rate compared with other age groups. Conclusion: The educational level and age are signifi- cantly correlated to mortality rate. The youth and un/lowly educated people suffer more fatal RTA.

The Motivational Effects of Gender, Residency, Worldview, and Acculturation Towards Science Study at American Institutes of Higher Education

Science.gov (United States)

Doppke, Max George

This non-experimental, quantitative exploratory study examined the relationship between genders, student residency status, acculturation, worldviews, and the motivation towards science education for a group of 291 undergraduate students in the United States. As all demographic variables were nominal, and all survey variables were ordinal, associations and differences utilized non-parametric statistical procedures. The overall design was descriptive, comparative, and correlational. Spearman's rho signified that there was a moderate positive correlation between the total scores on the Worldview Analysis Scale (WAS) and the total scores on the Science Motivation Questionnaire-II (SMQ-II; rs = .393, *pAnalysis Scale (WAS) and the Science Motivation Questionnaire-II (SMQ-II) to determine if differences in score were based on gender. The WAS score was statistically significantly higher in males (Median = 180.00) than in females ( Median = 164.00, U = 8521.500, z = -2.840, p = .005). . The SMQ-II score was statistically insignificantly higher in males (Median = 152.56) than in females (Median = 140.08, U = 9652.500, z = -1.263, p = .207). In following the fundamental dictates of social research, this study offered a thorough description of a situation that ultimately provokes various possible explanations as necessary conclusions to intellectually stimulating thought, without the burden of propagating dubious inferences through unwarranted deterministic or probabilistic causality. Recommendations for future work include mixed-method studies with interviews, longitudinal studies, instructor-student studies, and gender vs. sexual orientation studies.

Role of the circulation on the anthropogenic CO2 inventory in the North-East Atlantic: A climatological analysis

Climatology-based storage rate of anthropogenic CO2 (Cant, referred to year 2000) in the North-East Atlantic (53 ± 9 kmol s-1, 0.020 ± 0.003 Pg-C yr-1) is described on annual mean terms. Cant advection (32 ± 14 kmol s-1) occurs mostly in the upper 1800 m and contributes to 60% of the Cant storage rate. The Azores and Portugal Currents act as 'Cant streams' importing 389 ± 90 kmol s-1, most of which recirculates southwards with the Canary Current (-214 ± 34 kmol s-1). The Azores Counter Current (-79 ± 36 kmol s-1) and the northward-flowing Mediterranean Water advective branch (-31 ± 12 kmol s-1) comprise secondary Cant export routes. By means of Cant transport decomposition, we find horizontal circulation to represent 11% of the Cant storage rate, while overturning circulation is the main driver (48% of the Cant storage rate). Within the domain of this study, overturning circulation is a key mechanism by which Cant in the upper layer (0-500 dbar) is drawdown (74 ± 14 kmol s-1) to intermediate levels (500-2000 dbar), and entrained (37 ± 7 kmol s-1) into the Mediterranean Outflow Water to form Mediterranean Water. This newly formed water mass partly exports Cant to the North Atlantic at a rate of -39 ± 9 kmol s-1 and partly contributes to the Cant storage in the North-East Atlantic (with up to 0.015 ± 0.006 Pg-C yr-1). Closing the Cant budget, 40% of the Cant storage in the North-East Atlantic is attributable to anthropogenic CO2 uptake from the atmosphere (21 ± 10 kmol s-1).

Stoop, Patricia

2014-06-01

Full Text Available The Augustinian convent of Jericho in Brussels was one of the main centres of textual, literary, and spiritual culture in the late medieval Low Countries. In addition to the large collection of manuscripts which the canonesses wrote for themselves, the sisters produced several books for people and institutions outside the convent walls. Thus the sisters were both important recipients as well as signifi cant producers of texts. This article will focus on the question of the origin of the texts and books that the sisters used to build their library. Additionally, attention will be paid to the external recipients of the books that the Jericho scribes made, in order to shed light on the as yet understudied exchange of texts and books to and from (female convents and the literary networks in which these religious institutions functioned.El convento de las agustinas Jericó en Bruselas fue uno de los centros más importantes de la cultura textual, literaria, y espiritual en los Países Bajos durante la Baja Edad Media. Además de la amplia colección de manuscritos que las canonesas escribieron para sí mismas, produjeron varios libros para personas e instituciones externas al convento. Las religiosas no solo eran receptoras importantes, sino también signifi cativas productoras de textos. El artículo se concentra en la cuestión de la proveniencia de los textos y libros que servían para crear su biblioteca. Se prestará asimismo atención a los destinatarios externos a los que se dirigieron las copistas de Jericó con el fin de arrojar luz sobre la hasta ahora poco estudiada dinámica de intercambio de textos y libros entre conventos (de mujeres y el exterior y las redes literarias en el marco de las cuales esas instituciones religiosas funcionaron.

Full Text Available The experiment was conducted at the School of Veterinary Medicine and Zootechnils, Federal University of Tocantins, in order to verify the effects of four nitrogenous manuring levels (0, 30, 60 and 120kg.ha-1 and different spacings (0.25, 0.35, 0.45 and 0.65m on plant size, biomass and dry mass in the production of millet (Pennisetum glaucum L.. The experimental design consisted of complete blocks, with 16 treatments and four replications in a 4x4 factorial arrangement to form a total of 64 experimental units, each of 9m². The plant sizes and accumulation of biomass and dry matter were estimated weekly starting from 14 days after seeding. For the highest nitrogen level (120kg.ha-1, the biomass and dry mass production were also the highest. There were no signifi cant differences between the spacings utilized and the plant sizes at any of the phenological stages evaluated. However, the dry mass production was distinct, considering that the spacing of 0.25m presented the highest values, followed by the 0.35m, 0.45m and 0.65m spacings.

Full Text Available Hybrid coordination systems (marketing cooperatives and contracts are in place in agriculture to link smallholder farmers to the global agri-food value chains. With the framework of transaction cost economics, this study, however, is particularly designed to investigate the key determinants pushing dairy farmers to hybrids (marketing cooperatives and contracts, viz. spot market channels in the local food chains. A household survey of 415 smallholder dairy farmers was designed. Data collection was administered using trained enumerators. A multinomial logistic regression model was employed to analyze data and to identify the signifi cant determinants. The results indicate that high transaction costs and resource constraints were found driving farmers to cooperative engagement and contracts, implying that hybrids were found to be a solution to farmers’ constraints of access to information and institutional absence, as well as resource constraints. Policy makers and development partners are advised to strengthen cooperative societies and contract enforcement mechanisms. Providing information and resources to increase smallholders’ capacity with resources appear to be interventions which will enable the agricultural marketing system to properly function by serving smallholders in linking to the global food chains.

2012-11-01

Full Text Available In recent years culture has become one of the most studied topicsin project management research. Some studies have investigatedthe infl uence of culture at different levels – such as nationalculture, industry culture, organisational culture and professionalculture. As a project-based industry, the construction industryneeds to have more insight concerning cultural issues at theproject level and their infl uence on the performance of constructionprojects. Few studies, however, have focused on culture at theproject level. This paper uses a questionnaire survey to determinethe perceptions of Chinese contractors about the impact of projectculture on the performance of local construction projects. This isaugmented by a series of in-depth interviews with senior executivemanagers in the industry. The fi ndings indicate that specifi c projectculture does contribute signifi cantly towards project outcomes.In particular, goal orientation and fl exibility, as two dimensionsof project culture, have a negative statistical correlation withperceived satisfaction of the process, commercial success, futurebusiness opportunities, lessons learnt from the project, satisfactionwith the relationships, and overall performance. This paper alsoindicates that the affordability of developing an appropriate projectculture is a major concern for industry practitioners.

Full Text Available Considering that there are few success chances for isolated businesses, public-private partnerships represent the basis of tourism businesses’ sustainable development, aiming to attract increasing numbers of visitors in tourism destinations. Within this context, the main aim of the present paper is to identify tourism stakeholders’ intentions to participate in public-private partnerships for a sustainable tourism development of urban destinations. Focused on the increased importance of partnerships between tourism stakeholders, with the common goal of sustainable tourism development, a survey was conducted among the tourism service providers from the Romanian urban destination, Braşov. The research results outline the defi ciencies in the analyzed destination, which lead to a low notoriety of the destination’s management and marketing organization among local tourism stakeholders. In addition, the results show a low level of involvement of tourism operators in supporting the collaboration efforts of this organization. Based on the research results, a theoretical model was proposed for the identifi cation of the signifi cant factors which infl uence local stakeholders’ intentions to participate in public-private partnerships for a sustainable tourism development.

Full Text Available In the era of technology, the demand of the software development increases at a very high speed, as software has touched the human’s life in all aspects. The better quality software development acquiring minimum development time leads to the team work in which a group of people has been formed that work together in a team for the software development. One of the most signifi-cant issues in effective and efficient teamwork is the team leader selection because the team lead-er is the person in any team that is going to handle all types of managerial activities such as lead-ership, motivation to others, etc. The team leader selection process may be dependent on numer-ous conflicting selection indexes that make it a Multi-Criteria Decision Making (MCDM prob-lem. In the present research, an MCDM approach namely, Euclidean Distance Based Approxi-mation (EDBA which is based on the calculation of the composite distance value for each alter-native from a hypothetical optimal point is presented. The result of this study provides a compre-hensive ranking of team leaders that leads to the right selection of team leader in information technology (IT sector.

This study set out to explore the ways in which social media can facilitate learning in medical education. In particular we were interested in determining whether the use of Twitter during an academic conference can promote learning for participants. The Twitter transcript from the annual International Conference on Residency Education (ICRE) 2013 was qualitatively analysed for evidence of the three overarching cognitive themes: (1) preconceptions, (2) frameworks, and (3) metacognition/refl ection in regard to the National Research Council ’ s (NRC) How People Learn framework . Content analysis of the Twitter transcript revealed evidence of the three cognitive themes as related to how people learn. Twitter appears to be most effective at stimulating individuals ’ preconceptions, thereby engaging them with the new material acquired during a medical education conference. The study of social media data, such as the Twitter data used in this study, is in its infancy. Having established that Twitter does hold signifi cant potential as a learning tool during an academic conference, we are now in a better position to more closely examine the spread, depth, and sustainability of such learning during medical education meetings.

Elena GORI

2018-02-01

Full Text Available This paper aims to analyze the role of Italian local authorities in disseminating gender equality by using the gender mainstreaming approach. Previous researches in gender were concentrated on legal aspect linked to labor or to violence against women. Moreover, other studies examined the effects of EU funds on local gender policies. However, no research results are provided about methodologies, timing and responsibilities set up by local administrations. The research focuses on a population consisting of local authorities representing the principal regional towns and analyzes the Italian local authorities’ commitment in gender mainstreaming. The result of the analysis is that the local authorities are demonstrating more commitment with policies linked to employment issues. Moreover, Italian municipalities show a signifi cant commitment to spreading GM policies, not only dedicated to women but also to a more inclusive concept of ‘gender’. However, we argue that policies for gender equality are not target-driven: local authorities widespread a wide range of gender policies without defi ning an adequate tool. Policy makers need to refl ect about the possibility to develop a clear frame concerning strategies, resources, measuring and impact indicators in order to issue real ‘gender effective policies’.

Full Text Available Intra Aortic Balloon Pump (IABP is the most commonly used mechanical circulatory assist device in cardiac patients. IABP can improve ventricular function by decreasing the preload and increasing systolic output with signifi-cant improvement in myocardial oxygen supply/demand ratio. Pre-operative IABP therapy in ′high-risk′ coronary patients has been shown to reduce hospital mortality and shorten ICU stay significantly, compared with controls. The introduction of sheathless insertion kits has reduced the incidence of vascular complication rates. Pro-Active Counter Pulsation is a new IABP system which automatically detects the irregular pattern and result is an improvement in the haemodynamic effect of IABP during periods of arrhythmia. Today, continued improvements in IABP technology permit safer use and earlier intervention to provide haemodynamic support. These developments have made the IABP a mainstay in the management of ischemic and dysfunctional myocardium. This review article aims to provide basic concept of IABP to hospital doctors especially anaesthetists, intensivists cardiologists and cardiac surgeons. It discusses the common indications, contraindications, the physiologic aspects of IABP, the equipment needed to facilitate IABP, the use of the IABP in special situations and complications of its use.

Full Text Available Purpose: The aim of this paper was to investigate determinants of choosing negotiation strategies in simulation and board games. Methodology: The authors decided to use the standardized interview to get fi rst-thought answer fast. As respondents group of students from the Faculty of Management, University of Warsaw was chosen. Findings: Research material confi rms that confrontational strategy is the most popular one which was usually justifi ed by the actions of the opponents. Some of the participants took into their considerations also personal value hierarchy and the results of previous games. Nevertheless almost all students declared that their approach to negotiations was cooperative as well as integrative. Negotiators usually do not consider negotiations as a holistic process with a variable sum of winnings but they tend to focus rather on their own result. Moreover, distributive or confrontational negotiations are so strongly rooted in participants’ consciousness that abandoning this pattern requires a signifi cant theoretical and empirical knowledge on confl ict management. Originality: The paper is unique in terms of application of board games for defi ning determinants of the strategy-setting in negotiation games.

The high lithological diversity and monocline structure have addressed the Quaternay glaciation. The paper studies the glacial evolution by mean of the glacial features and the objective is to know the temporal evolution and extent of Quaternary glaciers and to establish as accurate as possible correlations with the other Cantabrian massifs. A geomorphological map to scale 1/25,000, ELA calculation of each glacier and glacial period, and a morphostrtigraphical analysis, including aspect, front altitudes, glaciers lenght and ELA have been made. Eleven glaciers systems have been reconstructed, defining in the North side tongues longer than 5 km and a medium altitude of fronts of 1120 m a.s.l. The moraine complex point to between one and four glacial stages in each valley. Four glacial stages have been establish: two of alike extent (F1 and F2, a retreated and equilibrium stage (F3 and a marginal glacial stage defined by small cirque glacier (F4 and extreme periglacial processes (rock glaciers, block slopes, block streams and stratified debris. Finally, the glacial stages have been correlated with known absolute dating of other massif of the Cantabrian Mountain.La Sierra de Cebolleda constituye 10 km de la divisoria cantábrica, en dirección E-W, al sur de los Picos de Europa, el macizo más alto de la cordillera.

Relatively rapid reemergence of anthropogenic carbon (Cant) in the Equatorial Pacific is of potential importance for its impact on the carbonate buffering capacity of surface seawater and thereby impeding the ocean's ability to further absorb Cant from the atmosphere. We explore the mechanisms sustaining Cant reemergence (upwelling) from the thermocline to surface layers by applying water mass transformation diagnostics to a global ocean/sea ice/biogeochemistry model. We find that the upwelling rate of Cant (0.4 PgC yr-1) from the thermocline to the surface layer is almost twice as large as air-sea Cant fluxes (0.203 PgC yr-1). The upwelling of Cant from the thermocline to the surface layer can be understood as a two-step process: The first being due to diapycnal diffusive transformation fluxes and the second due to surface buoyancy fluxes. We also find that this reemergence of Cant decreases dramatically during the 1982/1983 and 1997/1998 El Niño events.

Full Text Available Level of affi nity between grapevine rootstock and Vitis vinifera as scion, quality of reproductive materials and technological actions in grapevine rootstock production process determine success in grapevine rootstock production in large extent. Practical training showed that difference in level of compatibility between grapevine rootstock and grafted Vitis vinifera cultivars are existing. Direct effects of these differences are unequal yield of fi rst class grafted grapevine rootlings. In this paper, level of compatibility in nursery between clones of cv. Chardonnay BCL 75, VCR4 and cv. Merlot R18, MCL 519 and grapevine rootstocks Kober 5BB (Vitis berlandieri x V. riparia, SO4 (V. berlandieri x V. riparia and 41B (Chasselas x V.berlandieri were investigated. The trial was conducted in commercial grapevine nursery located in Velika Drenova, Serbia. As an index of compatibility, grade of high quality grapevine grafted rootlings, dry matter in mature shoots and root system development were used. Grafting was done by `tongue grafting` indoor technique. Stratifi cation was done in sand, on temperature of the stratifi cation material of 26-28oC, and humidity of around 90%. Grafted cuttings were waxed twice: before stratifi cation, and before planting in the nursery. Grafted rootlings were classed in two classes according to regulations of quality, (Yugoslav Offi cial Register, 26/79. Grafted rootlings that did not satisfi ed standard criteria were discarded. Both clones of cv. Chardonnay gave the highest percentage of I class grafted rootlings on grapevine rootstock 41B: clone BCL 75 – 60% and clone VCR4 – 61%. In the same combination, those grapevine grafted rootlings had the highest weight of the root system. Lower percentage of obtained I class grafted rootlings was established on rootstock Kober 5BB, while statistically signifi cantly lower yields were obtained on grapevine rootstock SO4: clone BCL75 – 43% and clone VCR4 – 48%.

After an initial IT to identify AT, the volunteers participated in three experimental sessions on three different days: 20 minutes’ of cycling at either 90 or 110% of AT, and a control session (CON. Blood glucose was measured at rest, and at the 10th and 20th minutes of exercise or control condition, as well as every 15 minutes during a 2-hour postexercise recovery period (Rec. One-way ANOVA did not detect significant differences in blood glucose levels between the sessions at 90 and 110% of AT. Compared to CON, a signifi cant decrease was observed at the 20th minute of exercise, and at the 15th and 60th minutes of Rec from the 90% AT session. Significant reductions were also observed at the 10th and 20th minutes of exercise and at the 15th, 30th, 45th, 60th and 90th minutes of Rec from the session at 110% AT. Exercise performed at the higher intensity (110% AT resulted in a tendency of a more pronounced and prolonged hypoglycemic effect during and after exercise, and may be an alternative intensity for glycemic control in type 2 diabetics who do not have cardiovascular complications or other contraindications to exercising at intensities above the AT.

Full Text Available Systemic heparinization during continuous renal replacement therapy (CRRT is associated with disadvantage of risk of bleeding. This study analyses the efficacy of frequent saline flushes compared with heparin anticoagulation to maintain filter life. From January 2004 to November 2007, 65 critically ill patients with acute renal failure underwent CRRT. Continuous venovenous hemodialfiltration (CVVHDF was performed using Diapact Braun CRRT machine. 1.7% P.D. fluid was used as dialysate. 0.9% NS with addition of 10% Ca Gluconate, Magnesium Sulphate, Soda bicarbonate and Potassium Chloride added sequentially in separate units were used for replacement, carefully monitoring their levels. Anticoagulation of extracorporeal circuit was achieved with unfractionated heparin (250-500 units alternate hour in 35 patients targeting aPTT of 45-55 seconds. No anticoagulation was used in 30 patients with baseline APTT > 55 seconds and extracorporeal circuit was maintained with saline flushes at 30 min interval. 65 pa-tients including 42 males. Co-morbidities were comparable in both groups. HMARF was signifi-cantly more common in heparin group while Sepsis was comparable in both the groups. CRRT parameters were similar in both groups. Average filter life in heparin group was 26 ± 6.4 hours while it was 24.5 ± 6.36 hours in heparin free group ( P=NS. Patients receiving heparin had 16 bleeding episodes (0.45/patient while only four bleeding episodes occurred in heparin free group (0.13/patient, P< 0.05. Mortality was 71% in heparin group and 67% in heparin free group. Frequent saline flushes is an effective mode of maintainance of extracorporeal circuit in CRRT when aPTT is already on the higher side, with significantly decreased bleeding episodes.

Women Athletes: Re-signifying the Female Body?

Miriam Adelman

2003-01-01

Full Text Available How does women’s participation in sport contribute to the re-signification of women’s corporality? Considering Susan Brownmiller’s notion that femininity, in modern society, can be understood as an “aesthetic of limitation”, I also work with notions of gender and corporality taken from recent work by Susan Bordo and Judith Butler, in an attempt to identify changes in women’s practices and representations of the female body propitiated by sporting activity. I analyze the testimonies of Brazilian women athletes, most of whom can be considered professionals, from two sporting fields: on the one hand, equestriennes engaged in the elite sport of showjumping, and on the other, women involved in the popular sport of volleyball. I also look at cultural images of women athletes as currently produced in mass media. he evidence that I obtain through field work leads me to identify conflicting tendencies of “deconstruction” of certain aspects of the above-mentioned aesthetics of limitation and persistent cultural concern for women’s “masculinization” through sport.

Full Text Available One of the basic conditions of the economical success in milk production is the high and periodic reproduction of the cows. That means the parturition of a healthy calf from every cow per a year. The development and level of reproduction functions is very susceptible to the quantity and mainly quality of nutrition. The insuffi ciency in nutrition is strongly related to the fertility. The aim of this study was to evaluate the reproduction indicators depending upon the level of the milk yield and body condition of the Holstein cows at the family-owned farm. The basic dataset was obtained during the years 2004 – 2007. The milk yield and fertility data were gained from the herd records. The extreme values were removed from the basic set. Body condition score was evaluated every month. The groups according to the milk yield level and body condition score were evaluated. The basic statistical characteristics were determined in the groups of cows and in the evaluated sets. The effect of particular factors was proved by the one-factorial analysis of variance ANOVA. Increasing milk yield in the groups with milk yield up to 7000 kg of milk, 7000-8000 kg and more than 8000 kg had negative impact on the reproduction indicators. The differences in the length of calving to fififi rst service interval among particular groups were statistically signifififi cant (P ≥ 0.01. The average length of this interval was 96, 111 and 122 days for 1st, 2nd and 3rd group, respectively. In addition, the average length of calving to conception (service period interval was 154, 165 and 171 days. There were found no signifi cant differences in numbers of services per conception. The average BCS at calving was 3.59 points. After calving BCS level decreased till the 6th month of lactation, where its level 2.43 points, then the BCS level increased. Average BCS level at conception was under 2.5 points. The variation of BCS during the lactation was 2 points.

Full Text Available The purpose of the study was to identify driving and limiting factors of farm management in a region of fragmented agriculture. The paper presents the results of the research conducted in the South-Eastern Poland (Macroregion of Małopolska and Pogórze. The survey was conducted in 2014 in the farms managed by young farmers, i.e. the benefi ciaries of the measure “Setting up of young farmers” from the RDP 2007–2013, with the use of a survey method with a questionnaire interview. The research was empirical, and its main goal was to present a case study of the farm management by young farmers in terms of specifi c management barriers. The results of the studies pointed to the fragmented agrarian structure as the one of the biggest barriers of the eff ective farm management. The young farmers pointed that fragmented agrarian structure signifi cantly impedes the purchase or lease of agricultural land, and the farm development in the same way. The survey pointed to the factors that contribute to the young farmers: the entrepreneurial attitude, activity and creativity, training, the management knowledge and better access to the Common Agricultural Policy instruments.

The Bohai Sea is a low-lying semi-enclosed sea area that is linked to the Yellow Sea via the Bohai straits (mixed zone). Its off shore seabed is shallow, which makes it vulnerable to serious marine meteorological disasters associated with the northward passage of Pacifi c tropical cyclones. Analyses on data of remote sensing and buoy of the mixed zone of the Yellow and Bohai seas indicate that all the wind speed, signifi cant wave height, and salinity (SAL) increased, sea surface temperature decreased, and wind energy density changed considerably during the passage of tropical cyclone Matmo on July 25, 2014. It was found that the SAL inversion layer in the mixed zone of the Yellow and Bohai Seas was caused by the tropical cyclone. Furthermore, it was found that the tropical cyclone transported the northern Yellow Sea cold water mass (NYSCWM) into the mixed zone of the Yellow and Bohai Seas. The NYSCWM has direct infl uence on both the aquaculture and the ecological environment of the region. Therefore, further research is needed to establish the mechanism behind the formation of the SAL inversion layer in the mixed zone, and to determine the infl uence of tropical cyclones on the NYSCWM.

Full Text Available Sixteen Aspergillus niger aggregate isolates collected from different crop fi elds were subjected to RAPDPCR using 20 Operon primers and 8 synthetic primers. Twenty-two primers led to the amplifi cation of 727 fragments ranging from 3500 bp (OPA 11 to 200 bp (primer 06. Two bands were monomorphic, while the rest were polymorphic. Three amplicons produced by OPA 16 were recorded as isolate-specifi c as 2300 bp by AnC2 and AnR3, and as 2800 bp by AnC2 only. The highest genetic similarity (0.79 was measured between AnC2 and AnR3, and the lowest (0.17 between AnC2 and AnR2. Multivariate analysis of genetic similarity revealed three major clusters, named group I, group II and group III. All isolates were ochratoxin A negative (<1 ng g-1. Isolates AnC2 and AnR3, which produced HCN and solubilized the greatest amount of phosphorus, belonged to group I. These isolates also signifi cantly increased eggplant yield and caused the greatest inhibition of colonization by R. solani in dual culture. They also suppressed the root rot on eggplant and the soil population of R. solani in pot soil.

Full Text Available This article analyses the development of single-person living arrangements amongst unmarried people aged between 65 and 84 years old who did not live with a partner between 1991 and 2001 in seven European countries (Spain, France, Greece, Hungary, Portugal, Romania and Switzerland. To do so, census micro data provided by IPUMS (Integrated Public Use Microdata Series were used. The role of fi ve variables with regard to the probability of living alone versus living with others was examined. It was investigated whether the observed development was due to changes in the population composition. Logistic regression was used as a standardisation technique with the census data. Results showed that, after controlling for all the variables, the observed regional patterns remain the same, and that the proportion of elderly living alone increased in 2001 in all countries but Romania where, if the population composition had not changed, this proportion would have diminished. The demographic structure (by gender, age and marital status did not signifi cantly modify the observed proportions either over time or at a regional level. In contrast, the variations of the structure regarding the socio-economic variables (educational level and employment status were key to explain part of the observed change.

Full Text Available The Chinese economic model, which paved the way to «Chinese economic miracle» is running out of its capabilities. The new generation of leadership led by Xi Jinping is facing an extremely complicated task that can be compared to the one Deng Xiaoping had solved at the turn of 1980’s – to elaborate a new model of development. Measures adopted by the new General secretary of the CPC Central Committee in order to concentrate powers and to strengthen personal power are justifi ed by the need to change political course. However, as a result of these steps, the system of institutional authoritarianism that for the past 40 years was being created and provided economic success to China has been signifi cantly demolished. Current challenges for China originate not only from the necessity to change the economic model, but also from the reaction of the authorities to this need. Amidst uncertainty of new reference points for the reforms, lack of obvious competitive advantages, strengthening of external challenges and deep changes in Chinese society, China has again appeared on the verge of serious challenges, the answer to which will help evaluate the effectiveness of the reforms not only from socio-economic but also from a historical perspective.

Full Text Available One of the consequences of global warming in the Caribbean is an increase in thefrequency and intensity of hurricanes. Little is known on the impact of this naturalphenomenon on forests, particularly for dry tropical forests. Understanding this impactin terms of structure and species richness is important for forest management. Slowmoving Hurricane Beta, a category 1, struck Old Providence island, Colombia, inOctober 29, 2005. Before Beta woody vegetation was characterized by 88 2 x 50 mplots (0.01 ha established throughout the island following the protocol by Gentry(1982; 59 plots were studied fi ve years earlier and 29 plots four to fi ve monthsearlier. The impact of hurricane Beta was assessed within 11 plots located in the DryTropical Forests of Old Providence, six months after the hurricane. The These plotswere measured in species composition, diameter at breast height (DBH, and heightwere measured within these plots. There was a considerable reduction in the numberof individuals, stems, height, basal areas, and there was no signifi cant differencebetween DBH. Height damage was positively associated with increasing DHB class.Furthermore, based on the results of species richness, even after controlling for thedifferent number of individuals, through rarefaction, there was no major differencebefore and after Beta.

Methods: Between November 2011 and April 2014, PDTs were performed on 32 severe brain injury patients in ICU by a team of physicians and intensivists. The success rate, effi cacy, safety, and complications including stomal infection and bleeding, paratracheal insertion, pneumothorax, pneumomediastinum, tracheal laceration, as well as clinically significant tracheal stenosis were carefully monitored and recorded respectively. Results: The operations took 4-15 minutes (mean 9.1 minutes±4.2 minutes. Totally 4 cases suffered from complications in the operations: 3 cases of stomal bleeding, and 1 case of intratracheal bloody secretion, but none required intervention. Paratracheal insertion, pneumothorax, pneumomediastinum, tracheal laceration, or clinically signifi cant tracheal stenosis were not found in PDT patients. There was no procedure-related death occurring during or after PDT. Conclusion: Our study demonstrats that PDT is a safe, highly effective, and minimally invasive procedure. The appropriate sedation and airway management perioperatively help to reduce complication rates. PDT should be performed or supervised by a team of physicians with extensive experience in this procedure, and also an intensivist with experience in diffi cult airway management.

In practice, managers cannot and do not want to apply all of these metrics and managers’ choice does not necessarily rely on what theory emphasizes as their advantages and disadvantages. We surveyed 64 CFOs in order to explore the corporate practice in the Republic of Serbia. The DCF-based capital budgeting metrics are dominant compared to the traditional metrics, and the one that is used the most is the profi tability index, only to be followed by the IRR and the NPV. The Payback Period is yet frequently used. The earnings-based corporate performance metrics are still the most important. However, the presence of EVA and balanced scorecard is not negligible. Large companies use them signifi cantly more than small companies. The orientation towards EVA and balanced scorecard increases with the internationalization of a fi rm as well. Finally, companies using sophisticated capital budgeting metrics are prone to using sophisticated corporate performance metrics.

Sacerdos vs. Episcopus. The employment of the Treatise de septem ordinibus ecclesiae by Isidore of Seville (a source study

Full Text Available The aim of this article is to reveal the methods and characteristic features of Isidore of Seville’s interpretation of the anonymous text De septem ordinibus ecclesiae (5th — early 7th centuries. This text, traditionally attributed to St. Jerome, deals with the functions of church servants and clerics. Isidore reinterprets it in the second part of his book De ecclesiasticis offi ciis, also devoted to the origin and functions of clerics. Isidore often makes use of the text of his predecessor but almost never quotes the borrowed sentences completely and unchanged. The text of Ps.-Jerome was used by Isidore as a set of rhetorical patterns which he needed in order to express his own ideas. Thus, Isidore reinterprets the concept of sacerdos: in his text it is, fi rst of all, the bishop. Besides, Isidore fi lls the image of the bishop with new content; it is signifi cant that Isidore uses only the prologue from Ps.-Jerome’s text, rather than a specifi c chapter devoted to bishops. Isidore’s sacerdos, as opposed to the episcopus of Ps.-Jerome, is actively involved in the life of the Christian community: he preaches, instructs the fl ock, gives alms, takes part in legal proceedings and performs the sacraments.

Full Text Available TLarge-scale defense system projects are strategic for maintaining and increasing the national defense capability. Therefore, governments spend billions of dollars in the acquisition and development of large-scale defense systems. The scale of defense systems is always increasing and the costs to build them are skyrocketing. Today, defense systems are software intensive and they are either a system of systems or a part of it. Historically, the project performances observed in the development of these systems have been signifi cantly poor when compared to other types of projects. It is obvious that the currently used systems development life cycle models are insuffi cient to address today’s challenges of building these systems. Using a systems development life cycle model that is specifi cally designed for largescale defense system developments and is effective in dealing with today’s and near-future challenges will help to improve project performances. The fi rst step in the development a large-scale defense systems development life cycle model is the identifi cation of requirements for such a model. This paper contributes to the body of literature in the fi eld by providing a set of requirements for system development life cycle models for large-scale defense systems. Furthermore, a research agenda is proposed.

The combination of graphene with conductive nanoparticles, forming graphene–nanoparticle hybrid materials, offers a number of excellent properties for advanced engineering applications. A novel and simple method was developed to deposit 10 wt% tin-doped indium tin oxide (ITO) nanoparticles on graphene. The method involved a combination of a solution-based environmen-tally friendly electroless deposition approach and subse-quent vacuum annealing.A stable organic-free solution of ITO was prepared from economical salts of In(NO3)3?H2O and SnCl4. The obtained ITO nanostructure exhibited a unique architecture, with uniformly dispersed 25–35 nm size ITO nanoparticles, containing only the crystallized In2O3phase.The synthesized ITO nanoparticles–graphene hybrid exhibited very good and reproducible optical transparency in the visible range (more than 85%) and a 28.2% improvement in electrical conductivity relative to graphene synthesized by chemical vapor deposition.It was observed that the ITO nanoparticles affect the position of the Raman signal of graphene,in which the D,G,and 2D peaks were redshifted by 5.65, 5.69, and 9.74 cm-1,respectively, and the annealing conditions had no signifi-cant effect on the Raman signatures of graphene.

Full Text Available The karyotypes of Chorthippus ( Megaulacobothrus aethalinus (Zubovsky, 1899 and Chorthippus ( Megaulacobothrus chinensis Tarbinsky, 1927 were compared by means of the conventional cytogenetic method. The results showed that chromosome numbers of two species were 2n( ♂ =17=16+XO, in which three pairs of autosomal and sex chromosomes were terminal chromosomes, and the other fi ve pairs of autosomal ones were metacentric chromosomes, which are the diagnostic characters of Chorthippus . However, these two species could be identifi ed by the different formulae and the relative length of chromosomes. The chromosome formula of Chorthippus (M. aethalinus is K(2n, ♂ =6m+11t=6L+6M+4S+XO, whereas that of Chorthippus (M. chinensis is K(2n, ♂ =6m+11t=6L+8M+2S+XO. In addition, we found that the location and the relative length of sex chromosomes in the two species were different from each other. Sex chromosome of Chorthippus (M. aethalinus located at fi fth position and its relative length was equal to 8.33%, whereas that of Chorthippus (M. chinensis was at eighth position and its relative length was equal to 5.53%. These results showed that signifi cant different karyotype features exist in the two compared species of Chorthippus .

The sample was composed of 255 participants of both sexes (109 women and 146 men, aged 14-18 (M =15.97, DE = 1.18, who attended different schools in Buenos Aires province. In order to get the information, it was used: a the Index of Empathy for children and teenagers (Frías, Mestre, Perez and Samper, 1999; b the gratitude scale corresponding to the Questionnaire of Positive Emotions for teenagers (Schmidt, 2005 and c the Assertive Behavior scale (Michelson, Sugay, Wood and Kasdin, 1987. The results from MANO-VAs (Multivariate analysis of variance show that both sympathy and gratitude influence signifi- cantly teenager’s social behavior. Participants with high sympathy and gratitude show more assertive behaviors and less aggressive strategies in their social re- lationships. It corroborates the hypothesis that empathic emotion can enhance the development and performance of socially skilled behavior. Nevertheless, is important to note that this relation may not be unidirectional, but those positive emotions can enhance assertive behavior and this, in turn, provide feedback for positive emotional experience as it is expressed by the model of rising spiral by Fredrickson (Fredrickson, 2002.

Full Text Available This work evaluated the inclusion of phytase in diets with reduced nonphytate phosphorus (NPP levels in relation to the performance and carcass yield of broilers and litter characteristics. The experimental design was completely randomized in a 2 x 3 factorial arrangement – two phytase levels (0 and 25U/kg and three NPP levels (100, 85 and 70% of the requirement, in a total of six treatments with fi ve replicates. The reduction of the NPP to 70% of the requirement decreased the weight gain and feed intake and increased the feed:gain ratio. Phytase inclusion increased the weight gain and the feed intake at 21 days. The NPP x phytase interaction was signifi cant with regard to the weight gain at 42 days. The reduction of NPP to 70% diminished the feed intake at 42 days and increased the liver and heart relative weight. Nitrogen content was lower in the litter of broilers fed diets with phytase and decreased phosphorus content, due to the NPP reduction in the diets. It was concluded that diets with 85% of NPP, supplemented with 25U/kg of phytase, can be used with no negative effect on performance or carcass and litter characteristics.

The Phenomenon of Trust in Flat Owners’ Collective Renovation Strategies in Estonia

2015-12-01

Full Text Available Mobilising fl at owners into renovating residential blocks in post-socialist countries has been a complicated process. Evidence from Estonia shows that the success of collective renewal strategies depends not only on economic issues but also on ways investments are organised and, signifi cantly, the relationship of trust between diff erent actors. The paper aims at conceptualising the issue of institutional trust upon the experience of urban housing renewal in Estonia. It is contended that trust is crucial for the joint decision-making in a block as well as for facilitating negotiations between fl at owners’ associations, local municipalities and market actors. The paper draws on three qualitative studies conducted in Estonia during the 2000s, which allow asserting that trust towards new strategies of housing renewal can be achieved and maintained by ‘best practices’, which by concentrating expert knowledge also denote direct communication between experts and fl at owners. While it is important to raise the residents’ technical knowledgeability, it is indispensable to develop abilities to manage and communicate the renovation process between diff erent parties. The public sector is conceived to be a central actor in sustaining trust between actors who have no previous positive experience from collective residential strategies

Full Text Available Termite are known to infest building in the tropics, but in their quest for cellulose they may also cause signifi cant damage to crops and trees. They become pest only when their natural habitat is altered in some way by humans. Subterranean termite Coptotermes spp has been known as the most economically important structural pest in Indonesia. Due tomorphological ambiguity, traditional identifi cation of Coptotermes spp. has always been diffi cult and unreliable. In economic point of view, economic loss due to termite attack always increases every year, and in the year 2000 it is estimated to reach 373 million US$. Moreover, the social as well as ecological impact caused by termite attack should also be considered. In the capital city of Jakarta, the subterranean termite attack on home buildings reaches around 55%; while in Surabaya (East Java 36%; and in Semarang (Central Java 41%. Meanwhile, in some other cities, the subterranean termite attack on home buildings reaches on the average of 20%. The presence of termites in a region can depend on various factors, such as soil and vegetation type. Climatic features andwater avaibility play an important part in termite survival. Daily and seasonal changes in these factors also affect termite distribution.Keywords: characteristics, climatic, Coptotermes spp, attack impact.

This study assessed the potential therapeutic benefi t of using HandTutor™ in combination with traditional rehabilitation in a post-stroke sub-acute population. The study compares an experimental group receiving traditional therapy combined with HandTutorTM treatment, against a control group receiving only traditional therapy. An assessor-blinded, randomized controlled pilot trial, was conducted in the Reuth rehabilitation unit in Israel. Thirty-one stroke patients in the sub-acute phase, were randomly assigned to one of the two groups (experimental or control) in sets of three. The experimental group (n = 16) underwent a hand rehabilitation programme using the HandTutorTM combined with traditional therapy. The control group (n = 15) received only traditional therapy. The treatment schedules for both groups were of similar duration and frequency. Improvements were evaluated using three indicators: 1) The Brunnström-Fugl-Meyer (FM) test, 2) the Box and Blocks (B&B) test and 3) improvement parameters as determined by the HandTutorTM software. Following 15 consecutive treatment sessions, a signifi cant improvement was observed within the experimental group (95% confi dence intervals) compared with the control group: B&B p = 0.015; FM p = 0.041, HandTutor™ performance accuracy on x axis and performance accuracy on y axis p stroke hand function rehabilitation.

Full Text Available In this study physicochemical and quality traits of biceps femoris and longissimus thoracis muscles of male and female Iranian one-humped camel were determined during 14 days of refrigeration storage. Analysis of variance of the results showed that only shear force and temperature were affected by the gender (p<0.05. Anatomical location of the muscle influenced the meat properties except for drip loss (p<0.05. Also, except for cooking loss, ageing influenced the physicochemical and quality properties of meat; during 14 days of storage, proteolysis resulted in an increase of L* and b* values, drip loss and myofibrillar fragmentation index, and the decrease of a* value, expressed juice, shear force and sarcomere length. Proteome changes (myofi brillar proteins during storage were investigated. Gel analysis revealed that 19 protein spots were signifi cantly changed during 24, 72 and 168 h post-mortem. Fifteen spots were identified by MALDI-TOF/TOF mass spectrometer. Correlation analysis revealed significant correlations of actin, troponin T, capping protein, heat shock proteins (HSP and desmin with physicochemical and quality properties of meat (p<0.05. Actin might be a potential protein marker for colour, tenderness and water-holding capacity, and HSP27 and desmin are good candidate markers for colour and tenderness, respectively.

Full Text Available This article aims to shed light on the diffi culties encountered by students as readers of scientifi c texts in a foreign language, in this case in German. The focus of study lies on the perspectives of three Portuguese students-teachers in initial training who participated in activities for the development of their receptive textual competence in the context of the German didactic seminars held over two semesters at the Faculty of Letters of the University of Porto (FLUP. The work was conceived as a qualitative study to collect what the study participants thought and felt about their readings of scientifi c texts written in German. Data were obtained from a questionnaire, protocols of retrospection, verbal protocols and a semi-structured interview at the end. The results obtained by comparing the three cases, revealed that students found signifi cant diffi culties, not only in relation to the texts as specific academic documents, but also for themselves as readers, identifying knowledge gaps and a lack of habit in the processing of these types of texts. Based on these results, the aim is, ultimately, to equate the most appropriate teaching performance to the characteristics of these students and the texts to be read

BRCA1 Expression is an Important Biomarker for Chemosensitivity: Suppression of BRCA1 Increases the Apoptosis via Up-regulation of p53 and p21 During Cisplatin Treatment in Ovarian Cancer Cells

Full Text Available BRCA1 is a tumor suppressor which plays a crucial role in the repair of DNA double-strand breaks, and its abnormality is responsible for hereditary ovarian cancer syndrome. It has recently been reported that reduced expression of BRCA1 is also common in sporadic ovarian carcinoma via its promoter hypermethylation, and that ovarian carcinoma patients negative for BRCA1 expression showed favorable prognosis. To address if BRCA1 expression plays a role in the chemotherapeutic response, we analyzed the effect of BRCA1 suppression on the sensitivity to cisplatin and paclitaxel in ovarian cancer cells. Specific siRNA for BRCA1 gene was transfected into 3 ovarian cancer cell lines with various p53 status. Reduced expression of BRCA1 by transfection of BRCA1-siRNA resulted in a 5.3-fold increase in sensitivity to cisplatin in p53-wild A2780 cells, but not in p53-mutated A2780/CDDP and p53-deleted SKOV3 cells. Regarding the sensitivity to paclitaxel, BRCA1 suppression caused no significant changes in all the 3 cell lines. For ionizing radiation sensitivity, BRCA1 suppression also showed a significant higher sensitivity in A2780 cells. Growth curve and cell cycle analyses showed no signifi cant differences between BRCA1-siRNA-transfected A2780 cells and control cells. However, cisplatin treatment under suppression of BRCA1 showed a significantly increased apoptosis along with up-regulation of p53 and p21 in A2780 cells. Accordingly, reduced expression of BRCA1 enhances the cisplatin sensitivity and apoptosis via up-regulation of p53 and p21, but does not affect the paclitaxel sensitivity. Expression of BRCA1 might be an important biomarker for cisplatin resistance in ovarian carcinoma.

Full Text Available Considering the fact that one of the most fundamental tasks of training is developing motoric dimensions of sportsmen, the common goal of this work was to achieve relevant knowledge on the infl uence of ten-day-skiing course on students`* development and to establish their level. The special aim of this work was diagnosing the amount of some of the students` motoric abilities. According to the subjects, problems and goal of the research, there was a hypothesis put: motoric and morphological dimensions of students are coherent with their chrono logical growth and development ten-day-skiing course has signifi cant infl uence on developing some of the students` motoric abilities Besides remaining, the choice of examined samples was put under limits of organizational capacities for realizing researching procedure.It was necessary to insure required devices and standardized conditions under which planned research was supposed to be realized. The sample is taken from students` population implied in regular skiing course. Examined sample consists of thirty male students, each of which is twenty years old. Because of technical and organizational reasons it was not possible to diagnose the whole motoric range of tested students. Due to that a specifi c selection of tests was done and only six variables (that reliably predict levels of motoric abilities on which the training affects were taken: foot tapping, medicine ball throwing, pull-ups with undertaking, trunk lifting in 60 seconds and deep forward band. The level of students` motoric abilities after ten-day-skiing course is on a higher level then initial measuring, and we can certainly claim that it is the result of programmed training process during skiing course. According to the data gained from control and fi nal measuring you can fi nd out the effects of applied resources towards initial measuring.

The complete content of the program was conducted in the territory of the city of Kragujevac in several elementary schools, comprising 299 students of the 5th grade and their parents. The object of this study was to determine the number of students with defi cient kyphotic and lordotic body posture, to determine the presence of dis arrangements depanding on the gender and to determine the presence of kyphotic and lordotic deformity depanding on the parents level of information about defi ciant body posture among children. Kyphotic deformity of the examiners of male population is mostly present in the group of parents who are poorly informed about body posture defi ciency. Regarding examiners of female population , the presence of deformation is equally divided on the group of parents who expressed themselves as being very well, those who are undecided and those who are poorly informed. The more signifi cant presence of kyphotic deformity is at examiners of male population than at the examiners of female population while the higher presence of lordotic deformity is at the examiners of female population. Regarding female population we can observe the highest presence of deformation in the group of parents who are undecided while the other groups are very equabal by the presence of deformation. Stated measures impose a statement that it is necessary to continuosly work on both - children education and parents education aiming to recognize posture defi ciency and physical deformation of school and preschool population and all of this with the object of reducing the deformation and on time detecting certain disarrangements and taking adaquate measures for its senctuary

Full Text Available Abstract Electronic health records serve multiple purposes, including clinical communication, legal documentation, financial transaction capture, research and analytics. Electronic signatures attached to entries in EHRs have different logical and legal meanings for different users. Some of these are vestiges from historic paper formats that require reconsideration. Traditionally accepted functions of signatures, such as identity verification, attestation, consent, authorization and non-repudiation can become ambiguous in the context of computer-assisted workflow processes that incorporate functions like logins, auto-fill and audit trails. This article exposes the incompatibility of expectations among typical users of electronically signed information.

The growth of the craniofacial skeleton takes place from the 3(rd) week of intra-uterine life until 18 years of age. During this period, the craniofacial complex is affected by extrinsic and intrinsic factors which guide or alter the pattern of growth. Asymmetry can be encountered due to these multifactorial effects or as the normal divergence of the hemifacial counterpart occurs. At present, an orthodontist plays a major role not only in diagnosing dental asymmetry but also facial asymmetry. However, an orthodontist's role in treating or camouflaging the asymmetry can be limited due to the severity. The aim of this research is to report a technique for facial three-dimensional (3D) analysis used to measure the progress of nonsurgical orthodontic treatment approach for a subject with maxillary asymmetry combined with mandibular angular asymmetry. The facial analysis was composed of five parts: Upper face asymmetry analysis, maxillary analysis, maxillary cant analysis, mandibular cant analysis, and mandibular asymmetry analysis which were applied using 3D software InVivoDental 5.2.3 (Anatomage Company, San Jose, CA, USA). The five components of the facial analysis were applied in the initial cone-beam computed tomography (T1) for diagnosis. Maxillary analysis, maxillary cant analysis, and mandibular cant analysis were applied to measure the progress of the orthodontics treatment (T2). Twenty-two linear measurements bilaterally and sixteen angular criteria were used to analyze the facial structures using different anthropometric landmarks. Only angular mandibular asymmetry was reported. However, the subject had maxillary alveolar ridge cant of 9.96°and dental maxillary cant was 2.95° in T1. The mandibular alveolar ridge cant was 7.41° and the mandibular dental cant was 8.39°. Highest decrease in the cant was reported maxillary alveolar ridge around 2.35° and in the mandibular alveolar ridge around 3.96° in T2. Facial 3D analysis is considered a useful adjunct

Full Text Available INTRODUÇÃO: A malária é uma doença endêmica na Amazônia Legal Brasileira, apresentando riscos diferentes para cada região. O Município de Cantá, no Estado de Roraima, apresentou para todo o período estudado, um dos maiores índices parasitários anuais do Brasil, com valor sempre maior que 50. O presente estudo visa à utilização de uma rede neural artificial para previsão da incidência da malária nesse município, a fim de auxiliar os coordenadores de saúde no planejamento e gestão dos recursos. MÉTODOS: Os dados foram coletados no site do Ministério da Saúde, SIVEP - Malária entre 2003 e 2009. Estruturou-se uma rede neural artificial com três neurônios na camada de entrada, duas camadas intermediárias e uma camada de saída com um neurônio. A função de ativação foi à sigmoide. No treinamento, utilizou-se o método backpropagation, com taxa de aprendizado de 0,05 e momentum 0,01. O critério de parada foi atingir 20.000 ciclos ou uma meta de 0,001. Os dados de 2003 a 2008 foram utilizados para treinamento e validação. Comparam-se os resultados com os de um modelo de regressão logística. RESULTADOS: Os resultados para todos os períodos previstos mostraram-se que as redes neurais artificiais obtiveram um menor erro quadrático médio e erro absoluto quando comparado com o modelo de regressão para o ano de 2009. CONCLUSÕES: A rede neural artificial se mostrou adequada para um sistema de previsão de malária no município estudado, determinando com pequenos erros absolutos os valores preditivos, quando comparados ao modelo de regressão logística e aos valores reais.INTRODUCTION: Malaria is endemic in the Brazilian Amazon region, with different risks for each region.

Discussion and Conclusion: The results indicate that the simultaneous DO yields more better frontal lip cant change between both halves than the mono-DO with orthognathic surgery. The mean change is much higher in the simultaneous DO cases indicating a more effective correction and desired result. The biological reason and lip musculature mechanism behind the response in both conditions are discussed.

Background The results from the published studies on the association between angiotensin-converting enzyme (ACE) insertion/deletion (I/D) gene polymorphism and the treatment response to steroid in Asian children with idiopathic nephrotic syndrome (INS) is still conflicting. This meta-analysis was performed to evaluate the relation between ACE I/D gene polymorphism and treatment response to steroid in Asian children and to explore whether ACE D allele or DD genotype could become a predictive marker for steroid responsiveness. Methodology/Principal Findings Association studies were identified from the databases of PubMed, Embase, Cochrane Library and CBM-disc (China Biological Medicine Database) as of September 1, 2010, and eligible investigations were synthesized using meta-analysis method. Five investigations were identified for the analysis of association between ACE I/D gene polymorphism and steroid-resistant nephrotic syndrome (SRNS) risk in Asian children and seven studies were included to explore the relationship between ACE I/D gene polymorphism and steroid-sensitive nephrotic syndrome (SSNS) susceptibility. Five investigations were recruited to explore the difference of ACE I/D gene distribution between SRNS and SSNS. There was no a markedly association between D allele or DD genotype and SRNS susceptibility or SSNS risk, and the gene distribution differences of ACE between SRNS and SSNS were not statistically significant. II genotype might play a positive role against SRNS onset but not for SSNS (OR = 0.51, P = 0.02; OR = 0.95, P = 0.85; respectively), however, the result for the association of II genotype with SRNS risk was not stable. Conclusions/Significance Our results indicate that D allele or DD homozygous can't become a significant genetic molecular marker to predict the treatment response to steroid in Asian children with INS.

Full Text Available Analyzes that granite AE signal parameters under uniaxial loading by that way of Pearson linear correlation, research that correlation of characterization parameters within that separate group with various characteristics, and analyzes that relationship between each parameter and destruction. This study shows that: impact, events and ringing are mainly used to describe the damage degree of rock, amplitude characteristics, time characteristics and frequency characteristics are mainly used for acoustic emission source properties, and energy characteristics can not only be used to describe the damage degree of rock, but also be used to analyze the acoustic emission source. That ringing counts are highly interrelated with energy, intensity, duration, RMS and ASL have high correlation, a high correlation is in the three parameters of the energy characteristics, and there is a higher correlation between the two parameters of the timing characteristics. The correlation between the parameters of frequency is very low, and the acoustic emission parameters can't be replaced for each other in analysis, which need separate analysis. Characteristics of ringing and energy can be a very good description of failure, but failure precursors can't be quantized. However, the amplitude, RMS, ASL, can quantify characterization of that precursor of failure, such as the effective voltage value 0.7 V as the precursor of destruction, the emergence of amplitude exceeding 95 dB as that destructive precursor. The relationship between the timing characteristics and damage is not obvious, so you can't use those parameters analysis that fracture of rocks. But those parameters can be used to describe AE source characteristics. The peak frequency, inverse frequency and the center frequency can't reflect AE source characteristics, and that average frequency and initial frequency can reflect AE source characteristics.

Prior studies have suggested self-blame and sense of guilt as important elements associated with the effects of childhood sexual abuse on adult survivors (Cantón-Cortés, Cantón, Justicia & Cortés, 2011). However, few studies have explored the potential impact of the sense of guilt on outcomes in child victims. This study examines the mediating role of avoidance coping on the relationship between sense of guilt and outcomes (anxiety and self-esteem) in sexually abused children. The sample consisted of 447 sexually abused children (319 girls and 128 boys) aged 6 to 12. Path analysis indicated that children with higher feelings of guilt about the abuse showed more anxiety and lower levels of self-esteem. Indirect effects also indicated that sense of guilt predicted avoidance coping, which in turn contributed to higher anxiety and lower self-esteem. This model, which fits the data well for both girls and boys, explains 24.4 % of the variance in anxiety and 11.2 % of the variance in self-esteem. Results suggest that sense of guilt is an important target for clinical intervention with sexually abused children.
