Evaluation of Satisfaction with Nursing Care of Patients Hospitalaized in Surgical Clinics of Different Hospitals

Today, two main approaches are prominent in the assessment of care quality. The first is the determination of care standards, and the other approach for quality-guarantee is the method of monitoring the patient satisfaction. The aim of this study is to determine the satisfaction levels of patients, who stayed in surgery clinics in different hospitals, with nursing care. The sample of the study consisted of 972 patients who accepted to participate in the research, were able to communicate, 18 of age and above and literate. The data were collected through “The Personal Information Form” and “The Newcastle Scale of Satisfaction with Nursing”. The data were assessed through percentage distribution, t-test, One-Way ANOVA test, Man-Whitney U Test and Kruskal Wallis variance analysis. The satisfaction levels of the patients in the research group have differed according to their age, marital status, educational background, profession, the hospital in which the patients stay, previous hospital experience and whether or not they had companions with them. It became evident that patients were generally satisfied with nursing services, however the satisfaction levels of patients staying in private hospitals were more than those of patients staying in public hospitals.
Physical limitations of antennas in a lossy medium

The dissipated power and the directivity of antennas in a homogeneous, lossy medium are systematically analyzed in this paper. The antennas are ideal and located inside a lossless sphere. In the lossy space outside the sphere, the electromagnetic fields are expanded in a complete set of vector wave functions. The radiation efficiency, the directivity, and the power gain are defined for antennas in a lossy medium, and the optimal values of these quantities are derived. Simple relations between the maximal number of ports, or channels, an antenna can use and the optimal directivity and gain of the antenna are presented.
A three-phase half-bridge cascaded inverter with reduced number of input DC supply

Cascaded multilevel inverters (MLI) have recently received much attention due to its ability to perform well in various high voltage and high power applications with high efficiency. Cascaded inverters are able to generate high voltage output by utilizing a number of low voltage DC supplies and switches of low blocking voltage rating, which make cascaded MLI a cost effective choice for high voltage/power applications. The main drawback of cascaded MLI is the requirement of large number of isolated DC sources particularly, for three phase applications where the number of required input DC sources is three times that of single phase structure. In addition to the extra cost it will incur, the use of large number of DC supplies within the inverter will significantly increase its physical size, and complicate the management of such large number of DC sources. This paper presents a new topology for three phase MLI with a minimum number of input DC supplies. Symmetric and asymmetric input DC supply modes are developed for the proposed topology. Simulation and experimental results are provided to assess the performance of the proposed MLI topology.
Assessing the genetic structure of Oryza glumaepatula populations with isozyme markers

To assess the genetic diversity and genetic structure parame ters, nine populations of Oryza glumaepatula from the Amazon biome, four from the Pantanal biome, and one collected at Rio Xingu, Mato Grosso, totaling 14 populations and 333 individuals were studied with isozyme markers. Six loci were evaluated showing a moderate allozyme variability ( A = 1.21, P = 20.7%, H o = 0.005, H e = 0.060). The populations from the Pantanal biome showed higher diversity levels than the Amazon biome. High genetic differentiation among the populations, expected for self-fertilizing species, was observed (F ST=0.763), with lower differentiation found among the Pantanal populations
Ocean‐atmosphere partitioning of anthropogenic carbon dioxide on centennial timescales

A theory for the ocean‐atmosphere partitioning of anthropogenic carbon dioxide on centennial timescales is presented. The partial pressure of atmospheric CO2 (PCO2) is related to the external CO2 input (ΔΣC) at air‐sea equilibrium by: PCO2 = 280 ppm exp(ΔΣC/[IA + IO/R]), where IA, IO, and R are the pre‐industrial values of the atmospheric CO2 inventory, the oceanic dissolved inorganic carbon inventory, and the Revelle buffer factor of seawater, respectively. This analytical expression is tested with two‐ and three‐box ocean models, as well as for a version of the Massachusetts Institute of Technology general circulation model (MIT GCM) with a constant circulation field, and found to be valid by at least 10% accuracy for emissions lower than 4500 GtC. This relationship provides the stable level that PCO2 reaches for a given emission size, until atmospheric carbon is reduced on weathering timescales. On the basis of the MIT GCM, future carbon emissions must be restricted to a total of 700 GtC to achieve PCO2 stabilization at present‐day transient levels.
Sea surface temperature variability in the central-western Mediterranean Sea during the last 2700 years: a multi-proxy and multi-record approach

Abstract. This study presents the reconstructed evolution of sea surface conditions in the central-western Mediterranean Sea during the late Holocene (2700 years) from a set of multi-proxy records as measured on five short sediment cores from two sites north of Minorca (cores MINMC06 and HER-MC-MR3). Sea surface temperatures (SSTs) from alkenones and Globigerina bulloides Mg / Ca ratios are combined with δ18O measurements in order to reconstruct changes in the regional evaporation–precipitation (E–P) balance. We also revisit the G. bulloides Mg / Ca–SST calibration and re-adjusted it based on a set of core-top measurements from the western Mediterranean Sea. Modern regional oceanographic data indicate that Globigerina bulloides Mg / Ca is mainly controlled by seasonal spring SST conditions, related to the April–May primary productivity bloom in the region. In contrast, the alkenone–SST signal represents an integration of the annual signal. The construction of a robust chronological framework in the region allows for the synchronization of the different core sites and the construction of “stacked” proxy records in order to identify the most significant climatic variability patterns. The warmest sustained period occurred during the Roman Period (RP), which was immediately followed by a general cooling trend interrupted by several centennial-scale oscillations. We propose that this general cooling trend could be controlled by changes in the annual mean insolation. Even though some particularly warm SST intervals took place during the Medieval Climate Anomaly (MCA), the Little Ice Age (LIA) was markedly unstable, with some very cold SST events mostly during its second half. Finally, proxy records for the last centuries suggest that relatively low E–P ratios and cold SSTs dominated during negative North Atlantic Oscillation (NAO) phases, although SSTs seem to present a positive connection with the Atlantic Multidecadal Oscillation (AMO) index.
Instructions for use Title Paradoxical Interventricular Septal Motion as a Major Determinant of Late Gadolinium Enhancement in VentricularInsertion Points in Pulmonary Hypertension

Background: This study investigated the major clinical determinants of late gadolinium enhancement (LGE) at ventricular insertion points (VIPs) commonly seen in patients with pulmonary hypertension (PH). Methods: Forty-six consecutive PH patients (mean pulmonary artery pressure $25 mmHg at rest) and 21 matched controls were examined. Right ventricular (RV) morphology, function and LGE mass volume at VIPs were assessed by cardiac magnetic resonance (CMR). Radial motion of the left ventricular (LV) wall and interventricular septum (IVS) was assessed by speckle-tracking echocardiography. Paradoxical IVS motion index was then calculated. Univariate and multivariate regression analysis were conducted to characterize the relationship between LGE volume at VIPs and PH-related clinical indices, including the paradoxical IVS motion index. Results: Mean pulmonary arterial pressure (MPAP) of PH patients was 3869 mmHg. LGE at VIPs was observed in 42 of 46 PH patients, and the LGE volume was 2.02 mL (0.47–2.99 mL). Significant correlations with LGE volume at VIPs were observed for MPAP (r = 0.50) and CMR-derived parameters [RV mass index (r = 0.53), RV end-diastolic volume index (r = 0.53), RV ejection fraction (r =20.56), and paradoxical IVS motion index (r = 0.77)]. In multiple regression analysis, paradoxical IVS motion index alone significantly predicted LGE volume at VIPs (p,0.001). Conclusions: LGE at VIPs seen in patients with PH appears to reflect altered IVS motion rather than elevated RV pressure or remodeling. Long-term studies would be of benefit to characterize the clinical relevance of LGE at VIPs. Citation: Sato T, Tsujino I, Ohira H, Oyama-Manabe N, Ito YM, et al.

Indoor angular profile measurements and channel characterization at the millimeter-wave band

This paper presents a power angle profile (PAP) measurement campaign at the millimetre-wave band. Angular profiles were measured in different indoor topographies such as offices, corridors and a residence. Detailed angle-of-arrival (AoA) shape factors were derived, describing the spatial properties of the millimeter wave channel. The measurement results were related to the site-specific environments and correlation between the propagation condition and the multipath channel structure was observed. Finally, from the measurement results, it is found that the PAPs can be modeled as a finite scatterer model with a direct component plus multipath arriving within a variable sector α.
The Impact of Workload on the Evolution of Hip Internal and External Rotation in Professional Baseball Players Over the Course of the Season

Background: Although restricted hip range of motion (ROM) is associated with an increased risk for injuries in baseball players, the evolution of hip ROM over the season remains undefined. Hypothesis: Hip ROM profiles would be symmetric between hips and positions (pitchers vs position players) but would decrease from preseason to postseason. Additionally, it was hypothesized that this decrease in motion would correlate with workload. Study Design: Cohort study; Level of evidence, 2. Methods: Bilateral hip ROM was assessed in 96 professional baseball players (54 pitchers, 42 position players) preseason and postseason. ROM comparisons were made between lead and trailing hips, pitchers and position players, and preseason and postseason measures. The change from preseason to postseason was correlated with player demographics and measures of workload for pitchers and position players. Results: Preseason hip ROM was symmetric between hips; however, pitchers demonstrated increased preseason lead hip internal rotation (IR) (P = .018) and bilateral hip total ROM (TROM) (P < .020) compared with position players. From preseason to postseason, position players lost 7° of external rotation (ER) (P ≤ .005 ). In pitchers, the loss of IR correlated with increased pitches (P = .016) and innings (P = .037), while the loss of ER (P = .005 ) and TROM (P = .014) correlated with increasing mean fastball velocity. Workload for position players did not correlate with motion loss. Conclusion: Symmetric hip ROM profiles should be anticipated in baseball players; however, pitchers may have increased preseason IR and TROM and postseason ER and TROM relative to position players. Although loss of motion correlated with workload in pitchers, this was not the case for position players. Hip motion should be monitored over the course of the season. This is particularly true for pitchers who lose IR as workload increases, which may place them at a greater risk for injuries.
Performance of the VLT Planet Finder SPHERE - II. Data analysis and results for IFS in laboratory

Aims. We present the performance of the Integral Field Spectrograph (IFS) of SPHERE, the high-contrast imager for the ESO VLT telescope designed to perform imaging and spectroscopy of extrasolar planets, obtained from tests performed at the Institut de Planetologie et d'Astrophysique de Grenoble facility during the integration phase of the instrument. Methods. The tests were performed using the instrument software purposely prepared for SPHERE. The output data were reduced applying the SPHERE data reduction and handling software, adding an improved spectral deconvolution procedure. To this aim, we prepared an alternative procedure for the spectral subtraction exploiting the principal component analysis algorithm. Moreover, a simulated angular differential imaging procedure was also implemented to estimate how the instrument performed once this procedure was applied at telescope. The capability of the IFS to faithfully retrieve the spectra of the detected faint companions was also considered. Results. We found that the application of the updated version of the spectral deconvolution procedure alone, when the algorithm throughput is properly taken into account, gives us a 5 sigma limiting contrast of the order of 5 x 10(-6) or slightly better. The further application of the angular differential imaging procedure on these data should allow us to improve the contrast by one order of magnitude down to around 7x10(-7) at a separation of 0.3 arcsec. The application of a principal component analysis procedure that simultaneously uses spectral and angular data gives comparable results. Finally, we found that the reproducibility of the spectra of the detected faint companions is greatly improved when angular differential imaging is applied in addition to the spectral deconvolution.
Purification of Single-Wall carbon nanotubes by heat treatment and supercritical extraction

Arc discharge is the most practical method for the synthesis of single wall carbon nanotubes (SWCNT). However, the production of SWCNT by this technique has low selectivity and yield, requiring further purification steps. This work is a study of purification of SWCNT by heat treatment in an inert atmosphere followed by supercritical fluid extraction. The raw arc discharge material was first heat-treated at 1250 °C under argon. The nanotubes were further submitted to an extraction process using supercritical CO2 as solvent. A surfactant (tributylphosphate, TBP) and a chelating agent (hexafluoroacetylacetone, HFA) were used together to eliminate metallic impurities from the remaining arc discharge catalysts. Analysis of Inductively Coupled Plasma-Atomic Emission Spectrometry (ICP-AES) showed an efficient removal of iron and cobalt (>80%). The purified nanotubes were further analyzed by TGA and Raman spectroscopy.
Sensorless control of induction motor with adaptive speed-flux observer

A novel sensorless controller for induction motor is presented. Indirect field oriented control approach and Lyapunov-adaptive design are exploited for the derivation of the controller and the speed-flux observer constituting the proposed solution. No direct integration of the neutrally stable stator flux dynamics is adopted. Persistency of excitation conditions with clear practical interpretation is derived to guarantee local exponential stability with a defined region of attraction for the proposed approach. Simulation results are provided.
An Inexact Newton-Based Approach to Microwave Imaging Within the Contrast Source Formulation

In this paper an approach to microwave imaging based on an inexact-Newton method within the contrast source formulation of the inverse scattering problem is considered. In this framework, the iteratively linearized equations of the inverse problem are solved by means of the regularizing truncated Landweber algorithm. This approach allows an effective and robust tool to inspect dielectric objects, as it is shown by the reported numerical results. Moreover, thanks to the structure of the involved integral equations within the contrast source formulation, computer memory saving can be obtained with respect to the electric field integral equation framework. Finally, the proposed method is validated against experimental data, kindly provided by the Institute Fresnel, Marseille, France.
Pressure dependence of optical transitions in semiconducting single‐walled carbon nanotubes

The effects of applied hydrostatic pressure on the optical transitions in semiconducting single‐walled carbon nanotubes with different diameters and chiralities have been studied using optical absorption and photoluminescence spectroscopy. The excitonic transitions associated with the band‐gap (the first van Hove transition) energies in the carbon nanotubes are found to shift to lower energy at a rate depending on nanotube structure. The excitonic transitions between the first excited confinement states (the second van Hove transitions) are found to be much less sensitive to the applied hydrostatic pressure. All nanotubes show a dependence on their chirality in terms of pressure coefficient of the band‐gap energy, with the larger‐diameter nanotubes exhibiting a higher sensitivity of the band‐gap energy to hydrostatic pressure.

ToxR regulon of Vibrio cholerae and its expression in vibrios shed by cholera patients

Toxigenic Vibrio cholerae cause cholera, a severe diarrheal disease responsible for significant morbidity and mortality worldwide. Two determinants, cholera enterotoxin (CT) and toxin coregulated pilus (TCP) are critical factors responsible for this organism's virulence. The genes for these virulence determinants belong to a network of genes (the ToxR regulon) whose expression is modulated by transcriptional regulators encoded by the toxRS, tcpPH, and toxT genes. To define the ToxR regulon more fully, mutants defective in these regulatory genes were transcriptionally profiled by using V. cholerae genomic microarrays. This study identified 13 genes that were transcriptionally repressed by the toxT mutation (all involved in CT and TCP biogenesis), and 27 and 60 genes that were transcriptionally repressed by the tcpPH and toxRS mutations, respectively. During the course of this analysis, we validated the use of a genomic DNA-based reference sample as a means to standardize and normalize data obtained in different microarray experiments. This method allowed the accurate transcriptional profiling of V. cholerae cells present in stools from cholera patients and the comparison of these profiles to those of wild-type and mutant strains of V. cholerae grown under optimal conditions for CT and TCP expression. Our results suggest that vibrios present in cholera stools carry transcripts for these two virulence determinants, albeit at relatively low levels compared with optimal in vitro conditions. The transcriptional profile of vibrios present in cholera stools also suggests that the bacteria experienced conditions of anaerobiosis, iron limitation, and nutrient deprivation within the human gastrointestinal tract.
SUBJECTIVE BELIEFS AND MULTIPLE PRIORS WITHOUT TRANSITIVITY AND MONOTONICITY

I relax transitivity and monotonicity in the subjective expected utility and multiple priors models. My extensions accommodate various behavioral patterns, such as partition dependence, source dependence, comparative ignorance, and preference reversals. I model complete preferences over Anscombe–Aumann’s state-contingent acts. My main results characterize bi-partitional representations where any acts f and g are compared via probabilistic beliefs or sets of beliefs that depend on the partitions π and τ generated by f and g respectively. The beliefs p(π, τ) and sets of beliefs M(π, τ) are determined uniquely on any generated partition π. Monotonicity and transitivity are not assumed, but can be imposed separately and interpreted in terms of simple mathematical properties of the functions p and M . Various refinements and applications are discussed.
Tomographic Evaluation of the Position and Form of the Mental Foramen in a Brazilian Subpopulation

The present study evaluated the position and shape of the mental foramen through Computed Tomography study. A total of 191 examinations of adult male and female toothed patients with an age range of 20 to 60 years were analyzed. The images were obtained through the I-Cat® tomography equipment and later analyzed with the device program itself, on a computer with a Microsoft Windows operating system. The data were organized into frequency tables and a descriptive analysis using the chi-square test, significance level of 5%. There was no statistical difference between genders and sides regarding the position and shape of the mental foramen. The mental foramen observed in this study was more frequently located at apex level in the vertical position and between the premolars in the horizontal position. The oval shape was the most frequent. It is expected that this work has a contribution to the dental surgeon in the knowledge of the form and the correct positioning of the mental foramen making possible a favorable prognosis in his clinical interventions.
Anxiety , Depression and Tobacco Abstinence Ansiedad , depresión y deshabituación tabáquica

There is evidence of the relationship between mental illness and smoking and increased risk of depressive episodes after quitting smoking, even with specific treatments for abstinence. Objective: To assess the influence of a cessation program on the emotional state of patients by measuring levels of anxiety / depression and differences depending on the presence of psychiatric history. Method: A prospective observational study of patients taking part in a combined program (pharmacological and cognitive-behavioral) for giving up smoking. Anxiety (A) and depression (D) were measured using the HADS questionnaire at baseline, first and third month of abstinence. Results: Anxiety and depression showed significant and progressive improvement during treatment (A: baseline 9.2 ± 4.5, 5.9 ± 3.6 1 month, 3 months 4.5 ± 3.1, p <0 05 / D: baseline 5.5 ± 4.1; 1 month 3 ± 3; 3 months 2.3 ± 2.1, p <0.05), in psychiatry population (A: baseline 11.3 ± 4 , 5; 1 month 7.1 ± 3.7, 5.3 ± 3.5 3 months, p <0.05 / D: baseline 7.4 ± 4.8, 4.2 ± 3.6 one month; 3 months 3 ± 2.9, p <0.05), regardless of treatment. Abstinence rate: 58.5%, unaffected by baseline levels of anxiety and depression. No significant neuropsychiatric side effects were detected. Conclusions: Anxiety and depression levels evolved favourably during the program, achieving good results regardless of the presence of psychiatric pathology.
