The relationships between nurse care, attitude of patient and nurse with cancer patient satisfaction

This study investigates the relationships between nurse care, attitude of patient and nurse with cancer patient satisfaction using the quantitative methodology. In Libya, the challenge of medical facilities and treatment is a current issue. Thus, this study was conducted to investigate the patients’ satisfaction at National Cancer Institute Misurata, Libya. The participants were 217 cancer patients of National Institute of Oncology located in Misurata, Libya. The study scale was adopted and adapted from that used by previous researchers to measure nurse care, nurse attitude, patient attitude, hospital service quality and patient satisfaction on a 5-point Likert scale. The nurse care, nurse attitude and patient attitude are independent variables and cancer patient satisfaction is the dependent variable in this study. On the other hand, hospital service quality and patient characteristic are control variables. SPSS software was used to analyses the data collected. The analyses of this study included descriptive statistic, correlation analysis and multiple regression analysis. The study found that on the overall basis, there is a significant statistical relationship between nurse care and cancer patient satisfaction, and there is a significant statistical relationship between attitude and cancer patient satisfaction. The sub-hypotheses show that there are no a relationship between interpersonal skills of nurse care and efficiency of nurse care with cancer patient satisfaction which suggest there might be interactions between these variables. Result also shows that for the sub-hypotheses, only patient attitude and cancer patient satisfaction indicated significant relationship, while there is no significant relationship between nurse attitude and patient satisfaction. This also indicates of possible interactions between the variables. On an overall basis, it can be concluded that to increase in the satisfaction level cancer patient, the management do it by focusing on improving the level of nurse care, nurse attitude and patient attitude.
Clinical efficacy of aloe vera based products available in the market as skin moisturiser measured by tewl value and skin hydration level by using dermalab technology

This study was conducted to evaluate the efficacy of Aloe Vera as skin moisturizer as measured by Trans Epidermal Water Loss (TEWL) and hydration value. The Dermalab®Combo was used to determine the efficacy of skin cosmetic products. Fifteen subjects were divided into three groups where each group was tested with one type of moisturizer product available in the local market. The TEWL and Hydration level of the subjects were measured before they were treated with the products as the baseline reading and after 3 weeks applying the products twice daily on the left forearm. The TEWL and Hydration levels were increased after 3 weeks for both side but the percentage increment of TEWL on the test side was lower than control side. Meanwhile, the percentage increment of Hydration level was higher on the test side compare to the control side. From the results, it is clear that Aloe Vera is effective for skin care treatment. In conclusion, it can be used as ingredient to improve skin barrier function for different skin care products formulations.
Skill-Structure Shocks, the Share of the High-Tech Sector and Economic Growth Dynamics, FEP Working Paper 554 January

By means of an endogenous growth model of directed technical change with vertical and horizontal R&D, we study a transitional-dynamics mechanism that is consistent with the changes in the share of the high- versus the low-tech sectors found in recent European data. Under the hypothesis of a positive shock in the proportion of high-skilled labour, the technological-knowledge bias channel leads to nonbalanced sectoral growth with a noticeable shift of resources across sectors. A simple calibration exercise suggests that, under prevailing market-scale effects, the model is able to account for up to 50 to 100 percent of the increase in the share of the high-tech sector observed in the data from 1995 to 2007. However, the model predicts that the dynamics of the share of the high-tech sector has no significant impact on the economic growth rate.
Renal Fractional Excretion of Sodium in Relation to Arterial Blood Gas and Spirometric Parameters in Chronic Obstructive Pulmonary Disease

Introduction: Arterial gas derangement could change urinary sodium excretion in Chronic Obstructive Pulmonary Disease (COPD) patients.There are very few and conflicting data in regards to the measurement of fractional excretion of sodium in COPD patients. The main aim of this study was to assess the relationship between renal fractional excretion of sodium(FeNa) with arterial blood gas and spirometric parameters in COPD. Materials and Methods: This study was a cross-sectional study performed on 40 consecutive stable COPD outpatients in 2 main general hospitals (Emam Reza, Ghaem) in Mashhad/Iran between 2011 and 2012. We investigated the relationship of renal FeNa with arterial blood gas parameters including HCO3, PH, PaCO2 and PaO2, and spirometric parameters. Analysis was done by SPSS v16 with a statistically meaningful p value of less than 0.05. Results: Mean age was 65.97±10.77 SD years and female to male ratio was 0.26. A renal FeNa of less than 1% was presented in 27% patients. There was a significant, positive relationship between renal FeNa and PaO2 (P=0.005, r=0.456). The correlations between PaCO2, HCO3, PH and spirometric parameters were not seen (P>0.05), but there was a significant relationship between Urine Na and PaO2. Outstanding, it seems likely that kidneys of COPD patients are responsible for sodium retaining state particularly in the presence of hypoxemia. Conclusion: This study indicates that in COPD patients, PaO2 but not PaCO2 is related to renal FeNa which shows the probable role of hypoxemia on sodium output in COPD patients. However, some caution is needed for interpretation of the probable role of hypercapnia on sodium retention in COPD.
Exploring a Behavioural Therapy for Insomnia in Shift Workers

About 30% of Canadian workers are on shift work schedules, and 8% to 32% of them suffer from Shift Work Disorder (SWD). Only a few behavioural treatments exist to treat this population. This study explores the efficacy and feasibility of sleep restriction therapy for insomnia in a group of night shift workers. Six participants (3 women) meeting SWD criteria were recruited. Mean age was 45.7 years old (SD=8.2). A multiple baseline design was used. After baseline, each participant received six to eight weekly treatment sessions. They completed several selfreported questionnaires and a daily sleep diary throughout the study. For each sleep period, sleep variables were calculated from the sleep diary. Two participants had a high treatment response and all others participants had a moderate response. Moreover, all participants presented at least two significant clinical improvements. Five participants presented a decreased in both sleepiness scores. The study suggests that sleep restriction therapy is effective, feasible, and reliable. Sleep restriction therapy for insomnia could improve sleep and diminish sleepiness in shift workers suffering from SWD. The present study opens new possibilities of treatment for shift workers that deserve greater attention in the future.
Modified Decision Based Coupled Window Median Filter

In this research work we have proposed a median filter capable enough to recover the original image to great extent, corrupted by high density Salt and Pepper Noise (SPN). It is named so as it appears as white and black dots in an image. The pixels of an image corrupted by SPN attains either maximum or minimum value i.e. ‘255’ or ‘0’. For the center processing pixel, if out of neighbor pixels, 3/4 th or more pixels are noise free then it confiscate the damaged pixels and then analyze the median otherwise the window is expanded up to a level and if in the last window selected no pixel is found noise free then processing pixel is replaced by the mean of each and every one of the elements in the chosen window. This is how image is filtered.
GREEN'S TENSOR FOR AN ELASTIC CIRCLE AND ITS APPLICATION IN MICROMECHANICS OF DEFECTS IN SOLIDS

The Green's tensor for the rst (displacement given) boundary value problem of elasticity for a circular domain is computed under a closed form expres- sion. The method of solution uses the \incompressible inuence element" for which the Green's tensor is given by representation using Green's function for Poisson's equation. Using such a representation, is shown that the main problem is to nd the dilatation along the boundary induced by the displacements Green's function. The volume dilatation is than obtained by solving an integral equation along the circu- lar boundary. Explicit expressions are obtained for the Green's displacements tensor and for the traction along the circular boundary, allowing expressing the solution for any kind of \displacement" boundary condition and body forces. On the basis of the constructed Green's tensor is given the integral formula which presents a gener- alization of the well known Poisson's integral formula from the theory of harmonic potentials onto the theory of elasticity. An example of application of Green's tensor in micromechanics of defects in solids as radial Volterra's slip dislocation in an elastic circle is presented. These results were obtained in explicit form and for the rst time. Applied here the \incompressible inuence element method" (IIEM) can be used to derive the Green's tensor for a wide classis of dierent boundary value problems for canonical domains of many systems of coordinates. So, IIEM will increase consider- able the possibilities to solve new complicate boundary value problems in bounded and \unbounded" solids, acted by dierent inner actions: body forces, temperature dislocations, Volterra's dislocations, eigenstrains, inclusions etc and any boundary displacements.
Stroke-Based Surface Reconstruction

In this paper, we present a surface reconstruction via 2D strokes and a vector field on the strokes based on a two-step method. In the first step, from sparse strokes drawn by artists and a given vector field on the strokes, we propose a nonlinear vector interpolation combining total variation (TV) and H 1 regularization with a curl-free con- straint for obtaining a dense vector field. In the second step, a height map is obtained by integrating the dense vector field in the first step. Jump discontinuities in surface and discontinuities of surface gradients can be well reconstructed without any surface distortion. We also provide a fast and efficient algorithm for solving the proposed func- tionals. Since vectors on the strokes are interpreted as a projection of surface gradients onto the plane, different types of strokes are easily devised to generate geometrically crucial structures such as ridge, valley, jump, bump, and dip on the surface. The stroke types help users to create a surface which they intuitively imagine from 2D strokes. We compare our results with conventional methods via many examples.

Analysis of Plant Microfossils in Archaeological Deposits from Two Remote Archipelagos: The Marshall Islands, Eastern Micronesia, and the Pitcairn Group, Southeast Polynesia1

ABSTRACT Pollen and starch residue analyses were conducted on 24 sediment samples from archaeological sites on Maloelap and Ebon Atolls in the Marshall Islands, eastern Micronesia, and Henderson and Pitcairn Islands in the Pitcairn Group, Southeast Polynesia. The sampled islands, two of which are “mystery islands” (Henderson and Pitcairn), previously occupied and abandoned before European contact, comprise three types of Pacific islands: low coral atolls, raised atolls, and volcanic islands. Pollen, starch grains, calcium oxylate crystals, and xylem cells of introduced non-Colocasia Araceae (aroids) were identified in the Marshalls and Henderson (ca. 1,900 yr B.P. and 1,200 yr B.P. at the earliest, respectively). The data provide direct evidence of prehistoric horticulture in those islands and initial fossil pollen sequences from Pitcairn Island. Combined with previous studies, the data also indicate a horticultural system on Henderson comprising both field and tree crops, with seven different cultigens, including at least two species of the Araceae. Starch grains and xylem cells of Ipomoea sp. , possibly introduced I. batatas, were identified in Pitcairn Island deposits dated to the last few centuries before European contact in 1790.
Battery inductive charging for electrical mobility applications

This report is a master thesis at the Department of Electrical Engineering at the Norwegian University of Science and Technology (NTNU). The purpose of the thesis was to find a control system used for regulating a system for inductive charging of electric ferries. Systems for inductive power transfer can be utilized in wireless charging of electric mobility applications. Wireless charging of electric mobility applications is especially advantageous for methods of public transportation that make short, but frequent stops, as buses and ferries. In this thesis, a system for inductive charging of electric ferries will be examined, with system design and specifications provided by SINTEF. The system is described and simplified in order to derive a transfer function that is simplified using dominant pole approximation. The resulting simplification is a second order transfer function of the form H(s) = a0 s+b1s+b0 with the terms a0, b1 and b0 varying according to the distance between the sending and receiving coils. Two scenarios for distance between the coils is looked into: A maximum distance, leading to a low coupling coefficient k for the system, and a minimum distance, leading to a high coupling coefficient for the system. For these cases of coupling two methods for controller design are looked into: Haalman’s loop shaping technique and experimental tuning by tuning maps. Based on these methods two controllers with constant gains are designed. The two methods lead to two controllers: One integral-only controller and one PID-controller in series with a filter. The systems’ responses with the two controllers is evaluated and compared, and it is concluded that the integral-only controller is the best choice for controlling the system.
Synthetic seismograms for a synthetic Earth: long-period P- and S-wave traveltime variations can be explained by temperature alone

SUMMARY Current interpretations of seismic observations typically argue for significant chemical heterogeneity being present in the two large low shear velocity provinces under Africa and the Pacific. Recently, however, it has been suggested that large lateral temperature variations in the lowermost mantle resulting from a strong thermal gradient across D″ may provide an alternative explanation. In case of a high heat flux from the core into the mantle, the magnitude of shear wave velocity variations in tomographic models can be reconciled with isochemical whole mantle flow and a pyrolite composition. So far, the hypothesis of strong core heating has been tested in a consistent manner only against tomographic S-wave velocity models, but not against P-wave velocity models. Here, we explore a new approach to assess geodynamic models and test the assumption of isochemical whole mantle flow with strong core heating directly against the statistics of observed traveltime variations of both P and S waves. Using a spectral element method, we simulate 3-D global wave propagation for periods down to 10 s in synthetic 3-D elastic structures derived from a geodynamic model. Seismic heterogeneity is predicted by converting the temperature field of a high-resolution mantle circulation model (MCM) into seismic velocities using thermodynamic models of mantle mineralogy. Being based on forward modelling only, this approach avoids the problems of limited resolution and non-uniqueness inherent in tomographic inversions while taking all possible finite-frequency effects into account. Capturing the correct physics of wave propagation allows for a consistent test of the assumption of high core heat flow against seismic data. The statistics of long-period body wave traveltime observations show a markedly different behaviour for P and S waves: the standard deviation of P-wave delay times stays almost constant with turning depth, whereas that of the S-wave delay times increases strongly throughout the mantle. Surprisingly, synthetic traveltime variations computed for the isochemical MCM reproduce these different trends. This is not expected from a ray-theoretical point of view and highlights the importance of finite-frequency effects. Most importantly, the large lateral temperature variations in the lower mantle related to strong core heating are able to explain most of the standard deviation of observed P- and S-wave delay times. This is a strong indication that seismic heterogeneity in the lower mantle is likely dominated by thermal variations on the length scales relevant for long-period body waves.
The ups and downs of ecosystem engineering by burrow-nesting seabirds on Triangle Island, British Columbia

RODWAY, M.S., WILSON, L.K. , LEMON, M.J.F. & MILLIKIN, R.L. 2017. The ups and downs of ecosystem engineering by burrownesting seabirds on Triangle Island, British Columbia. Marine Ornithology 45: 47–55. Some plant communities develop as a result of chemical and physical perturbations by burrowing seabirds and are affected when those activities are reduced. Declines in burrow density and population size of Cassin’s Auklets Ptychoramphus aleuticus at their largest breeding colony on Triangle Island, British Columbia, from 1989 to 2009, have been associated with decreases in tufted hairgrass Deschampsia cespitosa and increases in salmonberry Rubus spectabilis cover. These habitat changes may inhibit population recovery because Cassin’s Auklets prefer tufted hairgrass and tend to avoid tall salmonberry for nesting. Surveys conducted in 2014 suggested a reversal in the population trend and provided an opportunity to compare vegetation changes during periods of increasing and decreasing burrow density. We hypothesized that decreased burrowing by seabirds allows salmonberry to invade and outcompete grass as the dominant cover and that increased burrowing reverses those trends. We related changes in vegetation composition to trends in burrow numbers within permanent plots established to monitor Cassin’s and Rhinoceros Cerorhinca monocerata auklets on Triangle Island over a 25-year period. Trends in salmonberry cover and burrow numbers were negatively related. Decreases in salmonberry cover were directly correlated to increases in burrow numbers within plots, but, as found previously, increases in salmonberry cover were not directly correlated with decreasing numbers of burrows. There was no corresponding increase in grass cover with increasing burrow numbers. Vegetation damage and reduction due to seabird activities is probably more immediately apparent than establishment, spread or recovery of vegetation following seabird impacts. Our results confirm that biopedturbation by burrow-nesting seabirds negatively affects and reduces percent cover of woody shrubs, but only when burrow densities are increasing or high. At lower or declining burrow densities, seabird activities are inadequate to halt what may be the natural succession to mainly salmonberry cover on this non-forested island.
Genetics of Allopatric Populations of the Montane Vole (Microtus montanus) and Mogollon Vole (Microtus mogollonensis) in the American Southwest

ABSTRACT. Variation at 21 allozyme loci and 10 restriction enzymes within the mitochondrial DNA control region was assessed among 3 allopatric populations of montane vole (Microtus montanus) in the American Southwest. Among populations of M. montanus, the population from the White Mountains, Arizona, was most genetically divergent. Genetic and biogeographic evidence supported recognition of the White Mountains population as a distinct subspecies, M. m. arizonensis. Results also supported recognition of the Mogollon vole (Microtus mogollonensis) as distinct from the Mexican vole (Microtus mexicanus).
On-the-job Training and On-the-job Search: Wage-Training Contracts in a Frictional Labor Market∗

This paper analyzes the coexistence of on-the-job training and on-the-job search in a frictional labor market in which both skilled and unskilled workers engage in on-the-job search behavior and firms post skill-dependent wage-training contracts to preemptively back-load compensation and extract more surplus in earlier periods. The paper demonstrates that because back-loaded compensation after training effectively enlarges the expected duration, and joint value, of the match as if it were job-specific training, general training is over-intensified overall. Comparative static analysis predicts aggregate training intensity to be reinforced, but net output to improve toward the Beckerian outcome, as search friction is mitigated.
Neuropsychological assessment of the decision making process in children and adolescents: an integrative review of the literature Avaliação neuropsicológica do processo de tomada de decisões em crianças e adolescentes: uma revisão integrativa da literatura

Objective: Nowadays there has been growing interest in the “hot” aspects of the executive functions related to the orbitofrontal cortex (OFC), in particular in the affective decision-making process in children and adolescents. We reviewed the available literature about the evaluation of decision making in children and adolescents. Method: We searched for papers published from 2000 to 2009 that studied children and/or adolescents until the age of 16 in the Lilacs and PubMed index. The papers were analyzed according to the paradigms used in the studies, the conclusions about the development of the decision-making process, and the ability to distinguish between the clinical population and the controls. Results: Thirty-six papers were selected. Compared to the amount of studies of adults, there are still few studies focusing on children and adolescents. Several versions derived from the IGT were developed in order to study decision-making processes in children and adolescents. Discussion: The IGT is the most used instrument. In preschoolers, simplified versions have been used with greater frequency. The different paradigms are useful in differentiating between normal and psychiatric disorder patients. The results are positively and significantly related to the frequency of impulsive behaviors in nonclinical populations.
Vision based navigation using Kalman approach for SLAM

The aim of this paper is to present a vision based algorithm for simultaneous localisation and map building (SLAM) for indoor environment. The approach is based on the well known predictor-corrector structure of the Extended Kalman Filter and makes use of vision data in the correction phase. To this aim a low cost vision system is presented, with a fast image processing procedure for features extraction, based on the recognition of artificial sources of light in an officelike environment. Experimental tests, carried out on a robotic wheelchair equipped with the vision system, show the satisfactory performance of the mobile platform under realistic operating conditions.
