Previous research in Scotland used a merging approach to combine census boundary data for geographies specific to 1981, 1991 and 2001 to create Consistent Areas Through Time (CATTs) for the analysis of health and social data for small areas. In this paper, we adopt the same methodology to integrate the 2011 Scottish Output Areas to the CATTs. First, we overlaid the 2001 Output Areas upon the 2011 Output Areas to create SUPER OAs, which were then combined with SUPER EDs, which represented a consistent small area geography for 1981 and 1991. This resulted in 8,548 CATTs providing a consistent geography for the 1981, 1991, 2001 and 2011 Censuses in Scotland. We demonstrate the utility of the CATTs by exploring the correlations between deprivation, the proportion of the population who were permanently sick and those with degree qualifications, across the 4 censuses, a research angle impossible without consistent geographies. We have provided a resource that enables users to deepen their understanding of small area social changes in Scotland between the 1981 and 2011 Censuses. 相似文献

A pregelatinized starch (PGS) was derivatized with sodium chloroacetate (SCA) in alcoholic medium under alkaline condition to produce carboxymethyl pregelatinized starch (CMPGS) with various degrees of substitution (DS). Influence of the molar ratio of SCA to the glucopyranose units (SCA/GU), reaction time, temperature and the amount of sodium hydroxide on the degree of substitution (DS) and the reaction efficiency (RE) was studied. An optimal concentration of 30% of NaOH, for a reaction time of 1 h at 50 °C and molar ratio (SCA/GU) equal to 1.0, yielded an optimal DS of 0.55 and a RE of 55%. SEM micrographs revealed that the carboxymethylation assigned the structural arrangement of CMPGS and caused the granular disintegration. Wide angle diffraction X-ray (XRD) showed that the crystallinity of starch was obviously varied after carboxymethylation. New bands in FTIR spectra at 1417 and 1603 cm−1 indicated the presence of carboxymethyl groups. The solubility and viscosity of CMPGS increased with an increase in the degree of modification. In order to investigate the influence of DS on physical and drug release properties, CMPGS obtained with DS in the range of 0.12–0.55 was evaluated as tablet excipient for sustained drug release. Dissolution tests performed in phosphate buffer (pH 6.8), with Ibuprofen as drug model (25% loading) showed that CMPGS seems suitable to be used as sustained release excipient since the drug release was driven over a period up to 8 h. The in vitro release kinetics studies revealed that all formulations fit well with Korsmeyer-Peppas model and the mechanism of drug release is non-Fickian diffusion. 相似文献

Risedronate is a nitrogen-containing bisphosphonate for the treatment and prevention of postmenopausal osteoporosis. The current work aims to develop a novel green HPLC-UV method for the rapid analysis of risedronate sodium in bulk and tablet formulation. The analyzed samples were separated on Waters Atlantis dC18 (150 mm × 3.9 mm; 5 μm) column using a green mobile phase consisting of potassium phosphate buffer pH 2.9 and potassium edetate buffer pH 9.5 in a ratio of 1:2, the final pH was adjusted to 6.8 with phosphoric acid, the mobile phase was pumped at a rate of 1.0 mL/min, with column temperature set at 30 °C, eluted samples were detected at 263 nm and the chromatographic run time was 3.0 min. The method was found to be linear over the concentration range of 14–140 μg/mL with a correlation coefficient (r2) of 0.9994. Accuracy and precision were evaluated from three QC samples (LQC, MQC and HQC) together with the five calibrators where the percentage accuracy was found to be 101.84%. Processed quality control samples of risedronate sodium were tested for stability at different conditions, short term, long term and freeze- thaw stability. The current method was further extended to study the content uniformity of Actonel® tablets following United States Pharmacopoeia (USP) guidelines. The proposed method was fully validated as per ICH guidelines. 相似文献

BackgroundFrequent patient handling activities present numerous challenges to healthcare workers. A variety of products are available to assist with in-bed positioning but few comparative studies have been completed to ascertain turning effectiveness.MethodsThe purpose of this study was to compare two turning devices (air-powered positioning system with wedges versus ceiling lift with pillows) for in-bed repositioning and turning effectiveness. The study took place at a large community hospital in the Midwestern USA and used a prospective, four-group crossover study design to compare devices.ResultsThe two turning groups were not significantly different for any of the demographic variables. The use of an air-powered positioning system with wedges achieved a greater degree of turn and maintained that turn after an hour better than the lift device with pillows. There were no hospital acquired pressure injuries in either group.ConclusionThe devices used demonstrated significant differences in turn angle achieved and ability to maintain the turn at one hour. Future studies need to further delineate the ideal method for turning and compare devices to identify best practice and equipment. An effective turning method would integrate ease of use with the ability to achieve an optimal degree of turn in order to prevent hospital acquired pressure injuries while also decreasing caregiver injuries. 相似文献

IntroductionPractical training for medical students is provided during the final years of study and is determined by several conditioning factors, including the MIR training that students receive simultaneously. In general, practical training evaluation receives much less attention than the theoretical one; its quality is not evaluated, and the professors do not receive feedback. The objective of our study was to determine how students value practical training in pulmonology rated the experience after completing a three-week rotation, in order to apply the information gained toward a process of continual improvement.MethodsThe study included 2 anonymous surveys taken by medical students during the same academic year-one internal, prepared by the Department of Pneumology, itself, and another external one, prepared by the Evaluation Unit for Teaching Excellence at the University of Salamanca.ResultsOn the internal evaluation, student opinions of their practical training ran high (8.26) and the perceived usefulness was also high (8.23), on a scale of 0 to 10 and no differences were noted according to whether the survey was taken during their fourth, fifth, or sixth year of study. These results agree with those obtained in the external evaluation with a mean value of 4.56 on a scale of 0 to 5. Student preferences during their rotation in the department were for hospitalization and consultation units, with the technical areas being lesser valued.ConclusionsAchieving and maintaining a high quality of practical training is a goal that should be consistently evaluated so that professors may receive feedback (internal and external). Rotations in the Department of Pneumology provide an opportunity to improve the perception that medical students have regarding this specialty. It is imperative to reflect upon the contents of these rotations, seeking a balance between clinical areas and technical areas. 相似文献

OBJECTIVES: This study evaluated the effect of a warm or cold air-dry stream for solvent evaporation on the microtensile resin-dentin bond strength (muTBS), nanoleakage pattern (SEM), degree of conversion (DC) and solvent evaporation rates (SE) of an ethanol/water- (Adper Single Bond, [SB] 3MESPE) and an acetone-based (Prime & Bond 2.1, [PB] Dentsply), two-step etch-and-rinse adhesive system. MATERIALS AND METHODS: Adhesives were applied on demineralized dentin surfaces. For SE, a warm or cold air-dry stream (10 s) was applied prior to light-activation (10 s). Bonded sticks (0.8mm2) were tested in tension (0.5 mm/min). Two bonded sticks from each tooth were immersed in a 50% (w/v) solution of silver nitrate (24 h), photodeveloped (8 h) and analyzed by SEM. The DC and solvent evaporation rate of the adhesives were evaluated under FTIR and analytical balance, respectively. Data were analyzed by two-way ANOVA and Tukey test (alpha=0.05). RESULTS: Higher muTBS and lower nanoleakage were observed when the SE step was performed with warm air-dry stream. However, the DC of the adhesives was not altered by the use of a warm air-dry. CONCLUSIONS: The use of a warm air-dry stream seems to be a clinical tool to improve the bond strength and the quality of the hybrid layer (less nanoleakage infiltration), since it might reduce the number of pores within the adhesive layer. 相似文献
