One of the ethical challenges in nursing profession is moral distress. Nurses frequently expose to this phenomenon which leads to different consequences such as being bored by delivering patient care that decline care quality and make it challenging to achieve health purposes. This study was conducted to investigate the association between the aspects of moral distress and care quality.Methods: In this descriptive–analytical study, 545 nurses of intensive and cardiac care units and dialysis and psychiatric wards were recruited by census sampling. Three questionnaires, Sociodemographics, Moral Distress Scale, and Quality Patient Care Scale, were distributed among the participants and collected within 9 months. Data analysis was conducted by descriptive statistics, analysis of variance, and the least significant difference in SPSS 13.Results: Investigating moral distress domains(ignoring patient, decision-making power, and professional competence) and care quality domains(psychosocial, physical, and communicational) demonstrated that in being exposed to moral distress, ignoring patient had no effect on psychosocial domain(P=0.056), but decision-making and professional competence of moral distress had positive effect on psychosocial, physical(bodily), and communication domains of care quality.Conclusions: Because moral distress domains are effective on patient care quality, it is recommended to enhance the knowledge of nurses, especially beginners, about moral distress, increase their strength alongside standardizing nursing services in decisionmaking domains, improve the professional competence, and pay attention to patients. 展开更多

Ultrasonic waves have a lot of use in the particle surface cleaning.As flotation is one of the methods associated with surface properties,this paper investigates the effect of these waves on performance,particle size,reagents,and feed ash content in coal flotation.To accomplish this goal,coal samples in three size fractions,including coarse(-800 to+400μm),medium(-400 to+100 μm)and fine(-100μm)with various feed ash content.The flotation experiments were evaluated by process indexes such as yield,combustible recovery,and selectivity index.The results indicated the increasing of yield.The increasing was significant in medium size.Furthermore,the results showed that in presence of ultrasonic waves,the collector and frother consumption decreased.And also,applying ultrasonic waves would result more combustible recovery and selectivity index.The ash selectivity index had the highest impact for high feed ash content. 展开更多

In this paper, Multiband-OFDM UWB system based on IEEE 802.15.3a standard is studied and simulated with spatial, time and frequency (STF)coding scheme. The using of STF coding method can guarantee both full symbol rate and full diversity advantages. The simulation results show that the STF code uses multi- path-rich and random-clustering characteristics of UWB channel environment on the performance of MB- OFDM system. 展开更多

In this paper,the influence of various field shapers and their shapes on the distribution of the magnetic flux densities and applied forces on the work-piece in the electromagnetic inward tube forming are studied numerically using the FEA software MAXWELL.First the model was verified with experimental results and thereafter four kinds of field shapers(conical,cylindrical,concave and convex)were considered.Effects of their geometries,such as air gap between field shaper and tube work-piece,height of the step in single and multiple stepped field shaper on magnetic flux densities and magnetic pressures were studied.The results of this research can be applied to design field shaper,tube compression technology,and improve the efficiency of the coil.It is seen that magnetic force decreases if height of step in convex field shaper increases but effective forming region enlarges.Decreasing air gap has also a positive influence on magnetic field increase.Though the object of this research is limited to field shaper for inward tube forming,the results can also be applied to the field shaper for tube bulging. 展开更多
