Authors: Steinke Elaine E
Published: May 2014

ABSTRACT

Individuals experiencing a chronic illness have many needs and concerns. One area frequently overlooked is that of intimacy. Those experiencing cardiovascular illnesses have concerns about the strain of sexual activity on their heart. Individuals with lung diseases may perceive that sexual activity is no longer possible because of breathing difficulties. Accurate information and strategies for self-management are needed to address the intimacy needs and concerns of these individuals. The purpose of this article is to identify intimacy needs and strategies for sexual counseling for individuals with cardiovascular illnesses such as myocardial infarction, heart failure, implantable defibrillators, hypertension, and for chronic lung problems.
GRANDMOTHER CAREGIVER REACTIONS TO Caring for High-Risk Grandchildren "I could write a book!"
Authors: Dowdell Elizabeth Burgess
Published: May 2014

designed and conducted to examine the relationship between caregiver burden and caregiver physical health for grandmothers raising their high-risk grandchildren. The sample consisted of 104 grandmothers. The findings indicated that caregiver physical health correlated strongly with level of burden and financial status. Further analysis suggests physical health variables had an observable impact on caregiver burden.

Because this study indicates, from descriptive and correlational statistics, that the well-being of the grandmother and grandchild are both linked to the grandmother's physical health, there are numerous nursing interventions that may support a positive outcome for both. The provision of emotional and psychosocial support, coupled with health education and periodic health evaluations, are known to improve a grandmother's perception of her own health. Nurses can use the measures of caregiver burden to develop care plans targeting the health issues most likely to improve a grandmother's functional ability to remain the primary caregiver for a high-risk grandchild.

Perceived Health and Life Satisfaction Among Older Adults: The Effects of Worry and Personal Variables
Authors: Fakouri Carolyn , Lyon Brenda
Published: May 2014

ABSTRACT

The purpose of this study was to describe how worry affects two desired outcomes of nursing care for older adults - perceived health and life satisfaction. A convenience sample of 100 individuals (ages 65 to 97) living in the community responded to the questionnaire. Despite several chronic diseases, 89% of the participants perceived themselves as "well." Descriptive statistics revealed relatively high life satisfaction. Data from the Perceived Health Scale indicated the participants were functioning near their normal capacity, and with few negative emotions and physical sensations. Worry was also minimal. Nevertheless, using multiple regression, worry contributed to lower life satisfaction, negative emotions, physical discomforts, and decreased functional ability. Because the reported worries were primarily related to health and functioning, assessment of worry is significant when planning nursing care for older adults.

Published: May 2014

ABSTRACT

The purpose of this study was identify how cognitive appraisal and types of coping affect the health status of men with prostate cancer. Lazarus and Folkman's model of stress and coping guided this correlational, cross-sectional study. The convenience sample was composed of 131 men with prostate cancer who completed the Cognitive Appraisal of Health Scale, the Ways of Coping Checklist, and the Short-Form Health Survey using mailed questionnaires. Participants who appraised more harm or loss experienced worse physical and mental health. When participants perceived their diagnosis as posing more harm or loss or a greater threat, they were more likely to use emotion-focused coping. When the diagnosis was perceived as a challenge, men were more likely to use more problem-focused coping. The findings of this study enable health care providers to be more attentive to the psychosocial needs of prostate cancer patients.

Na sombra de Herculano: Miguel Ângelo Pereira e os desafios de compor ópera no Portugal dos anos 1860-70
Authors: Cymbron Luísa
Published: May 2014

En febrero de 1870 se estrenó en el Teatro de S. Carlos de Lisboa una ópera cuyo libreto había sido extraído de Eurico, de Alexandre Herculano. El autor de la música, Miguel Ângelo Pereira (1843-1901), era un joven pianista y compositor oriundo del norte de Portugal que había pasado parte de su infancia y adolescencia en Brasil. A pesar de que fue mal recibida por el público y por la crítica, la ópera fue repuesta en 1874, en Oporto, y en 1878, en Río de Janeiro. Desde el principio Eurico fue retratada como una obra diferente al repertorio corriente, asociada a veces con el universo de la música instrumental germánica. A través de las pocas fuentes que han sobrevivido y de la prensa contemporánea, este artículo procura mostrar cómo ella se encuadra en los proyectos de creación de una ópera nacional portuguesa, por parte de un grupo de emigrantes en Río de Janeiro; cómo, en términos dramatúrgicos y musicales, se aproxima a la estética de la grand opéra; y cómo el perfil psicológico de Miguel Ângelo –que se imaginaba y es descrito por sus contemporáneos, como un héroe en busca de un ideal– aliado con la emergencia de un novo canon musical, fundado sobre las obras de compositores alemanes, condujo a que, ya después de la muerte de su autor, en 1901, ella fuese consagrada como la primera tentativa de que un compositor portugués se aproximase a los modelos wagnerianos.
Sintomas de “regionalismo crítico”: sobre o “decorativismo” na pintura de Amadeo de Souza Cardoso
Authors: Cunha Leal Joana
Published: May 2014

Se analiza cómo la historiografía portuguesa dimensionó la relación que la pintura de Amadeo de Souza Cardoso (1887-1918) establece entre las indagaciones internacionales del modernismo y su regional “portugalidad”. Somos conducidos así a la idea de que el origen portugués introduce en la obra de Amadeo, por putativa insuficiencia cultural y estética, un ingenuo provincianismo desprovisto de instancia crítica. Ese provincianismo lo haría apropiarse decorativamente de los célebres discos simultáneos de Robert Delaunay. Este artículo pretende discutir esa tesis, procurando demostrar que, lejos de la distorsión que se le atribuye, la apropiación “decorativa” que Amadeo hace de ese elemento se inscribe en un plano de resistencia cercano a la idea de “regionalismo crítico”. Sobreviene, por fin, la hipótesis, desarrollada a partir del análisis de una tele de 1917, de que la invisibilidad de tales síntomas de resistencia sea sobre todo deudora de una perspectiva que asocia el modernismo a la superación de la representación en las artes plásticas.
A Primeira República Portuguesa (1910-1926): partidos e sistema político
Authors: Baiôa Manuel
Published: May 2014

El Partido Republicano Portugués se convirtió en el partido dominante del sistema político de la Primera República Portuguesa (1910-1926) debido a causas históricas, organizacionales, clientelistas, violentas y constitucionales. La oposición sentía que difícilmente conseguiría la alternancia política a través de elecciones, y por lo tanto, recurre a prácticas violentas e inconstitucionales para llegar al gobierno. Los partidos políticos portugueses se modernizaron en este período, pero no se convirtieron en partidos de masas. En las principales ciudades actuaban como partidos de cuadros y en las zonas rurales como partidos de notables. Durante la Primera República no se dieron pasos consistentes para democratizar el sistema político. Portugal se mantuvo ancorado a la tradición liberal y elitista del siglo XIX, aunque en una versión republicana.

Numerical Simulation of Heat Conduction for Error Analysis on Heat Flux Sensor Embedded in Flat Steel Plate
Authors: Tian Chun Lai , Zhou Shan , Han Li Yong
Published: May 2014

A numerical simulation model of heat flux sensors embedded in a flat plate is established. Each sensor has four thermal couples and is inserted into the specified hole. The problem is defined as a steady heat conduction problem with specified boundary conditions and solved by the finite element method. The results of the simulation case demonstrate that the maximum heat flux appears near the sensor shell. The average heat flux of the plate is much smaller than the maximum. Due to exiting of the contact heat resistance, the temperature of the sensor is much lower than that of the plate at horizontal surface. The maximum temperature difference appears on the bottom shell of the sensor. The maximum temperature difference between the simulation results and the experimental data at test points is 1.5 K. The model is verified and could be accepted for the further errors analysis.

Standby-Energy-Saving Socket
Authors: Wu Yu Chi , Chen Meng Jen , Liao Hsien Min , Yang Bo Huei , Lin Jing Yuan
Published: May 2014

Most home electric appliances have standby energy waste when they are at idle mode. This standby energy is about 3% to 11% of total household electricity consumption. For several millions of households in Taiwan, this standby energy would cause billion dollars of waste per year. Therefore, in this paper we propose a standby-energy-saving socket using a microcontroller unit (MCU) to reduce the standby-energy waste. The user can start up this standby-energy-saving socket to supply power to appliances through the appliances infrared remote control or the button on the socket. When the appliances enter into the standby mode, the current sensor in the socket automatically detects it and the MCU turns off the power through a relay to reduce the standby power to zero. Based on the test, the MCU in the proposed standby-energy-saving socket only consumes about 3 mW when the socket is at sleep mode, 6 mW at working mode. The cost of this proposed socket is $9. The standby-energy saving tested on a PC is reduced by 99.93%.

Authors: Li Na , Shen Hong Hai , Liu Shi Quan
Published: May 2014

Sintered glass-ceramics have been successfully prepared using glass particles derived from a waste water flocculate. Influence of heat treatment conditions (sintering temperature and soaking time, heating rate) and size of the glass particles on the microstructure and density, hardness of the obtained glass-ceramics has been studied. The results show that the prepared glass-ceramics have gehlenite and anorthite as main crystalline phases. SEM analysis indicates that the size and morphology of the crystallites vary with the preparation conditions. A dense glass-ceramic with a high hardness can be obtained by sintering glass powder sized smaller than 0.075mm with a relatively slow ramping rate (3°C/min) to a temperature higher than the crystallization peak temperature of the parent glass for a short period of 30min to 1h.

Authors: Chen Lei , Yu Zhi Xin , Cui Wei Ping , Qin Li Juan
Published: May 2014

Development of normal stress in the direction perpendicular to the asphalt mixture is an important feature of the nonlinear viscoelastic behavior of asphalt binders. In this paper, this phenomenon was studied with the help of stress-relaxation experiments in torsion.  Results indicate that stress relaxation test by controlling strain could be used to evaluate the stress relaxation ability of asphalt mixture. With the aging degree of asphalt mixtures increased, the low temperature cracking resistance got worse; the higher the temperature is, the faster the stress relaxed; the smaller the initial strain, the worse the stress relaxation ability also. The viscoelasticity of asphalt mixture could be simulated by exponential model fractional and the experiments well supported the modeling results.

Published: May 2014

A series of poly (butylenes succinate) with low Glycerol (GL) fraction ranging from 0 to 6‰ were synthesized by two step melting condensation. By this method, some three-dimentional branch or crosslink structure was introduced to the linear aliphatic chain of PBS. The sequence distribution, GL fraction, crystal structure and degradability were investigated. The degrability of PBS enhanced when GL was led into polymer chain as the crystalline (χc) decreased with GL increasing. And the degradation first happened in amorphous region and then crystal region.

Published: May 2014

The sequential microhydration of sodium glycinate is investigated at the MP2/6-311++G(d,p) level. Our results clearly indicate that the microhydration process is driven by the charge site of sodium cation and a bridge site is losing its dominant position. Eventually, a comparison of theoretical and experimental Raman spectra provides the evidence of the predicted structural information.

Authors: Du Deng Yun , Song Xue Wei , Sun Xiao Yan , Zhang Qian , Hu Hao
Published: May 2014

A finite element model with detailed anatomical structure of human cervical spine was established in this paper based on the CT scan data of the cervical vertebrae obtained from a 50th percentile Chinese male. The model was validated by the data from the head-neck drop test conducted by Nightingale et al in 1996. In the drop test simulation, the contact force between the head and impact surface, as well as head acceleration were chosen to gauge the accuracy of the model predictions against test results. The results show that the head - neck finite element model without muscle tissue has a consistent mechanics and dynamics with the body drop test. The model can be applied to the exploration of a more detailed neck injury model with muscle tissue and can also be directly applied to the study of injury mechanism of the cervical spine in the car crash accidents.

Published: May 2014

Based on the equivalent radius model and superposition potential, a productivity model for ultra-low permeability tight gas reservoirs was developed, which considered the influence of the threshold pressure gradient and the variable mass flow in fractures, and pressure loss inside the wellbore. With examples for capacity sensitive factors are analyzed. The results show that the threshold pressure gradient must be accounted to evaluate the productivity in ultra-low permeability tight gas reservoirs; after considering wellbore pressure loss; close toe fractures inflow velocity segment has been reduced; the larger matrix permeability, the greater the optimum fracture conductivity; When the number of fracture is more, the greater the impact on the capacity of the fracture angle. The research results provide a scientific basis for the design of multi-fractured horizontal wells in the ultra-low permeability tight gas reservoirs.

Published: May 2014

Myocardial strain is a dimensionless quantity and is produced by application of stress. It represents the fractional or percentage change from the original or unstressed dimension and includes both lengthening, or expansion and shortening, or compression. In this paper, we proposed an algorithm to identify the heart dysfunctions through the comparison of the normalized strain and strain rate curves based on cubic B-spline interpolation, after non linear deformation of strain curves and vertical rescaling, abnormal curves can be identified visually based on the curves. Numerical verification of the proposed algorithm illustrated the effectiveness of it.

Authors: Yang Jie , Yang Yan Jun , Zeng Yun
Published: May 2014

In this paper, a Pipeline ADC applied in medical image sensor was designed, and the analog / digital operating voltage was 3.3/1.2V respectively, the area was 0.326mm2. Because the gain bootstrap op-amp structure has been improved and the dynamic comparator was used, which reduced the overall power consumption of the ADC. The simulation results showed that in the normal working mode, the total current of ADC was about 6.5 mA; when the sampling rate was lower than 17.5 MHz, the working mode was switched to the LP (low power) mode, and the total current was 4.5 mA. In addition, the tapeout test results showed that the other performance parameters of ADC were good, the sampling rate was 35 M/s, and SNR was 58dB.

Published: May 2014

The purpose of this study was to investigate the biocompatibility and degradation behavior of theophylline/chitosan microspheres, which has the potential application in pulmonary delivery system. Hemolysis test was carried out to estimate its blood toxicity. In vitro enzymatic hydrolysis was performed in 0.2 mg/ml lysozyme solution, while in vitro hydrolysis degradation was in 0.2 mol/L PBS solution (pH 7.4). The results of hemolysis test showed that the hemolysis rate was 4.771%, which showed that theophylline/chitosan microspheres had no hemolysis. The degradation rate of enzymatic hydrolysis and PBS hydrolysis was 62.66±2.1% and 37.79±1.2%, which indicates that degradation in lysozyme solution is faster than that in PBS solution. The morphology of microspheres with lysozyme and PBS solution developed into rough surfaces and became irregularly shaped. Accordingly, theophylline/chitosan microspheres possess preferable biocompability and degradation, which have promising potential for use as safe carrier in pulmonary drug delivery systems.
