Replantation of the Severed Upper Arm of a 9-Month-Old Infant

Abstract: A 9-month-old infant whose left arm was cut off completely by an electric saw at the lower one-third part of the upper arm. The patient had a pale complexion, and her vital signs showed“T:35.4 °C; P:147 times/min; R:28times/min; Bp:89/58 mmHg”. There were no abnormalities in cardiopulmonary and abdominal examinations (Fig. 6.1).

Experiment and simulation of microwave detection using IQ demodulation method for breast tumor screening

Abstract: Abstract Breast cancer has become the most diagnosed cancer in the world. Microwave detection the breast tumor is attractive due to its high dielectric property contrast between different tissues of tumor. In this paper, we proposed an In-phase-Quadrature (IQ) demodulation-based method to detect the breast tumor with microwave at a frequency of 1.3 GHz. The microwave detection system consists of two signal generators, 12 transmitting/receiving antennas, two talent switches, a phantom and an IQ-Mixer. The amplitude information at the receiving antennas can be obtained by analyzing the difference frequency signals generated with two microwave signal generators. We also use the finite-difference time-domain (FDTD) method for simulation verification, which can simulate the propagation of the electromagnetic wave. Through experiments and simulations of microwave hardware system and FDTD method, it can be proved that the results are consistent. The experimental and simulation results show that when the tumor phantom diameter decreases or its depth from the receiving antenna increases, whether there is a tumor phantom can be clearly distinguished. Moreover, we also explore the effects of different tumor phantom locations on the receiving antennas. The results show that it is feasible to detect the breast tumor with the IQ demodulation method based on microwave.

Measuring Carbon Emissions for Basic Necessities

Abstract: Sen (Commodities and Capabilities. North-Holland, Amsterdam, p. 130, 1985) criticizes the neoclassic economic growth model and believes that the fundamental objective of development is to expand people’s scope of choices and achieve people’s comprehensive development.

Wearing high heels with an appropriate height is protective for pelvic floor function.

Abstract: Background Wearing high-heeled shoes is a common phenomenon among women. However, the association between wearing high heels and pelvic floor function is largely unknown. Our aim was to evaluate the effects of wearing different height shoes on pelvic floor function and to analyze the influencing factors. Methods This was a population-based, cross-sectional study performed in general hospitals with a pelvic floor subspecialty in some cities of China. All participants completed a Urogenital Distress Inventory (UDI-6) questionnaire that consisted of demographic data, information about wearing shoes, and information about pelvic floor function (UDI-6). One-way ANOVA was carried out to compare the differences among 4 groups according to the heel height ( 7 cm groups). Multivariate logistic regression was performed to identify the factors influencing the effect of wearing 3-5 cm high-heeled shoes on pelvic floor function. Results In total, 1,263 participants finished the questionnaire and full data were collected. The 4 groups were comparable for clinical data, and participants who wore 3-5 cm high-heeled shoes had the lowest UDI-6 scores. Multivariate analysis revealed that the number of hours (≥8 h) wearing high heels per day and the thickness diameter (≥3 cm) of the heel were important factors affecting the protective effect of wearing 3-5 cm high-heeled shoes on pelvic floor function. Conclusions Wearing heeled shoes with a 3-5 cm heel height and ≥3 cm thickness for a long period of time is good for the pelvic floor function of women.

Prospects of Carbon Emissions as Bads for Trading

Abstract: AbstractChina's policy of building a national carbon emission trading system has attracted wide attention around the world. Is emission trading an effective instrument for boosting low carbon development. Does it have a promising market prospect? How make carbon markets exert positive and effective functions?
