Objective: To investigate if caries in the pre-treatment early mixed dentition is associated with caries development in the permanent dentition during orthodontic treatment. Material and Methods: We included 41 consecutive patients (29 girls, 12 boys) with a pre-treatment documentation in the mixed (mean age 9.4 years) and a post treatment documentation in the permanent dentition (age 14.9 years) (two-phased treatment time 4.5 (±1.6) years). The DMFT/S indices were calculated. High-risk and low-risk groups were defined according to dmfs + DMFS score before treatment. Results: Initial dmft/s + DMFT/S (SD) was 5.15 (3.60) and 8.32 (6.64);final DMFT/S was 2.76 (2.84) and 3.01 (3.20). The missing (because of decay) second deciduous molars were most powerfully associated with caries increment during treatment, showing significant correlations to second premolars (r = 0.47, p = 0.003), while fillings on second deciduous molars seem to influence the prevalence of fillings on permanent molars (r = 0.44, p = 0.001). The increment at surface level was 2.01 (2.61) in the whole sample and 2.60 (3.81) in the high-risk group (4 boys, 6 girls). Compared to the low-risk group (10 girls), post-treatment caries experience was significantly higher in the high-risk group (p = 0.029). Boys were more at risk than girls (p = 0.005). Conclusions: Children with elevated caries experience in the early mixed dentition are exposed to higher caries risk during orthodontic treatment. Thus, in prevision of treatment, caries should already be assessed in the mixed dentition, so that an extended prophylaxis program can be initiated.

＜正＞1 INTRODUCTION In the recent decades there has been a great deal of interest for Coriolis mass flowmeters （CMF）. The market for CMF has grown dramatically in the late 80’s and the 90’s. Nowadays, CMF are widely accepted in many industrial fields and the performance of CMF has been improved steadily. One of the advantages of CMF is, that they are measuring directly the true mass flow. The high accuracy and rangeability of CMF is a further reason for its fast growth and acceptance in industry. The commercially available CMF show a broad variety of designs, such as single tube, dual tubes, bent tubes or straight tubes. Since CMF are available with different tube materials like stainless steel, Hastelloy, titanium, zirconium or tantalum, they can be used for all kinds of liquids or *** paper gives a state of the art review of CMF and focusses on recent innovations.2 STATE OF THE ART REVIEWMeasuring variables.

公元862年,逃犯鲍德温在绑架了国王最心爱的女儿后,逃到了布鲁日。国王只好把这片土地封给了他,而鲍德温也从此痛改前非,大力改善当地的治安,最终这座城市连北欧海盗也不敢轻易涉足……布鲁日素有"北方威尼斯"之称,这里运河交织,桥梁众多,城墙环绕,步道纵横,漫步在中世纪的石子小道上,会有一种时光倒流的感觉。圣血教堂的水晶瓶里,收藏着耶稣受难时流下的血,被信徒们奉为"圣血",据说每到某个特定的时刻,那些干涸的血迹就会转变成液态,和新鲜的血液并无二致……

本文提出了一种基于现场可编程门阵列(FPGA)的多电平空间矢量脉宽调制(SVPWM)的有效实现方案。所提方法的目的,是在不带来任何缺点的前提下减少必要的处理需求,并能够自动实现最小开关切换和直流侧电容电压最优控制的多电平开关序列。文中给出了用FPGA控制的两个30kW的三电平IGBT逆变器构成的五电平逆变器实验结果。由于简洁高效的硬件描述语言(VHDL),状态机编程使得整个实现过程非常迅速,在极高的开关频率下也可以采用成本低廉的单芯片来满足要求。
