嵌人式与独立存储器设计上的差异分析和研究

进入21世纪,随着集成电路的发展,SoC(System on Chip)片上系统应运而生。而作为SoC重要组成部分的嵌入式存储器,在SoC中所占的比重正逐步增加,并起着越来越重要的作用,那么嵌入式存储器与独立的存储器芯片在设计上存在着哪些差异?对此本文将以NOR型闪存为例在制造工艺的选取、衍生产品的设计、功耗与噪声、后端功能仿真、测试与修复等方面进行分析和研究。     

Depression in ethnically diverse women: Implications for treatment in primary care settings.

What do health care practitioners need to know about providing adequate care for depressed minority women? This article examined the prevalence of depressive symptoms and clinical depression in ethnic minorities, the extent to which current health service utilization is congruent with needs, and the effectiveness of treatments provided to ethnic minorities in the primary care setting. The impact of ethnic minority women's sociocultural context on symptom expression and help-seeking behavior is also discussed. Finally, the clinical implications for accurate assessment and treatment of ethnic minority women by both medical and mental health practitioners working in the primary care sector are addressed.

Daily impact of climate on the pattern of urban family life : Indigenous courtyard houses of Baghdad regions of the hot-dry climates Part I: Daily shifts or daily movements in summer

During the day, there are considerable variations in the climatic factors prevailing in these regions. This is especially so during the 24-hour daily cycle of the long, hot and dry summer (mid-May to midOctober). Such climatic conditions have had a considerable impact on the daily living pattern of family life in the same season, particularly in the urban areas. During the same 24-hour cycle, they have compelled the inhabitants to shift their living activities both vertically in section and horizontally in plan; they do this in pursuit of more acceptable, if not, desirable internal thermal environmental ambience.     

黄河下游滩区居民对安全的心理需求

黄河下游滩区居民对自身安全的需求非常强烈，具体表现在以下3个方面：对房屋采取垫高房台等安全措施，出于安全的原因愿意搬离现居住地，较高生育率与偏好男孩。他们建立在安全需求上的相应行为，增大了生活成本，影响着他们生存发展的空间，进而制约着滩区社会经济的发展。     

An alcohol expectancy-challenge prevention program for at risk college women.

Alcohol expectancy-challenge programs are effective in changing expectancies and reducing drinking in college men (J. Darker & M. S. Goldman. 1993. 1998); however, recent evidence suggests this protocol might not be effective for women (M. E. Dunn, C. Lau, & I. Y. Cruz, 2000). This study was designed to reevaluate the effectiveness of a social/sexual expectancy-challenge intervention in college women reporting moderate to heavy alcohol use. Forty-six undergraduate women were randomly assigned to the prevention or control condition. Participants reported alcohol expectancies at pre- and posttest and monitored their drinking patterns daily for 6 weeks. The program was effective in changing some expectancies but did not reduce drinking. This further confirms differences in the mechanisms by which expectancy-challenge programs function for men and women. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Encapsulated yeast cells inside Paramecium primaurelia: a model system for protection capability of polyelectrolyte shells

One of the most promising applications of encapsulated living cells is their use as protected transplanted tissue into the human body. A suitable system for the protection of living cells is the use of nano‐ or microcapsules of polyelectrolytes. These shells can be deposited easily on top of the cells by means of a layer‐by‐layer technique. An interesting feature of the capsules is the possibility to control their properties on a nanometre level, tuning their wall texture via the preparation conditions. Here we introduce a model system to test the protection ability of polyelectrolyte capsules. Common bakery yeast cells were encapsulated. They were coated with a fluorescently labelled shell at conditions known to guarantee cell survival, and the cell interior was stained with DAPI. The protozoan Paramecium primaurelia was incubated with this double‐stained living yeast and visualized by means of two‐photon excitation fluorescence microscopy. Cross‐sections of the dye‐stained material as well as autofluorescence of the fixed protozoan allowed us to follow the digestion of the coated yeast with time. Our investigation reveals that capsules prepared under these deposition conditions are permeable to lysosomal enzymes, leading to degradation of the yeast inside the intact capsules. Our preliminary results indicate the suitability of the introduced model as a test system of this permeability.

Biofiltration of toluene in the absence and the presence of ethyl acetate under continuous and intermittent loading

BACKGROUND: Two peat biofilters were used for the removal of toluene from air for one year. One biofilter was fed with pure toluene and the other received 1:1 (by weight) ethyl acetate:toluene mixture. RESULTS: The biofilters were operated under continuous loading: the toluene inlet load (IL) at which 80% removal occurred was 116 g m^?3 h^?1 at 57 s gas residence time. Maximum elimination capacity of 360 g m^?3 h^?1 was obtained at an IL of 745 g m^?3 h^?1. The elimination of toluene was inhibited by the presence of ethyl acetate. Intermittent loading, with pollutants supplied for 16 h/day, 5 days/week, did not significantly affect the removal efficiency (RE). Biomass was fully activated in 2 h after night closures, but 6 h were required to recover RE after weekend closures. Live cell density remained relatively constant over the operational period, while the dead cell fraction increased. Finally, a 15 day starvation period was applied and operation then re‐started. Performance was restored with similar re‐acclimatization period to that after weekend closures, and a reduction in dead cell fraction was observed. CONCLUSION: This study demonstrates the capacity of the system to handle intermittent loading conditions that are common in industrial practices, including long‐term starvation.
