This paper presents an evaluation of the energy intensity and related greenhouse gas/CO2 emissions of integrated oil sands crude upgrading processes. Two major oil sands crude upgrading schemes currently used in Canadian oil sands operations were investigated： cokingbased and hydroconversion-based. The analysis, which was based on a robust process model of the entire process, was constructed in Aspen HYSYS and calibrated with representative data. Simulations were conducted for the two upgrading schemes in order to generate a detailed inventory of the required energy and utility inputs： process fuel, steam, hydrogen and power. It was concluded that while hydroconversion-based scheme yields considerably higher amount of synthetic crude oil （SCO） than the cokerbased scheme （94 wt-% vs. 76 wt-%）, it consumes more energy and is therefore more CO2-intensive （413.2kg CO2/m3sco vs. 216.4kg CO2/m^3sco）. This substantial difference results from the large amount of hydrogen consumed in the ebullated-bed hydroconverter in the hydroconversion-based scheme, as hydrogen production through conventional methane steam reforming is highly energy-intensive and therefore the major source of CO2 emission. Further simulations indicated that optimization of hydroconverter operating variables had only a minor effect on the overall CO2 emission due to the complex trade-off effect between energy inputs.

Acne vulgaris is a common inflammatory disease of the pilosebaceous unit, with a profound impact on the quality of life of patients. In this work, we aimed to study the safety characteristics of CleodermTM, a novel functional semisolid vehicle developed for the compounding of treatments for acne and oily skin. The primary and cumulative irritation and sensitization potential were evaluated in 54 healthy volunteers in a comparative single-blinded study, while the acnegenic and comedogenic potential of the product were assessed in 31 healthy volunteers with combination to oily skin through a non-comparative study. CleodermTM was applied (0.05 g/cm2) in filter paper discs in both studies. For the evaluation of the irritation and sensitization potential, the investigational product, or a control (0.9% NaCl) was applied to the right or left scapular area of the study subjects. No clinical reactions were observed during the induction or challenge phases, suggesting that CleodermTM presents no irritating or allergenic potential. Regarding acnegenicity and comedogenicity, no significant increase in the number of acne lesions linked to the application of the product in four areas of the face was reported, indicating that CleodermTM appears not to display acnegenic and comedogenic potential. Furthermore, over 60% of the study subjects exhibited a decrease in the number of acne lesions after product use. These results show that CleodermTM exhibited no irritating, sensitizing, acnegenic or comedogenic potential, and suggest that it can be considered safe under the study conditions and that the claims dermatologically tested, clinically tested, and non-comedogenic/acnegenic can be supported.

桃红、柳绿、云白、天蓝,似乎一来到这个世界,我们就长久地生活在颜色的环绕之中。时尚消费、设计开发,甚至性格分析,随意走进一种领域,我们都不难发现,色彩的应用和渗透早已无孔不入。对于家具,一位意大利设计师在受访时,亦曾如此谈及:在同质化产品日渐增多的当今,色彩已成为产品脱颖而出的关键要素之一。一件色彩搭配得宜的产品,不仅具有更高的吸引力,还可以帮助识别公司,确立良好的品牌形象。那么,事实是否的确如此?心理学家的研究证实了这一观点:色彩对视觉的影响最大。看到不同的颜色,人的精神状态和心理情绪也会相应地受到不同的影响。即便地域、国度、民族、性格不尽相同,都一样通用此理。比如,在所有人的眼中,红黄都是暖色的代表,蓝紫是冷色的代言,黑白则作为中性色,被称为永恒的经典。正因为深深浅浅的色彩,带来明明暗暗的感受,人们在春夏秋冬、四季轮回的更替之间,运用色彩的功能,不厌其烦地耍玩着搭配的游戏,为生活增添了无穷的乐趣。

A closed linear relation T in a Banach space X is called left(resp. right) Fredholm if it is upper(resp. lower) semi Fredholm and its range(resp. null space) is topologically complemented in X. We say that T is left(resp. right) Browder if it is left(resp. right)Fredholm and has a finite ascent(resp. descent). In this paper, we analyze the stability of the left(resp. right) Fredholm and the left(resp. right) Browder linear relations under commuting Riesz operator perturbations. Recent results of Zivkovic et al. to the case of bounded operators are covered.
