非综合铁水厂中的脱磷工艺

在大多数情况下，非综合铁水厂生产的铁水出炉后不经过任何额外的精炼处理。所以，铁水中一些有害元素（例如，磷）的含量就完全决定于原料的质量了。由于高炉铁水生产工艺没有提供用炉渣去磷的热力学条件，所以铁水中含有由木炭和铁矿带来的所有的磷。无磷高质原料的不可行性和无磷铁水的高市场价值导致ＭＧＳ公司的Ｓete Lagoas厂采用了铁水包脱磷工艺。为了避免环境污染问题，该厂选择了使用浸入式喷枪的石灰为熔剂和铁水包表面吹氧技术的脱磷工艺。本文描述了脱磷工艺过程和一些操作结果。本文描述了脱磷工艺过程和一些操作结果。可以技术性地总结为：以石灰为溶剂的铁水脱磷工艺具有可行性；而且，通过适当的工艺控制系统达到操作优化也是非常重要的。

Inferences in therapy: Processes and hazards.

Psychotherapists are constantly involved in the process of forming hypotheses about clients. These hypotheses are a combination of direct observation and inferred information. This study considered how 9 therapists made inferences during hypothesis formation. They made restructuring and supplemental inferences in about half of their comments about the client in an initial session. As was expected, they made inferences based on obviously missing information. This study also reveals that therapists make inferences based on other inferences that over time were remembered and used as direct observations. Precautions are offered for clinicians and therapist-educators in working with inferential information. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The use of alcohol by lesbians: a review and research agenda

This article reviews the literature on alcohol use by lesbians. Comparisons of data on lesbians and women from the general population show that lesbians tend to drink more than other women; that rates of drinking do not decline with age as is true for general population women; and that even when levels of drinking are equivalent between lesbians and general population women, lesbians report greater difficulties related to alcohol consumption. Differences in sampling techniques and differences in definitions of drinking among the papers made comparisons of results difficult. These issues are discussed and recommendations are made concerning standardization of data collection.     

Production and characterization of profilin monoclonal antibodies

To evaluate the hypothesis that self-paced movements are mediated primarily by the supplementary motor area, whereas externally triggered movements are mainly affected by the lateral premotor cortex, different movements in 6 healthy volunteers were studied while changes in regional cerebral blood flow (rCBF) were measured using positron emission tomography (PET) and 15O-labeled water. Subjects made a series of finger opposition movements initiated in a self-paced manner every 4 to 6 seconds, and separately, made continuous finger opposition movements at a frequency of 2 Hz paced by a metronome. The primary motor cortex, lateral area 6, cerebellum on both sides, and caudal cingulate motor area, and the putamen and thalamus on the contralateral side were more active during the metronome-paced movements. The increases in rCBF in these areas are likely the result of the larger number of movements per minute made with the externally triggered task. The anterior supplementary motor area and rostral cingulate motor area in the midline, prefrontal cortices bilaterally, and lobus parietalis inferior on the ipsilateral side were more active during the self-paced movements. Increases in rCBF in those areas, which include medial premotor structures, may be related to the increased time devoted to planning the movement in this condition.
