通过室内实验研究了疏水化聚乙二醇(PEG)/K^(+)体系抑制页岩水化的作用机理。通过岩屑热滚分散实验、膨润土性能测试和接触角测量,发现抑制剂体系的抑制能力随着接触角的增加和PEG浓度的增加而增强。改进岩屑热滚分散实验表明抑制剂并未通过热活化钻井液乳化机理(TAME)机制发生作用。通过吸附量、傅立叶变换红外光谱(FT-IR)、X射线衍射(XRD)图谱和热重分析(TGA)研究了PEG/K^(+)体系与黏土样品的相互作用,吸附等温线分析表明K^(+)的存在增加了PEG对黏土表面的亲和力。FT-IR光谱、热重和微商热重分析证明,PEG的吸附可以减少黏土的含水率,即抑制性良好;XRD图谱分析K^(+)的存在使PEG的插层仅为一层,且连接在PEG链上的疏水尾增强了抑制水化的能力。最后采用添加PEG/K^(+)的水基钻井液进行了岩屑热滚分散实验,验证了PEG/K^(+)体系的抑制性能。

Traditionally, search engines are designed to support a single user working alone. However, the construction of knowledge is enriched when one adds collaboration to search tasks. We identified opportunities for remote collaboration in a Social Web search model that integrates parents and children guided by 5W + 1H (who, what, where, when, why, how) dimensions. Our social search model aims at improving the search process for children. We found 7 opportunities for remote collaboration on the search process, based on implicit-explicit interactions.

Results of analytical surveys on pesticide residue levels in foods for the years 1986-1987 are presented. Analytical data obtained from regional laboratories are tabulated in terms of various commodity groups (vegetables, fruit, cereals, processed or derived foodstuffs, other commodities, legumes, environmental samples, others) and are compared with maximum legal tolerances established by the ministerial ordinance (Italian Ministry of Health) 6.6. 1985.On a total number of 4715 determinations of classes of compounds or of single compounds made on 1601 commodities samples, only N 53 (1.1 %) violative results appeared. No residue was found at levels exceeding regulatory limits or found in commodities where a tolerance had not been established for a specific pesticide/commodity combination.

The kallikrein-kinin system(KKS) is an intricate endogenous pathway involved in several physiological and pathological cascades in the brain. Due to the pathological effects of kinins in blood vessels and tissues, their formation and degradation are tightly controlled. Their components have been related to several central nervous system diseases such as stroke, Alzheimer's disease, Parkinson's disease, multiple sclerosis, epilepsy and others. Bradykinin and its receptors(B1R and B2R) may have a role in the pathophysiology of certain central nervous system diseases. It has been suggested that kinin B1R is up-regulated in pathological conditions and has a neurodegenerative pattern, while kinin B2R is constitutive and can act as a neuroprotective factor in many neurological conditions. The renin angiotensin system(RAS) is an important blood pressure regulator and controls both sodium and water intake. AngⅡ is a potent vasoconstrictor molecule and angiotensin converting enzyme is the major enzyme responsible for its release. AngⅡ acts mainly on the AT1 receptor, with involvement in several systemic and neurological disorders. Brain RAS has been associated with physiological pathways, but is also associated with brain disorders. This review describes topics relating to the involvement of both systems in several forms of brain dysfunction and indicates components of the KKS and RAS that have been used as targets in several pharmacological approaches.
