For analysis of multicomponent mixtures using linear regression algorithms, a qualitative detection of the analytical sample must be made to ascertain the exact nature of coexisting species in the mixture. The most frequently occurring cases in analytical practice is that the range of possible coexisting species is known and a decision has to be made which species actually coexist in the sample. This paper describes a new chemometric method based on bound-branch approach to solve this problem which has...

For analysis of multicomponent mixtures using linear regression algorithms, a qualitative detection of the analytical sample must be made to ascertain the exact nature of coexisting species in the mixture. The most frequently occurring cases in analytical practice is that the range of possible coexisting species is known and a decision has to be made which species actually coexist in the sample. This paper describes a new chemometric method based on bound-branch approach to solve this problem which has been turned to the problem of selecting the optimal subset for regression. The computation time is much less than the enumeration procedure and there is no risk of missing the real combination of the coexisting components in the sample. A program written in True BASIC has been testified for UV and fluorescence spectrophotometric analyses of mixtures containing various possible coexisting organic compounds with satisfactory analytical results.

The exact nature and acquisition mechanim of the remanent magnetization and the exactorigin of the enhanced magnetic properties of the palaeosols are two main problems in theretrieval of climatic and environmental data of the past extracted from the loess-palaeosol se-quences in China by means of their magnetic properties.Magnetic investigation of the Malan and Lishi Formations mainly in Luochuan and Jixianloess sections shows that:1) The palaeosols differentiate from the parent loess not only by theirenhanced magnetic susceptibility but also by their pronounced natural remanent magnetizationand laboratory-induced remanences;2) The suceptibility and natural magnetization variationscan be mainly attributed to the concentration changes of the primary magnetic minerals,to theeffective grain-size changes and to the authigenesis of strong magnetic minerals (magnetiteand/or maghemite),all of which are induced by climatically controlled pedogenic processes;3) The main remanence in loess layers are magnetite and haematite and in palaeosols are mag-netite,maghemite,haematite and geothite;4) The variation in magnetic properties in loesscan be considered as proxy signals of the climatic changes and may be a semi-quantitative de-scription of the latter and can not be a measure of time.

Sections of 30 cases of human cirrhosis were stained by' rabbit antibody to insulin -like growth factor Ⅱ using PAP technique. 50% of the sera of the patients showed HBV infection and 47% of the liver tissues were HBsAg positive. The IGF-2 immunoreactive product was demonstrated in the cytoplasm of all liver and ductular cells. The polypoid and binucleated liver cells were labelled stronger. A kind of thin, polygonal liver cells with one or two round or oval and deeply stained nuclei frequently stained strongly positive. They might exist either irregularly in the lobule or the nodule differing from the so-called oval cell. Their exact nature are going to be deter mined.
