Mothers adoption studies

Related to twin studies are so-called adoption studies, which examine the IQ scores of children who were adopted early in life and compare their scores with the IQ scores of both their natural and their adoptive mothers. The adopted child and its... 

Declining serum prolactin concentrations cause a decrease in or cessation of lactation, and this can be problematic, as well as distressing, for mothers who desire to breast-feed their infants. Relactation is the process of increasing the breast milk supply for such women. Lactation also can be induced in women who have not recently delivered a baby, such as adoptive mothers. The mainstay of therapy for this condition involves nipple stimulation either by the infant s nursing or by pumping of the breast with a mechanical pump or the hand. One small study showed that a substance in beer and nonalcoholic beer can stimulate prolactin secretion and thus increase milk production. ... 

Chau and his co-workers have proposed some wavelet-based methods to compress UV-VIS spectra [24,37]. In their work, a UV-VIS spectrum was processed with the Daubechies wavelet function, Djfi. Then, all the Cj elements and selected Dj coefficients at different) resolution levels were stored as the compressed spectral data. A hard-thresholding method was adopted for the selection of coefficients from Dj. A compression ratio up to 83% was achieved. As mentioned in the previous section, the choice of mother wavelets is vast in WT, so one can select the best wavelet function for different applications. Flowever, most workers restrict their choices to the orthogonal wavelet bases such as Daubechies wavelet. Chau et al. chose the biorthogonal wavelet for UV VIS spectral data compression in another study [37]. Unlike the orthogonal case, which needs only one mother wavelet (p(t), the biorthogonal one requires two mother wavelets. (p(t) and (p(t), which satisfy the following biorthogonal property [38] ...
