Based on the BOD, Metcalf and Eddy (2003) classified raw domestic wastewater as low strength or weak (110 mg L−1), medium strength (200 mg L−1) and strong (400 mg L−1).
It has strong positive loadings on NO3 and Cl and weak loadings on Mg and Na.
Akerstedt et al. (15) examined human sleep after an acute exposure of a relatively weak field (10 mG).
However, such atomic motions are much weaker in Cu46Zr46Al8 MG, due to higher activation energies.
These patients received an intravenous infusion of the weak opioid tramadol (500 mg) in combination with the spasmolytic butylscopolamine (50 mg) immediately after the surgery until the morning of first postoperative day.
Increasing Cu content can produce a similar phenomenon, but with weak effects compared with Mg.
In contrast, samples from QH, HB, and MG have weak correlations between these two parameters, which indicates a wider grain size distribution of magnetic particles from these sites.
Passive injections of glucose increased its levels in the NAc, but the increase was relatively weak: ∼50 μM for 30 mg and ∼170 μM for 60 mg injections.
The weak signals from the MG-150 suggested poor crystallization quality and the presence of rich defects.
A subcutaneous depot (1 mg) produced weaker labelling, but individual cells could still be detected, whereas i.v. (1 mg) delivery produced only very faint staining.
For this purpose, 50 mg of the weak cation exchanger Dowex 50 WX8 and 50 mg of the weak anion exchanger Dowex 1 × 8 (both from Serva, Heidelberg, Germany) were packed together in a Bakerbond glass cartridge (3 mL; JT Baker, Deventer, The Netherlands) between two Teflon frits.
