Water balance for landfills of different age

Water-related processes in landfills are discussed with emphasis on internal processes such as field capacity, moisture variation in time and space, and macropore flow. Runoff production and evaporation from landfills in Sweden of different age are investigated. It is clarified in what ways and for how long a closed municipal landfill differs from an ordinary land area from a hydrological point of

Reduced risk of ventricular fibrillation by balancing sodium, calcium, potassium and magnesium added to nonionic contrast media. An investigation in the isolated rabbit heart

The effect of addition of calcium, potassium and magnesium to iohexol (350 mg I/ml) enriched with 30 mM sodium was investigated with regard to ventricular fibrillation (VF) in isolated rabbit hearts. Enriching iohexol containing 30 mM sodium with increasing amounts of calcium (0-1.2 mM) caused an increase in the frequency of VF. Increasing amounts of potassium (0-3.8 mM) to iohexol with 30 mM Na +

The human cornea proteome: bioinformatic analyses indicate import of plasma proteins into the cornea

Increased biochemical knowledge of normal and diseased corneas is essential for the understanding of corneal homeostasis and pathophysiology. In a recent study, we characterized the proteome of the normal human cornea and identified 141 distinct proteins. This dataset represents the most comprehensive protein study of the cornea to date and provides a useful reference for further studies of normal

Modifying a standard method allows simultaneous extraction of RNA and protein, enabling detection of enzymes in the rat retina with low expressions and protein levels

The aim of the study was to evaluate messenger RNA and protein expression in limited amounts of tissue with low protein content. The Chomczynski method was used for simultaneous extraction of RNA, and protein was modified in the protein isolation step. Template mass and cycling time for the complementary DNA synthesis step of real-time reverse transcription-polymerase chain reaction (RT-PCR) for a

Whitepaper: S88 for Universities

If you are working at a university teaching a course in automation, and/or process control or if you are a student in interested in those subjects 14 this paper is for you! You might already have heard about the S88 batch control standard 14 how it tries to define terminology and concepts that makes design and operation of process control plants easier. In this paper, we will try to briefly explai

Energy transfer within Zn-porphyrin dendrimers: Study of the singlet-singlet annihilation kinetics

In this article, we explore energy transfer processes within a series of Zn-porphyrin-appended dendrimers by means of excitation intensity dependent transient absorption measurements. We report singlet-singlet annihilation on two distinct time scales of 18 +/- 5 ps and 130 +/- 10 ps in the dimer and the dendrimers. The two distinct processes reflect the presence of two structural conformer distrib
