this study was conducted to investigate the effect of organic and bio-fertilizers on trifluralin durability.herbicide persistence is an important consideration in crop production since residue levels of trifluralin herbicides can persist to the next growing season and may injure sensitive crops in the rotation. residues of trifluralin persist in the soil for long periods. extremely small amount...

The use of plasma-derived and recombinant coagulation factors for the treatment of haemophilia A and B is well established and permits patients to live a relatively normal life. In order to improve treatment options, several products are in development, which have a prolonged duration of action, thus enabling less frequent prophylactic dosing and aiming to reduce the burden of treatment. Severa...

An understanding of the half-life (T1/2) of infused fluids can help prevent iatrogenic problems such as volume overload and postoperative interstitial oedema. Simulations show that a prolongation of the T1/2 for crystalloid fluid increases the plasma volume and promotes accumulation of fluid in the interstitial fluid space. The T1/2 for crystalloids is usually 20 to 40 min in conscious humans b...

In order to determine the half-life of the 130Te double /?-decay, the amounts and isotopic composition of xenon extracted from tellurium ores, from the Oya gold mine in Japan, have been measured with a high-sensitivity mass spectrometer. Compared with atmospheric xenon an excess was definitely found at mass numbers 129, 130 and 131 in the extracted xenon. The excess of 130Xe is predominant, the...

As part of our program [1] to test CKM unitarity via superallowed ∃-decays, we reported in last year’s Progress Report [2] that we were well advanced in making a measurement of the half-life of Mg. At that time we had obtained a preliminary result but had not yet fully explored all possible systematic errors. Subsequently, an additional experiment was performed at the MARS spectrometer with our...

Protein turnover critically influences many biological functions, yet methods have been lacking to assess this parameter in vivo. Here, we demonstrate how chemical labeling of SNAP-tag fusion proteins can be exploited to measure the half-life of resident intracellular and extracellular proteins in living mice. First, we demonstrate that SNAP-tag substrates have wide bioavailability in mice and ...
