Dear Editor, erythrocyte sedimentation rate (ESR) is a useful basic clinical pathology laboratory investigation. It can be helpful in diagnosis and follow-up of several diseases. At present, a new automated method with proven reliability is available for ESR test  (1). Here, the authors report on observation on a laboratory experiment to test the effect of zinc nanoparticles on ESR results. The...

allelopathy is the main factor of weed interference on growth and development of crops. in order to study of allopathic effect of hoery cress organs extrate on germination and seedling growth of triticale, two separate factorial experiment based on randomized complete block design with four replication were conducted under laboratory and green house conditions. treatment were included of extrac...

Several European countries and Japan are in various stages of privatizing and/or introducing more competition in passenger rail service. This process has been furthered in Europe by a directive from the Commission of the European Communities (1991) requiring member states to separate operations from infrastructure on the books and give international groupings of trains access to their infrastru...

For experiments to be reproducible, it is important to have a known and controlled environment. This requires isolation from the surroundings. For security experiments, e.g. with hostile software, this is even more important as the experiment can affect the environment in adverse ways. In a normal campus laboratory, isolation can be achieved by network separation. For an online environment, whe...

An underdense plasma-lens experiment is planned at the UCLA Neptune Laboratory. For this experiment, a LaB6based discharge plasma source was developed and tested. Test results of the plasma source show that it can provide satisfactory argon plasma parameters for underdense plasma lens experiments, i.e., a density in low 10 cm 3 range and a thickness of a few cm. In the plasma chamber a YAG slab...

An experiment demonstrating changes in the fatty acid composition of bacterial membranes from bacteria grown at 22 and 373C is described. The changes in composition con"rm expected generalizations. The isolation method is simple and provides samples of fatty acid methyl esters ready for gas chromatography-mass spectroscopy (GC-MS) analysis within about 1.5 h. Analysis by GC-MS involves the use ...

In this paper we study the effects of acute stress on speculative behavior using a controlled laboratory experiment with 208 healthy subjects. We employ a recently introduced measure that captures individual speculative behavior, the Speculation Elicitation Task, and an efficient stress-inducing procedure, the Trier Social Stress Test for Groups, and pay special attention to the gender-specific...

In a nutshell, price cap regulation is meant to establish a quid pro quo: regulators are obliged by law to intervene only at rare, previously defined points in time, and only by imposing an upper bound on prices; firms aremeant to justify regulatory restraint by adopting socially beneficial innovations. In the policy debate, a potential downside of the arrangement has featured less prominently:...

Hydrothermal processes on Mars: It has been suggested that hydrothermal process may have been active in the history of Mars[1]. This concept is supported by three lines of evidences: (1) widespread evidences of volcanic activity on Mars; (2) high levels of WEH (water-equivalent-hydrogen) found in two large equatorial regions on Mars (ODY_NS) [2]; (3) The ground ice excavated by meteorite impact...
