Serovars of Lisreria l1Iollocyrogelles were determined. Sera of aborted samples (200) were collected from different hospitals in Tehran and were tested serologically by immunofluorescent antibody methods (IF tests). 137 positive sera were identified. Positive sera were tested against 12 serovars of Listeria l1Iollocytogelles separately. Titers of antibody in patients' sera for all serovars ...

Bidding one’s value in a second-price auction with private valuations is a dominant solution (Vickrey, 1961). However, repeated experimental studies …nd much more overbidding than underbidding, resulting in overbidding on average. In our experimental work we introduce manipulations against which the dominant strategy is immune, yet they a¤ect bidding in a predictable way. The strong …nding sugg...

A set of 37 mutations in DnaK, the Escherichia coli homologue of the 70-kDa heat shock proteins, was isolated using a selection for high constitutive expression of heat shock proteins. Of these, 11 mutants were able to carry out some but not all functions of DnaK. These partial function mutants were divided into two classes. Class I mutants are recessive and permit replication of bacteriophage ...

Understanding the policy cycle, as well as scrutinizing the text of hidden and obvious policies and rules, requires a model of discourse analysis based on which discursive ap-proaches of policy makers are understood and estimated. However, when it comes to presenting a policy model, we have to use the views of policy theorists to see how a problem as a "public goods" can be found in the policy ...

The advantages of solving potential problems using an overdetermined boundary integral element method are examined. Representing a 2-dimensional potential solution by an analytic complex function forms two algebraic systems from the real and imaginary parts of the discretized form of the Cauchy theorem. Depending on which boundary condition is prescribed, the real or the imaginary algebraic sys...

A family suffering from cranial diabetes insipidus, that extends over 4 generations, is described. Inheritance of polyuria was autosomal dominant. Vasopressin function was studied in members of the last 2 generations, 4 of whom had polyuria. Osmoregulation of vasopressin secretion was assessed by infusion of hypertonic saline. Plasma vasopressin remained undetectable in one patient, while 2 oth...

Oceanic conditions play an important role in determining the effects of climate change and these effects can be monitored through the changes in the physical properties of sea water. In fact, Oceanographers use various probes for measuring the properties within the water column. CTDs (Conductivity, Temperature and Depth) provide profiles of physical and chemical parameters of the water column. ...
