purpose: in order to express human granulocyte-macrophage colony stimulating factor (hgm-csf) under heat shock. materials and methods: two expression plasmids were constructed based on pbc(sk) plasmid. the expression cassettes in the two plasmids are equipped with a 75 base pair fragment, derived from the pl promoter of the bacteriophage lambda (λ). the plasmids also contain a temperature muta...

In this paper, we report on measurements of the specific heat C of single-crystalline EuxSrl_xTe at temperatures between 60 mK and 15 K and in magnetic fields up to 6 T. Pure antiferromagnetic EuTe shows unusual critical behavior in the vicinity of the N6el temperature T N = 9.8 K with a positive critical exponent instead of the 3d-Heisenberg exponent c~---0.12. Possible reasons for this discre...

The present study extends the Einstein model for heat capacity of solids to nanoclusters. In the case of small phases the contribution of surface energy to overall thermodynamic properties of the system is essential. On that physical background, the heat capacity depends on the size of cluster through its interface energy. Employing the same relation between Einstein temperature and the cluster...

a specific polymerase chain reaction (pcr) method was applied for identification of bovine (bos taurus), ovine (ovis aries) and caprine (capra hircus) pure and binary mixtures of raw and heat-processed meats. these meats are used in food industry products and/or for direct consumption of consumers. the mitochondrial dna was amplified as a template in a pcr reaction by use of specific primers re...

The susceptibility and specific heat experimental results of the diluted magnetic semiconductors (DMS) are incorporated in a model based on short-range as well as long-range interaction in a random may of magnetic ions. The so-called nearestneighbor pair approximation (NNPA) is applied. It appears that the calculated values of zero field specific heat and Curie-Weiss temperature based on th...
