For many filamentous fungi spherical growth may only be expressed during the formation of spores and many yeast-like fungi have only the remnants of a true filamentous growth habit. However, the many shapes and forms found among the 64 000 recognized species of fungi are by and large generated by employing these two basic patterns of cell wall expansion. The dimorphic fungi are taken to represent those organisms in which the equilibrium between polarized and spherical growth is such that vegetative growth can occur in either a hyphal or budding mode according to environmental conditions. The term dimorphism is a misnomer since many of the so-called dimorphic fungi produce a variety of cell forms and therefore are really polymorphic.

Percolation phase transitions in central heavy ion collisions are predicted and methods to form and to investigate such baryon rich matter are suggested.
The structure of the hetemnuclear iron acetate [Fe2CoO(CH3COO)6(3-Cl-Py)3]·1/4· 3-Cl-y× 1/4(CH3)2... more The structure of the hetemnuclear iron acetate [Fe2CoO(CH3COO)6(3-Cl-Py)3]·1/4· 3-Cl-y× 1/4(CH3)2CO· 1/2H2O was determined by X-ray structure analysis. The crystal has a molecular structure and is monoclinic with lattice parameters a = 21.034(4). b = 8.398(2), c = 23.360(5) Å, β= 98.28(3)‡, R = 0.0656. space group P21/c. The trinuclear complex [Fe2CoO(CH3COO)6(H2O)3] has a structure typical for iron(III) μ3-O compounds with iron atoms hing at the vertices of the equilateral triangle centered by an oxygen atom. The metal atoms are each coordinated to four oxygen atoms of the four bridging carboxy groups, the bridging oxygen atom (μ3-O), and the coordinated 3-chloropyridine molecule which is trans relative to the latter atom. According to Mössbauer spectroscopy data, the iron(III) ions are in the high-spin state. The value of (μef)mole/μ3 at room temperature and its temperature dependence suggest that the resulting magnetic exchange interaction between the paramagnetic centers of the cluster is antiferromagnetic.
