Received: 09/10/02; accepted: 14/09/03 ABSTRACT Candida dubliniensis is an emerging yeast pathogen isolated mainly from immunocompromised patients. As molecular tests are currently unsuitable for use in routine diagnostic laboratories, we compared a variety of phenotypic techniques for differentiating C. albicans and C. dubliniensis. The tests included: colony colour on CHROMagarTM Candida medium; growth at 37 °C and 45 °C; ability to produce germ tubes and chlamydospores; and the Auxacolor® system. The organisms included 105 isolates previously identified as C. albicans, 10 reference strains of C. albicans, 2 reference strains of C. dubliniensis and 102 fresh clinical isolates identified as C. albicans. None of the tests alone was satisfactory but a combination of 3 tests may be suitable for presumptive identification of C. dubliniensis.

Identification and Control of MIMO Systems with State Time Delay (Short Communication)
Time-delay identification is one of the most important parameters in designing controllers. In the cases where the number of inputs and outputs in a system are more than one, this identification is of great concern. In this paper, a novel autocorrelation-based scheme for the state variable time-delay identification for multi-input multi-output (MIMO) system has been presented. This method is ba...

A new iterative learning controller is proposed for a general unknown discrete time-varying nonlinear non-affine system represented by NARMAX (Nonlinear Autoregressive Moving Average with eXogenous inputs) model. The proposed controller is composed of an iterative learning neural identifier and an iterative learning controller. Iterative learning control and iterative learning identification ar...

Plant growth promoting rhizobacteria (PGPR) are known to influence plant growth by various director indirect mechanisms. Thirty–two strains were isolated from 15 soils sampled in central Iran, byusing and comparing three different methods. The screening of soil samples by means of soil paste–plate method combined with isolation on mannitol agar proved to be the best strategy in terms ofreliabil...

Two strains, HG104 and ASSO, were isolated Crom the soil of Tehran's suburbs. Taxonomic studies showed thatHG104 and AS50 belong to Mycobacterium spp. and Brevibacterium spp. respectively, which produce antibacterial substances with relatively high activity against some important clinical Gram-positive and Gramnegative bacteria
