RESIDUAL GENTAMICIN ON A MILLIPORE MEMBRANE WAS INACTIVATED BY MODIFICATION WITH TWO DIFFERENT ENZYMES: gentamicin adenylyltransferase and 3-N-acetyltransferase. Both modifications allowed the growth of susceptible strains of Escherichia coli and Bacillus subtilis.

The migration in vitro of neutrophils from six patients with monosomy-7 or partial deletion of the long arm of chromosome 7 was studied by two methods: the Millipore filter assay and the migration under agarose assay. Four of the patients had preleukemia, one had subacute myelomonocytic leukemia, and one polycythemia vera. In four patients, chemotaxis (migration towards a higher concentration o...

In this note, we introduce the concept of a fuzzy filter of a BLalgebra,with respect to a t-norm briefly, T-fuzzy filters, and give some relatedresults. In particular, we prove Representation Theorem in BL-algebras. Thenwe generalize the notion of a fuzzy congruence (in a BL-algebra) was definedby Lianzhen et al. to a new fuzzy congruence, specially with respect to a tnorm.We prove that there i...

Background and Objectives: In the most Iranian hospitals the internal air is cooled by a system comprising centrifugal blower fan and excelsior filters. Because amoeba can be present in air and dust it may enter into filters of cooling systems. It has been suggested that diffusion of amoebae cyst through air canals may contribute to various types of nosocomial infections. This ...

an air filter is a significant element of any mechanical ventilation system. however, the importance and performance evaluation of air filters have not been well publicized and related scientific reports are scarce. in this study, a transportable, off-line, air filter-testing unit (the unit) was designed and utilized to simulate the filter housing of a mechanical ventilation system. the unit wa...

The development of numerical techniques now permits us to analyze complex structures such as dielectric resonator filters and planar passive elements for coplanar monolithic microwave integrated circuits. In this paper, we describe a novel method for designing dielectric resonator filters. Then a Chebychev band pass filter is designed by coaxially placing high-Q TM01Q dielectric resonators ...

one hundred and twenty two blood samples from patients with ami and aci were analyzed for glucose, cholesterol, triglyceride by colorimetric method, and for lipoprotein by millipore agaro-slide electrophoretic technique. the results presented in this communication indicated that patients with ami and acd had higher abnormal gtt than that of the controls. the cholesterol and triglyceride levels ...
