Critical assessment of gassing-in methods for measuring k(l)a in fermentors.

Biotechnology and bioengineering

Linek V, Sinkule J, Benes P.
PMID: 18600768
Biotechnol Bioeng. 1991 Aug 05;38(4):323-30. doi: 10.1002/bit.260380402.

The reliability of dynamic measurement methods of k(l)a in fermentors using a step oxygen concentration change in the feed gas was tested. The tests were performed both for the original variant using the nitrogen right harpoon over left harpoon...

Comments on validity of dynamic measuring methods of oxygen diffusion coefficients in fermentation media with polarographic oxygen electrodes.

Measurement of k(L)a by dynamic pressure method in pilot-plant fermentor.

Biotechnology and bioengineering

Linek V, Moucha T, Dousová M, Sinkule J.
PMID: 18615744
Biotechnol Bioeng. 1994 Mar 15;43(6):477-82. doi: 10.1002/bit.260430607.

The dynamic pressure method (DPM) is used for measurement of k(L)a in a 1-m(3) pilot scale fermentor in coalescing (distilled water) and noncoalescing (0.3 M Na(2)SO(4) aqueous solution) batches. The method consists in recording oxygen concentration in a batch...

Check for consistency of experimental determination of transient characteristics of oxygen probes with significant liquid film resistance.

Biotechnology and bioengineering

Linek V, Vacek V, Sinkule J.
PMID: 18548732
Biotechnol Bioeng. 1983 Apr;25(4):1195-200. doi: 10.1002/bit.260250427.

Critical assessment of the steady-state Na2SO3 feeding method for kla measurement in fermentors.

Biotechnology and bioengineering

Linek V, Benes P, Sinkule J.
PMID: 18592576
Biotechnol Bioeng. 1990 Apr 05;35(8):766-70. doi: 10.1002/bit.260350803.

Important aspects of k(l)a measurement in agitated aerated vessels are briefly characterized from the standpoint of reliability of the measured data. It seems that most of the k(l)a data, based on a number of variants of the steady-state and...

Designing websites for persons with cognitive deficits: Design and usability of a psychoeducational intervention for persons with severe mental illness.

Psychological services

Rotondi AJ, Sinkule J, Haas GL, Spring MB, Litschge CM, Newhill CE, Ganguli R, Anderson CM.
PMID: 26321884
Psychol Serv. 2007 Aug;4(3):202-224. doi: 10.1037/1541-1559.4.3.202.

The purpose of this study was to develop an understanding of the design elements that influence the ability of persons with severe mental illness (SMI) and cognitive deficits to use a website, and to use this knowledge to design...

Transient characteristics of oxygen probes with significant liquid film effects.

Biotechnology and bioengineering

Linek V, Vacek V, Benes P, Sinkule J.
PMID: 18587842
Biotechnol Bioeng. 1989 Jan 05;33(1):39-48. doi: 10.1002/bit.260330107.

Various experimental procedures for the determination of transient characteristics with significant liquid film effects were tested. A comparison between transient characteristics obtained experimentally and those calculated from rational models indicates that all procedures but one give highly inconsistent results....

Oxygen electrode dynamics: three-layer model--chemical reaction in the liquid film.

Biotechnology and bioengineering

Linek V, Sinkule J, Vacek V.
PMID: 18548768
Biotechnol Bioeng. 1983 May;25(5):1401-18. doi: 10.1002/bit.260250518.

A general model of the transient behaviour of an oxygen probe is derived on more general assumptions than those previously considered. The present state of the art is shortly discussed in its relation to the newly derived equations: (1)...

Physiologic Effects from Using Tight- and Loose-Fitting Powered Air-Purifying Respirators on Inhaled Gases, Peak Pressures, and Inhalation Temperatures During Rest and Exercise.

Journal of the International Society for Respiratory Protection

Sinkule EJ, Powell JB, Rubinstein EN, McWilliams L, Quinn T, Pugliese M.
PMID: 32336877
J Int Soc Respir Prot. 2016;33(2):36-52.

The goal of this investigation was to evaluate the physiologic stresses of powered air-purifying respirators (PAPRs) used by workers in many industries (e.g., health care, automobile repair, public safety, building trades, etc.) during rest and three levels of energy...
