A biosensor for monitoring acetonitrile was constructed. A mixed culture was taken from a degradation reactor and mounted on top of a Clark electrode. The amperometric biosensor was placed in a flow-through cell and integrated into a flow injection system. The metabolic response in terms of oxygen consumption was well correlated to the concentration of acetonitrile in standard solutions. However,
A flow injection cell-based biosensor was constructed for 2,4-dichlorophenol (DCP) analysis by using a Clark-type oxygen electrode as a transducer. A mixed bacterial culture capable to biodegrade DCP was immobilized between a Teflon membrane and a dialysis membrane and attached to the oxygen electrode. Optimization of the flow rate, the injection volume, the carrier buffer concentration, and pH wa
We construct Gelfand-Tzetlin coordinates for the unitary orthosymplectic supergroup UOSp(k(1)/2k(2)). This extends a previous construction for the unitary supergroup U(k(1)/k(2)). We focus on the angular Gelfand-Tzetlin coordinates, i.e., our coordinates stay in the space of the supergroup. We also present a generalized Gelfand pattern for the supergroup UOSp(k(1)/2k(2)) and discuss various implic
X-linked agammaglobulinemia (XLA) is a hereditary immunodeficiency caused by mutations in the gene encoding Bruton tyrosine kinase (BTK). XLA patients have a decreased number of mature B cells and a lack of all immunoglobulin isotypes, resulting in susceptibility to severe bacterial infections. XLA-causing mutations are collected in a mutation database (BTKbase), which is available at http://bioin
We consider the reliability function of Markov channels with feedback and variable length channel codes. We extend Burnashev's [3] classic result to this case and present a single letter characterization for the reliability function.
Urban landscapes, structures and design features are associated with travel mode choice and have implications for sustainable living environments. The particular role of the built environment for children’s independent active mobility has received increasing attention in research and practice. However, the complexity of the transactions between person and environment needs to be understood with sp
We establish the Hasse principle for smooth projective quartic hypersurfaces of dimension greater than or equal to 28 defined over Q.
In the foreword to the Mercure de France edition of de Staël. (1996 [1793]. Réflexions sur le procès de la reine. Paris: Mercure de France), Chantal Thomas, French historian and writer, writes that this apology in favor of Marie-Antoinette did not help the queen nor the author herself; on the contrary it only made the latter more unpopular. So why did Germaine de Staël write it? Mme de Staël and M
We evaluate the distribution of waiting times between electrons emitted by a driven mesoscopic capacitor. Based on a wave packet approach we obtain analytic expressions for the electronic waiting time distribution and the joint distribution of subsequent waiting times. These semi-classical results are compared to a full quantum treatment based on Floquet scattering theory and good agreement is fou
The electrical charge limit of crystallizing sodium chloride droplets has been studied. Moderately charged sodium chloride solution droplets were dried to highly charged residual particles. The charge limit was found to be near the Rayleigh charge limit for saturated sodium chloride droplets of the same size as the residual particle. The charge loss was not found to affect the particle size to a d
We summarise the main features of VINCIA's antenna-based treatment of QCD initial- and finalstate showers, which includes iterated tree-level matrix-element corrections and automated evaluations of perturbative shower uncertainties. The latter are computed on the fly and are cast as a set of alternative weights for each generated event. The resulting algorithm has been made publicly available as a
Despite academic advances in PID controller design and development of automatic tuning procedures, there are still many PID controllers that are badly tuned, or not even tuned at all, in process industry. There are several reasons for this, but one major reason is that it is considered too time consuming to use current PID controller tuning methods. This paper presents a new tuning method that is
A method for the prevention of thrombotic, embolic and/or hemorrhagic disorders, such as cerebral infarction (stroke) or myocardial infarction, by administering levosimendan or its metabolite (II) or any of their pharmaceutically acceptable salts to a mammal in need of such prevention
Background: Transient tachypnea of the newborn is characterized by tachypnea and signs of respiratory distress. Transient tachypnea typically appears within the first two hours of life in term and late preterm newborns. Although transient tachypnea of the newborn is usually a self limited condition, it is associated with wheezing syndromes in late childhood. The rationale for the use of salbutamol
