An apparatus was designed for simultaneous measurement of rates of N(2) fixation estimated by C(2)H(2)-C(2)H(4) assay (N(2)[C(2)H(2)] fixation) and NO(3) (-) absorption by roots of intact, nodulated soybeans (Glycine max [L.] Merr.). The principal design features include: (a) a gas-tight mist chamber in which nodulated roots can be exposed simultaneously to C(2)H(2) in the gas phase and to a li...

Shoot cultures of Artemisia annua L. were cultivated in three different micropropagation systems: an ultrasonic nutrient mist bioreactor (UNMB), a modified ultrasonic nutrient mist bioreactor (MUNMB) and solid culture in Magenta boxes. The shoots cultivated in the UNMB and MUNMB showed excellent growth. The dry weight increase (35 times) of shoot cultures in the MUNMB was higher than those (25 ...

This paper presents the results and conclusions from experimental investigations concerning filtration properties of nonwovens. The needled nonwovens were made from polyester fibres (PTE) with average fibre diameter 12 micrometres and polypropylene fibres (PP) with average fibre diameter 32 micrometres. Nonwovens were produced out of each of those fibres or out of a mixture of polyester and pol...

Transformed roots are a very promising source of biologically active compounds, but industriallevel production has proved very challenging. Artemisia annua produces artemisinin, a sesquiterpene lactone which is a potent antimalarial. Transformed roots of A. annua have exhibited increased levels of artemisinin when grown in a nutrient mist bioreactor. Additionally, roots showed no evidence of ox...

A new efficient cell was developed to generate a large quantity of aerosol using an ultrasonic nebulizer. The currently used conventional pail-type cell cannot generate such a large quantity of aerosol because a large portion of the mist is lost by agglomeration and subsequent liquefaction onto the cell wall and liquid surface. The newly developed cell is a chimney-type cell characterized by th...

SUMMARY Several outlier and subgroup identification statistics (OASIS) have been proposed to discover transcriptomic features with outliers or multiple modes in expression that are indicative of distinct biological processes or subgroups. Here, we borrow ideas from the OASIS methods in the bioinformatics and statistics literature to develop the 'most informative spacing test' (MIST) for unsuper...

Data centers store a massive amount of data in a large number of servers built by commodity hardware. To maintain data integrity against server failures, erasure codes have been extensively deployed in modern data centers to provide a higher level of failure tolerance with less storage overhead than replication. Yet, compared to replication, disseminating erasure-coded data from a source server...

BACKGROUND The step test has been used to assess exercise capacity in patients with chronic respiratory disease; however, its use has not been described with regard to patients with bronchiectasis (BCT). OBJECTIVE This study assessed the reliability of the Chester step test (CST) and the modified incremental step test (MIST) and also correlated these tests with pulmonary function, heart rate ...
