T Slow cooling and long stirring produce particles that are large and spherical, while fast cooling and short stirring produce small, jagged particles that tend to stick together. As a result, the larger particles slide by each other more easily than the smaller ones do, producing a semisolid with less resistance to flow. High-speed videos show that the semisolid advances smoothly and evenly, p...

Entity Resolution concerns identifying co-referent entity pairs across datasets. A typical workflow comprises two steps. In the first step, a blocking method uses a one-many function called a blocking scheme to map entities to blocks. In the second step, entities sharing a block are paired and compared. Current DNF blocking scheme learners (DNFBSLs) apply only to structurally homogeneous tables...

Compliant fish skin is effectively in reducing drag, thus the design and application of compliant bionic materials may be a good choice for drag reduction. Here we consider the drag reduction of compliant bionic materials. First, ZnO and PDMS mesh modified with n-octadecane were prepared, the drag reduction of self-texturing compliant n-octadecane were studied. The results show that the mesh mo...

Serum bactericidal assays (SBAs) for Group B meningococci are considered the methods of choice for the evaluation of functional antimeningococcal antibodies. Many investigators regard SBAs as time- and labor-intensive. Variations in SBA protocols among different laboratories make interpretation of results difficult. Here we describe a fluorescence-based serum bactericidal assay (fSBA) and compa...

A total of 230 cultures of fungi and 43 cultures of bacteria, isolated from such sources as soil, butter, and milk, were screened for their milk-clotting activity. The fungi were cultivated on semisolid media, and the bacteria were grown in milk media in shake culture. Phytic acid, added as calcium phytate, was found to stimulate production of the enzyme in most of the bacterial isolates. Prote...

Plesiomonas shigelloides is the unique member of the Enterobacteriaceae family able to produce polar flagella when grow in liquid medium and lateral flagella when grown in solid or semisolid media. In this study on P. shigelloides 302-73 strain, we found two different gene clusters, one exclusively for the lateral flagella biosynthesis and the other one containing the biosynthetic polar flagell...

To investigate whether mesodermal expansion in the area vasculosa is caused by tension produced by outward migration of cells either in the somatic mesoderm or at the mesodermal edge on an ectodermal substratum, stage 18-20 embryos were transferred to a culture dish. There mesodermal expansion proximal to an arrested edge could be compared with that proximal to a moving edge by measuring the am...

We have developed a rapid method for the isolation of leptospiral chromosomal DNA which yields DNA of a purity suitable for restriction endonuclease analysis. A small volume (15 to 20 ml) of an exponentially growing culture of leptospires yielded 2 to 4 micrograms of chromosomal DNA. In a 1-day protocol, the DNA was isolated, restricted with endonucleases, and fractionated on an agarose gel. Ch...

The objective of this study was to produce an economical, easy to prepare, field-suitable enrichment medium for detection of Campylobacter jejuni in small numbers. A semisolid aerobic enrichment medium was developed. Rates of recovery from inoculated medium, sterile swabs, and mixed cultures of C. jejuni and coliform bacteria were tested.
