Surf Clam. Lamin assembly in clam male pronuclei occurs almost invariably in extracts made from 65-min-activated eggs (Longo et ai, 1994). For chromatin decondensation and nuclear envelope assembly, no exogenous nucleotides are required. These are presumably supplied by the cytoplasmic extract. Approximately half of the decondensed sperm nuclei in unactivated or 15-min-activated extracts assemble variable deposits of lamin. 

The study of lamin assembly by the microinjection of fluorescently labeled lamins has the advantage that controlled amounts of renatured protein can be injected, and that the manipulated cells can be continuously observed. The formation of heterodimeric complexes between microinjected 5-IAF-labeled lamins and the endogenous lamins can be largely excluded because the fluorescently labeled lamins are mainly in the form of homodimers assembled during dialysis. Comparison of our microinjection data with results obtained by transfection experiments demonstrates that the mutant phenotype can be obscured in transfected cells by overexpression and/or the formation of heterooligomeric complexes of mutant molecules with wild-type lamins of the transfected cells (Schmidt and Krohne, 1995). Therefore we believe that transfection experiments performed with cDNAs coding for mutated nuclear proteins should eventually be controlled by the microinjection of fluorescently labeled protein.

This is a special type of PPE that has been used by riot police officers to protect limbs from thrown objects in riot situations, and they are basically panels made from lightweight and energy-absorbent materials. The typical material is a laminated assembly of a hard plastic shell and polyurethane foam. The requirements for limb protectors include energy absorption and reflection, light weight and wearing comfort, and they must not hinder the wearers mobility. There has been work attempting to replace the foam with three-dimensional (3D) textiles for this purpose (Chen et al., 2008). 

Although common lap shear specimens supply excellent comparative data for different adhesives and substrate materials, they are relatively small and do not simulate the conditions in large adhesively bonded structures. Hart-Smith has considered the differences between laboratory test specimens and actual bonded structures. ASTM D3165-73 addresses this problem by using samples which are part of actual laminated assemblies. This test technique can be used as a quality control tool during bonding operations. Metal substrates are used primarily but plastic substrates can also be used.

In use Cyanabond Textile Adhesives, lami-nant fabrics, and foam must be completely dried and the laminated assembly then heated to 220°F for 5-10 sec for long term diy cleaning performance, or to 260°F for 15-30 sec for long term washability.
