The ultrastructure of the apical zone of lactating rat mammary epithelial cells was studied with emphasis on vesicle coat structures. Typical 40-60 nm ID "coated vesicles" were abundant, frequently associated with the internal filamentous plasma membrane coat or in direct continuity with secretory vesicles (SV) or plasma membrane proper. Bristle coats partially or totally covered membranes of s...

Alterations in the structure of the tobacco mosaic virus (TMV) coat protein affect the elicitation of the N' gene hypersensitive response (HR) in Nicotiana sylvestris. To investigate this structure-function relationship, amino acid substitutions with predicted structural effects were created throughout the known structure of the TMV coat protein. Substitutions that resulted in the elicitation o...

OBJECTIVES To examine the hypothesis that the use of a wash product formulated for newborn (<1 month of age) bathing is not inferior (no worse) to bathing with water only. DESIGN Assessor-blinded, randomized, controlled, noninferiority trial. SETTING A teaching hospital in the Northwest of England and in participants' homes. PARTICIPANTS Three-hundred-and-seven healthy, term infants recru...

Most of distilleries in India use biomethanation process to treat the spent wash generated during the alcohol process, to ensure the effective treatment all distillery industries follow 13 fold dilutions due to which tremendous amount of spent wash is generated. 8 -15 l of spent wash was generated during 1 l of alcohol, thus distillery industries consume more water and produce waste water on a ...

The effects of laundering and time of exposure on the insecticidal activity of military uniform fabric impregnated with permethrin at 0.125 mg active ingredient (AI)/cm2 are reported from susceptibility tests with laboratory-reared mosquitoes, Culex pipiens, and sand flies, Phlebotomus papatasi. Knockdown/mortality resulting from exposure of groups of female insects for periods of 1, 3, 5, 7, a...

The translocation of Escherichia coli O157:H7 as well as the impact of water washing and partial or complete surface trimming as possible pathogen reduction strategies were evaluated for vacuum-packaged beef subprimals destined for nonintact use. Cap-on and cap-off beef top sirloin butts were inoculated with two levels of E. coli O157:H7: a high-inoculum level of approximately 10(4) CFU/cm(2) a...

When drilling an oil well, the well is lined by sinking a steel casing, or liner, into the drilling mud (see Figure 1). The inside of the liner forms a central pipe, and leaves an annular gap between the outside of the liner and the surrounding rock. The inside and outside of the liner are initially filled with drilling mud, which is displaced by pumping a sequence of fluids down inside the lin...

Harborage of Escherichia coli O157:H7 and Salmonella on animal hides at slaughter is the main source of beef carcass contamination during processing. Given this finding, interventions have been designed and implemented to target the hides of cattle following entry into beef processing plants. Previous interventions targeting hides have not been suitable for all beef processing plants because of...

Thermal barrier coating (TBC) systems are known to be extremely sensitive the applied thermo-mechanical loading in terms of both microstructure evolution and subsequent damage, leading final failure by ceramic top-coat layer spallation. The analysis relationship between mechanical behavior is limited scatter experimental results. Based on a typical TBC system for columnar top-coat, this study f...
