Scanning Electron

The scanning electron microscope (SEM) can be run at television scanning rates and used with a video tape recorder to observe dynamic specimen changes. With a conventional tungsten source, a low noise TV image is obtained with a field of view sufficient to cover the area of the specimen to be recorded. Contrast and resolution considerations have been elucidated and many changing specimens have been studied at TV rates.To extend the work on measuring the magnitude of charge and field distributions of small particles in the SEM, we have investigated their motion and electrostatic interaction at TV rates. Fig. 1 shows a time sequence of polystyrene spheres on a conducting grating surface inclined to the microscope axis. In (la) there are four particles present in the field of view, while in (lb) a fifth particle has moved into view.

This article attempted to trace the existence of Dhâmmong tradition in the following scopes, namely: (1) Madurese perception against Dhâmmong , (2) the function and symbolic meaning of Dhâmmong in human life, and (3) the efforts of the Madurese community to preserve the Dhâmmong tradition. Through a descriptive phenomenological analysis, this study revealed that Dhâmmong is a hereditary tradition carried out by the Madurese community, it is urged by the community’s anxiety caused by the long dry season (némor lanjheng). Dhâmmong functionsas a means for salametan, paying respect for the ancestors, strengthening human relations (silaturrahim ), Bhek Rembhek, and nguri berkah (the fertility of the earth). The offerings and mouth-music by imitating the sounds of animals represent a strong desire and wishof the community for the immediate rainfall that could pour out blessings for the community. Hence, the community’s efforts to preserve Dhâmmong are: (1) introducing and involving the younger generation in the ritual, and (2) setting and changing the time sequence of Dhâmmong implementation from night to daytime.

The Impact

Biosurfactants, are surface active molecules that can be produced by renewable, industrially scalable biologic processes. DAMP4, a designer biosurfactant, enables the modification of interfaces via genetic or chemical fusion to functional moieties. However, bioconjugation of addressable amines introduces heterogeneity that limits the precision of functionalization as well as the resolution of interfacial characterization. Here we designed DAMP4 variants with cysteine point mutations to allow for site-specific bioconjugation. The DAMP4 variants were shown to retain the structural stability and interfacial activity characteristic of the parent molecule, while permitting efficient and specific conjugation of polyethylene glycol (PEG). PEGylation results in a considerable reduction on the interfacial activity of both single and double mutants. Comparison of conjugates with one or two conjugation sites shows that both the number of conjugates as well as the mass of conjugated material impacts the interfacial activity of DAMP4. As a result, the ability of DAMP4 variants with multiple PEG conjugates to impart colloidal stability on peptide-stabilized emulsions is reduced. We suggest that this is due to constraints on the structure of amphiphilic helices at the interface. Specific and efficient bioconjugation permits the exploration and investigation of the interfacial properties of designer protein biosurfactants with molecular precision. Our findings should therefore inform the design and modification of biosurfactants for their increasing use in industrial processes, and nutritional and pharmaceutical formulations.
