This project will develop cloud droplet probes and phase-Doppler anemometry for measuring sizesegregated droplet concentrations at high wind speeds in the ABL. The data will be used for investigating droplet dynamics in the marine atmospheric boundary layer, characterizing the droplet surface flux source function, and determining the effect spray drops have on air-water surface exchange process...

Very often the student in histology, as well as the more advanced worker in this field, finds the subject of fibrillae in cells somewhat difficult and confusing. In spite of the fact that fibrillae have been the subject of investigation for many years, authorities are not agreed concerning the structure or function of these cellular elements, and there are still some who have doubts as to their...

Some interesting properties of protoplasm are revealed when slightly hypertonic solutions of sugars or of electrolytes are applied to Nitella. The chloroplasts contract and the space between them increases and forms a characteristic pattern consisting of clear areas extending lengthwise along the cell and tapering off at both ends. The development of these areas is irreversible from the start. ...

In this paper, we got femtoliter volume droplet by splitting of nanoliter droplet at a T-junction channel, and the volume of the daughter droplet was not limited by the channel size. We use this droplet splitting system to entrap several fluorescent nanospheres, which show great potential to manipulate and observe single nanoparticles independently. The influences of fluid flow rate, channel ge...

Particles adsorbed on the surface of a droplet form three-dimensional packings when the droplet evaporates. We study the final packings when the liquid droplet is attached to a solid substrate. In contrast to a droplet evaporating away from a substrate, here the final packings are highly dependent on both the number of particles and the contact angle between the droplet and the surface. Simple ...

Spontaneous rotation of a droplet induced by the Marangoni flow is analyzed in a two-dimensional system. The droplet with the small particle which supplies a surfactant at the interface is considered. We calculated flow field around the droplet using the Stokes equation and found that advective nonlinearity breaks symmetry for rotation. Theoretical calculation indicates that the droplet spontan...

Perineuronal glial nets in the rat spinal cord were studied. According to the density of the nets and the thickness of the processes which form them, different types of nets were demonstrated. In addition to nets originating from microglial cells, nets formed by smooth protoplasmic astrocytes are also described.

Intramembrane particles in the freeze-fractured faces of erythrocyte membranes from persons with several different types of muscular dystrophy are examined. The density of particles in the protoplasmic face was lower than that of controls, although not at a statistically significant level. No altered pattern of aggregation of these particles was observed.

Molecular dynamics simulations are used to model the evaporation of a Lennard–Jones argon nanodroplet into its own vapor for a wide range of ambient temperatures and ambient pressures. The transitions from i high to low Knudsen number evaporation and ii subcritical to supercritical evaporation are observed. At a low ambient pressure of 0.4 MPa, the initial droplet Knudsen number is 1 and the dr...

Mature white adipocytes contain a characteristic unilocular lipid droplet. However, the molecular mechanisms underlying unilocular lipid droplet formation are poorly understood. We previously showed that Fsp27, an adipocyte-specific lipid droplet-associated protein, promotes lipid droplet growth by initiating lipid exchange and transfer. Here, we identify Perilipin1 (Plin1), another adipocyte-s...
