A method of sending data stored in a database from a sender to arecipient, which are mobile phone users, in relationship with a manager
that defines a managing software application, wherein database and the
manager are in connection with a website, involves entering into a
connection between the sender and the manager. The sender enters into
the connection with the manager and provides sender identification to
the manager. Further, the method involves transferring an identifier tothe manager, wherein the sender transfers the identifier that comprises
at least a recipient's mobile phone number. Further, the method involves
associating an e-mail address or a URL address with the identifier by
the manager.

The focus of our study is on the efficiency of the mixing process instratified shear layers. Certain areas of the oceans including theequatorial Pacific are known to be largely subjected to shear mixing. We
investigate the transition process through which a two dimensional
KelvinHelmhlotz (KH) instability becomes turbulent. KH billows are known
to undergo merging processes. The braid region of the primary KH wave isalso susceptible to a secondary shear instability which can happen
before, during, or after the merging process. The KH billows are also
known to be susceptible to three dimensional convective instabilities
occurring in the outer regions of their billows in which isopycnals
overturn which provides a fast route to turbulent collapse. Occurrence

of the latter instability may eliminate the possibility of the merging
and secondary shear instabilities by quickly destroying the laminarstructure of the two dimensional billow dominated flow. We investigate
the possibility of occurrence of these three instabilities in the
Reynolds and Prandtl (Re-Pr) number space using a theoretical approach.
A map is provided which determines the dominant instability in different
zones of Re-Pr space and identifies the regions of possible coexistenceof multiple instabilities. The map is developed on a theoretical basis
and is tested against high resolution two and three dimensional direct
numerical simulations (DNS). As each of the instabilities have their
specific implications on the mixing efficiency, the map allows
identification of the appropriate value for the mixing efficiency basedon the ambient physical properties of the flow. It also enables aprediction to be made on a priori grounds of the structures that will
characterize the turbulent flow once transition has occurred.

A multi-layer ozone(O<sub>3</sub>) dry deposition model has been
implemented into SOSAA (a model to Simulate the concentrations ofOrganic vapours, Sulphuric Acid and Aerosols) to improve therepresentation of O<sub>3</sub> concentration and flux within and above
the forest canopy in the planetary boundary layer. We aim to predict theO<sub>3</sub> uptake by a boreal forest canopy under varying
environmental conditions and analyse the influence of different factors
on total O<sub>3</sub> uptake by the canopy as well as the vertical
distribution of deposition sinks inside the canopy. The newly
implemented dry deposition model was validated by an extensive
comparison of simulated and observed O<sub>3</sub> turbulent fluxes andconcentration profiles within and above the boreal forest canopy at
SMEARII (Station to Measure Ecosystem-Atmosphere Relations II) in
Hyytiaelae, Finland, in August2010. In this model, the fraction of wet
surface on vegetation leaves was parametrised according to the ambient
relative humidity(RH). Model results showed that when RH was larger than
70% the O<sub>3</sub> uptake onto wet skin contributed ~ 51% to thetotal deposition during nighttime and ~ 19% during daytime. The overall
contribution of soil uptake was estimated about 36%. The contribution of
sub-canopy deposition below 4.2m was modelled to be ~ 38% of the total
O<sub>3</sub> deposition during daytime, which was similar to thecontribution reported in previous studies. The chemical contribution to
O<sub>3</sub> removal was evaluated directly in the model simulations.
According to the simulated averaged diurnal cycle the net chemical
production of O<sub>3</sub> compensated up to ~ 4% of dry deposition
loss from about 06:00to 15:00LT. During nighttime, the net chemical lossof O<sub>3</sub> further enhanced removal by dry deposition by a maximum~ 9%. Thus the results indicated an overall relatively small
