Shedding of Multiple Sessile Droplets
… the droplets adhesion force. Presence of other sessile droplets, in proximity, changes the drag force, so the minimum airflow velocity required to shed the droplets (Ucr) can vary. In this thesis, an experimental study on shedding of the multiple sessile droplets was performed on both …

On the evaporation of sessile droplets
In this thesis the evolution of sessile droplets in different modes of evaporation and their lifetimes are investigated. The thesis focuses on situations in which the diffusion of vapour into the surrounding atmosphere is the rate-limiting mechanism of evaporation. First, we describe the evolution …

Influence of forced convection on sessile droplet evaporation
… systems can leverage the evaporation of sessile droplets to implement this effect for different cooling applications. In the case of human perspiration, droplet evaporation typically occurs under exposure to moving air, or forced convection. However, current approaches to understanding …

A Molecular Dynamics Study of Sessile Droplet Evaporation
… are used to test the existing theories on sessile droplet evaporation.

INTERFACIAL TENSION MEASUREMENT BY SESSILE DROP USING DIGITAL IMAGE PROCESSING
… spinning drop technique is very popular but the sessile drop method offers the advantage that it is a static system. Most previous systems required a photograph to be taken and analysis was limited to key coordinates along the profile. A sessile drop system has been designed which allows drops or …

Sessile droplets of salt solutions on inert and metallic surfaces
… we investigate the evaporation behaviour of sessile droplets of aqueous saline solutions on planar inert and metallic surfaces and characterise the corrosion phenomenon for iron surfaces. First we study the evaporation behaviour of sessile salty droplets on inert surfaces for a wide range of …

Electrohydrodynamic Manipulation of Sessile Droplets by the In-Plane Electric Fields
… (with DC voltages in the kV-range applied) on sessile droplets of multiple pure liquids, solvents, colloidal suspensions (with particles and pigments) and conducting polymers commonly used in painting and coating processes. This fundamental research aims at understanding the principles and …

Sessile Droplet Microfluidic Platforms for Improvements in Mass Spectrometry Sample Preparation
Sessile droplet microfluidic devices (SDMF) allow for small, uniform liquid volumes to be arrayed, addressed, and manipulated independently. SDMF platforms diverge from typical flow-based lab-on-a-chip (LOC) devices while maintaining their advantages (low sample consumption, high throughput, and …

Sessile Invertebrate Colonization on Rocky Outcrops at Gray's Reef National Marine Sanctuary
<p>Documenting patterns of sessile invertebrate community development is important for predicting recovery patterns after disturbance and designing effective marine reserves. In the South Atlantic Bight, invertebrate assemblages can differ significantly from one rocky outcrop to another, but the …

Interactions Between the Odorous House Ant (Tapinoma sessile) and RNA Viruses: a Multi-Faceted Approach
The odorous house ant, Tapinoma sessile, is a widespread, common pest in North American residential areas, yet the understanding of how viral pathogens shape its behavior, management, and interactions with other insects remains limited. Over the course of my thesis, I characterized four novel …

Foraging Activity and Food Preferences of the Odorous House Ant (Tapinoma sessile Say) (Hymenoptera: Formicidae)
… food preferences of odorous house ants (Tapinoma sessile (SAY)) were investigated in both the field and laboratory. Foraging activity was examined in the field from April to September 2001 by attracting T. sessile to feeding stations containing a 20% sucrose solution. Ant foraging activity was …

Analysis of heat transfer and fluid flow in an evaporating sessile droplet for evaporative cooling applications
… miniaturized technology. The evaporation of the sessile liquid droplet facilitates the phase change of that liquid and provides cooling to the system, because a large amount of latent heat is required to change the phase. Evaporation takes place at the liquid-vapour interface, so to enhance the …

Analysis and feasibility of an evaporative cooling system with sessile droplet evaporation to provide cooling for microprocessors
… Processor using diffusion based evaporation of sessile droplets. An analytical model is developed to determine the capacity of a single layer of droplets to provide sufficient cooling. It is found that a single layer can provide sufficient cooling for the processors with tiny droplets. A …

Sessile serrated lesions in focus: Examining temporal trends, patient risk factors, and the role of the endoscopist in lesion detection
… research in prognostication. A specific subtype, sessile serrated lesions (SSLs), are of particular interest, as they are the most prevalent premalignant subtype and are over-represented in cases of interval cancers. Accurate identification and risk assessment remains a challenge owing to variable …

Prevalence and impacts of ants colonizing active bird nests in Illinois
… nests, and for three of these species (Tapinoma sessile, Temnothorax curvispinosus, and Crematogaster cerasi) there was evidence that at least part of their colonies inhabited the nest. Tapioma sessile was the most common species and maintained the largest colonies in nest material. I found that …

Biooxidation kinetics of Leptospirillum Ferriphilum attached to a defined solid substrate
… changing over time and are dominated by sessile microorganisms (attached microorganisms to the surface of a solid). The heap bioleaching system is therefore highly complex compared to the stirred tank-type systems. Microbial growth in bioleaching systems significantly influence the …

Habitat association and distribution of Nauticaris marionis at the Sub-Antarctic Prince Edward Islands
… the caridean shrimp Nauticaris marionis and sessile epibenthic assemblages and substratum types of the Sub-Antarctic Prince Edward Islands were investigated. Twenty five stations, varying in substratum type, depth and location on the shelf and slope around the islands were sampled …
