Reliability of drop size from multi-dose eye drop bottles: is it cause for concern?

Preferences and ease of use of preservative-free IOP-lowering eye drop containers: A comparison of two multi-dose bottles

Glaucoma is the leading cause of permanent blindness worldwide [1]. Although disease progression can be delayed with intraocular pressure (IOP)-lowering agents [2], patient adherence still remains a barrier to effective treatment [3-5]. Patient adherence is multifactorial, with tolerability and convenience factors both playing an important role [2,6]. To address the tolerability issues associat...

Hypermodelling for Drag and Drop Concern Queries

Imagine a developer, who wants to alter the service layer of an application. Even though the principle of separation of concerns is widespread not all elements belonging to the service layer are clearly separated. Thus, a programmer faces the challenge to manually collect all classes that belong to the service layer. In this paper we present the Hypermodelling approach that can be used to query...

Drop retention force as a function of drop size.

The force, f, required to slide a drop past a surface is often considered in the literature as linear with the drop width, w, so that f/w = const. Furthermore, according to the Dussan equation for the case that the advancing and receding contact angles are constant with drop size, one can further simplify the above proportionality to f/V(1/3) = const where V is the drop volume. We show, however...

Mean Drop Size and Drop Size Distribution in a Hanson Mixer-Settler Extraction Column

Small-Scale Drop-Size Variability: Empirical Models for Drop-Size-Dependent Clustering in Clouds

By analyzing aircraft measurements of individual drop sizes in clouds, it has been shown in a companion paper that the probability of finding a drop of radius r at a linear scale l decreases as l, where 0 D(r) 1. This paper shows striking examples of the spatial distribution of large cloud drops using models that simulate the observed power laws. In contrast to currently used models that assume...
