We describe a certain category of Ind-towers into which the Pro category of towers of simplicial sets embeds, and in which all colimits (rather than just the finite ones) may be constructed explicitly.

We give explicit equations for the simplest towers of Drinfeld modular curves over any finite field, and observe that they coincide with the asymptotically optimal towers of curves constructed by Garcia and Stichtenoth.

The nondestructive techniques are applied to identify important data from the internal process of distillation towers, process towers, pressure vessels and etc. In recent, the gamma-ray scanning techniques as diagnostic tools for scanning of tray columns, packed columns, storage tanks, level measurement and density measurement of containing materials has been used widely. This paper has tried t...

OBJECTIVE To study the source of non-outbreak legionnaires' disease, particularly the role of cooling towers, by comparing the locations of patients' homes in relation to the location of cooling towers. DESIGN Retrospective, descriptive study of a case series of patients with legionnaires' disease ill between 1978 and 1986 and, for comparison, a case series of patients with lung cancer. A pro...

Objective: To determine whether there is an increased cancer incidence and mortality in populations exposed to radiofrequency radiations from TV towers. Design: An ecological study comparing cancer incidence and mortality, 1972-1990, in nine municipalities, three of which surround the TV towers and six of which are further away from the towers. (TV radiofrequency radiation decreases with the sq...

In the Twin Towers of Hanoi version of the well known Towers of Hanoi Problem there are two coupled sets of pegs. In each move, one chooses a pair of pegs in one of the sets and performs the only possible legal transfer of a disk between the chosen pegs (the smallest disk from one of the pegs is moved to the other peg), but also, simultaneously, between the corresponding pair of pegs in the cou...

Executive dysfunction (ED) is a characteristic of Huntington disease (HD), but its severity and progression is less understood in the prodromal phase, e.g., before gross motor abnormalities. We examined planning and problem-solving abilities using the Towers Task in HD mutation-positive individuals without motor symptoms (n = 781) and controls (n = 212). Participants with greater disease progre...

We consider a set of static towers with communication capabilities, but not within range of each other due to distance and obstacles. The goal is to achieve connectivity among the towers through a set of robots positioned in a way to act as gateways among the towers. The autonomous mobile robots are initially randomly deployed without necessarily being within range of each other, nor of the st...

Packed towers are widely used for distillation processes due to their higher separation efficiency and capacity in comparison to tray towers. The separation efficiency of the tower strongly depends on the liquid flow behaviour inside the packing, which becomes more complex with the appearance of a second liquid phase. Such flow behaviour can be observed in the three-phase distillation process i...

Modular towers, a notion due to M. Fried, are towers of Hurwitz spaces, with levels corresponding to the characteristic quotients of the p-universal Frattini cover of a fixed finite group G (with p a prime divisor of |G|). The tower of modular curves X1(pn) (n>0) is the original example: the group G is then the dihedral group Dp. There are diophantine conjectures on modular towers, inspired by ...
