The influence of the local terrestrial environment on nocturnal atmospheric CO2 measurements at a 329-m television transmitter tower (and a component of a CO2 monitoring network) was estimated with a tracer release experiment and a subsequent simulation of the releases. This was done to characterize the vertical transport of emissions from the surface to the uppermost tower level and how it is ...

On July 9, 2013, an outbreak of Legionnaires' disease (LD) was identified at Long-Term Care Facility A in central Ohio. This article describes the investigation of the outbreak and identification of the outbreak source, a cooling tower using an automated biocide delivery system. In total, 39 outbreak LD cases were identified; among these, six patients died. Water samples from a cooling tower we...

The last decade has seen an unprecedented rise in greenhouse gases in the atmosphere mostly due to anthropogenic activities. In order to cutback on the greenhouse gas emissions we need to calculate accurately the greenhouse gas budget. The paper being reviewed here delineates a fine approach in that direction. The paper describes measurements from an old radio tower in Switzerland. Tall tower m...

We fix a monic polynomial f(x) ∈ Fq[x] over a finite field and consider the Artin-Schreier-Witt tower defined by f(x); this is a tower of curves · · · → Cm → Cm−1 → · · · → C0 = A, with total Galois group Zp. We study the Newton slopes of zeta functions of this tower of curves. This reduces to the study of the Newton slopes of L-functions associated to characters of the Galois group of this tow...

Xi'an Bell Tower (the Bell Tower) is a state-level ancient relic in China. The vibration caused by metro will exert adverse effect on the Bell Tower. This paper aims at presenting 3D-FEM models to predict the peak period velocity (PPV) of rammed earth base when the metro passing through the Bell Tower. The calculation results are compared with those of field test. Both results were found to be ...

The purpose of this paper is to prove the Frame-Stewart algorithm for the generalized Towers of Hanoi problem as well as finding the number of moves required to solve the problem and studying the multitude of optimal solutions. The main idea is to study how to most effectively move away all but the last disc and use the fact that the total number of moves required to solve the problem is twice ...

Combinatorial properties of the multi-peg Tower of Hanoi problem on n discs and p pegs are studied. Top-maps are introduced as maps which reflect topmost discs of regular states. We study these maps from several points of view. We also count the number of edges in graphs of the multi-peg Tower of Hanoi problem and in this way obtain some combinatorial identities.

Recently, there has been increased interest in moving the RF electronics in basestations from the bottom of the tower to the top, yielding improved power efficiencies and reductions in infrastructural costs. Tower-top systems have faced resistance in the past due to such issues as increased weight, size, and poor potential reliability. However, modern advances in reducing the size and complexit...

he present paper deals with the study of static and dynamic analysis of transmission line tower (X type of bracing system). A typical type of transmission line tower carrying 220KV single circuit conductor is chosen as case study existing in bijapur district. The analysis and modeling of tower is carried out using FE based ANSYS software. The model is created in CATIA and then imported to ANSYS...

In order to locate a 150m wind monitoring tower to measure the wind characteristics, we investigated the site near Paradip, Odisha (India) to locate wind tower and collected some wind data to incorporate into the design of tubular steel tower. This paper seeks to understand the design of tubular steel tower and its performance parameter up to 150m height, also it provides the stability analysis...
