We consider the problem of a Boussinesq fluid forced by applying both non-uniform temperature and stress at the top surface. On the other boundaries the conditions are thermally insulating and either no-slip or stress-free. The interesting case is when the direction of the steady applied surface stress opposes the sense of the buoyancy driven flow. We obtain two-dimensional numerical solutions ...

The writers of this paper see the current highway design standards as a two-dimensional projection which the horizontal and vertical alignments are treated separately. A model developed in this paper considers and study the sight distance as a three-dimensional alignment on the design requirements. The paper examines the required minimum radius of a horizontal curve combined with a crest or sag...

. Abstract. Horizontal mixing in the upper hypolimnion of lues far from the boundaries was studied in lake basins with surface areas between 5 and 220 km2 by observing the growth of the concentration distribution of the fluorescent dye sodium fluorescein (uranin). In each of the eight experiments, between 0.2 and 2 kg of uranin was instantaneously released into the lake in the appropriate depth...

Aspect-Oriented Programming (AOP) is an emerging paradigm to modularize crosscutting concerns. A series of guidelines to refactor a software system into a common core and a set of variable functionalities have become known as Horizontal Decomposition (HD). In this paper we apply the HD principles to the Prevayler main memory database management system. The objective is to evaluate and refine th...

We read with interest the article entitled “Volumetric thin-section CT: evaluation of pulmonary interlobar fissures” by Guan et al. (1) in the Nov-Dec 2015 issue of Diagnostic and Interventional Radiology. The authors gave detailed information about interlobar fissures, their incompleteness, relationship to vascular structures, CT appearance, and defect location. The interlobar fissures and the...

I review aspects of the evolution of horizontal branch (HB) stars. The defining characteristic of this, the core He-burning phase of evolution for M < Mflash ∼ 2.2M⊙, is a spread in observed colour amongst HB stars within the (almost) chemically homogeneous, isochronous populations found in Galactic globular clusters. The inference is that the stars within a given cluster must have undergone va...

A challenging question is how XML can be used to support distributed databases. This leads to the problem of how to obtain a suitable, cost-efficient distribution design for XML documents. In this paper we sketch a heuristic approach to minimise query costs for the case of horizontal fragmentation. The approach is based on a cost model that takes the complex structure of queries on XML document...

We consider an SU(2)L × SU(2)R × U(1)B−L × SU(3) L H gauge model with natural flavour conservation in the Higgs sector, in which CP-violation occurs due to the horizontal interactions only. We calculate the CP-violating observables ǫ and ǫ′ of the neutral kaon sector and dn, the electric dipole moment of the neutron. The regions of the parameter space which yield a value of ǫ that is in agreeme...

Horizontal or lateral violence is considered an act of aggression among nursing professionals. Horizontal violence creates a negative work environment impairing teamwork and compromising patient care. The effects of horizontal violence and strategies for prevention and management are addressed.
