Helga Kuhse and Peter Singer recently examined the view expressed by John Lorber that whereas at times it is permissible to allow severely handicapped infants to die, killing them must never be allowed. In attempting to demonstrate the mistaken nature of Lorber's fear that allowing active infanticide would lead us onto a slippery slope Kuhse and Singer make much use of John Harris's paper in th...

Abstract In the present paper, effects of diameter, bed slopes, and roughness on free overfall flow semi-circular channels were investigated experimentally. For this purpose, three models with built installed in a 6m long laboratory flume. These 250 cm had varying diameters 160, 200, mm. Four different slopes (S) used each these (0, 0.004, 0.008, 0.012). slope, sand particle sizes to roughen (1...

in a novel dual bed reactor fischer-tropsch synthesis was studied by using two diffrent cobalt catalysts. an alkali-promoted cobalt catalyst was used in the first bed of a fixed-bed reactor followed by a rutenuim promoted cobalt catalyst in the second bed. the activity, product selectivity and accelerated deactivation of the system were assessed and compared with a conventional single bed react...

One of the significant problems facing water resource engineer is calculating coefficient roughness for subsequent design calculations discharge amount a channel or river. In this study, experiments were conducted in semi-circular, straight to investigate factors affecting bed and flow using Artificial Neural Network (ANN). For purpose, three semi-circular models with free overfall constructed ...

A conceptual model based on the dynamic interaction between fire, fuel bed and surrounding flow to explain non-monotonic or intermittent behaviour of fires is proposed. According model, even in nominally permanent uniform boundary conditions, fire-induced modifies geometry flame its rate spread. After an initial acceleration, there a reduction spread followed by one more cycles growth. Carefull...

Bed rest has been shown to have detrimental effects on structural and functional characteristics of the trunk muscles, possibly affecting trunk and spinal stability. This is especially important in populations such as aging adults with often altered trunk stabilizing functions. This study examined the effects of a fourteen-day bed rest on anticipatory postural adjustments and postural reflex re...

Let X be a norm curve in the SL(2,C)-character variety of a knot exterior M . Let t = ‖β‖/‖α‖ be the ratio of the Culler-Shalen norms of two distinct non-zero classes α, β ∈ H1(∂M,Z). We demonstrate that either X has exactly two associated strict boundary slopes ±t, or else there are strict boundary slopes r1 and r2 with |r1| > t and |r2| < t. As a consequence, we show that there are strict bou...

It has long been known that the radial density profiles of globular cluster systems (GCSs) in elliptical galaxies vary with the total luminosities of their host galaxies. In order to elucidate the origin of this structural non-homology in GCSs, we numerically investigate the structural properties of GCSs in elliptical galaxies formed from a sequence of major dissipationless galaxy merging. We f...

This work has developed FEM models of ceramic breeder pebble beds and applied them to two categories of blanket design (edge-on and layer configurations) to predict the thermomechanical behavior of a pebble bed under ITER pulsed operating condition. To explore the pebble bed/structural wall separation phenomenon, a thermomechanical contact is considered using contact elements meshed along pebbl...
