It has relatively high compressive strength, of about 170 MPa ( 1800 kgf / cm² ) but poor tensile strength of 104 – 121 MPa and very low shear stress strength ( 51. 6 MPa ), meaning it resists pushing forces well, but not pulling or torsional forces.

** the former yat alternates between " ya " and " e ": it is pronounced " ya " if it is under stress and the next syllable does not contain a front vowel ( e or i ) – e. g. мляко ( mlyàko ), хляб ( hlyab ), and " e " otherwise – e. g. млекар ( mlekàr ) – milkman, хлебар ( hlebàr ) – baker.

In children or adolescents, CBT is an effective part of treatment plans for anxiety disorders, body dysmorphic disorder, depression and suicidality, eating disorders and obesity, obsessive – compulsive disorder, and posttraumatic stress disorder, as well as tic disorders, trichotillomania, and other repetitive behavior disorders.

In the United Kingdom, the National Institute for Health and Clinical Excellence ( NICE ) recommends CBT in the treatment plans for a number of mental health difficulties, including posttraumatic stress disorder, obsessive – compulsive disorder ( OCD ), bulimia nervosa, and clinical depression.

In children or adolescents, CBT is an effective part of treatment plans for anxiety disorders, body dysmorphic disorder, depression and suicidality, eating disorders and obesity, obsessive – compulsive disorder, and posttraumatic stress disorder, as well as tic disorders, trichotillomania, and other repetitive behavior disorders.

Since there is no evidence that late Maastrichtian nonavian dinosaurs could burrow, swim or dive, they were unable to shelter themselves from the worst parts of any environmental stress that occurred at the K – T boundary.

In special relativity, mass turns out to be part of a more general quantity called the energy – momentum tensor, which includes both energy and momentum densities as well as stress ( that is, pressure and shear ).

Many scholars have argued that Matthew is simply an expanded version of Mark, but it is also a creative reinterpretation of the source, stressing Jesus ' teachings as much as his acts, and making subtle changes in order to stress Jesus ' divine nature – Mark's " young man " who appears at Jesus ' tomb, for example, becomes a radiant angel in Matthew.

) must be adapted to high salt levels, whereas in the compatible solute adaptation little or no adjustment is required to intracellular macromolecules – in fact, the compatible solutes often act as more general stress protectants as well as just osmoprotectants.

Meanwhile, the investigation into the British Embassy leak was still ongoing, and the stress of it was exacerbated by the arrival in Washington, in October 1950, of Guy Burgess – Philby's unstable, dangerously alcoholic, and flamboyantly homosexual Cambridge colleague and fellow Soviet spy.

A common assumption is that disorders may have resulted from genetic and developmental vulnerabilities, exposed by stress in life ( for example in a diathesis – stress model ), although there are various views on what causes differences between individuals.

Recent extreme droughts ( 2000 – 2007 ) have put significant stress on river red gum forests, with mounting concern over their long term survival.

While phonemes are normally conceived of as abstractions of discrete segmental speech sounds ( vowels and consonants ), there are other features of pronunciation – principally tone and stress – which in some languages can change the meaning of words in the way that phoneme contrasts do, and are consequently called phonemic features of those languages.

A good example of this is when a body which is not quite an elastic solid ( i. e. an inelastic solid ) does not maintain a constant deformation under constant stress, but rather continues to deform with time – or " creeps " under the same stress at constant temperature.

The involved are addressed to another structure called the CUMP – Cellule d ' urgence médico-psychologique ( medical-psychological urgency cell ); this is a resting zone, with food and possibly temporary lodging, and a psychologist to take care of the brief reactive psychosis and avoid post-traumatic stress disorder.

During the harsh winter of 1798 – 99, Wordsworth lived with Dorothy in Goslar, and, despite extreme stress and loneliness, he began work on an autobiographical piece later titled The Prelude.

In 1913 – 14 Léger produced a series entitled Contrasts of Forms, giving a similar stress to color, line and form.

It is true that certain experimentally verified quantum phenomena, such as the Casimir effect, when described in the context of the quantum field theories, lead to stress – energy tensors that also violate the energy conditions, such as negative mass-energy, and thus one can hope that Alcubierre-type warp drives can be physically realized by clever engineering taking advantage of such quantum effects.

Performance testing can be combined with stress testing, in order to see what happens when an acceptable load is exceeded – does the system crash?

Concepts such as the stress concentration factor and the strain energy release rate can be used to predict failure.

Once the fault has locked, continued relative motion between the plates leads to increasing stress and therefore, stored strain energy in the volume around the fault surface.

This continues until the stress has risen sufficiently to break through the asperity, suddenly allowing sliding over the locked portion of the fault, releasing the stored energy.

This is so because the energy released in an earthquake, and thus its magnitude, is proportional to the area of the fault that ruptures < ref > and the stress drop.

This difference in stress regime in the three faulting environments can contribute to differences in stress drop during faulting, which contributes to differences in the radiated energy, regardless of fault dimensions.

Later he developed the idea of two " reservoirs " of stress resistance, or alternatively stress energy.

Similarly, a fluid while flowing under constant stress may show some elastic properties as well, such as storing some of the energy input instead of dissipating it all as heat and random thermal motion of its molecular constituents or having some recovery of strains after stresses are removed, although it may never recover all of its deformation upon removal of the initial applied stress.

When such bodies are subjected to a sinusoidally oscillating stress, the strain is neither exactly in phase with the stress ( as it would be for a perfectly elastic solid ) nor 90 degrees out of phase ( as it would be for a perfectly viscous liquid ) but rather exhibits a strain that lags the stress at a value between zero and 90 degrees: i. e., Some of the energy is stored and recovered in each cycle, and some is dissipated as heat.

Regular, brisk cycling or walking can improve confidence, stamina, energy, weight control, life expectancy and reduce stress.

The resultant fate depends on whether the critical defect size was exceeded which in turn depends on the applied field, local mechanical stress and bilayer edge energy.

They have the advantage of yielding more energy than obligate anaerobes, but face high levels of oxidative stress .< ref >" Obligate aerobe-definition from Biology-Online. org.

Based on Ginzburg – Landau theory, the free energy of a ferroelectric material, in the absence of an electric field and applied stress may be written as a Taylor expansion in terms of the order parameter, P. If a sixth order expansion is used ( i. e. 8th order and higher terms truncated ), the free energy is given by:

One likelihood is that stress diverts energy away from the immune system, thereby stress promotes Helicobacter pylori infection in the body.

It can be caused by chemical reactions, electrical energy, subatomic motions, or stress on a crystal.

For a Newtonian fluid, the deviatoric stress tensor is related to the velocity by

sometimes called the Maxwell stress tensor.

By eliminating ρ and J, using Maxwell's equations, and manipulating using the theorems of vector calculus, this form of the equation can be used to derive the Maxwell stress tensor σ, in turn this can be combined with the Poynting vector S to obtain the electromagnetic stress-energy tensor T used in general relativity.

The quantity is called the Maxwell stress tensor, defined as

The electromagnetic stress tensor depends on the properties of the media.

Stress ( mechanics ) | The stress tensor, a second-order tensor.

For example, the stress tensor T takes a direction v as input and produces the stress T < sup >( v )</ sup > on the surface normal to this vector as output and so expresses a relationship between these two vectors.

where v is the flow velocity, ρ is the fluid density, p is the pressure, is the ( deviatoric ) stress tensor, and f represents body forces ( per unit volume ) acting on the fluid and ∇ is the del operator.

The stress – energy tensor ( sometimes stress – energy – momentum tensor ) is a tensor quantity in physics that describes the density and flux of energy and momentum in spacetime, generalizing the stress tensor of Newtonian physics.
