The International Time Bureau ( BIH ) began a time scale, T < sub > m </ sub > or AM, in July 1955, using both local caesium clocks and comparisons to distant clocks using the phase of VLF radio signals.

Using the Debye model, the specific heat and entropy of a pure crystal are proportional to T < sup > 3 </ sup >, while the enthalpy and chemical potential are proportional to T < sup > 4 </ sup >.

If ΔS and / or T are small, the condition ΔG < 0 may imply that ΔH < 0, which would indicate an exothermic reaction.

Absolute temperature measurement is uniquely determined by a multiplicative constant which specifies the size of the " degree ", so the ratios of two absolute temperatures, T < sub > 2 </ sub >/ T < sub > 1 </ sub >, are the same in all scales.

APCs then present the fragments to T helper cells ( CD4 < sup >+</ sup >) by the use of class II histocompatibility molecules on their surface.

If activated cytotoxic CD8 < sup >+</ sup > T cells recognize them, the T cells begin to secrete various toxins that cause the lysis or apoptosis of the infected cell.

where k < sub > B </ sub > is Boltzmann's constant, T is the temperature, R is the resistance, and is the bandwidth of the frequency.

auxiliary regression is TR < sup > 2 </ sup >, where T is the sample size and R < sup > 2 </ sup > is the coefficient of determination.

So-called structure zone models were developed to describe the micro structure and ceramics of thin films as a function of the homologous temperature T < sub > h </ sub > that is the ratio of deposition temperature over melting temperature.

According to these models, a necessary ( but not sufficient ) condition for the occurrence of amorphous phases is that T < sub > h </ sub > has to be smaller than 0. 3, that is the deposition temperature must be below 30 % of the melting temperature.

It exists in four major polymorphs: α, β, γ and T. Whereas α, β and T phases are based on B < sub > 12 </ sub > icosahedra, the γ-phase can be described as a rocksalt-type arrangement of the icosahedra and B < sub > 2 </ sub > atomic pairs.

For the case of a non-commutative base ring R and a right module M < sub > R </ sub > and a left module < sub > R </ sub > N, we can define a bilinear map, where T is an abelian group, such that for any n in N, is a group homomorphism, and for any m in M, is a group homomorphism too, and which also satisfies

In an adiabatic irreversible process, dQ = 0 is not equal to TdS ( TdS > 0 ) where Q is thermal energy, T is temperature, and S is entropy.

* BCS theory predicts the dependence of the value of the energy gap E at temperature T on the critical temperature T < sub > c </ sub >.

The questions range from counting ( e. g., the number of graphs on n vertices with k edges ) to structural ( e. g., which graphs contain Hamiltonian cycles ) to algebraic questions ( e. g., given a graph G and two numbers x and y, does the Tutte polynomial T < sub > G </ sub >( x, y ) have a combinatorial interpretation ?).

T denotes the tube axis, and a < sub > 1 </ sub > and a < sub > 2 </ sub > are the unit vectors of graphene in real space.

* Let Q be a set enclosed between two step regions S and T. A step region is formed from a finite union of adjacent rectangles resting on a common base, i. e. S ⊆ Q ⊆ T. If there is a unique number c such that a ( S ) ≤ c ≤ a ( T ) for all such step regions S and T, then a ( Q )

AIX / 370 was IBM's third attempt to offer Unix-like functionality for their mainframe line, specifically the System / 370 ( the prior versions were a TSS / 370 based Unix system developed jointly with AT & T c. 1980, and VM / IX a VM / 370 based system developed jointly with Interactive Systems Corporation c. 1984 ).

Diagram of forces acting on a segment of a catenary from c to r. The forces are the tension T < sub > 0 </ sub > at c, the tension T at r, and the weight of the chain ( 0, − λgs ).

The tension at c is tangent to the curve at c and is therefore horizontal, and it pulls the section to the left so it may be written (− T < sub > 0 </ sub >, 0 ) where T < sub > 0 </ sub > is the magnitude of the force.

Assuming that the strength of the cable is proportional to its density per unit length, the weight, w, per unit length of the chain can be written T / c, where c is constant, and the analysis for nonuniform chains can be applied.

With the reduced state variables, i. e. V < sub > r </ sub >= V < sub > m </ sub >/ V < sub > c </ sub >, P < sub > r </ sub >= P / P < sub > c </ sub > and T < sub > r </ sub >= T / T < sub > c </ sub >, the reduced form of the Van der Waals equation can be formulated:

The lines are asymmetric and over the range of field Af gauss and temperature Af the asymmetry increases with increasing Af and decreasing T.

We are trying to study a linear operator T on the finite-dimensional space V, by decomposing T into a direct sum of operators which are in some sense elementary.

If we try to study T using characteristic values, we are confronted with two problems.

If ( remember this is an assumption ) the minimal polynomial for T decomposes Af where Af are distinct elements of F, then we shall show that the space V is the direct sum of the null spaces of Af.

Let p be the minimal polynomial for T, Af, where the Af, are distinct irreducible monic polynomials over F and the Af are positive integers.

It is certainly clear that the subspaces Af are invariant under T.

If Af are the projections associated with the primary decomposition of T, then each Af is a polynomial in T, and accordingly if a linear operator U commutes with T then U commutes with each of the Af, i.e., each subspace Af is invariant under U.

The diagonalizable operator D and the nilpotent operator N are uniquely determined by ( A ) and ( B ) and each of them is a polynomial in T.

We have just observed that we can write Af where D is diagonalizable and N is nilpotent, and where D and N not only commute but are polynomials in T.

These operators D and N are unique and each is a polynomial in T.

If T is a linear operator on an arbitrary vector space and if there is a monic polynomial P such that Af, then parts ( A ) and ( B ) of Theorem 12 are valid for T with the proof which we gave.

These are real analytic periodic functions with period T.

( C ) Af cuts across C and there are two ordinary intersections for every T in Af.

First, for any value of T for which all values of f{t} are ordinary points the number of values of f{t} must be odd.

* If S and T are in M then so are S ∪ T and S ∩ T, and also a ( S ∪ T )

According to sociologist James T. Richardson, some of the concepts of brainwashing have spread to other fields and are applied " with some success " in contexts unrelated to the earlier cult controversies, such as custody battles and child sexual abuse cases, " where one parent is accused of brainwashing the child to reject the other parent, and in child sex abuse cases where one parent is accused of brainwashing the child to make sex abuse accusations against the other parent ".

D., is the President Emeritus of the non-profit Beck Institute for Cognitive Therapy and Research, and University Professor in the Department of Psychiatry at the University of Pennsylvania and the director of the Psychopathology Research Unit ( PRU ), which is the parent organization of the Center for the Treatment and Prevention of Suicide.

In 2006, the company's direct parent became AT & T Teleholdings, originally Ameritech, upon an internal reorganization at AT & T.

Its former direct parent, Pacific Telesis Group, was legally merged into AT & T Teleholdings.
