Diphtheria toxoid is also available combined with tetanus toxoid and pertussis vaccine (DPT), combined with tetanus toxoid alone (DT), and combined with tetanus toxoid for adults (Td).
If there are n free particles of charge q per unit volume with average velocity v and the cross-sectional area of the wire is A, the current i, in elementary calculus notation, is where dQ is the amount of charge that crosses the plane in a time interval dt.
For a temperature change at constant volume, dV = 0 and, by definition of heat capacity, d′QV = CV dT.
In other words, c is the constant of proportionality relating the heat absorbed (d′Q) to the temperature change (dT) according to d′Q = nc dT, where n is the number of moles.
Kilwardby argues that time and motion are exceptions to the rule according to which the parts of composite things must exist simultaneously; instead, he claims, that they are composite transient things, and the parts of time are successive (DT 7 9).
Time is, therefore, the measure not of any specific motion but the measure of motion (DT 42) defined by an instant before and an instant after.
Time is the measure of continuous motion, and the instant is the measure of one of the moments of that continuous alteration (DT 94 95).
One of the questions Kilwardby addresses in his treatise On time (De tempore)—written most probably after DOS is whether time, as the measure of motion, is defined in relation to the diurnal motion (DT 35), a view identified with Averroes.
In like manner, we find Averroes' commenting too on texts suggesting that God has a place (or, relatedly, that He has a body)—including the Quranic description of "God's directing Himself [2 29] and the Tradition about His descent"[30] as texts which have a surface meaning which "is obligatory for those adept in demonstration" to interpret allegorically (DT, B 19).
This equation is derived from the basic relation, \((S - \sigma) \times dt = d\sigma\) (SW IV: 339); Boudewijnse, et al. 1999, present it as: \(d\sigma/dt = (S - \sigma)\).
Time is the number of motion because number is the appropriate name for that measure.[31] We determine time by measuring motion according to fixed measures (days, hours, and so on) (DT 77).
