Spontaneous subcapsular renal haematoma is a rare condition caused by bleeding into the subcapsular or perinephric space in the absence of trauma, bleeding diathesis or anticoagulation. If the contralateral kidney is normal, radical nephrectomy is recommended due to a high incidence of small occult tumours.

AbstractIt is shown that the concepts of normal radical as introduced by Jaegermann [2] and of invariant radical as introduced by Anderson, Divinsky and Sulinski [1] are equivalent.

AbstractA variant of Kurosh-Amitsur radical theory is developed for algebras with a collection of (finitary) operations ω, all of which are idempotent, that is satisfy the condition ω(x, x,…,x) =x. In such algebras, all classes of any congruence are subalgebras. In place of a largest normal radical subobject, a largest congruence with radical congruence classes is considered. In congruence-permutable varieties the parallels with conventional radical theory are most striking.

The polymerization of methyl methacrylate has been studied by the viscosity method (part I, 1948). The reaction is shown to be a normal radical chain process with velocity constants at 0°C given in table 3. It has been found that irradiation of methyl methacrylate by ultra-violet light produces a catalyst, while an inhibitor is formed by a thermal reaction. These facts account for the difficulties experienced by other workers. A reinvestigation of the vapour-phase polymerization shows that they also account for the anomalous polymerization observed by Melville (1937), and attributed by him to a ‘bound-bond’ mechanism. Chain termination in the polymerization of styrene and methyl methacrylate is shown to occur by disproportionation.
