An Experiment of 1, 1, 1-Trichloroethane Vapor Exposure to Mice : Supplementary Report on the Toxicity of 1, 1, 1-Trichloroethane I

Industrial gassing poisonings due to trichlorethylene, perchlorethylene, and 1-1-1 trichloroethane, 1961-80.

During the period 1961-80, 384 cases of industrial gassing poisonings by trichlorethylene, perchlorethylene, and 1-1-1 trichloroethane (methylchloroform) were reported to HM Factory Inspectorate. A study of these data, which have been collated and analysed with particular reference to sex, age, clinical manifestations, and circumstances of the incident, is presented. Possible bias of the data o...

I-1: Spermatogonial Ontogeny in Mice

Background:Spermatogenesis is maintained by a pool of the spermatogonia. The group formed by As, Apr and Aal is known as undifferentiated type a spermatogonia (Aund). The Aal spermatogonia will differentiate, with no mitotic division, to the differentiating type A1 spermatogonia. The type A1 spermatogonia undergo 6 successive mitotic divisions to yield A2, A3, A4, intermediate-type (In), and ty...

Cohomology of aff(1|1) acting on the space of bilinear differential operators on the superspace IR1|1

We consider the aff(1)-module structure on the spaces of bilinear differential operators acting on the spaces of weighted densities. We compute the first differential cohomology of the Lie superalgebra aff(1) with coefficients in space Dλ,ν;µ of bilinear differential operators acting on weighted densities. We study also the super analogue of this problem getting the same results.

Group ${1, -1, i, -i}$ Cordial Labeling of sum of $C_n$ and $K_m$ for some $m$

Let G be a (p,q) graph and A be a group. We denote the order of an element $a in A $ by $o(a).$  Let $ f:V(G)rightarrow A$ be a function. For each edge $uv$ assign the label 1 if $(o(f(u)),o(f(v)))=1 $or $0$ otherwise. $f$ is called a group A Cordial labeling if $|v_f(a)-v_f(b)| leq 1$ and $|e_f(0)- e_f(1)|leq 1$, where $v_f(x)$ and $e_f(n)$ respectively denote the number of vertices labelled w...
