Abstract

The forests of North Cachar Hilis and Barail Range of Assam were explored by the author in February, 1971 and a large number of interesting specimens were collected. The present paper covers Dicotyledones, Polypetalae, with 314 species (+ 1 spp & 2 vats) representing 218 genera and distributed over 77 families. The system of Bentham and Hooker with modifications. Made in conformity with modern concepts has been followed. The scientific names of the plant listed in the present work have been corrected as for as possible.

Abstract

The groups of machine building industry in India engaged in the manufacture of specialised and intricate paper and pulp machinery is now in the take off stage. The Government has shown interest in giving licence to a number of companies to take up manufacture of paper and pulp machinery. The machine building industry is, therefore, now in a good position to accept orders for paper and pulp machinery.

Abstract

Hair dye poisoning is not rare but is an emerging poisoning in India. The main component of hair dye causing toxicity is paraphenylenediamine (PPD). Acute poisoning by PPD causes characteristic severe angioedema of the upper airway accompanied by a swollen, dry, hard, and protruding tongue. Systemic intoxication results in multisystem involvement and can cause rhabdomyolysis, acute renal failure (ARF). PPD consumption is an uncommon cause of ARF. There is no specific antidote for PPD and treatment is mainly supportive. We report a case of suicidal ingestion of hair dye that presented with cervicofascial edema and later developed rhabdomyolysis and ARF. Our patient improved with dialysis and symptomatic management.

Abstract

It is shown that if X is a separable Banach Space with the hermitian approximation property, then there exists a compact analytic semigroup, t--> a^t:H-->CL(X) such that (a^t X) = X and ||a^t||≤1 for all t G H, where H is the open right half of the Complex plane, a^t represents a compact operator on X and CL(X) denotes the set of all compact operators on X. Further, it is shown with a counter - example that the converse to the above result is false in general. In the process, we establish an enlightening result, namely, the scalar multiples of the identity operator are the only hermitians on the disc algebra.
