Lessons from the Case of Shell and the Ogoni ABSTRACT. This paper examines some of the paradoxes and dilemmas facing firms in the extractive sector when they attempt to take on a more stakeholder-responsive orientation towards issues of environmental and social responsibility.

of Its Properties Abstract Chitosan was prepared from shrimp processing waste (shell) using the same chemical process as described for the other crustacean species with minor modification in the treatment condition. The physicochemical properties‚ molecular weight (76 x 103g/mole)‚ degree of deacetylation (61%)‚ ash content as well as yield (15%) of prepared chitosan indicated that shrimp processing waste (shell) are a good source of chitosan. The water binding capacity (500%) and fat binding

These small holes are about two inches in diameter or big enough for a player to put five fingers at once. Shells‚ pebbles‚ or seeds are used as tokens. The board varies from 30 to 32 inches long‚ 7 to 9 inches wide‚ and 3 to 5 inches thick.

It was moved by a set timetable and the infantry was expected to follow closely as possible behind it. Also the first use of tanks‚ generation Mark I‚ baffled the Germans when it was first used‚ merely because it was unstoppable by any human means‚ except by a direct hit from an artillery shell.

When she got down there she saw a row of shells and followed them just like how her parents had taught her. The shells led to a little home with hundreds of other shells in different rows leading to the house. Dory saw two figures in the distance and when they saw her they ran to her. It was her parents finally. Dory was so happy to have found her parents
