Chemistry Applied to Agriculture

Physical chemistry applied to anaesthetic action.

The "dose" of inhalational anaesthetics is commonly expressed in terms of volume per cent (vol/vol) of the agent in an inspired or end-tidal gas sample. However, the "dose" should be expressed more correctly as a partial pressure which can be calculated as the fractional concentration multiplied by the total pressure of the system (e.g. the partial pressure of oxygen in air=0.21x760 = 160 mm Hg...

Metadiscourse in Applied Linguistics and Chemistry Research Article Introductions

This study examined disciplinary rhetoric in research articles, focusing on different traditions in structuring text discourses from a metadiscourse-move analytic approach. The corpus consisted of 72 research article Introductions (RAIs): 36 in applied linguistics and 36 in chemistry. Swales’ CARS model (1990, 2004) and Hyland’s interpersonal model of metadiscourse (2005) were used as analytica...

A survey of wireless sensor technologies applied to precision agriculture

This paper gives a state-of-art of wireless sensor network (WSN) technologies and solutions applied to precision agriculture (PA). The paper first considers applications and existing experiences that show how WSN technologies have been introduced in to agricultural applications. Then, a survey in hardware and software solutions is related with special emphasis on technological aspects. Finally,...
