Abstract:

Greenhouse gases (GHG), mainly methane (CH4) and carbon dioxide (CO2), can be generated in agricultural activities, not only in waste but also in the process of breathing of livestock. The Theory of Inventive Problem Solving (TRIZ) is an innovative Russian methodology that allows finding the solution to a problem raised. This paper presents the use of two TRIZ tools to design a non-invasive prototype that detects CH4 and CO2 emitted by cattle in real time. The tools were the matrix of technical contradictions and the nine-screen analysis with which the parameter to be improved (A) was found and the best possible solution to design a prototype that allows quantifying gases for animal welfare, Final Ideal Result (IFR) a wireless module with a sensor system for each of the gases placed on the bovine head, which convert the detected gas into an electrical signal to be sent wirelessly to a range of 1.5 km in free space at a receiver for its visualization representing the parts per million (ppm) of CH4 and CO2 that the bovine is generating during the measurement.

Abstract:

Vegetative pots experiments were carried out at the Phytotron of the Lithuanian Institute of Horticulture in the period between January and September 2005. Four levels of CO2 concentration: 350 ppm (control treatment), 700 ppm, 1500 ppm, 3000 ppm and two levels of temperature regimes: 21oC/17oC (control treatment) and 25°C/21°C, photoperiod of 16/8 h, and their combinations were used in testing Chenopodium album L. early growth. The level of radiation (PAR) was 170 micro-mol m-2 s-1.Experimental data proved that the concentration of CO2, which had been graduallyincreasing and reached 1500 ppm, added to the length of Chenopodium album L. sprouts and increased the biomass of sprouts and roots. Chenopodium album L. was not able to adapt to further increase of CO2 concentration and had a tendency to retard the early growth. Increase of the environment temperature to 25°C/21°C initiated more intensive early growth of Chenopodium album L. increasing sprout length and quantity of the accumulated biomass. However, under the conditions of 25oC/21oC, the 700 ppm concentration of CO2 already had a negative impact on the early growth of Chenopodium album L.
