For determining interactive plant-bacterial effects between glucosinolates and phyllospheric colonization by a plant growth-promoting strain, Enterobacter radicincitans DSM 16656, in cruciferous vegetables, the extent of bacterial colonization was assessed in 5 cruciferous vegetables (Brassica juncea, Brassica campestris, Brassica oleracea var. capitata, Brassica rapa var. alboglabra, Nasturtiu...

Rising atmospheric CO2 concentrations can fertilize plant growth. The resulting increased plant uptake of CO2 could, in turn, slow increases in atmospheric CO2 levels and associated climate warming. CO2 fertilization e ects may be enhanced when water availability is low, because elevated CO2 also leads to improved plant water-use e ciency. However, CO2 fertilization e ects may be weaker when pl...

The concepts of electronic government and electronic democracy have common roots in that electronic government must rest on, and support, democratic principles. This article discusses how the components of a democratic society are treated as they are built into the emerging electronic infrastruc-tures, dealing with services and dialogues pertinent to the functioning of the public sector, and tr...

This chapter, as a case study would like to put forward a pioneering programme of the United Nations Development Programme (UNDP) that acted as catalytic factor in many developing countries initiating from 1992. Many of projects under this programme, namely the sustainable development networking programme (SDNP) lead the country ́s information technology sector and eventually act as a positive c...

Excess specific heat, C(p)()(E), of binary mixtures of selected components of plant cuticular waxes has been determined. This thermodynamic parameter gives an explanation of the special molecular arrangement in crystalline and amorphous zones of plant waxes. C(p)()(E) values indicate that hydrogen bonding between chains results in the formation of amorphous zones. Conclusions on the self-asembl...

Studying plant phenology is very important to regulate the rangeland utilization. Plant phenology can be determined by Growing Degree Days (GDDs). Since temperature varies yearly, the phenological stages may consequently differ yearly. Determining the base temperature is one of the key steps in the calculation of GDDs. The aim of this study was to calculate the required GDDs for each phenologic...

The hybrid control systems considered here consist of a continuous plant under the control of a discrete event system. Communication between the plant and controller is provided by an interface that can convert signals from the continuous domain to the symbolic domain, and vise-versa. Hybrid control system design generally involves designing a controller, possibly designing some or all of the i...

The effects of elevated CO2 (E-CO2) on maize and Asian corn borer (ACB), Ostrinia furnacalis, in open-top chambers were studied. The plants were infested with ACB and exposed to ambient and elevated (550 and 750 μl/l) CO2. E-CO2 increased the plant height and kernel number per ear. The plants had lower nitrogen contents and higher TNC: N ratios under E-CO2 than at ambient CO2. The response of p...
