Mixed crop-livestock systems, combining livestock and cash crops at farm level, are considered to be suitable for sustainable intensification of agriculture. Ensuring the survival of mixed crop-livestock systems is a challenge for European agriculture: the number of European mixed crop-livestock farms has been decreasing since 1970. Analysis of farming system dynamics may elucidate past changes...
Urban development is a complex process influenced by a number of driving forces, including spatial planning, topography and urban economics. Identifying these drivers is crucial for the regulation of urban development and the calibration of predictive models. Existing land-use models generally consider urban development as a binary process, through the identification of built versus non-built a...
objectives: most studies have performed to identify the affective variables in using mobile phone by drivers based on interview and questionnaire. in this study call answering rate while driving was investigated in a sample of male postgraduate students of a university in tehran by a driving simulator. methods: six driving scenario designed differing in risk of driving. answer rate to mobile ph...
Objectives: One of the applications of ergonomics disciplinary is designing driver workstation compatible to users’ characteristics. The aim of this study was evaluation of interior design of Shoka vehicle with respect to the accommodation for Iranian population and proposing suggestions for customizing design of the vehicle. Methods: This study was a descriptive-analytical study conducted a...
Environmental gradients caused by hydrological changes, whether natural or maninduced, affect the planktonic taxonomic and functional composition in shallow water ecosystems. In this sense, our aim was to find out the main variables or variable ratios that are the driving forces of the major phytoplankton taxonomic groups in Mediterranean coastal lagoons. For this purpose, 11 waterbodies were c...
Climate change cannot control unless by reduction of GHG emissions to secure level, therefore it is important to identify driving forces and possible scenarios based on targets. In this research, the Logarithmic Mean Divisia Index decomposition approach in combination with Extended Kaya Identity (EKI) are applied to investigate five factors could affect emissions during 1971-2012 in Iran. Thes...
Introduction: Considering the importance of driving and the resulting injuries, we can point to the relationship between human characteristics and driving behaviors. Therefore, the aim of this study was to develop a structural model of driving behaviors on the basis of aggression mediated by emotion regulation. Method: This research was applied in terms of purpose and descriptive-correlatio...
the presence of heavy metals anomalies in groundwater resource and their effect on human health through both drinking water and agricultural activities is a serious worldwide. because of with the distribution of these elements in groundwater of malikan plain, the information does not exist, this study were performed to evaluate heavy metals, especially arsenic in groundwater and to determining ...
32 F420 coenzyme models with alkylation of the three different N atoms (N1, N3 and N10) in the core structure (XFH(-)) were designed and synthesized and the thermodynamic driving forces (defined in terms of the molar enthalpy changes or the standard redox potentials in this work) of the 32 XFH(-) releasing hydride ions, hydrogen atoms and electrons, the thermodynamic driving forces of the 32 XF...
The Galápagos Marine Reserve (GMR) has faced major governance challenges since its designation in 1998, largely due to the driving forces of immigration from the mainland; a heterogeneous population that has a mainland rather than an island identity; increasing demand for marine resources from global seafood markets; and the rapid growth of tourism. Until recently, the pressures related to thes...
