In this paper we present a numerical model for the simulation of non-isothermal air flow and corresponding heat transport in the unsaturated soil zone. The governing equations for non-isothermal gas flow and related heat transport are derived. The thermo-hydraulic (TH) coupling is additionally due to material properties, such as density, viscosity, heat diffusivity, which depends on the primary variables air pressure and temperature. A finite element model is developed for the solution of the resulting initial-boundary-value-problem. The numerical model is verified against analytical solutions for simplified problems. Finally, a case study for heat storage in soils is conducted.

We compared effects of different growing water potential conditions on physiological and morphological water–use properties of Sabina vulgaris Ant., which is an evergreen shrub that is widely distributed in arid and semi-arid environments of the Mu Us Sandy Land, China. Measurements were taken of cuttings grown for eight years under -0.02 MPa (control), -0.10 MPa (moderate water stress), and -0.34 MPa (severe water stress) water potential conditions. The transpiration rate (Tr) under moderate stress was significantly lower than that under severe stress and control water conditions (49% and 45% lower, respectively, than severe stress and the control on average). The leaf-specific hydraulic conductivity (LSC) in shrubs growing under moderate water stress was also significantly lower than for those under the severe water potential condition. In contrast, S. vulgaris growing under severe water stress had less leaf biomass than under moderate stress or control conditions. These results suggest that S. vulgaris growing under moderate water stress tends to show a reduced transpiration rate derived from its low LSC; therefore it avoids water loss in response to chronic water stress, while plants growing under severe water stress tends to reduce water loss through decreased leaf biomass. These results suggest that S. vulgaris has a high capacity for acclimation to different water potential conditions through physiological and morphological flexibility.

Eimeria tenella infection causes coccidiosis, which induces diarrhea and bloody stool in chicken. This infection impairs the epithelial barrier that lines the intestinal tract. The intercellular junctions are key factors for maintaining barrier integrity. However, information on the gene expression modulation of junctional molecule–related genes is still limited. This study aimed to elucidate the association between disease symptoms and the regulation of target genes. Intestinal function was evaluated using biomarker measurements. Gene expression regulation was determined by real-time quantitative polymerase chain reaction. The disruption of the intestinal barrier might be induced by lower levels of claudin-1, claudin-3, E-cadherin, occludin, and ZO-1 but higher levels of claudin-2. Our results might suggest the association between the modulation of junctional barrier molecules and major symptoms of E. tenella infection.

Investigations of the recent decades have revealed a significant lowering of the river bed of the Danube in Hungary. This phenomenon can be observed on a long stretch of the Hungarian Danube and it can be presumed that similar changes occur on other parts of the river beyond the borders. There are several methods to reveal and to measure the lowering of the channel. Long records of the water level are available for the trend- and homogeneity analyses. Results show that erosion processes started even at the beginning of the 20th century. In recent years results of bathymetry are available for the more detailed investigations of these changes. The main causes of the bed-lowering are river regulation activities, industrial dredging and decreasing of natural sediment load. Deepening of the river bed has unfavourable effects on the natural environment, on the navigation and also on the operation of man-made structures in the river. To avert these injurious effects a complex solution is needed, taking into consideration not just economical but ecological and social aspects as well.
