Water stress

This paper presents the experimental study on onedimensional compressibility behavior, soil water characteristic and soil shrinkage behavior of slurry Amberger kaolin. The volume change behavior of sample due to the suction and that due to applied vertical stress demonstrated a similarity within the saturation domain.

The scope of this work is threefold: (i) to develop a new model within the framework of hydro-mechanical – damage coupling that can account for the coupling between microcrack (damage), water diffusion and shrinkage at stake for concrete secondary creep; (ii) to implement it in an existing hydro-damage lattice model; (iii) to validate the model with respect to the flexural creep of Fiber Reinforced Concrete (FRC) and Mortars under high sustained load level.

Salinity is one of the most devastating abiotic stresses limiting crop production. Considering this issue, a pot experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the boro season (2017-2018) using two rice (Oryza sativa L.) varieties, namely BRRI dhan28 (salt sensitive) and BRRI dhan47 (salt tolerant), to assess the effects of varied salinity levels on the growth and the performance of the rice varieties under salt stress conditions.

Photoelasticity images of pulsed laser ablation in water and in air were simulated by Finite Element Method. In the paper "Compare transient stress induced in in-air and in-water laser ablation using simulation method", the Von Mises stress distribution in the target is deduced from the simulated images and is compared between the two-ablation regimes. The result confirms that pulse laser ablation in the water can induced a stress about 100 times higher than that induced in ablation in the air.

Water stress periods are common in rainfed agriculture therefore the activities aimed at conserving the rainwater should be adopted for improving the productivity of dryland crops. The major crops in Vidarbha region of Maharashtra are cotton, soybean and sorghum. It was observed that the drought situation may arise during crop growth period which may result in partial failure of crops. It was therefore felt worthwhile to adopt the proper methods of in-situ moisture conservation so as to partially meet out the adverse effect of water stress in standing crop.

Determine the coefficient of water permeability, waterproofing marks, chloride ion diffusion coefficients of some types of concrete commonly used in bridge construction subjected to pre-compressive and direct-compression loads. Develop a predictive model for life expectancy using reinforced concrete bridges taking into consideration the effect of the load according to the criteria of initial corrosion of reinforcement in concrete. Application of life expectancy for the structure of reinforced concrete bridges.

Rice is one of the most important crop plants over the world. Our work studied on the physiological responses of rice seedlings (Oryza sativa cv. Dongjin) under drought condition by withholding water. In response to drought treatment, three-week-old rice seedlings exhibited typically morphological responses as leafs rolling and drying at 48 h after exposure to water deficit.

This paper reports the results obtained using the osmotic stress method applied to the purified cathodic and anodic hemoglobins (Hbs) from the catfishHoplosternum littorale, a species that displays facultative accessorial air oxygen-ation. We demonstrate that water potential affects the oxy-gen affinity ofH. littoraleHbs in the presence of an inert solute (sucrose). Oxygen affinity increases when water activity increases, indicating that water molecules stabilize thehigh-affinitystateof theHb.

The endemic freshwater spongeLubomirskia baicalensislives in Lake Bai-kal in winter (samples from March have been studied) under complete ice cover at near 0C, and in summer in open water at 17C (September). In March, specimens show high metabolic activity as reflected by the produc-tion of gametes.
