Rainfall and water requirement of rice during growing period

open access: yes, 2012
An experiment was conducted to estimate the crop water requirement of rice and to compare it with the amount of rainfall. Experiment was designed to estimate evaporation and evapotranspiration in cylindrical half cut mineral water bottles.

Evaluation of the Efficiency of CROPWAT Model for Determining Plant Water Requirement in Arid Regions [PDF]

open access: yesDesert, 2009
Shortage of water resources and increasing demand to consumption of this scarce resource, leads to somenoticeable limitations. On the other hand, population growth and consequently, increasing demand for water in aridand semi arid regions , needs ...

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Optimizing alternate brackish and freshwater drip irrigation with film mulching for cotton production in Southern Xinjiang

open access: yesGuan'gai paishui xuebao
【Objective】 Southern Xinjiang has limited freshwater but relatively abundant saline groundwater. To optimize the use of these water resources, we investigate the effect of alternate brackish and freshwater drip irrigation with film mulching on soil water

Identification of a Shiga toxin A‐derived peptide internalized into Gb3 receptor‐bearing cells via interaction with the Shiga toxin B subunit

open access: yesFEBS Letters, EarlyView.
The process of internalization of the Shiga toxin A subunit via formation of a complex with the Shiga toxin B subunit, which specifically binds to the Gb3 receptor. The peptide is designed to act as a carrier of drugs into cancer cells. Here, we explored the potential of peptides derived from the catalytic A subunit of Shiga toxin (STxA) to be drug ...

The Water Requirements of Broilers

open access: yesPoultry Science, 1962
Abstract WET LITTER in poultry houses is a problem of considerable economic importance. Charles et al. (1942) reported that water can become a problem in poultry litter management. Eley and Hoffman (1949) suggested that the level of dietary protein may affect the amount of moisture in the droppings which should in turn directly affect the moisture ...

Nutrient/TOR signaling controls adipose mitochondrial transcription factor A (TFAM) to regulate organismal growth in Drosophila

open access: yesFEBS Letters, EarlyView.
Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...

The Effect of Sprinkler Irrigation on Grain Yield, Yield Components and Water Use Efficiency of Rice Cultivars under Drill-Seed Cultivation in Khuzestan [PDF]

open access: yesعلوم و مهندسی آبیاری, 2019
Water scarcity is a major constraint in the development of rice farming in some parts of the world. In many areas, the volume of water consumed in the field and during the growing season of rice is usually more than the actual requirement due to ...
