Water containing ultra-fine bubbles (UFB) may promote plant growth. But, as UFBs are too small to distinguish from other impurities in a nutrient solution, it is not known if UFBs survive transport from the water source to the rhizosphere. Here we use the freeze-fracture replica method and a transmission electron microscope (TEM) to observe UFBs in the nutrient solutions used in a crop-growing ...

Permafrost thaw in peat plateaus leads to the flooding of surface soils and the formation of collapse scar bogs, which have the potential to be large emitters of methane (CH4) from surface peat as well as deeper, previously frozen, permafrost carbon (C). We used a network of bubble traps, permanently installed 20 cm and 60 cm beneath the moss surface, to examine controls on ebullition from thre...

Large cardamom is one of the most important spices that can significantly contribute to economical farming in country Nepal. It grown Nepal and north-eastern states India which provide suitable agroclimatic growing conditions high humidity, ambient temperature rainfall. Meeting demand for quality plants yield challenging with traditional methods propagation. The present study has used plant tis...

The reuse of drainages for cultivating more salt tolerant crops can be a useful tool especially in arid regions, where there are severe problems water management. Dracaena deremensis L. plants were cultured pots with sphagnum peat-moss and subjected to three fertigation treatments 8 weeks: control treatment or standard nutrient solution (D0), raw leachates from Chrysalidocarpus lutescens H. Wen...

the response to methimazole [1-methyl-2-mercapto-imidazole (mmi)] therapy, 10 mg twice daily in 15 patients and propylthiouracil (p tu) therapy, 100mg twice daily in 10 patients with diffuse toxic goiter was evaluated in an area of iodine deficiency (tehran). the mean free t4 index (ft4i) decreased from 22.7± 6.8 (± sd) to 10.8± 2.8 in mmi-treated, and from 25.1± 6.8 to 13.2± 2.1 in ptu-treated...

a factorial experiment based on completely randomized design with three replications was carried out in order to study the effect of different strains of mesorhizobium ciceri on chickpea tolerance under drought stress. in the first step of experiment, five native cultivars of chickpea (bivanij, arman, greet, jam and hashem) were inoculated with eight native (c-15, c-22, swri7, swri9 and swri4) ...

conclusions regular resistance training and prostatic massage can improve proinflammatory markers and psa levels in men with pc. results in the resistance training group, il-10 levels significantly increased after four (p = 0.055) and eight weeks (p = 0.000). four and eight weeks of resistance training showed a significant reduction in psa, crp, il-6, and tnf-α levels (p < 0.05). patients of ma...

This paper presents the compressibility of tropical peat reinforced with cylindrical cement columns. When a cement column is installed vertically in peat, its compressibility is reduced because of the hardened skeleton matrix formed by cement particles bonding with adjacent soil particles in the presence of pore water. The effects of the cement column diameter on the compressibility have been i...

     Due to the environmental problems caused by the accumulation of significant amounts of waste from peanut cultivation, it seems necessary to provide a solution for the reuse of this organic waste. Therefore, this experiment was conducted to investigate the possibility of using compost of peanut shells in potting Begonia rex. This research was based on randomized complete block desi...
