The property of phosphorus (P)-doped titanium(IV) oxide (TiO2) films prepared using phosphide was compared with that of nitrogen (N)-doped TiO2 films prepared using nitride. X-ray diffraction analysis showed that the crystallite size of P-doped TiO2 film was larger than that of N-doped ...
都呈显著正相关.因此,要降低水体中氮磷浓度,可以从减少通过干湿沉降进入湖泊水体的氮磷或者降低沉积物再悬浮、抑制底泥氮磷释放两个方面入手.关键词:蠡湖;氮磷;时空变化;富营养化;生态修复中图分类号:X524文献标识码:A文章编号:1000-6923(2014)05-1268-09Spatial-temporaldynamicchangesofnitrogenandphosphorusand...

Wastewater often contains large amounts of the nutrients nitrogen and phosphorus in the form of nitrate and phosphate, which promote plant growth. Organisms only require small amounts of nutrients in biological treatment, so there normally is an excess available in treated wastewater. In severe cases...
The two cultivars were used to evaluate the growth,nutrient use efficiency and tolerance to nitrogen( N),phosphorus( P)and potassium( K) stresses,which will provide information for the localization of tolerance genes and improvement of heredity in wheat breeding in the future. 【Methods】A pot ...
What is the difference between growth and development in plants? Kingdom Plantae Kingdom Plantae is a taxonomic group that includes ferns, algae, liverworts, and green plants. They are mostly eukaryotic and multicellular, with a few exceptions. At the cellular level, they have cell walls make ...

Further, studies on the sex-based association among nutrition, muscle mass, and strength would be helpful in choosing optimal interventions to improve the strength of patients on dialysis. The study aimed to assess the association between these three variables using mediation analysis. This ...
Phosphorus, symbolized as "P", is a key element in DNA, RNA, and ATP, fundamental to life's biochemical processes. Molybdenum, denoted as "M" in certain contexts (though its chemical symbol is Mo), is crucial in enzymes for nitrogen fixation and sulfur metabolism in living organisms. While...
