【高端论坛】第53期:From Acidity to Equilibrium: Harnessing Liming to Curtail N2O Emissions and Fortify Soil Health。
Increased acidity in the atmosphere is disrupting the ecological balance of the oceans, according to new research. The study looks at acidity's impact on nutrient transport to the ocean and demonstrat...
Estimates of dry and wet deposition of sulphur and nitrogen were compared with critical loads of sulphur and nitrogen in the Czech Republic on 1 ×1 km grid. Deposition was estimated from monitored a...
Emissions and ecological factors are evident in changes of dynamics of global forest ecosystems. Specific develop-ment takes place in these substitute stands on contaminated and devastated plots. The ...
RIVERSIDE, Calif. — California’s water supply depends on a clean snow pack and healthy mountain lakes. The lakes receive a large amount of runoff in the spring from the melting snowpack. If the snow...
The effect of thickening agents – methyl cellulose, hydroxyethyl cellulose, sodium carboxymethyl cellulose, and xanthan gum – solutions on the sensory viscosity was investigated in the concentration r...
A novel azo derivative, 2,3,4,6'-tetrahydroxy-3'-sulfoazobenzene (THSA), was synthesized by using pyrogallol. The acid dissociation constants, or Ka values, of THSA were determined by the UV-visible s...
The acidity of precipitation has been observed at stations of the Acid Rain Monitoring Network run by the China Meteorological Administration (CMA-ARMN) since 1992. Previous studies have shown that di...
This study concerns the influence of turning and fermentation method on quality of raw cocoa. Fermentation trials were conducted in wooden box, plastic box and in heaps with or not turning. Cocoa fer...
Fe-PILCs via different conditions using smectites from Hancili (Turkey) and Wyoming (USA) were synthesised. Presaturation had little effects on the basal spacing values while it had important effects ...
华南理工大学食品分析课件Chapter5 Acidity
High precipitation amounts of strongly varying ionic composition make the western parts of southern Norway well-suited for studies of certain relationships between precipitation chemistry, hydrology...
Acid sulphate (AS) soils cover extensive areas of the coastal plains in western Finland. These soils constitute an environmental hazard due to their ability to relcase acidity when exposed to atmosp...
Our recently developed potential characterization method for studying the zeolite acidity is reviewed. In this method, ammonia TPD is a principle technique and first the principle of the method was ex...
研究了宫川温州蜜柑糖度及有效酸度的机器视觉检测技术及影响检测精度的因素。对机器视觉系统采集的柑橘图像进行图像裁切、亮度法去图像背景和RGB空间至HSI空间的转换,将柑橘色调范围分割为0°~20°、20°~40°、40°~60°、60°~80°、80°~100°和100°~120°共6个区域,提取各区域色调分形维数,以此作为BP神经网络输入,无损检测宫川温州蜜柑糖度及有效酸度。167个测试样本的检测...
