New organic matter degradation proxies: Valid in lake systems? [PDF]

open access: yes, 2004
We determined concentrations and diagenetic state of organic matter in two cores from Lake Zug, Switzerland. To obtain a general picture of organic matter decay in the lake, we measured bulk parameters such as total organic carbon, total nitrogen, and ...

Phosphorus release from the soils in the Yellow River Delta: dynamic factors and implications for eco-restoration

open access: yesPlant, Soil and Environment, 2015
Root-released organic acids are reported to increase phosphorus (P) availability in the soil. In this study a dynamic study of P release from soil was conducted to get more exact information of the organic acids role in P availability in soil.

The role of different natural organic acids in postharvest fruit quality management and its mechanism

open access: yesFood Frontiers, 2023
Fresh fruits have good flavor and high nutritional value, but in the postharvest stage they will age and decay rapidly, so we need to find green postharvest fruit preservatives.

Nutraceutical profiles of apricots (Prunus armeniaca L.) as a source of fruit quality traits for breeding

open access: yesSpanish Journal of Agricultural Research, 2021
Aim of study: In a social context of increasing concern about healthy diets, the development of new varieties with enhanced content in nutraceutical compounds is an important objective of the fruit breeding programs currently developed.

Potentials to differentiate milk composition by different feeding strategies [PDF]

open access: yes, 2009
To investigate the effect of the dietary intake of the cow on milk composition, bulk-tank milk was collected on 5 occasions from conventional (n = 15) and organic (n = 10) farms in Denmark and on 4 occasions from low-input nonorganic farms in the United ...

Real-time measurements of gas-phase organic acids using SF6 chemical ionization mass spectrometry [PDF]

open access: yesAtmospheric Measurement Techniques, 2018
The sources and atmospheric chemistry of gas-phase organic acids are currently poorly understood, due in part to the limited range of measurement techniques available.

A note on the effect of supplementation with microbial phytase and organic acids on feed intake and growth performance of growing pigs [PDF]

open access: yes, 2008
peer-reviewedThis experiment was designed to investigate the effects of supplementation with phytase, either alone or in combination with organic acids, on feed intake and growth of pigs from 8 to 89 kg live weight.

Atomic Structures of Molecules Based on Additivity of Atomic and/or Ionic Radii [PDF]

open access: yes, 2009
The authors have shown in recent years that interatomic and interionic distances are sums of the radii of the adjacent atoms and/or ions. Many examples will be provided and it will be shown how the experimental bond lengths agree with the radii sums. The
