Regional onset of Holocene drying period estimated from sand deposit analyses in Kharga Oasis, Western Desert, Egypt

Journal of Quaternary Science, EarlyView.
ABSTRACT Desertification in North Africa has progressed rapidly over the past 6000 years. The occupation of Egypt by the Achaemenid Persians and Romans occurred even in hyperarid climates. Understanding the process of environmental changes on a regional scale may improve knowledge of how people developed technologies and adapted to the natural ...

The Stability of Manganese Oxides Under Laser Irradiation During Raman Analyses: II. Layer Structures

Journal of Raman Spectroscopy, EarlyView.
Manganese oxides are important geomaterials with diverse technological applications. Here, we investigate the behaviour of the most common Mn oxides with layer structures under irradiation by a 532‐nm laser, with intensity ranging from 23 µW/µm2 to 36.8 mW/µm2.

Microplastics Identification in Remote Aquatic Environments Using Raman Spectroscopy: A Case Study for Mt. Tymfi's Alpine Lake

Journal of Raman Spectroscopy, EarlyView.
This work contributes to the literature on the detection of MPs in Greece, proposes a method for MPs extraction in remote environments taking into account fieldwork constraints of an expedition in the Greek Alps, and takes a step forward in MPs analysis by Raman spectroscopy. ABSTRACT Water samples from the alpine lake of Mt.

Optimizing nitrogen application frequency to enhance the post‐flowering matter accumulation, yield and water/nitrogen use efficiency of densely planted and drip‐irrigated maize

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Maize yield stability is crucial for China's national food security. Conventional irrigation and nitrogen application methods have problems like low yield, inefficiency and environmental pollution. Optimizing water/fertilizer management is therefore imperative.
