Controlled Irradiative Formation of Penitentes

open access: yes, 2006
Spike-shaped structures are produced by light-driven ablation in very different contexts. Penitentes 1-4 m high are common on Andean glaciers, where their formation changes glacier dynamics and hydrology.

Leveraging Machine Learning to Predict Food Waste Quantity: Focusing on Military Dining Facilities as Large‐Scale Food Service Operations

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT Food waste reveals inefficiencies in resource use and contributes significantly to environmental pollution. In the United States, food waste accounts for the majority of total waste, with more than 50 million tons generated annually. In military units that operate large‐scale institutional food‐service facilities and generate significant food ...

Evolution of PAHs in photodissociation regions: Hydrogenation and charge states

open access: yes, 2013
Various studies have emphasized variations of the charge state and composition of the interstellar polycyclic aromatic hydrocarbon (PAH) population in photodissociation regions (PDRs). We aim to model the spatial evolution of the charge and hydrogenation

Thermochronologic Constraints on the Extensional History of the Ibex Hills, Southeastern Black Mountains, Death Valley, California

open access: yesGeological Journal, EarlyView.
A. Modeled T‐t paths for samples in the northern Ibex Hills, showing steady cooling throughout much of the Cenozoic, until rapid Miocene cooling. B. Weighted mean paths for each sample in this study. Note that all show a rapid cooling event at or just after 10 Ma, which is interpreted to represent exhumation as a result of regional extenstion ...

Seasonal drivers of plant–soil–microbial community structure and functions in Western Himalayan grasslands, Pakistan

open access: yesGrassland Research, EarlyView.
Plant species richness was greater in summer in both alpine and subalpine grassland ecosystems. Soil moisture demonstrates significant positive correlations with soil organic carbon and total nitrogen across seasonal periods. Microbial α‐diversity peaks during summer but maintains functional stability across seasons.

Evaluation of the Land Surface Water Budget in NCEP/NCAR and NCEP/DOE Reanalyses using an Off-line Hydrologic Model [PDF]

open access: yes, 2001
The ability of the National Centers for Environmental Prediction (NCEP)/National Center for Atmospheric Research (NCAR) reanalysis (NRA1) and the follow-up NCEP/Department of Energy (DOE) reanalysis (NRA2), to reproduce the hydrologic budgets over the ...

Human appreciation of flower colours as cultural ecosystem service in grasslands: A methodological approach

open access: yesGrassland Research, EarlyView.
This literature‐based method estimates human appreciation of flower colours on target grasslands. Step 1: search literature sources (floristic surveys, national floras, web datasets and preference studies). Step 2: flower trait extraction (flower colour and area, flowering period and human colour appreciation scale).

Transformative changes of pastoral livestock production and its consequences on the Qinghai–Xizang Plateau

open access: yesGrassland Research, EarlyView.
Grassland functional zoning and spatial optimization scheme on the Qinghai–Xizang Plateau. Based on multifunctionality assessment, the scheme proposes allocating 32% of regional grassland as nature reserve grasslands (biodiversity focus), 63% as livestock grazing grasslands (smart ecological–production management), and 5% as cultivated grasslands (high‐
