Multifidelity multiobjective optimization for wake-steering strategies
Wake steering is an emerging wind power plant control strategy where upstream turbines are intentionally yawed out of perpendicular alignment with the incoming wind, thereby “steering” wakes away from downstream turbines. However, trade-offs between the gains in power production and fatigue loads…

The Effects of Surgical Antiseptics and Time Delays on RNA Isolated From Human and Rodent Peripheral Nerves
Peripheral Nerve Injury (PNI) is common following blunt or penetrating trauma with an estimated prevalence of 2% among the trauma population. The resulting economic and societal impacts are significant. Nerve regeneration is a key biological process in those recovering from neural trauma. Real…

Neuregulin 1 Drives Morphological and Phenotypical Changes in C2C12 Myotubes: Towards De Novo Formation of Intrafusal Fibres In Vitro
Muscle spindles are sensory organs that detect and mediate both static and dynamic muscle stretch and monitor muscle position, through a specialised cell population, termed intrafusal fibres. It is these fibres that provide a key contribution to proprioception and muscle spindle dysfunction is…

Wake steering optimization under uncertainty
Turbines in wind power plants experience significant power losses when wakes from upstream turbines affect the energy production of downstream turbines. A promising plant-level control strategy to reduce these losses is wake steering, where upstream turbines are yawed to direct wakes away from…

Alkali soil reclamation tests: Experiments in Tulelake Basin show encouraging improvements in soil after treatment with gypsum
Results in the reclamation of alkali soils in the Tulelake Basin have demonstrated that bad alkali soils can be reclaimed–or improved–by the use of soil correctives, irrigation, and proper drainage.

Brussels sprouts growth and nutrient absorption
Heavy fertilization is necessary for profitable Brussels sprouts production on new, relatively infertile land. About half of the nutrients taken up by the crop are removed during the first two-thirds of the growing season. Perhaps half of the nitrogen, and all of the phosphorus and potassium could…

Diagnosing potassium deficiency by soil analysis
Soil analysis, especially nitric acid extraction of potassium appears to be a very useful means of diagnosing potassium-deficient soils in California. Studies reported here compared two analytical methods for determining soil potassium levels. Plant growth responses were determined by greenhouse…

Sodium injury to cuttings of chrysanthemum
Following A change in the water supply used for irrigation and misting–from a shallow well (400 ft) to a deeper well (800 ft)–a large California chrysanthemum producer experienced extreme difficulty in rooting the cuttings. Early symptoms appeared as a loss of root hairs and small rootlets, and as…

Club root control in brussels sprouts using lime for pH adjustment
Club root, incited by Plasmodiophora brassicae (Woronin), is one of the most serious diseases of plants of the crucifer family and is a threat to crop production wherever it occurs. In heavily infested soil, it is capable of destroying a crop before it reaches market maturity.

Generating intrafusal skeletal muscle fibres : Current state of the art and future challenges
Intrafusal fibres are a specialised cell population in skeletal muscle, found within the muscle spindle. These fibres have a mechano-sensory capacity, forming part of the monosynaptic stretch-reflex arc, a key component responsible for proprioceptive function. Impairment of proprioception and…

Mind the gap—optimizing satellite tag settings for time series analysis of foraging dives in Cuvier’s beaked whales (Ziphius cavirostris)
Abstract Background Studies of deep-diving beaked whales using Argos satellite-linked location-depth tags frequently return data with large gaps in the diving record. We document the steps taken to eliminate these data gaps and collect weeks of continuous time series data for a behavioral response…

Spy in the sky: a method to identify pregnant small cetaceans
Abstract Data on sex ratios, age classes, reproductive success and health status are key metrics to manage populations, yet can be difficult to collect in wild cetacean populations. Long‐term individual‐based studies provide a unique opportunity to apply unoccupied aerial system (UAS)…

Global coverage of cetacean line-transect surveys: status quo, data gaps and future challenges.
Knowledge of abundance, trends and distribution of cetacean populations is needed to inform marine conservation efforts, ecosystem models and spatial planning. We compiled a geo-spatial database of published data on cetacean abundance from dedicated visual line-transect surveys and encoded >1100…

Rapid tissue testing for evaluating (2) nitrogen nutritional status of sorghum
THE STUDIES TO CALIBRATE the rapid tissue test with the nitrogen nutritional status of sorghum were conducted in a nitrogen deficient field on the Rosolia Ranch near Orland. In 1970, initial soil samples were taken and plots laid out in a randomized complete block design with six treatments and…

Rapid tissue testing for evaluating nitrogen nutritional status of (1) corn and (2) sorghum
For several years, rapid tisue tests have ben used in the field to evaluate plant nutritional status and to diagnose deficiencies. But they have ben used only incidentaly to make fertilizer recomendations, or to evaluate a fertilizer program, partly because they have lacked the acuracy of…

Plant uptake of bromide following soil fumigation with methyl bromide
The highest concentrations in plants grown on soils that have been fumigated with methyl bromide occur during the first year following fumigation.
