Photonics research 2021年第2期9卷 252-258页

The direct interfacing of photonic crystal fiber to a metallic nanoantenna has widespread application in nanoscale imaging, optical lithography, nanoscale lasers, quantum communication, in vivo sensing, and medical *** report on the fabrication of a needle-shaped plasmonic nanoantenna on the end facet of a photonic crystal fiber using electron-beam-induced evaporation of platinum. We demonstrate the coupling of light from the fiber waveguide mode to the subwavelength nanoantenna plasmonic mode focusing down to the apex of the plasmonic needle using a polarization-resolved far-field side-scatter imaging technique. Our work provides an important step toward widespread application of optical fibers in nearfield spectroscopic techniques such as tip-enhanced raman and fluorescence microscopy, single-photon excitation and quantum sensors, nanoscale optical lithography, and lab-on-fiber devices.

Virtual Water on the Southern High Plains of Texas: The Case of a Nonrenewable Blue Water resource

引用

Natural resources 2015年第1期6卷 27-36页

作者： ryan blake Williams rashid Al-Hmoud Department of Agricultural and Applied Economics Texas Tech University Lubbock USA Department of Economics Texas Tech University Lubbock USA

This paper utilizes the virtual water concept to evaluate water usage of agricultural production in West Texas. This work evaluates the measure of virtual water, as it relates to informing water policy in a semi-arid, agriculture-intensive region, which relies upon a minimally renewable groundwater resource. The results suggest that production in the region reflects a collective effort to capture the highest value from the water resource, consistent with the virtual water philosophy, even in the absence of specific water policy toward that goal. Additionally, this work takes advantage of high resolution data to reinforce the need to calibrate virtual water calculations to account for regional differences.

“Doubling” of local photon emissions when two simultaneous, spatially-separated, chemiluminescent reactions share the same magnetic field configurations

引用

Journal of Biophysical Chemistry 2012年第1期3卷 72-80页

作者： blake T. Dotta Michael A. Persinger Biomolecular Sciences Program Laurentian University Sudbury Canada

The aim of the present experiments was to discern if the “entanglement”-like photon emissions from pairs of cell cultures or human brains separated by significant distances but sharing the same circling magnetic field could be demonstrated with a classic chemiluminescent reaction produced by hydrogen peroxide and hypochlorite. Simultaneous injection of the same amount of peroxide into a local dish (above a photomultiplier tube) and a dish 10 m away in a closed chamber produced a “doubling” of the durations of the photon spikes only when the two reactions were placed in the center of separate spaces around each of which magnetic fields were generated as accelerating group velocities containing decreasing phase modulations followed by decelerating group velocities embedded with increasing phase modulations. The duration of this “entanglement” was about 8 min. These results suggest that separate distances behave as if they were “the same space” if they are exposed to the same precise temporal configuration of magnetic fields with specific angular velocities.

Influence of Various Antioxidants on the Characteristics of Plain Yogurt

引用

Food and Nutrition Sciences 2012年第9期3卷 1277-1280页

作者： blake Brignac Kayanush J. Aryana Department of Food Science Louisiana State University Agricultural Center Baton Rouge LA School of Animal Sciences

Free radical damage has been implicated in ageing and in certain degenerative conditions such as Alzheimer’s disease and other forms of dementia. Ageing is also associated with a progressive decline in the function of the immune system and an increased susceptibility to infection. Antioxidants protect the body from free radical damage. Vitamin E is the major antioxidant vitamin in body tissues and is considered the first line of defense against cell membrane damage. Other antioxidant defenses that protect the body from free radical damage include vitamin C and beta carotene. Yogurt is considered a healthy food product and its sales have been steadily increasing over the past 5 years. The objective was to study the influence of various antioxidants on the quality characteristics of yogurt. The antioxidants Vitamin C, vitamin E and beta carotene individually and in combination were incorporated at 100% of their respective recommended dietary allowance of 60 mg, 12 mg and 3 mg in 240 mL of yogurt. Yogurt manufacture and all experiments were conducted in triplicate. Use of antioxidants in yogurt manufacture significantly influenced yogurt viscosity, flavor, appearance, body texture but did not influence syneresis, lactic acid bacterial counts and *** upon the application antioxidants can be recommended in yogurt manufacture.

作者： G.blake THOMAS Advanced Ergonomic Technologies Ltd 78a High StreetBletchingleySurreyRH1 4PAUK

＜正＞ In the last two years a dramatic increase in the use of underfloor air conditioning has occurred in Europe and the Far East. This is partly due to greater awareness of the suitability of the system in commercial office use, but also because of changes in business *** paper will use examples of projects, which currently use the underfloor system to highlight the customer and developer benefits that are available. It is primarily concerned with the concepts and major design issues that surround the system. These include the impact on construction cost, in addition to program and life costing （analysis）. It will draw on research undertaken on the normal performance of concrete slabs, and how these can be used as thermal stores along with computer simulated temperature pick up in floor *** supply and return systems （Constant volume supply/variable volume introduction） and floor supply and room or ceiling return systems （Variable volume supply/variable volume introduction） are discussed and compared with conventional ceiling based systems. Issues such as air quality, energy consumption, environmental impacts and demand on world resources, staff comfort and other topical matters related to current construction techniques will be raised throughout.
