A set of natural units is determined from the “photon element” model of light, the outcome of an extended Compton analysis. In terms of these units, the speed of light and the electrical and Boltzmann constants are, respectively, on the order of unity, but the Planck constant is ∼1027 or greater and gravitational constant ∼10−59 or greater. This makes the photon element units less convenient than the Planck units. With the mass unit that is only ∼10−43 of the Planck mass, however, the photon element units can correspond better to physical realities than the Planck units. For the spacetime, a p

The Planck length is an object of the relativistic quantum-gravitational theory, therefore, a more general and consistent direction of the special relativity extension, seems to be the use of the postulate of the relativistically invariant and limiting nature of all Planck units, that was introduced by V.V. Korukhov at the end of the 90s. One of the examples of the implementation of this postulate in its methodological meaning is the model of a vacuum-like medium, the physical properties of which are characterized by relativistically invariant values, which qualita-tively distinguishes it from

Since 1889, the international prototype of the kilogram has served as the definition of the unit of mass in the International System of Units (SI). It is the last material artefact to define a base unit of the SI, and it influences several other base units. This situation is no longer acceptable in a time of ever-increasing measurement precision. It is therefore planned to redefine the unit of mass by fixing the numerical value of the Planck constant. At the same time three other base units, the ampere, the kelvin and the mole, will be redefined. As a first step, the kilogram redefinition requ

The space available to our perception is three-dimensional with full evidence. The development of physics led to the hypothesis of extra dimensions. It is believed that an important role in the unification of physics should play by the Planck units of mass, length and time, built on the universal constants c (the speed of light in a vacuum), G (the gravitational constant), and ħ (the reduced Planck constant). In August 2021, published work in which it is shown that the fundamental role in the unification of physics, in fact, was played by the Stoney units, built on the universal constants c −

Alfalfa is the second largest production crop grown in Arizona with an estimated 150,000 acres of production in 1993. Water requirements for alfalfa have been estimated at 6 acre-feet per year. These two facts together make it imperative that data be gathered to help growers apply their irrigation water efficiently while maintaining their yields. In 1994, a study was initiated in the Parker Valley region of La Paz County, Arizona, to measure daily water use in alfalfa. Two sites were chosen for measurement: one site was a surface irrigated field located at the Quail Mesa Farm; the second site

AbstractTraditional aquaponics systems were arranged in a single process loop that directs nutrient-rich water from fish to the plants and back. Given the differing specific nutrient and environmental requirements of plants and fish, such systems presented a compromise to the ideal conditions for rearing of both, thus reducing the efficiency and productivity of such coupled systems. More recently, designs that allow for decoupling of units provide for a more finely tuned regulation of the process water in each of the respective units while also allowing for better recycling of nutrients from s

The Indiana Dunes (comprised of 15 geographic units (see Figure 1) which include Indiana Dunes National Park, Dunes State Park, and adjacent Shirley Heinze Land Trust properties) are remarkable in the Midwest and Great Lakes region for the vascular plant diversity, with an astounding 1,212 native plant species in an area of approximately 16,000 acres! This high plant diversity is the result of the interactions among postglacial migrations, the variety of soil substrates, moisture conditions, topography, successional gradients, ?re regimes, proximity to Lake Michigan, and light levels. This ric

Annotation:

A vegetation classi?cation and map for Guadalupe Mountains National Park (NP) is presented as part of the National Park Service Inventory & Monitoring - Vegetation Inventory Program to classify, describe, and map vegetation communities in more than 280 national park units across the United States. Guadalupe Mountains NP lies in far west Texas and contains the highest point in the state, Guadalupe Peak (8,751 ft; 2,667 m). The mountain escarpments descend some 5,000 ft (1,500 m) to the desert basins below forming a complex geologic landscape that supports vegetation communities ranging from

This Technical Note suggests that the focus of policing should be on very small geographic units of analysis, such as street segments or small groups of street blocks. Crime at place is not simply a proxy for larger area or community effects; indeed, basic research evidence suggests that crime primarily occurs at very small geographic units of place. This research is reinforced by strong experimental evidence of the effectiveness of place-based policing in reducing crime and disorder so as not to displace crime to nearby areas. In addition, the perception of legitimacy should be a key componen

Solar collectors are the core components of solar district heating plants. Annual solar heat yield of solar heating plants on average is around 400-500 kWh/m2 in Denmark. Most solar collectors in the large solar district heating plants in Denmark are ground-mounted flat plate collectors. Arcon-Sunmark A/S is the main manufacturer of the large flat plate collectors for district heating in Denmark. Arcon-Sunmark A/S has installed more than 80% of the world’s large solar heating plants connected to district heating networks.

By the end of 2017, solar heating plants with a total surface of more than 1.3 million m2 were in operation in Denmark. Most solar collectors in the existing solar heating plants are typically flat plate collectors (FPC).
