Weather climate

The warm-weather climates necessary for citrus orchards generally minimize the risk of frost conditions. Nevertheless, occasionally measures are needed to protect the trees and their fruit from freezing temperatures. Citrus crops become threatened when temperatures fall below 28°F for four hours or moreJ l Heating... 

A review of the available literature allows a hierarchical ranking of the importance of different factors that influence the pre-harvest infection of cereal grains by Fusarium weather/climate (year) > inoculum pressure/tillage/ previous crop > fungicides > available plant nitrogen. The individual factors related to other fungi are described in separate sections below. 

Canada also reports industry capabilities in the production of 5-20 kW SOFCs. Residential and commercial applications are being demonstrated in Europe, the US and in cold weather climates including Alaska. Canada s research efforts are focused on developing "noval-nano" based materials and noval architecture to enable lower temperature, direct fuel, SOFC operation. 

For any activated carbon system, the capital costs will be dependent on contaminant types and concentration as well as treatment goals. Capital costs will also increase in cold-weather climates, since systems may require buried piping, heating, and housing units. The major contributors to operations and maintenance (O M) costs are treatment/replacement of spent carbon, disposal of residuals, and monitoring effluent concentrations (D11022L, p. 11-100). Also, activated carbon systems are usually part of a treatment train. Treatment costs will be highly dependent on the other systems used to deliver the contaminants to the activated carbon unit.

Abiotic factors affect succession by way of the species that colonize the area. Certain species will or will not survive depending on the weather, climate, or soil makeup. Biotic factors such as inhibition of one species due to another may occur. This may be due to some form of competition between the species. 

Contractors need to be fully informed on the weather climate at the site. Basic data on prevailing conditions can be obtained from a number of sources as shown in Box 4.1. 

The fluid in these cadence-responsive knee units may be oil (hydraulic) or air (pneumatic). For hydraulic knees, the fluid is incompressible. The resistance to piston motion results from fluid flow through one or more orifices. As such, the resistance is dependent on the fluid viscosity and density, the size and smoothness of the channel, and the speed of movement. In contrast, for pneumatic knees, the fluid is compressible. The resistance is again due to fluid flow through the orifice(s) but is also influenced by fluid compression. Since air is a gas, potential leaks in pneumatic knee units will not result in soiled clothing, unlike what may occur with hydraulic knees. In addition, since air is less dense than oil, pneumatic units tend to be lighter than hydraulic units. However, since air is less dense and less viscous than oil, pneumatic units provide less cadence control than hydraulic units. Note that since viscosity is influenced by temperature, hydraulic (and pneumatic) knee units may perform differently inside and outside in cold weather climates. An example of a hydraulic cadence-responsive knee unit is the Black Max (USMC, Pasadena, Calif.). Additional examples include the Spectrum Ex (pneumatic, Hosmer, Campbell, Calif), Pendulum (pneumatic, Ohio Willow Wood, Mt. Sterling, Ohio), and Total Knee (hydraulic. Model 2000, Century XXII Innovations, Jackson, Mich.), which combine a cadence-responsive resistance swing-phase-control knee with a four-bar polycentric stance control knee. 

Atmospheric models for research and forecasting of weather, climate, and air quality are all based on numerical integration of the basic equations governing atmospheric behavior. These equations are the gas law, the equation of continuity (mass), the first law of thermodynamics (heat), the conservation equations for momentum (Navier-Stokes equations), and usually equations expressing the conservation of moisture and air pollutants. At one extreme, atmospheric models deal with the world s climate and climate change at the other extreme, they may account for the behavior of local flows at coasts, in mountain-valley areas, or even deal with individual clouds. This all depends on the selected horizontal scale and the available computing resources ...

The degradation dynamics of polyhydroxyalkanoates of different compositions (a PHB homopolymer and a PHB/PHV copolymer with 14mol% of hydroxyvalerate) have been studied in a eutrophic storage reservoir for two seasons. It has been shown that the biodegradation of polymers under natural conditions depends not only on their structure and physicochemical properties but also, to a great extent, on a complex of weather-climatic conditions affecting the state of the reservoir ecosystem. 

Environment is defined as the surroundings within which the system works, including people, weather, climate conditions, traffic density, etc. The system can be self contained i.e. there can be no interactions between the system and its environment, or the system can be embedded , i.e. the system receives inputs from the environment and is passing outputs into the environment to fulfil its fimctioa The embedded systems can also receive the behaviour rules and distuibances from the enviromnent, and can pass the distuibances into the environment... 

Environment is the natural environment (weather, climate, ocean conditions, terrain, vegetation, space conditions) combat environment (dust, fog, nuclear-chemical-biological) threat environment (effects of existing and potential threat systems to include electronic warfare and communications interception) operations environment (thermal, shock, vibration, power variations) transportation and storage environment maintenance environment test environments manufacturing environments (critical process conditions, clean room, stress) and other environments (e.g., software engineering environment, EM) related to system utilization. 

Earth resistivity, as mentioned earlier, is weather/climate dependent. The resistivity after the rains is lower than that measured during dry days. Also, it may be frequency dependent. The frequency dependence of earth permittivity may be far more significant than that of earth resistivity. Furthermore, water (H2O), which is a dominant factor for earth permittivity, is extremely temperature dependent [18]. As a result, the error due to the uncertainty of earth resistivity and permittivity might be far greater than that due to the incompleteness of the earth-return impedance derived by Carson and Pollaczek. This should be remembered as a physical reality that is important in engineering practice.
