degradation of natural resources
The result of the cumulative activities of farmers, households, and industries, all trying to improve their socio-economic well being. These activities tend to be counterproductive for several reasons. People may not completely understand the long-term consequences of their activities on the natural resource base. The most important ways in which human activity is interfering with the global ecosystem are: a) fossil fuel burning which may double the atmospheric carbon dioxide concentration by the middle of the next century, as well as further increasing the emissions of sulphur and nitrogen very significantly; b) expanding agriculture and forestry and the associated use of fertilizers (nitrogen and phosphorous) are significantly altering the natural circulation of these nutrients; c) increased exploitation of the freshwater system both for irrigation in agriculture and industry and for waste disposal.

climatic change
The long-term fluctuations in temperature, precipitation, wind, and all other aspects of the Earth's climate. External processes, such as solar-irradiance variations, variations of the Earth's orbital parameters (eccentricity, precession, and inclination), lithosphere motions, and volcanic activity, are factors in climatic variation. Internal variations of the climate system, e.g., changes in the abundance of greenhouse gases, also may produce fluctuations of sufficient magnitude and variability to explain observed climate change through the feedback processes interrelating the components of the climate system.

долгосрочное прогнозирование
Оценка будущего развития экономики, научно-технического прогресса, социальных изменений в обществе в долгосрочном периоде. В экономико-математических прогнозах эти стороны развития рассматриваются в единстве. Д.п. обычно относится к периоду в 10 - 15 лет, однако есть и так называемые сверхдолгосрочные прогнозы, или, правильнее, дальнесрочные, охватывающие существенно большие промежутки времени. Они, например, относятся к энергетике, градостроительству, лесному хозяйству, к состоянию природной среды. Как правило, подобные прогнозы существенно менее детализированы, чем кратко- и среднесрочные, в них шире применяются вероятностные оценки (см. Вероятность), а часто — и качественные суждения. Строятся научно-технические, социально-экономические и демографические прогнозы, каждый из которых объединяет и взаимоувязывает результаты многих частных прогнозов: развития тех или иных отраслей техники, производства товаров народного потребления, совершенствования экономического механизма и др. Основные методы прогнозирования в экономике, включая долгосрочное, приводятся в статье Прогнозирование.

Spring-cage terminals blocks from Phoenix Contact have been developed for universal spring-loaded conductor contacting. The contact force is independent of the user and creates a vibration-proof, gas-tight connection with long-term stability. The connection point is opened with a standard screwdriver.
After the conductor has been inserted into the terminal compartment, the screwdriver is removed and the conductor automatically makes contact.
The front connection facilitates convenient operation. This means that the conductor and the screwdriver come parallel from the same direction.
All kinds of copper conductors of up to 35 mm² can be clamped without pretreatment. Splicing protection can also be used in the form of ferrules.
Phoenix Contact spring-cage terminal blocks offer a large insertion space, i.e. conductors with nominal cross section that have ferrules can also be wired.
[Phoenix Contact]
Пружинные клеммы Phoenix Contact являются универсальными соединительными устройствами с пружинными зажимами. Усилие прижима не зависит от действий потребителя и обеспечивает долговременное стабильное вибростойкое газонепроницаемое соединение. Для присоединения проводника применяется стандартная отвертка.
После вставки проводника в отверстие клеммы, отвертка извлекается и жила проводника надежно прижимается пружинным зажимом к токоведущей части клеммы.
Выполнение монтажа является удобным, поскольку проводники вставляют спереди. Кроме того, проводник и отвертка вставляются в соответствующие отверстия клеммы параллельно друг другу в одном и том же направлении.
Пружинные клеммы допускают присоединение неподготовленных медных проводников любого типа сечением до 35 мм2, а также проводников с жилами, опрессованными кабельным наконечником.
Достаточно большие отверстия для вставки проводников позволяют присоединять проводники номинального сечения с кабельным наконечником.

mining site restoration
Mining is an intensive type of land use with potential for environmental impact over a limited area. When closure occurs, it should address both environmental and safety aspects. Mine reclamation is an ongoing program designed to restore to an acceptable state the physical, chemical and biological quality or potential of air, land and water regimes disturbed by mining. The objective of mine reclamation is to prevent or minimize adverse long-term environmental impacts, and create a self-sustaining ecosystem as near as practicable to what existed before the mining activity.

courant (permanent) admissible, m
valeur maximale du courant électrique qui peut parcourir en permanence, un conducteur, un dispositif ou un appareil, sans que sa température de régime permanent, dans des conditions données, soit supérieure à la valeur spécifiée
[IEV number 826-11-13]Ampacity, the term is defined as the maximum amount of current a cable can carry before sustaining immediate or progressive deterioration. Also described as current rating or current-carrying capacity, is the RMS electric current which a device can continuously carry while remaining within its temperature rating. The ampacity of a cable depends on:
- its insulation temperature rating;
- conductor electrical properties for current;
- frequency, in the case of alternating currents;
- ability to dissipate heat, which depends on cable geometry and its surroundings;
- ambient temperature.
Electric wires have some resistance, and electric current flowing through them causes voltage drop and power dissipation, which heats the cable. Copper or aluminum can conduct a large amount of current before melting, but long before the conductors melt, their insulation would be damaged by the heat.
The ampacity for a power cable is thus based on physical and electrical properties of the material & construction of the conductor and of its insulation, ambient temperature, and environmental conditions adjacent to the cable. Having a large overall surface area may dissipate heat well if the environment can absorb the heat.
In a long run of cable, different conditions govern, and installation regulations normally specify that the most severe condition along the run governs the cable's rating. Cables run in wet or oily locations may carry a lower temperature rating than in a dry installation. Derating is necessary for multiple circuits in close proximity. When multiple cables are near, each contributes heat to the others and diminishes the amount of cooling air that can flow past the individual cables. The overall ampacity of the insulated conductors in a bundle of more than 3 must be derated, whether in a raceway or cable. Usually the de-rating factor is tabulated in a nation's wiring regulations.
Depending on the type of insulating material, common maximum allowable temperatures at the surface of the conductor are 60, 75 and 90 degrees Celsius, often with an ambient air temperature of 30°C. In the U.S., 105°C is allowed with ambient of 40°C, for larger power cables, especially those operating at more than 2 kV. Likewise, specific insulations are rated 150, 200 or 250°C.
The allowed current in cables generally needs to be decreased (derated) when the cable is covered with fireproofing material.
For example, the United States National Electric Code, Table 310-16, specifies that up to three 8 AWG copper wires having a common insulating material (THWN) in a raceway, cable, or direct burial has an ampacity of 50 A when the ambient air is 30°C, the conductor surface temperature allowed to be 75°C. A single insulated conductor in air has 70 A rating.
Ampacity rating is normally for continuous current, and short periods of overcurrent occur without harm in most cabling systems. The acceptable magnitude and duration of overcurrent is a more complex topic than ampacity.
When designing an electrical system, one will normally need to know the current rating for the following:- Wires
- Printed Circuit Board traces, where included
- Fuses
- Circuit breakers
- All or nearly all components used
Some devices are limited by power rating, and when this power rating occurs below their current limit, it is not necessary to know the current limit to design a system. A common example of this is lightbulb holders.
