Since he can neither accept nor reject them all, he must be governed by the time and energy available for his prime professional obligations.

Since the relation between changes in Gibbs free energy ( G ), the enthalpy ( H ) and the entropy is

Since this process does not involve any heat transfer or work, the First Law of Thermodynamics then implies that the net internal energy change of the system is zero.

Since meat has a higher energy density than vegetables, and cooking it allows more nutrients to be liberated to the body, the introduction of cooked meat in the human diet reduced the energy requirements of the digestive system.

Since the start of the " Special Period " in 1991 ( energy shortages caused by the loss of the Soviet Union as a trading partner ), hitchhiking and carpooling have become important parts of Cuba's transportation system and society in general.

Since it is time-consuming to calculate the energy for a molecule, it is even more time-consuming to calculate them for the entire list of points in the Brillouin zone.

Since the value of this energy depends on the shapes and positions of the conductors and dielectrics, the Casimir effect manifests itself as a force between such objects.

Since such radiation can produce severe damage to life at powers that produce very little heating, it is considered far more dangerous ( in terms of damage-produced per unit of energy, or power ) than the rest of the electromagnetic spectrum.

Since electrical energy cannot easily be stored in quantities large enough to meet demands on a national scale, at all times exactly as much must be produced as is required.

Since the free energy is the maximum amount of work that can be extracted from a system, one can write:

Since work is defined as a force acting through a distance ( a length of space ), energy is always equivalent to the ability to exert pulls or pushes against the basic forces of nature, along a path of a certain length.

Since 1918 it has been known that the law of conservation of energy is the direct mathematical consequence of the translational symmetry of the quantity conjugate to energy, namely time.

Since the kinetic energy of a molecule is proportional to its temperature, evaporation proceeds more quickly at higher temperatures.

Since unsaturated fats contain fewer carbon-hydrogen bonds than saturated fats with the same number of carbon atoms, unsaturated fats will yield slightly less energy during metabolism than saturated fats with the same number of carbon atoms.

Since the stored energy in the barrier is less than the energy stored in a barrier-free region of the same length due to destructive interference, the group delay for the energy to escape the barrier region is shorter than it would be in free space, which according to Winful is the explanation for apparently superluminal tunneling.

Since the heat source that supplies thermal energy to the engine can thus be powered by virtually any kind of energy, heat engines are very versatile and have a wide range of applicability.

Since the stopping force F times that distance must be equal to the head's kinetic energy, it follows that F will be much greater than the original driving force f — roughly, by a factor D / d.

Since the early 20th century, the term is used almost exclusively in conjunction with the modern development of hydro-electric power, which allowed use of distant energy sources.

Since the potential energy depends on the spatial arrangement of the particles, the kinetic energy will also depend on the spatial configuration to conserve energy.

Since the 1990s, SO < sub > 2 </ sub > emissions have dropped 40 %, and according to the Pacific Research Institute, acid rain levels have dropped 65 % since 1976.

Since the mid-20th century, there has been considerable debate over how the earliest forms of life evolved and how to classify them, especially at the kingdom and domain levels and organisms that are or have been considered bacteria.

Since all structural levels of the protein determines its function, the protein can no longer perform its function once it has been denatured.

Since Version 0. 7, Freenet offers two different levels of security: Opennet and Darknet.

Since originally taking interest in climate studies in the 1970s, Dyson has suggested that carbon dioxide levels in the atmosphere could be controlled by planting fast-growing trees.

Since carbon monoxide is a colorless, odorless and tasteless gas, and poses a potentially fatal threat, detectors have become commercially available to warn of dangerous levels in residences.

Since air and water are governed by similar fluid equations, albeit with vastly different levels of viscosity, density, and compressibility, the hydrofoil and airfoil create lift in identical ways ( see foil ( fluid mechanics )).

Since mid-2009, oil export earnings have returned to levels seen before Operation New Dawn and government revenues have rebounded, along with global oil prices.

Since the disintegration of the Soviet Union, the city's industries have experienced a severe decline, creating high levels of unemployment.

Since the actual physical surface of the Earth is too complex for mathematical analysis two levels of abstraction are employed in the definition of these coordinates.

Since 2001, trim levels are also indicated by including a number after the main index: '- 00 ' means base trim level, '- 01 ' means standard trim and '- 02 ' designates deluxe version ; for example, VAZ-21121-02 means Lada 112 hatchback with an 1. 6L SOHC engine and deluxe trim.

Since estrogen circulating in the blood can negatively feed-back to reduce circulating levels of FSH and LH, most oral contraceptives contain a synthetic estrogen, along with a synthetic progestin.

Since stratospheric ozone is produced by solar UV radiation, one might expect to find the highest ozone levels over the tropics and the lowest over polar regions.

( Since Phe is necessary for the synthesis of many proteins, it is required for appropriate growth, but levels must be strictly controlled in PKU patients.

Since the Heisenberg principle limits the precision of any measurement of the combination of an electron's momentum ( related to energy ) and its position, in a crystal effectively the available energy levels form a continuous band of allowed energy levels.

Since the mid-1990s, commercial travel on Uzbekistan ’ s portion of the Amu Darya has been reduced because of low water levels.

Since controlled burns are often done during relatively high humidity levels ( on the grounds that they could not be safely contained during periods of very low humidity ), the driptorch is more effective and more often used.

: Since the 1950s, both the atmospheric CO < sub > 2 </ sub > level and obesity levels have increased sharply.

Since outside temperatures can possibly range from-40 ° C (- 40 ° F ) to 46 ° C ( 115 ° F ), with varying degrees of solar loading, along with humidity levels ranging from below 10 % up to 100 %, significant environmental stresses within the enclosure or facility can be produced.

Since the ozone layer absorbs UVB ultraviolet light from the sun, ozone layer depletion is expected to increase surface UVB levels, which could lead to damage, including increase in skin cancer.

For most bands and most small-to mid-size venues ( e. g., nightclubs and bars ), standard bass guitar speaker enclosures or keyboard amplifiers will provide sufficient sound pressure levels for onstage monitoring. Since a regular electric bass has a low " E " ( 41 Hz ) as its lowest note, most standard bass guitar cabinets are only designed with a range that goes down to about 40 Hz.

Since then the Green Party of the U. S. has claimed electoral victories at the municipal, county and state levels.

Since vertical mixing is increasing, and light levels are falling as winter approaches, these blooms are smaller and shorter-lived than their spring equivalents.
