These measurements helped determine how the particles got their energy and how they were transported through Jupiter's magnetosphere.

These philosophers believed that other elements ( except ether ) were physically palpable and hence comprised minuscule particles of matter.

These particles can hit the Earth within 15 minutes to 2 hours of the solar flare.

These so-called " whistler " mode waves can interact with radiation belt particles and cause them to precipitate onto the ionosphere, adding ionization to the D-region.

These clouds would have a typical density of 30 particles per cubic centimeter.

These particles, or chondrules, are composed mostly of silicate minerals that appear to have been melted while they were free-floating objects in space.

These force carrier particles are strings with endpoints that confine them to their p-branes.

These particles cannot be filtered out before injection, and will accumulate in the body over time, especially in the lungs and eyes, producing various complications such as pulmonary hypertension, an irreversible and progressive disease.

These small particles or organisms gain entry when the shell valves are open for feeding or respiration.

These α subunits are controlled by binding to " cap " structures or regulatory particles that recognize polyubiquitin tags attached to protein substrates and initiate the degradation process.

These force-carrying particles are virtual particles and, by definition, cannot be detected while carrying the force, because such detection will imply that the force is not being carried.

These decay events obey the various conservation laws, and as a result, pairs of particles can be generated so that they are in some specific quantum states.

These reactions occur at far higher energies than with non-ionization radiation, which requires only single particles to ionize.

These strings can oscillate, giving the observed particles their flavor, charge, mass and spin.

These high-priority agents pose a risk to national security, can be easily transmitted and disseminated, result in high mortality, have potential major public health impact, may cause public panic, or require special action for public health preparedness.

These facts pose serious difficulties in many developing nations where the presence of mines hampers resettlement, agriculture, and tourism.

These effects are dose-dependent, and in many cases severe enough to pose the risk of ulcer perforation, upper gastrointestinal bleeding, and death, limiting the use of NSAID therapy.

These still pose problems for superconducting applications but are improving over time.

These tend to attract bird populations, which can pose a hazard to aircraft in the form of bird strikes.

These pose a collision hazard in the narrow and shallow strait.

These observations pose a challenge to current theories of lightning, especially with the discovery of the clear signatures of antimatter produced in lightning.

These offenders tend to be career criminals with histories of violence or whose instant offense ( s ) pose a significant threat to public safety.

These flags became an international symbol of solidarity with this statementNION's " Statement of Conscience ", drafted in spring 2002, first lists a series of criticisms of the Bush Administration and ( secondarily ) the U. S. Congress and calls on the people of the U. S. "... to resist the policies and overall political direction that have emerged since September 11, 2001, and which pose grave dangers to the people of the world.

These monkeys may also pose a biting hazard to tourists ( especially small children ) as they can be quite territorial.

These establishments pose problems of access, safety and are often deprived of water supply networks.

These situations do not inherently pose hazards to the execution of instructions.

These are all anatomical adaptations to vertical hanging and swinging locomotion ( brachiation ), as well as better balance in a bipedal pose.

These morphological differences pose no health risk, and are simply a difference in form.

These risks are typically evaluated by a governmental office ( for example, in a US Government RFP ) to determine whether the risks pose a substantial advantage to the private organization over the competition or will decrease the overall competitiveness in the bidding process.

These backlogs pose risks to the market ( both in theory and in all likelihood ), and they exacerbate other risks in the financial system.

These pose threats to the local animals, especially birds, whose skeletons are frequently found with plastic in the stomach cavity.

These eruptions often cause massive lahars ( mud and debris flows ), which pose a threat to human life and the environment.

These feline anthropomorphic figures may range from a human figure with slight jaguar characteristics to depictions of shamanistic transformations in the so-called transformative pose, kneeling with hands on knees, to figures that are nearly completely feline.

These predators pose little threat to the nimble, non-nesting adults, but certain smallish and agile birds of prey do, especially the American Kestrel ( Falco sparverius ) and Cooper's Hawk ( Accipiter cooperii ), and the Sharp-shinned Hawk ( A. striatus ) and screech owls ( Megascops ).

These swiftlets can pose major identification problems where several species occur.

These poisonous toads pose a significant threat to the northern quoll, which may die after consuming one.

The result of the monumental BMI study were echoed by a 1979 French GEPAN report which stated that about a quarter of over 1, 600 closely studied UFO cases defied explanation, stating, in part, " These cases … pose a real question.

These reduced gravitational effects also pose poorly understood occupational health problems for space crews ranging from space adaptation syndrome to long-term hormonal changes.
