The detailed physics of the light–matter interaction will of course also depend on the structure of the irradiated molecule, but whatever its identity, certain general features of the excitation of atoms and molecules by ultrafast laser photons have emerged from pioneering studies by research groups through- out the world. First to respond to the laser field are the lighter electrons, which do so on a time scale of attoseconds (a thousandth of a femtosecond): depending upon the intensity of the incident light, the one or more photons absorbed by the molecule either promote an electron to a high-lying energy state of the molecule, or the electron is removed from the molecule altogether, leaving a positively charged ion; at very high intensities multiple electron excitation and ionisation through various mechanisms can occur. Over a far longer time scale of tens or hundreds of femtoseconds, the positions of the atomic nuclei within the molecule rearrange to accommodate the new electrostatic interactions suddenly generated as a result of the new elec- tronic state occupancy prepared by the ultrafast laser pulse: the nuclear motions may involve vibrations and rotations of the molecule, or the mole- cule may fall apart if the nacent forces acting on the atoms are too great to maintain the initial structural configuration. In addition, at high incident intensities, the electric field associated with the laser beam distorts the electrostatic forces that bind the electrons and nuclei in a molecule to such an extent that the characteristic energy levels of the molecule are modified during the ultrashort duration of the laser pulse. Each of the above phenomena is the subject of intensive research pro- Laser snapshots of molecular motions 3 grammes in its own right. A similar series of events, with due alteration of the details, occurs in molecules exposed to intense laser light. From careful measurements of such processs, it is possible to develop quantitative models to describe the molecular dynamical response to impulsive laser excitation. These enable the fundamental interaction of intense, ultrafast laser light with molecules to be understood from first Laser-distorted atomic electron Ponderomotive potential electron trajectory High harmonic photon emission Tunnel ionisation Figure 1. A sequence of events following the interaction of an intense, ultrafast laser pulse with an atom. The potential energy structure of the electron, which would otherwise be symmetric either side of a minimum, thereby confining the electron to the vicinty of the atomic nucleus, is distorted by the incident laser radiation.

Common mistakes in referral letters Letter fails to provide sufficient details to enable the receiver to prioritise the referral order 250 mg cephalexin visa. Client contact details are incomplete or out of date so it is difficult to notify the client about appointments buy cephalexin 250mg without prescription. Important information relating to the client is omitted buy 500 mg cephalexin mastercard, for example the client requires an interpreter or hospital transport cheap 500mg cephalexin mastercard. Letter in reply to a complaint – key content ° Name generic cephalexin 500 mg on-line, address and identification details of complainant. Common mistakes in letters about complaints The letter is written defensively – the clinician attempts to demonstrate his or her expertise using jargon, technical terms and excessive clinical detail. For example, it is not ap­ propriate to include information about a lack of previous complaints about a health worker or a service. Reports Clinicians regularly write clinical reports about specific clients. These are formal written accounts that are functional in nature rather than creative – the writer being required to adhere to certain recognised practices in the organisation and presentation of such material. Format of reports Reports have a basic structure consisting of: ° a title ° an introduction LETTERS AND REPORTS 83 ° the main section ° the conclusion ° actions ° recommendations. Title This tells the reader, at a glance, the subject matter of the report. Introduction The introduction in a report sets the scene for the reader, and makes clear the purpose of the report. It will always include specific information about where, when and why the report writer saw the client. A statement about the source of the information can also be included at this point in the re­ port, for example observations made during direct contacts with the client, information from notes, discussion with the client’s family or liaison with other professionals. These details will help identify for the reader how and at what point the report links in with the total care for that particular client. It is also use­ ful if the report is to be an accurate account for future reference. In some circumstances it may be appropriate to give some background information in the introduction, for instance a brief account of the nature and length of the contact with the client. The emphasis is on brief, with the main points expressed in no more than one or two sentences. A sub­ stantial description is better placed in a separate section under a heading like ‘Background Information’ or ‘Other Relevant Information’. Notes about any limitations on the scope or depth of a report are also placed in the introduction (Inglis and Lewis 1982), for example if an as­ sessment was incomplete due to the late arrival of the client. Main section Most of the information contained within a report is recorded within the main section. The content usually relates to current actions, but may refer to past or future events. It is therefore important to indicate the point in time to which the information relates, for example, ‘in his previous assess­ ment on …’. It is not the place to regurgitate lines from the main body of the text, nor should it contain any new pieces of information. The writer must draw together the key mes­ sages of the report and convey these as concisely as possible. The reader will then be able to extract the key points and significant outcomes. Actions and recommendations are usually listed at the end of the re­ port. Actions The writer needs to make clear what actions he or she has taken or is plan­ ning to take. They are most likely to be about: ° arranging further investigations ° referral to other services ° initiating intervention ° future management of the client (for example date when client needs to be reviewed). These need to be written in the form of specific statements that answer questions like what, why, where, when and how?

At the average purchase 250mg cephalexin otc, comfortable walking speed of people without impairments (about 80 meters per minute) buy discount cephalexin 500 mg on line, the body consumes roughly four times the energy used at complete rest (Ker- rigan generic cephalexin 750 mg without a prescription, Schaufele buy cephalexin 250 mg with mastercard, and Wen 1998 buy cephalexin 250 mg fast delivery, 168). Walking faster and running demand more energy, but so does walking slowly—for muscles and other struc- tures to provide additional balance. At their respective, comfortable walk- ing speeds, people with and without walking difficulties expend about the same energy during the same amount of time. Therefore, people with mobility problems con- sume more energy while walking the same distance than do others. Efforts to avoid pain typically distort smooth COM movement, increas- ing the energy required to walk a given distance. Keeping joints stiff be- cause of pain requires more energy to swing the limbs forward. Typically, people with hip arthritis avoid bearing weight on their painful joint, re- ducing the stance phase on that side. Lurching their trunk toward the af- fected hip, often by dipping their shoulder on that side, they move the COM over the joint, decreasing stresses on it. During the swing phase, people flex their hip slightly, and they avoid jarring and painful heelstrikes. Abnormalities of nerves or their communication with muscles can im- pair gait, sometimes also by distorting patterns of COM movement. Prob- lems with coordination can cause staggering, lunging gait, with legs placed wider apart than normal. People with strokes involving one side of their brains frequently have a “hemiplegic gait. To walk the same distance, people with hemiplegic gaits consume 37 to 62 percent more en- ergy than those without gait problems (Kerrigan, Schaufele, and Wen 1998, 170). Eventually, many people learn to walk well with pros- theses, artificial or mechanical legs (Leonard and Meier 1998). People with amputations on one side typically walk faster with prostheses than those with bilateral amputations, whose slower speed demands more energy. Persons with below-the-knee amputations generally ambulate more easily with prostheses than those with amputations above the knee. Maintaining the health of the stump (skin in- tegrity, in particular) is crucial. Walking depends on many important factors beyond lower-extremity functioning, including people’s cognitive status and judgment, vision, other problems affecting balance (such as vestibular or inner ear function), upper-body strength and mobility, global physical endurance and fitness, and overall health. People with mobility difficulties are more likely than others to report vision problems, dizziness, imbalance, and poorer overall health (Table 3). Biomechanical problems, such as worn or inflamed knee or hip joints, compressed nerve roots exiting the spine, and collapsed or shifted vertebrae, typically cause pain. Pain can develop slowly and insidi- ously or appear suddenly and relentlessly. It can be all-consuming, keeping people awake at night, preventing even the most trivial-appearing activi- Sensations of Walking / 27 table 3.

Stella Richards retired early from her secretarial job when a back problem, spondylolisthesis, laid her out flat for almost six months. If I went into the bathroom, I just had time to wash my hands and hobble back to the bed. If I was in there to go to the bathroom, I could never stay long enough to brush my teeth. People with arthritis often describe immobilizing and painful stiffness, especially on awaking in the morning or after prolonged sitting. Like the tin woodsman from The Wizard of Oz after a rainfall, they feel rusted in place, painfully unable to flex, bend, or move. Jimmy Howard, in his late forties, feels “like somebody’s in there with a hammer and a chisel, just chiseling away. Then one day I was walking, and, whoa, it really started—excruciat- ing pain. I’d be in the supermarket, and I’d have to grab onto peo- ple I don’t know.
