We investigated this study to generate a patient related verification procedure for Rapid Arc treatment plans.. Before we started to generate the verification protocol we investigated measurements to analyse the potential of the MatriXX for unblocked photon arc fields. The MatriXX response showed good agreements between calculated and measured dose distribution for field sizes of 7 cm × 7 cm and 24 cm × 24 cm with a passing rate between 99% and 100%. Higher aberrations were found for smaller field sizes than 7 cm × 7 cm and for larger field sizes than 24 cm × 24 cm. During Rapid Arc verification measurement we measured the whole dose distribution which consists of 177 control points (177 beam directions with different MLC shapes and gantry speeds between each beam direction). 2/177 beams irradiated perpendicular through the MatriXX. In addition a range of control points irradiated near lateral through the MatriXX. The advantage of the MatriXX is cylindrical parallel plate chambers. Our ...
Parents of kids with allergies should use environmental control measures to reduce their childs exposure to allergy triggers. Some are easy to do, but others can be costly or fairly time-consuming.. Talk with your doctor or health care provider about starting with environmental control measures that will limit the allergens and irritants causing immediate problems.. Because allergies develop over time with continued exposure to allergens, the doctor also may suggest taking precautions now so your child doesnt develop new allergies. For example, dust mites might not be a trigger, but could become one with continued exposure - so controlling them now could help prevent them from becoming an allergy trigger.. Here are suggested environmental control measures for different allergens and irritants:. ...

Cecil replies: Maybe its just me, but when I hear somebody go on about revolutionary discoveries, negative high energy, or anything to do with ions (which are what a corona discharge device produces), I make sure Ive got a firm grip on my wallet. Still, one never likes to dismiss things out of hand. We even tested laundry balls, remember? So I sent Jane to rummage through the archives. The assembled research presents the usual inconclusive muddle. Some observations: Air ionization is to todays scientists what magnetism was to medical types in the 19th century. In other words, a possible cure for just about anything. A computer search turned up nearly 400 scientific articles on air ionization, claiming that negative ions do everything from reduce asthma symptoms to improve your mood and enhance childrens learning ability. Yet the methodology of these studies is sometimes suspect. For example, a couple papers claim that daily sessions with a high-output negative ionizer will alleviate seasonal ...
Families of kids with allergies should use environmental control measures that reduce exposure to the childs allergy triggers. Heres how to begin.
The study shows that krypton-85 from nuclear fission enhances air ionization and, thus, interferes with the atmospheric-electrical system and the water balance of the earth atmosphere. This is reason for concern: There are unforeseeable effects for weather and climate if the krypton-85 content of the earth atmosphere continues to rise. There may be a krypton-specific greenhouse effect and a collapse of the natural atmospheric-electrical field. In addition, human well-being may be expected to be impaired as a result of the diminished atmospheric-electrical field. There is also the risk of radiochemical actions and effects caused-by krypton-85-containing plumes in other air-borne pollutants like the latters transformation to aggressive oxidants. This implies radiation smog and more acid rain in the countries exposed. This study summarizes findings gained in these issues by various sciences, analyses them and elaborates hypotheses on the actions and effects of krypton-85 on the air, the atmosphere ...
Consumer Reports, a non-profit US-based product-testing magazine, reported in October 2003 that air ionisers do not perform to high enough standards compared to conventional HEPA filters. The exception was a combination unit that used a fan to move air while ionizing it. In response to this report, The Sharper Image, a manufacturer of air ionisers (among other products), sued Consumers Union (the publishers of Consumer Reports) for product defamation. Consumer Reports gave the Ionic Breeze and other popular units a "fail" because they have a low Clean Air Delivery Rate (CADR). CADR measures the amount of filtered air circulated during a short period of time, and was originally designed to rate media-based air cleaners. The Sharper Image claimed that this test was a poor way to rate the Ionic Breeze, since it does not take into account other features, such as 24-hour-a-day continuous cleaning, ease of maintenance, and silent operation. The United States District Court for the Northern District ...
An appliance is provided for installation within the mouth of an individual to prevent obstruction of the natural airway of the individual and to enhance natural ventilation during sleep. The appliance is hollow and constructed of material which is custom-molded to the user. An external negative air supply is provided which connects to a tube extending from the appliance and draws air from the hollow appliance creating a partial vacuum in the users retroglossal area urging the users tongue and soft palate away from the users posterior pharyngeal wall and thereby opening an airway to the users nasal cavity. A sensor provides control information to the negative air supply by sensing relative pressure in the users oral cavity. The natural breathing cycle is thus facilitated but not controlled by the appliance.

Surfaces of hydrophobic polymers are treated to reduce their friction resistance characteristics when in contact with an aqueous environment by exposing the surfaces to an oxidation treatment, preferably by use of radio frequency glow discharge. This oxidation is followed by exposure to atmospheric air, until there is a substantial reduction in the air-water contact angle of the surfaces. The reduced friction resistance characteristics are important in aqueous applications where there is movement between the surfaces of two polymeric materials, such as in double slideable catheters and similar medical products. This process also provides lower coefficients of friction for general polymeric products in contact with water and aqueous solutions.
An unsolved problem in surgical implantology is the inadequately sealed junction between transcutaneous implants and surrounding skin or soft tissue. This results in reoccurring or chronic peri-implantary inflammation. The purpose of this study was to develop an in-vitro model enabling the examination of adhesion and proliferation of fibroblasts on surface variations of titanium materials. The surfaces employed in this study were polished, sandblasted, glassblasted, collagen-A and silicon coated titanium platelets. Additionally, half of these platelets had been preprocessed with radio frequency glow discharge treatment (RFGDT). Thus, in total ten surface modifications have been involved. Platelets were deposited in wells of a 96 micro-titre plate. Then these wells were filled with nutritive solution and loaded with 1 x 104 fibroblasts (human fibroblasts). Cultivation period was 12 hours for testing cell adhesion and 72 hours for testing proliferation. After being detached from the titanium ...

In the last decade, diverse strategies in surface modification have been applied on implantable biomaterials such as hydroxyapatite (HA) [1], low-density polyethylene (LDPE) [2] and poly(l-lactic-co-glycolic acid) (PLGA) [3] to improve their intended functions in the body. One of the main purposes for surface modification is to enhance or inhibit protein adsorption on the surface of biomaterials. For example, plasma surface-modification (PSM) techniques such as radio frequency glow discharge have been tested to alter the surface functionalities and, therefore modulate protein adsorption [4] and cell adhesion to biomaterials [5]. Higher reproducibility in surface treatment and flexibility to obtain different surface characteristics, such as surface charge [6], energy [7] and chemistry [8] were achieved using PSM.. The interactions between proteins and surface of biomaterials are mainly energetic. In particular, the van der Waals, electrostatic, hydrogen bonding and hydrophobic interactions are ...

This allowed one to use a model based on solution of the Boltzmann equation in the two-term approximation in assumption that the EDF depends on the radial coordinate only through its dependence on the total electron energy (including the potential energy in the radial electric field) 14,15 . Our results demonstrate that applicability of such model to CF4 discharge (at low RN) is quite doubtful. 13Torr).

To further explore the composition and distribution of secondary organic aerosol (SOA) components from the photo-oxidation of light aromatic precursors (toluene, m-xylene, and 1,3,5-trimethylbenzene (1,3,5-TMB)) and idling gasoline exhaust, a vacuum ultraviolet photoionization mass spectrometer (VUV-PIMS) was employed. Peaks of the molecular ions of the SOA components with minimum molecular fragmentation were clearly observed from the mass spectra of SOA, through the application of soft ionization methods in VUV-PIMS. The experiments comparing the exhaust-SOA and light aromatic mixture-SOA showed that the observed distributions of almost all the predominant cluster ions in the exhaust-SOA were similar to that of the mixture-SOA. Based on the characterization experiments of SOA formed from individual light aromatic precursors, the SOA components with molecular weights of 98 and 110 amu observed in the exhaust-SOA resulted from the photo-oxidation of toluene and m-xylene; the components with a ...
There are currently 95 sites in the NAMN - at 59 of these sites, an active diffusion denuder methodology using the CEH DELTA (DEnuder for Long Term Atmospheric sampling) system (where power is available) is used to provide the main spatial and temporal patterns of NH3 across the UK. Aerosol NH4+ is monitored at a subset of DELTA sites. A secondary network of ALPHA (Adapted Low-cost Passive High-Absorption) samplers are employed at a further 49 sites to assess regional and local scale variability in air NH3 concentrations. To provide an ongoing validation of the ALPHA sampler, the method is calibrated against the DELTA method at 12 sites within the network.. ...

The management of OA consists of limiting the workers exposure to the offending agent to amounts that will not induce disease. A number of approaches can be taken. For example, the worker can be moved to another location within the workplace where little or no offending agent is present. Other techniques include using effective equipment to remove dust and vapor exposure and improving workplace ventilation so that frequent air exchange limits agent accumulation. Evaluation of the workplace should be conducted by a trained industrial hygienist who can measure the degree of agent exposure. It is important to remember that levels of exposure below the legal limits are based on toxicity studies and, therefore, the presence of even tiny amounts of sensitizing agents may still cause immunologic reactions. Face masks of the filtering type are not especially efficient or well-tolerated. In contrast, a compressor with a HEPA filter creating a positive air flow through a mask or head piece can markedly ...
I have years of experience experimenting with negative ion generators going back to the late 70s when the most popular model was a small pedestal with "copper fuzz" on top. Heres my opinion:. First, I swear negative ions work to clear the air. I had a girlfriend who smoked a lot, and the -Ion-gen kept the kitchen fairly fresh.. Second, the charged particulates will build up on your walls. When we got tired of trying to clean off the yucky brown stains, we simply hung big sheets of news print on the nearby wall. We could make diagrams and leave notes on the paper, and it was easy to tape up new stuff to protect our walls.. Third, KEEP IT AWAY FROM ELECTRONICS!!! My girlfriend wrecked a stereo system and a fairly expensive Marchant electronic calculator my moving the -Ion-gen too close. Those particles will penetrate any electronics….. Fourth, check out the specs to determine which generators produce more negative ions instead of ozone (O3). O3 is not healthy. Free radicals continually ...
