Hazelwood : A school for children and young people, aged 2 to 18, who areblind and deaf – “dual sensory impaired”. <strong>Architect</strong>urally, it is a new type ofproject. Many of the school‟s children are physically handicapped and allhave a degree of cognitive impairment. Together they represent the mostacutely disabled children on the city of Glasgow‟s education role. They willneed lifetime support. I was determined to create a school which wouldsupport the needs of the children and the aspirations of their parents, aplace of safety and ambition that would free the teacher and inspire thechild.Hazelwood School has been a real success. The children and young peoplerespond well to their new environment and appear to be thriving. They aresupported by committed teachers in a bespoke school that their parentslove and take ownership for. The building has received multiple national andinternational awards and I am delighted and humbled by the response to it.
erowe on DSK5CLS3C1PROD with CFRFood and Drug Administration, HHS § 1020.31section. For systems that allowchanges in the SID, the SID indicationspecified in paragraphs (f)(4)(ii) and(f)(4)(iii) of this section shall be themaximum SID for which the beam-limitingdevice or aperture is designed.(iii) Each image receptor support devicemanufactured on or after November1, 1977, intended for installation ona system designed for mammographyshall have clear and permanent markingsto indicate the maximum imagereceptor size for which it is designed.(4) Other x-ray systems. Radiographicsystems not specifically covered inparagraphs (d), (e), (f)(2), (f)(3), and (h)of this section and systems covered inparagraph (f)(1) of this section, whichare also designed for use with extraoralimage receptors and when used with anextraoral image receptor, shall be providedwith means to limit the x-rayfield in the plane of the image receptorso that such field does not exceed eachdimension of the image receptor bymore than 2 percent of the SID, whenthe axis of the x-ray beam is perpendicularto the plane of the image receptor.In addition, means shall be providedto align the center of the x-rayfield with the center of the image receptorto within 2 percent of the SID,or means shall be provided to both sizeand align the x-ray field such that thex-ray field at the plane of the image receptordoes not extend beyond any edgeof the image receptor. These requirementsmay be met with:(i) A system which performs in accordancewith paragraphs (d) and (e) ofthis section; or when alignment meansare also provided, may be met with either;(ii) An assortment of removable,fixed-aperture, beam-limiting devicessufficient to meet the requirement foreach combination of image receptorsize and SID for which the unit is designed.Each such device shall haveclear and permanent markings to indicatethe image receptor size and SIDfor which it is designed; or(iii) A beam-limiting device havingmultiple fixed apertures sufficient tomeet the requirement for each combinationof image receptor size and SIDfor which the unit is designed. Permanent,clearly legible markings shall indicatethe image receptor size and SID641for which each aperture is designed andshall indicate which aperture is in positionfor use.(g) Positive beam limitation (PBL). Therequirements of this paragraph shallapply to radiographic systems whichcontain PBL.(1) Field size. When a PBL system isprovided, it shall prevent x-ray productionwhen:(i) Either the length or width of thex-ray field in the plane of the image receptordiffers from the correspondingimage receptor dimension by morethan 3 percent of the SID; or(ii) The sum of the length and widthdifferences as stated in paragraph(g)(1)(i) of this section without regardto sign exceeds 4 percent of the SID.(iii) The beam limiting device is atan SID for which PBL is not designedfor sizing.(2) Conditions for PBL. When provided,the PBL system shall function as describedin paragraph (g)(1) of this sectionwhenever all the following conditionsare met:(i) The image receptor is insertedinto a permanently mounted cassetteholder;(ii) The image receptor length andwidth are less than 50 cm;(iii) The x-ray beam axis is within ±3degrees of vertical and the SID is 90 cmto 130 cm inclusive; or the x-ray beamaxis is within ±3 degrees of horizontaland the SID is 90 cm to 205 cm inclusive;(iv) The x-ray beam axis is perpendicularto the plane of the image receptorto within ±3 degrees; and(v) Neither tomographic nor stereoscopicradiography is being performed.(3) Measuring compliance. Compliancewith the requirements of paragraph(g)(1) of this section shall be determinedwhen the equipment indicatesthat the beam axis is perpendicular tothe plane of the image receptor and theprovisions of paragraph (g)(2) of thissection are met. Compliance shall bedetermined no sooner than 5 secondsafter insertion of the image receptor.(4) Operator initiated undersizing. ThePBL system shall be capable of operationsuch that, at the discretion ofthe operator, the size of the field maybe made smaller than the size of theVerDate Nov2008 08:24 Apr 27, 2010 Jkt 220072 PO 00000 Frm 00651 Fmt 8010 Sfmt 8010 Y:\SGML\220072.XXX 220072
