Towards a critical heritage studies
Anna Karlström’s article made me think of
the inaugural conference of the International
Association of Critical Heritage Studies held in
Gothenburg in June 2012. At the conference,
heritage scholars and graduate students
gathered from around the world—though
mainly from Britain, Australia, and Sweden—
to discuss key debates in the rapidly
developing, wide-ranging field of heritage.
The location, the University of Gothenburg,
was one of the most prominent sites for the
new research field of heritage, as a platform
for research and graduate education from
about the mid-2000s. The conference was
organized through Swedish, British, and
Australian international collaboration, with
participation by the International Journal of
Heritage Studies. The recent careers of two
of the main organizers—Laurajane Smith and
Rodney Harrison—had seen them circulate
between Australia and Britain, and in Smith’s
case, to Sweden as well.Web of Scienc

Patient doses in chest CT examinations: Comparison of various CT scanners
This paper presents results from study on patient exposure level in chest CT
examinations. CT scanners used in this study were various Siemens and General
Electric (GE) models. Data on patient doses were collected for adult and
pediatric patients. Doses measured for adult patients were lower then those
determined as Diagnostic Reference Levels (DRL) for Europe, while doses for
pediatric patients were similar to those found in published data. As for the
manufactures, slightly higher doses were measured on GE devices, both for
adult and pediatric patients
Missing and Missed: Rehumanisation, the Nation and Missing-ness
The bringing together of two lines of research that have previously been treated separately – namely the missing/missed body of apartheid-era atrocities and the racialised body of the colonial museum – animates this issue of Kronos. Both the skeletons of empire and those of apartheid-era atrocities can be thought of as racialised, and as ‘disappeared’ and missing. Furthermore, both areas are marked by similar lines of enquiry, linked to issues of identification, redress and restoration, often framed through notions of humanisation or rehumanisation. Consequently, these different ‘disciplines of the dead’1 have been brought into collaboration and contestation with each other, with missingness often reproduced through the ways in which the dead have been drawn into grand narratives of the nation and its seeming triumphs over colonialism and apartheid.Notwithstanding their similarities, the racialised body of the colonial museum and the body of more recent conflicts have their own genealogies and literatures. The ‘disappeared’ entered the political lexicon of terror largely through Argentina and Chile; two decades later Rwanda and Bosnia turned international attention to mass violence and genocide as exemplified by the mass grave. South Africa slips through these grids: apartheid security forces tried but failed to emulate their Latin American counterparts in ‘disappearing’ activists on a large scale, while inter-civilian violence, which mostly took the form of political rather than ethnic, racial or religious cleansing, did not produce mass graves. Nonetheless, both ‘disappearances’ and inter-civilian conflict produced missing persons in the South African conflict – most presumed dead, and thus, as Madeleine Fullard describes them (this issue) ‘in limbo – dead, but missing.’ Investigations into such cases, led first by the country’s Truth and Reconciliation Commission (TRC), and later by its Missing Persons Task Team (MPTT), sought to locate, exhume, identify and return mortal remains to their families. In so doing, South Africa joined a growing list of countries following this route
Expenditure aspects of construction of new sacral facilities
The graduation thesis-university studies, partially elaborated as a pricing report, is dealing with new churches built in Slovenia in years from 1980 to 2012 and presents various options of value calculations of new churches, with an emphasis on cost-value. The first part of the graduation thesis presents circumstances, demography with emphasis on religious composition of society in Slovenia, the economic situation in the past decades and other outside influences that have been promoting or inhibiting the development of the real estate market, in this case primarily the market of construction of new churches. The work contains explanations of basic concepts, for example different valuation methods, in particular on the cost approach and the aging of the facility. Furthermore relevant expert terms are explained and calculations are made. The thesis presents some German regulations, such as ImmoWertV, WertR, NHK and DIN 276, regulating the valuation of real estate with rules of cost approach. A few examples of calculations are made in order to facilitate reader's understanding. Also Slovenian regulations and practices are presented and illustrated also through use in some calculations. Two methods are specifically exposed, namely the method used by the well established civil-engineering portal PeG and the mass pricing method, which has been used also by GURS. In the main part of the thesis all the churches built in Slovenia between 1980?2012 are briefly presented (it is possible that some of the churches are not mentioned). 16 new built churches (and one church for which plans exist already), were measured and listed. On the basis of this a model for a typical church built in Slovenia in this period is made. Furthermore, financial data of construction of three churches and a few data of equipment and art prices are collected. On the basis of collected data a calculation is made of estimated costs of a typical model of a church built in the territory of Slovenia in the last three decades. All calculated values are compared to each other

Air kerma to HP(3) conversion coefficients for exp osure of the human eye lens to the selected standard X-RAY beam qualities
International Commission on Radiological Protection (ICRP) has decreased the annual dose limit for the eye lens from 150 mSv down to 20 mSv for occupational exposures. The operational quantity Hp (3) has been defined for eye lens dosimetry, while cylindrical phantom approximating the shape of a head was suggested for calibration purposes. The aim of the work was to provide a set of conversion coefficients that could contribute to improving the overall quality of eye lens dose assessment. The work investigated the air kerma to Hp(3,iota)conversion coefficients, Hp(3,iota)/Ka (in Sv/Gy), based on Monte Carlo simulations for a standard beam qualities, different angulations and suitable cylindrical phantom. For incident angles iota from 0(o\) to 90(o)., the conversion coefficients Hp(3,iota)/Ka were in the range 0.44-0.88 for N-40, 0.72-1.06 for N-60, 0.91-1.63 for N-80, 1.08-1.52 for N-100, 1.22- 1.62 for N-120 and 0.14-1.56 for N-150 beam quality. The conversion factors Hp(3)/Ka provided in this work are related to standard beam qualities readily available in the calibration laboratories and are suitable for application in numerous workplace situations in medicine and industry.3rd International Conference on Radiation and Applications in Various Fields of Research (RAD), Jun 08-12, 2015, Budva, Montenegr

Skin dose mapping in interventional cardiology
Interventne kardiološke procedure su često povezane sa relativno visokim dozama i sa dugim vremenom izlaganja zračenju, što često rezultuje visokom apsorbovanom dozom kože. Cilj ovog rada je da se razvije aplikacija za mapiranje maksimalne doze kože u interventnim kardiološkim procedurama. Maksimalna doza na površini kože je izračunata pomoću informacija iz DICOM fajlova generisanih nakon kardioloških procedura. Izračunate maksimalne doze su validirane pomoću XR-RV3 Gafchromic filmova koji su postavljeni ispod pacijenta tokom svake procedure. Srednja devijacija između izmerenih i izračunatih maksimalnih doza je 8,7% ± 26,3%. Simulirana dozna mapa pacijenta je pokazala dobro poklapanje sa XR-RV3 Gafchromic filovima. Aplikacija za mapiranje doze kože prikazana u ovom radu je elegantno rešenje i pogodna alternativa za XR-RV3 Gafchromic filmove.Interventional Cardiology (IC)procedures are frequently associated with relatively high dose rates and prolonged irradiation times, which often results in very high absorbed skin doses. Objectiveof this work is to develop skin dose mapping application for Peak Skin Dose (PSD) estimation in Interventional Cardiology procedures. PSD was calculated using necessary information from Digital Imaging and Communications in Medicine (DICOM) headers generated after cardiac procedures. Calculated PSDs were validated using XR-RV3 Gafchromic films placed under the patient‘s back during each procedure. The mean deviation between measured and calculated PSD was 8.7% ± 26.3%. Simulated skin dose map showed good matching with XR-RV3 Gafchromic film. Skin dose mapping application presented in this paper is elegant solution and suitable alternative to XR-RV3 Gafchromic film.Proceedings: [http://vinar.vin.bg.ac.rs/handle/123456789/8681]XXX симпозијум ДЗЗСЦГ (Друштва за заштиту од зрачења Србије и Црне Горе), 2- 4. октобар 2019. године, Дивчибаре, Србиј
