- Acreo has a long tradition of working with quantum structure based infrared (IR) detectors and arrays. This includes QWIP (quantum well infrared photodetector), QDIP (quantum dot infrared photodetector), and InAs/GaInSb based photon detectors of different structure and composition. It also covers R&D on uncooled microbolometers. The integrated thermistor material of such detectors is advantageously based on quantum structures that are optimised for high temperature coefficient and low noise. Especially the SiGe material system is preferred due to the compatibility with silicon technology. The R&D work on IR detectors is a prominent part of Acreo's centre of excellence "IMAGIC" on imaging detectors and systems for non-visible wavelengths. IMAGIC is a collaboration between Acreo, several industry partners and universities like the Royal Institute of Technology (KTH) and Linkoping University. (C) 2010 Elsevier B.V. All rights reserved.

- The aim of this study was to test the inter-rater reliability of a revised oral assessment guide (ROAG) for patients residing in a geriatric rehabilitation ward. A consecutive sample of 140 patients was recruited for the study. Oral assessments were performed for 133 newly admitted patients by one registered nurse (RN) during a period of six months. A dental hygienist (DH) carried out 103 oral assessments during the same half-year. For 66 patients, the RN and the DH performed independent assessments. There was an agreement between the RN and the DH in the majority of the independent assessments, except for tongue and teeth/dentures. The percentage agreement exceeded 80 percent. Inter-rater agreement measured by Cohen's Kappa coefficient ranged from moderate to very good and percentage agreement had a range of 58 to 91 percent. The agreement was highest in assessment of voice and swallowing (91%). Assessments of teeth and dentures seemed to be most difficult for the RN to evaluate. ROAG was found to be a clinically useful assessment tool. Additional education and training is needed to improve the reliability of the oral assessments and should include continuous support from a dental hygienist as well as a pictorial manual on how to use the ROAG.

Living with facial disfigurement- Strategies for individuals and care management

Tidskriftsartikel (refereegranskat)abstract
- Individuals and families affected by craniofacial disorders have expressed dissatisfaction with their experiences in the healthcare system, with day care, and in school situations. To capture their views, focus group encounters were done in a group of young individuals with these disorders and in a group of parents whose children were affected. The aim was to synthesize their attitudes and experiences into improved strategies for parents, teenagers, and professionals in the healthcare system. Their views were compiled into a document that emphasizes the responsibilities of persons with craniofacial disorders and their parents to actively seek information on diagnosis and treatment options and to participate in decisions on therapy. The conclusion was that it is not lack of specific knowledge but rather a lack of implementation of existing recommendations that makes living with facial disfigurement difficult for many individuals and their families. © 2011 Special Care Dentistry Association and Wiley Periodicals, Inc.

- Aagenaes syndrome/lymphedema cholestasis syndrome 1 (LCS1) is a rare genetic disorder characterized by neonatal cholestasis and lymphedema. The aim was to assess dental care and oral health in adults with LCS1. Fifteen (9M, 6F) individuals diagnosed with LCS1, aged 19-59 years participated. The study evaluated salivary secretion rate, dental radiographs, intraoral photos and included a questionnaire. Eight (53%) had regular dental checkups. Three had received subsidized dental care. Seven (47%) had two or more subjective symptoms of xerostomia. Three (20%) had a decreased stimulated salivary secretion rate below 0.7 mL/minute. Seven (47%) had dentin caries. Marginal periodontitis was found in all six patients above 35 years of age, but not before that age. Thirteen (87%) had tooth discoloration, which was extensive in three (20%). Conclusion. Several patients with LCS1 have problems with periodontitis and tooth discoloration. Frequent dental checkups are therefore recommended. © 2014 Special Care Dentistry Association and Wiley Periodicals, Inc.

Notes on the plasma resonance peak employed to determine doping in SiC

- The doping level of a semiconductor material can be determined using the plasma resonance frequency to obtain the carrier concentration associated with doping. This paper provides an overview of the procedure for the three most common polytypes of SiC. Results for 3C-SiC are presented and discussed. In phosphorus doped samples analysed, it is submitted that the 2nd plasma resonance cannot be detected due to high values of the free carrier damping constant gamma. (C) 2015 Elsevier B.V.

- Imaging in the long wavelength infrared (LWIR) range from 8 to 14 μm is an extremely useful tool for non-contact measurement and imaging of temperature in many industrial, automotive and security applications. However, the cost of the infrared (IR) imaging components has to be significantly reduced to make IR imaging a viable technology for many cost-sensitive applications. This paper demonstrates new and improved fabrication and packaging technologies for next-generation IR imaging detectors based on uncooled IR bolometer focal plane arrays. The proposed technologies include very large scale heterogeneous integration for combining high-performance, SiGe quantum-well bolometers with electronic integrated read-out circuits and CMOS compatible wafer-level vacuum packing. The fabrication and characterization of bolometers with a pitch of 25 μm × 25 μm that are arranged on read-out-wafers in arrays with 320 × 240 pixels are presented. The bolometers contain a multi-layer quantum well SiGe thermistor with a temperature coefficient of resistance of -3.0%/K. The proposed CMOS compatible wafer-level vacuum packaging technology uses Cu-Sn solid-liquid interdiffusion (SLID) bonding. The presented technologies are suitable for implementation in cost-efficient fabless business models with the potential to bring about the cost reduction needed to enable low-cost IR imaging products for industrial, security and automotive applications.
