INTRODUCTION The orthodontic technique favored by a clinician frequently determines how a deep curve of Spee (COS) is leveled. The primary purpose of this investigation was to confirm radiographically the long-term effectiveness of a continuous archwire technique--the Alexander discipline--in leveling the COS in patients with Class II Division 1 deep-bite malocclusions treated without extractio...

OBJECTIVE To develop and test the reliability of a case-leveling framework for assigning level of difficulty of the pharmacist's task for initial medication assessments conducted by pharmacists integrated into family physician offices. DESIGN Descriptive study. SETTING Seven family practice sites in Ontario from June 2004 to July 2006. PATIENTS Patients referred by their family physician ...

Advanced techniques of multi-temporal InSAR (MT-InSAR) represent a valuable tool in ground subsidence studies allowing remote investigation of the behavior of mass movements in long time intervals by using large datasets of SAR images covering the same area and acquired at different epochs. The settlement in Beijing is very serious, producing adverse environmental impacts. Excessive groundwater...

In this paper we present preliminary results on the applicability of differential SAR interferometry to detect and measure land movement in the vegetated areas where only few targets or small areas maintain coherence. Strong temporal decorrelation in the vegetated areas makes traditional DINSAR impracticable and, therefore, techniques that are based on phase values of single pixels and long tim...

Manna and Chaudhuri (Eur. J. Oper. Res. 171(2):557–566, 2006) presented a production-inventory system for deteriorating items with demand rate being a linearly ramp type function of time and production rate being proportional to the demand rate. The two models without shortages and with shortages were discussed. Both models were studied assuming that the time point at which the demand is stabil...

Hard metals are an important material due to their specific properties, such as high degree of hardness and resistance to abrasive wear, and they are in wide use today. There are indications that hard metal aerosols can endanger human health. Discussions are ongoing as to how to categorize hard metals as hazardous as a result. This categorization will require deciding in particular how to deter...

— This paper investigates intermediate input effects and labor pooling in the context of urban informality, examining the handicraft industry of Nairobi, Kenya. The paper tests if conditions found in informality interfere with transition pathways in production clusters. 102 semi-structured interviews were conducted with industry participants, including 69 production firms. Findings confirm the ...
