The history of treating meniscal lesions has been characterized by firm belief in "radical" surgery, with serious long-term consequences for the individual and society. The menisci play a critical protective role for the knee joint through shock absorption and load distribution. Currently, the consensus in surgical treatment of meniscal tears is to preserve as much functional meniscal tissue as po
It is argued that the vacancy-oxygen (VO) complex (A center) in Ge has three charge states: double negative, single negative, and neutral. Corresponding energy levels are located at E-c-0.21 eV (VO--/-) and E-v+0.27 eV (VO-/0). An absorption line at 716 cm(-1) has been assigned to the asymmetrical stretching vibration mode of the doubly negatively charged VO complex. (C) 2002 American Institute of
In the presence of the nonionic alkyloxyethylene surfactant n-dodecylpentaoxyethylene glycol ether (C12E5), the anionic conjugated polyelectrolyte (CPE) poly{1,4-phenylene-[9,9-bis(4-phenoxy-butylsulfonate)]fluorene-2,7-diyl} (PBS-PFP) dissolves in water, leading to a blue shift in fluorescence and dramatic increases in fluorescence quantum yields above the surfactant critical micelle concentratio
To provide for a high QoS in a cellular network, each call should be assigned to its preferred cell and priority given to already ongoing calls. Herein, a combined speed-sensitive layer selection method and dynamic guard channel scheme, called CLARR, for use in hierarchical networks, is introduced. To reduce the complexity, partially the same speed estimation and measurement procedures are applied
The study of creativity needs a theory of personality as its backbone. Several alternatives are reviewed. Psychoanalysis is deemed unserviceable because of its lack of an integrated theory of perception. A useful theory of personality should be process-oriented and avoid substance concepts like traits. It may still borrow a number of fruitful constructs from its predecessors. One such, often debat
We investigate how model populations respond to stochastic harvesting in a stochastic environment. In particular, we show that the effects of variable harvesting on the variance in population density and yield depend critically on the autocorrelation of environmental noise and on whether the endogenous dynamics of the population display over- or undercompensation to density. These factors interact
Abstract in UndeterminedEmpirical results show that frequently the meaning of expressions used by students in expressing their understanding of subject matter does not correspond to the meaning of those expressions in the subject matter theory that the students are expected to learn. There is also often a lack of identity of meaning between the same students' use of the same expression from one us
Purpose of review To discuss the rationale for various treatment strategies in rheumatoid arthritis with extra-articular manifestations, and to review advances in understanding the impact of extra-articular rheumatoid arthritis and its management. Recent findings Recent epidemiologic studies of extra-articular rheumatoid arthritis manifestations have emphasized their major role as predictors of pr
This paper argues that the poor conceptualization of the "firm" in economic geography detracts from the analytical strengths and policy relevance of the discipline. Identified as a phenotype, the firm remains ambiguous as an analytical category. This paper reviews nine overlapping conceptualizations of the firm in order to identify their relevance to the economic geography project. It discusses th
This paper presents and suggests a load combination factor for moisture induced stress (MIS) when MIS and snow load are combined. It is argued that MIS may be considered as an ordinary load to be combined with other structural actions, for example snow load. This outlook is not new but till now the load combination factor issue has not been investigated. Based on measured snow depths and calculate
