Cervical Radiculopathy: A Study With Selective Nerve Root Blocks

Popular Abstract in Swedish Symtomgivande nervrots påverkan i halsryggen diagnostiseras via sjukhistoria, klinisk undersökning och magnetkamera undersökning av halsryggen (MRI). Hos flera av patienterna som genomgår denna utredning infinner sig svårigheter att identifiera den/de nervrötter som är ansvariga för patientens smärta. Detta beror på att den kliniska undersökningen och undersökningen medCervical radiculopathy is diagnosed by history, clinical examination of the patient and magnetic resonance imaging (MRI) of the cervical spine. In many of the patients undergoing this diagnostic strategy, the nerve root/roots responsible for the radicular pain is difficult to define as clinical examination and MRI investigation does not provide information enough. The information from transforamin

Providing QoS Guarantees in Ad Hoc Networks through EDCA with Resource Reservation

As the use of WLANs based on IEEE 802.11 increase, the need for QoS becomes more obvious. The upcoming IEEE 802.11e aims at providing QoS, but its contention-based medium access mechanism enhanced distributed channel access (EDCA), provides only service differentiation, i.e. soft QoS. In order to provide hard QoS, we have proposed an extension called EDCA with resource reservation (EDCA/RR), which

Power System Security Assessment - Application of Learning Algorithms

The last years blackouts have indicated that the operation and control of power systems may need to be improved. Even if a lot of data was available, the operators at different control centers did not take the proper actions in time to prevent the blackouts. This depends partly on the reorganization of the control centers after the deregulation and partly on the lack of reliable decision support s

Plate end debonding : a modified approach to predict stress in FRP–concrete bond

An important failure mode of RC beams retrofitted with FRP plates is plate end debonding. Design codes provide equations for estimating shear stress at the plate end, but none of these equations include the FRP to concrete width ratio. This paper suggests an improved equation for calculating shear stress that includes the width ratio. The new equation was obtained by fitting 3D nonlinear FEM resul

Patterns of geographic variation in Silene section Elisanthe (Caryophyllaceae): hybridization and migrational history

Large-scale patterns of genetic variation in chloroplast (cp) and nuclear DNA in the widespread European herb species Silene latifolia and S. dioica were investigated using cpPCR-RFLPs, non-coding cpDNA sequences, AFLPs and sequences of the internal transcribed spacers (ITS) of nuclear ribosomal DNA (rDNA). The results of the analyses of cpDNA variation using PCR-RFLPs and non-coding sequence data
