In this paper, observer design for an induction motor has been investigated. The peculiarity of this paper is the synthesis of a mono-Luenberger observer for highly coupled system. To transform the nonlinear error dynamics for the induction motor into the linear parametric varying （LPV） system, the differential mean value theorem combined with the sector nonlinearity transformation has been used. Stability conditions based on the Lyapunov function lead to solvability of a set of linear matrix inequalities. The proposed observer guarantees the global exponential convergence to zero of the estimation error. Finally, the simulation results are given to show the performance of the observer design.

Blackleg disease caused by Phoma lingam is an important disease of oil seed rape (Brassica napus) causing losses up to 95%. The efficacy of microbial antagonists against P. lingam in greenhouse was tested. Serratia plymuthica HRO-C48 and Gliocladium catenulatum J1446 were able to reduce the disease intensity of OSR cotelydones infested with P. lingam at rates 44% and 52% respectively. The reduction of the infestation of the root collar in BBCH14/15 was evaluated as well. Plants treated with a suspension of the antagonists (2 × 105 cfu/plant) and inoculated with either pycnidiospore suspension (2 × 107 cfu/ml) or agar disks grown with P. lingam mycelium, showed a reduced infestation rate of 53% - 93% in the presence of S. plymuthica and 46% - 77% in the presence of G. catenulatum. The efficacy of the antagonist depends highly on their concentration inside OSR seeds. Below 105 cfu/seed no significant difference was recorded between control untreated and infested plants.

Objectives: Diabetes is one of the most challenging health problems in the 21st century that brings a considerable economic burden on worldwide healthcare resources. Indeed, people with diabetes have a higher lifetime healthcare expenditure due to the long-term complications, which include micro and macrovascular complications. This study sought to estimate the frequency of diabetes complications, and to investigate the associated risk factors. Methodology: Data were obtained from the medical records of 2401 diabetic patients followed at the Reference Center of Diabetes and Chronic Diseases (RCD) in Oujda (Morocco) during the period 2006-2011. Results: Our sample of 2401 diabetic patients include 64.7% women. 32% of patients have one or more complications;retinopathy is the most frequent complication (16.8%), followed by nephropathy (12.4%), cardiovascular diseases (5.4%), neuropathy (3.6%) and diabetes foot (2%). Logistic regression in univariate followed by multivariate analysis has showed that age, duration of diabetes and high albuminuria are the major risk factors for the development of diabetic complications in both type 1 and type 2 diabetes. Conclusions: Nearly one third of diabetic patients were affected by at least one diabetic complication;retinopathy is the most common complication in these patients. Strengthening programs to improve diabetes management and to reduce the risk of these complications should be a high priority in order to control the cost of treatment.

PURPOSE. To use visual evoked potential (VEP) testing to determine whether visual deficits are present in children with a history of vigabatrin use. METHODS. Contrast sensitivity and visual acuity were assessed by visual evoked potential testing and compared between 28 children (mean age,4.90± 4.92 years) with seizure disorders who had taken vigabatrin and 14 typically developing children (mean age, 3.14± 1.70 years). Exclusion criteria were heritable eye disease, suspected cortical visual impairment, nystagmus, and prematurity>2 weeks. The effects of the following factors on contrast sensitivity and visual acuity were examined: type of seizure (infantile spasms versus other), ERG result, duration of vigabatrin therapy, cumulative dosage of vigabatrin, and other seizure medications (other versus no other medication). RESULTS. Contrast sensitivity and visual acuity were reduced in vigabatrin- treated children with infantile spasms compared with vigabatrin- treated childrenwith other seizure disorders and typically developing control subjects. The other factors examined had no significant effect on contrast sensitivity or visual acuity, with adjustment for seizure type. CONCLUSIONS. Children with infantile spasms on vigabatrin may have compromised visual function, even in the absence of suspected cortical visual impairment. The children tested in the present study have reduced vision, probably associated with infantile spasms rather than vigabatrin.
