Covering stack of layers consisting of a single layer: Local near-surface buckling instability

  The local near-surface buckling of a material system consisting of a half-space, which is covered by the single layer and half-space materials is elastic within the framework of a three-dimensional linearized theory of stability (TLTS). The equations of TLTS are obtained from the three-dimensional geometrically nonlinear equations of the theory of viscoelasticity by using the boundary form perturbations...

Molecular typing of Avian pathogenic Escherichia coli (APEC) using multiprimer PCR

  A total of 42 Escherichia coli strains isolated from broilers and the halls of growth were examined between the years 2010 and 2011, in order to assess the prevalence of avian pathogenic E. coli (APEC) strains in the West of Romania, where the majority broiler is represented by the imported ones. Multiplex PCR technique was used in order to detect three genes governing the synthesis of...

Influence of vehicle headway irregularity in public transport on in-vehicle passenger comfort

  This paper performs an analysis of the influence of headway irregularity in public transport on the quality of the transport service, in the domain of in-vehicle passenger comfort. The influence of vehicle headway irregularity along a route on the in-vehicle passenger comfort has been analysed on urban bus routes that operate in a mixed traffic flow. Based on the research conducted on 2,800 bus departures,...

Certain morphological features in limb-girdle muscular dystrophies are not shared by polymyositis: Useful diagnostic clues

  Some hereditary myopathies can mimic acquired polymyositis (PM) in particular when they first present in adulthood with a limb-girdle distribution of weakness. The diagnosis is made yet more complex when inflammatory infiltrates attend on muscle biopsy. This is common in certain dystrophies in particular limb-girdle muscular dystrophies (LGMD). For better distinction between the two diseases, histochemical...

Peristalsis in a rotating fluid

  This paper is devoted to the study of peristaltic flow of a viscous fluid in a rotating frame. The governing equations for the flow problem are derived under the long wavelength approximation. The closed form solutions for the stream function and the secondary velocity are obtained. The effects of Taylor number on physical quantities of interest such as the pressure rise per wavelength and the flow rate due...

Efficiency analysis of an induction motor with field-oriented control at a hot rolling mill

  In this paper, the efficiency analysis of an induction motor with field-oriented control (FOC) at a hot rolling mill in South Africa is presented. It is shown that the energy consumption of an induction motor at a hot rolling mill can be improved with the introduction of FOC with a variable input reference compared to direct torque and flux control (DTC) with a fixed input reference. An overview on the...

Community engagement in landslide risk assessment in Limbe, Southwest Cameroon

  This paper presents preliminary findings on community engagement in landslide risk assessment and inventory mapping in Limbe, Southwest Cameroon. Emphasis was placed on collection of disaster experiences, training and skills development of the locals in identifying and characterising landslides and landslide contributory factors. Despite a number of challenges ranging from lack of incentives, proper...
