The sequencing of the bovine genome and development of mass spectrometry, in conjunction with flow cytometry (FC), have afforded an opportunity to complete the characterization of the specificity of monoclonal antibodies (mAbs), only partially characterized during previous international workshops focused on antibody development for livestock (1991,(More)
This paper proposes a line search numerical algorithm for Maximum Power Point Tracking (MPPT) in Wind Energy Conversion Systems (WECS). The algorithm maximizes the captured power objective function constructed via a mechanical acceleration estimator with no wind speed measurement necessary. Simulation results are included with varying wind profile, speed(More)
Bovine tuberculosis (bTB) is a major world-wide health problem that has been difficult to control, due to the lack of an effective vaccine and limited ability of the tuberculin skin test (TST) and the ancillary whole blood interferon-gamma (IFN-γ) release assay (IGRA) to detect all infected animals. A 6 h cytokine flow cytometric IFN-γ (CFC) assay was(More)
Although buffaloes (Bubalus bubalis) are a major component of the livestock industry worldwide, limited progress has been made in the study of the mechanisms regulating the immune response to pathogens and parasites affecting their health and productivity. This has been, in part, attributable to the limited availability of reagents to study immune responses(More)
This paper discusses the rotor speed tracking loop configuration in maximum power point tracking (MPPT) in wind energy conversion system (WECS). A new loop configuration is proposed in which the aerodynamic torque is treated as an external disturbance. Internal model control and minimum variance control are used to achieve full disturbance rejection and(More)
Bovine tuberculosis (bTB) caused primarily by Mycobacterium bovis continues to cause significant losses in the cattle industry and is a major public health problem. Despite its worldwide application, the IFN-γ assay has not been applied in Egypt. The aim of this study was to determine the appropriate cut-off value of IFN-γ assay to complement the skin test(More)
Phylogenic comparisons of the mononuclear phagocyte system (MPS) of humans and mice demonstrate phenotypic divergence of dendritic cell (DC) subsets that play similar roles in innate and adaptive immunity. Although differing in phenotype, DC can be classified into four groups according to ontogeny and function: conventional DC (cDC1 and cDC2), plasmacytoid(More)
