“…An enzyme-linked immunosorbent assay 4/27 (ELISA) based on Vero cells infected with MERS-CoV was initially used to detect neutralising antibodies in camels in SA and positive samples were confirmed by Western blot assays techniques (10). Also, a MERS-CoV antibody ELISA for camels (immunoglobulin G [IgG]) was used to detect specific antibodies in the sera of camels from the Canary Islands (22), as well as from Eastern Africa (23). This latter study reported that the recombinant enzyme-linked immunosorbent assay (rELISA) based on MERS-CoV S1 was 99% specific when correlated with the results of a microneutralisation confirmatory test (23).…”

A cross-sectional study was conducted in five regions in Saudi Arabia (SA) to investigate the epidemiology of Middle East respiratory syndrome coronavirus (MERS-CoV) infection in dromedary camels (Camelus dromedarius) during April and May 2015. Serum and nasal swab samples were tested for MERS-CoV antibodies and ribonucleic acid (RNA) using a recombinant enzyme-linked immunosorbent assay (rELISA) and real-time reverse-transcription-polymerase chain reaction (rRT-PCR), respectively. The overall MERS-CoV antibody seroprevalence was 80.5%, whereas the overall viral RNA prevalence was 2.4%. The associations of risk factors with each prevalence were quantified using univariate and multivariate analyses. The multivariate models identified region, age, grazing system, exposure to wild animals and dung removal as factors significantly associated with seroprevalence (p ≤ 0.05). A higher seroprevalence was more likely to occur in: camels from the Riyadh, Eastern, Northern and Makkah regions than those from the Jazan region; camels ≥4 and 1-3 years of age (marginally significant) than calves <1 year; and camels raised in zero grazing and semi-open grazing systems than those raised in an open grazing system. However, the presence of wild animals and daily dung removal were negatively associated with seroprevalence. On the other hand, region and sex were significantly associated with MERS-CoV RNA prevalence (p ≤ 0.05). A higher viral RNA prevalence was more likely to occur in camels from the Riyadh region and Eastern region (marginally significant) than in those from the Makkah region, and in male camels than female camels. In conclusion, the risk factors identified in this study can be considered to be predictors of MERS-CoV infection in camels and should be taken into account when developing an efficient and cost-effective control strategy.Rev.

“…The rare earth-3d intermetallics have been developed mainly as high-performance permanent magnets for their high uniaxial anisotropy and high saturation magnetization, such as Nd 2 Fe 14 B, SmCo 5 , Sm 2 (Co, Fe) 17 and R(Fe 1−x M x ) 12 [1][2][3]; they have been very widely used in our daily life. The Nd-based ThMn 12 type magnetic materials are also well-studied materials [4][5][6]. However, a large number of rare earth-3d intermetallics with planar anisotropy were considered as useless in the field of permanent magnets and less applied investigations have been done on other fields.…”

The microwave magnetic properties of rare earth–3d intermetallic compounds Nd(Fe1−xCox)10V2 (ThMn12-type, 0 ⩽ x ⩽ 0.5) have been studied. The x-ray diffraction analyses and static magnetic measurements indicate that the anisotropy in this system is strongly modified by Co substitution. With increasing Co content, the easy magnetization direction appears to deviate from the c-axis (x = 0) to the c-plane (x = 0.2, 0.3), and changes back to the c-axis (x = 0.5); the microwave permeability and the resonance frequency of the compounds change with the saturation magnetization and the magnetic anisotropy. Compared with uniaxial compounds, the planar ones have a higher microwave permeability and microwave absorption. Hence, it is possible for them to be utilized in microwave absorbers and other devices that work under high frequencies.
