Patient delays in seeking help at the onset of rheumatoid arthritis: the problem, its causes and potential solutions

Rheumatoid arthritis (RA) is a chronic inflammatory disease for which early treatment is vital to limit long term joint damage. However, people often delay in seeking medical help at the onset of RA symptoms. The early interpretation of symptoms and the process of making sense of symptoms impacts on both help-seeking decision-making and self-management. Furthermore, the general public’s perceptions and knowledge of RA may also affect the way that symptoms are interpreted. Examining the psychology behind early symptom interpretation, the barriers to help-seeking behaviour and investigating the public understandings of RA, can help us understand how decisions are made and guide us in developing interventions which encourage people to seek help promptly at the onset of RA

Channelized coplanar waveguide pin-diode switches

Three different types of p-i-n diode, reflective CPW switches are presented. The first two switches are the series and the shunt mounted diode switches. Each has achieved greater than 15 dB of isolation over a broad bandwidth. The third switch is a narrow band, high isolation switched filter which has achieved 19 dB of isolation. Equivalent circuits and measured performance for each switch is presented

Кончина «четвертой власти»: СМИ и создание новостей

The notion of the fourth estate is the ideological foundation of journalism in the West. It implies that journalism is something that fulfils and supports the public interest, and acts as an independent check and balance against the excesses of the state. However, changes in the news production cycle and process and ownership have seen the destruction of the fourth estate in practice. This paper accounts for some of the reasons why the fourth estate cannot be considered as being a functioning mechanism in the current times.Признание журналистики «четвертой властью» является одним из оснований журналистики на Западе. При этом предполагается, что журналистика удовлетворяет и поддерживает общественный интерес и действует как независимый элемент системы демократических сдержек и противовесов. Однако перемены в цикле производства новостей, в имущественных отношениях в сфере СМИ на практике предопределили деструктивный характер современной «четвертой власти». Данная статья рассматривает некоторые из причин утраты функциональности современной «четвертой властью»

Microwave characterization of slotline on high resistivity silicon for antenna feed network

Conventional silicon wafers have low resistivity and consequently unacceptably high value of dielectric attenuation constant. Microwave circuits for phased array antenna systems fabricated on these wafers therefore have low efficiency. By choosing a silicon substrate with sufficiently high resistivity it is possible to make the dielectric attenuation constant of the interconnecting microwave transmission lines approach those of GaAs or InP. In order for this to be possible, the transmission lines must be characterized. In this presentation, the effective dielectric constant (epsilon sub eff) and attenuation constant (alpha) of a slotline on high resistivity (5000 to 10 000 ohm-cm) silicon wafer will be discussed. The epsilon sub eff and alpha are determined from the measured resonant frequencies and the corresponding insertion loss of a slotline ring resonator. The results for slotline will be compared with microstrip line and coplanar waveguide
