Introduction In 2018 the online NHS111 service was introduced in response to increasing and unsustainable demand for telephone service. We explored user staff perspectives of understand awareness acceptability service, how is used it may affect Methods data from national survey two areas. also undertook semi-structured interviews with 32 recent users 16 stakeholders sites. analysed 3728 795 SPS...
Using helium atom scattering, we have studied the structure and dynamics of a graphene layer prepared in situ on a Ni(111) surface. Graphene/Ni(111) exhibits a helium reflectivity of ∼20% for a thermal helium atom beam and a particularly small surface electron density corrugation ((0.06 ± 0.02) Å peak to peak height). The Debye-Waller attenuation of the elastic diffraction peaks of graphene/Ni(...
The formation of nano-islands on both a Ge(111)-c(2 × 8) surface and an Ag/Ge(111)-(√3 × √3) surface evaporated with 0.1 ML Ni was investigated by scanning tunneling microscopy (STM). We have noticed that at temperatures lower than 670 K, the reaction between Ni and the individual substrate surfaces proceeds to form different structures: flat-topped islands with a 2√7 × 2√7 or a 3 × 3 reconstru...
در این مقاله تاثیر دما و زمان اتصالدهی بر ریزساختار اتصال فاز مایع گذرای سوپرآلیاژ پایه نیکل GTD-111 مورد مطالعه و بررسی قرار گرفته است. فرایند اتصالدهی در دماهای1080، 1120 و °C1160 در زمانهای مختلف انجام گردید و ریزساختار نواحی مختلف اتصال توسط میکروسکوپ نوری و الکترونی روبشی مورد بررسی و تحلیل قرار گرفت. نتایج نشان داد که با افزایش دمای اتصالدهی از 1080 تا °C1160، زمان انجماد ...
Polycyclic aromatic hydrocarbons (PAHs) are immunotoxicants in fish. In mammals, phase I metabolites are believed to be critically involved in the immunotoxicity of PAHs. This mechanism has been suggested for fish as well. The present study investigates the capacity of immune organs (head kidney, spleen) of rainbow trout, Oncorhynchus mykiss, to metabolize the prototypic PAH, benzo [a]pyrene (B...
Anxiety disorders related with central and autonomic stressregulation systems insufficiency. The broad range of anxiety symptoms includes among others signs of neuroendocrinological stress-control faulty. The inherent psychological traits of anxiety are genetically predetermined and can be assigned by the physiological measurements of HRV, QEEG and ERP, which can be used as functional biomarker...
