Recovering evidential data from magnetic tapes in a forensically sound manner is a difficult task. There are many different tape technologies in existence today and an even greater number of archive formats used. This paper discusses the issues and challenges involved in the forensic acquisition and analysis of magnetic tapes. It identifies areas of slack space on tapes and discusses the challe...

We describe a scalable method for producing continuous graphene networks by tape casting surfactant-stabilized aqueous suspensions of functionalized graphene sheets. Similar to all other highly connected graphene-containing networks, the degree of overlap between the sheets controls the tapes' electrical and mechanical properties. However, unlike other graphene-containing networks, the specific...

Three hundred and four new and return paediatric outpatient consultations were tape recorded. Questionnaires (and tapes) relating to the experience were returned from 286 families. They showed that tapes had been helpful to more than 99% of parents and grandparents. The main benefits were in refreshing the memories of those who attended the consultation and in helping the understanding of those...

Abstract High-temperature superconductors (HTSs) enable exclusive operating conditions for fusion magnets, boosting their performance up to 20 T generated magnetic fields in the temperature range from 4 K K. One of main technological issues HTS conductors is focused on protection case thermal runaway (quench). In spite extremely high stability materials, quenching still possible due local defec...

Heat transfer enhancement is the process of increasing heat-transfer coefficient, which enhances system's performance. Enhancing heat a major problem for saving energy and also beneficial economically. Many passive devices are used inside tubes to improve such as twisted tape inserts, rough parts, extended surfaces, additives liquids wire plugs, etc. This research reviewed one most effective in...

Auditory hallucinations are found in patients with schizophrenia. For some patients with persistent psychotic symptoms, hallucinations are unresponsive to medications. We report three cases with schizophrenia and persistent auditory hallucinations. In this study three types of tapes were used: pure music, music and speech, blank tapes. The patients were asked to record the duration and severity...

OBJECTIVE Identification of brain activity associated with craving is important for understanding the neurobiology of addiction. METHOD Brain activity was measured in cocaine addicts and healthy subjects by functional magnetic resonance imaging (fMRI) while the subjects watched videotapes designed to elicit happy feelings, sad feelings, or the desire to use cocaine. The subjects indicated the...
