چکیده
In his Norman Kerr Memorial Lecture on " Drug Addiction " Sir William Willcox said that the commonest cause of addiction in the citizen classes was undoubtedly the prescription of the drug for medical purposes. It was to be feared that after operations drugs were too often given as a routine practice, without sufficient regard to the dangers of toxic action and the development of addiction disease. The continued use of drugs for insomnia was a method of treatment harmful for the cure of the condition, and patients should be led to take that view. The terrors of insomnia were incomparable to those of drug addiction, and a little sleep following natural methods of treatment was of far greater benefit than the more prolonged abnormal sleep produced by narcotic drugs. As to the general lines of treatment the only hopeful method was one which recognised that drug addiction was a disease requiring the same careful attention to detail that any other disease would receive. The general standard of health should be raised to as high a pitch as possible, and any predisposing factors should be dealt with. In that way the prospect of

Investigation of the Relationship between Ultrasonographic Findings and Analyses of Bladder Contents in Cats
Background: Echoes are frequently observed in cat bladder contents through ultrasonography and often mentioned as incidental findings. No comprehensive study has been conducted so far on the precise echoes nature in the bladder contents ultrasonography in cats. OBJECTIVES: The purpose of this study is to provide an accurate description of the cat bladder contents echoes and to specify the relat...
متن کاملApplication of Model-Based Estimation to Time-Delay Estimation of Ultrasonic Testing Signals
Time-Delay-Estimation (TDE) has been a topic of interest in many applications in the past few decades. The emphasis of this work is on the application of model-based estimation (MBE) for TDE of ultrasonic signals used in ultrasonic thickness gaging. Ultrasonic thickness gaging is based on precise measurement of the time difference between successive echoes which reflect back from the back wall ...
متن کاملAn investigation into the effect of magnetic resonance imaging (MRI) echo time spacing and number of echoes on the sensitivity and dose resolution of PAGATUG polymer-gel dosimeter
Background: There are various methods to read out responses of a polymer-gel dosimeter, among which the Magnetic Resonance Imaging (MRI) technique is the most common one. Optimizing imaging protocols can have significant effect on the sensitivity and the dose resolution of polymer gel dosimeters. This study has investigated the effects of the number of echoes (NOE) and the echo time spacing (ES...
متن کاملOn the characteristics of 150-km echoes observed in the Brazilian longitude sector by the 30 MHz São Luı́s radar
We present long-overdue details about the intensity and spectral characteristics of 150-km echoes observed by the São Luı́s radar in Brazil. The São Luı́s observations show that the echoes usually come from multiple scattering layers that descend in altitude before local noon, and ascend during afternoon hours, similar to what has been found in observations made in other longitude sectors. The la...
متن کاملطراحی و ساخت روبشگر فراصوتی جهت تهیه تصاویر روبش B (B-Scan) از قطعات صنعتی
The results of ultrasonic tests are usually displayed as A-scan signals. In an A-scan signal, reflections of ultrasonic wave form different reflectors are shown as sharp echoes on a time by amplitude display. Interpretation of these echoes can sometimes be quite difficult and usually requires knowledgeable and experienced specialists. There exist other methods of displaying the ultrasonic test...
متن کاملEchoes of the Month
Writing in the " Sunday Express " on the Health of 1922, Sir Arthur Griffith-Boscawen says that the recent visitation of smallpox should serve as a warning. " Great Britain, though an island and itself virtually free from smallpox, is in these days of new-fashioned transport in closer touch than ever with overseas countries which have not yet succeeded in stamping out smallpox from their midst....
