The development and initial validation of the Drug Abuse Screening Test for Adolescents (DAST-A) is summarized. The DAST-A, derived from a modification of the original adult version called the Drug Abuse Screening Test (DAST: Skinner, 1982), was psychometrically tested in a study group of adolescent inpatients. The DAST-A demonstrated good internal consistency, high test-retest reliability, uni...

We report the use of the organic crystal DAST as a freely propagating electromagnetic-wave sensor at terahertz (THz) frequency. We also report the result of using a DAST crystal as a mid-IR THz emitter. Compared with the optical rectification from our best ZnTe emitter, that obtained by use of DAST demonstrates a sixfold enhancement of radiation at 7-20 THz.

4-N,N-dimethylamino-4'-N'-methyl-stilbazolium tosylate (DAST) is an important optical material, but its poor conductivity limits applications in devices. To tackle this problem, we designed, prepared, and systematically investigated novel binary composite films that are composed of two-dimensional (2D) DAST and 2D graphene. Results indicate that both electrical and optical properties of DAST ca...

This article reviews the reliability and the validity of the (10-, 20-, and 28-item) Drug Abuse Screening Test (DAST). The reliability and the validity of the adolescent version of the DAST are also reviewed. An extensive literature review was conducted using the Medline and Psychinfo databases from the years 1982 to 2005. All articles that addressed the reliability and the validity of the DAST...

This paper describes the design and implementation of DAST, a Distributed Arbitrary Segment Tree structure that gives support of range query for public Distributed Hash Table (DHT) services. DAST does not modify the underlying DHT infrastructure, instead it utilises the scalability and robustness of DHT while providing simplicity of implementation and deployment for applications. Compared with ...

Introduction: Substance use disorder is one of the most critical social problems in Iran. For this disorder, weneed a proper assessment tool based on our indigenous culture. Objective: This study assesses the factor structure and psychometric properties of 10-item and 20-item Persian versions of Drug Abuse Screening Tests (DAST-10 and DAST-20). Materials and Methods: In this cross-sectional s...

Psychometric properties of the Drug Abuse Screening Test (DAST-10) in heroin dependent adults and adolescents with drug use disorder Objective: The psychometric properties of the Drug Abuse Screening Test (DAST-10), developed to screen individuals for drug problems, are evaluated in Turkish patients with drug use disorder. Method: Participants included 100 adolescents with drug use disorder in ...

Using terahertz time-domain spectroscopy, we have measured the index of refraction and the absorption coefficient of the organic ionic salt 4-N, N-dimethylamino-4?-N?-methyl-stilbazolium tosylate (DAST). This promising organic electro-optic material exhibits strong absorption and dispersion for frequencies above 1 THz at both room temperature and 83 K. No reduction in the absorption strength is...

Telephone: b 1 – 604 – 822 5333, c 1 – 604 – 822 6936 Abstract Relying solely upon external ATE resources for scan test in complex SoC designs is increasingly difficult. In this work, we develop the concept and implementation of an Embedded Autonomous Results Analyzer (EARA) to be used in our modified Dedicated Autonomous Scan-based Testing (DAST) methodology. DAST introduces hierarchy and sepa...

INTRODUCTION There is ongoing controversy regarding the appropriate use of narcotic analgesia for patients presenting frequently to the emergency department (ED) with subjective acute exacerbations of pain. "Are we treating pain or enabling addiction?" OBJECTIVES To determine whether the presence of specific factors could be used to identify adults complaining of acute exacerbations of pain f...
