Detection and location of metallic objects imbedded in nonmetallic structures
Small battery operated eddy current proximity measuring device detects and locates metal objects the size of a dime at distances up to one foot within nonmetallic structures. This device weighs approximately two pounds, occupies approximately 60 cubic inches, and is battery powered
Экспериментальные и расчетные величины стандартной энтальпии образования арсенатов щелочных и щелочноземельных металлов
Исследованы термохимические характеристики взаимодействия в водной среде хлоридов щелочноземельных металлов с ортоарсенатом натрия
Исследование состава ароматических углеводородов средних фракций нефти Самотлорского месторождения
В работе представлены результаты исследования состава ароматических углеводородов 1-й группы, входящих в состав керосинонгазойлевой фракции (200-300° С) самотлорской нефти. Для исследования были применены методы жидкостной хроматографии, четкой ректификации, УФ- и ПК-спектроскопии. Установлено, что в состав ароматики 1-й группы входят моно-, ди- (-и -м-изомеры), три- (1, 2, 3- 1, 2, 4- и 1, 3, 5), тетра (возможно всех трех типов замещения, а также пентазамещенные бензола

El uso de Internet en las bibliotecas del CSIC
En este artículo nos proponemos hacer una reflexión sobre el efecto que ha tenido Internet en el panorama bibliotecario del CSIC (Consejo Superior de Investigaciones Científicas). Para ello es necesario hacer referencia al importante proceso de informatización que se ha operado en los 10 últimos años en las bibliotecas del CSIC y que hoy nos permite poder hablar de una red de bibliotecas consolidada
Qualification and testing of CT systems
This chapter focuses on system verification and conformance to specifications. System qualification is carried out to ensure that the system and its components achieve the best performance-usually corresponding to the specifications made by the manufacturer. Acceptance and reverification testing are undertaken on the overall integrated system to check whether the system performs as specified
Steps In the Right Direction: The Pursuit of Walkability Within the United States
The benefits associated with walkability are well documented and observed across a number of disciplines. Benefits pertaining to the economy, physical and mental health, and safety are clearly associated with walkability and the implementation of walkable design within specific communities. Due to dominant practices pertaining to urban design within the United States and a history of increasingly single-use and low-density zoning, walkability and the use of walking as a form of transportation are rarely utilized to the same extent as similarly developed countries. This paper aims to evaluate the features of walkability related to the aforementioned benefits in order to offer a perspective on what may be further employed within American communities to promote walking and walkable design
