An HPLC or IC front-end has several modules (most often pump, autosampler, column compartment, and sometimes UV detector). Because each module has numerous properties, it is impossible to place all controls on a single panel. Instead they are placed on several module-specific panels. In addition a “Home” panel is provided for an easy overview. The panels are then represented as Tabs on the comp...

This paper proposes a new instrumental variables estimator for a dynamic panel model with …xed e¤ects with good bias and mean squared error properties even when identi…cation of the model becomes weak near the unit circle. We adopt a weak instrument asymptotic approximation to study the behavior of various estimators near the unit circle. We show that an estimator based on long di¤erencing the ...

OBJECTIVE (1) To determine which facial landmarks show the greatest movement during specific facial animations and (2) to determine the sensitivity of our instrument in using these landmarks to detect putatively abnormal facial movements. DESIGN Movements of an array of skin-based landmarks on five healthy human subjects (2 men and 3 women; mean age, 27.6 years; range, 26 to 29 years) were ob...

OBJECTIVE To describe the stages in the cultural adaptation of "The End-Stage Renal Disease Adherence Questionnaire" for use in Brazil. METHOD A descriptive, transversal study with a quantitative approach. The cultural adaptation followed the steps of translation, professional committee, back translation, panel of patients and pretest. RESULTS the translation stage created a version in Port...

The aim of this study was to develop and validate an instrument for identifying nursing activities performed in a pediatric ward and to provide a basis for defining the workload of these units. The instrument was developed by selecting the activities relevant to pediatric nursing from the Nursing Intervention Classification and then submitting them to a panel of judges for validation. The panel...

T.W. Anderson and his collaborators have made seminal contributions to inference with instrumental variables and to dynamic panel data models. We review these contributions and the extensive economic and statistical literature that these contributions spawned. We describe our recent work in these two areas, presenting new approaches to (a) making valid inferences in the presence of weak instrum...

In this paper, we study the arrangement of displays in flight instrument panels of multi-purpose civil helicopters following a user-centered design method based on ergonomics principles. Our methodology can also be described as a user-interface arrangement methodology based on user opinions and preferences. This study can be outlined as gathering user-centered data using two different research ...

The Conversation Analysis Profile for People with Aphasia (CAPPA) provides specific information about strengths and weaknesses of the communication between people with aphasia and their family caregiver within a conversational context. Objective The aim of this paper was to present the results of the first stages of cross-cultural adaptation of the CAPPA for the European Portuguese language. ...

An immunoassay system based on enzyme immunoassay technology has been developed for quantitative panel testing. The system includes test card disposables, reagents, and an instrument. Patients' samples are processed semiautomatically in the instrument with minimum user intervention. The test card has multiple test areas at individual locations on a membrane solid phase so that simultaneous dete...

reduction in maternal mortality requires an in-depth knowledge of the causes of death. this study was conducted to explore the circumstances and events leading to maternal mortality through a holistic approach. using narrative text analysis, all documents related to maternal deaths occurred from 2007 to 2011 in kerman province/iran were reviewed thoroughly by an expert panel. a 93-item chart ab...
