Choice behavior was studied under concurrent nonindependent fixed-ratio fixed-ratio (nFR) schedules of reinforcement, as these schedules result in frequent changeover responses. With these schedules, responses on either operandum count toward the completion of the ratio requirements of both schedules. Five monkeys were subjects, and two pairs of liquid reinforcers were concurrently available: 1...

OBJECTIVE To translate the Need for Recovery Scale (NFR) into Brazilian Portuguese and culturally adapt it and assess the stability, internal consistency and convergent validity of the Brazilian scale among industrial workers. METHODS The translation process followed the guidelines for cultural adaptation of questionnaires including the steps of translation, synthesis, back translation, exper...

Background : 1st and 2nd generation cephalosporins used for perioperative prophylaxis in orthopaedic surgery do not cover non-fermenting Gram-negative rods (NFR). Methods: Epidemiological cohort study of adult patients operated for orthopedic infections between 2004 and 2014 with perioperative cefuroxim or vancomycin prophylaxis. Exclusion of polyneuropathic ischemic foot infections and septic ...

The nociceptive flexion reflex (NFR) has been used as a psychophysiological tool to study spinal nociceptive processes in numerous clinical and experimental studies. Despite widespread use of the NFR, few attempts have been made to empirically test and compare different scoring criteria to detect the presence/absence of the reflex. The present studies were conducted to address this issue. Study...

Non-functional requirements (NFR) are fundamental for the software development. The NFRFramework allows the elicitation to deeply cover necessary trade-offs involving synergetic and conflicting solutions. It also favor the capture of design decisions involving the reasons that lead one to choose between one alternative and another to implement a NFR. This work proposes and describes the NDR-Too...

Software Development has started experiencing the need of consideration of NFR (Non Functional Requirements) for producing high quality acceptable software. Mostly software engineering literature has considered only for testing Functional Requirements. In context of such a need this work attempts to consider NFR, resulting from quality concerns of stakeholder, along with their impact and effect...

The short allele of the serotonin transporter gene (5-HTTLPR) is associated with greater negative emotionality. Given that emotion modulates pain, short allele carriers (s-carriers) may also demonstrate altered pain modulation. The present study used a well-validated emotional picture-viewing paradigm to modulate pain and the nociceptive flexion reflex (NFR, a measure of spinal nociception) in ...

Most of the research related to Non Functional Requirements (NFRs) have presented NFRs frameworks by integrating non functional requirements with functional requirements while we proposed that measurement of NFRs is possible e.g. cost and performance and NFR like usability can be scaled. Our novel hybrid approach integrates three things rather than two i.e. Functional Requirements (FRs), Measur...

near-far-ratio (NFR = EJE,, i = 2,3,4,5) with the signal-to-noiseratio (SNR) of user 1 being futed at 8dB. It can be seen from Fig. 1 that the TSTCNN detector outperforms the HNN detector over the NFR range. When the NFR is low, the TCNN detector has poor performance. As the NFR increases, the performance of both the TCNN detector and the TSTCNN detector approach that of the optimum detector cl...

Domain analysis in software product line (SPL) development provides a basis for core assets design and implementation by a systematic and comprehensive commonality/variability analysis. In feature-oriented SPL methods, products of domain analysis are domain feature model and corresponding feature decision model to facilitate application-oriented customization. As in requirement analysis for a s...
