Resurgence has commonly been viewed as the recovery of an extinguished instrumental behavior that occurs when an alternative behavior that has replaced it is also extinguished. Three experiments with rat subjects examined the effects on resurgence of the temporal distribution of reinforcement for the alternative behavior that is presented while the first response is being eliminated. Experiment...

Fiber-reinforced asphalt concrete (FRAC) was tested using limestone, PG 64-22 binder, and 20% reclaimed pavement (RAP). After mixing fibers with different lengths dosages, they were extracted recovered to evaluate their dispersion in the FRAC. The uniaxial fatigue test, IDEAL CT flow number test performed on FRAC fiber contents. balanced mix design (BMD) approach then used analyze results order...

This paper deals with the strategies adopted by the Hindu Kush Himalayan (HK-H) mountain communities in response to adverse natural and human induced circumstances. The quality of life and growth options in mountains (including hills) are deeply rooted in mountain specificities (e.g., fragility, marginality, diversity). Hence, the disregard of these mountain specificities while using mountain r...

Human pendrin (SCL26A4, PDS) is a 780 amino acid integral membrane protein with transport function. It acts as an electroneutral, sodium-independent anion exchanger for a wide range of anions, such as iodide, chloride, formate, bicarbonate, hydroxide and thiocyanate. Pendrin expression was originally described in the thyroid gland, kidney and inner ear. Accordingly, pendrin mutations with reduc...

Behavioral momentum theory provides a quantitative account of how reinforcers experienced within a discriminative stimulus context govern the persistence of behavior that occurs in that context. The theory suggests that all reinforcers obtained in the presence of a discriminative stimulus increase resistance to change, regardless of whether those reinforcers are contingent on the target behavio...
