BACKGROUND Rearing rats in environmental enrichment alters psychostimulant-induced locomotor activity as well as neurotransmitter expression. Exposure to novelty and psychostimulants induces c-fos expression in neurons in the mesolimbic dopamine (DA) pathway. Here we investigated changes in the expression of the immediate early gene c-fos in the mesolimbic DA pathway of enriched, isolated, or s...

Despite the large number of studies examining the impact of cage systems on Ca and P nutrition, data are limited on the N balance of hens when housed under different systems. To this end, an experiment was conducted to assess N balance, manure characteristics, and indices of the performance of laying hens housed in 2 distinct caging systems. A total of 4,836 commercial Shaver White hens were ho...

This review article revisits the role of static mixers in process industry nowadays and summarizes most relevant developments literature available on this type handling liquid-phase systems. In particular, seeks to discuss depth progress that has been made hydrodynamic understanding immiscible liquid–liquid dispersions emulsion formation using motionless types mixers, both through experimental ...

integration remains difficult. In contrast, we interpret the dramatic increases in the more simplifying, self-protective style of elders as a movement that is initiated with increasing vulnerability in regulating homeostatic processes, including emotions. Indeed, our research and that of others (see Labouvie-Vief, Grühn, & Mouras, in press; Labouvie-Vief & Marquez, 2004) suggests that high comp...

In this longitudinal study, we examined the moderating role of personality in the relationship between communication behaviors (withdrawal, dominance, criticism, support, and problem solving) and couple stability. At Time 1, 135 couples completed the NEO Five-Factor Inventory and the Dyadic Adjustment Scale. These couples were also videotaped during a 15-minute problem-solving discussion. Appro...

BACKGROUND In a previous study, we investigated the risk of admission to emergency (ER) of depressed patients prior to their hospitalization in psychiatry in comparison with hospitalized patients transferred from the consultations department (Cdpt). In the present study, we compare among the same patients variables affecting the intensity of depression in each group. METHOD All patients with ...

a relationship based on the modified couple stress theory is developed to investigate the flexural sensitivity of an atomic force microscope (afm) with assembled cantilever probe (acp). this acp comprises a horizontal cantilever, two vertical extensions and two tips located at the free ends of the extensions which form a caliper. an approximate solution to the flexural vibration problem is obta...

Retrieving semantic similar short texts is a crucial issue to many applications, e.g., web search, ads matching, question answer system, and so forth. Most of the traditional methods concentrate on how to improve the precision of the similarity measurement, while current real applications need to efficiently explore the top similar short texts semantically related to the query one. We address t...
