Boron-contained molecular capsules triggered by amines are described for the first time; when Et3N was employed as a chemical stimulus the Lewis acid Et3NH+, produced by solvolysis reaction on the boron, was found to be encapsulated in the internal cavity, whereas use of nBu3N led to the related dynamic capsule capable of accommodating several guest species including Cs+.

Response-time and accuracy costs as assessed in the context of the task-switching paradigm are usually thought to represent processes involved in the selection of abstract task sets. However, task sets are also applied to specific stimulus and response constellations, which in turn may become associated with task-set representations. To explore the consequence of such associations, we used a ta...

Introduction: The main objective of the present study was to investigate the effect of preceding pictorial stimulus on the emotional autonomic responses of the subsequent one. Methods: To this effect, physiological signals, including Electrocardiogram (ECG), Pulse Rate (PR), and Galvanic Skin Response (GSR) were collected. As these signals have random and chaotic nature, nonlinear dynamics...

results survival at 1-year, 2-years, 3-years and 5-years was 73.2%, 45.4%, 33.2% and 14.9% respectively. procedure-related mortality was 1.4%. multivariate analysis showed lesion diameter, child-pugh classification, alcohol abuse, tumor response and afp prior tace as independent prognostic factors of survival. patients diagnosed during surveillance had significantly better survival rates compar...

The present investigation aimed to conduct a genetic study of dairy cattle and buffalo bulls based on economic traits and their phenotypic correlation. The means of various economic traits in both the species are presented. Cattle bulls reported a better libido score, Flehmen response, requirement of mounting stimulus and semen volume, conception rate and expected predicted difference for milk ...

Objective and Background The aim of this study was so assess the knowledge and attitude of the people in Iran regarding the antibacterial resistance caused by antibiotics. Introduction increasing concern toward antibiotic resistance led to many researches on the causes of this issue. The public awareness plays a critical role, according to the studies. Another important factor...

To engage with questions of musicality is to invite into consideration a complex network of topics beyond the mechanics of soundful interaction with our interfaces. Drawing on the work of Born, I sketch an outline of the reach of these topics. I suggest that practice-led methods, by dint of focussing on the lived experience where many of these topics converge, may be able to serve as a useful m...

today physical researchers and teachers consider exercise as a key element to improve motor skills; it is also evident that changeability in practice for retention and performance skills is both proper and effective. the main idea of this study was to evaluate the effectiveness of random and blocked practice methods on retention and performance ability of 12-year-old learners’ passing skills in...
