We have reported that the postextrasystolic (PES) potentiation of left ventricular (LV) contractility usually decays in alternans at heart rates above 80-100 beats/min in the canine excised, cross-circulated heart. We examined whether the PES contractility would also decay in alternans even in the canine in situ heart presumably more physiological than the excised heart. In anesthetized, ventil...

Problems of simulation and control in production and economic system (PES) under condition of economy’s modernization are discussed in the paper. The developed control system considers the coordination of three systems – PES, market and taxation institutional system. We take into account the PES features as dynamism, large number of parameters, nonlinearity, nonstationarity, strong interconnect...

Polyethersulfone (PES) is one of the most important polymeric materials and is widely used in separation fields. PES and PES-based membranes show outstanding oxidative, thermal and hydrolytic stability as well as good mechanical and film-forming properties. PES membranes could endure many kinds of sterilized methods, including epoxy ethane gas, steam, and γ-ray. Furthermore, PES-based membranes...

There exist two distinct isozymes of prostaglandin-endoperoxide synthase (PES). PES-2 mRNA is synergistically induced by lipopolysaccharide (LPS) and 12-O-tetradecanoylphorbol-13-acetate (TPA) in bovine arterial endothelial cells. On the other hand, PES-1 mRNA is constitutively expressed under these conditions. Therefore, the promoter activities of the human genes for PES-1 and -2 in bovine art...

This paper presents a gradient-based parameter optimization method to find the optimal compensator that minimizes the standard deviation ( PES) of the position error signal (PES) in a hard disk drive servo system. By using the plant response data and the PES gradient information based on the nominal plant model, optimal digital controllers that minimized the 3 PES of a plant with uncertainty we...

Out-of-school peer educators [PE] are resourceful in transmitting reproductive health information but their retention remains a contentious issue. This study aimed to assess motivation and sustainability of out-of-school PEs in disseminating reproductive health information among adolescents. A structured questionnaire was used to interview 406 PEs in Mbeya region, Tanzania. Focus Group Discussi...

Background There is evidence for a group of nonclinical individuals with full-blown, persistent psychotic experiences (PEs) but no need-for-care: they are of particular importance in identifying risk and protective factors for clinical psychosis. The aim of this study was to investigate whether reasoning biases are related to PEs or need-for-care. Method Two groups with persistent PEs (clinic...

In sports, there is a constant discussion about the hyper-pronation and supination of the foot during loading and its relation to injuries or discomfort. The purpose of the present study was to investigate the possible differences in the subtalar joint in the midstance phase of running, between individuals with Pes Planus and Pes Cavus, after 5 min and 45 min of running. Thirty-four subjects, m...

Background Physiologic (flexible) pes planus (flatfoot) is a descriptive term for feet that have a visually lowered medial longitudinal arch often in association with rearfoot eversion [1]. Reported to affect approximately 15% of the adult population [2] physiologic pes planus can be categorised as either symptomatic (painful, non-functional) or nonsymptomatic (non-painful, functional) with the...

It is common, particularly in young people, to report psychotic experiences (PEs) such as feeling paranoid and having hallucinations. The questions of the role of genes and environment on PEs in the general population, and how PEs relate to schizophrenia, have not, until recently, been addressed empirically. New approaches demonstrate the heritability and role of the environment on the full ran...
