Multi-domain recombinant proteins have a cutinase catalytic domain. The cutinase catalytic domain is a modular domain, which may be combined with other protein domains that also function in a modular fashion. For example, the cutinase catalytic domain can be operably linked to a polymer binding domain via a linker domain (e.g., a threonine/proline-rich linker polypeptide). The cutinase catalytic domain can be from an endogenous cutinase having a multi-domain modular organization, such as from the actinobacterium Kineococcus radiotolerans. The recombinant proteins are used in compositions, methods and uses, such as for use in industrial applications.

A material for storing hydrogen is prepared by a method including an extreme plastic deformation operation selected from cold-rolling, quick-forging and extrusion-bending performed on a metallic material selected from among a metal and an alloy containing said metal, or on a compound containing a metal material selected from among a metal and an alloy containing said metal and to which a hydride of said metal or a hydride of said alloy has been added. When the extreme plastic deformation operation is carried out on the metallic material, it is followed by an operation of adding, to the metal material, a hydride of said metal or a hydride of said alloy, as well as by a dispersing operation.

Quantum Bayesianism, or QBism, is a recent development of the epistemic view of quantum states, according to which the state vector represents knowledge about a quantum system, rather than the true state of the system. QBism explicitly adopts the subjective view of probability, wherein probability assignments express an agent’s personal degrees of belief about an event. QBists claim that most if not all conceptual problems of quantum mechanics vanish if we simply take a proper epistemic and probabilistic perspective. Although this judgement is largely subjective and logically consistent, I explain why I do not share it. © 2015, The Author(s).

The attentional blink (AB) refers to the difficulty in reporting a second target (T2) presented shortly after a first target (T1) in a stream of distractors. The goal of the present study was to investigate distractor-based interference in the AB by recording the P3 component of the event-related potential to both targets. An intertarget distractor was presented at lag 1 (T1+1), at lag 2 (T1+2), or at neither of these two lags (no distractor). T2 was always presented at lag 3, as the last item in the stream. In two experiments, the P3 from T1 was attenuated in the T1+1 condition compared to the two other distractor conditions. In absence of a task switch (Experiment 1), the P3 from T2 was delayed in both the T1+1 and T1+2 conditions. In the presence of a task switch (Experiment 2), the P3 from T2 was delayed only in the T1+1 condition. Results demonstrate that intertarget distractors can modulate the AB directly but only in absence of a task switch. © 2015 Society for Psychophysiological Research.

In this paper, an adaptive fuzzy control scheme is introduced for permanent magnet synchronous machines (PMSMs). The adaptive control strategy consists of a Lyapunov stability-based fuzzy speed controller that capitalizes on the machine's inverse model to achieve accurate tracking with unknown nonlinear system dynamics. As such, robustness to modeling and parametric uncertainties is achieved. Moreover, no explicit currents loop regulation is needed, which simplifies the control structure and unlike other control strategies, no a priori offline training, weights initialization, parameters knowledge, voltage, or current transducer is required. The system's convergence and stability are proved by Lyapunov stability theory, which yields an improved performance. Simulation results for different situations highlight the performance of the proposed controller in transient, steady-state, and standstill conditions. Furthermore, the adaptive fuzzy systems inherent parallelism makes them a good candidate for implementation in real-time PMSM drive systems. © 2011 IEEE.

We report the complexation of bovine serum albumin (BSA) with several dendrimers of different compositions mPEG-PAMAM (G3), mPEG-PAMAM (G4), and PAMAM (G4) at physiological conditions using constant protein concentration and various dendrimer contents. FTIR, CD, and fluorescence spectroscopic methods were used to analyze polymer binding mode, the binding constant, and the effects of dendrimer complexation on BSA stability and conformation. Structural analysis showed that dendrimers bind BSA via hydrophilic and hydrophobic interactions with a number of bound polymers (n): 1.30 for mPEG-PAMAM-G3, 1.30 for mPEG-PAMAM-G4, and 1.0 for PAMAM-G4. The polymer - BSA binding constants were KmPEG-G3 = 5.0 (±0.8) x 103 M-1, KmPEG-G4 = 1.0 (±0.3) x 104 M-1, and K PAMAM-G4 = 1.1 (±0.4) x 104 M-1. Dendrimer binding altered BSA conformation with a major reduction of α-helix and an increase in random coil and turn structures, indicating a partial protein unfolding. © 2010 American Chemical Society.

Objective: This article describes the results of a study analyzing several discourses on the values of occupational therapy and some philosophical assumptions upon which these values are based. Method: A qualitative study of several values statements using the hermeneutical method-a conventional analytical approach in philosophy-was conducted. Results: The literature review reveals that opinions on the values of occupational therapy differ greatly-no one value is shared among all the values statements examined. However, the majority of the texts mention occupational participation. A philosophical analysis of the literature shows that this value is based on a conception of human beings that can be traced back to the philosophical anthropologies of thinkers like Marx, Rousseau, Sartre, and Kant. The philosophical analysis also brought to light a certain conceptual confusion about what a value is. Conclusions: This article therefore offers some conceptual clarifications to help distinguish between values, beliefs, attitudes, principles, and non-evaluative concepts. It also presents the implications for practice of this philosophical analysis of values statements of the profession. © 2014 Informa Healthcare.

There are several lipid binding sites on serum albumins. The aim of this study was to examine the binding of bovine serum albumin (BSA) to cholesterol (Chol), 1, 2-dioleoyl-3-(trimethylammonium)propane (DOTAP), (dioctadecyldimethyl)ammonium bromide (DDAB), and dioleoylphosphatidylethanolamine (DOPE), at physiological conditions, using constant protein concentration and various lipid contents. Fourier transform infrared (FTIR), circular dichroism (CD) and fluorescence spectroscopic methods were used to analyze the lipid binding mode, the binding constant, and the effects of lipid complexation on BSA stability and conformation. Structural analysis showed that lipids bind BSA via both hydrophilic and hydrophobic contacts with overall binding constants of KChol = (1.12 ± 0.40) × 103 M-1, KDDAB = (1.50 ± 0.50) × 103 M-1, KDOTAP = (2.45 ± 0.80) × 103 M-1, and KDOPE = (1.35 ± 0.60) x 103 M-1. The numbers of bound lipid (n) were 1.1 (cholesterol), 1.28 (DDAB), 1.02 (DOPE), and 1.21 (DOTAP) in these lipid-BSA complexes. DDAB and DOTAP induced major alterations of BSA conformation, causing a partial protein unfolding, while cholesterol and DOPE stabilized protein secondary structure. © 2010 American Chemical Society.
