Bogolitsyn K., gusakova m., samsonova n., selivanova n., Pochtovalova a.: Integral indices for quality assessment of pulp and paper mill effluents. Ekológia (Bratislava), vol. 33, no. 1, p. 60–66, 2014. The first part of this investigation studied complex nature of chemical oxygen demand (cod) parameter on local and overall effluents, which were obtained from two pulp and paper mills, located i...

Few direct-assessment procedures are designed to identify potential negative reinforcers (e.g., including demands in the escape condition of functional analyses). Two participants were systematically exposed to a series of demands nominated by caregivers as potential negative reinforcers. Sessions ended following the first instance of problem behavior, and a hierarchy of demand aversiveness was...

This paper studies collusion in repeated Bertrand oligopoly when stochastic demand levels for the product of each rm are their private information and are positively correlated. It derives general su cient conditions for e cient collusion through communication and a simple grim-trigger strategy. This analysis is then applied to a model where the demand signal has multiple random components whic...

It is very hard, if not impossible, to obtain by using dynamic programming the optimal policy for a stochastic linear production-inventory system. Therefore simplifications are necessary. Mostly in practical situations a certainty-eauivalence policy is adopted. Another approach is that developed by Holt, Modigliani, Muth and Simon (HMMS) 14 1. They approximate the cost functions by quadratics a...

Toe walking is a gait deviation with multiple etiologies and often associated with premature and prolonged ankle plantar flexor electromyographic activity. The goal of this study was to use a detailed musculoskeletal model and forward dynamical simulations that emulate able-bodied toe and heel-toe walking to understand why, despite an increase in muscle activity in the ankle plantar flexors dur...

This paper reports the design of a tactile sensor patch to cover large areas of robots and machines that interact with human beings. Many devices have been proposed to meet such a demand. These realizations are mostly custom-built or developed in the lab. The sensor of this paper is implemented with commercial force sensors. This has the benefit of a more foreseeable response of the sensor if i...

In rabbit papillary muscle contracting at 20 degrees C in nitrogen at 0.2 Hz, glycolytic ATP formation is just enough to support the diminished contractile activity. Basal metabolism, important to maintain cellular function and integrity, is strongly inhibited. In the present study, we address the question of whether the inhibition of basal processes in hypoxia determines redevelopment of force...

Intra-arterial therapy is currently applicable to a small subset of patients with ischemic stroke, but it will likely have an expanding role as new devices are introduced. This review evaluates the demand for such therapy and the physician work force available to provide such therapy in the United States. The available literature was reviewed to assess how many patients might need intra-arteria...

   High strength and elastic biodegradable membranes are of great demand in modern technology. Similar membranes have been developed by irradiating different weight poly (vinyl alcohol) (PVA) – hydroxypropyl guar gum (HPG) blends and followed by combining with ex situ nanosilica. Polarized light microscopic (PLM) study indicates that electron beam irradiation produced crosslinks and develop...

The aim of this work was to investigate effect of operational parameters on the photocatalytic degradation efficiency of a solution containing C. I. Basic Blue 41 BB41 in a recirculated rectangular photoreactor irradiated with a UV light. TiO_2 nano composite film was prepared via sol-gel dip coating method. The films were characterized by X-ray diffraction XRD, transmission electron microscopy...
