We consider a model of dynamic price competition to analyze the impact of consumer inertia on the ability of firms to sustain high prices. Three main consequences are identified: (i) maintaining high prices does not require punishment strategies when firms are sufficiently myopic, (ii) if buyers are sufficiently inert, then high prices can be sustained for all discount factors, and (iii) the ab...

We aimed to develop alternative fishing gear for catching the common octopus, to decrease the use of bait and operating costs in comparison to commercial net pots. A tubular-type pot was designed, and behavioral responses of the common octopus were experimentally monitored in tank and replicated 10 times to compare fishing performances between 300 experimental and 300 commercial net pots in the...

The effect of ball-milling on physicochemical properties of maize starch was evaluated. Results found that the cold water solubility (CWS) of maize starch was positively correlated with the time of milling up to 3 h. There was no significant influence of using a ceramic pot versus a stainless steel pot on CWS. However, following 5 h of ball-milling CWS increased quite dramatically in the cerami...

The goal of this study is to prospectively assess the additional value of oblique reformatted images for localizing POT, having surgery as a reference standard. Materials and Methods. 102 consecutive patients with suspected small bowel obstruction (SBO) underwent 64-slice multidetector row CT (MDCT) using surgical findings as reference standard. Two independent GI radiologists reviewed the CT s...

BACKGROUND The process of industrial xylitol production is a massive source of organic pollutants, such as waste xylose mother liquor (WXML), a viscous reddish-brown liquid. Currently, WXML is difficult to reuse due to its miscellaneous low-cost sugars, high content of inhibitors and complex composition. WXML, as an organic pollutant of hemicellulosic hydrolysates, accumulates and has become an...

Worldwide, the number of professional and sports divers is increasing. Most of them breathe diving gases with a raised partial pressure of oxygen (PO2 ). However, if the PO2 is between 50 and 300 kPa (375-2250 mmHg) (hyperoxia), pathological pulmonary changes can develop, known as pulmonary oxygen toxicity (POT). Although in its acute phase, POT is reversible, it can ultimately lead to non-reve...

The physico-chemical characteristics as well as chemical composition of Arachis hypogaea shell (AHS) ash were evaluated by different techniques such as X-Ray fluorescence, X-Ray diffraction and thermo-gravimetry. The material, which is considered a by-product obtained from Groundnut shelling, was investigated as a potential fertilizer, energy source and as animal feeds. And this will provide a ...

Among the conducting polymers, Polyaniline and its derivatives have been studied extensively in the last decade with improvements in processing having the key role in establishing the intrinsic electrical properties. In the present paper, the camphor sulphonic acid [CSA] doped Poly (o-toluidine) [POT] was prepared using chemical oxidative polymerization method. The prepared CSA doped POT was ch...

Original scientific paper Pear brandy is one of the most desirable alcoholic beverages across Europe. But of all varieties, the most appreciated is Bartlett pear or Williams’s pear as it is better known. The purpose of this work was to create an objective evaluation of the influence of various construction forms of pot still, (alembic, pot and spheric) on final quality of Williams pear brandy. ...
