The effects of confining a polyelectrolyte solution containing a polyion and its counterions in spherical cavities of different sizes have been investigated by Monte Carlo simulations using a simple model system. Polyions of three different linear charge densities and counterions of three different valences have been examined. Structure, energy, and free energy properties of all systems have been

BACKGROUND: Induced hypothermia may be used to reduce metabolism in acute respiratory failure. Hypothermia is accompanied by an increase in pulmonary vascular resistance, as also seen in the early period after lung transplantation. It was our concern that the combination of the two would lead to an increased workload on the right ventricle. METHODS: To test this hypothesis we induced hypothermia t

The mutational mechanism underlying the striking diversity in MHC (major histocompatibility complex) genes in vertebrates is still controversial. In order to evaluate the role of inter- and intragenic recombination in MHC gene diversification, we examined patterns of nucleotide polymorphism across an exon/intron boundary in a sample of 31 MHC class IIB sequences of three-spined stickleback (Gaster

Security in organizations is no longer just a matter of having locks and alarms; it is more like a question of different dimensions of rules, perceptions and actions. The focus must return to more interpersonal relationships in security issues instead of technically advanced equipment. In facing today’s challenges, the focus must be on more interpersonal relationships in security issues than on te

Over the past decades, the field of in vivo magnetic resonance (MR) has built up an impressive repertoire of data acquisition and analysis technologies for anatomical, functional, physiological, and molecular imaging, the description of which requires many book volumes. As such it is impossible for a few authors to have an authoritative overview of the field and for a brief article to be inclusive

The setting (distance between mantle and concave ring) of the Hydrocone cone crusher is altered, even with the crusher operating at full load, by lifting or lowering the mantle by means of a hydraulic piston (Hydroset). Modern developments in the field of electronics and microcomputers have made it possible to design a small, reliable and very sophisticated system for automatic regulation of the s

OBJECTIVES: To study 40-55 mm aneurysms and calculate their size in relation to the individual predicted normal aortic diameter to see if this might add anything in the evaluation of treatment. MATERIAL AND METHODS: The anteroposterior diameter of 40-55 mm AAAs was measured with an echo-tracking ultrasonic technique in 147 consecutive patients. The weight and height were registered and body surfac

Global error bounds are derived for full Galerkin/Runge-Kutta discretizations of nonlinear parabolic problems, including the evolution governed by the p-Laplacian with p >= 2. The analysis presented here is not based on linearization procedures, but on the fully nonlinear framework of logarithmic Lipschitz constants and an extended B-convergence theory. The global error is bounded in L-2 by Delta

The aim of this retrospective study was to analyze survival and prognostic factors in 111 consecutive patients undergoing curative resection of liver metastases from colorectal cancer. In addition, the time periods 1971-1984 and 1985-1995 were compared; criteria for first liver resection did not change with time, whereas the attitude toward re-resection was more aggressive during the latter period

This study examines the effect of dual role advisors in acquisitions on shareholder value creation for both the acquirer and target. Dual role advisors are advisors that provide both advisory services to either the acquirer or target and are involved in underwriting or syndicating securities issued to finance the deal. Previous studies find that being a dual role advisor can create a conflict of i

The conflict in Ukraine is not only a conflict in a strictly traditional or material sense, in terms of a quest for territory or over military power. Rather, it is a conflict where the battlefield is located in the United Nations Security Council, and the battle is a verbal war between ambassadors and diplomats about conflicting narratives and how the conflict should be defined. In this thesis, a

The energy resources (notably oil and gas) are of strategic significance for national power. The resources are significant in both economic terms constituting the drivers of global economy and in political terms. The political essentials of the resources make their “high card” status in the international political gamble. The “high card” status stems from the assessment that the holder of the “car
