Abstract During the uploading of data for submission to the EudraCT results database, a discrepancy was identified. It was noted that the number of deaths per group was not consistent with the number in the final report and trial publication. This discrepancy was found to relate to two randomisation numbers. During the trial, the randomisation database had been held separately from the trial database, with manual transcription of randomisation numbers from the randomisation database to the trial database. Two randomisation numbers had been entered incorrectly into the trial database and, altho

This paper proposes a method for solving the problem on determining the unknown composition of a gaseous hydrocarbon fuel during its combustion in real time. The problem had been defined as the inverse, ill-posed problem. A technique for measuring technological parameters makes it possible to specify it as a complex interpretation problem. To solve it, a "library" method has been selected (selection), which is the most universal one. To implement it, a method has been constructed to compile a library in the form of a working three-dimensional array. The source data for each solution

Abstract:

The topic of expansion of numbers (or mathematical expansions)involves representing numbers in various forms and studying their interrelationships. This field is especially relevant in mathematical analysis and algebra. The study of number expansions primarily focuses on their fractional, rational, or decimal representations and exploring their logical and analytical properties. Key concepts in number expansions include decimal expansions, fractional expansions, and periodic expansions. Decimal expansions are particularly important for calculating precise values in the real number system.Fract

Abstract:

Understanding decimal numbers is very important to have. Many things in everyday life involve the concept of decimal numbers. Limitations in interpreting decimal numbers can result in errors, such as inaccuracies in measurement activities. In addition, it can also cause obstacles in learning other mathematical material, such as geometry and statistics. Given the importance of understanding decimal numbers, elementary school students need to interpret them properly. This study aims to analyze student learning obstacles related to decimal number material. Through this research, it is hoped that

Därför har jag fokuserat mitt arbete på övergången från heltal till decimaltal. Syftet med undersökningen är att belysa vikten av att lärare har goda matematiska och metodiska kunskaper, hur elever utvecklar sin taluppfattning och förhoppningsvis ge lite tips och idéer som kan användas i undervisningen med elever.

Abstract:

AbstractEquivalence checking of two programs is often reduced to the safety verification of a so-called product program that aligns the programs in lockstep. However, this strategy is not applicable when programs have arbitrary loop structures, e.g., the numbers of loops vary. We introduce an automatic iterative abstraction-refinement-based technique for checking equivalence of a single-loop program and a program which has a series of consecutive loops. Our approach decomposes the single loop into a sequence of separate loops thus reducing the main problem to a series of equivalence-checking problems for pairs of loops. Since due to the decomposition, these problems become abstract, our approach iteratively refines the decomposed loops and lifts useful information across them. Our second contribution is a procedure for the alignment of loops with counters and explicit bounds that cannot be composed in lockstep. We have implemented the approach and successfully evaluated it on two suites, one with benchmarks containing different numbers of loops and the other containing benchmarks that need alignment.

Abstract A caliper survey of the horizontal well MFF-25A in the Dan field showed that the tubing was severely corroded with several fully penetrating holes. This study investigated whether the accelerated corrosion was caused by microorganisms. The number and nature of microorganisms in samples of downhole deposits was determined using quantitative polymerase chain reaction (qPCR). Furthermore, wavelength dispersive X-Ray fluorescence spectroscopy (WDXRF) was conducted for elemental composition analysis of corrosion products. Produced water samples were also collected and analyzed with qPCR. T

Abstract:

Abstract Several nickel alloys containing high chromium contents, and other elements known to enhance resistance to metal dusting, were tested in a flowing gas mixture of 68% CO + 26% H2 + 6% H2O at 680°C, corresponding to aC = 2.9. The onset of dusting was accelerated by using temperature cycling conditions, to shorten the life of otherwise protective oxide scales. The total duration of the test was 1,200 cycles, each of 45 min at temperature, and 15 min cooling. All test alloys developed chromia scales, but dusted to some extent, developing filamentary carbon deposits decorated with metal na

Abstract:

Abstract Corrosion inhibition using different inhibition methods have been used in North America. One method that is popular in North America is batch treatment. Batch treatment is attractive to use in North America as there are large numbers of wells and it is expensive to place pumps and capillary injection facilities with large number of wells. In this paper the performance of film persistent corrosion inhibitors that are effective at fairly high temperatures and in systems that see large amounts of carbon dioxide (CO2) is described. Wells that have large amounts of CO2 are extremely corros

Abstract:

Abstract Erosion-corrosion is flow-assisted corrosion that can cause wall thinning in fluid piping systems. Several key parameters, such as pH, temperature, flow rate, mass transfer coefficient (which is a function of the geometry and pipe configuration), and materials determine the rate at which damage develops. In this study, we generated an experimental data base from the open literature which we used to train and to test an Artificial Neural Network (ANN). We also developed a deterministic model which we used to make predictions. The predictions from the deterministic model, and from the A

Abstract:

Asserting the phase stability of multi-component mixtures is an important task in computer-aided mixture/blend design (CAMbD), but it is often hindered by the lack of reliable and tractable models. In this paper, we propose a group-contribution machine-learning (GC-ML) method to predict phase coexistence for a large set of ternary mixtures consisting of two solvents and one (fixed) solute. Each solvent is represented by a vector of functional group numbers, encoded by integer values. The solvent vectors are combined with mixture composition and temperature to form the input features to a GC-ML

Abstract:

The creation of Hindu mathematicians had an enormous influence on the subsequent evolution of arithmetic (the Hindu positional decimal number system), algebra (dispersion method for solving indeterminate equations of the first and second degree with two unknowns) and trigonometry (infinite strings for sine, cosine and arctangent). The earliest information with reference in Ancient India relates to the era of the composition of the philosophical-religious holy books "The Vedas".

Abstract:

Hanne Darboven’s (1941-2009) Opus 17a is a composition for solo double bass that is rarely performed due to the physical and mental challenges involved in its performance. It is one of four opuses from the composers monumental 1008 page Wünschkonzert (1984), and was composed during her period of making “mathematical music” based on mathematical systems where numbers were assigned to certain notes and translated to musical scores. It can be described as large-scale minimalism and it is highly repetitive, but even though the same notes and intervals keep repeating, the patterns slightly change t
