Bibliometric analysis in the evaluation of journals published by the Forest Research Institute: Forest Research Papers and Folia Forestalia Polonica Series A – Forestry

In recent years, there has been a significant increase in interest in publishing articles in journals recorded by global databases, in particular the Web of Science ™ Core Collection, which indexes journals found in the Journal Citation Reports. The publication of results in these journals has a significant impact on the assessment of the achievements of researchers and scientific institutions. Our study focused on the bibliometric analysis of two journals published by the Forest Research Institute: Forest Research Papers (Leśne Prace Badawcze) and Folia Forestalia Polonica Series A – Forestry. The results of these analyses were used to develop theoretical indices for the editorial boards of these journals in terms of requirements for including both periodicals in the Journal Citation Reports. The analysis covered the volumes published in 2000–2015 and the publication activity of the journals was evaluated on the basis of the numbers of articles, references, authors and journal citations. Bibliometric indicators such as the predicted Impact Factor, the Hirsch index, the Scimago Journal Rank and the Index Copernicus Value were used to evaluate the rank of the journals within the databases. In the examined period, 65 volumes of Forest Research Papers were published, with an average of 31 articles per year containing about 14,000 references and almost 900 contributing authors. During the same time frame, 30 volumes of Folia Forestalia Polonica Series A – Forestry were published, with an average of 14 articles per year. These articles included approximately 5,000 references and 600 authors. An increase in the bibliometric indicators for both journals was observed with the Impact Factor predicted to rise to 0.192 (Forest Research Papers) and 0.178 (Folia Forestalia Polonica Series A – Forestry). In order for the two examined journals to be included in the Journal Citation Reports the following requirements need to be met: (1) an increased number of articles published by authors with significant international authority in their field, (2) a greater number of researchers, especially from developed countries, in advisory boards, (3) more articles published in individual volumes to reach higher citation numbers in databases, and (4) promotion of the most cited articles

IUPAC-NIST solubility data series. 81. Hydrocarbons with water and seawater-revised and updated. Part 5. C7 hydrocarbons with water and heavy water

The mutual solubility and related liquid-liquid equilibria of C7 hydrocarbons with water and heavy water are exhaustively and critically reviewed. Reports of experimental determination of solubility in 23 chemically distinct binary systems that appeared in the primary literature prior to end of 2002 are compiled. For 9 systems sufficient data are available to allow critical evaluation. All data are expressed as mass percent and mole fraction as well as the originally reported units. In addition to the standard evaluation criteria used throughout the Solubility Data Series, a new method based on the evaluation of the all experimental data for a given homologous series of aliphatic and aromatic hydrocarbons was used

Production Summary for Extended Barrel Module Fabrication at Argonne for the Atlas Tile Calorimeter.

The Tile Calorimeter is one of the main hadronic calorimeters to be used in the ATLAS experiment at CERN [1,2]. It is a steel/scintillator sampling calorimeter which is built by stacking 64 segments in azimuth and 3 separate cylinders to provide a total structure whose length is approximately 12m and whose diameter is a little over 8.4m. It has a total weight of about 2630 metric tons. Important features of this calorimeter are: A minimum gap (1.5mm) between modules in azimuth; Pockets in the structure to hold the scintillator tiles; Recessed channels at the edges of the module into which the readout fibers will sit; and Holes in the structure through which a radioactive source will pass. The mechanical structure for one of the 3 calorimeter sections, the Extended Barrel (EBA) was constructed at Argonne. A schematic of the calorimeter sampling structure and the layout of one of the 64 segments, termed a module, are shown in figure 1. Each module comprises mechanically of a precision machined, structural girder to which 10 submodules are bolted. One of these submodules, the ITC, has a customized shape to accommodate services for other detector elements. Each submodule weighs 850Kg and the assembled mechanical structure of the module weighs approximately 9000Kg (a fully instrumented Extended Barrel modules weighs {approx}9600Kg). A crucial issue for the tile calorimeter assembly is the minimization of the un-instrumented gap between modules when they are stacked on top of each other during final assembly. The design goal was originally 1mm gap which was eventually relaxed to 1.5mm following a careful evaluation of all tolerances in the construction and assembly process as shown in figure 2 [3]. Submodules for this assembly were produced at 4 locations [4] using tooling and procedures which were largely identical [5]. An important issue was the height of each submodule on the stacking fixture on which they were fabricated as this defines the length along the girder for installation, with a design gap between submodules on the girder of 0.3mm. During production we relaxed this tolerance to +0.3, -1.5mm. The height summary for submodules used at Argonne is shown in Appendix I. About 10 submodules fell outside the positive height envelope (due to the raw plate thickness being out of specification) and we constructed some custom short submodules to allow their use in module assembly. The structural girders were produced commercially following the Quality Control plan agreed to with the Tile Calorimeter collaboration and shipped to Argonne. The crucial tolerances on the girder are the key into which submodules are placed as well as the flatness of the key surface which are used in aligning submodules such that the azimuthal surface lies wholly an envelope of +0.75mm from nominal [6]. Another important characteristic of the girder are clearance holes through which the wavelength shift fibers pass to couple the light to photomultipliers located inside the girder, as described in [2]. Since these fiber bundles must be located to high precision, rather than position the holes in the steel to this precision, tooling was developed by which the precision pieces are glued into the girder [7]. This is shown in figure 3. More details on the pieces used to accomplish this interface to the readout electronics are discussed in [2]

Thermodynamics of mixtures with strongly negative deviations from Raoult's law. XV. Permittivities and refractive indices for 1-alkanol + n-hexylamine systems at (293.15–303.15) K. Application of the Kirkwood-Fröhlich model

Relative permittivities at 1 MHz, , and refractive indices at the sodium D-line, , are reported at 0.1 MPa and at (293.15–303.15) K for the binary systems 1-alkanol + n-hexylamine (HxA). Also, their corresponding excess functions are calculated and correlated. Positive values of the excess permittivities, , are encountered for the methanol system, whereas the remaining mixtures show negative values. This reveals that interactions between unlike molecules contribute positively to . This contribution is dominant for the methanol mixture, while those arising from the breaking of interactions between like molecules are prevalent for the remaining mixtures. At (volume fraction) = 0.5, changes in the order: methanol > 1-propanol > 1-butanol > 1-pentanol < 1-heptanol. Similar variation with the chain length of the 1-alkanol is observed for mixtures such as 1-alkanol + heptane, or + cyclohexylamine, and can be explained in terms of the lower and weaker self-association of longer 1-alkanols. The effect of the replacement of HxA by cyclohexylamine, or by aniline, is also shown. Calculations on molar refractions indicate that dispersive interactions in the systems under study increase with the length of the 1-alkanol. The mixtures are studied by means of the application of the Kirkwood-Fröhlich model, and the Kirkwood correlation factors, including the corresponding excess values, are reported.Ministerio de Educación, Cultura y Deporte for the grants FPU14/04104 and FPU15/05456 respectively.

Mechanical construction and installation of the ATLAS tile calorimeter

This paper summarises the mechanical construction and installation of the Tile Calorimeter for the ATLAS experiment at the Large Hadron Collider in CERN, Switzerland. The Tile Calorimeter is a sampling calorimeter using scintillator as the sensitive detector and steel as the absorber and covers the central region of the ATLAS experiment up to pseudorapidities +/- 1.7. The mechanical construction of the Tile Calorimeter occurred over a period of about 10 years beginning in 1995 with the completion of the Technical Design Report and ending in 2006 with the installation of the final module in the ATLAS cavern. During this period approximately 2600 metric tons of steel were transformed into a laminated structure to form the absorber of the sampling calorimeter. Following instrumentation and testing, which is described elsewhere, the modules were installed in the ATLAS cavern with a remarkable accuracy for a structure of this size and weight
