<p>Rad prezentira istraživanje u oblasti razumijevanja i pravilne upotrebe gramatičkih kolokacija među studentima engleskog jezika i književnosti na Univerzitetu u Zenici čiji je nivo stečenih jezičkih kompetencija B1, B2 i C1 prema zajedničkom referentnom okviru za jezike (CEFR). Uočeno je da čak i na naprednim nivoima učenja engleskog jezika postoje pote&scaron;koće u razumijevanju i pravilnoj upotrebi gramatičkih kolokacija kao i sklonost studenata da kolokativne kombinacije leksičkih i gramatičkih izraza i konstrukcija doslovno prenose na engleski jezik. Ispitanici su bili studenti engleskog jezika i književnosti Filozofskog fakulteta Univerziteta u Zenici. Korpus na kojem je rađeno istraživanje obuhvatao je prevode studenata od prve do četvrte, tj. zavr&scaron;ne godine studija engleskog jezika. Tekstovi koji su bili predmet analize su prevodi sa engleskog na BHS jezik i obrnuto, sa BHS jezika na engleski. Korpus na kojem je provedeno istraživanje su bilistudentski prevodi koji su predstavljali jedan dio zavr&scaron;nog ispita na predmetu Savremeni engleski jezik 1-8, a rađeni su u periodu od 7 godina, tj. 2008-2015. Preliminarno istraživanje upotrebe gramatičkih kolokacija kod studenata engleskog jezika nivoa B2 koje su proveli autori ovog rada pokazalo je da studenti gramatičke kolokacije pravilno upotrebljavaju tek u 50% slučajeva. Istraživanje se temeljilo na pretpostavci da se rezultati ispitivanja radova studenata na sve četiri godine studija neće bitno razlikovati od rezultata dobijenih u preliminarnom istraživanju.</p>

Synthetic materials in contact with protein containing solution adsorb a considerable amount of proteins. The adsorption behaviour of zinc-free porcine insulin on the hydrophobic poly(vinylidene fluoride) (PVDF) surfaces before and after chemical vapour deposition (CVD) modification was directly analysed by matrix-assisted laser desorption ionisation-time-of-flight-mass spectroscopy in surface mode (surfaceMALDI-TOF-MS). The MALDI mass spectra of Zn-free porcine insulin dissolved in carbonate buffer pH 8.3 after adsorption onto non-modified and modified PVDF-CVD surfaces contain peaks assigned to monomer ion peak as well as peaks that are results of degradation of Zn-free porcine insulin. The degradation is caused by structural changes taking place during adsorption of insulin onto hydrophobic surfaces and by subsequent laser induced desorption and ionisation process. Surface spectra of Zn-free porcine insulin dissolved in deionised water show only monomer ion peaks of porcine insulin without degradation product detected. Structure stability of Zn-free porcine insulin upon adsorption is influenced by hydrophobic interaction between insulin and the surface.

<p style="text-align: justify;">Measurements, calibrations of contact thermometer have been conducted on prototype/standard &ndash; apparatus for calibration of contact thermometers on solid surface (in following text just prototype). In order to make the calibration obtained result whole an estimation of measurement uncertainty is done. The possibility to vary parameter of influence of ambient temperature just above the reference surface is used. This parameter is directly derived from the construction of the prototype.</p>

<p style="text-align: justify;">The paper aims to answer if the industrial robot is a motif of accelerated trend of automation and modernisation of production processes in automotive industry in the world. It describes the application of industrial robots in the World for the period from 2009 &ndash; 2014. It offers analysis of the application of industrial robots in the automotive industry, as well as metal industry, which is also related to the automotive industry. Based on this analysis, conclusions were made about the role of industrial robots in the growing trend of modernisation and automation of production processes in the automotive industry. The role of industrial robots is interesting when it comes to energy efficiency, as well as the role of new materials from the aspect of weight reduction, as well as innovation when it comes to IT technology. Information technologies provide new softwares whereby we get a far greater utilization of industrial robots from the point of performing a large number of operations, and therefore improves the automation of production processes in the automotive industry. The materials and their combinations are always demanding both in the metal as well as in automotive industries, and require new skills with applications such as sewing, weaving and knitting all types of fiber (for the car industry) that represent a challenge and are introduced in robotics. Changes, such as integration of engineering disciplines, bring improvement in production processes. The paper gives an overview of the increase in the production of vehicles in the world through the use of industrial robots. The stated example is China, which is the first in the world by the application of industrial robots, and the first in the world for producing automobiles. Industrial robots are essentially a reason for the accelerated trend of modernization and automation of production processes in the automotive industry.</p>

<p style="text-align: justify;">Final product of the cold forming process gain many advantages that are mostly produced by strengthening of the material in the process. Those advantages are primarily explained as improving mechanical characteristic of the work material. Because of the effects of strengthening and as one of the specific methods of forming rotationally symmetrical parts in demanding industries increasingly applied forward cold flow forming (FCFF). In this paper is shown an example of forward cold flow forming application process in production of 99,5% Al workpieces with focus on analysis of a strengthening effect of the processed material by the change in its hardness like HB.</p>

<p style="text-align: justify;">The general solution of the plane problem in plastic region was given in the paper. This solution is limited to polar coordinates and the nonhardening material. In the paper are given same individual solutions of problems in the plastics region on the basis of the general solution. In this paper, on the basis of results of two papers earlier mentioned, the principal normal stresses are calculated in the ideal conditions and polar coordinates, which are the effect of a bending a sheet metal in the process of the deep drawing of rotation caps with a bottom. In this way, the directly calculation of the additional stress because of the bending and the correction of a sheet across a radius of a die for drawing is enabled in<br />mentioned process, which increased stresses in a wall of the cap and a force of drawing.</p>

This paper deals with cartographic depictions of religious facilities and cemeteries in Bosnia and Herzegovina on cadastral maps created during the Austro-Hungarian administration. It shows how cartographic depictions of these plans changed over time, based on collections of topographic symbols published in the late 19th and the early 20th century. Relevant cartographic sources depicting religious buildings were identified and collected through analysis of genuine archival documents, i.e. relevant cartographical sources of different scales and types. The research of the materials resulted in a scientific description of the most important aspects of religious facilities belonging to different religious communities in Bosnia and Herzegovina.

Direct potentiometric method for determination of penicillamine in pharmaceuticals by using commercial copper ISE is described. Proposed method is very inexpensive, simple and reasonably fast method for determination of Pen in acetic buffer, pH = 4 without pretreatment of pharmaceuticals. Determination is based on the reaction between Pen and Cu 2+ from electrode membrane. Described method has linear response range for Pen from 2×10 −6 to 1×10 −2 mol L −1 with limit of detection of 1.1×10 −6 mol L −1 . Found concentrations of Pen are in very good agreement with declared ones with standard deviation values in range 4.00−4.50 %.

Research in this paper is oriented towards structural changes at the division level of the manufacturing industry. The goal of the research is to point at the significance of the efficient structural reforms of Serbia’s manufacturing industry, more precisely to point at the size, intensity, speed and directions of the changes made in its structure. In the paper, the basic indicators of structural changes are used, namely the trend of the share of employment and the value added. The size of the changes is analyzed by the standard deviation and the dispersion of growth rates, whereas the intensity of changes is analyzed by the elasticity of the divisions’ growth rates. A correlation analysis is used to determine the directions and nature of the connectedness of structural changes between divisions, whereas the direction of changes is shown by the Spearman rank correlation coefficient of their growth rates. The Structural Change Indicator is used for researching the pace and patterns of structural changes. At the division level, by applying the comparison method, differences in the directions, speed and patterns of the structural changes of the Serbian manufacturing industry are analyzed against the new EU member states for which there are comparative data (Bulgaria, Romania, Hungary, the Czech Republic, Poland, Slovenia and Slovakia). The research results indicate that growth rates were higher in those divisions in which reforms were more comprehensive, faster, more intensive and efficiently fully implemented.
