Exocytosis is a general concept describing secretion of enzymes, hormones and transmitters that are otherwise sequestered in intracellular granules. Chemical evidence for this concept was first gathered from studies on chromaffin cells in perfused adrenal glands, in which it was found that granule contents, including both large protein and small molecules such as adrenaline and ATP, were released together while the granule membrane was retained in the cell. A number of exhaustive reviews of this early work have been published and are summarized in Reference 1. The critical experiments demonstrating the importance of extracellular calcium for exocytosis per se were also first performed in this system (2,3), further indicating the substantial service given by chromaffin cells to those interested in secretory phenomena over the years.

The work aims to show a peculiar perspective of looking at photographs taken on the eve of the broadly understood disaster, which is specified in a slightly different way in each of the literary texts (Stefan Chwin’s autobiographical novel Krótka historia pewnego żartu [The brief history of a certain joke], a poem by Ryszard Kapuściński Na wystawie „Fotografia chłopów polskich do 1944 r.” [At an exhibition “The Polish peasants in photographs to 1944”] and Wisława Szymborska’s Fotografia z 11 września [Photograph from September 11]) – as death in a concentration camp, a general concept of the First World War or a terrorist attack. Upcoming tragic events – of which the photographed people are not yet aware – become for the subsequent recipient an inseparable element of reality contained in the frame. For the later observers, privileged with time perspective, the characters captured in the photograph are already victims of the catastrophe, which in reality was not yet recorded by the camera. It is a work about coexistence of the past and future in the field of photography.

Hydroponics is a way of intensification and a new paradigm of fodder production: from adaptive plant growing to operated cultivation of green mass of the set property. In a review the precondition of introduction of the alternative high-quality green foods "know-how" in completely controllable conditions are presented. Terms and definitions of the general concept and separate parts of hydroponic forage are given. Hydroponics makes for every day providing animals with the adequate quantity of high-quality forage. The hydroponics of forages allows to cultivate ecologically pure and organic product commercially, within economically defensible expenses. The synergy is shown and examples of zootechnical and economic efficiency are resulted.

The philosophy of knowledge is known as an established discipline both from Islamic perspective and Western viewpoint. Generally, it can be understood as a source of economy, power and prosperity. With the knowledge as a source of provider, the economic development, political power, business transaction and networking; rapid development in telecommunication and technology, with various other developments in human engineering and education plus, etc.‟s; human civilization flourishes.  Focusing on the philosophy of knowledge and comparing its traditional sense with modern practice might lead us to discover some ways in which knowledge should be realized, managed and applied. Obviously, the issue and criteria that determine what constitutes knowledge is indeed crucial. Therefore, this paper highlights general concept of knowledge management from Islamic perspective and its significant contribution to human development.

Structural degradation of the material upon long-term thermal and force impacts is a complex process which includes migration of the grain boundaries, diffusion of the active elements of the external and technological environment, hydrogen embrittlement, aging, grain boundary corrosion and other mechanisms. Application of the fractal and multifractal formalism to the description of microstructures opens up wide opportunities for quantitative assessment of the structural arrangement of the material, clarifies and reveals new aspects of the known mechanisms of structural transformations. Multifractal parameterization allows us to study the processes of structural degradation from the images of microstructures and identify structural changes that are hardly distinguishable visually. Any quantitative structural indicator can be used to calculate the multifractal spectra of the microstructure, but the most preferable is that provides the maximum range of variation in the numerical values of the multifractal components. The results of studying structural degradation of steel 15Kh5M upon continuous duty are presented. It is shown that structural degradation of steel during operation under high temperatures and stresses is accompanied by enlargement of the microstructural objects, broadening of the grain boundaries and allocation of the dispersed particles which are represented as point objects in the images. The processes of structural degradation lead to an increase in the range of changes in the components of the multifractal spectra. High values of complex indicators of structural arrangement indicate to an increase in heterogeneity and randomness at the micro-scale level, but at the same time, to manifestation of the ordered combinations of individual submicrostructures. Those structural transformations adapt the material to external impacts and provide the highest reliability and fracture resistance of the material.

Abstract: the discussion of this article aims to the use of vocabulary journal strategy in teaching vocabulary for the students of junior high school. The topic discussion will cover the general concept of learning vocabulary, principle of teaching vocabulary, teaching vocabulary in junior high school, and teaching vocabulary using vocabulary journal. Basically vocabulary journal is a strategy to invite students for strengthen their word knowledge and internalize meaning for use throughout their lives. It is a great strategy to help students’ vocabulary as naturally. Furthermore, some experts suggest that vocabulary journal can be applied in high school levels with different treatment depend on students’ needs and their English proficiency.

Abstract. Translating complex structures have always been a challenge for a translator since the structures can be densed with ideas and particular logical relations. The purpose of translation is reproducing texts into another language to make them available to wider readerships. Since language is not merely classification of a set of universal and general concept, that each language articulates or organizes the world differently, the concepts in one language can be radically different from another. One issue in translation is the difference among languages, that the wider gaps between the source and target languages may bring greater problems of transfer of message from the source into the target languages (Culler, 1976). Problematic factors involved in translation include meaning, style, proverbs, idioms and others. A number of translation procedures and strategies have been discussed to solve translation problems. This article presents analysis of complex structures in scientific Indonesian, the problems and effects on translation into English. The study involves data taken from two research article papers in Indonesian to be translated into English. The results of the analysis show seven (7) problems of Indonesian complex structures, whose effect on translation process can be grouped into two: complex structures related to grammar (including: complex structure with incomplete information, run-on sentences, redundancy , sentence elements with inequal semantic relation, and logical relation and choice of conjunctor) and complex structures related to information processing in discourse (including: front-weight- structure and thematic structure with changes of Theme element). Problems related to grammar may be solved with language economy and accuracy while those related to discourse may be solved with understanding information packaging patterns in the target language discourse. Keywords: scientific language, complex structures, translation
