Construction and techniques of writing a scientific paper in natural and engineering sciences
In science and scientific research there is a wide spectre of fields and
subfields which are not always strictly confined. Different classifications
of sciences are also known. Numerous books have been published regarding
scientific research, types of scientific papers and manners in which their
results are published. This literature is very detailed and precise within
international academic circles, especially the literature that relates to
publishing scientific books and doctoral theses. However, there are certain
dilemmas and inconsistencies which can confuse a young scientist when
writing an original research article. After a brief review of issues
pertinent to scientific paper writing, methodology of scientific research and
type of papers, this paper shows characteristics and construction of an
original research article. It shows a technique of writing a paper in all
scientific fields and subfields with special emphasis on natural and
engineering sciences and in accordance with international and domestic
standards. Wider practical guidelines can be found in the cited literature,
so they can be additionally used, if needed. [Projekat Ministarstva nauke

Enzymatic oligomerization and polymerization of arylamines: state of the art and perspectives
The literature concerning the oxidative oligomerization and polymerization of various arylamines, e.g., aniline, substituted anilines, aminonaphthalene and its derivatives, catalyzed by oxidoreductases, such as laccases and peroxidases, in aqueous, organic, and mixed aqueous organic monophasic or biphasic media, is reviewed. An overview of template-free as well as template-assisted enzymatic syntheses of oligomers and polymers of arylamines is given. Special attention is paid to mechanistic aspects of these biocatalytic processes. Because of the nontoxicity of oxidoreductases and their high catalytic efficiency, as well as high selectivity of enzymatic oligomerizations/polymerizations under mild conditions-using mainly water as a solvent and often resulting in minimal byproduct formation-enzymatic oligomerizations and polymerizations of arylamines are environmentally friendly and significantly contribute to a "green'' chemistry of conducting and redox-active oligomers and polymers. Current and potential future applications of enzymatic polymerization processes and enzymatically synthesized oligo/polyarylamines are discussed

The genetic history of the Southern Arc: a bridge between West Asia and Europe
By sequencing 727 ancient individuals from the Southern Arc (Anatolia and its neighbors in Southeastern Europe and West Asia) over 10,000 years, we contextualize its Chalcolithic period and Bronze Age (about 5000 to 1000 BCE), when extensive gene flow entangled it with the Eurasian steppe. Two streams of migration transmitted Caucasus and Anatolian/Levantine ancestry northward, and the Yamnaya pastoralists, formed on the steppe, then spread southward into the Balkans and across the Caucasus into Armenia, where they left numerous patrilineal descendants. Anatolia was transformed by intra–West Asian gene flow, with negligible impact of the later Yamnaya migrations. This contrasts with all other regions where Indo-European languages were spoken, suggesting that the homeland of the Indo-Anatolian language family was in West Asia, with only secondary dispersals of non-Anatolian Indo-Europeans from the steppe
