Radon concentration in dwellings in the mining area of “Trepča” complex.
This paper presents the results of radon concentration in ground floor dwellings in the vicinity of the "Trepča" mine. Earlier studies on radon in the area of Kosovska Mitrovica have shown that there are dwellings with ...
New natural products from the epicuticular wax of Dianthus cruentus Griseb. (Caryophyllaceae)
Detailed GC and GC-MS analysis of a diethyl ether washings of fresh flowers of Dianthus cruentus Griseb. (Caryophyllaceae) enabled the identification of 153 constituents. The major identified compounds were long-chain ...
Antimicrobial activity of new mixed azines of coumarins and heteroaryl aldehydes
The azine functional group is a part of numerous compounds exhibiting a range of
pharmacological activities. As part of our continuous search for new pharmacologically
active compounds, we designed, synthesized, and ...
Antioxidant activity and acute toxicity of new unsymmetrical azines containing coumarin and one more heterocyclic moieties
During our previous work, we prepared a series of mixed azines with a coumarin moiety and
different benzaldehydes, and tested their acute toxicity and antioxidant activity. Since
heterocyclic compounds possess a broad ...
Small deformations, variations and energies of curves
Contrary to isometries as transformations that preserve distances, in-
finitesimal bending is a type of small deformation in which the arc length
is invariant with appropriate precision. The influence that given ...
Analysis of ecological territorial risk by methods of multidimensional statistics
В работе рассмотрены водные экосистемы как элементы единой социально природно-техногенной системы, предлагаемой для решения задач управления развитием промышленных территорий. Для оценки территориальных рисков водных ...
Some recent fixed point results of F-contractive mappings in metric space
The opinion is that the most important result in the metrical theory of
fixed points is the famous Banach contraction principle from 1922. It has been
generalized and extended in several directions. One of the most ...
Complex homogeneous differential equation of first and second order through iterations
The theory of complex differential equations represents an important mathematical discipline both from the theoretical point of view and from numerous applications. Its development was equally encouraged by mathematicians, ...
Number of zero solutions of some canonical complex differential equations of second order with variable coefficient
By solving the frequency function equation only a small number of complex equations of the second order oscillations can be solved. The simplest way is to observe canonical complex differential equations with constant ...
Zero search method for complex oscillating equation directly by direction
The problem of location of the zero solution of the second order complex oscillator equation for the given analytic function is unlikely to be completely solved. Therefore, estimates have long been resorted to. The easiest ...
