Optimization of selection of tasks or questions assigned to different subjects from a larger set of tasks is a problematic topic, often solved not only in schools. The article presents the principles and original algorithmic ...
The purpose of this review is to discuss rare neurological disorders with respect to communication difficulties typical of children. Firstly, communication disorders with special focus on rare communication neurological ...
In time of climate change, close-to-nature silviculture is growing in importance as a tool for future forest management. The paper study the tree layer and natural regeneration of monospecific Norway spruce (Picea abies ...
Coffee, one of the world's most consumed products, is extracted from the roasted seeds of Coffea sp., a plant native to Africa. The effects of coffee on the human body have been recognized for centuries and have now become ...

Platinum complexes have been studied for cancer treatment for several decades. Furthermore, another important platinum characteristic is related to its chemical shifts, in which some studies have shown that the Pt-195 ...
In this paper, we study a higher order generalization of the Jacobsthal sequence, namely, the (k,c)}-Jacobsthal sequence (Jn(k,c)) for any integers n, k >= 2. In particular, we find information about roots of its characteristic ...
Certain AChE reactivators, asoxime, obidoxime, K027, K048, and K075, when taken in overdoses and sometimes even when introduced within therapeutic ranges, may injure the different organs. As a continuation of previously ...
Background: Teleost fish genome size has been repeatedly demonstrated to positively correlate with the proportion of transposable elements (TEs). This finding might have far-reaching implications for our understanding of ...

Casualties caused by organophosphorus pesticides are a burden for health systems in developing and poor countries. Such compounds are potent acetylcholinesterase irreversible inhibitors, and share the toxic profile with ...
Let Fn be the n-th Fibonacci number. Order of appearance z(n) of a natural number n is defined as smallest natural number k, such that n divides Fk. In 1930, Lehmer proved that all solutions of equation z(n)=n+/-1 are prime ...
The paper deals with a research focused on the blended learning model represented by an online component MyEnglishLab complementing English paper-based materials. At first, we viewed the blended learning model and we ...
The structure of forests is an important stabilizing factor regarding ongoing global climate and land use change. Biodiverse mountain forests with natural structure are one of the ecosystems most endangered by these problems. ...
Recently a lot of papers were devoted to partial infinite reciprocal sums of a higher-order linear recursive sequence. In this paper, we continue this program by finding a sequence which is asymptotically equivalent to ...
Nuclear ribosomal RNA (rRNA) genes represent the oldest repetitive fraction universal to all eukaryotic genomes. Their deeply anchored universality and omnipresence during eukaryotic evolution reflects in multiple roles ...

Six quinoline-piperonal hybrids were synthesized and evaluated as potential drugs against Alzheimer's disease (AD). Theoretical analysis of the pharmacokinetic and toxicological properties of the compounds suggest that ...
This paper describes the design of a low-cost radon detector that can easily be fabricated in large quantities for the purposes of earthquake prediction. The described detector can also be used for monitoring radon levels ...
Modern technologies are getting involved in most spheres of human activities, they play an important role also in cultural heritage care. These technologies are used when research into historical reference is carried out, ...
Tea (Camellia sinensis) plants inhabit arbuscular mycorrhizal fungi (AMF) in rhizosphere, whereas it is not clear whether AMF improves leaf food quality of tea plants. A potted study was conducted to determine effects of ...
Forest plantations are still often considered the antithesis of real nature. However, plantations can host many organisms. The problem is that some of the hosted species are regarded ad hoc as pests. The main aim of our ...
