Author(s): V. S. Bilchuk,L. V. Shupranova / Language(s): Ukrainian Issue: 2/2005

The research results on influence of the by-product-coking industry emission on starch and saccharose accumulation in sprouts of the Acer L. species are presented. The toxic ingredients of the coke production wastes inhibit the process of starch hydrolysis that provokes considerable decrease of the sugars content and negative influence on the plants’ winter hardiness are established.

Author(s): A. A. Marchenkovskaya / Language(s): Russian Issue: 2/2005

Data of the research of two terrestrial amphibian species – common spade foot and green toad – from the territory adjoining to the Dnieper–Donbass channel are presented. The both populations are valid and stable. The high number of both young amphibians and mature individuals with high reproductive potential (high absolute reproductivity) are the affirmation. Morpho physiological indexes of the animals testify their normal physiological state. It has positive influence on the individuals’ and populations’ vital functions. The Dnieper–Donbass channel positively influences on the terrestrial amphibians by creation of new habitats and conditions for spreading.

Teória evolúcie z pohľadu filozofie (VI)

Author(s): Dušan Gálik / Language(s): Slovak Issue: 2/1997

Pokiaľ hovoríme o teórii evolúcie, nemôžeme obísť ani problém pôvodu a vzniku človeka. Vysvetlenie pôvodu a vzniku človeka predstavuje kontroverzný bod, v ktorom sa stretávajú vedecké, náboženské, filozofické, teologické i ideologické koncepcie, v ktorom sa naplno prejavujú najrozmanitejšie sociálne i kultúrne predsudky a vášne.

Teória evolúcie z pohľadu filozofie (V)

Author(s): Dušan Gálik / Language(s): Slovak Issue: 1/1997

Rovina sporov okolo existencie druhov v živej prírode poskytuje okrem teoretických problémov aj široké pole pre filozofickú diskusiu. Keďže ide, ako sme už povedali, o prípad diskusie o existencii univerzálií, aj tu môžeme vyznačiť dva hlavné smery chápania existencie druhov: realizmus a nominalizmus. Tieto majú, podobne ako vo filozofii, viacero podôb, odtieňov, typov, od striktných cez umiernené až po prechodné, nesúce znaky realizmu i nominalizmu.

Teória evolúcie z pohľadu filozofie (IV)

Author(s): Dušan Gálik / Language(s): Slovak Issue: 4/1996

Ako som uviedol už v prvej časti, biológia sa od tých vied, ktoré sú tradične vzorom exaktnosti, teda od fyziky a matematiky líši okrem iného tým, že vzhľadom na svoje ciele, metódy skúmania a spôsob opisu nemôže abstrahovať od kvalitatívnej rozmanitosti objektov, ktoré skúma. Kým napr. fyzika formuluje zákony, ktoré platia pre rôzne objekty bez ohľadu na to, aká je ich kvalitatívna určenosť, pre biológiu platia dve obmedzenia.

Devitt’s Promiscuous Essentialism

Author(s): Zdenka Brzović / Language(s): English Issue: 53/2018

In this paper I examine Michael Devitt’s version of essentialism, a view that stirred a lot of debate amongst philosophers of biology by going against the mainstream view of “death of essentialism” in evolutionary biology. So far, much more attention was directed to refuting Devitt’s view then to analyzing what his essentialism consists in. I go through the main tenets of the essentialist view, examine the relation between Devitt’s view and the so-called traditional essentialism, and the cluster approaches to natural kinds. I conclude that Devitt holds a very flexible variety of pluralistic essentialism, that I term promiscuous essentialism. The benefit of holding such a view is that it can encompass a wide range of categories, but its downside is that knowing the essence of a kind can be minimally explanatory. For this reason, the criterion for privileging certain kinds cannot follow from identifying their essence, which was originally one of the main motivations for holding an essentialist view.

Характеристики биоэлектрической активности головного мозга у студентов с ограниченными возможностями здоровья на фоне сочетания когнитивной и физических нагрузок

Author(s): Ksenya Valentinovna Davletyarova,Elena Vladimirovna Medvedeva,Natalia Andreevna Ovchinnikova,Galina Sergeevna Ezhova,Leonid Vladimirovich Kapilevich / Language(s): Russian Issue: 5/2018

Introduction. The article investigates mechanisms of physiological motor regulation and interaction of motor and cognitive activities in disabled people. The purpose of this study is to identify the characteristic features of brain bioelectric activity in students with visual or locomotor system disorders during cognitive and physical loads. Materials and Methods. The participants were students with special education needs, as well as healthy students aged between 18 and 20. They were divided into three groups. The first group consisted of students with locomotor system disorders (type 3 and 4 scoliosis); the second group consisted of students with visual disorders (high degree myopia); the third group (control) was represented by students attending physical education classes twice a week in the main group of health. The studies were carried out in two stages: the first stage (before physical activity) involved conducting a cognitive test followed by EEG recording. The second stage consisted of PWC170 test, followed by a cognitive test. Finally, bioelectric brain activity was examined by means of EEG method. Results. The results show that physical activity has a modulating effect on the cognitive sphere (in particular, on the function of attention and short-term memory) and on bioelectrical brain activity. The study indicated more significant effect on students with visual or locomotor system disorders than on healthy volunteers. In addition, the authors found that the nature, level and periodicity of physical activities, along with the formation of motor stereotypes, contribute to students' adaptation to educational activity. The authors analyzed the interrelation of psychophysiological characteristics, the effectiveness of cognitive activity and motor activity in students with disabilities and established approaches to managing the adaptation of students with special needs to conditions of inclusion by means of motor activity. Conclusions. The mutual influence of physical and cognitive activities is realized by means of developing specific activity patterns of the cerebral cortex, which is reflected in the peculiarities of bioelectrical activity.

Gęstościowe charakterystyki i równanie modelowe strumienia grawiosmotycznego

Author(s): Jolanta Jasik-Ślęzak,Andrzej Ślęzak / Language(s): Polish Issue: 2/2018

Density characteristics of the graviosmotic flux and the mathematical model of this flux, developed on the basis of Kedem-Katchalsky formalism are presented. Using this equation, calculations were made for a system of two membranes of cellulose acetate (Nephrophan) and aqueous solutions of KCl and ammonia. The obtained results indicate that the double-membrane system containing in the central compartment a ternary solution with a density equal to the density of water in the external compartments, can act as a gravitceptor.

SREDINA JESENI U SARAJEVU: NOĆNI ŠIŠMIŠ I DVOBOJNI ŠIŠMIŠ.

Author(s): Jasminko Mulaomerović / Language(s): Bosnian Issue: 50/2017

At the beginning of November 2017, a Common noctule bats (Nyctalus noctula) sounding was recorded in a building on Alipašino polje in Sarajevo. The building was previously known as a place of hibernation of this species during the winter. Later on, during the processing of the recording from the ultrasonic detector it is confirmed that this is the mentioned species. A few days later, the Common noctule bat was recorded on Vilsonovo šetalište near the Hotel Bristol. On the same recoding there were several weak, but by all characteristics recognizable signal of the social calls of the Parti-coloured bats. This is the first finding of this kind in Sarajevo.
