HARMONIA AXYRIDIS ALOHTONA VRSTA NA PODRUČJU BOSNE I HERCEGOVINE

HARMONIA AXYRIDIS ALOHTONA VRSTA NA PODRUČJU BOSNE I HERCEGOVINE

Author(s): Mensur Zukić / Language(s): Bosnian Issue: 6/2013

Krajem oktobra i početkom novembra 2013. godine neke od država Balkana, pa tako iBosnu i Hercegovinu zahvatila je najezda skupine insekata iz skupine Coleoptera, poznatih pod nazivom božije ovčice ili bubamare (Coccinellidae). Ova pojava iznenadila je kako naučnike tako i stanovništvo koje se našlo u problemima zbog ovih insekata. Naučnici sa Univerziteta za poljoprivredu iz Zemuna naveli su 2 razloga, koja bi mogli da pojasne ovu pojavu koja desila u kasnu jesen 2013. godine :1. potraga za mjestom za hibernaciju; 2. neuobičajeno visoke temperature za ovo doba godine.

Влияние отходов химической промышленности на эколого-физиологические показатели бесхвостых амфибий из различных мест обитания

Author(s): A. M. Misyura,D. A. Spodarets / Language(s): Russian Issue: 2/2005

The influence of chemical enterprises’ sewage on the anurans populations led to the decrease of its number, the change of age structure and reduce of the age row. There was a change of organs’ morpho-physiological indexes under the influence of sewage. It is expressed, in one cases, in increase of the relative weight due to intensification of activity, but in other cases in the decrease of organs’ relative weight, that testifies to absence of adaptation to pollutants. These changes are expressed also in the decline of reproductive potential of the cenopopulations due to decrease of relative weight of the animals’ gonads.

Minor components composition of some types of surface lipids of some Coniferae were investigated. Among minor components of surface lipids the terpenoids of pimarane and abietane classes, squalene and p-coumaric acid were found.

FAUNA NYMPHALIDAE I PIERIDAE (LEPIDOPTERA) SJEVEROISTOČNE BOSNE

FAUNA NYMPHALIDAE I PIERIDAE (LEPIDOPTERA) SJEVEROISTOČNE BOSNE

Author(s): Isat Skenderović,Alen Bajrić,Zlatko Nedić,Jasmina Murtagić / Language(s): Bosnian Issue: 9/2017

According to the literature and the data obtained by analyzing the entomological collection of the Faculty of Sciences at the University of Tuzla,Department of Biology, the presence of diurnal butterflies was confirmed in several locations of north-eastern Bosnia. Entomological collection was created during field studies of butterflies by the students, and during the preparation of their graduation and master thesis. The identification of individual species was carried out with the help of the relevant identification keys. The analysis of the diurnal butterfly fauna, family Nymphalidae and Pieridae from northeast Bosnia showed the presence of 39 species of diurnal butterflies. Stated biodiversity of diurnal butterfly fauna of the study area is 2.3% of the total number of identified species in Bosnia and Herzegovina, which shows a very low degree of exploration of this area. There is very little written information about butterflies in this area.

ASPECTE BIOFIZICE ALE ACŢIUNII CÂMPURILOR ELECTROSTATICE ŞI ULTRASONICE ASUPRA MICROORGANISMELOR

Author(s): I. Gabriel Năstase,Dan C. Badea,Dragoş Ionuţ G. Năstase / Language(s): Romanian Issue: 26/2016

Living cells differ in electrical potential between inside and outside the cell, both in rest (membrane potential) and during cell (action potential). One of the most popular in terms of electrical behavior of cells, is to align the application of an electrostatic field, so much focused their direction becomes perpendicular to the electric current. Achieved through experience, has proved that high-voltage pulses can destroy microorganisms. Another effective way to destroy microorganisms is ultrasound. At certain values of the ultrasonic field intensity and duration of ultrasonic, can destroy the protozoa, bacteria, viruses.

Физиолого-гигиеническое обоснование нормы калия в питьевой воде: научно-практическое значение

Author(s): Roman Idelevich Aizman,Alexey Dmitrievich Gerasev,Oleg Aizman,Galina Ivanovna Krasheninina,Evgeny Mikhaylovich Trofimovich / Language(s): Russian Issue: 5/2018

Introduction. Recently there have not been physiological and hygienic investigations aimed at testing and clarifying optimal (OHN) and permissible (PHN) hygienic norms of potassium concentration in drinking water. The potassium concentration standard for drinking water of 12 mg / dm3, established by the European Community directive 98 / 83EC, has not been empirically investigated. Therefore, teaching this topic in the sections “Physiology of water-salt balance” and “Water supply hygiene” is not properly grounded. The aim of this work is to consider the physiology of potassium metabolism in the body and to experimentally justify hygienic norms of potassium concentrations in drinking water. Materials and Methods. To justify the hygienic norm of potassium content in drinking water, a physiological and hygienic approach based on the theoretical and experimental study of potassium homeostasis in the body of higher animals and humans, as well as on the analysis of physiological responses of the body to long-term dose-dependent effects of potassium loads was used. This made it possible to integrate the results of the study into the system of standards for this cation in drinking water. This physiological and hygienic approach to solving the problem became possible due to the long-term cooperation of researchers from Novosibirsk State Pedagogical University and Hygienic Research Institute, whose scientific developments in the field of physiology of potassium homeostasis regulation and water supply hygiene have received worldwide recognition. Results. It is shown, that regulation of potassium balance is provided as a direct influence of cation surplus on kidneys in the case of hyperkalemia, and the reflex mechanism which comes into action when potassium is absorbed from the digestive tract. This conclusion is based on the experimental data which prove that potassium-regulating reflex is presented by liver selective receptors, afferent vagal nerve pathways, the hypothalamic centres and hormones (renin-angiotensin-aldosterone system, vasopressin, insulin), causing changes in kidney functions – the main homeostatic organ, and potassium depot in tissues (skeletal muscles and liver).The second part describes the results of a 9-month chronic experiment in rats receiving drinking water with different potassium concentrations and its effect on kidney functions. It is shown, that potassium concentration of 5,0 mg/dm3 in drinking water did not cause changes in the renal response on water and potassium loadings in comparison with the control group (potassium concentration in drinking water was 1,0 ± 0,2 mg/dm3), whereas water with the potassium concentration of 50 mg/dm3 led to pressure of ionic balance regulation mechanisms in comparison with the control group. It was expressed in increase of potassium and sodium excretion after water loading and their decrease after potassium loading. Conclusions. The obtained data allow to conclude that a hygienic optimum of potassium ion concentration in drinking water is 1-5 mg/dm3, the threshold dose causing functional pressure of potassium regulation mechanisms is 50 mg/dm3, and the acceptable hygienic range of potassium in drinking water is 0,8–12,5 mg/dm3.

ДАРВИН МЕЂУ НАМА: ДАРОВАНИ СВЕТ НЕБРОЈЕНИХ ИСКУСТАВА

Author(s): Ljiljana Gavrilović / Language(s): Serbian Issue: 3/2010

This text discusses the impact of Darwin’s evolution theory on the change of perceiving the world during last 150 years, i. e. since the initial publication On the Origin of Species, as well as the reception of this theory in popular cultural production (novels, films, comics). Special attention is paid to ways in which Darwin’s theory and its general contribution to science are being treated in the system of primary education in contemporary Serbia – also, festivities commemorating the jubilee of the publication of On the Origin of Species in Serbia will be discussed.
