Abstract

On the basis of the obtained expeditionary data, the authors performed a comprehensive analysis of the ecosystems’ modern transformation in the studied area. In the course of the analysis, the authors found that at the present stage there have been quantitative changes (depletion of natural resources) in used landscapes, along with them, there are changes in qualitative characteristics (accumulation of resources). Now, against the background of vegetation and soil degradation, ways of their restoration are observed. New combinations of degraded and self-recovering ecosystems have emerged. Based on the analysis of the current state of different ecological systems and their relationships, the authors determined the possibilities of the dynamics of their combinations functioning by stages. This will make it possible to give a more reliable forecast of the ongoing processes in the ecosystems of the Republic of Kazakhstan.

Abstract

Lakes can be restored by the aeration method with the use of wind driven pulverising aerators. The method allows for moderate oxygenation of hypolimnion waters and it may be part of an integrated surface waters restoration system. The paper attempts to use the author’s method of maximum wind speeds to assess the volumetric flow of water through the aerator pulverisation mechanism. The study was conducted in 2018 in windy conditions of Lake Swarzędzkie. The introduction to the paper includes the characteristic of the lake and discusses the construction and operation of the wind driven pulverising aerator. Based on the maximum wind speed model, the theoretical capacity of the machine was calculated, which in the conditions of Lake Swarzędzkie was less than 111,500 m3 per year. Based on maximum wind speeds, the method of assessing the efficiency of the wind driven pulverising aerator is suitable for determining the volumetric flow rate of the pulverisation unit. This can significantly facilitate the planning of water reservoir restoration.

Abstract

The paper discusses the current prognoses of aquaculture development worldwide putting an emphasis on its effect on the environment and the issue of the protection of water reservoirs in different countries. Water consumption in diversified aquaculture systems is presented herein as well as the characteristics of the mechanical and biological water treatment methods in fish farms, with particular attention paid to the recirculating water systems. New aquaculture technologies using post-production waters are presented. The paper provides a discussion on the contribution of aquaculture to the global greenhouse gas emissions and the means of limiting this emission. The effect of climate change on aquatic ecosystems is presented in the context of the changes of the aquaculture production profile. The paper includes a brief presentation of the methods of mitigating the changes with respect to contamination of aquatic ecosystems as well as climate change. Reducing the water footprint can be achieved through selective breeding, species diversification and implementation of more technologically advanced aquaculture systems such as: integrated multi-trophic aquaculture, aquaponics and recirculation systems in aquaculture. The need for certification of fish farms with water recirculation systems is justified in the paper. The issues addressed herein are summarised and the main areas for extending the research promoting preservation of aquatic ecosystems in aquaculture are presented.

Abstract

In this study, the removal of imidacloprid (IMD) pesticide onto activated carbon produced from nut shells of hazelnut (HAC), and walnut (WAC) has been investigated. The prepared activated carbons were characterised by total carbon, nitrogen and hydrogen content, surface areas and pore volume. Fourier-transform infrared (FTIR), and scanning electron microscopy (SEM) were studied before and after adsorption experiments. Effects of adsorbent dose (0.02–0.2 g), contact time (10–120 min), initial imidacloprid concentration (10–100 mg∙dm ^–3), and pH (1–8), and temperatures (25–50°C) on the removal of IMD pesticide by HAC and WAC in the batch mode were studied. The removal percentage of imidacloprid pesticide by HAC and WAC was 93.79% and 94.72%, respectively. The study showed that the pseudo-second-order kinetics model fitted well for both activated carbons. Moreover, adsorption isotherm results were evaluated using Freundlich, Langmuir and Temkin isotherm models. The adsorption results correlated well with the Langmuir isotherm model ( R² = 0.987 and 0.964) with maximum adsorption capacities of 76.923 and 83.333 mg∙g ^–1 for HAC and WAC, respectively, and an equilibrium time within 120 min. The nature of the adsorption of imidacloprid pesticide onto HAC and WAC is exothermic, spontaneous and physical in nature. The two prepared activated carbons (HAC, WAC) were successfully regenerated for three cycles and could be used as an effective and low-cost adsorbent for the removal of IMD pesticide from aqueous solutions. The production of the activated carbons of HAC and WAC will provide minimisation of these wastes in the environment.

Abstract

The study area is located in the North-Eastern part of the Nile Delta, northern of Ismailia canal and western Suez Canal. It comprises an area of about 3,058.8 km2 (728,285.38 feddans). This work aims to identify the main physiographic units and its features, as well as emphasise the importance of combining soil taxonomy (2014) and WRB classification (2022) systems.
Two main physiographic units were distinguished in the study area according to the previous studies, interpretation of satellite image and digital elevation model (DEM) as well as field observations; the first consists of fluvio-marine flats and the second river terraces which include the fluvial and deltaic origin.
According to field morphological descriptions as well as chemical and physical analyses, representative profiles are classified by using both Soil Taxonomy and WRB systems. The current study is the third manuscript to emphasise the importance of using both systems together in order to obtain maximum possible characteristics of the earth. Below are examples that illustrate this importance.
Soils of profile No. 4 which represent the fluvio-marine soils are classified according to soil taxonomy as follows: Typical Haplosalids, fine silty, mixed, thermic.
While these soils are classified according to WRB as follows: Fluvic Sodic Solonchaks (Siltic/Loamy/Clayic, Chloridic, Evapocrustic, Ochric, Hypersalic).
Soils of gypsiferous which represent soils of profile No. 6 are classified according to Soil Taxonomy as: Gypsic Aquisalids, loamy over sandy, mixed, thermic, whereas the application of the WRB system reveals the following: Fluvic Calcic Gypsic Sodic Gleyic Solonchaks (Loamic, Chloridic, Hypersalic).

Abstract

In his book, Ajuar funerario (2004), Fernando Iwasaki presents a range of scary stories. In some cases, the horror results from the gap between the terrible story told or suggested and the tone of the narrator. Although the presence of intertextual references to canonical authors of the genre often leads to parody, laughter, or smile never last long in Iwasaki’s literature. The reader soon realizes that even if horror has ceased to be embodied in the traditional motifs of the genre, it is still there, alive and kicking, ready to put our certainties in crisis and give us new chills.

Abstract

Manuel de Lima (1915–1976), violinist, painter and music critic, began his writing career in 1944 with the long short-story Um Homem de Barbas [ A man with a beard]. It was the middle of the Second World War and the Salazar dictatorship was well established in officially neutral Portugal. A few years before the belated emergence of Portuguese surrealism, to which he was linked, and in the midst of the development of neorealism, a protest movement followed mainly by the young writers of the time, Manuel de Lima asserted himself from the outset as a very singular writer. Um Homem de Barba is a narrative of a love triangle that ends with the spectacular disappearance of the three protagonists. In this first work placed under the sign of the absurd, which mixes satire, marvelous, and burlesque and in which, according to Almada Negreiros' 1944 preface, the author uses realism to "undo realism", we will study the place and role of humor, as well as the various devices used.
