Authors: Sabadash V. , Gumnitsky J. , Lyuta O. , Hyvlyud A. 
Published: April 2021

Abstract
Wastewaters from dairy processing factories contaminated with α-oxypropionic acid were monitored. Theoretical analysis of industrial wastewater treatment methods on zeolites of Sokyrnytsia deposit was carried out. The process of sorption of α-oxypropionic (α-oxypropionic) acid by natural zeolite of Sokyrnytsia deposit was considered. It was established that the most economically advantageous and safe is the method of adsorption using a natural sorbent - zeolite, which provides the lowest concentration of contaminants in treated wastewaters from dairies. An assessment of their number, localization features and measures of toxicological impact on the environment was done. The existing theoretical apparatus of description of adsorption processes was analyzed. The sorption properties of natural zeolite (clinoptilolite of Sokyrnytsia deposit) and activated carbon to α-oxypropionic acid were tested. Equilibrium values of adsorption capacity were calculated and corresponding isotherms at a temperature of 20 ° С were constructed. The porosity of the sorbent and its influence on the sorption properties were studied by the methods of physicochemical analysis. Infrared spectroscopic and electron microscopic studies confirmed the presence of the process of sorption by the surface of the internal pores of the zeolite of α-oxypropionic acid molecules. Experimental studies have confirmed the possibility of using natural zeolite for wastewater treatment of dairy factories. It was experimentally confirmed by physicochemical methods of analysis (electron microscopy, IR spectroscopy, microprobe analysis, mercury porometry) and was established that the process takes place both by the mechanism of ion exchange and physical adsorption. The content of carbon radicals in the zeolite matrix after the sorption process was confirmed by X-ray spectral microanalysis. The ability of zeolite to adsorb organic carboxylic acid radicals was confirmed by the results of IR spectroscopic studies. On the IR spectra there are strips of deformation and valence oscillations of the groups of the crystal lattice of the zeolite Si-O, Si-O-SiOH: 452, 990–1210, 1638, 3368 cm−1. The oscillation spectra of free OH groups in the region of 2600 cm−1 were revealed.

Published: April 2021

Abstract
This investigation was aimed to study the effect of Pinus halepensis aqueous bark extract and zinc to prevent indomethacin induced gastric ulcer in rats. Thirty female albino Wistar rats were divided into 6 groups of 5 animals each (n=5); Group 1: normal control, Group 2: ulcer rats received normal saline, Group 3: ulcer rats treated with P. halepensis, Group 4: ulcer rats were treated with zinc, Group 5: ulcer rats were treated with P. halepensis + zinc and Group 6 ulcer rats were treated with Ranitidine for 15 days. Stomach ulcer was induced by a single oral administration of indomethacin (30 mg/kg). Various biochimical, physiologic and histologic parameters were estimated. Obtained results show that the ulcer index, pH and total acidity level were significantly reduced (p<0.05) and Pepsin activity was significantly increased (p< 0.05) in ulcer induced rats pre-treated with extract of P. halepensis, zinc and ranitidine when compared with indomethacin treated rats. The MDA level was significantly decreased and GSH level was increased (p< 0.05) in rats treated with plant extract and zinc. Histopathology of gastric mucosa confirmed the gastro-protection by plant and zinc treatment. The study reveals anti-ulcer and antioxidant properties were observed in bark aqueous extract of P. halepensis groups with a benefic effect of zinc to reduce oxidative stress and gastric ulcer induced in the rat.

Published: April 2021

Abstract
Romania has many mineral water sources due to its geological features. In the present study, bottles of 26 Romanian mineral water brands were purchased from the market to make a characterization based on the pH, conductivity, and fixed residue content. Focusing on the total fixed residue, the distribution of low, medium, and highly mineralized water was 43.9%, 41.46%, and 14.63% respectively. The mean of fixed residue concentration was 763.3 mg/L, ranging from 40.37 mg/L to 2,603 mg/L. The pH values of the still mineral waters varied between 6.86 and 7.91, while the pH values of the sparkling mineral waters were the lowest (4.7). The conductivity was strongly related to the concentration of the ions, so the maximum measured conductivity for the still waters was 573 μS/cm, for the partially sparkling waters 2,133 μS/cm, and for the sparkling mineral waters 3,079 μS/cm. The chemical composition of the mineral waters was highly dependent on the rock types. Using the hierarchical cluster analysis, two different clusters were detected according to the main characteristics of mineral waters.

Authors: Bensaci Oussama Ali , Beghami Riadh , Gouaref Kamel 
Published: April 2021

Abstract
Anthracnose of holm oak (Quercus ilex L.) was studied in several sites located in Belezma National Park (Eastern Algeria). Disease severity varied according to the site, but symptoms were particularly frequent on leaves supported by south-facing twigs. Leaves inserted on the distal part of twigs were more affected by anthracnose regardless of twigs’ position on trees. The fungal isolates obtained from damaged tissues were sorted to five morphotypes and identified as Apiognomonia errabunda based on morphological characteristics and ITS sequencing. This is the first record of the occurrence of the fungus Apiognomonia errabunda on Quercus ilex in Algeria. Particular climatic conditions marked by late spring rains followed by high temperatures may play a key role in the increased leaf vulnerability of Q. ilex to infection.

Authors: Li Huawei , Wang Guifang , Jombach Sándor 
Published: April 2021

Abstract
Most of the urban heat island (UHI) researches focused on the phenomenon in summer. They mainly studied the causes, different functional areas, and possible mitigation measures to reduce the high temperature in urban areas. However, UHI also exists in winter, but there are a limited number of studies on winter UHI. The characteristics and causes of UHI in winter have not been received much attention or consideration yet. This study aims to characterize the UHI feature in winter in Budapest, Hungary, based on the analysis of land surface temperature (LST) in relation to the factors of elevation, slope exposure, residential type, and snow coverage. Five different Landsat images in the winter season were applied to detect the surface temperature; besides, pictures of the thermal camera at a micro-scale were also used. Results showed that UHI intensity was not strong in winter; built-up areas were warmer than other urban areas. Topography was one of the significant factors affecting the surface temperature in winter. The surface temperature of the hills (300 m asl) was lower than that of the lowlands (below 120 m asl). The south-facing slopes and south oriented buildings were warmer than north-facing slopes and buildings oriented to the north. Areas with snow coverage had a lower temperature than no snow coverage areas. These findings could give general guidance for further UHI research, urban planning as well as landscape design.

Progressive development and risk analysis of rock avalanches: a case study in Higher Himalayan Crystallines of the Langtang National Park, central Nepal
Authors: Weidinger J. T. 
Published: April 2021

Basic research work on the rare phenomenon of the Tsergo Ri mass movement in the Upper Langtang valley (Nepal Himalaya) during 1990-1996 has helped to identify the most important causes of this extraordinary event (Weidinger et al., 1996). Further investigations all along the valley revealed the preexisting structures in the crystalline rocks of the Higher Himalayan sequence that are also responsible for smaller but frequent landslides and/or rock avalanches (Weidinger, 1997).
Dynamic geomorphological changes are the result of weak rock behavior due to mechanical conditions of different lithology and seismotectonic structures. Rejuvenations of landslides and rockfalls are frequent as well. They often show a progressive development and/or continuous activity.
Keeping in mind the preexisting structures of the Tsergo Ri landslide, which have been described as brittle reacting leucogranite dykes, metamorphites with deformational fabrics, sulphide ore and neotectonic structures, four recently occurred rockavalanches (typical for the Langtang Valley) were investigated: one in the right side of the recent Langtang valley glacier (Langtang Tsang), about 2 km north of the Alp Pangri Goldum, one in the area of the broken crest of the Tsergo Ri mass movement, west of the glacier named Kyimoshung Tsang (both in the Upper Langtang Valley) and two more in the Lower Langtang valley, south of the "Landslide Lodge" and north of the "Lama Lodge".
Studying these phenomena from the geological and tectonical point of view, geomorphologic changes, morphodynamic development and triggering factors during a period of six years, made it possible to analyse future-risk for some parts of the area.
