Authors: Prusty Jnyanendra Kumar , Pradhan Bulu 
Published: August 2022

Abstract
This study presents the application of Taguchi-grey relational analysis (GRA) to investigate the effect of control parameters on flowability, compressive strength, and sulfate and acid resistance of geopolymer mortar (GPM) simultaneously. The control parameters selected were ground granulated blast-furnace slag (GGBS) replacement (15 %, 30 %, and 45 %), water-to-geopolymer solids (W/GPS) ratio (0.31, 0.33, and 0.35), molarity of sodium hydroxide (NaOH) solution (10 M, 12 M, and 14 M), and sand-to-binder (S/B) ratio (1.5, 2, and 2.5). From the obtained results, GGBS replacement and the S/B ratio significantly influenced most of the studied properties of GPM. GPM prepared with a higher GGBS replacement showed higher compressive strength under ambient conditions, whereas GPM prepared with a lower GGBS replacement exhibited improved resistance against sulfate and acid attacks. From results of multiresponse optimization by Taguchi-GRA, GPM made with higher level of GGBS replacement (45 %) and molarity of NaOH solution (14 M), medium level of S/B ratio (2), and lower level of W/GPS ratio (0.31) exhibited better performance in most of studied properties simultaneously. Variations in peak intensity of compounds related to N-A-S-H and N-(C)-A-S-H gels formed in GPM were consistent with variations in compressive strength with ambient curing age as well as with variations in compressive strength of GPM exposed to sulfate solutions. Furthermore, a significant decrease in peak intensity of compounds related to aluminosilicate gels and in atomic Na/Si ratio and Al/Si ratio are in line with significant reduction in compressive strength of GPM when exposed to acid solutions that substantiate depolymerization of aluminosilicate gels in acidic environments.

Published: August 2022

Tocopherol is one of the known beneficial natural antioxidants ensuring the optimal level of functioning of mammalian organisms. Numerous in vitro and in vivo experiments have shown that the biological role of vitamin E is to prevent the development of pathologies caused by oxidative stress. In particular, the role of enzymatic factors of lipid peroxidation and related inflammation as a result of eicosanoid synthesis was clearly shown. We studied changes in the structural and functional state of hepatocyte membranes in the classical model of E-hypovitaminosis caused by long-term (70 days) insufficient intake of vitamin E in the diet of rats. The test components were determined spectrophotometrically after appropriate chromatographic procedures. The amount of total and individual leukotrienes was determined by ELISA. Prolonged tocopherol deficiency in rats caused a 49.4% decrease in tocopherol, more than 27.0% – in cholesterol. Of the 8 individual phospholipids studied, 6 showed significant changes: a decrease in cardiolipin and phosphatidylserine, and an increase in phosphatidylethanolamine by 3.24 times, an increse in lysophosphatidylcholine by 86.9%, in phospha­tidylcholine by 52.8%, and in sphingomyelin by 30.6%, relative to control. There were changes in the levels of unsaturated fatty acids playing a significant role in the development of functional disorders in cells and affecting the metabolism of ecosanoids derived from arachidonic acid by the 5-lipoxygenase oxidation pathway. Changes in the levels of total and individual cysteinyl leukotrienes in the state of E-hypovitaminosis were revealed. Restoration of vitamin E intake returns most of the studied indicators such as tocopherol, cholesterol, polyunsaturated fatty acids to the control levels and activates the processes of sequential conversion of leukotrienes in the body of rats. The obtained results indicate the potentiating effect of vitamin E on metabolic processes in the body as a whole and in hepatocytes and eicosanoid metabolism. The degree of tocopherol intake allows one to influence the course of inflammatory processes associated with eicosanoids, not only through the impact on precursors, but also on the utilization of metabolites, including leukotrienes.

Ten laboratory rats were experimentally invaded per os with the Eustrongylides excisus (Jäegerskiold, 1909) nematode larvae (L3–L4) received from Perca fluviatialis (Linnaeus, 1758), caught in the water area of the Dnipro-Buh Estuary, Ukraine. The aim of the experimental study was to measure the pathogenic effect of the given parasite on the mammals’ organisms by means of the histological analysis of the affected organs of the infected rats. The researched animals were divided into two groups. The experiment lasted 15 days; the second group was a control group. The histological analysis showed purulent-serous and purulent-fibrinous peritonitis, acute circulatory disorders in brain tissues (signs of hypoxic-ischemic lesions of the brainstem in the form of neuronal changes) and the heart (partial spasm of arteries and edema of interstitial myocardial tissue); pathological changes in the lungs (acute interstitial purulent pneumonia, acute focal emphysema of the lungs), liver (acute exudative hepatitis), kidneys (signs of shock reaction) and intestines (acute serous-purulent enteritis). Formation of non-specific granulomas was noticed, which contained the fragments of the parasitic larvae. The acute course of the purulent-serous and purulent-fibrinous inflammatory processes in the organs of the invaded rats was noticed; signs of systemic inflammatory response syndrome with pronounced distributive vascular leukocytosis in the studied organs.

Published: August 2022

Many countries are now facing the problem of increase in resistant biotypes of weeds. The spread of herbicide-resistant weeds across agrophytocenoses poses a threat of decrease in the effectiveness of use of herbicides in agricultural fields. In order to develop anti-resistant compositions of herbicides for protection of maize (Zea mays L.) crops, we studied effects of interaction and efficiency of weed control in greenhouse and field experiments. We studied the possibility of combined use of 4-hydroxyphenyl pyruvate dioxygenase-inhibiting herbicide tolpyralate and inhibitor of transport of electrons in photosystem 2 of chloroplasts – terbuthylazine – and acetolactate synthase-inhibiting rimsulfuron. In greenhouse experiments on model objects, we found that interaction in the mixtures of tolpyralate with rimsulfuron was antagonistic, but the antagonism may be overcome by increasing the rate of applied rimsulfuron. At joint use of tolpyralate and terbuthylazine, a synergistic increase in phytotoxic effect was observed, caused by increase in the effectiveness of the blocking electron-transport chain and increase in intensity of formation of reactive oxygen species. According to the results of the field experiments, we drew the conclusion that the efficacy of using the mixture of tolpyralate and rimsulfuron depends on the species composition of weeds. In the presence of rimsulfuron-resistant weeds, interaction with tolpyralate becomes antagonistic even in the conditions of increased rate of application of rimsulfuron, and thus the effectiveness of the protection significantly decreases. At the same time, after applying tank mixture of tolpyralate with terbuthylazine, the synergistic character of the interaction was maintained toward a broad range of species of grass and dicotyledonous weeds, providing high efficiency of maize crop protection. The herbicide compositions that were analyzed and are presented in the article allow one to decrease the possibility of emergence of resistant biotypes of weeds, and also to effectively control the already existing resistant biotypes.

Published: August 2022

The paper presents the peculiarities of morphological-anatomical structure of the organs, which are diagnostic traits of herbal raw materials (HRM) of the commonest species of Thymus L. genus in the moderate climatic zone. We determined that the studied species develop a subshrub life form, which grows monopodially in Th. pulegioides and Th. marschallianus, and sympodially with mono-, di- and polycyclic types of monocarpic shoots in Th. serpyllum. Inflorescence is of thyrsoid type with opposite partial inflorescences, which are constituents of simple dichasia with monochasia. Macroscopic and microscopic diagnostic features of the HRM are structure and pubescence on the stem, leaves and flowers, the anatomical structure of which was studied on 20 µm thick transversal sections using a light microscope. In Th. pulegioides, stems are tetrahedral, pubescent on ribs with unicellular and two-cellular elbow-shaped hairs. Leaves are ovoid, covered by multiangular epidermis that bears diacytic stromas, sharpened capitate unicellular and two-cellular hairs and 10–12 cellular essential oil glandules. In Th. marschallianus, the stems are poorly tetrahedral, rounded, pubescent on the entire surface. Leaves are elliptic, the cells of the epidermis are elongated, significantly tortuous, with 10–12 cellular glandules, diacytic stromas, capitate and unicellular hairs. In Th. serpyllum, the stems are cylindric, pubescent all round. The leaves are elongated-elliptic, epidermis cells are oval, tortuous, stromas are diacytic, essential oil glandules are 8–10 cellular, number of papilla-like hairs is low. The petioles and lamina base of the studied species are pubescent on the sides with short, coned and elbow-shaped, 2–3 cellular hairs, among which there are long, 4–8 cellular hairs; the hairs in Th. serpyllum are multicellular, interrupted. In mesophyll, there are schizogenous essential oil reservoirs. In Th. marschallianus and Th. pulegioídes, the calyx is campanulate, bilabiate, and pubescent. The flower corolla is purple-violet, bilabiate, has tube and outward bend, pubescent inside with coned unicellular hairs, has essential oil glandules and glandular capitate hairs, and pubescence in the fauces comprises long unicellular hairs. In Th. pulegioídes, cells of the corolla epidermis are multiangular-shaped with insignificantly wavy walls, in Th. marschallianus ‒ rectangular with significantly wavy walls. Cells of the tube epidermis are rectangular, tortuous. Surface of the corolla of Th. serpyllum is pubescent on both sides with short, cone-like and three-cellular, interrupted hairs, and also capitate hairs, and has essential oil glandules. Epidermis cells are multi-angular, tubes – rectangular and narrow. The obtained results may be used for diagnostics of HRM of morphologically similar species during their preparation.
From the forest to the coast: the wild meat trade chain on the Coast of Guyana

In the Caribbean region, very little is known about wild meat use and trade. To contribute to this knowledge gap, we studied the wild meat trade chain on the coastal area of Guyana, which geographically and culturally connects the Caribbean and the Amazon Region. In Guyana, the wildmeat sector is legal and in the process of being regulated. Our study shows that the market chain on the coast of Guyana is a short and direct market chain where the harvester most often sells directly to the consumer or through one level of intermediary (market vendors, home-based traders, roadside traders, restaurants, food stalls or rum shops). In coastal Guyana, wild meat can be considered a luxury, rather than a necessity: the price is higher compared to other alternative sources of meat and demand rises for special events. The topmost sold species are Cuniculus paca, Mazama americana, Tapirus terrestris, Dicotyles tajacu, Tayassu pecari, and Hydrochoerus hydrochaeris. The volumes traded to the coast of Guyana are equivalent to 361 tons of wild meat sold per year. Considering the population size on the coast of Guyana, this amount is equivalent to 1,4 g/capita/day and 4% of the protein intake from animal origin. These values are below those observed in urban towns from Central Amazonia in Brazil where wild meat consumption per capita equals to 18 g/capita/day. From a one health perspective, further attention is required with regards to food safety aspects along this legal trade chain.
Direction-dependent behaviour and size effect of steel fibre reinforced concrete based on the double punch test

Published: August 2022

AbstractThe post-cracking behaviour of steel fibre reinforced concrete (SFRC) is typically determined following an inverse analysis of flexural prism tests. Although these tests have significant practical merit, it has been argued that the anisotropy of the material due to the dispersion and orientation of the fibres cannot be accounted for in these tests. Multidirectional double punch tests on cubes have been proposed to overcome these issues. These tests are also well-suited to study size effects. However, no generally accepted inverse analysis method for these tests presently exists. This paper presents a simple and mechanically consistent inverse analysis procedure to estimate the residual post-cracking strength of SFRC from the results of double punch tests conducted on cubes. To explore the potential and limitations of this methodology, an experimental investigation was conducted on 30 double punch tests on cubes of varying sizes, varying fibre dosage and loading direction with respect to the concrete casting direction. The results demonstrate that the approach provides useful comparative information on the anisotropy of the material, however further investigation on the input parameters is required to prove its reliability in quantifying the residual tensile stress offered by the fibres.

The aim of this work was to study the cooperage potential of the oak species Quercus pyrenaica, which is widespread throughout the Iberian Peninsula. A red wine of 2016 vintage was aged in new barrels made from Quercus pyrenaica, Quercus petraea and Quercus alba for 12 months. This process was repeated with a similar red wine from the subsequent vintage using the same barrels in order to compare the performances of the new Q. pyrenaica barrels and Q. pyrenaica barrels that had been used for one year with equivalent Q. petraea and Q. alba barrels. The results indicate that Q. pyrenaica releases levels of β-methyl-γ-octalactone similar to those released by Q. alba and clearly higher than Q. petraea, whereas it releases levels of ellagitannins similar to Q. petraea and clearly higher than Q. alba. These data indicate that Q. pyrenaica is more similar to American oak from an aromatic point of view, since it provides mainly coconut notes, but is more similar to French oak in terms of wine structuration. Moreover, based on the preferences of a trained panel, the wines aged in the Q. pyrenaica barrels were ranked in second position, just behind the wines aged in the Q. petraea barrels and ahead of those aged in the Q. alba barrels. Consequently, Q. pyrenaica seems to have characteristics midway between the two most commonly used oak species for cooperage, confirming its high potential in this regard.
