Academic literature on the topic 'Chechen imprints'

The purpose of the research is a commission test of the efficacy of the supramolecular complex of ivermectin at gastrointestinal strongylatoses of horses.Materials and methods. The commission experiment was performed in June 2019 in the North Caucasian Federal District of the Chechen Republic. The efficacy of the supramolecular complex of ivermectin was evaluated on 20 horses of different breeds in the Seradin Equestrian Center. To determine the rate of gastrointestinal nematode infection in horses, we collected fresh feces in the morning, made tissue imprints from perianal folds and examined them by the Fülleborn's method using a saturated solution of sodium chloride.Results and discussion. The coproovoscopic examination determined a 100% infection of horses with Strongylates and 40.0% infection with Oxyuris sp., with 488.7±24.4 strongylates eggs and 16.9±0.84 Oxyuris sp. eggs found in 1 g of feces, respectively. Seven and 15 days after the supramolecular complex of ivermectin administered to the horses from the first test group at a dose of 0.15 mg/kg for the active substance (7.5 mg/kg for the drug) in a mixture with mixed feed, we did not find any Strongylata eggs or Oxyuris sp. eggs in feces or on tissue imprints. Insufficient efficacy was obtained in the horses from the second test group after being treated with the active substance of ivermectin at a dose of 0.15 mg/kg. The strongylate egg number decreased on average by 244.3±12.21, namely, by 50.1%, and no Oxyuris sp. eggs were found. The efficacy against Oxyuris sp. was 100%. The horses consumed the mixture of drugs with feed readily. There were no side effects after the drugs applied. Thus, we established the high efficacy of the supramolecular complex of ivermectin against gastrointestinal strongylatoses, and the convenience of its use in a mixture with feed to untamed herd horses individually and by group feeding.

This paper presents an approach to fabricate nanoscale gratings by direct imprint on silicon substrate. Imprint conditions that affect the transcription accuracy, such as imprint temperature and pressure, are discussed, and the profile of the imprinted 80nm width gratings with a 250 nm pitch is checked by SEM. High fidelity and fine uniformity demonstrate that nanoimprint is an economical and efficient method to fabricate nanoscale gratings.

ABSTRACT Objectives: To experimentally evaluate the efficacy of a standard sterilization protocol employed during reuse of disposable helical stone baskets. Methods: Study performed on 20 helical stone baskets: 10 were used in the initial validation process, contaminated with Escherichia coli ATCC 25922 and imprinted on Müeller-Hinton media; 10 catheters were contaminated with Geobacillus stearothermophilus ATCC 7953, processed, inoculated in TSB and incubated in a water bath at a temperature of 55°C. Bacterial growth was evaluated after 1, 3, 5 and 7 days. After sterilization, stone baskets were also opened and closed 40 times to check for functional problems. All plastic and basket parts were carefully checked for damages. Results: After the 72-hour incubation period, there was growth of E. coli ATCC 25922 in 100% of imprints. After the sterilization process and up to 7 days incubation period on a blood agar plate, there was no growth of G. stearothermophilus ATCC 7953 or any other bacteria. There were no functional problems or damage to baskets after the sterilization process. Conclusion: The ethylene oxide system is efficacious and safe for sterilization of disposable helical stone baskets. However, further clinical studies are required and should provide more safety information.

Цифровые преобразования региональных социально-экономических систем определяют долгосрочные тренды экономического роста и финансовой стабильности отдельных территориальных образований. Глобальные тенденции по «оцифровке» экономических и финансовых отношений накладывают свой отпечаток на вектор регионального развития национальных экономик. Подобные вопросы являются актуальными в том числе и для России. В этой связи данная статья направлена на выявление особенностей и проблем в процессах цифровизации региональной банковской системы и рынка банковских услуг по показателям диджитализации и финансовой доступности Чеченской Республики. Рассмотрена необходимость и основные факторы цифровой трансформации обособленной экономики. Определены понятия цифровые финансы и финансовая доступность, а также отражена связь между данными сферами в современных условиях. Проанализированы показатели информатизации Чеченской Республики. Также проведена оценка обеспеченности Региона банковскими услугами. Выявлена степень взаимосвязи между индикаторами информатизации региона и уровнем цифровизации рынка банковских услуг с точки зрения доступности сети Интернет и развитости дистанционного банковского обслуживания. Digital transformations of regional socio-economic systems determine long-term trends in economic growth and financial stability of individual territorial entities. Global trends in the “digitization” of economic and financial relations impose their imprint on the vector of regional development of national economies. Such issues are also relevant for Russia. In this regard, this article is aimed at identifying features and problems in the digitalization processes of the regional banking system and the banking services market in terms of digitisation and financial accessibility of the Chechen Republic. The necessity and main factors of digital transformation of isolated economy are considered. The concepts of digital finance and financial accessibility are defined, as well as the connection between these areas in modern conditions. Indicators of informatization of the Chechen Republic were analyzed. The Region’s banking services were also assessed. The degree of interaction between indicators of informatization of the region and the level of digitalization of the banking services market in terms of Internet accessibility and the development of remote banking services was revealed.

This article analyzes how Moscow has extended its rule over Chechnia since the beginning of this century. Within the larger understanding of this rule as imperial in form, the current distinct contractual relationship between the Russian center and Chechnia is substantiated as one based on kinship. I argue that the Putin-Kadyrov relationship is a generic case of patronage but highlight the local imprint that such relations acquire by tracing how Chechen kinship practices inform this case.

The article is devoted to the study of sacred symbols represented in the petroglyphs of Chechnya and widely used in the material culture of the local population of the ancient and late medieval era: in the decoration of metal products, the ornament of carpets and ceramics. The author believes that sacred symbolism is reflected in spiritual culture. The circle, the cross, the spiral and other sacred symbols have been embodied in a variety of forms in oral folk art, dance culture, ritual traditions, the Nart epic, thereby defining the stylistic features of the culture of the North Caucasus. Sacred meanings are imprinted not only in the images of dancing anthropomorphic figures on the walls of residential and combat towers, but also the pattern of their movements and gestures repeats the outlines of ancient symbols, thereby testifying to the ritual nature of the origin of folk dance and many genres of oral folk art. The methodological basis of the research is a set of general historical, ethnographic and archaeological research methods, the use of which is determined by the nature of the material being studied. Thus, the internal space and structure of the phenomena of spiritual culture correspond to the forms of the main sacred symbols that existed in the culture of the peoples of the region in ancient times, thereby creating a special style of North Caucasian culture, which is characterized by inner sacredness. The reflection of mythological plots and symbols in petroglyphs and bronze plastics of the Koban culture of late Bronze and early iron testifies to the deep antiquity of folk dance and many genres of oral folk art of the population of the North Caucasus and speaks about the close intertwining of the phenomena of material and spiritual culture in that period, about the sacredness of being in its representations. Ritualism penetrates into all spheres of life (labor, funeral rite, wedding ceremony), protecting the ancient man from all bad things.

tudy of philopatry and dispersal of pied flycatchers Ficedula hypoleuca was launched on the Courish Spit (SE Baltic) in 1981. Since then, ca. 9,000 nestlings were ringed at different sites in the Russian part of the Courish Spit. A total of 557 individuals ringed as pulli were recaptured in subsequent seasons in the study area. Both males and females are more often recaptured in the plots where they were ringed than in other plots. These results were interpreted in the framework of the hypothesis forwarded by Löhrl (1959) and supported by Berndt & Winkel (1979). These authors suggested that cavity nesters (pied flycatchers and collared flycatchers F. albicollis) imprint their future local breeding area during the period of postfledging exploration. Birds that survive until the next spring, return to these imprinted areas to breed. A similar study done by Sokolov et al. (1984) on the Courish Spit in an open nesting species, the chaffinch Fringilla coelebs, confirmed this finding. We assumed that juvenile pied flycatchers disperse for varying distances during their postfledging movements and imprint a local area, some 1–5 kilometres in diameter. This area is the goal of their migration next spring. It is suggested that in spring, yearlings are non–randomly distributed in respect to the area they have imprinted as juveniles. Recently, Vysotsky (2000, 2001) re–analysed the same data on philopatry of pied flycatchers on the Courish Spit and forwarded an alternative hypothesis. He suggests that juveniles, both males and females, do not imprint any local area during the postfledging period, but are distributed randomly across the area of several dozens of kilometres in spring. Vysotsky was able to show that distribution of distances of natal dispersal did not differ from the random pattern the study plot which was an 8.5 km long line of nest boxes along the Courish Spit. The aim of this study was to test these two alternative hypotheses. To do so, we set up nine new study plots in 2000. Over 800 nest–boxes were made available for the birds (in addition to the old 400) in the 44 km long area. We recaptured pied flycatchers returning for breeding during four years, 2000–2003. The distribution of natal dispersal distances was compared with the null model which assumes that pied flycatchers settle randomly in the study area. We took all nest boxes from which pied flycatchers successfully fledged in a particular year and all next boxes where we were able to capture either a male or a female in the subsequent year, and calculated the distances between each pair of such nest boxes. Simulations were run separately for each sex. Theoretical distributions already include control efficiency. If some nest boxes were not checked in some year, or if we failed to capture one or both members of a breeding pair, we did not include this nest box inthe model. Some birds could settle outside the study plot. Therefore, the theoretical distribution may underestimate the actual range of natal dispersal, but is unlikely to overestimate it. The number of females ringed as nestlings and recaptured as one–year–old birds was 43. The distribution of their natal distances (mean 6,8 km, SE = 0,81; median 5,4 km) was not significantly different from the pattern predicted by the null model (Wilcoxon matched pairs test: z = 1,25; p = 0,21). Conversely, males settled significantly closer to their natal nest box (n = 83; mean 4,3 km, SE = 0,57; median 2,5 km) than predicted by the model (Wilcoxon matched pairs test: z = 2,45; p = 0,014). For example, 24% of males settle within one km from their natal site, as compared with 7% predicted by the model. Males are found with a greater than chance probability within the 7 km zone around their natal site. The hypothesis by Vysotsky (2000) can thus be rejected for pied flycatcher males. Pied flycatcher females are known to settle at larger distances from their natal nest box. The very fact that were controlled 83 males and only 43 females suggests, assumed that sex ratio at fledging is close to being equal and that true survival rates during the first year of life do not differ greatly between the sexes, that many females emigrated from of our study plot. This does not mean that juvenile females do not imprint a home area during the postfledging period, as suggested by Vysotsky (2000). We think that the reason for this is not the inadequate navigational ability of the females but the fact that they were attracted by a prospecting male at some distance from their migratory destination and settle there. Such intercepting was suggested by Fedorov (1996) for Acrocephalus warblers, and it may exist in other migratory passerines. This is supported by the data on natal site fidelity from Spain which show that in Spanish pied flycatcher populations, recruitment rate did not differ between female and male juveniles (Potti & Montalvo, 1991). Females from these southern populations have a limited chance to be attracted by prospecting males in even more southern areas.

In this paper, an electrochemical sensor for epinephrine (EP), a neurotransmitter was developed by anchoring molecularly imprinted polymeric matrix (MIP) on the surface of gold-coated quartz crystal electrode of electrochemical quartz crystal microbalance (EQCM) using starch nanoparticles (Starch NP) — reduced graphene oxide (RGO) nanocomposite as polymeric format for the first time. Use of EP in therapeutic treatment requires proper dose and route of administration. Proper follow-up of neurological disorders and timely diagnosis of them has been found to depend on EP level. The MIP sensor was developed by electrodeposition of starch NP-RGO composite on EQCM electrode in presence of template EP. As the imprinted sites are located on the surface, high specific surface area enables good accessibility and high binding affinity to template molecule. Differential pulse voltammetry (DPV) and piezoelectrogravimmetry were used for monitoring binding/release, rebinding of template to imprinted cavities. MIP-coated EQCM electrode were characterized by contact angle measurements, AFM images, piezoelectric responses including viscoelasticity of imprinted films, and other voltammetric measurements including direct (DPV) and indirect (using a redox probe) measurements. Selectivity was assessed by imprinting factor (IF) as high as 3.26 (DPV) and 3.88 (EQCM). Sensor was rigorously checked for selectivity in presence of other structurally close analogues, real matrix (blood plasma), reproducibility, repeatability, etc. Under optimized conditions, the EQCM-MIP sensor showed linear dynamic ranges (1–10[Formula: see text][Formula: see text]M). The limit of detection 40 ppb (DPV) and 290 ppb (EQCM) was achieved without any cross reactivity and matrix effect indicating high sensitivity and selectivity for EP. Hence, an eco-friendly MIP-sensor with high sensitivity and good selectivity was fabricated which could be applied in “real” matrices in a facile manner.

Petroleum products being transported through pipelines can be easily targeted by economic and political saboteurs. Unmanned Aerial Vehicle (UAV) heralds a new technology on pipeline safety, surveillance, surveying mapping, assessment and safety for the oil and gas industry. With the advent of this technology, leaks, corrosion, third party interference and other faults leading to the loss of life, environmental pollution can be checked. This review highlights the state of the technology and benefits of UAV to the Nigeria oil and gas industry. The Nigeria oil and gas industry vested with over 2,300,000 barrels of crude oil daily production has over 9000km pipeline route which is prone to rupture from leaks, corrosion and vandalism. The industry will benefit from a flexible compatible and adaptable UAV platform with a multispectral and hyper spectral sensor for extensive safety, real-time imagery within a localized small to medium spatial scale, over larger expanse of space and time. The technology is adjured cheaper for inspection mission over traditional methods. Adoption of these technology would improve the environmental imprints of the oil and gas companies operating in the Niger Delta, and cases of pipeline vandalism and unrest might be lessened.

Recently published studies have shown that microfluidic devices fabricated by in-house three-dimensional (3D) printing, computer numerical control (CNC) milling and laser engraving have a good quality of performance. The 3-in-1 3D printers, desktop machines that integrate the three primary functions in a single user-friendly set-up are now available for computer-controlled adaptable surface processing, for less than USD 1000. Here, we demonstrate that 3-in-1 3D printer-based micromachining is an effective strategy for creating microfluidic devices and an easier and more economical alternative to, for instance, conventional photolithography. Our aim was to produce plastic microfluidic chips with engraved microchannel structures or micro-structured plastic molds for casting polydimethylsiloxane (PDMS) chips with microchannel imprints. The reproducability and accuracy of fabrication of microfluidic chips with straight, crossed line and Y-shaped microchannel designs were assessed and their microfluidic performance checked by liquid stream tests. All three fabrication methods of the 3-in-1 3D printer produced functional microchannel devices with adequate solution flow. Accordingly, 3-in-1 3D printers are recommended as cheap, accessible and user-friendly tools that can be operated with minimal training and little starting knowledge to successfully fabricate basic microfluidic devices that are suitable for educational work or rapid prototyping.

This chapter proposes another scaled-down receiving wire for Radio Frequency Identification uses of 2.45 GHz. Our design comprises of a roundabout microstrip fix radio wire which integrates two concentric annular openings imprinted on multi-facet substrates. The transmission capacity, one of the main qualities of radio wire, can be essentially improved by utilizing a multi-facet dielectric setup. We point by this review to show that the impact of emanating structure stacked by annular rings for the fixed size decrease as well as the benefit of this construction is to make a roundabout polarization toward maximal radiation design. The wave idea iterative method is utilized to examine this new radio wire. Utilizing the proposed technique, less figuring time and memory are expected to work out the electromagnetic boundaries of our plan. The approval of the consequences of our created model was checked with realized business programming called “CST Microwave Studio Software” trailed by a trial test. As per the arrived results, we can decide that our new plan radio wire is reasonable for RFID applications in the 2.45 GHz band.
