Published: May 2022

Magnetized water has been a promising approach to improve crop productivity but the conditions for its effectiveness remain contradictory and inconclusive. The objective of this research was to understand the influences of different magnetized water with varying quality on seed absorption, germination, and early growth of cotton. To this end, a series of experiments involving the seed soaking process, germination test, and pot experiment were carried out to study the effects of different qualities (fresh and brackish water) of magnetized water on seed water absorption, germination, seedling growth, photosynthetic characteristics, and biomass of cotton in 2018. The results showed that the maximum relative water absorption of magnetized fresh and magnetized brackish water relatively increased by 16.76% and 19.75%, respectively, and the magnetic effect time of brackish water was longer than fresh water. The relative promotion effect of magnetized brackish water on cotton seed germination and growth potential was greater than magnetized fresh water. The cotton seeds germination rate under magnetized fresh and magnetized brackish water irrigation relatively increased by 13.14% and 41.86%, respectively, and the relative promoting effect of magnetized brackish water on the vitality indexes and the morphological indexes of cotton seedlings was greater than magnetized fresh water. Unlike non-magnetized water, the net photosynthetic rate (Pn), transpiration rate (Tr), and instantaneous water use efficiency (iWUE) of cotton irrigated with magnetized water increased significantly, while the stomatal limit value (Ls) decreased. The influences of photosynthesis and water use efficiency of cotton under magnetized brackish water were greater than magnetized fresh water. Magnetized fresh water had no significant effect on biomass proportional distribution of cotton but magnetized brackish water irrigation markedly improved the root-to-stem ratio of cotton within a 35.72% range. Therefore, the magnetization of brackish water does improve the growth characteristics of cotton seedlings, and the biological effect of magnetized brackish water is more significant than that of fresh water. It is suggested that magnetized brackish water can be used to irrigate cotton seedlings when freshwater resources are insufficient.

Published: May 2022

The practice of odorant analysis can often be very challenging because odorants are usually composed of a host of volatile organic compounds (VOCs) at low concentrations. Preconcentration with solid phase microextraction (SPME) is a conventional technique for the enrichment of these volatile compounds before analysis by headspace gas chromatography-mass spectrometry (GC-MS). However, commercially available SPME products usually bear the defects of weak mechanical strength and high cost. In this work, novel SPME fibers were prepared by a one-pot synthesis procedure from divinylbenzene (DVB), porous carbon powder (Carbon) and polydimethylsiloxane (PDMS). Factors that influence the extraction efficiency, such as extraction temperature, extraction time, salting effects, pH, stirring rate, desorption temperature and time, were optimized. VOCs in landfills pose a great threat to human health and the environment. The new SPME fibers were successfully applied in the analysis of VOCs from the leachate of a cyanobacteria landfill. Quantification methods of major odor contributors were established, and a good linearity (r > 0.998) was obtained, with detection limits in the range of 0.30–0.50 ng/L. Compared to commercial SPME fibers, the new material has higher extraction efficacy and higher precision. Hence, it is suitable for the determination of hazardous odorants of various sources.

Published: May 2022

Chemical accidents are the biggest factor that hinders the development of the chemical industry. Issuing an emergency evacuation order is one of effective ways to reduce human casualties that may occur due to chemical accidents. The present study proposes a machine learning-based decision making model for faster and more accurate decision making for the issuance of an emergency evacuation order in the event of a chemical accident. To implement the decision making model, supervised learning by the 1-Dimension Convolutional Neural Network based model was carried out using the HSEES and NTSIP data of ATSDR in the United States. An action—victim matrix was devised to determine the validity of emergency evacuation orders and the decision making model was made to learn the matrix so that the decision making model could recommend whether to execute the emergency evacuation orders or not. To make the decision making model learn the chemical accident situations, the embedding technique used in text mining was applied, and weighted learning was carried out considering the fact that learning data are asymmetric. The AUROC value for the results of the decision making by the model is 0.82, which is at a reliable level. Establishing such an emergency response decision making model using the method proposed in the present study in the mitigation stage will help the process. Among the chemical accident emergency management stages, constructing a database for the model, and using the model as a tool for quick decision making for an emergency evacuation order, is also thought to be helpful in the establishment and implementation of emergency response plans for chemical accidents.

Published: May 2022

In order to improve the pump device efficiency of the frequent operating condition of the extra-low head pumping station, the energy performance of the front-positioned shaft tubular pump device at two guide vane inlet angles has been researched. Based on the function of the guide vane in the pump device, the guide vane blades are divided into three parts: the inlet section, the middle section, and the outlet section. Combining numerical simulation and model tests, the energy performance of the pump device with the inlet section angle adjusted to 0° and −12° were studied and compared, respectively. The research results indicate that the inlet section angle of the guide vane has a significant effect on the energy performance of the pump device. When the guide vane inlet section is adjusted clockwise, the pump device efficiency of the optimal operating point—while the efficiency of the pump device at a low head and large discharge that deviate from the optimal operating point—will be improved. The farther the working condition deviates from the optimal operating point, the greater the influence. Within the scope of the working conditions studied in this paper, the pump device efficiency of the optimal operating point is reduced by about 2%, and the pump device efficiency in the low head and high flow conditions is increased by 5% at the maximum. Adjusting the inlet section angle of the guide vane, the flow pattern in the guide vane will be improved, and the hydraulic loss of the guide vane will be decreased, thus the pump device efficiency is increased. The numerical calculation results of the energy performance agree with the model test results; the maximum error of the pump device efficiency is less than 7%. Adjusting the angle of the inlet section of the guide vane has great significance to the hydraulic design and engineering application of the extra-low head pump device.

Predicting feed intake in suckling lambs consuming both milk and pasture can be challenging, and thus intake values are often derived from solely milk or solid feed consumption. The present study investigated if dry matter (DM), organic matter (OM), and metabolisable energy (ME) intakes of lambs given a combination of milk and pellets under controlled conditions could be predicted with enough precision using dietary and faecal chemical composition. A total of 34 pre-weaned lambs bottle-fed milk replacer with or without access to pellets and kept in metabolic cages for four days were used. To develop the prediction equations, 54 faecal samples with detailed information on their chemical compositions, and the feed consumed by the lambs, were used. Pellet DMI was predicted from neutral detergent fibre concentration in faeces and pellets, pellets %DM, and live weight (LW) of lambs. Milk DMI was predicted from faecal Nitrogen concentration and LW. Milk and pellet DMI and their ME content were combined to predict DMI/d and ME intake/d. The equations developed were validated against 40 spot faecal samples randomly selected from the lambs. DM, OM, and ME intakes were predicted with high accuracy and precision. The results showed that the developed equations can be used with enough accuracy to predict ME, OM, and DM intakes in pre-weaned lambs ingesting milk and pellets concurrently, thus the results revealed that the established equations may be used to predict ME, OM, and DM intakes in pre-weaned lambs drinking milk and pellets at the same time, allowing feeding regimens for young lambs to be developed.

Published: May 2022

Car crashes are among the top ten leading causes of death; they could mainly be attributed to distracted drivers. An advanced driver-assistance technique (ADAT) is a procedure that can notify the driver about a dangerous scenario, reduce traffic crashes, and improve road safety. The main contribution of this work involved utilizing the driver’s attention to build an efficient ADAT. To obtain this “attention value”, the gaze tracking method is proposed. The gaze direction of the driver is critical toward understanding/discerning fatal distractions, pertaining to when it is obligatory to notify the driver about the risks on the road. A real-time gaze tracking system is proposed in this paper for the development of an ADAT that obtains and communicates the gaze information of the driver. The developed ADAT system detects various head poses of the driver and estimates eye gaze directions, which play important roles in assisting the driver and avoiding any unwanted circumstances. The first (and more significant) task in this research work involved the development of a benchmark image dataset consisting of head poses and horizontal and vertical direction gazes of the driver’s eyes. To detect the driver’s face accurately and efficiently, the You Only Look Once (YOLO-V4) face detector was used by modifying it with the Inception-v3 CNN model for robust feature learning and improved face detection. Finally, transfer learning in the InceptionResNet-v2 CNN model was performed, where the CNN was used as a classification model for head pose detection and eye gaze angle estimation; a regression layer to the InceptionResNet-v2 CNN was added instead of SoftMax and the classification output layer. The proposed model detects and estimates head pose directions and eye directions with higher accuracy. The average accuracy achieved by the head pose detection system was 91%; the model achieved a RMSE of 2.68 for vertical and 3.61 for horizontal eye gaze estimations.
Compliant Mechanism-Based Sensor for Large Strain Measurements Employing Fiber Optics
Authors: Shiryayev Oleg , Vahdati Nader , Yap Fook Fah , Butt Haider
Published: May 2022

We propose a sensor design for measurement of large strains where direct application of a fiber optic strain gauge is impossible due to the stiffness mismatch between the optical fiber and the structure under test. The sensor design is based on a rhombus type compliant mechanism, which functions to attenuate input strain and transfer it to the ends of the sensing beam with the mounted optical strain gauge. We developed an analytical model of the sensor, which allows us to relate actuation forces, input displacement/strain, and output strain. The analytical model was verified with the finite element analysis and validated against an experimental prototype. The prototype sensor was able to handle input strains exceeding ±2.5 × 105 µε. Potential application areas of the proposed sensor include compliant elastomeric structures, wearables, and soft robotics.
Adolescence and Postpartum: Two Life Periods to Deepen Our Understanding of the Complexity of Female Rat Sexual Behavior
Authors: Agrati Daniella
Published: May 2022

The sexual behavior of the female rat has been extensively studied and used as a model for human female sexuality. The development of models that focus on sexual interaction from the female’s perspective has demonstrated the complexity of this behavior, in which motivational and affective aspects have great relevance. This review describes, from a historical perspective, some of the studies that have shed light on this complexity and presents the potential of two periods in the female’s life to expand our understanding of sexual behavior: adolescence and postpartum estrus. Cycling adolescent female rats can express sexual behavior even though some of the underlying circuitry is still developing. Therefore, this is an ideal time for studying the ontogeny of sexual behavior, the interaction of sexual and social motivations, and the neuroendocrine changes that lead to adult behavior. Female rats also show a fertile estrus a few hours after parturition. During this period, rats are simultaneously sexually and maternally motivated, making postpartum estrus an excellent model for exploring the interaction of these two social motivations. What we know so far about female sexual behavior in these unique periods of life reaffirms its richness and shows that much remains to be known.
Cultural Identity in Bicultural Young Adults in Ireland: A Social Representation Theory Approach
Authors: Ogoro Mamobo , Minescu Anca , Moriarty Mairead
Published: May 2022

This research investigates the nature by which first- and second-generation Irish young adults of (1) African descent, (2) Asian descent, and (3) Eastern European descent explore their cultural identity(ies) through communicating and interpreting social representations relating to their ethnic and national cultures. Using Social Representation Theory (SRT) and, more widely, Proculturation Theory as the theoretical underpinning, we examine how grown children of migrants construct their cultural identity(ies) by exploring external social representations. We conducted three separate in-depth focus groups for each continental group in virtual rooms on Zoom, lasting between 60 and 90 mins. A thematic analysis was pursued to understand how the participants discussed the representation of their cultural groups both in social and media-driven situations. The results indicated the overarching themes of Anchoring Irishness and Latent Media Representation, whereby participants communicated and dialogically explored their subjective interpretations of the social representations of their cultural groups which, in turn, may have informed their cultural identity(ies). Highlighting the dynamic nature of the cultural reality of Ireland and how it impacts generations after the initial migration period, this research highlights and exemplifies the importance of external social representations that serve to construct the multiple cultural identities of first- and second-generation migrants.

Relationship between the Superior Attachment of the Uncinate Process and Pneumatization of the Middle Turbinate—A Radiological Study
Authors: Calvo-Henriquez Christian , Mayo-Yañez Miguel , Chiesa-Estomba Carlos M. , Martinez-Capoccioni Gabriel , Martin-Martin Carlos
Published: May 2022

Objective: the superior attachment of the uncinate process (SAUP) is highly variable. Lateral types of SAUP are associated with frontal rhinosinusitis. SAUP in the middle turbinate is more common when the middle turbinate is aerated. We aim to refine these findings by studying the relationship between the SAUP type and the different subtypes of pneumatization of the middle turbinate. Methods: 200 CT sinonasal scans were analyzed by an otolaryngologist and a radiologist. All CT scans were analyzed to study the type of the middle turbinate concha bullosa and lamellar cell and the type of SAUP. Results: 379 sides were analyzed. The prevalence of the various types of SAUP were: Type I: 43.80%, Type II: 22.16%, Type III: 16.36%, Type IV: 3.69%, Type V: 9.76%, and Type VI: 4.22%. When studying the pneumatization of the middle turbinate and the SAUP types, we only found a statistically significant association between the lateral attachment of the uncinate process and the presence of a lamellar cell (p = 0.029). Conclusion: lateral types of SAUP are more likely in the presence of a lamellar cell. This finding, therefore, renders checking for lateral SAUP types in the presence of a lamellar cell even more relevant than when studying the pre-surgical CT scan. In those cases, it is advisable to perform a careful and complete uncinectomy.

Published: May 2022

Current strategies for the evaluation of patients with chest pain have significantly changed thanks to the implemented potentiality of CT and MRI. The possible fatal consequences and high malpractice costs of missed acute coronary syndromes lead to unnecessary hospital admissions every year. CT provides consistent diagnostic support, mainly in suspected coronary disease in patients with a low or intermediate pre-test risk. Moreover, it can gain information in the case of cardiac involvement in pulmonary vascular obstructive disease. MRI, on the other hand, has a leading role in the condition of myocardial damage irrespective of the underlying inflammatory or stress related etiology. This article discusses how radiology techniques (CT and MRI) can impact the diagnostic workflow of the most common cardiac and vascular pathologies that are responsible for non-traumatic chest pain admissions to the Emergency Department.

Authors: Rebelo Sandra , Patuleia Mafalda , Dias Álvaro
Published: May 2022

Full accessibility to people with reduced mobility, applied to tourism, is difficult to achieve and should not be seen in an absolute way, but as a concern to make tourism services more accessible and focused on the specific and individual needs of people as tourists. National and regional entities should adopt good practices to build a tourism of all, for all. The Delphi method was used in order to verify the accessibility and attractiveness of the city of Lisbon as a tourist destination by addressing the following objectives: to analyse the competitiveness of a destination for people with reduced mobility, to analyse if Lisbon is attractive and inclusive, considering its infrastructures, services, hospitality, tourist attractions and accessibility. The results obtained in the study show that Lisbon’s factors and resources are increasingly accessible to people with reduced mobility. Our findings reveal that entertainment, general and tourism infrastructures, accommodation, the various activities and cultural resources and the quality of services present greater accessibility for people with reduced mobility. The factors with less importance were: marketing of a destination, accessibilities, and natural resources.

Anticholinesterase pesticides are a main cause of the intentional or accidental poisoning of animals. Anticholinesterases include several substances that cause the overstimulation of both central and peripheral acetylcholine-dependent neurotransmission. Forensic analyses of poisoning cases require high levels of expertise, are costly, and often do not provide reliable quantitative information for unambiguous conclusions. The purpose of the present study was to develop and validate a method of high-performance liquid chromatography with diode array detector (HPLC–DAD) for the identification and quantitation of n-methyl carbamates, organophosphates and respective metabolites from biological samples of animals that were suspected of poisoning. HPLC–DAD is reliable, fast, simplistic and cost-effective. The method was validated for biological samples obtained from stomach contents, liver, vitreous humor and blood from four different animal species. The validation of the method was achieved using the following analytical parameters: linearity, precision, accuracy, selectivity, recovery, and matrix effect. The method showed linearity at the range of 25–500 μg/mL, and the correlation coefficient (r2) values were >0.99 for all matrices. Precision and accuracy were determined by the (a) coefficient of variation (CV), (b) relative standard deviation low-quality control (LQC), (c) medium-quality control (QCM), and (d) high-quality control (QCA). The indicated parameters were all less than 15%. The recovery of analytes ranged from 31 to 71%. The analysis of results showed no significant interfering peaks due to common xenobiotics or matrix effects. The abovementioned method was used to positively identify pesticide analytes in 44 of the 51 animal samples that were suspected of poisoning, demonstrating its usefulness as a forensic tool.
Nanoplastics: Status and Knowledge Gaps in the Finalization of Environmental Risk Assessments
Authors: Masseroni Andrea , Rizzi Cristiana , Urani Chiara , Villa Sara
Published: May 2022

Nanoplastics (NPs) are particles ranging in size between 1 and 1000 nm, and they are a form of environmental contaminant of great ecotoxicological concern. Although NPs are widespread across ecosystems, they have only recently garnered growing attention from both the scientific community and regulatory bodies. The present study reviews scientific literature related to the exposure and effects of NPs and identifies research gaps that impede the finalization of related environmental risk assessments (ERAs). Approximately 80 articles published between 2012 and 2021 were considered. Very few studies (eight articles) focused on the presence of NPs in biotic matrices, whereas the majority of the studies (62 articles) assessed the lethal and sublethal effects of NPs on aquatic and terrestrial organisms. Whilst many studies focused on nude NPs, only a few considered their association with different aggregates. Amongst NPs, the effects of polystyrene are the most extensively reported to date. Moreover, the effects of NPs on aquatic organisms are better characterized than those on terrestrial organisms. NP concentrations detected in water were close to or even higher than the sublethal levels for organisms. An ERA framework specifically tailored to NPs is proposed.

Pharmaceuticals are widely acknowledged to be a threat to aquatic life. Over the last two decades, the steady use of biologically active chemicals for human health has been mirrored by a rise in the leaking of these chemicals into natural environments. The aim of this work was to detect the toxicity of sodium fluoride (NaF) exposure and platinum-derived drugs in an ecological setting on aquatic organism development. From 24 to 96 h post-fertilization, zebrafish embryos were treated to dosages of NaF 10 mg/L−1 + cisplatin (CDDP) 100 μM, one with NaF 10 mg/L−1 + carboplatin (CARP) 25 μM, one with NaF 10 mg/L−1 + CDDP 100 μM + CARP 25 μM. Fluoride exposure in combination with Cisplatin and Carboplatin (non-toxic concentration) had an effect on survival and hatching rate according to this study. Additionally, it significantly disturbed the antioxidant defense system and increased ROS in zebrafish larvae. NaF 10 mg/L−1 associated with CDDP 100 μM and CARP 25 μM, increased the production of apoptosis-related proteins (caspase 3, bax, and bcl-2) and the downregulation of acetylcholinesterase (AChE) activity, while no effect was seen for the single exposure.

Authors: Herrera Luis , Di Prisco Alicia , Ospino Justo
Published: May 2022

We carry on a general study on non-static spherically symmetric fluids admitting a conformal Killing vector (CKV). Several families of exact analytical solutions are found for different choices of the CKV in both the dissipative and the adiabatic regime. To specify the solutions, besides the fulfillment of the junction conditions on the boundary of the fluid distribution, different conditions are imposed, such as a vanishing complexity factor and quasi-homologous evolution. A detailed analysis of the obtained solutions and its prospective applications to astrophysical scenarios, as well as alternative approaches to obtain new solutions, are discussed.

Published: May 2022

Development of urban housing requires participation of various stakeholders, from the state, private sector, and community to the civil society organizations. Cognizant of that fact, this research sought to establish the measurement model for stakeholders’ participation in an urban housing development from the neo-liberal perspective. The study employed a quantitative approach, in which a structured questionnaire containing 25 indicator variables identified from literature was administered to a total of 214 respondents drawn from key institutions involved in housing development and planning in Lusaka, Zambia. Data collected were analyzed through exploratory factor analysis (EFA) as well as confirmatory factor analysis (CFA), with goodness-of-fit based on a two-index strategy used in determining model acceptability. Results revealed that stakeholders’ participation is defined by seven variables, namely: private sector participation in the provision of affordable housing finance; private sector participation through construction of rent-to-buy housing; private sector participation through partnering in the provision of basic services; community participation in the develop of housing programs; the state facilitating access to affordable housing finance; the state stimulating private sector involvement in affordable housing provision; non-governmental organizations participation by coordinating the communities. The study outlines roles of various actors in housing development from a developing country’s perspective.

Analysis of longitudinal dynamics of humoral immune responses to the BNT162b2 COVID-19 vaccine might provide useful information to predict the effectiveness of BNT162b2 in preventing SARS-CoV-2 infection. Herein, we measure anti-RBD IgG at 1, 3 and 6 months (M) after the second dose of BNT162b2, and at 1 M after a third dose of BNT162b2 vaccination in 431 COVID-19-naïve healthcare workers (HCWs) in Japan. All HCWs mounted high-anti-RBD IgG responses after the two-dose regimen of BNT162b2 vaccinations. Older persons and males presented lower anti-RBD IgG responses than younger adults and females, respectively. The decay in anti-RBD IgG started from 1 M after the second dose of BNT162b2 and anti-RBD IgG titers dropped to nearly one-tenth at 6 M after the second vaccination. Subsequently, the participants received a third dose of BNT162b2 at 8 M after the second dose of BNT162b2 vaccine. Anti-RBD antibody titers 1 M after the third dose of BNT162b2 increased seventeen times that of 6 M after the second dose, and was twice higher than the peak antibody titers at 1 M after the second dose of vaccination. The negative effect of age for the male gender on anti-RBD IgG antibody titers was not observed at 1 M after the third dose of BNT162b2 vaccine. There were no notable adverse events reported, which required hospitalization in these participants. These results suggest that the third dose of BNT162b2 safely improves humoral immunity against SARS-CoV-2 with no major adverse events.

Published: May 2022

Objective: India and Europe have large populations, a large number of Coronavirus disease 2019 (COVID-19) cases, and different healthcare systems. This study aims to investigate the differences between the hesitancy toward and preference for COVID-19 vaccines in India and four European countries, namely, the United Kingdom (UK), Germany, Italy, and Spain. Methodology: We conducted a cross-national survey for distribution in India, the UK, Germany, Italy, and Spain. More specifically, a discrete choice experiment (DCE) was conducted to evaluate vaccine preferences, and Likert scales were used to probe the underlying factors that contribute to vaccination acceptance. Propensity score matching (PSM) was performed to directly compare India and European countries. Results: A total of 2565 respondents (835 from India and 1730 from the specified countries in Europe) participated in the survey. After PSM, more than 82.5% of respondents from India positively accepted the COVID-19 vaccination, whereas 79.9% of respondents from Europe had a positive attitude; however, the proportion in Europe changed to 81.6% in cases in which the vaccine was recommended by friends, family, or employers. The DCE found that the COVID-19 vaccine efficacy was the most important factor for respondents in India and the four European nations (41.8% in India and 47.77% in Europe), followed by the vaccine cost (28.06% in India and 25.88% in Europe). Conclusion: Although most respondents in both regions showed high acceptance of COVID-19 vaccines, either due to general acceptance or acceptance as a result of social cues, the vaccination coverage rate shows apparent distinctions. Due to the differences in COVID-19 situations, public health systems, cultural backgrounds, and vaccine availability, the strategies for COVID-19 vaccine promotion should be nation-dependent.

Education in Serbia in the context of globalization: geopolitical, regional and anthropological dimensions
Authors:   Faculty of International Relations and Tourism, Moscow University for the Humanities, Filimonova Anna Igorevna
Published: May 2022

The processes of globalization are inseparable from the reduction of national sovereignty and state powers, Westernization and universalization of culture and standardization of the educational sphere. One of the main phenomena in the educational sphere in the era of globalization has been the system of dual education, borrowed from Germany, where it arose on the basis of specific historical conditions, and extended to other countries, however, with a key change in the goals and results of this project, in particular for the country in question — Serbia. Here, the dual system is designed to bring the educational sphere in line with globalization processes, in fact, to subordinate the national and state interest in this elfkbnmimportant area to the geopolitical and private commercial strategy. The dual system is focused on the main “pillar of globalization”: the labor market, and, as a result, it removes the ethical and organizational restrictions of the educational process, which is asymmetrically, to the detriment of the fundamental theoretical part, is reduced in favor of practical production. The reduction and relativization of general education programs lead to the formation of a new anthropological type of student and graduate of the dual system, in which the postmodern consciousness, skills and “competences” necessary for the globalization cult of the deregulated market are cultivated. However, the deficit of cognitive competencies, along with the build-up of technical skills, leads, on the one hand, to an increase, and not a decrease, in the exploitation by foreign enterprises in the country itself, and on the other hand, ironically, to an outflow of technically qualified personnel to the country that is the source of the dual education model — Germany, as well as to other industrially and technologically advanced countries of the world.

The article is devoted to one of the key events in ancient Russian history at the beginning of the 13th century. On July 20, 1217, on the commemoration day of the holy prophet Elias, the Ryazan princes Gleb and Konstantin Vladimirovich killed six of their closest relatives right during the princely congress in the Isady village. Despite the fact that conspiracies and murders were not uncommon in the Rurik dynasty, this monstrous massacre far surpassed in its scale all previous similar crimes in the history of pre-Mongol Russia. The author considers this event, as well as its assessment in the Russian historical literature.

The article provides a theoretical substantiation of the essence and content of inter-organizational relations in order to ensure inter-organizational cooperation of agricultural formations as an effective tool for maintaining the competitiveness of the domestic agricultural sector. The dynamic development of economic relations influenced the use of innovative technologies, caused the objective need for the introduction of new software solutions in the organization of the agro-industrial complex, including in relation to the system of economic security of inter-organizational cooperation. In order to promptly obtain the necessary data, form and present information in management accounting to optimize the inter-organizational relations of agribusiness organizations and make important management decisions, a mechanism is required that allows for the support of such decisions in a short time. Such a mechanism is an inter-organizational management accounting system in combination with a balanced scorecard, reporting, control system and other systems that ensure inter-organizational interaction. The purpose of the study is to substantiate the theoretical foundations of the formation and presentation of information in the framework of management accounting in order to develop inter-organizational relations of agricultural organizations.. Special attention is paid to the issues related to the elements of inter-organizational relations, the content of such relations.

CICE pre-Financing and Employment Effects : an ex post Evaluation.

The ex post evaluation presented here endeavours to measure the potential effects of the CICE pre-financing mechanism on preserving jobs due to fewer company failures in 2013 and 2014. The econometric analysis is backed by exhaustive data from INSEE and the use of propensity score matching methods (Kernel, five nearest neighbours, and Caliper). The results indicate that the pre-financed firms could have destroyed around 2,500 jobs (the effects range from approximately 900 to 4,000), if all else being equal, they had not received pre-financing. This effect only applies to firms with between 10 and 100 employees and only for 2013. Thus, the results of this study do not showa significant effect for very small firms (between 2 and 9 employees) or for firmswith more than 100 employees. The positive effect of pre-financing on safeguarding jobs in 2013 can be regarded as the upper end of the job preservation range, as a failed company may be forced out of the market.

The reaction of epoxyphosphazenes with methacrylic acid was used to synthesize methacrylate-containing phosphazene oligomers (MPO) used to modify dental restorative materials.

The introduction of 1015 wt.% MPO into the base bis-methacrylate binder composition can significantly increase the adhesion of modified cured compositions to tooth tissues and metals, as well as improve water resistance while maintaining the required strength indicators and other physicochemical characteristics required by GOST.

The aryloxyphosphazenes containing carboxylic groups in phosphorus-linked radicals and capable of copolymerization with acrylic binders were used as modifiers of dental polymer compositions. Filled modified dental compositions have been obtained and tested. It has been shown that the best mechanical and physicochemical parameters are exhibited by cured compositions with a modifier based on aryloxyphosphazene with 4-hydroxycinnamic and eugenol radicals in the phosphazene ring.

El ejemplar tipo de Dactylozodes bruchi Kerremans (= Lasionota (Lasionota) bruchi (Kerremans)) (Coleoptera: Buprestidae) fue localizado y reconocido como holotipo por monotipia. Sus sinonimias, Dactylozodes rubidipennis y D. rubidipennis ab. suturinotata (nombre infrasubespecífico no disponible), fueron estudiadas a través de las descripciones originales y de fotografías de parte del material tipo, confirmando que son conespecíficas con L. (L.) bruchi. Adicionalmente, en base a un único ejemplar hembra recolectado en la localidad de Zapala (provincia del Neuquén, Argentina), se describe e ilustra una nueva especie de Lasionota del centro-oeste de Argentina. El ejemplar a partir del cual se describe el nuevo taxón fue identificado preliminarmente como L. (L.) bruchi, especie con la cual cohabita. Sin embargo, se concluyó que el espécimen corresponde a una nueva especie después del estudio de material tipo y no tipo de L. (L.) bruchi y sus sinonimias.

Omorgus (Omorgus) suberosus (Fabricius, 1775) es una especie de Trogidae cuyos hábitos alimenticios les permite asociarse a cualquier fuente de queratina, incluidas las heces de diversas especies omnívoras; sin embargo, no se ha reportado en excretas de mamíferos carnívoros. El objetivo de este trabajo es informar, por primera vez, la atracción de O. suberosus a excretas de dos especies de mamíferos carnívoros en condiciones de cautividad en remanentes de selva subperennifolia de la región central de Chiapas, México. Se realizaron muestreos sistemáticos mensuales durante un año, utilizando trampas de caída cebadas con excretas de seis especies de mamíferos (herbívoros, carnívoros y omnívoros) nativos de la región, con el fin de verificar su efectividad para la atracción de escarabajos. Se capturaron 18 individuos de O. suberosus durante cuatro meses del ciclo de muestreo. A pesar de utilizar una amplia variedad de excretas para el muestreo de escarabajos, los individuos fueron atraídos únicamente a heces de las dos especies de mamíferos carnívoros: Canis latrans Say, 1823 y Panthera onca (Linnaeus, 1758). Se reafirma su tolerancia hacia los ambientes antropizados y la captura de los ejemplares sugieren una marcada presencia estacional.
