Published: March 2021

A logo is a special symbol or symbol that represents a company or organization. A logo can be a name, symbol or other graphic element that is displayed visually [1]. All institutions have a logo, especially an educational institution, namely the University, but the university logo is rarely remembered by lecturers, students, or the public. To be able to remind and provide information about the university, the university logo scan application which will later be directed to the university link is considered by the author suitable to be made. This kind of research has been tested with high accuracy but does not use the University logo. This research will utilize Augmented Reality program design with slight modifications and apply the Template Matching method that will be made with the Unity Game Engine and Vuforia SDK. This research was successful as evidenced by the smooth installation of APK and good program performance. In addition, this study obtained 84% accuracy in the detection of markers (logos) which were known by the distance and focus of the camera. This research also gets 100% accuracy in the direction to the intended university link.

Soft corals are the second-largest group of biotas that consist of coral reef ecosystem other than hard corals. The ecology function of soft coral such as a place to live and shelter various types of fish, soft coral also has a high economic value as an export commodity for the ornamental aquarium and the potency in pharmacology. The great economy potency can urge to uncontrolled natural taken. One of the alternatives is by culturing with transplantation method. Environment and different growth responses among soft coral species are the factors that shows the success method research used. The aims of this research were to examine the average growth rates of different transplanted soft coral species, culturing location, and the presence of interaction between different species of transplanted soft coral and culturing location towards growth rates. The average survival rates of different species of transplanted soft corals that cultured in a different location. Culturing location was located inside and outside of Pegametan bay, Buleleng regency. There were three soft coral species Lobophytum strictum, Sinularia polydactyla and S. asterolobata with five replicates each. The soft corals were fragmented with initial size ± 25 cm2 then sewed to the cement substrate. It was placed randomly to the transplant table at different culturing locations. The increased size of each transplanted soft coral species, the number of survivals and environmental parameters were observed in every two weeks for 12 weeks. Results showed that the average growth rates of soft corals significantly differed among species (P<0.05), whereas the average growth rates of transplanted L. strictum were the lowest among others. In contrast, the average growth rates of transplanted S. polydactyla, and S. asterolobata were not significantly different (P = 0.100) at all locations. The average growth rates of all transplanted soft corals were significantly lower when cultured inside the bay (P<0.05). It is found that the different average growth rates of transplanted soft corals were due to the interaction between soft coral species and location. The results also demonstrated that the average survival rates were significantly varied among transplanted soft coral species (P<0.05). All transplanted soft corals cultured outside of the bay reached 100% survival rates. It is suggested that the morphology and anatomy of each soft coral species and environmental conditions contribute to the success of soft corals transplantation.

Published: March 2021

Microalgae Chaetoceros gracilis is widely used in aquaculture. Its culture highly depends on environmental factors, particularly temperature. This study aimed to examine the growth rate and its growth trend of C. gracilis, also chlorophyll-a concentration at different temperature. cultures were incubated at 25, 30 dan 340C for seven days using Na media with three replicates. Cell density was counted every day using a hemocytometer, whereas the concentration of chlorophyll-a was measured in spectrophotometry method. The differences in growth rates and chlorophyll-a concentration at different temperatures were statistically analyzed with One-Way ANOVA. The difference variables were further tested with the Tukey HSD test. The trend of the growth and duration of C. gracilis at 25 and 30 0C were similar, with the lag phase (three days), logarithmic (two days), stationary (one day), and declination (one day), in contrast at 34 0C that had lower duration and missed the stationary phase. The growth rates of microalgae C. gracilis was insignificantly differences at the temperature of 25 and 30 0C (0.7±0.05 cell/ml/day), but significantly lower at 340C (0.28±0.03 cell/ml/day). The chlorophyll-a concentrations at the temperature of 25 and 30 0C were not significantly different (0.37±0.05 and 0.39±0.03 mg/l), while the chlorophyll-a concentration at 34 0C was significantly lower (0.26±0.04 mg/l). This result indicates the high temperature (34 0C) inhibited the metabolism of C. gracilis as shown by doubling times that slower (2.5 day) than the temperature at 25 and 30 0C. It is concluded that the optimum temperatures for the C. gracilis were 25 and 30 0C, where as 340C was the inhibited temperature.

Authors:   Kazan (Volga Region), Federal University, Vorobeva Elena E. ,   Institute of Archaeology named after A.Kh. Khalikov, Tatarstan Academy of Sciences
Published: March 2021

The settlements of the Iron Age in the territory of the Volga Region have always been particularly interesting in terms of historical science. This is justified not only by the uniqueness of this territory, but also by the formation of a substantial collection of archaeological materials. A significant number of archaeological sites of the early Iron Age have been discovered and investigated over more than half a century of archaeological research and scientific studies in the territory of the Mari Volga region. This paper introduces the main types of settlements widely spread across the territory of the Mari Volga region during the Early Iron Age. The authors discuss the causes for such innovations as the appearance of settlements in the territory of the Mari Volga region. They provide characteristics of the settlement fortifications of the Mari Volga region population of the early Iron Age. The paper addresses the issues of space organization of both fortified and unfortified settlements of the Mari Volga Region in the early Iron Age. The authors suggest that the causes for the appearance of fortified settlements are associated with both internal and external factors. This in turn influenced the construction innovations of the settlements belonging to the population of the Mari Volga region.

Published: March 2021

The last decade has seen important technological and methodological advances in the field of palaeogenomics, constantly pushing back the time boundary and broadening our understanding of past human-animal interactions. As well as the development of sequencing technologies, a variety of organic material is being (re)evaluated as potential substrates for DNA analyses. The authors here review a selection of these, including collagenous (leather and parchment), keratinous (hair and feather) and calcified (shell and eggshell) material, and environmental DNA including coprolite. The authors focus on the biological structure of these materials in relation to DNA preservation, highlighting their singularity in comparison to bones and teeth, and inform on some of their direct applications. Finally, the authors consider some of the new perspectives these substrates can bring to our understanding of the past, notably surrounding manufacturing practices and health.

The paper for the first time publishes and analyzes the materials obtained in the study of the burial of the child no. 10 in the barrow 16 of the “Sluiceway” group near the Glinoe village, Slobodzeya district, on the left bank of the Lower Dniester. The grave dates back to the third quarter of the 4th century BC and contained the burial of a small child. The western part of the pit was intended to sacrificial food and a knife, and the eastern part was intended for the body of the child and grave goods, where a “bed” was made of a mixture of natural clay and humus. Two Cypraea moneta shells, one glass bead, as well as an iron model of the sword were part of the necklace. The last find is a unique item in the Scythian burials of the North Black Sea region. It imitated swords of the Solokha type (with claw-shaped tops and false-triangular crosshairs), known in the Scythian burials of the Northern Black Sea Region from the last quarter of the 5th century BC until the end of the 4th century BC. It is noteworthy that it was such a sword that was found in the pair burial of the same barrow where the burial of the child was sunk. There is no doubt that the model of the sword in the necklace of a child was a votive object. Perhaps it indicated the child's belonging to the estate of the warriors.

The publication presents materials of the funeral necropolis Kyrykungir (East Kazakhstan), in which two sets of astragals with traces of coloring pigments were discovered. The design of the burials accompanying the inventory and the general archaeological context allows dating these objects from the 12th to 13th centuries BC. Data from archaeozoological analysis and SEM-EDX analysis of the painted surface of objects (alchiks) are present in the paper. The species composition of animals has been established, demonstrating a combination of astragals of both domestic and wild species. A diverse chemical composition of paints with which objects were covered, as well as cases of renewal of staining, was revealed. In the initial version, individual astragals could belong to population with different traditions of making paints, possibly from different regions. The results allow us to offer a different point of view on the phenomenon of the presence of alchiks in archaeological cultures. The range of interpretations of astragals (alchiks) finds implies not only understanding them as elements of game traditions, but also designating their complex social and cultural role in the funeral rites of the population of Eurasia in the Bronze Age.

Published: March 2021

This paper reports on an Aboriginal site complex, incorporating hut structures, ceremonial stone arrangements, an extensive surface artefact assemblage of lithics and mussel shell, and a silcrete quarry, located along Hilary Creek, a tributary of the Georgina River in western Queensland, Australia. At least two phases of occupation are indicated. The most recent huts have their collapsed organic superstructure still present, while those of a presumably earlier phase are distinguished as bare, circular patches of earth which are conspicuous amongst the ubiquitous gibber, with or without stone bases, and lacking any collapsed superstructure. Immediately adjacent to the huts and also a few hundred metres away are clusters of small stone arrangements, and about 2 km to the southwest, along the same creekline, is another series of larger, more substantial stone arrangements; these features speak to the importance of the general Hilary Creek area for ceremonial purposes. Radiocarbon dating reveals use of the Hilary Creek complex dates to at least 300 years ago; the absence of any European materials suggests it was likely not used, or only used very sporadically, after the 1870s when pastoralists arrived in the area, and when traditional lifeways were devastated by colonial violence.

Authors: Julitasari Evi Nurifah , Sulistiarini Emma Budi , Payon Yovita Serat
Published: March 2021

Pandemi Covid-19, berdampak pada perekonomian khususnya juga terhadap petani cabe. Harga cabe yang turun drastis menyebabkan petani menderita kerugian, hal ini disebabkan cabe segar tidak terserap seluruhnya oleh industri makanan, restoran maupun konsumsi masyarakat.  Penurunan harga ini harus diimbangi dengan pengolahan menjadi produk lain yang mempunyai nilai tambah tinggi, misalnya pengolahan cabe kering, abon cabe dan lain sebagainya. Namun sayangnya kemampuan petani untuk mengolah menjadi cabe olahan masih terbatas, oleh karena itu tim kami mengadakan pelatihan dan pendampingan dalam pengolahan cabe segar menjadi cabe kering. Kelompok sasaran kami adalah petani yang tergabung dalam kelompok tani Manggisari, yang terletak di desa Bocek Kecamatan Karangploso Kabupaten Malang, sebagai salah satu sentra penghasil cabe di Kabupaten Malang. Pelatihan yang didukung oleh LPPM Universitas Widyagama Malang dengan melibatkan mahasiswa program studi Agrobisnis, diharapkan dapat memberi inspirasi, untuk mengolah cabe hasil panennya menjadi cabe kering. Sebelumnya dilakukan penyuluhan dengan memberi pemahaman bahwa harga cabe olahan lebih tinggi dari pada dijual segar atau akan memberi nilai tambah kurang lebih Rp. 10.000/kg. Harapannya dengan memberi hasil perhitungan petani akan mempercayainya (seeing is believing). Program ini akan dilanjutkan secara terus menurus dan khususnya  pada kelompok tani wanita (KWT) untuk secara berkelompok melakukan pelatihan pembuatan cabe kering.

Objetivo: Correlacionar a rotina de hidratação e o nível de conhecimento dos estagiários de odontologia de uma instituição de ensino privado de Rondônia com as suas consequências. Métodos: Pesquisa quantitativa realizada no segundo semestre de 2020 em uma instituição de ensino privado de Porto Velho/Rondônia. Os dados foram levantados por meio da aplicação de um questionário envolvendo 50 estagiários do curso de Odontologia, matriculados entre o sexto e oitavo período. Resultados: Constatou-se que em relação à ingestão de água, 50% dos estagiários alegaram beber entre 1 litro e 1,5 litro do líquido por dia, abaixo da recomendação da OMS que indica, no mínimo, dois litros de reposição hidroeletrolítica, e quando questionados sobre os motivos do esquecimento da hidratação, os participantes alegaram, majoritariamente, que a carga de trabalho seguida por momentos de pausa reduzidos, são a principal causa. Conclusão: Apesar de grande parte dos entrevistados conhecerem a importância da hidratação, a maioria não a realiza de forma adequada. Nesse sentido, o problema não está na falta de conscientização, mas sim na falta de conhecimento sobre as consequências da desidratação e o dano que isso pode ocasionar.

İşsizlik, tüm ekonomilerin önemle üzerinde durması gereken makroekonomik sorunlardan biridir. Üretim maliyetlerindeki artış ve teknolojik gelişmeler yeni iş kollarının doğmasına sebep olurken, birçok işkolunun da makineleşmeyle birlikte şekil değiştirdiği görülmektedir. Bu çalışmada Türkiye’de işsizlik histerisi, hem toplamda hem de kadın ve erkek işsizliği bağlamında ayrı ayrı incelenecektir. İşsizlik histerisi kavramı, herhangi bir şok durumunda işsizlik serilerinin ortalamaya dönme eğilimi göstermemesi biçiminde açıklanabilir. Eğer, seri birim köke sahip değilse yani durağan bir özellik sergiliyorsa, histeri etkisi taşımadığı ve herhangi bir şok durumunda şokun etkisinin geçici olduğu belirtilecektir. Eğer, serinin birim köke sahip olduğu yani durağan olmadığı belirlenirse, bir şok sonrasında seri ortalamaya dönmeyecek ve şokun etkisi uzun sürecektir. Bu çalışmada, işsizlik histerisi doğrusal olmayan serilerde yapısal değişimlerin de etkisini modele katan Güriş (2019) tarafından literatüre kazandırılan Fourier Kruse birim kök testiyle incelenecektir. Bu amaçla, 1988-2018 dönemi yıllık verileri kullanılarak işsizlik histerisinin geçerli olup olmadığı araştırılmıştır. Çalışmada kadın işsizliğinde histeri etkisinin olduğu belirlenmiştir. Erkek işsizliği ve toplam işsizlikte, yığılımlı modelde histeri etkisinin olmadığı saptanmıştır. Bu sonuçlara göre, meydana gelen şoklardan kadın işsizliğinin daha fazla etkilendiği; erkek işsizliğinin ise şoktan önceki durumlarına kolayca geri döndüğü bilgisi elde edilmiştir.
The Environmental and Economic Viability of Chitosan Production in Guayas-Ecuador: A Robust Investment and Life Cycle Analysis
Authors: Riofrio Ariel , Alcivar Tania , Baykara Haci
Published: March 2021

Ecuador is a country where shrimp production is one of its primary industries. It generates annually about 72 thousand tons of wastes in the form of shrimp shells. Therefore, using this waste as a raw material resource to produce chitosan, a biopolymer, is established. An environmental and economic performance study is carried out as a possible investment report; where a conceptual design of the process is defined, a financial viability report is obtained. An environmental impact report establishes the degree of harm to the environment. The economic viability study considered costs related to capital and operation for the processing of 5000 tons of shrimp shells each year. On the other hand, a life cycle assessment was performed to obtain the environmental impact for 1 kg of chitosan produce, where a cradle-to-gate approach was established. Results showed that this new industry has a net present value of 10.38 million USD, a rate of return of 67.31%, and a payback period of 0.7 years. Additionally, it was calculated that the environmental impact with a higher normalized value was the human non-carcinogenic toxicity. It is concluded that the production of chitosan in Guayas-Ecuador is economically viable, cost-competitive in the market, and it represents an industrial activity with no considerable environmental impacts.
Toward Sustainable Li-Ion Batteries Recycling: Green MOF as a Molecular Sieve for the Selective Separation of Cobalt and Nickel

Published: March 2021

The growing demand for Li-ions batteries (LIBs) has made their postconsumer recycling an imperative need towards the recovery of valuable metals, such as cobalt and nickel. Nevertheless, their recovery and separation from active cathode materials in LIBs, via an efficient and environmentally friendly process, have remained a challenge. In this work, we approach a simple and green method for the selective separation of nickel ions from mixed cobalt-nickel aqueous solutions under mild conditions. We discovered that the bioinspired microporous metal–organic framework (MOF), Bi2O(H2O)2(C14H2O8)∙nH2O is a selective sorbent towards Ni(II) ions at pH 5-7, but does not adsorb Co(II) ions. According to the Freundlich isotherm, the adsorption capacity towards Ni(II) reached 100.9 mg∙g−1, while a near-zero adsorption capacity was found for Co(II) ions. Ni(II) removal from aqueous solutions was performed at mild conditions (22 °C and pH 5), with a high yield up to 96%. Presence on Ni(II) ions adsorbed on the surface of the material has been proven by solid state 1H nuclear magnetic resonance (NMR) spectroscopy. Finally, separation of Ni(II) from Co(II) from binary solutions was obtained with approximately 30% yield for Ni(II), with a near-zero adsorption of Co(II), which has been demonstrated by UV-Vis spectroscopy. These results offer a green pathway toward the recycling and separation of valuable metals from cobalt-containing LIBs, while providing a sustainable route for waste valorization in a circular economy.
Img2Mol - Accurate SMILES Recognition from Molecular Graphical Depictions
Authors: Clevert Djork-Arné , Le Tuan , Winter Robin , Montanari Floriane
Published: March 2021

Automatic recognition of the molecular content of a molecule’s graphical depiction is an extremely challenging problem that remains largely unsolved despite decades of research. Recent advances in neural machine translation enable the auto-encoding of molecular structures in a continuous vector space of fixed size (latent representation) with low reconstruction errors. In this paper, we present a fast and accurate model combining a deep convolutional neural network learning from molecule depictions and a pre-trained decoder that translates the latent representation into the SMILES representation of the molecules. This combination allows to precisely infer a molecular structure from an image. Our rigorous evaluation show that Img2Mol is able to correctly translate up to 88% of the molecular depictions into their SMILES representation. A pretrained version of Img2Mol is made publicly available on GitHub for non-commercial users.
1st Row Transition Metal Aluminylene Complexes: Preparation, Properties and Bonding Analysis
Authors: Kong Richard Y , Crimmin Mark
Published: March 2021

The synthesis and spectroscopic characterisation of eight new first-row transition metal (M = Cr, Mn, Fe, Co, Cu) aluminylene complexes is reported. DFT and ab initio calculations have been used to provide detailed insight into the metal–metal bond. The σ-donation and π-backdonation properties of the aluminylene ligand are evaluated via NBO and ETS-NOCV calculations. These calculations reveal that these ligands are strong σ-donors but also competent π-acceptors. These properties are not fixed but vary in response to the nature of the transition metal centre, suggesting that aluminylene fragments can modulate their bonding to accommodate both electron-rich and electron-poor transition metals. Ab initio DLPNO-CCSD(T) calculations show that dispersion plays an important role in stabilising these complexes. Both short-range and long-range dispersion interactions are identified. These results will likely inform the design of next-generation catalysts based on aluminium metalloligands.

Published: March 2021

Each year, millions of premature deaths worldwide are caused by exposure to outdoor air pollution, especially fine particulate matter (PM2.5). Designing policies to reduce deaths relies on air quality modeling for estimating changes in PM2.5 concentrations from many policy scenarios at high spatial resolution. However, air quality modeling typically has high requirements for computation and expertise, which limits policy design, especially in countries where most PM2.5-related deaths occur. Lower requirement reduced-complexity models exist but are generally unavailable worldwide. Here, we adapt InMAP, a reduced-complexity model originally developed for the United States, to simulate annual-average primary and secondary PM2.5 concentrations across a global-through-urban spatial domain: “Global InMAP”. Global InMAP uses a variable resolution grid, with 4 km horizontal grid cell widths in cities. We evaluate Global InMAP performance both against measurements and a state-of-the-science chemical transport model, GEOS-Chem. For the emission scenarios considered, Global InMAP reproduced GEOS-Chem pollutant concentrations with a normalized mean bias of 59%–121%. Global InMAP can be run on a desktop computer; simulations here took 2.6–4.4 hours. This work presents a global, open-source, reduced-complexity air quality model to facilitate air pollution policy assessment worldwide, providing a tool for reducing the deaths where they occur most.

In this work, we demonstrate a novel method for multi-domain analysis of properties of analytes in volumes as small as picoliter, combining electrochemistry and optical measurements. A microcavity in-line Mach-Zehnder interferometer (µIMZI) obtained in a standard single-mode optical fiber using femtosecond laser micromachining was able to accommodate a microelectrode and optically monitor electrochemical processes inside the fiber. The interferometer shows exceptional sensitivity to changes in optical properties of analytes in the microcavity. We show that the optical readout follows the electrochemical reactions. Here, the redox probe (ferrocenedimethanol) undergoing reactions of oxidation and reduction changes the optical properties of the analyte (refractive index and absorbance) that are monitored by the µIMZI. Measurements have been supported by numerical analysis of both optical and electrochemical phenomena. On top of a capability of the approach to perform analysis in microscale, the difference between oxidized and reduced forms in the near-infrared can be clearly measured using the µIMZI, which is hardly possible using other optical techniques. The proposed multi-domain concept is a promising approach for highly reliable and ultrasensitive chemo- and biosensing.

The poor health literacy choice is associated with poor health, riskier behavior, more hospitalization and lack of self-management. Developing literacy and providing health information to reduce inequality of health in adults in the southern part of India. To study a case pattern of adults concerning the conditions of health information and to assess the impact in the condition of health literacy score with understanding a short educational presentation. The current study was carried out at one of the Multi speciality Hospital, Nellore, Andhra Pradesh from January 2017 to March 2017. Assessment tool of health literacy validated and utilized in this study with the inspection of health information questionnaire elicited both data on the participants and demographic data related to health information. Association of inspection between patterns and variables of the sample population used related health information. Potential sources regarding health information, general practitioner rank was highest, and their first preference would be 70%. Their second and third preference 50% ranking followed by the clinical pharmacist. All 100 % of participants' health information themselves sought ongoing medical conditions and also seeking about themselves to 85% new medical conditions. The mean newest vital sign baseline scores for the sample of 4.4 (Std. deviation = 2.912) with inline the health literacy survey results for India which means 2.526 for all ages and 2.643 over 56 years. The study confirmed that considerable methods of the cohort study of older Indian people have substantial problems with health literacy and also warrants additional attention.

The iron-21 syrup is used for iron deficiency anaemia which supplies iron and calories a provide iron and calorie nutriment to recompense haemoglobin deprivation. The objective of this study is to determine acute oral toxicity of Iron-21 syrup in vivo in Wistar rats. Iron-21 Syrup formulation was given through the oral route. The syrup formulation was administered in three increasing doses of 3, 6 and 12 ml/kg body weight for concentration of 500, 1000 and 2000mg/kg respectively. The other group of rats designated as a control group was given the only vehicle orally. The test and control group contains five rats each. Tests, as well as control group rats, were sacrificed on the fifteenth day of treatment. The blood and tissue samples of test animals were sent for histopathological studies examination. Four parameters were observed throughout the study, and they are cage side observation, the effect to the body weight, haematological parameter and histopathology. All animals were survived till they sacrificed. No notable changes were found in behaviour, haematological and histopathology studies. The oral administration of Iron-21 Syrup is not shown any toxic effect in the animal at a given dose. Therefore, it is a safe remedy for human use.

Methotrexate is one of the most popular and safe anti-inflammatory drugs which is an antifolate-type antimetabolite and is used as an anticancer drug. In this study, oppositely charged chitosan and fucoidan have been non-covalently bonded using their electrostatic interactions with the methotrexate drug loaded into these nanoparticles. Fucoidan is obtained from marine algae which are composed of l-fucose and sulfate groups in various types of brown seaweeds; whereas chitosan is a naturally occurring biopolymer obtained through the N-deacetylation of chitin. Depending on the fucoidan / chitosan (F / C) weight ratio, three distinct nanoparticles (1F / 1C; 3F / 1C; 5F / 1C) are synthesized and characterized. Nanoparticles were prepared using cross linkers EDC and NHS at a constant pH to reduce the conjugate size. The prepared conjugates were characterized for their size and zeta potential using DLS analysis and the functional groups were analysed using FTIR. DLS results proclaimed that there was size reduction in particle size with cross linker and without the drug methotrexate. The 5:1 F/C nanoparticles was seen to be 441.5 nm, the difference being considerable larger in the 5:1 formulation. Hence for further analysis 5:1 F/C nanoparticles were preferred. Maximum entrapment efficiency was observed in 5:1 F/C nanoparticle with and without cross linkers. To understand the structural morphology of nanoparticles electromagnetic magnification like SEM and TEM were taken in account.

The problem of the lack of a uniform approach to classifying criminal manifestations as a group of crimes and offenses in the consumer market is revealed. The high relevance of this issue is noted, due to the interest in it from law enforcement and Supervisory authorities. Based on the current legislation, criminal law and economic doctrine, the discussion issues related to the concept of the consumer market are considered, and its significance in the formation of the concept of crimes in the consumer market is established. It is established that crimes on the consumer market, being potentially dangerous, from the point of view of the possibility of causing harm to the life and health of citizens, damage to property owners, harm to the health of the population as a whole, require preventive measures by law enforcement agencies aimed at preventing the occurrence of further negative consequences. It is concluded that the presence of a victim is not a mandatory criterion for classifying an act as committed on the consumer market. An algorithm has been developed that allows accounting entities to apply a unified approach to classifying relevant acts.

The transformation of public danger of environmentally hazardous acts is considered. It has been established that in the process of historical development, the approach to determining their harmfulness has changed: previously it was associated with the violation of ownership rights to natural resources, and now it is associated with the possibility of complete destruction or change of nature. It is stated that the nature of the public danger of environmental crimes has greatly changed. The main actions that have a negative impact on the natural environment have been identified. It has been established that the degree of social danger of these acts has greatly increased. It is noted that the transformation of the public danger of the analyzed acts occurred in a very short period of time, and the current criminal law does not take into account the changes in full. Special measures are proposed to improve the criminal law protection of the environment and natural resources: taking into account the selfish motive when committing them, the formation of elements of environmental crimes as compounds of real danger
