Study of textile carpet combustion process

Currently, synthetic carpet products are widely used in the home, as they compare favorably with natural ones in terms of technical characteristics. This is due to their high durability, lack of tendency to rot, wide range of colors and relatively low cost of production. However, the ease, ignition and increased flammability of most synthetic carpet products result in rapid spread of fire through them, igniting other products and objects in the vicinity. The sources of the fire are usually matches, cigarettes, careless handling of fire, and short circuits. In this regard, the purpose of the study is to investigate the combustion process of textile synthetic carpet products of "Bal Textile" LLP with justification of the most rational methods of flammability and combustibility assessment. Subject of research: processes of thermo-oxidative destruction of modified polypropylene textile materials and their relationship with fire hazard properties, flammability of fiber-forming polymers. The combustion process of synthetic carpet products of Bal Textile LLP with different Heat Set yarn densities and pile lengths were investigated. Based on the research we have done, it has been concluded that the higher the pile of the carpet, the higher the level of combustion. Carpets melt when ignited and are also colored as a black liquid. The value of the conducted research is that on their basis it is possible to classify materials by degree of combustibility (flammability) and to develop requirements for synthetic carpet products of LLP "Bal Textile" of reduced fire hazard taking into account their possible application in practice.

Paclitaxel - a Product of Fungal Secondary Metabolism or an Artefact?

Taxol (common name: paclitaxel) is an extremely important component of drugs for the treatment of various cancers. Thirty years after the discovery of its effectiveness, a metabolic precursor of Taxol (10-deacetylbaccatin III) is still primarily extracted from needles of European yew trees. In order to meet the considerable demand, hopes were pinned on the possibilities of biotechnological production from the very beginning. In 1993, as if by chance, Taxol was supposedly discovered in fungi that grow endobiotically in yew trees. This finding aroused hopes of biotechnological use to produce fungal Taxol in large quantities in fermenters. It never came to that. Instead, a confusing flood of publications emerged that claimed to have detected Taxol in more and more eukaryotic and even prokaryotic species. However, researchers never reproduced these rather puzzling results, and they could certainly not be applied on an industrial scale. This paper will show that some of the misguided approaches were apparently based on a seemingly careless handling of sparse evidence and on at least questionable publications. Apparently, the desired gold rush of commercial exploitation was seductive. Scientific skepticism as an indispensable core of good scientific practice was often neglected, and the peer review process has not exerted its corrective effect. Self-critical reflection and more healthy skepticism could help to reduce the risk of such aberrations in drug development. This article uses this case study as a striking example to show what can be learned from the Taxol case in terms of research ethics and the avoidance of questionable research practices.

The causes of fires at industrial facilities of the Russian Federation in general and in individual industries were studied on the basis of statistical information. It has been shown that most often – in 36 % of cases – the cause of a fire is a violation of the rules for the design and operation of electrical equipment. In 22 % of cases, a fire occurs due to careless handling of fire, in 11 % of cases – due to violation of the rules for the design and operation of vehicles. The distributions of the frequency of fire occurrence for various reasons for enterprises in different industries are given. An analysis of the most common causes of fire in general for industrial enterprises and for individual industries was carried out. Measures are proposed that will minimize the likelihood of fires and explosions in industrial enterprises.

Enforcement of data breaches in the Dutch and British healthcare sector: a contribution to clarifying requirements of data protection by design?

ABSTRACT Within the healthcare sector, highly sensitive personal data, including data concerning health, is processed. The careless handling of such data can have a significant impact on the fundamental rights and freedoms of natural persons. It is central that data protection principles, including data protection by design, are followed by the healthcare sector. When these requirements are not met, it is crucial that enforcement action is taken to prevent personal data breaches. This article compares the enforcement carried out in the Netherlands and in the UK for breaches in the healthcare sector of the General Data Protection Regulation and the UK Data Protection Act 2018. The author reflects on whether more effective enforcement measures would lead to healthcare developments that are compliant with the data protection by design obligation (Article 25 of the GDPR). It is argued that in turn,compliance with this obligation can prevent personal data breaches and data protection complaints, rendering enforcement, and consequently recovery, superfluous.

Assessments of some animal bones biochar as paddy protectants against rice weevil, Sitophilus oryzae L. [Coleoptera: Curculionidae]

The main insect pest of stored paddy is Sitophilus oryzae (rice weevil). Huge amounts of rice are produced by peasant farmers each year, but the bulk of it is wasted due to insufficient storage facilities and insect pest attacks brought on by careless handling. In this study, the insecticidal effects of biochar on S. oryzae were assessed in femurs from Sus scrofa (pig), Gallus gallus (chicken), and Bos taurus (cattle). Adult mortality, adult emergence, weight loss, seed damage, and weevil perforation index are among the indicators evaluated. To apply the biochar, different dosages were used: 0.2, 0.4, 0.6, 0.8, and 1.0 g/20 g of paddy rice. In this work, the population of adult S. oryzae on paddy rice was dramatically reduced by all animal bones biochar tested for insecticidal activity (p < 0.05). The animal bone biochar became more effective with increasing dosage. After 24 h of treatment, pig biochar induced a 36.67 % mortality rate of adult S. oryzae, followed by cow biochar's 20 % mortality rate of rice weevils. The fatal dose of cattle, pig, and chicken biochar at which 50 % (LD50) of the population of adult S. oryzae responded after 24 h of treatment were 0.83g, 0.43g, and 0.90g, respectively. It should be encouraged to utilize biochar made from animal bones to combat the S. oryzae in stored paddy. They could be utilized as a green control measure to lessen the risk brought on by the usage of synthetic chemical insecticides in the environment.

No Body, No Crime? Vicariously Imagining Africa’s Arsenic Century: Bovines, Arsenic Poisoning and Multi-Species Toxic Histories in Southern Rhodesia (Colonial Zimbabwe), 1900–1940s

During the first half of the twentieth century, white settler farmers in colonial Zimbabwe raised incessant complaints and alarm over ‘mysterious’ and inexplicably frequent incidences of cattle mortalities. These mortalities were attributed to poisoning from careless handling of arsenical dips, ingestion of arsenic sprayed grass and grazing in veld impregnated with arsenic trioxide. The arsenic question occupied the attention of experts from the colonial Branch of Chemistry, toxicologists, bacteriologists, veterinary officials and white settler farmers in contested cattle-centred narratives. Within the framing of colonial toxic politics, cattle poisoning disproportionately received more elaborate scrutiny and attention than that of humans and other species. The colonial archive only affords limited and vague visibility to the toxic encounters of humans and non-bovine species. This paper seeks to transcend and interrogate bovine-centric poisoning discourses with which colonial sources are replete and to use existing cattle poisoning records to amplify and construct multi-species toxic histories connecting cattle, humans, landscapes and other species in a co-constituted narrative of arsenic toxicities. The paper employs vicarious imagination of experiences to reframe Africa’s ‘arsenic century’ and colonial toxic histories outside the body-centric script, and examines the intricate and complex chemical relations enmeshing cattle, humans and other species in ecosystems of mutual toxic vulnerabilities and slow chemical violence. The paper uses archival sources, toxicological reports from the Branch of Chemistry and veterinary records of cattle poisoning in colonial Zimbabwe.

Protection of Digital Archives in the Archives of Bosnia and Herzegovina

One of the basic tasks of every archives, in addition to collecting and making archival records available, is to protect them from damage and loss. Records, regardless of whether they are „traditional“ or digital, are subject to deterioration. Daily careless handling and improper storage conditions contribute to increasing the risk of their permanent disappearance. The author will discuss current experiences of the Archives of Bosnia and Herzegovina in manipulating digital records, especially in the aspect of preservation and protection, taking into account sharp contrast between historical importance of the fonds that are stored and the outdated and technically insufficient IT equipment which is currently in use.

Numerical parametric analysis of the decomposition and propagation of combustion products in a confined environment in the early stages of a fire

Numerical research findings are presented on the patterns of spread of thermal decomposition products of wood-based materials in confined spaces isolated from the external environment. Based on the experimental data, a physical problem statement was formulated and a mathematical model of heat and mass transfer was developed for rooms with the most typical sources of fire hazard. The experimental and numerical research findings were obtained for the conditions corresponding to compartments isolated from the external environment (e.g., rooms at dedicated facilities, like ships, small and medium-sized rooms) and to underventilated rooms. The performed experiments and calculations revealed satisfactory agreement in the findings and demonstrated the validity of the proposed model of heat and mass transfer. Wood was used as the main material in fires. A comparative analysis was also carried out for paper of different quality. The modeling was performed for the most frequent causes of fires: careless handling of fire, unsafe operation of heating equipment and electrical short circuits. The rates of growth of thermal decomposition product concentrations were determined for different distances from the material. The impact of a number of factors on the characteristics under study was determined. These are the fire and room sizes, fire cause, supply and exhaust ventilation. The data were extrapolated to the conditions corresponding to business, warehouse and residential premises.

Remediation of hydrocarbons and metals by hydrocarbon utilizing Pseudomonas taiwanensis YSA-17 isolated from soil contaminated with petroleum.

Careless handling of petroleum in petrochemical industries releases toxic hydrocarbons and metals to soil and water. The aim of the present study was to isolate hydrocarbon-utilizing and metal-tolerant bacteria. Hydrocarbon-utilizing bacteria from petroleum-contaminated soils were isolated on the Bushnell Hass medium. Hydrocarbon degradation by Pseudomonas taiwanensis strain YSA-17 was observed by gas chromatography-mass spectrometry. Bioaccumulation of metals by strain YSA-17 was assessed in nutrient broth. Among different strains, YSA-17 showed the highest potential for hydrocarbon utilization. After 20 days of incubation, YSA-17 completely degraded one compound and during its degradation, there was the formation of 13 new compounds which were absent in uninoculated control. Results of scanning electron microscope and Fourier transmission infrared (FTIR) indicated degradation of hydrocarbons. FTIR showed the formation of new functional groups in YSA-17 inoculated medium. Expression of the total quantity of hydrocarbon-degrading gene (AlkB and NehAc) in petroleum-amended nutrient broth inoculated with strain YSA-17 enhanced significantly during 20 days of incubation compared to control. YSA-17 also significantly removed metals. This study concluded that bioinoculant can be utilized for the bioremediation of pollutants cocontaminated with hydrocarbons and metals. Petroleum-contaminated soil will be remediated for pollutants.

О лесных пожарах в лесах Челябинской области за 2018–2021 годы и анализ требований к воспроизводству лесов в лесохозяйственном регламенте

The article presents the results of a four-year study of the number of forest fires on the territory of 22 forestries in the Chelyabinsk region. It was revealed that the main cause of fires is the human factor such as careless handling of fire. The number and intensity of fires are somewhat dependent on the number of crown fires and weather conditions. Forest fires cause enormous economic and environmental damage to the environment. The damage from a forest fire consists of the loss of standing wood and the cost of extinguishing work, clearing and restoring burned areas, losses from the death of animals, moreover, the calculations have shown that the economic damage from fires can significantly exceed the cost of extinguishing them. Environmental damage from fires consists of the loss of natural resources, for example, valuable animals or rare plants, listed in the Red Book of the Chelyabinsk region of Russia, may be lost due to a forest fire. In order to carry out the most effective reforestation and afforestation, each of the 22 forest areas has developed forest management regulations for reforestation in accordance with the Order of the Ministry of Natural Resources and Ecology of the Russian Federation No. № 188 by 25.03.2019 making changes to it. The article presents an analysis of the forestry regulations on the example of the Krasnoarmeyskoye forestry of the Chelyabinsk region.

Pesticide use and Their Impacts on Health of Farmers: A Study in Rajapur Area, Bardiya (Nepal)

A study was conducted in the Rajapur municipality and Geruwa Rural municipality to determine the types of pesticides used in agriculture and their potential effects on farmers' health. Interviews were conducted with 240 farmers from 12 villages in the study area, and the information provided suo moto by the farmers were analyzed. This study found that the farmers frequently use pesticides in the extremely risky to highly deadly categories, such as carbamates, pyrethroids, organophosphides, and organophosphates. It has been discovered that the majority of farmers in the study area are ignorant of the dangers to human health presented by the mentioned pesticides and the consequences of their careless handling. Farmers cover their faces with cloth fabric masks and smoke tobacco to protect them. In addition, it was noticed that after spraying the pesticides, other typical farming activities continued in the agricultural fields. So, there is also a possibility that these pesticides will directly come into touch with women, children, and other field employees. There were numerous illnesses and physiological abnormalities with various indications and symptoms. A significant relative risk (RR) was also noted. It was discovered that the farmers of the study area have poor state of health which was aggravated by the lack of awareness and failure to implement suitable preventive measures regarding use of pesticides.

AMMUNITION, EXPLOSIVES AND EXPLOSIVE DEVICES AS OBJECTS OF CRIMINAL ATTACKS IN THE COMMISSION OF A CRIMINAL OFFENSE UNDER ARTICLE 263-1 OF THE CRIMINAL CODE OF UKRAINE

One of the subjects of criminal encroachment in the commission of a crime under Art. 263-1 of the Criminal Code of Ukraine are ammunition, explosives and explosive devices. Such objects are capable of causing destruction, have the ability to cause bodily injury or death to a person and form significant material harm. At the present stage, in the absence of a basic law on weapons, in practice, there are certain problems with the qualification of the acts of persons as the illegal manufacture of ammunition, explosives and explosive devices. The article presents the concepts and types of these elements of the forensic characteristics of a crime under Art. 263-1 of the Criminal Code of Ukraine. The classification of ammunition, explosives and explosive devices makes it possible to differentiate a specific object as the subject of a crime under Art. 263-1 of the Criminal Code of Ukraine, to determine its forensically significant properties and characteristics. Particular attention is paid to traces that appear at the site of careless handling of ammunition, explosives and explosive devices. To inspect the sites of these incidents, it is imperative to involve specialists in ballistics, explosives specialists, as well as other persons with special knowledge in the field of ballistics and explosives. The presence of these specialists also ensures the safety of other participants in this investigative action. Ammunition, explosives and explosive devices as objects of criminal assault have a close relationship with the personality of the offender, the method of committing a criminal offence and the pattern of traces. Therefore, the establishment of the objects of criminal encroachment and their study allow you to correctly select the methods, techniques and means of investigation, determine the optimal sequence of investigative actions, and also properly ensure the investigation of a crime under Art. 263-1 of the Criminal Code of Ukraine. The article concludes with the importance of ammunition, explosives, and explosive devices for establishing the elements of a forensic characterization of a crime under Art. 263-1 of the Criminal Code of Ukraine, and the need to use the special knowledge of experts involved in the relevant criminal proceedings.

CHANGING THE ENVIRONMENTAL PARADIGM THROUGH 3R (Reuse, Reduce, Recycle) EDUCATION: Student Devotion to Plastic Waste Management and Sustainable Creativity with Economical Value

The environment is home to all forms of life, especially humans, and protecting it is an absolute obligation. Environmental quality greatly affects human life. Even though there are many ways to protect the environment, careless waste handling is still a troubling problem. Piles of garbage on the streets and especially plastic waste, which is difficult to decompose, are increasingly widespread and have an increasingly serious impact. To respond to this, we as academic members feel the need to contribute in the form of Student Community Service, which we do at the Al Kamilah Foundation, Jl. Raya No. 3, Serua, Bojongsari District, Depok City, West Java. Our main goal is to increase awareness of the dangers of plastic waste and teach them how to process it into valuable and economically valuable goods. We apply the 3R (Reuse, Reduce, Recycle) training method with a focus on making piggy banks from plastic bottles. The results of this activity indicated the enthusiasm of the participants in learning and being creative with plastic waste. The resulting creations are not only useful as a place to store pocket money, but also have the potential to be used as business products. Through this activity, we hope to be able to provide valuable learning to the participants and open the door for ongoing training to improve their ability to manage plastic waste in an innovative and sustainable way.

An Example of the Use of Photogrammetry for Archiving the Shapes of Natural Materials and Creations

We can find cultural monuments everywhere. Smaller ones are often made from available and cheap natural materials - stones. However, due to the weather, due to their smaller dimensions, are often subject to vandalism, damage caused by careless handling or accidental damage. Sometimes they are just pieces of stone, but they have a deeper meaning in connection with cultural value, and for example by studying them in office spaces in the form of 3D models. In our contribution, we focus on the protection, study and preservation of such cultural and artistic monuments made of natural materials or generally stone natural formations or even large stone or brick surfaces. In our article, we want to focus on the practical feasibility rather than the mathematical background, as we believe that this information is much more useful in practice. We point out that it is advisable to use drones to check the condition of materials.

SYSTEM OF PHYSICAL PROTECTION DURING TRANSPORTATION OF SOURCES OF IONIZING RADIATION OF THE FIRST CATEGORY

The discovery of radioactivity by Antoine Henri Becquerel in 1896 was a major achievement. Today, radioactive substances are used in medicine, agriculture, heavy industry, and power generation. But while radioactivity has a wide range of useful applications, this discovery also has a flip side - the misuse of ionizing radiation that can lead to burns, radiation sickness, death, cancer, tumors and genetic mutations. A source of ionizing radiation (IRS) is a physical object containing radioactive material or a technical installation that generates or is capable of generating ionizing radiation under certain conditions. In order to ensure compliance with the permissible limits of radiation exposure of people, the population and the natural environment, as specified in codes, rules and safety standards, there is a national regulatory body. In Ukraine, since 2007, state registration of sources of ionizing radiation has been a part of licensing activities in the field of nuclear energy use. Those radioactive sources that are not or have never been under regulatory control, or are left unattended, lost, misplaced, diverted without proper government authorization, or stolen, are called "abandoned sources." The problem with "abandoned sources" is their potential danger to public health and the difficulty of detection. As a rule, sources of ionizing radiation are located in metal containers with thick walls, which makes it difficult to identify the presence of a radioactive source inside with the help of appropriate equipment. Furthermore, they are objects of different shapes and sizes, and as such they are often objects of interest to different groups of people with different purposes. Getting an "abandoned source" into the hands of ordinary citizens can have catastrophic consequences. An example of a similar situation is the radioactive contamination of the Brazilian city of Goiânia in 1987. After the theft, the perpetrators dumped radiation therapy equipment components containing the radioactive isotope cesium-137 into the trash. Later, this source was discovered by a local resident, whose actions and careless handling led to the spread of radioactive contamination, as a result of which four people died from radioactive contamination, and the area where this source is located is not suitable for life. the next 300 years.

“Truth,” “lies,” and beyond: epistemological prerequisites for a constructive political discourse

Building on methodical constructivism, the paper examines the differences between trans-subjectively founded (objective) reality, merely intersubjectively agreed (social) reality, and subjective reality in the narrow sense, and refutes the social constructivist view according to which every representation of reality only offers a distorted image of reality, so that all representations of reality stand side by side on an equal footing. Admitting that socially constructed reality is necessarily selective and therefore an interpreted (meaningful) reality, the paper argues that truth vs. falsehood is not the only criterion by which a construction of reality can be measured. Although the discourse about meanings cannot be a discourse about whether they are true or false, constructions of reality can nonetheless be questioned for their appropriateness for constructive problem solving. Political discourse, however, is all too often not about problem solving, but about gaining power, maintaining power, and using power in order to enforce one’s own positions. Appropriateness then gets replaced by mere expediency, and populist politicians drive this to a perfection in which their careless handling of truth is only the tip of the iceberg. At the base of the iceberg, there is the refusal of coexistence and the destruction of reasonable common ground, and the primary question that arises for social research is that of social pathologies that help populists’ (subjective) reality to become shared by (at least) parts of society.

Dynamics of Development of the Microvasculature and Tissue Structures of the Large Intestine in Case of Sequential Pesticide Poisoning

The ongoing worldwide intensive chemicalization of agriculture leads to the fact that annually a large number of various foreign chemicals (xenobiotics), including pesticides, enter the planet's biosphere, that is, the environment for the habitat of all living things, including humans. As a result of careless handling of pesticides, as well as accidental or intentional ingestion of the drug, acute and subacute poisoning occurn
