Die Berliner Polizei hat gegenüber Klimaaktivisten, die sich auf eine Straße gesetzt hatten, um diese zu blockieren, sogenannte Schmerzgriffe bzw. Nervendrucktechniken zunächst angedroht und sodann angewendet. Beide polizeilichen Maßnahmen, also Androhung und Anwendung, verstoßen gegen das Verhältnismäßigkeitsprinzip, weil das Wegtragen der Aktivisten ein milderes Mittel wäre. Je nach den Umständen des Einzelfalles kommt auch ein Verstoß gegen das Folterverbot in Betracht.
Implementation of the Principle of Common Heritage of Mankind According to the UN Convention on the Law of the Sea of 1982
Authors: Sitompul Mhd. Nasir
Published: July 2024

Common Heritage of Mankind is a principle in the International Law of the Sea system where the principle provides freedom of Natural Resources contained in the International Seabed or Seabed Area. The regulation of international law authorizes an international organization called the International Seabed Authority to carry out its role as supervision of the implementation of the principles of Common Heritage of Mankind in the International Seabed area. Article 136 of the International Convention on the Law of the Sea, Part XI of the Area states that “ the area and its resources are the common heritage of mankind”. In applying the principles of the Common Heritage of Mankind contained in Chapter XI UNCLOS 1982 was implemented under the Implementation Agreement 1994 which then established an international organization authorized to fully regulate and manage the resources that exist in the seabed and Deep Ocean where the common heritage of mankind on behalf of it acts.
Arbitration as an alternative means of dispute resolution to accommodate smart systems: "Artificial Intelligence as a Model"
Authors: Souad Mandar
Published: July 2024

Arbitration occupies an essential position as an alternative means of resolving disputes between individuals. It is a self-standing mechanism, under which the parties benefit from a set of advantages, such as the advantage of resolving their conflicts confidentially and within limited deadlines compared to the lengthy procedures of the ordinary judiciary. However, the emergence of advanced technology such as artificial intelligence techniques has begun to raise many questions about the possibility of benefiting from them in the future in alternative means of dispute resolution, such as arbitration, especially since the field of artificial intelligence is a highly developed field continuously, which raises a significant number of questions, all of which revolve around ways to benefit Arbitration of these types of advanced technology. Therefore, the study mainly aims to predict the future of arbitration in light of continuous technological development, especially with regard to artificial intelligence techniques. The subject was dealt with according to the coupling between the descriptive method, the analytical method, and the comparative method. The concept of artificial intelligence has also been clarified. Three hypotheses have been put forward that embody the extent of arbitration as an alternative means of dispute resolution to accommodate the artificial intelligence system in a first topic, with an evaluation of this system in arbitration and some applications that devote the tendency to resolve disputes amicably using artificial intelligence techniques in a second topic. The researchers concluded that the position of artificial intelligence in arbitration will inevitably appear clearly in the near future, so it should be dealt with special care so that only the strengths of artificial intelligence can be benefited from without compromising the basic values and principles of arbitration.

Management and accounts of the disentailment process in Seville Cathedral (19th century): the sale of estates
Authors: Caro Puro Rocío , Hernández Borreguero José Julián , Donoso Anes Alberto
Published: July 2024

Ecclesiastical disentailment has traditionally been associated with seizing real estate owned by "dead hands" for immediate sale. The administrative and accounting documentation of the Cathedral Chapter of Seville shows how it was forced to dispose of numerous properties in two phases during the 19th century. This was not carried out through confiscation but through orderly sales organised by the ecclesiastical institution itself, which is not mentioned in the historical-economic literature. This study analyses these alienations, their causes, procedures and consequences, as well as the financial problems the Cathedral Chapter of Seville faced, the application for numerous loans and the sale of real estate. The sales process, in our opinion, was serious, transparent and professional.

Tradicionalmente se ha asimilado desamortización eclesiástica con el proceso de incautación de bienes inmuebles en propiedad de las “manos muertas” para su inmediata venta. La documentación administrativa y contable del Cabildo Catedral de Sevilla muestra como en dos fases del siglo XIX se vio obligada a desprenderse de numerosos inmuebles, no mediante la confiscación, sino mediante un ordenado procedimiento de venta realizada por la propia institución eclesiástica, aspecto no mencionado por la literatura histórico-económica. El presente estudio analiza esas enajenaciones, sus causas, procedimiento y consecuencias. Se analizan los problemas financieros del Cabildo Catedral de Sevilla, la solicitud de numerosos créditos y la venta de inmuebles. El proceso de venta, en nuestra opinión, fue bastante serio, transparente y profesional.

SYNTHESIS OF SURFACTANTS FROM NATURAL RAW MATERIALS
Authors: Lutfullina Gulnaz G. , Valeeva Elvira E.
Published: July 2024

This article presents a surfactant synthesized from a mixture of palmitic, oleic, and stearic acids obtained by the distillation and fractionation of oils and fats, as well as ethanol. The synthesis was carried out in 4 stages, which involved the initial formation of an acid mixture, followed by esterification, sulfonation, and ultimately saponification. The composition of the fatty acid mixture was analyzed using chromatography, revealing that palmitic acid makes up the largest proportion at 64.3%, followed by oleic acid at 29.1%. The structure and properties of the surfactant were investigated using modern methods and instruments. The average particle size of the surfactant indicates that it can be classified as a highly dispersed system, with particle diameters ranging from 10 nm to 1 μm. It was observed that the particle size of the surfactant increases once the critical concentration of micellization is reached. The stability of the system in the substance is indicated by a ζ-potential that falls outside the range of 30 mV < ζ < -30 mV. The resulting product exhibits good surface-active properties such as detergency, emulsification, wetting, and foaming ability. According to hydrophilic-lipophilic balance calculations, the synthesized surfactant is classified as a detergent. It demonstrates a high ability to remove pigment-oil and protein contamination at a concentration of 4.0 g/dm3, regardless of the fabric type. Additionally, it was found that the synthesized surfactant exhibits significant emulsifying ability towards industrial oils. The analysis of the surface tension of the surfactant showed that its critical concentration for micelle formation is 4.0 g/dm3. The surfactant demonstrates high wetting abilities on both hydrophilic and hydrophobic surfaces. The foaming properties of the surfactant are satisfactory compared to known surfactants from petrochemical raw materials. Moreover, stable foaming is observed, which directly depends on the surfactant concentration.

CONSERVATION LAWS OF CHEMICAL REACTIONS IN A CLOSED NONISOTHRUM INCOMPLETE MIXING REACTOR
Authors: Kol'tsov Nikolay I.
Published: July 2024

In chemical reactions occurring stationary or non-stationary in closed isothermal ideal mixing reactors (CSTR), the classical linear stoichiometric laws of conservation are always satisfied, reflecting the constancy of atoms of one type or another during the entire reaction. In real conditions, taking into account possible deviations from ideal mixing conditions or violations of the constancy of temperature conditions, various macroscopic factors (mass transfer, heat transfer) can have a noticeable influence on the course of the reaction. To study the kinetics of such processes, a more general mathematical model of an incomplete mixing reactor (IMR) is used. It is of interest to study the influence of diffusion and convection on the patterns of stationary modes of non-isothermal chemical reactions associated with the existence of more general (non-stoichiometric) conservation laws (kinetic invariants). It is more difficult to detect such invariants (especially temperature ones) in IMRs than in CSTR, and at present they are practically not studied. In this work, for chemical reactions occurring in a closed non-isothermal IMR according to the kinetic law of mass action, linear concentration and temperature conservation laws are established, which take into account the complicating processes of diffusion and convection. These conservation laws relate the stoichiometry of the reaction mechanism to the concentrations of reagents, the temperature of the reaction medium and the intensity of macrokinetic processes, which allows them to be used for a more reasonable identification of linear and nonlinear mechanisms of chemical reactions when solving the inverse problem of chemical kinetics. The new kinetic conservation laws presented in the work can be discovered a priori and verified experimentally.

ASESSMENT OF THE EFFECTIVENESS OF CAVITATION PROCESSING OF DARK OIL PRODUCTS
Authors: Peshnev Boris V. , Burlyaeva Elena V. , Nikishin Denis V. , Nikolaev Alexander I. , Kuznetsov Andrey S.
Published: July 2024

The paper presents experimental results of the influence of the conditions of cavitation treatment of dark petroleum products in the hydrodynamic regime on the yield of fractions boiling up to 400 °C. Straight-run products (fuel oils, vacuum gas oils), as well as catalytic cracking gas oils, were considered as raw materials. The influence of raw material characteristics (density, fractional and group hydrocarbon composition) and its processing conditions (pressure, at five cycles of exposure) on the yield of the target fraction is considered. The linear dependence of the yield of the target fractions on the processing pressure is revealed. The constructed regression models are adequate, informative, and all their coefficients are significant. Taking into account the density of the feedstock did not improved models. The best model constructed was tested using the cross-validation method. The average forecast error was 11%, the maximum was 22%. For a small number of samples, such an error is acceptable. The possibility of assessing the effectiveness of cavitation treatment of crude oil based on data on its fractional and group hydrocarbon composition is shown. It was possible to build several regression models linking the increase in yield with pressure during processing and the content of resins and oils in the raw materials. All of them are adequate and informative, and their coefficients are significant. The increase in the yield of fractions boiling up to 400 °C is associated with the transformations of hydrocarbons during cavitation. The possibility of evaluating the effectiveness of cavitation treatment of petroleum raw materials based on data on its group hydrocarbon composition has been established. Several regression models have been constructed linking the increase in yield with the pressure during processing and the content of resins and oils in the raw materials. All of them are adequate and informative, and their coefficients are significant. Based on the constructed models, it is assumed that the change in the fractional composition of petroleum products during cavitation treatment is more associated with the destruction of the transition and solvate layers of complex structural units of the oil dispersed system than with the course of cracking reactions.

Published: July 2024

In the current work, we present results the study of synthetic transformations of substituted 3-thienylimino-3H-furan-2-one derivatives containing a nitrile substituent in the third position of the thiophene ring under the action of nucleophilic reagents. This class of compounds is of great for study due to the presence of several reaction centers in its structure, which makes it possible to obtain products of various structures, while retaining important pharmacophore groups - fragments of 2-aminothiophene and a fragment of 2,4-dioxobutanoic acid. We have synthesized and studied for biological activity substituted 2-(3-cyano-4,5,6,7-tetrahydrobenzo[b]thiophen-2-ylamino)-4-oxobut-2-enoates, which were obtained by a multistep synthesis method. The proposed method provides high yields of target compounds and includes the reaction of 4-aryl-2-hydroxy-4-oxobutanoic acids with 2-amino-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carbonitrile, followed by intramolecular cyclization of the resulting products under the action of propionic anhydride, as well as decyclization of the resulting substituted 3-thienylimino-3H-furan-2-ones under the action of primary alcohols. The structure of the finally isolated compounds was confirmed by 1H and 13C NMR spectroscopy and the elemental analysis. The resulting compounds were screened in vivo to detect and evaluate their biological activity and acute toxicity. Antinociceptive activity was studied in white outbred mice of both sexes by the hot plate test with intraperitoneal injection. Acute toxicity was studied according to the Pershin method, based on monitoring the condition of mice for 10 days after intraperitoneal injection of the test compounds. According to the results obtained, the tested compounds have a pronounced antinociceptive activity, and the assessment of acute toxicity indicates that they belong to the V class of practically non-toxic drugs. The high values of antinociceptive activity in combination with low toxicity make the considered substituted 2-(3-cyano-4,5,6,7-tetrahydrobenzo[b]thiophen-2-ylamino)-4-oxobut-2-enoates a highly promising class for further study in order to search for and develop new biologically active compounds with analgesic effect.

SYNTHESIS OF NEW γ-LACTONE RING DERIVATIVES CONTAINING PYRIDINE AND TRICONDENSED SYSTEMS

Published: July 2024

Lactone-pyridone rings contain many biologically active molecules of natural and artificial origin. The molecules contained in these two rings, represented by Cerpegine and its derivatives, will also exhibit high biological activity. It is also necessary to take into account that both natural and synthetic multi-substituted lactones have high biological activity. Thus, research in the field of multi-substituted lactones and further transformations are of particular interest. The synthesis of such systems began with the synthesis of a 2-acetylfuranone ring. In the next step, condensation of ethylcyanoacetate with 2-acetylfuranone by Knewenegel produced 3-substituted lactones, which according to the NMP 1H spectroscopy are a mixture of E and Z isomers. Then, when 3-substituted lactones were heated with dimethylformamide dimethylacetal DMFA/DMA, 3-substituted lactones containing a diene fragment in the structure were obtained. Stereoselective attachment E was detected using the NMR 1H spectrum. Then, under the action of the corresponding amine, the intermolecular substitution reactions produce compounds containing a lactone and pyridine group isolated by a σ-bond (serpegenous compound). Due to the proximity of the cyanide group of the pyridine ring and the fourth blight group of the lactone ring, intramolecular cyclization occurs during heating in the alkaline medium to form new tricondensed systems. Thus, an optimal method of synthesis of serpegenous compounds has been developed. These systems are of interest because in their skeleton they have not only a condensed system but also spirocycles. The connections themselves may be a promise for further exploration.

The investigation comprising of thirty genotypes of knolkholwas carried out at Vegetable Research Farm, SKUAST-J,Main campus, Chatha, J & K to study the extend of geneticdivergence for various quantitative and quality traits ofknolkhol during the year 2016-17. Based on the performanceof genotypes in the main season thirty genotypes groupedinto six clusters of which cluster I accommodated 12genotypes, while cluster V and VI were solitary. Intra clusterdistance was maximum for cluster III (122.44) followed bycluster IV (104.23) and the maximum inter cluster distancewas observed between cluster II and cluster IV (1182.73)followed by cluster I and IV (723.99). A considerable geneticdifference for cluster means of genotypes was observedbetween the groups during main season. The genotypesfalling in cluster IV recorded maximum cluster mean valuefor number of leaves per plant (11.18), marketable knobdiameter (7.37 cm), marketable knob weight/plant (380.29 g/plant) and yield/plot (5.11 kg/plant); cluster I gave minimumvalue for days to marketable maturity (50.10) and cluster VIgave maximum cluster mean for most of the quality traitssuch as beta carotene contents of knob and leaves, ascorbicacid contents of knob, calcium content of knob and leaves,potassium content of knob and leaves and phosphorouscontent of knob and leaves. Hence, crosses betweengenotypes selected from these clusters may be used togenerate knolkhol genotypes with good yield and qualitytraits.

Crop diversification in the form of including different cerealand horticultural crops in the cropping sequence can providefarmers with better income realization & profitability, resourceuse efficiency and productivity. Hence, a field experimentwas conducted to diversify and select suitable vegetablebased cropping system/sequence in Indo-Gangetic plain ofEastern Uttar Pradesh. Adequate intercultural operations,soil amendment and soil treatment along with proper fertilizermanagement produced higher crop yields. The vegetableyield during rabi season in the system where wheat wasreplaced by vegetable after rice ranged from 92.35 q/ha (Pea)to 407.1 q/ha (tomato). Rice equivalent yield (REY) in thecropping sequence where two vegetable crops were takenwas 177% (Rice-broccoli-cowpea) and 115% (rice-pea-okra)higher than the rice wheat cropping sequence. Under uppermidland situation the highest gross return (Rs 463736/ha)was recorded under okra -tomato- cowpea sequencehowever, the highest net return of Rs 261802 /ha and benefitcost ratio 2.43 was obtained in maize pea-pumpkin croppingsequence. Under low midland situation the highest grossreturn (Rs 459505/ha) and net returns (Rs 249955/ha) andbenefit cost ratio (2.20) was obtained in rice-broccoli-cowpeacropping sequence. Hence, it is suggested andrecommended that intensive vegetable-based croppingpatterns are suitable for small & medium farmers. Growingof three seasonal vegetables in a year and inclusion ofvegetables into the rice-wheat cropping pattern couldincrease the cropping intensity and productivity andeconomic returns.
Effect of organic sources of plant nutrients on yield, quality and nutrient uptake in onion
Authors: Shine KG , Bhalekar MN , Pawar PK , Patil BT
Published: July 2024

Onion (Allium cepa L.) is an important commercial crop grown worldwide. Now-a-days organically grown vegetables have more consumer acceptance and there is increasing demand of organically grown products. Organic farming is one among the broad spectrum of production methods that are supportive of the environment. Organic production systems are based on specific standards precisely formulated for food production and aim at achieving agro-eco systems, which are socially and ecologically sustainable. It is based on minimizing the use of external inputs through use of onfarm research efficiently compared to conventionalfarming. Thus the use of synthetic fertilizers and pesticides is to be avoided (Sivaraman 2007). Organic manures play an important role in improving soil physical, chemical and biological properties. The adoption of vermicompost helps in minimizing use of chemical fertilizers to the extent of 25-50% and increases the crop yield by 15-20% due to increased supply of essential elements (Marinari et al. 2000 and Singh et al. 2013)

Bitter gourd or bitter melon is undoubtedly one of the most significant members of the cucurbitaceous vegetable crops. Through the exploitation of this highly potential crop, novel mechanisms and strategies can be developed that will open the wide arrays for further improvement. Keeping this objective in mind, a field investigation was conducted with twenty genotypes of bitter gourd at Vegetable Research Farm of Banaras Hindu University to estimate the character association as well as direct and indirect effects of different yield traits on average yield per plant through correlation and path coefficient analysis. The data demonstrated that the positive and significant interrelationship with average yield per plant was obtained by various traits, viz., node number of first staminate flower (0.375), node number of first pistillate flower (0.54), vine length (0.417), fruit length (0.356), fruit circumference (0.79), average fruit weight (0.768), fruits per plant (0.637), and internodal length (0.3) while negative significant correlation was followed by days toanthesis of first staminate flower (-0.331) and days to first harvest (-0.355). The average fruit weight (0.572) had highest direct positive effect on average yield per plant followed by traits like days to fifty per cent flowering (0.296), number of fruits per plant (0.274), and number of primary branches per plant (0.259) whereas maximum direct negative effect was recorded by days to anthesis of first staminate flower (-0.263) followed by internodal length (-0.162) and days to first harvest (-0.152). The traits with high positive direct effect should be more prioritised for effective selection of promising genotypes for further crop improvement programmes.

The effects of different doses of exogenous jasmonic acid (JA), were investigated on physiological parameters such as germination percentage, root length, root number and fresh weight, cytogenetic parameters such as mitotic index (MI), micronucleus (MN), frequency and chromosome aberration (CA), biochemical parameters as such superoxide dismutase (SOD), catalase (CAT), malondialdehyde (MDA) and proline (PR) contents of Allium cepa L., known as onion. In addition, the changes in the root anatomical structures of the bulbs were examined under the microscope by taking cross-sections. Onion bulbs were divided into four groups as one control (C) and three treatments. The bulbs of the C group were kept in cuvettes containing tap water for 7 days and the bulbs of the treatment groups were kept in cuvettes containing 100 µM, 250 µM and 500 µM JA. JA administration caused a decrease in all physiological parameters examined, an increase in the frequency of MN and CA, and a reduce in MI compared to group C. In addition, the mentioned application caused a dosedependent increase in CAT and SOD activities and MDA and PR contents compared to group C. Moreover, 500 µM JA, the highest application dose, caused quite significant damages such as giant cell nucleus, unclear vascular tissue, binuclealar cell and accumulation of some substances in the cells of the epidermis/cortex in root anatomical structure of the bulbs. In summary, it was concluded that JA is a chemical with inhibitory functions and the Allium cepa test is a useful bioindicator for monitoring these effects.
