Kultura osiguranјa i nјegovi aspekti u Republici Srbiji i drugim zemljama
Authors: Bataveljić Dragan , Petrović Bojan
Published: September 2023

In the paper, the authors indicate the concept of insurance culture and the importance of insurance in the life of every person. The fact is that man has always been exposed to numerous risks. This applies both to his life and his property. We find the beginnings of insurance 5,000 years ago in ancient China. These were the initial forms, and we meet more complex forms of insurance and the first policies at the end of the 12th century in Italy and medieval Serbia in the 14th century. Insurance is constantly influenced by the economic and social system. It experienced the greatest negative impact in the Republic of Serbia during the nineties of the 20th century due to unprecedented hyperinflation. Unfortunately, the development of the insurance culture in the Republic of Serbia is at a low level compared to the member states of the European Union. However, the economic growth of the Republic of Serbia is evident, which should enable a decrease in the number of concluded insurance contracts, especially life insurance. Education at all levels should also contribute to this.

The National Security and Intelligence Nexus in Nigeria: A Historical Analysis
Authors: Bot Danladi
Published: September 2023

Since the return to democracy in 1999, security has been a major issue in Nigeria in view of the continued ethno-religious conflicts, insurgency & terrorism, banditry, kidnappings, pipe-line vandalization and oil bunkering, sea piracy, and militancy that have continued to occur in the country. The detrimental effects of these national security challenges, has forced government and academics to direct their attention towards finding feasible solutions to Nigeria’s security conundrum. A close examination of existing academic works on National security challenges in the country reveals that very little attention has been paid to the understanding of the role of intelligence as a panacea or as a catalyst that has exacerbated insecurity in the country. In light of this, this paper examines the marriage between intelligence and national security. Focusing also, on the symbiotic relationship between the two and how they both work to reinforce or undermine each other. Methodologically, the paper adopted descriptive and analytic approach. Data for the paper was sourced through the secondary means of data collection. The study reveals that in Nigeria’s quest to establish sound intelligence and national security policies, it has not been able to fully take cognizance of its micro security, macro security and strategic security, and address adequately, the concerns therein. It also found out that, failure to gather intelligence comprehensively by the Nigerian intelligence services (using the full complements of their intelligence gathering paraphernalia) and also, failure to act in a timely fashion, to received intelligence, has sometimes been the reason why some violent altercations in the country have endured. Based on this, the paper recommends among others that for intelligence to be successful in reducing insecurity in Nigeria, the intelligence related services in the country, need to synergize their efforts in the promotion of Nigeria’s national security strategy. Hopefully, this research study could assist various stakeholders in policy making when it comes to the application of intelligence in dealing with national security threats.

Authors: Sriwijaya Yong Richard , Pratama Harbi , Adinata Indra , Mayangsari Tirta Rona
Published: September 2023

Non-conventional crude oil has 70% of total heavy crude oil reserves and potentially as an energy source. The enhancement of non-conventional crude oil production can be done by utilizing the Enhanced Oil Recovery (EOR) technique with aquathermolysis reaction. The nanocomposite of Activated Hematite-Zeolite has the best properties as a catalyst to provide aquathermolysis on crude oil. These materials were successfully synthesized by using the microwave-assisted co-precipitation method. The XRD pattern represents mixing both hematite and zeolite in mordenite structure at 2θ equal 6.57o; 9.77o; 19.65o; 22.36o; 25.72o; 26.36o and at 30.1o; 35.6o; 40.9o, respectively. A reduction in a viscosity of crude oil occured after the aquathermolysis test was run by nanocomposites about 30.03% and simultaneously enhance the ratio of C-H saturated. Hence, it had improved crude oil quality with larger molecules in crude oil divided into small molecules due to breaking C-C bonds.

Authors: Prayogi Soni
Published: September 2023

In this study, we report that N-type hydrogenated amorphous silicon (a-Si: H) was grown with the addition of H2 using the Plasma Enhanced Chemical Vapor Deposition (PECVD) technique. The deposition was carried out for several process parameters including deposition time, gas pressure, and substrate temperature with the aim of obtaining a thin a-Si: H layer which has effective optical properties for solar cell materials. To indicate the nature of this semiconductor, the optical band gap is measured. From the measurement using Tauc's Plot method on the absorption data of the UV-Vis spectrum as a function of wavelength, the optical bandgap energy of the thin film was obtained. While the thickness of the thin layer was characterized by using Atomic Force Microscopy (AFM). The characterization results show that the optical band gap energy is 1.8 eV and the thickness of the thin film formed is 72 nm.

Published: September 2023

Thermophilic microorganisms can survive and live in extremely high-temperature habitats. This special trait made thermophilic microorganisms have heat-resistant proteins such as thermostable enzymes and have been used by the industry as biocatalysts. Some advantages of using thermostable enzymes in the industry are reducing operating costs, increasing the reaction rate, increasing productivity, and being environmentally friendly. This research aims to isolate the thermostable enzyme encoding gene and determine homology, differences in the sequence, and the closest relative of samples. The metagenomic approaches using random PCR techniques were used as a methodology in this research. The substances successfully obtained from random PCR of the metagenome samples were cloned in the cloning vector and then analyzed nucleotide sequence (sequencing). The highest protein homology in samples 23 and 24 are Short-chain Dehydrogenase Reductase (SDR) oxidoreductase [Caldivirga maquilingensis] of 58.58% and 58.02%, respectively. The 3-dehydroquinate dehydratease Type I [Metallosphaera] is the highest protein homology in sample 45, with a similarity of 79.88%. The phylogenetic tree analysis of sample 23 has the closest relationship with sample 24. Meanwhile, sample 45 has the closest relationship with 3-dehydroquinate dehydratase Type I from Metallospaera species. The three samples formed different branches with other amino acid sequences, showing that the three samples are new enzymes that are different from the previous ones.

Published: September 2023

Electric power is vital in supporting the economy of current society. Electric power can be obtained from water. Water is one of renewable energy that can be used as hydropower to produce electrical energy. The electric energy can be produced from a generator driven by a waterwheel, which means the electric energy comes from the kinetic energy of water. One of the most common sources for flowing water is from the water tap. The electric power that could be produced from flowing water with a restriction that the water flow only affected by gravitational force and come from a finite resource. In this research, a mathematical model of electric energy or electric power are developed based on kinetic energy. The change of kinetic energy with time is electric power. The mathematical model is solved numerically to find power using the Euler method; therefore, this model is able to obtain power with changes in time. The result test show that the power greatly affected by the volume and height of water. The volume and height of water are decreasing over time and also the kinetic energy and power produced from water flowing out from the water tap reduced exponentially with respect to time.

Plattformarbeit
Authors: Söller Martin
Published: September 2023

In this volume, Martin Söller structures and systematises the sometimes confusing wealth of information on platform work. In particular, he sheds light on the multilateral and multi-layered contractual relationships inherent in this new form of work and the status of platform workers under labour law. In doing so, he addresses the definition of employee and arrives at the central question of when the discontinuity of work performance associated with platform work reaches such a high level that the service provider's status as an employee is lost. At the same time, he clarifies numerous connections that have so far remained hidden, so that the volume can also serve as a comprehensive handbook on platform work.
Das Kostüm bei Hans Makart
Authors: Weitner Bettina
Published: September 2023

Der vorliegende Band untersucht Hans Makarts (1840–1884) Auseinandersetzung mit Geschichte anhand seiner malerischen Darstellung historischer Kostüme. Diese sind in ihrer kostüm- und kunstgeschichtlich höchst dissonant zueinander stehenden Ausarbeitung als „Schlüssel“, nicht nur für das Geschichtsverständnis des Künstlers, sondern auch für das spezifische Historienverständnis in der zweiten Hälfte des 19. Jahrhunderts zu verstehen.

Ausgehend von den beiden Historiengemälden „Venedig huldigt Caterina Cornaro“ (1872–1873) und „Der Einzug Karls V. in Antwerpen“ (1878) arbeitet die Untersuchung die Quellen und Bildvorlagen des Künstlers systematisch heraus. Erschlossen wird dabei auch der private Sammlungsbestand des Künstlers und seine im Atelier und im Wiener Künstlerhaus ausgerichteten Kostümfeste, die Makart als Inspirationsquelle seiner Historienbilder dienten und den Nährboden für die Verflechtung von „Kunst und Leben“ bildeten. Die Untersuchung bedient sich dabei einem breiten kulturwissenschaftlichen Zugriff, um die Verbindungsstränge zwischen Kunst und Gesellschaft offen zu legen und Makarts Historienverständnis im Kontext von Malerei, Fest- und Kleiderkultur, „Lebenden Bildern“ sowie dem Theater zu beleuchten.

A Review on Vegetable Oil Refining: Process, Advances and Value Addition to Refining by-Products
Authors: Sonawane Anup , Waghmode Samadhan
Published: September 2023

Nowadays, consumer food choices are driven by health awareness and sustainability concerns. As vegetable oil is an important component of the human diet, the source and the processing play an important role in consumer acceptability. To remove impurities that affect the color, palatability, stability, and safety of oil, crude vegetable oil must be refined. This review highlights the processes and steps used in vegetable oil refining. Depending upon the oil source type, either chemical or physical refining is employed to get the desired oil specifications. Oil refining steps are sequential, with each step removing one or more specific impurities. Refining advances aim towards minimizing chemical usage, nutrient losses, oil losses, and avoiding the formation of trans-fatty acids. The review also discusses the prospect of using the refining by-product stream for obtaining high-value products like phosphatidylcholine, tocopherols, and tocotrienols. The edible oil industry can be made more economical and sustainable through the valorization and integration of waste product streams obtained at different refining steps.
Aromatic Plants: Alternatives for Management of Crop Pathogens and Ideal Candidates for Phytoremediation of Contaminated Land
Authors: Banda Maria , Munyengabe Alexis , Augustyn Wilma
Published: September 2023

Crop diseases due to fungal pathogens cause significant resulting economic losses in agriculture. For management of crop diseases, farmers use synthetic pesticides. However, the frequent application of these chemicals leads to accumulation in soil and therefore presenting pollution problems. Essential oils (EOs) sourced from aromatic plants are safer alternatives and are effective against a variety of crops pathogens. In addition to their role as the sources of EOs, aromatic plants are gaining much attention in rehabilitation strategies. In phytoremediation processes, suitable plants species are used to clean-up polluted sites. Mining activities and electricity generation processes have resulted in significant amounts of tailings and coal fly ash. Mine tailings and coal fly ash are disposed in dumpsites, converting productive lands to unusable waste sites. These solid waste materials contain toxic metals and therefore posing serious risks to the health of the environment. Aromatic plants can be cultivated in contaminated sites and therefore be used for restoration of polluted lands. The EOs can be sourced from these aromatic plants as they are free from metal-toxicity and can therefore be used to generate revenues. This review highlights the role of aromatic plants in the control of crops pathogens and also their application in phytoremediation processes.

Published: September 2023

Bacillus is a genus of gram-positive bacteria that is widely distributed in the environment. The species of this genus present in the endosphere, phyllosphere and rhizosphere in the plant and perform as a beneficial biocontrol agent and promote plant health. These strains exhibit diverse capabilities, including the potentiality to directly suppress the germination of microbial, stimulate plant development, reduce pathogen infections, degrade different types of hydrocarbons, function effectively across a wide temperature range, and induce immune resistance in host plants. The species/strains of Bacillus genus have proven promising biocontrol agents against a large number of fungal and bacterial causal organism, as well as plant-damaging insects. They induce a wide range of composites with antifungal properties, such as iturin, surfactin, cyclic lipopeptides, bacillomycin, bacteriocins, polyketide, lentibiotics, phospholipid, polyketide microlectine, isocosmarin and amino sugar. These compounds play a crucial role in preventing and controlling diseases in plants. The synthesis of these compounds is initiated in response to the presence of bacterial and fungal pathogen biomass and their cell walls. The purpose of this review is to offer a thorough exploration of the disease suppression mechanisms utilized by Bacillus, with a specific emphasis on their function as plant growth-promoting rhizobacteria (PGPR).
