The bulletproof vest material that is often used is a composite material. Composites are a mixture of two or more material elements, with different mechanical properties, which aim to obtain new materials that have better mechanical properties than the constituent materials. One alternative mixture of materials in composite materials is to use natural fibers as a substitute for kevlar fibers. In Indonesia, which has a tropical climate, natural fibers are very easy to obtain from various kinds of plants found in Indonesia. Along with the many plants obtained, a lot of waste is also produced because of this. So research was conducted on the utilization of the potential of natural fibers for alternative composites. With the experimental method, from the results of the experiment, the results obtained from the five natural fibers that have been discussed, namely pineapple leaf fiber, water hyacinth fiber, bark fiber, hemp fiber, and bamboo fiber, only pineapple leaf fiber has not met the National Institute of Justice (NIJ) standard, while the other four natural fibers have met the NIJ standard for bulletproof vests.

There are a lot of scientific and research reports dedicated to Armenian architecture from the ancient times to nowadays. There are many interesting and thoroughly researched reports of architectural and historical value done by not only Armenian but also foreign historians, architects, and engineers. Exploring Armenian architecture’s chronology and research reports, we noticed that after independence of the Republic of Armenia (since 1991) there are few scientific reports which include the stages of development of architecture of newly independent Armenia, the current state of the architectural heritage and their observance. So we decided to study that period trying to show the problems and essential events as well as to introduce that period by the stages of development also including some examples of architectural heritage.

Heat exchangers are used to transferring energy (heat), using fluids or gases, both hot and cold, from one area to another due to temperature differences. Almost all agricultural wastes serve as carbon products which are essential to produce graphene oxide, it is very possible to get graphene oxide by synthesizing it from agricultural waste which is expected to reduce the amount of waste on the earth. After carrying out the synthesis, it is necessary to test the characterization of the resulting product. The characterization stage requires a sintering process (20oC to 98oC) until the product is completely solidified. This research aims to design a heat exchanger that is highly effective in assisting the sintering process. For the design to be well-directed, several things must be done, such as calculating the main components (shell and tube) and designing a heat exchanger. Based on the TEMA standard and the use of simple calculations that refer to the attached calculation formula using Ms. Excel, hot and cold fluids used in this heat exchanger design are ethylene glycol and water. The length of the shell and tube as a whole is 5 m, the inner and outer shell diameters are 254 mm and 279.4 mm; the inner and outer tube diameters are respectively 22.09 mm and 25.40 mm. The calculation results show an excellent design effectiveness value of 86.14%. Continuous innovation in the design and materials of the heat exchanger can increase the effectiveness value to close to 100% so that it can help the graphene oxide synthesis process to make it cheaper and more efficient.

The authors investigate the issue of modelling the balance of sustainable growth determinants based on determining the center of mass. They have identified the most relevant factors that characterize countries' social, economic, and political spheres, digital capability, and cybersecurity to determine sustainable development and growth. The research has been carried out based on empirical values of the selected 17 indicators for 127 world countries in 2018. As a result, the four–pole barycentric models were built as quadrangles, the vertices of which are composite targets formed by the determinants of the four spheres. The models' calculations were carried out taking into account three components: the values of the composite targets (as a geometric mean), the level of pairs balance (as the sum of opposite pairs of quadrilateral angles), and all four targets (as the distance between the actual and standard value of the center of mass). According to the analysis result of the first component, developed countries have the most effective targets (top five – Switzerland, Denmark, Norway, Finland, and the Netherlands). Research of the results of the second component has revealed an imbalance in target pairs for most countries. Determinants of socio–political development are the most effective for developed countries. The economic sphere is most unbalanced for the least developed countries. Various determinants can cause an imbalance for developing and new industrial countries. The analysis of the center of mass distances revealed that not only developed countries could be balanced, but also developing, new industrial and the least developed, which indicates a balanced development of their determinants, which is pretty slow. New Zealand, Mauritius, South Africa and Mali were the most balanced in each country's sustainable growth group.

The study is aimed at the molecular identification of ravine soil fungal isolates and their volatile organic compounds (VOCs) profiling. Chambal ravines of Morena, located at latitude 26?5?N and longitude 78?0? E at an elevation of 177 meters. Ravine soil is marked for depleted nutrients. The isolates were identified by macroscopic and microscopic examinations followed by molecular identification the extracted fungal DNA was amplified for specific internal transcribed spacer primer (ITS1/ITS4). The products were sequenced and deposited in GenBank (NCBI), sequence similarity was checked and a phylogram was constructed. The isolates were identified and named Porostereum sp. HGBS16 and Neurospora sp. PAMS29. The VOCs/bioactive molecules were allowed to produce under static submerged fermentation. VOCs/bioactive molecules extracted with polar solvent and characterized by GCMS analysis. Besides playing an active role in communication, the obtained VOCs have other useful attributes of industrial and other beneficial uses. The prevailing compounds produced by Neurospora sp. PAMS29 is octasiloxane (50.32%) followed by the production of octadecane (42.67%) and cyclopentasiloxane (7.01%) whereas Porostereum sp. HGB16 displayed bicyclo (2.2.1) heptane-2-one (86.09%), followed by dodecane (6.09%) and tetradecane (4.05%). The VOC octadecane is reported as a pheromone, a chemical messenger which is useful for mating in fungi. The Presence of octadecane confirms that Neurospora sp. PAMS29 used Pheromones as the mating messenger. Both fungal extracts showed the presence of vitamin C under screening test and exhibited good DPPH free radical scavenging activity with 76.74±7.81 inhibition by Porostereum sp. HGB16 whereas Neurospora sp. PAMS29 showed 82.1±6.47 percent inhibition activity. Results showed that the VOCs produced by fungal isolates have the potential for industrial uses and can be used in body care products in place of synthetic polysiloxanes, though the D5 is already reported to be used in cosmetics. This study introduces new fungal strains and their VOCs to the microbial research domain. Simultaneously the isolates are producing vitamin C and also exhibited the DPPH free radical scavenging activities. Both isolates are aromatic therefore it can be used in the perfume industry. Concluding, this is the first attempt at molecular identification of ravine soil fungal isolates and exploration of their VOCs. These results supported that VOCs are not waste products, they are very useful products at a certain level.

One uses the model which has been already presented in articles by the author: competition through prices (Bertrand competition), the demands being deduced from the consumers ‘utilities. One can highlight three phenomena: “Monopolistic competition”: The products sold are enough differentiated, each firm having its “garden”, its customers it keeps provided its price is not higher than the others’ prices. The criterium “buy and close down” profitable: when to buy and close down is profitable, the incentive to merge is stronger. It is a sign of saturated market. The “non-differentiating innovation”: One can model it. Each utility (u1, u2, u3) becomes (u1 + K, u2 + K, u3 + K), K > 0. One demonstrates, thanks to tractable examples, that non-differentiating innovation can trigger the criterium “buy and close down profitable”. The products are less differentiated than at the start (“monopolistic competition” the “buy and close down” being not profitable). It incites firms to choose disruption.

The lack of resource constraints for edge servers makes it difficult to simultaneously perform a large number of Mobile Devices’ (MDs) requests. The Mobile Network Operator (MNO) must then select how to delegate MD queries to its Mobile Edge Computing (MEC) server in order to maximize the overall benefit of admitted requests with varying latency needs. Unmanned Aerial Vehicles (UAVs) and Artificial Intelligent (AI) can increase MNO performance because of their flexibility in deployment, high mobility of UAV, and efficiency of AI algorithms. There is a trade-off between the cost incurred by the MD and the profit received by the MNO. Intelligent computing offloading to UAV-enabled MEC, on the other hand, is a promising way to bridge the gap between MDs' limited processing resources, as well as the intelligent algorithms that are utilized for computation offloading in the UAV-MEC network and the high computing demands of upcoming applications. This study looks at some of the research on the benefits of computation offloading process in the UAV-MEC network, as well as the intelligent models that are utilized for computation offloading in the UAV-MEC network. In addition, this article examines several intelligent pricing techniques in different structures in the UAV-MEC network. Finally, this work highlights some important open research issues and future research directions of Artificial Intelligent (AI) in computation offloading and applying intelligent pricing strategies in the UAV-MEC network.

Due to its diverse cultural heritage and rich natural resources, Bosnia is lately becoming more popular among foreign visitors. Currently, many tourists are increasingly focusing on outdoor and rural tourism. To be able to fulfill their needs in terms of accommodation and activities, during the last several years many ethno villages are built throughout the country. The design of such artificial ethno villages often borders on kitsch and does not represent authentic architectural styles of the region. Some of them, as introduced in this paper, tend more towards mass tourism and luxury accommodation offers that are in contradiction to the idea of ecological ethno villages. On the other hand, many villages in the country are partly or entirely abandoned due to the population displacement into cities. This paper aims to compare the touristic offer and quality of the newly constructed ethno villages as a new form of rural tourism with existing, vernacular villages in the country. The research is a comparison study, also addressed by the analytical-historical method with the auxiliary method of the case study which incorporated recordings of site conditions. The focus of this research is the village Idbar and its prospects that offer a solid base for further development of ecological ethno tourism in Bosnia and Herzegovina, which could potentially become one of the leading branches of rural tourism in the country.

This study analyzes the possibilities of preserving the form and renovating the historic mosque with a wooden porch and minaret, based on the Osman Cehaja Mosque in Tuzla as an example. The research is based on direct observation of property over several decades and a comparison of formal qualities with other relevant structures of a similar type and period. Except for its foundation, no information is available on its past or potential interventions. It is only reasonable to assert that it was originally covered with a wood shake. It is assumed that its appearance has not changed since the early twentieth century, based on a common memory. The mosque was renovated four years ago. Analysis of the previous and current appearances showed that the complete renovation did not compromise its form. In this respect, it is feasible to renovate the mahalle mosque with a wooden porch and minaret while preserving its historical character. More challenging cases may necessitate more extensive investigation, planning, and experience.

The way to improve the efficiency and effectiveness of public spending, which is a top priority for any government in any country, implies the introduction of Performance-Based Budgeting (PBB). One of the more advanced government-wide performance budgeting systems that uses performance information systematically in the preparation of the government budget is program budgeting. It is important to keep in mind that without systematic development and use of program performance information and adequate and effective performance indicators, program budgeting in the defense sector does not make sense as a tool to improve the efficiency and effectiveness of the defense resource management process. Only by defining and tracking success can it be known if the defense organizations and units perform efficiently and effectively. In this article, data envelopment analysis (DEA) was considered as an excellent mathematical programming tool that can be used to measure, evaluate, and analyze the efficiency of the defense organizations, in particular of the infantry battalions of the infantry brigades under the Eastern and Western Commands of the Georgian Defense Forces (GDF), on the delivery of readiness. A sample DEA model was proposed to measure the efficiency of the abovementioned units. Some recommendations to facilitate the use of the DEA and other statistical tools to measure and evaluate the performance of the GDF units were also proposed.

The objective of this paper is to put forward a holistic, less subjective, method to value built heritage. Based on 37 seminal publications issued from 1903 to date, 24 value typologies were identified, classified and incorporated in a heritage value grid developed from the Nara Grid. This grid allows for a multi-layered valorization of aesthetic, socio-cultural, economic and informational values with respect to six heritage dimensions, namely, (i) design, (ii) materiality, (iii) function, (vi) location, (v) tradition and techniques, and (vi) spirit and memory. This formed the basis of a mathematical formula, the Heritage Value Calculation, to compute the heritage value of a given building. The resulting final value is useful in the scheduling of such sites.

The Democratic Republic of the Congo is still experiencing internal political turmoil between the Tutsi and Hutu tribes. Therefore, the United Nations through the Security Council established The United Nations Organization Stabilization Mission in the Democratic Republic of the Congo (MONUSCO) to monitor the peace process after the Second Congo War. Several approaches must be applied so that the mission carried out is able to reconcile the conflicting actors. The purpose of this research is to find out the obstacles faced in the MONUSCO mission and their solutions. The method used in this research is to use a literature study to test the credibility of the data found. The peace mission carried out by MONUSCO can be said to be quite successful despite facing several strategic and operational challenges. The use of cultural intelligence and prospect theory in pre-mission training should be done in order to increase the success of the mission.

Airpower played a vital role in shaping the result of the Second World War. As a British colony, the Indian Sub-continent was targeted by Imperial Japan. The Japanese Forces came up to Myanmar (the then Burma) and their next target was the Indian sub-continent. Due to the geographical location Bangladesh (the then Bengal) was on the front line of British defense; as it was strategically important for Japan to occupy Bangladesh. As such, Bangladesh air space was highly contended by the belligerents. To support air operations, a good number of airfields were prepared by the British-led forces in the then Bengal. However, after the war, most of those airfields were abandoned. British left the region in 1947 and Bengal became part of Pakistan. Economic, strategic, and political factors did not permit the maintenance of those airfields and most were left as it was. Only Tejgaon airfield was used by Pakistanis for both civil and military aviation purposes. After the independence of Bangladesh in 1971, an effort was made to revive some of those airfields.

Cybersecurity is an important topic for Industry 4.0, which will face a lot of non-traditional challenges before it can be fully implemented to help society. The objective of the study is to recognize recent cybersecurity trends, newly occurring threats and challenges as well as their potential solutions. The articles reviewed in the paper are found through science direct, Scopus, Semantic scholar and google scholar. After reviewing them, ideas from articles were grouped together to show how different articles had similar thoughts. Through the analysis of 70 articles, it was found that cybersecurity still needs a lot of improvement in order to efficiently implement Industrial Internet of Things (IIoT), especially since many articles underline the need for security-by-design approach, followed by regular updating. Key challenges are lack of awareness and security experts, increased cybercriminal and the fact that the chain is as only as strong as its weakest point. Some of the most important solutions include incorporating security into design, stronger encryption, regular updates to patch vulnerabilities and good prevention and detection mechanisms. Once cybersecurity challenges are overcome, Industry 4.0 will be able to bloom to its full extent.

Nucleic acid analogues are used in protein synthesis, as their effects on gene expression are confirmed, and play a crucial and important role during transcriptional and posttranscriptional processes in the cell. Due to the many remaining challenges associated with genetic engineering, current research mainly focuses on new materials such as peptide nucleic acids [PNA] and locked nucleic acids [LNA]. PNAs and LNAs have been developed to mimic the chemical characteristics of DNA and RNA and to show improved properties. They represent synthetic DN/RNA analogues in which the phosphodiester backbone is replaced with unchanged aminoethylglycine units, being very resistant to enzymatic degradation by proteases and nucleases. This review summarizes the application of nucleic acid analogues in the inhibition of gene expression in bacterial genomes, as well as the usage in the development of high-performance affinity biosensors.

The millimetre wave (mmWave) is alleged as an important element invention to respond to the rapid increase in wireless demand for mobile traffic using its huge bandwidth. However, channel modeling remains difficult due to its high dependence on weather conditions and the positioning of the antenna for communication in direct visibility line-of-sight (LOS). Co-polarization and cross-polarization (X-pol) are two main events in the direction of the radiation element for wave transmission; where the wanted direction of wave transmission denotes the co-pol and the orthogonal propagation of the intended direction represents X-pol. This work investigates the effect of the polarization on a statistical channel modeling at 28 GHz, 38 GHz & 73 GHz mmWave channel using NYUSIM Model.

Historically, the engine crankcase has been made of gray cast iron due to that material's' high machinability, damping ability, thermal conductivity, and sensible cost. Despite these advantages and the long-term use of gray cast iron, the vehicle manufacturers predominately use cast aluminum as material of choice for the engine block due to aluminum’s density being almost a third of that of gray cast iron, and the aluminum engines have the same durability as gray cast iron while weighing considerably less. However, due to the low wear resistance of aluminum, efforts are needed to improve internal working surfaces such as the use of cast iron cylinder liners or the application of a protective coat is applied to the aluminum surface to increase its resistance. The purpose of this study is to examine which ring materials have the lowest friction with the Twin Wire Arc (TWA) aluminum cylinder liner. An Ansys simulation model accomplishes the experimental work. The steel ring material obviously had the lowest friction with twin wire arc spray aluminum cylinder liner as opposite to the cast iron material which was the worst.

Looking at the evolution of mobile phones, communications technology, and the Internet, one can see a clear shift in their usage in the past decade as mobile payment has become an important research area in the field of information technology. However, many financial institutions have adopted mobile payments. Except that only a limited number of clients are used. Several information systems theories/models have been proposed to examine the factors that could influence user adoption. However, the literature on the field is still in its infancy. This paper, reviews and systematically analyzes the existing mobile payment acceptance and adoption literature that include UTAUT/TAM as a theoretical model to reveal mobile payment adoption research's current situation. The current study also provides a basis for future researchers in the mobile payment adoption study, as it provides a summary of related literature in the field, the models used, and the factors that have an impact on customer intent. Accordingly, the UTAUT, TAM models, with their extensions, are one of the models most used in examining and understanding the necessary factors that could influence mobile payment applications' adoption. The research revealed that 37 factors most commonly than a literature review on factors of adoption mobile payment applications since 2015. It was found that the factors of perceived trust and perceived risks are among the most critical factors in which the models are expanded, as they have an impact on the customer's acceptance of any new technology innovation. Therefore, emphasis must be placed on the factors of perceived trust and perceived risks to increase the applicability of UTAUT, TAM models to the mobile payment context.

In many regions (e.g., Southeast Asia), palm kernels are a very economical feedstock for biomass energy production. However, the collection and transportation of palm kernels are complicated, which is not conducive to the further development of this industry. This paper analyzes the current situation of collection and transportation of palm kernels in Southeast Asian countries using basic analysis methods. Meanwhile, the characteristics of palm fruit bunches as biomass fuel and its transportation and handling methods are briefly introduced and analyzed concerning the fuel demand of biomass power generation projects. The shortcomings of the current methods were identified, and relevant directions for improvement were proposed. It is hoped that it can improve the transportation efficiency of palm fruit bunches as a feedstock for biomass power generation and provide a reference basis for the collection and transportation of palm fruit bunches biomass.

Our planet is in danger for a number of reasons such as population growth, excessive energy consumption, and global warming that followed, the inability to manage waste and reduce water consumption. For sustainability, green concrete is defined as the use of waste materials and high-sustainability concrete that does not harm the environment in the production process. Proper green building should be energy efficient and use recycled aggregates. The emergence of sustainable structures in this way will reduce the need for fossil fuels, which is the main reason for universal heating. The environment can be perfectly sustainable only with zero use of non-renewable resources and a limited rate of regeneration and controlled use of renewable resources. This study considers the concept of environmentally friendly green concrete, which can be used instead of the traditional cement used in buildings that are being built due to the growing population. It was examined what needs to be done for the sustainable design of buildings and it was pointed out that in that way the emission of carbon dioxide into the atmosphere will be reduced. The use of green concrete for sustainable design and environmental protection was highlighted and several examples from around the world were highlighted.

The impact of 3D printing parameters is critical for expanding the application of technology in the design and construction. The effect of bonding layers on the compressive strength of the material is investigated in this research by variation of the layer thickness and print speed. Cube specimens with layer thicknesses ranging from 0.05 to 0.3mm and print rates of 40mm/s, were tested on compression with the DARTEC test equipment. It was found that layer thicknesses of 0.05mm and 0.15mm have similar elastic properties while the 0.15mm layer can take additional load after initial plastic deformation. Layer thickness of 0.30mm has significantly lower elastic zone load capacity, but the stress in plastic zone continue to grow. The findings are of great importance for in explaining the S-N curve in order to enhance part manufacture.

Mineral fillers provide a significant role in the Marshall properties of hot mix asphalt for paving applications. The article's goal is to assess the suitability and effectiveness of two minerals (coal dust and wood powder ash) used as fillers in asphalt concrete. Chemical composition test using X-ray fluorescence indicated a high content of SiO2, Fe2O3, and Al2O3, which encouraged us to select the coal dust and wood powder ash as mineral fillers for further investigation. A total of 90 cylindrical Marshall Specimens, made with different percentages (i.e., 4%-8%) of coal dust, wood powder ash, and conventional stone dust filler were prepared to assess the performance of individual filler within the asphalt concrete mix. And after that, volumetric characteristics such as density, stability-flow test, air void, and voids in mineral aggregates have been analyzed to evaluate the effectiveness of every sample and, afterward, to find out the optimum asphalt content. Finally, the optimum asphalt content for every filler material was ascertained, and subsequently, Marshall properties were checked again to assess the optimum filler content in the mix that satisfy all the standard criteria. The overall Marshall properties for both fillers were within the acceptable limits. Though the optimum asphalt content was higher for coal dust than wood powder ash and stone dust, the wood powder ash showed better durability than coal dust. All mixtures have been found to have better resistance to deformation, fatigue, and moisture-induced damages; however, 4% coal dust and 6% wood powder ash satisfied most of the Marshall criteria than other percentages.

Maintaining the optimum temperature in the living quarters is the key to a comfortable stay. Due to the lack of a central heating system or in the event of its insufficiency, they resort to the installation of additional heat sources. There is a wide range of devices on the market with different operating principles, hence the difficulty of which is better - a convector or infrared heater. A comparative analysis of devices will help you make the right choice. Asking the question of which is better a convection heater or an infrared heater, one must decide on its role in heating the house. It is better to use them as additional equipment with an existing heating system. One of the effective sources of additional heating are infrared radiators. Its principle of operation is based on infrared radiation, which provides a quick and qualitative increase in temperature in any part of your apartment. Today, more and more people prefer infrared radiators. From the usual electric convector, they differ in that they heat not the air in the room, but hard surfaces (floors, walls) and objects, and these, in turn, leak heat into the surrounding space. So, the entire room is heated up unnoticeably.

The aim of this study was to determine the antioxidant capacity of some phytochemicals by using an H2O2 scavenging assay. Betaine, Allantoin and Nicotinamide were put to the test. Even though hydrogen peroxide (H2O2) is not intrinsically reactive, it can be transformed into the extremely reactive and harmful hydroxyl radical (HO), which is then able to interact with nucleotides in deoxyribose nucleic acid and in that way trigger breakage of the strand resulting in carcinogenesis, mutagenesis, etc. Antioxidants aid in the protection of cells from the harmful effects of reactive oxygen species that are known to induce oxidative stress. Excessive production of these reactive oxygen species in the human body is associated with many chronic degenerative diseases such as diabetes, neurodegenerative disease, cancer, etc. The effective way to minimize levels of oxidative stress is the ability to scavenge these reactive oxygen species (ROS). Also, phytochemicals are able to act as antioxidants, and in that way play a vital role in the prevention of disease caused by oxidative stress. The ability of a compound to scavenge H2O2 is a good predictor of its potential antioxidant function. The hydrogen peroxide (H2O2) scavenging assay was determined using the Ruch et al., 1989 method, and a UV-VIS spectrophotometer. In conclusion, our samples had marvellous H2O2 scavenging activity and possessed good antioxidant capability, and were compared with the ascorbic acid (vitamin c) as standard natural antioxidant/ as reference antioxidant. The samples were also able to scavenge H2O2 in a concentration-dependent way, according to our results

Explosively formed projectile (EFP) is a self-forging shape charged structure having very high penetration ability compared to conventional kinetic energy projectile. The penetration capability of an EFP is strongly dependent on various design parameters. The main parameters can be roughly divided into geometric and material parameters used in the warhead configuration. The present research is an effort to study the effect of metal casing thickness, type of metal used for casing, explosive type, liner thickness, type and configuration on the formation of EFP. Effectivness of an EFP is studied in terms of final velocity and shape of formed penetrator. The study is carried out by performing a number of simulations by using explicit finite element (FE) hydrocode ANSYS/Autodyn.

In the last twenty years, high energetic materials have changed significantly. Several factors have influenced the development of these materials, which include new operational requirements such as insensitive ammunition (IM), as well as factors in the availability of new materials and new production techniques, safety assessment, and modeling. All this enables more efficient use of materials and a more detailed understanding of the processes involved in the application of new technologies. This work presents new insensitive secondary high explosives such as TATB, FOX-7, GUDN, NTO, and others that are in different stages of development. A review of these explosives is given and their stability, reliability, and specific application are described. Energy materials are known to be chemical compounds or mixtures that contain significant amounts of energy and it has been shown that successful design of new energetic materials with customized performance properties and increased stability is possible. The properties of new insensitive energetic materials must be further researched and improved before they can be used in new or existing systems. Insensitive ammunition testing is a vital component of many national IM programs. The international community has established requirements for testing the insensitivity of materials and developed six unique tests based on testing the response of the material to the effects of heat, impact, or shock.
