Since the beginning of operations in 2014, Port of Açu has shown significant growth in relation to cargo handling, with all demand dependent on road transport. However, there is a proposal for the implementation of the EF-118 railway that would interconnect Rio de Janeiro and Vitória, serving the region of Port. This work seeks to economically evaluate the advantages of the implementation of the railway modal compared to the roadway already used in the region. Due to the intense flow of cargo in the Industrial-Port Complex, the possibility of building a new highway, the RJ-244, is being studied, extending from the industrial district to BR-101. For this purpose, surveys were conducted to determine the average daily volume of vehicles circulating in the region, in addition to the different types of cargo transported and their relationship with Port. Based on the information collected in the Traffic Studies Report issued, it was possible to relate data and achieve at the value of the average annual daily volume for each category of cargo handled in the Port. Bearing in mind that in 2019, Port of Açu handled approximately 751 thousand tons of cargo and analyzing the estimated costs by ABIFER for road and rail transport, the approximate cost values for each one per ton of cargo per kilometer were reached. Comparing values, it is possible to notice that the cost of transporting cargo by rail corresponds to about 16.6% of the amount spent on transporting of the same weight of cargo by road, which means a considerable advantage for its implementation.

The Impact

The article presents an outline of the law governing railway transport in comparison with the regulations for road transport. The comparison shows that railway entrepreneurs are much more encumbered with legal obligations than road carriers, which in part is due to the specificity of this branch of transport. The essential constraints to the competitiveness of railway transport relate to the cost of access to railway infrastructure and its condition. The article also points out the faulty legislation, disadvantageous to both modes of transport, and attempts to determine the impact of legal solutions for the development of rail transport.

The article deals with the distribution of agricultural periodicals on the territory of the Russian Em-pire in the early twentieth century. Before that there were practically no publications on the pages of sci-entific magazines. Great emphasis is placed on the analysis of agricultural magazines published before 1917 in the Upper Volga region, namely in Vladimir, Kostroma, Tver and Yaroslavl provinces. Thanks to existed in pre-revolutionary Russian periodicals on agricultural subjects advanced knowledge of agron-omy, agriculture, soil science, horticulture, fruit growing, vegetable growing, winemaking, viticulture, 135 tobacco growing, livestock, poultry, bee-keeping, veterinary medicine, forestry, and hunting, land man-agement, irrigation, horse breeding were promoted. On the basis of statistical data, office documentation and other published sources, the author draws conclusions about the degree of accessibility of agricul-tural periodicals for the population, including the peasantry. Availability of agricultural periodicals largely depended on its price, so the author studied the situation with the cost of the annual subscription fee of these publications. The article investigates the issues of periodicity of agricultural magazines and newspapers, the exact number of such publications, as well as their subject matter. Existence duration of different types of periodicals is analyzed, the main publishers of magazines and newspapers, places of their publication are revealed. A prominent place is given to the publishing activities of agricultural pub-lic organizations and zemstvo self-government bodies. It is concluded that natural process of agricultural knowledge distribution among the population of Russia through publications on the pages of periodicals was disrupted by revolutionary events of 1917.

The use of anti-forensic techniques is a very common practice that stealthy adversaries may deploy to minimise their traces and make the investigation of an incident harder by evading detection and attribution. In this paper, we study the interaction between a cyber forensic Investigator and a strategic Attacker using a game-theoretic framework. This is based on a Bayesian game of incomplete information played on a multi-host cyber forensics investigation graph of actions traversed by both players. The edges of the graph represent players’ actions across different hosts in a network. In alignment with the concept of Bayesian games, we define two Attacker types to represent their ability of deploying anti-forensic techniques to conceal their activities. In this way, our model allows the Investigator to identify the optimal investigating policy taking into consideration the cost and impact of the available actions, while coping with the uncertainty of the Attacker’s type and strategic decisions. To evaluate our model, we construct a realistic case study based on threat reports and data extracted from the MITRE ATT&CK STIX repository, Common Vulnerability Scoring System (CVSS), and interviews with cyber-security practitioners. We use the case study to compare the performance of the proposed method against two other investigative methods and three different types of Attackers.

This paper proposed a scheme design for Sydney’s frontport check-in system, which completes check-in and baggage drop-off at Sydney’s Circular Quay, and transports the baggage to Sydney Kingsford Smith Airport by waterway, and provided a strengths, weaknesses, opportunities and threats (SWOT) analysis of Sydney’s frontport check-in system. Using the process method of quality management, the frontport check-in process was divided into three sub-processes: baggage consignment, baggage packing and transportation, and airport baggage handling. The eight key elements of each sub-process such as input, output, resources, and methods, etc. were discussed, the key factors influencing the cost of baggage transportation were analyzed, and the cost control measures such as adopting economic speed, reducing fuel consumption of the main engine, improving the ship loading rate, and raising loading and unloading efficiency were proposed. At the same time, two different types of baggage transportation ships and other parameters that affect the cost such as the number of berths, ships, lifting machineries, and the yard area were analyzed and calculated through calculation cases. This scheme is a beneficial addition to the existing in-town check-in system.

Space Segment

The article provides a method for calculating the costs when designing a promising embodiment of a low-bit satellite system. For Ukraine, the prospects for this option lies in the fact that their own means of achieving a large number of satellites in orbit are applied. At the same time, satellites are multifunctional and used to organize communication and broadcasting, the sounding of the atmosphere and the surface of the Earth, subsurface locations, cosmic observation, data collection from the Internet sensors. The space group consists of mini, macro-, nanosterans, which are delivered to the orbit of a domestic rocket carrier into orbit. The technical and economic efficiency of the satellite system lies not only in the above advantages, but also in its hierarchical construction - combination of the root satellite, ministerial repeater, macrovers. The article provides an analysis of other low-bit satellite systems. A feature of the study of the combined LEO is the fact that the proposed construction of the satellite system allows the use of technological distributed registries as one of the through digital technologies. In digital transformation of the economy, the technology of distributed registers plays the same role as Internet things, cloud computing, 5G and Big Data technologies. The method of calculating the presented costs is to calculate the cost of the development, production and operation of the system at the stage of its design. The costs of developing space and ground segments are included in the total capital costs. The costs of developing a space segment are highlighted on the cost of developing a root satellite, a minivan-repeater, microscope. The same approach is also laid for the cost of exploitation of the space segment. When calculating the costs of the ground segment as the main component of earth stations, antenna systems, radio transmission microwaves and radio receiving microwaves, information processing devices, terminal equipment are taken as the main components of earth stations. The approximate cost of serial production of root sieuine, mini satellite, retrograder, microsatellite is indicated. The estimated cost of one minute of access in the studied combined LEO and in the existing "close" to the appointment of a low-bit satellite system is given.

In this paper, a logic selectivity system based on Long Range (LoRa) technology for the protection of medium-voltage (MV) networks is proposed. The development of relays that communicate with each other using LoRa allows for the combination of the cost-effectiveness and ease of installation of wireless networks with long-range coverage and reliability. The realized demonstrator to assess the proposed system is also presented in the paper; based on different types of faults and different locations, the times needed for clearing a fault and restoring the network were estimated from repeated experiments. The obtained results confirm that, with an optimized design of transmitted packets and of protocol characteristics, LoRa communication grants fault management that meets the criteria of logic selectivity, with fault isolation occurring within the maximum allowed time.

Piper cernuum Vell., a native species known as pariparoba, presents essential oil with potential properties and significant growth in clearings, being indicated for the recovery of degraded areas. Prospecting studies for new botanical matrices need the development of specific essays of plant propagation for future domestication of the species. This work aimed to evaluate the rooting of different types of cuttings using different substrates to develop a seedling production protocol. Stem cuttings with one or two nodes were installed on three types of substrates (medium sifted sand, vermiculite of medium granulometry and commercial substrate [Tropstrato HP®]) and maintained in greenhouse for 60 days to evaluation of the percentages of survival, mortality, sprouts, rooting, average number and average length of the roots. The results showed interaction between cutting types and substrates for rooting percentage and sprouting cuttings. The largest rooting percentages were observed in apical cuttings planted in sand and vermiculite (57.0 and 55.25%, respectively). Cuttings with two nodes presented higher performance than those with one node when compared for the analyzed variables.

Viral infections causing pandemics and chronic diseases are the main culprits implicated in devastating global clinical and socioeconomic impacts, as clearly manifested during the current COVID-19 pandemic. Immunoprophylaxis via mass immunisation with vaccines has been shown to be an efficient strategy to control such viral infections, with the successful and recently accelerated development of different types of vaccines, thanks to the advanced biotechnological techniques involved in the upstream and downstream processing of these products. However, there is still much work to be done for the improvement of efficacy and safety when it comes to the choice of delivery systems, formulations, dosage form and route of administration, which are not only crucial for immunisation effectiveness, but also for vaccine stability, dose frequency, patient convenience and logistics for mass immunisation. In this review, we discuss the main vaccine delivery systems and associated challenges, as well as the recent success in developing nanomaterials-based and advanced delivery systems to tackle these challenges. Manufacturing and regulatory requirements for the development of these systems for successful clinical and marketing authorisation were also considered. Here, we comprehensively review nanovaccines from development to clinical application, which will be relevant to vaccine developers, regulators, and clinicians.

ABSTRACTIslamic banking in Indonesia has experienced significant growth, including assets, financing providedand the number of customers. Murābaḥah is the sale and purchase of goods at the original price with theagreed-upon profit. In murābaḥah the seller must tell the cost of the product he buys and determine anadditional level of profit. This research is a library research about the murābaḥah contract according tomuamalah fiqh and its application in modern Islamic financial institutions. Methods of collecting data indocumentation and various sources related to the murābaḥah contract are then analyzed inductively anddeductively. The results of the study are the murābaḥah foundation is the principle of buying and sellingwith a deferred payment system. Murābaḥah, as used in Sharia banking, is based on two main elements,namely the purchase price and related costs, and the agreement on mark-up (profit). Islamic banks adoptmurābaḥah to provide short-term financing to customers for the purchase of goods even though thecustomer does not have the money to pay. The murābaḥah financing portfolio in Islamic banks reaches 70-80%, but in practice there have never been any problems, including; collateral which is a problem of fiqh,risk dependency as a problem of the bank, bankruptcy and delay in payment are the problems of customers,and profits are too high, namely the problem of coming from the community. Therefore, Islamic banks mustmake improvements in the implementation to be in accordance with Sharia.Keyword : Murābaḥah, Financing Instruments, Modern Islamic Financing

Lactic acid (LA) is an organic compound used in several industries, such as food, textile, chemical, and pharmaceutical. The global interest  in  this  product  is  due  to  its  use  for  the  synthesis  of  numerous  chemical  compounds,  including  polylactic  acid,  a  biode-gradable thermoplastic and substitute for petroleum-derived plastics. An in-depth overview of the use of industrial and household wastes as inexpensive substrates in order to reduce the cost of LA production is presented. A review is carried out of the biotech-nological aspects that must be taken into account when using some wastes with high transformation potential to produce LA in a submerged  culture,  as  well  recommendations  for  their  use.  The  advantages  and  disadvantages  of  different  types  of  treatments used for the transformation of waste into suitable substrates are considered. Several methods of fermentation, as well as genetic strategies for increasing the production, are summarized and compared. It is expected that in a few years there will be many ad-vances in these areas that will allow greater large-scale production of LA using agroindustrial or household wastes, with potential positive economic and environmental impact in some regions of the planet.
