Abstract:

The liquefied natural gas (LNG) fuel tank in a large container ship is loaded with liquid LNG at an ultra-low temperature (-163°C), there is a significant temperature difference in the cargo hold area where the entire fuel tank is located, which will have an important impact on the steel grade design and structural safety of the cargo tank in container ship. This paper develops two heat transfer models using Computational Fluid Dynamics method (CFD method) and an analytical method to analyze the temperature distribution in a large container ship equipped with Type-B LNG fuel tank. These models

Abstract:

Vertical cylindrical tanks for bulk storage of oil and liquefied gas are sometimes constructed on soils that are susceptible to settlement. The types of foundation settlement and their structural effects on the tank are reviewed. An arbitrary operational limit of 1 in 200 is sometimes quoted for the foundation tilt of atmospheric storage tanks. This limit is based on aesthetic considerations and on the effects on pipework connections and other attachments. Many tanks reach this limit before the end of their design life, and tank owners face difficulties in assessing the effects of foundation t

Abstract:

Abstract In the absence of external heat exchangers, the on-orbit transfer of cryogenic propellants requires the receiver tank to first be quenched to a sufficiently low energy state to allow for a continuous no-vent fill to avoid unnecessary venting of liquid. One proposed method for tank chilldown that minimizes the potential for venting liquid is the charge hold vent (CHV) method. CHV follows a cyclic process that gradually removes thermal energy from the receiver tank by injecting liquid with the vent valve closed and allowing the fluid and wall to reach near-thermal equilibrium before ven

The characteristic frequency was also determined, which corresponds to about twice the oscillation frequency. Model gas hold-up values for coalesc

Abstract:

Introduction. Vertical steel tanks are extensively used in oil fields to hold crude oil and other liquids. Their construction requires continuous surveying control. However, measurement procedures, data processing, and deviations and documentation correction are not universal and cannot be applied for tanks with a capacity of less than 3000 m3. Moreover, the process of correcting the detected bottom irregularities is poorly substantiated and intuitive. Research objective is to improve the as-built survey accuracy and reliability of the low-capacity steel tank bottom, substantiate the minimum h

The object of research is the process of inerting the cargo tank of an oil tanker. Issues related to improving the process of preparing cargo tanks of oil tankers for cargo operations are considered. It is noted that the efficiency of oil tanker operation, in addition to transport operations, is determined by the technologies used during the preparation of the vessel for receiving new cargo. One of such technologies is the inerting cargo tanks, which precedes any cargo operations. The study was aimed at improving the inert flue gas system by using a new technology for supplying jets of inert g

Abstract:

Think tanks, or policy advice institutions, are civil society organizations producing and delivering social analysis to policymakers and the wider public. Their aim is to influence policy in a given direction. Compared to most other civil society organizations, they hold relatively privileged positions, both in terms of wealth (on average bigger budgets and staffs), political influence (their very raison d’être), knowledge (educational level of the staff), and social networks. Thus, it seems beyond dispute that think tanks adhere to the elite of civil society. This article focuses on think tan

The demand for liquefied natural gas (LNG) ships is increasing for various reasons.

A pivotal aspect of the project involved developing a prototype research installation for conducting comprehensive testing. Our installation system consisted of several compo

Abstract:

The basal fermentation time and hydraulic retention time were systemically investigated about anaerobic fermentation production hydrogen process by continuous flow which is based on activated sludge for a basic strain and simulating sucrose wastewater for a substrate in a continuous stirred tank reactor. The highest hydrogen production rate was got at the fermentation time of 15h for and 6h for hydraulic retention time. The optimum run acidity (pH = 4.5 5.0) was kept through their own system circulation to hold the system state of high-speed and continuous hydrogen production. The results can

Abstract: Due to the rise in population and increase in urbanisation levels in our country, most of the settlements are in urban areas. As the cities that already existing are heavily populated along with a great deal of limitations in the infrastructure, emergence of an advanced township away from the vicinity of these overpopulated urban areas offer safer and better accommodation for the people. The planning and layout of the project is shown using autoCAD and for the structural analysis we use STADD Pro V.18i. Demographic analysis is done among specific clientele.

Abstract:

The design of an aquaponics system is a major drive in achieving a sustainable agricultural practice, tackling environmental problems, and food security. Aquaponics provides a conservative technique that integrates both hydroponics and aquaculture in regions with minimal arable land. This current study aims to design and build an aquaponics system that is suitable and beneficial to its environment. The objectives of building the aquaponics system are to cultivate fish and plants in a closed system that can reduce the requirement for chemical-based nutrients and increase water-use efficiency. P

Abstract:

Abstract This article explores the phenomenon of foreign policy think tanks in Europe in a comparative perspective and offers a framework of analysis for this topic. Assuming that think tanks were largely imported from the US after World Wars I and II, the article argues that European think tanks have been influenced by the different national political contexts in which they have undergone a process of institutionalization. First, the article hypothesizes that such contexts have contributed to determining different incentives for cooperation between think tanks and national policymakers. Such

Abstract:

Biological excretion from patients (urine) generated during radionuclide diagnostics enters directly into the hospital sewage system. The establishment of new clearance level according to Resolution of the Government of the Russian Federation No. 1069 of October 19, 2012 may entail amendments to regulatory documents for radionuclide diagnostics departments. One of these requirements is a mandatory dedicated sewage system. Establishment of the requirement may lead to an increase the cost of the radionuclide diagnostic examinations, and to a decrease the accessibility of radionuclide diagnostic.

Abstract:

Vertical greenery systems (VGS) are effective at solving urban heat. They can absorb noise pollution and dust, and, aesthetically, they are positively perceived. Systems using hydroponic irrigation and nutrition, in combination with mineral wool as a base, are light and effective (they are able to hold water, with a high percentage of air, and a good mechanical structure to hold the plant stable). However, the functionality of a system can be compromised if the water supply is depleted or the irrigation system fails. This deficiency can be partially remedied if a certain amount of biochar or a

The article reveals the characteristics of think tanks as actors of the interest group politics in the European Union (EU). In this policy, they inspire public debate, conduct research, encourage new legislation and more effective public administration. A large number of European think tanks is engaged in interest group politics both at the national and supranational level of the EU governance, encouraging integration processes among the EU countries and Europeanization, which is the subject of analysis of this study.

Abstract:

In this paper the phenomenon of inverse response from systems was investigated and its transient response thoroughly analyzed. Inverse response is shown by non-minimum phase systems and some minimum phase systems. Transient analysis of these systems is lacking in literature A case study was done for a non-linear, non-minimum phase CSTR (Continuous Stirred Tank Reactor), which was identified. Different control schemes were also implemented on other systems as well, which exibhit inverse responses, including model reference adaptive control. The finding shows that PID goes with the inverse respo
