The Concept of Floating Shipyard

Shipyards are known as a land-based facility that ships steer to for docking and repair. This study represents an introductory conceptual study for a new principle of developing a Floating shipyard: changing the phenomena of a fixed site shipyard into a self-propelled floating shipyard. This Floating Shipyard can travel and conduct dry-docking activities at the client's location or even lift the client's vessel and travel to the F-Yard extension, taking advantage of having comprehensive repair or conversion. The arising challenges to this floating shipyard, such as lay-offs, restructuring, and environmental legislation, requires a balanced solution. The solution of all this relies on adapting talent management and competitive production tools during this massive undergoing change in its backbone structure. The Floating shipyard, here named "F-Yard", changes the mindset of dry-dock. This is because F-Yard travels to the client's location or is capable of pick the client's unit nearby the cargo destination, where it can complete the required dry-dock or repair. The cutthroat advantage of the F-Yard comes from self-propelled, where the other approaches depend on others for mobilizing and anchoring from one location to another. In addition, F-Yard could serve other industries, due to its fully equipped workshops, that able to serve different market needs such as oil and gas and renewable energy...etc. These open the door for a variety of business scope. F-Yard depends on front-end engineering and marketing teams to optimize its route and sort the supply chain requirements.

Analysis and Design of a Silicide-Tetrahedrite Thermoelectric Generator Concept Suitable for Large-Scale Industrial Waste Heat Recovery

Industrial Waste Heat Recovery (IWHR) is one of the areas with strong potential for energy efficiency and emissions reductions in industry. Thermoelectric (TE) generators (TEGs) are among the few technologies that are intrinsically modular and can convert heat directly into electricity without moving parts, so they are nearly maintenance-free and can work unattended for long periods of time. However, most existing TEGs are only suitable for small-scale niche applications because they typically display a cost per unit power and a conversion efficiency that is not competitive with competing technologies, and they also tend to rely on rare and/or toxic materials. Moreover, their geometric configuration, manufacturing methods and heat exchangers are often not suitable for large-scale applications. The present analysis aims to tackle several of these challenges. A module incorporating constructive solutions suitable for upscaling, namely, using larger than usual TE elements (up to 24 mm in diameter) made from affordable p-tetrahedrite and n-magnesium silicide materials, was assessed with a multiphysics tool for conditions typical of IWHR. Geometric configurations optimized for efficiency, power per pair and power density, as well as an efficiency/power balanced solution, were extracted from these simulations. A balanced solution provided 0.62 kWe/m2 with a 3.9% efficiency. Good prospects for large-scale IWHR with TEGs are anticipated if these figures could be replicated in a real-world application and implemented with constructive solutions suitable for large-scale systems.

Vancomycin Adsorption During in vitro Model of Hemoperfusion with HA380 Cartridge

<b><i>Introduction:</i></b> A critical point for using blood purification during sepsis may be the potential interaction with antimicrobial therapy, the mainstay of sepsis treatment. The aim of our study was to investigate the vancomycin removal during hemoperfusion (HP) using HA380 cartridge. <b><i>Methods:</i></b> This is an experimental study, in which 500 mL of solution was circulated in a closed-circuit (blood flow of 250 mL/min) simulating HP ran using HA380. Vancomycin was added to reach a through concentration or a very high concentration to evaluate the removal ratio (RR) during 120 min of HP. Comparison between blood-crystalloid solution and balanced solution was performed by using Kruskal-Wallis test. The kinetics of vancomycin removal and the adsorption isotherm were evaluated. <b><i>Results:</i></b> We found a complete removal of vancomycin at baseline through concentration of 23.0 ± 7.4 mg/L. Using extremely high concentration (baseline 777.0 ± 62.2 mg/L), RR was 90.1 ± 0.6% at 5 min and 99.2 ± 0.6% at 120 min. No difference in terms of RR was found between blood-crystalloid mixture and balanced solution. The kinetics of the vancomycin reduction followed an exponential decay. Repeated boluses (total amount of 2,000 mg) resulted in cumulative adsorption of 1,919.4 mg with RR of 96.6 ± 1.4%, regardless of the amount injected (100 vs. 500 mg). Vancomycin adsorption onto HA380 followed the Langmuir isotherm model. <b><i>Conclusions:</i></b> A considerable amount of vancomycin was rapidly removed during in vitro HP with HA380. Clinical studies are needed to determine whether this may lead to underdosing. Drug therapeutic monitoring is highly recommended when using HA380 for blood purification in patients receiving vancomycin.

Floating Shipyard: Drydock during the ship’s voyage

Shipyards are known as a land-based facility that ships steer to for docking and repair.

Investment attractiveness of enterprise and sustainable development of industrial region

In accordance with the Russian Federation consistent transition to sustainable development, which material basis consists in not so much quantitative but rather qualitative transformations in the factors of real economy production, the authors hereby focus on the regional aspect of territorial entity environments affecting favorably the investment attractiveness of industrial enterprises. Special attention is paid to the fact that following the sustainable development paradigm implies a balanced solution of economic, social and environmental problems. The conceptual considerations presented are taken as the basis for an original universal method to diagnose and assess restrictions, threats, and challenges of an economic, administrative and legal, resource and technical, social and environmental nature that occur at the regional level and affect the investment attractiveness of enterprises. In practice, the approach considers the diagnostics possibility to develop, firstly, specific measures to offset or reduce the negative impacts determining the investment attractiveness of regional investment objects and, secondly, motivational and stimulating measures to resolve the conflicts arising due to environmental and social restrictions on economic activity in order to ensure, as we move towards sustainable development, a balanced solution to three tasks: ensuring economic growth, achieving social progress, and improving the quality of the environment.

A Reason and a Spirit: Body without Organs

This article is devoted to possible types of organization of global AI and possi­ble measures to counter the loss of autonomy by individuals – their transforma­tion into HomoCell – human cells of a more global organism. The text of Im­manuel Kant What is Enlightenment? Was chosen as a guideline. The author emphasizes that as the goal of the Enlightenment, Kant sets the task – the acqui­sition of independence by individuals in the use of their own mind. The afore­mentioned work remains one of the main programmatic texts of the Enlighten­ment, which, according to the author, is not over yet. The article notes that an autonomous or independent individual is an exclusion from society, literally. However, the connection of such subjectivization with marginality introduces the binary opposition norm/abnormality. The idea is that this dichotomy creates two opposing areas in the field of culture, thus making it impossible to either indicate or think over a balanced solution to the problem posed by Kant. The author proposes to trace the genealogy of the development and addition of the concept of Cogito – from Descartes to Deleuze – as the basis for the interpreta­tion of the subject, to introduce it into the theory of systems, and, thereby, rised above oppositions.

Economic and legal factors of investment in subsoil use in the aspect of implementation sustainable development concepts

Following the paradigm of sustainable development presupposes a balanced solution of three tasks: ensuring economic growth, achieving social progress and improving the quality of the environment. However, the solution of environmental and social problems causes restrictions on economic activities. In this regard, there is a need to develop methodological approaches to the formation of organizational and economic relations and mechanisms in order, firstly, to resolve the contradictions between the economic and socio-environmental, and, secondly, to provide motivation to activate investment processes in a direction conducive to achieving goals of sustainable development of subsoil use. The problem of investment attractiveness becomes even more urgent, taking into account the special nature of industrial relations developing in subsoil use, which must be taken into account when implementing the concept of sustainable development.

Global Stability and Dynamic Analysis for a Type of Macroeconomic Systems

This paper aims at the dynamic properties of the proposed globally planned economic systems named after CPE proposed by Loo-Keng Hua who is one of the worldwide famous Chinese mathematicians. First, we give new existence conditions of growth balanced solution to the model. Second, we lead into the concept of stability for balanced output and carry out a theorem that deals with some equivalent conditions for judging a solution of output starting from the fact that any initial input can whether approach the existing balanced solution or not. Third, a new dynamic price system related to interest factors is proposed here and it is demonstrated that the new price equation is a much generalized one in comparison with the original price one which is only a special case of this new price equation. Also, relationships of the balanced solutions between the price and the output equation are investigated and the stability analysis is studied as well for the new price system. Finally, two examples are employed to illustrate the technical operation of input-output method and some new contributions of this article.

Calibration of the design of cholesterol in order to balance the light of the day with the thermal performance in order to raise the sustainability of university buildings in Syria: معايرة تصميم الكوليسترات من أجل موازنة ضوء النهاري مع الأداء الحراري في سبيل رفع استدامة المباني الجامعية في سوريا

In a fully glazed building façade with solar inhibitors with holes (cholesters) (PSS), it is often used as an exterior casing in order to reduce energy consumption and solve other problems such as: transparency of vision. Moreover, the function of these cholesteres is not only to control the solar inhibitors entering the building, but also to control the provision of appropriate degrees of daylight, and thus we have created a balanced solution to the daytime lighting process. Nowadays, daylight simulation software applications enable us to apply scientific analyzes of daytime management in a vacuum when using cholesters (PSs). Regardless of that, current applications of sun simulation (such as: EnergyPlus) cannot deal with some engineering configurations directly, making the process of estimating the thermal factor of solar inhibitors with holes is not possible. This research provides a scientific method to achieve integrated analyzes of daytime lighting and energy consumption of voids using cholesteres during the design process on local university buildings, and such a scientific method provides us with daylight analyzes through (DIVA) and also provides thermal analyzes via EnergyPlus with DIVA / GRASSHOPPER / ARCHSIM The goal is to control the double performance of cholesters by controlling the intensity, arrangement, and shape of these perforations using the statistical method of vertical beams (DOA), and studying the simultaneous gain of daylight and the thermal efficacy of cholesters in order to provide an annual balanced and integrated solution. The (DOA) method is effective in reducing the number of simulations drawn from a mixture of the aforementioned variables and identifying the visual arrangements of these fluids. In comparison with an imperfect interface for a building located in the buildings of the University of Aleppo in Aleppo, these solar fluids with holes achieve an expectation of a decrease .The areas that are actually illuminated by daylight are (50%) and 55% less energy is needed in the building. Although this work uses the DOA method to improve the three design variables, it is possible in the future to increase these factors to include the thickness of the panels, the materials made from them and the slope of the panels.
