I Når Vi Rejser Til Mars møder vi journalisten Laura, der har trukket stikket fra den bekvemmelige og moderne tilværelse i byen og i stedet er flyttet ud i et forfaldent hus uden strøm i de skånske skove. Laura prøver ihærdigt at få sin økonomi til at hænge bedre sammen ved at skrive en økokritisk artikelserie, synkront med at hun forsøger at genfinde roen i skovens uberørte steder. Men allermest ønsker Laura at skabe den bedste opvækst for datteren Bea, en opvækst tæt på naturen. Problemet er at ingenting hun gør, ser ud til at virke: ”Laura troede det gik op her. Hun troede, det ville være godt for Bea at komme til noget lidt mere civiliseret, da hun skulle begynde i skole. Hun tog fejl. Bea har det overhovedet ikke godt. Man kan heldigvis fortryde. Vende om. Vende tilbage.”Når Vi Rejser Til Mars er en samtidsroman, der skildrer flere af nutidens største problematikker, både fra det store kollektive synspunkt; hvad fremtiden vil bringe os som menneskehed, hvis klimakrisens konsekvenser forsætter i sin nedadgående spiral, der i sidste ende vil betyde Jordens endelige undergang. Men samtidigt er det også en roman, der fremstiller menneskets ældste urinstink i moderne rammer; forholdet mellem mor og barn, og den uudtalte problematik når det forventede relationsglansbillede ikke stemmer overens med virkelighedens, når gode intentioner ikke altid er nok, når man skal skabe en lykkelig tilværelse for ens barn og en selv.Maja Elverkilde debuterede som forfatter i 2008 med den anmelderroste novellesamling Alt det der er mit. I 2011 blev hun selv mor og skiftede kort tid efter sin lejlighed i København ud med et primitivt hus i Sverige, hvor hun boede alene med sin dreng. I 2014 udkom opfølgeren Det man dør af og i 2017 kom romandebuten Den slags skal gøres i dagslys. Når Vi Rejser Til Mars er Elverkildes første udgivelse på Forlaget Escho.

In the modern world, travel and commerce within the aviation industry are major drivers of global economic growth. Nonetheless, a number of barriers stand in the way of the aviation industry's continued expansion and viability. The largest of these issues is the fuel usage in aircraft. An increase in fuel consumption results in a rise in operating costs and anthropogenic emissions.In order to evaluate aviation fuel consumption criteria, the author's goal in this book is to evolve, conceptualize, and develop a reliable Reduction in Aviation Fuel Consumption (RAFC) model.A thorough assessment of the literature served as the foundation for the development and conceptualization of the RAFC framework. Therefore, this book examined a mix of qualitative and quantitative methods to implement the methodology with primary and secondary data. It carried out analysis utilizing a variety of techniques, including regression analysis, factor analysis, structural equation modeling, and AHP-entropy. This combination guaranteed the study's adaptability, economy, and consistency. Future interest in minimizing fuel consumption and emissions and maximizing revenue under prevailing social, economic, political, environmental, and other restrictions might be stoked by knowledge of RAFC correlations with factors and sub-factors. Consequently, it will lead aviation toward a future that is both ecologically friendly and fuel-efficient. This book is a vital resource for academics, researchers, engineers, airline personnel, and decision-makers (governments and regulatory organizations) as it offers a thorough framework that gives an overall view of the aviation industry with regard to fuel usage.

This book showcases Nigerian and South African experiences on space politics, policy and strategy vis-à-vis their development and security aspirations, while contributing to the broader African and the Global-South perspectives on the subject. Space policy in developing countries such as Nigeria and South Africa is motivated by utilitarian promises that space and the attendant technologies have the potential to advance development and security interests of the affected nations. However, several decades into the orbital journey of these countries, little is known of their space politics, policies, strategies, capacities and capabilities, and realisation of desired objectives. Beyond pure and applied sciences reductionism, this book offers social science perspectives on space studies in Africa, as it examines the intricate relationships of historical, geographical, social, demographic, economic, political, administrative, and strategic factors, nationally, regionally and globally thathave shaped research and development of space science and technologies, and their benefits, in Nigeria and South Africa.

This study assumes Space Elevators can and must be built. "Space Elevators: The Green Road to Space," completed in April 2021, emphasizes that Space Elevators will not replace rockets but would join them on parallel paths towards the stars. This Dual Space Access Strategy will carry out the missions that are now planned and ensure the future we dream of becomes a reality. Space Elevators are needed to do the "heavy lifting" for movement off planet. Their transformational characteristics will enable so many of humanity's dreams by moving huge mass to far away destinations.Space Elevator Vision: Space Elevators are the Green Road to Space while they enable humanity's most important missions by moving massive tonnage to GEO and beyond. They accomplish this safely, routinely, inexpensively, efficiently, daily and they are environmentally neutral.

This book is a useful source of knowledge for engineers and scientists in the field of mechanics of deformation and destruction of composite materials.In Chapter 1 three-dimensional equations of elasticity theory composed for the case of finite displacements and deformations of solids have been analyzed. It is found that the generally accepted simplifications known in the literature and carried out for the case of small deformations result in equations that are considered to be absolutely correct and consistent in all scientific and educational literature on mechanics of deformable solid bodies. However, this conclusion is not sufficiently well-founded as confirmed by formulation and solution of problems on the basis of generally accepted equations for determining both the stress-strain state (SSS) and the critical loads and buckling modes. In Chapter 2 the theoretical and experimental methods for determining the mechanical characteristics of fiber-reinforced plastics (FRPs) based on tensile and compression tests of flat specimens with [0]s , [±90]s, and [±45]2s lay-ups are analyzed. For FRPs with [±45]2s lay-ups, relations are derived for determining the components of lamina strains and stresses in the orthotropy axes of FRP monolayer in terms of axial strains and Poisson ratios of specimens measured in experiments. In Chapter 3 the structure of a unidirectional fibre composite of two types ELUR-P carbon fibre based on KhT-118 cold-curing binder and HSE 180 REM prepreg based on hot-curing binder has been studied. The diameters of fibres and fibre bundles (filaments) of both types of composites have been measured. Based on the results of the analysis of the composite material structure, a refined formulation of the linearised problems of a refined statement of linearized problems on flat internal multiscale buckling modes of a rigid lamina with either fibers or a fiber bundle is presented taking into account their interaction with an epoxy matrix. In Chapter 4 for shells of a layered structure based on the Timoshenkös model, taking into account the transverse compression used for each layer, two versions of two-dimensional equations are constructed that describe geometrically nonlinear deformation with arbitrary displacements and small deformations. The formulation of a linear problem on the initial (subcritical) stress-strain state of a test specimen from a unidirectional fibrous composite with the [900]s structure during tension-compression tests with shear is given. A numerical method for solving the formulated problem is developed, which is based on the reduction of the original problem to a system of integro-algebraic equations and the search for their numerical solution by the finite sum method. In Chapter 5 conclusions were done and directions for further research have been identified.
