The majority of the world’s largest carbon emitters are either federations or have adopted systems of decentralised governance. The realization of the world’s climate mitigation objectives, therefore, depends in large part on whether and how governments within federal systems can cooperate to reduce carbon emissions and catalyze the emergence of low-carbon soci…
Exactly 100 years ago prof. Joukowsky, one of the founders of modern aerodynamics, published the first rotor performance prediction. The tools of Jankowsky and his contemporaries were mathematics and wind tunnel experiments, nowadays we use mathematics, numerics, full scale experiments and, still, wind tunnel experiments.
The most important fact related with fluid motion is to understand the fluid patterns, and the flow structure †vortices, recirculation zones, high mix regions, poor mix regions, calm regions, to name a few. Moreover, most of the flows have turbulent characteristics and turbulence remains one of the unsolved problems in physics.
Climate Change 2022: Mitigation of Climate Change is the third part of the Sixth Assessment Report (AR6) of the Intergovernmental Panel on Climate Change (IPCC) and was prepared by its Working Group III. The volume provides an updated global assessment of current and projected emissions from all sources and sectors, mitigation options that reduce emissions or remove greenhouse gases from the a…
Physical theories, while devised to model a particular range of phenomena, are evidently linked in a hierarchical fashion. It is this structure which keeps fascinating me. In statistical mechanics, my scientific home-town, the link between atomic and macroscopic properties is one central issue. There we are taught that the emergence of a more restricted theory from a more general one has a rich…
Quantum field theory, our description of the fundamental forces in nature, was originally formulated in continuous space–time, where it leads to embarrassing infinities which have to be eliminated by a process called renormalization. A simple but rigorous formulation can be obtained by replacing continuous space–time by a discrete set of points on a lattice. T…
Beyond being the most important natural compound source, actinomycetes are the origin of up to two-thirds of all clinically used antibiotics. Currently, new antimicrobials are urgently needed, as infections caused by antibiotic-resistant pathogens are on the rise. In the identification of new antibiotics, many scientists are currently investigating biosynthetic aspects of antibiotic production …
This book is a collection of fundamental and applied research on the plant root response to environmental clues. In particular, the continued adaptation of both fine and coarse roots to modifications due to natural and anthropogenic causes were investigated from different viewpoints. Additionally, specific root traits were investigated as an optimal indicator of responses to the environment at …
Infrastructure development in Africa and Asia is expanding at breakneck speed, largely in biodiversity-rich developing nations. The trend reflects governments’ efforts to promote economic growth in response to increasing populations, rising consumption rates and per￾sistent inequalities
Antimicrobial resistance is the intrinsic capability of microorganisms to survive unfavorable conditions; such traits are mainly transferrable through movable genetic elements, enabling the rapid and homogeneous diffusion of resistance genes over diverse ecosystems and sectors including human medicine, veterinary medicine, and the environment. In this view, the One Health approach allows for a …
