CO2 Separation Techniques
Energy plants, industries, as well as other sources of carbon dioxide (CO2) result in global warming and affect the planet. CO2 is separated from flue gas during combustion using a variety of advanced separation techniques. There are several techniques involved, such as absorption, adsorption, chemical looping, membrane separation, and cryogenics.

Synthesis of Fragrances via Cycloaddition or Formal Cycloaddition
Fragrances, short for fragrance ingredients, is a type of compounds with a sweet smell or pleasant odor that has wide applications in the fine chemical industry, especially in perfumes, cosmetics, detergents and food additives. Since the discovery of the Diels–Alder reaction, the cycloaddition of π reactants serves as one of the most powerful methods for the construction of carbocycles, which has a broad application in the fragrance industry.

Hypocrisy
Hypocrisy is the contrivance of a false appearance of virtue or goodness, while concealing real character or inclinations, especially with respect to religious and moral beliefs; hence, in a general sense, hypocrisy may involve dissimulation, pretense, or a sham. Hypocrisy is the practice of engaging in the same behavior or activity for which one criticizes another. In moral psychology, it is the failure to follow one's own expressed moral rules and principles. According to British political philosopher David Runciman, "Other kinds of hypocritical deception include claims to knowledge that one lacks, claims to a consistency that one cannot sustain, claims to a loyalty that one does not possess, claims to an identity that one does not hold". American political journalist Michael Gerson says that political hypocrisy is "the conscious use of a mask to fool the public and gain political benefit". Hypocrisy has been a subject of folk wisdom and wisdom literature from the beginnings of human history. Increasingly, since the 1980s, it has also become central to studies in behavioral economics, cognitive science, cultural psychology, decision making, ethics, evolutionary psychology, moral psychology, political sociology, positive psychology, social psychology, and sociological social psychology.

Sub Synchronous Oscillation Phenomenon
The definition of sub synchronous oscillation (SSO) according to the IEEE Sub Synchronous Resonance Working Group is as follows. “Sub synchronous oscillation is an electric power system condition where the electric network exchanges significant energy with a turbine generator at one or more of the natural frequencies of the combined system below the synchronous frequency of the system following a disturbance from equilibrium”. According to the classification of SSO by the IEEE Sub Synchronous Resonance Working Group, there are two types of SSO, namely sub synchronous resonance (SSR) and device dependent sub synchronous oscillation (DDSSO). Sub synchronous control interaction (SSCI) and sub synchronous torsional interaction (SSTI) are other types of SSO. However, they are not included in the formal classification.

Low Intensity Conflict
A low-intensity conflict (LIC) is a military conflict, usually localised, between two or more state or non-state groups which is below the intensity of conventional war. It involves the state's use of military forces applied selectively and with restraint to enforce compliance with its policies or objectives. The term can be used to describe conflicts where at least one or both of the opposing parties operate along such lines.

Different Types of Adipocytes
Adipose tissue resides in specific depots scattered in peripheral or deeper locations all over the body and it enwraps most of the organs. This tissue is always in a dynamic evolution as it must adapt to the metabolic demand and constraints. It exhibits also endocrine functions important to regulate energy homeostasis. This complex organ is composed of depots able to produce opposite functions to monitor energy: the so called white adipose tissue acts to store energy as triglycerides preventing ectopic fat deposition while the brown adipose depots dissipate it. It is composed of many cell types. Different types of adipocytes constitute the mature cells specialized to store or burn energy. Immature adipose progenitors (AP) presenting stem cells properties contribute not only to the maintenance but also to the expansion of this tissue as observed in overweight or obese individuals.
