Politics of the Belly
The Politics of the Belly, a translation of the French term politique du ventre, is a Cameroonian expression popularised by Jean-François Bayart in his 1989 book L'État en Afrique: La Politique du Ventre to describe African politics and, in particular, the relationship between clientelism, corruption and power. According to Lynn M. Thomas of the University of Washington:

National Liberal Club
The National Liberal Club (NLC) is a London private members' club, open to both men and women. It was established by William Ewart Gladstone in 1882 to provide club facilities for Liberal Party campaigners among the newly enlarged electorate following the Third Reform Act in 1884, and was envisioned as a more accessible version of a traditional London club. The club's Italianate building on the Embankment of the river Thames is the second-largest club-house built in London. (It was the largest ever at the time, but was superseded by the later Royal Automobile Club building completed in 1911.) Designed by Alfred Waterhouse, it was completed in 1887. Its facilities include a dining room, a bar, function rooms, a billiards room, a smoking room, a library and an outdoor riverside terrace. It is located at Whitehall Place, close to the Houses of Parliament, the Thames Embankment and Trafalgar Square.

Hydroxycinnamic Acids
Hydroxycinnamic acids (HCAs) are important natural phenolic compounds present in high concentrations in our food products. Dietary intake and nutritional importance of HCAs is briefly described along with their pharmacokinetic properties, which have a high impact on HCAs to reach the target tissue in order to exert their biological activities. A range of health beneficial effects were observed for HCAs and in recent years, also for their metabolites formed in gastrointestinal tract, liver and kidneys. Therefore, metabolism is of high importance since HCAs’ metabolites could retain, enhance or lose the biological activity of corresponding parental HCAs. The biological activities and health benefits of HCAs' metabolites are also briefly reviewed.

Triticum Dicoccum
Emmer wheat or hulled wheat is a type of awned wheat. Emmer is a tetraploid (2n = 4x = 28 chromosomes). The domesticated types are Triticum turgidum subsp. dicoccum and Triticum turgidum conv. durum. The wild plant is called Triticum turgidum subsp. dicoccoides. The principal difference between the wild and the domestic is that the ripened seed head of the wild plant shatters and scatters the seed onto the ground, while in the domesticated emmer the seed head remains intact, thus making it easier for humans to harvest the grain. Along with einkorn wheat, emmer was one of the first crops domesticated in the Near East. It was widely cultivated in the ancient world, but is now a relict crop in mountainous regions of Europe and Asia. Emmer is considered a type of farro food especially in Italy.

Shelf Life
Shelf life is the length of time that a commodity may be stored without becoming unfit for use, consumption, or sale. In other words, it might refer to whether a commodity should no longer be on a pantry shelf (unfit for use), or just no longer on a supermarket shelf (unfit for sale, but not yet unfit for use). It applies to cosmetics, foods and beverages, medical devices, medicines, explosives, pharmaceutical drugs, chemicals, tires, batteries and many other perishable items. In some regions, an advisory best before, mandatory use by or freshness date is required on packaged perishable foods. The concept of expiration date is related but legally distinct in some jurisdictions.

Salient Object Detection
Detection and localization of regions of images that attract immediate human visual attention is currently an intensive area of research in computer vision. The capability of automatic identification and segmentation of such salient image regions has immediate consequences for applications in the field of computer vision, computer graphics, and multimedia. A large number of salient object detection (SOD) methods have been devised to effectively mimic the capability of the human visual system to detect the salient regions in images. These methods can be broadly categorized into two categories based on their feature engineering mechanism: conventional or deep learning-based. In this survey, most of the influential advances in image-based SOD from both conventional as well as deep learning-based categories have been reviewed in detail. Relevant saliency modeling trends with key issues, core techniques, and the scope for future research work have been discussed in the context of difficulties often faced in salient object detection. Results are presented for various challenging cases for some large-scale public datasets. Different metrics considered for assessment of the performance of state-of-the-art salient object detection models are also covered. Some future directions for SOD are presented towards end.

Coherence
In physics, two wave sources are coherent if their frequency and waveform are identical. Coherence is an ideal property of waves that enables stationary (i.e. temporally or spatially constant) interference. It contains several distinct concepts, which are limiting cases that never quite occur in reality but allow an understanding of the physics of waves, and has become a very important concept in quantum physics. More generally, coherence describes all properties of the correlation between physical quantities of a single wave, or between several waves or wave packets. Interference is the addition, in the mathematical sense, of wave functions. A single wave can interfere with itself, but this is still an addition of two waves (see Young's slits experiment). Constructive or destructive interference are limit cases, and two waves always interfere, even if the result of the addition is complicated or not remarkable. When interfering, two waves can add together to create a wave of greater amplitude than either one (constructive interference) or subtract from each other to create a wave of lesser amplitude than either one (destructive interference), depending on their relative phase. Two waves are said to be coherent if they have a constant relative phase. The amount of coherence can readily be measured by the interference visibility, which looks at the size of the interference fringes relative to the input waves (as the phase offset is varied); a precise mathematical definition of the degree of coherence is given by means of correlation functions. Spatial coherence describes the correlation (or predictable relationship) between waves at different points in space, either lateral or longitudinal. Temporal coherence describes the correlation between waves observed at different moments in time. Both are observed in the Michelson–Morley experiment and Young's interference experiment. Once the fringes are obtained in the Michelson interferometer, when one of the mirrors is moved away gradually from the beam-splitter, the time for the beam to travel increases and the fringes become dull and finally disappear, showing temporal coherence. Similarly, in a double-slit experiment, if the space between the two slits is increased, the coherence dies gradually and finally the fringes disappear, showing spatial coherence. In both cases, the fringe amplitude slowly disappears, as the path difference increases past the coherence length.

Theory of Planned Behavior in Energy-Saving Behaviors
People with physical impairments can help solve energy problems by participating in diverse energy-saving behaviors, such as switching off lights or turning off an air conditioner when not in use; however, they may struggle to participate in some behaviors due to mobility impairments. An energy-saving behavior is an individual action that aims to reduce energy consumption and the negative environmental impacts of energy consumption and production. The theory of planned behavior (TPB), which was proposed by Ajzen in 1985, is an extension of the theory of reasoned action (TRA).

Moringa as Natural Feed Supplement
Application of natural herbs with a view to enhancing production performance and health status has created an important demand in poultry production. With the increasing concerns on this issue, greater attention paid to alternatives to antibiotics for organic meat and egg production has led to a great demand. This study was conducted with view to assessing the possible role of M. oleifera as a natural feed supplement in poultry ration. Various scientific findings and published research articles were considered concerning issues including the study background, objectives, major findings, and conclusions of the review. M oleifera is known as a miracle tree because of its wealthy resource of various nutrients with high biological values. M. oleifera has been used as a growth promoter, immune enhancer, antioxidant, and has a hypo-cholesterol e ect on chickens. It has both nutritional and therapeutic values. However, there is still much confusion in past published articles involving the major roles of M. oleifera in production performance and health status of chickens. Taking this into account, the present study highlights an outline of the experimental uses of M. oleifera on growth performance, egg production performance, egg quality, and health status in broilers and laying hens justified with the past findings to the present. The knowledge gaps from the past studies are considered, and the feasibility of M. oleifera in poultry ration is suggested. The findings have motivated further study on M. oleifera to find out the most active ingredients and their optimal doses in both broiler and laying hen rations. Finally, the present study highlights that supplementation of M. oleifera may play a role in the immunity, sound health, and production performance in poultry.

Relationships of Environmental Economics and Sustainable Development Goals
Environmental issues have increased, whereas the Earth’s natural resources have deteriorated. These problems have forced people and companies to engage in environmental economics to achieve sustainability. However, several barriers have been identified in the implementation of environmental economics. It is proven that environmental economics has many benefits in preventing environmental problems and achieving sustainability. This economic concept also correlates with the majority of the goals of sustainable development programs, assisting many countries in achieving these objectives. There are four strategies identified that are the most utilized: The inclusion of natural capital in the System of National Accounts (SEEA), green consumerism, fiscal policy, and de-growth economic model. The SEEA is correlated with sustainable development goals (SDGs) 1 (No Poverty), 3 (Good Health and Well-being), 6 (Clean Water and Sanitation), 14 (Life below Water), and 15 (Life on Land). Green consumerism aligns with SDGs 3 (Good Health and Well-being), 12 (Responsible Consumption and Production), and 13 (Climate Action). Fiscal policy is correlated with the SDGs 1 (No Poverty), 3 (Good Health and Well-being), 13 (Climate Change), 12 (Responsible Consumption and Production), 14 (Life below Water), and 15 (Life on Land). Lastly, the de-growth economic model aligns with SDGs 1 (No Poverty), 7 (Affordable and Clean Energy), 9 (Industry, Innovation, and Infrastructure), 11 (Sustainable Cities and Communities), 12 (Responsible Consumption and Production), and 13 (Climate Action).
