Local Chicken Breeds and Varieties
Conservation of local breeds possessing genetic variations specific to the particular environment is essential for sustainable development. Although they exist as numerically small populations, local breeds are not only highly adapted to the natural environment, but are also an integral part of the lifestyle of the rural people. People, livestock and environment form a delicately balanced but sustainable ecosystem, and thus the potential impact of any intervention to improve production in the traditional system should be predetermined. The situation is less sensitive in periurban, industrial and small-scale intensive poultry production, in which rapid improvements can be achieved through well-designed development programmes. The intensive poultry production sector, however, is generally much smaller than the family poultry sector in virtually all developing countries. The present review evaluates twenty years (2001 to 2021) of the study of growth and performance in local chicken breeds worldwide. The assessment of methodological approaches and their constraints when intending to fit for data derived from often endangered autochthonous populations was performed. The evaluation of conditioning factors on the impact that publications reporting on research progresses in the field have on the scientific community and how such advances are valued suggests the need to seek new methodological alternatives or statistical strategies. Such strategies must meet the requirements of local populations which are characterized by reduced censuses, a lack of data structure, highly skewed sex ratios, and a large interbreed and variety variability. The sustainable conservation of these populations cannot be approached if scientific knowledge on their productive behaviour is not reinforced in a manner that allows distinctive products to be put on the market and be competitive.

Demand Chain Management
Demand chain management (DCM) is the management of relationships between suppliers and customers to deliver the best value to the customer at the least cost to the demand chain as a whole. Demand chain management is similar to supply chain management but with special regard to the customers. Demand chain management software tools bridge the gap between the customer relationship management and the supply chain management. The organization's supply chain processes are managed to deliver best value according to the demand of the customers. DCM creates strategic assets for the firm in terms of the overall value creation as it enables the firm to implement and integrate marketing and supply chain management (SCM) strategies that improve its overall performance. A study of the university in Wageningen (the Netherlands) sees DCM as an extension of supply chain management, due to its incorporation of the market orientation perspective on its concept.

The Emergence of Organoids in Cellular Systems
Cellular models have created opportunities to explore the characteristics of human diseases through well-established protocols, while avoiding the ethical restrictions associated with post-mortem studies and the costs associated with researching animal models. Organoids are 3D cellular structures that mimic the architecture and function of native tissues. They are generated in vitro from stem cells or differentiated cells, such as epithelial or neural cells, and are used to study organ development, disease modeling, and drug discovery. Organoids have become a powerful tool for understanding the cellular and molecular mechanisms underlying human physiology, providing new insights into the pathogenesis of cancer, metabolic diseases, and brain disorders.

Cell Sources for Retinal Regeneration
The main degenerative diseases of the retina include macular degeneration, proliferative vitreoretinopathy, retinitis pigmentosa, and glaucoma. Novel approaches for treating retinal diseases are based on cell replacement therapy using a variety of exogenous stem cells. An alternative and complementary approach is the potential use of retinal regeneration cell sources (RRCSs) containing retinal pigment epithelium, ciliary body, Müller glia, and retinal ciliary region. RRCSs in lower vertebrates in vivo and in mammals mostly in vitro are able to proliferate and exhibit gene expression and epigenetic characteristics typical for neural/retinal cell progenitors.

July 1: Adoption of SOS as the International Distress Signal
SOS is a standardized Morse code distress signal consisting of three short dots, three long dashes, and three short dots (· · · — — — · · ·). Contrary to widespread misconception, the sequence is not an acronym for “Save Our Ship” or “Save Our Souls,” but was selected for its simplicity, rhythmic clarity, and high recognizability in radio transmission. On July 1, 1908, it was formally adopted as the international maritime distress signal, replacing a variety of competing calls and marking a milestone in the regulation of wireless telegraphy.

Sweetness Perception of Food/Beverages
When it comes to eating and drinking, multiple factors from diverse sensory modalities have been shown to influence multisensory flavour perception and liking. These factors have heretofore been strictly divided into either those that are intrinsic to the food itself (e.g., food colour, aroma, texture), or those that are extrinsic to it (e.g., related to the packaging, receptacle or external environment).

Quantum Dots for Optoelectronic Applications
Quantum dots (QDs) are tiny semiconductor particles that typically range in size from 2 to 10 nanometers. Because of their small size, they have unique optical and electrical properties, resulting in quantum confinement of electrons and holes within the material. This confinement results in discrete energy levels, and the energy of the confined particles is determined by the size of the QDs QDs could be used in a variety of applications, including displays, solar cells, medical imaging, and quantum computing.. They are typically only a few nanometers in size. QDs can be employed as a light-sensitive substance, also referred to as a photoconductive substance, in a photodetector.

Cattle Feeding Precision by Automatic Feeding Systems
Livestock farming is experiencing a significant shift towards automation to reduce the many repetitive tasks requiring little skills and high workloads. For farmers, automatic feeding systems for ruminants can be an excellent way to reduce their daily workload and improve animal welfare and production quality. Studies have demonstrated that adopting automatic feeding systems leads to lower energy requirements, lower feed waste, and improved animal welfare, which unequivocally aligns with the farmers' perspective. However, to maximize the flexibility of the feeding robots and reap the benefits, thorough economic and structural planning that considers all of the farming site's features is necessary. Additionally, automatic feeding systems can help involve younger generations in animal farming and increase inclusivity, which may foster female entrepreneurship, all while maintaining good feeding practices.

Therapeutic Potential of Hops
The medicinal potential of hop (Humulus lupulus L.) is widely cited in ancient literature and is also allowed in several official pharmacopoeias for the treatment of a variety of ailments, mainly related to anxiety states. This is due to the plethora of phytoconstituents (e.g., bitter acids, polyphenols, prenyl flavonoids) present in the female inflorescences, commonly known as cones or strobili, endowed with anti-inflammatory, antioxidant, antimicrobial, and phytoestrogen activities. Hop has attracted the interest of the scientific community due to the presence of xanthohumol, whose strong anti-cancer activity against various types of cancer cells has been well documented, and for the presence of 8-prenyl naringenin, the most potent known phytoestrogen. Studies in the literature have also shown that hop compounds can hinder numerous signalling pathways, including ERK1/2 phosphorylation, regulation of AP-1 activity, PI3K-Akt, and nuclear factor NF-κB, which are the main targets of the antiproliferative action of bitter acids and prenylflavonoids.

Comprehensive Evaluation of Fermented Foods Based on Metabolomics
Fermentation is an important process that can provide new flavors and nutritional and functional foods, to deal with changing consumer preferences. Fermented foods have complex chemical components that can modulate unique qualitative properties. Consequently, monitoring the small molecular metabolites in fermented food is critical to clarify its qualitative properties and help deliver personalized nutrition. In recent years, the application of metabolomics to nutrition research of fermented foods has expanded. In this review, we examine the application of metabolomics technologies in food, with a primary focus on the different analytical approaches suitable for food metabolomics and discuss the advantages and disadvantages of these approaches. In addition, we summarize emerging studies applying metabolomics in the comprehensive analysis of the flavor, nutrition, function, and safety of fermented foods, as well as emphasize the applicability of metabolomics in characterizing the qualitative properties of fermented foods.

NHRE Deployment
Despite globally progressing energy transition, the deployment of non-hydropower renewable energy (NHRE) in developing countries varies by country and overall is moderate. This entry aims to explain why developing economies with significant challenges in the energy sector are not actively engaged in NHRE diffusion. In doing so, the entry reviews scholarly work on renewable energy (RE) deployment in developing countries and presents a two-stage analytical framework for assessing the NHRE development status. The procedure helps assess the current situation in the national energy sectors in connection to their economic growth and development, environmental sustainability and energy security. At the next stage, the framework lets analyse the preparedness of the national energy sectors for NHRE diffusion. The analysis spans six dimensions: structure of energy sector, RE regulation, institutions and governance, capital and investment, infrastructure and business environment, and human capital. The two-stage analytical framework assists in checking the hypothesis that more advanced economically and institutionally countries are more likely to commence NHRE development.

InN SAs for Ultrafast Lasers
New fabrication methods are strongly demanded for the development of thin-film saturable absorbers with improved optical properties (absorption band, modulation depth, nonlinear optical response). In this sense, we investigate the performance of indium nitride (InN) epitaxial layers with low residual carrier concentration (<1018 cm^-3), which results in improved performance at telecom wavelengths (1560 nm). These materials have demonstrated a huge modulation depth of 23% and a saturation fluence of 830 uJ/cm2, and a large saturable absorption around -3 x10^4 cm/GW has been observed, attaining an enhanced, nonlinear change in transmittance. We have studied the use of such InN layers as semiconductor saturable absorber mirrors (SESAMs) for an erbium (Er)-doped fiber laser to perform mode-locking generation at 1560 nm. We demonstrate highly stable, ultrashort (134 fs) pulses with an energy of up to 5.6 nJ.a

Green Wave
The concept of a Green Wave, i.e., the coordinated switching of traffic lights in order to favor a single direction and reduce congestion, is often discussed as a simple mechanism to avoid breaking and accelerating, thereby reducing fuel consumption. On the other hand, making car use more attractive might also increase emissions.

Injuries in Wheelchair Basketball Players
Wheelchair basketball (WB) is a Paralympic sport played by two teams of five players each, comprising players with physical impairments who can be allocated to eight different classes (1.0–4.5). The game proceeds at a fast pace, in which, the teams seek to score points in the opponent’s basket. This modality is popular worldwide and has been present in all editions of the Paralympic Games. Due to being a contact sport and due to the sport’s mechanics, in which, frequent shoulder movements are performed (throwing, passing, chair touching), it is expected that this practice contributes to sports injuries.
