Canopy
In biology, the canopy is the aboveground portion of a plant cropping or crop, formed by the collection of individual plant crowns. In forest ecology, canopy also refers to the upper layer or habitat zone, formed by mature tree crowns and including other biological organisms (epiphytes, lianas, arboreal animals, etc.). The communities that inhabit the canopy layer are thought to be involved in maintaining forest diversity, resilience, and functioning. Sometimes the term canopy is used to refer to the extent of the outer layer of leaves of an individual tree or group of trees. Shade trees normally have a dense canopy that blocks light from lower growing plants.

The Composition and Structure of Silk Fibroin
Silk fibroin is the principal component of raw silk and represents an extensively studied and utilized biopolymer. Silk fibroin is composed by three chains, light, heavy, and P25 protein. Heavy chain is rigorously organized in redundant aminoacidic sequences rich in glycine and alanine, secondary structure is organized in anti-parallel β-sheets that in turn form β-crystallites stacked in nano-fibrils. Those peculiar fibroin’s structural and compositional elements are crucial to determine the excellent physical properties, such as strength and toughness. Besides these characteristics, the processability and biocompatibility have attracted significant attention for the fabrication of several biomaterials suitable in many fields of application.

Erysipelas
Erysipelas (/ˌɛrəˈsɪpələs/) is a relatively common bacterial infection of the superficial layer of the skin (upper dermis), extending to the superficial lymphatic vessels within the skin, characterized by a raised, well-defined, tender, bright red rash, typically on the face or legs, but which can occur anywhere on the skin. It is a form of cellulitis and is potentially serious. Erysipelas is usually caused by the bacteria Streptococcus pyogenes, also known as group A β-hemolytic streptococci, through a break in the skin such as from scratches or an insect bite. It is more superficial than cellulitis, and is typically more raised and demarcated. The term is from Greek ἐρυσίπελας (erysípelas), meaning "red skin". In animals, erysipelas is a disease caused by infection with the bacterium Erysipelothrix rhusiopathiae. The disease caused in animals is called Diamond Skin Disease, which occurs especially in pigs. Heart valves and skin are affected. Erysipelothrix rhusiopathiae can also infect humans, but in that case, the infection is known as erysipeloid.

Perceived Sensory Dimensions
Perceived Sensory Dimensions (PSDs) is a tool that defines eight different cultural ecosystem services. They correspond to different human needs (rest, exercise, socialising, pleasure, or security) resulting in rehabilitation and health and well-being promotion. An experiment was conducted to study the potential of PSDs to restore people who experienced stressful accidents. One hundred and fifty-seven participants were recruited and asked first to watch a film clip of serious accidents, then to look at the pictures, depicting one particular type of PSDs, while listening to its respective audio recording. Their stress levels were measured before exposure to the stressor (baseline), after exposure to the stressor (pre-test), and after exposure to a particular type of PSDs (post-test). The results show that all eight PSDs effectively provide mental recovery, but there are statistical differences in their potentials. As such, it is proposed that the combined potential of the PSDs is needed, and should be used to increase the capacity and supply of health-promoting urban green areas

Sportsmanship
Sportsmanship is an aspiration or ethos that a sport or activity will be enjoyed for its own sake. This is with proper consideration for fairness, ethics, respect, and a sense of fellowship with one's competitors. A "sore loser" refers to one who does not take defeat well, whereas a "good sport" means being a "good winner" as well as being a "good loser" (someone who shows courtesy towards another in a sports game).

Substance Release from Polyelectrolyte Microcapsules
Controlled release of substance from polyelectrolyte microcapsules is a triggered degradation of the microcapsule membrane that is extensive enough to release the contained substances out into the environment. Membrane degradation can be a result of enzymatic digestion, ultrasound or light exposure, heating, application of a magnetic field, pH or ionic strength changes in the solution or bacteria-mediated processes. This technology can be used for the targeted release of drugs, and for the development of self-healing materials and new generation pesticides.

Energy-Efficiency Passive Strategies for Mediterranean Climate
The main objective and function of passive solutions are to contribute to the natural cooling or heating of the building. They are constructive technologies integrated within buildings. The exchange of thermal energy takes place by natural means that, when dimensioned correctly, can significantly reduce a household’s energy bills. Several passive strategies, namely natural ventilation, shading devices, overhangs, and daylighting, associated with the building envelope’s characteristics are important passive design parameters that should be given particular attention to highlighting the potential of buildings for energy efficiency.

Horseshoe
A horseshoe is a fabricated product, normally made of metal, although sometimes made partially or wholly of modern synthetic materials, designed to protect a horse hoof from wear. Shoes are attached on the palmar surface (ground side) of the hooves, usually nailed through the insensitive hoof wall that is anatomically akin to the human toenail, although much larger and thicker. However, there are also cases where shoes are glued. The fitting of horseshoes is a professional occupation, conducted by a farrier, who specializes in the preparation of feet, assessing potential lameness issues, and fitting appropriate shoes, including remedial features where required. In some countries, such as the UK, horseshoeing is legally restricted to people with specific qualifications and experience. In others, such as the United States, where professional licensing is not legally required, professional organizations provide certification programs that publicly identify qualified individuals. Horseshoes are available in a wide variety of materials and styles, developed for different types of horse and for the work they do. The most common materials are steel and aluminium, but specialized shoes may include use of rubber, plastic, magnesium, titanium, or copper. Steel tends to be preferred in sports in which a strong, long-wearing shoe is needed, such as polo, eventing, show jumping, and western riding events. Aluminium shoes are lighter, making them common in horse racing where a lighter shoe is desired, and often facilitate certain types of movement; they are often favored in the discipline of dressage. Some horseshoes have "caulkins", "caulks", or "calks": protrusions at the toe or heels of the shoe, or both, to provide additional traction. When kept as a talisman, a horseshoe is said to bring good luck. A stylized variation of the horseshoe is used for a popular throwing game, horseshoes.

Melatonin as a Neurotrophic Factor
Melatonin, N-acetyl-5-hydroxytryptamine, is a hormone that synchronizes the internal environment with the photoperiod. It is synthesized in the pineal gland and greatly depends on the endogenous circadian clock located in the suprachiasmatic nucleus and the retina’s exposure to different light intensities. Among its most studied functions are the regulation of the waking-sleep rhythm and body temperature. Furthermore, melatonin has pleiotropic actions, which affect, for instance, the modulation of the immune and the cardiovascular systems, as well as the neuroprotection achieved by scavenging free radicals.

Andalusian Arabic
Andalusian Arabic, also known as Andalusi Arabic, was a variety or varieties of Arabic spoken in Al-Andalus, the regions of the Iberian Peninsula (modern Spain and Portugal) under Muslim rule (and for some time after) from the 9th century to the 17th century. It became an extinct language in Iberia after the expulsion of the former Hispanic Muslims, which took place over a century after the Granada War by the Catholic Monarchs of Spain. Once widely spoken in Iberia, the expulsions and persecutions of Arabic speakers caused an abrupt end to the language's use on the peninsula. Its use continued to some degree in North Africa after the expulsion, although Andalusi speakers were rapidly assimilated by the Maghrebi communities to which they fled.

Entoptic Phenomenon
Entoptic phenomena (from grc ἐντός (entós) 'within', and ὀπτικός (optikós) 'visual') are visual effects whose source is within the human eye itself. (Occasionally, these are called entopic phenomena, which is probably a typographical mistake.) In Helmholtz's words: "Under suitable conditions light falling on the eye may render visible certain objects within the eye itself. These perceptions are called entoptical."

Biofuel production from different sources
Due to the depletion of fossil fuels, biofuel production from renewable sources has gainedinterest. Malaysia, as a tropical country with huge resources, has a high potential to produce differenttypes of biofuels from renewable sources. In Malaysia, biofuels can be produced from various sources,such as lignocellulosic biomass, palm oil residues, and municipal wastes. Besides, biofuels are dividedinto two main categories, called liquid (bioethanol and biodiesel) and gaseous (biohydrogen andbiogas). Malaysia agreed to reduce its greenhouse gas (GHG) emissions by 45% by 2030 as theysigned the Paris agreement in 2016. Therefore, we reviewed the status and potential of Malaysia asone of the main biofuel producers in the world in recent years. The role of government and existingpolicies have been discussed to analyze the outlook of the biofuel industries in Malaysia.

Oral Mucosal Pain
The oral cavity is a portal into the digestive system, which exhibits unique sensory properties. Like facial skin, the oral mucosa needs to be exquisitely sensitive and selective, in order to detect harmful toxins versus edible food. Chemosensation and somatosensation by multiple receptors, including transient receptor potential channels, are well-developed to meet these needs. In contrast to facial skin, however, the oral mucosa rarely exhibits itch responses. Like the gut, the oral cavity performs mechanical and chemical digestion. Therefore, the oral mucosa needs to be insensitive, to some degree, in order to endure noxious irritation. Persistent pain from the oral mucosa is often due to ulcers, involving both tissue injury and infection. Trigeminal nerve injury and trigeminal neuralgia produce intractable pain in the orofacial skin and the oral mucosa, through mechanisms distinct from those seen in the spinal area, which is particularly difficult to predict or treat. The diagnosis and treatment of idiopathic chronic pain, such as atypical odontalgia (idiopathic painful trigeminal neuropathy or post-traumatic trigeminal neuropathy) and burning mouth syndrome, remain especially challenging. The central integration of gustatory inputs might modulate chronic oral and facial pain. A lack of pain in chronic inflammation inside the oral cavity, such as chronic periodontitis, involves the specialized functioning of oral bacteria. A more detailed understanding of the unique neurobiology of pain from the orofacial skin and the oral mucosa should help us develop novel methods for better treating persistent orofacial pain.
