Zoo Food Preparation and Presentation
From its foundations in agricultural science, zoo animal nutrition has developed into a biologically informed, evidence-based discipline. However, some facets of nutrition still make use of a more traditional approach, such as the field of zoo presentation. For example, it is common practice to prepare animal diets by chopping them into bite-size chunks, yet there is limited peer-reviewed evidence that explains the benefits and welfare implications of this practice. The chopping and placement of foods can alter desiccation rates, nutrient breakdown, and food contamination, so it is important to evaluate the implications of current practices. Here, the published literature on the behavioral impacts of different food presentation formats (such as clumped and scattered, and chopped and whole) is reviewed, with reference to a range of taxa. The current state of knowledge of the nutritional and microbiological effects of food presentation practices are also reviewed. Relevant research is available on the behavioral effects of some forms of zoo food presentation; however, relatively little research has been conducted on their nutrient composition effects or desiccation rates. Similarly, there are gaps in terms of the species that have been investigated, with a few mammalian taxa dominating the food presentation literature. Future research projects covering social, behavioral, and welfare impacts, and the nutritional and microbiological consequences of food presentation would further evidence-based zoo and aquarium management practices. Similarly, qualitative research surrounding keeper perception of food presentation formats would help to identify challenges and opportunities in this field.

Legal Management
Legal management is an academic and professional discipline that is a hybrid between the study of law and management (i.e., business administration, public administration, etc.). Often, alumni of legal management programmes pursue a professional degree in law such as Juris Doctor (JD) or Bachelor of Laws (LL.B.) while some profess as paralegals, law clerks, political analysts, politicians, public administrators, entrepreneurs, business executives, or pursue careers in the academe. The degree was designed in the Philippines and was first introduced in Ateneo de Manila University in the 1980s by former Philippine Supreme Court Chief Justice Renato Corona. A similar degree known as Legal Studies is offered at the University of California Berkeley, but without management courses. Legal management student organisations across the Philippines are represented by the Alliance of Legal Management Associations of the Philippines (ALMAP) to the Securities and Exchange Commission, as a non-stock, non-profit, student-run corporation.

FIB-SEM Tomography: Fundamentals and Applications in Materials Sciences
Focused ion beam (FIB)-scanning electron microscopy (SEM) tomography is an extremely important and reliable technique for the three-dimensional reconstruction of microscopic structures with nanometric resolution, with great potential to be integrated with other analytical techniques. FIB-SEM tomography plays a crucial role in the development of innovative multiscale and multimodal correlative microscopy workflows because it can be seamlessly integrated with other imaging modalities, as the reconstruction range bridges the gap between the non-destructive X-ray families of tomographic techniques, which provide sub-micron resolution, and the nano- to atomic-scale resolution achieved by transmission electron microscopy (TEM) tomography.

Hydroxytyrosol in Food Products
Hydroxytyrosol (HT) is an amphipathic functional phenol found in the olive tree, both in its leaves and fruits, in free or bound forms, as well as in olive oil and by-products of olive oil manufacture. It is recognized as safe by the European Food Safety Authority (EFSA) and Food and Drug Administration (FDA) and has obvious health effect when consumed regularly with the prerequisite to contain at least 5 mg/20 g oil of HT and related compounds. According to the dietary data from the European Union, it is estimated that the mean values of HT consumption in adults is far from the daily recommended intake, which relays the importance of the incorporation of HT in other types of products.

Degradation of Antibiotics
Antibiotics are the therapeutic option for countless infections treatment; unfortunately, they are the second most common group of drugs in wastewaters worldwide due to failures in industrial waste treatments and their irrational use in humans and animals. Several techniques have been assayed for the degradation and mineralisation of antibiotics to reduce the environmental impact; strategies focused on physical, chemical, biological, and combined process design for degradation.

Insulin Effects on Target Tissues
Glucose levels in blood must be constantly maintained within a tight physiological range to sustain anabolism. Insulin regulates glucose homeostasis via its effects on glucose production from the liver and kidneys and glucose disposal in peripheral tissues (mainly skeletal muscle). Blood levels of glucose are regulated simultaneously by insulin-mediated rates of glucose production from the liver (and kidneys) and removal from muscle; adipose tissue is a key partner in this scenario, providing nonesterified fatty acids (NEFA) as an alternative fuel for skeletal muscle and liver when blood glucose levels are depleted. During sleep at night, the gradual development of insulin resistance, due to growth hormone and cortisol surges, ensures that blood glucose levels will be maintained within normal levels by: (a) switching from glucose to NEFA oxidation in muscle; (b) modulating glucose production from the liver/kidneys. After meals, several mechanisms (sequence/composition of meals, gastric emptying/intestinal glucose absorption, gastrointestinal hormones, hyperglycemia mass action effects, insulin/glucagon secretion/action, de novo lipogenesis and glucose disposal) operate in concert for optimal regulation of postprandial glucose fluctuations. The contribution of the liver in postprandial glucose homeostasis is critical. The liver is preferentially used to dispose over 50% of the ingested glucose and restrict the acute increases of glucose and insulin in the bloodstream after meals, thus protecting the circulation and tissues from the adverse effects of marked hyperglycemia and hyperinsulinemia.

Macroalgae
What are algae? Algae are organisms that perform photosynthesis; that is, they absorb carbon dioxide and release oxygen (therefore they have chlorophyll, a group of green pigments used by photosynthetic organisms that convert sunlight into energy via photosynthesis) and live in water or in humid places. Algae have great variability and are divided into microalgae, small in size and only visible through a microscope, and macroalgae, which are larger in size, up to more than 50 m (the maximum recorded was 65 m), and have a greater diversity in the oceans. Thus, the term “algae” is commonly used to refer to “marine macroalgae or seaweeds”. It is estimated that 1800 different brown macroalgae, 6200 red macroalgae, and 1800 green macroalgae are found in the marine environment. Although the red algae are more diverse, the brown ones are the largest.

The Heart of Borneo
The HoB is situated in Borneo, the third-largest island in the world next to Greenland and New Guinea. It is shared by Indonesia (Kalimantan) covering an area of 745,567 square kilometers (km2), Borneo Malaysia, comprising the states of Sarawak and Sabah with an area of 124,449 km2 and 73,711 km2, respectively, and a small-nation sate, Brunei Darussalam (5765 km2). The rainforests in Borneo, which evolved between 100 and 150 million years ago, are among the most biologically diverse on Earth. Representing just one percent of the earth’s terrestrial surface, the island of Borneo holds about six percent of the world’s plant and animal species. There are approximately 15,000 flowering plants and 3000 species of trees found in Borneo’s forest, including 6000 endemic species. The biologically diverse island is recognized as a globally significant biodiversity ‘hotspot’. In addition, the uplands of Borneo are a source of at least 14 of the 20 major rivers on the island. Thus, environmentally sustainable resource management is critically important in maintaining the ecological health of riverine systems, which underpin the socio-economic progress of 17 million people in Borneo.

Glory
Glory (from the Latin gloria, "fame, renown") is used to describe the manifestation of God's presence as perceived by humans according to the Abrahamic religions. Divine glory is an important motif throughout Christian theology, where God is regarded as the most glorious being in existence, and it is considered that human beings are created in the Image of God and can share or participate, imperfectly, in divine glory as image-bearers. Thus Christians are instructed to "let your light shine before men, that they may see your good works, and glorify your Father in heaven".

CO2 and H2S Separation Technologies
The emerging economic activities, modernization of technology and progressive transition from coal utilization to low-carbon fuel drive the rising energy demand. Natural gas is well-known as clean energy resources for electricity generation and fuel for transportation. Currently, CO2 and H2S content in gas fields accounts for up to 90% and 15%, respectively. Apart from fulfilling the market demand, the removal of these contaminants from natural gas is critical due to their corrosive natures, low heating value of natural gas and  greenhouse gas effect. To date, numerous gas fields remain unexplored due to high presence of contaminants. Several technologies such as absorption, adsorption, membrane separation and cryogenic distillation have been developed for natural gas sweetening. This entry comprehensively discussed the mechanisms and state-of-the-art of these conventional technologies.

Italian Fiscal Code Card
The Italian fiscal code card, officially known as Italy's Codice fiscale, is the tax code card in Italy, similar to a Social Security Number (SSN) card in the United States or the National Insurance Number issued in the United Kingdom. The tax code in Italy is an alphanumeric code of 16 characters. The card serves to identify unambiguously individuals residing in Italy irrespective of residency status. Designed by and for the Italian tax office, it is now used for several other purposes, e.g. uniquely identifying individuals in the health system, or natural persons who act as parties in private contracts. The number is issued by the Italian tax office. Each person in the past was handed a plastic card with a magnetic strip, bearing the tax code as well as the surname, given name(s), sex, place and province of birth (or country of birth if foreign), date of birth and date of issue. Today, the tax or fiscal code card has been replaced by a combined Italian health insurance card for qualifying residents which shows an expiration date.
