Precision Livestock Farming
Precision livestock farming (PLF) has developed and concerned the whole sector: from cattle to pigs, to poultry, achieving the best results in cattle farms, especially in dairy farms. The technology that is affecting various aspects of dairy cattle breeding is certainly near infrared spectroscopy (NIRS) which is versatile and can be used on line/in line to evaluate and control the critical points of the production process by entering the PAT (process analytical technology). In the barn, NIRS currently can obtain information on the chemical-physical composition of raw materials, total mixed ration (TMR), feces and digestibility, chemical and technological analysis of milk. All this in a short time by eliminating the waiting times for analysis response and costs, allowing an improvement of livestock management. Many studies affirm the validity of NIRS as a reliable and predictive technology against multiple relevant parameters in matrices such as raw feed, TMR, feces, and milk.

Horses Facial Expressions Machine Recognition
Facial activity can convey valid information about the experience of pain in a horse. The scoring of facial activity is costly and depending on correct observation and interpretation by trained humans. Automatisation would greatly enhance the possibility to detect pain in horses. In humans, emotional states are detected in real time video using automated computer algorithms. However, the application of such methods to horses has proven difficult. Major barriers are the lack of sufficiently large, annotated databases for horses and difficulties in obtaining correct classifications of pain

Cell-Free Protein Synthesis of Unspecific Peroxygenases
Unspecific peroxygenases (UPOs, EC 1.11.2.1) are fungal biocatalysts that have attracted considerable interest for application in chemical syntheses due to their ability to selectively incorporate peroxide-oxygen into non-activated hydrocarbons. However, the number of available and characterized UPOs is limited, as it is difficult to produce these enzymes in homologous or hetero-logous expression systems.

Drivers for Digital Twin Adoption in Construction Industry
Digital twin (DT) is able to present digital replicas of existing assets, processes and systems. DT can integrate artificial intelligence, machine learning, and data analytics to create real-time simulation models. These models learn and update from multiple data sources to predict their physical counterparts’ current and future conditions. This has promoted its relevance in various industries, including the construction industry (CI). However, recognising the existence of a distinct set of factors driving its adoption has not been established. The drivers were identified through a systematic literature review approach and integrated into a classification framework to enhance its understanding. A conceptual framework was developed to enhance the successful adoption of DT in the CI based on the identified drivers.

Effect of Sodium Fluorescein on High-Grade Gliomas
High-grade gliomas (HGG) are the most common primary malignant brain cancer in adults. Complete surgical removal of HGG is known to increase the overall survival and progression-free survival. Fluorescence-guided surgery with 5-aminolevulinic acid (5-ALA) increases gross total resection considerably compared to white light surgery (65% vs. 36%). Recently, an off-label fluorophore, sodium fluorescein (SF), has become popular in fluorescence-guided surgery due to numerous utility benefits compared to 5-ALA, including lower cost, non-toxicity, easy administration during surgery and a wide indication for other CNS tumors.

Psychological Effects of Digital Companies’ Employees during COVID-19
The ways people use words online can furnish psychological processes about their beliefs, fears, thinking patterns, and so on. Extracting from online employees’ reviews on the workplace community websites, the psychological effects of employees during the phase of the COVID-19 pandemic can be quantified. Affected by the pandemic after 2020, although the overall evaluation of digital companies employees was tending to be better, were work–life balance, culture and values, senior management, career opportunities, and salary and benefits, which were still getting worse.

Photocatalyzed Production of Urea Using TiO2–Based Materials
Urea has been widely used in the agricultural industry as a fertilizer. It represents more than 50% of the nitrogen fertilizer market, and its global demand has increased more than 100 times in the last decades. In energy terms, urea has been considered a hydrogen–storage (6.71 wt.%) and ammonia–storage (56.7 wt.%) compound, giving it fuel potential. Urea properties meet the requirements of the US Department of Energy for hydrogen–storage substances, meanly because urea crystalizes, allowing storage and safe transportation. Conventional industrial urea synthesis is energy–intensive (3.2–5.5 GJ ton-1) since it requires high pressures and temperatures, so developing a photocatalyzed synthesis using TiO2 (Titanium dioxide) at ambient temperature and pressure is an attractive alternative to conventional synthesis.

Collective Spaces in Achieving Social Sustainability
The outdoor collective spaces in most residential areas play a major role in social stability and unification. These are important components of the housing environment because they provide places for complimentary activities of housing units, mainly social interaction. Thus, good outdoors should ensure good social relations, a good sense of belonging to the place, and a stable social life for the residents.

GNU Bison
GNU bison, commonly known as Bison, is a parser generator that is part of the GNU Project. Bison reads a specification of a context-free language, warns about any parsing ambiguities, and generates a parser (either in C, C++, or Java) which reads sequences of tokens and decides whether the sequence conforms to the syntax specified by the grammar. Bison by default generates LALR parsers but can also create GLR parsers. In POSIX mode, Bison is compatible with Yacc, but also has several extensions over this earlier program. Flex, an automatic lexical analyser, is often used with Bison, to tokenise input data and provide Bison with tokens. Bison was originally written by Robert Corbett in 1985. Later, in 1989, Robert Corbett released another parser generator named Berkeley Yacc. Bison was made Yacc-compatible by Richard Stallman. Bison is free software and is available under the GNU General Public License, with an exception (discussed below) allowing its generated code to be used without triggering the copyleft requirements of the licence.

Physics of the Future
Physics of the Future: How Science Will Shape Human Destiny and Our Daily Lives by the Year 2100 is a 2011 book by theoretical physicist Michio Kaku, author of Hyperspace and Physics of the Impossible. In it Kaku speculates about possible future technological development over the next 100 years. He interviews notable scientists about their fields of research and lays out his vision of coming developments in medicine, computing, artificial intelligence, nanotechnology, and energy production. The book was on the New York Times Bestseller List for five weeks. Kaku writes how he hopes his predictions for 2100 will be as successful as science fiction writer Jules Verne's 1863 novel Paris in the Twentieth Century. Kaku contrasts Verne's foresight against U.S. Postmaster General John Wanamaker, who in 1893 predicted that mail would still be delivered by stagecoach and horseback in 100 years' time, and IBM chairman Thomas J. Watson, who in 1943 is alleged to have said "I think there is a world market for maybe five computers." Kaku points to this long history of failed predictions against progress to underscore his notion "that it is very dangerous to bet against the future".

Relation (History of Concept)
The concept of relation as a term used in general philosophy has a long and complicated history. One of the interests for the Greek philosophers lay in the number of ways in which a particular thing might be described, and the establishment of a relation between one thing and another was one of these. A second interest lay in the difference between these relations and the things themselves. This was to culminate in the view that the things in themselves could not be known except through their relations. Debates similar to these continue into modern philosophy and include further investigations into types of relation and whether relations exist only in the mind or the real world or both. An understanding of types of relation is important to an understanding of relations between many things including those between people, communities and the wider world. Most of these are complex relations but of the simpler, analytical relations out of which they are formed there are generally held to be three types, although opinion on the number may differ. The three types are spatial relations which include geometry and number, relations of cause and effect, and the classificatory relations of similarity and difference that underlie knowledge. Going by different names in the sciences, mathematics, and the arts they can be thought of as three large families and it is the history of these that will be dealt with here.

Combination Therapy for Glioblastoma
Aggressive glioblastoma (GBM) has no known treatment as a primary brain tumor. Since the cancer is so heterogeneous, an immunosuppressive tumor microenvironment (TME) exists, and the blood–brain barrier (BBB) prevents chemotherapeutic chemicals from reaching the central nervous system (CNS), therapeutic success for GBM has been restricted. Drug delivery based on nanocarriers and nanotechnology has the potential to be a handy tool in the continuing effort to combat the challenges of treating GBM. Combination therapies may be enhanced by using nanotechnology-based delivery techniques. Nano-chemotherapy, nano-chemotherapy–radiation, nano-chemotherapy–phototherapy, and nano-chemotherapy–immunotherapy for GBM.

Tribe (Internet)
The term tribe or digital tribe is used as a slang term for an unofficial community of people who share a common interest, and usually who are loosely affiliated with each other through social media or other Internet mechanisms. The term is related to "tribe", which traditionally refers to people closely associated in both geography and genealogy. Nowadays, it looks more like a virtual community or a personal network and it is often called global digital tribe. Most anthropologists agree that a tribe is a (small) society that practices its own customs and culture, and that these define the tribe. The tribes are divided into clans, with their own customs and cultural values that differentiate them from activities that occur in 'real life' contexts. People feel more inclined to share and defend their ideas on social networks than they would dare to say to someone face to face. For example, it would be ridiculous to 'poke' someone in real life.

Graphene Based TE Materials
Graphene is a two-dimensional (2D) monolayer material with only one carbon atom thickness. The most promising method for transparent conductive graphene electrodes in optoelectronic devices is reportedly synthesized via chemical vapor deposition, where graphene films are deposited directly on a substrate such as Cu foil by passing a carbon source through a high-temperature vacuum chamber, and the synthesized graphene is transferred to the target substrate using a support film such as poly (methyl methacrylate).
