Viral Enteritis in Cattle
Livestock products supply about 13 percent of energy and 28 percent of protein in diets consumed worldwide. Diarrhea is a leading cause of sickness and death of beef and dairy calves in their first month of life and also affecting adult cattle, resulting in large economic losses and a negative impact on animal welfare. Despite the usual multifactorial origin, viruses are generally involved, being among the most important causes of diarrhea. There are several viruses that have been confirmed as etiological agents (i.e., rotavirus and coronavirus), and some viruses that are not yet confirmed as etiological agents.

Viral Encoded miRNAs in Tumorigenesis
About 15% of all human cancers have a viral etiology. Although progress has been made, understanding the viral oncogenesis and associated molecular mechanisms remain complex. The discovery of cellular miRNAs has led to major breakthroughs. Interestingly, viruses have also been discovered to encode their own miRNAs. These viral, small, non-coding miRNAs are also known as viral-miRNAs (v-miRNAs).

Viral Ejection Proteins
Genes encoding ejection proteins are commonly found in Podoviridae phages that infect Gram-negative bacteria, including Enterobacteriaceae, Mycobacteria, Pseudomonadaceae, and Cyanobacteria.

Viral Eco-Genomic Tools for Aquatic Biomonitoring
Enteric viruses (EVs) occurrence within aquatic environments varies and leads to significant risk on public health of humans, animals, and diversity of aquatic taxa. Early and efficacious recognition of cultivable and fastidious EVs in aquatic systems are important to ensure the sanitary level of aquatic water and implement required treatment strategies. In combination with bioinformatics techniques, genetic tools including cloning sequencing analysis, DNA microarray, next-generation sequencing (NGS), and metagenomic sequencing technologies are implemented to make informed decisions about the global burden of waterborne EVs-associated diseases.

VIPS
VIPS is an open source image processing software package. It is particularly good with large images, works with multi-core processors, working with colour, scientific analysis and general research & development. It was developed during and is the product of several European research projects (VASARI, MARC, ACOHIR, Viseum) which were primarily about Imaging art, but which demanded a new approach to image processing. Compared to most image processing libraries VIPS needs little RAM and runs quickly, especially on machines with more than one CPU. This is primarily due to its architecture which automatically parallelises the image workflows. The software has two main parts: libvips is the image-processing library and nip2 is the graphical user-interface. The GUI aims to be about half-way between Photoshop and Excel. It is not designed for tasks such as retouching photographs, but more useful for the many other imaging tasks that programs like Photoshop are used for. Both work on Linux, Unix, Windows and Apple macOS (10.2 and later). VIPS is a standard package for many Linux distributions

Viper Venom Phospholipase A2
Viper venom phospholipase A2 enzymes (vvPLA2s) and phospholipase A2-like (PLA2-like) proteins are two of the principal toxins in viper venom that are responsible for the severe myotoxic and neurotoxic effects caused by snakebite envenoming, among other pathologies.

Violence Prevention Education in Healthcare
Violence from patients and visitors towards healthcare workers is a serious international issue affecting the safety and health of workers, quality of care, and healthcare system sustainability. The main intervention is violence prevention (VP) education for healthcare workers. Both the healthcare environment and reasons for patient violence are complex, making it challenging to evaluate VP education using traditional methods. An alternative realist evaluation approach offers the ability to understand how, why and for whom VP education is effective to prevent violence and related injuries.

Violence and Capacity to Hate
Modern Western society does not contemplate any space for the expression of hate and, as always happens in these cases, opposite emotions are stressed as a defensive mechanism. Indeed, we are a society based on the supposed freedom, equality and valorisation of minorities. This reaction formation, which involves the removal of an unpleasant emotion (i.e., hate, which is connected to fear as will be seen later), has the advantage of freeing our society from the unbearable feelings of guilt deriving from the idea of hating others, their role models, their experiences and their right to be in the world and organise their society differently from ours. In fact, those who never hate, cannot feel guilty.

Vinylidene Fluoride
1,1-difluoroethylene (VDF) is one of the major fluoromonomers, which are the feedstock for the production of various resins, rubbers membrane and paints. The polymers derived from VDF (PVDF) or co-polymers with unique chemical resistance, stability at elevated temperatures, oxidation resistance, weatherability, piezoelectricity, dielectric and thermoelectricity, find wide applications in areas including petrochemical, electronic and electrical, and fluorocarbon coating. VDF is the second largest product among fluorocarbons with an annual production capacity of above 53,000 tons. The demand for VDF is increasing rapidly. At present, in industry, VDF is usually produced via the dehydrochlorination of 1,1-difluoro-1-chloroethane (HCFC-142b) at reaction temperatures above 650 °C

Vinyl Ether
Vinyl ether is the organic compound with the formula O(CH=CH2)2. Other names include divinyl ether, divinyl oxide, ethenoxyethene. It is a colorless, volatile liquid. Under the tradename vinethene, vinyl ether was once used as an inhalation anesthetic. The analytical techniques used to study its pharmacology laid the groundwork for the testing of new anesthetic agents. Many divinyl ether derivatives of fatty acids exist in nature.
