Peripheral Muscle Fatigue
Muscle fatigue is defined as a decrease in maximal force or power generated in response to contractile activity, and it is a risk factor for the development of musculoskeletal injuries. One of the many stressors imposed on skeletal muscle through exercise is the increased production of reactive oxygen species (ROS) and reactive nitrogen species (RNS), which intensifies as a function of exercise intensity and duration. The progressive reduction in muscle fibers’ ability to generate force originates at different levels of the motor system and can be categorized into two types, namely, central and peripheral fatigue. Peripheral mechanisms of fatigue refer to activity-induced mechanical failure through processes at or distal to neuromuscular junctions, so they can be attributed to neuromuscular transmission and excitation–contraction coupling.

Network Sovereignty
Network Sovereignty is the effort of a governing entity, such as a state, to create boundaries on a network and then exert a form of control, often in the form of law enforcement over such boundaries. Much like states invoke sole power over their physical territorial boundaries, state sovereignty, such governing bodies also invoke sole power within the network boundaries they set and claim network sovereignty. In the context of the Internet, the intention is to govern the web and control it within the borders of the state. Often, that is witnessed as states seeking to control all information flowing into and within their borders. The concept stems from questions of how states can maintain law over an entity such like the Internet, whose infrastructure exists in real space, but its entity itself exists in the intangible cyberspace. Some Internet Scholars, such as Joel R. Reidenberg, argue, "Networks have key attributes of sovereignty: participant/citizens via service provider membership agreements, 'constitutional' rights through contractual terms of service, and police powers through taxation (fees) and system operator sanctions." Indeed, many countries have pushed to ensure the protection of their citizens' privacy and of internal business longevity by data protection and information privacy legislation (see the EU's Data Protection Directive, the UK's Data Protection Act 1998). Network Sovereignty has implications for state security, Internet governance, and the users of the Internet's national and international networks.

Xbox 360 System Software
The Xbox 360 system software or the Xbox 360 Dashboard is the updateable software and operating system for the Xbox 360. It formerly resided in a 16 MB file system. However, starting with the NXE Update, more storage became a requirement, rectified by either having a Hard Drive installed, or one of the later revisions of the console with adequate flash storage embedded within the console. The system software has access to a maximum of 32 MB of the system's Random Access Memory. The updates can be downloaded from the Xbox Live service directly to the Xbox 360 and subsequently installed. Microsoft has also provided the ability to download system software updates from their respective official Xbox website to their PCs and then storage media, from which the update can be installed to the system. The Xbox 360 game system allows users to download applications that add to the functionality of the dashboard. Most apps required the user to be signed into a valid Xbox Live Gold account in order to use the features advertised for the given app. But as of the 2.0.16756.0 update, most apps do not require an Xbox Live Gold Subscription to access them, although the app may have its own subscription to be able to use it. With the exception of a few early apps, Microsoft has added partners to develop apps for the Xbox 360 system since the New Xbox Experience (NXE) Dashboard update in 2008. Following the success of Xbox One preview program launched in 2014, in March 2015, Microsoft announced the Xbox 360 preview program to the public.

Forgiveness Scale
A forgiveness scale is a psychological test that attempts to measure a person's willingness to forgive. A true definition of forgiveness is debated by many researchers, yet Hargrave suggests that forgiveness refers to releasing resentment towards an offender. Forgiveness is a complex phenomenon which involves cognitive, affective, behavioural, motivational, decisional and interpersonal elements. Forgiveness is thought to be central to human functioning and important in restoring interpersonal relationships. It is an effective intervention to problems caused by anger, depression, drug abuse, guilt and moral development. Due to the different conceptualisations of forgiveness, different scales have been developed to measure the ability in different ways. Examples of forgiveness scales include the Forgiveness scale of the Interpersonal Relationship Resolution Scale; the Marital Offence-Specific Forgiveness Scale; the Workplace Forgiveness Scale; and the Tendency to Forgive scale. Forgiveness can also be measured via methods which are not empirical scales. These may come in the form of biological measures; such as chemical, central and peripheral physiological measures, as well as behavioural measures; and measures of self forgiveness. Studies have found that compared to participants without past suicide attempts, those with past suicide attempts scored on the Forgiveness Scale as being significantly less believing of forgiveness by others, were less likely to forgive themselves, and to a lesser degree, were less forgiving of others.

List of Vaccine Topics
This is a list of vaccine-related topics. A vaccine is a biological preparation that improves immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism, and is often made from weakened or killed forms of the microbe or its toxins. The agent stimulates the body's immune system to recognize the agent as foreign, destroy it, and "remember" it, so that the immune system can more easily recognize and destroy any of these microorganisms that it later encounters.

Virus Nanotechnology
Virus nanotechnology is the use of viruses as a source of nanoparticles for biomedical purposes. Viruses are made up of a genome and a capsid; and some viruses are enveloped. Most virus capsids measure between 20-500 nm in diameter. Because of their nanometer size dimensions, viruses have been considered as naturally occurring nanoparticles. Virus nanoparticles have been subject to the nanoscience and nanoengineering disciplines. Viruses can be regarded as prefabricated nanoparticles. Many different viruses have been studied for various applications in nanotechnology: for example, mammalian viruses are being developed as vectors for gene delivery, and bacteriophages and plant viruses have been used in drug delivery and imaging applications as well as in vaccines and immunotherapy intervention.
