Know the different body areas which act as physical barriers to infection. Know the different physical and biological defense mechanisms? Examples? Solution As per the rule i have answered your first question: Reoviridae: Reoviridae are currently classified into nine genera. The genomes of these viruses consist of 10 to 12 segments of dsRNA, each generally encoding one protein. The mature virions are non-enveloped. Their capsids, formed by multiple proteins, have icosahedral symmetry and are arranged generally in concentric layers. A distinguishing feature of the dsRNA viruses, irrespective of their family association, is their ability to carry out transcription of the dsRNA segments, under appropriate conditions, within the capsid. In all these viruses, the enzymes required for endogenous transcription are thus part of the virion structure. Orthoreoviruses: The orthoreoviruses (reoviruses) are the prototypic members of the virus Reoviridae family and representative of the turreted members, which comprise about half the genera. Like other members of the family, the reoviruses are non-enveloped and characterized by concentric capsid shells that encapsidate a segmented dsRNA genome. In particular, reovirus has eight structural proteins and ten segments of dsRNA. A series of uncoating steps and conformational changes accom.

In what ways do the experts foresee the use of both virtualization and cloud computing evolving in the future? Solution Use ofVirtualization and cloud computing security : • Self-defending VM security • Layered coordinated defenses • Security optimized for virtual and cloud environments • Visibility, reporting, and auditing • Encryption for virtual and cloud environments • Security that travels with data Security solutions should offer both agent-less and agent-based security options to provide flexible deployment alternatives and close security gaps unique to virtualized and cloud environments. Encryption addresses a range of security challenges related to virtualization and cloud computing. Standard 128-, 192-, or 256-bit encryption of storage volumes deters hackers from prying and thieving, and reduces the risk that the cloud storage devices could be sold or reused while they still contain confidential or private information. Encryption also greatly reduces the risk of malicious VM attacks; as long as the encryption key for the data stores have not been provided, even if rogue VMs reach data stores, volumes are unmountable and unreadable. Encryption with enterprise-controlled key management enables IT to comply with security best practices, internal governance, and external regulation. Data is kept secure, and the key management solution can provide monitoring, reporting, and auditing capabilities that provide visibility into data access. As a result, enterprises realize a significant reduction in the scope of compliance audits. Encryption for virtual and cloud environments: In summary, best practices for encryption for virtual and cloud data protection include: • Integration with leading cloud service providers and virtual environments. • Policy-based key management that determines where and when encrypted data can be accessed. • Identity-based and integrity-based server validation to determine which servers can access secure storage volumes and whether security is up-to-date on those servers prior to data access. • Business control of encryption keys, either on-site or through a separate SaaS service, to maintain a strict separation of duties between the business and cloud service provider..

In the Meselson Stahl experiment, E. coli was grown for many generations in a medium \"heavy\" nitrogen^15 N. Once the bacterial DNA was uniformly labeled, the bacteria were transferred to a medium containing the \"light\" nitrogen, ^14N. After ONE round of replication, DNA was extracted and subjected to density gradient centrifugation in cesium chloride. Upon inspection, there was only a single band of intermediate density DNA in the gradient. This proved that DNA replication CANNOT be conservative dispersive semiconservative conservative of dispersive continuous. Solution Answer is Dispersive replication. Dispersive replication would result in double-stranded DNA with both strands having mixtures of 15N and 14N DNA, either of which would have appeared as DNA of an intermediate density..

Was the communication among the participants in the case effective or not? Justify your answer (this is not just an opinion). West Coast Transit Company Profile West Coast Transit began as a small, charter airline in 2005. Its initial vision was providing affordable, on-the-hour flights from California-based airports to its three adjacent states: Arizona, Nevada, and Oregon. West Coast Transit recognized that the need for affordable and convenient flights out of California was high enough to sustain a business. The company began its success using smaller commuter planes to transport customers to surrounding airports. There was no flight longer than 2 hours and there was minimal service during the flight. The company’s mission was customer-focused, to provide an opportunity for companies to fly their employees at an affordable rate and whole families to travel affordably. West Coast Transit tripled in size after its first year. Growing demand required the addition of flights, employees, and larger airplanes. The founders of the company reevaluated the vision and future of West Coast Transit. The company were determined to maintain an emphasis on convenient, affordable flights and keep its focus on customer needs. This strategy proved successful. The company has established itself as a dominant regional competitor. West Coast Transit has over 10,000 employees and continues to see growth in its future. Most employees at West Coast Transit rave about the company and appreciate its friendly and employee-centered culture. The company’s leadership cares about its employees and makes every effort to provide them with satisfactory benefits. Most employees are enthusiastic about the impact they make on customers, their salaries and benefits, and the advancement opportunities the company provides. They feel valued and respected. One major complaint that a majority of the employees has is the turnaround demand. Employees are given very little time and support to complete a project. There is just too much work to be done. Most employees are successful under pressure, but would appreciate an environment that provides adequate time to complete projects productively.

Explain the differences between PL and PLE measurements; Explain why the PLE experiment can provide information about the absorption features of a semiconductor! Explain why PL spectrum is typically much narrower than absorption spectrum; Explain why we say optical transitions are \"vertical\". Solution the PL measurements are based on fixed energy excitation.and detection energy is varied.PLE is just reverse process we have detection energy fixed and excitation energy varied. PLE spectroscopy is a useful method to investigate the electronic level structure of materials with low absorption due to the superior signal-to-noise ratio of the method compared to absorption measurements. PL spectroscopy is a contactless, nondestructive method of probing the electronic structure of materials. Light is directed onto a sample, where it is absorbed and imparts excess energy into the material in a process calledphoto-excitation. One way this excess energy can be dissipated by the sample is through the emission of light, orluminescence. In the case of photo-excitation, this luminescence is calledphotoluminescence or PL. As fluorophores play the central role in fluorescence spectroscopy and imaging we will start with an investigation of their manifold interactions with light. Afluorophore is a component that causes a molecule to absorb energy of a specific wavelength and then re-remit energy at a different but equally specific wavelength. The amount and wavelength of the emitted energy depend on both the fluorophore and the chemical environment of the fluorophore. Fluorophores are also denoted as chromophores, historically speaking the part or moiety of a molecule responsible for its color. In addition, the denotation chromophore implies that the molecule absorbs light while fluorophore means that the molecule, likewise,emits light. The umbrella term used in light emission is luminescence, whereas fluorescence denotes allowed transitions with a lifetime in the nanosecond range from higher to lower excited singlet states of molecule.thats why narrower..
