Abstract: Current approaches create web based simulated lab type of setups for students/learners in which lab environment is created according to course of student. However, these conventional approaches require student systems to have some basic setup for working on virtual labs. Few available techniques also provide cloud-based virtual labs in which private cloud is created but they use open-source tool for creation. Further, available virtual lab techniques do not provide seamless integration with LMS. Present disclosure provides methods and systems for provisioning virtual lab with learning management system. The system provides virtual desktop that is created on an infrastructure-as-a-service platform. The learner desktop is accessed by a user/learner from respective existing computer system via LMS account. The virtual desktop includes hardware configuration and software packages required to solve one or more problems or perform one or more experiments related to course for which learners have enrolled in LMS.

Abstract: Packaging for prosthetic heart valves including an assembly for stabilizing dry prosthetic tissue implants such as heart valves during storage. The packaging assembly includes a primary sterile barrier that permits gas sterilization of the tissue implant, and a secondary sterile barrier that also prevents oxidation of the implant during long-term storage. Tissue heart valves may be placed or suspended within a cavity of an inner rigid tray with a gas-permeable lid sealed thereon, and a cap placed over the cavity to limit movement of the valve therein. The inner tray is placed within an outer sterile barrier, such as another rigid tray or a flexible pouch, and the assembly is then sterilized. The outer sterile barrier may include a double seal so that a first gas-permeable seal can be closed for sterilization, after which a second gas-impermeable seal can be closed to seal out any further oxygen contact with the tissue implant.

Abstract: Packaging for prosthetic heart valves including an assembly for stabilizing dry prosthetic tissue implants such as heart valves during storage. The packaging assembly can be used for storing a bioprosthetic heart valve without a liquid preservative solution. The packaging assembly can have a valve holder configured for removably attaching a bioprosthetic heart valve, a storage tray comprising an open end and a cavity, and a retaining member configured for removably attaching the valve holder. The retaining member can be generally planar and have a slot having a closed end and an open outer end. The valve holder can be configured to be retained at the closed end of the slot in the retaining member.

Abstract: Packaging for prosthetic heart valves including an assembly for securely retaining a heart valve within a jar and facilitating retrieval therefrom. The assembly includes a packaging sleeve that fits closely within the jar and has a clip structure for securing a valve holder. Contrary to previous designs, in one embodiment the valve holder is directed downward into the jar, and the valve is retained with an inflow end upward. The valve may have flexible leaflets, and a leaflet parting member on the end of the shaft extends through the leaflets and couples with the valve holder. The assembly of the packaging sleeve, valve, and holder can then be removed from the jar and a valve delivery tube connected with the holder, or to the leaflet parting member. The packaging sleeve may be bifurcated into two halves connected at a living hinge to facilitate removal from around the valve/holder subassembly.

Abstract: A packaging assembly for storing a bioprosthetic heart valve without a liquid preservative solution is provided. The packaging system includes a holder, a cage, a storage tray and an insert sized to provide a cap over the cavity of the storage tray. The holder comprises a shaft and an engagement structure configured for removably attaching a bioprosthetic heart valve. The cage comprises an upper end, the cage configured to at least partially enclose the bioprosthetic heart valve. The storage tray comprises a cavity for housing the cage. The insert comprises a slot having a closed central end and an open outer periphery, the shaft of the holder being non-rotatably retained at the closed central end. The insert defines a flat, generally planar disc comprising at least one of outward projections and flow passages. The packaging assembly does not comprise a liquid preservative solution.

Abstract: A computer implemented method for predicting dynamic pricing for a product or service is disclosed. The method comprises: receiving, at a server, transaction data for a plurality transactions relating to the product or service, the transaction data comprising transaction information indicating attributes of the transaction and booking information indicating attributes of the product or service; storing the transaction data on the server as a data set; calculating, in a derived variable calculation module of the server, derived variables for the data set from the transaction information and/or the booking information; generating, in a model generation module of the server, a model for the price of the product or service as a function of the derived variables; and predicting, in a price prediction module of the server, a price for the product or service using the model.

Abstract: A computerised method for managing travel expenditure is disclosed. The method comprises: receiving travel data for a traveller's proposed trip, the travel data comprising at least a travel budget and travel destination; receiving a user profile comprising at least an indication of spend level preference for the traveller; obtaining historic travel expenditure data for a plurality of customers; analysing the historic travel expenditure data in light of the travel data and user profile to determine an optimal proposed spend allocation for the traveller across different travel spend streams; and communicating the proposed spend allocation to the traveller along with a listing of potential merchants for each spend stream, the potential merchants being extracted from the historic travel expenditure data.
