In vitro. In vitro tooth wear models are carried out in the laboratory with no patient contact or involvement. They can involve techniques that solely mimic the earliest stages of erosive demineralisation (in which surface changes including softening occur without loss of bulk tissue) and techniques which involve bulk tissue loss (in which acids initiate surface softening followed by a mechanical process which removes the vulnerably softened tissue). The later model aims to mimic the clinical situation where the outcome is loss of enamel and dentine usually due to a multifactorial tooth wear process. In order to further simulate a process of alternate demineralisation and remineralisation a cyclic design may be employed to simulate tooth wear causing tissue loss. Most work in the field of tooth wear research has taken place in vitro and the advantages of this approach to modelling of tooth wear include the following: • achievability of a high degree of standardisation; • ability to control numerous variables (including acidic challenge and concentration, substrate type and nature); • inclusion of large sample sizes and use of control groups; • results can be obtained relatively rapidly with minimal expenditure in comparison with in vivo and in situ tooth wear research. Extrapolating the results of in vitro studies to the clinical tooth wear is problematical, in part due to the inability to replicate the complexity of the oral environment in the laboratory but also due to by the heterogeneity of the applied methodologies used in the laboratory. Therefore only potential trends may be suggested by early erosion models and tissue loss models (Xxxxxxxxxx et al., 2006). Review of the literature of all in vitro tooth wear research reveals some of the wide variation in methods employed for the following parameters: • type of tooth wear simulated (erosion; attrition; abrasion) • substrate (human enamel/dentine; bovine enamel/dentine; hydroxyapatite) • sample preparation (polished, virgin tooth surface) • study design (single/cyclic/alternating order of challenge and remineralisation periods, timing and number of cycles) • Erosive agent (chemistry/pH/immersion time/flow rate/temperature/volume- substrate ratio) • Tooth brush abrasion wear simulation, (tooth brush machine, brush design, brushing behaviour, toothpaste) • Attritional wear (two or three body wear behaviour, wear machine, , type of antagonist, antagonist geometry, frequency of change of antagonist, total number of...

  • Testing Landlord shall have the right to conduct annual tests of the Premises to determine whether any contamination of the Premises or the Project has occurred as a result of Tenant’s use. Tenant shall be required to pay the cost of such annual test of the Premises; provided, however, that if Tenant conducts its own tests of the Premises using third party contractors and test procedures acceptable to Landlord which tests are certified to Landlord, Landlord shall accept such tests in lieu of the annual tests to be paid for by Tenant. In addition, at any time, and from time to time, prior to the expiration or earlier termination of the Term, Landlord shall have the right to conduct appropriate tests of the Premises and the Project to determine if contamination has occurred as a result of Tenant’s use of the Premises. In connection with such testing, upon the request of Landlord, Tenant shall deliver to Landlord or its consultant such non-proprietary information concerning the use of Hazardous Materials in or about the Premises by Tenant or any Tenant Party. If contamination has occurred for which Tenant is liable under this Section 30, Tenant shall pay all costs to conduct such tests. If no such contamination is found, Landlord shall pay the costs of such tests (which shall not constitute an Operating Expense). Landlord shall provide Tenant with a copy of all third party, non-confidential reports and tests of the Premises made by or on behalf of Landlord during the Term without representation or warranty and subject to a confidentiality agreement. Tenant shall, at its sole cost and expense, promptly and satisfactorily remediate any environmental conditions identified by such testing in accordance with all Environmental Requirements. Landlord’s receipt of or satisfaction with any environmental assessment in no way waives any rights which Landlord may have against Tenant.

  • Manufacturing (a) The Supplier shall without limitation be responsible, at no additional cost to the Purchaser, for: sourcing and procuring all raw materials for the Products; obtaining all necessary approvals, permits and licenses for the manufacturing of the Products; providing sufficient qualified staff and workers to perform the obligations under this Purchase Agreement; implementing and maintaining effective inventory and production control procedures with respect to the Products; and handling other matters as reasonably requested by the Purchaser from time to time.

  • Tests 7.7.1 If the Contract Documents, laws, ordinances, rules, regulations or orders of any public authority having jurisdiction require any portion of the Work to be inspected, tested or approved, the Contractor shall give the Architect timely notice of its readiness so the Architect may observe such inspection, testing or approval. The Contractor shall bear all costs of such inspections, tests or approvals conducted by public authorities.

  • Product ACCEPTANCE Unless otherwise provided by mutual agreement of the Authorized User and the Contractor, Authorized User(s) shall have thirty (30) days from the date of delivery to accept hardware products and sixty (60) days from the date of delivery to accept all other Product. Where the Contractor is responsible for installation, acceptance shall be from completion of installation. Failure to provide notice of acceptance or rejection or a deficiency statement to the Contractor by the end of the period provided for under this clause constitutes acceptance by the Authorized User(s) as of the expiration of that period. The License Term shall be extended by the time periods allowed for trial use, testing and acceptance unless the Commissioner or Authorized User agrees to accept the Product at completion of trial use. Unless otherwise provided by mutual agreement of the Authorized User and the Contractor, Authorized User shall have the option to run testing on the Product prior to acceptance, such tests and data sets to be specified by User. Where using its own data or tests, Authorized User must have the tests or representative set of data available upon delivery. This demonstration will take the form of a documented installation test, capable of observation by the Authorized User, and shall be made part of the Contractor’s standard documentation. The test data shall remain accessible to the Authorized User after completion of the test. In the event that the documented installation test cannot be completed successfully within the specified acceptance period, and the Contractor or Product is responsible for the delay, Authorized User shall have the option to cancel the order in whole or in part, or to extend the testing period for an additional thirty (30) day increment. Authorized User shall notify Contractor of acceptance upon successful completion of the documented installation test. Such cancellation shall not give rise to any cause of action against the Authorized User for damages, loss of profits, expenses, or other remuneration of any kind. If the Authorized User elects to provide a deficiency statement specifying how the Product fails to meet the specifications within the testing period, Contractor shall have thirty (30) days to correct the deficiency, and the Authorized User shall have an additional sixty (60) days to evaluate the Product as provided herein. If the Product does not meet the specifications at the end of the extended testing period, Authorized User, upon prior written notice to Contractor, may then reject the Product and return all defective Product to Contractor, and Contractor shall refund any monies paid by the Authorized User to Contractor therefor. Costs and liabilities associated with a failure of the Product to perform in accordance with the functionality tests or product specifications during the acceptance period shall be borne fully by Contractor to the extent that said costs or liabilities shall not have been caused by negligent or willful acts or omissions of the Authorized User’s agents or employees. Said costs shall be limited to the amounts set forth in the Limitation of Liability Clause for any liability for costs incurred at the direction or recommendation of Contractor.
