Deep eutectic solvents Clause Samples

Deep eutectic solvents. There are a few applications of DES in the extraction of natural products. This is probably due to their high viscosity and most are in nearly solid state at room temperature. However, DES made of glycerol and choline have relative low viscosity and are good solvents for enzyme reaction. Hydrolases show good catalytic activity in DES including choline chloride-acetamide, choline chloride-glycerol, choline chloride-urea. In those DES, lyophilized Candida antarctica lipase B shows higher activity than that in the conventional solvent, toluene. Particularly, in choline chloride-glycerol, the conversion is much higher than in toluene (22% vs 5%) with lyophilized Burkholderia cepacia lipase. Furthermore, the enzyme activity of lyophilized Candida antarctica lipase B did not decrease in choline chloride-urea at 60 oC over 90 min (▇▇▇▇▇ et al., 2008). The high activity and stability of hydrolases in DES show the promise of DES as solvents in biotransformation. The enzymatic transesterification of Miglyol oil 812 catalyzed by Novozym 435, a commercial immobilized Candida antarctica lipase B, showed high reaction rates in choline acetate:glycerol (1:1.5) at 50 oC. The high conversion rate of up to 97% ensures the further exploration of DES as potential solvents in enzyme reactions (▇▇▇▇ et al., 2011).

  • Influenza Vaccine Upon recommendation of the Medical Officer of Health, all employees shall be required, on an annual basis to be vaccinated and or to take antiviral medication for influenza. If the costs of such medication are not covered by some other sources, the Employer will pay the cost for such medication. If the employee fails to take the required medication, she may be placed on an unpaid leave of absence during any influenza outbreak in the home until such time as the employee has been cleared by the public health or the Employer to return to the work environment. The only exception to this would be employees for whom taking the medication will result in the employee being physically ill to the extent that she cannot attend work. Upon written direction from the employee’s physician of such medical condition in consultation with the Employer’s physician, (if requested), the employee will be permitted to access their sick bank, if any, during any outbreak period. If there is a dispute between the physicians, the employee will be placed on unpaid leave. If the employee gets sick as a reaction to the drug and applies for WSIB the Employer will not oppose the application. If an employee is pregnant and her physician believes the pregnancy could be in jeopardy as a result of the influenza inoculation and/or the antiviral medication she shall be eligible for sick leave in circumstances where she is not allowed to attend at work as a result of an outbreak. This clause shall be interpreted in a manner consistent with the Ontario Human Rights Code.

  • Musculoskeletal Injury Prevention and Control The hospital in consultation with the Joint Health and Safety Committee (JHSC) shall develop, establish and put into effect, musculoskeletal prevention and control measures, procedures, practices and training for the health and safety of employees.

  • Unbundled Copper Loop – Designed (UCL-D) 2.4.2.1 The UCL-D will be provisioned as a dry copper twisted pair loop that is unencumbered by any intervening equipment (e.g., filters, load coils, range extenders, digital loop carrier, or repeaters). The UCL-D will be offered in two versions - Short and Long. 2.4.2.2 A short UCL-D (18,000 feet or less) is provisioned according to Resistance Design parameters, may have up to 6,000 feet of bridged tap and will have up to 1300 ohms of resistance. 2.4.2.3 The long UCL-D (beyond 18,000 feet) is provisioned as a dry copper twisted pair longer than 18,000 feet and may have up to 12,000 feet of bridged tap and up to 2800 ohms of resistance. 2.4.2.4 The UCL-D is a designed circuit, is provisioned with a test point, and comes standard with a DLR. OC is a chargeable option for a UCL-D; however, OC is always required on UCLs where a reuse of existing facilities has been requested by Granite. 2.4.2.5 These loops are not intended to support any particular services and may be utilized by Granite to provide a wide-range of telecommunications services so long as those services do not adversely affect BellSouth’s network. This facility will include a Network Interface Device (NID) at the customer’s location for the purpose of connecting the loop to the customer’s inside wire. 2.4.2.6 BellSouth will make available the following UCL-Ds:

  • Unbundled Copper Loop – Non-Designed (UCL-ND 2.4.3.1 The UCL–ND is provisioned as a dedicated 2-wire metallic transmission facility from BellSouth’s Main Distribution Frame (MDF) to a customer’s premises (including the NID). The UCL-ND will be a “dry copper” facility in that it will not have any intervening equipment such as load coils, repeaters, or digital access main lines (DAMLs), and may have up to 6,000 feet of bridged tap between the End User’s premises and the serving wire center. The UCL-ND typically will be 1300 Ohms resistance and in most cases will not exceed 18,000 feet in length, although the UCL-ND will not have a specific length limitation. For Loops less than 18,000 feet and with less than 1300 Ohms resistance, the Loop will provide a voice grade transmission channel suitable for Loop start signaling and the transport of analog voice grade signals. The UCL-ND will not be designed and will not be provisioned with either a DLR or a test point. 2.4.3.2 The UCL-ND facilities may be mechanically assigned using BellSouth’s assignment systems. Therefore, the Loop Makeup (LMU) process is not required to order and provision the UCL-ND. However, CBX One-Stop can request LMU for which additional charges would apply. 2.4.3.3 For an additional charge, BellSouth also will make available Loop Testing so that CBX One-Stop may request further testing on the UCL-ND. Rates for Loop Testing are as set forth in Exhibit A of this Attachment. 2.4.3.4 UCL-ND Loops are not intended to support any particular service and may be utilized by CBX One-Stop to provide a wide-range of telecommunications services as long as those services do not adversely affect BellSouth’s network. The UCL- ND will include a NID at the customer’s location for the purpose of connecting the Loop to the customer’s inside wire. 2.4.3.5 OC will be provided as a chargeable option and may be utilized when the UCL-ND provisioning is associated with the reuse of BellSouth facilities. OC-TS does not apply to this product. 2.4.3.6 CBX One-Stop may use BellSouth’s Unbundled Loop Modification (ULM) offering to remove excessive bridged taps and/or load coils from any copper Loop within the BellSouth network. Therefore, some Loops that would not qualify as UCL-ND could be transformed into Loops that do qualify, using the ULM process.

  • Hepatitis B Vaccine Where the Hospital identifies high risk areas where employees are exposed to Hepatitis B, the Hospital will provide, at no cost to the employees, a Hepatitis B vaccine.
