Connecting reconnecting

Electronic Connectors. The complexity and size of many electronic systems necessitate constmction from relatively small building blocks which ate then assembled with connectors. An electronic connector is a separable electrical connector used in telecommunications apparatus, computers, and in signal transmission and current transmission <5 A. Separable connectors ate favored over permanent or hard-wired connections because the former facilitate the manufacture of electronic systems also, connectors permit assemblies to be easily demounted and reconnected when inspection, replacement, or addition of new parts is called for. 

Constructability can be less of a problem with shells. The logistics of conventional reinforcement schemes with alternative upgrade options can be quite difficult. Reinforcing connections and bracing may require temporary supports of the members being reconnected. Access to the critical joints for reinforcement can sometimes be virtually impossible. 

Occluded IV catheter. Disconnect IV tubing from catheter attach a 1 -ml TB syringe with 5,000 U urokinase to catheter inject urokinase slowly (equal to volume of catheter). Connect empty 5-ml syringe aspirate residual clot. When patency is restored, irrigate with 0.9% NaCl reconnect IV tubing to catheter. 

Reconnect the rest of the apparatus to the flotation chamber and add more distilled water to bring to the already determined total solution volume. Connect to the flow-meter and begin stirring the flotation chamber. 

Disconnect the outlet tubing from the saline reservoir (connected to the Pasteur pipet), and reconnect it to the medium reservoir (again to tubing attached to the Pasteur pipet). The circuit is now complete... 

Upon dissection of the nervus ischiadicus of the rat and subsequent reconnection by a typical microsurgical suture, a protective cover (cuff) of BASYC prevents connective tissue from growing into the nerve gap and favors the ad-... 

With your models, construct a pair of enantiomers. From each of the models, remove the same common element (e.g., the white component) and the connecting links (bonds). Reconnect the two central carbons by a bond. What you have constructed is the meso form of a molecule, such as meso-tartaric acid. How many chiral carbons are there in this compound (5a) ... 

Assay Preparation Transfer about 4 g of sample, accurately weighed, into a 250-mL Erlenmeyer flask, and add 80 mL of 0.5 N potassium hydroxide and 0.5 mL of phenolphtha-lein TS. Connect an air condenser at least 65 cm long to the flask, and heat the mixture on a hot plate for about 2.5 h. Remove the air condenser and add approximately 10% phosphoric acid to the hot mixture until it is definitely acid to Congo red test paper. Reconnect the air condenser, and heat until the fatty acids are liquified and clear. Cool, and transfer the mixture into a 250-mL separator with the aid of small portions of water and hexane. Extract the liberated fatty acids with three successive 25-mL portions of hexane, and collect the extracts in a second separator. Wash the combined hexane extracts with two 25-mL portions of water, and add the washings to the separator containing the water layer. Retain the combined hexane extracts for the determination of total fatty acids. Transfer the contents of the first separator to a 250-mL beaker, heat on a steam bath to remove traces of hexane, filter through acid-washed, fine-texture filter paper into a 500-mL volumetric flask, and finally dilute to volume with water (Solution I). Pipet 25.0 mL of this solution into a 100-mL volumetric flask, and dilute to volume with water (Solution II). Retain the rest of Solution I for the determination of Glycerin (below).
