Some embodiments provide novel methods for performing services for machines operating in one or more datacenters. For instance, for a group of related guest machines (e.g., a group of tenant machines), some embodiments define two different forwarding planes: (1) a guest forwarding plane and (2) a service forwarding plane. The guest forwarding plane connects to the machines in the group and performs L2 and/or L3 forwarding for these machines. The service forwarding plane (1) connects to the service nodes that perform services on data messages sent to and from these machines, and (2) forwards these data messages to the service nodes. In some embodiments, the guest machines do not connect directly with the service forwarding plane. For instance, in some embodiments, each forwarding plane connects to a machine or service node through a port that receives data messages from, or supplies data messages to, the machine or service node.

Ion chromatography system and methods utilizing a weak acid or weak base extraction device
A permeative amine/acid introduction device (PAID) is placed after a conventional KOH eluent suppressed conductometric anion chromatography (SCAC) system. The PAID converts the suppressed eluites from the acid form to the corresponding salt. For example, when the analytes are acids, they are converted to the corresponding ammonium salt (NR2H+HX→NR2H2++X−) and allows very weak acids HX (pKa≥7.0) that cannot normally be detected by SCAC to be measured by a second conductivity detector following the PAID. Permeative reagent introduction is dilutionless, can be operated without pumps and provides good mixing with low band dispersion (as small as 30 μL). An exemplary amine is diethylamine (DEA), which was chosen as the amine source due to its low pKb value (pKb 3.0), high vapor pressure, and low toxicity and low odor. |

Method and a machine for of making tissue paper
The invention relates to a method of making tissue paper in a machine for making tissue paper and in which method a fibrous web is passed through at least one press nip together with a texturing belt. The texturing belt has a side that faces the fibrous web in the press nip and the surface of that side is a web contacting surface that is textured. The texturing belt can be selected such that the tissue paper that is manufactured obtains desired values for one or several parameters. The invention also relates to a machine for making tissue paper. The machine comprises a forming section, a drying cylinder, a press having a first press unit and a second press unit between which press units a nip is formed. The second press unit is preferably a shoe roll. The machine also comprises a drying cylinder which is arranged to be heated from the inside by hot steam and on which a fibrous web can be dried by heat. A texturing belt is arranged to run in a loop through the nip and to the drying cylinder such that a fibrous web can be carried by the texturing belt to the drying cylinder and transferred to the drying cylinder. The side of the texturing belt that contacts the fibrous web comprises a layer of a polymer material such that the polymer material will contact the fibrous web and cavities are formed in that surface of the texturing belt that comes into contact with the fibrous web. |
