Abstract: A method for treating or pre-treating parts, profiled-pieces, strips, sheet metals or wires having metallic surfaces, in which at least 5% of these surfaces consists of aluminum or of at least one aluminum alloy with an acid aqueous solution which contains fluoride, zinc and phosphate and which has the following dissolved contents in the phosphatizing solution: sodium virtually none, from 0.04 to less than 2 g/L; potassium virtually none or in a concentration ranging from 0.025 to 2.5 g/L; sodium and potassium in a concentration ranging from 0.025 to 2.5 g/L as sodium, whereby the potassium content is converted to sodium on a molar basis; zinc 0.2 to 4 g/L zinc, 5 to 65 g/L calculated as PO4; 0.03 to 0.5 g/L phosphate free fluoride wherein the total fluoride is present in a concentration ranging from 0.1 to 5 g/L. A zinc-containing phosphate layer is thereby deposited onto the metallic surfaces with a layer weight ranging from 0.5 to 10 g/m2.

Abstract: Various embodiments of systems and methods for lifecycle stable user interface adaptations are described herein. All adaptations done by partners/key users/end users to a user interface of a computer software application are preserved during the lifecycle of the application. In one aspect, the adaptations are persisted as additional metadata used for the generation of the user interface. In another aspect, the lifecycle stability is achieved by attaching the adaptations to semantically coherent set of fields placed in the UI that reappear in future releases of the computer software application.

Abstract: In an aspect there is provided a method. The method may include providing, at a repository, storage for a plurality of tenants, providing a plurality of layers, and providing a plurality of versions; and separating, based on the plurality of layers and the plurality of versions, data for each of the plurality of tenants, wherein during runtime one of the plurality of tenants corresponds to the plurality of layers and one of the plurality of versions. Related apparatus, systems, techniques and articles are also described.

Abstract: Transporting of flexibility changes of customer content between tenants in a multi-tenant computing system can be performed by exporting customer content from a first tenant of the multi-tenant computing system, transporting the customer content exported from the first tenant to a second tenant of the multi-tenant computing system, importing the customer content into a staging area in the second tenant to enable a user associated with second tenant to access the customer content via the staging area based on a content extraction trigger, and activating selected customer content from the staging area in a productive component of the second tenant. The content extraction trigger can characterize an extraction of at least some of the customer content from the staging area. Related methods, systems, and articles of manufacture are also disclosed.

A zinc-containing phosphate layer is thereby deposited onto the metallic surfaces with a layer weight ranging from 0.5 to 10 g/m2.

Abstract: A method for the treatment or pre-treatment of surfaces of metal objects by means of an acidic, aqueous solution containing zinc and phosphate. The phosphating solution contains between 0.1-10 g/L, zinc, 4-50 g/L phosphate calculated as PO4, between 0.03-3 g/L, of at least one guanidine compound comprising at least one nitro group calculated as nitroguanidine, and between 0.001-0.9 g/L hydrogen peroxide and has a temperature of less than 80° C. The corresponding acidic, aqueous composition and finished products are also disclosed.

Abstract: In some example embodiments, a computerized method includes determining at least one of a read frequency, a write frequency and a data volume for data persistently stored. The data has a first format. The method also includes selecting a first type of data migration or a second type of data migration, wherein the selecting is derived from at least one of the read frequency, the write frequency and the data volume for the data persistently stored. The method includes transforming the data to a second format using the selected data migration. The method includes outputting the data for storage in machine-readable medium.
