In testing a component-set whole process which includes a plurality of components and in which the order of execution of the plurality of components is defined, a computer system exports, to a storage resource, an input package for at least one component to be executed. Each of the plurality of components is a module of a significant process as a set of one or more processing steps and independent of any other components. Each input package includes an input value of a component that corresponds to the input package. The computer system imports an exported input package of a component to be debugged into the component to be debugged in order to execute the component to be debugged, without executing a component the order of which precedes the order N (where N is a natural number) of the component to be debugged.

Method for assisting with debugging, and computer system

An operation content evaluation system for evaluating an operation content for controlling computer resources, the operation content evaluation system including: a content site including a content management server for distributing operation contents for controlling computer resources; and a user site including a content evaluation server for evaluating one of the operation contents and computer resources, wherein the content management server holds catalogs associated one-to-one with the operation contents and each of the catalogs includes prerequisites for executing an operation content and evaluation elements for the operation content, wherein the content evaluation server holds configuration information collected from the computer resources in resource management information, and wherein the content evaluation server acquires the catalogs from the content management server, selects a catalog associated with the operation content to be evaluated from the catalogs, and evaluates the operation content by comparing the selected catalog with the resource management information.

Operation content evaluation system and storage medium

The present invention is intended to provide a metal scavenger that is free from the defects of metal scavengers formed by introducing dithioic acid groups to polyalkylenepolyamines or the like, is high in settling speed of flock when used in waste water treatment, and can carry out treatment of waste water efficiently and also to provide a process of producing the same efficiently. The present metal scavenger has a structure that is formed by replacing the hydrogen atoms linked to the nitrogen atoms of a polyamine having aminomethyl groups by dithioic acid groups or their salts and that is represented by the following general formula: ##STR1## wherein R represents a dithioic acid group, an alkali metal dithioate group, an alkaline earth metal dithioate group, or an ammonium dithioate group and R' represents a hydrogen atom, a dithioic acid group, an alkali metal dithioate group, an alkaline earth metal dithioate group, or an ammonium dithioate group. The present metal scavenger can be obtained by causing carbon disulfide to act on a polyamine having aminomethyl groups or by polymerizing a monomer having the following formula: ##STR2## wherein R represents a dithioic acid group, an alkali metal dithioate group, an alkaline earth metal dithioate group, or an ammonium dithioate group and R' represents a hydrogen atom, a dithioic acid group, an alkali metal dithioate group, an alkaline earth metal dithioate group, or an ammonium dithioate group.

Metal scavengers and processes for the production thereof

Metal scavengers suitable for use in the treatment of waste water are disclosed. The metal scavengers individually comprise a polyamine derivative and a polyethyleneimine derivative. The polyamine derivative is formed of a polyamine having a molecular weight not higher than 500 and contains, per molecule of the polyamine, at least one dithiocarboxyl group or a salt thereof as an N-substituting group substituted for an active hydrogen atom of the polyamine such that at least 30% of suitable active hydrogen atoms contained in the polyamine are substituted by the dithiocarboxyl group or salt thereof. The polyethyleneimine derivative is formed from a polyethyleneimine having an average molecular weight of at least 5,000 and contains, per molecule of the polyethyleneimine, at least one dithiocarboxyl group or a salt thereof as an N-substituting group substituted for an active hydrogen atom of the polyethyleneimine such that at least 40% of substitutable active hydrogen atoms contained in the polyethyleneimine are substituted by the dicarboxyl group or a salt thereof. The mixing ratio of the polyamine derivative to the polyethyleneimine derivative is about 9-7:1-3 by weight.

Metal scavengers for treating waste water

A process for the treatment of contaminants using metal scavenger is disclosed. The metal scavengers individually comprise a polyamine derivative and a polyethyleneimine derivative. The polyamine derivative is formed of a polyamine having a molecular weight not higher than 500 and contains, per molecule of the polyamine, at least one dithiocarboxyl group or a salt thereof as an N-substituting group substituted for an active hydrogen atom of the polyamine. The polyethyleneimine derivative is formed from a polyethyleneimine having an average molecular weight of at least 5,000 and contains, per molecule of the polyethyleneimine, at least one dithiocarboxyl group or a salt thereof as an N-substituting group substituted for an active hydrogen atom of the polyethyleneimine.
