Hand tools and power tools are used on jobsites and in production facilities to measure, cut, fasten, and form materials. Hand tools include clamps, cutting tools, measuring tools, hammers, screwdrivers, and wrenches. They provide precise control and are used for tasks where power tools are cumbersome or where high amounts of force are not required. Power tools include cordless, corded, hydraulic, and air-powered drills, drivers, impact wrenches, saws, and finishing tools. They are used for tasks that are repeated (such as driving nails in sheetrock) or where high force and speed are required. Measuring and layout tools ensure workpieces are cut to the correct length and angle. Sockets and bits are used with wrenches, screwdrivers, and drills to create holes and drive fasteners. Tool tethers, balancers, and retractors secure tools to keep them close at hand when needed and help prevent injuries caused by dropped tools. Tool storage keeps tools secure and organized for quick access.

No other manufacturer of hand tools and related products used in electrical applications makes more items in America than Klein Tools.
Since 1857, the company operated by Mathias Klein and his descendants to the fifth generation, has grown and developed along with the telecommunications and electrical industries where Klein pliers first found major usages.
Today, Klein Tools, Inc. represents much more than Klein pliers. The company's product line has broadened to include virtually every major type of hand tool used in construction, electronics, mining, and general industry in addition to the electrical and telecommunications fields.
Below is a complete listing of all tools developed by GHG Protocol. Our tools enable companies to develop comprehensive and reliable inventories of their GHG emissions. Each tool reflects best-practice methods that have been extensively tested by industry experts. Many tools are accompanied by a PDF guidance document, which provides step-by-step guidance on the use of a tool and should be consulted first. Most companies will need to apply more than one tool to cover their emissions.
These tools are applicable to many industries and businesses regardless of sector.
Note: International emission factors for electricity use are no longer available from the GHGP website and can be purchased from the IEA.
The RAC tool calculates the HFC and PFC emissions from the manufacture, servicing, and/or disposal of RAC equipment. The tool offers three methods: A sales based approach for manufacturers and users; a life cycle stage approach for users; and a basic screening approach that is intended to help companies gauge whether or not their emissions merit the use of one of the other, more advanced methods.
The Adipic acid tool allows the N2O emissions from adipic acid production to be estimated. It requires data on the amount of adipic acid produced. The tool also calculates any emissions reductions associated with the use of emissions control technologies.
The Iron and Steel tool provides two different methods for calculating CO2 emissions. One method requires data on the quantities of reducing agents and blast furnace additives used, as well as the quantities of the carbonate fluxes introduced into the furnace. The alternative method requires data on the amount of iron or steel produced, as well as of the carbonate fluxes. The emissions calculation from either method can be adjusted to account for the export of carbon-bearing byproducts.
The Nitric acid tool allows the N2O emissions from nitric acid production to be estimated. It requires data on the amount of nitric acid produced. The tool also calculates any emissions reductions associated with the use of emissions control technologies.
The Pulp and Paper tool offers a collection of tools that cover the emission sources typically associated with a pulp and paper plant. It is a joint product of the International Council of Forest and Paper Associations and the GHG Protocol.
The Semiconductor tool calculates the PFC emissions from semi-conductor wafer production. Required data include the quantities of gas that have been both consumed in wafer production and destroyed using abatement technologies, and the number of wafers produced by size.
We've expanded our Tools and resources sections initially published on our homepage as a "frequently accessed tools and resources" drop down. This new format is now accessible from anywhere on the site
OHDSI offers a wide range of open-source tools to support various data-analytics use cases on observational patient-level data. What these tools have in common is that they can all interact with one or more databases using the Common Data Model (CDM). Furthermore, these tools standardize the analytics for various use cases. Rather than having to start from scratch, an analysis can be implemented by filling in standard templates. This makes performing analyses easier, and also improves reproducibility and transparency. For example, there appear to be a near-infinite number of ways to compute an incidence rate, but these can be specified in the OHDSI tools with a few choices, and anyone making those same choices will compute incidence rates the same way.
HADES (previously the OHDSI METHODS LIBRARY) is a collection of open-source R packages that offer functions which can be used together to perform a complete observational study, starting from data in the CDM, and resulting in estimates and supporting statistics, figures, and tables. The packages interact directly with observational data in the CDM, and can be used simply to provide cross-platform compatibility to completely custom analyses, or can provide advanced standardized analytics for population characterization, population-level effect estimation, and patient-level prediction. HADES supports best practices for use of observational data and observational study design as learned from previous and ongoing research, such as transparency, reproducibility, as well as measuring the operating characteristics of methods in a particular context and subsequent empirical calibration of estimates produced by the methods.
DATA QUALITY DASHBOARD applies a harmonized data quality assessment terminology to data that has been standardized in the OMOP Common Data Model. Where ACHILLES runs characterization analyses to provide an overall visual understanding of a CDM instance, the DQD goes table by table and field by field to quantify the number of records in a CDM that do not conform to the given specifications. In all, over 1,500 checks are performed, each one organized into the Kahn framework. For each check, the result is compared to a threshold whereby a FAIL is considered to be any percentage of violating rows falling above that value.
The Rabbit-in-a-Hat tools that come with the White Rabbit software are specifically designed to support a team of experts in these areas. In a typical setting, the ETL design team sits together in a room, while Rabbit-in-a-Hat is projected on a screen. In a first round, the table-to-table mappings can be collaboratively decided, after which field-to-field mappings can be designed while defining the logic by which values will be transformed.
Rabbit-In-a-Hat is designed to read and display a White Rabbit scan document. White Rabbit generates information about the source data while Rabbit-In-a-Hat uses that information and through a graphical user interface to allow a user to connect source data to tables and columns within the CDM. Rabbit-In-a-Hat generates documentation for the ETL process, it does not generate code to create an ETL.
USAGI is a tool to aid the manual process of creating a code mapping. It can make suggested mappings based on the textual similarity of code descriptions. Usagi allows the user to search for the appropriate target concepts if the automated suggestion is not correct. Finally, the user can indicate which mappings are approved to be used in the ETL. Source codes that need mapping are loaded into Usagi (if the codes are not in English additional translations columns are needed). A term similarity approach is used to connect source codes to vocabulary concepts. However, these code connections need to be manually reviewed and Usagi provides an interface to facilitate that. Usagi will only propose concepts that are marked as standard concepts in the vocabulary.
A tool is an object that can extend an individual's ability to modify features of the surrounding environment or help them accomplish a particular task. Although many animals use simple tools, only human beings, whose use of stone tools dates back hundreds of millennia, have been observed using tools to make other tools.
Early human tools, made of such materials as stone, bone, and wood, were used for the preparation of food, hunting, the manufacture of weapons, and the working of materials to produce clothing and useful artifacts and crafts such as pottery, along with the construction of housing, businesses, infrastructure, and transportation. The development of metalworking made additional types of tools possible. Harnessing energy sources, such as animal power, wind, or steam, allowed increasingly complex tools to produce an even larger range of items, with the Industrial Revolution marking an inflection point in the use of tools. The introduction of widespread automation in the 19th and 20th centuries allowed tools to operate with minimal human supervision, further increasing the productivity of human labor.
