Barrel and Overall Length Measuring Procedure
TENNESSEE BUREAU OF INVESTIGATION Forensic Services Division Firearms/Toolmarks Standard Operating Procedures Manual Barrel and Overall Length Measuring Procedure 7.0 BARREL AND OVERALL LENGTH MEASURING PROCEDURE 7.1 Scope: One of the routine procedures conducted in a firearm examination is determining the barrel length and overall length of the firearm. 7.2 Precautions/Limitations: Accuracy is imperative to this examination. It is vitally important that the firearm examiner use calibrated measuring devices, or instruments checked against calibrated measuring devices. These measuring devices will be checked against a NIST traceable ruler prior to being placed into service. Also, care shall be taken if any object is placed down the barrel to help expedite the barrel length measurement. Only a non-marring item should be placed down the barrel. Test firing of the firearm should be performed prior to placing any item down the barrel if possible. TCA Section 39-17-1301 defines a short-barreled rifle and shotgun as having a barrel length of less than sixteen inches (16") for a rifle and eighteen inches (18") for a shotgun, or an overall firearm length of less than twenty-six inches (26"). TCA Section 39-17-1302 classifies those as prohibited weapons.

Jodhpur-NH73 INDIA ABSTRACT: Surveying is the branch of civil engineering which deals with measurement of relative positions of an object on earth’s surface by measuring the horizontal distances, elevations, directions, and angles. Surveying is typically used to locate and measure property lines; to lay out buildings, bridges, channels, highways, sewers, and pipelines for construction; to locate stations for launching and tracking satellites; and to obtain topographic information for mapping and charting. It is generally classified into two categories: Plane surveying (for smaller areas) and Geodetic surveying (for very large areas). Surveying is the art of making suitable measurements in horizontal or vertical planes. This is one of the important subjects of civil engineering. Without taking a survey of the plot where the construction is to be carried out, the work cannot begin. Dalhousie provides all type of location in a platform . Key Words : 1.Surveying -

Founded in 1906 by innovative young engineer, Frank Moore, Moore & Wright has been designing, manufacturing and supplying precision measuring equipment to global industry for over 100 years. With roots fixed firmly in Sheffield, England, the company began by manufacturing a range of calipers, screwdrivers, punches and other engineer’s tools. Following investment from Mrs Wright, a shrewd Sheffield businesswoman, Frank was able to expand the business and further develop his innovative designs. By the mid-nineteen twenties, thanks to the company’s enviable reputation, Moore & Wright was approached by the UK Government to consider manufacturing a range of quality micrometers. It was in this field that Moore & Wright’s status as UK agent for the Swiss Avia range of products and subsequent acquisition of the Avia brand and manufacturing rights, proved invaluable. -

Procedure for Adult Height
NIHR Southampton Biomedical Research Centre The NIHR Southampton Biomedical Research Centre (BRC) has a tight quality assurance system for the writing, reviewing and updating of Standard Operating Procedures. As such, version-controlled and QA authorised Standard Operating Procedures are internal to the BRC. The Standard Operating Procedure from which information in this document has been extracted, is a version controlled document, managed within a Quality Management System. However, extracts that document the technical aspects can be made more widely available. Standard Operating Procedures are more than a set of detailed instructions; they also provide a necessary record of their origination, amendment and usage within the setting in which they are used. They are an important component of any Quality Assurance Framework, but in themselves are insufficient and need to be used and interpreted with care. Alongside the extracts from our Standard Operating Procedures, we have also made available here an example Standard Operating Procedure and a word version of a Standard Operating Procedure template. Using the example and the Standard Operating Procedure template, institutions can generate their own Standard Operating Procedures and customise them, in line with their own institutions. Simply offering a list of instructions to follow does not assure that the user is able to generate a value that is either accurate or precise so here in the BRC we require that Standard Operating Procedures are accompanied by face-to-face training. This is provided by someone with a qualification in the area or by someone with extensive experience in making the measurements. Training is followed by a short competency assessment and performance is monitored and maintained using annual refresher sessions. -

Kaufmann1 and E. George Robison2,3 In the broad sense, physical habitat in streams includes all those physical attributes that influence or provide sustenance to organisms within the stream. Stream physical habitat varies naturally, as do biological characteristics; thus, expectations differ even in the absence of anthropogenic disturbance. Within a given physiographic-climatic region, stream drainage area and overall stream gradient are likely to be strong natural determi- nants of many aspects of stream habitat, because of their influence on discharge, flood stage, and stream power (the product of discharge times gradient). Summarizing the habitat results of a workshop conducted by EMAP on stream monitoring design, Kaufmann (1993) identified seven general physical habitat attributes important in influencing stream ecology: ! Channel Dimensions ! Channel Gradient ! Channel Substrate Size and Type ! Habitat Complexity and Cover ! Riparian Vegetation Cover and Structure ! Anthropogenic Alterations ! Channel-Riparian Interaction All of these attributes may be directly or indirectly altered by anthropogenic activities. -
2.3. DEVELOPMENT of DESIGN 2.3.1. Surveying Surveying Is The
2.3. DEVELOPMENT OF DESIGN 2.3.1. Surveying Surveying is the technique and science of accurately determining the terrestrial or 3D space position of points and the distances and angles between them. These points are usually, but not exclusively, associated with positions on the surface of the Earth, and are often used to establish land maps and boundaries for ownership or governmental purposes. In order to accomplish their objective, surveyors use elements of geometry of engineering, mathematics, physics, and law. Surveying has been an essential element in the development of the human environment since the beginning of recorded history (ca. 5000 years ago) and it is a requirement in the planning and execution of nearly every form of construction. Its most familiar modern uses are in the fields of transport, building and construction, communications, mapping, and the definition of legal boundaries for land ownership. Method Historically, angles and distances were measured using a variety of means, such as chains with links of a known length, for instance a Gunter's Chain, or measuring tapes made of steel or invar. In order to measure horizontal distances, these chains or tapes would be pulled taut, to reduce sagging and slack. Additionally, attempts to hold the measuring instrument level would be made. In instances of measuring up a slope, the surveyor might have to "break" the measurement- that is, raise the rear part of the tape upward, plumb from where the last measurement ended. Historically, horizontal angles were measured using a compass, which would provide a magnetic bearing, from which deflections could be measured. -
Determining Slope 3Notes
DETERMINING SLOPE 3NOTES OBJECTIVES The purpose of this chapter is to: • Measure slope. • Calculate percent slope. • Understand the different locations that slope may be measured from. Slope What is slope? Slope is the change in elevation, measured in consistent units, from one point to another. Why would slope be a factor in evaluating a site for an onlot sewage disposal system? DRevisedETERMINING 5/12 SLOPE 3-1 How To Measure Slope Slope must be measured perpendicular to the contours of the land. Contours are lines of equal NOTES elevation. There are two ways to measure slope: 1) By taking field measurements and dividing the vertical distance by the horizontal distance (rise ÷ run), and then multiplying by 100 for percent slope. 2) By measuring the angle with an instrument. 3-2 DETERMINING SLOPE 1) VERTICAL AND HORIZONTAL DISTANCES Slope can be calculated by using the rise over run method of dividing the vertical distance by NOTES the horizontal distance. Multiply the answer you get by 100 to get percent slope. vertical distance ÷ horizontal distance = slope RUN RISE DETERMINING SLOPE 3-3 SAMPLE PROBLEM Solve for the percent slope. Round to the nearest whole percent. NOTES Vertical distance is 6 feet 8 inches and horizontal distance is 38 feet. Percent slope = ________ EXERCISE 3-1 Solve for the percent slope. Round to the nearest whole percent. 1) Vertical distance is 5 feet and horizontal distance is 57 feet.

Using a Scale Ruler;
Using a Scale Ruler; What is Scale and why do we use it. Designers and Architects use ‘scale’ so they can draw on paper a small replica of the real space, building or layout as it will be when built, but in miniature, so that everything is in proportion and you can carry the drawings around and work on them. There are different scales you can use giving you larger scale drawings or small scale. An example of this is if you look at the Deeds of your house you should find a ‘site location plan to scale’ at possibly 1:500. It just shows the outline of your property in relation to other buildings and roads etc It does not show detail of the building but … will show out-houses or drive ways. It also has a red line around your boundary which confirms the land your property will occupy and forms part of your contract on purchase. Architects will often use a scale of 1:100 to draw up an outline of a new building and it will show details of how the property is divided up into rooms, stairs entrances and different floor levels. Using the scale of 1:50 you can put a lot more detail in, showing basic furniture layouts within the rooms and identifying bathrooms and kitchens with fitted units shown and changes of ceiling height, floor levels and is often used for planning applications with a site plan or a plan at 1:100 depending on the type of application and the details required. -
