Joint and reverse templates are used to mark straight joints and check return moulds, respectively. Face templates mark faces without mouldings, such as on arch stones, while bed templates mark mouldings on top and bottom beds of stones like columns. Cover templates indicate moulds that do not run the full length of the stone. Wrap around templates are for curved surfaces. Raking/stretch templates are used for moulds applied to sloped joints which stretch the template from the original.
Squares, steel rules, scribers, steel dividers, and beam compasses are essential measuring and marking tools for creating templates. Squares ensure perpendicular lines while steel rules offer accuracy. Scribers score sheet metal and dividers mark curves. Beam compasses reach larger radii. Snips remove waste but files accurately reduce templates to working lines using various shapes and sizes of files. Steel wool and permanent markers provide finishing touches by cleaning and clearly marking templates.
The document provides instructions for constructing a regular pentagon using basic geometric techniques:
1) Mark a circle with center point C and diameter line AB. Mark a perpendicular line DC and point E to form a second circle.

This document provides descriptions of various surface finishes used in stonemasonry. It describes finishes such as plane faced and broached, which involve chiseling and polishing stone to remove marks. It also outlines dabbed and sparrowpecked finishes involving indentations made in patterns. Tooled and chevroned finishes are produced using chisels at angles. Bull-faced and split-faced finishes give the impression of a split stone. More intricate finishes like reticulated and vermiculated involve sinking shapes into the stone. Hammer dressing combines dabbing and a rough appearance. The finishes are used for architectural features like ashlar stonework.
This presentation provides step-by-step instructions for constructing a snecked rubble wall with angled internal and external returns. The bonding pattern depends on having stones of certain lengths, so the exact wall may not be replicable, but a similar arrangement should be possible. The goal is to instruct stonemasons on building this type of structured rubble wall.
The document provides a step-by-step guide for constructing a snecked rubble wall with a block backing. It explains that the first course uses a repeating pattern of one riser followed by three levellers. Subsequent courses consist of arrangements built between the risers of the lower courses, with a sneck followed by a riser and two levellers. As the wall is built higher, the same bonding pattern is maintained while ensuring proper overlaps and joints between stones. Finishing steps include leveling the top course and pointing the completed wall.

It explains that the number of courses for a given height can be determined using a brick dimension table. The number of bricks for a given length is also found using this table. Additionally, it notes that every square meter of half brick walling contains 60 bricks, so the total number of bricks for a wall can be calculated by multiplying the surface area by 60. Three example calculations are provided to demonstrate this process.
This document provides instructions for stonemasons on how to cut different types of mouldings, including cavetto mouldings and return moulds. It explains how to identify the elements of a cavetto moulding, set out a template to mark the moulding, and cut the moulding using chisels. It also describes how to mark and cut mitres, splays, and return moulds. The goal is to teach stonemasons the proper techniques for shaping stone to create decorative mouldings.
Sedimentary rock is formed from the compaction and lithification of layers of sediment over millions of years. Sandstone forms from quartz and feldspar minerals in sediment, and limestone forms from calcium carbonate from marine organisms. Igneous rock forms when magma cools and solidifies, such as granite. Metamorphic rock forms from the alteration of sedimentary or igneous rock under heat and pressure, changing the rock type, such as slate forming from shale and marble from limestone. Stone should be laid according to its natural bedding plane for maximum strength, or on its edge for overhanging features.
This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

A mitre is the term used to describe the arris formed when adjacent mouldings
intersect. There are both external and internal mitres.
EXTERNAL MITRE MITRE BLOCKS STEEL SQUARES
There are two common methods of marking a mitre line; using mitre blocks and
using two steel squares. The mitre block method is often easier but a stonemason is
more likely to carry the squares in their toolkit. Your course tutor will demonstrate
each method in the workshop.
