The cause and effect diagram is an easy yet powerful tool commonly used in a cross functional setting to visually describe the potential root causes for a specific problem in question.
The tool lends itself to enabling a team to readily organize the causes behind the problem into useful categories, providing a structured brainstorming session.
One of the seven basic quality tools, the cause and effect diagram is also know as the fishbone diagram as the key causes look like the bones of a fish when displayed visually, hence the name and the Ishikawa diagram named after Kaoru Ishikawa, who first proposed the tool.
Variations of this method include the cause enumeration diagram, the cause and effect diagram with the addition of cards CEDACand a desired-result fishbone diagram. Define the problem effect to be solved. This first step is probably one of the most important tasks in building a cause and effect diagram.
While defining your problem or event, your problem statement may also contain information about the location and time of the event. On the cause and effect diagram the problem is visually represented by drawing a horizontal line with a box enclosing the description of the problem on the tip of the arrow. Identify the key causes of the problem or event. In this step, the primary causes of the problem are drilled down by using brainstorming techniques.
Often these causes are categorized under people, equipment, materials, external factors, etc. Other appropriate primary causes include service, quality, technology, consumables, work processes, environment, service level, etc. The image below shows how to visually depict these key causes on the cause and effect diagram.Ableton sample rate latency
Identify the reasons behind the key causes. The goal in this step is to brainstorm as many causes for each of the key causes.
Tools such as the 5 Whys the subject of a future column can help your team to drill down to these sub-causes. To facilitate participation from all of your team members, ask each member of the group to provide one reason behind a key cause. These suggestions should be written down and connected to their appropriate key cause arrow see the image below. Remember that these reasons are free- flowing, form logical patterns, and are inter-connected to a key cause.
Identify the most likely causes. At the end of step three, your team should have a good overview of the possible causes for the problem or event; if there are areas in the chart where possible causes are few, see if your team can dig deeper to find more potential causes. The team then should focus more specifically on the potential cause s that have a high probability of taking place. It is not unusual for teams to use techniques such as multi-voting to shortlist the areas that will have lasting impact on solving the problem at hand.
In certain instances, the team might collect additional data to better understand and quantify the potential causes. Simple hypothesis testing — such as asking "Where? How to Get the Most Out of the Cause and Effect Diagram One of the key pitfalls to watch for when completing a cause and effect diagram is to avoid getting into the habit of providing never ending possible causes to the problem.
A good facilitation tip in this situation is to decide when to stop the cause and effect discussion by focusing the team on their "span-of-control" and "sphere-of-influence. The sphere of influence refers to the work areas where the team is able to exert some influence but not full control. For teams to come up with meaningful solutions, they should operate in both these work areas.
Other helpful tips to ensure the effectiveness of the cause and effect diagram is to have an experienced facilitator. A Healthcare Cause and Effect Diagram Example As I mentioned in an earlier column, hand hygiene compliance in a healthcare setting is less than optimal in most hospitals, with over 90, deaths attributed to hospital acquired infections every year in the United States.
In the Mayo Clinic, one of its teams used the cause and effect diagram to identify the various potential causes of improper hand hygiene in the health care setting. The team then conducted a quick assessment to determine how often the potential causes occurred. Based on this data, the team then implemented a multi-pronged pilot to increase awareness, accessibility and accountability, and to initiate other specific interventions, resulting in sustained improvements in hand hygiene compliance in the pilot units.Pmfby 2019

Trees provide us with fresh air, shade in summers, food, and other benefits without which we cannot even think of living. One of the most principal organs of a tree is a leaf.
The leaves are the organs for photosynthesis - a process when carbon dioxide is turned into oxygen. The structures of leaves are adapted for efficient photosynthesis. Most leaves are broad and so have a large surface area allowing them to absorb more light. Also, they are thin, which means a short distance for carbon dioxide to diffuse in and oxygen to diffuse out easily. The blade is the broad, flat part of the leaf.
Photosynthesis occurs in the blade, which has many green food-making cells. If you look closer at leaves, you will notice networks of thin threads. Those networks are called veins : they support the structure of the leaf and transport substances to and from the cells in the leaf. The main vein of a leaf, running down the centre of the leaf, is called midrib. Those networks are called veins.
The area of some plants that connects the plant's stem and leaf is called the petiole. Writing correction.
Leaves' structure Plants play a very important role in our surroundings. The petiole is the pipeline through which the products of photosynthesis are moved from individual leaves to the rest of a plant and through which necessary chemicals and nutrients from other parts of the plant are brought to individual leave.
All rights reserved.Of the several kinds of Carnations, the three most common are the annual carnationsborder carnations and perpetual-flowering carnations. Carnations are also commonly referred to by their scientific name, " Dianthus ", the name given by the Greek botanist Theopharastus. Carnations got the name Dianthus from two Greek Words - "dios", referring to the god Zeus, and "anthos", meaning flower. Carnations are thus known as the " The Flowers of God ".Finding Mean, Median, Range, \u0026 IQR with a Stem \u0026 Leaf
Another reason why carnations have become popular is because they come in numerous colors and each color of carnation has a different meaning. Some of these meanings are listed below.
It is a good idea to check the meaning of the particular color or type of carnation before you gift them to someone. The single flowers of the Carnations species, Dianthus caryophyllus have 5 petals and vary from white to pink to purple in color. Border Carnation cultivars may have double flowers with as many as 40 petals. When grown in gardens, Carnations grow to between 6 and 8.
Petals on Carnations are generally clawed or serrated. Carnations are bisexual flowers and bloom simply or in a branched or forked cluster. The stamens on Carnations can occur in one or two whorls, in equal number or twice the number of the petals. The Carnation leaves are narrow and stalk less and their color varies from green to grey-blue or purple. Carnations grow big, full blooms on strong, straight stems.

According to a Christian legend, Carnations first appeared on earth as Jesus carried the Cross. Carnations sprang up from where the Virgin Mary's tears fell as she cried over her son's plight.In geometry, a circle is a closed curve formed by a set of points on a plane that are the same distance from its center O.
That distance is known as the radius of the circle. The diameter of a circle is a line segment that passes through the center of the circle and has its endpoints on the circle.
All the diameters of the same circle have the same length. A chord is a line segment with both endpoints on the circle. The diameter is a special chord that passes through the center of the circle. The diameter would be the longest chord in the circle. The radius of the circle is a line segment from the center of the circle to a point on the circle. The plural of radius is radii. The radii of a circle are all the same length. The radius is half the length of the diameter. Tangent A tangent is a line that touches a circle at only one point.
A tangent is perpendicular to the radius at the point of contact.Khs gravel bike
The point of tangency is where a tangent line touches the circle. It touches the circle at point B and is perpendicular to the radius. Point B is called the point of tangency. Parts of a Circle The following video gives the definitions of a circle, a radius, a chord, a diameter, secant, secant line, tangent, congruent circles, concentric circles, and intersecting circles. A secant line intersects the circle in two points. A tangent is a line that intersects the circle at one point.
A point of tangency is where a tangent line touches or intersects the circle. Congruent circles are circles that have the same radius but different centers. Concentric circles are two circles that have the same center, but a different radii. Intersecting Circles : Two circles may intersect at two points or at one point.
If they intersect at one point then they can either be externally tangent or internally tangent. Two circles that do not intersect can either have a common external tangent or common internal tangent. In the common external tangentthe tangent does not cross between the two circles. In the common internal tangentthe tangent crosses between the two circles.

The leaves are the primary photosynthetic organs of plants, serving as key sites where energy from light is converted into chemical energy. Similar to the other organs of a plant, a leaf is comprised of three basic tissue systems, including the dermalvascularand ground tissue systems.
Circle: Diameter, chord, radius, arc, tangent
These three motifs are continuous throughout an entire plant, but their properties vary significantly based upon the organ type in which they are located. All three tissue systems are illustrated in Figure 1, which is a cutaway drawing of a typical leaf. The dermal tissue of a plant, more specifically referred to as the epidermisis an outer protective layer of typically polygonal cells, which helps defend against injury and invasion by foreign organisms.
The epidermis of the leaf also functions in a more specialized manner by secreting a waxy substance that forms a coating, termed the cuticleon the surface of the leaf. An adaptation unique to terrestrial plants, the cuticle functions chiefly in the retention of water. As presented in Figure 1, the cells that comprise the epidermis of a leaf are arranged very tightly together in a single stratum. Microscopic pores known as stomata are the only breaches in the otherwise continuous layer of the leaf epidermis.
Each individual pore, or stoma, is, in fact, a small opening between a pair of specialized cells known as guard cells. By modifying the size of the stomata, guard cells are able to regulate gas exchange and transpiration.
Such modifications are influenced by various environmental factors. For example, when the weather is unusually hot and dry, the guard cells of plants in danger of losing too much water narrow the stomata width in order to reduce evaporation from the leaf interior.
In order for leaves to obtain water and minerals from the roots and for food manufactured in mature leaves to be transported to the roots and other nonphotosynthetic regions, each leaf must be connected to the overall vascular structure of the plant. Accordingly, the main vascular bundle of xylem and phloem present in the stem of a plant bifurcates into leaf traceswhich are branches of vascular tissue that supply leaves.
Each leaf trace further branches into the familiar veins that can often be seen along the surface of leaves, and the veins repeatedly subdivide as well. The vascular components, which serve as a basic skeletal structure in addition to functioning in the transport of materials, extend throughout the mesophyll so that the xylem and phloem are brought into propinquity with leaf tissues that carry out photosynthesis.
The mesophyll is the mid-section of a leaf, located between the upper and lower epidermal layers. Not only is vasculature found in the mesophyll, but also the ground tissue of a leaf. Ground tissue comprises the bulk of a plant leaf and is generally comprised of a variety of cell types, the predominant of which are parenchyma. The parenchyma cells present in leaves contain chloroplasts, which are the sites of photosynthesis.
In Figure 1, the mesophyll is divided into two conspicuously different regions, a characteristic common among the leaves of many dicotyledons.

The upper section is termed the palisade parenchyma and consists chiefly of elongated columnar parenchyma cells that contain three to five times the number of chloroplasts as the cells that comprise the lower layer, known as the spongy parenchyma. The cells of the spongy parenchyma are irregularly shaped, allowing gases to circulate through the numerous air spaces between them to the palisade parenchyma.
The stomata, which are particularly important for gas exchange, tend to be surrounded by exceptionally large air spaces.Botanists and foresters have developed terms for the patterns and shapes used in tree identification. Some tree species make things more interesting by displaying more than one type of leaf structure. Other species leaves make it nearly impossible to misidentify them because each leaf is unique. This leaf "skin" always has a waxy cover called the cuticle and varies in thickness.
The epidermis may or may not support leaf hairs, which can also be an important botanical identifier. Studying leaf shape and the arrangement of leaves on a stem is the most common way of identifying a tree in the field during the growing season.
The novice taxonomist usually starts with a tree leaf shapewhich is determined by the presence or absence of lobes. One can often name the tree species without using any other identification marker.
These variations are usually easy to deal with by finding a healthy specimen in its natural environment. All tree leaves exhibit margins leaf blade edges that are either serrated or smooth. Leaf margins can be finely classified based on at least a dozen unique characteristics.
There are four major classifications you need to know and into which all others will fit:.
Leaves have unique structures, called veins, that transport liquids and nutrients to leaf cells. Veins also carry the products of photosynthesis back to the rest of the tree.Mikel zelda and chill songs
A tree leaf has several types of veins. The central one is called the midrib or midvein. Other veins connect to the midrib and have their own unique patterns.
Tree leaf veins in dicots we also call these trees hardwoods or deciduous trees are all considered to be net-veined or reticulate-veined. This means that the veins branch from the main rib and then sub-branch into finer veins. There are two classifications you need to know for tree identification:. Share Flipboard Email. Steve Nix.

The Four Steps to Constructing a Cause and Effect Diagram
Definition of a Leaf 2. Parts of a Leaf 3. The leaf is a flattened, lateral outgrowth of the stem in the branch, developing from a node and having a bud in its axil. The leaves take up water and carbon dioxide and convert them into carbohydrates in the presence of sunlight and chlorophyll.
A typical leaf of Ficus religiosa pipal has a broad thin, flat structure called the lamina. The thin stalk below the lamina is the petiole. The lamina possesses a network of veins. The veins have both xylem and phloem elements which are continuous with similar tissues of the stem through those of the petiole.
A strong vein, known as the midrib, runs centrally through the leaf- blade from its base to the apex; this produces thinner lateral veins which in their turn give rise to still thinner veins or veinlets. The lamina is the most important part of the leaf since this is the seat of food manufacture for the whole plant.
Normally two stipules are developed at the base of a leaf petiole; they may be foliaceous, e. Two sessile opposite leaves meeting each other across the stem and fusing together, e. A leaf made up of two or more leaflets, e.
