Visual instructions for the installation of electric shepherds. How to make an electric shepherd with your own hands from an ignition coil Do-it-yourself electric fence from wild animals scheme

If the area allocated for pasture is large, then it can be difficult to enclose it all with a fence. And sometimes animals belonging to other owners also come to someone's fields. In all cases, an electric shepherd comes to the rescue.

This device is a tape or wire that is easy to install on a fence or move to another place. The article will discuss how to make the device itself and the generator for the electric shepherd with your own hands.

How does the device affect animals?

Upon contact with such a fence, a current is passed through the body of the animal, which goes into the ground. It is not life-threatening, but a horse, for example, will remember the unpleasant sensations that it received here and will no longer approach such a place.

The switched on device generates and supplies voltage pulses emanating from the fencing wire.

The generator for the electric shepherd organizes a walk that is safe and well controllable. You can simply forget about ropes, chains and similar devices, as well as all the troubles associated with them.

Bundle in store

The generator for the electric shepherd of cattle can be bought in the online store. It comes in both foreign and domestic production. Typically, the kit includes the following components:

• a unit that supplies voltage, powered by a battery or directly through the network;
• woven ribbon (it comes in different colors);
• pegs for insulators;
• the insulators themselves, on which the tape is installed;
• wire for connecting the block and the grounded pin;
• the pin itself.

Instead of buying

Not everyone will want to give personal money for this device. An alternative is the ability to make a generator for the electric shepherd on your own. As can be seen from the kit, any radio amateur can assemble the device.

It is better to purchase the block in the store - it is sold separately. But if there is a circuit for a pulse generator for an electric shepherd, then it is also made at home. Everything else is easily assembled from what is at hand.

Useful handy tools

A device made independently will be the most economical option.

A thin wire for welding is used as an electric fence. And in order for the animals to see it, they pull on an additional ribbon with flaps. You can immediately provide for a wide tape, but you will have to pay for it. True, with the wind it sags, and when wet snow falls, the latter settles and freezes on it, and therefore the conductivity can be reduced.

But for the construction of insulators, you can come up with a lot of tools, for example, a wooden stake with plastic bottles (as self-tapping screws), in which two vertical slots are made and a tape is threaded into them. Or you can just wrap the column with tape. Instead of plastic bottles, some use something else.

Grounding can be implemented using an ordinary piece of reinforcement or an iron rod, a little more than a meter in length. It sinks into the ground about a meter. For best performance, it is good to water the soil in dry weather.

To connect the block, conductor and fence, use the so-called cords with "crocodiles" for cars. They are cut in two.

If you buy columns, then they will cost far from cheap. They usually require a lot, since the maximum distance from each other should be ten meters. But it is desirable to install them even more often. In firms, the posts are made of plastic. Flattering reviews about such devices are extremely problematic to find. They are praised only when the installation is necessary temporary. But for a long-term stationary installation, it is better to use wooden ones made by yourself.

Of course, it will be more difficult to score them. Hammering with a sledgehammer is unlikely to be convenient. And some get out of the situation by first driving in metal corners, and then screwing wooden posts to them. In addition, you can purchase a hand drill and use it instead of driving.

In general, if you use the device itself and the generator for the electric shepherd correctly, it will do its job perfectly. However, when a stallion is overly active, even such an electric fence cannot stop him. For such individuals, it is better to duplicate the fence. Although the matter will be troublesome and cost "a pretty penny", but the horse will already be saved.

Separate nuances

Make sure that the tape does not touch the ground, grass or snow. Otherwise, the battery will constantly discharge to the ground.

The animal is trained to the device. After all, if a panic occurs during the first collision, then the horse can rush in a rush in the other direction and break the wire there.

In addition, to avoid unnecessary trouble, you need to hang signs for people warning about the presence of voltage.

Electric Shepherd Generator

The diagram below can be used to assemble the device. A base is used from a finished transformer, namely: from a machine. This is a device with low-resistance primary and high-resistance secondary windings.

Pulsations cause impulses. If in a car they act on candles, then in a processed form, the current is supplied to the electric fence.

For the operation of the device, a pulse voltage is sent to the primary winding (rhythmically repeating pulses of sound frequency). The process is implemented on three 555 timer chips, where infrasonic, sound vibrations and a single vibrator are collected.

The current for the electric shepherd is supplied to the primary winding by means of a key. Voltage is generated on the secondary winding, and audio-frequency pulses are output from the third timer to the gate of the transistor. Thus, a pulsating current occurs in the primary winding in the pulse generator for the electric shepherd.

The device is controlled by sound pulses at the fourth output of A3. Triggering occurs via the logical one level.

The infrasonic generator is assembled on the first timer. The frequency can be adjusted by the variable resistance R1.

From the third output of the first timer, the pulses go to the second output of the second timer, where a single vibrator is built. Each pulse arriving at the second output of the timer causes the generation of a corresponding pulse (the duration of which can be adjusted using the resistance R4).

The pulses of the third output are transferred to the fourth through the resistance R6. It turns out that the second timer sets the duration of high-voltage pulses that are transferred to the electric fence. In this case, the first timer sets their frequency.

Through the resistance, the pulse is sent to the gate of the transistor VT1. The primary winding of the transformer is connected to the drain circuit, and alternating voltage pulses are formed on the secondary winding.

Conclusion

Thus, assembling a generator for is the most difficult of the entire manufacture of the device. However, with basic knowledge, a radio amateur can do this without difficulty.

Electric fence use in his summer cottage contributes to an increase in the volume of grazing of domestic animals and the protection of the territory and site from the possibility of alien penetration.

The distributor of electric impulses used gives impulses of short duration and a voltage of about 700 watts. Since the resistance at the output of the distributor is high, when the pet touches the fence, the output voltage decreases from 600 W to 10 W, which is safe for pets. The distributor also contains a burglar alarm that is triggered after a short-term absence of pulses, a break in the electrical wire, or in the event of the distributor posts and cable tipping over to the ground and winding grass on the electrical wires of the electric fence. In addition, the alarm system performs night protection of pets.

The distributor of high-voltage electrical impulses is composed of two voltage converters, which are included in the electrical circuit one after the other. One of them is a relaxation generator on VT1 and VT2 radio receivers. After its rewinding, a series of short pulses is fed to the second thyristor converter, where the pulse frequency of the relaxation converter is controlled. The pulse frequency of the relaxation generator is tens of kHz, and the frequency of the pulses applied to the fence is several Hz, which makes it possible to achieve powerful and strong pulses from a weak generator.

Do-it-yourself electric shepherd: Scheme

Transformer TP1 is wound on armor rod B22, the number of windings is shown in parentheses. The fourth and fifth windings are made with PEV 0.31 wire, other PEV 0.18. Heat exchangers C1 and C2 - film dielectrics K 73 - 17.

Paper dielectrics C6 and C7. Instead of a high-voltage radio receiver TP2, an ignition coil was taken from a car. Structural elements outlined by a dotted line are installed on a printed circuit board, while others are mounted on a hinged installation.

Electroshepherd (electric fence)

An electric fence (electroshepherd) is a light wire fence, to which high voltage pulses are supplied from a special generator. The wire rests on insulators attached to metal, plastic, and wooden posts. The fence is designed to protect pens and pastures of domestic agricultural animals and poultry, crops from losses caused by livestock and animals, as well as to prevent livestock from entering highways and ravines.

The principle of operation of the electric fence is a short-term electric shock of high voltage when the animal comes into direct contact with the bare wire of the fence.

Installing an electric fence makes it much easier to look after animals while grazing. The electric charge that occurs when it comes into contact with the fence does not harm the animal at all, it simply scares it away, not allowing it to go beyond the boundaries of the allotted territory.

Thus, electric shock does not pose a danger to the life of animals and develops in them a stable reflex not to approach the fence with the installed system - the electric shepherd.

Electric shepherds for cattle (cattle), sheep, birds and other animals on the market can be powered by a network, battery or solar battery.

The price of the device depends both on the type of food and on the perimeter of the fenced pasture.

The range of choice of electric shepherds on the market is quite large.

Electric fences are produced both in our country and abroad. There is also a lot of information with an electric shepherd scheme on the Internet to make an electric fence with your own hands.

The main elements for building an electric shepherd (electric fence): a pulse generator, insulators, conductors, a set for a gate.

Electric shepherd for livestock video.

Video - the operation of the electric shepherd device for grazing sheep in action.

To protect your land from animals (and not only), you can use an electric fence, which is made of wire or metal mesh stretched on insulating poles, it does not come into contact with the ground, but is connected to a grounded source of high-voltage impulses. In relation to the life of animals or people, this does not pose a danger, but it gives a rather unpleasant and frightening sensation.

In order for the electric fence to perform only a frightening function, it is necessary to apply short high-voltage pulses to it, which are repeated at some interval.

The pulse generator can be made according to the scheme shown in Fig. 1. At the heart of the generator is a ready-made high-voltage transformer, its role can be played by an ignition coil taken from a passenger car. The ignition coil is a transformer with a low-resistance primary and a high-resistance secondary coil. When there is a ripple of current in the primary, high voltage pulses are formed on the secondary. In the car they go to the spark plugs, but here they go to the fence.

For the circuit to work, it is necessary to apply a pulsed voltage to the primary, which consists of interrupted bursts of audio-frequency pulses, they are repeated after a certain period of time. The circuit for recreating these pulses is made on three integrated timers of the 555 brand.

On the basis of timers A1 and AZ, generators of infrasonic and sound vibrations, respectively, were made. Based on the A2 timer - a single vibrator.

The current to the primary of the ignition coil T1 goes through the key on the field-effect transistor LG 1. In order for a high voltage to form in the secondary of T1, it is necessary that the current pulsate in the primary. Based on the AZ timer, a sound pulse generator was made. When it works, audio frequency pulses from its output (pin 3) go to the gate of the transistor. As a result, a pulsating current is formed on the primary T1, it induces a high alternating voltage on the secondary.

The sound pulse generator is controlled by the level at pin 4 AZ. In order for the generator to work on this output, a logic-one voltage is needed. At a logical zero, the generator is blocked and its output is set to a logical zero.

On the basis of the A1 timer, an infrasonic generator was made, it generates pulses. The frequency of these pulses can be adjusted using a variable resistor K1. The frequency of high-voltage pulses to your fence depends on this generator.

Pulses from pin 3 A1 go to pin 2 A2.

Printed circuit board

On the basis of the A2 timer, a single vibrator circuit is made.

Upon the arrival of each of the pulses at pin 2, it generates one pulse of a given duration, you can adjust it using a variable resistor K4. This pulse signal goes through resistor B10 to the gate of a powerful key field-effect transistor UT1A in its drain circuit, the primary of a standard automobile ignition coil T1 is connected. Almost any ignition coil can be used. It is better to use a coil from cars with a "contact" ignition system. For example, from the "Zhiguli" VAZ - 2101 or 2106, "Moskvich" 412 or 2140.

Today, correct and efficient grazing of animals can be carried out without the participation of people. To do this, there is a device called an electric shepherd.

With minimal human effort, livestock will be provided with food in the area limited by this design.

The number of grazing personnel is decreasing, as are labor costs. Such an organization of productivity is possible when using a special fence.

Controlling the movement of animals using this device will no longer be required. It is applicable for other purposes as well. It is quite possible to build a fence with your own hands.

What is an electric shepherd?

electric fence protects grazing animals from outside encroachment and limits their movement outside the structure, so that the surrounding area will also be safe.

The device is a generator that transmits current through the wire. Sufficient tension scares cattle away from the fence. At the same time, wild animals will not be able to attack a sheep or a cow.

What is the device for and how is it arranged?

For what purposes is the electric shepherd used:

• A mobile fence allows you to graze large, medium-sized animals and birds without the participation of people.
• Pets move freely within the site, and not on a leash.
• Electric wire protects against predators.
• The device is also applicable for fencing crops, dangerous areas on the landscape.

A home-made electric shepherd includes several elements, the main of which is a transformer. The layers of the core of its winding are separated by cardboard to increase the gap.

For winding, wire PEV 0.18 is used. The required values ​​​​of electrical capacitance are obtained using special capacitors designed for a voltage of a particular level.

Wire without insulation is fixed on insulators mounted on supports made of metal, plastic or wood.

The pulse source is powered by 220 volts.

The design consists of:

• grounding in the form of a pole or wire;
• a lightning rod that prevents the power supply from failing during a thunderstorm;
• conductors of the appropriate type, insulators;
• voltage generator.

Installation of the entire fence does not require the help of specialists. When buying a ready-made set, you need to separately purchase support posts.

What you need to create your own hands

The device is a simple design that you can do yourself. A do-it-yourself electric shepherd will cost much less than professional equipment.

The manufacture of such a corral, even for cattle (cattle), in the simplest case, requires a fence from only one line of wire.

Pillars made of metal or wood are taken as the basis, pointed at one end and carved at the other. Stretch electrical cables up to 200 m long.

Insulators are screwed onto the thread. The posts should have a length of a meter to 120 cm, they are located at a distance of approximately 10 m from one another.

If they are metal, installation is simplified. A crossbar is welded to the pointed end, which helps to install the structure.

The generator is purchased or made independently, for which the following elements are taken:

• a special coil, for example, from a car;
• battery;
• transformer;
• several transistors.

The electric shepherd circuit is implemented on a small plate hidden in a wooden box.

Important! You should not reduce the resistance of the converter by increasing the voltage to get a greater effect on the design. After all, the current passing through the cable will not be harmless to animals and people.

Scheme of the electric shepherd

The design, as well as the scheme of this device, are simple. The main part consists of a wire through which current is transmitted from a source - an ignition coil.

It is also a converter of voltage into pulses, which must be short so as not to cause harm when transmitted at a specific frequency. You will also need three 555 timers.

It is not difficult to make a generator. A ready-made transistor is used that performs the function of transmitting pulses. The ignition coil used in the electric shepherd circuit has two functions.

This is the generation of voltage and its transformation into impulses that are transmitted to the fence (unlike a car, where they go to candles).

The next (after creating the source) stage is the assembly of the structure, including the poles and the grid (wire). And after that the fence is connected to the generator.

Important! A scheme with short pulses should be chosen, since a long and powerful one can lead to the fact that the animal will not be able to leave the affected area. Unpredictability in behavior occurs due to muscle spasm. By that time, another electric shock will come, which can kill.

The selection of characteristics at the output of the current device is done for each variety of pets. Therefore, you should familiarize yourself with the publications of various authors on the Internet or other sources.

There are several schemes to choose from with wavelength options for animals of different sizes. But this characteristic can be adjusted on your own if you have more thorough radio amateur skills.

One of the schemes for cattle is shown below:

It's quite simplified.

Applied here:

• diodes (VD1, VD3) - KD226V and (VD4) - from 10 kV;
• resistance - 1 W;
• capacitors - 400 V;
• dinistor (VD2) - KN102I;
• thyristor (T1) - KU202N;
• coil.

Materials for the shepherd

When purchasing materials for a fence, they first of all focus on the distance between the supports - about 10 m. The wire must be with an anti-corrosion coating so that it can be used longer.

When purchasing materials for a fence, they first of all focus on the distance between the supports - about 10 m

When making a fence with your own hands, it is better to take a galvanized one, with a diameter within 2 mm. You will also need porcelain or ceramic insulators.

They are not afraid of moisture, natural phenomena. Although you can use ordinary plastic bottles, cut to the desired size.

Conditions for making an effective fence

For the functioning of the electric shepherd, there are a number of conditions:

• The fence installed around the perimeter is made of metal wire or mesh. The latter cannot touch the ground.
• Support poles must withstand high voltage.
• The source of high-voltage pulses must be grounded.

Important! An electric fence should scare away an animal, and not harm it.

Number and height of lines

The height of the supporting pillars is selected differently for each type of animal (optimally - 1 meter). The wire is stretched in the simplest case in 1 row, which is suitable for cattle. And also in two, three or more lines. The mesh that is most suitable for the bird is also applicable.

DIY installation

To install, you first need to determine the area of ​​\u200b\u200bthe site. Support pillars can be located at a distance of no more than 10 m from each other. The perimeter is divided by this interval.

It turns out the required number of columns. Each of them must be provided with an insulator to which the wire is attached. A simple option is a plastic bottle without a bottom, put on a pole. It is convenient to make coils of wire around the throat.

It is desirable to provide the wire with bright ribbons for greater visibility. People are warned by an inscription. Using a ready-made generator or making it from an ignition coil and three 555 timers, you need to ground the source.

To do this, one or more metal rods of 120 cm are taken, deepened into the ground by a meter. At the end of the installation, the structure is divided into sections, complemented by gates.

Advantages and disadvantages of a fence

Electric shepherd - a practical and convenient device

The principle of operation of the electric shepherd is as follows: the animal, in contact with the wire, feels an electric discharge of up to 3 mA and in the future is afraid to approach the fence at a close distance, to collide with it.

Such current power does not harm health, but only forces you to experience discomfort.

The generator of the installation is powered by the mains or a solar panel with a capacity of 12 volts or more. But the latter case is less efficient. The electric shepherd is a practical and convenient device.

Its main advantages:

• Ease of installation, mobility (can be moved to another location).
• Grazing is carried out without the participation of people, the corral works autonomously.
• Ease of construction.
• Small cost.
• Restriction of grazing of animals in a particular area.
• Can be used to protect plant crops from free-roaming livestock.

In the warm season, cattle spend up to 14-15 hours on open pastures. Pasture grazing has undoubted advantages:

• green grass is the best food for livestock;
• animals move calmly and unhurriedly, which favors the proper development of organisms;
• fresh air, sun - contribute to the growth of animals;
• grazing costs are much lower than camping costs.

Electroshepherd

It is unacceptable to enclose a summer pasture with a permanent capital fence for many reasons. Expensive, unresolved issues with land ownership, the impossibility of moving the fence if necessary ... And light temporary barriers will not help - the animals will either demolish them or simply not notice. Hire a shepherd? Again, costs, and it is not so easy to find a reliable employee.

In this case, an electric shepherd for cattle will become a reliable assistant. A simple device will allow you to create an inexpensive, lightweight, mobile fence.

Electroshepherd

Scheme and principle of operation

An electronic shepherd for cows and other livestock is a light fence, a chain of posts installed around the perimeter of a pasture, on which a conductive tape, metal mesh or just bare wire is stretched. With a frequency of approximately once per second, a short electrical pulse of high voltage is supplied to the conductive part from a special generator.

An animal that touches the fence receives a light electric shock, the strength of which is calculated so as not to cause any harm to the livestock. In this case, the impact produces an unpleasant, irritating effect, scaring away animals. After some time, a conditioned reflex is developed in the cattle and they begin to avoid approaching the fence.

The cost of an electric shepherd

How much does an electric shepherd for cows and other livestock cost? The cost of an electric shepherd depends on the following factors:

• Country of Origin;
• generator power;
• the perimeter of the fenced area (the number of supports and the length of the conductive fence);
• manufacturing material.

Important! On the one hand, the power of the generator affects the maximum perimeter of the fence, on the other hand, larger or longer-haired cattle will also require increased power.

For comparison, the cost of an electric shepherd from different manufacturers:

• production in Russia can be found for 13,500 rubles with a fence length of 400 m;
• production of the Republic of Belarus - 500 m for 5300 rubles;
• Finnish company Olli - 10,750 rubles per 1 km of the fence.

* - prices are indicated in Russian rubles, relevant for the fall of 2018.

For other characteristics, the device must be selected for each specific case.

Self-made electric fence

As you can see, there is nothing complicated in the device of an electronic shepherd for cows. If the farmer or his relatives know how to work with their hands and head, making an electric shepherd for cattle with their own hands should not present any significant problems.

Self-made electric fence

So, the three main components of the electric shepherd for cows:

• columns (supports);
• fence made of electrically conductive material;
• pulse generator.

Columns can be made from available materials at the rate of one column per 10 meters of a fence for small animals or 7-8 meters for large ones.

You can make supports made of metal, wood or plastic.

• Metal supports are strong, they are easy to drive into the ground when arranging a fence. But they require protection against corrosion, are relatively expensive, heavy, and insulators (purchased or home-made) must be installed on them.
• Wood poles are light, inexpensive, but harder to install. It is imperative to protect against decay, it is desirable to install insulators or measures to prevent impregnation with water (painting, impregnation with drying oil) - a tree swollen from water has poor insulating properties.
• Plastic posts are light, cheap, do not require additional insulators, you can use trimmings of plastic pipes left after the arrangement of the water supply, but it is even harder to drive them into the ground than wooden ones.

Important! Some types of plastics (polyethylene, some types of polypropylene) are not resistant to ultraviolet radiation (sunlight) and may break down after a short time in open space. Good in these conditions, fiberglass has proven itself.

The fence can be made from any bare wire, it will work in any case, but remember:

• steel wire is subject to corrosion, its service life in the open air is small;
• copper wire is expensive, tends to stretch over time under its own weight;
• the best option is galvanized steel wire: it does not stretch, does not rust, and is inexpensive.

Important! To increase visibility, the wire should be highlighted with bright colors - for example, flags or pieces of heat shrink tubing. This will help develop a conditioned reflex in animals. Signs with warnings for people from the outside of the fence will not interfere either.

Perhaps the most difficult section remained - the manufacture of a pulse generator. On the Internet at different addresses you can find a lot of schemes for such devices. We can recommend the following:
The advantages of such a scheme:

• simplicity;
• availability of components (three inexpensive 555 series timers, a few more parts);
• ease of setup;
• as the most responsible and time-consuming for self-manufacturing of a part - a high-voltage transformer - an industrial-made ignition coil from a carburetor car is used.

The power supply of the generator can be arranged through an adapter from a 220 V network, from a battery, from solar panels. As a ground, you can drive a metal pin into the ground (a piece of reinforcement, a pipe, a corner).

Pros and cons of using an electric shepherd

The disadvantages of using an electric shepherd include:

• poor sensitivity to electrical impulses of animals with thick wool (sheep);
• the need for a power source;
• it is required to periodically mow the grass along the fence;
• if the electrodes of the device are made in the form of a tape, repair in the event of a break is rather laborious.

Otherwise, farmers who have bought or made an electric fence for cattle give the device only positive characteristics: lightness, mobility, budget, autonomy.

A device such as an electric shepherd (a mobile electric fence on a pasture site) allows grazing various types of farm animals or birds without the direct participation of a person. Cattle grazing freely inside a fenced area do not suffer as much from blood-sucking insects as they do on a leash. The electric wire protects the livestock from the encroachment of predators. Electric fences are also used to protect sown areas or hay stocks from damage. It is possible to protect dangerous areas of the landscape (ditches, ravines) with a similar fence.

An industrial electric shepherd is quite expensive equipment. But if you want to save money, you can make it yourself at home.

Show all

The principle of operation of the device

An electric shepherd is a device that is a generator operating from a 220 volt network (or from a 10-12 volt battery) and transmitting current pulses to a bare wire stretched over the insulators of the support posts. The wire encloses the area inside which animals graze.

When touched, a current discharge passes through the body of the animal and goes into the soil to the grounding part of the device. A discharge of small force is not capable of harming the body, but causes discomfort in the animal. The reflex to bypass the wire is developed very quickly.

Do-it-yourself electric shepherd

Making an electric shepherd for animals (cattle, pigs, sheep, goats) with your own hands is a task that even a novice radio amateur can handle.

Most of the components necessary for this can be found on the farm. What you can't find, you'll have to buy.



Support posts

First you need to decide which area around the perimeter you want to fence. The maximum distance between two support posts should not exceed ten meters (if the animals are large and active, then even less).

To find out how many support posts you need, you should divide the perimeter of the site by the distance between them. A homemade electric shepherd can have support posts made from:

• metal;
• tree;
• polymer materials.

Metal posts (pins sharpened at one end) are heavy, but they are easy to drive into the ground. Carved from wood will be cheap, but fixing them in the ground will not be easy, you have to dig in. Ready-made posts made of polymeric materials purchased in a store are an expensive pleasure.

The height of the support posts is selected depending on the type of animals for which the electronic shepherd is made.



insulators

Each support post must have an insulator to which the wire will be attached. Insulators of industrial production sometimes appear on sale. Well, if they are ceramic.

You can make insulators with your own hands. A good insulator will come from a plastic bottle without a bottom. It is put on a post, and several turns of wire are made around the neck.

The wire

The wire must be resistant to adverse environmental factors. Iron will rust quickly. Well suited galvanized with a diameter of 2 mm.

By itself, a bare wire is hardly visible to animals, so it is worth using it in combination with brightly colored ribbons. There is also a warning label for people.

Generator and ground

You can buy a ready-made pulse generator for an electronic fence, but with some experience it is easy to assemble it yourself from an ignition coil and three 555 timers.

If an experienced radio amateur takes over, this scheme can be somewhat simplified or supplemented.

It is convenient to use an iron rod (one or several) with a length of at least 120 cm as grounding. The grounding is deepened by 1 m into the soil. In dry weather, for better electrical conductivity, the soil around the ground must be poured with plenty of water.
