Be careful, Hearing Loss at a Young Age Can Happen ..!

Hearing loss at a young age can affect teenagers who are not concerned about the environment. In addition to rare, teens rarely complain about hearing so that hearing loss at a young age rarely arise.

Why are parents ignorant of the threat of hearing loss problems in their children? Hearing lost in children or adolescents often occurs unnoticed by parents. This is because in general, hearing loss occurs due to Presbycusis factor.

Presbycusis occurs in the elderly. Presbycusis is a hearing loss of neural sensors in the elderly due to the process of degeneration of the hearing organ that occurs slowly. Hearing loss due to presbicusis factor occurs symmetrically on both sides of the ear and can not be cured. Hearing Aids can help people with age-related hearing loss Presbycusis this type. Free-technews.info will display the article in the future. Parents need to pay particular attention to preventing hearing loss in children and adolescents.

Hearing Loss at Young Ages Due to Exceeding Limit Sound.

Hearing loss in children or adolescents can occur due to sounds that exceed the hearing limit. The sounds we hear are vibrations of sound source objects that vibrate the air around them and through the air medium, the sound travels to our eardrums. Sound is the movement of waves in the air. The sound source converts the nearest particle from a stationary position to a moving particle. The energy contained in sound can increase rapidly and can travel a great distance.

Hearing lost in young age, children or adolescents can occur due to sounds that are too long received ear, in addition to exceeding the hearing limit. Most parents do not care about seeing her children and her peers who always wear earphones in plenty of time. Earphones or headphones become a faithful companion for teenagers as well as adults. Many equipment that utilizes voice features to maximize the satisfaction of consumers, such as television, car audio, home theater, computer games, mobile phones and others. Some additional equipment such as sirens, exhausts have an extra loud sound.

Actually there is another side of technological developments that cause negative effects, one of which the effect on hearing loss. Many of these devices have poor quality. Poor audio equipment quality can also be one of the contributory factors of hearing loss

Hearing Loss at Young Ages – Noise Induce Hearing Lost (NIHL).

The most common hearing loss due to the effects of technological development is Noise Induce Hearing Lost (NIHL). People are too engrossed to play new games on the computer for example, often forget the noise is too noisy. Who is the most enthusiastic about technological development? Yeah, right, young generation. Children and adolescents suffer from hearing loss if the use of modern equipment is not suitable for their capacity or exceeds a safe range in use.

A simple method to prevent your children from hearing loss Noise Induce Hearing Lost (NIHL) is paying attention to the use of modern equipment. You must limit the time of use of the equipment and the intensity of the sound (volume). Choose audio equipment that has good quality.

Agricultural Land Changes to Critical Land

Agricultural land can change to critical land. Knowledge of change to critical land is used to support the cultivation of plants in our garden.

We will encounter greater obstacles when meeting this critical land than fertile land. How is agricultural land change to critical land? How did the critical land occur? In essence, the change to critical land occurs due to the continuous decline in land productivity. The decrease in soil productivity is caused by decreased soil fertility.

Causes of Agricultural Land Changes to Critical Land

There are several factors that cause the conversion of agricultural land into a critical land. The factors causing the change to become the critical land are among others :

Farmers continue to cultivate agricultural land without proper crop management, soil and water.

In some countries, critical land occurs due to shifting cultivation systems accompanied by logging and burning of land.

The practices of agricultural systems that do not take into account the concepts and efforts of soil conservation.

Critical land can occur due to natural disasters, such as field or forest fires, and floods.

The critical land is essentially land where the physical, chemical, and biological conditions of the soil are not productive in terms of agriculture. The critical land is mostly caused by physical damage to the soil. The physical damage to the soil is mainly due to the loss of topsoil which is fertile due to erosion. Such land leads to unproductive farming.

Another impact of erosion hazard is the destruction of the hydrological functions of agricultural land, the silting of rivers, reservoirs, dams, waterways, and environmental pollution.

Critical land faces two main issues.

Critical land facing problems encompasses two points of interest.

How to repair/rehabilitate degraded land becomes productive land.

How to prevent the rehabilitated lands from the physical damage of the land based on the geographical location of the land.

We need to consider in terms of cost and technicality to rehabilitate or prevent the emergence of critical land. Difficulties that are too great in dealing with critical land will burden our farming cultivation.

River Conch As an Alternative Source of Protein.

We need an alternative source of protein for various reasons. Some of us need an alternative source of protein on the grounds of dietary variations. While in developing countries, they need alternative sources of protein due to limited budget and availability of natural resources.

A small number of people in some countries consume river conch. They cook in different ways, roasted, fried, boiled or cooked like cooking seashells. For the community, shellfish or rice field shell is one alternative source of protein that can be obtained by easy and easy from nature.

Some people may feel disgusted to eat the meat of this river conch because a little slimy. The unattractive shape also makes people lazy to consume river conch.

Is it true that this river conch is an alternative source of protein?

The protein content of river conchs reaches 12% per 100 gram. When compared to beef only slight difference because beef contains protein that reaches 18% per 100 grams. So, this snail meat deserves in use as one of an alternative source of protein. When viewed the cost to get it, the river snails hardly cost anything. This snail is derived from the wild and no one has cultivated it.

The conch meat has a sweet taste like a shell with a chewy and fibrous texture. That’s why river shells can be cooked with a variety of recipes and have fans.

In addition to protein, the nutritional content of snails includes calcium 217 mg, calories 90 calories, fat 1 gram, sodium 70 mg, Carbohydrates 2 grams, vitamin A 2%, niacin and water 81 grams.

The river conch should be cooked in a good way for maximum taste and eliminate the smell of mud. You should soak and wash it over and over with a clean so that the smell of mud and mucus is lost.

This chewy snails need cooking time equivalent to cooking beef or chicken. You can boil, fry, roast or combine cooking methods to grow the maximum taste. You can use marine shellfish recipes.

In some areas of the country, these river shells are believed to have herbal properties. High calcium content makes this snail used for healing bone problems. And in some places also believed to cure hemorrhoids.

Review of Earthquake Resistant Building Structure

The review of earthquake resistant building structures is very useful for residents who live in earthquake areas. They need technical access to earthquake resistant building structures. So they can adjust the resources available around them with earthquake resistant building structures.

In order to become a building that is resistant to earthquake then you need to pay attention to the structure of the building.As in the review, this structure will discuss Footings, columns/ post, roofs, and walls.

Earthquake resistant building structures – Footing.

The Footing is a lower structure that holds the structure above and forwards the load to the ground so that the Footing satisfies the following.

You must choose a solid ground to place the Foundation, which is laying the foundation on a hard ground. Footing lies deeper than 45 cm below ground level. The whole Footing must lie on a strong ground.

You must connect the Footing with the footing belt (sloof). This gives on the local footing (pedestal) and the continuous footing.

Sloof / the footing beam (sloof) should be lumped on the Footing with a 1.5 m with 12 mm diameter iron reinforcement.

You should not lay the Footing too close to the cliff wall to avoid landslides.

To prevent cliff slopes, you should provide a ground holder with a rock-stone pair or from a bamboo or wooden plaster.

Earthquake resistant building structures – Column / Column.

columns or poles to help the wall in holding the load above it while making the wall into a ductile wall. The things to note in the column are as follows.

Buildings should use columns as load-bearing elements, eg using reinforced concrete columns.

The column should be laid on the Footing beam (sloof) or the bond is passed to the Footing.

You must tie at the top end of the bony column or each column. You need to put it together with a beam around / ring balk.

Building frames (Sloof, beams, and columns) should have a strong and sturdy relationship.

The column should be equipped with a stiffening beam (ring balk, latei beam) to withstand the lateral force of the earthquake.

Earthquake resistant building structures – Building Beams.

The beams on simple house building consist of ring balk (beam around) and lintel beam. Latex beam/lintel has a function as a horizontal reinforcement and is generally located above the frame. Crosslinks can be mounted when possible.
