Exploring the wild? Don't take the tent wrong

Tents are important equipment in the wild. Some tents are now increasingly innovative, not even needing to stand on the ground, but hang on trees. Tents are widely used by soldiers in history and over time are used for recreational purposes by civilians.

Tents are home to outdoor explorers, a place to rest after traveling up a mountain, exploring the forest and along the river. Tents are also a place to protect yourself in extreme weather.

Tents generally have two coating principles for protection. The inner wall is made of breathable material or non-waterproof material and an outer wall or flysheet made of waterproof material. Both have different goals and functions.

A breathable material aimed at overcoming condensation generated by the user and some activities in the tent. Condensation occurs by the heat generated by the body or cooking activities in the tent. The inner wall made of non-waterproof material will allow the heat to come out.

Waterproof material for the outer wall is made to prevent rainwater and wind from entering the tent. This layer has a very tight structure and will not have pores or air holes. Some types of tents have both layers, but other types only have one layer and flysheet as an additional support.

Bivouac tent

Bivouacs are temporary or emergency shelter tents that are useful for shelter in bad weather. Bivouacs are usually made using a poncho raincoat.

Platoon tent

These tents have a long history and are most widely used for military missions and temporary shelters in a natural disaster. To set up this tent requires several people and this type of tent is made of materials that are very strong and accommodate many people.

Dome tent

Dome is the most popular tent. Although low capacity and not as strong as platoon tents, this type of dome tent has many advantages including compact and accommodated into backpacks. The simplest dome only weighs 2 kg and 4 kg for larger sizes.

Tree tent

This tent is a special type that is hung on a tree. A special sensation where sleeping users hang from trees. This type is very good for explorers to carry in watery environments.

Dry Valleys on Antarctic continent is the driest place in the world

The Sahara Desert is the largest desert in the world, rainfall is very low, only stretches of sand and rocks without rivers and plants further strengthen the view of drought. However, it turns out that the place is not the driest place in the world. Dry Valleys in Antarctica, although the continent is covered in ice, but has one part that is completely dry. Although the average rainfall in most of the Sahara Desert is less than 20 millimeters per year, there are still drier places. Dry Valleys in Antarctica is much drier where the average rainfall is 0 millimeters per year and gets the title of the driest place in the world. The valleys have so low humidity that there is almost no ice. This is the largest ice free place on the Antarctic continent. The area is surrounded by mountains that block ice from flowing into the valley. Drought is also caused by strong katabalic gusts from mountain peaks where cold air blows down the hill due to gravity. The wind has speeds of up to 322 k...

Humpback whales (Megaptera novaeangliae) manufacture bubble-nets as tools to increase prey intake

NEWS - Humpback whales ( Megaptera novaeangliae ) create bubble net tools while foraging, consisting of internal tangential rings, and actively control the number of rings, their size, depth and horizontal spacing between the surrounding bubbles. These structural elements of the net increase prey intake sevenfold. Researchers have known that humpback whales create “bubble nets” for hunting, but the new report shows that the animals also manipulate them in a variety of ways to maximize catches. The behavior places humpbacks among the rare animals that make and use their own tools. “Many animals use tools to help them find food, but very few actually make or modify these tools themselves,” said Lars Bejder, director of the Marine Mammal Research Program (MMRP), University of Hawaii at Manoa. “Humpback whales in southeast Alaska create elaborate bubble nets to catch krill. They skillfully blow bubbles in patterns that form a web with internal rings. They actively control details such ...

Tripa tiger moth (Nannoarctia tripartita)

Tripa tiger moth ( Nannoarctia tripartita ) is an animal species in the Erebidae, a moth with a forewing length of 14-18 mm, predominantly black or dark brown with white and orange hues, thick fur on the dorsal surface, long legs and antennae, living in forest scrub and agricultural land.

Males have forewings 14-17 mm long, black or dark brown with transverse oblique postdiscal bands and several spots.
