How do ants fight gratification and crawling on walls?

We are a company engaged in the sale of medical devices. Instantly, thousands of ants freely got out of the ground and climbed onto the walls of the bucket. Luckily I held onto the bucket lid. How do ants so easily crawl on walls, ceilings and other surfaces? I have been studying ants for 30 years, and their abilities have always amazed me. In addition, you can also use the tools that are at the bottom, such as at the bottom. Human hands versus Ant feet to understand Ant feet, we must compare them to human hands. Your hand has one broad part, which is the palm with four fingers and the thumb in need. Each finger has three parts, while the thumb has only two. Hard nails grow from the tips of your fingers and thumbs. Human hands versus Ant feet to understand Ant feet, we must compare them to human hands.

Your hand has one broad part, which is the palm with four fingers and the thumb in need. Each finger has three parts, while the thumb has only two. Hard nails grow from the tips of your fingers and thumbs. Humans have two hands-ants have six legs. Ant legs are similar to human hands, but more complex, with the addition of some strange-looking parts to enhance them. Ant legs have five jointed sections, with the end section having a piece of cake. Its claws are shaped like cat's claws and can catch on uneven surfaces on walls. In addition, you can also choose a material that suits your needs, such as bark. In addition, you can also choose the type of shoe that suits your needs, just like the human foot is protected by shoes. However, the feature that really forms the human hand from the Ant's foot is the complete relief that it can develop, called arolia. Sticky feet Long legs are visible between the claws at the end of each leg of the Ant. This balloon-like Relief allows ants to defy gravity and float on ceilings or very hard surfaces such as glass. When an ant walks on a wall or ceiling, gravity causes its paws to swing wide and pull back. At the same time, the muscles of the Ant's legs pump fluid into the pillows at the ends of its legs, causing them to expand. This body fluid is called hemolymph, which is a complete liquid similar to human blood that secretes blood all over the Ant's body. In addition, we also provide a wide range of products at affordable prices. However, when an ant raises its legs, the muscles of its legs contrast and suck most of the liquid back into the pillow and then back into the legs. In this way, the blood of ants is used repeatedly – merged from the legs to the pillow, then stopped back to the legs – so that nothing is left behind. 

In addition, there are several ways that can be done to solve the problem. In addition, when they are underground, which is their home, ants use complete help to sleep on the ceiling. By sleeping on the ceiling, ants avoid other ants moving on the floor of their house. Unique gait as you walk and move forward, your left and right feet move in sequence, with one foot observing the ground while the other foot is in the air. With three on the surface and three in the air at once. 

The walking pattern of the largest ants is unique when compared to other six-legged insects. In spring, the front and back left feet are on the ground with the middle right foot, while the front and back right foot and the middle left foot are in the air. Then they changed. You can try to imitate this three-part pattern by using three fingers on each hand. If after this you see ants crawling on the wall, look carefully and you will probably activate between pulling this thing. Deby Cassill professor of Integrative Biology, University of South Florida

This Ant treats its wounded meal

African Matabele ants (Megaponera analis) have to risk their lives and potentially even be injured while hunting termites for their food. However, there are interesting and unique things observed from the way these ants treat their injured friends. A study revealed, when they are injured, there will be other ants who help take care of them. 

Quoted from Phys, Thursday (29/9/2022) Erik Frank, a researcher from Julius Maximilians University in Wurzburg who has studied insects noticed that ants lick other ants that are injured, for example a cut leg. This behavior is intended to prevent infection, and the treating ants are likely to use antimicrobial substances. 

"In the substances used we found more than a hundred chemical components and 41 proteins. Of about half we have already been able to prove that the substances have antimicrobial qualities," says Frank. The substances, according to him, are very efficient, about 90 percent of the ants treated were found cured. In his three-year study, Frank found ants produce a substance in sac-like glands behind their chests, called metapleural glands.

The ant that acts as a helper or who will treat his injured friend, will then take these substances with his feet and then put in a new mouth after applying the wound to the injured ant. Until now, it was assumed that only humans were able to diagnose the infection and subsequently treat the wound with antimicrobial substances. However, it turns out that studies on ants reveal the unexpected and so far a unique thing in the animal kingdom. Frank also observed Eciton ants found in Central and South America. Wound healing by other ants has also been found in these ants.

The difference is that Eciton ants do not immediately bring them back to the nest but take care of them on site. Furthermore, Frank already plans to carry out studies on other insects such as bees or termites. 

"Insects are well suited for observation and experimentation. But this kind of behavior can in principle be studied in all species of social animals, for example chimpanzee mothers who catch insects, chew, and apply saliva to the wounds of their children," Frank explained. In addition, the study of antimicrobial substances produced and used by these ants to treat injured friends, maybe in the future can also be used for human treatment.

Know the Anemometer, a device for measuring wind speed

Anemometer is a device for measuring wind speed and wind pressure.  Anemometer is an important tool for meteorologists who study weather patterns.  The most common type of anemometer has three or four cups attached to a horizontal arm attached to a vertical bar.  

When the wind blows, the Cup will rotate and make the rod rotate. The stronger the wind blows, the faster the spinning rod eats. According to National Geographic, anemometers are used in almost all weather stations. Wind speed helps indicate changes in weather patterns.

This type of anemometer is used in speed experiments.  Typically, laser anemometers are used to calculate wind speeds around cars, airplanes, and spacecraft, for example. The process of wind is reported from the learning resources of the Ministry of Education and culture (Kemdikbud), wind occurs due to differences in air pressure or differences in air temperature in an area. 

This condition is related to the amount of solar thermal energy received by the Earth's surface.  In a region, areas that receive greater solar thermal energy have hotter air temperatures with lower air pressures.  Therefore, there is a difference in temperature and air pressure between areas that receive greater heat energy with other areas that receive less heat energy so that air flow is formed in the region.

Types of wind and its definition and formation process

Wind is air that moves from high pressure to low pressure or from low air temperature to high air temperature. 

The wind does not have much substance, it cannot be seen or held, but its force is strong enough to carry ships sailing across the ocean. In general, winds are divided into two groups, namely local winds and seasonal winds. 

Reporting from the Ministry of Education and culture, the following are the types of local winds and seasonal winds. Local winds local winds are divided into three, namely land winds and sea winds, mountain winds and valley winds, and tornadoes or whirlwinds. Also read: Where does the wind come from? Land winds and sea winds land winds and sea winds are formed due to differences in the nature between land and ocean in absorbing and releasing solar thermal energy.  

In this case, the land absorbs and releases thermal energy faster than the ocean. Land winds are formed at night, when the heat energy absorbed by the Earth's surface throughout the day is released more quickly by the land (cold air). Meanwhile, thermal energy in the oceans is in the process of being released into the air. The convective movement causes cold air from the land to move to replace the air rising in the ocean so that there is a flow of air from land to sea. Typically, land winds occur at midnight and early in the morning.

5G Network Officially Operates, Digital Transformation Accelerates

entering a new round of Information Technology. Since Monday (24/5/2021), 5G cellular networks have begun to operate commercially worldwide. The first operating 5G mobile network is based on IMT-2020 (International Mobile Telecommunications-2020) technology in the 2,300 MHz or 2.3 GHz frequency band.

When inaugurating this network service, minister of Communications and Information Technology (Kominfo) Johnny Gerard Plate stated that the operation of the 5G cellular network is the fruit of the work of the government and telecommunications providers as well as a manifestation of the acceleration of digital transformation in the world

Before it was launched, the Ministry of communication and information together with several telecommunications providers had conducted 12 5G network trials throughout 2017 to 2020.

"One of the trials was carried out during the Asian Games in 2018. In early 2021, the Ministry of communication and information has also conducted an auction for the 2.3 GHz frequency band," explained Minister Johnny.

This 5G network service also marks the stage of simultaneous operation of 4G and 5G in the country. Thus, the presence of 5G services does not necessarily displace 4G services that are already used by the community. Because, in the early development stages, 4G networks are also needed as a base for 5G operationalization.

As a new technology, 5G network will certainly encourage the advancement of world digital sector. To be sure, 5G services are faster and have greater network capacity while being reliable compared to 4G networks. In addition, 5G technology will unlock the potential of services not only for human-to-human communication, but also integrate human-to-machine networks and machine-to-machine communication networks.

In order for 5G services to be more optimal,  needs frequency spectrum allocation at least in three layers, namely low band, middle band, and high band. 5G is a very flexible technology. This means that the technology can be applied to both Mobile Broadband and Fixed Broadband or Fixed Wireless Access (FWA) services.

The frequency bands in the low band and middle band layers, such as the 700 MHz, 2.6 GHz, and 3.5 GHz bands, are more suitable for use as 5G Mobile Broadband services. Currently, 5G mobile Broadband will be prioritized in the development of 5G in World.

The Ministry of communication and Information also seeks 5G Fixed Broadband services in accordance with world standardization, namely by utilizing spectrum bands in the high band layer, such as the 28 GHz frequency band which has a large transmission capacity.

The Ministry of communication and information has issued a Certificate of operational eligibility (SKLO) 5G services to PT Telkomsel as its first provider. The issuance of SKLO is based on the implementation of the operational feasibility test (ULO) on 19 to 20 May 2021. Based on the ULO results, PT Telkomsel was declared operational worthy after the Ministry of communication and Information conducted technical testing of PT Telkomsel's facilities and infrastructure in operating the 5G network.

Digital Transformation

5G technology is believed to be able to accelerate socio-economic and cultural transformation digitally. One of the advantages of 5G networks is high data transfer rates and low latency.

The implementation of 5G network is predicted to be able to deliver fast, smooth, and even instant streaming and downloading experience.

This condition is reflected in the Covid-19 pandemic last year, where internet network usage jumped rapidly to 300 percent. The results of the Global Web Index 2020 survey further emphasize the demands of video content consumption from consumers. As many as 51% of Gen Z prefer online video content for their media consumption, while 31% choose online TV.

Meanwhile, 64% of customers are more likely to buy a product online after watching a video about it. This is the main reason why e-commerce giants such as Shopee, Tokopedia, and Lazada prefer to promote their products through online video marketing.

Meanwhile, Global Information and communication technology provider Huawei sees the use of 5G networks has experienced rapid development, especially when many industries began to adopt the technology.

By 2020, at least 140 commercial 5G networks had been deployed in 59 countries and more than 50 percent of those networks were built by Huawei. The use of 5G applications as part of the core production process in the industry has begun to bloom in 2021. 5G applications have been deployed in more than 20 industries, including manufacturing, healthcare, education, and logistics. One is used as a logistics loading and unloading automation system in one of the busiest cities in the world, Yanshen Port, Shanghai. 5G technology can significantly reduce logistics costs in ports.

The government together with digital industry players have begun to prepare devices and ecosystems when the 5G network begins to be applied in Smart city, manufacturing, e-commerce, health, and logistics industries.
