Artificial Heart: It’s Development through Time

Our hearts are becoming fragile by the day. If we look at the statistics of USA, 610,000 people die due to heart disease every year. A large number of these deaths could have been prevented with the help of heart transplant but still there are too few hearts.

The first human heart transplant was performed by South African surgeon Christiaan Barnard. Soon surgeons around the world were transplanting hearts. But the problem was that all the recipients died within a year of transplant.

Since the late 1960s, doctors have been working on artificial heart. The most influential device was made by Willem Kolff, who invented the first dialysis machine for kidney.Kolff collaborated with fellow engineer, Robert Jarvik to work with him at University of Utah. What we got was Jarvik-7. It was made of two pumps, four valves and two air hoses. Due to its large size (like refrigerator), it could only be implanted in adults.

The US FDA approved the use of Jarvik-7 to be used on humans in 1982. Total five patients were implanted with Jarvik-7 but none of them survived more than 18 months. The device has been modified and renamed many times since then. SynCardia, a descendant of Jarvik-7 has been used many times.

Scientists are now working on a pulseless heart in which there is no heartbeat.

Effect of DDT Pesticides on Environment

There are a lot of environmental problems faced nowadays and most of those arise out of the human activities and the misuse of resources available to them. With the increase of the population on the Earth, the demand for food has also tremendously increased which has made the usage of pesticides essential for meeting the demands. However, it is adversely affecting the environment and proving to be a hazard for it.

The first usage of DDT was done in the form of chlorinated hydrocarbon. The full name of DDT is dichlorodiphenyltrichloroethane. The discovery of DDT was made by a Swiss chemist Paul Müeller in the year 1939. Initially, it was used extensively by people as it helped in killing a number of insects and pests without proving toxic to the mammals.

Due to its persistency, the effect of DDT remained for a longer duration when used once as it was not required to be applied often.  The main reason for this was its high tolerance due to which it didn’t get washed off by rain or got lessened by other weather conditions.

Gradually, due to immense usage of pesticides for growing more crops and getting rid of insects, the insects started growing resistant to the usage of DDT.  By the time, it was also revealed how DDT had disastrously polluted the whole environment with its dangerous chemicals. Though it is banned in a few nations, but still farmers have been using it in many countries for their profit.

Its continued usage has also proved cancerous for human consumption and has led to many other diseases in human beings. Animal lives are also affected as they eat the plants on which DDT is sprinkled.

The need of the day is to ban such harmful pesticides all over the world to save the environment.

Enjoy Whiskey In Zero Gravity

Imagine that you are a space tourist and you want to enjoy the finer things in life. For a start, let’s say you want to indulge in whiskey while enjoying your ride in space.

But, it would be impossible for you to pour the whiskey into the glass without gravity. The solution to this has been provided by Balantine, maker of Scotch whiskey. Their new product, the Space Glass has been designed in such a way that you will be able to enjoy the whiskey while taking delight in your space journey.

image001

The Space Glass, which was developed by Open Space Agency works on the principle of capillary action. This principle was first discovered by Leonardo DaVinci. A liquid has a unique ability to defy gravity while clinging to walls of narrow vessels. By following the same process, water travels from the roots of plants to the flowers.

The process of filling the Ballantine’s Space Glass is simple and unique. Whiskey is injected at the bottom of the cup through a valve. The valve is made up of 3-D printed plastic and goes into a reservoir. The whiskey then goes through narrow channel that spirals to a mouthpiece on the brim. What you need to do is suck in the beverage.

Japan’s Security Screenings for Passengers

Japan’s Security Screenings for Passengers

Security screenings is done in order to stop all skyjacking or any terrorism. Thus, it is very important that travellers are not allowed to bring weapons and other harmful items inside the airline.

Passengers who are on board should undergo security screening. This is done in order to make guarantee that all travellers can easily leave for their destinations and will be safe and secure on their flights.

In the article 86-2 of the Civil Aeronautics Act, it is advised that no one is allowed to bring any harmful and risky items inside the plane before the regulation of screening. These people include passengers, pilots, attendants, and everyone else who boards the airplane.

image005

Moreover, in order for airlines to involve in the aircraft business in Japan, they should acquire a “License” from the Minister of Land, Infrastructure, Transport and Tourism.

In order to get this permit from authority, every airline should provide to the Minister an “operation plan” (Civil Aeronautics Act Article 100-2).

It is evidently explained that this procedure should have include “Measures to Prevent Seizure of Aircraft and Other Acts” (Ordinance for the Enforcement of the Civil Aeronautics Act. These course of actions points out to security procedures that include the security screening for luggage. This is the reason why security screening for travellers in Japan airports is supervised by every airline.

Narita International Airport act jointly with every airline in imposing flight security procedures to ensure the safety and security of passengers and airplane.

Your Journey To China

Tips For Your Journey To China

There are many differences between China and America, especially cultural. Culture shock is a phenomenon arising from cross-culture communication; it happens when different cultures clash with each other. Because the people live in different countries, they have different education, different languages and different cultures from birth. In order to avoid culture conflict, there are three important cultural habits which a visitor to China should be aware. The three cultural habits are about eating, demanding reciprocity and tipping.

A visitor should know how to eat the correct way in China. It’s the first difference that we use different tableware for eating. In America, people use knives and forks as the main tableware for eating, but in China, people use chopsticks for eating. In China, most restaurants don’t provide knives and forks. They only have chopsticks. It is important for foreigners to learn how to use chopsticks before they come to China. The second difference when it comes to eating is sharing food. In China, when we go to restaurants, we order food together and share it together with our companions or families. After we order meals, the waiter will put all the dishes on the table; everybody sits around table while eating; everybody is eating the dish on the same plate with his own chopsticks. In America, people order their own meals and eat their own food. So when you are in China, you should share food of the table with people while eating. The third difference is that when you are invited by your Chinese friends to go home for dinner, the host will put the dish into your bowl. If you encounter this situation; don’t worry. They just want to show that they are very friendly and they really like you.

A visitor should also know that courtesy demands reciprocity which means to return politeness for politeness: proper behavior is based on reciprocity. For most Americans, if somebody pays their bill; they will be really happy and appreciative, they don’t need pay back. But in China, if somebody pay your bill, you should remember to pay him back. Although they offer to pay your bill, you have to pay back to let them know that you are polite, you are not a stingy person, and you want to keep contact with them. As you do this way, they will want to keep good friendship with you. As the same thing, when you are in China, your friends from there might give you gifts; you need give back to show your politeness. They do these nice things for you to show their politeness, so you, as the recipient, should return your politeness and amity back to keep the harmonious friendship. Demanding reciprocity is a traditional custom in China, when you know this costume, you can avoid some unnecessary misunderstandings during your journey.

The third difference a visitor should know is that Chinese people do not give tips. In America, a customer give tips to all kinds of servers as a way of thanking for their service; it as a traditional custom in American culture. The reason is that workers with service-industry jobs can only get a small salary from their boss; they rely mainly on guest’s tips to make money. But in China we have different processing way; we don’t give tips to others. In China, workers with service-industry jobs, their boss pays them a handsome salary as a reward for their work. These years with the more communications between China and America. Some big cities in China, have begun to pay tips, especially some upscale restaurants and hotels. Now many Chinese changed their mind, they also thought that we should pay the tips, and paying tips is should get normal. But in small cities, people still keep their traditions without paying tips. Personally, I think the difference in tipping does not mean one side is wrong or right. It is because their cultures are different and now with the communication between the world, this kind of situation may be solved in the future.

There are three habits that a visitor should know when going to China. They are about eating, demanding reciprocity and tipping. These tips will help you for your journey of China. Have a good time in China!

Background on Southeast Asian Parenting

Background on Southeast Asian Parenting

In order to understand the parenting styles of South Asian parents, we need first to understand the learned and shared experiences within social groups that shape the parents’ personal connection on their family.

Normally, Southeast Asians consist of many family members that come from three or four generations living together. Usually, nuclear families consist of four to eight children, depending on the economic stability and social status and cultural group.

image002

The culture of Southeast Asian centers on the person’s religious, economic, political and social part in the family. It also gives an understanding that the responsibilities of every member of the family are for the benefit of each other. As a concrete, example, older parents and siblings must nurture the children as they grow so that when the time comes that they are mature enough to handle responsibilities, they will take the responsibility to take care of their aging parents or siblings. Family relationships and responsibilities are clearly explained. Helping each other is a two-way process that makes their relationship stronger and creating successful tasks will help each other grow.

When it comes to raising their children, Southeast Asian parents give importance to education and knowledge because knowledge is essential for wisdom and goodness. Older parents and scholars are greatly honored because of their learned experiences and deep understanding. Parents from Southeast Asian countries want their children to receive good quality education, even though this has traditionally been very true for their children. Every time a child finish his or her degree program pursue his or her wildest dreams, he or she is honored by the whole members of the family an gives the person. The wisdom from elder members of the family is connected from the ancestral practices and importance of tradition.
