There was a mummy in the National Sculpture Museum in Munich, Germany. Today, there are more than 1000 such mummies in the world, but only 100 remain on the corresponding mummies. The mummies of the other 900 portraits are unknown. The reason why archaeologists chose to restore the child's mummy is that it is the "old man" in the museum. Judging from the restored mummy, the ancient Egyptians do have black characteristics, but the aesthetic has been Europeanized. After all, they were ruled by the Greeks and Romans for so long that they still thought the master looked good. So even the portraits after death were imitated by European people.
From the perspective of hemorrhoids, another 10 hemorrhoids are obviously exaggerated by people. Hemorrhoids is not a serious disease, but it makes people "uneasy" and seriously affects our life. Hemorrhoids most can think of is stool with blood. In fact, this is only a manifestation of internal hemorrhoids, external hemorrhoids, mixed hemorrhoids, in which external hemorrhoids are mainly manifested as anal discomfort, unclean moisture, itching, etc. Improving anal movement can promote the blood circulation of anal part and increase the strength of sphincter.
Prevention of arteriosclerosis is the primary prevention of arteriosclerosis. It is mainly aimed at the risk factors of arteriosclerosis for preventive treatment. The main risk factors are: 2. Dyslipidemia is the most important risk factor of arteriosclerosis. Clinical application of statins can well control blood lipid and delay arteriosclerosis. 4. Smoking and passive smoking, smoking can increase the incidence of this disease by 2-6 times. In recent years, it is advocated to prohibit smoking in public places. 5. It is suggested that the fasting blood glucose should be controlled at 7 mmol / L.
Texas Environmental Quality Commission issued an emergency notice saying that "brain eating insects" might be found in the water supply system of a county in the southeast of the state, and issued a warning to more than ten areas of the state, advising people to "do not use water"! The Texas Environmental Quality Commission issued a warning on social media on the same day that the water supply system of brazosport Water Bureau may have "Neri flexneri". "It is not clear how long the measures will take." Its water quality can also be recommended by the State Council for drinking water, but not for flushing water within the range of the toilet.
It can be said that the role played by the earth's living things in the ecosystem can not be replaced by human beings. For Australia, it can be said that whale stranding has occurred in the past, but this one may be a more serious grounding event in Australia's history, and it is one of the largest strandings in the world. The area where the whale stranding occurred is located in the west coast of Tasmania, Australia. According to whale behavior experts, this may be related to the habits of whales. When some whales run aground, this highly social creature will try to reunite with their "family members" and "friends", thus causing more whales to land.
One of the advantages of tea drinking in the United States is that they have just learned to drink tea and have a bad effect on atrial fibrillation. Because I treat atrial fibrillation, premature beat and other arrhythmias every day. I have seen a large number of patients. They are induced by drinking coffee, and drinking coffee can aggravate it. So, in this sense, I feel flustered when I drink coffee. It may not be enough to say that it is heart disease, but it shows that the heart is not so strong.
This year's Mid Autumn Festival is coming, and it's time to enjoy the moon. According to astronomical experts, this year's mid autumn moon has 16 circles on the fifteenth day of the lunar month, and the roundest moment occurs at 5:05 a.m. on October 2 (August 16 of the lunar calendar). Shi Zhicheng, member of the Chinese Astronomical Society and director of the Tianjin astronomical society, said that on the first day of the lunar new year, we can not see the moon, which is called "new moon", also known as "new moon"; around the 15th day of the lunar calendar, we can see a round moon, called "full moon", also known as "Wang". According to the lunar calendar, "Shuo" is located on this day
Recently, the research team of Professor Zhu Huanzhang from the State Key Laboratory of genetic engineering of Fudan University published a research paper entitled "PEBP1 suppress HIV transcription and induce latency by inactivating MAPK / NF - κ B signaling" online in the international famous academic journal emboreports. The researchers also found that when pepp1 was induced by EGCG, it inhibited nuclear translocation NF - κ B, which in turn inhibited the reactivation of latent HIV viruses isolated from the primary CD4 + T cells of HIV positive patients receiving antiretroviral therapy.
Where to learn greenhouse planting technology? Some novices want to do greenhouse planting, there is such trouble: they have land, but they have no greenhouse planting technology and experience, so where to learn reliable and professional greenhouse planting technology? In addition, what you need to pay attention to is that the local government still supports the greenhouse vegetable planting. You'd better make use of the government's resources to consult about the details of greenhouse planting technology, subsidies, etc., so that you can analyze your own situation and see whether it is suitable for greenhouse vegetable planting projects.
Since the folk potted fruits and vegetables were planted indoors, this trend has spread rapidly in the circle. For a long time, Xiaohua was worried about what kind of plants to cultivate. As the name suggests, the branches of multicolored peppers are hung with round heads of different colors and colors. They look tender and lovely. Now let's take a look at how to take care of the colorful pepper on the balcony! Xiaohua thinks that, compared with ordinary pepper, colorful pepper is really a kind of potted vegetable with high appearance value. It is no wonder that people prefer to cultivate it as ornamental plants in life.
A fire broke out in Huawei's Dongguan laboratory. The following laboratory technology academy will inventory the common safety knowledge of the laboratory for you. Too many laboratory safety accidents are caused by improper operation. Safety training and education are the top priority to eliminate laboratory safety accidents. Special attention should be paid to standardizing the laboratory safety warning devices and fire-fighting equipment, standardizing the construction of water, electricity, gas, ventilation and other systems in the laboratory, standardizing the classification and storage of various reagents or flammable and explosive materials, and the discharge and treatment of various wastes or poisons, so as to eliminate the potential safety hazards in the laboratory in the bud.
Background? We are all familiar with graphene. What about graphene nanobelts (GNRs)? By definition, graphene nanobelts are graphene ribbons with a width of less than 50 nm. Its theoretical model was first proposed in 1996. In order to give the single-layer graphene some electrical properties, graphene nanoribbons are formed by cutting graphene according to specific patterns. The shape of the cut edge can be divided into zigzag shape and armchair shape. The calculation using the tight binding approximation model predicts that the zigzag shape has the metal bond property, and the armchair shape has the metal bond property or semiconductor
On the night of September 25, the astronomical landscape of double stars accompanying the moon can be seen in the night sky of the South sky. The double stars are Saturn and Jupiter. The next few nights, September 23, 24, 25 and 26, 2020, will feature the moon and Jupiter and Saturn, the two largest gas giants in the solar system. The planets that orbit the sun outside the earth's orbit are Mars, Jupiter, Saturn, Uranus and Neptune. So in the next few days, the moon will pass by Jupiter and Saturn. Most importantly, we can also observe lunar landforms, Jupiter's moons and Saturn's rings where there is a bright moonlight or is affected by light pollution.

Since then, Lin Lanying led the team to set many firsts for China and made great contributions to China.
According to the prediction of the food and Agriculture Organization of the United Nations, the total population of the world is expected to reach 8.5 billion in 2030 and 9.7 billion in 2050. It is estimated that to feed such a large population, global food production must be increased by 70%. at the same time, with the accelerating process of urbanization, the urban population is also increasing - by 2050, the global urban population will increase by 2.5 billion, and two thirds of the world's people will live in cities. In this case, the cultivated land area is bound to be squeezed, and the agricultural land in and around the city will be gradually eroded by the rising secondary and tertiary industries. there is no place to grow grain around the city
However, the sonar team, which led the team to discover the geometry of the sea floor in the area of about 2200 feet, was astonished by the fact that the sonar team was able to find the geometry of the sea floor in the area of about 2200 feet. National Geographic Channel of the United States has a great interest in this submarine archaeological site, and participated in the follow-up related exploration research. In 2003, a micro submarine explored the undersea site. Polina zilitsky of the advanced digital communications agency said the mysterious underwater site looked like a large ancient city center, but we can't judge it easily until we have the relevant evidence.
Will the Mariana Trench go deep into the earth's core? the Mariana Trench is the deepest trench known so far, with a depth of 6-11 km. If the Himalayas are put into it, the top of the Himalayas can be submerged. Due to the deep depth of the Mariana Trench, the temperature of the sea water here is extremely low, the pressure is very strong, and the solar photons can not reach here, so that it is dark all the year round, and the oxygen content is low. It is one of the worst places on earth. Although the Mariana Trench is the deepest place in the world, it is still a long way from the center of the earth. based on the available exploration data, we know that
Today, I'd like to introduce a kind of material. The name of this material is low-density ablative heat-resistant material. What is this material used for? What I introduce to you is its heat-resistant material, which can withstand the high temperature of 2000 degrees to protect the Shenzhou spacecraft to go home safely. Our spacecraft thermal protection material accounts for 45% of the weight of the whole system structure. If we reduce the density of this thermal protection material by 10%, we can also save 58 kg of weight, equivalent to the weight of an astronaut. Therefore, weight reduction is very necessary. Even if the replacement price is 8000 yuan per kilogram, it is still very cost-effective.
Now, a breakthrough research team from Tsinghua University, Beijing National Research Center for information science and technology, and the University of Delaware may accelerate the arrival of brain like computing and general artificial intelligence.

The main function of the kidney is metabolism. The kidney can also maintain the body's electrolyte and acid-base balance, generate urine, and maintain the body's water balance. But recently, a junior high school boy was diagnosed with renal failure, edema, delirium, the condition has reached uremia stage, after dialysis can only survive. These foods are high in protein and sugar, especially the excessive inorganic phosphorus in carbonated drinks. If ingested by the human body for a long time, it will bring serious pressure on the kidney. Over time, the renal function will become more and more fragile, and the renal failure will come uninvited.
