How much sleep is necessary Getting enough sleep is crucial for maintaining good physical and mental health. The amount of sleep required varies depending on age, lifestyle, and individual needs. The National Sleep Foundation provides the following guidelines for recommended sleep durations based on age: Newborns (0-3 months): 14-17 hours per day Infants (4-11 months): 12-15 hours per day Toddlers (1-2 years): 11-14 hours per day Preschoolers (3-5 years): 10-13 hours per day School-age children (6-13 years): 9-11 hours per day Teenagers (14-17 years): 8-10 hours per day Adults (18-64 years): 7-9 hours per day Older adults (65+ years): 7-8 hours per day It is essential to note that these are general recommendations and that individual needs may vary. Some people may require more or less sleep than what is recommended based on their lifestyle, health conditions, and other factors. Lack of sufficient sleep can have adverse effects on physical and mental health. Short-term effects include ...

 为什么中国可以主导电池的下一个重大进步 中国在开发使用钠的电池方面遥遥领先于世界其他国家，钠电池已开始与无处不在的锂动力电池展开竞争。 在中国内陆的长沙，成千上万的化学家、工程师和制造工人正在塑造电池的未来。 这座城市的中南大学培养了推动技术进步的毕业生，就像斯坦福大学塑造了开创微芯片的硅谷企业家的职业一样。 湘江对岸，大型工厂将矿物混合成高度加工的化合物，从而使充电电池成为可能。 这些电池主要由锂制成，推动了手机和其他消费电子产品的兴起。 他们正在改变汽车行业，并可能很快开始对应对气候变化至关重要的太阳能电池板和风力涡轮机进行同样的改造。 中国主导着他们的化学精炼和生产。 现在，中国正准备引领可充电电池的下一个重大创新：用钠替代锂，钠是一种更便宜、更丰富的材料。 钠作为盐的一部分在世界各地被发现，其售价是锂价格的 1% 到 3%，而且化学性质非常相似。 最近的突破意味着钠电池现在可以每天充电多年，削弱了锂电池的一个关键优势。 钠电池的能量容量也有所增加。 钠电池有一个很大的优势：当温度远低于冰点时，它们几乎可以保留所有电量，而锂电池通常不会这样做。 在长沙，中南大学绿树成荫的校园里的毕业生正在附近的研究实验室研究钠电池技术，这些实验室由全球最大的化学品制造商德国巴斯夫等公司运营。 距离实验室几个街区的第一批钠电池化学品大型工厂之一已经在建设中。 中国电池高管在接受采访时表示，他们在过去一年里已经弄清楚如何制造与锂电池非常相似的钠电池，以至于可以使用相同的设备制造。 全球最大的电动汽车电池制造商中国巨头宁德时代表示，它发现了一种在单个电动汽车电池组中同时使用钠电池和锂电池的方法，将钠电池的低成本和耐候性与锂电池的续航里程相结合 细胞。 该公司表示，现在准备批量生产这些混合电池组。 将钠用于电池的研究始于 70 年代，当时由美国领导。 十几年前，日本研究人员取得了重要进展。 此后，中国公司率先将这项技术商业化。 根据咨询公司 Benchmark Minerals 的数据，在全球目前计划或已经在建的 20 家钠电池工厂中，有 16 家在中国。 两年后，中国将拥有全球近95%的钠电池产能。 Benchmark 预测，届时锂电池的产量仍将超过钠电池的产量，但钠的进步正在加速。 在下周的上海车展上，预计汽车制造商和电池生产商将宣布计划在面向中国市场的至少一些限程超小...

“In one month, a vituber receives $134,000 and this figure is only growing,” who are vitubers and how does virtual reality replace ordinary bloggers? Even if you are not interested in trends on Youtube, you have probably seen videos with anime girls in the recommendations. Such content on video hosting is gaining millions of views and fans from different countries. The creators of such videos even got the name VTuber or vitubers. In this article, we will analyze who the vitubers are, how they appeared, how they became popular, and how difficult it is to create such an image for an ordinary person. What is VTuber? A vituber, or virtual YouTuber, is an online content creator who uses virtual avatars instead of his face. Virtual avatars are programmed to mimic the movements of the person behind the camera. Animated avatars usually resemble the appearance of anime characters from anime series or manga. They have big eyes, bright hair and a sonorous voice. They can be both 2D and 3D charact...

Summer Season The warm season is coming, which means that there is an opportunity to relax on nature and treat yourself to a dip in the sea or fresh water. Bathing is not only pleasant, but also useful. However, in order to get maximum benefit, and not harm your health, it is necessary adhere to certain rules of bathing hygiene. By themselves, water procedures in open water, as well as sunbathing on the beach, have a lot of positive effects for health. First, bathing, swimming is a physical activity, which is useful for both healthy and sick people. Secondly, being in the water and in the fresh air improves mood, appetite,relieve stress, generally have a positive effect on the nervous system, contribute to the production of vitamin D, improve metabolism. What are the rules for relaxing by the reservoir will help you with benefit and having fun while avoiding health problems? 1. Give preference to specially equipped beaches. The likelihood that on such beaches you can get injured on...
