一 |     Colombo, Oct 17 (UNI) Sri Lanka saw its earnings from the tourism trade fall in September for a second consecutive month due to weaker arrivals ahead of a more prospective season which has got underway from the start of October and ends in January.
According to the data available through September, tourism trade has brought in $ 53.6 million in foreign exchange, bringing the cumulative nine-month earnings to $ 946.4 million, the Daily Mirror reported on Monday.
The September earnings were lower than both July and August when the figures for those two months were $ 85.1 million and $ 67.9 million respectively.
In the same month a year earlier, the trade had earnings of $ 35.3 million from 13, 547 visitors when the country was under lockdowns, the newspaper said.
In this September, 29,802 tourists travelled to Sri Lanka which was below 37, 760 arrivals in August and 47,293 arrivals in July.
Sri Lanka’s monthly arrivals exceeded 100,000 through March as the country got off to a fine start to tourism with high hopes of the foreign exchange it could generate in 2022, after two years of near decimation of the industry due to the pandemic, the report said.
In the nine months, Sri Lanka has welcomed 526,232 visitors as tourists.
With the start of the winter season in Europe, Sri Lanka is looking at a possible increase in bookings, specially from countries such as Germany and Switzerland.
UNI MR。    这项技术被称为"interiqr"（即"内部QR"），由日本大阪大学的一个团队开发。

二 | 作为概念验证，研究人员最近用3D打印了一些饼干，这些饼干外表光滑，看起来很正常，但内部却有一个空隙的图案。虽然这些图案在正常照明下看不到，但当从后面照明时，从正面看饼干，它们就会显示为“剪影的窗户”。然后，一个普通的智能手机能够读取这些代码，显示出其中存储的数据。

三 | 不用说，在其目前的形式下，该技术将被限制在相对较薄、有点半透明的3D打印食品中使用。尽管如此，科学家们希望它最终能够为制造商、零售商和消费者提供一种替代方法，以取代更浪费、更昂贵的方法，如常规应用于水果的纸质标签，或应用于包装的RFID标签。此外，如果成分和营养成分等信息可以由食品本身转达，那么就需要更少的包装来显示相同的数据。“我们的3D打印方法是食品数字化转型的一个很好的例子，我们希望这将改善食品的可追溯性和安全性，”该研究的高级作者佐藤浩介说。“这项技术还可以用来通过增强现实技术提供新颖的食品体验，这是食品行业中一个令人兴奋的新领域。”该团队将在本月晚些时候在第35届ACM用户界面软件和技术研讨会上发表一篇关于这项研究的论文。
