Xin chào Buona,
Con trai tôi 2 tuổi, bé bị viêm mũi dị ứng từ bé. Hiện tại bé đã 2 tuổi nhưng thường xuyên bị viêm mũi dị ứng vào thời điểm giao mùa, hoặc mùa thu – đông. Bệnh ảnh hưởng nhiều đến khả năng hô hấp và phát triển của cháu. Vì vậy, tôi muốn sử dụng sản hẩm Nebial KIT để vệ sinh mũi cho bé hàng ngày, xin vui lòng tư vấn cách thức sử dụng?

Furthermore, the device supports grinding wheel balancing using three counterweights, providing flexibility for various balancing requirements. The Balanset-1A also features advanced charting capabilities, including overall charts that offer visual representations of total vibration, specific charts for fundamental frequency components, and harmonic frequency impact charts. Such graphical representations are invaluable for detailed analyses and diagnostics.
Enhancing its usability, the Balanset-1A features data archiving capabilities, allowing users to store and retrieve past sessions for ongoing analysis. It generates detailed reports that summarize balancing outcomes, streamlining the evaluation process and ensuring accuracy in documentation. The device also supports re-balancing for previously saved data, making it easier to maintain optimal machine performance over time.
In terms of technical specifications, the Portable Balancer is equipped with two vibration sensors, a laser tachometer, and a USB interface module that connects seamlessly to PC-based software for comprehensive analytics. This software can measure vibration, phase angles, and calculate correction mass values and angles, ensuring that users have access to complete data for their analysis.
The device can handle a range of RMS vibration velocity measurements from 0 to 80 mm/s, with a frequency range allowing vibration monitoring from 5 Hz to 550 Hz, and up to 1000 Hz for advanced applications. Additionally, the Portable Balancer supports both Imperial and Metric systems, catering to a global market and ensuring that users worldwide can benefit from its advanced capabilities.
Weighing just 4 kg, it is highly portable, allowing technicians to easily transport it to various job sites. With a power supply requirement of 140-220VAC and 50Hz, it can readily integrate into most industrial environments. This combination of portability, power, and precision positions the Balanset-1A as a leader in the field of balancing technology.
The Balanset-1A Portable Balancer ("Balanset") not only represents a significant advancement in vibration analysis technology but also embodies a commitment to quality and user-friendliness. This device has been developed to meet the increasing demands for expertise in dynamic balancing practices, ensuring that users can achieve optimal performance from their machinery and equipment.
In summary, the Portable Balancer and Vibration Analyzer Balanset-1A is your go-to solution for dynamic rotor balancing and vibration analysis. Its extensive features, dual-channel operation, comprehensive measurement capabilities, and user-oriented design make it an essential tool for technicians and engineers across a variety of industries. With the Balanset-1A, you can enhance operational efficiency, improve machinery longevity, and ensure compliance with industry standards seamlessly.

Tiny house with elaborate – and erotic – frescoes unearthed at Pompeii
[url=https://krmp12.cc]kraken зайти[/url]
Archaeologists have uncovered a tiny house in Pompeii that is filled with elaborate – and sometimes erotic – frescoes, further revealing the ornate way in which Romans decorated their homes.
Situated in the central district of the ancient city, the house is smaller than normal and unusually lacks the open central courtyard – known as an atrium – that is typical of Roman architecture, the Archaeological Park of Pompeii, which oversees the site, said in a statement Thursday.

This change could have occurred due to shifting trends in Roman – and particularly Pompeian – society, during the first century AD, archaeologists said.
Pompeii was destroyed by the eruption of Mount Vesuvius in AD 79 when its buildings and thousands of inhabitants were buried beneath layers of ash and pumice. This coating perfectly preserved the city for millennia, making it one of the most important archaeological sites in the world as it offers an unprecedented insight into Roman daily life.
This latest discovery spotlights the ornate decorations that rich Romans enjoyed in their homes – several frescoes depict mythical scenes and others are decorated with plant and animal motifs on a white background.
One small square painting set against a blue-painted wall depicts intercourse between a satyr and a nymph, while another shows Hippolytus, son of the mythical Greek king Theseus, and his stepmother Phaedra who fell in love with him before killing herself when he rejected her in disgust.
He served with the US Army in Iraq. Now he’s one of Asia’s top chefs and a Netflix ‘Culinary Class Wars’ judge

From a warzone in Iraq to a Michelin-starred kitchen and a hit Netflix show, chef Sung Anh’s path to the top of Asia’s fine dining scene has been anything but ordinary.
“Just like I did in the US Army, where I volunteered to go to the war, wanting to do something different — I decided to come here to Korea to try something different,” says the Korean-American chef and judge on hit reality cooking show “Culinary Class Wars,” which has just been green-lit for a second season.

Sung, 42, is the head chef and owner of South Korea’s only three-Michelin-starred restaurant, Mosu Seoul. In recent weeks, he has gained a new legion of fans as the meticulous and straight-talking judge on the new Netflix series. It’s this passion and unwavering drive to forge his own path that’s helped reshape fine dining in his birth home.
Born in Seoul, South Korea’s capital, Sung and his family emigrated to San Diego, California when he was 13.
“We were just a family from Korea, seeking the American Dream,” he says. “As an immigrant family, we didn’t really know English.”
As a teen growing up on the US West Coast, his mind couldn’t have been further from cooking.
“I went to school, got into college, but decided to join the US Army because that’s the only way I thought I could travel,” says the chef.
Over four years of service, he trained in bases across the country, before being deployed to his country of birth, South Korea and — following 9/11 — to the Middle East.
